Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and in particular to a drainage cone, a drainage system and a vehicle. Background Art
[0002] The vehicle has a drainage system, for example, the front cabin gutter drainage system. The drainage function of the drainage system has an important impact on the water sealing performance of the vehicle. If the drainage performance of the drainage system is poor, water will accumulate in the drainage system and overflow into the vehicle, giving users a very bad experience.
[0003] The drainage system in the prior art usually uses a drainage cone for drainage. The drainage cone includes a drainage pipe and a cover plate. The cover plate can be rotatably installed on the drainage pipe. When there is no water flowing through, the cover plate is attached to the drainage outlet to cover the drainage outlet of the drainage pipe. When there is water flowing through, the water flow flushes the cover plate to drain the water.
[0004] However, slender leaves such as pine needles from the outside may enter the drainage system through surface openings in structures such as the vehicle's ventilation cover, and then enter the drain cone, causing blockage of the drain cone. Alternatively, water is easily adsorbed at the contact point between the drain port and the cover, and easily freezes in an environment with low temperatures, causing blockage of the drain cone and affecting the drainage performance of the drainage system. Utility Model Content
[0005] In view of this, the present application provides a drainage cone, a drainage system and a vehicle to solve the problem that the drainage cone is easily clogged in the prior art.
[0006] In order to achieve the above objectives, this application provides the following technical solutions:
[0007] A drainage cone, comprising:
[0008] A drainage pipe having a connected water inlet and a drainage outlet;
[0009] A cover plate is opposite to the drain port, a first end of the cover plate is connected to the drain pipe, and a second end of the cover plate has at least a preset gap between it and the drain port.
[0010] Optionally, the first end of the cover plate is rotatably connected to the drain pipe, and one of the drain outlet and the cover plate is provided with a limiting protrusion, and the limiting protrusion abuts against the other to support the cover plate so that there is at least the preset gap between the second end of the cover plate and the drain outlet.
[0011] Optionally, the limiting protrusion is provided at the drain outlet, and the end of the limiting protrusion facing the cover plate is an abutting end for abutting against the cover plate, and the abutting end is a pointed end.
[0012] Optionally, when the cover plate abuts the drain outlet, the distance between the contact position between the limiting protrusion and the cover plate and the first end of the cover plate is smaller than the distance between the contact position between the limiting protrusion and the cover plate and the second end of the cover plate.
[0013] Optionally, the limiting protrusion is provided at the drain outlet, and there are multiple limiting protrusions, the multiple limiting protrusions are distributed at intervals along the circumference of the drain outlet, and at least two limiting protrusions are distributed relatively to each other.
[0014] Optionally, the limiting protrusion is arranged at the drain outlet, and a buffer pad is provided on the surface of the cover plate facing the drain outlet, and the buffer pad is arranged corresponding to the limiting protrusion.
[0015] Optionally, the preset gap is 5-10 mm.
[0016] A drainage system comprises any one of the drainage cones described above.
[0017] Optionally, the drainage system further comprises a water flow trough, a side wall of which is provided with an air conditioning air inlet baffle, and the water flow trough is connected to the air conditioning air inlet of the vehicle through the air conditioning air inlet baffle.
[0018] A drainage hole is provided at the bottom of the water flow trough, and the drainage cone is connected to the drainage hole; or,
[0019] A drainage hole is provided on the side wall of the water flow trough, and the drainage cone is connected to the drainage hole.

[0021] In the embodiment of the present application, when there is no water flowing through the drain cone, pine needles or other slender fallen leaves that fall into the drain cone can be discharged through the preset gap to prevent accumulation at the drain outlet and blockage of the drain outlet. There is a preset gap between the second end of the cover plate and the drain outlet, so that the distance between the second end of the cover plate and the drain outlet is increased, and the water tension is not enough to make the water adsorbed between the cover plate and the drain outlet, thereby reducing the risk of water freezing between the cover plate and the drain outlet and causing the drain outlet to be blocked. It can be seen that the embodiment of the present application can solve the problem that the drain cone in the prior art is easy to be blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0040] like Figures 1 to 5As shown, the embodiment of the present application provides a drainage cone, which can be used in the drainage system of a vehicle. Of course, the drainage cone can also be applied to other equipment, such as a sewer pipe, etc. The provided drainage cone includes a drainage pipe 100 and a cover plate 200.
[0041] The drain pipe 100 has a connected water inlet 120 and a drain outlet 110. The cover plate 200 is opposite to the drain outlet 110, the first end 210 of the cover plate 200 is connected to the drain pipe 100, and there is at least a preset gap 300 between the second end 220 of the cover plate 200 and the drain outlet 110, so that a drainage gap is formed between the cover plate 200 and the drain outlet 110.
[0042] In the embodiment of the present application, when there is no water flowing through the drain cone, pine needles or other slender fallen leaves falling into the drain cone can be discharged through the preset gap 300 to prevent accumulation at the drain outlet 110 and blockage of the drain outlet 110. There is a preset gap 300 between the second end 220 of the cover plate 200 and the drain outlet 110, so that the distance between the second end 220 of the cover plate 200 and the drain outlet 110 is increased, and the water tension is not enough to make the water adsorbed between the cover plate 200 and the drain outlet 110, thereby reducing the risk of freezing of the water between the cover plate 200 and the drain outlet 110 and blocking the drain outlet 110. It can be seen that the embodiment of the present application can solve the problem that the drain cone in the prior art is easy to be blocked.
[0043] In addition, when the drain cone is used in the drainage system of the vehicle, a preset gap 300 is provided between the second end 220 of the cover plate 200 and the drain outlet 110, so that the drain cone can not only drain water through the preset gap 300, but also, to a certain extent, prevent small external animals such as snakes, insects, rats, ants, etc. from entering the drain cone through the drain outlet 110 and then entering the vehicle. At the same time, it can also, to a certain extent, prevent a large amount of odors such as carbon monoxide in the cabin and tire odors from entering the drain cone and the water gutter 600 through the drain outlet 110 and then entering the interior of the vehicle through the air-conditioning inlet.
[0044] In order to form a preset gap 300 between the cover plate 200 and the drain outlet 110, in an optional embodiment, the cover plate 200 can be fixedly connected to the drain pipe 100 by welding, screw connection, or clamping, and the cover plate 200 is maintained at an angle with a preset gap 300 between the second end 220 and the drain outlet 110. In this structure, the gap between the cover plate 200 and the drain outlet 110 is fixed and always the preset gap 300.
[0045] In another optional embodiment, the first end 210 of the cover plate 200 can be rotatably connected to the drain pipe 100, and when the cover plate 200 is not subjected to external force, the gap between the cover plate 200 and the drain outlet 110 is a preset gap 300. When water flows through, the water flow can impact the cover plate 200, increasing the gap between the cover plate 200 and the drain outlet 110. In this structure, the preset gap 300 is the minimum gap between the cover plate 200 and the drain outlet 110. When the water flow is large, the water flow can flush the cover plate 200, so that the gap between the cover plate 200 and the drain outlet 110 becomes larger, thereby achieving faster drainage.
[0046] Optionally, the drain pipe 100 may be provided with a mounting seat 130 , and the cover plate 200 may be rotatably mounted on the mounting seat 130 via a rotating shaft 400 .
[0047] In the case where the cover plate 200 can rotate, in order to make at least a preset gap 300 between the second end 220 of the cover plate 200 and the drain outlet 110. In an optional embodiment, one of the drain outlet 110 and the cover plate 200 may be provided with a limiting protrusion 111, and the limiting protrusion 111 may abut against the other to support the cover plate 200, so that at least a preset gap 300 is provided between the second end 220 of the cover plate 200 and the drain outlet 110. When the cover plate 200 is not subjected to external force, the limiting protrusion 111 abuts against the other to support the cover plate 200, so that there is a preset gap 300 between the second end 220 of the cover plate 200 and the drain outlet 110. When the cover plate 200 is impacted by water flow, the water flow flushes the cover plate 200, so that the limiting protrusion 111 is separated from the other, and the gap between the cover plate 200 and the drain outlet 110 is greater than the preset gap 300.
[0048] In this embodiment, the structure of the drainage cone is simple, and the drainage gap formed is stable and reliable.
[0049] In another optional embodiment, a guide groove may be provided on the drain pipe 100, and a guide protrusion may be provided at the first end 210 of the cover plate 200. The guide protrusion may extend into the guide groove, and when the cover plate 200 rotates relative to the drain outlet 110, the guide protrusion slides in the guide groove.
[0050] Along the extension direction of the guide groove, the guide groove has a first end and a second end. When the cover plate 200 is not subjected to external force, the guide protrusion abuts against the first end, and the first end supports the guide protrusion and then supports the cover plate 200, so that the positions of the cover plate 200 and the drain outlet 110 are relatively fixed, and the gap between the cover plate 200 and the drain outlet 110 is a preset gap 300. In this state, the angle between the cover plate 200 and the drain outlet 110 is minimized.
[0051] When a large water flow impacts the cover plate 200, the second end 220 of the cover plate 200 rotates away from the drain outlet 110, and the guide protrusion rotates along the guide groove toward the second end of the guide groove until the guide protrusion abuts against the second end of the guide groove. In this state, the angle between the cover plate 200 and the drain outlet 110 is the largest, and the gap between the second end 220 of the cover plate 200 and the drain outlet 110 is the largest.
[0052] In the embodiment where at least a preset gap 300 is provided between the second end 220 of the cover plate 200 and the drain outlet 110 by means of the limiting protrusion 111, the limiting protrusion 111 can be provided at the drain outlet 110, and the end of the limiting protrusion 111 facing the cover plate 200 is abutting end for abutting the cover plate 200, and the abutting end is a tip, and further, when the cover plate 200 abuts against the drain outlet 110, the contact between the tip of the limiting protrusion 111 and the cover plate 200 can be point contact. In this case, the contact area between the cover plate 200 and the drain outlet 110 can be reduced, and even if water is adsorbed at the contact position between the two, and the water adsorbed at the contact position freezes, the ice area is also very small, and it is difficult to cause blockage of the drain outlet 110.
[0053] The angle a of the tip of the limiting protrusion 111 can be 70-90°, for example 80°, and the angle b formed by the outer edge of the limiting protrusion 111 and the area of the second end 220 of the drain outlet 110 facing the cover plate 200 can be 135-155°, for example 145°.
[0054] The limiting protrusion 111 can be arranged at any position of the drain outlet 110 , for example, it can be arranged at the area opposite to the drain outlet 110 and the first end 210 of the cover plate 200 , or it can be arranged at the area adjacent to the drain outlet 110 and the second end 220 of the cover plate 200 .
[0055] In a preferred embodiment, when the cover plate 200 abuts against the drain outlet 110, the distance between the abutting position of the limiting protrusion 111 and the cover plate 200 and the first end 210 of the cover plate 200 is smaller than the distance between the abutting position of the limiting protrusion 111 and the cover plate 200 and the second end 220 of the cover plate 200, that is, the limiting protrusion 111 is disposed adjacent to the rotational connection between the cover plate 200 and the drain outlet 110. In this case, when the size of the limiting protrusion 111 is fixed, it is easier to form a larger preset gap 300, and the limiting protrusion 111 is not easy to block the discharge of pine needles or other small fallen leaves from the drain outlet 110.
[0056] The number of the limiting protrusions 111 may be one or more. When there are multiple limiting protrusions 111, the multiple limiting protrusions 111 may be distributed at intervals along the circumference of the drain outlet 110, and at least two limiting protrusions 111 are distributed relatively. In this case, the force on the cover plate 200 is more uniform, which can improve the position stability of the cover plate 200.
[0057] When the drainage cone in the embodiment of the present application is used in a vehicle, vibration may be generated during the driving of the vehicle, and the vibration may cause the cover plate 200 to shake. During the shaking process, the cover plate 200 may hit the drainage outlet 110, generate noise, and affect the user experience.
[0058] To this end, in an embodiment of the present application, a buffer pad 500 may be provided on the surface of the cover plate 200 facing the drain outlet 110. The buffer pad 500 may be a rubber pad. The buffer pad 500 may be arranged corresponding to the limiting protrusion 111. That is, the buffer pad 500 may be distributed in the area of the cover plate 200 used to abut the limiting protrusion 111, or the buffer pad 500 may also be distributed on the entire surface of the cover plate 200 facing the drain outlet 110.
[0059] In this case, the buffer pad 500 can reduce the noise generated when the cover plate 200 hits the drain outlet 110 .
[0060] The preset gap 300 may be 5-10 mm, such as 5 mm, 8 mm or 10 mm, along the direction from the cover plate 200 to the drain opening 110. Optionally, the drain opening 110 may be rectangular, circular or in other shapes.
[0061] like Figure 6 As shown, based on the above-mentioned drainage cone, an embodiment of the present application further provides a drainage system, which includes the above-mentioned drainage cone. Since the drainage system has the above-mentioned drainage cone, the beneficial effects of the drainage system brought by the drainage cone can be found in the above content and will not be repeated here.
[0062] The drainage system can be a front cabin water trough drainage system of the vehicle. The front cabin water trough drainage system can also include a water trough 600. The front cabin water trough drainage system is located downstream of the vehicle ventilation cover. The ventilation cover is provided with an opening. The external environment is connected with the water trough 600 through the opening on the ventilation cover. The side wall of the water trough 600 can be provided with an air-conditioning air inlet water baffle 700. The water trough 600 is connected with the air-conditioning air inlet through the air-conditioning air inlet water baffle 700, so that the external environment is connected with the vehicle interior environment through the ventilation cover, the water trough 600, the air-conditioning air inlet water baffle 700 and the air-conditioning air inlet in turn, thereby realizing the connection between the external environment and the interior of the vehicle.
[0063] The bottom of the water trough 600 may be provided with a drainage hole. Of course, in other optional embodiments, the drainage hole may also be provided on the side wall of the water trough 600. The drainage cone may be connected to the drainage hole and seal with the drainage hole, so that pine needles and other slender fallen leaves, rain and snow that enter the water trough 600 through the opening on the surface of the ventilation cover plate can be discharged out of the vehicle through the drainage cone to prevent water from accumulating in the water trough 600. The drainage cone in the embodiment of the present application is not easy to be blocked, and the risk of accumulated water flooding into the cockpit of the vehicle through the air conditioning inlet water barrier can be reduced.
[0064] The A-pillar sheet metal 800 of the vehicle (eg, the A-pillar inner sheet metal or the A-pillar reinforcement sheet metal) can form a portion of the groove side wall of the water flow groove 600 to simplify the structure of the vehicle.
[0065] In order to achieve the connection between the drain cone and the drain hole, in an optional embodiment, the drain pipe 100 of the drain cone can be directly welded to the hole wall of the drain hole, or, the drain pipe 100 of the drain cone can be welded to the outer wall surface of the water flow channel 600, and the water inlet 120 of the drain pipe 100 is arranged around the drain hole to connect the drain cone with the drain hole.
[0066] In another optional embodiment, the drain cone may further include a connecting cap 900, which may be snapped, welded, bonded, or screwed to the drain hole of the water trough 600 and connected to the drain pipe 100 to connect the drain cone to the drain hole.
[0067] Specifically, the connecting cap 900 can be a hollow tubular structure. One end of the connecting cap 900 can be clipped or bonded to the water inlet 120 of the drain pipe 100 to connect the connecting cap 900 and the drain pipe 100. The other end of the connecting cap 900 can be provided with a folded edge protruding radially outward. The connecting cap 900 can pass through the drainage hole and be clipped to the water flow trough 600 through the folded edge to achieve the connection between the drainage cone and the water flow trough 600, as well as the connection between the drainage cone and the drainage hole.
[0068] Based on the above-mentioned drainage system, an embodiment of the present application further provides a vehicle, which includes the above-mentioned drainage system. Since the vehicle has the above-mentioned drainage system, the beneficial effects brought by the drainage system to the vehicle can be found in the above content and will not be repeated here.
