[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. 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.

[0023] 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, its working principle is similar to that of ailerons on an airplane or the tail wing on a car. It reduces 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 vehicles slow down by increasing the frontal area and increasing air resistance. However, with the development trend of diversified shapes 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, it has become an inevitable trend to develop spoiler devices that can be dynamically adjusted according to the operating status.

[0024] To solve this problem, a first embodiment of the present invention provides a spoiler device 1000 for use in trains. The specific structure and function of the spoiler device 1000 provided by the embodiment of the present invention will be further described below in conjunction with text and drawings.

[0025] Reference Figures 1 to 5According to the first aspect of the present invention, a spoiler device 1000 is provided, comprising: a base 100 and a lifting assembly, wherein the base 100 is provided with an installation cavity 110 for installing the lifting assembly. A slot 120 is provided at the top of the base 100, and the slot 120 is connected to the installation cavity 110, so as to facilitate the lifting and lowering of the spoiler strip 330. The lifting assembly is composed of a driving mechanism 200 and a plurality of lifting mechanisms 300. The driving mechanism 200 comprises an air compressor 210, a plurality of air inlet pipes 220 and a plurality of electronic valves 230. The air compressor 210 is respectively connected to the plurality of air inlet pipes 220 to provide an air source for the telescopic airbag 320. An electronic valve 230 is provided on each air inlet pipe 220, and the opening and closing of the air inlet pipe 220 can be realized by controlling the switch of the electronic valve 230, so as to control the inflation and deflation of the telescopic airbag 320. The lifting mechanism 300 comprises a telescopic sleeve 310, a telescopic airbag 320 and a spoiler strip 330. The telescopic sleeve 310 is fixed on the base 100 to provide guidance 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 penetrated by the slot 120. The telescopic airbag 320 is arranged in the spoiler strip 330. When the telescopic airbag 320 is inflated or deflated, the spoiler strip 330 can be driven to slide up and down along the telescopic sleeve 310, thereby realizing the dynamic adjustment of the spoiler height. In practical applications, 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 the multiple lifting mechanisms 300 are arranged in parallel, and the height of each spoiler strip 330 can be adjusted according to actual needs to achieve the best spoiler effect.

[0026] According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, the spoiler device 1000 is applied to the train. Through the combination of the air compressor 210 and the electronic valve 230, the telescopic airbag 320 can be inflated or exhausted as needed, so as to quickly adjust the height of the spoiler strip 330, realize active control of air spoiler, effectively reduce air resistance, and improve train energy efficiency; through the air compressor 210 and the electronic valve 230, the telescopic airbag 320 can be accurately controlled to control the position of the spoiler strip 330, which can optimize the airflow distribution around the train, reduce the influence of external factors such as side wind on the stability of the train, and improve driving safety. Through the separate air intake pipe 220 and the electronic valve 230, each spoiler strip 330 can be raised and lowered separately, so as to realize more refined control of the airflow around the train. Under different operating conditions or environments, different spoiler configurations may be required to optimize aerodynamic performance. Individually controlling each spoiler strip 330 can ensure that the best airflow management effect can be obtained under any circumstances. In addition, by precisely controlling the position of each spoiler strip 330, the aerodynamic efficiency of the train can be further optimized, thereby reducing energy consumption. When no additional spoiler effect is needed, some spoiler strips 330 can be lowered or completely retracted to reduce unnecessary air resistance.

[0027] It can be understood 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.

[0028] 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 the size of the base 100, the number of lifting mechanisms 300, and the height of the spoiler strips 330 are not limited here.

[0029] Reference Figure 2 and Figure 3According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, the driving mechanism 200 also includes a main air pipe 240, and the inner diameter of the main air pipe 240 is designed to be larger than the inner diameter of the intake pipe 220, so as to ensure the smooth transmission of gas in the main air pipe 240 and meet the air supply requirements of multiple intake pipes 220. The compressor 210 is directly connected to the main air pipe 240 to send compressed air into the main air pipe 240. Each intake pipe 220 is connected to the main air pipe 240, so as to ensure that the air compressed from the compressor 210 can be evenly distributed to each intake pipe 220 through the main air pipe 240. In a specific application, when the compressor 210 is working, it will compress the air and send it into the main air pipe 240. Since the inner diameter of the main air pipe 240 is larger than the intake pipe 220, it can accommodate more compressed air and play a role of buffering and distribution. Subsequently, the compressed air enters the driving mechanism 200 inside the spoiler through each air inlet pipe 220, providing power for the action of the spoiler. This design can not only ensure that the spoiler device 1000 obtains a stable and sufficient power source, but also can achieve uniform distribution of compressed air through the main air pipe 240, thereby ensuring the smooth and reliable action of the spoiler. In addition, due to the existence of the main air pipe 240, it is also convenient to maintain and repair the entire driving mechanism 200.

[0030] 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 arranged on both sides of the compressor 210, and the fixing plates 211 are firmly fixed on the bottom wall of the installation cavity 110 by fasteners. Specifically, the fixing plates 211 are made of high-strength materials to ensure that they have sufficient structural strength and rigidity, so that the compressor 210 can be effectively supported and fixed. The fasteners pass through the fixing plates 211 and are tightly connected to the bottom wall of the installation cavity 110, so that the compressor 210 is firmly installed in the installation cavity 110 of the base 100. Through this design, not only the stability of the compressor 210 during operation is guaranteed, and it is prevented from being displaced or damaged due to vibration or external force, but also the safety and reliability of the entire spoiler device 1000 are improved. In addition, this fixing method also facilitates the installation, disassembly and maintenance operations of the compressor 210, and improves the convenience of use of the device.

[0031] 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 first mounting boss 170, which is located on the bottom wall of the mounting cavity 110 and is specifically used to fix each intake pipe 220. Specifically, the first mounting boss 170 is connected to the bottom wall of the mounting cavity 110 by a fastener to form a stable support structure. Each intake pipe 220 is firmly mounted on the first mounting boss 170 by a specific connection method, such as setting a mounting groove on the first boss and fixing it with a fastener, fixing it with a clamp, etc. Such a design ensures the stability and sealing of the intake pipe 220, prevents gas leakage, and also optimizes the spatial layout, making the entire device more compact and efficient. Through this design, not only the installation accuracy and stability of the intake pipe 220 are improved, but also the installation and disassembly process is greatly simplified, which is convenient for daily maintenance and overhaul. In addition, the setting of the first mounting boss 170 also enhances the structural strength of the entire spoiler device 1000, and improves its service life and reliability.

[0032] Reference Figure 2 and Figure 3 According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, mounting plates 171 are provided on both sides of the first mounting boss 170, and the mounting plates 171 are firmly fixed to the bottom wall of the mounting cavity 110 by fasteners, providing stability and support for the first mounting boss 170. Specifically, the mounting plate 171 and the first mounting boss 170 are an integrally formed structure; fasteners, such as bolts or screws, can pass through the mounting plate 171 and screw into the bottom wall of the mounting cavity 110, thereby firmly fixing the mounting plate 171 at a predetermined position. Through this design, the first mounting boss 170 is provided with additional support and stability, which helps to prevent displacement or damage caused by external force or vibration. At the same time, the presence of the mounting plate 171 also increases the structural strength of the entire device and improves its ability to resist external impact. In addition, the design of the mounting plate 171 also takes into account ease of use and maintainability. The selection and layout of the fasteners make the installation and removal process simple and quick, and facilitate daily maintenance and repair.

[0033] 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 arranged 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.

[0034] Reference Figure 4 and Figure 5 According to the spoiler device 1000 provided by the embodiment of the first aspect of the present invention, a plurality of partitions 130 are arranged in the slot 120 at the upper end of the base 100, and these partitions 130 are arranged at a certain interval, so that a guide channel 140 is defined between adjacent partitions 130. The function of these guide channels 140 is to guide and fix the spoiler strip 330 to ensure that it can stably and accurately pass through the slot 120. A guide strip 150 is provided on the side wall of each guide channel 140, and these guide strips 150 match the guide groove 331 on the side wall of the spoiler strip 330. The side wall of the spoiler strip 330 is designed with a guide groove 331 extending from top to bottom, and when the spoiler strip 330 passes through the guide channel 140, the guide strip 150 will be 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 passing process. The matching design of the guide bar 150 and the guide groove 331 enables the spoiler bar 330 to be effectively guided and supported during the movement, avoiding possible deviation or shaking. In practical applications, when the spoiler bar 330 needs to rise or fall, the spoiler bar 330 will move along the guide channel 140, and the guide bar 150 plays a role in guiding and positioning, ensuring that the spoiler bar 330 can accurately and quickly reach the predetermined position. This design greatly enhances its working stability and reliability.

[0035] A train provided according to an embodiment of the second aspect of the present invention comprises a spoiler device 1000 according to an embodiment of the first aspect of the present invention.

[0036] According to the train provided by the embodiment of the second aspect of the present invention, in the layout of the train, a plurality of spoiler devices 1000 are carefully placed at both ends of the length direction of the car body 2000. This layout is intended to maximize the role of the spoiler device 1000 to improve the stability and aerodynamic performance of the train when running at high speed. By installing the spoiler device 1000 at both ends of the car body 2000, the air resistance can be effectively reduced and the operation efficiency of the train can be improved. In actual operation, when the train is running at high speed, the spoiler device 1000 at both ends of the car body 2000 can be adjusted in angle and position according to the current external conditions to guide the airflow in the best way, reduce wind resistance, and improve the control stability of the train.

[0037] Reference Figure 6 and Fig.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.

[0038] In addition, during the installation process, the base 100 of the spoiler device 1000 is firmly placed in the receiving groove to ensure its stability and reliability. At the same time, the upper end of the base 100 is kept flush with the top of the car body 2000. This design not only optimizes the appearance of the train, but also reduces wind resistance and improves the running efficiency of the train.

[0039] Reference Fig.12 In actual application, when the spoiler strip 330 is in a retracted state, the spoiler device 1000 can be completely hidden in the receiving groove, forming a smooth whole with the top of the car body 2000, thereby reducing the wind resistance of the train when running at high speed. When the spoiler needs to be deployed, the spoiler strip 330 will extend from the receiving groove to exert its aerodynamic effect and improve the controllability and stability of the train.

[0040] Reference Figure 2 and Figure 6 According to the train provided by the embodiment of the second aspect of the present invention, an outer gear ring 160 is provided at the lower end of the base 100, a motor (not shown in the figure) and a gear 2100 are provided in the accommodating cavity, and the outer gear ring 160 cooperates with the motor and the gear 2100 in the accommodating cavity to form a sophisticated driving mechanism 200. The motor installed in the accommodating cavity rotates by driving the gear 2100, and the gear 2100 meshes with the outer gear ring 160, thereby driving the base 100 to rotate.

[0041] 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 meshed 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, referring 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; Fig.10 and Fig.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.

[0042] 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 so that the spoiler strip 330 forms an angle with the direction of the train according to information such as the vehicle model, speed, and external environment. The heights of different spoiler strips 330 can also be adjusted so that different spoiler strips 330 form different shapes (such as triangles, trapezoids, rectangles, etc.), so as to better adapt to the driving state of the train and achieve the best aerodynamic effect.

[0043] 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.

[0044] 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, thereby achieving the best aerodynamic effect. This driving method is not only fast but also accurate, and can meet the needs of the train for the spoiler device 1000 under different operating conditions.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
