Hinge mechanism and device

Abstract

The invention provides a hinge mechanism. The hinge mechanism comprises an outer shell and a rotary shaft mechanism arranged in the inner cavity of the outer shell main body part, the outer shell mainbody part is placed on the inner cavity wall of the device body, the hinge mechanism is integrally designed to be not protruded from the device body and a door body, the occupation space is small, and the attractive appearance of the device is guaranteed. Meanwhile the rotary shaft mechanism comprises a first rotary shaft, a first sliding block, a spring assembly, a second sliding block and a second rotary shaft which are coaxially arranged, and the outer end of the first rotary shaft and the outer end of the second rotary shaft are connected with the door body. The first rotary shaft and thesecond rotary shaft are driven to rotate after the door is opened, due to the fact that the spiral directions of the outer spiral surfaces of the first rotary shaft and the second rotary shaft are opposite, the first sliding block and the second sliding block move oppositely, the spring assembly is compressed synchronously, an axial support force is provided for the first sliding block and the second sliding block, radial force overcoming the gravity of the door body is generated on the spiral arc surface and changed along with the opening and closing angle of the door, and the radial force is changed correspondingly, and thus the door keeps balance. The invention further provides a device provided with the hinge mechanism.

Description

technical field [0001] The invention belongs to the technical field of hinges, in particular to a hinge mechanism and device. Background technique [0002] With the growth of the economic level, people's living standards are getting higher and higher, and the requirements for various performances of the devices that open and close the door body around the fixed shaft are getting higher and higher. Higher requirements are put forward, and higher requirements are also put forward for the volume and appearance of the hinge mechanism. [0003] In the existing technology, such as figure 1 As shown, the hinge mechanism 03 is used to connect the door body 02 and the device body 01 , and the door body 02 can swing up and down through the hinge mechanism 03 . After opening, how to keep the door body in a stable equilibrium state within a specific angle range of opening without hand holding the door body, but only through the hinge mechanism, is a key problem studied by those skille...

Problems solved by technology

[0004] In addition, the traditional hinge mechanism also has the following defects: During long-term use, the performance of the internal spring decreases, which also reduces the service life of the hinge; , Transportation takes up a certain amount of space, the appearance is not beautiful, and takes up a lot of space; when the door is closed, the speed is too fast, and it is easy to pinch hands; since the hinge components are almost all steel parts, it is easy to produce abnormal noise due to friction
