Abstract: An ergonomic mouse has a sliding cap matching the curvature of a normal human palm. The sliding cap may be slid on the top of a hollow body to reach a desired operation position, then fine-tuned and anchored. Thus when the mouse is moved during operation, it can absorb reaction forces to avoid hurting the user's wrist and better meet ergonomic requirements.

Abstract: A portable electronic device includes a battery for providing electricity to the portable electronic device; a housing for accommodating the battery; a battery cover for covering the battery; a latch affixed to the housing in a slidable manner along a first direction, wherein when the latch is at a first position, the latch is capable of fixing the battery cover and the housing together; and an elastic unit for lifting the battery cover when the latch is at a second position.

Abstract: A structure for fastening a circuit board on a case includes a strut which has one end coupled on the case and other end coupled on the circuit board, and a coupling member which has two distal ends with surfaces not parallel with each other. One distal end is coupled on the circuit board with the distal end surface in parallel with the other end surface of the strut, and the other distal end surface is parallel with a holding section of a fastening element which fastens the coupling member, the circuit board and the strut in this order, to make the circuit board in parallel with a mounting surface, which an electronic device may be held on, of the case. The circuit board is easy to be fastened even if the circuit board is not vertical to the molding direction of the fastening structure. Assembly costs also are lower.

Abstract: A coupling structure for a handheld electronic device and a back cartridge thereof includes a first coupling assembly and a second coupling assembly. The first coupling assembly is located on the handheld electronic device. The second coupling assembly is located on the back cartridge corresponding to the first coupling assembly, and has a coupled position and a stored position. At the coupled position the second coupling assembly is extended outside the back cartridge to couple with the first coupling assembly, to thereby enable the handheld electronic device to couple with the back cartridge. At the stored position, the second coupling assembly is held in the back cartridge to allow the handheld electronic device to be separated from the back cartridge. Hence, the handheld electronic device and the back cartridge can maintain an integrated and self-contained profile.

Abstract: A docking station for handheld electronic devices includes a body which includes a guiding assembly having a first anchor member, and a holding section, and a sliding bracing cap which is movably mounted onto the body, and includes a driven member and a second anchor member respectively corresponding to the guiding assembly, and the first anchor member. The sliding bracing cap may be moved through the driven member along the guiding assembly to a retracted position, where the sliding bracing cap rests on the holding section to brace a handheld electronic device equipped with a back cartridge, and a bracing position, where the sliding bracing cap is anchored through the first and the second anchor members to brace a handheld electronic device without a back cartridge. Hence the device, either with or without a back cartridge, may be mounted securely onto the docking station of the structure without affecting transmission.
