An electronic device and its distance adjustment mechanism

Abstract

The application discloses a distance adjustment mechanism, comprising: a rotating wheel; a first part, which is eccentrically connected with the first end face of the rotating wheel, and is driven to perform linear reciprocating motion when the rotating wheel rotates in one direction; a second part, which is connected to the rotating wheel The second end surface of the wheel is eccentrically connected, and is driven to perform linear reciprocating motion when the rotating wheel rotates in one direction. The motion tracks of the two parts are parallel or coincident, and the first connection point of the second part and the rotating wheel is connected with the second part and the rotating wheel. The second connection points of the rotating wheels are arranged in a staggered manner. The above-mentioned distance adjustment mechanism realizes the change of the distance between the first part and the second part through the one-way rotation of the rotating wheel, so no matter in which direction the user turns the rotating wheel, the distance can be increased or reduced. There is no misoperation phenomenon, and there is no limit position in the way of rotation adjustment, so that the probability of damage to the distance adjustment mechanism has also been significantly reduced. The present invention also provides an electronic device with the above-mentioned distance adjustment mechanism.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a distance adjustment mechanism, and also relates to an electronic equipment with the distance adjustment mechanism. Background technique [0002] On some electronic devices, a distance adjustment mechanism for adjusting the distance between the functional parts and the supporting parts is provided. The positions of the corresponding two optical machines on the frame are used to realize the distance adjustment mechanism for interpupillary distance adjustment. [0003] In the prior art, the distance adjustment mechanism generally adopts a screw nut mechanism or a rack and pinion mechanism. Or when the gear rotates in the clockwise direction, the movement of a functional component to one direction (can be called the positive direction) is realized. When the screw or the gear is rotated in the counterclockwise direction, the functional component can be realized in the ...

Problems solved by technology

[0004] The actual experience found that the above-mentioned adjustment method will bring a lot of inconvenience to the user: in the initial stage of adjusting the distance between the functional components, the user cannot pre-judge whether turning the screw or gear clockwise or counterclockwise can make the corresponding function The part moves in the desired direction, but the user needs to try to rotate to know the correct direction of rotation, resulting in a very high chance of misoperation; if the nut is already at the limit position of the screw (ie, the end of the screw), or the gear Already located at the limit position of the rack (that is, the end of the rack), the user needs to perform the aforementioned trial operation without knowing it, so once the user misoperates and exerts a lot of force, it is very likely to cause distance adjustment. The damage of the mechanism makes the distance adjustment mechanism have a greater probability of damage
