Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a front-end accessory for a light truck frame. Background Technology

[0002] Currently, most mainstream light truck brands on the market adopt a sunken structure for the front section of their chassis. The advantage of this structure is that it allows the front of the chassis to sink, which significantly reduces the height of the front suspension mounting plane of the cab, thereby greatly reducing the height of the cab from the ground, lowering the center of gravity of the vehicle, and increasing the vehicle's driving stability.

[0003] However, the current common method for lowering the frame is to use a mold to press the front end of the frame longitudinal beams to lower them. However, this installation method has poor versatility and cannot adapt to the needs of different specifications of longitudinal beams. As the specifications of frame longitudinal beams in the market continue to change, the cost of mold pressing for frame production will also increase significantly. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a front-end accessory for a light truck frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A light truck frame front-end accessory includes two frame longitudinal beams and two front connecting beams. The two front connecting beams are detachably connected to the front ends of the two frame longitudinal beams respectively. The two front connecting beams are arranged in a mirror symmetrical manner. A crossbeam is detachably connected between the two front connecting beams, and there is a height difference between the two ends of the crossbeam.

[0007] Preferably, the crossbeam is configured as a frame structure, and a closed box-shaped structure is formed between the crossbeam and the two front connecting beams.

[0008] Preferably, at least two crossbeams are provided, and the crossbeams are distributed in the extension direction of the preceding beam.

[0009] Preferably, the front connecting beam has a vertical part and a flat part, with the flat part located at the top of the vertical part, and the flat part is perpendicular to the vertical part, with a height difference between the two ends of the flat part.

[0010] Preferably, the planar portion is provided with a horizontal portion one, a connecting portion and a horizontal portion two, which are arranged sequentially in a direction away from the longitudinal beam of the frame. The horizontal portion one and the horizontal portion two are set as parallel horizontal plane structures, and the connecting portion is inclined downward from the horizontal portion one towards the horizontal portion two.

[0011] Preferably, the connecting part is configured as an arc-shaped structure, and the connection positions of the connecting part and the horizontal part one, as well as the connection positions of the connecting part and the horizontal part two, are tangent to each other.

[0012] Preferably, the front connecting beam is manufactured using a stamping process, meaning that the vertical section, horizontal section one, connecting section, and horizontal section two are integrally formed.

[0013] Preferably, the outer wall of the front connecting beam has multiple mounting holes, and the specifications of the multiple mounting holes are different.

[0014] Preferably, the width of the second horizontal portion is greater than the width of the first horizontal portion.

[0015] Preferably, the two front connecting beams are respectively configured as a left front connecting beam and a right front connecting beam, and the left front connecting beam and the right front connecting beam are mirror-symmetrically arranged, with the top outer walls of the planar portion of the left front connecting beam and the right front connecting beam flush.

[0016] Compared with the prior art, the present invention provides a front-end accessory for a light truck frame, which has the following advantages:

[0017] By connecting the front-end attachment to the longitudinal frame, the front end of the straight longitudinal beam can be lowered. This eliminates the need for developing a forming mold for the longitudinal beam, significantly reducing production costs and ensuring better machining accuracy. Frame assembly components such as leaf spring supports can also achieve better assembly accuracy, improving production efficiency and reducing the number of assembly and adjustment operations. For frames with different web heights, only the hole positions need to be adjusted to ensure that the positioning of key hard points such as the cab and steering gear remains unchanged, reducing the number of product varieties, increasing the degree of commonality among series models, and lowering production costs. This application features a reasonable design, simple structure, low cost, simple process, convenient use, easy operation, and effective cost savings. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figure 1-4 A front-end accessory for a light truck frame includes two longitudinal beams 1 fixedly mounted to the vehicle body, and two front connecting beams 3. The two front connecting beams 3 are detachably connected to the front ends of the two longitudinal beams 1, respectively. The two front connecting beams 3 are arranged in a mirror symmetrical manner. A crossbeam 2 is detachably connected between the two front connecting beams 3. There is a height difference between the two ends of the crossbeam 2. It should be noted that the front connecting beams 3 and the longitudinal beams 1, as well as the front connecting beams and the crossbeam 2, are installed in corresponding positions by fasteners such as rivets or bolts. The detachable design of the front connecting beams 3 improves the universality of connection and installation, making it suitable for longitudinal beams of different specifications without the need to design separate left and right parts, saving the development cost of molding dies, and facilitating disassembly, assembly, replacement, and maintenance.

[0025] In this invention, the crossbeam 2 is configured as a frame structure, and the crossbeam 2 and the two front connecting beams 3 form a closed box structure; the closed box structure can effectively improve the overall rigidity and structural strength of the front end of the frame.

[0026] In this utility model, at least two crossbeams 2 are provided. The crossbeams 2 are distributed in the extension direction of the front connecting beam 3. It should be noted that: if only two crossbeams 2 are provided, the two crossbeams 2 are distributed at both ends of the front connecting beam 3; if more than two crossbeams 2 are provided, the crossbeams 2 located at both ends are distributed at both ends of the front connecting beam 3, while the other crossbeams 2 are distributed between the two ends; the distribution of multiple crossbeams can disperse the front load and improve the overall load-bearing capacity.

[0027] In this utility model, the front connecting beam 3 is provided with a vertical part 32 and a flat part 31. The flat part 31 is located at the top of the vertical part 32 and is perpendicular to the vertical part 32. There is a height difference between the two ends of the flat part 31. It should be noted that the vertical part 32 is in contact with the inner wall of the frame longitudinal beam 1, and the flat part 31 extends towards the direction of the crossbeam 2. The flat part 31 is provided with a horizontal part 1 311, a connecting part 312, and a horizontal part 2 313, which are distributed sequentially in the direction away from the frame longitudinal beam 1. The horizontal section 311 and the horizontal section 313 are configured as parallel horizontal plane structures. The connecting section 312 is inclined downward from the horizontal section 311 towards the horizontal section 313. The horizontal section 311 and the horizontal section 313 are parallel horizontal planes, which can provide a stable installation reference for different components (such as cab suspension and crossbeam connecting seat) to ensure installation accuracy. The inclined connecting section 312 realizes a smooth height transition from the horizontal section 311 to the horizontal section 313, avoids stress concentration caused by sudden height changes, and improves the structural reliability of the front connecting beam.

[0028] In this utility model, the connecting part 312 is configured as an arc-shaped structure, and the connection positions of the connecting part 312 and the horizontal part 1 311, as well as the connection positions of the connecting part 312 and the horizontal part 2 313, are tangent to each other, so that the connecting part 312 smoothly transitions with the horizontal part 1 311 and the horizontal part 2 313.

[0029] In this utility model, the front connecting beam 3 is made by stamping process, that is, the vertical part 32, the horizontal part 1 311, the connecting part 312 and the horizontal part 2 313 are integrally formed structure, thereby improving the overall strength and load-bearing capacity of the front connecting beam 3.

[0030] In this utility model, the outer wall of the front connecting beam 3 is provided with multiple mounting holes, and the specifications of the multiple mounting holes are different; different specifications of mounting holes can be adapted to the installation needs of various parts on the vehicle (such as cab suspension, steering gear, wiring harness fixing bracket, etc.), without the need to design separate installation accessories for different parts, thus improving versatility.

[0031] In this invention, the width of the second horizontal part 313 is greater than the width of the first horizontal part 311, thereby achieving a lightweight structure while ensuring load-bearing capacity.

[0032] In this invention, the two front connecting beams 3 are respectively set as the left front connecting beam and the right front connecting beam. The left front connecting beam and the right front connecting beam are mirror-symmetrically arranged, and the top outer walls of the flat parts of the left front connecting beam and the right front connecting beam are flush. This is a key factor in ensuring the balance and stability of the front structure of the frame. Only by ensuring that the corresponding planes are at the same height can the frame maintain balance when subjected to force, and avoid uneven force due to inconsistent heights, which would affect the frame performance and vehicle driving safety.

[0033] During installation, the left and right front connecting beams are first accurately placed inside the longitudinal beams, and then the crossbeam is placed inside the front connecting beams. Next, the left and right front connecting beams are firmly connected to the frame longitudinal beams by riveting or bolting. After the left and right front connecting beams are connected by the crossbeam, they form a closed box-shaped structure. This structure can significantly increase the strength of the frame, allowing it to maintain a stable structural shape when subjected to various loads during vehicle operation and the impact of complex road conditions, ensuring the safe operation of the vehicle. At the same time, the different sizes of mounting holes on the left and right front connecting beams can provide accurate mounting positions for different parts on the vehicle. The parts are installed in the corresponding positions by fasteners such as rivets or bolts, completing the vehicle assembly.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
