Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, it can be seen from the figure that the reversing camera and the rear license plate cleaning device of the present invention include a washing pot 1 containing washing liquid, a washing pump is arranged in the washing pot, the washing pump is connected with a washing motor, and the washing pump passes through The water delivery pipe 2 is connected to the nozzle 3. The back door sheet metal 11 is provided with a shower head access hole, and the shower head is connected with a drive mechanism so that the shower head can enter and exit the shower head access hole. A back door trim 12 is installed on the back door sheet metal 11, a rear license plate 5 is installed on the back door sheet metal 11, a reversing camera 4 is arranged on the back door trim 12, and the water outlet hole on the nozzle is located on the nozzle. Stretch out the shower nozzle access hole and face the reversing camera 4 or/and the rear license plate 5 when it is in the working position.

The end of the nozzle 3 is provided with a cover plate 6, the cover plate 6 is larger than the inlet and outlet holes of the nozzle to cover the inlet and outlet holes of the nozzle, so that when the nozzle is retracted, the cover plate just covers the inlet and outlet holes of the nozzle, and the cover plate can also be used as a baffle , to avoid spraying water from the nozzle.

The driving mechanism can have various structures, as long as the nozzle can be stretched out when the cleaning instruction is issued, and can be automatically retracted after cleaning. As a preferred structure, the driving mechanism includes a piston barrel 7 and a piston 8 located in the piston barrel. One end of the piston barrel is provided with a water inlet, the other end is provided with a piston rod through hole, and the water delivery pipe is connected to the water inlet of the piston cylinder; There is a piston rod 9, and the other end of the piston rod 9 passes through the through hole of the piston rod and is connected with the nozzle 3. The middle part of the piston is provided with a water hole, which communicates with the water outlet hole on the nozzle through the internal channel of the piston rod. In the piston barrel 7, a nozzle return compression spring 10 is arranged on the end surface where the piston and the piston rod pass through holes. This structure simply improves the traditional piston structure, that is, a channel is added on the piston and the piston rod to communicate with the nozzle. On the one hand, the washing water can be sprayed from the nozzle through the added channel for cleaning; The high pressure pushes the piston and the nozzle connected to it to protrude. When it is not cleaned, the nozzle is automatically retracted due to the high pressure, and the cover plate just covers the nozzle inlet and outlet holes, so that the appearance of the rear of the vehicle is the same as that of the existing vehicle under normal conditions. Visible structural increase.

In the specific vehicle design, in addition to adding the above-mentioned reversing camera and rear license plate cleaning device, it is also necessary to install a reversing camera and a rear license plate cleaning switch in the car (such as the center console area). The motor connections form a loop.

When cleaning is required, press the reversing camera and the rear license plate cleaning switch, the washing motor is connected, the washing pump starts to work under the drive of the motor, and the washing water is sprayed once. The washing water is high-pressure water, and the high-pressure water enters the piston barrel and acts On the piston, push the piston to move against the pressure of the compression spring, so that the nozzle fixed with the piston protrudes from the inlet and outlet holes of the nozzle and reaches the working position. At the same time, the washing water enters the nozzle through the water hole in the middle of the piston and the internal channel of the piston rod in turn, and is sprayed out from the water outlet hole on the nozzle, thereby cleaning the reversing camera and the rear license plate. If one cleaning is not enough, you can repeatedly press the cleaning switch. When cleaning is no longer done once, there is no high-pressure water in the piston barrel. At this time, the piston rod drives the nozzle to retract under the action of the rebound force of the compression spring. When retracting, the cover plate on the nozzle just in time covers the nozzle inlet and outlet holes.

Of course, if the vehicle does not have a reversing camera, just adjust the nozzle to align with the rear license plate. If the vehicle is not equipped with a reversing camera but a reversing radar, it can also be cleaned based on the same structure.
