Description

Electric bicycle faucet assembly structure with hydraulic control unit (HCU)

The present invention is related to an electric bicycle with an anti-lock braking system (ABS), and more particularly, particularly to the assembly structure of the hydraulic control unit (HCU) of the anti-lock braking system (ABS) and the front of the vehicle.

In order to improve the driving safety of the electric bicycle, preventing the wheel from locking during emergency braking can reduce or avoid the danger caused by the extreme instability of the vehicle body. Anti-lock braking system (Anit-lock Breaking System, referred to as ABS) is to prevent the wheel locking system. The following documents provide relevant disclosures on how the ABS is installed on the electric self-propelled vehicle with limited space structure.

CN209290573U discloses that the ABS control system is installed and connected to the seat tube through an upper connecting frame and a lower connecting frame, and a lithium battery provides power for it through a power cord. When the signal feedback from the sensor is processed by the ABS control system, the ABS pump in the ABS control system changes the oil pressure at a high frequency, and the oil pipe is output to the caliper through the front and rear oil pipe inlet and outlet interfaces, and the oil pipe is output to the caliper to achieve high-frequency spot braking Anti-lock braking effect.

CN111936378A discloses that the hydraulic control unit of the ABS system is arranged on the front fork of the bicycle.

The above two prior art documents describe a common point, that is, the hydraulic control unit of the ABS is not attached to the periphery of the handle. The argument is that although there is more space around the handle, priority should be given to equipment that can be visually recognized by the rider, such as indicators, such as hydraulic control units Devices that require less visual recognition are not preferably arranged around the handle.

The inventor of this case has broken through the above-mentioned limitations, and was approved to file the invention patent TWI735321. TWI735321 sets the hydraulic control unit (HCU) "inside the faucet". The hydraulic control unit does not occupy the periphery of the front of the car, and reserves the peripheral position of the front of the car for equipment that can be visually recognized by the user. In addition, the hydraulic adjustment unit is assembled on the front of the car, which is the position closest to the front brake master cylinder of the electric bicycle. The hydraulic control of the hydraulic adjustment unit can quickly respond to the front brake master cylinder and front caliper, so that the The modulation of wheel braking speed responds quickly, improving the effect of preventing wheel lockup during emergency braking.

In order to make the hydraulic adjustment unit (HCU) and the front of the vehicle have better assembly adaptability, and improve the simplicity and stability of assembly, the present invention proposes a hydraulic adjustment unit 10 (HCU) of an anti-lock braking system (ABS). ) and the assembly structure of the head of the electric bicycle.

The technical feature of the present invention: an electric bicycle faucet assembly structure with a hydraulic control unit (HCU), the bicycle faucet includes: a hydraulic control unit, a handle assembly unit assembled in a handle assembly part outside the hydraulic control unit, and A riser assembly unit assembled in a riser assembly part outside the hydraulic adjustment unit; the handle assembly unit is used for assembling a handlebar of an electric bicycle, and the riser assembly unit is used for a front fork riser of the electric bicycle to pass through extension assembly.

Effect of the present invention:

The structure of the bicycle faucet of the present invention is different from the traditional bicycle faucet (stem, also known as the stem). The traditional bicycle faucet is a tubular body between the handle and the front fork riser, but the present invention uses a hydraulic adjustment unit. Instead of the tubular body of the traditional bicycle faucet, it becomes a bicycle faucet structure equipped with a hydraulic adjustment unit.

The hydraulic adjustment unit does not occupy the periphery of the front of the vehicle, and reserves the peripheral position of the front of the vehicle for equipment that can be visually recognized by the user. In addition, the hydraulic adjustment unit is assembled on the front of the car, which is the position closest to the front brake master cylinder of the electric bicycle. The hydraulic control of the hydraulic adjustment unit can quickly respond to the front brake master cylinder and front caliper, so that the The modulation of wheel braking speed responds quickly, improving the effect of preventing wheel lockup during emergency braking.
