[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0043] Regarding the problem that the existing hinge structure relies on the pre-tightening force of the hinge structure for limit, and the hinge structure is prone to looseness after long-term use, resulting in poor stability. In the flattened state or the folded state, the elastic member presses the first abutting portion and the second abutting portion in the embodiments of the present utility model, achieving a limiting effect and significantly improving the structural stability.
[0044] The following combines Figures 1 to 4 , and describes the embodiments of the present utility model.
[0045] According to the embodiments of the present utility model, on the one hand, as Figure 1 shown, an AR glasses hinge structure is provided, mainly including: a central shaft 1, a first connecting portion 2, a second connecting portion 3, a sliding member 4, and an elastic member 5. The first connecting portion 2 is sleeved on the opposite ends of the central shaft 1. The second connecting portion 3 is sleeved on the opposite ends of the central shaft 1 and is located inside the first connecting portion 2. One of the first connecting portion 2 and the second connecting portion 3 is adapted to be connected to the glasses body of the AR glasses, and the other is adapted to be connected to the temple of the AR glasses. The sliding member 4 is sleeved on the central shaft 1, and one side surface abuts against the inner surface of one side of the second connecting portion 3. A first abutting portion 401 is provided on the surface of the sliding member 4 that abuts against the second connecting portion 3, and a second abutting portion 301 is correspondingly provided on the surface of the second connecting portion 3 that abuts against the sliding member 4. The elastic member 5 is sleeved on the central shaft 1 and abuts against the opposite side surface of the sliding member 4 and the inner surface of the opposite side of the second connecting portion 3. The AR glasses hinge structure has a flattened state and a folded state. In the flattened state or the folded state, the first abutting portion 401 and the second abutting portion 301 are pressed against each other by the elastic member 5.
[0046] The AR glasses hinge structure provided by the embodiments of the present utility model is convenient for users to wear the AR glasses in the flattened state and convenient for storing the AR glasses in the folded state. During the process of switching between the flattened state and the folded state, the second abutting portion 301 of the second connecting portion 3 presses the first abutting portion 401 of the sliding member 4, causing the sliding member 4 to move axially along the central shaft 1 and compress the elastic member 5. The elastic member 5 is compressed. When approaching the flattened state or the folded state, the elastic member 5 rebounds, releases the elastic force, and presses the first abutting portion 401 and the second abutting portion 301, achieving a limiting effect, not easily affected by the outside, significantly improving the structural stability, and being convenient for use.
[0047] Specifically, the first connecting portion 2 and the second connecting portion 3 rotate relative to each other around the central axis 1, so that the spectacle body rotates relative to the temple. The first connecting portion 2 is provided with a pair of first lugs 201, and is movably sleeved on the central axis 1 through the pair of first lugs 201. A connecting plate 202 is further provided between the pair of first lugs 201. Similarly, the second connecting portion 3 is provided with a pair of second lugs 302, and is movably sleeved on the central axis 1 through the pair of second lugs 302. The second connecting portion 3 is nested inside the first connecting portion 2. The elastic member 5 is movably sleeved on the central axis 1. The sliding member 4 and the elastic member 5 are nested inside the second connecting portion 3.
[0048] In one embodiment, as Figure 1 and Figure 2 shown, a first guiding surface is provided on the surface of the sliding member 4 that abuts against the second connecting portion 3. The first guiding surface serves as the first abutting portion 401. A second guiding surface is provided on the surface of the second connecting portion 3 that abuts against the sliding member 4. The second guiding surface serves as the second abutting portion 301. In the flattened state or the folded state, the first guiding surface fits with the second guiding surface.
[0049] In the embodiment of the present utility model, by using the first guiding surface as the first abutting portion 401 and the second guiding surface as the second abutting portion 301, the contact area between the sliding member 4 and the second connecting portion 3 in the flattened state or the folded state can be increased, and the structural stability can be further improved.
[0050] Further, in one embodiment, the first guiding surface is a first inclined surface, and the second guiding surface is a second inclined surface. In the flattened state or the folded state, the first inclined surface fits with the second inclined surface. When approaching the flattened state or the folded state, the elastic member 5 can push the sliding member 4 to slide quickly along the first inclined surface and the second inclined surface and be clamped, which is beneficial to realizing quick automatic limiting and convenient for use.
[0051] In some other embodiments, the first guiding surface and the second guiding surface can also be arc surfaces, so that the sliding member 4 can slide relative to the second connecting portion 3.
[0052] Furthermore, in one embodiment, the first inclined surface and the second inclined surface are inclined at 45° relative to the axial direction of the central axis 1. As Figure 2 shown, in the flattened state, the first connecting portion 2 and the second connecting portion 3 are parallel, so that the spectacle body and the temple are kept parallel, which is convenient for wearing the AR glasses. As Figure 3 and Figure 4 shown, in the folded state, the first connecting portion 2 and the second connecting portion 3 are perpendicular to each other, so that the spectacle body and the temple are perpendicular to each other in the folded state, which is convenient for storing the AR glasses.
[0053] In one embodiment, a plurality of first protrusions and a plurality of first grooves are provided at intervals on the surface of the sliding member 4 that abuts against the second connecting portion 3. A plurality of second protrusions and a plurality of second grooves are provided at intervals on the surface of the second connecting portion 3 that abuts against the sliding member 4. In the flattened state or the folded state, the first protrusions slide into the second grooves, and the second protrusions slide into the first grooves. The sliding member 4 and the second connecting portion 3 are respectively provided with a plurality of protrusions and a plurality of grooves, and abut against each other in the form of protrusions and grooves, with a simple structure, which is convenient for manufacturing and use.
[0054] Specifically, the contour of the first protrusion is adapted to the contour of the second groove, and the contour of the second protrusion is adapted to the contour of the first groove. When switching from the flattened state to the folded state, or from the folded state to the flattened state, the second protrusion of the second connecting portion 3 first disengages from the first groove, the first protrusion disengages from the second groove, and the elastic member 5 is compressed. Then, after passing over the highest points of the first protrusion and the second protrusion, the elastic member 5 releases pressure and pushes the second protrusion into the next first groove, and pushes the first protrusion into the next second groove, achieving fixed limit and completing the state switch.
[0055] Exemplarily, both side surfaces of the first protrusion are inclined surfaces, and both side surfaces of the second groove are adapted to the first protrusion as inclined surfaces. Similarly, both side surfaces of the second protrusion are inclined surfaces, and both side surfaces of the first groove are adapted to the second protrusion as inclined surfaces. So that the second connecting portion 3 can slide along the inclined surface when rotating forward or backward relative to the sliding member 4.
[0056] It can be understood that the number of the first protrusions, the first grooves, the second protrusions and the second grooves can be selected and set according to actual needs. Exemplarily, three first protrusions, three first grooves, three second protrusions and three second grooves are provided.
[0057] In one embodiment, the elastic member 5 is a rectangular spring. It can improve the resilience and is convenient for pressing the sliding member 4 and the second connecting portion 3.
[0058] In one embodiment, as Figure 1 shown, the AR glasses hinge structure further includes a pair of snap rings 6. Card slots 101 are respectively formed at opposite ends of the central shaft 1. The pair of snap rings 6 are respectively arranged on the card slots 101 and are located outside the first connecting portion 2 to clamp the first connecting portion 2. Since the pair of snap rings 6 are respectively arranged on the card slots 101 and are located outside the first connecting portion 2, it is possible to prevent the first connecting portion 2 and the second connecting portion 3 from falling off the central shaft 1.
[0059] In one embodiment, in the flattened state or the folded state, the first connecting portion 2 abuts against the second connecting portion 3. As Figure 2 shown, in the flattened state, the main body portions of the first connecting portion 2 and the second connecting portion 3 abut against each other. As Figure 3 and Figure 4As shown, in the folded state, one side surface of a pair of second lugs 302 of the second connecting portion 3 abuts against the main body portion of the first connecting portion 2. In the embodiment of the present utility model, the first connecting portion 2 and the second connecting portion 3 can be made to switch between the flattened state and the folded state only within a limited angle by means of their own structures, which plays a role of further limiting, thereby further improving the structural stability.
[0060] In one embodiment, as Figure 1 shown, a baffle 402 is provided on the outer side of the sliding member 4. The baffle 402 abuts against the first connecting portion 2 and there is a gap between the baffle 402 and the second connecting portion 3. The sliding member 4 is connected to the second connecting portion 3 through the baffle 402 and there is a gap between the sliding member 4 and the second connecting portion 3. When the sliding member 4 switches between the flattened state and the folded state, the rotation of the sliding member 4 is restricted by the connecting plate 202 of the first connecting portion 2, and the sliding member 4 can only move axially along the central axis 1 and cannot rotate, preventing the first abutting portion 401 from being misaligned with the second abutting portion 301.
[0061] According to an embodiment of the present utility model, on the other hand, an AR glasses is further provided, which mainly includes: a glasses main body, temple arms, and an AR glasses hinge structure. One of the first connecting portion 2 and the second connecting portion 3 is connected to the glasses main body, and the other is connected to the temple arms.
[0062] Because the AR glasses includes an AR glasses hinge structure and has the same effect as the AR glasses hinge structure, that is, during the process of switching between the flattened state and the folded state, the second abutting portion 301 of the second connecting portion 3 presses the first abutting portion 401 of the sliding member 4, so that the sliding member 4 moves axially along the central axis 1 and presses the elastic member 5. The elastic member 5 is compressed. When approaching the flattened state or the folded state, the elastic member 5 rebounds, releases the elastic force and presses the first abutting portion 401 and the second abutting portion 301 tightly, which plays a limiting effect, is not easily interfered by the outside world, significantly improves the structural stability, and is convenient for use.
[0063] Specifically, since users generally rotate the temple arms to wear or store the AR glasses, the first connecting portion 2 is connected to the glasses main body, and the second connecting portion 3 is connected to the temple arms. The connection method can adopt a fastening connection, such as welding, gluing, etc., or a detachable connection, such as snap connection, plug connection, screw connection, etc. The specific setting can be selected according to actual needs. In this regard, the embodiments of the present utility model do not make excessive restrictions.
[0064] To implement the basic functions of the AR glasses, the AR glasses in this embodiment may further include other necessary modules or components, such as cameras, sensors, etc. It should be noted that for the other necessary modules or components included in the AR glasses, any suitable existing structure can be selected. To clearly and briefly illustrate the technical solutions provided in this embodiment, the above parts will not be elaborated herein, and the accompanying drawings of the specification have also been correspondingly simplified. However, it should be understood that the scope of the present utility model is not limited thereby.
[0065] Although the embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations all fall within the scope defined by the appended claims.
