Description

A low-roof truck bumper combination bracket

Technical field

The utility model relates to a low-roof truck bumper combination bracket, which belongs to the technical field of truck parts.

Background technique

As a connector between the bumper and the frame beam, the bumper bracket structure must ensure the structural strength of the vehicle under different working conditions. It should be as simple in structure as possible, easy to process, light in weight and low in cost. According to light truck market research feedback, some users require vehicles with a vehicle height lower than 2100mm to facilitate transportation into old garages and basements. Most common bumper brackets in the light truck market match the height of the frame and bumper, and the collision stress surface is near the center of the front of the crossbeam. The bracket is usually fixed in front of the crossbeam. In order to meet the vehicle height reduction requirements, while reducing the height of the cab and bumper from the ground, there will be a significant height difference between the bumper and the frame cross member mounting surface. The lowering of the bumper will cause the stress center to move downward after a collision, and may appear below the bottom surface of the cross beam, resulting in the fact that it cannot meet the strength requirements of the bumper support only if it is fixed in front of the cross beam. And enough space must be reserved in front of the bumper and frame beam to ensure that the cab can be flipped. Therefore, the existing bumper bracket structure cannot be used.

Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in Figures 1 to 5, the utility model provides a low-roof truck bumper combination bracket, which includes a bumper 55, a bumper bracket 44 and a frame beam 3. The bumper bracket 44 includes a bracket. 4 and bracket two 5. Bracket one 4 is an Ω-shaped structure, and bracket two 5 is a C-shaped bending structure. The sides of bracket one 4 and bracket two 5 are welded and connected internally and externally to form a rear mounting surface, a top mounting surface and two The bumper bracket 44 on the front mounting surface is integrated to enhance the overall structural strength; the top mounting surface is installed with the lower wing surface of the frame beam 3, the two front mounting surfaces are connected with the frame beam 3, and the rear mounting surface is connected with the bumper 55 Connection; the bumper bracket 44 has the function of connecting the bumper 55 to the frame.

The bracket one 4 includes two front mounting surfaces, one rear mounting surface and two side parts. The rear mounting surface is provided with a first mounting hole 101, and the front mounting surface is provided with a second mounting hole 102. The second mounting hole 102 The first mounting hole 101 is offset from the first mounting hole 101, and a welding nut 11 is provided inside the first mounting hole 101; the bracket 4 is installed with the bumper 55 through the first mounting hole 101 using bolts 3 10 and the welding nut 11, and is installed through the second mounting hole 101.
