Detailed description of the invention
Referring to figs. 1 through Fig. 7, a kind of back mirror embodiment of the utility model is described further.
A kind of back mirror, comprise picture frame 1, eyeglass 2, described eyeglass 2 is positioned at picture frame 1, actuating device is provided with in described picture frame 1, described actuating device comprises impeller 5, described impeller 5 is positioned at the lateral wall of picture frame 1 away from eyeglass 2, the center of described impeller 5 is provided with transmission shaft 3, described transmission shaft 3 is through the sidewall of picture frame 1, one end that described transmission shaft 3 is positioned at picture frame 1 is provided with connecting rod 4, one end of described connecting rod 4 is fixedly connected with transmission shaft 3 one end away from impeller 5, sidewall away from impeller 5 on described connecting rod 4 is provided with conflict block 6, 2 opposing sidewalls of described picture frame 1 are equipped with chute 7, slide bar 8 is provided with in described picture frame 1, described slide bar 8 coordinates with chute 7 near the two ends of chute 7, side and the conflict block 6 of described slide bar 8 are conflicted, pull back spring 9 is provided with in described picture frame 1, one end of described pull back spring 9 is fixedly connected with the sidewall of slide bar 8, picture frame 1 madial wall that the other end of described pull back spring 9 is vertical with slide bar 8 length direction is fixedly connected with, described eyeglass 2 is positioned at the side of slide bar 8 away from impeller 5, the sidewall that eyeglass 2 is vertical with chute 7 length is fixedly connected with picture frame 1 sidewall, described slide bar 8 is provided with scraping blade 11, pipe link 12, described scraping blade 11 is positioned at the side of eyeglass 2 away from impeller 5, described scraping blade 11 is fixedly connected with slide bar 8 by pipe link 12, described scraping blade 11 is provided with scraping article 13 near the sidewall of eyeglass 2, scraping article 13 is consistent with the width of eyeglass 2 along the length of slide bar 8, make scraping article 13 can clear away dirt in eyeglass 2 lateral extent, described scraping article 13 is made up of PVC material, PVC material is widely used in and makes windscreen wiper bar 13, the partially soft dirt can effectively removed on eyeglass 2 of PVC material, described scraping article 13 is inconsistent with eyeglass 2.
The length of connecting rod 4 preferably equals the half of eyeglass 2 length, make connecting rod 4 in rotary course, make scraping blade 11 can clear away dirt in the scope of eyeglass 2, back mirror is installed onboard, impeller 5 on back mirror is towards the service direction of vehicle, in the process that vehicle travels, the drive of wind-force makes impeller 5 rotate, adopt wind-force as power, effectively can save electric power resource, more meet the requirement of environmental protection, the rotation of impeller 5 can drive transmission shaft 3 to rotate, thus connecting rod 4 is rotated, conflict block 6 on connecting rod 4 can rotate around the axle center of transmission shaft 3, the sidewall of slide bar 8 can be always inconsistent with conflict block 6, pull back spring 9 is connected with between the madial wall of conflict block 6 and picture frame 1, pull back spring 9 can haul conflict block 6 always and move in chute 7, being positioned at eyeglass 2 also can up-and-down movement thereupon away from the scraping blade 11 of impeller 5 side, the scraping article 13 inconsistent with eyeglass 2 on scraping blade 11 will be clean the dirt removal on eyeglass 2, thus make vehicle in motion process, the eyeglass 2 surface moment remains totally, improve the safety in driving process.
Described actuating device also comprises driven wheel 14, reducing gear 10, one end that described driven wheel 14 and transmission shaft 3 are positioned at picture frame 1 is fixedly connected with, described reducing gear 10 rotates hinged with the madial wall of picture frame 1, described reducing gear 10 coordinates with driven wheel 14, the diameter of described reducing gear 10 is much larger than the diameter of driven wheel 14, what effectively can lower scraping blade 11 on the one hand scrapes dynamic frequency, another aspect is greater than the diameter of driven wheel 14 because of reducing gear 10 and the flank of tooth of the flank of tooth of reducing gear 10 and driven wheel 14 is suitable, the moment of rotation that the moment that impeller 5 can be made to export passes to reducing gear 10 strengthens greatly, scraping blade 11 is made more effectively to hang dynamic on eyeglass 2 surface, improve the cleaning efficiency of eyeglass 2, described connecting rod 4 is fixedly connected with the side of reducing gear 10 away from impeller 5.
Described conflict block 6 is cylindrical piece, conflict block 6 is around in centre of gration rotary course, circumferential side wall and slide bar 8 moment conflict with circumferential side wall, stability when conflicting can be strengthened, side and the connecting rod 4 of the close reducing gear 10 of described conflict block 6 rotate hinged, can rotate around jointed shaft in process when conflict block 6 and slide bar 8 are conflicted, thus avoid conflict block 6 and the slip on slide bar 8 surface, greatly reduce the friction force between conflict block 6 and slide bar 8.
The quantity of described pull back spring 9 is 2, and described 2 pull back springs 9 lay respectively at slide bar 8 and can give near the two ends of chute 7 slide bar 8 two ends identical pulling force, stably can promote slide bar 8 and slide in chute 7.
In specific implementation process, back mirror is installed in after on vehicle, in the process that vehicle travels, impeller 5 on back mirror can rotate because of the impact of wind-force, impeller 5 drive the driven wheel 14 in picture frame 1 to rotate by transmission shaft 3, the engagement of driven wheel 14 and reducing gear 10, reducing gear 10 is rotated, whipping is there is in connecting rod 4 along with the rotation of reducing gear 10, conflict block 6 is conflicted with slide bar 8 always, when pull back spring 9 is stretched to the longest, scraping article 13 is positioned near the attachment point of pull back spring 9 with picture frame 1 sidewall, when pull back spring 9 is stretched to the most in short-term, scraping article 13 is positioned at away from the attachment point of pull back spring 9 with picture frame 1 sidewall, now scraping article 13 constantly moves on the surface of eyeglass 2, thus eyeglass 2 surface is remain totally always.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
