[0015] Working principle: When cleaning the windows of new energy vehicles, the connecting rod is lifted in coordination with the slider connected to it and the top of the telescopic airbag under the push of the electric push rod 2, so that the telescopic airbag is initially stretched and inhaled. The slider drives the connecting gear to disengage from between the two gears 2, and the frame connected to the top side of the telescopic airbag is lifted synchronously, and the nozzle inside the frame is lifted, and the baffle is lifted to expose the frame to the outside. During the displacement of the frame, the gear 1 connected to the valve ball is rotated through the rack 2 connected to it, so that the opening of the valve ball is turned, thereby changing the direction of the subsequent guided air flow, and then the electric push rod 2 is used to move the gear 1 connected to the valve ball. The push rod pushes the telescopic airbag to compress the telescopic airbag, and the air is transported to the nozzle through the connected hose and the reversing valve. The cleaning liquid in the liquid storage box is transported to the nozzle along the hose, so that the cleaning liquid mixed with the air is pressurized and sprayed out, thereby spraying the cleaning liquid on the surface of the car window. During the pushing process of the electric push rod, the bottom end of the telescopic airbag will also drive the rack to mesh, and the meshing transmission of the rack drives the gear two on the right end to rotate, so that the rotating wheel connected to the gear two on the right end drives the nozzle connected through the telescopic rod and the curved rod to rotate, thereby changing the spraying position of the nozzle to cover a larger spraying area. After the spraying of the cleaning liquid is completed, the electric push rod 2 will first pull the connecting rod down, thereby resetting the slider and the top of the telescopic airbag connected thereto, the reversing valve is closed, and the slider drives the connecting gear back between the two gears 2. Then the electric push rod 2 pulls the bottom end of the telescopic airbag together with the rack 1 to move downward a certain distance, engaging the gear 2 on the right end of the transmission. While the nozzle is reset, the gear 2 on the right end will also transmit the gear 2 on the left end through the connecting gear, thereby causing the trigger wheel connected to the gear 2 on the left end to rotate a certain angle, so that the protrusion of the trigger wheel abuts against the right side of the slide plate, and force is applied to it along the curve, so that the slide plate is displaced to the left and the spring is compressed. The displaced slide plate will abut against the abutment protrusion of the limit shaft through the abutment protrusion, so that the limit shaft slides on the outer wall of the spline shaft and presses The compression spring causes the locking gasket of the limit shaft to disengage from the locking gasket on the rotating shaft connected to the half gear, thereby releasing the lock and allowing the half gear to rotate. Under the action of its own gravity, the car window presses down the two connecting rods, causing the two connecting rods to rotate and the angle to change, causing the car window to lose the support of the connecting rod, thereby causing the car window to drop, and the surface of the car window to be continuously in contact with the scraper, so that the surface of the car window is scraped by the scraper in coordination with the cleaning liquid, thereby scraping off the stains and achieving cleaning. After dropping to a certain height, the electric push rod drives the telescopic airbag to completely reset, and through transmission, the trigger wheel rotates again, causing the protrusion to disengage from the right side of the slide plate, and the compression reset spring pushes the slide plate to reset, thereby causing the limit shaft to drive the tightening gasket to reset, re-engage and lock the half gear, so that the car window no longer drops.

[0016] The present invention provides a new energy vehicle interior window cleaning device, which has the following beneficial effects: 1. The present invention adopts a hidden design and mounts the cleaning device inside the vehicle door, so that the nozzle for spraying the cleaning liquid can be protected. The design of the single nozzle rotating synchronously during the spraying process can expand the spraying area, reduce the number of nozzles, maximize the utilization rate of the single nozzle, and reduce the loss of cleaning liquid.

[0017] 2. The present invention adds an air-inflating and pressurizing design during the spraying process, so that the cleaning liquid can be pressurized by air during spraying and can be sprayed out with greater pressure, thereby extending the spraying distance and allowing the cleaning liquid to be sprayed over a larger area, thereby improving the spraying effect.

[0018] 3. The present invention connects the cleaning device to the lifting system of the vehicle window. After spraying, the vehicle window can be lowered and the scraper can be used to scrape the window surface with cleaning liquid to remove stains. BRIEF DESCRIPTION OF THE DRAWINGS

The cleaning liquid entering the nozzle 8 can be sprayed in a high-pressure form through the gas supply and pressurization of the telescopic airbag 3 to perform the cleaning liquid spraying work; Specifically, the nozzle of the nozzle 8 is oriented toward the vehicle window 2 so that the cleaning liquid can be sprayed on the glass of the vehicle window 2 better. The output end of the telescopic airbag 3 and the two input ends of the nozzle 8 are both provided with a one-way valve diaphragm to prevent the gas from entraining the liquid to flow back into the telescopic airbag 3. When spraying, the electric push rod pushes the telescopic airbag 3 to compress the telescopic airbag 3, and the air is transported to the nozzle 8 through the connected hose and the reversing valve. The cleaning liquid in the liquid storage box 31 is transported to the nozzle 8 along the hose, so that the cleaning liquid mixed with the air is pressurized and sprayed, so that the cleaning liquid is sprayed on the surface of the vehicle window 2.

[0023] Please see attached Figure 4 , Attachment Figure 7 and attached Figure 8 The reversing valve is composed of a valve body 11 and a valve ball 12 located on the right side of the frame 9. The top side of the valve body 11 is fixedly connected to the inner wall of the door housing 1 through a bracket. The input end of the valve body 11 is connected to the output end of the telescopic airbag 3 through a hose. One of the output ends of the valve body 11 is connected to one of the input ends of the nozzle 8 through a hose. By setting two output ends, the negative pressure effect generated when the telescopic airbag 3 is evacuated can be reduced, and then one output end is selected to reduce the negative pressure effect.

When the car window 2 is lowered, it will scrape the surface of the car window 2 sprayed with cleaning liquid, and the car window 2 is vertically lifted and lowered by the lifting unit, and the lifting unit is installed and built on the fixed frame 23 at the inner left end of the car door shell 1. The rear side of the fixed frame 23 is rotatably connected with a rotating shaft 24, and the front side of the rotating shaft 24 is connected to the lifting unit, and a limited shaft 25 is arranged on the rear side of the rotating shaft 24. The interior of the limited shaft 25 is slidably connected with a spline shaft 26 through a spring, and the rear side of the spline shaft 26 is fixedly connected to the rear side of the inner wall of the car door shell 1. When the rotating shaft 24 is connected to the adjacent side of the limited shaft 25 by mutually engaged locking gaskets, the lifting unit will be locked and cannot drive the car window 2 to lift and lower, and the limited shaft 25 is horizontally slid on the outer wall of the spline shaft 26 through the abutment to release the lock; Please see attached Figure 2 and attached Fig.10 , wherein the lifting unit is mainly composed of two mutually intersecting connecting rods 21 and mutually meshing gear three 19 and half gear 20, the gear three 19 is rotatably connected to the front side of the fixed frame 23, the rear side of the gear three 19 is fixedly connected to the front side of the rotating shaft 24, the bottom side of the window 2 is fixedly connected to the sliding frame 22, the right end of the fixed frame 23 is provided with a sliding groove, the middle ends of the two mutually intersecting connecting rods 21 are connected by rotation, one end of one of the connecting rods 21 is fixedly connected to the half gear 20, the other end of one of the connecting rods 21 is slidably connected to the inside of the sliding frame 22, one end of the other connecting rod 21 is slidably connected to the inside of the sliding groove, and the other end of the other connecting rod 21 is rotatably connected to the left end of the sliding frame 22, and the gear three 19 is rotated with a motor as a driving source, and the motor is installed on the rear side of the fixed frame 23; Specifically, the electric push rod 3 and the motor are used to normally control the lifting and lowering of the vehicle window 2. The interior of the sliding frame 22 and the interior of the sliding groove are both provided with a rubber layer, so that the connecting rod 21 is subjected to a certain friction when sliding inside, thereby slowing down the rotation speed caused by the downward force of the vehicle window 2, and then slowing down the descent of the vehicle window 2.

[0025] Please see attached Figure 6 , Attachment Fig.11 and attached Fig.12 The abutment member is composed of a slide plate 27 slidably connected to the rear side of the fixing frame 23 and a trigger wheel 28 fixedly connected to the front side of another gear 2 15. A plurality of protrusions are equidistantly arranged around the periphery of the trigger wheel 28. The trigger wheel 28 is located on the right side of the slide plate 27. Abutment protrusions are arranged on the side close to the bottom end of the slide plate 27 and the limiting shaft 25. The left end of the slide plate 27 is connected to the fixing frame 23 through a spring. An electric push rod 3 is installed at the bottom end of the rear side of the fixing frame 23. The driving end of the electric push rod 3 abuts against the left end of the bottom side of the slide plate 27.

[0026] Specifically, the slide plate 27 can also be pushed by the push of the electric push rod 3 to unlock the half gear 20. At this time, the motor can be started to drive the gear 3 19 to mesh the transmission half gear 20, so that the connecting rod 21 is pulled to lift the window 2. After the cleaning liquid spraying is completed, the surface of the window 2 needs to be scraped and decontaminated. After the contact half gear 20 is locked, the window 2 presses down the two connecting rods 21 under the action of its own gravity, so that the two connecting rods 21 rotate and the angle changes, so that the window 2 loses the support of the connecting rod 21, and then the window 2 is lowered, and the surface of the window 2 is constantly in contact with the scraper 29, so that the surface of the window 2 is scraped by the scraper 29 in coordination with the cleaning liquid, thereby scraping off the stains and achieving cleaning.

[0027] Please see attached Figure 4 , Attachment Figure 6 and attached Fig. 9, gear rack 4, gear rack 4 is fixedly connected to the inner middle end of the door shell 1, and the right end of the front side of the gear rack 4 is rotatably connected to a rotating wheel 5, and a damping ring is provided on the side close to the rotating wheel 5 and the gear rack 4 to prevent the rotating wheel 5 from rotating when no external force is applied, and a telescopic rod 6 is fixedly connected to the top side of the rotating wheel 5, and the top side of the telescopic rod 6 is fixedly connected to the bottom side of the nozzle 8 through a curved rod 7, and a gear 2 15 is provided at the front end of the left side of the gear rack 4 and the front side of the rotating wheel 5, one of the gears 2 15 is fixedly connected to the front side of the rotating wheel 5, and another gear 2 15 is rotatably connected to the left end front side of the gear rack 4, and another gear 2 15 is connected to the resistance member, and the two gears A connecting gear 16 for connecting the transmission is provided on the adjacent side of the wheel 2 15. The connecting gear 16 is connected to the gear frame 4 through a sliding member. The sliding member and the telescopic airbag 3 are connected through a connecting rod 18. The sliding member is composed of a slider 17 slidably connected to the middle end of the gear frame 4. The bottom side of the connecting rod 18 is connected to the inner bottom side of the gear frame 4 through a spring. The left end of the connecting rod 18 is fixedly connected to the rear end of the slider 17, and the right end of the connecting rod 18 is fixedly connected to the rear side of the top end of the telescopic airbag 3. When the nozzle 8 is lifted by the electric push rod 2 on the bottom side, the sliding member and the frame 9 will be lifted synchronously to release the synchronous transmission of the two gears 2 15 through the connecting gear 16.

[0028] Specifically, when the connecting gear 16 is disengaged from the two gears 15, the gear 15 at the left end will rotate to a certain extent, and at the same time, the connecting gear 16 rotates freely, so that the connecting gear 16 can be disengaged from between the two gears 15, and when the connecting gear 16 is reset, it can be reset back between the two gears 15 by meshing and abutting the rotation of the left end gear 15. After the slider 17 drives the connecting gear 16 back between the two gears 2 15, as the electric push rod 2 pulls the bottom end of the telescopic airbag 3 together with the rack 10 to move downward for a distance, the gear 2 15 at the right end of the meshing transmission is engaged. While the nozzle 8 is reset, the gear 2 15 at the right end will also transmit the gear 2 15 at the left end through the connecting gear 16, thereby causing the trigger wheel 28 connected to the left end gear 2 15 to rotate a certain angle, so that the protrusion of the trigger wheel 28 abuts against the right side of the slide plate 27, and force is applied to it along the curve, so that the slide plate 27 moves to the left and compresses the spring. The displaced slide plate 27 will abut the abutting protrusion of the limit shaft 25 through the abutting protrusion, so that the limit shaft 25 slides on the outer wall of the spline shaft 26 and compresses the spring, so that the locking gasket of the limit shaft 25 is separated from the locking gasket on the rotating shaft 24 connected to the half gear 20, thereby releasing the lock and allowing the half gear 20 to rotate.

[0029] Please see attached Figure 8 The rear side of the valve ball 12 penetrates the outer wall of the valve body 11 and is fixedly connected to the gear 13. The right side of the frame 9 is fixedly connected to the rack 2 14. When the rack 2 14 is meshed with the gear 13, the frame 9 will switch the flow direction of the reversing valve. Specifically, during the displacement of the frame 9, the gear 13 connected to the valve ball 12 will rotate by meshing with the rack 2 14 connected thereto, thereby turning the opening of the valve ball 12, thereby changing the direction of the subsequently guided air flow, and guiding the air to pressurize the interior of the nozzle 8 when spraying the cleaning liquid. After spraying, the output port is switched to reduce the impact of negative pressure.

[0030] Please see attached Figure 4 The left side of the bottom end of the telescopic airbag 3 is fixedly connected with a rack 10, and the rack 10 is meshed and connected with the left end rotating wheel 5; Specifically, during the pushing process of the electric push rod 1, the bottom end of the telescopic airbag 3 will also drive the rack 10 to mesh, and the rack 10 meshes and transmits the gear 2 15 on the right end to rotate, so that the rotating wheel 5 connected to the gear 2 15 on the right end drives the nozzle 8 connected through the telescopic rod 6 and the curved rod 7 to rotate, thereby changing the spraying position of the nozzle 8 to cover a larger spraying area.

[0031] Please see attached Fig.14 The right end of the nozzle 8 is supported by the internal protrusion of the frame 9, so that when the frame 9 is lifted and displaced, the nozzle 8 is lifted together.

[0032] Please see attached Figure 2 , Attachment Figure 3 and attached Fig.13 The liquid storage box 31 is located at the top left end of the interior of the door shell 1. The position of the liquid storage box 31 is higher than the position height of the frame 9. The liquid inlet of the liquid storage box 31 passes through the outer wall of the door shell 1, and a rubber plug is provided at the opening of the liquid inlet. By opening the rubber plug, cleaning liquid can be added to the interior of the liquid storage box 31. Through the height difference and the principle of the communicating vessel, the cleaning liquid is transported to the nozzle 8 along the hose through pressure.

[0033] Please see attached Figure 5 The baffle 30 is located on the top side of the frame 9 and is rotatably connected to the outer side of the outer wall of the door shell 1 through a torsion spring. When the frame 9 is lifted, force will be applied to its bottom side to rotate and open it for cleaning.
