Description

Technical Field

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

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by onboard computers, either completely or intermittently. Due to their low production and operating costs, as well as their flexibility, stability, light weight, unrestricted takeoff and landing, and ability to hover in the air, they are now widely used in various fields.

[0003] However, existing drones cannot achieve automatic leveling during takeoff. If a drone is placed on an incline for takeoff, the lift generated by the fan blades will cause it to tilt, making it unable to take off vertically. This can easily cause the drone to lose balance and fall to the ground, resulting in takeoff failure. Furthermore, existing drones cannot automatically adjust their landing angle during descent. When a drone lands on an incline, it will tilt along with the incline, which can easily cause the drone to tip over and be damaged.

[0004] To address these issues, we provide a drone base support structure. Utility Model Content

[0005] 1) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the existing technology and provide a drone base support structure.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drone base support structure, including a drone, a base plate at the lower end of the drone, a balancer at the lower end of the base plate, a horizontal mechanism inside the balancer, a vertical mechanism inside the balancer, support feet at the lower end of the base plate, and a rangefinder at the lower end of the balancer.

[0008] Furthermore, an analyzer is provided inside the balancer, a connecting block is fixedly connected inside the balancer, and a connecting rod is provided inside the connecting block.

[0009] Furthermore, the transverse horizontal mechanism has the same structure as the longitudinal horizontal mechanism. The transverse horizontal mechanism includes a horizontal rod, the center of which is rotated within the connecting block, and the two ends of the horizontal rod have the same weight.

[0010] Furthermore, contact heads are fixedly connected to both ends of the horizontal bar, and the transverse horizontal mechanism includes a contact plate, which is fixedly connected to the lower end of the balancer. The contact plate is arc-shaped and slidably connected to the contact head.

[0011] Furthermore, a balance contact point is provided at the center end of the contact plate. The contact plate is bounded by the balance contact point, with the upper end of the balance contact point being designated as the upper contact point and the lower end as the lower contact point. The contact plate is connected to the analyzer via a wire.

[0012] Furthermore, the support foot includes a telescopic cylinder, which is fixedly connected to the lower end of the base plate. A receiving block is provided at the lower end of the telescopic cylinder, and a moving rod is movably connected to the lower end of the telescopic cylinder.

[0013] Furthermore, a spring is fixedly connected inside the moving rod, the spring is fixedly connected to the lower end of the telescopic cylinder, and a pressing block is fixedly connected inside the moving rod.

[0014] Furthermore, a ball is fixedly connected to the lower end of the moving rod, a foot plate is provided at the lower end of the moving rod, a spherical shell is provided at the upper end of the foot plate, the ball is slidably connected inside the spherical shell, and an anti-slip groove is provided at the lower end of the foot plate. Beneficial effects

[0015] Compared with existing technologies, this drone base support structure has the following advantages: This invention, by incorporating a balancer, can keep the drone body level during takeoff and enable the drone to take off vertically on an incline. This solves the problem that existing drones cannot automatically level themselves during takeoff, which can easily cause the drone to lose balance and fall to the ground, resulting in takeoff failure.

[0016] This invention features four independent support feet that remain constant once each foot contacts the ground, ensuring a horizontal landing for the drone. This solves the problem of existing drones failing to automatically adjust their landing angle, causing them to tilt and potentially tip over when landing on an incline, leading to damage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5 As shown, this utility model provides a technical solution: a drone base support structure, including a drone 1, a base plate 2 at the lower end of the drone 1, a balancer 3 at the lower end of the base plate 2, a horizontal leveling mechanism 4 and a vertical leveling mechanism 5 inside the balancer 3, the horizontal leveling mechanism 4 and the vertical leveling mechanism 5 cooperate to detect whether the drone 1 is currently in a horizontal state, and a rangefinder 7 at the lower end of the balancer 3, the rangefinder 7 is a laser rangefinder, which shines a laser downward to measure the distance between the drone 1 and the ground.

[0021] A connecting block 302 is fixedly connected inside the balancer 3. A connecting rod is provided inside the connecting block 302. The transverse horizontal mechanism 4 has the same structure as the longitudinal horizontal mechanism 5. Taking the transverse horizontal mechanism 4 as an example: the transverse horizontal mechanism 4 includes a horizontal rod 401. The center of the horizontal rod 401 is rotated to the outer end of the connecting rod of the connecting block 302, and it can rotate around the connecting rod at a certain angle. The two ends of the horizontal rod 401 have the same weight, so that the horizontal rod 401 can be kept in a horizontal state. Contact heads 402 are fixedly connected to both ends of the horizontal rod 401. The transverse horizontal mechanism 4 includes a contact plate 403. The contact plate 403 is fixedly connected to the lower end inside the balancer 3. The contact plate 403 is arc-shaped and slidably connected to the contact head 402. An analyzer 301 is provided inside the balancer 3. The contact plate 403 is connected to the analyzer 301 through a wire. Different signals will be generated when the contact head 402 contacts the contact plate 403 at different positions. This signal will be transmitted to the analyzer 301 through the wire.

[0022] The center end of the contact plate 403 is provided with a balance contact point 404. When the contact head 402 contacts the balance contact point 404, it means that the horizontal bar 401 of the contact head 402 is horizontal in its rotatable plane. When the contact heads 402 in both the transverse horizontal mechanism 4 and the longitudinal horizontal mechanism 5 are in contact with the balance contact point 404 of the contact plate 403, it means that the UAV 1 has reached a horizontal state. The contact plate 403 is bounded by the balance contact point 404. The upper end of the balance contact point 404 is set as the upper contact point 405 and the lower end is set as the lower contact point 406. When the contact head 402 contacts the upper contact point 405, it means that the height of the contact head 402 is low.

[0023] A support foot 6 is provided at the lower end of the base plate 2. The support foot 6 is used to ensure that the UAV 1 is in a horizontal state during take-off and landing. The support foot 6 includes a telescopic cylinder 601, which is fixedly connected to the lower end of the base plate 2. The telescopic cylinder 601 is connected to the analyzer 301. A receiving block 602 is provided at the lower end of the telescopic cylinder 601. A moving rod 603 is movably connected to the lower end of the telescopic cylinder 601. A spring 604 is fixedly connected inside the moving rod 603. The spring 604 is fixedly connected to the lower end of the telescopic cylinder 601. The elastic force generated by all the springs 604 is much less than the weight of the UAV 1 itself and much less than the thrust of the telescopic cylinder 601. A pressing block 605 is fixedly connected inside the spring 604. When the pressing block 605 contacts the receiving block 602, a signal will be generated to stop the telescopic cylinder 601 inside the support foot 6.

[0024] A ball 606 is fixedly connected to the lower end of the moving rod 603. A foot plate 607 is provided at the lower end of the moving rod 603. A spherical shell is provided at the upper end of the foot plate 607. The ball 606 is slidably connected inside the spherical shell, which allows the foot plate 607 to be passively rotated at multiple angles, thereby allowing the foot plate 607 to fit against the inclined surface. An anti-slip groove is provided at the lower end of the foot plate 607, which can increase the friction between the foot plate 607 and the ground and prevent the foot plate 607 from sliding with the ground.

[0025] Working principle: When launching the drone 1, the drone 1 is placed on the ground via the support feet 6. If the ground is uneven, the drone 1 will also tilt. Since the horizontal rod 401 in the horizontal mechanism 4 and the vertical mechanism 5 has the same weight at both ends, it can maintain horizontality. Taking the horizontal mechanism 4 as an example: at this time, the contact head 402 at one end of the horizontal rod 401 is located at the upper contact point 405 of the contact plate 403, and the other contact head 402 is located at the lower contact point 406 of the contact plate 403. The contact plate 403 transmits this information to the analyzer 301. The analyzer 301 analyzes the data and then controls the telescopic cylinder 601 in the lower support foot 6 (the end where the contact head 402 contacts the upper contact point 405 of the contact plate 403) to lift up until the contact head 402 contacts the balance contact point 404 of the contact plate 403. At this time, the horizontal bar 401 in the transverse horizontal mechanism 4 will be parallel to the base plate 2. Similarly, the longitudinal horizontal mechanism 5 can make its internal horizontal bar 401 parallel to the base plate 2. This allows the drone 1 to be placed horizontally on the inclined plane, thereby enabling the drone 1 to take off vertically. When the drone 1 lands, the rangefinder 7 measures the distance between the drone 1 and the ground. When the drone 1 is at a certain height above the ground (about half the extension length of the telescopic cylinder 601), the telescopic cylinder 601 in the four support legs 6 will push the moving rod 603 downward. When the foot plate 607 touches the ground, since the foot plate 607 can slide at multiple angles, it can be made to stick to the ground. The telescopic cylinder 601 continues to press down. Since the foot plate 607 has already touched the ground, the moving rod 603 will be unable to move. At this time, the moving rod 603 will compress the spring 604 to retract until the pressing block 605 contacts the receiving block 602. The receiving block 602 will generate a signal to stop the telescopic cylinder 601 in the support leg 6. When the drone 1 lands on an incline, since the drone 1 is horizontal and the four support legs 6 are independent of each other, their contact with the ground will not change. This is equivalent to keeping the upper part of the four support legs 6 stationary and the lower part in contact with the ground, thus ensuring that the drone 1 lands horizontally.
