Description

Technical Field

[0001] The invention belongs to the technical field related to vehicle body frames, and in particular relates to a structure in which a wheel and a vehicle body frame are separated. Background Art

[0002] With the rapid development of new energy vehicles, the separation structure of wheels and body frames has gradually become a design concept for automobiles, which is usually used to improve the flexibility, maintainability and safety of vehicles. This construction method separates the wheel system from the body frame so that the two can work independently. When the wheels need to be replaced or repaired, the separation structure can simplify the maintenance process and reduce interference with the body frame. At the same time, the application of lightweight materials for automobile body frames is becoming more and more extensive. Among them, aluminum alloy materials have obvious advantages in lightweight. Therefore, parts made of aluminum alloy materials have been widely used in new energy vehicle models. Most of the parts on the main body frame are made of aluminum alloy materials.

[0003] However, the aluminum alloy frames of existing automobiles are mainly connected to each other by spot welding and burning welding. During the connection process, due to the property of aluminum alloy materials that are easily deformed when heated, the joints between the frames are prone to defects such as burn-through and air holes, which makes the connection between the frames difficult and unsafe, increasing the safety risks of the automobile. Summary of the invention

[0005] To achieve the above object, the present invention provides the following technical solution: a wheel and vehicle body frame separation structure, comprising an inner side beam and a threshold outer plate arranged outside the inner side beam;

[0006] An anti-collision frame is arranged at one end of the inner side beam, a floor is arranged between the inner side beams, a reinforcement plate is arranged between the other ends of the inner side beams, and a front beam is also arranged between the inner side beams;

[0007] A seat front cross beam is arranged between the inner side beams, a seat rear cross beam is arranged on the right side of the seat front cross beam, a floor front cross beam is arranged on the right side of the seat rear cross beam, a connecting beam is arranged among the seat front cross beam, the seat rear cross beam and the floor front cross beam, a T-shaped connecting piece is arranged at the connection between the connecting beam and the seat front cross beam, a cross-shaped connecting piece is arranged at the connection between the connecting beam and the seat rear cross beam and the floor front cross beam, a T-shaped connecting piece is arranged on the T-shaped connecting piece, a cross groove is arranged on the cross-shaped connecting piece, and a plurality of mounting holes and reinforcing ribs are arranged on the T-shaped connecting piece and the cross-shaped connecting piece.

[0008] Preferably, the reinforcing ribs are welded to the T-shaped connector and the cross-shaped connector, and the reinforcing ribs can prevent the T-shaped connector and the cross-shaped connector from deforming. The T-shaped connector is fixed to the connecting beam and the front cross beam of the seat by screws, and the cross-shaped connector is fixed to the rear cross beam of the seat and the front cross beam of the floor by screws.

[0009] Preferably, the T-shaped connector and the cross-shaped connector are used to strengthen the connection between the connecting beam and the front cross beam of the seat, the rear cross beam of the seat and the front cross beam of the floor, thereby reducing the potential safety hazards and problems that may exist when only spot welding or welding is used.

[0010] Preferably, a pair of fixing parts are respectively provided on both sides of the front cross beam of the seat, the rear cross beam of the seat and the front cross beam of the floor, and a pair of reinforcing ribs are respectively provided on the fixing parts, the reinforcing ribs are welded to the fixing parts, and the fixing parts are fixed to the front cross beam of the seat, the rear cross beam of the seat and the front cross beam of the floor by screws.

[0011] Preferably, the inner side beam is welded to the door sill outer plate, and a side beam aluminum profile is arranged inside the inner side beam, and the side beam aluminum profile is embedded inside the inner side beam.

[0012] Preferably, a threshold aluminum profile is provided inside the threshold outer panel, the threshold aluminum profile is embedded in the threshold outer panel, and the threshold aluminum profile and the side beam aluminum profile are used to enhance the impact resistance of the inner side beam and the threshold outer panel.

[0014] Compared with the prior art, the present invention provides a structure in which the wheels and the vehicle body frame are separated, which has the following beneficial effects:

[0015] 1. The dual fixation of T-shaped connectors and cross-shaped connectors provides strong structural support to ensure the stability between the connecting beam and the cross beam. The secondary fixation effectively enhances the tensile and compressive resistance of the overall structure. The design of the reinforcing ribs can effectively prevent the deformation of the connectors in the event of a collision, thereby reducing the risk of injury to the occupants in the event of an accident. By strengthening key connection parts, the overall impact resistance of the vehicle body has been significantly improved. During the spot welding and welding connection process, weld defects such as burn-through and pores often occur, which may lead to a decrease in connection strength. Through this diversified connection method, the possibility of stress concentration and deformation during the welding process is reduced, thereby reducing safety hazards. This connection design helps to maintain the overall rigidity of the vehicle body, ensures that stress is evenly distributed between each connection point, and avoids premature degradation or fatigue of local materials.

[0016] 2. By embedding the side beam aluminum profile and the door sill aluminum profile into the inner side beam and the door sill outer panel, the lightweight and high-strength characteristics of aluminum are fully utilized to reduce the overall weight of the vehicle body while maintaining the strength and rigidity of the structure. The combination of the inner side beam and the door sill aluminum profile forms a solid structural frame that can effectively absorb and disperse the impact force generated during a side collision, reduce the direct impact on the passenger compartment, and thus improve the safety of the occupants.

The fixing parts 17 can effectively ensure the stability of the front cross beam 3 of the seat, the rear cross beam 4 of the seat and the front cross beam 5 of the floor between the inner side beam 1. The setting of this structure can effectively reduce the safety hazards caused by defects and defects such as burn-through and air holes that are prone to occur at the connection between the aluminum alloy skeletons when connecting by spot welding and welding, thereby greatly improving the safety and stability of the vehicle body frame.
