Description

Technical Field

[0001] This application relates to the field of drone collision avoidance technology, specifically a drone collision avoidance device. Background Technology

[0002] With the rapid development of drone technology, drones have been widely used in various fields such as agricultural plant protection, logistics and distribution, aerial photography, geographic surveying and mapping, and environmental monitoring. However, the flight safety of drones, especially collision avoidance, remains a pressing problem that needs to be solved.

[0003] During drone flight, due to the complex flight environment and the presence of unpredictable obstacles or other aircraft, existing drone collision avoidance devices are usually directly integrated with the drone shell, or the collision avoidance components are threaded to the shell. When the drone collides with the shell or falls from a height and damages the collision avoidance components, the screws need to be unscrewed to replace the entire drone shell or the collision avoidance components, which is not convenient.

[0004] Therefore, this application provides a drone collision avoidance device to solve the above problems. Utility Model Content

[0005] This application provides a drone collision avoidance device, which aims to solve the problem mentioned in the background art that the drone has a high risk of colliding with obstacles during its flight due to the complex flight environment and the presence of unpredictable obstacles or other aircraft.

[0006] To achieve the above objectives, this application provides the following technical solution: a drone anti-collision device, comprising a drone body and a landing bracket mounted on the drone body, wherein a plurality of fixed arms are equidistantly arranged on the drone body and a propeller is mounted on the fixed arms, and a protective mechanism is provided on the fixed arms.

[0007] The protective mechanism includes a protective ring mounted on a fixed arm. Protective covers are symmetrically distributed at the upper and lower ends of the protective ring. Slots for installing the protective covers are provided at both the upper and lower ends of the protective ring. A positioning ring block for inserting into the slot is fixedly installed on the side of the protective cover near the protective ring. The protective cover is installed by snap-fit, which is convenient for disassembly and assembly. If one set of protective covers is damaged by impact, it can be replaced individually, thereby reducing maintenance costs.

[0008] Preferably, an anti-detachment silicone ring is installed on the slot of the protective ring, and the elasticity of the anti-detachment silicone ring provides compression to the positioning ring block, thereby preventing the protective cover from being dislodged by vibration or impact.

[0009] Preferably, the fixed arm has a mounting groove, and the protective ring has symmetrically installed connecting seats for insertion into the mounting groove. The mounting groove on the fixed arm is for installing the connecting seats on the protective ring to play a calibration role.

[0010] Preferably, the fixed arm has an internal cavity, in which a fixed rod is installed. The protective ring has movable rods symmetrically distributed around the fixed rod. The end of the movable rod near the mounting groove is inserted into the fixed arm and the connecting seat in sequence, using a plug-in fixing method. Compared with screw fixing, this method does not require additional openings and can make the whole unit lighter. After the connecting seat is aligned with the mounting groove and plugged in, the movable rod passes through the mounting groove, thereby connecting the protective ring and the fixed arm as one unit.

[0011] Preferably, the movable rod is symmetrically fitted with positioning seats, and each positioning seat is fixedly connected to the accommodating cavity of the fixed arm. The fixed rod is fitted with a sleeve, and the two ends of the sleeve are respectively fixedly fitted with the two movable rods. The sleeve is fitted onto the fixed rod to prevent deviation when the sleeve moves. The positioning seats are fixed in the accommodating cavity of the fixed arm and fitted onto the movable rod, so that the movable rod can move normally within the limit.

[0012] Preferably, a push plate is fixedly installed at the upper end of the sleeve, and a movable groove for sliding connection of the push plate is provided on the fixed arm. A spring is connected to the side of the sleeve away from the mounting groove. The spring is sleeved with the movable rod. The push plate is connected to the sleeve. When the protective ring is disassembled or assembled, the push plate needs to be manually pushed. The spring sleeved on the movable rod plays the role of resetting the push plate.

[0013] This anti-collision device utilizes a protective ring installed on a fixed arm. A protective cover is then attached to the ring via slots on its upper and lower parts. Both the protective ring and the protective cover are made of polycarbonate and feature a lightweight design. This design protects the propellers without compromising the drone's energy consumption due to excessive weight. The snap-fit ​​installation method facilitates easy assembly and disassembly. If one set of protective covers is damaged by an impact, it can be replaced individually, thus reducing maintenance costs.

[0014] This anti-collision device uses a plug-in fixing method, which, compared to screw fixing, does not require multiple holes, makes the whole device lightweight, and is easy to disassemble and assemble. If one of the protective covers is damaged by an impact, it can be replaced individually, thereby reducing maintenance costs. Attached Figure Description

[0023] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a drone collision avoidance device, such as Figure 1-6 As shown, the anti-collision device includes a drone body 1 and a landing support 2 mounted on the drone body 1. Several fixed arms 3 are evenly distributed on the drone body 1 and propellers 4 are mounted on the fixed arms 3. A protective mechanism 5 is provided on the fixed arms 3.

[0025] The protective mechanism 5 includes a protective ring 51 mounted on the fixed arm 3. Protective covers 52 are symmetrically distributed at the upper and lower ends of the protective ring 51. Slots 55 for mounting the protective covers 52 are provided at both the upper and lower ends of the protective ring 51. A positioning ring block 54 for inserting into the slot 55 is fixedly installed on the side of the protective cover 52 near the protective ring 51.

[0026] Specifically, a protective ring 51 is installed on the fixed arm 3, and a protective cover 52 is installed by means of the slots 55 opened at the top and bottom of the protective ring 51. The protective ring 51 and the protective cover 52 are made of polycarbonate and adopt a lightweight material design. While protecting the propeller 4, it will not affect the normal energy consumption of the drone body 1 due to excessive weight.

[0027] A silicone anti-detachment ring 56 is installed opposite the slot 55 of the protective ring 51.

[0028] More specifically, the anti-detachment silicone ring 56 installed inside the slot 55 is used to prevent the protective cover 52 from detaching when it is inserted into the positioning ring block 54. During the flight of the drone body 1, the elasticity of the anti-detachment silicone ring 56 provides pressure to the positioning ring block 54, thereby preventing the protective cover 52 from being dislodged by vibration or impact.

[0029] The fixed arm 3 has a mounting groove 31, and the protective ring 51 has symmetrically installed connecting seats 53 for inserting into the mounting groove 31.

[0030] Furthermore, the mounting groove 31 on the fixed arm 3 is used for the installation of the connecting seat 53 on the protective ring 51 for calibration. During installation, the protective ring 51 and the protective cover 52 are not connected. The protective cover 52 is installed after the protective ring 51 is installed with the fixed arm 3.

[0031] The fixed arm 3 has an internal cavity, in which a fixed rod 32 is installed. Inside the protective ring 51, movable rods 34 are symmetrically distributed around the fixed rod 32. The end of the movable rod 34 near the mounting groove 31 is inserted into the fixed arm 3 and the connecting seat 53 in sequence.

[0032] Furthermore, the cavity provided in the fixed arm 3 is mainly used to install structural parts that fix the connecting seat 53. This design stores the main fixing parts inside the fixed arm 3, preventing the parts from being exposed to the outside and thus damaged. At the same time, the plug-in fixing method, compared with screw fixing, does not require additional openings and can make the whole lighter. After the connecting seat 53 is aligned with the mounting groove 31 and plugged in, the movable rod 34 passes through the mounting groove 31, thereby connecting the protective ring 51 and the fixed arm 3 as one unit.

[0033] Positioning seats 33 are symmetrically sleeved on the movable rod 34, and the positioning seats 33 are all fixedly connected to the accommodating cavity of the fixed arm 3. A sleeve 37 is sleeved on the fixed rod 32, and the two ends of the sleeve 37 are respectively fixedly sleeved to the two movable rods 34.

[0034] It should be noted that the sleeve 37 is fitted onto the fixed rod 32 to prevent the sleeve 37 from shifting when it moves. The positioning seat 33 is fixed in the cavity of the fixed arm 3 and fitted onto the movable rod 34 so that the movable rod 34 can move normally within the limit.

[0035] A push plate 36 is fixedly installed on the upper end of the sleeve 37. A movable groove 38 for sliding connection of the push plate 36 is provided on the fixed arm 3. A spring 35 is connected to the side of the sleeve 37 away from the mounting groove 31. The spring 35 is sleeved with the movable rod 34.

[0036] It is worth mentioning that the push plate 36 is connected to the sleeve 37. When the protective ring 51 is disassembled or assembled, the push plate 36 needs to be pushed manually. The spring 35 on the movable rod 34 plays the role of resetting the push plate 36.

[0037] In use, a protective ring 51 is installed on the fixed arm 3, and a protective cover 52 is respectively installed by the slots 55 opened on the top and bottom of the protective ring 51. The protective ring 51 and the protective cover 52 are made of polycarbonate and adopt a lightweight material design. While protecting the propeller 4, it will not affect the normal power consumption of the drone body 1 due to excessive weight. The snap-fit ​​installation method makes it easy to install and remove. If one of the protective covers 52 is damaged by impact, it can be replaced individually, thereby reducing maintenance costs.

[0038] 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.
