[0002] As an efficient and convenient aerial tool, drones have been widely used in many fields.

[0003] With the continuous development of drone technology and the expansion of its application scenarios, drones are increasingly packed with electronic components. When drones are running under high load for extended periods, the heat generated by these electronic components can cause overheating, performance degradation, or even damage. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this disclosure provides a movable device.

[0005] According to an embodiment of this disclosure, a movable device is provided, comprising:

[0006] The support portion has a heat dissipation air duct extending along the roll axis direction of the movable device;

[0007] The battery module is disposed on the support portion;

[0008] A control module is disposed on the support unit, and the battery module, the support unit, and the control module are stacked together.

[0009] The battery module and the control module are respectively located on both sides of the heat dissipation duct along the stacking direction, and both the battery module and the control module are in heat transfer contact with the heat dissipation duct.

[0010] In some embodiments, the battery module is disposed on the first surface of the support portion along the stacking direction, and a portion of the first surface is recessed to form a first groove, and the heat dissipation duct includes the first groove.

[0011] In some embodiments, the first groove includes a first sidewall and a second sidewall, the first sidewall and the second sidewall being arranged along the axial direction of the pitch axis of the movable device, and the second sidewall being located on the side of the first sidewall away from the geometric center of the bearing portion.

[0012] In the axial direction of the roll shaft, the length of the first sidewall is greater than the length of the second sidewall.

[0013] In some embodiments, at least one end of the first groove is provided with a chamfered structure along the roll axis direction.

[0014] In some embodiments, in the stacking direction, the second surface of the support portion is recessed to form a second groove, and the projection of the second groove along the stacking direction at least partially overlaps with the projection of the heat dissipation duct along the stacking direction;

[0015] The control module is located within the second groove.

[0016] In some embodiments, the support portion is provided with a through hole, which penetrates the support portion along the stacking direction to connect the second groove and the heat dissipation duct.

[0017] In some embodiments, the movable device further includes a heat sink disposed in the through hole and located between the control module and the battery module.

[0018] In some embodiments, the heat sink includes a connected main body structure and fins, the main body structure being disposed in the second groove, and the fins passing through the through hole and extending into the heat dissipation duct.

[0019] In some embodiments, the heat sink is detachably connected to the support portion; and / or,

[0021] In some embodiments, in the stacking direction, a third groove is provided on the side of the heat sink facing the control module, and the control module is disposed in the third groove.

[0022] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: the battery module and the control module are respectively disposed on both sides of the support part along the stacking direction, which lowers the center of gravity of the whole machine and facilitates the control of the movement posture of the movable device; in addition, both the battery module and the control module are in heat transfer contact with the heat dissipation duct in the support part, and the heat dissipation duct extends along the roll axis of the movable device. The movable device can dissipate heat by the external air entering the heat dissipation duct during movement, without the need to set up an active heat dissipation device, simplifying the overall structure, reducing the overall size, and lowering the center of gravity.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] In related technologies, active cooling devices such as electric fans and flying towers are usually installed in drones for heat dissipation. However, the large size of electric fans and flying towers leads to a large overall size of the drone and raises the center of gravity of the drone, which is not conducive to controlling the attitude of the drone.

[0039] To address the problems existing in related technologies, this disclosure provides a mobile device including a support unit, a battery module, and a control module. The support unit has a heat dissipation duct extending along the roll axis of the mobile device. The battery module, support unit, and control module are stacked, with the battery module and control module located on opposite sides of the heat dissipation duct along the stacking direction, and both the battery module and control module are in heat-transfer contact with the heat dissipation duct. In this disclosure, the battery module and control module are located on opposite sides of the support unit along the stacking direction, lowering the overall center of gravity and facilitating control of the mobile device's movement. Furthermore, since both the battery module and control module are in heat-transfer contact with the heat dissipation duct in the support unit, and the heat dissipation duct extends along the roll axis of the mobile device, the mobile device can dissipate heat by allowing external air to enter the heat dissipation duct during movement, eliminating the need for an active cooling device, simplifying the overall structure, reducing the overall size, and lowering the center of gravity.

[0040] According to an exemplary embodiment of this disclosure, such as Figures 1 to 3 As shown, this embodiment provides a mobile device, such as a remote-controlled drone, a remote-controlled car, or a boat. Remote-controlled drones, remote-controlled cars, and remote-controlled boats may have similar internal component layouts. In this embodiment, a drone is used as an example to explain the technical solution.

[0041] like Figure 1 As shown, the mobile device includes a support unit 10, such as the frame of a drone. The frame serves as the main framework of the drone, supporting and mounting other components, including arms and drive units, landing gear, battery module 20 (described in detail later), and control module 30 (described in detail later). The support unit 10 is typically made of lightweight, high-strength materials such as carbon fiber and aluminum alloy to ensure high overall mechanical structural strength while maintaining a low weight. See also... Figure 1 The bearing part 10 is provided with a section along the roll axis direction of the movable device ( Figure 2 and Figure 3 The heat dissipation duct 11, which extends in the y-direction (as shown in the diagram), is understood to mean that the direction of travel of the movable device is parallel to or forms a certain angle with the roll axis direction in most cases. For example, when the movable device moves straight forward, the bearing part 10 will generate relative motion with the external air in the y-direction, and the external air can move along the roll axis direction (as shown in the diagram) without losing kinetic energy. Figure 2 As shown in the y direction, the air enters the movable device through the heat dissipation duct 11. The faster the airflow, the higher the heat dissipation efficiency, thus significantly improving the heat dissipation efficiency.

[0042] Additionally, it should be noted that multiple heat dissipation ducts 11 can be provided in the bearing section 10, see reference. Figure 1 and Figure 2This illustrates the case where two heat dissipation ducts 11 are arranged symmetrically. In some alternative embodiments, for example, three or more heat dissipation ducts 11 may be provided; however, it is necessary to avoid having multiple ducts along the thickness direction of the support portion 10. Figure 2 The z-direction shown is configured to avoid excessive hollow structures in the support part 10, which would reduce the structural strength.

[0043] like Figure 1 As shown, the portable device includes a battery module 20, which is mounted on the support portion 10. In one example, the support portion 10 has a battery compartment, and the battery module 20 and the battery compartment are detachable. It is understood that when the battery module 20 discharges to power the portable device, a chemical reaction occurs inside the battery module 20, releasing a large amount of heat, causing the temperature of the battery module 20 to rise. See also... Figures 1 to 3 The battery module 20 is in heat transfer contact with the heat dissipation duct 11 of the support part 10. The heat generated by the battery module 20 can be transferred into the heat dissipation duct 11 and discharged to the external environment along the extension direction of the heat dissipation duct 11, thereby achieving heat dissipation of the battery module 20.

[0044] like Figure 1 and Figure 3 As shown, the movable device also includes a control module 30, which is mounted on the support unit 10. The control module 30 has multiple functions and may include electronic components 32 such as a communication unit, a positioning unit, a processing chip, and various sensors, as well as a circuit board 31 for supporting these electronic components 32. The control module 30 also generates heat during operation, for example, due to resistance losses in the circuit wires. (See reference...) Figure 1 The control module 30 makes heat transfer contact with the heat dissipation duct 11 of the support part 10. The heat generated by the control module 30 can be transferred into the heat dissipation duct 11 and discharged to the external environment along the extension direction of the heat dissipation duct 11, thereby achieving heat dissipation of the control module 30.

[0045] Among them, see Figure 1 , Figure 3 and Figure 4 The battery module 20, control module 30, and support unit 10 are stacked, with the battery module 20 and control module 30 arranged along the stacking direction ( Figure 2As shown in the z-direction, the battery module 20 and control module 30 are respectively disposed on the upper and lower sides of the support part 10, that is, the battery module 20 and control module 30 are respectively disposed on the upper and lower sides of the heat dissipation duct 11 along the stacking direction. It can be understood that distributing the control module 30 and battery module 20 on the upper and lower sides of the support part 10, compared to distributing the control module 30 and battery module 20 on the same side of the support part 10, can lower the center of gravity of the whole machine, which is beneficial to controlling the movement posture of the movable device. Furthermore, this arrangement can achieve a reduction in the thickness direction of the support part 10 (in the z-direction). Figure 2 In the z-direction shown, only a single heat dissipation duct 11 is provided, which simultaneously dissipates heat from the battery module 20 and the control module 30, thereby simplifying the structural design of the support part 10 and avoiding the structural strength of the support part 10 being insufficient due to the provision of multiple heat dissipation ducts 11 along the thickness direction.

[0046] In this embodiment, the battery module 20 and the control module 30 are respectively disposed on both sides of the support portion 10 along the stacking direction, which lowers the center of gravity of the whole machine and facilitates the control of the movement posture of the movable device. Furthermore, both the battery module 20 and the control module 30 are in heat transfer contact with the heat dissipation duct 11 in the support portion 10. The heat dissipation duct 11 extends along the roll axis of the movable device, and the movable device can dissipate heat by external air entering the heat dissipation duct 11 during movement, without the need to set up an active heat dissipation device, which simplifies the overall structure, reduces the overall size, and lowers the center of gravity.

[0047] In one exemplary embodiment, such as Figure 1 As shown, this embodiment of the present disclosure provides a mobile device, which includes a support part 10, a battery module 20 and a control module 30. The support part 10 has a heat dissipation duct 11 extending along the roll axis of the mobile device. The battery module 20 and the control module 30 are stacked. The battery module 20 and the control module 30 are respectively disposed on both sides of the heat dissipation duct 11 along the stacking direction, and both the battery module 20 and the control module 30 are in heat transfer contact with the heat dissipation duct 11.

[0048] Among them, such as Figure 3 As shown, the support portion 10 includes a first surface 10a. When the movable device is placed upright, the first surface 10a can be the top surface of the support portion 10. The battery module 20 is positioned along the stacking direction ( Figure 3As shown in the z-direction, a first groove 111 is formed by a portion of the first surface 10a of the support portion 10 recessed in the opposite direction of the z-direction. In the assembled state, the bottom surface of the battery module 20 is in contact with the first surface 10a of the support portion 10, thereby forming a heat dissipation duct 11 by the bottom surface of the battery module 20 and the first groove 111. In some optional embodiments, the first surface 10a of the support portion 10 can also be the bottom surface of the support portion 10, so that the battery module 20 is disposed below the support portion 10 and the control module 30 is located above the support portion 10, which will not be described in detail.

[0049] In this embodiment, a first groove 111 is formed by recessing part of the surface of the support portion 10, which enables the battery module 20 to directly form heat transfer contact with the heat dissipation duct 11 and ensures a reliable connection between the battery module 20 and the support portion 10.

[0050] Among them, such as Figure 1 and Figure 2 As shown, the support portion 10 is provided with two first grooves 111, which are symmetrically arranged about the roll axis. Each first groove 111 includes a first sidewall 1111 and a second sidewall 1112. The first sidewall 1111 and the second sidewall 1112 are arranged along the axial direction of the pitch axis of the movable device. The two ends of the first sidewall 1111 and the second sidewall 1112 define the air inlet and air outlet of the heat dissipation duct 11. (See reference...) Figure 2 The second sidewall 1112 is located away from the first sidewall 1111. Figure 2 On one side of the geometric center of the bearing portion 10 (shown in the x direction), and in the axial direction of the roll axis ( Figure 2 In the x direction shown, the length of the first sidewall 1111 is greater than the length of the second sidewall 1112, so that the air inlet defined by the first sidewall 1111 and the second sidewall 1112 faces the left front or right front of the movable device. When the movable device flies to the left front, right front, or left and right, it can ensure that external air can enter the heat dissipation duct 11 to dissipate heat from the control module 30 and the electromagnetic module.

[0051] In this embodiment, by adaptively configuring the sidewall of the first groove 111 that constitutes the heat dissipation duct 11, the air inlet of the heat dissipation duct 11 faces the oblique front of the movable device, so that air enters the heat dissipation duct 11 in various unique postures of the movable device, thereby increasing the utilization rate of external air and improving the heat dissipation effect.

[0052] Among them, such as Figure 2 As shown, along the axial direction of the roll axis of the movable device ( Figure 2As shown in the y-direction, at least one end of the first groove 111 is provided with a chamfered structure 112. The end of the first groove 111 forms the air inlet and air outlet of the heat dissipation duct 11. By providing the chamfered structure 112, the size of the air inlet and air outlet can be increased, thereby increasing the air intake and effectively improving the heat dissipation effect. The chamfered structure 112 can be a rounded corner structure or a beveled corner structure, and is not limited in this embodiment.

[0053] Additionally, it should be noted that the reference... Figure 2 In this embodiment, the supporting part 10 is provided with a first support arm 14. When the movable device moves forward in a straight line, the first support arm 14, located in front of the heat dissipation duct 11, will obstruct the external air. Therefore, the movable device provided in this embodiment is tilted when moving, that is, there is a certain angle (e.g., 3° ​​to 5°) between the roll axis and the direction of travel, so that the external air avoids the first support arm 14 and enters the heat dissipation duct 11. The movable device provided in this embodiment flies in a tilted posture, so that the external air avoids the first support arm 14 used to improve the structural strength of the supporting part 10. By providing a chamfered structure 112 at the end of the first groove 111, the chamfered structure 112 changes the opening orientation of the heat dissipation duct 11 to a certain extent, allowing more external air to enter the heat dissipation duct 11 at high speed, thereby improving the heat dissipation effect.

[0054] In one exemplary embodiment, such as Figure 1 As shown, this embodiment of the present disclosure provides a mobile device, which includes a support part 10, a battery module 20 and a control module 30. The support part 10 has a heat dissipation duct 11 extending along the roll axis of the mobile device. The battery module 20 and the control module 30 are stacked. The battery module 20 and the control module 30 are respectively disposed on both sides of the heat dissipation duct 11 along the stacking direction, and both the battery module 20 and the control module 30 are in heat transfer contact with the heat dissipation duct 11.

[0055] The movable device provided in this embodiment may include any structure or component of the movable device provided in the above embodiments.

[0056] Among them, such as Figure 3 As shown, in the stacking direction of the support part 10, the battery module 20 and the heat dissipation module ( Figure 3In the z-direction shown, a second groove 12 is formed in the second surface 10b of the support portion 10. The control module 30 is disposed within the second groove 12. In the assembled state, only a small portion of the control module 30 protrudes from the second surface 10b of the support portion 10. In some cases, when the thickness of the control module 30 is sufficiently small, it can even be completely contained within the second groove 12. By providing the second groove 12, the internal space of the support portion 10 is fully utilized, reducing the stacking height of the support portion 10, the control module 30, and the battery module 20, which helps to lower the center of gravity of the entire device. (See reference...) Figures 1 to 3 The projection of the second groove 12 of the support portion 10 along the stacking direction overlaps at least partially with the projection of the heat dissipation duct 11 along the stacking direction, so as to enable the battery module 20 and the control module 30 to share the same heat dissipation duct 11.

[0057] Among them, such as Figure 1 and Figure 3 As shown, the support portion 10 has a through hole 13, which extends through the support portion 10 along the stacking direction to connect the second groove 12 and the heat dissipation duct 11. By providing the through hole 13, the control module 30 is connected to the heat dissipation duct 11, thereby improving the heat dissipation effect on the control module 30.

[0058] In some embodiments (not shown in the figures), the control module can be in direct contact with the heat dissipation duct through a through hole, and the control module is cooled by direct blowing of external air.

[0059] In other embodiments, such as Figure 1 and Figure 2 As shown, a heat sink 40 can be installed in the through hole 13. The heat sink 40 is disposed between the control module 30 and the heat dissipation duct 11. One side of the heat sink 40 contacts the control module 30, and the other side of the heat sink 40 extends into the heat dissipation duct 11 through the through hole 13. The heat sink 40 is usually made of a high thermal conductivity material, which can quickly transfer the heat generated by the control module 30 to the heat dissipation duct 11, thereby achieving cooling.

[0060] Among them, see Figures 1 to 3 The heat sink 40 includes a connected main body structure 41 and fins 42. The main body structure 41 is disposed in the second groove 12, and the fins 42 pass through the through hole 13 and extend into the heat dissipation duct 11. The shape of the main body structure 41 can be the same as the shape of the control module 30 to dissipate heat and evenly distribute heat in various areas of the control module 30. Furthermore, the side of the main body structure 41 facing the control module 30 can be configured to have multiple heights so that the main body structure 41 can be connected to electronic components of various sizes in the control module 30, thereby improving the heat dissipation effect and space utilization.

[0061] Among them, see Figure 1 and Figure 3The heat sink 40 can be detachably connected to the support unit 10, and the control module 30 can be detachably connected to the heat sink 40. The detachable connection method can be any of the following: fastener 50 (screw), snap-fit ​​connection, or adhesive connection. In this embodiment, the support unit 10, the heat sink 40, and the control device adopt a modular design, which facilitates maintenance and improves production efficiency.

[0062] Among them, see Figure 3 A third groove 412 is provided on the side of the heat sink 40 facing the control module 30, and the control module 30 is disposed in the third groove 412. This arrangement helps to reduce the size of the heat sink 40 and the control module 30 after stacking. The third groove 412 can also reduce the thickness of the heat sink 40. Figure 3 (as shown in the z-direction), allowing the heat generated by the control module 30 to reach the heat dissipation duct 11 more quickly, thus improving the heat dissipation effect. In some alternative embodiments, the structure used to form the third groove 412 can be configured to protrude from the control module 30, providing protection for the control module 30.

[0063] In some alternative implementations, see Figure 3 Different areas of the third groove 412 are configured to have different depths. For example, the area of ​​the third groove 412 that faces the electronic component 32 has a deeper depth, while the part of the third groove 412 that only faces the circuit board 31 has a shallower depth. This ensures that both the circuit board 31 and the electronic component 32 can directly contact the heat sink 40, thereby improving heat dissipation efficiency. It also increases the space utilization of the third groove 412 and improves the integration of the movable device.
