The body 110 is the base of the wedge drive 100 for carrying other components. According to some embodiments of the present application, the body 110 may have a basic shape of a rectangle, a circle, etc. with a certain thickness, which is not limited in the present application. A wedge surface 120 is provided at one side of the body 110; the wedge surface 120 is shaped to be depressed from the outer circumference toward the center. As shown in fig. 2, the wedge surface 120 is configured such that the dimension of the body 110 in the width direction is gradually reduced from the upper and lower ends to the center, forming a wedge shape. Referring to fig. 1, the guide 130 is disposed on the wedge surface 120. According to some embodiments of the present application, the guide 130 may be implemented as a guide groove along the height direction of the body 110. Referring to fig. 2, a transmission member 140 is disposed on the other side of the body 110, and is configured to drive the body 110 to move along the direction of the guide member 130 under the driving of a moving component.

The first transmission member 141 is disposed on the second side of the body 110; the second transmission member 142 is disposed at a third side of the body 110. When the wedge-shaped transmission component is applied to a clutch structure of the lock body, the first transmission member 141 can be engaged with an outer transmission mechanism (such as a key transmission mechanism) to realize the clutch of the lock body; the second transmission member 142 can be engaged with an internal transmission mechanism (e.g., an inner door handle) to realize the clutching of the lock body.

FIG. 3 shows a front view of a clutch arrangement according to an exemplary embodiment of the present application; FIG. 4 shows a side view of a clutch structure according to an example embodiment of the present application.

According to another aspect of the present application, there is also provided a clutch structure 1000 for a lock body, including the wedge driving member 100 described above. Referring to fig. 3 and 4, the clutch structure 1000 includes a wedge-shaped transmission member 100, a guide rod 200, an adaptor member 300, a clutch member 400, and an elastic member 500.

Referring to fig. 4, a wedge driving member 100 is disposed at one end of the guide bar 200, for example, a guide 130 of the wedge driving member 100 may be disposed at one end of the guide bar 200. An adapter member 300 is disposed on the guide bar 200 with one end contacting the wedge surface 120 of the wedge actuating member 100. When the wedge driving member 100 moves down along the guide 130, the adaptor member 300 contacting the wedge surface 120 is pushed to move linearly along the guide bar 200. That is, the up-and-down movement of the wedge transmission member 100 is changed to the left-and-right movement of the adapter member 300 by the engagement of the wedge surface 120 with the adapter member 300. The clutch member 400 is disposed on the guide bar 200, and one end thereof is connected to the other end of the adaptor member 300; under the pushing of the adapting component 300, the clutch component 400 can move left and right along the guide rod 200; the clutch member 400 is linearly moved along the guide bar 200, and is separated from the engaged member after being out of the plane. The elastic member 500 is disposed at the other end of the clutch member 400; when the wedge transmission member 100 pushes the adapting member 300 to move along the guide rod 200, the adapting member 300 further pushes the clutch member 400 to move along the guide rod 200, so that the elastic member 500 is compressed. According to some embodiments of the present application, the clutch structure 1000 includes a fixing member 600 at the other end of the guide bar 200 for fixing the elastic member 500.

According to some embodiments of the present disclosure, the elastic member 500 may be a spring disposed at the outer periphery of the guide bar 200, or may be a solid elastic member coupled to the clutch member 400, and functions to provide a restoring force for the returning of the clutch member 400. According to an example embodiment of the present application, referring to fig. 3, the clutch member 400 may be a first gear engaged with or disengaged from a second gear, thereby implementing the clutch. According to some embodiments of the application, the function of the adapter member 300 is to transmit motion on the one hand and to increase the distance between the wedge transmission member 100 and the clutch member 400 on the other hand, so as to avoid interference of the wedge transmission member 100 with the transmission site of the clutch member 400. For example, the adapter 300 may be a raised element, which may be T-shaped, trapezoidal, rectangular, etc., and the application is not limited thereto.

Figure 5 shows a front view of a lock body according to an exemplary embodiment of the present application; figure 6 shows a side view of a lock body according to an example embodiment of the present application.

According to another aspect of the present application, there is also provided a lock body 2000, as shown in fig. 5 and 6, the lock body 2000 including the clutch structure 1000, the motor 2100, and the reducer 2200 described above. Wherein, the speed reducer 2200 is connected with the motor 2100, and the clutch structure 1000 is connected with the speed reducer 2200. According to an example embodiment of the present application, the reducer 2200 may employ a reduction gear box.

According to an example embodiment of the application, the process of clutching the lock body 2000 through a first side (e.g., the exterior key side) is as follows: the key rotates to drive the first transmission piece 141 on the wedge transmission part 100 to move downwards along the guide piece 130 through the transmission mechanism; the wedge-shaped transmission component 100 pushes the adapter component 300 (such as a block-up piece) in the process of moving downwards; the adaptor member 300 pushes the clutch member 400 (e.g., lock body drive gear) to move along the guide rod 200, thereby moving out of the plane of its engaged position and disengaging from the lock body switch lock gear (not shown); after the key is separated, the lock gear of the lock body is driven to rotate by the key, so that unlocking is realized. During the process that the adaptor member 300 pushes the clutch member 400 to move, the clutch member 400 compresses the elastic member 500.

After unlocking is finished, the key is reversely rotated to drive the wedge-shaped transmission part 100 to move upwards; the clutch member 400 moves in the reverse direction under the urging of the restoring force of the elastic member 500, is pushed back to the plane of the fitting position, and is pressed into the lock body switch lock gear again, so that the return is realized. In this process, even if there is a tolerance (for example, an optional error angle caused by a slight rotation of the motor during the movement), the clutch member 400 can achieve the correct returning of the transmission gear and the lock gear of the lock body switch under the restoring force of the elastic member.

According to an example embodiment of the present application, the process of clutching the lock body 2000 through the second side (e.g., the inner door handle) is as follows: the rotation of the inner door handle drives the second transmission piece 142 on the wedge transmission member 100 to move upwards along the guide piece 130 through the transmission mechanism; the wedge-shaped transmission component 100 pushes the adapter component 300 (such as a block-up piece) in the process of moving upwards; the transferring member 300 pushes the clutch member 400 (e.g., a lock body driving gear) to move along the guide bar 200, thereby leaving a plane where it is engaged and disengaging from a lock body switch lock gear (not shown in the drawings); after the key is separated, the lock gear of the lock body is driven to rotate by the key, so that unlocking is realized. During the process that the adaptor member 300 pushes the clutch member 400 to move, the clutch member 400 compresses the elastic member 500.

After unlocking is finished, the handle in the door rebounds, and the wedge-shaped transmission component 100 is driven to move downwards in the rebounding process; the clutch member 400 is pushed by the restoring force of the elastic member 500 to move in the opposite direction, pushed back to the plane of the fitting position, and pressed into the lock body switch lock gear again, thereby realizing the homing. In this process, even if there is a tolerance (for example, an optional error angle caused by a slight rotation of the motor during the movement), the clutch member 400 can achieve the correct returning of the transmission gear and the lock gear of the lock body switch under the restoring force of the elastic member.

According to another aspect of the application, an automatic lock is also provided, and the automatic lock comprises the lock body.

Compared with the traditional gear transmission clutch structure, the wedge-shaped transmission component for the lock body, the clutch structure, the lock body and the automatic lock are simpler in structure and more convenient to install; the safety dead point does not exist, and the key and the door inner handle can be opened quickly when the door is stopped in any state, so that the safety is improved, and the use experience of a user is improved; the key door opening and the door inner handle door opening can be realized simultaneously through the group of clutch mechanisms, the structure is more compact, and the cost is further reduced; the speed reducer adopts a gear box structure, the inside is sealed and lubricated, the service life is more ensured, and the precision control quantity is good; the clutch part adopts a gear wheel structure for transmission, so that the requirement on the precision of lubrication and transmission matching is lower, and the service life is longer.

The foregoing detailed description of the embodiments of the present application has been presented to illustrate the principles and implementations of the present application, and the description of the embodiments is only intended to facilitate the understanding of the methods and their core concepts of the present application. Meanwhile, a person skilled in the art should, according to the idea of the present application, change or modify the embodiments and applications of the present application based on the scope of the present application.
