Preferably, antitheft shell inwall has inwardly outstanding snap ring, and corresponding, the outermost end of said transparency cover is provided with outwards outstanding snap ring; The two matches, and the shell that prevents to guard against theft is firmly outwards extracted to come off.
The end face of transparency cover is provided with the dismounting hole, inserts the dismounting hole with the purpose made dismantling devices, could the closure of transparency cover and pedestal formation be unclamped from tire tube valve, thereby simple and easy electronic type tire pressure monitoring device of the present invention is disassembled from tire.
Said pressure monitoring circuit comprises flash lamp circuit plate, supplying cell, sensor circuit board.On the said flash lamp circuit plate LED unit is set; Said sensor circuit board is fixed on the pedestal, and pressure sensor, temperature sensor and main control unit are set on this circuit card.Pressure sensor and temperature sensor be respectively to main control unit output wheel tire pressure value signal and temperature value signal, and main control unit judges whether tire pressure value signal and temperature value signal be normal, and control LED sends wink signal in the unit under improper situation.Preferably, said main control unit also detects the dump energy of supplying cell, and control LED sends wink signal in the unit when electric weight is not enough.For distinguish tire pressure too high, cross low or various dissimilar warnings such as battery dump energy deficiency, preferred, said main control unit is according to the different anomalies situation, control LED sends the unit wink signal of different frequency and color.
Preferably,, seal ring is set, prevents that the exterior water of said closure from getting in the shell at transparency cover and pedestal junction in order to increase the water resistance of said closure; At pressure monitoring circuit and pedestal junction seal ring is set, prevents that the moisture content of inside tires from infiltrating sensor.
Simple and easy electronic type tire pressure monitoring device of the present invention is directly fixed on the tire tube valve of outside tires; Compare existing tire pressure monitoring device, simple and easy electronic type tire pressure monitoring device of the present invention can effectively prevent to steal the airtight waterproof dependable performance; And simple in structure, the warning intuitive and convenient.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is the physical construction block diagram of the simple and easy electronic type tire pressure monitoring device of the embodiment of the invention;
Fig. 2 is the circuit structure diagram of the simple and easy electronic type tire pressure monitoring device of the embodiment of the invention.
The specific embodiment
In order to make those skilled in the art person understand technical scheme of the present invention better, and make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, below in conjunction with embodiment and embodiment accompanying drawing the present invention done further detailed explanation.
Fig. 1 is the physical construction block diagram of the simple and easy electronic type tire pressure monitoring device of the embodiment of the invention.Transparency cover 1 is combined into an osed top shell with pedestal 3 through threaded engagement.Pedestal 3 is used for whole device is fixed on the exterior tire tube valve of motor tire, like figure, has screw thread at pedestal 3 terminal inwalls, can combine with the screw thread on the tire tube valve.Admission port 4 inserts tire tube valve, is communicated with tire valve and above-mentioned closure, makes the pressure and temperature that can detect inside tires gas at closure pressure inside observation circuit 5.Said pressure monitoring circuit 5 comprises flash lamp circuit plate 6, supplying cell 7 and sensor circuit board 8.Flash lamp circuit plate 6 is positioned at the below of transparency cover, is provided with two LED unit; Sensor circuit board 8 is fixed on the pedestal 3, and pressure sensor P_SENSOR, temperature sensor T_SENSOR and main control unit U2 are set above; Supplying cell 7 contacts with negative pole shell fragment 10 with anodal shell fragment 9, and the circuit part that is used to simple and easy electronic type tire pressure monitoring device of the present invention provides electric energy.To come to introduce in detail with reference to Fig. 2 below about pressure monitoring circuit more than 5 particular contents.
In order to make monitor inside airtight fully, prevent that moisture content from getting into the normal operation of monitor internal influence pressure monitoring circuit 5, in transparency cover 1 and pedestal 3 junctions seal ring 14 is set, prevent that the exterior water of said closure from getting in the shell; In sensor circuit board 8 and pedestal 3 junctions seal ring 15 is set, prevents that the moisture content of inside tires from infiltrating sensor.In addition, in the junction of pedestal 3 and tire valve oil sealing 16 is set.
Fig. 2 shows in detail the circuit structure diagram of the pressure monitoring circuit 5 of the embodiment of the invention.Whole pressure monitoring circuit 5 adopts 3V system electricity former, system's timing working, and detection wheel tire pressure and temperature and battery electric quantity during work, pressure monitoring circuit 5 is in dormant state at ordinary times, and power consumption is extremely low.
During work, the GP4 pin of main control unit U2 output high level is through filter capacitor C1, for pressure sensor P_SENSOR, temperature sensor T_SENSOR (can use diode or thermally dependent resistor) and amplifier U1A provide working power.Pressure sensor P_SENSOR detects gaseous tension, and output voltage is to the 6th pin GP1 of main control unit U2 after amplifier U1A amplifies in its output, and main core unit U2 pin thus obtains the tire pressure value signal.Temperature sensor T_SENSOR output is through resistance R 6, and capacitor C 3 arrives the 7th pin GP0 of main control unit U2, thereby makes main control unit U2 obtain the tyre temperature value signal.Main control unit U2 is converted to the pressure and temperature data of tire through A/D.Through calculating; Main control unit U2 confirms whether current tire pressure and temperature be normal; If note abnormalities, main control unit U2 is then through the 2nd and 5 pin output drive signals, via resistance R 9; R10 outputs to the LED unit LEDs 1 and the LED2 of flash lamp circuit plate 6, and LED1 and LED2 are the light-emitting diode of different colours.According to the different anomalies state, main control unit U2 sends different drive signals, makes the LED unit send the flash signal of different frequency and color.In addition, main control unit U2 also relatively obtains the cell pressure data through the builtin voltage collection, confirms whether current cell pressure is normal, and same driving LED unit flashing light is reported to the police under abnormal situation.
The above is merely the specific embodiment of the present invention, and the present invention can also be applied in other control convenience.Protection scope of the present invention is not limited thereto, and any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
