[0002] With the development of society, electronic locks are becoming more and more popular, and there are many types of electronic locks. In this fiercely competitive market, the stability, sensitivity, energy saving and durability of electronic locks have become the focus of research by various manufacturers. However, at present, most electronic locks' clutch control mechanisms generally use gear reduction micro-motor drive devices to push the clutch pin to separate or close the mechanism mechanically, and control the opening and closing of the electronic lock control mechanism by controlling the motor switch. Some use travel switches for control, but the structure is relatively complicated.

[0003] The driving device in this traditional electronic lock will generate friction due to the mutual fit between the gear sets and the change of circular rotation into linear motion, which greatly consumes electrical energy and motor torque. This not only causes the limited battery life of the electronic lock to be too short and is prone to noise, but also easily causes wear of the micromotor gear set and instability of the electronic lock driving device. In order to solve the above problems, we propose an electronic lock driving device. Utility Model Content

The tendency of locking; a sliding block 3 is slidably arranged in the upper base 1, wherein a baffle 306 for limiting the rotation of the lock tongue seat 2 is fixedly arranged on one end of the sliding block 3, and when the baffle 306 abuts against the lock tongue seat 2, the rotation of the lock tongue seat 2 can be limited, so that the lock tongue seat 2 is in a locked state, a motor 4 is fixedly arranged in the lower base 101, and an eccentric shaft 401 for driving the sliding block 3 to slide is fixedly arranged at the output end of the motor 4, and the eccentric shaft 401 is driven to rotate by the motor 4, so that the sliding block 3 can be driven away from the lock tongue seat 2 to achieve unlocking, and a push rod 303 is fixedly arranged on the sliding block 3, and one end of the push rod 303 away from the sliding block 3 extends to the outside of the upper base 1, and the unlocking can be achieved manually, thereby improving the use effect.

[0027] When in use, an eccentric shaft 401 is fixedly arranged at the output end of the motor 4. When the motor 4 drives the eccentric shaft 401 to rotate and the circumference of the eccentric shaft 401 abuts against the side wall of the driving groove 301, the sliding block 3 can be driven away from the lock tongue seat 2 to achieve unlocking. The structure is simple, the driving effect is reliable, and the friction is small, which can reduce the power consumption and the noise is also small, which helps to improve the stability during use.

[0028] Reference Figure 2-Figure 4 A connecting rod 304 is fixedly provided at the other end of the sliding block 3, and a spring is sleeved on the connecting rod 304, and the two ends of the spring are respectively against the sliding block 3 and the upper base 1. When in use, by arranging a spring at the other end of the sliding block 3, on the one hand, when the motor 4 stops driving the eccentric shaft 401 to rotate, it is convenient to drive the sliding block 3 to reset. On the other hand, in the absence of external force, the baffle 306 can always be in a limiting state of the extension block 202, thereby ensuring the reliability of the locking state of the lock tongue seat 2.

[0029] Reference Figure 2-Figure 4A limiting rod 104 is fixedly arranged in the upper base 1, and a waist-shaped hole 305 is opened on the sliding block 3.

The limiting rod 104 is slidably connected in the waist-shaped hole 305, and the outer wall of the limiting rod 104 is tangent to the inner walls on both sides of the waist-shaped hole 305. When in use, by opening the waist-shaped hole 305 on the sliding block 3 and fixing the limiting rod 104 in the upper base 1, on the one hand, the sliding block 3 can be guaranteed to slide reliably to prevent deflection and affect normal use. On the other hand, the sliding block 3 can also be limited to avoid excessive sliding toward the lock tongue seat 2.

[0030] Reference Figure 2-Figure 4 A driving groove 301 is provided on the end face of the sliding block 3 close to the baffle 306, and the circumference of the eccentric shaft 401 is abutted against the side wall of the driving groove 301.

[0031] Reference Figure 2-Figure 4 A limit plate 302 is fixedly arranged at the bottom of the baffle 306, and the side wall of the limit plate 302 abuts against the circumference of the eccentric shaft 401. When in use, the limit plate 302 can be set to limit the rotation angle of the eccentric shaft 401, so that its rotation range is less than 360 degrees. When unlocking, the motor 4 is first started to drive the eccentric shaft 401 to rotate from one side of the limit plate 302 to the other side. During the process, the eccentric shaft 401 can push the sliding block 3 to translate in the opposite direction, that is, away from the direction of the lock tongue seat 2, until the lock tongue seat 2 is free from the limit of the baffle 306, and the lock tongue seat 2 is rotated clockwise by the elastic force of the torsion spring. The unlocking is completed. At this time, when the eccentric shaft 401 pushes the sliding block 3 in the opposite direction to the extreme position, the eccentric shaft 401 continues to rotate, and the sliding block 3 is reset under the push of the spring. At this time, the motor 4 drives the eccentric shaft 401 to rotate to the other side of the limit plate 302 and hits the limit plate 302. After the electronic control unit senses the voltage change in the motor 4, it immediately controls the motor 4 to reverse 30 degrees and then stop. At this point, the electronic control unit adopts the existing technology to complete a complete unlocking action. When the lock is unlocked next time, the eccentric shaft 401 rotates from the current side of the limit plate 302 to the other side, and the above operation is repeated.
