Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage liquid-cooled battery packs, and particularly relates to a liquid-cooled PACK with a movable connector board. Background Technique

[0002] With the rapid development of the new energy industry, energy storage technology has developed and risen rapidly in new energy. Related liquid-cooled battery pack (PACK) products have become the focus of research and development in the energy storage industry. As an important main component unit in energy storage products, the relevant design of the liquid-cooled battery pack has received more attention.

[0003] A liquid-cooled battery pack usually consists of several square battery cells to form a battery module, and several battery modules form a battery pack. A plurality of jacks and plugs are provided on the outer shell of the battery pack, facilitating operators to connect through wires and then use the electric energy stored in the battery module. However, the exposed jacks and plugs will pose a safety hazard of electric shock to operators during handling or installation.

[0004] In the prior art, usually a cover plate is added outside the exposed jacks and plugs to protect the plugs and jacks. However, the cover plate is usually fixed with screws. When the operator fixes the cover plate, there is still a safety hazard of electric shock due to directly touching the conductive part. At the same time, the number of screws required to be added on the cover plate is relatively large, which will greatly reduce the production efficiency of the liquid-cooled battery pack.

[0005] Therefore, there is an urgent need for a liquid-cooled battery pack that can install the protective cover plate conveniently and safely, so that the production efficiency of the liquid-cooled battery pack is greatly improved, and at the same time, the liquid-cooled battery pack becomes safer and more reliable in the production of the whole pack. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art, the utility model provides a liquid-cooled PACK with a movable connector board to solve the technical problems that the installation of the cover plate on the liquid-cooled battery pack is cumbersome and there are safety hazards during installation.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0008] A liquid-cooled PACK with a movable connector board includes a liquid-cooled plate, a housing, an upper cover, a plug-in mounting board, and a plurality of battery modules. The plurality of battery modules are sequentially fixed on the liquid-cooled plate. The housing is sleeved outside each battery module, and the bottom is fixed to the liquid-cooled plate.

[0009] One side of the housing is provided with an installation through groove that cooperates with the plug-in mounting plate. The plug-in mounting plate is slidably connected to the installation through groove. The plug-in mounting plate can move inward to form an installation area with the installation through groove. The upper cover is embedded and fixed in the installation area. The battery module is communicated with the socket on the plug-in mounting plate.

[0010] Further, the plug-in mounting plate is L-shaped. Two waist-shaped holes are symmetrically arranged on the bottom surface of the plug-in mounting plate. The length directions of the two waist-shaped holes are aligned with the opening direction of the installation through groove. Step screws are arranged in both of the two waist-shaped holes. The bottom of the step screw is fixedly connected to the liquid cooling plate.

[0011] Further, a fixed seat is integrally formed on the liquid cooling plate. The step screw passes through the waist-shaped hole and its bottom is threadedly connected to the fixed seat.

[0012] Further, the length of the waist-shaped hole is 17 mm.

[0013] Further, the step screw is an M4x12 step screw.

[0014] Further, each battery module is connected to the socket on the plug-in mounting plate through a flexible copper busbar.

[0015] Further, a silicone insulation cap is sleeved on the connection end of the flexible copper busbar and the socket on the plug-in mounting plate.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] In the utility model, an installation through groove that cooperates with the plug-in mounting plate is opened on one side of the housing. The plug-in mounting plate is slidably connected to the installation through groove. The plug-in mounting plate can move inward to form an installation area where the upper cover can be embedded and fixed between the plug-in mounting plate and the installation through groove, avoiding danger caused by touching the conductive part during the process of screwing and fixing the upper cover.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] The present invention will be further described below with reference to the drawings.

[0025] As Figure 1 and 2 shown, a liquid-cooled PACK with a movable plug-in board includes a liquid cooling plate 1, a housing 2, an upper cover, a plug-in mounting plate 3 and a plurality of battery modules 4. Among them, the plurality of battery modules 4 are sequentially fixed on the liquid cooling plate 1. The housing 2 is sleeved outside each battery module 4 and is locked and fixed at the bottom by screws. An installation through slot 6 for cooperating with the plug-in mounting plate 3 is opened on one side of the housing 2. The plug-in mounting plate 3 is slidably connected at the installation through slot 6.

[0026] During use, the plug-in mounting plate 3 can move inward relative to the outer end opening of the installation through slot 6, so that an installation area is formed between the plug-in mounting plate 3 and the outer opening of the installation through slot 6. The upper cover is embedded and fixed in the installation area, protecting each wiring hole on the plug-in mounting plate 3 and at the same time avoiding the danger caused by the operator accidentally touching the conductive part directly when fixing the upper cover because the installation of the plug-in mounting plate 3 requires screw fixation.

[0027] The specific structure is, as Figure 3 and 4 shown, the plug-in mounting plate 3 is L-shaped. Two kidney-shaped holes 5 are symmetrically opened on the bottom surface of the plug-in mounting plate 3. The length directions of the two kidney-shaped holes 5 are aligned with the opening direction of the installation through slot 6. Stepped screws 7 are provided in both of the two kidney-shaped holes 5. The bottom of the stepped screw 7 is fixedly connected to the liquid cooling plate 1. The setting of the stepped screw 7 limits the movement of the plug-in mounting plate 3 in the vertical direction and in the direction deviating from the length direction of the kidney-shaped hole 5, so that the plug-in mounting plate 3 can only move inward or outward along the length direction of the kidney-shaped hole 5, that is, the direction of the opening of the installation through slot 6.

[0028] Furthermore, a sealing strip is fixed on the outer vertical surface of the plug-in mounting plate, which is used to fill the gap between the plug-in mounting plate and the housing in the initial state, and the gap between the outer vertical surface of the plug-in mounting plate and the upper cover after the upper cover is fixedly embedded.

[0029] Furthermore, an integrally formed fixing seat 8 is provided on the liquid cooling plate 1. The stepped screw 7 passes through the kidney-shaped hole 5 and is threadedly connected to the fixing seat 8 at the bottom.

[0030] In this embodiment, the length of the kidney-shaped hole 5 is 17 mm. The stepped screw 7 is a stepped screw 7 of M4x12.

[0031] Furthermore, a flexible copper busbar 9 is provided between each battery module 4 and the socket on the plug-in mounting plate 3 for conduction. A silicone insulation cap 10 is sleeved on the connection end of the flexible copper busbar 9 and the socket on the plug-in mounting plate 3. The flexible copper busbar 9 enables the plug-in mounting plate 3 to undergo adaptive deformation during horizontal movement, avoiding the inability of the plug-in mounting plate 3 to move due to the excessive hardness of the copper busbar material.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
