The snap-fit includes a cap housed within the inner cavity. Along the thickness direction of the mounting plate, both sides of the cap are respectively attached to the mounting plate and the limiting piece. This design allows the buckle to slide into the mounting hole during installation by opening the clearance notch through the elastic deformation of the limiting claw. The buckle then extends into the gap between the mounting plate and the limiting piece, ensuring precise installation. The limiting claw is then released, allowing its limiting end to spring back to its initial position. At this point, both the limiting end and the hole edge are within the annular groove, preventing the buckle from dislodging from the mounting hole along the clearance notch. Simultaneously, the mounting plate and the limiting piece provide a certain degree of clamping for the buckle, reducing buckle wobble and further ensuring it does not dislodge from the mounting hole.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle component technology, and in particular to a snap-on mounting base, a door interior panel, and a vehicle. Background Technology
[0002] Currently, snap-fit structures are widely used in injection-molded parts such as door and tailgate interior panels of vehicles due to their rapid installation characteristics. Taking a door interior panel as an example, a snap-fit mounting seat is provided on the side facing the door sheet metal. After the snap-fit is installed in the snap-fit mounting seat, it can engage with the corresponding part of the door sheet metal, thus securing the door interior panel to the door sheet metal. Commonly used snap-fit mounting seats typically have holes for the snap-fit rod to pass through, and notches are cut on the side of the holes to allow the snap-fit rod to slide into the holes from the periphery. In the assembly line, the operator first slides the snap-fit along the notch into the hole of the snap-fit mounting seat, and then places the door interior panel with the snap-fit attached on a component rack or assembly line to transport it to the area where the door sheet metal is located for assembly. During this process, because the snap-fit is not engaged with the door sheet metal, it remains in a loose state and is prone to falling off due to vibration or shaking during transportation. Utility Model Content
[0003] The main purpose of this utility model is to propose a buckle mounting base, a door interior panel, and a vehicle, aiming to solve the technical problem that the buckle is easy to fall off due to shaking after being installed on the buckle mounting base.
[0004] To achieve the above objectives, this utility model proposes a snap-fit mounting base for mounting snap-fits, comprising:

[0006] A limiting claw is installed in the clearance space, and one end of the limiting claw is fixedly connected to the side plate, while the other end of the limiting claw is a limiting end.
[0007] The buckle has a circumferential groove, and the mounting plate circumferential to the mounting hole is defined as the hole edge;
[0008] Both the limiting end and the hole edge can extend into the annular groove, and the limiting claw can undergo elastic deformation under force to allow the limiting end to open or block the clearance gap.
[0009] The mounting plate and the side plate enclose an inner cavity. The limiting piece is installed in the inner cavity and is parallel to the mounting plate. The buckle includes a buckle cap that is accommodated in the inner cavity. Along the thickness direction of the mounting plate, the two sides of the buckle cap are respectively attached to the mounting plate and the limiting piece.

[0011] In one embodiment, the number of reinforcing plates is at least two, and the at least two reinforcing plates are arranged in parallel and spaced apart.
[0012] In one embodiment, the buckle mounting base further includes a retaining portion, which is housed in the inner cavity and mounted on the side of the reinforcing plate facing the mounting plate, and the retaining portion abuts against the buckle cap.
[0013] In one embodiment, the limiting claw is an elastic sheet, one end of which is fixedly connected to the side plate, and the other end of which is the limiting end. The elastic sheet is a cantilever structure.
[0014] In one embodiment, the elastic sheet is made of one of polyurethane, stainless steel, and spring steel.
[0015] In one embodiment, the limiting claw includes a connecting section and a limiting section.

[0019] According to the technical solution of this utility model, a snap-fit mounting base is used to install snap-fits, including a base body and a limiting claw. The base body includes a mounting plate, a side plate, and a limiting piece. At least a portion of the mounting plate has a side plate mounted on its periphery. The mounting plate has a mounting hole, and a clearance notch is formed on the side of the mounting hole facing the side plate. The side plate has a clearance space communicating with the clearance notch. The limiting claw is installed in the clearance space, and one end of the limiting claw is fixedly connected to the side plate, while the other end of the limiting claw is a limiting end. A circumferential groove is formed in the snap-fit. The mounting plate circumferential to the mounting hole is defined as the hole edge.

The buckle then extends into the gap between the mounting plate and the limiting piece, ensuring precise installation. The limiting claw is then released, allowing its limiting end to spring back to its initial position. At this point, both the limiting end and the hole edge are within the annular groove, preventing the buckle from dislodging from the mounting hole along the clearance notch.

[0037] In the automotive manufacturing industry, the assembly process of vehicle interior parts has a significant impact on production efficiency and product quality. Currently, in key injection-molded parts such as door and tailgate interior panels, snap-fit structures have become a widely used connection method in the industry due to their significant advantage of rapid installation. Taking the door interior panel as an example, a snap-fit mounting seat is designed on the side facing the door sheet metal. This mounting seat serves as the fixing carrier for the snap-fit. After the snap-fit is installed in the snap-fit mounting seat, it is then snapped into the corresponding counterpart of the door sheet metal, thereby achieving a stable connection between the door interior panel and the door sheet metal. Currently, commonly used snap-fit mounting seats on the market typically have holes for the snap-fit rod to pass through, and a specific shaped notch is cut on the side of the hole. The main purpose of this design is to facilitate the smooth sliding of the snap-fit rod into the hole from the periphery, completing the initial installation of the snap-fit.
[0038] In the actual operation of an automobile assembly line, the operator slides the clip along the pre-set notch on the side of the clip mounting base into the hole of the mounting base to ensure that the clip is initially fixed on the mounting base. Then, the door trim panel with the clip attached is placed on a parts rack or assembly line, and transported to the assembly area where the door sheet metal is located via the parts rack or assembly line for subsequent assembly processes. However, according to the applicant's observations and research, during this transportation process, because the clip has not yet been fully engaged with the door sheet metal, the clip is in a continuously loose state. During transportation, vehicle interior parts are inevitably affected by various external forces, such as vibrations from the transport equipment and shaking during vehicle operation. These external forces can easily cause the loose clip to detach from the mounting base, thus affecting the normal assembly of the door trim panel, reducing production efficiency, and potentially even adversely affecting product quality.
[0039] In view of this, the present invention proposes a snap-fit mounting base to solve or at least alleviate the above-mentioned problems.
[0040] Please see Figures 3 to 7 In one embodiment of this utility model, the buckle mounting base 100 is used to mount the buckle 200, and includes a base body 1 and a limiting claw 2. The base body 1 includes a mounting plate 11, a side plate 12, and a limiting piece 13. At least a portion of the mounting plate 11 has a side plate 12 mounted on its periphery. The mounting plate 11 has mounting holes 111, and a clearance notch 112 is formed on the side of the mounting hole 111 facing the side plate 12. The side plate 12 has a clearance space 14 communicating with the clearance notch 112. The limiting claw 2 is mounted in the clearance space 14, and one end of the limiting claw 2 is fixedly connected to the side plate 12, while the other end of the limiting claw 2 is... The limiting end 221; the buckle 200 has a circumferentially formed annular groove 210, defined as: the mounting plate 11 around the mounting hole 111 is the edge of the hole; both the limiting end 221 and the edge of the hole can extend into the annular groove 210, and the limiting claw 2 can undergo elastic deformation under force to open or block the clearance notch 112 of the limiting end 221; the mounting plate 11 and the side plate 12 enclose to form an inner cavity 15, the limiting piece 13 is installed in the inner cavity 15 and is parallel to the mounting plate 11, the buckle 200 includes a buckle cap 220 housed in the inner cavity 15, and along the thickness direction of the mounting plate 11, the two sides of the buckle cap 220 are respectively attached to the mounting plate 11 and the limiting piece 13.
[0041] The specific shape of the buckle mounting base 100 can be adjusted according to its installation position in the door trim panel, and the specific shape is not limited. The base 1 is a hollow shell structure, and its side plates 12 are installed on the outer periphery of the mounting plate 11. The number of side plates 12 is not limited, that is, the inner cavity 15 can be either closed or open. The clearance space 14 is formed in the side plate 12 corresponding to the clearance notch 112. One end of the limiting claw 2 is connected to the side plate 12 and extends towards the clearance notch 112 so as to at least partially block the clearance notch 112.
[0042] According to the technical solution provided in this embodiment, when installing the buckle 200, firstly, the limiting claw 2 is pressed towards the inner cavity 15 so that the limiting end 221 no longer blocks the clearance notch 112; then, the buckle 200 is slid into the mounting hole 111 along the clearance notch 112. During this process, the buckle cap 220 of the buckle 200 needs to be aligned and inserted into the gap between the limiting piece 13 and the mounting plate 11 so that the limiting piece 13 and the mounting plate 11 can play a certain clamping role on the buckle cap 220. After the buckle 200 slides into the mounting hole 111, the buckle 200 should be coaxially set with the mounting hole 111; finally, the limiting claw 2 springs back so that the limiting end 221 can be inserted into the annular groove 210 of the buckle 200. At this time, the edge of the hole of the mounting plate 11 and the limiting end 221 of the limiting claw 2 can both be inserted into the annular groove 210.
[0043] With this configuration, on the one hand, due to the clamping effect of the limiting piece 13 and the mounting plate 11 on the buckle cap 220, and with both the hole edge and the limiting end 221 extending into the annular groove 210, the buckle 200 can be subject to multi-directional limiting effects, thereby reducing the shaking amplitude of the buckle 200 to a certain extent, reducing the possibility of the buckle 200 coming out of the mounting hole 111, and reducing the noise caused by the shaking of the buckle 200. On the other hand, after the limiting claw 2 springs back, it can re-seal the clearance notch 112, and the limiting end 221 itself can also extend into the annular groove 210 after the buckle 200 is installed. Therefore, it can prevent the buckle 200 from coming out of the mounting hole 111 along the clearance notch 112, thus solving the problem that the buckle 200 is easy to come out of the buckle mounting base 100.
[0044] Further, please refer to Figure 4 , Figure 6 and Figure 7 In one embodiment of this utility model, the snap-fit mounting base 100 further includes a reinforcing plate 16, which is housed in the inner cavity 15 and vertically mounted on the side plate 12. The reinforcing plate 16 mounted on the side plate 12 can improve the overall rigidity of the snap-fit mounting base 100, thereby improving the load-bearing capacity of the snap-fit mounting base 100.
[0045] For further information, please continue reading. Figure 4 , Figure 6 and Figure 7 In one embodiment of this utility model, the number of reinforcing plates 16 is at least two, and the at least two reinforcing plates 16 are arranged in parallel and spaced apart. The spacing between the reinforcing plates 16 is set according to the length of the side plate 12. In this embodiment, the spacing between the reinforcing plates 16 can be set to 15mm to 35mm. In this way, the side plate 12 is continuously supported along its length, which helps to prevent the side plate 12 from collapsing during demolding, thereby improving the yield of the snap-fit mounting base 100. At the same time, it can further improve the rigidity of the snap-fit mounting base 100.
[0046] Please see Figure 4 , Figure 6 and Figure 7In one embodiment of this utility model, the snap-fit mounting base 100 further includes a retaining portion 17, which is housed in the inner cavity 15 and installed on the side of the reinforcing plate 16 facing the mounting plate 11. The retaining portion 17 abuts against the snap cap 220. The retaining portion 17 is installed on the reinforcing plate 16 closest to the mounting plate 11 among the multiple reinforcing plates 16. It abuts against the snap cap 220, thereby further limiting the length of the snap 200 based on the limiting plate, avoiding the snap 200 from being unstable due to insufficient strength of the limiting plate or insufficient length of the snap cap 220 extending into the gap between the limiting plate and the mounting plate 11, thus further reducing the shaking amplitude of the snap 200. The shape of the retaining portion 17 can be plate-shaped or block-shaped, and its specific shape is not limited here.
[0047] In one embodiment of this utility model, please refer to Figure 5 The limiting claw 2 is an elastic sheet, one end of which is fixedly connected to the side plate 12, and the other end of which is the limiting end 221. The elastic sheet has a cantilever structure. Thus, when the buckle 200 is installed, the elastic sheet can be pressed towards the inner cavity 15 using the buckle 200 to open the clearance notch 112. After the buckle 200 is installed, the limiting end 221 can spring back to its initial position under the elasticity of the elastic sheet itself and extend into the annular groove 210 of the buckle 200. In one embodiment, the elastic sheet is made of polyurethane, stainless steel, or spring steel, or other alloys or composite plastic materials with elastic deformation capabilities.
[0048] In one embodiment of this utility model, please refer to Figure 5 The limiting claw 2 includes a connecting section 21 and a limiting section 22. The connecting section 21 is connected to the side plate 12, and the limiting section 22 is installed at the end of the connecting section 21 away from the side plate 12. The limiting end 221 is located at the end of the limiting section 22 away from the connecting section 21. The width of the connecting section 21 is smaller than the width of the limiting section 22. The width direction is... Figure 5 The direction indicated by the middle arrow W. This setting allows the limiting segment 22 to block the clearance gap 112 as much as possible, while also increasing the volume of the limiting segment 22 extending into the annular groove 210. This strengthens the limiting effect of the limiting segment 22 on the buckle 200, thereby preventing the buckle 200 from coming out of the gap between the limiting claw 2 and the side plate 12.
[0049] In one embodiment of this utility model, the snap-fit mounting base 100 is a one-piece molded part. The one-piece molding design can avoid the existence of splicing seams in the snap-fit mounting base 100, eliminate the assembly process, and thus help improve the overall strength and production efficiency of the snap-fit mounting base 100.
[0050] This utility model also proposes a car door interior panel, which includes a snap-fit mounting base 100. The specific structure of the snap-fit mounting base 100 is as described in the above embodiments. Since this car door interior panel adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, such as Figure 1 and Figure 2 As shown, the side of the door interior panel facing the door sheet metal is provided with multiple clip mounting seats 100 to connect the door interior panel to the door sheet metal through the multiple clip mounting seats 100 and clips 200.
