Embodiment 1

[0057] A battery pack installation and connection device, including a battery pack 100 and a fixed connection device I210, the battery pack 100 and the fixed connection device I210 form a power battery system.

[0058] The fixed connection device I 210 includes an upper part 211 of the fixed connection device and a lower part 212 of the fixed connection device, and the upper part 211 of the fixed connection device and the lower part 212 of the fixed connection device respectively pass through the connection via hole structure 111 from the upper and lower directions, It is installed and fixed on the battery box and its mounting beam structure 110 in the form of shaft-hole fit. The connection method of shaft-hole fit is not limited to bolt connection, viscose connection, interference riveting, etc. Such as Figure 4 , Figure 5 shown.

[0059] The upper part 211 of the fixed connection device includes a flange bearing part I2111, a shaft hole connection part I2112 and a throu...

Embodiment 2

[0062] A battery pack installation and connection device includes a battery pack 100 and a fixed connection device II 220, the battery pack 100 and the fixed connection device form a power battery system.

[0063] Such as Figure 6 , Figure 7 As shown, the fixed connection device II 220 is a single bushing structure, and the fixed connection device II 220 passes through the connection via hole structure 111 and the battery box and its mounting beam structure 110 to be installed and fixed in the form of shaft holes. . The connection method of shaft hole fit is interference connection and bonding, or only interference connection.

[0064] The fixed connection device II220 flange bearing part III221, the shaft hole connecting part III222 and the through hole III223; the flange bearing part III221, the shaft hole connecting part III222 and the through hole III223 can be Platform expansion is realized by flexibly adjusting the structure size. The via holes III 223 are not limi...

Embodiment 3

[0068] A battery pack installation and connection method, the specific steps are:

[0069] Firstly, the main structure of the battery pack 100 is designed according to the installation and fixing requirements of the battery pack 100 in different vehicles, and the difference in coordinates of each mounting fixed point is identified;

[0070] Afterwards, according to different vehicles, two different fixed connection devices are designed for the position where there is a difference in coordinates of the mounting point of the battery pack 100;

[0071] Selecting the same fixed connection device for the same fixed point coordinates of the battery pack 100 for different vehicle models;

[0072] Finally, through the structural coupling between the battery pack 100 and the fixed connection device combination 200 composed of several fixed connection devices matching different vehicles, the mount matching of different vehicles is realized.

Abstract

The invention relates to a battery pack mounting and connecting device, a connecting method and a vehicle, the connecting device comprises a battery pack and a fixed connecting device group, the fixed connecting device group consists of at least one fixed connecting device, the battery pack and the fixed connecting device form a power battery system, and the power battery system is fixedly connected with the vehicle. The vehicle comprises the power battery system applying the battery pack and the fixed connecting device. By means of the battery pack installation connection design method and device, application maximization of the same battery pack platform can be achieved, the variety of battery pack products is reduced, and the research and development cost is reduced; the fixed connecting device has compatibility and generalization, and can be adapted to different battery packs; the structure is simplified, the size is small, the overall size is not affected when configuration changes, the structure is compact, the space utilization rate of the vehicle and the battery pack can be effectively increased, and then the driving range of the vehicle is increased; the battery pack and the connecting device have the advantages of simplicity in assembly and disassembly, easiness in process implementation and the like.

Description

technical field [0001] The invention belongs to the technical field of new energy electric vehicles, and in particular relates to a battery pack installation and connection device, a connection method and a vehicle. Background technique [0002] The development of electric vehicles has become an inevitable trend in the automotive industry. Battery packs account for a large proportion of both material costs and development costs. The platform application of battery packs is an important means to effectively control costs. [0003] During the development of electric vehicles, due to differences in the Z-direction position coordinates of the battery pack mounting points of different vehicles, the same battery pack cannot be carried at the same time. In the existing technology, a special adaptation structure is usually designed in the battery pack to realize the loading, which not only increases the occupied space, but also reduces the energy density of the battery pack. At the...
