Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery boxes, and specifically relates to a battery pack tray. Background Art

[0002] In new energy vehicles, the battery pack is the source of its power; the battery pack will generate heat during the charging and discharging process, which will affect the safety and working efficiency of the battery pack.

[0003] Therefore, current battery packs will adopt a highly efficient cooling and highly sealed battery pack box and manufacturing method such as patent number "202310567440.4". This solution uses a liquid cooling plate to reduce the heat of the battery pack during charging and discharging, and then places the battery pack by surrounding a fixed-size lateral enclosure with a frame.

[0004] In the above scheme, the battery pack is composed of a combination of several batteries. Battery packs of different specifications have different numbers and sizes of batteries. When the specifications of the battery pack change, the size of the lateral enclosure must also change accordingly, resulting in changes in the size of the frame and the liquid cooling plate. That is, new specifications of the frame and liquid cooling plate need to be adopted, which makes installation and production very cumbersome.

[0005] Therefore, it is necessary to design a battery pack tray that can accommodate battery packs of various specifications. Utility Model Content

[0006] The purpose of the utility model is to provide a battery pack tray to solve the technical problems described in the background technology.

[0007] In order to solve the above technical problems, the utility model provides a battery pack tray, which includes: a liquid cooling plate, three sides of which are bent toward one side; and a limiting plate, which is arranged on the liquid cooling plate and encloses the three sides of the liquid cooling plate to form a battery cavity for placing the battery pack; wherein the width of the limiting plate is adapted to the size of the battery cavity.

[0008] Furthermore, a reinforcing plate is provided on the bottom surface of the liquid cooling plate.

[0009] Furthermore, the reinforcing plate is provided with a mounting groove for accommodating the liquid cooling plate.

[0010] Furthermore, a plurality of weight-reducing holes are provided at the bottom of the installation groove.

[0011] Furthermore, both side edges of the limiting plate in the width direction are bent toward the liquid cooling plate.

[0012] Furthermore, the middle portion of the limiting plate is folded inwardly along the length direction to form a sealing edge; wherein the sealing edge is in contact with the liquid cooling plate.

[0013] The beneficial effect of the present utility model is that, in order to adapt to battery modules of various specifications, the battery pack tray is provided with three sides of the liquid cooling plate being bent, and one side being left unbent, so as to form a battery cavity of adjustable size; after the required battery pack is assembled, the limiting plate is placed close to the battery pack, and the battery pack is enclosed together with the three bent sides of the liquid cooling plate; wherein, when the specifications of the battery pack change, it is only necessary to select a limiting plate of corresponding width for installation according to the size of the battery pack.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 4 As shown, this embodiment provides a battery pack tray, which includes: a liquid cooling plate 1, three sides of which are bent toward one side; and a limiting plate 2, which is arranged on the liquid cooling plate 1 and forms a battery cavity 11 for accommodating the battery pack with the three sides of the liquid cooling plate 1; wherein the width of the limiting plate 2 is adapted to the size of the battery cavity 11.

[0028] In the present embodiment, specifically, the battery pack in the battery cavity 11 is composed of a plurality of batteries, and the battery pack is assembled by selecting a corresponding number of batteries according to the required specifications. Since the sizes of battery packs of different specifications are different, in order to adapt to battery modules of various specifications, in the present embodiment, three sides of the liquid cooling plate 1 are bent and one side is left unbent to form a battery cavity 11 of adjustable size. After the required battery pack is assembled, the limiting plate 2 is placed close to the battery pack and the battery pack is enclosed by the three bent sides of the liquid cooling plate 1. When the specifications of the battery pack change, it is only necessary to select a limiting plate 2 of corresponding width according to the size of the battery pack for installation.

[0029] In this embodiment, the liquid cooling channel of the liquid cooling plate 1 is located at the bottom of the battery cavity 11 .

[0030] like Figure 5 , Figure 6 As shown, in this embodiment, a reinforcing plate 3 is provided on the bottom surface of the liquid cooling plate 1 .

[0031] In this embodiment, the reinforcing plate 3 is provided with a mounting groove 31 for accommodating the liquid cooling plate 1 .

[0032] In this embodiment, a plurality of weight-reducing holes 32 are formed at the bottom of the installation groove 31 .

[0033] In this embodiment, specifically, the role of the reinforcing plate 3 is to increase the supporting strength of the bottom of the liquid cooling plate 1 to prevent the liquid cooling plate 1 from being deformed by force; the mounting groove 31 is adapted to the size of the bottom of the liquid cooling plate 1, and the side of the mounting groove 31 also acts as a frame, replacing the traditional profile frame; the bent edge 12 of the liquid cooling plate 1 is provided with a flange 13, and the flange 13 is attached to the reinforcing plate 3 and fixed by a fixing member.

[0034] like Figure 3 , Figure 7 As shown, in this embodiment, both side edges of the limiting plate 2 in the width direction are bent toward the liquid cooling plate 1 .

[0035] In this embodiment, the middle portion of the limiting plate 2 is folded inwardly along the length direction to form a sealing edge 21 ; wherein the sealing edge 21 is in contact with the liquid cooling plate 1 .

[0036] In this embodiment, specifically, both side edges of the limiting plate 2 in the width direction are bent toward the liquid cooling plate 1, so that a certain height can be formed to block the battery pack; the sealing edge 21 in the middle fits with the liquid cooling plate 1 to play a sealing role (it can be fixed with glue), so that the battery cavity 11 surrounded by the limiting plate 2 and the liquid cooling plate 1 can be turned into a cavity sealed on all sides, preventing rainwater from entering the battery cavity 11 from the limiting plate 2.

[0037] To summarize, in order to adapt to battery modules of various specifications, the battery pack tray has three sides of the liquid cooling plate 1 bent, leaving one side unbent, to form a battery cavity 11 of adjustable size. After the required battery pack is assembled, the limiting plate 2 is placed close to the battery pack, and the battery pack is enclosed by the three bent sides of the liquid cooling plate 1. When the specifications of the battery pack change, it is only necessary to select a limiting plate 2 of corresponding width according to the size of the battery pack for installation.
