[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 This application provides a guiding mechanism, which includes a guiding member 1, a limiting member 2, a movable member 3, and an elastic member 4. Among them, the limiting member 2 is disposed opposite to the guiding member 1 along the first direction z to jointly enclose a movable channel d with the guiding member 1; along the first direction z, the guiding member 1 and the limiting member 2 can move relative to each other; at least a part of the movable member 3 is movably disposed in the movable channel d; the elastic member 4 is used to drive the limiting member 2 to move in the direction close to the guiding member 1, so that the limiting member 2 applies a force towards the guiding member 1 to the movable member 3, causing the movable member 3 to abut against the guiding member 1.
[0034] In such a structural form, the elastic force of the elastic member 4 acts on the movable member 3 through the limiting member 2, causing the movable member 3 to abut against the guiding member 1. In this way, on the one hand, the movable member 3 is limited between the limiting member 2 and the guiding member 1, enabling the limiting member 2 and the guiding member 1 to realize the guiding function for the movable member 3. On the other hand, the gap between the limiting member 2 and the movable member 3, as well as the gap between the guiding member 1 and the movable member 3, can be compensated, that is, the gap between the inner surface of the guiding channel and the movable member 3 can be compensated, and the cooperation between the movable member 3 and the inner surface of the guiding channel is relatively tight, which is beneficial to improving the stability of the movable member 3 during the movement along the guiding channel, reducing the impact between the movable member 3 and the inner surface of the guiding channel, and thus being beneficial to reducing abnormal noise.
[0035] It can be understood that in the embodiments of the present application, the gap between the limiting member 2 and the movable member 3, and the gap between the guiding member 1 and the movable member 3 can be compensated, so that the requirements for the machining accuracy of the limiting member 2, the movable member 3 and the guiding member 1 are relatively low. Even if the machining accuracy of the limiting member 2, the movable member 3 and the guiding member 1 is slightly poor, it is not easy for the limiting member 2 and the guiding member 1 to generate a gap with the movable member 3, which is beneficial to reducing costs.
[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 , it can be understood that in the embodiments of the present application, at least a part of the movable member 3 is disposed in the movable channel d, that is, along the first direction z, at least a part of the movable member 3 is limited between the limiting member 2 and the guiding member 1.
[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 , it should be explained that in the embodiments of the present application, the movable channel d is used to guide the movement of the movable member 3, and the movable member 3 can move relative to the movable channel d along the extension path of the movable channel d, that is, the movable member 3 can move along the side surfaces of the limiting member 2 and the guiding member 1 that approach each other along the first direction z.
[0038] Please refer to Figure 1 、 Figure 2 and Figure 3 , it can be understood that in the embodiments of the present application, the limiting member 2 exerts a force on the movable member 3 towards the guiding member 1, so that the movable member 3 abuts against the guiding member 1, that is, along the first direction z, the movable member 3 is clamped between the limiting member 2 and the guiding member 1, which enables the side surfaces of the limiting member 2 and the guiding member 1 that approach each other along the first direction z to guide the movement of the movable member 3.
[0039] Please refer to Figure 1 、 Figure 2 and Figure 3 , it can be understood that in the embodiments of the present application, since the elastic member 4 can deform, during the process of the movable member 3 moving relative to the movable channel d, driven by the movable member 3, along the first direction z, the limiting member 2 can move in a direction away from the guiding member 1. Along the first direction z, the amount of movement of the limiting member 2 relative to the guiding member 1 is the same as the amount of deformation of the elastic member 4. The limiting member 2 can move in a direction away from the guiding member 1 driven by the movable member 3, so that during the process of the movable member 3 moving relative to the movable channel d, the inner surface of the movable channel d has less obstruction to the movable member 3, which is beneficial to improving the smoothness of the movable member 3 during the movement relative to the movable channel d.
[0040] It can be understood that in the embodiments of the present application, the smaller the elastic force exerted by the elastic member 4 in the first direction z between the limiting member 2 and the guiding member 1, the smaller the pre-tightening force between the movable member 3 and the inner surface of the movable channel d, and the smoother the movement of the movable member 3 relative to the movable channel d. However, the guiding accuracy of the movable channel d for the movable member 3 is worse. On the contrary, the larger the elastic force exerted by the elastic member 4 in the first direction z between the limiting member 2 and the guiding member 1, the larger the pre-tightening force between the movable member 3 and the inner surface of the movable channel d, and the worse the smoothness of the movement of the movable member 3 relative to the movable channel d. However, the guiding accuracy of the movable channel d for the movable member 3 is higher. Personnel can flexibly adjust the elastic force exerted by the elastic member 4 in the first direction z between the limiting member 2 and the guiding member 1 according to the load on the movable member 3, so as to balance the smoothness of the movement of the movable member 3 relative to the movable channel d and the guiding accuracy.
[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments of the present application, the guiding mechanism further includes a base, and the guiding member 1 is fixedly connected to the base. The fixed connection can be snap connection, bonding, welding, fastener connection or integral molding, etc. In some embodiments of the present application, it can also be that the limiting member 2 is fixedly connected to the base, and the fixed connection can be snap connection, bonding, welding, fastener connection or integral molding, etc.

The guiding post 5 is limited to the guiding member 1 in the first direction z, and the guiding post 5 is in clearance fit with the guiding hole, so that the guiding post 5 and the guiding hole can translate relative to each other in the first direction z, and further the guiding member 1 and the limiting member 2 can translate relative to each other along the first direction zz.
[0044] Please refer to Figure 4 、 Figure 5 and Figure 6, in some embodiments of the present application, the guide post 5 can be fixedly connected to the limiting member 2 so that the guide post 5 is limited to the guide member 1 in the first direction z. In some embodiments of the present application, it can also be that the guide post 5 is snap-fitted to the guide member 1 in the first direction z so that the guide post 5 is limited to the guide member 1 in the first direction z.
[0045] Please refer to Figure 4 , Figure 5 and Figure 6 , it can be understood that in the embodiments of the present application, the axial direction of the guide post 5 is the same as the depth direction of the guide hole, both being the first direction z.
[0046] Please refer to Figure 4 , Figure 5 and Figure 6 , in some embodiments of the present application, the guide post 5 is formed with an abutting portion 51 protruding radially outward. Along the first direction z, the limiting member 2 is located between the abutting portion 51 and the guide member 1. The guide post 5 passes through the guide hole and is connected to the guide member 1. The two ends of the elastic member 4 are respectively supported by the end face of the guide hole and the abutting portion 51. In such a structural form, the guide post 5 is used for guiding the relative movement between the limiting member 2 and the guide member 1 on the one hand, and on the other hand, an abutting portion 51 is formed to support the spring. The guide post 5 is fully utilized, which is beneficial to improving the integration degree of the guiding mechanism and reducing the cost.
[0047] Please refer to Figure 4 , Figure 5 and Figure 6 , it should be explained that in the embodiments of the present application, the guide post 5 passes through the guide hole and is connected to the guide member 1, that is, the guide member 1 is provided with the guide post 5.
[0048] Please refer to Figure 4 , Figure 5 and Figure 6 , it can be understood that in the embodiments of the present application, the guide hole is a through hole.
[0049] Please refer to Figure 4 , Figure 5 and Figure 6 , it should be explained that in this embodiment, the elastic member 4 is in an elastically compressed state, and the elastic direction of the elastic member 4 is the first direction z. The two ends of the elastic member 4 refer to the two ends of the elastic member 4 in the first direction z. The two ends of the elastic member 4 are respectively supported by the end face of the guide hole far from the guide member 1 and the abutting portion 51, so that the elastic member 4 applies a force in the direction away from the guide hole to the abutting portion 51 along the first direction z, so that the limiting member 2 and the guide member 1 approach each other in the first direction z.
[0050] Please refer to Figure 4 , Figure 5 and Figure 6, in some embodiments of the present application, the elastic member 4 is sleeved on the guide post 5. In this way, it is beneficial to improve the reliability of the installation of the elastic member 4.
[0051] Please refer to Figure 4 , Figure 5 and Figure 6 , in some embodiments of the present application, the elastic member 4 is a wave spring. The wave spring has a short length, a large stiffness, is not easily deformed, and has a small total deformation, which is beneficial to improving the guiding accuracy of the guiding channel. Of course, in some other embodiments of the present application, the elastic member 4 can also be a spring piece, a spiral spring or elastic silica gel, etc.
[0052] Please refer to Figure 4 , Figure 5 and Figure 6 , of course, in some other embodiments of the present application, the elastic member 4 can also be in a stretched state. The elastic direction of the elastic member 4 is the first direction z. The two ends of the elastic member 4 are respectively connected to the limiting member 2 and the guiding member 1 to drive the limiting member 2 and the guiding member 1 to approach each other in the first direction z.
[0053] Please refer to Figure 4 , Figure 5 and Figure 6 , in some embodiments of the present application, the guiding member 1 is provided with a connection hole, the connection hole is coaxial with the guiding hole, and the guide post 5 includes a threaded section 52, and the threaded section 52 is in threaded cooperation with the connection hole. In such a structural form, the threaded section 52 is in threaded cooperation with the connection hole, so that the guide post 5 has a plurality of installation positions in the connection hole, and the plurality of installation positions are arranged along the first direction z, so that the distance between the abutting portion 51 and the guiding hole in the first direction z is adjustable, and further the elastic compression degree of the elastic member 4 is adjustable, that is, the elastic force exerted by the elastic member 4 between the limiting member 2 and the guiding member 1 is adjustable. By adjusting the elastic force of the elastic member 4, the guiding accuracy and the smoothness of the relative movement of the movable member 3 in the movable channel d can be taken into account.
[0054] Please refer to Figure 4 , Figure 5 and Figure 6 , in some embodiments of the present application, the guide post 5 can be a screw, and the nut of the screw can be used as the abutting portion 51, and the end face of the nut close to one end of the screw rod of the screw abuts against the end face of the guiding hole. In this way, the cost of the guide post 5 is low, and the processing and manufacturing are relatively convenient.
[0055] Please refer to Figure 4 , Figure 5 and Figure 6, in some embodiments of the present application, the guiding post 5 further includes a limiting portion 53. Along the first direction z, the limiting portion 53 is located between the abutting portion 51 and the threaded section 52. The limiting portion 53 protrudes radially outward relative to the threaded section 52 along the guiding post 5, so that the limiting portion 53 can abut against the end face of the connecting hole. It can be understood that when the limiting portion 53 abuts against the end face of the connecting hole, it is difficult for the abutting portion 51 to get closer to the guiding hole, which is beneficial to reducing the risk of the elastic member 4 being crushed during the process of adjusting the elastic force of the elastic member 4.

Using the stepped screw as the guiding post 5 has a lower cost and is more convenient for processing and manufacturing. In some embodiments of the present application, the second diameter section can pass through the guiding hole, and the elastic member 4 is sleeved on the second diameter section. In this way, the second diameter section is used for abutting against the end face of the connecting hole on the one hand and for installing the elastic member 4 on the other hand. The second diameter section is fully utilized, which is beneficial to improving the structural integration degree and reducing the cost.

On this basis, in some embodiments of the present application, the number of the guiding posts 5 is at least two, and the guiding posts 5 and the elastic members 4 are arranged in one-to-one correspondence. Each guiding post 5 includes a limiting portion 53. In this way, by making each guiding post 5 include a limiting portion 53, it is beneficial to keep the maximum compression degree of the at least two elastic members 4 consistent, so as to be beneficial to making the tightness of the cooperation between each part of the moving channel d and the moving member 3 more consistent, making the guiding accuracy of each part of the moving channel d more consistent, and making the smoothness of the moving member 3 passing through each part of the moving channel d more consistent.

It can be understood that large machining errors are likely to occur on the arc surface. The mutual approach of the limiting member 2 and the moving member 3 driven by the elastic member 4 can better compensate for the machining errors of the first arc surface 11 and the second arc surface 21, which is beneficial to improving the guiding accuracy.
[0059] Please refer to Figure 5 , Figure 6 and Figure 7 , it should be explained that in this embodiment, the extension path of the moving channel d is an arc, and the axis of this arc is the same as the axis of the first arc surface 11.
