Description

Technical Field

[0001] This application belongs to the field of vehicle door technology, and more specifically, relates to a door lock cable through hole assembly and a vehicle. Background Technology

[0002] In the design of the automotive door lock cable through-hole assembly, the door lock, door lock cable, and inner door handle constitute the inward opening system of the door. Since the door lock and inner door handle are located on the inner and outer sides of the inner panel sheet metal of the door, the door lock cable needs to pass through the sheet metal of the inner panel of the door.

[0003] In the existing technology, a large process clearance hole is designed on the sheet metal of the inner door panel. A waterproof membrane needs to be bonded to the clearance hole for sealing and waterproofing. At the same time, a through hole is often installed on the inner door panel near the clearance hole. The door lock cable is threaded through the through hole. However, the water and wind protection effect of the traditional through hole structure is poor. During the vehicle's operation, airflow can flow into the cabin through the notch where the through hole is installed, generating wind noise and affecting the comfort of the passengers. Utility Model Content

[0004] The purpose of this application is to provide a door lock cable through-hole assembly and a vehicle, aiming to solve the technical problems of poor waterproof and windproof performance of the through-hole structure of the door lock cable in existing door lock cable through-hole assemblies, which easily generates noise during driving and affects the comfort of the vehicle.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a door lock cable through-hole assembly is provided, comprising: The inner panel of the car door has a clearance hole and a mounting hole that are arranged through the inside and outside, and the mounting hole is connected to the clearance hole; A through-hole is fitted into the mounting hole; the through-hole has a wire-passing hole suitable for the door lock cable to pass through; the through-hole includes a first wing and a second wing, the first wing abutting against the inner side of the inner door panel, and the second wing abutting against the outer side of the inner door panel; and the wire-passing hole is provided through the first wing and the second wing; and A waterproof membrane is provided, covering the clearance hole and positioned on the inside of the door inner panel; the waterproof membrane extends to the first wing. Both the second wing plate and the first wing plate extend to the outer edge of the mounting hole and cover the inner panel of the door.

[0006] Compared with the prior art, the solution shown in this application embodiment allows the door lock cable to be routed to the outside of the vehicle body through the through hole on the through-hole device; sealing the first fin and the second fin inside the mounting hole can achieve the sealing of the mounting hole; furthermore, the outer edges of the first fin and the second fin extend to the inner panel of the door to form a cover over the joint of the mounting hole, so as to further intercept airflow and water flow and prevent airflow and water flow from seeping into the interior of the vehicle body from the joint of the mounting hole; Furthermore, in this application, the first fin and the second fin are clamped to the inner and outer sides of the inner door panel. On the one hand, this enhances the connection strength between the through hole and the inner door panel; on the other hand, it provides protection on both the inner and outer sides of the inner door panel, thus achieving double protection for the mounting hole and enhancing the protection against airflow and water flow. Specifically, the second fin in the wet area on the outer side of the inner door panel mainly provides primary protection for the mounting hole, while the first fin covering the inner side of the inner door panel provides auxiliary protection against leakage at the mounting hole. In addition, the waterproof membrane covering the first fin increases the protective effect at the connection between the clearance hole and the mounting hole, enhancing the interception effect against water and airflow. The connection between the mounting hole and the clearance hole on the inner door panel allows the waterproof membrane to extend directly to the first fin, further enhancing the protective effect.

[0007] Therefore, the door lock cable through-hole assembly provided in this application can effectively improve waterproof and windproof performance, reduce noise generated during driving, and help improve passenger comfort and safety.

[0008] In conjunction with the first aspect, in one possible implementation, a connecting portion is provided between the first wing plate and the second wing plate, and a clamping groove is formed between the connecting portion, the first wing plate, and the second wing plate; wherein, the connecting portion is sealed within the mounting hole, and the inner panel of the door is clamped within the clamping groove.

[0009] By setting a connecting part, the mounting hole can be sealed, while the connection strength between the first fin and the second fin can be enhanced. A clamping groove is formed by the first fin, the second fin and the connecting part, so that the first fin and the second fin can clamp the inner panel of the door, preventing the hole punch from coming out of the mounting hole during driving and affecting the windproof and waterproof effect.

[0010] In some embodiments, both the first fin and the second fin extend away from the clearance hole and are wedge-shaped structures that gradually narrow along their respective extension directions; wherein, the mounting hole is a wedge-shaped hole adapted to the wedge-shaped structure; and the clamping groove is a wedge-shaped groove that gradually narrows away from the clearance hole.

[0011] By setting the first and second fins as wedge-shaped structures, the overall shape of the through-hole device can be made into a wedge shape that gradually narrows away from the avoidance hole, which can realize guidance and positioning during the installation process of the through-hole device, thus facilitating the installation of the through-hole device on the inner panel of the car door; setting the mounting hole as a wedge-shaped hole can adapt to the shape of the connection between the first and second fins to ensure the overall wedge shape of the through-hole device; at the same time, the clamping groove is set as a wedge-shaped groove that gradually narrows away from the avoidance hole, which can facilitate the clamping of the through-hole device on the inner panel of the car door and make it easy to conform to the overall shape of the through-hole device during installation.

[0012] For example, the inner wall of the mounting hole is provided with a protrusion, and the end of the connecting part is limited at the protrusion.

[0013] By setting the protrusion extending into the wedge-shaped hole, the end of the connecting part can be limited, thereby ensuring the clamping strength of the through-hole and preventing the through-hole from coming off the mounting hole.

[0014] In conjunction with the first aspect, in one possible implementation, the second fin has two central notches, which are symmetrically distributed on both sides of the second fin along a first direction, wherein the first direction refers to the direction in which the second fin extends away from the clearance hole.

[0015] By setting a central notch, it is convenient for operators to clamp the two sides of the second fin plate, thereby facilitating the application of force to the through-hole device and thus enabling its installation.

[0016] In some embodiments, the extended end of the second fin is provided with a first guide opening that is inclined away from the first fin; Each of the central openings is defined as having two side walls along the first direction as first side walls, and each of the first side walls is provided with a second guide opening, which is inclined away from the central opening.

[0017] The first guide port is located at the extension end of the second wing plate, which can guide and install the extension end of the second wing plate to the mounting hole of the inner door panel. Specifically, during installation, the position of the first guide port of the second wing plate can be installed first. Since the first guide port is provided, the extension end of the second wing plate can be installed quickly, and then the other parts of the second wing plate can be installed.

[0018] The second guide port is located on the first side wall, which can prevent the through-hole from interfering with the sheet metal edge at the mounting hole during assembly, making the installation process of the through-hole smoother and avoiding installation difficulties or damage caused by interference.

[0019] In conjunction with the first aspect, in one possible implementation, the first wing plate has a reinforcing portion protruding into the vehicle compartment on the side away from the inner panel of the door, and the wire hole extends through the reinforcing portion.

[0020] By adding a reinforcing section, the support strength of the wire hole area on the first fin can be enhanced, ensuring the installation and support stability of the wire hole device.

[0021] In conjunction with the first aspect, in one possible implementation, the second fin has a cap-shaped portion protruding outward from the carriage; the axis of the wire-passing hole is inclined to the surface of the first fin, and the wire-passing hole passes through the cap-shaped portion from the first fin.

[0022] By setting the cap-shaped part, the support and installation strength of the second fin at the wire hole can be enhanced, and the door lock cable can be guided. The axis of the wire hole is inclined to the surface of the first fin, which can increase the extension length of the door lock cable in the through hole. At the same time, it increases the difficulty of external water and air flow passing through the wire hole, thus improving the windproof and waterproof effect.

[0023] In some embodiments, a reinforcing plate protruding outward from the carriage is provided between the cap-shaped portion and the second wing plate.

[0024] By adding a reinforcing plate, the support strength of the cap-shaped part is enhanced, thereby increasing the support stability of the door lock cable when it passes through the through hole.

[0025] Secondly, embodiments of this application also provide a vehicle including the aforementioned door lock cable through-hole assembly.

[0026] The vehicle provided in this application embodiment includes the aforementioned door lock cable through hole assembly, and thus has all the beneficial effects of the aforementioned door lock cable through hole assembly. It can effectively improve the waterproof and windproof effect of the door lock cable through part, reduce the noise generated during driving, and help improve the comfort and safety of passengers.

Detailed Implementation

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down". The "inner" side of the vehicle refers to the side facing the inside of the passenger compartment, and the "outer" side refers to the side facing the outside of the passenger compartment.

[0034] It should be understood that the "first direction" in this application refers to the extension direction of the via 2, and the extension direction of the via 2 is the same as the extension direction of the first fin 21 and the second fin 22; specifically, the extension direction of the first fin 21 refers to the extension direction of the first fin 21 away from the clearance hole 11, and the extension direction of the second fin 22 refers to the extension direction of the second fin 22 away from the clearance hole 11; and the extension direction of the via 2 also refers to the extension direction of the via 2 away from the clearance hole 11; for ease of understanding, the appendix is ​​used in this application. Figure 3 The direction of the middle arrow A indicates the direction of extension, i.e., the first direction.

[0035] It should be noted that in the prior art, the existing door inner panel 1 has an avoidance hole 11, which is used to avoid other structural components of the door assembly, specifically the glass lifting assembly. A waterproof membrane 3 is provided on the side of the door inner panel 1 facing the inside of the passenger compartment. The waterproof membrane 3 is used to seal the avoidance hole 11, and the waterproof membrane 3 is fixed to the inner side of the door inner panel 1 to prevent external water from entering the passenger compartment.

[0036] In addition, the inner panel 1 of the door is provided with an installation hole 12 for the door lock cable 4 to pass through to the outside of the car body. The installation hole 12 is sealed by a through hole 2 or other sealing structure, and the door lock cable 4 is passed through it.

[0037] In traditional designs, the clearance hole 11 where the waterproof membrane 3 is installed and the mounting hole 12 through which the door lock cable 4 passes are usually separated from each other. That is, there is a sheet metal of the inner door panel 1 between the mounting hole 12 and the clearance hole 11, and the waterproof structures at the two locations are also independent of each other. Therefore, after the waterproof structure is installed, there will be potential for water and air leakage at the gaps where the waterproof membrane 3 meets the sheet metal of the door, as well as at the gaps where the through hole 2 meets the sheet metal of the door.

[0038] Please refer to the following: Figures 1 to 6The present application will now describe the door lock cable through hole assembly and the vehicle provided in this application. The door lock cable through-hole assembly includes a door inner panel 1, a through-hole device 2, and a waterproof membrane 3. The door inner panel 1 has an inner and outer through-hole 11 and a mounting hole 12, and the mounting hole 12 communicates with the through-hole 11. The through-hole device 2 is snapped into the mounting hole 12. The through-hole device 2 is provided with a through-hole 24 suitable for the door lock cable 4 to pass through. The through-hole device 2 includes a first wing 21 and a second wing 22. The first wing 21 abuts against the inner side of the door inner panel 1, and the second wing 22 abuts against the outer side of the door inner panel 1. The through-hole 24 is provided through the first wing 21 and the second wing 22. The waterproof membrane 3 covers the through-hole 11 and is located on the inner side of the door inner panel 1. The waterproof membrane 3 extends to the first wing 21. The second wing 22 and the first wing 21 both extend towards the outer edge of the mounting hole 12 and cover the door inner panel 1.

[0039] It should be understood that, compared to the traditional technology where the clearance hole 11 and the mounting hole 12 are set independently, the connection gap between the clearance hole 11 and the inner door panel 1, as well as the connection gap between the mounting hole and the inner door panel 1, are all relatively complete units, so the overall length of the sum of the aforementioned gaps is relatively long. In this application, the clearance hole 11 and the mounting hole 12 are interconnected. Therefore, the sum of the connection gap between the clearance hole 11 and the inner door panel 1, and the connection gap between the mounting hole 12 and the inner door panel 1, can be relatively reduced in overall length. Thus, the risk of air and water leakage at the gaps can be reduced to a certain extent.

[0040] The through-hole device 2 includes a first wing 21 and a second wing 22 that are clamped to the inner and outer sides of the inner door panel 1. Specifically, the first wing 21 is pressed against the inner side of the inner door panel 1 facing the inside of the vehicle compartment, and the second wing 22 is pressed against the outer side of the inner door panel 1 away from the inside of the vehicle compartment. In addition, since the first wing 21 and the second wing 22 are clamped to the inner door panel 1, the first wing 21 has a certain pressure against the inner side of the inner door panel 1, and the second wing 22 has a certain pressure against the outer side of the inner door panel 1.

[0041] Specifically, the first wing 21 is located in the dry area inside the inner panel 1 of the door and is in contact with the inner sheet metal surface of the inner panel 1. Its main function is to seal and prevent water and air from entering. The second wing 22 is located in the wet area outside the inner panel 1 of the door and has an interference of 0.06mm-0.15mm between it and the sheet metal surface of the inner panel 1. Preferably, the interference is 0.1mm. This is mainly used to increase the adhesion between the first wing 21 and the inner sheet metal of the inner panel 1 to ensure sealing. At the same time, it enhances the friction between the first wing 21 and the second wing 22 and the corresponding sheet metal of the inner panel 1, thereby preventing the through hole 2 from coming out of the mounting hole 12 of the inner panel 1.

[0042] It should be noted that the interference between two adjacent structural components referred to in this application refers to the connection between the two components by means of an interference fit, which is used to ensure the tightness of the connection between the two components.

[0043] It should be understood that when the first wing plate 21 and the second wing plate 22 are installed on the inner panel 1 of the door, due to the 0.1mm interference designed on the second wing plate 22, a certain amount of resistance can be formed between the inner side of the first wing plate 21 and the inner side of the inner panel 1 of the door, and between the second wing plate 22 and the outer side of the inner panel 1 of the door. Therefore, it can also be understood that the first wing plate 21 and the second wing plate 22 clamp the inner panel 1 of the door from the inside and outside, and form double protection on the inner and outer sides of the inner panel 1 of the door.

[0044] Optionally, the first fin 21 is a large fin, and the second fin 22 is a small fin. Since the first fin 21 has a larger surface area, it can be used to prevent leakage and fill gaps between the second fin 22 and the inner door panel 1, that is, to supplement and protect against small-scale airflow and water flow leakage between the second fin 22 and the inner door panel 1.

[0045] It should be understood that the size of the first fin plate 21 is larger than the size of the second fin plate 22. The large fin plate and small fin plate used in this application are "large" and "small" in a relative sense. That is to say, there is a difference in the surface size of the first fin plate 21 and the second fin plate 22, and the surface of the first fin plate 21 is larger than that of the second fin plate 22.

[0046] Furthermore, the surface area of ​​the second wing plate 22 is larger than the surface area of ​​the mounting hole 12, so that the second wing plate 22 extends to the outer edge of the mounting hole 12 and covers the inner panel 1 of the door to achieve the outer sealing of the mounting hole 12; while the surface area of ​​the first wing plate 21 is larger than the surface area of ​​the second wing plate 22, so that the surface area of ​​the first wing plate 21 is also larger than the surface area of ​​the mounting hole 12, so that the first wing plate 21 extends to the outer edge of the mounting hole 12 and covers the inner panel 1 of the door to achieve the inner sealing of the mounting hole 12.

[0047] Preferably, the through-hole device 2 is made of TPE material. TPE is a thermoplastic elastomer material with high strength, high resilience, and injection molding properties. It has a wide range of applications, is environmentally friendly, non-toxic, and safe, and has excellent colorability. Therefore, the through-hole device 2 made of TPE material has a better sealing effect.

[0048] Furthermore, the waterproof membrane 3 is adhered to the inner dry area of ​​the door inner panel 1 and extends to the first fin 21 of the through-hole 2. The door lock cable 4 is connected between the door lock and the inner handle through the cable hole 24 on the through-hole 2. The door lock cable through-hole assembly provided in this application not only meets the layout requirements of the door lock system, but also reduces the risk of airflow and water entering the passenger compartment through the mounting hole 12 and the clearance hole 11 during vehicle operation, thus reducing the risk of wind noise.

[0049] Optionally, the thickness of the first wing plate 21 is designed to be 3mm, and the thickness of the second wing plate 22 is 2mm, so as to ensure that sufficient sealing pressure is provided when clamping the inner panel 1 of the door, without adding unnecessary weight due to excessive thickness.

[0050] Optionally, the waterproof membrane 3 is made of rubber with high elasticity and good waterproof performance, and its thickness is 0.5mm. During installation, the waterproof membrane 3 is firmly attached to the inside of the door inner panel 1 and the first wing plate 21 with special adhesive to ensure a sealing effect.

[0051] Compared with the prior art, the door lock cable through-hole assembly provided in this application allows the door lock cable 4 to be led out of the vehicle body through the through-hole 24 on the through-hole device 2; by sealing the first fin 21 and the second fin 22 inside the mounting hole 12, the mounting hole 12 can be sealed; furthermore, the outer edges of the first fin 21 and the second fin 22 extend to the inner panel 1 of the door, forming a cover over the joint of the mounting hole 12, to further intercept airflow and water flow, preventing airflow and water flow from seeping into the interior of the vehicle body from the joint of the mounting hole 12; and, in this application, through The first fin 21 and the second fin 22 are clamped on the inner and outer sides of the inner door panel 1. On the one hand, they can enhance the connection strength between the through hole 2 and the inner door panel 1. On the other hand, they can provide protection on both the inner and outer sides of the inner door panel 1, thereby achieving double protection for the mounting hole 12 and enhancing the protection against airflow and water flow. Specifically, the second fin 22 is located in the wet area on the outer side of the inner door panel 1, mainly providing primary protection for the mounting hole 12. The first fin 21 covers the inner side of the inner door panel 1, providing auxiliary protection against leakage at the mounting hole 12.

[0052] In addition, the waterproof membrane 3 covering the first fin plate 21 can increase the protective effect at the connection between the avoidance hole 11 and the mounting hole 12, and enhance the interception effect of water flow and air flow. On the inner panel 1 of the door, the mounting hole 12 and the avoidance hole 11 are connected, which can facilitate the waterproof membrane 3 to extend directly to the first fin plate 21 to enhance the protective effect.

[0053] Therefore, the door lock cable through-hole assembly provided in this application can effectively improve waterproof and windproof performance, reduce noise generated during driving, and help improve passenger comfort and safety.

[0054] Please see Figure 5 In some possible embodiments, a connecting portion 23 is provided between the first wing plate 21 and the second wing plate 22, and a clamping groove is formed between the connecting portion 23, the first wing plate 21 and the second wing plate 22; wherein, the connecting portion 23 is sealed in the mounting hole 12, and the inner door panel 1 is clamped in the clamping groove.

[0055] By setting the connecting part 23, the mounting hole 12 can be blocked, and the connection strength between the first wing plate 21 and the second wing plate 22 can be enhanced. The clamping groove is formed by the first wing plate 21, the second wing plate 22 and the connecting part 23, so that the first wing plate 21 and the second wing plate 22 can clamp the inner panel 1 of the door, and prevent the through hole 2 from coming out of the mounting hole 12 during driving, which would affect the windproof and waterproof effect.

[0056] The structure of the connecting part 23 and the clamping groove enhances the connection stability between the through hole 2 and the inner door panel 1, further ensuring the sealing of the entire through hole assembly and preventing water and airflow from entering the cabin.

[0057] Specifically, a clamping groove is formed between the outer peripheral surface of the connecting part 23, the outer side of the first wing plate 21 facing the inner side of the door panel 1, and the inner side of the second wing plate 22 facing the inner side of the door panel 1. The clamping groove has a U-shaped cross section, and the U-shaped opening of the U-shaped clamping groove faces the inner side of the door panel 1.

[0058] Additionally, it should be noted that the clamping groove extends from the extension end of the first fin plate 21 away from the clearance hole 11 to both sides of the first fin plate 21, and extends to the junction of the clearance hole 11 and the mounting hole 12.

[0059] Optionally, the connecting part 23 is integrally formed with the first fin 21 and the second fin 22 to enhance the stability of the overall structure. The connecting part 23 has a width of 5mm and a height of 4mm, and its thickness can be reasonably set according to the thickness requirements of the inner door panel 1. This size design can ensure its sealing effect in the mounting hole 12 without having an excessive impact on the overall strength of the through hole 2.

[0060] Optionally, the connecting part 23 fits against the sheet metal edge of the mounting hole 12. Preferably, there is also interference between the connecting part 23 and the sheet metal edge of the mounting hole 12. Optionally, the interference between the connecting part 23 and the sheet metal edge of the mounting hole 12 is 0.1mm.

[0061] Please see Figure 4 or Figure 5 In some embodiments, the first fin plate 21 and the second fin plate 22 both extend away from the clearance hole 11 and both have a wedge-shaped structure that gradually narrows along their respective extension directions; wherein, the mounting hole 12 is a wedge-shaped hole adapted to the wedge-shaped structure; and the clamping groove is a wedge-shaped groove that gradually narrows away from the clearance hole 11.

[0062] By setting the first fin plate 21 and the second fin plate 22 as a wedge-shaped structure, the overall shape of the through hole 2 can be made into a wedge-shaped body that gradually narrows away from the avoidance hole 11, which can realize the guidance and positioning of the through hole 2 during the installation process, and thus facilitate the installation of the through hole 2 on the inner panel 1 of the car door.

[0063] The mounting hole 12 is set as a wedge-shaped hole, which can be adapted to the shape of the connecting part 23 between the first fin plate 21 and the second fin plate 22 to ensure the overall wedge shape of the through hole 2. The wedge-shaped hole of the mounting hole 12 is precisely matched with the wedge structure of the through hole 2. During installation, the worker only needs to gently push the through hole 2 along the wedge-shaped hole to complete the installation quickly and accurately.

[0064] Meanwhile, the clamping groove is set as a wedge-shaped groove that gradually narrows away from the clearance hole 11, which can facilitate the clamping of the inner door panel 1 by the through hole 2, and also makes it easy to conform to the overall shape of the through hole 2 during installation, which is conducive to improving the installation efficiency of the through hole 2.

[0065] In addition, since both the first wing plate 21 and the second wing plate 22 are wedge-shaped, the clamping groove is also set as a wedge-shaped structure, so that the connecting part 23 can be adapted to the wedge shape of the first wing plate 21 and the second wing plate 22, making it easier for the inner panel 1 of the door to be inserted into the corresponding part of the clamping groove.

[0066] Furthermore, the wedge-shaped tops of the first fin plate 21 and the second fin plate 22 are circular transition structures, that is, the extended ends of the first fin plate 21 and the second fin plate 22 are both circular transition surfaces, to facilitate installation.

[0067] In addition, the end of the connecting part 23 near the extension end of the first fin plate 21 is also a rounded transition structure, and the end of the connecting part 23 and the clearance hole 11 is designed with a rounded corner transition structure.

[0068] Please see Figure 3 For example, a protrusion 121 is provided on the inner wall of the mounting hole 12, and the end of the connecting part 23 is limited at the protrusion 121.

[0069] Specifically, the mounting hole 12 has a protrusion 121 extending into the wedge-shaped hole at one end near the clearance hole 11.

[0070] By setting the protrusion 121 extending into the wedge-shaped hole, the end of the connecting part 23 can be limited, thereby ensuring the clamping strength of the through hole 2 and preventing the through hole 2 from coming off the mounting hole 12.

[0071] It should be understood that the design of the protrusion 121 further improves the positioning accuracy and stability of the via 2 within the mounting hole 12, ensuring that the via 2 is securely installed and well-sealed.

[0072] Specifically, two protrusions 121 are provided, distributed on both sides of the via 2 extending away from the clearance hole 11; and a notch is left between the two protrusions 121 to connect the mounting hole 12 and the clearance hole 11. Compared with the structure where the mounting hole 12 and the clearance hole 11 are independent of each other by connecting the two protrusions 121, the presence of the notch makes it easier to apply force to install the via 2 into the mounting hole 12, thereby improving the installation efficiency of the via 2.

[0073] Preferably, the end of the connecting portion 23 near the clearance hole 11 has an arc-shaped structure, and the arc-shaped structure abuts against the two protrusions 121; furthermore, the arc-shaped structure and the protrusions 121 form an interference amount so that the through hole 2 is locked in the mounting hole 12; preferably, the arc-shaped structure of the connecting portion 23 and the clearance hole 11 for the interference amount between the protrusions 121 is 0.5mm.

[0074] Please see Figure 4 or Figure 5 In conjunction with the first aspect, in one possible implementation, the second fin plate 22 is provided with two central notches 221, which are symmetrically distributed on both sides of the second fin plate 22 along a first direction; wherein, the first direction refers to the extension direction of the second fin plate 22 away from the avoidance hole 11.

[0075] By setting a central notch 221, it is convenient for the operator to clamp the two sides of the second fin plate 22, thereby facilitating the operator to apply force to the through hole device 2 and thus realize the installation of the through hole device 2.

[0076] Specifically, two central notches 221 are symmetrically distributed on both sides of the second fin plate 22 along the first direction. The central notches 221 make it easy for personnel to pinch the opposite sides of the through hole device 2 with their fingers, which facilitates the installation operation and improves the installation efficiency.

[0077] In addition, the symmetrical arrangement of the central notch 221 can improve the uniformity and consistency of the force on the second fin plate 22, ensure the symmetry and accuracy of the installation of the through hole 2, and make the sealing consistency between the through hole 2 and the mounting hole 12 on both sides better.

[0078] Please see Figures 4 to 6 In some embodiments, the extended end of the second fin plate 22 is provided with a first guide opening 222 that is inclined away from the first fin plate 21; the two side walls of each central notch 221 along the first direction are defined as first side walls, and each first side wall is provided with a second guide opening 223, and the second guide openings 223 are all inclined away from the central notch 221.

[0079] The first guide port 222 and the second guide port 223 are provided to prevent the through-hole 2 from interfering with the sheet metal edge of the inner door panel 1 during assembly.

[0080] Specifically, the first guide port 222 is provided at the extension end of the second wing plate 22, which can realize the guidance and installation of the extension end of the second wing plate 22 to the mounting hole 12 of the inner panel 1 of the door. Specifically, during installation, the position of the first guide port 222 of the second wing plate 22 can be installed first. Here, since the first guide port 222 is provided, the extension end of the second wing plate 22 can be quickly installed, and then the other parts of the second wing plate 22 can be installed.

[0081] In addition, the second guide opening 223 is set on the first side wall. Since there is an interference between the second fin plate 22 and the sheet metal surface of the inner door panel 1, when the operator holds the through hole 2 by hand for installation, it is sometimes necessary to swing the through hole 2 in the direction of the inside and outside of the car body so that the through hole 2 can be smoothly installed in the mounting hole 12. During the swinging process, the edge of the fin plate 22 is prone to interfere with the sheet metal edge at the mounting hole 12. By setting the second guide opening 223 on the first side wall, the degree of interference can be reduced to a certain extent. Thus, while retaining the surface of the second fin plate 22, the interference part of the second fin plate 22 can be reduced as much as possible, thereby reducing the difficulty of installing the through hole 2 as much as possible.

[0082] The first guide port 222 and the second guide port 223 can prevent the through-hole device 2 from interfering with the sheet metal edge during assembly, making the installation process of the through-hole device 2 smoother and avoiding installation difficulties or damage caused by interference.

[0083] Please see Figure 5 In some possible embodiments, the first wing plate 21 has a reinforcing part 211 protruding into the carriage on the side away from the inner panel 1 of the door, and the wire hole 24 passes through the reinforcing part 211.

[0084] By setting the reinforcing part 211, the support strength of the wire hole 24 area on the first fin plate 21 can be enhanced, ensuring the installation and support stability of the through hole 2.

[0085] It should be understood that the reinforcing part 211 increases the strength of the first fin plate 21, enabling it to better withstand the tension generated when the door lock cable 4 passes through and the vibration during vehicle operation; at the same time, the cable hole 24 extends through the reinforcing part 211, thus further ensuring the stability and sealing of the door lock cable 4 when it passes through.

[0086] Please see Figure 5 In some possible embodiments, the second wing plate 22 is provided with a cap-shaped portion 224 protruding outward from the carriage; the axis of the wire hole 24 is inclined to the surface of the first wing plate 21, and the wire hole 24 passes through the cap-shaped portion 224 from the first wing plate 21.

[0087] By setting the cap-shaped part 224, on the one hand, the support and installation strength of the second wing plate 22 at the wire hole 24 can be enhanced, and on the other hand, the door lock pull cable 4 can be guided. The axis of the wire hole 24 is inclined to the plate surface of the first wing plate 21, which can increase the extension length of the door lock pull cable 4 in the through hole 2. At the same time, it increases the difficulty of external water flow and air flow passing through the wire hole 24, and improves the windproof and waterproof effect.

[0088] Specifically, the cap-shaped part 224 helps to further seal the part through which the door lock cable 4 passes, preventing airflow from entering the cabin. The inclined cable hole 24 axis design can better match the door lock cable 4, ensuring the sealing effect and the placement of the through hole 2 on the cable.

[0089] Preferably, the angle between the axis of the wire hole 24 and the surface of the first fin plate 21 is 30°. This inclined design allows the door lock pull cable 4 to better fit against the inner wall of the wire hole 24 when it passes through the wire hole 24, improving the sealing performance. It also makes it easier to ensure the placement of the through hole device 2 on the pull cable.

[0090] Please see Figure 4 In some embodiments, a reinforcing plate 225 protruding outward from the carriage is provided between the cap-shaped portion 224 and the second wing plate 22.

[0091] By setting a reinforcing plate 225, the support strength of the cap-shaped part 224 is enhanced, thereby increasing the support stability of the part of the door lock cable 4 that passes through the through hole 2.

[0092] Specifically, multiple reinforcing plates 225 can be provided, and the multiple reinforcing plates 225 are spaced apart around the axis of the wire hole 24.

[0093] Preferably, a set of reinforcing plates 225 are provided, and the extending direction of the reinforcing plates 225 is parallel to the extending direction of the through hole 2 away from the extension direction of the avoidance hole 11.

[0094] Furthermore, a certain amount of interference is left between the door lock cable 4 and the inner wall of the wire hole 24; optionally, the interference between the wire hole 24 and the door lock cable 4 is between 0.06mm and 1.5mm, preferably, the interference between the wire hole 24 and the door lock cable 4 is 0.1mm.

[0095] Optionally, the reinforcing plate 225, the cap-shaped part 224, and the second wing plate 22 are integrally formed, resulting in high connection strength.

[0096] Based on the same inventive concept, this application also provides a vehicle including the above-mentioned door lock cable through hole assembly.

[0097] It should be noted that during the production process, each structural component must be strictly inspected according to the design requirements to ensure that all indicators, such as the fitting accuracy between the through hole 2 and the mounting hole 12 on the inner panel of the door, and the adhesion quality of the waterproof membrane 3, meet the standards.

[0098] It's important to understand that by adopting the aforementioned door lock cable perforation assembly on the vehicle, the problem of wind noise generated by airflow entering the cabin through the three openings in the waterproof membrane during vehicle operation is significantly improved. Passengers inside the vehicle can experience a quieter and more comfortable driving environment at high speeds, enhancing the overall quality of the vehicle and the user experience.

[0099] Therefore, the vehicle provided in this application embodiment, since it includes the above-mentioned door lock cable through hole assembly, has all the beneficial effects of the above-mentioned door lock cable through hole assembly, which can effectively improve the waterproof and windproof effect of the part through which the door lock cable 4 passes, reduce the noise generated during driving, and help improve the comfort and safety of passengers.

[0100] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
