Description

Technical Field

[0001] This utility model relates to the field of vehicle frame accessories technology, specifically an adjustable vehicle frame accessory. Background Technology

[0002] The car frame, commonly known as the chassis, is the assembly base of a car. Most of the car's components and assemblies, such as the engine, transmission, driveshaft, front and rear axles, and body, are mounted on the frame. The frame primarily supports and connects the various car parts and bears various loads from inside and outside the vehicle. The frame is a crucial foundation in automobile production, especially for large and medium-sized buses where quality and safety requirements are extremely high. The frame production process involves fixing crossbeams and longitudinal beams together to form a complete frame. However, existing crossbeams are generally fixed with rivets, resulting in a constant overall frame width when the crossbeams and longitudinal beams are riveted. When the frame width needs adjustment, the crossbeams must be replaced, which is not only troublesome but also requires reprocessing. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an adjustable frame component. This solves the problem that the existing crossbeam components mentioned in the background technology are generally fixed by riveting, which results in a constant overall frame width when the crossbeam components are riveted to the longitudinal beam components. When the frame width needs to be adjusted, the crossbeam components need to be replaced, which is not only troublesome but also requires reprocessing of the crossbeam components.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable frame accessory, including a crossbeam structure, wherein connecting structures are installed on both sides of the crossbeam structure;

[0005] The beam structure includes a beam body with weight-reducing holes on its surface, and a through slot hole through the surface of the beam body to facilitate the through adjustment and fixing of connecting structural components.

[0006] The connecting structure includes a connecting lug with a weight-reducing hole on its surface, and a through hole for easy connection of expansion bolts on one side of the connecting lug. The connecting lug is installed and connected to the crossbeam body through the through slot and through hole block of the expansion bolt.

[0007] By adopting the above technical solution, the expansion bolts are used to achieve adjustment and fixation.

[0008] Preferably, the through slots are provided in 4 groups, and each group of through slots has 3 slots.

[0009] By adopting the above technical solution, the through-holes are used to achieve directional sliding adjustment.

[0010] Preferably, there are four connecting ears, and the overall shape of the connecting ears is an "L" structure.

[0011] By adopting the above technical solution, the connecting ears are designed to facilitate opening and fitting during installation.

[0012] Preferably, the through holes are equidistantly opened on the surface of the connecting ear, and the through holes and the through slot holes are aligned.

[0013] By adopting the above technical solution, a through-hole is created to achieve a through-connection.

[0014] Preferably, the number of through-hole blocks is the same as the number of expansion bolts, and the through-hole blocks are made of metal.

[0015] By adopting the above technical solution, the through-hole block achieves a through-fitting and fastening connection.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this adjustable frame accessory,

[0017] (1) This case solves the problem that existing crossbeam accessories are generally fixed by rivets, which results in a constant overall frame width when the crossbeam accessories and longitudinal beam accessories are fixed by rivets. When the frame width needs to be adjusted, the crossbeam accessories need to be replaced, which is not only troublesome but also requires reprocessing of the crossbeam accessories. When it is necessary to adjust the lateral distance between the connecting structures, the connecting structure can be manually pushed to slide relative to the through slot and the crossbeam body. The distance between the connecting structures can be adjusted synchronously or individually by changing the distance between the connecting structures. By changing the distance between the connecting structures, the length of the overall crossbeam accessories can be changed, thereby changing the overall width of the frame.

[0018] (2) By setting the connecting structure, the problem of the connecting ear and the crossbeam body being unable to be initially and quickly connected and fixed is solved. After the connecting ear is adjusted to the required distance length, the operator manually inserts the expansion bolt through the connecting ear, the crossbeam body and the through hole block and then tightens the expansion bolt to initially fix the connecting ear and the crossbeam body. The initial fixing of the two not only facilitates the subsequent hammering adjustment of the two but also initially fixes the two to avoid displacement and loosening. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an adjustable frame accessory, such as... Figure 1 and Figure 2 As shown, the structure includes a crossbeam structure 1, which includes a crossbeam body 101 with weight-reducing holes 102 on its surface. The surface of the crossbeam body 101 is provided with through slots 103 for easy connection and adjustment of the components of the connecting structure 2. There are 4 sets of through slots 103, and each set of through slots 103 has 3 slots. When the structure has 4 sets of 12 slots, it not only reflects the continuity of the structure, but also the guiding and sliding adjustment of the structure. Furthermore, when the structure has 4 sets of 12 slots, it reflects the aesthetics and the practicality of the equidistant arrangement.

[0027] like Figure 3 , Figure 4 and Figure 5As shown, connecting structures 2 are installed on both sides of the crossbeam structure 1. Each connecting structure 2 includes four connecting ears 201, each with a weight-reducing hole 102 on its surface. The overall shape of the connecting ears 201 is "L". The presence of four connecting ears ensures equidistant fitting and fixation, as well as individual or synchronous drive adjustment. Furthermore, the four connecting ears ensure fixed connection between the components and the crossbeam 101 and the longitudinal beam. The "L" shape of the connecting ears 201 effectively facilitates connection and installation on both sides. One side of each connecting ear 201 has a through hole 202 for easy connection of an expansion bolt 203. These through holes 202 are equidistantly located on the surface of the connecting ear 201 and aligned with the through slot 103. This equidistant arrangement of the through holes on the surface of the connecting ear 201 further enhances its structural integrity. This demonstrates both the aesthetic appeal and practicality of the equidistantly spaced structure. Furthermore, by aligning the structure with the through-slot 103, it avoids the situation where misalignment between the structure and the through-slot 103 would prevent quick installation and connection between the connecting ear 201 and the crossbeam 101. Simultaneously, the connecting ear 201 is connected to the crossbeam 101 via expansion bolts 203 passing through the through-slot 103 and through-hole blocks 204. The number of through-hole blocks 204 is the same, and they are made of metal. The fact that the number of these components is the same as the number of expansion bolts 203 effectively expands and fixes the bolts. The metal material of the through-hole blocks 204 also facilitates welding the components to the crossbeam 101, increasing the fixing strength between the crossbeam 101 and the connecting ear 201.

[0028] In the above scheme, when it is necessary to adjust the lateral distance between the connecting ears 201, the connecting ears 201 can be manually pushed to slide relative to the through hole 103 and the crossbeam 101. The distance between the connecting ears 201 on one side can be adjusted simultaneously or individually. By changing the distance between the connecting ears 201, the length of the overall crossbeam component can be changed, thereby changing the overall width of the frame. After the connecting ears 201 are adjusted to the required distance, the operator manually inserts the expansion bolts 203 through the connecting ears 201, the crossbeam 101 and the through hole block 204 and tightens the expansion bolts 203 to initially fix the connecting ears 201 and the crossbeam 101.
