① The battery is arranged at the rear lower part of the rear seat, the motor front, and the front wheel drive. The front -wheel drive method makes the vehicle structure compact, which is conducive to the arrangement of other assembly systems, and the stability of driving stability during steering and acceleration is better. However, when the uphill is reduced, the front wheels are reduced and easy to slip; the front -wheel drive and steering, the structure is complicated, making the vehicle maintenance inconvenient. In addition, the battery occupies the space of the rear seat.

② The battery is arranged under the floor of the chassis and the floor of the seat. In this form of layout, the battery is scattered horizontally, which can ensure that the carriage has a large riding space, and the suitcase also has a large loading space.

③ The battery is arranged in the luggage behind, the motor is front, and the front wheel drive. This layout form can achieve a wider riding space, and the luggage space is lost. Similarly, the battery can also be front, the motor is rear, and the rear wheel drive is conducive to the uniform distribution of the car load of the car.

④ The wheel driver motor is used to directly drive the driver wheel of the electric vehicle. The battery can be arranged at the bottom of the body, or in the suitcase. This layout structure is simple and saves space.

2. Analysis of the layout of electric cars

Due to the flexible characteristics of electric vehicle structures, the form of layout can have many forms. The layout of the electric vehicle battery pack should be considered: the shape, size and wire connection method of the unit battery, safety, the load distribution of the front and rear axles, the control of heat dissipation and temperature, the maintenance and replacement convenience. In addition, the spatial layout, the quality of the vehicle, and the location of the heart must be considered.

3. The overall layout of electric vehicles

Considering the structure of the original car, the battery is arranged in the luggage, the front of the motor, and the front -wheel drive structure layout. The driving system of the original car is retained. The motor output end is connected to the input terminal of the speed, and the left and right wheels are driven by the differential output of the differential output. In order to make the front and rear axle distribution reasonable, to ensure that the car has good dynamicity, passability, and manipulation stability, the layout of the power battery is dispersed.

(1) Design of the layout of key components of the front cabin

On traditional gasoline cars, the front cabin is a concentrated land of core components, and key components such as engines and transmission are basically arranged in the front cabin. Similarly, electric vehicles also put some key components in the front cabin, such as motor controllers, motors, reducers, electric vacuum pumps, electric air conditioners, etc., mainly because:

① There are many special parts of electric vehicles, and there is basically no space in other locations in the vehicle. After the front cabin removes the engines, transmission and other related parts, a certain space has been emptied.

② For electric passenger cars, front -drive front -wheel drive is still a relatively effective form of driving. Therefore, most of the current models are arranged in the front cabin.

③ The motor controller, motor, etc. are large -volume parts, which is more conducive to improving the overall work efficiency. Coupled with the reducer, a more effective layout method is required. So basically choose to put it in the front cabin.

Of course, in the actual project design process, due to the limited space of pure electric passenger bicycles, and due to many components, high -voltage wiring, etc., it is very difficult to arrange. Improve.
