The Difference Between Baby Car 12V And 6V
The Difference Between Baby Car 12V And 6V
The difference between children's electric car 6V and 12V is as follows:according to the drive and one transmission mode、according to the type of drive motor、according to the equipped accessories、by degree of automation.
The overall structure of the electric car:charger, battery, controller, handle. Brake handle, assist sensor.According to the transmission mode.
Press the drive-drive mode:Friction wheel transmission: The friction wheel on the drive machine directly acts on the rubber tire of the rear wheel, and is transmitted by friction.
The structure is simple and the cost is low, but the rotational efficiency is low, the energy consumption is large, the wear damage to the vehicle tires is also large, and it is easy to slip on rainy days.
Shaft sprocket drive type: The drive is specially designed to be mounted on the center axle of the bicycle. The electric bicycle motor with this structure has a reasonable center of gravity, and the transmission efficiency is improved compared with the grinding wheel type, but the mechanical loss is still large, and the transmission efficiency is not high.
Hub drive type: the drive motor is installed in the hub of the rear axle of the car, this hub is similar in shape to the wheel hub of the motorcycle trailer, the size is slightly larger, and the hub is connected to the steel ring through the spokes (steel wire), so as to directly drive the rear wheel to rotate. Its advantages are reasonable design, compact structure, small size, light weight, higher transmission efficiency than the first two, and most electric bicycles are currently used in the driving mode.
By degree of automation：
Standard: It can be used as a bicycle or electrically driven.
Intelligent type: On the basis of the standard type, by improving the intelligence of the control system (using special sensors), the vehicle automatically adjusts the output power (horsepower) of the drive motor according to its driving speed, which prolongs the mileage and motor life, saves effort and power, and avoids traffic risks caused by excessive driving speed as much as possible.
Personally, I feel that it is better to choose a 12V battery, in addition to sufficient power and strong power, when the 12V battery is used up, you can also use the car battery to replace the emergency.Children's electric car mainly refer to a type of toy car driven by an electric motor that children can drive and sit. There are mainly the following categories of children's electric car on the market: electric car, electric motorcycles, electric engineering car, plush toy electric car, etc.
