[0002] The vehicle frame mainly consists of the chassis frame and the roof frame. When connecting the chassis frame and the roof frame, the connecting beams on both sides of the roof frame are connected to the sides of the chassis frame using bolts and nuts, thereby achieving the connection between the chassis frame and the roof frame.

[0003] When connecting the connecting beams on both sides of the roof frame to the chassis frame using bolts and nuts, the connecting holes on the connecting beams need to be aligned with the connecting holes on both sides of the chassis frame. Therefore, the connecting beams need to be leveled. Currently, the roof frame is mainly connected by hoisting it. As a result, the roof frame is suspended during installation, requiring workers to make multiple adjustments to the roof frame to level the connecting beams. Therefore, there are some inconveniences when connecting the chassis frame and the roof frame.

[0004] Furthermore, when the vehicle is connected to the chassis frame only through the connecting structures on both sides of the roof frame, there are still certain limitations due to poor overall stability. Summary of the Invention

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figures 1 to 5 As shown, this utility model discloses a vehicle frame structure, including a roof frame assembly and a chassis frame assembly. The chassis frame assembly includes a bottom carrier 1, with a front longitudinal beam 2 and a rear longitudinal beam 3 respectively provided on the left and right sides of the bottom carrier 1. The front longitudinal beam 2 and the rear longitudinal beam 3 are used to connect the front anti-collision beam and the rear anti-collision beam, respectively. A side beam is provided between the front longitudinal beam 2 and the rear longitudinal beam 3. The roof frame assembly includes a top carrier 8, with a front connecting ear 9 and a rear support seat 10 respectively connected to the front and rear ends of the top carrier 8. Side connecting ears 11 are provided between the support seats 10. A crossbeam 200 is provided on the roof frame assembly. The side connecting ears 11 are fixed on the crossbeam 200. The side connecting ears 11 are located on the front and rear sides of the top carrier 8. There are multiple side connecting ears 11, which are spaced apart from each other. The front connecting ears 9, the side connecting ears 11, and the rear support seat 10 can be connected to the front longitudinal beam 2, the side beam, and the rear longitudinal beam 3 of the chassis frame assembly, respectively, thereby realizing multi-point connection and improving the stability of the connection between the roof frame assembly and the chassis frame assembly.

[0028] The bottom carrier 1 has connecting seats 4 on its front and rear sides, which are connected to the crossbeam 200. There are multiple connecting seats 4, which are spaced apart. Since the connecting seat 4 is composed of a connecting part 41 parallel to the surface of the bottom carrier 1 and a leveling part 42 perpendicular to the connecting part 41, when connecting the roof frame assembly and the chassis frame assembly, the connecting crossbeam 200 of the roof frame assembly only needs to be abutted against the leveling part 42 (top of the leveling part 42) to quickly level the roof frame assembly, thereby improving the convenience of connecting the chassis frame assembly and the roof frame assembly. It should be noted that after the crossbeam 200 is abutted against the leveling part 42, it is necessary to ensure that the mounting hole on the connecting crossbeam 200 is aligned with the first connecting hole 421 penetrating the leveling part 42. Then, the crossbeam 200 and the connecting seat 4 can be fixed by inserting the bolt into the mounting hole and the first connecting hole 421 and tightening the nut on the bolt.

[0029] In addition, in this embodiment, the connecting seat 4 can slide in the horizontal direction. Since the length of the crossbeam 200 of the roof frame assembly of different types of vehicles is different, in order to ensure that multiple connecting seats 4 can fully contact the crossbeam 200 of different types of roof frame assembly, the connecting seat 4 is pushed to move horizontally to adjust its installation position. This ensures that each connecting seat 4 can fully support the crossbeam 200 of different types of roof frame assembly, thereby adapting to the installation of roof frame assembly of different models under the same platform and expanding the scope of application.

[0030] Specifically, a slide rail 5 is fixed to the outside of the bottom carrier 1 by welding. The slide rail 5 is coupled with a slider 6, which can form a sliding fit with the slide rail 5. The connecting seat 4 is fixed to the slider 6. Thus, by sliding the slider 6 on the slide rail 5, the connecting seat 4 can be driven to slide, thereby adjusting the installation position of the connecting seat 4.

[0031] In addition, to prevent accidental movement after the connection slides to the appropriate position, a first through hole 51 is provided on the slide rail 5. There are multiple first through holes 51, which are spaced apart from each other. A second through hole is provided on the bottom carrier 1, which is opposite to the first through hole 51. A second through hole 411 is provided on the connecting part 41. In this way, after the connecting seat 4 slides to the appropriate position by the slider 6, the bolt is inserted into the second through hole 411, the first through hole 51 and the second through hole, and then the nut is tightened on the bolt. This can fix the slider 6 and the slide rail 5, thereby preventing accidental movement of the connecting seat 4 and ensuring the stability of the connection between the roof frame assembly and the chassis frame assembly.

[0032] like Figure 6 As shown, one end of the front connecting ear 9 is fixed to the top carrier 8 by welding, and the other end extends toward the front longitudinal beam 2 of the chassis frame assembly and serves as a connecting end. The connecting end has a through front connecting hole 91, which can be matched with the corresponding connecting hole of the front longitudinal beam 2 of the chassis frame assembly, so that it can be fixed by means of rivets or bolts. The rear support 10 mainly includes a base rod 101. One end of the base rod 101 is fixed to the top carrier 8 by welding, and the other end has a mounting groove. The mounting groove has a support rod 102 that matches the mounting groove, so that the support rod 102 can slide in the mounting groove. Thus, when the rear support 10 is connected to the rear longitudinal beam 3 of the chassis frame assembly, the overall length of the rear support 10 can be adjusted by sliding the support rod 102, so as to adapt to the spacing between different roof frame assemblies and chassis frame assemblies, so as to facilitate the connection between the rear support 10 and the rear longitudinal beam 3 of the chassis frame assembly.

[0033] In addition, a support leg 12 is fixed at the end of the support rod 102 away from the base rod 101 (the extended end). The bottom of the support leg 12 is a planar structure parallel to the surface of the connection between the support leg 12 and the rear longitudinal beam 3 of the chassis frame assembly. This facilitates full contact between the support leg 12 and the rear longitudinal beam 3 of the chassis frame assembly, thereby improving the stability of the rear support seat 10 when it is supported on the rear longitudinal beam 3 of the chassis frame assembly. After the support leg 12 abuts against the rear longitudinal beam 3 of the chassis frame assembly, it can be fixed by means of, for example, rivets or bolts after aligning the rear connecting hole 121 through the support leg 12 with the corresponding connecting hole on the rear longitudinal beam 3 of the chassis frame assembly.

[0034] like Figure 8 As shown, a plurality of welding holes 101a are provided on the base rod 101, and are spaced apart from each other along the extension direction of the base rod 101. After the support rod 102 is slid to a suitable position, the support rod 102 needs to be fixed. The fixing is generally done by welding. Therefore, the welding holes 101a can expose the welding joint of the support rod 102, so that the welding gun can be easily inserted into the base rod 101 to weld the support rod 102 to the base rod 101, thereby improving the convenience of welding.

[0035] like Figure 6 and Figure 7 As shown, multiple side connecting ears 11 are spaced apart from each other, providing multiple connection points and thus improving the stability of connecting the side connecting ears 11 to the chassis frame side beam. Each side connecting ear 11 has an outwardly bent coupling portion 111, which contacts the outer side of the chassis frame assembly side beam. When connecting the side connecting ears 11 to the chassis frame assembly side beam, the bent coupling portion 111 wraps around the outer side of the chassis frame side beam. By aligning the side connecting hole 111a through the coupling portion 111 with the corresponding connecting hole on the outer side of the chassis frame assembly side beam, it can be fixed by rivets or bolts. Furthermore, a support parallel to the bottom of the chassis frame assembly side beam is provided below the coupling portion 111. The support portion 112 facilitates full contact between the side connecting ear 11 and the bottom of the side beam of the chassis frame assembly. After aligning the side bottom connecting hole 112a through the support portion 112 with the corresponding connecting hole at the bottom of the side beam of the chassis frame assembly, it can be fixed by rivets or bolts. Thus, the side connecting hole 111a and the side bottom connecting hole 112a provide multiple connection points between the side connecting ear 11 and the side beam of the chassis frame assembly, thereby improving the stability of the connection between the side connecting ear 11 and the chassis frame.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
