Now, combined with various intelligent technologies, some blind canes can also have functions such as navigation, which can provide greater convenience for blind people to travel.

[0005] The blind cane itself is the basic carrier for realizing many functions, and the integrity of the blind cane plays a decisive role in the realization of its functions. However, due to visual defects, blind people are unable to effectively detect and maintain the blind cane, and relying on manual maintenance, there will inevitably be times of forgetting and omission. Once the blind cane is damaged but not discovered in time, it will pose a danger to the travel of blind people. Summary of the Utility Model

Detailed Description of the Invention

[0044] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] The present disclosure provides a blind stick, which includes a stick body, a light emitter, a light receiver and a controller. The stick body extends from one end to the other end. The light emitter is arranged at one end of the stick body and is used for emitting light. The light receiver is arranged at the other end of the stick body and is used for receiving the light emitted from the light emitter. The controller is communicatively connected to the light emitter and the light receiver, and is used for determining whether the stick body is bent based on whether the light receiver can receive the light emitted by the light emitter.

[0046] In an embodiment of the present disclosure, when the cane body is not damaged or bent, the light emitted by the light emitter is projected into the light receiver and received by the light receiver. After the cane body is damaged or bent, the light emitter and the light receiver are no longer on the original light path, resulting in the light emitted by the light emitter not being received by the light receiver. Thus, when the light emitter emits a light beam, the controller can determine whether the cane body is bent or damaged by detecting whether the light receiver receives the light, without manual detection. This not only avoids detection errors caused by the visual defects of the blind but also enables the determination of the safety situation of the blind by judging the state of whether the cane body is bent or damaged.

[0047] A blind cane is a tool for facilitating the travel of the blind. Generally, the blind use a blind cane to explore the road and support themselves to identify paths, obstacles, etc. Generally speaking, the integrity of the blind cane body is crucial for the blind.

[0048] Figure 1 The following is a schematic diagram of a blind cane structure shown according to an exemplary embodiment, as Figure 1 shown, the present disclosure provides a blind cane, including a cane body 1, a light emitter 11, a light receiver 12, and a controller 2. The cane body 1 extends from one end to the other end. The light emitter 11 is disposed at one end of the cane body 1 for emitting light. The light receiver 12 is disposed at the other end of the cane body 1 for receiving the light emitted from the light emitter 11. The controller 2 is communicatively connected to the light emitter 11 and the light receiver 12 for determining whether the cane body 1 is bent based on whether the light receiver 12 can receive the light emitted by the light emitter 11.

[0049] In an embodiment of the present disclosure, when the cane body 1 is not damaged or bent, the light emitted by the light emitter 11 can be directly projected into the light receiver 12, so that the light receiver 12 can receive the light emitted by the light emitter 11. Once the cane body 1 is bent or has other problems, the light receiver 12 will deviate from the light path of the light emitted by the light emitter 11, making the light receiver 12 unable to receive the light emitted by the light emitter 11. Thus, when the light emitter 11 emits light, the controller 2 can determine whether the cane body 1 is bent or damaged by detecting whether the light receiver 12 receives the light emitted by the light emitter 11. Specifically:

[0050] The light emitter 11 emits light, the light receiver 12 receives the light from the light emitter 11, and the cane body 1 is not bent;

[0051] The light emitter 11 emits light, the light receiver 12 does not receive the light from the light emitter 11, and the cane body 1 is bent.

[0052] In some embodiments, the light emitter 11 is a laser emitter that can emit laser light. The light receiver 12 is a laser receiver that can receive laser light.

[0053] Laser light has good penetrability, is more stable, and is not easily affected by ambient light.

[0054] The type and emission power of the laser light emitted by the laser emitter can be selected as needed, and the present disclosure does not limit this.

[0055] In some embodiments, as Figure 1 shown, the cane body 1 includes a ground - contact end 13 for contacting the ground and a holding end 14 for holding. The light emitter 11 is disposed at the holding end 14 to emit light towards the ground - contact end 13, and the light receiver 12 is disposed at the ground - contact end 13 to receive the light from the holding end 14.

[0056] In the embodiments of the present disclosure, when the light emitter 11 is disposed at the holding end 14 and the light receiver 12 is disposed at the ground - contact end 13, when using the blind cane, the light emitted by the light emitter 11 is emitted towards the ground, avoiding the situation where when the blind cane is bent due to an accident, the light emitted by the light emitter 11 is emitted upward and shines on the user and passers - by, thus improving the safety of using the blind cane.

[0057] If the light - emitting device and the light - receiving device are disposed outside the cane body 1, the light emitted by the light emitter 11 needs to propagate outside the cane body 1 and is easily affected by environmental factors such as thick smoke, thick fog, and obstacles. Once the light emitted by the light emitter 11 is blocked by thick smoke, thick fog, obstacles, etc., the light receiver 12 cannot receive the light emitted by the light emitter 11, thereby causing misjudgment.

[0058] Figure 2 is a schematic diagram of a blind - cane structure shown according to an exemplary embodiment. As Figure 2 shown, a cavity 15 is formed in the cane body 1 along the extending direction of the cane body 1, and the light emitter 11 and the light receiver 12 are disposed in the cavity 15.

[0059] In the embodiments of the present disclosure, when the light emitter 11 and the light receiver 12 are disposed in the cavity 15 of the cane body 1, the light emitted by the light emitter 11 propagates entirely within the cavity 15, eliminating the influence of external environmental factors of the cane body 1, avoiding misjudgment of whether the cane body 1 is bent or damaged, and improving the accuracy of monitoring the state of the cane body 1.

[0060] Figure 3 is a schematic diagram of a blind - cane structure shown according to an exemplary embodiment. As Figure 3 shown, a light groove 16 is formed in the circumferential side wall of the cane body 1 along the extending direction of the cane body 1, and the light emitted by the light emitter 11 propagates in the light groove 16.

[0061] In the embodiment of the present disclosure, by opening a light groove 16 on the side wall of the stick body 1, the light emitted by the light emitter 11 propagates in the light groove 16, which can reduce the influence of obstacles in the environment on the light propagation, thereby improving the stability of the light propagation, and finally improving the accuracy of monitoring the state of the stick body 1. In addition, the light groove 16 only needs to allow the light to pass through, and the light groove 16 can be made relatively shallow, with low processing difficulty and less damage to the strength of the stick body 1.

[0062] The cane body 1 of the blind cane is rarely damaged during use, but whether it is damaged by external force or due to aging, as long as it is damaged during use, it is very likely that the user will be injured. The user of the blind cane is a blind person, and he cannot observe and remember the surrounding scene when the blind cane is bent, which is not conducive to handling accidents.

[0063] Figure 4 FIG. 1 is a schematic diagram showing a structure of a blind stick according to an exemplary embodiment. Figure 4 As shown, the controller 2 is further used to send a first instruction when the stick 1 is bent, and the first instruction is used to instruct an electronic device used in conjunction with the blind stick to save images collected within a preset time period.

[0064] In the embodiment of the present disclosure, when the light transmitter 11 emits light, if the light receiver 12 cannot receive the light emitted by the light transmitter 11, it is determined that the stick body 1 is bent, and the controller 2 sends a first instruction to record the impact within a preset time period. The specific situation near the blind stick when the stick body 1 is bent can be saved, which is conducive to subsequent processing at other times.

[0065] For example, a blind stick may be bent because of a car accident. The blind stick is bent by the impact of the vehicle. At this time, the user of the blind stick is often injured. Recording the image at this time will help find the vehicle that caused the accident or clarify the responsibility for the accident.

[0066] In some embodiments, the preset time period may refer to a period of time before the cane 1 is bent, or a period of time after the cane 1 is bent, or a period of time from a period of time before the cane 1 is bent to a period of time after the cane 1 is bent, and the present disclosure does not limit this.

[0067] In some embodiments, the controller 2 may include a camera for acquiring images. During the use of the cane, the camera continuously acquires the image in front of the camera and caches or stores it. It can store images during the entire working time from power on to power off, or it can only cache images within a preset time length (such as 2 minutes) and overwrite the earliest image with the latest image. When the controller 2 sends a first instruction to save images within a preset time period, the cached images are stored and no longer overwritten.

[0068] Figure 5 shows a schematic structural diagram of a controller of a blind cane according to an exemplary embodiment, as Figure 5 shown. The image of the blind cane can also be sourced from other devices. For example, a mobile terminal with a camera can be connected to the controller 2 of the blind cane to simplify the controller 2 and reduce costs. This mobile terminal can be a mobile phone. For example, a control chip 25 and a battery 26 are provided inside the controller 2, and a first connecting wire 22 connected to the control chip 25 is provided. One end of the first connecting wire 22 away from the control chip 25 is provided with a first plug 23, and the first plug 23 is used to connect to the mobile terminal. Of course, the controller 2 can also be wirelessly connected to the mobile terminal, such as using technologies like Bluetooth.

[0069] In some embodiments, the acquired image can be a video or consecutive captured pictures.

[0070] In some embodiments, the connection between the controller 2 and the light emitter 11 and the light receiver 12 can be a wired connection or a wireless connection.

[0071] In some embodiments, the controller further includes a first gyroscope and an acceleration sensor. The first gyroscope is used to obtain the user's movement direction; the acceleration sensor is used to obtain the user's movement acceleration; the controller determines whether the user has fallen based on the user's movement direction obtained by the first gyroscope and the user's movement acceleration obtained by the acceleration sensor.

[0072] In the embodiments of the present disclosure, due to the user's visual impairment, the user generally does not suddenly change the movement direction and suddenly accelerate. When it is detected that the blind cane suddenly turns and accelerates, it is very likely that the user has fallen or other situations have occurred. Based on this, a relatively accurate judgment of the user's state is made.

[0073] In some embodiments, a threshold value of the direction change angle and acceleration is preset. When both the acquired direction change angle and acceleration are greater than the preset threshold value, it is determined that the user has fallen.

[0074] It should be noted that falling is just a representative statement and also includes various accidental situations such as the user falling, colliding, etc.

[0075] In some embodiments, the controller may not be provided with a first gyroscope and an acceleration sensor, but instead call the gyroscope and acceleration sensor in the mobile terminal that cooperates with the controller.

[0076] In some embodiments, the controller is further used to send a second instruction in the case of the user falling, and the second instruction is used to instruct the electronic device used in cooperation with the blind cane to save the images collected within a preset time period.

[0077] In an embodiment of the present disclosure, when it is determined that the user has fallen, saving the image can record the process of the fall, which is convenient for follow-up processing.

[0078] In some embodiments, the blind stick may also have a camera, and the second instruction instructs to save the image collected by the camera of the blind stick.

[0079] In some embodiments, as Figure 5 shown, the controller 2 includes a housing 21 forming an outer contour. The light emitter 11 is disposed within the housing 21, and the housing 21 is provided with a through hole 211 penetrating through the inside and outside of the housing 21 for the light emitted by the light emitter 11 to pass through.

[0080] In an embodiment of the present disclosure, disposing the light emitter 11 within the housing 21 of the controller 2 can protect the light emitter 11 and prevent it from being damaged. Moreover, the distance between the light emitter 11 and the controller 2, especially the control chip 25, is shortened, which is beneficial to reducing the use of wires.

[0081] To facilitate the travel of the blind, it is not enough for the blind stick to only play the role of exploring the road to identify the path and obstacles, and it cannot help the blind to actively plan the route and navigation. To solve this problem, the following embodiments are specifically proposed:

[0082] In some embodiments, the blind stick further includes a positioning module. The positioning module has a satellite positioning module and a geomagnetic sensor, and the satellite positioning module and the geomagnetic sensor cooperate to determine the navigation direction and the travel route.

[0083] In an embodiment of the present disclosure, the satellite positioning module and the geomagnetic sensor can help the user of the blind stick plan the navigation route, eliminating the need for the user to find and plan the route by themselves, reducing the travel difficulty of the user of the blind stick, and the travel range of the user of the blind stick does not have to be limited to the routes they are familiar with, thus expanding the travel range of the user of the blind stick.

[0084] Even after the navigation direction and the travel route are determined for the user, the user may still deviate from the route during actual travel. There are many reasons for this, such as the user having a poor sense of direction and deviating during normal walking, or the route itself being curved or skewed. In such cases, the user is easily in danger due to deviating from the travel route.

[0085] In some embodiments, the positioning module further includes an acceleration sensor. After using the satellite positioning module and the geomagnetic sensor to cooperate to determine the navigation direction and the travel route, the satellite positioning module, the geomagnetic sensor, and the acceleration sensor cooperate to calibrate the travel route.

[0086] Calculate the current orientation through the geomagnetic sensor and the acceleration sensor, and calibrate it with the data of the satellite positioning module, so as to determine the displacement deviation of the user and improve the safety of the user during walking.

[0087] In some embodiments, the positioning module can be set in the controller 2 and be a part of the controller 2.

[0088] In some embodiments, the controller 2 can call the positioning module of the external mobile terminal 4, and the controller 2 itself does not set a separate positioning module, which simplifies the controller 2, reduces costs, and effectively utilizes the resources of the mobile terminal 4 at the same time.

[0089] In some embodiments, the controller 2 can call the positioning module of the external mobile terminal 4, including the call of hardware and the call of software (such as the call of navigation and map software).

[0090] In some embodiments, the satellite positioning module can refer to the global navigation satellite system, such as GPS, Beidou, etc.

[0091] In some embodiments, the blind stick further includes an earphone, and the controller is communicatively connected to the earphone, and describes the surrounding environment to the user in a voice manner through the earphone, so that the user can make accurate judgments and responses to the surrounding environment, especially in scenarios with complex situations such as intersections and near construction sites.

[0092] In some embodiments, obtain the image in front of the camera through the camera, use image recognition to accurately identify the state of the sidewalk signal light, the zebra crossing and the obstacle state, use YoloV7-tiny as the training parameter to detect the zebra crossing and the signal light (red, green, none), and describe the above environmental information and geographical orientation to the user in a voice manner through the earphone.

[0093] In some embodiments, obtaining the image and image recognition can be completed by the camera and hardware separately set by the controller itself, or can rely on the external mobile terminal to complete. Generally speaking, it can rely on the external mobile terminal (such as a mobile phone) to complete, because image recognition requires the deployment of the NCNN framework for real-time detection, and its computing volume is large, and it has high requirements for hardware, and the hardware of the controller itself often cannot meet the requirements.

[0094] During the interaction between the blind stick and the user, it is necessary to give a real-time reminder of the user's walking direction to prevent the user from deviating from the direction. If voice prompts are used, the external voice will affect the surrounding people, and using earphones will affect the user's reception of environmental sounds. To solve this problem, the following embodiments can be adopted:

[0095] Figure 6 FIG. is a schematic diagram of a blind stick structure shown according to an exemplary embodiment. Figure 7Schematic diagram showing the connection relationship between the vibration belt 3 of a blind cane and the controller 2 according to an exemplary embodiment, as Figure 6 , Figure 7 shown. The blind cane further includes a vibration belt 3 communicatively connected to the controller 2. A plurality of vibration components 31 are circumferentially arranged on the vibration belt 3.

[0096] In an embodiment of the present disclosure, by providing the vibration belt 3 with the vibration components 31, the direction can be guided to the user in a vibrating manner. For the side to travel, the vibration module on that side vibrates.

[0097] For example, the vibration belt 3 has four vibration components 31 arranged circumferentially and uniformly. When worn, they respectively correspond to the front, rear, left, and right directions. When the blind cane is navigating, the controller 2 sends a signal to the right, and the right vibration component 31 vibrates; sends a signal to the left, and the left vibration component 31 vibrates; sends a signal to the rear, and the rear vibration component 31 vibrates. When crossing the road, it sends a signal to the front, and the front vibration component 31 vibrates; sends a stop signal, and all four vibration components 31 vibrate.

[0098] Of course, the number of vibration components 31 on the vibration belt 3 can also be other numbers, such as 8, so as to make the indication of direction more accurate.

[0099] In some embodiments, the vibration belt 3 further includes a second gyroscope (not shown in the figure), and the second gyroscope is used to determine the wearing posture of the vibration belt 3.

[0100] The wearing posture refers to the inside and outside, front and rear, left and right, positive and negative directions, etc. when the vibration belt 3 is worn.

[0101] In an embodiment of the present disclosure, due to visual defects, it is very difficult for the user to wear the vibration belt 3 correctly according to the preset wearing posture. Once worn incorrectly, it will cause the direction actually indicated by the vibration component 31 to be inconsistent with or even opposite to the target direction, bringing danger to the user. By providing a second gyroscope in the vibration belt 3, the movement trajectory of the vibration belt 3 is obtained by the second gyroscope, the wearing posture of the vibration belt 3 is judged, and then the vibration components 31 are adaptively adjusted at the control level, so that no matter how the user wears the vibration belt 3, the vibration belt 3 can correctly indicate the direction, improving safety.

[0102] In some embodiments, the functions of the first gyroscope and the second gyroscope can be realized by one gyroscope as long as the relevant control methods are adjusted.

[0103] In some embodiments, the vibration belt is set to be circumferentially telescopic.

[0104] In an embodiment of the present disclosure, the vibrating belt 3 is set to be circumferentially stretchable, so that the vibrating belt 3 can be applied to more wearing positions. For example, it can be worn on the wrist, arm, waist or other positions. The user can choose according to their own needs.

[0105] In some embodiments, as Figure 7 shown, the vibrating belt 3 and the controller 2 can be connected by wire. For example, a second connecting wire 24 is provided to transmit current and signals through the second connecting wire 24. Alternatively, they can also be connected wirelessly, such as via Bluetooth or the like.

[0106] Figure 8 is a schematic structural diagram of a vibrating belt shown according to an exemplary embodiment. As Figure 8 shown, the vibration assembly 31 includes a flexible layer 311 provided on the vibrating belt 3 and a vibration motor 312 provided on the flexible layer 311.

[0107] In an embodiment of the present disclosure, by arranging the vibration motor 312 on the flexible layer 311, it is possible to avoid excessive vibration stimulation of the user by the vibration motor 312 and cause discomfort. At the same time, it also has the effect of reducing vibration noise.

[0108] In some embodiments, the flexible layer 311 can be provided inside the vibrating belt 3 or on the surface of the vibrating belt 3.

[0109] In some embodiments, the flexible layer 311 can be made of sponge material, or can be made of other materials or material combinations.

[0110] In some embodiments, the vibration motor 312 can be provided inside the flexible layer 311 or on the surface of the flexible layer 311.

[0111] In some embodiments, the vibration motor 312 can be an eccentric rotation motor, a piezoelectric vibration motor, or other elements that can generate vibration.

[0112] When a blind person wears the vibrating belt, it is difficult to distinguish the front and back directions of the vibrating belt. If the vibrating belt is worn in the wrong direction, it will bring great danger to the user. To avoid this situation, the following embodiments can be adopted.

[0113] Figure 9 is a schematic structural diagram of a vibrating belt shown according to an exemplary embodiment. As Figure 9 shown, the vibrating belt 3 is provided with a special-shaped structure 32 for determining the wearing direction of the vibrating belt 3.

[0114] In an embodiment of the present disclosure, using the special-shaped structure 32 for the user to distinguish the direction of the vibrating belt 3 is beneficial for the user to correctly wear the vibrating belt 3 and improve the safety of the user using the blind cane to navigate and travel.

[0115] In some embodiments, the shaped structure 32 can be a concave structure, a convex structure, or a combination of a concave structure and a convex structure.

[0116] For example, the shaped structure 32 is arranged on the outer peripheral side wall of the vibration band 3, the vibration band 3 is worn on the wrist, the shaped structure 32 is aligned with the artery at the wrist, and the direction of the vibration band 3 is correct.

[0117] Figure 10 FIG. shows a schematic diagram of the usage state of a blind stick according to an exemplary embodiment, as Figure 10 shown, the controller 2 is arranged on the stick body 1, and a structure for fixing the mobile terminal 4 is arranged on the controller 2. The vibration band 3 can be worn at various positions. Figure 10 Two cases of wearing the vibration band 3 on the wrist and the arm are exemplarily shown in FIG.

[0118] Of course, the controller 2 is not necessarily fixed to the stick body 1. In some embodiments, the controller 2 can be arranged separately or detachably arranged with the stick body 1.
