Disclosed are a winch, a rope guide, and a transmission device having a clutch function. The winch includes a base seat, a reel, a rope guide, a transmission assembly, and a motor. The reel is rotatably provided to the base seat. The rope guide is provided to the base seat. The transmission assembly is connected with the rope guide. The motor is connected with the reel to drive the reel to rotate, and the motor drives the rope guide through the transmission assembly. In the winch according to embodiments of the present disclosure, the rope guide is an active rope guide, bringing about a good rope guiding effect. Moreover, the reel and the rope guide are driven by the same motor, which reduces the number of components and parts, simplifies the structure and control, and lowers costs.

Winch, rope guide and transmission device having clutch function

The present disclosure relate to a vehicle running board apparatus and a retractable device thereof. In some embodiments, a retractable device includes a running board holder and an arm assembly. The running board holder has a connecting portion, and the arm assembly is configured to drive the running board holder to move between an extended position and a retracted position. The arm assembly includes a first arm and a second arm. The first arm has a first end and a second end. The second end of the first arm is pivotally connected to the connecting portion of the running board holder. The second arm has a first end and a second end. The second end of the second arm is pivotally connected to the connecting portion of the running board holder. The second end of at least one of the first arm or the second arm straddles the connecting portion.

Vehicle running board apparatus and retractable device thereof

Embodiments of the present disclosure disclose a vehicle step apparatus and a vehicle. The vehicle step apparatus includes a step, a retractable device, and a locking member. The step is movable between an extended position and a retracted position. The retractable device is connected to the step and configured to drive the step to move between the extended position and the retracted position. The locking member is configured to lock the step in the retracted position or to allow the step to move away from the retracted position towards the extended position.

Vehicle step apparatus and vehicle

An adjustment device includes a body, an adjustment inner gear ring, and an adjustment shaft. The body has a cavity therein, has a first end provided with a first hole and a second hole, and has a peripheral wall provided with a third hole. The first hole, the second hole, and the third hole are connected with the cavity. The adjustment inner gear ring is fitted in the cavity, and has a peripheral wall provided with adjustment holes. The adjustment holes have different cross-sectional areas. A second end of the adjustment shaft has an adjustment gear and passes through the second hole into the cavity. The adjustment gear meshes with the adjustment inner gear ring. The adjustment shaft is rotatable to drive rotation of the adjustment inner gear ring so as to enable the third hole to be connected with the cavity through one of the adjustment holes.

Adjustment device, adjustor and shock absorber

A running board device comprises a stationary running board; a retractable running board apparatus comprising a retractable mechanism moveable between a stretched position and a retracted position and a retractable running board mounted to the retractable mechanism, wherein at the stretched position, at least a part of the retractable running board stretches out below the stationary running board and beyond the stationary running board, and at the retracted position, the retractable running board is retracted into below the stationary running board.

Running board device and vehicle having the same

Provided is a vehicle step apparatus comprising a first extending and retracting device comprising a first mounting bracket, a first step bracket, and a first arm assembly coupled between the first mounting bracket and the first step bracket and configured to drive the first step bracket to move between an extending position and a retracting position; a second extending and retracting device comprising a second mounting bracket, a second step bracket, and a second arm assembly configured to drive the second step bracket to move; a step mounted on the first step bracket and the second step bracket; a single motor mounted on the first mounting bracket and having a motor shaft coupled with the first arm assembly; and a transmission shaft defining a first end coupled with the motor shaft, and a second end coupled with the second arm assembly via a braking device.
