Through the structure, the glasses legs are designed in a segmented mode and comprise the first glasses leg segment and the second glasses leg segment, the angle adjusting part is arranged at the joint of the first glasses leg segment and the second glasses leg segment, and the included angle between the first glasses leg segment and the second glasses leg segment can be changed through the angle adjusting part, so that the angles of the glasses legs can be adjusted to adapt to the sizes of head circumferences of different users.

In some embodiments, the range of the opening and closing included angle of the two temple segments connected to each other on the same side may be set according to actual needs, for example, may be set to 60 degrees to 200 degrees, or 70 degrees to 180 degrees, etc.

With continued reference to fig. 1, in some embodiments, first left temple segment 126 and first right temple segment 136 are connected to the left and right ends of front component 11, respectively, in a manner that may be a hinged connection so as to integrate first left temple segment 126 and first right temple segment 136, respectively, with front component 11 and capable of forming an angle that can vary from approximately 0 degrees to 90 degrees; first left temple segment 126 and first right temple segment 136 may also be fixedly attached to the left and right ends of front member 11.

The display module is used for displaying the display image to the visual field of a user in a projection or other near-eye imaging mode. The imaging part of the display module is usually fixed in the area directly in front of the user's glasses, while the control part of the display module can be arranged in the glasses frame, preferably in the front part or on the first temple segment.

In some embodiments, the display module comprises a projector, a light path, and a lens 117, the front member has substantially the same structure as the frame, and the lens can be mounted in the frame. The projector light machine is used for generating virtual image light. The optic can be a lens, a display assembly, or a combination of any one or more of the foregoing. Because the process of transmitting the virtual image light to the lens comprises at least one light path, in order to ensure that the light path is not influenced, the angle between the projection light machine and the lens is fixed. In some embodiments, the projector may be placed inside the first left temple segment 126 and/or the first right temple segment 136, and the first left temple segment 126 and/or the first right temple segment 136 may be integrated with the front piece 11, respectively, to ensure that the angle between the projector and the lens is fixed and the optical path is not affected.

In some of these embodiments, the device circuitry includes, but is not limited to, at least one of: a driving circuit, a sensor circuit, or other control circuits of the display module.

In some of these embodiments, the rear end of the second temple segment of one of the two temples is provided with a cavity. The shape and size of the cavity can be determined according to the size and height of a circuit board or a component contained in the cavity, and meanwhile the wearing experience of a user is considered. And an equipment circuit is arranged in the cavity and is electrically connected with the display module through a lead embedded in the glasses leg so as to realize the control of the display module. Since the related art device circuits are generally concentrated on the front part or the front ends of the temples, the nose bridge is subjected to a large pressure, which causes discomfort to the user during wearing for a long time. Through foretell structure, with head-mounted display device's weight decentralization, not concentrate on the mirror leg front end, and with partial weight dispersion to mirror leg rear end for weight can distribute at glasses front end and rear end more evenly, and the atress is even, wears more comfortablely, firm.

In some of these embodiments, to further even the weight distribution of the head mounted display device, the rear end of the second temple segment of both temples is opened with a cavity, respectively a first cavity 1274 and a second cavity 1374. Wherein the device circuitry is divided into two parts, one part being arranged in the first cavity and the other part being arranged in the second cavity.

The structure of the temple will be described below using the left temple as an example. With continued reference to fig. 1, left temple 12 includes front temple segment 126, middle temple segment 1271, and rear temple segment 1272; the three temple segments are connected in front-to-middle-to-rear order with the front end of front temple segment 126 connected to the left end of front piece 11. The front temple segment 126 described above corresponds to the first left temple segment 126 of the above-described embodiment; middle temple segment 1271 and rear temple segment 1272 may be one piece or may be fixedly or removably attached, with the attached temple segments corresponding to second left temple segment 127 of the above-described embodiment; where the front end of second left temple segment 127 is middle temple segment 1271 and the rear end is rear temple segment 1272.

A first cavity 1274 is formed in rear temple segment 1272 for receiving all or a portion of the device circuitry, such as projector driver circuitry, so that the weight of the head mounted display device is distributed and not concentrated on front temple segment 126 and middle temple segment 1271, thereby distributing the weight evenly and applying force evenly, and making the wearer more secure.

For comfort of wear, the width of middle temple segment 1271 is smaller than the width of front temple segment 126 and rear temple segment 1272, and rear temple segment 1272 is suitably widened such that the junction of the rear end of middle temple segment 1271 and rear temple segment 1272 forms an arc similar to the contour of the ear root, which is more comfortable for the user to wear.

The structure of the right temple arm may be substantially the same as the structure of the left temple arm, and will not be described in detail herein.

The structure of the angle adjusting section will be described below taking the angle adjusting section of the left temple as an example. Fig. 2 is a schematic structural view of an angle adjusting part according to an embodiment of the present application, and as shown in fig. 2, the first angle adjusting part 128 includes: a rotation connecting portion and an elastic portion 1281; the rotation connection part comprises a rotation shaft 1282 and two rotation arms (1283, 1284). Both ends of pivot 1282 are secured to one of front temple segment 126 or middle temple segment 1271. Two swivel arms correspondingly connect front temple segment 126 and middle temple segment 1271, respectively; two ends of the elastic part 1281 are respectively connected with the two rotating arms correspondingly. Elastic portion 1281 can provide the pretightening force that makes the contained angle that opens and shuts of front temple section 126 and middle temple section 1271 reduce, makes middle temple section 1271 and rear temple section 1272 can press from both sides tight user's head circumference, guarantees to wear firmly. Wherein, the wearing experience of user is considered to the size of pretightning force, avoids the pretightning force too big and leads to user's comfort to reduce.

With continued reference to fig. 2, in some of these embodiments, the swivel connection of the left temple arm includes two swivel arms, a first swivel arm 1283 and a second swivel arm 1284, respectively. First pivot arm 1283 includes a first pivot aperture 12831 and a first pivot rod 12832, first pivot aperture 12831 and pivot 1282 being in rotational engagement, the pivot rod of the first pivot arm being connected to front temple segment 126. The rotation rod of the first rotation arm and the front temple segment 126 may be a separate structure rigidly connected to each other, or may be an integral structure. The second rotary arm 1284 includes a second rotary shaft hole 12841 and a second rotary shaft 12842, the first rotary shaft hole 120 is engaged with the rotary shaft 1282, and the second rotary shaft 12842 of the second rotary arm is connected with the middle temple segment 1271 (or the second left temple segment 127). Likewise, the pivoting lever of the second pivoting arm and the middle leg segment 1271 may be a separate structure rigidly connected to each other or may be an integral structure.

In some embodiments, where both ends of the shaft 1282 are secured to one of the front temple segment 126 or the center temple segment 1271, the pivot arm of one of the first and second pivot arms may not be provided with a pivot hole, but rather both ends of the shaft 1282 may be secured to one of the front temple segment 126 or the center temple segment 1271 by a rigid connection.

It should be noted that the structure of the rotation connecting portion is not limited to the structure described in the above embodiment.

With continued reference to FIG. 2, in some of these embodiments, the elastic portion 1281 of the left temple comprises a torsion spring. The torsion spring of the embodiment may be a single-arm torsion spring or a double-arm torsion spring.

In some embodiments, the torsion spring of the resilient portion 1281 is a two-arm torsion spring that includes a resilient coil, a first rotational arm 12811, and a second rotational arm 12812. The first rotational arm 12811 and the second rotational arm 12812 are formed by extending the ends of the resilient coil outwardly. The elastic coil is sleeved on the rotating shaft 1282 to realize the position fixation of the torsion spring. A first rotational arm 12811 is connected to front temple segment 126 and a second rotational arm 12812 is connected to middle temple segment 1271. As the opening and closing angle of front temple segment 126 and middle temple segment 1271 increases, the torsion spring stores energy, thereby providing a pre-load for reducing the opening and closing angle of front temple segment 126 and middle temple segment 1271.

In other embodiments, the torsion spring of the resilient portion 1281 is a single-armed torsion spring that includes a resilient coil and a rotational arm. The resilient coil is rigidly connected to either the shaft 1282 or the front temple segment 126 and the rotational arm is connected to the middle temple segment 1271. As the opening and closing angle of front temple segment 126 and middle temple segment 1271 increases, the torsion spring stores energy, thereby providing a pre-load for reducing the opening and closing angle of front temple segment 126 and middle temple segment 1271.

In this embodiment, front temple segment 126 further includes a first securing structure 1261, and middle temple segment 1271 further includes a second securing structure 1273; the first and second securing structures 1261, 1273 each form an inverted hook-shaped catch. The rotating force arm of the torsion spring is pressed into the barb of the fixing structure to realize the connection of the rotating force arm and the glasses leg sections. In order to prevent the rotary force arm from falling off from the fixing structure due to the pulling force along the extension direction of the glasses legs, the tail end of the rotary force arm is L-shaped so as to hook the fixing structure to prevent the rotary force arm from generating larger displacement along the extension direction of the glasses legs. The rotational force arm may also be provided to the temple segment in other ways, for example by means of adhesive bonding or welding.

The elastic member 1281 of the above embodiment is described by taking a torsion spring as an example, but the structure of the elastic member 1281 is not limited to the torsion spring, and other structures that can perform the same function may be adopted. For example, the torsion spring may be replaced by a leaf spring, the center of which is fixed on the rotating shaft 1282, and both ends of which extend to form two rotating arms that respectively connect the two temple segments correspondingly, thereby providing a pre-load force for reducing the opening and closing angle of the front temple segment 126 and the middle temple segment 1271.

The structure of the right temple arm may be substantially the same as the structure of the left temple arm, and will not be described in detail herein.
