The flexible axle tooth bar loop structure of power sunroof
Technical field
This utility model relates to power sunroof;
Particularly relate to the flexible axle tooth bar loop structure of a kind of power sunroof.
Background technology
Along with the raising of people's living standard, the consumption of automobile is also got more and more by people, one of automobile important vehicles having become as people, and this market of auto parts machinery becomes the most increasing.In the last few years auto parts machinery manufacture factory also in performance at full speed at that, auto parts machinery of a great variety, including engine fittings, power train accessory, braking system accessory, steering system accessory, running gear accessory, hang class accessory, igniting is accessory, Fuel System accessory, cooling system accessory, lube system accessory, electrical instrumentation system accessory, Switch accessory, air-conditioning class accessory, sensor accessory and other class accessories etc..
Skylight is also the one in auto parts machinery, it is fitted with power sunroof in the market on the roof of a lot of commercial SUV, car, power sunroof drives skylight glass and abat vent by flexible axle tooth bar in the cooperation with motor gear, in place of the loop structure of flexible axle tooth bar comes with some shortcomings in structure design at present: refering to shown in Fig. 1, most of skylights of the prior art design all uses plastic tube as the return of flexible axle tooth bar and to be arranged in the rear rhone back side, causing with interior body trim roof liner apart from short, interior space is narrow and small;Meanwhile, plastic catheter is arranged in the rear rhone back side, due to plastic catheter turning radius too small and when causing flexible axle tooth bar to move back and forth in plastic catheter resistance big, there is defect easy to wear, that noise is big.And plastic tube can increase product cost.
Utility model content
All deficiencies of prior art in view of the above, the technical problems to be solved in the utility model is to provide the flexible axle tooth bar loop structure of a kind of power sunroof, to overcome the drawbacks described above of prior art.
For achieving the above object and other relevant purposes, this utility model provides the flexible axle tooth bar loop structure of a kind of power sunroof, described flexible axle tooth bar loop engages to drive skylight glass and abat vent with driving gear, driving gear is located at behind skylight on rhone, driven gear is located in the guide rail of skylight, and two sections of flexible axle tooth bars connect driving gear and driven gear composition flexible axle tooth bar loop.
The flexible axle section of rack being preferably located in the guide rail of described skylight is integrated in the wind screen region of skylight guide rail.
Preferably, it is provided with the gathering sill for spacing flexible axle tooth bar in the guide rail of described skylight.
Preferably, the three/two-stage nitration in described flexible axle tooth bar loop is positioned at skylight guide rail.
By above technical scheme, compared to prior art, this utility model has following technical effect that the major part of flexible axle tooth bar is integrated in the guide rail of skylight by this utility model, eliminate traditional design plastic catheter, reduce cost and SR, it assembles also operation and reduces the most accordingly, reduces the risk producing noise simultaneously, and makes skylight structure more compact, flexible arrangement is higher, possesses high industrial utilization.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be understood other advantages of the present utility model and effect easily by the content disclosed by this specification.
Refer to Fig. 1 to Fig. 4.Notice, structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to coordinate the content disclosed in description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still fall in the range of the technology contents disclosed in this utility model obtains and can contain.Simultaneously, in this specification cited as " on ", D score, "left", "right", the term of " middle " and " " etc., it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, being altered or modified of its relativeness, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
Refering to shown in Fig. 2, Fig. 3 and Fig. 4, this utility model provides the flexible axle tooth bar loop structure of a kind of power sunroof, flexible axle tooth bar loop engages to drive skylight glass and abat vent with driving gear 3, driving gear is located at behind skylight on rhone 1, driven gear is located in skylight guide rail 4, two sections of flexible axle tooth bars 2 connect driving gear and driven gear composition flexible axle tooth bar loop, and the three/two-stage nitration in flexible axle tooth bar loop is positioned at skylight guide rail.The major part of flexible axle tooth bar is integrated in the guide rail of skylight by this utility model, smooth the moving in the guide rail of skylight of flexible axle tooth bar, does not have large curved, eliminates traditional design plastic catheter, reduces cost and SR, and it assembles also operation and reduces the most accordingly.And the flexible axle section of rack being positioned at skylight guide rail is integrated in the wind screen region of skylight guide rail, do not interfere with and vehicle body sheet metal and the gap of interior body trim roof liner, the noise problem avoiding automobile skylight when jolting road conditions vibrations little with vehicle body gap and to produce, reduce the risk producing noise, SR is less, and reliability is higher.
As further improvement of the utility model, being provided with the gathering sill for spacing flexible axle tooth bar and make skylight structure more compact in skylight guide rail 4, flexible arrangement is higher.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting this utility model.Above-described embodiment all can be modified under spirit and the scope of the present utility model or change by any person skilled in the art.Therefore, art has all equivalence modification or changes that usually intellectual is completed under without departing from the spirit disclosed in this utility model and technological thought such as, must be contained by claim of the present utility model.
