Description

Technical Field

[0001] This utility model relates to the field of automotive sealing technology, specifically to an external water cutter and an automobile. Background Technology

[0002] The exterior water-resistant sealing strip for car doors (hereinafter referred to as exterior water-resistant strip) is an automotive component that combines functional and aesthetic requirements. It is installed on the outside of car doors and windows to achieve both sealing between the door and window glass and decorative functions.

[0003] In the existing technology, in order to achieve the sealing performance between the car door and the window glass, and to enable the window glass to be raised and lowered freely, as well as to absorb energy, reduce vibration and reduce noise when closing the door and driving on bumpy roads, the sealing part of the outer water cutter mostly adopts a double lip structure.

[0004] However, during the raising and lowering of automotive side windows, if the outer bevel lip exerts too much sealing force, it will cause high resistance to the window's movement, resulting in slow window operation and potentially causing abnormal noises during operation. Conversely, if the outer bevel lip exerts too little sealing force, it will lead to reduced sealing performance and even water or air leaks. Traditional outer bevel lip compression loads are not adjustable, making it impossible to address both of these issues simultaneously. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the compressive load of the traditional external water-cutting lip is not adjustable in the prior art, thereby providing an external water-cutting lip for automobiles.

[0006] To solve the above-mentioned technical problems, this utility model provides an external water cutter, including: a body, a lip assembly, and an inflation device. The lip assembly is disposed on the side of the body near the vehicle window glass, and the lip assembly is provided with a first water-cutting lip for sealing contact with the vehicle window glass. The first water-cutting lip is configured as a bubble-like structure with a cavity. The inflation device is disposed on the body, and the air blowing end of the inflation device is connected to the cavity of the first water-cutting lip.

[0007] In use, when the car window is in the open position, the air inflator vents the cavity of the first water-cutting lip to reduce its water-cutting sealing force, preventing excessive resistance that could cause difficulty in raising and lowering the window or abnormal noises. When the car window is in the raised position, the air inflator inflates the cavity of the first water-cutting lip to increase its water-cutting sealing force and ensure a good seal. This invention provides an external water-cutting lip that solves the problem of non-adjustable compressive load on traditional external water-cutting lips in existing technologies.

[0008] Optionally, the lip assembly also includes a second water-cutting lip parallel to the first water-cutting lip on the side near the window glass, the end of which is used for sealing contact with the window glass. With this arrangement, the second water-cutting lip and the first water-cutting lip work together to improve the sealing effect on the window glass.

[0009] Optionally, the second water-cutting lip is configured as a bubble-like structure with a cavity, and the cavity of the second water-cutting lip is connected to the air-blowing end of the inflation device. With this configuration, when the vehicle window is in the un-raised state, the inflation device vents the cavities of the first and second water-cutting lips, reducing the water-cutting sealing force of the first and second water-cutting lips and preventing excessive resistance that could cause difficulty in raising and lowering the vehicle window or abnormal noise during the raising and lowering process. When the vehicle window is in the raised state, the inflation device inflates the cavities of the first and second water-cutting lips, increasing the water-cutting sealing force of the first and second water-cutting lips and ensuring a good seal.

[0010] Optionally, the upper sidewall of the first water-cutting lip is configured as a convex arc-shaped edge, and the lower sidewall of the first water-cutting lip is configured as an inclined edge; the upper sidewall of the second water-cutting lip is configured as a concave arc-shaped edge, and the lower sidewall of the second water-cutting lip is configured as an inclined edge. With these configurations, the first water-cutting lip forms a sealed bubble-like structure on the body through its arc-shaped upper sidewall and inclined lower sidewall, and the second water-cutting lip also forms a sealed bubble-like structure on the body through its arc-shaped upper sidewall and inclined lower sidewall. The sealing force of the first and second water-cutting lips can be adjusted using an inflation device.

[0011] Optionally, the second water-cutting lip is configured as an inclined sheet-like structure. With this configuration, the second water-cutting lip, through its sheet-like structure, cooperates with the first water-cutting lip, improving the sealing effect between the lip assembly and the window glass.

[0012] Optionally, the upper sidewall of the first water-cutting lip is configured as a concave arc-shaped structure, and the lower sidewall of the first water-cutting lip is configured as a bent structure. With the above configuration, the first water-cutting lip forms a sealed bubble-like structure on the body through the upper and lower sidewalls, allowing for adjustment of the sealing force via an inflation device. Simultaneously, the combination of the concave arc-shaped upper sidewall and the upwardly bent lower sidewall makes it easier for the first water-cutting lip to deform.

[0013] Optionally, the main body is provided with an arc-shaped mounting groove, and a snap-fit ​​component is provided on the inner side wall of the mounting groove. The snap-fit ​​component is used to snap and fix it to the sheet metal part of the car door. With the above configuration, the main body is installed on the sheet metal of the car door through the arc-shaped mounting groove, and the cross-section is fixed by snapping with the sheet metal part of the car door through the snap-fit ​​component on the inner side wall of the mounting groove.

[0014] Optionally, a limiting protrusion is provided on the body. This limiting protrusion prevents the sheet metal parts of the door from dislodging from the mounting groove of the body.

[0015] Optionally, a decorative strip is provided on the main body. This decorative strip serves to conceal installation gaps and improve aesthetics.

[0016] This utility model provides an automobile, including: a body and an outer waterstop as described in any of the above-described embodiments, wherein a door is provided on the body, and the body of the outer waterstop is disposed on the sheet metal of the door. Due to the use of the aforementioned outer waterstop, it possesses any of the advantages described above. Attached Figure Description

[0023] 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.

[0024] This embodiment provides an external water-cutting structure capable of adjusting the water-cutting sealing force for sealing between car doors and windows.

[0025] like Figure 1-4 The illustration shows a specific implementation of an external water-cutting device provided in this embodiment, comprising: a body 1, a lip assembly, and an inflation device. The lip assembly is disposed on the side of the body 1 near the vehicle window glass 7. The lip assembly is provided with a first water-cutting lip 2 for sealing contact with the vehicle window glass 7. The first water-cutting lip 2 is configured as a bubble-like structure with a cavity. The inflation device is disposed on the body 1, and the air blowing end of the inflation device communicates with the cavity of the first water-cutting lip 2.

[0026] In use, when the window glass 7 is in the un-raised position, the air inflator vents the cavity of the first water-cutting lip 2, reducing the water-cutting sealing force of the first water-cutting lip 2 and preventing excessive resistance that could cause difficulty in raising and lowering the window glass 7 or abnormal noise during raising and lowering. When the window glass 7 is in the raised position, the air inflator inflates the cavity of the first water-cutting lip 2, increasing the water-cutting sealing force of the first water-cutting lip 2 and ensuring a good seal. The external water-cutting lip provided in this embodiment solves the problem of the non-adjustable compressive load of traditional external water-cutting lip lips in the prior art.

[0027] Specifically, the inflation device includes a controller 9 and an air pump 8. The controller 9 is connected to a power source, and the air pump 8 is connected to the controller 9. The blowing end of the air pump 8 is connected to the cavity of the first water-cutting lip 2.

[0028] Specifically, the lip assembly is configured as a flexible structure, and the body 1 includes a rigid support and EPDM rubber wrapped around the outside of the support.

[0029] Specifically, when the window glass 7 is not in the raised state, the sealing force of the first water-cutting lip 2 is 3-5N / 100mm, and when the window is in the raised state, the sealing force of the first water-cutting lip 2 is 10-12N / 100mm.

[0030] like Figure 3 , Figure 4 As shown, in the external water-cutting lip assembly provided in this embodiment, a second water-cutting lip 3 is also provided on the side of the lip assembly near the window glass 7, parallel to the first water-cutting lip 2. The end of the second water-cutting lip 3 is used for sealing contact with the window glass 7. The second water-cutting lip 3 and the first water-cutting lip 2 cooperate to improve the sealing effect on the window glass 7. Alternatively, as an alternative implementation, the second water-cutting lip 3 can be omitted, and sealing can be achieved solely through the first water-cutting lip 2.

[0031] like Figure 3 As shown, in the external water-cutting device provided in this embodiment, the second water-cutting lip 3 is configured as a bubble-like structure with a cavity, and the cavity of the second water-cutting lip 3 is connected to the air blowing end of the inflation device. When the window glass 7 is in the un-raised state, the inflation device vents the cavities of the first water-cutting lip 2 and the second water-cutting lip 3, reducing the water-cutting sealing force of the first water-cutting lip 2 and the second water-cutting lip 3, preventing excessive resistance from causing difficulty in raising and lowering the window glass 7 and abnormal noise during raising and lowering; when the window glass 7 is in the raised state, the inflation device inflates the cavities of the first water-cutting lip 2 and the second water-cutting lip 3, increasing the water-cutting sealing force of the first water-cutting lip 2 and the second water-cutting lip 3, ensuring the sealing effect.

[0032] Specifically, such as Figure 1 , Figure 2 As shown, the cavities of the first water-cutting lip 2 and the second water-cutting lip 3 are provided with built-in air nozzles 10 through water-cutting seals, and the air nozzles 10 are connected to the air pump 8.

[0033] like Figure 3As shown, in the external water-cutting lip provided in this embodiment, the upper sidewall of the first water-cutting lip 2 is configured as a convex arc-shaped edge, and the lower sidewall of the first water-cutting lip 2 is configured as an inclined edge; the upper sidewall of the second water-cutting lip 3 is configured as a concave arc-shaped edge, and the lower sidewall of the second water-cutting lip 3 is configured as an inclined edge. The first water-cutting lip 2 forms a sealed bubble-like structure on the body 1 through the arc-shaped upper sidewall and the inclined lower sidewall, and the second water-cutting lip 3 forms a sealed bubble-like structure on the body 1 through the arc-shaped upper sidewall and the inclined lower sidewall. The sealing force of the first water-cutting lip 2 and the second water-cutting lip 3 can be adjusted by the inflation device. In addition, as an alternative embodiment, the upper sidewall of the first water-cutting lip 2 can also be configured as an inclined edge.

[0034] like Figure 4 As shown, in the external water-cutting center provided in this embodiment, the second water-cutting lip 3 is configured as an inclined sheet-like structure. The sheet-like structure of the second water-cutting lip 3, in conjunction with the first water-cutting lip 2, improves the sealing effect between the lip assembly and the window glass 7. Alternatively, as an alternative embodiment, the second water-cutting lip 3 can also be configured as a bubble-like structure.

[0035] like Figure 4 As shown, in the external water-cutting lip provided in this embodiment, the upper sidewall of the first water-cutting lip 2 is configured as a concave arc-shaped structure, and the lower sidewall of the first water-cutting lip 2 is configured as a bent structure. The first water-cutting lip 2 forms a sealed bubble-like structure on the body 1 through the upper and lower sidewalls, and the sealing force can be adjusted by the inflation device; at the same time, the upper sidewall of the concave arc-shaped structure and the lower sidewall bent upward cooperate to make the first water-cutting lip 2 more easily deformable. In addition, as an alternative embodiment, the upper sidewall of the first water-cutting lip 2 can also be configured as an inclined straight edge.

[0036] like Figure 3 , Figure 4 As shown, in the external water cutter provided in this embodiment, the main body 1 is provided with an arc-shaped mounting groove, and a snap-fit ​​member 4 is provided on the inner side wall of the mounting groove. The snap-fit ​​member 4 is used to snap and fix with the sheet metal of the car door. The main body 1 is mounted on the sheet metal of the car door through the arc-shaped mounting groove, and the snap-fit ​​member 4 on the inner side wall of the mounting groove snaps and fixes the cross-section with the sheet metal of the car door. Specifically, the snap-fit ​​member 4 is set with an upward-curved tooth-like structure. In addition, as an alternative embodiment, the mounting groove can also be set as a square groove according to the sheet metal of the car door.

[0037] like Figure 3 , Figure 4As shown in the embodiment, in the external water cutter provided, the body 1 is provided with a limiting protrusion 5. The limiting protrusion 5 can prevent the sheet metal parts of the door from falling out of the mounting groove of the body 1.

[0038] like Figure 3 , Figure 4 As shown, in the external water cutter provided in this embodiment, the main body 1 is provided with a decorative strip 6. The decorative strip 6 can cover the installation gap and improve the aesthetics. Specifically, the main body 1 is provided with a snap-fit ​​protrusion, and the decorative strip 6 is provided with a snap-fit ​​groove that cooperates with the snap-fit ​​protrusion.

[0039] How to use: like Figure 1 As shown, the external water cutter provided in this embodiment, when the car window glass 7 is in the un-raised state, vents air from the cavity of the first water cutter lip 2 through the inflation device, reducing the water cut sealing force of the first water cutter lip 2, preventing excessive resistance from causing difficulty in raising and lowering the car window glass 7 and abnormal noise during raising and lowering; when the car window glass 7 is in the raised state, the cavity of the first water cutter lip 2 is inflated through the inflation device, increasing the water cut sealing force of the first water cutter lip 2 and ensuring the sealing effect.

[0040] In addition, this embodiment also provides a car, including: a car body and an external water cutter as described in the above embodiments. A door is provided on the car body, and the body 1 of the external water cutter is disposed on the sheet metal of the door. By employing the external water cutter described in the above embodiments, a seal is achieved between the car door and the car window.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
