[0061] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a carriage according to an embodiment of this application is shown. Figure 2 The diagram shows a partial structural schematic of the spoiler 2 in the carriage of an embodiment of this application, which reflects the angle of attack when the spoiler is in operation. Figure 1 The X direction is the direction of travel during vehicle movement.

[0062] At least one embodiment of this application discloses a vehicle body, including a body 1, a spoiler 2, a wind force detection element 3, and a drive mechanism 4. The spoiler 2 is rotatably connected to the rear of the body 1 and has a windward surface 211. A windward angle A is formed between the windward surface 211 and the outer wall of the body 1 along the direction of travel. The wind force detection element 3 is located outside the body 1 and is used to detect ambient wind force values. One end of the drive mechanism 4 is connected to the body 1, and the other end is connected to the spoiler 2. The drive mechanism 4 can drive the spoiler 2 to rotate. The ambient wind force value is configured as the control basis for the drive mechanism 4, and the drive mechanism 4 controls the rotation of the spoiler 2 according to the ambient wind force value to change the size of the windward angle.

[0063] According to the embodiment of this application, the drive mechanism 4 controls the rotation of the spoiler 2 based on the ambient wind force value to change the size of the windward angle, so that the spoiler 2 can change the degree of turbulence on the body 1 of the compartment according to different ambient wind force values, thereby reducing the wind resistance during vehicle movement, thereby reducing vehicle energy consumption and improving vehicle economy, maximum speed and handling stability.

[0064] See Figure 2 In some embodiments, the body 1 includes a body 11 and a door panel 12 rotatably connected to the rear of the body 11.

[0065] In some embodiments, the spoiler 2 includes a plate body 21 and a swing arm 22, with a windward surface 211 disposed on the plate body 21. When the spoiler 2 is installed on the door panel 12, the windward surface 211 is located on the side surface of the plate body 21 away from the door panel 12, and the windward angle refers to the angle formed between the windward surface 211 and the outer wall of the door panel 12 on the side along the driving direction.

[0066] When the ambient wind speed is high, the drive mechanism 4 drives the spoiler 2 to rotate, thereby reducing the angle of attack and making the spoiler surface more parallel to the vehicle's direction of travel. This increases the spoiler's turbulence and reduces wind resistance during vehicle movement. When the ambient wind speed is low, the drive mechanism 4 drives the spoiler 2 to rotate in the opposite direction, thereby increasing the angle of attack and making the spoiler surface more closely fitted to the outer wall of the door panel 12. This reduces the spoiler's turbulence.

[0067] See Figure 1 In some embodiments, the carriage also includes a controller 5, a battery pack 6, and a solar photovoltaic panel 7. The controller 5 is mounted on the carriage and is communicatively connected to the wind detection element 3 and the drive mechanism 4. The battery pack 6 is mounted on the carriage and connected to the controller 5 to provide power to the controller 5. The solar photovoltaic panel 7 is mounted on the outer wall of the carriage and connected to the battery pack 6. The solar photovoltaic panel 7 can convert solar energy into electrical energy and store the electrical energy in the battery pack 6.

[0068] Specifically, the solar photovoltaic panel 7 is installed on the top wall of the compartment 11, which can better absorb solar energy, improve the energy conversion efficiency of the solar photovoltaic panel 7, and provide power to the controller 5. It can be understood that the battery pack 6 can also be connected to the compartment body 1 and other vehicle components to provide power to the compartment body 1 and other components on the vehicle, such as providing power for the driving power of new energy vehicles, providing power for the lighting mechanism inside the vehicle, and providing power for the refrigeration mechanism inside the compartment body 1, etc., effectively utilizing the top space of the compartment body 11, so that the compartment body 1 and the vehicle can achieve the effect of energy saving.

[0069] See Figure 1In some embodiments, the body 1 has a receiving cavity 111, and the controller 5 and battery pack 6 are disposed on the top wall of the receiving cavity 111, close to the front of the vehicle. Specifically, the receiving cavity 111 is disposed within the body 11, and the door panel 12 can close the receiving cavity 111. The controller 5 and battery pack 6 are placed within the receiving cavity 111, so that the body 11 can provide protection for the controller 5 and battery pack 6. The controller 5 and battery pack 6 are disposed on the top wall of the receiving cavity 111, close to the front of the vehicle, so that the controller 5 and battery pack 6 are placed deep within the receiving cavity 111 and do not occupy the bottom wall of the receiving cavity 111. This reasonable layout improves the overall space utilization of the vehicle and facilitates the storage and handling of goods by operators within the receiving cavity 111.

[0070] See Figure 2 In some embodiments, a storage groove 121 is provided on the outer wall of the door panel 12. The drive mechanism 4 includes an electric push rod 41, one end of which is rotatably connected to the storage groove 121, and the other end is provided with a telescopic end 411, which is rotatably connected to the spoiler 2. Specifically, the electric push rod 41 is rotatably connected to the storage groove 121, providing installation space for the connection between the electric push rod 41 and the door panel 12. In addition, it can provide a certain storage effect for the electric push rod 41, so that at least part of the electric push rod 41 can be stored in the storage groove 121, reducing the space occupied by the electric push rod 41 between the plate 21 and the door panel 12. This allows the plate 21 of the spoiler 2 to fit more closely to the outer wall of the door panel 12 when the spoiler 2 is closed, making the structure of the vehicle body more compact when the spoiler 2 is closed.

[0071] See Figure 3 , Figure 3 This illustration shows a partial structural diagram of the spoiler 2 in the passenger compartment of one embodiment of this application when it is in the open position. In some embodiments, the spoiler 21 is connected to the drive mechanism 4, one end of the swing arm 22 is rotatably connected to the outer wall edge of the passenger compartment body 1 along the driving direction, and the other end is rotatably connected to the spoiler 21. Specifically, the spoiler 2 is rotatably connected to the door panel 12 of the passenger compartment body 1 via the swing arm 22, and the spoiler 2 is rotatably connected to the drive mechanism 4 via the spoiler 21.

[0072] In some embodiments, the swing arm 22 includes an arm body 221, a first connecting plate 222 and a second connecting plate 223. The first connecting plate 222 is fixed to the outer wall of the body 1. One end of the arm body 221 is rotatably connected to the first connecting plate 222. The second connecting plate 223 is fixed to the outer wall of the body 21. The other end of the arm body 221 is rotatably connected to the second connecting plate 223.

[0073] In some embodiments, one end of the plate 21 connected to the second connecting plate 223 is provided with a connecting end 214. The connecting end 214 is bent toward the side close to the outer wall of the door panel 12, so that when the spoiler 2 is in the open working condition, the connection between the windward surface 211 and the outer wall of the body 1 along the driving direction is smoother, reducing wind resistance.

[0074] In some embodiments, a third connecting plate 213 is provided on the outer wall of the plate 21, and the drive mechanism 4 is rotatably connected to the third connecting plate 213. When the drive mechanism 4 includes an electric push rod 41, the telescopic end 411 of the electric push rod 41 is rotatably connected to the second connecting plate 223.

[0075] In some embodiments, the spoiler 2 is provided with a closed operating condition and an open operating condition, and the drive mechanism 4 controls the spoiler 2 to switch between the closed operating condition and the open operating condition. See also... Figure 3 When spoiler 2 is in closed operation, its angle of attack is greater than or equal to the preset angle. (See reference...) Figure 4 and Figure 5 , Figure 4 A partial structural schematic diagram of the spoiler 2 in the carriage according to an embodiment of this application is shown when it switches from an open state to a closed state. Figure 5 A partial structural schematic diagram of the drive mechanism 4 housed in the storage slot 121 in a vehicle compartment according to an embodiment of this application is shown. When the spoiler 2 is in operation, its angle of attack is less than a preset angle.

[0076] In some embodiments, the preset angle can be set to 30 degrees. It is understood that the preset angle can be set to different angles depending on the different usage scenarios of the vehicle.

[0077] See Figure 3 and Figure 4 In some embodiments, a limiting block 212 is fixedly provided on the plate 21. When the spoiler 2 is in the open working condition, the limiting block 212 is used to abut against the outer wall of the arm 221, and the plate 21 and the arm 221 are locked relative to each other. The drive mechanism 4 drives the plate 21 and the arm 221 to rotate synchronously. Specifically, when the spoiler 2 is in the open working condition, the limiting block 212 abuts against the outer wall of the arm 221, and the plate 21 and the arm 221 are locked relative to each other. This means that when the telescopic end 411 of the electric push rod 41 in the drive mechanism 4 extends or retracts, the plate 21 and the arm 221 remain relatively fixed. The arm 221 drives the plate 21 to rotate relative to the door panel 12 to change the size of the windward angle.

[0078] See Figure 4 and Figure 5When the spoiler 2 switches from the open to the closed state, the drive mechanism 4 drives the plate body 21 to rotate, and the plate body 21 drives the limiting block 212 to separate from the arm body 221; the drive mechanism 4 continues to drive the plate body 21 and the arm body 221 to rotate together to the closed limit position. Specifically, when the spoiler 2 switches from the open to the closed state, the telescopic end 411 of the electric push rod 41 in the drive mechanism 4 retracts, driving the plate body 21 to rotate, and the plate body 21 drives the limiting block 212 to separate from the arm body 221. The arm body 221 and the plate body 21 also rotate relative to each other during the rotation until the telescopic end 411 retracts to the retraction limit position of the electric push rod 41, driving the arm body 221 to rotate to fit against the outer wall of the door panel 12, and at the same time driving the plate body 21 to rotate to fit against the outer wall of the door panel 12. At this time, the windward angle approaches 90 degrees.

[0079] See Figure 3 In some embodiments, the swing arm 22 further includes an elastic element 224 connected between the arm body 221 and the arm body 221, and the elastic force of the elastic element 224 drives the limiting block 212 to abut against the arm body 221.

[0080] In some embodiments, the elastic element 224 is configured as a torsion spring, which is sleeved on the rotation shaft between the arm body 221 and the plate body 21. One end of the torsion spring is fixedly connected to the arm body 221, and the other end is fixedly connected to the plate body 21. The limiting plate on the plate body 21 is driven to abut against the arm body 221, so that the plate body 21 and the arm body 221 in the spoiler 2 are locked more stably when the spoiler is in the opening condition.

[0081] See Figure 1 In some embodiments, a plurality of spoilers 2 are provided. At least one spoiler 2 is rotatably connected to the edge of the top wall of the body 1 to form a top spoiler mechanism. In some embodiments, at least one spoiler 2 is rotatably connected to the edge of the side wall of the body 1 to form a top spoiler mechanism.

[0082] In some embodiments, the wind detection element 3 is configured as a wind sensor, which is arranged at the front of the body 1. It is understood that the wind detection element 3 may also be configured as other elements capable of detecting wind.

[0083] See Figure 6 , Figure 6 This diagram illustrates the structure of a vehicle compartment door panel 12 when fully opened, according to an embodiment of this application. In some embodiments, a support 122 is fixedly mounted on the compartment body 11, and a hinge 123 connects the support 122 and the door panel 12. The door panel 12 is rotatably connected to the compartment body 11 via the hinge 123. The door panel 12 can rotate to the side of the compartment body 11, allowing the accommodating cavity 111 to be fully opened for easy loading and unloading of goods.

[0084] At least one embodiment of this application proposes a vehicle for disturbing traffic, including a front end and a passenger compartment as described in any of the above embodiments, the passenger compartment being connected to the rear of the front end, and a wind detection element 3 being disposed in front of the front end.

[0085] According to the vehicle of the embodiment of this application, the wind force detection element 3 can obtain the ambient wind force value more accurately, and the spoiler 2 can change the degree of disturbance to the body 1 more accurately according to different ambient wind force values, thereby reducing the wind resistance during vehicle movement, thereby reducing vehicle energy consumption and improving vehicle economy, maximum speed and handling stability.

[0086] See Figure 7 , Figure 7 A schematic flowchart of a turbulence control method according to an embodiment of this application is shown. At least one embodiment of this application proposes a turbulence control method, including a carriage and a controller 5 as described in any of the above embodiments, wherein the controller 5 is communicatively connected to a wind detection element 3 and a drive mechanism 4, respectively.

[0087] When the ambient wind force value is greater than or equal to the preset wind force threshold, the controller 5 sends an opening command to the drive mechanism 4, and the drive mechanism 4 controls the spoiler 2 to rotate to change the windward angle, so that the spoiler 2 switches to the open working condition.

[0088] When the ambient wind force value is less than the preset wind force threshold, the controller 5 sends a closing command to the drive mechanism 4. The drive mechanism 4 controls the spoiler 2 to rotate to change the windward angle, so that the spoiler 2 switches to the closed working condition.

[0089] In some embodiments, the preset angle can be set to 30 degrees. It is understood that the preset angle can be set to different angles depending on the different usage scenarios of the vehicle.

[0090] In some embodiments, the preset wind force threshold can be 40 N / m². The preset wind force threshold can be set to different values ​​according to different usage scenarios of the vehicle.

[0091] The aforementioned turbulence control method allows the spoiler 2 to more precisely adjust the degree of turbulence on the body 1 according to different environmental wind force values, thereby reducing wind resistance during vehicle movement, reducing vehicle energy consumption, and improving vehicle economy, maximum speed, and handling stability.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
