[0002] Electric motorcycle batteries usually refer to batteries used in electric vehicles (EVs) or electric motorcycles (e-bikes). The battery of an electric vehicle is the core component that provides power and ensures the normal operation of the vehicle; common types of electric motorcycle batteries include lithium-ion batteries, lead-acid batteries, and nickel-metal hydride batteries.

[0003] During the charging of batteries, especially lead-acid batteries, hydrogen and oxygen may be generated inside the battery. If the gas cannot be discharged, it may cause the internal pressure of the battery to increase, affecting the performance and life of the battery; gas accumulation may also increase the degree of corrosion inside the battery, thereby affecting the battery structure and electrochemical reaction; although lead-acid batteries are designed with exhaust valves, the valve will carry some acid during the exhaust process, and the bumps of the vehicle can easily cause the acid in the battery to seep out when the valve is exhausted, causing corrosion to other external components. Utility Model Content

[0004] The utility model aims to solve the problem that the acid of the lead-acid battery is easily discharged and seeped out along with the gas during the exhaust process of the lead-acid battery, and provides an electric locomotive battery charging exhaust device, which can prevent the acid of the battery from being discharged while exhausting the gas.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] The camshaft is an axially axially axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery, wherein the camshaft is an axially axially axially traversing the outer wall of the battery

[0026] The rotating plate 8 is a circular ring with an outer diameter equal to that of the outer cylinder 2. The inner ring of the rotating plate 8 is fixedly connected to the upper end of the peripheral wall of the rotating rod 7, and the bottom surface slides in contact with the outer top surface of the outer cylinder 2; the air hole 19 is an arc-shaped hole penetrating the closed end of the outer cylinder 2; multiple air holes 19 are on the same circular ring, the air hole 2 10 is an arc-shaped hole penetrating the upper and lower sides of the rotating plate 8, and multiple air holes 2 10 are on the same circular ring.

[0027] The driving ring 11 is a circular ring body, the outer ring surface of the driving ring 11 is in sliding contact with the inner wall of the inner cylinder 3, and the inner ring surface is in contact with the peripheral wall of the rotating rod 7. An inclined groove 13 is provided on the peripheral wall of the rotating rod 7 in the inner cylinder 3. A driving block 14 is fixed on the inner wall of the driving ring 11.

[0028] A limiting ring 20 is fixed at the lower end of the inner wall of the inner cylinder 3. The limiting ring 20 is a circular ring body whose outer ring is fixedly connected to the inner wall of the inner cylinder 3. When the spring 12 is in a natural state, the driving ring 11 contacts the limiting ring 20.

[0030] When in use, when the battery body 1 is not working, the spring 12 is in a natural state, the driving ring 11 contacts the limiting ring 20, and each air hole 10 and the adjacent air hole 1 9 are in a dislocated state; the valve is in a sealed state, which can prevent external dust from entering the battery body 1 through the air hole 10 and the air hole 1 9;

[0031] When the battery body 1 is working, gas is generated, and the gas presses the driving ring 11 upward, and the driving ring 11 moves upward, and the spring 12 is compressed. When the driving ring 11 moves upward, the air in the inner cylinder on the upper side of the driving ring can be discharged through the through hole 2 and the through hole 1, and the driving block 14 on the driving ring 11 presses the inclined groove 13, so that the rotating rod 7 drives the rotating plate 8 to rotate.

After the small droplets of acid on the guide tube 1 5 and the guide tube 2 6 accumulate, they will form large droplets, flow downward along the peripheral wall of the guide tube 1 5 and the guide tube 2 6, and flow back into the battery body 1; and in the process of vehicle bumping, the acid in the battery body 1 will be blocked by the guide tube 1 5 and the guide tube 2 6 between the outer tube 2 and the inner tube 3 during the bumping process, thereby shortening the upward movement of the bumped acid, avoiding the acid from seeping out through the pores 1 and pores 2 due to the bumping of the vehicle during the valve exhaust process, so that the acid that enters between the outer tube 2 and the inner tube 3 due to the bumping of the vehicle will flow back into the battery body 1;

[0032] When the gas is insufficient to move the driving ring 11 upward, the restoring force of the spring 12 drives the driving ring 11 to move downward back to the initial state, and the driving ring 11 drives the rotating rod 7 to drive the rotating plate 8 back to the initial state, and the valve is closed and sealed again.
