Description
Technical field
The utility model relates to baroceptor technical field, particularly a kind of tire pressure test sensor.
Background technology
Travel the large-scale carrier vehicle in rugged surroundings, its tire subjects the impact that high-low pressure, high/low temperature, strong vibration, high humility, dust and rubble clash into.TPMS system carries out real-time testing to traveling or static carrier vehicle inner tyre pressure, and carrying out giving warning in advance before having a flat tire, exploding is the effective means solving this problem.At present, most tire pressure test sensor makes antenna with inflating valve bar, and this structure is easy to, in high vibration environment, crackle occurs and causes sensor failure.Meanwhile, tire pressure test sensor outer housing selects plastic material usually, and the more difficult rubble that bears clashes into for a long time, and in sensor, sensing probe and gas port pass through sealing gasket or pour into glue and external environment condition is isolated, and measurement range is also restricted.
Summary of the invention
Technical problem to be solved in the utility model is, for above-mentioned the deficiencies in the prior art, provides a kind of tire pressure to test sensor.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of tire pressure test sensor, comprise pedestal, top, described pedestal upper end is fixedly connected with sealing adaptor, form the closed cavity of pedestal upper end, described closed cavity internal fixtion has modulate circuit plate, described modulate circuit plate is fixed with sensing probe, described modulate circuit plate is fixedly connected with the pin leads of many one end through described sealing adaptor, one end that described many pin leads stretch out described sealing adaptor is fixedly connected with antenna circuit board, described antenna circuit board is fixed with antenna, inside, described pedestal lower end offers gas port, and described gas port port is communicated with the valve cock of tire, and another port of described gas port is communicated with described closed cavity.
Described closed cavity, antenna are all arranged in the enclosure, isolate further, enlarge measurement range with external environment condition.
Described outer casing bottom offers mounting hole, can by mounting hole sensor and tire are fixed add firmly.
Described pedestal lower end outside surface is provided with screw thread, can pass through screw connection manner, is connected by pedestal by intermediate connector with tyre valve.
Described sealing adaptor offers six pin hole, in each pin hole, be provided with a described pin leads; Described pin hole aperture is 3mm, and described pin leads diameter is 1mm.
Insulated by the vitreous between described pin leads and described sealing adaptor.
Described shell internal fixtion has supplying cell; Described supplying cell is fixed in battery flat.
Described cover top portion is fixedly connected with top cover, and is sealed by sealing gasket between described shell and described top cover, can prevent the wet gas in external environment condition from entering in sensor.
Compared with prior art, the beneficial effect that the utility model has is: modulate circuit plate of the present utility model, sensing probe are fixed in closed containing cavity, expand pressure measurement scope; Vibration resistance is strong, extends serviceable life, accurately can test the pressure data of the large-scale carrier vehicle tire travelled in rugged surroundings.

Embodiment
As shown in Fig. 1 ~ Fig. 5, the utility model one embodiment comprises pedestal 14, top, described pedestal 14 upper end is fixedly connected with sealing adaptor 3, form the closed cavity of pedestal 14 upper end, described closed cavity internal fixtion has modulate circuit plate 2, described modulate circuit plate 2 lower surface is fixed with sensing probe 1, described modulate circuit plate 2 upper surface is fixedly connected with the pin leads 5 of many one end through described sealing adaptor 3, one end that described many pin leads 5 stretch out described sealing adaptor 3 is fixedly connected with antenna circuit board 6, and described antenna circuit board 6 is fixed with antenna 7; Inside, described pedestal 14 lower end offers gas port 15, and described gas port 15 port is communicated with the valve cock of tire, and another port of described gas port 15 is communicated with described closed cavity.
Pedestal 14 lower end is through the bottom outlet 18 of sensor outer housing 13, and top cover 9, the sealing gasket 10 of described shell 13 and top are connected by screw 8, are provided with supplying cell 11 and the curable type glue 12 thereof of sensor in described shell.Referring to Fig. 3, when installing sensor, gas port 15 and inside tires are same equal pressure, and the sensing probe 1 be placed in the airtight cavity of pedestal 14 and sealing adaptor 3 formation detects inner tyre pressure by gas port 15, and antenna 7 sends test data.Antenna 7 is ceramic antenna.
Pedestal 14 and shell 13 are stainless steel material, integrally welded by end face.Referring to Fig. 3 or Fig. 5, pedestal 14 top is divided into tubular structure, and its cavity and sealing adaptor 3 are welded by side and form airtight cavity, and on sealing adaptor 3, in six pin hole, sintered glass matter 4 secures six pin leads 5.Modulate circuit plate 2 is welded with sensing probe 1, is weldingly fixed in airtight cavity by six pin leads 5 lower ends and also realizes the electrical connection with pin leads 5.Antenna circuit board 6 is welded with ceramic antenna, is weldingly fixed on airtight cavity by six pin leads 5 upper ends and also realizes the electrical connection with modulate circuit plate 2 outward.Referring to Fig. 4, four threaded holes 17 of shell 13 upper surface and top cover 9, sealing gasket 10 are assembled by screw 8 and compress.Sealing gasket 10 is high-temperature resistant rubber class materials, prevents the wet gas in external environment condition from entering in sensor, and modulate circuit plate 2 component surface scribbles dubbin, prevents inside tires wet gas to the oxidation of conditioning circuit board 2 and interference.The material of top cover 9 is the teflon adding carbon fiber, can prevent the shielding to transmitting and abated effect, have simultaneously hardness high, high temperature resistant, corrosion-resistant, etc. feature.Referring to Fig. 1 or Fig. 5, shell 13 right-hand member is provided with battery flat 19, by mould glue by battery curable type, again the supplying cell 11 being wrapped with curable type glue 12 is loaded in battery flat 19, this mode is convenient for changing supplying cell 11, also avoid supplying cell 11 to contact with top cover 9, the hard of shell 12 simultaneously, improve whole sensor vibration resistance.
