DETAILED DESCRIPTION

[0032] The following will describe in detail a specific embodiment of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the description 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.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0034] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0035] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0036] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0037] The utility model provides a bracket 1, such as Figures 1 to 7 As shown, the bracket 1 is used to surround the module 2, and includes a first mounting portion and a second mounting portion. The first mounting portion is used to connect with the module 2, and the second mounting portion is used to connect with the packaging box 3. The module 2 can be installed and fixed to the packaging box 3 through the bracket 1. In this embodiment, the bracket 1 is arranged around the module 2, which can limit the increase of the outer size caused by the expansion of the module 2 during the charge and discharge test, thereby improving the size qualification rate of the module 2; and the module 2 is installed and fixed to the packaging box 3 through the bracket 1. On the one hand, the bracket 1 used to limit the expansion of the module 2 has a strong structural strength and is not easy to deform. The module 2 is connected to the packaging box 3 through the bracket 1, and the part of the bracket 1 used to connect the packaging box 3 is not easy to change in size, which is convenient for the positioning and installation of the bracket 1 and the packaging box 3. On the other hand, the packaging box 3 is usually a wooden box. If the module 2 is directly connected to the packaging box 3 through a connecting piece such as a bolt, the wooden box with low hardness is prone to torque attenuation and thus affects the connection stability between the module 2 and the packaging box 3. The module 2 is now connected to the packaging box 3 through the bracket 1. The module 2 and the bracket 1 can achieve a relatively stable hard connection through a connecting piece such as a bolt, which is not easy to torque attenuate, and the looseness, friction or bump between the module 2 and the packaging box 3 is transferred to the bracket 1 and the packaging box 3, which is conducive to improving the fixing stability and reliability of the module 2 and the packaging box 3, and improving the protection of the module 2.

[0038] Specifically, after the mounting holes 5 are punched in the packing box 3, if the size of the module 2 changes after the charge and discharge test, the mounting holes 5 on the module 2 that were originally used to be aligned with the mounting holes 5 of the packing box 3 and connected by bolts may be offset, and it will be difficult to accurately connect with the mounting holes 5 of the packing box 3 by bolts. The module 2 of this embodiment can be fixed to the packing box 3 by the bracket 1. The bracket 1 is made of a material with high hardness to prevent deformation, ensuring that it can be aligned with the mounting holes 5 of the packing box 3 for connection and fixation.

[0039] In addition, the module 2 was originally directly fixed to the packing box 3, which is usually a wooden box with low hardness. It is fixed in the packing box 3 by detachable connectors such as bolts. After a period of time, the bolt torque decays and becomes loose, which in turn causes the module 2 to easily vibrate and rub against the wooden box during handling or transportation. The module 2 of this embodiment is fixed to the packing box 3 by the bracket 1. The bracket 1 can use a sheet metal bracket 1 with high hardness to ensure that the bracket 1 and the module 2 can be stably hard-connected by bolts, reduce the torque and clamping force decay of the bolts, avoid loosening, and transfer the original loosening between the module 2 and the packing box 3 due to the low hardness of the packing box 3 to the bracket 1 and the packing box 3. In this way, the looseness, friction or bump between the original module 2 and the packing box 3 is transferred to the bracket 1 and the packing box 3, thereby improving the protection of the module 2.
