[0024] like Figure 5-6 As shown, this example can achieve the effect of facilitating the goods to enter the storage box 101 by sliding into it.

[0025] Since the drone loading and unloading device includes a storage box 101, pads 102 are welded at the four corners of the lower side of the storage box 101, an inclined plate 208 is provided at the lower left part of the storage box 101, and a guardrail 103 is connected to the right side of the storage box 101 by screws. The pads 102 can lift the storage box 101, and then the cargo can slide onto the storage box 101 through the inclined plate 208, thereby facilitating the cargo to slide into the storage box 101, stably transporting the cargo, and preventing the cargo from falling off when entering the storage box 101 by clamping alone.

[0026] like Figure 5-6 As shown, this example can achieve the effect of facilitating loading heavier goods into the storage box 101 .

[0027] Since slideways 106 are provided on both the front and rear sides of the inner side of the storage box 101, each slideway 106 is slidably connected to a slide seat 201, and a lifting frame 203 is vertically slidably connected to the slide seat 201, and a motor 202 is connected to the lifting frame 203 by screws, and a rotating arm 207 is connected to the output shaft of the motor 202, and a clamping column 206 is welded to the end of the rotating arm 207, and a telescopic rod 1 204 is connected to the slide seat 201 by screws, and the movable end of the telescopic rod 1 204 is connected to the lifting frame 203 by screws, and the slide seat 201 is on the slideway. When the telescopic rod 104 is extended, the two rotating arms 207 are extended, and then the two rotating arms 207 are driven to rotate by the two motors 202 respectively, and then the goods are clamped by the two clamping columns 206 on the two rotating arms 207, and then the telescopic rod 1 204 is extended to drive the motor 202, the rotating arms 207 and the clamping columns 206 to lift up, and then lift the goods upward, and then drive the two slides 201 to move to the right, and then drive the goods to move to the right and slide along the inclined plate 208 into the storage box 101, so as to facilitate the loading of heavier goods into the storage box 101.

[0028] like Figure 5-6 As shown, this example can achieve the effect of increasing the friction force when the clamping column 206 clamps the goods.

[0029] Since the clamping column 206 is provided with a plurality of convex ridges 205 in a ring shape, the convex ridges 205 increase the friction force when the clamping column 206 clamps the goods.

[0030] like Figure 5-6 As shown, this example can achieve the effect of driving the slide 201 to slide left and right on the slideway 106.

[0031] Since the front and rear ends of the barrier 103 are connected to the motor 104 by screws, the output shaft of the motor 104 is connected to the screw rod 105, and the screw rod 105 is threadedly connected to the slide 201, the motor 104 drives the screw rod 105 to rotate, thereby driving the slide 201 to slide left and right on the slide 106.

[0032] like Figure 5-7 As shown, this example can achieve the effect of lifting the storage box 101 through the bottom fork 301.

[0033] Since bottom grooves 107 are provided at both the front and rear ends of the lower side of the storage box 101 , the bottom fork 301 is inserted into the two bottom grooves 107 , and the storage box 101 can be lifted by the bottom fork 301 .

[0034] like Figure 5-7 As shown, this example can achieve the effect of preventing the storage box 101 and the bottom fork 301 from falling off.

[0035] Since a socket 108 is welded to the right side of the storage box 101, a boss 305 is welded on the bottom fork 301, and a plug post 307 is slidably connected to the boss 305, and the plug post 307 can be inserted into the socket 108. A telescopic rod 2 306 is connected to the boss 305 by screws, and the movable end of the telescopic rod 2 306 is connected to the end of the plug post 307 by screws. A convex plate 302 is provided in the middle of the right side of the bottom fork 301, and when the bottom fork 301 moves from right to left, it can be inserted into the two bottom grooves 107. When the convex plate 302 contacts the socket 108, the bottom fork 301 stops moving. At this time, the plug post 307 is driven by the telescopic drive of the telescopic rod 2 306 to slide on the boss 305, and the plug post 307 can be inserted into the socket 108. At this time, the bottom fork 301 is locked to the lower side of the storage box 101, thereby preventing the storage box 101 and the bottom fork 301 from falling off.

[0036] like Figure 5-9 As shown, this example can facilitate the insertion of the bottom fork 301 into the two bottom grooves 107 .

[0037] Since a cross bar 308 is welded to the right side of the convex plate 302, the cross bar 308 is slidably connected to the lower part of the vertical arm 401, and the right end of the cross bar 308 is connected to the motor 304 through a screw, and the output shaft of the motor 304 is connected to the screw rod 2 303, and the screw rod 2 303 is threadedly matched with the vertical arm 401. The motor 304 drives the screw rod 2 303 to rotate, thereby driving the cross bar 308 to move left and right on the vertical arm 401, and then driving the bottom fork 301 to move left and right, so as to facilitate the bottom fork 301 to be inserted into the two bottom grooves 107.

[0038] like Figure 8-9 As shown, this example can achieve the effect of preventing the goods in the storage box 101 from sliding out from the left side.

[0039] Since the upper part of the vertical arm 401 is rotatably connected to the fixed shaft 408, shaft seats 407 are welded to the front and rear ends of the fixed shaft 408, and the two shaft seats 407 are welded to the lower side of the connecting plate 403, the vertical arm 401 can rotate on the fixed shaft 408, thereby driving the vertical arm 401 to rotate on the fixed shaft 408 to a tilted state, thereby making the storage box 101 higher on the left and lower on the right, thereby preventing the goods in the storage box 101 from sliding out from the left side.

[0040] like Figure 8-9 As shown, this example can achieve the effect of driving the storage box 101 to become a state where the left is high and the right is low.

[0041] Since the right side of the connecting plate 403 is welded with a vertical bar 409, the left side of the connecting plate 403 is welded with an L-shaped rod 402, a compression spring is welded on the L-shaped rod 402, and the other end of the compression spring is welded on the left side of the vertical arm 401, a lifting block 405 is vertically slidably connected to the vertical arm 401, a slope 404 is arranged on the right side of the lifting block 405, and the slope 404 presses against the lower part of the vertical bar 409, and a telescopic rod 3 406 is connected to the vertical arm 401 through screws, and the movable end of the telescopic rod 3 406 is connected to the lifting block 405 through screws. The compression spring always gives the vertical arm 401 a rightward force, so that the vertical arm 401 always has a tendency to rotate counterclockwise, and the lifting block 405 is driven to move upward on the vertical arm 401 through the telescopic rod 3 406, and then presses against the lower end of the vertical bar 409 through the slope 404, thereby driving the vertical arm 401 to rotate clockwise, thereby driving the storage box 101 to change to a state where the left side is higher and the right side is lower.

[0042] like Figure 8-9 As shown, this example can achieve the effect of completing the loading and unloading of goods.

[0043] Since the connecting plate 403 is connected to the drone by screws, when the drone lands on the ground, it can be inserted into the storage box 101 through the bottom fork 301, thereby completing the connection between the bottom fork 301 and the storage box 101, and then the loading and unloading of goods can be completed through the two clamping columns 206 in the storage box 101.
