Description
A window sealing strip and vehicle Technical Field
[0001] This utility model relates to the field of vehicle parts technology, specifically to a window sealing strip and a vehicle. Background Technology
[0002] Currently, an increasing number of car models are adopting frameless doors. To prevent water leakage at the windows, window seals are typically installed on the side panels of the vehicle to seal the gap between the decorative trim and the window glass. When the door is closed, the window glass presses against the window seal along the Y-axis (i.e., the left-right direction of the vehicle body), causing the seal to cover the upper part of the window glass, thus achieving a seal. When the door is closed and the window is raised to close it, the upper part of the window glass presses upward against the window seal, again covering the upper part of the window glass, thus achieving a seal. However, in related technologies, the interference between the deformed window seal and the window glass is relatively small, resulting in a poor sealing effect. Summary of the Invention
[0003] The problem this invention addresses is: how to improve the sealing effect between the car window glass and the window sealing strip.
[0004] To solve the above problems, this utility model provides a window sealing strip and a vehicle.
[0005] In a first aspect, this utility model provides a window sealing strip for being disposed above the window glass and between the decorative bright strip and the window glass. The window sealing strip has a groove and a cavity extending along its length. The cross-section of the cavity is a closed ring structure. The groove is disposed on the outer surface of the window sealing strip. The window sealing strip is used to abut against the upper surface of the window glass at the groove and to abut against the decorative bright strip.
[0006] Optionally, the window sealing strip includes a first sealing portion and a second sealing portion extending along its length, the first sealing portion and the second sealing portion forming the cavity; the first sealing portion includes a first sealing section, a thinning section, an abutting section and a second sealing section, the first sealing section, the thinning section, the abutting section, the second sealing section and the second sealing portion are connected end to end in sequence to form the cavity, the groove is provided on the outer surface of the abutting section, the first sealing section and the second sealing section are respectively used to abut and seal with the decorative bright strip, and the material thickness of the thinning section is less than the material thickness of the first sealing section, the abutting section and the second sealing section.
[0007] Optionally, when the window glass is inserted into the groove, the thinned section is located on the side of the window glass facing outwards.
[0008] Optionally, when the window glass is inserted into the groove, the farthest edge point of the first sealing part in the vertical direction of the vehicle body is located on the side of the window glass facing outwards, wherein the farthest edge point of the first sealing part in the vertical direction is the part of the first sealing part that is farthest from the center point of the cavity in the vertical direction when the first sealing part is in its natural state.
[0009] Optionally, in the vertical direction, the distance between the center point of the thinned section and the farthest edge point of the first sealing part is h, and the distance between the farthest edge point of the first sealing part and the outer bright strip part of the decorative bright strip is H, and the ratio of h to H is between 0.3 and 0.35.
[0010] And / or, in a direction perpendicular to the window glass, the distance between the center point of the thinned section and the outer bright strip portion of the decorative bright strip is a, the distance between the outer surface of the window glass and the outer bright strip portion of the decorative bright strip is b, and the ratio of a to b is between 0.3 and 0.35.
[0011] The outer bright strip portion of the decorative bright strip is the part of the decorative bright strip located on the side of the vehicle window glass facing outwards.
[0012] Optionally, the abutting section has a first protrusion extending along the length of the window sealing strip on one side of the cavity. When the window glass is inserted into the groove, the first protrusion is located on the side of the window glass facing outward and is used to abut against the first sealing section. The squeezing force between the first protrusion and the first sealing section has a component force in the direction perpendicular to the window glass.
[0013] Optionally, the first sealing section has a plurality of second protrusions extending along the length of the window sealing strip on one side of the cavity, and at least one of the plurality of second protrusions is used to abut against the first protrusion when the window glass is inserted into the groove.
[0014] Optionally, the height of the second protrusion is less than the height of the first protrusion.
[0015] Optionally, the second sealing section is provided with a first sealing protrusion extending along the length direction of the window sealing strip on the side outside the cavity. The first sealing protrusion is used to be located below the inner bright strip portion of the decorative bright strip and to abut against and seal with the inner bright strip portion.
[0016] And / or, the second sealing part is provided with a second sealing protrusion extending along the length direction of the window sealing strip on the side outside the cavity, and the second sealing protrusion is used to be inserted into the sealing slot on the outer bright strip part of the decorative bright strip;
[0017] The outer bright strip portion of the decorative bright strip is the part of the decorative bright strip located on the side of the vehicle window glass facing outwards, and the inner bright strip portion of the decorative bright strip is the part of the decorative bright strip located on the side of the vehicle window glass facing inwards.
[0018] Secondly, this utility model provides a vehicle including the window sealing strip described above.
[0019] The beneficial effects of this utility model's window sealing strip are: by setting a cavity with a closed-loop cross-section, deformation space is provided for the window sealing strip; simultaneously, by setting a groove on the outer surface of the window sealing strip, and positioning the groove corresponding to the window glass, when the window glass is inserted into the groove and presses against the window sealing strip along, for example, the Z-axis direction (i.e., the vertical direction of the vehicle body), or when the window sealing strip is pressed against the groove along, for example, the Y-axis direction (i.e., the horizontal direction of the vehicle body), the groove design prevents significant deformation of the part of the window sealing strip that abuts against the window glass along the Z-axis direction, while also allowing for greater deformation of the window glass. The area of coverage is large, and because the deformation of the window seal strip along the Z-axis is small, it avoids the small amount of contact between the window seal strip and the side of the window glass caused by the large deformation of the groove walls along the Z-axis. This ensures that there is a sufficiently large amount of interference between the window glass and the window seal strip, improving the sealing effect. Moreover, when the window glass is inserted into the groove, the two groove sidewalls along the Y-axis approach each other and adhere tightly to the surface of the window glass, thereby increasing the contact area between the window seal strip and the window glass. This ensures that the window seal strip can completely cover the upper part of the window glass, further improving the sealing effect. Attached Figure Description

[0030] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".
[0031] In related technologies, an increasing number of car models are adopting frameless doors. To prevent water leakage at the windows, sealing strips are typically installed on the side panels of the vehicle body to seal the assembly gap between the decorative trim and the window glass. When the door is closed, the window glass presses against the sealing strip along the Y-axis (left-right direction of the vehicle body), causing the sealing strip to cover the upper part of the window glass, thus achieving a seal. When the door is closed and the window glass rises to close it, the upper part of the window glass presses upward against the sealing strip, causing it to cover the upper part of the window glass, thus achieving a seal. However, commercially available window sealing strips, after being deformed by compression, exhibit significant deformation in the Z-axis direction (vertical direction of the vehicle body). This results in a smaller interference between the sealing strip and the window glass (i.e., the distance between the lowest point of the sealing strip and the upper surface of the window glass), leading to a poor sealing effect.
[0032] In view of the problems existing in the above-mentioned related technologies, this utility model provides a window sealing strip and a vehicle.
[0033] It should be noted that the window sealing strip 100 of this utility model can be applied to both framed and frameless vehicle models. Specifically, when applied to a framed vehicle model, the window sealing strip 100 is mounted on the door window frame; when applied to a frameless vehicle model, it is mounted on the A, B, and C pillars of the vehicle's side panel. For ease of description, the following explanation will use a frameless vehicle model as an example.
[0034] It should also be noted that the window sealing strip 100 of this utility model can be applied to both vehicles with triangular windows and vehicles without triangular windows. When the window sealing strip 100 is applied to a vehicle with a triangular window, the window glass 600 includes a front window glass 610, a rear window glass 620, and a corner window glass 630. Correspondingly, the window sealing strip 100 includes a front window sealing strip for pressing and sealing with the front window glass 610, a rear window sealing strip for pressing and sealing with the rear window glass 620, and a corner window sealing strip for pressing and sealing with the corner window glass 630. Moreover, for frameless doors, the front window sealing strip, the rear window sealing strip, and the corner window sealing strip constitute a single window sealing strip. For doors with window frames, the front window sealing strip and the rear window sealing strip are two independent sealing strip structures. The corner window sealing strip can be an independent sealing strip structure or it can form a single sealing strip with the window sealing strip of the corresponding door. For example, the front corner window sealing strip is integrally formed with the front window sealing strip, and the rear corner window sealing strip is integrally formed with the rear window sealing strip.
[0035] Referring to Figures 1 to 4, the present invention provides a window sealing strip 100, which is used to be disposed above the window glass 600 and between the decorative bright strip 500 and the window glass 600. The window sealing strip 100 is provided with a groove 15 and a cavity 3 extending along its length direction. The cross-section of the cavity 3 is a closed ring structure. The groove 15 is disposed on the outer surface of the window sealing strip 100. The window sealing strip 100 is used to abut against the upper end face of the window glass 600 at the groove 15 and to abut against the decorative bright strip 500.
[0036] It should be noted that a sealing strip structure can be installed around the entire edge of the window glass 600 for sealing. The sealing strip located at the upper edge of the window glass 600 can be called the upper window sealing strip, the sealing strip located at the lower edge of the window glass 600 can be called the lower window sealing strip, and the sealing strip located at the front edge / or rear edge of the window glass 600 can be called the side window sealing strip. In this embodiment, the window sealing strip 100 usually refers to the upper window sealing strip.
[0037] Specifically, the window sealing strip 100 is a long strip-shaped sealing strip structure that extends along the upper edge of the window glass 600. The window sealing strip 100 has a cavity 3 and a groove 15 extending along its length direction. The cavity 3 penetrates the end faces of both ends of the window sealing strip 100 along its length direction, and the cross-section of the cavity 3 is a closed ring structure. The part of the window sealing strip 100 that abuts against the window glass 600 is recessed into the cavity 3 along the Z-axis direction in Figure 2 to form a groove 15, and the groove wall of the groove 15 abuts against the upper end face of the window glass 600. For frameless models, the window sealing strip 100 is installed on the side panel of the vehicle body. When the doors are closed, when the window glass 600, for example, the front window glass 610 / rear window glass 620, rises to close the window, the upper end of the front window glass 610 / rear window glass 620 moves upward along the vertical direction of the vehicle body (i.e., the Z-axis direction in Figure 4, referred to as the vertical direction) to insert into the groove 15 and compress the window sealing strip 100, so that the window sealing strip 100 covers the... The upper end of the window glass 600 forms a seal. When the car door is closed, the window glass 600 presses against the window sealing strip 100 along the left-right direction of the car body (i.e., the Y-axis direction in Figure 4, referred to as the left-right direction). When the window sealing strip 100 deforms due to the compression, it slides into the groove 15 of the window sealing strip 100, so that the upper end of the window glass 600 is inserted into the groove 15. At the same time, the window sealing strip 100 covers the upper end of the window glass 600 to form a seal. Furthermore, the inner surface of the groove 15 can be arc-shaped, which on the one hand facilitates the upper end of the window glass 600 to slide into the groove 15, and on the other hand allows the groove 15 and the arc-shaped upper surface of the window glass 600 to have a larger contact area, thereby further ensuring the sealing effect.
[0038] In this embodiment, the window sealing strip 100 can be provided with a cavity 3 having a closed-loop cross-section to provide deformation space. Simultaneously, by providing a groove 15 on the outer surface of the window sealing strip 100, and positioning the groove 15 corresponding to the window glass 600, when the window glass 600 is inserted into the groove 15 along, for example, the Z-axis direction (i.e., the vertical direction of the vehicle body) and presses against the window sealing strip 100, or when the window sealing strip 100 is pressed along, for example, the Y-axis direction (i.e., the horizontal direction of the vehicle body) and inserted into the groove 15, the groove 15 prevents significant deformation of the portion of the window sealing strip 100 that contacts the window glass 600 along the Z-axis direction. This also allows for a larger area of contact between the window sealing strip 100 and the window glass 600. The window sealing strip 100 has a small deformation along the Z-axis, which avoids the small amount of contact between the window sealing strip 100 and the window glass 600 caused by the large deformation of the two side walls of the groove 15 along the Z-axis. This ensures that there is a sufficiently large amount of interference between the window glass 600 and the window sealing strip 100, improving the sealing effect. Moreover, when the window glass 600 is inserted into the groove 15, the two side walls of the groove 15 along the Y-axis approach each other and adhere tightly to the surface of the window glass 600, thereby increasing the contact area between the window sealing strip 100 and the window glass 600. This ensures that the window sealing strip 100 can completely cover the upper end of the window glass 600, further improving the sealing effect.
[0039] Optionally, as shown in Figures 2 and 3, the window sealing strip 100 includes a first sealing portion 1 and a second sealing portion 2 extending along its length, forming a cavity 3. The first sealing portion 1 includes a first sealing section 11, a thinning section 12, an abutting section 13, and a second sealing section 14. The first sealing section 11, the thinning section 12, the abutting section 13, the second sealing section 14, and the second sealing portion 2 are connected end to end in sequence to form the cavity 3. A groove 15 is provided on the outer surface of the abutting section 13. The first sealing section 11 and the second sealing section 14 are respectively used to abut and seal with the decorative bright strip 500, and the material thickness of the thinning section 12 is less than the material thickness of the first sealing section 11, the abutting section 13, and the second sealing section 14.
[0040] In this optional embodiment, the window sealing strip 100 includes a first sealing portion 1 and a second sealing portion 2 distributed along the vertical direction of the vehicle body. The lower first sealing portion 1 is used for compression sealing with the window glass 600 and for abutting sealing with the decorative bright strip 500. The upper second sealing portion 2 is also used for abutting sealing with the decorative bright strip 500. The first sealing portion 1 and the second sealing portion 2 can be an integral structure. Moreover, both the first sealing portion 1 and the second sealing portion 2 are elongated structures and together form a cavity 3. The portion of the first sealing portion 1 that abuts against the window glass 600 is recessed into the cavity 3 along the Z-axis direction in Figure 2 to form a groove 15, and the groove 15 extends from one end of the first sealing portion 1 along its length direction to the other end. The first sealing part 1 is mainly composed of four parts, namely the first sealing section 11, the thinning section 12, the abutting section 13 and the second sealing section 14. The first sealing section 11 and the second sealing section 14 are used to form two opposite side walls of the cavity 3, the thinning section 12 and the abutting section 13 are used to form the bottom wall of the cavity 3, and the outer surface of the abutting section 13 forms a groove 15 structure. In this way, by using the first sealing section 11 and the second sealing section 14 to abut and seal with the decorative bright strip 500, the seal between the first sealing part 1 and the decorative bright strip 500 can be achieved. At the same time, by setting a thinning section 12 between the first sealing section 11 and the abutting section 13, and setting the material thickness of the thinning section 12 to be less than the material thickness of the first sealing section 11, the abutting section 13 and the second sealing section 14, the thinning section 12 is the part with the smallest material thickness on the first sealing part 1. In this way, when the window glass 600 presses the first sealing part 1 along the Z-axis direction, the first sealing part 1 is easy to bend and deform at the thinning section 12, thereby preventing the abutting section 13 from undergoing a large amount of deformation in the Z-axis direction, so as to increase the amount of interference between the window glass 600 and the window sealing strip 100 and improve the sealing effect.
[0041] Optionally, as shown in Figure 5, when the window glass 600 is inserted into the groove 15, the thinning section 12 is located on the side of the window glass 600 facing outwards. This increases the amount of contact between the groove wall of the groove 15 near the outer surface of the window glass 600 and the outer surface of the window glass 600, thereby ensuring a sufficiently large amount of interference between the outer surface of the window glass 600 and the window sealing strip 100, and improving the sealing effect.
[0042] Optionally, as shown in Figure 5, when the window glass 600 is inserted into the groove 15, the farthest edge point of the first sealing part 1 in the vertical direction of the vehicle body is located on the side of the window glass 600 facing outwards. The farthest edge point of the first sealing part 1 in the vertical direction is the part of the first sealing part 1 that is farthest from the center point of the cavity 3 in the vertical direction when the first sealing part 1 is in its natural state.
[0043] In this optional embodiment, as shown in FIG5, the farthest edge point of the first sealing part 1 in the vertical direction of the vehicle body is also the lowest point of the first sealing part 1 in the Z-axis direction, which can be located at the connection position between the thinning section 12 and the abutment section 13; moreover, in FIG5, for the window sealing strip 100 and window glass 600 on the right side of the vehicle body, the left side of the window sealing strip 100 and window glass 600 (i.e., the side of the window sealing strip 100 and window glass 600 located on the positive direction of the Y-axis) faces the inside of the vehicle, and the right side (i.e., the side of the window sealing strip 100 and window glass 600 located on the opposite direction of the Y-axis) faces the outside of the vehicle. In other words, in the right-side window sealing strip 100 of the vehicle body, the farthest edge point of the first sealing part 1 in the Z-axis direction and the thinning section 12 are both located on the right side of the right door window glass 600. Correspondingly, in the left-side window sealing strip 100 of the vehicle body, the farthest edge point of the first sealing part 1 in the Z-axis direction and the thinning section 12 are both located on the left side of the left door window glass 600. Compared with setting the farthest edge point of the first sealing part 1 in the Z-axis direction and the thinning section 12 on the side of the window glass 600 facing the inside of the vehicle, this embodiment can ensure that when the window sealing strip 100 and the window glass 600 are pressed and sealed, there is a larger sealing area between the first sealing part 1 and the upper outer surface of the window glass 600, resulting in a better sealing effect and preventing substances such as rainwater from entering the vehicle from the upper end of the window glass 600.
[0044] Optionally, as shown in Figure 5, in the vertical direction of the vehicle body, the distance between the center point of the thinned section 12 and the farthest edge point of the first sealing part 1 is a, and the distance between the farthest edge point of the first sealing part 1 and the outer bright strip part 510 of the decorative bright strip 500 is b, and the ratio of a to b is between 0.3 and 0.35; wherein, the outer bright strip part 510 of the decorative bright strip 500 is the part of the decorative bright strip 500 located on the side of the window glass 600 facing outward.
[0045] It should be noted that the center point of the thinning segment 12 refers to the centroid of the thinning segment 12, which is also the center of mass. In Figure 5, point P represents the center point of the thinning segment 12.
[0046] If the ratio of a to b is set too small, it means that the center point P of the thinning section 12 is close to the farthest edge point of the first sealing part 1 in the Z-axis direction. This means that the farthest edge point of the first sealing part 1 in the Z-axis direction is likely to be located on the thinning section 12, making the thinning section 12, which has relatively weak structural strength, the lowest part of the first sealing part 1. When the window glass 600 is inserted into the groove 15 along the Z-axis direction and the first sealing part 1 is squeezed, the first sealing part 1 is likely to generate a large amount of deformation in the Z-axis direction, reducing the amount of interference between the window glass 600 and the window sealing strip 100, and affecting the sealing effect. If the ratio of a to b is set too large, it means that the center point P of the thinning section 12 is far from the farthest edge point of the first sealing part 1 in the Z-axis direction. When the window glass 600 is inserted into the groove 15 along the Z-axis direction and the first sealing part 1 is squeezed, the thinning section 12 is prone to outward deformation in the opposite direction of the Y-axis in Figure 5. This causes the groove wall of the groove 15 in the opposite direction of the Y-axis in Figure 5 to deform away from the window glass 600. As a result, the groove wall of the groove 15 in the Y-axis direction cannot be tightly attached to the surface of the window glass 600, thereby reducing the coverage area between the first sealing part 1 and the window glass 600 and reducing the sealing effect.
[0047] Therefore, in this embodiment, by setting the ratio of a to b between 0.3 and 0.35, when the window glass 600 is inserted into the groove 15 along the Z-axis direction and the first sealing part 1 is pressed, it is ensured that there is sufficient interference and coverage area between the window glass 600 and the window sealing strip 100, thereby improving the sealing effect.
[0048] Optionally, referring to Figure 5, in the direction perpendicular to the window glass 600, the distance between the center point of the thinning section 12 and the outer bright strip portion 510 of the decorative bright strip 500 is h, and the distance between the outer side surface of the window glass 600 and the outer bright strip portion 510 of the decorative bright strip 500 is H, and the ratio of h to H is between 0.3 and 0.35.
[0049] Since the farthest edge point of the first sealing part 1 in the Z-axis direction and the thinning section 12 are both located on the side of the window glass 600 facing outwards, when the door of a frameless vehicle is closed, the window glass 600 will press the first sealing part 1 in the Y-axis direction and pass the farthest edge point of the first sealing part 1 before it can be inserted into the groove 15. Based on this, if the ratio of h to H is set too small, it means that the center point P of the thinning section 12 is relatively close to the outer bright strip part 510 of the decorative bright strip 500 in the Y-axis direction. When the window glass 600 presses the first sealing part 1 in the Y-axis direction and squeezes into the groove 15, the thinning section 12 is prone to outward deformation in the opposite direction of the Y-axis in Figure 5. This causes the groove wall of the groove 15 in the opposite direction of the Y-axis in Figure 5 to deform away from the window glass 600, making it impossible for the groove wall of the groove 15 to fit tightly against the surface of the window glass 600. This reduces the coverage area between the first sealing part 1 and the window glass 600, thereby reducing the sealing effect. If the ratio of h to H is set too large, it means that the center point P of the thinning section 12 is far from the outer bright strip portion 510 of the decorative bright strip 500 in the Y-axis direction and is close to the groove 15 of the abutment section 13. When the window glass 600 presses the first sealing part 1 in the Y-axis direction, the thinning section 12 is easy to deform towards the inside of the vehicle, making the first sealing part 1 easy to be pressed by the window glass 600 to the inside of the window glass 600, causing the window glass 600 to be unable to be inserted into the groove 15.
[0050] Therefore, in this embodiment, the ratio of h to H is set between 0.3 and 0.35 to ensure that there is sufficient interference and coverage area between the window glass 600 and the window sealing strip 100, thereby improving the sealing effect; and when the window glass 600 is pressed against the first sealing part 1 along the Y-axis direction, it is ensured that the window glass 600 can be inserted into the groove 15, and that there is sufficient coverage area between the window glass 600 and the window sealing strip 100, thereby improving the sealing effect.
[0051] In practical applications, the ratio of a to b can be set between 0.3 and 0.35, and the ratio of h to H can also be set between 0.3 and 0.35. This ensures that whether the sealing is achieved by squeezing the window glass 600 into the groove 15 along the Y-axis or by inserting the window glass 600 into the groove 15 along the Z-axis, the window glass 600 can be inserted into the groove 15, and there is sufficient interference and coverage area between the window glass 600 and the window sealing strip 100, thereby improving the sealing effect.
[0052] Optionally, as shown in Figures 3 and 4, the abutting section 13 is provided with a first protrusion 131 extending along the length direction of the window sealing strip 100 on one side of the cavity 3. When the window glass 600 is inserted into the groove 15, the first protrusion 131 is located on the side of the window glass 600 facing outwards and is used to abut against the first sealing section 11. The squeezing force between the first protrusion 131 and the first sealing section 11 has a component force in the direction perpendicular to the window glass 600.
[0053] In this optional embodiment, by providing a first protrusion 131 on the side of the abutment section 13 located in the cavity 3, the first protrusion 131 is located on the side of the groove 15 near the first sealing section 11 (or the side near the outside of the vehicle), so that after the window glass 600 is inserted into the groove 15, the first protrusion 131 is located on the side of the window glass 600 facing the outside of the vehicle, and the abutment section 13 can press against the first sealing section 11 at the first protrusion 131 to further enhance the sealing effect. Furthermore, by setting the compressive force between the first protrusion 131 and the first sealing section 11 to have a component force in the direction perpendicular to the window glass 600, when the first protrusion 131 abuts against the first sealing section 11, the first protrusion 131 can apply a compressive force in the Y-axis direction to the first sealing section 11, so that the first sealing section 11 and the outer bright strip portion 510 of the decorative bright strip 500 abut tightly in the Y-axis direction, thereby enabling the window sealing strip 100 to achieve double sealing in both the Z-axis and Y-axis directions, enhancing the sealing effect.
[0054] In addition, the first protrusion 131 can also enhance the structural strength of the abutment section 13, so as to further prevent the first sealing part 1 from undergoing large Z-axis deformation when it is squeezed by the window glass 600, thereby improving the amount of interference between the window glass 600 and the window sealing strip 100 and the sealing performance.
[0055] Optionally, as shown in Figures 3 and 4, the first sealing section 11 is provided with a plurality of second protrusions 112 extending along the length direction of the window sealing strip 100 on one side of the cavity 3, and at least one of the plurality of second protrusions 112 is used to abut against the first protrusion 131 when the window glass 600 is inserted into the groove 15.
[0056] In this optional embodiment, the second protrusion 112 is configured such that the first protrusion 131 and the first sealing section 11 form approximately point-to-point contact, resulting in a smaller friction area and less abnormal noise generated by friction, thereby reducing abnormal noise when closing the car window or door.
[0057] Optionally, as shown in Figure 3, the protrusion height of the second protrusion 112 is less than the protrusion height of the first protrusion 131.
[0058] If the protrusion heights of the second protrusion 112 and the first protrusion 131 are set to be the same small, the distance between the second protrusion 112 and the first protrusion 131 will be large, and when the window glass 600 is inserted into the groove 15, the second protrusion 112 and the first protrusion 131 may not make contact. If the protrusion heights of the second protrusion 112 and the first protrusion 131 are set to be the same large, the distance between the second protrusion 112 and the first protrusion 131 will be small, and when the window glass 600 presses against the first sealing part 1 along the Y-axis, the abutting force between the second protrusion 112 and the first protrusion 131 will be large, thus hindering the window glass 600 from sliding into the groove 15 and affecting the sealing effect of the window sealing strip 100.
[0059] Therefore, in this optional embodiment, by setting the protrusion height of the second protrusion 112 to be less than the protrusion height of the first protrusion 131, the second protrusion 112 and the first protrusion 131 can form an abutment during the process of inserting the window glass 600 into the groove 15, and the window glass 600 can be inserted into the groove 15. At the same time, the larger first protrusion 131 can more effectively enhance the structural strength of the abutment section 13, thereby ensuring the sealing between the window glass 600 and the window sealing strip 100.
[0060] Optionally, as shown in Figure 3, the second sealing section 14 has a first sealing protrusion 141 extending along the length of the window sealing strip 100 on one side outside the cavity 3. The first sealing protrusion 141 is positioned below the inner bright strip portion 520 of the decorative bright strip 500 and abuts against the inner bright strip portion 520 for sealing. The inner bright strip portion 520 of the decorative bright strip 500 is the portion of the decorative bright strip 500 facing the interior of the window glass 600. In this way, the first sealing protrusion 141 seals the gap between the first sealing portion 1 and the inner bright strip portion 520 on the inner side of the window glass 600, improving the sealing effect of the window sealing strip 100.
[0061] Optionally, as shown in Figure 3, the second sealing part 2 has a second sealing protrusion 21 extending along the length of the window sealing strip 100 on the side outside the cavity 3. The second sealing protrusion 21 is used to insert into the sealing slot 530 on the outer bright strip portion 510 of the decorative bright strip 500; wherein, the outer bright strip portion 510 of the decorative bright strip 500 is the part of the decorative bright strip 500 facing outwards from the window glass 600. In this way, the gap between the first sealing part 1 and the outer bright strip portion 510 is sealed on the outside of the window glass 600 by utilizing the second sealing protrusion 21, thereby improving the sealing effect of the window sealing strip 100.
[0062] Optionally, as shown in Figure 3, the second sealing section 14 is provided with a first sealing protrusion 141, and the second sealing part 2 is provided with a positioning protrusion 22 on the side outside the cavity 3. The positioning protrusion 22 and the first sealing protrusion 141 form a positioning groove 4, and the groove wall of the positioning groove 4 is used for the inner bright strip part 520 to abut. In this way, during assembly, the free end of the inner bright strip part 520 of the decorative bright strip 500 can be inserted into the positioning groove 4 to achieve the positioning and installation of the window sealing strip 100, improving the convenience of assembly. Moreover, by abutting the inner bright strip part 520 with the groove wall of the positioning groove 4, the sealing effect between the first sealing part 1 and the inner bright strip part 520 is further improved.
[0063] This utility model provides a vehicle including the window sealing strip 100 as described above.
[0064] The beneficial effects of the vehicle in this embodiment are the same as those of the window sealing strip 100 described above, and will not be repeated here.
