第一方面，如图1和图2所示，本申请实施例提供一种头戴显示器1，该头戴显示器1包括头戴显示器主体11以及与头戴显示器主体11固定的第一磁性结构12，第一磁性结构12配置为被独立于头戴显示器1之外的第二磁性结构2吸引或者排斥，以使头戴显示器1受到向上的磁性力。
需要说明的是，第二磁性结构2独立于头戴显示器1之外是指：第二磁性结构2不属于头戴显示器1，且第二磁性结构2与头戴显示器1之间不存在连接关系。第一磁性结构12配置为被第二磁性结构2吸引或者排斥，以使头戴显示器1受到向上的磁性力是指：第一磁性结构12能够与第二磁性结构2保持一定的距离以及方位关系，以使得头戴显示器1在第一磁性结构12与第二磁性结构2之间的吸引或排斥作用下受到向上的磁性力。
本申请实施例提供的头戴显示器，如图1和图2所示，由于该头戴显示器1包括头戴显示器主体11以及与头戴显示器主体11固定的第一磁性结构12，第一磁性结构12配置为被独立于该头戴显示器1之外的第二磁性结构2吸引或者排斥，以使头戴显示器1受到向上的磁性力，因此在用户佩戴头戴显示器1时，可通过第一磁性结构12被第二磁性结构2吸引或者排斥，以使得头戴显示器1受到向上的磁性力，该磁性力可以部分或者完全抵消头戴显示器1的重力，从而能够减小头戴显示器1对用户头部产生的压力，进而能够提升头戴显示器1的佩戴舒适度。
在一些实施例中，如图1和图2所示，第一磁性结构12为永磁铁，此第一磁性结构12的结构简单，容易实现，且永磁铁可以长久保留磁性，一次投入，后期产生的维护成本较小。
在另一些实施例中，第一磁性结构12为电磁铁，电磁铁的磁性有无、方向、大小可以控制，便于第一磁性结构12的磁性力的调节，以使头戴显示器1受到的向上的磁性力能够完全抵消头戴显示器1的重力。
在一些实施例中，如图3所示，头戴显示器1还包括第一电流调节结构13，第一电流调节结构13配置为调节第一磁性结构12内的电流大小。这样，可以通过第一电流调节结构13调节第一磁性结构12内电流的大小，达到调节第一磁性结构12的磁性大小的目的，从而能够使头戴显示器1受到的向上的磁性力完全抵消头戴显示器1的重力。
第一电流调节结构13可以为串联于第一磁性结构12所处电流回路中的变阻器，也可以为与第一磁性结构12的供电电源连接的电压调节器，该电压调节器能够调节供电电源的输出电压，在此不做具体限定。
在一些实施例中，如图3所示，第一电流调节结构13为串联于第一磁性结构12所处电流回路中的变阻器。这样，可以通过调节变阻器的阻值，达到调节第一磁性结构12内的电流大小的目的，此第一电流调节结构13简单，容易实现。
在一些实施例中，如图3所示，头戴显示器1还包括串联于第一磁性结构12所处的电流回路中的第一控制开关14。这样，在头戴显示器1未处于使用状态时，可以通过第一控制开关14切断第一磁性结构12所处的电流回路，以使第一磁性结构12断电失去磁性，避免第一磁性结构12对头戴显示器1周围其他电磁性结构产生干扰。
如图1和图2所示，头戴显示器主体11包括主机111以及与该主机111连接的定位支架112，定位支架112配置为将主机111固定于用户头部，第一磁性结构12可以固定于主机111上，也可以固定于定位支架112上，在此不做具体限定。
在一些实施例中，如图1和图2所示，第一磁性结构12固定于主机111上。由于头戴显示器1的重量通常集中于主机111上，因此将第一磁性结构12固定于主机111上，能够使头戴显示器1受到的磁性力能够有效抵消头戴显示器1的重力。其中，第一磁性结构13可以固定于主机111的壳体外，也可以固定于主机111的壳体内，在此不做具体限定。在一些实施例中，第一磁性结构12固定于主机111的壳体外，且主机111的壳体包括磁场屏蔽层，该磁场屏蔽层能够阻止第一磁性结构12的磁性对主机111的壳体内的电器件产生干扰。
设置于主机111上的第一磁性结构12的数量可以为一个，也可以为多个，在此不做具体限定。
在一些实施例中，如图1所示，第一磁性结构12的数量为多个，多个第一磁性结构12沿主机111的宽度方向(也即是图1所示的方向X)间隔排列。这样，通过多个第一磁性结构12作用，能够增大头戴显示器1受到的磁性力，以使头戴显示器1受到的磁性力能够与头戴显示器1的重力完全抵消，且头戴显示器1受到的多个磁性力分散于主机111沿其宽度方向的多个位置，因此该磁性力能够平稳支撑主机111，提升头戴显示器1的佩戴舒适度。其中，第一磁性结构12的数量可以为2个、3个、4个或者5个等等，在此不做具体限定。示例的，如图1所示，第一磁性结构12的数量为3个。
在上述实施例中，需要说明的是，主机111的宽度方向是指当头戴显示器1佩戴于用户头部并处于使用状态时，主机111上与用户双眼排列方向相平行的方向。
第二方面，本申请实施例提供一种虚拟现实系统，该虚拟现实系统包括头戴显示器1和第二磁性结构2，头戴显示器1为如上任一实施例所述的头戴显示器1，第二磁性结构2配置为吸引或者排斥头戴显示器1的第一磁性结构12，以向该头戴显示器1施加向上的磁性力。
本申请实施例提供的虚拟现实系统，由于该虚拟现实系统包括头戴显示器1和第二磁性结构2，头戴显示器1为如上任一实施例所述的头戴显示器1，第二磁性结构2配置为吸引或者排斥头戴显示器1的第一磁性结构12，以向该头戴显示器1施加向上的磁性力，因此在用户佩戴头戴显示器1时，可通过第二磁性结构2吸引或者排斥头戴显示器1的第一磁性结构12，以向头戴显示器1施加向上的磁性力，该磁性力可以部分或者完全抵消头戴显示器1的重力，从而能够减小头戴显示器1对用户头部产生的压力，进而能够提升头戴显示器1的佩戴舒适度。
在一些实施例中，第二磁性结构2为永磁铁。此第二磁性结构2的结构简单，容易实现，且永磁铁可以长久保留磁性，一次投入，后期产生的维护成本较小。
在另一些实施例中，第二磁性结构2为电磁铁。电磁铁的磁性有无、方向、大小可以控制，便于第二磁性结构2的磁性力的调节，以使施加至头戴显示器1的磁性力能够完全抵消头戴显示器1的重力。
在一些实施例中，如图4所示，虚拟现实系统还包括第二电流调节结构6，该第二电流调节结构6配置为调节第二磁性结构2内的电流大小。这样，可以通过第二电流调节结构6调节第二磁性结构2内电流的大小，达到调节第二磁性结构2的磁性大小的目的，从而能够使施加至头戴显示器1的磁性力完全抵消头戴显示器1的重力。
第二电流调节结构6可以为串联于第二磁性结构2所处电流回路中的变阻器，也可以为与第二磁性结构2的供电电源连接的电压调节器，该电压调节器能够调节该供电电源的输出电压，在此不做具体限定。
在一些实施例中，如图4所示，第二电流调节结构6为串联于第二磁性结构2所处电流回路中的变阻器。这样，可以通过调节该变阻器的阻值，达到调节第二磁性结构2内的电流大小的目的，此第二电流调节结构6简单，容易实现。

为了使第二磁性结构2能够吸引或者排斥头戴显示器1的第一磁性结构12，以向该头戴显示器1施加向上的磁性力，头戴显示器1在使用时，第二磁性结构2与头戴显示器1之间需保持一定的方位关系。
在一些实施例中，如图5所示，虚拟现实系统还包括用于支撑座椅8的座椅支撑台3，第二磁性结构2设置于座椅支撑台3内，第二磁性结构2配置为排斥头戴显示器1的第一磁性结构12。这样，用户坐在座椅支撑台3上方的座椅8上，并佩戴头戴显示器1时，座椅支撑台3内的第二磁性结构2处于头戴显示器1的第一磁性结构12的下方，由于第二磁性结构2排斥头戴显示器1的第一磁性结构12，由此，第二磁性结构2能够与第一磁性结构12作用，以向头戴显示器1施加向上的磁性力。且由于座椅支撑台3内的空间较大，因此便于布置第二磁性结构2。
在一些实施例中，如图6所示，虚拟现实系统还包括颈枕4，第二磁性结构2设置于颈枕4内，第二磁性结构2配置为排斥头戴显示器1的第一磁性结构12。这样，用户在同时佩戴头戴显示器1和颈枕4时，颈枕4内的第二磁性结构2处于头戴显示器1的第一磁性结构12的下方，由于第二磁性结构2排斥头戴显示器1的第一磁性结构12，由此，第二磁性结构2能够与第一磁性结构12作用，以向头戴显示器1施加向上的磁性力。
在一些实施例中，如图7所示，虚拟现实系统还包括用于容纳座椅8的座椅机舱5，第二磁性结构2设置于座椅机舱5的顶部，第二磁性结构2配置为吸引头戴显示器1的第一磁性结构12。这样，用户佩戴头戴显示器1，并坐在座椅机舱5内的座椅8上时，座椅机舱5顶部的第二磁性结构2处于头戴显示器1的第一磁性结构12的上方，由于第二磁性结构2吸引头戴显示器1的第一磁性结构12，由此，第二磁性结构2能够与第一磁性结构12作用，以向头戴显示器1施加向上的磁性力。
