Example 1

The embodiment of the utility model provides a hinge structure, including mutual articulated first connecting piece 10 and second connecting piece 20, its characterized in that, the articulated department of first connecting piece 10 and second connecting piece 20 is formed with the damping chamber, is provided with damping component 40 in the damping chamber, and damping component 40 includes friction disc 41 and elastic component 42, and elastic component 42 is in compression state and supports friction disc 41 tightly in the target chamber wall of damping chamber in the damping chamber, and the target chamber wall is the surface that first connecting piece 10 or second connecting piece 20 correspond to the damping chamber.

Specifically, referring to fig. 1 to 3 of the drawings, the present invention is mainly designed and improved for the damping portion of the hinge structure, so as to improve the durability of the hinge structure in the long-term use. Particularly, the present invention uses the friction plate 41 and the elastic member 42 engaged with the friction plate 41 to form the damping assembly 40 together, and the damping assembly 40 is disposed in the relatively closed damping cavity between the first connecting member 10 and the second connecting member 20 hinged to each other, and the elastic force of the elastic member 42 can be used to push the friction plate 41, so that the friction plate 41 is pushed to move when the friction plate 41 is worn to compensate the interference lost due to the wear, thereby ensuring the constancy of the interference for realizing the damping function; the elastic force of the elastic member 42 acts on the friction plate 41 to increase the static friction force of the friction plate 41, thereby improving the damping effect.

When the damper is used specifically, the friction plate 41 and the elastic member 42 are abutted against each other and are arranged in the damper cavity, the elastic member 42 is in a compressed state and enables the friction plate 41 to abut against a target cavity wall on one side of the damper cavity, the target cavity wall may be a surface of a portion of the first connecting member 10 or the second connecting member 20 enclosing the damper cavity, that is, the friction plate 41 may abut against the first connecting member 10 or the second connecting member 20. Preferably, the friction plate 41 abuts against the active moving part in the hinge structure, i.e. the second connecting member 20 connected to the fan head 30 in this embodiment, as shown in fig. 2, so that the whole damping assembly 40 and the first connecting member 10 (the supporting part connected to the fan) are kept relatively static and the structure is more stable. When the friction plate 41 is worn, the elastic member 42 pushes the friction plate 41 to move toward the second connecting member 20 in the present embodiment and to abut against the surface of the second connecting member 20, so that the magnitude of interference lost due to wear is compensated, thereby achieving that the damping function is always kept effective. In addition, utilize the compensation function of elastic component 42 to the interference of friction disc 41, the utility model discloses a problem of the assembly interference deviation that friction disc 41 size machining error arouses can also be solved to the damping structure.

The pushing member 43 is mainly used to achieve the stability of the damping structure and the guidance of the elastic force of the elastic member 42; because the elastic member 42 and the friction plate 41 (usually, a completely rigid structure or material is not adopted) are not rigid structures, a pushing member 43 with a rigid structure needs to be added to the structure to improve the strength and stability of the structure of the damping assembly 40; and the pushing piece 43 can be in sliding fit with the cavity wall of the damping cavity, so that the deformation of the elastic piece 42 in other directions can be limited, and the direction guiding effect on the elastic force of the elastic piece 42 is realized.

Preferably, the side surface of the pushing member 43 is attached to the side surface of the friction plate 41, so that the pushing member 43 can completely press the friction plate 41, thereby enabling the friction plate 41 to be uniformly stressed at each position and tightly press the corresponding cavity wall of the damping cavity, enabling the area of the side surface of the pushing member 43 to be not smaller than that of the side surface of the friction plate 41, and enabling the projection of the side surface of the friction plate 41 to completely fall within the range of the side surface of the pushing member 43.

And the assembly depth of the fastener 60 and the connecting hole is fixed (when the fastener 60 is assembled in place, the limiting structure on the fastener 60 abuts against the end face of the pin 50), and only the fastener 60 needs to be screwed during assembly without specially controlling the assembly depth. Whereas the prior art utilizes the depth of assembly of the fastener 60 to control interference, it requires special control of the depth of assembly of the fastener 60.
