The invention relates to a head-mounted display device, and more particularly to a head-mounted display device with a wearable portion having an adjustable headband length and capable of preventing the headband from loosening.

In order to allow users of different body shapes to wear head-mounted display devices comfortably, general head-mounted display devices are often provided with upper straps and side straps of adjustable length. For example, an augmented reality head-mounted display device disclosed in Taiwan Utility Model Patent Certificate No. M630629 includes an augmented reality display, a back head pad, and an upper strap and a side strap connected between the augmented reality display and the back head pad. In order to adjust the length of the upper strap and the side strap, the side strap is connected to an adjustment mechanism installed on the back head pad, so that the user can adjust the length of the side strap by rotating the adjustment mechanism installed on the back head pad. Velcro is provided at the front and rear ends of the upper strap, and the front and rear ends of the upper strap pass through the front buckle plate and the rear buckle plate respectively and are fixed by the Velcro. In this way, the length of the upper strap is adjusted by the Velcro that can be repeatedly pasted and torn to adjust the head size of different users. However, when the upper strap is pulled by external force, the Velcro is easily torn off due to insufficient bonding force, so that the upper strap is loosened from the forehead pad and the rear guide pad, thereby causing inconvenience to the user. In addition, the conventional Velcro design makes it difficult to adjust the length of the upper strap without taking off the head mounted display device. Therefore, if the user finds that the length of the upper strap needs to be fine-tuned after putting on the head mounted display device, the user needs to take off the head mounted display device.

As shown in the figure, the elastic adjustment clip 3 includes an extension housing 13 extending from the outer surface of the main housing 11 and an adjustment button 31 movably accommodated in the extension housing 13. The extension housing 13 extends from the outer surface of the main body 1 and is integrally formed with the main body 1 by injection molding. The extension housing 13 includes a base 131 extending from the outer surface of the main body 1 and an operating portion 135 extending upward from the base 131. One side of the extension housing 13 further includes a protective cover 132 covering the operating portion 135, and a receiving space for accommodating the adjustment button 31 is formed between the operating portion 135 and the protective cover 132. In this embodiment, the upper surface of the main housing 11, the rear end surface of the base 131, and the bottom end of the protective cover 132 jointly define a space 136. The headband 2 is provided with a starting end 2a connected and fixed to the display part 200 and an end 2b connected and fixed to the main body 1 of the wearable part 100. The user can select any point between the starting end 2a and the end 2b of the headband 2 as a clamping point 301 according to needs, and then fix the elastic adjustment clip 3 at the clamping point 301 to adjust the length of the headband 2 between the wearable part 100 and the display part 200. In order to facilitate the user to pull the headband 2, a horizontal distance is provided between the base 131 of the extension shell 13 and the terminal 2b of the headband 2, thereby forming an adjustment space 102 between the clamping point 301, the base 131 of the extension shell 13, and the terminal 2b of the headband 2 for the user to pull the headband 2.

Please refer to the fourth and fifth figures. In this preferred embodiment, the headband 2 has the function of electrically connecting the display part 200 and the wearable part 100. A wire structure (not shown) is provided inside the headband 2. The headband 2 is provided with a covering structure 21 for protecting the wire structure. The covering structure 21 is a flexible material such as rubber, silicone, etc. The headband 2 can be bent and attached to the top of the user's head according to the shape of the user's head. Since the friction force of rubber and silicone is relatively large, the friction resistance between the covering structure 21 and the top of the user's head can be increased to prevent the headband 2 from slipping. A groove 203 is formed on the top surface of the display housing 201, and a groove 111 is formed on the top surface of the main housing 11. The starting end 2a of the headband 2 is inserted into the groove 203 of the display housing 201, so that one end of the headband 2 is connected and fixed to the display unit 200 and electrically connected to the display module 202.

In this preferred embodiment, the elastic adjustment clip 3 includes the extension shell 13, a through slot 133 passing through the extension shell 13, a limiting member 134 arranged on the rear end surface of the operating portion 135 of the extension shell 13, the adjustment button 31 that can be movably arranged on the limiting member 134, and an elastic member 32 arranged between the limiting member 134 and the adjustment button 31 to elastically displace the adjustment button 31 along the through slot 133. The headband 2 passes through the through slot 133 and the adjustment button 31 is movably disposed at the clamping point 301 on the headband 2. Therefore, the elastic member 32 pushes the adjustment button 31 to clamp and press the clamping point 301, so that the headband 2 can be kept fixed. Since the material of the covering structure 21 of the headband 2 is rubber or silicone, the friction resistance between the adjustment button 31 and the covering structure 21 is increased to prevent the headband 2 with adjusted length from shifting. In this preferred embodiment, the base 131 is formed by extending upward from the top of the main housing 11 and the operating portion 135 is extended upward from the top of the base 131. The protective cover 132 is provided on one side of the operating portion 135 to accommodate the adjustment button 31. A vertical distance, i.e., the space 136, is formed between the main housing 11 and the protective cover 132, so that the user can pull the headband 2 from the adjustment space 102 to adjust the wearing space 101. The through slot 133 penetrates the operating portion 135 and further penetrates the protective cover 132. The protective cover 132 is in a U-shape and the through slot 133 penetrates to the bottom edge of the protective cover 132. The adjustment button 31 includes a button 313 extending out of the receiving space. Furthermore, the button 313 passes through the protection cover 132 along the through slot 133 to allow the user to adjust the position of the adjustment button 31 .

A limiting column 311 is disposed on the left and right sides of the adjustment button 31. The limiting column 311 is radially extended to form a limiting convex ring 312. The limiting column 311 is matched and combined with the limiting member 134 and can move up and down along the limiting member 134, and the limiting convex ring 312 can move up and down between the upper limiting sleeve 134a and the lower limiting sleeve 134b. The elastic member 32 is a compression spring and is sleeved on the limiting column 311, and the upper and lower ends of the elastic member 32 elastically support the upper limiting sleeve 134a of the limiting member 134 and the limiting convex ring 312 respectively.

Please refer to the second, third, ninth and tenth figures. In this preferred embodiment, the position of the clamping point 301 can be further defined as a gap between the adjustment button 31 and the through slot 133. The adjustment button 31 can correspond to the up and down displacement of the through slot 133 to change the size of the gap. One end of the headband 2 connected to the main body 1 passes through the gap and makes the adjustment button 31 correspond to the clamping point 301 of the headband 2. When it is implemented specifically, the user can push the button 313 upward with one hand, and the elastic member 32 drives the adjustment button 31 to be compressed along the force direction to expand the gap between the bottom end of the adjustment button 31 and the through slot 133. Then the user pulls the headband 2 outward from the adjustment space 102 with the other hand. At this time, the headband 2 can freely pass through the gap and adjust the wearing space 101 according to the user's head size. In this way, the user can adjust the length of the headband 2 while wearing the head-mounted display device 400, and the excessively long portion of the headband 2 can be bent and arranged in the adjustment space 102 (not shown). When the user releases the button 313, the elastic member 32 rebounds and returns to its original position in the direction of force, so that the limiting convex ring 312 is pressed downward against the lower limiting sleeve 134b and the adjusting button 31 is displaced downward. At this time, the gap between the bottom end of the adjusting button 31 and the through slot 133 is reduced, so that the adjusting button 31 presses against the clamping point 301 of the headband 2 to fix the headband 2. In a specific implementation, the adjusting button 31 can also be configured to be able to move forward and backward corresponding to the through slot 133 to change the size of the gap, and the arrangement directions of the elastic member 32, the limiting column 311, and the limiting member 134 must be changed to the front and rear directions. Alternatively, the adjustment button 31 can also be configured to be able to move left or right corresponding to the through slot 133 to change the size of the gap, and the arrangement directions of the elastic member 32, the limiting column 311, and the limiting member 134 must be changed to be arranged in the left or right direction. In this embodiment, the elastic adjustment clip 3 is arranged on the main body 1, and the elastic adjustment clip 3 includes the extension shell 13 and the adjustment button 31 arranged between the protective cover 132 and the operating part 135, and the elastic member 32 and the limiting member 134 that are combined with the adjustment button 31.

In summary, the present invention provides a head-mounted display device 400, comprising the wearing part 100 for wearing on the user's head and the display part 200 correspondingly arranged in front of the user's eyes. The wearing part 100 comprises the main body 1, the headband 2 whose two ends are respectively connected to the main body 1 and the display part 200, the extension shell 13 extending from the outer surface of the main body 1, and the elastic adjustment clip 3 arranged on the extension shell 13. The user can fix the elastic adjustment clip 3 to the clamping point 301 of the headband 2 according to needs to adjust the length of the headband 2 between the main body 1 and the display part 200. In order to facilitate the user to pull the headband 2, a horizontal distance is provided between the base 131 of the extension shell 13 and the terminal 2b of the headband 2, thereby forming the adjustment space 102 for the user to pull the headband 2. Therefore, by turning the adjustment button 31 and pulling the headband 2 with the adjustment space 102, the overall length of the headband 2 between the main body 1 and the display part 200 can be effectively adjusted and the size of the wearing space 101 can be changed.
