One end of the handrail assembly 2 is connected to the vehicle body frame 1 through the mounting interface; the handrail assembly 2 can rotate around point O; point O is the position where the mounting interface is located. When the handrail assembly 2 rotates to a certain position, the limiting rod 3 is inserted into the square hole of the vehicle body frame 1 to limit the downward movement of the handrail assembly 2. The four universal wheels 4 are evenly distributed at the bottom of the vehicle body frame 1. It should be noted that the front (front end), rear (end), etc. described in the embodiments of the present invention are all referenced based on the forward direction of the lightweight UAV transporter.

[0041] In this embodiment, the handrail assembly 2 may specifically include: a handrail A 201, a handrail B 202, and an arc steel plate 203. Among them, the structures, dimensions, and installation methods of the handrail A 201 and the handrail B 202 are exactly the same.

[0042] Preferably, mounting interfaces A 102 and B 103 are provided on the longitudinal beam 101 of the vehicle body frame 1. Among them, one end of the handrail A 201 is screwed to one end of the outer threaded rod end joint bearing A 5, and the other end of the outer threaded rod end joint bearing A 5 is connected to the mounting interface A 102 through a pin A 6. One end of the handrail B 202 is screwed to one end of the outer threaded rod end joint bearing B, and the other end of the outer threaded rod end joint bearing B is connected to the mounting interface B 103 through a pin B. An arc steel plate 203 is welded between the front ends of the handrail A 201 and the handrail B 202.

[0043] Preferably, the handrail A 201 and the handrail B 202 are of a three-section structure, including: a front arc section 2001, a long straight section 2002, and a rear arc section 2003. Among them, the front arc section 2001 is arc-shaped and is designed to conform to the arc steel plate 203; the arc dimensions of the front arc section 2001 and the arc steel plate 203 are the same as the diameter of the lightweight UAV tire. The rear arc section 2003 is designed according to ergonomics for convenient lifting. In the free state, the handrail assembly 2 is on the ground, and the long straight section 2002 is flush with the ground.

[0044] Preferably, the width of the arc steel plate 203 is the same as the width of the lightweight UAV tire, and the distance between the mounting interface A 102 and the mounting interface B 103 is greater than the width of the lightweight UAV tire, which ensures that the lightweight UAV tire can be smoothly placed on the handrail assembly 2 while ensuring the stability of the lightweight UAV tire on the handrail assembly 2 and avoiding its shaking.

[0045] Preferably, square holes A and B are respectively provided on cross beam A104 and cross beam B105 of the vehicle body frame 1. Among them, square hole A and square hole B are respectively located at the ends of cross beam A104 and cross beam B105, and are used for installing the limit rod 3.

[0047] In this embodiment, the armrest assembly 2 is relatively long. By the lever principle, the drone can be easily lifted. A single armrest can lift a 600-kilogram drone by applying a pulling force of 30 kilograms. Based on the lever principle, the lever arm length ratio can be expressed as L1:L2 = 1:N. Among them, L1 represents the vertical distance from point P to the front end of the armrest, and L2 represents the vertical distance from point P to the end of the armrest; point P is: the position where the center point of the light drone tire is located when the light drone tire is placed on the armrest assembly 2; N is a constant, N≥10.

[0048] In this embodiment, the working process of the light drone transporter is as follows: Move the light drone transporter to the position of the light drone tire, pull out the limit rod 3 from the square holes A and B, and place the armrest assembly 2 in contact with the ground. Place the light drone tire on the armrest assembly 2. Apply a lifting force to the ends of the armrest A201 and the armrest B202, and the ends of the armrest A201 and the armrest B202 are lifted. When the ends of the armrest A201 and the armrest B202 are lifted to a certain height and the long straight section 2002 is above the square holes A and B, insert the limit rod 3 into the square holes A and B. Release the lifting force on the ends of the armrest A201 and the armrest B202, and the armrest A201 and the armrest B202 move downward under the action of gravity until they are limited by the limit rod 3 and no longer move downward.
