Description

Technical Field

[0001] This utility model relates to the field of cane technology, and in particular to an intelligent cane with high-efficiency obstacle avoidance. Background Technology

[0002] A cane is a simple device to assist walking. Due to its excellent performance and important function of facilitating walking, it is widely used among the elderly.

[0003] With the development of technology, canes have various functions to help the elderly, which can improve the convenience of the elderly in the process of walking. However, some of these functions have some shortcomings. For the elderly who are not flexible enough or have poor eyesight, they are prone to tripping over obstacles while walking, which can lead to accidents and even life-threatening situations.

[0004] Therefore, the ability of canes to detect obstacles needs to be improved, so that canes can quickly identify obstacles and promptly remind the elderly, which will help the elderly to find and avoid obstacles in time. Summary of the Invention

[0005] Therefore, this utility model was developed in view of the above problems. The purpose of this utility model is to solve the problem of unclear obstacle warnings by utilizing the design of a split airbag. This utility model achieves the above objective through the following technical solution.

[0006] A smart cane with high-efficiency obstacle avoidance includes a handle, a support device, a detection device, an obstacle avoidance device, and a stabilizing device. The support device comprises a support rod, a limiting plate, and a positioning plate. The support rod is located below the handle, with multiple receiving grooves on its outer wall and a second receiving groove in its center. The limiting plate is fixedly connected to the obstacle avoidance device at its upper end inside the support rod. A gear is located inside the positioning plate, and a rotating block is located on the side of the gear; the two mesh, and the rotation of the rotating block drives the gear to rotate, simultaneously driving the stabilizing device to move. The detection device includes a motor. The motor is located inside the support rod, with a drive rod at its upper end, and a gear is nested within the drive rod. A second drive rod is located within the drive rod. Above rod one, drive rod two is nested with shaft gear two; the obstacle avoidance device includes: a limiting rod, a compressed airbag, a small airbag, a moving plate, and a rubber block; the limiting rod includes: a rotating receiving groove, a protruding rod, and a transmission gear; the lower end of the limiting rod is set on the limiting plate; the upper side wall of the limiting rod is provided with a rotating receiving groove, and the rotating receiving groove is symmetrically provided with protruding rods, namely protruding rod one and protruding rod two, which are linked with the transmission gear; there are two compressed airbags, symmetrically arranged on the outside of the limiting rod, and a moving plate is provided at the upper end, the outer wall of which is attached to the inner wall of the support rod, and a connecting groove is provided on the inner side of which a small airbag is arranged, and the compressed airbag and the small airbag are connected; the lower end of the rubber block is connected to the moving plate, and the upper end is set in the limiting groove.

[0007] The beneficial effects of this utility model are as follows: 1. This utility model utilizes the rotational cooperation of drive rod one and drive rod two. By using different rotation methods, the protruding rods on different sides can rotate, which is beneficial to the next step of the work and ensures the accuracy of the obstacle avoidance device.

[0008] 2. This utility model utilizes an airbag to make one side of the rubber block vibrate, so that the elderly can feel the vibration of the rubber block when they hold the handle, and thus know that there is an obstacle on one side. At the same time, the speed of the rotating rod varies depending on the distance of the obstacle, which means that the frequency of the rubber block vibration varies. This allows the elderly to know the location of the road obstacle ahead based on the frequency and direction of the vibration, ensuring that the elderly can avoid the obstacle in time.

[0009] 3. The distance between the balance seat and the base of this utility model can be adjusted, which allows the stabilizing device to provide a larger support angle. At the same time, the cooperation of the hydraulic rod and the telescopic rod makes the bottom of the cane more stable, while providing greater assistance to the elderly and improving their stability when going up and down stairs.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0023] like Figure 1 As shown, a smart cane with high-efficiency obstacle avoidance includes: a handle 1, a support device 2, a detection device 3, an obstacle avoidance device 4, and a stabilizing device 5.

[0024] The handle 1 includes: an LED light 11, a limiting groove 12, and a touch sensor 13.

[0025] The handle 1 is a crank in shape, with an LED light 11 on the left side for illumination in low-light conditions to ensure the safety of the elderly while walking. A limit groove 12 is provided in the middle to accommodate the top of the obstacle avoidance device 4, so that the elderly can promptly feel the instructions issued by the obstacle avoidance device 4.

[0026] The touch sensor 13 is located in the middle of the handle 1. It is a capacitive sensor. When a person places their finger on the touch sensor 13, it can activate the warning mode and cooperate with the detection device 3 to detect falls.

[0027] like Figure 2-3 As shown, the support device 2 includes: a support rod 21, a limiting plate 22, and a positioning plate 23.

[0028] The support rod 21 is located below the handle 1, and its outer wall surface is provided with multiple receiving grooves 211, with a second receiving groove 212 in the middle, which provides support for the detection device 3.

[0029] The limiting plate 22 is located inside the upper end of the support rod 21 and is used to support the obstacle avoidance device 4 to ensure the stable operation of the obstacle avoidance device 4.

[0030] The positioning plate 23 is located inside the support rod 21, below the limiting plate 22. It is hollow inside and has a gear 231. The stabilizing device 5 is connected below it. A rotating block 232 is provided on the side of the gear 231. The two mesh with each other. The rotating block 232 rotates, driving the gear 231 to rotate. At the same time, the gear 231 drives the stabilizing device 5 to move.

[0031] like Figure 4-6 As shown, the detection device 3 includes: an ultrasonic sensor module 31, a camera module 32, a controller 33, a Beidou positioning module 34, a voice module 35, and a motor 36.

[0032] The ultrasonic sensor module 31 includes: a central ultrasonic sensor 311, a right ultrasonic sensor 312, and a left ultrasonic sensor 313; used for three-dimensional detection.

[0033] The ultrasonic sensor module 31 is installed in the receiving slot 211 and is used to detect obstacles in the road section in front of the support rod 21. The detected data is transmitted to the controller 33, which makes a judgment. When an obstacle is detected, the controller 33 receives data from two sets of ultrasonic sensor modules 31 at different heights. Each set of data contains sensor data from three different angles. By comparing the horizontal and vertical data of each set, the controller 33 judges the direction and distance of the obstacle and issues commands to the voice module 35 and the obstacle avoidance device 4. The voice module 35 provides obstacle warnings, and the obstacle avoidance device 4 provides directional warnings, so that the elderly can avoid the obstacle on their own.

[0034] The camera module 32 is installed in the receiving slot 212. It captures the image in front of the cane and transmits the image. When the cane is hit or an accident occurs, the controller 33 receives the signal when the finger is placed on the touch sensor 13 and activates the warning mode. At this time, the camera module 32 starts to capture the image and transmits the image to the controller 33. The controller 33 performs joint positioning by judging the image and the Beidou positioning module 34, and sends the current location and surrounding environment to the guardian's mobile phone. This allows the guardian to understand the current situation of the emergency encountered by the elderly and make a human judgment on whether to call the alarm, so as to avoid invalid alarms and the occupation of valuable public service resources.

[0035] The motor 36 is installed inside the support rod 21, and a drive rod 361 is installed at its upper end. The drive rod 361 is nested with a gear 3611 for meshing with the obstacle avoidance device 4. The drive rod 362 is installed above the drive rod 361, and the drive rod 362 is nested with a gear 3621.

[0036] A one-way bearing is provided between the drive rod 361 and the drive rod 362. When the drive rod 361 rotates clockwise, the drive rod 362 remains stationary. When the drive rod 361 rotates counterclockwise, it drives the drive rod 362 to rotate.

[0037] like Figure 5-9 As shown, the obstacle avoidance device 4 includes: a limiting rod 41, a compressed airbag 42, a small airbag 43, a moving plate 44, and a rubber block 45.

[0038] The limiting rod 41 includes: a rotating receiving groove 411, a protruding rod 412, and a transmission gear 413.

[0039] The lower end of the limiting rod 41 is set on the limiting plate 22, which makes the limiting rod 41 more stable, which helps to improve the accuracy of obstacle avoidance prompts, allowing the elderly to grasp the road conditions ahead in a timely manner and ensuring the safety of the elderly.

[0040] The upper side wall of the limiting rod 41 is provided with a rotating receiving groove 411, and the rotating receiving groove 411 is symmetrically provided with protruding rods 412, namely protruding rod one 4121 and protruding rod two 4122, which are linked with the transmission gear 413.

[0041] There are two transmission gears 413, which are set in the rotating receiving groove 411, namely transmission gear one 4131 and transmission gear two 4132.

[0042] The transmission gear 4131 is located below the protruding rod 4121, and the two rotate together. The transmission gear 4131 meshes with the shaft tooth 3611 of the drive rod 361. When the drive rod 361 rotates clockwise, it drives the transmission gear 4131 to rotate, and the transmission gear 4131 drives the protruding rod 4121 to rotate.

[0043] The transmission gear 4132 is positioned above the protruding rod 4122, and both rotate together. The sidewall of the transmission gear 4132 meshes with the shaft tooth 3621 of the driving rod 362. When the driving rod 361 rotates counterclockwise, it drives the driving rod 362 to rotate counterclockwise. The driving rod 362 drives the transmission gear 4132 to rotate, and the transmission gear 4132 drives the protruding rod 4122 to rotate.

[0044] Two compressed airbags 42 are symmetrically arranged outside the limiting rod 41. A movable plate 44 is provided at the upper end of the plate, and its outer wall is attached to the inner wall of the support rod 21. A connecting groove 421 is provided on its inner side, and a small airbag 43 is provided in the connecting groove 421. The compressed airbag 42 and the small airbag 43 are connected. When the protruding rod 412 squeezes the small airbag 43, the gas inside the small airbag enters the compressed airbag 42, causing the upper end of the compressed airbag 42 to bulge, which causes the movable plate 44 to move upward. When the protruding part of the protruding rod 412 moves away from the small airbag 43, the gas in the bulging part of the compressed airbag 42 returns to the small airbag 43, which causes the movable plate 44 to return to its original position. During the continuous rotation of the protruding rod 412, the protruding rod 412 intermittently squeezes the small airbag 43, causing the movable plate 44 to move up and down intermittently.

[0045] The lower end of the rubber block 45 is connected to the moving plate 44, and the upper end is set in the limiting groove 12. After the controller 33 judges the direction and distance of the obstacle, it causes the drive rod 361 to rotate clockwise or counterclockwise, which drives the protruding rod 412 on the side with the obstacle to rotate continuously, causing the moving plate 44 to move up and down, so that one side of the rubber block 45 is in a vibrating state. When the elderly hold the handle 1, they can feel the vibration of one side of the rubber block 45 and know that the obstacle in front is located on one side. At the same time, the rotation speed of the protruding rod 412 is different according to the distance of the obstacle, which means that the vibration frequency of the rubber block 45 is different.

[0046] like Figure 10-11 As shown, the stabilizing device 5 includes: a rotating rod 51, a movable seat 52, and a base 53.

[0047] The upper end of the rotating rod 51 is set at the bottom of the positioning plate 23. It rotates under the drive of power. During the rotation, the positioning plate 23 supports and limits it, so that the rotating rod 51 rotates stably and ensures the accuracy of its rotation.

[0048] The movable seat 52 is nested on the rotating rod 51, and multiple hydraulic rods 521 are equidistantly arranged on its side wall. When the rotating rod 51 rotates, the movable seat 52 moves vertically, which in turn drives the hydraulic rods 521 to move.

[0049] The base 53 is located at the lower end of the rotating rod 51. Together with the positioning plate 23, it limits the rotation of the rotating rod 51, so that the rotating rod 51 rotates stably, which helps to improve the adjustment accuracy of the stabilizing device 5.

[0050] The base 53 includes: a telescopic rod 531 and a balance seat 532.

[0051] The telescopic rods 531 are multiple in number and are arranged at equal intervals in a ring on the side wall of the base 53. The upper wall of the telescopic rods 531 are connected to the lower end of the hydraulic rods 521. When the hydraulic rods 521 move, they drive the telescopic rods 531 to move horizontally.

[0052] The balance seat 532 is located on the outside of the telescopic rod 531 and serves to assist the support device 2. When the distance between the balance seat 532 and the base 53 is adjusted, the stabilizing device 5 can provide a larger support angle. At the same time, the cooperation between the hydraulic rod 521 and the telescopic rod 531 makes the bottom of the cane more stable, provides greater assistance to the elderly, and improves the stability of the elderly when going up and down stairs.

[0053] The working principle of this utility model: When obstacle avoidance detection and obstacle avoidance prompts are activated, the controller 33 judges the direction and distance of the obstacle by comparing the horizontal and vertical data of each set, and issues commands to the voice module 35 and the obstacle avoidance device 4. The voice module 35 then provides obstacle prompts, and the rubber block 45 at the location of the obstacle avoidance device 4 vibrates continuously, allowing the elderly person to obtain the specific location of the obstacle at the handle 1, ensuring that the elderly person avoids the obstacle in time. Furthermore, the closer the elderly person is to the obstacle, the higher the vibration frequency of the rubber block 45 becomes, allowing the elderly person to accurately understand the distance of the obstacle through perception, ensuring that the elderly person avoids the obstacle in time. When the elderly need to continue climbing or going up stairs, the obstacle avoidance detection is turned off, and the stabilization device 5 is adjusted by rotating block 232, so that the cane provides a more stable support effect and improves the assistance effect for the elderly. When the cane is hit or an accident occurs, and the finger is placed on the touch sensor 13, the controller 33 receives the signal and activates the warning mode. At this time, the camera module 32 acquires an image and transmits the image to the controller 33. The controller 33 performs joint positioning by judging the image and the Beidou positioning module 34, and sends the current location and surrounding environment to the guardian's mobile phone, so that the guardian can understand the current situation of the emergency encountered by the elderly and make a human judgment on whether to call the alarm.
