The utility model provides a handle device of a vehicle and the vehicle. The handle device comprises a guide rail, a worm, a rolling assembly and a handle. The guide rail is fixedly connected to a ceiling of a vehicle. The worm is directly or indirectly connected to the ceiling in a rotating mode, extends in the length direction of the guide rail and is spaced from the guide rail. The worm is in transmission connection with active power. The rolling assembly is configured to roll and move on the guide rail under the driving of the worm. The handle is fixedly connected to the rolling assembly. The handle device can meet the requirements of passengers with different heights and arm lengths on handles, and the effect of improving the use experience of the passengers is achieved. Meanwhile, due to the fact that the worm and gear mechanism has a self-locking effect, when the handle is not actively controlled to move, the position of the handle can be maintained, and firm support is provided for passengers.

And the transmission bracket is connected with the linkage motor. The whole driving assembly has the characteristics of compact structure, small size, high torque density and low reduction ratio.

This utility model relates to the field of vehicle technology, and more particularly to a forklift drive wheel assembly and a forklift. The forklift drive wheel assembly provided by this utility model includes a mounting bracket, a drive wheel, and a drive mechanism. The mounting bracket has a first side and a second side facing away from each other. The drive mechanism includes a drive source, a gear reduction assembly, and a planetary gear assembly. The drive source is disposed on the first side of the mounting bracket, and the gear reduction assembly is disposed on the second side of the mounting bracket. The output end of the drive source is connected to the input end of the gear reduction assembly through the planetary gear assembly. The drive wheel is disposed on the first side of the mounting bracket and offset from the drive source, and the drive wheel is connected to the output end of the gear reduction assembly. By using the planetary gear assembly, the reduction ratio can be increased without changing the speed of the drive wheel, thus enabling the gear reduction assembly to adapt to drive sources with low torque, large capacity, and small size. The forklift provided by this utility model can meet the requirements of miniaturization.

The invention discloses an electric zoom lens, which includes a lens barrel, a lens, a focusing mechanism and a detection component; the lens barrel is a hollow structure; the focusing mechanism includes a focusing component and a focusing ring, the focusing component includes a driving member, a slider and a connecting member, the focusing ring is sleeved outside the lens barrel and connected to the lens, the driving member drives the focusing ring to rotate through the slider to adjust the distance of the lens relative to the lens barrel to achieve rapid focusing; the detection component is used to detect the position change during the zooming process of the lens. The present invention can realize accurate detection of position changes during lens zooming, with high reset accuracy; can greatly reduce the number of empty return steps during the focusing process of the electric zoom lens, thereby greatly improving the focusing speed of the current electric zoom lens, and greatly reducing the difficulty of realizing the synchronous focusing function; when focusing, the lens group moves fast, which improves the focusing speed of the lens, the transmission efficiency of the transmission system is high, and the load driving capacity loss is small; and extremely low operating noise can be achieved.
