Description

Technical Field

[0001] The present application belongs to the technical field of blind guide equipment, and in particular, relates to a wearable blind guide equipment. Background Art

[0002] The existing guidance solutions usually include guide sticks, wearable guide glasses, guide cars, guide mobile software, guide dogs, etc. Among them, guide sticks, wearable guide glasses, and guide cars are all local auxiliary guidance equipment, which can help the blind to detect obstacles around them to a certain extent; guide mobile software usually has global path planning and positioning functions, which can interactively receive the target location and plan the road, and remind or re-plan the route when the blind deviate from the planned road for a large range; specially trained guide dogs can usually perform global guidance and local obstacle perception between several familiar destinations, leading the blind to their destinations safely.

[0003] The existing guidance solutions usually include guide sticks, wearable guide glasses, guide cars, guide mobile software, guide dogs, etc. Among them, guide sticks, wearable guide glasses, and guide cars are all local auxiliary guide devices, which can only assist the blind to detect obstacles around them in the short distance. They lack the overall guidance function and require the blind to rely on their memory to determine their location and the route they will take. The guide mobile software usually has the function of global path planning and positioning, but lacks the ability to dynamically perceive the surrounding environment, such as pedestrians, vehicles, and debris on the blind path. Guide dogs generally face problems such as long training time, short service time, usually only being able to remember a limited number of routes, and high usage costs. In addition, guide dogs usually need to live with their users, which will also add some inconvenience to the users' lives. At present, there are only more than 200 guide dogs in service in China, which are very limited in role compared to the huge blind population. Summary of the invention

[0040] Please refer to Figure 1-Figure 3 A wearable blind guide device provided by an embodiment of the present application includes: an environment perception component, a control and power supply component controller module, a blind guide prompt component and a wearable body; the wearable body includes: a vest body 10; the environment perception 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 arranged on the outer surface of the vest body 10; the blind guide prompt component is arranged on the outer surface and / or 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 instructions to the blind guide prompt component according to the feedback information.

[0041] Specifically, the working process of the present application is as follows: the visual sensor module 20 and the laser sensor module 30 shoot, identify and measure the objects on the road ahead of the blind person, and send the processed data to the controller module 40. After receiving the signal, the controller module 40 performs path planning in real time through the built-in algorithm mechanism, and sends the result of the path planning to the guide prompt component. The guide prompt component prompts the blind user to walk by issuing sounds or action commands.

[0042] In one embodiment of the present application, the laser sensor module 30 includes: a laser radar 301, a laser radar protection cover 302 is provided on the laser radar 301, and the laser sensor module 30 is electrically connected to the controller module 40; the visual sensor module 20 includes: a camera 201, a camera protection cover 202 is provided on the camera 201, and the visual sensor module 20 is electrically connected to the controller module 40.

[0043] Specifically, in this embodiment, the number of laser radars 301 is one or more. For example, when it is set to two, a parallel setting can be adopted. This can not only improve the stability of the entire system (redundant design to prevent the entire guide equipment from failing when one laser radar fails), but also reduce blind spots.

[0044] It can be understood that corresponding protective covers are provided on the laser radar 301 and the camera 201 to prevent the laser radar and the camera from being damaged due to external forces.

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

[0046] It is understandable that since the blind can only perceive through sound or touch, the blind guide prompt component in this embodiment includes: a voice playback device 60 and / or a vibration device 70, so that the blind can perform corresponding obstacle avoidance walking through sound or vibration.

[0047] It should be noted that the voice playing device 60 and / or the vibration device 70 in the blind guide prompt component in this embodiment are optional, that is, the blind user can choose any one of the voice playing device 60 and / or the vibration device 70, or both of them can be installed. In this embodiment, the voice playing device 60 can be a headset or a loudspeaker, etc.

[0048] In one embodiment of the present application, the vibration device 70 includes a vibration motor; there are multiple vibration motors, which are horizontally arranged at the lower end portion of the inner surface of the vest body 10.

[0049] It can be understood that the vibration motor in this embodiment is arranged at the lower end portion of the inner surface of the vest body 10. Since the lower end portion of the vest body 10 covers the waist and abdomen, the vibration prompt effect is better at this position than at other parts.

[0050] As a preferred embodiment, the number of vibration motors can be set to 4, that is, one is set 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, it is only necessary to vibrate the vibration motor on the left.

[0051] In one embodiment of the present application, the wearable body further includes: a first connecting belt 80 and a first adjusting component 90, wherein the first connecting belt 80 is arranged at the lower end position 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 adapt to the wearing of blind people of different body shapes, the wearable body is generally set to be looser. Therefore, in order to make the wearable body fit the body better, in this example, a first connecting belt 80 and a first adjusting component 90 are provided on the side of the wearable body. The first adjusting component 90 is used to adjust the tightness of the wearable body so that the wearable body fits the body better.

[0053] As a preferred embodiment, the first connecting belt 80 and the first adjusting component 90 are arranged at the lower end of the vest body, so that the position of the first connecting belt 80 can form a covering structure with the vibration motor, which can not only adjust the tightness of the wearing body, but also make the vibration motor fit the body more closely, making it easier for blind users to receive the vibration signal sent by the vibration motor.

[0054] It should be noted that the first adjusting component 90 includes at least one of a magic buckle, a snap buckle, a Japanese buckle and a connecting buckle.

[0055] In one embodiment of the present application, the wearable body further includes: a second connecting strap 100 and a second adjusting component 110, the second connecting strap 100 and the second adjusting component are arranged at the upper end portion of the vest body; the second adjusting structure is used to adjust the tightness of the upper end of the vest body.

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

[0057] In one embodiment of the present application, the environment sensing component, the controller and the power supply component, the blind guide prompt component and the wearable body are detachably connected.

[0058] It is understandable that since each component often needs to be updated and the wearable body needs to be cleaned frequently when used outdoors for a long time, in this example, each module and the wearable body are provided with a detachable connection, which is convenient for subsequent updating of each module and can also meet the cleaning needs of the wearable body.

[0059] As a preferred embodiment, the wearable body is provided with reinforcing ribs or reinforcing plate structures at the positions of each module to ensure the stability of each module, and is provided with shock-absorbing pads or buffering devices to reduce the transmission of vibration and impact force generated by the blind person during exercise to the guide device, thereby preventing the guide device from loosening or being damaged due to vibration.

[0060] In one embodiment of the present application, the blind guide device further includes: a display module, which is connected to the controller module 40; the display module is used to visually display the control instructions and send the control instructions to the controller module 40.

[0061] Specifically, in some scenarios, for example, when a blind person needs to appear, the blind person's family members need a wearable guide device to send relevant instructions, but 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 present application provides a wearable blind guide device, which has the following beneficial effects:

[0063] 1. The structure of the present application is simple and easy to use, and it solves some of the shortcomings of current guide devices. The solution of the present application can intelligently identify road conditions and obstacle types, make corresponding judgments and processing for different environments and different obstacles, and generate detours or obstacle avoidance plans based on road conditions, and then send reminders and guidance to blind users through the guide prompt component, effectively solving the problem of blind people's travel navigation.

[0064] 2. The various module components of the present application are installed on the wearable vest body in a detachable manner, which is convenient for later maintenance and updating, and easy to clean the wearable vest body, thereby enabling long-term use.
