[0002] As a part of the car, the battery provides starting current, power supply, and energy storage. The battery is usually fixed to the car body through a sheet metal structure. Due to the limited cabin space, existing plug-in hybrid cars generally place the battery in the rear floor area, which is generally placed on both sides or in the middle. If the battery is placed in the middle of the rear floor, the luggage space will be compressed. After the luggage space is compressed, the luggage that users can place will be reduced. If the battery is placed on both sides of the rear floor, it will affect the convenience of maintenance, and in the event of a collision, the battery is easily damaged and cannot work due to the relatively concentrated force on both sides.

[0003] In summary, the existing battery assembly installation structure has the following problems:

[0004] 1. The battery is located in the middle of the rear floor, and the battery is high, which occupies the trunk space. There is no longitudinal structural reinforcement beam at the bottom of the rear floor panel, which may cause the battery to be squeezed and damaged during a rear-end collision.

[0005] 2. The batteries are arranged on both sides of the rear floor, which affects the convenience of maintenance and is not conducive to maintenance operations.

[0006] A Chinese patent with application number 202111331989.0 discloses a lightweight cast aluminum battery mounting device assembly, including a cast aluminum front support plate, which is the main supporting structure of the mounting assembly. A two-level step is provided at the bottom of the cast aluminum front support plate, and the length of the two-level step is the same as the width of the cast aluminum front support plate. A card groove is provided on the outer surface of one end of the cast aluminum front support plate; a cast aluminum side support plate is located on the outer surface of the front end of the cast aluminum front support plate; a two-level platform edge is provided on the bottom surface of the end of the cast aluminum side support plate, and a top corner notch is provided on the outer surface of one end of the cast aluminum side support plate.

[0007] It is desirable to provide an improved battery assembly mounting device, particularly with regard to how to reduce the space occupied by the trunk. Summary of the invention

[0010] The battery tray is a hollow structure.

[0011] The battery tray comprises a tray body and an upper flange connected to the upper end of the tray body, and the upper flange is connected to the rear floor assembly.

[0012] The upper flange is arranged along the entire edge of the tray body.

[0013] The distance between the battery installation surface in the battery tray and the rear floor assembly is 80-85 mm.

[0014] The support mechanism includes a longitudinal beam connected to the rear floor body and the battery tray.

[0015] The longitudinal beam is U-shaped.

[0016] A protrusion is arranged on the longitudinal beam, and a positioning groove for the protrusion to be embedded is arranged at the bottom of the battery tray.
