Abstract: A secure electronic device with matching disassembling tool includes a housing and an electronic element. The disassembling tool includes a securing member, a first elastic disassembling member, and a second disassembling member. The securing member is mounted to the housing. The securing member includes an elastic locking block locked to the electronic element. The first elastic disassembling member can reach and be inserted into the securing member. The second disassembling member is inserted in the first disassembling member. When the second disassembling member is then rotated, the first disassembling member is deformed to press the elastic locking block, which unlocks from the electronic element.

Abstract: An electronic device includes a charge receiving coupler. The charge receiving coupler includes a switching assembly and an inserting member. The switching assembly includes a gear transmission shaft, an elastic member, a first transmission wheel, a second transmission wheel fixed to the first transmission wheel, a button gear, and a button fixed to the button gear. The button gear engages with the first transmission wheel. The gear transmission shaft extends through the elastic member, the first transmission wheel and the second transmission wheel in that order. The inserting member defines a receiving groove, and the second transmission wheel is partly received in the receiving groove. The present disclosure further provides a power adapter which is matched with the charge receiving coupler.

Abstract: An electronic device includes a housing, a pair of doors, and a memory. The doors are elastically and rotatably connected to the housing to shield the opening. Each door defines a guiding groove. When the memory card is inserted into the housing from the opening, the doors are rotated to open the opening, and the memory card is received in the guiding groove. When the memory card is removed from the housing, the doors shield the opening again so as to prevent contaminants from entering into the housing.

Abstract: An exemplary embodiment of an electronic device includes a cover including a first hole, and a heat dissipating assembly. The heat dissipating assembly includes a movable board including a second hole and slidably connected to the cover, and a heat magnifying device received inside the cover and adjacent to a heat element. The heat magnifying device includes a moving end secured with the movable board. When the heat element is maintained room temperature, the first hole and the second hole are staggered from each other to seal the cover. When heat generated by the heat element heats the heat magnifying device and causes the moving end of the heat magnifying device to move under thermal expansion and drive the movable board to slide relatively to the cover, and the first hole of the cover and the second hole of the movable board are communicated with each other.

Abstract: A holding device for holding a HDD includes two elastic members and two frame members. The HDD includes a first end and a second end. The two elastic members are configured for respectively encasing the first end and the second end. Each frame member includes a base portion, a first sidewall, a second sidewall, and at least one pair of clamping portions. The base portion includes a first surface and a second surface opposite to the first surface. The first and second sidewalls extend from two opposite ends of the base portion. The first sidewall, the second sidewall, and the first surface cooperatively define a groove for receiving a corresponding one of the two elastic members. The clamping portions in each pair of clamping portion extends out from the first sidewall and the second sidewall and configured for engaging with a corresponding pair of clamping portions of another frame member.

Abstract: A printed circuit board (PCB) bracket is used to fasten a PCB with a positioning hole to an enclosure of an electronic device. The PCB bracket includes a base portion defining a screw hole, a supporting arm, a spring arm and a screw. The supporting arm vertically extends from the base portion and includes a first clamping portion apart from and parallel with the base portion. The first clamping portion is inserted into the positioning hole. The spring arm includes a second clamping portion disposed between the first clamping portion and the base portion. The screw is screwed through the enclosure, the screw hole of the base portion and abuts against the urging portion, so that the spring arm is out of shape and drives the first clamping portion toward the second clamping portion so as to fasten the PCB.
