Abstract
The utility model provides a display alarm device for monitoring air pressure of tyre, which is composed of an air-pressure sensor, an air and electricity conversion device and a sound and light display alarming device. The utility model is characterized in that a flexible shaft pull wire is adopted to pick up air-pressure displacement signals in the air-pressure sensor and to transmit the air-pressure displacement signals to an adjustable capacitor in the air and electricity conversion device; the air-pressure displacement signals are converted into electric signals, and are treated via a circuit, making the sound and light display alarm device send out signals to remind a driver to take corresponding measures. The utility model is very practical for monitoring the air pressure of aircraft tires.
Description
The utility model relates to a kind of monitoring tire pressure displaying alarm.
All automobile, motor bikes, and the tire of various power actuated vehicles at present, air pressure deficiency or superpressure cause that traffic accident is quite a lot for a certain reason, other two kinds of displaying alarm I type and II types of monitoring tire pressures of my application simultaneously.All in vehicle ', monitor, monitor if tire does not rotate less than.
The purpose of this utility model provides a kind of new monitoring tire pressure displaying alarm, and whether it not only can monitor tire pressure when tire rotates normal, even also can monitor when tire does not rotate.Whether especially can in time monitor its air pressure when aircraft tyre does not put down as yet normal.
The utility model can reach by following measure:
The utility model is by baroceptor, pneumatic-to-current converter, the acoustooptic display alarm device sequence is formed by connecting, it is characterized in that displacement signal transmission that it also adopts a flexible axle backguy to pick up the air pressure pad in the baroceptor gives the adjustable condenser in the pneumatic-to-current converter, with the air pressure displacement signal, be converted to the signal of electricity, and then the oscillator of process general circuit, links such as voltage multiplying rectifier amplifies, and is anti-phase are to the acoustooptic display alarm device.
Baroceptor recited above, it is linked in sequence by shell, rubber pneumatic bag or metal bellow, pad and spring and is assembled, and it is mounted on the tire tube valve of tire.
Adjustable condenser recited above, it is by a leak free, is fixed on the vehicle body adjustable capacitor C5 that the fixed capacity C4 that constituted near the plating semicircle electrode slice (A) at axletree position and a plating entelechy sheet (B) that is installed in wheel side and air pressure displacement signal that is come by flexible axle backguy transmission constituted and is combined.
Pneumatic-to-current converter recited above, it comprises the oscillator of adjustable condenser and general circuit, multiplication of voltage, rectification, amplification, link such as anti-phase.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a baroceptor profile construction scheme drawing.
Fig. 2 is the functional-block diagram of monitoring tire pressure displaying alarm.
Fig. 3 is the circuit diagram of the pneumatic-to-current converter of monitoring tire pressure.
Fig. 4 sound, light Display and Alarm Circuit figure.
The utility model is described in further detail below in conjunction with drawings and Examples:
Among the figure: 1, baroceptor, 2, the flexible axle backguy,
3, sealing tunable capacitor device, 4, oscillator,
5, multiplication of voltage, rectification, amplification, anti-phase device, 6, sound, light, displaying alarm,
7, rubber pneumatic bag, 8, pad,
9, spring.
Fig. 1 is a baroceptor, it is contained on the tire valve, rubber pneumatic bag (7) or metal bellow are housed in it, what head on air bag (7) in addition is pad (8), the another side of pad is spring (9), the adjustable capacitor (3) of pad and baroceptor outside, connection is to utilize flexible axle backguy (2), when tire pressure changes, also along with flexible, under the effect of spring (9), pad will be done corresponding displacement according to the size of tire internal gas pressure to air bag in the baroceptor, through the transmission of flexible axle backguy (2), drive adjustable capacitor.
Fig. 2 is the functional-block diagram of monitoring tire pressure sound, light displaying alarm, and the Pneumatic pipe cleaner that baroceptor is picked up is crossed flexible axle backguy transmission and given adjustable capacitor, and this moment is by the more stable frequency 10KH of oscillator output
2The square wave alternating-current electricity is through C2, C3, C4, the structure of C5
Claims (3)
1, a kind of displaying alarm of monitoring tire pressure, it is by baroceptor, pneumatic-to-current converter, the acoustooptic display alarm device sequence connects institute and constitutes, and it is characterized in that it also adopts a flexible axle backguy to pick up air pressure pad displacement signal transmission in the baroceptor to the adjustable condenser in the pneumatic-to-current converter.
2, a kind of displaying alarm of monitoring tire pressure according to claim 1 is characterized in that described baroceptor, and order is equipped with rubber pneumatic bag or metal bellow, pad and spring in it.
3, a kind of displaying alarm of monitoring tire pressure according to claim 1, it is characterized in that described adjustable condenser is a leak free, be fixed on the vehicle body adjustable capacitor C5 that is constituted near the fixed capacity C4 of the plating semicircle electrode slice (A) at axletree position and the formation of a plating entelechy sheet (B) that is installed in wheel side and air pressure displacement signal that comes by flexible axle backguy transmission and combined.
