As shown in fig. 1 to 6, in the present embodiment, a first sliding surface is disposed on an end surface of the connecting member 200 facing the adjusting member 300, the first sliding surface is a plane disposed obliquely, and in a sliding direction of the connecting member 200, the first sliding surface has an end close to the adjusting member 300 and an end far from the adjusting member 300, wherein the first adjusting position is disposed at an end close to the connecting member 200, and the second adjusting member 300 is disposed at an end far from the connecting member 200; in addition, the rotation axis of the adjusting member 300 passes through the center of the first sliding surface, because the driving portion 400 is disposed on the outer peripheral surface of the adjusting member 300 and extends along the radial direction of the adjusting member 300, the abutting position of the driving portion 400 and the first sliding surface deviates from the rotation axis of the adjusting member 300, such that, when the adjusting member 300 rotates, the abutting position of the driving portion 400 and the first sliding surface will perform a circular motion around the rotation axis of the adjusting member 300, and because the sliding surface is disposed obliquely, during the rotation of the driving portion 400, the abutting position of the driving portion 400 and the first sliding surface will move close to or away from the adjusting member 300 in the sliding direction of the connecting member 200, when the abutting position reaches the end of the first sliding surface close to the adjusting member 300, i.e. the first adjusting position, the abutting position of the connecting member 200 reaches the position away from the adjusting member 300 at this time under the action of the driving portion 400, the distance between the lens 20 and the display screen 10 is the largest, and when the abutting position reaches the first sliding surface reaches the first adjusting member 300, the abutting position of the second lens 20 and the second adjusting position is the second adjusting position, the distance between the lens 20 and the display screen is adjusted reciprocally in the direction according to the first circle, and the first circle distance between the two adjusting positions is adjusted; in addition, since the connecting piece 200 has a tendency to move close to the adjusting piece 300 under the action of the elastic piece 500, when the driving portion 400 rotates from the first adjusting position to the second adjusting position, due to the inclined arrangement of the first sliding surface, the first sliding surface is abutted against the driving portion 400 under the action of the elastic piece 500 and can give the driving portion 400 a force rotating towards the second adjusting position, so that the driving portion 400 can automatically move towards the second adjusting position under the driving of the force, and the position adjustment of the driving portion 400 in the first adjusting position to the second adjusting position is facilitated; in order to ensure the stability of the position of the driving part 400 at the first adjusting position and the second adjusting position, a damping structure may be disposed on the vision adjusting device 30, and when the driving part 400 rotates to the first adjusting position and the second adjusting position, the driving part 400 is limited to rotate continuously through the damping structure, so as to ensure the stability of the position of the driving part 400, for example, the damping structure may be a rubber ring sleeved on the outer side of the adjusting part 300, and the rubber ring may be fixedly connected with the housing 100 and rotate relative to the adjusting part 300, and the rubber ring and the adjusting part 300 may be in interference fit, so that the rubber ring may be tightly wrapped around the periphery of the adjusting part 300 after being elastically deformed, a certain friction force may be provided between the rubber ring and the adjusting part 300, and when the adjusting part 300 needs to rotate, the rotation of the adjusting part 300 may be realized only by overcoming the friction force, and when the external force is removed, the adjusting part 300 may be limited to rotate under the friction force of the rubber ring, so as to ensure the stability of the position of the driving part 400. Therefore, compared with the conventional gear-driven adjustment method, the adjustment method of the present invention can realize the increase and decrease of the distance between the lens 20 and the display screen 10 by only rotating the adjustment member 300 in one direction, and has the advantage of simple adjustment, and in addition, due to the inclined first sliding surface, the driving portion 400 is always in contact with the first sliding surface during rotation, and in the sliding process of the driving portion 400 relative to the first sliding surface, the first sliding surface is a continuous plane, so that the sliding of the driving portion 400 is smoother, the driving portion 400 is prevented from being blocked, and the operation feel and the reliability of the visibility adjustment device 30 are improved.

Further, the first sliding surface is provided with a first locking groove 240, and at least one of the first adjustment position and the second adjustment position is provided with the first locking groove 240.

Further, the first sliding surface is provided with a second locking groove 610, and the second locking groove 610 is provided between the first adjustment position and the second adjustment position along the sliding direction of the driving part 400.

Specifically, as shown in fig. 3, in order to improve the stability of the driving portion 400 when being matched with the first adjusting position and the second adjusting position, in this embodiment, the first sliding surface is further provided with a first locking groove 240, the first locking groove 240 is a groove structure that is opened towards one side of the adjusting member 300, the first locking groove 240 may be simultaneously disposed at the first adjusting position and the second adjusting position, or may be disposed at one of the first adjusting position and the second adjusting position, the shape of the first locking groove 240 is adapted to the shape of the end face of the driving portion 400 abutting against the first sliding surface, in this embodiment, the first locking groove 240 is in an arc groove structure, that is, the inner wall of the first locking groove 240 is an arc surface, the extending direction of the arc surface is a tangential direction of the rotation track of the driving portion 400 when the first arc surface abuts against the end face, and the arc surface extends along the tangential direction of the rotation track of the driving portion 400. Thus, when the driving part 400 rotates to the first locking groove 240 position, the connection member 200 moves close to the adjustment member 300 by the elastic member 500. The first locking groove 240 will also move close to the driving portion 400 until the end of the driving portion 400 is embedded into the first locking groove 240, and when the external force is removed, the restriction of the driving portion 400 in the first locking groove 240 will not continue to move, thereby realizing the positioning at the first locking groove 240. When the positioning needs to be released, only a force needs to be applied to the adjusting member 300, so that after the driving portion 400 slides out from the first locking groove 240, the driving portion 400 can continue to slide along the first sliding surface, and further, the visibility is continuously adjusted. In this technical scheme, through set up first locking groove 240 on first regulation position and second regulation position, realized the location of this drive portion 400 at first regulation position and second regulation position, in VR equipment use, spacing to drive portion 400 through this first locking groove 240 has also prevented that VR equipment from taking place the position variation and then leading to the visibility to change under the use scene such as rocking, is favorable to improving the use reliability and the user's of this visibility adjusting device 30 use experience.
