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 diopter adjustment method. The transmission mechanism is used for controlling a first frame to move relative to a second frame, wherein the first frame is connected with the second frame through connecting components on the first frame; the transmission mechanism includes a shifting wheel with bevel gears, bevel gears, transmission shafts, transmission gears and cams; the shifting wheel with the bevel gears and the transmission shafts are installed on a horizontal frame of the second frame; the bevel gears are installed on the transmission shafts; the bevel gears are engaged with the bevel gears on the shifting wheel; the transmission gears, being in axial symmetry relative to the transmission shafts, are installed on vertical frames of the second frame; the cams are installed on the vertical frames of the second frame and are engaged with the transmission gears; the connecting components are provided with rollers; the cams are provided with sliding grooves; and the rollers are clamped into the sliding grooves and can move along the sliding grooves in a reciprocating manner, and can drive the connecting components to move linearly in a reciprocating manner. With the transmission mechanism provided by the above technical scheme of the invention adopted, direction-changing transmission and rotational-to-linear movement can be realized. The transmission mechanism has the advantages of stable and reliable transmission, simple structure and low cost.

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...
