Embodiment Construction
[0019] Please see first figure 1 , the lifting control method of the present invention is implemented through a seat tube assembly 10. The aforementioned seat tube assembly 10 includes a seat tube 12, a seat post 14 that can be axially displaced through the seat tube 12, and a seat post that is arranged on the seat tube 12. The seat cushion 16 at the top of the seat post 14, an air pressure rod 18 located in the seat tube 12, and a motor 20 located in the seat post 14 and connected to the air pressure rod 18, the motor 20 has a drive shaft 22 and a drive shaft 22 located in the drive Lug 26 of shaft 22 . As shown in Figures 2 and 3 again, the lifting control method of the present invention includes the following steps:
[0020] Step a): When the position of the seat cushion 16 is to be adjusted, the rider inputs a valve opening command to a controller 24, and the controller 24 starts the motor 20 after receiving the valve opening command, so that the motor 20 is driven by a ...

The invention provides a lifting control method for a bicycle seat tube. The method comprises the steps that a valve switching-on instruction is input into a controller, the controller starts a motor after receiving the valve switching-on instruction, and the motor is made to drive a pneumatic rod to generate a valve switching-on stroke; after the pneumatic rod reaches a valve switching-on position in the valve switching-on stroke, lifting of the seat tube can start to be adjusted, and meanwhile the controller can control the motor to continuously drive the pneumatic rod to generate a valve switching-off preparation stroke so as to shorten valve switching-off time; finally, a valve switching-off instruction is input into the controller after the seat tube is adjusted to a specified position, the controller can control the motor to drive the pneumatic rod to generate a valve switching-off stroke after receiving the valve switching-off instruction to enable the pneumatic rod to reach a valve switching-off position in the valve switching-off stroke, and then positioning of the seat tube is completed. By means of the method, sensitivity of the seat tube in the positioning process can be improved.
Description
technical field [0001] The invention relates to a bicycle seat tube, in particular to a lifting control method for a bicycle seat tube. Background technique [0002] The height of the bicycle seat cushion is not only related to whether the rider can reduce sports injuries, but also riding the bicycle with the correct posture can make the pedaling action obtain the most labor-saving effect. Since everyone's body is different, most of the seat tube has a height-adjustable design in structure, so that the height of the seat cushion can be properly adjusted to meet the needs of different riders. [0003] As far as the traditional control method of the seat tube is concerned, a controller first starts a motor, and then the motor drives an air pressure rod, so that the air pressure rod produces a valve opening stroke. At this time, the height of the seat post can be adjusted. When the stem is adjusted to an appropriate height, the motor will drive the air rod to generate a valve ...
