[0001] The utility model relates to the technical field of automobile accessories, in particular to a mounting structure used for connecting a plastic part with a car body sheet metal. Background Art

[0002] In the prior art, in order to connect the body sheet metal to the plastic parts, it is necessary to pre-punch multiple holes in the body sheet metal for pre-installation and limiting. At the same time, in order to adapt to the connection with the body sheet metal, the plastic parts also need to be designed with multiple structural positions for pre-installation and limiting. The design of multiple structural positions will increase the volume of the plastic parts, increase the space occupied by the plastic parts and increase the production cost. At the same time, if screws are used to connect the plastic parts and the body sheet metal, it is also necessary to add nuts to clip onto the body sheet metal. In addition, the screws will make the structure easy to slip during multiple disassembly processes.

[0003] It can be seen that in the prior art, body sheet metal is generally connected to plastic parts by clamping or screwing. When body sheet metal is clamped to plastic parts, there are disadvantages that plastic parts occupy a large space and have high production costs. When body sheet metal is connected to plastic parts by screws, there are disadvantages that the structure is easy to slip and nuts need to clamp the body sheet metal. Summary of the invention

[0005] A mounting structure for connecting a plastic part to a vehicle body sheet metal comprises an integrally formed mounting portion, a limiting portion and a clamping portion; a through hole is provided in the middle of the mounting portion; the limiting portion comprises a transverse limiting plate located above the through hole and having a groove; the clamping portion is located at the front and rear sides of the through hole; the inner surface of the groove and the clamping portion form a mounting space for accommodating screws.

[0006] Furthermore, the mounting portion is a rectangular parallelepiped structure, and long strip-shaped convex strips protruding from the upper surface are symmetrically arranged on the upper surfaces of the left and right sides.

[0007] Furthermore, the limiting portion is an axisymmetric structure, including lateral limiting plates arranged on the left and right sides of the through hole, and a transverse limiting plate connected to the lateral limiting plates.

[0008] Furthermore, the engaging portion includes a supporting portion for connecting with the mounting portion, and a pressing portion located above the supporting portion and in an inclined shape.

[0009] Furthermore, it also includes a sheet metal part and a screw; a rectangular mounting hole is opened in the middle of the sheet metal part; the mounting structure is connected to the sheet metal part through the clamping part; the screw passes through the through hole and the mounting hole and is located in the mounting space.

[0010] According to any of the above embodiments, the present invention has at least the following beneficial effects: the utility model realizes the connection between the plastic part and the sheet metal part through the integrally formed mounting part, the limiting part and the clamping part, effectively reduces the number of punching holes in the body sheet metal, saves the space of the plastic part, and saves the production cost.

[0011] In terms of structural design, the sheet metal part and the plastic part are connected by connecting the sheet metal part on one side of the mounting part and connecting the plastic part on the other side. The sheet metal part can be detachably clamped by the clamping part, and the installation space for the screw is formed, which effectively reduces the number of punching holes in the body sheet metal. The mounting structure and the mounting hole of the sheet metal part can be quickly positioned by the limiting part. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A mounting structure for connecting a plastic part to a body sheet metal, such as Figure 1 As shown, it includes an integrally formed mounting portion 110 , a limiting portion 120 and a locking portion 130 .

[0025] The mounting portion 110 is a rectangular parallelepiped structure, and the upper surfaces of the left and right sides thereof are symmetrically provided with long strip-shaped convex strips 111 protruding from the upper surface, and a through hole 112 penetrating the mounting portion is provided in the middle. In a specific embodiment, the mounting portion 110 is preferably a cubic structure, and the through hole 112 is a square through hole. The convex strip 111 is used to abut against the body sheet metal, and the through hole 112 is used as a screw mounting hole.

[0026] The shape of the limiting portion 120 is as follows: Figure 1 and Figure 3 As shown, it is an axisymmetric structure, with lateral limit plates 121 provided on the left and right sides, and a transverse limit plate 122 in a "U" shape connecting the lateral limit plates 121 on the left and right sides provided in the middle. A groove 123 is provided below the transverse limit plate 122. The two lateral limit plates 121 are used to locate the mounting holes of the sheet metal part 200, the transverse limit plate 122 is used to limit the installation depth of the screw to prevent the screw from being exposed, and the groove 123 is used for the screw to pass through. The lateral limit plates 121 are provided on the left and right sides of the through hole 112, the transverse limit plate 122 is located above the through hole 112, and the groove 123 corresponds to the through hole 112.

[0027] The engaging portion 130 is as follows Figure 4 As shown, it includes a support portion 131 for connecting with the mounting portion 110, and a pressing portion 132 located above the support portion 131 and having an inclined surface shape with a narrow top and a wide bottom. The lower end of the pressing portion 132 protrudes from the outer surface of the support portion 131. The engaging portion 130 is arranged at the front and rear sides of the through hole 112, and its back surface and the inner surface of the groove together form an installation space for the screw 300. The pressing portion 132 is elastic and can be pressed to elastically deform.

The screw 300 passes through the through hole 112 and its end is located in the groove 123. The outer diameter of the screw 300 is greater than the width of the groove 123, and the interval between the two engaging portions 130 is smaller than the outer diameter of the screw 300. During the tightening process of the screw 300, the groove 123 and the engaging portions 130 on both sides will be squeezed to a certain extent.

[0030] The mounting structure 100 is engaged with the sheet metal part 200 through the engaging portion 130, which plays the role of pre-installation and clamping. The limiting portion 120 is used to limit the drilling depth of the screw 300 to prevent the screw from being exposed. During installation, first press the engaging portion 130 to engage the engaging portion 130 with the sheet metal part 200, and then screw it in and tighten it. The utility model can be applied to the matching structure of plastic parts such as automobile bumper brackets, front and rear wheel eyebrows, A / B / C pillars and body sheet metal. It is easy to associate that the mounting structure of the utility model can be connected to other plastic parts through the lower surface of the mounting portion 110. The specific connection can be made in an integrated manner or connected by screws.
