[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, a rotary drive device for switching locks includes a housing 1, a mounting bracket 2 fixedly installed inside the housing 1, a circuit board 3, a drive motor 4 and a transmission mechanism are provided on the mounting bracket 2, the drive motor 4 is electrically connected to the circuit board 3, the drive motor 4 is a coreless motor, the coreless motor has an external rotor and a non-locking structure, so the output shaft of the drive motor 4 can be rotated by external force without affecting the internal structure of the motor.

[0026] The housing 1 is equipped with a rotatable unlocking component, which is used to connect to the door lock. The unlocking or locking function is achieved by driving the unlocking component to rotate. The output end of the drive motor 4 is connected to the transmission mechanism, and the output end of the transmission mechanism is connected to the unlocking component. The drive motor 4 can drive the unlocking component to rotate. In use, the circuit board 3 controls the operation of the drive motor 4, which drives the transmission mechanism to move. The transmission mechanism then drives the unlocking component to rotate, thereby achieving the function of automatic unlocking or automatic locking.

[0027] The unlocking assembly includes a clamping mechanism and a knob 5. The clamping mechanism connects to the door lock, and the knob 5 connects to the clamping mechanism, with one end of the knob 5 extending out of the housing 1. The knob 5 drives the clamping mechanism to rotate. During automatic locking / unlocking, the drive motor 4 drives the transmission mechanism, which in turn rotates the clamping mechanism, causing the lock cylinder of the door lock to rotate, thus achieving automatic unlocking or locking. When manual locking / unlocking is required, the user can hold the knob 5 and rotate it. The knob 5 rotates the clamping mechanism, thus unlocking or locking. During the rotation of the knob 5, the transmission mechanism also moves, causing the output shaft of the drive motor 4 to rotate. Because the drive motor 4 is a coreless motor, rotating the knob 5 easily rotates the motor's output shaft without requiring much force, and there is no need to worry about motor wear or damage.

[0028] The rotation driving device for the switch lock can realize the automatic switch lock function while retaining the manual switch lock function without setting the clutch mechanism and the relay and other electrical devices, simplifies the mechanical structure, reduces the manufacturing cost, and reduces the overall size, thereby facilitating the installation and reducing the installation difficulty.

[0029] It should be noted that the present embodiment is not limited to the door lock, and can also be applied to other occasions requiring rotation driving, and the utility model is not limited thereto; for example, a toilet with a rotary switch can be modified into an automatic flushing toilet by using the present embodiment.

[0030] In order to improve the driving force, the speed reducer 6 is further arranged on the mounting frame 2, the gear set is arranged in the speed reducer 6, the input end of the speed reducer 6 is connected with the output end of the driving motor 4, and the output end of the speed reducer 6 is connected with the transmission mechanism. The speed reducer 6 can reduce the rotating speed and increase the torque, so that the transmission mechanism can drive the clamping mechanism to rotate and realize the automatic lock opening or closing function. The speed reducer 6 can increase the driving force of the driving motor 4, so as to ensure that the clamping mechanism can be stably driven to rotate and improve the stability of the work.

[0031] The transmission mechanism comprises a first gear 7, a second gear 8 and a third gear 9. The first gear 7 is connected with the output end of the speed reducer 6, the second gear 8 is rotatably connected with the mounting frame 2, the third gear 9 is rotatably connected with the clamping mechanism and the rotation, and the second gear 8 is meshingly connected with the first gear 7 and the third gear 9. When the driving motor 4 works, the driving motor 4 drives the speed reducer 6 to work, the speed reducer 6 drives the first gear 7 to rotate, the first gear 7 drives the second gear 8 to rotate, the second gear 8 drives the third gear 9 to rotate, and the third gear 9 drives the clamping mechanism to rotate, so as to drive the lock cylinder of the door lock to rotate and realize the lock opening or closing function.

[0032] The first gear 7, the second gear 8 and the third gear 9 can further reduce the rotating speed of the driving motor 4 and further improve the driving force. Meanwhile, the shaft center of the driving motor 4 and the shaft center of the clamping mechanism can not be on a straight line, so as to facilitate the internal structure layout of the product, further reduce the size of the product and improve the aesthetic degree of the product.

[0033] In order to supply power to the rotation driving device, the battery box 10 is arranged on the mounting frame 2, the battery box 10 can be used for installing the battery 11, the battery box 10 is electrically connected with the circuit board 3, and the detachable battery cover 12 is arranged at the position corresponding to the battery box 10 on the shell 1. The battery 11 in the battery box 10 can be conveniently installed or removed by opening the battery cover 12. In use, the battery 11 in the battery box 10 supplies power to the circuit board 3, so that the circuit board 3 can control the driving motor 4 to work and realize the automatic lock opening or closing function.

[0034] The front end surface of the shell 1 is provided with an unlocking button 13 and a locking button 14, which are electrically connected with the circuit board 3. During use, the user presses the unlocking button 13 or the locking button 14 to send a corresponding control signal to the circuit board 3, and the circuit board 3 controls the driving motor 4 to rotate forward or reverse, thereby driving the clamping mechanism to rotate and realizing the functions of automatic unlocking and locking. By arranging the unlocking button 13 and the locking button 14, the user can manually rotate the knob 5 to realize the functions of unlocking and locking, or press the corresponding button to realize the function of one-key unlocking and locking, thereby improving the functionality and convenience.

[0035] The clamping mechanism includes a mounting seat 15 fixedly connected with the third gear 9, and two clamping jaws 16 are arranged on the mounting seat 15. The two clamping jaws 16 can clamp the lock cylinder of the door lock, so that the rotation of the two clamping jaws 16 can drive the rotation of the lock cylinder of the door lock, thereby realizing the functions of unlocking and locking.

[0036] In this embodiment, soft rubber pads 17 are arranged on the two clamping jaws 16 respectively. The arrangement of the soft rubber pads 17 can make the clamping jaws 16 stably clamp the lock cylinder of the door lock, thereby avoiding the situation of slipping. At the same time, the soft rubber pads 17 also make the clamping jaws 16 softly contact the lock cylinder of the door lock, thereby avoiding the situation of scratching or damaging the door lock, and improving the practicability.

[0037] In order to be suitable for different types of door locks, the clamping jaws 16 and the mounting seat 15 are connected in a slidable and limited manner. The mounting seat 15 is provided with an adjusting mechanism, the adjusting mechanism is connected with the clamping jaws 16 respectively, and the adjusting mechanism can drive the two clamping jaws 16 to move close to or away from each other. The arrangement of the adjusting mechanism facilitates the clamping and fixing of the clamping jaws 16 and the lock cylinder of the door lock. At the same time, the adjusting mechanism adjusts the distance between the two clamping jaws 16, so that the rotary driving device can be suitable for the use requirements of lock cylinders of different sizes, thereby improving the versatility.

[0038] Specifically, the adjusting mechanism includes a bidirectional screw rod 18, which is rotatably connected with the mounting seat 15. The two ends of the bidirectional screw rod 18 extend out of the end surface of the mounting seat 15, and the two end surfaces of the bidirectional screw rod 18 are respectively provided with cross grooves 19. The two clamping jaws 16 are threadedly connected with the bidirectional screw rod 18. When it is necessary to adjust the distance between the two clamping jaws 16, a cross screwdriver can be inserted into the cross groove 19, and the bidirectional screw rod 18 can be driven to rotate by rotating the screwdriver, thereby driving the two clamping jaws 16 to slide on the mounting seat 15, so that the two clamping jaws 16 move close to or away from each other.

[0039] In other embodiments, the end surface of the bidirectional screw rod 18 can also be provided with a groove suitable for other common tools, such as a slot groove or a hexagonal groove.

[0040] In order to limit and guide the sliding direction of the clamping jaw 16 on the mounting seat 15, a guide sliding groove 20 is arranged on the mounting seat 15, and a clamping block 21 is arranged on the clamping jaw 16, which is in sliding clamping connection with the guide sliding groove 20. During the rotation of the bidirectional screw rod 18, the clamping jaw 16 will slide on the bidirectional screw rod 18, and the clamping block 21 will also slide in the guide sliding groove 20. Through the cooperation of the clamping block 21 and the guide sliding groove 20, the sliding direction of the clamping jaw 16 can be limited and guided, thereby improving the stability and accuracy of the adjustment.

[0041] The rotating driving device for opening and closing the lock further comprises an adjusting support 22, which is in slidable limiting connection with the shell 1. One end of the adjusting support 22 extends into the shell 1 and is fixedly connected with the mounting frame 2, and the other end extends out of the shell 1. The adjusting support 22 is used to thicken the rear end of the shell 1, so that it is suitable for the installation requirements of different door locks. In the specific use process, if the panel of the door lock is relatively thick, the adjusting support 22 can be pulled out of the shell 1, thereby increasing the thickness of the rear end of the shell 1, so that it can be installed on the corresponding door lock, and it is ensured that the clamping jaw 16 can clamp the lock cylinder on the door lock. On the contrary, if the panel of the door lock is relatively thin, the adjusting support 22 can be pushed into the shell 1, so that the clamping jaw 16 can be aligned and clamped with the lock cylinder of the door lock.

[0042] In order to facilitate adjustment, a plurality of connecting holes 23 are arranged at equal intervals on the adjusting support 22 in the embodiment, and a connecting screw 24 is arranged on the shell 1. The connecting screw 24 can pass through the connecting holes 23 and be detachably connected with the mounting frame 2. Under normal circumstances, one end of the adjusting support 22 provided with the connecting holes 23 extends into the shell 1, and the connecting screw 24 is fixedly connected with the mounting frame 2 after passing through a group of connecting holes 23, so that the adjusting support 22 is limitingly fixed with the shell 1. When adjustment is needed, the connecting screw 24 can be loosened, and then the adjusting support 22 can be pulled out of or pushed into the shell 1. After adjustment to the appropriate position, the connecting screw 24 is passed through the corresponding connecting hole 23 and is re-tightened and connected with the mounting frame 2. By changing the length of the adjusting support 22 extending out of the shell 1, the thickness of the rear end of the shell 1 is changed, so that it is suitable for the installation requirements of different door locks, and the universality is improved.

[0043] Working principle:

[0044] First, the rotating driving device for opening and closing the lock is installed at a predetermined position, the clamping jaw 16 is clamped and fixed with the lock cylinder of the door lock by rotating the bidirectional screw rod 18, and the circuit board 3 is connected with an external control terminal, which can be a card swiping device, a smart phone, etc.

[0045] When the user needs to open or close the lock outside the door, the user can operate the control terminal, the control terminal sends a control signal to the circuit board 3, the circuit board 3 controls the driving motor 4 to work, the driving motor 4 drives the speed reducer 6 to work, the speed reducer 6 drives the first gear 7 to rotate, the first gear 7 drives the second gear 8 to rotate, the second gear 8 drives the third gear 9 to rotate, the third gear 9 drives the clamping jaw 16 to rotate, thereby driving the lock core of the door lock to rotate, and the function of automatically opening or closing the lock is realized.

[0046] When the user needs to open or close the lock inside the door, the user can press the opening button 13 or the closing button 14, and when the opening button 13 or the closing button 14 is pressed, the working process of the rotating driving device for opening or closing the lock is the same as the process of the control terminal controlling the opening or closing of the lock, and the process is not repeated here. On the other hand, the user can also manually rotate the knob 5 to open or close the lock inside the door, and after the user rotates the knob 5, the knob 5 drives the clamping jaw 16 to rotate, thereby realizing the opening or closing of the lock; in the process of rotating the knob 5, the third gear 9 is also driven to rotate, the third gear 9 drives the second gear 8 and the first gear 7 to rotate, and the first gear 7 drives the output shaft of the driving motor 4 and the speed reducer 6 to rotate. Because the driving motor 4 is a hollow cup motor, rotating the knob 5 can easily drive the output shaft of the motor to rotate, without the need for a large force, and there is no need to worry about the problem of motor wear or damage.

[0047] When it is necessary to adjust the distance between the two clamping jaws 16, a cross screwdriver can be inserted into the cross groove 19, and by rotating the screwdriver, the bidirectional screw rod 18 can be driven to rotate, thereby driving the two clamping jaws 16 to slide on the mounting seat 15, so that the two clamping jaws 16 approach or move away from each other, and the purpose of adjusting the distance between the clamping jaws 16 is achieved, so that it is suitable for use with different types of door locks.
