DETAILED DESCRIPTION

[0028] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] New energy vehicles are equipped with exhaust devices and power batteries. As the power source of vehicle equipment, the power battery has a suitable working temperature of 10℃~20℃. When the vehicle is running, the power battery is working continuously and its temperature is high. It needs to be cooled down. The internal temperature of the vehicle is generally around 15℃ in winter and around 25℃ in summer. Therefore, in order to ensure the normal operation of the power battery, the working environment temperature of the power battery needs to be adjusted and controlled in time.

[0030] like Figure 1As shown, the exhaust system of a vehicle provided by an embodiment of the utility model includes a vehicle exhaust device 100 and a battery device 200, the vehicle exhaust device 100 is provided with a first exhaust port 110; the battery device 200 includes a battery pack 210, a shell 220 and a windshield component 230, the shell 220 is provided with an inner cavity 221 and an air inlet 222 and a second exhaust port 223 respectively connected to the inner cavity 221, the battery pack 210 is located in the inner cavity 221, the air inlet 222 is connected to the first exhaust port 110, the windshield component 230 covers the second exhaust port 223, one end of the windshield component 230 is rotatably connected to the outer wall of the shell 220, so that when the second exhaust port 223 is exhausted, the other end of the windshield component 230 is away from the second exhaust port 223 along the airflow direction.

[0031] The exhaust system of the vehicle of the embodiment of the utility model integrates the vehicle exhaust device 100 and the battery device 200. An inner cavity 221 is arranged inside the shell 220 of the battery device 200, and the battery pack 210 is arranged in the inner cavity 221. The vehicle exhaust device 100 discharges the exhaust gas in the vehicle through the first exhaust port 110. The air inlet 222 arranged in the shell 220 is connected to the first exhaust port 110. When the vehicle is running, the exhaust gas enters the inner cavity 221 through the first exhaust port 110 and is discharged to the outside of the shell 220 through the second exhaust port 223. The exhaust gas discharged by the vehicle is used to bring the heat in the inner cavity 221 out of the shell 220, so as to realize air cooling of the battery device 200, and cool the battery pack 210 and the inner cavity 221 environment inside the shell 220.

[0032] The utility model integrates the vehicle exhaust device 100 with the battery device 200, provides a new solution for the exhaust of new energy vehicles, optimizes the structure of the vehicle exhaust device 100 and the power battery, can ensure a certain positive pressure in the vehicle, and can make certain use of the exhaust gas in the vehicle. At the same time, for the whole vehicle, the integration of the vehicle exhaust device 100 and the battery device 200 also optimizes the space occupied by the roof equipment and reduces the weight of the whole vehicle.

[0033] In the exhaust system of the vehicle of the embodiment of the utility model, a windshield component 230 is provided on the outer wall of the shell 220 of the battery device 200, and the windshield component 230 blocks the second exhaust port 223. One end of the windshield component 230 is rotatably connected to the shell 220. In the process of exhaust gas passing through the inner cavity 221 and being discharged through the second exhaust port 223, the windshield component 230 is pushed along the airflow direction away from the second exhaust port 223 under the action of the exhaust gas flow, that is, the windshield component 230 rotates at a certain angle relative to the plane where the second exhaust port 223 is located. The size of the angle is adjustable under the influence of the wind force and air volume of the exhaust gas, thereby achieving the adjustable size of the opening formed by the windshield component 230 relative to the second exhaust port 223.

[0034] The exhaust gas enters the external environment through the second exhaust port 223 from the open port, and then the flow rate of the exhaust gas in the housing 220 can be adjusted without affecting the normal exhaust of the exhaust gas, thereby ensuring sufficient heat exchange and improving the cooling effect. Moreover, when the exhaust gas does not enter the inner cavity 221 of the housing 220, the windshield component 230 blocks the second exhaust port 223, which can prevent external impurities from entering the inner cavity 221 through the second exhaust port 223, polluting the interior of the housing 220, and hindering the operation of the battery pack 210, thereby ensuring that the inner cavity 221 is a relatively closed and clean environment.

[0035] In this embodiment, a plurality of battery packs 210 are arranged in the inner cavity 221, and there are gaps between each battery pack 210 and between the battery pack 210 and the shell 220 to form an exhaust gas circulation channel. When the pressure inside the vehicle is relatively high, the exhaust gas inside the vehicle enters the inner cavity 221 through the first exhaust port 110 of the vehicle exhaust device 100 and the air inlet 222 of the shell 220, flows between the exhaust gas circulation channels, dissipates heat for each battery pack 210, and is finally discharged from the second exhaust port 223.

[0036] According to one embodiment of the utility model, the wind shield component 230 includes at least one of an adjusting wind plate and a rubber pad. When the wind shield component 230 includes the adjusting wind plate and the rubber pad, the adjusting wind plate is rotatably connected to the outer wall of the shell 220, and the rubber pad is arranged on a side of the adjusting wind plate facing the second exhaust port 223; or, the wind shield component 230 includes a grille and a filter, the filter is arranged on the grille, and the grille is rotatably connected to the outer wall of the shell 220.

[0037] In one embodiment, the wind shielding component 230 can be designed as an adjustable wind plate or a rubber pad. The adjustable wind plate or the rubber pad is rotatably connected to the housing 220 at one end. The adjustable wind plate is relatively light in weight. In the process of exhaust gas flowing out from the inner cavity 221 to the outside, the adjustable wind plate can be pushed to rotate a certain angle to open the second exhaust port 223. The adjustable wind plate is subsequently rotated to cover and close the second exhaust port 223. The rubber pad needs to have a certain thickness to ensure that it has a certain weight. In the process of exhaust gas flowing out from the inner cavity 221 to the outside, the rubber pad can be pushed to rotate a certain angle to open the second exhaust port 223. The rubber pad needs to rotate by its own weight to cover and close the second exhaust port 223.

[0038] In one embodiment, the wind shielding component 230 may adopt a structural design of an adjusting air plate and a rubber pad, one end of the adjusting air plate is rotatably connected to the housing 220, and the rubber pad is attached to the side of the adjusting air plate facing the second exhaust port 223. During the process of exhaust gas flowing out of the inner cavity 221 to the outside, the adjusting air plate and the rubber pad may be pushed to rotate a certain angle to open the second exhaust port 223, and the adjusting air plate is subsequently rotated to cover and close the second exhaust port 223 again. At this time, the rubber pad can prevent the adjusting air plate from making abnormal noise when in contact with the housing 220. In other embodiments, the side of the adjusting air plate facing the second exhaust port 223 may also be covered with foam.

[0039] In one embodiment, the windshield component 230 may adopt a common structural design of a grille and a filter, one end of the grille is rotatably connected to the housing 220, and the filter may be covered on a side of the grille away from the second exhaust port 223. During the process of exhaust gas flowing out of the inner cavity 221 to the outside, the grille and the filter may be pushed to rotate a certain angle to open the second exhaust port 223, and the grille is subsequently rotated to cover the second exhaust port 223 again. At this time, the filter can prevent external impurities from entering the inner cavity 221 of the housing 220. In other embodiments, the grille may also be fixed at the second exhaust port 223, and the filter and the grille do not affect the exhaust of the second exhaust port 223.

[0040] In this embodiment, the rotational connection between the wind shielding component 230 and the housing 220 may be in the form of a hinge or a shaft connection.

[0041] According to an embodiment of the utility model, the outer wall of the shell 220 is further provided with a deflector 240, which is arranged on the outer side of the windshield component 230, and the deflector 240 is provided with an opening 241 facing downward.

After the exhaust gas passes through the inner cavity 221, the second exhaust port 223 is discharged into the deflector 240, and the deflector 240 gathers the exhausted exhaust gas and discharges it through the opening 241. The deflector 240 shields the entire block component from top to bottom to prevent rainwater from contacting the windshield component 230 or entering the inner cavity 221 of the shell 220 through the second exhaust port 223.

[0042] like Figure 2As shown, according to one embodiment of the utility model, the air deflector 240 is provided with a third exhaust port 242 on the side facing the second exhaust port 223, and the position of the third exhaust port 242 is staggered from the position of the second exhaust port 223. In this embodiment, the air deflector 240 is further provided with a third exhaust port 242, and the third exhaust port 242 is provided on the side of the air deflector 240 directly facing the second exhaust port 223 to assist in the exhaust gas entering the air deflector 240, but the position of the third exhaust port 242 is not directly facing the position of the second exhaust port 223, so as to prevent rainwater from falling on the wind shield component 230 and entering the second exhaust port 223 after entering the air deflector 240 through the third exhaust port 242, that is, the position of the third exhaust port 242 avoids the position of the second exhaust port 223 to prevent rainwater from splashing in.

The heat preservation member 250 is made of heat preservation material and can be a sheet structure, such as a heat preservation pad, foam, etc.

[0046] It is understandable that the second exhaust ports 223 are designed on two or four circumferential sides of the outer shell 224 , and each second exhaust port 223 is provided with a wind shielding component 230 to facilitate exhaust gas discharge.
