Title: The Innovative Contributions of Jian-Jun Zhang

Introduction

Jian-Jun Zhang is a prominent inventor based in Guangdong, China. He has made significant contributions to the field of optical technology, particularly in the development of advanced zoom lens systems. With a total of seven patents to his name, Zhang's work has had a considerable impact on the industry.

Latest Patents

Zhang's latest patents include a zoom lens adjustment structure and a zoom lens design. The zoom lens adjustment structure features a substrate, a focus device, and a driving device. The focus device is mounted on the substrate and includes a stationary lens barrel, an outside guide lens barrel, and a cam lens barrel. The outside guide lens barrel is received in the stationary lens barrel, while the cam lens barrel is set on the inner side of the outside guide lens barrel. A plurality of active lens barrels is sandwiched between the outside guide lens barrel and the cam lens barrel, with each active lens barrel containing a lens set. The driving device consists of a motor and a gear group, positioned laterally to the stationary lens barrel, which drives the focus device to adjust the position of the active lens.

The zoom lens patent includes a fixing barrel, a cam barrel, a guide barrel, and three lens groups. The cam barrel is rotatably received in the fixing barrel, while the guiding barrel is movably received in the fixing barrel and partially receives the cam barrel. The guiding barrel moves along the optical axis of the zoom lens, following the motion of the cam barrel. The first lens group is rotatably received in the guiding barrel, and the second lens group is rotatably received in the cam barrel. Both lens groups move along the optical axis in response to the rotation of the cam barrel. The third lens group is aligned with the first and second lens groups and is driven by a driver to be movably received in the fixing barrel.
