One end of the slider 101 is connected to the clutch 20, the clutch 20 is engaged after the slider 101 moves in a direction away from the clutch 20, and the clutch 20 is disengaged after the slider 101 moves in a direction toward the clutch 20. The transmission member 102 is slidably connected to the slider 101. The direction in which the slider 101 is away from the clutch 20 is a first direction X, and the direction in which the slider 101 is close to the clutch 20 is a second direction Y. The controller 104 is connected to the other end of the slider 101 through the cable 1041, and the controller 104 can tighten the cable 1041 to move the cable 1041 to pull the slider 101 away from the clutch 20. The controller 104 can also release the pull wire 1041 to move the slider 101 in a direction approaching the clutch 20 to reset. As shown in fig. 4, a schematic diagram of the controller 104 controlling the clutch 20 to achieve the engaged state is shown in fig. 4. When the manipulation member 103 is stationary, the controller 104 can control the slider 101 to move in a direction away from or toward the clutch 20 through the pull wire 1041 so that the clutch 20 can be engaged or disengaged, thereby facilitating remote control of the clutch 20.

The operating member 103 is rotatable in the third direction Z to engage the clutch 20, i.e., the operating member 103 is rotated from the state shown in fig. 1 to the state shown in fig. 3; when the clutch 20 is engaged, the operating member 103 is rotated in the opposite direction to the third direction Z to disengage the clutch 20, i.e., the operating member 103 is rotated from the state shown in fig. 3 to the state shown in fig. 1.

The clutch control mechanism 10 can control the clutch 20 not only by manually operating the operating member 103, but also by automatically operating the clutch 20 by the controller 104, and the two modes of controlling the clutch 20 can be switched, so that one of the operating modes can be conveniently selected according to actual conditions when the clutch control mechanism is applied, thereby improving the convenience of controlling the clutch 20.

Referring to fig. 1 and 2, in some embodiments, the manipulating member 103 includes a manipulating lever 1031 and a first swing arm 1032. The transmission member 102 includes a second swing arm 1022, one end of the first swing arm 1032 is fixedly connected with the operating lever 1031 and rotatably connected with the frame 200, the other end of the first swing arm 1032 is hinged to the second swing arm 1022, and the second swing arm 1022 can drive the sliding member 101 to move in a direction away from or close to the clutch 20.

When the lever 1031 rotates, the lever 1031 drives the first swing arm 1032 to rotate, and the first swing arm 1032 can transmit power to the second swing arm 1022, so that the second swing arm 1022 drives the slider 101 to move in a direction away from or close to the clutch 20. When the second swing arm 1022 drives the sliding piece 101 to move away from the clutch 20, the clutch 20 is combined; when the second swing arm 1022 drives the slider 101 to move in a direction approaching the clutch 20, the clutch 20 is disengaged. That is, when the lever 1031 rotates in the third direction Z, the second swing arm 1022 drives the slider 101 to move in the first direction X, and the clutch 20 is engaged, as shown in fig. 3; when the lever 1031 rotates in the opposite direction of the third direction Z, the second swing arm 1022 drives the slider 101 to move in the second direction Y, and the clutch 20 is disengaged, as shown in fig. 1 and 2.

Referring to fig. 2, in some embodiments, the second swing arm 1022 has a receiving cavity 1023 and a sliding hole 1024, and the sliding member 101 can slide in a direction sliding into or out of the receiving cavity 1023 through the sliding hole 1024. The sliding member 101 slides in a direction away from the clutch 20, i.e., in the first direction X when the sliding member 101 slides into the accommodation chamber 1023, and slides in a direction closer to the clutch 20, i.e., in the second direction Y when the sliding member 101 slides out of the accommodation chamber 1023.

Referring to fig. 4 and 5, fig. 4 and 5 show a schematic configuration of the clutch 20 when the controller 104 is used to control the clutch. When the controller 104 pulls the pull wire 1041 to tighten, the sliding member 101 moves in the direction of sliding into the accommodating cavity 1023 under the driving of the pull wire 1041, that is, the sliding member 101 moves in the first direction X, so that the clutch 20 can be engaged. When the controller 104 releases the wire 1041, the wire 1041 releases the pulling force on the slider 101, and the slider 101 moves in the direction of sliding out of the accommodating chamber 1023, that is, the slider 101 moves in the second direction Y, so that the clutch 20 is disengaged. In the process of sliding the sliding member 101 relative to the second swing arm 1022, the sliding member 101 slides into the accommodating cavity 1023 or slides out of the accommodating cavity 1023 through the sliding hole 1024, and the sliding hole 1024 and the accommodating cavity 1023 can limit the sliding path of the sliding member 101, so as to improve the working stability of the clutch control mechanism 10.

Referring to fig. 1 and 2, in some embodiments, the sliding member 101 includes a sliding rod 1011 and a first limiting member 1012, the first limiting member 1012 is disposed on the sliding rod 1011, the sliding rod 1011 is slidably connected with the transmission member 102, and the first limiting member 1012 is disposed on the sliding rod 1011 and cooperates with the transmission member 102 to prevent the sliding rod 1011 from being separated from the transmission member 102. When the transmission member 102 moves away from the clutch 20, the first limiting member 1012 can form a limit with the transmission member 102, so that the transmission member 102 drives the sliding rod 1011 to slide in the first direction X.

When the clutch 20 is controlled by the operating lever 1031, after the operating lever 1031 rotates, the transmission member 102 can move in the first direction X, at this time, the first limiting member 1012 can form a limit with the transmission member 102, so that the transmission member 102 and the sliding rod 1011 are limited to slide relatively, so that the transmission member 102 can drive the sliding rod 1011 to move in the first direction X, and the clutch 20 can be conveniently combined by manually controlling the operating lever 1031.

Referring to fig. 1 and 2, in some embodiments, the sliding rod 1011 is slidably disposed in the sliding hole 1024 and can slide into the accommodating chamber 1023 or slide out of the accommodating chamber 1023 through the sliding hole 1024. Here, "slide-in accommodating chamber 1023" means that a part of the sliding lever 1011 slides into the accommodating chamber 1023 from the sliding hole 1024, another part is located outside the accommodating chamber 1023, and "slide-out accommodating chamber 1023" means that a part of the sliding lever 1011 slides out of the accommodating chamber 1023 from the sliding hole 1024, another part is located in the accommodating chamber 1023.

The first limiting member 1012 is located in the accommodating cavity 1023. When the transmission member 102 moves in the first direction X, the first limiting member 1012 can abut against the inner cavity wall of the accommodating cavity 1023, and the second swing arm 1022 applies a force to the first limiting member 1012 in the first direction X through the inner cavity wall of the accommodating cavity 1023, so that the second swing arm 1022 moves in the first direction X to drive the sliding rod 1011 to move in the first direction X, thereby realizing the combination of the clutch 20.

Referring to fig. 1 and 2, in some embodiments, the first limiting member 1012 includes a first nut 1013, where the first nut 1013 is sleeved on the sliding rod 1011 and is screwed with the sliding rod 1011. The first nut 1013 is detachably coupled to the sliding lever 1011 to facilitate the disassembly and assembly of the sliding member 101.

Referring to fig. 2, 4 and 5, in some embodiments, the sliding member 101 further includes a second limiting member 1014, the second limiting member 1014 is disposed on the sliding rod 1011, the first limiting member 1012 is spaced from the second limiting member 1014, and a distance between the first limiting member 1012 and the second limiting member 1014 is a sliding distance of the sliding rod 1011 relative to the driving member 102. When the controller 104 tightens the cable 1041 to the clutch 20, the second stop 1014 can form a stop with the transmission 102 to limit the relative sliding movement of the transmission 102 and the sliding bar 1011.

When the slide lever 1011 is controlled by the pull wire 1041 of the controller 104, the slide lever 1011 can slide with respect to the transmission member 102, and the sliding range of the slide lever 1011 is between the first stopper 1012 and the second stopper 1014. When the controller 104 tightens the pull wire 1041 to engage the clutch 20, the second stop 1014 forms a stop with the transmission assembly to limit the sliding movement from continuing to slide away from the clutch 20, so that the sliding member 102 is not prone to over-engaging the clutch 20 due to excessive distance from the clutch 20 during sliding. When the controller 104 releases the cable 1041, the sliding rod 1011 slides in a direction approaching the clutch 20 until the first limiting member 1012 and the transmission member 102 form a limit. The first and second stoppers 1012 and 1014 can limit the sliding range of the sliding rod 1011, thereby making the clutch 20 less vulnerable to damage.

Referring to fig. 4 and 5, in some embodiments, the second stopper 1014 is located outside the receiving cavity 1023. When the transmission member 102 moves in the second direction Y, the second stopper 1014 can abut against the outer wall surface of the second swing arm 1022, so that when the second swing arm 1022 moves in the second direction Y, the second swing arm 1022 releases the force applied to the first stopper 1012 in the first direction X, and the first stopper 1012 and the slide lever 1011 can move in the second direction Y until the outer wall surface of the second swing arm 1022 is restricted by the second stopper 1014.

Referring to fig. 4 and 5, in some embodiments, the second limiting member 1014 is a second nut 1015, and the second nut 1015 is sleeved on the sliding rod 1011 and is screwed with the sliding rod 1011. The second nut 1015 is detachably coupled to the sliding rod 1011 to facilitate the disassembly and assembly of the sliding member 101.

Referring to fig. 4 and 5, in some embodiments, the sliding member 101 further includes a sliding sleeve 1016, where the sliding sleeve 1016 is sleeved on the sliding rod 1011 and is located between the first limiting member 1012 and the second limiting member 1014. The sliding sleeve 1016 slides relative to the transmission member 102 as the controller 104 tightens or releases the cable 1041. When the lever 1031 is rotated, the transmission member 102 slides relative to the slide 1016.

When the clutch 20 is controlled by the controller 104, the slide 1016 and the slide rod 1011 slide integrally with respect to the transmission 102 under the traction of the cable 1041. When the lever 1031 controls the clutch 20, the lever 1031 drives the transmission member 102 to slide, so that the transmission member 102 slides integrally with the sliding lever 1011 relative to the sliding sleeve 1016. The sliding sleeve 1016 is sleeved on the sliding rod 1011, so that the sliding rod 1011 is not easy to be in direct contact with the transmission part 102, friction of the transmission part 102 on the sliding rod 1011 is reduced, the sliding rod 1011 is not easy to wear, and the service life of the sliding rod 1011 is prolonged. In addition, the sliding sleeve 1016 can limit the movement of the first limiting member 1012 and the second limiting member 1014, so that the mounting stability of the first limiting member 1012 and the second limiting member 1014 can be improved.

Referring to fig. 2, 4 and 5, in some embodiments, the first stop 1012 further includes a first spacer 1017 and the second stop 1014 includes a second spacer 1018. The first spacer 1017 is disposed between the first nut 1013 and one of the end surfaces of the sliding sleeve 1016, and the second spacer 1018 is disposed between the second nut 1015 and the other end surface of the sliding sleeve 1016. The first gasket 1017 can increase the contact area between the first nut 1013 and the sliding sleeve 1016, so that the first nut 1013 is not easy to loosen; the second spacer 1018 can increase the contact area between the second nut 1015 and the sliding sleeve 1016, so that the second nut 1015 is not easy to loosen. The provision of the first spacer 1017 and the second spacer 1018 improves the stability of the assembly of the slider 101.

In some embodiments, at least one of the first stop 1012 and the second stop 1014 is movably disposed on the sliding bar 1011. For example, the first limiting member 1012 and the second limiting member 1014 are both nuts and are screwed with the screw. The arrangement is convenient for adjusting the position of the sliding sleeve 1016 on the sliding rod 1011 by adjusting the position of the first limiting piece 1012 or the second limiting piece 1014 on the sliding rod 1011, and the position of the first limiting piece 1012 or the second limiting piece 1014 can be adaptively adjusted according to the length of the sliding sleeve 1016, so that the separation and combination states of the clutch 20 can be conveniently adjusted according to actual needs.

Referring to fig. 1 and 2, in some embodiments, the clutch control mechanism 10 further includes an elastic member 105, where one end of the elastic member 105 is connected to the sliding member 101, and the other end is used to connect to the clutch 20. The slider 101 can transmit a pulling force to the clutch 20 through the elastic member 105 so as to control the engagement of the clutch 20. In addition, the elastic member 105 can absorb vibration and impact force, so that the clutch 20 is not easily damaged, and the working stability of the clutch 20 is improved.

Referring to fig. 1 and 2, in some embodiments, one end of the elastic member 105 is connected to the sliding rod 1011, and the other end is connected to the tensioning wheel 2041. When the sliding rod 1011 moves in the first direction X, the elastic member 105 pulls the tensioning wheel 2041 in the first direction X, the tensioning wheel 2041 approaches the driving belt 203, so that the driving belt 203 is tensioned, and the driving wheel 201 transmits power to the driven wheel 202 through the driving belt 203, so as to complete the engagement of the clutch 20. When the clutch 20 is disengaged, the contraction force of the elastic member 105 can drive the sliding rod 1011 to move in the second direction Y, the tensioning mechanism 204 releases the tensioning action on the driving belt 203, the driving belt 203 is relaxed, and the power of the driving wheel 201 cannot be transmitted to the driven wheel 202, so that the clutch 20 is disengaged.

In some embodiments, the controller 104 is communicatively or electrically connected to the digital information manipulation device, and one end of the pull wire 1041 is connected to the sliding rod 1011, and the other end is connected to the controller 104. The digital information control device controls the operation of the controller 104 through the digital information, and the controller 104 controls the tightening and releasing of the pull wire 1041 to realize the combination and the separation of the clutch 20.

When the clutch 20 is engaged by the digital information, the controller 104 receives the engagement information and tightens the cable 1041. The pull wire 1041 drives the sliding rod 1011 to move along the first direction X, as shown in fig. 4 and 5. The sliding rod 1011 drives the elastic element 105 and the tensioning mechanism 204 to move, and the tensioning mechanism 204 compresses the driving belt 203 to be in a tensioning state, so that the power of the driving wheel 201 is transmitted to the driven wheel 202, and the clutch 20 is combined.

When the clutch 20 is controlled to be disengaged by the digital information, the controller 104 releases the pull wire 1041 after receiving the disengagement information. The lever connected to the wire 1041 slides in the second direction Y by receiving the restoring force of the elastic member 105 and the tension mechanism 204, and the elastic member 105 and the tension mechanism 204 are not biased in the first direction X. The tensioning mechanism 204 releases the driving belt 203 under the action of the elastic restoring member 2043 to be in a loose state, so that the power of the driving wheel 201 cannot be transmitted to the driven wheel 202, and the clutch 20 is separated.

In this scheme, not only can control the clutch 20 through manual manipulation piece 103, but also can control the clutch 20 through the automation of the controller 104, two kinds of modes of controlling the clutch 20 can be switched, and one of them operation mode is convenient to select according to actual conditions when using to improve the convenience to the clutch 20 control.

In addition, other variations within the scope of the present application will be apparent to those skilled in the art, and such variations are intended to be included within the scope of the present disclosure.
