Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive braking system technology, specifically brake fluid reservoirs, and particularly relates to a reverse alarm automotive brake fluid reservoir. Background Technology
[0002] The brake fluid reservoir is a key component of the automotive braking system, with two main functions: first, to store brake fluid and provide it to the hydraulic braking system; and second, to illuminate a warning light on the dashboard when the brake fluid is low, reminding the driver to add brake fluid.
[0003] Regarding the warning function, the vehicle's circuitry typically consists of two types: a forward circuit and a reverse circuit. The forward circuit is activated when the liquid level is high, at which point the warning light inside the vehicle is off. When the liquid level drops, the circuit is activated, and the vehicle displays a low liquid level warning light. The reverse circuit is activated when the liquid level is high, at which point the warning light inside the vehicle is off. When the liquid level drops, the circuit is activated, and the vehicle displays a low liquid level warning light.
[0004] In the whole vehicle, the design of the brake fluid reservoir with reverse alarm is more difficult and the manufacturing and quality costs are higher, so the reverse circuit is used less often. However, the use of the reverse circuit can eliminate the fault of the fluid level sensor itself, reducing the probability of false alarm or no alarm in the whole vehicle. Therefore, the use of the reverse circuit is beneficial. Thus, it is necessary to develop a brake fluid reservoir with reverse alarm that can reduce design difficulty and manufacturing cost. Summary of the Invention
[0005] This invention provides a brake fluid reservoir with reverse alarm function to solve the problems of high design difficulty and high manufacturing cost of current reverse alarm brake fluid reservoirs.
[0006] The technical solution adopted by this utility model is as follows: it includes a liquid storage tank, a float, a liquid level sensor and a magnet, wherein the liquid level sensor is fixedly connected to the upper part of the liquid storage tank, the float is located in the guide groove inside the liquid storage tank, the magnet is installed on the upper part of the float, and the liquid level sensor and the float are on the same axis.
[0007] The float is buoyed by the brake fluid in the reservoir. When the brake fluid level makes the magnetic force of the magnet in the float fall within the working range of the level sensor, the internal circuit is connected and the vehicle warning light does not illuminate.
[0008] When the brake fluid level causes the magnetic force of the magnet in the float to fall outside the working range of the level sensor, the internal circuit is disconnected, and the vehicle's warning light illuminates.
[0009] The liquid level sensor is detachably assembled with the liquid storage tank.
[0010] The advantages of this utility model are its novel structure, minimal modification to existing structures, few new parts, and ability to achieve reverse alarm. The assembly structure of each part is simple and easy to operate, reducing design difficulty and manufacturing costs. Attached Figure Description
[0011] Figure 1 This is a structural schematic diagram of the present invention, showing the normal usage state.
[0012] Figure 2 This is a state diagram of the alarm state of this utility model. Detailed Implementation
[0013] like Figure 1 , 2 As shown: It includes a storage tank 1, a float 2, a level sensor 3 and a magnet 4. The level sensor 3 is fixedly connected to the upper part of the storage tank 1. The float 2 is located in the guide groove 101 inside the storage tank 1. The magnet 4 is installed on the upper part of the float 2. The level sensor 3 and the float 2 are on the same axis.
[0014] The float 2 is buoyed by the brake fluid in the reservoir 1. When the brake fluid level makes the magnetic force of the magnet 4 in the float 2 fall within the working range of the level sensor 3, the internal circuit is connected and the vehicle warning light does not illuminate.
[0015] When the brake fluid level causes the magnetic force range of the magnet 4 in the float 2 to be outside the working range of the level sensor 3, its internal circuit is disconnected, and the vehicle's warning light illuminates.
[0016] The liquid level sensor 3 and the liquid storage tank 1 are assembled in a detachable manner.
[0017] Working principle:
[0018] like Figure 1 As shown, the brake fluid is at full level. The float 2 approaches the level sensor 3 under the buoyancy of the brake fluid. At this time, the magnet 4 inside the float approaches the level sensor 3, which connects the circuit of the level sensor 3, and the warning light inside the vehicle does not light up.
[0019] like Figure 2 As shown, when the liquid level is low, the float 2 moves away from the liquid level sensor 3 under the action of the buoyancy of the brake fluid, and the magnet 4 inside the float moves away from the liquid level sensor 3. At this time, the circuit of the liquid level sensor 3 is disconnected, and the warning light inside the vehicle illuminates.
