Embodiment 1

[0038] Depend on Figure 1 to Figure 4 Commonly shown, this embodiment discloses a headband adjustment device; it includes a housing 1, a left headband 2 and a right headband 3; The ends of 3 are respectively connected with adjusting racks, and two adjusting racks extend into the housing 1 from the left and right sides respectively and are engaged with the synchronous gear 15 for transmission; Wherein, the effect of the synchronous gear 15 is to synchronize the motion of the two adjustment racks, so that the left headband 2 and the right headband 3 move equidistantly. One of the adjustment racks is provided with a ratchet rack structure 41, and a one-way locking structure 6 is slidably installed on the housing 1. The headband adjustment device at least includes a locked state and an unlocked state, and slides to the locked position to enter the locked state. When the one-way locking structure 6 meshes with the ratchet rack structure 41 to realize one-way locking, that is, the...

Embodiment 2

[0054] The structure and principle of the second embodiment are basically the same as those of the first embodiment. The difference is that the one-way locking structure 6 in the first embodiment is used to directly lock the left adjustment rack 4 one-way. The direction locking structure 6 is used to directly perform one-way locking on the right adjusting rack 5; only the differences will be described in detail below.

[0055] Such as Figure 9 and Figure 10 Commonly shown, in this embodiment, a ratchet rack structure 41 is provided on the upper end (top) of the right adjustment rack 5 (the bottom is provided with a rack structure meshing with the synchronous gear 15), and the inclined plane of the same ratchet groove 42 is guaranteed The distance from the groove side wall to the right side fixed end of the right adjustment rack 5 (fixed with the right headband 3) is less than the distance from the plane groove side wall to the right side fixed end of the right adjustment ra...

Abstract

The invention discloses a head band adjusting device and head-mounted equipment. The head band adjusting device comprises a shell, a synchronous gear rotationally installed in the shell and two adjusting racks. At least part of the adjusting racks extend into the shell and are in meshing transmission with the synchronous gear. At least one adjusting rack is provided with a ratchet bar structure, and a one-way locking structure is installed on the shell in a sliding mode. The head band adjusting device at least comprises a locking state and an unlocking state. When sliding to a locking position and entering a locking state, the one-way locking structure is meshed with the ratchet bar structure to realize one-way locking; and when sliding away from the locking position and entering an unlocking state, the one-way locking structure is separated from the ratchet bar structure. The shell is further provided with an elastic reset structure, and the elastic reset structure is used for providing elastic reset force which at least enables the one-way locking structure to have the trend of moving towards the locking position. The head-mounted equipment comprises the head band adjusting device. The structure is simple, the occupied space is small, and development of head-mounted products towards miniaturization and light weight is facilitated.

Description

technical field [0001] The invention belongs to the technical field of head-mounted equipment, and in particular relates to a lightweight headband adjusting device and the head-mounted device. Background technique [0002] In recent years, with the advancement of technology, virtual reality (VR, Virtual Reality) and augmented reality (AR, Augmented Reality) technologies have gradually been accepted by users and the market, and have become another engine driving technological innovation and display technology innovation. [0003] In the existing technologies, VR and AR technologies are generally implemented on the basis of head-mounted devices. However, the existing head-mounted devices are high-tech products with a very high degree of integration. In addition to the comfort of wearing, the design should also pay attention to the weight and volume of the entire product. At present, products are developing in the direction of miniaturization and light weight, which brings new...
