[0002] In mechanical transmission systems, the clutch mechanism plays a crucial role. It is responsible for connecting or disconnecting the power transmission between the power source and the actuator, to realize the functions such as starting or stopping of the equipment. Traditional clutch mechanisms have various designs, but they generally have complex structures, slow response speed, insufficient reliability, and high maintenance costs. Especially in application scenarios that require frequent starting and stopping, the durability and flexibility of the clutch mechanism become key factors that restrict the performance of the equipment.

[0003] The clutch mechanisms in the prior art often rely on complex friction pairs or gear meshing to achieve the clutch function. These mechanisms are prone to performance degradation and even failure due to friction wear or gear clearance changes after long-term operation. In addition, some clutch mechanisms also require additional driving devices to control their clutch state, which not only increases the complexity and cost of the system, but also limits the application of the equipment in compact spaces.

[0004] In the existing clutch mechanism, after the clutch mechanism is separated or after troubleshooting, the power source will not be able to continuously provide power to the actuator.

[0047] Please refer to Figures 1 to 8 The present embodiment provides a kind of clutch mechanism, comprising:

[0048] First clutch piece 10, a plurality of open mouth 11 is arranged on the first clutch piece 10, and a plurality of the open mouth 11 is arranged in the form of annular array around the rotation center of the first clutch piece 10;

[0049] Second clutch piece 20, the second clutch piece 20 is arranged on the side of the first clutch piece 10 with the open mouth 11, the side of the second clutch piece 20 towards the first clutch piece 10 is provided with clutch hole 21, and the rotation center of the second clutch piece 20 coincides with the rotation center of the first clutch piece 10;

[0050] Jacks 30, the jacks 30 are movably arranged in the clutch hole 21, one end of the jacks 30 close to the first clutch piece 10 is matched with the open mouth 11, and the end of the jacks 30 is arranged in the open mouth 11;

[0051] Elastic member 40, the elastic member 40 is arranged at the end of the jacks 30 away from the first clutch piece 10, and the elastic member 40 is arranged in the clutch hole 21;

[0052] When the second clutch 20 is stationary due to resistance, the top column 30 is separated from the opening 11, and the first clutch 10 and the second clutch 20 are in a separated state.

[0053] The first clutch 10 rotates around its rotation center, and the first clutch 10 is a column or a disc, preferably a cylinder, and the center line of the cylinder is the rotation center of the first clutch 10. The opening 11 is arranged on the end surface of the column, and the opening 11 is a plurality of openings arranged in a ring around the rotation center of the first clutch 10. The opening 11 is a groove arranged on the end surface of the first clutch 10, and the opening 11 is used to press and / or abut the top column 30 mentioned below.

[0054] The second clutch 20 rotates around its rotation center, and the rotation center of the first clutch 10 coincides with the rotation center of the second clutch 20, and the second clutch 20 is arranged on the side of the first clutch 10 with the opening 11. One side of the second clutch 20 is in continuous contact with the first clutch 10, that is, in the combined state or in the separated state, the first clutch 10 is in continuous contact with the second clutch 20. The side of the second clutch 20 facing the first clutch 10 (that is, the side of the second clutch 20 in contact with the first clutch 10) is provided with the clutch hole 21, which is a blind hole arranged on the second clutch 20. The clutch hole 21 is arranged corresponding to the opening 11, that is, the clutch hole 21 is arranged below the rotation track of the opening 11.

[0055] Further, in this embodiment, the first clutch 10 rotates, the second clutch 20 is fixed, and the second clutch 20 is fixedly connected with the actuator.

[0056] In some embodiments, referring to Figure 9 , the opening 11 can be arranged on the side wall of the column-shaped first clutch 10, the second clutch 20 covers the first clutch 10, and the clutch hole 21 is arranged horizontally.

[0057] The top column 30 is movably arranged in the clutch hole 21 of the second clutch 20, and the end of the top column 30 close to the first clutch 10 is adapted to the opening 11. When the end of the top column 30 is placed in the opening 11, the first clutch 10 and the second clutch 20 are in a connected state, achieving power transmission. When the top column 30 is lowered into the clutch hole 21, the end of the top column 30 is out of the opening 11, and the first clutch 10 and the second clutch 20 are in a separated state. The width and diameter of the top column 30 are adjusted according to the size of the opening 11 to ensure good fitting effect.

[0058] The clutch hole 21 is adapted to the top column 30, and the top column 30 moves in the clutch hole 21 in the vertical direction. The rotation center of the second clutch 20 coincides with the rotation center of the first clutch 10, ensuring that the two are synchronized during rotation.

[0059] The elastic member 40 is arranged at the end of the top column 30 away from the first clutch 10, and the elastic member 40 is located in the clutch hole 21. When there is no external force, the elastic member 40 pushes the top column 30 towards the opening 11, maintaining the connected state of the clutch mechanism.

[0060] When the second clutch 20 is stationary due to resistance, the first clutch 10 presses the top column 30 and makes the top column 30 move downward, and the top column 30 is out of the opening 11, achieving the separation of the clutch mechanism. Due to the continuous rotation of the first clutch 10, when it rotates to the next opening 11, the top column 30 moves towards the opening 11 under the action of the elastic member 40, so that the top column 30 is placed in the opening 11, and then the first clutch 10 and the second clutch 20 are connected again.

[0061] Further, after being connected again, if the resistance on the second clutch 20 disappears, the first clutch 10 will drive the actuator to work through the second clutch 20. If the resistance has not disappeared, the top column 30 will be lowered again until the resistance completely disappears.

[0062] In actual operation, the first clutch 10 and the second clutch 20 are kept in a connected state through the cooperation of the top column 30 and the opening 11, and power is transmitted from the first clutch 10 to the second clutch 20, and then drives the actuator. At this time, the elastic member 40 is in a compressed state, tightly pressing the top column 30 in the opening 11.

[0063] When the second clutch 20 is static due to resistance (such as excessive load or equipment failure), the top column 30 is pressed by the first clutch 10, causing the top column 30 to retract into the clutch hole 21; at this time, the first clutch 10 and the second clutch 20 are in a separated state, and the power source 50 can no longer transmit power to the actuator through the clutch mechanism, thereby protecting the equipment from damage. Then, the first clutch 10 continues to rotate, and the top column 30 moves into the next opening 11; at this time, if the resistance still exists, the top column 30 will repeat the above steps.

[0064] When troubleshooting or resistance disappears, the top column 30 enters the next opening 11, and the connection state of the clutch mechanism is restored to achieve power transmission.

[0065] Unlike the prior art, in the above technical solution, the plurality of openings 11 are arranged in a ring array, and the top column 30 is arranged. The top column 30 can enter the plurality of openings 11 in sequence. When the top column 30 moves out of the opening 11, the first clutch 10 and the second clutch 20 are in a separated state. When the top column 30 moves into the opening 11, the first clutch 10 and the second clutch 20 are in a combined state. This allows the clutch mechanism to constantly switch between the engaged and disengaged states when it is static due to resistance. The elastic member 40 is provided to reset the top column 30, so that the top column 30 has a tendency to move towards the opening 11.

[0066] According to some embodiments of the present application, with reference to Figure 4 , Figure 6 and Figure 7 , the clutch hole 21 is a plurality of, and the plurality of clutch holes 21 are arranged around the center of the rotation axis of the second clutch 20;

[0067] The top column 30 is a plurality of, and the plurality of top columns 30 correspond one-to-one to the plurality of clutch holes 21.

[0068] The clutch hole 21 is a plurality of, and the top column 30 is also a plurality of. Each top column 30 is placed in a clutch hole 21. The plurality of top columns 30 provides sufficient thrust when the first clutch 10 and the second clutch 20 are connected, preventing the top column 30 from falling out of the opening 11 during normal driving.

[0069] According to some embodiments of the present application, with reference to Figures 2 to 3 , the plurality of openings 11 are connected to each other.

[0070] The plurality of the openings 11 are mutually communicated, and the mutually communicated openings 11 are not only used for accommodating the top column 30, but also enable the top column 30 to move along a preset track, thereby avoiding the top column 30 from being separated from the opening 11. Specifically, the plurality of the openings 11 can be directly communicated with each other, that is, there is no gap between the two adjacent openings 11.

[0071] In other embodiments, the openings 11 can also be communicated with each other through the guide groove 12; specifically, the guide groove 12 is arranged between the two adjacent openings 11, and the guide groove 12 is communicated with the two adjacent openings 11, and the guide groove 12 is used for guiding the movement of the top column 30.

[0072] The guide groove 12 is a strip-shaped groove, and the two ends of the guide groove 12 are connected with the two openings 11, respectively. The strip-shaped guide groove 12 is coincided with the annular array track. In use, when the top column 30 is separated from the opening 11, the top column 30 moves along the guide groove 12.

[0073] According to some embodiments of the present application, referring to Figures 1 to 2 and Figure 8 , the power source 50 is further included, the first clutch 10 is drivingly connected with the output end of the power source 50, and the power source 50 is used for driving the first clutch 10 to rotate around the rotation center thereof.

[0074] The power source 50 is an electric motor, and the output end of the power source 50 is fixedly connected with the rotation center of the first clutch 10, so as to output stable power.

[0075] According to some embodiments of the present application, referring to Figure 2 , Figure 4 and Figure 7 , the opening 11 is arc-shaped, and the end of the top column 30 close to the first clutch 10 is arc-shaped.

[0076] Specifically, the cross section of the opening 11 and the cross section of the top column 30 are arc-shaped, so that when the first clutch 10 is pressed downward to touch the top column 30, the opening 11 will not be blocked by the top column 30; that is, the arc-shaped arrangement reduces the resistance when the first clutch 10 and the second clutch 20 are separated. When being pressed, the top column 30 can be separated from the opening 11 along the arc.

[0077] Please refer to Figures 1 to 8 , the embodiment provides a door body 60 for preventing clamping, which comprises a door body 60, a connecting rod 70, and a clutch mechanism according to any one of the embodiments.

[0078] One end of the connecting rod 70 is fixedly connected with the second clutch 20, and the other end of the connecting rod 70 is rotatably connected with the door body 60.

[0079] The door body 60 comprises a first door and a second door, which are arranged as a pair of opposite doors. The first door is provided with a connecting rod 70 and a clutch mechanism, and the second door is correspondingly provided with another connecting rod 70 and another clutch mechanism.

[0080] When the first door and the second door are closing or opening, the first door and / or the second door receives resistance, at which time the first clutch 10 is separated from the second clutch 20, avoiding pinching hands; however, since the power source 50 continuously provides power, the top column 30 reciprocates in the clutch hole 21, that is, the first clutch 10 and the second clutch 20 repeatedly engage, until the resistance disappears, the top column 30 is repositioned in the opening 11, and the power source 50 will drive the second clutch 20 through the first clutch 10 to drive the first door and / or the second door to close or open.

[0081] According to some embodiments of the present application, with reference to Figure 5 , the second clutch 20 is provided with a fixing groove 22 on the side away from the first clutch 10, and the fixing groove 22 is adapted to one end of the connecting rod 70.

[0082] The fixing groove 22 is adapted to one end of the connecting rod 70, that is, the connecting rod 70 is placed in the fixing groove 22 and fixed in the fixing groove 22 by a screw.
