Abstract
The utility model discloses a brake alarming device of vehicle. The brake alarming device of vehicle scarcely changes any components of existing vehicle brakes, improves a reservoir compartment, changes the reservoir compartment to a dual chamber connection reservoir compartment, wherein, one chamber stores oil, and a floating drum is arranged in the other chamber, a magnetic steel is arranged on the floating drum, and a hall element is arranged at the relevant position of the chamber corresponding to the magnetic steel, which forms a magnetic contactless switch. The utility model has the advantages of artful design and simple structure, can effectively anticipate warning to brake accidents, and fundamentally solves the problems of the reliability and safety of the vehicle brakes.
Description
The utility model relates to a kind of warning device, particularly automobile brake alarming device.
Present automobile braking device is made up of reservoir compartment, master cylinder, oil pipe, wheel cylinder, and the brake solution of reservoir compartment is communicated with the master cylinder brake solution, and master cylinder promotion piston makes brake solution enter wheel cylinder through oil pipe during brake, struts wheelcylinder piston and realizes brake.When oil pipe when leakage of oil appears in loosening or pipe break because of joint, master cylinder will enter air, makes brake failure.Solve the problem of brake leakage of oil at present on some senior cars by use double-piston double pump, i.e. during one of them pump leakage of oil, another pump is normal operation still, with the assurance brake, but this scheme is a kind of passive scheme, does not tackle the problem at its root, and parts increase, and cost rises.
The purpose of this utility model is exactly in order fundamentally to address the above problem, and a kind of early-warning device for braking automobile is provided, and it can be reported to the police to the braking automobile oil leakage fault in advance.
Technical solution of the present utility model:
A kind of early-warning device for braking automobile, the reservoir compartment that it will have automobile now changes two-chamber connection reservoir compartment 1 into, automotive brake fluid is gone in storage in one of them cavity 2, the lower end outlet of this cavity 2 directly is communicated with the automobile brake general pump oil circuit by nut 3, it is characterized in that having little air gate 5 on the upper end fuel door 4 of this cavity 2, in another cavity 6 of two-chamber connection reservoir compartment 1, be placed with floating drum 7, floating drum 7 is provided with magnet steel 8, to should on the relevant position of cavity 6, being provided with Hall element 9 by magnet steel 8, constitute the magnetic noncontacting switch.
The utility model design is ingenious, simple in structure, changes the brake part of existing automobile hardly, only the reservoir compartment is improved, and just can report to the police in advance to the brake fault effectively, has fundamentally solved the reliability and the safety issue of braking automobile.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
As Fig. 1, two-chamber is communicated with the cavity 6 interior floating drums 7 of reservoir compartment 1 and makes for light material, it can be cylindric, and also flat column also can be other shape, if floating drum 7 is cylindric, magnet steel 8 is located at its upper and lower surface, if floating drum 7 is a flat column, magnet steel 8 can be located at its upper and lower surface or any side, when just magnet steel 8 is contained in a side of flat column floating drum 7, should keep floating drum 7 balances.Two-chamber is communicated with also can adopt other magnetic switch element with magnet steel 8 cooresponding Hall elements 9 on reservoir compartment's 1 cavity 6, as the steel spring pipe etc.The outside face that is communicated with reservoir compartment's 1 cavity 6 at two-chamber is provided with Hall element socket box 10, and Hall element or other magnetic switch element are housed in it, and Hall element socket box 10 is connected by the interior warning circuit of plug 11 and operator's compartment.Warning circuit such as Fig. 2, it is by transistor T

3The switch circuit of forming.During the utility model work, two-chamber is communicated with two cavitys 2,6 of reservoir compartment 1 and all fills with automotive brake fluid, utilize the gravity of oil and the buoyancy of floating drum 7 that floating drum 7 is floated, magnet steel 8 on the floating drum 7 is just in time near the Hall element 9 in the Hall element socket box 10 on the cavity 6, so transistor T in the warning circuit
1Conducting, green light-emitting diode D
1Bright, expression automotive brake fluid oil level is normal.When automobile brake system oil pipe generation leakage of oil, brake solution in the cavity 2 can reduce, when reducing to a certain degree (this moment, brake system was not malfunctioning), the gravity of the buoyancy of the floating drum 7 in the cavity 6 and oil all reduces, floating drum 7 is descended, magnet steel 8 on the floating drum 7 is away from Hall element 9, then transistor T
1End, electric current passes through resistance R
3Make transistor T
2Conducting, Red LED1 D
2Bright, buzzer phone Y sounds, and acousto-optic is reported to the police simultaneously, shows automobile brake system oil level mal, need carry out trouble tracing, up to trouble removal, plays the effect of reporting to the police in advance, and accident potential is eliminated among bud.The magnetic noncontacting switch of being made up of magnet steel 8 and Hall element 9 in the utility model can be operated in Chang Gao or often low state (or normal open normal off state), and warning circuit conversion with it gets final product.
The utility model also can directly be provided with the airtight cavity that a through hole is arranged at a bottom on the bottom surface of the reservoir compartment's fuel door 4 that has automobile brake system now, be placed with floating drum 7 in this airtight cavity, floating drum 7 still is connected with warning circuit by the magnetic noncontacting switch, when fuel door 4 directly is rotated with in the reservoir compartment at automobile brake system, this reservoir compartment constitutes two-chamber with the airtight cavity of fuel door 4 and is communicated with the reservoir compartment, finishes brake pre-alarm function.
In addition, also floating drum 7 directly can be placed in the reservoir compartment of existing automobile brake system, and be provided with guiding mechanism in the reservoir compartment,, can finish brake pre-alarm function equally to guarantee floating drum 7 directed upper and lower floating.
