An elastic member is fixedly connected to the top end of the pressing plate, and an L-shaped plate is fixedly connected to the end of the elastic member away from the pressing plate.

[0007] Preferably, U-shaped plates corresponding to the positions of the L-shaped plates are fixedly connected to the four corners of the top surface of the circuit board. The U-shaped plates are slidably adapted to the L-shaped plates. A protruding portion is fixedly connected to the side of the circuit board located on the connecting plate, and a through groove is formed in the protruding portion.

[0010] Preferably, the spiral directions of the two sections of worm gears on the rotating shaft are opposite.

[0011] Preferably, a strip-shaped notch is formed in the top surface of the rotating rod.

[0012] Compared with the prior art, the present invention provides an intelligent lock drive controller that is convenient for installation, and has the following beneficial effects:

[0013] 1. In the present invention, two groups of locking assemblies are arranged on the side surface of the connecting plate facing the circuit board, and two groups of elastic telescopic assemblies are arranged on the side surface of the connecting plate facing away from the circuit board. When installing the circuit board of the intelligent lock drive controller, only need to first push the connecting plate to move towards the inside of the installation cavity, and then place the circuit board at the bottom of the installation groove of the outer side wall plate.

[0014] 2. In the present invention, a screwdriver is aligned with the strip-shaped notch at the top of the counter-rotating rod, thereby driving the rotating rod to rotate. Since the meshing of the two sections of worm gears and worm wheels enables the telescopic rods on the two sets of adjustable elastic telescopic components to rotate in different directions, when the two connecting blocks move to both sides, a greater force is required to push the connecting plate into the installation cavity. Moreover, the greater the inclination of the telescopic rod, the greater the compression length required for the telescopic rod, and the greater the compression length of the second spring, which means that a greater force is needed to compress the second spring. Under the combined action of the above two methods, the resistance to the inward movement of the connecting plate into the inner side of the installation cavity can be increased, preventing the L-shaped plate and the pressing plate from moving into the installation cavity under the action of external forces, canceling the fixed state of the circuit board, and making the circuit board easily removed.

[0015] 3. When the circuit board needs to be removed in the present invention, push the connecting plate inward. When the bottom end of the L-shaped plate disengages from the U-shaped plate and moves above the protruding part, the circuit board can be moved upward. The through slot is set in such a way that the protruding part will not block the L-shaped plate, enabling the circuit board to be smoothly removed from the outer side wall plate, which can save the time consumed in removing the circuit board.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an intelligent lock drive controller that is easy to install, including a circuit board 22 used for the controller and an outer side wall plate 1. The circuit board 22 is the circuit board inside the intelligent lock drive controller. An installation groove is opened at the top of the outer side wall plate 1, and the circuit board 22 is embedded in the installation groove. Installation cavities 2 communicating with the installation groove are symmetrically opened on both sides inside the outer side wall plate 1. A connection plate 3 is provided on one side of the installation cavity 2 located in the installation groove. Two locking components are provided on the side surface of the connection plate 3 facing the circuit board 22.

[0025] The locking component includes a sliding sleeve 4. The sliding sleeve 4 is fixed on the connection plate 3, the inside of the sliding sleeve 4 is slidably connected with a pressure plate 5, and a first spring 6 sleeved outside the pressure plate 5 is further provided inside the sliding sleeve 4. The two ends of the first spring 6 are respectively fixed to the inner side wall of the sliding sleeve 4 and the outer side wall of the pressure plate 5. The top end of the pressure plate 5 is fixedly connected with an elastic member 7. The elastic member 7 is made of soft steel, which not only has a certain structural strength but can also be bent under a certain pressure. When the pressure disappears, the elastic member 7 can return to its initial state. One end of the elastic member 7 far from the pressure plate 5 is fixedly connected with an L-shaped plate 8.

[0026] It should be noted that U-shaped plates 25 corresponding to the positions of the L-shaped plates 8 are fixedly connected to the four corners of the top surface of the circuit board 22. The U-shaped plates 25 are slidably adapted to the L-shaped plates 8. A protruding portion 23 is fixedly connected to the side of the circuit board 22 located on the connection plate 3, and a through groove 24 is opened on the protruding portion 23. The width of the through groove 24 is adapted to the width of the L-shaped plate 8. The width of the pressure plate 5 is greater than the width of the through groove 24. As Figure 2 、 3As shown, the connecting plate 3 has a tendency to move towards the circuit board 22 under the action of elastic force, so that the bottom of the L-shaped plate 8 is inserted into the U-shaped plate 25, and the corner of the L-shaped plate 8 will abut against the outer side of the U-shaped plate 25. The elastic member 7 deforms under the movement of the pressing plate 5 and generates elasticity. This elasticity will cause the pressing plate 5 to have a tendency to move downward, so that the pressing plate 5 abuts against the protruding portion 23 on the side of the circuit board 22, and under the elasticity of the elastic member 7, the bottom end of the pressing plate 5 will apply a downward pressure on the protruding portion 23 to lock and fix the circuit board 22, so that the circuit board 22 is limited to the bottom position of the installation groove.

[0027] It is worth mentioning that two sets of elastic telescopic components are arranged on the side of the connecting plate 3 facing away from the circuit board 22. When the circuit board 22 is placed at the bottom of the installation groove, the locking components on both sides of the circuit board 22 are clamped and pressed under the thrust of the elastic telescopic components to fix the circuit board 22 in the installation groove.

[0028] The elastic telescopic component includes a rotating block 9, the rotating block 9 is hinged to the side of the connecting plate 3, and one side of the rotating block 9 is fixedly connected with a telescopic rod 10. The end of the telescopic rod 10 away from the rotating block 9 is fixedly connected with a connecting block 11, and a second spring 12 is sleeved outside the telescopic rod 10. The two ends of the second spring 12 are respectively fixedly connected with the rotating block 9 and the connecting block 11. Under the elastic force of the second spring 12, the connecting plate 3 tends to move towards the circuit board 22, that is, when the circuit board 22 is placed at the bottom of the installation groove, the second springs 12 in the two installation cavities 2 on both sides are compressed and have a certain elastic deformation. The bottom end of the connecting block 11 is fixedly connected with an arc-shaped slider 13, and two arc-shaped chutes 14 are opened at the bottom of the installation cavity 2, and the arc-shaped slider 13 is slidably connected with the arc-shaped chute 14. A worm gear 15 is fixedly connected to the outside of the connecting block 11. One end of the rotating shaft 16 is fixedly connected with a first bevel gear 19.

[0029] It should be noted that tightening components for adjusting the inclination angle of the elastic telescopic components are provided on both sides of the outer side wall plate 1 to prevent the locking components from being easily unlocked. The tightening components include a rotating rod 21. The rotating rod 21 is rotatably connected to the outer side wall plate 1, and the bottom end of the rotating rod 21 extends into the installation cavity 2 and is fixedly connected to a second bevel gear 20. The first bevel gear 19 meshes with the second bevel gear 20. Two fixing members 18 are fixedly connected to both sides of the bottom of the installation cavity 2, and a rotating shaft 16 is rotatably connected between the two fixing members 18. Two sections of worm gears 17 are fixedly connected to both sides of the rotating shaft 16, and the two sections of worm gears 17 respectively mesh with the worm wheels 15 on two groups of elastic telescopic components. When the rotating rod 21 rotates, the rotating rod 21 drives the second bevel gear 20 to rotate. The second bevel gear 20 drives the rotating shaft 16 to rotate through meshing with the first bevel gear 19. The rotating shaft 16 drives the worm gear 17 to rotate. The meshing of the worm gear 17 and the worm wheel 15 enables the connecting block 11 to slide in the arc-shaped chute 14 through the arc-shaped slider 13. The connecting block 11 drives the telescopic rod 10 to rotate around the hinge joint of the rotating block 9 and the connecting plate 3.

[0030] Furthermore, the spiral directions of the two sections of worm gears 17 on the rotating shaft 16 are opposite. Thus, when the rotating shaft 16 rotates, the meshing of the two sections of worm gears 17 and the worm wheels 15 can cause the telescopic rods 10 on the two groups of adjusting elastic telescopic components to rotate in different directions, thereby changing the angle between them.

[0031] Furthermore, a strip-shaped notch is formed on the top surface of the rotating rod 21, which is convenient for aligning a screwdriver with the strip-shaped notch at the top of the rotating rod 21, thereby driving the rotating rod 21 to rotate.

[0032] The working principle and usage process of the present invention: The state shown in the figure is the state where the circuit board 22 has been fixed. The setting of the first spring 6 enables the pressure plate 5 to remain in a fixed position without external force, preventing the bottom end of the pressure plate 5 from automatically sliding downward in the sliding sleeve 4 without a supporting force.

[0033] When installing the circuit board 22 of the intelligent lock drive controller, first push the connecting plate 3 to move inward into the installation cavity 2. The connecting plate 3 drives the pressing plate 5, the elastic member 7, and the L-shaped plate 8 to move into the installation cavity 2 through the sliding sleeve 4. Then, place the circuit board 22 at the bottom of the installation groove of the outer side wall plate 1, and then release the connecting plate 3. The connecting plate 3 will move toward the circuit board 22 under the elastic action of the second spring 12. After that, the horizontal section at the bottom of the L-shaped plate 8 will be inserted into the U-shaped plate 25, and the corner of the L-shaped plate 8 will abut against the outer side surface of the U-shaped plate 25. At this time, the pressing plate 5 will continue to approach the circuit board 22. During this process, since the L-shaped plate 8 no longer moves, the elastic member 7 will deform under the movement of the pressing plate 5 and has a certain elasticity. This deformation will cause the pressing plate 5 to have a tendency to move downward. Finally, the pressing plate 5 will abut against the protruding portion 23 on the side of the circuit board 22, and under the elasticity of the elastic member 7, the bottom end of the pressing plate 5 will apply a downward pressure to the protruding portion 23 to lock and limit the circuit board 22. The state at this time is referred to Figure 2 and Figure 3 as shown.

[0034] To prevent the L-shaped plate 8 and the pressing plate 5 from moving into the installation cavity 2 under the action of external forces and canceling the fixed state of the circuit board 22. The resistance of the connecting plate 3 moving inward into the installation cavity 2 can be increased to prevent the above situation from occurring. The operation is as follows. Align the screwdriver with the strip-shaped notch at the top of the rotating rod 21 and rotate it. The rotating rod 21 will drive the second bevel gear 20 to rotate. The second bevel gear 20 will drive the rotating shaft 16 to rotate through meshing with the first bevel gear 19. The rotating shaft 16 drives the worm 17 to rotate. The meshing of the worm 17 and the worm gear 15 makes the connecting block 11 slide in the arc-shaped chute 14 through the arc-shaped slider 13. The connecting block 11 will drive the telescopic rod 10 to rotate around the hinge point of the rotating block 9 and the connecting plate 3. The spiral directions of the two worms 17 on the rotating shaft 16 are opposite. Therefore, when the rotating shaft 16 rotates, the meshing of the two worms 17 and the worm gears 15 can make the telescopic rods 10 on the two sets of adjustable elastic telescopic components rotate in different directions, that is, Figure 4 the two connecting blocks 11 in

[0035] After the above adjustment operation, when the connecting plate 3 is subjected to a force that pushes itself into the installation cavity 2, the angle between the direction of this force and the telescopic rod 10 becomes larger. According to the force analysis, the ratio of the thrust force received by the telescopic rod 10 to the force that pushes the connecting plate 3 into the installation cavity 2 is equal to the cosine value of this angle. Since the angle becomes larger and the cosine value becomes smaller, when the force that pushes the connecting plate 3 into the installation cavity 2 is the same, the larger the degree of this angle, the smaller the thrust force received by the telescopic rod 10. In summary, after the two connecting blocks 11 move to both sides, a greater force is required to push the connecting plate 3 into the installation cavity 2. Also, after the telescopic rod 10 rotates around the hinge joint between the rotating block 9 and the connecting plate 3 and becomes inclined, when the moving distance of the connecting plate 3 into the installation cavity 2 is certain, the more inclined the telescopic rod 10 is, the greater the compression length required for the telescopic rod 10, and the compression length of the second spring 12 becomes larger, which means a greater force is required to compress the second spring 12. Under the combined action of the above two, the resistance to the inward movement of the connecting plate 3 into the installation cavity 2 can be increased, preventing the L-shaped plate 8 and the pressing plate 5 from moving into the installation cavity 2 under the action of an external force, canceling the fixed state of the circuit board 22, and causing the circuit board 22 to come out.

[0036] When the circuit board 22 needs to be taken out, push the L-shaped plate 8 inward, push the connecting plate 3 through the pressing plate 5. When the pressing plate 5 enters the installation cavity 2 and the bottom end of the L-shaped plate 8 disengages from the U-shaped plate 25 and moves above the protruding portion 23, the circuit board 22 can be moved upward. The setting of the through groove 24 will exactly prevent the protruding portion 23 from blocking the L-shaped plate 8, and the circuit board 22 can be smoothly taken out from the outer side wall plate 1.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
