The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in Figure 1 to Figure 3, tyre pressure sensor and the valve assembly 10 of a preferred embodiment of the present invention proposition comprise a valve 20, a tyre pressure sensor 30, a bolt 60.
Valve 20 has a junction 22, and connecting portion 22 has a relative top 221 and a bottom 222, is the planar external-adjuster face 224 of circular arc, and one is the planar outer bearing surface 226 of circular arc.This top 221 is a straight line (such as Fig. 2 and shown in Figure 4).External-adjuster face 224 221 extends towards two opposite directions and towards this bottom 222 from the top, and outer bearing surface 226 and top 221 are vertical and extend to bottom 222 from external-adjuster face 224 peripheries.
Another embodiment of the present invention is that connecting portion 22 is cylindric, only has external-adjuster face 224.
Further, valve 20 has a perforation 24 and one air-filled pore 26(as shown in Figure 4).Perforation 24 from the top 221 of connecting portion 22 by this external-adjuster face 224 and run through this valve 20.One end of air-filled pore 26 is communicated with perforation 24, and the other end is positioned at the outer bearing surface 226 of connecting portion 22 and is communicated with the outside of valve 20.
As shown in Figure 5, tyre pressure sensor 30 has a housing 40, and a sensing cell 50 in order to sense gasses pressure and temperature of being located in the housing 40, and housing 40 also can cover and establishes one in order to hide the cover plate (not shown) of one opening 41.Structure and the function of sensing cell 50 belong to prior art, and this does not give unnecessary details.The bottom of housing 40 has a link slot 42, and link slot 42 has an opening 421 and relative with this opening 421 a planar interior adjustment face 422 of circular arc that is, and adjustment face 422 extends to a rear end 424 from the front end 423 of link slot 42 circular-arcly in this.In addition, housing 40 also has a slotted hole 44 and a bolt support 46, slotted hole 44 by link slot 42 interior adjustment face 422 and run through housing 40, this bolt support 46 can be used for the head of bolt 60 is tight against on it.
And for example shown in Figure 5, in the housing 40 of the tyre pressure sensor 30 that the present embodiment provides, the dual-side of the interior adjustment face 422 of link slot 42 is connected respectively one and is planar the first interior bearing surface 426 and of circular arc and is the second plane interior bearing surface 428, two first interior bearing surfaces 426 are connected with the front end 423 of link slot 42, and two second interior bearing surfaces 428 relatively are parallel and are connected with the rear end 424 of link slot 42.Whereby, the first interior bearing surface 426 and the second interior bearing surface 428 can be connected to the outer bearing surface 226 of the connecting portion 22 of valve 20, move past at link slot 42 metas with the connecting portion 22 that prevents valve 20 many, and then can more easily lock housing 40 and valve 20.
When assembling valve 20 and tyre pressure sensor 30, first the connecting portion 22 of valve 20 is arranged in the link slot 42 of housing 40 of tyre pressure sensor 30, so that interior adjustment face 422 shape complementarities of the external-adjuster face 224 of connecting portion 22 and link slot 42 and can relatively rolling.Like this, as shown in Figure 6 and Figure 7, the external-adjuster face 224 of connecting portion 22 can roll towards front end 423 or the rear end 424 of link slot 42 with respect to the interior adjustment face 422 of link slot 42, with the relative angle of change valve 20 with the housing 40 of tyre pressure sensor 30.
Then, adjust relative angle after, bolt 60 passed the slotted hole 44 of housing 40 and be locked in the perforation 24 of valve 20, the housing 40 of tyre pressure sensor 30 is interfixed with valve 20, at this moment, the air-filled pore 26 of valve 20 is positioned at outside the tyre pressure sensor 30.Therefore, when tyre pressure sensor and valve assembly 10 are installed in a wheel (not shown), can enter tire via air-filled pore 26 by perforation 24 gases that enter valve 20.The more important thing is, because the connecting portion 22 of aforementioned valve 20 can't towards arbitrary directional rolling, therefore can be easier to lock the action of establishing bolt 60.
Except above embodiment, the embodiment of tyre pressure sensor provided by the present invention and valve assembly, also can slightly following variation:
For example, the external-adjuster face 224 of the connecting portion 22 of valve 20 is isometrical circular arc not necessarily, and it also can be isometrical circular arc and changes eccentric setting, or with gradual change footpath circular arc, to cooperate the various demands such as other structure or adjustment position.
For another example, the outer bearing surface 226 of the connecting portion 22 of valve 20 except as aforementioned and the top 221 of connecting portion be vertical, the outer bearing surface 226 of the connecting portion 22 of valve 20 also can be predetermined angle with the top 221 of connecting portion 22, and the formation taper.
Comprehensive above explanation, tyre pressure sensor provided by the present invention and valve assembly 10, the connecting portion 22 of its valve 20 is easy with link slot 42 processing and manufacturings of housing 40, and is convenient to that combination is assembled and precision is good accurately, and can reach the effect that tyre pressure sensor and valve 10 are firmly made up.
It should be noted that; above content is in conjunction with concrete embodiment further description made for the present invention; can not assert that the specific embodiment of the present invention only limits to this; under above-mentioned guidance of the present invention; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improvement or distortion drop in protection scope of the present invention.
