Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a hinge structure of an automobile instrument panel cover. Background Art

[0002] The instrument panel, also known as the dashboard, is widely used in the cabs of all vehicles and engineering machinery. It is mainly composed of instruments, steering wheels, instrument panel housings, instrument panel frames, and instrument panel wiring harnesses. In order to facilitate storage, the instrument panel is usually provided with a storage space and a cover structure that can be opened and closed.

[0003] like Figure 1 As shown, the hinges of the dashboard refrigerator and glove box cover of existing buses all use a six-link hinge assembly 4. This kind of hinge needs to open a corresponding sinking space on the dashboard during installation, which occupies a large space. When opened, the six-link hinge is exposed, resulting in an unsightly appearance and the opening and closing limit positions cannot be adjusted over a wide range. In addition, the hinge is manufactured by stamping die molding, so the minimum order quantity is large and the size cannot be changed at will to meet design requirements.

The damping value of the damping member can be adjusted by adjusting the tightness of the nut and the rotating shaft.

[0033] like Figure 3 As shown, a hinge connecting plate 13 is provided in the instrument panel body, and the fixing parts of two adjacent hinge assemblies are fixed on the hinge connecting plate so that the rotation axes of the two adjacent hinge assemblies are concentric. Figure 4 As shown, the instrument panel body is provided with a rotating arm shuttle hole 11, one end of the rotating arm is fixedly connected to the inner side of the cover plate, and the other end passes through the rotating arm shuttle hole and is rotatably connected to the fixing member through a rotating shaft.

[0034] Combination Figure 7 and Figure 8A limit assembly is provided at the connection between the exposed section and the hidden section. The rotating arm is a hook-shaped structure composed of the exposed section and the hidden section. A protective cover 36 is provided on the outer cover of the exposed section of the rotating arm. The limit assembly is used to limit the rotating arm when the cover is opened to control the opening of the cover, avoid interference with other components, and make the hidden section hidden in the instrument panel body.

[0036] The working principle of the automobile instrument panel cover hinge structure of the utility model is as follows:

[0037] When opening: open the cover 2, the cover drives the rotating arm 31 to rotate around the rotating shaft 32, the exposed section of the rotating arm passes through the rotating arm shuttle hole 11 to the outside of the instrument panel body, and is limited by the limit pin 314. The damping value of the damping member 34 is adjusted by controlling the tightening degree of the adjusting nut 35 and the rotating shaft 32, so that the cover is suspended. At this time, Figure 2 , Figure 3 and Figure 4 The open state shown;

[0038] When closing: press the cover plate 2, the cover plate drives the rotating arm 31 to rotate in the opposite direction around the rotating shaft 32, and the exposed section of the rotating arm passes through the rotating arm shuttle hole 11 into the instrument panel body, and the cover plate is buckled with the instrument panel body. Figure 6 and Figure 6 Shown in closed state.

[0039] When the opening angle of the cover needs to be changed, the position and number of the limiting holes 313 on the rotating arm can be changed to adjust the plugging position of the limiting pin 314 and the limiting hole 313 to achieve hovering of the cover at multiple opening positions.

[0040] In summary, the utility model adopts a structure in which the hinge assembly can be screwed in and out from the instrument panel body as the cover is opened and closed, and uses the space of the instrument panel body to accommodate the hinge assembly, which has a compact structure and good aesthetics; the damping value of the damping member is adjusted by adjusting the tightness of the nut and the rotating shaft, thereby achieving the cover hovering at any position without requiring moderate operating force. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
