The invention relates to a frame interface for an electric bicycle, comprising a frame element with a first fastening region and a second fastening region, and comprising a fastening element, wherein the first fastening region is provided for the bearing-like fastening of a drive unit on the frame element, wherein the fastening element is fastenable on the second fastening region, wherein the second fastening region has a first clamping surface and the fastening element has a second clamping surface, which are provided for jointly encircling at least one partial region of the drive unit in a ring shape, in order to fasten the drive unit on the second fastening region by means of a clamping force.

This invention relates to the field of new yarn materials technology, and more particularly to a thermally insulating biodegradable PLA napped composite yarn and its preparation method. The yarn uses core-sheath structure PLA filaments as the base yarn, with a core layer of PLA and a sheath layer of low-melting-point PLA or copolymer PLA. The monofilament cross-section is irregular and / or hollow. Air blowing is used to form loop / arc loop pile structures on the surface of the base yarn. Subsequently, under restricted shrinkage conditions, the pile is locked and shaped, with the locking temperature controlled above the sheath softening temperature and below the core melting peak, causing the sheath to soften locally at the contact points to form point-bonding locking points to fix the pile. The pile height quantile, coefficient of variation, and bulk index are detected online, and the airflow, feed difference, and shaping parameters are adjusted in a closed loop to achieve structural and performance stability during continuous production. This solution combines high bulk, high warmth retention, washability retention, and batch consistency.

The invention relates to an electromechanical parking lock actuator (10) for actuating a parking lock (12) in a motor vehicle, comprising: - an electric motor (36) having an output shaft (68), - an actuator shaft (42) which is mounted rotatably or pivotably in a carrier structure (126) and serves to drive directly or indirectly an actuating element (26) which acts on a locking claw (18) of the parking lock (12), wherein the actuator shaft (42) is displaceable between a locking position which corresponds to a locking position of the locking claw (18) and a release position which corresponds to an unlocking position of the locking claw (18), wherein the output shaft (68) of the electric motor (36) is connected actively to the actuator shaft (42) by means of a worm (70), and wherein the parking lock actuator (10) has a blocking device (112) which produces a clearance-free or clearance- accommodating form-fit hold between the carrier structure (126) on one side and the actuator shaft (42) or an element (82) which is connected rotationally fixed to the actuator shaft (42) on the other side at least in the release position of the actuator shaft (42).

The present disclosure relates to a connector assembly defining a longitudinal axis and comprising: an inner connector member comprising a resilient snap arm extending radially outwardly downstream in a mounting direction parallel to the longitudinal axis from an outer surface of the inner connector member; and an outer connector member. The outer connector member comprises a first stop surface and a second stop surface, both perpendicular to the longitudinal axis and aligned in a circumferential direction, the second stop surface being located at a predetermined distance upstream of the first stop surface with respect to the mounting direction.

The utility model provides an experimental device of a POP-Q measuring system based on a guide rail structure, which relates to the technical field of experimental devices and comprises a rack, a three-axis linear motion module, a probe assembly and a control system. The three-axis linear motion module, the probe assembly and the control system are all arranged on the rack; and the control system is electrically connected with the three-axis linear motion module and is used for controlling the three-axis linear motion module to drive the probe assembly to move. According to the utility model, the combination of the hybrid stepping motor and the T-shaped lead screw guide rail is adopted. Compared with a ball screw, the cost of the T-shaped lead screw is lower, the T-shaped lead screw has natural self-locking capacity, the position of the probe can be reliably kept during power failure, the safety redundancy requirement of medical equipment is met, and an additional brake is not needed. The hybrid stepping motor is large in torque and high in positioning precision at a low speed, and the low-speed and precise movement requirements of the system are perfectly met.
