Description

TECHNICAL FIELD

[0001] The utility model relates to the field of new energy vehicles, more particularly, the utility model relates to an integrated vehicle battery mounting rack. BACKGROUND

[0002] With the support of the national new energy policy, the use of pure electric new energy vehicles is becoming more and more widespread, and the amount of use is becoming larger and larger. Among them, the power battery pack is a key part of the new energy electric vehicle big three electricity, which is not only a power supply unit of the whole vehicle, but also an energy storage device of the whole vehicle power. In order to ensure the safety and assembly reliability of the battery pack, the strength of the bracket structure and the convenience of installation need to be ensured during the design process to ensure sufficient strength and reliable performance.

[0003] At present, in the truck series models, the mainstream installation method of battery pack is to adopt square battery pack structure, and the arrangement is usually in the form of two boxes and four boxes, arranged on both sides of the frame. Because the battery pack occupies a large space, different battery installation methods and quantities of different manufacturers have a great impact on the arrangement of the whole vehicle, and because there is a lack of unified fixed design, other chassis parts are relatively scattered, the overall chassis part mounting structure is scattered and complex, which is not easy to install and causes weight redundancy. CONTENT OF THE UTILITY MODEL

[0009] The accessory support is arranged on the crossbeam and / or the longitudinal beam.

[0010] The utility model takes into account the two kinds of electric quantity box arrangements on the market, and uniformly designs the battery frame mounting structure. According to the different electric quantity and different specification battery pack structure of the whole vehicle, the overall structure and size of the battery frame body are considered. And the accessory support is fixed and integrated on the mounting rack, which avoids the problem of scattered parts. After the whole battery is installed, the battery mounting rack can be installed on the automobile chassis as a whole through the frame connecting piece.

[0011] A further technical scheme is that the crossbeam is provided with a water cooling unit support.

[0012] The water-cooled unit support surrounds a water-cooled unit installation position, and the water-cooled unit support is provided with a fixing device.

[0013] The water-cooled unit is a whole unit for providing water cooling for the battery, and includes an adjustable power compressor, a condenser, an evaporator (plate exchanger), an expansion valve, refrigerant high and low pressure pipelines, a control unit, a heat dissipation fan, a water pump and other components. By reserving a water-cooled unit position in the battery mounting rack, the overall size of the battery frame is kept uniform in the water-cooled unit state and the non-water-cooled unit state, so that the overall frame is not different, and the arrangement positions of other chassis parts are not affected.

[0014] Further, the accessory support includes any one or several of an air compressor support, an air cylinder support, a drying tank support, a charging port seat support, a storage battery support, an expansion water tank support, a water pump support, a PTC support, a PDU support, a water pump controller support, a high-voltage box support, and a handle switch support.

[0015] The accessory support is provided with a fixing device.

[0016] The PTC is composed of a PTC ceramic heating element and an aluminum pipe. This type of heating body has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater.

[0017] The PDU provides functions of charging and discharging control, high-voltage component power-on control, circuit overload and short circuit protection, high-voltage sampling, low-voltage control and the like for the high-voltage system of a new energy vehicle, so as to ensure safe operation and monitoring of the high-voltage system.

[0018] Further, the integrated vehicle battery mounting rack further includes a battery frame body cover.

[0019] The battery frame body cover is in the shape of a Chinese character 'n', and includes a left cover, a right cover, and a bottom plate.

[0020] The battery frame body cover can improve the overall strength and provide additional protection.

[0021] Further, the left cover and the right cover are provided with an accessory auxiliary device.

[0022] The accessory auxiliary device includes any one or several of a water-cooled grid hole, a charging port small door, a handle switch small door, and an MSD maintenance door.

[0023] The accessory auxiliary device provided on the left cover and the right cover is mainly used for facilitating installation and maintenance operations, and the installation position of the accessory auxiliary device corresponds to the position of the accessory support.

[0024] Compared with the prior art, the utility model has at least the following beneficial effects: The utility model considers arranging and installing various battery capacity battery frames as a whole. Through the lower layer structure design of the battery frame body, the overall size of the battery frame body is adapted to the installation of various battery capacities. Further, through the overall arrangement design of the bottom disc, multiple components are integrated on the battery frame body for installation, avoiding separate assembly on the frame girder. The problem of various vehicle arrangements, scattered and various complex whole vehicle structures and structural weight redundancy in the prior art is solved. At the same time, centralized arrangement and unified arrangement can greatly improve production and assembly efficiency. BRIEF DESCRIPTION OF DRAWINGS
