Description
Technical field
The invention belongs to car electrics field, refer to especially a kind of automotive diagnosis interface fixed sturcture that is fixed on electrical appliance kit body.
Background technology
Along with the development of automotive technology, automobile information, intelligent degree are more and more higher, when automobile breaks down, need to pass through diagnosis interface, and external automobile dedicated diagnostic device is that car load carries out trouble diagnosing.
Automotive diagnosis interface is that state III discharges the indispensable interface of above car load, and car load diagnosis interface fixed form is that vehicle body sheet metal tapping bolt nut type is fixed or is directly tied on wire harness substantially in the market.Automotive diagnosis interface card is substantially realized universalization in each vehicle, and the diagnosis interface plug-in unit model of different brands is the same, but is limited to the difference of different automobile types car load structure, and the position that diagnosis interface is arranged on car load is different.
At present, the miniaturization of vehicle, multifunction become a kind of trend day by day, and vehicle greater functionality just needs more arrangement space, and for car load, to save space more and more important.Car load light-weight design becomes a kind of trend, is conducive to energy resource saving.
The diagnosis interface plug-in unit of existing technology is fixed by the mode of bolt and nut, plug-in unit fixed position is generally chosen on vehicle body sheet metal, and it is 5mm hole that panel beating is opened two diameters, is limited to the difference of different automobile types vehicle body metal plate structure, diagnosis interface plug-in unit fixed position is uncertain, as shown in Figure 1.
The shortcoming of this technology is:
1. because body structure, the structure of each vehicle are different, cause diagnosis interface plug-in unit fixed position different, search difficulty.
2. because must meet easy external diagnostor, diagnosis interface plug-in unit is easily subject to the restriction of car load insufficient space, needs reserved enough spaces on panel beating, arranges that difficulty is large.
3. generally need to design special examine a patient the check to fix lid mouthful.
4. diagnosis interface has power lead, and power taking position is fuse box, and diagnosis interface plug-in unit is far away apart from the position of fuse box, and the risk of diagnosis power lead short circuit is just larger.
5. adopt the fixed form of bolt, nut, produce efficiency of assembling low, cost is high, and this kind of assembling mode need to be assembled in car assembling workshop.
Now also have another structure, diagnosis interface is bound on wire harness by band (or electric adhesive tape), and position arranges arbitrarily, as shown in Figure 2.
The shortcoming of this technology is:
1. fixedly reliability is low.
2. because wire harness is generally arranged in the inner spaces such as instrument desk, diagnosis interface plug-in unit is searched difficulty.
3. need to design special examine a patient the check to fix lid mouthful.
4. diagnosis interface has power lead, and the fixed form safety that diagnosis interface plug-in unit is bound on wire harness is not good enough.
Summary of the invention
The object of the invention is in order to address the above problem, the invention provides a kind of new-type diagnosis interface plug-in unit fixed sturcture designing on electrical appliance kit body, apply this structure, diagnosis interface plug-in unit is fixing safe and reliable, save space, and diagnosis interface fixed position is easily unified, be not subject to the restriction of complete vehicle structure, arrangement space, car load is without customized design examine a patient the check to fix lid mouthful, and wire harness is safe and reliable, easy to assembly, produce that efficiency of assembling is high, integrated cost is low.
