[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In related technologies, to ensure the stability of trim installation, the edges of the trim are typically bent so that the bent portion is embedded in the injection-molded edging after injection molding. However, the edge bending of the trim is generally achieved through stamping, which can result in a fogged appearance at the stamping location, affecting the trim's aesthetics. This application provides an edging assembly, a glass assembly, and a vehicle that can effectively cover the bent portions of both sides of the trim's edges with the injection-molded edging, improving the trim's aesthetics.

[0032] Please see Figure 1 In one embodiment, this application provides a glass assembly 10, which includes an edge-sealing assembly 11 and a glass component 12. The edge-sealing assembly 11 includes an injection-molded edge-sealing 100, at least partially covering the edge of the glass component 12.

[0033] This application makes the following improvements to the aforementioned edge-binding assembly 11.

[0034] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the edging assembly 11 provided in this application may further include a trim 200 and an insert 300, with the insert 300 connected to the trim 200. The edging 100, trim 200, and insert 300 are integrally injection molded. The trim 200 includes a main body 210 and a bent portion 220 connected to the edge of the main body. The bent portion 220 is bent relative to the main body 210, and at least a portion of the injection-molded edging 100 covers the surface of the bent portion 220.

[0035] The edge-wrapping assembly 11 described in this application solves the problem of exposed bent portions and a foggy appearance on the edge of the trim 200 by having at least a portion of the injection-molded edge-wrapping 100 covering the surface of the bent portion 220, thus improving the aesthetic appearance of the edge-wrapping assembly 11. Furthermore, the edge-wrapping assembly 11 adds an insert 300 to the structure of the trim 200, which helps to indirectly position the trim 200 within the injection mold. This eliminates the need for the surface of the bent portion 220 of the trim 200 to directly contact and position with the injection mold, allowing the injection-molded edge-wrapping 100 to smoothly cover the surface of the bent portion 220 of the trim 200 during injection molding, ensuring the aesthetic appearance of the edge-wrapping assembly.

[0036] It should be noted that in related technologies, at least one of the bent portions 220 on both sides of the decorative element 200 needs to be positioned against the injection mold during injection molding. This results in the surface of at least one of the bent portions 220 on both sides of the decorative element 200 being exposed and unable to be covered by the injection molding edging 100. Therefore, the edging assembly 11 of this application adds an insert 300 to the structure of the decorative element 200 to transfer the need for direct positioning of the decorative element 200 and the injection mold to the insert 300. However, this arrangement is not only applicable to cases where the edges of the decorative element 200 have a stamping and bending requirement, but also applicable to cases where the edges of the decorative element 200 do not have a stamping and bending requirement. In other words, in some other embodiments, regardless of the design of the appearance shape of the decorative element 200, it can be indirectly positioned by adding the insert 300, which is not limited here.

[0037] Of course, in this application, the addition of the insert 300 can be set up to address the situation where the edge of the trim 200 has a stamping and bending requirement. It can solve the problem of the exposed bent part of the edge of the trim 200 being foggy and improve the appearance of the edging assembly 11.

[0038] For more details, please refer to Figure 4 In some embodiments, the main body 210 has an inner surface and an outer surface that are opposite to each other. The insert 300 is connected to the inner surface of the main body 210. The insert 300 is provided with a positioning part 301. The positioning part 301 is configured to be positioned and connected with a preset point of the injection mold when the injection molding edge 100 is injection molded, so that at least a portion of the injection molding edge 100 covers the surface of the bent part 220.

[0039] Specifically, the edge-wrapping assembly 11 of this application, by providing a positioning part 301 in the insert 300, helps to meet the positioning requirements between the insert 300 and the injection mold and improves the positioning accuracy between the insert 300 and the injection mold.

[0040] It should be noted that the outer surface of the aforementioned main body 210 is configured as the side facing outwards and used for display. Correspondingly, the side facing away from the aforementioned outer surface is configured as the inner surface of the main body 210, which is used to connect with the insert 300.

[0041] Additionally, it is worth noting that in this embodiment, at least a portion of the aforementioned injection-molded edge 100 covers the surface of the bent portion 220, which includes two scenarios: "the injection-molded edge 100 only covers the surface of the bent portion 220" or "the injection-molded edge 100 covers the surface of the bent portion 220 and also extends beyond the structure to cover the surface of the main body portion 210".

[0042] Specifically, in both of the aforementioned scenarios, the injection-molded edging 100 is designed to completely cover the surface of the bent portion 220 to address the issue of exposed matte finish on the surface of the bent portion 220. When the injection-molded edging 100 is configured to cover only the surface of the bent portion 220, the outer surface of the main body 210 is fully exposed, thereby maximizing the exposed area of ​​the main body 210 and fully utilizing the decorative function of the trim 200.

[0043] When the injection molding edge band 100 is configured to cover the surface of the bent portion 220 and also extend beyond the structure to cover the surface of the main body portion 210, the injection molding edge band 100 can be allowed to have an excessive injection operation allowance during the injection molding process, thus reducing the injection molding difficulty of the injection molding edge band 100.

[0044] It should be noted that the bent portion 220 can be provided on one side edge of the main body 210, or it can be provided on both sides simultaneously; the bent portion 220 can be bent towards the direction close to the insert 300, or it can be bent in other directions, as long as the injection-molded edge 100 can cover the surface of the bent portion 220. This embodiment is described using the example of bending on both sides and bending towards the direction close to the insert 300, but it is not limited to this.

[0045] In some embodiments, combined with Figure 3 and Figure 4 As shown, the bent portion 220 is bent relative to the main body portion 210 and forms a transition boundary line 221. The injection-molded edging 100 extends from the transition boundary line 221 toward the main body portion 210. Thus, the transition boundary line 221 can provide a reference or set a standard for the extension width of the injection-molded edging 100, allowing users to precisely control the extension width of the injection-molded edging 100 based on the position of the transition boundary line 221. This reduces the injection molding difficulty of the injection-molded edging 100, thereby ensuring that the injection-molded edging 100 can completely cover the bent portion 220 while the main body portion 210 has sufficient exposed area, improving the appearance aesthetics of the trim 200.

[0046] It should be noted that the aforementioned transition boundary line 221 can be a tangent line between the bent portion 220 and the main body portion 210. Understandably, the plane containing the main body portion 210 can be roughly understood as a plane, and the plane containing the bent portion 220 can be roughly understood as an arc surface. The aforementioned transition boundary line 221 is correspondingly configured as the connecting tangent line between the arc surface and the plane. Of course, the plane containing the main body portion 210 can also be configured as an arc surface with a certain curvature. In this case, the transition boundary line 221 can be understood as the connecting line between the arc surface containing the main body portion 210 and the arc surface containing the bent portion 220.

[0047] Preferably, please refer to Figure 4The portion of the injection molding edge 100 extending from the transition boundary line 221 toward the main body 210 can be configured to have a preset width D1. The preset width D1 can be greater than or equal to 0.5mm, such as 0.5mm, 0.6mm, 0.7mm or 0.8mm. This allows the injection molding edge 100 to have an excess injection allowance of at least 0.5mm, reducing the injection molding difficulty of the injection molding edge 100.

[0048] It is worth noting that in some embodiments, during the stamping process, the hazy appearance of the edge of the trim 200 not only occurs on the surface of the bent portion 220, but may also occur on the surface of the main body 210 near a small portion of the width of the bent portion 220. Therefore, according to the above embodiments of this application, by having the injection-molded edge banding 100 at least partially cover the surface of the bent portion 220 and extend from the transition boundary line 221 toward the main body 210, it is helpful to further cover the hazy appearance of the main body 210 of the trim 200 with the injection-molded edge banding 100, thereby further improving the aesthetic appearance of the edge banding assembly.

[0049] Please see Figure 2 and Figure 5 In some embodiments, at least two positioning parts 301 may be provided, and at least two positioning parts 301 are provided at both ends of the insert 300 in the length direction. This helps to fix both ends of the insert 300 to ensure the positioning stability of the insert 300 in the injection mold.

[0050] Understandably, in this embodiment, the number of positioning parts 301 can be configured as 2, 3, 4, or 5, etc. Correspondingly, the injection mold is provided with a number of preset points that correspond one-to-one with the positioning parts 301 to ensure the precise positioning of the insert 300.

[0051] It should be noted that before positioning the positioning part 301 of the insert 300, the decorative part 200 and the insert 300 can be pre-positioned, and then the positioning of the decorative part 200 in the injection mold can be indirectly achieved through the precise positioning of the positioning part 301. The pre-positioning operation of the decorative part 200 and the insert 300, as well as the positioning operation of the positioning part 301 and the injection mold, can be adaptively adjusted according to the final position of the decorative part 200 in the injection mold. For example, the connection position between the decorative part 200 and the insert 300 can be adjusted, or the positioning position of the positioning part 301 on the insert 300 can be adjusted. These details will not be elaborated upon here.

[0052] Optionally, the aforementioned positioning part 301 may be configured as a positioning hole, but not limited to. Correspondingly, the injection mold may be provided with a positioning post that is compatible with the positioning hole at the corresponding positioning point. The positioning hole can be engaged with the positioning post to achieve precise positioning of the insert 300 as a whole.

[0053] Please continue reading. Figure 1 In some embodiments, the glass assembly 12 and the decorative element 200 are arranged at intervals, combined with Figure 2 and Figure 3 As shown, at least a portion of the insert 300 extends beyond the trim 200 and is disposed on one side of the glass assembly 12. At least a portion of the injection molding edging 100 fills the space between the extended portion of the insert 300 and the glass assembly 12. After the injection molding edging 100 integrally injection molds the insert 300, the glass assembly 12, and the trim 200, the insert 300 can simultaneously support or reinforce the glass assembly 12 and the trim 200, thus helping to improve the overall structural strength of the injection molding.

[0054] It should be noted that the phrase "at least part of the insert 300 extends beyond the trim 200 and is disposed on one side of the glass assembly 12" means that the projection of the insert 300 in the thickness direction of the injection molding edge 100 can overlap with the trim 200, and also includes a portion of the projection overlapping with the glass assembly 12.

[0055] Please see Figure 3 and Figure 5 In some embodiments, the insert 300 may include a positioning body 310 and at least two pads 320, with the pads 320 spaced apart on the positioning body 310. The inner surface of the ornament 200 abuts against each of the pads 320, thus achieving multi-point support for the ornament 200.

[0056] Specifically, in this embodiment, the pad 320 not only maintains the supporting and positioning function of the ornament 200, but also forms an injection gap x between the ornament 200 and the positioning body 310. This injection gap x helps the injection-molded edge 100 to fill during injection molding, thereby improving the connection strength between the ornament 200, the insert 300 and the injection-molded edge 100.

[0057] Optionally, the connection between the aforementioned pad 320 and the positioning body 310 may be, but is not limited to, post-assembly or two-material injection molding.

[0058] Optionally, in some embodiments, the hardness of the pad 320 can be configured to Shore A65-80, and the hardness of the positioning body 310 can be configured to be greater than Shore D90. This allows the pad 320 to be relatively softer, so as to absorb the installation deviation of the trim 200 and improve the fit between the trim 200 and the pad 320. Meanwhile, the hardness of the positioning body 310 can be relatively harder, so as to improve the overall structural strength.

[0059] Please see Figure 6In some embodiments, the pad 320 may include a main pad surface 321 and bent pad surfaces 322 respectively connected to both sides of the main pad surface 321. Correspondingly, refer back to Figure 4 The main body 210 and the main pad surface 321 abut against each other and limit each other, and the bent part 220 and the corresponding bent pad surface 322 abut against each other and limit each other. This helps to improve the compatibility between the ornament 200 and the pad 320, improve the installation limiting effect of the pad 320 on the ornament 200, and prevent the ornament 200 from shifting. The structure is simple and reliable.

[0060] Please see Figure 4 In some embodiments, the pad 320 has a protrusion 323 in the extending direction of the bent pad surface 322, and an clearance D2 is provided between the end of the bent portion 220 and the protrusion 323. The clearance D2 can be greater than or equal to 0.5 mm, such as 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1.0 mm, which helps to avoid structural interference between the trim 200 and the pad 320.

[0061] It should be noted that the aforementioned protrusion 323 is a structure formed during the processing of the main pad surface 321 and the bent pad surface 322 of the pad 320.

[0062] In this embodiment, the provision of a clearance gap D2 between the end of the bent portion 220 and the protrusion 323 helps optimize the structural arrangement between the bent portion 220 and the protrusion 323, thereby resolving the structural interference problem between the trim 200 and the pad 320. Furthermore, it is understood that this injection gap x also facilitates filling of the injection molding edging 100, thus further increasing the filling volume and range of the injection molding edging 100, and further improving the strength of the connection between the trim 200 and the insert 300 through the injection molding edging 100.

[0063] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the surface of the positioning body 310 is provided with ribs 311, and the pads 320 are provided with grooves 324 that engage with the ribs 311 for positioning. This helps to improve the installation stability of each pad 320 on the positioning body 310. In addition, each pad 320 is spaced apart along the length of the ribs 311, so that the user can arrange the required number of pads 320 along the length of the ribs 311 according to actual needs to ensure the support stability of the decorative piece 200.

[0064] It should be noted that, in this embodiment, when the ornament 200 is deformed by external force, the ability of the ornament 200 to resist deformation is related to the number of pads 320.

[0065] Understandably, as the number of pads 320 increases, the number of support points supporting the ornament 200 can be increased, thereby correspondingly improving the ornament 200's ability to resist external forces and avoid compression dents.

[0066] Therefore, users can design the number of pads 320 according to actual needs, so as to achieve the effect of multi-point support for the trim 200, and also provide injection gap x through the padding effect of the pads 320 to increase the connection strength between the trim 200 and the insert 300.

[0067] Please see Figure 6 Optionally, in some embodiments, the pad 320 may be provided with a preset thickness D3 along the length direction of the rib 311. The preset thickness D3 can be 5mm-10mm, such as 5mm, 6mm, 7mm, 8mm, 9mm or 10mm. In this way, while ensuring the structural strength of the pad 320, the excessive occupation of the space of the injection gap x can be reduced, so as to ensure the filling amount of the injection edge 100 in the injection gap x, thereby ensuring the connection strength between the trim 200 and the insert 300.

[0068] In some embodiments, an adhesive (not shown) may be provided on the main pad surface 321, and the inner surface of the main body 210 may be bonded to the adhesive. This helps to ensure the connection stability between the main body 210 and the main pad surface 321. At the same time, it also helps to simplify the steps of installing and fixing the trim 200 and improve the installation efficiency of the trim 200 on the pad 320.

[0069] According to another aspect of this application, this application also provides a vehicle that may include the aforementioned edging assembly 11, or the vehicle may include the aforementioned glass assembly 10.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
