[detailed description of the invention]
Be further described the utility model below in conjunction with accompanying drawing and exemplary embodiment, wherein identical in accompanying drawing label all refers to identical parts.In addition, if the detailed description of known technology is for illustrating that feature of the present utility model is unnecessary, then omitted.
Fig. 1 ~ 4 show tire gauge 100 of the present utility model, be installed on tire such as motor cycle tire, for detecting the pressure of inside tires gas and the pressure of gas in tire being sent to outside tire in the mode of electric signal, receive for corresponding read out instrument and shown.Described tire gauge 100 comprises housing 1, the PCB assembly 12 be located in housing 1, the battery 13 of powering for PCB assembly 12 and the valve assembly 2 that is connected with housing 1.
Described housing 1 comprises the upper casing 10 it offering induction opening 4 and the lower cover 11 covered mutually with this upper casing 10.Described upper casing 10 offers stepped hole, and the position at this stepped hole place forms one for placing the holding tank (non-label) of described conducting ring 16.Described lower cover 11 is provided with perforation 112 in the position corresponding to described stepped hole 109.
Described PCB assembly 12 comprise it is provided with knock hole 125 in the position corresponding to described stepped hole 109 circuit card 120, be all located at control circuit, pressure sensor 121 and antenna 124 on described circuit card 120, pressure sensor 121 and antenna 124 are all electrically connected with control circuit.Described pressure sensor 121 detecting enters the pressure of the gas in housing 1 and sends corresponding electric signal to described control circuit, and electric signal described in described control circuit process also externally sends the signal characterizing gaseous tension in tire in space by antenna.Preferably, described antenna 124 is presented as pad 124 on circuit boards.
Incorporated by reference to Fig. 4, described conducting ring 16 have one penetrate described upper casing 10 and can be in electrical contact with described antenna 124 stud 161.Particularly, described circuit card passes the pad 124 of antenna and described Stud connection by a screw, and then achieves the electric connection of antenna and conducting ring.
Described valve assembly 2 comprises mouth bar 20, the first threaded shank 22 be connected with mouth bar 20 and the Nut column 3 in mating connection with this first threaded shank 22, and described Nut column 3 comprises insertion section 31 and is located at the limiting section 32 of one end, insertion section 31.
The insertion section 31 of described Nut column 3 is connected with the first threaded shank 22 of valve assembly 2 through the knock hole 125 on described stepped hole 109, circuit card 120 and the perforation 112 of lower cover, and the limiting section 32 of Nut column 3 is supported on described conducting ring 16.
When housing 1 is installed with valve assembly 2 phase, the position, hole of conducting ring 16 is passed in the insertion section 31 of described Nut column 3, the limiting section 32 of Nut column 3 contacts with this conducting ring 16, as previously mentioned, conducting ring 16 and antenna 124 are electrically connected, and thus, antenna 124 is electrically connected with conducting ring 16, Nut column 3, first threaded shank 22, inflating valve bar 20, thus pressure signal through antenna, conducting ring, Nut column and lead mouth bar, and can be launched from mouth bar.Because conducting ring, Nut column, tire tube valve are all metal piece, electric conductivity is good, so the transmission quality of pressure signal is higher, transmission distance is far away.
Further, the side along circuit card 120 longitudinally is located at by described battery 13, described pressure sensor 121, control circuit and antenna 124 are arranged on the one end near described battery 13 on circuit card 120, to make circuit card 120 form a white space in the one end away from battery 13, described knock hole 125 is opened on described white space.
Because circuit card 120 and battery 13 are near arranging, circuit card 120 is formed the white space arranged for knock hole 125, the space utilization on circuit card 120 is more reasonable, saves to utilize space in housing, reduce the size of housing 1 further, make the small volume of this tire gauge 100.
Further, described valve assembly 2 also comprises the second threaded shank 21 be located between mouth bar 20 and the first threaded shank 22 and the nut 23 be set in described second threaded shank 21.When this tire gauge 100 is installed on wheel hub, the second threaded shank 21 is inserted valve hole, be then connected with the second threaded shank 21 in wheel hub with described nut 23, thus achieve the fixing of mouth bar 20 and wheel hub.Owing to adopting multistage to fix when this tire gauge 100 is installed with wheel hub, (wheel rim of mouth bar and wheel hub is fixed, mouth bar is also fixed with tire gauge housing), although thus when housing produces centnifugal force owing to being subject to tyre rotation and causes the connection between itself and valve assembly to occur loosening, the connection of inflating valve bar and wheel rim there will not be loosening, ensure that traffic safety.
Further, adjustable in order to realize the installation site of tire gauge housing 1 in wheel hub, also comprise the locations 5 be located between housing 1 and mouth bar 20.Described locations 5 comprises the positioning seat 52 be set on described nut 23 and the cutting ferrule 51 corresponding to described stepped hole 109 and be formed on housing 1 lower cover 11, the slot 520 of matching with described nut 23 outline is provided with in one end of described positioning seat 52, the other end periphery of positioning seat is formed with external tooth 521, is provided with the internal tooth 511 (see Fig. 3) be meshed with described external tooth 521 in described cutting ferrule 51.During the assembling of this locations, described cutting ferrule 51 entangles described positioning seat 52, and described internal tooth 511 is meshed with the external tooth 521 of positioning seat 52.Owing to being provided with the internal tooth 511 and external tooth 521 that match, after cutting ferrule 51 and positioning seat 52 assemble, the two can not occurrence positions changes owing to being subject to the effect of external force, thus housing 1 can be positioned at certain position in wheel hub.
When needing the installation site of adjustment housings 1, first can unclamp the connection (internal tooth and external tooth are separated) of cutting ferrule 51 and positioning seat 52, then after forwarding housing 1 to required angle, cutting ferrule 51 is enclosed within positioning seat 52, and locks with Nut column 3 and the second threaded shank 22.As can be seen here, the described installation site of housing 1 in wheel hub is adjustable.
Further, this tire gauge 100 also comprises the taper stage clip 6 suppressed between described cutting ferrule 51 and positioning seat 52, and the large end of this taper stage clip 6 is supported on lower cover 11, and small end is resisted against on described positioning seat 52.Owing to being provided with taper stage clip 6 between cutting ferrule 51 and positioning seat 52, avoid this tire gauge 100 at rough ground or use for a long time time, the connection between valve assembly 2 and housing 1 occurs loosening and even comes off and affect the normal use of this tire gauge.Meanwhile, the large end due to taper stage clip 6 supports described housing 1, and small end is resisted against on positioning seat 52, and the centnifugal force that thus housing 1 is subject in tyre rotation process can pass on positioning seat 52 well, and then passes on wheel rim, and equilibrium of forces is good.
Although shown exemplary embodiments more of the present utility model above, but it should be appreciated by those skilled in the art that, when not departing from principle of the present utility model or spirit, can make a change these exemplary embodiments, scope of the present utility model is by claim and equivalents thereof.
