Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a portable UAV panoramic visual obstacle avoidance sensing integrated machine. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as unmanned aerial vehicles, are aircraft that do not require a human pilot to be directly in the cabin to operate. Ground operators send commands in real time via radio links to remotely control their flight attitude, heading, altitude, and speed. Relying on the onboard flight control system, pre-programmed flight plans, and various sensors to perceive the environment, they can achieve automatic navigation, path planning, mission execution, and even complex decision-making. The entire process requires little or no real-time human intervention.

[0003] Traditional drone designs are often bulky and cumbersome, which not only makes it difficult to fit into everyday backpacks, requiring users to prepare special, voluminous transport bags, but also causes many problems in actual travel scenarios, failing to meet users' needs for convenient, ready-to-use functionality. Utility Model Content

[0004] The purpose of this invention is to provide a portable panoramic visual obstacle avoidance sensor integrated device for drones, which can fold and store drones for easy carrying.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A portable drone panoramic visual obstacle avoidance sensing integrated device includes a body, a camera installed at the bottom of the body, multiple sets of fixing blocks installed on the side wall of the body, an arm movably connected between each set of fixing blocks, a limiting component provided at the connection between the fixing block and the arm, and a support foot connected to the end of the arm;

[0007] The limiting assembly includes a shaft that passes through and is mounted on a fixed block. The arm is fixedly mounted on the shaft. The limiting assembly also includes a circular groove formed in the side wall of the machine body. A spring is provided in the circular groove. One end of the spring is fixedly connected to the bottom of the circular groove, and the other end of the spring is connected to a pin. The bottom end of the shaft has a first square hole and a second square hole. When the arm opens, the pin is inserted into the first square hole. When the arm closes, the pin is inserted into the second square hole.

[0008] Preferably, the upper end of the support foot is hollow, and a motor is installed inside the upper end of the support foot. The upper end of the motor is provided with a drive shaft, and the drive shaft is connected to a rotating column. The upper surface of the rotating column is provided with two fixing rods. Each fixing rod is fitted with an organic wing, and a pressure block is fitted on the fixing rod. A bolt is provided in the middle of the pressure block.

[0009] Preferably, the side wall of the machine body is provided with a U-shaped groove, the U-shaped groove is made of rubber material, and the machine arm is placed in the U-shaped groove when closed.

[0010] Preferably, the angle between the center of the first square hole and the center of the second square hole along the circumferential direction is 135°.

[0011] Preferably, the lower end of the camera is at a higher horizontal level than the lower end of the support foot, so that the camera will not touch the ground when the body is placed on a horizontal surface.

[0012] Preferably, the end of the pin is round, the pin slides in the circular groove, the pin is inserted into the first square hole or the second square hole, and the end of the pin is still in the circular groove.

[0013] The technical effects achieved by this utility model are as follows:

[0014] Pull the handle on the pin towards the body to move the pin towards the body and pull it completely out of the first square hole. At this time, the spring will deform. Then rotate the arm inward by 135°, and at the same time rotate the shaft in the same direction by 135°. At this time, release the pin, the spring will rebound, and insert the pin into the second square hole to fix the arm. Rotate the bolt until it is loosened to release the constraint on the wing. Rotate the wing around its rotation axis by 90° to the folding position. Tighten the bolt to fix the wing in the folded state. When the arm is folded and stored, the folded wing will also be folded into a compact position. By folding and storing the arm and wing, the drone can be directly put into a commuter backpack, carry-on bag, or even coat pocket without the need for a special transport case.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] A portable drone panoramic visual obstacle avoidance sensing integrated machine includes a body 1, a camera 2 installed at the bottom of the body 1, multiple sets of fixing blocks 3 installed on the side wall of the body 1, an arm 4 movably connected between each set of fixing blocks 3, a limiting component 5 provided at the connection between the fixing block 3 and the arm 4, and a support foot 6 connected to the end of the arm 4.

[0025] like Figures 1-6 As shown: The panoramic vision obstacle avoidance sensing integrated machine for UAVs is a comprehensive system integrating multiple sensors and intelligent algorithms. Its core function is to ensure the UAV's autonomous obstacle avoidance and safe flight in complex environments through 360° environmental perception and real-time decision-making. Through the power structure system integrated on the fuselage 1, it achieves stable flight and maneuverability in the air. When the UAV gains forward speed, the airflow flowing through the upper and lower surfaces of the wing 10 generates a pressure difference, thereby generating the main lift, enabling the UAV to maintain level flight efficiently.

[0026] Preferably, the limiting component 5 includes a shaft 501 that is mounted through the fixed block 3, and the arm 4 is fixedly mounted on the shaft 501. The limiting component 5 also includes a circular groove opened in the side wall of the body 1. A spring 502 is provided in the circular groove. One end of the spring 502 is fixedly connected to the bottom of the circular groove, and the other end of the spring 502 is connected to a pin 503. The bottom end of the shaft 501 is provided with a first square hole 504 and a second square hole 505. When the arm 4 opens, the pin 503 is inserted into the first square hole 504. When the arm 4 closes, the pin 503 is inserted into the second square hole 505.

[0027] like Figures 1-6 As shown: Figure 1As shown, in the deployed working state of the drone, the arm 4 is held in its fully extended open position by the movable connecting mechanism at the fixing block 3, and is reliably locked by the limiting component 5. At this time, the pin 503 is inserted into the first square hole 504 to fix the arm 4, ensuring that it will not shake in the working state and ensuring structural stability during flight. After the drone has finished working, in order to significantly improve the portability and save space, the arm 4 needs to be folded and stored from its working position. Pull the handle on the pin 503 towards the body 1 to move the pin 503 towards the body 1, completely pulling the pin 503 out of the first square hole 504. At this time, the spring 502 deforms, and then the arm 4 is rotated inward by 135°, while the shaft 501 is rotated in the same direction by 135°. At this time, the pin 503 is released, the spring 502 rebounds, and the pin 503 is inserted into the second square hole 505 to fix the arm 4. The state of the arm 4 after storage is as follows. Figure 5 As shown.

[0028] Preferably, the upper end of the support foot 6 is hollow, and a motor 7 is installed inside the upper end of the support foot 6. The upper end of the motor 7 is provided with a transmission shaft 701, and the transmission shaft 701 is connected to a rotating column 8. The upper surface of the rotating column 8 is provided with two fixing rods 9. Each fixing rod 9 is fitted with an organic wing 10, and a pressure block 11 is fitted on the fixing rod 9. A bolt 12 is provided in the middle of the pressure block 11.

[0029] like Figures 1-6 As shown: During operation, motor 7 starts and drives transmission shaft 701 to rotate. This rotational motion is transmitted to rotating column 8 through transmission shaft 701, thereby causing wing 10, which is fixed to rotating column 8, to rotate synchronously. A pressure block 11 is placed above wing 10 to press it down, and bolts 12 are used to fix the pressure block 11, thus securing wing 10 and ensuring it will not detach during operation. Figure 1 As shown, the wing 10 is deployed at a flat angle in the working state. After the work is completed, the wing 10 is folded and stored. Rotate the bolt 12 until it is loosened to release the constraint on the wing 10. Rotate the wing 10 90° around its rotation axis to the folded position. Tighten the bolt 12 to fix the wing 10 in the folded state. When the arm 4 is folded and stored, the wing 10, which is already in the folded state, is then folded into a compact position.

[0030] Preferably, the side wall of the machine body 1 is provided with a U-shaped groove 13, which is made of rubber material, and the machine arm 4 is placed in the U-shaped groove 13 when closed.

[0031] like Figures 1-6As shown: After the arm 4 and wing 10 are folded and stored, the arm 4 is placed and fitted into the U-shaped groove 13 on the body 1. The U-shaped groove 13 is designed to stably support the arm 4 and effectively prevent it from accidentally loosening or falling off during carrying or transportation. In addition, since the U-shaped groove 13 is made of flexible rubber material, its inner surface can provide good cushioning and anti-slip effect when in contact with the arm 4, avoiding friction scratches or wear that may be caused by hard materials, thus providing reliable protection for the arm 4 in the stored state.

[0032] Preferably, the angle between the center of the first square hole 504 and the center of the second square hole 505 along the circumferential direction is 135°.

[0033] Preferably, the lower end of the camera 2 is at a higher horizontal level than the lower end of the support foot 6. When the body 1 is placed on the ground, the camera 2 will not touch the ground, and the support foot 6 can protect the camera 2. The body 1 has an obstacle avoidance system based on computer vision running inside, and completes path planning in conjunction with the image data captured by the camera 2. The obstacle avoidance system and path planning are common knowledge to those skilled in the art and will not be described in detail here.

[0034] Preferably, the end of the pin 503 is round, the pin 503 slides in the round groove, the pin 503 is inserted into the first square hole 504 or the second square hole 505, and the end of the pin 503 is still in the round groove.

[0035] The working principle of this utility model is as follows: Figure 1 As shown, in the deployed working state of the drone, the arm 4 is held in its fully extended open position by the movable connecting mechanism at the fixing block 3, and is reliably locked by the limiting component 5. At this time, the pin 503 is inserted into the first square hole 504 to fix the arm 4, ensuring that it will not shake in the working state and ensuring structural stability during flight. After the drone has finished working, in order to significantly improve the portability and save space, the arm 4 needs to be folded and stored from its working position. Pull the handle on the pin 503 towards the body 1 to move the pin 503 towards the body 1, completely pulling the pin 503 out of the first square hole 504. At this time, the spring 502 deforms, and then the arm 4 is rotated inward by 135°, while the shaft 501 is rotated in the same direction by 135°. At this time, the pin 503 is released, the spring 502 rebounds, and the pin 503 is inserted into the second square hole 505 to fix the arm 4. The state of the arm 4 after storage is as follows. Figure 5 As shown.

[0036] During operation, motor 7 starts and drives transmission shaft 701 to rotate. This rotational motion is transmitted to rotating column 8 via transmission shaft 701, thereby causing wing 10, which is fixed to rotating column 8, to rotate synchronously. A pressure block 11 is placed above wing 10 to press it down, and bolts 12 are used to fix the pressure block 11, thus securing wing 10 and ensuring it will not detach during operation. Figure 1 As shown, the wing 10 is deployed at a flat angle in the working state. After the work is completed, the wing 10 is folded and stored. Rotate the bolt 12 until it is loosened to release the constraint on the wing 10. Rotate the wing 10 90° around its rotation axis to the folded position. Tighten the bolt 12 to fix the wing 10 in the folded state. When the arm 4 is folded and stored, the wing 10, which is already in the folded state, is then folded into a compact position.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
