Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an emergency lighting mounting and stabilizing bracket device for UAVs. Background Technology

[0002] With the rapid development of drone technology, its application in special scenarios such as emergency rescue, nighttime operations, and engineering inspections is becoming increasingly widespread. Among these applications, drones equipped with emergency lighting equipment have become a key means of improving operational efficiency and safety. By carrying searchlights, floodlights, and other equipment, drones can quickly achieve large-scale, highly mobile lighting coverage, effectively solving the pain points of traditional ground lighting equipment, such as inconvenience in movement and limited lighting range. This plays an irreplaceable role in scenarios such as rubble search at earthquake rescue sites, equipment debugging during nighttime power repairs, and nighttime mining in open-pit mines.

[0003] During drone flight, factors such as the high-speed rotation of the propeller and the imbalance of the equipment's own gravity inevitably generate continuous vibrations and instantaneous impacts. In existing mounting brackets, the rigid connection structure cannot buffer such vibrations, causing the lighting equipment to vibrate synchronously with the drone. The lighting equipment is prone to irregular shaking or tilting, resulting in flickering with alternating light and dark in the illuminated area, significantly reducing lighting stability and seriously affecting the accuracy of rescue personnel's observation of the target area or the operational accuracy of the personnel.

[0004] Therefore, this application provides a drone emergency lighting mounting and stabilizing bracket device to solve the above problems. Utility Model Content

[0005] This application provides a drone emergency lighting mounting and stabilizing bracket device, which aims to solve the problems mentioned in the background art, such as the imperfect design of existing mounting brackets in terms of shock absorption and anti-shake, which cannot effectively buffer the vibration and impact generated during drone flight, resulting in the lighting equipment being prone to shaking and tilting, thus affecting the lighting effect.

[0006] To achieve the above objectives, this application provides the following technical solution: an emergency lighting mounting and stabilizing bracket device for unmanned aerial vehicles (UAVs), comprising a connecting base and a lighting device for emergency lighting; a shock-absorbing and stabilizing mechanism is provided between the lighting device and the connecting base, the shock-absorbing and stabilizing mechanism comprising a U-shaped base symmetrically fixedly connected to both sides of the bottom end of the connecting base, a U-shaped frame slidably sleeved on the U-shaped base and connected to the lighting device, and a hydraulic damper fixedly installed inside the U-shaped base, the output end of the hydraulic damper being fixedly connected to the top wall inside the U-shaped frame, and a buffer spring being fitted on the hydraulic damper, the buffer spring being located between the U-shaped base and the U-shaped frame. When the lighting equipment is subjected to a downward pulling force, it will cause the U-shaped frame to slide down along the U-shaped base. During this process, the U-shaped frame will compress the buffer spring and the hydraulic damper. The buffer spring will undergo elastic deformation to absorb part of the vibration energy, while the hydraulic damper will use its damping characteristics to consume the vibration energy. The two work together to buffer vibration and impact. When the external force disappears, the elastic force of the buffer spring will push the U-shaped frame to return to its original position, and the hydraulic damper will suppress the oscillation during the return process, so that the lighting equipment can quickly return to a stable state.

[0007] Preferably, to ensure the U-shaped frame maintains vertical movement, grooves are provided on both sides of the U-shaped base to fit the side walls of the U-shaped frame. The side walls of the U-shaped frame are slidably inserted into the grooves on both sides of the U-shaped base. The grooves fitting the side walls of the U-shaped frame guide the movement of the U-shaped frame, ensuring it remains vertical and preventing deviation or tilting during movement. This ensures the normal operation of the shock-absorbing and stabilizing mechanism and further improves the stability of the lighting equipment.

[0008] Preferably, to facilitate the connection between the U-shaped frame and the lighting equipment: a connecting plate is fixedly connected to the open end of the U-shaped frame, and the connecting plate is fixedly connected to the lighting equipment by bolts. The connecting plate provides a convenient interface for connecting the U-shaped frame and the lighting equipment. The bolt connection not only ensures a firm and reliable connection but also facilitates the installation, disassembly, and maintenance of the lighting equipment. When the lighting equipment malfunctions or needs to be replaced, it can be operated quickly, improving work efficiency.

[0009] Preferably, to facilitate adjustment of the spring potential energy of the buffer spring: the bottom of the hydraulic damper is provided with an external thread, and a first nut adapted to the external thread is fitted on the hydraulic damper. The two ends of the buffer spring respectively abut against the upper end of the first nut and the top wall inside the U-shaped frame. Through the engagement of the first nut with the external thread of the hydraulic damper, the compression of the buffer spring can be easily adjusted, thereby adjusting the spring potential energy. The buffering effect can be flexibly adjusted according to different flight environments, the weight of lighting equipment, and other factors, ensuring that the shock absorption and stabilization mechanism can perform its optimal shock absorption function under various conditions.

[0010] Preferably, to facilitate the rotation of the first nut: multiple protruding rods are fixedly connected to the outer wall of the first nut, and the multiple protruding rods are arranged in a ring at equal intervals on the first nut. The protruding rods increase the friction and force points on the outer wall of the first nut, making it easier and more convenient for the operator to drive the first nut to rotate without the need for additional tools, simplifying the adjustment operation of the buffer spring's elastic potential energy and improving the adjustment efficiency.

[0011] Preferably, to prevent the upper end of the U-shaped frame from colliding with the lower end of the connecting seat: an elastic pad for contacting the U-shaped frame is fixedly connected to the lower end of the connecting seat at the position corresponding to the upper part of the U-shaped frame. The elastic pad is elastic and can contact the U-shaped frame when it moves upward, preventing a direct hard impact between the upper end of the U-shaped frame and the lower end of the connecting seat, reducing noise and vibration caused by the impact, and protecting both the U-shaped frame and the connecting seat, thus extending their service life.

[0012] Preferably, to facilitate connection with the drone's cantilever, a connecting mechanism symmetrically arranged on the connecting base for connecting to the drone's cantilever is further included. The connecting mechanism includes a first retaining ring fixedly connected to the upper end of the connecting base and a second retaining ring hinged to the first retaining ring. A screw is hinged to the end of the first retaining ring away from its hinge, and a U-shaped retaining seat adapted to the screw is fixedly connected to the end of the second retaining ring away from its hinge. A second nut, threaded onto the screw, drives the U-shaped retaining seat to move closer to the first retaining ring. This connecting mechanism allows for convenient and quick connection between the connecting base and the drone's cantilever, providing a strong and stable connection while facilitating installation and disassembly, thus improving the versatility and practicality of the support device.

[0013] Preferably, to reduce wear on the drone cantilever caused by the first and second retaining rings: silicone pads are fixedly connected to the inner walls of both the first and second retaining rings. The silicone pads are soft and elastic, reducing direct friction between the first and second retaining rings and the drone cantilever, thus reducing wear on the drone cantilever surface. Simultaneously, the silicone pads increase the friction between the retaining rings and the cantilever, making the connection more secure and preventing the support from slipping during flight.

[0014] This application utilizes the elasticity of a buffer spring and the damping effect of a hydraulic damper to effectively buffer various vibrations and impacts generated during UAV flight, significantly reducing the swaying and tilting of the lighting equipment, ensuring the stability of the lighting equipment in complex flight environments, thereby improving the lighting effect and ensuring the flight safety of the UAV.

[0015] This application allows for convenient adjustment of the compression of the buffer spring through the engagement of the first nut with the external thread of the hydraulic damper, thereby adjusting the elastic potential energy of the buffer spring. The buffering effect can be flexibly adjusted according to different flight environments, the weight of lighting equipment, and other factors, ensuring that the shock absorption and stabilization mechanism can play the best shock absorption role under various conditions.

[0016] The connection mechanism of this application can easily and quickly connect the connecting seat to the cantilever of the UAV, with a firm and stable connection, while being easy to install and disassemble, thus improving the versatility and practicality of the support device.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 This embodiment provides a drone emergency lighting mounting and stabilization bracket device, such as... Figure 1-4As shown, the support device includes a connecting base 1 and a lighting device 2 for emergency lighting. A shock-absorbing and stabilizing mechanism 3 is provided between the lighting device 2 and the connecting base 1. The shock-absorbing and stabilizing mechanism 3 includes a U-shaped base 31 symmetrically fixedly connected to both sides of the bottom end of the connecting base 1, a U-shaped frame 32 slidably sleeved on the U-shaped base 31 and connected to the lighting device 2, and a hydraulic damper 33 fixedly installed inside the U-shaped base 31. The output end of the hydraulic damper 33 is fixedly connected to the top wall inside the U-shaped frame 32. A buffer spring 34 is fitted on the hydraulic damper 33, and the buffer spring 34 is located between the U-shaped base 31 and the U-shaped frame 32. Through the elastic action of the buffer spring 34 and the damping action of the hydraulic damper 33, various vibrations and impacts generated during the flight of the UAV can be effectively buffered, significantly reducing the swaying and tilting of the lighting device 2, ensuring the stability of the lighting device 2 in complex flight environments, thereby improving the lighting effect and ensuring the flight safety of the UAV. When the lighting equipment 2 is subjected to a downward pulling force, it will cause the U-shaped frame 32 to slide down along the U-shaped seat 31. During this process, the U-shaped frame 32 will squeeze the buffer spring 34 and the hydraulic damper 33. The buffer spring 34 will undergo elastic deformation to absorb part of the vibration energy, while the hydraulic damper 33 will use its damping characteristics to consume the vibration energy. The two work together to buffer vibration and impact. When the external force disappears, the elastic force of the buffer spring 34 will push the U-shaped frame 32 to reset, and the hydraulic damper 33 will suppress the oscillation during the reset process, so that the lighting equipment 2 can quickly return to a stable state.

[0021] To ensure the U-shaped frame 32 maintains vertical movement, grooves 311 are provided on both sides of the U-shaped base 31 to fit the side walls of the U-shaped frame 32. The side walls of the U-shaped frame 32 are slidably inserted into the grooves 311 on both sides of the U-shaped base 31. The grooves 311, fitting the side walls of the U-shaped frame 32, guide the movement of the U-shaped frame 32, ensuring that the U-shaped frame 32 always maintains vertical movement and preventing it from shifting or tilting during movement. This ensures the normal operation of the shock-absorbing and stabilizing mechanism 3 and further improves the stability of the lighting equipment 2. The side walls of the U-shaped frame 32 are slidably inserted into the grooves 311 on both sides of the U-shaped base 31. The grooves 311 restrict the horizontal displacement of the U-shaped frame 32, allowing it to move vertically only along the extension direction of the grooves 311, i.e., vertically.

[0022] To facilitate the connection between the U-shaped frame 32 and the lighting equipment 2, a connecting plate 321 is fixedly connected to the open end of the U-shaped frame 32. The connecting plate 321 is fixedly connected to the lighting equipment 2 by bolts. The connecting plate 321 provides a convenient interface for connecting the U-shaped frame 32 and the lighting equipment 2. The bolt connection not only ensures a firm and reliable connection but also facilitates the installation, disassembly, and maintenance of the lighting equipment 2. When the lighting equipment 2 malfunctions or needs to be replaced, it can be operated quickly, improving work efficiency. With the connecting plate 321 fixedly connected to the open end of the U-shaped frame 32, the lighting equipment 2 is placed on the connecting plate 321, and bolts are passed through the corresponding screw holes on the connecting plate 321 and the lighting equipment 2 and tightened, thus fixing the lighting equipment 2 and the U-shaped frame 32 together.

[0023] To facilitate adjustment of the elastic potential energy of the buffer spring 34, the bottom of the hydraulic damper 33 is provided with an external thread. A first nut 35, adapted to the external thread, is fitted onto the hydraulic damper 33. The two ends of the buffer spring 34 abut against the upper end of the first nut 35 and the top wall inside the U-shaped frame 32, respectively. Through the engagement of the first nut 35 with the external thread of the hydraulic damper 33, the compression of the buffer spring 34 can be easily adjusted, thereby adjusting its elastic potential energy. The buffering effect can be flexibly adjusted according to different flight environments, the weight of the lighting equipment 2, and other factors, ensuring that the shock absorption and stabilization mechanism 3 can perform optimal shock absorption under various conditions. When the first nut 35 is rotated, because it is adapted to the external thread of the hydraulic damper 33, the first nut 35 moves up and down along the hydraulic damper 33, changing the compression degree of the buffer spring 34 and thus adjusting its elastic potential energy.

[0024] To facilitate the rotation of the first nut 35, multiple protruding rods 351 are fixedly connected to the outer wall of the first nut 35. These protruding rods 351 are arranged in a ring at equal intervals on the first nut 35. The protruding rods 351 increase the friction and force points on the outer wall of the first nut 35, allowing the operator to drive the first nut 35 to rotate more easily and conveniently without the need for additional tools. This simplifies the adjustment of the elastic potential energy of the buffer spring 34 and improves adjustment efficiency. With the multiple protruding rods 351 arranged in a ring at equal intervals on the outer wall of the first nut 35, the operator can hold the protruding rods 351 and rotate them to drive the first nut 35 to rotate together, thereby achieving the up-and-down movement of the first nut 35 on the hydraulic damper 33.

[0025] To prevent the upper end of the U-shaped frame 32 from colliding with the lower end of the connecting seat 1, an elastic pad 36 is fixedly connected to the lower end of the connecting seat 1 at the position corresponding to the upper part of the U-shaped frame 32. The elastic pad 36 is elastic and, when the U-shaped frame 32 moves upward, it can abut against the U-shaped frame 32, preventing a direct hard impact between the upper end of the U-shaped frame 32 and the lower end of the connecting seat 1. This reduces noise and vibration caused by the impact, while protecting both the U-shaped frame 32 and the connecting seat 1, extending their service life. The elastic pad 36 (made of silicone or rubber) is fixedly connected to the lower end of the connecting seat 1 at the position corresponding to the upper part of the U-shaped frame 32. When the U-shaped frame 32 moves upward to a certain position, the upper end of the U-shaped frame 32 will contact the elastic pad 36, causing the elastic pad 36 to deform and absorb the impact energy, thus providing cushioning and protection.

[0026] To facilitate connection with the drone's cantilever, a connecting mechanism 4 is also included, symmetrically arranged on the connecting base 1 for connecting to the drone's cantilever. The connecting mechanism 4 includes a first retaining ring 41 fixedly connected to the upper end of the connecting base 1 and a second retaining ring 42 hinged to the first retaining ring 41. A screw 43 is hinged to the end of the first retaining ring 41 away from its hinge, and a U-shaped retaining seat 44 adapted to the screw 43 is fixedly connected to the end of the second retaining ring 42 away from its hinge. A second nut 45 is threaded onto the screw 43 to drive the U-shaped retaining seat 44 to move closer to the first retaining ring 41. The connecting mechanism 4 allows for convenient and quick connection between the connecting base 1 and the drone's cantilever, providing a strong and stable connection while facilitating installation and disassembly, thus improving the versatility and practicality of the support device. During installation, loosen the second nut 45, remove the screw 43 from the U-shaped bracket 44, open the second retaining ring 42, attach the first retaining ring 41 to the bottom of the drone's boom, close the second retaining ring 42, rotate the screw 43 to engage it in the U-shaped bracket 44, and finally tighten the second nut 45. Under the action of the second nut 45, the U-shaped bracket 44 is pulled closer to the first retaining ring 41, thereby clamping and fixing the drone's boom between the first retaining ring 41 and the second retaining ring 42.

[0027] To reduce wear on the drone cantilever caused by the first retaining ring 41 and the second retaining ring 42, silicone pads 46 are fixedly connected to the inner walls of both the first retaining ring 41 and the second retaining ring 42. The silicone pads 46 are soft and elastic, reducing direct friction between the first and second retaining rings 41 and the drone cantilever, thus reducing wear on the drone cantilever surface. Simultaneously, the silicone pads 46 increase the friction between the retaining rings and the cantilever, making the connection more secure and preventing the support from slipping during flight. The silicone pads 46 are fixedly connected to the inner walls of the first and second retaining rings 41 and 42. When the first and second retaining rings 41 and 42 clamp the drone cantilever, the silicone pads 46 are positioned between the retaining rings and the cantilever, directly contacting the cantilever surface. Through their elastic deformation, they conform to the cantilever surface, reducing friction and wear.

[0028] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0029] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
