Specific embodiment
Following embodiment only exists in illustrative purpose, limits the scope of the invention without being intended to.
Embodiment 1
As shown in Figs. 1-2, the vehicle-mounted backup camera of a kind of self-cleaning, including shell 1 and camera body 2, camera sheet
Body 2 is mounted in shell 1, and camera body 2 is externally provided with horizontally disposed transparent circular cowling 3, and transparent circular cowling 3 can be used transparent
Glass material, the side wall of shell 1 are equipped with the camera shooting mouth 4 to match with transparent circular cowling 3, camera shooting mouth 4 and camera body 2
Position is corresponding, and keeps identical radian with the lateral wall of transparent circular cowling 3 on the side wall of camera shooting mouth 4, to improve transparent ring
Sealing effect between shape cover 3 and camera shooting mouth 4 is rotatably connected to the more limits for limiting to transparent circular cowling 3 in shell 1
Axis 5, the quantity of limit shaft 5 are four, and four limit shafts 5 are distributed about the center of circle rotational symmetry of transparent circular cowling 3, transparent ring
Cleaning cotton 6 is filled between 1 inner sidewall of 3 lateral wall of shape cover and shell, absorbent cotton material can be used in cleaning cotton 6, before use, logical
It crosses cleaning solution to soak cleaning cotton 6, it should be noted that the frictional force between cleaning cotton 6 and transparent circular cowling 3 is negligible not
Meter.
In the present embodiment, the interior of transparent circular cowling 3 is equipped with friction pulley 7, the inner sidewall phase of friction pulley 7 and transparent circular cowling 3
Contact, friction pulley 7 can be used rubber material, on the one hand can reduce the loss to transparent circular cowling 3, on the other hand can provide
Stronger frictional force has been fixedly and coaxially connected shaft 8 on friction pulley 7, and the upper end of shaft 8 is fixedly connected with the inner top surface of shell 1,
The lower end of shaft 8 is through shell 1 and is fixedly connected with Pneumatic wheel 9, and the downside of automobile chassis is arranged in Pneumatic wheel 9, keeps vehicle bottom fast
The air-flow of speed flowing can drive Pneumatic wheel 9 to rotate, it should be noted that Pneumatic wheel 9 can also be by from locking-type telescopic rod
It is fixedly connected with (not shown go out) with shaft 8, the position of Pneumatic wheel 9 can be adjusted, facilitates according to different vehicle progress
Adjustment.
In the present embodiment, in motion, the air-flow that vehicle bottom is quickly flowed can blow the rotation of Pneumatic wheel 9,9 band of Pneumatic wheel to automobile
Turn axis 8 rotates, and shaft 8 drives friction pulley 7 to rotate, and friction pulley 7 drives annular transparent cover 3 to rotate, in the effect of cleaning cotton 6
Under, annular transparent cover 3 in the course of rotation can clean the lateral wall of itself, and transparent circular cowling 3 is made to be located at camera shooting
The position of mouth 4 keeps clean, and camera body 2 is made to keep clearly collection effect.
Embodiment 2
As shown in Figure 3-4, the present embodiment difference from example 1 is that: it is fixed that the two sides of transparent circular cowling 3 are equipped with
Position axis 10, the upper and lower ends of locating shaft 10 are rotatablely connected with the inner sidewall up and down of shell 1 respectively, are passed through between two locating shafts 10
Cleaning band 11 is sequentially connected, and cleaning band 11 can be used hygroscopicity fibre and be made, and rubbing between cleaning band 11 and transparent circular cowling 3
The frictional force that power is less than between friction pulley 7 and transparent circular cowling 3 is wiped, wherein a locating shaft 10 passes through transmission mechanism and shaft 8
Transmission connection is coaxially consolidated on locating shaft 10 specifically, transmission mechanism includes the first gear 12 being fixedly and coaxially connected with shaft 8
Surely it is connected with second gear 13, third gear 14, third gear 14 and shell are engaged between first gear 12 and second gear 13
The inner bottom surface of body 1 is rotatablely connected.
In the present embodiment, it will drive first gear 12 when Pneumatic wheel 9 rotates and rotate, first gear 12 passes through third gear
14 drive second gears 13 rotate simultaneously, rotate synchronously transparent circular cowling 3 and cleaning band 11, and the rotation direction of the two
On the contrary, the relative displacement between cleaning band 11 and transparent circular cowling 3 can be greatly increased, transparent circular cowling 3 is played preferably
Cleaning effect, at the same time, cleaning band 11 in the course of rotation, are contacted with cleaning cotton 6, can be realized the cleaning to itself,
Further increase the cleaning effect to transparent circular cowling 3.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
