The third paracord 182 and the fourth paracord 182 are respectively connected to both sides of the bearing frame 1311, and the connection positions of the third paracord 182 and the fourth paracord 182 on the bearing frame 1311 are symmetrically arranged, so that the bearing Both sides of the frame 131 are force-balanced.

It is worth noting that a side surface of the parachute body 181 is provided with a receiving groove 183 , and the receiving groove 183 is used for receiving the parachute rope 182 . Specifically, the accommodating slot 183 is provided on the side of the parachute body 181 close to the control module 170 , that is, on the side of the parachute body 181 away from the power battery 190 . When the drone body 110 is in normal operation, the paracord 182 is hidden in the receiving groove 183 to improve the appearance and prevent the paracord 182 from interfering with the normal operation of the drone body 110 . When the drone body 110 falls, the parachute body 181 is ejected from the first installation space 1343 . During the process, the parachute rope 182 is pulled out from the receiving groove 183 until it is taut, so as to apply force to the installation frame 134 and the carrier frame 131 . pull.

It should be noted that the parachute rope 182 in the accommodating slot 183 needs to extend out of the accommodating slot 183 and be connected to the mounting frame 134 and the carrier frame 131 respectively, so as to apply tension to the mounting frame 134 and the carrier frame 131 when the parachute body 181 pops up . If the paracord 182 extending out of the receiving groove 183 is not effectively regulated, it is likely to sway or sway, affecting the normal operation of other components in the drone body 110 , and even wrapping around the power assembly 160 , leading to the occurrence of security incidents.

In this embodiment, a plurality of holding parts 1332 are provided on the protective cover 133, and the holding parts 1332 are used to hold the paracords 182, so as to limit the running direction of the paracords 182 and prevent the paracords 182 from being trapped in the drone. During normal operation, the body 110 may vibrate or shake. When the parachute body 181 is ejected, the paracord 182 can be subjected to a taut force, which is far greater than the holding force exerted by the holding member 1332 on the paracord 182, so that the paracord 182 can be disengaged from the holding member 1332, so as to move toward the parachute. The mounting bracket 134 and the carrier bracket 131 exert tension. In this way, the parachute rope 182 will not affect the normal operation of other components in the drone body 110 when the drone body 110 is running normally, and the holder 1332 will not pop up when the drone body 110 falls, that is, the parachute body 181 pops up The position of the parachute rope 182 is limited in time, which is safe, reliable and practical.

Specifically, the plurality of clips 1332 are divided into four groups, each set of clips 1332 is used to define the routing direction of one paracord 182 , and the four sets of clips 1332 can simultaneously limit the routing of four paracords 182 direction. In this embodiment, the number of each group of card holders 1332 is two, but not limited to this. In other embodiments, the number of each group of card holders 1332 may be three or one. For each group The number of the clips 1332 is not specifically limited.

In this embodiment, the holding member 1332 is made of rubber material, the holding member 1332 has elasticity, and the holding member 1332 can hold and limit the paracord 182 through elastic force. But it is not limited to this. In other embodiments, the holding member 1332 can also be made of a silicone material or a plastic material, and the manufacturing material of the holding member 1332 is not specifically limited.

In the UAV system 10 provided by the embodiment of the present invention, the rack 120 is fixedly connected to the UAV body 110, and is arranged at the bottom of the UAV body 110, the rack 120 is used for carrying objects, and the top plate 220 is fixedly installed on the support The top of the rack 210 and the support rack 210 together form a loading and unloading space 230. The top plate 220 is provided with a through hole 221 that communicates with the loading and unloading space 230. 221 protrudes into the loading and unloading space 230 , so that workers can load and unload objects in the loading and unloading space 230 without being affected by the drone body 110 on the top plate 220 . Compared with the prior art, the unmanned aerial vehicle system 10 provided by the present invention adopts the rack 120 disposed at the bottom of the unmanned aerial vehicle body 110 and the top plate 220 with the through hole 221, so it can store the unmanned aerial vehicle in space.
