Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to a panoramic glass assembly and vehicle. Background Technology

[0002] In the current market, automakers are continuously exploring ways to improve the comfort, safety, and aesthetics of vehicles. In this process, traditional metal roofs are gradually shifting towards more innovative and practical designs, such as panoramic sunroofs with larger visible areas in some roofs.

[0003] Currently, car roofs with panoramic glass mainly consist of three layers: the outermost layer is the panoramic glass; the middle layer is the sheet metal support structure; and the bottom layer is the inner roof panel (referred to as the roof). In addition, the car roof also needs to install some accessories to meet the requirements of electronic control and other functions.

[0004] Taking the roof as an example, the roof is typically installed on the top of the car using a series of fasteners and bolts. The installation process usually involves placing the roof on the roof and aligning it with pre-designed mounting points on the vehicle body, and then using special tools to secure the roof to the roof.

[0005] Traditional car roof mounting methods occupy valuable roof space, limiting design flexibility and leaving limited headroom for the driver. Secondly, traditional mounting methods lead to complex assembly processes, increasing production costs and production cycle time. Moreover, the additional brackets and fasteners relatively increase the weight of the vehicle, affecting efficiency and increasing material costs. Finally, traditional installation methods may also affect the neatness and uniformity of the vehicle's interior appearance.

[0006] Furthermore, other roof accessories, such as the Electronic Control Unit (ECU), are typically not mounted on separate brackets. ECUs are usually installed in specific locations inside the vehicle and often require integration with the roof panel, thus reducing the visible roof area and overhead space.

[0007] Therefore, it is necessary to propose a canopy glass assembly to solve at least one of the above problems. Summary of the Invention

It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims.

[0079] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0080] This invention provides a panoramic glass assembly and vehicle that can increase interior space, reduce the production of unnecessary accessories and reduce installation costs; at the same time, it can reduce vehicle weight, further improve efficiency, and enhance vehicle performance.

[0081] Please refer to the following for comprehensive information. Figures 1 to 8 The embodiments of this application provide a canopy glass assembly, which may include: a canopy glass 1 having opposing inner surfaces 11 and outer surfaces; at least one functional bracket, which is injection molded and fixed to the inner surface 11 of the canopy glass 1, and the functional bracket and the canopy glass 1 form an integrated structure.

[0082] This application provides a novel bracket installation method. Specifically, functional brackets (such as roof brackets and automotive roof electronic control unit (ECU) brackets) are integrated by injection molding and fixedly integrated onto the inner surface 11 of the sunroof glass 1, so that the functional brackets and the sunroof glass 1 form an integrated structure. This increases interior space, reduces the production of unnecessary accessories and parts, and lowers installation costs. At the same time, it can reduce vehicle weight, further improve efficiency, and enhance vehicle performance.

[0083] In some embodiments, the outer edge of the canopy glass 1 is provided with an edge-sealing mechanism 13, and the functional support is fixed to the inner surface 11 of the canopy glass 1 through the edge-sealing mechanism 13.

[0084] The injection molding material used for the edging mechanism 13 may include: polyvinyl chloride (PVC), thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), or polyurethane (PU), etc. Of course, other injection molding materials can also be used for the edging mechanism 13, and this application does not limit it to a single material. In the embodiments of this application, PU is used as an example for illustration; other materials can be adapted to the above-mentioned materials. When the edging mechanism 13 is formed by PU injection molding, the functional support is simultaneously integrated and fixed to the inner surface 11 of the canopy glass 1.

[0085] For the canopy glass 1 equipped with the edge-sealing mechanism 13, it itself needs to be edge-sealed using an injection molding process. In this application, the functional support is directly fixed and integrated onto the canopy glass 1 through injection molding. During the manufacturing process, the functional support is placed inside the canopy mold. Then, the injection molding material fills the mold through the injection molding process, forming an integrated structure.

[0086] This technology ensures a tight connection between the functional bracket and the car sunroof, forming a fully enclosed structure between components. This not only provides excellent sealing, preventing liquids or dust from entering the gaps, but also reduces the number of times components need to be reinstalled, thereby reducing manufacturing costs.

[0087] In some embodiments, the functional bracket may include any one or a combination of the following: a first bracket 2 for mounting the roof, and a second bracket 3 for mounting the ECU.

[0088] Specifically, the functional bracket may include a first bracket 2 for mounting the ceiling, or the functional bracket may include a second bracket 3 for mounting the ECU, or the functional bracket may simultaneously include both the first bracket 2 for mounting the ceiling and the second bracket 3 for mounting the ECU. Furthermore, the specific composition and form of the functional bracket can be adapted to the needs of actual application scenarios and are not limited to the above description. Those skilled in the art, guided by the technical essence of this application, may make other modifications, but as long as the functions and effects achieved are the same as or similar to those of this application, they should all be covered within the scope of protection of this application. In the embodiments and accompanying drawings of this application, the example of the functional bracket including a first bracket 2 for mounting the ceiling and a second bracket 3 for mounting the ECU is mainly used for illustration.

[0089] Please refer to the following: Figure 2 , Figure 4 and Figure 6 In one embodiment, the first support 2 may include a plurality of first supports 2 arranged at predetermined structural intervals adapted to the outer contour of the ceiling.

[0090] In this embodiment, the first bracket 2 can be a ceiling bracket for installing a ceiling. A ceiling is generally a rectangular plate with a certain thickness; however, the outline of the ceiling is not limited to the example described above. This application only uses a rectangle as an example for explanation. The outer edge of the ceiling typically has multiple locking portions spaced apart along its outer contour. The number of first brackets 2 can be multiple, and their number and position can be adapted to the position and number of locking portions of the ceiling. For example, when the outer contour of the ceiling is rectangular, the predetermined structure enclosed by the first brackets 2 can also be rectangular.

[0091] In order to install and position the canopy, the first bracket 2 is provided with a first mating part on the side opposite to the outer edge of the canopy glass 1 for mating with the canopy.

[0092] Specifically, the first bracket 2 and the ceiling can be engaged by a snap-fit ​​connection. The edge of the ceiling is provided with a snap-fit ​​portion, and the first engaging portion is a snap-fit ​​groove 21 adapted to the snap-fit ​​portion. Of course, the specific form of the first engaging portion of the first bracket 2 is not limited to the example above, and it can be adaptively adjusted according to the different structures of the edge of the ceiling.

[0093] like Figure 8 As shown, in one specific embodiment, the snap-fit ​​portion extends longitudinally along a predetermined direction to form a snap-fit ​​strip 4 with a predetermined length L, and the snap-fit ​​groove 21 is a through groove extending longitudinally along the predetermined direction, wherein the length of the snap-fit ​​groove 21 along the predetermined direction is less than the predetermined length L.

[0094] In this embodiment, the snap-fit ​​part of the canopy can be a snap-fit ​​strip 4 extending longitudinally along the extension direction of the canopy frame. The snap-fit ​​strip 4 has a predetermined length L, which is greater than the length of the snap-fit ​​groove 21. When the canopy and the first bracket 2 are fitted together by snap-fit, the snap-fit ​​part on the canopy can be designed with redundancy, that is, the matching predetermined length L is greater than the length of the snap-fit ​​groove 21 of the first bracket 2. When installing the canopy, the client only needs to push it upward in the Z direction, without the need for precise positioning, which facilitates the client's installation.

[0095] Furthermore, the snap-fit ​​portion has a first inclined surface 41 formed on the side facing the inner surface 11 of the skylight glass 1; the snap-fit ​​groove 21 includes an upper stop wall 211 close to the skylight glass 1 and a lower stop wall 212 relatively far away from the skylight glass, and the lower stop wall 212 has a second inclined surface 2121 adapted to the first inclined surface 41 on its lower surface opposite to the upper stop wall 211.

[0096] When the locking part of the canopy has a certain slope, a guide angle adapted to the slope can be provided at the locking groove 21 to facilitate the canopy being locked into the first bracket 2. Specifically, the slope can be a first inclined surface 41 formed on the side of the locking part facing the inner surface 11 of the canopy glass 1; the guide angle can be a second inclined surface 2121 provided on the lower stop wall 212.

[0097] Furthermore, along the depth direction of the locking groove 21, the length of the lower stop wall 212 is less than the length of the upper stop wall 211. In this way, by using the shorter lower stop wall 212 and the longer upper stop wall 211 to cooperate, it is beneficial for the locking part of the roof to be smoothly locked into the locking groove 21 during the roof assembly stage. After the roof assembly is completed, it is beneficial for the locking part of the roof to be reliably limited by the locking groove 21.

[0098] Traditional roof brackets are fixed to the vehicle body sheet metal by magnetic attraction or bolts. The first bracket 2 proposed in this application is different from the traditional roof bracket installation. The first bracket 2 is integrally injection molded and fixed to the sunroof glass 1, eliminating the need to fix it to the sheet metal. The roof can be directly snapped onto the sunroof glass 1, thereby increasing the interior space of the vehicle.

[0099] During installation, the roof can be directly clipped onto the vehicle roof, eliminating the need for additional roof support procedures such as mounting brackets on sheet metal. This facilitates optimization of the vehicle assembly process at the OEM level, improves overall production efficiency, and increases OEM revenue.

[0100] Meanwhile, the first bracket 2 used for installing the roof is integrally injection molded with the skylight glass 1, without the need for fixed connection with sheet metal. The gap between the first bracket 2 and the skylight glass 1 is guaranteed by the mold and is more uniform. Therefore, after the roof is assembled, the gap between it and the skylight glass is more uniform and more aesthetically pleasing.

[0101] In some embodiments, the outer edge of the canopy glass 1 is provided with an edge-sealing mechanism 13, and the first support 2 further includes a first connecting portion 23 connected to the edge-sealing mechanism 13, and a first abutting portion 22 located between the first mating portion and the first connecting portion 23. The first abutting portion 22 can be used to abut against the mold.

[0102] During injection molding, the first connecting part 23 is covered with injection molding material, and the first abutting part 22 can be subjected to abutting force by the mold.

[0103] In this embodiment, the canopy glass 1 has an edge-sealing mechanism 13 on its outer edge. The first support 2 may have a first connecting portion 23 connected to the edge-sealing mechanism 13. The first connecting portion 23 includes a first connecting body, on which at least one first process hole 230 is provided. For example, there may be four first process holes 230, which are spaced apart on the first connecting body. During injection molding, the injection material flows through the first process holes 230, and after injection molding, the PU and the first support 2 are mechanically engaged, thereby strengthening the first support 2.

[0104] The first support 2 also includes a first abutment portion 22 located between the first mating portion and the first connecting portion 23. On the side facing away from the inner surface 11 of the skylight glass 1, the distance between the surface of the first abutment portion 22 and the inner surface 11 of the skylight glass 1 is less than the distance between the first connecting portion 23 and the first mating portion and the inner surface 11 of the skylight glass 1.

[0105] like Figure 4 As shown, a vehicle has relative X, Y, and Z directions in space. The X direction is the forward and backward direction of the vehicle's movement; the Z direction is the vertical direction perpendicular to the X direction; and the Y direction is the horizontal direction perpendicular to both the X and Z directions.

[0106] Specifically, the first abutment portion 22 can be a groove formed between the first mating portion and the first connecting portion 23. During injection molding, in order to limit the first support 2 in the Z direction, an abutment force can be applied to the outside of the first abutment portion 22. Specifically, this abutment force can be formed by the mold abutting against the bottom surface of the groove, and the edge of the groove can also be provided with a stop for stopping the injection molding material. In addition, the surface where the groove is located is a contoured surface, which can ensure accurate X / Y positioning of the first support 2 on the mold.

[0107] Furthermore, along the extending direction of the snap-fit ​​groove 21, the first bracket 2 is also provided with a first positioning hole 25 near the snap-fit ​​groove 21. By providing the first positioning hole 25 on both sides of the first bracket 2, it can be used to assist the first bracket 2 in positioning in the mold and improve the positioning accuracy. The first positioning hole 25 can be a positioning blind hole or a positioning groove provided on both sides of the first bracket 2.

[0108] In one embodiment, the skylight assembly may further include a first sealing support 24, at least a portion of which abuts against the first abutment portion 22 and the inner surface 11 of the skylight 1.

[0109] In this embodiment, a first sealing support 24 is further provided between the first abutment portion 22 and the inner surface 11 of the skylight glass 1. The first sealing support 24 can be made of a compressible material. The thickness H of the first sealing support 24 is greater than the distance from the first abutment portion 22 to the inner surface 11 of the skylight glass 1. The first sealing support 24 abuts against the first abutment portion 22 and the inner surface 11 of the skylight glass 1 in a compressed state. That is, after deforming, the first sealing support 24 is disposed between the first abutment portion 22 and the inner surface 11 of the skylight glass 1 in an interference fit.

[0110] When the first abutment portion 22 and the inner surface 11 of the skylight glass 1 are fitted with the first sealing support 24, during injection molding, the injection molding material can be stopped and limited to prevent it from continuing to flow towards the center area of ​​the skylight glass 1 (preventing overflow). The injection molding material can also protect the skylight glass 1. When an abutment force is applied to the first abutment portion 22, it may cause excessive local stress in the skylight glass 1, leading to cracking. The first sealing support 24 can buffer the force on the skylight glass 1, reducing the local stress on the skylight glass 1. Excessive stress can prevent the canopy glass 1 from cracking. In addition, during injection molding, when the first sealing support 24 is set, the deformation characteristic of the first sealing support 24 is utilized. In the Z direction, the reverse elastic force generated by the first sealing support 24 after being squeezed helps the mold and the first bracket 2 to fit tightly against the first abutment part 22, so that the first bracket 2 and the mold have a minimum fitting gap, that is, ensure that the mold can be pushed into place, thereby ensuring that the first bracket 2 is accurately positioned in the Z direction and has a high positional accuracy.

[0111] Specifically, the first sealing support 24 can be in the form of foam, which can be positioned by adhesive bonding. Of course, the first sealing support 24 can also be in other forms and is not limited to the above description. Those skilled in the art may make other modifications based on the technical essence of this application, but as long as the function and effect achieved are the same as or similar to those of this application, they should be covered within the scope of protection of this application.

[0112] Taking foam as an example, its edges can be made of sharp corners without chamfering, which can reduce the gap between the foam and the first support 2, and further reduce the occurrence of overflow during injection molding.

[0113] Please refer to the following: Figure 3 , Figure 5 and Figure 7 In one embodiment, the second bracket 3 may include a bracket mounting surface 31, on which a second mating part and a second positioning hole for adapting to the ECU are provided.

[0114] In this embodiment, the second bracket 3 can be a bracket for mounting the ECU. Overall, the principle of the second bracket 3 is similar to that of the first bracket 2 described above, and can be further explained by referring to the specific description of the embodiment of the first bracket 2 described above.

[0115] The ECU itself also has predetermined assembly requirements. In order to meet the assembly requirements of the ECU, the second bracket 3 has a second mating part and a second positioning hole on its bracket mounting surface 31 for adapting to the ECU.

[0116] The second mating part may include a combination of several elongated fixing slots 311 and square slots 312.

[0117] Specifically, the second bracket 3 placed on the canopy glass 1 can be a structure with a flange and a large bracket mounting surface 31. In one specific embodiment, the bracket mounting surface 31 can be provided with six elongated fixing slots 311 and two square slots 312. Along the long side of the second bracket 3, three elongated fixing slots 311 and one square slot 312 can be located on one side, and the other three elongated fixing slots 311 and one square slot 312 can be located on the other side.

[0118] When the vehicle roof electronic control unit (ECU) is assembled onto the second bracket 3 via six elongated fixing slots 311 and two square locking slots 312, the elongated fixing slots 311 first ensure the Y-axis positioning of the ECU, and then the square locking slots engage to ensure the X-axis positioning of the ECU, thereby achieving precise assembly of the ECU and the bracket. Of course, the specific positions and number of the elongated fixing slots and square locking slots 312 can be adapted according to the assembly requirements of the ECU, and this application does not impose a single limitation.

[0119] The second positioning hole may include a circular hole 313 and a waist hole 314 spaced apart. The second positioning hole is used to cooperate with the mold. The second bracket 3 is mainly positioned with the mold through the circular hole 313, and then auxiliaryly positioned through the waist hole 314.

[0120] When the second bracket 3 is integrally injection molded with the skylight glass 1, it can be placed in the stepped groove with a certain depth around the skylight glass 1 to increase the edge bonding strength after injection molding. The large-area groove allows it to be better fixed to the skylight glass 1 after injection molding, providing a foundation with excellent load-bearing capacity.

[0121] In addition, the shell of the second support 3 can be evenly distributed with ribs to reinforce the second support 3 itself and ensure the strength and rigidity of the second support 3.

[0122] In one embodiment, the outer edge of the canopy glass 1 is provided with an edge-sealing mechanism 13, and the outer edge of the bracket mounting surface 31 further includes a second abutting portion 32 and a second connecting portion 33 extending outward in sequence. The second connecting portion 33 is connected to the edge-sealing mechanism 13. The second abutting portion 32 can be used to abut against the mold.

[0123] During injection molding, the second connecting part 33 is covered with injection molding material, and the second abutting part 32 can be subjected to abutting force through the mold.

[0124] In this embodiment, the canopy glass 1 has an edge-sealing mechanism 13 on its outer edge. The outer edge of the mounting surface 31 of the bracket can be formed with a flange structure. Specifically, the flange structure may include a second abutment portion 32 and a second connecting portion 33. The second connecting portion 33 is located at the outermost edge of the second bracket 3, and during injection molding, the second connecting portion 33 is covered with injection molding material.

[0125] The second connecting part 33 is a stepped part formed away from the inner surface 11 of the canopy glass 1. After the integral injection molding is completed, the stepped part and the injection molding material form a stepped structure. This stepped structure can increase the stress between the second support 3 and the injection molding material, thereby ensuring the stable integral structure of the second step and the injection molding material.

[0126] Specifically, on the side facing away from the inner surface 11 of the canopy glass 1, the distance between the surface of the second abutment portion 32 and the inner surface 11 of the canopy glass 1 is less than the distance between the second connecting portion 33 and the bracket mounting surface 31 and the inner surface 11 of the canopy glass 1.

[0127] Specifically, the second abutment portion 32 can be a groove formed between the bracket mounting surface 31 and the second connecting portion 33. During injection molding, an abutment force can be applied to the outside of the second abutment portion 32 to limit the second bracket 3 in the Z direction. Specifically, this abutment force can be formed by the mold abutting against the bottom surface of the groove, and the edge of the groove can also be provided with a stop for stopping the injection molding material. In addition, the grooved structure of the second abutment portion 32 can also be used to increase the edge adhesion after injection molding.

[0128] In one embodiment, the skylight assembly may further include a second sealing support 34, at least a portion of which abuts against the second abutment portion 32 and the inner surface 11 of the skylight 1.

[0129] In this embodiment, the second sealing support 34 functions similarly to the first sealing support 24 described above. The main differences between this second sealing support 34 and the first sealing support 24 lie in their shape, construction, and size. The contour of the second sealing support 34 can be adapted to the outer edge contour of the second bracket 3; for example, it can be a circumferentially closed structure.

[0130] A second sealing support 34 is also provided between the second abutment portion 32 and the inner surface 11 of the skylight glass 1. The second sealing support 34 can be formed of a material with certain compressibility. After the second sealing support 34 deforms, it is disposed between the second abutment portion 32 and the inner surface 11 of the skylight glass 1 in an interference fit manner.

[0131] When the second abutment portion 32 and the inner surface 11 of the skylight glass 1 are fitted with the second sealing support 34, during injection molding, the injection molding material can be stopped and limited to prevent it from continuing to flow towards the center area of ​​the skylight glass 1 (preventing overflow). The injection molding material can also protect the skylight glass 1. When an abutment force is applied to the second abutment portion 32, it may cause excessive local stress in the skylight glass 1, leading to cracking. The second sealing support 34 can buffer the force on the skylight glass 1, reducing the local stress on the skylight glass 1. Excessive stress can prevent the canopy glass 1 from cracking. In addition, during injection molding, when the second sealing support 34 is set, the deformation characteristic of the second sealing support 34 is utilized. In the Z direction, the reverse elastic force generated by the compression of the second sealing support 34 helps the mold and the second bracket 3 to fit tightly against the second abutment part 32. This ensures that there is a minimum fit gap between the second bracket 3 and the mold, that is, it ensures that the mold can be pushed into place. This ensures that the second bracket 3 is accurately positioned in the Z direction and has a high degree of positional accuracy.

[0132] Specifically, the second sealing support 34 can be in the form of foam, which can be positioned by adhesive bonding. Of course, the second sealing support 34 can also be in other forms and is not limited to the above description. Those skilled in the art may make other modifications based on the technical essence of this application, but as long as the function and effect achieved are the same as or similar to those of this application, they should be covered within the scope of protection of this application.

[0133] Traditionally, ECU brackets are bolted to the vehicle's sheet metal. Since the ECU bracket is made of plastic, contact between the plastic and the metal sheet metal poses a risk of future rattling noises. However, by integrally injection molding the second bracket 3 (ECU bracket) onto the sunroof assembly, direct contact between the ECU bracket and the sheet metal is avoided, reducing the risk of rattling noises. Furthermore, with the ECU bracket injection molded onto the sunroof assembly, the ECU does not directly contact the sheet metal after installation, reducing metal interference with antenna signals and potentially enhancing ECU signal propagation for faster information response.

[0134] Moreover, when the ECU bracket is integrally injection molded onto the sunroof, it can save more space than the traditional bolt-on method. In the traditional method, the space between the sunroof and the ECU bracket is idle and cannot be used, while in the integral injection molding method, the idle space is compressed or even eliminated, thereby freeing up interior space.

[0135] In one embodiment, when the functional bracket includes a first bracket 2 for mounting the roof and a second bracket 3 for mounting the ECU, the number of first brackets 2 for mounting the roof is generally multiple, and at least one of the first brackets 2 adjacent to the second bracket 3 is connected to the second bracket 3 through the edge-sealing mechanism 13.

[0136] Specifically, for example, the two first supports 2 near the second support 3 can be fixed to the edge-sealing mechanism 13 via the second support 3. This fixing method can specifically be a one-piece injection molding method. Of course, other fixing methods are also possible; in the embodiments of this application, one-piece injection molding is mainly used as an example for illustration.

[0137] For example, such as Figure 3 As shown, the edging mechanism 13 may include an edging body 130 located at the outer edge of the canopy glass 1. A first sub-edging 131 is formed between the second support 3 and the edging body 130. The second support 3 is connected to the edging body 130 through the first sub-edging 131. A second sub-edging 132 is formed between at least one first support 2 adjacent to the second support 3 and the second support 3. At least one first support 2 adjacent to the second support 3 is connected to the second support 3 through the second sub-edging 132.

[0138] In this embodiment, when the first support 2 and the second support 3 are integrated onto a single skylight glass 1, the first support 2 and the second support 3 adjacent to the second support 3 can be integrally molded through an injection molding channel using an injection molding process. During injection molding, the edge material flows from the edge to the second support 3 and then to the first support 2, thereby saving injection molding material and improving the operability of the injection molding process. In addition, when the second support 3 is integrated with two adjacent first supports 2 through an injection molding channel, it is also beneficial to form a larger area injection molding structure, thereby helping to ensure the reliability of the injection molding structure fixed on the skylight glass 1.

By setting the panoramic glass assembly, the vehicle can achieve the technical effects achieved by the above-mentioned panoramic glass assembly implementation.
