Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
The utility model discloses an ultrasonic wave blind guiding walking stick can perceive the peripheral static barrier and the barrier of motion, in time provides barrier information for the blind person to give the blind person certain direction, thereby improved the security that the blind person walked.
As shown in fig. 1, in an embodiment, the ultrasonic blind guiding crutch of the present invention includes a crutch 1, at least one ultrasonic sensor 2, a universal wheel 3, a driving motor 4 and a control module 5.
The crutch 1 can be made of plastic or hollow metal materials, so that the weight of the blind can be reduced.
The ultrasonic sensor 2 is used for detecting whether an obstacle exists in the periphery. Specifically, the ultrasonic sensor 2 is a sensor that converts an ultrasonic signal into another energy signal (typically, an electric signal). Ultrasonic waves are mechanical waves with a vibration frequency higher than 20 kHz. It has the features of high frequency, short wavelength, less diffraction, high directivity, directional propagation, etc. The penetration of ultrasonic waves into liquids and solids is great, especially in sunlight-opaque solids. Ultrasonic waves hitting impurities or interfaces can generate significant reflection to form reflection echoes, and hitting moving objects can generate Doppler effect. The ultrasonic sensor is widely applied to the aspects of industry, national defense, biomedicine and the like.
In an embodiment of the present invention, the number of the ultrasonic sensors 2 is 1 to 4. When the number of the ultrasonic sensors 2 is multiple, the ultrasonic sensors can be uniformly arranged around the crutch 1.
The universal wheel 3 is arranged at the bottom of the crutch 1.
In an embodiment of the present invention, the universal wheel 3 adopts a comet model.
The driving motor 4 is connected with the universal wheel 3, is arranged on the crutch 1, and is used for driving the universal wheel 3 to rotate.
The control module 5 is connected with the ultrasonic sensor 2 and the driving motor 4 and used for controlling the driving motor 4 to drive the universal wheel 3 to turn to the direction of the obstacle when the ultrasonic sensor 2 detects the obstacle. Specifically, when the ultrasonic sensor 2 detects that an obstacle exists around, the control module 5 controls the driving motor 4 to drive according to the direction of the obstacle, and drives the universal wheels 3 to turn to the direction of the obstacle, so that the blind is reminded that the obstacle exists in the direction and the blind needs to avoid walking.
In an embodiment of the present invention, the control module 5 is a single chip microcomputer.
In an embodiment of the present invention, the ultrasonic blind guiding crutch of the present invention further includes a power supply, and the control module 5 and the driving motor 4 are connected to each other, for supplying power to the control module 5 and the driving motor 4. Preferably, the power supply adopts dry batteries or storage batteries.
In an embodiment of the present invention, the ultrasonic blind guiding crutch of the present invention further includes a switch, and the power supply is connected to the switch for controlling the power supply to be turned on and off. Through setting up the switch, can open or close ultrasonic sensing and lead blind function. After the switch is closed, the ultrasonic blind-guiding crutch of the utility model can be used like the common blind-guiding strange shape.
In an embodiment of the present invention, the switch is disposed at the handle of the crutch, so as to facilitate the operation of the blind. Preferably, the switch is a push button switch.
In conclusion, the ultrasonic blind guiding crutch of the utility model does not need to frequently swing the blind guiding crutch to detect objects, and is lighter and more convenient; the blind person can be guided to avoid the barriers by detecting the front barriers within a set distance through ultrasonic waves and giving a certain guide to the blind person, and the walking safety of the blind person is improved. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
