Description

Technical Field

[0001] This invention belongs to the field of wearable technology, and particularly relates to a head-mounted device. Background Technology

[0002] With the diversification of head-mounted devices, more and more of them are gradually integrating into people's daily lives, and an increasing number of people are using them for work. In existing head-mounted devices, the display module is fixedly connected to the shell. Once worn and the straps are tightened, the position of the display module relative to the user's eyes remains fixed. To see the real environment, the straps must be loosened and the head-mounted device removed. Therefore, some VR users need to frequently switch between putting on and taking off head-mounted devices when working. This is not only cumbersome and time-consuming, but also requires time to re-enter the interrupted program when putting it on again, seriously affecting the user experience. Summary of the Invention

[0003] In order to overcome at least one of the shortcomings of the prior art, the present invention provides a head-mounted device that allows users to see the real environment without removing it after wearing it, and has a simple structure and flexible and convenient operation, which greatly improves the user experience.

[0004] To address the problems existing in the prior art, this invention provides a head-mounted device, including a housing and a display body mounted on the front end of the housing; a flip frame is provided on the inner wall of the top of the display body, and the housing is provided with a driving mechanism for driving the flip frame to translate a set distance away from the display body and then flip it upward by a set angle;

[0005] The drive mechanism includes a motion guide structure disposed on the inner side wall of the housing, an operating component rotatably mounted on the housing, and a linkage mechanism disposed inside the housing and linked with the operating component; the flipping frame is provided with a sliding column for slidingly engaging with the motion guide structure;

[0006] By operating the operating component, in cooperation with the motion guide structure and the sliding column, the linkage mechanism drives the tilting frame to translate or tilt.

[0007] Furthermore, the motion guiding structure includes a guide rail plate and a guide groove formed on the guide rail plate; the guide groove includes a horizontally extending waist-shaped groove segment and an arc-shaped groove segment that intersects and communicates with the waist-shaped groove segment; the center of the arc-shaped groove segment coincides with the center of the front arc-shaped end of the waist-shaped groove segment;

[0008] The sliding columns are spaced two apart in the horizontal direction, and the center distance between the two sliding columns is equal to half the width of the arc-shaped groove plus the inner diameter of the arc-shaped groove.

[0009] Furthermore, the arc-shaped groove section has multiple elastic limiting protrusions spaced apart on its groove wall.

[0010] Furthermore, the central angle of the arc-shaped groove segment is 90 degrees; the display body after being flipped 90 degrees is located above the housing, and the housing is provided with a flip frame clearance opening.

[0011] Furthermore, two drive mechanisms are symmetrically arranged on the housing along the left-right direction.

[0012] Furthermore, the linkage mechanism is a double-bar linkage mechanism; one end of the double-bar linkage mechanism is fixedly connected to the end of the operating member that extends into the housing, and the other end of the double-bar linkage mechanism is hinged to the tilting frame.

[0013] Furthermore, the flipping frame includes a first connecting plate and a second connecting plate that are vertically connected;

[0014] The first connecting plate is fixed to the inner wall of the top of the display body. The second connecting plate includes a first connecting part, a bent part and a second connecting part that are perpendicularly connected to the first connecting plate. The first connecting part and the second connecting part are parallel, and the distance from the second connecting part to the inner wall of the side of the display body is less than the distance from the first connecting part to the inner wall of the side of the display body. The sliding column is disposed on the second connecting part.

[0015] Furthermore, both the double-link mechanism and the second connecting plate are located inside the guide rail plate; the double-link mechanism includes a first link and a second link that are hinged to each other at both ends;

[0016] The connecting end of the operating component passes through the guide rail plate and is fixedly connected to one end of the first connecting rod, and one end of the second connecting rod is hinged to the second connecting part; the second connecting rod is located inside the second connecting part and the first connecting rod.

[0017] Furthermore, the hinge center of the second connecting rod and the second connecting part coincides with the center of the sliding column on the rear side.

[0018] Furthermore, the display body includes a front shell and a display module disposed within the front shell; the flip frame is disposed on the inner wall of the top of the front shell.

[0019] The beneficial effects achieved by adopting the above technical solution are as follows:

[0020] The head-mounted device of the present invention includes a housing and a display body installed at the front end of the housing; a flip frame is provided on the inner wall of the top of the display body, and the housing is provided with a driving mechanism for driving the flip frame to translate a set distance away from the display body and then flip upward by a set angle; the driving mechanism includes a motion guide structure provided on the inner wall of the side of the housing, an operating component rotatably installed on the housing, and a linkage mechanism provided inside the housing and linked with the operating component; the flip frame is provided with a sliding column for slidingly engaging with the motion guide structure; by operating the operating component, the linkage mechanism drives the flip frame to translate or flip under the cooperation of the motion guide structure and the sliding column.

[0021] When the user needs to view the real environment, there's no need to remove the display. Simply rotate the control unit. Under the constraint of the motion guide structure, the linkage mechanism drives the flip frame to move horizontally away from the housing by a set distance, and then flips upward at a set angle, so that the display body is no longer directly in front of the user's eyes, allowing the user to see the real environment. When the user needs to view the virtual environment, reverse the operation of the control unit. Under the constraint of the motion guide structure, the linkage mechanism drives the flip frame to flip downward back to its original position, and then moves horizontally back towards the housing, so that the display body is once again directly in front of the user's eyes. At this time, the user can only see the virtual environment.

[0022] In summary, this invention allows users to see the real-world environment without removing the device after wearing it, and it features a simple structure and flexible, convenient operation, greatly improving the user experience. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] It should be noted that the directional indicators involved in this invention, such as front and back, up and down, left and right, refer to the relative positional relationship between the various components in a normal wearing posture. If the posture changes, the directional indicators will also change accordingly.

[0038] Depend on Figures 1 to 3As shown in the figure, the basic embodiment of the present invention, which demonstrates the main concept, discloses a head-mounted device, including a housing 1 (open at both the front and rear ends) and a display body 2 installed at the front end of the housing 1; a flip frame 3 is provided on the inner wall of the top of the display body 2, and the housing 1 is provided with a drive mechanism 4 for driving the flip frame 3 to translate a set distance away from the display body 2 and then flip it upward by a set angle (also used to reset the display body 2, see [link]). Figure 6 and Figure 9 The drive mechanism 4 includes a motion guide structure 41 disposed on the inner side wall of the housing 1, an operating component 43 rotatably mounted on the housing 1, and a linkage mechanism disposed inside the housing 1 and linked with the operating component 43; the flipping frame 3 is provided with a sliding column 31 for sliding cooperation with the motion guide structure 41; by operating the operating component 43, the linkage mechanism drives the flipping frame 3 to translate or flip under the cooperation of the motion guide structure 41 and the sliding column 31.

[0039] During operation, simply rotating the operating component 43 is sufficient to achieve the translation and flipping of the display subject 2, thereby completing the transition between viewing the virtual environment and viewing the real environment, and the program will not be interrupted; the structure is simple and the operation is flexible and convenient.

[0040] In one specific embodiment, the linkage mechanism is a double-bar linkage 42; one end of the double-bar linkage 42 is fixedly connected to one end of the operating member 43 that extends into the housing 1, and the other end of the double-bar linkage 42 is hinged to the tilting frame 3. The linkage mechanism can also be a multi-bar linkage mechanism, as long as it can drive the tilting frame 3 to translate or tilt, and is not limited here.

[0041] The display body 2 includes a front shell 21 and a display module 22 disposed in the front shell 21. The housing 1 is equivalent to the rear shell. In the initial state, the rear end of the front shell 21 extends into the housing 1. When worn normally, the display module 22 is aligned with the human eye.

[0042] The operating component 43 includes an operating knob 431 and a rotating shaft 432 fixedly connected to the operating knob 431. The rotating shaft 432 is rotatably engaged with the housing 1 and extends into the housing 1 to be fixedly connected to one end of the double linkage mechanism 42.

[0043] Figure 4 In one specific embodiment shown, the motion guide structure 41 includes a guide rail plate 411 fixed to the inner wall of the housing 1 and a guide groove 412 formed on the guide rail plate 411; the guide groove 412 includes a waist-shaped groove segment 4121 extending horizontally front and rear and an arc-shaped groove segment 4122 intersecting and communicating with the waist-shaped groove segment 4121; the center of the arc-shaped groove segment 4122 coincides with the center of the front arc-shaped end of the waist-shaped groove segment 4121 (sharing a common center); two sliding posts 31 are spaced apart in the front and rear horizontal direction, and the center distance between the two sliding posts 31 is equal to 1 / 2 times the inner diameter of the arc-shaped groove segment 4122 plus the inner diameter of the arc-shaped groove segment 4122, that is... Figure 4 The radius R of the central arc (dotted line) of the arc-shaped groove segment 4122 shown is such that when the front sliding post 31 slides horizontally to the front arc end of the waist-shaped groove segment 4121, the rear sliding post 31 is located at the open end of the arc-shaped groove segment 4122 (see 7 and ). Figure 8 This facilitates the sliding of the rear sliding column 31 around the center of the front sliding column 31 within the arc-shaped groove 4122, enabling the display body 2 to be flipped at a set angle (see...). Figure 10 and Figure 11 ).

[0044] In some embodiments, the guide plate 411 and the housing 1 are an integral structure; that is, the motion guiding structure 41 includes a guide groove 412 formed on the housing 1.

[0045] In one specific embodiment, by Figure 4 As shown, the central angle of the arc-shaped groove segment 4122 is 90 degrees; the display body 2, after being rotated 90 degrees, is located above the housing 1 (see...). Figure 9 The housing 1 is provided with a flip frame clearance opening 11, which utilizes the relative positional relationship between the housing 1 and the display body 2 to ensure the stability of the display body 2 after it is flipped 90 degrees.

[0046] In another specific embodiment, by Figure 5 As shown, multiple elastic limiting protrusions 413 are spaced apart on the groove wall of the arc-shaped groove segment 4122; this setting can realize the adjustment of multiple flip angles of the display body 2 and the stability after adjustment, that is, multi-level adjustment can be realized; in addition, the central angle of the arc-shaped groove segment 4122 can also be set to any angle other than 90 degrees shown in the figure.

[0047] In another specific embodiment, the flip frame 3 includes a first connecting plate 32 and a second connecting plate 33 connected vertically. The first connecting plate 32 is fixed to the inner top wall of the front shell 21 in the display body 2. The second connecting plate 33 includes a first connecting part 331, a bent part 332, and a second connecting part 333 that are perpendicularly connected to the first connecting plate 32. The first connecting part 331 is parallel to the second connecting part 333 (preferably parallel to the left and right sides of the front shell 21), and the distance from the second connecting part 333 to the inner side wall of the front shell 21 in the display body 2 is less than the distance from the first connecting part 331 to the inner side wall of the same front shell 21. The sliding column 31 is disposed on the second connecting part 333. This arrangement avoids interference between the flip frame 3 and the shell 1 and the display body 2 after installation, ensuring the reliability of the flip frame 3's translation and flipping.

[0048] In another specific embodiment, both the double-link mechanism 42 and the second connecting plate 33 are located inside the guide rail plate 411. The double-link mechanism 42 includes a first link 421 and a second link 422 hinged at both ends. The connecting end of the operating member 43 passes through the clearance hole 414 on the guide rail plate 411 and is fixedly connected to one end of the first link 421. One end of the second link 422 is hinged to the second connecting part 333. The second link 422 is located inside the second connecting part 333 and the first link 421. Preferably, the thickness of the second connecting part 333 is equal to the thickness of the first link 421, which can prevent the double-link mechanism 42 from moving left and right during the driving process and further improve reliability. The hinge center of the second link 422 and the second connecting part 333 coincides with the center of the sliding column 31 on the rear side. This arrangement can further ensure that the double-link mechanism 42 effectively drives the tilting frame 3 under the constraint of the guide groove 412.

[0049] In some embodiments, two drive mechanisms 4 are symmetrically arranged on the inner wall of the housing 1 in the left-right direction; the structure of the flipping frame 3 can be adaptively adjusted as needed. Optionally, the flipping frame 3 can be adjusted to include a first connecting plate 32 and two opposing second connecting plates 33. This arrangement can further improve the stability and reliability of the flipping frame 3 during translation and flipping.

[0050] The working principle is briefly explained below based on the above structure:

[0051] When the user needs to view the real-world environment, there is no need to remove the head-mounted device. Simply rotate the operating knob 431 of the operating component 43 in the forward direction. Under the constraint of the waist-shaped groove 4121 in the guide groove 412, the double-link mechanism 42 drives the flip frame 3 and the display body 2 to move forward and away from the housing 1 by a set distance (see...). Figure 2 and Figure 7 (Rotate 46.7 degrees, translate 13mm), at this time the front sliding column 31 slides horizontally to the front arc end of the waist-shaped groove section 4121, and the rear sliding column 31 is exactly located at the opening end of the arc-shaped groove section 4122 (see Figure 8 The initial state has been completed. Figure 1 From the intermediate state ( Figure 6 The operation knob 431 of the operating component 43 continues to rotate forward. Under the constraint of the arc-shaped groove 4122, the double linkage mechanism 42 drives the flip frame 3 and the display body 2 to flip at the set angle. Figure 10 As shown, rotate 31.9 degrees and flip 90 degrees, that is, the rear sliding column 31 slides around the center of the front sliding column 31 in the arc-shaped groove 4122 to the end; during the flipping process, the flipping frame clearance opening 11 on the housing 1 avoids the first connecting part 331 in the second connecting plate 33 of the flipping frame 3, ensuring that after flipping 90 degrees, the display body 2 is located above the housing 1, completing the transition from the intermediate state to the flipped state. Figure 10 The transformation of the display subject 2 allows the human eye to see the real environment without being directly in front of it.

[0052] Conversely, when the user needs to view the virtual environment, they only need to rotate the operation knob 431 of the operation component 43 in the opposite direction to complete a reset from the flip state to the intermediate state and then to the initial state, so that the display body 2 is once again blocking the viewer's eyes. At this time, the viewer's eyes can only see the virtual environment. The specific working process is described above and will not be elaborated here.

[0053] The various embodiments in this specification are described in a progressive or parallel manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.

[0054] In summary, this invention allows users to see the real-world environment without removing the device after wearing it, and it features a simple structure and flexible, convenient operation, greatly improving the user experience.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
