Description
Technical field
The invention belongs to vehicle component technical field, be specifically related to a kind of visual expansion device of vehicle mirrors.
Background technology
Known reason, the function of vehicle mirrors is the situation of reflection automobile rear, side and below, helps driver indirectly to watch the situation of these positions, to ensure safety, in view of this, vehicle mirrors is likened to " second eye " that help driver to broaden one's vision by people.But, in the use procedure of reality, namely vehicle is in traveling and parking process, cannot reflect outside vehicle front-wheel and the blind area in region, front-wheel dead ahead because back mirror exists, thus entirely to judge with the experience of self with driver, use avoid vehicle side front bumper/spoiler, fender guard, wheel tire and wheel rim and foreign matter or claim obstacle to swipe.The understanding that can obtain specifically by the signal of Fig. 4 to this, Fig. 4 shows and is arranged on vehicle according to common practise and corresponds to the vehicle mirrors body 1 of operator's compartment side and opposite side, and show aforesaid blind area 10, because this blind area 10 is difficult to even vehicle mirrors body 1 to be relied in operator's compartment to observe by chaufeur, thus there is the bumper/spoiler in front, aforesaid side, fender guard, the anxiety of the tire of wheel and wheel rim and obstacle collision, especially owe for driving experience the person of enriching, vehicle damage and even accidents caused is caused because of error in judgement.
Around being intended to solve the problems of the technologies described above, corresponding technical scheme can be seen in disclosed patent documentation, as Authorization Notice No. CN2584459Y recommendation has " automobile rear view mirror without dead zone ", this patent formula installs a small-sized convex mirror additional in the gluing mode connect of the top AB of vehicle mirrors body, and the radius of curvature of convex mirror is designed to 40-50 ㎜.The famous shortcoming that can make up Chinese patent ZL90205503.8, ZL91203189.1 and ZL95205332.2 of this patent formula, but from description and the graphic structure of its description, this back mirror installed additional does not have the function reflecting aforementioned blind area, and only serves the minute surface expanded function to back mirror.Again, Authorization Notice No. CN201712539U provides " automobile rearview mirror ", because this patent formula is provided with an additional mirror by mirror pedestal and flexible pipe in the bottom of vehicle mirrors body, what thus there is aforementioned CN2584459Y equally does not have the function reflecting described blind area.
In view of above-mentioned prior art, be necessary rational modification in addition, the applicant has done useful design for this reason, finally defines technical scheme described below, and proves practicable through applicant taking the analogue test under secrecy provision.
