Description

Technical Field

[0001] The present invention belongs to the technical field of opening and closing locks, and in particular relates to a connecting mechanism for an opening and closing lock robot and the opening and closing lock robot. Background Art

[0002] Currently, anti-theft locks are widely used on doors in various settings due to their high security. A variety of anti-theft locks are available on the market, including conventional, combination, and fingerprint locks. Combination and fingerprint locks offer automatic locking and unlocking, while conventional locks require manual key unlocking and locking. For newly renovated homes, simply installing combination or fingerprint locks offers automatic locking and unlocking. However, for doors already equipped with conventional locks, the only way to restore automatic locking and unlocking is to replace the entire lock or door. However, due to the varying shapes and sizes of lock bodies, the new and old lock bodies often do not match, requiring on-site drilling and slotting in the door. This replacement process is complex, labor-intensive, and expensive.

[0003] Therefore, a lock opening and closing robot has emerged. The lock opening and closing robot is a device that is installed on the anti-theft lock of the door and automatically unlocks and locks the anti-theft lock. There is no need to replace the entire anti-theft lock or the entire door. The lock opening and closing robot only needs to be installed on the conventional anti-theft lock to enable the anti-theft lock to have the functions of automatic unlocking and automatic locking. It is easy to install, has a small workload, and is low in cost. The existing lock opening and closing robot includes a shell body, a connector, and a motor. The shell body is installed on the anti-theft lock or the door, and the connector is rotatably connected to the shell body, and the connector is connected to the unlocking and locking knob of the anti-theft lock. The motor is installed in the shell body and drives the connector to rotate forward or reverse, thereby driving the unlocking and locking knob of the anti-theft lock to rotate forward or reverse, to achieve the functions of automatic unlocking and automatic locking of the anti-theft lock.

[0004] The connector of existing lock and unlock robots features two clamping blocks and two springs. The two springs elastically push the two clamping blocks toward each other, and the rebound force of the two springs clamps the lock's lock knob between the two clamping blocks. To ensure the knob is securely held between the two clamping blocks, the spring force is typically set high. Consequently, the high spring rebound force acting on the clamping blocks during installation makes it difficult for some users to manually pry the two clamping blocks apart, hindering installation. Summary of the Invention

The output end of the transmission mechanism is connected to the connecting mechanism. A clutch mechanism is installed between the input end of the transmission mechanism and the output end of the driving mechanism. When the driving mechanism operates, the clutch mechanism makes the input end of the transmission mechanism and the output end of the driving mechanism in transmission connection. When the driving mechanism stops, the clutch mechanism makes the input end of the transmission mechanism and the output end of the driving mechanism disconnected from transmission connection.

[0016] Compared with the prior art, at least one of the above one or more technical solutions in the connecting mechanism for an unlocking and locking robot provided by the embodiments of the present invention has the following technical effects:

[0017] During installation, an external force (hand pressing force) presses the two pressing portions to drive the front ends of the two elastic clamping portions to move away from each other, so that the clamping position is in an open state. Then, the unlocking and locking knob of the anti-theft lock is inserted into the clamping position. After removing the external force, the front ends of the two elastic clamping portions approach each other under the action of their own resilience, and the unlocking and locking knob of the anti-theft lock is fixedly clamped between the two elastic clamping portions.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0040] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0041] In one embodiment of the present invention, referring to Figure 1 [[ID=......]]and Figure 10 , a connection mechanism 200 for an opening and closing robot is provided, which includes a connection main part 210, a clamping part 220 mounted on the connection main part 210, and two pressing parts 230. The connection main part 210 is rotatably mounted on the housing main body 100 of the opening and closing robot.

[0042] Referring to Figure 1 [[ID=......]]and Figure 10 , the clamping part 220 is symmetrically provided with two elastic clamping parts 221. The two elastic clamping parts 221 are distributed in a "V" shape. Specifically, the elastic clamping part 221 is in a plate shape. The front ends of the two elastic clamping parts 221 approach each other under the action of their own resilience, and a clamping position 222 is formed between the two elastic clamping parts 221.

[0043] Referring to Figure 1 [[ID=......]]and Figure 10 It seems there are some incomplete "and" parts in your original text (marked with "......" in the translation). You may want to check and correct the original for a more accurate translation., the pressing member 230 is strip-shaped. The first ends of the two pressing members 230 are respectively connected to the two elastic clamping portions 220, and the second end of the pressing member 230 is the pressing portion 231. When an external force presses the two pressing portions 231, the front ends of the two elastic clamping portions 221 are driven to move away from each other, so that the clamping position 222 is in an open state.

[0044] Referring to Figure 1 and Figure 10 , during installation, an external force (manual pressing force) presses the two pressing portions 231 to drive the front ends of the two elastic clamping portions 221 to move away from each other, so that the clamping position 222 is in an open state. Then, the unlocking and locking knob of the anti-theft lock is inserted into the clamping position. After removing the external force, the front ends of the two elastic clamping portions 221 approach each other under the action of their own resilience, and the unlocking and locking knob of the anti-theft lock is fixedly clamped between the two elastic clamping portions 221. By means of the two pressing members 230, the two elastic clamping portions 221 are driven to elastically deform outward, and a relatively small force is used to open the clamping position 222, which is labor-saving in operation, convenient for installation, and simple in structure, greatly reducing the processing cost.

[0045] Specifically, referring to Figure 1 and Figure 10 , the length of the pressing member 230 is longer than the length of the elastic clamping portion 221, so that the middle part of the pressing member 230 can abut against the rear end of the elastic clamping portion 221, and the pressing portion 231 is located outside the elastic clamping portion 221. When an external force presses the two pressing portions 231, according to the lever principle, the abutting position between the middle part of the pressing member 230 and the rear end of the elastic clamping portion 221 is the fulcrum, and the two elastic clamping portions 221 can be easily driven to elastically deform outward, so that the clamping position 222 is opened, which is labor-saving in operation and convenient to operate.

[0046] Furthermore, referring to Figure 1 and Figure 10 , the rear ends of the two elastic clamping portions 221 extend and are connected to form an elastic connecting portion 223. The elastic connecting portion 223 is installed on the connecting main member 210, and the elastic connecting portion 223 and the two elastic clamping portions 221 are distributed in a triangular shape. Specifically, in this embodiment, the elastic connecting portion 223 and the two elastic clamping portions 221 are integrally formed structures, which are convenient for processing and firm in structure.

[0047] Preferably, referring to Figure 1 and Figure 10 , second rounded corners 225 are provided at the transitions of the joints between the two elastic clamping portions 221 and the elastic connecting portion 223. The second rounded corners 225 can provide better resilience for the elastic clamping portions 221, so that the two elastic clamping portions 221 have sufficient resilience to clamp the unlocking and locking knob of the anti-theft lock.

[0048] Furthermore, referring to Figure 1 and Figure 10A pair of mounting holes 224 are symmetrically defined on the front ends of the two elastic clamping portions 221, facing away from the clamping position 222. A gap is defined between the two mounting holes 224. Mounting shafts 232 are provided on opposite sides of the first ends of the two pressing members 230. The two mounting shafts 232 of each pressing member 230 are rotatably connected to the two mounting holes 224 of the corresponding elastic clamping portion 221, facilitating assembly. Specifically, the mounting holes 224 are formed by bending outwardly from the front ends of the elastic clamping portions 221, making them easy to manufacture.

[0049] Furthermore, refer to Figure 1 and Figure 10 The pressing member 230 is U-shaped, and the two mounting shafts 232 are respectively provided on either side of the U-shaped opening of the pressing member 230. When assembling the pressing member 230, a person manually presses the two sides of the U-shaped opening of the pressing member 230 to elastically deform inward, thereby reducing the U-shaped opening and thereby reducing the spacing between the two mounting shafts 232. At this time, the two mounting shafts 232 can be moved to the installation gap between the two mounting holes 224, so that the two mounting shafts 232 are respectively aligned with the two mounting holes 224. When the person manually releases the pressure on the two sides of the U-shaped opening of the pressing member 230, the two sides of the U-shaped opening of the pressing member 230 elastically return outward, allowing the two mounting shafts 232 to be respectively inserted into the two mounting holes 224, thereby facilitating assembly.

[0050] Specifically, refer to Figure 1 and Figure 10 The two mounting shafts 232 and the pressing member 230 are integrally formed, which is convenient for processing.

[0051] Preferably, refer to Figure 1 and Figure 10 The two elastic clamping parts 221 are each provided with a soft pad (not shown) on one side wall of the clamping position 222. The soft pad contacts the anti-theft lock's lock knob, preventing the elastic clamping parts 221 from scratching the lock knob, thus providing high practicality. The soft pad can be made of rubber, silicone EVA, etc., which has good elasticity and good friction, allowing the two elastic clamping parts 221 to firmly clamp the lock knob.

[0052] In another embodiment of the present invention, referring to Figure 9 and Figure 10 The main connecting member 210 includes a first connecting member 211, a second connecting member 212, and a third connecting member 213. The second connecting member 212 is slidably connected to the first connecting member 211 via a matching sliding groove and slider structure. The third connecting member 213 is slidably connected to the second connecting member 212 via a matching sliding groove and slider structure. The movement direction of the second connecting member 212 is perpendicular to the movement direction of the third connecting member 213. The clamping member 220 is installed in the middle of the third connecting member 213.

[0053] Reference Figure 9 and Figure 10 As shown in FIGS.

[0053] and Figure 9 , the first connecting member 211 is at least provided with a first sliding groove 2111 penetrating therethrough, and the second connecting member 212 is at least provided with a first sliding block 2121 slidably connected to the first sliding groove 2111. An end of the first sliding block 2121 is provided with a first threaded hole 2122, and a first screw (not shown in the figure) is threadedly connected to the first threaded hole 2122. The diameter of the nut of the first screw is greater than the width of the first sliding groove 2111, and the nut of the first screw is close to the first connecting member 211, so that the first sliding block 2121 is stably slidably connected to the first sliding groove 2111.

[0054] Specifically, referring to Figure 9 and Figure 10 As shown in FIGS. Figure 9 and Figure 10 , the first connecting member 211 is symmetrically provided with two first sliding grooves 2111. Correspondingly, the second connecting member 212 is symmetrically provided with two first sliding blocks 2121, so that the second connecting member 212 can stably slide along the two first sliding grooves 2111, and the structure is stable.

[0055] Reference Figure 9 and Figure 10 As shown in FIGS. Figure 9 and Figure 10 , the second connecting member 212 is at least provided with a second sliding groove 2123 penetrating therethrough. The second sliding groove 2123 is perpendicular to the first sliding groove 2111. The third connecting member 213 is at least provided with a second sliding block 2131 slidably connected to the second sliding groove 2123. An end of the second sliding block 2131 is provided with a second threaded hole 2132, and a second screw (not shown in the figure) is threadedly connected to the second threaded hole 2132. The diameter of the nut of the second screw is greater than the width of the second sliding groove 2123, and the nut of the second screw is close to the second connecting member 212, so that the second sliding block 2131 is stably slidably connected to the second sliding groove 2123.

[0056] Specifically, referring to Figure 9 and Figure 10 As shown in FIGS. Figure 9 and Figure 10 , the second connecting member 212 is symmetrically provided with two second sliding grooves 2123, and the third connecting member 213 is symmetrically provided with two second sliding blocks 2131. The two second sliding blocks 2131 are respectively slidably connected to the two second sliding grooves 2123, so that the third connecting member 213 can stably slide along the second sliding groove 2123, and the structure is stable.

[0057] Furthermore, referring to Figure 9 and Figure 10, one end of the third connecting member 213 facing away from the second connecting member 212 is provided with a connecting groove 2133, and the elastic connecting portion 223 of the clamping member 220 is fixedly installed on a connecting block 240. Specifically, the elastic connecting portion 223 can be fixed on the connecting block 240 by means of clamping, bonding, screw connection, etc., which is convenient for installation. Specifically, the width of the connecting block 240 is less than or equal to the width of the elastic connecting portion. One end of the connecting block 240 facing away from the clamping member 220 is provided with a plugging portion 241, and the plugging portion 241 is slidably connected to the connecting groove 2133. Among them, the plugging portion and the connecting groove 2133 are connected by the connection method of a sliding groove and a slider, which is convenient for installation.

[0058] Referring to Figure 1 , Figure 9 and Figure 10 , when installing the unlocking and locking robot, due to different operators, the unlocking and locking knob of the anti-theft lock cannot be accurately clamped at the exact center position between the two elastic clamping portions 221, but the unlocking and locking knob is eccentrically clamped between the two elastic clamping portions 221. The second connecting member 212 is arranged to be slidably connected to the first connecting member 211, and the third connecting member 213 is arranged to be slidably connected to the second connecting member 212. Therefore, when the unlocking and locking robot drives the unlocking and locking knob held between the two elastic clamping portions 221 to rotate through the first connecting member 211, the second connecting member 212 and the third connecting member 213, the second connecting member 212 and the third connecting member 213 can slide and adjust their positions. Even if the rotation center of the unlocking and locking knob and the rotation center of the output gear 340 do not coincide during installation, the driving mechanism 500 can still drive the unlocking and locking knob to rotate smoothly without the phenomenon of rotation jamming. At the same time, without considering whether the unlocking and locking knob is accurately clamped at the exact center position between the two elastic clamping portions 221, a certain installation deviation is allowed, which is convenient for installation and has extremely high practicability.

[0059] In another embodiment of the present invention, referring to Figure 1 and Figure 2 , an unlocking and locking robot is provided, which has the above-mentioned connecting mechanism 200.

[0060] Referring to Figure 1 and Figure 2 , the unlocking and locking robot further includes a housing main body 100, a transmission mechanism 300, a clutch mechanism 400 and a driving mechanism 500.

[0061] Referring to Figure 1 and Figure 2 , the first connecting member 211 of the connecting mechanism 200 is rotatably connected to the housing main body 100, and the connecting mechanism 200 is used for connecting with the unlocking and locking knob of the anti-theft lock.

[0062] Referring to Figure 1 and Figure 2, The transmission mechanism 300, the clutch mechanism 400, and the driving mechanism 500 are all installed inside the housing main body 100. The output end of the transmission mechanism 300 is connected to the first connecting member 211 of the connecting mechanism 200, and a clutch mechanism 400 is installed between the input end of the transmission mechanism 300 and the output end of the driving mechanism 500. When the driving mechanism 500 operates, the clutch mechanism 400 makes the input end of the transmission mechanism 300 and the output end of the driving mechanism 500 in transmission connection. When the driving mechanism 500 stops, the clutch mechanism 400 makes the input end of the transmission mechanism 300 and the output end of the driving mechanism 500 release the transmission connection.

[0063] Refer to Figure 1 and Figure 2 , In use, when the driving mechanism 500 operates, the clutch mechanism 400 makes the input end of the transmission mechanism 300 and the output end of the driving mechanism 500 in transmission connection, so that the driving mechanism 500 can drive the connecting mechanism 200 to rotate. And the connecting mechanism 200 is connected to the unlocking and locking knob of the anti-theft lock, thereby driving the unlocking and locking knob to rotate forward or backward to realize automatic unlocking and automatic locking of the anti-theft lock. When the driving mechanism 500 stops, the clutch mechanism 400 makes the input end of the transmission mechanism 300 and the output end of the driving mechanism 500 release the transmission connection. At this time, manually rotating or turning the unlocking and locking knob with a key will not drive the rotating shaft of the driving mechanism 500 to rotate, and will not cause wear or damage to the driving mechanism 500, improving the service life of the unlocking and locking robot.

[0064] Therefore, the unlocking and locking robot of the present invention can perform automatic unlocking and automatic locking on the anti-theft lock, and can also perform manual unlocking and manual locking on the anti-theft lock manually by people. The unlocking and locking methods are diverse, the structural design is reasonable, and it is comfortable for people to use.

[0065] In another embodiment of the present invention, refer to Figure 3 and Figure 4 , the clutch mechanism 400 includes a clutch main part 410, a swing arm 420, a linkage part 430, a traction part 440, and a driving mechanism 500. A cylindrical installation groove 411 is provided inside the clutch main part 410, and at least one linkage groove 412 is provided on the circumferential inner wall of the cylindrical installation groove 411.

[0066] Refer to Figure 4 , Figure 5 and Figure 6 , the driving mechanism 500 is fixedly installed in the unlocking and locking robot, and the output end of the driving mechanism 500 is inserted into the center of the cylindrical installation groove 411 and is rotationally connected to the clutch main part 410. The swing arm 420 is installed at the output end of the driving mechanism 500 and is driven by the driving mechanism 500 to rotate inside the cylindrical installation groove 411. The linkage part 430 and the traction part 440 are installed inside the cylindrical installation groove 411.

[0067] Refer toFigure 4 , Figure 5 and Figure 6 , when the driving mechanism 500 operates, the driving mechanism 500 drives the swing arm 420 to rotate around the output end of the driving mechanism 500 within the cylindrical mounting groove 411, causing the swing arm 420 to push the linkage member 430 to move. The linkage member 430 is partially received in the linkage groove 412 under the action of the driving force and centrifugal force of the swing arm 420, and the part of the linkage member 430 extending outside the linkage groove 412 abuts against the swing arm 420, so that the swing arm 420, the linkage member 430 and the clutch main member 410 are abutted in sequence, making the output end of the driving mechanism 500 in transmission connection with the clutch main member 410, thereby driving the clutch main member 410 to rotate. In the unlocking and locking robot, the rotation of the clutch main member 410 drives the unlocking and locking knob of the anti-theft lock to rotate through the transmission mechanism 300 and the rotary clamping mechanism 200, realizing automatic unlocking and automatic locking of the anti-theft lock.

[0068] Referring to Figure 4 , Figure 5 and Figure 6 , when the driving mechanism 500 stops, the traction member 440 pulls the linkage member 430 out of the linkage groove 412. At this time, the clutch main member 410 is disengaged from the transmission connection with the swing arm 420, and thus the clutch main member 410 is disengaged from the transmission connection with the output end of the driving mechanism 500. Manually rotating or turning the unlocking and locking knob with a key, the rotation of the unlocking and locking knob drives the clutch main member 410 to rotate, and the transmission connection between the clutch main member 410 and the output end of the driving mechanism 500 is disengaged. In this way, only the clutch main member 410 rotates, and the rotating shaft of the driving mechanism 500 does not rotate, which will not cause wear or damage to the driving mechanism 500, thereby improving the service life of the driving mechanism 500. At the same time, the clutch mechanism has a simple structure, is reliable, and is convenient for mass manufacturing and processing.

[0069] It can be understood that the principle of the driving mechanism 500 rotating forward or backward to drive the clutch main member 410 to rotate forward or backward through the swing arm 420 and the linkage member 430 is the same.

[0070] Preferably, there are four linkage grooves 412, and the four linkage grooves 412 are annularly and evenly distributed on the side wall of the cylindrical mounting groove 411, so that when the swing arm 420 rotates, it can push the linkage member 420 to quickly connect with one of the linkage grooves 412, thereby improving the transmission efficiency.

[0071] In another embodiment of the present invention, referring to Figure 4 , Figure 5 and Figure 6 , at least one of the materials of the linkage member 430 and the traction member 440 is a magnet, and the other is a magnet or a metal that can be adsorbed by the magnet. The linkage member 430 and the traction member 440 are magnetically attracted to each other, so that when the driving mechanism 500 stops, the traction member 440 can pull the linkage member 430 out of the linkage groove 412.

[0072] Specifically, in some embodiments, the materials of the linkage member 430 and the traction member 440 are both magnets. The traction member 440 is fixedly installed in the middle of the covering member 450, and the traction member 440 is smaller than or slightly smaller than the cylindrical installation groove 411. One end of the linkage member 430 and the traction member 440 that are close to each other attract each other magnetically, so that the traction member 440 can pull the linkage member 430 out of the linkage groove 412.

[0073] Specifically, in some other embodiments, referring to Figure 4 , Figure 5 and Figure 6 , the material of the linkage member 430 is a magnet, and the material of the traction member 440 is iron. Due to the magnetic attraction between iron and the magnet, the traction member 440 can pull the linkage member 430 out of the linkage groove 412.

[0074] Specifically, in other embodiments, referring to Figure 4 , Figure 5 and Figure 6 , the material of the linkage member 430 is iron, and the material of the traction member 440 is a magnet. Due to the magnetic attraction between iron and the magnet, the traction member 440 can pull the linkage member 430 out of the linkage groove 412.

[0075] In another embodiment of the present invention, referring to Figure 4 , the linkage member 430 is cylindrical. Correspondingly, the linkage groove 412 is semi-cylindrical and adapted to the linkage member 430, so that the linkage member 430 can be stably and partially accommodated in the linkage groove 412. Specifically, the length of the linkage member 430 is adapted to the depth of the cylindrical installation groove 411, so that the linkage member 430 can move stably in the cylindrical installation groove 411, avoiding skew of the linkage member 430 during movement and ensuring structural stability.

[0076] In some embodiments, the linkage member 430 is spherical. Correspondingly, the linkage groove 412 is hemispherical and adapted to the linkage member 430, so that the linkage member 430 can be stably and partially accommodated in the linkage groove 412. Specifically, the diameter of the linkage member 430 is adapted to the depth of the cylindrical installation groove 411, so that the linkage member 430 can move stably in the cylindrical installation groove 411, and the movement stability is good.

[0077] Specifically, the cross-section of the linkage groove 412 is semi-circular or smaller than semi-circular, and the center of the cross-section of the linkage groove 412 is in the cylindrical installation groove 411, so that the linkage member 430 can effectively extend into the linkage groove 412 and be adapted to the linkage groove 412.

[0078] In another embodiment of the present invention, referring to Figure 4, the cylindrical installation groove 411 extends to one end of the clutch main part 410 and forms an opening. A cover part 410 is adapted to cover the opening, so as to form a closed cavity in the cylindrical installation groove 411, which is convenient for installing the linkage part 430, the swing arm 420 and the traction part 440. Specifically, in this embodiment, the cover part 410 is fixedly installed on the driving mechanism 500, and the cover part 410 is rotatably connected to the clutch main part 410. The output end of the driving mechanism 500 movably passes through the cover part 410 and inserts into the center of the cylindrical installation groove 411.

[0079] Further, referring to Figure 4 , Figure 5 and Figure 6 , a traction part installation groove 451 is dug in the middle of the end face of the cover part 450 located in the cylindrical installation groove 411. The traction part 440 is adapted to be accommodated in the traction part installation groove 451, and the end face of the traction part 440 is flush with the end face of the cover part 450. Among them, the traction part 440 can be fixed to the cover part 450 by interference clamping, bonding and other methods.

[0080] Furthermore, the traction part 440 is circular, and the diameter of the traction part 440 is smaller than the diameter of the cylindrical installation groove 411, ensuring that the traction part 440 can pull the linkage part 430 completely out of the linkage groove 412.

[0081] In another embodiment of the present invention, referring to Figure 4 and Figure 5 , the driving mechanism 500 is a motor. The rotating shaft 510 of the motor passes through the center of the cover part 450 and extends into the center of the cylindrical installation groove 411. The swing arm 420 is fixedly installed on the rotating shaft 510 of the motor.

[0082] In some embodiments, the swing arm 420 is a swing block. One end of the swing block is fixedly installed on the rotating shaft 510 of the motor, and the other end of the swing block is close to the circumferential inner wall of the cylindrical installation groove 411.

[0083] In other embodiments, the swing arm 420 is a swing rod with two symmetric ends. The middle part of the swing rod is fixedly installed on the rotating shaft 510 of the motor, and the two ends of the swing rod are respectively close to the circumferential inner walls on the opposite sides of the cylindrical installation groove 411.

[0084] It should be noted that after the motor drives the swing arm 420 to rotate to drive the unlocking and locking knob of the anti-theft lock to rotate to complete automatic unlocking or automatic locking, then the motor drives the swing arm 420 to rotate a certain distance in the direction opposite to the previous rotation direction, and then the motor stops rotating, so that the swing arm 420 is disengaged from abutting against the linkage part 430. At this time, the linkage part 430 loses the driving force and centrifugal force of the swing arm 420, and the linkage part 430 moves away from the linkage groove 412 and moves onto the traction part 440 under the traction force of the traction part 440, so that the linkage part 430 is disengaged from the linkage groove 412.

[0085] Further, referring to Figure 4 , a rotation hole 311 is provided through the axis of the clutch main part 410, the rotating shaft 510 of the motor passes through the rotation hole 311, and the rotation hole 311 of the clutch main part 410 is rotationally connected to the rotating shaft 510 of the motor through a bearing. When the motor is in a non-operating state, the clutch main part 410 is rotationally connected to the rotating shaft 510 of the motor, and the structure is stable.

[0086] Among them, the unlocking and locking robot further includes a power supply 101 and a control circuit board 102 installed in the housing main body 100. The control circuit board 102 is electrically connected to the power supply 101 and the motor (driving mechanism 500). The control circuit board 102 is a mature existing technology. For example, an induction switch is provided on the control circuit board 102, and an induction system matching the induction switch of the control circuit board 102 is installed on the card or the mobile phone. When the card and the mobile phone are close to the unlocking and locking robot at a certain distance, the motor starts to work for automatic unlocking, and when the card and the mobile phone are far from the unlocking and locking robot at a certain distance, the motor starts to work for automatic locking. The above technologies are mature existing technologies. For example, when the intelligent key of a car approaches the car, the car door can be automatically unlocked without pressing the button on the key. Therefore, the technology of how to control the unlocking and locking robot for automatic unlocking and automatic locking is a mature existing technology, and the present invention will not elaborate on it here.

[0087] Specifically, referring to Figure 2 , the power supply 101 is installed in the battery compartment, and the battery compartment can be fixedly installed in the housing main body 100 by means of snap connection, bonding, screw connection, etc., which is convenient for installation.

[0088] In some embodiments, referring to Figure 2 , the battery compartment and the housing main body 100 are integrally formed, which is convenient for processing, saves parts, and reduces processing costs.

[0089] In another embodiment of the present invention, referring to Figure 2 , Figure 7 and Figure 8 , the transmission mechanism 300 includes a gear mounting bracket 310 installed in the housing main body 100, an input gear 320, a connecting gear 330, and an output gear 340 that are all rotatably connected to the gear mounting bracket 310. The input gear 320 is connected to the connecting gear 330, the connecting gear 330 is connected to the output gear 340, the radius of the input gear 320 is smaller than the radius of the connecting gear 330, and the radius of the connecting gear 330 is smaller than the radius of the output gear 340.

[0090] Further, referring to Figure 7 and Figure 8, a first rotating shaft 321 is provided at the axis of the input gear 320. The first rotating shaft 321 is rotatably connected to the gear mounting bracket 310 through a bearing. A second rotating shaft 331 is provided at the axis of the connecting gear 330. The second rotating shaft 331 is rotatably connected to the gear mounting bracket 310 through a bearing. A third rotating shaft 341 is provided at the axis of the output gear 340. The third rotating shaft 341 is rotatably connected to the gear mounting bracket 310 through a bearing. Rotationally mounting the input gear 320, the connecting gear 330, and the output gear 340 on a gear mounting bracket 310 is convenient for installation. At the same time, the installation accuracy is high, ensuring high transmission accuracy between the input gear 320, the connecting gear 330, and the output gear 340, with small movement resistance and smooth movement.

[0091] Among them, referring to Figure 7 and Figure 8 , the input gear 320 is connected to and coaxially arranged with the clutch main part 410 of the clutch mechanism 400. Specifically, in this embodiment, the first gear 310 and the clutch main part 410 are integrally formed, which is convenient for processing and has a firm structure.

[0092] Among them, referring to Figure 7 and Figure 8 , the output gear 340 is connected to and coaxially arranged with the first connecting member 211 of the connecting main member 210. Specifically, in this embodiment, the output gear and the first connecting member 211 are integrally formed, which is convenient for processing and has a firm structure.

[0093] Specifically, referring to Figure 2 , Figure 7 and Figure 8 , the torque output by the driving mechanism 500 is transmitted through the input gear 320, the connecting gear 330, and the output gear 340 to amplify and output the torque, so that the torque at the output end of the output gear 340 is relatively large. Thus, the output gear 340 can more easily drive the unlocking and locking knob to rotate through the connecting mechanism 200 without jamming and with smooth movement.

[0094] Specifically, referring to Figure 7 and Figure 8 , convex blocks 311 are provided on both opposite sides of the gear mounting bracket 310. The input gear 320 and the connecting gear 330 are both located between the two convex blocks 311. The two convex blocks 311 have a protective effect, making it difficult for other objects to touch the input gear 320 and the connecting gear 330.

[0095] Furthermore, referring to Figure 7 and Figure 8 , an encoder 350 is sleeved on the first rotating shaft 321, the second rotating shaft 331, or the third rotating shaft 341. The encoder 350 is electrically connected to the control circuit board 102.

[0096] Specifically, in this embodiment, referring to Figure 7 and Figure 8 The encoder 350 is mounted on the second rotating shaft 331 and accurately calculates the rotation angle or angular displacement of the connecting gear 330. The encoder, through the input gear 320, the connecting gear 330, and the output gear 340, can calculate the angle of rotation of the lock knob when it is rotated to the unlocked or locked position. That is, when the lock knob is rotated to the unlocked or locked position, the encoder 350 transmits an electrical signal to the drive mechanism 500, causing the drive mechanism 500 to stop rotating. The encoder 350 is a mature existing component, and therefore, how the encoder 350 is controlled is not detailed in this embodiment.

Screws (not shown) pass through the fixing holes 312 and are threadedly connected to the screw columns 140 to fix the gear mounting frame 310 in the shell body 100 and install it firmly.

[0098] Further, refer to Figure 2 、 Figure 7 and Figure 8 The housing body 100 has two oppositely facing walls, each with a first connection hole 120 and a second connection hole 130. Specifically, both the first connection hole 120 and the second connection hole 130 are circular holes. The first connection member 211 movably passes through the first connection hole 120 and extends out of the housing body 100. A socket is defined at the axis of the knob member 360. One end of the third rotating shaft 341 movably passes through the gear mounting bracket 310 and is fixedly inserted into the socket, thereby securely connecting the knob member 360 to the third rotating shaft 341. The knob member 360 is rotatably connected to the second connection hole 130 and extends out of the housing body 100.

[0099] Furthermore, refer to Figure 7 and Figure 8 A straight-line knob block 361 is provided on one end of the knob member 360 facing away from the gear mounting frame 310, and the knob block 361 extends out of the housing body 100. The knob block 361 facilitates turning the knob member 360. When a person is inside the door, the knob block 361 rotates, and the knob block 361 drives the anti-theft lock's unlocking and locking knob to rotate via the second gear 320 and the rotary clamping mechanism 200, thereby allowing the anti-theft lock to be manually unlocked and locked, making it convenient for people to use.

[0100] The remaining parts of this embodiment are the same as those of the first embodiment. For the features not explained in this embodiment, the explanations of the first embodiment are adopted and will not be elaborated here.

[0101] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, its architecture form can be flexibly changed, and a series of products can be derived.
