Embodiment 1）

[0032] See figure 1 , figure 2 , image 3 , Figure 4 , the present invention provides a clutch quick release mechanism, including a screw, a worm gear 1, a clutch 2 that is in transmission cooperation with the worm gear 1, and a controller 3 acting on the worm gear 1, the screw includes a screw head 4 and a screw main body 5, The worm gear 1 is sleeved on the screw head 4 and can be displaced axially along the screw head 4 , the clutch 2 is sleeved on the screw main body 5 , and the controller 3 is used to drive the worm gear 1 to disconnect from the clutch 2 .

[0033] This embodiment is a basic embodiment of a clutch quick release mechanism. The axis line of the screw head 4 is the same as the axis line of the screw body 5, but there is a gap between the screw head 4 and the screw body 5. not in contact. The clutch 2 can be connected to the main body of the screw rod 5 in an interference fit manner. The screw head 4 can be made of a material with a low coefficient of ...

Embodiment 2）

[0037] See figure 1 , figure 2 , image 3 , Figure 4 The difference between this embodiment and Embodiment 1 is that the controller 3 has a control switch 31, a connecting portion 32, a first elastic member 33, and a toggle switch 34, and the control switch 31 and the toggle switch 34 are located at the connecting portion 32 respectively. At both ends, the first elastic member 33 is located between the connecting portion 32 and the toggle switch 34 . When the control switch 31 rotates, it drives the connecting portion 32 to rotate, and the connecting portion 32 drives the toggle switch 34 to rotate, and the toggle switch 34 toggles the worm gear 1 away from the clutch 2 for release. The first elastic member 33 may be, but not limited to, elastic members such as torsion springs, and the first elastic member 33 provides a restoring force to return to the original position after the toggle switch 34 is toggled.

Embodiment 3）

[0039] See figure 2 , image 3The difference between this embodiment and Embodiment 1 is that the screw head 4 is fixedly connected with a support 6 , and a second elastic member 8 is provided between the worm wheel 1 and the support 6 . The support 6 may be, but not limited to, a ball bearing. During normal operation, the second elastic member 8 provides an axial force to press the worm gear 1. The second elastic member 8 can be but not limited to compression springs, wave springs and other elastic components. After the controller 3 realizes the effective release, the second elastic member 8 can make the worm gear 1 return to its original position, continue to cooperate with the clutch 2 to work or wait for the next release.

[0040] The screw head 4 and the support member 6 can also be an integral structure, and the screw head 4 and the support member 6 are used for interference fit. Alternatively, as a structural improvement and optimization, a first sleeve 7 may be pro...

Abstract

The invention relates to the technical field of linear actuators, provides a linear actuator, and relates to a clutch quick release mechanism. The mechanism comprises a lead screw, a worm gear, a clutch in transmission fit with the worm gear and a controller acting on the worm gear, the lead screw comprises a lead screw head and a lead screw body, the worm gear is arranged on the lead screw head in a sleeving mode and can move in the axial direction of the lead screw head, the clutch is arranged on the lead screw body in a sleeving mode, and the controller is used for driving the worm gear to be disconnected from the clutch. In the releasing process, the clutch device mainly depends on the controller to stir the worm gear, so that the worm gear can be disconnected from the clutch, when the worm gear is disconnected from the clutch, the controller can only generate pressure on the shaft end of the lead screw head and cannot generate corresponding adverse friction resistance on the lead screw body, and therefore the lead screw body cannot be affected, and releasing can be smooth.

Description

technical field [0001] The invention relates to the technical field of linear actuators, in particular to a clutch quick release mechanism and a linear actuator. Background technique [0002] Linear actuators, also known as electric actuators, are widely used in smart homes, automobiles, medical care, solar power generation, and more. Due to the diverse application environments of linear actuators, linear actuators may encounter drive motor failures, power failures, or other unexpected power cuts, so the setting of the release function is very necessary, and high-end products have more and more requirements for the release function. higher. The so-called release mainly refers to cutting off the power between the drive motor and the screw, so that the reverse push can be realized by manually driving the screw to rotate. [0003] In the prior art, the setting of the release mechanism has relatively large disadvantages. On the one hand, due to the resistance and friction bet...
