[0039] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0040] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0042] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] like Figures 1-6As shown, a foldable drone according to an embodiment of the present disclosure includes a fuselage 1 and mounting arms 2. Multiple mounting arms 2 are mounted on the fuselage 1. The drone also includes a transmission rod 3, a foldable wing 4, a positioning ring 5, an abutment positioning mechanism, a mounting cover 6, and a locking mechanism. Compared with the prior art, in this embodiment, by setting the transmission rod 3, the foldable wing 4 can be folded and stored, reducing the overall size of the drone and making it easier for users to carry. Through the cooperation of the abutment positioning mechanism and the locking mechanism, the foldable wing 4 is abutted and positioned on the mounting arms 2 after being unfolded or folded, ensuring the stability of the foldable wing 4 after being unfolded or folded.

[0046] like Figures 2-4 As shown, the transmission rod 3 is rotatably mounted on the mounting arm 2. A foldable wing 4 is sleeved on the transmission rod 3. A receiving groove is provided on the outside of the mounting arm 2. The height of the receiving groove is adapted to the height of the foldable wing 4. The rotation of the transmission rod 3 can drive the foldable wing 4 to fold to the inside of the mounting arm 2, which can realize the rapid unfolding or folding of the foldable wing 4, making it convenient for users to carry the drone.

[0047] like Figure 4 and Figure 5 As shown, multiple positioning rings 5 ​​are installed on the lower side of the fuselage 1 via a mounting plate. The abutting positioning mechanism is sleeved on the transmission rod 3. The abutting positioning mechanism includes a mounting bracket 101, an abutting positioning seat 102, and a snap-fit ​​plate 103. A square groove is installed on the transmission rod 3. A square groove is opened on the inner side of the mounting bracket 101. The mounting bracket 101 can move along the square bar through the square groove. An anti-slip pad is provided on the upper side of the abutting positioning seat 102. When the abutting positioning mechanism moves upward, it can abut against the positioning rings 5, thereby realizing the positioning of the foldable wing 4 after unfolding or folding, ensuring the overall stability of the UAV.

[0048] like Figure 5 As shown, the mounting cover 6 is sleeved on the transmission rod 3. A movable opening is provided on the outer side of the mounting cover 6. An adjusting component is installed on the outer side of the mounting bracket 101. The width of the movable opening matches the width of the adjusting component. When the adjusting component drives the abutment positioning mechanism to move vertically, the adjusting component moves inside the movable opening. A locking mechanism is provided on the outer side of the mounting cover 6, such as... Figure 6As shown, the locking mechanism includes a housing 201, an adjusting rod 202, a sliding plate 203, a locking block 204, and a spring 205. A slide rail is installed inside the housing 201, and the sliding plate 203 is slidably connected to the slide rail. A limit baffle is installed on the inner side of the slide rail, and a buffer layer is provided inside the limit baffle. When the sliding plate 203 moves, it will slide along the slide rail. The slide rail limits the sliding of the sliding plate 203, and the limit baffle blocks and limits the sliding of the sliding plate 203. When the abutment positioning mechanism moves upward, the locking plate 103 can be inserted into the locking mechanism. The locking mechanism locks and positions the locking plate 103, thereby achieving positioning after the abutment positioning mechanism abuts.

[0049] Working principle: When the drone needs to be folded, the user pulls the sliding plate 203 outward along the slide rail using the adjusting rod 202. The sliding plate 203 compresses the spring 205, and the sliding plate 203 drives the locking block 204 to move outward, canceling the locking mechanism's locking position on the locking plate 103. Then, the user pushes the mounting bracket 101 downward along the square bar using the adjusting component. The mounting bracket 101 drives the abutment positioning seat 102 downward through the upright, canceling the abutment positioning mechanism's positioning on the transmission rod 3. After cancellation, the user... The foldable wing 4 is deflected around the transmission rod 3, causing it to fold into the mounting arm 2, thus folding the drone. After folding, the user pushes the abutment positioning mechanism upward to abut against the positioning ring 5 through the adjustment component. After abutment, the user releases the adjustment rod 202, and the sliding plate 203, under the action of the spring 205, drives the locking block 204 to lock into the inside of the locking plate 103, realizing the positioning of the abutment positioning mechanism after abutment. This allows the abutment positioning mechanism to position the transmission rod 3, ensuring the stability of the foldable wing 4 after folding.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
