For example, in the case of application to a vehicle panel, the vehicle panel is usually provided in a reversible structure, the front end of which is fixed to, for example, a rear box side trim, and the rear box side trim is mounted on a sheet metal, and the entire dimensional chain is long, and therefore the requirement for the positioning structure of the panel is high. When the rear deck lid is closed, the coat and hat plate may collide with the rear deck lid and generate noise. As a part of the positioning structure of the coat panel, the buffer device, which is disposed at the rear end of the coat panel, can absorb impact force and noise during collision well.

Drawings

The invention is explained in more detail with reference to the drawings, in which:

fig. 1 shows a schematic perspective view of a damping device according to the invention;

fig. 2 shows a cross section of the damping device according to fig. 1;

fig. 3 shows a damping device according to the invention fitted at a coat panel.

Detailed Description

It is easily understood that, according to the technical solution of the present invention, a person skilled in the art can propose various alternative structural modes and implementation modes without changing the essential spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.

Fig. 1 shows a damping device 1 according to an aspect of the invention in a perspective view. The damping device 1 comprises a body 11, a root 12 and a neck 13 arranged therebetween, said body 11 and root 12 being connected together by means of the neck 13. The root 12 serves, for example, for fastening the damping device 1 in an insertion manner in the hatboard 2 shown in fig. 3. Of course, the root 12 can also be provided with a thread for screwing into a corresponding component, for example a coat panel. In the assembled state, the root 12 with the neck 13 engages into the respective component.

It can also be seen from fig. 1 that a bore hole 111 is also provided in the body 11 of the impact absorbing device for making it easier for the body to absorb impact forces by deforming during a collision, so that a better cushioning effect is achieved. The configuration of the bore 111, including the depth (through or non-through) and the cross-sectional shape, can be tailored to the specific situation. In the embodiment shown in fig. 1, the bore 111 can be provided as a through-bore and has an oval cross section.

In order to reinforce the damping device in such a way that it does not plastically deform (i.e. excessively press-deform) if the damping requirements are met, a reinforcement rib 112 is also arranged in the bore hole 111, in particular in the middle of the bore hole 111, in conjunction with fig. 2. Alternatively, the reinforcing beads 112 can be arranged in the direction in which external forces are applied during a collision. For example, in the case of use in a coat panel 2, the damping device 1 according to the invention is arranged at the rear of the coat panel, more precisely at a location close to the rear deck lid (see fig. 3), which collides with the damping device 1 and exerts an external force forward from behind the vehicle when the deck lid is closed. In fig. 1, the ribs 112 are arranged along the long sides of the ellipse. The reinforcing ribs 112 are arranged in the direction in which the external force is applied, so that the hardness of the cushioning device 1 can be improved more. Alternatively, the reinforcing ribs 112 can have an i-shaped cross-section.

In addition, the body 11 of the shock absorber is provided with an outwardly protruding arc-shaped portion 113 at a portion subjected to the external force, that is, the portion is subjected to a rounding process. The body 11 is better able to resist crush deformation during a collision, preventing excessive deformation and damage to the cushioning device, compared to an angled or right-angled profile.

During assembly, the damping device 1 is fixed, for example in an inserted manner, by means of the root 12, the root 12 and the neck 13 being of higher hardness than the body 11. Optionally, the neck 13 is rounded in correspondence with the transition between the body 11 and the root 12, in order to prevent the neck 13 from breaking during a collision, see fig. 2.

Alternatively, the body 11 of the damping device can be made of a flexible material with a damping, for example rubber, in order to absorb energy during a collision.

Furthermore, the present invention also includes a vehicle having a damping device according to any one or more of the embodiments described above, the technical features and technical effects thereof being similar to the above description, and therefore not being described in detail herein.

It should be understood that all the above embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon reading the teachings of the present invention, are intended to be within the scope of the appended claims.
