The specific embodiment
In order to make goal of the invention of the present invention, technical scheme and useful technique effect thereof more clear, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.Should be understood that, the specific embodiment of describing in this specification sheets only is in order to explain the present invention, is not in order to limit the present invention.
See also Fig. 1 and Fig. 2, be the structural representation of baroceptor 10 of the present invention, 10a.The bearing support 12 of described baroceptor 10,10a is the rubber plastic material, and bearing support 12 comprises base plate 120, sidewall 122 and top board 124, and all plate bodys of bearing support 12 surround a receiving space 125 jointly.Offer through hole 126 on the top board 124 of bearing support 12, offer perforation on the base plate 120, the ventilation flue 128 that receiving space 125 is communicated with atmosphere is installed in the perforation, three non-touching electric-conductors (shown in the figure in the embodiment three electric-conductors all be bolt) also is installed: the spring leaf connecting element 14 that is connected with electric power connection line 140, the low pressure regulating part 16 that is connected with low-pressure continuous wiring 160 and the high voltage adjusting part 18 that is connected with high-pressure connection line 180 on the base plate 120.The bottom of three electric-conductors is individually fixed in the base plate 120 of bearing support 12, the top is then all stretched in the receiving space 125 of bearing support 12, wherein, the top of low pressure regulating part 16 is equipped with sheetmetal 162, the top of spring leaf connecting element 14 is equipped with spring leaf 142, one end of spring leaf 142 is fixed in spring leaf connecting element 14, the other end is free end, sheetmetal 162 applies certain precompressed compression with the upper surface overlap joint of spring leaf 142 and to spring leaf 142, and the top of high voltage adjusting part 18 is positioned at the free-ended below of spring leaf 142.Near free end piston 144 is housed on the spring leaf 142, stretch out in the through hole 126 of top board 124 at the top of piston 144: when 142 applied pressures of 144 pairs of spring leafs of piston during less than or equal to the first preset value, spring leaf 142 will keep contacting with sheetmetal 162, the low-pressure continuous wiring 160 that is connected with projector will make the low voltage circuit conducting and produce the low pressure alarming signal, and projector namely carries out low pressure alarming; When 142 applied pressures of 144 pairs of spring leafs of piston greater than the first preset value during less than the second preset value, spring leaf 142 no longer contacts stressed downward distortion with sheetmetal 162, hi-lo circuit all disconnects, and does not produce alarm message; When 142 applied pressures of 144 pairs of spring leafs of piston increase to more than or equal to the second preset value, the free end of spring leaf 160 will drop to the top of high voltage adjusting part 18 and contact, the high-pressure connection line 180 that is connected with projector will make the high voltage circuit conducting and produce the alarm for high voltage signal, and projector namely carries out alarm for high voltage; After the tire internal gas pressure descended, the antagonistic force of spring leaf 142 went up pushing piston 144 and alarm for high voltage is removed, if tire pressure descends too much, spring leaf 142 can again go back up to and contact with sheetmetal 162 and cause low pressure alarming.
See also Fig. 1, the first embodiment of baroceptor 10 of the present invention is be used to the motor tire that does not have the inner tube of a tyre, need during use at the top board 124 of its bearing support 12 gland 30 to be set, the material of gland 30 is plastics, it is sealingly fastened in a sheet rubber 32 top of piston 144, and sheet rubber 32 contacts with piston 144 and the receiving space 125 of bearing support 12 inside is isolated fully with the cavity 36 of sheet rubber 32 tops.Offer the induction opening 34 that the cavity 36 that makes sheet rubber 32 tops is communicated with motor tire on the gland 30, guarantee that the air pressure in the cavity 36 is identical with the motor tire internal gas pressure.When baroceptor 10 is installed on wheel hub inside, ventilation flue 128 set on the base plate 120 of its bearing support 12 is communicated with atmosphere, 34 of the induction openings of gland 30 are communicated with inside tires, and the pressure of gas forces sheet rubber 32 distortion and to piston 144 application of forces in the tire.
See also Fig. 2, the baroceptor 10a of second embodiment of the invention is be used in the motor tire that the inner tube of a tyre is arranged, it is inner and contact with the inner tube of a tyre 20 that baroceptor 10a is installed on wheel hub during use, ventilation flue 128 set on the base plate 120 of its bearing support 12 is communicated with atmosphere, and 144 in piston contacts with the inner tube of a tyre 20 and directly exerted pressure by the inner tube of a tyre 20.
At above two embodiments, the first preset value of described piston 144 pressure and the second preset value all are that the gas pressure intensity critical value in the tire arranges during according to low pressure and alarm for high voltage, can adjust as required in the practical operation, as the first preset value is set as gas pressure intensity in the tire less than tire standards air pressure 25% the time piston 144 suffered pressure, with the second preset value be set as gas pressure intensity in the tire greater than tire standards air pressure 30% the time piston 144 suffered pressure.
By above description as can be known, baroceptor of the present invention is by sheet rubber 32 or 144 pairs of spring leaf 142 application of forces of automobile inner tube 20 pushing pistons, spring leaf 142 produces in various degree distortion according to the size of pressure, and contacts with low pressure regulating part 16/ high voltage adjusting part 18 when pressure threshold and make low voltage circuit/high voltage circuit conducting and produce low/alarm for high voltage signal.Above-mentioned baroceptor not only simple in structure being convenient to is produced, and can be used on the motor tire of the inner tube of a tyre 20.
