[0001] The invention relates to the technical field of infant learning to walk assistance, and in particular to an interactive infant learning to walk toy based on intelligent guidance. Background Art

[0002] Toddler toys (walkers) are tools for babies to learn to walk. They are tools for babies to walk before they learn to walk and for assisting them in walking. Traditional toddler toys (walkers) have relatively simple functions and only have the function of learning to walk. When there are obstacles nearby and they come into contact with them, the toddler toys (walkers) often fall over due to the continuous pressure exerted by the infants, which affects the health of the infants. It is impossible to provide timely feedback to remind the real-time guardians and protect the health of the infants, which makes the existing toddler toys (walkers) less intelligent and less functional.

[0039] The control panel 103 includes a data storage unit, a basic operation unit, a deep processing unit and an early warning execution unit.

[0040] The specific working process and principle of the present invention are as follows:

[0041] Step 1: Spread the legs of the infant and pass them through the split-leg connecting pad 8. At this time, the infant's crotch applies a downward pulling force to the split-leg connecting pad 8. After the split-leg connecting pad 8 moves downward, it drives the two anti-skid pressure-sensing pads 7 fixed thereto to stretch downward. After the anti-skid pressure-sensing pads 7 stretch downward, their reverse force acts on the infant's crotch and lower waist, making the infant's walking more stable. At the same time, after the anti-skid pressure-sensing pad 7 stretches downward, it drives the locking piece locked with it to move relative to it through the locking protrusion 701. After the locking piece moves relative to it, it drives The fixed limit slide bar 911 slides out from the sensing cylinder 901. After the limit slide bar 911 slides out from the sensing cylinder 901, it drives the limit sensing slider 908 fixed thereto to slide along the inner wall of the sensing cylinder 901 and squeeze the limit sensing elastic ring 909 to make it shrink. After the limit sensing elastic ring 909 shrinks, its reverse force acts on the surface of the second pressure sensor 910, so that the second pressure sensor 910 senses the pressure, thereby generating the infant positioning pressure value and sending it to the data storage unit for storage;

[0042] Step 2: The basic operation unit obtains the infant positioning pressure value and the preset pressure value of the data storage unit in real time, compares the infant positioning pressure value with the preset pressure value, and generates a guidance start signal when the infant positioning pressure value is less than the preset pressure value, otherwise, no guidance start signal is generated;

[0043] When the guidance start signal is generated, the guidance component 3 is started to operate to guide the direction of the infant learning to walk;

[0044] The duration of the guidance start signal is sensed and compared with the preset learning time. When the duration of the guidance start signal reaches the preset learning time, the operation of the component is automatically turned off, and the learning time text is edited, and the learning time text is sent to the warning speaker 104 for playing;

[0045] The text of the learning time is "The learning time of the toddler has reached the limit. Please pick up the toddler and let him learn by himself." When the toddler leaves the toddler, the electrical components of the toddler will be automatically turned off;

[0046] Through the guidance of learning toys and self-study, the memory of infants and young children can be strengthened, and the efficiency of learning to walk can be improved; in order to prevent the problem of hip dysplasia and the formation of figure eight gait caused by the soft hip joints of infants and young children and the long-term learning to walk with legs apart;

[0047] Step three, after the guide assembly 3 is started to guide the infant to learn to walk, the first pressure sensor 907, the second pressure sensor 910 and the ultrasonic sensor 2 are started synchronously; after the ultrasonic sensor 2 is started, it senses the shortest straight-line distance between the obstacle and the outer end surface of the annular shell 1 in real time and sends it to the data storage unit. At the same time, as the infant walks under the guidance of the guide assembly 3, the toddler toy is pushed to move. When the annular pressure-sensing bag 6 abuts against the obstacle, the annular pressure-sensing bag 6 will shrink and deform. After the annular pressure-sensing bag 6 shrinks and deforms, the gas inside the annular pressure-sensing bag 6 enters the induction cylinder 901 through the gas flow pipe 904 and the air holes opened in the induction cylinder 901. The induction cylinder 901 The air pressure gradually increases, indicating that the infant has a tendency and intention to continue moving toward the obstacle. At this time, the gas from the contraction of the annular pressure-sensing bag 6 enters the sensing cylinder 901, pushes the air pressure-sensing slider 905 to slide along the inner wall of the sensing cylinder 901 and squeezes the air pressure-sensing spring pad 906 abutting against it. The air pressure-sensing spring pad 906 contracts after being squeezed and squeezes the first pressure sensor 907. At this time, the first pressure sensor 907 senses the reverse pressure value of the air pressure-sensing spring pad 906, thereby generating the instantaneous pressure increase rate of the annular pressure-sensing bag 6 when it contacts the obstacle. The first pressure sensor 907 also sends the generated instantaneous pressure increase rate of the annular pressure-sensing bag 6 when it contacts the obstacle to the data storage unit.

[0048] Step 4: The deep processing unit obtains the shortest straight-line distance between the obstacle and the outer end surface of the annular shell 1 and the instantaneous pressure increase rate of the annular pressure-sensing bag 6 when it contacts the obstacle through the data storage unit, and then calibrates JX and JV. According to the formula A=(k1*JX+k2*JV) / 2, the toddler toy trajectory warning factor A is obtained, and the toddler toy trajectory warning factor A is compared with the preset warning value a. When the toddler toy trajectory warning factor A is not greater than the preset warning value a, no control signal is generated. When the toddler toy trajectory warning factor A is greater than the preset warning value a, a trajectory warning signal is generated, and the trajectory warning signal is sent to the warning execution unit; the trajectory warning signal is used to determine whether the toddler toy needs to be automatically or manually controlled to prevent the toddler toy from tipping over; k1 and k2 are both simulation weight parameters, and the simulation weight parameters make the calculation result closer to reality;

[0049] Step 5, after receiving the trajectory warning signal, the warning execution unit records and edits the warning reminder text and sends it to the warning speaker 104 for playback; the warning reminder text is "the toddler toy is about to fall over, please adjust the position of the toddler toy in time"; and in this process, it is necessary to first input the infant's characteristic information, which includes the infant's age, gender, height, weight, etc., so as to match the best preset warning value, because age, height, weight and gender will affect the thrust of the infant, and the thrust range is different, resulting in a corresponding change in the preset warning value, so that the toddler toy warning is more accurate;

[0050] In summary of the above technical solutions, the present invention is based on the operation of the automatic control guidance component 3 of the infant in-position sensing to attract the attention of the infant and guide it to move and learn to walk, and collects the time when the infant learns to walk at the learning toddler toy, prevents the infant from excessively learning at the learning toddler toy, realizes the guidance and autonomous mode of the learning toddler toy, strengthens the learning toddler memory of the infant and young child, assists in improving the learning toddler efficiency of the infant and young child, and realizes the automatic closing function when the infant and young child leave the position, saving energy. At the same time, in this process, by collecting parameter information between the learning toddler toy and the obstacle, the force direction and movement trend of the infant and young child are judged, and the early warning reminder function of the collision and dumping of the learning toddler toy and the obstacle is realized, which assists the real-time guardian to take care of the infant and young child and ensures the safety of the infant and young child. Therefore, the intelligence of the present invention is significantly increased, and the functions are more comprehensive and diverse, which solves the problem that the traditional learning toddler toy (learning toddler walker) has a relatively single function and only has the function of infant learning to walk. When there is an obstacle nearby and it touches it, it cannot timely feedback to remind the real-time guardian, causing the learning toddler to dump, and the intelligence is poor, which affects the physical health of the infant and young child.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
