Armrest box hinge hovering mechanism

Technical Field

The utility model relates to the technical field of automobile design and manufacture, in particular to a suspension mechanism of a hinge of an armrest box.

Background

As shown in fig. 1-2, the hinge mechanism of the armrest box in the prior art generally adopts a lower plate 1 and an upper plate 2, and is installed through a middle shaft 4, then the lower plate 1 and the upper plate 2 are linked by using a spring 3, and the lower plate 1 is fixed through the elasticity of the spring and the self limiting function, so that the hinge can realize 0-90 degrees of rotation, thereby driving the armrest box to be opened and closed. The armrest box hinge mechanism has the following technical problems:

1. over time, the spring force is insufficient, resulting in poor opening effect;

2. the damping-free hand feeling is achieved, the switching-on and switching-off values are different, and the experience feeling is poor;

3. the front end of the armrest box needs to be provided with a clamping switch.

Detailed Description

The armrest box hinge hover mechanism of the present utility model will be further described in conjunction with specific embodiments to assist those skilled in the art in a more complete, accurate and thorough understanding of the present utility model.

Example 1

As shown in fig. 3 to 5, the armrest box hinge hover mechanism of the present embodiment includes a hinge upper plate 10 and a hinge lower plate 20. The hinge upper plate 10 comprises a hinge upper plate body 11 and cantilevers 12 positioned at two sides below the hinge body 11, wherein the cantilevers at two sides are symmetrically arranged. And the cantilever 12 on both sides is provided with a first damping mounting hole 13, and the first damping mounting hole 13 is in an irregular circular shape or a polygonal shape, such as an irregular circular shape with protrusions, etc. The boom 12 has a straight arm section 14 thereon. The hinge lower plate 20 comprises a hinge lower plate body 21 and rotating arms 22 positioned on two sides above the hinge lower plate body 21, wherein the rotating arms 22 on two sides are symmetrically arranged. The rotating arm 22 is provided with a second damping mounting hole 23, and the second damping mounting hole 23 is irregularly round or polygonal, for example, irregularly round with protrusions, etc. The two side rotary arms 22 have inwardly disposed limit flanges 70, and the limit flanges 70 interfere with the straight arm segment 14 to limit when rotated to a predetermined limit position. The first damping element 40 is installed in the first damping installation hole 13 in an interference manner, and the second damping element 50 is installed in the second damping installation hole 23 in an interference manner. The first and

second damping elements

40, 50 are coaxially arranged and the cantilever 12 is connected to the rotating arm 22 by means of a bearing 30 passing through the first and

second damping elements

40, 50. The both ends of the bearing 30 are fixed by the clamping pieces 60.

In the armrest box hinge hovering mechanism, a damping element is in interference fit with a bearing, the interference can adjust the force value of the movement of an upper hinge plate and a lower hinge plate, and the bearing is assembled at a low temperature; therefore, the constant-torque switch can be realized, has damping sense and can hover at any angle.

It will be apparent to those skilled in the art that the present utility model has been described by way of example only, and that the utility model is not limited to the above-described embodiments, but is capable of numerous insubstantial modifications within the scope of the utility model as long as the inventive concept and technical solutions are adopted.
