Description

Technical Field

[0001] The utility model relates to the technical field of battery module transportation, in particular to a fixing structure for a battery module. Background Art

[0002] A battery module is a unit assembled from multiple cells to provide higher voltage and capacity. It is a component in a battery system and is usually composed of several cells, connectors, a battery management system, and a casing. The main function of a battery module is to connect multiple cells together to increase the voltage and energy storage capacity of the battery system. Existing battery modules are relatively long. After being installed in a battery box, they will vibrate during transportation, reducing safety during transportation and causing deficiencies. Utility Model Content

[0003] The purpose of the utility model is to solve the above technical problems and provide a fixing structure for a battery module.

[0004] The technical solution of the utility model: a fixing structure for a battery module, comprising at least one connecting member and a plurality of pressure strips and locking members, wherein the connecting member is connected to a box body in which the module is placed, and the pressure strip is connected to the connecting member through the locking member and fixed above the module.

[0005] Preferably, the locking member is detachably connected to the pressure strip and the connecting member respectively.

[0006] Preferably, the locking member is a bolt.

[0007] Preferably, the middle portion of one side of the pressure strip has a protrusion extending outward.

[0008] Preferably, the layering strip is an engineering plastic layering strip.

[0009] The beneficial effect of the utility model is that in the utility model, by arranging a fixing structure between the module and the box body, the strength of the module installed in the box body is greatly increased, thereby ensuring the safety of the battery pack during driving.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0015] Reference Figures 1 to 3 A fixing structure for a battery module includes at least one connector 10 and a plurality of pressure strips 2 and locking members 3. The connector 10 is connected to a box in which the module is placed, and the pressure strip 2 is connected and fixed to the top of the module through the locking member 3 and the connector 10. In the utility model, the connector 10 is fixed to the box in which the module is placed. After the battery module is placed in the box, the connector 10 is between the two modules, and the pressure strip 2 is placed above the module. The pressure strip 2 is connected and fixed to the top of the module through the locking member 3 and the connector 10 to prevent the battery module from vibrating up and down during transportation, thereby improving the strength of the module fixed in the box. An avoidance groove is provided on the integrated busbar of the battery module, and one side of the pressure strip 2 is placed in the avoidance groove. The integrated busbar is placed on the battery module, and the upper cover plate is bolted to the integrated busbar. The pressure strip 2 presses the integrated busbar, which facilitates the installation of the integrated busbar and the cover plate. Specifically, when a module is placed in the box, connectors 10 and pressure strips 2 are provided on both sides of the module to fix the single module.

[0016] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0017] In this embodiment, the locking member 3 is detachably connected to the pressure strip 2 and the connecting member 10, respectively, so as to facilitate installation and disassembly.

[0018] In this embodiment, the locking member 3 is a bolt, the connecting member 10 is in an "X" shape, a plurality of threaded sleeves are provided on the connecting member 10, a countersunk hole is provided on the pressure strip 2, and one end of the locking member 3 passes through the countersunk hole and is threadedly connected to the threaded sleeve.

[0019] In this embodiment, a protrusion 201 extending outward is provided in the middle of one side of the pressure strip 2. The pressure strip 2 is a thin plate. The locking member 3 passes through the protrusion 201, which can improve the stability of the connection of the pressure strip 2.

[0020] In this embodiment, the layer strip 2 is an engineering plastic layer strip.

[0021] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
