DETAILED DESCRIPTION

[0063] As mentioned in the background technology, augmented reality glasses (AR glasses for short) are designed to superimpose digital information on the user's real-world vision, thereby enhancing the user's visual experience. Among them, the optimization of the temple structure of AR glasses, the control of manufacturing costs and the improvement of user wearing experience all play an important role.

[0064] At present, the temples of AR glasses include an inner shell and an outer shell, which are bonded together through a glue dispensing process. However, the glue dispensing process is time-consuming, the process yield is low, and the bonded inner shell and outer shell are difficult to disassemble, and the maintenance convenience of the temples is poor.

[0065] In response to the above technical problems, an embodiment of the present application provides a kind of smart glasses, which can realize the snap connection between the temple shell and the shell cover through the setting of the snap-fit ​​structure, and realize the locking and unlocking of the shell cover by utilizing the relative position change of the self-locking mechanism set in the shell and the disassembly and assembly path of the shell cover, so that there is no need for gluing between the temple shell and the shell cover, which not only simplifies the assembly process of the temple of AR glasses, but also makes the disassembly and maintenance convenience of the shell and the shell cover improved. The disassembled shell and shell cover can be reused, saving costs. Moreover, the gluing process is eliminated, and the factory does not need to invest in related gluing equipment, thereby improving the production efficiency of AR glasses.

[0066] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0067] Combination Figures 1 to 15 The AR glasses provided by the embodiment of the present application include: a frame 100; a temple 200, including a shell 210, a clamping structure 220 and a shell cover 230, the shell 210 is rotatably connected to the frame 100, for example, the shell 210 is rotatably connected to the frame 100 through a rotating shaft mechanism 600, and the shell cover 230 is detachably connected to the shell 210 along a disassembly path through the clamping structure 220. When the shell cover 230 is fixedly connected to the shell 210, the shell cover 230 is in a In the first state, when the shell cover 230 is not fixedly connected to the shell body 210, the shell cover 230 is in the second state; the self-locking mechanism 300 is arranged in the inner cavity of the shell body 210, and the self-locking mechanism 300 is configured such that when the shell cover 230 is in the first state, the self-locking mechanism 300 is on the disassembly and assembly path of the shell cover 230 to lock the shell cover 230; when the shell cover 230 is in the second state, the self-locking mechanism 300 is not on the disassembly and assembly path of the shell cover 230 to unlock the shell cover 230.

[0068] Exemplarily, the shell 210 and the shell cover 230 are respectively provided with a first clamping portion and a second clamping portion, the shell cover 230 is movably clamped to the first clamping portion through the second clamping portion, and the shell cover 230 can slide relative to the shell 210 along its own length direction. At this time, the shell 210 is in the second state.

[0069] In this way, the shell 210 and the shell cover 230 can be snapped together through the setting of the snap-fit ​​structure 220, and the shell cover 230 can be locked and unlocked by utilizing the relative position change of the self-locking mechanism 300 set in the shell 210 and the disassembly and assembly path of the shell cover 230, so that there is no need for gluing between the shell 210 and the shell cover 230, which not only simplifies the assembly process of the AR glasses temple 200, but also improves the convenience of disassembly and maintenance of the shell 210 and the shell cover 230. The disassembled shell 210 and the shell cover 230 can be reused, saving costs. Moreover, the gluing process is eliminated, and the factory does not need to invest in related gluing equipment, thereby improving the production efficiency of AR glasses.

[0070] In some embodiments, the self-locking mechanism 300 is a deformable structure. When the self-locking mechanism 300 is before deformation, the angle between the self-locking mechanism 300 and the inner wall of the shell 210 is an acute angle. Exemplarily, the angle between the self-locking mechanism 300 and the inner wall of the shell 210 is 45 degrees, so that the self-locking mechanism 300 abuts against the shell cover 230 on the disassembly path; when the self-locking mechanism 300 is after deformation, the self-locking mechanism 300 is parallel to the inner wall of the shell 210, so that the self-locking mechanism 300 does not contact the shell cover 230 on the disassembly path.

[0071] In this way, it is only necessary to apply force to the deformable self-locking mechanism 300 to unlock the shell cover 230 and slide it out relative to the shell body 210, so as to complete the disassembly of the shell cover 230 relative to the shell body 210, thereby improving the problem of complicated assembly and gluing process of the temple 200, the shell body 210 and the shell cover 230. When the shell body 210 and the shell cover 230 are assembled, the shell cover 230 slides in from the end of the shell body 210 away from the frame 100, and the shell body 210 and the shell cover 230 are fixed by the snap-fit ​​structure 220. When the shell cover 230 is in the first state, the self-locking mechanism 300 at an acute angle to the inner wall of the shell body 210 is used to abut the shell cover 230 to lock it.

[0072] In some embodiments, the self-locking mechanism 300 includes a supporting portion 310 and an elastic portion 320, and the elastic portion 320 is connected to the inner wall of the shell 210 through the supporting portion 310. When the elastic portion 320 is before deformation, the angle between the elastic portion 320 and the inner wall of the shell 210 is an acute angle, so that the elastic portion 320 abuts against the shell cover 230 on the disassembly path; when the elastic portion 320 is after deformation, the elastic portion 320 is parallel to the inner wall of the shell 210, so that the elastic portion 320 does not contact the shell cover 230 on the disassembly path.

[0073] Exemplarily, the self-locking mechanism 300 is a metal spring sheet, which includes a connected supporting section and a warping section. The metal spring sheet can abut against the inner wall of the shell 210 through the supporting section. When the shell cover 230 is in the second state, that is, the shell cover 230 can slide from one end of the shell 210 to the other end, and the shell cover 230 presses the warping section to deform it and make it parallel to the inner wall of the shell 210. When the shell cover 230 slides to the first state, the warping section of the metal spring sheet rebounds and abuts against the shell cover 230 to limit the movement of the shell cover 230 along its own length direction, thereby completing the locking of the shell cover 230.

[0074] In some embodiments, the inner bottom wall of the shell 210 is provided with a limiting rib 211 , and the limiting rib 211 and the inner wall of the shell 210 form a limiting groove 212 , and at least part of the support part 310 is snapped into the limiting groove 212 to improve the supporting stability of the support part 310 .

[0075] Furthermore, the support portion 310 has a U-shaped elastic section, which elastically presses against the limiting groove 212 to improve the clamping stability of the support portion 310 and the limiting groove 212. Furthermore, the limiting rib 211 includes a first sub-rib and a second sub-rib that are connected. Along the length direction of the shell 210, the first sub-rib is fixedly connected to the inner wall of the shell 210 away from the side of the frame 100, and along the width direction of the shell 210, the extension direction of the second sub-rib intersects with the inner wall of the shell 210. In this way, two-way limitation of the support portion 310 along the length and width directions of the shell 210 is achieved, thereby improving the limiting stability of the support portion 310.

[0076] In some embodiments, the snap-on structure 220 includes a protrusion 221 and a rib plate 222, the protrusion 221 is fixed to the inner wall of the shell 210, the rib plate 222 is fixedly connected to the shell cover 230, the rib plate 222 has a snap-on 2221, and illustratively, the cross-sectional shape of the rib plate 222 is L-shaped, the L-shaped rib plate 222 is fixed to the surface of the shell cover 230 facing the shell 210, and the L-shaped rib plate 222 extends along the length direction of the shell cover 230, the L-shaped rib plate 222 and the surface of the shell cover 230 constitute a snap-on 2221, and when the shell cover 230 is in the first state, the protrusion 221 is snap-on to the snap-on 2221.

[0077] In this way, by setting the soil blocks and rib plates 222 on the shell body 210 and the shell cover 230, the two can be snap-fitted to achieve the limited fixation of the shell cover 230 along its own thickness and width directions.

[0078] In some embodiments, there are at least two protrusions 221. Along the length direction of the shell 210, the two protrusions 221 are fixed at intervals on an inner wall of the shell 210. Furthermore, there may be three protrusions 221. In this way, the connection stability between the shell cover 230 and the shell 210 in the first state, i.e., the locked state, is enhanced.

[0079] In some embodiments, there are two ribs 222, and along the width direction of the shell cover 230, the two ribs 222 are fixed to the shell cover 230 at intervals, and the two ribs 222 both have a snap-on 2221; along the width direction of the shell 210, at least two protrusions 221 are fixed to the two opposite inner walls of the shell 210, and the two protrusions 221 are respectively snap-connected with the two snap-ons 2221.

[0080] In some embodiments, the shell cover 230 is further provided with reinforcing ribs 231 , which are connected between the two rib plates 222 . The reinforcing ribs 231 and the plates 222 are vertically arranged on the surface of the shell cover 230 and are orthogonally connected to the two rib plates 222 to further support the rib plates 222 .

[0081] In some embodiments, an electronic cable 400 is also included, and the electronic cable 400 is arranged in the inner cavity of the shell 210; the bottom wall of the inner cavity of the shell 210 is provided with a limit plate 213, and when the shell cover 230 is in the first state, there is an avoidance gap between the reinforcing rib 231 and the limit plate 213, and the electronic cable 400 passes through the avoidance gap and extends from the side of the shell 210 close to the frame 100 to the other side of the shell 210. In this way, through structural design, the routing layout of the electronic cable 400 between the shell 210 and the shell cover 230 is optimized, and the structural compactness inside the temple 200 is improved.

[0082] In some embodiments, a flexible seal 500 is fixed to the portion of the electronic cable 400 located in the avoidance gap. When the shell cover 230 is in the first state, the flexible seal 500 seals and connects the electronic cable 400 and the reinforcing rib 231. Exemplarily, the flexible seal 500 is a sealing foam, which is bonded to the reinforcing rib 231. In this way, not only is the sealing of the electronic cable 400 in the shell 210 enhanced, and foreign matter such as water and / or dust can be prevented from entering the inside of the temple 200 from the outside, thereby protecting the electronic cable 400 and functional components such as the battery 700 inside the shell 210, but the flexible foam also reduces its contact force with the electronic cable 400, thereby providing structural protection for the electronic cable 400.

[0083] In more embodiments, the AR glasses also include a battery 700, a circuit board 800 and a speaker module installed in the shell 210, wherein the battery 700 is electrically connected to the electronic cable 400 to power the electronic components in the AR glasses; the circuit board 800 is used for the transmission and functional integration of electrical signals in the AR glasses, and the speaker module is used to convert digital audio signals into sound waves so that the user can hear the voice commands generated by the device.
