Description

A kind of automobile-used outside rear-view mirror with high verticality rotating shaft

Technical field

The utility model relates to a kind of automobile-used outside rear-view mirror, specifically is a kind of rotating shaft with high verticality, reduces the potential safety hazard of eyeglass shake in the driving process, and the low automobile-used outside rear-view mirror of productive costs.

Background technology

Outside rear-view mirror is an indispensable accessory in the vehicle, and it mainly act as the field range that makes things convenient for chaufeur can observe laws and regulations requirement by back mirror in car, and outside rear-view mirror will guarantee that when driving imaging is clear, thereby guarantees the safety of driving.In the prior art structure of outside rear-view mirror commonly used as shown in Figure 1, 2, it has comprised 1-mirror holder component (eyeglass and mirror holder are by the integral body of the bonding formation of rupture pressure disc), 2-eyeglass adjusting movement, 3-substrate, 4-mirror shell, 5-face shield, 6-Triangulum, the 7-rotating shaft, 8-stage clip, nine parts of 9-back-up ring; Wherein, link to each other by buckle structure between mirror holder component 1 and the movement 2, movement 2 and substrate 3 link to each other by screw, substrate 3, rotating shaft 7, stage clip 8 and back-up ring 9 link together, substrate 3 and mirror shell 4 are connected by screw, Triangulum 6 also is to link together by screw with rotating shaft 7, so just finishes the assembling of whole back mirror.

The rotating shaft of the outside rear-view mirror in the technology now comprises similar hollow cylinder (shaft part is less it on, time shaft part is bigger), and the lower surface of this hollow cylinder is provided with and is used to connect Triangulum, block that volume is bigger; The stress concentration of the root of the hollow cylinder of the rotating shaft of axle because conduct collapses, outside rear-view mirror the phenomenon of rotating shaft root fracture often occurs when collapsing; Therefore in order to guarantee the intensity of rotating shaft, usually adopt diecasting (aluminum alloy or zinc alloy), yet adopt diecasting that cost is risen, and be subjected to the influence of die casting and extrusion process again easily, make the squareness of rotating shaft not meet the demands, influence vibration performance, to such an extent as to influence the traffic safety of chaufeur.In addition, the structure of the rotating shaft of the outside rear-view mirror of the different model of Chu Shouing differs bigger in the market, i.e. the rotating shaft of each model can only be used for the back mirror of same model, and commonality is poor; When researching and developing new outside rear-view mirror, need to research and develop the new rotating shaft that is mated simultaneously, increased the cost of development of new product.

The utility model content

The technical problems to be solved in the utility model provides a kind of rotating shaft with high verticality, reduces the potential safety hazard of eyeglass shake in the driving process, and the low automobile-used outside rear-view mirror of productive costs.

The technical problems to be solved in the utility model, can realize by following technical scheme: a kind of automobile-used outside rear-view mirror with high verticality rotating shaft, comprise substrate, Triangulum, rotating shaft, stage clip and mirror shell, wherein, the described rotating shaft of described stage clip ring set, described mirror shell and described substrate are fixedly linked, and described rotating shaft links to each other with the Triangulum that is positioned at described substrate below after passing described substrate, and it is characterized in that: the lower surface of described rotating shaft is provided with a plurality of boss that have than small area of contact; Have a plurality of breach suitable with the boss of described rotating shaft on the described Triangulum, the boss of described rotating shaft is buckled in described Trianguli lower surface by above-mentioned breach.

Because the rotating shaft of this outside rear-view mirror connects Triangulum by the boss that is arranged on its lower surface, and the influence of the total of boss countershaft is little, concentrated stress is also little, can prevent effectively that rotating shaft from fractureing when outside rear-view mirror collapses; Simultaneously,, during fabrication, need not to adopt preesure-poured method, avoid the squareness of rotating shaft to be subjected to the influence of die casting and die casting instrument, thereby obtain the rotating shaft of high verticality because the structure of this rotating shaft has improved the intensity of self.

Described rotating shaft comprises and is barrel-contoured shaft part and the following shaft part gone up, and the described shaft part of going up is the loudspeaker tubular that shrinks from top to bottom, and the length of described length that goes up shaft part and described stage clip is suitable, described under shaft part be cylindric.The last shaft part of rotating shaft is arranged to the loudspeaker tubular, is to make the mould that needs for convenience, reduces the difficulty and the manufacturing cost of processing.
