[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-3 The utility model provides a car hatch sealing assembly, including a door frame 1, a sealing structure 2, a cleaning structure 3 and a fixing assembly 4. The sealing structure 2 is arranged on the outer side of the end of the door frame 1, the cleaning structure 3 is arranged inside the sealing structure 2, and the fixing assembly 4 is arranged between the sealing structure 2 and the door frame 1.

[0024] The sealing structure 2 consists of a sealing strip body 201, a first lip 203, a second lip 204, a sealing bubble tube 205, a third lip 206, and a fourth lip 208. A first sealing groove 202 is defined on the left side of the sealing strip body 201, with the first lip 203 positioned on one side of the first sealing groove 202. The second lip 204 is positioned at the end of the first sealing groove 202, the sealing bubble tube 205 is positioned on the outside of the sealing strip body 201 away from the door frame 1, and the third lip 206 is positioned at the end of the sealing strip body 201.

[0025] The cleaning structure 3 consists of an internal cavity 301, a filling material 302, a gas flow channel 303, a gas collecting cavity 304 and an air jet port 305. The internal cavity 301 is provided inside the sealing bubble tube 205, and the internal cavity 301 is filled with the filling material 302. The gas flow channel 303 is opened inside the sealing strip body 201, and the gas collecting cavity 304 is opened inside the second lip edge 204.

[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that a second sealing groove 207 is defined between the third lip 206 and the sealing strip body 201 , and the second sealing groove 207 is used for clamping the inner decorative panel of the vehicle door.

[0027] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the fourth lip 208 is provided on the other side of the first sealing groove 202;

[0028] The larger end of the fourth lip 208 means that its contact area with the door frame 1 is also increased. The larger contact area provides a stronger sealing force, thereby more effectively preventing external dust, moisture, or other contaminants from entering the interior of the first sealing groove 202. It also better adapts to gaps of varying sizes or tolerances. This adaptability makes the sealing structure more flexible for door frames of varying thicknesses.

[0029] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the material of the filling material 302 is set to polystyrene foam material;

[0030] Polystyrene foam material has a closed-cell structure, low water absorption, excellent water resistance, low density, and is relatively light in weight. It has good gas and water barrier properties. It is not only highly elastic, but can also release or absorb gas when squeezed.

[0031] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that both ends of the gas flow channel 303 are connected to the internal cavity 301 and the gas collecting cavity 304 respectively, and the gas injection port 305 is opened between the gas collecting cavity 304 and the outer wall of the second lip 204 .

[0032] According to the above working process, it can be known that: through the provided cleaning structure 3, when the vehicle door is closed, the sealing bubble tube 205 is squeezed, so that the internal cavity 301 and the filling material 302 inside are contracted, and the internal gas flows into the gas flow channel 303 and the gas collecting cavity 304, and is finally discharged through the jet port 305, blowing the air flow to the area between the second lip 204 and the door frame 1, thereby blowing away dust and impurities, improving the cleanliness of the connection position, and ensuring the overall beauty of the vehicle.

[0033] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the fixing assembly 4 consists of a fixing plate 401, a threaded rod 402, a turntable 403, a connecting plate 404 and a suction cup 405. The fixing plate 401 is fixedly connected to the inside of the first sealing groove 202, the threaded rod 402 is threadedly connected to the inside of the fixing plate 401, and the threaded rod 402 is threadedly connected to the sealing strip body 201, and the turntable 403 is fixedly connected to one end of the threaded rod 402.

[0034] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the connecting plate 404 is rotatably connected to the other end of the threaded rod 402 , and the suction cup 405 is fixedly connected to the side of the connecting plate 404 away from the threaded rod 402 .

[0035] This solution has the following working process: when in use, the first sealing groove 202 is inserted into the outer side of the end of the door frame 1, and the door frame 1 is fixed by the first lip 203 and the fourth lip 208 on both sides to initially ensure that the sealing strip body 201 is installed on the outside of the door frame 1, and then the turntable 403 is rotated to drive the threaded rod 402 to move, and the suction cup 405 is driven to move closer to the door frame 1 through the connecting plate 404 until the suction cup 405 is completely sucked tightly with the door frame 1, and the sealing strip body 201 is installed on the outside of the door frame 1 again to improve the installation stability of the sealing structure 2 and avoid the sealing structure 2 from falling off after long-term use; When the door is closed, the sealing bubble tube 205 is squeezed, causing the internal cavity 301 and the filling material 302 to shrink, so that the internal gas flows into the gas flow channel 303 and the gas collecting cavity 304, and is finally discharged through the air jet 305, blowing the air flow to the area between the second lip 204 and the door frame 1, thereby blowing away dust and impurities, avoiding the accumulation of dust and debris between the second lip 204 and the door frame 1 during long-term use, and improving the practicality of the structure; at the moment the car door is opened, the filling material 302 absorbs the outside air through the air jet 305, and at the same time, through its own elasticity, it returns to its original state, which is convenient for continued squeezing next time.

[0036] In summary: through the provided cleaning structure 3, when the vehicle door is closed, the sealing bubble tube 205 is squeezed, so that the internal cavity 301 and the filling material 302 inside are contracted, and the internal gas flows into the gas flow channel 303 and the gas collecting cavity 304, and is finally discharged through the jet port 305, blowing the air flow to the area between the second lip 204 and the door frame 1, thereby blowing away dust and impurities, improving the cleanliness of the connection position, and ensuring the overall beauty of the vehicle; through the provided fixing component 4, the sealing strip body 201 can be installed and fixed on the outside of the door frame 1 again, thereby improving the installation stability of the sealing structure 2 and avoiding the sealing structure 2 from falling off after long-term use.
