  • Patent number: 11953942
    Abstract: A foldable electronic device having multiple screens is provided. The foldable electronic device includes a first screen, a worm rod, a moving member, at least one second screen, and at least one linking rod. The worm rod is rotatably disposed on the first screen. The moving member is coupled to the worm rod to move along the worm rod when the worm rod rotates. The second screen is movably disposed on the first screen. The linking rod is pivotally connected between the moving member and the second screen. When the moving part moves along the worm rod, the second screen is driven to move away from or closed to the worm rod by the linking rod, so that the second screen moves out of the first screen or is accommodated behind the first screen.

  • Publication number: 20240111330
    Abstract: A foldable electronic device is provided, including a first body, a second body, a supporting member, a first hinge connecting the first body and the supporting member, a second hinge connecting the supporting member and the second body, and a gravity-type latch movably disposed in the supporting member. The first body and the supporting member are rotated relatively to be folded or unfolded via the first hinge, and the second body and the supporting member are rotated relatively to be folded or unfolded via the second hinge. In a transforming process of the first body folding to the supporting member and together unfolding relative to the second body, the gravity-type latch is latched onto the first body once the unfolding angle is less than a predetermined value, and the gravity-type latch is de-latched from the first body once the unfolding angle is equal to or greater than the predetermined value.

  • Publication number: 20240111339
    Abstract: A cabling structure of a foldable electronic device includes a first body, a second body, a hinge module connecting the first body and the second body, a sliding member movably disposed in the second body, a flexible electrical connecting member connected to the first body, the second body, and the sliding member and being driven when the first body and the second body are rotated relatively, and a restoring module disposed in the second body and providing a force to the sliding member. The first body and the second body are rotated relatively to each other through the hinge module. When being rotated relatively to each other, the first body and the second body drive the flexible electrical connecting member and the sliding member. The restoring module restores the sliding member and the flexible electrical connecting member via the force.

  • Patent number: 11942563
    Abstract: A manufacturing method of a chip package includes patterning a wafer to form a scribe trench, in which a light-transmissive function layer below the wafer is in the scribe trench, the light-transmissive function layer is between the wafer and a carrier, and a first included angle is formed between an outer wall surface and a surface of the wafer facing the light-transmissive function layer; cutting the light-transmissive function layer and the carrier along the scribe trench to form a chip package that includes a chip, the light-transmissive function layer, and the carrier; and patterning the chip to form an opening, in which the light-transmissive function layer is in the opening, a second included angle is formed between an inner wall surface of the chip and a surface of the chip facing the light-transmissive function layer, and is different from the first included angle.

  • Publication number: 20240098932
    Abstract: A foldable electronic device, including a first body, a second body, an air valve movably disposed in the first body, at least one triggering member, and a hinge connecting the first body and the second body, is provided. The first body has multiple openings respectively located at two opposite surfaces. The triggering member is movably disposed in the first body and has a part exposed outside the first body. The air valve and the triggering member are mutually on moving paths of each other. The first body and the second body are rotated to be folded or unfolded relative to each other by the hinge. A part of the triggering member is suitable for bearing a force such that the triggering member drives the air valve, so that the air valve opens or closes the openings.

  • Patent number: 11934223
    Abstract: A foldable electronic device, including a first body having a first shaft member, at least one second body having a second shaft member, and a latching member, is provided. The first shaft member and the second shaft member are coaxially pivoted together. The first shaft member has a recess. The second shaft member has a locking hole. The latching member is movably disposed in the recess and the locking hole, so that when the latching member leaves the locking hole, the first body and the second body are relatively pivoted through the first shaft member and the second shaft member, or when the latching member moves into the locking hole, the latching member interferes with the first shaft member and the second shaft member to block the first body and the second body from relatively pivoting.

  • Patent number: 10635034
    Abstract: A fixation device performing a fixation process on a medium in conjunction with a pressure roller includes: a fuser heating to a predetermined temperature to perform the fixation process; a temperature sensor senses a temperature of the fuser as time elapses; a controller electrically connected to the fuser and the temperature sensor; and a database connected to the controller and storing heating time data; wherein the controller obtains a heating time period, during which a temperature of the fuser rises from a non-environment temperature to the predetermined temperature, through the temperature sensor, and judges whether the heating time period falls within a qualified range specified by the heating time data. If the heating time period does not fall within the qualified range, then the controller provides an abnormal message, so that the problem of the fixation device can be solved.
