Elektromotorischer Wagen für Kinder

摘要

A car includes pairs of front and rear wheels 34 and 36, a seat 12, an electric drive motor 54 to propel the car, a drive unit 52 adapted to drive the car and to turn the car automatically when the load of the motor is increased due to an obstacle. The car further includes a control circuit (110 fig 7) for controlling the speed of the car, producing various melodies and to detect an overcharge and overdischarge of a battery (108 fig 6). Preferably, the car is provided with a steering unit 26 which comprises a steering wheel 28, a shaft 30 having a spring receptacle 46 in which a spring 40 is contained, first and second driven gears 42 and 44 cooperated with the shaft 30. In the drive unit 52, a gear 74 is provided at an upper periphery of a housing 66 and engaged with the second driven gear 44. The housing 66 can be turned due to the increased load of the motor 54 so that the car can avoid obstacles in the running direction thereof. Drive is transferred from the motor to the wheels 72 via bevel gears 62, 64. The axle 70 upon which the wheels 72 and bevel gear 64 are mounted passes through holes (68 fig 4) in the housing 66. The car may employ a sensor to detect obstacles which may then be avoided.
