Lens focal length adjustable VR camera

Abstract

The invention discloses a lens focal length adjustable VR camera. The camera comprises a casing and a lens barrel, the bottom inner wall of the casing is provided with a motor, the motor is positioned at one side of the casing, an output shaft of the motor is connected with a screw, the screw is provided with third threads, the side, far from the inner wall of the casing, of the motor is provided with a sliding seat, the four corners of the bottom of the sliding seat are provided with first sliding columns respectively, the first sliding columns are in sliding connection with a chute, the chute is placed in the bottom inner wall of the casing, the side, close to the motor, of the sliding seat is provided with a fourth circular fixing hole, the inner wall of the fourth circular fixing hole is provided with fourth threads, the fourth threads cooperate with the third threads, the top of the sliding seat is provided with two support columns, the support columns are positioned in the two sides of the sliding seat respectively, and an image surface is arranged over the sliding seat. The VR camera is simple in structure, lower in cost, economical and practical, and the focal length of a lens in the VR camera is convenient to adjust so that the VR camera has a good shooting effect.

Description

technical field [0001] The invention relates to the technical field of VR cameras, in particular to a VR camera with adjustable lens focal length. Background technique [0002] The full name of VR is "Vibration Reduction". The anti-shake principle of VR cameras is basically the same as Canon's IS anti-shake system. They both use floating lenses in the lens to correct "optical axis offset". The electronic vibration reduction system in the lens detects the slight vibration of the lens, and corrects the position of the lens inside the lens in real time, effectively reducing the impact of external vibration on the final camera imaging. The focal length of the lens inside the existing VR camera is It cannot be adjusted, and thus cannot meet people's higher needs, making the VR camera's shooting effect poor. Contents of the invention [0003] The object of the present invention is to propose a VR camera with adjustable lens focal length in order to solve the shortcomings in the...
