Description

Technical Field

[0001] This utility model relates to the field of drone accessories technology, and more specifically, it relates to a drone flight collision avoidance device. Background Technology

[0002] Due to their size, common small drones typically have their propellers mounted directly on the outside of the drone for hovering. When a drone accidentally collides with an object during flight, the propeller structure will be the first to come into contact with the object. As an important structure, the propeller is relatively fragile and easily damaged, requiring protection.

[0003] Common anti-collision devices are typically supported by mounting brackets. After the bracket is installed on the drone, the propeller is encased in a protective structure around the device, thus absorbing the impact and providing protection. However, common anti-collision devices are simple in structure and cannot be adjusted. When facing drones of different sizes, the single-structure protective device may not be able to adapt to the different propellers, resulting in misalignment and affecting the protective effect. Moreover, as anti-collision devices, they are prone to damage from frequent collisions with external objects and often need to be replaced. However, common anti-collision devices are relatively simple, with a fixed one-piece structure. When replacing them, the entire device must be replaced. Damaged anti-collision devices often have undamaged parts, which is wasteful and results in a large consumption of materials. In addition, the simple structure of common anti-collision devices only replaces the propeller in terms of impact absorption, avoiding direct impact between the propeller and external objects. They do not have the ability to buffer the impact. If the impact force is large, it will still affect the drone, and the anti-collision effect is generally limited. Utility Model Content

[0030] Please see Figure 1-5 A drone flight collision avoidance device includes a mounting frame 1, a lifting frame 2 at the outer end of the mounting frame 1, a first adjusting screw 3 rotatably connected in the lifting frame 2, a lifting frame 4 slidably connected inside the lifting frame 2, the first adjusting screw 3 cooperating with the lifting frame 4, a telescopic tube 5 at one end of the lifting frame 4, a telescopic frame 6 slidably connected to the side end of the telescopic tube 5, a mating column 7 inside the telescopic tube 5, a second adjusting screw 8 rotatably connected to the telescopic frame 6, the second adjusting screw 8 cooperating with the mating column 7, and a protective frame 9 on the telescopic frame 6.

[0031] The protective frame 9 includes an upper support 10 and a protective frame 11. The lower end of the protective frame 11 is provided with an insertion slot 12, which cooperates with the upper support 10. The protective frame 11 is provided with a first fixing bolt 13, which passes through the protective frame 11 and cooperates with the upper support 10.

[0032] In this embodiment, the mounting frame 1 provides a support structure for mounting the device to the bottom of the drone. The lifting frame 2 provides support, and the first adjusting screw 3 is rotated to engage with the lifting frame 4, driving the lifting frame 4 to move. The lifting frame 4 moves the telescopic tube 5, which in turn moves together with the telescopic frame 6 and the protective frame 9, thereby adjusting the height of the protective frame 9. Then, the second adjusting screw 8 is rotated to engage with the cooperating column 7, providing power to move the telescopic frame 6. The telescopic frame 6 slides along the telescopic tube 5, thereby moving the protective frame 9 horizontally, thus positioning the protective frame 9 to protect the drone in a suitable position.

[0033] More specifically, the upper bracket 10 and the protective frame 11 cooperate to form a protective frame 9. The upper bracket 10 provides support and adapts to the distance. The protective frame 11 surrounds the drone propeller and provides aligned protection. The upper bracket 10 enters the insertion slot 12 to cooperate with the protective frame 11. The first fixing bolt 13 passes through the protective frame 11 and is threaded to the upper bracket 10, thereby combining the upper bracket 10 and the protective frame 11 together for stable protection. By performing the above steps in different directions, the protective frame 11 can be disassembled and the protective structure replaced.

[0034] Please see Figure 1 and Figure 2As one implementation of buffer protection: a buffer spring 14 is provided at the outer end of the protective frame 11, a buffer frame 15 is provided at the outer end of the buffer spring 14, the protective frame 11 is set in the buffer frame 15, and a first buffer pad 16 is provided at the outer end of the buffer frame 15.

[0035] Specifically, a buffer frame 15 is added to the outer end of the protective frame 11 for protection via a buffer spring 14. When the drone collides with the object, the first buffer pad 16 will first come into contact with the object and absorb the impact. The first buffer pad 16 will absorb part of the impact first, and then the impact will be buffered by the buffer spring 14. The buffer frame 15 will move, and the buffer spring 14 away from the impact end will extend to dissipate the impact. Then the buffered impact will be transmitted to the drone, gradually reducing the impact effect and avoiding excessive impact on the drone.

[0036] Please see Figure 1 As a further embodiment of the buffer frame: a connecting plate 17 is provided between the buffer frames 15, and a second buffer pad 18 is provided at the outer end of the connecting plate 17.

[0037] Specifically, the connecting plate 17 surrounds the drone, providing a more comprehensive protective structure, and the second buffer pad 18 absorbs the impact of the collision, reducing the impact of the collision.

[0038] Please see Figure 1 and Figure 2 As a further embodiment of the connecting plate: the connecting plate 17 has inserts 19 at both ends and slots 20 on the buffer frame 15.

[0039] Specifically, by engaging the insert 19 with the slot 20, the insert 19 is inserted into the slot 20, and the connecting plate 17 is installed between the buffer frames 15.

[0040] Please see Figures 2-4 As a further embodiment of the telescopic frame: the telescopic frame 6 is provided with a plug-in block 21, the lower end of the upper support 10 is provided with a plug-in groove 22, and the upper support 10 is provided with a second fixing bolt 23, which cooperates with the plug-in block 21.

[0041] Specifically, the telescopic frame 6 is combined with the upper support 10 by inserting the plug 21 into the plug slot 22, and then fixed by the second fixing bolt 23.

[0042] Please see Figure 1 As a further implementation of the protective frame: a protective net 24 is provided at the upper end of the protective frame 11.

[0043] Specifically, the propeller is protected by a protective net 24 to prevent the influence of external substances.

[0044] Please see Figure 2 As a further implementation of the protective net: the protective net 24 is provided with fixing holes 25, which are engaged with the first fixing bolt 13.

[0045] Specifically, the structure provided by the fixing hole 25 cooperates with the first fixing bolt 13 to facilitate the installation of the protective net 24.

[0046] Please see Figure 1 As a further embodiment of the lifting frame: a reinforcing frame 26 is provided on the inner side of the lifting frame 2, and the reinforcing frame 26 cooperates with the mounting frame 1.

[0047] Specifically, the reinforcement frame 26 provides support, making the connection between the mounting frame 1 and the lifting frame 2 more stable.

[0048] In summary, when the entire device is in use (or running):

[0049] When using the equipment, the mounting frame 1 provides a support structure for mounting the equipment to the bottom of the drone. The reinforcing frame 26 provides a support structure, making the connection between the mounting frame 1 and the lifting frame 2 more stable. With the lifting frame 2 providing support, the first adjusting screw 3 is controlled to rotate, so that the first adjusting screw 3 cooperates with the lifting frame 4, driving the lifting frame 4 to move. The lifting frame 4 moves the telescopic tube 5, and the telescopic tube 5 cooperates with the telescopic frame 6 and the protective frame 9 to move together, thereby adjusting the height of the protective frame 9. Then, the second adjusting screw 8 is controlled to rotate, so that the second adjusting screw 8 cooperates with the cooperating column 7 to provide power, moving the telescopic frame 6. The telescopic frame 6 slides along the telescopic tube 5, thereby moving the protective frame 9 horizontally, so that the protective frame 9 protects the drone in the appropriate position.

[0050] During drone flight, the protective frame 11, supported by the upper bracket 10, surrounds the propeller to provide protection. It is connected via a buffer spring 14. A buffer frame 15 is added to the outer end of the protective frame 11 for further protection. In the event of a collision, the first buffer pad 16 will first contact the object and absorb the impact. The first buffer pad 16 absorbs a portion of the impact. The remaining impact will then be buffered by the buffer spring 14, and the buffer frame 15 will move, extending the buffer spring 14 away from the impact end to dissipate the impact. The buffered impact will then be transmitted to the drone, gradually reducing the impact effect. To prevent excessive impact from collisions that could damage the drone, the plug 19 is inserted into the slot 20 through the cooperation of the plug 19 and the slot 20. The connecting plate 17 is then installed between the buffer frames 15, and the connecting plate 17 surrounds the drone, providing a more comprehensive protective structure. The second buffer pad 18 absorbs the impact of the collision, reducing its effects. In addition, with the cooperation of the first fixing bolt 13 and the fixing hole 25, the protective net 24 is installed above the protective frame 11 to protect the propeller from external influences, providing more comprehensive protection.

[0051] When the impact device is damaged, the upper bracket 10 and the protective frame 11 cooperate to form a protective frame 9. The upper bracket 10 provides support and adapts to the distance. The protective frame 11 surrounds the drone propeller and provides aligned protection. The upper bracket 10 enters the insertion slot 12 to cooperate with the protective frame 11. The first fixing bolt 13 passes through the protective frame 11 and is threaded to the upper bracket 10, thus combining the upper bracket 10 and the protective frame 11 together for stable protection. By performing the above steps, the protective frame 11 can be disassembled and the protective structure replaced. Furthermore, by rotating the first adjusting screw 3 and the second adjusting screw 8, the lifting frame 2, the telescopic tube 5, and the telescopic frame 6 can be separated. By removing the second fixing bolt 23, the telescopic frame 6 can be separated from the upper bracket 10, and the corresponding parts can be replaced according to the actual situation.

[0052] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
