DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 A password lock mechanism in this embodiment includes a lock body 1, a locking component 2 for improving impact resistance is provided between the front and rear inner walls of the lock body 1, and a control component 3 for combined opening and closing is provided on the upper and lower sides of the locking component 2.

[0025] See also Figures 2 to 3 In order to improve the impact resistance, the locking assembly 2 in this embodiment includes two protective slides 21 fixed between the front and rear inner walls of the lock body 1, and a lock tongue 22 is slidably connected between the inner walls on the opposite sides of the two protective slides 21. When locking is required, the user operates the control assembly 3 to make the lock tongue 22 extend out of the protective slide 21 until the lock tongue 22 is inserted into the lock box to complete the locking action. An anti-impact plate 23 is fixed on the front of the lock tongue 22, and a number of tensile vertical ribs 24 are vertically fixed on the front of the anti-impact plate 23. A reinforcing rib 25 fixed to the several tensile vertical ribs 24 is fixed on the front of the anti-impact plate 23. When there is no external operation, the locking assembly 2 keeps the lock tongue 22 in the position in the protective slide 21. The anti-impact plate 23, the tensile vertical ribs 24 and the reinforcing rib 25 of the lock tongue 22 provide additional strength and impact protection for the lock tongue 22.

[0026] In this embodiment, the cross-sectional shape of the protective slide 21 is U-shaped, the length of the lock tongue 22 is equal to the length of the protective slide 21, a controller and a battery are respectively provided inside the lock body 1, a lock opening is opened on the left side of the lock body 1, and the left ends of the two protective slides 21 are both located between the front and rear inner walls of the lock opening, and a number of tensile vertical ribs 24 are evenly distributed along the length direction of the anti-impact plate 23. In the locked state, if there is an external impact attempting to destroy the lock tongue 22, the anti-impact plate 23 and the tensile vertical ribs 24 and the reinforcing ribs 25 will absorb and disperse the impact force to protect the lock tongue 22 from damage. The length of the reinforcing rib 25 is equal to the length of the lock tongue 22. When the user enters the correct password and is verified, the control component 3 will drive the lock tongue 22 to retract into the protective slide 21, thereby unlocking the lock.

[0027] See also Figure 4In order to control the opening and closing in combination, the control component 3 in this embodiment includes connecting blocks 31 fixed on the upper and lower sides of the lock tongue 22 respectively, and tooth plates 32 are fixed on the opposite sides of the two connecting blocks 31. A driving motor 33 is fixed to the back wall of the inner cavity of the lock body 1 and above the upper tooth plate 32. A transmission shaft 34 is fixed to the outer side of the output shaft of the driving motor 33, and a first gear 35 meshing with the upper tooth plate 32 is fixed to the outer side of the transmission shaft 34. When the user enters the password, the lock body 1 receives the input password and compares it with the preset correct password for verification. If the password is correct, the controller sends a signal to start the driving motor 33, driving The motor 33 rotates through the transmission shaft 34, driving the first gear 35, and the first gear 35 meshes with the upper tooth plate 32. The rotational power is transmitted to the upper tooth plate 32, causing it to move horizontally. A lock core 36 is rotatably connected between the front and rear inner walls of the lock body 1, and a second gear 37 meshing with the lower tooth plate 32 is fixed to the outside of the lock core 36. When the lock body 1 loses power supply, the user can insert the matching key into the lock core 36. The rotation of the key drives the lock core 36 to rotate, thereby rotating the second gear 37, and the second gear 37 meshes with the lower tooth plate 32. The rotational power controls the extension and retraction of the lock tongue 22 to achieve emergency unlocking.

[0028] In this embodiment, sliding openings 38 are provided on the inner walls on the opposite sides of the two protective slides 21, and the two connecting blocks 31 are slidably connected between the front and rear inner walls of the two sliding openings 38 respectively. The movement of the upper tooth plate 32 drives the connecting block 31 to move horizontally in the sliding opening 38, and the movement of the connecting block 31 drives the lock tongue 22 to be retracted into the lock body 1 to achieve unlocking. The length of the tooth plate 32 is equal to the length of the connecting block 31, and the end of the transmission shaft 34 away from the drive motor 33 is rotatably connected to the main wall of the inner cavity of the lock body 1 through a bearing.

[0029] It should be noted that when the user needs to lock, the control component 3 is operated in reverse, and the controller sends a signal to make the drive motor 33 rotate in the opposite direction or stop rotating. The lock tongue 22 extends outward under the action of the tooth plate 32 and is inserted into the matching lock box to achieve locking.

[0030] The present invention also proposes a lock, which includes a password lock mechanism as described in any of the above embodiments. Since the specific structures of the locking component 2 and the control component 3 in the lock refer to the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0031] The working principle of the above embodiment is:

[0032] (1) When there is no external operation, the locking component 2 keeps the lock tongue 22 in position in the protective slide 21. The anti-impact plate 23, tensile ribs 24 and reinforcing ribs 25 of the lock tongue 22 provide additional strength and anti-impact protection for the lock tongue 22. When locking is required, the user operates the control component 3 to extend the lock tongue 22 out of the protective slide 21 until the lock tongue 22 is inserted into the lock box, completing the locking action. In the locked state, if there is an external impact that attempts to destroy the lock tongue 22, the anti-impact plate 23, tensile ribs 24 and reinforcing ribs 25 will absorb and disperse the impact force to protect the lock tongue 22 from damage. When the user enters the correct password and is verified, the control component 3 will drive the lock tongue 22 to retract into the protective slide 21, thereby unlocking the door.

[0033] (2) The user enters a password, the lock body 1 receives the entered password, and compares it with the preset correct password for verification. If the password is correct, the controller sends a signal to start the drive motor 33. The drive motor 33 rotates through the transmission shaft 34, driving the first gear 35. The first gear 35 engages with the upper side gear plate 32, and the rotational power is transmitted to the upper side gear plate 32, causing it to move horizontally. The movement of the upper side gear plate 32 drives the connecting block 31 to move horizontally in the sliding opening 38. The movement of the connecting block 31 then drives the lock tongue 22 to retract into the lock body 1, realizing To unlock, when the user needs to lock, the control component 3 is used to perform a reverse operation. The controller sends a signal to make the drive motor 33 rotate in the opposite direction or stop rotating. The lock tongue 22 extends outward under the action of the tooth plate 32 and is inserted into the matching lock box to achieve locking. When the lock body 1 loses power supply, the user can insert the matching key into the lock cylinder 36. The rotation of the key drives the lock cylinder 36 to rotate, and then the second gear 37 rotates. The second gear 37 engages with the lower tooth plate 32, and controls the extension and retraction of the lock tongue 22 through its rotational power to achieve emergency unlocking.
