An intelligent lock controller with compensation

Abstract

The present invention discloses an intelligent lock controller with compensation, which includes a housing installed on a door body. A through groove is formed on the outer side surface of the housing, and an elastic member is arranged in the through groove. In the initial state, the elastic member is completely contracted in the through groove and blocks the through groove. In the present invention, the second magnet on the arc-shaped plate is located directly above the first magnet on the connecting plate. Since the first magnet and the second magnet are of the same size and the same magnetism, through the repulsive force between the first magnet and the second magnet, the connecting plate can have a tendency to move downward, and thus can be abutted against the top surface of the fixed block to prevent the connecting plate from moving upward under the action of other external forces and causing the elastic plate to deform. In the state where the elastic plate is located, it is similar to a plane without protruding structures, and people are not easily scratched or bruised by the door handle accidentally.

Due to the protruding structure of the door handle, people are easily scratched or bruised by the door handle accidentally, causing inconvenience. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent lock controller with compensation to solve the problem that the protruding structure of the controller door panel handle is easy to scratch and bruise as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An intelligent lock controller with compensation, including a housing installed on a door body. A through groove is opened on the outer side surface of the housing, and an elastic member is arranged in the through groove. The elastic member is completely contracted in the through groove in the initial state and blocks the through groove. A limiting component is arranged on the inner side of the bottom of the through groove, and a pushing and pulling component that pushes and pulls the bottom end of the elastic member to move up and down under the limitation of the limiting component. An electric control device for switching the up and down movement direction of the pushing and pulling component is also arranged on the inner side of the bottom of the through groove. When the intelligent lock is unlocked, the electric control device synchronously switches to control the pushing and pulling component to move upward, and the elastic member expands and bends from the through groove to a semi-circular shape.

[0006] Preferably, a display, a key, and a fingerprint recognition area are arranged on the outer side surface of the housing. A processor is installed inside the housing. The output ends of the key and the fingerprint recognition area are electrically connected to the input end of the processor, and the output end of the processor is electrically connected to the display and the electric control device.

[0007] Preferably, the elastic member includes an elastic plate. The elastic plate protrudes slightly outward in an arc shape in the initial state, and the top end of the elastic plate is hinged to the housing.

[0008] Preferably, the limiting component includes a fixed block. The fixed block is fixed inside the housing, and both sides of the top end of the fixed block are fixedly connected with sliding rods. The top ends of the two sliding rods are fixedly connected to the housing.

[0009] Preferably, the push-pull assembly includes a connecting plate, the bottom end of the elastic plate is hinged to the connecting plate, the connecting plate is slidably connected to the sliding rods on both sides, the top surface and bottom surfaces of the connecting plate are fixedly connected with first magnets, the magnetic poles of two first magnets located at one end of the same connecting plate are in opposite directions, an arc plate is provided on the outer side of both ends of the connecting plate, the inner side of the arc plate is fixedly connected with a second magnet corresponding to the position of the first magnet, the side of the arc plate facing away from the connecting plate is fixedly connected with a shaft rod, the shaft rod is rotatably connected to the shell, and the magnetic pole direction of the second magnet is adapted to the magnetic pole direction of the corresponding two first magnets.

[0010] Preferably, the electronic control device includes a dual-axis motor, which is fixedly installed inside a fixed block, and two output shafts of the dual-axis motor are fixedly connected with connecting shafts, and the ends of the connecting shafts are fixedly connected with second sprockets, and the shaft rod is fixedly connected with a first sprocket, and the first sprocket is connected to the second sprocket through a chain.

[0011] Preferably, the first magnet and the second magnet have the same size and the same magnetic properties.

[0012] Compared with the prior art, the present invention provides a smart lock controller with compensation, which has the following features:

[0013] Beneficial effects:

[0014] 1. The second magnet on the arc-shaped plate of the present invention is located directly above the first magnet on the connecting plate. Since the first magnet and the second magnet are of the same size and have the same magnetic properties, the repulsive force between the first magnet and the second magnet can make the connecting plate tend to move downward, and then can contact the top surface of the fixed block to prevent the connecting plate from moving upward under the action of other external forces (such as vibration when closing the door) and causing the elastic plate to deform. The elastic plate is in a state similar to a plane without a protruding structure, so people are not likely to be scratched or bumped by the door handle due to accidents.

[0015] 2. When the smart lock body of the present invention is unlocked, the dual-axis motor will be started under the control of the processor, causing the second magnet to rotate 180 degrees and be located directly below the first magnet on both sides of the bottom surface of the connecting plate. Due to the same magnetic poles, repulsive force is generated to move the connecting plate upward until the bent shape of the elastic plate resembles a semicircle. At this time, the user can hold the semicircular elastic plate and pull the door to open or close.

[0016] 3. When the door body of the present invention is closed, the externally connected intelligent lock body is relocked. At this time, the processor will control the dual-axis motor to rotate in the reverse direction. During the process of the arc-shaped plate driving the second magnet to rotate, when the second magnet no longer faces the first magnets on both sides of the bottom end of the connecting plate, the connecting plate will move downward along the sliding rod under its own gravity and the elasticity of the elastic plate, and finally contact the top end of the fixed block. The arc-shaped plate continues to drive the second magnet to rotate back to the initial position, realizing the rapid retraction of the elastic plate.

[0017] 4. In the case of long-term use of the elastic plate, the elastic plate is prone to large arc deformation, which is not conducive to restoring the initial state. The second magnet and the first magnet have the function of compensating the acting force, which is more conducive to the elastic plate 9 restoring the initial state.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: an intelligent lock controller with compensation, including a housing 1. The housing 1 is installed on the door body. A display 2, a button 3, and a fingerprint recognition area 4 are arranged on the outer side surface of the housing 1, and a processor 5 is installed inside the housing 1. The output ends of the button 3 and the fingerprint recognition area 4 are electrically connected to the input end of the processor 5, and the output end of the processor 5 is electrically connected to the display 2. Digital passwords can be input through the button 3, fingerprints can be input through the fingerprint recognition area 4, whether the password is correct can be displayed on the display 2, and the input information can be processed and analyzed by the processor 5. When the fingerprint or the password is correct, the processor 5 issues an unlocking command to the external intelligent lock body, and the external intelligent lock body realizes unlocking, thereby being able to open the door body. The external intelligent lock body is installed on the door body and is electrically connected to the processor 5.

[0028] It should be noted that a through groove is provided on the outer side surface of the housing 1, and an elastic member is arranged in the through groove. The elastic member is completely contracted in the through groove and blocks the through groove in the initial state. The elastic member includes an elastic plate 9, and the elastic plate 9 is slightly convex outward and arc-shaped in the initial state. The top end of the elastic plate 9 is hinged to the housing 1. The elastic plate 9 is made of a steel sheet material with a certain elasticity, which can not only ensure the structural strength but also bend and deform when subjected to pressure, and a soft rubber sleeve is covered on its outside to improve comfort and avoid hand scratches.

[0029] It is worth mentioning that a limiting component and a pushing and pulling component for pushing and pulling the bottom end of the elastic member to move up and down in the direction limited by the limiting component are arranged on the inner side of the bottom of the through groove. The limiting component includes a fixing block 6, the fixing block 6 is fixed inside the housing 1, and both sides of the top end of the fixing block 6 are fixedly connected with sliding rods 7, and the top ends of the two sliding rods 7 are fixedly connected to the housing 1.

[0030] It should be noted that the push-pull assembly includes a connecting plate 8. The bottom end of the elastic plate 9 is hinged to the connecting plate 8, and the connecting plate 8 is slidably connected to the sliding rods 7 on both sides, and the first magnets 10 are fixedly connected to both sides of the top surface and the bottom surface of the connecting plate 8. The magnetic poles of the two first magnets 1 located at one end of the same connecting plate 8 are in opposite directions. An arc plate 11 is provided on the outer side of both ends of the connecting plate 8. A second magnet 12 corresponding to the position of the first magnet 10 is fixedly connected to the inner side of the arc plate 11. A shaft is fixedly connected to the side of the arc plate 11 facing away from the connecting plate 8. The shaft is rotatably connected to the housing 1. The magnetic pole direction of the second magnet 12 matches the magnetic pole direction of the corresponding two first magnets 10.

[0031] like Figure 2 , 3 In the state shown, the second magnet 12 on the arc plate 11 is located directly above the first magnet 10 on both sides of the top surface of the connecting plate 8. Since the first magnet 10 and the second magnet 12 on both sides of the top surface of the connecting plate 8 are the same size and the magnetic poles point in opposite directions. Through the repulsive force of the first magnet 10 and the second magnet 12, the connecting plate 8 can have a tendency to move downward, and then it can contact the top surface of the fixed block 6. In addition, when the second magnet 12 rotates to the bottom of the first magnet 10 on both sides of the bottom surface of the connecting plate 8, since the first magnet 10 and the second magnet 12 on both sides of the bottom surface of the connecting plate 8 are the same size and the magnetic poles point in opposite directions. Through the repulsive force of the first magnet 10 and the second magnet 12, the connecting plate 8 can have a tendency to move upward, and then the upward movement of the connecting plate 8 can push the elastic plate 9 to deform.

[0032] It should be added that an electric control device for switching the movement direction of the push-pull assembly is also provided on the inner side of the bottom of the through groove. The output end of the processor 5 is electrically connected to the electric control device. The electric control device includes a dual-axis motor 16, which is fixedly mounted inside the fixed block 6. A connecting shaft 17 is fixedly connected to both output shafts of the dual-axis motor 16. A second sprocket 15 is fixedly connected to the end of the connecting shaft 17, and a first sprocket 13 is fixedly connected to the shaft rod. The first sprocket 13 is transmission-connected to the second sprocket 15 via a chain 14.

[0033] In summary, when the smart lock is unlocked, the electronic control device synchronously switches to control the push-pull assembly to move upward, thereby causing the elastic part to expand and bend from the through groove to a semicircular shape.

[0034] Working principle and usage process of the present invention: All the states shown in the figure are the states after the device is locked. Among them: There are four first magnets 10, and the four first magnets 10 are respectively embedded on both sides of the top surface and both sides of the bottom surface of the connecting plate 8, and the two first magnets 10 located on both sides of the top surface of the connecting plate 8 both have the N pole facing upwards. When the second magnet 12 is directly above the first magnets 10 on both sides of the top surface of the connecting plate 8, the N pole of the second magnet 12 faces downwards. Due to the same magnetic poles, a repulsive force is generated, which can make the connecting plate 8 tend to move downwards, thereby maintaining the state of the elastic plate 9 at this time to prevent the connecting plate 8 from moving upwards under the action of other external forces (such as the vibration when closing the door) and deforming the elastic plate 9. The bottom surface of the connecting plate 8 is in contact with the top surface of the fixed block 6; the elastic plate 9 is in a state with a certain arc, and the degree of bending is small and its own elasticity is small. Refer to Figure 6 , the convex part of the arc of the elastic plate 9 faces the outside of the housing 1.

[0035] When the user performs fingerprint recognition or enters a password through the button 3, the processor 5 processes the information transmitted from the button 3 or the fingerprint recognition area 4. When the fingerprint is correct or the password is correct, the processor 5 issues an unlocking command to the external lock body, and the external intelligent lock body realizes unlocking. At the same time, the biaxial motor 16 will be started under the control of the processor 5. The biaxial motor 16 drives two connecting shafts 17 to rotate through the motor shafts. The connecting shafts 17 drive the second sprocket 15 to rotate. The second sprocket 15 drives the first sprocket 13 to rotate through the chain 14, and the first sprocket 13 drives the arc-shaped plate 11 and the second magnet 12 to rotate. After the second magnet 12 rotates 180 degrees, the biaxial motor 16 automatically stops. At this time, the second magnet 12 is directly below the first magnets 10 on both sides of the bottom surface of the connecting plate 8. The two first magnets 10 located on both sides of the bottom surface of the connecting plate 8 both have the N pole facing downwards. When the second magnet 12 is directly below the first magnets 10 on both sides of the bottom surface of the connecting plate 8, the N pole of the second magnet 12 faces upwards. Due to the same magnetic poles of the first magnet 10 and the second magnet 12, a repulsive force is generated, which can make the connecting plate 8 move upwards. During the upward movement of the connecting plate 8, the elastic plate 9 will gradually become a semi-circular handle. Finally, the connecting plate 8 moves to the top of the sliding rod 7 and is blocked by the housing 1 and cannot move anymore. At this time, the shape of the elastic plate 9 is similar to a semi-circle. At this time, the user can hold the semi-circular elastic plate 9 and pull the door body to open or close.

[0036] When the door body is closed, the externally connected intelligent lock body is relocked. At this time, the processor 5 will control the double-axis motor 16 to rotate in the reverse direction. During the process of the arc-shaped plate 11 driving the second magnet 12 to rotate, when the second magnet 12 is no longer facing the first magnets 10 on both sides of the bottom end of the connecting plate 8, the connecting plate 8 will move downward along the sliding rod 7 under its own gravity and the elasticity of the elastic plate 9, and finally contact the top end of the fixed block 6. The arc-shaped plate 11 continues to drive the second magnet 12 to rotate and return to the initial position, and then the double-axis motor 16 automatically stops, enabling the connecting plate 8 and the elastic plate 9 to return to the initial state. Since the downward movement speed of the connecting plate 8 is much greater than the rotation speed of the second magnet 12, there will be no movement interference between the two.

[0037] After long-term use, when the elastic plate 9 is subjected to the pulling force of the hand, it tends to become a shape with a larger arc, and the elastic plate 9 extends beyond the range of the housing 1. In this case, the second magnet 12 is directly above the first magnets 10 on both sides of the top surface of the connecting plate 8. Since the opposite magnetic poles of the first magnet 10 and the second magnet 12 are the same, the repulsive force can cause the connecting plate 8 to have a tendency to move downward, thereby maintaining the state of the elastic plate 9 at this time, which has a good effect on keeping the elastic plate 9 in the initial state. Furthermore, the second magnet 12 and the first magnet 10 have the function of compensating for the deformation of the elastic plate 9 to restore to the initial state.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art 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.
