[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0028] In order to facilitate the repair of the motor when the motor fails, the present application provides a clutch structure that can separate the motor from the actuator when the motor fails, thereby facilitating the repair of the motor.

[0029] A clutch structure, see Figures 1 to 4 The clutch structure includes a housing 1, a slider 2, an output shaft 8, an input shaft 3 and a drive assembly. The slider 2 is slidably arranged inside the housing 1, and the output shaft 8 is rotatably arranged inside the housing 1. The output shaft 8 has a first connecting member 31 on the end face of the output shaft 8 facing the output shaft 8, and has a second connecting member 81 on the end face of the output shaft 8 facing the input shaft 3. The first connecting member 31 and the second connecting member 81 are plugged into each other to form a rotating whole or disengage; the drive assembly is arranged on the housing 1, and the drive assembly is connected to the slider 2, and the drive assembly provides power for the slider 2 to slide toward or away from the input shaft 3.

[0030] Among them, the present application sets a clutch structure between the motor and the actuator, so that when the motor fails, the motor and the actuator can be separated by the clutch structure, thereby overcoming the self-locking of the motor that makes it impossible to quickly reset and move the actuator; and after the motor and the actuator are separated by setting the clutch structure, it is also convenient to move and repair the motor.

[0031] Specifically, when the first connecting member 31 and the second connecting member 81 are plugged in, the output shaft 8 and the input shaft 3 are driven to cooperate to form a rotating whole, and the output shaft 8 can rotate synchronously under the drive of the input shaft 3. At this time, the clutch structure is in a working state and can output to the outside; when the first connecting member 31 and the second connecting member 81 are separated, the output shaft 8 and the input shaft 3 are disengaged, and the rotation of the input shaft 3 cannot be transmitted to the output shaft 8. At this time, the clutch structure is in a separated state and cannot output to the outside. The drive assembly is used to drive the slider 2 to move, and the output shaft 8 and the input shaft 3 can be driven to connect or separate, thereby controlling the clutch structure to be in a working state or a separated state. The clutch structure is controlled to switch between the working state and the separated state through the drive assembly, which is convenient for separating the motor from the actuator when the motor fails, and for resetting and moving the actuator and repairing the motor.

[0032] It should be noted that the actuator is not limited in the present application and can be any structure that cooperates with the output shaft 8 in driving.

[0033] In this embodiment, the slider 2 is driven to slide by the driving component. When the input shaft 3 and the output shaft 8 need to be disengaged, the slider 2 can drive the output shaft 8 to move along the side away from the input shaft 3, thereby completing the release of the drive cooperation between the input shaft 3 and the output shaft 8. At this time, the clutch structure is in a disengaged state; when the input shaft 3 and the output shaft 8 need to be driven and cooperated, the slider 2 is driven by the driving component to move toward the input shaft 3, and the slider 2 drives the output shaft 8 to move toward the input shaft 3 and cooperate with the input shaft 3. At this time, the clutch structure switches to the working state, and the motor can cooperate with the actuator drive through the clutch structure.

[0034] Furthermore, the input shaft 3 and the output shaft 8 are coaxial, and a plurality of first connecting members 31 and a plurality of second connecting members 81 are provided in a one-to-one correspondence, and the plurality of first connecting members 31 and the plurality of second connecting members 81 are arranged at intervals along the circumference of the input shaft 3 .

[0035] The input shaft 3 and the output shaft 8 are coaxial, so that the input shaft 3 can better drive the output shaft 8 to rotate, which is beneficial to improving the stability of the connection between the input shaft 3 and the output shaft 8 .

[0036] Among them, the plurality of first connecting members 31 and second connecting members 81 arranged in one-to-one correspondence can increase the stability of the input shaft 3 and the output shaft 8 after they are matched, and further enable the output shaft 8 to drive the actuator more stably.

[0037] Further, one of the first connecting member 31 and the second connecting member 81 is a spring pin, and the other of the first connecting member 31 and the second connecting member 81 is a slot.

[0038] In this embodiment, the first connecting member 31 is a spring pin, and the second connecting member 81 is a slot.

[0039] Specifically, since the spring pin can be compressed, when the spring pin contacts the end of the output shaft 8, if the spring pin is not aligned with the slot, the spring pin will be compressed first, and as the input shaft 3 rotates, the spring pin can rotate to a position aligned with the slot, at which time the compressed spring pin pops out, and the spring pin is inserted into the slot to complete the connection between the input shaft 3 and the output shaft 8. By matching the spring pin and the slot, the input shaft 3 can be matched with the output shaft 8 during the rotation process. Blind plug docking can be performed at any stop angle, which improves the convenience and efficiency of the module.

[0040] Furthermore, an annular groove 82 is provided on the surface of the output shaft 8 facing the input shaft 3 , the notch of the annular groove 82 is arranged toward the input shaft 3 , and the slot is arranged on the bottom surface of the annular groove 82 .

[0041] When the spring latch abuts against the output shaft 8 toward the side of the input shaft 3, the spring latch will first enter the annular groove 82, and then as the input shaft 3 rotates, the spring latch will enter the slot. During this process, the annular groove 82 can limit and guide the spring latch, making it easier for the spring latch to be inserted into the slot.

[0042] Furthermore, the end of the spring pin shaft facing the slot is an arc surface. By setting the end of the spring pin facing the annular groove 82 as an arc surface, the spring pin can slide inside the annular groove 82 conveniently. The arc surface structure is conducive to reducing friction resistance, which can save time and effort when switching the clutch structure.

[0043] Furthermore, the housing 1 has a sliding hole 11 extending axially along the output shaft 8, and the driving assembly includes a bracket 6, a rocker 7, a transmission structure 5 and a connecting member 4. The bracket 6 is arranged on the housing 1 and is located outside the housing 1. The rocker 7 is rotatably arranged on the bracket 6. The rocker 7 is drivingly connected to the input end of the transmission structure 5, and the output end of the transmission structure 5 is connected to the connecting member 4. The connecting member 4 passes through the sliding hole 11 and is connected to the slider 2. The rocker 7 drives the connecting member 4 to slide inside the sliding hole 11 through the transmission structure 5.

[0044] Specifically, after the rocker 7 is toggled, the connecting member 4 will slide in the sliding hole 11 through the transmission of the transmission structure 5, and the connecting member 4 is fixedly connected to the slider 2, so when the connecting member 4 moves under the drive of the rocker 7, the slider 2 will also move synchronously with the connecting member 4; at the same time, the sliding hole 11 limits the sliding of the connecting member 4, so that the connecting member 4 can only slide along the length direction of the sliding hole 11, which is conducive to improving the accuracy and stability of the movement of the slider 2. The present application realizes the movement of the slider 2 by driving the slider 2 to move through the structural coordination of the rocker 7, the transmission structure 5, and the connecting member 4, and then drives the output shaft 8 to move through the slider 2, so as to realize the mutual coordination or separation between the input shaft 3 and the output shaft 8, and facilitates the control.

[0045] Furthermore, the bracket 6 is arranged outside the housing 1 , and the rocker 7 arranged on the bracket 6 is located outside the housing 1 , so that the slider 2 can be driven to move by the rocker 7 .

[0046] See also Figures 1 to 4 The transmission structure 5 includes a first rotating arm 71 and a second rotating arm 72. The rocker 7 is drivingly connected to the first end of the first rotating arm 71. The rocker 7 provides driving force for the rotation of the first rotating arm 71. The second end of the first rotating arm 71 is rotationally connected to one end of the second rotating arm 72. The other end of the second rotating arm 72 is drivingly connected to the connecting member 4.

[0047] A connecting rod mechanism is formed between the rocker 7 , the first rotating arm 71 and the second rotating arm 72 , so the rocker 7 can conveniently and labor-savingly drive the connecting member 4 to slide.

[0048] Furthermore, the clutch structure further includes a first bearing, which is disposed inside the housing 1, and the input shaft 3 is rotatably connected to the housing 1 via the first bearing. The first bearing can reduce the friction force of relative rotation between the input shaft 3 and the housing 1, thereby improving the input efficiency of the clutch structure.

[0049] Furthermore, the clutch structure further includes a second bearing, the slider 2 has a channel structure, the second bearing is arranged inside the channel structure, and the output shaft 8 is slidably arranged on the slider 2 through the second bearing. The second bearing can reduce the friction force of the relative rotation between the output shaft 8 and the slider 2, thereby improving the output efficiency of the clutch structure.

[0050] Furthermore, a spline groove is provided at one end of the output shaft 8 away from the input shaft 3, and the spline groove is used to cooperate with the spline shaft. The spline shaft is the input end of the actuator, and the spline shaft cooperates with the spline groove to facilitate the rapid installation of the actuator and the transmission of large torque.

[0051] In this embodiment, the clutch structure further includes a sliding member 22. The slider 2 is provided with at least one shaft hole 21 extending along the axial direction of the input shaft 3. The sliding member 22 is arranged inside the shaft hole 21. The housing 1 is provided with an extension shaft extending along the axial direction of the input shaft 3. The sliding member 22 is slidably arranged on the extension shaft. The sliding member 22 is a linear bearing or an oil-free bushing. The slider 2 slides on the housing 1 through the cooperation of the sliding member 22 and the shaft hole 21. The arrangement of the sliding member 22 can reduce the friction of the slider 2 and reduce the sliding resistance. At the same time, the axially arranged extension shaft has the function of guiding and limiting, which is conducive to improving the stability of the movement of the slider 2.

[0052] Embodiment 2

[0053] Different from the first embodiment, in this embodiment, the first connecting member 31 is a slot, and the second connecting member 81 is a spring pin.

[0054] Specifically, since the spring pin can be compressed, when the spring pin contacts the end of the input shaft 3, if the spring pin is not aligned with the slot, the spring pin will be compressed first, and as the input shaft 3 rotates, the slot can rotate to a position aligned with the spring pin, at which time the compressed spring pin pops out, and the spring pin is inserted into the slot to complete the connection between the input shaft 3 and the output shaft 8. By matching the spring pin and the slot, the input shaft 3 can be matched with the output shaft 8 during the rotation process. Blind plug docking can be performed at any stop angle, which improves the convenience and use efficiency of the module.

[0055] In this embodiment, an annular groove 82 is provided on the surface of the input shaft 3 facing the output shaft 8 , the notch of the annular groove 82 is arranged toward the output shaft 8 , and the slot is arranged on the bottom surface of the annular groove 82 .

[0056] When the spring latch abuts against the input shaft 3 toward the output shaft 8, the spring latch will first enter the annular groove 82, and then as the input shaft 3 rotates, the spring latch will enter the slot. During this process, the annular groove 82 can limit and guide the spring latch, making it easier for the spring latch to be inserted into the slot.

[0057] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0058] In some automation application scenarios of this application, when an abnormality occurs in a motor, the motor will self-lock, and the motor and the actuator will be separated through the clutch structure, thereby overcoming the inability to quickly reset and move the actuator due to the motor self-locking; and after the motor and the actuator are separated by setting the clutch structure, it is also convenient to move and repair the motor. When an abnormality occurs in the motor, the motor and the actuator can be separated to get rid of the self-locking state of the motor.
