[0063] Implementation methods of this application

[0064] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0065] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0066] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0067] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0069] As shown in Figures 1 to 18, according to a first aspect of this application, a vehicle body structure 100 is provided, including a vehicle body 20 and a first air duct 8; a passenger compartment 13 is provided on the vehicle body 20; the first air duct 8 is provided on the vehicle body 20 and located on the rear side of the passenger compartment 13, and a first air inlet 7 is provided at one end of the first air duct 8 near the passenger compartment 13, and a first air outlet 9 is provided at the other end of the first air duct 8 away from the passenger compartment 13.

[0070] Specifically, in some embodiments, by setting a first air duct 8 at the rear of the passenger compartment 13, the airflow flowing near the passenger compartment 13 during high-speed driving can be guided into the first air duct 8 through the first air inlet 7 and then discharged through the first air outlet 9, thereby preventing high-speed airflow from intruding into the passenger compartment from the passenger compartment 13 and improving the comfort of driving and riding.

[0071] In actual driving, the airflow passing near the passenger hatch 13, especially the airflow on both sides of the passenger hatch 13, usually enters the passenger compartment from the passenger hatch 13 and forms a backflow behind the driver's head. By setting the first air duct 8 on the rear side of the passenger hatch 13, this part of the airflow can be guided, effectively controlling the direction of the high-speed airflow of the passenger hatch 13, especially on both sides of the passenger hatch 13, reducing the turbulence of the airflow inside the passenger compartment, and improving the driving comfort and safety of the occupants in the passenger compartment.

[0072] Referring to Figures 1 and 2, the rear air intake of the rear air duct is positioned on the rear side of the passenger compartment, covering both sides of the front air intake. This allows the airflow on both sides of the passenger compartment and the airflow escaping from above to be drawn into the rear airflow duct through the rear air intake. The drawn-in air flows out through the rear air outlet, which can effectively reduce the problem of airflow backflow on the rear side of the open passenger compartment, reduce airflow turbulence inside the passenger compartment, and thus enhance cabin comfort.

[0073] Optionally, as shown in Figures 3 and 4, the vehicle body 20 includes a spoiler 15 disposed on the rear side of the passenger compartment 13. The spoiler 15 is located above the first air duct 8, and the first air inlet 7 is disposed facing the passenger compartment 13.

[0074] Specifically, the spoiler 15 can effectively reduce air resistance generated when the vehicle is driving at high speed, thereby improving the vehicle's driving stability. By placing the spoiler 15 above the first air duct 8 and positioning the first air inlet 7 facing the passenger compartment opening 13, the high-speed airflow near the passenger compartment opening 13 can be introduced into the first air duct 8 to the maximum extent, thereby improving the comfort of the passenger compartment.

[0075] Optionally, as shown in Figures 3 and 4, the vehicle body structure 100 also includes a roll cage 16 disposed on the rear side of the passenger compartment 13, the roll cage 16 forming a gap with the spoiler 15, and the first air duct 8 being at least partially located within the gap.

[0076] Specifically, the roll cage 16 is designed to prevent the occupants' heads from directly hitting the ground in the event of a rollover, thus providing protection. At least a portion of the first air duct 8 is placed within the gap formed by the roll cage 16 and the spoiler 15, which on the one hand improves the integration of the vehicle body structure 100, and on the other hand improves the vehicle's safety performance.

[0077] Optionally, as shown in Figures 3 to 4 and Figure 19, at least a portion of the peripheral wall of the first air duct 8 is attached to the lower wall of the spoiler 15 and the upper wall of the roll cage 16.

[0078] Specifically, in some embodiments, at least a portion of the peripheral wall of the first air duct 8 is abutted against the lower wall of the spoiler 15 and the upper wall of the roll cage 16, meaning that the lower wall of the spoiler 15 and the roll cage 16 can mutually enclose each other to form at least a portion of the first air duct 8, improving the integration and structural reusability of the vehicle body structure 100. Furthermore, based on the operating characteristics of the spoiler 15, the first air duct 8 is more conducive to guiding the high-speed airflow near the passenger compartment 13.

[0079] Optionally, as shown in Figures 3 to 4 and Figure 19, a guide surface 30 is formed on the roll cage 16, which is configured to direct airflow to the first air inlet 7.

[0080] Specifically, in some embodiments, the guide surface 30 provided on the roll cage 16 can guide the high-speed airflow near and on both sides of the crew compartment 13 into the first air inlet 7, thereby improving the guiding effect of the first air duct 8.

[0081] Optionally, as shown in Figures 3 to 4 and Figure 19, the first air inlet 7 includes a first sub-air inlet 71 and a second sub-air inlet 72 spaced apart along the width direction of the vehicle body 20 (refer to the Y direction in Figure 2), and the first sub-air inlet 71 and the second sub-air inlet 72 are arranged in a V-shape.

[0082] Specifically, in some embodiments, the arrangement of the first sub-air inlet 71 and the second sub-air inlet 72 can improve the airflow on both sides of the passenger compartment 13 and the airflow escaping from above, drawing it into the first air duct 8 from the first air inlet 7, while also achieving a guiding effect and improving the vehicle's appearance.

[0083] Optionally, as shown in Figures 3 to 4 and Figure 19, the guide surface 30 includes a first guide surface 31 configured to guide the air to the first sub-inlet 71 and a second guide surface 32 configured to guide the air to the second sub-inlet 72.

[0084] Specifically, the first sub-air inlet 71 and the second sub-air inlet 72 are respectively provided with the first guide surface 31 and the second guide surface 32, so that the airflow on both sides of the crew compartment 13 can be guided to the corresponding sub-air inlets, thereby achieving fine control of the airflow.

[0085] Optionally, as shown in Figure 10, a first fan 10 is provided in the first air duct 8, and the air outlet of the first fan 10 faces the first air outlet 9.

[0086] Specifically, in some embodiments, the first fan 10 is positioned to accelerate the suction effect of the first air duct 8 on the airflow overflowing from both sides and above the occupant hatch 13, thereby improving the airflow guiding effect. More specifically, the first fan 10 can be positioned close to the first air outlet 9.

[0087] Optionally, as shown in Figures 9 and 10, a first cover plate 11 is provided at the first air outlet 9. The first cover plate 11 has an open state and a closed state. In the open state, the first cover plate 11 can open the first air outlet 9, and in the closed state, the first cover plate 11 can close the first air outlet 9.

[0088] Specifically, in some embodiments, when the first cover 11 is closed, it can prevent the first air vent 9 from being directly exposed to the outer surface of the vehicle body structure 100, protecting the internal mechanisms and electronic components as well as the overall aesthetics of the vehicle. When the first cover 11 is open, it can also allow the occupants to better experience the open passenger compartment.

[0089] In some embodiments, the opening and closing of the first cover 11 can be achieved by a fourth drive member 12, which can be a motor to improve automation control. Alternatively, the opening of the first cover 11 can be either an upward-flipping mechanism or a sliding switch; this application does not impose any limitations on this.

[0090] Optionally, as shown in Figures 1 and 2, multiple passenger hatches 13 are provided along the width direction of the vehicle body 20, and multiple first air ducts 8 are provided, with the multiple first air ducts 8 corresponding to the multiple passenger hatches 13.

[0091] Specifically, in practical applications, vehicles can typically be equipped with multiple driver and passenger seats, and each driver and passenger seat has a corresponding first air duct 8 at its occupant hatch 13, ensuring a comfortable driving and riding experience for all occupants. Corresponding to the conventional arrangement of the occupant hatch 13, multiple first air ducts 8 are usually arranged along the width of the vehicle body 20.

[0092] Optionally, as shown in Figures 1 and 2, the vehicle body structure 100 also includes a second air duct 2, which is located on the front side of the passenger compartment 13, and has a second air inlet 1 at the end away from the passenger compartment 13 and a second air outlet 3 at the end close to the passenger compartment 13.

[0093] Specifically, in some embodiments, the second air duct 2 is configured so that when the vehicle is traveling at high speed, the airflow can flow into the second air duct 2 through the second air inlet 1 and flow out through the second air outlet 3 and merge with the high-speed airflow flowing over the front hood 14, so as to avoid the high-speed airflow intruding into the passenger compartment, thereby improving the driving comfort of the passenger compartment and preventing the high-speed airflow from blowing directly on the head of the split unit.

[0094] Optionally, as shown in Figures 1 and 2, the vehicle body 20 also includes a front hood 14, which is located in front of the passenger hatch 13, and the second air duct 2 is located below the front hood 14.

[0095] Specifically, in some embodiments, the second air duct 2 is located below the front hood 14, which facilitates airflow guidance and makes the structure of the front of the vehicle more reasonable, thus improving the vehicle's aesthetics.

[0096] Optionally, as shown in Figures 1 to 2 and Figure 5, the second air inlet 1 is positioned facing the front of the vehicle body 20.

[0097] Specifically, during high-speed driving, the airflow speed at the front of the vehicle is relatively high. By setting the second air inlet 1 in front of the vehicle body 20, the airflow speed entering the second air duct 2 from the second air inlet 1 is higher, thereby improving the guiding ability of the airflow flowing out of the second air duct 2 to the direct airflow, preventing the airflow from intruding into the passenger compartment, and improving the comfort of driving and riding.

[0098] Optionally, as shown in Figures 1 to 2 and Figure 5, the second air inlet 1 is located at the front bumper position of the vehicle body 20.

[0099] Specifically, in some embodiments, the second air inlet 1 can be located below the vehicle's headlights or at the front bumper, where the airflow velocity is higher, which helps to increase the velocity of the airflow entering the second air duct 2.

[0100] Optionally, as shown in Figures 1 and 2, the second air outlet 3 is located on the side of the front hood 14 near the crew compartment 13.

[0101] Specifically, in some embodiments, the second air outlet 3 is located on the side of the front hood 14 near the passenger compartment 13, which can maximize the guidance of the airflow blowing directly onto the heads of the occupants, thereby improving driving comfort and safety. The angle between the normal direction of the second air inlet 1 and the front-rear wind direction of the vehicle body 20 is acute, in order to increase the air intake velocity.

[0102] Optionally, as shown in Figures 1 to 2 and Figure 5, the second air outlet 3 is located at the edge of the front hatch 14 near the crew hatch 13.

[0103] Specifically, by placing the second air outlet 3 at the edge near the passenger compartment opening 13, it is possible to avoid interference from other structures of the vehicle body 20 with the direction of the airflow from the second air outlet 3, which is conducive to the fine control of the airflow.

[0104] Optionally, as shown in Figures 7 and 8, the cross-sectional area of ​​the second air duct 2 gradually decreases along the air guiding direction.

[0105] Specifically, in some embodiments, by gradually reducing the cross-sectional area of ​​the second air duct 2 along the air guiding direction, the speed of the airflow passing through the second air outlet 3 is increased, which facilitates the effective control of the direction of the high-speed airflow by the second air duct 2.

[0106] Optionally, referring to Figures 11 and 12, the cross-section of the second air outlet 3 is a fan-shaped structure, and the width of the fan-shaped structure at the end away from the crew compartment 13 is smaller than the width at the end closer to the crew compartment 13.

[0107] Specifically, in some embodiments, the cross-section of the second air outlet 3 is set as a fan-shaped structure, and the large opening of the fan-shaped structure faces the side of the passenger compartment opening 13, so that the airflow ejected from the second air outlet 3 merges with the high-speed airflow to form a wide-angle flow direction, thereby expanding the protection range of the passenger compartment, preventing airflow from blowing into the passenger compartment to a greater extent, and improving the comfort and safety of the passenger compartment.

[0108] Optionally, as shown in Figure 4, a wind direction regulator 6 is provided at the second air outlet 3, and the wind direction regulator 6 is set to adjust the air outlet direction of the second air outlet 3.

[0109] Specifically, in some embodiments, the airflow regulator 6 can adjust the orientation of the second air outlet 3 according to parameters such as the actual operating speed of the vehicle, so as to match the speed of the high-speed airflow flowing over the front hood 14 in real time, making the second air duct 2 manage the high-speed airflow more reasonably, and ensuring that the high-speed airflow can be effectively prevented from intruding into the passenger compartment at any vehicle speed and attitude, thereby ensuring the comfort and safety of the driver and passengers.

[0110] In addition, the second air duct 2, which guides high-speed airflow through airflow, not only improves the comfort of the passenger cabin, but also allows the vehicle body structure to abandon the traditional roof, frame and windshield structures and adopt a completely open cabin design, solving the problem of obstructed lateral vision for drivers and passengers and improving the passenger cabin's view and driving safety.

[0111] Optionally, as shown in Figures 11 and 12, the wind direction adjuster 6 includes a first driving member 61 and an air guide structure 62. The air guide structure 62 is movably disposed at the second air outlet 3, and the first driving member 61 is configured to drive the air guide structure 62 to rotate.

[0112] Specifically, in some embodiments, the air guide structure 62 is rotated by the drive of the first drive member 61, so that the orientation of the second air outlet 3 can be adjusted to a suitable position to converge with the high-speed airflow. The first drive member 61 can be a motor, which can be connected to the vehicle's control module to achieve integrated control.

[0113] Optionally, as shown in Figures 11 and 12, the air guiding structure 62 is a grille structure, which divides the second air outlet 3 into multiple sub-air outlets 63.

[0114] Specifically, in some embodiments, the air guide structure 62 is designed as a grille structure, which allows the second air outlet 3 to be divided into multiple sub-air outlets 63, enabling precise control of high-speed airflow and improving the comfort of the passenger cabin.

[0115] Optionally, the vehicle body structure 100 also includes a control module and a detection device connected to the control module, and the control module is connected to the first drive member 61; the detection device is configured to detect the vehicle's operating speed, and the control module is configured to control the operating state of the first drive member 61 based on the detection results of the detection device.

[0116] Specifically, in some embodiments, by setting up a detection device and a control module, the operating state of the first drive component 61 can be matched with the vehicle's operating speed. The operating state of the first drive component 61 can include parameters such as start-up, shutdown, and operating speed. Through the control module, the operating state of the first drive component 61 can be matched with the detection structure to adjust the orientation of the second air outlet 3 in real time, thereby improving the comfort of the passenger compartment in various vehicle states.

[0117] Optionally, the second air duct 2 is configured as a flexible structure near the second air outlet 3.

[0118] Specifically, in some embodiments, the structure placed near the second air outlet 3 may be made of a flexible material, so that the position near the second air outlet 3 is a flexible structure, so as to facilitate the adjustment of the direction of the airflow regulator 6 for the orientation of the second air outlet 3.

[0119] Optionally, as shown in Figure 8, a second fan 4 is provided in the second air duct 2, and the air outlet of the second fan 4 faces the second air outlet 3.

[0120] Specifically, in some embodiments, the second fan 4 can accelerate the airflow speed in the second air duct 2. When the vehicle is at a low speed, the first fan can run at a low speed or not run at all, so as to reduce the power of the first fan 10 and save energy.

[0121] Optionally, as shown in Figures 1 to 4, the vehicle body 20 includes a front hood 14 and a second cover 5 disposed between the front hood 14 and the passenger hatch 13, the second cover 5 being configured to open or close the second air vent 3.

[0122] Specifically, in some embodiments, when the second cover 5 is closed, the second air outlet 3 can be hidden beneath the second cover 5 to effectively prevent rainwater or debris from entering the second air duct 2, thus avoiding any impact on the mechanical or electronic structures within the second air duct 2 and preventing human-caused damage, thereby improving the reliability of high-speed airflow control. When the second cover 5 is open, on the one hand, the second air outlet 3 can perform airflow management, improving the comfort of the passenger compartment; on the other hand, it also allows passengers to experience the feel of an open cockpit.

[0123] Optionally, as shown in Figures 1 to 4 and Figures 13 to 15, the second cover plate 5 is a split structure. In the open state, the split structures can be separated to avoid the second air outlet 3. In the closed state, the split structures can be joined together to close the second air outlet 3.

[0124] Specifically, in some embodiments, the second cover plate 5 is configured as a split structure, which facilitates the adaptation design of the second cover plate 5 and its individual control.

[0125] Optionally, as shown in Figures 13 to 15, the second cover plate 5 includes a first sub-cover plate 51 and a second sub-cover plate 52. The first sub-cover plate 51 is located in front of the second sub-cover plate 52. In the open state, the first sub-cover plate 51 can be folded upward to a set angle, and the second sub-cover plate 52 can be moved backward to avoid the second air outlet 3. In the closed state, the first sub-cover plate 51 can be joined with the second sub-cover plate 52 to close the second air outlet 3.

[0126] Specifically, in some embodiments, the upward folding design of the first sub-cover 51 provides an auxiliary lifting effect on high-speed airflow when the second cover 5 is in the open state, helping the passenger compartment avoid direct airflow and enhancing aerodynamic flow efficiency. The forward and backward movement of the second sub-cover 52 ensures that, when open, it does not affect the airflow exiting the second air outlet 3, improving the reliability of airflow management. The second sub-cover 52 can also be designed to open from both sides; the specific design can be tailored to actual needs, and this application does not impose any limitations on this.

[0127] The folding of the first sub-cover 51 and the movement of the second sub-cover 52 can be achieved by the second drive component 53 and the third drive component 54, respectively, thereby improving the control accuracy and reliability of the first sub-cover 51 and the second sub-cover 52.
