Abstract: The present application relates to an avalanche infrared detector and a preparation method thereof. In the present application, a homogeneous structure is constructed based on an atomic layer number-dependent energy band structure of a two-dimensional van der Waals material, which can solve problems such as lattice mismatch and defects of the traditional heterojunction avalanche photodetectors and can inhibit the generation of main dark current components such as recombination current and tunneling current by detectors. A “peak” electric field at a stepwise homojunction interface is adopted to enhance a coulomb interaction between carriers, inhibit the hot carrier-phonon coupling, and reduce an energy loss caused by a relaxation process.

Abstract: A shock absorbing device comprises a shock absorbing device body, which comprises an upper shock absorbing cover and a lower shock absorbing cover, a primary shock absorbing element and a secondary shock absorbing element located on the outside of a circle of the primary shock absorbing element are arranged between the upper shock absorbing cover and the lower shock absorbing cover; a tower spring is matched with a plurality of shock absorbing silicones to effectively reduce the shock transfer between the upper shock absorbing cover and the lower shock absorbing cover; the upper shock absorbing cover and the lower shock absorbing cover are not directly connected with mother and child limit screws, but are connected with the mother and child limit screws through the shock absorbing silicones; a shock absorbing spring can assist the shock absorbing silicones to buffer the shock and shape the shock absorbing silicone.

Abstract: The present invention discloses a quick-release tablet protection stand system, relating to the field of electronic product accessories. The quick-release tablet protection stand system comprises a quick-release detachable stand, which is movably installed inside the protective case. The quick-release detachable stand consists of a stand top plate and a stand base plate positioned on one side of the top plate. The stand switch is designed with a push-button mechanism for control, which, compared to the conventional press-button design, reduces the risk of accidental activation. This prevents the sudden collapse of the extended stand due to accidental touches and protects the tablet from tipping over or falling and causing damage, making it safer to use. The shock-absorbing stand is connected to the adjustable mechanism through a docking buckle, docking holes, and locking screws, making assembly and disassembly faster.

Abstract: The present invention discloses a shock-absorbing and magnetic quick release system, which relates to the technical field of electronic product accessories. The system comprises a magnetic quick release mechanism and a shock-absorbing mechanism. The magnetic quick release mechanism comprises a fixing seat and a quick release plate, and the opposite surfaces of the fixing seat and quick release plate are embedded with magnets for attracting each other. The fixing seat has an internal slot. The quick release plate can be separated from the fixing seat by gripping quick release buttons to drive buckles out of locking holes to achieve a quick release. When installing the quick release plate, the magnetic function can directly drive the locking holes to lock the buckles, so the installation is quicker. The shock-absorbing mechanism can help to buffer the vibration transmitted by the magnetic quick release mechanism, reducing potential damages to smart devices.

Abstract: The present disclosure discloses a fixed quick-release apparatus. It includes: a gear turntable, configured to connect a cycling bracket, where a limiting gear ring is disposed on a top circle of the gear turntable; a housing, configured to mount the gear turntable; and a gear stand, mounted inside the housing, where a positioning gear ring that is opposite to the limiting gear ring is disposed on a bottom circle of the gear stand, an anti-rotation plate is disposed at a top of the gear stand, and a limiting spring, disposed at a bottom of the gear stand. Because the gear stand is driven to move by pressing the button, the positioning gear ring is engaged with the limiting gear ring, to limit rotation of the locking turntable and the unlocking of the anti-rotation plate on the terminal device. Because the spring steel beads abut against the arc-shaped groove, the terminal device can be adjusted and positioned by rotating 360°.
