Stamping two-layer module tray, liquid cooling system, liquid cool tray assembly and battery pack

Abstract

The invention relates to a stamping two-layer module tray, a liquid cool system, a liquid cooled tray assembly, and a battery pack. The stamping two-layer module tray comprises a tray body made by a stamping molding process. That upper side of the tray body is stamped with a plurality of limiting structures cooperating with the liquid cooling system on the battery module and limiting the positionof the liquid cooling system. The stamping two-layer module tray is formed by stamping process. Compared with sheet metal tailor-welded tray, the process is simple, a large number of machining processes and equipment can be saved, and the cost can be reduced. A plurality of limit structures are arranged on the pallet body, which can effectively prevent the liquid cooling system from sliding and prevent the liquid cooling system from being damaged by impact.

Description

technical field

[0001] The invention relates to the field of new energy technology, in particular to a stamped two-layer module tray, a liquid cooling system, a liquid cooling tray assembly and a battery pack. Background technique

[0002] At present, the global automobile industry is facing the huge challenge of energy and environmental issues; pure electric vehicles with high energy utilization rate and no pollution to the environment are increasingly becoming the development direction of the future automobile industry. As the core component of a pure electric vehicle, the structural design and safety performance of the power battery pack will directly affect the overall performance of the pure electric vehicle. Since the installation space reserved for battery packs in pure electric vehicles is small and irregular in shape, in order to make full use of the limited space of battery packs, it is often necessary to arrange two-layer modules, and the design of two-layer modul...

Embodiment 1

[0050] Such as Figure 1-Figure 4 As shown, a stamped two-layer module tray in this embodiment includes a tray body 100 made by a stamping process. The upper side of the tray body 100 is stamped with several holes that match the liquid cooling system on the battery module 600. A limiting structure 101 for limiting the liquid cooling system is combined. Wherein, each of the limiting structures 101 includes at least two limiting surfaces 102 abutting against the liquid cooling system, and at least two limiting surfaces 102 abutting against the liquid cooling system are arranged on the limiting structure 101, so that The liquid cooling system abuts against the corresponding limiting surfaces to prevent sliding.

[0051] Specifically, such as figure 1 with figure 2As shown, the module tray of this embodiment adopts a rectangular structure matched with the battery box, and is set as a concave structure, and a number of bosses 107 are formed upwardly on the bottom of the tray bo...

Embodiment 2

[0061] Such as Figure 5 with Image 6 As shown, a liquid cooling system in this embodiment includes a liquid cooling plate 400 and several elastic members 500 clamped at the bottom of the liquid cooling plate 400 , and the liquid cooling plate 400 is crimped on the tray body 100 , the elastic member 500 is adapted to abut against the limiting structure 101 on the upper side of the module tray. Specifically, each elastic member 500 abuts against each limiting surface 102 of the limiting structure 101 respectively, that is to say, each elastic member 500 can prevent the liquid cooling system from shaking.

[0062] Wherein, the material of the elastic member 500 can be plastic, metal, etc., as long as the elastic member can be restored after a force is exerted on the material.

[0063] Such as Figure 5-Figure 9 As shown, a preferred solution of this embodiment is that the elastic member 500 is an arc-shaped sheet structure, the middle part of the elastic member 500 is clampe...

Embodiment 3

[0068] Such as Figure 5 with Image 6 As shown, a liquid cooling tray assembly of this embodiment includes the module tray described in Embodiment 1 and the liquid cooling system described in Embodiment 2; On the limit structure 101 on the upper side of the tray body 100 . The liquid-cooled tray assembly of this embodiment can effectively support and cool the battery pack, and also greatly improve the overall performance of vibration resistance and shock resistance.

[0069] A preferred solution of the liquid cooling tray assembly of this embodiment is, as Figure 1-Figure 4 As shown, a plurality of limiting structures 101 are punched and formed on the module tray, and each limiting structure 101 is parallel to each other and extends toward the upper surface of the tray body 100 . The liquid cooling system includes a plurality of liquid cooling plates 400, each liquid cooling plate 400 is arranged parallel to each other and located on the same plane, and the bottom of each...
