Description

Technical Field

[0001] The utility model belongs to the technical field of battery shell design, and specifically relates to a lithium battery and electronic component combined waterproof shell. Background Art

[0002] Lithium battery refers to a battery containing lithium in the electrochemical system, including metallic lithium, lithium alloy, lithium ion, and lithium polymer. With the explosive development of smart phones and tablet computers, lithium battery technology is also constantly innovating. Compared with traditional lead-acid batteries, lithium batteries have the advantages of small size, light weight, and less environmental pollution. Thanks to the above advantages, lithium batteries are gradually replacing lead-acid batteries in the electric vehicle industry, UPS and energy storage power station industry and becoming the mainstream.

[0003] At present, when traditional lithium batteries are used in combination in series or in parallel, it is necessary to manually use wires to connect the positive and negative electrodes of the lithium batteries that need to be used in combination. Manually using wires in series to connect lithium batteries requires wrapping and sealing the locations where the wires are connected. In addition, in addition to the wires, some components need to be assembled on the battery. Therefore, the battery compartment and components need to be waterproofed separately, which is very inconvenient.

[0004] In order to solve the above problems, the Chinese utility model patent with application number CN202321674845.X discloses a battery and capacitor combined integral waterproof injection molded plastic shell, including an injection molded shell, the outside of the injection molded shell is provided with a waterproof plastic shell of the same shape, the inside of the injection molded shell is provided with a battery compartment and a capacitor compartment, the battery and the capacitor are placed respectively, the capacitor compartment is arranged on the side of the battery compartment, the capacitor compartment and the top height of the battery compartment are the same, the overall height of the battery compartment is greater than the overall height of the capacitor compartment, the side wall of the battery compartment is connected with the side wall of the capacitor compartment, the top edge of the capacitor compartment is provided with a lead groove, the negative electrode connecting plate track extends from the bottom inner wall of the capacitor compartment to the side inner wall of the battery compartment, and a bottom positioning column is provided at the bottom of the battery compartment. This solution solves the complex process of waterproofing and reassembling the battery compartment and capacitor compartment monomers one by one in the traditional process. However, since this solution only involves the assembly of a single battery and capacitor, in the actual production of lithium batteries, most of the time, two batteries are connected in parallel or in series and then waterproofed and assembled as a whole. At this time, the structure of the above solution is no longer applicable. Therefore, there is an urgent need for a combined waterproof shell suitable for dual lithium batteries, leads and electronic components to solve the above problem. Utility Model Content

The internal series-parallel wires of the battery pack are placed in the series-parallel connecting wire track, and are integrated with the shell when the sealant is poured. The external wires are fixed in the lead groove, which makes the overall appearance beautiful and improves the safe use of the electronic components.

[0006] The technical solution adopted by the utility model is: a lithium battery and electronic component combined waterproof shell, including an outer shell with an opening on the top, the interior of the outer shell is provided with two battery compartments designed side by side and connected to each other, the inner walls of the two battery compartments are provided with accommodating grooves for accommodating leads and components, and the two accommodating grooves are staggered on the outer shell.
