Description

Technical Field

[0001] The present application relates to the field of drones, and in particular to a drone that facilitates heat dissipation. Background Art

[0002] Drones are unmanned aircraft controlled by radio remote control and self-contained programmable devices. Drones are used for imaging, traffic control, agriculture, construction, and power inspections. Lighting drones are a special type of drone whose primary function is to provide illumination through onboard lighting. These drones are typically equipped with powerful lighting systems that can provide high-brightness illumination at night or in specific scenarios.

[0003] Chinese patent application CN209196641U discloses a matrix lighting system controlled by drone signals. The system includes a drone, a load matrix light, a data cable, and a securing strap. The load matrix light is connected to the drone's MCU and the drone's battery via the data cable. The securing strap secures the load matrix light beneath the drone's arm, and the drone's MCU communicates with the drone's ground control terminal. This utility model, based on drones, enables rapid mobile lighting, overcomes altitude constraints, and provides high-altitude lighting. It is simple to operate and boasts high brightness. The drone signal acts as a light switch, making control simple.

[0004] With respect to the above-mentioned related technologies, the load matrix lamp is prone to generate excessive heat after long-term use, causing the load matrix lamp to overheat, and there is a possibility that the load matrix lamp will be damaged due to excessive temperature. Utility Model Content

[0005] In order to avoid the situation where LED lamps are damaged due to excessive temperature, the present application provides a drone that is easy to dissipate heat.

[0006] The present application provides a UAV that facilitates heat dissipation and adopts the following technical solutions:

[0007] A drone that facilitates heat dissipation comprises a body and an arm, wherein one end of the arm is connected to the body, two groups of lighting lamps are connected within the arm, each group of lighting lamps comprising a plurality of LED lamps, the two groups of lighting lamps being spaced apart along the width direction of the arm and respectively disposed near corresponding side inner walls of the arm, and two groups of heat sinks are connected to the outer wall of the arm, each group of heat sinks comprising a plurality of heat fins, the two groups of heat sinks being respectively connected to the outer walls at both ends of the arm along the width direction of the arm.

[0008] By adopting the above technical solution, when in use, the heat generated by the LED lamp is conducted to the heat dissipation fins through the side wall of the arm, and dissipated through the heat dissipation fins, thereby facilitating the heat dissipation of the LED lamp, thereby reducing the situation where the LED lamp temperature is too high and reducing the probability of damage to the LED lamp. The two groups of lighting lamps are respectively arranged close to the two groups of heat sinks, which further facilitates heat conduction and improves heat dissipation efficiency.

[0009] Optionally, a connection port is provided at the bottom of the arm, the length direction of the connection port is consistent with the length direction of the arm, a lampshade is detachably connected to the bottom of the arm, the length direction of the lampshade is consistent with the length direction of the arm, and the lampshade is covered on the connection port.

[0010] By adopting the above technical solution, the lampshade can be detachably connected to the machine arm, thereby facilitating the maintenance of the LED lamp.

[0011] Optionally, the heat dissipation fins are distributed in sequence along the length direction of the arm, and the heat dissipation fins are arranged vertically.

[0012] By adopting the above technical solution, the heat dissipation fins are arranged vertically, and two adjacent heat dissipation fins are arranged at intervals, thereby reducing the wind resistance encountered by the drone during lifting and lowering.

[0013] Optionally, the lampshade is connected to a supporting foot, and the top of the supporting foot is connected to the bottom of the end of the lampshade away from the body.

[0014] By adopting the above technical solution and adding support feet, the drone body is kept away from the ground when parked, thereby minimizing the possibility that the drone body collides with the ground and causes damage to the body when parked.

[0015] Optionally, a mounting plate is connected inside the machine arm, and the length direction of the mounting plate is consistent with the length direction of the machine arm. The mounting plate is connected to a circuit board, and the LED lamp is connected to the machine arm through the mounting plate. A number of connecting holes are provided at the bottom of the mounting plate, and a mounting block is connected to the top of the LED lamp, and the mounting block is connected to a metal sheet. The LED lamp is electrically connected to the circuit board through the metal sheet, and the connecting holes correspond one-to-one with the mounting blocks. The mounting block and the metal sheet are embedded in the connecting holes, and the mounting block is slidably connected to the connecting hole in the vertical direction. The mounting block is connected to a locking assembly, and the locking assembly is used to lock the mounting block in the connecting hole.

[0016] By adopting the above technical solution, when the LED lamp is damaged and needs to be replaced, the mounting block is unlocked from the connecting hole through the locking component, thereby facilitating the removal of the mounting block from the connecting hole. The metal sheet is then removed from the connecting hole along with the mounting block, so that the mounting block is away from the mounting plate and the metal sheet is away from the circuit board, thereby facilitating the replacement of the LED lamp.

[0017] Optionally, the mounting block is provided with a mounting groove along one side of the length direction of the mounting plate, and the length direction of the mounting groove is consistent with the length direction of the mounting plate. The locking assembly includes a locking block and a spring, and the length direction of the spring is consistent with the length direction of the mounting plate. One end of the spring is connected to the inner wall of the mounting groove along its length direction, and the other end of the spring is connected to the locking block. The locking block is slidably connected to the mounting groove along the length direction of the mounting plate, and the connecting hole is provided with a locking groove for the locking block to be embedded along the inner wall of one side of the length direction of the mounting plate.

[0018] By adopting the above technical solution, when installing the LED lamp, the mounting block is embedded in the connecting hole upward in the vertical direction. Due to the squeezing of the inner wall of the connecting hole, the locking block is embedded in the mounting groove, and the spring is deformed due to the squeezing. When the locking block approaches the locking groove, the spring restores its shape and pushes the locking block to embed into the locking groove, thereby making the mounting block stably connected to the mounting plate, and making the LED lamp stably connected to the mounting plate.

[0019] Optionally, a clearance opening is formed in the connection hole along the width direction of the mounting plate and on a side away from the other connection hole.

[0020] By adopting the above technical solution, a clearance opening is additionally provided, thereby facilitating an operator to buckle the LED lamp out of the connection hole when disassembling the LED lamp.

[0021] Optionally, an anti-slip layer is connected to the bottom of the support foot.

[0022] By adopting the above technical solution, an anti-skid layer is added to improve the stability of the drone when it is parked.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, the heat generated by the LED lamp is transferred to the heat dissipation fins through the side wall of the machine arm, and then dissipated through the heat dissipation fins, thereby facilitating the heat dissipation of the LED lamp, thereby reducing the situation of the LED lamp overheating and the probability of damage to the LED lamp. The two sets of lighting groups are respectively arranged close to the two sets of heat sinks, which further facilitates heat conduction and improves heat dissipation efficiency.

[0025] 2. When the LED lamp is damaged and needs to be replaced, unlock the mounting block from the connection hole using the locking assembly to facilitate the removal of the mounting block from the connection hole. The metal sheet is then removed from the connection hole along with the mounting block, keeping the mounting block away from the mounting plate and the metal sheet away from the circuit board, making it easier to replace the LED lamp.

[0026] 3. The heat dissipation fins are set vertically, and there is a gap between two adjacent heat dissipation fins to reduce the wind resistance when the drone is taking off and landing. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Reference Figure 2 and Figure 4 The LED lamp 530 is detachably connected to the bottom of the mounting plate 600. A mounting block 510 is connected to the top of the LED lamp 530. A metal sheet 511 is connected to the side of the mounting block 510 facing away from the LED lamp 530. The metal sheet 511 is electrically connected to the LED lamp 530. The bottom of the mounting plate 600 has several connection holes 610 for the mounting blocks 510 to fit into. The depth of the connection holes 610 is aligned with the vertical direction.
