Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of folding unmanned aerial vehicles (UAVs), and in particular to a foldable UAV. Background Art
[0002] There are many types of intelligent simulation toys at present, but the simulation and control performance are relatively poor, and the experience is poor. In order to meet consumers' demand for various intelligent toy simulation experiences, drone toys are developed. Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by an onboard computer. Multi-rotor UAVs are unmanned aircraft with multiple arms, powered by motors on the arms, which generate physiological signals. The arms are radially positioned relative to the fuselage, which at least doubles the space occupied by the drone. When the drone arms are unfolded, they occupy a large space, increasing transportation costs and making them prone to collisions, which reduces the lifespan of the drone. The current foldable method for drone arms is to fold the four arms toward the middle of the fuselage of the frame, which can effectively utilize space. However, the arms fold toward the middle of the fuselage, and the blades mounted on the arms cannot be too large, resulting in low efficiency of the drone and limited flight time, which is also the difficulty of folding technology. In addition, the battery cannot be quickly disassembled and assembled. Furthermore, the camera cannot rotate, and the probe can only monitor a certain area.
[0003] In order to address the above problems, a foldable drone is urgently needed. Utility Model Content
[0004] The purpose of the present invention is to provide a foldable drone to solve the problems raised in the above background technology.

[0006] A groove is provided on the side wall of the drone body, and a rotatable landing gear is installed in the groove via a latch. The landing gear is in an L-shaped structure. When retracted, the landing gear is inverted on the drone body and retracted into the groove;
[0007] The folding arm is entirely located on the top of the drone body in the folded state, and in the unfolded state, the folding arm is perpendicular to the top of the drone body.
[0008] Furthermore, the mounting groove is a cylindrical structure, the bottom of which is a hemispherical structure, and an opening is provided on its side for connecting the folding arm.
[0009] Furthermore, the folding mechanism includes a ball sleeve arranged at the bottom of the installation groove, a spherical hollow area is provided inside the ball sleeve, a track groove is opened on its surface, the track groove is connected to the hollow area inside the ball sleeve, and an axial ball is installed in the hollow area.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] Those skilled in the art will understand that, unless otherwise stated, the singular forms "a," "an," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present utility model refers to the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.
[0023] See also Figure 1-3 As shown, a foldable drone is provided, comprising a drone body 1, the drone body 1 being a cylindrical structure, a mounting slot 2 being formed on the top of the drone body 1, a folding arm 4 being connected to the mounting slot 2 via a folding mechanism 3, the distal end of the folding arm 4 being bent upward to form a protective rod, a flight motor 5 and propellers 6 being mounted on the folding arm 4, wherein the maximum folding angle of the folding mechanism 3 is 90°;
[0024] A groove 7 is provided on the side wall of the drone body 1, and a rotatable landing gear 9 is installed in the groove 7 via a latch 8. The landing gear 9 is in an "L"-shaped structure. When folded, the landing gear 9 is buckled onto the drone body 1 and retracted into the groove 7. It is worth noting that the "L"-shaped landing gear 9 can be buckled onto the surface of the drone body 1 when folded, so as to achieve a tight and secure fixation effect. In the unfolded state, the shorter end becomes a contact foot that increases contact with the ground, thereby achieving a better support effect and ensuring that the drone can be docked more stably when landing.
[0025] The folding arm 4 is entirely located on the top of the drone body 1 in the folded state, and in the unfolded state, the folding arm 4 is perpendicular to the top of the drone body 1.
[0026] It is worth noting that the mounting groove 2 is a cylindrical structure with a hemispherical bottom and an opening on its side. The opening is used to connect the folding arm 4 to achieve a 90° folding effect of the folding arm 4. Therefore, the mounting groove 2 here needs to be set close to the edge of the drone body 1; at the same time, in order to ensure the stability of the drone during flight, the mounting groove 2 needs to be set symmetrically;
[0027] The folding mechanism 3 includes a ball sleeve 301 disposed at the bottom of the mounting groove 2. The ball sleeve 301 has a spherical hollow area inside and a track groove 302 on its surface. The track groove 302 is connected to the hollow area inside the ball sleeve 301. A shaft ball 303 is installed in the hollow area.
[0028] The end of the folding arm 4 is provided with a connecting frame 10, the other end of the connecting frame 10 passes through the track groove 302 and is fixedly connected to the shaft ball 303 in the hollow area (that is, the connecting frame 10 is installed in the track groove 302, and the two ends of the connecting frame 10 are respectively connected to the shaft ball 303 and the folding arm 4), and the connecting frame 10 can rotate in the track groove 302 through the shaft ball 303;
[0029] On the basis of the above embodiment, dampers are provided at both ends of the latch pin 8, and protrusions are provided on the side walls of the track groove 302. The function of the dampers and protrusions here is to increase the friction resistance so that the connecting frame 10 or the landing gear 10 can be fixed more firmly at a certain point without the action of external force, and the angle folding effect can be easily achieved under manual bending.
[0030] In order to achieve better effect and practicality, the groove 7 and the landing gear 9 are arranged in a ring shape, and the number of the folding arms 4 is not less than four; a camera 11 is also installed on the side wall of the drone body 1, and the camera 11 is specifically a spherical camera, wherein the spherical camera can be rotated at multiple angles including but not limited to up, down, left and right;
[0031] At the same time, for better carrying and protection, the drone body 1 in the folded state can be stored entirely in a separate cylinder.
[0032] Working principle:
[0033] The drone can be deployed in an unfolded state for use and folded state for storage. The following is the transition process between the unfolded and folded states:
[0034] In the unfolded state, the folding arms 4 are folded upward along the direction of the track groove 302 so that the folding arms 4 are perpendicular to the top of the drone body 1. Similarly, the landing gears 9 are folded upward 180 degrees along the direction of their respective grooves 7 so that the landing gears 9 can be buckled on the top of the drone body 1. At this time, the drone is Figure 1 The state shown changes to Figure 2 Status shown;
[0035] In the folded state, the folding arms 4 are folded downward along the direction of the track groove 302 so that the folding arms 4 are parallel to the top of the drone body 1; similarly, the landing gears 9 are folded downward 180 degrees along the direction of their respective grooves 7 so that the landing gears 9 are at the bottom of the drone body 1. At this time, the drone is Figure 2 The state shown changes to Figure 1 Status shown.
[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
