Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] Embodiment 1:

[0025] A beam-column structure of a frame for resisting longitudinal torsion includes a frame. The frame includes a longitudinal beam 1 and a cross beam 2. Between the longitudinal beams 1, there is a beam-column 3. The beam-column 3 is a hollow tubular structure, and both ends of the beam-column 3 are provided with a connecting part 4 for connecting and fixing with the longitudinal beam 1. The connecting part 4 ensures the stability of the connection between the beam-column 3 and the longitudinal beam 1, so as to enhance the stability of the frame and improve the ability of the frame beam-column structure to resist longitudinal torsion.

[0026] The connecting part 4 includes a connecting piece 401, a connecting foot 402 and a reinforcing plate 403. The connecting piece 401 is fixedly installed at both ends of the beam-column 3, and connecting feet 402 are provided at the top and bottom of the connecting piece 401. The connecting feet 402 are connected and fixed to the longitudinal beam 1 by bolts. Two reinforcing plates 403 are fixedly installed in the hollow cavity of the longitudinal beam 1. The two reinforcing plates 403 are used to enhance the ability of the beam-column 3 to resist longitudinal torsion.

[0027] The connecting part 4 further includes a positioning groove 404 arranged between the two reinforcing plates 403. The positioning groove 404 is adapted to the connecting piece 401 and the connecting foot 402, and the two sides of the positioning groove 404 are in contact with the connecting piece 401 and the connecting foot 402, so as to realize the quick positioning and installation between the connecting part 4 and the longitudinal beam 1.

[0028] The first mounting holes 5 are evenly formed in the connecting feet 402, and the first mounting holes 5 are connected and fixed to the second mounting holes 6 formed in the longitudinal beam 1 through bolts.

[0029] In this embodiment, the connecting parts 4 are arranged at both ends of the beam column 3, and the connection and fixation with the longitudinal beam 1 are realized through the connecting parts 4 to ensure the stability of the connection and improve the longitudinal force bearing of the beam column. Two reinforcing plates 403 are arranged in the hollow cavity at the installation position of the beam column 3 on the longitudinal beam 1. A positioning groove 404 is arranged between the two reinforcing plates 403, and the positioning groove 404 is adapted to the connecting part 4. During the installation process, the reinforcing plates 403 on both sides of the connecting part 4 are in contact with both sides of the connecting part 4, and the longitudinal force bearing of the beam column 3 is strengthened through the reinforcing plates 403, avoiding the longitudinal force bearing directly by the bolts and strengthening the stability of the structure, thereby enhancing the safety and stability of the vehicle.

[0030] An installation opening 7 is formed above the positioning groove 404, and the installation opening 7 facilitates the installation of the connecting part 4.

[0031] The installation opening 7 is adapted to a sealing plate 8, and the sealing plate 8 is fixedly installed on the upper connecting foot 402 and is used for closing the installation opening 7 during the installation of the beam column 3 to ensure the integrity of the vehicle frame.

[0032] By forming the installation opening 7 on the longitudinal beam 1 above the positioning groove 404, the disassembly and assembly of the beam column 3 are facilitated. With the sealing plate 8 fixedly installed above the connecting foot 402, when the beam column 3 and the longitudinal beam 1 are connected and fixed, the sealing plate 8 is accurately stuck in the installation opening 7 to ensure the integrity of the structure.

[0033] A number of third mounting holes 9 are arranged on the beam column 3 along the extending direction of the beam column 3. And on the inner wall of the hollow beam column 3 at the position corresponding to the third mounting holes 9, there are protrusions 10 protruding towards the axis direction of the beam column 3. The protrusions 10 extend along the axis direction of the beam column 3. The wall thickness of the beam column 3 at the position of the protrusions 10 is greater than the wall thickness of other positions of the beam column 3. The wall thickness of the beam column 3 at the position corresponding to the third mounting holes 9 is designed to be thickened, so that the installation points for installing valve-type and sensor-type parts on the vehicle are more stable. While meeting the principle of the strength requirement of the installation base surface, the wall thickness of the beam column 3 in other circumferential directions is not thickened, realizing the lightweight requirement of the vehicle frame structure. The protrusions 10 are arranged on the inner wall of the beam column 3, that is, the surface of the beam column 3 is still a smooth and flat square columnar structure, providing a flat installation base surface for installing valve-type and sensor-type parts. The protrusions 10 are arranged in the hollow internal space of the beam column 3 so that the overall volume of the beam column 3 is small, ensuring the strength of the vehicle frame structure while meeting the lightweight requirement.

[0034] Working principle: First, the installation and fixation between the longitudinal beam 1 and the beam-column 3 are achieved through the connecting part 4 fixedly connected therebetween, effectively improving the connection strength between the vehicle frame and the beam-column 3, strengthening the beam-column 3's resistance to longitudinal torsion, and dispersing the force through reasonable design so that the force is distributed through more structural components, avoiding concentration on the bolts, ensuring the safety and reliability during the actual use of the structure, enhancing the overall structural safety. During the installation of the beam-column 3, the connecting parts 4 at both ends are directly slid downward corresponding to the installation openings 7 and inserted into the positioning grooves 404, so that both sides of the connecting piece 401 and the connecting feet 402 are in contact with the reinforcing plates 403 on both sides, and the sealing plate 8 is directly stuck in the installation opening 7, enabling accurate positioning between the first installation hole 5 and the second installation hole 6. The connection and fixation between the connecting feet 402 and the longitudinal beam 1 are achieved by using bolts. When the beam-column 3 bears longitudinal force, the reinforcing plates 403 and the bolts jointly bear the force, avoiding the force transmission being directly borne by a single bolt. The design of the reinforcing plates 403 is used to disperse the force, ensuring the safety and reliability of the structure during actual use and improving the connection strength between the vehicle frame and the beam-column 3.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
