[0045] Automotive weatherstripping is a crucial component of automobiles, widely used in doors, windows, engine compartments, and trunks, providing sound insulation, dustproofing, water resistance, and shock absorption. The water-cutting structure on car doors is a type of weatherstripping, positioned between the window glass and the door frame. When the window is raised or lowered, the water-cutting structure gently wipes away water droplets, fog, and dust from the glass, resulting in a clearer view.

[0046] In related technologies, the sheet metal parts of the car door are welded with brackets for mounting the water-cutting structure, and the water-cutting structure and the brackets are detachably connected. The installation of the brackets increases the dimensional chain during the assembly process. Machining deviations of the brackets, assembly deviations with the sheet metal parts, and assembly deviations between the brackets and the water-cutting structure will all affect the final assembly effect of the water-cutting structure, easily leading to quality problems such as warping of the water-cutting structure ends, vibration and abnormal noise between the water-cutting structure and the brackets, and poor sealing between the water-cutting structure and the glass.

[0047] In addition, the production of the bracket requires the development of corresponding molds, and the welding of the bracket to the main body of the car door requires the development of corresponding tooling, which increases the production cost of the water-cutting structure. Furthermore, due to the welding process involved, a series of tedious procedures such as positioning, rust removal, welding, grinding, and inspection are required. These procedures are not only time-consuming and labor-intensive, but also increase the difficulty of quality control during the production process.

[0048] To address the aforementioned problems, the first aspect of this application proposes a water-cutting structure, referring to... Figures 1 to 2 As shown, the water-cutting structure is directly installed on the door body 300 without the need for a bracket. Specifically, the water-cutting structure includes a water-cutting body 100 and a corner fitting body 200. The water-cutting body 100 is used to abut against the window glass. The water-cutting body 100 is typically made of a soft material and integrally injection molded to ensure a good fit with the window glass without scratching it. The corner fitting body 200 is also made of a soft material and integrally injection molded. It should be noted that in this application, the water-cutting body 100 is connected to the door body 300 through the corner fitting body 200. Therefore, the corner fitting body 200 needs to have higher structural strength than the water-cutting body 100 to improve the stability of the water-cutting body 100 installed on the door body 300. Thus, the material hardness of the corner fitting body 200 is greater than that of the water-cutting body 100.

[0049] The corner connector 200 includes a first connecting portion 210 and a second connecting portion 220. The first connecting portion 210 is directly connected to the water-cutting body 100, and the second connecting portion 220 is used to directly connect to the door body 300. It should be noted that the first connecting portion 210 and the water-cutting body 100 can be connected as an integral structure through methods such as plug-in fitting, snap-fit ​​fitting, or heat-fusion connection. In this embodiment, the first connecting portion 210 and the water-cutting body 100 are formed as an integral structure through secondary injection molding. The second connecting portion 220 and the door body 300 can be connected as an integral structure through methods such as plug-in fitting or threaded connection. The door body 300 is provided with a structure that mates with the second connecting portion 220. In this embodiment of the application, the second connecting part 220 and the door body 300 are detachably connected by a snap-fit ​​engagement. The second connecting part 220 is specifically a buckle 221. The door body 300 is provided with a mounting hole 310. The buckle is snapped into the mounting hole 310 to install the water cutter body 100 onto the door body 300.

[0050] Based on the above, in this embodiment of the application, the water-cutting structure includes a water-cutting main body 100 and a corner-connecting main body 200 connected as one unit. Compared with the prior art, in which the water-cutting structure is installed on the bracket through the corner-connecting main body 200 and then transferred to the door body 300 through the bracket, the corner-connecting main body 200 of this application is directly installed on the door body 300 without the need to set up a bracket for transfer.

[0051] Therefore, the water-cutting structure of this embodiment, by eliminating the bracket, shortens the dimensional chain in the water-cutting structure assembly process, reduces the assembly deviation of the water-cutting structure installed on the door body 300, and improves assembly accuracy. Furthermore, the reduction in the number of components in the water-cutting structure helps lower costs and contributes to vehicle weight reduction, thereby increasing the vehicle's driving range. Moreover, the detachable connection between the water-cutting structure and the door body 300 is simpler in process steps and more efficient in assembly compared to welding in related technologies.

[0052] In some embodiments, the water-cutting body 100 and the corner fitting body 200 are connected into an integral structure through a secondary injection molding process, thereby the first connecting part 210 of the corner fitting body 200 is embedded in the interior of the water-cutting body 100, thereby realizing the connection between the corner fitting body 200 and the water-cutting body 100.

[0053] In some embodiments, such as Figure 4 As shown, the lower end of the water-cutting body 100 of this application extends into a first main body portion 110 and a second main body portion 120. The first main body portion 110 and the second main body portion 120 are arranged side by side, and a first gap 130 for connection with the door body 300 is defined between the first main body portion 110 and the second main body portion 120. It should be noted that in some embodiments, the door body 300 includes at least one sheet metal piece. On the one hand, the sheet metal piece is provided with a structure for cooperating with the second connecting portion 220 of the corner body 200. On the other hand, its top end extends into the first gap 130. The first main body portion 110 and the second main body portion 120 are respectively clamped on both sides of the sheet metal piece to achieve pre-fixation of the water-cutting body 100. In other embodiments, the door body 300 includes multiple sheet metal pieces, and two sheet metal pieces are respectively connected to the corner body 200 and the water-cutting structure.

[0054] Among them, such as Figure 3 As shown, a first connecting hole 111 is provided at one or both ends of the water-cutting body 100 along its length. The first connecting hole 111 can be formed by injection molding or by punching on the water-cutting body 100. The first connecting hole 111 penetrates the first body portion 110 and communicates with the first gap 130. The first connecting hole 111 can be a circular hole or a square hole, as shown in the figure. Figure 3 In the illustrated embodiment, a square first connecting hole 111 is punched out along an L-shaped path at the end of the first main body 110. The length of the first connecting hole 111 is preferably 40mm to 80mm, and the width is preferably 8mm to 15mm. A first connecting part 210 passes through the first connecting hole 111 and is connected to the second main body 120. Specifically, the first connecting part 210 fills the first connecting hole 111 and the first gap 130 corresponding to the first connecting hole 111.

[0055] Furthermore, for ease of description, the first main body portion 110 on the outer periphery of the first connecting hole 111 is named the first edge. When the first connecting hole 111 is as follows... Figure 3 When cutting a square groove as shown, the first edge includes the edge as shown in the figure. Figure 3 The first sub-edge 113 extending in the front-back direction and along Figure 3 The second sub-edge 114 extending vertically is shown, as... Figure 4 As shown, the first connecting part 210 has a first wall surface 214 and a second wall surface 215 that are perpendicular to each other. Both the first wall surface 214 and the second wall surface 215 are provided with a first groove 211. The first sub-edge 113 is embedded in the first groove 211 of the first wall surface 214, and the embedding depth is preferably 2mm to 5mm. The second sub-edge 114 is embedded in the first groove 211 of the second wall surface 215, and the embedding depth is preferably 5mm to 10mm.

[0056] Furthermore, based on the foregoing, the top of the sheet metal part of the door body 300 is inserted into the first gap 130 of the water-cutting body 100, so that the water-cutting body 100 is initially fixed to the sheet metal part. Figure 4 As shown, a first abutting protrusion 112 is provided on the wall surface of the first main body 110 near the second main body 120. The first abutting protrusion 112 extends into the first gap 130. When the sheet metal part is inserted into the first gap 130, the first abutting protrusion 112 can undergo elastic deformation and abut against the side wall of the sheet metal part, thereby enhancing the interaction force between the water-cutting main body 100 and the sheet metal part, so as to improve the stability of the water-cutting main body 100 connected to the sheet metal part.

[0057] Additionally, refer to Figure 5 The first connecting portion 210 includes a third main body portion 212 and a fourth main body portion 213 defining a first groove 211. The third main body portion 212 and the fourth main body portion 213 are arranged side by side and spaced apart. When the first edge is embedded in the first groove 211, the fourth main body portion 213 is also embedded in the first gap 130 between the first main body portion 110 and the second main body portion 120. The fourth main body portion 213 located in the first gap 130 covers a portion of the first abutting protrusion 112, thereby increasing the contact area between the first connecting portion 210 and the water-cutting body 100, thereby improving the stability of the connection between the water-cutting body 100 and the corner body 200. The remaining portion of the first abutting protrusion 112 is used to abut against the sheet metal part to achieve a stable connection of the water-cutting body 100 on the sheet metal part.

[0058] Similarly, a second abutment protrusion (not shown in the figure) may also be provided on the wall surface of the second main body 120 near the first main body 110, and the fourth main body 213 located in the first gap 130 covers part of the second abutment protrusion. It should be explained that the "covering" mentioned above means that the fourth main body 213 forms a receiving groove for accommodating the first abutment protrusion 112 and / or the second abutment protrusion during the injection molding process, and the first abutment protrusion 112 and / or the second abutment protrusion are embedded in the receiving groove and connected to the fourth main body 213.

[0059] Furthermore, the first groove 211 has two side walls that clamp onto both sides of the first main body 110, and a bottom wall located between the two side walls, the bottom wall being provided with a first flange (not shown in the figure). The groove wall of the first connecting hole 111 is provided with a second groove 1111, such as... Figure 3 and Figure 4 As shown, the top wall and side wall of the first connecting hole 111 are both provided with a second groove 1111. When the water cutting body 100 is injection molded onto the corner body 200, the first flange is embedded in the second groove 1111 to increase the contact area between the corner body 200 and the water cutting body 100.

[0060] In some embodiments, the door body 300 is provided with a mounting hole 310, and the second connecting portion 220 includes a buckle 221, which can pass through the mounting hole 310 to engage with the door body 300. Figure 5 As shown, the buckle 221 has a tapered structure with a taper between 30° and 45°. The outer diameter of the buckle 221 gradually decreases as it is inserted into the mounting hole 310, so that the smaller end of the buckle 221 can pass through the mounting hole 310 first, guiding the insertion. The outer diameter of the larger end of the buckle 221 is 1.5mm to 2.5mm larger on each side than the outer diameter of the mounting hole 310, making it less likely to come out after the larger end of the buckle 221 passes through the mounting hole 310.

[0061] To facilitate the large end of the buckle 221 passing through the mounting hole 310, multiple deformation grooves 2211 are provided at intervals along the circumference of the buckle 221. The deformation grooves 2211 extend along the circumference of the buckle 221 and penetrate through the buckle 221, so that the buckle 221 forms multiple spaced elastic flaps 2212. Since the through-hole setting of the deformation grooves 2211 reduces the structural strength of the buckle 221, and the deformation grooves 2211 can accommodate the elastic deformation of the elastic flaps 2212 when they abut against the hole wall of the mounting hole 310, the buckle 221 can switch to a deformed state during the process of passing through the mounting hole 310. In this state, the outer diameter of the buckle 221 is smaller than the hole diameter of the mounting hole 310. When the buckle 221 passes through the mounting hole 310, its elastic flap 2212 returns to the initial state. In the initial state, the outer diameter of the buckle 221 is larger than the diameter of the mounting hole 310, so that the buckle 221 cannot be dislodged from the mounting hole 310, thereby achieving a firm connection between the second connecting part 220 and the door body 300.

[0062] In such Figure 8 In the illustrated embodiment, the snap fastener 221 has four deformation grooves 2211 evenly distributed along its circumference. The width of each deformation groove 2211 along the circumference of the snap fastener 221 accounts for 8% to 12% of its circumference. It should be noted that, to ensure the snap-fit ​​strength, the sum of the widths of all deformation grooves 2211 along the circumference of the snap fastener 221 cannot exceed 50% of its circumference.

[0063] Furthermore, such as Figure 6 and Figure 7 As shown, the second connecting part 220 also includes a locking post 222 and a connecting section 223. The locking post 222 protrudes from the side wall of the first connecting part 210, and the connecting section 223 is disposed at the end of the locking post 222, and connects the buckle 221 and the locking post 222 respectively. Figure 7 As shown, the outer diameter of the connecting section 223 is smaller than the outer diameter of the locking post 222 and smaller than the outer diameter of the large end of the buckle 221. The locking post 222 and the buckle 221 define a second gap 224 for accommodating the edge of the mounting hole 310. After the buckle 221 passes through the mounting hole 310, the door body 300 is fitted onto the connecting section 223 and clamped by the large end face of the buckle 221 and the end face of the locking post 222, forming a stable snap-fit ​​structure to ensure that the door body 300 is tightly connected to the water-cooling body 100.

[0064] Additionally, a third abutment protrusion 2221 is provided on the end face of the latch 222 near the buckle 221. This third abutment protrusion 2221 extends into the second gap 224 and is configured to elastically deform to abut against the door body 300. It is understood that the third abutment protrusion 2221 can be a dot-like protrusion distributed on the end face of the latch 222, or it can be like... Figure 5 or Figure 8The linear protrusion shown surrounds the end face of the retaining post 222, increasing the contact area and improving the abutment effect. The elastic deformation of the third abutment protrusion 2221 further enhances the stability of the snap-fit ​​structure, ensuring that the door body 300 and the water-cutting body 100 always maintain a tight fit under various road conditions, and effectively preventing rainwater and dust from entering the interior of the door body 300 through the mounting hole 310, thereby improving the overall sealing performance and ride comfort of the vehicle.

[0065] Furthermore, the width of the linear protrusions is 0.5mm to 1mm to balance elastic deformation capacity and support capacity.

[0066] In addition, to ensure even force distribution on the locking post 222, the second connecting part 220 also includes reinforcing ribs 230, such as... Figure 8 As shown, the second connecting portion 220 includes three reinforcing ribs 230, each with a width of 2mm to 4mm. One end of each reinforcing rib 230 is connected to the retaining post 222, and the other end extends to the edge of the first connecting portion 210. The number of reinforcing ribs 230 can be adjusted according to actual needs, such as... Figure 8 In the embodiment shown, a reinforcing rib 230 is provided above, in front of and behind the locking post 222. Each reinforcing rib 230 and the locking post 222 form a triangular support structure, which effectively disperses external forces and prevents the locking post 222 from deforming.

[0067] A second aspect of this application provides a vehicle door assembly, which includes a door body 300 and a water-cutting structure mentioned in any of the above embodiments. The door body 300 has a mounting hole 310, and a second connecting portion 220 of the water-cutting structure passes through the mounting hole 310 to connect the water-cutting structure to the door assembly. By eliminating the brackets in related technologies, the door assembly is made lighter and the number of components is reduced, which helps to improve vehicle range while reducing the manufacturing cost of the door assembly.

[0068] In addition, compared with welding brackets on the door body 300, the hole opening precision in the door body 300 of this application embodiment is higher, which can effectively reduce manufacturing deviations. The high-precision hole opening process ensures the precise docking of the water-cutting structure and the door body 300, improves assembly efficiency, reduces later maintenance costs, and further enhances the overall performance and reliability of the door assembly.

[0069] Mounting hole 310 can be as follows: Figure 2 The circular hole shown can also be a square hole, an oval hole, or a hole of other shapes, as long as it can match the second connecting part 220. The mounting hole 310 is preferably a circular hole, and the inner diameter of the circular hole is preferably φ7mm to φ9mm.

[0070] The third aspect of this application proposes a vehicle that includes the door assembly mentioned in the above embodiments. The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large semi-trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle. Since the vehicle in this aspect includes the door assembly of the above embodiments, it has the beneficial effects described in the above embodiments, which will not be repeated here.

[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
