[0042] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0043] The vehicle provided in the embodiment of the present application includes a vehicle body and a vehicle door, wherein the vehicle body has a driving space and an entrance connected to the driving space, and the vehicle door is arranged at the entrance and can be opened and closed relative to the entrance, that is, to open the entrance or close the entrance.

[0047] Furthermore, the water cut structure also includes an inner door water cut (not shown in the figure), which is arranged opposite to the outer door water cut 100, installed on the inner door panel, and located on the other side of the door glass 300, that is, the inner door water cut and the outer door water cut 100 are respectively arranged on both sides of the door glass 300, and the upper part of the inner door water cut and the upper part of the outer door water cut 100 clamp the door glass 300 from the inside and the outside, respectively, and contact with the two side surfaces of the door glass 300, so as to jointly support and seal the glass.

[0048] The vehicle door outer water cut 100 provided in the embodiment of the present application includes a water cut body 10 and a sealing body 20, wherein the water cut body 10 is arranged on the vehicle door outer panel 200, and along the first preset direction (the front and rear directions of the vehicle), the front and rear ends of the water cut body 10 have notches. When the water cut body 10 is installed on the vehicle door outer panel 200, the water cut body 10 and the two ends of the vehicle door outer panel 200 have gaps respectively.

[0049] Further, the sealing body 20 is arranged on the water-cut body 10, and the sealing body 20 and the water-cut body 10 are an integral structure. At least the sealing body 20 can be embedded in the gap between the water-cut body 10 and the door outer panel 200, and seal the gap. In other words, part of the sealing body 20 is arranged near the notch of the water-cut body 10, and when the water-cut body 10 is installed on the door outer panel 200, the sealing body 20 can seal the gap between the door outer panel 200 and the water-cut body 10.

[0050] In the related art, when the outer water cut of a vehicle door is installed on the outer panel of the vehicle door, there is a gap between the outer water cut of the vehicle door and the front and rear ends of the vehicle door outer panel. Foam is usually filled in the gap. The foam is generally bonded to the gap by tape or glue, which is easy to fall off, resulting in poor sealing between the outer water cut of the vehicle door and the outer panel of the vehicle door.

[0051] However, the door outer water cut provided by the embodiment of the present application includes a water cut body and a sealing body of an integrated structure, which can prevent the sealing body from falling off the water cut body. This can improve the sealing performance between the door and the door outer water cut, thereby reducing the noise generated by the vibration of the vehicle body and the phenomenon of external noise being transmitted into the vehicle, thereby improving the user experience.

[0052] like Figure 4 As shown, the outer water cut of the vehicle door 100 provided in the embodiment of the present application has an axial cross-section of the water cut body 10 that is an inverted U-shape, and includes a first sealing edge 11 and a second sealing edge 12.

Correspondingly, the sealing body 20 is provided with a first sealing groove matched with the first sealing lip 111, and the first sealing groove is located on the side of the sealing body 20 facing the first sealing edge 11.

[0055] When the door outer water cut 100 is installed on the door outer panel 200, the first sealing lip 111 is embedded in the first sealing groove, and the first sealing lip 111 is sealed and connected to the first sealing groove. Such an arrangement can improve the sealing performance between the door outer water cut 100 and the door outer panel 200.

[0056] In order to improve the structural strength of the outer water cut 100 of the vehicle door and prevent the outer water cut 100 of the vehicle door from deforming and affecting the sealing performance, the outer water cut 100 of the vehicle door in the embodiment of the present application also includes a water cut inner skeleton 30. The axial cross-section of the water cut inner skeleton 30 is an inverted U-shape. The water cut inner skeleton 30 includes a first supporting edge 31 and a second supporting edge 32 connected to each other, wherein at least a portion of the first supporting edge 31 is arranged in the first sealing edge 11 to improve the structural strength of the first sealing edge 11; at least a portion of the second supporting edge 32 is arranged in the second sealing edge 12 to improve the structural strength of the second sealing edge 12.

[0057] In one embodiment, the first supporting edge 31 is exposed to the bottom end surface of the first sealing edge 11, and the partial sealing body 20 seals the bottom end surface of the first sealing edge 11. For example, one end of the first supporting edge 31 is connected to the second supporting edge 32, and one end of the first supporting edge 31 away from the second supporting edge 32 extends to the bottom end surface of the first sealing edge 11 and is exposed. The partial sealing body 20 covers the bottom end surface of the first sealing edge 11, and the partial sealing body 20 is embedded in the gap between the first sealing edge 11 and the door outer panel 200.

[0058] In this way, the water-cut inner frame 30 is configured as a metal structure, and the end surface of the first supporting edge 31 exposed to the environment is sealed by the sealing body 20, which can prevent water vapor from corroding the first supporting edge 31 and improve the service life and reliability of the first supporting edge 31.

[0059] Based on the above embodiments, the cross-section of the sealing body 20 provided in the embodiment of the present application is L-shaped, and the sealing body 20 includes a first sealing portion 21 and a second sealing portion 22, wherein the first sealing portion 21 is in contact with the bottom end surface of the first sealing edge 11, that is, the first sealing portion 21 covers the bottom end surface of the first sealing edge 11.

[0060] The second sealing portion 22 is arranged in the gap between the inner side surface of the first sealing edge 11 and the vehicle door outer panel 200, and the above-mentioned first sealing groove is located on the side of the second sealing portion 22 facing the first sealing edge 11, and the side of the second sealing portion 22 away from the first sealing edge 11 is in contact with the vehicle door outer panel 200, that is, one side of the second sealing portion 22 is sealed and connected to the first sealing edge 11, and the other side of the second sealing portion 22 is sealed and connected to the vehicle door outer panel 200.

[0061] In the embodiment of the present application, at least one second sealing lip 121 is provided on the inner side of the second sealing edge 12 facing the vehicle door outer panel 200. For example, the second sealing edge 12 is provided with two second sealing lips 121, and along the extension direction of the second sealing edge 12, the two second sealing lips 121 are arranged at intervals up and down; one end of the second sealing lip 121 is connected to the second sealing edge 12, and one end of the second sealing lip 121 away from the second sealing edge 12 extends obliquely upward and is sealed and connected to the vehicle door outer panel 200. Such an arrangement can improve the sealing performance between the second sealing edge 12 and the vehicle door outer panel 200.

[0062] On the basis of the above-mentioned embodiment, the door outer water cut 100 provided in the embodiment of the present application further includes a water cut outer frame 40, which is detachably mounted on the water cut body 10. Exemplarily, the outer side of the water cut body 10 away from the door glass 300 is respectively provided with a first mounting lip 122 and a second mounting lip 123, the first mounting lip 122 is located at the top of the water cut body 10 and extends obliquely upward, the first mounting lip 122 extends toward the inside, and forms a first card slot with the water cut body 10. The second mounting lip 123 is located at the bottom of the water cut body 10 and extends obliquely downward; and the second mounting lip 123 extends toward the outside, and forms a second card slot with the water cut body 10.

[0063] Furthermore, the top of the water-cut exoskeleton 40 is provided with a first clamping part that matches the first clamping slot, and the bottom of the water-cut exoskeleton 40 is provided with a second clamping part that matches the second clamping slot. The water-cut exoskeleton 40 is clamped to the first clamping slot through the first clamping part, and is clamped to the second clamping slot through the second clamping part. In this way, the water-cut exoskeleton 40 and the water-cut body 10 can be detachably installed, and the installation is convenient and the structure is simple.

[0064] Preferably, a support lip 124 is provided on the side of the water-cut body 10 facing the water-cut exoskeleton 40, the support lip 124 is located on the second sealing edge 12, one end of the support lip 124 is connected to the second sealing edge 12, and the other end of the support lip 124 abuts against the inner side surface of the water-cut exoskeleton 40. In this way, the support lip 124 supports the water-cut exoskeleton 40 outward to prevent the water-cut exoskeleton 40 from being deformed after being squeezed, thereby ensuring the beautiful appearance of the water-cut exoskeleton 40.

[0065] Furthermore, the water-cut body 10 is also provided with a press lip 125, which is located below the second clamping portion. The press lip 125 extends obliquely downward and extends to the bottom of the water-cut outer frame 40. In this way, the upper surface of the press lip 125 can contact the lower end of the water-cut outer frame 40, and the lower surface of the press lip 125 abuts against the door outer panel 200, that is, the press lip 125 is located between the door outer panel 200 and the water-cut outer frame 40, so as to prevent the water-cut outer frame 40 from scratching the surface of the door outer panel 200.

[0066] Continue reading Figure 4 The vehicle door outer water cut 100 provided in the embodiment of the present application also includes a third sealing lip 112 and a fourth sealing lip 113, wherein the third sealing lip 112 is located on the side of the first sealing edge 11 facing the vehicle door glass 300, and one end of the third sealing lip 112 is connected to the middle part of the first sealing edge 11, and the other end of the third sealing lip 112 extends obliquely upward toward one side of the vehicle door glass 300 and abuts against the vehicle door glass 300.

[0067] The fourth sealing lip 113 is arranged at the top of the water-cut body 10 and is located on the side of the water-cut body 10 facing the door glass 300. The fourth sealing lip 113 is located above the third sealing lip 112, and a certain distance is maintained between the two. The third sealing lip 112 is provided with a secondary sealing lip 114 at one end away from the first sealing edge 11, and the secondary sealing lip 114 extends in the direction where the fourth sealing lip 113 is located and is arranged close to the fourth sealing lip 113.

[0068] With such arrangement, when the third sealing lip 112 is deformed, the secondary sealing lip 114 provides further elastic support to the third sealing lip 112, ensuring the fit between the third sealing lip 112 and the door glass 300, thereby ensuring the sealing effect between the door outer water cut 100 and the door glass 300. Also, when the door glass 300 shakes, the fourth sealing lip 113 can play a certain supporting role on the door glass 300, preventing the door glass 300 from moving outward, reducing the abnormal sound generated by the collision between the door glass 300 and the door outer water cut 100, and further reducing vibration noise.
