Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to door water-cutting components, doors, and vehicles. Background Technology

[0002] Frameless doors abandon the fixed window frame structure of traditional doors, resulting in a more streamlined vehicle shape and a significantly improved overall quality, making them popular with consumers who seek individuality and a premium experience. As a core component ensuring the normal operation of the door windows, the frameless door window regulator is crucial for maintaining the overall performance and quality of the frameless door; its importance cannot be overstated.

[0003] To accommodate the lack of sheet metal window frames above the window sill in frameless car doors, the window regulator is pre-bent in whole or in part. By changing the stress state of the glass during the lifting process, it meets the functional requirements of the frameless car door window lifting, allowing the glass to better fit the car body when closed, improving the door's sealing performance and sound insulation, while also ensuring the stability of the window lifting to a certain extent.

[0004] The pre-bending design of the glass significantly increases the compression of the inner water-cutting shear, especially when the door is open. This excessive compression due to the pre-bending causes excessive pressure between the glass and the inner water-cutting shear, resulting in significantly increased friction during window operation. This not only easily causes abnormal noises, affecting vehicle quality and passenger comfort, but also accelerates the wear of the inner water-cutting shear, reducing its sealing performance and lifespan. This can lead to potential problems such as increased interior noise and leaks, severely damaging the vehicle's overall performance and reliability. Furthermore, with prolonged use and increased mileage, excessive wear of the inner water-cutting shear may further exacerbate window operation problems such as jamming and abnormal noises, increasing maintenance costs and after-sales service burden, which is detrimental to the long-term development and brand image of automakers. Utility Model Content

[0005] Therefore, it is necessary to provide a door water cutter assembly, door, and vehicle to address the problem of abnormal noise caused by excessive pressure on the inner water cutter during the lifting and lowering of frameless car door windows.

[0006] A door water-cutting assembly includes a support plate, an inner water-cutting section, and a limiting assembly. The inner water-cutting section includes a main body and a lip portion. The main body is connected to the support plate, and the lip portion protrudes from the end face of the main body away from the support plate. The limiting assembly is connected to the support plate and includes an abutment portion that partially protrudes from the support plate. The abutment portion and the lip portion are located on the same side of the support plate, and the length of the abutment portion protruding from the support plate is adjustable. The length of the abutment portion protruding from the support plate is less than the length of the lip portion protruding from the support plate when no force is applied, and the length of the abutment portion protruding from the support plate is not less than the thickness of the main body.

[0007] In one embodiment, the inner water-cutting extension is provided, and the limiting component is located on one side of the inner water-cutting extension direction.

[0008] In one embodiment, the limiting component includes a fixing member and a moving member. The fixing member is fixedly connected to the support plate, and the moving member can move along its own axial direction and then be fastened to the fixing member. One end of the moving member protrudes from the fixing member to form the abutment portion.

[0009] In one embodiment, the movable member and the fixed member are threadedly connected, and the movable member includes at least one force-bearing surface for driving the movable member to rotate.

[0010] In one embodiment, the limiting component further includes a cover detachably connected to the fixing member, the fixing member being at least partially located on the side of the support plate opposite to the lip portion, and the cover covering the end of the fixing member away from the abutment portion, and the cover and the fixing member having a circumferential sealing fit.

[0011] In one embodiment, the end face of the abutting portion away from the support plate is the abutting surface, and the connecting surface between the abutting surface and the peripheral surface of the abutting portion is an arc-shaped surface.

[0012] In one embodiment, the abutment portion can move a distance of no more than 6 mm along its own axial direction.

[0013] In one embodiment, the abutment portion is made of polyoxymethylene resin material.

[0014] A vehicle door includes a door water-cutting assembly as described in any of the above embodiments, and also includes a liftable glass, wherein the abutment portion is located on one side of the theoretical lifting path of the glass, and the abutment portion abuts against the glass during the lifting process to interfere with the actual lifting path of the glass, wherein the actual lifting path of the glass is offset by 2mm to 4mm relative to the theoretical lifting path of the glass.

[0015] A vehicle includes a door as described in the above embodiments, and a body having an A-pillar, the door being rotatably connected to the body, the limiting assembly being located at the end of the inner water-cutting section away from the A-pillar.

[0016] The door water-cooling component provided in the above solution, by setting a limiting component on one side of the inner water-cooling, and through the abutment part protruding from the support plate in the limiting component, ensures that the glass first contacts the lip of the inner water-cooling during the glass raising and lowering process. The abutment part acts as a support when the glass exerts excessive pressure on the inner water-cooling, thus supporting the glass and preventing the glass from excessively squeezing the lip of the inner water-cooling. This reduces problems such as abnormal noise and wear caused by the glass squeezing the inner water-cooling, thereby improving the sound quality of glass raising and lowering. It can also prevent the glass from shaking when the door is opened. At the same time, the length of the abutment part protruding from the support plate can be adjusted to meet the different needs of different vehicles. Individual fine-tuning can be performed after mass production to optimize the support strength of the abutment part, maximizing the sound quality of glass raising and lowering. It can also be used to adapt to the needs of different periods during long-term vehicle use by adjusting the length of the abutment part. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0033] One embodiment of this application provides a vehicle, which can be of any type and any drive configuration, without limitation. The vehicle includes a door 10 as described in any of the following embodiments, and also includes a body with A-pillars, wherein the A-pillars are pillars on both sides of the windshield 200, located at the front of the vehicle, between the windshield 200 and the front door 10. The door 10 is rotatably connected to the body. The limiting component 130 is located at the end of the inner water cutter 120 away from the A-pillar. This is related to the degree of compression of the inner water cutter 120 at different positions after the glass 200 is pre-bent. In this embodiment, after the glass 200 is pre-bent, the end of the inner water cutter 120 away from the A-pillar is subjected to more severe compression during the lifting and lowering process. Therefore, the limiting component 130 is located at the end of the inner water cutter 120 away from the A-pillar, but this is not a limitation.

[0034] In some embodiments, the vehicle body also includes a B-pillar, which is spaced apart from the A-pillar. The B-pillar is located on the side of the vehicle, between the front door 10 and the rear door 10, and is a key component of the side structure of the vehicle body. In this case, the door 10 is rotatably connected between the A-pillar and the B-pillar, and the limiting component 130 described below is located at the end of the inner water cutter 120 near the B-pillar.

[0035] See Figure 1 , Figure 1 A schematic diagram of the structure of a car door 10 according to an embodiment of this application is shown. The car door 10 provided in this application can be applied to the above-mentioned vehicle. The car door 10 includes a car door water cutter assembly 100 as described in any of the following embodiments, and also includes a liftable glass 200, wherein the glass 200 may be partially or entirely pre-bent, or it may be a conventional glass 200, without limitation.

[0036] like Figure 1 and Figure 2 As shown, the door 10 also includes an interior trim panel 300 and an exterior trim panel 400. The exterior trim panel 400 is located on the outer side of the glass 200, and the interior trim panel 300 is located on the inner side of the glass 200. Both are used to beautify the door 10. Figure 1 and Figure 2 In the middle, due to the obstruction of the interior panel 300, the following support plate 110 is not numbered.

[0037] Combination Figure 2 and Figure 3 As shown, the limiting component 130 is located on one side of the theoretical lifting path of the glass 200. The theoretical lifting path refers to the lifting path of the glass 200 in theory, without the limiting component 130 in action. (In conjunction with...) Figure 3 As shown, the limiting component 130 abuts against the glass 200 during the lifting and lowering process to interfere with the actual lifting and lowering path of the glass 200. It can be understood that the actual lifting and lowering path refers to the path of the glass 200 lifting and lowering under the action of the limiting component 130.

[0038] exist Figure 2In this diagram, the glass 200 in the actual lifting path (the lifting path after interference from the limiting component 130) is indicated by a dashed line, while the glass 200 in the theoretical lifting path (the lifting path without interference from the limiting component 130) is indicated by a solid line. This is for illustrative purposes only and is not intended to be limiting. In this embodiment, the actual lifting path of the glass 200 is offset by 2mm to 4mm from the theoretical lifting path of the glass 200. Due to differences in vehicle models or the material or structure of the inner water cutter 120 in the door water cutter assembly 100 described below, the length of the main body portion 121 of the limiting component 130 protruding from the inner water cutter 120 is not necessarily linearly related to the interference of the limiting component 130 on the lifting path of the glass 200. In practical applications, the interference amount of the lifting path of the glass 200 can be experimentally compared based on different lengths of the limiting component 130 protruding from the support plate 110, and then the length of the abutment portion 1321 protruding from the main body portion 121 corresponding to the interference amount of the limiting component 130 on the lifting path of the glass 200 being 2mm to 4mm can be selected.

[0039] Combination Figure 4 As shown, Figure 4 A schematic diagram of a door water-cutting assembly 100 according to an embodiment of this application is shown. This application provides a door water-cutting assembly 100 that can be applied to the aforementioned door 10. Figure 4 As shown, the door water cutter assembly 100 includes a support plate 110, an inner water cutter 120, and a limiting assembly 130. Exemplarily, in this embodiment, the support plate 110 is a sheet metal door 10.

[0040] Combination Figure 3 and Figure 5 As shown, the inner water cutter 120 includes a main body 121 and a lip portion 122. The main body 121 is connected to the support plate 110. In this embodiment, the main body 121 has a bent structure and covers the top of the support plate 110, but this is not a limitation. Figure 3 and Figure 5 As shown, the lip portion 122 protrudes from the end face of the main body portion 121 away from the support plate 110, as... Figure 2 and Figure 3 As shown, the glass 200 is located on the side of the support plate 110 facing the lip 122. During the lifting and lowering of the glass 200, the glass 200 will squeeze the lip 122 and cause the lip 122 to deform.

[0041] like Figure 3 As shown, in this embodiment, the door water-cutting assembly 100 also includes an outer water-cutting 140. During the lifting and lowering of the glass 200, the outer water-cutting 140 and the inner water-cutting 120 are located on both sides of the glass 200 and are in close contact with the glass 200, thereby achieving a sealing and waterproofing effect.

[0042] like Figure 3 and Figure 5 As shown, the limiting component 130 is connected to the support plate 110, and the limiting component 130 includes an abutment portion 1321 that partially protrudes from the support plate 110. The abutment portion 1321 and the lip portion 122 are located on the same side of the support plate 110, and the length of the abutment portion 1321 protruding from the support plate 110 is adjustable. The length of the abutment portion 1321 protruding from the support plate 110 is less than the length of the lip portion 122 protruding from the support plate 110 when no force is applied, so as to avoid the abutment portion 1321 being larger than the length of the lip portion 122 and interfering with the sealing and waterproofing effect of the inner water cutter 120. Figures 3 to 5 As shown, the length of the abutment portion 1321 protruding from the support plate 110 is not less than the thickness of the main body portion 121, so that during the lifting and lowering process of the glass 200, the glass 200 first contacts the lip portion 122 of the inner water cutter 120. The abutment portion 1321 plays a supporting role when the glass 200 over-presses the inner water cutter 120, so as to support the glass 200 and avoid the glass 200 excessively pressing the lip portion 122 of the inner water cutter 120, thereby reducing the lifting and lowering noise and wear caused by the glass 200 pressing the inner water cutter 120, thereby improving the sound quality of the lifting and lowering of the glass 200, and also preventing the glass 200 from shaking when opening the door.

[0043] The length of the abutment portion 1321 protruding from the support plate 110 is adjustable, allowing it to be applied to different needs of different vehicles. Individual fine-tuning after mass production allows for personalized optimization of the support strength of the abutment portion 1321, maximizing the sound quality of the glass 200's lifting and lowering. It can also be used to adapt to different needs during long-term vehicle use by adjusting the length of the abutment portion 1321. For example, as usage time increases, the inner water cutter 120's performance may change due to wear and aging, resulting in changes in deformation when squeezed by the glass 200. If the length of the abutment portion 1321 interferes with the sealing of the inner water cutter 120, its length can be adjusted to accommodate repeated use of the inner water cutter 120.

[0044] In one embodiment, the abutment part 1321 is made of polyoxymethylene resin material, which has excellent wear resistance and good self-lubricating properties, and can be used for more than 200 lifting and lowering of the glass 200, thereby avoiding abnormal noise caused by friction between the glass 200 and the limiting component 130.

[0045] In one embodiment, the distance that the abutment portion 1321 can move along its own axial direction is no more than 6mm, so as to avoid the abutment portion 1321 being able to move too far in the axial direction of the moving member 132, which would affect the sealing effect of the inner water cutter 120 and the lifting and lowering of the glass 200.

[0046] like Figure 1As shown, in one embodiment, the inner water cutter 120 extends, and the limiting component 130 is located on one side of the extension direction of the inner water cutter 120. In this embodiment, the extension direction of the inner water cutter 120 is consistent with the front-rear direction of the vehicle. In this embodiment, in the front-rear direction, the limiting component 130 is located on the rear end side of the inner water cutter 120, but this is not a limitation, and the limiting component 130 may also be located on the front end side of the inner water cutter 120.

[0047] like Figures 4 to 6 As shown, in one embodiment, the end face of the inner water cutter 120 near the limiting component 130 is recessed with a relief groove 123 to prevent the inner water cutter 120 from interfering with the installation of the limiting component 130 and to prevent the inner water cutter 120 from being too short and affecting the seal. In this embodiment, the portions of the inner water cutter 120 located on both sides of the support plate 110 are respectively provided with relief grooves 123.

[0048] like Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the limiting component 130 includes a fixing member 131 and a moving member 132. The fixing member 131 is fixedly connected to the support plate 110, and the moving member 132 can move along its own axial direction and then be fastened to the fixing member 131. One end of the moving member 132 protrudes from the fixing member 131 to form an abutment portion 1321, thereby making the length of the abutment portion 1321 protruding from the support plate 110 adjustable. In other embodiments, the moving member 132 itself can also be configured as a telescopic structure.

[0049] like Figure 7 As shown, in one embodiment, the movable member 132 and the fixed member 131 are threaded together, as... Figure 8 As shown, the movable member 132 includes at least one force-bearing surface 1323, which is used to drive the movable member 132 to rotate. When the movable member 132 rotates, under the action of the thread, the movable member 132 will move relative to the fixed member 131 along the axial direction of the movable member 132. In this embodiment, a groove 1324 is recessed on the end face of the movable member 132 away from the abutment portion 1321. The groove 1324 has a polygonal structure and includes multiple force-bearing surfaces 1323, which facilitates applying force to the movable member 132 to drive it to rotate. In other embodiments, the groove 1324 may also be an elliptical structure or the like. In other embodiments, the end of the movable member 132 away from the abutment portion 1321 may also have a prism structure, so that the wall of the prism is the force-bearing surface 1323, and the movable member 132 can be driven to rotate by applying force to the force-bearing surface 1323 with a wrench or the like.

[0050] like Figure 6 and Figure 7As shown, in one embodiment, the limiting component 130 further includes a cover 133, which is detachably connected to the fixing member 131. The fixing member 131 is at least partially located on the side of the support plate 110 opposite to the lip portion 122, and the cover 133 covers the end of the fixing member 131 away from the abutment portion 1321. The cover 133 and the fixing member 131 are in a circumferential sealing fit to achieve a waterproof effect. In this embodiment, as... Figure 7 and Figure 8 As shown, the circumferential surface of the fastener 131 is provided with a protruding strip 1311, and the protruding strip 1311 and the inner wall surface of the cover 133 are interference-fitted to achieve a sealed connection between the fastener 131 and the cover 133.

[0051] like Figure 5 and Figure 7 As shown, in one embodiment, the end face of the abutment portion 1321 away from the support plate 110 is the abutment surface 1322, and the connecting surface between the abutment surface 1322 and the peripheral surface of the abutment portion 1321 is an arc-shaped surface, so that the contact between the glass 200 and the limiting component 130 is smoother during the lifting and lowering process.

[0052] The door water-cutting assembly 100 provided in the above solution has a limiting assembly 130 on one side of the inner water-cutting 120. Through the abutment portion 1321 protruding from the support plate 110 in the limiting assembly 130, during the lifting and lowering of the glass 200, the glass 200 first contacts the lip 122 of the inner water-cutting 120. The abutment portion 1321 acts as a support when the glass 200 over-presses the inner water-cutting 120, thus supporting the glass 200 and preventing excessive pressure from the glass 200 on the lip 122 of the inner water-cutting 120, thereby reducing the pressure exerted by the glass 200 on the inner water-cutting 120. This design addresses issues such as squeezing causing abnormal noises and wear during lifting, improving the sound quality of the glass 200 during lifting. It also prevents the glass 200 from shaking when the door is opened. Furthermore, the length of the abutment part 1321 protruding from the support plate 110 can be adjusted to meet the different needs of different vehicles. Individual fine-tuning can be performed after mass production to optimize the support strength of the abutment part 1321, maximizing the sound quality of the glass 200 lifting. It can also be used to adapt to different needs during long-term vehicle use by adjusting the length of the abutment part 1321.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
