The first cross plate is installed at the bottom of the first push rod.

[0018] The present invention provides a cargo hold retracting device for a low-altitude economic freight unmanned aerial vehicle, having the following beneficial effects:

[0019] 1. The cargo compartment retracting and deploying device of the low-altitude economy cargo drone divides and protects the cargo by setting up a control mechanism, a placement mechanism, and a protection mechanism. When retracting and deploying the cargo, since the cargo compartment is set as an integral space, it is difficult to take the cargo deep in the cargo compartment. If the electric push method is directly used to push it out, the cargo and the retracting and deploying personnel are vulnerable to injury. Therefore, a control mechanism, a placement mechanism, and a protection mechanism are set up. By setting four partitions on the disc, the disc is divided into four areas, and corresponding protection mechanisms are set for the four areas to protect the cargo individually. And a control mechanism is set at the bottom of the disc to control the angle of the disc, thereby adjusting the placement area facing the retracting and deploying personnel, facilitating the retracting and deploying personnel to retract and deploy the cargo, and solving the above problems.

[0020] 2. The cargo compartment retracting and deploying device of the low-altitude economy cargo drone divides the cargo into different areas by setting up a placement mechanism. By setting four partitions on the disc, the disc is divided into four areas, and then the cargo is placed in the four different areas. And two fixed boxes are arranged outside each partition. According to the placement conditions of the cargo, temperature control materials can be placed in the fixed boxes to control the temperature of the cargo in each area individually.

[0021] 3. The cargo compartment retracting and deploying device of the low-altitude economy cargo drone surrounds and protects the cargo by setting up a protection mechanism. When the device is in the state of retracting and deploying the cargo, the second push rod is in the open state. At this time, the protection mechanism is away from the cargo, and the retracting and deploying personnel can manually take the cargo or manually clean and adjust the contact components. When the device finishes retracting and deploying the cargo, the second push rod is in the initial state. At this time, the first clamping rod is in the through hole, and the second clamping rod is in the clamping hole to intercept and protect the cargo.

[0022] 4. The cargo compartment retracting and deploying device of the low-altitude economy cargo drone protects the top of the cargo by setting up contact components. According to the shape of the cargo, the angle of the contact plate in the hinge can be adjusted so that the contact plate and the friction strip contact and press the top of the cargo. At this time, the second cross plate deforms slightly according to the shape of the top of the cargo. Two contact components are arranged in each protection mechanism, which is convenient for the contact and fixing work of the cargo with different top shapes at two positions. And an elastic pad is arranged on the top of the circular plate. With the takeoff and landing of the drone, the elastic pad contacts the cargo with the circular plate, which can provide a buffer space for the cargo and avoid the situation that the cargo is locally deformed due to hard pressing.

[0023] 5. The cargo compartment retracting and extending device of this low-altitude economy cargo drone controls the angle of the disc by setting up a control mechanism. The motor is used to control the rotation of the rotating shaft and the disc, and then control the rotation of the four placement areas and the goods, facilitating the placement and retrieval of goods by the operators. During the rotation of the disc, the support member is always within the double ring, providing limit support for the disc and making the position of the disc more stable. When the device is installed on the drone, the first push rod is in the open state, and the suction cup is suction-fixed on the bottom plate of the drone, enhancing the stability of the device and preventing the goods from falling due to the shaking of the drone.

The second clamping rod 504 is used to connect with the clamping holes 407. A plurality of second clamping rods 504 are provided.

[0043] When the equipment is in the state of loading and unloading goods, turn on the second push rod 403. The second push rod 403 drives the top plate 501 to move upward, and then drives the protection mechanism 5 to move upward. At this time, the protection mechanism 5 is away from the goods, and the loading and unloading personnel can manually take the goods or manually clean and adjust the contact component 506.

[0044] When the loading and unloading of goods by the equipment is completed, adjust the second push rod 403 to the initial state. At this time, the first clamping rod 503 is in the through hole 404, and the second clamping rod 504 is in the clamping hole 407 to intercept and protect the goods.

[0045] The contact component 506 includes an elastic pad 5061. A circular plate 5062 is installed outside the elastic pad 5061. Hinges 5063 are arranged outside the circular plate 5062.

The contact plate 5064 is made of elastic material. A friction strip is installed outside the contact plate 5064. The elastic pad 5061 is installed outside the third push rod 505.

[0046] The contact assembly 506 further includes a second adjusting rod 5065. A second cross plate 5066 is installed at the bottom of the second adjusting rod 5065. The second cross plate 5066 is made of an elastic material. An adjusting column 5067 is installed outside the second cross plate 5066. There are four adjusting columns 5067, and the four adjusting columns 5067 are respectively connected to the four contact plates 5064. The second adjusting rod 5065 is installed inside the circular plate 5062.

[0047] According to the shape of the top of the goods, manually adjust the length of the adjusting column 5067. The adjusting column 5067 drives the contact plate 5064 to rotate in the hinge 5063, thereby adjusting the angle of the contact plate 5064.

[0048] When the second push rod 403 is in the initial state, at this time, the first clamping rod 503 is in the through hole 404, and the second clamping rod 504 is in the clamping hole 407. Turn on the third push rod 505. The third push rod 505 drives the elastic pad 5061, the circular plate 5062, the hinge 5063, the contact plate 5064, the second adjusting rod 5065, the second cross plate 5066 and the telescopic rod to move downward. The contact plate 5064 contacts and presses the top of the goods with the friction strip. At this time, the second cross plate 5066 undergoes slight deformation according to the shape of the top of the goods. Two contact assemblies 506 are provided in each protection mechanism 5, which is convenient for the contact and fixing work at two positions for goods with different top shapes. And an elastic pad 5061 is provided on the top of the circular plate 5062. As the drone takes off and lands, the elastic pad 5061 contacts the goods with the circular plate 5062, which can provide a buffer space for the goods and avoid local deformation of the goods caused by hard pressing.

[0049] The control mechanism 3 includes a motor box 301. A connecting plate 302 is installed outside the motor box 301. A support member 303 is provided at the top of the connecting plate 302.

[0052] Before loading and unloading goods, start the motor. The motor drives the rotating shaft 2 to rotate, and then drives the disc 1 to rotate, so as to adjust the directions of the four placement areas, facilitating the loading and unloading personnel to pick up or place goods. And during the rotation of the disc 1, the support member 303 is always inside the double ring 401, providing limit support for the disc 1 to make the position of the disc 1 more stable.

[0053] When the device is on the bottom plate of the drone, the first push rod 305 is in the open state, the first cross plate 3061 is still inside the through groove 304, and the suction cup 3063 lands. By manually pressing the top plate 501, the suction cup 3063 is suction-fixed to the bottom plate of the drone, strengthening the stability of the device and preventing the goods from falling due to the shaking of the drone.

[0054] Working principle: Before using the device, adjust the protection mechanism 5 and the control mechanism 3. The loading and unloading personnel manually place the goods in the placement mechanism 4. Before loading and unloading goods, start the motor. The motor drives the rotating shaft 2 to rotate, and then drives the disc 1 to rotate, so as to adjust the directions of the four placement areas, facilitating the loading and unloading personnel to pick up or place goods. And during the rotation of the disc 1, the support member 303 is always inside the double ring 401, providing limit support for the disc 1 to make the position of the disc 1 more stable. Start the second push rod 403. The second push rod 403 drives the top plate 501 to move upward, and then drives the protection mechanism 5 to move upward. At this time, the protection mechanism 5 is away from the goods, and the loading and unloading personnel can manually pick up the goods or manually clean and adjust the contact assembly 506.

[0055] When the device finishes loading and unloading goods, adjust the second push rod 403 to the initial state. At this time, the first clamping rod 503 is in the through hole 404, and the second clamping rod 504 is in the clamping hole 407 to intercept and protect the goods.

[0056] According to the shape of the top of the goods, manually adjust the length of the adjusting column 5067. The adjusting column 5067 drives the contact plate 5064 to rotate in the hinge 5063, and then adjusts the angle of the contact plate 5064.

[0057] When the second push rod 403 is in the initial state, the first clamping rod 503 is in the through hole 404 and the second clamping rod 504 is in the clamping hole 407 at this time. When the third push rod 505 is activated, the third push rod 505 drives the elastic pad 5061, the circular plate 5062, the hinge 5063, the contact plate 5064, the second adjusting rod 5065, the second cross plate 5066 and the telescopic rod to move downward. The contact plate 5064 contacts and presses the top of the goods, and at this time, the second cross plate 5066 undergoes slight deformation according to the shape of the top of the goods. Two contact components 506 are provided in each protection mechanism 5, which is convenient for the contact and fixation work at two positions for goods with different top shapes. And an elastic pad 5061 is provided on the top of the circular plate 5062. As the drone takes off and lands, the elastic pad 5061 contacts the goods with the circular plate 5062, which can provide a buffer space for the goods and avoid local deformation of the goods caused by hard pressing.

[0058] After placing the device on the drone, adjust the control mechanism 3 to reinforce the position of the device. When the device is on the bottom plate of the drone, the first push rod 305 is in the activated state, the first cross plate 3061 is still inside the through groove 304, and the suction cup 3063 lands. By manually pressing the top plate 501, the suction cup 3063 is suction-fixed on the bottom plate of the drone to enhance the stability of the device and avoid the situation of the goods falling due to the shaking of the drone.
