Description

Technical Field

[0001] This application relates to the field of automotive parts, and more particularly to an automotive sunroof sealing ring and its usage method. Background Technology

[0002] Car sunroofs include closed and openable types. Because openable sunroofs need to be opened and closed, the sealing ring cannot be too tightly fitted to the sunroof when it is opened, otherwise the resistance to opening the sunroof will be too high. However, if the contact is not tight, water leakage can easily occur when the sunroof is not needed in rainy weather. Some vehicles have drainage channels inside the vehicle to deal with the leakage problem, but the drainage channel design is complicated, the water flow is small, and it is easy to get clogged after long-term use. On the other hand, water can easily accumulate in the drainage channel, and when the vehicle is driving on a bumpy road, the water in the drainage channel may splash into the car, resulting in a poor user experience. In other words, it is difficult to guarantee the sealing performance of the existing sealing ring when it is suitable for the resistance of opening the sunroof.

[0003] Chinese patent number "CN103909810A" entitled "An Air Pressure Sealing System for an Automobile Sunroof" discloses a sealing system for an automobile sunroof. It involves filling a sealing ring with compressed air via an air filling and releasing device, causing the sealing ring to expand and creating an interference fit between the sealing parts of the sunroof; or releasing the compressed air from the sealing ring via the same device, causing the sealing ring to contract and creating a clearance fit between the sealing parts of the sunroof. This design minimizes the opening and closing resistance of the sunroof and ensures a reliable seal when the sunroof is closed. However, this design requires an air pump, resulting in a complex structure and high cost.

[0004] Chinese patent number "CN207902133U" entitled "Automotive Sunroof Sealing Ring and Sunroof Frame Sealing Structure" discloses a sealing structure in which the sunroof frame and the sealing ring body are fixed together. Similar to ordinary sealing structures, it is difficult to guarantee the sealing performance of the sealing ring when there is appropriate resistance to opening the sunroof. Summary of the Invention

[0005] This application provides a sunroof sealing ring for automobiles and its usage method, so as to at least solve the problem of balancing sealing performance and resistance in the prior art.

[0006] According to a first aspect of this application, a sunroof sealing ring for automobiles is provided, comprising a first sealing portion, a first connecting portion, an abutting portion, a second connecting portion, and a second sealing portion. The second sealing portion is connected to the upper end and / or lower end of the abutting portion via the second connecting portion, and the first sealing portion is connected to the upper end and / or lower end of the abutting portion via the second connecting portion, or the first connecting portion and the second connecting portion are directly connected. The abutting portion is located between the first sealing portion and the second sealing portion, and the abutting portion is movable or rotated relative to the first sealing portion and the second sealing portion under the action of an external force; thereby enabling...

[0007] When the abutting part moves to the first position, a portion of the abutting part directly abuts or connects with the first sealing part and the second sealing part; when the abutting part moves to the second position, the abutting part does not abut or connect with the first sealing part or the second sealing part.

[0008] Alternatively, when the abutting part rotates to the first position, the distance between the abutting part and the abutting or connecting position of the first sealing part and the second sealing part is the first distance, and when the abutting part rotates to the second position, the distance between the abutting part and the abutting or connecting position of the first sealing part and the second sealing part is the second distance, and the first distance is greater than the second distance.

[0009] Compared with the prior art, the automotive sunroof sealing ring and its method of use in this application have the following advantages:

[0010] When the abutting part is in the first position, it abuts or connects with the first and second sealing parts, providing support and improving their sealing performance. When the abutting part is in the second position, it does not abut or connect with either the first or second sealing part, failing to provide support and resulting in better elasticity. This reduces the effort required to open the sunroof, decreases opening resistance, reduces wear, and extends its lifespan. Furthermore, since the sunroof does not leak, a water channel structure is unnecessary below it, simplifying the structure and saving space, thus reducing overall design costs.

[0011] In one embodiment, the first sealing part is provided with a first sealing groove, which can form a better fixed sealing connection.

[0012] In one embodiment, the second sealing part is provided with an arc-shaped sealing surface, which facilitates relative movement of the contact surfaces and reduces movement resistance.

[0013] In one embodiment, the abutting part includes a first rotating plate, a second rotating plate, a third rotating plate, and a fourth rotating plate. The first, second, third, and fourth rotating plates are elastically connected end-to-end or hinged to form a rhombus shape in cross-section. The first and fourth rotating plates rotate in the same direction, while the first rotating plate rotates in the opposite direction to the second and third rotating plates. This means that one opposite corner of the rhombus moves closer to the other opposite corner, and the distance of the other opposite corner can be controlled by adjusting the distance of one opposite corner. This allows for control of the supporting force of the first and second sealing parts, ensuring airtightness while facilitating window opening.

[0014] In one embodiment, the abutting part includes an abutting section and a connecting section. The width of the abutting section is greater than the width of the connecting section, so that the abutting section can form a larger supporting force, and moving it to the connecting section makes it convenient for the sunroof to be opened.

[0015] In one embodiment, the abutment portion has a spindle-shaped structure, which has low resistance to movement and can form a certain elastic support force.

[0016] In one embodiment, the abutting portion forms a first sealing cavity with the first connecting portion and the first sealing portion, and the abutting portion forms a second sealing cavity with the second connecting portion and the second sealing portion. The first sealing cavity and the second sealing cavity are provided with lubricant. This design can reduce movement resistance.

[0017] According to a second aspect of this application, a method for using a car sunroof sealing ring is provided. When closing the sunroof using the aforementioned sealing ring, first confirm whether the abutment portion is in the second position. If it is not in the second position, move or rotate the abutment portion to the second position. Then, close the sunroof to the position abutting the sealing ring. Finally, move or rotate the abutment portion to the first position to ensure that the abutment portion abuts or connects with the first and second sealing portions. This reduces the resistance when closing the sunroof, and the abutment portion allows for a tighter connection after closing, preventing sunroof leaks.

[0018] In one possible implementation, when opening the sunroof, the abutment part is first moved or rotated from a first position to a second position, and then the sunroof is opened. This reduces resistance when opening the sunroof.

[0019] In one embodiment, the abutting part is provided with a driving structure to drive the abutting part to move or rotate, which facilitates the control of the rotation or movement of the abutting part.

[0037] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] like Figure 1 The diagram shows the installation and usage of a car sunroof sealing ring. The sunroof frame 7 is located outside the sunroof sealing ring, and the sunroof glass 6 is located inside the sunroof sealing ring. In some embodiments, the sunroof sealing ring can be fixed to the sunroof glass 6; in other embodiments, the sunroof glass 6 sealing ring can be fixed to the sunroof frame 7. Different installation methods simply require changing the inner and outer structures of the sunroof sealing ring. Up, down, left, right, front, and back indicate the orientation in this usage state.

[0039] Example 1:

[0040] like Figure 2 and Figure 3 As shown, a car sunroof sealing ring includes a first sealing part 1, a first connecting part 2, an abutting part 3, a second connecting part 4, and a second sealing part 5. The second sealing part 5 is connected to the upper and lower ends of the abutting part 3 through the second connecting part 4. The first sealing part 1 is connected to the upper and lower ends of the abutting part 3 through the second connecting part 4. The abutting part 3 is located between the first sealing part 1 and the second sealing part 5. The abutting part 3 can move relative to the first sealing part 1 and the second sealing part 5 under the action of external force. When the abutting part 3 moves to the first position, a portion of the abutting part 3 directly abuts against the first sealing part 1 and the second sealing part 5. If the first sealing part 1 and the second sealing part 5 are made of a material with good elasticity, they can be directly connected. When the abutting part 3 moves to the second position, the abutting part 3 does not abut against or connect with the first sealing part 1 or the second sealing part 5. The first sealing part 1 and the second sealing part 5 are respectively located on both sides of the abutting part 3.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the first sealing part 1 is provided with a first sealing groove 11. The first sealing groove 11 can be used to install the sunroof glass 6 or the sunroof frame 7. When the first sealing groove 11 is located inside the sealing ring, the sunroof glass 6 can be installed into the first sealing groove 11, that is, the car sunroof sealing ring and the sunroof glass 6 are fixed together. When the first sealing groove 11 is located outside the sealing ring, the car sunroof sealing ring is installed on the sunroof frame 7.

[0042] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the second sealing part 5 has an arc-shaped sealing surface 51. The arc-shaped sealing structure facilitates relative movement with other structures and provides a better sealing effect when in the central position. The sealing ring is usually made of elastic rubber material, which has good elasticity, thus fully utilizing the function of elastic deformation to provide the sealing performance of the sealing ring. The second sealing part 5 can be designed as a hollow structure or a solid structure. The hollow structure has better elasticity than the solid structure, and the solid structure has better support than the hollow structure.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the abutting part 3 includes an abutting section 31 and a connecting section 30. The width of the abutting section 31 is greater than the width of the connecting section 30. To facilitate the movement of the abutting part 3, the abutting part 3 is in the shape of a spindle, that is, the cross section is close to a rhombus shape. However, the upper end can be designed to be shorter and wider, and the lower end can be designed to be narrower, so that the abutting section 31 and the connecting section 30 can be formed.

[0044] like Figure 3 and Figure 4 As shown, in one embodiment, the abutting portion 3, together with the first connecting portion 2 and the first sealing portion 1, forms a first sealing cavity 10. The abutting portion 3, together with the second connecting portion 4 and the second sealing portion 5, forms a second sealing cavity 50. Lubricants are provided in both the first sealing cavity 10 and the second sealing cavity 50. The first connecting portion 2 includes a first upper connecting portion 21 and a first lower connecting portion 22. The abutting portion 3, the first sealing portion 1, the first upper connecting portion 21, and the first lower connecting portion 22 form an annular structure. The first upper connecting portion 21 and the first lower connecting portion 22 are made of elastic material, allowing the abutting portion 3 to move up and down without affecting the position of the first sealing portion 1. The second connecting portion 4 includes a second upper connecting portion 23 and a second lower connecting portion 24. The abutting portion 3, the second sealing portion 5, the second upper connecting portion 23, and the second lower connecting portion 24 form an annular structure. The second upper connecting portion 23 and the second lower connecting portion 24 are made of elastic material, allowing the abutting portion 3 to move up and down without substantially affecting the position of the second sealing portion 5. If the first connecting part 2 and the second connecting part 4 have high strength, only the first upper connecting part 21 and the second upper connecting part 23 or only the first lower connecting part 22 and the second lower connecting part 24 can be provided.

[0045] like Figure 3 and Figure 4 As shown, in one embodiment, the first sealing part 1 is provided with a first protrusion 12, the first protrusion 12 is provided with a first groove 13, when the abutting part 3 is in the first position, one side of the abutting section 31 abuts against the first protrusion 12, and the other side abuts against the second sealing part 5. The first groove 13 has the function of restricting the position of the abutting part 3. The first protrusion 12 or the abutting part 3 is made of an elastic material that can deform within a certain range.

[0046] like Figure 5 and Figure 6 As shown, in one embodiment, the abutment part 3 is in the second position, disengaging from the first protrusion 12. The supporting force of the abutment part 3 on the first sealing part 1 and the second sealing part 5 is reduced, resulting in lower resistance to opening the sunroof. Furthermore, to facilitate movement of the abutment part 3, a moving rod 94 is provided. The movement of the abutment part 3 can be controlled by the driving component driving the moving rod 94.

[0047] Example 2:

[0048] like Figure 7 As shown, a car sunroof sealing ring includes a first sealing part 1, a first connecting part 2, an abutting part 3, a second connecting part 4, and a second sealing part 5. The second sealing part 5 is connected to the upper and lower ends of the abutting part 3 through the second connecting part 4. The first sealing part 1 is connected to the upper and lower ends of the abutting part 3 through the second connecting part 4. The abutting part 3 is located between the first sealing part 1 and the second sealing part 5. The abutting part 3 can rotate relative to the first sealing part 1 and the second sealing part 5 under the action of external force. When the abutting part 3 rotates to the first position, the distance between the abutting part 3 and the abutting or connecting position of the first sealing part 1 and the second sealing part 5 is the first distance. When the abutting part 3 rotates to the second position, the distance between the abutting part 3 and the abutting or connecting position of the first sealing part 1 and the second sealing part 5 is the second distance. The first distance is greater than the second distance. The abutting part 3 includes a first rotating piece 32, a second rotating piece 33, a third rotating piece 34, and a fourth rotating piece 35. The first rotating piece 32, the second rotating piece 33, the third rotating piece 34, and the fourth rotating piece 35 are rigidly connected end-to-end or hinged so that the cross-section is rhomboid. This makes the first rotating piece 32 and the fourth rotating piece 35 rotate in the same direction, and the first rotating piece 32 rotates in the opposite direction to the second rotating piece 33 and the third rotating piece 34. The length of the first rotating piece 32 is greater than the length of the third rotating piece 34, and the length of the second rotating piece 33 is greater than the length of the fourth rotating piece 35. In this way, the displacement of the second sealing part 5 corresponding to the abutting part 3 is greater and the supporting force is greater.

[0049] The material of the abutment part 3 is different from that of the connecting part. The first connecting part 2 and the second connecting part 4 are both made of elastic rubber, while the abutment part 3 is made of a more rigid material. The third rotating plate 34 and the fourth rotating plate 35 are connected to the second sealing part 5. The second sealing part 5 is made of elastic rubber material and does not affect the rotation of the third rotating plate 34 and the fourth rotating plate 35.

[0050] like Figure 8 and Figure 9As shown, the upper end of the abutment part 3 is provided with an upper baffle 8, the upper end of which is designed as an arc surface to reduce wind resistance. The lower end of the abutment part 3 is provided with a lower baffle 9, which is designed as a planar structure. By adjusting the distance between the upper baffle 8 and the lower baffle 9, the lateral width of the abutment part 3 can be controlled. That is, when the distance between the upper baffle 8 and the lower baffle 9 decreases, the upper ends of the first rotating plate 32 and the third rotating plate 34 move downward and the lower ends move to both sides when they rotate. Similarly, the lower ends of the second rotating plate 33 and the fourth rotating plate 35 move upward and the upper ends move to both sides. This can form a strong support for the first sealing part 1 and the second sealing part 5, ensuring sealing performance. When the distance between the upper baffle 8 and the lower baffle 9 increases, the first rotating plate 32, the second rotating plate 33, the third rotating plate 34 and the fourth rotating plate 35 rotate in opposite directions, which reduces the support force and facilitates the opening of the sunroof.

[0051] like Figure 8 and Figure 9 As shown, the upper baffle 8 is provided with a screw 90, and the lower baffle 9 is provided with a limiting wheel 91 below it. The limiting wheel 91 is provided with a threaded hole that matches the screw 90. By rotating the limiting wheel 91, the distance between the upper baffle 8 and the lower baffle 9 can be controlled. The limiting wheel 91 is provided with an input part 92 and an output part 93. Since the upper baffle 8 is relatively long, multiple limiting wheels 91 need to be set to simultaneously control the distance between the upper baffle 8 and the lower baffle 9. Setting multiple drive structures is costly. Therefore, adjacent limiting wheels 91 are linked together, so that power can be transmitted to each limiting wheel 91. That is, the output part 93 of one limiting wheel 91 is connected to the input part 92 of the adjacent limiting wheel 91 to achieve transmission. For example, by belt transmission, two limiting wheels 91 can be connected by a belt. In addition, the limiting wheel 91 can also be designed as a sprocket, gear, winch, etc., to transmit power through different transmission methods. This can reduce the number of drive structures and reduce drive costs.

[0052] Example 3:

[0053] like Figure 10As shown, the first rotating piece 32 has a first support piece 36, the second rotating piece 33 has a second support piece 37, the third rotating piece 34 has a third support piece 38, and the fourth rotating piece 35 has a fourth support piece 39. The first rotating piece 32, second rotating piece 33, third rotating piece 34, and fourth rotating piece 35 are manufactured using a rubber-coating process. Specifically, the first support piece 36, second support piece 37, third support piece 38, and fourth support piece 39 are manufactured first, and then rubber material is coated onto the outside or one side of each support piece. The first support piece 36, second support piece 37, third support piece 38, and fourth support piece 39 need to be made of materials with good rigidity and a certain degree of toughness, such as PE, PC, and PVC. The abutting part 3 can be manufactured separately and then placed inside the sealing ring, or it can be integrally molded with the sealing ring. The integral molding process is more complex but has higher production efficiency. Because the sealing ring is relatively wide, it can be manufactured in sections and then heat-fused to form a ring structure. The curved part can be manufactured separately.

[0054] Example 4:

[0055] like Figure 11 As shown, in one embodiment, the sunroof sealing ring is made of transparent silicone rubber. A fourth cavity 40 is provided between the second lower connecting part 24 and the fourth rotating piece 35. Granular hydrogel 41 is placed in the fourth cavity 40. A water-guiding rubber strip 43 is provided on the side of the second lower connecting part 24. The water-guiding rubber strip 43 is provided with water-guiding holes that communicate with the fourth cavity 40. In this way, when the second sealing part 5 leaks locally, the water can be guided to the fourth cavity 40 through the water-guiding rubber strip 43. The hydrogel 41 expands when it comes into contact with water, which makes the sealing performance of the second sealing part 5 better. In order to ensure that the water absorption can be evenly diffused, water-absorbing fiber material 42 is mixed between the granular hydrogel 41. Using plant fiber materials such as cotton has a shorter service life. The fourth cavity 40 has an opening to replace the hydrogel 41. The four corners of the sunroof are usually prone to water leakage. The four corners can also be manufactured separately to form four independent fourth cavities 40. The hydrogel 41 is placed in the fourth cavity 40. The four corners and four sides are formed by heat fusion to form the sunroof sealing ring.

[0056] Example 5:

[0057] like Figure 12As shown, the first connecting part 2 is directly connected to the second connecting part 4; the abutting part 3 adopts a completely independent structural design, that is, after the abutting part 3 is manufactured, it can be inserted into the area between the first connecting part 2 and the second connecting part 4. The length of the first rotating piece 32 is greater than the length of the third rotating piece 34, and the length of the second rotating piece 33 is greater than the length of the fourth rotating piece 35. The abutting part 3 can be rotated by the screw 90 and the limiting wheel 91. The first rotating piece 32 and the second rotating piece 33 are elastically connected and can be reset by the elastic force.

[0058] Example 6:

[0059] like Figure 13 As shown, the abutment part 3 includes a first rotating piece 32 and a third rotating piece 34. The upper ends of the first rotating piece 32 and the third rotating piece 34 are elastically connected or hinged, such that the first rotating piece 32 and the third rotating piece 34 rotate in opposite directions. The lower end of the first rotating piece 32 is limited by the first connecting part 2, and the lower end of the third rotating piece 34 is limited by the second connecting part 4. The first connecting part 2 and the second connecting part 4 are made of elastic material. The abutment part 3 can be controlled to rotate by the screw 90 and the limiting wheel 91. When the upper ends of the first rotating piece 32 and the third rotating piece 34 move downward, their left and right ends move outward to provide greater support force. Figure 14 As shown, after the screw 90 moves downward, the distance between the first sealing part 1 and the second sealing part 5 increases, and the supporting force of the abutment part 3 also increases.

[0060] Example 7:

[0061] like Figure 1-10 As shown, a method for using a car sunroof sealing ring is described. Using the sunroof sealing ring in the above embodiment, when closing the sunroof, first confirm whether the abutment part 3 is in the second position. If it is not in the second position, move or rotate the abutment part 3 to the second position. Then, close the sunroof to the position abutting the sealing ring. Finally, move or rotate the abutment part 3 to the first position to ensure that the abutment part 3 abuts or connects with the first sealing part 1 and the second sealing part 5. Moving the abutment part 3 can change the supporting force on the first sealing part 1 and the second sealing part 5, thereby improving sealing performance or reducing sunroof opening resistance.

[0062] In one embodiment, when performing the sunroof opening operation, the abutment part 3 is first moved or rotated from the first position to the second position, and then the sunroof is opened.

[0063] In one embodiment, the abutment portion 3 is provided with a driving structure to drive the abutment portion 3 to move or rotate. The driving structure can be a linear motion driving structure or a rotational driving structure; some embodiments require linear movement, and some embodiments require rotation.
