[0003] In related technologies, in order to improve the overall visual effect of the vehicle, a combination of frameless doors and hidden external water-cutting structure is usually adopted to achieve a balance between practicality and aesthetics. However, water ingress is prone to occur, and the waterproof performance and safety of the vehicle cannot be guaranteed to meet the requirements. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide an internal water-cutting structure and a door assembly and vehicle having the same, which can solve the water ingress problem of existing door assemblies.
[0005] To achieve the above-mentioned technical objectives, the first aspect of this utility model provides an inner water cutter structure for connecting a vehicle door, an outer water cutter, and a vehicle window glass. The inner water cutter structure includes an inner water cutter joint, which is connected to the outer water cutter. The inner water cutter joint includes a main body and an abutting part disposed on the main body. The abutting part abuts against the inner panel of the vehicle door, so that a drainage outlet is formed between the inner water cutter joint and the vehicle door.
[0006] In one embodiment, the abutting portion is located at the lower edge of the main body portion and extends from the outer surface of the main body portion in a direction away from the main body portion.
[0007] In one embodiment, the protrusion height of the abutment portion is greater than or equal to 1.5 mm.
[0008] In one embodiment, the inner water cut-off angle further includes a drainage portion, which includes a drainage port located at the upper edge of the main body and a drainage rib extending downward from the inner surface of the main body along the height direction of the main body. The position of the drainage port corresponds to the position of the sidewall at one end of the drainage rib.
[0009] In one embodiment, the angle between the drainage rib and the projection of the drainage rib onto the main body is an acute angle.
[0010] In one embodiment, the inner water cut-off angle further includes a reinforcing portion disposed on the main body portion, the reinforcing portion extending along the height direction of the main body portion.
[0011] In one embodiment, the inner water cut-off angle further includes a connecting portion provided on the main body, the connecting portion being used for fixed connection with the vehicle door.
[0012] In one embodiment, the inner water-cutting structure further includes an inner water-cutting body disposed on the inner side of the window glass, the position of the inner water-cutting body corresponding to the position of the window glass, and the inner water-cutting joint being disposed at at least one end of the inner water-cutting body.
[0013] A second aspect of this utility model provides a vehicle door assembly, including a vehicle door, an outer water cutter, a vehicle window glass, and an inner water cutter structure as described in the above technical solution, wherein the inner water cutter structure is connected to the vehicle door, the outer water cutter, and the vehicle window glass.
[0014] A third aspect of this utility model provides a vehicle including a door assembly as described in the above technical solution.
[0015] By adopting the above technical solution, this utility model has the following beneficial effects:
[0016] This invention, by setting an abutment part on the main body of the inner water cut-off corner and having the abutment part abut against the inner panel of the car door, forms a drainage outlet between the inner water cut-off corner and the car door. Compared with the existing technology that uses a seal to "block" the water ingress problem in the cockpit, this invention not only solves the water ingress problem of frameless car doors by quickly draining the liquid that enters from between the outer water cut-off corner and the car door, but also has significant cost and cycle advantages.
[0017] Furthermore, by providing a drainage section on the main body of the inner water-cutting corner, liquid entering from between the outer water-cutting and the window glass can be quickly discharged, which also helps to improve the waterproof performance of the frameless door.

[0039] The water-cutting structure is a crucial sealing component in the door assembly, and its design directly affects the vehicle's waterproofing, noise reduction, and aesthetics. Currently, an increasing number of new energy vehicles are adopting a combination of frameless doors and concealed external water-cutting structures to improve the overall visual appeal of the door assembly and achieve a lower drag coefficient, thus balancing practicality and aesthetics. However, this combination of frameless doors and concealed external water-cutting structures also presents some problems. For example, the door glass lacks a proper seal, and the matching quality of the concealed external water-cutting structure with the door outer panel flange is challenging, making the vehicle prone to water ingress and compromising its waterproofing performance.
[0040] To address the water ingress issue in existing door assemblies, it is necessary to improve or optimize them.
[0041] Example 1
[0042] Please see Figures 1 to 4An embodiment of the first aspect of this utility model provides an inner water-cutting structure 1 for connecting a vehicle door 2, an outer water-cutting structure 3, and a vehicle window 4. The door 2 can be considered as the left front door of the vehicle, but is not limited thereto. The vehicle window 4 is movably mounted on the door 2. The outer water-cutting structure 3 is fixed between the upper edge of the outer panel of the door 2 and the vehicle window 4, contacting the outer side of the vehicle window 4 to form a first waterproof barrier. The inner water-cutting structure 1 is installed between the upper edge of the inner panel of the door 2 and the vehicle window 4, contacting the inner side of the vehicle window 4 to form a second waterproof barrier. Thus, when the door 2 is closed, because the outer water-cutting structure 3 and the inner water-cutting structure 1 cover the contact area between the top of the door 2 and the vehicle window 4, and because the outer water-cutting structure 3 and the inner water-cutting structure 1 are in close contact with the opposite sides of the vehicle window 4, a double-layer sealing barrier is formed, preventing water, dust, and other foreign objects from entering the vehicle. Furthermore, along the front-rear direction of the vehicle, the inner water-cutting structure 1 contacts the outer water-cutting structure 3 at both the front and rear ends of the window glass 4.
[0043] like Figures 5 to 9 As shown, the inner water-cutting structure 1 includes an inner water-cutting angle 11 and an inner water-cutting body 12. Specifically, the position of the inner water-cutting body 12 corresponds to the position of the vehicle window glass 4, that is, the inner water-cutting structure 1 contacts the vehicle window glass 4 through the water-blocking strip 121 on the inner water-cutting body 12. The inner water-cutting angle 11 is provided at at least one end of the inner water-cutting body 12. Preferably, the inner water-cutting angle 11 is provided at both the front and rear ends of the inner water-cutting body 12. The inner water-cutting angle 11 contacts the outer water-cutting 3 from both the front and rear ends of the vehicle window glass 4. It should be noted that, for the convenience of displaying the relevant structures, the drawings in this application show the relevant structures after the door 2 has been cut along the vertical direction. The inner water-cutting angle 11 includes a main body 111 and an abutment portion 112 formed on the main body 111. The main body 111 is in the shape of a curved panel and is used to connect the door 2, the outer water cutter 3 and the window glass 4. Specifically, its upper edge is connected to the outer water cutter 3 and the window glass 4, and its side edge and lower edge are connected to the door 2.
[0044] like Figure 7 , Figure 8As shown, the abutment portion 112 protrudes from the outer surface of the main body portion 111 toward the direction of the door 2 and abuts against the door 2, so that the inner water-cutting corner 11 and the door 2 cannot be fitted together, and a drain outlet 102 is formed between them. In this way, liquid (such as rainwater) entering from between the outer water-cutting corner 3 and the door 2 can be discharged through the drain outlet 102. Specifically, the abutment portion 112 is formed on the lower edge of the main body portion 111. It should be noted that the outer surface of the main body portion 111 referred to here refers to the surface of the main body portion 111 near the outside of the vehicle. Preferably, the protrusion height of the abutment portion 112 is greater than or equal to 1.5 mm, so that the width of the drain outlet 102 is greater than or equal to 1.5 mm. In this way, when the inner water-cutting corner 11 is installed, liquid flow channels can be formed at the upper and middle parts of the inner water-cutting corner 11 by the sealing strip provided between the inner water-cutting corner 11 and the inner door panel of the door 2. When rainwater enters between the outer water cutter 3 and the door 2, due to the wall adhesion effect and siphon effect, the drain outlet 102 is formed between the inner water cutter angle 11 and the door 2, allowing rainwater to be quickly discharged through the drain outlet 102, which helps to solve the problem of water entering the driver's cabin from between the outer water cutter 3 and the door 2.
[0045] Furthermore, such as Figure 9 As shown, the inner water-cutting angle 11 also includes a drainage section 113. The drainage section 113 is used to drain liquid entering from between the outer water-cutting angle 3 and the window glass 4. Specifically, the drainage section 113 includes a drainage port 114 and a drainage rib 115. The drainage port 114 is a groove-shaped recess on the upper edge end face of the main body 111. The drainage rib 115 is plate-shaped and extends downward from the inner surface of the main body 111 along the height direction of the main body 111. The sidewall of the drainage rib 115 facing the drainage port 114 corresponds to the position of the drainage port 114. Liquid flowing out of the drainage port 114 can flow downward along the sidewall of the drainage rib 115. Preferably, the angle between the drainage rib 115 and the projection of the drainage rib 115 onto the main body 111 is an acute angle. Thus, based on the wall effect and siphon effect, since the drainage port 114 and drainage rib 115 are provided in the flow path of rainwater, when rainwater enters from the gap between the outer water cutter 3 and the window glass 4, the rainwater is quickly discharged through the side walls of the drainage port 114 and the drainage rib 115 to the preset area of the door 2 (such as the wet area of the door sheet metal), and / or, through the outer side walls of the drainage port 114 and the main body 111 to the cavity of the door 2, and then discharged outside the vehicle, which helps to solve the problem of water entering the cabin from between the outer water cutter 3 and the window glass 4.
[0046] Furthermore, the inner water-cutting angle 11 also includes a reinforcing portion 116. Specifically, the reinforcing portion 116 is elongated and formed on the outer surface of the main body 111, extending along the height direction of the main body 111 to enhance the structural strength of the inner water-cutting angle 11. Preferably, there are multiple reinforcing portions 116, and the multiple reinforcing portions 116 are equally spaced.
[0047] Furthermore, the inner water-cutting angle 11 also includes a connecting portion 117. Specifically, the connecting portion 117 is formed on the outer surface of the main body portion 111 and is used to engage with the corresponding mounting hole on the door 2 for fixed connection. Preferably, there are three connecting portions 117, and the three connecting portions 117 are arranged in a triangular shape in space.
[0048] Furthermore, the inner water-cutting body 12 includes a water-retaining strip 121, which may be made of rubber, silicone, or thermoplastic elastomer (TPE). It may also include a fixing structure for maintaining the shape of the water-retaining strip 121, which is made of metal (such as steel or aluminum alloy) or high-strength plastic to provide a better seal when the inner water-cutting body 12 comes into contact with the window glass 4.

[0050] A second aspect of this utility model provides a car door assembly, which includes a car door 2, an outer water cutter 3, a car window glass 4, and an inner water cutter structure 1 as described in Embodiment 1. The inner water cutter structure 1 is connected to the car door 2, the outer water cutter 3, and the car window glass 4, so that the car door assembly has the characteristic of better waterproof performance.
[0051] Example 3
[0052] A third aspect of this utility model provides a vehicle that includes a door assembly as described in Embodiment 2, which makes the vehicle highly safe and provides a better user experience.
