Problems solved by technology

[0003] When the installation part is subjected to external force, especially when the installation part is subjected to lateral impact, due to the height difference between the first part and the second part of the installation part, and the connection between the first part and the second part through the third part, the installation The structural strength of the first part is low, and the third part is easy to bend and deform under the action of external force, so that the mounting part is deformed and damaged, and then the battery tray is easily deformed and the single cells inside are damaged, which is not conducive to protecting the single cells inside the battery tray. body battery

Embodiment Construction

[0054]Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0055] In this disclosure, unless stated otherwise, the used orientation words such as "up and down" are generally relative to the normal driving state of the vehicle, specifically, towards the direction of the roof of the vehicle when the vehicle is running normally. is "up", and the direction toward the vehicle chassis is "down"; in addition, "vertical" refers to the up and down direction of the vehicle, that is, the Z direction shown in the drawings, and "lateral" refers to the direction perpendicular to the vertical , that is, the front-rear and left-right directions of the vehicle, the X and Y directions shown in the drawings; in addition, "inside and out...

Abstract

The present disclosure relates to a battery tray, a power battery pack, and a vehicle. The battery tray includes a tray body and a plurality of mounting seats. Ribs are formed on the tray body, and a plurality of mounting lugs are formed on the edge of the tray body. The mounting lugs and The tray body is integrally formed, the mounting seat is arranged under the corresponding mounting lug and is connected with the corresponding mounting lug and the tray body respectively, a first cavity is formed between the mounting seat and the mounting lug, and the mounting seat is arranged on the rib ends. Through the above technical solution, the first cavity is formed between the mounting seat and the mounting lug, which can increase the bending resistance section coefficient and prevent deformation, and the mounting lug and the tray body are integrally formed, and the force transmission effect is good. In addition, the mounting seat is set on At both ends of the reinforcing rib, when the mounting seat is subjected to external force, the mounting seat first transmits the force to the reinforcing rib and then to the tray body, which is more conducive to the transmission and dispersion of force.

Description

technical field [0001] The present disclosure relates to the technical field of power batteries, and in particular, to a battery tray, a power battery pack using the battery tray, and a vehicle using the power battery pack. Background technique [0002] Existing battery trays generally include a bottom plate and side plates arranged around the bottom plate. The bottom plate and the side plates jointly define an accommodation space for accommodating single batteries. The battery tray is usually provided with a mounting plate for installing the battery tray on the vehicle body. part, the installation part includes a first part and a second part parallel to each other, and a third part formed between the first part and the second part, the first part of the installation part is connected with the upper edge of the side plate of the battery tray, and the installation support The second part of the seat is connected to the bottom plate of the battery tray, and there is a height d...
