Technical Field
[0001] The utility model relates to the technical field of automobile brake oil pot liquid level monitoring, in particular to an oil pot liquid level sensor. Background Art
[0002] The car brake fluid tank, also known as the brake master cylinder or brake pump, is one of the important components for storing and delivering brake fluid. It is usually installed in the car engine compartment, near the brake pedal.
[0003] The main functions of the brake fluid tank include the following aspects:
[0004] 1. Brake fluid storage: The brake fluid tank stores the brake fluid used in the hydraulic brake system. The brake fluid plays a role in transmitting pressure and increasing braking force in the system.
[0005] 2. Hydraulic transmission: When the driver steps on the brake pedal, the brake fluid in the brake oil tank is pushed into the hydraulic pipeline of the brake system. This will generate hydraulic pressure, which will be transmitted to the brake pads or brake discs of the wheels through the hydraulic system, thereby achieving braking.
[0006] 3. Fluid level monitoring: The brake fluid tank is usually equipped with a fluid level sensor or a fluid level indicator to monitor the brake fluid level. This helps to check the consumption of the brake fluid in time and ensure that the system is in good condition.
[0007] 4. Prevent air from entering: The brake fluid tank is designed as a sealed structure to prevent air from entering the brake system. The presence of air may cause brake failure or poor brake feel.
[0008] The proper functioning of the brake fluid reservoir is essential to the vehicle's braking performance. Regularly checking the brake fluid level and quality, and ensuring the tightness and stability of the brake system can ensure safe driving and effective braking operation.
[0009] During the use of the automobile brake fluid tank, a liquid level sensor is required to monitor the liquid level. The existing liquid level sensor of the oil tank has a complex structure, often fails during use, and is cumbersome to repair, resulting in high cost of use, low monitoring accuracy, and complex operation, which is not conducive to people's use. No solution has been proposed for the relevant technical problems. Utility Model Content
