Description

Technical Field

[0001] The present invention relates to the technical field of vehicle part processing, and particularly to a hemming assembly, its processing method and a vehicle. Background Art

[0002] A hemming assembly generally includes glass and a hem arranged on the outer periphery of the glass. For occasions with requirements for guiding functions, guide rails and sealing strips are also integrated on the hem. With the continuous development of technologies in the vehicle field, the integration degree of the hemming assembly is getting higher and higher, and the requirements for the appearance effect of the vehicle are also getting higher and higher. A plastic interior trim panel is clamped on the hem to cover the hem inside and play a decorative role. Generally, the plastic interior trim panel and the guide rail on the hemming assembly are similar to a long strip structure. When the length is relatively long, the plastic interior trim panel is prone to warping or twisting by itself. Therefore, a groove can be arranged on the hem along the length direction of the plastic interior trim panel, and the long side of the plastic interior trim panel is clamped in the groove. However, when the hemming assembly is processed to form this groove, there is a problem of difficult demolding. Summary of the Invention

[0003] Aiming at the problem of difficult demolding for the hemming assembly to be provided with the above-mentioned groove, the present invention provides a hemming assembly, its processing method and a vehicle, which can make the demolding process of the hemming assembly more convenient.

[0004] A hemming assembly includes:

[0005] A hem;

[0006] A clamping block, which is integrally injection-molded and connected with the hem, and the clamping block is located at the position on the hem for fixing the interior trim panel, and the clamping block is provided with a groove for the interior trim panel to be clamped into.

[0007] The above solution provides a hemming assembly. When in use, the edge of the interior trim panel can be clamped into the groove, thereby avoiding the warping and twisting of the interior trim panel. Moreover, the groove for the interior trim panel to be clamped into is formed on the clamping block. When injection-molding, the formed clamping block and the mold are used together to define the outer shape of the hem, and then the clamping block and the hem are injection-molded and connected together. And this mold only needs to abut against the outer surface of the clamping block provided with the groove, without inserting into this groove, thereby making the subsequent demolding process more convenient.

[0008] In one embodiment, the hemming assembly further includes glass, the hem is arranged at the edge of the glass, one surface of the clamping block facing the middle of the glass is surface A, and the opening of the groove is formed on surface A.

[0009] In one embodiment, the clamping block is located inside the edge of the glass, and the opening of the groove is more inclined towards the outer side of the glass relative to the bottom of the groove.

[0010] In one embodiment, the snap block is located inside the edge of the glass. The direction from the edge of the glass towards the middle of the glass is the first virtual direction F1, and the direction from the side of the A surface close to the glass towards the side of the A surface far from the glass is the second virtual direction F2. The included angle between the first virtual direction F1 and the second virtual direction F2 is not less than 90°.

[0011] In one embodiment, the snap block is located inside the glass, and the edge wrapping part is arranged between the snap block and the inner side surface of the glass. The distance H between the snap block and the inner side surface of the glass is 1 mm to 2 mm.

[0012] And / or, the surface of the snap block facing the inner side surface of the glass is the B surface, and the width L of the B surface is not less than 5 mm.

[0013] In one embodiment, at least part of the surfaces of the snap block in contact with the edge wrapping are provided with protrusions or depressions.

[0014] In one embodiment, the edge wrapping assembly further includes a guide rail. The guide rail is integrally injection-molded with the edge wrapping. The guide rail has a guide groove, and the opening direction of the guide groove is opposite to the opening direction of the groove.

[0015] In one embodiment, the edge wrapping is at least partially connected between the guide rail and the snap block, and the thickness D of this part of the edge wrapping located between the guide rail and the snap block is 1.5 mm to 2.5 mm.

[0016] In one embodiment, the groove is a strip-shaped groove penetrating the snap block along the length direction of the snap block, and the length direction of the groove is parallel to the guiding direction of the guide groove.

[0017] And / or, a sealing strip is provided in the guide groove.

[0018] In one embodiment, the edge wrapping assembly includes a plurality of the snap blocks, and the plurality of snap blocks are arranged at intervals in sequence along the length direction of the interior trim panel.

[0019] A method for processing an edge wrapping assembly, the edge wrapping assembly being the above-mentioned edge wrapping assembly, and the processing method includes the following steps:

[0020] Place the snap block into the mold so that the surface of the snap block where the opening of the groove is formed abuts against the mold, and the snap block and the mold enclose an injection space.

[0021] Inject the edge wrapping material in a fluid state into the injection space.

[0022] The above solution provides a method for processing a hemming assembly. Before the hemming is injection-molded, the clamping block has been manufactured. During the processing, the clamping block is placed in a mold according to the relative positional relationship with the hemming, and together with the mold, they enclose the injection space. Then, a fluid-shaped hemming material is injected into the injection space. After the hemming material solidifies, the hemming is connected to the clamping block. Since the clamping block exists as a part of the injection space during the injection of the hemming, the mold does not need to be inserted into the groove for clamping the interior trim panel. In other words, the mold only needs to abut against the surface of the opening of the groove formed on the clamping block and does not need to be inserted into the groove, which makes the subsequent demolding process more convenient.

[0023] In one embodiment, the mold is assembled by multiple sub-molds, and the sub-mold that abuts against the surface of the opening of the groove formed on the clamping block is the first sub-mold;

[0024] The processing method further includes the following demolding steps:

[0025] After the fluid-shaped hemming material solidifies, the first sub-mold is separated from the hemming assembly, and the direction in which the first sub-mold separates from the hemming assembly intersects with the opening direction of the groove.

[0026] A vehicle includes an interior trim panel and the above-mentioned hemming assembly. The interior trim panel is assembled inside the hemming, and at least part of the long side of the interior trim panel is clamped in the groove.

[0027] The above solution provides a vehicle. The interior trim panel is assembled inside the hemming in any of the above embodiments, and at least part of the long side of the interior trim panel is clamped in the groove, so as to avoid warping and twisting of the interior trim panel. Moreover, by adopting the hemming assembly in any of the above embodiments, the overall processing process of the vehicle is made more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0043] AsFigure 1 As shown, generally, in order to form a groove 33 for clamping the interior trim panel 35 on the edge trim 31, a convex structure is provided at the corresponding position on the mold, and the edge trim material flows and covers around the convex structure, finally forming the groove 33. During assembly, the long side of the interior trim panel 35 can be clamped in this groove 33, thereby avoiding warping and twisting of the interior trim panel 35.

[0044] The mold is generally composed of multiple sub-molds. As Figure 1 shown, the sub-mold with the aforementioned convex structure is the first sub-mold 10, and the sub-mold for pressing and cooperating with the guide rail 36 is the second sub-mold 20.

[0045] After the edge trim material solidifies, the second sub-mold 20 can move in the direction shown by the arrow N1 in the figure to disengage from the edge trim assembly 30, specifically disengaging from the guide rail 36. The convex structure of the first sub-mold 10 is inserted into the groove 33 of the edge trim 31. If the first sub-mold 10 is demolded in the direction shown by the arrow N2, the concave-convex fit between the convex structure and the groove 33 will hinder the smooth progress of the demolding process. If the first sub-mold 10 is demolded in the direction shown by the arrow N3, the first sub-mold 10 is likely to rub against the glass 34 included in the edge trim assembly 30 during the process of moving relative to the edge trim assembly 30, posing a risk of scratching the glass 34.

[0046] Based on this, in the present application, an edge trim assembly 30 is provided. As Figures 2 to 7 shown, the edge trim assembly 30 includes an edge trim 31 and a clamping block 32. The clamping block 32 is integrally injection-molded and connected to the edge trim 31, and the clamping block 32 is located at the position on the edge trim 31 for fixing the interior trim panel 35. The clamping block 32 is provided with a groove 33 for the interior trim panel 35 to be inserted into.

[0047] As Figure 4 and Figure 5 shown, during use, the edge of the interior trim panel 35 can be inserted into the groove 33, thereby avoiding warping and twisting of the interior trim panel 35.

[0048] Since the groove 33 for the interior trim panel 35 to be inserted into is formed on the clamping block 32, during injection molding, as Figure 2 shown, the formed clamping block 32 can be used together with the mold to define the outer shape of the edge trim 31, and then the clamping block 32 and the edge trim 31 are injection-molded and connected together. And this mold only needs to abut against the outer surface of the clamping block 32 where the groove 33 is provided, without inserting into this groove 33, thereby making the subsequent demolding process more convenient.

[0049] Specifically, as Figure 2As shown, the first sub-mold 10 is in contact or abuts against the surface of the opening of the groove 33 formed on the clamping block 32, but the first sub-mold 10 is not inserted into this groove 33 provided on the clamping block 32. After the edge material solidifies, the first sub-mold 10 can be demolded in the direction shown by the arrow N2, which will neither scratch the glass 34 nor generate excessive resistance due to the mold being inserted into the groove 33, ensuring the smooth progress of the demolding process.

[0050] Moreover, even if there is no glass 34 during the injection molding of the edge 31 and there is no risk of scratching the glass 34, for such a usage scenario, based on the fact that the first sub-mold 10 is not inserted into the groove 33, no matter in which direction the first sub-mold 10 is demolded, its demolding process is still smoother.

[0051] Furthermore, in some embodiments, as Figures 3 to 7 shown, the edge assembly 30 further includes a glass 34, the edge 31 is arranged at the edge of the glass 34, and the clamping block 32 is arranged at the edge of the glass 34 together with the edge 31.

[0052] As Figures 4 to 7 shown, a surface of the clamping block 32 facing the middle of the glass 34 is the A surface 321. The opening of the groove 33 is formed on the A surface 321. The opening of the groove 33 generally faces the middle of the glass 34. When the interior trim panel 35 is stuck in the groove 33, the edge 31 is shielded on one side. As Figure 10 shown, when observed from the inside of the vehicle, there is only a small gap, or even no gap, between the interior trim panel 35 and the glass 34, and the overall visual effect is better.

[0053] Specifically, in one embodiment, as Figures 4 to 6 shown, the clamping block 32 is located inside the edge of the glass 34. When injecting the edge 31, the glass 34, the clamping block 32 and the mold together enclose an injection space. In this application, the inside of the glass 34 refers to the side where the interior trim panel 35 is located with respect to the glass 34, and the side opposite to the inside is the outside of the glass 34.

[0054] Furthermore, as Figure 5 shown, in one embodiment, the opening of the groove 33 is more inclined towards the outside of the glass 34 relative to the bottom of the groove 33. Here, being more inclined towards the outside of the glass 34 means that the opening of the groove 33 has a tendency to be inclined in the direction from the inside of the glass 34 towards the outside of the glass 34. This enables the edge of the interior trim panel 35 to be more firmly stuck in the groove 33, and at the same time makes the gap between the interior trim panel 35 and the glass 34 as small as possible.

[0055] Assume that the direction from the edge of the glass 34 towards the middle of the glass 34 is the first virtual direction F1. Figure 4 In the illustrated embodiment, the opening direction of the groove 33 is generally parallel to the first virtual direction F1. Figure 5 In the illustrated embodiment, the included angle between the opening direction of the groove 33 and the first virtual direction F1 is an acute angle, and the opening direction of the groove 33 has a tendency to face the outside of the glass 34.

[0056] As Figure 5 In the illustrated embodiment, under the limiting action of the groove 33, the long side of the interior trim panel 35 is folded towards the interior of the vehicle relative to the middle part of the interior trim panel 35, and the barb on the long side of the interior trim panel 35 is hooked on the clamping block 32, and the cooperation between the two is closer.

[0057] Further, in some embodiments, as Figure 6 and Figure 7 shown, the direction from the side of the A surface 321 close to the glass 34 towards the side of the A surface 321 far from the glass 34 is the second virtual direction F2. The included angle between the first virtual direction F1 and the second virtual direction F2 is not less than 90°. In this way, the first sub-mold 10 is more likely to be demolded in the direction shown by the arrow N2. Assume that the included angle between the first virtual direction F1 and the second virtual direction F2 is less than 90°, then when the first sub-mold 10 is demolded in the direction shown by the arrow N2, it will still be subject to the resistance exerted by the A surface 321, and the demolding is difficult or even infeasible.

[0058] Specifically, as Figure 7 shown, assume that the part of the A surface 321 on the side of the groove 33 close to the glass 34 is the a1 surface 3211, and the part of the A surface 321 on the side of the groove 33 far from the glass 34 is the a2 surface 3212. The a1 surface 3211 is closer to the middle of the glass 34 than the a2 surface 3212.

[0059] In some embodiments, as Figures 4 to 6 shown, the clamping block 32 is located inside the glass 34, and part of the edge wrapping 31 is arranged between the clamping block 32 and the inner side surface of the glass 34. As Figure 6 shown, the distance H between the clamping block 32 and the inner side surface of the glass 34 is 1 mm to 2 mm. This makes it easier for the edge wrapping material to flow between the clamping block 32 and the inner side surface of the glass 34 during injection molding.

[0060] Further, as Figure 6 and Figure 7As shown, the surface of the clamping block 32 facing the inner side of the glass 34 is the B surface 322, and the width L of the B surface 322 is not less than 5 mm, making the adhesion between the clamping block 32 and the edge 31 more firm.

[0061] As Figure 8 and Figure 9 shown, in some embodiments, at least part of the surfaces of the clamping block 32 in contact with the edge 31 are provided with protrusions 323 or depressions 324.

[0062] Specifically, as Figure 9 shown, the B surface 322 is provided with a plurality of protrusions 323. The protrusions 323 are in contact with the inner side of the glass 34 and are used to define the relative position between the clamping block 32 and the glass 34.

[0063] As Figure 8 and Figure 9 shown, the surface of the clamping block 32 opposite to the A surface 321 is provided with a plurality of depressions 324.

[0064] When the edge 31 is injection-molded, the clamping block 32 and the mold together enclose the injection space. The mold is provided with a positioning rod (not shown in the figure), and at least part of the positioning rod is inserted into the depression 324 to define the relative position between the clamping block 32 and the mold.

[0065] Specifically, the depression 324 provided on the surface of the clamping block 32 opposite to the A surface 321 penetrates the clamping block 32 in a direction perpendicular to the B surface 322.

[0066] Further specifically, as Figure 8 and shown in FIG. 9, the groove 33 is a strip-shaped groove penetrating the clamping block 32 along the length direction. Both the A surface 321 and the B surface 322 are parallel to the length direction of the groove 33. The length direction of the interior trim panel 35 is consistent with the length direction of the groove 33.

[0067] Specifically, the length of the clamping block 32 can be consistent with the length of the interior trim panel 35, and the length of the groove 33 is consistent with the length of the interior trim panel 35, and the interior trim panel 35 is fixed by a single-piece clamping block 32.

[0068] Optionally, in some other embodiments, as Figure 11 shown, the edge assembly 30 includes a plurality of the clamping blocks 32, and the plurality of clamping blocks 32 are arranged at intervals in sequence along the length direction of the interior trim panel 35.

[0069] Further, as Figures 4 to 7As shown, in some embodiments, the hemming assembly 30 further includes a guide rail 36, which is integrally injection-molded and connected to the hemming 31. The guide rail 36 has a guide groove 361, and the opening direction of the guide groove 361 is opposite to the opening direction of the groove 33.

[0070] As Figure 2 shown, the second sub-mold 20 is partially located in the guide groove 361. After the hemming material solidifies, the second sub-mold 20 slides in the direction shown by the arrow N1 and disengages from the hemming assembly 30.

[0071] Further, as Figure 7 shown, in one embodiment, the hemming 31 is at least partially connected between the guide rail 36 and the clamping block 32, and the thickness D of the part of the hemming 31 between the guide rail 36 and the clamping block 32 is 1.5 mm to 2.5 mm. In other words, assuming that the part of the hemming 31 between the guide rail 36 and the clamping block 32 is the first part, the distance between the surface of the guide rail 36 that fits with this first part and the surface of the clamping block 32 that fits with this first part is 1.5 mm to 2.5 mm. This makes it easier for the hemming material to flow between the guide rail 36 and the clamping block 32 during injection molding.

[0072] As Figure 2 shown, when injecting the hemming 31, the guide rail 36, the clamping block 32, the glass 34 and the mold together enclose the injection molding space. It should be noted that in this application, the multiple components together enclosing the injection molding space means that the structure for enclosing the injection molding space includes the multiple components, but not necessarily only these components.

[0073] In another embodiment, the surface of the clamping block 32 opposite to the guide rail 36 is provided with a plurality of protrusions (not shown in the figure), and the protrusions are in contact with the guide rail 36 to define the relative position between the guide rail 36 and the clamping block 32.

[0074] Specifically, in one embodiment, as Figure 6 and Figure 7 shown, the groove 33 is a strip-shaped groove that penetrates the clamping block 32 along the length direction of the clamping block 32, and the length direction of the groove 33 is parallel to the guiding direction of the guide groove 361.

[0075] As Figure 4 and Figure 5As shown, a sealing strip 362 is provided in the guiding groove 361. One long side of the interior trim panel 35 is clamped in the groove 33, and the other long side of the interior trim panel 35 can be clamped on the sealing strip 362. The sealing strip 362 is mainly used to abut against the window glass to achieve the sealing between the window glass and the edge wrapping assembly 30.

[0076] Furthermore, in another embodiment, a vehicle is provided, which includes an interior trim panel 35 and the above-mentioned edge wrapping assembly 30. The interior trim panel 35 is assembled inside the edge wrapping 31, and at least part of the long side of the interior trim panel 35 is clamped in the groove 33.

[0077] For the vehicle provided by the above solution, the interior trim panel 35 is assembled inside the edge wrapping 31 in any of the above embodiments, and at least part of the long side of the interior trim panel 35 is clamped in the groove 33, so that warping and torsion of the interior trim panel 35 can be avoided. Moreover, by adopting the edge wrapping assembly 30 in any of the above embodiments, the overall processing process of the vehicle is made more convenient.

[0078] In another embodiment, a processing method for the edge wrapping assembly 30 is provided. The edge wrapping assembly 30 is the above-mentioned edge wrapping assembly 30, and the processing method includes the following steps:

[0079] Place the clamping block 32 into the mold, as Figure 2 shown, so that the surface of the clamping block 32 where the opening of the groove 33 is formed abuts against the mold, and the clamping block 32 and the mold enclose an injection space;

[0080] Inject the edge wrapping material in a fluid state into the injection space.

[0081] The above solution provides a processing method for the edge wrapping assembly 30. Before injecting the edge wrapping 31, the clamping block 32 has been manufactured. During the processing, the clamping block 32 is placed into the mold according to the relative position relationship with the edge wrapping 31, and together with the mold, they enclose the injection space. Then, the edge wrapping material in a fluid state is injected into the injection space. After the edge wrapping material solidifies, the edge wrapping 31 and the clamping block 32 are connected together. Since the clamping block 32 exists as a part of enclosing the injection space during the injection of the edge wrapping 31, the mold does not need to be inserted into the groove 33 for clamping the interior trim panel 35. In other words, the mold only needs to abut against the surface of the clamping block 32 where the opening of the groove 33 is formed and does not need to be inserted into the groove 33, thus making the subsequent demolding process more convenient.

[0082] As Figure 2 shown, the mold is composed of multiple sub-molds, and the sub-mold that abuts against the surface of the clamping block 32 where the opening of the groove 33 is formed is the first sub-mold 10.

[0083] In some embodiments, the processing method further includes the following demolding step:

[0084] After the edge wrapping material in the fluid state solidifies, disconnect the first sub-mold 10 from the edge wrapping assembly 30, and the direction in which the first sub-mold 10 detaches from the edge wrapping assembly 30 intersects with the opening orientation of the groove 33.

[0085] Specifically, as Figure 2 shown, the first sub-mold 10 moves in a direction perpendicular to the plane where the glass 34 is located and away from the glass 34. For example, as Figure 2 shown by the arrow N2 in
