The car mobile phone holder is mainly used by motorists, making it safer to answer calls while driving.
The composition of the car bracket is mainly divided into four parts: electric drive system, mobile phone clamp arm, bracket base, and power supply system.
Power system in the bracket with overcapacity
The power system generally consists of a battery and a charging line. The battery can provide power to the stand, and at the same time support the charging line to ensure the continuous use of the stand, and the charging line can be charged by the charger or car power supply.
At present, the power supply used in the bracket is mainly divided into lithium batteries and supercapacitors. Their use scenario is that when the power is cut off and the stand cannot be charged, the drive motor ensures the normal use of the clamp arm, which has achieved the purpose of convenient access to the mobile phone.
Comparison of supercapacity with lithium batteries
The super capacity can be recharged 50~1 million times, and there is almost no need to replace the battery or product.
High super-capacitive power density. It can amplify the current in a short time, so that the clamp arm can be quickly opened and retracted, and the product experience is better.
Lithium batteries can only be recharged hundreds of times. In the event of frequent power and power failure, the service life of the product will be greatly reduced
The power density of lithium batteries is not enough, the life is not enough, and long-term use will cause the expansion and contraction of the clamp arm to slow down, affecting the experience.
