These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0037] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0038] In the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0039] When a train is running fast on the line, a pair of counter-rotating longitudinal vortices will form at its tail. This pair of counter-vortices not only changes the air flow pattern in the streamlined area of ​​the rear car, but also directly affects the surface pressure distribution in this area, making the rear car prone to violent shaking, which in turn has an adverse effect on the smoothness of the train operation and the riding experience of passengers. In the related art, an even number of spoilers that can change the airflow structure of the rear are symmetrically set at the rear of the train, thereby reducing or eliminating the shaking of the rear car caused by the counter-vortices.

[0040] However, these spoilers achieve the raising or retracting of the vortex generators through a sliding control mechanism, which not only increases the complexity of the system but also has high spatial layout requirements, thereby increasing the difficulty and cost of train design.

[0041] The wake vortex spoiler device and train provided in the present application are intended to solve the above technical problems in the prior art.

[0042] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0043] See also Figures 1 to 3 The tail vortex spoiler device provided in the embodiment of the present application is applied to the rear of a train. The spoiler components 200 have an even number and are symmetrically arranged on both sides of the streamlined area of ​​the rear of the train.

[0044] The tail vortex spoiler device includes a vehicle shell 100 and a spoiler assembly 200. The vehicle shell 100 is provided with a mounting groove 110, and the spoiler assembly 200 is arranged in the mounting groove 110. The spoiler assembly 200 includes a spoiler 210, a folding frame 220 and a first driving member 230. The spoiler 210 is foldably arranged on the folding frame 220, the folding frame 220 is connected to the vehicle shell 100, and the first driving member 230 is connected to the folding frame 220; the first driving member 230 is configured to drive the folding frame 220 to unfold and fold, so that the spoiler 210 follows the folding frame 220 to unfold and extend out of the mounting groove 110 or fold into the mounting groove 110.

[0045] The car body 100 is the outer shell of the train, and a mounting groove 110 is provided on the surface of the car body for mounting and accommodating the spoiler assembly 200 .

[0046] The spoiler 210 changes the flow state of the airflow, guides the airflow to flow along a specific path, and reduces the generation of the tail vortex. It can be understood that the spoiler 210 has a certain flexibility and can be unfolded and folded. The folding frame 220 serves as a supporting structure of the spoiler 210 and is fixedly connected to the vehicle shell 100. Figure 4 and Figure 5 The folding frame 220 can drive the spoiler 210 to move synchronously through its folding and unfolding actions, so that the spoiler 210 can be unfolded when needed and can be compactly folded when not needed.

[0047] The first driving member 230 is connected to the folding frame 220, and is used to provide the power required to drive the folding frame 220 to unfold and fold. By controlling the start and stop of the first driving member 230, the spoiler assembly 200 can be flexibly controlled to adapt to different operating conditions and requirements.

[0048] Exemplarily, the spoiler 210 is made of a lightweight, high-strength material that can resist the effects of high-speed airflow without being easily deformed; for example, the spoiler 210 is a membrane structure, and when it is unfolded to its maximum extent, the spoiler 210 is in a taut state, so that the spoiler 210 forms a semi-rigid spoiler, thereby achieving the purpose of disturbing the airflow.

[0049] The folding frame 220 is hinged so that the spoiler 210 can be folded and unfolded along its length direction.

[0050] The first driving member 230 is a driving device such as an electric push rod, a stepping motor or a hydraulic pump, which is fixed inside the vehicle body 100 by bolts and connected to one end of the folding frame 220. If the first driving member 230 is an electric push rod, during the operation of the electric push rod, the folding frame 220 will be pushed to unfold, thereby driving the spoiler 210 to unfold synchronously and extend out of the installation slot 110; and when the electric push rod is reversely started, the folding frame 220 will be folded up, and the spoiler 210 will also be folded into the installation slot 110.

[0051] In specific implementation, the first driving member 230 is configured to drive the folding frame 220 to switch between the two states of unfolding and folding. When the first driving member 230 is started, the output end of the first driving member 230 pushes the folding frame 220 to unfold, thereby driving the spoiler 210 to unfold synchronously and extend out of the installation slot 110 to achieve airflow regulation; and when the first driving member 230 stops or reverses, the folding frame 220 will be folded up, and the spoiler 210 will also be folded into the installation slot 110 to avoid unnecessary interference with the overall performance of the train.

[0052] In the embodiment of the present application, the folding frame 220 is driven to unfold and fold by the first driving member 230, so that the spoiler 210 can follow the folding frame 220 to unfold and extend out of the mounting slot 110, so as to achieve the purpose of changing the flow state of the airflow; and the spoiler 210 can follow the folding frame 220 to fold into the mounting slot 110, effectively reducing the space occupied by the device when not in use, making the entire device more compact, and reducing the demand for space under the roof of the train. Therefore, the spoiler assembly 200 of the embodiment of the present application simplifies the overall structure of the device through the foldable spoiler 210, reduces the manufacturing cost, and at the same time, due to the reduced demand for space under the roof, it also reduces the difficulty of arranging the spoiler device and reduces the overall manufacturing cost of the train.

[0053] In some optional embodiments, see Figure 6 and Figure 7 The folding frame 220 includes a fixing member 221 and at least two folding rods 222. The fixing member 221 is fixedly connected to the vehicle shell 100. At least two folding rods 222 are arranged on the fixing member 221 in parallel and are movably connected to the fixing member 221. The spoiler 210 is fixedly arranged on the at least two folding rods 222, and the spoiler 210 has a fixed end 211, which is fixedly connected to the fixing member 221.

[0054] The fixing member 221 is a connecting member between the folding frame 220 and the car body 100, and the folding frame 220 is fixed to the car body 100 through the fixing member 221. The fixing member 221 can be fixedly connected to the car body 100 by bolts, welding or other suitable connection methods to ensure its stability and reliability during the operation of the train.

[0055] The folding frame 220 includes at least two folding rods 222, which are arranged in parallel and spaced apart on the fixing member 221, so that the spoiler 210 has a sufficient support area when unfolded while maintaining the compactness of the structure. The folding rods 222 and the fixing member 221 are connected movably, such as hinged or slidingly, so that the folding rods 222 can be folded and unfolded relative to the fixing member 221, thereby driving the spoiler 210 to move synchronously.

[0056] The spoiler 210 is arranged on each of the folding rods 222 arranged at intervals, so that the spoiler 210 can be orderly unfolded and folded during the unfolding and folding process, which is conducive to improving the stability and reliability of the spoiler 210. The fixed end 211 of the spoiler 210 is fixedly connected to the fixing member 221, which further increases the stability of the spoiler 210 and prevents it from accidentally falling off or being damaged during the unfolding or folding process.

[0057] The embodiment of the present application uses the folding rod 222 and the fixing member 221 so that the folding frame 220 can provide sufficient support area for the spoiler 210. The multiple folding rods 222 that are movably connected can enable the spoiler 210 to be flexibly unfolded and folded, which helps to reduce the space occupied by the device when not in use and improve the applicability of the spoiler assembly 200.

[0058] In some optional embodiments, the folding rod 222 is hingedly connected to the fixing member 221 , and at least two folding rods 222 can rotate relative to the fixing member 221 toward the notch of the installation groove 110 to unfold the spoiler 210 in a direction away from the fixing end 211 .

[0059] The folding rod 222 is connected to the fixing member 221 by a hinge, so that the folding rod 222 can rotate relative to the fixing member 221 toward the notch of the installation groove 110. When the folding rod 222 rotates, it will drive the spoiler 210 to move together, so that the spoiler 210 can be unfolded in the direction away from the fixing end 211. When the folding rod 222 rotates, the spoiler 210 will gradually unfold with the rotation of the folding rod 222. During this process, the spoiler 210 gradually changes from a compact folded state to an unfolded working state, thereby effectively reducing the vortex at the rear of the train and improving the aerodynamic performance of the train. Contrary to the unfolding process, when the folding rod 222 rotates in the opposite direction, the spoiler 210 will be folded accordingly. During this process, the spoiler 210 will return to a compact state, which is convenient for storage when not in use.

[0060] The folding frame 220 in this embodiment is unfolded in a rotating manner. Compared with the linear unfolding manner, the folding frame 220 can maintain a smaller volume before rotational unfolding, which is beneficial for the storage and transportation of the spoiler 210 in a limited space. In contrast, the linear unfolding requires a larger space to accommodate the unfolded folding frame 220 and the spoiler 210; at the same time, when the folding frame 220 is rotated and unfolded, each folding rod 222 can transfer the load to the fixing member 221, so that the folding frame 220 can more effectively disperse and withstand external forces, which helps to improve the stability and durability of the entire structure.

[0061] In some optional embodiments, see Figure 6 The folding frame 220 also includes a linkage member 223, at least two folding rods 222 are hingedly connected to the linkage member 223, and the output portion of the first driving member 230 is connected to one of the at least two folding rods 222, so that the at least two folding rods 222 can rotate synchronously.

[0062] The linkage 223 is connected to each folding rod 222 so that the folding rods 222 can form a whole and realize synchronous rotation. Thus, the folding frame 220 can maintain a more stable structural form during the unfolding and folding process, which helps to reduce vibration caused by structural instability and improve structural stability.

[0063] At the same time, the first driving member 230 only needs one driving source to control the unfolding and folding of the entire folding frame 220, which is helpful to simplify the device structure, reduce manufacturing costs, and reduce control difficulty.

[0064] In some optional embodiments, see Figure 6 The fixing member 221 is provided with a first guide groove 221b along the rotation direction of the folding rod 222, and the folding rod 222 is guided and matched with the first guide groove 221b. Through the first guide groove 221b, the folding rod 222 can rotate along a preset path during the rotation process, which is beneficial to improve the accuracy and stability of the rotation of the folding rod 222, reduce the friction and wear caused by the rotation, and extend the service life of the folding frame 220.

[0065] In some optional embodiments, see Figure 6 In the rotation direction of the folding rod 222, a limiting portion 221a is provided on one side of the fixing member 221 close to the fixing end 211, and at least two folding rods 222 can be folded in the limiting portion 221a.

[0066] The limiting portion 221a can limit the maximum position of the folding rod 222 during the rotation process, prevent the folding rod 222 from over-rotating and damaging the structure or affecting the function, and provide a stable support point for the folding of the folding rod 222, so that the folding rod 222 can remain compact and stable in the folded state. In this embodiment, by setting the limiting portion 221a on the fixing member 221, the folding rod 222 can maintain a more compact and stable shape in the folded state, reducing the occupied space and improving the space utilization. At the same time, the limiting portion 221a provides a stable support point for the folding rod 222, so that the folding frame 220 can maintain a certain strength and rigidity in the folded state, avoiding deformation or damage caused by external forces.

[0067] In some optional embodiments, see Figure 5 and Figure 7 In the arrangement direction of at least two folding rods 222, the folding rod 222 away from the fixed end 211 has a sealing surface 222a, and the sealing surface 222a matches the outer surface of the vehicle shell 100, wherein when the folding frame 220 is folded, the sealing surface 222a covers the notch of the mounting groove 110.

[0068] The sealing surface 222a matches the outer surface of the vehicle shell 100, that is, when the folding frame 220 is in the folded state, the sealing surface 222a can be closely attached to the outer surface of the vehicle shell 100, forming an effective sealing barrier to prevent external air, moisture, dust and other impurities from entering the interior of the mounting groove 110, and reduce the external wind force acting on other structural parts in the vehicle shell 100, thereby protecting the folding frame 220 and the vehicle shell 100 from damage. At the same time, the sealing surface 222a can also reduce the noise and vibration caused by the airflow passing through the gap, thereby improving the driving stability of the vehicle and the comfort of the passengers. In addition, because the sealing surface 222a matches the outer surface of the vehicle shell 100, the folding frame 220 can maintain a more compact and neat shape in the folded state, which is conducive to improving the overall aesthetics of the vehicle.

[0069] In some optional embodiments, see Figures 8 to 10 The tail vortex spoiler device also includes a limiting assembly 300, which includes a limiting member 310 and a second driving member 320. The limiting member 310 is hingedly connected to the groove edge of the installation groove 110, and the second driving member 320 is connected to the limiting member 310. The second driving member 320 can drive the limiting member 310 to rotate relative to the groove edge of the installation groove 110 so that the limiting member 310 at least partially covers the groove opening of the installation groove 110.

[0070] The stopper 310 can rotate relative to the groove edge within a certain range, so as to cover or open the notch. Since the stopper 310 at least partially covers the notch of the mounting groove 110, the spoiler assembly 200 is protected and restricted. When the folding frame 220 is in a folded state, the stopper 310 can completely or partially cover the notch to prevent external impurities from entering the interior of the mounting groove 110, and avoid the interference and obstruction caused by these impurities when the folding frame 220 is unfolded. At the same time, when the folding frame 220 needs to be unfolded, the stopper 310 can be rotated and opened to provide enough space for the unfolding of the folding frame 220. The second driving member 320 is used to drive the stopper 310 to rotate, control the rotation angle and speed of the stopper 310, so as to cover the notch and make way for the notch. Exemplarily, the second driving member 320 is a rotary motor or a stepping motor, and its output end drives the stopper 310 to rotate through a gear transmission.

[0071] When the blocking assembly 300 is used in scenes such as high-speed trains, airplanes and other transportation vehicles, the folding frame 220 and the mounting groove 110 need to be frequently unfolded and folded, and at the same time, a high sealing performance and structural stability need to be maintained. The covering of the blocking member 310 can further prevent external air, moisture, dust and other impurities from entering the mounting groove 110, thereby improving the sealing performance of the entire tail vortex spoiler device. The hinged connection of the blocking member 310 and the drive control of the second drive member 320 enable the blocking assembly 300 to maintain a high structural stability and reliability during the unfolding and folding process.

[0072] Therefore, in the embodiment of the present application, the hinged connection of the limiting member 310 and the driving control of the second driving member 320 help the limiting assembly 300 to maintain structural stability during the unfolding and folding process.

[0073] In some optional embodiments, the limit member 310 includes a limit plate 311 and a connecting seat 312, the limit plate 311 is connected to the connecting seat 312, the groove edge of the mounting groove 110 is provided with a second guide groove 111 extending along the rotation direction of the limit member 310, and the connecting seat 312 is linked and connected in the second guide groove 111.

[0074] The baffle plate 311 is used to cover the notch of the installation slot 110 or the notch area that cannot be sealed by the folding rod 222. Its shape, size and material need to be designed according to the actual application scenario and requirements to ensure that it can provide sufficient protection or limit when the folding frame 220 is unfolded and folded. The connecting seat 312 is a connecting component between the baffle plate 311 and the groove edge of the installation slot 110. The baffle plate 311 can be installed on the groove edge and drive the baffle plate 311 to rotate within a predetermined rotation angle. The connecting seat 312 can be connected to the baffle plate 311 through an articulated connection such as a bolt or a pin to form an integral structure.

[0075] The connecting seat 312 is connected in the second guide groove 111, and the second guide groove 111 guides and supports the connecting seat 312, so that the limit member 310 can move along a predetermined track when rotating, avoiding failure and damage caused by deviation from the track, which is beneficial to improving the stability and reliability of the limit member 310.

[0076] In some optional embodiments, a limiting step 112 is provided on the groove edge of the installation groove 110, and the limiting step 112 is located on the groove edge of the installation groove 110 close to the groove opening. When the limiting member 310 covers the groove opening of the installation groove 110, the limiting member 310 cooperates with the limiting step 112 in a limiting manner.

[0077] The limiting step 112 is used as a limiting point of the limiting member 310 when covering the notch. When the limiting member 310 rotates to the position covering the notch, the limiting member 310 contacts and matches the limiting step 112, thereby ensuring that the limiting member 310 can stably stay at the predetermined position and will not be easily moved or deviated due to external factors (such as wind force, vibration, etc.). It can be understood that the limiting step 112 is a shape that matches the contact surface of the limiting member 310 to ensure a close fit between the two.

[0078] When the stopper 310 rotates to the position covering the notch, it will come into contact with the limiting step 112. This contact can be sliding contact, rolling contact or static contact, depending on the design of the stopper 310 and the limiting step 112 and the requirements of the actual application scenario. During the contact process, the stopper 310 will be restricted and supported by the limiting step 112, thereby maintaining a stable posture.

[0079] The cooperation between the limiting step 112 and the limiting member 310 can effectively limit the movement range of the limiting member 310, ensuring that it always remains in the predetermined position. This limiting effect not only helps to prevent the limiting member 310 from deviating from the track due to external factors, but also improves the stability and reliability of the entire spoiler assembly 200 system.

[0080] The present application also provides a train, comprising a train body and the wake vortex spoiler provided in the above-mentioned embodiments, wherein the wake vortex spoiler is arranged on the train body. It can be understood that the train has the beneficial effects of the wake vortex spoiler of any of the above-mentioned embodiments, which will not be described one by one here.
