For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination manners of the various specific technical features in the present utility model will not be described separately.

It should be understood that the orientation descriptions "above", "below", "outside", and "inside" involved are all orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which can be the left and right directions in the normal use state or not.

[0028] It should be noted that the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including such element. The term "connection" includes both direct connection and indirect connection unless otherwise specified.

[0029] In the following specific embodiments, the water cut sealing assembly can be applied to the door with a lift window of any type of vehicle. Exemplarily, the water cut sealing assembly can be applied to the door of a truck cab. Exemplarily, the water cut sealing assembly can also be applied to the door of a passenger compartment of a sedan. For the sake of convenience of description, the water cut sealing assembly is taken as an example applied to the door of a sedan for illustration below.

[0030] In some embodiments, as Figure 1 shown, the water cut sealing assembly 10 includes: a water cut body 100 and a buckle member 200. The water cut body 100 is used to seal the window glass 30 and the door structure 20 ( Figure 1 In which the door structure 20 and the window glass 30 are both represented by dashed lines, Figure 1 What is shown is the state after the water cut sealing assembly 10 is assembled, and it does not mean that the door structure 20 and the window glass 30 are part of the water cut sealing assembly 10). Among them, the door structure 20 can be the inner sheet metal of the door or the outer door panel of the door. The window glass 30 can move up and down relative to the door structure 20. In order to prevent the window glass 30 from rubbing or colliding with the door structure 20 configured as a metal structure during the up and down movement, resulting in the window glass 30 being broken or scratched, it is necessary to have a certain distance between the window glass 30 and the door structure 20, so as to form a certain gap between the window glass 30 and the door structure 20. However, the liquid outside the vehicle enters through this gap, such as into the door, which may cause the metal structure inside the door to rust. Therefore, it is necessary to set the water cut sealing assembly 10 to seal this gap. Specifically, the water cut sealing assembly 10 is set as a part with a flexible structure, and through this flexible structure, it abuts against the window glass 30 and the door structure 20, so as to be able to reduce the possibility of scratching the window glass 30 while realizing the sealing of the gap between the window glass 30 and the door structure 20.

[0031] The buckle member 200 is fixed to the water cut body 100. The buckle member 200 has a hook 210. The hook 210 is used to engage the water cut body 100 with the door structure 20. By engaging the water cut body 100 with the door structure 20 through the buckle member 200, the detachable assembly of the water cut body 100 and the door structure 20 can be realized, so that the installation and disassembly of the water cut body 100 can be facilitated.

[0032] Wherein, in the state where the water cut body 100 is engaged with the door structure 20, all parts of the water cut body 100 are located between the door structure 20 and the window glass 30. It can be understood that by engaging the water cut body 100 with the door structure 20 through the buckle member 200, the water cut body 100 can be enabled to bypass the upper edge of the door structure 20, so that all parts of the water cut body 100 do not need to protrude between the door structure 20 and the window glass 30 to form a hidden water cut, thereby reducing the blockage of the occupant's line of sight by the water cut body 100; and when the window glass 30 is lowered to the lowest position, the door structure 20 can still block the water cut body 100, so that the water cut body 100 remains in an invisible state. Since the material of the water cut body 100 is different from that of the door structure 20, the body consistency can be improved by making the water cut body 100 in an invisible state.

[0033] At the same time, on the basis of forming a hidden water cut, the assembly structure of the related hidden water cut is also located between the door structure and the window glass. Both the water cut body and the assembly structure need to occupy the space between the door structure 20 and the window glass 30. And since all parts of the water cut body need to be hidden in this space, this assembly structure will cause the water cut body to be set to a smaller size, resulting in a reduction in the sealing performance of the water cut body for the gap between the door structure 20 and the window glass 30. To solve this technical problem, in this embodiment, the hook structure passes through the door structure 20, that is, the assembly structure of the water cut sealing assembly 10 extends from the side of the door structure 20 facing the window glass 30 to the side of the door structure 20 facing away from the window glass 30, so that this assembly structure can be located outside the door structure. Thus, while engaging the water cut body 100 with the door structure 20, the space occupied by the hook 210 between the door structure 20 and the window glass 30 is reduced, so that the size of the water cut body 100 does not need to be reduced, and the water cut body 100 has a better sealing effect.

[0034] An embodiment of the present utility model provides a water cut component. The water cut component includes a water cut body for sealing the gap between a door structure and a window glass, and a buckle member fixedly connected to the water cut body. The buckle member has a hook that can be engaged with the door structure. Among them, in the state where the water cut body is engaged with the door structure, each part of the water cut body is located between the door structure and the window glass, that is, the water cut body can be hidden between the door structure and the window glass and will not protrude from the upper edge of the door structure, thereby reducing the blocking effect of the water cut structure on the line of sight of the vehicle occupants. At the same time, in the state where the water cut body is engaged with the door structure, the hook passes through the door structure, that is, the assembly structure of the water cut sealing component can extend from the space between the door structure and the window glass to outside this space, thereby reducing the occupation of this space by the assembly structure, enabling a larger-sized water cut body to be arranged in this space, and further improving the sealing performance of the water cut body.

[0035] In some embodiments, as Figure 2 shown, the water cut body 100 has a mounting hole 110 for the hook 210 to pass through. The buckle member 200 is detachably connected to the water cut body 100 through the mounting hole 110. Specifically, the buckle member 200 is detachably connected to the water cut body 100 by passing the hook 210 through the mounting hole 110. By detachably connecting the buckle member 200 to the water cut body 100, the water cut body 100 can be replaced separately and the buckle member 200 can be reused when the water cut body 100 is damaged.

[0036] At the same time, the buckle member 200 further includes a limit protrusion 220. In the state where the buckle member 200 is assembled with the water cut body 100, the hook 210 and the limit protrusion 220 are located on both sides of the water cut body 100, and the outer edge dimension of the limit protrusion 220 is larger than the outer edge dimension of the mounting hole 110, that is, the hook 210 and the limit protrusion 220 are respectively arranged at two opposite ends of the buckle member 200. After the hook 210 passes through the mounting hole 110, the limit protrusion 220 cannot pass through the mounting hole 110 and thus abuts against the water cut body 100 to limit the relative movement between the buckle member 200 and the water cut body 100, thereby reducing the possibility of the buckle member 200 coming out of the mounting hole 110 and improving the assembly reliability of the buckle member 200 and the water cut body 100.

[0037] In some embodiments, as Figure 3 shown, the water cut body 100 has a limit groove 121, and the mounting hole 110 is located at the bottom wall of the limit groove 121, so that after the buckle member 200 is assembled with the water cut body 100, the limit protrusion 220 can be located in the limit groove 121; the dimension of the limit groove 121 in the first direction is larger than the dimension in the second direction ( Figure 3The first direction is represented by arrow I, and the second direction is represented by arrow II. The first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the depth direction of the limiting groove 121. It can be understood that in a cross-section perpendicular to the depth direction of the limiting groove 121, the figure formed by the outer edge of the limiting groove 121 has different dimensions in two perpendicular directions. This figure can be, for example, a rectangle, or it can also be, for example, an ellipse. It should be noted that the limiting groove 121 can be formed in different ways. Exemplarily, the limiting groove 121 can be formed by the inner concavity of the outer surface of the water cut body for abutting against the limiting protrusion 220. Exemplarily, the limiting groove 121 can also be formed by being surrounded by the limiting ribs 122 protruding from the outer surface. Specifically, both limiting ribs 122 extend along the first direction, and in the second direction, the two limiting ribs 122 are spaced apart and are respectively located on both sides of the mounting hole 110, thereby surrounding and forming the limiting groove 121.

[0038] Meanwhile, in the state where the buckle member 200 is assembled with the water cut body 100, the limiting protrusion 220 is located in the limiting groove 121, and the dimension of the limiting protrusion 220 in the first direction is greater than the dimension of the limiting groove 121 in the second direction. It can be understood that the limiting protrusion 220 can be located in the limiting groove 121, so that in the first direction, the dimension of the limiting protrusion 220 is smaller than the dimension of the limiting groove 121, and in the second direction, the dimension of the limiting protrusion 220 is also smaller than the dimension of the limiting groove 121. Moreover, since the dimension of the limiting protrusion 220 in the first direction is greater than the dimension of the limiting groove 121 in the second direction, the rotation of the limiting protrusion 220 can be restricted by the inner wall of the limiting groove 121, and further the rotational movement of the buckle member 200 can be restricted. Specifically, in the length direction of the buckle member 200, the hook 210 and the limiting protrusion 220 are located at both ends of the buckle member 200. After the hook 210 passes through the mounting hole 110, the buckle member 200 can still rotate relative to the water cut body 100 around the axis in its own length direction. The rotation of the buckle member 200 may cause Figure 2 the hook 210 in [reference] to bear an additional torque, and may also cause additional wear to the mounting hole 110, thereby reducing the mounting reliability of the buckle member 200 and the water cut body 100. By providing a limiting groove with different dimensions in two directions and making the dimension of the limiting groove 121 in the second direction smaller than the dimension of the limiting protrusion 220 in the first direction, during the rotation of the buckle member 200, the movement of the limiting protrusion 220 will be restricted by the inner wall of the limiting groove 121, thereby restricting the rotation of the buckle member 200 and further improving the assembly reliability of the buckle member 200 and the water cut body 100.

[0039] In some embodiments, such as Figure 3As shown, the first direction is the length direction of the water deflector body 100, that is, this length direction is the direction in which the water deflector body 100 has the largest dimension. When the water deflector body 100 is assembled between the door structure 20 and the window glass 30, this length direction is the same as the length direction of the vehicle. By setting the first direction as the length direction of the water deflector body 100, the limiting groove 121 can be fully utilized in the length direction of the water deflector body 100, so that the difference between the dimension of the limiting groove 121 in the first direction and the dimension of the limiting groove 121 in the second direction is larger, thereby making the rotation of the limiting projection 220 by the limiting groove 121 more reliably restricted. Optionally, the dimension of the limiting groove 121 in the first direction is the same as the dimension of the water deflector body 100 in the length direction, so that the limiting groove 121 can form an integral limiting groove 121 along the length direction of the water deflector body 100, thereby enabling the integral molding of the limiting groove 121 and reducing the manufacturing difficulty of the water deflector body 100.

[0040] In some embodiments, in combination with Figure 1 and Figure 4 , the water deflector body 100 includes a body portion 120 and a sealing portion 130. The body portion 120 is fixedly connected to the buckle member 200. The sealing portion 130 extends from the surface of the body portion 120 and is used for abutting against the window glass 30 and the door structure 20, so as to realize the sealing of the gap between the window glass 30 and the door structure 20. Among them, the stiffness of the body portion 120 is configured to be greater than the stiffness of the sealing portion 130. It can be understood that the body portion 120 is used for connecting with the buckle member 200 and needs to be connected to the door structure 20 through the buckle member 200. The body portion 120 is the part of the water deflector body 100 that needs to be responsible for bearing the connection load, and the stiffness of the body portion 120 needs to be set larger, so that the assembly of the water deflector body 100 and the door structure 20 is more reliable. At the same time, the sealing portion 130 needs to abut against the door structure 20 and the window glass 30, and needs to realize the sealing of the gap between the door structure 20 and the window glass 30. By setting the sealing portion 130 as a flexible structure with a smaller stiffness, the risk of the window glass 30 being scratched can be reduced, and the abutting force between the sealing portion 130 and the window glass 30 and the door structure 20 can be further increased through the elastic deformation of the sealing portion 130, thereby further improving the sealing reliability of the sealing portion 130 for the gap between the window glass 30 and the door structure 20.

[0041] Optionally, the end of the sealing portion 130 extending from the body portion 120 forms a free end, and this free end is used for abutting against the door structure 20 and the window glass 30, so that the sealing portion 130 is more likely to generate elastic deformation, and further improves the sealing ability of the sealing portion 130 for the gap between the window glass 30 and the door structure 20.

[0042] In some embodiments, in combination withFigure 1 and Figure 4 , the sealing part 130 includes: a first lip 131 and a second lip 132. The first lip 131 is used to abut against the window glass 30, and the second lip 132 is used to abut against the door structure 20. Moreover, the first lip 131 can abut against the second lip 132. It can be understood that, in the state where the water cut sealing assembly 10 is installed between the door structure 20 and the window glass 30, the first lip 131 and the second lip 132 abut against each other to form a sealing surface. The gap between the water cut body 100 and the window glass 30 is sealed by the first lip 131, making it difficult for external liquid flow to enter the door structure through the gap between the water cut body 100 and the window glass 30. The gap between the water cut body 100 and the door structure 20 is sealed by the second lip 132, making it difficult for external liquid flow to enter the door structure through the gap between the water cut body 100 and the door structure 20. Through the abutment of the first lip 131 and the second lip 132, it is difficult for external liquid flow to enter the interior of the water cut body 100 through the gap between the first lip 131 and the second lip 132, thus achieving the sealing of the gap between the door structure 20 and the window glass 30. Moreover, through the abutment of the first lip 131 and the second lip 132, the buckle 200 can also be blocked by the first lip 131, making it invisible to external personnel. It should be noted that, in the state where the water cut sealing assembly 10 has not been installed between the door structure 20 and the window glass 30, the structures of the first lip 131 and the second lip 132 are any structures that can make the first lip 131 and the second lip 132 abut against each other. Exemplarily, as Figure 5 shown, in the state where the water cut sealing assembly 10 has not been installed between the door structure 20 and the window glass 30, the first lip 131 and the second lip 132 still remain in abutment, making the shielding of the buckle 200 by the first lip 131 and the second lip 132 more reliable; Exemplarily, as Figure 6 shown, in the state where the water cut sealing assembly 10 has not been installed between the door structure 20 and the window glass 30, there is a certain distance between the first lip 131 and the second lip 132. By making the first lip 131 and the second lip 132 undergo a certain elastic deformation, the first lip 131 and the second lip 132 can be made to abut against each other. Thus, in the state where the water cut sealing assembly 10 is installed between the door structure 20 and the window glass 30, the first lip 131 and the second lip 132 abut against each other, and further, the first lip 131 can block the buckle 200, making the buckle 200 in an invisible state.

[0043] Meanwhile, as Figure 5As shown, in the vertical direction, the first lip 131 is located above the limit protrusion 220, and the first lip 131 shields the limit protrusion 220. It can be understood that regardless of whether the water cut sealing assembly is installed between the door structure and the window glass, the first lip 131 can shield the limit protrusion 220, so that the limit protrusion 220 is in a non-visible state. Specifically, the limit protrusion 220 is in surface contact with the body part 120, and the projection of the first lip 131 on this surface can cover the limit protrusion 220.

[0044] Among them, each lip protrudes from the body part 120 and forms a free end. By contacting other structures with the free end, greater elastic deformation can be generated in each lip, so that the sealing effect of each lip on the gap between the door structure 20 and the window glass 30 is better. Optionally, in combination Figure 1 and Figure 5 , the first lip 131 includes a first part 1311 and a second part 1312. The end of the first part 1311 is fixed to the end of the second part 1312. The first part 1311 is used to contact the window glass 30, and the second part 1312 is used to contact the second lip 132. And the extending direction of the first part 1311 forms a certain acute angle with the extending direction of the second part 1312. It can be understood that the first lip 131 is bent by the first part 1311 and the second part 1312 to form a structure similar to a U shape. One end of this U-shaped structure is fixed to the body part 120. The connecting part of the first part 1311 and the second part 1312 forms a first free end, and the opposite end of the second part 1312 for connecting with the first part 1311 forms a second free end. The first free end is used to contact the window glass 30, and the second free end is used to contact the second lip 132. That is, by bending the first lip to form two free ends that can generate greater elastic deformation, and sealing the gap between the first lip 131 and the window glass 30 and the gap between the first lip 131 and the second lip 132 through the two free ends, the sealing effect of these two gaps is improved, and the buckle 200 is more reliably shielded. Optionally, the part of the first lip 131 for contacting the window glass 30 has a wear-resistant layer, so as to reduce the wear between the first lip 131 and the window glass 30 and extend the service life of the first lip 131. At the same time, as Figure 5 shown, in the vertical direction, the second part 1312 is located above the limit protrusion 220, and the second part 1312 shields the limit protrusion 220. It can be understood that regardless of whether the water cut sealing assembly is installed between the door structure and the window glass, the second part 1312 can shield the limit protrusion 220, so that the limit protrusion 220 is in a non-visible state. Specifically, the limit protrusion 220 is in surface contact with the body part 120, and the projection of the second part 1312 on this surface can cover the limit protrusion 220.

[0045] In some embodiments, in combination with Figure 1 and Figure 4 , the sealing portion 130 further includes a third lip 133. In the vertical direction, the third lip 133 is located below the first lip 131. The third lip 133 is located between the window glass 30 and the door structure 20 and can contact the window glass 30. It can be understood that during the lifting and lowering of the window glass 30, the bottom of the window glass 30 may collide with the door structure 20. By separating the bottom of the window glass 30 from the door structure 20 through the third lip 133, the possibility of collision between the window glass 30 and the door structure 20 during the lifting and lowering of the window glass 30 can be reduced.

[0046] In some embodiments, in combination with Figure 1 and Figure 4 , the water deflector body 100 further includes a support portion 140. The support portion 140 is located on the clamping surface of the body portion 120 and at the edge of the clamping surface. The hook 210 extends from the clamping surface. In a state where the water deflector body 100 is clamped to the door structure 20 by the hook 210, the clamping surface abuts against the door structure 20, and the door structure 20 is clamped by the hook 210 and the clamping surface, thereby fixing the water deflector body 100 to the door structure 20. Moreover, by providing the support portion 140 at the edge of the clamping surface, the contact area with the door structure 20 is increased, so that the connection between the water deflector body 100 and the door structure 20 is more reliable. Optionally, the stiffness of the support portion 140 is less than the stiffness of the body portion 120. Thus, when the clamping surface deflects relative to the door structure 20, the support portion 140 can undergo elastic deformation and apply a greater abutting force to the door structure 20 through the elastic deformation, thereby further increasing the assembly reliability between the water deflector body 100 and the door structure 20.

[0047] The present utility model further provides a door assembly. The door assembly can be the door of various vehicles having a lifting glass. Exemplarily, the door assembly is the side door of a sedan. Exemplarily, the door assembly can be the cab door of a truck. For the convenience of description, the structure of the door assembly will be described below by taking the door assembly as the side door of a sedan as an example.

[0048] In some embodiments, as Figure 6 shown, the door assembly 1 includes a door structure 20, a window glass 30, and as shown in the accompanying drawings of the specification Figures 1 to 4The water cut sealing assembly 10 shown in any one of the figures. The window glass 30 is connected to the door structure 20, and the window glass 30 can move up and down relative to the door structure. The door structure 20 is the framework part of the door, including an inner sheet metal, an outer door panel, an inner door panel, and a door panel structure reinforcing member. At least part of the window glass 30 is located in the space between the outer door panel and the inner door panel and can move up and down in this space. Among them, there is a lifting structure in this space, and the window glass 30 is carried on this lifting structure, and this lifting structure can move up and down to drive the window glass 30 to move up and down. There is also a guiding structure in the door structure 20 and this space, and this guiding structure can make the window glass 30 move up and down along a predetermined trajectory. The water cut sealing assembly 10 is located between the door structure 20 and the window glass 30 and is used to seal the gap between the door structure 20 and the window glass 30, thereby reducing the possibility of external liquid flowing into the door structure 20 through this gap and causing the door structure 20 to rust.

[0049] Among them, the door structure 20 is bent away from the window glass 30 to form a receiving portion 21. The receiving portion 21 and the window glass 30 enclose a receiving space 22. The water cut body 100 is located in the receiving space 22. It can be understood that the bending of the door structure 20 provides a receiving space for the water cut body 100, so that all parts of the water cut body 100 can be received between the door structure 20 and the window glass 30. Moreover, the receiving portion 21 can block the water cut body 100 to form a hidden water cut, so that the water cut body 100 will not block the line of sight of the vehicle occupants. Moreover, in the state where the window glass 30 is lowered to the lowest position, the water cut body 100 can still be blocked by the receiving portion 21, so that the water cut body 100 is in a non-visible state, improving the visual consistency of the door.

[0050] Moreover, the receiving portion 21 has a clamping hole 23. The hook 210 can be engaged with the clamping hole 23 to clamp the water cut sealing assembly 10 to the door structure 20. Specifically, the hook 210 can pass through the mounting hole 110 and the clamping hole 23, so that the limiting protrusion presses against the water cut body 100, thereby clamping the water cut body 100 and the receiving portion 21 between the hook 210 and the limiting protrusion 220, thereby realizing the fixed connection between the water cut body 100 and the door structure 20.

[0051] In some embodiments, as Figure 7 shown, the clamping hole 23 includes: a first clamping hole 231 and a second clamping hole 232. The first clamping hole 231 is an elongated hole, and the dimension of this elongated hole in the third direction is greater than the dimension in the fourth direction (the third direction and the fourth direction are in Figure 7(respectively indicated by arrow III and arrow IV). At the same time, the second engaging hole 232 is a circular hole and is located on one side of the first engaging hole 231 in the third direction. It can be understood that there are multiple engaging hooks 210, and each of the multiple engaging hooks 210 is respectively engaged in the first engaging hole 231 and the second engaging hole 232, which can realize the engagement between the water cut body 100 and the door structure 20. If all the engaging holes are circular holes, it will cause the engaging hook 210 to easily form an assembly interference with each engaging hole. The first engaging hole 231 is set as an elongated hole, and the first engaging hole 231 is used to limit the water cut body 100 in the fourth direction and the depth direction of the first engaging hole 231. The engaging hook 210 can move relative to the first engaging hole 231 in the fourth direction, so as to adjust the position of the water cut body 100, so that another engaging hook 210 can be aligned with the second engaging hole 232, so that the engaging hook 210 can be inserted into the second engaging hole 232. The second engaging hole 232 is a circular hole, which can limit the engaging hook 210 in the depth direction, the third direction and the fourth direction of the second engaging hole 232, so as to limit the movement of the water cut body 100 in each direction, so that the water cut body 100 can be limited and the assembly difficulty of the water cut body 100 can be reduced.

[0052] Optionally, as Figure 7 shown, there are multiple first engaging holes 231, and each of the first engaging holes 231 is arranged at intervals in the third direction. The second engaging hole 232 is located outside each of the first engaging holes 231 in the third direction, that is, the second engaging hole 232 is not located between two first engaging holes 231.

[0053] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
