Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts technology, specifically to a sunroof sealing structure and an automobile. Background Technology
[0002] Car sunroofs are typically mounted on the roof of the vehicle. To seal the gap between the sunroof glass and the vehicle body, a sealing strip is usually installed on the outer periphery of the sunroof glass. This sealing strip makes a tight seal with the vehicle body. However, the sealing strips in this technology cannot accommodate the dimensional tolerances of the roof. When the width of the roof is too small, when the vehicle travels over twisting or bumpy roads, the sunroof glass will be subjected to excessive pressure and friction from the road surface, resulting in a squeaking noise that affects the user experience. Utility Model Content
[0003] In view of this, the embodiments of this application aim to provide a sunroof sealing structure and automobile that has both good sealing performance and can reduce abnormal noise.
[0004] To achieve the above objectives, one embodiment of this application provides a sunroof sealing structure, comprising:
[0005] A frame structure having a skylight;
[0006] The skylight glass covering the skylight includes a glass body and a sealing element. The sealing element includes a main body and a sealing part. The sealing part has a first section and a second section formed by bending. A bending angle that can be changed under external force is formed between the first section and the second section. The main body covers the outer periphery of the glass body. The first section is connected to the main body, and the second section is in sealed contact with the frame structure.
[0007] In some implementations, the first segment may rotate relative to the main body.
[0008] In some embodiments, the sealing portion has a transition section located between the first segment and the second segment, the thickness of the transition section being less than the thickness of the first segment and the second segment, and the bending position of the sealing portion being located in the transition section.
[0009] In some embodiments, the sealing portion forms the transition section by providing a stress-reducing groove located between the first and second sections on one side near the bend angle.
[0010] In some embodiments, the sealing portion is in an initial state of separation from the frame structure, and is in an unfolded state without bending.
[0011] In some embodiments, the sunroof sealing structure further includes a sealing ring that surrounds the periphery of the sunroof and makes sealing contact with both the frame structure and the sunroof glass.
[0012] In some implementations, the sealing ring is in sealing contact with the glass body.
[0013] In some embodiments, the frame structure includes a front crossbeam, a top cover outer panel, and two side panels that enclose the sunroof. The front crossbeam and the top cover outer panel are located on the front and rear sides of the sunroof along the vehicle's forward direction, respectively. The two side panels are located on opposite sides of the sunroof along a transverse direction perpendicular to the vehicle's forward direction. The sealing element has at least one sealing portion corresponding to each of the side panels.
[0014] In some embodiments, the seal further has a sealing portion corresponding to the outer plate of the top cover.
[0015] In some embodiments, the side panel includes a first plate body, a first connecting portion, and a first folded edge portion for enclosing the skylight. The first connecting portion is connected to the first plate body and bends inward toward the side panel. The first folded edge portion is located on the side opposite to the first plate body and bends away from the first plate body. The skylight sealing structure also includes a sealing ring surrounding the periphery of the skylight. The sealing ring is in sealing contact with the front crossbeam, the top cover outer plate, the first folded edges of the two side panels, and the skylight glass. The second segment of each sealing element is in sealing contact with the first connecting portion of the corresponding side panel.
[0016] In some embodiments, the outer top cover panel includes a second plate body, a second connecting portion, and a second folded edge portion for enclosing the skylight. The second connecting portion is connected to the second plate body and bends inward toward the side panel. The second folded edge portion is located on the side opposite to the second connecting portion and the second plate body and bends away from the second plate body. The sealing ring is in sealing contact with the second folded edge portion. The sealing element also has a sealing portion corresponding to the outer top cover panel, and the second segment of the sealing portion is in sealing contact with the second connecting portion.
[0017] In some implementations, the seal and the glass body are injection-molded with an edge-wrap structure.
[0018] Another embodiment of this application provides an automobile including the sunroof sealing structure described above.
[0019] This application provides a sunroof sealing structure and an automobile. The sealing element in the sunroof sealing structure includes a main body and a sealing part. The main body covers the outer periphery of the glass body. A first section of the sealing part is connected to the main body, and a second section makes sealing contact with the frame structure, thereby sealing the gap between the glass body and the frame structure. When the second section makes sealing contact with the frame structure, the bending angle between the first and second sections can change according to the distance between the main body and the frame, allowing the sealing element to adapt to the dimensional deviations of the frame structure. This provides both good sealing performance between the sealing element and the frame structure and reduces abnormal noises caused by compression friction. Attached Figure Description

[0027] In the description of the embodiments in this application, it should be noted that the terms "direction of travel" and "lateral direction" are based on the appendix. Figure 2The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.
[0028] This application provides a skylight sealing structure; please refer to [link / reference]. Figures 1 to 6 The sunroof sealing structure includes a frame structure 10 and a sunroof glass 20.
[0029] The frame structure 10 has a skylight 10a, and the skylight glass 20 covers the skylight 10a.
[0030] The skylight glass 20 includes a glass body 21 and a sealing element 22. The sealing element 22 includes a main body 221 and a sealing part 222. The sealing part 222 has a first section 2221 and a second section 2222 formed by bending. A bending angle 222a that can be changed under the action of external force is formed between the first section 2221 and the second section 2222. The main body 221 covers the outer periphery of the glass body 21. The first section 2221 is connected to the main body 221. The second section 2222 is in sealed contact with the frame structure 10.
[0031] The seal 22 is used to seal the gap between the glass body 21 and the frame structure 10.
[0032] The main body 221 covers the outer periphery of the glass body 21, which can improve the connection stability between the main body 221 and the glass body 21. It should be noted that the outer periphery refers to the side area of the edge region of the glass body 21 that can be covered or contacted by the main body 221. That is, the main body 221 covers the edge region of the glass body 21 in a ring shape.
[0033] The position of the main body 221 covering the outer periphery of the glass body 21 is not limited. For example, the main body 221 can cover only one side, that is, only the main body 221 covers the upper side, lower side, or the transition side between the long side and the lower side of the glass body 21 along the thickness direction. The main body 221 can also cover multiple sides; for example, please refer to [reference needed]. Figures 3 to 6 The main body 221 simultaneously covers the lower side and transition side of the edge region of the glass body 21, thereby not only providing good sealing and connection stability between the main body 221 and the glass body 21, but also giving the skylight glass a better aesthetic appearance. In another embodiment, the main body 221 may also simultaneously cover the upper side and transition side, or simultaneously cover the upper side and lower side, or simultaneously cover the upper side, lower side, and transition side.
[0034] The sealing part 222 achieves a seal between the sunroof glass 20 and the frame structure 10 by sealing the second section 2222 with the frame structure 10.
[0035] The formation of the first segment 2221 and the second segment 2222 by bending means that the sealing part 222 bends under the action of external force, thereby forming the first segment 2221 and the second segment 2222. That is to say, the first segment 2221 and the second segment 2222 can rotate relative to each other under the action of external force to form a certain angle, which is the bending angle 222a. It should be noted that the bending of the sealing part 222 is an elastic deformation, thereby allowing the bending angle 222a to be variable. When the external force disappears, that is, when the sealing part 222 separates from the frame structure 10, the sealing part 222 returns to its initial state.
[0036] The initial state of the sealing portion 222 is not limited. For example, the initial state of the sealing portion 222 can be an unfolded state without bending, that is, the first segment 2221 and the second segment 2222 are in the same virtual plane, and the bending angle 222a between the first segment 2221 and the second segment 2222 is 180 degrees. In another embodiment, the initial state of the sealing portion 222 can also be a bent state with a certain bending angle 222a.
[0037] It is understandable that the external force acts as the interaction force between the sealing part 222 and the frame structure 10. When the second segment 2222 makes sealing contact with the frame structure 10, the frame structure 10 can apply a certain compressive force to the sealing part 222, thereby changing the angle 222a between the first segment 2221 and the second segment 2222. For example, the angle 222a depends on the distance between the main body 221 and the frame structure 10. The smaller the distance between the main body 221 and the frame structure 10, the smaller the angle 222a; the larger the distance between the main body 221 and the frame structure 10, the larger the angle 222a.
[0038] Preferably, the second segment 2222 maintains an interference of 1mm-2mm with the frame structure 10. That is, when the sealing part 222 is in the initial state, the second segment 2222 should extend 1mm-2mm beyond the frame structure 10. This ensures that the second segment 2222 can maintain a sealed contact with the frame structure 10 even when there is an upper or lower deviation in the size of the frame structure 10. At the same time, it can also improve the aesthetics of the connection between the sunroof glass 20 and the frame structure 10.
[0039] This application also provides a vehicle including the sunroof sealing structure described in any embodiment of this application.
[0040] The sealing element 22 in the sunroof sealing structure of this application embodiment includes a main body 221 and a sealing part 222. The main body 221 covers the outer periphery of the glass body 21. The first segment 2221 of the sealing part 222 is connected to the main body 221, and the second segment 2222 is in sealing contact with the frame structure 10, thereby sealing the gap between the glass body 21 and the frame structure 10. When the second segment 2222 is in sealing contact with the frame structure 10, the angle 222a of the bending angle between the first segment 2221 and the second segment 2222 can be changed according to the distance between the main body 221 and the frame, so that the sealing element 22 can adapt to the dimensional deviation of the frame structure 10. This not only ensures good sealing between the sealing element 22 and the frame structure 10, but also reduces abnormal noise caused by squeezing friction.
[0041] In some embodiments, the seal 22 and the glass body 21 can be injection-molded with an edge-fitted structure. That is, the seal 22 is integrally injection-molded on the glass body 21, which can improve the production efficiency of the seal 22, reduce production costs, improve the appearance consistency of the sunroof glass 20, and reduce the possibility of sealing failure between the main body 221 and the glass body 21 due to loosening of the seal 22 after long-term use, thereby improving user satisfaction.
[0042] In some embodiments, please refer to Figure 4 The sealing part 222 may have a transition section 2223 located between the first section 2221 and the second section 2222. The thickness of the transition section 2223 is less than the thickness of the first section 2221 and the second section 2222. The bending position of the sealing part 222 is located in the transition section 2223.
[0043] The thickness of the transition section 2223 is less than the thickness of the first section 2221 and the second section 2222, which ensures that when the sealing part 222 bends under external force, its bending position is located between the first section 2221 and the second section 2222, rather than bending on the first section 2221 or the second section 2222.
[0044] For example, please refer to Figure 3 and Figure 4 The sealing part 222 can form a transition section 2223 by providing a force-reducing groove 2223 between the first section 2221 and the second section 2222 on one side near the bending angle 222a.
[0045] It is understood that the bending angle 222a in the embodiments of this application refers to the inner angle formed between the first segment 2221 and the second segment 2222, and the stress-reducing groove 2223 is located on the inner angle side of the sealing part 222, thereby further improving the consistency of the bending position.
[0046] The shape of the stress-reducing groove 2223 is not limited. For example, the stress-reducing groove 2223 can be circular, that is, the groove wall of the stress-reducing groove 2223 is a circular curved surface. More preferably, the diameter of the circular stress-reducing groove 2223 can be 0.5mm-1.0mm.
[0047] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 6 The sunroof sealing structure may also include a sealing ring 30, which surrounds the periphery of the sunroof 10a and is in sealing contact with the frame structure 10 and the sunroof glass 20 respectively.
[0048] The sealing ring 30 is used to seal the sunroof 10a to prevent rainwater or outside air from entering the vehicle body through the sunroof 10a.
[0049] The structure of the sealing ring 30 is not limited; for example, the sealing ring 30 can be a soft adhesive.
[0050] For example, please refer to Figure 3 , Figure 5 and Figure 6 The sealing ring 30 can make sealing contact with the glass body 21. That is, the sealing ring 30 is located between the frame structure 10 and the glass body 21 to improve the sealing performance between the frame structure 10 and the sealing ring 30. More preferably, the sealing ring 30 is located on the lower side of the glass body 21 along the thickness direction to improve the aesthetics of the skylight glass 20. In another embodiment, the sealing ring 30 can also make sealing contact with the sealing element 22.
[0051] In some embodiments, please refer to Figures 1 to 3 , Figure 5 and Figure 6 The frame structure 10 includes a front crossbeam 11, a top cover outer panel 13, and two side panels 12 that enclose the skylight 10a. In other words, the skylight 10a is formed by the front crossbeam 11, the top cover outer panel 13, and the two side panels 12.
[0052] The connection methods of the front crossbeam 11, the outer top cover 13, and the two side panels 12 include, but are not limited to, welding.
[0053] Please see Figures 1 to 6 The front crossbeam 11 and the outer roof panel 13 are located on the front and rear sides of the sunroof 10a along the vehicle's forward direction, respectively. The two side panels 12 are located on opposite sides of the sunroof 10a along the transverse direction perpendicular to the vehicle's forward direction, respectively. The sealing element 22 has at least a sealing part 222 corresponding to the side panel 12. That is, the sealing part 222 is located at least on the side of the main body 221 near the side panel 12 to seal the gap between the glass body 21 and the side panel 12.
[0054] It is understandable that there is a certain production deviation in the distance between the two side panels 12. By making the sealing part 222 in sealing contact with the side panel 12, when the distance between the two side panels 12 changes along the forward direction of the vehicle, the bending angle 222a between the first segment 2221 and the second segment 2222 changes under the action of external force. This allows the sealing part 222 to adapt to the change in the distance between the two side panels 12, thereby avoiding the problem of abnormal noise during vehicle operation caused by the distance between the two side panels 12 being too small, and at the same time avoiding the problem of appearance gaps and poor sealing between the sealing part 222 and the side panel 12 when the distance between the two side panels 12 is too large.
[0055] For example, please refer to Figure 3 The sealing element 22 may also have a sealing portion 222 corresponding to the outer plate of the top cover 13. That is, the main body 221 also has a sealing portion 222 on the side near the outer plate of the top cover 13 to seal the gap between the glass body 21 and the outer plate of the top cover 13.
[0056] For example, please refer to Figure 5 In one embodiment, the seal 22 does not have a sealing portion 222 on the side near the crossbeam. In another embodiment, the seal 22 may also have a sealing portion 222 corresponding to the front crossbeam 11.
[0057] For example, please refer to Figure 3 The side panel 12 may include a first panel portion 121, a first connecting portion 122, and a first folded edge portion 123 for enclosing the skylight 10a. The first connecting portion 122 is connected to the first panel portion 121 and is bent toward the inside of the side panel 12. The first folded edge portion 123 is located on the side opposite to the first connecting portion 122 and the first panel portion 121 and is bent toward the direction away from the first panel portion 121.
[0058] The inner side of the side panel 12 refers to the side of the side panel 12 that is closest to the passenger space of the car.
[0059] It is understandable that the first plate portion 121, the first connecting portion 122 and the first folded edge portion 123 together form a first receiving groove that communicates with the skylight 10a. When the skylight glass 20 is placed over the skylight 10a, part of the structure of the skylight glass 20 is located in the first receiving groove, thereby enabling the skylight sealing structure to have a better flatness and aesthetics.
[0060] Please see Figures 3 to 6The sunroof sealing structure also includes a sealing ring 30 surrounding the sunroof window 10a. The sealing ring 30 is in sealing contact with the front crossbeam 11, the top cover outer panel 13, the first folded edge 123 of the two side panels 12, and the sunroof glass 20. In other words, the sealing ring 30 is located between the first folded edge 123 and the sunroof glass 20, which can improve the sealing performance and aesthetic appearance of the sunroof sealing structure.
[0061] Please continue reading. Figure 3 Since the first connecting part 122 is located on the side of the seal 22 along the transverse direction of the vehicle, the second section 2222 of each seal 22 can respectively make sealing contact with the first connecting part 122 of the corresponding side panel 12, thereby improving the sealing stability between the seal 22 and the side panel 12.
[0062] For example, please refer to Figure 6 The outer panel 13 of the top cover may include a second panel portion 131, a second connecting portion 132, and a second folded edge portion 133 for enclosing the skylight 10a. The second connecting portion 132 is connected to the second panel portion 131 and is bent toward the inside of the side panel 12. The second folded edge portion 133 is located on the side opposite to the second connecting portion 132 and the second panel portion 131 and is bent toward the direction away from the second panel portion 131.
[0063] It is understandable that the second plate portion 131, the second connecting portion 132, and the second folded edge portion 133 together form a second receiving groove that communicates with the skylight 10a. When the skylight glass 20 is placed over the skylight 10a, part of the structure of the skylight glass 20 is located in the second receiving groove, thereby enabling the skylight sealing structure to have a better flatness and aesthetics.
[0064] Please continue reading. Figure 6 The sealing ring 30 can make sealing contact with the second folded edge 133. That is to say, the sealing ring 30 is located between the first folded edge 123 and the sunroof glass 20, which can improve the sealing performance and aesthetic appearance of the sunroof sealing structure.
[0065] Please continue reading. Figure 6 The seal 22 also has a sealing portion 222 corresponding to the outer panel 13 of the top cover. Since the second connecting portion 132 is located on the rear side of the seal 22 along the direction of vehicle travel, the second section 2222 of the sealing portion 222 can make sealing contact with the second connecting portion 132 to improve the sealing stability between the seal 22 and the side panel 12.
