As shown in fig. 1 and 7, as an embodiment, a limiting member 150 is provided on an outer side surface of the optical housing 100, and the limiting member 150 is used to limit rotation of the optical housing 100. For example, when the optical engine 10 of the embodiment of the present application is applied to a scenario where the sleeve 22 is to be assembled in the optical waveguide 111, a portion of the optical engine 10 is accommodated in the sleeve 22, and the stopper 150 disposed on the outer side surface of the optical engine housing 100 is engaged with the sleeve 22 to limit the rotation of the optical engine housing 100 partially accommodated in the sleeve 22, at this time, a space for dispensing can be formed between the assembly groove 110 on the outer side wall of the optical engine housing 100 and the sleeve 22 to bond and fix the optical engine housing 100 and the sleeve 22. Like this, under the scene that needs to use ray apparatus 10 of this application embodiment collocation sleeve 22 in order to assemble on light waveguide 211, set up locating part 150 at the lateral surface of ray apparatus 10, when sleeve 22 cover is in the outside of ray apparatus casing 100, locating part 150 carries out the screens cooperation with sleeve 22 inner peripheral wall, thereby reduce the equipment clearance between sleeve 22 and ray apparatus 10, and locating part 150 restriction ray apparatus casing 100 is rotatory, can increase the rotatory degree of difficulty of ray apparatus 10 relative to sleeve 22, improve the installation stability of ray apparatus 10 equipment on the light waveguide 211 of smart glasses 20, and reduce the phenomenon probability that ray apparatus 10 that assembles on light waveguide 211 takes place to rock, simultaneously reduce the phenomenon probability that ray apparatus 10 produces the deviation in position degree for the position of light waveguide 211, and reduce the alignment degree of difficulty between ray apparatus 10 and the light waveguide 211. In addition, after the difficulty of rotating the optical machine 10 relative to the sleeve 22 is increased, the influence of the rotation of the optical machine 10 on the glue spraying in the gap between the sleeve 22 and the optical machine 10 can be reduced, so that the glue spraying difficulty is reduced, and the assembly difficulty between the optical machine 10 and the sleeve 22 is reduced. In one embodiment, the limiting members 150 are disposed on two opposite sides of the optical housing 100 along the radial direction of the lens module 300, so as to improve the effect of limiting the rotation of the optical housing 100.

As shown in fig. 1, 5 and 7, as an embodiment, the limiting member 150 is disposed adjacent to the side of the assembly groove 110 near the light source 200, it is understood that the limiting member 150 is located above the assembly groove 110 when the light engine 10 is disposed perpendicular to a horizontal plane. Thus, when the optical engine 10 according to the embodiment of the present application is applied to a scene where the sleeve 22 is to be assembled on the optical waveguide 111, the sleeve 22 can be sleeved from the bottom of the optical engine 10 to the top, and components such as the circuit board 400 and the connector 500 disposed on the optical engine housing 100 are not affected.

For example, when the optical engine 10 of the embodiment of the present application is applied to a scenario where the optical waveguide 111 is to be assembled with the sleeve 22, the limiting groove 151 is used for being clamped with the inner peripheral surface of the sleeve 22, and generally, the inner peripheral surface of the sleeve 22 may be disposed on a clamping protrusion (not labeled) that is clamped and matched with the limiting groove 151, so as to simplify the connection between the optical engine housing 100 and the sleeve 22. In one embodiment, along the axial direction of the lens module 300, the outer side wall of the optical housing 100 is cut away from the bottom of the optical housing 100 toward the direction away from the assembly groove 110, so as to form a limiting groove 151, and a projection of the limiting groove 151 in the radial direction of the lens module 300 is square. Thus, when the optical engine housing 100 is assembled into the sleeve 22 from top to bottom, the assembly groove 110 slides on the surface of the clamping protrusion from top to bottom along the length direction of the clamping protrusion, and finally the limiting groove 151 is clamped at the top of the clamping protrusion, so that the assembly mode of the optical engine 10 and the sleeve 22 is simplified.

As shown in fig. 1, 5 and 7, as an embodiment, the limiting member 150 further includes a limiting protrusion 152 protruding from a surface of the limiting groove 151 opposite to the lens module 300, where the limiting protrusion 152 is configured to cooperate with the limiting groove 151 to form a clamping position together. In this way, when the optical engine 10 of the embodiment of the present application is applied to a scenario where the optical waveguide 111 is assembled with the sleeve 22, the limiting protrusion 152 can cooperate with the limiting groove 151 to be clamped with the inner circumferential surface of the sleeve 22, so as to improve the connection stability of the optical engine 10 and the sleeve 22. In one embodiment, the limiting protrusion 152 may have elasticity, so that when the limiting groove 151 slides along the length direction of the clamping protrusion, the limiting protrusion 152 can be extruded and deformed, and when the limiting protrusion 152 moves to a position where the limiting protrusion 152 can be clamped, the limiting protrusion 152 is deformed again to restore to the original shape, which helps to reduce damage to the inner circumferential surface of the sleeve 22 when the limiting groove 151 drives the limiting protrusion 152 to move.

As shown in fig. 3 and 7, in one embodiment, the limiting groove 151 includes a first clamping surface 1511 and a second clamping surface 1512, and the first clamping surface 1511 extends along a length direction of the optical engine housing 100. The second clamping surface 1512 extends from a side of the first clamping surface 1511 away from the mounting groove 110 in a direction away from the optical engine housing 100. The first clamping surface 1511 and the second clamping surface 1512 enclose a clamping space, and an included angle formed by the first clamping surface 1511 and the second clamping surface 1512 is smaller than or equal to 90 degrees. Such arrangement of the limiting groove 151 helps to improve the connection stability of the optical engine housing 100 and the sleeve 22.

In this way, the optical machine 10 is directly fixed on the optical waveguide 211 of the smart glasses 20, so that the difficulty of rotation of the optical machine 10 is increased, the installation stability of the optical machine 10 assembled on the optical waveguide 211 of the smart glasses 20 is improved, and the probability of shaking of the optical machine 10 assembled on the optical waveguide 211 is reduced. Meanwhile, the optical machine 10 can be used as an optical machine 10 module, so that the volume of the optical machine 10 module is reduced, the space of the optical machine 10 module occupying the intelligent glasses 20 on the whole is reduced, the volume of the intelligent glasses 20 on the whole is further reduced, and the miniaturized design of the intelligent glasses 20 is facilitated.
