Heavy truck front bumper using plastic to replace steel

Technical Field

The utility model belongs to the technical field of the automotive technology and specifically relates to a with moulding replace steel heavily block front bumper.

Background

In the prior art, a heavy truck front bumper is formed by combining an outer plate, a welding bracket and a headlamp bracket, wherein the outer plate is made of PP (polypropylene) or EPDM (ethylene propylene diene monomer) materials and weighs 4.4 kg; the welding bracket is made of steel and weighs 16 kg; the headlamp brackets are made of PP (polypropylene) or GF30 (containing 30% of glass fiber), and each headlamp bracket weighs 1 kg; the total mass of the front bumper of the heavy truck is 21.4 kg.

The heavy truck front bumper has the following problems:

1. the whole weight is large, and the vehicle weight is increased;

2. the welding bracket is made of metal, and paint is easy to rust after the welding bracket is collided;

3. the mounting point of the car body is fixed by a welding nut, the welding is easy to deform, and the size during loading cannot be ensured;

4. at least two suppliers need to be contacted, and the batch feeding of the outer plate and the welding bracket is complicated;

5. feeding the outer plate into a spraying line after feeding, independently coating and baking the outer plate, and easily deforming at high temperature; because the welding bracket has surge, the welding bracket can not be baked at high temperature, the welding bracket can not be used as the bracket of the outer plate to enter a spraying line along with the outer plate, and the welding bracket is fed and then assembled on the line;

6. if the residual pickling liquid of the surge of the welding bracket is not cleaned, the paint can be polluted.

Therefore, there is a need for an improved heavy truck front bumper in the prior art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a with moulding the heavy truck front bumper of replacing the steel, can reduce its weight when guaranteeing the front bumper rigidity.

In order to realize the technical effects, the utility model adopts the technical scheme that: the utility model provides a heavily block front bumper with mould to replace steel, includes the planking, the both sides of planking are provided with the headlight vacancy, the middle part of planking is provided with outer vent, the top of outer vent is provided with license plate installation position, the below of outer vent is provided with the footboard outward to the evagination, still include with planking matched with inner panel, the inner panel with planking fixed connection. Through such design, original welding stent and headlight support are replaced to the inner panel, and the structure is reduced to 2 parts by former 4 parts, has reduced and has assembled the link.

The preferable technical scheme is that the inner plate is provided with an inner vent, and the inner vent corresponds to the outer vent. By such a design, the ventilation and heat radiation performance of the front bumper can be ensured

The inner plate is provided with a headlamp mounting position, the headlamp mounting position is provided with a plurality of mounting points, and the headlamp mounting position corresponds to the headlamp vacancy. By means of such a design, the heavy truck headlight can be mounted on the inner panel by means of such a design.

The preferable technical scheme is that the inner plate is provided with pedal protrusions, the pedal is provided with grooves, and the pedal protrusions are located in the grooves. Through such design, the pedal protrusion penetrates through the groove of the pedal to be integrated with the pedal, so that the strength of the pedal is enhanced.

The preferable technical scheme is that the outer plate is made of PP or EPDM materials and is molded integrally by injection. Through the design, the outer plate can ensure the aesthetic feeling of the appearance and the design of the designated shape.

The preferred technical scheme does, the inner panel is the SMC material and moulds plastics integrated into one piece. Through the design, the inner plate is arranged by plastic instead of steel, so that the weight of the front bumper is reduced, and the rigidity of the front bumper can be ensured.

The preferable technical scheme is that the inner plate is in snap connection or threaded connection with the outer plate. Through such a design, the fixed connection of the inner plate and the outer plate can be realized.

The utility model has the advantages and the beneficial effects that:

1. the original welding support and the headlamp support are replaced by the inner plate, the structure is reduced from 4 parts to 2 parts, and the assembling links are reduced;

2. the inner plate is made of SMC (sheet molding compound) instead of steel, the strength is high, the weight is light and is only 12.2kg, and the total mass of the outer plate and the inner plate is 16.2kg, so that compared with the prior art, the total mass of the front bumper is reduced by 24.3%;

3. the inner plate can be baked at high temperature and can be used as a bracket of the outer plate to enter a spraying line, so that the deformation of the outer plate is effectively avoided;

4. suppliers are reduced, the outer plate and the inner plate can be provided by the same supplier, and the transportation cost is reduced;

5. the inner plate is made of SMC material, is corrosion resistant and does not need surge coating;

6. all mounting points may be pre-buried in a high strength inner panel.
