Description

Technical Field

[0001] The utility model belongs to the field of electric vehicle bodies, and specifically relates to a front cabin assembly structure of an electric vehicle. Background Art

[0002] As a new energy vehicle, electric vehicles have a particularly important front-end collision avoidance performance because the driving position and various electronic hardware of electric vehicles are located in the front of the cabin. When the front of an electric vehicle collides, the main impact load is borne by the front cabin longitudinal beam of the electric vehicle, causing the front cabin to collapse or bend. If the impact load is too high, it is easy to cause the longitudinal beam or wheel arch to deform, move backward and occupy the space in the cabin, causing a safety accident. The body tends to be compact, which increases the risk of electrical hardware being squeezed. The design of the front cabin of a pure electric vehicle must not only install various electrical hardware in a limited space, but also ensure the structural strength of the body.

DETAILED DESCRIPTION

[0022] Figure 1 It is a structural schematic diagram of the front cabin assembly structure of an electric vehicle in an embodiment of the present utility model.

[0023] like Figure 1 As shown, the electric vehicle front cabin assembly structure provided by the present invention includes a front anti-collision beam 7, a left front longitudinal beam 11 and a right front longitudinal beam 2. The left front longitudinal beam 11 and the right front longitudinal beam 2 are respectively arranged on both sides of the front anti-collision beam 7. A left front longitudinal beam side cover plate 12 is provided on the left front longitudinal beam 11, and a right front longitudinal beam side cover plate 1 is provided on the right front longitudinal beam 2, which can enhance the structural strength, improve the collision safety of the electric vehicle, improve the compactness of the front cabin, and save costs.

[0024] The two ends of the front anti-collision beam 7 are provided with a front anti-collision beam right mounting connecting plate 6 and a front anti-collision beam left mounting connecting plate 10. The front anti-collision beam right mounting connecting plate 6 and the front anti-collision beam left mounting connecting plate 10 are respectively installed at the two ends of the front anti-collision beam 7 through bolt connection, providing installation positions for the left front longitudinal beam 11, the left front longitudinal beam side cover 12, the right front longitudinal beam 2 and the right front longitudinal beam side cover 1.

[0025] A front crossbeam mounting and connecting inner plate 8 is provided on the end of the left front longitudinal beam 11 near the front anti-collision beam 7, and the front crossbeam mounting and connecting inner plate 8 is connected to the front crossbeam left mounting and connecting plate 10, thereby connecting the left front longitudinal beam 11 and the front anti-collision beam 7. A front crossbeam left mounting and connecting outer plate 9 is provided on the end of the left front longitudinal beam side cover 12 near the front anti-collision beam 7, and the front crossbeam left mounting and connecting outer plate 9 is connected to the front crossbeam left mounting and connecting plate 10, thereby connecting the left front longitudinal beam side cover 12 and the front anti-collision beam 7, and then the left front longitudinal beam 11 and the left front longitudinal beam side cover 12 are connected by welding, and a left cavity is formed between the left front longitudinal beam 11 and the left front longitudinal beam side cover 12, constituting a hollow structure.

[0026] A front crossbeam right mounting connecting inner plate 4 is provided on the end of the right front longitudinal beam 2 close to the front anti-collision beam 7, and the front crossbeam right mounting connecting inner plate 4 is connected to the front crossbeam right mounting connecting plate 6, thereby connecting the right front longitudinal beam 2 and the front anti-collision beam 7. A front crossbeam right mounting connecting outer plate 5 is provided on the end of the right front longitudinal beam side cover 1 close to the front anti-collision beam 7, and the front crossbeam right mounting connecting outer plate 5 is connected to the front crossbeam right mounting connecting plate 6, thereby connecting the right front longitudinal beam side cover 1 and the front anti-collision beam 7, and then the right front longitudinal beam 2 and the right front longitudinal beam side cover 1 are connected by welding, and a right cavity is formed between the right front longitudinal beam 2 and the right front longitudinal beam side cover 1, constituting a hollow structure.

[0027] The hollow structure formed by the left cavity and the right cavity is beneficial to enhancing the collision safety of the left front longitudinal beam 11 and the right front longitudinal beam 2, and the front cabin assembly structure of the electric vehicle is symmetrical, and the left and right sides have the same structure, so that the impact load received by the front anti-collision beam 7 is evenly transmitted backward to the left front longitudinal beam 11 and the right front longitudinal beam 2, and the front end of the structure of the left front longitudinal beam 11 and the right front longitudinal beam 2 is small and the rear end is large. At the same time, the force-bearing cross-section of the hollow structure formed by the left cavity and the right cavity is a closed curve, so that the left front longitudinal beam 11 and the right front longitudinal beam 2 will gradually shrink and deform when impacted, and the stiffness in the front direction will gradually increase with the shrinkage of the left front longitudinal beam 11 and the right front longitudinal beam 2, which is beneficial for the left front longitudinal beam 11 and the right front longitudinal beam 2 to absorb more impact loads, reduce the impact of a frontal collision on the cabin, and reduce the possibility of injury to people in the cabin. In addition, when the front of the vehicle receives an offset collision, the left front longitudinal beam side cover 12 and the right front longitudinal beam side cover 1 are deformed by the impact pressure, which can disperse the load to the remaining connecting surfaces of the left front longitudinal beam 11 and the right front longitudinal beam 2. The hollow structure formed by the left cavity and the right cavity allows the longitudinal beams to have more collapse space and thus absorb more load, effectively playing a buffering role, reducing the impact on the internal electrical hardware of the front of the vehicle when the front of the vehicle receives a positive offset collision, reducing economic losses while reducing the safety hazard of power system loss of control caused by excessive squeezing of electrical hardware.

[0028] The electric vehicle front cabin assembly structure provided by the present invention also includes a power support crossbeam 3, the two ends of the power support crossbeam 3 are respectively connected to the left front longitudinal beam 11 and the right front longitudinal beam 2. The power support crossbeam 3 can be used to install electrical hardware and connect the left front longitudinal beam 11 and the right front longitudinal beam 2 at the same time. When the left front longitudinal beam 11 is deformed by impact, the load can be transferred to the right front longitudinal beam 2, or when the right front longitudinal beam 2 is deformed by impact, the load can be transferred to the left front longitudinal beam 11, thereby avoiding instability of the front cabin structure during a collision.

[0029] Figure 2 It is a schematic diagram of the internal structure of the right front longitudinal beam in the front cabin assembly structure of an electric vehicle in an embodiment of the present utility model.

[0030] A right front longitudinal beam reinforcement plate 13 is provided between the right front longitudinal beam 2 and the right front longitudinal beam side cover plate 1, and a left front longitudinal beam reinforcement plate is provided between the left front longitudinal beam 11 and the left front longitudinal beam side cover plate 12. The right front longitudinal beam reinforcement plate 13 and the left front longitudinal beam reinforcement plate can make the middle part of the right front longitudinal beam 2 and the left front longitudinal beam 11 thicker, increase local rigidity, reduce the degree of depression when subjected to pressure, and help reduce the extrusion of electrical components in the longitudinal beam when a collision occurs in the front of the vehicle.
