DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0030] At present, the common box-type frame crossbeams and tubular frame crossbeams are relatively regular in shape. Although they can meet the strength requirements, the regular crossbeams cannot meet the use requirements for the space divided within the chassis frame with certain special requirements. During the design of a certain type of off-road vehicle chassis, corner module devices are required, and large special equipment needs to be placed inside the frame. Due to the compact structure of the chassis and limited local space, it is required to ensure the strength of the frame crossbeams, the strength of the corner module interfaces, and the strength of the upper equipment interfaces while ensuring a reasonable layout, and a lightweight design is required, which puts higher requirements on the crossbeams. Taking into account the space limitations, lightweight and process requirements, the existing crossbeams cannot meet the requirements.

[0031] Based on this, an embodiment of the present disclosure provides a frame crossbeam, and the longitudinal beam connecting part of the present disclosure is tightly connected to the left and right longitudinal beams of the frame, thereby increasing the structural strength of the frame while balancing the overall force of the frame. Its connection method makes the connection between the crossbeam and the frame more flexible and convenient, and transmits the force of the installation equipment to the frame longitudinal beam through the first equipment installation and the second equipment installation part, and has good load-bearing capacity. At the same time, the accommodating space provides a large layout space for the upper equipment.

[0032] The frame crossbeam is described in detail below through a specific embodiment:

[0033] Reference Figures 1 to 5 As shown, in a first aspect of the present disclosure, a frame crossbeam is provided, including a crossbeam body, including a longitudinal beam connecting portion 1 and an equipment installation portion 2; the longitudinal beam connecting portion 1 is arranged as a U-shaped plate structure, and the two side surfaces of the longitudinal beam connecting portion 1 are respectively connected to the left and right longitudinal beams, and the recessed portion of the longitudinal beam connecting portion 1 forms an accommodating space 3 between the longitudinal beams; the equipment installation portion 2 is arranged on both sides of the longitudinal beam connecting portion 1, and the equipment installation portion 2 has a first equipment installation portion 23 and a second equipment installation 24, the first equipment installation portion 2 is far away from the accommodating space 3, and the second equipment installation portion 2 is close to the accommodating space 3.

[0034] The longitudinal beam connection part 1 disclosed in the present invention is tightly connected to the left and right longitudinal beams of the frame, which increases the structural strength of the frame while balancing the overall force of the frame. Its connection method makes the connection between the longitudinal beam connection part 1 and the frame more flexible and convenient, and transmits the force of the installation equipment to the longitudinal beam of the frame through the first equipment installation part 23 and the second equipment installation part 24, and has good load-bearing capacity. At the same time, the accommodating space provides a large layout space for the upper equipment.

[0035] Specifically, the longitudinal beam connecting portion 1 of the present disclosure is set as a U-shaped plate structure, which can be embedded between two longitudinal beams to form an accommodation space, so that the upper-mounted equipment installed on the second equipment mounting portion 23 can be better embedded between the longitudinal beams, while providing a better installation space for the upper-mounted equipment, it also increases the integration and connectivity between the upper-mounted equipment and the frame as a whole, so that the frame as a whole has better strength and load-bearing effect. Figure 1As shown, the longitudinal beam connection part 1 and the equipment installation part 2 of the present invention are in an up-down structure, that is, the two sides of the longitudinal beam connection part 1 are connected to the longitudinal beam, and the equipment installation part 2 can be arranged above the top of the longitudinal beam, so that the present invention can realize more connection surfaces with the longitudinal beam to increase the structural strength. The first equipment installation part 23 is arranged on the side away from the accommodating space 3 for installing the corner module device, and the second equipment installation part 24 is arranged on the side close to the accommodating space 3 for installing the upper equipment so that the upper equipment part can be embedded in the accommodating space. In some embodiments, the upper equipment is not embedded in the accommodating space 3. At this time, functional parts such as reinforcing structures and slideways can be arranged inside the accommodating space 3, and multiple frame crossbeams of the present invention can be arranged in the entire longitudinal beam extension direction. It should be noted that the accommodating spaces 3 of multiple frame crossbeams can be connected front and back when installing equipment, and the components or reinforcing structures thereon form a parallel through structure with the longitudinal beam, thereby further increasing the overall strength and torsion and bending resistance of the frame.

[0036] In some embodiments, the longitudinal beam connecting portion 1 and the equipment mounting portion 2 are integrally formed to form a "J"-shaped structure.

[0037] In this embodiment, the longitudinal beam connecting portion 1 and the equipment mounting portion 2 are integrally formed to form an "X"-shaped structure, thereby reducing the connection structure between the two to increase strength.

[0038] In some embodiments, the longitudinal beam connection portion 1 and the equipment installation portion 2 are configured as a box-type structure, and there is an installation space inside the longitudinal beam connection portion 1 and the equipment installation portion 2 .

[0039] In this embodiment, the longitudinal beam connection part 1 and the equipment installation part 2 are configured as a box-type structure, and there is an installation space inside the longitudinal beam connection part 1 and the equipment installation part 2. The installation space can better protect the circuits of the upper equipment and the corner module device. The layout of the circuits is a well-known technology in the field and will not be repeated here.

[0040] In some embodiments, a plurality of first wire passing holes 11 are disposed on the longitudinal beam connecting portion 1 , and the plurality of first wire passing holes 11 are spaced apart along the extending direction of the accommodating space 3 .

[0041] In this embodiment, if Figure 3 As shown, in order to better arrange the lines of the upper equipment and the corner module device, a plurality of first wire holes 11 are provided on the longitudinal beam connection part 1 of the present disclosure, and the plurality of first wire holes 11 are arranged at intervals along the extension direction of the accommodating space 3. The plurality of first wire holes 11 are arranged at intervals along the extension direction of the accommodating space 3, which can not only arrange the lines but also play the role of weight-reducing holes. Furthermore, an independent exclusive weight-reducing hole 14 can also be provided on the longitudinal beam connection part 1. The first wire holes 11 can reasonably arrange the vehicle wiring harness and avoid the wiring harness from crowding out the surrounding equipment arrangement space.

[0042] In some embodiments, the longitudinal beam connecting portion 1 includes a side panel 12 and a bottom panel 13, the side panels 12 are arranged on opposite sides of the bottom panel 13, and the side panels 12 are provided with first wire holes 11, the first wire holes 11 are arranged at intervals along the central axis of the side panels 12, and the bottom panel 13 is provided with drainage holes 131, which can effectively prevent water from accumulating inside the beam and causing corrosion.

[0043] In this embodiment, if Figure 4 As shown, the side plate 12 is used to connect with the longitudinal beam, and a plurality of bolt holes are provided thereon. The bolt connection method makes the connection between the cross beam and the frame more flexible and convenient. The plurality of bolt holes are not only used to connect with the longitudinal beam, but also can provide more expansion openings for the installation and fixation of other equipment.

[0044] In some embodiments, the first equipment mounting portion 2 is provided with a sleeve 21, and a pad 22 is provided inside the sleeve 21, and the pad 22 is used to install the corner module device. In this embodiment, the corner module is an assembly that integrates the drive, brake, suspension, and steering integrated modules, which can reduce a large number of mechanical transmission components and optimize the layout space of the whole vehicle. In order to better install the corner module device, the present disclosure provides a sleeve 21 and a pad 22 provided inside to provide the corner module device with an installation position that can be embedded in the frame crossbeam, so that the corner module device can be better integrated with the frame crossbeam and improve the frame strength. Specifically, the inner wall shape of the sleeve 21 can be adaptively set according to the specific appearance of the corner module device.

[0045] In some embodiments, a second wire passing hole 211 is disposed on the inner wall of the sleeve 21 , and the second wire passing hole 211 is connected to the first wire passing hole 11 .

[0046] In this embodiment, a second wire passing hole 211 is provided on the inner wall of the sleeve 21 so that the wiring of the corner module device can be better arranged inside the frame crossbeam without having to cross other first wire passing holes 11 from the outside.

[0047] In a second aspect of the present disclosure, a vehicle frame is provided, including the above-mentioned frame crossbeam. Specifically, the frame is a frame-type structure spanning the front and rear axles of the car, commonly known as a beam, and is the base of the car. It is generally composed of two longitudinal beams and several crossbeams, and is supported on the wheels via a suspension device, a front axle, and a rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, so that the assemblies maintain a relatively correct position, and withstand various loads inside and outside the car. The present disclosure is arranged between the two longitudinal beams to replace the crossbeam of the prior art. The technical effects that can be achieved are as described above and will not be repeated here.

[0048] The use scenario of the present invention is not limited to off-road vehicles, but can also be small cars, mini cars, compact cars, medium cars, CDV models, MPV models, SUVs and other models. Its design size can be adaptively selected according to the actual size of different models. The present invention is provided with a first equipment installation part 23 for the installation of the corner module on the left and right sides. The corner module device is connected by screw connection, and the structural installation flexibility is high. The longitudinal beam connection part 1 and the equipment installation part 2 are welded by plates. The left and right sides of the longitudinal beam connection part 1 are connected to the frame longitudinal beam by bolts, and a support bracket is provided on the outside of the frame longitudinal beam to strengthen the structural strength. While connecting the left and right longitudinal beams of the frame, a larger space is provided in the middle of the left and right longitudinal beams of the frame to meet the needs of the upper equipment. The second equipment installation part 24 is provided with a mounting hole for the upper equipment, and the upper equipment is installed on the second equipment installation part 24 by screw connection, which is convenient for installation and disassembly. The present invention connects the upper equipment, the corner module device and the left and right longitudinal beams of the frame, and the force given by the upper equipment and the corner module device is transmitted to the frame longitudinal beam through the corner module frame cross beam. This combined structure has better strength and anti-torsion and anti-bending performance. The structure disclosed in the present invention can adapt to the inclination angle of the frame longitudinal beam, facilitate the installation of the cross beam, reasonably arrange the vehicle wiring harness, and avoid the wiring harness from crowding out the surrounding equipment layout space.
