Electric bicycle battery with good waterproof sealing structure

Abstract

The invention belongs to the technical field of batteries, and discloses an electric bicycle battery with a good waterproof sealing structure, the electric bicycle battery comprises a shell, the top of the shell is movably provided with a top shell, the top of the inner surface of the shell is fixedly provided with an expansion sponge, and the interior of the shell is fixedly provided with a fixing rod located at the bottom end of the expansion sponge. By arranging the expansion sponge, the first air bag and the second air bag, due to the fact that the expansion sponge expands after absorbing a water source, the first air bag in the expansion sponge is extruded, and compared with a traditional structure, the device can rapidly act on the water source by means of the water absorption expansion characteristic of the expansion sponge; the first water source is prevented from entering the interior of the shell before the expansion sponge expands, and the expansion sponge has a certain blocking effect on the water source after expansion, so that the sealing effect is better.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to an electric bicycle battery with a good waterproof sealing structure. Background technique [0002] A battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery and belongs to secondary batteries. The working principle of the battery is to use external electrical energy to regenerate the internal active material when charging, store the electrical energy as chemical energy, and convert the chemical energy into electrical energy again when it needs to be discharged. [0003] At present, the electric bicycle batteries generally used in the market are usually placed directly under the seat cushion. In order to make the electric bicycle more concise and save the production cost, the electric bicycl...

AI Technical Summary

Problems solved by technology

[0003] At present, the batteries of electric bicycles generally used on the market are usually placed directly under the seat cushion. In order to make the electric bicycle more concise and save production costs, the battery of the electric bicycle is directly exposed to the outside world. The sealing structure is relatively simple, which makes it easy for rainwater to enter the battery of the electric bicycle, which may cause power failure of the electric bicycle, or lead to short-circuit damage to the battery, which increases the workload and maintenance costs of maintenance personnel, and reduces the user experience.

[0004] Ordinary electric bicycle batteries are directly exposed to the outside world, making rainwater and other liquids easily enter the interior of the electric bicycle battery through the gaps in the cover of the electric bicycle battery, and accumulate and accumulate inside, because the accumulated rainwater cannot be discharged to the outside world, making rainwater and After a long time of contact, the electric bicycle battery will cause corrosion to the electric bicycle battery, thereby reducing the service life of the electric bicycle battery, so it needs to be improved and optimized

[0005] The charging port on the surface of the general electric bicycle battery is directly installed on the surface of the electric bicycle battery. Since the existing protective structure directly adopts a buckle to be stuck at the charging port, when the electric bicycle is prone to bumps during walking, the card will be stuck. The buckle is detached and lost, which makes it impossible to protect the charging port for a long time, which is not convenient for the staff to use, and accelerates the wear rate of the charging port, which needs to be improved
