[0026] Next, the embodiments of this specification are described in detail.
[0027] Please refer to Figures 1 to 4As shown, the present application provides a vehicle body, including: a side panel 10 and a first floor assembly 20 fixed to the side panel 10. Along the width direction of the vehicle, the side panel 10 is located outside the first floor assembly 20, a first fixing position is provided on the side panel 10, and the first floor assembly 20 is fixed to the first fixing position. A second fixing position is also provided on the side panel 10, and along the height direction of the vehicle, the second fixing position is located above the first fixing position, and the first floor assembly 20 can be removed from the first fixing position and fixed to the second fixing position.
[0028] In one embodiment, the first floor assembly 20 of the vehicle body provided in the present application can be switched between a first fixed position and a second fixed position to adjust the height of the first floor assembly 20, without the need to separately manufacture two side panel molds including the first fixed position or the second fixed position, thereby saving costs and shortening the development cycle.
[0029] The first fixing position and the second fixing position described in the present application are merely nicknames for two different fixing positions of the first floor assembly 20 on the side panel 10. The second fixing position described in the present application is located above the first fixing position for the purpose of convenient description. In fact, it can be understood that the first floor assembly 20 has a fixed position on the side panel 10, and the first floor assembly 20 can be removed from the side panel 10 and fixed to another fixed position on the side panel 10. Along the height direction of the vehicle, the upper fixed position of the two fixed positions is referred to as the second fixing position in the present application, and the lower fixed position is referred to as the first fixing position. The first fixing position and the second fixing position do not limit the specific position of the first floor assembly 20 on the side panel 10, nor do they limit the number of fixed positions of the first floor assembly 20 on the side panel 10. The first floor assembly 20 can continuously adjust the fixed position on the side panel 10, thereby adjusting the height of the first floor assembly 20. Along the height direction of the vehicle, a height difference H1 between the first fixing position and the second fixing position is greater than or equal to 50 mm and less than or equal to 150 mm, thereby reserving sufficient space to accommodate components such as the engine or rear longitudinal beam or rear cross beam that need to be placed in the case of rear-wheel drive.
[0030] The length of the side panel 10 along the vehicle height direction should be greater than the height difference H1 between the first fixing position and the second fixing position, and considering the deviation during actual installation, a certain gap should be left between the first floor assembly 20 and the end of the side panel 10. Therefore, preferably, the length of the side panel 10 should be 15 mm or more greater than the height difference H1 between the first fixing position and the second fixing position.
[0031] The vehicle body provided in the present application further includes a second floor assembly 30 connected to the side panel 10. The first floor assembly 20 is connected to the second floor assembly 30, and the second floor assembly 30 is located in front of the first floor assembly 20 along the driving direction of the vehicle.
[0032] When the first floor assembly 20 is located at the first fixed position, the first floor assembly 20 is flush with the second floor assembly 30 along the height direction of the vehicle; when the first floor assembly 20 is located at the second fixed position, the first floor assembly 20 is higher than the second floor assembly 30 along the height direction of the vehicle.
[0033] When the first floor assembly 20 is located at the first fixed position, the first floor assembly 20 is flush with the second floor assembly 30, and the first floor assembly 20 and the second floor assembly 30 can be connected by welding; if the first floor assembly 20 is located at the second fixed position, the first floor assembly 20 is higher than the second floor assembly 30, and the first floor assembly 20 is connected to the second floor assembly 30 through the connecting plate 40, and the first floor assembly 20 and the second floor assembly 30 can be respectively connected to the two ends of the connecting plate 40 by welding, screwing, riveting, gluing, etc.
[0034] The side panel 10 includes a side panel outer panel 11 and a side panel inner panel 12 connected together, and the side panel outer panel 11 and the side panel inner panel 12 form a cavity, and the cavity allows a certain gap to be retained between the side panel outer panel 11 and the side panel inner panel 12 to prevent the side panel outer panel 11 from deforming due to an accident such as a collision, thereby affecting the side panel inner panel 12. The first floor assembly 20 and the second floor assembly 30 are connected to the side panel inner panel 12.
[0035] The side inner panel 12 includes a mounting portion 121 and a reinforcement portion 122 extending from the mounting portion 121 . The first floor assembly 20 is mounted to the mounting portion 121 , and at least a portion of the reinforcement portion 122 is wavy, thereby improving the connection strength between the side inner panel 12 and the side outer panel 11 .
[0036] In the height direction of the vehicle, the reinforcement portion 122 extends upward from the mounting portion 121 and is connected to the upper end of the side outer panel 11, and the mounting portion 121 is connected to the lower end of the side outer panel 11. Figure 4 As shown, the wavy reinforcement structure of the reinforcement portion 122 may be two, three or even more, and the wavy reinforcement structure of the present application may be arranged at the reinforcement portion 122 near the upper end of the side outer panel 11, or may be arranged at the reinforcement portion 122 near the mounting portion 121. The present application does not impose any restrictions on this.
[0037] The difference between the height of the mounting portion 121 along the vehicle height direction and the height difference between the first mounting position and the second mounting position should be greater than or equal to 15 mm, so as to reserve enough space to accommodate the first mounting position and the second mounting position.
[0038] The first floor assembly 20 includes a floor body 21 and a lap portion 22 that is bent and extended to one side from the floor body 21. The height of the lap portion 22 is greater than or equal to 14 mm and less than or equal to 16 mm. The lap portion 22 is attached to and fixed to the mounting portion 121, thereby fixing the first floor assembly 20 to the side panel 10, thereby improving the connection strength between the first floor assembly 20 and the side panel 10.
[0039] The overlapping portion 22 can be fixed to the mounting portion 121 by welding, or by screwing, or by other reasonable connection methods with sufficient connection strength, and the present application does not limit this.
[0040] A plurality of reinforcing ribs 23 are disposed on the floor body 21, so that the floor body 21 has a high structural strength and prevents the floor body 21 from being deformed by passengers stepping on it.
[0041] The first floor assembly 20 also includes a plurality of cross beams 24 and a plurality of longitudinal beams 25 disposed below the first floor assembly 20. The cross beams 24 and the longitudinal beams 25 can effectively disperse the stress and vibration generated during the driving of the vehicle, thereby improving the rigidity and stability of the entire vehicle body; they can absorb part of the impact energy during a collision, reduce the impact of the collision on the vehicle occupants, and improve the safety of the vehicle; they can also serve as a supporting structure to connect and support the vehicle's engine, chassis components, etc., to make the entire vehicle structure more stable.
[0042] The present application also provides a vehicle, including the vehicle body of the above-mentioned vehicle, when the first floor assembly 20 is flush with the second floor assembly 30 in terms of vehicle height, the vehicle is driven by the front wheels; when the first floor assembly 20 is higher than the second floor assembly 30 in terms of vehicle height, the vehicle can be front-wheel driven, rear-wheel driven, or four-wheel driven.
