Technical Field
[0001] This utility model relates to the field of vehicle interior technology, and in particular to a position adjustment mechanism, a door assembly, and an automobile. Background Technology
[0002] During vehicle assembly, the matching requirements between the door trim panels and the dashboard are high, especially the matching quality between the front end of the door trim panel and the side end of the dashboard, which directly affects the overall interior appearance and assembly precision. Furthermore, because the entire matching process involves a long dimensional chain, even minor errors can affect the final product yield.
[0003] Traditional door trim panels are usually fixedly installed on the door sheet metal. This installation method is difficult to effectively compensate for assembly tolerances, which can easily lead to gaps exceeding tolerances between the door trim panel and its surrounding components. Utility Model Content
[0004] The purpose of this utility model is to provide a position adjustment mechanism, a door assembly, and an automobile. The position adjustment mechanism can adjust the position of the door trim panel relative to the door sheet metal, thereby compensating for the assembly tolerances of the door trim panel and its cooperating peripheral components.
[0005] To achieve the above objectives, this utility model proposes a position adjustment mechanism, including a mounting bracket and an adjusting component. The mounting bracket is used to fix and connect with the door trim panel. A part of the adjusting component passes through the mounting bracket and is pulsatorically connected to the mounting bracket. The other part of the adjusting component passes through the door sheet metal and can rotate relative to the door sheet metal. Rotating the adjusting component can drive the mounting bracket to move relative to the adjusting component.
[0006] Optionally, the mounting bracket includes a mounting plate and a side plate, wherein at least two opposite edges of the mounting plate are bent and extended to form the side plate, and the mounting plate and the side plate enclose a mounting space for accommodating the adjustment element.
[0007] Optionally, the adjusting component includes an adjusting rod with an active transmission part, and the mounting bracket has a driven transmission part that cooperates with the active transmission part. The active transmission part and the driven transmission part are connected in a transmission relationship to drive the mounting bracket to move relative to the adjusting component.
[0008] Optionally, the adjusting component also includes a driving part and a limiting part, which are respectively located at opposite ends of the adjusting rod. The driving part is used to drive the active transmission part to rotate under the action of the control force; the limiting part is used to abut against the door sheet metal to limit the relative position of the adjusting component and the mounting bracket along the axial direction of the adjusting rod.
[0009] Optionally, the limiting part includes a limiting flange and a positioning post, the positioning post being used to pass through the door sheet metal, and the limiting flange being used to abut against the door sheet metal.
[0010] Optionally, the positioning post is provided with a guide section, the diameter of which gradually decreases in the direction away from the limiting flange.
[0011] Optionally, the mounting plate of the mounting bracket is provided with mounting holes for the positioning pin to pass through, and the area of the mounting plate corresponding to the mounting hole is provided with at least two limiting flanges, which are located on opposite sides of the mounting hole and abut against the limiting flange of the adjusting member.
[0012] Optionally, the end of the side panel away from the mounting plate is bent and extended in a direction away from its corresponding side panel to form a fixing plate for fixed connection with the door trim panel. One of the fixing plate and the door trim panel is provided with a connecting post, and the other is provided with a connecting hole corresponding to the connecting post. The connecting post passes through the connecting hole and is fixedly connected to the part around the connecting hole.
[0013] This utility model also proposes a car door assembly, including a car door sheet metal, a car door trim panel, and the aforementioned position adjustment mechanism, wherein the car door trim panel is connected to the car door sheet metal via the position adjustment mechanism.
[0014] This utility model also proposes an automobile, including the aforementioned door assembly.
[0015] Compared with the prior art, the technical solution of this utility model has the following advantages: The position adjustment mechanism of this utility model connects the mounting bracket and the adjusting component to the door trim panel and the door sheet metal respectively. The adjusting component is connected to the mounting bracket through a transmission. Rotating the adjusting component can drive the mounting bracket to move relative to the adjusting component, thereby driving the door trim panel to move relative to the door sheet metal, thereby compensating for the assembly tolerance between the door trim panel and its surrounding components during the assembly process.

Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.
[0031] This utility model provides an automobile, including a door assembly. The door assembly includes a door sheet metal (not shown), a door trim panel 3, and a position adjustment mechanism. The door trim panel 3 is connected to the door sheet metal via the position adjustment mechanism. The position adjustment mechanism can adjust the relative position between the door trim panel 3 and the door sheet metal during the assembly process to compensate for the assembly tolerance between the door trim panel 3 and its surrounding components such as the dashboard, thereby improving the pass rate of matching between the front end of the door trim panel 3 and the side end of the dashboard.
[0032] Please see Figure 1 In some embodiments provided in this application, the position adjustment mechanism includes a mounting bracket 1 and an adjusting member 2. The mounting bracket 1 is fixedly connected to the door trim panel 3 by at least one of welding, fastener connection and snap-fit. A part of the adjusting member 2 is located inside the mounting bracket 1 and is pulsatorically connected to the mounting bracket 1. The other part of the adjusting member 2 passes through the door sheet metal and is able to rotate relative to the door sheet metal.
[0033] Please see Figure 1 and Figure 2The door trim panel 3 has an adjustment hole 32 in the area corresponding to the mounting bracket 1 for a screwdriver to pass through. A cover plate (not shown) is provided on the side of the door trim panel 3 closest to the passenger compartment for aesthetic purposes. The cover plate is fixed to the door trim panel 3 by snap-fitting, fastener connection, or other means. In use, the cover plate is opened, the screwdriver is inserted into the adjustment hole 32 and fitted onto the adjustment component 2, and rotating the adjustment component 2 drives the mounting bracket 1 to move relative to the adjustment component 2, thereby moving the door trim panel 3 relative to the door sheet metal.
[0034] Please see Figure 3 and Figure 4 In one embodiment, the mounting bracket 1 is generally rectangular or trapezoidal in shape. The mounting bracket 1 includes a mounting plate 11 and a side plate 12. Specifically, at least two opposite edges of the mounting plate 11 are bent and extended to form the side plate 12. The mounting plate 11 and the side plate 12 enclose a mounting space 14 for accommodating the adjustment member 2.
[0035] Please see Figure 5 In some embodiments, the adjusting member 2 includes an adjusting rod 21, on which an active transmission part is provided. The mounting bracket 1 is provided with a driven transmission part that cooperates with the active transmission part. The active transmission part and the driven transmission part are connected in a driving connection to drive the mounting bracket 1 to move relative to the adjusting member. Specifically, the active transmission part and the driven transmission part are located within the mounting space 14. The driven transmission part is integrally formed with the mounting bracket 1, or the driven transmission part is fixed to the mounting space 14 of the mounting bracket 1 by means of snap-fitting, welding, etc.
[0036] Please see Figures 5 to 7 In one embodiment, the active transmission unit and the driven transmission unit are a gear 211 and a rack 15, respectively. Specifically, the rack 15 is disposed on the inner surface of the side plate 12 or the mounting plate 11 and extends along the longitudinal direction of the vehicle, while the gear 211 is disposed in the middle of the adjusting member 2. By rotating the adjusting member 2, the gear 211 and the rack 15 mesh with each other, driving the mounting bracket 1 to move along the longitudinal direction of the vehicle, thereby driving the door trim panel 3 to move along the longitudinal direction of the vehicle, thus compensating for the matching tolerance between the door trim panel 3 and the dashboard and improving the pass rate. For example, the position adjustment mechanism can achieve precise adjustment of the door trim panel 3 within the range of [0, 0.6] mm in the front-rear direction of the vehicle. This allows the door trim panel 3 to move 0.2 mm, 0.4 mm, or 0.6 mm relative to the door sheet metal in front of or behind the vehicle, without the need for a complicated disassembly and assembly process. This reduces maintenance time and mold repair costs. Compared with traditional methods, it shortens the matching time, increases the fault tolerance rate in the assembly process, and is easy to operate, reducing the possibility of rework and improving assembly quality and efficiency.
[0037] Understandably, this utility model does not limit the extension direction of the rack 15. The rack 15 can also extend along the height direction of the vehicle. In this embodiment, the rotating adjusting member 2, through the meshing of the gear 211 and the rack 15, can drive the mounting bracket 1 to move along the height direction of the vehicle, thereby driving the door trim panel 3 to move along the height direction of the vehicle. It should be noted that in other embodiments, the active transmission unit and the driven transmission unit can also be selected from existing technologies such as lead screw and nut screw pairs, or cam mechanisms, to achieve the function of converting rotational motion into linear motion.
[0038] Please continue reading. Figure 5 The adjusting member 2 also includes a driving part 22 and a limiting part 23, which are located at the left and right ends of the adjusting member 2. Figure 1 As shown, at both ends of the adjusting member 2, gear 211 is disposed between the limiting part 23 and the driving part 22. The driving part 22 is used to drive gear 211 to rotate under the action of a control force, thereby driving rack 15 to move along its length direction. The limiting part 23 is used to abut against the door sheet metal to limit the relative position of adjusting member 2 and mounting bracket 1 along the axial direction of adjusting rod 21. Optionally, the end of the driving part 22 is prismatic, so that the shape of the driving part 22 can be adapted to wrenches and other tightening tools for easy adjustment.
[0039] Specifically, the limiting part 23 includes a limiting flange 231 and a positioning post 232. In this embodiment, the area of the door sheet metal corresponding to the limiting part 23 is provided with a limiting hole. During installation, the positioning post 232 passes through the limiting hole and can rotate relative to the door sheet metal, while the limiting flange 231 abuts against the door sheet metal. In one embodiment, the positioning post 232 is provided with a guide section 233, the diameter of which gradually decreases in the direction away from the limiting flange 231, to guide the positioning post 232 into the limiting hole, thereby facilitating installation. Optionally, the guide section 233 has a recessed area on its outer peripheral surface forming multiple evenly distributed weight-reducing grooves, which is beneficial for weight reduction.
[0040] Please see Figure 1 and Figure 3 In one embodiment, the mounting plate 11 has mounting holes 111 through which the positioning post 232 passes. Optionally, the mounting holes 111 are located in the middle of the mounting plate 11 and are rectangular, oblong, or round. Optionally, the mounting plate 11 of the mounting bracket 1 has at least two limiting flanges 112 corresponding to the mounting holes 111. The limiting flanges 112 are L-shaped or I-shaped, and are located on opposite sides of the mounting holes 111. Furthermore, the at least two limiting flanges 112 are approximately symmetrical to each other, improving stability. Figure 3As shown, two limiting flanges 231 are approximately symmetrically arranged on the upper and lower sides of the mounting hole 111. The limiting flanges 231 and the limiting flange 112 abut against each other to prevent the adjusting member 2 from tilting or wobbling, which helps the adjusting member 2 maintain a horizontal position and improves the stability of the meshing between the gear 211 and the rack 15. In addition, the limiting flange 112 can reduce the requirements for machining accuracy and installation error to a certain extent, thereby improving installation efficiency.
[0041] Please see Figure 4 In one embodiment, the end of the side panel 12 away from the mounting plate 11 is bent and extended to form a fixing plate 13, and the mounting bracket 1 is fixedly connected to the door trim panel 3 through the fixing plate 13. Optionally, the edge of the fixing plate 13 is bent and extended to form a reinforcing edge 132, which improves the rigidity and bending resistance of the mounting plate 11, thereby enhancing the structural strength and stability of the fixing plate 13, so that the mounting bracket 1 is more securely installed to the door trim panel 3.
[0042] Optionally, the side plate 12 protrudes from its outer surface toward the fixing plate 13 to form a first reinforcing rib 121. The first reinforcing rib 121 is triangular, trapezoidal, or other shapes, which improves the structural strength of the mounting bracket 1. Optionally, the mounting space 14 of the mounting bracket 1 is also provided with a plurality of second reinforcing ribs 122 to further improve the structural strength of the mounting bracket 1.
[0043] Please see Figure 1 In some embodiments, one of the fixing plate 13 and the door trim panel 3 is provided with a connecting post 31, and the other is provided with a connecting hole 131 corresponding to the connecting post 31. The connecting post 31 passes through the connecting hole 131 and is fixedly connected to the part around the connecting hole 131.
[0044] In one embodiment, the fixing plate 13 is provided with a connecting hole 131, and the door trim panel 3 is provided with a connecting post 31 protruding from it. The connecting hole 131 is located in the area of the fixing plate 13 corresponding to the connecting post 31. During installation, the connecting post 31 passes through the connecting hole 131 and is fixedly connected to the fixing plate 13 by welding. The number of connecting holes 131 is at least two, and at least two connecting holes 131 are respectively provided on the upper and lower sides of the mounting plate 11. Optionally, one or more connecting holes 131 are also provided on either the left or right side of the mounting plate 11 to improve the stability of the connection. It should be noted that the mounting bracket 1 and the door trim panel 3 can also be fixedly connected by fasteners, such as bolts or studs. In this embodiment, the position adjustment mechanism also includes a nut that mates with the fasteners. Specifically, the door trim panel 3 has a fixing hole (not shown in the figure), and the connecting hole 131 is located in the area of the fixing plate 13 corresponding to the fixing hole. The bolt passes through the fixing hole and the connecting hole 131 and is threadedly connected to the nut, so that the door trim panel 3 and the fixing plate 13 are sandwiched between the bolt head and the nut.
[0045] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
