[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Unmanned Aerial Vehicle (UAV), also known as unmanned aerial vehicle or remote-controlled aircraft, is an aircraft that does not require a human pilot to operate on board. Due to the small size of the drone, the battery that can be carried is small and the energy that can be stored is small, so drones face many challenges in terms of power endurance, especially in cold weather. The lower air temperature causes the activity of the chemical substances inside the drone's battery to decrease, the battery's internal resistance to increase, and the discharge capacity to weaken, which not only reduces the battery capacity, but may also cause the battery voltage to drop, affecting the flight of the drone.

[0050] In the related art, in order to maintain battery performance in a low-temperature environment, a heating film is provided for the battery of the drone, and the battery is heated by the heating film so that the battery is maintained at a suitable chemical reaction temperature. However, the use of the heating film consumes additional power, further reducing the endurance of the drone.

[0051] Therefore, an embodiment of the present invention provides a drone, which is equipped with a first heat pipe, a second heat pipe, a first magnetic block, a second magnetic block and a magnetic switch, and the first magnetic block is in contact with the second magnetic block when the magnetic switch is turned on, so as to heat the battery pack through the heat generated by the circuit module, so that the battery pack does not need to consume additional electrical energy through self-heating, thereby improving energy utilization, enhancing the endurance of the drone, and ensuring the stability of power supply.

[0052] Figure 1 is a schematic diagram of the structure of a drone according to an embodiment of the present invention. Figure 1 As shown, the drone has a heat dissipation module, a circuit module and a battery pack;

[0053] The heat dissipation module includes a fan and a first heat conducting pipe; the first heat conducting pipe is closely fitted with the circuit module to conduct the heat generated by the circuit module in a working state;

[0054] The drone also has a second heat-conducting pipe; the second heat-conducting pipe is tightly fitted with the battery pack;

[0055] A first magnetic block is arranged at the first position of the first heat conducting pipe; a second magnetic block is arranged at the second position of the second heat conducting pipe; the first magnetic block and the second magnetic block are arranged correspondingly, and when the magnetic switch of the drone is turned on, the first magnetic block contacts the second magnetic block.

[0056] Figure 1 The working principle of the drone shown is as follows:

[0057] The battery pack in the drone is used to provide the power required by the drone. The circuit module in the drone includes the drone's CPU (Central Processing Unit), VR (Virtual Reality, virtual reality technology, used for drone operation and training), MOS (Metal-Oxide-Semiconductor, metal oxide semiconductor field effect transistor, used for motor control, power management, etc.), IC (Integrated Circuit, integrated circuit, including various sensors, signal processors, communication chips, etc.), PCBA (Printed Circuit Board Assembly, printed circuit board assembly, as the physical carrier of each electronic component of the drone), TIM (Timer Input Module), etc. The circuit module generates heat when it is working. The first heat pipe in the heat dissipation module fits the circuit module tightly and can conduct the heat emitted by the circuit module when it is in working state. The fan in the heat dissipation module can generate airflow when it is turned on, enhance the air flow on the side of the first heat pipe, help the first heat pipe to dissipate heat, and then help the circuit module to dissipate heat. Optionally, the heat dissipation module also includes fins, which have good performance and are used to increase the heat exchange area of ​​the heat dissipation module and improve the heat dissipation efficiency.

[0058] The first position of the first magnetic block on the first heat-conducting tube corresponds to the second position of the second magnetic block on the second heat-conducting tube, so that when the magnetic switch of the drone is turned on, a magnetic force is generated between the first magnetic block and the second magnetic block, so that they attract and contact each other, and then the heat on the first heat-conducting tube is transferred from the first magnetic block to the second magnetic block, and then to the second heat-conducting tube. Since the second heat-conducting tube is tightly fitted with the battery pack, the second heat-conducting tube transfers the heat to the battery pack, thereby achieving heating of the battery pack by the heat generated by the circuit module in a low-temperature environment.

[0059] Optionally, the material of the first magnetic block and the second magnetic block may be magnetic metal.

[0060] Optionally, the magnetic switch may be a coil magnet switch.

[0061] Optionally, a graphite composite material is coated on the surface of the battery pack, and the high thermal conductivity of the graphite composite material is used to improve the thermal conductivity effect of the second heat pipe on the battery pack.

[0062] Optionally, the first heat conducting pipe and the first magnetic block are both fixed on a rack plate, so that the first magnetic block is arranged at a first position of the first heat conducting pipe through the rack plate.

[0063] In an optional embodiment, when the drone turns off the magnetic switch, the first magnetic block is separated from the second magnetic block. When the drone turns off the magnetic switch, the first magnetic block and the second magnetic block do not generate magnetic force, the first magnetic block and the second magnetic block are separated, and the heat of the first heat pipe is stopped from being transferred to the second heat pipe, that is, the battery pack is no longer heated by the heat generated by the operation of the circuit module.

[0064] The drone provided in this embodiment has a heat dissipation module, a circuit module and a battery pack; the heat dissipation module includes a fan and a first heat pipe; the first heat pipe is closely attached to the circuit module to conduct the heat generated by the circuit module in the working state; the drone also has a second heat pipe; the second heat pipe is closely attached to the battery pack; a first magnetic block is arranged at the first position of the first heat pipe; a second magnetic block is arranged at the second position of the second heat pipe; the first magnetic block and the second magnetic block are arranged correspondingly, and when the drone turns on the magnetic switch, the first magnetic block contacts the second magnetic block. By arranging the first heat pipe, the second heat pipe, the first magnetic block, the second magnetic block and the magnetic switch, and the first magnetic block and the second magnetic block contact when the magnetic switch is turned on, the heat generated by the circuit module in a low temperature environment can be conducted to the battery pack through the first heat pipe, the first magnetic block, the second magnetic block and the second heat pipe, so that the battery pack is heated by the heat generated by the circuit module, so that the battery pack does not need to consume additional electric energy through self-heating, improves energy utilization, improves the endurance of the drone, and ensures the stability of power supply.

[0065] According to an embodiment of the present invention, an embodiment of a method for controlling the temperature of a battery of a drone is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0066] In this embodiment, a method for controlling the temperature of a drone battery is provided, which is applied to the above Figure 1 The drone of the embodiment or any corresponding embodiment thereof, Figure 2 is a flow chart of a method for controlling the battery temperature of a drone according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0067] Step S201, when it is detected that the temperature of the battery pack of the drone is lower than a first threshold value, the magnetic switch is closed to make the first magnetic block contact with the second magnetic block.

[0068] The temperature of the battery pack of the drone can be measured by setting a temperature sensor for detecting the temperature of the battery pack, or by reading the temperature value in the battery management system corresponding to the battery pack itself. The first threshold is set according to the working performance of the battery pack of the drone at different temperatures. When the temperature of the battery pack is lower than the first threshold, the activity of the chemical substances inside the battery pack is low, the discharge capacity is weak, and the working performance is difficult to meet the working requirements of the drone. Therefore, when it is detected that the temperature of the battery pack of the drone is lower than the first threshold, the magnetic switch of the drone is closed, so that the magnetic force is generated between the first magnetic block and the second magnetic block, and they attract and contact each other, and then the heat on the first heat pipe is transferred from the first magnetic block to the second magnetic block, and then to the second heat pipe. Since the second heat pipe is tightly fitted with the battery pack, the second heat pipe transfers the heat to the battery pack, thereby achieving the heat generated by the circuit module working in a low temperature environment to heat the battery pack, so that the temperature of the battery pack can meet the normal working needs of the battery pack, and then meet the working needs of the drone.

[0069] The drone battery temperature control method provided in this embodiment sets a first threshold value on the basis of arranging a first heat pipe, a second heat pipe, a first magnetic block, a second magnetic block and a magnetic switch, and the first magnetic block and the second magnetic block are in contact when the magnetic switch is turned on. When it is detected that the temperature of the drone battery pack is lower than the first threshold value, the magnetic switch is closed to make the first magnetic block contact with the second magnetic block, so that the battery pack is heated by the heat generated by the circuit module, so that the battery pack does not need to consume additional electrical energy through self-heating, thereby improving energy utilization, enhancing the endurance of the drone, and ensuring power supply stability.

[0070] In this embodiment, a method for controlling the temperature of a drone battery is provided, which is applied to the above Figure 1 The drone of the embodiment or any corresponding embodiment thereof, Figure 3 is a flow chart of a method for controlling the battery temperature of a drone according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0071] Step S301, when it is detected that the temperature of the battery pack of the drone is lower than a first threshold value, the magnetic switch is closed to make the first magnetic block contact with the second magnetic block.

[0072] The first threshold is set according to the working performance of the battery pack of the drone at different temperatures. When the temperature of the battery pack is lower than the first threshold, the chemical substances inside the battery pack are less active, the discharge capacity is weak, and the working performance is difficult to meet the working requirements of the drone. Therefore, when it is detected that the temperature of the battery pack of the drone is lower than the first threshold, the magnetic switch of the drone is closed, so that the first magnetic block and the second magnetic block generate magnetic force and attract and contact each other, and then the heat on the first heat pipe is transferred from the first magnetic block to the second magnetic block, and then to the second heat pipe. Since the second heat pipe fits tightly with the battery pack, the second heat pipe transfers the heat to the battery pack, thereby achieving the heat generated by the circuit module working in a low temperature environment to heat the battery pack, so that the working performance of the battery pack will not be affected by the low temperature. The temperature of the heated battery pack can meet the normal working needs of the battery pack, and then meet the working requirements of the drone.

[0073] Step S302, when it is detected that the magnetic switch is closed, the fan in the heat dissipation module of the drone is turned off.

[0074] When it is detected that the magnetic switch is closed, it indicates that the battery pack needs to be heated by the heat generated by the circuit module, so the fan in the drone heat dissipation module is turned off to prevent the fan from dissipating heat for the first heat pipe, which causes the effect of the first heat pipe conducting heat to the battery pack to deteriorate.

[0075] Step S303, when the magnetic switch is in a closed state and it is detected that the temperature of the battery pack of the drone is higher than a second threshold value, the magnetic switch is disconnected to separate the first magnetic block from the second magnetic block.

[0076] The second threshold is set according to the working performance of the battery pack of the drone at different temperatures. When the temperature of the battery pack is higher than the first threshold, the chemical reaction speed inside the battery pack is accelerated, aging is accelerated, and thermal runaway or even safety hazards may occur. The working performance is difficult to meet the working requirements of the drone. When the magnetic switch is in a closed state and the temperature of the battery pack of the drone is higher than the second threshold, it indicates that there is no need to heat the battery pack at present, so the magnetic switch is disconnected, so that the first magnetic block and the second magnetic block do not generate magnetic force, the first magnetic block and the second magnetic block are separated, and the heat from the first heat pipe is stopped from being transferred to the second heat pipe, that is, the battery pack is no longer heated by the heat generated by the operation of the circuit module, ensuring that the working performance of the battery pack is not affected by excessive temperature, thereby ensuring the normal operation of the drone.

[0077] Optionally, when it is detected that the magnetic switch is disconnected and the fan of the heat dissipation module of the drone is in an off state, the fan of the heat dissipation module of the drone is turned on. When it is detected that the magnetic switch is disconnected, it indicates that the battery pack does not need to be heated by the heat generated by the circuit module, and the circuit module itself needs to dissipate heat to maintain working performance, so the fan in the heat dissipation module of the drone is turned on to help the first heat pipe dissipate heat, and then help the circuit module dissipate heat to meet the normal working requirements of the drone.

[0078] Optionally, when the fan in the heat dissipation module of the drone is in an off state, the temperature of the circuit module of the drone is monitored in real time, and if the temperature of the circuit module of the drone is higher than a third threshold, the fan in the heat dissipation module of the drone is turned on. The third threshold is set according to the working performance of the circuit module of the drone at different temperatures. When the temperature of the circuit module is higher than the third threshold, the circuit module will cause the working performance to decline due to the excessively high temperature, and it is difficult to meet the working requirements of the drone. Therefore, the fan in the heat dissipation module of the drone is turned on to help the first heat pipe dissipate heat, and then help the circuit module dissipate heat to meet the normal working requirements of the drone.

[0079] The drone battery temperature control method provided in this embodiment sets a first threshold value on the basis of arranging a first heat pipe, a second heat pipe, a first magnetic block, a second magnetic block and a magnetic switch, and the first magnetic block and the second magnetic block are in contact when the magnetic switch is turned on. When it is detected that the temperature of the drone battery pack is lower than the first threshold value, the magnetic switch is closed to make the first magnetic block contact with the second magnetic block, so that the battery pack is heated by the heat generated by the circuit module, so that the battery pack does not need to consume additional electrical energy through self-heating, thereby improving energy utilization, enhancing the endurance of the drone, and ensuring power supply stability.

[0080] As one or more specific application embodiments of the embodiments of the present invention, the optimal implementation scheme or the scheme that the inventor most wants to embody is described below in combination with specific application scenarios.
