Description

Technical Field

[0001] The present invention belongs to the technical field of electronic locks, and particularly relates to an intelligent bedside table electronic lock. Background Art

[0002] An intelligent electronic lock, also known as an electronic door lock, is a lock that uses electronic technology to control the opening and closing of the lock. Compared with traditional mechanical locks, intelligent electronic locks have higher security, programmability, and convenience. With the improvement of the technical level of intelligent electronic locks, the use of intelligent electronic locks in daily life is becoming more and more widespread. As a commonly used piece of furniture, bedside tables generally store relatively private items. With the increasing emphasis on privacy by people, the application of intelligent electronic locks on bedside tables is becoming more and more widespread. However, when the existing intelligent electronic locks are used on bedside tables, the following technical problems still exist:

[0003] 1. When the existing intelligent electronic locks are in use, the locking and unlocking actions are generally completed by controlling the telescopic movement of the lock tongue through a motor. However, due to the difficulty of accurately starting and stopping the driving motor, when the existing intelligent electronic locks are working, there will be a large error in the telescopic stroke of the lock tongue each time, resulting in an excessive stroke of the lock tongue, which may cause the lock tongue to collide with the lock body or the lock hole, and even damage the lock tongue, the lock body, and the lock hole.

[0004] 2. When the existing intelligent electronic locks are in use, in order to allow the lock tongue to smoothly extend into the lock hole, there is generally a large gap between the lock hole and the lock tongue. This makes the cabinet door not close tightly after the intelligent electronic lock is locked, the cabinet door is prone to shaking, and the internal items are prone to falling out, reducing the storage function of the bedside table.

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand 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 improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] As Figures 1 - 8 shown, an intelligent bedside table electronic lock includes: a lock body 1, a lock cap 2, a lock tongue 3, and a locking pin ⑤; the lock body 1 is arranged on the cabinet door 18; the lock cap 2 is arranged in the cabinet body 17, and a lock hole is provided in the lock cap 2; the lock tongue 3 is arranged on the lock body 1 and can move relative to the lock body 1 and extend into the lock hole; the locking pin ⑤ is eccentrically rotatably connected to one end of the lock tongue 3; when the lock tongue 3 extends into the lock hole, the locking pin ⑤ rotates relative to the lock tongue 3 to a position where it contacts the inner wall of the lock hole; when the lock tongue 3 withdraws from the lock hole, the locking pin ⑤ first rotates back to a position away from the inner wall of the lock hole, and then the lock tongue 3 withdraws from the lock hole.

[0030] During specific operation, when the lock tongue 3 extends into the lock hole, the locking pin ⑤ rotates relative to the lock tongue 3 to a position where it contacts the inner wall of the lock hole, so as to fill the gap between the lock tongue 3 and the inner wall of the lock hole through the locking pin ⑤, making the cabinet door fit more tightly with the cabinet body after being closed in place, the cabinet door cannot shake, and the items in the cabinet will not fall out.

[0031] As Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 shown, the intelligent bedside table electronic lock further includes a telescopic block 4; the telescopic block 4 is slidably connected to the lock tongue 3, and one end of the telescopic block 4 abuts against the locking pin ⑤; when the telescopic block 4 slides to the right relative to the lock tongue 3, the telescopic block 4 pushes the locking pin ⑤ to rotate towards the direction close to the inner wall of the lock hole.

[0032] As Figures 3 - 8 shown, the intelligent bedside table electronic lock further includes a worm gear 7, a worm 8, a connecting rod 9, a limiting plate 10, and a positioning pin 12; the worm 8 is rotatably connected horizontally in the lock body 1; the worm gear 7 is rotatably connected to the lock tongue 3, and the worm gear 7 meshes with the worm 8; one end of the connecting rod 9 is eccentrically hinged to the worm gear 7, and the other end is hinged to the telescopic block 4; the limiting plate 10 is fixedly connected horizontally in the lock body 1; the positioning pin 12 is fixedly arranged on the lock tongue 3.

[0033] As Figures 3 - 8As shown, when the upper end of the connecting rod 9 contacts the positioning pin 12 and the lower end of the connecting rod 9 contacts the upper end of the limit plate 10, the worm gear 7 cannot rotate. When the worm 8 rotates, it can drive the locking tongue 3 to move horizontally along with the worm gear 7. When the locking tongue 3 moves to the point where the lower end of the connecting rod 9 disengages from the upper end of the limit plate 10, the worm gear 7 can rotate, and the worm gear 7 drives the connecting rod 9 to drive the telescopic block 4 to slide relative to the locking tongue 3.

[0034] During specific operation, through the cooperation of the worm gear 7, the worm 8, the connecting rod 9, the limit plate 10 and the positioning pin 12, the separate control of the locking tongue 3 and the telescopic block 4 can be achieved by rotating the worm 8. The operation is convenient and the structure is simple and ingenious.

[0035] As Figure 3 、 Figure 6 shown, the intelligent bedside table electronic lock further includes a limit rope 13, a roller 14 and a spring 15. The roller 14 is rotatably connected to the lock body 1. The limit rope 13 is wound around the roller 14. One end of the limit rope 13 is fixedly connected to the roller 14, and the other end is fixedly connected to the locking tongue 3. The spring 15 is located inside the roller 14 and is used to drive the roller to rotate in the direction of winding the limit rope 13 onto the roller 14.

[0036] As Figure 3 、 Figure 6 shown, when the limit rope 13 is fully pulled out, the locking tongue 3 cannot continue to move to the right, and the locking tongue 3 does not collide with either the lock body 1 or the lock cap 2.

[0037] During specific operation, by setting the locking tongue 3, the telescopic block 4 and the limit rope 13, when the locking tongue 3 extends to the proper position, the position of the locking tongue 3 is restricted by the limit rope 13, so that the movement of the locking tongue 3 will not collide with the lock body 1 or the lock cap 2, and the locking tongue 3, the lock body 1 and the lock cap 2 will not be damaged. At the same time, when the locking tongue 3 extends to the proper position, the motor 11 is controlled to continue rotating to control the telescopic block 4 to continue to extend, and the locking pin 5 is pushed to rotate, so that the telescopic stroke of the locking tongue 3 is not controlled by the operation of the motor 11, ensuring the service life of the intelligent electronic lock.

[0038] As Figure 4 、 Figure 7 shown, the intelligent bedside table electronic lock further includes a torsion spring 6. The torsion spring 6 is arranged inside the locking pin 5 and is used to drive the locking pin 5 to rotate towards the telescopic block 4.

[0039] As Figure 3 、 Figure 4 、 Figure 6 、[[ID=?]] Figure 7 shown, the intelligent bedside table electronic lock further includes a locking tongue spring 16. The locking tongue spring 16 is located inside the lock body 1 and is used to drive the locking tongue 3 to move towards the direction of extending into the lock cap 2.

[0040] As Figures 3 - 7As shown, the intelligent bedside table electronic lock further includes a motor 11, which is fixedly connected inside the lock body 1, and the output shaft of the motor 11 is fixedly connected to the worm 8.

[0041] As Figure 1 , Figure 2 shown, the intelligent bedside table electronic lock further includes a touch screen 19, which is arranged on the cabinet door 18. The touch screen 19 can input an unlocking password. A sensor is arranged inside the touch screen 19 to detect whether the cabinet door 18 is closed in place. A control circuit is also arranged inside the touch screen 19 to control the motor 11 to work.

[0042] The working principle of the present invention is as follows:

[0043] As Figure 3 shown is the internal structure of the present invention. The lock body 1 is fixedly arranged inside the cabinet door, and the lock cap 2 is arranged inside the cabinet. When the cabinet door is closed in place, the sensor arranged inside the touch screen detects that the cabinet door is closed in place, and then controls the motor 11 to rotate forward, driving the worm 8 to rotate forward accordingly. At this time, the lower side of the connecting rod 9 is in close contact with the limiting plate 10, and the upper side touches the positioning pin 12. One end of the connecting rod 9 is eccentrically hinged to the worm gear 7, and the other end is hinged to the telescopic block 4, so that the worm gear 7 cannot rotate relative to the lock tongue 3. Since the worm 8 meshes with the worm gear 7, the worm gear 7 is driven to move to the right, and the lock tongue 3 and the telescopic block 4 are driven to move to the right together, so that the lock tongue 3 and the telescopic block 4 extend into the lock hole. Since the limiting rope 13 is wound around the roller shaft 14, one end of the limiting rope 13 is fixedly connected to the roller shaft 14, and the other end is fixedly connected to the lock tongue 3. Therefore, as the lock tongue 3 moves to the right, the roller shaft 14 is driven to rotate against the spring 15 through the limiting rope 13, and at the same time the lock tongue spring 16 elongates; when the limiting rope 13 is completely released, the limiting rope 13 pulls the lock tongue 3 to stop, so that when the lock tongue 3 moves to the right in place, it will not collide with the lock body 1 and the lock cap 2, ensuring the service life of the lock tongue 3, the lock body 1 and the lock cap 2. At this time, the connecting rod 9 just separates from the limiting plate 10, and the connecting rod 9 can swing downward. Since the worm gear 7 meshes with the worm 8, the worm 8 continues to rotate forward, driving the worm gear 7 to rotate counterclockwise ( Figure 3 in), so that the connecting rod 9 moves away from the positioning pin 12, and drives the telescopic block 4 to continue to move to the right through the connecting rod 9. Since the locking pin 5 is rotatably connected to the lock tongue 3, the telescopic block 4 is used to push the locking pin 5 to rotate against the torsion spring 6. As the locking pin 5 flips, when the locking pin 5 is in close contact with the inner wall of the lock hole, the locking pin 5 fills the gap between the lock tongue 3 and the lock hole, thereby driving the cabinet door to be more tightly attached to the cabinet body, avoiding the shaking of the cabinet door, and preventing the items inside the cabinet from falling. When the locking pin 5 can no longer rotate outward, the worm 8 cannot continue to rotate forward, causing the motor 11 to be blocked, the current to increase, and the motor 11 to stop, completing the locking.

[0044] When unlocking is required, first, the correct password needs to be entered on the touch screen, and then the motor 11 is controlled by the internal circuit of the touch screen to drive the worm 8 to reverse. Due to the action of the lock tongue spring 16, the lock tongue 3 remains stationary in the lock hole temporarily. The worm 8 drives the worm wheel 7 to rotate clockwise ( Figure 6 as shown in Figure 6 ), and then drives the connecting rod 9 to drive the telescopic block 4 to move leftward. The locking pin 5 rotates under the action of the torsion spring 6. As the worm wheel 7 rotates clockwise, when the connecting rod 9 returns to the horizontal position again, the upper side of the connecting rod 9 touches the positioning pin 12, making the worm wheel 7 unable to continue rotating. At this time, the locking pin 5 rotates and resets under the action of the torsion spring 6, controlling the worm 8 to continue to reverse, driving the worm wheel 7 to move leftward, and then driving the lock tongue 3 to overcome the lock tongue spring 16 and move leftward, causing the connecting rod 9 to move accordingly. The lower side of the connecting rod 9 is in close contact with the limiting plate 10. As the lock tongue 3 moves leftward, it drives the roller shaft 14 to rotate under the action of the spring 15, and winds the limiting rope 13 on the roller shaft 14. When the lock tongue 3 returns to the initial position, the lock tongue 3, the telescopic block 4, and the locking pin 5 completely withdraw from the lock hole, and the motor 11 is controlled to stop, completing the unlocking action. Since the lock tongue 3 does not collide with the lock body 1 and the lock cap 2 when moving leftward, the service lives of the lock tongue 3, the lock body 1, and the lock cap 2 are guaranteed.

[0045] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
