Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with foldable arms. Background Technology

[0002] A drone is an unmanned aerial vehicle. It typically consists of an airframe, power system, control system, communication system, and various sensors and onboard equipment. Drones can perform missions through pre-programmed procedures, ground remote control, or autonomous flight algorithms. Their applications are wide-ranging, covering military reconnaissance, aerial photography and mapping, agricultural plant protection, logistics delivery, disaster relief, and many other areas. In the military, drones can perform dangerous reconnaissance and attack missions, reducing casualties; in the civilian sector, they provide people with efficient, convenient, and unique perspectives and solutions. With their flexibility, efficiency, and relatively low cost, drones are gradually changing the way we live and work.

[0003] Existing drones still have some drawbacks. First, the blades of most drones on the market cannot be folded and stored. This means that if the drone is accidentally bumped and falls to the ground when not in use, the blades are easily damaged, affecting its use. Utility Model Content

[0021] like Figures 1-6 As shown, this utility model provides a technical solution: a drone with a foldable arm, including a folding mechanism 5 on the body 1, a support seat 2 on the top of the folding mechanism 5, a motor 3 fixedly installed on the top of the support seat 2, a blade 4 fixedly connected to the output end of the motor 3, and a protective mechanism 6 on the body 1.

[0022] The aforementioned folding mechanism 5 includes: a first slide groove 501, a slider 502, a short rod 503, a first long rod 504, a protrusion 505, and a C-shaped slider 506. The first slide groove 501 is located on the top of the body 1. The first slide groove 501 has two sets of slides symmetrically arranged about the vertical centerline of the body 1. The slider 502 is slidably connected inside the first slide groove 501. The top of the slider 502 is hinged to the short rod 503, and the bottom of the short rod 503 is hinged to the first long rod 504. A long rod 504 is provided, with its end point hinged to the side wall of a C-shaped slider 506. The C-shaped slider 506 can drive the long rod 504 to slide back and forth. One end of a short rod 503 is hinged to the top of a slider 502, and the other end of the short rod 503 is fixedly connected to the top of the long rod 504. A bearing seat 2 is fixedly installed on the top of the short rod 503. A protrusion 505 is fixedly installed on the top of the body 1, and a C-shaped slider 506 is slidably installed on the top of the protrusion 505.

[0023] The aforementioned protective mechanism 6 includes: a round rod 601, a second long rod 602, a fixing block 603, a second sliding groove 604, a sliding rod 605, and a protective cover 606. The round rod 601 is fixedly installed on the side wall of the C-shaped slider 506. The top of the round rod 601 is hinged to the second long rod 602. The bottom of one end of the second long rod 602 is hinged to the top of the round rod 601, and the top of the other end of the second long rod 602 is hinged to the bottom of the fixing block 603. The bottom of the machine body 1 is provided with a second sliding groove 604. The sliding rod 605 is slidably connected inside the second sliding groove 604. The protective cover 606 is fixedly installed on the side wall of the sliding rod 605. The fixing block 603 is fixedly installed on the inner wall of the protective cover 606. Two sets of protective covers 606 are provided, and the two sets of protective covers 606 are respectively located on both sides of the machine body 1. The top of the second long rod 602 is hinged to the fixing block 603. The protective cover 606 can play a role in dust prevention and can also prevent unnecessary collisions from damaging its internal parts.

[0024] Working principle: By pulling the C-shaped slider 506 backward, the first long rod 504 connected to it slides backward, causing the short rod 503 to move inward. At this time, the slider 502 connected to it will move inward in the first slide groove 501. At this time, the motor 3 and blade 4 installed on the support seat 2 of the short rod 503 rotate inward together with the short rod 503. Pulling the C-shaped slider 506 will also pull the second long rod 602 inward. Due to the pulling force, the slide rod 605 will slide in the second slide groove 604 and move towards the machine body 1. At the same time, the protective cover 606 connected to the slide rod 605 will also move towards the machine body 1, achieving the protective effect.

[0025] When deployment is required, the first long rod 504 in the retracted state is roughly close together. At this time, pushing the C-shaped slider 506 causes the first long rod 504 to push the slider 502 connected to the short rod 503 to slide outward from the first slide groove 501. At this time, the motor 3 and blade 4 mounted on the support 2 of the short rod 503 will unfold outward along with the short rod 503. While pushing the C-shaped slider 506, the second long rod 602 will also unfold to both sides. Under the action of thrust, the slide rod 605 will slide outward from the second slide groove 604, causing the protective cover 606 to open. After the deployment is completed, it can take off. It should be noted that the protective cover 606 will not interfere with the rotation of the blade 4.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
