Description

Technical Field

[0001] This invention relates to the field of power lithium-ion battery technology, and in particular to a multifunctional portable battery pack. Background Technology

[0002] Lithium batteries are a widely used power source. They are typically made by combining multiple individual cells in series and parallel, depending on the voltage and capacity requirements of the load. Series connection increases the voltage, and parallel connection increases the capacity.

[0003] The use of individual cells is gradually shifting to modularization, assembling them into large-capacity battery packs, which are increasingly being applied to fields such as electric vehicles and energy storage. Existing battery packs cannot be easily assembled, which limits their practical application. At the same time, existing loading devices cannot quickly load and unload battery packs of different specifications. Summary of the Invention

[0004] The problem solved by this invention is to provide a multifunctional portable battery pack, which addresses the issue that existing battery packs cannot be easily assembled due to the gradual shift from single-cell use to modular assembly into large-capacity battery packs for use in electric vehicles and energy storage, thus limiting their practical application. Furthermore, existing loading devices cannot quickly load and unload battery packs of different specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional portable battery pack includes a housing, a top cover, and a battery module. The battery module is installed inside the housing, and the top cover is installed on the top of the housing.

[0007] The battery module includes several copper busbars and two fixed baffles. Cell supports are provided on opposite sides of the two copper busbars. Several cells are installed between the two cell supports. Several fixing screws are installed through the copper busbars. The two ends of the fixing screws are connected to the fixed baffles respectively, and the fixed baffles are connected to the bottom of the housing.

[0008] Preferably, the side wall of the enclosure is equipped with several handles, the bottom of the enclosure is equipped with self-locking casters, the outer side of the enclosure is provided with heat dissipation slots, and the outer side of the enclosure is equipped with an output port, a switch, a power display screen and a communication port, and the output port, switch, power display screen and communication port are all electrically connected to the battery module.

[0009] Preferably, the copper busbar has a core slot adapted to the battery cell, and the copper busbar has a plurality of rod slots adapted to the fixing screw. The fixing screw passes through the fixing baffle and is connected to the nut.

[0010] Preferably, the bottom wall inside the box is symmetrically provided with bottom grooves, and a slider is slidably installed in the bottom groove, with bolts passing through the fixing baffle and threadedly connected to the slider.

[0011] Preferably, a turntable is rotatably mounted on the bottom of the box, a plurality of first heat dissipation holes are opened on the bottom side of the box, and a plurality of second heat dissipation holes are opened on the turntable.

[0012] Preferably, a threaded rod is installed inside the bottom groove, and the threaded rod is threadedly connected to the slider. A first bevel tooth is installed at one end of the threaded rod, and a connecting shaft is installed in the bearing inside the housing, with a second bevel tooth meshing with the first bevel tooth at the bottom end of the connecting shaft.

[0013] Preferably, a fixed shaft is installed through the center of the turntable, and the fixed shaft is connected to the housing bearing. Both the fixed shaft and the connecting shaft are equipped with polygonal sockets.

[0014] Preferably, the specific operating steps of this battery pack are as follows:

[0015] The battery cells are installed between the cell supports of the copper busbar. Then, a fixing screw passes through the rod groove of the copper busbar, with both ends of the fixing screw passing through a fixing baffle and connected to a nut. At this time, rotating the multi-sided socket drives the threaded rod to rotate, which in turn drives the threaded slider to move in the bottom groove. The positions of the two sliders are adjusted to correspond with the fixing baffle. Then, bolts pass through the fixing baffle and are threadedly connected to the sliders to fix the box and the battery module. The multi-sided socket drives the fixing shaft to rotate, which in turn drives the turntable to rotate. When the second heat dissipation hole of the turntable corresponds to the first heat dissipation hole, the bottom of the battery module is cooled through the first and second heat dissipation holes. When the first and second heat dissipation holes are misaligned, the bottom of the box is sealed.

[0016] The beneficial effects of this invention are: the battery cell is installed between the battery cell brackets of the copper busbar, and then a fixing screw passes through the rod groove of the copper busbar, and the two ends of the fixing screw pass through the fixing baffle and are connected to the nut respectively, which effectively protects the battery cell and fixes the battery cell, so that it can perform its due performance in harsh environments. It is very convenient in the assembly process, and the battery cells can be combined into battery modules of different specifications in the corresponding way.

[0017] At the same time, by rotating the multi-sided socket, the threaded rod is rotated, which in turn moves the threaded slider in the bottom groove. The positions of the two sliders are adjusted to correspond with the fixed baffle. Then, the fixed baffle is threadedly connected to the slider by bolts, so as to realize the installation of battery modules and boxes of the same specifications.

[0018] The fixed shaft is rotated by the multi-sided socket, which in turn drives the turntable to rotate. When the second heat dissipation hole of the turntable corresponds to the first heat dissipation hole, the bottom of the battery module is cooled through the first and second heat dissipation holes to improve the heat dissipation efficiency. When the first and second heat dissipation holes are misaligned, the bottom of the box is sealed. Attached Figure Description
