Description

Power layout structure of medium-sized electric vehicle

technical field

The utility model relates to an electric vehicle, in particular to a power arrangement structure of a medium-sized electric vehicle.

Background technique

Most of the existing electric vehicles are cars, passenger cars and small trucks, etc., because the required power is small, and the corresponding battery pack volume and weight are small, so its power system is better arranged. If the power system of a medium-sized vehicle also uses electric power, based on the application of the existing lithium battery, in order to meet the requirement of a medium-sized truck with a battery life of 300 kilometers, the capacity of the lithium battery pack should be guaranteed to be above 60,000AH. It is about 1.5 tons. When it is arranged on the vehicle, it is necessary to consider both the weight balance and the reasonable use of the position. Therefore, there is an urgent need to provide an improved power arrangement structure for medium-sized electric vehicles to overcome the above-mentioned defects.

Utility model content

The technical problem to be solved by the utility model is to provide a power layout structure of a medium-sized electric vehicle. With this layout structure, the weight distribution of the battery pack of the electric vehicle can be symmetrical, thereby ensuring the stability of the center of gravity and steering of the vehicle, and further ensuring the safe operation of the vehicle.

In order to solve the above technical problems, the utility model provides a power arrangement structure of a medium-sized electric vehicle, including a vehicle frame, a battery pack, a main drive motor, and a circuit control module electrically connected to the battery pack and the main drive motor. Both sides of the middle part of the vehicle frame are symmetrically provided with battery pack installation brackets, and a motor suspension bracket is provided under the vehicle frame. The battery pack includes a vehicle body battery pack installed in the battery pack mounting bracket and a head battery pack arranged under the driver's cab, and the main drive motor is installed in the motor suspension bracket.

Compared with the prior art, the battery pack of the medium-sized electric vehicle of the present invention is distributed under the driver's cab and on both sides of the middle of the vehicle. This arrangement structure makes the battery weight distribution symmetrical, thereby making the center of gravity and steering of the vehicle stable and ensuring the safety of the vehicle operation. . In addition, since the main drive motor is arranged under the vehicle frame, the center of gravity of the vehicle can be further stabilized and the included angle of the power transmission shaft can be ensured to be appropriate.

Preferably, the height of the main driving motor from the ground is greater than or equal to 250mm.

Preferably, the circuit control module is located under the driver's cab and above the front lithium battery pack, which is waterproof and easy to repair.

The utility model will become clearer through the following description in conjunction with the accompanying drawings, which are used to explain the embodiments of the utility model.

Detailed ways

Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the utility model provides a power layout structure of a medium-sized electric vehicle, which can make the weight of the electric vehicle symmetrically distributed, thereby ensuring the stability of the center of gravity and steering of the vehicle, and further ensuring the safe operation of the vehicle.

The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. As shown in Figures 1 and 2, the medium-sized electric vehicle of this embodiment includes a vehicle frame 1, a battery pack, a main drive motor 4, and a circuit control module 6 electrically connected to the battery pack and the main drive motor 4, so Said vehicle frame 1 is provided with cab 2 at one end. The circuit control module 6 may include a circuit controller and various electrical components.

Specifically, with reference to FIGS. 1-4 , the battery pack mounting bracket 7 is symmetrically provided on both sides of the vehicle frame 1 and a motor suspension bracket 8 is provided below it. In this embodiment, the battery pack mounting bracket 7 and the motor suspension bracket 8 are both located in the middle of the vehicle frame 1, but they are not limited thereto, and can be installed according to actual needs to balance the overall weight of the vehicle. The battery pack includes a vehicle body battery pack 3 installed in the battery pack mounting bracket 7 and a front battery pack 5 arranged under the cab 2 . The main driving motor 4 is installed in the motor suspension bracket 8 . The height of the main drive motor 4 can be set as required, but its height from the ground is preferably greater than or equal to 250mm. This structure can further stabilize the center of gravity of the vehicle and ensure that the included angle of the power transmission shaft is appropriate.

Preferably, the circuit control module 6 is located under the driver's cab 2 and above the front lithium battery pack 5, which is waterproof and convenient for maintenance.

The power arrangement structure in this embodiment rationally arranges the battery pack, the main drive motor, the electrical controller and electrical components, fully utilizes the vehicle body space, and ensures the balance and stability of the vehicle center of gravity.
