Detailed ways

The embodiments of the present application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present application are described in detail below.

The all-terrain vehicle 100 according to an embodiment of the present application is described below with reference to FIGS. 1 to 2.

As shown in FIG. 1, the all-terrain vehicle 100 according to the embodiment of the present application includes: a frame 10, an engine 20, an exhaust pipe 30, a guard plate, and a wind deflector 40.

As shown in Figure 1, the frame 10 determines the shape of the car and the size of the internal space of the frame 10. Almost all parts are arranged in the frame 10; the engine 20 is arranged in the frame 10, which can be arranged in the car The middle position inside the frame 10 is connected with other parts to realize the function of energy conversion. The exhaust pipe 30 is arranged in the frame 10, one end of which is connected to the engine 20 and located at the rear side of the engine 20, and the other side is connected to the main cylinder of the muffler to realize the exhaust function. The guard plate is installed in the frame 10, and the guard plate is located on both sides of the engine 20, and the guard plate can protect the engine 20 on both sides of the engine 20.

In one implementation, as shown in FIG. 2, the wind deflector 40 is arranged on at least one guard plate, and it has a forward air outlet and a rear air outlet, and the forward air outlet of the wind deflector 40 faces the driving direction of the all-terrain vehicle 100 , The rear air outlet of the wind deflector 40 faces the exhaust pipe 30. Since the exhaust pipe 30 works and its temperature is relatively high, the exhaust pipe 30 needs to be cooled, and the guard plate limits the cooling of the exhaust pipe 30 to a certain extent. Therefore, the method of setting the air deflector 40 is adopted to set the air deflector 40 It is arranged on at least one guard plate, so that when the all-terrain vehicle 100 is driving, natural wind can be blown in from the forward air outlet, and blown to the exhaust pipe 30 through the rear air outlet, so as to realize the natural cooling of the exhaust pipe 30 purpose.

Therefore, by adopting the arrangement scheme of designing the wind deflector 40 on the guard plate, when the all-terrain vehicle 100 is traveling, the flowing natural wind will be blown to the exhaust pipe 30 through the wind deflector 40, which can effectively speed up the exhaust. The heat dissipation of the air pipe 30 effectively reduces the temperature of the exhaust pipe 30.

According to a specific embodiment of the present application, as shown in FIG. 1, the wind deflector 40 is arranged in a cylindrical shape and is arranged obliquely on the guard plate. The forward air outlet of the wind deflector 40 is located in front and above the rear air outlet. The windshield 40 is arranged obliquely, which can facilitate the natural wind to blow in during the driving of the all-terrain vehicle 100. The forward air outlet of the wind deflector 40 is located above the rear air outlet, which makes it easier for the natural wind to blow from the front inlet to the rear air outlet. Thereby, it blows toward the exhaust pipe 30, thereby achieving the purpose of cooling the exhaust pipe 30. Moreover, the obliquely arranged wind deflector 40 can make reasonable use of the space around the guard plate, and can prevent it from interfering with other components. Specifically, the extension direction of the wind deflector 40 is inclined with respect to the horizontal plane.

According to a specific embodiment of the present application, as shown in FIG. 1, the air inlet area of the forward air outlet of the wind deflector 40 is larger than the air outlet area of the rear air outlet. The opening direction of the forward air outlet of the wind deflector 40 is the driving direction of the all-terrain vehicle 100, and its opening is forward. The larger the opening of the forward air outlet of the wind deflector 40, the larger the air inlet area; the rear of the wind deflector 40 The opening direction of the air outlet faces the exhaust pipe 30, and the opening of the rear air outlet of the air guide 40 is smaller than the opening of the forward air outlet of the air guide 40. By setting the opening of the rear air outlet of the air deflector 40 to be smaller than the opening of the forward air outlet of the air deflector 40, the flowing natural wind can be blown to the exhaust pipe 30 more concentratedly, so as to realize the rapid cooling of the exhaust pipe 30 .

Further, the cross-sectional area of the wind deflector 40 shows a decreasing trend in the direction from the forward air outlet to the rear air outlet. That is, along the direction from the forward air inlet of the air guide 40 to the rear air inlet, the cross-sectional area of the air guide 40 gradually decreases. As a result, natural wind can flow smoothly in the air guide 40, so that the temperature of the exhaust pipe 30 can be lowered better.

According to a specific embodiment of the present application, as shown in FIGS. 1 and 2, the wind deflector 40 includes a plurality of plates connected in the circumferential direction, the upper and lower plates of the wind deflector 40, the plates on the left and right sides, and the The upper and lower plates and the two inclined plates arranged between the left and right plates are connected to each other. The wind deflector 40 is arranged as a plurality of plates connected in sequence in the circumferential direction. On the one hand, it can ensure a sufficient air inlet volume, and on the other hand, it can make reasonable use of the space around the guard plate to prevent it from interfering with other components.

According to a specific embodiment of the present application, the wind deflector 40 is an integrally molded part, and the material of the wind deflector 40 can be various, which may be a metal integrally formed part, or a plastic integrally formed part, and of course, it may be a strength One-piece molded parts of other materials that meet the requirements. Arranging the wind deflector 40 as an integrally formed part can reduce manufacturing complexity and time and cost on the one hand, and can increase the strength on the other hand to avoid the wind deflector 40 from being unable to be used normally due to excessive wind.

According to a specific embodiment of the present application, the all-terrain vehicle 100 further includes a bracket. The wind deflector 40 is connected to the protector through the bracket. Through the connection of the bracket, the wind deflector 40 is more firmly fixed on the protector to prevent When the all-terrain vehicle 100 is running fast, the wind deflector 40 is blown off by the flowing natural wind.

According to a specific embodiment of the present application, there are two wind deflectors 40, and the two wind deflectors 40 are symmetrical with respect to the frame 10, which are respectively arranged on the guard plates on the left and right sides of the engine 20, and two wind deflectors 40 are arranged. The wind-receiving area of the exhaust pipe 30 can be increased, and the temperature of the exhaust pipe 30 can be lowered more quickly. Of course, only one wind deflector 40 can also be provided.

According to a specific embodiment of the present application, a flaring edge is provided at the forward tuyere, and the flaring edge is set on the periphery of the forward tuyere. The flaring edge can be set as a sheet-like structure surrounding the periphery of the forward tuyere, of course, it can also be set to other structure. The setting of the flared edge can increase the air inlet area, so that more natural wind can be blown into the wind deflector 40, thereby ensuring the air inlet volume.
