Problems solved by technology

[0005] The disadvantages of the strap-type locking mechanism are: (1) The distance of the rear head is uncontrollable and the degree of automation is low
(2) Due to the elasticity of the connecting belt, it cannot withstand large shaking
(3) The life of the connection belt is low, and the wearing comfort of the head is poor
[0006] The disadvantages of the rack-and-pinion locking mechanism are: (1) There is no elastic retraction range for the head-wearing distance, and the body feels poor
(2) There is no automatic return function during adjustment, which is inconvenient to adjust
(3) Due to the meshing gap, the intermittent impact of the rack and pinion leads to a reduction in service life

Embodiment 1

[0038] Such as figure 1 , image 3 , Figure 6 , Figure 8 Shown is one of the embodiments of the present invention, in this embodiment, a head-wearing elastic auxiliary locking mechanism is provided with a connecting belt 3, a rear shell 1 is arranged at the rear of the connecting belt 3, and a lock is arranged in the rear shell 1 Tightening module 4, the two ends of the connecting belt 3 are equipped with racks 2, the racks 2 are inserted into the rear shell 1 to engage with the locking module 4, and the elastic belt 7 is connected between the connecting belt 3 and the rear shell 1, and the locking mold When the group 4 locks the rack 2, the elastic band 7 prevents the rack 4-2 from loosening with the locking module 4, and when the locking module 4 releases the rack 2, the elastic band 7 drives the rack 2 to reset.

[0039] Resetting here means that the elastic belt 7 drives the rack 2 to move to the state where the elastic belt 7 is not stressed, neither tensioned nor co...

Embodiment 2

[0051] In this example, if Figure 10 As shown, the elastic band 7 is made of silica gel, and the two ends of the elastic band 7 are provided with connection terminals 7-2, and the connection terminals 7-2 are provided with a number of fixing holes, which are respectively fixed on the connection band 3 and the rear shell 1 by screws. In order to ensure the connection strength, it is advisable to design the connection terminal 7-2 thicker and wider.

[0052] Adopting such a design can save buckles and simplify the installation structure of the elastic belt 7 .

Abstract

The invention discloses a head-mounted elastic auxiliary locking mechanism, which is provided with a connecting band, wherein the rear part of the connecting band is provided with a rear shell, the rear shell is internally provided with a locking module, both ends of the connecting band are provided with a rack, the racks are inserted into the rear shell and meshed with the locking module, an elastic band is connected between the connecting band and the rear shell, the elastic band prevents meshing of the racks and the locking module from loosening when the locking module locks the racks, and the elastic band drives the racks to reset when the locking module unlocks the racks. In the invention, the connecting band is provided with the elastic band, and an elastic pulling force is provided among internal assemblies of the locking mechanism, so that a function of closely meshing and bounce preventing is realized on the one hand, and a function of automatic return is realized on the other hand.

Description

technical field [0001] The invention relates to a head-wearing elastic auxiliary locking mechanism, which is used for head-wearing equipment. Background technique [0002] At present, most of the rear head-mounted locking mechanisms of head-mounted virtual products adopt strap type or rack-and-pinion type. The strap-type locking mechanism is mainly composed of a loose buckle and a connecting strap. When working, first adjust the appropriate wearing distance by loosening the buckle, and then put the product in. The rack and pinion locking mechanism is mainly composed of a rack and a gear assembly. Through the meshing and self-locking of the rack and pinion, the controllable adjustment of the head wearing distance is realized. [0003] For example, a strap-type locking mechanism is disclosed in the Chinese utility model patent "Virtual Reality Helmet Wearing Device" (authorized publication number: CN204351143U). The helmet body 2 is provided with a front shrink band 4a and a...
