Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a sunroof sealing strip structure and an automobile. Background Technology

[0002] In automotive sunroof systems, the sunroof sealing strip is a core component that ensures the sealing performance between the sunroof and the roof. Its main functions include: preventing rainwater from seeping into the vehicle through the gap between the sunroof and the roof, reducing wind noise generated by airflow through the sunroof gap during vehicle operation, and maintaining the stability of the interior temperature.

[0003] Currently, the conventional automotive sunroof sealing solution in the industry usually involves setting a rubber sealing strip around the edge of the sunroof glass. The sealing strip's elastic deformation forms a tight fit with the sealing strip inside the vehicle body, thereby achieving a basic sealing function.

[0004] However, sunroof sealing strips are mostly made of rubber. As the usage time increases, the rubber material will gradually age and lose elasticity. At this time, relying solely on the elasticity of the sealing strip itself is no longer sufficient to ensure a tight fit with the roof. The sealing gap will further widen, exacerbating problems such as water leakage and wind noise. This not only affects the user experience but may also cause damage to the interior components around the sunroof due to rainwater immersion, shortening the overall lifespan of the sunroof system. Utility Model Content

[0005] Therefore, it is necessary to provide a sunroof sealing strip structure and automobile to address the problem that conventional sunroof sealing strips cannot guarantee a tight fit with the roof after long-term use, resulting in a decrease in sealing performance.

[0008] According to one embodiment of this application, the elastic component further includes: a compression spring sleeved on the piston rod, one end of the compression spring abutting against the pressure cylinder, and the other end abutting against the support member.

[0009] According to one embodiment of this application, the two sides of the extrusion part are respectively connected to the connecting part, and the middle part is bent toward the side away from the connecting part. The support member includes an arc-shaped push rod, which is adapted to the side of the extrusion part near the connecting part and makes contact with it.

[0011] According to one embodiment of this application, each straight edge is provided with a plurality of elastic components, and the plurality of elastic components are spaced apart along the extension direction of the straight edge.

[0012] According to one embodiment of this application, each straight edge is provided with a corresponding support member, the support member located on the straight edge extends along the extension direction of the straight edge, and is connected to a plurality of elastic components on the same straight edge.

[0013] According to one embodiment of this application, the support member located at the arc corner extends in a direction parallel to the arc corner.

[0014] According to one embodiment of this application, the elastic force direction of the elastic component located at the arc corner edge is radial along the arc corner edge.

In this way, together with the elasticity of the compression part itself, the sealing effect is guaranteed. After long-term use, even if the compression part ages and its elasticity decreases, the compression part can still be tightly fitted with the roof under the support of the elastic component and the support member, thereby ensuring the sealing performance after the sunroof is closed and effectively extending the overall service life of the sunroof system.

[0033] Combination Figure 1 and Figure 2 The sunroof sealing strip structure provided in one embodiment of this application includes a sealing strip body 100, a support member 200, and an elastic component 300.

[0034] The sealing strip body 100 includes an mounting portion 111, a pressing portion 112, and a connecting portion 113. The connecting portion 113 is fixedly connected to both the mounting portion 111 and the pressing portion 112, forming an inner cavity. The mounting portion 111 has a groove on the side opposite to the connecting portion 113, which is used to engage with the outer edge of the sunroof glass 400, achieving connection with the sunroof glass 400. The mounting portion 111 can also adopt other structural forms, as long as it can achieve connection with the sunroof glass 400, it is within the scope of protection of this application. When the sunroof is closed, the pressing portion 112 contacts the inner sealing ring or other structures on the roof and undergoes elastic deformation to achieve a seal.

[0035] The support member 200 is located in the inner cavity and abuts against the extrusion part 112. The support member 200 is connected to the extrusion part 112 at the side wall of the inner cavity away from the connecting part 113. The support member 200 can provide support for the extrusion part 112, and when the extrusion part 112 deforms, the support member 200 can move along with the extrusion part 112.

[0036] The elastic component 300 has a fixed end and a movable end. The fixed end is fixedly connected to the connecting part 113, and the movable end is located in the inner cavity and fixedly connected to the support member 200. The elastic component 300 is configured to provide elastic force to the support member 200 in a direction away from the mounting part 111.

[0037] In this embodiment, the sealing strip body 100 can move synchronously with the sunroof glass 400. When the sunroof is open, the sealing strip body 100 separates from the roof or the roof sealing ring and other structures, and the compression part 112 and the elastic component 300 are in a naturally extended state. When the sunroof is closed, the sealing strip body 100 contacts the roof or the roof sealing ring and other structures, and the compression part 112 is compressed, generating elastic deformation in the direction close to the connecting part 113. At the same time, the compression part 112 compresses the elastic component 300 through the support member 200, causing the elastic component 300 to generate elastic deformation. At this time, the reaction force applied by the elastic component 300 to the compression part 112 through the support member 200 can ensure that the compression part 112 and the roof or the roof sealing ring and other structures remain in close contact, thereby ensuring the sealing effect. Even if the extrusion part 112 ages and loses elasticity after prolonged use, the elastic component 300 and the support member 200 can still ensure a tight fit between the extrusion part 112 and the roof, thereby guaranteeing the sealing performance of the sunroof after it is closed and effectively extending the overall service life of the sunroof system.

[0038] In some embodiments, the elastic component 300 includes a pneumatic spring 310, which includes a pressure cylinder and a piston rod. The pressure cylinder is fixedly connected to the connecting portion 113, and the piston rod is slidably connected to the pressure cylinder and fixedly connected to the support member 200.

[0039] In this embodiment, the pressure cylinder of the gas spring 310 is fixedly connected to the connecting part 113 of the sealing strip body 100, ensuring that the pressure cylinder is stably positioned within the inner cavity of the sealing strip body 100 and will not shift with the opening and closing of the sunroof. One end of the piston rod of the gas spring 310 can slide into the inside of the pressure cylinder, while the other end is fixedly connected to the support member 200, allowing the piston rod and the support member 200 to move synchronously. When the sunroof is closed, the pressing part 112 of the sealing strip body 100 is compressed by the inner sealing ring of the roof, and deforms towards the connecting part 113. At this time, the pressing part 112 pushes the support member 200 to move towards the pressure cylinder. The support member 200 then drives the piston rod to compress the air inside the pressure cylinder, so that the air spring 310 is in a compressed state. When the sunroof is opened, the external pressure on the pressing part 112 disappears, and the compressed air inside the pressure cylinder pushes the piston rod to extend outward. The piston rod drives the support member 200 to reset, and the support member 200 further pushes the pressing part 112 back to its natural extended state.

[0040] The gas spring 310 utilizes the compression and expansion characteristics of its internal air to provide continuous and stable elastic force to the support member 200. This elastic force is transmitted through the support member 200 to the compression part 112, ensuring that the compression part 112 maintains tight contact with the inner sealing ring of the roof when the sunroof is closed, effectively preventing sealing gaps caused by insufficient elasticity of the compression part 112 itself. Simultaneously, the elastic force of the gas spring 310 is linearly stable, adapting to the deformation requirements of the compression part 112 under different compression levels. It prevents excessive deformation of the compression part 112 due to excessive compression force, and also ensures sufficient sealing pressure due to insufficient compression force, thereby guaranteeing the consistency and reliability of the sealing effect.

[0041] For example, the pressure cylinder of the gas spring 310 is injection molded as an insert in the connecting portion 113 of the sealing strip body 100. Alternatively, two elastic buckles are symmetrically arranged axially on the outer circumferential surface of the pressure cylinder of the gas spring 310. Each elastic buckle extends outward from the outer surface of the pressure cylinder, and the free end of the buckle is provided with a wedge-shaped locking head facing the end of the pressure cylinder. On the inner wall of the connecting portion 113 of the sealing strip body 100, a rectangular slot adapted to the buckle structure is formed corresponding to the position of the pressure cylinder buckle. The depth of the slot matches the length of the buckle locking head. The pressure cylinder and the connecting portion 113 are connected by the cooperation of the buckle and the slot. Alternatively, the connecting portion 113 is provided with a mounting groove, the pressure cylinder is inserted into the mounting groove, and is bonded and fixed to the connecting portion 113.

[0042] For example, the piston rod end of the gas spring 310 is provided with an annular locking protrusion, which protrudes along the outer circumference of the piston rod and has a trapezoidal cross-section. A circular fitting hole, adapted to the piston rod end, is provided on the support member 200 at a position corresponding to the gas spring 310. An annular groove matching the annular locking protrusion is provided on the inner wall of the fitting hole. The depth of the annular groove is the same as that of the annular locking protrusion. The annular locking protrusion engages with the support member 200 through the annular groove. The edge of the annular groove is rounded to facilitate assembly. During assembly, the piston rod end is aligned with the fitting hole of the support member 200, and an axial thrust is applied to cause the annular locking protrusion to press against the edge of the fitting hole and slide into the annular groove, achieving a locking and fixing between the two. After locking, the piston rod end fits tightly against the inner wall of the fitting hole, with no radial wobble space. Alternatively, the piston rod end of the gas spring 310 is provided with a threaded connecting hole, and the corresponding position of the support 200 is provided with a through mounting hole. The diameter of the mounting hole is the same as the diameter of the bolt rod, and a circular countersunk is provided at the edge of the mounting hole, the depth of which is the same as the thickness of the bolt head. During assembly, the bolt is passed through the mounting hole of the support 200 and screwed into the threaded hole at the end of the piston rod until the bolt head is completely embedded in the countersunk of the support 200, and the bolt rod is tightly fitted with the mounting hole and the threaded hole without any looseness or gap.

[0043] It is worth noting that the connection methods between the pressure cylinder and the connecting part 113 and the connection methods between the piston rod and the support member 200 are only a few of the many connection methods available. Other connection methods that can achieve the connection should also be within the protection scope of the embodiments of this application.

[0044] In some embodiments, the elastic component 300 further includes a compression spring 320 sleeved on the piston rod, with one end of the compression spring 320 abutting against the pressure cylinder and the other end abutting against the support member 200.

[0045] In this embodiment, the compression spring 320 is sleeved on the outside of the piston rod of the pneumatic spring 310. One end of the compression spring 320 abuts against the pressure cylinder end face of the pneumatic spring 310, and the other end abuts against the end face of the support member 200, so that the compression spring 320 can maintain a stable force state between the pressure cylinder and the support member 200. When the skylight is closed, the support member 200 moves towards the pressure cylinder, which simultaneously compresses the piston rod of the compression spring 320 and the pneumatic spring 310. The compression spring 320 then undergoes elastic deformation and stores elastic potential energy. When the skylight is opened, the air inside the pneumatic spring 310 pushes the piston rod to reset, and the elastic potential energy stored in the compression spring 320 is also released, jointly pushing the support member 200 and the compression part 112 back to their natural state. The two always maintain a state of coordinated operation throughout the entire movement.

[0046] The compression spring 320 and the gas spring 310 form a dual elastic support structure, which further enhances the overall elastic stability and reliability of the elastic component 300. When the gas spring 310 experiences elasticity decay due to long-term use, the compression spring 320 can compensate for the insufficient elasticity of the gas spring 310, ensuring that the support component 200 still receives sufficient thrust to push the compression part 112 to achieve sealing. At the same time, the compression spring 320 can also buffer the impact force during the piston rod sliding process, avoiding wear between the piston rod and the pressure cylinder due to excessive instantaneous force, and extending the service life of the gas spring 310. The dual elastic structure design effectively reduces the risk of decreased sealing performance due to the failure of a single elastic component, further improving the durability and sealing effect of the sunroof sealing strip structure.

[0047] In some embodiments, the two sides of the extrusion portion 112 are respectively connected to the connecting portion 113, and the middle portion is bent toward the side away from the connecting portion 113. The support member 200 includes an arc-shaped push rod, which is adapted to the side of the extrusion portion 112 near the connecting portion 113 and is in contact with it.

[0048] In this embodiment, the upper and lower edges of the pressing portion 112 of the sealing strip body 100 are fixedly connected to the upper and lower edges of the connecting portion 113, respectively. The central region of the pressing portion 112 is curved away from the connecting portion 113, forming an arc-shaped contact surface that can adapt to the inner sealing ring of the roof. The support member 200 adopts an arc-shaped push rod structure. The curvature of the arc-shaped push rod is perfectly matched with the inner curvature of the pressing portion 112 near the connecting portion 113. In other words, the support member 200 gradually bends away from the connecting portion 113 from the upper and lower sides to the middle of the support member 200. This allows the arc-shaped push rod to achieve full contact with the inner side of the pressing portion 112 without any gap between them. When the skylight is closed and the compression part 112 deforms, the inner side of the compression part 112 will remain in contact with the arc-shaped push rod, and the deformation force of the compression part 112 can be evenly transmitted to the arc-shaped push rod, which will move synchronously with the deformation direction of the compression part 112; when the skylight is opened and the compression part 112 is reset, the arc-shaped push rod will also return to its initial position along with the compression part 112.

[0049] The matching design of the arc-shaped push rod and the inner side of the extrusion part 112 ensures that all parts of the extrusion part 112 are supported by the arc-shaped push rod during the deformation process, preventing excessive deformation or damage to the extrusion part 112 due to excessive local stress, effectively protecting the structural integrity of the extrusion part 112 and extending its service life. At the same time, the full contact fit of the arc-shaped push rod can evenly transmit the elastic force of the elastic component 300 to all areas of the extrusion part 112, so that the extrusion part 112 can evenly contact the inner sealing ring of the roof, avoiding local loose contact of the extrusion part 112, further improving the overall sealing effect of the sealing strip, and reducing water leakage and wind noise problems caused by local loose sealing.

[0050] Combination Figure 3 , Figure 4 and Figure 5 In some embodiments, the sealing strip body 100 has multiple arc-shaped edges 120 and multiple straight edges 110, with adjacent straight edges 110 connected by arc-shaped edges 120, and each arc-shaped edge 120 and each straight edge 110 is provided with a support member 200 and an elastic component 300.

[0051] In this embodiment, the sealing strip body 100 has an overall annular structure, including multiple straight edges 110 and multiple curved edges 120. The ends of two adjacent straight edges 110 are smoothly connected by a curved edge 120 to form a complete annular frame to adapt to the edge shape of the sunroof glass 400. Each of the multiple straight edges 110 and multiple curved edges 120 is configured to include a mounting part 111, a pressing part 112, and a connecting part 113. In the inner cavity of each straight edge 110 and the inner cavity of each curved edge 120, a support member 200 and an elastic component 300 adapted to the structure of the straight edge 110 are provided. The support member 200 and the elastic component 300 of the curved edge 120 work independently from the support member 200 and the elastic component 300 of the straight edge 110, without interfering with each other, and together cover the entire annular area of ​​the sealing strip body 100.

[0052] By providing support members 200 and elastic components 300 on both the straight edge 110 and the curved edge 120 of the sealing strip body 100, sufficient sealing support capacity can be ensured throughout the entire annular area of ​​the sealing strip body 100. This avoids situations where the straight edge 110 seals well but the curved edge 120 fails to seal, completely eliminating sealing blind spots. Especially in the structurally unique area of ​​the curved edge 120, the dedicated support member 200 and elastic component 300 can adapt to the bending shape of the curved edge 120, ensuring that the compression part 112 of the curved edge 120 can also make tight contact with the inner sealing ring of the roof. This effectively solves the problem of sealing gaps that easily occur at corners in conventional sealing strips, further improving the overall sealing performance of the sunroof and protecting the interior environment from the effects of rain and wind noise.

[0053] In some embodiments, each straight edge 110 is provided with a plurality of elastic components 300, and the plurality of elastic components 300 are spaced apart along the extension direction of the straight edge 110.

[0054] In the inner cavity of each straight edge 110 of the sealing strip body 100, multiple elastic components 300 are evenly spaced along the extending direction of the straight edge 110. The multiple elastic components 300 have the same structural specifications, and the fixed end of each elastic component 300 is fixedly connected to the connecting part 113 of the straight edge 110, and the movable end is fixedly connected to the support member 200 of the straight edge 110. When the skylight is closed, the multiple elastic components 300 will be simultaneously squeezed by the support member 200 and generate elastic force, jointly applying a thrust to the support member 200; when the skylight is opened, the multiple elastic components 300 will also reset simultaneously.

[0055] Optionally, the spacing between two adjacent elastic components 300 is kept uniform to ensure that the distribution density of multiple elastic components 300 on the straight edge 110 is consistent, so as to form a continuous elastic support area from one end of the straight edge 110 to the other end.

[0056] Multiple spaced elastic components 300 provide uniform and comprehensive elastic support for the straight edge 110, preventing insufficient elasticity at the ends or middle of the straight edge 110 due to its long length and the inability of a single elastic component 300 to cover the entire edge. The uniformly distributed elasticity ensures that the pressing part 112 of the straight edge 110 receives stable thrust from one end to the other, maintaining uniform contact between the pressing part 112 and the inner sealing ring of the roof, preventing localized loose or tight contact and effectively improving the sealing uniformity of the straight edge 110. Furthermore, the multiple elastic components 300 also provide redundancy; even if one elastic component 300 fails, the remaining elastic components 300 can still maintain the basic sealing effect of the straight edge 110, reducing the risk of seal failure.

[0057] In some embodiments, each straight edge 110 is provided with a support member 200. The support member 200 located on the straight edge 110 extends along the extension direction of the straight edge 110 and is connected to a plurality of elastic components 300 on the same straight edge 110.

[0058] In the inner cavity of each straight edge 110 of the sealing strip body 100, only one support member 200 is provided. The length of the support member 200 matches the length of the straight edge 110 and extends continuously along the extension direction of the straight edge 110, covering the entire inner cavity area of ​​the straight edge 110. Multiple elastic components 300 within the straight edge 110 are fixedly connected to the single support member 200, so that the elastic force generated by the multiple elastic components 300 can be concentrated and transmitted to the support member 200. When the support member 200 is subjected to the elastic force of the multiple elastic components 300, it will exert a thrust in the direction of the extrusion part 112, pushing the extrusion part 112 into contact with the inner sealing ring of the roof, and the support member 200 itself will not bend or displace locally due to the force.

[0059] A single support member 200 can integrate the elastic forces of multiple elastic components 300 within the straight edge 110 into a uniform overall thrust, avoiding uneven force distribution on the extrusion section 112 caused by individual forces exerted by multiple elastic components 300. This ensures that the extrusion section 112 of the straight edge 110 can make uniform contact with the sealing mating parts, further improving the sealing effect of the straight edge 110. Furthermore, compared to configuring a support member 200 for each elastic component 300, the design of a single support member 200 significantly simplifies the structure of the inner cavity of the straight edge 110, reduces the number of parts, lowers the manufacturing cost of the sealing strip body 100, facilitates rapid positioning and installation during assembly, improves assembly efficiency, and also provides convenience for subsequent maintenance and repair, reducing maintenance difficulty.

[0060] In some embodiments, the support member 200 located on the arc corner edge 120 extends in a direction parallel to the arc corner edge 120.

[0061] The support member 200 located on the arc-shaped edge 120 of the sealing strip body 100 extends parallel to the arc-shaped edge 120 itself. The bending shape of the support member 200 is completely consistent with the bending shape of the arc-shaped edge 120, allowing it to tightly fit the inner wall of the inner cavity of the arc-shaped edge 120. Both ends of the support member 200 extend to the connection point between the arc-shaped edge 120 and the adjacent straight edge 110, covering the entire inner cavity area of ​​the arc-shaped edge 120. The support member 200 and the inner side of the pressing part 112 of the arc-shaped edge 120 achieve full contact and fit, with no gaps between them. When the skylight is closed, the deformation of the pressing part 112 of the arc-shaped edge 120 causes the support member 200 to move, and the support member 200 evenly transmits the elastic force of the elastic component 300 to all parts of the pressing part 112. When the skylight is opened, the support member 200 returns to its original position along with the pressing part 112.

[0062] The support member 200 extends along the parallel arc-shaped edge 120, adapting to the curved structure of the arc-shaped edge 120 and providing all-around support for the compression portion 112 of the arc-shaped edge 120. This avoids local support gaps caused by the mismatch between the support member 200 and the arc-shaped edge 120. Especially at the apex of the curve of the arc-shaped edge 120, the support member 200 provides sufficient support force, ensuring that the compression portion 112 at this location will not dent or deform under stress. This ensures that the compression portion 112 of the arc-shaped edge 120 can fit tightly with the sealing components at the corner of the roof. This adaptable support effectively improves the sealing reliability of the arc-shaped edge 120, solves the problem of sealing failure caused by insufficient support at corners in conventional sealing strips, and further guarantees the overall sealing performance of the sunroof.

[0063] In some embodiments, the elastic force direction of the elastic component 300 located at the arc corner edge 120 is radial along the arc corner edge 120.

[0064] The elastic component 300 of the arc-shaped edge 120 of the sealing strip body 100 generates an elastic force in the same direction as the radial direction of the arc-shaped edge 120, that is, the elastic force direction points radially outward of the arc-shaped edge 120 (away from the direction of the bending center of the arc-shaped edge 120), which perfectly matches the force direction of the pressing part 112 of the arc-shaped edge 120 that needs to extend outward to achieve a seal. The fixed end of the elastic component 300 is fixed to the connecting part 113 of the arc-shaped edge 120, and the movable end is connected to the support member 200 of the arc-shaped edge 120. When the elastic component 300 releases its elastic force, it pushes the support member 200 to move radially outward along the arc-shaped edge 120. The support member 200 then drives the pressing part 112 of the arc-shaped edge 120 to extend radially outward, so that the pressing part 112 contacts the sealing mating part at the corner of the roof.

[0065] The consistency between the elastic force direction of the elastic component 300 and the radial direction of the arc corner edge 120 ensures that the elastic force acts directly on the sealing direction of the compression part 112, avoiding force loss due to deviation in the elastic force direction. This allows the elastic force generated by the elastic component 300 to be converted into contact pressure between the compression part 112 and the sealing mating component to the maximum extent, improving the sealing tightness of the arc corner edge 120. Simultaneously, this elastic force direction can adapt to the structural shape of the roof corner, ensuring that the compression part 112 accurately fits the sealing surface at the corner, preventing the compression part 112 from shifting due to incorrect elastic force direction. This effectively eliminates the gap between the arc corner edge 120 and the sealing mating component, further reducing water leakage and wind noise at the sunroof corner and improving the user experience.

[0066] This application embodiment also provides an automobile, including a sunroof glass 400 and the sunroof sealing strip structure described above. The sealing strip body 100 of the sunroof sealing strip structure is arranged around the outside of the sunroof glass 400, and the mounting part 111 of the sealing strip body 100 is fixedly connected to the edge of the sunroof glass 400.

[0067] Optionally, the automobile also includes a passenger compartment, the top of which forms a roof. The roof is provided with a sunroof window, and the sunroof window is provided with an annular inner sealing ring. When the sunroof is closed, the pressing part 112 of the sealing strip body 100 abuts against the inner sealing ring.
