[0026] Please refer to Figs. 1-3, as shown is the structure schematic diagram of a kind of automobile exterior assembly with blind buckle provided in an embodiment of the utility model, the automobile exterior assembly with blind buckle includes base plate 100, first carding assembly 200 and second carding assembly 300 respectively arranged on the front and rear end surfaces of the base plate 100, wherein:

[0027] In order to install the exterior part to the installation main body, the first carding piece 220 includes a square column 210, and the first carding piece 220 symmetrically arranged on both sides of the square column 210. In order to make the first carding piece 220 can be moved on both sides of the square column 210, the square column 210 is designed as a hollow structure, and a through groove 211 for the movement of the first carding piece 220 is arranged on both sides of the square column 210. At the same time, the end of the first carding piece 220 away from the base plate 100 is hard connected with the top of the through groove 211, and at the same time, by pressing the end of the first carding piece 220 close to the base plate 100, the first carding piece 220 can be slightly deformed, so that the square column 210 can enter the installation main body, and then the end of the first carding piece 220 close to the base plate 100 is clamped in the installation main body.

[0028] Further, in order to facilitate the square column 210 to be smoothly clamped into the installation main body, the first carding piece 220 includes a first inclined portion 221 and a second inclined portion 222, and the end of the first inclined portion 221 away from the second inclined portion 222 is connected to the top of the through groove 211. In this embodiment, the slope bottom of the first inclined portion 221 is smoothly connected with the side surface of the square column 210, the second inclined portion 222 is connected with the slope top of the first inclined portion 221, and the length of the first inclined portion 221 is greater than the length of the second inclined portion 222, and the included angle between the first inclined portion 221 and the side surface of the square column 210 is smaller than the included angle between the second inclined portion 222 and the side surface of the square column 210.

[0029] When the square column 210 is inserted into the installation main body, the hole edge on the installation main body extrudes the first inclined portion 221, so that the first carding piece 220 is deformed and moves towards the inside of the square column 210, and when the square column 210 enters a certain depth, the first carding piece 220 loses the extrusion of the hole edge on the installation main body, and the first carding piece 220 pops out, and then the end of the first carding piece 220 close to the base plate 100 abuts against the end surface of the installation main body, completing the assembly of the blind buckle and the installation main body.

[0030] Further, the side of the base plate 100 towards the square column 210 is recessed to form a containing groove 110 for placing a sealing member 120. The square column 210 is arranged at the center of the containing groove 110, and the containing groove 110 is provided with the sealing member 120, and the sealing member 120 is sleeved on the square column 210. When the square column 210 is inserted into the installation main body, the sealing member 120 covers the installation main body to achieve the effect of sealing or preventing abnormal sound. In this embodiment, the sealing member 120 can be rubber or sponge.

[0031] In order to clamp the outer trim part, the second clamping assembly 300 comprises a connecting column 310 fixedly connected to the base plate 100, and a second clamping part 320 arranged at the end of the connecting column 310 away from the base plate 100, and a clamping space for clamping the outer trim part is left between the connecting column 310 and the second clamping part 320. The second clamping part 320 is symmetrically provided with elastic bosses 321 on both sides of the end face close to the base plate 100. A weakening groove 322 is arranged between the elastic boss 321 and the connecting column 310.

[0032] In the embodiment, the material of the snap fastener can be POM. Taking a main positioning square snap fastener of a light truck type corner plate installed on a body side wall sheet metal as an example, the snap fastener cooperates with the corner plate: the snap fastener is installed on a snap fastener base 400 of the corner plate, the snap fastener base 400 is clamped on the connecting column 310, the snap fastener base 400 hole has a single-sided 0.1mm limiting gap with the snap fastener, the upper surface of the snap fastener base 400 needs to be designed with two 2mm high strip-shaped limiting ribs, the limiting gap is single-sided 0.1mm, the limiting ribs prevent the square column 210 from rotating, the snap fastener has a 0.5mm high boss (the pulling direction of the boss needs to be consistent with the touching direction of the first clamping part 220), and the boss is in interference fit with the snap fastener base 400, so that the snap fastener is firmly fixed on the snap fastener base 400. The boss is lifted through the weakening groove 322 beside the boss, the elasticity of the boss is improved, and the insertion force of the snap fastener is reduced.

[0033] The snap fastener cooperates with the side wall sheet metal: the 7.8mm*9.8mm square column 210 is inserted into the 8mm*10mm side wall sheet metal square hole. The sheet metal is clamped by the two first clamping parts 220 with a width of 3mm; the base plate 100 is provided with a containing groove 110 for sealing and preventing abnormal sound of the sheet metal square hole circumference; the angle of the inclined surface of the first clamping part 220 and the sheet metal square hole can control the size of the pulling force; the snap fastener has no movement in the insertion direction, and can also be a positioning surface, so as to ensure the gap and surface difference of the local snap fastener.

[0034] In summary, according to the snap fastener for assembling an automobile outer trim part provided by the utility model, the second clamping assembly is clamped on the outer trim part, the square column is inserted into the installation main body, the first clamping part on the side away from the base plate is movably connected with the square column, the other end of the first clamping part can be pressed to move on both sides of the square column, so that when the square column is clamped into the installation main body, the end of the first clamping part close to the base plate is clamped on the end face of the installation main body away from the base plate, and the installation is realized. Specifically, the first clamping assembly is clamped in the installation main body, comprising a square column and first clamping parts symmetrically arranged on both sides of the square column; the second clamping assembly is used for clamping the outer trim part, the end of the first clamping part away from the base plate is movably connected with the square column, the other end of the first clamping part is pressed to embed the first clamping part into the square column, and then the outer trim part is clamped on the installation main body.
