[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0033] like Figures 1 to 6 As shown, an embodiment of the utility model provides a vehicle body structure, including a battery mounting portion 20 and a motor and electronic control mounting portion 30, wherein:

[0034] The battery mounting portion 20 is used to install and accommodate a power battery 40. The vehicle body structure includes a passenger compartment 10. The passenger compartment 10 has front seats 11 and rear seats. Compared with the prior art in which the power battery 40 is located below the rear seats, in the present application, the battery mounting portion 20 is arranged below the front seats 11, freeing up the front and rear space of the battery pack for the passengers in the vehicle, thereby maximizing the riding space.

[0035] The motor and electronic control installation part 30 is used to accommodate and install the motor 50 and the motor controller 60. Compared with the prior art, the motor 50 and the motor controller 60 are both arranged in the front cabin. In the present application, the motor and electronic control installation part 30 is arranged on the side of the battery installation part 20 away from the front direction of the vehicle, that is, it is arranged at the rear end of the vehicle body, which reduces the layout space requirement of the front cabin, increases the length of the front end collision crushing area, and expands the space of the passenger cabin 10.

[0036] The vehicle body structure provided in the above embodiment achieves maximization of the riding space by optimizing the layout structure of the motor and electronic control installation part 30 and the battery installation part 20 under a certain vehicle size.

[0037] In order to further expand the space of the passenger compartment 10, in the embodiment provided in the present application, reference is made to Figure 2 as well as Figure 3 As shown, the battery installation part 20 includes a front floor 21, which is located above the power battery 40, that is, on the side close to the front seats 11. The front floor 21 is designed as a "boss" structure to meet the installation space requirements of the power battery 40. Specifically, the front floor 21 includes a first plate 211, a connecting plate 212 and a second plate 213. The opposite ends of the connecting plate 212 are respectively connected to the first plate 211 and the second plate 213. The first plate 211 is farther away from the power battery 40 than the second plate 213. In the direction of gravity, the projection of the power battery 40 falls on the first plate 211, and the front seats 11 are installed on the first plate 211. The projection of the second plate 213 in the direction of gravity is offset from the front seats 11, thereby releasing the front and rear space of the battery pack for the occupants in the vehicle to maximize the riding space.

[0038] Reference Figure 3 As shown, in the length direction of the vehicle body, the projection of the power battery 40 at least partially falls on the connecting plate 212, and at least part of the power battery 40 can be accommodated in the groove at the bottom of the front floor 21 of the "boss" structure, thereby increasing the height of the power battery 40, increasing the ground clearance, and reducing the risk of bottom scraping and impact.

[0039] In a feasible implementation manner, the connecting plate 212 is tilted, and the connecting plate 212 is tilted in the length direction of the vehicle body. On the one hand, the overall strength of the front floor 21 can be enhanced. When the vehicle body is hit, when the collision force is transmitted to the connecting plate 212, part of the collision force can be transmitted forward, and part of the collision force can be transmitted upward, thereby more effectively dispersing the collision force, greatly improving the structural stability and safety. On the other hand, the space in front and behind the battery pack can be released to maximize the riding space in the passenger compartment 10.

[0040] In the embodiment provided in the present application, the battery mounting portion 20 includes a front floor beam 22, a rear floor beam 23 and a vehicle body beam 24. Two vehicle body beams 24 are provided, and the two vehicle body beams 24 extend along the length direction of the vehicle body. The front floor beam 22 and the rear floor beam 23 both extend along the width direction of the vehicle body. The opposite ends of the front floor beam 22 and the rear floor beam 23 are respectively connected to the two vehicle body beams 24 to form a frame structure, which improves the strength of the battery mounting point. When the vehicle body is hit, the frame structure can absorb a large amount of impact force well to ensure the structural stability of the battery mounting area. At the same time, the components of the frame structure utilize the structure of the vehicle itself, without the need for additional components. While reducing costs, the weight of the vehicle body is reduced, thereby achieving the goal of lightweighting the vehicle body.

[0041] The power battery 40 is respectively fixedly connected to the front floor beam 22, the rear floor beam 23 and the two body beams 24. When a collision occurs in the front of the vehicle body, the body beam 24 resists the collision and acts as a buffer. When the vehicle body is subjected to a lateral impact force, the external force is transmitted to the body beam 24 on the other side via the front floor beam 22 and the rear floor beam 23, which is convenient for the transmission and absorption of the collision force and improves the safety collision performance. The frame formed by the front floor beam 22, the rear floor beam 23 and the two body beams 24 bears the collision energy and reduces the collision damage to the power battery 40.

[0042] Further, refer to Figure 4 As shown, the power battery 40 forms at least two mounting points on the front floor beam 22 and the rear floor beam 23, and the power battery 40 forms at least one mounting point on a single vehicle body beam 24. In a feasible implementation manner, the mounting point of the power battery 40 is a bracket, and the bracket is an "L"-shaped structure. One side of the bracket is fixedly connected to the front floor beam 22, the rear floor beam 23 or the vehicle body beam 24, and the other side of the bracket is fixedly connected to the power battery 40 to improve the overall installation strength of the power battery 40. When the vehicle is subjected to collision impact in all directions, the power battery 40 is prevented from falling off from the mounting point. When the battery mounting portion 20 transmits the collision force, the strength and rigidity at the mounting point can be effectively improved.

[0043] Reference Figure 5As shown, the motor and electronic control installation part 30 includes a rear axle 31, a rear floor cross beam 23 and a rear floor longitudinal beam 32. The rear axle 31 extends in the width direction of the vehicle body, the motor 50 is fixed on the rear axle 31, the rear floor longitudinal beam 32 extends in the length direction of the vehicle body, the rear floor cross beam 23 extends in the width direction of the vehicle body, and the motor controller 60 is fixed on the rear floor longitudinal beam 32 and the rear floor cross beam 23 respectively. The fixing of the motor 50 and the motor controller 60 does not require additional components, which reduces the weight of the vehicle body while reducing the cost, thereby achieving the goal of lightweighting the vehicle body. The motor 50, the motor controller 60 and other components are moved to the rear end of the vehicle body, which increases the length of the front end collision crushing area, reduces the layout space requirement of the front cabin, and improves the comfort of the occupants.

[0044] In the embodiments provided in this application, refer to Figure 6 As shown, the vehicle body structure includes a front suspension 70 and a front panel 80. The front suspension 70 is closer to the front seat 11 than the front panel 80. The front panel 80 is designed in front of the front suspension 70. The steering wheel and three pedals are moved forward to realize the forward movement of the H point (the rotation point of the torso and thighs), thereby improving the comfort of the occupants.

[0045] Based on the vehicle body structure provided in the above embodiments, the utility model further provides a vehicle, which realizes maximization of the riding space by optimizing the structure of the passenger compartment 10 under a certain vehicle size through optimizing the layout structure of the motor and electronic control installation part 30 and the battery installation part 20, wherein the power battery 40 is arranged under the front seat 11, releasing the front and rear space of the battery pack for the passengers in the vehicle, and the motor and electronic control installation part 30 is moved to the rear end of the vehicle body, which reduces the layout space requirement of the front compartment, increases the length of the front collision crushing area, expands the space of the passenger compartment 10, and designs the front panel 80 in front of the front suspension 70, and moves the steering wheel and three pedals forward to realize the forward movement of the H point (the rotation point of the body trunk and thigh), thereby improving the comfort of the passengers.

[0046] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
