Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a heat dissipation protection structure based on UAV motors. Background Technology

[0002] As the core power source of drones, the performance of the drone motor directly determines the drone's flight efficiency, payload capacity, and endurance. As a key device for converting electrical energy into mechanical energy, it supports the widespread application of drones in fields such as aerial photography and mapping, logistics and transportation, agricultural plant protection, and emergency rescue.

[0003] In existing technologies, traditional drone motor cooling solutions utilize a fixed design for the cooling fan as the core heat dissipation component. While this design can maintain basic heat dissipation under certain conditions, with the diversification of drone applications and the continuous improvement of motor performance, the fixed cooling fan's blade installation angle and airflow guidance device are both rigid structures with no adjustment. This unidirectional forced convection mode can remove the heat generated by the motor through continuous airflow displacement when the drone is in stable flight. However, when the drone performs complex maneuvers or is in a variable natural environment, the fixed-direction cooling airflow cannot effectively cover all the core heat-generating areas of the motor, resulting in localized heat accumulation. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation protection structure based on a drone motor, in order to solve the problem that the traditional drone motor heat dissipation scheme proposed in the background art uses a fixed cooling fan as the core component, and its fan blade installation angle and airflow guiding device are non-adjustable rigid structures, which can only achieve forced convection heat dissipation in one direction, resulting in heat accumulation in some areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation protection structure based on a drone motor, including a drone body, a main support assembly mounted on the drone body, a mounting shell mounted on the main support assembly, support legs fixedly mounted on the mounting shell, a filter assembly and an inner support assembly mounted on the mounting shell, an inner motor body and a main drive assembly mounted inside the mounting shell, a spiral blade body mounted on the drive assembly, a transmission assembly mounted on the mounting shell, and a rotation drive assembly and a cooling fan mounted on the inner support assembly, wherein the transmission assembly is connected between the main drive assembly and the rotation drive assembly; The internal motor body drives the spiral blade body to rotate through the main drive assembly. When the main drive assembly is working, it drives the rotation drive assembly to work through the transmission assembly. When the rotation drive assembly is working, it rotates through the internal support assembly and the cooling fan.

[0006] According to the preferred embodiment of this technical solution, the main support assembly includes a fixed support that is fixedly installed on the main body of the drone and a folding support that is rotatably connected to the fixed support, and the mounting shell is fixedly installed on the folding support.

[0007] In a preferred embodiment of this technical solution, the main drive assembly includes a first gear fixedly connected to the output end of the inner motor body and a second gear meshing with the first gear. The second gear is rotatably connected to the mounting housing. The spiral blade body is fixedly mounted on the second gear. The inner motor body is used to drive the first gear to rotate. When the first gear rotates, it drives the spiral blade body to rotate through meshing with the second gear.

[0008] In a preferred embodiment of this technical solution, the rotation drive assembly includes a first rotating seat rotatably connected to the mounting bracket and a connecting round rod fixedly connected to the first rotating seat. A transmission assembly is connected between the second gear and the first rotating seat. When the second gear rotates, the first rotating seat is driven to rotate through the transmission assembly.

[0009] In a preferred embodiment of this technical solution, the transmission assembly includes a third gear fixedly mounted on the second gear, a fourth gear meshing with the third gear, a first bevel gear fixedly connected to the fourth gear, a second bevel gear meshing with the first bevel gear, a first transmission wheel fixedly connected to the second bevel gear, a second transmission wheel fixedly connected to the first rotating seat, and a transmission belt connecting the first transmission wheel and the second transmission wheel. When the second gear rotates, it drives the first bevel gear to rotate through the meshing of the third gear and the fourth gear. When the first bevel gear rotates, it drives the first transmission wheel to rotate through the meshing of the first gear and the second bevel gear. When the first transmission wheel rotates, it drives the second transmission wheel to rotate through the transmission belt.

[0010] According to the preferred embodiment of this technical solution, the inner support assembly includes a rotating bracket rotatably connected to the mounting bracket and a second rotating seat rotatably connected to the rotating bracket. The cooling fan is mounted on the second rotating seat, and the connecting rod is movably connected to the second rotating seat.

[0011] In a preferred embodiment of this technical solution, the second rotating seat has a movable groove adapted to the connecting rod, and the connecting rod is movably connected to the movable groove.

[0012] According to the preferred embodiment of this technical solution, the filter assembly includes a mounting frame fixedly mounted on the mounting housing, a first filter plate mounted on the mounting frame, and a second filter plate mounted on the mounting housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The internal support assembly adopts a rotating design, which, together with the rotating drive assembly, realizes circular motion. This significantly optimizes the orientation adjustment capability of the cooling fan, allowing the cooling fan to flexibly switch orientations and cover a wider range. It completely breaks the limitation of the single airflow direction of traditional fixed fans, and can fully cover all core heat-generating areas of the internal motor body, effectively avoiding the problem of local heat accumulation under complex working conditions.

[0014] 2. The transmission component adopts a multi-stage gear and bevel gear design, which can flexibly change the power transmission direction. Through gear meshing and transmission belt cooperation, power is efficiently transmitted without the need for additional independent drive components, which greatly reduces the overall energy consumption of the drone and improves its endurance.

[0015] 3. The first and second filter plates of the filter assembly adopt an inclined vent design with the external opening facing downwards and the internal opening facing upwards. This has multiple practical advantages. The structure with the external opening facing downwards can reduce the direct fall of impurities such as dust, rainwater, and dew into the holes by gravity, allowing impurities attached to the outside of the holes to slide off naturally, effectively reducing the risk of filter plate clogging.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 6 This utility model provides an embodiment of a heat dissipation protection structure based on a drone motor, including a drone body 1, a main support assembly mounted on the drone body 1, a mounting shell 21 mounted on the main support assembly, a support leg 22 fixedly mounted on the mounting shell 21, a filter assembly and an inner support assembly mounted on the mounting shell 21, an inner motor body 25 and a main drive assembly mounted inside the mounting shell 21, a spiral blade body 26 mounted on the drive assembly, a transmission assembly mounted on the mounting shell 21, and a rotation drive assembly and a cooling fan 24 mounted on the inner support assembly. The transmission assembly is connected between the main drive assembly and the rotation drive assembly. The internal motor body 25 drives the spiral blade body 26 to rotate through the main drive assembly. When the main drive assembly is working, it drives the rotation drive assembly to work through the transmission assembly. When the rotation drive assembly is working, it rotates through the internal support assembly and the cooling fan 24. In this heat dissipation protection structure based on the drone motor, the inner motor body 25 is installed inside the mounting shell 21, the main bracket assembly fixes the mounting shell 21 to the drone body 1, and the support leg 22 provides stable support for the mounting shell 21. When the inner motor body 25 is started, it will drive the main drive assembly to start working. The main drive assembly directly drives the spiral blade body 26 to rotate to meet the power requirements of the drone flight. Meanwhile, during operation, the main drive assembly transmits power to the rotation drive assembly via a connected transmission assembly, causing the rotation drive assembly to operate synchronously. When the rotation drive assembly operates, it cooperates with the inner support assembly to drive the cooling fan 24 mounted on the inner support assembly to rotate. This causes the cooling fan 24 to continuously generate airflow while performing circular motion. As the airflow flows, the filter assembly mounted on the mounting housing 21 filters the airflow as it enters the housing 21, allowing the filtered airflow to flow smoothly through the inner motor body 25 and related components. In this entire structure, all components work together to ensure normal flight of the UAV while simultaneously cooling the motor.

[0020] Please see Figure 1 - Figure 2A further solution based on this embodiment is as follows: The main support assembly includes a fixed support 27 fixedly installed on the main body 1 of the drone and a folding support 28 rotatably connected to the fixed support 27. The mounting shell 21 is fixedly installed on the folding support 28. The fixed support 27 provides a stable mounting base for the folding support 28. The folding support 28 can rotate relative to the fixed support 27, thereby driving the mounting shell 21 installed on it to fold. When not in use, the folding support can be folded to reduce the size of the drone so that staff can store and carry it.

[0021] Please see Figure 2 A further solution based on this embodiment is as follows: The main drive assembly includes a first gear 29 fixedly connected to the output end of the inner motor body 25 and a second gear 210 meshing with the first gear 29. The second gear 210 is rotatably connected to the mounting housing 21. The spiral blade body 26 is fixedly mounted on the second gear 210. The inner motor body 25 is used to drive the first gear 29 to rotate. When the first gear 29 rotates, it drives the spiral blade body 26 to rotate through meshing with the second gear 210. The inner motor body 25 outputs power to drive the first gear 29 to rotate. The first gear 29 drives the second gear 210 to rotate synchronously through tooth surface meshing. The spiral blade body 26, which is fixedly connected to the second gear 210, rotates together with the second gear 210 to generate flight thrust. The gear meshing transmission method has high transmission efficiency and low power loss, ensuring that the power of the inner motor body 25 is stably transmitted to the spiral blade body 26. The meshing structure has high transmission accuracy. The second gear 210 is rotatably connected to the mounting housing 21, which enhances the structural stability and avoids deviation and shaking during transmission.

[0022] Please see Figure 2 - Figure 4 A further solution based on this embodiment is as follows: The rotation drive assembly includes a first rotating seat 218 rotatably connected to the mounting bracket 23 and a connecting rod 219 fixedly connected to the first rotating seat 218. The transmission assembly is connected between the second gear 210 and the first rotating seat 218. When the second gear 210 rotates, it drives the first rotating seat 218 to rotate through the transmission assembly. When the second gear 210 rotates, it transmits power to the first rotating seat 218 through the transmission assembly. The first rotating seat 218 rotates around the mounting bracket 23, and at the same time drives the connecting rod 219 fixedly connected to it to rotate synchronously, providing a power basis for the subsequent adjustment of the cooling fan 24, driving the cooling fan 24 to move, spreading the heat dissipation area, and making the airflow blow more comprehensively to the inner motor body 25.

[0023] Please see Figure 2 - Figure 4A further embodiment of this solution is as follows: The transmission assembly includes a third gear 211 fixedly mounted on the second gear 210, a fourth gear 212 meshing with the third gear 211, a first bevel gear 213 fixedly connected to the fourth gear 212, a second bevel gear 214 meshing with the first bevel gear 213, a first transmission wheel 215 fixedly connected to the second bevel gear 214, a second transmission wheel 216 fixedly connected to the first rotating seat 218, and a transmission belt 217 drivingly connecting the first transmission wheel 215 and the second transmission wheel 216. When the second gear 210 rotates, the first bevel gear 213 is driven to rotate through the meshing of the third gear 211 and the fourth gear 212. When the first bevel gear 213 rotates, it drives the first transmission wheel 215 to rotate through the meshing of the second bevel gear 214. When the first transmission wheel 215 rotates, it drives the second transmission wheel 216 to rotate through the transmission belt 217. Through the cooperation of multi-stage gears and bevel gears, the power direction can be flexibly switched, reducing the output end and lowering the energy consumption of the UAV.

[0024] Please see Figure 2 - Figure 4 A further solution based on this embodiment is as follows: the inner support assembly includes a rotating support 220 rotatably connected to the mounting bracket 23 and a second rotating seat 221 rotatably connected to the rotating support 220. The cooling fan 24 is mounted on the second rotating seat 221, and a connecting rod 219 is movably connected to the second rotating seat 221. The rotating support 220 can rotate around the mounting bracket 23, and the second rotating seat 221 can rotate relative to the rotating support 220. When the connecting rod 219 drives the second rotating seat 221 to move, combined with the rotation of the rotating support 220, the cooling fan 24 can be adjusted in multiple directions. The dual-rotation structure design gives the cooling fan 24 more flexible adjustment freedom, which can cover all core heat-generating areas of the motor and completely solve the problem of local heat accumulation.

[0025] Please see Figure 2 - Figure 4 A further solution based on this embodiment is as follows: The second rotating seat 221 is provided with a movable groove that is adapted to the connecting rod 219. The connecting rod 219 is movably connected to the movable groove. The connecting rod 219 can slide and rotate relative to each other in the movable groove. When the first rotating seat 218 drives the connecting rod 219 to move, the connecting rod 219 drives the second rotating seat 221 to rotate through the movable groove. At the same time, the movable groove provides the connecting rod 219 with a margin of movement. The adaptation design between the movable groove and the connecting rod 219 ensures smooth transmission between the connecting rod 219 and the second rotating seat 221 and avoids jamming.

[0026] Please see Figure 1 , Figure 5 - Figure 6A further solution based on this embodiment is as follows: the filter assembly includes a mounting frame 31 fixedly mounted on the mounting housing 21, a first filter plate 32 mounted on the mounting frame 31, and a second filter plate 33 mounted on the mounting housing 21. The vent holes on the first filter plate 32 and the second filter plate 33 are designed with an inclined shape, with the outer opening facing downwards and the inner opening facing upwards. This can significantly reduce the direct entry of impurities such as dust, rainwater, and dew into the holes. The impurities attached to the outside of the holes will naturally slide off due to gravity, reducing the risk of filter plate clogging.

[0027] Working principle: The fixed bracket 27 of the main support assembly is installed on the drone body 1. The folding bracket 28 cooperates with the fixed bracket 27 to support the mounting shell 21. The support leg 22 provides stable support for the mounting shell 21. The internal motor body 25 is located inside the mounting shell 21. When the drone needs to be started, the internal motor body 25 starts to run. Its output end drives the first gear 29 of the main drive assembly to rotate. The first gear 29 cooperates with the second gear 210 to drive the spiral blade body 26 fixed on the second gear 210 to rotate, thereby providing power for the drone to fly. While the first gear 29 drives the second gear 210 to rotate, the second gear 210 drives the third gear 211 on it to rotate synchronously. The third gear 211 and the fourth gear 212 cooperate to drive the first bevel gear 213 to rotate. The first bevel gear 213 and the second bevel gear 214 cooperate to drive the first transmission wheel 215 to rotate. The first transmission wheel 215 cooperates with the second transmission wheel 216 through the transmission belt 217 to drive the first rotating seat 218 of the rotation drive assembly to rotate. When the first rotating seat 218 rotates, it drives the connecting rod 219 on it to move. The connecting rod 219 moves in the movable groove of the second rotating seat 221 and cooperates with the rotating bracket 220 of the inner bracket assembly and the second rotating seat 221 to drive the cooling fan 24 installed on the second rotating seat 221 to rotate, so that the cooling fan 24 can perform multi-directional angle adjustment while generating airflow. During airflow, the filter assembly on the mounting shell 21 is fixed to the first filter plate 32 and the second filter plate 33 by the mounting frame 31. The airflow enters the interior of the mounting shell 21 through the vent holes on the first filter plate 32 and the second filter plate 33. The structure with the external opening facing down and the internal opening facing up guides the airflow to flow in a directional manner. The filtered airflow flows smoothly through the inner motor body 25 and related components to achieve heat dissipation. When the drone is finished using, the mounting shell 21 can be folded by rotating the folding bracket 28 relative to the fixed bracket 27, thereby reducing the overall size and making it easier to store and carry.
