Description

Technical Field

[0001] This utility model relates to the field of drone propeller protection frame technology, and in particular to a drone propeller protection frame. Background Technology

[0002] A drone is an aircraft that does not require a pilot to operate. It completes flight missions through remote control or autonomous programs. It consists of core components such as the fuselage, power system, control system, and mission payload. It generates lift by propeller or jet propulsion and can flexibly perform a variety of tasks such as aerial photography, surveying and mapping, and logistics delivery.

[0003] Existing drone propeller guards have a fixed diameter structure that cannot be adjusted. This rigid design means the guard can only fit propellers of a specific size. When users need to replace their drones with different models or upgrade to larger propellers, they must purchase entirely new guard components. This not only increases operating costs but also wastes resources.

[0004] Therefore, it is necessary to design a drone propeller protective frame to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the disadvantage of drone propeller guards being unable to adjust their size, the technical problem of this utility model is to provide a drone propeller guard.

[0006] The technical implementation scheme of this utility model is as follows: A drone propeller protective frame includes a base, a drone body, a camera, a bracket, propellers, connecting rods, fixing plates, bolts, nuts, guide rods, protective frames, turntables, limit rods, guide blocks, and an adjustment mechanism. The drone body is fixedly connected between the tops of two bases. A camera is rotatably connected to the front side of the drone body. Two brackets are fixedly connected to both sides of the upper part of the drone body. Each bracket is rotatably connected to a propeller. A connecting rod is installed at the bottom of each propeller. A fixing plate is fixedly connected to each connecting rod. Multiple bolts are fixedly connected to each fixing plate. Each bolt passes through a bracket. A nut is threaded onto the upper part of each bolt. By tightening the nut, the fixing plate and connecting rod are fixed to the bracket. Multiple guide rods are fixedly connected to the upper part of each connecting rod. A protective frame is slidably connected to each guide rod. A turntable is rotatably connected to the lower part of each connecting rod. Multiple protrusions are provided on the top surface of the turntable. Multiple limit rods corresponding to each protective frame are fixedly connected to the turntable. A guide block is rotatably connected to each protective frame.

[0007] Optionally, the adjustment mechanism includes a limit block, a sliding sleeve, a spring, and a knob. The lower part of the connecting rod is fixedly connected to the limit block, and the lower part of the connecting rod is slidably connected to the sliding sleeve. The lower part of the sliding sleeve has a slot corresponding to the protrusion. By inserting the protrusion into the slot, the turntable is fixed. A spring is connected between the limit block and the lower part of the sliding sleeve. A threaded groove is opened in the middle of the connecting rod, and a knob is threadedly connected to the middle of the connecting rod. By pressing the sliding sleeve with the knob, the sliding sleeve presses the spring, and the spring, due to tension, inserts the protrusion of the turntable into the slot of the sliding sleeve.

[0008] Optionally, it also includes support rods, with each turntable having a support rod fixedly connected to its bottom.

[0009] Optionally, it also includes a cushioning pad, with a cushioning pad fixedly connected to the bottom of each support rod.

[0010] Optionally, a protective cover is also included, with each protective frame having a protective cover fixedly attached to its top.

[0011] Optionally, the protective frame is made of carbon fiber.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets multiple guide rods on the connecting rod and slides the protective frame on the guide rods, so that the user can make lateral adjustments according to the actual length and rotation radius of different models of propeller blades. This structure breaks through the limitation of traditional fixed protective frames that can only be adapted to a single size, improves the versatility and adaptability of the equipment, and, together with the bolt and nut structure, can lock the position of the protective frame to ensure that it remains stable during flight or transportation, effectively preventing the propeller blades from being damaged by collision.

[0013] 2. This utility model adopts a design that links the turntable and the limiting rod, and achieves the angle locking function through an adjustment mechanism composed of a sliding sleeve, a spring and a knob. The top of the turntable is provided with multiple protrusions, which cooperate with the slots on the sliding sleeve to achieve multi-angle adjustment and precise positioning.

[0014] 3. In this utility model, the protective frame is made of high-strength, lightweight carbon fiber material, which reduces the overall weight while ensuring structural strength. The bottom is equipped with support rods and buffer pads to enhance the stability and shock absorption capacity between the protective frame and the ground or other contact surfaces. The protective sleeve further prevents scratch damage to the blade surface, thereby improving equipment safety and service life. Attached Figure Description

Detailed Implementation

[0020] Example: A protective frame for drone propellers, such as Figures 1-4As shown, the device includes a base 1, a drone body 2, a camera 3, a bracket 4, propellers 5, a connecting rod 6, a fixing plate 7, bolts 8, nuts 9, a guide rod 10, a protective frame 101, a turntable 11, a limit rod 12, a guide block 13, a limit block 14, a sliding sleeve 15, a spring 16, a knob 17, and a protective sleeve 20. The two bases 1 are symmetrically distributed left and right. The drone body 2 is bolted between the tops of the two bases 1. A camera 3 is rotatably connected to the lower front side of the drone body 2. The upper left and right sides of the drone body 2... Each side is bolted to two brackets 4. A blade 5 is rotatably connected to the side of each bracket 4 that is furthest from each other. A connecting rod 6 is mounted at the bottom of each blade 5. A fixing plate 7 is fixedly connected to the side of each connecting rod 6 that is closest to each other. Multiple bolts 8 arranged in a linear array are fixedly connected to each fixing plate 7. Each bolt 8 passes through a bracket 4, and a nut 9 is threaded onto the upper part of each bolt 8. Tightening the nuts 9 fixes the fixing plate 7 and the connecting rod 6 to the bracket 4. The upper parts of each connecting rod 6 are furthest from each other. Each of the connecting rods 6 has multiple guide rods 10 fixedly connected to one side, and a protective frame 101 is slidably connected to each guide rod 10. The protective frame 101 is made of carbon fiber. Each connecting rod 6 has a turntable 11 rotatably connected to its lower part. The top surface of the turntable 11 is provided with multiple protrusions. Each turntable 11 has multiple limiting rods 12 fixedly connected to each corresponding protective frame 101. Each protective frame 101 has a guide block 13 rotatably connected to the side of each other that is close to each other. A limiting block 14 is fixedly connected to the lower part of the connecting rod 6. The lower part of the connecting rod 6 slides... The rotating disk 11 is fixed by a sliding sleeve 15 with a corresponding slot at the bottom of the sliding sleeve 15. The rotating disk 11 is fixed by inserting the protrusion into the slot. A spring 16 is connected between the limiting block 14 and the lower part of the sliding sleeve 15. A threaded groove is opened in the middle of the connecting rod 6, and a knob 17 is threadedly connected to the middle of the connecting rod 6. The sliding sleeve 15 is squeezed by the knob 17, and the sliding sleeve 15 squeezes the spring 16. Due to the tension, the spring 16 inserts the protrusion of the rotating disk 11 into the slot of the sliding sleeve 15. A protective sleeve 20 is fixedly connected to the top of each protective frame 101.

[0021] When this device is needed, first pass the bolts 8 on the fixing plate 7 through the bracket 4, and then tighten the bolts 8 to fix the fixing plate 7 and the connecting rod 6 on the bracket 4. Then, install the protective frame 101 on the guide rod 10 on the connecting rod 6. The protective sleeve 20 on the top of the protective frame 101 prevents scratching the surface of the blade 5. The protective frame 101 is made of carbon fiber material, taking into account both strength and lightweight requirements. Then, adjust the transverse protective frame 101 according to the actual length and rotation radius of the blade 5 used. First, turn clockwise to loosen the knob 17, so that the connecting rod 6 moves upward. Move the knob 17 to the position where the connecting rod 6 moves upward. 7 no longer contacts the sliding sleeve 15, then rotate the turntable 11 clockwise to disengage the protrusion from the latch. At this time, the spring 16 is compressed. When rotating to the next latch, the protrusion re-inserts into the latch, the spring 16 resets, and the turntable 11 drives the limit rod 12 to rotate. When the limit rod 12 rotates, it drives the protective frame 101 to unfold outward and move on the guide rod 10. When the turntable 11 is rotated counterclockwise, the limit rod 12 rotates and drives the protective frame 101 to retract inward. Then, the counterclockwise knob 17 is rotated until the knob 17 continues to contact the sliding sleeve 15 to fix the sliding sleeve 15, thus realizing the multi-level adjustment and fixation of the angle of the protective frame 101.

[0022] like Figure 1 and Figure 4 As shown, it also includes a support rod 18 and a buffer pad 19. Each turntable 11 is fixedly connected to the bottom of a support rod 18, and each support rod 18 is fixedly connected to the bottom of a buffer pad 19.

[0023] The bottom of the turntable 11 is equipped with a support rod 18 and a buffer pad 19 to enhance the stability and shock absorption effect between the protective frame 101 and the ground or other contact surfaces.
