摘要： A shock absorbing device may include a housing, a piston, and membrane. The housing may define space. The piston may move within the space to adjust a pressure of a gas in a main spring chamber to form a gas spring. The piston and the housing may partially define the main spring chamber within the space. The membrane may be positioned in the space. The housing and the membrane may define a secondary spring chamber within the space. The membrane may partially define the main spring chamber and may be sufficiently elastic such that when the piston adjusts the pressure of the gas in the main spring chamber, a force applied on the membrane by the gas in the main spring chamber changes and causes the membrane to selectively deform to adjust a pressure of gas in the secondary spring chamber to control a spring rate of the gas spring.

摘要： A hidden-type shock absorbing bicycle frame has a front vehicle frame, a transmission assembly, a rear vehicle frame, and a damper. The front vehicle frame has a seat tube having two assembly plates. The assembly plate has an upper pivot hole and a lower pivot hole. An assembly space is formed between the assembly plates. The transmission assembly is pivotally connected to the upper pivot holes and has two front arms located in the assembly space and two rear arms located at two sides of the seat tube and extending backwardly. The rear vehicle frame is pivotally connected with the rear arms and is pivotally connected with the seat tube. The damper hidden inside the assembly space has a top end pivotally connected with the front arms and a bottom end pivotally connected to the lower pivot holes.

摘要： A telescopic apparatus for a human-powered vehicle comprises a first hydraulic chamber, a second hydraulic chamber, a valve member, a cam member, and an actuator. The second hydraulic chamber is configured to be in fluid communication with the first hydraulic chamber. The valve member is configured to control a fluid communication between the first hydraulic chamber and the second hydraulic chamber. The cam member is rotatable about a rotational axis to move the valve member in a movement direction. The actuator is configured to rotate the cam member. The actuator includes an output shaft rotatable about an actuation rotational axis. The actuation rotational axis is offset from the rotational axis as viewed in the movement direction.

摘要： Techniques are disclosed for systems and methods associated with a powertrain for a micro-mobility fleet vehicle. The fleet vehicle may include at least one drive wheel to provide tractive contact between the flee vehicle and a road surface, an electric motor mechanically coupled to the drive wheel and configured to provide motive force for the fleet vehicle, a brake resistor configured to provide dynamic braking of the motor, and a motor controller electronically coupling the brake resistor to the motor. The motor controller may be configured to control the motive force provided by the motor using the brake resistor. The motor controller may be configured to limit a speed, power, and/or acceleration of the motor using the brake resistor based on an operational environment of, and/or on a directive received by, the fleet vehicle. The brake resistor may provide a relatively wide range of traction control for the fleet vehicle.
