Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides an automatic lens cleaning device for an exterior rearview mirror, which is mainly applied to an automobile and mainly comprises an exterior wiper mechanism and a cleaning liquid spraying mechanism.

Referring to fig. 3, the external wiper mechanism includes a wiper arm 12 disposed on an outer surface of the lens 8 of the external rear view mirror and a driving unit disposed inside the mirror housing 6 of the external rear view mirror.

In particular, the scraping arm 12 is "L" shaped, and the scraping arm 12 is composed of two relatively vertical parts, specifically an upper part and a side part. The bending angle of the scraping arm 12 is close to any top corner of the outer rear view mirror (this embodiment takes the top corner of the inner side of the outer rear view mirror as an example), so that the scraping arm 12 can cover the maximum area when moving.

The lower surface of the scraping arm 12 is provided with a wiper blade 11, the wiper blade 11 is made of rubber materials, the shape of the wiper blade 11 is similar to that of the scraping arm 12, the wiper blade is L-shaped and elastic, and therefore the wiper blade 11 can be better attached to the outer surface of the lens 8 and has acting force (which is very small), and the lens 8 can be scrubbed.

The upper surface of the scraping arm 12 is provided with a scraping arm cover plate 13, the shape of the scraping arm cover plate is similar to that of the scraping arm 12, the scraping arm cover plate 13 is L-shaped, so that the scraping arm cover plate 13 can protect the internal structure of the scraping arm 12, and the upper end of the scraping arm 12 is connected with the output end of the driving unit.

Referring to fig. 4, the driving unit is a motor 14 fixed inside the mirror housing 6, a lens supporting plate 16 is arranged inside the mirror housing 6, the lens supporting plate 16 is arranged on the inner surface of the lens 8 and supports the lens 8, a motor shaft 15 of the motor 14 sequentially penetrates through the lens supporting plate 16, the lens 8, the upper end of the scraping arm 12 and is connected with a fastener 18 (which may be a nut, a bolt, etc.), a rubber pad 17 is fixedly connected to a portion of the lens 8 penetrated by the motor shaft 15, and the rubber pad 17 is in an "i" shape, so that the lens 8 can be prevented from being damaged by the motor shaft 15.

Scrape arm 12 upper end and be close to the cylindrical boss 19 that the diameter reduces is stretched out to the part of lens 8, the lower extreme top of cylindrical boss 19 is in the upper surface of lens layer board 16 makes the ladder face of cylindrical boss 19 with leave the clearance between the rubber pad 17 upper end, can avoid fastening like this fastener 18 (can be nut, bolt etc.), it is in to scrape arm 12 direct pressure on the lens 8, causes lens 8 damages.

The motor shaft 17 is a stepped shaft with a diameter decreasing in a direction away from the motor 14, and the lower surface of the lens supporting plate 16 abuts on the stepped surface of the motor shaft 15, so that the lens supporting plate 16 is prevented from moving downward when the fastening member 18 (which may be a nut or a bolt) is fastened.

The part of the lens supporting plate 16 penetrated by the motor shaft 15 is provided with an outward concave cambered surface 20, so that a containing space is provided for the lower end of the rubber pad 17.

Referring to fig. 1, the cleaning liquid spraying mechanism is composed of a washing motor pump 1, a washing kettle 2 and a nozzle 7. Washing motor pump 1 wash kettle 2 fixed mounting is in the front cabin of whole car, wash kettle 2 is used for storing the washing liquid, the pump of washing motor pump 1 is gone into the pump and is held and connect wash kettle 2, pump output end pass through leading water pipe 3 and connect nozzle 7. The nozzle 7 is mounted inside the mirror housing 6 of the exterior rear view mirror, and the front end thereof penetrates through the mirror housing 6 of the exterior rear view mirror and faces the lens 8 of the exterior rear view mirror.

In addition, in order to clean the two outer rearview mirrors of the vehicle, the number of the outer wiper mechanisms in the automatic lens cleaning device for the outer rearview mirrors is set to two, the two outer wiper mechanisms are respectively arranged on the two outer rearview mirrors, and the two outer wiper mechanisms are both installed according to the installation and fixed connection mode, so that repeated explanation is not needed.

Simultaneously each all be equipped with two at least nozzles 7 on the outside rear-view mirror, the quantity of nozzle 7 can set up as required. Specifically, the water conduit 3 is provided with a first three-way valve 4, and the cleaning liquid is distributed to the nozzles 7 on the two external rear-view mirrors through the first three-way valve 4, so that the cleaning liquid can be sprayed on the surfaces of the lenses 8 of the two external rear-view mirrors.

When the number of the nozzles 7 on the surface of each external rear-view mirror is two, the two nozzles 7 are respectively connected with two interfaces of the second three-way valve 5 through pipelines, and the other interface of the second three-way valve 5 is connected with one interface of the first three-way valve 4 through a pipeline, so that the cleaning liquid can be conveyed to each external rear-view mirror.

Referring to fig. 2 and 3, the two nozzles 7 on the surface of each outer mirror are respectively located at the upper end of the middle point of the upper portion of the scraping arm 12 and outside the middle point of the side portion, so as to ensure that the two nozzles 7 are reasonably spaced and the spraying range of the cleaning solution is wide, and as described above, the bending angle of the scraping arm 12 is located at any top angle of the outer mirror and the scraping range is wide, so that the cleaning solution sprayed by the two nozzles 7 can cover the movement range of the wiper blade 11, so as to meet the requirement GB/15084-.

Referring to fig. 1, the washing motor pump 1 and the motor 14 are connected to an automobile power supply through a wire harness 9, and a switch 10 is disposed on the wire harness 9, so that the switch 10 can simultaneously control the start and stop of the washing motor pump 1 and the motor 14.
