The mechanical actuation device of the two-wheel toy that the utility model provides, one of two-wheel is connected with motor shaft through gear drive, then its along with motor clockwise, reverse, stop and clockwise, reverse, stop; Two of two-wheel is connected with motor shaft through the forward and backward revolution arrangement of clutch, then follows rotation when a rotation direction of motor, and motor and gear drive break away from when another rotation direction of motor; The rotation of roller two can not be delivered to motor shaft and can make because of the swing of change gear to rotate and stop transmitting through gear drive is directly reverse.Compared with prior art, the utility model two-wheel when a rotation direction of motor is activated simultaneously, can be that to keep straight on also can be that inconsistent arc because of gearratio advances; Then roller two can passively be followed rolling when another rotation direction of motor, and can because the factors such as resistance be made different velocities of rotation, toy be turned under certain radius advance.

The mechanical actuation device of the two-wheel toy that the utility model provides also has a vertical shaft lower end to be connected with motor shaft through the right-angle drive gear train, and the vertical shaft upper end connects the gear shaft of a level again through the right-angle drive gear train, the gear on the gear shaft and vertical rack bar engagement; The housing upper end cover is equipped with fixed guide, and telescopic rail is installed in the fixed guide, and said vertical rack bar is arranged on the telescopic rail, and the guide rail top is hoistable platform; It is the motor forward and backward revolution change-over switch of installing at fixed guide or housing that the forward and backward revolution switching device shifter is arranged in the said motor-drive circuit, and the triggering office of the motor forward and backward revolution change-over switch of installing at telescopic rail.Utilize the right-angle drive gear, namely the power transmission shaft travelling gear that meets at right angles and arrange is delivered to the pinion and rack that the housing top arranges with the rotation in the housing, makes hoistable platform that elevating function be arranged, in order to the parts that need to make lifting action in the toy to be installed.In order to realize that eustasy then installed the travel switch of switch motor forward and backward revolution simultaneously, telescopic rail is descended and when rising to terminal point motor steering be switched.

Description of drawings

Fig. 1 is the structure chart of the utility model one embodiment, and Fig. 2 is the axle system figure of wherein speed reduction gearing, Fig. 3 be among Fig. 2 A to view, among the figure: the 1-hoistable platform, the 2-telescopic rail, 3-tooth bar, 4-gear, 5-fixed guide, 6-right-angle drive gear train, 7-vertical shaft, 8-housing, 9-frame, the 10-motor, 11-roller two, 12-balance salient point, 13-roller one, 14-right-angle drive gear train, 15-driving gear, 16-switches frame, 17-driven gear, 18-clutch gear.

The specific embodiment

One Father christmas toy is comprised of two parts up and down, and upper part has elevating function, and lower part has two-wheel mechanism.Structure is equipped with frame 9 as shown in Figure 1, 2, 3 in lower partial shell 8, mounted motor 10 and speed reduction gearing on the frame.Porose on the chassis, two-wheel also has balance salient point 12 below the chassis through hole supporting on the ground, and a gap is arranged between the bearing-surface on balance salient point lower end and two-wheel and ground, makes and namely plays balanced action, does not hinder again the driving effect of two-wheel.The housing upper end is equipped with fixed guide 5, and telescopic rail 2 is installed in the fixed guide groove, and the telescopic rail upper end is equipped with hoistable platform, and part is fixed on the hoistable platform on the toy.Be provided with vertical rack bar 3 in the telescopic rail, a horizontal teeth wheel shaft is installed take fixed guide as support, gear 4 and tooth bar engagement are arranged on it, this gear has in-line gears through a benzvalene form gear and a vertical shaft 7 form right angle driving gear set 6.This vertical shaft lower end is connected in the transmission device through another right-angle drive gear train 14.In the transmission device in frame, the rotation of motor shaft is through the right-angle drive gear train, roller 1 and the driving gear 15 that slow down, driving gear set is delivered to respectively the vertical shaft lower end.Cover has one to switch frame 16 on the driving gear shaft, switches on the frame clutch gear 18 is installed, and the switching frame can clutch gear then be subjected to the driving gear transmission with the gear shaft rotation when driving gear rotates.The installation site of the driven gear 17 that is connected with roller 2 11 makes it work as clutch gear when switching frame and swing, and swings at one that switches frame that clutch gear meshes with driven gear on the end points, and when swinging to other direction, clutch gear does not mesh with driven gear.

Be installed with a motor forward and backward revolution change-over switch at fixed guide, be provided with the bump of touch switch contact on the telescopic rail.Switch is switched when telescopic rail descends and rises to terminal point.

During work, (initial state is that hoistable platform is in extreme lower position) motor rotates with a direction first, and hoistable platform rises, and two-wheel all is transmitted but one of them rotating speed is lower than another, and then toy is advanced by a larger semidiameter turn.When being raised to when the highest, motor commutation rotates, and hoistable platform descends, and roller one roller two passive rotation that rotate backward, then toy may take the air line and also may advance by the radiuses of different sizes, decides on ground drag, until drop to terminal point.
