Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a zero-step differential door glass sealing strip, a zero-step differential door, and a vehicle. Background Technology

[0002] Zero-step door refers to a design that achieves a seamless connection between the door glass and the exterior body panel. By eliminating the visible step difference of traditional doors, the side of the entire vehicle presents a mirror-like smooth effect.

[0003] Specifically, the zero-step differential door uses sliders attached to both sides of the glass, allowing the glass to slide and rise along grooves within the sealing strip. The precise fit between the sliders and the sealing strip ensures that the glass remains flush with the B-pillar and C-pillar trim panels during movement, achieving a stepless visual effect.

[0004] Because the zero-step differential door glass sealing strip needs to provide a limiting function for the glass, its structure is more complex and its cost is higher. Furthermore, compared to traditional doors with stepped differentials, the assembly of the door glass in a zero-step differential door is more difficult and takes longer, affecting the entire door assembly process and resulting in wasted time. Utility Model Content

[0005] In view of this, the present invention provides a zero-step differential door glass sealing strip, a zero-step differential door, and a vehicle, to solve the problems of complex structure and high cost of the zero-step differential door glass sealing strip.

[0006] The zero-step differential door glass sealing strip provided by this utility model includes: an upper sealing strip and a lower sealing strip. The upper sealing strip is used to connect with the upper section guide rail of the side window glass, and the lower sealing strip is used to connect with the lower section guide rail of the side window glass. The upper sealing strip has a lip-shaped sealing structure for mating with the side window glass, and the lower sealing strip has a bubble-shaped sealing structure.

[0007] In this invention, the lower sealing strip uses a bubble-shaped sealing structure instead of the lip-shaped sealing structure of the upper sealing strip. The cross-sectional area of ​​the bubble-shaped sealing structure is smaller than that of the lip-shaped sealing structure, thus reducing the amount of material used while ensuring sealing performance. Furthermore, the bubble-shaped sealing structure is simpler, requiring no complex shape design, and its manufacturing process is also relatively simple. Combined with material savings, these two factors effectively reduce the overall cost.

[0008] Optionally, the bubble-like sealing structure has a semi-circular outer surface. The semi-circular outer surface can better conform to the glass slider on the side window glass, thereby improving the sealing effect.

[0009] Optionally, the semi-circular outer surface has a nap or a smoothing material. The nap increases the contact area with the side window glass, ensuring the stability and reliability of the seal. The smoothing material reduces the friction between the sealing strip and the glass slider, allowing the sealing strip to slide better on the glass slider.

[0010] Optionally, the lip-shaped sealing structure includes a plurality of spaced-apart rubber strips, each strip having a nap or a smoothing material. The nap increases the contact area with the side window glass, ensuring the stability and reliability of the seal. The smoothing material reduces the friction between the sealing strip and the glass slider, allowing the sealing strip to slide more smoothly on the glass slider.

[0011] Optionally, the upper sealing strip has a first groove for connecting to the window frame. The first groove provides precise positioning between the upper sealing strip and the window frame, strengthens the connection between the upper sealing strip and the window frame, and improves the structural stability of the entire door glass sealing system.

[0012] Optionally, the upper sealing strip has a second slot for connecting to the vehicle door. The second slot provides precise positioning between the upper sealing strip and the vehicle door, strengthens the connection between the upper sealing strip and the vehicle door, and improves the structural stability of the entire door glass sealing system.

[0013] Optionally, the upper sealing strip and the lower sealing strip each have a groove for embedding in the guide rail, one side of the groove has an extension extending toward the side window glass, the end of the extension is bent outward, and the upper sealing strip has an arc-shaped soft rubber extending from the bent extension toward the side window glass.

[0014] In the above design, the fit between the groove and the guide rail allows the sealing strip to be securely fixed to the guide rail. The outward bending design at the end of the extension section makes the groove's containment of the guide rail more flexible. The curved soft rubber extending from the bent extension section towards the side window glass on the upper sealing strip creates an additional sealing barrier. When the side window glass is closed, the curved soft rubber can fit tightly against the glass surface, working together with the existing sealing structure to further improve the sealing effect.

[0015] Optionally, the curved soft rubber has a sliding material. The sliding material can reduce the friction between the sealing strip and the glass slider, allowing the sealing strip to slide better on the glass slider.

[0016] This utility model also provides a zero-step differential door, comprising: a zero-step differential door glass sealing strip as described in any of the above embodiments, wherein the upper sealing strip and the lower sealing strip have a spacing of 5-30mm.

[0017] This utility model also provides a vehicle, including: an A-pillar strip, a B-pillar strip, and a C-pillar strip, wherein the B-pillar strip is provided with a zero-step differential door glass sealing strip as described in any of the above-described schemes; or, the A-pillar strip and the C-pillar strip are also provided with a zero-step differential door glass sealing strip as described in any of the above-described schemes.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not 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 of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1-5As shown, this is a specific implementation of the zero-step differential door glass sealing strip provided in this embodiment, including: an upper sealing strip 1 and a lower sealing strip 2. The upper sealing strip 1 is used to connect with the upper section guide rail 5 of the side window glass, and the lower sealing strip 2 is used to connect with the lower section guide rail 6 of the side window glass.

[0026] like Figure 2 , Figure 3 As shown, the upper sealing strip 1 has a lip-shaped sealing structure 101 for cooperating with the side window glass 3, and the lower sealing strip 2 has a bubble-shaped sealing structure 201. The cross-sectional area of ​​the bubble-shaped sealing structure 201 is smaller than the cross-sectional area of ​​the lip-shaped sealing structure 101.

[0027] In this invention, the lower sealing strip 2 uses a bubble-shaped sealing structure 201. The cross-sectional area of ​​the bubble-shaped sealing structure 201 is smaller than that of the lip-shaped sealing structure 101, thus reducing material usage while ensuring sealing performance. Furthermore, the bubble-shaped sealing structure 201 is relatively simple, requiring no complex shape design, and its manufacturing process is also relatively straightforward. This structural simplification improves production efficiency, and combined with material savings, effectively reduces the overall cost.

[0028] like Figure 3 , Figure 5 As shown, the bubble-shaped sealing structure 201 has a semi-circular outer surface. The semi-circular outer surface can better fit the glass slider 4 on the side window glass 3, thereby improving the sealing effect.

[0029] like Figure 3 , Figure 5 As shown, the semi-circular outer surface has a nap or smooth material.

[0030] like Figure 2 , Figure 4 As shown, the lip-shaped sealing structure 101 includes two spaced-apart rubber strips, each with a nap or a slip material. The two rubber strips can engage with the side window glass 3 from multiple positions, forming multiple lines of defense for sealing. Specifically, the napped rubber strip is used for sliding engagement with the side window glass 3, thereby forming multiple lines of defense for sealing. The nap increases the contact area with the side window glass, ensuring the stability and reliability of the seal. When a slip material is used, it reduces the friction between the sealing strip and the glass slider, allowing the sealing strip to slide better on the glass slider. Specifically, the slip material can be a coating with low sliding friction, such as a plastic particle coating.

[0031] like Figure 2As shown, the upper sealing strip 1 has a first slot 102 for connecting the window frame 901. The first slot 102 provides precise positioning for the upper sealing strip 1 and the window frame 901, strengthens the connection between the upper sealing strip 1 and the window frame 901, and improves the structural stability of the entire door 902 glass sealing system.

[0032] like Figure 2 As shown, the upper sealing strip 1 has a second slot 103 for connecting to the door 902. The second slot 103 provides precise positioning between the upper sealing strip 1 and the door 902, strengthens the connection between the upper sealing strip 1 and the door 902, and improves the structural stability of the entire door 902 glass sealing system. Of course, the above description is not limiting; in some alternative embodiments, the second slot 103 may be omitted.

[0033] like Figures 2-5 As shown, the upper sealing strip 1 and the lower sealing strip 2 each have a groove 7 for embedding in the guide rail. One side of the groove 7 has an extension 701 extending toward the side window glass 3. The end of the extension 701 is bent outward 702. The upper sealing strip 1 has an arc-shaped soft rubber 703 extending from the extension 701 of the bent 702 toward the side window glass 3.

[0034] In the above design, the cooperation between the groove 7 and the guide rail allows the sealing strip to be firmly fixed to the guide rail. The design of the outward bending 702 at the end of the extension 701 makes the enclosure of the groove 7 on the guide rail more flexible. The arc-shaped soft rubber 703 extending from the extension 701 of the bend 702 towards the side window glass 3 on the upper sealing strip 1 creates an additional sealing barrier. When the side window glass 3 is closed, the arc-shaped soft rubber 703 can fit tightly against the glass surface, working together with the existing sealing structure to further improve the sealing effect.

[0035] like Figure 2 , Figure 4 As shown, the arc-shaped soft rubber 703 has a sliding material. This sliding material reduces the friction between the sealing strip and the glass slider, allowing the sealing strip to slide more smoothly on the glass slider. Specifically, the sliding material can be a coating with low sliding friction, such as a plastic particle coating.

[0036] On the other hand, an embodiment of this utility model also provides a zero-step differential door 902, including: the zero-step differential door glass sealing strip described in the above solution, wherein the upper sealing strip 1 and the lower sealing strip 2 have a spacing of 5-30mm.

[0037] like Figure 6As shown, an embodiment of this utility model also provides a vehicle, including: an A-pillar strip 8, a B-pillar strip 9, and a C-pillar strip 10. The B-pillar strip 9 is provided with the zero-step differential door glass sealing strip described in the above-mentioned solution. By using the zero-step differential door glass sealing strip provided in this embodiment, the lower sealing strip 2 on the B-pillar strip 9 is replaced with a bubble-shaped sealing structure 201 instead of a lip-shaped sealing structure 101, which can save 40% of the sealing strip material.

[0038] like Figure 7 As shown, in some embodiments, the end of the lower section guide rail 6 of the side window glass has a hook-shaped structure 903. After the hook-shaped structure 903 is bent 702, it is inserted into the bubble-shaped sealing structure 201 of the lower sealing strip 2, thereby pressing down the end section of the bubble-shaped sealing structure 201 to prevent the glass from getting stuck when it descends.

[0039] In addition, in some embodiments, the A-pillar strip 8 and C-pillar strip 10 are also provided with the zero-step differential door glass sealing strip described in the above scheme. By using the zero-step differential door glass sealing strip provided in this embodiment, the lower sealing strip 2 on the A-pillar strip 8 or C-pillar strip 10 is replaced with a bubble sealing structure 201 instead of a lip sealing structure 101, which can save 30% of the sealing strip material.

[0040] like Figure 8 , Figure 9 As shown, in some embodiments, the zero-step door glass sealing strip for the A-pillar strip 8 and the C-pillar strip 10 includes: an upper sealing strip 1 and a lower sealing strip 2, wherein the upper sealing strip 1 is used to connect with the upper section guide rail 5 of the side window glass, and the lower sealing strip 2 is used to connect with the lower section guide rail 6 of the side window glass.

[0041] like Figure 8 , Figure 9 As shown, the upper sealing strip 1 has a lip-shaped sealing structure 101 for cooperating with the side window glass 3, and the lower sealing strip 2 has a bubble-shaped sealing structure 201. The cross-sectional area of ​​the bubble-shaped sealing structure 201 is smaller than the cross-sectional area of ​​the lip-shaped sealing structure 101.

[0042] like Figure 8 , Figure 10 As shown, the lip-shaped sealing structure 101 includes two spaced-apart rubber strips, each strip having a nap or slip material. The two rubber strips can engage with the side window glass 3 from multiple positions, forming multiple lines of sealing. Specifically, the napped rubber strip is used for sliding engagement with the side window glass 3, thereby forming multiple lines of sealing.

[0043] like Figure 9 , Figure 11 As shown, the semi-circular outer surface has a nap or smooth material.

[0044] In summary, the technical solution of this embodiment has the following characteristics: 1. In the technical solution of this embodiment, the lip-shaped sealing structure 101 of the upper sealing strip 1 is composed of two spaced rubber strips, forming multiple sealing defenses, which can work together with the side window glass 3 from multiple positions, thereby enhancing the sealing effect.

[0045] 2. In this embodiment, after the end of the extension section 701 of the groove 7 of the upper sealing strip 1 is bent 702, the extended arc-shaped soft rubber 703 will tightly adhere to the glass surface when the side window glass 3 is closed. It works in conjunction with the lip-shaped sealing structure 101 to further improve the sealing effect.

[0046] 3. In the technical solution of this embodiment, the bubble-shaped sealing structure 201 of the lower sealing strip 2 has a semi-arc outer surface. This shape can better fit the glass slider 4 on the side window glass 3, thereby improving the sealing effect.

[0047] 4. In the technical solution of this embodiment, the first groove 102 and the second groove 103 of the upper sealing strip 1 provide precise positioning for the upper sealing strip 1 and the window frame 901 and the door 902, respectively, which strengthens the connection strength and improves the structural stability of the entire door 902 glass sealing system.

[0048] 5. In this embodiment, the lower sealing strip 2 adopts a bubble-shaped sealing structure 201, whose cross-sectional area is smaller than that of the lip-shaped sealing structure 101. This reduces material usage while ensuring sealing performance. Specifically, using this sealing strip on the B-pillar strip 9 can save 40% of material, and using it on the A-pillar strip 8 or C-pillar strip 10 can save 30% of material.

[0049] 6. In this embodiment, the bubble-shaped sealing structure 201 has a relatively simple shape, requiring no complex design and simplifying the manufacturing process. This not only improves production efficiency but also reduces overall costs.

[0050] 7. In this embodiment, the hook-shaped structure 903 at the end of the lower guide rail 6 of the side window glass is bent 702 and then inserted into the bubble-shaped sealing structure 201 of the lower sealing strip 2, pressing down the end section of the bubble-shaped sealing structure 201. This changes the stress state of the sealing strip when the glass descends, effectively preventing jamming during the glass descent and ensuring smooth glass lifting and lowering.

[0051] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
