Description

Technical Field

[0001] This utility model relates to the field of guide cane technology, and in particular to a guide cane grip cover. Background Technology

[0002] Guide canes are devices used by visually impaired people to navigate or identify their surroundings. Existing AI-powered guide canes cannot meet the needs of blind people in cities who rely on tactile paving to find their way. They cannot provide feedback on the condition of the tactile paving, plan the most suitable route for the blind, record the blind person's walking process, or promptly inform relatives of the blind person's condition. Furthermore, current smart guide canes are expensive; the electronic components installed inside affect the cane's lifespan, and replacement costs are high.

[0003] A search revealed a Chinese patent with publication number CN211132019U, which discloses an intelligent ultrasonic guide cane, including a handle with a cane shaft and a button group mounted on the handle; wherein the button group includes a voice on / off button, a radar on / off button, a voice selection button, a guide cane on / off button, and a Bluetooth on / off button; and an ultrasonic sensor is mounted on the handle, and a controller is installed inside the handle.

[0004] To address the issues raised in the aforementioned technologies, such as the impact of installing electronic components inside the cane on its lifespan, the damage to the cane shaft after prolonged use, and the high cost and inconvenience of replacing the cane, a guide cane grip sleeve is proposed.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5 As shown, a guide cane grip sleeve includes a mounting sleeve 1 and a handle 2. One end of the mounting sleeve 1 has control components including a control module, a fixed positioning module, a fall detection module, and a wireless transmission module, which can control the electronic components inside the device. The mounting sleeve 1 and the handle 2 include an inner shell 13 and an outer rubber sleeve 14. The inner shell 13 is made of hard rubber, and the outer rubber sleeve 14 is made of soft material for easy touch and improved user experience. The inner shell 13 is fixedly connected to the inside of the outer rubber sleeve 14. Multiple double-ended lead screws 22 and a rotating shaft 16 are rotatably connected inside the inner shell 13. A limit ring 15 is fixedly connected inside the outer rubber sleeve 14. The limit ring 15 is made of soft rubber. One end of the double-ended lead screw 22 is threadedly connected to a fixing plate 23, and the other end of the double-ended lead screw 22 is fixedly connected to a worm gear 21. One end of the rotating shaft 16 is fixedly connected to multiple worms 17, and one end of the worm gear 21 meshes with the worm 17. One end of the rotating shaft 16 is fixedly connected to a drive nut 18.

[0031] When in use, the guide cane can be inserted into the opening below the mounting sleeve 1. The guide cane can be fixed by the limiting ring 15 first. Then, by rotating the drive nut 18, multiple worm gears 17 are rotated, and multiple double-ended screws 22 rotate simultaneously, causing multiple arc-shaped fixing plates 23 to clamp the inserted guide cane from both sides, achieving quick fixation and secure matching of guide canes of various diameters and shapes, saving usage costs.

[0032] In this embodiment, one end of the mounting sleeve 1 is fixedly connected to a player 6 and a light strip 7. The player 6 can provide voice navigation under the control of the control component. At the same time, it can issue an alarm when the guide cane with the device installed falls, and the light strip 7 will also emit a bright light to warn and call for help.

[0033] In this embodiment, a protective plate 9 is rotatably connected inside the mounting sleeve 1, and a camera 10 is fixedly connected to one end of the protective plate 9. The protective plate 9 can protect the camera 10 inside when not in use to prevent damage.

[0034] One end of the protective plate 9 is fixedly connected to a flipping shaft 11, and the other end of the flipping shaft 11 is slidably connected to a limiting plate 12. When in use, the protective plate 9 can be used normally simply by opening it. The angle of the protective plate 9 can be fixed by pulling open the limiting plate 12 and inserting one end of the limiting plate 12 into the external slot of the mounting sleeve 1.

[0035] In this embodiment, a plurality of control buttons 4 are fixedly connected to one end of the mounting sleeve 1. A button slot 8 is opened on one side of the control button 4. The control button 4 can control the electronic components on the mounting sleeve 1 and can be marked on the user terminal map. The user or his / her family can report the location of the tactile paving that is damaged or missing to the relevant departments so that the tactile paving can be modified and repaired in time. If a blind person falls or actively presses the control button 4, he / she can ask for help remotely and can also control the camera 10 to record video.

[0036] The buttons have 8 slots to help blind people distinguish them.

[0037] In this embodiment: When in use, the guide cane can be inserted into the opening below the mounting sleeve 1. At this time, the guide cane can be fixed by the limiting ring 15 first. Then, by rotating the drive nut 18, multiple worm gears 17 are rotated, and multiple double-ended screws 22 rotate simultaneously, causing multiple arc-shaped fixing plates 23 to clamp the inserted guide cane from both sides, so as to achieve quick fixation and firm matching of guide canes of various diameters and shapes, saving the cost of use;

[0038] The player 6 can provide voice navigation under the control of the control unit. It can also sound an alarm when the guide cane with the device is dropped. The light strip 7 will also emit a bright light to warn and call for help. The protective plate 9 can protect the camera 10 inside when not in use to prevent damage. When in use, you only need to open the protective plate 9 to use it normally. The angle of the protective plate 9 can be fixed by pulling open the limiting plate 12 and inserting one end of the limiting plate 12 into the external slot of the mounting sleeve 1.

[0039] Control button 4 can control the electronic components on the installation kit 1 and can be marked on the user terminal map. Users or their families can report the damaged or missing locations of the tactile paving to the relevant departments so that the tactile paving can be modified and repaired in a timely manner. If a blind person falls or actively presses control button 4, they can seek help remotely or control camera 10 to record video.

[0040] The buttons have 8 slots to help blind people distinguish them.

[0041] Example 2:

[0042] A guide cane grip sleeve, this embodiment is based on embodiment 1 with the following improvements, such as... Figure 1-5 As shown,

[0043] In this embodiment, a wrist strap 3 is fixedly connected to one end of the handle 2, and the wrist strap 3 can prevent the device from slipping out of the hand and falling off.

[0044] One end of the handle 2 is fixedly connected to a vibration motor 5, which can provide button feedback to help the user confirm whether effective control has been performed.

[0045] In this embodiment, a sprocket 19 is fixedly connected to one end of the rotating shaft 16, and a chain 20 is driven to the other end of the sprocket 19. The sprocket 19 and the chain 20 allow the device to be installed and fixed by rotating only one drive nut 18, making installation more convenient.
