Description

[0002] With the development of science and technology, people have placed higher demands on the comfort and stability of vehicle driving. Multi-sided edge trim can effectively improve the sealing, sound insulation, waterproofing, and noise reduction functions of vehicles. Therefore, more and more vehicles are using multi-sided edge trim in areas such as the windshield, rear window, and sunroof. Multi-sided edge trim generally includes, but is not limited to, three-sided, four-sided, or other numbers of edge trims. Specifically, it consists of multiple edge trims with the same or different cross-sections, which are spliced ​​together in corresponding areas, for example, by welding, to form a whole.

[0029] 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.

[0030] As described in the background art, the multi-sided edge banding strips in the related art are prone to cracking or breakage defects when subjected to external pressure, thereby losing the sealing and other performance properties of the multi-sided edge banding strips. The inventors have found that the reason for this problem is that the two adjacent edge banding strips are welded together with a planar cross-section of approximately 45° or 180°. The small area of ​​the planar cross-section results in a weak bonding force between the two adjacent edge banding strips, which makes them prone to cracking or breakage defects.

[0031] For the reasons mentioned above, this application provides a multi-sided edge banding strip, glass assembly, and vehicle that can improve the structural strength at the joint, prevent cracks or breaks, and improve the product qualification rate.

[0032] See Figure 1 , Figure 1 An exploded structural diagram of a polygonal binding strip according to an embodiment of this application is shown. Figure 2 and Figure 3 They are shown respectively Figure 1 The diagram shows two different perspective views of the first edging strip 10 and the second edging strip 20. One embodiment of this application provides a polygonal edging strip, comprising a first edging strip 10 and a second edging strip 20. One end of the first edging strip 10 and one end of the second edging strip 20 are abutted together. One end of the first edging strip 10 has a first mating surface 11 and a second mating surface 12 arranged at an angle. One end of the second edging strip 20 has a third mating surface 21 corresponding to the position of the first mating surface 11 and a fourth mating surface 22 corresponding to the position of the second mating surface 12. The first mating surface 11 and the third mating surface 21 are fitted together, and the second mating surface 12 and the fourth mating surface 22 are fitted together.

[0033] In the aforementioned polygonal edge banding strip, the first edge banding strip 10 adopts a first mating surface 11 and a second mating surface 12 set at an angle to respectively attach and connect the third mating surface 21 and the fourth mating surface 22 of the second edge banding strip 20. Compared with the two edge banding strips in related technologies that are connected by separate planar cross sections, this method can increase the mating area, thereby improving the structural strength at the connection point, avoiding cracks or breaks, greatly improving the product qualification rate, and reducing the probability of product failure.

[0034] Please see Figure 2 and Figure 3 In some embodiments, the specific connection methods between the first mating surface 11 and the third mating surface 21 include, but are not limited to, various connection methods such as fusion welding, bonding, and welding. Similarly, the specific connection methods between the second mating surface 12 and the fourth mating surface 22 include, but are not limited to, various connection methods such as fusion welding, bonding, and welding. In this embodiment, the specific connection method between the first mating surface 11 and the third mating surface 21 is fusion welding, and the specific connection method between the second mating surface 12 and the fourth mating surface 22 is fusion welding, thereby making the first edge banding strip 10 and the second edge banding strip 20 fused together to form a whole. The structural strength at the joint is stable and reliable, and it is not easy for gaps or breakage defects to occur.

[0035] In some embodiments, the included angle between the first mating surface 11 and the second mating surface 12 can be flexibly adjusted and set according to actual needs, including but not limited to 30°, 45°, 60°, 90°, 120°, 135°, 150°, etc. In this embodiment, the first mating surface 11 and the second mating surface 12 are specifically arranged perpendicularly to each other, which results in a more regular shape compared to other angles and makes it easier to process by methods such as milling, stamping, and die casting. Since the third mating surface 21 and the fourth mating surface 22 are respectively arranged corresponding to the first mating surface 11 and the second mating surface 12, the included angle between the third mating surface 21 and the fourth mating surface 22 is the same as the included angle between the first mating surface 11 and the second mating surface 12.

[0036] In some embodiments, the first binding strip 10 in the above embodiments is not limited to having a first mating surface 11 and a second mating surface 12, but may also have mating surfaces that are respectively angled to the first mating surface 11 and the second mating surface 12. Correspondingly, the second binding strip 20 is not limited to having a third mating surface 21 and a fourth mating surface 22, but may also have mating surfaces that are respectively angled to the third mating surface 21 and the fourth mating surface 22. In this way, when the number of mating surfaces increases, the mating area can be increased, thereby improving the structural strength at the connection point, avoiding cracks or fractures, greatly improving the product qualification rate, and reducing the probability of product failure.

[0037] Please see Figure 2 and Figure 3 In some embodiments, the first mating surface 11 and the corresponding third mating surface 21 have matching shapes. That is, the first mating surface 11 and the corresponding third mating surface 21 have the same shape and the same area. In this way, when the first mating surface 11 and the third mating surface 21 are fitted together, the outer wall surface of the connection part can be flat and seamless, thereby improving the product performance.

[0038] In some embodiments, the second mating surface 12 and the corresponding fourth mating surface 22 have matching shapes. That is, the second mating surface 12 and the corresponding fourth mating surface 22 have the same shape and the same area. When the second mating surface 12 and the fourth mating surface 22 are fitted together, the outer wall surface of the connection part can be flat and seamless, thereby improving product performance.

[0039] Please see Figure 2 and Figure 3In one embodiment, at least two first mating surfaces 11 are provided, each located at a different position, and at least two third mating surfaces 21 are provided, each located at a different position, with each third mating surface 21 corresponding to each first mating surface 11. Thus, by having each first mating surface 11 at a different position corresponding to and connected to each third mating surface 21 at a different position, the mating area can be increased, and the arrangement of the mating surfaces can be more flexible, thereby improving the structural strength at the connection point and preventing cracks or fractures.

[0040] Please see Figure 2 and Figure 3 In some embodiments, the shape and size of each first mating surface 11 can be consistent or different, and can be flexibly adjusted and set according to actual needs. Correspondingly, the shape and size of each third mating surface 21 can be consistent or different.

[0041] Please see Figure 2 and Figure 3 In some embodiments, the first mating surface 11 shown in this embodiment is provided as two, namely the first mating surface 11a and the first mating surface 11b; the third mating surface 21 shown in this embodiment is correspondingly provided as two, namely the third mating surface 21a and the third mating surface 21b. Among them, the first mating surface 11a and the third mating surface 21a are positioned correspondingly and are fitted and connected to each other, and the first mating surface 11b and the third mating surface 21b are positioned correspondingly and are fitted and connected to each other.

[0042] As some alternatives, the first mating surface 11 and the third mating surface 21 can both be set to one or other quantities.

[0043] Please see Figure 2 and Figure 3 In one embodiment, at least two second mating surfaces 12 are provided, each located at a different position, and at least two fourth mating surfaces 22 are provided, each located at a different position, with each fourth mating surface 22 corresponding to each second mating surface 12. Thus, by having each second mating surface 12 at a different position corresponding to and connected to each fourth mating surface 22 at a different position, the mating area can be increased, and the arrangement of the mating surfaces can be more flexible, thereby improving the structural strength at the connection point and preventing cracks or fractures.

[0044] Please see Figure 2 and Figure 3 In some embodiments, the shape and size of each second mating surface 12 can be consistent or different, and can be flexibly adjusted and set according to actual needs. Correspondingly, the shape and size of each fourth mating surface 22 can be consistent or different.

[0045] Please see Figure 2 and Figure 3 In some embodiments, the second mating surface 12 shown in this embodiment is provided as two, namely the second mating surface 12a and the second mating surface 12b; the fourth mating surface 22 shown in this embodiment is correspondingly provided as two, namely the fourth mating surface 22a and the fourth mating surface 22b. The second mating surface 12a and the fourth mating surface 22a are positioned correspondingly and are fitted together, and the second mating surface 12b and the fourth mating surface 22b are positioned correspondingly and are fitted together.

[0046] As some alternatives, the second mating surface 12 and the fourth mating surface 22 can both be set to one, or other quantities.

[0047] Please see Figure 2 and Figure 3 In one embodiment, one end face of the first binding strip 10 is provided with at least one first protrusion 13 protruding along its extension direction, and one end of the second binding strip 20 is provided with a first recess 23 corresponding to the first protrusion 13. The first protrusion 13 is correspondingly disposed in the first recess 23. The first protrusion 13 is provided with a first mating surface 11 and a second mating surface 12, and the inner wall of the first recess 23 is provided with a third mating surface 21 and a fourth mating surface 22. Alternatively, one end face of the second binding strip 20 is provided with at least one second protrusion protruding along its extension direction, and one end of the first binding strip 10 is provided with a second recess corresponding to the second protrusion. The second protrusion is correspondingly disposed in the second recess, and the second protrusion is provided with a third mating surface 21 and a fourth mating surface 22. The inner wall of the second recess is provided with a first mating surface 11 and a second mating surface 12.

[0048] Please see Figures 1 to 3 In some embodiments, the number of first protrusions 13 is not limited to one, but can be multiple. The number of first recesses 23 is the same as the number of first protrusions 13 and is adapted to the first protrusions 13. When the number of first protrusions 13 and first recesses 23 increases, the mating area between the first edge banding strip 10 and the second edge banding strip 20 can be increased, thereby improving the structural strength at the connection point and preventing cracks or breaks.

[0049] Please see Figures 1 to 3 In some embodiments, the number of second protrusions is not limited to one, but can be multiple, and the number of second recesses is the same as the number of second protrusions and is adapted to the number of second protrusions. When the number of second protrusions and second recesses increases, the mating area between the first edge banding strip 10 and the second edge banding strip 20 can be increased, thereby improving the structural strength at the connection position and preventing cracks or breaks.

[0050] Please see Figures 1 to 3In some embodiments, the first protrusion 13 can be located at any position on one end face of the first binding strip 10. Specifically, it can be flexibly adjusted and set according to actual needs, including but not limited to the top, middle, bottom, and side of one end face of the first binding strip 10. The position of the first recess 23 corresponds to the position of the first protrusion 13, so that the first protrusion 13 can be correspondingly installed and fixed in the first recess 23.

[0051] Please see Figures 1 to 3 In some embodiments, the second protrusion can be located at any position on one end face of the second edge banding strip 20. Specifically, it can be flexibly adjusted and set according to actual needs, including but not limited to the top, middle, bottom, and side portions on one end face of the second edge banding strip 20. The position of the second recess corresponds to the position of the second protrusion, so that the second protrusion can be correspondingly installed and fixed in the second recess.

[0052] In some embodiments, the specific shape of the first protrusion 13 can be flexibly adjusted and set according to actual needs, including but not limited to various structural forms such as columns, plates, blocks, and ribs. In this embodiment, the first protrusion 13 is, for example, a rib. The cross-sectional size of the rib at various positions along its extension direction can be consistent, which makes it easier to process, or it can be inconsistent. The specific shape of the second protrusion is similar to that of the first protrusion 13, and will not be described again here.

[0053] Please see Figures 1 to 3 In some embodiments, the length L1 of the first protrusion 13 along its extension direction is greater than or equal to 5 mm; the length L2 of the first recess 23 along its extension direction is greater than or equal to 5 mm. Thus, the length L1 of the first protrusion 13 and the length L2 of the first recess 23 are sufficiently large, which increases the mating area between the first binding strip 10 and the second binding strip 20, thereby improving the structural strength at the connection point and preventing cracks or breaks.

[0054] Please see Figures 1 to 3 In some embodiments, the setting parameters of the second protrusion and the second recess are similar to those of the first protrusion 13 and the first recess 23, and will not be repeated here. Furthermore, the lengths of the other protrusions and corresponding recesses of the first binding strip 10 and the second binding strip 20 are all greater than or equal to 5 mm.

[0055] Please see Figures 1 to 3In some embodiments, the second mating surface 12 is parallel to the extension direction of the first protrusion 13, and the thickness d of the first protrusion 13 in the direction perpendicular to the second mating surface 12 is greater than or equal to 1 mm, which is less than the thickness of the first edge strip in the direction perpendicular to the second mating surface 12. Thus, the thickness d is sufficiently large to improve the structural strength at the connection point and prevent cracks or breaks. Furthermore, it reduces the impact of welding tolerances and ensures a good fit between the welded area and the glass edge.

[0056] Please see Figure 2 and Figure 3 In one embodiment, one end of the first binding strip 10 is provided with a first reinforcing portion 14 protruding along its extension direction, and the first reinforcing portion 14 is connected to the second binding strip 20. And / or, one end of the second binding strip 20 is provided with a second reinforcing portion protruding along its extension direction, and the second reinforcing portion is connected to the first binding strip 10.

[0057] Specifically, the first reinforcing part 14 is provided with a mating surface, such as the second mating surface 12, and the second edge band 20 is provided with a corresponding mating surface, such as the fourth mating surface 22.

[0058] Specifically, the second reinforcing part is provided with a mating surface, which is specifically, for example, a fourth mating surface 22. The first edge banding strip 10 is provided with a corresponding mating surface, which is, for example, a second mating surface 12.

[0059] In some embodiments, the first protrusion 13 and the first reinforcing portion 14 are located on opposite sides of the mating connection position of the second mating surface 12 and the fourth mating surface 22, respectively. Specifically, the mating connection position of the second mating surface 12 and the fourth mating surface 22 is fixed by means including but not limited to fusion bonding or welding. In this way, compared to being provided on the same side of the first edge banding strip 10, the bonding force can be increased to avoid cracks or breakage.

[0060] In some embodiments, the first reinforcing part 14 may include, but is not limited to, various structural forms such as a reinforcing block, reinforcing plate, reinforcing rib, reinforcing column, and reinforcing strip. Similarly, the second reinforcing part may include, but is not limited to, various structural forms such as a reinforcing block, reinforcing plate, reinforcing rib, reinforcing column, and reinforcing strip.

[0061] Please see Figure 2 and Figure 3In some embodiments, the inner periphery of the polygonal edging strip is provided with a step 40 for mounting glass. The first reinforcing part 14 is located on the side of the first edging strip 10 opposite to the supporting surface of the step 40, that is, on the side of the first edging strip 10 opposite to the glass. The first protrusion 13 is located on the other side of the first edging strip 10. Thus, since the first reinforcing part 14 is located on the side of the first edge banding strip 10 away from the support surface of the step 40, the location of the first reinforcing part 14 is not exposed. In addition, the first protrusion 13 is correspondingly located on the outer surface of the first edge banding strip 10, and since the first protrusion 13 is located in the first recess 23, the flatness of the outer surface at the joint position of the first edge banding strip 10 and the second edge banding strip 20 can be guaranteed. Furthermore, the first protrusion 13 is as far away from the step 40 as possible. For example, the maximum thickness of the first protrusion 13 is controlled within a preset range. In other words, the bonding connection position of the second mating surface 12 and the fourth mating surface 22 is far away from the support surface of the step 40, which can reduce the influence of welding tolerance and thus ensure the bonding between the welding part and the glass edge. This is because the bonding between the welding part and the glass edge relies entirely on the bonding between the 3M adhesive and the bottom surface of the glass.

[0062] Please see Figure 2 and Figure 3 In one embodiment, the first binding strip 10 includes a first main structure 101 and a first lip 102 connected to the first main structure 101. Furthermore, the second binding strip 20 includes a second main structure 201 and a second lip 202 connected to the second main structure 201. One end of the first main structure 101 and one end of the second main structure 201 are abutted together, and one end of the first lip 102 and one end of the second lip 202 are abutted together. A first reinforcing portion 14 is connected to one end of the first lip 102 and is connected to the side surface of the second lip 202; and / or, a second reinforcing portion is connected to one end of the second lip 202 and is connected to the side surface of the first lip 102. Thus, since the structural strength of the first lip 102 and the second lip 202 is relatively weak, by setting the first reinforcing part 14 at one end of the first lip 102 and connecting it to the second lip 202, or by setting the second reinforcing part at one end of the second lip 202 and connecting it to the first lip 102, the structural strength at the joint of the first lip 102 and the second lip 202 can be enhanced, thereby effectively preventing cracks or breaks, greatly improving the product qualification rate, and reducing the probability of product failure.

[0063] Please see Figure 2 and Figure 3 In one embodiment, the first main structure 101 and the first lip 102 are integrally injection molded. The second main structure 201 and the second lip 202 are also integrally injection molded. Thus, mass production can be achieved through integral injection molding.

[0064] Please see Figure 2 and Figure 3 In some embodiments, the first main structure 101, the first lip 102, and the first reinforcing part 14 are manufactured using a two-component or multi-component composite extrusion molding process. Thus, during manufacturing, the material of the first main structure 101 differs from the material of the first lip 102 and the material of the first reinforcing part 14, thereby achieving a higher hardness for the first main structure 101 than that of the first lip 102.

[0065] Please see Figure 2 and Figure 3 In some embodiments, the second main structure 201, the second lip 202, and the second reinforcing part are manufactured using a two-component or multi-component composite extrusion molding process. Thus, during manufacturing, the material of the second main structure 201 differs from the material of the second lip 202 and the material of the second reinforcing part, thereby achieving a higher hardness for the second main structure 201 than that of the second lip 202.

[0066] Please see Figure 2 and Figure 3 In one embodiment, the hardness of the first main body structure 101 is 70HA to 90HA; the hardness of the second main body structure 201 is 70HA to 90HA. Thus, the hardness of both the first main body structure 101 and the second main body structure 201 is greater than the hardness of the first lip 102 and the second lip 202, and when the hardness is set to 70HA to 90HA, it has good wear resistance and fatigue resistance.

[0067] The material of the first main structure 101 can be the same as or different from that of the second main structure 201. The material of the first lip 102 can also be the same as or different from that of the second lip 202; no limitation is made here. When the materials of the first main structure 101 and the second main structure 201 are the same, and the materials of the first lip 102 and the second lip 202 are the same, and when the hardness of the first main structure 101 and the second main structure 201 is the same, and the hardness of the first lip 102 and the second lip 202 is the same, the product consistency is good. When the materials of the first main structure 101 and the second main structure 201 are different, and the materials of the first lip 102 and the second lip 202 are different, the design and manufacturing processes are more flexible.

[0068] Please see Figure 2 and Figure 3In some embodiments, the materials of the first main structure 101 and the second main structure 201 are independently set, including but not limited to thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC), etc.

[0069] In some embodiments, the materials of the first lip 102 and the second lip 202 are each independently set, for example, set as soft materials, and specifically including but not limited to EPDM rubber, polyvinyl chloride, styrene, polyurethane, etc.

[0070] Please see Figure 2 and Figure 3 In one embodiment, the first mating surface 11 is perpendicular to the extending direction of the first binding strip 10, and the third mating surface 21 is perpendicular to the extending direction of the second binding strip 20. And / or, the second mating surface 12 is parallel to the extending direction of the first binding strip 10, and the fourth mating surface 22 is parallel to the extending direction of the second binding strip 20.

[0071] Please see Figures 1 to 3 In one embodiment, the first edge banding strip 10 is configured as a corner transition strip, which is correspondingly disposed at the corner of the glass. Furthermore, the second edge banding strip 20 is configured as a side edge banding strip, which is correspondingly disposed at the side of the glass.

[0072] It should be noted that the structural forms of the first edge banding strip 10 and the second edge banding strip 20 can be flexibly adjusted and set according to actual needs. As some optional solutions, the first edge banding strip 10 is set as a side edge banding strip for installation on the side of the glass. In addition, the second edge banding strip 20 is set as a corner transition strip for installation at the corner of the glass.

[0073] Please see Figures 1 to 3 In one embodiment, the multi-sided edge banding strip further includes a third edge banding strip 30. The third edge banding strip 30 is configured as a side edge banding strip, used to be disposed on the side of the glass. One end of the third edge banding strip 30 is connected to the other end of the first edge banding strip 10. Thus, the first edge banding strip 10 is connected to the second edge banding strip 20 and the third edge banding strip 30 at opposite ends, forming an integral structure.

[0074] It should be noted that the connection structure between the third edge banding strip 30 and the first edge banding strip 10 is similar to that between the second edge banding strip 20 and the first edge banding strip 10, and will not be described again here.

[0075] As an example, the structural shape and cross-section of the third edge banding strip 30 can be exactly the same as the structural shape and cross-section of the second edge banding strip 20, or they can be set to different shapes or different cross-sections.

[0076] As an example, the number, type, and arrangement of the mating surfaces of the third edge banding strip 30 can be exactly the same as the number, type, and arrangement of the mating surfaces of the second edge banding strip 20, or they can be different from each other.

[0077] In some embodiments, when the first edge banding strip 10 is configured as a corner edge banding strip, the angle of the corner includes, but is not limited to, 30°, 45°, 60°, 90°, 120°, 135°, 150°, etc., and the included angle between the second edge banding strip 20 and the third edge banding strip 30 is related to the corner angle of the corner edge banding strip.

[0078] Please see Figures 1 to 3 In one embodiment, a glass assembly includes a polygonal edging strip of any of the above embodiments, and also includes glass (not shown in the figures), the polygonal edging strip being disposed on the edge of the glass.

Compared with the two edge banding strips in related technologies that are connected by separate planar cross sections, this method can increase the mating area, thereby improving the structural strength at the connection point, avoiding cracks or breaks, greatly improving the product qualification rate, and reducing the probability of product failure.

[0080] In some embodiments, the glass includes, but is not limited to, a windshield, a rear windshield, side windshields, or a panoramic sunroof.

[0081] Please see Figures 1 to 3 In some embodiments, the inner periphery of the polygonal edging strip is provided with a step 40, and an adhesive tape 41 is provided on the step 40. The edge of the glass is connected to the step 40 by the adhesive tape 41. In this way, the edge of the glass is bonded and fixed to the step 40 by the adhesive tape 41, so as to achieve a tight connection between the edge of the glass and the polygonal edging strip.

[0082] Please see Figures 1 to 3 In some embodiments, tape 41 includes, but is not limited to, 3M tape or other types of adhesive.

[0083] Please see Figures 1 to 3 In some embodiments, a vehicle includes, but is not limited to, an automobile, bus, public transport vehicle, passenger vehicle, train, high-speed train, etc., and the vehicle includes the glass assembly of any of the above embodiments.

[0084] In the aforementioned vehicle, the first edge banding strip 10 adopts a first mating surface 11 and a second mating surface 12 set at an angle to respectively attach and connect the third mating surface 21 and the fourth mating surface 22 of the second edge banding strip 20. Compared with the two edge banding strips in related technologies that are connected by separate planar cross sections, this method can increase the mating area, thereby improving the structural strength at the connection point, avoiding cracks or breaks, greatly improving the product qualification rate, and reducing the probability of product failure.

[0085] It should be noted that the term "injection molding" in this embodiment should be interpreted broadly, referring only to the final product being a single unit, including but not limited to: integral molding of the same material; integral molding of different materials; and sequential injection molding into a single unit (e.g., two-material injection molding).

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0088] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0089] 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.

[0090] 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.
