[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 As shown, a drone launch channel includes a guide rail 1 and an ejection mechanism 4 mounted on the guide rail 1. A placement mechanism 5 is mounted on the ejection mechanism 4. An adjustment mechanism 2 is mounted on the bottom of the guide rail 1. The adjustment mechanism 2 includes a bracket 205. A fixing plate 208 is fixedly connected to the bottom of the bracket 205. A lead screw 206 is rotatably connected to the bracket 205 and the fixing plate 208. A sliding groove 202 is provided on the fixing plate 208. A slider 203 is slidably connected to the sliding groove 202. The slider 203 is threadedly connected to the lead screw 206. Two fixing seats 201 are fixedly connected to the bottom of the guide rail 1. Rotating plates 204 are rotatably connected to both sides of the slider 203 and the two fixing seats 201.

[0023] As a technical optimization of the present invention, the adjustment mechanism 2 further includes a rudder disk 207, and the end of the lead screw 206 is fixedly connected to the rudder disk 207, so as to adjust the position of the slider 203 by rotating the lead screw 206.

[0024] As a technical optimization of the present invention, the ejection mechanism 4 includes a sealing plate 410. The end of the guide rail 1 is fixedly connected to the sealing plate 410 by screws. A guide shaft 405 is fixedly connected between the sealing plate 410 and the guide rail 1. A launching block 407 is slidably connected to the guide shaft 405. The two sides of the launching block 407 are slidably connected to the guide rail 1. A spring 406 is clamped between the guide rail 1 and the launching block 407. Two sets of side plates 401 are fixedly connected to the bottom of the guide rail 1. A roller 402 is rotatably connected between the two opposing side plates 401. A conveyor belt 403 is installed between the two rollers 402. A control plate 409 is fixedly connected to the conveyor belt 403. The bottom of the launching block 407 is fixedly... A contact plate 408 is connected, which abuts against a control plate 409. A drive unit 404 is installed on the side wall of one of the side plates 401. The output end of the drive unit 404 is connected to one of the rollers 402 through a coupling. Activating the drive unit 404 causes the conveyor belt 403 to rotate. The control plate 409 then abuts against the contact plate 408. As the control plate 409 moves, it pushes the contact plate 408, causing the launch block 407 to move to the bottom of the guide rail 1. The spring 406 contracts, pressing and storing force on the launch block 407. When the control plate 409 passes the contact plate 408, the spring 406 resets, and the launch block 407 is ejected to provide thrust for the UAV, assisting in flight.

[0025] As a technical optimization of the present invention, the bottom of the contact plate 408 is arc-shaped and the top of the control plate 409 is arc-shaped, which facilitates the separation of the control plate 409 from the contact plate 408.

[0026] As a technical optimization of the present invention, the placement mechanism 5 includes an insertion hole 503. The top of the launching block 407 has an insertion hole 503. An insert plate 504 is inserted into the insertion hole 503. A screw 505 is inserted into the launching block 407. The screw 505 passes through the hole in the insert plate 504. A nut is threaded onto the screw 505. A placement platform 501 that abuts against the bottom of the launching block 407 is fixedly connected to the insert plate 504, so as to realize the installation and fixation of the placement platform 501 and facilitate the replacement of worktables of different shapes.

[0027] As a technical optimization of the present invention, the placement mechanism 5 also includes a rubber pad 502. The rubber pad 502 is bonded to the inner side of the placement platform 501. The cross-section of the placement platform 501 is a right-angled triangular structure. When the launch block 407 is ejected, it generates recoil force, and the drone can be buffered by the rubber pad 502 to avoid damage to the drone.

[0028] As a technical optimization of the present invention, four rectangular insert plates 504 are arranged, and screws 505 are inserted into the holes on two insert plates 504 on the same side to achieve more stable fixation of the placement platform 501.

[0029] As a technical optimization of the present invention, a protective mechanism 6 is installed on the guide rail 1. The protective mechanism 6 includes two slide rods 601. The two slide rods 601 are slidably connected to each other on the guide rail 1. The ends of the two slide rods 601 are welded with protective plates 602 opposite to the launching block 407. A second spring 603 is clamped between the protective plate 602 and the guide rail 1. A rubber block 604 is glued to the side wall of the protective plate 602. When the launching block 407 is ejected, it can collide with the protective plate 602. The second spring 603 is compressed, which can buffer the launching block 407 and prevent the launching block 407 from being damaged.

[0030] As a technical optimization of the present invention, the bottom of the fixed plate 208 is provided with a rotating mechanism 3, the rotating mechanism 3 includes a rotating seat 302, the bottom of the fixed plate 208 is fixedly connected to the rotating seat 302, the bottom of the rotating seat 302 is rotatably connected to the base plate 301, and the fixed plate 208 is threadedly connected to a stud 303 that abuts against the base plate 301. The rotating seat 302 can be rotated by rotating the fixed plate 208, and the fixed plate 208 can be fixed by the stud 303, so as to adjust the horizontal angle of the UAV launch.

[0031] In use, before launch, the horizontal angle of the launch channel is adjusted at the launch site according to the flight direction requirements of the UAV. The fixed plate 208 is rotated to make the rotating seat 302 rotate on the base plate 301. After adjusting to the appropriate angle, the stud 303 is tightened to ensure tight contact with the base plate 301, thereby fixing the fixed plate 208 and ensuring the launch channel is at the required horizontal angle. If the tilt angle of the guide rail 1 needs to be adjusted, the rudder disk 207 can be rotated to drive the lead screw 206. Since the slider 203 is threadedly connected to the lead screw 206 and slides on the groove 202, the rotation of the lead screw 206 will cause the slider 203 to move along the groove 202. When the slider 203 moves... The rotating plates 204 on both sides drive the guide rail 1 to rotate around the fixed base 201, thereby changing the tilt angle of the guide rail 1 to meet different launch angle requirements. Rotating the screw 206 clockwise increases the elevation angle of the guide rail 1, and vice versa, making it easy to quickly adjust the launch elevation angle. It also has a self-locking function to prevent recoil from changing the elevation angle, ensuring the accuracy of the next launch. According to the size and shape of the UAV, select a suitable placement platform 501, insert the insertion plate 504 into the insertion hole 503 on the top of the launch block 407, and ensure that the insertion plate 504 is installed in place. Then, the screw 505 passes through the hole on the insertion plate 504, and the nut is screwed on the screw 505 to make the placement platform 501 firmly installed on the launch block 407.To replace the placement platform 501, simply unscrew the nut, remove the screw 505, and pull out the insert plate 504 to replace it with a new one. Place the drone stably on the placement platform 501. The rubber pad 502 bonded to the inside of the placement platform 501 can act as a buffer when the launch block 407 launches the drone, preventing damage during ejection. Finally, start the drive unit 404, which is a motor. The output of the drive unit 404 drives one of the rollers 402 to rotate via a coupling. The movement of the control plate 409 on the conveyor belt 403 causes the conveyor belt 403 to rotate. When the control plate 409 contacts the contact plate 408 at the bottom of the launching block 407, the continued movement of the control plate 409 pushes the contact plate 408, causing the launching block 407 to move along the guide shaft 405 to the bottom of the guide rail 1. At the same time, the spring 406 clamped between the guide rail 1 and the launching block 407 contracts, thus pressing and storing force on the launching block 407. When the control plate 409 passes the contact plate 408, the pressure is released. After 08, the contact plate 408 separates from the control plate 409, the spring 406 resets, and the launch block 407 is ejected under the elastic force of the spring 406, providing thrust for the drone placed on the platform 501 and assisting in its flight. Since the bottom of the contact plate 408 and the top of the control plate 409 are both arc-shaped, it is easy for the control plate 409 to separate from the contact plate 408 quickly, ensuring a smooth launch process. After the launch block 407 is ejected, it will collide with the protective plate 602. The spring 603 clamped between the protective plate 602 and the guide rail 1 is compressed, which buffers the launch block 407 and prevents it from being damaged by the collision. At the same time, the rubber block 604 bonded to the side wall of the protective plate 602 can further absorb the impact force and enhance the buffering effect. After the launch block 407 stops moving, the drive component 404 can be started again to make the conveyor belt 403 rotate, the control plate 409 returns to the initial position, and the launch block 407 is compressed again, preparing for the next drone launch.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
