Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV propeller protective cover and a UAV. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly used in substation inspections. Substation environments are complex and diverse in their facilities and equipment, and small multi-rotor drones can be damaged during inspection operations. The causes of damage are twofold: first, mechanical failure or catastrophic weather conditions can cause the drone to lose control and crash into equipment or obstacles; second, operators may misjudge the flight environment during normal drone operation, resulting in propeller damage and equipment loss.

[0003] Based on practical experience, there is an 80% probability that the drone propellers will be damaged when a drone collides with equipment or falls to the ground. Therefore, it is necessary to equip drones with protective covers to prevent damage to the propellers in the event of an impact or accidental contact, thereby improving the overall safety of drone operation.

[0004] Currently used multi-rotor drones come from different manufacturers and models, with variations in size and appearance. Each drone's protective cover, designed specifically for its structural characteristics, is only suitable for that particular model and cannot be universally applied to others. As drones are upgraded and replaced, the number of drone models used in substations will continue to increase, leading to a corresponding increase in the types and models of protective covers. Different drones require different protective cover operation and installation procedures, resulting in complex workflows, low efficiency, high costs, and cumbersome installation. Utility Model Content

[0005] The purpose of this invention is to provide a drone propeller protective cover to solve the problem that drone protective covers in the prior art are not universally compatible; this invention also provides a drone using the drone propeller protective cover.

[0006] To achieve the above objectives, this utility model provides a drone propeller protective cover, including a protective frame and a fixed base fixedly connected to the protective frame. The protective frame is used to cover the outside of the drone propeller in a vertical direction. The protective frame includes a frame body and a first fixed arm and a second fixed arm fixedly connected to the frame body. The first fixed arm and the second fixed arm are spaced apart in a horizontal direction, and a moving space is formed between the first fixed arm and the second fixed arm for the drone propeller arm to move along the length direction of the propeller arm.

[0007] The mounting base includes a locking clamp, a clamping member, and an adjusting member. The locking clamp is fixedly connected to the first fixed arm and the second fixed arm. The adjusting member is movably mounted on the locking clamp in the horizontal direction. The clamping member is disposed at one end of the adjusting member. During its movement stroke, the adjusting member drives the clamping member to clamp the propeller arm of the UAV in the horizontal direction.

[0008] Preferably, the locking clamp includes a first plate, a second plate, and a connecting plate. The first plate is fixedly connected to the first fixed arm, the second plate is fixedly connected to the second fixed arm, and the connecting plate is connected between the first plate and the second plate. The first plate, the second plate, and the connecting plate form a U-shape. The clamping member is disposed between the first plate and the second plate, and the adjusting member is assembled on the first plate.

[0009] Preferably, the adjusting member is threadedly assembled with the first plate, and a knob is provided at the end of the adjusting member away from the clamping member.

[0010] Preferably, the clamping member includes a pressure plate with a central hole, a screw passing through the central hole, the screw being fixedly connected to the adjusting member, and a gap between the pressure plate and the adjusting member.

[0011] Preferably, the drone propeller protective cover further includes friction pads, and the friction pads are provided on the adjacent sides of the pressure plate and the second plate.

[0014] Preferably, the frame includes a plurality of protective rods spaced apart in a fan shape and a reinforcing rod connected between each of the protective rods, wherein the end of each protective rod away from the fixed base is bent in the vertical direction.

[0015] Preferably, the protective rod and the reinforcing rod are integrally formed.

[0016] This utility model also provides a drone, including the drone propeller protective cover described in any of the above technical solutions.

[0017] Compared with the prior art, the beneficial effects of this utility model embodiment of a drone propeller protective cover and drone are as follows: The frame of the protective frame is fixedly connected to the fixed base by the locking clamps of the first fixed arm, the second fixed arm and the fixed base. The gap between the first fixed arm and the second fixed arm allows the drone propeller arm to move along the length direction of the propeller arm, adjusting the assembly position of the propeller arm to adapt to drone propeller arms of different lengths; at the same time, when the adjusting component of the fixed base moves in the horizontal direction, it can drive the clamping component to clamp the drone propeller arm in the horizontal direction and fix it to the drone.

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] A preferred embodiment of the UAV propeller protective cover of this utility model is as follows: Figures 1 to 3 As shown, the drone propeller protective cover includes a protective frame 1 and a mounting base 2. The protective frame 1 is used to cover the outside of the drone propeller in a vertical direction to protect the propeller blades. The mounting base 2 is used to fix and connect to the drone propeller arm so that the protective frame 1 can be assembled onto the drone.

[0024] The protective frame 1 includes a frame body 11, a first fixed arm 12, and a second fixed arm 13. The frame body 11 can be vertically placed over the drone's propeller to protect the blades. The first fixed arm 12 and the second fixed arm 13 are fixedly connected to the frame body 11, and the first fixed arm 12 and the second fixed arm 13 are fixedly connected to the drone's propeller arm via a fixing seat 2, thereby fixing the frame body 11 to the drone.

[0025] In this embodiment, the frame 11, the first fixed arm 12, and the second fixed arm 13 of the protective frame 1 are integrally formed. The protective frame 1 is made of a lightweight, high-strength, impact-resistant, and tough material, providing good overall safety; specifically, it is made of ABS. Multiple protective covers can be installed on the drone according to the number of propellers, with each cover corresponding to a propeller and positioned on the front and rear propellers of the drone.

[0026] The first fixed arm 12 and the second fixed arm 13 are arranged horizontally at intervals and are parallel to each other. The interval between the first fixed arm 12 and the second fixed arm 13 forms a moving space for the propeller arm of the UAV to move along the length direction of the propeller arm. The interval between the first fixed arm 12 and the second fixed arm 13 can adapt to the propeller arm size of different UAVs, and the assembly position of the propeller arm with the first fixed arm 12 and the second fixed arm 13 can be adjusted to accommodate different UAVs. In this embodiment, the interval between the first fixed arm 12 and the second fixed arm 13 allows for an adjustment range of more than 100mm for the propeller arm, and the design of the adjustment range can be expanded according to the size of different UAVs.

[0027] During assembly, the protective frame 1 moves along the length of the propeller arm toward the propeller blade, increasing the distance between each protective frame 1 and the distance between each protective cover on the drone, thus increasing the protection range and making it suitable for large-sized multi-rotor drones; conversely, if the protective frame 1 moves away from the propeller blade, the protection range of the protective cover decreases, making it suitable for small-sized multi-rotor drones, thereby making the protective cover suitable for different types of drones.

[0028] The mounting base 2 includes a locking clamp 21, a clamping member 22, and an adjusting member 23. The locking clamp 21 is fixedly connected to the first fixed arm 12 and the second fixed arm 13. The adjusting member 23 is movably mounted on the locking clamp 21 in the horizontal direction, and the direction of movement of the adjusting member 23 is perpendicular to the length direction of the first fixed arm 12 and the second fixed arm 13. The clamping member 22 is disposed at one end of the adjusting member 23. When the adjusting member 23 moves in the horizontal direction, it can drive the clamping member 22 to clamp the propeller arm of the UAV in the horizontal direction, thereby fixing the mounting base 2 to the propeller arm of the UAV.

[0029] When the mounting base 2 is fixed to the propeller arm of the UAV, the clamping part 22 is clamped and fixed to the propeller arm. The connection is convenient, quick, firm and reliable, making the protective cover easy to install and remove, facilitating daily management and maintenance, improving work efficiency and reducing costs.

[0030] The frame 11 of the drone propeller guard is fixedly connected to the locking clamp 21 of the fixed base 2 via the first fixed arm 12 and the second fixed arm 13. The gap between the first fixed arm 12 and the second fixed arm 13 allows the drone propeller arm to move along the length of the propeller arm, adjusting the assembly position of the propeller arm to accommodate drone propeller arms of different lengths. At the same time, when the adjusting component 23 of the fixed base 2 moves horizontally, it can drive the clamping component 22 to clamp the drone propeller arm horizontally and fix it to the drone. Changing the horizontal position of the adjusting component 23 can match the fixing of propeller arms with different outer diameters. With the cooperation of the movable space, it can be used for drones of different specifications and models, effectively protecting the drone propeller blades. Furthermore, the fixed base 2 is easy to install and disassemble, facilitating daily management and maintenance, making drone accessories more standardized and uniform, improving work efficiency and reducing costs.

[0031] In some embodiments, the locking clamp 21 includes a first plate 211, a second plate 212 and a connecting plate 213. The first plate 211 is fixedly connected to the first fixing arm 12, the second plate 212 is fixedly connected to the second fixing arm 13, and the connecting plate 213 is connected between the first plate 211 and the second plate 212. The first plate 211, the second plate 212 and the connecting plate 213 form a U-shape. The pressing member 22 is disposed between the first plate 211 and the second plate 212, and the adjusting member 23 is assembled on the first plate 211.

[0032] The locking clip 21 is a U-shaped structure formed by a first plate 211, a second plate 212, and a connecting plate 213. The first plate 211 and the second plate 212 are parallel to each other and spaced apart in the horizontal direction. The space between the first plate 211 and the second plate 212 can be used to avoid the propeller arms of the UAV. In this embodiment, the first plate 211 is fixedly connected to the first fixed arm 12, and the second plate 212 is fixedly connected to the second fixed arm 13 by bolts.

[0033] In some embodiments, the adjusting member 23 is threadedly assembled with the first plate 211, and a knob 24 is provided at the end of the adjusting member 23 away from the clamping member 22.

[0034] The threaded assembly provides continuous adjustment, allowing for flexible changes in the distance between the clamping element 22 and the propeller arm, adapting to different drone models. The knob 24 provides a point of force for the operator to rotate the adjusting element 23, making it convenient to use. In this embodiment, by selecting threads with different helix angles, the adjusting element 23 can be self-locked with the first plate 211, ensuring that the mounting base 2 will not loosen due to vibration during drone flight.

[0035] In some embodiments, the pressure plate has a central hole in which a screw is inserted. The screw is fixedly connected to the adjusting member 23, and there is a gap between the pressure plate and the adjusting member 23.

[0036] The screw merely passes through the pressure plate without fixing it to the plate. There is a gap between the pressure plate and the adjusting component 23. The pressure plate is suspended from the screw, ensuring that the pressure plate does not rotate when the adjusting component 23 continues to tighten after the pressure plate contacts the propeller arm, thus avoiding damage to the propeller arm. The clamping component 22 uses a circular pressure plate. When the adjusting component 23 rotates and moves the pressure plate horizontally, the coverage position of the pressure plate remains unchanged, ensuring that the clamping position between the pressure plate and the UAV propeller arm is evenly stressed, preventing damage and loosening.

[0037] In some embodiments, the drone propeller cover also includes friction pads 3, with friction pads 3 provided on the adjacent sides of the pressure plate and the second plate 212.

[0038] Friction pads 3 are provided on the sides of the pressure plate and the second plate 212 that are close to each other. When the blade arm is pressed, the friction pads 3 can increase the friction force and prevent the pressure plate from sliding or loosening. In addition, the friction pads 3 usually have the characteristics of wear resistance, anti-slip and elasticity. Their elasticity can protect the blade arm and prevent it from being crushed.

[0039] In some embodiments, the first fixed arm 12 and the second fixed arm 13 each include a connecting section 14 and a fixed section 15. The connecting section 14 is connected between the fixed section 15 and the frame 11. The fixed seat 2 is fixedly connected to the fixed section 15. The distance between the fixed section 15 of the first fixed arm 12 and the fixed section 15 of the second fixed arm 13 is L1, and the distance between the connecting section 14 of the first fixed arm 12 and the connecting section 14 of the second fixed arm 13 is L2, where L1 > L2.

[0040] The first fixed arm 12 and the second fixed arm 13 are formed with connecting sections 14 and fixed sections 15, and the distance between the connecting sections 14 is greater than the distance between the fixed sections 15. The connecting sections 14 allow the blade arm to move along the length of the blade arm to accommodate the structure at the center of the larger propeller. The fixed sections 15 can be fixedly connected to the first plate 211 and the second plate 212 of the fixed base 2, so that the adjusting member 23 drives the pressing member 22 to press and fix the propeller.

[0041] In some embodiments, the connecting segment 14 is further provided with a weight reduction hole 141, which extends through the connecting segment 14 in a horizontal direction.

[0042] While ensuring the structural strength of the connecting section 14, the weight-reducing hole 141 can reduce the weight of the connecting section 14, thereby reducing the weight of the entire protective cover. In this embodiment, the weight-reducing hole 141 is specifically a triangular hole.

[0043] In some embodiments, the frame 11 includes a plurality of protective rods 111 arranged in a fan-shaped interval and a reinforcing rod 112 connected between each protective rod 111, with the end of the protective rod 111 away from the fixed base 2 bent in the vertical direction.

[0044] The frame 11 is formed by connecting the protective rod 111 and the reinforcing rod 112. While protecting the propeller, it also reduces the weight of the frame 11. The end of the protective rod 111 away from the fixed base 2 is bent in the vertical direction, so that the protective rod 111 is completely covered on the outside of the protective rod 111, avoiding damage to the propeller due to impact during the flight of the UAV.

[0045] In some embodiments, the protective rod 111 and the reinforcing rod 112 are integrally formed.

[0046] The protective rod 111 and the reinforcing rod 112 are integrally molded and can be manufactured in one piece using injection molding, simplifying the molding process of the frame 11. In other embodiments, the protective rod 111 and the reinforcing rod 112 can also be fixedly connected by screws or other structures, which can reduce storage space after disassembly.

[0047] This utility model also provides a drone, including a protective cover. The specific structure of the protective cover is the same as that of the drone propeller protective cover described in any of the above embodiments, and will not be repeated here.

[0048] In summary, this utility model embodiment provides a drone propeller protective cover and a drone. The frame of the protective cover is fixedly connected to the fixed base by a locking clamp of a first fixed arm, a second fixed arm, and a fixed base. The gap between the first and second fixed arms allows the drone propeller arm to move along the length direction of the propeller arm, adjusting the assembly position of the propeller arm to accommodate drone propeller arms of different lengths. At the same time, when the adjusting component of the fixed base moves horizontally, it can drive the clamping component to clamp the drone propeller arm horizontally and fix it to the drone. Changing the horizontal position of the adjusting component can match the fixing of propeller arms with different outer diameters. With the cooperation of the movable space, it can be used for drones of different specifications and models, effectively protecting the drone propeller. Furthermore, the fixed base is easy to install and disassemble, facilitating daily management and maintenance, making drone accessories more standardized and uniform, improving work efficiency and reducing costs.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
