Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a smart pair of glasses. Background Technology

[0002] In related technologies, the basic structure of smart glasses includes temples and a lens body, which need to be electrically connected to achieve their function. To ensure the stability and reliability of the connection, this connection is usually designed to be non-detachable. However, considering users' personalized needs and convenience, some models now also have detachable connection modules on the temples, allowing users to replace the temples or change to different frames.

[0003] This solution does improve the user experience to some extent, but it also brings some problems. Because the detachable structure between the connecting module and the temple is often complex, difficulties may arise during assembly and disassembly. For example, users may need to spend considerable time and effort separating the connecting module from the temple when removing it. This not only increases the difficulty of operation but also negatively impacts the user experience. Summary of the Invention

[0010] Optionally, a boss is formed on the inner surface of the sliding cover facing the sliding groove and near the insertion groove at one end. A portion of the second plug is placed at the boss. A limiting groove is formed on the groove surface of the pillar facing the temple. The limiting groove is close to the insertion groove. When the sliding cover moves along the sliding groove toward the pillar, the boss and the limiting groove are engaged.

[0011] Optionally, the clearance groove and the leg protrusion are clearance-fitted; and / or, the electromagnet is located at the middle position of the upper and lower groove walls of the clearance groove.

[0012] Optionally, the ferromagnetic sheet is configured as a first permanent magnet, the first permanent magnet having the opposite magnetism to the electromagnet.

In use, the temple protrusion is inserted into the clearance groove, and the temple protrusion is magnetically fixed in a first position by the electromagnet and the ferromagnetic sheet, with the two temples parallel to each other, allowing the user to wear the glasses. Alternatively, the magnetic attraction of the electromagnet and the ferromagnetic sheet can be overcome, causing the two temples to fold closer to the frame, resulting in a second position for easy storage. Furthermore, the current to the electromagnet can be reduced or disconnected, reducing the magnetic attraction and making the frame and temples detachable for separate storage or replacement. By using a magnetic attraction method to detachably connect the frame and the two temples, the convenience of detaching and assembling the temples is improved, thereby enhancing the user experience, making the detachment and assembly process more convenient, and reducing the difficulty of user operation.

[0023] Explanation of icon numbers:

[0024] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0028] In today's technology market, smart glasses have become a popular wearable device. Smart glasses can be Augmented Reality (AR) products, or other popular wearable devices that meet daily communication needs while providing entertainment and leisure experiences. The basic structure of smart glasses includes temples and lenses, which require an electrical connection to function. To ensure the stability and reliability of the connection, this connection is usually designed to be non-detachable. However, considering users' personalized needs and convenience, detachable connection modules are now also available on the temples, allowing users to replace the temples or change to different frames.

[0029] This design philosophy does improve the user experience to some extent, but it also brings some problems. Because the detachable structure between the connecting module and the temples is often complex, difficulties may arise during assembly and disassembly. For example, users may need to spend considerable time and effort separating the connecting module from the temples when removing them. This not only increases the difficulty of operation but also negatively impacts the user experience to some extent.

[0030] To address this issue, the applicant is continuously exploring more optimized solutions. On the one hand, they are attempting to simplify the structure between the connecting module and the temples to reduce the complexity of disassembly and assembly; on the other hand, they are also committed to developing one-click or automated disassembly devices to improve the convenience for users to disassemble the temples.

[0031] In addition, the applicant also focused on the application of new materials. The aim is to improve the stability between the connecting module and the temple by using materials with higher elasticity and greater wear resistance, thereby further reducing wear during assembly and disassembly. Simultaneously, these new materials can also make the connecting module more detachable, thus meeting user needs.

[0032] In summary, current smart glasses still have certain problems with detachable connection design. To address this issue, this solution provides a smart glasses design that optimizes the detachable structure between the temples and the frame, improves the ease of temple assembly and disassembly, thereby enhancing the user experience, making the assembly and disassembly process more convenient, and reducing the difficulty of user operation.

[0033] Reference Figure 1 In one embodiment of the present invention, the smart glasses 100 includes: a lens body 200, two temples 300, and a connecting module 400. The lens body 200 includes a frame 210 and two pillars 220 extending from both sides of the frame 210 and in a direction away from the frame 210. The free ends of each pillar 220 are recessed into the frame 210 to form clearance grooves 221. Each temple 300 includes a temple protrusion 310, with one temple protrusion 310 inserted into a clearance groove 221. The connecting module 400 includes an electromagnet 410 and a ferromagnetic sheet 420 that magnetically attract each other. One of the temple protrusions 310 and the clearance groove 221 is provided... There is an electromagnet 410 and another is equipped with a ferromagnetic sheet 420; wherein, the head 220 and the temple 300 are magnetically attracted to each other through the connecting module 400, and the temple 300 can rotate relative to the head 220 to have a first position and a second position. In the first position, the two temples 300 are parallel to each other; in the second position, the two temples 300 are folded into the frame 210. It should be noted that the temples 300 are folded into the frame 210, that is, the temples 300 are stored, so that the two temples 300 are close to each other; the temples 300 can be at an angle with the head 220 at the hinge, such as 80°-100°; thereby facilitating the storage of the smart glasses 100.

[0034] In addition, when the magnetic attraction force of the connecting module 400 is less than the threshold, the frame 210 and the temple 300 can be completely separated and disassembled. For example, the magnetic force of the electromagnet 410 can be reduced by decreasing the current to the electromagnet 410, thereby making it easier for the temple 300 to separate from the frame 210. It is understood that when the connecting module 400 is demagnetized, the lens body 200 and the temple 300 can be completely separated and disassembled.

[0035] It should be noted that the threshold of magnetic attraction, that is, the magnitude of the fixing force between electromagnet 410 and ferromagnetic sheet 420, can be equivalent to the magnitude of the force required to separate electromagnet 410 and ferromagnetic sheet 420.

[0036] The lens body 200 and / or temple 300 may include a microphone, display optics, and external sensors such as conventional cameras and image capture cameras.

[0037] The temple 300 can rotate relative to the head 220. Taking the cylindrical electromagnet 410 and the ferromagnetic sheet 420 as an example, if the two ends of the cylindrical electromagnet 410 are vertical and the periphery of the ferromagnetic sheet 420 is in contact with the periphery of the cylindrical electromagnet 410, then the contact point is the rotation center line, and it can rotate around the rotation center line, which is left and right rotation.

[0038] If the two ends of the cylindrical electromagnet 410 are placed horizontally in the left-right direction, then the contact point between the ferromagnetic sheet 420 and the cylindrical electromagnet 410 is the rotation centerline, which can rotate vertically around the rotation centerline, and thus rotate up and down.

[0039] If the end face of the cylindrical electromagnet 410 is in contact with the end face of the ferromagnetic sheet 420, then the direction of the magnetic attraction of the ferromagnetic sheet 420 is the center line of rotation, which is also the direction of the axis of the cylinder.

[0040] The technical solution of this invention makes the lens body 200 and the lens body 200 easier to disassemble by connecting the module 400, meeting user needs. The connecting module includes an electromagnet 410 and a ferromagnetic sheet 420 that magnetically attract each other. One of the temple protrusions 310 and the clearance groove 221 is provided with an electromagnet 410, and the other is provided with a ferromagnetic sheet 420. In use, the temple protrusions 310 are inserted into the clearance groove 221, and the temple protrusions 310 are fixed in a first position by the magnetic attraction between the electromagnet 410 and the ferromagnetic sheet 420. The two temples 300 are parallel, and the user can wear them at this time; or overcome the electromagnetic interference. The magnetic attraction of the iron 410 and the ferromagnetic sheet 420 causes the two temples 300 to fold close to the frame 210. At this second position, the temples 300 are easy for the user to store. Furthermore, the current of the electromagnet 410 can be reduced or disconnected, reducing the magnetic attraction of the electromagnet 410. This allows the lens body 200 and the temples 300 to be detached and stored or replaced separately. By using a magnetic attraction method to detachably connect the lens body 200 and the two temples 300, the convenience of assembling and disassembling the temples 300 is improved, thereby enhancing the user experience, making the assembly and disassembly process more convenient, and reducing the difficulty of user operation.

[0041] It should be noted that, unlike the solution where the temple 300 is simply fixed to the lens body 200 by magnetic attraction, in this solution, the electromagnet 410 is magnetic when energized, and can attract and fix the ferromagnetic sheet 420. The electromagnet 410 and the ferromagnetic sheet 420 function as a pivot, and can also be fixed in a certain position; that is to say, the temple 300 can rotate relative to the lens body 200. The temple 300 can also be separated from the lens body 200. The separation of the temple 300 from the temple 200 can be achieved by reducing the current to the electromagnet 410 through the first circuit board 450 to reduce the magnetic force of the electromagnet, or by disconnecting the current to the electromagnet 410 to demagnetize the electromagnet 410. In other words, the electromagnet 410 can be set as a separate module or integrated with the main control board to control the current of the electromagnet 410, or to turn the electromagnet 410 on / off with a one-button operation.

[0042] In addition, ferromagnetic sheet 420 includes, but is not limited to, elements Fe, Co, Ni and their alloys, rare earth elements and their alloys, and some Mn compounds.

[0043] In one embodiment, an electromagnet 410 is disposed on the head 220, and the electromagnet is embedded vertically in the bottom of the relief groove 221, with the exposed portion being a semi-cylinder; a ferromagnetic sheet 420 surrounds the leg protrusion 310, and when the leg protrusion 310 is inserted into the relief groove 221, the ferromagnetic sheet 420 is attracted and fixed by the electromagnet 410; however, after overcoming a certain magnetic force, the temple 300 can rotate relative to each other.

[0044] In one embodiment, an electromagnet 410 is disposed on the temple 300.

[0045] Reference Figure 2 In one embodiment, the clearance groove 221 is provided with at least one electromagnet 410 on the upper and lower groove walls opposite to each other in the height direction of the frame 210, and the leg protrusion 310 is provided with a corresponding number of ferromagnetic sheets 420, and the ferromagnetic sheet 420 and the electromagnet 410 are magnetically attracted to each other.

[0046] Specifically, in order to ensure the temple 300 and the lens body 200 are fixed and stable and not easily detached, the ferromagnetic sheet 420 is configured as the first permanent magnet 421. The first permanent magnet 421 has the opposite magnetic properties to the electromagnet 410. The iron sheet is attracted to the electromagnet 410, resulting in a stronger fixing force. Furthermore, there is no need to increase the number of turns of the electromagnet 410 or adjust the current, which helps to reduce costs.

[0047] The mirror body 200 includes a frame 210 and two pillars 220 extending from both sides of the frame 210 and in a direction away from the frame 210. The free ends of the pillars 220 are recessed into the frame 210 to form relief grooves 221. Both temples 300 include temple protrusions 310. In use, one temple protrusion 310 is inserted into a relief groove 221. When the electromagnet 410 is energized, the two first permanent magnets 421 in the opposite directions of the upper and lower sides of the temple protrusion 310 are magnetically attracted and fixed by the two electromagnets 410 in the relief groove 221.

[0048] It should be noted that the first permanent magnet 421 on the same leg protrusion 310 has the same magnetism, and the two electromagnets 410 that cooperate with it have the same magnetism, but the first permanent magnet 421 and the electromagnets 410 have different magnetisms.

[0049] The magnetism of the first permanent magnet 421 on different protrusions 310 of the temple can be different. For example, the first permanent magnet 421 on the left temple 300 is the positive pole, and the electromagnet 410 that is matched with it is the negative pole; however, the first permanent magnet 421 on the right temple 300 can be either the positive pole or the negative pole. If it is the positive pole, then the electromagnet 410 that is matched with it is the negative pole; otherwise, the electromagnet 410 that is matched with it is the positive pole.

[0050] Reference Figure 3 and Figure 4 Specifically, the smart glasses 100 also includes a first circuit board 450 placed inside the frame 210, an electromagnet 410 disposed on the first circuit board 450, and the electromagnet 410 connected to the clearance groove 221.

[0051] The eyeglass frame 210 includes a front shell, a rear shell, and a first circuit board 450. The first circuit board 450 includes a control main board located at the bridge of the eyeglass frame 210, a left FPC and a right FPC located on both sides of the control main board, and an electromagnet 410 is provided in the vertical direction of the left FPC. The first circuit board 450 is placed between the front shell and the rear shell of the eyeglass frame 210. The electromagnets 410 are exposed from the clearance groove 221 formed on the pillar head 220 of the eyeglass frame 210. There are four electromagnets 410 and first permanent magnets 421 in total, two on the left and two on the right.

[0052] The first circuit board 450 can be the main control chip of the smart glasses, or it can be a control unit independent of the main control board. Specifically, the first circuit board 455 is a flexible board including two FPCs.

[0053] Specifically, such as Figure 4 In this embodiment, the left and right FPCs on both sides of the control motherboard are semi-circular, suitable for installation within the frame 210. Electromagnets 410 are respectively arranged on the left and right FPCs in opposite vertical directions. A first plug 451 is located between the two electromagnets 410. (Refer to...) Figure 5Two electromagnets are exposed from the clearance groove 221 formed by the column head 220.

[0054] Reference Figure 2 The smart glasses 100 also includes a switch button 470 electrically connected to the first circuit board 450, and the switch button 470 is located on the head 220.

[0055] The switch button 470 can control the opening of the circuit of the electromagnet 410 and / or also have the function of opening the first circuit board 450; the switch button 470 can be provided as one, located on the left column 220 or the right column 220; or two, located on the left column 220 and the right column 220 respectively.

[0056] In this embodiment, the switch button 470 is located above the head 220, that is, above the frame 210, so that the user can easily control the switch while wearing the glasses; without loss of generality, the switch button 470 can also be arranged on the outer side, inner side plate or bottom of the head 220.

[0057] The separation of temple 300 and temple 200 can be achieved by reducing the current flowing to electromagnet 410 through the first circuit board 450, thereby reducing the electromagnet's magnetic force. Specifically, for example, the switch button 470 can be a touch screen, allowing the user to select and adjust the function of electromagnet 410 via the touch screen, thereby reducing the magnetic attraction of electromagnet 410, which in turn reduces the current flowing to electromagnet 410; or the switch button 470 can be configured to correspond to different working modes based on the number of times / time of pressing, such as pressing twice quickly to reduce the magnetic attraction of electromagnet 410; or the separation of temple 300 and temple 200 can be achieved by disconnecting the current to electromagnet 410, thereby demagnetizing electromagnet 410, for example, by pressing the switch button 470 to directly disconnect or connect the current to electromagnet 410.

[0058] The first circuit board 450 is not only responsible for carrying and transmitting various signals, but also works in conjunction with other key components to realize the various functions of the smart glasses. To achieve magnetic control of the smart glasses 100, an electromagnet 410 is cleverly designed onto the first circuit board 450. The placement of the electromagnet 410 on the first circuit board 450 allows the smart glasses 100 to respond quickly when receiving user commands or external signals. Specifically, the first circuit board 450 reduces the magnetic force of the electromagnet 410 by reducing the current flowing to it. Furthermore, the electromagnet 410 can be instantly demagnetized by disconnecting the current. This facilitates the user's disassembly of the frame 210 and temples 300.

[0059] Reference Figure 5The basic structure of the smart glasses 100 includes temples 300 and glasses body 200. The two need to be electrically connected to realize their functions. Specifically, each of the pillars 220 is provided with a plug groove 222 facing the temples 300. The first circuit board 450 is also provided with a first plug 451, which is embedded in the plug groove 222.

[0060] Reference Figures 6 to 8 The smart glasses 100 also includes a second circuit board 460 and a second plug 461 electrically connected to the second circuit board 460. Each temple 300 is provided with a sliding groove 320 and a sliding cover 330 that slides with the sliding groove 320. The second circuit board 460 and the second plug 461 are both located in the sliding cover 330, or the second circuit board 460 is located inside the temple 300, and the second plug 461 passes through the temple 300 and is located in the sliding cover 330. In the first position, the sliding cover 330 moves along the sliding groove 320 toward the post 220, so that the first plug 451 and the second plug 461 are electrically connected. When the sliding cover 330 is moved so that the first plug 451 and the second plug 461 are disengaged, the two temples 300 can be rotated to the second position by external force.

[0061] Reference Figure 7 and Figure 8 The temple 300 includes an inner shell and an outer shell. During installation, the second circuit board 460 is fastened to the inner shell by four bolts. The inner shell has a wire hole. The second plug 461 passes through the wire hole and is placed in the slide groove 320. Then, the second plug 461 is fixed by a groove embedded in the inner side of the sliding cover 330. The sliding cover 330 can move relative to the slide groove 320, closer to or away from the frame 210. The first plug 451 is a female plug, exposed in the insertion slot 222 of the post head 220. The second plug 461 is a power plug, such as a frequency angle wire (the number of frequencies can be set as needed). In the first position, moving the sliding cover 330 makes the second plug 461 electrically connected to the first plug 451, realizing the electrical connection of the circuit boards between the temple 300 and the lens body 200 to achieve its function.

[0062] The temples 300 can rotate left and right, that is, rotate closer to the frame 210. The two temples 300 are folded into the frame 210. Because there is no wire restriction, the temples 300 can also move away from the frame 210. The temple protrusions 310 of the temples 300 are inserted into the relief grooves 221. The temple protrusions 310 and the temple 300 brackets have limiting steps. When the limiting steps abut against the pillar head 220, the temples 300 are limited and cannot rotate.

[0063] Understandably, when the sliding cover 330 connects the first plug 451 and the second plug 461, the temple 300 is fixed in the first position and cannot rotate relative to the mirror body 200.

[0064] Combination Figure 9and Figure 10 In the above scheme, after the first plug 451 and the second plug 461 are connected, the rotation limit of the temple 300 depends entirely on the connection between the first plug 451 and the second plug 461. If rotation occurs accidentally, the plugs are easily damaged. Therefore, in a further scheme, a boss 331 is formed on the inner surface of the sliding cover 330 facing the sliding groove 320 and close to the insertion groove 222. Part of the second plug 461 is placed at the boss 331. A limiting groove 223 is formed on the groove surface of the pillar 220 facing the temple 300. The limiting groove 223 is close to the insertion groove 222. When the sliding cover 330 moves along the sliding groove 320 toward the pillar 220, the boss 331 and the limiting groove 223 are engaged.

[0065] The outer side of the sliding cover 330 is provided with anti-slip stripes, which makes it easy for the user to push the sliding cover 330 to move along the sliding groove 320. When the sliding cover 330 is pushed close to the column head 220, the boss 331 will be inserted into the limiting groove 223. At this time, the second plug 461 will be inserted into the first plug 451. In this way, when the temple 300 and the lens body 200 rotate relative to each other, the boss 331 of the sliding cover 330 will be forced to block the movement of the temple 300, so as to avoid the connection between the first plug 451 and the second plug 461 being subjected to force.

[0066] Furthermore, the clearance groove 221 and the leg protrusion 310 are in clearance fit to control the gap between the leg protrusion 310 and the clearance groove 221, ensuring the fixing effect when magnetic.

[0067] Furthermore, the electromagnet 410 is positioned in the middle of the upper and lower walls of the clearance groove 221. The first permanent magnet 421 in the two temples 300 has polarity opposite to that of the electromagnet 410. When the temples 300 are placed into the clearance groove 221 of the head 220, the temple protrusions 310 are quickly attracted by the two electromagnets 410, and the attraction forces are the same. That is, each temple 300 is pulled evenly by a pair of equal attraction forces, and the temples 300 are necessarily in the center of the clearance groove 221. In this state, the two temples 300 cannot be easily pulled out, but can rotate around the axis of attraction. In addition, the temples 300 are fixed in the middle, which makes the fit between the temples 300 and the head 220 tighter during wearing, resulting in better overall quality of the smart glasses 100.

[0068] Reference Figures 9 to 11To facilitate the rotation of the temple 300 and reduce the force required by the user during the rotation, the smart glasses 100 also includes an elastic element 480, a second permanent magnet 430, and a third permanent magnet 440. The head 220 is also provided with a mounting groove 224 that communicates with the bottom of the relief groove 221 in the insertion direction. The elastic element 480 and the second permanent magnet 430 are sequentially arranged in the mounting groove 224, and the third permanent magnet 440 is arranged on the temple protrusion 310. During the rotation of the temple 300, when the second permanent magnet 430 and the third permanent magnet 440 approach each other, the second permanent magnet 430 and the third permanent magnet 440 are arranged with their magnetic poles facing each other.

[0069] During installation, the third permanent magnet 440 is inserted into the corresponding position from the inside front of the outer shell (it can be fixed with glue or other aids). The second permanent magnet 430 is placed into the corresponding fixing groove on the rear shell of the lens body 200. Then, the compression spring 510 is placed on it. Finally, the front shell of the lens body 200 is snapped onto the rear shell assembly of the lens body 200. The front shell and the rear shell of the lens body 200 can be connected by snaps.

[0070] In one embodiment, a third permanent magnet 440 is disposed on the side of the leg protrusion 310 near the frame 210.

[0071] In one embodiment, the included angle is 28°-60°.

[0072] In one embodiment, the third permanent magnet 440 is disposed on the side of the temple protrusion 310 near the frame 210, and when the temple 300 rotates to form a preset angle with the frame 210, the second permanent magnet 430 and the third permanent magnet 440 approach each other, and the preset angle is 28°-60°.

[0073] Reference Figures 9 to 11After the temple 300 and the lens body 200 are fixedly connected, the temple 300 can rotate between the wearing state and the storage state on its own rotation axis. During the rotation, the second permanent magnet 430 and the third permanent magnet 440 will gradually approach each other, reach their minimum value at 45 degrees and then gradually move away from each other. The repulsive force during the process also gradually increases, and the repulsive force is the greatest at the minimum distance at the 45-degree position, and then gradually decreases. However, the maximum repulsive force at the 45-degree angle is less than the attraction between the electromagnet 410 and the first permanent magnet 421. This ensures that the temple 300 can still be firmly connected to the lens body 200 during the rotation of the temple 300. When the temple 300 rotates to a 45-degree angle, the second permanent magnet 430 and the third permanent magnet are aligned, resulting in the greatest repulsive force and the maximum compression of the spring 510. At this position, the temple 300 does not generate any rotational force. However, once this angle is exceeded, the temple 300 will immediately be pushed and rotate around the rotation axis. That is, if the temple 300 rotates clockwise from the 45-degree angle, it will receive a push force for clockwise rotation. If the temple 300 rotates counterclockwise from the 45-degree angle, it will receive a push force for counterclockwise rotation.

[0074] Reference Figure 10 In the wearing mode, the stop platform of the lens body 200 and the stop platform of the temple 300 are in contact and engaged, that is, the temple 300 can no longer rotate to the left or right. At this time, the temple 300 is in a stable fixed state. When it is necessary to rotate the two temples 300 towards the center, it is only necessary to overcome the repulsive force of the second permanent magnet 430 and the third permanent magnet 440.

[0075] In the wearing mode, push the sliding cover 330 on the exterior of the two temples 300 so that the second plug 461 under the sliding cover 330 enters the lens body 200 and cooperates with the first plug 451. The protrusion 331 of the sliding cover 330 is inserted into the limiting groove 223 to ensure that the temples 300 cannot rotate around the axis at this time. At the same time, the connector plug connected to the circuit board inside the temples 300 is also inserted into the connector plug inside the lens body 200 that connects to the main board. After connection, the control board inside the temples 300 can be connected to the main board inside the lens body 200, thereby ensuring the realization of the functions inside the temples 300.

[0076] Reference Figure 9 and Figure 11After the sliding cover 330 is retracted into the temple 300, the temple 300 is rotated from the first position to the second position, which is the storage mode. When rotating from the first position to the second position, the second permanent magnet 430 and the third permanent magnet 440 repel each other and push the temple 300 to rotate clockwise around the rotation axis (opposite to the rotation direction in the wearing state). When the temple 300 is in contact with the frame 210, the inner shell sidewall of the temple 300 is tightly fitted with the stop platform on the lens body 200. Therefore, the temple 300 is also in a stable state in the storage state.

[0077] In addition, a specific shielding layer can be designed to avoid the effects of mutual interference between magnets.

[0078] This solution also allows the electromagnet 410 to be polarized or depolarized, or its magnetic attraction force to be reduced, via the switch button 470, thereby enabling the assembly or disassembly of the temple 300 and the lens body 200, thus providing users with a variety of user experiences.

[0079] After assembly, when the electromagnet 410 is turned on, the temple 300 can be held in the first and second positions, making installation and disassembly convenient.

[0080] To accommodate different users, this design allows for individual adjustment of the length of each temple by 300mm.

[0081] Furthermore, both the temples 300 and the frame 210 are made of carbon fiber; or, the temples 300 are made of a high-hardness, highly ductile metal. By using materials with higher elasticity and greater wear resistance, the stability between the frame 210 and the temples 300 can be improved, further reducing wear during assembly and disassembly. At the same time, this also allows for better detachability of the temples 300, thus meeting the needs of users.

[0082] Combination Figure 6 And refer to Figure 12 and Figure 13 Furthermore, the temple 300 includes a front temple 340, a rear temple 350, and a connecting member 500. The front temple 340 and the rear temple 350 are connected by the connecting member 500, and the rear temple 350 can move relative to the connecting member 500 away from the front temple 340.

[0083] In one embodiment, the connecting member 500 is built into the front leg member 340. The connecting member 500 has a claw and a pressing member that can move the claw when pressed. The outer shell of the rear leg member 350 has a slot. After the rear leg member 350 is embedded in the front leg member 340, the claw can engage with the slot. By engaging with the slot at different positions, the length of the temple 300 can be changed.

[0084] Reference Figure 12 and Figure 13 In another embodiment, the connecting member 500 includes a compression spring 510, an upper fork 520 and a lower fork 530 arranged in a cross configuration, with the compression spring 510 positioned between the upper fork 520 and the lower fork 530. The upper fork 520 and the lower fork 530 are provided with a connecting protrusion 531 and a positioning protrusion 532 with a height less than the connecting protrusion 531 in sequence along the extending direction. The front leg member 340 is provided with a connecting hole 341, and the rear leg member 350 is provided with at least two positioning holes 351 along the extending direction. The connecting protrusion 531 is engaged with the connecting hole 341 and partially extends out of the connecting hole 341. When the extended portion of the connecting protrusion 531 is pressed into the connecting hole 341, the positioning protrusion 532 can disengage from the positioning hole 351, and one of the positioning protrusions 532 can be selectively engaged with the positioning hole 351 to extend / shorten the temple 300.

[0085] In one embodiment, the upper fork 520 and lower fork 530, which are arranged in a cross configuration in the middle, can be hinged together at their tails, and the compression spring 510 is located between the upper fork 520 and the lower fork 530.

[0086] Reference Figure 12 and Figure 13 In one embodiment, the upper fork 520 and the lower fork 530 intersect, with the hinge at the middle position. The hinge is hollow, and the connecting member 500 is located inside the rear leg 350. The upper fork 520 and the lower fork 530 have hinge portions 540, and the rear leg 350 is correspondingly provided with a fixing portion 352. The hinge portion 540 is connected to the fixing portion 352.

[0087] Specifically, the upper fork 520 and the lower fork 530 extend along the hinge portion 540 to both ends to form a front end and a rear end. The insertion protrusion 531 and the positioning protrusion 532 are provided at the front end. The insertion protrusion 531 is located outside the rear leg 350. The compression spring 510 is provided at the rear end and is located inside the rear leg 350.

[0088] The front part of the rear leg piece 350 is provided with several positioning holes 351 along the extending direction, such as two, three, four, five, etc. Taking three positioning holes 351 as an example, the rear leg piece 350 can be inserted into the front leg piece 340. The rear leg piece 350 is fitted with a lower fork piece 530 and an upper fork piece 520. Both the upper fork piece 520 and the lower fork piece 530 are provided with a positioning protrusion 532. There are two insertion protrusions 531, located at the end of the upper fork piece 520 and the end of the lower fork piece 530, respectively. The length of the two insertion protrusions 531 is greater than the length of the positioning protrusions 532. The upper fork 520 and lower fork 530 are positioned outside the rear fork to prevent them from falling into the rear fork. The compression spring 510 allows the upper fork 520 and lower fork 530 to open, preventing them from detaching from the rear leg 350. Pressing the two insertion protrusions 531 inserts them into the front leg 340. When the insertion protrusions 531 move to the insertion holes 341, the compression spring 510 resets, causing the insertion protrusions 531 to extend out of the upper and lower insertion holes 341 respectively. The positioning protrusion 532 is located in the innermost positioning hole 351. At this time, the rear leg 350 is located inside the front leg 340.

[0089] Reference Figure 12 and Figure 13 When in use, to lengthen the temple 300, the insertion protrusion 531 can be pressed, and the upper fork 520 and lower fork 530 will come closer together through the hinge; the compression spring 510 will be compressed; because the height of the positioning protrusion 532 is less than the height of the insertion protrusion 531, the positioning protrusion 532 will disengage from the positioning hole 351, and the rear temple 350 is sleeved in the lower fork 530 and upper fork 520. By moving the rear temple 350, the positioning protrusion 532 will be inserted into the rear positioning hole 351, thereby changing the length of the temple 300.

[0090] In other designs, the positioning protrusion 532 and the insertion part can also be set separately on one side.

[0091] To prevent dust or moisture from entering the front leg 340 and affecting the second circuit board 460 inside the front leg 340, the connecting member 500 also includes a sealing ring 550 located between the front leg 340 and the rear leg 350.

[0092] In one embodiment, a sealing ring 550 is disposed on the rear leg 350, and when the rear leg 350 and the front leg 340 come close together, the sealing ring 550 is squeezed to achieve a seal.

[0093] In one embodiment, the sealing ring 550 is embedded in the cavity of the front leg member 340, and the portion of the rear leg member 350 inserted into the cavity of the front leg member 340 compresses the sealing ring 550, sealing the gap between the insertion points of the front leg member 340 and the rear leg member 350.

[0094] In summary, this solution utilizes two pairs of electromagnets 410 and permanent magnets with different positions and properties to achieve both easy assembly and disassembly of the temples 300 and stable placement of the temples 300 in several desired positions. The first position is the wearing position, ensuring relative stability between the lens body 200 and the temples 300. Based on this first position, the sliding cover 330 can be slid to ensure a secure connection between the temples 300 and the lens body 200 (preventing rotation of the temples 300) and to effectively connect the internal circuitry of the temples 300 with that of the lens body 200. The second position can store the smart glasses 100, and by demagnetizing the electromagnets 410 when the power is off, the temples 300 and the lens body 200 can be disassembled for flexible storage. Additionally, the length of each temple 300 can be adjusted individually by pressing the buttons on the temples 300 simultaneously. This solution is simple, practical, and suitable for mass production.

All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
