The utility model has the following advantages and beneficial effect compared to existing technology:
When the utility model is locked by unlock switch, the elastic force precompressed of spring makes the engagement of the first gear and the second gear, produce axial coupling mechanism force, avoid the sun visor body driving process or run into while jolting swinging, rotating shaft can coordinate by firm locking with sun shield, improves the safety of driving; After the unlock switch release, the second gear of controlling on the unlock switch end face by unlock switch separates with the first gear, reaches the purpose of release, improves the simplicity of operation.
The accompanying drawing explanation
The perspective view that Fig. 1 is the present embodiment;
The decomposition texture schematic diagram is amplified in the part that Fig. 2 is the A part in Fig. 1;
Fig. 3 is the sectional structure schematic diagram along the B-B line of Fig. 1.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figures 1 and 2, the present embodiment provides a kind of axial locking mechanism of automotive sunshade panel, comprises the sun visor body 2 that is movably connected in roof position in automobile by rotating shaft 1, and an end of described rotating shaft 1 is connected with the first gear 3; Described sun visor body 2 is provided with unlock switch 4, described unlock switch 4 one ends are provided with spring 5, the other end of unlock switch 4 is provided with the second gear 6, described the first gear 3 and the second gear 6 rotating shaft 1 axially on over against setting, wherein, described spring 5 compression sets drive the second gear 6 and described the first gear 3 engagements during 4 locking of described unlock switch, during described unlock switch 4 release, unlock switch 4 drives described spring 5 compression sets and drives the second gear 6 and separates with the first gear 3.
As shown in Figure 3, the extension 8 that described unlock switch 4 comprises circle section 7 and is arranged on projection on the outer wall of circle section 7, described sun visor body 2 has square through hole 9 on the correspondence position with extension 8, described square through hole 9 is pegged graft and is coordinated with extension 8, and it is interior along space mobile on the axial direction of rotating shaft at square through hole 9 that described square through hole 9 is provided with described extension 8.
