The present application does not limit the specific structure of the clamping member 23, and reference is made to only two specific structures, which are described in detail in the first embodiment and the second embodiment.

The first embodiment is as follows: referring to fig. 3 to 10, the clip member 23 includes a first deformation portion 231 and a first clip portion 232, the first deformation portion 231 is formed by extending from the upper end of the extension plate 22 to the outside and downward direction, and the first clip portion 232 is formed at the lower end of the first deformation portion 231; when the first deformation portion 231 is inserted into the mounting hole 201, the first deformation portion 231 is deformed inward until the first clamping portion 232 moves to the mounting hole 201, and the first deformation portion 231 is deformed again, so that the first clamping portion 232 is forced to be clamped on the inner wall of the mounting hole 201. The clamping piece 23 of the structure has high strength, the stability of the mutual connection between the plaque 100 and the automobile sheet metal 200 can be fully ensured, and meanwhile, the clamping piece 23 is simpler in structure and more convenient to process.

Referring to fig. 5 and 8-10, in the first embodiment, the first clamping portion 232 is formed along the front side and/or the rear side of the lower end of the first deformation portion 231 to extend inward and downward. On one hand, the first clamping portion 232 machined and formed in the mode is not prone to deformation in the using process, so that the strength of the first clamping portion 232 can be fully improved, and the stability of mutual clamping between the first clamping portion 232 and the mounting hole 201 is guaranteed; on the other hand, when the assembly, only need make first deformation portion 231 inwards take place deformation to can normally joint first joint portion 232 in installing hole 201, can not influence the installation. In addition, since the first clamping portion 232 is formed at the front and/or rear side of the first deformation portion 231 and the first deformation portion 231 is formed to extend outward and downward along the upper end of the extension plate 22, the first clamping portion 232 is located at the front and/or rear side of the extension plate 22, that is, when the first deformation portion 231 is deformed inward, the first clamping portion 232 and the extension plate 22 do not interfere with each other.

Referring to fig. 6 and 10, in the first embodiment, in some embodiments of the present application, a limiting portion 221 is formed on the extending plate 22 in an outward extending manner, and the automobile sheet metal 200 is suitable to be clamped between the limiting portion 221 and the first clamping portion 232. When inserting joint spare 23 into mounting hole 201, when spacing portion 221 and car panel beating 200 contact, first joint portion 232 joint in mounting hole 201, and press from both sides tight car panel beating 200 between first joint portion 232 and the spacing portion 221 to the inside direction removal of first joint portion 232 continuation to mounting hole 201 has improved the stability of mutual joint between first joint portion 232 and the mounting hole 201.

Referring to fig. 5 and 10, in the first embodiment, at least one folded edge 2312 is formed between the upper end and the lower end of the first deforming part 231 by bending inward. Under the action of the folding edge 2312, the strength of the position, close to the folding edge 2312, on the first deformation part 231 is improved, namely the position, close to the folding edge 2312, on the first deformation part 231 is not easy to deform; similarly, under the effect of the first clamping portion 232, the strength of the position, close to the first clamping portion 232, of the first deformation portion 231 (i.e., the lower end of the first deformation portion 231) is improved, that is, the position, close to the first clamping portion 232, of the first deformation portion 231 is not easily deformed; that is, the position of the first deformation portion 231, which is easily deformed, is most easily deformed at the upper end of the first deformation portion 231, i.e., the position of the first deformation portion 231, which is close to the extension plate 22; in addition, as the first deformation part 231 is formed by extending outwards and downwards along the upper end of the extension plate 22, in the assembling process, when the first deformation part 231 is inserted into the mounting hole 201, the inner wall of the mounting hole 201 forces the upper end of the first deformation part 231 to deform inwards, i.e. the required inserting force is small, and the assembly is more convenient; after the assembly, the position that the lower extreme and the middle part of first deformation portion 231 were equipped with hem 2312 all is difficult for taking place deformation, and first deformation portion 231 is difficult for taking place crooked deformation promptly, has further improved the stability of mutual joint between first joint portion 232 and the mounting hole 201.

Referring to fig. 5, 7, 8 and 10, in the first embodiment, a gap 2311 is provided between the first deformation portion 231 and the extension plate 22. Under the effect of breach 2311, the position (the upper end of first deformation 231) that is close to breach 2311 on the first deformation 231 takes place deformation more easily to can cooperate hem 2312, further reduce the insertion dynamics that first deformation 231 inserted mounting hole 201.

The extension plate 22 with the structure is simpler in structure and more convenient to process; in addition, the contact area between the two abutting sections 223 is increased, thereby improving the strength of the extension plate 22; in addition, the empty space between the first deformation portion 231 and the extension plate 22 is increased, thereby providing enough space for the first deformation portion 231 to be deformed inward, preventing interference.

The second embodiment: referring to fig. 11-19, the upper ends of the two extension plates 22 are bent inward to form bent segments 224, and the ends of the two bent segments 224 are abutted against each other, so as to limit the two extension plates 22 from deforming in the opposite direction; the tail end of at least one bending section 224 extends to form a pressing edge section 225, and the pressing edge section 225 is pressed on the other bending section 224, so that the two bending sections 224 are limited to be separated from each other; the extending plate 22 is provided with a through hole 226 in a penetrating way; the engaging member 23 includes a second deforming part 233 and a second engaging part 234, the second deforming part 233 is formed along the upper sidewall of the through hole 226 to extend outward and downward, and the second engaging part 234 is formed at the lower end of the second deforming part 233. As shown in fig. 13, 14 and 15, the extension plates 22 of this structure are abutted against each other by the ends of the bent segments 224, so that deformation of the two extension plates 22 in the opposite direction can be restricted; meanwhile, under the action of the crimping sections 225, namely, the crimping section 225 on one bending section 224 is crimped on the other bending section 224, so that the two bending sections 224 (i.e. the two extension plates 22) can be limited from being separated from each other. In addition, the second deformation portion 233 and the second clamping portion 234 can be directly formed by punching the extension plate 22, so that the processing is more convenient.

Referring to fig. 14 and 19, in the second embodiment, the second clamping portion 234 is formed by bending the lower end of the second deformation portion 233 inwards and then downwards; the outer side of the second engaging portion 234 is provided with a groove 2341. The second clamping part 234 has simpler structure and more convenient processing; in addition, under the effect of cooperation recess 2341, the dynamics of the mutual joint between second joint portion 234 and the mounting hole 201 has further been increased to increased the degree of difficulty that second joint portion 234 breaks away from mounting hole 201, the stability of mutual joint is higher between second joint portion 234 and the mounting hole 201 promptly.

It is understood that the positioning slot 14 can also be disposed on the supporting plate 21, and the operation principle is the same, which is not described herein.

The detachable mounting manner between the mounting seat 1 and the trim panel 100 is not limited in the present application, for example, as shown in fig. 3 and 4 (or fig. 11 and 12), a clamping seat 101 is provided on the back surface of the trim panel 100, and a first slide 102 is provided on the clamping seat 101; a second slideway 11 is arranged on the mounting seat 1 or formed between the mounting seat 1 and the supporting plate 21; a clamping block 12 protrudes in the second slide way 11, and a clamping groove 103 is recessed in the first slide way 102. As shown in fig. 7 and 8 (or fig. 16 and 17), when the second slideway 11 slides to the end of the first slideway 102, the latch 12 is latched to the latching slot 103, so as to limit the relative displacement between the latching seat 101 and the mounting seat 1. Through the sliding connection between the first slide way 102 and the second slide way 11, the assembling precision between the installation seat 1 and the clamping seat 101 (i.e. the plaque 100) can be improved. Through the clamping fit between the clamping block 12 and the clamping groove 103, the first slide way 102 and the second slide way 11 can relatively slide, so that the installation between the installation seat 1 and the clamping seat 101 (namely the plaque 100) is realized; when the installation seat 1 is forcibly slid in the opposite direction by the action of external force, the latch 12 is forced to disengage from the latch slot 103, thereby realizing the detachment between the installation seat 1 and the latch seat 101 (i.e., the plaque 100). It should be noted that the positions of the latch 12 and the latch slot 103 may be interchanged, that is, the latch 12 is in the first slide 102, and the latch slot 103 is in the second slide 11.

Referring to fig. 11, 16 and 17, in some embodiments of the present application, the mounting base 1 is provided with a hook 13, and when the latch 12 is connected to the latch slot 103, the hook 13 is connected to the connecting base 101, so as to limit the separation of the latch 12 from the latch slot 103. When the fixture block 12 is clamped in the clamping groove 103, that is, when the second slideway 11 slides to the tail end of the first slideway 102, the second slideway 11 and the first slideway 102 cannot slide further, that is, when the mounting base 1 is further slid, the fixture block 12 cannot be separated from the clamping groove 103; and because the hook 13 is clamped in the clamping seat 101 when the latch 12 is clamped in the clamping groove 103, when the mounting seat 1 is slid in the opposite direction, the hook 13 limits the latch 12 from being separated from the clamping groove 103, thereby ensuring the stability of the connection between the mounting seat 1 and the clamping seat 101 (i.e. the decoration plate 100). In addition, when the mounting base 1 needs to be dismounted, the clamping hook 13 is forced to deform by external force, so that the clamping hook 13 is separated from the clamping base 101, and the mounting base 1 can be slid reversely to realize dismounting.
