Abstract

A toy vehicle that is battery powered and driven by an electric motor mounted on the vehicle. The toy vehicle is designed for high and low speed operation in both a two-wheel drive mode and a four-wheel drive mode, as well as having a free wheel mode where the wheels are not in driving engagement with the electric motor. Thus the toy vehicle has at least five operating modes: 1) a higher speed two-wheel drive mode; 2) a lower speed two-wheel drive mode; 3) a higher speed four-wheel drive mode; 4) a lower speed four-wheel drive mode; and 5) a free wheel mode. Providing the toy vehicle with all of these operating modes makes the vehicle more interesting to children. In addition, the front end of the toy vehicle is designed to light up thereby increasing the visual appeal of the vehicle, especially for children. Further, the toy vehicle employs a unique electrical connection between the battery and the electric motor that does not require soldering or wiring, thereby simplifying assembly of the vehicle. Furthermore, a light bulb associated with the vehicle is electrically wired to the battery using clips, thereby eliminating the use of soldering.

Claims

1. A toy vehicle, comprising:

a chassis;

front and rear axles rotatably mounted on said chassis, and a pair of wheels connected to each said axle;

an electric motor mounted on said chassis, said electric motor including a driveshaft for driving said front and rear axles; and

means for selectively driving both of said front and rear axles at a first speed and a second speed, and for driving only one of said front and rear axles at the first speed and the second speed while the other of said front and rear axles is not driven.

2. The toy vehicle according to claim 1, further comprising a vehicle body detachably connected to said chassis, said vehicle body including a front end;

and a transparent light bar is detachably connected to said vehicle body adjacent said front end.

3. The toy vehicle according to claim 1, wherein said electric motor includes a metal shell, and a terminal mounted on the motor having a negative contact connected to the metal shell and a positive contact;

and further comprising a metal strip mounted on said chassis and having a first end adapted for engagement with a battery and a second end adapted for engagement with the positive contact.

4. A toy vehicle, comprising:

a chassis;

front and rear axles rotatably mounted on said chassis, and a pair of wheels connected to each said axle;

an electric motor mounted on said chassis, said electric motor including a driveshaft;

front and rear gear mechanisms for driving said front and rear axles, respectively, said front and rear gear mechanisms each providing a first speed and a second speed, and each said front and rear gear mechanism being actuatable between a freewheel mode at which the front and rear axles are not driven, a first speed mode at which the front and rear axles are driven at the first speed, and a second speed mode at which the front and rear axles are driven at the second speed;

front and rear shift mechanisms connected to the front and rear gear mechanisms, respectively, for actuating the front and rear gear mechanisms between the freewheel mode, the first speed mode and the second speed mode, said front and rear shift mechanisms being slideable relative to the chassis to actuate the front and rear gear mechanisms; and

a connector engaged with the front and rear shift mechanisms, said connector being moveable between a first position and a second position, said front and rear shift mechanisms being slideable together at the first position of the connector and said front and rear shift mechanisms being slideable relative to each other at the second position of the connector.

5. The toy vehicle according to claim 4, wherein said driveshaft is a double-ended driveshaft having a front portion extending from one end of the motor and a rear portion extending from an opposite end of the motor;

and said front and rear gear mechanisms comprise a front worm and a rear worm mounted on the front and rear portions of the driveshaft, respectively, and first and second gears slideably disposed on each of the front and rear axles and engageable with the front and rear worms.

6. The toy vehicle according to claim 5, wherein said front and rear gear mechanisms further comprise front and rear intermediate compound gear assemblies mounted on shafts that are parallel to said front and rear axles, each said intermediate compound gear assembly including a worm gear engaged with a respective one of said front and rear worms, and first and second intermediate gears mounted on opposite sides of said worm gear and engageable with said first and second gears disposed on a respective one of said front and rear axles.

7. The toy vehicle according to claim 5, wherein said first and second gears on each of said front and rear axles include collars that engage each other whereby the first and second gears contact each other, and said front and rear shift mechanisms are engageable with said first and second gears whereby said first and second gears are shifted along the respective said front and rear axles upon sliding movement of said front and rear shift mechanisms.

8. The toy vehicle according to claim 4, wherein said connector is slideable with said front and rear shift mechanisms when said connector is at the first position.

9. The toy vehicle according to claim 4, wherein said rear shift mechanism is slideable and said front shift mechanism is fixed when said connector is at the second position.

10. The toy vehicle according to claim 4, further comprising a vehicle body detachably connected to said chassis, said vehicle body including a front end;

and a transparent light bar is detachably connected to said vehicle body adjacent said front end.

11. The toy vehicle according to claim 10, wherein said light bar includes a plurality of projections thereon, and the front end of said vehicle body includes holes extending therethrough into which said projections extend.

12. The toy vehicle according to claim 10, wherein said light bar includes a flange extending under the front end of the vehicle body.

13. The toy vehicle according to claim 10, wherein said vehicle body includes posts connected thereto, and said light bar includes tabs that are connected to said posts.

14. The toy vehicle according to claim 4, wherein said electric motor includes a metal shell, and a terminal mounted on the motor having a negative contact connected to the metal shell and a positive contact;

and further comprising a first metal strip mounted on said chassis and having a first end adapted for engagement with a battery and a second end adapted for engagement with the positive contact.

15. The toy vehicle according to claim 14, further including a light bulb mounted on said chassis, and a second metal strip mounted on the chassis, said light bulb being electrically connected adjacent to the first end of said first metal strip and to the second metal strip, and an end of said second metal strip being engaged with the metal shell of said electric motor.

16. The toy vehicle according to claim 15, wherein said light bulb includes a pair of light bulb wires, and said first metal strip and said second metal strip each include clips formed thereon connecting the light bulb wires thereto.
