Description

Technical Field

[0001] This utility model relates to a battery holder, and more specifically, to a battery holder with a safety component positioning hole, and a battery pack using the same. Background Technology

[0002] A battery pack is constructed by placing multiple individual cells (hereinafter referred to as cells) in a battery holder and connecting them in series or parallel. The function of the battery holder is to position and fix the individual cells. When multiple cells are arranged adjacent to each other, if overheating occurs in one cell, the heat may spread to other cells. Therefore, heat-insulating materials are usually used as battery holders (see Patent Document 1).

[0003] To improve battery pack safety, safety components (such as PTC thermistors) are typically installed on certain cells within the pack to monitor the overall temperature of the battery pack. Generally, such as... Figure 7 As shown, the battery holder (1) has an upper surface (1a), a lower surface (1b), and a cavity between them for accommodating the battery (3). Furthermore, as... Figure 6 As shown, the upper surface (1a) of the battery holder (1) is provided with a battery holding hole (5) for positioning the battery (3) and an opening (4) for inserting a safety component (2) between adjacent batteries. The safety component (2) is inserted into the gap between two adjacent batteries (3) through the opening (4), and then thermally conductive silicone is injected. In this case, especially for cylindrical batteries with large volume, the gap between the batteries is large, which will waste a lot of silicone and waste filling time; moreover, when the battery pack is discharging at a large current, the air temperature in the gap between the batteries and the battery surface temperature are large, so this method is not applicable.

[0004] As an alternative, such as Figure 7 As shown, the safety component (2) can be attached to the side of a specific battery (3) using tape (6). At this time, the battery (3) suitable for attaching the tape (6) from the side is usually located at the edge of the battery holder (1). Therefore, the safety component (2) cannot accurately measure the temperature of the battery (3) located in the center of the battery pack, and the tape has low reliability and is easy to fall off in a humid environment. It has the disadvantages of multiple processes and low efficiency.

[0027] The specific form of the battery holder of this utility model will be described below with reference to the accompanying drawings.

[0028] Figure 1 This is a top view schematically showing the structure of the battery holder of this utility model.

[0029] The battery holder of this invention has an upper surface, a lower surface, and a cavity between the upper surface and the lower surface for accommodating the battery.

[0030] like Figure 1 As shown, the upper surface (1a) of the battery holder (1) is provided with a battery holding hole (5) for positioning the battery (3) and an opening (4) for inserting a safety component (2) between two adjacent batteries (3). The characteristic is that a safety component positioning hole (7) for positioning the safety component (2) is provided protruding from the opening (4), and the safety component (2) is tightly abutted against the side of the battery (3) through the safety component positioning hole (7).

[0031] By setting a safety component positioning hole (7) on the upper surface of the battery bracket (1), the safety component (2) can be conveniently positioned and fixed. The safety component (2) can be tightly attached to the battery surface without the need for tape. This can improve the reliability of the temperature collection of the safety component (2), fix the safety component (2), and reduce the installation time of the safety component (2).

[0032] In this manual, the term "safety component positioning hole" is sometimes simply referred to as "positioning hole". The size and shape of the positioning hole can be designed according to the size and shape of the safety component.

[0033] Figure 2 This is a partial perspective view schematically showing the structure of the battery holder of this utility model.

[0034] like Figure 2 As shown, the safety component positioning hole (7) is provided protruding from the opening (4), and its preferred shape is a groove with one side open, that is, it is open on the side adjacent to the battery (not shown), and the opposite side is a vertical baffle (7a). The safety component (not shown) located in the groove cavity can abut against the side of the battery through the baffle (7a).

[0035] By setting a baffle (7a), the safety component (2) can be tightly attached to the side of the battery (3) without the need for tape. Moreover, the inner volume of the positioning hole is small, which can reduce the amount of thermally conductive silicone and improve the reliability of the temperature acquisition by the safety component. In addition, multiple positioning holes (7) can be set according to the position of the opening (4) on the upper surface (1a) of the battery holder (1), preferably at least at the opening (4) near the center of the battery holder (1), thereby enabling accurate acquisition of the temperature of the battery (3) located at the center of the battery pack.

[0036] like Figure 2 As shown, in order to further enhance the contact force between the baffle (7a) and the safety component (2) and the battery (3), it is preferable to provide a first rib (8a) on the inner surface of the baffle (7a).

[0037] In addition, the safety component positioning hole (7) may also have two side edges (7b) perpendicular to the baffle (7a) on both sides of the baffle (7a) in the width direction, for limiting the movement of the safety component (2). Ribs may also be provided on the inner surface of the side edges (7b).

[0038] Figure 3 The following are schematic views (a) bottom view, (b) front view, (c) side view and (d) top view, showing the structure of the safety component positioning hole (7) in the battery holder of this utility model.

[0039] like Figure 3 As shown in (a), a first rib (8a) is preferably provided on the inner surface of the baffle (7a) of the safety component positioning hole (7), and a second rib (8b) is preferably provided on the inner surface of the two sides (7b). Additionally, as... Figure 3 As shown in (b), the preferred safety component positioning hole (7) also has a bottom surface (7c) for controlling the height of the safety component (2).

[0040] The safety component (2) can be confined within a small space by means of the side (7b) and bottom (7c) of the positioning hole (7), which prevents the safety component (2) from shaking and thus improves the working reliability of the safety component (2).

[0041] In addition, such as Figure 3 (c) and Figure 3 As shown in (d), the safety component positioning hole (7) may also have a top surface (7d) for protecting the safety component located in the safety component positioning hole.

[0042] The safety component positioning hole (7) can be an integral structure formed with the battery bracket (1), or it can be a separate structure formed separately from the battery bracket (1). The former has the advantages of simple installation process and improved work efficiency; while in the latter case, the safety component positioning hole (7) can be inserted or pulled out from any opening (4) on the upper surface of the battery bracket (1) as needed, which has the advantages of selectable number, flexible operation and high production efficiency.

[0043] Figure 4 This is a perspective view schematically showing the split structure of the safety component positioning hole in the battery holder of this utility model.

[0044] like Figure 4As shown, the split-type safety component positioning hole (7) also has a baffle (7a), two sides (7b), and a bottom surface (7c). During assembly, the safety component (2) can be fixed in the safety component positioning hole (7) first, and then inserted together with the positioning hole into any opening (4) on the upper surface of the battery holder (1). At this time, in order to facilitate monitoring of the battery temperature at the center of the battery pack, it is preferable to insert the safety component positioning hole (7) together with the safety component (2) into the opening (4) located near the center of the battery holder (1).

[0045] Figure 5 This is a perspective view schematically showing the state in which the above-mentioned split safety component positioning hole (7) is inserted into the battery gap.

[0046] like Figure 5 As shown, the safety component (2) is fixed in a relatively small space by the safety component positioning hole (7), which can reliably abut against the surface of the battery (3) and is led out to the outside from above. At this time, the safety component positioning hole (7) may or may not have a top surface (7d).

[0047] The shape and size of the safety component positioning hole (7) can be appropriately designed according to the shape and size of the battery used in the battery pack. The battery can be cylindrical, square or other shapes.

[0048] The number and location of the safety component positioning holes (7) on the battery holder can be determined according to the actual needs of the battery pack. For example, one or more holes can be provided in each row of batteries. In either case where the safety component positioning holes (7) are integrated or separate, a sufficient number of openings (4) or integrated safety component positioning holes (7) can be reserved in the battery holder. In this way, when in actual use, a safety component (2) or a positioning hole (7) with a safety component can be placed at a specific location in the battery pack, preferably near the center of the battery pack, as needed, so that the overall temperature of the battery pack can be monitored more effectively.

[0049] In addition, lead wire grooves can be provided in the safety component positioning holes (7) as needed to lead out battery leads.

[0050] This utility model also provides a battery pack, characterized in that it includes the above-mentioned battery bracket.

[0051] In this battery pack, specific positioning holes are designed on the battery bracket according to the size and shape of the safety component. Through the cooperation between the safety component and the baffle of the positioning hole, the safety component is made to fit tightly against the battery surface. Furthermore, the side and bottom of the positioning hole ensure that the safety component can only be fixed in a very small space. This not only improves the reliability of the temperature collection of the safety component, but also serves to fix the safety component, while reducing the installation time of the safety component and greatly improving work efficiency. It is especially suitable for battery packs with high current charging and discharging and multiple rows of batteries.

[0052] The battery bracket with safety component positioning holes and the wind turbine generator set of the present invention have been described above with reference to the accompanying drawings and specific embodiments. However, the present invention is not limited to the specific embodiments described above. Various modifications or changes of elements can be made without departing from the spirit of the present invention, and these modifications or changes of elements are also included within the protection scope of the present invention.
