Description

Technical Field

[0001] The present invention relates to the technical field of spoiler equipment manufacturing, in particular to a spoiler device and a train. Background Art

[0002] As a method of flow field regulation and aerodynamic optimization, train spoilers have the advantages of simple structure and strong applicability. In terms of aerodynamic drag reduction, their working principle is similar to that of ailerons on an airplane or the tail wing on a car. They reduce resistance by changing the characteristics of the airflow flowing through the train, thereby improving stability and energy efficiency. In terms of auxiliary braking, spoilers mainly help slow down the vehicle by increasing the frontal area and increasing air resistance. However, with the development trend of diversified appearance of high-speed trains, the fixed spoilers used in existing technologies can no longer meet the aerodynamic optimization requirements under high-speed driving conditions. Therefore, the development of spoiler devices that can be dynamically adjusted according to the operating status has become an inevitable trend. Summary of the Invention

To this end, the present invention provides a spoiler device, wherein the spoiler strip can be raised or lowered according to the different states of the train, thereby achieving better spoiler drag reduction or auxiliary braking effect.

[0039] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0040] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] As a method of flow field regulation and aerodynamic optimization, train spoilers have the advantages of simple structure and strong applicability. In terms of aerodynamic drag reduction, their working principle is similar to that of ailerons on an airplane or the tail wing on a car. They reduce resistance by changing the characteristics of the airflow flowing through the train, thereby improving stability and energy efficiency. In terms of auxiliary braking, spoilers mainly help slow down the vehicle by increasing the frontal area and increasing air resistance. However, with the development trend of diversified appearance of high-speed trains, the fixed spoilers used in existing technologies can no longer meet the aerodynamic optimization requirements under high-speed driving conditions. Therefore, the development of spoiler devices that can be dynamically adjusted according to the operating status has become an inevitable trend.

[0043] To solve this problem, a first embodiment of the present invention provides a spoiler device 1000 for use on trains. The specific structure and function of the spoiler device 1000 provided by the embodiment of the present invention will be further described below with reference to text and drawings.

[0044] Reference Figures 1 to 5According to the first embodiment of the present invention, a spoiler device 1000 is provided, comprising a base 100 and a lifting assembly. The base 100 is provided with a mounting cavity 110 for mounting the lifting assembly. A slot 120 is provided on the top of the base 100, connecting to the mounting cavity 110 and facilitating the raising and lowering of the spoiler strip 330. The lifting assembly comprises a drive mechanism 200 and multiple lifting mechanisms 300. The drive mechanism 200 includes a compressor 210, multiple air inlet pipes 220, and multiple electronic valves 230. The compressor 210 is connected to each of the multiple air inlet pipes 220 to provide air for the telescopic airbags 320. Each air inlet pipe 220 is equipped with an electronic valve 230. By controlling the opening and closing of the electronic valve 230, the air inlet pipe 220 can be opened and closed, thereby controlling the inflation and deflation of the telescopic airbags 320. The lifting mechanism 300 includes a telescopic sleeve 310, a telescopic airbag 320, and a spoiler strip 330. The telescopic sleeve 310 is fixed on the base 100, providing a guide for the lifting and lowering of the spoiler strip 330. The spoiler strip 330 is slidably connected to the outer periphery of the telescopic sleeve 310, and the upper end is passed through the straight edge 120. The telescopic airbag 320 is arranged in the spoiler strip 330. When the telescopic airbag 320 is inflated or deflated, it can drive the spoiler strip 330 to slide up and down along the telescopic sleeve 310, thereby realizing dynamic adjustment of the spoiler height. In actual application, the switching state of the electronic valve 230 can be adjusted as needed to control the inflation and deflation of each telescopic airbag 320, thereby realizing the lifting and lowering of the spoiler strip 330. The spoiler strips 330 of multiple lifting mechanisms 300 are arranged side by side, and the height of each spoiler strip 330 can be adjusted according to actual needs to achieve the best spoiler effect.

[0045] According to the spoiler device 1000 provided in the first embodiment of the present invention, when applied to a train, the compressor 210 and electronic valve 230 are combined to inflate or deflate the expandable airbag 320 as needed, thereby quickly adjusting the height of the spoiler strip 330 and achieving active control of air turbulence, effectively reducing air resistance and improving train energy efficiency. The compressor 210 and electronic valve 230 precisely control the expansion and contraction of the expandable airbag 320, thereby controlling the position of the spoiler strip 330. This optimizes airflow distribution around the train, reduces the impact of external factors such as crosswinds on train stability, and improves driving safety. Separate air intake ducts 220 and electronic valves 230 allow each spoiler strip 330 to be raised and lowered independently, enabling more refined control of airflow around the train. Different operating conditions or environments may require different spoiler configurations to optimize aerodynamic performance. Individually controlling each spoiler strip 330 ensures optimal airflow management in all circumstances. Furthermore, by precisely controlling the position of each spoiler strip 330, the train's aerodynamic efficiency can be further optimized, thereby reducing energy consumption. When additional spoiler effects are not required, some spoilers 330 can be lowered or completely retracted to reduce unnecessary air resistance.

[0046] It is understandable that when the spoiler strips 330 of the plurality of lifting mechanisms 300 rise simultaneously, the plurality of spoiler strips 330 can form a straight-line plate-like structure, thereby achieving air turbulence.

[0047] It is understandable that the size of the base 100, the number of lifting mechanisms 300, and the height of the spoiler strips 330 can be adjusted according to actual needs, and are not limited here.

[0048] Reference Figure 2 and Figure 3According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, the drive mechanism 200 also includes a main air pipe 240. The inner diameter of the main air pipe 240 is designed to be larger than the inner diameter of the intake pipe 220 to ensure smooth gas transmission within the main air pipe 240 and meet the air supply needs of multiple intake pipes 220. The compressor 210 is directly connected to the main air pipe 240 to deliver compressed air into the main air pipe 240. Each intake pipe 220 is connected to the main air pipe 240, ensuring that the air compressed by the compressor 210 is evenly distributed to each intake pipe 220 through the main air pipe 240. In a specific application, when the compressor 210 is operating, it compresses air and delivers it into the main air pipe 240. Because the inner diameter of the main air pipe 240 is larger than that of the intake pipe 220, it can accommodate more compressed air and serve as a buffer and distributor. The compressed air then enters the drive mechanism 200 within the spoiler through the various air inlet pipes 220, powering the spoiler's movement. This design not only ensures a stable and sufficient power source for the spoiler device 1000 but also evenly distributes the compressed air through the main air pipe 240, ensuring smooth and reliable spoiler operation. Furthermore, the presence of the main air pipe 240 facilitates maintenance and overhaul of the entire drive mechanism 200.

[0049] Reference Figure 2 and Figure 3 According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, fixing plates 211 are provided on both sides of the compressor 210, and the fixing plates 211 are firmly fixed to the bottom wall of the mounting cavity 110 by fasteners. Specifically, the fixing plates 211 are made of high-strength materials to ensure sufficient structural strength and rigidity, thereby effectively supporting and fixing the compressor 210. The fasteners pass through the fixing plates 211 and are tightly connected to the bottom wall of the mounting cavity 110, firmly mounting the compressor 210 within the mounting cavity 110 of the base 100. This design not only ensures the stability of the compressor 210 during operation and prevents it from shifting or being damaged due to vibration or external forces, but also improves the safety and reliability of the entire spoiler device 1000. In addition, this fixing method also facilitates the installation, disassembly, and maintenance operations of the compressor 210, improving the convenience of use of the device.

[0050] Reference Figure 2 and Figure 3According to the spoiler device 1000 provided by the first embodiment of the present invention, the base 100 includes a first mounting boss 170 located on the bottom wall of the mounting cavity 110 and specifically configured to secure each intake pipe 220. Specifically, the first mounting boss 170 is connected to the bottom wall of the mounting cavity 110 via fasteners, forming a stable support structure. Each intake pipe 220 is securely mounted to the first mounting boss 170 using a specific connection method, such as a mounting groove provided on the first boss and secured with fasteners or clamps. This design ensures the stability and sealing of the intake pipe 220, preventing gas leakage, while also optimizing the spatial layout, making the entire device more compact and efficient. This design not only improves the installation accuracy and stability of the intake pipe 220, but also greatly simplifies the installation and removal process, facilitating routine maintenance and inspection. Furthermore, the provision of the first mounting boss 170 enhances the structural strength of the entire spoiler device 1000, increasing its service life and reliability.

[0051] Reference Figure 2 and Figure 3 According to the spoiler device 1000 provided by the first embodiment of the present invention, mounting plates 171 are provided on either side of the first mounting boss 170. These plates 171 are securely fastened to the bottom wall of the mounting cavity 110 via fasteners, providing stability and support for the first mounting boss 170. Specifically, the mounting plates 171 and the first mounting boss 170 are integrally formed. Fasteners, such as bolts or screws, pass through the mounting plates 171 and screw into the bottom wall of the mounting cavity 110, thereby securely securing the mounting plates 171 in place. This design provides additional support and stability for the first mounting boss 170, helping to prevent displacement or damage caused by external forces or vibration. Furthermore, the presence of the mounting plates 171 increases the structural strength of the entire device, enhancing its resistance to external impacts. Furthermore, the design of the mounting plates 171 takes into account ease of use and maintainability. The selection and layout of the fasteners make installation and removal quick and easy, facilitating routine maintenance and inspection.

[0052] Reference Figure 2 and Figure 3According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, the base 100 includes a second mounting boss 180, the second mounting boss 180 is placed in the mounting cavity 110, and the lower end of each telescopic sleeve 310 is firmly fixed on the second mounting boss 180. This fixing method ensures the stability and reliability of the telescopic sleeve 310 during use, and it can maintain its predetermined position and posture whether in the telescopic process or in a static state. The second mounting boss 180 can be fixed above the first mounting boss 170 by means such as bolt connection, welding, etc. Such a layout not only ensures the compactness of the structure, but also realizes the effective connection between the air intake pipe 220 and the telescopic airbag 320 above.

[0053] Reference Figure 4 and Figure 5 According to the first embodiment of the present invention, a spoiler device 1000 is provided within the slot 120 at the upper end of the base 100. These partitions 130 are arranged at regular intervals, defining guide channels 140 between adjacent partitions 130. These guide channels 140 function to guide and secure the spoiler strip 330, ensuring that it can pass through the slot 120 stably and accurately. Each guide channel 140 has a guide bar 150 on its sidewall, which mates with a guide groove 331 on the sidewall of the spoiler strip 330. The sidewalls of the spoiler strip 330 are designed with guide grooves 331 extending from top to bottom. When the spoiler strip 330 passes through the guide channel 140, the guide bar 150 is inserted into these guide grooves 331. This design not only ensures that the spoiler strip 330 can smoothly pass through the slot 120 along a predetermined path, but also enhances the stability and accuracy of the spoiler strip 330 during the passage process. The matching design of guide strips 150 and guide slots 331 ensures effective guidance and support for spoiler strip 330 during movement, preventing potential deviation or shaking. In practice, when spoiler strip 330 needs to rise or fall, it moves along guide channel 140, while guide strips 150 provide guidance and positioning, ensuring that spoiler strip 330 accurately and quickly reaches the intended position. This design significantly enhances operational stability and reliability.

[0054] A train provided according to an embodiment of the second aspect of the present invention includes the spoiler device 1000 according to the embodiment of the first aspect of the present invention.

[0055] According to the train provided by the embodiment of the second aspect of the present invention, multiple spoiler devices 1000 are carefully placed at both ends of the car body 2000 in the train layout. This layout is designed to maximize the effectiveness of the spoiler devices 1000 to improve the train's stability and aerodynamic performance during high-speed travel. By installing the spoiler devices 1000 at both ends of the car body 2000, air resistance can be effectively reduced, improving the train's operating efficiency. In actual operation, when the train is traveling at high speed, the angle and position of the spoiler devices 1000 at both ends of the car body 2000 can be adjusted according to current external conditions to optimally guide airflow, reduce wind resistance, and enhance the train's handling stability.

[0056] Reference Figure 6 and Figure 12 According to the train provided by the embodiment of the second aspect of the present invention, a receiving groove is provided on the top of the car body 2000, and the spoiler device 1000 is arranged in the receiving groove. By installing the spoiler device 1000 in the receiving groove, the upper end of the base 100 is flush with the top of the car body 2000, which not only realizes the hidden installation of the device, but also improves the overall aesthetics and aerodynamic performance.

[0057] Furthermore, during installation, the base 100 of the spoiler device 1000 is securely positioned within the receiving slot, ensuring stability and reliability. Furthermore, the top of the base 100 remains flush with the top of the vehicle body 2000. This design not only enhances the train's appearance but also reduces wind resistance, improving operational efficiency.

[0058] Reference Figure 12 In practice, when the spoiler strip 330 is retracted, the spoiler assembly 1000 is completely concealed within the receiving slot, forming a smooth, integrated structure with the top of the vehicle body 2000, thereby reducing wind resistance during high-speed travel. When the spoiler strip 330 is deployed, it extends from the receiving slot, exerting its aerodynamic properties and enhancing the train's maneuverability and stability.

[0059] Reference Figure 2 and Figure 6 According to the train provided by the second embodiment of the present invention, an outer gear ring 160 is provided at the lower end of the base 100. A motor (not shown) and a gear 2100 are provided in a receiving groove. The outer gear ring 160 cooperates with the motor and gear 2100 in the receiving groove to form a sophisticated drive mechanism 200. The motor installed in the receiving groove rotates by driving the gear 2100, and the gear 2100 meshes with the outer gear ring 160, thereby driving the base 100 to rotate.

[0060] During use, the spoiler device 1000 has two modes: spoiler and auxiliary braking. When the motor is started, it can drive the gear 2100 to rotate. Since the gear 2100 is engaged with the outer gear ring 160, the rotation of the gear 2100 will drive the base 100 to rotate together. This design allows the spoiler device 1000 to flexibly adjust its angle as needed to adapt to different operating conditions and airflow conditions. For example, refer to Figures 7 to 9 When the spoiler device 1000 is in the spoiler mode, the spoiler strip 330 of the spoiler device 1000 forms an acute angle with the traveling direction of the train, thereby achieving a spoiler effect; Figure 10 and Figure 11 When the spoiler device 1000 is in the auxiliary braking mode, the spoiler strips 330 of the spoiler device 1000 are all raised and arranged side by side to form a plate-like structure. The plate-like structure formed by the spoiler strips 330 arranged side by side forms a right angle with the traveling direction of the train. During the running of the train, the airflow vertically hits the spoiler strips 330, thereby providing damping for the car body 2000.

[0061] It is understandable that, referring to Figures 7 to 9 When the spoiler device 1000 is in spoiler mode, the motor can be controlled to drive the base 100 to rotate according to information such as the vehicle model, speed, and external environment so that the spoiler strips 330 form an angle with the direction of the train. The heights of the spoiler strips 330 can also be adjusted so that the spoiler strips 330 form different shapes (such as triangles, trapezoids, rectangles, etc.), thereby better adapting to the driving state of the train and achieving the best aerodynamic effect.

[0062] Reference Figure 7 It can be understood that two spoiler devices 1000 can be set at both ends of the train. When the spoiler device 1000 is in the spoiler mode, the directions of the plate-like structures composed of the spoiler strips 330 of the two spoiler devices 1000 can be different, so as to achieve a better spoiler effect.

[0063] In some embodiments, the angle and position of the spoiler device 1000 can be precisely adjusted by controlling the forward and reverse rotation and speed of the motor to achieve optimal aerodynamic effect. This drive method is not only fast and precise, but can also meet the needs of the spoiler device 1000 under different train operating conditions.

[0064] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the spirit of the present invention.
