[0030] Combine the following Figure 1-Figure 7 The present invention is described in detail.
[0031] Example
[0032] An aircraft cargo hold provided with hard cargo boxes comprises a cabin body 1 with an opening at the upper end, a plurality of first hard cargo boxes 2 stacked up and down are provided in the cabin body 1, an interface device 3 is provided at the bottom of the first hard cargo box 2, a fuse release device 5 fixed on the cabin body 1 is connected to one side of the first hard cargo box 2 close to the side wall of the cabin body 1, and a robotic arm target adapter 4 is provided on the top of the first hard cargo box 2.
[0033] The first hard cargo box 2 is fixed by the interface device 3 and the fuse release device 5 to ensure the transportation stability of the first hard cargo box 2, and a robot arm target adapter 4 is arranged on the first hard cargo box 2 to assist the robot arm 7 in grabbing the first hard cargo box 2.
[0034] Several first hard cargo boxes 2 are divided into multiple groups and the multiple groups of first hard cargo boxes 2 are evenly arranged along the circumference of the cabin 1. Several second hard cargo boxes 6 located inside the multiple groups of first hard cargo boxes 2 are arranged at the bottom of the cabin 1. An interface device 3 is also arranged at the bottom of the second hard cargo box 6, and a robotic arm target adapter 4 is also arranged on the top of the second hard cargo box 6.
[0035] In order to maximize the space utilization of the cargo hold, the first hard cargo boxes 2 are evenly arranged along the circumference of the cabin body 1, and then the second hard cargo boxes 6 are placed at or near the axis of the cabin body 1; several second hard cargo boxes 6 are stacked up and down in two layers, and the second hard cargo boxes 6 are only fixed by the interface device 3. In order to avoid the mechanical environment during the upward movement of the cargo hold affecting the placement stability of the second hard cargo boxes 6, the second hard cargo boxes 6 are stacked in no more than two layers. Figure 1 and 2 Only one set of second hard cargo boxes 6 is shown, and multiple sets can be provided according to the situation.
[0036] The interface device 3 includes a plug 307 fixed to the bottom of the first hard cargo box 2, and the plug 307 is provided with a plurality of step grooves 308 along the circumferential direction. A support 304 which cooperates with the plug 307 is fixedly provided on the top of the first hard cargo box 2 and the bottom of the cabin 1. A slider 302 is vertically slidably provided in the support 304, and a hook 305 which cooperates with the step groove 308 is hinged at the upper end of the slider 302. An elastic puller 306 which is connected to the outer side of the support 304 and is used to pull the hook 305 out of the step groove 308 is provided on the outer side of the hook 305, and the slider 302 is connected to a driving mechanism for driving the slider 302 to rise and fall.
[0037] The slider 302 slides up and down under the drive of the driving mechanism. When the slider 302 moves to the lowermost end, the hook 305 is blocked by the support 304 and deflects inward, thereby hooking into the step groove 308 of the plug 307, thereby fixing the bottom of the first hard cargo box 2; when the slider 302 moves to the uppermost end, a window is opened on the side wall of the support 304, and the hook 305 is pulled by the elastic puller 306 to deflect outward from the window, thereby disengaging from the step groove 308, thereby releasing the lock of the interface device 3. The elastic puller 306 can be an elastic rope or a tension spring.
[0038] The interface device 3 on the second hard cargo box 6 has a plug 307 disposed at the bottom of the second hard cargo box 6 , and the supports 304 are fixedly disposed at the top of the second hard cargo box 6 and the bottom of the cabin 1 , respectively.
[0039] The driving mechanism includes a driving rod 301 connected to a support 304 in a transverse sliding manner. The driving rod 301 is connected to an axial driving device. A transmission member 303 is hinged on the driving rod 301 . One end of the transmission member 303 away from the driving rod 301 is hinged to the slider 302 .
[0040] The axial drive device drives the driving rod 301 to move axially, and the driving rod 301 pulls the slider 302 to move upward through the transmission member 303. When the driving rod 301 is reset, the slider 302 is pulled to move downward. The axial drive device can be an electric telescopic rod, and the power source of the axial drive device is a battery. The axial drive device is wirelessly connected to a controller, so that the controller can be used to control the unlocking and fixing of the interface device 3.
[0041] The upper end surface of the support 304 is provided with a guide block 309 that cooperates with the step groove 308. The guide block 309 cooperates with the step groove 308 to guide the insertion of the plug 307, and at the same time, it can also prevent the relative rotation of the plug 307 and the support 304.
[0042] The robot target adapter 4 includes a column 401, and the upper and lower end surfaces of the column 401 are connected with end plates 404, and the diameter of the end plates 404 is larger than the diameter of the column 401. The column 401 is fixed to the first hard cargo box 2 and the second hard cargo box 6 through the end plates 404 at the lower end, and the end plates 404 at the upper end of the column 401 assist the mechanical claws on the robot arm 7 to hook.
[0043] The side wall of the column 401 is connected with a spacer 402 arranged at intervals, and the upper end surface of the spacer 402 is provided with a socket 403. The number of the spacers 402 is set according to the number of claws of the mechanical claw, and a single claw of the mechanical claw is inserted into the area between two adjacent spacers 402 to ensure that the mechanical claw grabs the correct position; the end surface of the mechanical arm 7 is provided with a positioning pin 8, and when the mechanical claw grabs in place, the positioning pin 8 is inserted into the socket 403 to prevent the hard cargo box from rotating during the transportation process.
[0044] The fuse release device 5 includes a chassis 501 fixed on the inner wall of the cabin 1, and hot knife devices 502 are arranged on both sides of the chassis 501. A fixing rope 505 is arranged around the chassis 501 to contact the hot knife device 502 and is used to bind the first hard cargo box 2. The first hard cargo box 2 is bound and fixed to the chassis 501 by the fixing rope 505. When it needs to be released, the fixing rope 505 can be heated and melted by the hot knife device 502. The hot knife device 502 is connected to the controller by wire or wireless, so that the opening and closing of the hot knife device 502 can be conveniently controlled.
[0045] The end surface of the chassis 501 close to the first hard cargo box 2 is provided with a vibration-damping pad 503, and a top plate 504 is installed on the vibration-damping pad 503 to abut against the first hard cargo box 2. The vibration-damping pad 503 is provided to reduce the impact vibration between the first hard cargo box 2 and the chassis 501, ensuring that the chassis 501 and the first hard cargo box 2 are not damaged.
