Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) launch equipment technology, specifically a UAV launch device. Background Technology

[0002] With the rapid development of drone technology, large drones are being used more and more widely in fields such as reconnaissance, surveying and mapping, and material transportation. Due to their large size and weight, large drones place extremely high demands on the load-bearing capacity, transportability, leveling accuracy, and launch stability of the launch device.

[0003] For example, patent CN212766804U discloses a drone launching device, including a platform. A handle is fixedly connected to the surface of the platform, and a support upper seat is fixedly connected to the lower surface of the platform. A piston rod is slidably connected to the inner wall of the support upper seat, and a spring is sleeved on the support upper seat. A fixing plate is fixedly connected to the surface of the piston rod, and a hydraulic rod is fixedly connected to the bottom surface of the fixing plate. A support lower seat is fixedly connected to the output end of the hydraulic rod, and a moving wheel is provided at the end of the hydraulic rod away from the support upper seat.

[0004] However, existing devices lack built-in mobility, relying entirely on external large equipment for transport and deployment. This process is cumbersome and inefficient. The leveling system lacks precision, and the erection angle control is rough, making it difficult to guarantee a high-precision horizontal launch reference, which directly affects launch quality. The erection mechanism is not equipped with a reliable safety locking device, posing a risk of accidental overturning due to vibration or misoperation, resulting in significant safety hazards. Furthermore, when the UAV launch base's erection angle increases, the overall center of gravity of the device shifts upward and is affected by torque changes, leading to a significant decrease in system stability and making it prone to swaying or attitude deviation, which poses a potential risk to launch accuracy and operational safety.

[0005] Therefore, in order to solve this problem, we propose a drone launch device. Utility Model Content

[0006] The purpose of this utility model is to provide a drone launch device to solve the problems mentioned in the background art. These problems include the lack of built-in mobility of the platform, the complete reliance on external large equipment for transportation and deployment, cumbersome processes, low efficiency, insufficient accuracy of the leveling system, rough control of the erection angle, difficulty in ensuring a high-precision horizontal launch reference, which directly affects the launch quality, the lack of a reliable safety locking device for the erection mechanism, the risk of accidental overturning due to vibration or misoperation, which poses a significant safety hazard, and the fact that when the erection angle of the drone launch base increases, the overall center of gravity of the device shifts upward and is affected by changes in torque, resulting in a significant decrease in system stability, which is prone to swaying or attitude deviation, posing a potential risk to launch accuracy and operational safety.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drone launching device, including a base, with stoppers fixedly connected to the outer end of the top left side of the base, a hydraulic station fixedly connected to the middle of the top left side of the base, a horizontal sensor fixedly connected to the middle of the front and rear outer walls of the base, and support legs fixedly connected to the left side of the horizontal sensors on the front and rear outer walls of the base, a rectangular groove is provided on the base, and lower movable parts are fixedly connected to both sides of the inner wall of the right side of the rectangular groove, an erecting cylinder is fixedly connected to the lower movable part, an upper movable part is fixedly connected to the top of the erecting cylinder, a launching base is movably connected to the top of the upper movable part, and an angle encoder is fixedly connected to the middle of the top right side of the base, and the angle encoder is movably connected to the launching base.

[0008] Furthermore, a traction rod is fixedly connected to the left side of the base, and a sleeve is fixedly connected to the left side of the traction rod.

[0009] Furthermore, both ends of the bottom left side of the base are fixedly connected to casters, and the casters are equipped with brakes. Both ends of the bottom right side of the base are fixedly connected to rollers.

[0010] Furthermore, a guide rail is fixedly connected to the center of the top surface of the launch base, an adapter is fixedly connected to the left side of the top of the launch base, and binding tensioners are evenly fixedly connected to the right side of the adapter on the top of the base.

[0011] Furthermore, a truss is fixedly connected inside the launch base, and the UAV body is mounted on the top of the launch base, with guide rails adapted to the UAV body.

[0012] Furthermore, a pressure plate is fixedly connected to the right outer wall of the launch base, and side blocks are fixedly connected to both ends of the right outer wall of the base. A sliding rod is movably connected to the side block, a support plate is fixedly connected to the top of the sliding rod, and a pressure block is fixedly connected to the bottom of the sliding rod.

[0013] Furthermore, a spring is sleeved on the outer wall of the slide rod, and anti-slip protrusions are uniformly fixedly connected to the bottom of the pressure block, and the anti-slip protrusions are hemispherical in shape.

[0014] Compared with the prior art, the beneficial effects of this utility model are: a drone launching device adopts a novel structural design, the specific details of which are as follows:

[0015] (1) The UAV launcher has a tow bar fixedly connected to the left side of the base, and universal wheels are provided at both ends of the left side and rollers at both ends of the right side of the base. It does not rely on external large-scale transfer equipment. With the tow bar and universal wheels and rollers, it can move and turn quickly in the field, greatly simplifying the transfer process and improving deployment efficiency. It is especially suitable for scenarios that require frequent adjustment of the launch position. A level sensor is fixedly connected to the middle of the front and rear outer walls of the base, which can detect the levelness of the base in real time and transmit the signal to the hydraulic station at the middle of the left side of the top of the base. The base is connected to the erection cylinder through the lower movable part in the rectangular groove. The top of the erection cylinder is movably connected to the launch base through the upper movable part. Meanwhile, the angle encoder on the top right center of the base is movably connected to the launch base. The angle encoder can monitor the launch base's erection angle in real time and feed the signal back to the hydraulic station. The hydraulic station controls the extension and retraction of the erection cylinder to precisely control the launch base's erection angle, avoiding the impact of rough angle control on launch accuracy. A guide rail is provided in the center of the top surface of the launch base, and binding and tightening devices are evenly provided on the top of the base and the right side of the adapter. The binding and tightening devices can firmly fix the UAV body on the launch base, preventing the UAV from shifting due to vibration before launch. At the same time, the fixed truss inside the launch base enhances the overall structural strength of the base, improves the load-bearing capacity, and prevents the base from deforming and causing launch risks.

[0016] (2) The launch device of the UAV has a pressure plate fixedly connected to the outer wall of the right side of the launch base. Side blocks are provided at both ends of the outer wall of the right side of the base. A sliding rod is movably connected to the side block. The top of the sliding rod is connected to a support plate and the bottom is connected to a pressure block. When the launch base rises at an angle and the overall center of gravity moves upward, the launch base drives the pressure plate to deflect. The pressure plate squeezes the support plate, causing the sliding rod to slide downward along the side block, thereby pushing the pressure block to press against the ground. This structure increases the contact area between the device and the ground through the pressure block, and the anti-slip protrusion enhances the friction, effectively offsetting the unstable effects caused by the upward movement of the center of gravity and the change of torque, avoiding device shaking or attitude deviation, and ensuring operational safety and launch accuracy.

[0017] Furthermore, the stopper fixedly connected to the outer left side of the top of the base can limit and fix the launch base when it is in a horizontal storage state, preventing the launch base from moving unexpectedly due to vibration when the device is transported or idle.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: A drone launch device, using a traction rod 11 on the base 1 and omnidirectional wheels 14 at the bottom, enables rapid transport of the device within the site. After selecting the automatic leveling mode, the level sensor 15 detects the levelness of the base 1 in real time and transmits the signal to the hydraulic station 13. After leveling, the hydraulic station 13 drives two erecting cylinders 17 to extend, pushing the launch base 2 to rotate upward around the rotating structure. The angle encoder 18 monitors the erection angle of the launch base 2 in real time and feeds the angle signal back to the hydraulic station 13. This prevents the platform from lacking built-in mobility, relying entirely on external large equipment for transport and deployment, resulting in cumbersome processes, low efficiency, insufficient leveling system precision, and rough control of the erection angle, making it difficult to guarantee a high-precision horizontal launch reference, directly affecting launch quality. Furthermore, the erection mechanism is not equipped with a reliable safety locking device, posing a risk of accidental overturning due to vibration or misoperation, highlighting significant safety hazards.

[0027] like Figure 1 - Figure 5As shown, a drone launching device includes a base 1. A stopper 12 is fixedly connected to the outer end of the top left side of the base 1. A hydraulic station 13 is fixedly connected to the middle of the top left side of the base 1. This hydraulic station 13 can receive detection signals from a level sensor 15, automatically determine the tilt direction and degree of the base 1, and then drive the outriggers 16 to extend and retract. Simultaneously, it can supply oil to the erecting cylinder 17 to drive its extension. It can also receive data feedback from an angle encoder 18, and stop supplying oil to the erecting cylinder 17 when the launching base 2 reaches a preset angle. A level sensor 15 is fixedly connected to the middle of the front and rear outer walls of the base 1. After the device is started, the level sensor 15 can detect the horizontal state of the base 1 in real time and synchronously transmit the detection signal to the hydraulic station 13. Once the base 1 reaches the preset horizontal accuracy, the leveling process automatically stops. Support legs 16 are threaded onto both sides of the horizontal sensor 15 on the front and rear outer walls of the base 1. A rectangular slot is provided on the base 1, and lower movable parts are fixedly connected to both sides of the inner right wall of the rectangular slot. These lower movable parts connect the base 1 to the bottom of the erecting cylinder 17, providing a stable mounting base for the erecting cylinder 17 and ensuring that the erecting cylinder 17 can smoothly push the launching base 2 to rotate. The erecting cylinder 17 is fixedly connected to the lower movable part. After the hydraulic station 13 supplies oil, the erecting cylinder 17 extends. Since its bottom is connected to the inner right wall of the rectangular slot of the base 1 via the lower movable part, and its top is movably connected to the launching base 2 via the upper movable part, the extended erecting cylinder 17 can push the launching base 2 around the angle encoder. The cylinder 17 rotates upwards and maintains its current length after the hydraulic station 13 stops supplying oil, stabilizing the launch base 2 at the target angle. An upper movable component is fixedly connected to the top of the erecting cylinder 17, connecting the top of the cylinder 17 to the launch base 2. This, in conjunction with the lower movable component, enables a movable connection between the erecting cylinder 17 and the launch base 2, ensuring the launch base 2 can rotate flexibly. The launch base 2 is movably connected to the top of the upper movable component. Under the push of the erecting cylinder 17, the launch base 2 rotates upwards around the angle encoder 18, stabilizing after reaching the preset launch angle, providing a support platform for the UAV launch. Its top surface is used to place the UAV body 25. An angle encoder 18 is fixedly connected to the middle of the right side of the top of the base 1, and the angle encoder 18 is connected to the launch base. 2. The angle encoder 18 can collect the real-time erection angle data of the launch base 2 during its erection process and feed the data back to the hydraulic station 13, providing a basis for the hydraulic station 13 to determine whether to stop oil supply. A traction rod 11 is fixedly connected to the left side of the base 1, and a sleeve is fixedly connected to the left side of the traction rod 11. This sleeve can dock with external traction equipment to achieve traction movement of the device. Universal wheels 14 are fixedly connected to both ends of the left side of the bottom of the base 1. Brakes are installed on the universal wheels 14, which are responsible for flexible steering during device movement. When the device moves to the target launch position, locking the brakes completely fixes the device, completing the transfer and deployment. Rollers are fixedly connected to both ends of the right side of the bottom of the base 1.The roller assists in sliding during device movement, reducing resistance. A guide rail 21 is fixedly connected to the center of the top surface of the launch base 2. This guide rail 21 is adapted to the drone body 25 to ensure that the drone body 25 can be accurately placed on the launch base 2. An adapter 22 is fixedly connected to the left side of the top of the launch base 2. Binding tensioners 23 are evenly fixedly connected to the right side of the adapter 22 on the top of the base 1. After the drone body 25 is placed, the binding tensioners 23 can firmly fix the drone body 25 to the launch base 2 to prevent the drone from shifting during subsequent operations. A truss 24 is fixedly connected inside the launch base 2. This truss 24 is used to enhance the structural strength of the launch base 2 to ensure that the launch base 2 remains stable during the support of the drone body 25 and during erection. The drone body 25 is placed on the top of the launch base 2, and the guide rail 21 is adapted to the drone body 25. After the drone body 25 is placed on the launch base 2 and the launch base 2 is erected to the preset angle, it awaits launch.

[0028] Example 2: Unlike Example 1, when the launch base 2 is deflected, the pressure plate 3 is also deflected. Then, the support plate 34 and the slide rod 32 drive the pressure block 35 to move downward, thereby increasing the contact area between the overall device and the ground. This prevents the overall center of gravity of the device from shifting upward and being affected by torque changes when the UAV launch base 2 is erected at an increased angle. This would not lead to a significant decrease in system stability, making it prone to shaking or attitude deviation, which would pose a potential risk to launch accuracy and operational safety.

[0029] like Figure 6As shown, a pressure plate 3 is fixedly connected to the right outer wall of the launch base 2. During the erection of the launch base 2, the pressure plate 3 rotates synchronously with the base, gradually pressing the support plate 34 at the top of the slide rod 32. Side blocks 31 are fixedly connected to both ends of the right outer wall of the base 1 to provide movable support for the slide rod 32. The slide rod 32 is movably connected to the side block 31. Under the pressure of the pressure plate 3, it can move vertically downward along the side block 31. The top of the slide rod 32 is fixedly connected to the support plate 34 to receive the pressure of the pressure plate 3. A spring 33 is sleeved on the outer wall of the slide rod 32. A pressure block 35 is fixedly connected to the bottom of the slide rod 32. As the slide rod 32 moves downward, it can fit tightly against the ground to enhance the stability of the device. Anti-slip protrusions are evenly fixedly connected to the bottom of the pressure block 35. The anti-slip protrusions are hemispherical in shape, which increases the contact area between the device and the ground on the one hand, and on the other hand... To enhance friction with the ground, the overall center of gravity shifts upward when the launch base 2 is erected, thus ensuring the stability of the device's posture. After the launch base 2 stabilizes at the preset angle, the binding tensioner 23 on the right side of the top adapter 22 of the base 1 releases the fixing constraint on the UAV body 25. The UAV body 25 slides smoothly along the guide rail 21 in the middle of the top surface of the launch base 2, completing the launch action. After the launch, the hydraulic station 13 drives the erection cylinder 17 to retract. The erection cylinder 17 pulls the launch base 2 downward around the connection point between the angle encoder 18 and the base 1 through the upper movable part at the top, until the launch base 2 returns to a horizontal state. At this time, the stopper 12 fixed at the outer end of the top left of the base 1 limits and fixes the launch base 2 to prevent it from moving accidentally. The device enters standby mode, waiting for the next use.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
