下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种伸缩结构，该伸缩结构设置在虚拟现实头盔的头盔主体内，该伸缩结构可以调节虚拟现实头盔的大小，以使虚拟现实头盔适用于不同头部大小的用户。由于上述伸缩结构的具体实现存在多种方式，下面通过实施例进行详细说明：
请参见图1至图5所示，图1所示的为本发明实施例公开的一种伸缩结构的***图，图2和图3所示的为本发明实施例公开的一种伸缩结构的底部示意图，图4所示的为本发明实施例公开的伸缩板103的示意图，图5所示的为本发明实施例公开的底壳101和弹片102的示意图。
在图1至图5所示的实施例中，本发明实施例提供的伸缩结构设置在虚拟现实头盔的头盔主体内，伸缩结构包括设置有滑道的底壳101、弹片102和伸缩板103。
其中，弹片102的一端与底壳101相连接，弹片102的另一端上设置有压板106和第一限位部107。
伸缩板103上设置有与第一限位部107相适配的第二限位部108，伸缩板103的一端与虚拟现实头盔的头部固定装置相连接。
在压板106未受到外界作用力时，第一限位部107与第二限位部108相适配，以阻止伸缩板103在底壳101的滑道上滑动。
在压板106受到外界作用力时，弹片102发生弹性形变，第一限位部107与第二限位部108分离，伸缩板103可在底壳101的滑道上滑动。
在图1至图5所示的实施例中，在用户不需要改变虚拟现实头盔的大小时，用户便不会向压板106施加外界作用力，第一限位部107与第二限位部108会阻止伸缩板103在底壳101的滑道上滑动。在用户需要改变虚拟现实头盔的大小时，用户便会向压板106施加外界作用力，此时，弹片102发生弹性形变，以使第一限位部107与第二限位部108分离，伸缩板103便可在底壳101的滑道上滑动，从而增加或减少头盔主体与头部固定装置之间的长度，用户便可以将虚拟现实头盔调节至合适的大小，所以本发明提供的虚拟现实头盔可以适用于不同的人群。
在图1至图5所示的实施例中，伸缩结构还可以包括回弹部104和弹簧105。其中，回弹部104设置在底壳101上，弹簧105的一端与回弹部104连接，弹簧105的另一端与弹片102的另一端相连接。这样做的目的是，在压板106未受到外界作用力时，弹簧105未发生弹性形变；在压板106受到外界作用力时，弹簧105发生弹性形变，以产生反向作用力推动压板106回复至初始状态，所以回弹部104和弹簧105可以帮助压板106在外界作用力消失后更好的回复至初始状态。
在图1至图5所示的实施例中，第一限位部107为一个限位块，第二限位部108为多个与限位块相适配的限位槽。但是，第一限位部107与第二限位部108存在多种结构来形成摩擦力。
第一种可选的方案，第一限位部107为一个限位槽，第二限位部108为多个与限位槽相适配的限位块。
第二种可选的方案，第二限位部108为一个限位块，第一限位部107为多个与限位块相适配的限位槽。
第三种可选的方案，第二限位部108为一个限位槽，第一限位部107为多个
与限位槽相适配的限位块。
第四种可选的方案，第一限位部107为多个限位块，第二限位部108为多个与限位块相适配的限位槽。
第五种可选的方案，第一限位部107为多个限位槽，第二限位部108为多个与限位槽相适配的限位块。
在图1至图5所示的实施例中，第一限位部107可以为设置有第一斜面的限位块，第二限位部108为设置有第二斜面的限位槽，限位块的第一斜面与限位槽的第二斜面相接触；在伸缩板103与弹片102受到的外界作用力大于限位块的第一斜面与限位槽的第二斜面产生的摩擦力时，伸缩板103可在底壳101的滑道上滑动。这样做的目的是，在伸缩板103与弹片102受到的外界作用力大于限位块的第一斜面与限位槽的第二斜面产生的摩擦力时，即使用户未按压压板106，也可以实现伸缩板103在底壳101的滑道上滑动。当然，由于限位块和限位槽均只有一个斜面，所以在压板106未受到外界作用力的情况下，伸缩板103只能在底壳101的滑道上沿着一个方向滑动，而不能向相反的方向滑动。
请参见图6和图7所示，图6所示的为本发明实施例公开的一种虚拟现实头盔的示意图，图7所示的为本发明实施例公开的头盔主体200和伸缩结构的示意图。
在图6和图7所示的实施例中，本发明实施例提供的虚拟现实头盔包括头部固定装置300和头盔主体200，头盔主体200内设置有伸缩结构，伸缩结构包括设置有滑道的底壳101、弹片102和伸缩板103。
