[0025] The following refers to Figure 1 and Figure 2 Describe the inner water cut and the vehicle door according to some embodiments of the present application.

[0026] See Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present application provides an inner water cut for a vehicle door. The vehicle door includes an inner door assembly and a side door glass 3, and the side door glass 3 can be lifted and lowered along a first direction F1. Among them, the inner water cut includes a flexible component and a rigid component. The rigid component includes a fixing portion 12 and a placement portion 11. The flexible component includes a connecting portion 21 and a first sealing lip 22 that fits against the side door glass 3. The placement portion 11 extends along the first direction F1. The first sealing lip 22 and the fixing portion 12 are respectively arranged on both sides of the placement portion 11 in a second direction F2. The fixing portion 12 is used for fixedly connecting with the inner door assembly. The connecting portion 21 is arranged in the middle of the placement portion 11 in the first direction F1, and the connecting portion 21 connects the fixing portion 12 and the placement portion 11. Taking the connecting portion 21 as a boundary, the placement portion 11 is divided into a first portion 111 and a second portion 112. The first portion 111, the connecting portion 21, and the fixing portion 12 enclose a clamping gap, and at least part of the inner door assembly can be inserted into the clamping gap. The first sealing lip 22 is arranged at one end of the second portion 112 away from the first portion 111, and the side of the second portion 112 facing away from the first sealing lip 22 contacts the inner door assembly. In a state where at least part of the inner door assembly is inserted into the clamping gap, at least part of the inner door assembly can apply a force away from the fixing portion 12 to the first portion 111 ( Figure 2 The solid arrow shows the direction of the force), and the second direction F2 intersects with the first direction F1.

[0027] According to the inner water cut provided by the above technical features, through the fixing effect of the fixing portion 12 and the inner door assembly, the inner water cut is fixed between the inner door assembly and the side door glass 3. In a state where at least part of the inner door assembly is inserted into the clamping gap, at least part of the inner door assembly can apply a force away from the fixing portion 12 to the first portion 111, that is, the first portion 111 deflects towards the side where the side door glass 3 is located under the action of this force. Under the action of the flexible deformation of the connecting portion 21, the second portion 112 has a tendency to deflect towards the inner door assembly side ( Figure 2The dashed arrow indicates the deflection direction), making the second part 112 more stable against the inner door assembly, effectively preventing the first sealing lip 22 from deforming under the friction of the side door glass 3 during the up and down movement of the side door glass 3, improving the connection stability between the inner water cut and the inner door assembly, and greatly reducing the probability of problems such as loosening, displacement, abnormal noise, and sealing failure of the inner water cut.

[0028] As Figure 1 and Figure 2 shown, F1 shown in the figure can be an example of the above-mentioned first direction F1, and F2 shown in the figure can be an example of the above-mentioned second direction F2, where the first direction F1 intersects with the second direction F2. Preferably, the second direction F2 is perpendicular to the first direction F1. Define the direction perpendicular to the plane determined by both the first direction F1 and the second direction F2 as the third direction, that is Figure 1 and Figure 2 the direction perpendicular to the paper plane from the perspective of

[0029] Preferably, as Figure 1 and Figure 2 shown, the above-mentioned fixing part 12 can be provided with a fixing slot, and the fixing slot can extend along the third direction.

[0030] Correspondingly, as Figure 2 shown, the above-mentioned inner door assembly can include a door reinforcement plate 43, and the door reinforcement plate 43 extends along the first direction F1 to be close to the following interior door trim panel 41. The upper end of the door reinforcement plate 43 can extend into the above-mentioned fixing slot to realize the snap-fitting fixation of the fixing part 12 and the inner door assembly. Correspondingly, as Figure 2 shown, the above-mentioned second part 112 contacts the inner door assembly via the door reinforcement plate 43.

[0031] It should be noted that the extension of the above-mentioned door reinforcement plate 43 along the first direction F1 can be understood as that the general trend of the door reinforcement plate 43 is along the first direction F1. In order to adapt to the special-shaped structure and installation structure of the vehicle door, the door reinforcement plate 43 will form protrusions or depressions along the second direction F2 at some functional or structural key points (for example, as Figure 2 shown, the part of the door reinforcement plate 43 opposite to the second part 112 bulges towards the side where the side door glass 3 is located compared to the part of the door reinforcement plate 43 extending into the above-mentioned fixing slot, so as to facilitate the abutment of the second part 112), so as to improve the support strength and functionality of the reinforcement plate. The door reinforcement plate 43 is an existing structure of the vehicle door and will not be elaborated here.

[0032] Preferably, as Figure 1 and Figure 2As shown, the cross-section of the above-mentioned fixing portion 12 can be in the shape of a Chinese character "J", one end of the Chinese character "J" is connected to the above-mentioned connecting portion 21, and the other end of the Chinese character "J" is a free end. In this way, through the structure of the Chinese character "J", the material cost of the fixing portion 12 can be effectively reduced while the structure of the above-mentioned fixing slot is formed. It not only facilitates the fixing portion 12 to extend into the gap between the interior door guard plate 41 and the door reinforcement plate 43 for clamping and fixing, but also effectively reduces the connection area between the fixing portion 12 and the connecting portion 21, improves the flexible deformation ability of the connecting portion 21, and facilitates the above-mentioned second part 112 to abut against the door reinforcement plate 43.

[0033] Preferably, if Figure 1 and Figure 2 As shown, the above-mentioned flexible component can also include a clamping protrusion 26, which is fixed to the inner wall of the fixed clamping slot. When the door reinforcement plate 43 is arranged in the fixed clamping slot, the clamping protrusion 26 abuts against the door reinforcement plate 43, so as to increase the squeezing force of the fixing part 12 on the door reinforcement plate 43 through the flexible deformation of the clamping protrusion 26, thereby improving the clamping stability of the fixing part 12 and the door reinforcement plate 43.

[0034] Preferably, if Figure 1 and Figure 2 As shown, the inner walls on both sides of the above-mentioned fixed card slot in the second direction F2 are provided with the clamping protrusions 26 to ensure the consistency of the clamping force borne by the inner walls on both sides of the fixed card slot and improve the clamping stability of the fixing part 12 and the door reinforcement plate 43.

[0035] Preferably, if Figure 1 and Figure 2 As shown, in the direction of one end of the above-mentioned locking protrusion 26 connected to the inner wall of the fixed slot pointing to the other end, the locking protrusion 26 gradually tilts toward the slot direction away from the fixed slot. Such tilting, on the one hand, facilitates the insertion of the guiding door reinforcement plate 43 into the fixed slot; on the other hand, effectively increases the resistance of the door reinforcement plate 43 from escaping the fixed slot.

[0036] It should be noted that the abutment between the clamping protrusion 26 and the door reinforcement plate 43 can be understood as the minimum distance between the clamping protrusions 26 on the inner walls on both sides of the fixed slot in the second direction F2 is less than the thickness of the part of the door reinforcement plate 43 extending into the fixed slot. In this way, when the door reinforcement plate 43 extends into the fixed slot, the clamping protrusion 26 is in a compressed state of flexible deformation, and the friction between the fixed slot and the door reinforcement plate 43 is increased through the elastic force of the clamping protrusion 26, thereby improving the clamping stability between the fixing part 12 and the door reinforcement plate 43.

[0037] Preferably, if Figure 1 and Figure 2As shown, the flexible component may further include a second covering portion 28, which may cover the free end of the "J" shape to prevent the fixing portion 12 from scratching the inner door assembly during assembly.

[0038] In an embodiment, preferably, Figure 1 and Figure 2 As shown, the above-mentioned flexible component may also include a first overlapping lip 24, which is arranged on the side of the first part 111 facing the fixed part 12, and the first overlapping lip 24 protrudes relative to the surface of the first part 111. In this way, the first overlapping lip 24 and at least a part of the above-mentioned inner door component abut against each other, so as to achieve at least a part of the above-mentioned inner door component applying a force to the first part 111 away from the fixed part 12.

[0039] Preferably, if Figure 1 and Figure 2 As shown, in the direction in which one end of the first overlapping lip 24 connected to the first part 111 points to the other end, the first overlapping lip 24 gradually tilts toward the side where the connecting portion 21 is located. Such tilting, on the one hand, is similar to the beneficial effect of the tilting of the above-mentioned snap-fit protrusion 26, which not only facilitates the insertion of at least part of the inner door assembly into the clamping gap, but also increases the resistance of at least part of the inner door assembly to detach from the clamping gap; on the other hand, under the abutment action of the first overlapping lip 24, the further away the first part 111 is from the connecting portion 21, the greater its distance from the fixing portion 12, which effectively increases the deflection amplitude of the first part 111 under the action of the abutment force, thereby increasing the deflection trend of the second part 112, and increasing the abutment force between the second part 112 and the above-mentioned door reinforcement plate 43, thereby making it more difficult for the second part 112 to detach from the door reinforcement plate 43, thereby improving the fitting stability of the second part 112 and the door reinforcement plate 43.

[0040] Preferably, the number of the first overlapping lips 24 can be multiple, and the multiple first overlapping lips 24 can be spaced apart and arranged on the same side of the first portion 111 along the first direction F1. Figure 1 and Figure 2 As shown in the figure, an example is shown in which the number of the first overlapping lips 24 is two, but it is not limited thereto. The number of the first overlapping lips 24 can be adaptively adjusted according to the size of the clamping gap in the first direction F1.

[0041] Preferably, if Figures 1 to 2As shown, among the multiple first overlapping lips 24 provided on the first part 111, the closer the first overlapping lip 24 is to the connecting part 21, the smaller the size of its protrusion relative to the first part 111. In this way, it is ensured that the farther the part of the first part 111 is from the connecting part 21, the greater its distance from the fixing part 12, effectively increasing the deflection amplitude of the first part 111 under the action of this abutting force and improving the fitting stability between the second part 112 and the door reinforcement plate 43.

[0042] Preferably, as Figure 1 and Figure 2 shown, the above flexible component may further include an abutting protrusion 29, which is provided on the side of the second part 112 facing away from the side door glass 3. The second part 112 contacts the inner door assembly via the abutting protrusion 29. In this way, on the one hand, a flexible buffer is formed between the second part 112 and the door reinforcement plate 43 through the abutting protrusion 29 to reduce wear during the abutting process between the second part 112 and the door reinforcement plate 43; on the other hand, the surface tension generated by the flexible deformation of the flexible abutting protrusion 29 acts on the surface of the door reinforcement plate 43 to improve the fitting strength between the second part 112 and the door reinforcement plate 43.

[0043] Correspondingly, as Figure 2 shown, the above inner door assembly may further include an inner water cut of the inner door trim panel 41, which is provided between the inner door trim panel 41 and the side door glass 3. It should be noted that the above inner door trim panel 41 is an existing technology in this field and will not be elaborated here.

[0044] Preferably, the inner door assembly may further include an inner door insert panel 42, which is fixed to the inner side of the inner door trim panel 41, and one end of the inner door insert panel 42 extends along the first direction F1. The inner door assembly is inserted into the clamping gap through the end of the inner door insert panel 42 extending along the first direction F1.

[0045] Preferably, as Figure 2 shown, the above flexible component may further include a second overlapping lip 25, which is connected to the end of the first part 111 away from the second part 112. The placement part 11 overlaps with one end of the inner door trim panel 41 close to the side door glass 3 through the second overlapping lip 25. In this way, the complete sealing of the gap between the side door glass 3 and the inner door trim panel 41 is effectively achieved through the second overlapping lip 25, the placement part 11 and the first sealing lip 22.

[0046] Preferably, as Figure 2As shown, the second overlapping lip 25 described above can be in a "C" shape, and the opening of the "C" shape faces away from the side door glass 3. Thus, taking the orientation shown in the figure as an example, even if the lower end of the "C" shape (i.e., the end connected to the first part 111) deflects with the first part 111 under the abutting action of the interior door plug 42, the upper end of the "C" shape (i.e., the end overlapping with the interior door trim 41) can always remain overlapped with the interior door trim 41 without detachment due to the special structure of the "C" shape, effectively ensuring the sealing performance of the inner water cut.

[0047] Preferably, as Figure 1 and Figure 2 shown, the above-mentioned flexible component further includes a second sealing lip 23. The second sealing lip 23 and the first sealing lip 22 are arranged at intervals along the first direction F1 on the same side of the placement portion 11. Thus, to further increase the contact points between the side door glass 3 and the inner water cut and improve the sealing performance of the inner water cut.

[0048] It should be noted that it has been mentioned above that "the first sealing lip 22 is arranged at the end of the second part 112 away from the first part 111". In other words, the above-mentioned second sealing lip 23 is arranged at the portion of the placement portion 11 between the second overlapping lip 25 and the first sealing lip 22.

[0049] As Figure 1 and Figure 2 shown, the figure shows an example where the number of the above-mentioned second sealing lips 23 is one. The number of the second sealing lips 23 can be adaptively adjusted according to the length of the placement portion 11 in the first direction F1. For example, the number of the second sealing lips 23 can also be 2, 3, 4 or more.

[0050] As Figure 2 shown, the solid line part in the figure represents the posture of the first sealing lip 22 and the second sealing lip 23 in the natural elongation state, while the dotted line part in the figure represents the posture of the first sealing lip 22 and the second sealing lip 23 when they undergo flexible deformation under the action of the side door glass 3.

[0051] Specifically, as Figure 2As shown, in the natural elongation state, both the first sealing lip 22 and the second sealing lip 23 are sheet-like structures extending along the second direction F2. And when the inner water cut is installed on the inner door assembly, both the first sealing lip 22 and the second sealing lip 23 in the natural elongation state exceed the side door glass 3 in the second direction F2. Thus, when the side door glass 3 rises along the first direction F1, both the first sealing lip 22 and the second sealing lip 23 can be pushed by the side door glass 3 to deflect upward, so that the lower surfaces of both the first sealing lip 22 and the second sealing lip 23 in the natural elongation state are in contact with the inner side wall of the side door glass 3, so as to achieve that both the first sealing lip 22 and the second sealing lip 23 can play a sealing role on the side of the side door glass 3 whether the side door glass 3 rises or falls.

[0052] Preferably, as Figure 1 and Figure 2 shown, the above-mentioned placement part 11 may further include a first placement protrusion 113 and a second placement protrusion 114 both extending along the second direction F2. The first sealing lip 22 is fixed to the first placement protrusion 113, and the second sealing lip 23 is fixed to the second placement protrusion 114. Thus, by providing the first placement protrusion 113 and the second placement protrusion 114, the influence of the deformation of both the first sealing lip 22 and the second sealing lip 23 under the action of the side door glass 3 on the placement part 11 is further reduced, and the stability of the placement part 11 is further improved.

[0053] Preferably, as Figure 1 and Figure 2 shown, the above-mentioned first sealing lip 22 may further include a first flocking layer 221. The first flocking layer 221 is attached to the lower surface of the first sealing lip 22 and the first flocking layer 221 extends from the end of the first sealing lip 22 away from the placement part 11 to the upper surface of the first sealing lip 22. Thus, when the side door glass 3 rises and falls, the first sealing lip 22 can contact the side door glass through the first flocking layer 221, which can not only reduce the frictional noise between the side door glass 3 and the first sealing lip 22, but also the first flocking layer 221 has good water absorption and dirt removal properties, and can scrape off dust, liquid and other sundries on the glass surface during the rising and falling of the side door glass, avoiding the sundries from being brought into the door interior through the side door glass 3.

[0054] Similarly, as Figure 1 and Figure 2 shown, the above-mentioned second sealing lip 23 may further include a second flocking layer 231. The second flocking layer 231 is attached to the lower surface of the second sealing lip 23 and the second flocking layer 231 extends from the end of the second sealing lip 23 away from the placement part 11 to the upper surface of the second sealing lip 23. The arrangement manner and beneficial effects of the second flocking layer 231 are similar to those of the above-mentioned first flocking layer 221, and will not be elaborated here.

[0055] Preferably, as Figure 1 and Figure 2 shown, the above-mentioned placement part 11 may further include a support rib 115. The support rib 115, the first placement protrusion 113, and the second placement protrusion 114 are all provided on the same side of the placement part 11. The support rib 115 is arranged between the first placement protrusion 113 and the second placement protrusion 114 to improve the support strength and bending strength of the part of the placement part 11 between the first placement protrusion 113 and the second placement protrusion 114, and further improve the stability of the placement part 11 and the abutting tightness with the door reinforcement plate 43.

[0056] Preferably, as Figure 1 and Figure 2 shown, the above-mentioned flexible component may further include a first covering part 27. The first covering part 27 covers one end of the support rib 115 facing the side door glass 3. In this way, it effectively avoids the friction damage between the first sealing lip 22 and the support rib 115 during the lifting and lowering of the side door glass 3.

[0057] Optionally, the above-mentioned flexible component may be made of TPV (Thermoplastic Vulcanizate). Optionally, the above-mentioned rigid component may be made of PP (Polypropylene thermoplastic resin). In this way, by using the high elasticity and low-temperature toughness of TPV, the deformation sensitivity of the connecting part 21 and the dynamic sealing performance between the sealing lip and the side door glass 3 can be effectively improved; while using the rigidity and low shrinkage rate characteristics of PP, the installation stability and assembly accuracy of the inner water cut are effectively ensured, and the generation of looseness and abnormal noise is effectively avoided.

[0058] Preferably, the above-mentioned inner water cut may be an integrally extruded molding. On the one hand, the melting temperature windows of TPV and PP match. Through the co-extrusion die head design, an interfacial bonding strength of ≥10 MPa can be formed, and the tearing strength of the bonding surface > 5 kN / m, ensuring no delamination risk during frequent glass lifting and effectively guaranteeing the connection stability of the flexible component and the rigid component; on the other hand, the one-piece molding avoids the assembly errors in the traditional assembly process and significantly improves the product competitiveness and industrial value.

[0059] Referring to Figure 2 , the embodiment of the second aspect of the present application further provides a vehicle door, including the above-mentioned side door glass 3, the above-mentioned inner door assembly, and the inner water cut according to any one of the above-mentioned embodiments. Therefore, it has all the beneficial technical effects of this inner water cut and will not be elaborated here.

[0060] Preferably, as Figure 2 shown, the above-mentioned inner door assembly may include the above-mentioned interior door trim panel 41, the interior door plug panel 42, and the door reinforcement plate 43, and its structure has been described above and will not be elaborated here.

[0061] Preferably, the above door can also include an outer door assembly and an outer water deflector, both of which are prior arts in the field and will not be elaborated herein.

[0062] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
