DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention will be described in further detail hereinafter, with reference to accompanying drawings.
FIGS. 1–3 are perspective views illustrating this invention from different viewing angles. The gearshift mechanism according to this invention is provided in a space defined between a left cover 11 and a right cover 12, and comprises: a gearshift lever 2, a slide plate 3, an opening shield plate 4, an opening shield securing plate 5, a switch plate 6, pushbuttons 71, 72, a switch plate affixing shaft 8, and a gearshift lever pivotal pin 9.
The T-shaped gearshift lever 2 is constructed of a lateral grip 21 and a vertical shaft 22 that passes through a slide plate slot 31, an opening shield plate aperture 41, an opening shield securing plate slot 51 and a switch plate slot 61 in order. The gearshift lever pivotal pin 9 transversely passes through a bottom through-hole 23 of the gearshift lever 2 to join to pin openings of the left cover 11 and right cover 12, such that the gearshift lever 2 is able to move forwards and backwards about the gearshift lever pivotal pin 9 in an S-shaped gear channel 13 jointly defined by the left cover 11 and right cover 12.
The slide plate 3 includes a curved rectangular plate, formed with a gear indicator 32 along its left lengthy side. When the slide plate 3 is pushed forwards or backwards by the gearshift lever 2, the child is able to clearly see the gear indicated by the gear indicator 32 through a window 111 provided to the left cover panel. The vertical shaft 22 of the gearshift lever 2 passes through the lateral slot 31 formed on the slide plate 3. The slide plate 3 is formed with four posts 33 extending downwards from a bottom thereof. The posts 33 are formed with inner threads so as to be secured to four corner holes 52 of the opening shield securing plate 5 by screws.
The opening shield plate 4 includes an aperture 41 matched to a diameter of the gearshift lever vertical shaft 22 and is placed beneath the slide plate slot 31, so as to prevent from exposing the opening shield securing plate 5 and switch plate 6 located therebeneath. The opening shield plate 4 is formed with three pegs 42 extending downwards from a bottom thereof to urge against the opening shield securing plate 5 to thereby lean against the bottom of the slide plate 3.
The opening shield securing plate 5 includes a substantially square plate formed with four corner openings 52 to be secured into the slide plate 3 by passing screws upwards into the corner openings 52 and the inner threads within the four posts 33 at the bottom of the slide plate 3. The opening shield securing plate 5 is also formed with a lateral slot 51 through which the vertical shaft 22 of the gearshift lever 2 passes. Beneath a center of the opening shield securing plate 5 is affixed with a U-shaped torsion spring 53. Two ends 531 of the torsion spring 53 are spaced apart by a fixed button 54 provided at a front end thereof to cause the ends 531 to tightly clamp to the vertical shaft 22 of the gearshift lever 2, such that the vertical shaft 22 of the gearshift lever 2 is maintained at the center of the opening shield securing plate slot 51 by means of the torsion spring 53.
The switch plate 6 also includes a substantially square plate formed with a lateral slot 61 at a center thereof through which the vertical shaft 22 of the gearshift lever 2 passes. On opposing sides of the slot are provided with retaining pivotal holes 62 through which flattened switch plate affixing shafts 8 pass to join to apertures 24 formed on the gearshift lever 2 through the pivotal holes 62, such that the switch plate 6 is able to move forwards and backwards along with the gearshift lever 2. The switch plate 6 is provided with a plurality of claws 63 extending downwards from a bottom thereof, for pushing the pushbutton 71, 72.
The advancing/reversing pushbutton 71 and slow/fast pushbutton 72 are embedded in recesses 112 of the left cover 11, where the switch plate 6 moves forwards and backwards along with the gearshift lever 2 subjecting the claws 63 located at the bottom thereof to push one of the pushbuttons 711, 721 for actuating a motor.
With reference to FIGS. 4 and 5, by means of the gearshift mechanism assembled by the above-mentioned components, when the gearshift lever is shifted to the L-gear, the gearshift lever 2 is normal to the switch plate 6. At this time, the claws 63 of the switch plate 6 do not push any of the pushbuttons 71, 72. When the pedal throttle activates the power switch, the electromotive toy car is operated under the mode of slow advancement.
With reference to FIGS. 6 and 7, when the gearshift lever is first maneuvered rightwards and then forwards to reach the D-gear, the gearshift lever 2 will move forwards about the gearshift lever pivotal pin 9 located at its bottom to drive forward movement of the switch plate 6, subjecting the claws 63 located at the bottom of the switch plate to push the pushbutton 721 of the fast/slow pushbutton 72. By activating the pedal throttle to activate the power switch at this time will cause the motor to drive in a forward direction to drive fast advancement of the electromotive toy car.
With reference to FIGS. 8 and 9, when the gearshift lever is maneuvered leftwards and then backwards to reach the R-gear, the gearshift lever 2 will move backwards about the gearshift lever pivotal pin 9 located at its bottom to drive rearward movement of the switch plate 6, subjecting the claws 63 located at the bottom of the switch plate to push the pushbutton 711 of the fast/slow pushbutton 72. By activating the pedal throttle to activate the power switch at this time will cause the motor to drive in a reversed direction to drive slow advancement of the electromotive toy car.
In summary, the gearshift mechanism for electromotive toy car provided in a space defined by the left cover and the right cover, including a gearshift lever, a slide plate, an opening shield plate, an opening shield securing plate, a switch plate, pushbuttons, a switch plate affixing shaft, and a gearshift lever pivotal pin, using the gearshift lever to drive the switch plate to push a pushbutton for actuating a motor, and a pedal throttle to activate a power switch for halting, driving slow advancement, fast advancement or slow reversing of the electromotive toy car, is able to meet children's desires to imitate adults' driving maneuvering through realistic activities.
The above embodiments are intended for describing this invention without limiting the scope that this invention may be applied. Modifications made in accordance with the disclosures of this invention without departing from the spirits of this invention are within the scope of this invention.
