[0037] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0039] In the prior art, the split-opening tailgate includes an upper door and a lower door. A sealing strip is provided around the tailgate opening. The upper door is hinged to the upper edge of the tailgate opening of the vehicle, and the lower door is hinged to the lower edge of the tailgate opening. A seam is formed at the joint of the upper door and the lower door. A sealing strip is also provided at the seam. Specifically, it can be provided on the side of the upper door facing the lower door or on the side of the lower door facing the upper door. The sealing strip at the seam has corner structures at both ends that seal the junction of the upper door, the lower door, and the tailgate opening.

[0040] Because the corner joint structure itself has a certain thickness, when part of the corner joint structure is pressed between the sealing strip of the upper half door and the rear door opening, a triangular gap will be formed between the end of the corner joint structure and the sealing strip of the rear door opening. Furthermore, when part of the corner joint structure is pressed between the upper half door and the lower half door, the seal between the upper half door and the lower half door is not complete, and a gap will also be formed between the side of the corner joint structure and the lower half door. Water can easily flow into the car through these two gaps.

[0041] Therefore, the waterproofing effect of the sealing strip structure in the existing technology is poor.

[0042] To overcome the deficiencies in the prior art, this application provides a sealing strip structure and vehicle. The sealing strip structure is used on the sealing surface of the rear door. The sealing strip structure includes a sealing strip body and a corner structure disposed at the end of the sealing strip body. The corner structure is provided with a water-blocking part and a water-guiding part. By providing the water-blocking part and the water-guiding part, the water-blocking part can block part of the water flow on the corner structure, preventing water from flowing to the inside of the sealing surface, and the water-guiding part can guide another part of the water flow on the corner structure to the outside of the sealing surface. Through the cooperation of the water-blocking part and the water-guiding part, the water flow from the outside of the sealing surface to the inside of the sealing surface can be reduced, and the water flowing to the corner structure of the sealing strip can be guided to the outside of the sealing surface, thereby improving the waterproof sealing performance of the sealing strip.

[0043] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0044] Reference Figures 1 to 4 As shown, this application embodiment provides a sealing strip structure, including:

[0045] The sealing strip body is used to be installed on the closed surface of the rear door body 400;

[0046] Angle joint structure 100 is provided at the end of the sealing strip body, and the angle joint structure 100 is provided with:

[0047] Water-blocking part 200 is used to block at least part of the water on the corner structure 100 from flowing into the inside of the closed surface;

[0048] Water guiding part 300 is located on one side of water blocking part 200. Water guiding part 300 is used to guide at least part of the water on corner structure 100 to the outside of the closed surface.

[0049] It is understood that the corner joint structure 100 is used to be set at the end of the sealing strip body so that the sealing strip connects with the corners of other structures. In the sealing strip structure provided in the embodiments of this application, the corner joint structure 100 can be integrally formed with the sealing strip body, or it can be set as a separate structural component connected to the end of the sealing strip body. The two corner joint structures 100 at both ends of the sealing strip body are symmetrical to each other. The following description only takes the case of one end of the corner joint structure 100 being applied to a top-and-bottom split-opening rear door as an example to illustrate this application.

[0050] The corner joints are located at both ends of the sealing strip body to form a complete sealing strip. The sealing strip structure is installed on the upper half of the split-opening rear door (rear door body 400) and is located on the edge of the upper half of the rear door (rear door body 400) facing the lower half of the door, i.e., on the closing surface of the rear door body 400. Specifically, the sealing strip body is arranged horizontally to ensure the sealing at the seam between the upper half of the door (rear door body 400) and the lower half of the door. The two corner joints 100 are bent relative to the sealing strip body and arranged vertically to ensure the sealing at the junction of the upper half of the door (rear door body 400), the lower half of the door, and the rear door opening. The upper half of the door is the rear door body 400, and the lower half of the door and the rear door opening can be considered as the parts to be sealed, to be sealed with the closing surface of the upper half of the door.

[0051] It should be noted here that, as Figure 4 As shown, the left side of the corner structure 100 corresponds to the upper half door (rear door body 400), the lower half door and the outer side of the rear door opening, which is also the outer side of the vehicle; the right side of the corner structure 100 corresponds to the upper half door (rear door body 400), the lower half door and the inner side of the rear door opening, which is also the inner side of the vehicle.

[0052] The corner structure 100 is provided with a water-blocking part 200 and a water-guiding part 300. The corner structure 100 is connected to the sealing strip body and is provided on the side of the upper half door (rear tailgate 400) facing the inside of the vehicle, that is, on the sealing surface. The water-blocking part 200 and the water-guiding part 300 are both located on the side of the corner structure 100 facing the lower half door and the door opening. Thus, when the upper half door (rear tailgate 400) and the lower half door are closed, the corner structure 100 can be pressed between the upper half door (rear tailgate 400), the lower half door and the door opening, and both the water-blocking part 200 and the water-guiding part 300 are pressed tightly against the lower half door and the door opening. Thus, when water flows from the upper half of the door (back door body 400) and the lower half of the door away from the door opening to the corner structure 100, some of the water will be blocked outside the door opening by the water-blocking part 200 and will not be able to flow into the door opening. The other part of the water that is not blocked in time by the water-blocking part 200 will be further guided out to the outside of the door opening by the water-guiding part 300.

[0053] Therefore, the sealing strip structure provided in this application embodiment is used to be installed on the sealing surface of the rear door body 400. The sealing strip structure includes a sealing strip body and a corner structure 100 provided at the end of the sealing strip body. The corner structure 100 is provided with a water-blocking part 200 and a water-guiding part 300. By providing the water-blocking part 200 and the water-guiding part 300, the water-blocking part 200 can block part of the water flow on the corner structure 100, preventing the water flow to the inside of the sealing surface, and the water-guiding part 300 can guide another part of the water flow on the corner structure 100 to guide the water flow to the outside of the sealing surface. Through the cooperation of the water-blocking part 200 and the water-guiding part 300, the water flow from the outside of the sealing surface to the inside of the sealing surface can be reduced, and the water flowing to the corner structure 100 of the sealing strip can be guided to the outside of the sealing surface, thereby improving the waterproof sealing performance of the sealing strip.

[0054] In some embodiments, refer to Figures 1 to 4 As shown, the water guiding part 300 includes at least one water guiding rib 310, and the extending direction of the at least one water guiding rib 310 is inclined toward the water blocking part 200.

[0055] It is understandable that the water guide rib 310 is set so that the water flow can flow smoothly along the extension direction of the water guide rib 310. This makes the extension direction of the water guide rib 310 inclined towards the water blocking part 200, so as to form an angle with the extension direction of the corner structure 100. In this way, when setting the extension direction of the water guide rib 310, the water guide rib 310 extends towards the outer side of the upper half door (rear door body 400), the lower half door and the door opening. That is, after the water guide rib 310 is installed, it can extend towards the outside of the vehicle, so that the water flow can be smoothly guided to the outside of the vehicle by the water guide rib 310.

[0056] And refer to Figure 5 As shown, the water guide rib 310 is inclined relative to the surface of the corner structure 100.

[0057] It is understandable that when the upper and lower doors are closed, the sealing strip structure is compressed to ensure the seal between the upper and lower doors and the door opening. In this way, the water guide rib 310 is inclined relative to the surface of the corner structure 100, specifically inclined towards the outside of the vehicle. When the water guide rib 310 is compressed and deformed, it can be stably deformed towards the outside of the vehicle, so that the water guide rib 310 still retains the water guiding function after deformation, thereby ensuring that the waterproof effect of the sealing strip structure is always effective.

[0058] For example, the water guide rib 310 may be inclined at 10° relative to the surface of the corner structure 100.

[0059] Furthermore, refer to Figures 1 to 5 As shown, at least two water guide ribs 310 are spaced apart, and a water guide groove 320 is provided between two adjacent water guide ribs 310. The bottom of the water guide groove 320 is smoothly connected to the surface of the corner structure 100.

[0060] It is understandable that setting two or more water-guiding ribs 310 can further improve the waterproof effect of the sealing strip structure. The water-guiding ribs 310 formed between two adjacent water-guiding ribs 310 can ensure that water can flow out of the vehicle stably and smoothly within the water-guiding groove 320, resulting in a better waterproof effect.

[0061] For example, the depth of the water guide channel 320 depends on the height of the water guide rib 310. The water guide rib 310 is set to a height of 4 mm, and the water guide channel 320 is further recessed by at least 1 mm relative to the surface of the corner structure 100, so that the depth of the water guide rib 310 is at least 5 mm. Furthermore, the length of the water guide channel 320 depends on the length of the water guide rib 310. The water guide rib 310 is set to a length of 25 mm, and the water guide rib 310 extends at least 10 mm towards the second section 120, so that the bottom of the water guide channel 320 extends at least 10 mm towards the second section 120, making the length of the water guide channel 320 at least 35 mm. This allows for a smooth transition and connection with the surface of the corner structure 100, facilitating the flow of water from the surface of the corner structure 100 into the water guide channel 320, enabling the water guide channel 320 to smoothly guide water to the outside of the vehicle. Additionally, the thickness of the water guide rib 310 can be set to 3 mm to improve its structural strength.

[0062] Furthermore, in some embodiments, reference is made to Figures 1 to 4 As shown, the water-blocking part 200 and each water-guiding rib 310 are arranged sequentially at intervals from one side of the corner structure 100 along the other side of the corner structure 100.

[0063] By sequentially and intermittently arranging water-blocking parts 200 and water-guiding ribs 310 on one side of the corner structure 100 to the other side, the distribution of water-guiding parts 300 and water-blocking parts 200 is made more reasonable and compact. Specifically, the water-blocking parts 200 are located on the outer side of the corner structure 100 facing the vehicle, which can pre-block some water flow into the water guide channel 320, reduce the water guide volume of the water guide channel 320, and prevent excessive water in the water guide channel 320 from overflowing into the vehicle.

[0064] In other embodiments, a water-blocking part 200 may be provided on the side of the corner structure 100 facing the inside of the vehicle so that the water overflowing from the water guide channel 320 is intercepted by the water-blocking part 200. This application does not limit this.

[0065] Furthermore, referring to Figures 1 to 4 As shown, at least one end of the water guide rib 310 is opposite to the side of the water blocking part 200.

[0066] Specifically, the end of the water guide 310 adjacent to the water-blocking part 200 is set opposite to the side of the water-blocking part 200, thereby using the side of the water-blocking part 200 to block at least one water guide groove 320, so that the water in the water guide groove 320 can flow smoothly and stably downward to the outside of the closed surface, with good sealing and waterproofing effect and compact structure.

[0067] Among them, reference Figures 1 to 4 As shown, the water-blocking part 200 is a water-blocking plate.

[0068] This design allows for a simpler and more compact structure for the water-blocking section 200, reduces the processing cost of the sealing strip structure, and ensures the waterproof effect of the sealing strip structure.

[0069] Furthermore, the length of the water-blocking plate can be set to at least 18 mm, and the height can be set to at least 11.5 mm; this application does not impose any limitations on this.

[0070] In some embodiments, refer to Figures 1 to 3 As shown, the corner structure 100 includes:

[0071] The first segment 110 is used to connect with the sealing strip body and to the first area of ​​the sealing surface;

[0072] The second segment 120 is located at the end of the first segment 110 away from the sealing strip body, and the second segment 120 is used to connect with the second area of ​​the sealing surface;

[0073] Both the water-blocking part 200 and the water-guiding part 300 are provided on one of the first section 110 and the second section 120, and are connected to the other.

[0074] It is understandable that the corner structure 100 is set into two parts, the first segment 110 and the second segment 120, so that the corner structure 100 can be better pressed into the lower half of the door and the door opening respectively. The water-blocking part 200 and the water-guiding part 300 are both distributed on the first segment 110 and the second segment 120 to effectively ensure the sealing performance of the sealing strip structure.

[0075] The first segment 110 is connected to the sealing strip body and to the first area of ​​the sealing surface. The first area is opposite to the lower half of the door, so that the first segment 110 can be pressed against the lower half of the door. The second segment 120 is disposed at the end of the first segment 110 and is connected to the second area of ​​the sealing surface. The second area is opposite to the door opening, so that the second segment 120 can be pressed against the door opening. In other embodiments, the orientation of the corner structure 100 can also be adjusted to make the first segment 110 press against the door opening and the second segment 120 press against the lower half of the door. This application does not limit this.

[0076] In this embodiment, the water-blocking part 200 and the water-guiding part 300 are mainly disposed on the first section 110 and partially extend to the second section 120 to connect with the second section 120, so as to improve the waterproof effect between the upper half door (back door body 400) and the lower half door, and to a certain extent ensure the waterproof effect between the upper half door (back door body 400) and the door opening. In other embodiments, the water-blocking part 200 and the water-guiding part 300 may also be disposed on the second section 120 and connected to the first section 110. This application does not limit this.

[0077] In specific implementation, refer to Figures 1 to 3 As shown, the first segment 110 is a cylindrical segment, and the second segment 120 is a wedge-shaped segment, with the large end of the wedge-shaped segment connected to the cylindrical segment.

[0078] It is understandable that the sealing strip body is usually a relatively regular cylindrical strip. Therefore, setting the first segment 110 as a cylindrical segment can make the connection between the sealing strip body and the corner structure 100 smoother, reduce the step difference between the sealing strip body and the corner structure 100, and ensure the sealing effect between the sealing strip body and the corner structure 100.

[0079] By setting the second segment 120 as a wedge-shaped segment and connecting the large end of the wedge-shaped segment to the first segment 110, it is possible to ensure a smooth transition between the wedge-shaped segment and the cylindrical segment. It is also possible to ensure that the inclined surface of the wedge-shaped segment can smoothly connect the profile of the first segment 110 and the surface of the rear door 400, making the transition between the sealing strip structure and the rear door 400 smooth. This also reduces the step difference between the sealing strip structure and the rear door 400, and prevents water from flowing into the vehicle along the step as much as possible, further ensuring the sealing performance of the sealing strip structure.

[0080] Furthermore, in some embodiments, reference is made to Figures 1 to 4As shown, the edge of the second segment 120, which is away from the first segment 110, is inclined toward the outside of the closed surface.

[0081] It is understandable that this design allows for a smoother transition between the second section 120 and the rear door 400. Furthermore, when water flows from the upper half of the door (rear door 400) between the top and the door opening to the triangular gap at the sealing strip structure, the inclined edge of the second section 120 can guide some of the water to the outside of the vehicle, thus improving the vehicle's waterproofing performance.

[0082] For example, the height difference between the two ends of the upper edge of the second segment 120 can be set to 10mm, but this application does not limit it.

[0083] The above is only an example of the dimensions of the sealing strip structure. The specific dimensions of the sealing strip structure can be adjusted according to the performance parameters of the selected materials, the installation location and working conditions, and the waterproofing requirements. This application does not impose any restrictions on this.

[0084] This application also provides a vehicle, including a vehicle body and a sealing strip structure as described in any of the above embodiments disposed on the vehicle body.

[0085] The sealing strip structure has been described in detail in the above embodiments and will not be repeated here.

[0086] The vehicle provided in this application embodiment has a sealing strip structure. The sealing strip structure is used to install on the closed surface of the rear door 400. The sealing strip structure includes a sealing strip body and a corner structure 100 provided at the end of the sealing strip body. The corner structure 100 is provided with a water-blocking part 200 and a water-guiding part 300. By providing the water-blocking part 200 and the water-guiding part 300, the water-blocking part 200 can block part of the water flow on the corner structure 100 to prevent the water flow to the inside of the closed surface, and the water-guiding part 300 can guide another part of the water flow on the corner structure 100 to guide the water flow to the outside of the closed surface.

[0087] By combining the water-blocking part 200 and the water-guiding part 300, the water flow from the outside of the sealing surface to the inside of the sealing surface can be reduced, and the water flowing to the corner structure 100 of the sealing strip can be guided to the outside of the sealing surface, thereby improving the waterproof sealing performance of the sealing strip.
