In the embodiment, the outer water cutting body 302 is fixed without using external connecting components, and no hole needs to be punched on the outer water cutting body 302, thereby improving the sealing performance.
[0054] Optionally, the fixed lip 3023 is arranged to be inclined in the up-down direction, thereby increasing the contact area with the side wall outer plate, improving the friction resistance between the fixed lip 3023 and the side wall outer plate, and increasing the connection reliability.
[0055] In some embodiments, referring to Figure 3 The outer water cutting body 302 is provided with a deformation channel 3024 along the extension path of the outer water cutting body 302, and the deformation channel 3024 is arranged on the outer periphery of the fixed groove 3022.
[0056] The side wall outer plate is in interference fit with the fixed groove 3022, thereby ensuring the firmness of the connection. Since the outer water cutting body 302 is provided with the deformation channel 3024, after the side wall outer plate is inserted into the fixed groove 3022, the outer water cutting body 302 deforms into the deformation channel 3024, and then can only wrap on the side wall outer plate. The embodiment improves the deformation capability of the outer water cutting body 302, so that the outer water cutting body 302 is in close contact with the side wall outer plate, and the friction resistance and the connection stability between the outer water cutting body 302 and the side wall outer plate are increased.
[0057] Based on the same inventive concept, the utility model also provides a vehicle. The vehicle comprises the vehicle window sealing and noise reduction structure.
[0058] The vehicle provided by the utility model adopts the vehicle window sealing and noise reduction structure, and the limiting piece 101 is arranged at the bottom end of the side wall decorative strip 1. Since the groove joint corner 202 abuts against the limiting piece 101 in the up-down direction, the gap formed by the side wall decorative strip 1 and the groove joint corner 202 in the up-down direction is closed, the sealing performance is improved, and the wind noise caused by the air flow entering the gap during the driving of the vehicle is avoided. The interference part 3021 of the outer water cutting decorative piece 3 interferes with the groove body 201 in the up-down direction, thereby sealing the gap between the outer water cutting decorative piece 3 and the groove body 201. On the one hand, the problem that the water flow enters the vehicle through the gap and causes the sealing performance of the vehicle to decrease is avoided, and on the other hand, the situation that the air flow enters and exits the gap and causes wind noise is avoided. The utility model adopts the mode that the groove joint corner 202 abuts against the limiting piece 101 and the groove body 201 abuts against the outer water cutting decorative piece 3 to close the gap above the outer water cutting decorative piece 3, reduces the wind noise during the driving of the vehicle, improves the NVH performance of the vehicle, and improves the sealing performance of the vehicle window area.
