Description

Technical Field

[0001] This application relates to the technical field of robotic guide dogs, and in particular to a robotic guide dog with protective functions. Background Technology

[0002] Mechanical guide dogs, also known as intelligent mechanical guide assistive devices, are portable intelligent devices developed based on modern sensing, artificial intelligence, navigation and control technologies. Their core purpose is to provide support for independent travel for visually impaired or low-vision individuals, replacing or supplementing the functions of traditional biological guide dogs, and helping users safely and independently avoid obstacles, plan routes, and perceive their surroundings.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following defects: In the prior art, the collision protection of existing robotic guide dogs mostly relies on the rigid material of the main shell. When encountering a frontal collision, such as contact with a corner of a wall or a railing, there is a lack of an effective buffer structure. The impact force is directly transmitted to the inside of the device or the user's hand, which can not only easily cause the internal components of the machine to loosen and reduce the service life of the machine, but may also cause secondary injuries to the user.

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model, through the provision of components such as anti-collision plate II, rotating plate, and sliding plate, transmits the impact force received by anti-collision plate II to two symmetrical rotating plates rotatably connected to it. Since the other end of the rotating plate is rotatably connected to the sliding plate, the impact force is converted into a horizontal force that pushes the sliding plate along the fixed column, causing the two sliding plates to move towards each other along the fixed column. At this time, the damping spring connected between the two sliding plates is compressed, and the elastic deformation of the damping spring absorbs the collision energy. At the same time, in conjunction with the two anti-collision plates I and the anti-collision frame, the device reduces the damage caused by the impact, provides protection for the device, and extends the service life of the device.

The connecting plate is placed against the outer wall of the fixing box, where the magnetic positioning plate at the bottom of the connecting plate and the magnetic positioning post at the top of the main body are magnetically attracted. Simultaneously, the triangular moving block inside the fixing box remains extended under the elastic force of the spring telescopic post. Because the top of the snap-fit ​​block is arc-shaped, the connecting plate can be directly pressed down, causing it to retract and snap into the slot, completing the secondary fixing of the connecting plate. Disassembly is simple; just press the pressing block to remove the handle. No tools are required, and disassembly and assembly are quick. The magnetic design also makes it more convenient for blind users. Attached Figure Description

The setting of the magnetic positioning post 32 and the magnetic positioning plate 311 can facilitate blind people to quickly position the connecting plate 31 and the fixed box 3, improving the convenience of the device.

[0020] Please see Figure 2 As shown, a sliding plate 22 is slidably connected to the outer wall of the fixed column 21. Both sliding plates 22 are restricted by the fixed column 21, so that they can only move laterally. A rotating plate 24 is rotatably connected to the front of the sliding plate 22.

[0021] Please see Figure 3 , Figure 4 As shown, a connecting block 34 is fixedly connected to the top of the connecting plate 31. A handle 341 is rotatably connected to the outer wall of the connecting block 34. A sliding groove is provided on the back of the fixed box 3. A pressing block 33 is slidably connected to the inner wall of the sliding groove. The outermost part of the pressing block 33 is larger to facilitate operation by blind people. A pulley 331 is rotatably connected to the front of the pressing block 33. The left and right sides of the fixed box 3 are provided with slots. A snap-fit ​​block 36 is slidably connected to the inner wall of the slot on the right side.

[0022] Please see Figure 2 As shown, the front of the rotating plate 24 is rotatably connected to the back of the anti-collision plate 241, and a damping spring 23 is fixedly connected to the right side of the sliding plate 22. There are two sliding plates 22.

[0023] Please see Figure 4 As shown, a connecting plate 351 is fixedly connected to the left side of the snap-fit ​​block 36. A triangular moving block 35 is fixedly connected to the back of the connecting plate 351. There are two triangular moving blocks 35, and the inclined surface of the triangular moving block 35 is in contact with the pulley 331. The back of the triangular moving block 35 is in contact with the outer wall of the pulley 331. A slot is opened on the right side of the connecting plate 31. The inner wall of the slot is engaged with the outer wall of the snap-fit ​​block 36. A spring telescopic column 352 is fixedly connected to the left side of the triangular moving block 35.

[0024] Please see Figure 2 As shown, the left side of the sliding plate 22 located on the right is fixedly connected to the right side of the damping spring 23, and there are two rotating plates 24, which are symmetrically arranged.

[0025] The implementation principle of a robotic guide dog with protective function in this application embodiment is as follows: The anti-collision plate 11 on the outer wall of the main body 1 is made of rubber. In daily use, it can directly block minor collisions from the side, such as accidental contact by a pedestrian's arm or scratches from small obstacles, preventing deformation of the shell of the main body 1. At the same time, the anti-collision frame 25 on the top of the main body 1 is a metal frame. Its bottom is fixed to the main body 1 and its top is rigidly connected to the top of the vision sensor 12, forming a protective space around the top and sides of the vision sensor 12. When foreign objects, such as fallen branches or hanging cables, approach, the anti-collision frame 25 first contacts the foreign object and absorbs the impact force, directly protecting the vision sensor 12 from impact and ensuring that it continuously collects environmental images and obstacle information, providing accurate data for the navigation module. When the robotic guide dog encounters an obstacle such as a corner or the edge of a step, the first part to come into contact with the obstacle is the second anti-collision plate 241. The impact force on the second anti-collision plate 241 is transmitted to the two symmetrical rotating plates 24 that are rotatably connected to it. Since the other end of the rotating plate 24 is rotatably connected to the sliding plate 22, the impact force is converted into a horizontal force that pushes the sliding plate 22 to slide along the fixed post 21, causing the two sliding plates 22 to move towards each other along the fixed post 21. At this time, the damping spring 23 connected between the two sliding plates 22 is compressed. The elastic deformation of the damping spring 23 absorbs the collision energy and slows down the movement speed of the sliding plate 22 through damping, avoiding rigid impact. When the impact force disappears, the damping spring 23 returns to its original deformation, pushing the sliding plate 22 to reset. This causes the rotating plate 24 and the second anti-collision plate 241 to return to their initial positions, completing the buffer reset and ensuring that the subsequent collision protection function works normally. When the handle 341 needs to be installed, the connecting plate 31 is placed against the outer wall of the fixing box 3. At this time, the magnetic positioning plate 311 at the bottom of the connecting plate 31 and the magnetic positioning post 32 at the top of the main body 1 are attracted by magnetic force, realizing the initial positioning of the connecting plate 31. At the same time, the triangular moving block 35 inside the fixing box 3 remains extended under the elastic force of the spring telescopic post 352. Since the top of the snap-fit ​​block 36 is arc-shaped, the connecting plate 31 can be pressed down directly, causing the snap-fit ​​block 36 to retract and snap into the slot, completing the secondary fixing of the connecting plate 31. When the handle 341 needs to be removed for maintenance, press it into the fixing box 3. Press the pressing block 33. The pressing block 33 slides down along the sliding groove on the back of the fixed box 3. The two pulleys 331 on its front move down synchronously and press the inclined surfaces of the two triangular moving blocks 35. After being pressed by the pulleys 331, the triangular moving blocks 35 overcome the elastic force of the spring telescopic column 352 and move into the fixed box 3. This causes the connecting plate 2 351 and the snap-fit ​​block 36 to move synchronously, so that the snap-fit ​​block 36 disengages from the snap-fit ​​groove of the connecting plate 1 31. At this time, pull the handle 341 upward to separate the magnetic positioning plate 311 at the bottom of the connecting plate 1 31 from the magnetic positioning column 32, thus completing the disassembly of the handle 341. The operation is tool-free, convenient and efficient. It can also be quickly disassembled and assembled. The magnetic design also makes it more convenient for blind people to operate.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
