Space assist device with active sensing and warning functions

Abstract

This invention provides a space assistance device with active sensing and warning functions for a user to carry. The space assistance device includes a control unit, a detection module, and a warning module. The detection module is used to detect a dynamic target within a preset range and output distance information to the control unit. When the control unit determines that the dynamic target has entered the preset range based on the distance information, it drives the warning module to emit a warning sound to simultaneously remind the user and the dynamic target. When the dynamic target has not entered the preset range, the warning module is controlled to remain silent. This allows the space assistance device to generate no environmental noise under normal circumstances and to activate a two-way collision avoidance warning only when necessary, providing a protection mechanism that combines concealment and safety.

Claims

1. A space assist device with active sensing and warning functions, which can be carried by a user (30), the space assist device (10) includes a control unit (11), a detection module (12) electrically connected to the control unit (11), and a warning module (13) electrically connected to the control unit (11), wherein the detection module (12) emits a detection signal in a predetermined direction and receives a reflected signal to detect a dynamic target (20) within a preset range (D1), and outputs distance information to the control unit (11), and the control unit (11) drives the warning module (13) to emit a warning sound when it determines that the dynamic target (20) has entered the preset range (D1) based on the distance information, and controls the warning module (13) to remain silent when the dynamic target (20) has not entered the preset range (D1).

2. The space assistance device with active sensing and warning functions as described in claim 1, wherein, The space assistance device (10) is a miniaturized design, which is hidden in a personal item (50) or a guide cane (40) of the user (30) without affecting the appearance of the personal item (50) or the guide cane (40).

3. The space assistance device with active sensing and warning functions as described in claim 2, wherein, The detection module (12) is an ultrasonic sensing module that calculates the distance information of the dynamic target (20) by emitting sound waves and receiving reflected sound waves.

4. The space assistance device with active sensing and warning functions as described in claim 3, wherein, The control unit (11) further changes the frequency or rhythm of the warning sound emitted by the warning module (13) according to the distance information, and the rhythm of the warning sound becomes more rapid when the distance information shows that the dynamic target (20) is closer to the user (30).

5. The space assistance device with active sensing and warning functions as described in claim 4, wherein, The radius of the preset range (D1) is approximately 1.5 meters.

6. The space assistance device with active sensing and warning functions as described in claim 5, wherein, The volume of the warning sound is set to be audible within a practical 2.5-meter range (D2) to simultaneously alert the user (30) and personnel located at the location of the dynamic target (20).
