Referring to fig. 1 to 3, a damping device 100 according to an embodiment of the present invention includes a clamping body 10 and an adjusting assembly 20. The clamping body 10 comprises a fixed part 11 and a movable part 12 which are positioned at two opposite ends of the clamping body 10, and a connecting part 13 which connects the fixed part 11 and the movable part 12, wherein the connecting part 13, the fixed part 11 and the movable part 12 jointly enclose a containing space 14 for containing the rotating shaft 71, and the movable part 12 and the fixed part 11 are opposite at intervals and form a gap 15 which is communicated with the containing space 14. The adjusting assembly 20 comprises an adjusting piece 21, the adjusting piece 21 can be rotatably arranged on the fixing portion 11 and the movable portion 12 in a penetrating mode, and when the adjusting piece 21 rotates relative to the clamping body 10, the adjusting piece 21 can drive the movable portion 12 to move so as to adjust the size of the gap 15, and therefore the clamping force between the clamping body 10 and the rotating shaft 71 can be adjusted.

When the adjusting member 21 drives the movable portion 12 to move toward the fixed portion 11, the gap 15 (the distance between the movable portion 12 and the fixed portion 11) is reduced, so as to increase the contact area between the clamping body 10 and the rotating shaft 71 and the clamping force between the clamping body 10 and the rotating shaft 71. When the adjusting member 21 drives the movable portion 12 to move in a direction away from the fixed portion 11, the gap 15 (the distance between the movable portion 12 and the fixed portion 11) increases, so as to reduce the contact area between the clamping body 10 and the rotating shaft 71 and the clamping force between the clamping body 10 and the rotating shaft 71. Since the clamping force between the clamping body 10 and the rotating shaft 71 is proportional to the magnitude of the damping between the clamping body 10 and the rotating shaft 71, that is, the larger the clamping force between the clamping body 10 and the rotating shaft 71 is, the larger the damping between the clamping body 10 and the rotating shaft 71 is; the smaller the clamping force between the clamping body 10 and the rotating shaft 71, the smaller the damping between the clamping body 10 and the rotating shaft 71.

The damping device 100 of the embodiment of the invention can adjust the clamping force between the clamping body 10 and the rotating shaft 71 through the adjusting assembly 20, so as to adjust the damping between the clamping body 10 and the rotating shaft 71, therefore, a user can select the damping suitable for the hand feeling of the user according to the requirement, and the user experience is improved.

The connecting portion 13 is located between the fixed portion 11 and the movable portion 12 and connects the fixed portion 11 and the movable portion 12, and the connecting portion 13, the fixed portion 11 and the movable portion 12 together enclose an accommodating space 14 for accommodating the rotating shaft 71. The movable portion 12 is opposed to the fixed portion 11 with a space therebetween, and a gap 15 communicating with the housing space 14 is formed. The connecting portion 13 includes an inner wall 131 near the accommodating space 14, and the inner wall 131 defines an accommodating groove 132 surrounding the center of the accommodating space 14. The connecting portion 13 may be made of a flexible material including rubber. In this embodiment, the clamping body 10 may be an integrally formed structure, that is, the fixed portion 11, the movable portion 12, and the connecting portion 13 are an integral structure. In other embodiments, the clamping body 10 may be a separate structure, for example, the fixing portion 11, the movable portion 12 and the connecting portion 13 of the clamping body 10 are all a single structure and are connected together by a connecting member. In the present embodiment, the housing space 14 is substantially C-shaped, and the gap 15 is a C-shaped notch. In other embodiments, the shape of the receiving space 14 may be other arc shapes. It will be appreciated that the three parts of the clamping body 10 may also be of a two-part construction connected to each other.

The adjusting assembly 20 includes an adjusting member 21, a locking member 22, an elastic member 23, an adjusting nut 24, and a blocking member 25.

The adjusting nut 24 is cylindrical, the adjusting nut 24 is rotatably mounted in the nut mounting hole 124, and the adjusting nut 24 has a through hole (not shown) along a radial direction, and the through hole is a threaded hole. When the adjustment nut 24 is mounted in the nut mounting hole 124, the axis of the through hole, the axis of the movable portion mounting hole 123, and the axis of the fixed portion mounting hole 113 are aligned.

The adjusting member 21 includes a knob 211 and a rod 213. The knob 211 and the rod 213 may be cylindrical, and the diameter of the knob 211 is larger than that of the rod 213. The knob 211 comprises a knob bottom surface 212, a rod body 213 is formed by extending from the knob bottom surface 212, and an external thread is formed at one end of the rod body 213 far away from the knob. The rod 213 is rotatably inserted into the fixed portion mounting hole 113 and the movable portion mounting hole 123, and specifically, one end of the rod 213, which is away from the knob 211, is inserted into the fixed portion mounting hole 113, the movable portion mounting hole 123, and the through hole in this order and screwed into the through hole. The rod 213 has a blocking member mounting hole 215 along a radial direction, and when the adjusting member 21 is inserted into the holding body 10, the blocking member mounting hole 215 is located between the fixing portion 11 and the knob 211. The blocking member 25 is installed in the blocking member installation hole 215, the elastic member 23 is sleeved on the rod body 213 and located between the knob 211 and the blocking member 25, and the elastic member 23 abuts against the blocking member 25. The stop 25 may be a pin, screw, or a combination of a screw and a nut. The elastic member 23 may be a spring, an elastic sleeve, or the like.

The locker 22 is detachably installed in the locking hole 171. When the adjusting member 21 is inserted into the clamping body 10 and the clamping force between the clamping body 10 and the rotating shaft 71 is adjusted, the locking member 22 is rotated to make the locking member 22 abut against the rod 213, so as to limit the rotation of the rod 213. When the adjusting member 21 is inserted into the clamping body 10 and the clamping force between the clamping body 10 and the rotating shaft 71 needs to be adjusted, the locking member 22 is rotated to separate the locking member 22 from the rod 213 so as to allow the rotation of the rod 213. The retaining member 22 may be a retaining screw.

Referring to fig. 4 and 5, the damping member 30 is accommodated in the accommodating groove 132 and contacts with the rotating shaft 71. In the present embodiment, the Damping member 30 includes Damping grease (Damping grease), which is high-resistance grease prepared by adding additives such as rust-proof, waterproof, and corrosion-resistant additives to the special polymer base oil and the high-purity thickener. In other embodiments, the damping member 30 further comprises rubber.

The limiting member 40 is detachably mounted on the adjusting member 21 and can abut against the movable portion bottom surface 122. Specifically, the limiting element 40 is a nut, and when the adjusting element 21 is inserted into the clamping body 10, the limiting element 40 is located on a side of the movable portion 12 away from the fixed portion 11, and meanwhile, the limiting element 40 is located on a side of the rod 213 away from the knob 211 and is screwed with the rod 213.

When the knob 211 is rotated, the knob 211 drives the rod 213 to rotate relative to the clamping body 10 and the adjusting nut 24, and the rod 213 and the adjusting nut 24 rotate relative to each other to move the adjusting nut 24 along the axial direction of the rod 213. When the fixing portion 11 and the adjusting member 21 can only rotate relative to each other and can not move relative to each other, the adjusting nut 24 can move along the axis of the rod 213, so that the adjusting nut 24 drives the movable portion 12 to move relative to the fixing portion 11 (including moving in a direction away from the fixing portion 11 and moving in a direction close to the fixing portion 11). When the adjusting nut 24 drives the movable portion 12 to move toward the fixed portion 11, the gap 15 (the distance between the movable portion 12 and the fixed portion 11) is reduced, so as to increase the contact area between the clamping body 10 and the rotating shaft 71 and increase the clamping force between the clamping body 10 and the rotating shaft 71. When the adjusting nut 24 drives the movable portion 12 to move away from the fixed portion 11, the gap 15 (the distance between the movable portion 12 and the fixed portion 11) is increased, so as to reduce the contact area between the clamping body 10 and the rotating shaft 71 and reduce the clamping force between the clamping body 10 and the rotating shaft 71. Damping exists between the clamping body 10 and the rotating shaft 71, and the clamping force between the clamping body 10 and the rotating shaft 71 is in direct proportion to the damping, that is, the larger the clamping force between the clamping body 10 and the rotating shaft 71 is, the larger the damping between the clamping body 10 and the rotating shaft 71 is; the smaller the clamping force between the clamping body 10 and the rotating shaft 71, the smaller the damping between the clamping body 10 and the rotating shaft 71.

The damping device 100 of the embodiment of the present invention also has the following advantageous effects: first, in the damper device 100, the damper 30 is provided between the connection portion 13 and the rotation shaft 71, so that the wear of the clamp body 10 can be reduced to prolong the life of the clamp body 10, and the rotation shaft 71 can smoothly rotate in the housing space 14.

Secondly, in the damping device 100, the adjusting nut 24 combined with the adjusting part 21 is arranged in the movable part 12, so that when the adjusting part 21 rotates relative to the adjusting nut 24, the adjusting nut 24 can drive the movable part 12 to move towards the direction close to the fixed part 11 or move towards the direction far away from the fixed part 11; meanwhile, when the movable portion 12 moves relative to the fixed portion 11, even if the axis of the movable portion mounting hole 123 and the axis of the fixed portion mounting hole 113 are offset (the axis of the movable portion mounting hole 123 and the axis of the fixed portion mounting hole 113 are not on the same straight line), since the adjusting nut 24 can rotate relative to the movable portion 12, the offset of the axis of the adjusting member 21 can be reduced so that the axis of the adjusting member 21 and the axis of the fixed portion mounting hole 113 always remain substantially coincident.

Third, in the damper device 100, the stopper 40 is provided on the adjuster 21 on the movable portion bottom surface 122 side, so that the movable portion 12 does not come off the adjuster 40 when the movable portion 12 moves in a direction away from the fixed portion 11.

Fourth, the damping device 100 is provided with the locking member 22 capable of abutting against the adjusting member 21, so that after the adjustment of the clamping force between the clamping body 10 and the rotating shaft 71 is completed, the locking member 22 can limit the rotation of the rod 213 to avoid the situation that the clamping force between the clamping body 10 and the rotating shaft 71 is changed in case of misoperation, and thus the unwanted damping of the user can be obtained.

In some embodiments, the damper device 100 of the above embodiments may not be provided with the damper 30, and in this case, the inner wall 131 of the connecting portion 13 may directly abut against the rotating shaft 71, and the inner wall 131 may not have the receiving groove 132.

In some embodiments, the damping device 100 of the above embodiments may not be provided with the adjusting nut 24, in this case, the movable portion mounting hole 123 is a threaded hole, the rod body 213 is directly connected to the movable portion mounting hole 123 by a threaded connection, and when the rod body 213 rotates relative to the movable portion 12, the movable portion 12 moves along the axis of the rod body 213 to adjust the size of the gap 15.

In some embodiments, the blocking member 25 of the adjusting assembly 20 is not limited to the above embodiments, and the blocking member 25 may also be a structure directly extending from the peripheral wall 214 of the rod 213, and the elastic member 23 is sleeved on the rod 213 and interferes with the blocking member 25. The elastic member 23 is located between the blocking member 25 and the knob 211. In this case, the blocking member 25 may be a step formed on the peripheral wall 214 of the rod 213, and the adjusting member 21 may be a separate structure, for example, the rod 213 and the knob 211 are separate structures, and the rod 213 and the knob 211 may be connected together by means of a snap fit or a screw connection.
