[0035] Figure 1 This is a schematic diagram of smart glasses according to an embodiment of this application.
[0036] refer to Figure 1 The smart glasses 1000 includes temples 1100, a frame 1200, and lenses 1300. The frame 1200 includes a post 1210 for hinged connection with the temples 1100. Furthermore, at least one camera 1220 may be disposed on the frame 1200. According to another embodiment of this application, at least one microphone and at least one speaker may also be disposed on the temples 1100 for voice interaction between the user and the smart glasses 1000. Additionally, at least one bone conduction earphone may be disposed at the nose pad of the frame 1200 to enhance the acquisition of the user's voice input signal.
[0037] Figure 2 This is a schematic diagram of the temple structure of smart glasses according to an embodiment of this application. (Reference) Figure 2 The temple 1100 includes a temple housing 1110. The temple housing 1110 can be made of materials such as plastic, resin, carbon fiber, or alloy. The temple housing 1110 can be formed by fastening together a front temple cover and a rear temple cover. Various sensors (e.g., microphones) or audio output devices (e.g., speakers, bone conduction devices) can be housed inside the temple housing 1110. The sensors and audio output devices, among other electronic components, can be integrated onto a flexible printed circuit board (FPC) protected by the temple housing 1110. The temple 1100 is hinged to a post 1210 to allow for the unfolding and folding of the temple 1100.
[0038] Figure 3 This is a schematic diagram of an eyeglass temple assembly 2000 according to an embodiment of this application. Figure 4This is a schematic diagram of a spring box 2400 according to an embodiment of this application. The temple assembly 2000 includes a base 2100. The base 2100 is fixedly connected to the post 1210 of the smart glasses 1000. The base 2100 includes a pin hole 2110. The pin hole 2110 is used to insert a pin 2300. The pin 2300 is used to connect the spring connector 2200 to the base 2100 to achieve folding and unfolding of the temples. The spring connector 2200 includes a first connecting arm 2210, a second connecting arm 2220, and a spring baffle 2230 positioned between the two connecting arms. The first connecting arm 2210 and the second connecting arm 2220 each have a connecting hole for inserting the pin 2300.
[0039] To clearly illustrate the spring structure, Figure 3 The spring 2440 is in its naturally extended state. However, it should be understood that during operation, the upper edge of the spring 2440 will be confined below the spring baffle 2230.
[0040] like Figure 4 As shown, the temple assembly 2000 also includes a spring box 2400 confined within the spring-loaded connector 2200. The spring box 2400 includes a first wall 2410 mating with the first connecting arm 2210 and a second wall 2420 mating with the second connecting arm 2220. The spring box 2400 also includes a spring hole 2430 for receiving at least one spring 2440. The spring hole 2430 is a blind hole structure, thereby supporting the bottom of the spring 2440. Figure 4 In the embodiment shown, the spring box 2400 includes two compression springs side by side.
[0041] It should be noted that the second wall 2420 includes a recessed structure 2421 that matches the second connecting arm 2220. The recessed structure 2421 can limit the vertical movement of the spring box 2400 (and the spring 2440) and also serve as a foolproof mechanism to prevent incorrect installation.
[0042] In the working state, the spring 2440 protrudes from the top of the spring hole 2430 and abuts against the spring baffle 2230. As the spring-loaded connector 2200 rotates around the pin 2300, the spring box 2400 and the spring 2440 inside the spring box 2400 move up and down inside the spring-loaded connector 2200.
[0043] The temple assembly 2000 may also include a flexible circuit board baffle 2500, which can cover the FPC inside the temple assembly to prevent the FPC from being exposed.
[0044] The bottom of the base 2100 is fixedly connected to the pile head 1210, for example, by adhesive bonding. The base 2100 may include alternating concave and convex structures 2110, which can increase its contact area with the pile head 1210 and increase the strength of the adhesive bonding.
[0045] According to the structure of the temple assembly provided in this application, the post 1210 is only fixedly connected to the base 2100, while the elastic components, including the spring connector 2200 and the spring box 2400, are all located on the side closer to the temple 1100 rather than on the side of the post 1210. Therefore, a low-post eyeglass design can be achieved, making the shape of the smart glasses 1000 closer to that of ordinary glasses, and enabling various fashionable eyeglass designs.
[0046] Figure 5 This is a side view of base 2100. (Reference) Figure 5 The distance from the pin hole 2110 to the inner edge of the base is L1, and the distance from the pin hole 2110 to the upper edge of the base is L2. When the temple 1100 is in the folded state, the spring-loaded connector 2200 is approximately horizontal. At this time, the degree of compression of the spring 2440 is determined by L1, and the degree of compression is relatively low. When the user unfolds the temple 1100, the spring 2440 is further compressed. The spring 2440 is compressed to its maximum extent until the temple 1100 is unfolded to the diagonal position of the quadrilateral formed by L1 and L2. If the user stops unfolding the temple 1100 before it reaches this position, the temple 1100 tends to return to the folded state under the action of the elastic force. When the user extends the temples 1100 beyond the diagonal of the quadrilateral formed by L1 and L2, the compression of spring 2440 decreases as the user continues to extend the temples 1100 until they are fully extended. In the fully extended state, the spring-loaded connector 2200 is approximately vertical, and the compression of spring 2440, determined by L2, is relatively low. Therefore, in the final stage of extending the temples 1100, the spring force of spring 2440 generates a feedback force that tends to extend the temples, thus improving the user experience.
[0047] If the user continues to extend the temples 1100 outwards, the spring 2440 becomes more compressed compared to when the temples 1100 are fully extended. Therefore, under the restoring force of the spring 2440, the temples 1100 will generate a force that tends to return to a vertical position. This force manifests as a clamping force between the temples 1100 and the user's head, thereby improving the stability of the user wearing the glasses. Although the temples 1100 can extend outwards to a certain angle, this angle is usually limited to a reasonable range, such as 10 degrees.
[0048] Continue to refer to Figure 5 According to the embodiments of this application, the radius R1 of the inner edge of the base 2100 is greater than the radius R2 of the outer edge of the base 2100. With this configuration, when the temples 1100 fold inward, the arc of movement is relatively gentle, reducing the likelihood of bumps or knocks.
[0049] Figure 6 This is a schematic diagram of the flexible circuit board 2700 of the eyeglass temple assembly 2000. (Reference) Figure 6 The temple assembly 2000 includes a flexible circuit board 2700. As described above, various electronic devices, including but not limited to microphones, speakers, and bone conduction headphones, can be disposed inside the temple 1100. These electronic devices can be integrated onto the flexible circuit board 2700. Furthermore, various electronic components, including but not limited to cameras, displays, and bone conduction microphones, can also be disposed on the eyeglass frame 1200. For this purpose, the flexible circuit board 2700 extends through the base 2100 inside the temple assembly 2000 and is electrically connected to the electronic components of the eyeglass frame 1200. As described above, a flexible circuit board baffle 2500 covers the flexible circuit board 2700 near the post pin 2300 to provide protection for it.
[0050] The temple assembly 2000 may further include a spring housing 2600. The spring housing 2600 encloses the spring box 2400 and the spring connector 2200. The spring housing 2600 serves to limit the movement of internal components and also increases structural strength. The spring housing 2600 is fixedly connected to the temple housing (not shown) and the spring connector 2200 by screws 2800. According to an embodiment of this application, the position of the screws 2800 can correspond to... Figure 4 The recessed portion of the concave structure 2421 shown (i.e., the upper half of the second wall 2420 of the spring box).
[0051] According to the embodiments of this application, the structure of the spring box can have various variations. Figure 7 and Figure 8 Alternative implementations of the spring box are shown.
[0052] refer to Figure 7 The spring box 7000 may include a spring hole 7100 and a guide pin 7200. A spring can be inserted between the spring hole 7100 and the guide pin 7200. The guide pin 7200 further enhances the positioning and guidance of the spring, improving the directional stability of the spring's extension and contraction.
[0053] refer to Figure 8The spring box 8000 may consist only of the guide pin 8100. The spring can be fitted onto the outside of the guide pin 8100 and move up and down under the guidance of the guide pin 8100. In this case, the structure of the spring box is further simplified, and the overall weight of the smart glasses can be further reduced.
[0054] According to the embodiments of this application, the shape of the spring connector and its connection method with the temple shell can also have various variations. Figure 9 , Figure 10 and Figure 11 Alternative implementations of the eyeglass temple assembly are shown.
[0055] Although Figure 4 and Figure 6 As shown, the temple housing, spring connector, and spring box can be connected using only one screw (2800), but reference... Figure 9 Alternatively, the first screw 9810 and the second screw 9820 can be used to connect the temple housing (not shown), the spring connector 9200, and the spring box (not shown) respectively, thereby improving the structural strength. The first screw 9810 can correspond to the recessed portion of the concave structure of the spring connector 9200 and the spring box 9300.
[0056] refer to Figure 10 The two connecting arms of the spring-loaded connector can also be symmetrical. Correspondingly, the recessed structure of the spring box can be omitted. In this case, the temple housing, the spring-loaded connector 10200, and the spring box can be connected by only one screw 10100.
[0057] refer to Figure 11 When the two connecting arms of the spring connector are symmetrical, two screws—namely, the third screw 11010 and the fourth screw 11020—can also be used to connect the temple shell, the spring connector, and the spring box.
[0058] The above description is merely an illustration of the embodiments of this application and the technical principles employed. Those skilled in the art should understand that the scope of protection involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the described technical concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
