Optionally, the convex structure is semi-spherical.

Optionally, the limiting surface is provided with a groove.

Optionally, the raised structure is provided at an edge of a notch of the groove.

Optionally, the limiting surface is provided with a plurality of parallel grooves, and the number of the protruding structures between adjacent grooves is the same.

Optionally, the limiting block is a rubber limiting block.

Optionally, the stopper is configured to adapt to a bent structure at a corner of the rear bumper.

Optionally, the limiting block is provided with a mounting hole for connecting the rear bumper through a fastener.

Optionally, the limiting block is provided with a positioning column matched with the positioning hole of the rear bumper.

The utility model discloses the second aspect provides a vehicle, the vehicle includes foretell stopper.

Through the technical scheme, as the plurality of protruding structures are arranged on the limiting surface, when the back door is closed, the back door can be in point contact with the protruding structures. Therefore, when the limiting block and the back door generate relative displacement, the sliding risk can be reduced, so that the friction abnormal sound is avoided, and the NVH performance of the whole vehicle is improved.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1-5, the utility model discloses a stopper 10 sets up in rear bumper 20 of vehicle, and stopper 10 has the spacing surface towards the back door of vehicle, and spacing on the surface is provided with a plurality of protruding structures 11, and a plurality of protruding structure 11 configure to: a point contact can be made with the back door when the back door is closed.

Through above-mentioned technical scheme, owing to be provided with a plurality of protruding structures 11 on spacing surface, when the back door was closed, the back door can and protruding structures 11 between form point contact. Consequently, compare in prior art stopper and the face contact of back door the utility model discloses a stopper 10 and back door can reduce the risk of sliding when producing relative displacement to avoid producing the friction abnormal sound, improve whole car NVH performance.

In addition, because spacing being provided with a plurality of protruding structures 11 on the surface, therefore compare in the technical scheme who only sets up a protruding structure 11, the utility model discloses a stopper is when receiving the extrusion of back door, and the pressure of back door can be shared to a plurality of protruding structures 11 for have a protruding structure 11 to form the point contact with the back door all the time.

It should be understood that the raised structure 11 may be designed in a variety of shapes, such as a ball, cone, etc., so long as its tip is capable of making point contact with the back door. Optionally, the protruding structure 11 is semi-spherical.

In order to further reduce the possibility of sliding between the limiting block 10 and the back door, thereby further avoiding the generation of abnormal friction sound, optionally, the limiting surface is provided with a groove 12. Because the tip of stopper 10 is cut apart by slot 12, the flexibility of this tip has obtained the increase, consequently, when the effort that back door produced stopper 10 is greater than stopper 10's stiction, the one end that is provided with slot 12 of stopper 10 can take place earlier deformation, rather than directly taking place to slide for the back door, and only when the effort of back door continued to increase to enough big, stopper 10 could take place to slide for the back door. This arrangement can more effectively reduce the possibility of slippage between the stop block 10 and the tailgate.

In case the stop surface is provided with grooves 12, the protruding structures 11 are optionally provided at the edge of the notch of the grooves 12 in order to enable a more effective contact of the protruding structures 11 with the back door. That is, the protrusion 11 is at least the first to contact the back door when the back door presses the stopper 10. Consequently the utility model discloses a stopper 10 both realized the point contact with the back door through protruding structure 11, has reduced the friction abnormal sound, has further reduced stopper 10 and back door through slot 12 again and has taken place the possibility of sliding.

It should be understood that the number of the grooves 12 may be one or more, as long as the flexibility of the stopper 10 can be increased, in the preferred embodiment of the present invention, the plurality of grooves 12 are disposed in parallel on the stopper surface, and the number of the protruding structures 11 between the adjacent grooves 12 is the same. The parallel arrangement of the grooves 12 also minimizes the interference between the grooves 12, thereby further increasing the flexibility of the stop block 10.

The stopper 10 may be made of various elastic materials, for example, the stopper 10 is a rubber stopper.

Because when the back door is closed, more displacement, collision can take place for the back door in rear bumper 20's turning department, consequently, will the utility model discloses a stopper setting can exert its advantage of avoiding producing the friction abnormal sound as far as possible in rear bumper 20's turning department, so the utility model discloses an in the preferred embodiment, as shown in fig. 5, stopper 10 is configured as the bending structure who is adapted to rear bumper 20's turning department.

In order to facilitate maintenance and replacement, the stopper 10 may be detachably mounted to the rear bumper 20, for example, the stopper 10 is provided with a mounting hole 13 for connecting to the rear bumper 20 via a fastener. The fasteners may take many forms, such as screws, and the mounting holes 13 should be provided with threads that mate with the screws.

When the limiting block 10 is installed, in order to improve the installation efficiency and save the installation time, optionally, the limiting block 10 is provided with a positioning column 14 matched with the positioning hole of the rear bumper 20. The positioning column 14 is inserted into the positioning hole of the rear bumper 20 to indicate that the limiting block 10 is located at the mounting position, and then the mounting can be completed by inserting the fastening piece into the mounting hole 13, which is simple and convenient. In addition, in the process of inserting the fastening member into the mounting hole 13, the positioning column 14 and the positioning hole can also play a role in stably keeping the limiting block 10 at the mounting position.

The utility model also provides a vehicle, the vehicle includes foretell stopper 10. Through adopting the utility model discloses a stopper 10 can reduce the risk of sliding for the back door to avoid the friction abnormal sound, improve whole car NVH performance.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. In the technical idea scope of the present invention, it is possible to provide a solution of the present invention with a plurality of simple modifications to avoid unnecessary repetition, and the present invention is not described separately for various possible combinations. These simple variations and combinations should also be considered as disclosed in the present invention, all falling within the scope of protection of the present invention.
