Description

Technical Field

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

[0002] At present, with the rapid development of communication technology and flight control technology, drones are gradually being widely used in many fields due to their small size and light weight. There are three main types of drones: fixed-wing drones, unmanned helicopters and multi-rotor drones, and multi-rotor drones are the most widely used.

[0003] The wings of existing drones are open, which makes it easy for the wings to collide with the outside when they are stored. The wings of drones are generally thin, so that the wings will break when a collision occurs. Therefore, it is necessary to propose a foldable wing for drones. Utility Model Content

[0004] The purpose of the utility model is to provide a foldable wing for a drone to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable wing for an unmanned aerial vehicle, comprising a body, four support rods are fixedly installed on the outer wall of the body, and a storage groove is opened on the four support rods, and a mounting sleeve is rotatably connected between the groove walls of the four storage grooves through a rotating shaft, and a driving motor is fixedly sleeved on the upper ends of the four mounting sleeves, and a fan blade is fixedly connected to the output ends of the four driving motors through a coupling, and an annular groove is opened on the inner wall of the lower ends of the four mounting sleeves, and a fixing plate is slidably connected in the four annular grooves, and a spring is fixedly connected to the upper surfaces of the four fixing plates, and the upper ends of the four springs are respectively against the groove walls of the four annular grooves, and a positioning rod is fixedly connected to the lower surfaces of the four fixing plates, and a positioning hole is opened at the groove bottom of the four storage grooves corresponding to the position of the positioning rod, and the lower ends of the four positioning rods extend into the four positioning holes respectively.

[0006] Preferably, two receiving holes are formed through the groove walls of the four receiving grooves, and each group of two receiving holes are arranged in parallel.

[0007] Preferably, the four mounting sleeves are rotatably connected between the inner walls of the four receiving grooves on the side away from the machine body through rotating shafts.

[0008] Preferably, the four installation sleeves are all arranged vertically, and the upper ends of the four installation sleeves extend through and outside the receiving groove.

[0009] Preferably, the four receiving grooves respectively match with four mounting sleeves.

[0010] Compared with the prior art, the beneficial effect of the utility model is that when in use, the positioning hole supports the mounting sleeve through the positioning rod, so that the mounting sleeve supports the motor blades and keeps them vertical, thereby facilitating the operation of the wing. By pushing the positioning rod upward, the positioning rod is disengaged from the positioning hole and the limit on the mounting sleeve is released. At this time, the mounting sleeve can be rotated to be laid down in the storage groove. At the same time, the storage hole stores and limits the blades, so that the blades are arranged in a cross shape to prevent their top ends from being lifted up and broken, and the whole is convenient to store.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3The utility model provides a technical solution: a foldable wing for a drone, comprising a body 1, four support rods 2 are fixedly installed on the outer wall of the body 1, and a receiving groove 3 is opened on the four support rods 2, and a mounting sleeve 4 is rotatably connected between the groove walls of the four receiving grooves 3 through a rotating shaft, and a driving motor 5 is fixedly sleeved on the upper ends of the four mounting sleeves 4, and a fan blade 6 is fixedly connected to the output end of the four driving motors 5 through a coupling, and an annular groove 7 is opened on the inner wall of the lower end of the four mounting sleeves 4, and a fixing plate 8 is slidably connected in the four annular grooves 7, and a spring 9 is fixedly connected to the upper surface of the four fixing plates 8, and the upper ends of the four springs 9 are respectively against the groove walls of the four annular grooves 7, and a positioning rod 10 is fixedly connected to the lower surface of the four fixing plates 8, and a positioning hole 11 is opened through the groove bottom of the four receiving grooves 3 corresponding to the position of the positioning rod 10, and the lower ends of the four positioning rods 10 extend through the four positioning holes 11 respectively.

[0017] Among them, two receiving holes 12 are formed through the groove walls of the four receiving grooves 3, and each group of two receiving holes 12 are arranged in parallel, so that the fan blades 6 can be stored and limited through the receiving holes 12.

[0018] The four installation sleeves 4 are rotatably connected between the inner walls of the four receiving slots 3 on the side away from the body 1 through the rotating shafts, so that the installation sleeves 4 rotate based on the rotating shafts.

[0019] Among them, the four installation sleeves 4 are all arranged vertically, and the upper ends of the four installation sleeves 4 extend through the storage groove 3, so that the installation sleeves 4 support the driving motor 5 and the fan blades 6 and maintain a vertical state to facilitate their operation.

[0020] The four receiving grooves 3 are respectively matched with the four installation sleeves 4 , so that the installation sleeves 4 can lie in the receiving grooves 3 .

[0021] Specifically, when using the utility model, the positioning hole 11 limits the positioning rod 10 to keep it vertical, and the positioning rod 10 and the rotating shaft support the mounting sleeve 4 to keep it vertical, and the drive motor 5 and the fan blades 6 are kept in a vertical state under the support of the mounting sleeve 4 to facilitate their operation.
