[0002] The door opener is a driving device of an automatic door, and is used for realizing electric opening and closing of a door body. The door opener mainly comprises a driving motor, a transmission device and a clutch device. When the clutch device is in a closed state, the clutch device is in transmission connection with the driving motor and the transmission device, so that power of the driving motor is transmitted to the transmission device, and then the transmission device drives the door body to open or close. When power is cut off or the driving motor is faulty, the clutch device is opened, so that the driving motor and the transmission device are disconnected, and then the door body can be manually opened or closed by an operator.

[0003] In the related art, the opening and closing of the clutch device is generally realized by using a wrench. Specifically, the wrench is rotatably arranged on a fixed seat of the door opener, and is connected with the clutch device through a transmission assembly. The wrench can be rotated to drive the clutch device to move through the transmission assembly, so as to manually open and close the clutch device. In order to avoid the wrench being randomly rotated, the wrench is embedded in the fixed seat or hidden in the related art. In one way, the fixed seat is provided with a mounting groove, the wrench is embedded in the mounting groove, and the fixed seat is provided with a lock control device to lock the wrench in the mounting groove. When the opening and closing of the clutch device is needed, the user can use a key to unlock the lock control device, so that the wrench is automatically popped out of the mounting groove. At this time, the user can rotate the wrench to realize the opening and closing of the clutch device. In this way, the operation is complex, and the connection structure of the lock control device and the wrench is complex. In another way, an outer shell is arranged outside the fixed seat, so that the outer shell covers the wrench, and the wrench is hidden. In this way, when the clutch operation is performed, the outer shell needs to be disassembled before the wrench is rotated. The operation is complex.

[0004] Therefore, the manual opening and closing of the clutch device in the related art has the defects of complex operation and complex structure. INVENTION CONTENTS

[0005] The purpose of the embodiments of the application is to provide a lock control device of a clutch device, a clutch device and a door opener, which can solve the problem of complex operation and complex structure of the manual opening and closing of the clutch device in the related art.

[0006] In a first aspect, the embodiments of the application provide a lock control device of a clutch device, comprising:

[0007] A lock cylinder sleeve is arranged rotatably in a fixed seat of a door opener.

[0008] The lock core is arranged in the lock core sleeve and is in sliding connection with the lock core sleeve.

[0009] The key is connected with the lock core sleeve and is used to drive the rotation of the lock core sleeve. When the lock core sleeve rotates, the lock core slides along the axial direction of the lock core sleeve to drive the opening and closing of the clutch.

[0010] In a second aspect, the embodiments of the present application further provide a clutch device, comprising a clutch and the lock control device of the clutch device. The lock core of the lock control device is connected with the clutch to drive the opening and closing of the clutch.

[0011] In a third aspect, the embodiments of the present application further provide a door opener, comprising a fixed seat, a driving motor, a transmission device and the clutch device. The driving motor and the clutch device are arranged in the fixed seat. The transmission device is used to be connected with a door body. When the clutch of the clutch device is closed, the driving motor is in transmission connection with the transmission device through the clutch.

[0012] In the embodiments of the present application, the lock core sleeve is rotatably arranged in the fixed seat of the door opener. The lock core is arranged in the lock core sleeve and is in sliding connection with the lock core sleeve. The key is connected with the lock core sleeve and is used to drive the rotation of the lock core sleeve. When the opening and closing operation of the clutch is needed, the key is connected with the lock core sleeve and is rotated to drive the rotation of the lock core sleeve. Then, the lock core slides along the axial direction of the lock core sleeve to drive the opening and closing of the clutch. In this way, the operation is simple and convenient. Meanwhile, the opening and closing of the clutch can be realized directly through the movement of the lock core. The structure of the lock control device is simple.

[0026] The technical solutions in the embodiments of the present application will be described clearly in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0027] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0028] The lock control device of the clutch device, the clutch device and the door opener provided by the embodiments of the present application will be described in detail below in combination with the drawings through specific embodiments and application scenarios.

[0029] Reference Figures 1-7 The locking control device of the clutch device provided by the embodiments of the present application can include a lock cylinder sleeve 300, a lock cylinder 400, and a key 500. The lock cylinder sleeve 300 can be rotatably arranged in a fixed seat 100 of a door opener. The lock cylinder 400 can be used to drive the opening and closing of a clutch of the clutch device. The lock cylinder 400 can be arranged in the lock cylinder sleeve 300 and is in sliding connection with the lock cylinder sleeve 300. The key 500 can be connected with the lock cylinder sleeve 300. The key 500 can be used to drive the rotation of the lock cylinder sleeve 300. That is, the rotation of the key 500 can drive the synchronous rotation of the lock cylinder sleeve 300. When the lock cylinder sleeve 300 rotates, the lock cylinder 400 can slide along the axial direction of the lock cylinder sleeve 300 to drive the opening and closing of the clutch.

[0030] When the opening and closing operation of the clutch is needed, the key 500 can be connected with the lock cylinder sleeve 300 and rotated to drive the rotation of the lock cylinder sleeve 300, and then the lock cylinder 400 can slide along the axial direction of the lock cylinder sleeve 300 to drive the opening and closing of the clutch. In this way, the key 500 only needs to be slightly rotated to realize the accurate opening and closing of the clutch, and the operation is simple and convenient. Meanwhile, the opening and closing of the clutch can be realized directly through the movement of the lock cylinder 400, so that the structure of the locking control device is simple. Since the lock cylinder sleeve 300 is arranged in the fixed seat 100, the lock cylinder sleeve 300 is not easy to be randomly operated to drive the opening and closing of the clutch, and the dust or rainwater from the outside is not easy to enter the fixed seat 100, so that the dustproof and waterproof effect of the door opener can be improved.

[0031] It should be noted that the lock cylinder sleeve 300 can be in sealing cooperation with the fixed seat 100. In this way, the dust or rainwater from the outside can be prevented from entering the inside of the fixed seat 100 through the locking control device to adversely affect the devices or components in the inside of the fixed seat 100.

[0032] In the optional embodiments of the present application, one of the lock cylinder sleeve 300 and the lock cylinder 400 can be provided with a first sliding groove 340, and the other can be provided with a positioning pin 410. The positioning pin 410 can be located in the first sliding groove 340 and can slide relative to the first sliding groove 340. Here, the first sliding groove 340 can be spirally arranged along the axial direction of the lock cylinder sleeve 300. In this way, through the cooperation of the positioning pin 410 and the first sliding groove 340, the rotation of the lock cylinder sleeve 300 can be converted into the movement of the lock cylinder 400 to drive the opening and closing of the clutch.

[0033] Here, the first sliding groove 340 is matched with the positioning pin 410 to convert the rotation of the lock cylinder sleeve 300 into the movement of the lock cylinder 400, which does not need to open multiple threads on the inner wall of the lock cylinder sleeve 300 and does not need to set multiple external threads on the outer wall of the lock cylinder 400, facilitating processing. In addition, the positioning pin 410 can also be in sliding connection with the fixed seat 100, thereby playing a role in limiting the rotation of the lock cylinder 400.

[0034] In other embodiments, the lock cylinder sleeve 300 and the lock cylinder 400 are in threaded connection to be able to convert the rotation of the lock cylinder sleeve 300 into the rotation and movement of the lock cylinder 400.

[0035] In optional embodiments, the lock cylinder sleeve 300 can be provided with the first sliding groove 340, the lock cylinder 400 can be provided with the positioning pin 410, and one end of the positioning pin 410 can pass through the first sliding groove 340 and be in slidable connection with the fixed seat 100. In this way, through the sliding connection of the positioning pin 410 and the fixed seat 100, the lock cylinder 400 can only slide along the axial direction of the lock cylinder sleeve 300 without rotating, thereby avoiding the mutual abrasion between the lock cylinder 400 and the clutch caused by the rotation of the lock cylinder 400 or avoiding the rotation of the clutch caused by the rotation of the lock cylinder 400. Here, the first sliding groove 340 can be a through groove passing through the cylinder wall of the lock cylinder sleeve 300.

[0036] It should be noted that the first sliding groove 340 can surround the lock cylinder sleeve 300 by 180°, so that when the key 500 is rotated, the key 500 does not need to be rotated in a full circle, facilitating operation. Of course, the first sliding groove 340 can also surround the lock cylinder sleeve 300 by 360°.

[0037] In the embodiments of the present application, the positioning pin 410 is arranged on the lock cylinder 400, and the first sliding groove 340 is arranged on the lock cylinder sleeve 300. Compared with the arrangement mode that the positioning pin 410 is arranged on the lock cylinder sleeve 300 and the first sliding groove 340 is arranged on the lock cylinder 400, the arrangement mode is convenient for processing and installation.

[0038] In other embodiments, the positioning pin 410 can also be arranged on the lock cylinder sleeve 300, and the first sliding groove 340 can also be arranged on the lock cylinder 400. One end of the positioning pin 410 can protrude from the inner wall surface of the lock cylinder sleeve 300 and extend into the first sliding groove 340, and the other end of the positioning pin 410 can protrude from the outer wall surface of the lock cylinder sleeve 300 and be in sliding connection with the fixed seat 100.

[0039] In an optional embodiment, one of the lock cylinder sleeve 300 and the lock cylinder 400 can be provided with a first limiting slot 350, the first limiting slot 350 can extend along the circumference of the lock cylinder sleeve 300, the first limiting slot 350 can be in communication with the first sliding slot 340, and the first limiting slot 350 can be located at one end of the first sliding slot 340 close to the clutch.

[0040] Wherein, in the case that the lock cylinder 400 drives the clutch to open, the positioning pin 410 is located in the first limiting slot 350, and the positioning pin 410 is in limiting cooperation with the first limiting slot 350 in the axial direction of the lock cylinder sleeve 300. In this way, the lock cylinder 400 and the lock cylinder sleeve 300 can be in a relatively static state, so that the lock cylinder 400 no longer moves, so that the clutch remains in the open state, and it is ensured that the clutch function will not fail when manually opening the door body.

[0041] Of course, one of the lock cylinder sleeve 300 and the lock cylinder 400 can also not be provided with the first limiting slot 350.

[0042] In an optional embodiment, one of the lock cylinder sleeve 300 and the lock cylinder 400 can also be provided with a second limiting slot 360, the second limiting slot 360 can extend along the circumference of the lock cylinder sleeve 300, the second limiting slot 360 can be in communication with the first sliding slot 340, and the second limiting slot 360 can be located at one end of the first sliding slot 340 away from the clutch.

[0043] Wherein, in the case that the clutch is in the closed state, the positioning pin 410 is located in the second limiting slot 360, and the positioning pin 410 is in limiting cooperation with the second limiting slot 360 in the axial direction of the lock cylinder sleeve 300. In this way, the lock cylinder 400 and the lock cylinder sleeve 300 can be in a relatively static state, so that the lock cylinder 400 no longer moves, so that the clutch can be prevented from being separated under non-human conditions, so that the clutch remains in the closed state.

[0044] Of course, one of the lock cylinder sleeve 300 and the lock cylinder 400 can also not be provided with the second limiting slot 360.

[0045] In the embodiments of the present application, through the limiting cooperation of the first limiting slot 350 and the second limiting slot 360 with the lock cylinder 400, the clutch can have a locking function in the open state and the closed state, ensuring the stability and safety of the clutch function under unauthorized operation, and effectively avoiding clutch function failure due to non-human factors.

[0046] In optional embodiments, the lock cylinder sleeve 300 can include a sleeve body 310 and a key connecting portion 320, the sleeve body 310 can be located in the fixed seat 100, the key connecting portion 320 can be connected with the sleeve body 310 away from the clutch, and the key connecting portion 320 can be used for connecting with the key 500 to facilitate the key 500 driving the lock cylinder sleeve 300 to rotate.

[0047] Optionally, a limiting plate 330 can be arranged on the key connecting portion 320, and the key 500 can be limited and matched with the limiting plate 330 in the direction of the key connecting portion 320 to the sleeve body 310, so as to be positioned for the key 500.

[0048] Of course, the limiting plate 330 can also not be arranged on the key connecting portion 320.

[0049] In some embodiments, the key 500 can be provided with a connecting hole, and the key connecting portion 320 can be embedded in the connecting hole to realize the connection of the key 500 and the key connecting portion 320. And the connecting hole and the key connecting portion 320 can be limited and matched in the circumferential direction of the key connecting portion 320, so that the key 500 can drive the key connecting portion 320 to rotate.

[0050] Optionally, a first limiting plane can be arranged on the hole wall of the connecting hole, and a second limiting plane can be arranged on the key connecting portion 320, and the first limiting plane and the second limiting plane can be limited and matched in the circumferential direction of the key connecting portion 320. Alternatively, the shape of the cross section of the connecting hole can be polygonal, the shape of the cross section of the key connecting portion 320 can be polygonal, and the shapes of the cross sections of the connecting hole and the key connecting portion 320 are consistent. Here, the connecting hole can be a square hole, and the key connecting portion 320 can be a cuboid structure.

[0051] Based on the clutch device provided in the embodiments of the present application, the embodiments of the present application further provide a lock control device of the clutch and the clutch device, and the lock core 400 of the lock control device can be connected with the clutch to drive the clutch to open and close.

[0052] The beneficial effects achieved by the clutch device provided in the embodiments of the present application are consistent with the beneficial effects achieved by the lock control device of the clutch and the clutch device provided in the embodiments of the present application, and therefore will not be described here.

[0053] In optional embodiments of the present application, the clutching device can further include a clutching push plate 200 and an elastic member. The clutching push plate 200 can be slidably arranged on the fixed seat 100 of the door opener, a first end of the clutching push plate 200 is connected with the clutch, and a second end of the clutching push plate 200 can be connected with the lock cylinder 400. Specifically, the second end of the clutching push plate 200 can be in contact with the lock cylinder 400, and the lock cylinder 400 can push the clutching push plate 200 to move to the first position to make the clutch open. A first end of the elastic member can be connected with the fixed seat 100, and the other end of the elastic member can be connected with the clutching push plate 200. The elastic member can be used to drive the clutching push plate 200 to move from the first position to the second position. Here, the elastic member can be a spring.

[0054] Wherein, when the clutching push plate 200 is at the first position, the clutch is in an open state, at this time, the clutch is disconnected with the drive motor and the transmission device of the door opener respectively, and the user can manually open or close the door body.

[0055] When the clutching push plate 200 is at the second position, the clutch is in a closed state, at this time, the clutch is in driving connection with the drive motor and the transmission device of the door opener respectively, and the drive motor can drive the door body to automatically open or close.

[0056] The way of using the elastic member to drive the clutching push plate 200 to return to the second position, i.e. the way of using the elastic member to drive the clutching push plate 200 to reset, can realize the automatic resetting of the clutching push plate 200, i.e. the automatic closing of the clutch, which is conducive to simplifying the operation, and the lock cylinder 400 and the clutching push plate 200 do not need to be provided with a connecting structure, which is further conducive to simplifying the structure of the clutching device.

[0057] In other embodiments, the clutching device can also not include an elastic member. Specifically, the lock cylinder 400 can be connected with the clutching push plate 200, and the lock cylinder 400 can drive the clutching push plate 200 to reciprocate between the first position and the second position, i.e. the lock cylinder 400 can push the clutching push plate 200 to move to the first position, and the lock cylinder 400 can pull the clutching push plate 200 to move to the second position.

[0058] Optionally, the clutch can be a clutch gear. When the clutch is in a closed state, the clutch gear is in meshing with the drive motor and the transmission device to realize the driving connection of the drive motor and the transmission device.

[0059] In an optional embodiment, in order to avoid the shift of the clutch push plate 200 during the movement, one of the clutch push plate 200 and the fixed seat 100 can be provided with a third limiting groove 210, and the other can be provided with a limiting column 160, the limiting column 160 can be slidingly arranged in the third limiting groove 210, and the extending direction of the third limiting groove 210 can be parallel to the axial direction of the lock core sleeve 300. Here, the limiting column 160 and the third limiting groove 210 are limitedly matched in the direction perpendicular to the axial direction of the lock core sleeve 300, so that the clutch push plate 200 can only move along the axial direction of the lock core sleeve 300, thereby avoiding the shift of the clutch push plate 200 during the movement.

[0060] In the embodiment, the third limiting groove 210 can be arranged on the clutch push plate 200, and the limiting column 160 can be arranged on the fixed seat 100.

[0061] Optionally, in the case that the clutch push plate 200 is located at the first position, the limiting column 160 and the third limiting groove 210 are limitedly matched with the groove wall away from the clutch, which is arranged in such a way that the user can know whether the clutch is opened to the position when the user controls the clutch to be opened, thereby avoiding the user's operation to be not in place.

[0062] In the case that the clutch push plate 200 is located at the second position, the limiting column 160 and the third limiting groove 210 are limitedly matched with the groove wall close to the clutch, which is arranged in such a way that the clutch can be avoided to exceed the closed position when it is returned to the closed position, thereby causing the clutch to be connected to the driving motor and the transmission device.

[0063] Further optionally, one of the clutch push plate 200 and the fixed seat 100 can be provided with at least two third limiting grooves 210, and the other can be provided with at least two limiting columns 160, each limiting column 160 is slidingly arranged in each third limiting groove 210, and each third limiting groove 210 can be arranged in a staggered manner, which can further avoid the shift of the clutch push plate 200 during the movement.

[0064] Based on the door opening machine provided by the embodiments of the present application, the embodiments of the present application further provide a door opening machine, which can include a fixed seat 100, a driving motor, a transmission device, and a clutch device as described in any of the above embodiments. The driving motor and the clutch device can be arranged in the fixed seat 100, and the transmission device can be used to be connected with a door body. When the clutch of the clutch device is in a closed state, the driving motor can be drivingly connected with the transmission device through the clutch.

[0065] The beneficial effects achieved by the door opening machine provided by the embodiments of the present application are consistent with the beneficial effects achieved by the clutch device provided by the embodiments of the present application, which will not be described here.

[0066] In optional embodiments of the present application, the fixing base 100 can be provided with a mounting hole 130, and the lock control device of the clutch device can be arranged in the mounting hole 130. In this way, the lock control device can be avoided from being exposed.

[0067] Optionally, the lock cylinder sleeve 300 of the lock control device can be sealingly matched with the hole wall of the mounting hole 130. In this way, the dust or rainwater from the outside can be avoided from entering the inside of the fixing base 100 through the gap between the lock cylinder sleeve 300 and the hole wall of the mounting hole 130, so as to avoid the adverse effects on the devices or components in the fixing base 100.

[0068] In some embodiments, the fixing base 100 can be provided with a mounting portion 110 and a lock cylinder cover 120 detachably connected with the mounting portion 110. The mounting hole 130 can be formed between the mounting portion 110 and the lock cylinder cover 120.

[0069] Further optionally, the fixing base 100 can be provided with a lock hole 150. The key connecting portion 320 of the lock cylinder sleeve 300 described above can be arranged opposite to the lock hole 150, and the side of the limiting plate 330 away from the key connecting portion 320 can be in contact with the mounting portion 110 and the lock cylinder cover 120, so as to close the end of the mounting hole 130 close to the lock hole 150. In this way, the rainwater or dust can be further avoided from entering the mounting hole 130 and then entering the inside of the fixing base 100 through the mounting hole 130.

[0070] It should be noted that the key 500 can pass through the lock hole 150 to be connected with the key connecting portion 320.

[0071] The lock cylinder 400 of the lock control device can be provided with a positioning pin 410, and the hole wall of the mounting hole 130 can be provided with a second sliding groove 140. The extension direction of the second sliding groove 140 can be parallel to the axial direction of the lock cylinder sleeve 300 of the lock control device, and the positioning pin 410 can be in sliding connection with the second sliding groove 140. In this way, the lock cylinder 400 can only slide along the axial direction of the lock cylinder sleeve 300 without rotating, so as to avoid the mutual abrasion between the lock cylinder 400 and the clutch caused by the rotation of the lock cylinder 400 or avoid the rotation of the clutch caused by the rotation of the lock cylinder 400.

[0072] Of course, the hole wall of the mounting hole 130 can also not be provided with the second sliding groove 140, i.e., the positioning pin 410 is not in sliding connection with the fixing base 100.

[0073] When the power failure or drive motor failure occurs, the key 500 is inserted into the lock hole 150 and connected with the key connecting part 320 of the lock cylinder sleeve 300, and then the key 500 is rotated clockwise to drive the lock cylinder sleeve 300 to rotate clockwise in the mounting hole 130. The positioning pin 410 on the lock cylinder 400 drives the clutch push plate 200 to move away from the lock hole 150. When the key 500 is rotated 180° clockwise, i.e. the lock cylinder sleeve 300 is rotated 180° clockwise, the lock cylinder 400 drives the clutch push plate 200 to move to the first position, and then the clutch is opened, i.e. the clutch is disconnected from the drive motor and the transmission device. At this time, the user can manually open and close the door body. When the lock cylinder sleeve 300 is rotated 180° clockwise, the positioning pin 410 is located in the first limiting groove 350 and limited in the axial direction of the lock cylinder sleeve 300. In this way, the lock cylinder 400 and the lock cylinder sleeve 300 are in a relatively static state, and then the lock cylinder 400 is no longer moved, so that the clutch remains in the open state.

[0074] When the opening or closing of the door body needs to be automatically controlled, the key 500 is inserted into the lock hole 150 and connected with the key connecting part 320 of the lock cylinder sleeve 300, and then the key 500 is rotated counterclockwise to drive the lock cylinder sleeve 300 to rotate counterclockwise in the mounting hole 130. The positioning pin 410 on the lock cylinder 400 moves towards the lock hole 150 under the action of the lock cylinder sleeve 300. At this time, the clutch push plate 200 moves towards the lock hole 150 under the action of the elastic element (as shown in Figure 1 and Figure 2 , the direction of the arrow a is the direction of the elastic force of the elastic element). When the key 500 is rotated 180° counterclockwise, i.e. the lock cylinder sleeve 300 is rotated 180° counterclockwise, the elastic element drives the clutch push plate 200 to move to the second position, and then the clutch is closed, i.e. the clutch is connected with the drive motor and the transmission device. At this time, the drive motor can automatically drive the door body to open or close. When the lock cylinder sleeve 300 is rotated 180° counterclockwise, the positioning pin 410 is located in the second limiting groove 360 and limited in the axial direction of the lock cylinder sleeve 300. In this way, the lock cylinder 400 and the lock cylinder sleeve 300 are in a relatively static state, and then the lock cylinder 400 is no longer moved, so that the clutch remains in the closed state.
