Generally around 7cm- 10cm.
Cup holder is an indispensable element in automobile functional design. The first patent of automobile cup holder was approved, but it was only an additional accessory at that time. In 1950s, drive-in restaurants and drive-in cinemas began to spread on a large scale, which really enhanced the popularity of cup holders.
At first, there was no room for cup holders in small cars, especially those with manual gears (which can also be understood as entry-level models). The gear shifting device occupies a considerable space in the car and requires the driver to control the car with both hands all the time, so the cup holder didn't look practical at that time.
Precautions:
1. After unpacking, according to the tuyere of the vehicle model, choose the appropriate tuyere clip (there are two pairs, one large and one small, which is very intimate) for installation.
2. On high-end models, the cup holder has the function of heating or cooling, which is not a rare configuration. The 300C cup holder can provide heating and cooling functions at the same time, that is, heating on the left and cooling on the right, or heating on the left and cooling on the right, and preparing hot and cold drinks at the same time as needed.
3. Use two building blocks with clamping teeth to separate cup holder spaces with different sizes for placing cups with different sizes.
