[0028] It should be noted that the reference direction is with the test section above, the lifting assembly below, and the two wings on the left and right respectively.

[0029] Please see Figure 1 This utility model provides an auxiliary device for testing the center of gravity of a drone, including a test frame 1, a support mechanism 2, and a fixing component 3. The test frame 1 is provided with a test section 101 for fixing the drone. The test frame 1 includes a support base 102, a support rod 103, and a mounting base 104 arranged sequentially from bottom to top. The support rod 103 is bent away from the fixing component 3, and its two ends are connected to the support base 102 and the mounting base 104, respectively. The test section 101 is connected to the mounting base 104. In this embodiment, a fixing ring is provided at the bottom of the mounting base 104. The test section 101 is a structure that can realize the center of gravity test, such as a suspension rope, a suspension rod, or a clamping device. No limitation is made here. The suspension rope passes through the fixing ring, and its two ends are used to connect to the wing of the drone. The support mechanism 2 includes a lifting component 21 and a support section 22. The support section 22 has a placement area for accommodating the drone. The lifting assembly 21 drives the support part 22 to reciprocate between the support position and the sinking position. The fixing assembly 3 is fixedly connected to the testing part 101. The fixing assembly 3 has two receiving slots 35 for accommodating the drone's wings. The two wings of the drone are respectively placed into the two receiving slots 35. After the two ends of the fixing assembly 3 are detachably connected to the two ends of the suspension rope, the lifting assembly 21 drives the support part 22 to descend to the sinking position. The support part 22 separates from the drone, and the drone's wings are in a horizontal state. The tilt angle of the drone in the forward and backward direction is tested by the testing device to determine whether the drone's center of gravity has shifted. When the drone needs to be placed, the height of the support part is lowered by the lifting assembly. After the drone is placed, the height of the support part is raised. After the drone is fixed, the height of the support part is lowered again to detect the center of gravity of the drone. This reduces the difficulty of manual operation and makes the operation convenient and quick.

[0030] Please see Figure 2 Specifically, in an optional embodiment of this application, the fixing component 3 includes a first fixing member 31, a second fixing member 32, and a connecting member 33. The first fixing member 31 and the second fixing member 32 are connected by the connecting member 33. The first fixing member 31 and the second fixing member 32 are arranged opposite to each other, and the opposite surfaces of the first fixing member 31 and the second fixing member 32 are provided with the receiving groove 35. The first fixing member 31 and the second fixing member 32 are respectively fitted onto the left and right wings of the UAV through the receiving groove 35, and then the first fixing member 31 and the second fixing member 32 are connected together by the connecting member 33 to avoid the first fixing member 31 or / and the second fixing member 32 slipping off during the measurement process.

[0031] Specifically, in an optional embodiment of this application, the first fixing member 31 includes a first connecting part 311 and a second connecting part 312. Both the first connecting part 311 and the second connecting part 312 are elongated plate-like structures. The first connecting part 311 and the second connecting part 312 are arranged opposite to each other, and the opposite surfaces of the first connecting part 311 and the second connecting part 312 are provided with grooves. The two grooves form the receiving groove 35. The second connecting part 312 has the same structure as the first connecting part 311.

[0032] Please see Figure 3 Specifically, in an optional embodiment of this application, the first fixing member 31 further includes an adjustment part 34, which has an adjustment groove. The adjustment part 34 is detachably disposed in the receiving groove 35. The adjustment part 34 can be replaced according to the size of the UAV wing. Different adjustment parts 34 have different sizes of adjustment grooves, thereby adapting to different models of UAVs and improving the measurement range.

[0033] Specifically, in an optional embodiment of this application, the first connecting part 311 is provided with a scale groove 313 evenly along the length direction of the drone wing on the surface opposite to the second connecting part 312, and the first connecting part 311 of the first fixing member 31 and the first connecting part 311 of the second fixing member 32 are symmetrically arranged. The scale groove 313 can accurately find the horizontal position of the drone in the left and right directions.

[0034] Specifically, in an optional embodiment of this application, a connecting ring 314 is sleeved on the first fixing member 31. The connecting ring 314 is disposed in the scale groove 313. The connecting ring 314 is provided with a plurality of mounting holes for connecting with the test part 101, which facilitates the adjustment of the installation position of the connecting ring 314. The scale groove 313 can also limit the position of the connecting ring 314.

[0035] Specifically, in an optional embodiment of this application, the connecting ring 314 includes a first ring portion and a second ring portion, both of which are semi-elliptical structures. One end of the first ring portion and one end of the second ring portion are hinged together, and the other end of the first ring portion and the other end of the second ring portion are snapped together, which facilitates installation in different scale grooves 313.

[0036] Specifically, in one optional embodiment of this application, the lifting assembly 21 includes a guide plate 211, a driving component 212, and a plurality of mounting rods 213. The guide plate 211 is fixed on the test frame 1. The guide plate 211 is provided with a plurality of threaded guide holes, the number of which is the same as the number of mounting rods 213. Each mounting rod 213 passes through a corresponding threaded guide hole. The first end (upper end) of the mounting rod 213 is a threaded rod, and the first end of the mounting rod 213 is located in the threaded guide hole. The grooved groove serves to limit the first end of the mounting rod 213 to prevent it from falling off. The second end (lower end) of the mounting rod 213 has a toothed cross-section. The output end of the driving member 212 is connected to the transmission gear. The transmission gear meshes with the second ends of multiple mounting rods 213. The driving member 212 drives the transmission gear to rotate. The transmission gear is located in the middle of multiple mounting rods 213, so the transmission gear drives the second ends of multiple mounting rods 213 to rotate, and finally drives the mounting rods 213 to move up and down, so that the support part 22 reciprocates between the support position and the settlement position.

[0037] Specifically, in an optional embodiment of this application, the support portion 22 is provided with a plurality of adjusting rods 221 and a plurality of buffer pads 222 on the surface opposite to the lifting assembly 21. The plurality of adjusting rods 221 are evenly arranged on the edge of the support portion 22. One end of the adjusting rod 221 is connected to the support portion 22, and the other end of the adjusting rod 221 is connected to the buffer pad 222. When the center of gravity of the drone is unstable, the buffer pad 222 plays a buffering role for the drone.

[0038] Specifically, in an optional embodiment of this application, the first fixing member 31 and the second fixing member 32 are provided with connecting hooks on the surfaces facing the support portion 22. The connecting member 33 includes a telescopic portion and two hook portions.
