the elastic clamping plate 3a is clamped on the rear push rod 1c of the baby carriage body, and the electric control box body 3b can be fixed on the rear push rod 1c of the baby carriage body by using a binding belt or a binding band in cooperation with the elastic clamping plate 3 a;

the elastic buckles 5b are clamped on the baby carriage body and matched with the ribbon or the bandage, so that the collision avoidance mechanisms 5 can be quickly arranged on the front side, the left side and the right side of the baby carriage body;

the power switch 3g is pressed, the device enters a starting state, if any button is not pressed, the mainboard is controlled to enter a strolling mode, if the mode needs to be adjusted, the mode button 3d is pressed for a long time, at the moment, the device enters an adjustment mode state, after the adjustment mode state is entered, the device still enters the strolling mode without pressing the button within two seconds, the device presses once, enters an indoor playing mode, presses twice, enters an outgoing straight-going trolley mode, and the direct-current lithium battery provides electric energy for driving the motor 2g to pass through;

the walking baby mode is as follows: the control main board sends a signal to the motor driving module, the motor driving module controls the two driving motors 2g to intermittently switch forward and reverse, so that the driving wheel 2b is controlled to intermittently move forward and backward at a slow speed, namely the driving motors 2g rotate forward for a plurality of seconds and keep moving straight, the driving motors 2g rotate backward for the same time and keep moving backward at equal intervals, and then the motor enters into circulation work, and other electric elements do not work;

indoor play mode: the control mainboard sends a signal to the motor drive module, the motor drive module controls two drive motors 2g to work simultaneously, so as to control the drive wheel 2b to go forward linearly indoors, the magnetometer and the gyroscope detect the current direction of the baby carriage, the direction of the baby carriage is controlled, when the collision avoidance mechanism 5 senses that a front obstacle exists, the collision avoidance mechanism 5 transmits the signal to the control mainboard, the control mainboard sends the signal to the motor drive module, the motor drive module controls the two drive motors 2g to rotate in a differential mode, and the rotating speed of the left drive motor 2g is smaller than that of the right drive motor 2g, namely the left drive motor turns 90 degrees; similarly, when the front and the left meet the obstacle, the vehicle turns 90 degrees to the right; when the front and the right meet the obstacle, the vehicle turns 90 degrees to the left; when the front, the left and the right of the vehicle meet an obstacle or the upper part of the vehicle meets an obstacle, the motor driving module controls the two driving motors 2g to rotate in a differential mode, and the vehicle turns around for 180 degrees to avoid collision or enter the bottom of an object;

going out and going straight to the trolley mode: the control mainboard sends a signal to the motor drive module, the motor drive module controls two driving motors 2g to keep the theoretical rotational speed unanimous, realize advancing at low speed, meet the barrier in the response place ahead of collision avoidance mechanism 5, control driving motor 2g stop work immediately, if no matter the road is uneven road or stone reason, the stroke of two driving motors 2g is different, lead to the direction transformation, magnetometer and the current direction that the perambulator was located of gyroscope detection, all can keep the direction of previous record, control and revise the direction of perambulator.

Interconnection with external mobile devices: according to power switch 3g, this device gets into the power-on state, and bluetooth module starts this moment, uses outside mobile device to connect bluetooth module like cell-phone APP, realizes the interconnection of this device and cell-phone, can remote control switch after connecting and walk child mode, indoor recreation mode, go out and go straight dolly mode and manual mode of controlling, functions such as steerable shutdown and demonstration direct current lithium cell electric quantity simultaneously.

Manual operation mode: can only select to get into the manual mode of controlling through outside mobile device, get into the back, APP gets into the manual mode interface of controlling, interface inside all around, pause, shutdown, virtual keys such as return are controlled, cell-phone APP passes through wireless bluetooth transmission with control information to bluetooth module, bluetooth module transmits control information to the control mainboard, control mainboard send signal to motor drive module, two driving motor 2g work of motor drive module control, thereby control perambulator advance retreat and control to turn to, steerable pause simultaneously, shutdown and return last interface.

In conclusion, the two driving mechanisms 2, the electric control box 3 and the collision avoidance mechanism 5 can be quickly and simply installed on the baby carriages with different shapes and sizes, the application range is wide, differential motion of the driving wheel 2b is realized through the driving motor 2g, the control main board and the motor driving module, the functions of the baby carriage such as advancing, retreating and steering in a small space are met, the baby carriage has different intelligent baby walking modes, hands of a guardian are liberated, the baby carriage is suitable for indoor and outdoor use, and the application range is wide; the current direction of the baby carriage is detected and corrected through the cooperation of the gyroscope and the magnetometer, the control is convenient, and the safety performance is high; through bluetooth module and outside mobile device connection, realize the switching of the mode of strolling baby and get into the manual mode of controlling, but remote control perambulator action.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
