Embodiment 1

[0026] according to Figure 1-Figure 4 , a portable electric four-wheel vehicle chassis, which includes two symmetrically distributed longitudinal beams 2; the front and rear sides of the longitudinal beams are respectively connected vertically by the front beam 1 and the rear beam 8; the front beam and the rear beam It is in the shape of a rectangular frame, and the longitudinal beam is connected to the lower part of the front cross beam and the rear cross beam; the front support arm 3 and the rear support arm 7 are arranged on the longitudinal beam; one end of the front support arm and the rear support arm is respectively connected to the front cross beam and the upper part of the rear beam, and the other end is bent downward to connect with the longitudinal beam; the panel layer 4 is laid on the longitudinal beam and the rear support arm; the battery box 5 is arranged on the panel layer corresponding to the first two rows of seats; The battery box extends to the stringer wi...

Embodiment 2

[0035] The present invention improves the material and technology of the longitudinal beam, front cross beam, rear cross beam, cross brace, front support arm and rear support arm, so as to improve its comprehensive performance and reduce its weight. It is prepared by the following process:

[0036] First, add aluminum into the melting furnace, control the temperature between 700°C and 750°C to make it completely melted, and stir the aluminum liquid evenly;

[0037] Add AlMg20 accounting for 30% by weight of aluminum, AlTi5 of 10% by weight, AlNi10 of 5% by weight and AlCu50 of 1% by weight to the aluminum liquid in sequence, refining for 30 minutes, and after the refining is completed, all the slag in the aluminum liquid is completely Float to the surface and clean up the slag;

[0038] The alloy liquid is released from the furnace, cooled to 680°C, slowly poured into the sprue until it fills the entire mold cavity, cooled naturally, and then shelled to obtain a rough casting;...

Embodiment 3

[0052] The aluminum alloy property test of embodiment 2 of the present invention and comparative example 1-3:

[0053] The specific performance parameters are shown in Table 1:

[0054] Table 1

[0055] group Density g / cm 3

[0056] 2. Increasing the amount of magnesium will reduce the specific gravity of the alloy and improve the machinability, but adding too much magnesium will reduce the yield strength and hardness. Therefore, it is more important to choose the appropriate amount of magnesium, and set the amount of AiMg20 Accounting for 5%, 10%, 20%, 30%, 40%, 50% of aluminum respectively, such as Figure 5 As shown, with the increase of AiMg20, the yield strength decreases, but the decrease is small. When it increases to 40%, the yield strength decreases significantly. Therefore, it is more appropriate to choose the addition amount of 30%.

Abstract

The invention discloses a portable electric four-wheeler chassis which comprises two longitudinal beams distributed in a bilateral symmetry mode. The front face and the rear face of the longitudinal beam are perpendicularly connected through a front cross beam and a rear cross beam respectively. The front cross beam and the rear cross beam are in a rectangular frame shape, and the longitudinal beams are connected to the lower portions of the front cross beam and the rear cross beam. A front support arm and a rear support arm are arranged on the longitudinal beam; one ends of the front supportarm and the rear support arm are respectively connected to the upper parts of the front cross beam and the rear cross beam, and the other ends are bent downwards to be connected with the longitudinalbeams; and panel layers are laid on the longitudinal beams and the rear supporting arms. Battery boxes are arranged at the positions, corresponding to the front two rows of seats, on the panel layers.The chassis is reasonable in structure, by arranging the frame-shaped front cross beam, the frame-shaped rear cross beam, the front supporting arm and the rear supporting arm, the structural strengthof the chassis is improved, personnel and batteries on a vehicle are better protected when collision and scraping happen, the batteries are pushed, pulled, taken and placed in the battery box, a seatdoes not need to be moved, bolts do not need to be detached, and the defects of a portable electric four-wheeler chassis in the prior art are effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a chassis of a portable electric four-wheel vehicle. Background technique [0002] Scenic sightseeing vehicles, small sanitation vehicles and patrol vehicles mostly use portable electric four-wheel vehicles. This type of portable electric four-wheel vehicles has the advantages of low energy consumption, wide vision and low price. [0003] At present, the portable electric four-wheel vehicle mainly adopts a flat chassis, and 2-3 rows of seats are installed on the vehicle chassis, and a battery pack is arranged under the seats of the first row or the last row. This chassis has low structural strength. Shortcomings. The mileage of this kind of vehicle is about 100 kilometers and the time is about 3-5 hours, and the frequency of use of this kind of vehicle is relatively high, especially the patrol vehicle is used almost all day, and one charge cannot meet the n...
