The present invention relates to fixing structures, and more particularly, to a fixing structure for assembling a battery module to an electronic device.
BACKGROUND OF THE INVENTIONWith development of the information technology, various kinds of electronic devices have been developed. In response to the requirement of expanding the amount of processing data and the operational efficiency, the electronic devices are necessarily provided with a sufficient supply of power. Besides having a power-saving design for the electronic device itself to allow power to be more effectively used, a common approach is to prepare a portable spare battery for the electronic device.
Taking an electronic device such as a desktop computer, a notebook computer or a server as an example, a cache memory is typically provided on a mainboard of the electronic device. When the electronic device is turned on, a power supply unit supplies power to the cache memory such that data can be temporarily stored in the cache memory without being vanished. However, when the electronic device is shut down, the cache memory no longer has power being supplied by the power supply unit, and the data stored in the cache memory are accordingly vanished. Therefore, in order to completely reserve the data, a cache memory battery module is usually provided in the electronic device.
A battery module is generally mounted in an electronic device by a fixing structure. As shown in
Although the use of screws provides a secure fixing effect, since an inner space of the server is normally small, any assistant tool such as a screwdriver entering the inner space of the server to lock the screws may easily touch an important component such as a mainboard of the server and cause damage to the server. Moreover, not all servers have enough space for allowing the screw-locking action to be easily performed therein. Thereby, it is complicated and time-ineffective to perform the fixing process with the screws, and it may happen during the fixing process that the screws drop into the server and cause electrically interrupt at some areas of the server. Accordingly, the conventional fixing structure using screws not only requires the assistant tool for assembly and disassembly of the battery module to and from the fixing structure, but also causes inconvenience in performing the fixing process.
Moreover, when the battery module is disassembled from the fixing mount of the above fixing structure by unscrewing the screws, this action may often be affected by the surroundings and cause drop or loss of the screws. Therefore, such conventional fixing technology using screws not only makes disassembling and assembling processes of the battery module to and from the fixing structure not time-effective to implement but also increases the cost for the screws if they drop or are lost.
Accordingly, there has been proposed another method for fixing a battery module to a fixing mount in an engagement manner. As shown in
However, it is found that the above engagement-fixing structure after being tested may have the battery module easily dropping from the fixing mount especially during movement of an electronic device provided with such battery module. Moreover, the elastic hook used in the engagement-fixing structure may easily become fatigued or may be cracked and broken if not being used properly. Accordingly, the fabrication cost is increased and the product yield is reduced, such that the above engagement-fixing mechanism is considered necessary to be improved for these drawbacks.
Therefore, the problem to be solved here is to provide a fixing structure for a battery module, which can overcome the foregoing drawbacks of the prior art.
SUMMARY OF THE INVENTIONIn light of the foregoing drawbacks of the prior art, an objective of the present invention is to provide a fixing structure for a battery module that can be assembled and disassembled to and from the fixing structure without any assistant tool.
Another objective of the present invention is to provide a fixing structure for a battery module to allow assembling and disassembling processes of the battery module to and from the fixing structure to be quickly and conveniently performed.
Still another objective of the present invention is to provide a fixing structure for a battery module, so as to well fix the battery module to an electronic device.
A further objective of the present invention is to provide a fixing structure for a battery module, so as to decrease the fabrication cost.
A further objective of the present invention is to provide a fixing structure for a battery module, so as to improve the product yield.
In order to attain the above and other objectives, the present invention proposes a fixing structure for a battery module having a first coupling portion and a second coupling portion.

The rotating member is pivotally mounted to the base, and includes a third fixing portion for being fixed to the first end of the first fixing portion, and a poking portion for allowing the third fixing portion to be separated from the first end of the first fixing portion.
Preferably, the first fixing portion and the second fixing portion are openings. The base further includes a first combining portion for being connected to the rotating member, wherein the first combining portion can be a stud. The third fixing portion of the rotating member can be a lug, a stopper, a bearing rib or a tenon. The rotating member further includes a second combining portion for being connected to the base, wherein the second combining portion can be a screw hole. The rotating member further includes a limit portion for limiting the third fixing portion, wherein the limit portion can be a lug, a stopper, a bearing rib or a tenon.
The battery module can be provided in an electronic device. By the above fixing structure of the present invention, the battery module can be assembled and disassembled to and from the fixing structure without any assistant tool, so as to easily fix the battery module in the electronic device by means of the fixing structure, such that the battery module can supply power to a cache memory of the electronic device to reserve data in the cache memory.
Compared with the prior art, by the fixing structure including the base and the rotating member according to the present invention, there is no need to use screws and various drawbacks caused by using the screws in the prior art can be eliminated, such as inconvenient in operation, time-ineffective assembly and disassembly processes, and increased cost for the screws, and so on.

In addition, a combining component 7 can be employed to pivotally mount the rotating member 13 to the base 11. When the rotating member 13 is inserted into the opening 117 of the base 11, and the second combining portion 135 of the rotating member 13 is put around the first combining portion 115 of the base 11, the rotating member 13 can be pivotally mounted to the base 11 by the combining component 7 that is coupled to the first combining portion 115 and the second combining portion 135. As shown in
The fixing structure 1 in this embodiment can be assembled with a battery module 3. The battery module 3 has a first coupling portion 31 and a second coupling portion 33. As shown in
When the first and second coupling portions 31, 33 of the battery module 3 are inserted into the first ends 1111, 1131 of the first and second fixing portions 111, 113, respectively, the rotating member 13 can be rotated, for example by finger(s), to allow the third fixing portion 131 to abut against the first coupling portion 31 and push the first coupling portion 31 into the second end 1113 of the first fixing portion 111, and simultaneously the second coupling portion 33 is operationally associated with the first coupling portion 31 and pushed into the second end 1133 of the second fixing portion 113, such that the first and second coupling portions 31, 33 are fixed by the second ends 1113, 1133 of the first and second fixing portions 111, 113, respectively, and at the same time the third fixing portion 131 of the rotating member 13 still abuts against the first coupling portion 31 to maintain the fixing status of the first and second coupling portions 31, 33.
Alternatively, when the first and second coupling portions 31, 33 of the battery module 3 are inserted into the first ends 1111, 1131 of the first and second fixing portions 111, 113, respectively, the battery module 3 can be moved, for example by finger(s), to push the first and second coupling portions 31, 33 into the second ends 1113, 1133 of the first and second fixing portions 111, 113, respectively, and then the rotating member 13 can be rotated to allow the third fixing portion 131 to abut against the first coupling portion 31, such that the first and second coupling portions 31, 33 are fixed by the second ends 1113, 1133 of the first and second fixing portions 111, 113, respectively, and the third fixing portion 131 abutting against the first coupling portion 31 maintains the fixing status of the first and second coupling portions 31, 33.
As shown in
It should be understood that the limit portion 137 and the fourth fixing portion 119, which are used to keep the third fixing portion 131 abutting against the first coupling portion 31 in this embodiment, may be modified in structure according to a structure of the electronic device or any other design requirements in other embodiments. For example, the limit portion 137 and the fourth fixing portion 119 may be modified to have mutually matching concave and convex structures, or any equivalent structure that can keep the third fixing portion 131 abutting against the first coupling portion 31 and also allow the third fixing portion 131 to be separated from the first end 1111 of the first fixing portion 111 after operating the poking portion 133 of the rotating member 13.
For example, as shown in
Thus, by operating or pressing/lifting the poking portion 133, the limit portion 137 can be moved to the one of the fourth fixing portions 119 where the third fixing portion 131 is kept abutting against the first coupling portion 31, or can be moved to the other one of the fourth fixing portions 119 where the third fixing portion 131 is allowed to separate from the first end 1111 of the first fixing portion 111.
When it is to disassemble the battery module 3 from the fixing structure 1, a user can simply operate the poking portion 133 with finger(s) to make the limit portion 137 separate from the fourth fixing portion 119 and associatively make the third fixing portion 131 separate from the first end 1111 of the first fixing portion 111 (for the embodiment shown in
The fixing structure 1 is assembled with the battery module 3 and then is mounted to the electronic device as described in the above embodiment. It should be understood that alternatively the fixing structure can be mounted to the electronic device before the battery module is assembled to the fixing structure. The order of steps of the assembling and disassembling processes in the present invention is not particularly limited to that described in the above embodiments.
