Description

A new type of lightweight overhead box for heavy trucks

technical field

The invention relates to a novel lightweight overhead box for heavy-duty trucks, which is used for heavy-duty tractors used for long-distance freight, and can realize functions such as storage, decoration, lighting, shading, and fixing functional components such as driving recorders.

Background technique

At present, the overhead boxes with similar structure and material technology on the market have the following disadvantages:

1. The strength of the overhead box assembly mainly depends on the self-strength of the overhead box body and the strength of the connecting bracket to bear the self-gravity and external load of the product assembly. In order to improve the strength of the overhead box body and bracket, the weight of the overhead box body will be caused And the weight of the connecting bracket is too large to realize the lightweight of the product assembly.

2. The fixed point of the original product assembly is arranged on the top of the front panel of the overhead box body, close to the hinge of the box door panel. Local force will cause deformation of this area, thus affecting the cooperation between the door panel and the overhead box body.

3. The fixed points of the original product are distributed in two areas, one is the position on the partition near the door panel in the middle of the elevated box body, and the other is the position in the front arc curtain guide rail groove, which is at the position of the box on both sides of the product Without fixed points, the load generated by the weight of the items in the box and the attached driving recorder and other functional parts will cause deformation on both sides of the elevated box body or abnormal friction caused by deformation with the body and interior. ring.

4. The assembly of the original product assembly on the vehicle body is relatively complicated. Since pre-positioning and pre-fixing cannot be realized, the assembly is difficult and labor-intensive.

5. The rigidity of the original product mainly depends on the overhead box body, and the rigidity of other parts is insufficient, which leads to the deformation of the entire product assembly easily under the action of gravity or rapid acceleration and deceleration.

Contents of the invention

The purpose of the present invention is to overcome the above disadvantages and provide a new type of lightweight overhead box for heavy trucks that can realize lightweight products, not easily damaged and deformed, with high connection strength and high assembly efficiency

The purpose of the present invention is achieved like this:

A new type of lightweight overhead box for heavy trucks, which includes a door panel, a top connecting bracket, a side connecting bracket, an upper partition, a storage board, a cowl, a lower partition and an elevated box body;

The shape and size of the product can be adjusted appropriately according to different body sizes. For models with components, it can especially show its own characteristics of high strength and light weight, and has the following advantages:

1. Several main components involved in the present invention have good strength and rigidity. For example, the elevated box body and dash board adopt glass fiber reinforced rigid polyurethane foaming process, the partition adopts glass fiber reinforced nylon injection molding process, and the storage board Glass fiber reinforced honeycomb sandwich material is used. In addition, on the premise of ensuring sufficient strength and rigidity of the product itself, the weight of the product is controlled as much as possible. Lightweight and high-strength composite materials and processes are adopted. In terms of structural assembly, through reasonable assembly The connection allows each component to play a role in the overall structural strength, improving the structural strength and rigidity of the assembly.

2. The present invention transmits the gravity of the elevated box assembly to other components through the upper and lower partitions. Compared with other traditional elevated boxes that arrange the fixing points close to the door panels, the external load will not cause the deformation of the elevated box body, and also There will be no problems in the assembly between the door panel and the elevated box body, and the problem of deformation of the door panel due to the influence of the elevated box body is solved by keeping the fixed point away from the area with movable opening and closing parts.

3. The present invention solves the problem of deformation and abnormal friction noise caused by the weight of the heavy objects in the box and the weight of the functional parts on both sides of the elevated box body on both sides of the elevated box body by adding a fixed point on both sides of the product. Improve the connection strength and connection reliability of the product;

4. In the present invention, a predetermined positioning surface and a fixed pin are designed on the lower partition. When assembling, the product can be easily placed on the front beam of the vehicle body cab through the positioning surface, and then the product is pushed forward to insert the fixed pin of the product In the fixing hole of the beam, it will be easier and more convenient to assemble the product after it has supported more than half of its weight than other products, which not only reduces the labor intensity of assembly, but also improves the product assembly. assembly efficiency;

5. Several main components involved in the present invention have certain strength and rigidity themselves. When these parts are assembled into a whole, the overall strength and rigidity are greatly improved compared with the original ones, so that they will not be exposed to external forces. deformed below.
