Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) payload testing technology, and in particular to a UAV payload capacity testing device. Background Technology
[0002] During the production process of drones, their performance needs to be evaluated. Depending on the purpose of the drone, the test items also vary. For cargo drones, load capacity testing is one of the important test items. Currently, load capacity testing is only conducted by adding or removing counterweights. Since the unit weight of the counterweight is fixed, it is difficult to obtain the ultimate load value, resulting in rough test data. In addition, adding counterweights may cause the center of gravity to shift due to structural differences, which may lead to the risk of the device tipping over. This method still needs improvement.
[0003] When drones are used for loaded flights, load tests are required to prevent excessive load from causing the drone to be unable to fly or to fall, thus affecting the normal load capacity. Existing testing devices are not convenient for controlling the size of the counterweight, which in turn affects the efficiency of load testing. Therefore, there is an urgent need for a drone load capacity testing device to solve the above problems. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a device for testing the payload capacity of unmanned aerial vehicles (UAVs). This utility model is achieved through the following technical solution.
[0005] A drone payload capacity testing device includes a drone body, with a hook fixedly connected to the bottom of the drone body, and further includes:
[0006] A gravity traction seat, wherein two limiting slide rods are fixedly connected to the gravity traction seat, and a gravity block is sleeved on the limiting slide rod; a charge controller is fixedly connected to one side of the gravity traction seat.
[0007] An electromagnetic rod, wherein an electromagnetic coil is fixedly wound on the outer surface of the electromagnetic rod, and conductive wires are fixedly connected to both ends of the electromagnetic coil. The electromagnetic rod is fixedly connected to a gravity traction seat through two support plates.
[0008] A metal base, the top of which is fixedly connected to a tension detector, and one end of the tension detector is rotatably connected to a lifting ring.
[0009] Furthermore, the electromagnetic rod is magnetically connected to the metal base.
[0010] Furthermore, the charge controller is electrically connected to both conductive lines.
[0011] Furthermore, the lifting ring is suspended from the hook.
[0012] Furthermore, two limiting grooves are formed on the outer surface of the gravity block, and the gravity block is movably connected to two limiting slide rods through the limiting grooves.
[0013] The beneficial effects of this invention are as follows: During operation, a fixed weight of gravity blocks is first placed on a limiting slide bar. Several gravity blocks can be used for counterweight. Simultaneously, the charge controller is turned on to energize the electromagnetic coil through a conductive wire. Since the electromagnetic coil is wound around an electromagnetic rod, the electromagnetic rod generates a magnetic attraction force. Then, the drone body is moved by controlling the drone body to be hooked onto a lifting ring via a hook. When the drone body is driven upward, it pulls a tension detector through the lifting ring. The tension detector lifts the magnetically connected electromagnetic rod. During the lifting process, the tension detector can detect the magnitude of the tension force. Finally, the charge controller can increase or decrease the charge of the electromagnetic coil, which controls the magnitude of the magnetic attraction force of the electromagnetic rod, thereby adjusting the size of the drone body being lifted. When the drone body is detached from the electromagnetic rod, it is at its maximum load capacity. The structure is reasonable, facilitating the testing of the drone body's maximum load capacity and making adjustment and testing convenient. Attached Figure Description

[0026] like Figure 1-3 As shown, the present invention has the following specific embodiments.
[0027] Example:
[0028] A drone payload capacity testing device includes a drone body 1, with a hook 11 fixedly connected to the bottom of the drone body 1, and also includes:
[0029] Gravity traction seat 2, two limiting slide rods 21 are fixedly connected to the gravity traction seat 2, a gravity block 4 is sleeved on the limiting slide rod 21, and a charge controller 3 is fixedly connected to one side of the gravity traction seat 2.
[0030] Electromagnetic rod 5, with an electromagnetic coil 52 fixedly wound on its outer surface. Both ends of the electromagnetic coil 52 are fixedly connected to conductive wires 521. The electromagnetic rod 5 is fixedly connected to the gravity traction seat 2 through two support plates 51.
[0031] A metal base 6 is fixedly connected to a tension detector 61, and a lifting ring 62 is rotatably connected to one end of the tension detector 61.
[0032] Specifically, the electromagnetic rod 5 is magnetically connected to the metal base 6, and the electromagnetic rod 5 can connect and hoist the metal base 6.
[0033] Specifically, the charge controller 3 is electrically connected to both conductive lines 521.
[0034] Specifically, the lifting ring 62 is suspended and connected to the hook 11, which facilitates the lifting of the lifting ring 62 by the UAV body 1 through the hook 11.
[0035] Specifically, two limiting grooves 41 are provided on the outer surface of the gravity block 4, and the gravity block 4 is movably connected to the two limiting slide rods 21 through the limiting grooves 41. The limiting grooves 41 enable the gravity block 4 to be limited and connected to the limiting slide rods 21.
[0036] The working principle of this utility model:
[0037] When using the device, first, a fixed-weight gravity block 4 is placed on the limiting slide bar 21. Several gravity blocks 4 can be used for counterweighting. Simultaneously, the charge controller 3 is turned on, energizing the electromagnetic coil 52 via the conductive wire 521. Since the electromagnetic coil 52 is wound around the electromagnetic rod 5, the electromagnetic rod 5 generates a magnetic attraction force. Then, the drone body 1 is moved by controlling the drone body 1, causing it to be hooked onto the lifting ring 62 via the hook 11. When the drone body 1 is driven upwards, the lifting ring 62 pulls the drone body 1, causing a pulling force detection. The tensile detector 61 is used for lifting via six pairs of magnetically connected electromagnetic rods 5. During the lifting process, the tensile detector 61 can detect the magnitude of the tensile force. Finally, the charge controller 3 can increase or decrease the charge of the electromagnetic coil 52, which can control the magnitude of the magnetic attraction of the electromagnetic rods 5, thereby adjusting the size of the drone body 1 to be lifted. When the drone body 1 is detached from the electromagnetic rods 5, the drone body 1 is at its maximum load value. The structure is reasonable, which facilitates testing the maximum load of the drone body 1 and makes adjustment and testing convenient.
