Description
[technical field]
The present invention relates to automobile security protection accessory equipment, relate in particular to a kind of tire gauge and air faucet connecting structure.
[technical background]
The tire gauge of motor tire is connected with valve, and forming independently, product has been the general knowledge of this area for selling.Relevant technology evolution see for details comprise the applicant patent (application) at interior countries in the world patent documentation.
The tire gauge that known patent documentation discloses and the connection structure of valve, existing consideration by outwards emission and realize the structure of tire gauge and the physical connection of valve of valve, also has the tire gauge internal signal to keep electrically not being connected between tire gauge and the valve and the structure of connection physically.
Typically see the CN200910260535.1 patent application that the applicant submitted on December 10th, 2009; it discloses a kind of water proof type tire pressure detecting device and cylindrical solenoid protective case; in the tire gauge that its Fig. 3 discloses and the connection structure of valve; the valve end is designed to globular part; the tire gauge shell is formed with the groove of accommodating this globular part; globular part closely engages with this groove and can relatively rotate; such structure can be convenient to finely tune tire gauge with respect to the reclining angle of valve after tire gauge is installed, thereby can not prized from destruction by pry easily so that tire gauge is close to race.The defective that this kind structure has is that globular part and groove mechanical wear with the passing of time easily cause tire gauge to get loose.
On January 6th, 2010, disclosed CN201376472Y patent announcement disclosed a kind of structural improvement of tire pressure detector, it is based on the same principle that is pivoted, always pass to the screw of groove in the design of tire gauge groove back, pass the default screw phase screw lock of this screw and Universal-head by a screw and realize that the activity of tire gauge and tire tube valve fixes, the structure of this improvement can effectively prevent because of getting loose that mechanical wear occurs, and but brings another similar problem.Although be mainly manifested in and realize screw lock between screw and the Universal-head screw, but the pivot point between valve Universal-head and the tire gauge groove is not on the axis of valve, and the position that forms groove is difficult to be processed into the shape concentric with Universal-head, like this, process when the relative valve reclining swing of tire gauge, be equivalent to the process of eccentric rotary, distance between the nut of screw and the groove back wall changes during this time, therefore, in order to make relatively valve flexible rotating of tire gauge, must make this screw go deep into the distance of valve Universal-head enough large, so that this apart from can so that the nut of this screw just match with the thickest back wall of groove, and can be in this position because the back wall of groove is too thick limited in rotation.Yet too getting loose of screw must affect its fastening effect, also can be so that become loose between valve globular part and the tire gauge groove, and screw easily reverses, and tire gauge and valve be just easily disengaging also.Therefore, even add screwing (bolt), also there is defective in this connection structure.In addition, in the universal structure of this technical scheme, the spacing of rotation direction about valve is to compel plane involution by the folder of the plane of orientation on the Hooke's coupling and guide groove both sides to realize, this structure is not considered other situation that bolt matches with Hooke's coupling fully.
Below all be only consider between tire gauge and the valve physical structure for example, generally be the outer directly emission of the sky alignment tire electric signal by tire gauge inside in this case, well-known, wire net gathers in the tire, these wire nets consist of shielding cavity with wheel hub, weaken widely the power level of the signal of outwards launching in tire.Some like products have on the market been further considered situation about being electrically connected between tire gauge and the valve.Comparatively general, be directly the transmission circuit of tire gauge internal emission signal and the metal piece of valve to be electrically connected, carry out the signal emission take valve as antenna.In the case, signal is drawn outside the tire in the tire, no longer shielded easily, yet in case water inlet around the valve, valve is connected with wheel hub, and the signal emission can't normally send because of short circuit again.And because reckoning without the relatively large signal transmission power, signal of affecting of valve resistance to the situations such as load point of valve, present this product is difficult on market fully to be approved by the customer.
Further, get back on the physical structure, more than enumerate each example, in case the maintainer destroys tire gauge the metal piece because valve is attached most importance to accidentally when the stripping tire, tire gauge is generally Plastic Parts or light metal spare, and general tire gauge can be destroyed by whole, and valve can continue to use.But the cost of tire gauge is obviously far above valve, and therefore, on the basis that addresses the aforementioned drawbacks, the economic loss when how effectively to reduce the generation of artificial damage accident should be considered equally.
[summary of the invention]
The object of the present invention is to provide that a kind of electric property is excellent, stabilized structure and tire gauge and air faucet connecting structure with collision preventing and loss reducing characteristic.
For realizing this purpose, the present invention adopts following technical scheme:

The first related parts comprises stoping the locating part that self passes through this guide groove;
Insulating fixing piece is set in the valve periphery so that valve and wheel hub insulation are fixing;
One of two relateds parts match fixing through this guide groove with another related parts;
The signal of tire gauge transmission circuit covers sheet, the first related parts, the second related parts, Universal-head, valve to spatial emission through this conduction in succession.
This locating part and conduction are covered and are provided with the pad slide block between the sheet, and the pad slide block is provided with the through hole that passes through for one of related parts.The face that described pad slide block covers sheet towards conduction is the spill smooth sphere.Described pad slide block and described locating part face toward each other are provided with one of at least the dentalation of increasing friction force.Better, described pad slide block and described locating part face toward each other are equipped with intermeshing dentalation.
Described valve comprises the tubular body, and body from the air extractor duct that the tube wall side passes, is provided with thickness less than the weak link of body all the other position thickness around this body in the formation one of air inlet end.Described weak link is through described air extractor duct setting.
Described conduction is covered sheet, the first related parts and the second related parts and is conducting metal spare.Described conduction is covered between the transmission circuit of sheet and described tire gauge and is serially connected with nonisulated multiturn coil.Described nonisulated multiturn coil is cylindrical solenoid.
Described the first related parts is bolt, and its nut is defined as described locating part, and described the second related parts is the screw that is preset on the Universal-head.Perhaps, described the first related parts is nut, is defined as described locating part, and described the second related parts is integrated the screw that is preset on the Universal-head.
This connection structure also comprises and the integrated buffer part of shell, and this buffer part places conduction to cover between sheet and the Universal-head.This buffer part have the conduction of substituting cover sheet directly with the universal interior concave spherical surface that is connected of Universal-head, and cover the outer concave spherical surface that the interior concave spherical surface of sheet fits with conduction, and cover the slotted eye of the corresponding perforation of the guide groove of sheet with conduction.
It is one-body molded that described conduction is covered body and the tongue piece of sheet, and tongue piece is the bending extension of body.Described conduction covers sheet and valve is copper metallic conduction spare.
In one embodiment of the invention, described insulating fixing piece is one to be the India rubber tube of sleeve-shaped, and this India rubber tube is provided with the fixing annular groove that contacts with the circular hole of wheel hub in the side near Universal-head.And in another embodiment of the present invention, described insulating fixing piece comprises seal gasket, the first rubber cushion, nut, the second rubber cushion and the dust cap that in succession is set on the valve, the first rubber cushion and the second rubber cushion are established respectively at nut two ends pad, form one between seal gasket and the first rubber cushion for the fixing annular groove that insulate mutually of the circular hole with wheel hub, nut and valve phase screw lock, dust cap also with valve phase screw lock with the encapsulation valve admission port.
Compared with prior art, the present invention has following advantage:
At first, set conduction is covered sheet, because it keeps concentric setting with Universal-head, therefore when valve drives the first related parts and carries out reclining and swing, the locating part of the first related parts can cover between the face of body of sheet with same width and conduction and keep the distance, so just, reinforced being connected between the first related parts and second related parts, so that both connections are difficult for getting loose, the further cooperation by a smooth concave design of dentalation another side of described pad slide block, again so that locating part can drive pad slide block synchronous slide when activateding, and then tighten each other between pad slide block and the first related parts, like this, both so that being connected between tire gauge and the valve is more firm, guaranteed again can relatively rotate neatly between tire gauge and the valve.
Secondly, conduction is covered the setting of sheet, when realizing firm the connection, also owing to its tongue piece stretches into the inner effect that realizes the signal transmission of tire gauge, like this, the tire gauge internal signal can cover sheet, the first related parts, the second related parts through conduction, launch to outside tires by valve at last, because these parts especially conduct electricity and cover sheet and valve has adopted copper metal material, impedance is low, electric conductivity is good, therefore the transmission quality of signal is higher; And the valve periphery is provided with insulating fixing piece, can effectively stop again valve directly or indirectly to contact the formation short circuit with wheel hub; Further again, owing to being serially connected with multiturn coil between tongue piece and the tire gauge transmission circuit, can play simultaneously the double action of impedance match and antenna, so when valve works as the signal radiated element, can obtain higher transmission over radio stability and signal transmission distance far away owing to the impedance match effect of multiturn coil.
Again, conduction is covered the setting of sheet, when realizing firm the connection, the intensity of valve body has virtually relatively also weakened, be combined in the technological means that weak link is set on the body, make body in the radial wall thickness attenuation at weak link place, collision preventing and loss reducing mechanism in the structure that connects thus, particularly, because the reduction of other position of the relative valve of weak link mechanical strength, when the tire gauge on being installed in wheel hub is subject to external impacts, owing to firmly being connected with the tire gauge shell between Universal-head and the first related parts, also relatively between valve body and the wheel hub firmly connect, unique weakness is this weak link, and the weak link place is prone to fracture under the external impacts, like this, though tire gauge can break away from valve, but what destroy is the structure of valve, and does not relate to tire gauge itself, because the cost of valve is cheap far beyond tire gauge, this measure just can be saved for the user service expenditure of great number, only needs to change valve, continuing to employ tire gauge gets final product.
In addition, although only conduction is covered and can be realized above-mentioned effect of the present invention between sheet and the Universal-head, but and the integrated buffer part of shell set up the annexation that can further consolidate between Universal-head and the shell, at this moment, because conduction is covered the path of motion that guide groove is used for guiding the first related parts has been set in the sheet, the slotted eye role of buffer part is relatively limited, slotted eye only need provide enough activity spaces to get final product to the first related parts is movable, thereby, when the shell of design tire gauge, needn't excessively pay close attention to transverse width and the shape of this buffer part slotted eye on the shell, on the other hand, because shell generally adopts Plastic Parts, can process the buffer part with relatively thick by lower cost, so that between the first related parts and the second related parts larger operational space is arranged, and the conduction that needn't directly thicken the higher metal of cost is covered sheet, obviously has the advantage of saving cost.
Although summarized as mentioned above major advantages more of the present invention, therefore advantage of the present invention is not limited to, and any foundation technological means of the present invention and the technique effect that directly or indirectly draws should be forgiven in essence technique effect of the present invention.
