A front right wheel (not shown in the figure) and a front left wheel 122 are provided at the bottom of the front wheel bracket 12. A rear right wheel 131 and a rear left wheel 132 are provided at the bottom of the rear wheel bracket 13. The rear end of the body bracket 11 is connected to the armrest 15. The seat 14 is installed on the body bracket 11. The guardrail 16 is provided at the front end of the seat 14. The canopy 17 is provided at the upper end of the seat 14. Secondly, the main control module 20 is provided on a base 151 of the armrest 15 of the trolley 10. The main control module 20 includes a controller 21, a brake controller 22, a first wireless communication module 23 and a satellite positioning system 24. The controller 21 is electrically connected to the brake controller 22, the first wireless communication module 23 and the satellite positioning system 24. The brake controller 22 is used to control at least one drive motor 34 and at least one brake gear 221 of the trolley 10. Among them, the at least one drive motor 34 includes a rear right wheel motor 341 and a rear left wheel motor 342. The rear right wheel motor 341 is arranged in a right hub of the rear right wheel 131. The rear left wheel motor 342 is arranged in a left hub of the rear left wheel 132. The first wireless communication module 23 is communicatively connected to a portable electronic device 231 in a wireless manner. Among them, the wireless manner is one of a Bluetooth communication protocol, a wireless network protocol, a wireless RF communication, a broadband network communication, Zigbee, Thread, a 3G communication protocol or a 4G communication protocol. And the satellite positioning system 24 can send a position information to the portable electronic device 231 via the first wireless communication module 23 to confirm the position of the trolley 10.

[0016] As Figure 2 and Figure 3As shown, the power control module 30 is disposed at the bottom of the rear wheel bracket 13. The power control module 30 includes a second wireless communication module 31, a power supply module 32, a foot brake member 33, a rear right wheel motor 341 and a rear left wheel motor 342, two reduction mechanisms 35, two drive controllers 36 and a motor drive board 37. The power supply module 32 is electrically connected to the second wireless communication module 31 and the main control module 20 (it should be emphasized here that the main control module 20 can also be provided with an independent power supply module to provide independent power to the main control module 20). Through the second wireless communication module 31, the power control module 30 is wirelessly communicatively connected to the main control module 20 and the portable electronic device 231. Among them, the foot brake member 33 is disposed between the rear right wheel 131 and the rear left wheel 132. The rear right wheel motor 341 and the rear left wheel motor 342 can output rotational speed and output torque. The two reduction mechanisms 35 are respectively connected to the rear right wheel motor 341 and the rear left wheel motor 342, and the output rotational speed and output torque of the rear right wheel motor 341 and the rear left wheel motor 342 are changed through the two reduction mechanisms 35. The two drive controllers 36 are connected to the rear right wheel motor 341 and the rear left wheel motor 342, and the rear right wheel motor 341 is connected to the motor drive board 37 through a motor right signal line 3411, and the rear left wheel motor 342 is connected to the motor drive board 37 through a motor left signal line 3412. The two brake gears 221 are respectively fixed inside the tires of the rear right wheel 131 and the rear left wheel 132 and rotate at the same speed as the tires. The circumferential side of each brake gear 221 has a plurality of teeth. The foot brake member 33 is swingable downward and has a latch rod on each side. When the foot brake member 33 is stepped on for braking, the latch rod latches on the teeth, forcing the rear right wheel 131 and the rear left wheel 132 to stop rotating. Furthermore, the intelligent trolley 1 further includes an inclination sensor 40 and a pressure sensor 41. The inclination sensor 40 is installed inside the rear right wheel 131 and the rear left wheel 132. The inclination sensor 40 is used to detect an inclination 401 of the trolley 10 and send the sensed inclination 401 to the controller 21. In the case where the trolley 10 is not braked through the foot brake member 33, the controller 21 determines whether to send a brake signal to the brake controller 22 according to the inclination 401 to stop the trolley 10. Also, the inclination sensor 40 sends the sensed inclination 401 to the controller 21, and when the controller 21 determines that the inclination 401 is an uphill inclination, the drive motor 34 is caused to increase current through the power control module 30, thereby increasing the force for the trolley 10 to go uphill.Secondly, the pressure sensor 41 is disposed on the seat 14. By detecting a weight, it transmits a pressure sensing signal 411 and sends the pressure sensing signal 411 to the controller 21. When the controller 21 does not receive the pressure sensing signal 411 from the pressure sensor 41 at all, it transmits a warning instruction 440 to a warning unit 44 to generate a warning signal 443. Among them, the warning unit 44 is a vibrator 441 or a buzzer 442 disposed on the stroller 10, and the warning signal 443 is vibration or an alarm sound. In addition, the main control module 20 further includes a voice playback unit 25. The voice playback unit 25 transmits a voice signal to the controller 21, and the controller 21 transmits the voice signal to the buzzer 442 through the first wireless communication module 23 and plays it through the buzzer 442. Among them, the voice signal includes music or a story.

[0017] Such as Figure 2 And Figure 4As shown, a holding part 152 of a touch sensor 1521 is provided on the main control module 20. The controller 21 is electrically connected to the touch sensor 1521. When the hand of a pusher touches a holding part 152, the touch sensor 1521 emits an induction signal 1522 to the controller 21, and the controller 21 commands the brake controller 22 to release the locking of the two brake gears 221 on the rear right wheel 131 and the rear left wheel 132. When the hand of the pusher leaves the holding part 152, the touch sensor 1521 does not release any induction signal 1522, and the controller 21 commands the brake controller 22 to start locking the rear right wheel 131 and the rear left wheel 132. Secondly, the main control module 20 on the armrest 15 includes two start keys 1511, a left turn key 1512, a right turn key 1513 and a control module 1514. The setting positions of the two start keys 1511, the left turn key 1512 and the right turn key 1513 can be arbitrarily changed according to the needs of the user. The two start keys 1511 can be set at the front end of the main control module 20, and the left turn key 1512 and the right turn key 1513 can be set on the opposite sides of the two start keys 1511, but the present invention is not limited thereto. The control module 1514 is arranged above the main control module 20. The main control module 20 is embedded with a circuit board (not shown in the figure), and the circuit board is electrically connected to the drive controller 36 and the power module 32. Wherein, each start key 1511 is provided with a fingerprint recognition unit 42 for extracting a fingerprint information 421, and the controller 21 judges whether the fingerprint information 421 is consistent with the fingerprint information input for the first time. If they are consistent, a brake release instruction is generated. Secondly, the control module 1514 has a power key 15141, an acceleration key 15142, a deceleration key 15143 and a reverse key 15144. The left turn key 1512, the right turn key 1513, the acceleration key 15142, the deceleration key 15143 and the reverse key 15144 can control the rotation direction of the drive motor 34 to drive the trolley 10 to move forward, backward or turn. The control module 1514 is a touch screen or a display screen.

[0018] As Figure 2 and Figure 5 shown, the intelligent trolley 1 further includes a camera 43. The camera 43 is arranged on the guardrail 16 of the trolley 10. The camera 43 is a fish-eye camera and can be communicatively connected to the controller 21. The camera 43 is used for extracting a plurality of images 431 around the trolley 10 and wirelessly transmitting the plurality of images 431 to the portable electronic device 231 to monitor the environmental conditions of the trolley 10.
