Description

Technical Field

[0001] The invention belongs to the technical field of riding simulation systems, relates to a technology for improving heat dissipation efficiency, and specifically relates to a heat dissipation structure and a riding simulation system. Background Art

[0002] Cycling simulators are devices used for indoor exercise and cycling training. By simulating a real cycling experience, users can get the same exercise effects as outdoor cycling in an indoor environment. Such systems are widely used in gyms, professional athlete training venues, and home fitness equipment. Cycling simulators can not only provide a stable training environment, but also adjust different resistance intensities to simulate various terrains and cycling conditions (such as flat roads, uphill and downhill) to meet the diverse cycling needs of users.

[0003] In modern cycling simulation systems, due to long-term high-intensity operation, key components such as the resistance device, control module, and drive motor inside the equipment will generate a lot of heat. If the heat dissipation is not timely or the heat dissipation efficiency is insufficient, the temperature inside the system will rise, which will affect the performance of the equipment and may even cause damage to the equipment. Therefore, the heat dissipation problem is an important factor affecting the stability and service life of the cycling simulation system.

[0004] Traditional heat dissipation methods usually use simple fans or natural ventilation structures, relying on ventilation holes on the device casing or auxiliary fans for heat dissipation. However, this heat dissipation method is inefficient, especially in high-intensity usage scenarios, and cannot meet the heat dissipation requirements inside the device. As users' requirements for cycling simulation systems gradually increase, the existing simple heat dissipation design can no longer meet the needs of efficient heat dissipation.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] See also Figures 1 to 9 As shown, the specific embodiments provided by the present invention are as follows:

[0056] like Figures 1 to 6 As shown, the first embodiment of the present invention provides a heat dissipation structure, including:

[0057] A first airflow guiding assembly 1 having a first air outlet end 101 and a first air inlet end 102;

[0058] A second airflow guiding assembly 2 having a second air outlet end 201 and a second air inlet end 202;

[0059] Wherein, the first airflow guiding assembly 1 is arranged inside the housing 301 of the resistance device 3 of the riding simulation system;

[0060] Furthermore, the first air inlet 102 is located inside the housing 301, and the axis L1 of the first air outlet 101 passes through at least the control module 302 and the drive motor 303 of the resistance device 3 along its airflow path;

[0061] Wherein, the second airflow guiding component 2 is arranged inside the seat tube 304 of the riding simulation system;

[0062] Furthermore, the second air inlet end 202 is located at a position where the inside of the seat tube 304 communicates with the inside of the shell 301 , and the second air outlet end 201 communicates with the outside of the shell 301 .

[0063] In this embodiment, the first air inlet 102 is located inside the housing 301, and air is introduced into the heat dissipation channel. The airflow passes through the control module 302 and the drive motor 303 of the resistance device 3 along the axis L1 of the first air outlet 101 to form a directional airflow path. Through this directional airflow structure, heat can be effectively taken away from the high-temperature area, thereby improving the heat dissipation efficiency. In particular, the control module 302 and the drive motor 303 are the most critical components in the system and the components where heat is generated most concentratedly. Therefore, the airflow is directly guided to these areas, and their temperature is effectively reduced through an efficient convection heat exchange mechanism to ensure the stable operation of the equipment.

[0064] The second airflow guiding assembly 2 also has a second air inlet end 202 and a second air outlet end 201, which are arranged inside the seat tube 304 of the riding simulation system. The second air inlet end 202 is located inside the seat tube 304 and communicates with the inside of the shell 301, while the second air outlet end 201 communicates with the outside of the shell 301. Different from the directional heat dissipation of the first airflow guiding assembly 1, the second airflow guiding assembly 2 focuses on forming a negative pressure area at its corresponding position through the exhaust effect. This negative pressure area draws air from the inside of the shell 301, prompting fresh air to evenly enter the inside of the shell 301 from the installation gap of the shell 301, thereby reducing the overall temperature of the system and ensuring the uniformity of the airflow in the system.

[0065] Typically, the cooling system needs to introduce external air through the air inlet channel, but this structure is prone to dust problems because dust in the air will enter the device with the airflow. Especially for precision motors and control modules 302, dust may cause system failure, poor heat dissipation and even performance degradation.

[0066] However, in this embodiment, the second airflow guiding assembly 2 does not adopt a traditional air inlet channel. Through the negative pressure area, the second airflow guiding assembly 2 causes fresh air from the outside to enter through the installation gap of the shell 301, rather than through a clear air inlet. This flow process is spontaneous and uniform, because the installation gaps are distributed throughout different parts of the shell 301, and there is no single centralized air inlet. The installation gaps are larger and more widely distributed than traditional air inlets, so the flow rate of air entering the shell 301 is lower. The ability of low-flow air to carry dust is significantly reduced, and most of the dust will not be able to enter the interior of the shell 301 due to gravity sedimentation. After the air introduced by the installation gap directly enters the shell 301, it will be guided by the first airflow guiding assembly 1 to form a directional cooling airflow, thereby avoiding the formation of turbulent areas in the shell 301 and further reducing the accumulation of dust.

[0067] Furthermore, since the air inlets are not concentrated in a specific area but are distributed at the installation gaps of the housing 301, the air forms a uniform path during the inflow process. The installation gaps are usually narrow, and dust with larger particles is not easy to enter through the gaps. Even if a small amount of dust enters with the airflow, it will be driven away from the high-temperature components by the difference in air flow rate in the subsequent airflow path. The continuous operation of the second airflow guide assembly 2 will generate continuous airflow, avoiding the long-term deposition of dust inside the housing 301, thereby achieving self-cleaning to a certain extent.

[0068] Thus, not only the direct entry of dust is avoided, but also the uniformity of air flow is ensured. Through this dust-free design, the air flows slowly and evenly, making it difficult for dust particles to enter the housing 301 through the flowing airflow, thereby reducing the risk of dust accumulation and ensuring the cleanliness of the system.

[0069] The design of the negative pressure area can also help the air form a continuous flow path within the entire heat dissipation structure, promoting the effective discharge of hot air inside the system. During the exhaust process, the hot air is quickly discharged, and the cold air enters from the installation gap to provide continuous cooling for the system. In this way, the temperature inside the housing 301 is evenly controlled, avoiding local overheating and ensuring the stability of the riding simulation system during long-term, high-load operation.

[0070] This embodiment forms an efficient heat dissipation system through the cooperation of two airflow guide components. The first airflow guide component 1 directly guides the airflow to the control module 302 and the drive motor 303 to form a directional cooling path to ensure that key components are fully cooled under high temperature conditions. The second airflow guide component 2 uses the negative pressure effect to exhaust hot air and guide cold air into the housing 301, further reducing the overall temperature of the system.

[0071] In summary, this embodiment improves the heat dissipation efficiency of the riding simulation system through dust-free design and dual heat dissipation mechanism, ensuring the stability and reliability of the system in a high-intensity usage environment.

[0072] In addition, the second air outlet end 201 of the second airflow guiding assembly 2 serves as a discharge channel for hot air, and a small amount of air flows back into the interior of the housing 301 .

[0073] Specifically, when the second airflow guiding assembly 2 discharges hot air to the outside, the high-speed flow of the airflow causes a local pressure drop, and such airflow forms a continuous exhaust channel, pushing the air out of the housing 301 through the second air outlet end 201 .

[0074] Since the air pressure of the external environment is higher than that of the inside of the shell 301, and the flow rate of the second air outlet 201 is relatively fast, part of the air will enter the second air outlet 201 during the exhaust process, especially when there is a difference between the negative pressure area inside the shell 301 and the external atmospheric pressure. Although the second air outlet 201 is mainly "outlet", under certain conditions, a small amount of air backflow will occur, that is, a small amount of air will enter the system from the outside through the air outlet. The phenomenon of air backflow produces a relatively weak but continuous air vibration effect. Specifically, the flow of air, especially from a low-pressure area to a high-pressure area, will produce a certain disturbance effect. Even if the amount of air backflow is small, this weak backflow will cause irregular disturbances in the airflow around the second air outlet 201, forming local airflow vibrations. This disturbance effect will cause the tiny dust particles in the shell 301 to be vibrated, so that it is not easy to accumulate in a certain position. Air vibration will cause a certain degree of turbulence in the airflow by changing the stability of the airflow. Turbulence can break the adhesion of dust particles on the surface, making it difficult for dust particles to deposit. Especially near high-temperature components, the turbulence effect can effectively disperse dust and prevent it from gathering. Even a weak air backflow will produce a pressure difference effect. When air enters the second air outlet 201 from the outside, the air flow speed is slow and the direction is unstable, which will cause slight vibrations inside the shell 301. Especially when the shell 301 material is relatively rigid, the micro-vibration of the air helps to reduce the deposition of dust on the surface of the component.

[0075] Since the second air outlet 201 will generate slight air backflow and airflow disturbance, dust is easy to settle in the stable airflow, and slight vibration and airflow disturbance will keep the dust particles in a state of constant movement, thereby reducing the adhesion of dust on the surface of the device.

[0076] Even a small amount of return air will enhance the fluidity of the air in the housing 301, so that the airflow is no longer discharged in a single direction, thereby avoiding dust accumulation caused by uneven airflow.

[0077] In addition, the second air outlet 201 faces and / or is connected to the heating module 6 (such as a dissipation resistor) of the riding simulation system to simultaneously dissipate heat from the heating module 6 and discharge the air that has completed heat exchange to the external environment of the shell 301.

[0078] In a specific embodiment, along the length direction of the housing 301, the center M1 of the first air inlet end 102 and the center M2 of the second air inlet end 202 satisfy:

[0079] The center M1 and the center M2 are located on both sides of the center line L3 of the shell 301 along the length direction and are arranged opposite to each other.

[0080] In this embodiment, the first airflow guiding assembly 1 effectively guides the air inside the housing 301, and its function is to guide the air inside the housing 301 to the heat source component and discharge it through the first air outlet 101. In this way, the first airflow guiding assembly 1 actually forms an airflow channel, and the air in the channel is mainly the air inside the housing 301, rather than the external air. This prevents the external air from directly entering the housing 301, and reduces the entry of dust.

[0081] Since the first airflow guide assembly 1 mainly utilizes the air inside the housing 301, there is no need to design an additional air inlet or external air channel, which effectively avoids the risk of external dust entering the housing 301 through the air inlet. In other words, it can be regarded as a closed air circulation system, in which the airflow mainly circulates inside the housing 301, effectively taking away and discharging the heat without introducing dust or impurities that may be carried from the outside.

[0082] In addition, the first airflow guiding assembly 1 forms a more direct convection heat exchange channel between the air flow path and the heat source. By guiding the air in the housing 301 and passing through the heat source, the first airflow guiding assembly 1 not only plays a role in heat dissipation, but also can maintain the overall temperature balance of the system.

[0083] In addition, as mentioned above, the second airflow guiding assembly 2 forms a negative pressure area inside the shell 301, so that fresh air from the outside can enter the shell 301 and exchange with the hot air inside the shell 301. The second air inlet end 202 (located on one side of the shell 301) ensures that the negative pressure area can be effectively formed and promotes the flow of air by guiding the outside air into the shell 301. The relative arrangement of the second air inlet end 202 and the first air inlet end 102 can ensure that the direction and distribution of air flow are uniform, and avoid the deviation of air flow inside the shell 301. In this way, it not only helps to effectively discharge hot air, but also the outside air can flow inside the entire shell 301, thereby taking away heat more evenly.

[0084] Through the first airflow guide assembly 1, the air is guided to the heat source (such as the control module 302, the drive motor 303, etc.) in the housing 301. Heat exchange is formed between these high-temperature components and the airflow, thereby improving the heat dissipation efficiency. The arrangement of the first air inlet end 102 and the relative arrangement of the second air inlet end 202 work together to form an effective airflow circulation system, ensuring that the heat source area can be effectively cooled.

[0085] In a specific embodiment, the first airflow guide component 1 is a fan, and the second airflow guide component 2 is a fan. The high-speed airflow of the fan not only enhances the cooling of the control module 302 and the drive motor 303, but also speeds up the flow of air inside the housing 301 and the discharge of heat, providing a strong and stable heat dissipation guarantee for the riding simulation system.

[0086] In a specific embodiment, the control module 302 refers to a component including a circuit board and other related electrical components. As the core control unit of the riding simulation system, the control module 302 is responsible for data processing, system control, parameter adjustment and other functions. Since the control module 302 generates a lot of heat during the operation of the system, an effective heat dissipation design is required to ensure its stable operation.

[0087] The circuit boards, processors, sensors and other electrical components in the control module 302 are all sensitive to temperature, and excessively high temperatures may affect their working stability or shorten their service life. In the heat dissipation structure of the present invention, the directional airflow of the first airflow guiding component 1 can directly guide the cold air to the location of the control module 302, thereby achieving effective heat dissipation of the circuit boards and electrical components, and ensuring that they maintain a stable working state under high-intensity operating conditions.

[0088] In a specific embodiment, when the rotor of the driving motor 303 rotates, it drives the surrounding air to move together, thereby forming an airflow inside the housing 301. The airflow helps to strengthen the air flow inside the housing 301 and provide auxiliary cooling effect for the heat dissipation structure.

[0089] When the rotor of the driving motor 303 rotates at high speed, the surrounding air also circulates, causing the air to flow to the control module 302 and other high-heat areas, and the first airflow guide component 1 will also guide the airflow to this area, and the flow directions of the two parts of the airflow tend to be opposite, thereby forming convection heat exchange. In general, the airflow effect of the rotor is combined with the airflow of the first airflow guide component 1 and the second airflow guide component 2 to form a multi-level airflow network, which can more efficiently discharge heat from the outside of the housing 301, significantly improving the overall heat dissipation effect of the riding simulation system.

[0090] In a specific embodiment, the reason for arranging the second airflow guide in the seat tube 304 is that it will not affect the overall appearance and size of the system, and at the same time, the internal space is used to the maximum extent, the efficiency of airflow guidance is improved, and the heat dissipation performance of the system is further enhanced. In addition, arranging the second airflow guide assembly 2 here can avoid interference with other internal structures, making the airflow path smoother. In addition, the seat tube 304 is usually directly connected to the shell 301. Through this arrangement, it is convenient to achieve air communication between the inside and the outside, discharge the hot air in the shell 301 to the external environment, form a stable air circulation, and help reduce the temperature inside the shell 301.

[0091] like Figures 5 to 8 As shown, the second embodiment of the present invention proposes a heat dissipation structure, and on the basis of the first embodiment, includes a flow guide component 4;

[0092] The flow guide component 4 is arranged at the port position of the first air outlet end 101;

[0093] The area of ​​the orthographic projection of the air guide component 4 at the first air outlet end 101 is S1, and the port area of ​​the first air outlet end 101 is S2;

[0094] It satisfies that S1=K1*S2, and the value range of K1 is 0.3 to 0.6.

[0095] In this embodiment, the airflow guidance and heat dissipation effects are further optimized by adding a guide component 4 at the port position of the first air outlet 101. The guide component 4 is arranged at the port position of the first air outlet 101, and can guide the airflow at the air outlet for a second time, so that the airflow direction is more concentrated and the cooling effect is enhanced.

[0096] Specifically, the ratio K1 between the orthographic projection area S1 of the air guide component 4 and the port area S2 of the first air outlet 101 is between 0.3 and 0.6, and this ratio range can ensure that the air guide component 4 appropriately shrinks the flow area of ​​the airflow, thereby forming a stronger airflow concentration effect at the first air outlet 101. This design helps to increase the airflow speed, so that when the air flows through key components such as the control module 302 and the drive motor 303, it can more efficiently take away heat, thereby improving the convective heat exchange efficiency of these high-temperature areas.

[0097] like Figure 5 As shown, the third embodiment of the present invention proposes a heat dissipation structure, and based on the previous embodiment, the guide component 4 has:

[0098] A first guide end 401 and a second guide end 402;

[0099] Wherein, the first guide end 401 is located at the port position of the first air outlet end 101;

[0100] The second guide end 402 is located at one side of the driving motor 303 of the resistance device 3 .

[0101] In this embodiment, by designing the first guide end 401 and the second guide end 402 on the air guide component 4, the airflow guide path is further optimized, making the heat dissipation effect more concentrated and efficient.

[0102] Specifically, the first guide end 401 is located at the port position of the first air outlet 101. This design ensures that the airflow can directly enter the guide path of the guide component 4 when it flows out from the first air outlet 101, avoiding airflow diffusion and effectively enhancing the concentration of the airflow.

[0103] The second guide end 402 extends to one side of the drive motor 303 of the resistance device 3. This design directs the airflow to the high temperature area of ​​the drive motor 303, so that the airflow can fully conduct convection heat exchange when flowing through the surface of the drive motor 303, and quickly take away the heat generated by the drive motor 303.

[0104] In this embodiment, the first guide end 401 and the second guide end 402 of the air guide component 4 cooperate to form a directional cooling channel near the drive motor 303, further enhancing the heat dissipation effect of the drive motor 303. In this way, not only the cooling efficiency of the drive motor 303 area is improved, but also the accumulation of heat near the drive motor 303 is effectively prevented, thereby improving the heat dissipation stability and overall durability of the system under high-intensity operation. This structural design further enhances the effect of airflow guidance and provides a more reliable heat dissipation solution for the riding simulation system.

[0105] like Figure 5 As shown, the fourth embodiment of the present invention proposes a heat dissipation structure, and based on the previous embodiment, the guide component 4 has:

[0106] A first end surface 403 and a second end surface 404;

[0107] Wherein, the first end surface 403 is provided with a plurality of flow guiding channels 4031;

[0108] The second end surface 404 is a plane and faces the control module 302 .

[0109] In this embodiment, the air guide component 4 realizes the airflow diversion function, and through precise structural optimization, the airflow can effectively and directionally cool the drive motor 303 and the control module 302, thereby achieving a multi-level heat dissipation effect.

[0110] Specifically, after the airflow enters the air guide assembly 4, the air guide channel 4031 of the first end surface 403 guides a portion of the airflow to the area of ​​the drive motor 303. There are multiple air guide channels 4031, which are arranged linearly, so that the airflow has the characteristics of being concentrated and high-speed after passing through the channels, and can be blown directionally to the surface of the drive motor 303. This part of the airflow forms a strong local convection around the drive motor 303, quickly taking away the heat on the surface of the motor, thereby ensuring that the drive motor 303 will not be degraded in performance or malfunction due to overheating during long-term high-load operation.

[0111] The other part of the airflow is guided through the second end surface 404 of the air guide component 4. The second end surface 404 is designed to be flat, opposite to the surface of the control module 302 and facing the circuit board and sensitive electrical components in the control module 302. Since the airflow is not centrally guided by the channel when flowing at the second end surface 404, it can blow evenly on the surface of the control module 302 in the form of a lower speed and a larger coverage area. This low-speed and widely distributed airflow characteristic is particularly suitable for electronic components with relatively mild heat dissipation requirements and large surface areas, and can form a uniform cooling layer on the control module 302 to avoid local overheating.

[0112] The airflow is divided into two parts by the flow guide component 4 and guided to the drive motor 303 and the control module 302, which not only realizes the effective distribution of the airflow, but also achieves the synergistic effect of overall heat dissipation and local heat dissipation through the combination of directional and uniform cooling. The high-speed, concentrated airflow forms strong cooling at the drive motor 303, while the low-speed, uniform airflow forms gentle heat dissipation on the surface of the control module 302. The two cooperate with each other and significantly improve the efficiency of the entire heat dissipation system.

[0113] The design of the flow guide component 4 also allows the airflow division ratio to be controlled by adjusting the number, width or angle of the flow guide channels 4031 of the first end surface 403. For example, when the load of the drive motor 303 is high, the flow guide channels 4031 of the first end surface 403 can be added or expanded to increase the airflow flow to the drive motor 303; and when the heat dissipation requirement of the control module 302 is higher, the ventilation area of ​​the channel of the first end surface 403 can be appropriately reduced, thereby increasing the flow of the airflow at the second end surface 404 to meet the cooling requirements under different working conditions.

[0114] In summary, the air guide component 4 of this embodiment uses a refined air flow segmentation and guidance design to enable the heat dissipation air flow to be reasonably distributed between the drive motor 303 and the control module 302, which not only ensures the local cooling of the drive motor 303, but also provides a gentle and uniform cooling effect for the control module 302. This optimized design can not only effectively control the core temperature of the device and improve the stability of the system, but also provide flexibility to cope with the heat dissipation requirements under different usage loads, ensuring that the riding simulation system can operate safely and reliably under various working conditions.

[0115] The fifth embodiment of the present invention proposes a heat dissipation structure, and based on the previous embodiment, the seat tube 304 has an air intake port 3041 located inside the housing 301 of the resistance device 3;

[0116] Wherein, the second airflow guiding component 2 is located inside the air inlet port 3041;

[0117] The second air outlet 201 passes through the interior of the housing 301 and is in communication with the exterior of the housing 301;

[0118] An air intake gap is formed between the second air outlet end 201 and the air intake port 3041 .

[0119] In this embodiment, the main function of the air inlet port 3041 of the seat tube 304 is to ensure that the seat tube 304 is connected to the inside of the shell 301, and to provide an airflow path for the second airflow guiding assembly 2 so as to more effectively extract and discharge the hot air inside the shell 301 to the external environment.

[0120] Specifically, the air inlet port 3041 of the seat tube 304 is arranged inside the housing 301 of the resistance device 3, so as to ensure that the air inside the housing 301 can be connected to the second airflow guide assembly 2 through the seat tube 304. That is, an air extraction channel is provided for the second airflow guide assembly 2, so that the hot air can be smoothly extracted from the housing 301.

[0121] The second airflow guide assembly 2 is located inside the air inlet port 3041, and its second air outlet end 201 passes through the housing 301 and is connected to the outside. In this way, through the air inlet port 3041, the second airflow guide assembly 2 can directly extract hot air from the inside of the housing 301 and discharge it to the outside of the housing 301, effectively reducing the internal temperature.

[0122] Due to the presence of the air inlet port 3041, the second airflow guide assembly 2 can complete the air extraction process more efficiently, ensuring that the air inside the housing 301 will not be stagnant or form temperature accumulation, thereby improving the overall heat dissipation effect of the system. The air inlet gap between the air inlet port 3041 and the second air outlet 201 further ensures the smooth flow of air. Through the gap, air flows from the inside of the housing 301 to the outside, forming a stable exhaust path to prevent airflow from being blocked or backflowing.

[0123] In summary, this embodiment realizes the communication between the inside of the housing 301 and the external environment through the air inlet port 3041 of the seat tube 304, ensuring that the second airflow guide assembly 2 can smoothly extract the hot air inside the housing 301 and discharge it. This design not only ensures the temperature control inside the system, but also provides more reliable heat dissipation support for the long-term stable operation of the riding simulation system.

[0124] In a specific embodiment, the second air outlet end 201 is designed as an independent air outlet channel to further optimize the exhaust effect and enhance the heat dissipation efficiency. The independent air outlet channel design helps to ensure that the hot air inside the housing 301 can be discharged to the external environment more directly and smoothly.

[0125] Specifically, by designing the second air outlet end 201 as an independent air outlet channel, the interference and resistance of the airflow during the discharge process can be reduced, ensuring the smoothness of the airflow path. This design helps to achieve directional discharge of air, so that the hot air inside the housing 301 can be quickly discharged to avoid heat accumulation inside.

[0126] The independent air outlet channel avoids cross interference between the airflow and other parts of the housing 301, making the exhaust path single and efficient. The airflow can be directly discharged to the external environment along the independent channel, forming a fast and effective air exchange process. This design can accelerate the reduction of the internal temperature of the housing 301 and help maintain the heat dissipation balance of the system.

[0127] Moreover, the independent air outlet channel effectively prevents the airflow inside and outside the housing 301 from interfering with each other, and reduces the possibility of airflow backflow and turbulence. The airflow will not be affected by other components when flowing from the inside of the housing 301 to the outside, thereby ensuring the directionality and stability of the airflow, which is crucial for maintaining cooling efficiency.

[0128] like Fig. 9 As shown, the sixth embodiment of the present invention proposes a heat dissipation structure, and based on the previous embodiment, the axial flow area S3 of the first airflow guiding component 1 and the axial flow area S4 of the second airflow guiding component 2 satisfy:

[0129] S4=K2*S3, the value range of K2 is 1 to 1.5.

[0130] In this embodiment, by optimizing the axial flow area ratio of the first airflow guiding assembly 1 and the second airflow guiding assembly 2, the flow of the airflow inside the housing 301 is made more balanced, further improving the heat dissipation effect of the system.

[0131] Specifically, this embodiment provides that the axial flow area S3 of the first airflow guiding assembly 1 and the axial flow area S4 of the second airflow guiding assembly 2 satisfy a proportional relationship. The design of this proportional relationship ensures that the axial flow area of ​​the second airflow guiding assembly 2 is larger than the first airflow guiding assembly 1, providing a larger air exhaust channel, which helps to quickly exhaust the hot air inside the housing 301.

[0132] Since the first airflow guide assembly 1 is located inside the housing 301, its main function is to increase the flow velocity of the airflow inside the housing 301. By setting an appropriate axial flow area, the first airflow guide assembly 1 can enhance the fluidity of the internal air, so that the hot air flows quickly in the high temperature area inside the housing 301 (such as around the drive motor 303 and the control module 302). This accelerated flow helps to improve the efficiency of convective heat exchange and quickly move the hot air to the exhaust path.

[0133] Since the function of the second airflow guide assembly 2 is to extract and discharge the hot air in the housing 301, its larger axial flow area makes the exhaust effect stronger, which is conducive to forming a stable exhaust channel and ensuring that the hot air can be discharged efficiently. By increasing the axial flow area of ​​the second airflow guide assembly 2, the system can form a low-pressure area while discharging the hot air, promoting the first airflow guide assembly 1 to accelerate the internal airflow circulation.

[0134] Since the first airflow guide assembly 1 and the second airflow guide assembly 2 form a good match in terms of area and function, the airflow accelerated by the first airflow guide assembly 1 forms convection inside the housing 301, quickly driving the hot air to flow to the exhaust channel where the second airflow guide assembly 2 is located, and the exhaust function of the second airflow guide assembly 2 allows the hot air to be quickly discharged. Through this dual effect, the temperature inside the housing 301 can be quickly reduced to maintain the internal temperature balance.

[0135] The set axial flow area ratio is not only suitable for normal operating conditions, but also can meet the heat dissipation requirements under high load conditions. Under high load, the larger axial flow area of ​​the second airflow guide component 2 can effectively enhance the heat dissipation capacity, while the airflow acceleration function of the first airflow guide component 1 ensures the efficiency of the internal air flow. This design can adapt to the heat dissipation requirements under various working conditions and ensure that the system can operate efficiently for a long time.

[0136] In summary, this embodiment optimizes the axial flow area ratio of the first and second airflow guide assemblies 2 to enhance the flow rate and exhaust efficiency of the airflow, so that the hot air in the housing 301 can be quickly removed, achieving a more efficient heat dissipation effect. This design provides a reliable heat dissipation guarantee for the riding simulation system under high load and long-term working conditions, prolongs the service life of the system, and ensures its stability.

[0137] like Figure 6 As shown, the seventh embodiment of the present invention proposes a heat dissipation structure, and based on the previous embodiment, the axis L2 of the second air outlet end 201 and the center line L3 of the shell 301 along the length direction have a set angle a, and the value range of the angle a is 30° to 90°.

[0138] In this embodiment, by setting the angle a, the exhaust path of hot air is further optimized, which helps to improve the overall heat dissipation efficiency.

[0139] Specifically, the angle a ranges from 30° to 90°, and such an angle helps ensure that the exhausted hot air can leave the housing 301 along the best path, avoiding direct backflow to the surface of the housing 301, thereby reducing the temperature accumulation caused by the backflow of airflow. Specifically, when the hot air is discharged from the second air outlet 201 at the set angle a, the airflow will continue to move along the angle and follow the inertial path away from the housing 301. When the angle is set at 30° to 90°, the airflow has a directionality of diffusing outward, which enhances the tendency of the hot air to move away from the housing 301 and helps to quickly discharge heat.

[0140] Based on this, when the axis of the second air outlet 201 is at an appropriate angle to the axis of the housing 301, the airflow is more easily discharged smoothly and away from the outer surface of the housing 301, avoiding the stagnation and backflow phenomenon that may be caused by the exhaust design. The angle range of 30° to 90° can ensure that the exhaust will not directly approach the outer wall of the housing 301, but diffuse to a farther area, thereby improving the exhaust efficiency.

[0141] In summary, this embodiment sets the angle a between the axis L2 of the second air outlet 201 and the lengthwise midline L3 of the housing 301, making the exhaust path more directional and efficient, preventing hot air from flowing back, and optimizing the overall heat dissipation effect. This design improves the heat dissipation performance of the riding simulation system under high load and long-term use, and further ensures the stability and operating life of the system.

[0142] The eighth embodiment of the present invention proposes a heat dissipation structure, and based on the previous embodiment, the flow guide component 4 has:

[0143] The diversion grooves 405 are arranged on two side wall surfaces of the flow guide component 4 .

[0144] In this embodiment, the diverter groove 405 is located on the two side walls of the flow guide component 4. By setting two parallel groove structures, the incoming airflow can be diverted. The diverted airflow flows along the groove, forming a more uniform distribution inside the flow guide component 4, avoiding the concentration and turbulence of the airflow. The diverter groove 405 can also guide the airflow to the designated cooling area, ensuring that the airflow achieves efficient convection heat exchange when flowing through the heat source (such as the control module 302 and the drive motor 303), further improving the cooling effect.

[0145] The ninth embodiment of the present invention proposes a heat dissipation structure, and on the basis of the previous embodiment, comprises an air outlet cover 5, which is arranged at the port position of the second air outlet 201;

[0146] The air outlet cover 5 has a plurality of air outlet holes.

[0147] In this embodiment, the air outlet cover 5 is arranged at the port of the second air outlet 201, which can rectify and disperse the exhaust airflow, so that the exhaust hot air flow is more stable. At the same time, the existence of the air outlet cover 5 can prevent external dust or debris from entering the system, protecting the cleanliness of the internal structure and the operational stability.

[0148] The air outlet cover 5 can also provide a separation barrier for the airflow, effectively control the exhaust direction, prevent the airflow from directly flowing back to the surface of the shell 301, reduce airflow turbulence, and improve the overall exhaust efficiency.

[0149] The outlet cover 5 is designed with multiple outlet holes, which can evenly distribute and direct the airflow. The multi-hole design can form a uniform airflow distribution at the outlet end by dividing the airflow into multiple small streams, reducing the uneven flow rate and turbulence caused by a single exhaust hole.

[0150] The number, diameter and distribution of air outlets can be optimized according to the heat dissipation requirements to achieve the best exhaust effect. Smaller apertures can slow down the air flow speed and improve the stability of exhaust, while larger apertures can appropriately increase the exhaust volume and enhance the heat dissipation effect.
