Embodiment 1

[0032] The modular hub electric drive vehicle of the present invention has a structure such as figure 1 As shown, a modular structure is adopted, including a frame-type body, a modular shell, and a hub drive module installed on the frame-type body chassis. The main structure includes a front cover 1, a door 2, a steering wheel 3, and a front pillar 4 , upper side rail 5, seat 6, center pillar 7, rear pillar 8, rear wall upper cover 9, right rear fender 10, rear wall 11, hub motor 12, lower side rail 13, wheels 14, front support plate 15, front lamp 16, right front fender 17, rear lamp 18, left rear fender 19, left front fender 20. The frame body is made up of aluminum profiles, wherein the front pillar 4, the middle pillar 7 and the rear pillar 8 form the frame of the upper body. A total of four wheels 14 are equipped with in-wheel motors 12, and are connected to the chassis girder through a double wishbone suspension. The four wheels can simultaneously drive the entire vehic...

Embodiment 2

[0034] The modular hub electric drive vehicle of the present invention has a structure such as figure 2 As shown, another different appearance of the car shell can be obtained through the front support plate 15, the front cover plate 1, the car door 2, the rear wall upper cover plate 9, and the rear wall plate 11.

Embodiment 3

[0036] A vehicle with a modular body and wheel-hub electric drive adopts a modular structure, including a frame-type body, a modular shell, and a wheel-hub drive module installed on the chassis of the frame-type body.

[0037] The hub drive module includes hub motors, double-wishbone suspensions and cables. There are four hub motors, which are respectively connected to the wheels and directly drive the four wheels of the vehicle. The hub motors are connected to the frame-type body chassis through double-wishbone suspensions. On the girder, cables transmit drive signals. The hub motor is a 4kW small hub motor with a maximum speed of 750rpm. The four in-wheel motors drive the vehicle simultaneously through two sets of inverters, and the four-wheel in-wheel motors are directly driven without gearboxes and transmission shafts, greatly improving energy efficiency.

[0038]The frame-type body is composed of a front frame, a middle frame and a rear frame made of aluminum profiles. ...

Abstract

The invention relates to a wheel-type electrically driven vehicle of a modular body. The vehicle with a modular structure comprises a frame-type body, a modular replaceable shell and a wheel drive module installed on a frame-type body chassis, wherein the wheel drive module comprises four wheel motors, a double-wishbone suspension and cables. The four wheel motors are respectively connected with four wheels and directly drive the four wheels of the whole vehicle, the wheel motors are connected on a beam of the frame-type body chassis through the double-wishbone suspension, and the cables are used to transmit driving signals. Compared with the prior art, the wheel-type electrically driven vehicle of the modular body has the advantages of a modular and light body structure, a replaceable shell to meet the needs of diverse appearance and the like. Furthermore, with the use of the four-wheel drive mode, distributed drive and modular assembly of the wheel-type electrically driven vehicle of the modular body is easy.

Description

technical field [0001] The invention relates to an electric drive vehicle, in particular to an electric drive vehicle with a modular body and hub type. Background technique [0002] At present, the trend of electrification of automobiles is becoming more and more obvious, and the use of clean energy has brought more development ideas to the structural design of automobiles. In particular, vehicles that use in-wheel motors to realize the distributed configuration and independent control of driving force can fully utilize their advantages and potential in control structure, and can realize a more flexible modular vehicle design. For electric vehicles equipped with in-wheel motors, the application of independent traction motors means that the torque loaded on each wheel can be controlled independently, making the feature of flexible control especially obvious. By taking full advantage of the excellent control capabilities of the electric drive system, electric vehicles show us...
