Description

Technical Field

[0001] The utility model belongs to the technical field of battery modules, and in particular relates to a battery module that is convenient for quick fixation and assembly. Background Art

[0002] At present, the battery module assembly methods on the market include stacking the upper module and the lower module, bundling the upper module and the lower module with electrical fiber tape to achieve a fixed structure, and connecting the upper module and the lower module in series by welding with wires. However, this module fixing method is not reliable, the conductive operation of the upper and lower modules in series is inconvenient, and the overall appearance of the module is not good. After searching, it was found that the application number "202022026018.2" discloses "a bolt for battery module stacking and a battery module stacking structure thereof", in which the upper battery module is directly mounted on the lower bolt through the design of the series bolt. This reduces the need for additional fixing brackets, simplifies the installation of battery modules in the battery box, and reduces the overall weight of the battery pack. However, the above-mentioned stacked and fixed battery modules still have certain shortcomings when in use: when installing the above-mentioned battery modules, the first bolts need to be installed first, and then the battery modules need to be stacked and fixed. This process is relatively cumbersome, and it is difficult to ensure that the top planes of the four first bolts at the corners are on the same horizontal plane when installing the first bolts, so there is a hidden danger of uneven installation when stacking the battery modules. Based on this, we propose a battery module that can quickly fix components. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 2 The utility model provides the following technical solutions: a method for quickly fixing and assembling a battery module, comprising two battery modules to be assembled, an epoxy plate 1 being provided between the two battery modules and the two battery modules being fixed by screws 2.

[0019] In this embodiment, the battery module includes a mounting plate 3, on the surface of which a number of battery cells 4 are evenly and equidistantly arranged, a PCB board 5 is installed on the top of the battery cells 4, the PCB board 5 is electrically connected to the battery cells 4, a copper stud 6 is soldered and installed on the side edge of the surface of the PCB board 5, an opening 7 connected to the copper stud 6 is opened at the bottom end of the PCB board 5, and a screw 2 is threadedly connected to the two copper studs 6 through the opening 7 to fix the two battery modules.

[0020] Specifically, when fixing two battery modules, the copper studs 6 are aligned by stacking the two battery modules, and the screws 2 are passed through the openings 7 and threadedly connected to the corresponding copper studs 6, thereby completing the fixed assembly of the battery modules. The copper studs 6 have good conductivity, so the two battery modules can be connected. The copper studs 6 soldered to the surface of the PCB board 5 have uniform specifications, so there will be no unevenness when the battery modules are stacked and installed.

[0021] In this embodiment, a plurality of recesses 8 are provided on the side of the epoxy board 1 to match the positions of the copper studs 6 .

[0022] Specifically, the epoxy plate 1 has good insulation properties, thereby preventing short circuits from occurring when two battery modules are stacked, and the provision of the relief grooves 8 facilitates quick fixation and assembly of the two stacked battery modules.

[0023] In this embodiment, a supporting column 9 is further installed on the surface of the PCB board 5 .

[0024] Specifically, by setting the top support column 9, when the two battery modules are stacked and installed, the epoxy board 1 is clamped by the top support column 9 in the two battery modules, thereby preventing the epoxy board 1 from directly contacting the PCB board 5 and causing damage to the PCB board 5. In addition, there is a gap between the epoxy board 1 and the PCB board 5 to facilitate heat dissipation of the PCB board 5.

[0025] In this embodiment, the height of the top support column 9 is smaller than the height of the copper stud 6 , and when two battery modules are stacked, the top support columns 9 in both battery modules contact the epoxy board 1 .

[0026] Specifically, this method allows the epoxy plate 1 to be fixed while the battery modules are stacked and installed.

[0027] In this embodiment, the supporting column 9 is a rubber column.

[0028] Specifically, since the supporting column 9 is a rubber column, it has a certain deformation ability, and can better clamp and fix the epoxy board 1.

[0029] Working principle: When fixing and assembling the battery modules, first lay one of the battery modules flat and place the epoxy plate 1 on the surface, then stack the other battery module on top of the epoxy plate 1, and align the copper studs 6 in the two battery modules through the provided recesses 8 and connect them by screws 2, so that the two battery modules can be quickly fixed. Since the copper studs 6 have good conductivity, they can not only fix the battery modules but also connect the battery modules to ensure conductivity. And since the specifications of the copper studs 6 match, the stacked battery modules will not be uneven.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
