Description
Technical Field
[0001] This utility model belongs to the field of vehicles, and in particular relates to a water trough and a vehicle. Background Technology
[0002] To facilitate drainage during rainy weather, rear-engine highway vehicles such as buses and school buses, as well as front-engine vehicles, are equipped with drainage channels on their skin surfaces. These channels are adhered to the vehicle body and conform to the curvature of the body. The drainage channels are used to intercept rainwater from the windshield surface, rainwater blown up by the wipers, and rainwater left from the roof, keeping it in front of the driver's door and driver's window. This prevents rainwater from lingering on the driver's window and driver's door for extended periods, thus avoiding obstructing the driver's vision and ensuring driving safety.
[0003] like Figure 1 As shown, the existing water channel 1 includes an adhesive container 2 and a drainage channel 3. The adhesive container 2 is used to hold adhesive to bond the water channel 1 to the vehicle body, and the drainage channel 3 is used to drain water, with the opening of the drainage channel 3 facing forward. The water channel 1 also includes a guide section 5 located in front of the drainage channel 3. When the vehicle is in motion, the wind moves to both sides of the vehicle under the guidance of the guide section 5 to reduce the air resistance of the vehicle.
[0004] Among them, the water trough 1 is made by integral rolling or stamping process.
[0005] However, in the existing flow channel 1, such as Figure 1 As shown, the guide section 5 only partially blocks the drainage channel 3, and the front of the water channel 1 has a gap 4. When the vehicle is in motion, the wind will enter the drainage channel 3 through the gap 4, resulting in greater wind resistance and poorer fuel economy (the driving range is lower when the vehicle is an electric vehicle).
[0006] Meanwhile, the dimension of the water channel 1 in the width direction of the vehicle body (20 mm) is larger than the dimension in the length direction of the vehicle body (12 mm). When the drainage cross-sectional area of the drainage channel 3 in the water channel 1 remains unchanged, the larger dimension of the water channel 1 in the width direction of the vehicle body results in a larger vehicle width, a larger frontal area of the vehicle, and thus a larger wind resistance and poorer fuel economy (lower driving range when the vehicle is an electric vehicle).
[0007] For ease of understanding, those skilled in the art may also refer to the Chinese utility model patent with authorization announcement number CN209505869U and authorization announcement date of October 18, 2019.
[0008] The aforementioned Chinese utility model patent discloses a long-distance bus water trough. The opening of the drainage channel of the water trough faces forward, and no guide part is provided in front of the drainage channel. Therefore, the water trough has greater wind resistance and worse fuel economy (and even lower driving range when the vehicle is an electric vehicle).
[0009] The water trough is made of aluminum alloy profiles and has one or more weight-reducing and reinforcing holes to reduce its weight and enhance its structural strength. Utility Model Content
[0010] The purpose of this utility model is to provide a water flow channel to solve the technical problem of high wind resistance in existing water flow channels.
[0011] The purpose of this utility model is also to provide a vehicle to solve the technical problem of high wind resistance in existing vehicles.
[0012] To achieve the above objectives, the technical solution for the water tank provided by this utility model is as follows:
[0013] A water channel includes a drainage channel and a flow guide disposed in front of the drainage channel to block the drainage channel and reduce wind resistance. The flow guide completely blocks the drainage channel in the front-back direction to reduce wind resistance.
[0014] Furthermore, it also includes a glue container and an overflow container located directly in front of or behind the glue container, the overflow container being used to collect glue that overflows from the glue container.
[0015] Furthermore, the water channel is made using an extruded aluminum profile process, and includes weight-reducing reinforcing holes to reduce weight and increase structural strength.
[0016] Furthermore, the dimensions of the water channel are designed to ensure that the width in the left-right direction is less than the length in the front-back direction, in order to reduce wind resistance.
[0017] Furthermore, the width of the water trough is 8-15 mm, and the length of the water trough is 20-30 mm.
[0018] The beneficial effects of the water channel provided by this utility model are as follows: This utility model is an invention that changes the relationship between elements. The core difference between this utility model and the prior art is that in the prior art, the guide part only partially blocks the drainage channel, resulting in greater wind resistance of the water channel; while in this utility model, the guide part completely blocks the drainage channel in the front-to-back direction, thereby effectively reducing wind resistance and improving the vehicle's fuel economy or driving range.
[0019] To achieve the above objectives, the technical solution for the vehicle provided by this utility model is as follows:
[0020] A vehicle includes a body and water channels adhered to both sides of the body in the width direction. The water channels include drainage channels and a guide portion disposed in front of the drainage channels to block the drainage channels and reduce wind resistance. The guide portion completely blocks the drainage channels in the front-rear direction to reduce wind resistance.
[0021] Furthermore, it also includes a glue container and an overflow container located directly in front of or behind the glue container, the overflow container being used to collect glue that overflows from the glue container.
[0022] Furthermore, the water channel is made using an extruded aluminum profile process, and includes weight-reducing reinforcing holes to reduce weight and increase structural strength.
[0023] Furthermore, the body includes a windshield located at the front of the body and a driver's window and driver's door located on the side of the body. The windshield and the driver's window and driver's door are all transitioned by a topcoat. The water channel is bonded to the side of the topcoat that is away from the windshield and has a smaller curvature, in order to reduce the curvature of the water channel and its size in the width direction of the body, thereby reducing wind resistance.
[0024] Furthermore, the lower end of the water channel is flush with the lower end of the vehicle's windshield to reduce the water channel's wind-blocking area and wind resistance.
[0025] Furthermore, one end of the air deflector is positioned close to the vehicle body to reduce the gap between the air deflector and the vehicle body, thereby reducing wind resistance.
[0026] Furthermore, the dimension of the water channel in the width direction of the vehicle body is smaller than the dimension of the water channel in the length direction of the vehicle body.
[0027] The beneficial effects of the vehicle provided by this utility model are as follows: This utility model is an improved invention. It employs a completely new water channel, whose guide section completely blocks the drainage channel in the front-to-back direction, thereby effectively reducing wind resistance and improving the vehicle's fuel economy or driving range.

[0036] To address the problems in the background technology, the core inventive concept of this utility model is to completely block the drainage channel in the front-to-back direction of the air guide, thereby reducing wind resistance and improving the vehicle's fuel economy or driving range.
[0037] In this utility model, the front-to-back direction is the length direction of the vehicle body, the left-to-right direction is the width direction of the vehicle body, and the front of the vehicle body is in front of the rear of the vehicle body.
[0038] The present invention will be further described in detail below with reference to the embodiments.
[0039] Embodiments of the vehicle provided by this utility model:
[0040] Reference Figures 2-5 As shown, in a basic embodiment, the vehicle includes a body and water channels 1 bonded to both sides of the body in the width direction. The water channels 1 include drainage channels 3 and a guide section 2 disposed in front of the drainage channels 3 to block the drainage channels 3 and reduce wind resistance. The guide section 2 completely blocks the drainage channels 3 in the front-rear direction to reduce wind resistance. The water channels 1 can be manufactured using an extruded aluminum profile process.
[0041] The water channel 1 includes an adhesive container 6. During installation, adhesive must be placed in the adhesive container 6 to bond the water channel 1 to the vehicle body. During bonding, adhesive often overflows from the adhesive container 6, requiring manual scraping to remove the excess adhesive.
[0042] In a preferred embodiment, to save labor, such as Figures 2-3 As shown, the water tank 1 also includes an overflow tank 5 located directly in front of or behind the glue tank 6. The overflow tank 5 is used to collect the glue that overflows from the glue tank 6, thereby eliminating the need for manual glue scraping and saving labor.
[0043] In the above embodiment, by making the air guide 2 completely block the drainage channel 3 in the front-rear direction, it is possible to largely prevent wind from entering the drainage channel 3, thereby ensuring that most of the wind moves to both sides of the vehicle under the guidance of the air guide 2, reducing wind resistance, and thus improving the vehicle's fuel economy or driving range.
[0044] To further reduce wind resistance, in a preferred embodiment, the vehicle body includes a windshield 7 located at the front of the vehicle body and a driver's window 9 and driver's door located on the side of the vehicle body. The windshield 7 and the driver's window 9 and driver's door are all transitioned by a topcoat 8. A water channel 1 is bonded to the side of the topcoat 8 away from the windshield 7 and with a smaller curvature, so as to reduce the curvature of the water channel 1 and its size along the width direction of the vehicle body, thereby reducing wind resistance.
[0045] Specifically, compared to the placement of the water channel in the prior art, the water channel 1 in this embodiment is moved 30 mm backward (i.e. towards the rear of the vehicle) to place the water channel 1 on a part of the paint surface 8 with a smaller curvature. Since the curvature of the water channel 1 matches the curvature of the installation position, the curvature of the water channel 1 is also smaller, thereby effectively reducing the width of the water channel 1 in the vehicle width direction, reducing the windward area of the water channel 1, and reducing wind resistance.
[0046] In one embodiment, similar to existing drainage channels, the lower end of the drainage channel 1 is located below the windshield 7 to direct rainwater to a lower position as much as possible.
[0047] To further reduce wind resistance, in a preferred embodiment, such as Figures 4-5 As shown, the lower end of the water channel 1 is flush with the lower end of the windshield 7 of the vehicle body, in order to reduce the wind-blocking area and wind resistance of the water channel 1, thereby improving fuel economy or the driving range of the electric vehicle.
[0048] In one embodiment, there is a large gap between the foremost end (or innermost end) of the air deflector 2 and the vehicle body. Although the air deflector 2 can completely block the drainage channel 3 in the front-rear direction, wind will still move outward after entering the gap and reach the drainage channel 3. At this time, rainwater blown up by the wipers can enter the drainage channel 3 through this gap and be drained through the drainage channel 3.
[0049] To further reduce wind resistance, in a preferred embodiment, such as Figures 2-3 As shown, the air guide 2 not only completely blocks the drainage channel 3 in the front-rear direction, but also extends inward, so that one end of the air guide 2 (the frontmost end, or the innermost end) is arranged close to the vehicle body to reduce the gap between the air guide 2 and the vehicle body and to minimize the wind from entering the drainage channel 3, thereby reducing wind resistance and improving fuel economy or the driving range of the electric vehicle.
[0050] At this time, the rainwater blown up by the wipers will hit the front end of the guide section 2 and flow along the guide section 2, instead of entering the drain channel 3.
[0051] In addition to the large wind resistance caused by wind entering the drainage channel 3, the windward area (projected area in the front view) of the water channel 1 also affects the wind resistance of the water channel 1.
[0052] In the prior art, the width of the water channel 1 in the vehicle width direction is 20 mm, the length in the vehicle length direction is 12 mm, and the height is H (in mm). Therefore, the water channels 1 on both sides of the vehicle body increase the vehicle's height by 40H mm. 2 Its windward area is relatively small, resulting in significant wind resistance.
[0053] In this invention, on the one hand, by aligning the lower end of the drainage channel 1 with the lower end of the windshield 7 of the vehicle body, the height is reduced to h (in mm, and h < H). On the other hand, the width of the drainage channel 1 in the width direction (i.e., the left-right direction) is made smaller than the length of the drainage channel 1 in the length direction (i.e., the front-back direction). This reduces the width of the drainage channel 1 without changing the drainage cross-sectional area of the drainage channel 3 within it. For example, the width of the drainage channel 1 is 9.3 mm and the length is 25.8 mm, thus increasing the width of the drainage channels 1 on both sides of the vehicle body by only 18.6h mm. 2 The large frontal area can effectively reduce wind resistance and improve fuel economy or the driving range of electric vehicles.
[0054] Preferably, the width of the water trough 1 is 8-15 mm, for example 8 mm, 9.3 mm or 15 mm; the length of the water trough 1 is 20-30 mm, for example 20 mm, 25.8 mm or 30 mm; and the total cross-sectional area of the water trough 1 is generally 240 mm². 2 That is, the product of the length and width of the water tank 1 is generally 240 mm. 2 Of course, those skilled in the art can make the settings according to actual needs.
[0055] exist Figure 2 In the embodiment shown, the water channel 1 includes weight-reducing reinforcing holes 4 for reducing weight and increasing structural strength. On the one hand, it can reduce the overall vehicle weight, thereby further improving fuel economy or the driving range of the electric vehicle; on the other hand, it can improve the structural strength of the water channel 1.
[0056] exist Figure 3 In the embodiment shown, the water tank 1 does not include the weight-reducing reinforcement hole 4.
[0057] In actual vehicles, Figure 2 The water trough 1 shown is mainly used on rear-mounted road bikes. Figure 3 The water trough 1 shown is mainly used on front-engine vehicles. However, it is readily apparent to those skilled in the art that... Figure 2 The water trough 1 shown can also be used on front-engine vehicles. Figure 3 The water trough 1 shown can also be used on rear-mounted road vehicles.
[0058] After conducting gliding, power, and economy tests, the following conclusions were drawn: Figure 2 and Figure 3 The water tank 1 in the illustrated embodiment contributes 0.5 kWh / 100 km to economic improvement.
[0059] Therefore, the water trough 1 in this utility model can effectively improve fuel economy or driving range.
[0060] An embodiment of the water tank provided by this utility model:
[0061] like Figures 2-3 As shown, the water channel 1 includes a drainage channel 3 and a guide section 2 disposed in front of the drainage channel 3 to block the drainage channel 3 and reduce wind resistance. The guide section 2 completely blocks the drainage channel 3 in the front-rear direction to reduce wind resistance, thereby improving the fuel economy of the vehicle (or the driving range of the electric vehicle) when applied to a vehicle.
[0062] The water trough 1 in this utility model can be any type of water trough 1 in the vehicle embodiment of this utility model, and will not be described in detail here.
[0063] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some technical features, or organically combine different embodiments to create the embodiments shown in the accompanying drawings. Of course, those skilled in the art can also create other embodiments not shown in the accompanying drawings.
