Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle parts manufacturing technology, and in particular to a drain pipe, a drain assembly, and a vehicle. Background Technology
[0002] A drainage system is typically installed between the engine compartment and the driver's cab of a vehicle. This system can quickly drain liquid from the windshield to ensure the safety of the vehicle while driving.
[0003] In the relevant technical solution, the drainage component includes a ventilation cover and drain pipes. The ventilation cover is positioned below the windshield along the width direction of the vehicle, and the drain pipes are located on both sides of the ventilation cover. Each drain pipe includes an inlet and an outlet. The inlet connects to the ventilation cover, and the outlet connects to the outside of the engine compartment. Liquid on the windshield slides down the ventilation cover and is then discharged outside the engine compartment through the drain pipes on both sides.
[0004] However, in range-extended vehicles, due to the large number of components in the engine compartment, there is less space left for the drainage pipe, resulting in a smaller diameter of the drainage outlet. When the drainage volume is large, the smaller drainage outlet makes the drainage speed of the drainage pipe slower. Utility Model Content
[0005] Therefore, embodiments of this application provide a drain pipe, a drain assembly, and a vehicle, which is beneficial for improving the drainage speed of the drain pipe.
[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0007] This application provides a drain pipe, including a body, a drain channel formed within the body, and an inlet and a outlet at each end of the body, both of which are connected to the drain channel.
[0008] At least one side wall of the main body is provided with an auxiliary drain outlet, which is connected to the drainage channel.
[0009] In this embodiment, by providing an auxiliary drain outlet on at least one side wall of the drain pipe body, when the drainage volume is large, the liquid in the drainage channel can be discharged simultaneously through the auxiliary drain outlet and the drain outlet, thereby improving the drainage speed of the drain pipe.
[0010] In one possible implementation of this application, the auxiliary drain outlet is disposed on the sidewall of the drain pipe facing the side panel of the engine compartment.
[0011] This embodiment of the application sets the auxiliary drain outlet on the side wall of the drain pipe facing the engine compartment, thereby preventing the liquid discharged through the auxiliary drain outlet from contacting the parts inside the engine compartment, which helps to extend the service life of the parts inside the engine compartment.
[0012] In one possible implementation of this application, a protrusion is provided on the side wall, and the height of the protrusion gradually increases from the water inlet to the drain outlet. The auxiliary drain outlet is located at the end of the protrusion away from the side wall.
[0013] This embodiment of the application provides a protrusion on the side wall and places the auxiliary drain outlet at the end of the protrusion away from the side wall, thereby facilitating the requirements of injection molding and reducing manufacturing difficulty. Furthermore, since the height of the protrusion gradually increases from the inlet to the outlet, it also allows for better guidance of liquid through the auxiliary drain outlet.
[0014] In one possible implementation of this application, a flexible cover plate is further included, which is disposed over the auxiliary drain outlet and is used to open to the side away from the auxiliary drain outlet.
[0015] Understandably, since the flexible cover can open or cover the auxiliary drain outlet, the two have relative first and second states. In the first state, the drainage volume in the drain pipe is small or no drainage is needed. At this time, the flexible cover is placed on the auxiliary drain outlet to cover it. This prevents gas from the engine compartment from entering the drain pipe through the auxiliary drain outlet, and then entering the passenger compartment through the ventilation cover and air conditioning system, thus improving passenger comfort. In the second state, the drainage volume in the drain pipe is large. At this time, the flexible cover can be opened to the side away from the auxiliary drain outlet, allowing liquid to be discharged simultaneously through both the auxiliary drain outlet and the main drain outlet, thereby increasing the drainage speed of the drain pipe.
[0016] This embodiment of the application incorporates a flexible cover plate. When the drain pipe is not draining, the flexible cover plate can be used to shield the auxiliary drain outlet, preventing gas from the engine compartment from entering the drain pipe and subsequently the passenger compartment, thus improving passenger comfort. Furthermore, the flexible cover plate can be opened to the side opposite to the auxiliary drain outlet. When the drainage volume is large, the flexible cover plate can be opened, allowing liquid to be discharged simultaneously through both the auxiliary and main drain outlets, thereby increasing the drainage speed of the drain pipe.
[0017] In one possible implementation of this application, at least one fixing post is provided on the side wall, the fixing post is located on the side of the auxiliary drain outlet facing the water inlet, and at least one fixing hole is provided on the flexible cover plate, the flexible cover plate is sleeved on the fixing post through the fixing hole.
[0018] This embodiment of the application achieves the installation and fixation of the flexible cover by sleeved on the fixed column, so that the flexible cover can be placed on the auxiliary drain outlet to prevent gas in the engine compartment from entering the drain pipe and then into the passenger compartment, thereby improving the comfort of driving and riding.
[0019] In one possible implementation of this application, the sidewall is further provided with two opposing limiting members, which are respectively disposed on both sides of the auxiliary drain outlet. Each limiting member includes a connecting part and a limiting part. The connecting part is connected to the sidewall, and the limiting part is inclined to the connecting part. The first end of the limiting part is connected to the connecting part, and the second end of the limiting part extends to the side of the flexible cover plate away from the auxiliary drain outlet.
[0020] In this embodiment, limiting members are provided on both sides of the flexible cover plate, with some of the limiting members located on the side of the flexible cover plate away from the auxiliary drainage outlet. This allows the limiting members to restrict the opening of the flexible cover plate and limit its installation, preventing the flexible cover plate from being washed off by liquid when the drainage volume is large.
[0021] In one possible implementation of this application, the flexible cover plate includes a silicone cover plate or a rubber cover plate.
[0022] In this application, either a silicone cover or a rubber cover can be selected based on actual needs. Silicone covers remain stable at higher temperatures, are less prone to deformation or melting, and are suitable for use in engine compartments. Rubber covers have excellent elasticity, can withstand greater deformation without breaking, and are also less expensive.
[0023] In one possible implementation of this application, at least one connecting part is further included, which is connected to the body, and the body is used to connect to the engine compartment through the connecting part.
[0024] In this embodiment, the drain pipe is connected and fixed to the engine compartment via a connecting part, thereby achieving the installation and fixation of the drain pipe.
[0025] This application embodiment also provides a drainage component, including a ventilation cover and a drainage pipe as described above, wherein the drainage pipe is disposed on both sides of the ventilation cover and the inlet of the drainage pipe is connected to the ventilation cover.
[0026] Because the drainage assembly in this embodiment uses the aforementioned drainage pipe, when the drainage volume is large, liquid can be discharged from the drainage pipe simultaneously through the auxiliary drainage port and the main drainage port, thereby increasing the drainage speed. Furthermore, due to the flexible cover, the auxiliary drainage port can be shielded when the drainage pipe is not draining, preventing gas from the engine compartment from entering the drainage pipe and subsequently the passenger compartment, thus improving passenger comfort.
[0027] This application also provides a vehicle that includes the drainage assembly described above.
[0028] The vehicle in this embodiment uses the aforementioned drainage components, which increases the drainage speed at the front of the vehicle, thereby improving driving safety and comfort. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0038] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0039] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0040] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0041] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0042] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0043] As described in the background section, in the related technical solutions, due to the large number of components in the engine compartment of the range-extended vehicle, the space left for the drainage pipe is small, resulting in a small diameter of the drainage outlet. When the drainage volume is large, the small drainage outlet makes the drainage speed of the drainage pipe slower.
[0044] In view of this, the present application aims to provide a drain pipe, a drain assembly, and a vehicle. By providing an auxiliary drain outlet on at least one side wall of the drain pipe body, when the drainage volume is large, the liquid in the drain channel can be discharged simultaneously through the auxiliary drain outlet and the drain outlet, thereby improving the drainage speed of the drain pipe.
[0045] The embodiments of this application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0046] This application provides a drain pipe, a drain assembly, and a vehicle to improve the drainage speed at the front of a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally have a front drainage assembly, which includes a ventilation cover and a drain pipe. The ventilation cover is located below the windshield along the width direction of the vehicle, and the drain pipes are located on both sides of the ventilation cover. The drain pipes include inlets and outlets; the inlets are connected to the ventilation cover, and the outlets are connected to the outside of the engine compartment. Liquid on the windshield slides down to the ventilation cover and is discharged to the outside of the engine compartment through the drain pipes on both sides.
[0047] Please refer to Figures 1-4 This application provides a drain pipe, including a body 100, a drain channel formed inside the body 100, and an inlet 101 and a drain outlet 102 respectively at both ends of the body 100, both of which are connected to the drain channel.
[0048] At least one side wall 110 of the main body 100 is also provided with an auxiliary drain outlet 103, which is connected to the drainage channel.
[0049] It is understood that, in this embodiment of the application, the auxiliary drain outlet 103 can be disposed on any one or more sidewalls 110 of the main body 100. One or more auxiliary drain outlets 103 can be disposed on the same sidewall 110. The auxiliary drain outlet 103 can be in a regular shape such as circular, square, or triangular, or it can be in an irregular shape. The specific location, number, and shape of the auxiliary drain outlet 103 can be determined according to actual needs.
[0050] Please refer to Figure 4 Because there are many components in the engine compartment, the drain outlet 102 of the drain pipe can only be designed as an approximately elliptical structure to increase the drainage area. However, this solution still cannot meet the needs when the drainage volume is large. Therefore, in this embodiment of the application, an auxiliary drain outlet 103 is provided on at least one side wall 110 of the drain pipe body 100. When the drainage volume is large, the liquid in the drainage channel can be discharged simultaneously through the auxiliary drain outlet 103 and the drain outlet 102, thereby improving the drainage speed of the drain pipe.
[0051] In one possible implementation, the auxiliary drain outlet 103 of this application embodiment is provided on the side wall 110 of the drain pipe facing the side plate of the engine compartment.
[0052] Understandably, the above structure allows the liquid discharged from the auxiliary drain 103 to flow to the side panel of the engine compartment and flow down the side panel of the engine compartment out of the engine compartment, preventing the liquid from coming into contact with the parts inside the engine compartment.
[0053] In this embodiment, by setting the auxiliary drain outlet 103 on the side wall 110 of the drain pipe facing the engine compartment, the liquid discharged through the auxiliary drain outlet 103 can be prevented from contacting the parts in the engine compartment, which is beneficial to extending the service life of the parts in the engine compartment.
[0054] Please continue to refer to Figure 1 and Figure 2 In this embodiment of the application, a protrusion 111 is provided on the side wall 110. The height of the protrusion 111 gradually increases from the water inlet 101 to the drain outlet 102. The auxiliary drain outlet 103 is located at the end of the protrusion 111 away from the side wall 110.
[0055] For example, the drain pipe of this application embodiment can be integrally molded by processes such as injection molding, and the protrusion 111 is provided to facilitate the requirements of injection molding and demolding.
[0056] This embodiment of the application provides a protrusion 111 on the side wall 110 and places the auxiliary drain 103 at the end of the protrusion 111 away from the side wall 110, thereby facilitating the fulfillment of injection molding requirements and reducing manufacturing difficulty. Furthermore, since the height of the protrusion 111 gradually increases from the inlet 101 to the outlet 102, the protrusion 111 can also better guide liquid through the auxiliary drain 103 for discharge.
[0057] Please continue to refer to Figure 1 and Figure 2 The drain pipe in this embodiment of the application also includes a flexible cover plate 200, which is disposed on the auxiliary drain outlet 103 and is used to open to the side away from the auxiliary drain outlet 103.
[0058] Understandably, since the flexible cover 200 can open or cover the auxiliary drain outlet 103, the two have relative first and second states. For example... Figure 1 As shown, in the first state, the drainage volume in the drain pipe is small or no drainage is needed. At this time, the flexible cover 200 is placed over the auxiliary drain port 103 to cover the auxiliary drain port 103. This prevents gas in the engine compartment from entering the drain pipe through the auxiliary drain port 103, and then entering the passenger compartment through the ventilation cover and air conditioning system, thus improving the comfort of the ride. Figure 2As shown, in the second state, when the drainage volume in the drain pipe is large, the flexible cover plate 200 can be opened to the side away from the auxiliary drain port 103, and the liquid can be discharged simultaneously through the auxiliary drain port 103 and the drain port 102, thereby increasing the drainage speed of the drain pipe.
[0059] This embodiment of the application, by providing a flexible cover 200, can cover the auxiliary drain outlet 103 when the drain pipe is not draining, thereby preventing gas from the engine compartment from entering the drain pipe and subsequently the passenger compartment, improving passenger comfort. Furthermore, the flexible cover 200 can open to the side opposite to the auxiliary drain outlet 103. When the drainage volume is large, the flexible cover 200 can be opened, allowing liquid to be discharged simultaneously through the auxiliary drain outlet 103 and the drain outlet 102, thus increasing the drainage speed of the drain pipe.
[0060] Please continue to refer to Figure 1 and Figure 2 In this embodiment of the application, at least one fixing post 112 is provided on the side wall 110. The fixing post 112 is located on the side of the auxiliary drain outlet 103 facing the water inlet 101. The flexible cover plate 200 is provided with at least one fixing hole, and the flexible cover plate 200 is sleeved on the fixing post 112 through the fixing hole.
[0061] For example, in this embodiment of the application, two or more fixing posts 112 can be provided simultaneously, thereby improving the stability of the connection between the fixing posts 112 and the flexible cover plate 200. The diameter of the fixing hole can be slightly smaller than that of the fixing post 112, and it is fitted onto the fixing post 112 by an interference fit, thereby improving the stability of the connection.
[0062] In this embodiment, the flexible cover 200 is fitted onto the fixed post 112, thereby achieving the installation and fixation of the flexible cover 200. This allows the flexible cover 200 to cover the auxiliary drain outlet 103, preventing gas from the engine compartment from entering the drain pipe and then into the passenger compartment, thus improving the comfort of the ride.
[0063] Furthermore, in this embodiment of the application, the side wall 110 is also provided with two opposing limiting members 113. The two limiting members 113 are respectively provided on both sides of the auxiliary drain outlet 103. The limiting member 113 includes a connecting part 1131 and a limiting part 1132. The connecting part 1131 is connected to the side wall 110, and the limiting part 1132 is inclined to the connecting part 1131. The first end of the limiting part 1132 is connected to the connecting part 1131, and the second end of the limiting part 1132 extends to the side of the flexible cover plate 200 away from the auxiliary drain outlet 103.
[0064] By way of example, the connecting portion 1131 and the limiting portion 1132 in this embodiment can be integrally formed by bending. The limiting portion 1132 and the connecting portion 1131 can be perpendicular to each other. The connecting portion 1131 can be fixed to the side wall 110 of the protrusion 111 by welding, bolting or other means.
[0065] In this embodiment, limiting members 113 are provided on both sides of the flexible cover plate 200. Some of the limiting members 113 are provided on the side of the flexible cover plate 200 away from the auxiliary drain outlet 103. Thus, the opening of the flexible cover plate 200 can be limited by the limiting members 113, and the installation of the flexible cover plate 200 can be limited to prevent the flexible cover plate 200 from being washed off by liquid when the drainage volume is large.
[0066] Optionally, the flexible cover plate 200 in this embodiment of the application includes a silicone cover plate or a rubber cover plate.
[0067] In this application, either a silicone cover or a rubber cover can be selected based on actual needs. Silicone covers remain stable at higher temperatures, are less prone to deformation or melting, and are suitable for use in engine compartments. Rubber covers have excellent elasticity, can withstand greater deformation without breaking, and are also less expensive.
[0068] Please continue to refer to Figure 1 and Figure 2 The drain pipe in this embodiment further includes at least one connector 300, which is connected to the body 100. The body 100 is used to connect to the engine compartment via the connector 300. The specific number and location of the connectors 300 in this embodiment can be set as needed.
[0069] For example, this embodiment provides two connectors 300, which are located on opposite sides of the main body 100. The connectors 300 can be provided with corresponding connection holes or connectors to facilitate connection and fixation with the engine compartment.
[0070] In this embodiment, the drain pipe is connected and fixed to the engine compartment via a connector 300, thereby achieving the installation and fixation of the drain pipe.
[0071] This application embodiment also provides a drainage component, including a ventilation cover and the aforementioned drainage pipe. The drainage pipe is disposed on both sides of the ventilation cover, and the water inlet 101 of the drainage pipe is connected to the ventilation cover.
[0072] Because the drainage assembly in this embodiment uses the aforementioned drainage pipe, when the drainage volume is large, liquid can be discharged from the drainage pipe simultaneously through the auxiliary drainage port 103 and the drainage port 102, thereby increasing the drainage speed. Furthermore, because a flexible cover 200 is provided, the auxiliary drainage port 103 can be covered when the drainage pipe is not draining, preventing gas from the engine compartment from entering the drainage pipe and subsequently the passenger compartment, thus improving passenger comfort.
[0073] This application also provides a vehicle including the above-described drainage assembly.
[0074] Because the vehicle in this embodiment uses the aforementioned drainage components, it can improve the drainage speed at the front of the vehicle while preventing gas from the engine compartment from entering the drainage pipe and then the passenger compartment, thus improving driving safety and comfort.
[0075] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
