Description

Technical Field

[0001] The present application relates to the field of drones, and more specifically, to a drone takeoff platform. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] For heavier drones, a vehicle-mounted takeoff platform is usually used to assist in takeoff, landing and transportation. The drone takeoff platform in related technologies is usually designed with a lifting mechanism inside a truck to drive the landing platform on the top to move to the top of the truck bed; or the landing platform is directly designed on the top of the vehicle, so that the drone can take off, land and be transported without obstacles.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] The landing platform in the above scheme is usually designed with a fixed buckle at a fixed position to lock the landing gear of the drone landing on the landing platform, and the locking process requires manual assistance, which is troublesome to operate. Utility Model Content

[0006] In order to make up for the above shortcomings, the present application provides a drone take-off platform, which is convenient for automatically unlocking the drone when it moves out of the truck bed, and automatically locking the drone landing gear when it moves into the truck bed, thereby improving the operational convenience.

[0007] The present application provides a drone take-off platform, including a bottom plate arranged inside a truck bed, a lifting member arranged on the bottom plate, a landing platform arranged through the lifting member, and a drone automatic locking member.

[0008] The automatic locking component of the drone includes bearing seats arranged at both ends of one side of the landing platform, and the two bearing seats are commonly connected to a bidirectional screw. The bidirectional screw is provided with a gear near the end, and a rack matched with the gear is provided on the bottom plate. Nut seats that are slidably connected to the landing platform are provided in different thread directions of the bidirectional screw, and push rods are provided on the nut seats, and pressure rods for tightening the drone landing gear are provided on both sides of the push rod.

[0009] Preferably, the lifting component includes two groups of connecting rods A and connecting rods B which are cross-designed and hinged together at the center connection. The top and bottom ends of the connecting rods A and B are respectively slidably hinged to the bottom end surface of the landing platform and the upper surface of the base plate. A connecting rod C is fixed between the upper parts of adjacent connecting rods A, and an electric push rod is hinged between the connecting rod C and the upper surface of the base plate.

[0010] Preferably, a side edge of the landing platform is provided with an escape opening for allowing the rack to pass through.

[0011] Preferably, a slider is fixed to the bottom of the nut seat, and a slide rail matching the slider is provided on the upper surface of the landing platform near one side thereof.

[0012] Preferably, when the landing platform is raised, the two push rods move away from each other, and vice versa.

[0013] Preferably, the pressure rod is designed in an L-shape to tighten the drone landing gear, and the pressure rod is detachably fixed to the push rod.

[0014] Preferably, the landing platform is flush with the top of the truck bed after being raised.

[0015] Beneficial effects: The present application provides a UAV take-off platform. When the UAV needs to take off, the lifting component is used to control the landing platform to move up. At the same time, the two-way lead screw is rotated counterclockwise by means of the cooperation of the gear and the rack, so that the nut seat is translated toward the separated direction. Therefore, when the landing platform moves to the top of the truck bed, the pressure rod just disengages from the UAV landing gear, which is convenient for the UAV to be quickly unlocked and take off; when the UAV needs to land, the lifting component is used to control the landing platform to move down. At the same time, the two-way lead screw is rotated clockwise by means of the cooperation of the gear and the rack, so that the nut seat is translated toward the relative direction. Therefore, the pressure rod can just slowly lock the UAV landing gear until it is locked, which is convenient for the UAV to be quickly locked when landing, and reduces the situation where the UAV is damaged due to bumps during transportation.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] See also Figure 1-Figure 2 , Figure 3 , Figure 5-Figure 6 The present application provides a drone take-off platform, including a bottom plate 1 arranged inside a truck bed, a lifting member 2 is arranged on the bottom plate 1, and a landing platform 3 is arranged through the lifting member 2, and also includes a drone automatic locking member 4,

[0026] The automatic locking component 4 of the drone includes bearing seats 41 arranged on both ends of one side of the landing platform 3. The two bearing seats 41 are commonly connected with a bidirectional screw 42. The bidirectional screw 42 is provided with a gear 47 near the end. A rack 43 adapted to the gear 47 is provided on the base plate 1. Nut seats 44 slidingly connected with the landing platform 3 are provided on different thread directions of the bidirectional screw 42. Push rods 45 are provided on the nut seats 44. Pressure rods 46 for tightening the drone landing gear are provided on both sides of the push rods 45.

[0027] In this embodiment, when the UAV needs to take off, the lifting component 2 is used to control the landing platform 3 to move up. At the same time, the two-way screw 42 is rotated counterclockwise by means of the cooperation of the gear 47 and the rack 43, so that the nut seat 44 is translated toward the separated direction. Therefore, when the landing platform 3 moves to the top of the truck bed, the pressure rod 46 just disengages from the UAV landing gear, which is convenient for the UAV to quickly unlock and take off; when the UAV needs to land, the lifting component 2 is used to control the landing platform 3 to move down. At the same time, the two-way screw 42 is rotated clockwise by means of the cooperation of the gear 47 and the rack 43, so that the nut seat 44 is translated toward the relative direction. Therefore, the pressure rod 46 can just slowly lock the UAV landing gear until it is locked, which is convenient for the UAV to be quickly locked when landing, and reduces the situation where the UAV is damaged due to bumps during transportation.

[0028] It should also be noted that both ends of the bidirectional lead screw 42 and the outer circumference at the installation location of the gear 47 are smooth sections, which facilitates the installation and fixation of the bidirectional lead screw 42 with the inner ring of the bearing seat 41 and the gear 47.

[0029] See also Figure 1 , Figure 3 The lifting member 2 includes two groups of connecting rods A21 and B22 which are cross-designed and hinged together at the center connection. The top and bottom ends of the connecting rods A21 and B22 are respectively slidably hinged with the bottom end surface of the landing platform 3 and the upper surface of the bottom plate 1. A connecting rod C23 is fixed between the upper parts of adjacent connecting rods A21, and an electric push rod 24 is hinged between the connecting rod C23 and the upper surface of the bottom plate 1. Specifically, when the piston end of the electric push rod 24 is extended, the lateral angle between the connecting rod A21 and the connecting rod B22 becomes larger, and the position of the landing platform 3 is raised to a state flush with the top of the truck bucket; when the piston end of the electric push rod 24 is retracted, the lateral angle between the connecting rod A21 and the connecting rod B22 becomes smaller, so that the landing platform 3 is retracted to the inside of the truck bucket. In this way, in addition to the locking structure, a second barrier of the truck bucket is added to the drone, which improves the stability of the drone transportation.

[0030] It should also be noted that both ends of the connecting rod A21 and the connecting rod B22 are fixed as follows Figure 3 As shown in the sliding hinge seat, the bottom end surface of the landing platform 3 and the upper surface of the bottom plate 1 are all provided with a slideway (not shown) adapted to the sliding hinge seat.

[0031] See also Figure 1-Figure 2 , Figure 4 The side of the landing platform 3 is provided with an escape opening 31 for the rack 43 to pass through. Specifically, the design of the escape opening 31 is convenient for providing a position for the rack 43 to be installed, so that the rack 43 can achieve meshing transmission with the gear 47.

[0032] See also Figure 4A slider 48 is fixed to the bottom of the nut seat 44, and a slide rail 32 adapted to the slider 48 is provided on the upper surface of the landing platform 3 near one side thereof. Specifically, the cooperation between the slider 48 and the slide rail 32 facilitates the stable translation of the nut seat 44, and indirectly achieves the stable translation of the pressure rod 46, which is conducive to locking the landing gear of the drone.

[0033] When the landing platform 3 is raised, the two push rods 45 move away from each other, and vice versa.

[0034] See also Figure 4 The pressure rod 46 is designed in an L shape to press the drone landing gear, and the pressure rod 46 is detachably fixed to the push rod 45. Specifically, the design of the pressure rod 46 allows the two push rods 45 to move in opposite directions to the top of the drone landing gear to lock it, and the pressure rod 46 can be installed on the push rod 45 by screw fixation, so that the position of the pressure rod 46 can be adjusted conveniently to adapt to the position locking of drone landing gears of different shapes.

[0035] After the landing platform 3 is raised, it is flush with the top of the truck bucket.

[0036] When using this application:

[0037] When the drone needs to take off, the electric push rod 24 is controlled to extend. At this time, the lateral angle between the connecting rod A21 and the connecting rod B22 becomes larger, so that the landing platform 3 moves up. At the same time, with the help of the cooperation of the gear 47 and the rack 43, the two-way screw 42 rotates counterclockwise, so that the nut seat 44 translates toward the separated direction. Therefore, when the landing platform 3 moves to the top of the truck bed, the pressure rod 46 just disengages from the drone landing gear, which is convenient for the drone to quickly unlock and take off; when the drone needs to land, the electric push rod 24 is controlled to retract. At this time, the lateral angle between the connecting rod A21 and the connecting rod B22 becomes smaller, so that the landing platform 3 is retracted to the inside of the truck bed. At the same time, with the help of the cooperation of the gear 47 and the rack 43, the two-way screw 42 rotates clockwise, so that the nut seat 44 translates toward the relative direction, so that the pressure rod 46 can just slowly lock the drone landing gear until it is locked, which is convenient for the drone to be quickly locked when landing, and reduces the situation where the drone is damaged due to bumps during transportation.
