FIELD

The present disclosure relates to a chassis design with a designated space for cable routing and a power supply socket.

BACKGROUND

Space on a computer sled is highly desired, as conventional computer chassis demand greater complexity and variety of computer components on their sleds. Conventional computer chassis hold sleds housing a plurality of computer components. The computer chassis must be electrically powered to operate these components. Conventional computer chassis therefore provide narrower sleds to make space for a power supplier socket and any cabling along one edge of the computer chassis. Typically, the power supplier socket has a wider width than the cabling running to and from the socket. This disparity between the width of the power supplier socket and the cabling leads to a gap of unused space in the computer chassis along the length of the cabling and behind the power supplier socket.

Furthermore, conventional computer sleds are frequently loaded and unloaded from their corresponding chassis due to maintenance requirements or requests to change the components on the sled. Unloading a sled can be complicated and time-intensive for a user due to the cabling attached to various components on the sled. A user needs to remove the cabling, unload the sled, replace the computer components, reattach the cabling, and load the sled back into the chassis.

Therefore, an apparatus design is needed to make use of the space behind the power supplier socket.

SUMMARY

The various examples of the present disclosure are directed towards a computer chassis which includes a sled and a sliding rail bracket. The sliding bracket can have a first end and a second end, where the first end includes a removable power supplier socket. The removable power supplier socket can be configured to move out of the computer chassis via a set of mechanisms. Upon removing the power supplier socket from the computer chassis, the sled can be pulled out of the computer chassis.

In some examples, the set of mechanisms can include a rotational element and a first elastic element. A loaded position of the first elastic element can bias the power supplier socket to rotate away from the sled. In some examples, the rotational element can include an axis mechanically coupled to the first elastic element. The power supplier socket can rotate about the axis when moving into or out of the chassis.

In some examples, the sliding bracket can further include a sliding return lever. The sliding return lever can include a second elastic element and a pivot mechanism. Transitioning the sled into an unloaded position can cause the pivot mechanism to unload the second elastic element, as an edge of the sled passes a midpoint of the pivot mechanism. In a corresponding fashion, transitioning the sled into a loaded position can cause the pivot mechanism to load the second elastic element when an edge of the sled passes a midpoint of the pivot mechanism.

In some examples, unloading the second elastic element can cause the second elastic element to exert force on the sled; the exerted force can drive the sled out of the computer chassis.

In some examples, the sled can be indented around the removable power supplier socket. Between the sled and the sliding bracket, the computer chassis can further provide an opening configured to receive a cable.

In some examples, the sled can slide along the sliding bracket when transitioning between a loaded and an unloaded position. The sliding bracket can be configured to slidably extend along an interior edge of the computer chassis. The sliding bracket can include a stopping mechanism at the second end, configured to catch an edge of the sled as the sled is transitioning between a loaded and unloaded position.

 DETAILED DESCRIPTION

The present invention is described with reference to the attached figures, where like reference numerals are used throughout the figures to designate similar or equivalent elements. The figures are not drawn to scale, and are provided merely to illustrate the instant invention. Several aspects of the invention are described below with reference to example applications for illustration. It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the invention. One having ordinary skill in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details, or with other methods. In other instances, well-known structures or operations are not shown in detail to avoid obscuring the invention. The present invention is not limited by the illustrated ordering of acts or events, as some acts may occur in different orders and/or concurrently with other acts or events. Furthermore, not all illustrated acts or events are required to implement a methodology in accordance with the present invention.

The present disclosure provides for a computer chassis design which includes a sled and a sliding bracket. The sliding bracket can include a removable power supplier socket on a first end and a sliding return lever on the second end. When the sled is removed from the computer chassis, the removable power supplier socket can move out of the chassis via a set of mechanisms. The set of mechanisms can include an elastic element to cause the power supplier socket to automatically rotate out of the chassis. This automatic movement of the power supplier socket allows the sled to be easily pulled out of the chassis, even if the sled is shaped to extend behind the power supplier socket. Therefore, the present disclosure also provides for a sled shaped with an option behind the power supplier socket. This disclosed computer chassis design provides for both: (1) an increased amount of available space on the sled; and (2) an ease of loading and unloading the sled from the computer chassis. The increased amount of available space can be used to hold more electronic components, including, for example, dual in-line memory modules.

FIG. 1 shows a conventional computer chassis 100, according to the prior art. Chassis 100 can include a sled 110, a power supplier socket 120, a cable routing portion 130, and a chassis body 140. The sled 110 can house computer components (not pictured). The power supplier socket 120 can receive cables from the cable routing portion 130, and provide power to the components in the sled 110.

In a conventional chassis 100, the sled 110 takes up the majority of space in the chassis body 140, but the sled 110 is designed to be narrow enough to leave space in the chassis body 140 for the power supplier socket 120 and the cable routing portion 130. In conventional chassis 100, the sled 110 can slide into and out of the chassis body 140, and the sled 110 is sized so as to not overlap with the power supplier socket 120. Therefore, the power supplier socket 120 remains in place as the sled 110 loads or unloads from the chassis body 140.

Typically, a power supplier socket 120 is wider than the cables running to and from the power supplier socket 120, in the cable routing portion 130. Such a design, as shown in FIG. 1, results in empty space 140a in the chassis body 140, which is not used by the sled 110, and does not contain any computer components. Thus, empty space 140a does not provide an efficient use of the area provided in a conventional chassis body 140.

In response to the space limitations of conventional computer chassis shown in FIG. 1, the present disclosure provides for an exemplary computer chassis that makes use of the space 140a. FIG. 2 shows an exemplary computer chassis 200, according to an embodiment the present disclosure. Chassis 200 comprises a sled 210, an indented portion 212, extended space 214, a removable power supplier socket 220, a cable routing portion 230, and a chassis body 240.

The sled 210 can house computer components, be received into a chassis body 240, and allow space in the chassis body 240 for cable routing portion 230. Sled 210 provides a different design than the conventional sled 110 (of FIG. 1), because sled 210 includes an indented portion 212 and extended space 214. The indented portion 212 allows the sled 210 to extend beyond the removable power supplier socket 220, which provides extended space 214 on the sled 210 where additional components can be housed. Therefore, sled 210 provides a greater area for housing computer components than the conventional sled 110 shown in FIG. 1. The removable power supply socket 220 can be configured to automatically move into and out of the chassis body 240, according to the mechanisms discussed below with respect to FIGS. 3A-5D.

FIGS. 3A-5D show cut-away views of various positions of the computer chassis of FIG. 2, according to various embodiments of the present disclosure. FIGS. 3A-5D can include many components and similar labels to components in FIG. 2. In addition, FIGS. 3A-5D show a sliding rail bracket 310, a sliding return lever 320, a set of mechanisms 330, a stopping mechanism 340. The sliding return lever 320 can include an elastic element 410 and a pivot mechanism 420; the set of mechanisms 330 can include an elastic element 430 and a rotational element 440.

FIG. 3A shows an entirely-loaded position 300A of the disclosed chassis, where the removable power socket 220 is fully received within the chassis 240. The disclosed chassis of FIG. 2 can include a sliding rail bracket 310 along an interior edge 240a of the chassis body 240. The sled 210 can slide along the sliding rail bracket 310 when loading into and out of chassis body 240. The sliding rail bracket 310 can also be coupled to a removable power supply socket 220 via a set of mechanisms 330 (discussed further with respect to FIG. 3B) located at a first end 310a of the sliding rail bracket 310. A second end 310b of the sliding rail bracket 310 can provide a stopping mechanism 340 (discussed further with respect to FIG. 5D).

Lastly, sliding rail bracket 310 can include a sliding return lever 320 along a length of the sliding rail bracket 310 (discussed further with respect to FIG. 3B). The sliding return lever 320 can be fixed within the chassis body 240, so that movement of the sled 210 does not cause the sliding return lever 320 to move. In some examples of the present disclosure, the sliding return lever 320 can be fixed at a particular distance 320a from the second end 310b of the sliding rail bracket 310. The particular distance 320a can be a length of the removable power supplier socket 220.

FIG. 3B shows a partially-unloaded position 300B of the disclosed chassis, where the sled 210 is unloaded from the chassis body 240 so that the removable power supply socket 220 is fully outside of the chassis body 240. When the removable power supply socket 220 is outside of the chassis body 240, the rear edge 210a of the sled 210 engages with the sliding return lever 320.

FIG. 3B further shows a close-up view of the sliding return lever 320, which includes an elastic element 410 and a pivot mechanism 420. The pivot mechanism 420 can have a first portion 420a, which receives the sled 210 as it is loaded into the chassis body 240. A second portion 420b of the pivot mechanism can be coupled to the elastic element 410. Referring momentarily to FIG. 5A, the sliding return lever 420 can be configured so that when the first portion 420a receives the sled 210 as it is loaded into the chassis body 240, the first portion 420a can move towards the elastic element 410. The movement of the first portion 420a can pivot the second portion 420b away from the elastic element 410, which consequently loads the elastic element 410. The elastic element can be an extension spring, for example. In other examples, the elastic element 410 can be any elastomer configured to be loaded when the sled 210 is loaded into the chassis body 240.

Referring back to FIG. 3B, the set of mechanisms 330 can include an elastic element 430 and a rotational element 440. The rotational element 440 can be a joint through which a portion of the elastic element 430 extends. The elastic element 430 can have a first portion 430a extending along a length of the removable power socket 220, and a second portion 430b extending towards the body of the removable power socket 220. Elastic element 430 in an unloaded position, where the removable power supplier socket 220 is configured to rotate away from the sled 210 due to the elastic force of the elastic element 430. The elastic element 430 can be loaded when the power supplier socket 220 is rotated towards the sled 210 (for example, when a user is loading sled 210 into the chassis body 240). For example, the elastic element 430 can be a compression spring. In other examples, the elastic element 430 can be any elastomer configured to be loaded when the power supplier socket 220 is rotated towards the sled 210.

FIG. 4 shows an exemplary computer sled transition 400, where the sled 210 transitions from a loaded position in chassis body 240 to an unloaded position. As the sled 210 is pulled out of the chassis body 240, elastic element 410 biases the first portion 420a of pivot mechanism 420 to rotate away from the sliding bracket 310, towards the sled 210. When the rear edge 210a of the sled 210 passes over a midpoint 420c of the pivot mechanism 420, the elastic element 410 can unload, and can exert force moving the sled 210 out of the chassis body 340, along the sliding bracket 310. When the power supplier socket 220 is out of the chassis body 240, the elastic element 430 can exert force on the power supplier socket 220, causing the power supplier socket 220 to rotate away from the chassis body 240. Therefore, elastic elements 410 and 430 can contribute to automatic unloading of the sled 210 from the chassis body 240.

FIG. 5A shows an exemplary computer sled transition 500A, where the sled 210 transitions from an unloaded position to a loaded position. As discussed earlier with respect to FIG. 3B, the first portion 420a of the pivot mechanism 420 can be pushed towards the sliding bracket 310 as sled 210 is loaded into the chassis body. This can load the elastic element 410.

FIG. 5B shows an exemplary computer sled transition 500B. Transition 500B follows after transition 500A where sled 210 is pushed just past a midpoint 420c of pivot mechanism 420. Therefore, when sled 210 is loaded in chassis body 240, elastic element 410 will be loaded. Removable power socket 220 can be rotated towards computer sled 210 as sled 210 is loaded into chassis body 240.

FIG. 5C shows an exemplary computer sled transition 500C where sled 210 is fully loaded into chassis body 240. Transition 500C can occur after transition 500B. Elastic element 430 is compressed against an interior edge 240a of chassis body 240.

FIG. 5D shows how the stopping mechanism 340 is of a sufficient length to extend from the sliding rail bracket 310 to the sled 210. The stopping mechanism 340 can receive a rear edge 210a of the sled 210 as the sled 210 is being loaded into the chassis body 240. Thereby, loading the sled 210 into the chassis body 240 can cause the sliding rail bracket 310 to slidably extend along the interior edge 240a of the chassis body 240.

Altogether, FIGS. 5A-5D show that sliding return lever 320 and mechanism 330 provide an apparatus to load and unload the computer sled without interference from the power supplier socket. This allows the disclosed chassis to make use of the space behind the power supplier socket, which is typically unused in conventional chassis designs.
