Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle component technology, specifically to a water guiding device, a water channel assembly, and a vehicle. Background Technology
[0002] With the continuous development of vehicle technology, vehicle lightweighting has become an important solution for improving vehicle range. For example, in some hybrid or pure electric new energy vehicles, the use of lightweight materials such as plastic drainage systems to reduce overall vehicle weight is becoming increasingly common. However, due to the separate structural design of the lightweight drainage system assembly from the vehicle body, gaps can easily form between the assembly and the vehicle. This can easily allow dust from the bottom of the vehicle or abnormal odors from the engine compartment to enter the passenger compartment through the drainage channels of the drainage system assembly. Summary of the Invention
[0003] One objective of this invention is to provide a water guiding device to solve the problem in the prior art that dust from the bottom of a vehicle or abnormal odors from the engine compartment can easily enter the passenger compartment along the water guiding channel of the water channel assembly; a second objective is to provide a water channel assembly; and a third objective is to provide a vehicle.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0005] A water guiding device includes a drain pipe and a drain baffle. The drain pipe is connected to the water channel body in a water channel assembly and forms a snap-fit connection. The drain baffle is located on the end face of the drain pipe away from the water channel body and is rotatably connected to the drain pipe.
[0006] The drainage baffle contacts the surface of the drainage pipe under the action of gravity to form a seal on the drainage pipe. When the water flow in the water tank body is guided to the drainage pipe, the water flow impacts the drainage baffle to open the drainage pipe and drain water.
[0007] According to the above-mentioned technical means, by setting a drainage baffle at the drainage end of the drainage pipe to seal the water channel body, dust from the bottom of the vehicle or abnormal odors from the engine compartment can be prevented from entering the passenger compartment along the water channel body, thus improving the user's driving / riding experience. Furthermore, the drainage baffle self-closes the drainage pipe under gravity. When there is water to be drained in the water channel body, the water flow impacts the drainage baffle to automatically drain the water, eliminating the need for other structures to control the opening or closing of the drainage baffle, and also eliminating the need for other structures to connect the drainage pipe and the water channel body. Therefore, this utility model also has the advantages of simple structure and low production cost.
[0008] Furthermore, the end face of the drain pipe away from the main body of the water tank is set at an angle to the vertical direction, so that the drain baffle forms a pressure contact with the end face of the drain pipe away from the main body of the water tank under the action of gravity.
[0009] According to the above-mentioned technical means, since the end face of the drain pipe equipped with the drain baffle forms a certain angle with the vertical direction, i.e., it is inclined, a pressure contact can be formed between the drain baffle and the drain pipe. Therefore, the sealing stability of the drain baffle on the drain pipe can be improved.
[0010] Furthermore, the water guiding device also includes a sealing ring, which is located on the end face of the drain pipe near the main body of the water channel; wherein,
[0011] The sealing ring is squeezed to form a snap-fit connection between the drain pipe and the water tank body.
[0012] According to the above-mentioned technical means, the quick assembly and disassembly between the drain pipe and the water trough body can be achieved through the compression connection method of the sealing ring (one of the snap-fit methods). This not only simplifies the structure of the water guiding device, but also improves the assembly and disassembly efficiency between the water guiding device and the water trough body. Furthermore, it can further improve the airtightness of the water trough body and prevent external dust or odors from entering the passenger compartment along the connection between the water guiding device and the water trough body.
[0013] Furthermore, the edge of the longitudinal section along the length direction of the drain pipe is curved from the middle to the end near the main body of the water trough, and the height of the drain pipe gradually decreases from near the main body of the water trough to away from the main body of the water trough.
[0014] According to the above technical means, the curved arrangement of the drain pipe can facilitate the installation space of the drain baffle. The height of the drain pipe gradually decreases, which can gradually increase the flow velocity of the water flowing from the water tank body to the drain pipe. This makes it easier for the water to break through the drain baffle at a higher flow velocity when it reaches the drain baffle.
[0015] Furthermore, the water guiding device also includes a pin, which is disposed on the drain pipe, wherein one end of the drain baffle is connected to the pin.
[0016] According to the above-mentioned technical means, by using a pin shaft to form a rotating connection, the drainage baffle can be quickly installed on the drainage pipe, which improves the disassembly and assembly efficiency of the water guiding device and reduces the structural complexity of the water guiding device.
[0017] Furthermore, when the drainage baffle forms a surface contact with the drainage pipe, a portion of the drainage baffle extends to the radially outer side of the drainage pipe.
[0018] According to the above technical means, by increasing the contact area of the drainage baffle in contact with the drainage pipe, the sealing stability of the drainage baffle to the drainage pipe can be ensured during vehicle driving or when the vehicle is shaking.
[0019] Furthermore, the drain pipe and the drain baffle are both made of plastic material.
[0020] Based on the above technical means, the weight of the water guiding device can be further reduced, and the lightweight requirements of the water channel assembly can be met.
[0021] A water channel assembly includes a water channel body and a water guiding device as described in any of the above utility model claims, wherein the water channel body has a water guide port, and the drain pipe is connected to the water guide port.
[0022] A vehicle comprising the water trough assembly described above.
[0023] Furthermore, the water channel assembly is detachably connected to the vehicle body.
[0024] The above-mentioned technical means facilitate the disassembly and maintenance of the water tank assembly.
[0025] The beneficial effects of this utility model are:
[0026] (1) This utility model seals the water channel body by setting a drainage baffle at the drainage end of the drainage pipe, thereby preventing dust at the bottom of the vehicle or abnormal odors in the engine compartment from entering the passenger compartment along the water channel body, thus improving the user's driving / riding experience.
[0027] (2) This utility model uses a drainage baffle to self-close the drainage pipe under the action of gravity. When there is water to be discharged in the water tank body, the water flow impacts the drainage baffle to automatically drain the water. There is no need to set up other structures to control the opening or closing of the drainage baffle. It has the advantages of simple structure and low production cost. Attached Figure Description

[0033] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0034] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0035] With the continuous development of vehicle technology, vehicle lightweighting has become an important solution for improving vehicle range. For example, in some hybrid or pure electric new energy vehicles, the use of lightweight materials such as plastic drainage systems to reduce overall vehicle weight is becoming increasingly common. However, due to the separate structural design of the lightweight drainage system assembly from the vehicle body, gaps can easily form between the assembly and the vehicle. This can easily allow dust from the bottom of the vehicle or abnormal odors from the engine compartment to enter the passenger compartment through the drainage channels of the drainage system assembly.
[0036] Based on the aforementioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a drain pipe 1 and a drain baffle 2. By setting the drain baffle 2 at the drain end of the drain pipe 1 to seal the water channel body 5 in the water channel assembly, dust from the bottom of the vehicle or abnormal odors from the engine compartment can be prevented from entering the passenger compartment along the water channel body 5, thus improving the user's driving / riding experience. Furthermore, the drain baffle 2 self-closes the drain pipe 1 under gravity. When there is water to be drained in the water channel body 5, the water flow impacts the drain baffle 2 to automatically drain the water, eliminating the need for other structures to control the opening or closing of the drain baffle 2. Therefore, this utility model also has the advantages of simple structure and low production cost.
[0037] Reference Figure 1-2This utility model provides a water guiding device, which may include a drain pipe 1 and a drain baffle 2. The drain pipe 1 is connected to the water channel body 5 in the water channel assembly and forms a snap-fit connection. The drain baffle 2 is located on the end face of the drain pipe 1 away from the water channel body 5 and is rotatably connected to the drain pipe 1. Under the action of gravity, the drain baffle 2 contacts the surface of the drain pipe 1 to close it. When water flows from the water channel body 5 into the drain pipe 1, the water flow impacts the drain baffle 2, opening the drain pipe 1 to drain water.
[0038] In this embodiment of the invention, the water channel assembly is an important component of the vehicle, primarily used to guide and drain rainwater, preventing it from entering the vehicle body and sheet metal structure, including the vehicle's body structure and internal equipment. The water guiding device can be considered a part of the water channel assembly. The water guiding device forms a liquid path connection with the water channel body 5 in the water channel assembly and is located below the water channel body 5. When water flows into the water channel body 5, the water in the water channel body 5 is guided into the drain pipe 1. For example, the drain pipe 1 is detachably connected to the water channel body 5, and a drain baffle 2 is provided on the end face of the drain pipe 1 away from the water channel body 5. The drain baffle 2 is rotatably connected to the drain pipe 1, meaning that the drain baffle 2 can rotate freely around the drain pipe 1.
[0039] In some embodiments, a portion of the drainage baffle 2 may be extended along the length of the drainage pipe 1, thereby increasing the contact area with the drainage pipe 1, facilitating the rotational connection between the drainage baffle 2 and the drainage pipe 1, and improving the sealing stability of the drainage baffle 2 on the drainage pipe 1.
[0040] Under the influence of gravity, the drainage baffle 2 forms surface contact with the drainage end of the drainage pipe 1 (the end of the drainage pipe 1 away from the main body of the water trough 5), thus sealing off the drainage pipe 1. When rainwater in the main body of the water trough 5 flows into the drainage pipe 1, it has a certain flow velocity and impacts the drainage baffle 2, thereby opening the drainage baffle 2 and making the drainage channel in the drainage pipe 1 open, allowing the water accumulated in the main body of the water trough 5 to be discharged out of the vehicle through the drainage pipe 1.
[0041] Therefore, by sealing the water trough body 5 with a drainage baffle 2 at the drainage end of the drainage pipe 1, dust from the bottom of the vehicle or abnormal odors from the engine compartment can be prevented from entering the passenger compartment along the water trough body 5, thus improving the user's driving / riding experience. Furthermore, the drainage baffle 2 self-closes the drainage pipe 1 under gravity. When there is water to be drained in the water trough body 5, the water flow impacts the drainage baffle 2 to automatically drain the water. No other structure is needed to control the opening or closing of the drainage baffle 2, nor is any other structure needed to connect the drainage pipe 1 and the water trough body 5. Therefore, this invention also has the advantages of simple structure and low production cost.
[0042] An optional utility model embodiment, referring to Figure 1 and Figure 2 As shown, the end face of the drain pipe 1 away from the water tank body 5 is set at an angle to the vertical direction, so that the drain baffle 2 forms a pressure contact with the end face of the drain pipe 1 away from the water tank body 5 under the action of gravity.
[0043] In this embodiment of the invention, the end face of the drain pipe 1 furthest from the main body 5 of the water trough, i.e., the end face of the drain end of the drain pipe 1, is angled to the vertical direction (which can also be understood as the direction of gravity). This can be understood as the end face of the drain end of the drain pipe 1 being inclined. For example, the angle A between the end face of the drain end of the drain pipe 1 and the vertical direction can be an acute angle. This allows the drain baffle 2 to form pressure contact with the drain pipe 1 under the constraint of this angle and the action of gravity. Therefore, the sealing stability of the drain baffle 2 on the drain pipe 1 can be improved, preventing the drain baffle 2 from shaking and opening the drain pipe 1 during vehicle operation due to vibration.
[0044] In some embodiments, the angle formed between the drain pipe 1 and the vertical direction can be set between 30 and 60 degrees. For example, the angle A formed between the drain pipe 1 and the vertical direction can be 30 degrees, 45 degrees, or 60 degrees. Choosing these angle values facilitates the processing of the inclined surface on the drain pipe 1 and allows control over the area of the drain baffle 2, enabling the water flow to impact and open it. On the one hand, when the angle between the drain pipe 1 and the vertical direction is small, the pressure between the drain baffle 2 and the drain pipe 1 is small, making it easier for the drain baffle 2 to open the drain pipe 1 due to vibrations during vehicle operation. On the other hand, when the angle between the drain pipe 1 and the vertical direction is large, the structural area of the drain baffle 2 used to seal the drain end of the drain pipe 1 needs to be further increased, requiring a higher impact force from the water flow, and simultaneously increasing the weight and production cost of the drain baffle 2.
[0045] An optional utility model embodiment, referring to Figure 1 As shown, the water guiding device also includes a sealing ring 3, which is located on the end face of the drain pipe 1 near the water tank body 5. A fixed connection between the drain pipe 1 and the water tank body 5 is formed by pressing the sealing ring 3.
[0046] In this embodiment of the invention, the sealing ring 3 can be made of elastic materials such as silicone or rubber. The sealing ring 3 is located on the end face of the drain pipe 1 near the water flow body. In some embodiments, the sealing ring 3 can be sleeved on the outer side of the end face of the drain pipe 1, and then the drain pipe 1 is embedded in the water flow tank body 5 to form a compression connection. In other embodiments, the sealing ring 3 can be embedded on the inner side of the end face of the drain pipe 1, and then the drain pipe 1 is sleeved on the water flow tank body 5 to form a compression connection.
[0047] Therefore, the compression connection of the sealing ring 3 allows for quick assembly and disassembly between the drain pipe 1 and the water trough body 5. This not only simplifies the structure of the water guiding device but also improves the efficiency of assembly and disassembly between the water guiding device and the water trough body 5. Furthermore, it enhances the airtightness of the water trough body 5, preventing external dust or odors from entering the passenger compartment along the connection between the water guiding device and the water trough body 5. This further optimizes the product performance of the water guiding device.
[0048] An optional utility model embodiment, referring to Figure 1 As shown, the edge of the longitudinal section of the drain pipe 1 along its length direction is curved from the middle to the end near the water trough body 5, and the height of the drain pipe 1 gradually decreases from near the water trough body 5 to away from the water trough body 5.
[0049] In this embodiment of the present invention, the middle part of the drain pipe 1 can be understood as the portion within a preset distance range from the central radial line of the drain pipe 1 along its length direction. For example, the preset distance range could be 5 centimeters or similar. This can be selected by those skilled in the art based on the total length of the drain pipe 1, and is not limited in detail here. From the middle part to the end near the end of the water tank body 5, the edge of the longitudinal section along the length direction is curved. This can be understood as the edge of the drain pipe 1 in this section of the structure being obtained by smoothly connecting multiple curves with different curvatures. In other words, the drain pipe 1 is completely curved in this part. On the one hand, the curved arrangement of the drain pipe 1 facilitates the provision of installation space for the drain baffle 2. On the other hand, referring to... Figure 1As shown, the height H of the drain pipe 1 gradually decreases from near the water trough body 5 to away from it. This allows the water flow velocity to gradually increase during the flow of water through the drain pipe 1, facilitating the water flow to reach the drain baffle 2 at a higher velocity and ensuring rapid drainage of rainwater from the water trough body 5. Furthermore, the structural design of the drain pipe 1 reduces the vertical assembly space required, thereby improving the applicability of the water guiding device.
[0050] In other embodiments, the edge of the longitudinal section of the drain pipe 1, from its middle section to its end away from the main body 5 of the water tank, can be a straight line. That is, the outer diameter of the drain pipe 1 remains the same throughout this part of the structure. This facilitates the fitting of the drain baffle 2 with the outer surface shape of the drain pipe 1, forming a surface contact and allowing for a rotatable connection.
[0051] An optional utility model embodiment, referring to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the water guiding device may further include a pin 4, which is disposed on the drain pipe 1, wherein one end of the drain baffle 2 is connected to the pin 4.
[0052] In this embodiment of the invention, the pin 4 can pass through the exhaust pipe horizontally and through the drain baffle 2 to form a rotatable connection between the exhaust pipe and the drain baffle 2. Using the pin 4 to form a rotatable connection allows the drain baffle 2 to be quickly installed on the drain pipe 1, improving the assembly and disassembly efficiency of the water guiding device and reducing the structural complexity of the water guiding device.
[0053] An optional utility model embodiment, referring to Figure 2 and Figure 3 As shown, when the drainage baffle 2 forms a surface contact with the drainage pipe 1, a portion of the drainage baffle 2 extends to the radial outer side of the drainage pipe 1.
[0054] In this embodiment of the invention, a portion of the drainage baffle 2 extends radially outward from the drainage pipe 1. This can be understood as the baffle area of the drainage baffle 2 completely covering the circle formed by the outer diameter of the drainage pipe 1, with some baffle areas not covering the drainage pipe 1. By increasing the contact area of the drainage baffle 2 with the drainage pipe 1, the sealing stability of the drainage baffle 2 on the drainage pipe 1 can be ensured during vehicle operation or when the vehicle is vibrating.
[0055] In one optional embodiment of the utility model, the drain pipe 1 and the drain baffle 2 are both made of plastic material.
[0056] In this embodiment of the invention, the drain pipe 1 and the drain baffle 2 are both made of plastic material, which can further reduce the weight of the water guiding device and meet the lightweight requirements of the water channel assembly and the vehicle. Furthermore, the plastic drain baffle 2 has a lighter weight, allowing even a small flow of water to clear it, facilitating the timely discharge of water from the water channel body 5.
[0057] In summary, this utility model discloses a water guiding device, which may include a drain pipe 1 and a drain baffle 2. By setting the drain baffle 2 at the drain end of the drain pipe 1 to seal the water channel body 5 in the water channel assembly, dust from the bottom of the vehicle or abnormal odors in the engine compartment can be prevented from entering the passenger compartment along the water channel body 5, thus improving the user's driving / riding experience. Furthermore, the drain baffle 2 self-closes the drain pipe 1 under the action of gravity. When there is water to be drained in the water channel body 5, the water flow impacts the drain baffle 2 to automatically drain the water, without the need for other structures to control the opening or closing of the drain baffle 2. Therefore, this utility model also has the advantages of simple structure and low production cost.
[0058] Reference Figure 3 and Figure 4 As shown, this utility model embodiment also discloses a water channel assembly, which may include a water channel body 5 and a water guiding device as described in any of the above utility model embodiments, wherein the water channel body 5 is provided with a water guide port 501, and the drain pipe 1 is connected to the water guide port 501.
[0059] In this embodiment of the invention, the water channel assembly may include a front windshield water channel assembly and a rear pillar water channel assembly. The water guiding device is connected to the water guide port 501 on the water channel body 5 and is located below the water channel body 5. When water flows into the water channel body 5, the water in the water channel body 5 is guided into the drain pipe 1. For example, the drain pipe 1 is detachably connected to the water channel body 5. Thus, the water channel assembly may include a drain pipe 1 and a drain baffle 2. By setting the drain baffle 2 at the drain end of the drain pipe 1 to seal the water channel body 5 in the water channel assembly, dust from the bottom of the vehicle or abnormal odors in the engine compartment can be prevented from entering the passenger compartment along the water channel body 5, thereby improving the user's driving / riding experience. Furthermore, the drainage baffle 2 self-closes the drainage pipe 1 under the action of gravity. When there is water to be discharged in the water tank body 5, the water flow impacts the drainage baffle 2 to automatically drain the water. There is no need to set up other structures to control the opening or closing of the drainage baffle 2. Therefore, the water tank assembly also has the advantages of simple structure and low production cost.

The vehicle may include a drain pipe 1 and a drain baffle 2. By setting the drain baffle 2 at the drain end of the drain pipe 1 to seal the water channel body 5 in the water channel assembly, dust from the bottom of the vehicle or abnormal odors from the engine compartment can be prevented from entering the passenger compartment along the water channel body 5, thus improving the user's driving / riding experience. Furthermore, the drain baffle 2 self-closes the drain pipe 1 under gravity. When there is water to be drained in the water channel body 5, the water flow impacts the drain baffle 2 to automatically drain the water, eliminating the need for other structures to control the opening or closing of the drain baffle 2. Therefore, this invention also has the advantages of simple structure and low production cost, conforming to the trend of vehicle lightweighting and improving the vehicle's adaptability to various scenarios.
