Description

A front crossbeam structure of a vehicle frame and a vehicle

Technical Field

The utility model relates to the technical field of automobile parts, in particular to a front crossbeam structure of a frame and an automobile.

Background Art

Pure electric van models are mainly used for short-distance cargo transportation. They have large cargo box space and compact passenger compartment and front cabin space. To ensure the vehicle's head-on collision performance, it is necessary to design a front crossbeam at the front section of the frame to absorb the frontal impact energy. The front bumper, front crossbeam, and radiator of pure electric van vehicles are arranged in sequence from front to back along the X direction. The front bumper is provided with an air inlet. The traditional front crossbeam of the frame adopts a straight design or a convex arc design, which will block the wind entering the front air inlet, affecting the air intake of the radiator directly behind, resulting in insufficient cooling performance of the air conditioner; to ensure that the radiator has sufficient air intake and the cooling performance of the air conditioner, it is often necessary to design a deflector between the front bumper and the radiator, resulting in the addition of new parts and a significant increase in development costs.

Utility Model Content

The first purpose of the utility model is to provide a front crossbeam structure of a vehicle frame to solve the problem that in the prior art, in order to ensure sufficient air intake for the front radiator of the vehicle, a new air deflector needs to be designed, which leads to a significant increase in development costs; the second purpose of the utility model is to provide a vehicle.

In order to achieve the above first purpose, the technical solution adopted by the utility model is:

A front crossbeam structure of a vehicle frame includes a front crossbeam body, the middle portion of which is bent upwards and has an arc shape; and its cross section is a U-shape with an opening facing backwards, including a top plate and two opposite side plates, and a plurality of air inlet holes are arranged at intervals along the length direction on the top plate.

The utility model adopting the above-mentioned technical solution designs the front cross beam body to be an upwardly arched arc, so that it is partially offset from the air inlet on the front bumper in the height direction, thereby reducing the obstruction of the front cross beam body to the air intake, and the airflow at the front end of the vehicle can flow through the bottom of the front cross beam body into the radiator, thereby increasing the air intake of the radiator; at the same time, a plurality of air inlet holes are arranged on the front cross beam body, and the airflow at the front end of the vehicle can enter the radiator through the air inlet holes, thereby further increasing the air intake of the radiator. Compared with the prior art, in order to ensure sufficient air intake of the radiator at the front end of the vehicle, it is necessary to design a new air deflector, which leads to a significant increase in development costs. The utility model adopts the front cross beam body with the above-mentioned structure, thereby significantly increasing the air intake of the radiator, which is sufficient to ensure the cooling performance of the air conditioner without the need to design new air deflector parts, thereby reducing development costs.

Furthermore, two symmetrical sunken platforms are provided on the top plate of the front crossbeam body, and the sunken platforms are both strip-shaped and arranged along the length direction of the top plate; the air inlet holes include a plurality of left air inlet holes and right air inlet holes arranged symmetrically on the left and right, and the two are respectively arranged on the two sunken platforms; opening the above-mentioned left air inlet holes and right air inlet holes on the front crossbeam body will weaken its strength. By setting two sunken platforms at the air inlet holes, the rigidity and strength of the place can be enhanced, thereby preventing the opening of the air inlet holes from weakening the head-on collision performance of the front crossbeam body.

Furthermore, a plurality of the left air inlet holes are arranged at equal intervals, and a plurality of the right air inlet holes are arranged at equal intervals, and the intervals between the two are equal; with such an arrangement, the air volume entering the radiator is more uniform, which is beneficial to improving the heat dissipation effect.

Furthermore, both ends of the two side panels of the front crossbeam body are provided with connecting plates extending outward, and any of the connecting plates is provided with a frame front crossbeam mounting hole; a total of four connecting plates at both ends of the front crossbeam body are bolted to the surrounding connecting parts, so the connection is firm, and it is easy to disassemble and assemble, and convenient for maintenance.

Furthermore, a trailer hook through hole is provided on the right end of the top plate of the front cross beam body, so that the trailer hook can pass through and connect with the longitudinal beam.

Furthermore, both ends of the top plate of the front cross beam body are provided with installation positioning holes, which facilitate positioning during installation and improve assembly efficiency.

Furthermore, the side panel located at the bottom of the front cross beam body is provided with a plurality of outwardly extending ears, and the ears are arranged at intervals along the length direction; any of the ears is provided with a mounting hole, and the plurality of mounting holes include at least a front cabin wiring harness mounting hole, a temperature sensor mounting hole, a right-hand drive millimeter-wave radar mounting hole and a right-hand drive wiring harness mounting hole; such an arrangement can be compatible with right-hand drive vehicles, and has good integration and compatibility.

To achieve the second purpose, the utility model adopts the following technical solutions:

A car comprises the above-mentioned front cross beam structure of the frame.

Compared with the prior art, the beneficial effects of the utility model are as follows: the front crossbeam body adopting the above-mentioned structure greatly increases the air intake of the radiator, which is sufficient to ensure the cooling performance of the air conditioner without the need to design new deflector parts, thereby reducing development costs; the automobile has the same technical effects as the aforementioned frame front crossbeam structure.
