Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a forward and backward control mechanism for a toy car.

[0002]

[Prior art]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Please refer to FIG. According to one embodiment of the present invention, a forward and backward control mechanism for a toy car is provided with a polygonal shaft 111 having an appropriate length provided on a transmission shaft 11 having a circular cross section, and both ends of the transmission shaft 11 are respectively provided on both ends of the toy car. It is connected to both front wheel systems (not shown in the drawing). The transmission shaft 11 can rotate freely while being supported by the bearing.

A first fixed gear 13 and a second fixed gear 16 are respectively attached to the transmission shafts 11 at both ends of the polygonal shaft 111, and the first fixed gear 13 and the transmission shaft 11 have slack and rotate relative to each other. can do. The first fixed gear 13 is provided with external teeth 131 arranged on the circumference of the outside diameter and internal teeth 132 arranged on the circumference of the inside diameter. In a preferred embodiment, the number of the internal teeth 132 is seven. Designed for The second fixed gear 16 also has external teeth 161 arranged on the outer circumference and internal teeth 162 arranged on the inner circumference. The number of the internal teeth 162 is designed to be seven. The first fixed gear 13 is connected to the passive gear 12, the passive gear 12 is meshed with the active gear 31, and the active gear 31 is connected to the engine 3.

A movable gear 14 is attached to a polygon shaft 111 of the transmission shaft 11, and the movable gear 14 can freely move the polygon shaft 111 in the axial direction. The movable gear 14 cannot rotate relative to the transmission shaft 11 due to the effect of the combination with the hole. The number of teeth of the tooth portion 141 distributed on the outer diameter of the movable gear 14 is designed to be seven. When the movable gear 14 moves in the axial direction on the polygonal shaft 111, the teeth 141 mesh with the internal teeth 132 of the first fixed gear 13 or the internal teeth 162 of the second fixed gear 16 (shown in FIG. 5). Since there is a sufficient gap between the teeth 141 and the internal teeth 132 or 162, the teeth 141 can be easily engaged with the internal teeth 132 or 162 when the movable gear 14 moves in the axial direction.

The present invention further includes a first idle gear 15 and a second idle gear 17. The first idle gear 15 is meshed with the external teeth 131 of the first fixed gear 13, and at the same time, the second idle gear 17 is It meshes with the external teeth 161 of the first idle gear 15 and the second fixed gear 16.

The control device for a toy car according to one embodiment of the present invention is further provided with a servo mechanism 2, the servo mechanism 2 is provided with a swinging arm 21, and the swinging arm 21 is provided with a first link. The rod 22 is pivotally connected, the first connecting rod 22 is further connected to the second connecting rod 23, and the second connecting rod 23 is connected to the movable gear 14.

The mechanism of the control device for a toy car according to one embodiment of the present invention is controlled and operated mainly by a remote controller, whereby the swing of the swingable arm 21 is controlled. The double rods 22 and 23 are interlocked, and the movable gear 14 is further driven by the second rod 23 to move in the axial direction on the polygonal shaft 111. When the movable gear 14 is switched to the state shown in FIGS. 2 and 3, the passive gear 12 is rotated by the active gear 31 driven by the engine 3, and the first fixed gear 13 is rotated in the forward direction by the passive gear 12. The first idler gear 13 further drives the first idler gear 15 to rotate in the reverse direction, and the first idler gear 15 drives the second idler gear 17 to rotate forward. The second fixed gear 16 is further driven by 17 to rotate in the reverse direction, and the internal gear 162 of the second fixed gear 16 drives the movable gear 14 to rotate in the reverse direction. Since the transmission shaft 11 cannot rotate relative to each other, the transmission shaft 11 can be driven backward.

When the movable gear 14 is switched to the state shown in FIG. 4, the teeth of the movable gear 14 have already meshed with the internal teeth 132 of the first fixed gear 13, so that the first fixed gear 13 is passive. The gear 12 rotates forward by the driving of the gear 12, and further proceeds to be driven by the movable gear 14 so that the transmission shaft 11 rotates forward, so that the remote control vehicle moves forward. In this case, the first and second idler gears 15 and 17 and the second fixed gear 16 are idle.

In the design of the present invention, the function of switching between forward rotation and reverse rotation of the wheel can be achieved with a small number of gear mechanisms, so that the overall volume of the mechanism can be significantly reduced, and the weight is reduced. Therefore, it can be said that the design is economical because the manufacturing cost can be reduced.
