Description
Technical Field
The invention relates to a brake fluid storage tank in the technical field of automobile brake systems, in particular to an alarm device of an automobile brake fluid storage tank.
Background
The brake fluid storage tank is a key component in an automobile braking system, and mainly has the function of providing brake fluid for a brake master cylinder and a brake pipeline, so that the pressure of the brake fluid is converted into mechanical energy, and an automobile can generate braking force. Generally, the brake fluid sub-chambers are controlled by the partition plates in the liquid storage tank, and brake fluid is supplied to each chamber of the brake master cylinder and the clutch slave cylinder one by one, so that after one chamber fails, other chambers still have a braking function.
The main function of the brake fluid storage tank is to store brake fluid and provide and supplement brake fluid with enough energy for a brake system, so as to ensure the reliability of the automobile in the process of driving and braking, thereby ensuring that the amount of the stored brake fluid is safe, but the brake fluid is reduced due to some reasons in the using process, and safety accidents occur due to excessive reduction, so that the condition of reducing the stored brake fluid needs to be alarmed, but a related alarm device is absent at present, and hidden troubles are brought to the driving safety.
Disclosure of Invention
The invention provides an alarm device of an automobile brake fluid storage tank, which aims to solve the problem of potential safety hazard caused by the lack of a device for alarming the brake fluid reduction condition at present.
The technical scheme adopted by the invention is as follows: the tank body is internally provided with a float cavity, a float component is in sliding connection with the float cavity, a magnet is molded below the inside of the float component, an alarm component is fixedly connected to the outside of the tank body below the float component, and a reed pipe is welded inside the alarm component.
The float part is made of polypropylene materials.
When the float component is positioned at the upper part of the float cavity, the middle reed of the reed pipe is not magnetized by the magnet and is in a disconnected state.
When the floater part is positioned at the lower part of the floater cavity, the middle reed of the reed pipe is in an attraction state after being magnetized by the magnet.
The invention has the advantages of novel structure, and when the liquid level of the stored brake fluid drops to a certain position, the reed pipe is magnetized by the magnet, so that the reed in the reed pipe is changed in a switching way, an alarm circuit of the whole vehicle is driven, the aim of warning an operator is fulfilled, the driving safety of the vehicle is ensured, the number of added parts is small, the cost is low, and the operation is easy.

FIG. 2 is a schematic view of the float member of the present invention at a high level;
FIG. 3 is a view of the reed switch in an open position with the magnet of the present invention away from the reed switch;
FIG. 4 is a schematic view of the float assembly of the present invention as it drops to an alarm level;
fig. 5 is a view showing a state where the reed pipe is magnetized and connected when the magnet of the present invention is close to the reed pipe.
Detailed Description
As shown in fig. 1, a float cavity 201 is arranged in a tank body 2, a float component 1 is slidably connected with the float cavity 201, a magnet 4 is molded below the inner part of the float component 1, an alarm component 3 is fixedly connected to the outer part of the tank body 2 below the float component 1, and a reed pipe 5 is welded inside the alarm component 3.
The float part 1 is made of polypropylene material.
When the float member 1 is positioned above the float cavity 201, the middle reed 501 of the reed pipe 5 is not magnetized by the magnet 4, and is in an off state.
When the float component 1 is positioned at the lower part of the float cavity 201, the middle reed 501 of the reed pipe 5 is magnetized by the magnet 4 and then is in an attraction state.
Principle of operation
As shown in fig. 2, when the brake fluid level a in the reservoir is high, the foaming agent is added into the polypropylene material of the float component 1, so that the density of the float component is less than that of the brake fluid, the float component 1 moves up and down in the brake fluid through buoyancy, and the float component 1 is far away from the alarm component 3 through buoyancy, as shown in fig. 3, at this time, the magnet 4 in the float component 1 cannot sense the reed pipe 5 in the alarm component 3, and the reed 501 in the reed pipe 5 is not magnetized and is in a disconnected state, so that the alarm line of the whole vehicle is in a disconnected state;
as shown in fig. 4, when the brake fluid level B in the reservoir gradually drops, the float member 1 gradually approaches the alarm member 3 by buoyancy, and when the float member 1 drops to a certain position, as shown in fig. 5, the magnet in the float member 1 starts to sense the reed pipe 5 in the alarm member 3, and the reed 501 in the reed pipe is magnetized and in an attraction state, so that the alarm line of the entire vehicle is in a connection state, thereby starting to alarm.
