Embodiment 1

[0055] see Figure 1 to Figure 6 , a plastic side panel for automobiles, comprising a plastic body 1 and a plurality of metal threaded inserts 3 inlaid thereon, the metal threaded inserts 3 are hollow structures, the outer walls of the metal threaded inserts 3 are in contact with the interior of the plastic body 1 For fixed connection, threads are provided on the inner cavity wall 35 of the metal threaded insert 3 to form the threaded hole 2 .

Embodiment 2

[0057] Basic content is the same as embodiment 1, the difference is:

[0058] The metal threaded insert 3 is a cone-shaped conical structure, including a narrow table 31, a wide table 32 and a truncated cone 33 between them. The narrow table 31 is flush with the inner surface of the plastic body 1, and the width The table surface 32 is flush with the outer surface of the plastic body 1 , and the frustum portion 33 is a hollow structure, and the inner wall thereof is provided with threads to form the threaded hole 2 . The diameter of the narrow mesa 31 is smaller than that of the wide mesa 32, and the taper of the truncated portion 33 is 2-5 degrees.

Embodiment 3

[0060] Basic content is the same as embodiment 2, the difference is:

[0061] At least two annular protrusions 4 are provided on the outer wall of the frustum portion 33 to be fixedly connected with the interior of the plastic body 1 . The structure of the annular protrusion 4 is one of the following two types:

[0062] The first type: the shape of the annular protrusion 4 is an annular pie shape, the bottom of the annular protrusion 4 is connected with the outer wall of the frustum part 33, and the top and side of the annular protrusion 4 are connected with the plastic The interior of the body 1 is fixedly connected, and the surface where the annular protrusion 4 is located is perpendicular to the central axis of the frustum portion 33;

[0063] The second type: the annular protrusion 4 is a hollow conical sleeve 5 , the conical sleeve 5 is arranged coaxially with the truncated portion 33 , and a plurality of slurry holes 51 are opened on the conical sleeve 5 . The ratio of...

Abstract

The invention relates to an automobile plastic lateral baffle which comprises a plastic main body and a metal threaded insert part embedded into the plastic main body, wherein the metal threaded insert part has a hollow conical circular platform structure and comprises a narrow platform surface, a wide platform surface and a conical platform part located between the narrow platform surface and the wide platform surface; the narrow platform surface is parallel and level with the inner side wall of the plastic main body; the wide platform surface is parallel and level with the outer side wall of the plastic main body; the conical platform part has a hollow structure; a thread is formed on the inner wall of the conical platform part so as to form a thread hole; and at least two annular bulges are arranged on the outer wall of the conical platform so as to fixedly connect with the interior of the plastic main body. According to the design, the connecting thread is higher in durability and assembling efficiency, the clinging of the lateral baffle and the frame is benefited, and the combining firmness of the metal threaded insert part and the plastic main body is promoted.

Description

technical field [0001] The invention relates to a side baffle, which belongs to the field of auto parts, in particular to a plastic side baffle for automobiles, which is particularly suitable for enhancing the durability of connecting threads and improving assembly efficiency. Background technique [0002] The side baffle parts of the car are located between the car frame and the leaf spring. When the leaf spring moves sideways due to bumpy road conditions, it is easy to rub and collide with the frame. Adding side baffles can protect the leaf spring and the frame, so as to Anti-friction and collision damage. In traditional automobile technology, automobile side fender parts are generally metal parts, which are designed with different thicknesses according to the vehicle load and vehicle use. At present, metal side baffle parts generally have quality problems such as heavy weight, easy corrosion and rust, insufficient wear resistance, and easy deformation. In recent years, ...
