Abstract

La présente invention concerne un dispositif de caméra et un dispositif électronique. Le dispositif de caméra comprend un élément de support, un mécanisme d'entraînement, un ensemble de caméra, un cylindre rotatif, un cylindre de levage et un premier élément d'amortissement. Le mécanisme d'entraînement est installé sur l'élément de support, le cylindre rotatif est disposé de manière rotative sur l'élément de support, et le mécanisme d'entraînement coopère avec le cylindre rotatif. Le cylindre rotatif et le cylindre de levage sont manchonnés ensemble, et le cylindre rotatif est utilisé pour entraîner le cylindre de levage afin qu'il monte ou descende pendant la rotation. L'ensemble de la caméra et le cylindre de levage se déplacent l'un par rapport à l'autre dans le sens de l'épaisseur du dispositif de la caméra. Une extrémité du premier élément amortisseur est reliée à l'un des cylindres de levage et à l'ensemble de la caméra, et une autre extrémité du premier élément amortisseur est reliée à l'autre cylindre de levage et à l'ensemble de la caméra. Le premier élément amortisseur remplit une fonction d'amortissement lorsque l'ensemble de la caméra se déplace vers l'élément de support. En conséquence, le dispositif de caméra et le dispositif électronique fournis dans la présente invention peuvent fournir un amortissement contre une force d'impact externe exercée sur la caméra, empêchant ainsi le dispositif de caméra d'être endommagé, et protégeant le dispositif de caméra et le dispositif électronique.
