The conducting members 30 are disposed in the hole wall of the accommodating hole 12 and electrically connected to the plurality of light sources 20, respectively. The light guide member 40 is disposed in the light through hole, the light guide member 40 includes a plurality of reflection portions 42 corresponding to the light sources 20 one by one, each reflection portion 42 includes an object side surface 422, an image side surface 424 opposite to the object side surface 422, and an outer side surface 426 formed between the object side surface 422 and the image side surface 424, the outer side surface 426 is disposed opposite to the light sources 20, and the reflection portions 42 are used for reflecting light rays incident from the outer side surface 426 from the light sources 20 and emitting the light rays from the image side surface 424.

The spectacle frame 10 comprises a spectacle frame 14 and a spectacle belt 16, wherein two accommodating holes 12 are formed in the spectacle frame 14 at intervals; the two ends of the strap 16 are connected to the two sides of the frame 14, respectively, for wearing on the head of a user.

The shape of the receiving hole 12 corresponds to the shape of the light guide 40. Referring to fig. 3, the wall of the accommodating hole 12 is provided with an accommodating groove 122 around the axis thereof, that is, the accommodating groove 122 is an annular structure, and the light guide member 40 is accommodated in the accommodating groove 122. Thus, light guide member 40 is not easily detached from storage hole 12, and the mounting stability is high. In the embodiment, after the light guide 40 is fixed in the receiving groove 122, the light guide 40 and the bottom of the receiving groove 122 can be bonded together by glue.

It is understood that in other embodiments, the receiving groove 122 may be omitted, and in this case, the light guide member 40 may be directly glued or welded on the hole wall of the receiving hole 12 to achieve a stable connection between the light guide member 40 and the frame 10.

grooves

122 and 124. In the present embodiment, the conducting member 30 is a ring-shaped metal sheet, and the metal sheet is disposed closely to the bottom of the accommodating groove and the bottom of the accommodating groove 124 and electrically connected to the plurality of light sources 20, respectively. Thus, the space occupied by the conducting piece 30 is small, the overall structure layout is compact, miniaturization is facilitated, and the appearance effect of the AR glasses 100 is good.

It is understood that, in other embodiments, the conducting element 30 may be a metal wire, which is disposed closely to the bottom of the accommodating groove 122 and the bottom of the accommodating groove 124 and electrically connected to the plurality of light sources 20, respectively; or grooves for accommodating the metal wires are formed in the bottom of the accommodating groove 122 and the bottom of the accommodating groove 124, and the metal wires are accommodated in the grooves.

The plurality of reflection portions 42 are of an integrated structure, specifically, the light guide member 40 is of a plate-shaped structure, and the plurality of reflection portions 42 jointly form the light guide member 40, so that the plurality of reflection portions 42 form an integrated structure, and the reflection portions 42 of the integrated structure are convenient to disassemble and assemble.

Referring to fig. 4 and 5, each of the reflective portions 42 includes a plurality of concave structures 428 formed by the object side surface 422 being concave toward the image side surface 424, and each of the concave structures 428 is disposed at regular intervals along the incident direction of the corresponding light beam and extends along the vertical direction of the incident direction of the corresponding light beam. The concave structures 428 arranged in this way can reflect the light incident from the outer side 426 and uniformly emit the light from the image side 424, so that the visual effect is better.

The cross-section of the recessed structure 428 perpendicular to the incident direction of the light guide 40 and the corresponding parallel light rays is angular (as shown in fig. 4), semicircular (as shown in fig. 5), or trapezoidal. In this way, the recessed structure 428 with corresponding cross-sectional shape can be selected to meet different scene requirements and achieve better visual effect.

The light guide member 40 further includes a light-transmitting substrate 50, and the light-transmitting substrate 50 is fixed to the object-side surface 422 of the light guide member 40 by a fixing connection manner such as gluing or welding, and is accommodated in the accommodating groove 122 together with the light guide member 40, so that the light-transmitting substrate 50 can support and protect the emission portion 42 of the light guide member 40.

In the AR glasses 100, the light source 20 and the conduction member 30 are disposed in the frame 10, so that the appearance effect is good, the light source 20 is stably mounted, and the light source is not easily detached. Since the outer side 426 of the light guide member 40 is disposed opposite to the light source 20, the light emitted from the light source 20 to the outer side 426 can be reflected by the reflection portion 42 and emitted from the image side 424 to the eyes uniformly, so that the visual effect is better. In addition, the present embodiment can further save materials and reduce the production cost, and when one of the reflection portions 42 is damaged, only the damaged reflection portion 42 needs to be replaced, so that the maintenance cost is low.

Referring to fig. 7, a third embodiment of the present application proposes AR glasses 100, where the AR glasses 100 in the third embodiment are substantially the same as the AR glasses 100 in the first embodiment, except that:

In the AR glasses 100, the light source 20 and the conduction member 30 are disposed in the frame 10, so that the appearance effect is good, the light source 20 is stably mounted, and the light source is not easily detached. Since the outer side 426 of the light guide member 40 is disposed opposite to the light source 20, the light emitted from the light source 20 to the outer side 426 can be reflected by the reflection portion 42 and emitted from the image side 424 to the eyes uniformly, so that the visual effect is better. In addition, the light guide plate has good light transmission effect and high light transmittance, and can ensure that a good visual effect is achieved.
