Description

Technical Field

[0001] The utility model relates to the technical field of rear flip doors, and specifically relates to a rear flip door structure of a drone with good load-carrying capacity. Background Technique

[0002] Drones have certain application potential in transporting materials. Especially in situations where speed, flexibility, and high terrain requirements are needed, the model and design of drones determine the maximum payload they can carry and the flight distance. Some large drones can carry dozens or even hundreds of kilograms of goods, but the flight distance is easily limited by battery life or fuel capacity. Drones are usually equipped with highly automated flight control systems and can perform flight tasks through preset waypoints or remote control operations;

[0003] After the drone transports materials to the target location through the flight control system, it is necessary to flip open the rear flip door to take out the materials. Since the staff needs to step on the rear flip door when taking out the materials after the rear flip door is opened, and the drone generally needs to reduce a certain amount of its own weight, the structural strength of the general rear flip door is limited, resulting in poor load-carrying capacity of the rear flip door and easy deformation. Therefore, we propose a rear flip door structure of a drone with good load-carrying capacity. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rear flip door structure of a drone with good load-carrying capacity to solve the problems raised in the above background technique that the drone generally needs to reduce a certain amount of its own weight, resulting in limited structural strength of the general rear flip door, poor load-carrying capacity of the rear flip door, and easy deformation.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rear flip door structure of a drone with good load-carrying capacity, including a rear flip door frame and a rear flip door body. One side of the rear flip door frame is movably connected to the rear flip door body through a hinge. Sealing strips are respectively fixed on the inner side of the rear flip door frame and the outer side of the rear flip door body, and a torsion spring is sleeved on the rotating shaft of the hinge. Connecting plates are respectively fixed on the outer sides of the rear flip door frame and the rear flip door body. A connecting layer is inlaid on one side of the rear flip door body close to the rear flip door frame, and a patterned aluminum plate is fixed on the outer side of the connecting layer. A reinforcing frame is inlaid on the side of the rear flip door body away from the patterned aluminum plate.

[0006] Preferably, one side of the connecting plate is slidably butted with a docking rod through a rotating shaft, and a docking tube is sleeved at one end of the docking rod.

[0007] Preferably, a first spring is sleeved at one end of the docking rod, and both ends of the first spring are fixed to the docking rod and the docking tube respectively.

[0008] Preferably, one end of the second spring is fixed to the outer side of the docking pipe, and the other end of the second spring is connected to the connecting plate.

[0009] Preferably, a fixed pipe is connected to one side of the rear flip door main body close to the reinforcing frame, and the fixed pipe is slidably docked with the sliding frame.

[0010] Preferably, the sliding frame is docked with the third spring, and both ends of the third spring are fixed to the fixed pipe and the sliding frame respectively.

[0011] Preferably, the lower end of the sliding frame is docked with the connecting pad, and a fixing ring is embedded on the outer side of the connecting pad.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the rear flip door structure of the drone with good load capacity, when the staff steps on the rear flip door main body to take out the material, the pattern aluminum plate ensures anti-slip while strengthening the strength of the rear flip door main body, and the fixed reinforcing frame can further prevent the rear flip door main body from deforming, strengthening the load capacity of the rear flip door main body. The connecting pad and the sliding frame are restricted together, and the rear flip door main body drives the connecting pad to fit with the ground, so that the sliding frame pulls the third spring, buffering the impact force generated by the flipping of the rear flip door main body, and reducing the impact force when the rear flip door main body is flipped open.

[0013] 1. For the rear flip door structure of the drone with good load capacity, the drone can ensure stable flight and accurate target arrival through the flight control system, which is suitable for long-distance or fixed-point delivery tasks. When the drone transports materials to the target location, it is necessary to flip open the rear flip door main body, and the rear flip door main body pulls the docking rod. When the staff steps on the rear flip door main body to take out the material, due to the certain strength and stability of the connecting layer, the pattern aluminum plate ensures anti-slip while strengthening the strength of the rear flip door main body, and the fixed reinforcing frame can further prevent the rear flip door main body from deforming, enabling the rear flip door main body to improve the structural strength and strengthen the load capacity of the rear flip door main body;

[0014] 2. For the rear flip door structure of the drone with good load capacity, when the rear flip door main body rotates and opens close to the ground, first socket the connecting pad and the sliding frame together to restrict the connecting pad and the sliding frame together. The rear flip door main body drives the connecting pad to fit with the ground, so that the connecting pad can buffer the impact force of the rear flip door main body on the ground when flipping, and at this time, the sliding frame slides along the fixed pipe under force, making the sliding frame pull the third spring, further buffering the impact force generated by the flipping of the rear flip door main body, and reducing the impact force when the rear flip door main body is flipped open.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a rear flip door structure of a drone with good load capacity, including a rear flip door frame 1 and a rear flip door main body 101. One side of the rear flip door frame 1 is movably connected to the rear flip door main body 101 through a hinge 103. Sealing strips 1011 are respectively fixed on the inner side of the rear flip door frame 1 and the outer side of the rear flip door main body 101. A torsion spring 104 is sleeved on the rotating shaft of the hinge 103. Connecting plates 102 are respectively fixed on the outer sides of the rear flip door frame 1 and the rear flip door main body 101. A connecting layer 2 is inlaid on one side of the rear flip door main body 101 close to the rear flip door frame 1, and a pattern aluminum plate 201 is fixed on the outer side of the connecting layer 2. A reinforcing frame 202 is inlaid on one side of the rear flip door main body 101 away from the pattern aluminum plate 201. One side of the connecting plate 102 is slidably butted with a docking rod 3 through a rotating shaft. One end of the docking rod 3 is sleeved with a docking pipe 301. One end of the docking rod 3 is sleeved with a first spring 302, and both ends of the first spring 302 are fixed to the docking rod 3 and the docking pipe 301 respectively. The outer side of the docking pipe 301 is fixed to one end of a second spring 303, and the other end of the second spring 303 is connected to the connecting plate 102. The connecting layer 2 is made of a plate pressed from wood fibers, and the docking rod 3 matches the docking pipe 301.

[0024] During specific implementation, according to Figures 1-5 , the drone can ensure stable flight and accurate target arrival through the flight control system, and is suitable for long-distance or tasks that require fixed-point delivery. When the drone transports materials to the target location, it is necessary to flip open the rear flip door main body 101, so that the rear flip door main body 101 pulls the docking rod 3, causing the docking rod 3 to drive the docking pipe 301 to rotate and open, and the docking pipe 301 pulls the second spring 303 to extend. When the rotation angle of the docking pipe 301 is greater than 90 degrees, the rear flip door main body 101 pulls the docking rod 3 to slide along the inner side of the docking pipe 301, causing the first spring 302 to contract. At the same time, the rear flip door main body 101 squeezes the torsion spring 104, so that one side of the rear flip door main body 101 is placed on the ground. When the staff steps on the rear flip door main body 101 to take out the materials, due to the plate made of wood fibers pressed in the connecting layer 2 having certain strength and stability, and the pattern aluminum plate 201 not only ensures anti-slip but also strengthens the strength of the rear flip door main body 101, and the fixed reinforcing frame 202 can further prevent the rear flip door main body 101 from deforming. When the rear flip door main body 101 is recovered, the torsion spring 104, the first spring 302 and the second spring 303 return to their deformed states at the same time, so that the torsion spring 104, the first spring 302 and the second spring 303 can reduce part of the weight of the rear flip door main body 101, making it easier to recover the rear flip door main body 101. And the sealing strip 1011 can keep the rear flip door frame 1 and the rear flip door main body 101 waterproof and sealed. Through the installation of the pattern aluminum plate 201 and the reinforcing frame 202, the rear flip door main body 101 can improve the structural strength and enhance the load capacity of the rear flip door main body 101.

[0025] Please refer to Figure 1 and Figure 6 , on one side of the rear flip door main body 101 close to the reinforcing frame 202, a fixed pipe 4 is connected. The fixed pipe 4 is slidably docked with a sliding frame 401. The sliding frame 401 is docked with a third spring 402. The two ends of the third spring 402 are respectively fixed to the fixed pipe 4 and the sliding frame 401. The lower end of the sliding frame 401 is docked with a connecting pad 403. A fixing ring 404 is inlaid on the outer side of the connecting pad 403. The connecting pad 403 is made of rubber material, and the connecting pad 403 is pressed against the sliding frame 401.

[0026] During specific implementation, according to Figure 1 and Figure 6 , when the rear flip door main body 101 rotates and opens close to the ground, first sleeve the connecting pad 403 with the sliding frame 401. Since the connecting pad 403 is made of rubber material and has a certain deformation ability, and the connecting pad 403 is pressed against the sliding frame 401, the connecting pad 403 and the sliding frame 401 are restricted together. The rear flip door main body 101 drives the connecting pad 403 to fit with the ground. Since the connecting pad 403 is made of rubber material and has a certain deformation ability, the connecting pad 403 can buffer the impact force on the ground when the rear flip door main body 101 flips. At this time, the sliding frame 401 slides along the fixed pipe 4 under force, and the sliding frame 401 pulls the third spring 402, so that the impact force generated by the flipping of the rear flip door main body 101 is further buffered, and the impact force can be reduced when the rear flip door main body 101 flips and opens.

[0027] In summary, the drone can ensure stable flight and accurate target arrival through the flight control system, and is suitable for long-distance or fixed-point delivery tasks. After the drone transports materials to the target location, it is necessary to rotate and open the rear flip door main body 101. When the staff steps on the rear flip door main body 101 to take out the materials, the patterned aluminum plate 201 ensures anti-slip while also strengthening the strength of the rear flip door main body 101. And the fixed reinforcing frame 202 can further prevent the rear flip door main body 101 from deforming and enhance the load-bearing capacity of the rear flip door main body 101. When the rear flip door main body 101 rotates and opens close to the ground, first sleeve the connecting pad 403 with the sliding frame 401 to restrict the connecting pad 403 and the sliding frame 401 together, so that the impact force generated by the flipping of the rear flip door main body 101 is further buffered, and the impact force can be reduced when the rear flip door main body 101 flips and opens. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
