When the equipment needs to be moved, the main motor 16 is started, the centrifugal wheel 20, the right bevel gear 19 and the left bevel gear 35 are driven to rotate by the starting of the main motor 16, the centrifugal wheel 20 rotates to enable the centrifugal block 21 to be thrown out outwards under the action of centrifugal force to push the rack 10 on the upper side of the centrifugal block, so that the main motor 16 is driven to move downwards under the action of the reaction force of the centrifugal wheel 20 and overcome the tension of the shaft sleeve return spring 24, the right bevel gear 19 is disengaged from the lower bevel gear 23 and is meshed with the transition bevel gear 27, the main motor 16 drives the right bevel gear 19 to rotate the transition bevel gear 27, the transition bevel gear 27 rotates to drive the moving bevel gear 29 to rotate the axle bevel gear 33, and the axle bevel gear 33 rotates to drive the wheels 30 to move the equipment, if the tire pressure monitor 31 detects a problem in tire pressure during movement, the secondary motor 61 is controlled to be started, the secondary motor 61 is started to drive the cam 58 to rotate, so that the brake auxiliary plate 56 moves up and down in a reciprocating manner, the up and down movement of the brake auxiliary plate 56 pushes the auxiliary plate return spring 55 to periodically rub against the auxiliary brake disc 34, so as to reduce the vehicle speed at equal intervals to prevent the danger of vehicle runaway caused by direct braking, when the equipment stops working and a driver is not in the equipment, as the temperature in the driving cab 13 gradually rises, the limiting hydraulic cylinder 26 is extended by triggering the temperature sensor 46, so that the resisting plate 25 resists against the lower side of the centrifugal wheel 20, and the main motor 16 is started to drive the centrifugal wheel 20 to rotate, but the upper side and the lower side of the main motor 16 are resisted against, so that the main motor 16 is not moved downwards under the action of the centrifugal block 21, at this time, the main motor 16 drives the right bevel gear 19 to rotate the lower bevel gear 23, the rotation of the lower bevel gear 23 drives the inner wheel 59 to rotate through the inner shaft 40, the rotation of the inner wheel 59 drives the rotation pin 15 to rotate through the fixed pin 62, the rotation of the outer wheel 42 drives the reel 41 fixedly connected with the outer wheel to rotate, the reel 41 rotates to pull the pull wire 43 to unfold the elastic sunshade curtain 44 downwards to shield the front transparent glass of the device, when the inner shaft 40 is completely unfolded, the reel 41 cannot rotate continuously because the elastic sunshade curtain 44 cannot be unfolded continuously, at this time, the rotation of the inner shaft 40 causes the fixed pin 62 to rotate the rotation pin 15 through an angle against the elastic force of the torsion spring 60, so as to ensure that the inner wheel 59 and the outer wheel 42 can rotate oppositely, thereby ensuring that the device is not locked, and when there is a baby on the child seat 47, the trigger plate 51 is pressed to move the push rod 48 downwards, the downwards movement of the push rod 48 pushes the middle auxiliary block 50 to make the balance bar 39 stretch the auxiliary block return spring 64 downwards, so that the auxiliary bevel gear 36 is engaged with the left bevel gear 35, and the spline housing 80 is engaged with the upper side of the worm 79, at this time, the main motor 16 is started to drive the left bevel gear 35 to rotate the auxiliary bevel gear 36, so that the spline housing 80 drives the worm 79 to rotate, the worm 79 rotates to drive the worm wheel 78 to rotate the blower fan 74 and the lower pulley 76, the lower pulley 76 rotates to drive the upper pulley 63 through the belt 77, so that the blower fan 74 on the upper side rotates, the rotation of the blower fan 74 can make the outside air sucked through the air inlet channel 81 and filtered by the filter screen 73 to be introduced into the cab 13, thereby achieving the purposes of reducing the temperature in the vehicle and providing fresh air, and avoiding the accident caused by the carelessness of the infant.

The invention has the beneficial effects that: this device makes it can be automatic when the high temperature pull down elasticity sunshade screen through the judgement to the interior temperature of car to reduce indoor temperature, and still can carry out the air feed through the fan of blowing when having the baby in the driver's cabin, thereby further reduce the temperature in the driver's cabin and guarantee the fresh of air, and can pass through the detection to tire pressure at the in-process that equipment removed, make at the tire pressure problem thereby the periodic friction auxiliary brake dish of arc clutch blocks reaches the purpose that makes equipment slow down under the prerequisite of guaranteeing safety, and this device degree of safety is high, and degree of automation is high, can protect baby's safety, is worth widelys popularization, production and use.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
