Description

Technical Field

[0001] This invention relates to the field of drone lighting equipment technology, and more particularly to a drone lighting lamp for stage scenes. Background Technology

[0002] In stage settings, drones equipped with lighting can carry high-brightness, adjustable light sources to achieve aerial mobile lighting, precise fill lighting, and light and shadow modeling. This provides flexible lighting support for stage performances, light shows, and celebratory events. Especially in outdoor settings where stage lighting cannot be suspended, drones carrying lighting equipment can switch light colors and brightness in sync with the performance rhythm, outlining the stage contours and highlighting the main performer. They can also work in conjunction with ground lighting to create immersive visual effects. This technology is suitable for various stage scenarios such as festivals, commercial launches, and cultural tourism performances, enriching the stage presentation, enhancing the technological feel and visual impact of the performance, and meeting the diverse lighting and artistic expression needs of the stage.

[0003] Currently, drone lighting for stage scenes generally uses a dual-motor control scheme for angle adjustment. One motor controls the yaw angle (the angle of use in the horizontal plane), and the other motor controls the pitch angle (the angle of use in the vertical plane). Dual motors require two additional sets of ESCs, drive modules, independent power supply harnesses, and mounting brackets, which is costly and significantly increases the overall weight of the lighting fixture. Drones, especially those used for stage operations, have limited payload capacity and are extremely sensitive to their own weight. The extra weight will significantly increase the power consumption of the drone during flight, resulting in insufficient battery life for stage lighting operations and failing to meet the lighting needs of long-duration stage performances, thus making them impractical. Summary of the Invention

[0004] This invention relates to a drone lighting system for stage scenes. It includes a lighting component that can be mounted on the bottom of the drone to provide stage lighting. With the cooperation of a yaw and pitch mechanism, it can achieve single-motor control of the yaw and pitch angles of the lighting fixture. This eliminates the traditional dual-motor drive structure used in drone stage lighting equipment, significantly reducing the weight and space occupied by components such as drive motors, electrical control harnesses, and transmission brackets. In actual drone operation, it significantly reduces the overall load and flight power consumption, effectively improving the drone's endurance and hovering stability. Simultaneously, it simplifies the overall transmission structure and control logic, reducing usage and production costs, minimizing potential malfunctions caused by multi-motor coordinated control, and enhancing the equipment's vibration resistance and operational reliability in drone flight vibration environments. It can stably achieve the unidirectional yaw rotation and reciprocating pitch sweeping lighting effects required for stage lighting, precisely adapting to the operational needs of ambient lighting and dynamic light and shadow rendering in stage scenes. It balances the lightweight design of the drone mounting equipment with the practicality of lighting angle adjustment, making it highly practical.

[0007] Furthermore, a time-sharing block is radially inserted into the interior of both the yaw drive shaft and the pitch drive shaft. The time-sharing block is equipped with a positioning top spring, and the two ends of the positioning top spring abut against the interior of the time-sharing block and the corresponding shaft body, respectively.

[0008] Furthermore, both the yaw gear and the pitch gear have time-sharing grooves inside, and the two time-sharing blocks are respectively inserted into the two time-sharing grooves.

[0009] Furthermore, the time-sharing block and the time-sharing tooth groove together form a drive mechanism. The cross-sectional shape of the outer block of the time-sharing block and the cross-sectional shape of a single tooth groove of the time-sharing tooth groove are both right-angled triangles, and the rotation direction of the time-sharing block and the straight edge of the time-sharing tooth groove of the two drive mechanisms is the same when they are engaged.

With the cooperation of the yaw and pitch mechanisms, it can achieve single-motor control of the yaw and pitch angles of the lighting, eliminating the traditional structure of dual-motor separate drive control in drone stage lighting equipment.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0030] Please refer to Figures 1 to 11 Example 1: This invention proposes a drone lighting system for stage scenes, comprising: a drone body 1, with a lighting component located at the bottom of the drone body 1; the lighting component consists of a mounting mechanism 2, a yaw mechanism 3, and a pitch mechanism 4; Mounting mechanism 2 includes a fixed base 201, a rotating base 202, a lighting fixture 203, and a control motor 204. The fixed base 201 is fixedly mounted on the bottom of the UAV body 1, and the rotating base 202 has a "U"-shaped structure. The rotating base 202 is rotatably connected to the bottom of the fixed base 201, and there is a certain resistance when the rotating base 202 rotates at the bottom of the fixed base 201. After the yaw is adjusted to the correct position, it can autonomously position itself without inertial deviation. The control motor 204 is fixedly mounted on the side of the rotating base 202, and a lighting lamp is installed inside the lighting fixture 203. The yaw mechanism 3 includes a yaw gear 301 and a yaw drive shaft 3. 02. The yaw gear 301 is rotatably connected to the inside of the rotating base 202, and the yaw drive shaft 302 is rotatably connected to the inside of the rotating base 202; the pitch mechanism 4 includes a pitch gear 401, a pitch drive shaft 402, a drive disk 403, and a reciprocating frame 404. The pitch mechanism 4 and the yaw mechanism 3 are symmetrically arranged on both sides of the control motor 204. The pitch gear 401 is rotatably connected to the inside of the rotating base 202, the pitch drive shaft 402 is rotatably connected to the inside of the rotating base 202, the drive disk 403 is rotatably connected to the inside of the rotating base 202, and the reciprocating frame 404 is inserted into the inside of the rotating base 202.

[0031] The control motor 204 has a drive gear 2041 on its external shaft. The top and bottom of the drive gear 2041 mesh with the teeth of the yaw gear 301 and the pitch gear 401, respectively. The yaw gear 301, the yaw drive shaft 302, the pitch gear 401 and the pitch drive shaft 402 are on the same rotation axis. In use, the UAV body 1 can carry a lighting component and take off to provide the required lighting effects for the stage scene. The lighting component adopts a single motor drive control structure. By controlling the forward and reverse rotation of the control motor 204, the yaw angle and pitch angle of the lighting can be controlled respectively. It is easy to use, ensures that the lighting direction meets the actual needs, and has strong flexibility and adaptability.

[0032] In this design, a time-sharing block 3021 is radially inserted into the interior of both the yaw drive shaft 302 and the pitch drive shaft 402. The time-sharing block 3021 has a positioning spring 3022 inside, with its two ends abutting against the interior of the time-sharing block 3021 and the corresponding shaft. Both the yaw gear 301 and the pitch gear 401 have time-sharing tooth grooves 4011 inside. The two time-sharing blocks 3021 are respectively inserted into the interior of the two time-sharing tooth grooves 4011. The time-sharing blocks 3021 and the time-sharing tooth grooves 4011 together form the drive mechanism. The outer side of the time-sharing block 3021... The cross-sectional shape of the body and the individual tooth groove of the time-sharing gear 4011 are both right-angled triangles. Furthermore, the rotation directions of the time-sharing locking block 3021 and the straight edge of the tooth groove of the time-sharing gear 4011 when engaged are the same. In use, when it is necessary to adjust the yaw angle of the lighting lamp, this can be achieved by adjusting the forward rotation of the motor 204. When the motor 204 rotates forward, it synchronously drives the yaw gear 301 and the pitch gear 401 to rotate, and the rotation directions of the yaw gear 301 and the pitch gear 401 are opposite. When the motor 204 rotates forward, the internal drive mechanism of the yaw mechanism 3... The time-sharing locking block 3021 and the time-sharing tooth groove 4011 are engaged by their straight edges, meaning the yaw gear 301 drives the yaw drive shaft 302 to rotate synchronously. A positioning gear 3023 is located at the top of the yaw drive shaft 302, and a positioning tooth ring 2011 is located inside the fixed base 201. The positioning gear 3023 and the positioning tooth ring 2011 mesh and transmit power. When the yaw drive shaft 302 rotates, the positioning gear 3023 can drive the rotating base 202 to rotate via the positioning tooth ring 2011. When the rotating base 202 rotates, it can drive the lighting lamp holder 203 and the lighting lamps inside it to rotate. The movement of the motor 204 changes the yaw angle of the lighting lamp, and the rotating base 202 can continuously rotate in one direction, which can meet the function of positioning at any angle within 360 degrees. The adjustment is convenient and flexible. At the same time, the time-sharing block 3021 and the tooth groove inclined edge of the time-sharing tooth groove 4011 of the internal drive mechanism of the pitch mechanism 4 abut and squeeze each other, so that the time-sharing block 3021 retracts into the pitch drive shaft 402 to avoid the rotation of the pitch gear 401 and compress the positioning top spring 3022. Thus, the motor 204 does not change the pitch angle of the lighting lamp when rotating in the forward direction, and the operation is stable.

[0033] The pitch drive shaft 402 has a drive worm gear 4021 at its bottom, and a positioning worm wheel 4031 is provided on the side of the drive disc 403. The drive worm gear 4021 and the positioning worm wheel 4031 are connected by a transmission. In use, when it is necessary to adjust the pitch angle of the lighting lamp, it can be achieved by rotating the motor 204 in the reverse direction. When the motor 204 rotates in the reverse direction, it will also drive the yaw gear 301 and the pitch gear 401 to rotate. At this time, the internal drive mechanism 4 of the pitch mechanism 4 is also engaged. The time-sharing locking block 3021 and the time-sharing gear groove 4011 are engaged by their straight edges, so that the pitch gear 401 can drive the pitch drive shaft 402 to rotate. When the pitch drive shaft 402 rotates, the drive worm 4021 can drive the drive disk 403 to rotate through the positioning worm wheel 4031. The other side of the drive disk 403 is provided with a positioning lever 4032, and the bottom of the reciprocating frame 404 is provided with a positioning groove 4041. The positioning lever 4032 is inserted into the positioning groove 4041. When the drive disc 403 rotates, the positioning slot 4041 can drive the reciprocating frame 404 to move up and down reciprocally via the positioning lever 4032. The top of the reciprocating frame 404 is provided with a reciprocating rack 4042, and the outside of the rotating shaft of the lighting fixture 203 is provided with a reciprocating gear 2031. The reciprocating gear 2031 and the reciprocating rack 4042 mesh and drive each other. When the reciprocating frame 404 moves up and down, the reciprocating rack 4042 can drive the lighting fixture 203 via the reciprocating gear 2031. The yaw mechanism reciprocates within a certain angle, thereby controlling the pitch angle of the lighting lamp. At the same time, the time-sharing block 3021 and the inclined edge of the tooth groove 4011 of the drive mechanism inside the yaw mechanism 3 abut and squeeze each other, causing the time-sharing block 3021 to retract into the pitch drive shaft 402 to avoid the rotation of the pitch gear 401 and compress the positioning top spring 3022. Thus, the motor 204 does not change the yaw angle of the lighting lamp when it rotates in the opposite direction, ensuring stable operation.

[0034] The specific usage and function of this embodiment: In this invention, the UAV body 1 can be equipped with a lighting component for aerial use, providing the required lighting effects for the stage scene. The lighting component adopts a single motor drive control structure. By controlling the forward and reverse rotation of the motor 204, the yaw angle and pitch angle of the lighting can be controlled respectively. When it is necessary to control the yaw angle of the lighting, it can be achieved by controlling the forward rotation of the motor 204. When the motor 204 is controlled to rotate forward, it can synchronously drive the yaw gear 301 and the pitch gear 401 to rotate, and the rotation directions of the yaw gear 301 and the pitch gear 401 are opposite. When the motor 204 is controlled to rotate forward, the time-sharing block 3021 and the straight edge of the tooth groove of the time-sharing tooth groove 4011 of the drive mechanism inside the yaw mechanism 3 are activated. The yaw gear 301 drives the yaw drive shaft 302 to rotate synchronously. When the yaw drive shaft 302 rotates, the positioning gear 3023 drives the rotating seat 202 to rotate via the positioning gear ring 2011. The rotating seat 202, in turn, drives the lighting fixture 203 and its internal lighting fixture to rotate, thereby changing the yaw angle of the lighting fixture. The rotating seat 202 can continuously rotate in one direction, satisfying the function of positioning at any angle within 360 degrees, with convenient and flexible adjustment. Simultaneously, the time-sharing locking block 3021 and the inclined edge of the time-sharing gear groove 4011 of the internal drive mechanism of the pitch mechanism 4 abut and press against each other, causing the time-sharing locking block 3021 to retract into the pitch drive shaft 402 to avoid the rotation of the pitch gear 401. The compression positioning spring 3022 ensures that the pitch angle of the lighting lamp is not changed when the motor 204 rotates in the forward direction. When the pitch angle needs to be adjusted, the motor 204 can be rotated in the reverse direction. When the motor 204 rotates in the reverse direction, it will also drive the yaw gear 301 and the pitch gear 401 to rotate. At this time, the time-sharing block 3021 of the drive mechanism inside the pitch mechanism 4 and the straight edge of the time-sharing tooth groove 4011 are engaged, so that the pitch gear 401 can drive the pitch transmission shaft 402 to rotate. When the pitch transmission shaft 402 rotates, the drive worm 4021 can drive the drive disk 403 to rotate through the positioning worm wheel 4031. When the drive disk 403 rotates, the positioning slot 4041 can drive the positioning lever 4032 to rotate. The reciprocating frame 404 moves up and down repeatedly. During this movement, the reciprocating rack 4042 drives the lighting fixture 203 to rotate within a certain angle via the reciprocating gear 2031, thus controlling the pitch angle of the lighting fixture. Simultaneously, the time-sharing block 3021 and the inclined edge of the time-sharing gear groove 4011 of the internal drive mechanism of the yaw mechanism 3 abut against each other, causing the time-sharing block 3021 to retract into the pitch drive shaft 402 to avoid the rotation of the pitch gear 401 and compress the positioning spring 3022. This ensures that the motor 204 does not change the yaw angle of the lighting fixture when rotating in the opposite direction. When used in a fixed illumination scenario, the yaw and pitch angles of the lighting fixture 203 are adjusted to the desired angles.Simply hover the drone body 1 at a suitable altitude for use. When a unidirectional yaw-rotation lighting effect is needed, simply control the regulating motor 204 to rotate continuously forward or the drone body 1 to yaw continuously. When a reciprocating pitch lighting effect is needed, simply control the regulating motor 204 to rotate continuously in reverse. When both unidirectional yaw-rotation and reciprocating pitch lighting effects are needed simultaneously, control the drone body 1 to yaw continuously and control the regulating motor 204 to rotate continuously in reverse. This allows for adaptation to different lighting needs in various scenarios.

[0035] In another embodiment, gear-like parts in the lighting assembly are preferably made of carbon fiber reinforced polyoxymethylene or high-strength PEEK materials. These engineering plastics have good self-lubricating properties, are wear-resistant and vibration-resistant, and have a density of only about 1 / 5 that of metal gears. The drive mechanism and worm gear and other force-bearing components are made of AZ31B magnesium alloy or 7075 aerospace aluminum alloy, which have a density much lower than steel and have sufficient structural strength to withstand the impact load when the motor switches between forward and reverse rotation. Shaft-like parts are made of 6063 aluminum alloy hollow shafts instead of solid steel shafts, which significantly reduces weight without affecting transmission stability. After the entire structure adopts the above-mentioned lightweight material combination, the total weight of the transmission structure can be controlled within 1 / 3 of the weight of the dual-motor drive system. In the case of drone mounting, it can minimize the overall load and further improve the endurance and flight stability.
