Description

Technical Field

[0001] The present invention belongs to the technical field of opening and closing devices, and particularly relates to an opening and closing robot. Background Art

[0002] Currently, anti-theft locks are widely used on doors in various occasions due to their high security. There are various anti-theft locks on the market, such as: conventional anti-theft locks, password lock type anti-theft locks, fingerprint lock type anti-theft locks, etc. Among them, password lock type anti-theft locks and fingerprint lock type anti-theft locks can achieve the functions of automatic unlocking and automatic locking. Conventional anti-theft locks are manually unlocked and locked with a key. For newly renovated occasions, directly installing password lock type anti-theft locks and fingerprint lock type anti-theft locks can achieve the functions of automatic unlocking and automatic locking. For doors that have already installed conventional anti-theft locks, in order to have the functions of automatic unlocking and automatic locking, the entire anti-theft lock or the entire door can only be replaced. However, due to the different shapes and sizes of the lock bodies of users' anti-theft locks, the new and old lock bodies often do not match, and it is necessary to make holes and grooves on the door on-site for modification. The replacement is complex, the workload is large, and the cost is high.

[0003] Therefore, an opening and closing robot has emerged. The opening and closing robot is a device installed on the anti-theft lock of a door to automatically unlock and lock the anti-theft lock. There is no need to replace the entire anti-theft lock or the entire door. Just install the opening and closing robot on a conventional anti-theft lock, and the anti-theft lock can have the functions of automatic unlocking and automatic locking. The installation is convenient, the workload is small, and the cost is low. The existing opening and closing robot includes a housing main body, a connecting head, and a motor. The housing main body is installed on the anti-theft lock or the door. The connecting head is rotatably connected to the housing main body, and the connecting head is connected to the opening and closing knob of the anti-theft lock. The motor is installed inside the housing main body and drives the connecting head to rotate forward or backward, thereby driving the opening and closing knob of the anti-theft lock to rotate forward or backward to achieve the functions of automatic unlocking and automatic locking of the anti-theft lock.

[0004] However, the existing opening and closing robot cannot be manually unlocked or locked. People can only wait for a few seconds outside or inside the door for the opening and closing robot to drive the anti-theft lock to automatically unlock and lock, which will cause people to have a waiting time and thus discomfort. Since the opening and closing knob of the anti-theft lock is connected to the motor shaft through a connecting mechanism, if forced manual unlocking or locking is carried out, the opening and closing knob will be twisted and rotated. At this time, the motor shaft is in a stationary state, and twisting the opening and closing knob will force the motor shaft to rotate along with it. The force is large, which is likely to cause wear or damage to the motor and greatly reduce the service life of the motor. Summary of the Invention

[0036] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0037] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0038] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, 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.

[0039] In the embodiments of the present invention, unless otherwise clearly defined and limited, terms such as "installed", "connected", "linked", "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.

[0040] In one embodiment of the present invention, referring to Figure 1 , Figure 2 and Figure 3 , a locking and unlocking robot is provided, which includes a housing main body 100, a connecting mechanism 200, a transmission mechanism 300, a clutch mechanism 400, and a driving mechanism 500.

[0041] The connecting mechanism 200 is rotatably connected to the housing main body 100 and is located outside the housing main body 100. The connecting mechanism 200 is used to connect with the locking and unlocking knob of the anti-theft lock.

[0042] 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 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 disconnect from the transmission connection.

[0043] Compared with the prior art, the locking and unlocking robot provided by the embodiments of the present invention has one of the following technical effects:

[0044] During use, the drive mechanism 500 operates, and the clutch mechanism 400 drives the input end of the transmission mechanism 300 to be in transmission connection with the output end of the drive mechanism 500, enabling the drive mechanism 500 to drive the connection mechanism 200 to rotate. The connection 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, realizing automatic unlocking and automatic locking of the anti-theft lock. When the drive mechanism 500 stops, the clutch mechanism 400 disengages the transmission connection between the input end of the transmission mechanism 300 and the output end of the drive mechanism 500. At this time, manually rotating or turning the unlocking and locking knob with a key will not drive the rotating shaft of the drive mechanism 500 to rotate, and will not cause wear or damage to the drive mechanism 500, improving the service life of the unlocking and locking robot. Therefore, the unlocking and locking robot of the present invention can automatically unlock and lock the anti-theft lock, and can also manually unlock and lock the anti-theft lock manually by a person. The unlocking and locking methods are diverse, and the structural design is reasonable, making it comfortable for people to use.

[0045] In another embodiment of the present invention, referring to Figure 2 , Figure 4 and Figure 5 , the clutch mechanism 400 includes a clutch main part 410, a swing arm 420, a linkage part 430, a traction part 440, and a drive mechanism 500. A cylindrical installation groove 411 is provided in 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.

[0046] Referring to Figure 4 , Figure 5 and Figure 6 , the drive mechanism 500 is fixedly installed in the unlocking and locking robot, and the output end of the drive mechanism 500 is inserted into the center of the cylindrical installation groove 411 and is rotatably connected to the clutch main part 410. The swing arm 420 is installed at the output end of the drive mechanism 500 and is driven by the drive mechanism 500 to rotate in the cylindrical installation groove 411. The linkage part 430 and the traction part 440 are installed in the cylindrical installation groove 411.

[0047] Referring to Figure 6 and Figure 7, 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 within the linkage groove 412 under the action of the driving force and centrifugal force of the swing arm 420, and the portion of the linkage member 430 extending outside the linkage groove 412 abuts against the swing arm 420, such that the swing arm 420, the linkage member 430, and the clutch main member 410 are sequentially in contact, enabling the output end of the driving mechanism 500 to be 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 connection mechanism 200, realizing automatic unlocking and automatic locking of the anti-theft lock.

[0048] Referring to Figure 6 and Figure 7 , 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, preventing wear or damage to the driving mechanism 500, thereby increasing 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.

[0049] It can be understood that the principle of the output end 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.

[0050] 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, such that when the swing arm 420 rotates, it can quickly push the linkage member 420 to connect with one of the linkage grooves 412, thereby improving the transmission efficiency.

[0051] In another embodiment of the present invention, referring to Figure 6 and Figure 7 , 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 a 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.

[0052] 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.

[0053] Specifically, in some other embodiments, referring to Figure 6 and Figure 7 , 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.

[0054] Specifically, in other embodiments, referring to Figure 6 and Figure 7 , 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.

[0055] In another embodiment of the present invention, referring to Figure 5 , 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 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 stably move in the cylindrical installation groove 411, avoiding skew of the linkage member 430 during movement and ensuring structural stability.

[0056] 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 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 stably move in the cylindrical installation groove 411 with good movement stability.

[0057] 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.

[0058] In another embodiment of the present invention, referring to Figure 6 and Figure 7, the cylindrical mounting groove 411 extends to one end of the clutch main member 410 and forms an opening, and a covering member 410 is adapted to cover the opening, so as to form a closed cavity in the cylindrical mounting groove 411, which is convenient for installing the linkage member 430, the swing arm 420 and the traction member 440. Specifically, in this embodiment, the covering member 410 is fixedly installed on the driving mechanism 500, and the covering member 410 is rotatably connected to the clutch main member 410. The output end of the driving mechanism 500 movably passes through the covering member 410 and is inserted into the center of the cylindrical mounting groove 411.

[0059] Further, referring to Figure 6 and Figure 7 , a traction member mounting groove 451 is dug in the middle of the end face of the covering member 450 located in the cylindrical mounting groove 411, the traction member 440 is adapted to be accommodated in the traction member mounting groove 451, and the end face of the traction member 440 is flush with the end face of the covering member 450. Among them, the traction member 440 can be fixed to the covering member 450 by interference clamping, bonding and other methods.

[0060] Furthermore, the traction member 440 is circular, and the diameter of the traction member 440 is smaller than the diameter of the cylindrical mounting groove 411, ensuring that the traction member 440 can completely pull the linkage member 430 out of the linkage groove 412.

[0061] 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 covering member 450 and extends into the center of the cylindrical mounting groove 411, and the swing arm 420 is fixedly installed on the rotating shaft 510 of the motor.

[0062] 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 mounting groove 411.

[0063] In other embodiments, the swing arm 420 is a swing rod with symmetric ends, the middle 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 of the opposite sides of the cylindrical mounting groove 411.

[0064] Further, referring to Figure 5 , a rotating hole 311 is penetrated through the axis of the clutch main member 410, the rotating shaft 510 of the motor passes through the rotating hole 311, and the rotating hole 311 of the clutch main member 410 is rotatably connected to the rotating shaft 510 of the motor through a bearing. When the motor is in a non-working state, the clutch main member 410 is rotatably connected to the rotating shaft 510 of the motor, and the structure is stable.

[0065] 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, the motor then 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 disengages from the abutment with the linkage member 430. At this time, the linkage member 430 loses the driving force and centrifugal force of the swing arm 420, and the linkage member 430 moves away from the linkage groove 412 and moves onto the traction member 440 under the traction force of the traction member 440, so that the linkage member 430 disengages from the linkage groove 412.

[0066] 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 (drive 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 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 technology is a mature existing technology. 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 for controlling the unlocking and locking robot to perform automatic unlocking and automatic locking is a mature existing technology, and the present invention will not elaborate on it here.

[0067] In another embodiment of the present invention, referring to Figure 2 and Figure 8 , the transmission mechanism 300 includes a first gear 310 and a second gear 320 that are both rotatably connected in the housing main body 100, and the first gear 310 is meshed with the second gear 320.

[0068] Referring to Figure 2 , Figure 5 and Figure 8 , the clutch main part 410 is installed on the first gear 310 and is coaxially arranged with the first gear 310. Therefore, when the motor is in the non-working state, both the first gear 310 and the clutch main part 410 are rotatably connected to the rotating shaft 510 of the motor, and the movement is stable.

[0069] In some embodiments, the clutch main part 410 and the first gear 310 are integrally formed, which is convenient for processing and has a firm structure.

[0070] Referring to Figure 2 and Figure 8The second gear 320 is provided with a first gear shaft 321 and a second gear shaft 322 at both ends. The housing body 100 has two oppositely facing walls formed with a first connecting hole 120 and a second connecting hole 130. Specifically, the first connecting hole 120 and the second connecting hole 130 are both circular holes, and the first gear shaft 321 is rotatably connected to the first connecting hole 120. The connecting mechanism 200 is fixedly connected to the first gear shaft 321 of the second gear 320 through the first connecting hole 120. A knob 330 is fixedly connected to the second gear shaft 322 of the second gear 320 through the second connecting hole 130, and the knob 330 is rotatably connected to the second connecting hole 130.

[0071] Further, refer to Figure 2 and Figure 8 The second end gear shaft 322 is symmetrically provided with two first sockets, and the knob member 330 is symmetrically provided with two first plugs at one end close to the second end gear shaft 322. The two first plugs are respectively adapted to be plugged into the two first sockets, so that the knob member 330 is fixedly connected to the second gear shaft 322.

[0072] It is understandable that the first plug can be fixedly inserted into the first plug hole by interference fit, snap connection, bonding, etc., which is convenient for installation.

[0073] In some embodiments, the knob member 430 can be fixedly connected to the second gear shaft 422 by screws, which is easy to install and has a stable connection.

[0074] Furthermore, refer to Figure 2 and Figure 8 A straight-shaped knob block 331 is provided on the end of the knob member 330 facing away from the second end gear shaft 322, and the knob block 331 extends out of the housing body 100. The knob block 331 is convenient for people to turn the knob member 330. When people are inside the door, they turn the knob block 331, which drives the anti-theft lock's unlocking and locking knob to rotate through the second gear 320 and the connecting mechanism 200, thereby manually unlocking and locking the anti-theft lock, making it convenient for people to use.

[0075] In another embodiment of the present invention, referring to Figure 8 and Figure 10 The connecting mechanism 200 includes a connecting main part 210, two clamping parts 220 and an adjusting key 230.

[0076] Reference Figure 8 and Figure 10, the first end of the connecting main part 210 is installed at the output end of the transmission mechanism 300 (i.e., the first gear shaft 321), the second end of the connecting main part 210 is provided with a mounting seat 240, both clamping parts 220 are slidably connected to the mounting seat 240, and a clamping position is formed between the two clamping parts 220. During installation, the unlocking and locking knob of the anti-theft lock is fixedly clamped at the clamping position.

[0077] Further, referring to Figure 11 and Figure 12 , one end of the mounting seat 240 away from the connecting main part 210 is provided with an inverted T-shaped sliding groove 241, the lower ends of both clamping parts 220 are provided with inverted T-shaped sliding blocks 221, and both inverted T-shaped sliding blocks 221 are slidably connected to the inverted T-shaped sliding groove 241, so that both clamping parts 220 are slidably connected to the mounting seat 240. Among them, the inverted T-shaped sliding groove 241 penetrates through both sides of the mounting seat 240, facilitating the installation of both inverted T-shaped sliding blocks 221 into the inverted T-shaped sliding groove 241.

[0078] Referring to Figure 11 and Figure 12 , the adjusting key 230 is movably installed on the mounting seat 240 and is used to drive the two clamping parts 220 to approach or move away from each other. Since the sizes of the unlocking and locking knobs of different anti-theft locks are different, the distance between the two clamping parts 220 is set to be adjustable, which is not only convenient for installation and firm in connection, but also adapts to unlocking and locking knobs of different sizes, with high adaptability.

[0079] Further, referring to Figure 11 and Figure 12 , a circular adjusting groove 231 is dug at one end of the adjusting key 230, a connecting shaft 242 is provided at the center of the lower end of the mounting seat 240, the center of the adjusting key 230 is rotatably connected to the connecting shaft 242 of the mounting seat 240 and the mounting seat 240 is located in the circular adjusting groove 231. Both clamping parts 220 extend out of the circular adjusting groove 231.

[0080] Referring to Figure 11 and Figure 12 , a spiral adjusting protrusion 232 is provided at the bottom of the circular adjusting groove 231, and the spiral adjusting protrusion 232 spirals from the center of the circular adjusting groove 231 to the outside of the circular adjusting groove 231. Adjusting blocks 222 are respectively protruded at one ends of the inverted T-shaped sliding blocks 221 of both clamping parts 220 close to the spiral adjusting protrusion 232, and adjusting grooves 223 are respectively provided at the ends of both adjusting blocks 222. An avoidance groove for avoiding the adjusting block 222 is opened at the bottom of the inverted T-shaped sliding groove 221. The two adjusting grooves 223 are respectively adapted to be sleeved on two opposite sections of protrusions on both sides of the spiral adjusting protrusion 232. Specifically, the spiral adjusting protrusion 232 has multiple turns of protrusions.

[0081] Referring to Figure 10 、 Figure 11 and Figure 12, Rotating the adjustment key 230 drives the spiral adjustment protrusion 232 to rotate. Both adjustment grooves 223 slide relative to the protrusion of the spiral adjustment protrusion 232, causing the two adjustment grooves 223 to slide onto different protrusions on opposite sides of the spiral adjustment protrusion 232 respectively, thereby driving the two clamping members 220 to approach or move away from each other along the inverted T-shaped sliding groove 221, enabling the two clamping members 220 to fixedly clamp unlocking knobs of different sizes.

[0082] Further, referring to Figure 11 and Figure 12 , the upper end of the spiral adjustment protrusion 232 is provided with first rounded corners on both opposite sides, and the opposite side walls of the adjustment groove 223 are provided with arc surfaces. The first rounded corners are adapted to fit and the arc surfaces are adapted to abut. When rotating the adjustment key 230, the arc surface fits and slides relative to the arc wall, with small friction, so that the friction between the adjustment groove 223 and the spiral adjustment protrusion 232 is small, reducing wear and enabling smooth movement at the same time.

[0083] In another embodiment of the present invention, referring to Figure 8 , the connecting main member 210 includes a first connecting member 211, a second connecting member 212, and a third connecting member 213. The first connecting member 211 is installed at the output end of the transmission mechanism 300 (i.e., the first gear shaft 321). Specifically, two second insertion posts 2110 are symmetrically provided at one end of the first connecting member 211 close to the first gear shaft 321, and two second insertion holes 3210 are symmetrically provided on the first gear shaft 321. The two second insertion posts 2110 are respectively adapted to be inserted into the two second insertion holes 3210, so that the first connecting member 211 is fixedly connected to the first gear shaft 321.

[0084] It can be understood that the second insertion post 2110 can be fixedly inserted into the second insertion hole 3210 by means of interference fit, clamping, bonding, etc., which is convenient for installation.

[0085] Referring to Figure 8 , the first connecting member 211 is at least provided with a first sliding groove 2111, and the second connecting member 212 is at least provided with a first sliding block 2121 slidably connected to the first sliding groove 2111. A first threaded hole 2122 is provided at the end of the first sliding block 2121, 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 abuts against the first connecting member 211, so that the first sliding block 2121 is stably slidably connected to the first sliding groove 2111.

[0086] Specifically, two first sliding grooves 2111 are symmetrically provided on the first connecting member 211. Correspondingly, two first sliding blocks 2121 are symmetrically provided on the second connecting member 212, enabling the second connecting member 212 to stably slide along the two first sliding grooves 2111, with a stable structure.

[0087] Referring to Figure 8 , 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 slider 2131 slidably connected to the second sliding groove 2123. An end of the second slider 2131 is provided with a second threaded hole 2132. 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 larger than the width of the second sliding groove 2123, and the nut of the second screw abuts against the second connecting member 212, so that the second slider 2131 is stably slidably connected to the second sliding groove 2123.

[0088] Specifically, the second connecting member 212 is provided with one second sliding groove 2123, and the third connecting member 213 is symmetrically provided with two second sliders 2131. Both second sliders 2131 are slidably connected to the second sliding groove 2123, so that the third connecting member 213 can stably slide along the second sliding groove 2123, and the structure is stable.

[0089] Referring to Figure 8 , the mounting seat 240 is mounted on the middle part of the third connecting member 213. Specifically, a slot (not shown in the figure) is provided in the middle part of the third connecting member 213, and the connecting shaft 242 of the mounting seat 240 is adaptively inserted into the slot and fixedly connected to the third connecting member 213.

[0090] In some embodiments, referring to Figure 8 , a third threaded hole 2133 communicating with the slot is provided on the side wall of the third connecting member 213. A third screw (not shown in the figure) is threadedly connected to the third threaded hole 2133. When the third screw is tightened, the screw rod of the third screw presses against the connecting shaft 242, so that the mounting seat 240 is fixedly connected to the third connecting member 213, which is convenient for installation and can replace different types of clamping members 220 at the same time.

[0091] In other embodiments, the connecting shaft 242 can be fixedly inserted into the slot by interference fit, snap connection, bonding or other means, which is convenient for installation.

[0092] 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 clamping members 220, resulting in the unlocking and locking knob being eccentrically clamped between the two clamping members 220. 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 second gear 320 drives the unlocking and locking knob clamped between the two clamping members 220 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, so that the axis of the unlocking and locking knob coincides with the axis of the second gear 320, thus smoothly driving the unlocking and locking knob to rotate without the phenomenon of rotation jamming. At the same time, regardless of whether the unlocking and locking knob is accurately clamped at the exact center position between the two clamping members 220, the installation is convenient.

[0093] In another embodiment of the present invention, referring to Figure 9 , the connecting main member 210 includes a first connecting member 211, a second connecting member 212, and a third connecting member 213.

Specifically, the second gear 320 is at least provided with a fourth chute 3211, and the first connecting member 211 is at least provided with a fourth slider 2112 slidably connected to the fourth chute 3211. The end of the fourth slider 2112 is provided with a fourth threaded hole 2113, and a fourth screw (not shown in the figure) is threadedly connected to the fourth threaded hole 2113. The diameter of the nut of the fourth screw is greater than the width of the fourth chute 3211, and the nut of the fourth screw is close to the end wall of the first gear shaft 321, so that the fourth slider 2112 is stably slidably connected to the fourth chute 3211.

[0094] Specifically, the second gear 320 is symmetrically provided with two fourth chutes 3211. Correspondingly, the first connecting member 211 is symmetrically provided with two fourth sliders 2112, so that the first connecting member 211 can stably slide along the two fourth chutes 3211, and the structure is stable.

[0095] Referring to Figure 9 , the first connecting member 211 is at least provided with a first chute 2111, the first chute 2111 is perpendicular to the fourth chute 3211, and the second connecting member 212 is at least provided with a first slider 2121 slidably connected to the first chute 2111. The end of the first slider 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 chute 2111, and the nut of the first screw is close to the first connecting member 211, so that the first slider 2121 is stably slidably connected to the first chute 2111.

[0096] Specifically, the first connecting member 211 is provided with a first sliding groove 2111, and the second connecting member 212 is symmetrically provided with two first sliders 2121. The two first sliders 2121 are both slidably connected to the first sliding groove 2111, so that the second connecting member 212 can stably slide along the first sliding groove 2111, and the structure is stable.

[0097] Reference Figure 9 The second connecting member 212 is provided with at least one second sliding groove 2123 extending therethrough. The second sliding groove 2123 is arranged parallel to and perpendicular to the first sliding groove 2111. The third connecting member 213 is provided with at least one second slider 2131 slidably connected to the second sliding groove 2123. A second threaded hole 2132 is provided at the end of the second slider 2131. A second screw (not shown) is threadedly connected to the second threaded hole 2132. The diameter of the nut of the second screw is larger 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 slider 2131 is stably slidably connected to the second sliding groove 2123.

[0098] Specifically, the second connecting member 212 is symmetrically provided with two second sliding grooves 2123 , and correspondingly, the third connecting member 213 is symmetrically provided with two second sliding blocks 2131 , so that the third connecting member 213 can stably slide along the two second sliding grooves 2123 , and the structure is stable.

[0099] 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 center position of the two clamping members 220, so that the unlocking and locking knob is eccentrically clamped between the two clamping members 220, the first connecting member 211 is configured to be slidably connected to the second gear 320, the second connecting member 212 is configured to be slidably connected to the first connecting member 211, and the third connecting member 213 is configured to be slidably connected to the second connecting member 212. Therefore, when the second gear 320 passes through the first connecting member, the third connecting member 213 is configured to be slidably connected to the second gear 320. When the connecting member 211, the second connecting member 212 and the third connecting member 213 drive the opening and closing lock knob held between the two clamping members 220 to rotate, the first connecting member 211, the second connecting member 212 and the third connecting member 213 can slide and adjust the position so that the axis of the opening and closing lock knob coincides with the axis of the second gear 320, thereby smoothly driving the opening and closing lock knob to rotate without rotation jamming, and the movement is smoother. At the same time, there is no need to consider whether the opening and closing lock knob is accurately clamped in the center position of the two clamping members 220, and the installation is convenient.

[0100] In another embodiment of the present invention, referring to Figure 13 、 Figure 14 and Figure 15, the unlocking and locking robot further includes a height adjustment mechanism 600. The height adjustment mechanism 600 and the connection mechanism 200 are installed on the same side of the housing main body 100. The distance between the connection mechanism 200 and the unlocking and locking knob of the anti-theft lock is adjusted through the height adjustment mechanism 600, so that the connection mechanism 200 can be connected to the unlocking and locking knob of the anti-theft lock at a suitable position.

[0101] Referring to Figure 13 , Figure 14 and Figure 15 , the height adjustment mechanism 600 includes a plurality of connection blocks 610. Third sliders 611 and third chutes 612 that cooperate with each other are respectively provided at both ends of the connection block 610. A convex card 613 and a card slot 614 that are engaged with each other are provided between the third sliders 611 and the third chutes 612 of two adjacent connection blocks 610, so that the plurality of connection blocks 610 can be sequentially engaged with each other. One connection block 610 is connected to the housing main body 100. The connection blocks 610 are detachably and fixedly connected to each other through the convex cards 613 and the card slots 614 that cooperate with each other. By connecting different numbers or different heights of connection blocks 610 to the housing main body 100, the height of the unlocking and locking robot is adjusted, so that the unlocking and locking robot can be adapted to anti-theft locks of different sizes, with high adaptability. Then, the connection block 610 is fixedly installed on the door or the lock through double-sided tape, 3M tape or screws, etc., so that the unlocking and locking robot is convenient to install and firmly connected.

[0102] Specifically, both the third chute 612 and the third slider 611 are in an inverted T shape, and the third slider 611 is slidably connected to the third chute 612 from an opening at one end of the third chute 612, which is convenient for installation.

[0103] Among them, referring to Figure 13 , Figure 14 and Figure 15 , the convex card 613 and the card slot 614 are respectively installed on the third chute 612 and the third slider 611. When the third slider 611 is installed in the third chute 612, the convex card 613 is fitted and engaged in the card slot 614.

[0104] Preferably, referring to Figure 13 , Figure 14 and Figure 15 , a blocking block 6121 is provided at the opening at the other end of the third chute 612. The third slider 611 is slidably installed in the third chute 612 from an opening at one end of the third chute 612. When the end of the third slider 611 abuts against the blocking block 6121, the convex card 613 is just engaged in the card slot 614, playing a limiting role.

[0105] Furthermore, referring to Figure 13 , Figure 14 and Figure 15, on both sides of the front end of the third slider 611 (the end where the third slider 611 first enters the third chute 613 through the opening at one end of the third chute 612), there are second rounded corners 6111, which facilitate the insertion of the front end of the third slider 611 into the opening at one end of the third chute 612, and facilitate the quick snap connection of the two connecting blocks 610.

[0106] Further, referring to Figure 13 , Figure 14 and Figure 15 , the convex 613 is installed on the elastic plate 615, and by manually bending the elastic plate 615 with an external force, the convex 613 can be disengaged from the engagement with the card slot 614. One end of the elastic plate 615 is connected to the bottom of the third chute 612, and clearance spaces 616 are provided above and below the connecting block 610 with respect to the elastic plate 615. The clearance spaces 616 provide a clearance space when the elastic plate 615 is bent downward, so that when the elastic plate 615 elastically bends downward, it can drive the convex 613 away from the card slot 614, thereby disengaging the convex 613 from the engagement with the card slot 614. At this time, the two connecting blocks 610 can be removed and separated. When the external force is removed, the elastic plate 615 can elastically reset and drive the convex 613 to reset.

[0107] In some embodiments, the heights of multiple connecting blocks 610 are the same.

[0108] In other embodiments, the heights of multiple connecting blocks 610 are different, so that the height of the unlocking and locking robot can be better adjusted to different parameters, and the adaptability is better.

[0109] It can be understood that the set height of the connecting block 610 can be determined according to actual production requirements, and this embodiment does not limit it here.

[0110] In some embodiments, referring to Figure 13 , Figure 14 and Figure 15 , a card slot structure 150 similar to the third chute 612, elastic plate 615 and convex 613 of the connecting block 610 is provided at the bottom of the housing main body 100 close to the connecting block 610. The chute of the card slot structure 150 is adaptively connected to the third slider 611 of the connecting block 610, and the convex 613 of the card slot structure 150 is engaged and connected with the card slot 614 of the connecting block, so that the connecting block 610 is detachably and fixedly connected to the housing main body 100.

[0111] In other embodiments, referring to Figure 14 , Figure 15 and Figure 16, at the bottom of the shell main body 100 close to the connection block 610, there is a first convex structure 160 identical to the third slider 611 and the card slot 614 of the connection block. The slider of the first convex structure 160 is adaptively connected to the third chute 612 of the connection block, and the card slot of the first convex structure 160 cooperates with the convex 613 of the connection block 610 for snap connection, so that the connection block 610 is detachably and fixedly connected to the shell main body 100.

[0112] In another embodiment of the present invention, referring to Figure 17 , the height adjustment 600 further includes a connection seat 620. One end of the connection seat 620 is provided with a second convex structure 621 identical to the third slider 611 and the card slot 614 of the connection block 610. The slider of the second convex structure 621 is adaptively connected to the third chute 612 of the connection block 610, and the card slot of the second convex structure 621 cooperates with the convex 613 of the connection block 610 for snap connection, so that the connection seat 620 is detachably and fixedly connected to the connection block 610.

[0113] Referring to Figure 13 and Figure 17 , the other end of the connection seat 620 is an installation plane. The installation plane is fixedly installed on the door or the anti-theft lock by means of 3M glue, double-sided glue, glue, etc., and the installation is convenient.

[0114] The rest of this embodiment is the same as that 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.

[0115] 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 belongs, without departing from the concept of the present invention, its architecture form can be flexible and variable, and a series of products can be derived. Just making several simple deductions or replacements should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
