Description

Technical Field

[0001] This utility model relates to the field of door water cutting technology, and in particular to a door water cutting installation structure and vehicle. Background Technology

[0002] In automotive door sealing systems, the external water cutter is a core component for achieving rainwater blocking, dust protection, and wind noise control. Its installation scheme is directly related to the door manufacturing process and its compatibility.

[0003] Among the relevant technologies, there are two types of hidden water cutter implementation solutions: one type requires first welding the sheet metal bracket to the door sheet metal, and then inserting the outer water cutter into the bracket. This solution has great limitations on the door edge wrapping process. In order to avoid welding the bracket, the door must use a more expensive mold edge wrapping process, resulting in high manufacturing costs. The other type is that the outer water cutter has a built-in buckle, which is fixed to the door sheet metal by snapping. However, the buckle installation requires sufficient space and no window frame to block it. It is only suitable for frameless doors. For framed doors, the window frame will occupy the installation space and hinder the snapping operation, resulting in difficult installation and unstable sealing effect. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a door water-cutting installation structure and vehicle, so as to solve the problem that the hidden water-cutting implementation scheme in the related technology has great limitations on the edge-wrapping process and cannot be adapted to both framed and frameless doors at the same time.

[0005] To solve the above problems, this utility model is implemented as follows: In a first aspect, embodiments of this application provide a door water-cutting mounting structure, the door water-cutting mounting structure comprising: a door sheet metal assembly and an outer water-cutting device, the door sheet metal assembly comprising a door outer panel assembly and a water-cutting mounting plate; the door outer panel assembly having an insertion hole and a first through hole, the water-cutting mounting plate having an insertion tongue and a second through hole; along the height direction of the door, the insertion tongue engages with the insertion hole, the first through hole and the second through hole are fastened by a fastening assembly; the outer water-cutting device is connected to the water-cutting mounting plate.

[0006] This door water-cutting installation structure achieves pre-positioning through the insertion of the tongue and the hole, coupled with the rigid connection of the fastening components. This avoids the need for additional welding of sheet metal brackets, breaks through the limitations of door edging process, reduces manufacturing costs, and does not rely on the door window frame structure. It can be adapted to both framed and frameless doors, improving versatility. At the same time, the dual fixing method can ensure the stability of the external water-cutting installation and effectively perform the sealing and water-blocking function.

[0007] Optionally, the door outer panel assembly includes a waistline reinforcement plate and a door outer panel; the door outer panel is connected to the waistline reinforcement plate, and the insertion hole and the first through hole are formed on the waistline reinforcement plate.

[0008] Instead of directly opening the insertion hole and the first through hole on the waistline reinforcement plate, the structural strength of the waistline reinforcement plate can be utilized to avoid localized weakening of the door outer panel due to the opening, thus ensuring the overall structural stability of the door. In addition, the high flatness and fixed assembly position of the waistline reinforcement plate can provide a precise benchmark for the opening, reduce hole position deviation, improve the fitting accuracy with the water-cutting mounting plate, and simplify the processing flow of the door outer panel.

[0009] Optionally, the waistline reinforcement plate includes a fitting section and a connecting section; the fitting section is fitted to the outer door panel, one end of the fitting section is connected to the edge of the outer door panel to form a edging structure, the connecting section has a preset bending angle with the fitting section, and the insertion hole and the first through hole are opened in the connecting section.

[0010] The waistline reinforcement plate's fitting section is bonded to the outer door panel to form an edge-wrapping structure, which not only enhances the door's edge strength but also seals the joint gaps, improving waterproofing and dustproofing. The preset bending angle between the connecting section and the fitting section allows the connecting section to offset relative to the outer door panel, providing independent assembly space for the water-cutting mounting plate and avoiding structural interference. Positioning the insertion hole and the first through hole on the connecting section also ensures that the water-cutting installation position more closely matches the sealing requirements of the external water-cutting system, guaranteeing sealing performance.

[0011] Optionally, the water-cutting mounting plate includes a mounting section, an opening section, and a plug-in section; along the height direction of the vehicle door, one end of the mounting section is connected to the external water-cutting device, and the other end is connected to the opening section, the other end of the opening section is connected to the plug-in section, and the other end of the plug-in section is provided with the plug-in tongue; the second through hole is provided on the opening section, the opening section and the mounting section have a preset bending angle, and the opening section fits into the connecting section.

[0012] The segmented structure of the water-cutting mounting plate can be designed in various shapes to meet the assembly requirements of the external water-cutting section and the waistline reinforcement plate, improving adaptability. The preset bending angles of the mounting section and the opening section allow the external water-cutting section to fit the outer contour of the door, ensuring a good seal and avoiding interference. The fit between the opening section and the connecting section increases the contact area and improves connection stability, while the plug tongue of the plug section can achieve pre-positioning, facilitating subsequent fastening assembly, thus optimizing overall assembly accuracy and structural reliability.

[0013] Optionally, the end of the plug segment connected to the opening segment has a connecting portion; the connecting portion is an arc-shaped groove formed by recessing along the thickness direction of the door, one end of the connecting portion is connected to the opening segment, and the other end of the connecting portion is connected to the plug tongue.

[0014] The arc-shaped groove connection between the plug section and the opening section can reserve buffer space in the thickness direction of the door to avoid rigid compression caused by door deformation or assembly errors, reducing the risk of breakage. The arc-shaped transition structure can disperse vibration stress and pressure transmitted by the external water shear, improving the overall strength of the water shear mounting plate. Optionally, along the height direction of the door, the height of the outer water cutter does not exceed the height of the outer door panel.

[0015] Limiting the height of the outer water cutter along the door height direction to not exceed the outer door panel allows the outer water cutter to be naturally concealed by the outline of the outer door panel, achieving a hidden design. At the same time, keeping the outer water cutter from extending beyond the outer door panel reduces direct contact with airflow during driving, lowers wind noise, and also avoids friction and collision with other body parts (such as roof trim and door sill trim), extending the service life of the outer water cutter.

[0016] Optionally, the fastening assembly includes a nut and a bolt; the nut is fixed at the first through hole, and the bolt passes through the second through hole and the first through hole before connecting to the nut.

[0017] The fastening assembly uses a combination of nuts and bolts, with the nut pre-fixed at the first through hole. This eliminates the need for simultaneous alignment of the nut and through hole in a confined space, simplifying the assembly process and improving efficiency. The bolt, passing through two through holes, connects to the nut, creating an axial tightening force along the door's thickness. This ensures a tight fit between the water-cutting mounting plate and the outer door panel assembly, preventing loosening due to vibration. Furthermore, the threaded connection is detachable for easy future maintenance.

[0018] Optionally, the door sheet metal assembly further includes a door inner panel assembly, and the door water cutter mounting structure further includes an inner water cutter; along the thickness direction of the door, the door inner panel assembly is disposed on the side of the water cutter mounting plate away from the door outer panel assembly, and the inner water cutter is connected to the door inner panel assembly.

[0019] The addition of an inner door panel assembly to the door sheet metal assembly forms a complete door frame with the outer door panel assembly, enhancing the overall structural strength of the door. It also provides a stable mounting base for the inner water cutter. By placing the inner door panel assembly inside the water cutter mounting plate along the door thickness direction, it provides operating space for fastening components, facilitating assembly and maintenance. The inner and outer water cutters work together to form a protective barrier against water on the outside and a seal on the inside, effectively preventing rainwater infiltration and noise transmission, thus improving the vehicle's sealing performance.

[0020] Optionally, the door inner panel assembly is provided with an installation channel; the installation channel passes through the door inner panel assembly and is opposite to the first through hole, and the installation channel is used to install the fastening component.

[0021] The mounting channel of the door inner panel assembly runs through the entire door and aligns with the first through hole, providing a direct access path for fastening components from the inside of the door to the assembly position. This avoids insufficient assembly space caused by the door inner panel assembly obstructing the view, and is particularly convenient for tool operations such as bolt tightening, improving assembly efficiency. The mounting channel is coaxially aligned with the first through hole, guiding the fastening components to the target hole position, reducing assembly deviations and ensuring connection stability. At the same time, the through-type channel does not increase the complexity of the door inner panel, reserving space for later disassembly and maintenance, balancing convenience and maintainability.

[0022] On the other hand, embodiments of this application provide a vehicle that includes the door water-cutting mounting structure described in any of the above claims.

[0023] On the one hand, the flexible assembly of the external water-cutting device and the water-cutting mounting plate can significantly improve the waterproof and dustproof performance of vehicle doors, reducing rainwater seepage into the passenger compartment or dust accumulation in door gaps, while also reducing wind noise during vehicle operation and improving ride comfort. On the other hand, this door water-cutting mounting structure does not rely on special door edging processes and is compatible with different door types, such as framed and frameless doors, making it universally applicable across different vehicle configurations and reducing component development costs and production complexity caused by model differences.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. Based on the embodiments of the present utility model, any product that is the same as or similar to the present utility model, derived by anyone under the guidance of the present utility model or by combining the features of the present utility model with other related technologies, falls within the protection scope of the present utility model. Furthermore, all other embodiments obtained by those skilled in the art without inventive effort are within the protection scope of the present utility model.

[0028] Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of this utility model specification.

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] On the one hand, such as Figures 1 to 3 as well as Figure 9 and Figure 11As shown, this application embodiment provides a door water-cutting mounting structure, including: a door sheet metal assembly 100 and an outer water-cutting device 200. The door sheet metal assembly 100 includes a door outer panel assembly 110 and a water-cutting device mounting plate 120. The door outer panel assembly 110 has a insertion hole 111 and a first through hole 112, and the water-cutting device mounting plate 120 has a insertion tongue 121 and a second through hole 122. Along the height direction of the door, the insertion tongue 121 is inserted into the insertion hole 111, and the first through hole 112 and the second through hole 122 are fastened by a fastening assembly 300. The outer water-cutting device 200 is connected to the water-cutting device mounting plate 120.

[0031] Specifically, the door sheet metal assembly 100 includes a door outer panel assembly 110 and a water cutter mounting plate 120. The door outer panel assembly 110 has a pre-formed insertion hole 111 and a first through hole 112 at a preset position. One end of the water cutter mounting plate 120 is provided with an insertion tongue 121 that matches the shape and size of the insertion hole 111. The insertion tongue 121 can be integrally formed or welded with the main body of the water cutter mounting plate 120. This application embodiment does not limit it. A second through hole 122 is provided at the position corresponding to the first through hole 112.

[0032] During assembly, the tongue 121 of the water-cutting mounting plate 120 is inserted into the insertion hole 111 of the door outer panel assembly 110, forming an insertion fit along the height direction of the door. At this time, the second through hole 122 is coaxially aligned with the first through hole 112. The fastening assembly 300 passes through the second through hole 122 and the first through hole 112 in sequence, connecting the door outer panel assembly 110 and the water-cutting mounting plate 120, thereby achieving rigid fixation between the door outer panel assembly 110 and the water-cutting mounting plate 120 along the door. In the height direction, the end of the water-cutting mounting plate 120 away from the insertion tongue 121 is connected to the outer water-cutting 200. In some embodiments, the outer water-cutting 200 is provided with a slot adapted to the water-cutting mounting plate 120, and is connected to the screw on the water-cutting mounting plate 120 by engaging the slot, so that the outer water-cutting 200 is fixed on the water-cutting mounting plate 120, forming a complete door water-cutting mounting structure. The embodiments of this application do not limit the connection method between the outer water-cutting 200 and the water-cutting mounting plate 120. It is worth mentioning that the appendix... Figure 2 The diagram shows the door outer panel assembly 110 and the water jet mounting plate 120 secured by fasteners after the connector tongue 121 is inserted into the connector hole 111. (Attached) Figure 3 The diagram shows the door outer panel assembly 110 and the water-cutting mounting plate 120 secured by fasteners, but with the insertion tongue 121 not inserted into the insertion hole 111.

[0033] Understandably, the door water-cutting mounting structure connects the door outer panel assembly 110 to the water-cutting mounting plate 120 via an interlocking fit and fastening assembly 300. Compared to related technologies that weld the water-cutting mounting plate 120 to the door outer panel assembly 110, or install the outer water-cutting 200 on the door outer panel assembly 110 via a snap-fit ​​method, this structure eliminates the need for additional sheet metal brackets welded to the door sheet metal. This avoids limitations on the door edging process due to brackets, reduces reliance on special processes during door manufacturing, and helps lower production costs. Furthermore, this structure is not dependent on the specific construction of the door, whether it has a window frame or not; it can be fixed simply through the standardized assembly of the water-cutting mounting plate 120 and the door outer panel assembly 110. It is adaptable to different types of doors, including framed and frameless doors, improving the structure's universal adaptability. Meanwhile, the plug-in connection enables precise pre-positioning of the water cutter mounting plate 120 and the outer door panel assembly 110, ensuring quick alignment of the first through hole 112 and the second through hole 122, guaranteeing the connection stability of the fastening component 300 after installation, and thus ensuring the precise installation position of the outer water cutter 200.

[0034] Example 1 In some embodiments, such as Figures 2 to 6 As shown, the aforementioned door outer panel assembly 110 includes a waistline reinforcing plate 113 and a door outer panel 114; the door outer panel 114 is connected to the waistline reinforcing plate 113, and a connector hole 111 and a first through hole 112 are formed on the waistline reinforcing plate 113.

[0035] Specifically, the door outer panel assembly 110 consists of a door outer panel 114 and a waistline reinforcing plate 113. The door outer panel 114 can be formed by stamping cold-rolled steel sheet to form an arc-shaped appearance surface on the outer side of the door. This application embodiment does not limit its specific forming method and material. The waistline reinforcing plate 113 is a plate-shaped structure adapted to the inner contour of the door outer panel 114. The waistline reinforcing plate can be a steel plate, and this application embodiment does not limit it. Meanwhile, at the preset position of the waistline reinforcing plate 113, the insertion hole 111 and the first through hole 112 can be processed by stamping. The insertion hole 111 can be a rectangular hole. This application embodiment does not limit its specific shape and processing technology. Its size matches the insertion tongue 121 of the water cutter mounting plate 120. The first through hole 112 can be a circular hole. This application embodiment does not limit it. The hole diameter is adapted to the outer diameter of the fastening component 300. The insertion hole 111 and the first through hole 112 are arranged along the height direction of the door. The center distance between the two is consistent with the center distance between the insertion tongue 121 and the second through hole 122 on the water cutter mounting plate 120, so as to ensure the precise fit when the water cutter mounting plate 120 is assembled.

[0036] Understandably, placing the insertion hole 111 and the first through hole 112 on the waistline reinforcing plate 113 allows the structural strength of the waistline reinforcing plate 113 to ensure the overall structural stability of the door. Simultaneously, as a reinforcing component of the outer door panel 114, the waistline reinforcing plate 113 has a relatively fixed assembly position and high flatness, providing a precise machining benchmark for the insertion hole 111 and the first through hole 112, reducing hole position deviations, and improving the fitting accuracy with the water-cutting mounting plate 120. Furthermore, the outer door panel 114 only provides aesthetic and basic protective functions, while the waistline reinforcing plate 113 provides the connecting function for water-cutting assembly. This clear division of functions reduces the machining complexity of the outer door panel 114 and facilitates the separate replacement of the waistline reinforcing plate 113 during subsequent maintenance, reducing repair costs.

[0037] Optionally, by Figure 2 and Figure 3 As shown, the waistline reinforcement plate 113 includes a fitting section 1131 and a connecting section 1132; the fitting section 1131 is fitted to the outer door panel 114, and one end of the fitting section 1131 is connected to the edge of the outer door panel 114 to form a edging structure; the connecting section 1132 has a preset bending angle with the fitting section 1131; the insertion hole 111 and the first through hole 112 are opened in the connecting section 1132.

[0038] Specifically, the waistline reinforcement plate 113 includes a bonding section 1131 and a connecting section 1132. The bonding section 1131 is a flat plate structure that is bonded to the inner surface of the outer door panel 114. One end of the bonding section 1131 extends to the edge of the outer door panel 114. The edge of the outer door panel 114 has a folded section that folds inward, so that the bonding section 1131 and the edge of the outer door panel 114 together form a roll-pressed edge-wrapping structure, making the edges of the two tightly connected without sharp edges. The connecting section 1132 extends from the side of the bonding section 1131 away from the edge-wrapping structure, forming a preset bending angle with the bonding section 1131. The bending point is rounded. The connecting section 1132 is stamped with an insertion hole 111 and a first through hole 112, which are spaced apart along the height direction of the door, and the line connecting the centers of the holes is parallel to the extension direction of the connecting section 1132.

[0039] Understandably, the fitting section 1131 is fitted to the outer door panel 114 and connected by an edge-sealing structure. This not only enhances the structural strength of the door edge but also seals the connection gap between the outer door panel 114 and the waistline reinforcement plate 113, improving the door's waterproof and dustproof performance. The connecting section 1132 forms a preset bending angle with the fitting section 1131, allowing the connecting section 1132 to shift inward relative to the outer door panel 114, providing an independent assembly space for the water-cutting mounting plate 120 and avoiding interference with other structures of the outer door panel 114. The insertion hole 111 and the first through hole 112 are formed on the connecting section 1132. Utilizing the clearance space created by the bending, the assembly position of the water-cutting mounting plate 120 can better match the sealing requirements of the outer water-cutting 200. At the same time, the independent plate surface of the connecting section 1132 can ensure the accuracy of the opening and improve the stability of the fit with the water-cutting mounting plate 120.

[0040] Optionally, such as Figures 2 to 4 As shown, the water-cutting mounting plate 120 includes a mounting section 123, an opening section 124, and a plug-in section 125. Along the height direction of the door, one end of the mounting section 123 is connected to the outer water-cutting 200, and the other end is connected to the opening section 124. The other end of the opening section 124 is connected to the plug-in section 125, and the other end of the plug-in section 125 is provided with a plug-in tongue 121. A second through hole 122 is provided on the opening section 124. The opening section 124 and the mounting section 123 have a preset bending angle, and the opening section 124 fits against the connecting section 1132.

[0041] Specifically, the water-cutting mounting plate 120 can be a one-piece metal plate, including a mounting section 123, an opening section 124, and a plug-in section 125. Along the height direction of the door, the mounting section 123 can be a long flat plate, and one end of it can be provided with a slot adapted to the outer water-cutting 200. The outer water-cutting 200 can be fixed to the mounting section 123 by snapping it in the slot. This embodiment does not limit the connection method between it and the outer water-cutting 200. The other end of the mounting section 123 is connected to one end of the opening section 124, and there is a preset bending angle between them. This bending angle can be formed by stamping. This embodiment does not limit it. The bending point can be rounded to avoid stress concentration. The opening section 124 is a flat plate structure, and its plate surface is at least partially attached to the connecting section 1132 of the waistline reinforcing plate 113. A second through hole 122 is provided on the opening section 124 at the position corresponding to the first through hole 112 of the connecting section 1132. The other end of the opening section 124 is connected to one end of the plug section 125. The plug section 125 extends along the height of the door, and its other end is provided with a plug tongue 121 that matches the plug hole 111 of the waistline reinforcement plate 113. The thickness of the plug tongue 121 is the same as the width of the plug hole 111 to ensure that there is no looseness after insertion.

[0042] Understandably, the segmented structure of mounting section 123, perforation section 124, and plug-in section 125 can be designed according to the assembly requirements of the outer water cutter 200 and the mating requirements of the waistline reinforcement plate 113, improving the overall structural adaptability. The preset bending angles of mounting section 123 and perforation section 124 allow the outer water cutter 200 on mounting section 123 to conform to the outer contour of the door, ensuring a sealing and water-blocking effect while avoiding interference between the outer water cutter 200 and other door components. The fit between perforation section 124 and waistline reinforcement plate 113 connecting section 1132 increases the contact area between the two, improves connection stability, and facilitates fixation via fastening component 300. The plug-in section 125 ensures the mating of plug tongue 121 with waistline reinforcement plate 113 plug hole 111, achieving pre-positioning of water cutter mounting plate 120 and facilitating subsequent fastening assembly.

[0043] Optionally, such as Figure 4 As shown, the end of the plug section 125 connected to the opening section 124 has a connecting part 1251; the connecting part 1251 is an arc-shaped groove formed by recessing along the thickness direction of the door, one end of the connecting part 1251 is connected to the opening section 124, and the other end of the connecting part 1251 is connected to the plug tongue 121.

[0044] Specifically, the end where the plug-in section 125 and the opening section 124 connect has a connecting portion 1251. The connecting portion 1251 is provided at the connection between the plug-in section 125 and the opening section 124 of the water-cutting mounting plate 120. The connecting portion 1251 is an arc-shaped groove formed by recessing along the thickness direction of the door. The groove wall of the arc-shaped groove is smoothly transitioned without sharp corners. One end of the connecting portion 1251 is seamlessly connected to one end of the opening section 124 through an arc surface, and the other end is connected to one end of the plug-in section 125, so that the entire connecting portion 1251, opening section 124, and plug-in section 125 form a continuous bent transition structure, avoiding the occurrence of sharp corners with stress concentration.

[0045] Understandably, the connecting part 1251 is designed as an arc-shaped groove. This recessed structure provides buffer space in the thickness direction of the door, preventing rigid compression at the connection point between the plug section 125 and the opening section 124 due to slight door deformation or assembly errors, thus reducing the risk of breakage. The smooth transition of the arc-shaped groove disperses the force on the plug section 125, improving the overall structural strength of the water-cutting mounting plate 120. Simultaneously, the recessed shape of the arc-shaped groove reduces interference between this part and other door components. Especially in framed doors, it better accommodates the gap between the window frame and the door sheet metal, ensuring the fit between the plug tongue 121 and the plug hole 111 of the waistline reinforcement plate 113, indirectly improving the assembly stability of the outer water-cutting 200.

[0046] Example 2 Based on Example 1, such as Figures 2 to 3As shown, along the height direction of the door, the height of the outer water cut 200 does not exceed the height of the outer door panel 114.

[0047] Specifically, along the height direction of the car door, the height of the outer door panel 114 covers the lower edge of the window. After the outer water cutter 200 is fixed to the water cutter mounting plate 120 through the slot, its top end does not exceed the height boundary of the outer door panel 114 at the lower edge of the window, and the outer surface of the outer water cutter 200 is flush with the outer surface of the outer door panel 114. When viewed from the outside of the car door, the outer water cutter 200 is completely within the visual range covered by the height of the outer door panel 114, with no obvious protrusions or exposed parts, thus forming a hidden assembly form.

[0048] Understandably, limiting the height of the outer water cutter 200 along the height direction of the door to not exceed that of the outer door panel 114 serves two purposes. First, since the outer water cutter 200 does not exceed the height of the outer door panel 114, it can be naturally concealed by the outline of the outer door panel 114, creating a clean and unified appearance on the outside of the door, which meets the aesthetic requirements of the concealed design. Second, the matching height of the outer water cutter 200 with the outer door panel 114 allows it to connect with the door's sealing structure, ensuring both water and dust protection functions without structural redundancy caused by the exposed outer water cutter 200. It also reduces direct contact between the outer water cutter 200 and airflow during vehicle operation, thus reducing wind noise.

[0049] Example 3 Based on the above embodiment one, as follows Figure 4 and Figure 12 As shown, the fastening assembly 300 includes a nut 310 and a bolt 320; the nut 310 is fixed at the first through hole 112, and the bolt 320 passes through the second through hole 122 and the first through hole 112 and is connected to the nut 310.

[0050] Specifically, the fastening assembly 300 consists of a nut 310 and a bolt 320. The nut 310 can be fixed by welding to the first through hole 112 of the waistline reinforcing plate 113 connecting section 1132. This application embodiment does not limit the specific fixing method. The threaded hole of the nut 310 is coaxially aligned with the first through hole 112. The bolt 320 is a threaded bolt 320 adapted to the nut 310. Its length is longer than the sum of the thickness of the opening section 124 of the water-cutting mounting plate 120 and the thickness of the waistline reinforcing plate 113 connecting section 1132. During assembly, the bolt 320 passes through the second through hole 122 from the outside of the opening section 124 of the water-cutting mounting plate 120, passes through the opening section 124 and the first through hole 112 of the waistline reinforcing plate 113 connecting section 1132 in sequence, and is threadedly connected to the preset nut 310. It is tightened until the head of the bolt 320 is in contact with the surface of the opening section 124, so as to achieve rigid fixation of the two. It is worth mentioning that the nut 310 shown in the attached figure is a schematic diagram of the nut 310 being pressed along the thickness direction of the door after the bolt 320 is welded to the through hole. In the actual assembly process, the nut 310 can be set on the side of the waistline reinforcing plate 113 close to the inner water cutter 400 or on the side of the waistline reinforcing plate 113 away from the inner water cutter 400 along the thickness direction of the door. This application embodiment does not limit it.

[0051] Understandably, using a combination of nut 310 and bolt 320 as the fastening assembly 300, with nut 310 pre-fixed at the first through hole 112, simplifies the assembly process, eliminating the need to simultaneously align nut 310 and through hole in a confined space, thus improving assembly efficiency. Bolt 320 passes through the second through hole 122 and the first through hole 112 and connects to nut 310, forming an axial fastening force along the thickness direction of the door, ensuring a tight fit between the water-cutting mounting plate 120 and the waistline reinforcement plate 113 connecting section 1132, preventing gaps caused by vibration during vehicle operation. Simultaneously, the removability of the threaded connection facilitates the disassembly and assembly of the water-cutting mounting plate 120 during subsequent maintenance.

[0052] Example 4 Based on the above embodiment 1, the fastening assembly 300 is composed of an expansion sleeve and a bolt. The outer diameter of the expansion sleeve is adapted to the first through hole 112 and the second through hole 122. An axial opening groove is provided on the side wall of one end of the sleeve to form an elastically contractible expansion section. The diameter of the inner bolt is slightly smaller than the inner diameter of the expansion sleeve. During assembly, the expansion sleeve is first inserted into the second through hole 122 from one side of the opening section 124 of the water cutter mounting plate 120, and then through the first through hole 112 of the waistline reinforcing plate 113 connecting section 1132, so that the expansion section of the expansion sleeve extends out of the outside of the first through hole 112. Then, the inner bolt is screwed in from the end of the expansion sleeve away from the expansion section. When the conical expansion head of the inner bolt enters the expansion section of the expansion sleeve, it squeezes the side wall of the sleeve to open along the opening groove. The expanded sleeve tightly abuts against the hole wall of the first through hole 112 and the second through hole 122. At the same time, the head of the inner bolt presses against the surface of the opening section 124 of the water cutter mounting plate 120, thereby fixing the water cutter mounting plate 120 to the waistline reinforcing plate 113. Using expansion bolt 320 components as fastening components 300 eliminates the need for pre-fixing nuts 310 at the first through hole 112, saving the welding or pre-installation process of nuts 310 and simplifying the assembly process. This is especially suitable for scenarios where the inner space of the waistline reinforcement plate 113 is narrow and it is inconvenient to pre-fix nuts 310. Example 5 Based on the above embodiment one, as follows Figure 2 , Figure 3 and Figure 10 As shown, the door sheet metal assembly 100 also includes a door inner panel assembly 130, and the door water cutter mounting structure also includes an inner water cutter 400; along the thickness direction of the door, the door inner panel assembly 130 is disposed on the side of the water cutter mounting plate 120 away from the door outer panel assembly 110, and the inner water cutter 400 is connected to the door inner panel assembly 130.

[0053] Specifically, in addition to the outer door panel assembly 110 and the water-cutting mounting plate 120, the door sheet metal assembly 100 also includes an inner door panel assembly 130. The inner door panel assembly 130 can be a metal frame structure, located along the thickness direction of the door, on the side of the water-cutting mounting plate 120 away from the outer door panel assembly 110. The inner water-cutting 400 of the door water-cutting mounting structure can be provided with a barbed buckle on one side. An installation groove adapted to the buckle can be formed on the inner edge of the inner door panel assembly 130. The inner water-cutting 400 is engaged with the installation groove by the barbed buckle, thus fixing it to the inner door panel assembly 130. This application embodiment does not limit the specific connection method between the inner water-cutting 400 and the inner door panel assembly 130. After the inner water cutter 400 and the outer water cutter 200 are assembled in place, they correspond to the inner and outer sides of the door glass respectively along the thickness direction of the door. The two are symmetrically distributed to clamp the door glass, and the sealing contact of the clamping surfaces improves the waterproof and dustproof effect.

[0054] Understandably, the addition of the inner door panel assembly 130 to the door sheet metal assembly 100 allows it to work with the outer door panel assembly 110 to form a complete door frame, enhancing the overall structural strength of the door and providing a stable mounting base for the inner water cutter 400. The inner water cutter 400, connected to the inner door panel assembly 130, forms an inner door seal and can work with the outer water cutter 200 on the outer door panel assembly 110 side to effectively prevent rainwater from seeping into the vehicle interior through door gaps, while also reducing external noise entering the vehicle through these gaps.

[0055] Optionally, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the inner door panel assembly 130 is provided with an installation channel 131; the installation channel 131 passes through the inner door panel assembly 130 and is opposite to the first through hole 112, and the installation channel 131 is used to install the fastening component 300.

[0056] Specifically, the inner door panel assembly 130 is provided with an installation channel 131 that runs through the inner door panel assembly 130, corresponding to the assembly area of ​​the opening section 124 of the water-cutting mounting plate 120 and the connecting section 1132 of the waistline reinforcing plate 113. This installation channel 131 can be formed by stamping. In some embodiments, the installation channel 131 is a cylindrical channel with a diameter larger than the outer diameter of the fastening assembly 300, and the axis of the installation channel 131 coincides with the axis of the first through hole 112 on the waistline reinforcing plate 113, ensuring that the installation channel 131, the first through hole 112, and the second through hole 122 are coaxially aligned along the thickness direction of the door. In other embodiments, the installation channel 131 is a recessed structure along the height direction of the door, moving away from the inner water-cutting 400. The position of this recessed structure is opposite to that of the first through hole 112 and the second through hole 122. The embodiments of this application do not limit the specific structure of the installation channel 131. During assembly, the operator can insert the fastening component 300 through the installation channel 131 from the inside of the door, and then pass it through the second through hole 122 and the first through hole 112 in sequence to fasten the waistline reinforcement plate 113 and the water cutter mounting plate 120. The fastening operation can be completed without disassembling the inner door panel assembly 130.

[0057] On the other hand, this application also provides a vehicle that includes the door water-cutting mounting structure described in any of the above claims.

[0058] Equipping a vehicle with any of the aforementioned door water-cutting mounting structures offers several advantages. First, the flexible assembly of the outer water-cutting blade 200 and the water-cutting mounting plate 120 significantly enhances the waterproof and dustproof performance of the vehicle doors, reducing rainwater infiltration into the passenger compartment and dust accumulation in door gaps. It also reduces wind noise during vehicle operation, improving ride comfort. Second, this door water-cutting mounting structure eliminates the need for special door edging processes, making it compatible with various door types, including framed and frameless doors. This facilitates universal compatibility across different vehicle configurations, reducing component development costs and production complexity associated with model variations.
