[0034] First embodiment

[0035] Reference Figure 1 , Figure 2 , Figure 1 A three-dimensional schematic diagram of a folding device according to an embodiment of the present invention is shown. Figure 2 Shows Figure 1 The exploded schematic diagram of the folding device is shown in FIG. 1 , wherein the folding device includes a base 100, a rotating member 200, a locking member 300 and a first elastic member 400, wherein a groove 101 is provided on the base 100, the rotating member 200 is rotatably connected to the base 100 via a rotating shaft 210, the locking member 300 is connected to the rotating member 200, can rotate synchronously with the rotating member 200 to achieve folding, and can move relative to the rotating member 200 until inserted into the groove 101, thereby locking the rotating member 200, and the first elastic member 400 can drive the rotating member 200 to rotate and reset after the locking member 300 is disengaged from the groove 101.

[0036] The base 100 is used as a supporting structure, and a structure for rotationally connecting with the rotating member 200 is provided thereon, for example Figure 1 The rotating member 200 and the base 100 can be connected by using a known technique, for example, Figure 1 The side plate 110 is provided with a shaft hole, and the two ends of the shaft 210 are connected from the opposite sides of the rotating member 200 (for example Figure 1 The rotating shaft 210 extends out from the base 100 and is inserted into the rotating shaft holes on the two side plates 110. The rotating shaft 210 may be fixed to the base 100 and rotatably connected to the rotating member 200, or the rotating shaft 210 may be fixed to the rotating member 200 and rotatably connected to the base 100, or the rotating shaft 210 may be rotatably connected to the base 100 and the rotating member 200 respectively.

[0037] The lower part of the rotating member 200 is provided with a first through hole 220 for mounting the rotating shaft 210. The first through hole 220 penetrates the rotating member 200 and is provided at opposite sides of the rotating member 200 (for example, Figure 1 The rotating shaft 210 is inserted into the first through hole 220, and both ends extend out of the first through hole 220. In other embodiments, the rotating shaft 210 can also be integrally connected to the rotating member 200. The rotating member 200 is also provided with a second through hole 230 for mounting the locking member 300. The second through hole 230 penetrates the rotating member 200 and is provided on opposite sides of the rotating member 200 (for example, Figure 1The locking member 300 of the present embodiment may be a slender rod, and the locking member 300 is inserted into the second through hole 230 in a clearance fit or transition fit manner, so that the locking member 300 can slide in the second through hole 230. The upper end of the locking member 300 can extend upward from the second through hole 230, and the lower end can extend downward from the second through hole 230 after the locking member 300 slides downward a set distance. In other embodiments, the locking member 300 may also be of other shapes, as long as it is ensured that it has an end that can extend from the rotating member 200 and can be plugged into and fit with the groove 101. The connection method between the locking member 300 and the rotating member 200 is not limited to the above, and any structure that enables the locking member 300 to rotate synchronously with the rotating member 200 and slide independently relative to the rotating member 200 is acceptable.

[0038] The first elastic member 400 in this embodiment is used to drive the rotating member 200 to rotate and reset, and it can be a torsion spring or a spring. In this embodiment, the rotating member 200 is installed in the installation cavity of the base 100, and there is a gap between the rotating member 200 and the left and right side plates 110 of the base 100, and the gap is used to place two first elastic members 400, or the two ends of the same first elastic member 400. The first elastic member 400 is respectively arranged on the left and right sides of the rotating member 200 or the two ends of the same first elastic member 400, so that the force on the rotating member 200 is more balanced. The connection structure of the first elastic member 400 and the rotating member 200 can adopt a known technology, which will not be described in detail here.

[0039] The method of using this embodiment is as follows: when the rotating member 200 is rotated relative to the base 100 until the locking member 300 is aligned with the groove 101 (for example Figure 1 In the state shown, the locking member 300 is Figure 1 101), at this time, the rotating member 200 and the locking member 300 are in the working state, the lower end of the locking member 300 is inserted into the groove 101, limiting the rotation of the rotating member 200, and the first elastic member 400 is compressed. When the locking member 300 is separated from the groove 101 by an external force (for example, the operator pulls out the locking member 300), the rotating member 200 is driven by the first elastic member 400 to rotate at a set angle (for example, 90°, that is, the locking member 300 moves to the left). Figure 1 The rotating member 200 and the locking member 300 are in the folded state. The functional member that needs to protrude during operation can be installed on the rotating member 200 or the locking member 300 to achieve the folding of the functional member. This embodiment has a relatively simple structure and low cost. It can switch between the folded state and the locked state through simple operations, and is easy to use.

[0040] Second embodiment

[0041] This embodiment is an improvement on the first embodiment. In this embodiment, referring to Figure 1 , Figure 3 , the first through hole 220 is connected to the second through hole 230, and together form a "cross-shaped" channel. Figure 2 , Figure 4 The locking member 300 of this embodiment is provided with a locking member 300 along the moving direction of the locking member 300 (for example Figure 3 During installation, the rotating shaft 210 passes through the first through hole 220 and the strip hole 310, and after the locking member 300 moves up or down by a set distance, it will abut against the rotating shaft 210 and cannot move further. That is, this embodiment uses the existing rotating shaft 210 to limit the locking member 300, and the locking member 300 does not need to be provided with an additional limiting structure, which helps to simplify the structure.

[0042] Third embodiment

[0043] This embodiment is an improvement on the first embodiment. In this embodiment, referring to Figures 2 to 4 The locking member 300 is limited by other structures. Specifically, the locking member 300 is provided with a resisting portion 320. The resisting portion 320 is arranged on the locking member 300 relative to the rotating member 200 in the direction of disengaging from the groove 101 (for example Figure 1 The locking member 300 is moved in the upward direction (in the middle) for a set distance to abut against the rotating member 200, thereby limiting the further movement of the locking member 300 (the downward movement of the locking member 300 can be limited by abutting against the base 100). The abutting portion 320 of this embodiment is an enlarged portion located at the bottom of the locking member 300. In this embodiment, the locking member 300 is not limited by the rotating shaft 210, so there is no need to set a bar hole on the locking member 300.

[0044] Fourth embodiment

[0045] This embodiment is an improvement on the first embodiment. In this embodiment, referring to Figure 2 , Figure 3 , further comprising a second elastic member 500. The second elastic member 500 of this embodiment may be a spring, which is sleeved on the locking member 300, with one end abutting against the locking member 300 and the other end abutting against the rotating member 200. The second elastic member 500 can, on the one hand, drive the locking member 300 to be inserted into the groove 101 when the locking member 300 is rotated to align with the groove 101, and on the other hand, can also prevent the locking member 300 from being easily disengaged after being inserted into the groove 101.

[0046] Fifth embodiment

[0047] This embodiment is an improvement on the first embodiment. In this embodiment, referring to Figure 1 , Figure 3The locking member 300 has an inserting cavity 330 disposed therein, and the locking member 300 is located at one end (eg Figure 1 An insertion interface connected to the insertion cavity 330 is provided on the upper end of the folding device, that is, the present embodiment can utilize the existing locking member 300 to install the functional member, and the functional member does not need to be connected to the folding device through an additional structure, which helps to simplify the structure.

[0048] Sixth embodiment

[0049] This embodiment is an improvement on the first embodiment. In this embodiment, referring to Figure 1 , the top and one side (eg Figure 1 The front side of the folding device is open, that is, the top of the base 100 is provided with a first opening connected to the installation cavity, and the front side is provided with a second opening connected to the installation cavity, and the first opening and the second opening are connected to each other. Correspondingly, the rotation angle of the rotating member 200 is 90°, the locking member 300 can extend to the outside of the folding device through the first opening or the second opening, and the locking member 300 can rotate between the first opening and the second opening. Specifically, the base 100 in this embodiment includes three side panels 110 and a bottom plate 120, and the three side panels 110 are sequentially distributed along the circumference of the bottom plate 120 (for example, connected in sequence). Figure 1 The left side, rear side and right side of the bottom plate 120) define the above-mentioned installation cavity together with the bottom plate 120. In this way, the locking member 300 can be rotated within a set range to prevent the locking member 300 from rotating to other inappropriate positions, thereby realizing anti-mistaken rotation of the locking member 300.

[0050] Seventh embodiment

[0051] This embodiment discloses a drone, including the folding device of each of the above embodiments, and a functional part, which forms a protruding structure when in use, such as an antenna. The functional part of this embodiment is connected to the locking member 300, and the rotation of the locking member 300 is used to achieve the switching between the folding state and the use state. Taking the antenna as an example, a folding groove can be set on the surface of the drone body, and the folding device is installed in the folding groove. When the antenna needs to be used, the locking member 300 is in a position such as Figure 1 When the antenna needs to be folded for transportation and storage, the locking member 300 can be moved from, for example, Figure 1 The state shown is a state of rotating 90° to the front side, at which time the antenna is hidden in the folding groove, so that the antenna is folded. In other embodiments, the functional part can also be connected to the rotating part 200.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
