Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, wherein:
Fig. 1 illustrates the external tire pressure detection module of the utility model one embodiment, and the inner structure of module wherein is shown in the mode of semi-sictional view.
Fig. 2 illustrates the local A enlarged view of Figure 1A.
Fig. 3 illustrates the external tire pressure detection module and local figure of being connected of automotive hub of the utility model one embodiment.
Fig. 4 illustrates the A-A cutaway view of Fig. 3.
The specific embodiment
According to design of the present utility model, at first, external tire pressure detection module and automotive hub inside should be tried one's best approaching, and gas arrives the path of accepting the temperature and pressure detection in the external tire pressure detection module in the tire to shorten, and this can improve the accuracy of detection.Secondly, because automobile is in the continuous motion, and faces complicated road conditions, so external tire pressure detection module fixing on wheel hub should be very firm, and aseismicity is strong, can not come off.Moreover the shell of external tire pressure detection module also should be enough firm, in order to avoid damage, causes the in-to-in electronics package to lose efficacy.
Embodiment of the present utility model has considered above several aspects.Fig. 1 illustrates the external tire pressure detection module of the utility model one embodiment, and the inner structure of module wherein is shown in the mode of semi-sictional view.With reference to shown in Figure 1, the body shape of external tire pressure detection module 100 is column types, and its exemplary maximum gauge is 52mm, and maximum height is 69.3mm.Module 100 comprises pedestal 102, shell 101 and attaching parts 103.
Pedestal 102 and shell 101 are the basic paries that constitute product, and they assemble and form an inner chamber S, can effectively hold electronic module, and prevent that foreign object from injuring it, guarantee the function of electronic module.
With reference to shown in Figure 1, attaching parts 103 is closely linked with pedestal 102 bottoms.Attaching parts 103 has projection 1030 to embed in the pedestal 102, strengthens binding force.
Shell 101 is to be buckled on the pedestal 102 basically.Attaching parts 103 extends to the root edge 1010 of shell 101, adopts technique for rolling not have Machining Technology for Cutting between shell 101 and the attaching parts 103, and actv. improves the inherence and the surface quality of workpiece, encloses in the root edge 1010 peripheral formation one of shell and closes up 1034.By the inside pressure of technique for rolling, can prevent effectively that shell 101 from coming off, thereby the effect of protection module is played in the inefficacy of prevention module.
Attaching parts 103 has an O-ring taper pipe thread section 1032, is connected with using the O-ring taper pipe thread between wheel hub, can guarantee that product is connected with the effective of vehicle.
In one embodiment, the specification of O-ring taper pipe thread is 3/4-14NPT.
In one embodiment, the material of shell 101 is PA66+30%GF, i.e. nylon 66+30% glass, and basic wall thickness is 2.5mm.The material of pedestal 102 is PA66+30%GF, and according to the intensity needs, pedestal 102 adopts local thickening principle, guarantees product strength and fit dimension.In one embodiment, the material of attaching parts 103 is 6061 aluminium.Preferably, material surface can be through anodic oxidation treatment.
In one embodiment, adopt Shooting Technique between pedestal 102 and the attaching parts 103, attaching parts 103 is embedded in the pedestal 102, the two uses the intensity of injection moulding inserts technology assurance product can not broken through by client's tyre inner pressure.
Fig. 3 illustrates external tire pressure detection module 100 and local figure of being connected of wheel hub 200.Fig. 4 is the A-A cutaway view of Fig. 3.In Fig. 3, wheel hub 200 is the wheel hub of engineering truck.Shown in Figure 4 in conjunction with reference, external tire pressure detection module 100 is the O-ring taper pipe thread with the employing of wheel hub 200 ways of connecting.Before the connection, on wheel hub 200, form perforate 202 in advance, and to its processing, to cooperate the O-ring taper pipe thread of external tire pressure detection module 100.
Adopt the connection mode of taper pipe thread to prevent that tire flat and product from coming off by actv..In one embodiment, O-ring taper pipe thread specification is 3/4-14NPT.
Because external tire pressure detection module 100 directly links to each other with wheel hub 200, inside tires gas acts directly on the module 100, compare other tire pressure testing product at present, the gas transmission distance can be effectively shortened in this design, and guarantees the accuracy of product measurement temperature and pressure.
In addition, compare with other products, the O-ring taper pipe thread that embodiment of the present utility model adopts is convenient to dismounting, is effectively prevented to leak gas.
Moreover the technology that external tire pressure detection module of the present utility model uses between each part is for example used technique for rolling between shell 101 and the attaching parts 103, makes the anti-shake performance of product improve greatly, can not come off; The injection moulding inserts technology of using between pedestal 102 and the attaching parts 103 makes the sealing property of product improve greatly, and anti-shake performance is also strengthened greatly.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
