Description

Technical Field

[0001] This invention belongs to the field of cane technology, and particularly relates to an intelligent visual guidance and pressure detection cane. Background Technology

[0002] As people age, more and more people need to use canes for support to ensure stability when traveling. With the development of the times, smart canes are gradually being used to assist the elderly and people with mobility impairments. Some smart canes integrate cameras, visual recognition modules and pressure sensors, which can detect obstacles in front, road conditions and the pressure distribution of the user's hands in real time, and provide visual guidance and fall warning functions.

[0003] However, the sensors in existing smart canes are mostly fixedly installed at the front of the armrest, and their detection angle cannot be adjusted according to the user's height, usage habits, or different terrains. Taller users need a larger upward angle of the camera to capture a wider field of vision, while for shorter users, the downward angle of the camera is too large, the ground occupies too much of the field of vision, and the range of obstacle recognition is limited. Therefore, the fixed angle of the sensor makes it difficult for users of different heights to obtain the ideal visual guidance effect, reducing the smart assistance capability of the cane. Summary of the Invention

In this invention, by providing an internal plug-in mechanism, when it is necessary to disassemble or install the mounting box, a tool is used to rotate the first control rod through the first control groove, which drives the second threaded rod to rotate. The first threaded seat moves and drives the plug-in rod to exit the plug-in groove through the linkage mechanism, thereby releasing the lock on the mounting box. The mounting box can then be taken out or installed from the sliding cavity, realizing the quick disassembly and assembly and reliable fixation of the mounting box. The operation is simple and labor-saving. At the same time, the multi-point cooperation between the plug-in rod and the plug-in groove ensures the stability after fixation, avoiding the mounting box from loosening due to vibration during use. It is also convenient to quickly remove the internal components for inspection or replacement during maintenance, which significantly improves maintenance efficiency.

[0017] 3. In this invention, by providing a connecting mechanism inside, when installing the top cover, a tool is used to rotate the second control rod through the second control groove, which drives the third threaded rod to rotate. The second threaded seat moves and drives the fixing rod to extend through the multi-stage linkage mechanism, entering the fixing groove on the inner wall of the mounting box, thus firmly fixing the top cover inside the mounting box. This achieves quick disassembly and assembly of the top cover, improving maintenance convenience. At the same time, the cooperation between the multi-point fixing rod and the fixing groove ensures the stability of the top cover after it is fixed, preventing it from loosening during use and effectively protecting the internal electronic equipment.

[0021] Please see Figures 1-8 The present invention provides a technical solution: an intelligent visual guidance and pressure detection cane, including a support column 1, a handrail 2 connected to the top of the support column 1, and also including a rotating base 8, a fixing device 4, a plugging mechanism 5, and a connecting mechanism 6. The rotating seat 8 is rotatably connected to one end of the handrail 2. A probe 3 is connected to one side of the rotating seat 8. A first movable cavity 7 is opened on one side of the handrail 2. A connecting rod 9 is connected to one side of the rotating seat 8. A rotating hole is opened in the inner cavity of the first movable cavity 7.

The two ends of the first pressing block 403 are attached to one side of the clamping block 406 at the corresponding position. The inner side of the clamping block 406 is attached to the outer side of the connecting rod 9. By moving the first pressing block 403 to press the clamping block 406, the clamping block 406 moves to be attached to the outer side of the connecting rod 9, thus restricting the position of the connecting rod 9. The insertion mechanism 5 is disposed in the inner cavity of the second movable cavity 10, the inner cavity of the sliding cavity 11 is slidably connected to the mounting box 12, the inner cavity of the mounting box 12 is slidably connected to the top cover 13, and a third movable cavity 14 is opened on one side of the top cover 13. The connecting mechanism 6 is disposed inside the third movable cavity 14; The fixing device 4 also includes a first threaded rod 402, a surrounding rod 407, and a return spring 408.

The bottom of the operating lever 401 is connected to the other end of the first threaded rod 402 via a rotating shaft; Specifically, for different heights, when the angle of the probe head 3 needs to be adjusted, the operator rotates the operating lever 401 in the opposite direction. The first pressing block 403 moves backward, releasing the pressure on the clamping block 406. At this time, the clamping block 406 automatically resets under the elastic force of the return spring 408 and rotates in the opposite direction around the rod 407, releasing the connecting rod 9. The probe head 3 can then be rotated to the required angle. After adjustment, the operating lever 401 is rotated in the forward direction. The first pressing block 403 moves forward, and its inclined surface presses the clamping block 406 again, overcoming the elastic force of the return spring 408 and causing the clamping block 406 to re-clamp the connecting rod 9, thus completing the angle locking.

[0022] The insertion mechanism 5 further includes a second threaded rod 503, a first rotating rod 507, and an insertion rod 513. One end of the second threaded rod 503 is rotatably connected to the inner wall of the second movable cavity 10, and the outer side of the second threaded rod 503 is threadedly connected to the first threaded seat 504; One end of the first rotating rod 507 is connected to one side of the first threaded seat 504, and the other end of the first rotating rod 507 is rotatably connected to the second rotating rod 508. The other end of the second rotating rod 508 is rotatably connected to the third rotating rod 509, and a movable plate 512 is connected to one side of the third rotating rod 509. Multiple plug-in rods 513 are connected at one end to a corresponding position on one side of the movable plate 512. The inner cavity of the second movable cavity 10 has multiple through holes. One end of the plug-in rod 513 extends into the sliding cavity 11 through the through holes in the inner cavity of the second movable cavity 10. The mounting box 12 has multiple plug-in slots 514 on one side. The plug-in rod 513 is located outside one end of the sliding cavity 11 and is slidably connected to the corresponding plug-in slot 514. The insertion mechanism 5 also includes a first control rod 501 and a second limiting block 505: One end of the first control rod 501 is connected to the other end of the second threaded rod 503. The inner cavity of the second movable cavity 10 is provided with a rotating hole. The outer side of the first control rod 501 is rotatably connected to the rotating hole in the inner cavity of the second movable cavity 10. The other end of the first control rod 501 is provided with a first control groove 502. The second limiting block 505 is connected to one side of the first threaded seat 504, and a second limiting groove 506 is provided on one side of the inner cavity of the second movable cavity 10.

One end of the sliding rod 511 is connected to a corresponding position on the inner wall of the second movable cavity 10, and the other end of the sliding rod 511 is connected to a corresponding position on the inner wall of the second movable cavity 10. Specifically, when the mounting box 12 needs to be removed for repair or replacement of internal electronic equipment, the insertion mechanism 5, through a tool, drives the first control rod 501 to rotate from the first control slot 502, causing the second threaded rod 503 to rotate and move the first threaded seat 504. The second limiting block 505 and the second limiting slot 506 cooperate to ensure that the first threaded seat 504 can only move axially, causing the first rotating rod 507 to move, causing the second rotating rod 508 to deflect, and thus moving the third rotating rod 509. This causes the movable plate 512 to move, which in turn moves the plug rod 513 away from the corresponding plug slot 514, releasing the lock on the mounting box 12. The operator can then slide the mounting box 12 out of the sliding cavity 11, disconnect the electrical connection, and perform maintenance. During installation, the mounting box 12 is pushed into the sliding cavity 11 to the correct position, and then the first control lever 501 is rotated in the opposite direction to move the movable plate 512 forward. The plug rod 513 is then reinserted into the corresponding plug slot 514, firmly fixing the mounting box 12 in the sliding cavity 11.

[0023] The connecting mechanism 6 further includes a third threaded rod 608, a third drive rod 604, and a fixing rod 601: One end of the third threaded rod 608 is rotatably connected to the inner cavity of the third movable cavity 14, and the outer side of the third threaded rod 608 is threadedly connected to the second threaded seat 605. Multiple third drive rods 604 are connected on one side to corresponding positions around the second threaded seat 605. A second drive rod 603 is rotatably connected to one side of the third drive rod 604, and a first drive rod 602 is rotatably connected to the other end of the second drive rod 603. Multiple fixed rods 601 are connected at their tops to one side of the first drive rod 602 at the corresponding position. Multiple moving slots are provided around the inner cavity of the third movable cavity 14. One end of the fixed rod 601 extends to the outside through the moving slot provided at the corresponding position in the inner cavity of the third movable cavity 14. Fixed slots 609 are provided around the inner cavity of the mounting box 12. The outer end of the fixed rod 601 is slidably connected to the fixed slot 609 at the corresponding position. The connecting mechanism 6 further includes a sliding block 610: Multiple sliding blocks 610 are connected at one end to the bottom of the corresponding fixed rod 601. The third movable cavity 14 has multiple sliding grooves 611. The outer side of the sliding block 610 is slidably connected to the corresponding sliding groove 611. The connecting mechanism 6 also includes a second control lever 606: One end of the second control rod 606 is connected to the other end of the third threaded rod 608. A rotating hole is provided on one side of the inner cavity of the third movable cavity 14. The outer side of the second control rod 606 is rotatably connected to the rotating hole provided in the inner cavity of the third movable cavity 14. The other end of the second control lever 606 is provided with a second control groove 607, and the cross-sectional shape of the second control groove 607 is hexagonal.

[0024] Specifically, through the connecting mechanism 6, a tool drives the second control rod 606 to rotate from the second control slot 607, causing the third threaded rod 608 to rotate and move the second threaded seat 605, which in turn moves the third drive rod 604, causing the second drive rod 603 to deflect and move the first drive rod 602, which in turn moves the fixing rod 601, causing the fixing rod 601 to move into the corresponding fixing slot 609, thus installing the top cover 13 into the mounting box 12. When it is necessary to remove the top cover 13 for internal maintenance, the second control rod 606 is rotated in the opposite direction, causing the second threaded seat 605 to move in the opposite direction, which in turn causes the fixing rod 601 to exit the fixing slot 609, allowing the top cover 13 to be pulled out.

[0025] Working principle: Due to varying heights, when adjusting the angle of the probe head 3, the operator rotates the operating lever 401 in the reverse direction. The first pressing block 403 moves backward, releasing the pressure on the clamping block 406. At this time, the clamping block 406 automatically resets under the elastic force of the return spring 408 and rotates in the reverse direction around the rod 407. By releasing the connecting rod 9, the probe head 3 can be rotated to the desired angle. After adjustment, rotating the operating lever 401 in the forward direction moves the first pressing block 403 forward, and its inclined surface presses the clamping block 406 again, overcoming the elastic force of the return spring 408 and causing the clamping block 406 to clamp again. Tighten connecting rod 9 to lock the angle. When it is necessary to remove the mounting box 12 for maintenance or replacement of internal electronic equipment, the first control rod 501 is rotated from the first control slot 502 via the plug-in mechanism 5. This causes the second threaded rod 503 to rotate, moving the first threaded seat 504. The second limit block 505 and the second limit slot 506 cooperate to ensure that the first threaded seat 504 can only move axially, moving the first rotating rod 507, causing the second rotating rod 508 to deflect, and moving the third rotating rod 509, thus moving the moving plate 512. The first control lever 501 is rotated in the opposite direction to move the movable plate 512 forward, allowing the operator to slide the mounting box 12 out of the sliding cavity 11 and disconnect the electrical connection for maintenance. During installation, the mounting box 12 is pushed into the sliding cavity 11 to its designated position, and then the first control lever 501 is rotated in the opposite direction to move the movable plate 512 forward. The plug-in lever 513 is then reinserted into the corresponding plug-in slot 514, firmly fixing the mounting box 12 in the sliding cavity 11. The second control lever 512 is then moved from the second control slot 607 via the connecting mechanism 6. Rotating the control lever 606 causes the third threaded rod 608 to rotate, which in turn moves the second threaded seat 605, causing the third drive rod 604 to move. This causes the second drive rod 603 to deflect, which in turn moves the first drive rod 602, causing the fixing rod 601 to move and enter the corresponding fixing groove 609, thus installing the top cover 13 into the mounting box 12. When it is necessary to remove the top cover 13 for internal maintenance, rotating the second control lever 606 in the opposite direction causes the second threaded seat 605 to move in the opposite direction, which in turn causes the fixing rod 601 to exit the fixing groove 609, allowing the top cover 13 to be pulled out.
