Embodiment Construction

[0035] The core idea of ​​the present invention is: in view of the problem of complex and costly diopter adjustment structures of head-mounted displays in the prior art, the transmission mechanism of the present invention can realize direction-changing transmission and rotation-changing linear motion, and the transmission is stable and reliable through gear transmission. , The self-locking is realized by using the cam mechanism with simple structure and easy to realize more complex motion rules, which ensures the simplicity and high efficiency of self-locking. And the cost of the solution of the present invention is low.

Abstract

The invention discloses a transmission mechanism, a head-mounted display and a refraction adjustment method thereof. The transmission mechanism is used to control the movement of the first frame relative to the second frame, and the first frame is connected to the second frame through a connecting piece thereon. , including: dial wheel with bevel gear, bevel gear, transmission shaft, transmission gear and cam; dial wheel and transmission shaft with bevel gear are installed on a horizontal frame of the second frame; bevel gear is installed on the transmission shaft, bevel The gear meshes with the bevel gear on the dial with bevel gear; the transmission gear is installed on the vertical frame of the second frame symmetrically with the transmission axis; the cam is installed on the vertical frame of the second frame and meshes with the transmission gear; the connecting piece Rollers are arranged on the cam, and sliding grooves are arranged on the cam. The rollers are inserted into the sliding grooves, and can reciprocate along the sliding grooves, and at the same time drive the connecting parts to perform linear reciprocating motions. The technical scheme of the present invention realizes direction-changing transmission and rotation-to-linear motion, and the transmission is stable and reliable, and the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a transmission mechanism, a head-mounted display and a refraction adjustment method thereof. Background technique [0002] Currently, the head-mounted displays on the market are not well-designed, have complex mechanisms, and are bulky. Moreover, head-mounted displays usually do not consider the needs of myopia users. Even if some head-mounted displays can achieve diopter adjustment, the refraction adjustment mechanism is particularly complicated and the cost is very high. In addition, the existing head-mounted displays are in When realizing diopter adjustment, it often does not have a self-locking function, or requires additional facilities to assist in realizing self-locking, which will also increase the cost of the diopter adjustment solution and severely limit the development of head-mounted displays. Contents of the invention [0003] The invention provides a transmissio...
