Problems solved by technology

[0005] However, when the outer water cut with the above-mentioned end cover and snap-in structure is installed, the end of the water cut is subjected to the outward reaction force of the sheet metal in the Y direction, which will cause the water-cut product to deform in the Y direction, and the sheet metal is subjected to the Y-direction of the end cover snap-in structure. Inward reaction force, so this kind of clamping structure is not suitable for water cutting with strong body rigidity, and the sheet metal will be scratched by the clamping structure, resulting in the appearance of the painted surface of the outer sheet metal or the decorative surface of the B / C pillar Scratches; in order to make the end self-locking mechanism smoothly turn to the sheet metal hole, sometimes the water cut is broken outwards, aligned with the sheet metal hole and then pressed, which will cause the outer water cut to deform, and the appearance of the light and shadow is not smooth. Cause surface profile to be out of tolerance

Embodiment 1

[0041] Example 1: as Figure 1-12 As shown, a self-locking mechanism is provided, the self-locking mechanism is used to cooperate with the end cap to allow the water cut to be installed on the automobile sheet metal 400 downward along the Z direction, including: a self-locking seat 100 along the self-locking seat 100 A spring piece 110, a first limit block 120 and a locking hole 140 are arranged in sequence in the length direction. One end of the spring piece 110 close to the first limit block 120 is tilted and a second limit block 130 is provided. A sheet metal locking portion 150 is formed between the limiting block 120 and the second limiting block 130 ; the self-locking seat 100 is further provided with an end cap locking unit ( Wherein, when the self-locking seat 100 is inserted into the sheet metal hole 410, the opening of the locking hole 140 is disposed upward.

[0042] Specifically, the self-locking seat 100 can be inserted into the sheet metal hole 410 along the len...

Embodiment approach

[0047] like Figure 1-10 As shown, the end cap locking unit only needs to be able to be locked together with the inserts 210 on the end cap. In the actual structure, the following embodiments may be preferred and not limited, for example:

[0048] In Embodiments 1-4, as figure 1 As shown, the end cap locking unit is set as the elastic cantilever 160, and is locked together with the insert 210 on the end cap through the hook 170. Preferably, the end cap locking unit is set as the elastic cantilever 160, and the elastic cantilever 160 is located obliquely in the locking hole 140 , one end of the elastic cantilever 160 is integrally connected with the self-locking seat 100 , and the other end of the elastic cantilever 160 is provided with a hook 170 .

[0049] The elastic cantilever 160 is arranged in an oblique shape, so when the insert 210 on the end cap is inserted into the locking hole 140 , the insert 210 can push the elastic cantilever 160 to deform. When the hook 170 is ...

Embodiment 2

[0054] Embodiment 2: as Figure 1-10 As shown, an end cap assembly is also provided, including: an end cap body 200 and a self-locking mechanism, the end cap body 200 is provided with an insert piece 210, the insert piece 210 is inserted into the locking hole 140 and locked with the end cap The unit is connected so that the end cap body 200 is fixedly connected with the self-locking seat 100 .

[0055] The end cap body 200 is fixed with the water cut, and the water cut is connected with the self-locking mechanism through the end cap body 200. When locking, the end cap body 200 is inserted into the self-locking seat 100 from top to bottom along the Z direction. During the locking process , the insert piece 210 of the end cap is inserted into the locking hole 140, and the insert piece 210 is connected with the hole wall of the locking hole 140 in a collision, thereby limiting the degrees of freedom of the insert piece 210 in the Y direction and the X direction, and the end cap l...

Abstract

The invention provides a self-locking mechanism, a self-locking seat is provided with an elastic piece, a first limiting block and a locking hole, the elastic piece is provided with a second limiting block, the self-locking seat is further provided with an end cover locking unit, the invention further provides an end cover assembly which comprises an end cover body and a self-locking mechanism, the end cover body is provided with an insertion piece, and the invention further provides an installation method of the end cover assembly. The method comprises the steps that S1, a self-locking seat is inserted into a metal plate hole of a metal plate in advance, and a locking hole is made to be in the Z direction; and S2, the inserting piece is inserted into the locking hole in the Z direction. The invention further provides a water cutting part which comprises a water cutting part body and an end cover assembly, and the invention further provides an automobile which comprises an automobile body and the water cutting part. The self-locking structure has the beneficial effects that the self-locking seat can be inserted into a metal plate hole in advance in the Y direction, the self-locking seat can provide a Z-direction locking hole for Z-direction installation of the end cover, water cutting installation is facilitated, and the problem that the end cover scratches a metal plate and a decorative face can be solved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a self-locking mechanism, an end cover assembly with the self-locking mechanism, an installation method for an end cover assembly, and an end cover assembly with the end cover assembly. The water cut also relates to a car with the water cut. Background technique [0002] The water-cut trim is an important part of the car. In the design of the water-cut, the feasibility of installing the water-cut on the vehicle needs to be considered. Usually, the water-cut is installed from top to bottom along the Z-axis of the body. To hook the sheet metal, the water cut end needs to be fixed with the door sheet metal to prevent it from coming out and warping. It is necessary to design a fixed structure at the water cut end. The specific realization form is that the outer plate single-layer sheet metal is in the Y-axis direction (left and right direction). The square hole is opened and fixed ...
