[0015] By adopting the above technical solution, the rotation of the rotating part drives the driving cam to rotate, and the driving cam rotates and pushes the lock tongue to move until the driving cam is pressed against the inner wall of the length side of the mounting hole. At this time, the lock tongue is completely disengaged from the locking groove, thereby realizing the unlocking of the lock tongue.
[0016] Optionally, the positioning member is a right-angle torsion spring, which is coaxially sleeved on the rotating member, and one end of the right-angle torsion spring is fixedly connected to the protruding part of the driving cam. In the locked state, the other end of the right-angle torsion spring is vertically pressed against the inner wall of the mounting hole near the locking groove.
[0017] By adopting the above technical solution, when in the locked state, the two ends of the right-angle torsion spring are respectively pressed against the two inner walls of the mounting hole that are perpendicular to each other, thereby improving the stability of the lock tongue. When unlocking, the right-angle torsion spring rotates with the rotating part until the driving cam is pressed against the inner wall of the length side of the mounting hole. At this time, the other end of the right-angle torsion spring faces the inner wall of the width side of the mounting hole. The right-angle torsion spring is used to improve the locking stability of the lock tongue and reduce the probability of the lock tongue being accidentally unlocked by external force, thereby improving the safety of the electronic padlock.
[0018] Optionally, a lock tongue in place sensor is provided on the inner wall of the sliding cavity, a central control unit is provided in the lock body, the lock tongue in place sensor signal input end is used to interfere with the lock tongue, the lock tongue in place sensor output end is connected to the signal input end of the central control unit, and the control end of the central control unit is electrically connected to the enable end of the motor.
[0019] By adopting the above technical solution, when unlocking, the motor starts and drives the lock tongue to move through the rotating part. After the lock tongue moves to contact the lock tongue in place sensor, the lock tongue in place sensor transmits a signal to the central control unit. The central control unit controls the motor to stop, and the lock tongue rebounds under the action of the reset spring. Since the lock beam has popped out, the lock tongue hits the side wall of the lock beam close to the mounting hole after rebounding, thereby realizing the control of the lock tongue moving into place and improving the convenience of unlocking the lock tongue.
[0020] Optionally, the pop-up mechanism includes:
[0021] A limit pin, wherein the limit pin is fixedly arranged in the lock body, and a limit groove and a positioning groove are sequentially provided on the outer side wall of the lock beam located in the lock body from top to bottom, wherein the limit groove is located below the locking groove and extends vertically, and the positioning groove is annular and communicated with the limit groove, and when locked, the limit pin abuts against the limit groove, and when unlocked, the limit pin abuts against the bottom wall of the positioning groove and is used to prevent the lock beam from popping out;

At this time, the reset spring 43 is compressed, the pop-up spring 62 rebounds and pushes the lock beam 2 to pop out, and the lock beam 2 drives the locking part 22 to disengage from the locking groove 12, thereby realizing the unlocking of the padlock. When the lock tongue 3 moves to collide with the lock tongue in place sensor 19, the lock tongue in place sensor 19 transmits a signal to the central control unit, and the central control unit controls the motor 18 to turn off. Then the reset spring 43 rebounds to make the lock tongue 3 move back. The return movement of the lock tongue 3 drives the driving cam 42 and the right-angle torsion spring 51 to rotate. Since the lock beam 2 has popped out at this time, the lock tongue 3 rebounds to collide with the outer wall of the lock beam 2. At this time, the right-angle torsion spring 51 is located between the length side and the width side of the mounting hole 31. When locking is required, press the lock beam 2.
[0065] In other embodiments, in order to prevent the driving cam 42 from excessive rotation, a limit block is provided at the bottom of the lock tongue 3 for limiting the rotation of the driving cam 42. In the locked state, the angle between the limit block and the limit cam is greater than 90° and less than 120° (not shown in the figure).
[0066] The models of the relevant sensors in this embodiment are not intended to limit the present application, and in other embodiments, sensors of different models with corresponding functions may be selected as replacements.
[0067] The working principle of the embodiment of the present application is as follows:
[0068] When in the locked state, the lock tongue 3 is inserted into the locking groove 21, the locking part 22 is inserted into the locking groove 12, the pop-up spring 62 is compressed, the limit pin 61 is located in the limit groove 23, and the protruding part of the driving cam 42 is pressed against the inner wall of the width side of the mounting hole 31. At the same time, the end of the right-angle torsion spring 51 away from the driving cam 42 is vertically pressed against the inner wall of the mounting hole 31 close to the locking groove 21. When the lock tongue 3 is subjected to an external force opposite to the locking direction, since the rotating part 32 does not rotate, the right-angle torsion spring 51 continues to press against the mounting hole 31, thereby blocking the movement tendency of the lock tongue 3 and reducing the probability of the lock tongue 3 being accidentally unlocked by external force, thereby improving the safety of the electronic padlock.
[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
