Problems solved by technology

Usually, the left and right limit, that is, the Y-direction limit of the whole vehicle, can add a Y-direction limit buffer block in the light box area. A new type of limit block structure, the first buffer block and the second buffer block are only connected to the vehicle body through the locking pin, during use, it will cause the first buffer block and the second buffer block to rotate relatively, so that The first protruding edge and the second protruding edge cannot be reliably fitted, and the trunk lid and the side panel of the vehicle body cannot be limited to prevent shaking; and, during installation, if there is an assembly error between the first buffer block and the second buffer block , it will also cause the first convex edge and the second convex edge to be unable to fit reliably, which requires high installation accuracy
Therefore, in the actual use process, the new limit block structure cannot reliably limit the body side panels and trunk lids.

Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 8 As shown, the buffer limit structure of the trunk lid of the automobile includes a buffer block one 1 and a buffer block two 2, the buffer block one 1 and the buffer block two 2 are all cylindrical, and the buffer block one 1 is provided with holes for installing fasteners. Step hole one 1c, buffer block one 1 is installed on the side plate of the vehicle body through fasteners, and the fasteners lean against the step surface of step hole one 1c, buffer block two 2 is provided with a step hole for installing fasteners Two 2c, the buffer block two 2 is installed on the luggage compartment inner panel by a fastener, and the fastener leans against the step surface of the step hole two 2c. The buffer block one 1 is located below the buffer block two 2, the buffer block one 1 has an inclined surface 1a facing the buffer block two 2, the buffer block two 2 has an inclined surface facing the buffer block one...

Embodiment 2

[0042] This embodiment is roughly the same as the above-mentioned embodiment, the difference is that in this embodiment, the groove 1b is a number of spherical pits unevenly distributed on the inclined surface 1a, and the bump 2b is a corresponding uneven distribution There are several spherical protrusions on the inclined surface 2a, the number of grooves 1b is the same as the number of protrusions 2b, and the positions of the plurality of grooves 1b and the plurality of protrusions 2b are in one-to-one correspondence and cooperate with each other.

[0043] Both the first buffer block 1 and the second buffer block 2 are provided with only one limiting rib 4 matching the upper limit groove 3a of the mounting plate 3 .

Embodiment 3

[0045] This embodiment is roughly the same as Embodiment 1, the difference is that in this embodiment, only one groove 1b is provided on the inclined surface 1a, and only one groove 1b is provided on the inclined surface 2a to cooperate with the groove 1b. bump 2b.

Abstract

The invention belongs to the technical field of automobile bodies, and particularly relates to a buffer limiting structure of an automobile trunk lid. The buffer limiting structure solves the technical problem that an existing limiting block structure cannot reliably limit an automobile body side plate and the trunk lid. The buffer limiting structure of the automobile trunk lid comprises a first buffer block and a second buffer block, and the first buffer block is provided with a first inclined face facing the second buffer block. The buffer limiting structure is characterized in that the second buffer block is provided with a second inclined face facing the first buffer block and matched with the first inclined face, a plurality of inwards-concave grooves are formed in the first inclined face, and protruding blocks are arranged on the second inclined face in a protruding mode and embedded in the grooves. The buffer limiting structure enables the trunk lid and the automobile body side plate to be reliably limited.

Description

technical field [0001] The invention belongs to the technical field of car bodies, and in particular relates to a buffer and position-limiting structure for a trunk lid of an automobile. Background technique [0002] In addition to the load-bearing structural parts, there are many elastic components for connection on the car. Among them, the buffer block is frequently used in the body opening and closing parts system, and its main function is to limit the position and absorb energy. [0003] When the car is running, the trunk lid will respond to deformation after being stimulated by the road surface. When the deformation reaches a certain level, the edge of the trunk lid will interfere with the body and cause collisions on the side of the body or the side of the trunk lid. The paint chipping phenomenon usually occurs at the upper end of the trunk lid hinge and near the tail light box. From the position, the paint cracking at the upper end of the trunk lid hinge is caused by ...
