DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] Embodiment 1

[0038] refer to Figures 1 to 4 As shown, this embodiment provides a vehicle door outer water cut (hereinafter referred to as outer water cut), including an outer water cut body 10.

[0039] Specifically, refer to Figures 1 to 3 As shown, the outer water-cut body 10 has a clamping groove 3 for clamping the outer sheet metal 6 of the vehicle door, and a limiting member 4 is arranged in the clamping groove 3. At least part of the limiting member 4 is arranged on the groove wall of the clamping groove 3 away from the vehicle door glass 8, and the limiting member 4 is arranged close to the groove bottom of the clamping groove 3. The limiting member 4 is in contact with the outer sheet metal 6 of the vehicle door, so that the outer sheet metal 6 of the vehicle door provides a relatively large friction force for the outer water-cut body 10, thereby preventing the outer water-cut body 10 from flipping relative to the outer sheet metal 6 of the vehicle door.

[0040] By arranging a limit member 4 on the groove wall of the clamping groove 3 away from the door glass 8, the limit member 4 is arranged close to the groove bottom of the clamping groove 3, and the side of the limit member 4 facing the door outer sheet metal 6 is used to abut against the door outer sheet metal 6, so that during the assembly process, the limit member 4 can abut against the door outer sheet metal 6, and the limit member 4 cooperates with the door outer sheet metal 6 to generate a relatively large friction force between the outer water cut and the door outer sheet metal 6, thereby preventing the outer water cut from flipping around the door outer sheet metal 6 to a certain extent, making the gap between the outer water cut and the door outer panel more uniform, which helps to achieve a better and more beautiful appearance.

[0041] At the same time, the cooperation between the limiting member 4 and the outer door sheet metal 6 prevents the outer water-cut body 10 from rotating around the outer door sheet metal 6, that is, the outer water-cut body 10 will not flip over under the action of the limiting member 4 and the outer door sheet metal 6, thereby enhancing the assembly stability of the outer water-cut body 10 on the outer door sheet metal 6, thereby improving the structural stability of the outer water-cut body 10, and further avoiding the collapse, warping and other phenomena of the outer water-cut body 10 to a certain extent, helping to ensure the installation surface difference between the outer water-cut and the outer door panel, and improving the appearance quality.

[0042] In some implementations, reference Figures 1 to 3 As shown, the outer water cut body 10 includes an outer water cut body 1 and a decorative strip 2 . The decorative strip 2 is connected to a side of the outer water cut body 1 facing away from the door glass 8 . The clamping groove 3 is provided on the outer water cut body 1 .

[0043] The vehicle door outer water cut, vehicle door assembly and vehicle provided in this embodiment are provided with an outer water cut body 10, and the outer water cut body 10 has a clamping groove 3 for clamping the vehicle door outer sheet metal 6, and a limit member 4 is arranged in the clamping groove 3, at least part of the limit member 4 is arranged on the groove wall of the clamping groove 3 away from the vehicle door glass, and the limit member 4 is arranged near the groove bottom of the clamping groove 3, so that during the assembly process, once the outer water cut body 10 moves, the limit member 4 can be pressed against the vehicle door outer sheet metal 6, and the abutment and cooperation between the limit member 4 and the vehicle door outer sheet metal 6 can provide a relatively large friction force for the outer water cut body 10, thereby avoiding the phenomenon of the outer water cut body 10 flipping around the vehicle door outer sheet metal 6 during the assembly process to a certain extent, enhancing the installation stability between the outer water cut body 10 and the vehicle door outer sheet metal 6, and thereby making the gap between the vehicle door outer water cut and the vehicle door outer panel more uniform, which is helpful to achieve the appearance surface difference. At the same time, the abutment between the limiter 4 and the door outer sheet metal 6 also avoids the collapse, warping and other phenomena caused by the flipping of the outer water cut body 10 to a certain extent, improves the structural stability of the outer water cut body 10, and further ensures the appearance quality between the door outer water cut and the door outer panel.

[0044] Definition: The X direction (corresponding to the length of the vehicle) is defined as the longitudinal direction, the Y direction (corresponding to the width of the vehicle) as the transverse direction, and the Z direction (corresponding to the height of the vehicle) as the vertical direction. Directional words such as "front" and "rear" usually refer to the X direction, with the driver's position facing the front; "left" and "right" correspond to the Y direction, usually referring to the left and right defined when the driver is facing forward; "up" and "down" correspond to the Z direction.

[0045] To summarize, by arranging a limit member 4 on the groove wall of the clamping groove 3, the limit member 4 is located on the side of the clamping groove 3 facing the decorative strip 2 in the Y direction, and is arranged close to the top of the clamping groove 3 in the Z direction, and the limit member 4 cooperates with the outer door sheet metal 6 to limit the external water cut in the Y direction. That is to say, the external water cut will not flip over in the Y direction under the cooperation of the limit member 4 and the outer door sheet metal 6, that is, it has an anti-flip function, thereby improving the assembly stability and structural stability of the external water cut in the Y direction, and then ensuring the Y-direction surface difference of the external water cut on the outer door panel.

[0046] In some implementations, the clamping groove 3 has two opposite groove walls, and a first lip is respectively provided on the two opposite side walls of the clamping groove 3. When the outer sheet metal 6 of the vehicle door is connected to the clamping groove 3 of the external water-cut body 1, the first lip on the groove wall of the clamping groove 3 is respectively in sealing contact with the outer sheet metal 6 of the vehicle door to stably and firmly connect the outer sheet metal 6 of the vehicle door in the clamping groove 3.

[0047] In specific implementation, a second lip is provided on the side of the outer water cut body 1 away from the decorative strip 2, and the second lip is in sealing contact with the door glass 8. When the door glass 8 is raised or lowered, the second lip generates friction with the door glass 8, thereby realizing the water wiping and dust prevention functions of the outer water cut.

[0048] The vehicle door outer water cut, vehicle door assembly and vehicle provided in this embodiment are provided with an outer water cut body 1 and a decorative strip 2, wherein the decorative strip 2 is connected to one side of the outer water cut body 1, and the outer water cut body 1 has a clamping groove 3 for clamping the vehicle door outer sheet metal 6, and a limiting member 4 is provided on the groove wall of the clamping groove 3 facing the decorative strip 2, and the limiting member 4 is provided near the groove bottom of the clamping groove 3. In this way, during the assembly process, once the outer water cut body 1 is displaced, the limiting member 4 can be abutted against the vehicle door outer sheet metal 6, and the abutting cooperation between the limiting member 4 and the vehicle door outer sheet metal 6 can provide a relatively large friction force for the outer water cut body 1, thereby avoiding the phenomenon of the outer water cut flipping around the vehicle door outer sheet metal 6 during the assembly process to a certain extent, enhancing the installation stability between the outer water cut body 1 and the vehicle door outer sheet metal 6, and thereby making the gap between the outer water cut and the vehicle door outer panel more uniform, which is helpful to achieve the appearance surface difference. At the same time, the abutment between the limiter 4 and the door outer sheet metal 6 also avoids the collapse, warping and other phenomena of the decorative strip 2 caused by the flipping of the outer water cut body 1 to a certain extent, thereby improving the structural stability between the decorative strip 2 and the outer water cut body 1, that is, improving the overall structural stability of the outer water cut, thereby further ensuring the appearance quality between the outer water cut and the door outer panel.

[0049] In some embodiments, reference Figure 1 and Figure 3 As shown, the side of the limiting member 4 facing the door outer sheet metal 6 has a limiting inclined surface 41 , and the limiting inclined surface 41 abuts against the door outer sheet metal 6 .

[0050] By setting a limiting slope 41 on the side of the limiting member 4 facing the outer door sheet metal 6, the limiting slope 41 is made to abut against the outer door sheet metal 6. Under the condition of the same structure, the contact area between the limiting member 4 and the outer door sheet metal 6 is increased, that is, the abutting matching surface between the two is increased, so that the friction force applied by the outer door sheet metal 6 to the external water cut is greater, thereby playing a better anti-rollover limiting role on the external water cut at least in Y, further improving the assembly stability and structural stability of the external water cut in Y, and further ensuring the Y-direction surface difference of the external water cut on the outer door panel.

[0051] In some embodiments, continue to refer to Figure 1 and Figure 3 As shown, the vertical projection of the limiting slope 41 on the door outer sheet metal 6 is larger than the area of ​​the door outer sheet metal 6 combined with the limiting member 4 .

[0052] That is to say, the vertical projection of the limiting slope 41 on the door outer sheet metal 6 is relatively large, and the vertical projection of the limiting slope 41 on the door outer sheet metal 6 can cover the joint surface 61 of the door outer sheet metal 6 and the limiting component 4. In other words, the vertical projection of the joint surface 61 of the door outer sheet metal 6 on the limiting component 4 is located inside the limiting slope 41, thereby ensuring the effective abutment between the limiting slope 41 and the door outer sheet metal 6, thereby enhancing the anti-rollover limiting effect of the external water shear in the Y direction.

[0053] In some embodiments, reference Figure 1 and Figure 3 As shown, the limit member 4 is arranged at the junction of the bottom of the clamping groove 3 and the side wall of the clamping groove 3 away from the door glass 8, that is, the limit member 4 is arranged at the junction of the bottom of the clamping groove 3 and the side wall.

[0054] By setting the limit member 4 at the junction of the bottom and the side wall of the clamping groove 3, that is, a part of the limit member 4 extends along the Y direction of the clamping groove 3, and the other part of the limit member 4 extends along the Z direction of the clamping groove 3, the limit member 4 can limit the external water cut in the Y direction as well as in the Z direction. Therefore, the abutment cooperation between the limit member 4 and the outer door sheet metal 6 not only improves the assembly stability and structural stability of the external water cut in the Y direction, and makes the surface difference between it and the outer door panel in the Y direction better, but also makes the structural stability of the external water cut in the Z direction better, thereby ensuring that the surface difference of the external water cut on the outer door panel in the Z direction is better.

[0055] In some embodiments, reference Figure 1 and Figure 3As shown, the junction between the end of the door outer sheet metal 6 facing the bottom of the clamping groove 3 and the side wall of the door outer sheet metal 6 away from the door glass 8 has a joint surface 61. The side of the limiting member 4 facing the door outer sheet metal 6 has a limiting inclined surface 41, and the vertical projection of the limiting inclined surface 41 on the door outer sheet metal 6 is larger than the joint surface 61.

[0056] By setting the limiting member 4 at the junction of the bottom and the side wall of the clamping groove 3, and setting a limiting inclined surface 41 on the side of the limiting member 4 facing the outer door sheet metal 6, the limiting inclined surface 41 is matched with the outer door sheet metal 6. On the one hand, under the same structure, the contact area between the limiting member 4 and the outer door sheet metal 6 is increased, that is, the matching surface between the two is increased, so that the friction force applied by the outer door sheet metal 6 to the outer water cut is greater, thereby playing a better anti-flip limiting role on the outer water cut in Y, further improving the assembly stability and structural stability of the outer water cut in Y. On the other hand, it also plays a limiting role on the outer water cut in Z, which helps to ensure the surface difference between the outer water cut and the outer door panel in the Z direction, thereby further ensuring the appearance surface difference between the outer water cut and the outer door panel.

[0057] In a specific implementation, the above-mentioned joint surface 61 of the door outer sheet metal 6 is directly opposite to the limiting inclined surface 41 on the clamping groove 3, so that the two can abut and cooperate to limit the external water cut.

[0058] By arranging a limiting member 4 at the top of the clamping groove 3 for abutting against the outer door sheet metal 6, the upward distance between the top of the limiting groove and the outer door sheet metal 6 is reduced to a certain extent, thereby avoiding the phenomenon that the outer water-cut body 1 flips around the outer door sheet metal to the inside of the vehicle during the assembly process, thereby improving the structural stability.

[0059] In some embodiments, reference Figure 2 As shown, there is a preset gap L between the limiting slope 41 and the outer wall of the door outer sheet metal 6. The preset gap L is used to absorb assembly tolerance, and the preset gap is no greater than 0.3 mm.

[0060] By setting a preset gap between the limiting slope 41 and the outer wall of the door outer sheet metal 6, such as the above-mentioned joint surface 61, the preset gap is not greater than 0.3mm. On the one hand, the preset gap can absorb the assembly error between the outer water cut and the door outer sheet metal 6, and to a certain extent reduce the manufacturing accuracy of the outer water cut and the door outer sheet metal 6, which is convenient for the connection and assembly between the two. On the other hand, during the process of assembling the outer water cut on the door outer sheet metal 6, if the outer water cut shows signs of flipping, the limiting slope 41 can be relatively conveniently pressed against the door outer sheet metal 6, thereby providing a reliable limiting effect on the outer water cut in the Y direction, thereby preventing the outer water cut from flipping around the door outer sheet metal 6 in the Y direction toward the inside of the vehicle, and avoiding the appearance defects such as collapse and warping of the trim strip 2.

[0061] In some embodiments, the limiting member 4 is integrally formed with the outer water cut body 1 , has good integrity and high structural strength, and can provide a more stable limiting and anti-flipping effect for the outer water cut.

[0062] In other embodiments, the limiting member 4 can be connected to the groove wall of the clamping groove 3 by, for example, hot-melt connection, structural adhesive bonding, etc.

[0063] In some embodiments, reference Figures 1 to 3 As shown, the outer water cut body 10 includes an outer water cut body 1 and a decorative strip 2. The decorative strip 2 is connected to a side of the outer water cut body 1 that is away from the door glass 8, and a clamping groove 3 is provided on the outer water cut body 1.

[0064] The decorative strip 2 can be connected to the outer water-cut body 1 by, for example, snap-fitting.

[0065] In a specific implementation, the limiting member 4 is arranged on the groove wall of the clamping groove 3 on the side facing the decorative strip 2 .

[0066] A first limiting portion 11 is provided in the middle of the side of the outer water-cut main body 1 facing the decorative strip 2, and a second limiting portion 21 matching the first limiting portion 11 is provided on the side of the decorative strip 2 facing the outer water-cut main body 1, and the first limiting portion 11 is located in the middle of the height direction of the outer water-cut. When the outer water-cut main body 1 is connected to the decorative strip 2, the first limiting portion 11 and the second limiting portion 21 cooperate to limit the decorative strip 2.

[0067] It should be noted that the middle part of the outer water cut in the height direction can be specifically understood as the middle part of the outer water cut in the Z direction.

[0068] In specific implementation, the first limiting portion 11 is extended at least along the Y direction on the outer water cut body 1, and correspondingly, the second limiting portion 21 is extended at least along the Y direction on the decorative strip 2. When the first limiting portion 11 and the second limiting portion 21 are connected in cooperation, they can at least limit the decorative strip 2 in the Y direction, that is, the cooperation of the first limiting portion 11 and the second limiting portion 21 can support the decorative strip 2 in the Y direction of the outer water cut body 1, further avoiding the collapse and warping of the decorative strip 2, thereby improving the structural stability of the outer water cut in the Y direction. At the same time, it can also limit the decorative strip 2 in the Z direction, and the decorative strip 2 will not fall off, which helps to ensure the appearance difference.

[0069] By setting a first limiting portion 11 in the middle part of the outer water-cut main body 1 along the Z direction, and setting a second limiting portion 21 at a position corresponding to the first limiting portion 11 on the decorative strip 2, when the outer water-cut main body 1 and the decorative strip 2 are assembled in place, such as when they are buckled into place, the first limiting portion 11 and the second limiting portion 21 are matched and connected, so as to support and limit the decorative strip 2 in the Y direction and the Z direction, thereby improving the structural stability of the outer water-cut and further ensuring the appearance difference.

[0070] In specific implementation, the first limiting portion 11 is also extended along the X direction on the outer water-cut main body 1, and correspondingly, the second limiting portion 21 is also extended along the X direction on the decorative strip 2. That is to say, a long strip-shaped first limiting portion 11 is provided along the X direction on the outer water-cut main body 1, and a long strip-shaped second limiting portion 21 is provided along the X direction on the decorative strip 2. The matching connection area between the first limiting portion 11 and the second limiting portion 21 is large, thereby increasing the contact area between the outer water-cut main body 1 and the decorative strip 2, further improving the supporting and limiting effect on the decorative strip 2 in the Y direction and the Z direction, thereby further improving the structural stability between the outer water-cut main body 1 and the decorative strip 2.

[0071] In some embodiments, reference Figures 1 to 3 As shown, the first limiting portion 11 includes a limiting groove arranged in the middle of the outer water-cut body 1, and the second limiting portion 21 includes a limiting hook arranged on the decorative strip 2. The limiting hook can be extended into the limiting groove and clamped with the limiting groove. The structure is simple, easy to manufacture, and the connection is convenient and stable.

[0072] In some other implementations, the first limiting portion 11 may be, for example, a limiting hook disposed in the middle of the outer water-cut body 1 , and the second limiting portion 21 may be a limiting groove disposed on the decorative strip 2 .

[0073] In some embodiments, reference Figure 2 As shown, the limit hook includes a connecting portion 211 and a hook portion 212. One end of the connecting portion 211 is fixed to the decorative strip 2, and the hook portion 212 is fixed to the other end of the connecting portion 211, and the center line of the connecting portion 211 intersects the center line of the hook portion 212.

[0074] That is to say, a hook portion 212 is provided at the other end of the limit hook, i.e., the end of the limit hook facing the limit slot, and one end of the hook portion 212 is fixed on the connecting portion 211, and the other end of the hook portion 212 extends obliquely in a direction away from the connecting portion 211 and close to the limit slot, thereby forming a bent hook portion 212 at the other end of the limit hook, further improving the matching connection strength between the limit hook and the limit slot, thereby further improving the supporting and limiting effect on the decorative strip 2 in the Y and Z directions.

[0075] In some embodiments, reference Figures 1 to 3 As shown, the hook portion 212 extends from the other end of the connecting portion 211 toward the bottom of the clamping groove 3 .

[0076] That is to say, the hook portion 212 extends upward along the Z direction from the other end of the connecting portion 211, and the limiting hook is formed as a limiting barb bent upward by the hook portion 212, which is convenient for connection and has a better supporting and limiting effect after matching with the limiting groove.

[0077] In some embodiments, the limiting hook is integrally formed with the decorative strip 2 , has good integrity and high structural strength, and cooperates with the limiting groove to provide a more stable supporting and limiting effect for the decorative strip 2 .

[0078] Embodiment 2

[0079] refer to Figures 1 to 5 As shown, this embodiment further provides a vehicle door assembly, which includes a vehicle door outer sheet metal 6 and a vehicle door outer water cut, and the vehicle door outer water cut is installed on the vehicle door outer sheet metal 6.

[0080] In some embodiments, reference Figure 3 and Figure 5 As shown, the side of the door outer sheet metal 6 facing the clamping groove 3 has a edging 62, the clamping groove 3 is at least mounted on the edging 62, and the edging 62 is provided with a limiting protrusion 63 at the position where the rearview mirror 7 cooperates with the outer water cut, that is, the edging 62 located below the rearview mirror 7 extends the limiting protrusion 63 upward in the direction close to the outer water cut, and the limiting protrusion 63 extends vertically from the edging 62 toward the direction close to the bottom of the clamping groove 3, and abuts against the bottom of the clamping groove 3.

[0081] By setting a limiting protrusion 63 at a position below the rearview mirror 7 on the outer sheet metal 6 of the vehicle door, the limiting protrusion 63 extends upward along the Z direction toward the bottom of the groove close to the clamping groove 3, and the limiting protrusion 63 abuts against the bottom of the groove of the clamping groove 3, thereby providing support for the external water cut in the Z direction and playing a limiting role, thereby ensuring that the rearview mirror 7 and the external water cut are connected and matched, such as after crimping, the gap between the two is relatively uniform, achieving a better appearance and better aesthetics.

[0082] In some embodiments, along the length direction of the edging 62 , that is, along the X direction, the size of the limiting protrusion 63 is not less than the size of the junction between the rearview mirror 7 and the outer water cut.

[0083] That is to say, the size of the limiting protrusion 63 in the X direction is greater than or equal to the size of the junction of the outer water cut and the rearview mirror 7 in the X direction, so that the limiting protrusion 63 can support the area of ​​the outer water cut below the rearview mirror 7, thereby further enhancing the supporting and limiting effect of the limiting protrusion 63 on the outer water cut in the area cooperating with the rearview mirror 7, making the gap here more uniform, the appearance difference more beautiful, and the appearance quality higher.
