Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to an internal opening structure for a car door. Background Technology

[0002] Against the backdrop of the continuous development of the automotive industry, the design of car doors, as a core component of the vehicle, not only affects the aesthetics of the vehicle's appearance but also directly impacts the user experience and the utilization of interior space. The rationality of the layout of the internal structure of the car door is a key factor in determining functional implementation and enhancing the user experience.

[0003] Currently, most existing car door opening mechanisms separate the inward-opening handle from the window lift button. This traditional design has significant drawbacks in practical applications: because the two functional components are independently located, they occupy different areas of the door trim panel, resulting in fragmented interior space. This is especially problematic in compact vehicles or designs with high interior space requirements, as this separate arrangement severely restricts the spatial planning of the door trim panel. This not only affects the rational layout of other functional components such as storage compartments and speakers but may also lead to a lack of fluidity in the overall interior design, thus reducing the efficiency and aesthetics of the interior space. Utility Model Content

[0004] The present invention aims to provide an internal opening structure for a car door, so as to achieve the integrated installation of an internal opening handle and a window lifting and opening button.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an internal opening structure for a car door, comprising a bottom shell panel and an inner sheet metal panel of the car door, wherein the bottom shell panel and the inner sheet metal panel of the car door are detachably connected, and the bottom shell panel is provided with a first mounting groove and a second mounting groove, wherein an inward opening handle is rotatably installed in the first mounting groove, and a window lifting and opening button is installed in the second mounting groove.

[0006] The beneficial effects of this solution are as follows: Compared with the existing technology where the inward-opening handle and the window lift button are arranged separately, this technical solution integrates the two functional components onto the same mounting interface through the integrated design of mounting slots one and two on the bottom panel. This effectively reduces the space occupied by the traditional independent arrangement and significantly improves the space utilization rate of the door interior panel. This integrated installation method completely solves the problem of fragmented space division, freeing up additional space for other components and significantly optimizing the rationality of the internal functional layout of the door.

[0007] Meanwhile, the integrated bottom panel design makes the interior design more cohesive, avoiding the visual fragmentation caused by the traditional scattered layout, and improving the smoothness of the interior lines. This achieves a dual improvement in the efficiency and aesthetics of interior space utilization, which is especially suitable for the space optimization needs of compact models.

[0008] Furthermore, this technical solution integrates the inward-opening handle and the window lift button onto the bottom panel, placing them in the optimal operating area for the human body, greatly improving ease of use. This integrated arrangement reduces the number of parts, saves development costs, and shortens the development cycle. Assembly is also more convenient, saving assembly time and improving production efficiency.

[0009] Furthermore, it also includes a locking component. The bottom of the first mounting slot has a through hole, and a connecting seat is fixedly connected to the side of the bottom panel away from the first mounting slot. The connecting seat is a cylindrical structure with one end open and the other end closed. Its open end is connected to the through hole, and its closed end has a first mounting hole. A second mounting hole is provided on the inner sheet metal of the door. The diameter of the through hole is larger than the size of the locking component. The bottom panel is installed on the inner sheet metal of the door through the locking component.

[0010] The beneficial effects of this design are as follows: During assembly, the locking component extends into the connecting seat through the through hole, with one end passing through the No. 1 mounting hole on the closed end of the connecting seat, thus fixing the bottom panel to the inner sheet metal of the door. Because the diameter of the through hole is larger than the outer diameter of the locking component, the head of the locking component can be completely recessed into the connecting seat, forming a recessed installation structure. This design avoids the locking component protruding from the surface of the bottom panel, preventing interference between components and affecting the operation of the inward-opening handle, while also maintaining the flatness of the interior surface.

[0011] In addition, this technical solution can connect the bottom panel to the inner sheet metal of the door with a single locking component, which reduces the number of fasteners used and significantly simplifies the installation process compared to the traditional multi-point fixing method.

[0012] Furthermore, several ribs are fixedly connected to the circumference of the connecting seat, and the side of the ribs near the bottom shell panel is fixedly connected to the bottom shell panel.

[0013] The beneficial effects of this solution are as follows: In this technical solution, the ribs arranged circumferentially on the connecting seat are fixedly connected to the bottom shell panel. The structural rigidity of the connecting seat is enhanced by the triangular support principle. At the same time, the surface contact fixation between the ribs and the bottom shell panel improves the assembly strength between the connecting seat and the bottom shell panel, ensuring the reliability of the integrated structure in long-term use.

[0014] Furthermore, a positioning rod is fixedly connected to the side of the bottom panel away from the first mounting slot, the side of the positioning rod is provided with a positioning groove, and a positioning hole is provided on the inner sheet metal of the door.

[0015] The beneficial effects of this solution are as follows: the positioning rod on the bottom panel engages with the positioning hole on the inner sheet metal of the door. During installation, the positioning rod passes through the positioning hole, and the positioning groove engages with the inner sheet metal of the door, achieving pre-positioning of the bottom panel and the inner sheet metal of the door. This pre-positioning structure can prevent misalignment during the installation of locking components, reduce adjustment steps to improve assembly efficiency, and at the same time, the engagement between the positioning groove and the sheet metal can suppress displacement under vibration conditions, enhancing connection reliability.

[0016] Furthermore, the inward-opening handle has a pull cable mounting groove, in which a door lock pull cable is installed, and at the other end of the door lock pull cable is a door lock.

[0017] The beneficial effects of this solution are as follows: Due to the setting of the cable mounting groove, this technical solution facilitates the installation of the door lock cable, while ensuring that the door lock cable maintains a stable transmission trajectory during the opening stroke, thereby improving the reliability and consistency of the door opening operation.

[0018] Furthermore, the inward-opening handle is L-shaped.

[0019] The beneficial effects of this solution are as follows: The inward-opening handle adopts an L-shaped structure design, which optimizes the length of the operating lever arm through the right-angle turn, making the force application angle when the handle is turned more ergonomic and improving the convenience for users to open the car door.

[0028] Example

[0029] like Figure 1 The diagram shows an interior door opening structure, including a bottom panel 1, an inner door sheet metal 2, and a locking component.

[0030] like Figure 2-3 As shown, a mounting groove 3 is formed on the left side of the front side of the bottom panel 1, and an inward-opening handle 4 is rotatably mounted in the mounting groove 3. Specifically, the inward-opening handle is L-shaped, and a pivot 5 is provided on the bottom panel 1. The inward-opening handle 4 is rotatably mounted on the pivot 5, and an elastic element 6 is sleeved on the pivot 5. One end of the elastic element 6 abuts against the bottom panel 1, and the other end abuts against the inward-opening handle 4, which is used to reset the inward-opening handle 4 from the unlocked position to the initial state. In this embodiment, the elastic element 6 is a spring.

[0031] like Figure 1 and Figure 4 As shown, the inward-opening handle has a cable mounting groove 7, in which a door lock cable 8 is installed. The other end of the door lock cable 8 is fitted with a door lock. When the occupant lifts the inward-opening handle 4, it rotates around the pivot 5, causing the door lock cable 8 to move. The distance the cable mounting groove 7 moves between the return state and the maximum open state is the opening stroke. In this embodiment, the door lock cable 8 and the door lock cooperate to open the door, which is existing technology and will not be described in detail here.

[0032] like Figure 2-3 As shown, a second mounting slot 9 is provided on the right side of the front side of the bottom panel 1, and a glass lifting and opening button 10 is installed in the second mounting slot 9.

[0033] like Figure 3 and Figure 5-6As shown, a through hole 11 is provided at the bottom of the first mounting slot 3. A connecting seat 12 is welded to the rear side of the bottom panel 1. The connecting seat 12 is a cylindrical structure with one end open and the other end closed. Its open end communicates with the through hole 11, and the closed end has a first mounting hole 13. A second mounting hole 14 is provided on the inner sheet metal 2 of the door. The diameter of the through hole 11 is larger than the size of the locking component. During assembly, the locking component passes through the through hole 11, the connecting seat 12, the first mounting hole 13, and the second mounting hole 14 to fix the connecting seat 12 to the inner sheet metal 2 of the door. Because the diameter of the through hole 11 is larger than the size of the locking component, the head of the locking screw can be recessed into the connecting seat 12, forming a recessed installation, avoiding protrusion from the panel surface that would affect operation or aesthetics. Three ribs 15 are welded to the circumference of the connecting seat 12, and the side of each rib 15 closest to the bottom panel 1 is welded to the bottom panel 1. The structural rigidity of the connecting seat 12 is enhanced by the triangular support principle.

[0034] like Figure 5 and Figure 6 As shown, two positioning rods 16 are welded to the rear side of the bottom panel 1. Each positioning rod 16 has a positioning groove 17 on its left side. The inner sheet metal 2 of the door has two corresponding positioning holes 18.

[0035] The specific implementation process is as follows:

[0036] During installation, first, the positioning rod 16 is passed through the positioning hole 18 of the inner sheet metal 2 of the door, so that the positioning groove 17 is engaged with the inner sheet metal 2 of the door, thereby achieving the pre-positioning of the bottom panel 1; then, the locking screw is passed through the through hole 11 and inserted into the connecting seat 12, and the bottom panel 1 is fixed through the mounting hole. This pre-positioning structure can prevent the locking parts from shifting during installation, improve assembly accuracy and efficiency, and at the same time, the positioning groove 17 engagement structure can suppress displacement under vibration conditions, enhancing connection reliability.
