[0010] The working principle of the present invention is as follows:

[0011] The motor controller is started to start the first motor (6), the second motor (18), the third motor (47), the fourth motor (30), the fifth motor (11), the sixth motor (45), and the seventh motor (37) at the same time. The first motor (6) drives the first gear shaft (16) and the second gear shaft (53) through the gear belt (8) of the gear (7). The first gear shaft (16) and the second gear shaft (53) are driven to engage with the second gear (15) and the fourth gear (54) with the first rack (57) provided on the first guide rod (3) and the second rack (5) provided on the second guide rod (4) to push the first guide rod (3) and the second guide rod (4) out of the main housing (2). At the same time, the second motor (18) The third motor (47) is driven by the third gear (17) and the fifth gear (46) to mesh with the first rack (57) provided on the first guide rod (3) and the second rack (5) provided on the second guide rod (4) to push the first guide rod (3) and the second guide rod (4) out of the main housing (2). At the same time, the fourth motor (30) drives the sixth gear (31) to mesh with the third rack (26) provided on the housing (25) to drive the fourth motor (30) to drive the motor fixing plate (29) to push the plurality of push blocks (27) out of the housing (25). At the same time, the first belt discharger (10) and the second belt discharger (32) are driven by the fifth motor (11) and the seventh motor (37) to mesh with the gears to drive the first belt discharge shaft (9), the third belt discharger (32) and the sixth gear (31) to mesh with the third rack (26) provided on the housing (25). The first and second belt-out shafts (12), the third and fourth belt-out shafts (34 and 35) are connected to the first belt-out shaft (10), the third and fourth belt-out shafts (34 and 35), and the sixth motor (45) drives the torsion spring fixer (44) to drive the steel cable winder (42) through the torsion spring (43) to wind and tighten the first steel cable (14) and the second steel cable (38). The first and second steel cables (14 and 38) drive the first and fourth belt-out shafts (35) to be close to the second and third belt-out shafts (12). As the first and second belt-out shafts (9 and 12) are close to each other, one end of the nylon belt (1) rolls out of the first belt-out device (10), and as the third and fourth belt-out shafts (34 and 35) are close to each other, the other end of the nylon belt (1) rolls out of the outer shell (25) and is installed The belt shell (28) is installed. At this time, the first guide rod (3) engages with the belt guide groove (23) through the guide buckle (24) to drive the connecting buckle (22) to push the middle position of the nylon belt to the front of the car seat. The second connecting rod (4) drives the second magnet (48) and pushes it to the front of the car seat. At this time, the first magnet (21) installed on the connecting buckle (22) and the second magnet (48) installed on the second guide rod (4) are attracted. Then the motor controller controls the first motor (6), the second motor (18) and the third motor (47) to rotate in opposite directions. The first guide rod (3) and the second guide rod (4) are pushed back into the main shell (2). At the same time, the second guide rod (4) drives the connecting buckle (22).The connecting buckle (22) drives the nylon belt (1) to engage and fix with the fixing hook (50) installed in the fixing slot (52). At this time, the three-point safety belt automatically connects to the car seat and the safety belt is automatically connected. Then, the fourth motor (30) drives the plurality of push blocks (27) to push them back into the housing (25). When the separation pressure rod (49) is pressed, the connecting buckle (22) and the fixing hook (50) can be separated. The first spring (56) and the second spring (40) can drive the first belt reel (55) and the second belt reel (41) to retract the two ends of the nylon belt (1).
