[0029] It can be seen from the above description that the limiting portion 15 cooperates with the limiting protrusion 21 to limit the rotation angle of the rotating shaft 2, thereby reducing the risk of structural failure caused by excessive rotation stroke of the rotating shaft 2.

[0030] Furthermore, a buffering member for buffering the limiting protrusion 21 is provided on the limiting portion 15 .

[0031] It can be seen from the above description that the buffer component can buffer the interference force between the limiting protrusion 21 and the limiting portion 15, reducing the risk of structural failure due to hard collision between the limiting protrusion 21 and the limiting portion 15, and extending the service life.

[0032] Embodiment 1

[0033] Please refer to Figures 1 to 4, Embodiment 1 of the present invention is: a hinge mechanism with adjustable torque and multi-angle free parking, comprising a shell 1 and a rotating shaft 2, wherein the shell 1 is provided with an axial hole 11, and the rotating shaft 2 is rotatably installed in the axial hole 11, specifically, one end of the rotating shaft 2 passes through the axial hole 11, and the rotating shaft 2 is exposed and limited by one end of the shell 1 through a clamping ring 22; it also includes an adjusting component, wherein the adjusting component comprises a damping member 3, an elastic member 4 and an adjusting member 5, and the shell 1 is provided with a sliding groove 12 connected to the axial hole 11, and the damping member 3 can be slidably arranged in the sliding groove 12 and abut against the rotating shaft 2 in the axial hole 11, one end of the elastic member 4 is connected to the end of the damping member 3 away from the rotating shaft 2, and the other end of the elastic member 4 is connected to the adjusting member 5, and the The adjusting member 5 is threadedly connected to the shell 1. Specifically, the damping member 3 includes a connecting portion 31 slidably arranged in the sliding groove 12, one end of the connecting portion 31 is provided with a resisting portion 32 that resists on the side wall of the rotating shaft 2, and the other end of the connecting portion 31 is connected to the elastic member 4. A screw hole 14 for installing the adjusting member 5 is provided on the shell 1, and at least a portion of the outer side wall of the adjusting member 5 is provided with an external thread that threadably cooperates with the screw hole 14; more specifically, an adjusting hole 52 for adjusting the thread stroke of the adjusting member 5 relative to the shell 1 is provided at one end of the adjusting member 5 away from the elastic member 4; as an option, the cross-sectional shape of the adjusting hole 52 can be but is not limited to a square, a regular pentagon or a regular hexagon, and can be specifically set according to actual application requirements.

[0034] In this embodiment, a mounting portion 33 is provided at the other end of the connecting portion 31, and the elastic member 4 is installed on the mounting portion 33. It is easy to understand that the mounting portion 33 is convenient for installing the elastic member 4, while reducing the risk of the elastic member 4 falling off during operation, thereby ensuring the stability of the elastic member 4 at work. More specifically, the mounting portion 33 extends along the extension direction of the sliding groove 12, and the adjusting member 5 is provided with a limiting hole 51 extending along the extension direction of the sliding groove 12. The end of the mounting portion 33 away from the interference portion 32 can be slidably arranged in the limiting hole 51, and the limiting hole 51 can limit the moving direction of the mounting portion 33, thereby ensuring that the connecting portion 31 can slide along the extension direction of the sliding groove 12, which is beneficial to improving the structural stability; in detail, the limiting hole 51 is connected to the adjusting hole 52, so that it is convenient to avoid the mounting portion 33, which is beneficial to lengthening the sliding stroke of the damping member 3.

[0035] Optionally, the elastic member 4 is a compression spring or a disc spring sleeved on the mounting portion 33. The elastic member 4 can be selected according to actual application requirements to facilitate the expansion of development dimensions.

[0036] Optionally, the number of the elastic members 4 and the number of the adjusting members 5 are both plural, and the elastic members 4 are connected to the adjusting members 5 in a one-to-one correspondence. It is easy to understand that the resistance force of the damping member 3 on the rotating shaft 2 can be set by setting the number of the elastic members 4.

[0037] In order to facilitate the installation of the damping member 3, the housing 1 is provided with an installation groove 13 (such as Figure 3 As shown in the figure), the damping member 3 is installed in the sliding groove 12 through the installation groove 13, which is beneficial to improve the assembly efficiency.

[0038] Please combine Figure 2 In this embodiment, a limiting portion 15 is provided on the shell 1, and a limiting protrusion 21 cooperating with the limiting portion 15 is provided on the rotating shaft 2. It is easy to understand that the limiting portion 15 cooperates with the limiting protrusion 21 to limit the rotation angle of the rotating shaft 2, thereby reducing the risk of structural failure caused by excessive rotation stroke of the rotating shaft 2; specifically, the limiting protrusion 21 is provided on the rotating shaft 2 at a position outside the shaft hole 11; optionally, a buffer member (not shown) for buffering the limiting protrusion 21 may also be provided on the limiting portion 15. In this way, the risk of structural failure caused by a hard collision between the limiting protrusion 21 and the limiting portion 15 is reduced, and the service life is extended. Specifically, the buffer member may be a rubber block.

[0039] Embodiment 2

[0040] Please refer to Figure 5, Embodiment 2 of the present invention is a further improvement made to the housing 1 and the shaft 2 on the basis of Embodiment 1, and is different from Embodiment 1 in that: a limiter is provided on the shaft 2 for limiting its rotation stroke, and an arc groove 16 matching with the limiter is provided in the shaft hole 11 of the housing 1. Specifically, the limiter is a ball plunger 18, one end of the ball plunger 18 is exposed on the shaft 2 and matches with the arc groove 16, and an inclined portion 19 gradually thickened along one end thereof is provided in the arc groove 16. It is easy to understand that when the shaft 2 rotates, the exposed portion of the ball plunger 18 slides in the arc groove 16, and when When the ball plunger 18 slides to the inclined portion 19, it will be subjected to pressure from the inclined portion 19. That is to say, at this time, the greater the rotation stroke of the rotating shaft 2, the greater the pressure on the ball plunger 18. It is easy to understand that when the rotating shaft 2 is driven to rotate to a position close to its limit rotation position (that is, when the ball plunger 18 slides to the position of the inclined portion 19), under the action of the ball plunger 18, the torque of the rotating shaft 2 will increase. In this way, the turning force on the rotating shaft 2 can be buffered, reducing the risk of structural failure due to excessive force when the rotating shaft 2 rotates to its limit position, which is conducive to extending the service life.

[0041] Preferably, a blind hole 17 is further provided on the side wall of the shaft hole 11, and the blind hole 17 is connected to one end of the arc groove 16 where the inclined portion 19 is provided. It is easy to understand that when the shaft 2 is rotated, when the shaft 2 is rotated to near its limit position, the ball plunger 18 will conflict with the inclined portion 19. As the rotation stroke of the shaft 2 increases, the compression stroke of the ball plunger 18 will also increase. When the ball plunger 18 slides to the position of the maximum compression stroke, the shaft 2 continues to be rotated so that the ball plunger 18 slides into the blind hole 17. At this time, the compression stroke of the ball plunger 18 quickly returns to its original position and collides with the bottom of the blind hole 17 to generate vibration. In this way, when the shaft 2 is rotated to its limit position, the vibration generated by the collision of the ball plunger 18 with the bottom of the blind hole 17 can serve as a reminder to the user, thereby avoiding structural failure caused by excessive rotation of the shaft 2.

[0042] In summary, the hinge mechanism with adjustable torque and free parking at multiple angles provided by the present invention has the characteristics of convenient operation, simple structure, long service life, rich structural styles and strong structural stability.
