Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0041] Currently, various transportation vehicles are equipped with pedals for carrying users, with sliding rollers at both ends of the pedals, drive motors and power supplies inside the pedals, as well as remote control rods, various sensors, and gyroscopes on the pedals. Users manually control the remote control rod to trigger the motor to control the movement of the rollers or detect the body movements of the users through various sensors and gyroscopes to control the motor to drive the rollers to move.

[0042] However, the currently commonly used various personal transportation vehicles have the following technical problems: both manual operation control and detection operation control consume a large amount of electric energy, and the electric energy stored in the power supply is limited, resulting in a short usage time and low endurance of various transportation vehicles.

[0043] To solve the above problems, a human body intelligent walker provided by an embodiment of the present application will be introduced and described in detail through the following specific embodiments.

[0044] Refer to Figures 1-4 , which shows a side view of a human body intelligent walker provided by an embodiment of the present invention when standing upright, a side view of a human body intelligent walker provided by an embodiment of the present invention when bent, a side view of a human body intelligent walker provided by an embodiment of the present invention when assisting in movement, and a front view of a human body intelligent walker provided by an embodiment of the present invention when assisting in movement.

[0045] Among them, as an example, the human intelligent walker may include:

[0046] A waistband 1, two generators 2, two walking footrests 3, and a controller 4.

[0047] Among them, the waistband 1 is strapped to the user, the waistband 1 is respectively connected to the two walking footrests 3, the two walking footrests 3 are respectively strapped to the sides of the user's feet, the two generators 2 are respectively arranged on the waistband 1, each generator 2 is respectively connected to a walking footrest 3, and the controller 4 can be arranged on the front of the waistband 1.

[0048] In an embodiment, the controller 4 may be provided with a camera, several sensors, a gyroscope, a control circuit, etc., and can be used to control the startup and shutdown of the walking footrest 3.

[0049] Refer to Figures 1-4 , a driving motor 5 and a roller 6 are provided at the bottom end of the walking footrest 3, the driving motor 5 is connected to the roller 6, the controller 4 is connected to the driving motor 5, an elastic component 7 and a power supply 8 are further provided on the side of the walking footrest 3, the generator 2 is connected to the power supply 8, the power supply 8 is respectively connected to the driving motor 5 and the controller 4, and the elastic component 7 is connected to the rotor of the generator 2.

[0050] Refer to Figures 1-4 , a storage board 9 and a rotating motor 10 which are connected to each other are further provided at the bottom end of the walking footrest 3, and the roller 6 and the driving motor 5 are arranged at the bottom of the storage board 9.

[0051] Refer to Figures 1-4 , when not assisting the user to move, the storage board 9 can be arranged at the position of the user's heel. When it is necessary to assist the user to walk, the rotating motor 10 can drive the storage board 9 to rotate, so that the storage board 9 is placed under the user's foot sole or shoe sole to support the user's feet, and then the roller 6 at the bottom of the storage board 9 can directly contact the floor to assist the user to walk.

[0052] In an embodiment, the waistband 1 may be provided with a magic tape and a buckle (similar to a belt buckle) so that the user can strap it around the waist. And a cord can be provided on the inner side of the walking footrest 3 to strap it to the user's legs; optionally, a magic tape can also be provided on the inner side of the walking footrest 3 to stick to the user's pants to prevent the walking footrest 3 from falling off.

[0053] Refer to Figures 1-4, after the user fastens the waistband 1 and the walking footrest 3, the feet directly touch the ground, and then the user walks randomly. During walking, the walking footrest 3 moves with the swinging of the user's legs, causing the elastic component 7 to pull the rotor of the generator 2 to rotate as the walking footrest 3 moves back and forth, thereby enabling the generator 2 to generate electrical energy and charge the power supply 8.

[0054] During walking, the controller 4 can collect environmental images of the current walking path through a camera and collect the power value of the power supply 8 through various sensors. Then, if the controller 4 determines that it is necessary to assist the user in walking based on the environmental image and the power value, it can control the rotating motor 10 to rotate the storage board 9, causing the storage board 9 to gradually rotate forward from its original position placed at the user's heel. During this period, the user can gently stand on tiptoe, allowing the storage board 9 to lift the feet from the user's heel, enabling the user's feet to step on the storage board 9. After the user stands firm, the controller 4 can control the driving motor 5 to start, causing the driving motor 5 to drive the rollers 6 to rotate to assist the user in walking.

[0055] In a specific implementation, going uphill is the most time-consuming and laborious for the user, especially for the elderly. For the scenario of going uphill, the operation steps for the controller to determine that it is necessary to assist the user in walking based on the environmental image and the power value can specifically include the following steps:

[0056] First, extract the path image of the current path from the environmental image;

[0057] Second, generate a walking route of the current path based on the path image fitting;

[0058] Third, extract several feature points from the walking route and calculate the slope between adjacent two feature points to obtain multiple slope values;

[0059] Fourth, sum the multiple slope values on average to obtain the slope value of the current path;

[0060] Fifth, if the slope value is greater than the preset slope value and the power value is greater than the preset power value, then control the driving motor to start.

[0061] Specifically, a coordinate system can be established with the camera as the central origin for reference. Then, the origin of the coordinate system coincides with the optical center of the camera, the Z-axis coincides with the optical axis of the camera, and the direction is forward. The Y-axis is perpendicular to the camera body, and the direction is upward. The X-axis is perpendicular to the camera body, and the direction is to the left. The forward direction of the user is the Z-axis of the coordinate system, vertically upward is the Y-axis, and the X-axis is perpendicular to the plane where these two coordinate axes are located and points to the left.

[0062] Next, the image of the current path can be recognized in the environmental image to obtain the path image, and the path image can be intercepted from the environmental image. Then, the straight line information of the path image can be extracted through probabilistic Hough transform. Of course, in other embodiments, the straight line information can also be extracted by other means to obtain its walking route.

[0063] Optionally, the walking route of the road surface can also be fitted by adding constraint conditions. Specifically, fitting the walking route of the road surface by adding constraint conditions may include the following steps:

[0064] First, according to the rule that when the camera is imaging, the walking route can be located below the environmental image and extend upward from the bottom end of the environmental image and converge at a point at infinity, the walking route can be fitted by adding constraint conditions. Among them, the constraint conditions can be the width constraint condition and length constraint condition of the walking route, etc.

[0065] After the walking route has been detected, the change in the slope of the walking route can be analyzed. The analysis method may include the following steps: first, extract several (denoted as N, N is a positive integer) feature points on the walking route, calculate the slope of the straight line where two adjacent feature points are located. Through the slope, the slope change of the section of the road divided by two adjacent feature points can be determined. If the slope between two feature points is positive, it means that this section of the road is uphill. On the contrary, if the slope between two feature points is negative, it means that this section of the road is downhill.

[0066] During actual walking, the road may be a mixture of uphill and downhill, and the overall change of the road may not be significant and does not require assisting the user to walk. If the road is continuously uphill and the user walks with difficulty, assistance is needed for the user to walk. For this reason, multiple slope values can be added and then averaged to obtain the slope of the entire section of the road, so that the slope of this section of the road can be determined according to the slope of the entire section of the road.

[0067] Finally, when the slope value is greater than the preset slope value and the power value is greater than the preset power value, it means that this walker can assist the user to walk, and the driving motor 5 can be controlled to start. Specifically, the user first stands on tiptoe to let the storage board 9 support the user, and then the driving motor 5 controls the roller 6 to rotate to assist the user to walk.

[0068] It should be noted that the user can adjust the length constraint condition according to their actual needs. For example, 50 meters, 100 meters, 200 meters, etc. For example, if the user is an elderly person, within 50 meters, when the slope value is greater than the preset slope value and the power value is greater than the preset power value, it can be started to assist the elderly to move. If the user is a middle-aged person, the length constraint condition can be 100 meters. If the user is a young person, the length constraint condition can be 200 meters, etc.

[0069] The monocular vision-based road surface slope calculation method in this embodiment first extracts the straight line information from the collected road surface image information, fits the lane lines of the road surface, then extracts feature points on both sides of the lane lines, and further calculates the slope between the two feature points, so as to be able to grasp the slope change of the lane lines in real time, and further judge the slope change of the road surface ahead. Finally, the coordinates of the road surface vanishing point are calculated, and the slopes of each sloped road surface are calculated using the coordinate information, thereby realizing the calculation of the road surface slope using monocular vision, which can better analyze the position information of obstacles, improve the accuracy of obstacle distance measurement, and ensure the life and health of drivers.

[0070] Optionally, the controller 4 can also be provided with a number of physical buttons, and the physical buttons are displayed on the side of the waistband 1. The human intelligent walker can be started or stopped by pressing the physical buttons, which is convenient for users to operate.

[0071] In order not to affect the daily movement of users, referring to Figures 1-4 , in one embodiment, the walking leg frame 3 is divided into a thigh leg frame 31 and a calf leg frame 32. One end of the thigh leg frame 31 is movably connected to one end of the calf leg frame 32. The thigh leg frame 31 is provided with a thigh positioning frame 33, and the calf leg frame 32 is provided with a calf positioning frame 34;

[0072] The elastic component 7 includes a compression rod 71, a movable block 72 and a spring 73 connected in sequence. The other end of the compression rod 71 is connected to the thigh positioning frame 33, and the other end of the spring 73 is connected to the calf leg frame 32. The compression rod 71 pushes the movable block 72 to move back and forth when the user walks.

[0073] Specifically, a connecting head can be provided between the thigh leg frame 31 and the calf leg frame 32, which allows the thigh leg frame 31 and the calf leg frame 32 to swing freely relative to each other. The structure of the connecting head is similar to the connecting end of scissors.

[0074] One end of the compression rod 71 can also be movably connected to the thigh positioning frame 33. When the user is not walking, the compression rod 71, the movable block 72 and the spring 73 are all stationary; when the user walks, the user lifts the thigh, causing the thigh leg frame 31 and the calf leg frame 32 to fit and approach each other, so that the thigh positioning frame 33 drives the compression rod 71 to swing and compress the movable block 72, causing the movable block 72 to compress the spring 73 downward. When the user lowers the thigh, the thigh leg frame 31 and the calf leg frame 32 separate from each other to form an upright state, and at the same time the spring 73 can bounce the movable block 72 upward to make it return to its original position. During the user's movement, the movable block 72 can move up and down continuously.

[0075] Referring to Figures 5-6 , respectively show the structural schematic diagram of the elastic component pulling the generator to rotate provided by an embodiment of the present inventionFigure 1 Schematic diagram of the structure where the elastic component provided by an embodiment of the present invention pulls the generator to rotate Figure 2 .

[0076] In one embodiment, the generator 2 is provided with a rotating plate 21, the rotor of the generator 2 is arranged in the rotating plate 21, the movable block 72 is provided with a connecting rope 74, and the connecting rope 74 is connected to the rotating plate 21.

[0077] Combined with the above description of the user's walking, the movable block 72 can move up and down during the user's walking. During the movement of the movable block 72, the movable block 72 can pull the rotating plate 21 to rotate in a single direction through the connecting rope 74, and then the rotating plate 21 can drive the rotor to rotate, so that the generator 2 generates electric energy.

[0078] Refer to Figures 5-6 , the arrow direction on the rotating plate 21 is the rotating direction of the rotating plate 21.

[0079] In practical applications, when the user keeps walking, the rotor will keep rotating, so that the generator 2 can generate a stable current to charge the power supply 8.

[0080] It should be noted that the generator 2 can be directly connected to the power supply 8, and when current is generated, it can directly charge the power supply 8. Specifically, the generator 2 can be provided with wires for charging and is directly connected to the power supply 8 through the wires.

[0081] In order to match the power supply 8, the user can set the number of turns and turns ratio of the coil of the generator 2 according to their actual needs, or a corresponding power matching circuit can be set at the input end of the power supply 8, so that the current generated by the generator 2 can match the charging current of the power supply 8 to meet the charging requirements of the power supply 8, and it can be specifically adjusted according to actual needs.

[0082] Optionally, each device such as the thigh leg frame 31, the calf leg frame 32, the thigh positioning frame 33, the calf positioning frame 34, etc. can be made of materials such as technology and hard plastic.

[0083] In this embodiment, the embodiment of the present invention provides a human body intelligent walker, and its beneficial effects are as follows: The present invention provides a walking leg frame that can be tied to the user's legs, and an elastic component that can move back and forth is arranged in the walking leg frame. The elastic component drives the generator to rotate back and forth to generate electric energy, and then uses the electric energy to charge the power supply, so as to improve the endurance of the entire walker and improve the utilization rate of resources.

[0084] During the application process, the situation of insufficient battery power may occur. In order to prompt the user to charge in real time and avoid the interruption of walking, the following will introduce and illustrate in detail a charging prompt method for a human body intelligent walker provided by an embodiment of the present application through specific embodiments below.

[0085] Referring to Figure 7 , a flowchart showing a charging prompt method for a human body intelligent walker provided by an embodiment of the present invention is shown.

[0086] In this embodiment, the method may be applicable to the human body intelligent walker of the above embodiment.

[0087] Among them, by way of example, the charging prompt method for the human body intelligent walker may include:

[0088] S11. When the human body intelligent walker assists the user to walk, the current battery power value of the human body intelligent walker is collected in real time.

[0089] In this embodiment, when the human body intelligent walker starts and assists the user to walk, the current battery power value of the power supply of the human body intelligent walker may be collected in real time.

[0090] S12. If the current battery power value is less than the preset battery power value, a charging voice is generated and played to prompt the user to charge the human body intelligent walker.

[0091] If the current battery power value is less than the preset battery power value, it means that the battery power of the power supply is too low to continue assisting the user to drive. In order to avoid the situation that the user may fall or walk unsteadily due to sudden power off, a charging prompt voice can be immediately generated and played to prompt the user to charge the human body intelligent walker.

[0092] In an embodiment, the human body intelligent walker is provided with a controller, and the controller can be connected to the user's mobile terminal, or the controller can send the prompted charging voice to the mobile terminal, and the mobile terminal plays the voice to prompt the user to perform the charging operation.

[0093] Since the human body intelligent walker can be charged not only through an external power supply but also through the user's walking movement, the charging voice can be generated by combining the content of the two charging methods. In an optional embodiment, step S12 may include the following sub-steps:

[0094] S121. Obtain the minimum swing frequency value of the walking footrest of the human body intelligent walker, and generate and play a charging voice according to the minimum swing frequency value.

[0095] Specifically, the minimum swing frequency value is the frequency value required for the rotating plate 21 to rotate when the generator can generate a current sufficient to charge the power supply. Since the rotating plate 21 rotates by the up and down movement of the movable block 72, and the frequency of the up and down movement of the movable block 72 is based on the user's walking frequency, the minimum swing frequency value can be calculated by calculating the frequency value required for the rotating plate 21 to rotate. For example, it swings once every 0.8 seconds, once every 1 second, and so on. Based on this minimum swing frequency value, a piece of voice is generated and then played to prompt the user to control the human intelligent walker to stop and start walking by himself to charge the human intelligent walker for the next assisted walking.

[0096] Or;

[0097] S122. Obtain the current coordinates of the user, search for several charging station information based on the current coordinates, and generate and play a charging voice based on the several charging station information.

[0098] Specifically, the charging station information can be the address information of various vehicle terminals. The address information of several charging stations is made into a voice and played to the user for the user to go to the corresponding address and use the plugs of each charging station to charge the power supply.

[0099] In this embodiment, the present invention provides a charging prompt method for a human intelligent walker, and its beneficial effect is that: when the power of the human intelligent walker is insufficient, the present invention can timely generate and play a corresponding charging prompt voice to prompt the user to charge in time, thereby avoiding the situation that the user walks unsteadily or falls due to power failure during the assisted walking process.

[0100] The embodiment of the present invention also provides a charging prompt device for a human intelligent walker. Refer to Figure 8 , which shows a schematic structural diagram of a charging prompt device for a human intelligent walker provided by an embodiment of the present invention.

[0101] Among them, by way of example, the charging prompt device for the human intelligent walker may include:

[0102] A collection module 801, which collects the current power value of the human intelligent walker in real time when the human intelligent walker assists the user to walk;

[0103] A prompt module 802, which is used to generate and play a charging voice to prompt the user to charge the human intelligent walker if the current power value is less than a preset power value.

[0104] Optionally, the prompt module is further used for:

[0105] Obtain the minimum swing frequency value of the walking footrest of the human body intelligent walker, and generate and play a charging voice according to the minimum swing frequency value;

[0106] Or;

[0107] Obtain the current coordinates of the user, search for several charging station information based on the current coordinates, and generate and play a charging voice based on the several charging station information.

[0108] Those skilled in the art can clearly understand that for the convenience of description and simplicity, the specific working process of the above-described device can refer to the corresponding process in the foregoing method embodiment, and will not be repeated here.

[0109] Furthermore, an embodiment of the present application further provides an electronic device, including: a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the program, it implements the charging prompt method of the human body intelligent walker as described in the above embodiment.

[0111] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
