Description

Technical Field

[0001] The utility model belongs to the technical field of blind canes, and particularly relates to a multifunctional intelligent blind cane. Background Art

[0002] At present, the ways for blind people to travel rely on ordinary blind canes, guide dogs or the leading of guardians. Ordinary blind canes require the absolute perception of blind people to judge the direction of the road and need to walk on special blind paths. In the case where the blind path is occupied, it is very difficult to distinguish the road; guide dogs need to be specially trained to play the role of guiding, and their training costs are relatively high, and in some occasions, guide dogs are not suitable to appear; the leading of guardians requires the guardians to accompany at any time, which greatly wastes manpower and time. With the aggravation of social aging, there are generally many elderly people with memory loss and inconvenient legs and feet, and their travel has attracted extensive attention from all walks of life. Out of concern for blind people and the elderly, it is particularly important to develop a convenient and user-friendly travel tool.

[0003] For example, the Chinese patent of the prior art CN220327652U discloses a blind cane device, which includes a grip rod, a first rod, a connecting rod and a second rod. The bottom end of the grip rod is welded with the first rod, and a plurality of connecting rods are inserted and installed at the bottom of the first rod. The bottom of the last connecting rod is inserted and installed with the second rod. The bottom end of the second rod is symmetrically welded with fixing plates, and rollers are installed between the two fixing plates. A battery power supply chamber is opened at the inner top of the grip rod, a sealing cover is installed at the top end of the grip rod, an anti-detachment rope is installed at the top end of the sealing cover, a control switch is installed on one side of the outer wall of the grip rod, annular embedding grooves are equidistantly opened on the outer wall of the first rod, and annular LED lamp belts are installed inside the annular embedding grooves.

[0004] Compared with the traditional ordinary cane, although the existing intelligent cane has added functions such as lighting, it still lacks functions of user-friendly care. For example, it cannot help the elderly, especially blind people, to find their way, cannot prompt the elderly or blind people of obstacles or water obstacles ahead, and cannot achieve automation and intelligence, making it inconvenient to use.

[0034] Inside the main control housing 3, there are a first main control board 10, a second main control board 20, a power module 30, and functional components. The first main control board has communication and positioning functions. In this embodiment, the first main control board uses a standard component such as SIM7600CE-T 4G (LTE) Shield, which is an Arduino expansion board integrating 2G / 3G / 4G and GNSS navigation technologies, supporting 4G communication and GNSS navigation technology, and having better positioning effects; the second main control board is a conventional Arduino main control board.

[0035] The functional components include a headphone module 110, a buzzer module 120, an ultrasonic sensor 220, a light sensor 230, a voice recognition module 120, and a voice playback module 130. The functional components are all connected to the second main control board; among them, the headphone module wirelessly connects the headphones of the blind user to the cane. In actual use, the voice control instructions sent by the blind person through the headphones are transmitted by the voice recognition module to the first main control board, and then the corresponding prompts are played by the voice playback module; the ultrasonic sensor detects the obstacles around the blind person when using the cane, and gives an alarm prompt through the buzzer module to remind the blind person to pay attention to detouring to avoid obstacles, and the light sensor detects the surrounding environmental light conditions when the blind person uses the cane.

[0036] Inside the button housing 2, there is a button switch assembly 310 for controlling the power module 30. As a standard component, there are three buttons on the button switch assembly connected to the first main control board, which are used in conjunction with the voice recognition module and the voice playback module to control sending text messages and having conversations.

[0037] An RGB light strip 240 is provided on the cane body 4. The RGB light strip can be adhesively fixed to the outer wall of the cane body. A humidity sensor 250 is provided at the bottom of the cane body 4. The RGB light strip 240 and the humidity sensor 250 are both connected to the second main control board 20. The RGB light strip is used in conjunction with the light sensor. When the light sensor detects that the surrounding environmental light conditions are poor when the blind person uses the cane, the second main control board controls the RGB light strip to light up and flash to warn people around that there is a blind person walking. The humidity sensor detects the ground humidity condition. If the humidity value is high, an alarm prompt is given by the buzzer module to remind the blind person to pay attention to avoiding.

[0038] The power module 30 supplies power to the first main control board 10, the second main control board 20, the functional components, the RGB light strip 240, and the humidity sensor 250.
