Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection end covers, and more specifically, to an electrical connection end cover of a bicycle lithium battery. Background Art

[0002] Lithium battery electric bicycles refer to electric bicycles that use lithium batteries as auxiliary energy sources. They are mechatronic personal transportation vehicles equipped with motors, controllers, batteries, control components such as throttles and brakes, and display instrument systems. After installation, a large part of the lithium battery of electric bicycles in the prior art will be exposed to the outside world. When it rains or encounters water sources, water can easily enter the plug-in port, so a shell needs to be installed for protection. However, adding a protective shell to the position of the plug-in port directly has a poor protective effect on the lithium battery of electric bicycles. Not only is it easy to be damaged after a collision and cause secondary damage to the internal lithium battery, but the gaps in use may also allow water to leak in, resulting in poor use effect.
