[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figure 1-5 As shown, a rear tank cleaning device of an automobile according to an embodiment of the present invention comprises a cleaning assembly 2, which is arranged on a vehicle body 1, on which a rear door 3 is movably mounted, a trunk 4 is fixedly opened inside the vehicle body 1, two connecting brackets 31 are mounted on one side of the rear door 3, and the rear door 3 is connected to the inside of the trunk 4 through the two connecting brackets 31, and the cleaning assembly 2 comprises a fixed L-shaped frame 21 mounted at the rear window position of the vehicle body 1 and a sliding L-shaped frame 22 movably mounted inside the fixed L-shaped frame 21;

[0035] A sliding column 215 is movably installed inside the fixed L-shaped frame 21 , and the sliding column 215 is fixedly installed on the outside of the sliding L-shaped frame 22 . A telescopic member 214 is installed between the sliding L-shaped frame 22 and the fixed L-shaped frame 21 , and one end of the telescopic member 214 is connected to the sliding column 215 .

[0036] Specifically, after the vehicle has been stationary for a period of time, there will be some debris such as dust and fallen leaves on the vehicle. When the tailgate 3 needs to be opened, the tailgate 3 will rotate. At this time, the debris on the tailgate 3 will gradually fall onto the rear window of the vehicle body 1 as the tailgate 3 rotates. Because the cleaning assembly 2 is fixed to the lowermost position of the rear window by structural adhesive, the initially dumped debris can fall into the sliding L-shaped frame 22 in the fixed L-shaped frame 21. As the tailgate 3 continues to rotate, the gap between the tailgate 3 and the rear window will become larger and larger. The telescopic member 214 electrically connected to the vehicle will extend, and infrared sensing can also be used to allow the tailgate 3 to rotate to a certain angle, and then the telescopic member 214 will extend. After the telescopic member 214 is extended, it drives the sliding column 215 and the sliding L-shaped frame 22 to move toward the trunk 4 until they pass through the gap between the rear window and the tailgate 3 and enter the trunk 4. At this time, the debris that is dumped due to the continued rotation of the tailgate 3 will enter the fixed L-shaped frame 21 and the sliding L-shaped frame 22, and will not enter the trunk 4. The debris is collected for subsequent cleaning.

[0037] like Figure 4-5 As shown, an arc groove 211 is provided inside the fixed L-shaped frame 21 on one side facing the tailgate 3, first through grooves 212 are provided inside both sides of the fixed L-shaped frame 21, sliding grooves 213 are provided inside both sides of the fixed L-shaped frame 21, sliding columns 215 are slidably installed inside the sliding grooves 213, and telescopic members 214 are fixedly installed inside the fixed L-shaped frame 21.

[0038] Specifically, the initial position of the sliding column 215 is inside the sliding groove 213, and as the telescopic member 214 extends, the sliding column 215 will move inside the sliding groove 213. At this time, the sliding column 215 and the sliding L-shaped frame 22 will move simultaneously until the sliding column 215 moves to the limit position inside the sliding groove 213, and the sliding L-shaped frame 22 stops moving. The movement of the sliding L-shaped frame 22 increases the debris collection area of ​​the cleaning component 2, and the sliding L-shaped frame 22 enters the trunk 4 for collection, so as to prevent the debris from being dumped and entering the trunk 4 along the gap between the rear window and the tailgate 3.

[0039] like Figure 5-6As shown, a rack 2131 is fixedly installed on the upper inner wall of the sliding groove 213, and the thickness of the rack 2131 is smaller than the width of the sliding groove 213. A first annular groove 2151 and a second annular groove 2152 are fixedly opened inside the sliding column 215, and a plurality of toothed rings 2153 are fixedly installed inside the second annular groove 2152, and the toothed rings 2153 are meshed with the rack 2131. The telescopic member 214 includes an electrically driven telescopic rod 2141, and one end of the electrically driven telescopic rod 2141 is located inside the sliding groove 213, and a fixing ring 2142 is fixedly installed on one end of the electrically driven telescopic rod 2141, and the fixing ring 2142 is movably mounted inside the first annular groove 2151.

[0040] Specifically, the extension of the electrically driven telescopic rod 2141 drives the sliding column 215 to move toward the rack 2131. At this time, the sliding L-shaped frame 22 slides inside the fixed L-shaped frame 21. When the sliding column 215 moves to one side of the rack 2131 and is about to pass through the rack 2131, the gear ring 2153 will mesh with the rack 2131, and the sliding column 215 continues to move toward the position of the rack 2131, which will cause the sliding column 215 to rotate clockwise as a whole, thereby driving the sliding L-shaped frame 22 to rotate clockwise, that is, after the sliding L-shaped frame 22 moves to a certain distance inside the fixed L-shaped frame 21, it rotates clockwise. At this time, the lower side of the sliding L-shaped frame 22 is against the inside of the arc groove 211, ensuring that there is no gap between the fixed L-shaped frame 21 and the sliding L-shaped frame 22, and debris will fall The interior of the fixed L-shaped frame 21 and the sliding L-shaped frame 22, and at this time the sliding L-shaped frame 22 is no longer in a tilted state, but in a relatively horizontal state, thereby increasing the debris collection area of ​​the sliding L-shaped frame 22. When the lower side of the sliding L-shaped frame 22 is abutted, the gear ring 2153 and the rack 2131 are also in abutted state. When the tailgate 3 is closed, the electrically driven telescopic rod 2141 contracts and drives the sliding L-shaped frame 22 to complete a process of first rotating counterclockwise and then sliding toward the interior of the fixed L-shaped frame 21. At this time, the fixed L-shaped frame 21 and the sliding L-shaped frame 22 form a collection area, and the debris originally collected by the fixed L-shaped frame 21 will be in the sliding L-shaped frame 22. When the fixed L-shaped frame 21 and the sliding L-shaped frame 22 are collecting debris, the normal activation of the tailgate 3 will not be affected.

[0041] like Figure 7 As shown, the sliding L-shaped frame 22 has two fixing grooves 221 on one side facing the tailgate 3 , rubber sheets 222 are fixedly installed inside the two fixing grooves 221 , and second through grooves 223 are formed inside the two sides of the fixing grooves 221 .

[0042] Specifically, when the sliding L-shaped frame 22 moves toward the position of the tailgate 3, the fixing groove 221 corresponds to the position of the connecting bracket 31. In some models of vehicles, the connecting bracket 31 is located closer to the rear window. During the sliding of the sliding L-shaped frame 22, the rubber sheet 222 will contact the connecting bracket 31. At this time, the rubber sheet 222 will be deformed to form a U-shaped state, which is adaptable to different models of vehicles and does not affect the debris collection function of the sliding L-shaped frame 22.

[0043] Embodiment 2: Figure 8 As shown, compared with Example 1, another embodiment of the present invention is: an impact assembly 24 is movably mounted on one side of the fixed L-shaped frame 21 through screws, a wiping component 23 is fixedly mounted on one side of the fixed L-shaped frame 21, the wiping component 23 includes a placement frame 231 and a brush 232 movably mounted inside the placement frame 231, and a U-shaped picking piece 233 is fixedly mounted on the upper side of the tail of the brush 232.

[0044] Specifically, in some public places, the debris on the vehicle cannot be swept to the ground. At this time, the tailgate 3 is opened, the sliding L-shaped frame 22 slides out from the fixed L-shaped frame 21, and the brush 232 is taken out by the U-shaped taking piece 233, and the brush 232 is separated from the placement frame 231. The brush 232 is used to sweep the debris on the tailgate 3 that cannot be moved due to tipping, and the debris is allowed to enter the fixed L-shaped frame 21 or the sliding L-shaped frame 22 for collection, thereby solving the problem of stubborn debris left on the tailgate 3.

[0045] like Fig. 9 As shown, the impact assembly 24 includes a fixed housing 241 connected to one side of the fixed L-shaped frame 21 by screws, an impact water gun 242 is fixedly installed inside the fixed housing 241, and a detachable water pipe 243 is movably installed on one side of the impact water gun 242.

[0046] Specifically, the detachable water pipe 243 can be detached. When driving normally, the detachable water pipe 243 is detached and placed inside the vehicle. The fixed L-shaped frame 21 and the sliding L-shaped frame 22 collect debris inside. When the sliding L-shaped frame 22 slides into the fixed L-shaped frame 21, the bottom of the sliding L-shaped frame 22 will scoop up the debris inside the fixed L-shaped frame 21, allowing the debris inside the fixed L-shaped frame 21 to enter the sliding L-shaped frame 22. That is, there are originally collected debris inside the sliding L-shaped frame 22 and the debris inside the fixed L-shaped frame 21. When the internal debris needs to be cleaned, one end of the detachable water pipe 243 is brought into contact with the water source, and the water flow is sprayed out through the impact water gun 242. At this time, the water flow will enter the fixed L-shaped frame 21 through a first through groove 212 and a second through groove 223, and the internal debris of the fixed L-shaped frame 21 will be washed away from the other first through groove 212 and the second through groove 223. The water flow impact structure is set up, which can easily dispose of the debris collected by the fixed L-shaped frame 21 and the sliding L-shaped frame 22.

[0047] Working principle: when the tailgate 3 is opened, the tailgate 3 will rotate. At this time, the debris on the tailgate 3 will gradually fall to the rear window position of the vehicle body 1 as the tailgate 3 rotates. Because the cleaning assembly 2 is fixed to the lowermost position of the rear window by structural adhesive, the initially dumped debris can fall into the sliding L-shaped frame 22 in the fixed L-shaped frame 21. As the tailgate 3 continues to rotate, the gap between the tailgate 3 and the rear window position will become larger and larger. At this time, the telescopic member 214 electrically connected to the vehicle will extend. It can also be extended by infrared sensing to allow the tailgate 3 to rotate a certain angle before the telescopic member 214 extends. After the telescopic member 214 extends, it drives the sliding column 215 and the sliding L-shaped frame 22 to move toward the trunk 4 position until they pass through the gap between the rear window and the tailgate 3 and enter the trunk 4. At this time, the debris dumped due to the continued rotation of the tailgate 3 will enter the fixed L-shaped frame 21 and the sliding L-shaped frame The fixed L-shaped frame 21 and the sliding L-shaped frame 22 collect the debris, and when the sliding L-shaped frame 22 slides toward the fixed L-shaped frame 21, the bottom of the sliding L-shaped frame 22 scoops up the debris in the fixed L-shaped frame 21, allowing the debris in the fixed L-shaped frame 21 to enter the sliding L-shaped frame 22. That is, the sliding L-shaped frame 22 contains the previously collected debris and the debris in the fixed L-shaped frame 21. When it is necessary to clean up these debris, let one end of the detachable water pipe 243 contact the water source, and spray water through the impact water gun 242. At this time, the water will enter the fixed L-shaped frame 21 through the first through groove 212 and the second through groove 223, and wash away the debris inside the fixed L-shaped frame 21 from the other first through groove 212 and the second through groove 223. The water flow impact structure is set up, which can easily dispose of the debris collected by the fixed L-shaped frame 21 and the sliding L-shaped frame 22.
