Description

Technical Field

[0001] The present application relates to the field of automobile parts, and in particular to an automobile sunroof sealing ring and a method of using the same. Background Art

[0002] Car sunroofs include closed and open types. Open sunroofs need to be opened and closed, so the contact between the sealing ring and the sunroof cannot be too tight when opening the sunroof, otherwise the resistance to opening the sunroof will be large. However, when the sunroof does not need to be opened on rainy days, if the contact is not tight, it is easy to leak. Some vehicles will have drainage grooves inside the vehicle to deal with the leakage problem, but the drainage grooves are complex in design and have a small water flow. They are easily blocked after long-term use. On the other hand, the drainage grooves are prone to water accumulation. When the vehicle is driving bumpy, the water in the drainage grooves may splash into the car, resulting in a poor user experience. That is, it is difficult to ensure the sealing performance of the sealing ring when the existing sealing ring has suitable resistance to opening the sunroof.

[0003] The Chinese patent number "CN103909810A" and the patent name "A car sunroof air pressure sealing system" discloses a sealing system for a car sunroof. Compressed air is filled into the sealing ring through an air charging and discharging device to expand the sealing ring and make the sealing mating part of the car sunroof have an interference fit; or the compressed air in the sealing ring is discharged through the air charging and discharging device to shrink the sealing ring and make the sealing mating part of the car sunroof have a clearance fit; thereby, the opening and closing resistance of the car sunroof when opening or closing is very small, and the sealing is reliable after the car sunroof is closed. However, this design requires the use of an air pump with a complex structure and high cost.

[0004] The Chinese patent number "CN207902133U" and the patent name "Automobile sunroof sealing ring and sunroof frame sealing structure" discloses a sealing structure, in which the sunroof frame is fixed together with the sealing ring body. Like the ordinary sealing structure, it is also difficult to ensure the sealing performance of the sealing ring when there is appropriate resistance to opening the sunroof. Summary of the invention

[0005] The present application provides a car sunroof sealing ring and a method of using the same, so as to at least solve the sealing and resistance balance problems existing in the prior art.

[0006] According to a first aspect of the present application, a car sunroof sealing ring is provided, comprising a first sealing portion, a first connecting portion, an abutting portion, a second connecting portion and a second sealing portion, wherein the second sealing portion is connected to an upper end and / or a lower end of the abutting portion via the second connecting portion, the first sealing portion is connected to an upper end and / or a lower end of the abutting portion via the second connecting portion, or the first connecting portion is directly connected to the second connecting portion; the abutting portion is located between the first sealing portion and the second sealing portion, and the abutting portion can move or rotate relative to the first sealing portion and the second sealing portion under the action of an external force; so that When the abutting portion moves to the first position, a part of the abutting portion directly abuts or connects with the first sealing portion and the second sealing portion, and when the abutting portion moves to the second position, the abutting portion does not abut or connect with the first sealing portion or the second sealing portion; Or, when the abutting part rotates to the first position, the distance between the abutting part and the first sealing part and the second sealing part in abutment or connection position is the first distance, and when the abutting part rotates to the second position, the distance between the abutting part and the first sealing part and the second sealing part in abutment or connection position is the second distance, and the first distance is greater than the second distance.

[0007] Compared with the prior art, the automobile sunroof sealing ring and the use method thereof of the present application have the following beneficial effects: When the abutting portion is in the first position, the abutting portion abuts or connects with the first sealing portion and the second sealing portion to form a supporting effect on the first sealing portion and the second sealing portion, so that the sealing performance of the first sealing portion and the second sealing portion is better. When the abutting portion is in the second position, the abutting portion does not abut or connect with the first sealing portion or the second sealing portion, and cannot form a supporting effect on the first sealing portion and the second sealing portion, so that the elastic performance of the first sealing portion and the second sealing portion is better, which can reduce the force of opening the sunroof, reduce the resistance to opening, reduce wear and extend the service life. In addition, the car sunroof will not leak, so there is no need to design a water tank structure under the sunroof, making the structure simpler and not taking up more space, which can reduce the design cost of the sunroof as a whole.

[0008] In one embodiment, the first sealing portion is provided with a first sealing groove, so that a better fixed sealing connection can be formed.

[0009] In one possible implementation manner, the second sealing portion is provided with an arc-shaped sealing surface, which facilitates the relative movement of the contact surfaces and reduces movement resistance.

[0010] In one embodiment, the abutment portion includes a first rotating piece, a second rotating piece, a third rotating piece and a fourth rotating piece, and the first rotating piece, the second rotating piece, the third rotating piece and the fourth rotating piece are elastically connected or hinged end to end so that the cross section is rhombus-shaped, so that the first rotating piece and the fourth rotating piece rotate in the same direction, and the first rotating piece rotates in the opposite direction to the second rotating piece and the third rotating piece. In this way, one diagonal corner of the rhombus is close to the other diagonal corner and is far away from the other diagonal corner, and the distance of one diagonal corner can be adjusted to control the distance of the other diagonal corner, so that the size of the supporting force of the first sealing part and the second sealing part can be controlled, and the window can be opened conveniently under the premise of ensuring the sealing performance.

[0011] In one embodiment, the abutting portion includes an abutting section and a connecting section, and the width of the abutting section is greater than that of the connecting section, so that the abutting section can form a larger supporting force, and moving to the connecting section facilitates opening of the sunroof.

[0012] In one possible implementation manner, the abutting portion is in a shuttle-shaped structure, which has a relatively small resistance to movement and can form a certain elastic supporting force. In one embodiment, the abutting portion, the first connecting portion and the first sealing portion form a first sealed cavity, and the abutting portion, the second connecting portion and the second sealing portion form a second sealed cavity. Lubricant is provided in the first sealed cavity and the second sealed cavity. Such a design can reduce movement resistance.

[0013] According to the second aspect of the present application, a method for using a car sunroof sealing ring is provided. When the sunroof sealing ring is used, first confirm whether the abutting portion is in the second position. If it is not in the second position, move or rotate the abutting portion to the second position, then close the sunroof to the abutting position with the sealing ring, and finally move or rotate the abutting portion to the first position to ensure that the abutting portion abuts or connects with the first sealing portion and the second sealing portion. In this way, the resistance to closing the sunroof is small, and after closing, a tighter connection can be achieved by using the abutting portion to prevent water leakage in the car sunroof.

[0014] In one embodiment, when the sunroof is opened, the abutment portion is first moved or rotated from the first position to the second position, and then the sunroof is opened. In this way, the resistance is smaller when the sunroof is opened.

[0015] In one possible implementation manner, the abutting portion is provided with a driving structure to drive the abutting portion to move or rotate, so that the rotation or movement of the abutting portion can be conveniently controlled.

[0016] It should be understood that the content described in this section is not intended to identify the key or important features of the embodiments of the present application, nor is it intended to limit the scope of the present application. Other features of the present application will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0020] like Figure 1 As shown, a diagram of the installation and use state of a car sunroof sealing ring is shown, the sunroof frame 7 is located outside the car sunroof sealing ring, and the sunroof glass 6 is located inside the car sunroof sealing ring. In some embodiments, the car sunroof sealing ring can be fixed on the sunroof glass 6, and in some embodiments, the car sunroof glass 6 sealing ring can be fixed on the sunroof frame 7. Different installation methods can change the inner and outer structures of the car sunroof sealing ring. Up, down, left, right, front, and back are the directions in this use state.

[0021] Embodiment 1: like Figure 2 and Figure 3 As shown, a sealing ring for a car sunroof comprises 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, wherein the second sealing part 5 is connected to the upper end and the lower end of the abutting part 3 through the second connecting part 4, the first sealing part 1 is connected to the upper end and the lower end 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, and the abutting part 3 can move relative to the first sealing part 1 and the second sealing part 5 under the action of an external force; so that when the abutting part 3 moves to the first position, a part of the abutting part 3 directly abuts against the first sealing part 1 and the second sealing part 5, and the first sealing part 1 and the second sealing part 5 can be directly connected if the material with good elasticity is used, and when the abutting part 3 moves to the second position, the abutting part 3 does not abut 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 located on both sides of the abutting part 3, respectively.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the first sealing portion 1 is provided with a first sealing groove 11, and 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 arranged on the inner side of the sealing ring, the sunroof glass 6 can be installed in the first sealing groove 11, that is, the automobile sunroof sealing ring is fixed to the sunroof glass 6. When the first sealing groove 11 is arranged on the outer side of the sealing ring, the automobile sunroof sealing ring is installed on the sunroof frame 7.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the second sealing portion 5 is provided with an arc-shaped sealing surface 51. The arc-shaped sealing structure is convenient for relative movement with other structures and has a good sealing effect when in the center position. The sealing ring is usually made of elastic rubber material and has good elasticity, so the function of elastic deformation can be fully utilized to provide the sealing performance of the sealing ring. The second sealing portion 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.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the abutment portion 3 includes an abutment section 31 and a connecting section 30, and the width of the abutment section 31 is greater than the width of the connecting section 30. To facilitate the movement of the abutment portion 3, the abutment portion 3 is a shuttle-shaped structure, that is, the cross-section is close to a diamond shape, but the upper end can be designed to be shorter and wider, and the lower end can be designed to be narrower, so that the abutment section 31 and the connecting section 30 can be formed.

[0025] like Figure 3 and Figure 4 As shown, in one embodiment, the abutting portion 3, the first connecting portion 2, and the first sealing portion 1 form a first sealing cavity 10, and the abutting portion 3, the second connecting portion 4, and the second sealing portion 5 form a second sealing cavity 50, and the first sealing cavity 10 and the second sealing cavity 50 are provided with lubricant. The first connecting portion 2 includes a first upper connecting portion 21 and a first lower connecting portion 22, and 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, and the first upper connecting portion 21 and the first lower connecting portion 22 are made of elastic material so that the abutting portion 3 can 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, and 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, and the second upper connecting portion 23 and the second lower connecting portion 24 are made of elastic material so that the abutting portion 3 can move up and down without basically affecting the position of the second sealing portion 5. If the first connection part 2 and the second connection part 4 have high strength, only the first upper connection part 21 and the second upper connection part 23 or only the first lower connection part 22 and the second lower connection part 24 may be provided.

[0026] like Figure 3 and Figure 4 As shown, in one embodiment, the first sealing portion 1 is provided with a first protrusion 12, and the first protrusion 12 is provided with a first groove 13. When the abutting portion 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 portion 5. The first groove 13 has the function of limiting the position of the abutting portion 3. The first protrusion 12 or the abutting portion 3 is made of elastic material and can be deformed within a certain range.

[0027] like Figure 5 and Figure 6 As shown, in one embodiment, the abutting portion 3 is in the second position, the abutting portion 3 is separated from the first protrusion 12, and the supporting force of the abutting portion 3 on the first sealing portion 1 and the second sealing portion 5 is reduced, and the opening resistance of the sunroof is relatively small. In addition, to facilitate the movement of the abutting portion 3, the abutting portion 3 is provided with a moving rod 94, and the driving component drives the moving rod 94 to move to realize the movement control of the abutting portion 3.

[0028] Embodiment 2: like Figure 7As 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, wherein the second sealing part 5 is connected to the upper end and the lower end of the abutting part 3 through the second connecting part 4, the first sealing part 1 is connected to the upper end and the lower end 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, and the abutting part 3 can rotate relative to the first sealing part 1 and the second sealing part 5 under the action of an external force; so that when the abutting part 3 rotates to the first position, the spacing between the abutting or connecting position of the abutting part 3 and the first sealing part 1 and the second sealing part 5 is a first spacing, and when the abutting part 3 rotates to the second position, the spacing between the abutting or connecting position of the abutting part 3 and the first sealing part 1 and the second sealing part 5 is a second spacing, and the first spacing is greater than the second spacing. The abutting portion 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 have a certain rigidity and are elastically connected or hinged end to end so that the cross-section is diamond-shaped, so that the first rotating piece 32 and the fourth rotating piece 35 have the same rotation direction, and the first rotating piece 32 and the second rotating piece 33 and the third rotating piece 34 rotate in opposite directions. The length of the first rotating piece 32 is greater than that of the third rotating piece 34, and the length of the second rotating piece 33 is greater than that of the fourth rotating piece 35. In this way, the second sealing portion 5 receives a greater support force corresponding to a greater displacement of the abutting portion 3.

[0029] The material of the abutment part 3 is different from that of the connection part. The first connection part 2 and the second connection part 4 are both made of elastic rubber, while the abutment part 3 is made of a material with stronger rigidity. The third rotating piece 34 and the fourth rotating piece 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 piece 34 and the fourth rotating piece 35.

[0030] like Figure 8 and Fig. 9 As shown, an upper baffle 8 is provided at the upper end of the abutting portion 3, and the upper end of the upper baffle 8 is designed to be an arc surface to reduce wind resistance. A lower baffle 9 is provided at the lower end of the abutting portion 3, and the lower baffle 9 is designed to be a plane structure. The lateral width of the abutting portion 3 can be controlled by adjusting the spacing between the upper baffle 8 and the lower baffle 9, that is, when the spacing between the upper baffle 8 and the lower baffle 9 is reduced, the upper ends of the first rotating piece 32 and the third rotating piece 34 move downward and the lower ends move to both sides when they are rotated, and similarly, the lower ends of the second rotating piece 33 and the fourth rotating piece 35 move upward and the upper ends move to both sides, so that a stronger supporting effect can be formed on the first sealing portion 1 and the second sealing portion 5 to ensure the sealing performance; when the spacing between the upper baffle 8 and the lower baffle 9 is increased, the first rotating piece 32, the second rotating piece 33, the third rotating piece 34 and the fourth rotating piece 35 rotate in opposite directions to reduce the supporting force, thereby facilitating the opening of the sunroof.

[0031] like Figure 8 and Fig. 9As shown, the upper baffle 8 is provided with a screw 90, and a limiting wheel 91 is provided under the lower baffle 9. The limiting wheel 91 is provided with a threaded hole that matches the screw 90. The spacing between the upper baffle 8 and the lower baffle 9 can be controlled by rotating the limiting wheel 91. The limiting wheel 91 is provided with an input part 92 and an output part 93. Since the upper baffle 8 is relatively long, it is necessary to set a plurality of limiting wheels 91 to simultaneously control the spacing between the upper baffle 8 and the lower baffle 9. It is costly to set a plurality of driving structures, so adjacent limiting wheels 91 are linked, 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 realize transmission, such as through belt transmission, that is, two limiting wheels 91 are connected by a belt. In addition, the limiting wheel 91 can also be designed as a structure that is driven by different transmission methods such as sprockets, gears and winches, which can reduce the number of driving structures and reduce the driving cost.

[0032] Embodiment 3: like Fig.10 As shown, the first rotating piece 32 is provided with a first supporting piece 36, the second rotating piece 33 is provided with a second supporting piece 37, the third rotating piece 34 is provided with a third supporting piece 38, and the fourth rotating piece 35 is provided with a fourth supporting piece 39. The first rotating piece 32, the second rotating piece 33, the third rotating piece 34 and the fourth rotating piece 35 are manufactured by a rubber encapsulation process, that is, the first supporting piece 36, the second supporting piece 37, the third supporting piece 38 and the fourth supporting piece 39 are first manufactured, and then the first supporting piece 36, the second supporting piece 37, the third supporting piece 38 and the fourth supporting piece 39 are coated with rubber material on the outside or on one side. The first supporting piece 36, the second supporting piece 37, the third supporting piece 38 and the fourth supporting piece 39 need to be made of a material with good rigidity and certain toughness, such as PE, PC, PVC, etc. The abutting part 3 can be processed and manufactured separately and then placed inside the sealing ring, or it can be integrally formed with the sealing ring. The integral molding process is more complicated, but the production efficiency is higher. Since the sealing ring is relatively wide, it can be formed into a ring structure by heat fusion after segmented manufacturing, and the curved part can be manufactured separately.

[0033] Embodiment 4: like Fig.11As shown, in one embodiment, the automobile sunroof sealing ring is made of transparent silicone rubber material, a fourth cavity 40 is provided between the second lower connecting part 24 and the fourth rotating piece 35, a granular hydrogel 41 is placed in the fourth cavity 40, a water-conducting rubber strip 43 is provided on the side of the second lower connecting part 24, and the water-conducting rubber strip 43 is provided with a water-conducting hole to communicate with the fourth cavity 40, so that when the second sealing part 5 leaks locally, the water can be guided to the fourth cavity 40 through the water-conducting rubber strip 43, and the hydrogel 41 can swell after encountering water, so that the sealing performance of the second sealing part 5 is better. In order to ensure that the water absorption can be evenly diffused, a water-absorbing fiber material 42 is mixed between the granular hydrogel 41, and the use of plant fiber materials such as cotton has a shorter service life. The fourth cavity 40 is provided with an opening to replace the hydrogel 41 from the opening. The four corners of the automobile sunroof are usually prone to water leakage. The four corners can also be manufactured separately to form four independent fourth cavities 40, and then the hydrogel 41 is placed in the fourth cavity 40. The four corners and four edges are thermally welded to form the automobile sunroof sealing ring.

[0034] Embodiment 5: like Fig.12 As 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, the abutting part 3 can be inserted into the area between the first connecting part 2 and the second connecting part 4 after manufacturing, the length of the first rotating piece 32 is greater than the length of the third rotating piece 34, 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 relying on the control of the screw rod 90 and the limiting wheel 91, and the first rotating piece 32 and the second rotating piece 33 are elastically connected and can be reset by elastic force.

[0035] Embodiment 6: like Fig.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 upper ends of the third rotating piece 34 are elastically connected or hinged so 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 rotated by the control of the screw rod 90 and the limiting wheel 91. When the upper ends of the first rotating piece 32 and the third rotating piece 34 move downward, the left and right ends of the first rotating piece 32 and the third rotating piece 34 move outward to provide greater supporting force. Fig.14 As shown, after the screw rod 90 moves downward, the distance between the first sealing portion 1 and the second sealing portion 5 increases, and the supporting force of the abutting portion 3 also increases.

[0036] Embodiment 7: like Figure 1-10As shown, a method for using a car sunroof sealing ring is used. When the car sunroof sealing ring in the above embodiment is used, first confirm whether the abutting portion 3 is in the second position. If it is not in the second position, move or rotate the abutting portion 3 to the second position, then close the sunroof to the abutting position with the sealing ring, and finally move or rotate the abutting portion 3 to the first position to ensure that the abutting portion 3 abuts or connects with the first sealing portion 1 and the second sealing portion 5. When the abutting portion 3 moves, the supporting force on the first sealing portion 1 and the second sealing portion 5 can be changed, so that the sealing performance can be improved or the opening resistance of the sunroof can be reduced.

[0037] In one embodiment, when the sunroof is opened, the contact portion 3 is first moved or rotated from the first position to the second position, and then the sunroof is opened.

[0038] In one embodiment, the abutting portion 3 is provided with a driving structure to drive the abutting portion 3 to move or rotate. The driving structure can be a linear motion driving structure or a rotation driving structure. Some embodiments require linear movement, and some embodiments require rotation.
