Description

Technical Field

[0001] This application relates to the field of vehicle door technology, and in particular to a vehicle door and an automobile. Background Technology

[0002] In automotive interior design, the inner door panels, particularly the visible areas near the windowsill, are often covered with leather trim to enhance the overall quality and aesthetics of the interior. Currently, to ensure the smoothness and complete coverage of the leather trim along the window edge, the edges are typically tucked into the door glass channel and extend below the window sill. To maintain a tight seal between the door glass and the inner door, an internal water-cooling device is usually installed within the inner door glass channel. This effectively prevents rainwater, dust, and foreign objects from entering the door, ensuring a clean and dry interior environment. It also guides and cushions the window operation, reducing noise during window operation and improving passenger comfort.

[0003] However, during frequent window opening and closing, the inner water cutter needs to provide guiding force to the glass when it rises. Due to its inherent elasticity and rigidity, it exerts an upward thrust on the leather trim fabric inserted into the glass channel when it comes into contact with it. This thrust is particularly amplified when the glass channel space is limited, the leather trim fabric is not securely fastened, or the inner water cutter is worn or deformed, resulting in an uneven surface. As usage time and the number of window openings and closings increase, this thrust accumulates, easily causing the leather trim fabric to curl up, resulting in an unsightly appearance of the door. Once this happens, it not only damages the overall aesthetics of the door interior and reduces the user experience, but may also cause problems such as jamming and abnormal noises during window opening and closing, affecting the normal operation of the window lifting mechanism. Furthermore, the protruding leather trim fabric, constantly rubbing against the glass and inner water cutter, is prone to wear and tear, shortening the lifespan of the door interior components and increasing maintenance costs and the user's burden. Utility Model Content

[0004] The purpose of this application is to provide a car door and a car to address, to a certain extent, the technical problems existing in the prior art where, during frequent raising and lowering of the car door glass, the leather trim fabric is easily pushed out by the inner water cutter. This not only damages the overall aesthetics of the car door interior and reduces the user experience, but may also cause problems such as jamming and abnormal noises during the raising and lowering of the car door glass, affecting the normal operation of the glass raising and lowering mechanism. Furthermore, the pushed-out leather trim fabric is prone to wear and tear due to long-term friction with the glass and the inner water cutter, shortening the service life of the car door interior parts and increasing maintenance costs and the user's burden.

[0005] According to a first aspect of this application, a vehicle door is provided, including an inner door assembly, a door glass, and an inner water cutter. The door glass is capable of being raised and lowered in a first direction. The inner door assembly includes a decorative fabric and a door panel. The door panel is disposed on one side of the door glass in a second direction. A retaining edge extending inward toward the door panel in the first direction is provided at one end of the door panel near the door glass. The decorative fabric covers the outer side of the door panel and extends to the side of the retaining edge opposite to the door glass.

[0006] The internal water cutter includes a connecting part, a fixing part, and a sealing part. The fixing part is snapped into the door guard plate, at least a portion of the sealing part contacts the door glass, and the connecting part connects the fixing part and the sealing part.

[0007] During the lifting and lowering of the door glass, the sealing part can swing with the door glass, and the highest point of the sealing part swinging with the door glass toward the side where the door guard plate is located is defined as the extreme swing position;

[0008] In the first direction, the stop extends away from the door panel to a position beyond the limit swing position, and the first direction intersects with the second direction.

[0009] Preferably, the dimension of the portion of the flange beyond the limit swing position in the first direction is h, where h ≥ 5 mm.

[0010] Preferably, in the second direction, the minimum distance between the sealing part and the flange is a, where a ≥ 3 mm;

[0011] And / or, when the sealing part is in the extreme swing position, the included angle ∠c between the sealing part and the door glass is 13°~15°.

[0012] Preferably, the door panel further includes a first limiting rib, which is parallel to and spaced apart from the stop edge to form a first limiting groove between the stop edge and the first limiting rib.

[0013] The connecting portion extends along the first direction, and one end of the connecting portion extends into the first limiting groove.

[0014] Preferably, the inner water cutter further includes a shielding lip, one end of which in the first direction is connected to the end of the connecting portion near the door panel, and the connecting portion extends into the first limiting groove via the shielding lip;

[0015] The shielding lip has a cross-section that is an arc-shaped structure that is concave towards the side where the door glass is located along the second direction, and the outer edge of the shielding lip abuts against the stop.

[0016] Preferably, the sealing portion includes a plurality of sealing lips, which are spaced apart along the first direction;

[0017] The inner water cutter also includes support protrusions extending along the second direction, the number of which corresponds one-to-one with the number of sealing lips, and the sealing lips are connected to the connecting portion via the support protrusions;

[0018] A thinning groove is provided on the side of the connection between the support protrusion and the sealing lip facing the retaining edge.

[0019] Preferably, the inner water cutter further includes a support rib, and a support rib is provided between two adjacent support protrusions;

[0020] In the second direction, the minimum distance between the two sealing lips adjacent to the support rib and the support rib is b, where b ≥ 1 mm.

[0021] Preferably, the fixing part is disposed on the side of the connecting part facing away from the door glass in the second direction;

[0022] The door panel further includes a second limiting rib, which is disposed on the side of the first limiting rib away from the stop edge, so as to form a second limiting groove between the first limiting rib and the second limiting rib.

[0023] The fixing part is engaged in the second limiting groove.

[0024] Preferably, the fixing part is further provided with a snap-fit ​​groove, and the opening of the snap-fit ​​groove is located on the side of the snap-fit ​​groove facing away from the door panel in the first direction;

[0025] The inner door assembly also includes a door reinforcement plate and an inner door panel. The ends of the door reinforcement plate and the inner door panel near the door guard plate are attached to each other. The ends of the door reinforcement plate and the inner door panel near the door guard plate both extend into the snap-fit ​​groove and snap-fit ​​with the fixing part.

[0026] According to a second aspect of this application, an automobile is provided, including the door described in any of the above-mentioned technical solutions, and thus possesses all the beneficial technical effects of the door, which will not be repeated here.

[0027] Compared with the prior art, the beneficial effects of this application are as follows:

[0028] The door panel provided in this application features a stop that extends inward and exceeds the limit swing position of the inner water-cutting seal in a first direction, providing a stable limiting structure for the trim fabric. During the raising and lowering of the door glass, even if the inner water-cutting seal swings with the door glass and generates an upward thrust, the stop effectively prevents the trim fabric from being pushed out, avoiding problems such as decreased interior aesthetics and abnormal noise during glass raising and lowering caused by trim fabric displacement. This significantly improves the stability and reliability of the door interior. The inner water-cutting seal employs a structure of a connecting part, a fixing part, and a sealing part. The fixing part snaps into the door panel, facilitating installation and disassembly, reducing assembly difficulty and maintenance costs. The sealing part contacts the door glass and can swing flexibly, ensuring both door sealing and smooth glass raising and lowering. The effective limiting of the trim fabric by the stop reduces abnormal friction between the trim fabric and the inner water-cutting seal, thereby extending the service life of both the trim fabric and the inner water-cutting seal, and reducing the frequency and cost of replacing parts later.

[0040] The following reference Figure 1 and Figure 2 This application describes a car door and a car according to some embodiments.

[0041] See Figure 1 and Figure 2As shown, an embodiment of the first aspect of this application provides a vehicle door, which includes an inner door assembly, a door glass 3, and an inner waterstop. The door glass 3 is capable of being raised and lowered along a first direction F1. The inner door assembly includes a decorative fabric 110 and a door panel 11. The door panel 11 is disposed on one side of the door glass 3 in a second direction F2. A retaining edge 111 extending inward along the first direction F1 towards the door panel 11 is provided at one end of the door panel 11 near the door glass 3. The decorative fabric 110 covers the outer side of the door panel 11 and extends to the side of the retaining edge 111 opposite to the door glass 3. The inner waterstop includes a connecting portion 210, a fixing portion 22, and a sealing portion. The fixing portion 22 is engaged with the door panel 11, and at least a portion of the sealing portion contacts the door glass 3. The connecting portion 210 connects the fixing portion 22 and the sealing portion. During the raising and lowering of the door glass 3, the sealing portion can swing with the door glass 3. The highest point at which the sealing portion swings with the door glass 3 towards the side where the door panel 11 is located is defined as the limit swing position. In the first direction F1, the retaining edge 111 extends to the side away from the door panel 11 to a position exceeding the limit swing position.

[0042] According to the aforementioned technical features, the door panel 11 is provided with a retaining edge 111 extending inward and exceeding the limit swing position of the inner water-cutting seal in the first direction F1. This provides a stable limiting structure for the decorative fabric 110, preventing contact between the seal and the edge of the decorative fabric 110. During the lifting and lowering of the door glass 3, even if the inner water-cutting seal swings with the door glass 3 and generates an upward thrust, the retaining edge 111 can effectively prevent the decorative fabric 110 from being pushed out, avoiding problems such as decreased interior aesthetics and abnormal noise during glass lifting and lowering caused by the displacement of the decorative fabric 110, thus significantly improving the stability and reliability of the door interior. The inner water-cutting seal adopts a structure of a connecting part 210, a fixing part 22, and a sealing part. The fixing part 22 is snapped into the door panel 11, facilitating installation and disassembly, reducing assembly difficulty and maintenance costs; the sealing part contacts the door glass 3 and can swing flexibly, ensuring smooth glass lifting and lowering while maintaining the door's sealing performance. The effective limiting of the decorative fabric 110 by the baffle 111 can reduce abnormal friction between the decorative fabric 110 and the inner water cutter, thereby extending the service life of the decorative fabric 110 and the inner water cutter, and reducing the frequency and cost of replacing parts later by users.

[0043] like Figure 1 and Figure 2 The figure shows F1 as an example of the first direction F1, and F2 as an example of the second direction F2, which intersects the first direction F1. Preferably, the second direction F2 can be perpendicular to the first direction F1 to accommodate most door structures. For ease of description, the direction perpendicular to the plane defined by both the first direction F1 and the second direction F2 is defined as a third direction (not shown in the figure, i.e., ...). Figure 1 and Figure 2 (From a perspective perpendicular to the paper), the aforementioned inner water cut can be a strip-shaped structure extending along a third direction to adapt to the structure of the car window.

[0044] It should be noted that, as Figure 1 As shown in the figure, the dashed structure represents the state where the sealing part swings to its highest point along with the door glass 3 toward the side where the door guard plate 11 is located. Taking the position shown in the figure as an example, the highest point of the dashed structure can be marked as the extreme swing position.

[0045] Preferably, such as Figure 1 As shown, the dimension of the portion of the upper stop 111 in the first direction F1 that exceeds the limit swing position is h (e.g. Figure 1 As shown in the figure, where h ≥ 5mm, this provides sufficient limiting allowance for the decorative fabric 110. During frequent raising and lowering of the door glass 3, even if the inner water-cutting seal experiences significant swinging and thrust, it can effectively prevent the decorative fabric 110 from being pushed out, greatly improving the fixing effect of the decorative fabric 110 and avoiding problems such as loose interior trim and damage to aesthetics caused by displacement of the decorative fabric 110. It ensures a stable protective relationship between the baffle 111 and the inner water-cutting, reducing abnormal friction between the inner water-cutting and the decorative fabric 110 during swinging, preventing edge wear and tear of the decorative fabric 110, and also reducing wear caused by excessive friction of the inner water-cutting, extending the service life of the door interior components, and reducing maintenance costs and replacement frequency caused by component damage.

[0046] Preferably, such as Figure 1 As shown, in the second direction F2, the minimum distance between the sealing part and the retaining edge 111 is 'a', where 'a' ≥ 3mm. This ensures sufficient clearance between the sealing part and the retaining edge 111, effectively preventing interference and collision between the sealing part and the retaining edge 111 during the swinging of the door glass 3. This further reduces the probability of the sealing part contacting the decorative fabric 110 during the swinging process, further preventing the decorative fabric 110 from being pushed out by the sealing part, improving the aesthetics of the decorative edging, and reducing frictional wear between the sealing part and the decorative fabric 110. It ensures the freedom of movement of the sealing part, maintains its good sealing and guiding functions, and guarantees smooth lifting and lowering of the door glass 3.

[0047] It should be noted that, as Figure 1 As shown, when the sealing part swings with the door glass 3 up and down to the extreme swing position, at this time, the distance between the sealing part and the stop 111 in the second direction F2 is the smallest, that is... Figure 1 The value of 'a' is shown.

[0048] Preferably, such as Figure 1As shown, when the sealing part is in the extreme swing position, the included angle between the sealing part and the door glass can satisfy ∠c=13°~15°, so as to ensure the sealing between the sealing part and the door glass and the stability of the sealing part.

[0049] In an embodiment, such as Figure 1 As shown, the aforementioned door guard plate 11 may further include a first limiting rib 112, which is parallel to and spaced apart from the retaining edge 111, forming a first limiting groove between the retaining edge 111 and the first limiting rib 112. The connecting portion 210 extends along the first direction F1, with one end of the connecting portion 210 extending into the first limiting groove. Thus, the first limiting groove formed by the first limiting rib 112 and the retaining edge 111 provides precise positioning and a stable installation space for the connecting portion 210 of the aforementioned inner water cutter, improving the installation stability of the inner water cutter.

[0050] Preferably, such as Figure 1 and Figure 2 As shown, the aforementioned inner water cutter may further include a shielding lip 211. One end of the shielding lip 211 in the first direction F1 is connected to the end of the connecting portion 210 near the door panel 11. The connecting portion 210 extends into the first limiting groove via the shielding lip 211. The cross-section of the shielding lip 211 can be an arc-shaped structure recessed towards the side where the door glass 3 is located along the second direction F2. The outer edge of the shielding lip 211 abuts against the retaining edge 111. Thus, the outer edge of the arc-shaped structure recessed towards the side where the door glass 3 is located, formed by the shielding lip 211, abuts against the retaining edge 111, effectively filling the gap between the connecting portion 210 and the door panel 11, enhancing the sealing performance of the car door. When the door glass 3 is raised or lowered, the shielding lip 211 can prevent rainwater, dust, and other foreign objects from entering the interior of the car door through the gap between the connecting portion 210 and the door panel 11, avoiding damage to components caused by the intrusion of foreign objects, better protecting the glass lifting mechanism and other components inside the car door, and extending the overall service life of the car door.

[0051] Preferably, such as Figure 1 and Figure 2 As shown, the sealing part can include multiple sealing lips 23, which can be spaced apart along the first direction F1. Thus, multiple sealing lips 23 are provided in the lifting direction of the door glass 3, so that multiple seals are formed between the door glass 3 and the inner door assembly, effectively improving the sealing effect of the sealing part.

[0052] like Figure 1 and Figure 2 As shown in the figure, an example of two sealing lips 23 is shown. However, it is not limited to this. The number of sealing lips 23 can be adjusted according to the size of the connecting part 210 and the size of the door. For example, the number of sealing lips 23 can also be one, three, four or more.

[0053] It should be noted that, as Figure 1 and Figure 2 As shown in the figure, taking the orientation shown in the figure as an example, the above-mentioned extreme swing position can refer to the position of the uppermost one of the multiple sealing lips 23 swinging to the highest point.

[0054] Specifically, not shown in the figure, in its naturally extended state, the sealing lip 23 is a sheet-like structure extending along the second direction F2. When the inner water-cutting device is installed on the inner door assembly, the sealing lip 23 in its naturally extended state extends beyond the door glass 3 in the second direction F2. Thus, when the door glass 3 rises along the first direction F1, the sealing lip 23 can be pushed upward by the door glass 3, so that the lower surface of the sealing lip 23 in its naturally extended state fits against the inner wall of the door glass 3, thereby achieving a sealing effect on the side of the door glass 3 regardless of whether the door glass 3 rises or falls.

[0055] Preferably, such as Figure 1 and Figure 2 As shown, the sealing lip 23 may also include a fleece layer 231. The fleece layer 231 is attached to the lower surface of the sealing lip 23 and extends from the end of the sealing lip 23 away from the connecting portion 210 to the upper surface of the sealing lip 23. In this way, when the door glass 3 is raised or lowered, the sealing lip 23 can contact the door glass 3 through the fleece layer 231. This not only reduces friction noise between the door glass 3 and the sealing lip 23, but also the fleece layer 231 has good water absorption and cleaning properties, which can scrape off dust, liquid and other debris from the glass surface during the raising and lowering of the door glass 3, preventing debris from being brought into the car door through the door glass 3.

[0056] Preferably, such as Figure 1 and Figure 2 As shown, the inner water cutter may also include a support protrusion 213 extending along the second direction F2. The number of support protrusions 213 corresponds one-to-one with the number of sealing lips 23. The sealing lips 23 are connected to the connecting portion 210 via the support protrusions 213. Thus, by setting the support protrusions 213, the influence of the sealing lips 23 on the stability of the connecting portion 210 during the movement of the door glass 3 is effectively reduced, and the connecting portion 210 is effectively prevented from being rolled up by the sealing lips 23, which would affect the smoothness of the door glass 3's lifting and lowering, and reduce the probability of abnormal noise during the lifting and lowering of the door glass 3.

[0057] Furthermore, such as Figure 1 and Figure 2As shown, a thinning groove 214 is provided on the side of the connection between the support protrusion 213 and the sealing lip 23 facing the stop 111. This further improves the sensitivity of the sealing lip 23 to bending relative to the support protrusion 213, which not only further reduces the impact of the sealing lip 23 on the stability of the connection part 210 during the movement of the door glass 3, but also effectively reduces the obstruction of the sealing lip 23 to the rise of the door glass 3, and improves the smoothness of the rise and fall of the door glass 3.

[0058] Optionally, such as Figure 1 and Figure 2 As shown, the cross-section of the aforementioned thinning groove 214 can be semi-circular to reduce stress concentration at the connection between the support protrusion 213 and the sealing lip 23, thereby reducing the probability of breakage at the connection between the support protrusion 213 and the sealing lip 23.

[0059] Preferably, such as Figure 1 and Figure 2 As shown, the aforementioned inner water cutter may also include a support rib 24. A support rib 24 is provided between two adjacent support protrusions 213 to improve the bending strength of the connection part 210 and further reduce the probability that the connection part 210 will be warped by the sealing lip 23.

[0060] Preferably, such as Figure 1 As shown, in the second direction F2, the one of the two sealing lips 23 adjacent to the support rib 24 that is furthest from the retaining edge 111 (i.e. Figure 1 The minimum distance between the lower sealing lip 23 (one of the two sealing lips 23 shown) and the support rib 24 is b, where b ≥ 1 mm. When the sealing lip 23 adjacent to the support rib 24, the one furthest from the stop 111, rises to its highest point with the door glass 3, the distance between the sealing lip 23 furthest from the stop 111 and the support rib 24 in the second direction F2 is the minimum (i.e., ...). Figure 1 The b value shown makes b≥1mm, which effectively prevents the sealing lip 23 from colliding with the support rib 24 during the process of the two sealing lips 23 adjacent to the support rib 24, the one farther from the stop 111, rising with the door glass 3, thus reducing the frictional loss of the inner water shear itself.

[0061] In an embodiment, preferably, such as Figure 1 and Figure 2 As shown, the aforementioned inner door assembly may further include a door reinforcement plate 12, which is disposed on the side of the inner door assembly near the door glass 3 and extends along the first direction F1 to improve the support strength of the inner door assembly on the side near the door glass 3.

[0062] Preferably, such as Figure 1As shown, the side of the connecting part 210 facing away from the sealing part can abut against the door reinforcing plate 12 to improve the stability of the inner water cutter.

[0063] Preferably, such as Figure 1 and Figure 2 As shown, the aforementioned inner water cutter may also be provided with an abutment boss 212, which may be provided on the side of the connecting part 210 facing away from the door glass 3, so as to abut against the aforementioned door reinforcing plate 12 through the abutment boss 212.

[0064] In an embodiment, such as Figure 1 and Figure 2 As shown, the fixing part 22 is disposed on the side of the connecting part 210 facing away from the door glass 3 in the second direction F2. The door guard plate 11 may also include a second limiting rib 113, which is disposed on the side of the first limiting rib 112 away from the stop 111, so as to form a second limiting groove between the first limiting rib 112 and the second limiting rib 113. The fixing part 22 is engaged in the second limiting groove to achieve the snap-fit ​​fixation between the door guard plate 11 and the fixing part 22.

[0065] Preferably, such as Figure 1 and Figure 2 As shown, one end of the fixing part 22 in the second direction F2 can be connected to the connecting part 210.

[0066] Preferably, such as Figure 1 and Figure 2 As shown, buffer lips 221 can be provided on both sides of the fixing part 22 in the second direction F2. When the fixing part 22 is engaged in the second limiting groove, the buffer lips 221 press between the groove wall of the second limiting groove and the fixing part 22 to increase the engagement stability between the fixing part 22 and the second limiting groove.

[0067] Preferably, such as Figure 1 and Figure 2 As shown, the fixing part 22 may also be provided with a snap-fit ​​groove. The opening of the snap-fit ​​groove is located on the side of the snap-fit ​​groove facing away from the door guard plate 11 in the first direction F1. The end of the door reinforcing plate 12 near the door guard plate 11 can extend into the snap-fit ​​groove to improve the snap-fit ​​stability of the fixing part 22.

[0068] Optionally, the aforementioned inner door assembly may further include an inner door panel 13, which is disposed on the side of the door reinforcement plate 12 facing away from the door glass 3, to improve the support strength and stability of the inner door assembly. The ends of the door reinforcement plate 12 and the inner door panel 13 near the door guard plate 11 are fitted together, and the fitted ends of the door reinforcement plate 12 and the inner door panel 13 can extend into the aforementioned snap-fit ​​groove and engage with the fixing part 22, further increasing the snap-fit ​​stability between the fixing part 22 and the inner door assembly.

[0069] Preferably, such as Figure 1 and Figure 2 As shown, the fixing part 22 may further include a claw 222, which is disposed on the inner wall of the locking groove in the second direction F2 to further increase the locking stability between the fixing part 22 and the inner door assembly.

[0070] Preferably, such as Figure 1 and Figure 2 As shown, the aforementioned inner water cutter can be an integrally extruded part to ensure the connection stability of each part of the inner water cutter.

[0071] The second aspect of this application also provides an automobile, including the door described in any of the above embodiments, and thus possesses all the beneficial technical effects of the door, which will not be repeated here.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
