Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

Examples

As shown in figure 1, the self-homing slippers provided by the invention comprise soles 1 and vamps 2, wherein the soles 1 are made of hard plastics or wood, driving wheels 3 are arranged at the tail parts of the soles 1 along the front side and the rear side in the figure, and steering wheels 4 are arranged at the front ends of the soles 1.

As shown in fig. 2 and fig. 3, the driving shaft 8 connecting the two driving wheels 3 transversely penetrates through the sole 1, the driving shaft 8 is relatively rotatably disposed in the sole 1, and both the two driving wheels 3 are fixedly connected with the driving shaft 8. The inside at sole 1 is equipped with the cavity, installs initiative motor 5 in the cavity, and fixedly connected with first initiative umbrella tooth 6 in the pivot of initiative motor 5 is fixed with the second initiative umbrella tooth 7 with first initiative umbrella tooth 6 meshing on the perisporium of initiative pivot 8, and initiative motor 5 passes through first initiative umbrella tooth 6 and drives first initiative umbrella tooth 6 and rotate, and first initiative umbrella tooth 6 rotates the back and provides power for action wheel 3 rotates.

As shown in figure 4, a steering shaft 12 is arranged between the steering wheel 4 and the sole 1, the steering shaft 12 is approximately L-shaped, and the steering shaft 12 is arranged in the sole 1 in a manner of relatively rotating along the vertical direction. The steering wheel 4 is arranged on the end of the steering shaft 12 in a relatively rotatable manner. And the top position of a steering shaft 12 is provided with a second steering umbrella tooth 11, a cavity in the sole 1 is provided with a steering motor 9, a rotating shaft of the steering motor 9 is fixedly connected with a first steering umbrella tooth 10, and the first steering umbrella tooth 10 is meshed with the second steering umbrella tooth 11.

The steering motor 9 drives the second steering bevel gear 11 to rotate through the first steering bevel gear 10, the steering shaft 12 rotates along the axis (vertical direction) of the vertical part after the second steering bevel gear rotates, so that the steering shaft 12 drives the steering wheel 4 to pivot, and a rotating groove for pivoting the steering wheel 4 is dug in the sole 1. The steering wheel 4 rotates along with the rotating shaft, so that the direction of the steering wheel 4 can be adjusted, and the whole sole 1 can steer under the thrust of the driving wheel 3. Meanwhile, the steering wheel 4 can also rotate along the transverse part of the steering shaft 12, and when the driving wheel 3 rotates, the steering wheel 4 rotates along the steering shaft 12, so that the rolling advance of the steering wheel 4 is not influenced.

The height of the bottommost side of the driving wheel 3 and the steering wheel 4 is approximately the same as that of the sole 1, most of the area of the sole 1 is pressed on the ground, and therefore the situation that a person steps on the sole 1 and slips and falls because only the driving wheel 3 and the steering wheel 4 contact the ground does not occur.

The driving motor 5, the steering motor 9, the first driving bevel gear 6, the second driving bevel gear 7, the driving rotating shaft 8, the first steering bevel gear 10 and the second steering bevel gear 11 are used as walking mechanisms and used for automatically returning to the original position when a user does not use the slippers.

As shown in fig. 5, a first pressure sensor 13 and a second pressure sensor 14 are respectively disposed on the top surface of the sole 1 and the bottom surface of the sole 1, the first pressure sensor 13 is used for detecting whether a user uses the slipper, when the user uses the slipper, the first pressure sensor 13 receives a pressure signal due to the pressure of the user, and similarly, the second pressure sensor 14 also receives a pressure signal generated by the weight of the user. The second pressure sensor 14 and the first pressure sensor are used together for detecting whether the sole 1 is turned over. If the sole 1 is turned upside down, the user does not use the slipper naturally, and the second pressure sensor 14 cannot receive the pressure signal at this time, while the first pressure sensor 13 receives the pressure generated from the weight of the sole 1.

The invention is also provided with two bionic wave generators, and the sole 1 is provided with an ultrasonic receiver. The two bionic wave generators continuously send ultrasonic waves, the distance between the slippers and the bionic wave generators is determined by the included angle of the two ultrasonic waves, and the ultrasonic receiver continuously approaches the bionic wave generators after receiving the homing signals sent by the bionic wave generators.

The ultrasonic sensor also comprises a control module, wherein the control module processes signals of the first pressure sensor 13, the second pressure sensor 14 and the ultrasonic receiver, the control module is arranged in the cavity, and the model of a chip of the control module is AT89C 51.

The first pressure sensor 13 and the second pressure sensor 14 can adopt an AP8012 pressure sensor; the ultrasonic receiver can adopt an ultrasonic receiver of AVM58N-K1 ROBN;

the first pressure sensor 13 is connected with the negative input end of the logic controller through the switch circuit and the analog-to-digital converter in sequence, and the ultrasonic receiver is connected with the positive input end of the logic controller through the analog-to-digital converter. The first pressure sensor 13 and the ultrasonic receiver are calculated and output by a logic controller, and the logic controller adopts a NAND gate. The analog-to-digital converter adopts an analog-to-digital converter of ADC 0809.

The ultrasonic receiver inputs a high level, when the self-homing slippers are not used, the first pressure sensor 13 is not stepped by a user, and the switch circuit connected to the tail end of the first pressure sensor 13 outputs the high level. The high level of the ultrasonic receiver and the high level of the first pressure sensor 13 output low level through the nand gate.

The second pressure sensor 14 generates a low level due to no stepping by a user, the second pressure sensor 14 is firstly changed into a high level through non-operation, the high level of the second pressure sensor and the low level output by the NAND gate are output to a high level through the logic operation of another NAND gate, and the high level and the low level are input to the control chip to control the P3.0 port of the first control chip.

After the P3.0 port of the first control chip obtains high level, the first control chip passes through the P3.1 port and the P2.0 port of the second control chip obtains high level, the P2.1 port of the second control chip starts to control the driving motor to rotate under the control high level signal of the P2.0 port of the second control chip, and the driving motor drives the sole to move along the position of the ultrasonic generator.

The P2.0 port of the first control chip receives low level due to the fact that the second pressure sensor receives low level, so that the P2.1 port of the first control chip generates low level, and the low level of the first control chip cannot control the operation of a subsequent circuit.

As shown in fig. 5, the second control chip is electrically connected to the active motor 5 and the steering motor 9. The steering motor is connected to the P3.1 interface of the second control chip. The P3.0 port of the second control chip is connected with a plurality of infrared sensors, and the plurality of infrared sensors are in a logic parallel relation. When any one of the infrared sensor 1, the infrared sensor 2 and the infrared sensor 3 is at a high level, the P3.0 port of the second control chip is at a high level. The distance between the slippers and the external obstacles is detected, so that the working positions of the slippers can be changed in time. A plurality of infrared sensors are installed at the outer side of the shoe sole 1.

When the P3.0 port of the second control chip receives the high-level voltage, the P3.1 port of the second control chip outputs the high level to control the steering motor to rotate. The sole 1 can turn during movement.

The port of the first control chip P2.1 is connected with a buzzer 15. The second pressure sensor 14 generates high level due to the covering, and after the P2.0 high level of the first control chip, the P2.1 port of the first control chip is high level, and at this time, the buzzer 15 makes a sound.
