[0035] See also Figures 1 to 3 An embodiment of the present application provides a drone 100, comprising a body 1, a connecting arm 2, a blade 3, a heating component 4 and a temperature sensor 5. Among them:

[0036] One end of the connecting arm 2 is connected to the body 1, and the blade 3 is rotatably connected to the end of the connecting arm 2 facing away from the body 1. The heating component 4 includes a heating element 41 and a supporting element 42. The heating element 41 is arranged on the air inlet side of the blade 3 and is spaced apart from the blade 3. The heating element 41 is connected to the body 1 through the supporting element 42. The temperature sensor 5 is electrically connected to the heating element 41. The temperature sensor 5 is used to detect the temperature of the blade 3. The temperature sensor 5 can control the start of the heating element 41 according to the temperature of the blade 3.

[0037] In the above-mentioned drone 100, the heating element 41 is arranged on the air inlet side of the blade 3 and is arranged opposite to the blade 3. The temperature sensor 5 is electrically connected to the heating element 41, and the temperature sensor 5 can not only detect the temperature of the blade 3, but also control the start of the heating element 41 according to the detected temperature of the blade 3. This makes it possible that during the flight of the drone 100, the airflow formed by the operation of the blade 3 will pass through the heating element 41, and the temperature sensor 5 can detect the temperature of the blade 3 in real time, so that when the drone 100 reaches a lower temperature environment, the temperature sensor 5 can control the start of the heating element 41 according to the actual temperature of the blade 3 to heat the air blowing toward the blade 3. Specifically, when the temperature sensor 5 detects that the temperature of the blade 3 is lower than the critical temperature value, the temperature sensor 5 controls the start of the heating element 41 to heat, so that the heating element 41 can heat the air on the air inlet side of the blade 3. In this way, the air attracted by the blade 3 will be heated by the heating element 41, and the heated air will automatically heat up and melt ice when it is flushed to the blade 3, thereby avoiding ice covering the blade 3. Therefore, when the UAV 100 cruises in the cold air layer, there will be no problem of ice covering the blades 3.

[0038] Illustratively, the critical temperature value may be set according to actual conditions, for example, it may be 0° C., or a value higher than 0° C.

[0039] Exemplarily, the temperature sensor 5 can also control the heating element 41 to be turned off according to the temperature of the blade 3. In this way, the temperature sensor can control the start and stop of the heating element according to the actual detected blade temperature to effectively ensure that the blade is not covered with ice.

[0040] Specifically, when the drone 100 is flying and the heating element 41 is in the off state, if the temperature sensor 5 detects that the temperature of the blade 3 is higher than the above-mentioned critical temperature value, the temperature sensor 5 controls the heating element 41 to remain in the off state to reduce resource waste. Further, when the drone 100 is flying and the heating element 41 is in the on state, if the temperature sensor 5 detects that the temperature of the blade 3 is higher than the maximum heating temperature value, such as 3°C, 5°C or 10°C, the temperature sensor 5 controls the heating element 41 to be turned off to reduce resource consumption under the premise of ensuring that the blade is not covered with ice.

[0041] Schematically, the temperature sensor 5 is disposed on the body 1 ; alternatively, the temperature sensor 5 may also be disposed on the connecting arm 2 or the blade 3 .

[0042] Optionally, in one embodiment, Figures 1 to 3As shown, the number of connecting arms 2, the number of blades 3 and the number of heating components 4 are all multiple, and multiple connecting arms 2 are arranged at intervals along the circumference of the body 1. The connecting arms 2, blades 3 and heating components 4 are arranged one-to-one, and each heating element 41 is electrically connected to the temperature sensor 5. The temperature sensor 5 can control the activation of multiple heating elements 41 according to the detected temperature of the blades 3. In this way, the drone 100 can fly more smoothly under the joint action of multiple blades 3, which is conducive to improving the stability and reliability of the drone 100 during flight. Among them, since the heating components 4 correspond to the blades 3 one-to-one, during the flight of the drone 100, the heating components 4 can effectively heat the air blowing to the blades 3 under the control of the temperature sensor 5 to avoid the problem of ice covering each blade 3, thereby ensuring the normal operation of the drone 100.

[0043] Optionally, since the external environment of each blade 3 is roughly the same during flight, the number of temperature sensors 5 can be only one, and it is only necessary for the temperature sensor 5 to reliably detect the temperature of one of the blades 3; or, there can be multiple temperature sensors 5, and the multiple temperature sensors 5 correspond one-to-one to the multiple blades 3 and the multiple heating components 4, and each temperature sensor 5 can control the start-up of the corresponding heating element 41 according to the temperature of the corresponding blade 3.

[0044] Preferably, Figures 1 to 3 As shown, the number of connecting arms 2, the number of blades 3 and the number of heating components 4 are all four, and the four connecting arms 2 are evenly spaced along the circumference of the body 1. This is beneficial to improving the stability and reliability of the drone 100 during flight and ensuring the miniaturization of the structure of the drone 100.

[0045] In one embodiment, in combination Figure 3 and Figure 4 As shown, the support member 42 includes a fixed sleeve 421 and a connecting rod 422. The fixed sleeve 421 is arranged on the air inlet side of the blade 3. The fixed sleeve 421 is provided with a penetrating air guide channel 421a. The air guide channel 421a is arranged opposite to the blade 3. The heating member 41 is arranged in the air guide channel 421a. One end of the connecting rod 422 is connected to the body 1, and the other end is connected to the fixed sleeve 421. In this way, when the blade 3 rotates, the air located on the upper side of the blade 3 can flow to the blade 3 through the air guide channel 421a, so as to ensure that the drone 100 can fly under the action of the blade 3. Among them, since the heating member 41 is arranged in the air guide channel 421a, the heat generated by the heating member 41 is not easy to diffuse, so that when the heating member 41 is working, the heating member 41 can effectively heat the air passing through the air guide channel 421a, improve the heating efficiency, and then ensure that the temperature of the air blowing to the blade 3 is high, so as to enhance the heating effect of the blade and avoid ice covering the blade 3.

[0046] Further, in one embodiment, if Figure 3 As shown, the heating element 41 includes a connecting rod 412 and a plurality of heating rods 411, and the plurality of heating rods 411 are arranged at intervals along the circumference of the air guide channel 421a, and each heating rod 411 extends radially along the air guide channel 421a, and one end of each heating rod 411 is connected to the fixing sleeve 421, and the other end is connected to the connecting rod 412, and the temperature sensor 5 is electrically connected to the plurality of heating rods 411, and the temperature sensor 5 can control the activation of the plurality of heating rods 411 according to the temperature of the blade 3. In this way, the plurality of heating rods 411 can be reliably arranged in the air guide channel 421a through the interaction with each other, so that the plurality of heating rods 411 can work simultaneously, thereby effectively improving the heating efficiency, increasing the temperature rise rate of the air, and ensuring that the temperature of the air blowing to the blade 3 is high, so as to avoid ice covering the blade 3.

[0047] Optionally, in one embodiment, the side of the heating rod 411 facing away from the blade 3 is in an arc shape that bulges toward the side facing away from the blade 3. Since the side of the heating rod 411 facing away from the blade 3 is in an arc shape, when air enters the air guide channel 421a from the end of the air guide channel 421a facing away from the blade 3, the airflow can flow smoothly toward the side of the blade 3 under the guidance of the arc surface of the heating rod 411, so as to reduce the influence of the heating rod 411 on the air circulation.

[0048] Schematically, the cross section of the heating rod 411 may be circular.

[0049] In other embodiments, the heating element 41 may also include a plurality of heating wires, which are interconnected to form a mesh structure. The plurality of heating wires are all fixed in the air guide channel 421a and are all electrically connected to the temperature sensor 5. The temperature sensor 5 can control the heating of the plurality of heating wires according to the temperature of the blade 3.

[0050] In one embodiment, in combination Figure 3 and Figure 4As shown, the heating assembly 4 also includes a lifting drive 43, which is arranged on the body 1 and is drivingly connected to the connecting rod 422. The lifting drive 43 is electrically connected to the temperature sensor 5. The temperature sensor 5 can control the start of the lifting drive 43 according to the temperature of the blade 3, so that the heating element 41 can move closer to or away from the blade 3 under the drive of the lifting drive 43. In this way, during the heating process of the heating element 41, the temperature sensor 5 can drive the lifting drive 43 to drive the heating element 41 to move along the relative direction of the blade 3 and the heating element 41 according to the detected temperature of the blade 3, so as to adjust the distance between the heating element 41 and the blade 3, thereby ensuring that the heating element 41 can heat the blade 3 to a suitable temperature, so as to avoid excessive heating of the blade 3 due to long-term close-distance heating, and avoid the temperature rise not meeting the standard due to long-distance heating, so as to effectively ensure that the blade 3 can rotate reliably and ensure the reliability of the operation of the drone 100.

[0051] Furthermore, in one embodiment, in combination Figure 3 and Figure 4 As shown, the lifting drive member 43 includes a lifting motor 431, a screw 432 and a lifting member 433. The lifting motor 431 is fixedly connected to the body 1, and the lifting motor 431 is electrically connected to the temperature sensor 5. The relative direction between the blade 3 and the heating member 41 is consistent with the extension direction of the screw 432. One end of the screw 432 is driven and connected to the lifting motor 431, and the other end is threadedly connected to the lifting member 433. The lifting member 433 is fixedly connected to the connecting rod 422. The temperature sensor 5 can control the start of the lifting motor 431 according to the temperature of the blade 3, so that the heating member 41 moves closer to or away from the blade 3. In this way, the screw 432 can drive the lifting member 433 to drive the heating member 41 and the support member 42 to make stepless adjustments along the extension direction of the screw 432 under the drive of the lifting motor 431, so that the lifting drive member 43 can accurately adjust the distance between the heating member 41 and the blade 3 under the action of the temperature sensor 5, so as to ensure that the blade 3 can be heated to a suitable heating temperature.

[0052] Optionally, in one embodiment, in combination Figure 3 and Figure 4As shown, the lifting drive member 43 further includes a sleeve 434, which is sleeved on the lifting motor 431, the screw rod 432 and the outer periphery of the lifting member 433. A slide rail 434a extending along the extension direction of the screw rod 432 is arranged in the sleeve 434, and the lifting member 433 is provided with a slide groove, which is slidably matched with the slide rail 434a. In this way, the sleeve 434 can protect the lifting drive member 43 at the outer periphery of the lifting drive member 43 to prevent external objects from interfering with the lifting drive member 43 driving the heating member 41. At the same time, the sliding sleeve 434 can cooperate with the sliding rail 434a and the sliding groove to enable the lifting member 433 to stably move up and down along the extension direction of the screw 432, so that the heating member 41 and the fixing sleeve 421 can stably move closer to or away from the blade 3, so that when adjusting the spacing, the air guide channel 421a will not be misaligned with the blade 3, ensuring that the airflow formed by the air absorbed by the blade 3 can pass through the air guide channel 421a, so that the heating component 4 can effectively ensure that the blade 3 is not covered with ice.

[0053] Schematically, the number of the slide rails 434a and the number of the slide slots can both be multiple, and the multiple slide rails 434a are arranged at intervals along the circumference of the sliding sleeve 434, and the slide slots and the slide rails 434a are slidably matched one by one. Optionally, the number of the slide slots and the number of the slide rails 434a are both two, and the two slide rails 434a are arranged opposite to each other.

[0054] In other embodiments, the lifting drive member 43 may also include a telescopic cylinder, which is fixed on the machine body 1 and has a telescopic end that is drivingly connected to the connecting rod 422 .

[0055] In one embodiment, Figure 2 and Figure 3 As shown, the drone 100 further includes a protection ring 6 and a plurality of protection rods 7, the plurality of protection rods 7 are arranged at intervals along the circumference of the blades 3 and are arranged at intervals with the blades 3, one end of the plurality of protection rods 7 are fixedly connected to the fixing sleeve 421, and the other end are connected to the protection ring 6. In this way, the protection rods 7, the protection rods 7 and the fixing sleeve 421 can build a protection structure on the periphery of the blades 3, thereby preventing the drone 100 from having installation accidents due to the blades 3 contacting external objects during flight, thereby improving the safety of the drone 100 during flight.

[0056] In one embodiment, Figure 2 and Figure 3 As shown, the drone 100 further includes a support leg 8, which is disposed on the body 1 and is used to support the drone 100 on the ground. In this way, the drone 100 can be stopped on the ground by the support leg 8 when not performing a flight mission.

[0057] Optional, such as Figure 3 As shown, the number of the supporting legs 8 may be two, and the two supporting legs 8 are arranged opposite to each other and spaced apart.

[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
