Description

A heavy duty commercial truck plastic bumper bracket

technical field

The invention belongs to the technical field of truck bumpers, in particular to a plastic bumper bracket for heavy-duty commercial trucks.

Background technique

The bumper brackets of heavy-duty commercial trucks are mostly composed of sheet metal stamping and welding or pipe beam welding and stamping metal pressing parts. There are several defects: 1. There are many processes and low production efficiency; Car appearance; 3. Low dimensional accuracy, poor fit between the bumper and surrounding components, resulting in difficult installation and poor protection. Therefore, brackets made of non-metallic materials are required to effectively reduce the weight of parts, improve fit accuracy, and achieve lightness of the vehicle Quantify.

Contents of the invention

In order to solve the above problems, the present invention discloses a plastic bumper bracket for heavy-duty commercial trucks, which is light in weight, low in cost, simple in assembly and capable of reducing the weight of the bumper.

To achieve the above object, the technical scheme of the present invention is as follows:

A plastic bumper bracket for a heavy-duty commercial truck has an integral structure, and is formed by injection molding of long glass fiber reinforced polypropylene material at one time. The long glass fiber fibers are interwoven with each other, and the strength is higher, which can replace metal parts.

The bumper bracket is composed of the main body of the bumper bracket and the vertical fixing surface of the bumper bracket. The inner periphery of the main body of the bumper bracket is fully surrounded by double-layer ribs, and the interior adopts a radial rib structure. The main body of the bumper bracket adopts an equal-strength beam structure. The root and end of the main body of the bumper bracket are provided with bumper fixing holes. Hole two, bumper fixing hole one, bumper fixing hole two built-in embedded nuts.

The beneficial effects of the present invention are:

The plastic bumper bracket of a heavy-duty commercial truck according to the invention is directly molded by one-time injection molding of high-performance non-metallic materials, has high strength, light weight, high dimensional accuracy, precise installation, and greatly improves production efficiency.

detailed description

The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

As shown in the figure, a plastic bumper bracket for a heavy-duty commercial truck according to the present invention is used for the front bumper of a car. The bracket includes a bumper bracket main body 1 and a bumper bracket vertical fixing surface 2. The inside of the bumper bracket main body 1 The periphery adopts a double-layer rib full-enclosed structure 3, and the interior adopts a radial reinforcing rib structure 4. The ribs are connected to each other, and an equal-strength beam structure is adopted from the root to the end. The root and end of the bumper bracket main body 1 are provided with insurance. Bar fixing hole 1 6, the vertical fixing surface of the bumper bracket is provided with intersecting rib structure 8, the vertical fixing surface 2 of the bumper bracket is provided with bumper fixing hole 2 5, bumper fixing hole 1 6, bumper fixing hole 2 5 built-in embedded nut 7.

The plastic bumper bracket of a heavy-duty commercial truck according to the present invention, when in use, the bumper bracket passes through the bumper fixing holes 6 at the root and end of the bumper bracket main body 1, and is fixed on the bumper 11 to form a bumper assembly , the bumper assembly is installed on the vehicle frame through the bumper fixing hole 5, the mutual cross rib structure 8, the double-layer rib full-enclosed structure 3 and the radial rib structure 4 can effectively improve the strength of the bumper assembly and ensure that it can replace the metal parts.

The bumper bracket of the present invention is injection-molded with long glass fiber reinforced polypropylene, and the length of the glass fiber is 5-7mm, and through the improved injection molding process, the length of the glass fiber in the product is guaranteed to be 3-5mm, and the length of the glass fiber is 3-5mm. And the high crystalline polypropylene resin makes the high temperature fatigue strength of the material at 120°C twice that of ordinary glass fiber reinforced polypropylene. The produced bumper bracket has excellent creep resistance and low shrinkage, and the dimensional stability of the parts Good, high installation accuracy, light weight, the bumper bracket is about 40% lighter than the metal bracket, and through one-piece injection molding, the work efficiency is greatly improved.

The technical means disclosed in the solutions of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
