Detailed implementation manners

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. In addition, it should be noted that for the sake of description, only parts related to the invention are shown in the drawings.

[0025] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] In addition, it should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] Please refer to Figure 1 and Figure 2 , the present invention provides a UAV transfer rack including a support frame, which is characterized in that it further includes a fixing mechanism. The support frame includes a loading position, and the fixing mechanism is arranged around the loading position. After the UAV is vertically loaded in the loading position, it can be fixed to the support frame through the fixing mechanism.

[0028] It should be noted that for the UAV transfer rack provided by the embodiment of the present invention, the UAV is vertically fixed on the UAV transfer rack through the loading position and the fixing structure. As Figure 6 shown, compared with the method of horizontally fixing the UAV, in combination with the disadvantage of the large size of the UAV in the horizontal direction, the design concept selects to vertically fix the UAV, fully occupying the upper space and improving the space utilization rate. While meeting the convenient loading of the UAV, it also greatly weakens the disadvantages of UAV transportation, reduces the transportation cost, increases the weight loaded per unit carriage, and at the same time can avoid the inconvenience caused during the maintenance of the UAV on the ground.

[0029] The following will make a detailed description of the specific structure and specific technical effects of the UAV transfer rack provided by the embodiment of the present invention:

[0030] In a specific structure, the fixing mechanism includes a wall-mounted cover plate 4. The wall-mounted cover plate 4 includes a first end and a second end that are opposite to each other. The first end is hinged to the support frame, and the second end is detachably connected to the support frame.

[0031] It should be noted that the first end of the hanging arm cover plate is hinged to the support frame, which can realize the up-and-down rotation of the hanging arm cover plate. See Figure 1 and Figure 2 , the second end of the hanging arm cover plate is connected to the support frame in a detachable manner. For example, by using a buckle lock, the buckle lock can load the drone conveniently and quickly, and can be used repeatedly with high stability. In addition to using the buckle lock method, bolt connection or hinge can also be used to connect the second end of the hanging arm cover plate to the support frame.

[0032] Please refer to Figure 3 , in a specific structure, a drone bearing seat 1 is arranged below the loading position. The drone bearing seat 1 includes a support plate. The first end is hinged to the support plate. The first end includes a bent portion, and the bent portion and the support plate form a first robotic arm limiting mechanism.

[0033] It should be noted that the first end of the hanging arm cover plate includes a bent portion. The 90-degree bent portion and the support plate of the drone bearing seat form a first robotic arm limiting structure, which cleverly fixes the landing gear of the drone here. A buffer material is arranged in the first mechanical limiting structure. When the vehicle encounters a bumpy section during transportation, it causes the drone transfer rack to tremble, and the buffer material can absorb the tremble to avoid damage to the drone.

[0034] Please refer to Figure 4 , in a specific structure, at least one second robotic arm limiting mechanism is further arranged between the first end and the second end.

[0035] It should be noted that when the second robotic arm limiting mechanism cooperates with a certain part of the drone, the cooperation method can be clearance fit, transition fit or interference fit. The second robotic arm limiting mechanism and the first robotic arm limiting mechanism fix the drone at a total of 4 points. Coupled with the two drone bearing seats fixing the drone, it is safer and more stable.

[0036] In a specific structure, the second robotic arm limiting mechanism includes a buffer material.

[0037] It should be noted that the second robotic arm limiting mechanism includes a buffer material, and its function is the same as that of the buffer material of the first robotic arm limiting structure.

[0038] Please refer to Figure 1, in a specific structure, the support frame includes two vertical rods 10 and two cross rods 6. Two of the drone carriers 1 are correspondingly arranged on the two cross rods 6 and are on the same side of the plane where the two vertical rods 10 are located.

[0039] Specifically, the support frame includes a first vertical rod and a second vertical rod, and the first vertical rod and the second vertical rod are perpendicularly and fixedly connected to the base.

[0040] The support frame further includes a first cross rod and a second cross rod. The first cross rod is perpendicularly fixed on the first vertical rod, and the connection between the first cross rod and the first vertical rod is in a cross shape. The second cross rod is perpendicularly fixed on the second vertical rod, and the connection between the second cross rod and the second vertical rod is in a cross shape.

[0041] The drone carrier includes a first drone carrier and a second drone carrier. The hanging arm cover plate includes a first hanging arm cover plate and a second hanging arm cover plate. The first drone carrier is fixedly connected to the first cross rod, the second drone carrier is fixedly connected to the second cross rod. The first end of the first hanging arm cover plate is hinged to the support plate of the first drone carrier, and the first end of the second hanging arm cover plate is hinged to the support plate of the second drone carrier.

[0042] The support frame further includes diagonal braces 9. The first vertical rod 10 and the base 11 are fixedly connected in a V shape by the two diagonal braces 9, and the second vertical rod 10 and the base 11 are fixedly connected in a V shape by the two diagonal braces 9. The diagonal braces 9 strengthen the stiffness of the entire support frame and ensure the safety of the drone.

[0043] The connections between the vertical rods and the cross rods are all by threaded connections, which facilitates the disassembly and assembly of the drone transfer rack.

[0044] In a specific structure, the support frame further includes a reinforcing plate 5. The cross rods 6 extend outward along the plane where the two vertical rods 10 are located, and the extending ends of the two cross rods 6 are fixedly connected by the reinforcing plate 5. The reinforcing plate 5 includes an assembly table or a maintenance table.

[0045] It should be noted that the reinforcing plate connects the two cross rods to improve the stability of the drone transfer rack. At the same time, the reinforcing plate can be used as an assembly table or a maintenance table for the drone, which improves the working efficiency of workers and reduces the labor intensity of workers.

[0046] In a specific structure, the support frame further includes a collision prevention rod 7. The collision prevention rod 7 is fixedly connected to the connection position between the vertical rod 10 and the cross rod 6, and the free end of the collision prevention rod 7 extends towards the outside of the support frame.

[0047] It should be noted that the collision prevention rod can be a single collision prevention rod (such as Figure 1(as shown), or it can also be two anti-collision bars. When the anti-collision bars are two anti-collision bars, the first ends of the two anti-collision bars are at the shown connection positions, and the second ends of the anti-collision bars are on the outer sides of the support frames. Function of the anti-collision bars: When the drone or the drone transfer rack is about to collide with the inner wall of the carriage, the anti-collision bars first come into contact with the inner wall of the carriage, preventing the drone or the drone transfer rack from hitting the inner wall of the carriage, thereby avoiding external force damage to the drone.

[0048] In a specific structure, the drone transfer rack further includes a displacement device, and the two vertical rods 10 are fixedly connected to the displacement device.

[0049] The displacement device includes a braking mechanism.

[0050] It should be noted that four universal wheels 12 are installed under the base 11, which are respectively located at the four corners of the base 11. Two of the front row or the rear row are universal wheels 12 with braking devices, and the remaining two are ordinary universal wheels 12.

[0051] When the drone transfer rack is loaded with drones, push the drone transfer rack to the freight car compartment and place it in a suitable position to make the universal wheels with braking devices in a braking state; when installing the drone transfer rack or repairing the drone, adjust the attitude of the drone transfer rack through the universal wheels to facilitate the workers' repair. The universal wheel structure not only reduces the labor intensity of the workers, but also improves the efficiency of the workers in repairing the drone, and at the same time avoids the artificial damage to the drone caused by flipping during the repair of the drone.

[0052] In summary, the drone transfer rack provided by the embodiment of the present invention, through the hanging arm cover plate, the drone bearing seat and the buckle lock, on the one hand, can conveniently load the drone, and on the other hand, vertically fix the drone, making full use of the upper space. Compared with the horizontal loading method, the space utilization rate of the drone transportation device is greatly improved, and the transportation cost is reduced. During transportation, the drone transfer rack considers various situations on how to ensure the safety of the drone. The drone transfer rack solves the safety problems of loading and transportation, and most of the parts of the drone transfer rack are processed by sheet metal parts, and the fixing method between the parts is also bolt fastening, which is convenient for assembly and forming. The structure of the entire drone transfer rack is simple, with a high degree of standardization and low manufacturing cost. Obviously, the drone transfer rack provided by the embodiment of the present invention will surely bring good market prospects and economic benefits.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
