Detailed Implementation

[0019] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1 , 2As shown, a mechanical and electronic dual-control lock body includes a lock body 1, which contains a locking pin assembly cavity 101, a mechanical lock cylinder 2, and a drive assembly 3. The locking pin assembly cavity 101 contains a locking pin assembly 4, which includes a locking pin 401 and a return spring 402 sleeved on the locking pin 401. One end of the locking pin assembly cavity 101 has a retraction space, within which a locking post 5 is provided, preventing the locking pin assembly 4 from retracting. Below the retraction space is a communicating movable cavity 102, within which a movable block 6 is provided, which is connected to the locking post 5.

[0021] The drive assembly 3 is located below the movable cavity 102. The drive assembly 3 drives the movable block 6 to move up and down within the movable cavity 102 via an elastic element, thereby allowing the movable block 6 to move the locking pin 5 away from or into the retractable space. The mechanical lock cylinder 2 is connected to a connecting piece 7, which extends into the movable cavity 102 and connects to the locking pin 5. The mechanical lock cylinder 2 can drive the connecting piece 7 to move up and down through rotational motion or axial movement.

[0022] Specifically, the drive assembly 3 includes a motor 301 and a motor shaft 302 connected to the motor 301. A horizontal bolt 303 is provided on the motor shaft 302, and the elastic element is a spring 8. The spring 8 is sleeved on the motor shaft 302, the horizontal bolt 303 is inserted through the middle of the spring 8, the movable block 6 is sleeved on the motor shaft 302 and the spring 8, at least one end of the spring 8 is fixed to the movable block 6, and the locking pin 5 is sleeved on the end of the motor shaft 302.

[0023] One end of the connecting piece 7 is provided with a U-shaped groove, which engages with the mechanical lock cylinder 2. The other end of the connecting piece 7 is provided with a through hole, and the locking pin 5 is located in the through hole. The bottom of the locking pin 5 is provided with a radial protrusion 501, and the bottom of the locking pin 5 is provided with a thrust spring 9. One end of the thrust spring 9 abuts against the bottom surface of the connecting piece 7, and the other end abuts against the protrusion 501.

[0024] The working principle of the mechanical and electronic dual-control lock body 1 of this utility model is as follows:

[0025] 1. Reference Figure 1 In the locked state, the locking pin 5 is located in the contraction space and presses against the locking pin 401, preventing the locking pin 401 from moving backward, thus forming a lock.

[0026] 2. Electronic switch lock: Reference Figure 2 When unlocking, motor 301 drives motor shaft 302 to rotate, and bolt 303 rotates within the pitch of spring 8, causing spring 8 to move downward. Then spring 8 drives movable block 6 to move downward. After movable block 6 moves downward, locking pin 5 exits from the retractable space under the action of thrust spring 9, completing the unlocking process. When locking, motor 301 rotates in the opposite direction, bolt 303 drives spring 8 to move upward, and spring 8 drives movable block 6 to move upward. After movable block 6 moves upward, it pushes locking pin 5 into the retractable space, completing the locking process.

[0027] 3. Mechanical switch lock: (See reference) Figure 3 When unlocking, the mechanical lock cylinder 2 drives the locking pin 5 to move down through the connecting piece 7. At this time, the spring 8 is compressed, the movable block moves down, and the locking pin 5 exits the retracted space, completing the unlocking. When locking, the mechanical lock cylinder 2 drives the locking pin 5 to move up, and the locking pin 5 returns to the retracted space to press against the lock pin 401.

[0028] like Figure 4 As shown, this embodiment also provides a lock, including a lock beam 10, one end of which is rotatably connected to the lock body 1, and the other end is engaged with the lock pin assembly 4.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
