Description

Technical Field

[0001] The utility model belongs to the technical field related to solar cells, and specifically relates to a waterproof battery for solar street lamps. Background Art

[0002] Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-controlled sealed batteries to store electricity, and ultra-bright LED lamps as light sources. They are controlled by intelligent charge and discharge controllers to replace traditional public electric lighting street lights. They do not require laying cables, AC power supply, or electricity bills. They have good stability and long life and are widely used in various places. The batteries used in street lights are usually lithium batteries. In order to extend the service life of the batteries, special protective shells are required for protection. Solar street lights are outdoors for a long time, facing the use environment of wind, sun, and rain. The waterproof sealing effect of traditional battery structures is not ideal. The gaps in the shell and the connection of the lines will cause the battery box to fail to achieve the expected dust and water proof effects. In addition, the functions of the battery box are relatively single. During the carrying and installation process, the lack of protective measures can easily cause the battery to collide inside the box and cause damage, seriously affecting the subsequent use of the battery.

[0003] In view of this, the present utility model is proposed. Utility Model Content
