Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figures 1-4 As shown, this embodiment provides a test apparatus for a drone suspension device, used to test a drone suspension device 100. The drone suspension device 100 includes a winding reel 1001, a first motor, a rope, and a base shell 1002.

Both the winding reel 1001 and the first motor are disposed inside the base shell 1002. A cable passage hole is provided at the bottom of the base shell 1002, through which the rope extends to the bottom of the base shell 1002.

[0043] The test apparatus for a drone suspension device includes a first support beam 1, a second support beam 2, a first drive assembly 3, a second drive assembly 4, and a suspension mechanism 5. The first support beam 1 extends along a first direction, and the second support beam 2 extends along a second direction perpendicular to the first direction. The rotation axis of the winding reel 1001 is parallel to the second direction.

The first limiting plate 421 and the second limiting plate 422 are disposed on both sides of the second support beam 2, and the connecting shaft 423 connects the first limiting plate 421 and the second limiting plate 422. In this embodiment, the first limiting plate 421 is disposed on the upper side of the second support beam 2, and the second limiting plate 422 is disposed on the lower side of the second support beam 2.

The cooperation between the second guide roller 424 and the second guide groove 21 guides the movement of the third motor 41 and the UAV suspension device 100 along the second direction.

[0053] Optionally, such as Figure 1 and Figure 2 As shown, the suspension mechanism 5 includes a third drive assembly 51, which is mounted on the second drive assembly 4. The UAV suspension device 100 is mounted on the third drive assembly 51. The third drive assembly 51 drives the UAV suspension device 100 to rotate around a first axis. The rotation axis, first direction, and second direction of the winding reel 1001 are all perpendicular to the first axis. By setting the third drive assembly 51, the test device for the UAV suspension device can drive the UAV suspension device 100 to rotate around a first axis perpendicular to the horizontal plane, thereby simulating the yaw axis of the UAV through the first axis to test the effect of the UAV yaw angle on the UAV suspension device 100.

[0054] Furthermore, such as Figure 1 and Figure 2 As shown, the third drive assembly 51 includes a fourth motor 511 and a mounting bracket 512.

[0055] Optionally, the suspension mechanism 5 further includes a fourth drive assembly, which is mounted on the mounting bracket 512. The UAV suspension device 100 is mounted on the fourth drive assembly. The third drive assembly 51 can drive the fourth drive assembly to rotate around a first axis, and the UAV suspension device 100 can rotate with the fourth drive assembly around the first axis. The fourth drive assembly is used to drive the UAV suspension device 100 to rotate around a second axis, which is parallel to the rotation axis of the winding reel 1001. By setting the fourth drive assembly, the test device for the UAV suspension device can drive the UAV suspension device 100 to rotate around a second axis parallel to the horizontal direction, thereby simulating the pitch axis of the UAV through the second axis to test the effect of the UAV pitch angle on the UAV suspension device 100. Preferably, the second axis is collinear with the rotation axis of the winding reel 1001.

[0056] Furthermore, the fourth drive assembly includes two fifth motors. The mounting bracket 512 includes a left mounting bracket and a right mounting bracket, which are respectively disposed on both sides of the fourth motor 511. The two fifth motors are respectively disposed on the left mounting bracket and the right mounting bracket, that is, one fifth motor is disposed on the left mounting bracket and one fifth motor is disposed on the right mounting bracket. The output shafts of the two fifth motors are connected to the UAV suspension device 100 for transmission. The fifth motors can drive the UAV suspension device 100 to rotate around the second axis. The two fifth motors cooperate to drive the UAV suspension device 100 to rotate around the second axis.

[0057] Furthermore, the test apparatus for the drone suspension device in this embodiment also includes a controller. The first motor, the second motor 31, the third motor 41, the fourth motor 511, and the fifth motor are all communicatively connected to the controller. The operator controls the drone suspension device 100, the first drive assembly 3, the second drive assembly 4, the third drive assembly 51, and the fourth drive assembly through the controller. This controls the rope release length of the drone suspension device 100, the movement of the drone suspension device 100 along a first direction, the movement of the drone suspension device 100 along a second direction, the rotation of the drone suspension device 100 around a first axis, and the rotation of the drone suspension device 100 around a second axis, thereby testing the state of the drone suspension device 100 under various movement states of the drone and under different rope release lengths.

[0058] In summary, the test apparatus for the UAV suspension device provided in this embodiment can simulate the two-dimensional movement of the UAV in the horizontal direction. Furthermore, during the simulation of the two-dimensional movement of the UAV in the horizontal direction, the UAV suspension device 100 can be driven to rotate around the first axis and the second axis to simulate the influence of the UAV's yaw angle and pitch angle on the UAV suspension device 100.
