Embodiment 1

[0039] Depend on Figure 1 to Figure 10Commonly shown, this embodiment discloses a strap adjustment device; it includes a casing 1, a strap adjustment gear 2 is installed in rotation in the casing 1, and a circular groove 13 is provided on the casing 1, and a circular groove 13 is installed in the circular groove 13. A one-way anti-rotation structure 3 is provided, and a push-type clutch mechanism 4 that cooperates with the one-way anti-rotation structure 3 to limit the rotation direction of the strap adjustment gear 2 is installed in the installation circular groove 13 . Wherein, the push-type clutch mechanism 4 includes an adjustment seat 41 that is rotatably installed in the installation circular groove 13 and connected with the strap adjustment gear 2, a self-resetting slider structure 42 that is radially slidably installed in the adjustment seat 41, and is arranged on the adjustment seat. The pressing drive structure 43 on 41, the end of the self-resetting slider structur...

Embodiment 2

[0055] Depend on figure 1 As shown, this embodiment discloses a rear strap, which includes a left strap 5, a right strap 6, and the rear strap adjustment device disclosed in the first embodiment; the second housing 12 is provided with a strap slide, The left strap 5 and the right strap 6 are respectively inserted from both ends of the strap slideway and are engaged with the strap adjustment gear 2 for transmission; the rotating strap adjustment gear 2 can make the left strap 5 and the right strap 6 move relative to each other back exercise.

Embodiment 3

[0057] This embodiment discloses a head-mounted display device, including a head-mounted main unit and the rear strap disclosed in the second embodiment above. Fixed connection.

[0058] The following is a brief description of the working process of the rear strap adjustment device based on the application of the rear strap including the rear strap adjustment device on the head-mounted display device:

[0059] Make a wide range of rough adjustments to the rear strap before wearing: press the drive structure 43, use the inclined surface to cooperate with the push principle, the pressure block 4321 on the pressure plate 432 drives the self-resetting slider structure 42 to slide radially towards the center, and the pawl ratchets The tooth structure 4211 is disengaged from the one-way anti-rotation structure 3 instantly. At this time, the strap adjustment gear 2 can rotate in both directions. By pushing and pulling the head-mounted main unit or rotating the adjustment seat 41, the...

Abstract

The invention discloses a rear bandage adjusting device, a rear bandage and head-mounted display equipment. The rear bandage adjusting device comprises a shell and a bandage adjusting gear; a one-wayrotation stopping structure and a pressing type clutch mechanism are arranged in an installation circular groove in the shell; and the pressing type clutch mechanism comprises an adjusting base rotationally installed in the installation circular groove and connected with the bandage adjusting gear, a self-resetting sliding block structure installed in the adjusting base in a radial sliding mode and a pressing driving structure arranged on the adjusting base, and the end, stretching out of the adjusting base, of the self-resetting sliding block structure is meshed with the one-way rotation stopping structure. The rear bandage comprises the rear bandage adjusting device, a left bandage body and a right bandage body. The head-mounted display equipment comprises the rear bandage and a head-mounted host. When the pressing driving structure is not pressed, only the adjusting base can be rotated unidirectionally to drive the bandage adjusting gear to rotate; and when the pressing driving structure is pressed, the self-resetting sliding block structure slides in the radial direction to be separated from the one-way rotation stopping structure, and the bandage adjusting gear can rotate in two directions. The rear bandage adjusting device, the rear bandage and the head-mounted display equipment are easy to assemble, high in reliability and low in noise during use.

Description

technical field [0001] The invention belongs to the technical field of head-mounted devices, and in particular relates to a rear strap adjustment device, a rear strap and a head-mounted display device. Background technique [0002] At present, VR games are in a period of rapid growth. As a head-mounted device, the wearing comfort has a crucial impact on the user experience. At present, the VR headsets on the market generally adopt the elastic arm ratchet structure (including the anti-rotation wheel, the support arm arranged on the wheel cylindrical surface of the anti-rotation wheel and the elastic arm connected with the support arm, and the end of the elastic arm is provided with a coupling ratchet) to adjust the strap; the disadvantage of the elastic arm ratchet structure is that when the strap is removed, the elastic arm is always stressed, resulting in particularly loud noise when the strap is released; and the elastic arm is prone to deformation or breakage, Poor relia...
