Abstract
A tyre pressure warner has a push assembly arranged in a lower seat and a warning system. Said push assembly is composed of positive and negative pressure adjuster, piston rod and compression spring. Said warning system consists of transmitter, power supply body, pressure switch and receiver. When tyre pressure is overhigh, the piston rod is pushed up to make the conducting pressure control plate in touch with high-pressure contact and the pressure switch is closed to turn on the transmitter to transmit overhigh signal. When tyre pressure is overlow, the piston rod is pushed down to make the conducting pressure control plate in touch with low-pressure contact to transmit overlow signal in same manner. The signals are received by the receiver.
Description
The present invention relates to a kind of tyre pressure alarm, relate in particular to a kind of have in the use high-reliability and easy and stack-mounted tyre pressure alarm.
As shown in Figure 1, this is that a kind of tire pressure that can detect is simultaneously crossed the low tyre pressure alarm that reached high state, it is TaiWan, China patent the 186th, 905 notification numbers are entitled as " improved device of tyre pressure alarm ", it mainly comprises a body skin 10, a capping 11, an inverted T shape push rod 12, alarming device 13 and a cover body 14 with first circuit board 130 and second circuit board 131, when measuring the motor tire of normal pressure, tire pressure enters Hou from air extractor vent 101, if enough pushing away this pressure-bearing film 15, the strength of tire pressure draws, make this push rod 12 upwards pass, this push rod 12 will pass the medium pore 132 of this second circuit board 131 and the 3rd conductive reed 133 will upwards be pushed away, make it break away from the situation that both positive and negative polarity is connected, so, this light-emitting diode 134 will can't be luminous because of the short circuit of power supply, and be normal with regard to the tire pressure of representing tire this moment.On the contrary, if the strength deficiency of tire pressure upwards passes this pressure-bearing film 15 and push rod 12 to the conducting state that the 3rd conductive reed 133 is broken away from this second circuit board 131, then the 3rd conductive reed 133 will remain on the situation that both positive and negative polarity is connected, and be not enough must replenish with regard to the tire pressure of representing tire this moment.In addition, if the strength of tire pressure is excessive, and this pressure-bearing film 15 and push rod 12 are upwards passed, the conducting state that the 3rd conductive reed 133 is broken away from this second circuit board 131, and move to above-mentioned first circuit board 130 on continuing and touch first conductive reed 135, again when conflicting this second conductive reed 136 by this first conductive reed 135, then the 3rd conductive reed 133 is with second conductive reed 136 of conducting on first circuit board 130, just represent the tire pressure of tire too high this moment, and the user must do suitable losing heart.By above-mentioned structure, though whether can detect tire pressure simultaneously too high or too low,, still have following shortcoming:
1. the fiduciary level on using is lower, and service life is shorter.When the body skin 10 of this tyre pressure alarm is fixed on the cranked tire valve, no matter the tire pressure of tire is at normal, too high or too low state, pressure-bearing film 15 always must bear the last thrust amount of tire pressure, make its central depression 150 be the state of heaving, this film 15 is the elastic stretch strength that relies on material face, can't be as the spring durable, after using for a long time, originally rubber-like pressure-bearing film 15 will inevitably produce elastic fatigue, and then causes the error in the detection.
2. assembling inconvenience.It must could lock capping 11 and first and second circuit card 130,131 on body skin 10 by means of the use of screw 16,17, and number of parts is many, and causes the inconvenience in the assembling.
Order of the present invention is to provide a tyre pressure alarm, and it not only has high-reliability in the use, and assembling easily.
The object of the present invention is achieved like this:
A kind of tyre pressure alarm comprises:
A lower base, this lower base is inner to form a room, the one end can be fixed on the cranked tire valve, in be provided with a push rod, and be provided with an inlet channel in these push rod central authorities, be provided with one in the room of this lower base and promote assembly,
A upper cover body, its cover cap pairing this above lower base,
Be characterized in:
Described promotion assembly comprises that one has the positive negative value adjustment part of pressure of perforation, a piston rod and a compression spring,
The positive negative value adjustment part of this pressure is located at this room top, and links with the internal face of this room,
The edge that supports of this piston-rod lower end is to be against this room bottom airtightly, and the perforation with the positive negative value adjustment part of this pressure can be worn in its upper end, and moves up and down when tire pressure is too high or too low,
Described compression spring be ring set outside this piston rod, the one end is against the edge that supports of this piston rod, the other end is against the apical margin of the positive negative value adjustment part of this pressure;
Permanent seat of described upper cover body internal lock knot, and the locking of the lower part of this permanent seat is at the internal face of this lower base;
This tyre pressure alarm also comprises:
One caution system, this caution system comprise a feedway, a power source body, a pressure switch and a receiving device;
Described feedway is located in the permanent seat of this upper cover body, in order to launch a radio signal;
Described power source body is located in the permanent seat of this upper cover body, as the power supply of this feedway;
Described pressure switch is located between the permanent seat and lower base of this upper cover body, comprise a high-low pressure control conducting strip, a high-voltage contact and a low-voltage contact, this high-low pressure control conducting strip is located at the piston rod upper end of this promotion assembly, and along with this piston rod moves together, this high-voltage contact and low-voltage contact are to be electrically connected at this power source body and this feedway, and the formation loop, between this high-low pressure control conducting strip and high-voltage contact, form a high pressure detector switch, and between this high-low pressure control conducting strip and low-voltage contact, form a low pressure detector switch;
This receiving device is in order to receive this feedway institute emitted radio signal.
The present invention not only overcomes the shortcoming of prior art owing to adopt above-mentioned technical scheme, reaching purpose of the present invention, and has following advantage:
1. the fiduciary level on using is higher, and service life is longer.The present invention is owing to replace the pressure-bearing film with piston rod and spring, therefore can not cause the pressure-bearing film to use the back to make it to detect the situation of error because of elastic fatigue for a long time, thereby improved tyre pressure alarm fiduciary level in the use relatively, make spring have bigger fatigue limit and elastic force scope, service life is longer.
2. just what assembling.The present invention need not use screw fully owing to by the inside and outside wall thread cutting at each primary member, make the present invention when assembling, and is therefore easy to assembly.
By the description of following some embodiment to tyre pressure alarm of the present invention, can further connect purpose of the present invention, architectural feature and advantage in conjunction with its accompanying drawing.Wherein, accompanying drawing is:
