Description

Technical Field

[0001] This utility model belongs to the technical field of guide equipment, and in particular relates to a wearable guide device. Background Technology

[0002] According to statistics, there are currently over 8 million blind people in China. Existing guidance solutions typically include guide canes, wearable guide glasses, guide vehicles, guide mobile apps, and guide dogs. Among these, guide canes, wearable guide glasses, and guide vehicles are all partial assistive devices that can help blind people detect nearby obstacles to a certain extent. Guide mobile apps usually have global path planning and positioning functions, interactively receiving target locations and planning routes, as well as providing reminders or replanning routes when the blind person deviates significantly from the planned route. Specially trained guide dogs can typically provide global guidance and local obstacle perception between several familiar destinations, leading the blind person safely to their destination.

[0003] Existing guide dog solutions typically include guide canes, wearable guide glasses, guide vehicles, guide mobile apps, and guide dogs. Guide canes, wearable guide glasses, and guide vehicles are all localized assistive devices, only helping blind people detect nearby obstacles and lacking global guidance capabilities. Blind people must rely on memory to determine their location and the route they will take. Guide mobile apps usually have global path planning and positioning functions, but lack the ability to dynamically perceive the surrounding environment, such as pedestrians, vehicles, and debris on tactile paving. Guide dogs generally face problems such as long training times, short service periods, the ability to memorize only a limited number of routes, and high operating costs. Furthermore, guide dogs usually need to live with their users, adding inconvenience to their lives. Currently, there are only about two hundred guide dogs in active service in China, which is very limited compared to the large blind population. Utility Model Content

[0040] Please refer to Figures 1-3 This utility model provides a wearable guide device for the blind, comprising: an environmental sensing component, a control and power supply component controller module, a guide prompt component, and a wearable body; the wearable body includes: a vest body 10; the environmental sensing component includes: a visual sensor module 20 and a laser sensor module 30; the control and power supply component includes: a controller module 40 and a power supply module 50; the visual sensor module 20, the laser sensor module 30, the controller module 40, and the power supply module 50 are disposed on the outer surface of the vest body 10; the guide prompt component is disposed on the outer surface and / or the inner surface of the vest body 10; the controller module 40 receives feedback signals from the visual sensor module 20 and the laser sensor module 30, and sends control commands to the guide prompt component according to the feedback information.

[0041] Specifically, the working process of this utility model is as follows: the visual sensor module 20 and the laser sensor module 30 photograph, identify and measure the distance of objects on the path of the blind person, and send the processed data to the controller module 40. When the controller module 40 receives the signal, it performs path planning in real time through the built-in algorithm mechanism and sends the path planning result to the guide prompt component. The guide prompt component prompts the blind user to walk by issuing sound or action commands.

[0042] In one embodiment of this utility model, the laser sensor module 30 includes: a laser radar 301, the laser radar 301 is provided with a laser radar protective cover 302, and the laser sensor module 30 is electrically connected to the controller module 40; the vision sensor module 20 includes: a camera 201, the camera 201 is provided with a camera protective cover 202, and the vision sensor module 20 is electrically connected to the controller module 40.

[0043] Specifically, in this embodiment, the number of lidar 301 is one or more. For example, when two are set, they can be arranged in parallel, which can improve the stability of the entire system (redundant design to prevent the entire guide device from failing when one lidar fails) and reduce blind spots.

[0044] It is understandable that protective covers are installed on both the lidar 301 and the camera 201 to prevent damage to the lidar and camera caused by external forces.

[0045] In one embodiment of this utility model, the guide prompt component includes: a voice playback device 60 and / or a vibration device 70; the voice playback device 60 is disposed on the outer surface of the vest body 10 and electrically connected to the controller module 40; the vibration device 70 is disposed on the inner surface of the vest body 10 and electrically connected to the controller module 40.

[0046] Understandably, since blind people can only perceive through sound or touch, the guide prompt component in this embodiment includes a voice playback device 60 and / or a vibration device 70, allowing blind people to navigate by sound or vibration.

[0047] It should be noted that the voice playback device 60 and / or vibration device 70 in the guide prompt component of this embodiment are optional, that is, blind users can choose either the voice playback device 60 or the vibration device 70, or both can be installed. In this embodiment, the voice playback device 60 can be headphones or a loudspeaker, etc.

[0048] In one embodiment of the present invention, the vibration device 70 includes a vibration motor; the number of vibration motors is multiple, and they are respectively horizontally arranged on the lower part of the inner surface of the vest body 10.

[0049] It is understood that the vibration motor in this embodiment is located at the lower end of the inner surface of the vest body 10. Since the lower end of the vest body 10 covers the waist and abdomen, the vibration prompting effect is better at this location compared to other parts.

[0050] As a preferred embodiment, the number of vibration motors can be set to 4, that is, one is provided on each of the front, back, left and right sides of the inner surface of the vest body 10. For example, when an obstacle is found on the road ahead and it is necessary to walk to the left to avoid the obstacle, only the vibration motor on the left side needs to be vibrated.

[0051] In one embodiment of the present invention, the wearable body further includes: a first connecting strap 80 and a first adjusting component 90, wherein the first connecting strap 80 is disposed at the lower end of the side of the vest body 10; and the first adjusting component 90 is used to adjust the tightness of the vest body.

[0052] Specifically, in order to accommodate blind people of different body types, the wearable body is generally designed to be relatively loose. Therefore, in order to make the wearable body fit the body better, in this example, a first connecting strap 80 and a first adjusting component 90 are provided on the side of the wearable body. The tightness of the wearable body is adjusted by the first adjusting component 90 to make the wearable body fit the body better.

[0053] In a preferred embodiment, the first connecting strap 80 and the first adjusting component 90 are located at the lower end of the vest body. This allows the first connecting strap 80 to form a covering structure with the vibration motor. This not only allows for adjustment of the tightness of the wearer but also makes the vibration motor fit the body more closely, making it easier for blind users to receive the vibration signals sent by the vibration motor.

[0054] It should be noted that the first adjusting component 90 includes at least one of the following: a magic buckle, a snap fastener, a D-ring, and a connecting buckle.

[0055] In one embodiment of the present invention, the wearable body further includes: a second connecting strap 100 and a second adjusting component 110, wherein the second connecting strap 100 and the second adjusting component are disposed on the upper part of the vest body; the second adjusting structure is used to adjust the tightness of the upper part of the vest body.

[0056] Specifically, in the embodiment, the second adjustment component 110 makes the upper part of the wearable body fit more stably and closely to the blind person's body, avoiding the wearable body from falling off due to the bumps caused by the blind person walking.

[0057] In one embodiment of this utility model, the environmental sensing component, the controller and power supply component, the guide prompt component, and the wearable body are detachably connected.

[0058] Understandably, since the various components often need to be updated and the wearable device is used outdoors for extended periods and requires frequent cleaning, in this example, the connection between each module and the wearable device is made detachable. This facilitates subsequent updates to each module and also meets the cleaning needs of the wearable device.

[0059] As a preferred embodiment, the wearable body is equipped with reinforcing ribs or reinforcing plates at the positions of each module to ensure the stability of each module, and is equipped with shock-absorbing pads or buffer devices to reduce the transmission of vibration and impact forces generated by blind people during movement to the guide equipment, and to prevent the guide equipment from becoming loose or damaged due to vibration.

[0060] In one embodiment of this utility model, the guide device further includes a display module, which is connected to the controller module 40; the display module is used to visualize control commands and send the control commands to the controller module 40.

[0061] Specifically, in certain scenarios, such as when a blind person needs to appear, the blind person's family needs to send relevant instructions using a wearable guide device. However, since the wearable guide device does not have an operation panel, in this example, a display module can be connected to the guide device to visualize the guide control instructions and send the guide control instructions to the controller module 40.

[0062] The wearable guide device for the blind provided by this utility model has the following advantages:

[0063] 1. This utility model has a simple structure and is easy to use, solving some of the shortcomings of current guide devices for the blind. The solution of this utility model can intelligently identify road conditions and obstacle types, make corresponding judgments and processing for different environments and different obstacles, and generate detour or obstacle avoidance plans according to road conditions. Then, it issues reminders and guidance to blind users through guide prompt components, effectively solving the problem of navigation for blind people.

[0064] 2. The various modules and components of this utility model are detachably installed on the main body of the wearable vest, which facilitates later maintenance and updates, and makes it easy to clean the main body of the wearable vest, thus enabling long-term use.

[0065] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0066] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
