Embodiment 1

[0025] The battery pack fixing device of the electric vehicle is arranged on the bottom of the vehicle body 1, and the battery pack fixing device includes a mounting bracket 2, a flexible connector, a guide mechanism and a positioning mechanism, and the battery pack 3 can be fixed on the body 1 by the device, and Easy to assemble and disassemble.

[0026] Specifically, the flexible connector can make the mounting bracket hang below the vehicle body. In this embodiment, the flexible connector is four hinges 5, such as figure 2 As shown, one end of the hinge 5 is fixedly connected to the mounting bracket 2, and the other end is fixedly connected to the vehicle body 1, so that the mounting bracket 2 can move up and down in a direction perpendicular to the bottom of the vehicle body 1. In the actual production and assembly process, the number of hinges 5 is not limited to four, and the number of hinges 5 can be selected according to actual installation requirements and the load o...

Embodiment 2

[0031] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the guide mechanism includes slide rails (21) that open the inner side of the mounting bracket (2), and the battery pack ( 3) Be provided with the chute (31) that cooperates with slide rail (21) on.

Embodiment 3

[0033] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1. The difference is that in this embodiment, the positioning mechanism includes a clamping hole fixed on the mounting bracket 2 and a hole fixed on the lower side of the vehicle body 1. The buckle on the top, the buckle can be snapped into the card hole. When disassembling, it is only necessary to use a tool to separate the buckle from the card hole, and the mounting bracket 2 can move downward, so that the battery pack can be easily removed from the mounting bracket 2 .

Abstract

The invention provides a battery pack fixing device of an electric vehicle, belonging to the technical field of electric vehicles and solving the problems of incapability of realizing position regulation in the vertical sliding rail moving direction and inconvenience for installation of the traditional battery pack fixing device of the electric vehicle. The battery pack fixing device comprises an installation bracket capable of placing a battery pack, wherein a flexible connecting member is connected between the installation bracket and a vehicle body, the flexible connecting member can ensure that the installation bracket is suspended below the vehicle body, a guide mechanism capable of enabling the battery pack to slide front and back is arranged on the installation bracket, and a positioning mechanism capable of enabling the installation bracket and the vehicle body are fixed in positions relatively in the vertical direction is arranged between the installation bracket and the vehicle body. The installation bracket of the battery pack fixing device of the electric vehicle is provided with a hinge for hinging the installation bracket with the vehicle together, and the installation bracket can move up and down in the direction of the vehicle body vertical to the bottom so as to be convenient for installing the battery pack in the installation bracket and positioning the battery pack and the vehicle body.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to an electric vehicle, in particular to a battery pack fixing device for the electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Electric vehicles include electric drive and control systems, transmission systems, and driving control systems. The electric drive and control system is the core of the electric vehicle. The electric drive and control system is composed of a drive motor, a power supply, and a speed control device for the motor. The power supply provides electrical energy to the drive motor of the electric vehicle. [0003] At present, electric vehicles have relatively large battery packs, which require special battery pack transportation and installation equipment for installation. And the function of supporting the battery pack. In addition, the...
