Headset fixture and headset storage case

Abstract

The head-mounted device fixing device and the head-mounted device storage box are disclosed, and the positioning part is arranged on the first elastic part to drive the positioning head to be close to or away from the nose bridge groove through the first elastic part. Thus, when the smart glasses are installed, the positioning head can avoid the nose bridge to facilitate the insertion of the nose bridge into the nose bridge groove. When the nose bridge is in place, the positioning head is in abutment with the nose bridge under the driving of the first elastic part to fix the nose bridge, thereby simplifying the operation mode of the head-mounted device fixing device and facilitating the fixing and taking out of the smart glasses. On the other hand, the positioning head is configured to protrude from the side where the first limiting side surface of the nose bridge groove is arranged, so that the positioning head can avoid the nose pad and the leg when fixed, thereby improving the adaptability of the head-mounted device fixing device to different types of smart glasses.

Detailed Implementation

[0027] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0028] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0029] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0030] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0031] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “below” another element or feature would then be positioned “above” that other element or feature. Thus, the exemplified term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

Figure 2 This is an exploded view of one side of the head-mounted device storage box in this embodiment. Figure 2 Only a portion of the protective section 6 is shown in the image. Figure 3 This is an exploded schematic diagram of the head-mounted device fixing device 7 in this embodiment.

[0034] In some implementations, such as Figures 1-2 As shown, the head-mounted device storage case includes a head-mounted device fixing device 7 and a protective part 6. The head-mounted device fixing device 7 is fixedly connected to the inner wall of the protective part 6. The head-mounted device fixing device 7 is used to fix the head-mounted device, and the protective part 6 is used to accommodate the head-mounted device and protect it. Further referencing... Figure 3 As shown, the head-mounted device fixing device 7 includes a mounting frame 1 and a positioning component 2.

[0035] Figure 4 and Figure 5 This is a schematic diagram of the structure of the smart glasses A in this embodiment.

[0036] Optionally, the head-mounted device can be smart glasses A or ordinary glasses. The smart glasses A can be used to achieve functions such as virtual reality, augmented reality, or audio playback. Further reference... Figures 4-5 As shown, smart glasses A includes two frames A2 and a bridge A1 connecting the two frames A2. Ordinary glasses can be framed glasses. The following explanation uses smart glasses A as an example.

[0037] Figures 6-9 The structure of the head-mounted device fixing device 7 provided in the first embodiment is shown. Figure 6 and Figure 7 This is a partial schematic diagram of the head-mounted device fixing device 7 provided in the first embodiment. Figure 8 and Figure 9 This is an exploded view of the mounting bracket 1, positioning component 2, and adjustment component 4 provided in the first embodiment.

[0038] Figures 10-13 The structure of the mounting bracket 1 and positioning component 2 provided in the second embodiment is shown. The mounting bracket 1, charging component 3, and adjustment component 4 of the second embodiment can be configured similarly to those of the first embodiment, and will not be shown in detail here. Figure 10 This is a schematic diagram of the structure of the mounting bracket 1 and the positioning component 2 provided in the second embodiment. Figure 11 and Figure 12 This is an exploded view of the mounting bracket 1 and positioning component 2 provided in the second embodiment. Figure 13 yes Figure 10 A partial cross-sectional view at point AA.

[0039] In some implementations, such as Figure 6 , Figure 8 and Figure 9 As shown, the mounting bracket 1 is provided with a nose bridge groove 11. The nose bridge groove 11 is provided with a limiting bottom surface 113 and a first limiting side surface 111. In this embodiment, the nose bridge groove 11 is used to set the nose bridge A1 of the smart glasses A. The smart glasses A can be snapped into the nose bridge groove 11 through the nose bridge A1.

[0040] Further reference Figures 6-7 and Figures 10-11 As shown, the positioning component 2 includes a first elastic portion 21 and a positioning portion 22 disposed on the first elastic portion 21. The positioning portion 22 includes a positioning head 221. The nose bridge groove 11 is recessed in a direction away from the positioning portion 22, that is, the nose bridge groove 11 is recessed downwards from the positioning portion 22 (at this time, the mounting bracket 1 is in the position of...). Figure 6 and Figure 10 (as shown in the diagram). Furthermore, the positioning head 221 extends to one side of the nose bridge groove 11 where the first limiting side 111 is provided.

[0041] Optionally, the number of positioning heads 221 can be one, two, three, or more. For example, when there is only one positioning head 221, it can be positioned directly above the nose bridge groove 11 (at this time, the mounting bracket 1 is in position). Figure 6 and Figure 10 (The location shown in the image).

[0042] The positioning head 221 moves toward the side of the nose bridge groove 11 away from the first limiting side 111, that is, in the first direction (e.g. Figure 7 and Figure 10 As shown by arrow a1 in the diagram, the first elastic part 21 generates a restoring elastic force.

[0043] Specifically, when the nose bridge A1 is inserted from above the nose bridge groove 11, the bottom of the nose bridge A1 can contact the positioning head 221, so as to push the positioning head 221 away from the nose bridge groove 11 during the downward movement, thereby achieving the positioning head 221 avoiding the nose bridge A1. Alternatively, the user can directly press the positioning head 221 to make the positioning head 221 move away from the nose bridge groove 11. During this process, the positioning part 22 can compress the first elastic part 21.

[0044] Driven by the reset elastic force of the first elastic part 21, when the positioning head 221 moves a predetermined distance toward the side of the nose bridge groove 11 where the first limiting side 111 is located (that is, in the second direction opposite to the first direction), a nose bridge limiting space 12 is formed between the positioning head 221 and the nose bridge groove 11. In this configuration, the positioning head 221 can cooperate with the nose bridge groove 11 to clamp the nose bridge A1, so that the smart glasses A will not easily shake within the protective part 6.

[0045] Optionally, the positioning part 22 can cooperate with different areas of the bridge of the nose A1. When the positioning head 221 and the bridge groove 11 form the bridge limiting space 12, the positioning head 221 can abut against the side of the bridge of the nose A1 away from the temple A3 (e.g. Figure 4 (As shown in region IVa). In this configuration, the positioning head 221 can push the bridge of the nose A1 against the first limiting side 111, so that the bridge of the nose A1 is held between the positioning head 221 and the first limiting side 111. Alternatively, the positioning head 221 can abut against the top of the bridge of the nose A1 (as shown in region IVa). Figure 4 As shown in region IVb), in this configuration, the positioning head 221 can press the bridge of the nose A1 down to the limiting bottom surface 113 to fix the bridge of the nose A1.

[0046] It's easy to understand that a nose bridge (such as a nose pad) can be placed on the inside of the bridge of the nose (A1). Figure 5 (As shown in the position of region IVc), the nose pad structure varies depending on the type of smart glasses A. Furthermore, when the smart glasses A are placed inside the protective part 6, the two temples A3 fold inwards. In this configuration, by using the fixing method between the positioning head 221 and the nose bridge groove 11, interference between the positioning head 221 and the nose pad or temples A3 can be avoided, improving the adaptability of the head-mounted device fixing device 7.

[0047] In summary, the head-mounted device fixing device 7 in this embodiment has a positioning part 22 disposed on the first elastic part 21, so that the positioning head 221 is driven by the first elastic part 21 to move closer to or away from the nose bridge groove 11. Therefore, when installing the smart glasses A, the positioning head 221 can avoid the nose bridge A1, so that the nose bridge A1 can be inserted into the nose bridge groove 11. When the nose bridge A1 is in place, driven by the first elastic part 21, the positioning head 221 abuts against the nose bridge A1 to fix the nose bridge A1. This simplifies the operation of the head-mounted device fixing device and facilitates the fixing and removal of the smart glasses A. On the other hand, configuring the positioning head 221 to extend towards the side of the nose bridge groove 11 where the first limiting side 111 is provided allows the positioning head 221 to avoid the nose pad and temple A3 during fixing, improving the adaptability of the head-mounted device fixing device 7 to different types of smart glasses A.

[0048] In some implementations, such as Figure 6 and Figure 10 As shown, there are two positioning heads 221. The two positioning heads 221 are arranged at intervals along the extension direction of the nose bridge groove 11, and in the extension direction of the nose bridge groove 11 (e.g., Figure 6 As shown by arrow a2 in the diagram, the nose bridge groove 11 is located between the two positioning heads 221. Therefore, in the cross-sectional direction perpendicular to the width direction of the nose bridge groove 11 (as shown by arrow a2 in the diagram), the nose bridge groove 11 is positioned between the two positioning heads 221. Figure 10As shown by the middle arrow a1, in this embodiment, the two positioning heads 221 and the nose bridge groove 11 form a three-point positioning structure in space, which improves the fixing strength of the head-mounted device fixing device 7 to the nose bridge A1 and reduces the occurrence of the smart glasses A shaking in the nose bridge groove 11.

[0049] In some implementations, such as Figure 6 , Figure 10 and Figure 11 As shown, the nose bridge groove 11 is also provided with a second limiting side 112, which is spaced apart from and opposite to the first limiting side 111. One side of the first limiting side 111 is connected to the limiting bottom surface 113, and the other side is inclined away from the second limiting side 112.

[0050] Specifically, in this embodiment, the first limiting side 111, the second limiting side 112, and the limiting bottom surface 113 are all contoured surfaces. The contours of the contoured surfaces are configured to fit the rear, bottom, and front surfaces of the nose bridge A1, so that the nose bridge A1 is more stable on the mounting bracket 1.

[0051] Figure 14 This is a schematic diagram of the working process of the head-mounted device fixing device 7 according to an embodiment of the present invention. The outline of the mounting frame 1 is shown with a thick solid line, and the outline of the first housing 322 is shown with a dashed line. States I, II, and III in the figure respectively show the different positions of the mounting frame 1 during movement. The thick dashed line Ia represents the position of the outer edge of the retaining wall 1322 in state I. The figure also shows the nose bridge A1 in… Figure 4 The profile along the cutting direction shown in BB.

[0052] Further reference Figure 12 As shown in state I, the first limiting side 111 in this embodiment is inclined, which increases the opening angle of the top of the nose bridge groove 11 (as shown by the included angle b1 in the figure). This helps the user to smoothly insert the nose bridge A1 into the nose bridge groove 11, reducing the time required to adjust the angle of the smart glasses A. In addition, it increases the space of the nose bridge groove 11. When the positioning head 221 pushes against the nose bridge A1, the nose bridge A1 will abut against the first limiting side 111 and the limiting bottom surface 113. In this configuration, even if the width and height of different nose bridges A1 vary, the first elastic part 21 can adjust the movement range of the positioning part 22 to change the size of the nose bridge limiting space 12, thereby improving the adaptability of the head-mounted device fixing device 7.

[0053] In some implementations, such as Figure 8 , Figure 11 and Figure 14As shown, the positioning head 221 has a first positioning surface 2211. The first positioning surface 2211 is located on the side of the positioning head 221 facing the nose bridge groove 11. Furthermore, the side of the first positioning surface 2211 near the limiting bottom surface 113 is inclined away from the first limiting side surface 111. A nose bridge limiting space 12 is formed between the first positioning surface 2211 and the nose bridge groove 11. In addition, the first positioning surface 2211 can be configured to move a portion of its area to a position opposite to the limiting bottom surface 113.

[0054] In this embodiment, the first positioning surface 2211 can abut against the top of the nose bridge A1, driving the nose bridge A1 to abut against the limiting bottom surface 113 and the first limiting side surface 111. Thus, in the cross-sectional direction perpendicular to the extending direction of the nose bridge groove 11 (e.g., ... Figure 14 As shown, the first positioning surface 2211, the limiting bottom surface 113, and the first limiting side surface 111 can also form another three-point positioning structure, thereby further increasing the stability of the smart glasses A.

[0055] In some implementations, such as Figure 3 and Figure 9 As shown, the head-mounted device fixing device 7 also includes a charging assembly 3. The charging assembly 3 includes an energy storage section 33, a housing section 32, and a power supply section 31. The power supply section includes a power supply contact 311, which is disposed on the mounting bracket 1. The energy storage section 33 is disposed inside the housing section 32 and electrically connected to the power supply section 31. The housing section 32 includes a connection window 321, and the mounting bracket 1 is movably disposed on the connection window 321.

[0056] Optionally, the energy storage unit 33 can be a battery. The power supply contact 311 can be located at the first limiting side 111, the nose bridge limiting space 12, or the second limiting side 112, etc., and can be adjusted by those skilled in the art according to the position of the connection contact of the smart glasses A. Thus, when the smart glasses A is placed on the head-mounted device fixing device 7, the power supply contact 311 abuts against the connection contact to realize the charging function of the head-mounted device fixing device 7 for the smart glasses A.

[0057] In some implementations, such as Figures 6-8 As shown, the positioning component 2 includes a second fixing part 2b. The second fixing part 2b includes a first elastic part 21 and a positioning part 22. The positioning part 22 is a flexible member and includes two positioning heads 221. The first elastic part 21 is an elastic sheet 211. Further referencing... Figure 9 As shown, the elastic sheet 211 includes a fixed section 2111 and a driving section 2112 in its extending direction. The positioning part 22 is disposed on the driving section 2112, and the fixed section 2111 is fixedly connected to the mounting bracket 1. When the positioning part 22 moves away from the nose bridge groove 11, the elastic sheet 211 undergoes bending deformation in a direction perpendicular to its own plane. Thus, the two positioning heads 221 move synchronously.

[0058] Optionally, the positioning part 22 can be made of elastic material such as rubber or foam to prevent the positioning head 221 from damaging the bridge of the nose A1. During injection molding, the driving section 2112 can be set as an insert inside the cavity to fix the positioning part 22 and the driving section 2112 through insert molding technology.

[0059] Optionally, such as Figure 8 As shown, the positioning head 221 is provided with a second guide surface 2213. The side of the second guide surface 2213 closest to the first limiting side 111 is inclined toward the limiting bottom surface 113. When the nose bridge A1 is pressed into the nose bridge groove 11, the bottom of the nose bridge A1 abuts against the second guide surface 2213, which can push the positioning part 22 away from the nose bridge A1.

[0060] In some implementations, such as Figures 10-12 As shown, the positioning component 2 includes a first fixing part 2a. The first fixing part 2a includes a first elastic part 21, a positioning part 22, and a fixing seat 23. The fixing seat 23 is disposed on the mounting bracket 1. One end of the first elastic part 21 abuts against the fixing seat 23, and the other end abuts against the positioning part 22. The positioning head 221 is formed on the side of the positioning part 22 away from the first elastic part 21.

[0061] Optionally, in this embodiment, the positioning component 2 includes two first elastic parts 21, two positioning parts 22, and a fixing seat 23. The first elastic parts 21 are configured as compression springs, with one side of each spring simultaneously abutting against the fixing seat 23, and the other side simultaneously pushing the positioning head 221 closer to the nose bridge groove 11. This allows the two positioning heads 221 to move independently, enabling the user to tilt the nose bridge A1 and insert it into the nose bridge groove 11, thus allowing the two positioning heads 221 to move separately and reducing the downward pressure during insertion.

[0062] In some implementations, such as Figures 10-12 As shown, the first fixing part 2a further includes a positioning sleeve 24, one end of which is provided with a positioning port 241. The positioning part 22 further includes a guide post 222, and a positioning head 221 protrudes from one end of the guide post 222. The guide post 222 is provided with a receiving hole 2221 and a second positioning surface 2222, the second positioning surface 2222 being located on the outer side of the guide post 222, and the guide post 222 being movably disposed on the positioning sleeve 24. The positioning head 221 moves along the second direction to the outside of the positioning port 241 until the second positioning surface 2222 is in contact with the positioning port 241. Thus, by utilizing the cooperation between the second positioning surface 2222 and the positioning port 241, the positioning part 22 is prevented from being pushed out by the first elastic part 21.

[0063] Specifically, the second positioning surface 2222 abuts against the positioning port 241, the positioning head 221 extends to the outside of the positioning port 241, and the first elastic part 21 is compressed and deformed. The mounting bracket 1 is provided with a first threaded hole. The first screw 25 is threadedly connected to the first threaded hole to fix the fixing seat 23 to the mounting bracket 1. The mounting bracket 1 is also provided with two clearance holes 1311. Two positioning sleeves 24 are respectively provided in the corresponding clearance holes 1311. One end of the positioning sleeve 24 abuts against the fixing seat 23, and the other end forms the positioning port 241. The positioning port 241 retracts inward. The second positioning surface 2222 can be configured as a toroidal surface, which is opposite to the fixing seat 23, so as to abut against the positioning port 241.

[0064] Optionally, such as Figure 13 As shown, the positioning head 221 is provided with a weight-reducing groove. A reinforcing rib protrudes from the inner side of the weight-reducing groove, and the reinforcing rib abuts against the end of the compression spring. The outer side of the positioning head 221 is a hemispherical surface. The side of the hemispherical surface near the limiting bottom surface 113 forms the aforementioned first positioning surface 2211, and the side away from the limiting bottom surface 113 forms the first guide surface 2212 (as shown). Figure 12 (As shown). When the nose bridge A1 is pressed into the nose bridge groove 11, the bottom of the nose bridge A1 abuts against the first guide surface 2212, which can push the positioning part 22 away from the nose bridge A1.

[0065] In some implementations, such as Figure 3 As shown, the housing 32 includes a first housing 322, which has a connecting window 321. The head-mounted device fixing device 7 includes an adjustment assembly 4. Further referencing... Figure 7 and Figure 14 As shown, the adjustment assembly 4 includes a first connecting shaft 41 and a second connecting shaft 42, with the second connecting shaft 42 positioned closer to the nose bridge groove 11 relative to the first connecting shaft 41. The first connecting shaft 41 is connected to the first housing 322 and the mounting bracket 1 to form a first kinematic pair 431, and the second connecting shaft 42 is connected to the first housing 322 and the mounting bracket 1 to form a second kinematic pair 432. The adjustment assembly 4 is configured such that, in the depth direction of the connecting window 321, the travel distance of the mounting bracket 1 on the side closer to the nose bridge groove 11 is greater than the travel distance on the side farther from the nose bridge groove 11.

[0066] like Figure 14 As shown, in this embodiment, the mounting bracket 1 is movably disposed within the connecting window 321. The first kinematic pair 431 and the second kinematic pair 432 in this embodiment provide different ranges of motion on the upper and lower sides of the mounting bracket 1. A pressing surface 135 is formed on the side of the mounting bracket 1 away from the housing 32. In state I, the pressing surface 135 is in an inclined state. When the protective part 6 is folded, pushing the pressing surface 135 can drive the mounting bracket 1 to move inward toward the housing 32, causing the inclined pressing surface 135 to approach the connecting window 321 and be approximately parallel to the connecting window 321.

[0067] Optionally, the mounting bracket 1 is provided with a first connecting hole 51, and the first housing 322 is provided with a second connecting hole 52. The first connecting shaft 41 passes through the first connecting hole 51 and the second connecting hole 52. The first connecting hole 51 and the second connecting hole 52 can both be configured as round holes, so that the first kinematic pair 431 forms a rotating pair. In contrast, the second kinematic pair 432 is provided with an arc-shaped slide, and the mounting bracket 1 slides along the arc-shaped slide via the second connecting shaft 42 to cooperate with the movement of the first kinematic pair 431. As a result, the movement stroke of the mounting bracket 1 on the side closer to the nose bridge groove 11 is greater than the movement stroke on the side farther from the nose bridge groove 11. When the protective part 6 is folded (the smart glasses A is removed), the pressing surface 135 is parallel to the inner wall of the protective part 6.

[0068] In some implementations, such as Figure 3 , Figure 6 , Figure 7 and Figure 14 As shown, one of the first connecting hole 51 and the second connecting hole 52 is a round hole, and the other is an oblong hole. The first kinematic pair 431 is configured such that when the mounting bracket 1 moves a predetermined distance along the depth direction of the connecting window 321, the first connecting shaft 41 is rotatably connected to the round hole, and the first connecting shaft 41 moves along the length direction of the oblong hole. Alternatively, the first kinematic pair 431 is configured such that the first connecting shaft 41 is fixedly connected to the round hole, and the first connecting shaft 41 moves along the length direction of the oblong hole and rotates within the oblong hole.

[0069] Optionally, the first connecting hole 51 can be configured as a round hole, and the second connecting hole 52 as an oblong hole. Alternatively, the first connecting hole 51 can be configured as an oblong hole, and the second connecting hole 52 as a round hole. This allows the first kinematic pair 431 to have a rotational degree of freedom relative to the central axis of the first connecting shaft 41, and a linear degree of freedom for the first connecting shaft 41 to slide along the length of the oblong hole. On the other hand, as... Figure 14 As indicated by the arrow in state I, during the insertion of the nose bridge A1 into the nose bridge groove 11, the nose bridge A1 applies downward pressure through the positioning part 22 or the nose bridge groove 11. This pressure acts on the first kinematic pair 431 and the second kinematic pair 432. In this configuration, the first connecting shaft 41 and the circular hole are closer to the second housing 323 relative to the positioning head 221 and the nose bridge groove 11. This allows the second kinematic pair 432 to withstand the downward pressure, preventing the mounting bracket 1 from moving inward toward the housing 32 during the downward pressing process.

[0070] Optionally, the first connecting shaft 41 may be configured with a gap between itself and the circular hole, allowing the first connecting shaft 41 to rotate within the circular hole, and a gap between itself and the elongated hole, allowing the first connecting shaft 41 to slide along the elongated hole. Alternatively, the first connecting shaft 41 may be interference-fitted with the circular hole, in which case the first connecting shaft 41 rotates within the elongated hole and can also slide along the length of the elongated hole.

[0071] In some implementations, such as Figure 3 , Figure 7 and Figure 14 As shown, the mounting bracket 1 has a third connecting hole 53, and the first housing 322 has a fourth connecting hole 54. The second connecting shaft 42 passes through the third connecting hole 53 and the fourth connecting hole 54. Both the third connecting hole 53 and the fourth connecting hole 54 are oblong holes, and the total length of the oblong holes in the second kinematic pair 432 is greater than the length of the oblong holes in the first kinematic pair 431. The second kinematic pair 432 is configured such that when the mounting bracket 1 moves a predetermined distance along the depth direction of the connecting window 321, the second connecting shaft 42 moves along the length direction of the third connecting hole 53 and the fourth connecting hole 54.

[0072] Specifically, such as Figure 14 As shown in states I to II, when the pressing surface 135 is pressed, it will first rotate along the first connecting shaft 41. In this form, the side of the mounting bracket 1 closest to the nose bridge groove 11 moves inward toward the connecting window 321. Figure 14 As shown in states II to III, continued pressing of the pressing surface 135 will cause the mounting bracket 1 to translate along the depth direction of the connecting window 321. During the above process, the two elongated holes of the second kinematic pair 432 can guide the movement of the second connecting shaft 42, so that the movement range of the second kinematic pair 432 is greater than that of the first kinematic pair 431, so that the mounting bracket 1 can have different movement modes in the two stages.

[0073] Specifically, such as Figure 14 As shown in state I, the second elastic part 44 pushes the mounting bracket 1 to its outermost position. In this configuration, the second connecting shaft 42 abuts against the end of the fourth connecting hole 54 away from the second housing 323 and the end of the third connecting hole 53 near the second housing 323. The first connecting shaft 41 abuts against the side of the first connecting hole 51 (circular hole) near the second housing 323 and the end of the second connecting hole 52 away from the second housing 323. Thus, the movement range of the mounting bracket 1 is limited by the first connecting shaft 41 and the second connecting shaft 42, ensuring that at least a portion of the guide wall plate 14 is located within the connecting window 321.

[0074] Specifically, Figure 14As shown in state II, after the pressing surface 135 is pressed (rotated counterclockwise), the pressing surface 135 and the connecting window 321 are in a parallel or approximately parallel state. In this configuration, the end of the second connecting shaft 42 and the fourth connecting hole 54 away from the second housing 323, and the end of the third connecting hole 53 away from the second housing 323, abut against each other. The side of the first connecting shaft 41 (round hole) away from the second housing 323 and the end of the second connecting hole 52 away from the second housing 323 abut against each other. Thus, the position adjustment of the mounting bracket 1 is completed before linear movement.

[0075] Specifically, Figure 14 As shown in state III, the mounting bracket 1 moves to the innermost side of the housing 32, with most of the mounting bracket 1 entering the interior of the housing 32. In this configuration, the second connecting shaft 42 abuts against the end of the fourth connecting hole 54 near the second housing 323 and the end of the third connecting hole 53 away from the second housing 323. The first connecting shaft 41 abuts against the side of the first connecting hole 51 (circular hole) away from the second housing 323 and the end of the second connecting hole 52 near the second housing 323. This allows for the folding operation of the head-mounted device fixing device 7, reducing the space occupied by the protective part 6.

[0076] In some implementations, such as Figure 14 As shown, both the second connecting hole 52 and the fourth connecting hole 54 extend along the depth direction of the connecting window 321, and the two ends of the second connecting hole 52 are aligned with the two ends of the fourth connecting hole 54 in the depth direction of the connecting window 321. Thus, in this embodiment, the mounting bracket 1 can be translated in the second stage, thereby entering the inner side of the housing 32 along the depth direction of the connecting window 321.

[0077] In some implementations, such as Figure 14 As shown, in the width direction of the elongated hole, the gap between the third connecting hole 53 and the second connecting shaft 42 is greater than the gap between the fourth connecting hole 54 and the second connecting shaft 42. The gap between the fourth connecting hole 54 and the second connecting shaft 42 is the same as the gap between the second connecting hole 52 and the first connecting shaft 41.

[0078] It is easy to understand that in the first stage, when the mounting bracket 1 rotates along the first connecting shaft 41, the third connecting hole 53 will rotate along an arc. Therefore, the gap between the third connecting hole 53 and the second connecting shaft 42 is configured to be larger, so that when the mounting bracket 1 is under pressure, the second connecting shaft 42 will not interfere with the third connecting hole 53. That is, the second connecting shaft 42 can move simultaneously along both the width and length directions of the third connecting hole 53. At the same time, it also allows the mounting bracket 1 to rotate preferentially to adjust the positional relationship between the mounting bracket 1 and the connecting window 321, so as to facilitate linear movement in the second stage and prevent the mounting bracket 1 from jamming against the window edge of the connecting window 321.

[0079] Optionally, the diameters of the first connecting shaft 41 and the second connecting shaft 42 are consistent along their length. All of the aforementioned elongated holes extend in a straight line, and the width and length of the third connecting hole 53 are both greater than those of the fourth connecting hole 54.

[0080] Optionally, the first connecting shaft 41 and the second connecting shaft 42 may also be provided with multiple steps, so as to achieve axial positioning of the first connecting shaft 41 and the second connecting shaft 42 by the cooperation of the steps with the first connecting hole 51, the second connecting hole 52, the third connecting hole 53 and the fourth connecting hole 54.

[0081] In some implementations, such as Figure 3 and Figure 7 As shown, the shell portion 32 also includes a second shell portion 323, which is assembled with the first shell portion 322 to form a receiving cavity 324, and the energy storage portion 33 is disposed in the receiving cavity 324. The adjustment assembly 4 also includes a second elastic portion 44, which abuts against the second shell portion 323 and the mounting bracket 1, and pushes the mounting bracket 1 away from the second shell portion 323.

[0082] Optionally, the second elastic part 44 can be an elastic component such as a torsion spring, compression spring or disc spring to drive the first limiting side 111 away from the shell part 32, so as to ensure that the opening of the nose bridge groove 11 can be in the open state.

[0083] It should be noted that the first fixing part 2a and the second fixing part 2b are provided on the mounting bracket 1. Therefore, when the mounting bracket 1 moves towards the second housing 323, it can move the positioning part 22 along with it. This avoids interference from the positioning assembly 2 on the folding of the protective part 6.

[0084] In some implementations, such as Figure 9 As shown, the second elastic part 44 includes a first elastic member 441 and a second elastic member 442. The first elastic member 441 is disposed on the side of the mounting frame 1 near the nose bridge groove 11, and the second elastic member 442 is disposed on the side of the mounting frame 1 away from the nose bridge groove 11.

[0085] It is easy to understand that in the first stage, the second elastic element 442 is mainly compressed, while in the second stage, the first elastic element 441 and the second elastic element 442 are compressed together. This results in the second elastic element 44 having a greater elastic force in the second stage than in the first stage, ensuring that the mounting bracket 1 can rotate first and then move linearly. Thus, before the mounting bracket 1 moves linearly, the positional relationship between the mounting bracket 1 and the connecting window 321 is adjusted.

[0086] In some implementations, such as Figures 7-9As shown, both the first elastic element 441 and the second elastic element 442 are torsion springs. Each torsion spring includes a coil 443 and multiple drive arms 444 connected to the coil 443. The coil 443 of the first elastic element 441 is sleeved on the first connecting shaft 41, and the coil 443 of the second elastic element 442 is sleeved on the second connecting shaft 42. The multiple drive arms 444 of each torsion spring respectively abut against the mounting bracket 1 and the second housing 323.

[0087] Optionally, such as Figure 9 As shown, each torsion spring includes two coils 443, four drive arms 444, and a connecting arm. Each coil 443 corresponds to two drive arms 444. The two drive arms 444 on opposite sides of the two coils 443 are connected together by the connecting arm. This causes two drive arms 444 of each torsion spring to abut against the second housing 323, and the other two drive arms 444 to abut against the mounting bracket 1. Thus, during the movement of the first connecting shaft 41 and the second connecting shaft 42, the positioning of the first elastic element 441 and the second elastic element 442 is achieved.

[0088] In some implementations, such as Figure 6 and Figure 8 As shown, the mounting bracket 1 includes a floating part 13 and a guide wall plate 14. The floating part 13 is provided with a nose bridge groove 11. The guide wall plate 14 protrudes from the floating part 13 and extends into the second housing 323. The guide wall plate 14 is slidably disposed within the connecting window 321 and is provided with a first connecting hole 51 and a third connecting hole 53. In this embodiment, the guide wall plate 14 cooperates with the inner side of the window edge of the connecting window 321 to limit the floating part 13.

[0089] In some implementations, such as Figure 8 As shown, the guide wall panel 14 includes two first plates 141 in the extending direction. The two first plates 141 are parallel and spaced apart, and each first plate 141 is provided with a first connecting hole 51 and a third connecting hole 53. Further referencing... Figure 3 and Figure 14 As shown, the first housing 322 includes two first lugs 3221 and two second lugs 3222. The two first lugs 3221 and the two second lugs 3222 protrude from the edge of the connecting window 321 and extend toward the second housing 323. The two first lugs 3221 and the two second lugs 3222 are located on both sides of the two first plates 141, and each first lug 3221 is provided with a second connecting hole 52, and each second lug 3222 is provided with a fourth connecting hole 54.

[0090] Optionally, in this embodiment, there can be two of each of the first connecting shaft 41 and the second connecting shaft 42, corresponding to the two sets of first connecting holes 51 and the two sets of third connecting holes 53. Alternatively, there can be only one of each of the first connecting shaft 41 and the second connecting shaft 42, such that the first connecting shaft 41 passes through both the two first connecting holes 51 and the two second connecting holes 52, and the second connecting shaft 42 passes through both the two third connecting holes 53 and the two fourth connecting holes 54. This results in a more balanced force distribution on the mounting bracket 1, ensuring the movement accuracy of the mounting bracket 1.

[0091] In some implementations, such as Figure 7 and Figure 9 As shown, the mounting bracket 1 also includes two ribs 15. The two ribs 15 protrude from the floating part 13 and extend towards the second housing 323. The two ribs 15 are parallel to the first plate 141 and located between the two first plates 141. A first limiting groove 151 is formed between the first plate 141 and the adjacent rib 15. There are two first elastic members 441 and two second elastic members 442. The two first elastic members 441 and the two first limiting grooves 151 are correspondingly arranged. At least one drive arm 444 of each torsion spring abuts against the floating part 13 and extends into the corresponding first limiting groove 151. In this embodiment, the ribs 15 can increase the structural strength of the mounting bracket 1, while the first limiting grooves 151 can restrict the axial position of the torsion springs on the first connecting shaft 41 and the second connecting shaft 42, preventing the torsion springs from moving freely.

[0092] In some implementations, such as Figure 9 As shown, a second limiting groove 152 is formed between the two ribs 15. The first elastic part 21 is an elastic sheet 211, which includes a fixed section 2111, an intermediate section 2113, and a driving section 2112 in sequence along its extension direction. The positioning part 22 is disposed on the driving section 2112, and the fixed section 2111 is fixedly connected to the mounting bracket 1. When the positioning head 221 moves above the nose bridge groove 11, at least part of the intermediate section 2113 is located in the second limiting groove 152. In this embodiment, the second limiting groove 152 is used to limit the position of the elastic sheet 211 to ensure the movement accuracy of the positioning head 221.

[0093] In some implementations, such as Figures 7-9As shown, the intermediate section 2113 includes a curved section 2114 and a connecting section 2115 in the extending direction. One end of the curved section 2114 is connected to the driving section 2112, and the other end is connected to the fixing section 2111 via the connecting section 2115. At least a portion of the connecting section 2115 is correspondingly disposed with the second limiting groove 152. The second connecting shaft 42 is located between the two ribs 15 and the curved section 2114, and the curved section 2114 bends away from the second connecting shaft 42. In this embodiment, the curved section 2114 can avoid the second connecting shaft 42, making the internal structure of the head-mounted device fixing device 7 more compact. At the same time, the curved section 2114 can also undergo a certain degree of extension deformation, increasing the deformation range of the elastic sheet 211.

[0094] In some implementations, such as Figures 8-9 As shown, the guide wall plate 14 also includes a second plate 142 and a third plate 143 in the extending direction. The ends of the two first plates 141 on the same side are connected by the second plate 142 or the third plate 143. The second plate 142 is closer to the positioning head 221 than the third plate 143, and the third plate 143 has a notch 1431 in the length direction. The connecting section 2115 passes between the first connecting shaft 41 and the floating part 13 and is connected to the fixed section 2111. The fixed section 2111 passes through the notch 1431 and bends away from the driving section 2112, and the end of the fixed section 2111 is fixedly connected to the side of the floating part 13 away from the shell part 32. Thus, when the positioning head 221 is away from the nose bridge groove 11, the fixed section 2111 can also provide a certain deformation range, reducing the friction between the nose bridge A1 and the positioning part 22. When the movement of the positioning head 221 is too large, the connecting section 2115 can abut against the first connecting shaft 41 to limit the movement of the positioning head 221.

[0095] Optionally, such as Figure 8 As shown, the end of the fixed section 2111 is provided with a connecting through hole. The second fixing part 2b also includes a second screw 26. The mounting bracket 1 is provided with a second threaded hole. The second screw 26 passes through the connecting through hole and is threaded into the second threaded hole to abut the end of the fixed section 2111 against the side of the floating part 13 away from the shell part 32, thereby increasing the deformation range of the elastic sheet 211.

[0096] Optionally, the height of the third plate 143 is less than that of the second plate 142. Therefore, in the first stage, when the mounting bracket 1 is in a position away from the second housing 323 ( Figure 14 As shown in state I), this ensures that the third plate 143 is always within the connecting window 321, thereby improving the positional accuracy between the connecting window 321 and the mounting bracket 1.

[0097] In some implementations, such as Figure 8 and Figure 9As shown, the floating part 13 includes a main wall panel 131 and a seat part 132. A guide wall panel 14 extends along the edge of the main wall panel 131 and folds towards the side of the main wall panel 131 away from the nose bridge groove 11. The seat part 132 protrudes from the side of the main wall panel 131 away from the guide wall panel 14. The seat part 132 includes a base 1321 and a baffle 1322. The side of the base 1321 near the positioning head 221 forms a limiting bottom surface 113 and protrudes with the baffle 1322. The side of the baffle 1322 facing the main wall panel 131 is the first limiting side surface 111. In the arrangement direction of the two positioning heads 221, the length of the baffle 1322 is less than the limiting bottom surface 113. In this embodiment, the length of the baffle 1322 is limited to avoid obstructing the nose bridge. When the nose pads are connected to the frame via the nose pad brackets, the two nose pad brackets can extend from both sides of the barrier 1322 to above the pressing surface 135 so that the nose pads avoid the floating part 13.

[0098] Optionally, the side of the retaining wall 1322 away from the shell 32 and the side of the base 1321 away from the shell 32 together form the pressing surface 135.

[0099] In some implementations, such as Figures 8-11 As shown, the base 1321 has two mounting holes 133. Further referencing... Figure 9 As shown, the floating part 13 is provided with a receiving groove 134, which is recessed from the main wall plate 131 toward the base 1321. The power supply part is provided in the receiving groove 134, and the number of power supply contacts 311 is two, which extend from the two mounting holes 133 into the nose bridge groove 11 respectively.

[0100] Optionally, in this embodiment, the receiving groove 134 is connected to the second limiting groove 152 to facilitate the insertion of the power supply part 31 into the receiving groove 134. The power supply contact 311 is a telescopic head that can move downward when the nose bridge A1 is pressed down. In addition, setting the power supply contact 311 on the limiting bottom surface 113 can ensure the stability of the electrical connection.

[0101] In some implementations, such as Figure 8 and Figure 11 As shown, the main wall panel 131 is provided with two clearance holes 1311, and two positioning heads 221 extend from the two clearance holes 1311 respectively. Therefore, in this embodiment, the positioning heads 221 are accommodated by the clearance holes 1311, thereby improving the movement accuracy of the positioning heads 221.

[0102] In an alternative implementation, the head-mounted device fixing device 7 in the above embodiments can be applied to a head-mounted device storage case. The head-mounted device storage case also includes a protective part 6. The protective part 6 is provided with a storage cavity 64 (e.g., Figure 19 (As shown). The head-mounted device fixing device 7 is disposed in the storage cavity 64 and fixedly connected to the protective part 6.

[0103] In summary, in this embodiment, the head-mounted device storage box has the positioning part 22 positioned on the first elastic part 21, so that the positioning head 221 can move closer to or away from the nose bridge groove 11 via the first elastic part 21. Therefore, when installing the smart glasses A, the positioning head 221 can avoid the nose bridge A1, facilitating the insertion of the nose bridge A1 into the nose bridge groove 11. Once the nose bridge A1 is in place, driven by the first elastic part 21, the positioning head 221 abuts against the nose bridge A1 to fix it, thus simplifying the operation of the head-mounted device fixing device and facilitating the fixing and removal of the smart glasses A. Furthermore, by configuring the positioning head 221 to extend towards the side of the nose bridge groove 11 where the first limiting side 111 is located, the positioning head 221 can avoid the nose pad and temple A3 during fixing, improving the adaptability of the head-mounted device fixing device 7 to different types of smart glasses A.

[0104] Figure 15 This is an exploded view of the other side of the head-mounted device storage box in this embodiment.

[0105] In some implementations, such as Figure 1 and Figure 15 As shown, the head-mounted device storage case includes a protective part 6 and a head-mounted device fixing device 7. The head-mounted device fixing device 7 has a nose bridge limiting space 12, which is used to fix the head-mounted device.

[0106] Figure 16 This is a schematic diagram of the structure of the first folded part 61 in this embodiment. Figure 17 and Figure 18 This is an exploded view of the second fold 62 in this embodiment.

[0107] Further reference Figures 15-18 As shown, the protective part 6 includes a first folding part 61 and a second folding part 62. The first folding part 61 includes a plurality of side wall panels 611 in the extending direction, and the plurality of side wall panels 611 include a first side panel body 6111 and a second side panel body 6112. The second folding part 62 includes a deformation connecting structure 63 and at least one end wall panel 621. The head-mounted device fixing device 7 is disposed on the second side panel body 6112 and is disposed adjacent to the first side panel body 6111. The first side panel body 6111 is folded toward the second side panel body 6112 at a predetermined angle. The end wall panel 621 is movably connected to the first side panel body 6111 through the deformation connecting structure 63, and the end wall panel 621 is movably connected to the head-mounted device fixing device 7 through the deformation connecting structure 63.

[0108] Figure 19 This is a structural schematic diagram of the first folded state 6a of this embodiment. The figure shows the general outline of the smart glasses A with dotted lines. Figure 20 This is a schematic diagram of the second folded state 6b in this embodiment. Figure 19 and Figure 20The second fold 62 is not shown in the image.

[0109] Further reference Figure 19 As shown, the protective part 6 has a first folded state 6a. In the first folded state 6a, the first folded part 61 forms a first receiving channel 6c, and the end wall plate 621 covers the end of the first receiving channel 6c. The edge of the end wall plate 621 abuts against the first side plate 6111 and the second side plate 6112. Thus, the first receiving channel 6c can be used to receive the smart glasses A and the head-mounted device fixing device 7. After the head-mounted device fixing device 7 fixes the smart glasses A, it can prevent the smart glasses A from moving around in the first receiving channel 6c. In this configuration, the temples A3 of the smart glasses A are close to the first side plate 6111, and the lenses are close to the second side plate 6112. When the size of the smart glasses A is large, causing the temples A3 to contact the inner wall of the first folded part 61, the floating part 13 can be used to adjust the posture of the smart glasses A within a certain range, changing the positional relationship between the smart glasses A and the shell part 32, thereby further increasing the adaptability of the protective part 6.

[0110] Further reference Figure 20 As shown, the protective part 6 also has a second folded state 6b. In the second folded state 6b, the first folded part 61 closes to form a second receiving channel 6d, and the first side plate 6111 and the second side plate 6112 are arranged opposite each other. The head-mounted device fixing device 7 is located between the first side plate 6111 and the second side plate 6112, and the end wall plate 621 folds over to the head-mounted device fixing device 7 and drives the deformation connecting structure 63 to deform. In this configuration, the smart glasses A are removed from the protective part 6, and the protective part 6 is used to protect the head-mounted device fixing device 7. At the same time, the volume occupied by the protective part 6 is reduced. During this process, the deformation connecting structure 63 is used to guide the movement direction of the end wall plate 621.

[0111] In summary, the head-mounted device storage box in this embodiment has the head-mounted device fixing device 7 disposed on the second side plate 6112 and adjacent to the first side plate 6111. Therefore, in the first folded state 6a, the protective part 6 can simultaneously protect both the head-mounted device and the head-mounted device fixing device 7. In the second folded state 6b, it can protect the head-mounted device fixing device 7 while reducing the volume occupied by the protective part 6. This improves the convenience of the head-mounted device storage box. On the other hand, the end wall plate 621 is movably connected to the first side plate 6111 and the head-mounted device fixing device 7 respectively through the deformable connection structure 63. This keeps the end wall plate 621 connected to both the first side plate 6111 and the head-mounted device fixing device 7, reducing the number of steps required to fold the protective part 6 and lowering the user's learning curve. Furthermore, the head-mounted device fixing device 7 indirectly restricts the range of motion of the end wall plate 621, helping the user to fold the protective part 6 so that the end wall plate 621 fits more snugly against the head-mounted device fixing device 7.

[0112] In some implementations, such as Figure 15 As shown, the deformable connection structure 63 includes a first connecting portion 631 and a second connecting portion 632. Further referring to... Figure 17 and Figure 18 As shown, the end wall panel 621 includes a first edge 6211 and a second edge 6212. The first edge 6211 is movably connected to the inner side of the first side panel 6111 via a second connecting part 632, and the end wall panel 621 is movably connected to the head-mounted device fixing device 7 via the first connecting part 631. In the first folded state 6a, the first edge 6211 abuts against the first side panel 6111, and the second edge 6212 abuts against the second side panel 6112. In this embodiment, the first edge 6211 and the second edge 6212 are at a predetermined angle, so that the first edge 6211 and the second edge 6212 provide lateral support for the first folded part 61, effectively reducing the inward collapse of the first folded part 61 when the protective part 6 is squeezed.

[0113] In some implementations, such as Figure 15 As shown, the head-mounted device fixing device 7 also includes a housing portion 32, which has a clamping gap 325 located on the side of the head-mounted device fixing device 7 away from the second side plate 6112. The first connecting portion 631 is a flexible band 6334, one end of which is clamped in the clamping gap 325, and the other end extends to the end wall plate 621. In this embodiment, the deformation characteristics of the flexible band 6334 are utilized so that the flexible band 6334 can be fixed by the clamping gap 325, while also driving the end wall plate 621 to swing.

[0114] Optionally, in the second folded state 6b, the head-mounted device fixing device 7 is compressed, causing the nose bridge limiting space 12 to move toward the shell portion 32. This reduces the thickness of the head-mounted device fixing device 7, making it easier to position the head-mounted device fixing device 7 within the second receiving channel 6d.

[0115] Optionally, such as Figure 15 As shown, the shell portion 32 includes a first shell 322, a second shell 323, and a fixing block 328. The second shell 323 has a third threaded hole. The first shell 322 and the second shell 323 form an accommodating cavity 324. The fixing block 328 has a clamping gap 325, through which the flexible strip 6334 can be inserted and bonded to the fixing block 328. Then, the two fixing blocks 328 are placed on the two side windows 326 on both sides of the first shell 322 and threadedly connected to the third threaded hole by a third screw, so that the fixing blocks 328 are fixedly connected to the second shell 323 to complete the fixing operation of the flexible strip 6334.

[0116] In some implementations, such as Figure 15 , Figure 17 and Figure 18 As shown, the second connecting part 632 includes a connecting plate 622. The connecting plate 622 is provided with a first plate surface 6221 (e.g., ...). Figure 17 The area shown by the mid-section line) and the second plate surface 6222. The first plate surface 6221 is opposite to the second plate surface 6222.

[0117] Figure 21 and Figure 22 This is an exploded view of the first folded portion 61 and the second folded portion 62 in this embodiment. Figure 23 This is a schematic diagram of the folding process of the head-mounted device storage box in this embodiment.

[0118] Further reference Figure 18 and Figure 23 As shown, one edge of the connecting plate 622 forms a first crease 623 with the first edge 6211, and the other edge is rotatably connected to the first side plate 6111. In the first folded state 6a, the first plate surface 6221 abuts against the first side plate 6111. Figure 23 The corresponding area of ​​the first side plate 6111 is shown in the cross-section.

[0119] Further reference Figure 18 , Figure 20 and Figure 23 As shown, in the second folded state 6b, the end wall plate 621 is configured to fold towards the head-mounted device fixing device 7 and drive the connecting plate 622 to swing towards the head-mounted device fixing device 7 until the connecting plate 622 is sandwiched between the end wall plate 621 and the first side plate 6111, and the first plate surface 6221 abuts against the side of the end wall plate 621 away from the second side plate 6112.

[0120] In this embodiment, the connecting plate 622 has a certain degree of rigidity. When the user presses the end wall plate 621 inward, the connecting plate 622 can swing along the second crease 624, causing the first side plate 6111 to fold towards the second side plate 6112. This simplifies the folding method of the protective part 6. On the other hand, in the first folded state 6a, the connecting plate 622 abuts against the first side plate 6111, so that the connecting plate 622 and the end wall plate 621 can together provide support for the first side plate 6111, increasing the rigidity of the protective part 6.

[0121] In some implementations, such as Figure 15 and Figures 21-22 As shown, the second connecting portion 632 also includes a fixing plate 625. The fixing plate 625 is fixedly connected to the inner side of the first side plate 6111, and the edge of the fixing plate 625 forms a second crease 624 with the edge of the connecting plate 622. In the second folded state 6b, the connecting plate 622 swings toward the head-mounted device fixing device 7 through the second crease 624. In this embodiment, the fixing plate 625 can increase the connection strength between the first folded portion 61 and the second folded portion 62, so that the end wall plate 621 can drive the first side plate 6111 to swing through the deformation connection structure 63.

[0122] In some implementations, such as Figures 21-22 As shown, one of the fixing plate 625 and the first side plate 6111 is provided with a positioning boss 6115, and the other is provided with a positioning groove 6251. When the side of the fixing plate 625 away from the head-mounted device fixing device 7 abuts against the first side plate 6111, the positioning boss 6115 engages with the positioning groove 6251.

[0123] Optionally, the first side plate 6111 is provided with a positioning boss 6115, and the fixing plate 625 is provided with a positioning groove 6251. Adhesive can be applied to the inside of the positioning groove 6251 to make the positioning groove 6251 and the positioning boss 6115 stably connected. At the same time, the positioning groove 6251 and the positioning boss 6115 can improve the assembly accuracy of the protective part 6.

[0124] In some implementations, such as Figures 15-22 As shown, there are two end wall plates 621, two first connecting portions 631, and two connecting plates 622, and they are arranged correspondingly. A fixing plate 625 is connected between the two connecting plates 622. In the first folded state 6a, the second crease 624 is inclined towards the end of the second side plate 6112, and the two second creases 624 are inclined in a direction away from each other, that is, the second creases 624 are away from each other in the direction towards the second side plate 6112. Furthermore, the second crease 624 and the first crease 623 are mirror-symmetrical with respect to the reference surface 6e. Wherein, the reference surface 6e (e.g., Figure 1(As shown) is perpendicular to the extension direction of the first accommodating channel 6c and located at the center of the first accommodating channel 6c. As a result, the movement range of both ends of the first side plate 6111 is consistent, and in the second folded state 6b, the protective part 6 is flatter.

[0125] In some implementations, such as Figures 17-18 As shown, the deformable connection structure 63 includes a connecting wall panel 634 and a first flexible fabric layer 633. The connecting wall panel 634 includes a fixing plate 625 and a connecting plate 622. The first flexible fabric layer 633 includes an adhesive area and a flexible strip 6334, with the adhesive area attached to the connecting wall panel 634 and the end wall panel 621. In the first folded state 6a, the first flexible fabric layer 633 is located inside the connecting wall panel 634.

[0126] Optionally, in this embodiment, the first flexible fabric layer 633 can be bonded to the connecting wall panel 634. The first flexible fabric layer 633 can be made of materials such as microfiber cloth or nylon fabric, giving it a certain degree of flexibility and resilience, ensuring that the deformation connection structure 63 can be repeatedly bent. Simultaneously, the first flexible fabric layer 633 also protects the smart glasses A.

[0127] In some implementations, such as Figures 17-18 As shown, the bonding area includes a first bonding area 6331, a second bonding area 6332, and a third bonding area 6333. The first bonding area 6331 is attached to the fixing plate 625, the second bonding area 6332 is attached to the connecting plate 622, and the third bonding area 6333 is attached to the end wall plate 621.

[0128] Further reference Figure 18 , Figure 21 and Figure 23 As shown, the side of the third fitting area 6333 is connected to the flexible strip 6334 to form a third crease 6335. The third crease 6335 is perpendicular to the extension direction of the second receiving channel 6d, and the end wall plate 621 is folded towards the head-mounted device fixing device 7 along the third crease 6335.

[0129] Specifically, the clamping gap 325 is parallel to and adjacent to the corresponding third crease 6335. In this embodiment, the flexibility of the first flexible fabric layer 633 is utilized, allowing the end wall plate 621 to rotate around the third crease 6335.

[0130] In some implementations, such as Figure 18 and Figure 21 As shown, the third crease 6335 is parallel to and spaced apart from the second plate edge 6212. The end wall plate 621 has an abutment area 6216 on its surface (e.g., Figure 18(Area shown in the mid-section line). The abutment area 6216 is located between the third crease 6335 and the second plate edge 6212. In the first folded state 6a, the abutment area 6216 abuts against the outer side of the shell portion 32.

[0131] Specifically, such as Figure 15 As shown, the second housing 323 has two positioning end faces 327. The two positioning end faces 327 are located inside the second receiving channel 6d and face the two ends of the second receiving channel 6d respectively. The abutment area 6216 is used to abut against the positioning end faces 327 so that the end wall plate 621 remains upright in the first folded state 6a.

[0132] In some implementations, such as Figure 16 As shown, the first folding portion 61 also includes a plurality of flexible plates 612 in its extending direction. In the extending direction of the first folding portion 61, two adjacent sidewall plates 611 are connected by two flexible plates 612. In the first folded state 6a and the second folded state 6b, each sidewall plate 611 extends along a plane, and the flexible plates 612 bend and deform in a direction away from the head-mounted device fixing device 7. In this embodiment, the flexible plates 612 utilize their own flexibility to provide deformation for the first folding portion 61.

[0133] In some implementations, such as Figures 1-20 As shown, the end wall panel 621 includes at least three straight edges 6214 and multiple rounded edges 6215, with adjacent straight edges 6214 connected by rounded edges 6215. In the first folded state 6a, the straight edges 6214 abut against the side wall panel 611, and the rounded edges 6215 abut against the flexible plate 612. Therefore, the end wall panel 621 can better support the first receiving channel 6c and reduce the gap between the end wall panel 621 and the inner wall of the first receiving channel 6c.

[0134] Optionally, the number of straight edge plates 6214 can be four, five or more, and the end wall plate 621 can be a rounded polygonal structure. Correspondingly, the number of side wall plates 611 is also increased, thereby increasing the internal space of the first accommodating channel 6c.

[0135] Specifically, such as Figure 18 As shown, there are three straight edges 6214 and three rounded edges 6215. The three straight edges 6214 are designated as the first edge 6211, the second edge 6212, and the third edge 6213. Figure 16 As shown, there are four side panels 611: a first side panel 6111, a second side panel 6112, a third side panel 6113, and a fourth side panel 6114. In the first folded state 6a, the fourth side panel 6114 abuts against the outer surface of the first side panel 6111. Figure 20As shown, in the second folded state 6b, the fourth side plate 6114 abuts against the outer side of the second side plate 6112, and the first side plate 6111 and the third side plate 6113 abut against each other.

[0136] Figure 24 yes Figure 23 A cross-sectional view at point CC.

[0137] Optionally, such as Figure 24 As shown, the first folding portion 61 can also be configured as a double-layer structure. The first folding portion 61 includes an outer shell plate 6116 and a second flexible fabric layer 6117. The outer shell plate 6116 includes a plurality of the aforementioned side wall plates 611 and a plurality of flexible plates 612. The material of the second flexible fabric layer 6117 can be the same as or different from that of the first flexible fabric layer 633.

[0138] Furthermore, such as Figure 24 As shown, a support plate 6118 is provided on the inner side of each sidewall panel 611. The support plate 6118 can increase the rigidity of the sidewall panel 611. At the same time, the flexible plate 612, the first crease 623 and the second crease 624 can be formed by hot pressing, making the flexible plate 612 easier to bend in a specific direction. The first crease 623 and the second crease 624 can also be configured as a fracture structure and connected by the first flexible fabric layer 633.

[0139] Meanwhile, the connecting plate 622 and the fixing plate 625 are both located on the inner edge of the first side plate 6111, making the protective part 6 more aesthetically pleasing.

[0140] Optionally, the support plate 6118 of the first side plate 6111 and the support plate 6118 of the fourth side plate 6114 form a magnetic attraction pair. At the same time, the support plate 6118 of the second side plate 6112 and the support plate 6118 of the fourth side plate 6114 form another magnetic attraction pair, so that the fourth side plate 6114 can be attracted to the first side plate 6111 and the second side plate 6112 respectively.

[0141] Optionally, such as Figure 18 and Figure 23 As shown, the second edge 6212 of an end wall plate 621 and the corresponding flexible strip 6334 are both provided with clearance openings, which are used to avoid the charging port inside the housing 32.

[0142] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
