Referring to fig. 1 to fig. 3, a schematic structural diagram of a light guide device 100 according to an embodiment of the present invention is shown, in which the light guide device 100 is applied to a magnifier module, the magnifier module includes a lens assembly, and the lens assembly has an image side end and an object side end. The light guide device 100 includes a light inlet portion 10, a mounting hole 11, a light splitting structure 12 and a reflection structure, wherein the light inlet portion 10 is configured to receive incident light, the mounting hole 11 includes a first opening 11a and a second opening 11b, the mounting hole 11 is configured to mount a lens assembly, an image side end faces the first opening 11a, an object side end faces the second opening 11b, an outer periphery of the second opening 11b is provided with a light outlet portion 14 configured to transmit light out of the mounting hole 11, a position of the light inlet portion 10 is offset from a position of the light outlet portion 14 in a plane perpendicular to an axis a of the mounting hole 11, the light splitting structure 12 is disposed corresponding to the light inlet portion 10, the light splitting structure 12 is configured to split the incident light received by the light inlet portion 10 into at least two sub-light, and the reflection structure is configured to transmit each sub-light to a different light outlet position of the light outlet portion 14.

The light emitting portion 14 may be an annular light emitting surface disposed around the second opening 11 b. In fig. 1, the axis a of the mounting hole is indicated by a dotted line a, and a dotted line plane xy indicates a plane perpendicular to the axis a of the mounting hole 11. When the lens assembly is mounted in the mounting hole 11, the optical axis of the lens assembly coincides with the axis a of the mounting hole 11.

On one hand, in the present embodiment, the lens module is installed through the installation hole 11, and the image side end and the object side end of the lens module face the first opening 11a and the second opening 11b, the light emitting portion 14 for transmitting light out of the installation hole 11 is disposed at the periphery of the second opening 11b, and an external light source is used to provide incident light to the light inlet portion 10 and transmit the incident light to the light emitting portion 14 under the light guiding effect of the light guiding device 100, so that when the object side end of the lens module is observed near the object to be observed, the light transmitted by the light emitting portion 14 can illuminate the object to be observed, and the observation clarity is improved. The light guide device 100 itself cannot emit light, and the external light source is a light source independent from the light guide device 100, for example, the external light source may be a flash lamp of an intelligent terminal or a light source of a magnifying glass module, a flashlight, and the like, which is not limited in this embodiment.

It can be understood that, in practical applications of the light guide device 100, the light inlet portion 10 needs to be close to an external light source, the object side end of the lens assembly needs to be close to an object to be observed, and the image side end needs to be close to the eyes of a user for the user to directly observe the object to be observed or close to a camera of the intelligent terminal for the camera to shoot. That is, in practical applications, the light guide device 100 needs to consider the arrangement of each participating object (such as an object to be observed, an external light source, a user, a camera, etc.) to avoid interference when the participating objects are arranged, so that the light inlet portion 10 cannot be overlapped with the light outlet portion 14. Therefore, the present embodiment prevents the light guide device 100 from interfering with each other in practical use by deviating the position of the light inlet portion 10 from the position of the light outlet portion 14 in a plane perpendicular to the axis a of the mounting hole 11, thereby ensuring that the light guide device 100 can be used normally. Specifically, the light guide device 100 includes a first surface 100a and a second surface 100b that are disposed opposite to each other, the first surface 100a has the light entrance portion 10, the mounting hole 11 penetrates through the first surface 100a and the second surface 100b, the first opening 11a is located on the first surface 100a, and the second opening 11b is located on the second surface 100 b. It is understood that, in practical applications of the light guide device 100, the first surface 100a of the light guide device 100 may face a user, a camera, an external light source, and the second surface 100b may face an object to be observed.

Further, it is considered that the light guide device 100 cannot simply directly transmit the incident light received by the light entering portion 10 to the light exiting portion 14, for example, in a straight line, due to the positional relationship between the light entering portion 10 and the light exiting portion 14. Therefore, the light path of the light guide device 100 is designed in the present embodiment, and the light splitting structure 12 and the reflection structure are used to conduct the incident light entering the light inlet portion 10 substantially along the vertical direction to the light outlet portion 14 substantially in the transverse direction, and then conduct the incident light to the light outlet portion 14 substantially in the vertical direction, wherein the substantially transverse conduction is mainly performed to compensate the deviation position of the light inlet portion 10 and the light outlet portion 14, so that the incident light can smoothly reach the light outlet portion 14 and pass through the mounting hole 11.

Moreover, when the light splitting structure 12 and the reflection structure transmit incident light, the light splitting structure 12 can split the incident light into at least two paths of sub-light, and transmit each path of sub-light to different light emitting positions of the light emitting part 14 through the reflection structure, so that the light transmitting uniformity of the light emitting part 14 is improved, and when the transmitted light irradiates to an object to be observed, the brightness of the object to be optically wiped is uniform, so that the observation definition is further improved.

On the other hand, the lens assembly is installed through the installation hole 11 of the optical device in the embodiment, so that the overall structure of the magnifier module can be more compact, and the overall size of the magnifier module can be reduced.

In some embodiments, the light splitting structure 12 includes a first light splitting surface 12a and a second light splitting surface 12b, the first light splitting surface 12a and the second light splitting surface 12b are obliquely oriented toward the light entering portion 10, the first light splitting surface 12a and the second light splitting surface 12b can reflect the incident light toward different directions and form a first sub light and a second sub light, the reflection structure includes a first reflection surface set 131 and a second reflection surface set 132, the first reflection surface set 131 is used for guiding the first sub light to a first position of the light exiting portion 14, the second reflection surface set 132 is used for guiding the second sub light to a second position of the light exiting portion 14, and the second position and the first position are different light exiting positions of the light exiting portion 14. It can be understood that, through the light splitting effect of first plain noodles 12a and second plain noodles 12b, form first sub light and second sub light, and utilize first plane of reflection group 131 and second plane of reflection group 132 to conduct first sub light and second sub light to primary importance and second place respectively, thereby make light-emitting portion 14 pass through to the mounting hole 11 outside at two light-emitting position, light-emitting portion 14 printing opacity is comparatively even, avoid light to concentrate on a certain position of light-emitting portion 14 to pass through, lead to waiting to observe the object part region darker, the part region is lighter, the condition of the definition of influence observation takes place.

Alternatively, the first position and the second position are symmetrically disposed about the center plane yz of the mounting hole 11.
