Electronic equipment and distance adjusting mechanism thereof

Abstract

The invention discloses a distance adjusting mechanism. The distance adjusting mechanism comprises a rotary wheel, a first part and a second part, and the first part is in eccentric connection with the first end face of the rotary wheel and is driven to conduct linear reciprocating motion when the rotary wheel rotates unidirectionally; the second part is in eccentric connection with the second endface of the rotary wheel and is driven to conduct linear reciprocating motion when the rotary wheel rotates unidirectionally, the motion tracks of the two parts are parallel to each other or coincidewith each other, and the first junction of the second part and the rotary wheel is staggered from the second junction of the second part and the rotary wheel. According to the distance adjusting mechanism, since the change of the distance between the first part and the second part is achieved through the unidirectional rotation of the rotary wheel, no matter which direction a user rotates the rotary wheel in, the purposes of increasing and reducing the distance can both be achieved, the misoperation phenomenon does not exist, and the limit position of the rotary adjustment mode does not existeither, so that the damage probability of the distance adjustment mechanism is also obviously lowered. The invention further provides electronic equipment provided with the 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
