Description

Technical Field

[0001] This application relates to the technical field of golf cart frames, and more particularly to a modular frame assembly. Background Technology

[0002] In the field of vehicle manufacturing, the chassis, as the core component that bears the entire vehicle structure, directly determines the assembly quality and reliability of the vehicle through the positional accuracy of its connection points (such as suspension mounting holes, powertrain mounting points, and body joint surfaces). Currently, the mainstream manufacturing process employs steel pipe welding forming technology.

[0003] For example, the commonly seen announcement number CN208021553U discloses an instrument panel tube beam assembly for automobiles, which belongs to the field of automotive parts technology. Its purpose is to provide a tube beam assembly with a stable effect. Its technical solution includes: a main tube beam, a fixing plate disposed in the middle of the main tube beam, the fixing plate including a crossbeam and connecting pieces disposed at both ends of the crossbeam, the other end of the connecting piece being fixedly connected to the main tube beam, a U-shaped fixing plate disposed at the lower end of the crossbeam, the U-shaped fixing plate having a hollow structure in the middle, and a connecting piece disposed in the middle of the crossbeam; a pair of fixing pieces are also disposed at the connection between the main tube beam and the fixing plate, and a second connecting plate and a third connecting plate are also disposed at both ends of the main tube beam.

[0004] The pipe beams are fixed together by welding, which leads to uneven material expansion caused by localized high temperatures (usually above 1400℃) during the welding process, resulting in residual stress after cooling. Even with tooling and fixtures, it is still difficult to avoid the cumulative deformation of multiple welds, resulting in the three-dimensional coordinate offset of key connection points. This causes the mounting holes of fixing plates and connecting pieces on the pipe beams to shift, leading to excessively large or small clearances after the subsequent installation of the cover parts, resulting in abnormal noise. Utility Model Content

[0005] To address the aforementioned technical issues, this application provides a modular frame assembly that ensures structural strength while maintaining the precision of each mounting hole, thereby reducing the occurrence of abnormal noises and other issues.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A modular vehicle frame assembly includes a frame body, a front suspension assembly, a rear suspension assembly, a side skirt assembly, and an instrument panel assembly mounted on the frame body;

[0008] The dashboard assembly includes a top plate and a bottom plate. A connecting support plate is provided between the top plate and the bottom plate. The top end of the connecting support plate is connected to the top plate, and the bottom end of the connecting support plate is riveted to the main body of the vehicle frame. A transverse support rod is provided between the connecting support plates. The top end of the bottom plate is provided on the transverse support rod. The bottom end of the bottom plate is provided with a riveting part that connects to the side guard plate assembly. A support member is provided between the top plate and the main body of the vehicle frame.

[0009] To achieve the above technical solution, the entire dashboard assembly consists of a top plate and a bottom plate connected and fixed by a connecting support plate, eliminating the need for welding. This ensures the precision of each mounting hole on the top and bottom plates, thereby guaranteeing the accuracy of the fit after the subsequent cover parts are installed. Simultaneously, after the bottom end of the connecting support plate is fixed to the main body of the vehicle frame, the top plate is also fixed by the support component, and the bottom plate is fixed by riveting to ensure the stability of the bottom and top plates. This achieves both structural strength and the precision of each mounting hole, reducing the occurrence of abnormal noises and other issues later on.

[0010] As a preferred embodiment of this application, the support member includes a pair of vertical support rods, with an L-shaped fixing plate at the bottom of the vertical support rods. The top and side walls of the L-shaped fixing plate are riveted to the main body of the vehicle frame, and the top plate abuts against the top of the support rod.

[0011] To achieve the above technical solution, the top and side walls of the L-shaped fixing plate are riveted to the longitudinal support plate, thereby ensuring the reliability of the vertical support rod. The top plate abuts against the top of the support rod, thereby further supporting and fixing the top plate, thus ensuring the reliability of the top plate.

[0012] As a preferred embodiment of this application, a transverse connecting rod is further provided between the vertical support rods, and an auxiliary connecting member is provided between the transverse connecting rod and the front suspension assembly for connection.

[0013] The above technical solution is implemented to further ensure overall robustness and tightness.

[0014] As a preferred embodiment of this application, the frame body includes several longitudinal support plates and transverse support plates that are riveted and fixed together, wherein the two middle longitudinal support plates protrude longitudinally from the transverse support plates.

[0015] The above technical solution is achieved because the longitudinal support plate and the transverse support plate are riveted and fixed to each other, which can ensure that the main body of the frame will not deviate due to thermal stress caused by welding, etc., so as to ensure the dimensional accuracy of other assemblies when they are installed on the main body of the frame.

[0016] As a preferred embodiment of this application, the side guard assembly includes a side plate and a plurality of triangular connecting plates for connecting the side plate and the main body of the vehicle frame.

[0017] The above technical solution is implemented so that the side panels can protect the main body of the frame, and foot pedals and other devices can be installed on the outer shell of the side panels for subsequent use.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The entire dashboard assembly consists of a top plate and a bottom plate connected and fixed by a connecting support plate, eliminating the need for welding. This ensures the precision of the mounting holes on the top and bottom plates, thereby guaranteeing the accuracy of the fit after the subsequent cover parts are installed. Simultaneously, after the bottom end of the connecting support plate is fixed to the vehicle frame, the top plate is also secured by the support components, and the bottom plate is fixed by riveting, ensuring the stability of both the top and bottom plates. This achieves both structural strength and the precision of the mounting holes, reducing the likelihood of subsequent abnormal noises. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1 to 4 This application will be described in further detail.

[0027] This application discloses an assembled vehicle frame assembly. (Refer to...) Figure 1 A prefabricated vehicle frame assembly includes a frame body 1, a front suspension assembly 2, a rear suspension assembly 3, a side guard plate assembly 4, and an instrument panel assembly 5 mounted on the frame body 1.

[0028] As shown in the figure, the main frame 1 includes several longitudinal support plates 11 and transverse support plates 12 that are riveted together. The two middle longitudinal support plates 11 protrude longitudinally from the transverse support plates 12 to accommodate the instrument panel assembly 5 and the front suspension assembly 2. Because the longitudinal support plates and transverse support plates 12 are riveted together, the dimensions of the main frame 1 are prevented from deviating due to thermal stress generated by welding, ensuring dimensional accuracy when other assemblies are mounted on the main frame 1.

[0029] The side guard assembly 4 includes a side plate 41 and several triangular connecting plates 42 for connecting the side plate 41 and the frame body 1, so that the side plate 41 can protect the frame body 1. At the same time, foot pedals and other devices are installed on the upper shell of the side plate 41 for subsequent use.

[0030] The dashboard assembly 5 includes a top plate 51 and a bottom plate 52, with a connecting support plate 53 between them. The top end of the connecting support plate 53 is connected to the top plate 51, and the bottom end is riveted to the frame body 1, thus fixing the top plate 51 to the connecting support plate 53 after the bottom end of the connecting support plate 53 is fixed to the frame body 1. To ensure the sturdiness of the top plate 51, a support member 54 is provided between the top plate 51 and the frame body 1. The connecting support plate 53 is bent, and a snap-fit ​​groove is provided at the bend. A transverse support rod 55 is snapped and fixed between multiple snap-fit ​​grooves of the connecting support plates 53. The top end of the bottom plate 52 is set on the transverse support rod 55, and the bottom end of the bottom plate 52 is provided with a connecting plate that connects to the side guard plate assembly 4. The bottom plate 52 is also provided with a positioning part 522 that rests on the top end of the frame body 1 to ensure the stability of the bottom plate 52, while ensuring the accuracy of the structural dimensions without welding. C-shaped snap-fit ​​plates 56 are riveted to both ends of the base plate 52. The bottom end of the C-shaped snap-fit ​​plate 56 abuts against the side plate 41, and the top end abuts against the top plate 51, thereby allowing the top plate 51 to be positioned secondary by the C-shaped snap-fit ​​plate 56, thus ensuring the accuracy and reliability of the position of the top plate 51.

[0031] The support member 54 includes a pair of vertical support rods 541. An L-shaped fixing plate 542 is provided at the bottom of each vertical support rod 541. The top and side walls of the L-shaped fixing plate 542 are riveted to the longitudinal support plate 11, ensuring the reliability of the vertical support rods 541. The top plate 51 abuts against the top of the support rods, further supporting and fixing the top plate 51, thus ensuring its reliability. Furthermore, a transverse connecting rod 543 is provided between the vertical support rods 541. An auxiliary connecting member 544 is provided between the transverse connecting rod 543 and the front suspension assembly 2, further ensuring overall reliability and tightness.

[0032] The implementation principle of the prefabricated vehicle frame assembly in this application embodiment is as follows: The entire dashboard assembly 5 is composed of a top plate 51 and a bottom plate 52 connected and fixed by a connecting support plate 53 without welding, thereby ensuring the accuracy of each mounting hole on the top plate 51 and the bottom plate 52, and thus ensuring the accuracy of the fit after the subsequent installation of the cover parts. At the same time, after the bottom end of the connecting support plate 53 is fixed to the main body of the vehicle frame 1, the top plate 51 is also fixed by the support member 54, and the bottom plate 52 is fixed by the riveting part 521 to ensure the stability of the bottom plate 52 and the top plate 51, thereby ensuring the structural strength while ensuring the accuracy of each mounting hole, so as to reduce the occurrence of abnormal noises and other issues later.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
