Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to door interior panel clips and vehicles. Background Technology

[0002] In existing technologies, the snap-fit ​​structures used for door trim panels often fail to match the door sheet metal properly, exhibiting significant vertical assembly deviations, inaccurate positioning, and large installation tolerances. Furthermore, the existing snap-fit ​​structures do not fit snugly against the door trim panels, requiring considerable force to insert and insufficient force to remove them. This results in an unstable connection between the snap-fit ​​structure and the door trim panel. During vehicle operation, the snap-fit ​​structure is prone to dislodging from the mounting holes due to shaking and bumps, leading to quality issues such as vibration, noise, and air leakage in the door trim panel.

[0003] Therefore, there is a need to provide improved door trim panel clips and vehicles to at least partially address the shortcomings of the existing technology. Utility Model Content

[0021] According to a first aspect of the present invention, a door interior panel clip 10 is provided. Figure 1 A perspective view of a door interior panel clip 10 according to an embodiment of the present invention is shown. Figure 2 It shows Figure 1 The diagram shows a three-dimensional view of the door trim panel clip 10 from another perspective. Figure 3 It shows Figure 1The diagram shows a top view of the door trim panel clip 10. Figure 4 It shows Figure 3 The diagram shows a cross-sectional view of the door trim panel clip 10 taken along line AA, in which the door sheet metal 20, the inner water cutter 30, and the door trim panel 40 are schematically shown in the installed state with the door trim panel clip 10 by double-dotted lines.

[0022] To facilitate understanding of this utility model, the directions mentioned herein are defined as follows: The vehicle length extension direction is defined as parallel to the X direction, wherein the direction from the front to the rear of the vehicle is the positive X direction, and the direction from the rear to the front of the vehicle is the negative X direction; the vehicle width extension direction is defined as parallel to the Y direction, wherein the direction from the driver's side to the passenger side of the vehicle is the positive Y direction, and the direction from the passenger side to the driver's side of the vehicle is the negative Y direction; the vehicle height extension direction is defined as parallel to the Z direction, wherein the direction from the bottom to the top of the vehicle is the positive Z direction, and the direction from the top to the bottom of the vehicle is the negative Z direction.

[0023] like Figures 1 to 4 As shown, the door interior panel clip 10 includes a latching member 100, an mounting part 200, and a connecting part 300 disposed between the latching member 100 and the mounting part 200 and connecting the latching member 100 and the mounting part 200 together. The latching member 100 is used to install onto the door sheet metal 20 of the vehicle, the mounting part 200 is used to install onto the door interior panel 40 of the vehicle, and the second receiving space 300A, which will be described in detail later, formed by the connecting part 300, the latching member 100, and the mounting part 200, is used to install the inner water cutter 30.

[0024] like Figures 1 to 3 As shown, the engaging member 100 has a first side portion 101, a second side portion 102, and a transition portion 103 connecting the first side portion 101 and the second side portion 102. The second side portion 102 of the engaging member 100 is connected to the connecting portion 300, and the first side portion 101, the second side portion 102, and the transition portion 103 form a first receiving space 100A. The lower end of the first receiving space 100A has an opening for inserting a door sheet metal 20 from the lower end of the engaging member 100. The first side portion 101 and the second side portion 102 are generally plate-shaped, and the distance between the first side portion 101 and the second side portion 102 in the Y direction is greater than the thickness of the door sheet metal 20, so as to accommodate the door sheet metal 20 in the first receiving space 100A. Optionally, the first side portion 101, the second side portion 102, and the transition portion 103 are integrally formed to improve the overall rigidity and fatigue resistance of the engaging member 100.

[0025] The assembly 200 includes an assembly body 210 and at least one latch, which has a gap with the assembly body 210 and at least partially protrudes from the portions of the assembly body 210 located on both sides of the latch. The assembly body 210 of the assembly 200 is connected to the connecting portion 300. Specifically, as... Figures 1 to 4 As shown, the assembly 200 has a first assembly side (not shown), a second assembly side (not shown), and a bent region 211 connecting the first assembly side and the second assembly side. At least one of the two sides extending from the bent region 211 (i.e., the first assembly side and the second assembly side) is provided with a locking foot. This locking foot connects to the bent region 211, enabling the assembly body 210 to provide reliable mechanical support for at least one locking foot, effectively withstanding the insertion force during assembly, vibrations generated during use, and external loads under various working conditions, ensuring the positioning stability and load-bearing reliability of at least one locking foot in the Z direction. Specifically, in this embodiment, each of the first assembly side and the second assembly side is provided with a locking foot. It should be understood that in other embodiments not shown in this utility model, the assembly may be provided with only one locking foot.

[0026] Optionally, the main body 210 of the assembly and at least one clamping foot are integrally formed to improve the overall rigidity and fatigue resistance of the assembly 200.

[0027] In addition, such as Figures 1 to 4 As shown, an abutment member 212 is provided at the end of the upper part of the assembly body 210 that extends away from the bending area 211. The abutment member 212, together with the connecting part 300 and the second side part 102 of the engaging part 100, defines a receiving part 300A with a U-shaped groove structure. The receiving part 300A is used to receive the inner water cutter 30.

[0028] In this embodiment, the assembly 200 includes a first locking foot 220 and a second locking foot 230, wherein the first locking foot 220 and the second locking foot 230 are respectively disposed on two sides extending from the bending region 211. Specifically, the first locking foot 220 is disposed on the side of the first assembly, and the second locking foot 230 is disposed on the side of the second assembly. That is, the first locking foot 220 and the second locking foot 230 are disposed opposite each other in the Z direction and are connected to each other via the assembly body 210, specifically, via the bending region 211.

[0029] like Figures 1 to 3As shown, the first latch 220 has a first latch end 220A and a second latch end 220B. The first latch end 220A is spaced apart from the assembly body 210 and protrudes from the assembly body 210 in the positive Z direction at portions located on both sides of the first latch 220. The second latch end 220B is connected to the bending region 211 of the assembly body 210, forming a "U"-shaped gap between the first latch 220 and the assembly body 210. Similarly, the second latch 230 is connected to the bending region 211 and forms a "U"-shaped gap with the assembly body 210, protruding from the assembly body 210 in the negative Z direction at portions located on both sides of the second latch 230.

[0030] According to the technical solution of this utility model, by setting a reasonable gap between the latch and the main body 210 of the fitting, when the fitting 200 of the door interior panel clip 10 is inserted into the mounting hole of the door interior panel 40, the latch can undergo effective elastic deformation, while the main body 210 of the fitting remains basically rigid and undeformed. This design ensures, on the one hand, that the main body 210 of the fitting can firmly abut against the inner water cutter 30 without affecting the positioning accuracy of the inner water cutter 30; on the other hand, by setting a gap between the latch and the abutment component 212 used to support the inner water cutter 30, the assembly insertion force when the latch is inserted into the mounting hole of the door interior panel 40 is significantly reduced; furthermore, the overall structure of the door interior panel clip 10 is simple, requiring no complex processing steps, and is easy and reliable to operate. This optimized design of the door interior panel clip 10 ensures both ease of assembly and structural stability during use.

[0031] Optionally, the engaging component 100, the mounting component 200, and the connecting portion 300 are integrally formed, thereby avoiding stress concentration problems caused by traditional processes such as bolting, welding, or bonding, and improving the tensile strength and fatigue life of the overall structure of the door interior panel clip 10. It should be understood that in other embodiments not shown in this utility model, the engaging component 100, the mounting component 200, and the connecting portion 300 can also be fixedly connected by mechanical connection methods such as welding, but it must be ensured that the connection strength between them meets predetermined conditions.

[0032] In one embodiment, the transition portion 103 is provided with a limiting protrusion 110 protruding toward the first receiving space 100A. Specifically, the transition portion 103 adopts an arc-shaped structure design and has an arc-shaped inner surface and an arc-shaped outer surface (not shown) arranged opposite to each other. The limiting protrusion 110 protrudes from the arc-shaped inner surface. When the door sheet metal 20 is inserted into the engaging member 100, the edge of the door sheet metal 20 will precisely abut against the limiting protrusion 110 to achieve positioning. The design of the limiting protrusion 110 effectively solves the problem of poor matching between the engaging member and the door sheet metal in the prior art, and significantly improves the assembly accuracy. In addition, the overall design of the limiting protrusion 110 is simple in structure, low in cost, and can effectively reduce installation tolerances.

[0033] Optionally, the limiting protrusion 110 can be a raised structure protruding from the arc-shaped inner surface toward the first receiving space 100A, or it can be a tongue provided on the transition portion 103 as shown in this embodiment. The following is a detailed description of this embodiment.

[0034] like Figures 1 to 4 As shown, the tongue has a first tongue end and a second tongue end, wherein the first tongue end is spaced apart from the transition portion 103, and the second tongue end is connected to the transition portion 103, forming a "U"-shaped gap between the tongue and the transition portion 103. The tongue is configured such that the first tongue end protrudes towards the first receiving space 100A, so that when the door sheet metal 20 is inserted into the engaging member 100, the edge of the door sheet metal 20 will precisely abut against the first tongue end of the tongue for positioning. Figure 4 As shown in detail.

[0035] The first locking foot 220 is provided with a first bent portion 221 having a stop surface 221B. Specifically, as shown in the figure... Figures 1 to 4 As shown, the first bending portion 221 is disposed at the first latch end 220A of the first latch 220. The first bending portion 221 bends toward the second latch 230, so that the first bending portion 221 forms an upwardly convex protruding structure extending in the X direction, and the stop surface 221B of the first bending portion 221 is approximately perpendicular to the Y direction. Figure 4 As shown in detail, when the assembly 200 is inserted into the mounting hole of the door interior panel 40, the edge of the first clip end 220A positions the mounting hole of the door interior panel 40, and the stop surface 221B of the first bent portion 221 abuts against the abutting surface 41 at the mounting hole of the door interior panel 40, so that the abutting surface 41 at the mounting hole abuts against the stop surface 221B is approximately parallel to the stop surface 221B. This effectively prevents the assembly 200 from coming out of the mounting hole of the door interior panel 40 through surface contact, ensuring the assembly reliability of the door interior panel clip 10 and the door interior panel 40.

[0036] It should be understood that the second latch 230 can be configured in a similar manner to further reduce the insertion force required for the latch of the door trim panel clip to be inserted into the mounting hole, and to increase the pull-out force required for the latch to be removed from the mounting hole. The specific structure and connection method of the second latch 230 will not be described in detail here.

[0037] Optionally, the angle between the stop surface 221B and the Z-direction is greater than or equal to 0° and less than or equal to 5°. Correspondingly, the angle between the stop surface 221B and the abutting surface 41 of the door interior panel 40 is greater than or equal to 0° and less than or equal to 5°. This configuration effectively increases the pull-out force required for the assembly 200 to detach from the mounting hole. It should be noted that the magnitude of the pull-out force can be flexibly adjusted by adjusting the angle between the stop surface 221B and the Z-direction and the structural strength of the first bend 221. For example, by appropriately reducing the angle between the stop surface 221B and the Z-direction, the anti-detachment effect and assembly stability between the assembly 200 and the mounting hole of the door interior panel 40 can be improved.

[0038] In one embodiment of this utility model, the first locking foot 220 is provided with a through hole 222. Specifically, the through hole 222 is located in the middle of the first locking foot 220. This design, on the one hand, significantly improves its elastic deformation capacity by reducing the rigidity of the locking foot, making the assembly process of the fitting 200 and the door interior panel 40 smoother; on the other hand, the hollow structure effectively reduces material usage, achieving lightweight design while ensuring structural strength. It should be understood that the size and position of the through hole 222 need to be optimized to ensure that the first locking foot 220 can produce uniform elastic deformation under force without stress concentration.

[0039] Optionally, the second side portion 102 includes a second side portion body and a first latch 121 disposed on the second side portion body. The first latch 121 has a first latch end and a second latch end disposed opposite to each other, wherein the first latch end is a free end and spaced apart from the second side portion body, and the second latch end is connected to the second side portion body, such that a "U"-shaped gap is formed between the first latch 121 and the second side portion body. The first latch end bends toward the first side portion 101 and is capable of elastic deformation in a direction away from the first side portion 101. In its natural state, the distance between the hook-shaped region of the first latch end bending toward the first side portion 101 and the first side portion 101 is less than the thickness of the door sheet metal 20, such that when the door sheet metal 20 is installed in the engaging member 100, the first latch 121 can cooperate with the first side portion 101 to clamp the door sheet metal 20, thereby restricting the movement of the door sheet metal 20 in the Y direction.

[0040] Optionally, the second side portion 102 also includes a second latch 122 and a third latch 123 disposed on the second side portion body. Similarly, the second latch 122 and the third latch 123 each form an "L"-shaped gap with the second side portion body and have free ends. The hook-shaped areas at the free ends of the second latch 122 and the third latch 123 that bend toward the first side portion 101 are not on the same straight line as the hook-shaped areas at the ends of the first latch that bend toward the first side portion 101. Thus, when installing the door sheet metal 20, the misaligned bending of the second latch 122 and the third latch 123 with the first latch 121 forms a triangular abutment structure, increasing the abutment force points in the Y direction and further stabilizing the positioning of the door sheet metal 20 in the Y direction, thereby improving the overall assembly stability.

[0041] In a second aspect of this utility model, a vehicle is provided. The vehicle includes the aforementioned door interior panel latch 10.

[0042] Although the present invention has been described in conjunction with embodiments, those skilled in the art will understand that the above description and drawings are exemplary and not restrictive, and the present invention is not limited to the disclosed embodiments. Various modifications and variations are possible without departing from the spirit of the present invention.
