[0033] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] Reference Figure 1-3 This utility model provides a four-wheeled electric vehicle frame with a rear split, including a body 1 and a rear split 2. The rear split 2 and the body 1 can be separately set and detachably connected to form a non-load-bearing body 1. The rear split 2 can be used to install structures such as motors and shock absorption components, which can reduce maintenance difficulty and maintenance time.

[0035] The vehicle body 1 includes a frame 11 and a main beam 12. The main beam 12 is fixed inside the frame 11, and the main beams 12 are arranged in pairs and parallel to each other. One end of the main beam 12 extends out of the frame 11, and the end of the main beam 12 extending out of the frame 11 can be used to connect with the rear sub-body 2 of the vehicle frame.

[0036] The rear frame 2 includes a mounting bracket 21 and connecting beams 22. The connecting beams 22 are arranged in pairs, with one end of each connecting beam 22 fixed inside the mounting bracket 21. A connector 3 is fixed to the lower end of each connecting beam 22. The connector 3 has an inner groove, in which the main beam 12 can be placed. The main beam 12 can be bolted to the connector 3, allowing the main beam 12 and the connecting beams 22 to be disassembled, so that the vehicle body 1 and the rear frame 2 can be bolted together.

[0037] In this application, the vehicle body 1 and the rear frame 2 are detachably connected by the connecting beam 22 and the main beam 12. On the one hand, the suspension system can be installed on the rear frame 2, which can better absorb the impact from the road surface, reduce the vibration and noise of the vehicle body 1 during driving, and provide better ride comfort and handling performance. On the other hand, the transmission system and motor are located on the rear frame 2, which makes them easier to access and replace, reduces maintenance costs, and saves maintenance time.

[0038] It should be noted that the connecting beam 22 and the main beam 12 can also be directly connected, and the connection position does not have to be at the end of the connecting beam 22. In addition, other detachable connection structures can be used between the connecting beam 22 and the main beam 12, such as nut connection, detachable snap-fit ​​structure, etc.

[0039] The frame 11 includes two side members 111, and the main beam 12 includes a first beam 121, a second beam 122, and a composite beam 123. The side members 111, the first beam 121, and the second beam 122 are arranged in parallel. The composite beam 123 is fixed between the first beam 121 and the second beam 122. The second beam 122 extends out of the frame 11 and can be connected to the rear sub-section 2 of the frame.

[0040] Multiple first reinforcing beams 124 are fixed between the side rod 111 and the first beam 121. The first reinforcing beams 124 and the first beam 121 are arranged perpendicularly. A second reinforcing beam 125 is also provided within the frame 11. The second reinforcing beam 125 is fixed between the side rod 111 and the second beam 122, and between the two second beams 122. The second reinforcing beam 125 and the second beam 122 are fixed together. The first reinforcing beams 124 and 125 can improve the strength of the vehicle body 1. The first reinforcing beams 124 can be used to connect structural components of the vehicle body 1, and the second reinforcing beams 125 can be used to auxiliaryly connect with the rear sub-frame 2. It should be noted that more reinforcing beams at different positions can be provided between the frame 11 and the main beam 12 to improve strength and install the structure of the vehicle body 1. Those skilled in the art can modify these beams according to the specific vehicle body, shell, and seat positions.

[0041] Mounting frame 21 includes support rod 211, horizontal rod 212, bending rod 213 and connecting rod 214. Support rod 211, horizontal rod 212 and bending rod 213 are all arranged in pairs. Horizontal rod 212 and bending rod 213 are integral rods. A round rod 215 is fixed between the two horizontal rods 212. The round rod 215 is fixed to the end of the horizontal rod 212 away from the bending rod 213. Support rod 211 is fixed to the round rod 215.

[0042] Connecting rod 214 is fixed between horizontal rods 212, connecting beam 22 is fixed on connecting rod 214, and lug 216 is fixed on the lower side of connecting rod 214. Lug 216 is distributed on the side of the two connecting beams 22 that are far apart from each other. The mounting frame 21 can be used to accommodate the suspension and other structures of the four-wheeled vehicle. The two lugs 216 can fix the suspension structure respectively, so that the mounting frame 21 has the ability to install independent suspension and can adapt to the shock absorption requirements of electric four-wheeled vehicles.

[0043] The rear sub-frame 2 also includes a diagonal beam 23 fixed on the mounting bracket 21. One end of the diagonal beam 23 is fixed on a round rod 215, and the other end is fixed with a sleeve rod 24. The main beam 12 can be fitted with the sleeve rod 24, and the sleeve rod 24 can be detachably connected to the frame 11. Specifically, the sleeve rod 24 can be connected to the second reinforcing beam 125.

[0044] The sleeve 24 includes a horizontal plate 241 and a vertical plate 242, which are vertically connected. When the sleeve 24 is connected to the frame 11, the horizontal plate 241 and the vertical plate 242 can abut against the second reinforcing beam 125, and the horizontal plate 241 and the vertical plate 242 can be fixed to the second reinforcing beam 125 by bolts, so that the mounting bracket 21 can be connected to the main beam 12 and the frame 11 at the same time, so that there is sufficient connection strength between the vehicle body 1 and the rear subframe of the vehicle body.

[0045] As one embodiment, a crossbar 25 is provided inside the mounting bracket 21. The crossbar 25 is fixed between two curved bars 213. A longitudinal reinforcing bar 26 is fixed between the crossbar 25 and the connecting two bars, which can improve the strength of the rear subframe of the vehicle body.

[0046] As one embodiment, there is a gap 4 between the lower end of the support rod 211 and the sleeve rod 24, which can reduce the pressure of the mounting bracket 21 on the vehicle body 1 and reduce the road impact on the vehicle body 1.

[0047] As one embodiment, an equipment frame 5 is provided above the two main beams 12, and the aforementioned joint 3 is provided below the equipment frame 5. The joint 3 can be connected to the main beam 12 by bolts, which facilitates the fixing of motors and transmission structures and other structures in the mounting frame 21.

[0048] The implementation principle of this utility model is as follows: The vehicle body 1 and the rear frame 2 of this application are detachably connected by the connecting beam 22 and the main beam 12. On the one hand, the suspension system can be installed on the rear frame 2, which can better absorb the impact from the road surface, reduce the vibration and noise of the vehicle body 1 during driving, and provide better ride comfort and handling performance. On the other hand, the transmission system and motor are set on the rear frame 2, which makes them easier to access and replace, reduces maintenance costs, and saves maintenance time.
