Technical Field

[0001] This application relates to the technical field of unmanned aerial vehicle (UAV) application equipment, and in particular to an auxiliary device for traffic enforcement UAVs. Background Technology

[0002] Drones are increasingly being used in traffic enforcement, enabling functions such as aerial patrols and capturing traffic violations.

[0003] Currently, drones used for traffic enforcement are equipped with lighting devices on their bottoms to ensure convenient nighttime use and clear video recording for evidence collection, making it easier for staff to use them.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Since the lighting device is fixed on the drone, its illumination angle follows the drone's flight direction. However, the existing drone's camera can illuminate from multiple angles, and its shooting angle does not follow the drone's direction. This makes it inconvenient for the lighting device to assist the camera device, thus affecting the camera's shooting effect. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a traffic enforcement drone auxiliary device.

[0006] This application provides a traffic enforcement drone auxiliary device, which adopts the following technical solution: Optionally, a traffic enforcement drone auxiliary device includes a mounting plate, a lighting lamp, and a rotating assembly. The mounting plate is disposed above the lighting lamp, the lighting lamp is connected to the rotating assembly, and the rotating assembly is connected to the mounting plate.

[0007] The above scheme uses a servo motor and a limiting plate to rotate the lighting lamp below the limiting plate. The rotation of gears causes the vertical plate to adjust the front and rear angles of the limiting plate and the lighting lamp. The lighting lamp is fixed by a fixing shell, and the auxiliary device is installed below the drone using a mounting plate.

[0008] Optionally, it may also include a fixing component, which includes a clamp and a bolt; The clamping ring is connected to the bolt and is positioned above the mounting plate.

[0011] The above solution utilizes the meshing of a rack and pinion to drive the gear within the fixed housing via an electric actuator, thereby adjusting the illumination angle of the lighting lamp. Optionally, it may also include an adjustment assembly, which includes a rotating plate, a mounting housing, a slider, and a slide groove; The rotating plate is connected to the mounting plate, and the rotating plate is connected to the mounting shell. The top of the mounting shell is provided with a sliding groove, which is connected to a slider, and the slider is connected to a clamping ring.

[0012] The above solution, through the cooperation of the slider and the groove, ensures that the clamping ring is installed in a position that matches the bottom of the drone, while the rotating plate can adjust the position of the clamping ring, making it convenient to install the auxiliary device on different models of drones.

[0013] Optionally, the rotating assembly further includes a slider; The slide bar is connected to the rack and pinion, and the slide bar is connected to the fixed shell.

[0014] The above solution uses a slider to limit the rack, ensuring its stability during movement and guaranteeing stable meshing between the rack and the gear.

[0016] The above solution connects the electronic components on the auxiliary device to the control center on the drone through the connector, so that the illumination direction of the lighting lamp and the camera are the same.

[0017] Optionally, the mounting plate is connected to the fixing frame, and the fixing frame is connected to the battery.

[0018] The above solution uses a fixed frame to fix the battery to the mounting plate and uses the battery to power the auxiliary device, making it stable during operation.

[0019] In summary, this application includes the following beneficial technical effects: This invention, by setting up a rotating component and a lighting lamp, and through the cooperation between the fixed shell, the servo motor and the limiting plate, enables the lighting lamp to drive the limiting plate to rotate at the bottom of the fixed shell via the servo motor.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an auxiliary device for traffic enforcement drones, such as... Figure 1 and 2As shown, mounting plate 1 serves as the supporting foundation for the lighting system and is made of carbon fiber composite material. Lighting lamp 2 is the core component for supplementary lighting in law enforcement scenarios, employing a high-brightness LED light source. The lamp housing is made of aluminum alloy and has an IP66 waterproof and dustproof rating, allowing normal operation in rain and snow. Heat dissipation fins are integrated at the rear of the lamp body to ensure continuous lighting for 2 hours without overheating protection. Lighting lamp 2 is rigidly connected to rotating assembly 3 via a flange made of stainless steel. The fixed shell 304 serves as the protective shell for the internal transmission structure and is made of ABS engineering plastic injection molding. The housing is molded into a rectangular shape, with the top fixed to the lower surface of the mounting plate 1 by countersunk bolts. Reinforcing ribs are provided on the inner wall of the housing to improve impact resistance. The fixed housing 304 is rotatably connected to a gear 308 via a bearing seat. The gear 308 is a spur gear. When the gear 308 rotates, it causes the vertical plate 303 to rotate left and right, thus changing the angle of the lighting lamp 2. Furthermore, the limiting plate 301 is fixed to the servo motor 302 via a motor bracket, allowing the servo motor 302 to directly drive the lighting lamp 2 to rotate at the bottom of the limiting plate 301, thus changing its angle. The illumination angle is wider. The connector 6, as the core component of electrical control, adopts a flame-retardant ABS engineering plastic shell. It is connected to the servo motor 302 through gold-plated terminals and uses twisted-pair shielded cable to transmit control signals and power. The cable length is customized according to the installation distance. The grounded shielding layer can effectively resist electromagnetic interference. The connection with the electric actuator 306 adopts an aviation plug structure. The plug has IP65 waterproof and dustproof performance and a plug-in life of ≥500 times, ensuring stable and reliable power transmission. The connector 6 also integrates a PWM signal generator, which can receive TTL level command signals from the UAV flight control system to achieve precise speed adjustment and stroke control of the servo motor 302 and the electric actuator 306. The battery 7 provides independent power supply for the device and is connected to the backup power interface of the connector 6 through a DC power line. A 10A fuse is connected in series in the middle of the cable. When the main power is interrupted, the power supply can be automatically switched to ensure that the lighting component and the rotating component 3 can work continuously for ≥45 minutes. The fixed frame 8 has heat dissipation holes on the side. With the battery's own heat dissipation design, the battery operating temperature can be controlled within the range of -20℃ to 60℃, ensuring power supply stability and safety.

[0025] Please see Figure 3 As the power input component of the gear 308 transmission, the rack 305 and the gear 308 adopt a full-width meshing method to ensure stable power transmission and no tooth surface slippage. By using the electric push rod 306 to push the rack 305 to move, the rack 305 meshes with the gear 308, thereby driving the angle of the lighting lamp 2 to change.

[0026] Please see Figure 4The slide bar 307, as a guide auxiliary component for the linear motion of the rack 305, is made of wear-resistant bronze and has self-lubricating properties, avoiding dust adhesion problems caused by adding additional lubricant. The slide bar 307 has an overall elongated plate-like structure, which ensures stability when the rack 305 moves, guaranteeing stable meshing between the rack 305 and the gear 308.

[0027] Please see Figure 5 The clamp 401 is milled from high-strength aluminum alloy and has a semi-circular arc structure. Its inner diameter is compatible with the diameter of the drone's mounting rod, allowing for replacement with clamps of the appropriate size for different drone models. The inner side of the clamp 401 features anti-slip textures and a 1mm thick silicone anti-slip pad to increase friction with the mounting rod and prevent rotation or slippage during flight. Both ends of the clamp 401 extend outwards to form connecting lugs, with grooves on the top of the lugs. During installation, bolts 402 are inserted into the grooves on the top of the lugs and tightened. The clamping ring 401 is fixed to the hanging rod at the bottom of the drone. The rotating plate 501 has a shaft hole in the center and is rotatably connected to the bearing seat on the upper surface of the mounting plate 1 through a stainless steel rotating shaft. A damping pad is installed at the rotating shaft, and the rotation resistance is adjustable to ensure that the rotating plate 501 can rotate 360° and be positioned at any angle to meet the mounting requirements in different directions. The mounting groove 504 and the slider 503 are both trapezoidal and can slide and engage, allowing the slider 503 to move along the direction of the groove 504, thereby adjusting the position of the clamping ring 401, so that the device can be installed on different models of drones.

[0028] The implementation principle of the traffic enforcement drone auxiliary device in this application embodiment is as follows: The device achieves a stable connection with different models of drones through the fixing component 4 and the adjusting component 5. The rotating plate 501 can rotate 360° and is locked in place by the positioning pin. With the sliding cooperation of the sliding groove 504 on the top of the mounting shell 502 and the sliding block 503, the spacing and angle of the clamping ring 401 can be flexibly adjusted. After adjustment, the clamping ring 401 is tightened by the bolt 402. The anti-slip texture on the inner side of the clamping ring 401 and the silicone pad increase the friction, forming a triple fixing structure of "rotation adjustment + sliding positioning + rigid locking". This ensures that the device does not loosen or shift when the drone flies at high speed or makes a sudden stop and turn. The installation compatibility covers mainstream law enforcement drone models. The auxiliary device is connected to the drone via the connecting seat 6. The paths are connected, allowing the servo motor 302 on the limit plate 301 to receive control signals and directly drive the lighting lamp 2 to rotate around the hinge axis. This allows for precise focusing on law enforcement targets such as vehicle cabs and accident scene details. Simultaneously, the electric push rod 306 extends and retracts, driving the rack 305 to move linearly along the slide groove of the fixed shell 304. The rack 305 meshes with the gear 308, driving the vertical plate 303 and the lighting lamp 2 to rotate vertically as a whole. The slide bar 307 is connected to the back of the rack 305 and moves stably under the limit of the slide bar 307, forming a "double guide" structure that restricts the radial swing of the rack 305, ensures precise meshing of the gear 308, and achieves 360° continuous rotation without dead angles. This meets the needs of large-scale patrol lighting, making it more convenient for staff to use.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
