[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below.

[0019] See figure 1 with figure 2 The anti-vibration electric control lock shown includes a lock shell 100 corresponding to the lock hook 200 of the door body and a hook lever 300 rotatably arranged in the lock shell 100 by a reset torsion spring 110. The hook lever 300 has a groove 310 corresponding to the lock hook 200 and a hook lever stop surface 320, and a power module 400 and a circuit board 500 are arranged in the lock housing.

[0020] The hook lever stop surface 320 has a transition arc surface 321, and an unlocking stop portion 322 and an upper locking stop portion 323 respectively located at both ends of the transition arc surface 321. The unlocking stop portion 322 and the upper lock stop in this embodiment The moving parts 323 are stop edges with curvatures. The hook lever stop surface 320 may be provided on the upper end or the lower end of the hook lever 300. This embodiment takes the case where the hook lever stop surface 320 is provided on the upper end of the hook lever 300 as an example.

[0021] The lock housing 100 is also provided with a first elastic limiting component 600 and a second elastic limiting component 700. One end of the first elastic limiting component 600 corresponds to the unlocking stop portion 322 and the upper locking stop portion 323, respectively. The other end of the first limit elastic component 600 is in position-limiting fit with one end of the second limit elastic component 700, and the other end of the second limit elastic component 700 is connected to one end of the shape memory alloy component 800. The other end is a fixed end. The power module 400 is electrically connected to the shape memory alloy component 800, the power module 400 is connected to the shape memory alloy component 800 through wires 1 and 2, and the circuit board 500 is connected to the power module 400.

[0022] Preferably, the first limit elastic component 600 in this embodiment includes a first push rod 610 and a first compression spring 620 sleeved on the first push rod 610, one end of the first compression spring 620 is a fixed end, and the other One end is matched with the limit step 611 on the first top rod 610. The second limit elastic component 700 includes a second top rod 710 and a second compression spring 720 sleeved on the second top rod 710. One end of the second compression spring 720 is a fixed end, and the other end is connected to the second top rod 710. The limit step 711 matches. The first jack 610 and the second jack 710 are perpendicular to each other, and the other end of the second jack 710 is connected to one end of the shape memory alloy component 800. The shape memory alloy component 800 is a shape memory alloy wire, of course, it can also be a spring made of a shape memory alloy material or a strip made of a shape memory alloy material.

[0023] In order to control the rotation range of the hook lever 300, a limit edge 120 for restricting the excessive rotation of the hook lever 300 is also provided in the lock housing 100.

[0024] In order to increase the amount of deformation of the shape memory alloy component 800, the shape memory alloy component 800 is turned around by at least one pulley 130 disposed in the lock housing 100.

[0025] In order to prevent the power supply from being unable to unlock, the lock housing 100 is also provided with an emergency opening 140 on the side of the second elastic component 700, and the second elastic component 700 can be manually driven to move through the emergency opening 140 , To release the restriction on the first restriction elastic component 600.

[0026] A micro switch 900 corresponding to the dial block 330 on the hook lever 300 is also provided in the lock housing 100. The micro switch 900 can be connected to a computer management system to facilitate the system to manage and record the opening and closing of the door cabinet. When the hook lever 300 is in the locked state, the shift block 330 will not interfere with the micro switch 900, and when the hook lever 300 is in the unlock state, the shift block 330 will interfere with the micro switch 900.

[0027] The working principle of the present invention is as follows:

[0028] Combine figure 1 As shown, when the hook lever 300 is in the locked state, the lock hook 200 at this time is inserted into the slot 310, and the slot 310 restricts the lock hook 200 from coming out. Under the elastic force of the first compression spring 620, one end of the first jack 610 cooperates with the upper locking portion 323 to limit the position, and at this time, one end of the second jack 710 is under the elastic force of the second compression spring 720 The horizontal jack is on the other end of the first jack 610 to prevent the other end of the first jack 610 from shifting upward.

[0029] Combine figure 2 As shown, when the hook lever 300 needs to be in the unlocked state, the electronic card is placed on the electronic card swiping sensing area of the circuit board 500, and the circuit board 500 will make the power module 400 supply power to the shape memory alloy component 800. 800 is energized and shortened, driving the second top rod 710 to move backwards, releasing the restriction on the other end of the first top rod 610, the hook lever 300 rotates under the action of the reset torsion spring 110 and pushes the lock hook 200 out of the lock housing. At the same time, one end of the first jack 610 passes through the transition arc surface 321 and cooperates with the unlocking stop 322 to limit the position, and waits for the next locking state.

[0030] The above shows and describes the basic principles and main features of the present invention and its advantages. Those skilled in the industry should understand that the present invention is not limited by the foregoing embodiments. The foregoing embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have Various changes and improvements, these changes and improvements all fall within the scope of the claimed invention.
