[0028] The cross beam assembly 100 includes two connecting members 10 and a supporting member 20. The connecting members 10 are located at both ends of the cross beam assembly 100 and are used to connect the longitudinal beams of the frame. The supporting member 20 is sandwiched between the two connecting members 10 to form an integral structure. The supporting member 20 adopts a tubular structure, and its cross section is a closed structure, which has good rigidity and load-bearing capacity, especially the torsional rigidity improvement effect is obvious.

[0029] Furthermore, the connector 10 can be made of high-grade material, and the wall thickness can be reduced while meeting the target requirements of the frame assembly strength and stiffness, and the structure can be optimized to make the force distribution of the connector 10 more uniform and reduce the weight of the part.

[0030] Reference Figure 1-2 As shown, the two connecting members 10 and the supporting member 20 are integrally formed. In the design of the frame structure, many connecting elements are often required, which leads to an increase in the number of parts, manufacturing cost and weight. The connecting member 10 and the supporting member 20 are arranged as an integrally formed structure, which can reduce the number of parts, not only reduce the manufacturing and installation steps, reduce the production cost, but also improve the overall rigidity and strength of the structure.

That is, the cross section of the support member 20 is not limited to one shape, and the rigidity, load-bearing capacity and torsion resistance of the frame assembly can be improved as long as it is a closed structure, such as a circle, a square and an ellipse.

[0033] Reference Figure 1-2 As shown, a plurality of mounting holes 21 are provided in the circumferential direction and / or the axial direction of the support member 20, and the mounting holes 21 are used to fix the wire harness. That is, the mounting holes 21 are reserved on the support member 20 to organize and arrange the wire harness, prevent the wire harness from swinging around inside the equipment or in the vehicle structure, thereby reducing the entanglement and confusion between the wire harnesses, and the mounting holes 21 replace the function of the wire harness fixing bracket, thereby reducing the number of parts and the cost of the whole vehicle.

That is, the connector 10 is fixedly connected to the frame longitudinal beam through the mounting flange 11, and is connected to the support member 20 through the mounting protrusion 12, which can enhance the stability of the frame assembly and improve the rigidity of the entire structure. An opening having the same shape as the support member 20 is formed at one end of the mounting protrusion 12 connected to the support member 20, and the support member 20 can be fixed at the opening of the connector 10 by welding.

[0035] Reference Figure 1-4 As shown, a plurality of first mounting portions 13 are provided on the mounting flange 11, and the plurality of first mounting portions 13 are provided at the edge of the mounting flange 11. A plurality of second mounting portions are provided on the frame longitudinal beam, and the plurality of first mounting portions 13 and the plurality of second mounting portions are fixedly connected.

[0036] Reference Figure 1-4As shown, a plurality of third mounting portions 14 are provided at the connection between the mounting flange 11 and the mounting protrusion 12, and a plurality of fourth mounting portions are provided on the frame longitudinal beam, and the plurality of third mounting portions 14 and the plurality of fourth mounting portions are fixedly connected.
