Detailed ways

Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.

The orientations involved in this manual are all based on the orientation of the head-mounted display of the utility model when it is working normally, and are not limited to its orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

As shown in Fig. 1, Fig. 2 and Fig. 5 together, the head-mounted display includes a main body 1, and the main body 1 is placed and used right in front of the user's eyes for the user's visual experience. The main body 1 is connected with a headband 2, and the head The belt 2 is bound on the user's head, so as to realize the wearing of the main body 1 on the user's head. The main body 1 is hinged with a connecting component 3, and the connecting component 3 can be a fixing part, such as a connecting rod, for connecting the main body 1 and the support The plate 4 can also be an assembly with adjustable length. The connecting component 3 can swing at a certain angle relative to the main body 1. The connecting component 3 is equipped with a support plate 4 corresponding to the forehead and the top of the head of the user. The support plate 4 is used for To ensure that the user can firmly wear the main body 1, the main body 1 is equipped with an elastic element 5 that drives the connecting assembly 3 to swing toward the headband 2, and the elastic element 5 provides a continuous elastic force for the connecting assembly 3, so that the connecting assembly 3 swings. The swinging support plate 4 of the component 3 will be pressed against the forehead and the top of the head of the user, so as to ensure that the distance between the support plate 4 and the main body 1 has an adjustable range, so as to meet the wearing and use of different users, especially the The distance between the eyes and the forehead is different for different users, which improves the wearing comfort of the user. The elastic element 5 can be a torsion spring or a compression spring to provide an elastic thrust, or it can be a tension spring. In order to provide elastic tension, other elements that can continuously provide elastic force can also achieve this effect. In this embodiment, a torsion spring is preferred. The direction of the elastic force provided by the torsion spring is always consistent with the direction of rotation of the connecting assembly 3, and the elastic force provided is more uniform. .

As shown in Figure 5, the connection assembly 3 in this embodiment includes a first connection plate 30, one end of the first connection plate 30 is connected to one side of the support plate 4, and a sliding groove 31 is provided in the first connection plate 30, and the sliding Groove 31 is positioned at the side of first connecting plate 30 that is not connected to support plate 4, and chute 31 is arranged along the lengthwise direction of first connecting plate 30, and second connecting plate 32 is inserted and connected in chute 31, and the second connecting plate 32 is hingedly installed on the main body 1 toward one end of the main body 1, and the inner wall of the chute 31 is provided with a plurality of fixedly spaced limiting grooves 33 along the insertion direction of the second connecting plate 32, and the second connecting plate 32 is installed with The limit block 34 snapped into the limit groove 33 can make the second connection plate 32 slide in the chute 31 by pulling the second connection plate 32, so as to adjust the length of the connection assembly 3. The connection assembly 3 is in different positions. When the length is longer, the limit block 34 will be fixed in different limit grooves 33 to ensure that the connecting assembly 3 can maintain the distance after the length adjustment. The limit block 34 slides from a limit groove 33 with the second connecting plate 32 The process of coming out and entering into another adjacent limiting groove 33 is realized by the deformation of the limiting block 34 and the slide groove 31 when they are pressed against each other.

As shown in Figure 5, an inclined surface 35 is respectively provided between the front and rear side walls of the limit block 34 along the insertion direction of the second connecting plate and the upper end surface of the limit block 34, and the limit block 34 is arranged along the second connecting plate. The part between the front and rear side walls of the plate insertion direction and the upper end surface of the limit block 34 is the part where the limit block 34 directly presses against the inner wall of the chute 31 and the groove wall of the limit groove 33, and the inclined surface 35 can be The smoothness of the sliding adjustment of the second connecting plate 32 in the sliding groove 31 is ensured, and the blocking of the limiting block 34 in the limiting groove 33 is avoided.

As shown in Figure 5, this embodiment provides a hinged embodiment of the connection assembly 3 and the main body 1, wherein the main body 1 is equipped with a fixed plate 10, and the fixed plate 10 is provided with a support block 101, which is rotatably connected There is a horizontally arranged rotating shaft 321, two supporting blocks 101 are provided, the two ends of the rotating shaft 321 are respectively connected on the two supporting blocks 101, and the second connecting plate 32 is fixedly connected with the rotating shaft 321, so that the rotation of the rotating shaft 321 will realize the connection of the connecting assembly 3. In the overall swing, the spring section of the torsion spring is sleeved on the rotating shaft 321 , and the two supporting ends of the torsion spring elastically press against the fixing plate 10 and the second connecting plate 32 respectively.

As shown in Figure 3 and Figure 4, the swing angle range of the connecting assembly 3 is 0°~75°, and the angle range can be realized by installing a limiting component on the main body 1. Under the action of no external force, only the elastic element 5. The connecting component 3 driven by 5 will be in the lower limit swing position, that is, the 0° position. At this time, the connecting component 3 is close to the headband 2, which ensures that the head-mounted display can reduce the occupied space as much as possible when it is idle, and is easy to carry As well as transportation, the upper limit swing angle of the connection assembly 3 is 75°, which can ensure that the connection assembly 3 has a sufficient adjustment range, and does not make the connection assembly 3 swing up too large so that the support plate 4 loses its functional effect.

As shown in FIG. 5 , the end of the second connecting plate 32 close to the rotating shaft 321 is provided with a limiting plate 320 , and the limiting plate 320 is pressed against the fixing plate 10 as the connecting assembly 3 swings up, so as to realize the upward movement of the connecting assembly 3 . The limit of the pendulum, that is, when the connecting assembly 3 swings up to a position of 75°, the limiting plate 320 will press against the fixing plate 10 to prevent the connecting assembly 3 from further swinging up.

As shown in Figure 5, the middle section of the second connecting plate 32 is pressed against the upper edge of the front side of the main body 1 along with the hem of the connecting assembly 3, and the installation position of the rotating shaft 321 has a certain distance from the front side of the main body 1 in the horizontal direction. In this way, as the connection assembly 3 swings down, the second connection plate 32 will press against the main body 1 to form a limit, and at this time the connection assembly 3 is at the 0° position.

As shown in Figure 2, the headband 2 is a headband 2 with an adjustable binding range. The headband 2 can be an elastic soft belt, or a stretchable and adjustable fixed belt, or a combination of an elastic soft belt and a fixed belt. This satisfies the user's wearing comfort.

As shown in Figure 1, a soft pad 20 is installed on the inner side of the headband 2, and the soft pad 20 is arranged at the back of the head of the user. Since the support plate 4 will exert pressure on the user's forehead and the top of the head, the position of the back of the head of the user will be affected by the headband 2. The soft pad 20 will reduce the pressure feeling on the user's head and improve the wearing comfort.

The utility model is not limited to the above-mentioned specific implementation manners, and various transformations made by those skilled in the art starting from the above-mentioned ideas without creative work all fall within the protection scope of the utility model.
