For a person of ordinary skill in the art, the specific meaning of the above terms in the present disclosure should be understood according to specific practice. 
     The technical concept of the present disclosure is as follows. The top binding band of the head-mounted apparatus is divided into two parts: a connection binding band provided with a connection wire, and an elastic adjustable binding band below the connection binding band. The connection binding band is used to realize the electrical connection of a front-end member and a rear-end member of a head-mounted apparatus, and the elasticity of the adjustable binding band is used to make the adjustable binding band contact and fit the top of the head of a user, thereby supporting and fixing the head-mounted apparatus, thus making the wearing of the head-mounted apparatus more comfortable and convenient. Moreover, the adjustable binding band is located below and firstly contacts the user&#39;s head to realize an elastic support, which also prevents the connection binding band, with a fixed length and provided with a connection wire, from being pulled, thereby ensuring the safety and reliability of the electrical connection. 
       FIG. 1  and  FIG. 2  show a top binding band according to an embodiment of the present disclosure. As shown in  FIG. 1  and  FIG. 2 , a top binding band is used to run across the top of the user&#39;s head to connect and fix the head-mounted apparatus. The top binding band comprises: a connection binding band  100  provided with a connection wire, and an adjustable binding band  200  below the connection binding band  100 . The connection binding band  100  electrically connects a front-end member and a rear-end member of the head-mounted apparatus with the connection wire, thereby realizing the circuit conduction between the front-end member and the rear-end member. The adjustable binding band  200  is made of an elastic material, and contacts and fits the top of the user&#39;s head by its elasticity to support and fix the head-mounted apparatus. The adjustable binding band  200  made of an elastic material can automatically adapt to different head shapes and sizes of users, and adjust its shape and length freely, thereby improving the user&#39;s wearing comfort of the head-mounted apparatus. 
     By using the double-layer structured top binding band comprising the connection binding band  100  and the adjustable binding band  200  according to the present disclosure, not only the electrical connection between the front-end member and the rear-end member of the head-mounted apparatus can be realized, but also the top binding band can adapt to the shapes and sizes of the head of users and automatically adjust its shape and size, thereby improving the wearing comfort of users. The adjustable binding band  200  is located below the connection binding band  100 , and in its natural state, the length of the adjustable binding band  200  is less than the length of the connection binding band  100 , so the adjustable binding band  200  contacts the user&#39;s head first, which prevents the connection binding band  100 , with a fixed length and provided with a connection wire, from being pulled, thereby ensuring the safety and reliability of the electrical connection. 
     In some embodiments of the present disclosure, the adjustable binding band  200  and the connection binding band  100  are assembled together by a detachable connection structure. Therefore, when one of the adjustable binding band  200  and the connection binding band  100  is damaged, it can be easily replaced and repaired, which reduces the maintenance cost of the top binding band. 
     As shown in the enlarged view of  FIG. 2 , the detachable connection structure between the adjustable binding band  200  and the connection binding band  100  comprises: fixing pins  110  provided at two ends of the connection binding band  100 , and buckles  210  provided at two ends of the adjustable binding band  200 . Under the action of elastic expansion and contraction of the adjustable binding band  200 , the buckle  210  can be sleeved on the fixing pin  110 , so that the adjustable binding band  200  and the connection binding band  100  are assembled together. 
       FIG. 3  is a schematic diagram of the top binding band according to another embodiment of the present disclosure, which shows another detachable connection structure. 
     As shown in  FIG. 3 , the detachable connection structure between the adjustable binding band  200  and the connection binding band  100  comprises connection holes  230  provided at two ends of the adjustable binding band  200 , and two ends of the connection binding band  100  can be inserted into the connection holes  230 , so that the adjustable binding band  200  and the connection binding band  100  are assembled together. In  FIG. 3 , the connection holes  230  are provided on the outer side of the adjustable binding band  200 , and two ends of the connection binding band  100  are provided in a plug shape corresponding to the connection holes  230 . The two ends of the connection binding band  100  are inserted from the upper ends of the connection holes  230  and go out from the lower ends of the connection holes  230 , thereby exposing the terminals of the connection wire and electrically connecting them to the front and the rear members of the head-mounted apparatus. 
     In some embodiments of the present disclosure, the connection binding band  100  adopts a silicone embedding structure, and the connection wire is embedded inside or on the surface of the silicone of the connection binding band  100 . 
     In some embodiments of the present disclosure, the adjustable binding band  200  is made of silicone, which has a good elasticity and softness, thus fits the top of the user&#39;s head well and makes wearing more comfortable. 
     In some embodiments of the present disclosure, two ends of the connection wire are respectively exposed from the two ends of the connection binding band  100 , and are provided with connectors, such as insertable plug, so that they can be easily electrically connected to the front and the rear members of the head-mounted apparatus. 
     In some embodiments of the present disclosure, two ends of the top binding band are provided with retaining rings, for example, retaining rings  120  provided at two ends of the connection binding band  100  as shown in  FIG. 2 , or retaining rings  220  provided at two ends of the adjustable binding band  200  as shown in  FIG. 3 . The top binding band is stuck with the housing of the front-end member and the rear-end member of the head-mounted apparatus by the retaining rings, as shown in the embodiment of the head-mounted apparatus shown in  FIG. 4 . The retaining rings make the top binding band stuck with the front-end member and the rear-end member of the head-mounted apparatus to ensure that the top binding band is firmly connected, and a dustproof effect is also provided. 
     The present disclosure also discloses a head-mounted apparatus.  FIG. 4  shows a schematic diagram of a head-mounted apparatus according to an embodiment of the present disclosure. As shown in  FIG. 4 , a top binding band as shown in any of the above embodiments is provided between a front-end member and a rear-end member of the head-mounted apparatus, and side binding band  500  are also provided between the front-end member and the rear-end member of the head-mounted apparatus. 
     As shown in  FIG. 4 , by installing and using the top binding bands disclosed in the above embodiments of the present disclosure, a safe and reliable electrical connection between the front-end member and the rear-end member of the head-mounted apparatus can be realized by the connection binding band  100 . Since the connection binding band  100  is provided with a connection wire, its length is fixed and it cannot be pulled at will. Under such a situation, due to the elastic effect of the adjustable binding band  200 , when the head-mounted apparatus is worn, the length of the adjustable binding band  200  will increase and thus a pulling force is generated, which has a lifting effect on the head-mounted apparatus and thus supports the weight of the head-mounted apparatus. Moreover, the elastic adjustable binding band  200  can adapt to the shapes and sizes of the head of users, thereby improving the wearing comfort. In the present disclosure, the wiring adapts a top-running form with the top binding band, and there is no need to provide an internal cavity in the side binding band  500  for wiring, thus the problems of high cost and stability risks caused by providing FPC wiring in the internal cavity can be avoided, and the problems of appearance and portability caused by providing the internal cavity in the side binding band  500 , making the structure incompact, can also be avoided. 
     In some embodiments of the present disclosure, as shown in  FIG. 4 , the side binding band  500  is made of a flexible material, such as a nylon weaving binding band, which fits the face better and more comfortably. Since there is no need to manufacture a hard plastic structure with an internal cavity, the manufacturing cost of the side binding band  500  is reduced. 
     In some embodiments of the present disclosure, the side binding band  500  is provided as a binding band passing through the rear-end member, or as two binding bands on left and right respectively connected between the front-end member and the rear-end member. 
     In some embodiments of the present disclosure, as shown in  FIG. 4 , the front-end member of the head-mounted apparatus is a front host  300 , and the rear-end member of the head-mounted apparatus is a battery box  400 . If the battery box  400  is removed from the virtual reality all-in-one machine, which has a processor and can independently provide virtual reality images, and placed on the back of the head, the front and rear weights of the head-mounted apparatus can be effectively balanced, thereby reducing the pressure applied on the user&#39;s face and improving the wearing comfort. 
     The above merely describes particular embodiments of the present disclosure. By the teaching of the present disclosure, a person skilled in the art can make other modifications or variations based on the above embodiments. A person skilled in the art should appreciate that, the detailed description above is only for the purpose of better explaining the present disclosure, and the protection scope of the present disclosure should be subject to the protection scope of the claims.
