Description
Technical Field
[0001] The utility model relates to the technical field of vehicle accessories, in particular to a brake fluid storage pot cover. Background Art
[0002] The automobile brake oil reservoir is generally installed on the brake master cylinder to directly provide brake fluid to the brake master cylinder. Its main function is to seal the brake fluid, prevent brake fluid leakage, and prevent the risk of not being able to replenish the brake fluid in time when the car needs to replenish the brake fluid. However, the existing cover still has certain problems. The specific problems are as follows: When the braking deceleration is large, the liquid level floats greatly, and the brake fluid impacts the ventilation channel of the reservoir cover, the leakage is more serious, causing certain troubles to the user. In addition, the filter net inside the traditional cover is inconvenient to disassemble and clean, and long-term use is likely to reduce the filtering effect. The existing application number is CN202020645773.6, which is a kind of automobile brake oil reservoir cover, including a cover body, and the bottom of the cover body is clamped with an oil reservoir... The brake fluid can quickly enter the block, thereby reducing the liquid level height in the oil reservoir, and the floating plate can smooth the fluctuation of the brake fluid level, thereby preventing the brake fluid from leaking out and avoiding waste. However, the device installs the filter on the inner wall of the mouth of the oil reservoir. When disassembling and cleaning, it is necessary to remove the cover body first and then remove the filter, which is not convenient. In addition, the excess brake fluid produced when the liquid level rises is accommodated in the accommodating cavity on the inner wall of the mouth of the oil reservoir. Not only is the capacity too small, but it also increases the structural complexity and processing difficulty of the oil reservoir. Utility Model Content
