CHY100

Actually, 5V, 9V or 12V is controlled by the load (CELL PHONE). The load send signal to D+ and D- of CHY100, and the three resistors connected to V1-V3 can be shorted to ground based on the signal from the load.  I have no idea about the signal of lap top, so I can not answer your question.

how to design the quick charger  with 12V DC or 24VDC input  ?  Is there one schematic circuit diagram for reference? 

 DC input not affect the circuit design around CHY100. Inside the CHY100, there are three internal MOSFET can be shorted to GND based on the signal from D+and D- (from load). Because the resistors connected to V1-V3 will affect the voltage divider, and thus the Vo can be changed based on the load requirement. To select the right resistor value, you have to make sure the following lists:

1. What is the output if no cell phone connected to the charger? If it is 5V,calculate the feedback divider based on 5V output.

2.Based on your loadrequirement,choose the correct resistor value for resistors connected to V1,V2 and V3.

How to design 12/24VDC   input  ,  5V, 9V , 12V output   quick charger   using CHY100 ?

1. calaculate and select  the feedback divider based on the 5V output.

2. Keep the high side feedback divider same, and then then calaculated resistors value of low side divider for 9V and 12V output.

3. Based on the resistor value on step 2 and the lower side feedback divider on step 1, calculate the resistor value connected to the CHY100.

I wonder if this design is right ?   can you help ?

I guess you use Opto to regulate the output, and thus the 12VDC+ is not correct. If I am correct, and your output should be around 5V, 9V and 12V.
