[0037] This application provides a head-mounted display device, which can be one of various interactive head-mounted display devices such as augmented reality (AR), virtual reality (VR), mixed reality (MR), and smart glasses.

[0038] Reference Figure 1 , Figure 2 and Figure 4 This application provides a head-mounted display device, which includes:

[0039] Headgear structure 1;

[0040] The main body of the device 2 is rotatably connected to the head-mounted structure 1 and has a display position and an avoidance position;

[0041] The drive structure 3 includes a hydraulic unit 31, a first drive member 32, and a second drive member 33. The hydraulic unit 31 forms a hydraulic cavity inside. The first drive member 32 is movably connected to the hydraulic unit 31 along a first direction and can extend into the hydraulic cavity. The second drive member 33 is movably connected to the hydraulic unit 31 along a second direction and can extend into the hydraulic cavity. The second direction intersects with the first direction.

[0042] When the first driving member 32 compresses the hydraulic chamber along the first direction, the second driving member 33 moves along the second direction and can push the main body 2 of the device to switch from the display position to the avoidance position.

[0043] In this embodiment, the head-mounted structure 1 can be the temple of smart glasses, or the head-mounted structure 1 can be a U-shaped rear head-mounted structure in a head-mounted device, both of which facilitate the wearing of the head-mounted display device on the user's head.

[0044] When the head-mounted display device is worn, the main body 2 of the device has a display position and an avoidance position. When the main body 2 of the device is in the display position, the main body 2 of the device is facing the user's eyes, and the user can view the image on the main body 2 to realize the interactive experience of the head-mounted display device.

[0045] When the device body 2 is in the avoidance position, meaning it needs to avoid the user's eyes so that the user's eyes are exposed, the user can perform visual operations, such as answering phone calls, browsing notifications, or making visual observations. Since the first driving member 32 is movably connected to the hydraulic unit 31 along the first direction and can extend into the hydraulic chamber, when the first driving member 32 compresses the hydraulic chamber along the first direction, for example, by pressing the first driving member 32 along the first direction, the pressure of the liquid in the hydraulic chamber increases. The increased pressure of the liquid will push the second driving member 33 to move towards the device body 2 along the second direction, thereby pushing the device body 2 to flip from the display position to the avoidance position.

[0046] The second direction can be perpendicular to the first direction, or it can be at an angle of less than 90° to the first direction, such as 30°, 45°, 60° or 75°. Alternatively, the second direction can be at an angle of greater than 90° to the first direction, such as 120°, 135°, 150° or 165°.

[0047] The rotation angle of the main body 2 from the display position to the avoidance position can be 30°, 45°, 60°, 75°, 90°, 120° or 150°, which can be determined according to the force of the user pressing the first driving component 32 and the degree of eye strain.

[0048] The main body 2 of the device can be exposed to the user's eyes when in an avoidance position, enabling the user to operate with their eyes without having to remove the entire head-mounted display device. This simplifies operation, ensures the stability of the head-mounted display device, and improves user satisfaction and convenience.

[0049] In one embodiment, both ends of the device body 2 are rotatably connected to the head-mounted structure 1, so that both ends of the device body 2 can be driven to rotate simultaneously by the drive structure 3, thereby improving the stability and efficiency of the rotation of the device body 2.

[0050] In one embodiment, the hydraulic unit 31 can be fixed to the headgear structure 1 to ensure the stability of the drive structure 3 during the movement of the first drive member 32 and the second drive member 33 relative to the hydraulic unit 31.

[0051] The head-mounted display device provided in this application includes a head-mounted structure 1, a device body 2, and a drive structure 3. The device body 2 is rotatably connected to the head-mounted structure 1 and has a display position and an avoidance position. The drive structure 3 includes a hydraulic unit 31, a first drive member 32, and a second drive member 33. A hydraulic cavity is formed inside the hydraulic unit 31. The first drive member 32 is movably connected to the hydraulic unit 31 along a first direction and can extend into the hydraulic cavity. The second drive member 33 is movably connected to the hydraulic unit 31 along a second direction and can extend into the hydraulic cavity. The second direction intersects with the first direction. When the first drive member 32 compresses the hydraulic cavity along the first direction, the second drive member 33 moves along the second direction and can push the device body 2 from the display position to the avoidance position. The user's eyes can be exposed without removing the entire head-mounted display device. The operation is simple, and the stability of wearing the head-mounted display device is ensured.

[0052] In one embodiment, the first direction is the vertical direction of the head-mounted display device, and the second direction is the front-back direction of the head-mounted display device. That is, the second direction is perpendicular to the first direction. While ensuring that the driving structure 3 drives the steering, the device body 2 can be flexibly rotated from the display position to the avoidance position.

[0053] In one specific embodiment, the first direction is Figure 4 The Y direction in the equation includes (+Y and -Y directions), and the second direction is... Figure 4 The X direction in the equation includes both the +X direction and the -X direction.

[0054] like Figure 4 As shown, pressing the first drive member 32 downward along the -Y direction causes the first drive member 32 to gradually extend into the hydraulic chamber and compress the liquid in the hydraulic chamber. The pressure of the liquid in the hydraulic chamber increases, and the increased pressure of the liquid will push the second drive member 33 to move towards the main body 2 of the device along the +X direction, so that the main body 2 of the device can be moved away from the user's eyes and achieve the purpose of avoiding the position.

[0055] In one embodiment, see Figure 2 and Figure 4 The first driving member 32 includes a first active end 321 and a first driven end 322. The first active end 321 is located outside the head-mounted structure 1, and the first driven end 322 is located in the hydraulic cavity. The second driving member 33 includes a second active end 331 and a second driven end 332. The second active end 331 is located in the hydraulic cavity, and the second driven end 332 faces the display position of the device body 2.

[0056] When the first active end 321 is in a pressed state, the second passive end 332 pushes the main body 2 of the device to switch from the display position to the avoidance position.

[0057] In this embodiment, the first active end 321 is located outside the head-mounted structure 1, which facilitates the user's pressing operation of the first active end 321; the first driven end 322 extends into the hydraulic cavity, and the second active end 331 also extends into the hydraulic cavity. When the first active end 321 is pressed and the first driven end 322 gradually extends into the hydraulic cavity, the pressure of the liquid in the hydraulic cavity increases, which will push the second active end 331 to move. The second active end 331 then drives the second driven end 332 to move towards the device body 2, so that the second driven end 332 can push the device body 2 to flip upward from the display position; by maintaining the pressing of the first active end 321, the device body 2 can be flipped to the avoidance position, which is convenient for the user to perform eye operations after exposing their eyes while wearing the head-mounted display device.

[0058] In one embodiment, see Figure 4 and Figure 5 The drive structure 3 includes an elastic reset member 34, one end of which is connected to the first active end 321, and the other end of which is connected to the head-mounted structure 1.

[0059] In this embodiment, when the first active end 321 is in a pressing operation, the distance between the first active end 321 and the head-mounted structure 1 gradually decreases. Since the elastic reset member 34 is connected between the first active end 321 and the head-mounted structure 1, the elastic reset member 34 will generate elastic deformation when the first active end 321 is pressed. After the first active end 321 is released from the pressing, the device body 2 has a tendency to reset from the avoidance position to the display position. The elastic deformation of the elastic reset member 34 can slow down the reset speed of the device body 2, avoid hard collision between the device body 2 and the head-mounted structure 1, and ensure the structural integrity of the device body 2.

[0060] In a specific embodiment, such as Figure 4 As shown, the first active end 321 has a pressure plate 323, and one end of the elastic reset member 34 is connected to the pressure plate 323. The pressure plate 323 can increase the pressing area, which facilitates the pressing operation of the first active end 321. By pressing the pressure plate 323, the first driving member 32 is squeezed. Under the action of the liquid pressure in the hydraulic chamber, the second driving member 33 gradually extends out of the hydraulic chamber, thereby pushing the main body 2 of the device to rotate, which can quickly achieve the effect of switching the field of vision for the eyes.

[0061] In one embodiment, see Figure 1 and Figure 5 The head-mounted structure 1 is provided with a slide rail 13. The elastic reset member 34 includes an elastic rod 341 and an elastic sheet 342. One end of the elastic rod 341 is connected to the first active end 321, and the other end of the elastic rod 341 is provided with a slider 3411. The slider 3411 slides in cooperation with the slide rail 13. One end of the elastic sheet 342 is connected to the slider 3411, and the other end of the elastic sheet 342 is connected to the end of the slide rail 13 away from the first driving member 32.

[0062] In this embodiment, the first active end 321 and the slider 3411 can be hinged to the two ends of the elastic rod 341 respectively. The elastic rod 341 includes two rods that are sleeved on each other, and there is a spring between the two rods so that the elastic rod 341 can be compressed and extended when the first active end 321 is pressed and reset.

[0063] When the first active end 321 is pressed and the elastic rod 341 is compressed, the slider 3411 can slide along the slide rail 13 in a direction away from the first driving member 32, thereby forcing the arc-shaped elastic sheet 342 to undergo compression deformation. When the first active end 321 is released from the press, the elastic deformation of the elastic sheet 342 will push the slider 3411 to reset. At the same time, the elastic reset process of the elastic sheet 342 is relatively slow, which can slow down the speed at which the device body 2 resets from the avoidance position to the display position, thus protecting the device body 2.

[0064] In one embodiment, see Figure 5The elastic reset member 34 includes a damping member 343, which is connected to both ends of the slider 3411 and abuts against the head-mounted structure 1.

[0065] In this embodiment, the damping element 343 can be a reduction wheel made of rubber or plastic. During the pressing of the first active end 321, it will squeeze the elastic rod 341, and the elastic rod 341 will squeeze the slider 3411 to slide. Since there is friction between the slider 3411 and the slide rail 13, it can achieve the effect of deceleration and damping. At the same time, there are damping elements 343 on both sides of the slider 3411. During the sliding of the slider 3411 along the slide rail 13, the damping elements 343 and the head-mounted structure 1 will generate damping through friction, which will further provide deceleration and damping effect for the pressing of the first driving element 32, preventing the device body 2 from rotating too fast when the first driving element 32 is pressed and reset, and avoiding the collision between the device body 2 and the head-mounted structure 1.

[0066] In one embodiment, see Figure 4 The drive structure 3 includes an extrusion wheel 35, and the second driven end 332 has a shaft. The extrusion wheel 35 is rotatably connected to the shaft and can drive the main body 2 of the device to switch from the display position to the avoidance position.

[0067] In this embodiment, the extrusion wheel 35 can be a soft extrusion wheel made of rubber or plastic. During the process of the second driven end 332 pushing the device body 2 from the display position to the avoidance position, the extrusion wheel 35 contacts the device body 2 and rotates relative to the shaft. The rotation of the extrusion wheel 35 can reduce the friction between it and the device body 2, making the flipping of the device body 2 more flexible and efficient.

[0068] In one embodiment, see Figure 2 and Figure 3 The head-mounted structure 1 includes temples 11 and connecting unit 12. The connecting unit 12 is provided with a first rotating shaft 121 and a second rotating shaft 122. The first rotating shaft 121 extends along a first direction, and the second rotating shaft 122 extends along a second direction.

[0069] The temple 11 is rotatably connected to the first rotating shaft 121, and the main body 2 of the device is rotatably connected to the second rotating shaft 122.

[0070] In this embodiment, the temple 11 is rotatably connected to the first rotating shaft 121 and has frictional damping to ensure the stability of the temple 11 when unfolded relative to the storage box of the connecting unit 12; the device body 2 has a sleeve fitted onto the second rotating shaft 122 to allow the device body 2 to rotate relative to the second rotating shaft 122.

[0071] When the second driving member 33 moves toward the device body 2 in the second direction, thereby pushing the device body 2 to flip from the display position to the avoidance position, the device body 2 can rotate along the second rotating shaft 122 to avoid the device body 2 from shifting during the flipping process and ensure the positional stability of the device body 2 during the flipping process.

[0072] In one embodiment, see Figure 1 and Figure 2 Both sides of the main body 2 are equipped with mirror temples 11 via connecting units 12. Each connecting unit 12 is equipped with a drive structure 3. The two drive structures 3 push the two ends of the main body 2 to achieve the flipping of the main body 2, thereby improving the stability and efficiency of the flipping of the main body 2.

[0073] In one embodiment, the drive structure 3 includes an elastic reset member 34, and the connecting unit 12 is provided with a slide rail 13.

[0074] One end of the elastic reset member 34 is connected to the first drive member 32, and the other end of the elastic reset member 34 is slidably engaged with the slide rail 13.

[0075] In this embodiment, the elastic reset member 34 can be an integral spring or an elastic plate. When the first driving member 32 is in the pressed state, the distance between the first driving member 32 and the slide rail 13 decreases, causing the elastic reset member 34 to slide along the slide rail 13 while compressing and deforming. When the first driving member 32 releases the press, the elastic deformation of the elastic reset member 34 can drive the first driving member 32 to reset. At the same time, the elastic reset process of the elastic reset member 34 is relatively slow, which can buffer the device body 2 from the avoidance position back to the display position and avoid hard collision between the device body 2 and the head-mounted structure 1.

[0076] In one embodiment, see Figure 2 and Figure 3 The second rotating shaft 122 is located on the top of the connecting unit 12, near the device body 2.

[0077] In this embodiment, the second rotating shaft 122 serves as the flipping shaft for the device body 2 to flip between the display position and the avoidance position. Positioning the second rotating shaft 122 at the top of the connecting unit 12 facilitates the upward flipping of the device body 2 when switching from the display position to the avoidance position. Furthermore, the proximity of the second rotating shaft 122 to the device body 2 facilitates the rotational connection between the device body 2 and the second rotating shaft 122, thereby improving the efficiency of the device body 2's flipping.
