Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to a lower door trim panel, a door assembly, and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, more and more car models are adopting the installation of door trim panels. Among them, the lower door trim panel (hereinafter referred to as the door trim panel) is usually installed at the lower end of the door to cover the metal edge of the door, preventing the door sheet metal from being bumped, scratched, impacted by road water or gravel, or corroded by mud and sand, thus playing a good protective role. At the same time, it can also increase the vehicle's aesthetics and perceived value.

[0003] Currently, when assembling door trim panels onto the bottom edge of the door, the bottom edge of the door is typically inserted into the limiting groove of the door trim panel along the Z-axis direction (i.e., the vertical direction of the vehicle), and the locating pin on the door trim panel is aligned with the locating groove on the bottom edge of the door trim panel. Then, the door trim panel is slapped onto the bottom edge of the door trim panel so that the locating pin on the door trim panel engages with the locating groove on the bottom edge of the door trim panel, thus completing the assembly. This assembly method requires a relatively large Z-axis clearance for the door trim panel. Because the sill beam below the door is fitted with a skirt trim panel, and the gap between the skirt trim panel and the door is a Z-axis gap, when the front door is opened to its maximum angle, the middle and rear ends of the bottom edge of the front door are located on the outside of the skirt trim panel, providing a large Z-axis installation space. However, the front end of the bottom edge of the front door is still directly above the skirt trim panel, which easily leads to assembly difficulties, incomplete assembly, or scratches during assembly of the door trim panel, affecting the workshop assembly cycle, production capacity, and subsequent after-sales maintenance. Utility Model Content

[0004] The problem this utility model solves is: how to improve the convenience of assembling the lower trim panel of a car door.

[0005] To solve the above problems, this utility model provides a lower door trim panel, a door assembly, and a vehicle.

[0006] In a first aspect, the present invention provides a door trim panel, including an outer door trim panel and an inner door trim panel extending along the front-rear direction of the vehicle. The outer door trim panel includes an outer panel body and a first flange. The first flange is disposed at one end of the outer panel body facing the front direction of the vehicle and is located inside the outer panel body. The inner door trim panel is connected to the inner side of the outer panel body.

[0007] The inner panel of the door trim panel has a limiting groove that runs through the front-back direction on the side opposite to the outer panel body, and the first flange has an avoidance groove that runs through the front-back direction. The avoidance groove and the limiting groove are arranged opposite to each other in the front-back direction, and the upper ends of the limiting groove and the avoidance groove are open.

[0008] Optionally, the outer panel of the door trim panel further includes a second flange, which is disposed at one end of the outer panel body facing the rear direction of the vehicle and is disposed opposite to the first flange, and the inner panel of the door trim panel is located between the first flange and the second flange.

[0009] Optionally, the end of the clearance groove away from the outer panel body is open.

[0010] Optionally, the upper end of the outer panel body is provided with an abutment portion, which is located on the inner side of the outer panel body and above the first flange and the second flange, and the abutment portion is used to form a line-surface contact with the outer side of the door sheet metal.

[0011] Optionally, the side of the abutting portion that abuts against the door sheet metal has an arc-shaped structure.

[0012] Optionally, the abutting portion extends along the front-rear direction, and in the front-rear direction, there is a gap between the end face of the abutting portion facing the front direction and the end face of the first flange facing the front direction, and there is also a gap between the end face of the abutting portion facing the rear direction and the end face of the second flange facing the rear direction.

[0013] Furthermore, the portion of the abutting part that abuts against the door sheet metal has a distance between it and the upper surface of the outer panel body in the vertical direction of the vehicle.

[0014] Optionally, the limiting groove has a protrusion on the groove wall away from the outer panel body, and the protrusion is used to abut against the lower inner side of the door sheet metal.

[0015] Secondly, this utility model provides a car door assembly, including a car door sheet metal and a lower door trim panel as described above, wherein the lower door trim panel is connected to the lower end of the car door sheet metal.

[0016] Optionally, the door assembly further includes a sealing strip extending along the front-rear direction of the vehicle. The sealing strip is connected to the inner side of the inner panel of the lower door trim panel and abuts against the inner side of the door sheet metal. The sealing strip also covers the clearance groove of the lower door trim panel.

[0017] Thirdly, this utility model provides a vehicle, including the lower door trim panel as described above or the door assembly as described above.

[0018] The beneficial effects of this utility model's lower door trim panel are as follows: A first flange is provided at the front end of the outer panel body of the door trim panel to enhance its structural strength. The first flange also shields the inner door trim panel, protecting it from impacts such as road water or gravel. A limiting groove extending in the front-to-back direction is provided on the inner side of the inner door trim panel, with its upper end open to allow the lower end of the door sheet metal to be inserted. Simultaneously, a clearance groove extending in the front-to-back direction is provided at the position corresponding to the limiting groove on the first flange 12, with its upper end open. Thus, when assembling the lower door trim panel on the front door, the front door can be opened to its maximum angle first. Then, the assembled lower door trim panel is placed directly below the front door sheet metal with its front end higher than its rear end. Finally, the front end of the lower door trim panel is inserted from the upper end of the clearance groove into the lower end of the door sheet metal. The remaining parts of the lower door trim panel are inserted from the upper end of the limiting groove to the lower end of the door sheet metal. At this time, the entire lower door trim panel is located on the outside of the skirt panel trim panel, and the front end of the lower door trim panel can be located in the middle of the lower end of the door sheet metal, so that the rear end of the lower door trim panel extends beyond the rear end of the door sheet metal. Therefore, it is necessary to push the lower door trim panel forward along the length of the lower door trim panel until the front end of the bottom edge of the door sheet metal passes through the clearance groove and is inserted into the limiting groove. In this way, the front end of the lower door trim panel can be assembled to the front end of the bottom edge of the door sheet metal by sliding horizontally, without the need for vertical assembly. This solves the problem of insufficient assembly space for the front end of the lower door trim panel in the Z-axis direction, and also ensures that the lower door trim panel can be assembled in place, reducing assembly scratches. Moreover, the entire assembly process is simple and convenient, which can greatly improve the assembly efficiency of the lower door trim panel and the convenience of later maintenance.

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Although some embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0032] In the attached diagram, the Z-axis represents the vertical direction, i.e., up and down, with the positive direction of the Z-axis representing up and the negative direction representing down. The X-axis represents the horizontal direction and is designated as the front and back position, with the positive direction of the X-axis representing the front and the negative direction representing the back. The Y-axis represents the left and right position, with the positive direction of the Y-axis representing the left and the negative direction representing the right. It should be noted that the aforementioned representations of the Z, Y, and X axes are merely for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0034] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0035] In related technologies, when assembling a door trim panel onto the bottom edge of a car door, the bottom edge of the door is typically first inserted into the limiting groove of the door trim panel along the Z-axis direction (i.e., the vertical direction of the vehicle), and the locating pin on the door trim panel is aligned with the locating groove on the bottom edge of the door. Then, the door trim panel is slapped onto the bottom edge of the door so that the locating pin on the door trim panel engages with the locating groove on the bottom edge of the door, thus completing the assembly. This assembly method requires a relatively large clearance space in the Z-axis direction for the door trim panel. Because the door sill beam below the door is fitted with a skirt panel, and the gap between the skirt panel and the door is a Z-axis gap, when the front door is opened to its maximum angle, the middle part and the rear end of the bottom edge of the front door are located on the outside of the skirt panel, providing a large installation space in the Z-axis direction. However, the front end of the bottom edge of the front door is still located directly above the skirt panel, resulting in a small installation space in the Z-axis direction at the front end of the door panel. This makes it easy for the door panel to encounter problems such as difficult assembly, improper assembly, or assembly scratches during assembly, affecting the workshop assembly cycle, production capacity, and after-sales maintenance.

[0036] In view of the problems existing in the above-mentioned related technologies, this utility model provides a lower door trim panel, a door assembly, and a vehicle.

[0037] Combination Figures 1 to 5 As shown, the present invention provides a door lower trim panel 100, which includes a door trim panel outer panel 1 and a door trim panel inner panel 2 extending along the front-rear direction of the vehicle. The door trim panel outer panel 1 includes an outer panel body 11 and a first flange 12. The first flange 12 is disposed at one end of the outer panel body 11 facing the front direction of the vehicle and is located inside the outer panel body 11. The door trim panel inner panel 2 is connected to the inside of the outer panel body 11.

[0038] The inner panel 2 of the door trim panel is provided with a limiting groove 21 that runs through the front-back direction on the side opposite to the outer panel body 11. The first flange 12 is provided with a relief groove 14 that runs through the front-back direction. The relief groove 14 and the limiting groove 21 are arranged opposite to each other in the front-back direction, and the upper ends of the limiting groove 21 and the relief groove 14 are open.

[0039] It should be noted that the entire lower door trim panel 100, as well as the outer door trim panel 1 and the inner door trim panel 2 of the lower door trim panel 100, are all elongated plate structures. After the lower door trim panel 100 is installed at the lower end of the door sheet metal 200, the lower door trim panel 100, the outer door trim panel 1, and the inner door trim panel 2 are aligned along the front-rear direction of the vehicle (i.e., Figure 4 Arranged along the X-axis, the length direction of the lower door trim panel 100, the outer door trim panel 1, and the inner door trim panel 2 is the vehicle's front-to-back direction, i.e., the X-axis direction, or simply the front-to-back direction. The positive direction of the X-axis represents the forward direction of the vehicle, and the negative direction represents the rearward direction. The end of the outer door trim panel 1 facing the forward direction is the front end of the outer door trim panel 1. Correspondingly, the vehicle's vertical direction is... Figure 4 The Z-axis direction, also known as the up-down direction, corresponds to the left-right direction of the vehicle. Figure 5 The Y-axis direction, also known as the left and right direction.

[0040] It should also be noted that the outer side of the lower door trim panel 100, the outer door trim panel 1, and the inner door trim panel 2 refers to the side facing outwards from the vehicle. Correspondingly, the inner side of the lower door trim panel 100, the outer door trim panel 1, and the inner door trim panel 2 refers to the side facing outwards from the vehicle. The outer side of the outer door trim panel 1 is also the side of the outer door trim panel 1 that is away from the inner door trim panel 2. The inner side of the outer door trim panel 1 is also the side of the outer door trim panel 1 that faces the inner door trim panel 2. The outer side of the inner door trim panel 2 is also the side of the inner door trim panel 2 that faces the outer door trim panel 1. The inner side of the inner door trim panel 2 is also the side of the inner door trim panel 2 that is away from the outer door trim panel 1. For example, for the lower door trim panel 100 installed on the door sheet metal 200 on the left side of the vehicle, the left side of the lower door trim panel 100, the outer door trim panel 1, and the inner door trim panel 2 are its outer sides, and the right side of the lower door trim panel 100, the outer door trim panel 1, and the inner door trim panel 2 are its inner sides.

[0041] Specifically, such as Figure 5As shown, the lower door trim panel 100 mainly consists of an outer door trim panel 1, an inner door trim panel 2, and a decorative trim strip 3. The outer door trim panel 1 includes an outer panel body 11 and a first flange 12. The first flange 12 is located on the inner front end of the outer panel body 11. The inner door trim panel 2 is located on the inner side of the outer panel body 11, and the outer panel body 11 and the inner door trim panel 2 can be detachably connected by means of, for example, snap-fit ​​and / or screw-fit. The decorative trim strip 3 can be fixed to the outer lower end of the outer panel body 11 by snap-fit. The inner door trim panel 2 can be installed on the outer lower end of the door sheet metal 200 by snap-fit. The inner side of the inner door trim panel 2 is provided with a limiting groove 21 that runs through the front and rear directions, that is, the front and rear ends of the limiting groove 21 are open, and the upper end of the limiting groove 21 is also open. The first flange 12 is provided with a relief groove 14 that runs through the front and rear directions. That is, the front and rear ends of the relief groove 14 are also open. At the same time, the upper end of the relief groove 14 is also open, so that the relief groove 14 is roughly a notch structure. Moreover, the relief groove 14 is located in front of the limiting groove 21 and is directly opposite to the limiting groove 21 in the front and rear directions.

[0042] In this embodiment, the lower door trim panel 100 can improve the structural strength of the outer door trim panel 1 by providing a first flange 12 at the front end of the outer panel body 11 of the outer door trim panel 1, and use the first flange 12 to cover the inner door trim panel 2, protecting the inner door trim panel 2 from impacts such as road water or gravel; by providing a limiting groove 21 that runs through the front and rear directions on the inner side of the inner door trim panel 2, and leaving the upper end of the limiting groove 21 open, the lower end of the door sheet metal 200 can be inserted into it; at the same time, by providing a clearance groove 14 that runs through the front and rear directions at the position of the first flange 12 corresponding to the limiting groove 21, and leaving the upper end of the clearance groove 14 open, when the lower door trim panel 100 is installed on the front door, such as Figure 7As shown, the front door can be opened to its maximum angle first. Then, the assembled lower door trim panel 100 is placed directly below the front door sheet metal 200 with the front end higher than the rear end. Next, the front end of the lower door trim panel 100 is inserted from the upper end of the clearance groove 14 to the lower end of the door sheet metal 200. The remaining parts of the lower door trim panel 100 are then inserted from the upper end of the limiting groove 21 to the lower end of the door sheet metal 200. At this point, the entire lower door trim panel 100 is located outside the skirt panel 400, and the front end of the lower door trim panel 100 can be located in the middle of the lower end of the door sheet metal 200, so that the rear end of the lower door trim panel 100 extends beyond the rear end of the door sheet metal 200. Therefore, it is also necessary to follow the car... Push the lower door trim panel 100 forward along its length until the front end of the bottom edge of the door sheet metal 200 passes through the clearance groove 14 and is inserted into the limiting groove 21. In this way, the front end of the lower door trim panel 100 can be assembled to the front end of the bottom edge of the door sheet metal 200 by sliding along the horizontal direction, without the need for assembly in the vertical direction. This can solve the problem of insufficient assembly space for the front end of the lower door trim panel 100 in the Z-axis direction, and at the same time, it can ensure that the lower door trim panel 100 can be assembled in place, reducing assembly scratches. Moreover, the whole assembly process is simple and convenient, which can greatly improve the assembly efficiency of the lower door trim panel 100 and the convenience of later maintenance.

[0043] Optionally, combined Figure 1 and Figure 2 As shown, the outer panel 1 of the door trim panel also includes a second flange 13, which is disposed at one end of the outer panel body 11 facing the rear direction of the vehicle and is disposed opposite to the first flange 12, and the inner panel 2 of the door trim panel is located between the first flange 12 and the second flange 13.

[0044] In this optional embodiment, the first flange 12 and the second flange 13 are respectively the front flange and the rear flange of the outer door trim panel 1. In this way, based on the first flange 12 at the front end of the outer panel body 11, the second flange 13 at the rear end of the outer panel body 11 is provided to further enhance the structural strength of the outer door trim panel 1. Moreover, by placing the inner door trim panel 2 between the first flange 12 and the second flange 13, the flanges can be used to cover the front and rear ends of the inner door trim panel 2, preventing, for example, road water or gravel from entering the interior of the lower door trim panel 100 or even the interior of the door, thereby protecting the door.

[0045] Furthermore, combined Figure 1 and Figure 2 As shown, the end of the clearance groove 14 furthest from the outer panel body 11 is open. This provides more adjustment space for the lower door trim panel 100 in the left and right directions, thereby further improving the convenience of assembly. Furthermore, the machining process of the clearance groove 14 in this embodiment is simpler.

[0046] Furthermore, combined Figure 2 and Figure 8 As shown, the outer panel body 11 of the outer door trim panel 1 is provided with a first positioning post 16, and the inner door trim panel 2 is provided with a first positioning hole 23. The first positioning post 16 is inserted into the first positioning hole 23. The first positioning hole 23 can be located above the limiting groove 21. This facilitates pre-positioning using the first positioning post 16 and the first positioning hole 23 during the assembly of the lower door trim panel 100, thereby improving the convenience and accuracy of assembly.

[0047] Optionally, combined Figure 5 , Figure 6 and Figure 8 As shown, the upper end of the outer panel body 11 is provided with an abutment portion 15. The abutment portion 15 is located on the inner side of the outer panel body 11 and above the first flange 12 and the second flange 13. The abutment portion 15 is used to form a line-surface contact with the outer side of the door sheet metal 200.

[0048] When the lower door trim panel 100 is attached to the door sheet metal 200, the upper end of the lower door trim panel 100 will collide with the parting line of the door sheet metal 200, which can easily cause paint chipping at the parting line of the door sheet metal 200. Therefore, this embodiment provides an abutment portion 15 on the upper inner side of the outer panel body 11, and makes the upper end of the lower door trim panel 100 make line-surface contact with the door sheet metal 200 at the abutment portion 15, thereby reducing the contact area between the lower door trim panel 100 and the parting line of the door sheet metal 200, and thus reducing the risk of paint chipping at the parting line of the door sheet metal 200.

[0049] Optionally, combined Figure 6 As shown, the end of the abutment portion 15 away from the outer panel body 11 has an arc-shaped structure, and the abutment portion 15 is used to abut against the door sheet metal 200 at the arc-shaped structure. In this way, it can be ensured that a line-to-surface contact can be formed between the abutment portion 15 and the door sheet metal 200. Moreover, compared with using an edge structure to form a line-to-surface contact with the door sheet metal 200, the arc-shaped structure makes the upper inner side of the outer panel body 11 smoother, which can reduce assembly scratches.

[0050] Optionally, combined Figure 8 As shown, the abutment portion 15 extends in the front-rear direction, and in the front-rear direction, there is a gap between the end face of the abutment portion 15 facing the front direction and the end face of the first flange 12 facing the front direction, and there is also a gap between the end face of the abutment portion 15 facing the rear direction and the end face of the second flange 13 facing the rear direction.

[0051] In this optional embodiment, the abutment portion 15 can be a long strip-shaped protrusion extending in the front-to-back direction. Compared with a multi-segment protrusion structure, this is not only easier to manufacture, but also makes the structure at the upper end of the door trim panel 1 more continuous and stronger. Furthermore, there is a gap between the front end face of the abutment portion 15 and the front end face of the first flange 12, and a gap between the rear end face of the abutment portion 15 and the rear end face of the second flange 13. These two gaps can be set to 1.5mm or 2mm, respectively. This improves the ease of disassembly while ensuring a certain matching gap.

[0052] Optionally, combined Figure 1 , Figure 3 and Figure 5 As shown, a protrusion 22 is provided on the groove wall of the limiting groove 21 away from the outer door trim panel 1. The protrusion 22 is used to abut against the lower inner side of the door sheet metal 200. In this way, the groove wall of the limiting groove 21 away from the outer door trim panel 1 forms an abutment contact with the lower inner side of the door sheet metal 200 at the protrusion 22, which can reduce the contact area between the lower door trim panel 100 and the lower edge of the door sheet metal 200, thereby reducing the risk of paint peeling at the lower edge of the door sheet metal 200.

[0053] In addition, the protruding end of the protrusion 22 can be made into an arc surface structure so that the protrusion 22 and the lower edge of the door sheet metal 200 can form a line-surface contact, thereby further reducing the risk of paint peeling at the lower edge of the door sheet metal 200.

[0054] Furthermore, combined Figure 3 and Figure 8 As shown, a second positioning post 24 is provided on the side of the inner door panel 2 opposite to the outer panel body 11. The second positioning post 24 is used to insert into the second positioning hole (not shown in the figure) on the door sheet metal 200. In this way, it is convenient to use the second positioning post 24 and the second positioning hole for pre-positioning when assembling the lower door panel 100, so as to improve the convenience and accuracy of assembly.

[0055] Furthermore, combined Figure 8 As shown, the inner panel 2 of the door trim panel is provided with a buckle 25 on the side opposite to the outer panel body 11, and the lower end of the door sheet metal 200 is provided with a slot (not shown in the figure). The buckle 25 is used to engage with the slot at the lower end of the door sheet metal 200. In this way, the snap-fit ​​engagement between the lower door trim panel 100 and the door sheet metal 200 can be achieved. Moreover, the snap-fit ​​installation and fixing method can improve assembly efficiency and shorten the production cycle.

[0056] Combination Figure 4 As shown in the figure, an embodiment of the present invention provides a door assembly, including a door sheet metal 200 and a lower door trim panel 100 as described above, wherein the lower door trim panel 100 is connected to the lower end of the door sheet metal 200.

[0057] The beneficial effects of the door assembly in this embodiment are the same as those of the lower door trim panel described above, and will not be repeated here.

[0058] Optionally, combined Figure 5 and Figure 9 As shown, the door assembly also includes a sealing strip 300 extending along the front-rear direction of the vehicle. The sealing strip 300 is connected to the inner side of the door trim panel 2 of the lower door trim panel 100 and abuts against the inner side of the door sheet metal 200. The sealing strip 300 also covers the clearance groove 14 of the lower door trim panel 100.

[0059] In this optional embodiment, the sealing strip 300 can be fixed to the inner side of the inner panel 2 of the door trim panel by means of, for example, snap-fit ​​or adhesive. In this way, the sealing strip 300 is provided on the inner side of the lower door trim panel 100. The sealing strip 300 can extend along the side wall of the limiting groove 21, and its two ends extend to the first flange 12 and the second flange 13 of the outer panel 1 of the door trim panel, respectively. By using the sealing strip 300 to cover the clearance groove 14 of the lower door trim panel 100 and the gap between the clearance groove 14 and the limiting groove 21, it is possible to prevent, for example, water or gravel from the road surface from entering the interior of the door through the clearance groove 14 or the gap, thereby achieving a good sealing effect. Furthermore, the upper end of the sealing strip 300 can be positioned close to the opening of the limiting groove 21. When the limiting groove 21 is inserted into the lower end of the door sheet metal 200, the upper end of the sealing strip 300 can abut against the inner side of the door sheet metal 200 to improve the sealing effect of the limiting groove 21 and prevent road water or gravel from entering the interior of the door from the upper opening of the limiting groove 21.

[0060] This utility model provides a vehicle, including the lower door trim panel as described above or the door assembly as described above.
