Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles, in particular to a foldable unmanned aerial vehicle. Background Art

[0002] In the context of the rapid development of modern science and technology, drones have become an important tool in the fields of military reconnaissance, geographic mapping, disaster monitoring and consumer photography. However, with the continuous expansion of the scope of application, the portability and ease of operation of drones have also received more and more attention. Especially for users who often need to use drones in different locations, the inconvenience of carrying and transporting traditional drones has become a prominent problem. Traditional drone designs usually focus on performance and stability, but pay less attention to volume and weight. Most drones use a fixed fuselage structure, which means that they still occupy a large space when not in use, especially drones with four axes and above. This structure limits the deployment speed of drones in small or complex environments, and also brings inconvenience to cross-regional transportation. Because the fuselage and wings of drones cannot be folded flexibly, they are difficult to arrange neatly and compactly during loading and transportation, and are prone to collision and damage. This not only increases logistics costs, but also affects the service life and reliability of drones. Traditional drones with foldable arms need to fold the arms one by one when folding, which is inefficient and time-consuming. Utility Model Content

[0003] The purpose of the utility model is to provide a foldable drone to solve the problems of low efficiency and safety risks caused by large size and complicated operation of traditional drones in the process of carrying and transporting.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A foldable drone comprises a drone body, wherein the drone body comprises a first cover plate and a second cover plate, an arm assembly is arranged between the first cover plate and the second cover plate, the arm assembly comprises a plurality of arms, each of the arms is provided with a rack meshing portion, each of the arms in the arm assembly meshes with each other through the rack meshing portion, and the arm assembly is configured such that: by moving any one of the arms, the remaining arms can move through the cooperation of the rack meshing portions, thereby realizing the opening and closing of the arm assembly.

[0006] The utility model is a foldable drone, and a rack meshing part is integrated on the arm of the drone. This design connects all the arms into a unified arm assembly through the rack meshing part, realizing a synchronous control mechanism, that is, operating any arm can drive the remaining arms to be synchronously unfolded or folded. In addition, the fuselage of the drone is designed to be able to clamp the arm assembly, so that the arms can be folded when not in use, which significantly reduces the overall volume of the drone, thereby improving the transportation efficiency and safety of the drone. During transportation, the folded drones can be arranged more compactly, significantly reducing the gaps between drones, and effectively preventing collisions and damage caused by vibration or shaking during transportation. In addition, this design simplifies the preparations before transportation, and the user only needs to operate one arm to quickly complete the unfolding or folding of the drone, thereby improving the speed and efficiency of the operation.

[0007] As a preferred embodiment of the utility model, a connecting portion is provided on the arm, the connecting portion includes a second connecting hole, the rack meshing portion is arranged outside the second connecting hole, and the rack meshing portion is gear-shaped. The rack meshing portion is arranged in a gear shape to facilitate the meshing and connection between the arms.

[0008] As a preferred solution of the utility model, a plurality of first connecting holes are provided on the first cover plate, a second connecting hole is provided on the connecting part, a third connecting hole is provided on the second cover plate, and the size and position of the second connecting holes are adapted to the first connecting holes and the third connecting holes. Such an arrangement makes the structure of the drone more stable.

[0009] As a preferred solution of the utility model, the first connecting hole, the second connecting hole and the third connecting hole are all fixed by the same screw, and the screw passes through the first connecting hole, the second connecting hole and the third connecting hole in sequence, ensuring the stability of the connection between the entire drone fuselage and the arm.

[0010] As a preferred solution of the utility model, a mounting hole is provided on the arm, an elastic buckle is provided in the mounting hole, an elastic structure is provided between the elastic buckle and the mounting hole, a first limiting hole is provided on the first cover plate, a second limiting hole is provided on one side of the first limiting hole, the first limiting hole and the second limiting hole are located at different positions on the same plane, and the first limiting hole and the second limiting hole are both adapted to the elastic buckle. This arrangement enables the arm to be limited by the first limiting hole or the second limiting hole when unfolding and closing, thereby preventing the arm from being displaced.

[0011] As a preferred solution of the utility model, a limit block is provided between two adjacent arms, and the limit block is configured as follows: when the arm assembly is closed, the shape and size of the limit block are adapted to the gap between the two adjacent arms. This arrangement enables the drone arms to be limited by the limit block when folded, thereby avoiding collision between adjacent arms.

[0012] As a preferred solution of the utility model, the first limiting hole and the second limiting hole have the same size, and the first limiting hole and the second limiting hole are both arranged on the trajectory line of the elastic buckle. This arrangement ensures that the elastic buckle can always be connected with the first limiting hole or the second limiting hole.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. The utility model is a foldable drone, and a rack meshing part is integrated on the arm of the drone. This design connects all the arms into a unified arm assembly through the rack meshing part, realizing a synchronous control mechanism, that is, operating any arm can drive the remaining arms to be synchronously unfolded or folded. In addition, the fuselage of the drone is designed to be able to clamp the arm assembly, so that the arm can be folded when not in use, which significantly reduces the overall volume of the drone, thereby improving the transportation efficiency and safety of the drone. During transportation, the folded drones can be arranged more compactly, significantly reducing the gaps between drones, and effectively preventing collisions and damage caused by vibration or shaking during transportation. In addition, this design simplifies the preparations before transportation, and the user only needs to operate one arm to quickly complete the unfolding or folding of the drone, thereby improving the speed and efficiency of the operation.

DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Example 1

[0027] like Figure 1-5 A foldable drone is shown, the drone comprises a drone body, the drone body is formed by splicing a first cover plate 1 and a second cover plate 2, an arm assembly 3 is provided between the first cover plate 1 and the second cover plate 2, the arm assembly 3 comprises a plurality of arms 31 of the same shape, each arm 31 is provided with a rack meshing portion 32, and each arm 31 meshes with an adjacent arm 31 through its own rack meshing portion 32;

[0028] Furthermore, meshing teeth are provided on the rack meshing portion 32, so that each rack meshing portion 32 can mesh with each other through the meshing teeth. The operator only needs to control the movement of one of the arms 31 to realize the opening and closing of the arm assembly 3, so that the drone can be folded. The folded drone occupies less space and is easy to transport.

[0029] As mentioned above, the arm 31 is provided with a connecting portion 311, and the connecting portion 311 is provided with a second connecting hole 312, and the second connecting hole 312 is used to subsequently realize the connection between the arm 31 and the first cover plate 1 and the second cover plate 2, and the connecting portion 311 also includes a rack engagement portion 32, and the rack engagement portion 32 is arranged on the periphery of the second connecting hole 312;

[0030] Furthermore, a first connection hole 13 is provided on the first cover plate 1, and a third connection hole 21 is provided on the second cover plate 2. The first connection hole 13 and the third connection hole 21 are set to be the same size and the same position on the vertical line as the second connection hole 312 on the machine arm 31;

[0031] Furthermore, the first cover plate 1 is connected to the second cover plate 2 and the arm 31 by screws, and the screws pass through the first connection hole 13, the second connection hole 312 and the third connection hole 21 in sequence, so as to ensure that the first cover plate 1, the second cover plate 2 and the arm 31 can be connected as a whole;

[0032] Optionally, the screw is a toothed screw, which can connect the first cover plate 1, the second cover plate 2 and the machine arm 31 as a whole, and can also facilitate the rotation of the machine arm 31. Figure 5-8 shown.

[0033] As mentioned above, the arm 31 is provided with a mounting hole 313, and an elastic buckle 5 is provided in the mounting hole 313. The elastic buckle 5 can reciprocate along the axial direction of the mounting hole 313 after being subjected to force, and the first cover plate 1 is provided with a first limiting hole 11 and a second limiting hole 12, and the first limiting hole 11 and the second limiting hole 12 are both adapted to the elastic buckle 5. Since the elastic buckle 5 is arranged on the arm 31, and the rotation of the arm 31 is based on the axis of the second connecting hole 312, the moving path of the elastic buckle 5 when the arm 31 rotates is an arc, and the first limiting hole 11 and the second limiting hole 12 are both arranged on the arc.

[0034] Furthermore, when the drone arm 31 is in a closed state, the elastic buckle 5 is engaged with the first limiting hole 11. When it is necessary to unfold the drone arm 31, the elastic buckle 5 is pushed, and the elastic buckle 5 is pressed downward, causing the entire elastic buckle 5 to retract. When the elastic buckle 5 rotates to the second limiting hole 12, the elastic buckle 5 rebounds and engages with the second limiting hole 12, completing the unfolding of the drone arm 31. Figure 6 shown.

[0035] As mentioned above, a limit block 6 is provided between two adjacent arms 31, and the limit block 6 is configured as follows: when the arm assembly 3 is closed, the shape and size of the limit block 6 are adapted to the gap between the two adjacent arms 31. This configuration enables the drone arms 31 to be limited by the limit block 6 when folded, thereby avoiding collision between adjacent arms 31. Figure 4 shown.

[0036] As mentioned above, the first limiting hole 11 and the second limiting hole 12 have the same size, and the first limiting hole 11 and the second limiting hole 12 are both arranged on the trajectory line of the elastic clip 5. This arrangement ensures that the elastic clip 5 can always be connected with the first limiting hole 11 or the second limiting hole 12.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
