[0002] The side window assemblies of construction machinery or buses have holes drilled in the glass, through which water drains outside the vehicle. Decorative covers are usually installed over these holes for dust protection. However, construction machinery and buses require cab sealing tests, which involve releasing smoke into the cab to check for leaks and determine the sealing performance. Since the area under the drainage cover is where water needs to be drained, smoke leaks are inevitable, affecting the smoke leakage sealing test. Utility Model Content

[0025] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0026] In view of this, in order to solve the above problems, please refer to the following: Figures 1-6This embodiment provides a drainage decorative cover 1, which includes a cover body 10 and a separating membrane 20. The cover body 10 has a receiving cavity 11 and a drain hole 12 connecting the receiving cavity 11 to the outside. The receiving cavity 11 is used to receive fluid. The separating membrane 20 is disposed in the receiving cavity 11 and is used to divide the receiving cavity 11 into a first space 111 and a second space 112. The drain hole 12 communicates with the second space 112.

[0027] The fluid includes gas and liquid. When the gas is placed in the first space 111, the first space 111 is isolated from the second space 112. When the liquid is placed in the first space 111, the liquid causes the isolation membrane 20 to deform, so that the first space 111 and the second space 112 are connected, and the liquid is discharged from the drain hole 12.

[0028] The cover 10 has a receiving cavity 11, which can contain fluid, including gas and liquid. For example, the receiving cavity 11 can store flue gas; or, for example, it can store water. The cover 10 also has a drain hole 12, which connects the receiving cavity 11 to the outside, allowing liquid in the receiving cavity 11 to drain to the outside. Optionally, the material of the cover 10 is selected from at least one of plastic, metal, and rubber.

[0029] The cover 10 is installed onto the component 50 to be installed. The component 50 is provided with a liquid guiding channel 51, which connects to the receiving cavity 11. Optionally, the component 50 can be a glass substrate, a light-transmitting plate, a housing, etc. Optionally, the liquid guiding channel 51 can be a liquid guiding hole or a liquid guiding groove, etc. For example, the liquid guiding channel 51 can directly connect to the receiving cavity 11, or the liquid guiding channel 51 can indirectly connect to the receiving cavity 11 through other components. Specifically, liquid located in the liquid guiding channel 51 can flow to the receiving cavity 11. Gas located in the liquid guiding channel 51 can also flow to the receiving cavity 11.

[0030] The separating membrane 20 is used to divide the accommodating cavity 11 into a first space 111 and a second space 112. The material of the separating membrane 20 is selected from at least one of silicone and plastic. When the pressure on the separating membrane 20 is greater than a preset pressure, the separating membrane 20 can deform to connect the first space 111 and the second space 112. When the pressure on the separating membrane 20 is less than the preset pressure, the separating membrane 20 returns to its original shape, isolating the first space 111 from the second space 112; or, when the pressure on the separating membrane 20 is less than the preset pressure, the separating membrane 20 does not deform, and the first space 111 and the second space 112 remain isolated.

[0031] Therefore, the drainage decorative cover 1 provided in this embodiment, by setting an isolation membrane 20 in the drainage decorative cover 1, divides the accommodating cavity 11 into a first space 111 and a second space 112. When the isolation membrane 20 encounters water, the water presses down on the isolation membrane 20 under the action of gravity, causing the isolation membrane 20 to deform, so that the first space 111 connects to the second space 112, thereby realizing drainage. When the isolation membrane 20 encounters smoke, the smoke cannot press the isolation membrane 20, so the first space 111 cannot connect to the second space 112, so that the smoke cannot leak out from the drainage decorative cover 1, avoiding affecting the smoke leakage sealing test. Therefore, the drainage decorative cover 1 provided in this application can both drain water and prevent smoke leakage.

[0032] Please refer to this as well. Figures 1-6 In one embodiment, the cover 10 is provided with an auxiliary protrusion 30 placed in the second space 112, the drain hole 12 is provided on the periphery of the auxiliary protrusion 30, the middle part of the isolation membrane 20 is provided on the auxiliary protrusion 30, the edge part of the isolation membrane 20 is provided outside the auxiliary protrusion 30, and there is a gap between the edge part of the isolation membrane 20 and the drain hole 12.

[0033] An auxiliary boss 30 protrudes from the inner wall forming the accommodating cavity 11. A drain hole 12 is located on the periphery of the auxiliary boss 30, and its position is lower than the top surface of the auxiliary boss 30. The middle portion of the isolation membrane 20 is positioned on the top surface of the auxiliary boss 30, and the edge portion of the isolation membrane 20 is spaced apart from the drain hole 12. In other words, there is a gap between the edge portion of the isolation membrane 20 and the drain hole 12 to provide space for the isolation membrane 20 to deform.

[0034] Optionally, the auxiliary boss 30 and the isolation membrane 20 are detachably connected. Optionally, the connection method between the auxiliary boss 30 and the isolation membrane 20 includes, but is not limited to, snap-fit, adhesive connection, threaded connection, etc., and this embodiment does not limit this.

[0035] Optionally, there may be multiple drainage holes 12, which are arranged around the auxiliary boss 30 in the circumferential direction. Optionally, the spacing between two adjacent drainage holes 12 may be the same. Optionally, the spacing between at least some of the two adjacent drainage holes 12 may be different.

[0036] Specifically, when the pressure on the edge portion of the isolation membrane 20 is greater than a preset pressure, the edge portion of the isolation membrane 20 bends downward to connect the first space 111 and the second space 112. When the pressure on the edge portion of the isolation membrane 20 is less than the preset pressure, the edge portion of the isolation membrane 20 returns to its original shape, isolating the first space 111 from the second space 112; or, when the pressure on the edge portion of the isolation membrane 20 is less than the preset pressure, the edge portion of the isolation membrane 20 does not deform, and the first space 111 and the second space 112 remain isolated.

[0037] Therefore, this embodiment improves the reliability of the drainage decorative cover 1 by providing an auxiliary boss 30 and defining the positional relationship between the isolation membrane 20, the auxiliary boss 30, and the drain hole 12, thereby providing space for the isolation membrane 20 to deform.

[0038] Furthermore, the auxiliary boss 30 has a guide arc surface 31, which protrudes along the arrangement direction from the drain hole 12 to the isolation membrane 20, and the middle part of the isolation membrane 20 is disposed on the guide arc surface 31.

[0039] The auxiliary boss 30 has a conductor arc surface, or in other words, the guide boss is arched in shape, and the middle part of the isolation membrane 20 is placed on the guide arc surface 31.

[0040] Therefore, by providing the guide arc surface 31, this embodiment provides a larger space for the isolation membrane 20 to deform, making it easier for the liquid to press the isolation membrane 20 to deform. On the other hand, when the liquid is placed in the middle part of the isolation membrane 20, under the action of gravity, the guide arc surface 31 guides the liquid to flow naturally from the middle part of the isolation membrane 20 to the edge part of the isolation membrane 20, providing a good foundation for the liquid to drain from the drainage decorative cover 1, thereby further improving the reliability of the drainage decorative cover 1.

[0041] Furthermore, the drain hole 12 includes a first drain sub-hole 121 and a second drain sub-hole 122. The first drain sub-hole 121 is located on one side of the auxiliary boss 30, and the second drain sub-hole 122 is located on the other side of the auxiliary boss 30.

[0042] The number of the first row of liquid sub-holes 121 is one or more, and the number of the second row of liquid sub-holes 122 is one or more. Optionally, the number of the first row of liquid sub-holes 121 is equal to the number of the second row of liquid sub-holes 122.

[0043] For example, the first row of liquid sub-holes 121 is located on the left side of the auxiliary boss 30, and the second row of liquid sub-holes 122 is located on the right side of the auxiliary boss 30. Optionally, the first row of liquid sub-holes 121 and the second row of liquid sub-holes 122 are symmetrically arranged along the central axis of the auxiliary boss 30. Optionally, the first row of liquid sub-holes 121 is located below one side edge of the isolation membrane 20, and the second row of liquid sub-holes 122 is located below one side edge of the isolation membrane 20.

[0044] Therefore, by providing the first drain hole 121 and the second drain hole 122 on opposite sides of the auxiliary boss 30, this embodiment facilitates the rapid discharge of liquid from the second space 112 through the first drain hole 121 and the second drain hole 122 into the drainage decorative cover 1, thereby improving the drainage performance of the drainage decorative cover 1.

[0045] And / or, the cover 10 is provided with an abutment block 16 placed on the inner wall of the first space 111, and the side of the abutment block 16 facing the drain hole 12 is used to abut the isolation membrane 20.

[0046] The abutment block 16 is disposed around the inner wall of the receiving cavity 11, and the circumferential direction of the abutment block 16 is the same as the circumferential direction of the auxiliary boss 30. The abutment block 16 can cooperate with the isolation membrane 20 to isolate the first space 111 from the second space 112.

[0047] Therefore, by providing the abutting block 16 in this embodiment, which can abut the isolation membrane 20, it can not only prevent the isolation membrane 20 from tilting upward, but also improve the sealing performance of the first space 111 and the second space 112 when they are isolated, thereby improving the reliability of the drainage decorative cover 1.

[0048] Furthermore, the auxiliary boss 30 is provided with a mounting hole 32, and the isolation membrane 20 is provided with a mounting post 21, which is inserted into the mounting hole 32.

[0049] The auxiliary boss 30 has a mounting hole 32 on its surface facing the isolation membrane 20, and a mounting post 21 is provided on the side of the isolation membrane 20 facing the auxiliary boss 30. The mounting post 21 is inserted into the mounting hole 32 to fix the isolation membrane 20 to the auxiliary boss 30.

[0050] Therefore, by providing mounting holes 32 and mounting posts 21, the isolation membrane 20 is detachably connected to the auxiliary boss 30, which not only improves the connection performance between the isolation membrane 20 and the auxiliary boss 30, but also facilitates the replacement and maintenance of the isolation membrane 20, thereby reducing the maintenance cost of the drainage decorative cover 1.

[0051] Please refer to this as well. Figures 1-6In another embodiment, the cover 10 includes a first sub-cover 13 and a second sub-cover 14. The first sub-cover 13 is provided with a liquid guide tube 131 that communicates with the first space 111. The liquid guide tube 131 is used to communicate with the liquid guide channel 51 of the component to be installed 50. The second sub-cover 14 is connected to the first sub-cover 13. The second sub-cover 14 and the first sub-cover 13 form the receiving cavity 11. The second sub-cover 14 is provided with the drain hole 12.

[0052] The cover 10 is formed by combining a first sub-cover 13 and a second sub-cover 14. The first sub-cover 13 and the second sub-cover 14 are detachably connected. Optionally, the connection method between the first sub-cover 13 and the second sub-cover 14 includes, but is not limited to, snap-fit, adhesive connection, threaded connection, etc., and this embodiment does not limit this.

[0053] The first sub-cover 13 is provided with a liquid guide tube 131, and the liquid guide channel 51 is connected to the receiving cavity 11 through the liquid guide tube 131. The liquid guide tube 131 protrudes from the first sub-cover 13. Optionally, the liquid guide channel 51 is a liquid guide hole, and the liquid guide tube 131 is inserted into the liquid guide hole.

[0054] A portion of the second sub-cover 14 and a portion of the first sub-cover 13 enclose a cavity 11. Optionally, the first sub-cover 13 has a first space 111, and the second sub-cover 14 has a second space 112. The second sub-cover 14 is provided with a drain hole 12, which penetrates the side wall of the second sub-cover 14 to communicate with the outside. The drain hole 12 also penetrates the inner wall of the cavity 11 formed by the second sub-cover 14 to communicate with the second space 112.

[0055] Optionally, the isolation membrane 20 is disposed inside the first sub-cover 13; or, the isolation membrane 20 is disposed inside the second sub-cover 14; or, the isolation membrane 20 is disposed at the connection between the first sub-cover 13 and the second sub-cover 14.

[0056] Therefore, by providing a first sub-cover 13 and a second sub-cover 14, this embodiment facilitates the installation of the isolation membrane 20 into the receiving cavity 11, reducing the difficulty of installation; it also facilitates the replacement and maintenance of the isolation membrane 20, reducing the maintenance cost of the drainage decorative cover 1.

[0057] Furthermore, the liquid guide tube 131 includes a first semi-ring portion 1311 and a second semi-ring portion 1312 spaced apart, both of which are used to connect to the liquid guide channel 51 of the component to be installed 50.

[0058] The first semi-ring portion 1311 and the second semi-ring portion 1312 are semi-ring-shaped, with a gap between them. Optionally, both the first semi-ring portion 1311 and the second semi-ring portion 1312 can be inserted into the liquid guiding channel 51; or, the first semi-ring portion 1311 and the second semi-ring portion 1312 can be sleeved on the liquid guiding channel 51; or, the first semi-ring portion 1311 and the second semi-ring portion 1312 can be connected to the liquid guiding channel 51 of the component to be installed 50 by other fasteners.

[0059] For example, when the liquid guiding channel 51 is a circular liquid guiding hole, the first semi-ring portion 1311 and the second semi-ring portion 1312 are inserted into the liquid guiding hole.

[0060] Therefore, by providing a first semi-ring portion 1311 and a second semi-ring portion 1312 that are spaced apart from each other, this embodiment provides an installation adjustment margin for the liquid guide tube 131 when it is connected to the liquid guide channel 51 of the part to be installed 50, thereby reducing the difficulty of connecting the liquid guide tube 131 to the liquid guide channel 51 and improving the adaptability of the drainage decorative cover 1.

[0061] Furthermore, one of the first sub-cover 13 and the second sub-cover 14 is provided with a limiting groove 151, and the other of the first sub-cover 13 and the second sub-cover 14 is provided with a limiting block 152, the limiting block 152 being disposed within the limiting groove 151.

[0062] For example, the first sub-cover 13 is provided with a limiting groove 151, and the second sub-cover 14 is provided with a limiting block 152. As another example, the first sub-cover 13 is provided with a limiting block 152, and the second sub-cover 14 is provided with a limiting groove 151. At least a portion of the limiting blocks 152 are disposed within the limiting groove 151, so that the first sub-cover 13 and the second sub-cover 14 are fixed together, and the first sub-cover 13 and the second sub-cover 14 are snap-fit ​​connected.

[0063] Therefore, this embodiment, by setting the limiting groove 151 and the limiting block 152, has a simple structure, facilitates the installation and disassembly of the first sub-cover 13 and the second sub-cover 14, facilitates the replacement and maintenance of the isolation membrane 20, and reduces the maintenance cost of the drainage decorative cover 1.

[0064] Furthermore, the limiting block 152 includes a first limiting part 1521 and a second limiting part 1522 connected to each other. The first limiting part 1521 is closer to the bottom of the limiting groove 151 than the second limiting part 1522, and the width of the first limiting part 1521 is greater than the width of the second limiting part 1522.

[0065] The arrangement direction of the first limiting part 1521 to the second limiting part 1522 is the same as the arrangement direction from the bottom wall of the limiting groove 151 to the opening of the limiting groove 151.

[0066] Optionally, when the limiting groove 151 is provided on the first sub-cover 13, the limiting groove 151 penetrates the side wall of the first sub-cover 13 and also penetrates the surface of the first sub-cover 13 facing the second sub-cover 14. Alternatively, when the limiting groove 151 is provided on the second sub-cover 14, the limiting groove 151 penetrates the side wall of the second sub-cover 14 and also penetrates the surface of the second sub-cover 14 facing the first sub-cover 13. The limiting block 152 can be installed into the limiting groove 151 from the side.

[0067] Therefore, by limiting the width of the first limiting part 1521 and the second limiting part 1522, this embodiment enables the limiting block 152 to be firmly fixed in the limiting groove 151, preventing the limiting block 152 from falling off from the bottom wall of the limiting groove 151 to the opening of the limiting groove 151, thereby improving the connection performance between the first sub-cover 13 and the second sub-cover 14.

[0068] Furthermore, along the arrangement direction from the second limiting portion 1522 to the first limiting portion 1521, the width of the first limiting portion 1521 gradually increases.

[0069] Optionally, the shape of the first limiting part 1521 is semi-circular, trapezoidal, etc. This embodiment reduces the difficulty of installing the limiting block 152 into the limiting groove 151 by further limiting the width of the first limiting part 1521.

[0070] Please refer to this as well. Figures 1-6 In yet another embodiment, the cover 10 is provided with an adhesive 40, which is used to bond the cover 10 to the component 50 to be installed.

[0071] The cover 10 is connected to the component 50 to be installed via an adhesive 40; in other words, the cover 10 and the component 50 are bonded together. Optionally, the cover 10 is provided with an adhesive groove for accommodating the adhesive 40.

[0072] Therefore, by providing the adhesive 40, this embodiment reduces the difficulty of installing and disassembling the drainage decorative cover 1, making it easier to replace and maintain the drainage decorative cover 1, and reducing the maintenance cost of the drainage decorative cover 1.

[0073] This application also provides a window assembly, the window assembly including a glass substrate and a drainage decorative cover as provided above in this application, the drainage decorative cover being disposed on the glass substrate.

[0074] Optionally, the window assembly can be used in vehicles, as well as other transportation equipment, transport equipment, engineering equipment, etc.

[0075] Optionally, the glass substrate can be a single pane of glass or laminated glass. Optionally, the material of the glass substrate can be soda-lime glass, high-alumina glass, lithium aluminum glass, or borosilicate glass, etc. Optionally, the glass substrate can be transparent glass or colored glass, heat-strengthened glass or tempered glass, or insulated glass, etc. Optionally, a transparent PC board can be used instead of a glass substrate.

[0076] This application also provides a vehicle, the vehicle including a body and a window assembly as described above, the window assembly being disposed at an opening in the body.

[0077] Optionally, the glass substrate can be used as side window glass, corner window glass, sunroof glass, rear windshield glass, etc. of a vehicle, and this embodiment does not limit it.

[0078] The window assembly and vehicle provided in this application, by adopting the drainage decorative cover provided above, can both drain water and prevent smoke leakage. This application sets an isolation membrane in the drainage decorative cover to divide the accommodating cavity into a first space and a second space. When the isolation membrane encounters water, the water presses down on the isolation membrane under the action of gravity, causing the isolation membrane to deform, so that the first space connects to the second space, thereby realizing drainage. When the isolation membrane encounters smoke, the smoke cannot press the isolation membrane, so the first space cannot connect to the second space, so the smoke cannot leak out from the drainage decorative cover, avoiding affecting the smoke leakage sealing test. Therefore, the drainage decorative cover provided in this application can both drain water and prevent smoke leakage.

[0079] The above description represents some embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
