Deformable clamping structure

Abstract

The invention provides a deformable clamping structure which comprises a buckling piece and a clamping piece, the buckling piece comprises a supporting part, an elastic limiting part and a clamping hook part, the elastic limiting part and the clamping hook part are arranged on the supporting part, a via hole is formed in the connecting position of the elastic limiting part and the supporting part, the clamping hook part is located at the via hole, and a first guide face is arranged on the side, opposite to the via hole, of the clamping hook part; the clamping piece comprises a base part and a clamping tongue arranged on the base part, the clamping tongue is provided with a clamping groove used for being matched with the clamping hook part, and the end, away from the base part, of the clamping tongue is provided with a second guide face used for being matched with the first guide face; when the clamping tongue is stressed to be inserted into the through hole, the first guide face and the second guide face are attached and apply pressure, the clamping tongue and the elastic limiting part are stressed to elastically deform so that the clamping tongue can penetrate through the through hole, the clamping hook part can be inserted into the clamping groove, and the elastic limiting part abuts against the side wall of the base part. According to the deformable clamping structure, the problems that when a mold stripping negative angle exists on the modeling surface of the clamping area, the clamping structure cannot be arranged, or clamping is not firm, and the appearance quality is poor can be solved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a deformable clamping structure. Background technique [0002] At present, automobile OEMs are paying more and more attention to aerodynamics, and often set some air ducts in the front bumper, rear bumper, D-pillar and other positions to reduce wind resistance and achieve the purpose of optimizing aerodynamics. Taking the air channel at the position of the front bumper as an example, the air channel components need to be clamped with the front bumper. When there is no negative angle on the modeling surface (CAS surface) of the clamping area, the conventional hook and slot The matching structure can realize the clamping connection between the air passage part and the front bumper, and the gap surface difference at the joint between the two can also be better controlled. [0003] However, when there is a negative angle in the shape surface (CAS surface) of the clamping area, the clamping...

Problems solved by technology

[0004] In view of this, the object of the present invention is to provide a deformable clamping structure, which can at least solve the problem in the prior art that the clamping structure cannot be arranged when the molding surface of the clamping area has a negative angle of drawing, or the clamping is not correct. Technical problems of reliability and poor appearance quality
