The bicycle seat tube is usually made of metal because of its better structural strength and hardness, and can be used to bear the weight of the rider. In addition, the bicycle seat tube can be moved relative to the bicycle frame to adjust the height of the seat according to the rider's riding needs and height.

在內部無設置伸降桿的自行車座管，其係透過定位件來定位於車架上，故當欲調整座墊高低時，騎乘者需要將定位件移動至釋放位置，才能調整自行車座管相對車架的凸伸量。然而，此用種調整過程步驟較為瑣碎，且常常無法調整到滿意的高度。Bicycle seat tubes without dropper bars are positioned on the frame by positioning parts. Therefore, when the height of the seat is to be adjusted, the rider needs to move the positioning parts to the release position to adjust the protrusion of the bicycle seat tube relative to the frame. However, this adjustment process is cumbersome and often cannot be adjusted to a satisfactory height.

而在內部設置有伸降桿的自行車座管，其結構包含有控制器、伸降桿及控制線，控制線連接控制器與伸降桿，騎乘者透過控制器牽引控制線藉此來令伸降桿切換於可伸降或不可升降的狀態。然而，透過控制線進行控制，常常有控制線動作延遲、鬆緊度不易調控、斷裂等等問題，且控制線於安裝穿設上也較為麻煩。The bicycle seat tube with a telescopic rod inside includes a controller, a telescopic rod and a control line. The control line connects the controller and the telescopic rod. The rider pulls the control line through the controller to switch the telescopic rod to a state that can be extended or not. However, when controlling through the control line, there are often problems such as delayed control line action, difficulty in adjusting the tightness, and breakage. In addition, the control line is more troublesome to install and wear.

When the screw rotates, When the push member moves along the axial direction of the screw rod, it can selectively press the switch; the driving unit further includes a deceleration mechanism, which is arranged between the motor and the abutting assembly to form a linkage relationship; the deceleration mechanism includes a plurality of deceleration gears, which are respectively engaged with the motor and the abutting assembly; the abutting assembly, the deceleration mechanism and the motor are packaged into a single component; the bicycle seat tube further includes a light-emitting module, which is arranged in the telescopic tube assembly, and a power cord is passed through the threading space to electrically connect the light-emitting module and the circuit board; the abutting assembly is arranged on one side of the motor facing the switch.一種自行車座管升降系統，包含有：一無線控制器，供設於一自行車之一龍頭，可發送一切換訊號；一伸縮管組，包含有一第一管體及一第二管體，該第一管體供定位於該自行車，該第二管體可伸縮地設於該第一管體；一伸縮桿，定位於該伸縮管組之內部用以帶動該第二管體相對該第一管體伸縮，包含有一開關而可切換於一第一狀態及一第二狀態，當該伸縮桿位於該第一狀態時無法進行伸縮，當該伸縮桿位於該第二狀態時可進行伸縮；及一驅動單元，包含有一馬達、一抵靠組件、一電路板及一藍牙接收模組，該抵靠組件連接該馬達且受其驅動移動而可致動該開關切換，該電路板電性連接該馬達，該藍牙接收模組電性連接該電路板以接收該切換訊號；其中，當該藍牙接收模組接收到該切換訊號後，該電路板會傳遞一致動訊號予該馬達，進而該馬達驅動該抵靠組件移動以推抵該開關，令該伸縮桿位於該第二狀態。A bicycle seat tube lifting system includes: a wireless controller, which is provided on a handlebar of a bicycle and can send a switching signal; a telescopic tube assembly, which includes a first tube body and a second tube body, wherein the first tube body is provided on the bicycle and the second tube body is provided on the first tube body in a telescopic manner; a telescopic rod, which is provided inside the telescopic tube assembly and is used to drive the second tube body to extend or retract relative to the first tube body, and includes a switch and can be switched between a first state and a second state. When the telescopic rod is in the first state, it cannot be extended or retracted. When the telescopic rod is in the second state, it cannot be extended or retracted. The second state can be extended and retracted; and a driving unit, including a motor, a supporting component, a circuit board and a Bluetooth receiving module, the supporting component is connected to the motor and driven by the motor to move to activate the switch switch, the circuit board is electrically connected to the motor, and the Bluetooth receiving module is electrically connected to the circuit board to receive the switching signal; wherein, when the Bluetooth receiving module receives the switching signal, the circuit board will transmit an actuation signal to the motor, and then the motor drives the supporting component to move to push the switch, so that the telescopic rod is in the second state.
