[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 ~ 3 show tire gauge 100 of the present utility model, are arranged on hub of motorcycle, for carrying out Real-Time Monitoring to the gaseous tension in tire, to ensure driving safety.This tire gauge 100 comprises housing 1, valve assembly 2 and Nut column 3.
The lower cover 11 that described housing 1 comprises upper casing 10 and covers mutually with upper casing 10.Described upper casing 10 offers induction opening 4.Be provided with in described housing 1 and enter the pressure of the gas in housing 10 and the PCB assembly 12 launched with electric signal by pressure signal and the battery 13 of powering for PCB assembly 12 for detecting by induction opening 4.
Described valve assembly 2 comprises mouth bar 20, be located at mouth bar 20 away from one end of admission port the first threaded shank 22, be located at the second threaded shank 21 between mouth bar 20 and the first threaded shank 22 and the nut 23 in mating connection with the second threaded shank 21.
Described Nut column 3, in step-like, comprises insertion section 31 and the limiting section 32 being located at one end, insertion section 31.Described insertion section 31 is provided with the negative thread 311 matched with the second threaded shank 22.Described limiting section 32 offers inner hexagonal hole (non-label), cross bore or a word hole in the middle, so that rotate described Nut column 3 by corresponding instrument, realizes the connection of itself and the second threaded shank 22.
Namely described housing 1 is offered its top through top of upper casing 10 (also) and bottom (being also the bottom of lower cover 11) and the stepped hole 109 matched with described Nut column 3, and the PCB assembly 12 in housing 1 is provided with knock hole 125 in the position of this stepped hole 109 correspondence, make the insertion section 31 of Nut column 3 to pass this stepped hole 109, knock hole 125, described limiting section 32 is limited to pass this stepped hole 109.
The insertion section 31 of described Nut column 3 is connected with the first threaded shank 22 of valve assembly 2 through the described stepped hole 109 of housing 1, and the limiting section 3 of Nut column 3 is pushed against on described upper casing 10, thus achieves fixing of housing 1 and valve assembly 2.
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, because the large end of taper stage clip 6 supports housing 1, 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.
Particularly, described PCB assembly 12 comprises circuit card 120, is integrated on circuit card 120 and the pressure sensor 121, control circuit and the antenna (non-label) that connect successively, and the pressure signal that pressure sensor 121 detects is accessed described antenna and launched by the sky alignment wheel hub external space by described control circuit.Preferably, one end of described antenna is expressed as pad on circuit boards.
Further, this tire gauge 100 also comprises the conducting ring 16 be located between Nut column 3 and upper casing 10.Described upper casing 10 offers the holding tank (non-label) for placing conducting ring 16, constructs described stepped hole 109 after described conducting ring 16 is placed in holding tank.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, and the limiting section of Nut column contacts with this conducting ring.Described conducting ring 16 is provided with a stud 161, and described upper casing 10 offers a through hole (not shown) and passes for this stud 161 in the position corresponding to this stud 161.Described circuit card 120 is by being connected with described stud 161 with the pad 124 of a screw 19 through antenna, thus the pad 124 of described antenna contacts with stud 161, and then antenna is electrically connected with conducting ring 16, Nut column 3, second 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, described battery 13 is located at the side of circuit card 120 longitudinally and is connected with the circuit on circuit card 120 or element by a pair battery compressing tablet (non-label).The one end near battery 13 on circuit card 120 is all located at by described pressure sensor 121, control circuit and antenna, forms a white space to make circuit card 120 away from one end of battery 13.This white space is for offering described knock hole 125.
Described upper casing establishes a boss (not shown) in the position corresponding to described knock hole, and forms the partial hole position of described stepped hole 109 in this boss, and described circuit card 120 is enclosed within described boss by its knock hole 125.
Avoid components and parts due to knock hole 125 and be opened on circuit card 120, knock hole 125 is overlapping with circuit card 120, thus saves erection space horizontal in housing 1, is conducive to the size reducing tire gauge 100.
Further, described lower cover 11 is connected with described upper casing 10 buckle.Particularly, described upper casing forms the bayonet socket corresponding to lower cover outline, by described lower cover card within it.Described boss is provided with dop in the position near lower cover, and lower cover is provided with screens in the position corresponding to dop, and when described lower cover snaps in the bayonet socket of upper casing, described dop stretches into described screens and blocked by lower cover.
