[0034] Traditional battery boxes can only be placed upright during transport, but different usage scenarios have different requirements, and the single upright placement mode is insufficient. For example, outdoor portable power supplies may be used on sloping surfaces or bumpy vehicles, and the requirement of upright placement makes it difficult for the equipment to operate stably, easily leading to power outages, loose batteries, and poor contact. Emergency rescue and field exploration equipment often face complex terrain and variable operating conditions, and the limitation of upright placement reduces the reliability of the equipment, causing it to be unable to provide normal power supply at critical moments. In some special situations, it is even necessary to place the battery box upside down, so the traditional battery box structure can no longer meet the needs.

[0035] The main purpose of this invention is to propose a battery box that aims to at least solve the problem of the limited placement options in related technologies.

[0036] Please see Figures 1 to 3 In one embodiment of the present invention, the battery box 100 includes a box body 1, a plurality of battery cells 2 and a pressing assembly 3. The box body 1 has a receiving cavity, the plurality of battery cells 2 are disposed in the receiving cavity, and the pressing assembly 3 includes a pressing rod 31 detachably disposed in the receiving cavity, the pressing rod 31 abutting against the upper ends of the plurality of battery cells 2.

[0037] In the technical solution of this utility model, the battery box 100 includes a box body 1, a plurality of battery cells 2, and a clamping assembly 3. The box body 1 has a receiving cavity, and the plurality of battery cells 2 are disposed in the receiving cavity. The clamping assembly 3 includes a pressure rod 31 detachably disposed in the receiving cavity. The pressure rod 31 abuts against the upper ends of the plurality of battery cells 2. Thus, when the plurality of battery cells 2 are installed in the receiving cavity, the pressure rod 31 is also installed in the receiving cavity, and the pressure rod 31 is set to clamp the upper ends of the plurality of battery cells 2. In conjunction with the bottom wall of the receiving cavity, the plurality of battery cells 2 are fixed, so that the plurality of battery cells 2 can remain stable in various scenarios.

[0038] It is understood that different battery cells 2 have different heights. If the pressure rod 31 is only detachable within the receiving cavity, the pressure rod 31 will not function properly when the battery module composed of multiple battery cells 2 has different heights. Therefore, in this embodiment of the utility model, the pressure rod 31 is movable in the vertical direction. In this way, the height of the pressure rod 31 can be adjusted according to the battery cells 2 of different heights. When the heights of the battery cells 2 are different, the pressure rod 31 can also press them down, thus expanding its applicability.

[0039] In order to allow the pressure rod 31 to be detached from the receiving cavity and to move vertically, in the embodiment of this utility model, please refer to... Figure 1 and Figure 2The length direction of the pressure rod 31 is in the first horizontal direction. The clamping assembly 3 also includes two fixing members 32 and bolts 33. The two fixing members 32 are respectively fixedly installed on the two side walls of the receiving cavity in the first horizontal direction. The pressure rod 31 is slidably installed on the fixing members 32 in the vertical direction. The bolts 33 are used to fasten the pressure rod 31 and the fixing members 32. With this configuration, when it is necessary to remove the pressure rod 31, the bolts 33 can be completely loosened, so that the fixing members 32 and the pressure rod 31 can be completely separated, and the pressure rod 31 can be removed. When it is necessary to adjust the height of the pressure rod 31, the bolts 33 can be completely loosened or slightly loosened, so that the position of the pressure rod 31 can be adjusted. Then, according to the height of the battery cell 2, the fixing members 32 and the pressure rod 31 are fixed in a suitable position by the bolts 33, and the height of the pressure rod 31 can be adjusted.

[0040] In another embodiment, a snap-fit ​​structure, such as a snap-fit ​​block and a snap-fit ​​groove, can be provided between the side wall of the receiving cavity and the pressure rod 31. For example, when the snap-fit ​​block is provided on the pressure rod 31 and the snap-fit ​​groove is provided on the side wall of the receiving cavity, multiple sets of snap-fit ​​grooves of different heights can be provided. Thus, according to the height of the battery cell 2, the snap-fit ​​block on the pressure rod 31 is changed to snap-fit ​​with the snap-fit ​​groove of different heights, thereby adjusting the height of the pressure rod 31.

[0041] Specifically, in this embodiment, the fixing member 32 has a groove 321 extending in the vertical direction, and the groove 321 is open on both sides in the second horizontal direction; each end of the pressure rod 31 has two clamping arms 311 arranged opposite each other in the second horizontal direction, and the fixing member 32 is disposed between the two clamping arms 311; the bolt 33 is disposed on the two clamping arms 311 and passes through the groove 321. Thus, when it is necessary to adjust the height of the pressure rod 31, the nut of the bolt 33 is loosened so that the two clamping arms 311 do not clamp the fixing member 32. In this way, the pressure rod 31 can move in the vertical direction relative to the fixing member 32, and the bolt 33 can also move in the groove 321. After moving to the appropriate position, the nut of the bolt 33 can be tightened to squeeze the two clamping arms 311, thereby clamping the fixing member 32 by the two clamping arms 311, and completing the fixation of the pressure rod 31.

[0042] The adjustment method using the bolt 33 is not limited to this. In another embodiment, multiple first through holes of different heights can be provided on the fixing member 32, and corresponding second through holes can be provided on the pressure rod 31. In this way, the pressure rod 31 and the fixing member 32 can also be fixed at different heights using the bolt 33.

[0043] The clamping arm 311 and the pressure rod 31 can be integrally formed or separate. Comparatively, when the clamping arm 311 and the pressure rod 31 are separate, they need to be manufactured separately before being fixed together, which is more cumbersome. Therefore, in this embodiment of the invention, the clamping arm 311 and the pressure rod 31 are integrally formed; this makes production more convenient.

[0044] There are several ways to integrally form the clamping arm 311 and the pressure rod 31. For example, in some embodiments, they can be integrally formed by injection molding. In some embodiments, the end of the pressure rod 31 is provided with a groove 312 that matches the fixing member 32 to form two clamping arms 311. In comparison, injection molding is more expensive, requires the design of a suitable injection mold, and when the size of the fixing member 32 is different, the injection mold needs to be designed again. After injection molding, the clamping arms 311 also need to be processed so that the two clamping arms 311 can correctly clamp the fixing member 32. By cutting the groove 312 at the end of the pressure rod 31, it is only necessary to cut according to the size of the fixing member 32. Even if the size of the fixing member 32 is different, only different cutting heads need to be changed during cutting, making production more convenient.

[0045] It is understandable that the more pressure rods 31 there are, the better the fixing effect on the multiple battery cells 2. However, correspondingly, a larger number of rods will also make installation and disassembly more troublesome. In order to enable one pressure rod 31 to fix more battery cells 2, in some embodiments, please refer to... Figure 3 The length direction of the pressure rod 31 is a first horizontal direction; the plurality of battery cells 2 includes two battery packs arranged along a second horizontal direction, and each battery pack includes a plurality of battery cells 2 arranged along the first horizontal direction; the pressure rod 31 abuts against the junction of the upper ends of the two battery packs. This arrangement allows the pressure rod 31 to fix the two battery packs, and with a fixed volume of the receiving cavity, this configuration can fix more battery cells 2.

[0046] Of course, such as Figure 3 The single pressure bar 31 shown can only press one end of the battery pack. In order to ensure the fixing effect, when there are two battery packs, two additional pressure bars 31 can be set, that is, the number of pressure bars 31 is three, to fix both ends of the two battery packs. Even so, compared with the four pressure bars 31 required to fix only one battery pack, the number of pressure bars 31 will be less.

[0047] To further secure more of the battery cells 2, in some embodiments, the battery cells 2 are elongated along the vertical direction; the width direction of the battery cells 2 is a first horizontal direction. Thus, within the same volume of the receiving cavity, a greater number of battery cells 2 can be distributed in the first horizontal direction, meaning the pressure rod 31 can secure more of the battery cells 2.

[0048] Of course, in order to ensure the fixing effect of the pressure rod 31, the size of the pressure rod 31 in the second horizontal direction can be set to be large enough, if space permits.

[0049] The pressure rod 31 can be in rigid contact or flexible contact with the battery cell 2. When the pressure rod 31 is made of a rigid material, it is in rigid contact with the battery cell 2, which provides a better fixing effect. When a buffer pad is provided on the lower side of the pressure rod 31, it is in flexible contact with the battery cell 2, which can reduce the possibility of damage caused by the pressure rod 31 squeezing the battery cell 2.

[0050] In order to reduce the heat transfer between the battery cells 2, in the embodiments of this utility model, a thermal pad 4 is provided between the battery cells 2.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
