The present invention relates to a steering device for a four-wheeled vehicle toy (mainly a skateboard toy controlled wirelessly or by wire).

Normally, the steering wheel of the four-wheeled toy, which is powered by a battery and a small motor is operated wirelessly or by wire, and rotates forward, backward, left and right, consists of a combination of various mechanisms inside the front of the toy. As it is rotated from side to side, it is possible to turn left and right of car toys, but toys that put upright dolls such as skateboard toys have no problem when moving forward and backward. Because they stand without support, they fall down in the opposite direction due to the centrifugal force caused by the car's rotation.

The present invention improves these points, so that the steering and the center movement of the vehicle are made at the same time as the composite movement, and the center of the toy is maintained while the upright doll is inclined in the rotational direction. The movement is natural and lively.

This will be described in detail based on the accompanying drawings.

Receiving and transmitting signals by wireless or wired device, power supply unit (S) with built-in battery, drive unit (P) with driving motor and reducer, steering unit (T) with steering device, and doll (D) In the conventional four-wheeled toy constructed on the bottom of the chassis 1 fixed to the upright, the steering portion T is separated into the upper plate 2 and the lower plate 3, and the stationary motor (inside the lower plate 3) is provided. M) has a built-in left and right wall surface (7) (7 ') on one side with the front part of the pivoting rod (5) inserted into the outer periphery of the pivoting plate (4) struck by the motor shaft (10). On the other side of the swing hole 6, an upward protrusion 8 is protruded, and the left and right auxiliary levers 12 'are inserted into the insertion protrusion 11' on the upper portion of the square shaft 11 inserted into the square through hole 9 of the center. 12 ') of the heads 13 and 13' are overlapped and inserted, and their legs 14, 14 'are positioned upward and downward on the left and right inner surfaces of the lower plate 3 and the upward protrusions in front of the swing shaft 30 and the swing hole 6, respectively. 8) so that it faces the pin 8 16) and fixed to the center of the wheel shaft 18, the rotating shaft 17, which is addressed to the lower jaw (17 ') in the lower portion of the square shaft (11), grooves fitted to the rear of the rotating rod (5) Horizontal bar 22 is protruded on the front surface of the swinging piece 20 having the bottom portion 21 formed thereon, and pressure protrusions 23 and 23 'are formed on the upper left and right sides thereof, and a central part thereof is inserted into the horizontal axis 19. The head 25, 25 'of the left and right auxiliary levers 24, 24' is biaxially inserted on the biaxial axis and the springs 27 are supported so that they face the shoulders 26, 26 'with the crossbars 22 and the legs. (28) (28 ') end is disposed so as to be restrained to the outside of the projections 31, 31' protruding from the bottom of the lower plate (3), the pressing protrusions (23, 23 ') on the upper swing pin (20) The upper plate 2 is attached to the lower plate 3 so as to contact the bottom surface of the chassis 1 through the operation hole 2 '.

Reference numeral 33 is a support piece.

The steering and center movements are composed of the composite movement by the center movement configuration of the steering device and the chassis. The forward / reverse motor (M) is operated by an electric signal by wireless or wired, and when the motor rotates left when viewed in the forward direction of the toy, the rotating plate (4) Rotating bar (5) pushes the right wall (7 ') of the lower side of one side of the swinging hole (6) while the left side of the swinging hole (6) around the insertion stone (11') Will rotate.

Therefore, the wheel shaft 18 is to turn left, the left auxiliary lever 12 of the upper swing hole 6 is pushed to the left by pushing the upward protrusion bar 8, the right auxiliary lever 12 'is the spring 15 It is restrained on the projection 30 in front of the lower plate 3 by the sieve, and is in place.

Simultaneously with this operation, the swinging piece 20 in which the groove 21 is inserted into the rear portion of the pivoting rod 5 is swung to the right about the horizontal axis 19 so that the right joining protrusion 23 ′ pushes the bottom surface of the chassis 1. The undercarriage 1 is inclined leftward about the horizontal axis 19 supported by the support piece 33.

At this time, the side stone bar (5) is rotated along the oscillation piece 20 while pushing the shoulder (26 ') of the right auxiliary lever (24') and the left auxiliary lever (24) is a protrusion in which the lower end of the leg protrudes on the bottom plate (3) Restrained outside of 31 to remain in place.

As the above operation is performed at the same time, while the toy rotates to the left, the doll 1 and the doll D standing upright on the upper surface thereof are inclined in the left direction, that is, the direction of rotation, and the center of the toy is maintained.

The right turn is made by the reverse action of the above, and the auxiliary levers 12, 12 ', 24 and 24', which are supported by the springs 15 and 27, respectively, are formed of the swing hole 6 and the swing piece 20. In the case of assisting rotation and swinging, and turning right and left again and going straight again, the swinging hole 6 and the swinging piece 20 are returned to their original positions by the spring force of the springs 15 and 27 without the battery being consumed. do.

As such, the present invention maintains the center of the entire toy even when rotating left and right, such a state brings about a natural and lively reality and minimizes the consumption of the battery.
