[0032] As shown in Figure 1 and Figure 2 The optical machine assembly structure provided by the embodiment of the present application is applied to smart glasses, which comprises a sleeve 20, an optical machine 30 and a frame body 40.
[0033] The sleeve 20 is provided with a mounting hole 21. The optical machine 30 is fixedly installed in the mounting hole 21. The frame body 40 is provided with a first mounting space and a second mounting space on the opposite sides. The frame body 40 is provided with a communication hole 41. When the optical machine 30 is fixedly assembled with the sleeve 20 in the first mounting space, the mounting hole 21 is arranged corresponding to the communication hole 41. The waveguide lens 10 is arranged corresponding to the communication hole 41 in the second mounting space.
[0034] The optical machine assembly structure of the embodiment of the present application, the waveguide lens 10 is fixedly assembled in the first mounting space, the sleeve 20 is fixedly assembled in the second mounting space, and the optical machine 30 is fixedly installed in the mounting hole. Therefore, the optical machine 30 can be fixedly assembled with the sleeve 20 in the first mounting space. Since the mounting hole 21 is arranged corresponding to the communication hole 41, the installed optical machine 30 can be arranged corresponding to the waveguide lens 10 through the communication hole 41. Therefore, the light emitting end 31 of the optical machine 30 can be directed to the waveguide lens 10, ensuring the effective transmission of the light output by the optical machine 30, avoiding interference or shielding of the image projected by the optical machine 30 to the waveguide.
[0035] In addition, since the first mounting space and the second mounting space are respectively located on the two sides of the frame body 40, the installed waveguide lens 10 and the sleeve 20 are also respectively located on the two sides of the frame body 40. The sleeve 20 and the waveguide lens 10 are separated by the frame body 40, which can avoid the pollution of the waveguide lens 10 caused by overflow during installation and fixation, and avoid interference or shielding of the image projected by the optical machine 30 to the waveguide.
[0036] As shown in Figure 1 and Figure 3As shown, in some embodiments, the sleeve 20 comprises a ring-shaped portion 23 and an outer peripheral portion 22 connected to each other, the ring-shaped portion 23 is provided with a mounting hole 21, and the radial dimension of the side of the light machine 30 facing the mounting hole 21 is slightly smaller than or equal to the radial dimension of the mounting hole 21 in the direction perpendicular to the mounting direction of the light machine 30. When the light machine 30 is mounted in the mounting hole 21, because the radial dimension of the side of the light machine 30 facing the mounting hole 21 is slightly smaller than or equal to the radial dimension of the mounting hole 21, the light machine 30 can enter the mounting hole 21 from the side of the mounting hole 21 away from the outer peripheral portion 22 to achieve stable assembly between the light machine 30 and the sleeve 20. Moreover, when the sleeve 20 is assembled, the outer peripheral portion 22 can be connected to the side surface of the frame body 40 located in the second mounting space, so as to ensure that the sleeve 20 can be stably assembled without falling into the communication hole 41, thereby ensuring that the light emitting end 31 of the light machine 30 can stably face the waveguide lens 10 and avoiding interference or shielding of the image projected by the light machine 30 to the waveguide.
[0037] As shown in the drawings, Figure 3 As shown, the outer peripheral portion 22 is located on the side of the end of the ring-shaped portion 23 facing the frame body 40.
[0038] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in some embodiments, the communication hole 41 is circular or circular-like, and the radial dimension of the communication hole 41 is greater than the radial dimension of the mounting hole 21 and less than the radial dimension of the outer peripheral portion 22 in the direction perpendicular to the mounting direction of the light machine 30. After the light machine 30 is assembled in the mounting hole 21, the radial dimension of the communication hole 41 is greater than the radial dimension of the light machine 30 in the direction perpendicular to the mounting direction of the light machine 30, so that the light emitted by the light emitting end 31 of the light machine 30 can enter the waveguide lens 10 through the communication hole 41 without being blocked by the frame body 40, thereby ensuring effective transmission of the light. In addition, when the sleeve 20 is assembled, because the radial dimension of the communication hole 41 is less than the radial dimension of the outer peripheral portion 22, the outer peripheral portion 22 can be connected to the side surface of the frame body 40 located in the second mounting space, so as to ensure that the sleeve 20 can be stably assembled without falling into the communication hole 41, thereby ensuring that the light emitting end 31 of the light machine 30 can stably face the waveguide lens 10 and avoiding interference or shielding of the image projected by the light machine 30 to the waveguide.
[0039] As shown in the drawings, Figure 1 and Figure 3As shown, in some embodiments, the optical engine 30 includes a main body 33 and a mounting portion 32 connected to the main body 33. In the mounting direction perpendicular to the optical engine 30, the radial dimension of the mounting portion 32 is larger than the radial dimension of the mounting hole 21. The mounting portion 32 can limit the mounting position of the optical engine 30 relative to the sleeve 20, ensuring accurate positioning of the optical engine 30 relative to the waveguide lens 10. Specifically, the portion of the main body 33 located on the side of the mounting portion 32 facing the light-emitting end 31 passes through the mounting hole 21.
[0040] For example, in the mounting direction perpendicular to the optical engine 30, the radial dimension of the mounting portion 32 is L1, and the radial dimension of the mounting hole 21 is L2, with 0.5mm ≤ L1 - L2 ≤ 8mm. This arrangement ensures that the mounting portion 32 of the optical engine 30 can be assembled inside the sleeve 20.
[0041] like Figure 3 As shown, in some embodiments, along the mounting direction of the optical engine 30, the vertical distance between the end of the main body 33 facing the connecting hole 41 and the mounting part 32 is less than the vertical distance between the end of the annular part 23 away from the connecting hole 41 and the side of the frame 40 away from the sleeve 20. After the optical engine 30 is assembled, the light-emitting end 31 of the optical engine 30 will not extend beyond the connecting hole 41 and will be placed on one side of the first mounting space of the frame 40, so that there is a gap between the light-emitting end 31 of the optical engine 30 and the waveguide lens 10, which can prevent the optical engine 30 from being too close to or pressing against the waveguide lens 10, thus preventing lens contamination or damage.
[0042] For example, along the mounting direction of the optical engine 30, the vertical distance between the end of the main body 33 facing the connecting hole 41 and the mounting part 32 is L3, and the vertical distance between the end of the annular part 23 away from the connecting hole 41 and the side of the frame 40 away from the sleeve 20 is L4, where 1mm ≤ L4 - L5 ≤ 10mm. This prevents contamination or damage to the waveguide lens 10 caused by the optical engine 30 being too close to or pressing against the waveguide lens 10.
[0043] like Figure 1 and Figure 3As shown, in some embodiments, the outer peripheral portion 22 is provided with a first dispensing surface 221 on one side of the frame body 40, and the outer peripheral portion 22 is fixedly installed on the frame body 40 through the first dispensing surface 221. When the sleeve 20 and the frame body 40 are fixedly installed, dispensing can be performed on the first dispensing surface 221, and then the outer peripheral portion 22 is attached to the frame body 40, so that the first dispensing surface 221 is attached to the frame body 40, and the sleeve 20 can be stably fixedly installed on the frame body 40. During installation, the overflow glue of the first dispensing surface 221 will flow along the contact surface between the sleeve 20 and the frame body 40, and may flow along the inner wall of the communication hole 41. On the one hand, since the sleeve 20 and the light machine 30 are both arranged on the side of the frame body 40 away from the waveguide lens 10, the glue will not directly contact the waveguide lens 10 during dispensing and assembly of the light machine 30 and the sleeve 20; on the other hand, since the frame body 10 itself has a certain thickness, and the communication hole 41 is arranged to have a radial size smaller than the radial size of the outer peripheral portion 22, so that the first dispensing surface 221 has a certain distance from the waveguide lens 10, that is, a larger accommodation space is formed between the light machine 30, the sleeve 20 and the frame body 40, and the excess glue will flow along the surface where the sleeve 20 contacts the frame 10, the communication hole 41 on the frame 40 to the edge area of the waveguide lens 10, and will not flow to the center area of the waveguide lens 10, so as not to interfere with or shield the image projected by the light machine 30 to the waveguide.
[0044] As shown in FIGS. Figure 1 and Figure 3 As shown, in some embodiments, the inner wall of the sleeve 20 is provided with a second dispensing surface 211, and the light machine 30 is fixedly installed in the mounting hole 21 through the second dispensing surface 211. In this embodiment, when the light machine 30 and the sleeve 20 are assembled, dispensing can be performed on the second dispensing surface 211, and then the light machine 30 is arranged in the mounting hole 21, so that the second dispensing surface 211 is attached to the outer wall of the light machine 30, and the light machine 30 can be stably installed on the sleeve 20. During installation, the overflow glue of the second dispensing surface 211 will flow along the contact surface between the hole wall of the mounting hole 21 and the outer wall of the light machine 30. Since the light machine 30 has a spacing from the waveguide lens 10 after installation, on the one hand, the glue flowing to the waveguide lens 10 can be reduced, and the glue contacting the waveguide lens 10 can be avoided to affect the waveguide lens 10; on the other hand, even if the glue flows to the position of the waveguide lens 10, it will only remain in the edge area of the waveguide lens 10, and will not flow to the center area of the waveguide lens 10, so as not to interfere with or shield the image projected by the light machine 30 to the waveguide.
[0045] The smart glasses of the embodiment of the application comprise a shell and an optical machine assembly structure. The shell is connected to one side of the frame body 40 and forms a second mounting space with the frame body 40, and the waveguide lens 10 is arranged in the mounting space. The waveguide lens 10 can be stably mounted in the second mounting space through the shell and the frame body 40, the mounting position of the waveguide lens 10 is stable and reliable, damage or pollution of the waveguide lens 10 caused by the assembly process of the optical machine 30 is reduced, and the image quality projected by the optical machine 30 on the waveguide lens 10 is improved.
[0046] The above is only the preferred embodiment of the application, and does not limit the patent scope of the application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like made by using the content of the specification and drawings within the application concept is included in the patent protection scope of the application.
