Description

Technical Field

[0001] The present invention relates to the technical field of clutch devices, and in particular to a clutch mechanism and an anti-pinch door body. Background Art

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

[0003] The clutch mechanism in the prior art often relies on complex friction pairs or gear meshing to achieve the clutch function. After working for a long time, these mechanisms are prone to degradation of clutch performance or even failure due to friction wear or changes in gear clearance. In addition, some clutch mechanisms also require additional drive devices to control their clutch state, which not only increases the complexity and cost of the system, but also limits the application of the device in a compact space.

[0004] In the existing clutch mechanism, after the clutch mechanism is separated or the fault is eliminated, the power source will not be able to continue to provide power to the actuator; specifically, after separation, the clutch mechanism needs to be manually switched so that the power source is connected to the actuator structure, and then the power source can provide power to the actuator again. Summary of the invention

[0005] In view of the above problems, the present application provides a clutch mechanism, so that after the fault is eliminated, the clutch mechanism can be quickly switched to a coupled state to improve operating efficiency.

[0006] To achieve the above objectives, the present application provides a clutch mechanism, comprising:

[0007] A first clutch member, wherein the first clutch member is provided with a plurality of openings, and the plurality of openings are arranged in a ring array around a rotation center of the first clutch member;

[0008] a second clutch member, the second clutch member being disposed on a side of the first clutch member having the opening, a clutch hole being provided on a side of the second clutch member facing the first clutch member, and a rotation center of the second clutch member coinciding with a rotation center of the first clutch member;

[0009] A top column, wherein the top column is movably disposed in the clutch hole, one end of the top column close to the first clutch member is adapted to the opening, and an end of the top column is placed in the opening;

[0010] An elastic member, the elastic member is disposed at one end of the top column away from the first clutch member, and the elastic member is disposed in the clutch hole;

[0011] Wherein, when the second clutch member is stationary and rotates due to resistance, the top column is separated from the opening, and the first clutch member and the second clutch member are in a separated state.

[0012] In the technical solution of the embodiment of the present application, there are multiple clutch holes, and the multiple clutch holes are arranged in an array around the center of the rotating shaft of the second clutch member;

[0013] There are multiple top pillars, and the multiple top pillars correspond to the multiple clutch holes one by one.

[0014] In the technical solution of the embodiment of the present application, the plurality of openings are interconnected.

[0015] The technical solution of the embodiment of the present application also includes: a guide groove, which is placed between two adjacent openings and is connected to the two adjacent openings, and the guide groove is used to guide the movement of the top column.

[0016] The technical solution of the embodiment of the present application further includes: a power source, the first clutch component is transmission-connected to the output end of the power source, and the power source is used to drive the first clutch component to rotate around its rotation center.

[0017] In the technical solution of the embodiment of the present application, the opening is arc-shaped, and one end of the top column close to the first clutch member is arc-shaped.

[0018] In the technical solution of the embodiment of the present application, the output end of the power source is fixedly connected to the rotation center of the first clutch member.

[0019] In the technical solution of the embodiment of the present application, the first clutch member is cylindrical, and the second clutch member is cylindrical.

[0020] The present application also provides an anti-pinch door body, comprising: a door body, a connecting rod, and any one of the clutch mechanisms described in the specification;

[0021] One end of the connecting rod is fixedly connected to the second clutch member, and the other end of the connecting rod is rotatably connected to the door body.

[0022] In the technical solution of the embodiment of the present application, a fixing groove is provided on a side of the second clutch member away from the first clutch member, and the fixing groove is adapted to one end of the connecting rod.

[0023] Different from the prior art, in the above technical solution, the plurality of the open annular arrays and the top pillar are arranged, and the top pillar can sequentially enter the plurality of the open openings. When the top pillar moves out of the open opening, the first clutch member and the second clutch member are in a separated state, and when the top pillar moves into the open opening, the first clutch member and the second clutch member are in a combined state. This allows the clutch mechanism to continuously switch clutch states when it is stationary due to resistance. By arranging the elastic member, the top pillar is reset, so that the top pillar has a tendency to move toward the open opening.

[0047] See also Figures 1 to 8 , this embodiment provides a clutch mechanism, including:

[0048] A first clutch member 10, wherein a plurality of openings 11 are disposed on the first clutch member 10, and the plurality of openings 11 are arranged in a ring array around a rotation center of the first clutch member 10;

[0049] A second clutch member 20, the second clutch member 20 is disposed on a side of the first clutch member 10 having the opening 11, a clutch hole 21 is provided on a side of the second clutch member 20 facing the first clutch member 10, and a rotation center of the second clutch member 20 coincides with a rotation center of the first clutch member 10;

[0050] A top column 30, wherein the top column 30 is movably disposed in the clutch hole 21, and one end of the top column 30 close to the first clutch member 10 is adapted to the opening 11, and an end of the top column 30 is placed in the opening 11;

[0051] an elastic member 40, wherein the elastic member 40 is disposed at one end of the top column 30 away from the first clutch member 10, and the elastic member 40 is disposed in the clutch hole 21;

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

[0053] The first clutch 10 rotates around its rotation center. The first clutch 10 is cylindrical or disc-shaped. Preferably, the first clutch 10 is a cylinder, and the center line of the cylinder is the rotation center of the first clutch 10. The opening 11 is disposed on one end surface of the cylinder, and there are multiple openings 11, and the multiple openings 11 are arranged in a circular array around the rotation center of the first clutch 10; the opening 11 is a groove disposed 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 of the second clutch 20. The second clutch 20 is placed on the side of the first clutch 10 having 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 the separated state, the first clutch 10 and the second clutch 20 are in continuous contact. The clutch hole 21 is provided on one side of the second clutch 20 facing the first clutch 10 (that is, the surface on which the second clutch 20 contacts the first clutch 10). The clutch hole 21 is a blind hole placed on the second clutch 20. The clutch hole 21 is arranged corresponding to the opening 11, that is, the clutch hole 21 is placed below the rotation track of the opening 11.

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

[0056] In some embodiments, see Fig. 9 The opening 11 can be placed on the side wall of the first columnar clutch member 10, the second clutch member 20 covers the first clutch member 10, and the clutch hole 21 is arranged horizontally.

[0057] The top column 30 is movably disposed in the clutch hole 21 of the second clutch member 20, and one end of the top column 30 close to the first clutch member 10 is adapted to the opening 11. When the end of the top column 30 is placed in the opening 11, the first clutch member 10 and the second clutch member 20 are in a connected state to achieve power transmission. When the top column 30 moves down to the clutch hole 21, the end of the top column 30 is disengaged from the opening 11, and the first clutch member 10 and the second clutch member 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 a good matching effect.

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

[0059] The elastic member 40 is disposed at one end of the top column 30 away from the first clutch member 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 toward the opening 11 to maintain the connection state of the clutch mechanism.

[0060] When the second clutch 20 is subjected to resistance and is stationary, the first clutch 10 presses the top column 30 and causes the top column 30 to move downward, and the top column 30 is disengaged from the opening 11, thereby realizing the separation of the clutch mechanism. Since the first clutch 10 continues to rotate, when it rotates to the next opening 11, the top column 30 moves toward the opening 11 under the action of the elastic member 40, so that the top column 30 is placed in the opening 11, thereby allowing the first clutch 10 to be connected to the second clutch 20 again.

[0061] Further, after reconnection, if the resistance of the second clutch 20 disappears, the first clutch 10 will drive the actuator to operate through the second clutch 20. If the resistance has not disappeared, the top column 30 is moved down again until the resistance disappears completely.

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

[0063] When the second clutch 20 encounters resistance and stops rotating (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 be transmitted 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 resistance still exists, the top column 30 will repeat the above steps.

[0064] When the fault is eliminated or the 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] Different from the prior art, in the above technical solution, the plurality of openings 11 are arranged in an annular array and the top column 30 is arranged, and the top column 30 can sequentially enter the plurality of openings 11. 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, and 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 continuously switch the clutch state when it is stationary due to resistance. By setting the elastic member 40, the top column 30 is reset, so that the top column 30 has a tendency to move toward the opening 11.

[0066] According to some embodiments of the present application, referring to Figure 4 , Figure 6 as well as Figure 7 There are multiple clutch holes 21, and the multiple clutch holes 21 are arranged in an array around the center of the rotation axis of the second clutch member 20;

[0067] There are a plurality of the top pillars 30 , and the plurality of the top pillars 30 correspond one-to-one to the plurality of the clutch holes 21 .

[0068] There are multiple clutch holes 21 and multiple top pillars 30, and each top pillar 30 is placed in one clutch hole 21. The arrangement of multiple top pillars 30 provides sufficient thrust when the first clutch member 10 and the second clutch member 20 are connected, so as to prevent the top pillar 30 from falling out of the opening 11 during normal driving.

[0069] According to some embodiments of the present application, referring to Figures 2 to 3 , the plurality of openings 11 are interconnected.

[0070] The plurality of openings 11 are interconnected, and the interconnected openings 11 are not only used to accommodate the top column 30, but also enable the top column 30 to move along a preset track to prevent the top column 30 from being separated from the openings 11. Specifically, the plurality of openings 11 can be directly interconnected, that is, there is no gap between two adjacent openings 11.

[0071] In other embodiments, the openings 11 may also be connected to each other through the guide groove 12; specifically, the guide groove 12 is placed between two adjacent openings 11, and the guide groove 12 is connected to the two adjacent openings 11, and the guide groove 12 is used to guide the movement of the top column 30.

[0072] The guide groove 12 is a strip groove, and the two ends of the guide groove 12 are respectively connected to the two openings 11, and the strip guide groove 12 coincides 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 Figure 1 to Figure 2 as well as Figure 8 , further comprising: a power source 50, the first clutch member 10 being transmission-connected to an output end of the power source 50, and the power source 50 being used to drive the first clutch member 10 to rotate around its rotation center.

[0074] The power source 50 is a motor, and the output end of the power source 50 is fixedly connected to the rotation center of the first clutch member 10 to output stable power.

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

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

[0077] See also Figures 1 to 8 , this embodiment provides an anti-pinch door body 60, including: a door body 60, a connecting rod 70 and a clutch mechanism described in any one of the embodiments;

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

[0079] The door body 60 includes a first door and a second door, wherein the first door and the second door are arranged as double doors. The first door is equipped with a connecting rod 70 and a clutch mechanism, and similarly, the second door is correspondingly equipped with another connecting rod 70 and another clutch mechanism.

[0080] When the first door and the second door are closed or opened, the first door and / or the second door encounter resistance, and the first clutch 10 will separate from the second clutch 20 to avoid pinching the hands; however, since the power source 50 continues to provide power, the top column 30 reciprocates in the clutch hole 21, that is, the first clutch 10 and the second clutch 20 are repeatedly engaged and disengaged until the resistance disappears, and the top column 30 is placed back in the opening 11, and the power source 50 will drive the second clutch 20 through the first clutch 10 again to drive the first door and / or the second door to close or open.

[0081] According to some embodiments of the present application, referring to Figure 5 A fixing groove 22 is provided on a side of the second clutch member 20 away from the first clutch member 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 screws.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
