Description

Technical Field

[0001] This utility model relates to the field of assistive device technology, and in particular to an assistive device for blind people to travel. Background Technology

[0002] Although the city's sidewalks are equipped with tactile paving, the frequent maintenance of water pipes, gas pipes, and sewage pipes often damages the roads, resulting in the tactile paving being intermittent. In addition, many city sidewalks are filled with parked non-motorized vehicles, which brings great obstacles and troubles to the blind people's travel.

[0003] When blind people travel, they usually rely on canes or guide dogs for assistance. However, due to the complex road conditions, these two methods can lead to problems with delayed response in special situations, and the safety of blind people traveling cannot be effectively guaranteed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a travel assistance device for the blind. By hanging the device equipped with front and rear cameras on the shoulder, it can obtain road information from all directions during the journey, ensuring the safety of the blind when traveling.

[0005] This utility model provides a travel assistance device for the blind, including a front host and a rear camera physically connected to the front host. The rear camera is used to collect road information behind the blind person while traveling. The front-end host is equipped with an MCU chip and a GPS chip, and the GPS chip and the MCU chip are connected; the front-end host is also equipped with a front-end camera; The GPS chip is used to identify the current geographical location of the blind person, and the front-facing camera is used to collect road information during the blind person's movement and send the road information to the MCU chip so that the MCU chip can plan a route for the blind person based on the collected road information.

[0006] Optionally, the rear camera is connected to the front-facing unit via a shoulder strap.

[0007] Optionally, the front-end host also has a built-in IoT card connected to the MCU chip for periodically upgrading the maps and programs stored inside the front-end host.

[0008] Optionally, the front-end host is also equipped with a voice device for providing voice prompts to blind users.

[0009] Optionally, the bottom of the front host is also provided with a magnetic charging port for charging via a magnetic charger.

[0010] This utility model provides a travel assistance device for the blind. By setting a front camera and a rear camera on the device and connecting the two camera devices through a shoulder strap, the blind person can obtain not only the road conditions in front of them but also the road conditions behind them while traveling. This achieves comprehensive acquisition of road information and further ensures the safety of the blind person's travel. Attached Figure Description

[0011] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments of this utility model will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on the content of the embodiments of this utility model and these drawings without creative effort.

[0013] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] This utility model provides a travel assistance device for the blind, including a front host 1 and a rear camera 2 physically connected to the front host.

[0015] The front-end host is equipped with an MCU chip 11, a GPS chip 12, and an IoT card 13. The GPS chip and the IoT card are respectively connected to the MCU chip.

[0016] Furthermore, the aforementioned front-mounted unit is also equipped with a front-facing camera 14, a voice device 15, and a wireless charging module 16.

[0017] The GPS chip is used to identify the current geographical location of the blind person. The front and rear cameras are used to collect real-world road information in front of and behind the blind person during their journey. The collected real-world road information is sent to the MCU chip. The MCU chip analyzes and compares the real-world road information with the pre-stored electronic map. On the one hand, it guides the blind person to a specific route. On the other hand, it predicts obstacles on the tactile paving and plans new routes.

[0018] The auxiliary device stores electronic maps via an IoT card, which can also automatically upgrade the map and device software periodically, and remind the user via voice before the upgrade.

[0019] The aforementioned voice device can be a loudspeaker, used to guide blind people through the passage using voice during movement.

[0020] To facilitate user operation, the auxiliary device in this embodiment is charged via a wireless charging module, or for example, via a magnetic charger. When the battery is low, it will automatically remind the user via a voice device.

[0021] See further Figure 2 When using this assistive device, the user wears it on their body via a shoulder strap, with the front unit in front and the rear camera behind. As the user moves, the front and rear cameras capture real-time images. When the camera clearly shows tactile paving on the road, a small speaker guides the blind person; when there are obstacles on the tactile paving, the device automatically analyzes and determines an obstacle avoidance route and guides the blind person through.

[0022] When the camera cannot identify the tactile paving or the tactile paving is intermittent in the road, the MCU chip automatically generates a complete tactile paving or a complete walking route, and a small speaker guides the blind person through.

[0023] When a blind person crosses an intersection, the camera automatically analyzes the traffic lights and the flow of vehicles and pedestrians on the pedestrian walkway, automatically generates a walking route, and a loudspeaker guides the blind person through.

[0024] The blind travel assistance device provided by this utility model has no physical buttons other than the power button, resulting in a simple structure. The device uses wireless charging and is fully voice-controlled, making it convenient for blind users. It can provide voice prompts for time, weather, navigation assistance, remote location services, and low battery reminders. Internal program upgrades are fully automatic, requiring no secondary confirmation or operation, greatly facilitating user operation.

[0025] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
