The utility model has the advantages of having simple structure, facilitating installation, clearly reminding the speed of the brake, decreasing the accident and overcoming the problems of oil leakage for the oil way of the brake.
Description
Technical field
The utility model relates to a kind of general vehicle illumination or signalling apparatus, relates in particular to a kind of device that is used to indicate brake action.
Background technology
At present, most employed stoplight stop lamps of vehicle, mostly rearward vehicle shows that this car brakes, how can not demonstrate this car and be the normal braking or the dynamics of emergency brake and brake, the vehicle drivers at rear can not accurately be judged the braking state of front vehicles rapidly, can only light and the distance of two cars is made brake and judged according to the stoplight stop lamp of front vehicles, be easy to cause the rear-end collision of vehicle.In the brake process, driver's pin touches on the brake the pressure of pedal when varying in size, varying in size of pedal displacement, pressure size in oil pump or the oil pipe is also different, the displacement size of oil cylinder inner carrier is also different, the pressure that passes to brake facing is also different, the speed of brake is just different, utilize sensing element to predict the variation of these parameters in the brake process in the prior art, and be converted into electric signal, pass to stoplight stop lamp again, make stoplight stop lamp send the optical signal of different brightness, thereby can point out the speed of braking automobile clearly.
Chinese patent as Granted publication on the 4th August in 2004, notification number is CN2630041Y, it discloses a kind of brake of motor-driven vehicle degree caution system, collected and information subregion two parts constitute by the brake deceleration information of different mode and degree, its information collection component divides by the speed relay that is fixed in the spacing relay before the Das Gaspedal bar and be connected in parallel in three pressure switches on the brake fluid line pipe and be parallel to speed meter and constitutes.Solve existing brake of motor-driven vehicle lamp and only identified brake and the pattern and the degree of brake deceleration can't be conveyed to back retinue vehicle clearly, thereby be easy to produce the problem that knocks into the back.But in the device of this kind structure,, not only destroyed the integrative-structure of brake fluid line pipe because pressure switch need be arranged in the brake fluid line pipe, and if seal bad meeting and cause the leakage of oil of brake fluid line pipe, braking quality is affected.
The utility model content
The objective of the invention is to overcome above-mentioned defective, a kind of later-model braking automobile dynamics indicating device is provided, it can not destroy the integraty of brake fluid line pipe, and has the effect of good indication braking strength.
For reaching above-mentioned effect, the utility model adopts following technical scheme: it comprises the brake pump housing, brake fluid line pipe, pressure sensor, the pump housing that wherein brakes comprises that total oil pump of brake and brake divide oil pump, and pressure sensor is arranged on the total oil pump of brake or/and brake divides on the oil pump.
Pressure sensor is connected by the bolt mode is airtight with the brake pump housing, and the pump housing that so both can prevent to brake, can be convenient to again change when pressure sensor damages owing to seal bad oil impregnate outward in the pressure sensor junction.Partly or entirely on the brake branch oil pump pressure sensor is set, usually all be provided with a total oil pump of brake and four brake branch oil pumps on the existing automobile, pressure sensor can only be arranged on the total oil pump of brake or brake divides on the oil pump, also can divide on the oil pump all be provided with, and pressure sensor can only be arranged on and also can be arranged on a plurality of brakes on the brake branch oil pump and divide on the oil pump in the total oil pump of brake and brake.Be arranged on brake and divide the pressure sensor on the oil pump to be provided with exhaust bolt, the inner chamber of exhaust bolt divides the oil pump inner chamber to connect by pressure sensor and brake.
Driver's pin pedal that touches on the brake in the brake process, when the pressure of brake pedal varies in size, the pressure that causes braking in the pump housing and the brake fluid line pipe varies in size, the displacement of oil cylinder inner carrier varies in size, the pressure that passes to brake facing is also different, the speed of brake is just different, utilize pressure sensor to predict the variation of these parameters in the brake process, and it is converted to electric signal by signal switching processor, again electric signal is passed to stoplight stop lamp, make stoplight stop lamp send the optical signal of different brightness, thus the speed of display automobile brake clearly.Stoplight stop lamp is to reach the purpose that shows different brake speeds, should select can clear and definite brightness lamp.But under the daylight, the variation of stoplight stop lamp brightness is difficult for difference, preferably selects the stoplight stop lamp group for use by day, distinguishes by the brightness realization of stoplight stop lamp group different piece lamp.
The utility model is simple in structure, is convenient to install, and can point out the speed of braking automobile clearly, thereby reduce the generation of accident, and overcome the problem of brake fluid line pipe leakage of oil.

Fig. 2 is the combination scheme drawing of the brake pump housing of the present utility model and pressure sensor;
Fig. 3 is the combination scheme drawing of total oil pump of brake and pressure sensor;
Fig. 4 divides the combination scheme drawing of oil pump and pressure sensor for brake.
The specific embodiment
This device comprises the brake pump housing 1, brake fluid line pipe 2, pressure sensor 4, the pump housing 1 that wherein brakes comprises that the total oil pump 11 of brake divides oil pump 12 with brake, pressure sensor 4 is arranged on the total oil pump 11 of brake and all brakes divide on the oil pump 12, be arranged on brake and divide the pressure sensor 4 on the oil pump 12 to be provided with exhaust bolt 5, the inner chamber of exhaust bolt 5 divides oil pump 12 inner chambers to connect by pressure sensor 4 and brake.
During brake, the driver steps on brake pedal 2, and the oil in the brake fluid line pipe 2 is compressed, and oil pressure raises, and pressure is delivered in the brake pump housing 1 by brake fluid line pipe 2, promotes piston rod 3 and moves, and piston rod 3 reaches the purpose of brake with the brake facing locking of automobile.
Because dividing on the oil pump 12, total oil pump 11 of brake and brake all be provided with pressure sensor 4, but perception in-to-in oil pressure, pressure sensor 4 is exported to signal switching processor with detected oil pressure numerical value, signal switching processor converts the pressure signal that receives to digital signal, and be transferred to the electroluminescent lamp group, thereby can reach the purpose of the bright dark degree of control lamp according to the power of brake pedal 2 pressure signals to converting electric signal after the digital signal processing to.
Be that with the difference of embodiment 1 pressure sensor 4 is arranged on the total oil pump 11 of brake and the part brake divides on the oil pump 12.
Be that with the difference of embodiment 1 pressure sensor 4 is arranged on the total oil pump 11 of brake or brake divides on the oil pump 12, brake divides oil pump 12 all to be provided with or part is provided with pressure sensor 4.
