The present invention relates to a toy car in which a small motor is installed to drive with its force. In particular, when the rear wheel shaft is rotated forward by manipulating the rotation of the modulator, a commercial vehicle moves forward and reversely rotates the rear wheel in the vehicle body. A series of gears and structures that interlock with the shaft allow the entire car to transform into a single robot.

In a conventional toy car, a motor or a spring is mounted inside the vehicle body to drive automatically, but most of them can move forward in only one direction or move forward and backward according to the forward and reverse rotation of the motor. Because there was only a simple function as a car, the children were easily tired and satisfied with their curiosity.

The present invention has been devised in view of this point. By using one motor, it combines the functions of a commercial toy car with the function of a robot to satisfy children's curiosity and play without having fun. I would have to.

When described in detail based on the accompanying drawings as follows.

The driving force of the present invention is a motor (2) mounted in the center front of the inside of the vehicle body (1), the drive gear (3) is provided at the end of the motor shaft (2 ') drawn out of the rear, and the drive gear ( 3) returns the flat gear 4 engaged up therewith, the worm 6 on the same axis 5 rotates the worm gear 8 on the rear wheel shaft 7 so that the motor shaft 2 ' The rotational force is transmitted to the rear wheel shaft.

In addition, on the rear wheel shaft (7) to form a sprocket car (9) and a flat car (10) in order to one side of the worm wheel (8), and to fix the rear wheel (11) at both ends, the rear wheel (11) and A pair of rotating plates 13 and 13 'having the fenders 12 and 12' formed on the rear axle 7 between the body 1 and the outer periphery is provided on the rear axle 7, The connecting plates 15, which are in close contact with each other, are connected to each other so as to be restrained together, and the robot legs 14 and 14 'are respectively formed in front of the bottom thereof.

One of the rotating plates 13 and 13 'is provided with one side of the rotating plate 13 and the bearing hole 16 concentrically with the bearing hole 17, and the upper wall of the rotating plate 13 is composed of a rack 18. (19), and the flat wheel (21) and the spline car (on the fixed shaft 20, which is installed in parallel to the rear wheel shaft (7) inside the vehicle body (1) and formed the pinion (19) at its ends). 22, the flat tooth 21 is fitted to the spline car 9 on the rear wheel shaft 7 and the spline tooth 22 to the flat car 10, respectively, and to the other rotating plate 13 '. The operation rod 23 is protruded on one side of the bearing part 16 ', and the rear end of the operation rod 24 is provided thereon. ) Connect and fix on one end of the assembly.

At the rear of the vehicle body 1, a fixed shaft 29 having a cam gear 27 and a cam 28 is provided at a position slightly out of the center thereof, and the cam gear 27 is placed on a rear wheel 7 on a flat gear. Match with (10).

On the other hand, Figure 6 shows a wheel assembly of the present invention as such, The front wheel shaft 32 having the wheel wheel 31 fixed thereto is fixed to the fixed plate 30 on which the fastener 30 'of the die is formed, and between the wheel wheel 31 and the fixing piece 30 on the wheel wheel 32. The rear end of the robot red bean 33 was adhered to form a wheel assembly, and the wheel assembly was fitted to the groove 34 of the vehicle body 1 to fix the wheel assembly to the vehicle body 1. The tip of the robot arm 33 is positioned between the front lower end of the fenders 12 and 12 'and the robot legs 14 and 14'.

The above-described flat tooth 21 and spline tooth 22 are separated from the fixed ring 35 and remain on the fixed shaft 20, but the spring 37 provided between the fixed ring 36 and the opposite fixed ring 36 has the same. When the pinion 19 is caught by both ends of the activity hole 17 and no longer proceeds, the flat gear 21 and the spline gear 22 only rotate on the fixed ring 35 so as to be electrically driven by the friction force therebetween. The idle gear 8 and the spline tooth 9 on the rear axle 7 also have a fixed ring 38 and a spring 39 on the rear axle 7, thereby eliminating excessive force on the mechanism. However, since the rear wheel shaft 7 receives the most load as the central shaft of power transmission, intermediate wheels 8 'and 9' are formed between the worm gear 8 and the spline gear 9, respectively. The contact surface 40 between them is formed in a sawtooth shape and the pressure of the spring 39 is suppressed. Increase power to ensure power transmission.

Referring to the operating state and effects of the present invention configured as described above are as follows.

When the motor 2 is operated and the motor 2 'is turned, the drive gear 3 provided on the motor shaft 2' turns the flat gear 4 and is on the same axis as the flat gear 4. The rear wheel axle 7 rotates by the worm 6 on (5) turning the worm gear 8.

In this operating state, when the rotation of the motor 2 is operated and the rear wheel shaft 7 is rotated forward, the present invention moves forward as a commercial vehicle as shown in FIG. 3, wherein the pinion 19 is a spline gear (9) and the flat plate 21 is driven on the rack 18, which rotates in the clockwise direction on the drawing, to rotate the rotating plate 3 in the same clockwise direction, but the connecting plate 15 is the body The pinion 19 is caught in the bottom part of (1) and prevents its rotation. Therefore, the pinion 19 is caught in the left end in the activity hole 17, and the flat shaft is stopped while the rotation of the fixed shaft 20 is stopped. 21) and the splicing car 22 only to overcome the friction between the fixed ring 35 and idle.

Therefore, when the rear axle 7 rotates forward, the robot legs 14, 14 'and the connecting plate 15 of the rotating plate 13, 13' are kept in close contact with the bottom of the vehicle body 1 There is no interference to the running of the car, at this time they will look like a decorative part of the car with the robot arm 33 in close contact with the side of the vehicle body (1).

On the contrary, when the rear wheel shaft 7 is reversely rotated, the spline gear 9 integral with the rear wheel shaft 7 returns the flat gear 21 and thus the pinion on the same shaft 20 as the flat wheel 21. Since 19 is rotated counterclockwise in the drawing, this causes the pivot plates 13 and 13 'to also be rotated counterclockwise through the rack 18, wherein the pivot plates 13 and 13' are rotated. The robot leg 14, which is formed integrally with the blade 14, is temporarily retracted for a short time until it reaches the ground, and FIG. 4 shows this moment.

Subsequently, the operation state is as shown in FIG. 5, in which the pinion 19 is racked with the robot legs 14, 14 'contacting the ground and the rotation of the pivoting plates 13, 13' stopped. 18, the vehicle body 1 provided with the fixed shaft 20 fixing the pinion 19 also moves forward in the activity hole 17 in the clockwise direction. 19) rotates clockwise until it reaches the right end of the activity hole 17, and the operating rod 23 protruding from the opposite rotating plate 13 'is in accordance with the standing of the vehicle body (1). Push the rear end of the operation section 24 to expose the robot head 26 fixed to its front end toward the front of the vehicle body 1, and the lower end of the pandas 12, 12 'pushes the robot arm 33 slightly forward. By letting it stand out, the whole car is transformed into a robot.

In such a robot state, the vehicle body is supported by the robot legs 14, 14 ′ and the cam 28 described above, and the cam 28 has a rear wheel shaft 7 in which the cam gear 27 integrally therewith is reversed. The robot is rotated counterclockwise in the drawing, that is, the forward rotation, so that the robot moves forward as if it is walking around with its arms slightly forward.

When the rear wheel shaft 7 is rotated forward by the motor 2 again in the robot state as shown in FIG. The vehicle is allowed to run normally as an automobile through the states shown in FIG. 4 and FIG.

Rotation of the motor shaft 2 'draws electric wires from the motor 2 out of the vehicle body, connects it to a predetermined regulator, and operates the forward and reverse rotation arbitrarily by operating a button of the regulator. Through the process, you can transform it into a car or a robot at will.

As such, the present invention is a toy car that can be transformed into a robot in some cases, which can greatly satisfy the curiosity of children, and has the effect of causing them to play with a fun mind.
