Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0027] In the description of the present application, “plurality” means two or more, unless otherwise clearly defined.

[0028] Please also refer to Figures 1 to 6 Now let’s look at the foldable drone provided in the embodiments of this application.

[0029] refer to Figures 1 to 6The foldable drone described in the present application includes a fuselage 100, a rotary arm 200 that can be folded and stored at the side of the fuselage 100, a flight control module 300 arranged in the fuselage 100, and a lift assembly 400 arranged at the free end of each rotary arm 200 and electrically connected to the flight control module 300.

[0030] The lift assembly 400 may include a motor 410 whose axis is parallel to the height direction and a blade 420 arranged on the rotating shaft of the motor 410 .

[0031] The fuselage 100 has a hollow storage layer 101 formed along its height, which is open to the outside. Specifically, the fuselage 100 can be assembled from multiple layers of panels, with the storage layer 101 formed in the space between two adjacent layers of panels. It is understood that the aforementioned flight control module 300 is mounted on the panels and is located at a different height than the storage layer 101.

[0032] A driving assembly 500 is provided in the storage layer 101 , and each driving assembly 500 is used to pull two rotating arms 200 opposite to each other in the width direction to be synchronously stored on both sides of the fuselage 100 , or to push two rotating arms 200 opposite to each other in the width direction to be synchronously unfolded from both sides of the fuselage 100 .

[0033] That is, each driving assembly 500 is used to drive a pair of rotary arms 200 that are arranged opposite to each other in the width direction to expand or retract. In some embodiments, two pairs of rotary arms 200 are provided, and two driving assemblies 500 are provided.

[0034] By setting a drive component 500 in the storage layer 101, and the drive component 500 is linked to the rotary arm 200, the deployment of a pair of rotary arms 200 can be achieved only by operating the drive component 500, and for the storage of a pair of rotary arms 200, continuing to push any rotary arm 200 in the pair of rotary arms 200 can synchronously drive the storage of the other rotary arm 200. Compared with the conventional design method in which each rotary arm 200 needs to be folded, the drone of the embodiment of the present application has a more convenient and efficient folding operation of the rotary arm 200, which can be more adaptable to application scenarios that require rapid deployment.

[0035] refer to Figure 2In some embodiments, the storage layer 101 is provided with two layers arranged side by side in the height direction, and each storage layer 101 is used to accommodate a drive assembly 500. By providing two storage layers 101, each storage layer 101 accommodates each drive assembly 500. Since the length of the pair of rotary arms 200 is relatively long, the length of the drone is less than the sum of the lengths of the two rotary arms 200. In order to avoid positional interference between the two rotary arms 200 that are opposite to each other in the length direction of the drone after the rotary arms 200 are folded, the drive assemblies 500 that drive the two pairs of rotary arms 200 to be deployed or stored are arranged in different storage layers 101. This can achieve staggered position distribution. Under the premise of meeting the space requirements after folding and storage, the size of the drone can be reduced as much as possible, which is conducive to the miniaturization of the drone and also facilitates the orderly movement of the two drive assemblies 500 without interference.

[0036] refer to Figures 1 to 6 In some embodiments, each rotary arm 200 is rotatably mounted on the body 100; the drive assembly 500 includes a slider 510 slidably mounted within the storage layer 101, and an elastic member (not shown) connecting the body 100 and the slider 510. In other words, each slider 510 connects a pair of rotary arms 200. It is essential that the two sliders 510 slide in opposite directions.

[0037] Specifically, when the elastic member is in its initial state, the pair of arms 200 connected to the slider 510 are in an extended state. When the elastic member is in its extended state, the pair of arms 200 connected to the slider 510 are in a retracted state. With this arrangement, when the slider 510 slides and drives the arms 200 to extend, the elastic member assists in driving the arms 200, making the extension of the arms 200 smoother. Once the arms 200 are extended, the slider 510 stably maintains the extended state.

[0038] refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 In a further embodiment, a first retaining hole 110 is provided vertically through the body 100, and a second retaining hole 511 is provided on each sliding member 510. When each swing arm 200 is in the stowed position, the first retaining hole 110 and each second retaining hole 511 overlap and penetrate each other. By providing the first retaining hole 110 and the second retaining hole 511, the columnar retaining member can penetrate the first retaining hole 110 and the second retaining hole 511 to simultaneously secure both sliding members 510, thereby stably maintaining each swing arm 200 in the stowed position.

[0039] In a further embodiment, a limit member (not shown) is slidably provided on the fuselage 100 in the height direction. The limit member can slide in the first limit hole 110 to be sequentially inserted into the second limit hole 511 provided on each slider 510, or can slide out of the second limit hole 511 on each slider 510 in sequence. When the limit member is completely slid out of the first limit hole 110 and the second limit hole 511, each slider 510 automatically slides under the elastic force of the elastic member to drive each swing arm 200 to deploy. This eliminates the need to manually push each slider 510, and the drone can be deployed faster.

[0040] refer to Figures 1 to 6 In some specific embodiments, in one pair of two rotary arms 200 arranged opposite to each other in the width direction, one end of the rotary arm 200 is rotatably set on the fuselage 100, and the driving assembly 500 further includes a connecting rod 520 connecting the sliding member 510 and the middle part of each rotary arm 200; when the sliding member 510 slides, the two rotary arms 200 are synchronously driven to expand or retract; in another pair of two rotary arms 200 arranged opposite to each other in the width direction, one end of the rotary arm 200 is rotatably set on the sliding member 510 and the middle part of the rotary arm 200 is rotatably set on the fuselage 100, and when the sliding member 510 slides, the two rotary arms 200 are synchronously driven to expand or retract.

[0041] By such an arrangement, the rotation radii of the two rotary arms 200 on one side of the fuselage 100 and opposite to each other in the length direction of the fuselage 100 can be inconsistent. That is, after the two rotary arms 200 are rotated and stored, the rotary arm 200 with a smaller rotation radius can be stored on the inner side and the rotary arm 200 with a larger rotation radius can be stored on the outer side based on the inconsistent rotation radii. That is, the storage positions of the two rotary arms 200 can be staggered with each other, so as to facilitate reducing the length and width of the fuselage 100, thereby realizing the miniaturization of the drone.

[0042] refer to Figures 1 to 6 Based on the above embodiments, in some implementations, the two arms 200 are horizontally bent on opposite sides of the longitudinal direction. Specifically, the bend can be an arc or an angle. By bending the arms 200 horizontally, the bend can serve as a guide when the arms 200 are rotated and stored, making the rotation and storage of the arms 200 more convenient.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
