Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted flight deck equipment, and in particular to a fast and portable mechanically connected deck hem structure. Background Art

[0002] Unmanned aerial vehicles (UAVs) are increasingly used in military, civilian, and commercial applications, and their takeoff and landing have always been a hot topic. To address this issue, a reconfigurable vehicle-mounted flight deck system has been designed. It consists of four modules with similar structures. These modules can be connected end to end to form a tunnel approximately 44 meters long and 14 meters wide, providing the necessary support and assurance for UAV takeoff and landing.

[0003] The system consists of multiple modules that can be combined and reconfigured according to specific needs. This means the flight deck's shape and size can be flexibly adjusted to suit different sites and mission requirements, accommodating the takeoff and landing of drones of varying models and sizes. By connecting the modules end-to-end to form a long, narrow channel structure, this facilitates precise drone takeoff and landing. This structure reduces interference from external environmental factors on drone takeoff and landing operations, improving safety and stability.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the cross-sectional height space of the reconfigurable vehicle-mounted flight deck system is limited. After the front and rear decks are docked, the connection mechanism between the rear deck and the front vehicle deck folding edge can easily affect the take-off and landing of the UAV, and can easily interfere with the chassis vehicle on the lower surface of the deck.

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] Unmanned aerial vehicles (UAVs) are increasingly used in military, civilian, and commercial applications, and their takeoff and landing have always been a hot topic. To address this issue, a reconfigurable vehicle-mounted flight deck system has been designed. It consists of four modules with similar structures. These modules can be connected end to end to form a tunnel approximately 44 meters long and 14 meters wide, providing the necessary support and assurance for UAV takeoff and landing.

[0028] The system consists of multiple modules that can be combined and reconfigured according to specific needs. This means the flight deck's shape and size can be flexibly adjusted to suit different sites and mission requirements, accommodating the takeoff and landing of drones of varying models and sizes. By connecting the modules end-to-end to form a long, narrow channel structure, this facilitates precise drone takeoff and landing. This structure reduces interference from external environmental factors on drone takeoff and landing operations, improving safety and stability.

[0029] Regarding the above-mentioned related technologies, the inventors believe that the cross-sectional height space of the reconfigurable vehicle-mounted flight deck system is limited. After the front and rear decks are docked, the connection mechanism between the rear deck and the front vehicle deck folding edge can easily affect the take-off and landing of the UAV, and can easily interfere with the chassis vehicle on the lower surface of the deck.

[0030] In order to improve the connection effect of the deck after the front and rear sides are docked and reduce the impact on the take-off and landing of the drone, the present application provides a fast and portable mechanical connection deck folding structure.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a fast portable mechanical connection deck hemming structure. Figure 1 、 Figure 2 A fast and portable mechanically connected deck folding structure includes a front deck 1, a rear deck 2 connected to form an integral deck is arranged on one side of the front deck 1, a folding deck 3 is arranged at the connection position of the front deck 1 and the rear deck 2, and one side of the folding deck 3 is hinged to the front deck 1, so that the connection gap between the front deck 1 and the rear deck 2 is blocked by the folding deck 3, so that the front deck 1, the rear deck 2 and the folding deck 3 form a complete deck for the take-off and landing of the drone.

[0033] A folding connection component 4 is provided on the side of the folding deck 3 close to the rear deck 2, and a rear deck connection component 5 is provided at a position opposite to the folding connection component 4 of the rear deck 2. The folding connection component 4 and the rear deck connection component 5 are overlapped with each other, thereby connecting the side of the folding deck 3 close to the rear deck 2 with the rear deck 2, and making the upper surface of the folding deck 3 flush with the upper surface of the reinforcement plate.

[0034] Reference Figure 2 、 Figure 3 and Figure 4 The hemming connection assembly 4 includes a square pin fixing seat 41. A receiving groove is horizontally defined on the side of the hemming deck 3 near the rear deck 2. The square pin fixing seat 41 is located inside the receiving groove and is fixedly connected to the hemming deck 3. The square pin fixing seat 41 is open on the side near the rear deck 2, and a first square pin 411 is fixedly connected inside the square pin fixing seat 41. A first overlapping portion 4111 is fixedly connected to the side of the first square pin 411 near the rear deck 2. A first inclined surface 4112 is defined at the bottom end of the first overlapping portion 4111. The first inclined surface 4112 is an inclined sidewall and is gradually inclined downward from the side away from the first square pin 411 to the side near the first square pin 411.

[0035] The rear deck 2 connection assembly includes a square pin guide seat 51. A second square pin 511 is horizontally positioned within the square pin guide seat 51, opposing the first square pin 411. A guide slot is horizontally defined within the square pin guide seat 51, extending along a line extending from the first square pin 411 to the second square pin 511. The second square pin 511 is positioned within the guide slot and slidably connected to the square pin guide seat 51, enabling the second square pin 511 to move within the guide slot toward or away from the first square pin 411.

[0036] A second overlapping portion 5111 is fixedly connected to the side of the second square pin 511 adjacent to the first square pin 411. A second inclined surface 5112 is defined on the upper surface of the second overlapping portion 5111. The second inclined surface 5112 is inclined in the same direction as the first inclined surface 4112. When the first and second square pins 411 and 511 are in contact with each other, the first inclined surface 4112 and the second inclined surface 5112 abut against each other, causing the first overlapping portion 4111 to overlap the second overlapping portion 5111.

[0037] The width of the first square pin 411 is greater than that of the second square pin 511 , thereby satisfying the range of the pin-cone surface connection under different working conditions and allowing the cone surface to better bear the load.

[0038] A drive assembly 52 is provided on the side of the second square pin 511 facing away from the first square pin 411 to drive the second square pin 511 within the guide groove. The drive assembly 52 includes a first connecting rod 521 hingedly connected to the second square pin 511. A second connecting rod 522 is hingedly connected to the side of the first connecting rod 521 facing away from the second square pin 511. A connecting rod support seat 523 is hingedly provided on the second connecting rod 522, which is fixedly connected to the rear deck 2. The second connecting rod 522 includes a connecting portion 5221 located on the side of the connecting rod support seat 523 near the first connecting rod 521. A push rod portion 5222 is fixedly connected to the connecting portion 5221 on the side of the connecting rod support seat 523 facing away from the first connecting rod 521. The push rod portion 5222 is arranged at an angle to the connecting portion 5221 and is tilted upward along the extension line of the connecting portion 5221.

[0039] The push rod portion 5222 includes a sleeve located inside the rear deck 2, and an inner rod is passed through the interior of the sleeve. The inner rod is inserted into the interior of the sleeve, and the top wall of the sleeve is not higher than the upper surface of the rear deck 2, so that when the push rod portion 5222 is driven to rotate, the inner rod is inserted into the interior of the sleeve, starting the push rod portion 5222 to rotate, and when the connection is completed, the inner rod is taken out from the interior of the sleeve, thereby reducing the protrusion from the surface of the rear deck 2.

[0040] An avoidance hole 21 is opened on the side wall of the rear deck 2 at a position relative to the push rod portion 5222 , and the push rod portion 5222 is located inside the avoidance hole 21 and is relatively slidably connected, and the end of the push rod portion 5222 extends from the surface of the rear deck 2 .

[0041] During the connection process, the operator can rotate the end of the push rod part 5222 to make the push rod part 5222 flip toward the end close to the first connecting rod 521, and the push rod part 5222 drives the connecting part 5221 to rotate in the same direction, and then the connecting part 5221 flips toward the side away from the first connecting rod 521, and the second square pin 511 moves toward the side away from the first square pin 411.

[0042] When the operator flips the end of the push rod part 5222 toward the side away from the first connecting rod 521, the push rod part 5222 drives the connecting part 5221 to rotate in the same direction, and then the connecting part 5221 flips toward the side close to the first connecting rod 521, and the second square pin 511 moves toward the side close to the first square pin 411.

[0043] Multiple sets of folding connection components 4 and rear deck 2 connection components are arranged between the folding deck 3 and the rear deck 2, and the spacing between two adjacent folding connection components 4 and rear deck 2 connection components is the same, and the first square pins 411 and the second square pins 511 inside the multiple sets of folding connection components 4 and rear deck 2 connection components are arranged opposite to each other, thereby providing stable support for the connection of the folding deck 3.
