Description

Technical Field

[0001] This application relates to the field of smart devices, and more particularly to a type of smart glasses. Background Art

[0002] With the development of technology, smart glasses have become a common electronic device in people's daily lives. Smart glasses typically consist of an interconnected frame and temples, with the temples worn on the user's face. However, different users have different body shapes and wearing needs, including varying requirements for temple length. Temples that are too short will make it impossible for the user to wear them, while temples that are too long will cause the smart glasses to slip off during wear, affecting the user experience. Utility Model Content

[0003] This application provides a smart pair of glasses for adjusting the relative position between the temples and the frame.

[0004] A first aspect of this application provides smart glasses, the smart glasses comprising:

[0005] Picture frames;

[0006] Hinge assembly;

[0007] The temples are rotatably connected to the frame via the hinge assembly.

[0008] The temple is movable relative to the hinge assembly in a direction that is close to or away from the frame, thereby changing the distance between the wearing part of the temple and the frame. The hinge assembly and the temple are provided with a limiting structure, which is used to restrict the relative movement of the temple and the hinge assembly.

[0009] The solution provided in this application, by making the hinge assembly and temples adjustable, allows for changing the relative position between the temples and the hinge assembly, thereby adjusting the relative position between the temples and the frame. This allows for adjusting the distance L between the frame and the temple end without changing the temple length, enabling the smart glasses to adapt to different user needs. Furthermore, the solution provided in this application eliminates the need for a separate temple structure; during adjustment, the temple as a whole moves relative to the frame and hinge assembly, maintaining its integrity. This design reduces the difficulty of arranging circuit boards, wiring, electronic components, and other parts within the temple. During adjustment, the components on the temple remain stationary relative to the temple, resulting in better stability of the electrical connections between components and better meeting practical usage requirements.

[0010] In one possible implementation, the hinge assembly includes a first connecting portion and a second connecting portion connected to each other, the temple includes a third connecting portion connected to the wearing portion, the first connecting portion is rotatably connected to the frame, the second connecting portion and the third connecting portion are sleeved together, and the second connecting portion and the third connecting portion are capable of relative movement along the sleeved direction.

[0011] During connection, the second connecting part can be sleeved on the outside of the third connecting part, or the third connecting part can be sleeved on the outside of the second connecting part. By sleeved the hinge assembly with the temple, the contact area between the hinge assembly and the temple can be increased, thereby improving the stability of the connection between the hinge assembly and the temple. Moreover, the sleeved connection can guide the movement of the temple relative to the hinge assembly, thereby improving the stability of the relative movement between the temple and the hinge assembly during adjustment, which is more in line with actual usage needs.

[0012] In one possible implementation, the limiting structure includes a limiting member and a limiting recess that can cooperate with each other. In the second connecting part and the third connecting part, one is provided with the limiting member, and the other is provided with at least two limiting recesses spaced apart along the length direction of the temple. The limiting member can cooperate with the limiting recesses for limiting.

[0013] The spacing between each limiting recess can be set according to actual needs. By cooperating with different limiting recesses, the relative position of the temple and the hinge assembly can be changed, thereby adjusting the relative position between the temple and the frame. This allows the smart glasses to adapt to different user needs, improving wearing comfort and stability. It can reduce the possibility of the glasses falling off during use due to excessive distance between the temple and the frame, and also reduce the possibility of the glasses being unable to be worn due to insufficient distance between the temple and the frame.

[0014] In one possible implementation, the second connecting part or the third connecting part is provided with a mounting groove, and the limiting member includes an elastic part and a limiting part. One end of the elastic part is connected to the inner wall of the mounting groove, and the other end is connected to the limiting part. The limiting part can extend out of the mounting groove and cooperate with the limiting recess, or the limiting part can retract into the mounting groove and release the limiting cooperation with the limiting recess.

[0015] The limiting part is located on the side of the elastic part facing the opening of the mounting groove, and at least a portion of the limiting part can extend or retract relative to the opening of the mounting groove. When the limiting part extends relative to the mounting groove, it can engage with a corresponding limiting recess to restrict the relative movement of the temple and the hinge assembly. When the limiting part retracts relative to the mounting groove, it can disengage from the limiting recess, allowing the temple to move relative to the hinge assembly, thereby adjusting the distance between the temple and the frame. By providing a mounting groove, a portion of the limiting member can be located within the mounting groove, thus reducing the space occupied by the limiting member. Simultaneously, the mounting groove can guide the movement of the limiting member during movement, thereby improving the stability of the limiting member's movement.

[0016] In one possible implementation, the third connecting portion is sleeved on the outside of the second connecting portion, the limiting member is disposed on the second connecting portion, and the limiting recess is disposed on the third connecting portion.

[0017] Since the third connecting part is sleeved on the outside of the second connecting part, setting the limiting member on the inner surface of the third connecting part is difficult. Therefore, the limiting member can be set on the second connecting part. Because the third connecting part is sleeved on the outside, it will have a cavity. When the limiting member is set on the third connecting part, it needs to be placed on the sidewall of the cavity. The sidewall thickness of the cavity is relatively small, making the depth of the mounting groove shallow and difficult to set. Therefore, the limiting member is usually set on the second connecting part, which is located on the inside. The mounting groove can be made on the outer surface of the second connecting part, which is easier to process. Furthermore, the radial dimension of the second connecting part is usually larger than the wall thickness of the cavity, so the size of the mounting groove can be relatively large to meet installation and usage requirements.

[0018] In one possible implementation, the limiting structure includes a mating recess, a limiting recess, and a connector. The second connecting portion is provided with at least two limiting recesses spaced apart along the length direction of the temple. The third connecting portion is provided with a mating recess. The mating recess can communicate with any of the limiting recesses. The mating recesses and the limiting recesses that communicate with each other are detachably connected by the connector.

[0019] This design is easy to operate, allowing users to adjust the relative position between the temples and the frame during use.

[0020] In one possible implementation, the second connecting portion is provided with a first thread, the third connecting portion is provided with a second thread, and the second connecting portion is threadedly engaged with the first connecting portion.

[0021] By incorporating threaded structures in the second and third connecting parts, their fit is facilitated. Simultaneously, the threaded connection enhances the stability of this fit, connecting the temple and hinge assembly while guiding their relative movement during the temple's motion relative to the hinge assembly, thus improving stability. The threaded connection structure is simple and easy to manufacture, and it also facilitates easy installation and removal of the temples. During use, the temples can be disassembled to connect with hinge assemblies of different frames, allowing for compatibility with various designs. For storage, the temples can be disconnected from the hinge assembly, separating them from the frame, saving storage space and better meeting practical usage needs.

[0022] In one possible implementation, the distance between adjacent limiting recesses is a, the lead of the first thread and the second thread is b, and a = nb, where n is a positive integer.

[0023] Users can adjust the glasses by moving the temples closer to or further away from the frame according to their needs. 'n' is a positive integer, ensuring that the number of rotations of the temple relative to the hinge assembly during adjustment is an integer. This means that after the user rotates the temple n times relative to the hinge assembly, the limiting part can engage with another limiting recess. This design reduces the possibility of the temple's position changing after adjustment. When 'n' is not a positive integer, the position of the components on the temple may shift after the user adjusts the temple's position, potentially causing the smart glasses to malfunction and become unwearable.

[0024] In one possible implementation, the limiting member includes a limiting part, which is a buckle, and the second connecting part is sleeved on the outside of the third connecting part, and the limiting member is disposed on the third connecting part;

[0025] Along the circumference of the third connecting portion, the third connecting portion is provided with at least two limiting portions, and the at least two limiting portions can move closer to or further away from each other.

[0026] This design allows the limiting components to be molded directly during production, which can save on the installation process, thereby reducing the difficulty of processing, improving processing efficiency, and better meeting actual usage needs.

[0027] In one possible implementation, the limiting member further includes at least two elastic arms, the fixed ends of the elastic arms being fixedly connected to the third connecting portion, and the limiting portion being disposed at the free ends of the elastic arms.

[0028] When the size of the limiting part extending into the limiting recess is too large, the limiting part is not easy to disengage from the limiting recess, making adjustment more difficult. When the size of the limiting part extending into the limiting recess is too small, the fit between the limiting part and the limiting recess is less stable, and the limiting part is prone to disengaging from the limiting recess during use.

[0029] In one possible implementation, the distance between adjacent limiting recesses is a, and 1 mm ≤ a ≤ 5 mm.

[0030] When the distance between adjacent limiting recesses is less than 1 mm, the distance is too small, increasing the difficulty of manufacturing. Furthermore, during adjustment, the adjustment effect is not obvious due to the small distance between adjacent limiting recesses, resulting in low utilization of the limiting recesses. When the distance between adjacent limiting recesses is greater than 5 mm, the distance is too large, causing excessive positional differences in the temples when the limiting component mates with the adjacent limiting recesses. This easily leads to low adjustment accuracy and is not conducive to achieving uniform gradient adjustment.

[0031] In one possible implementation, the limiting structure includes a meshing gear and a rack, wherein one of the second connecting portion and the third connecting portion is provided with the gear and the other is provided with the rack, and when the gear rotates relative to the rack, the temple moves relative to the hinge assembly along the length direction of the temple.

[0032] Using a rack and pinion transmission improves the stability of the relative movement between the temples and the hinge assembly. Furthermore, rack and pinion transmissions offer advantages such as a large transmission ratio, compact structure, and long service life. The smooth transmission also facilitates gradient adjustment of the temple position with high precision, better meeting practical usage needs.

[0033] In one possible implementation, the third connecting part is sleeved on the outside of the second connecting part, the second connecting part is provided with a first mounting cavity, the third connecting part is provided with the rack, the rack is located in the first mounting cavity, the gear is located in the first mounting cavity, and the gear is rotatable relative to the second connecting part;

[0034] The smart glasses also include a driving component. A first connecting hole is provided on the side wall of the first mounting cavity. A portion of the driving component extends into the first mounting cavity along the first connecting hole and connects with the gear to drive the gear to rotate.

[0035] This design allows the gears and rack to be protected through the first mounting cavity, thereby reducing the possibility of damage to the gears and rack.

[0036] In one possible implementation, the first connecting hole includes a first hole segment and a second hole segment that are connected to each other, and a plurality of second hole segments are spaced apart from the first hole segment and recessed radially outward from the hole wall of the first hole segment;

[0037] The driving component includes a driving section and a rotating section connected to each other. The driving section is located outside the first mounting cavity. The rotating section is connected to the gear. The rotating section includes a first mating section and a second mating section connected to each other. The second mating section protrudes radially along the first mating section. The first mating section can mate with the first hole section, and the second mating section can mate with the second hole section.

[0038] This design limits the movement of the drive components, reducing the possibility of accidental touches by users that could cause the temples to move relative to the frame, thus better meeting practical user needs.

[0039] In one possible implementation, the smart glasses include a reset member, and the rotating segment includes a second mounting cavity. Along the axial direction of the rotating segment, the opening of the second mounting cavity is located at one end of the rotating segment facing the interior of the first mounting cavity. The reset member includes an elastic member and an abutment member. One end of the elastic member is connected to the inner wall of the second mounting cavity, and the other end is connected to the abutment member. The abutment member can extend out of the second mounting cavity and abut against the side wall of the first mounting cavity along the axial direction of the rotating segment to drive the driving member to move in a direction away from the first mounting cavity.

[0040] During use, the user can press the drive component to move it closer to the first mounting cavity, thereby disengaging the second mating section from the second hole section and enabling the drive component to drive the gear to rotate. After the user adjusts the temple to the appropriate position, the reset component applies force to the drive component, causing it to move away from the first mounting cavity, resetting the drive component and allowing the second mating section to extend into the second hole section. During adjustment, the drive component can move axially along the first connecting hole.

[0041] In one possible implementation, one of the second connecting portion and the third connecting portion is provided with a second connecting hole, the second connecting hole being sleeved on the outside of the other, the depth of the second connecting hole being b, and 3 mm ≤ b ≤ 15 mm.

[0042] When the depth of the second connecting hole is less than 3 mm, the total adjustment travel between the temple and the hinge assembly is too small, resulting in a small total adjustment distance and thus limiting the adjustment range of the temple. When the depth of the second connecting hole is greater than 15 mm, the size of the mating part between the temple and the hinge assembly becomes larger, leading to an increase in the overall volume of the temple and hinge assembly. This, in turn, increases the overall size and weight of the smart glasses, affecting the user's wearing experience.

[0043] In one possible implementation, one of the second connecting portion and the third connecting portion is provided with a guide rail, and the other is provided with a mating portion, the mating portion engaging with the guide rail and being able to move along the guide rail.

[0044] This design improves the stability of the temples and hinge assembly during relative movement, and also helps to improve the relative positional accuracy of the temples and hinge assembly, making it easier for users to adjust the position of the temples.

[0045] This application provides a smart glasses solution, comprising a frame and temples, with the temples connected to the frame via a hinge assembly. The temples can move relative to the hinge assembly in a direction approaching or away from the frame, thereby changing the distance between the temple tips and the frame. This design allows adjustment of the distance between the temple tips and the frame by changing the temple length, thus meeting the needs of different users. Adjusting the relative position between the temples and the hinge assembly helps maintain the integrity of the temples and reduces the difficulty of placing electronic components (circuit circuits) within the temples.

[0074] To better understand the technical solutions in this specification, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0075] It should be understood that the described embodiments are merely some, not all, of the embodiments in this specification. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without inventive effort are within the scope of protection of this specification.

[0076] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0077] With the development of technology, intelligent wearable devices are being used more and more widely in our lives. Examples include augmented reality (AR) glasses and virtual reality (VR) glasses. Figure 1 As shown, Figure 1This is a schematic diagram of the smart glasses in the wearing state. Smart glasses typically include a frame 1, a hinge assembly, and temples 3. Temples 3 are connected to the frame 1 via the hinge assembly and can rotate relative to the frame 1 to adjust the posture of the smart glasses. When wearing, temples 3 can be rotated outwards so that they are approximately perpendicular to the frame 1, and then worn through the user's ears. When storing, temples 3 can be rotated inwards so that they are approximately parallel to the frame 1, thereby reducing the space occupied by the smart glasses and facilitating storage.

[0078] When different users wear smart glasses, their structural requirements for the smart glasses will vary due to differences in body shape. For example, the size requirement for the temple 3 will vary depending on the head circumference. When the user's head circumference is large, the distance L between the frame 1 and the end of the temple 3 needs to be relatively large. When the user's head circumference is small, the distance between the frame 1 and the end of the temple 3 needs to be relatively small.

[0079] To meet the diverse needs of different users for smart glasses, the temples 3 and frame 1 can be configured as adjustable. For details, please refer to [link / reference needed]. Figure 2 , Figure 2 This is a schematic diagram of the structure of smart glasses in related technologies. The temple 3 includes a first main body 301 and a second main body 302. The first main body 301 is connected to the frame 1 via a hinge assembly. The second main body 302 is connected to the first main body 301 and can move relative to the first main body 301, making the temple 3 a telescopic structure. In use, the length of the temple 3 can be adjusted by adjusting the relative position between the first main body 301 and the second main body 302, thereby changing the distance from the frame 1 to the end of the temple 3.

[0080] like Figure 2 As shown, taking the need to increase the distance between the end of the temple 3 and the frame 1 as an example, in the smart glasses shown in the figure, the length of one of the temples 3 has been adjusted. After adjustment, the length from the frame 1 to the end of the temple 3 is L1. The other temple 3 has not been adjusted, that is, it is in its initial state, and the length from the frame 1 to the end of the temple 3 is L2, and L1 > L2. By setting the temple 3 as a telescopic structure, users can adjust the temple 3 according to their own needs. By adjusting the length of the temple 3, the distance between the end of the temple 3 and the frame 1 is changed to accommodate different users. When wearing the glasses, users can adjust the temple 3 to a suitable length according to their own needs, thereby improving wearing comfort.

[0081] Typically, the temples 3 of smart glasses need to house electronic components such as circuit boards, wiring, and sensors. When the first main body 301 and the second main body 302 of the temples 3 are separately arranged, the aforementioned electronic components are respectively arranged in the first main body 301 and the second main body 302, and the electronic components in the first main body 301 are electrically connected to the electronic components in the second main body 302.

[0082] Compared to the integrated temple 3, the separate first main body 301 and second main body 302 are both smaller in size, resulting in less space for components such as circuit boards. This increases the difficulty of installing circuit boards and wiring. Furthermore, since the first main body 301 and second main body 302 of the temple 3 can move relative to each other, their relative positions may change during adjustment. This poses a risk of affecting the stability of the electrical connections between the electronic components in the first main body 301 and the electronic components in the second main body 302, thereby impacting the reliability of the smart glasses.

[0083] like Figure 2 As shown, in one possible implementation, the first main body portion 301 and the second main body portion 302 overlap along the thickness direction of the smart glasses, that is, in the wearing state, at least a portion of one of the first main body portion 301 and the second main body portion 302 is located above the other. Figure 2 In the illustrated scheme, the second main body 302 overlaps the top of the first main body 301.

[0084] This design can easily lead to gaps between the first main body 301 and the second main body 302 during use, affecting the stability of the fit.

[0085] To address the aforementioned technical problems, embodiments of this application provide smart glasses, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of a first embodiment of smart glasses provided in this application. The smart glasses may include a frame 1, a hinge assembly 2, and temples 3, wherein the temples 3 are rotatably connected to the frame 1 via the hinge assembly 2. The temples 3 can move relative to the hinge assembly 2 in a direction close to or away from the frame 1 (the direction of movement of the temples is as follows). Figure 3 As shown by the dashed arrow in the image, the temple 3 can move in a direction close to the frame 1 or in a direction away from the frame 1, thereby changing the distance L between the end of the temple 3 and the frame 1, and thus changing the distance between the wearing part 32 of the temple and the frame 1. The hinge assembly 2 and the temple 3 are provided with a limiting structure, which is used to restrict the movement of the temple 3 relative to the hinge assembly 2.

[0086] The solution provided in this application, by setting the hinge assembly 2 and temple 3 as an adjustable structure, can change the relative position between the temple 3 and the hinge assembly 2, thereby adjusting the relative position between the temple 3 and the frame 1. This allows adjustment of the distance L between the frame 1 and the end of the temple 3 without changing the length of the temple 3, enabling the smart glasses to adapt to users with different usage needs. Furthermore, in the solution provided in this application, the temple 3 does not need to be a separate structure. During adjustment, the temple 3 moves as a whole relative to the frame 1 and the hinge assembly 2, maintaining the integrity of the temple 3. This design reduces the difficulty of arranging circuit boards, wiring, electronic components, and other parts in the temple 3. During adjustment, the components located on the temple 3 can remain stationary relative to the temple 3; therefore, the stability of the electrical connections between the components is better, which is more in line with actual usage requirements.

[0087] The following section describes in detail the specific structure of the relative movement between the temple and the hinge assembly.

[0088] like Figure 4 As shown, Figure 4 This is an exploded view of a first embodiment of the smart glasses provided in this application. In one possible implementation, the hinge assembly 2 includes a first connecting portion 21 and a second connecting portion 22 connected to each other. The temple 3 includes a third connecting portion 31 and a wearing portion 32 connected to each other. The wearing portion 32 may be provided with an ear loop or other structure to facilitate user wearing. The first connecting portion 21 is rotatably connected to the frame 1. In use, the user can drive the temple 3 to rotate relative to the frame 1 to adjust the temple 3 to a suitable wearing angle. The second connecting portion 22 is sleeved with the third connecting portion 31 of the temple 3. The second connecting portion 22 and the third connecting portion 31 can move relative to each other in the sleeve direction, that is, the second connecting portion 22 and the third connecting portion 31 can move relative to each other along the length direction of the temple 3.

[0089] During connection, the second connecting part 22 can be sleeved on the outside of the third connecting part 31, or the third connecting part 31 can be sleeved on the outside of the second connecting part 22. By sleeved between the hinge assembly 2 and the temple 3, the contact area between the hinge assembly 2 and the temple 3 can be increased, thereby improving the stability of the connection between the hinge assembly 2 and the temple 3. Moreover, the sleeved connection can guide the movement of the temple 3 relative to the hinge assembly 2, thereby improving the stability of the relative movement between the temple 3 and the hinge assembly during adjustment, which is more in line with actual usage requirements.

[0090] like Figure 5 As shown, Figure 5This is a schematic diagram of the temple and hinge assembly of a first embodiment of the smart glasses provided in this application. In one possible implementation, the limiting structure includes a limiting member 4 and a limiting recess 5. In the second connecting portion 22 and the third connecting portion 31, one is provided with the limiting member 4, and the other is provided with at least two limiting recesses 5. Each limiting recess 5 is spaced apart along the length direction of the temple 3. The limiting member 4 can extend into different limiting recesses 5 to change the relative position of the temple 3 and the hinge assembly 2.

[0091] The spacing between each limiting recess 5 can be set according to actual needs. By cooperating with different limiting recesses 5, the relative position of the temple 3 and the hinge assembly 2 can be changed, thereby adjusting the relative position between the temple 3 and the frame 1. This allows the smart glasses to adapt to different user needs, improve wearing comfort and stability, reduce the possibility of the glasses falling off during use due to excessive distance between the temple 3 and the frame 1, and reduce the possibility of the glasses being unable to be worn due to insufficient distance between the temple 3 and the frame 1.

[0092] like Figure 6 , Figure 7 and Figure 8 As shown, Figure 6 This is a schematic diagram showing the first embodiment of the smart glasses provided in this application in a first state. Figure 7 This is a schematic diagram showing the first embodiment of the smart glasses provided in this application in a second state. Figure 8 This is a schematic diagram of the first embodiment of the smart glasses provided in this application in a third state. In one possible implementation, the limiting member 4 includes an elastic part 41 and a limiting part 42 connected to each other. The limiting part 42 can move in a direction close to or away from the limiting recess 5 so that the limiting part 42 can extend into the limiting recess 5 or disengage from the limiting recess 5.

[0093] When the position of the temple 3 needs to be adjusted, the limiting part 42 can be driven to move away from the limiting recess 5. The elastic part 41 is compressed, and the restoring force generated by the elastic part 41 can act on the limiting part 42, causing the limiting part 42 to tend to move towards the limiting recess 5. After the limiting part 42 disengages from the limiting recess 5, the temple 3 and the hinge assembly 2 are driven to move relative to each other to adjust the smart glasses. After being adjusted to a suitable position, the restoring force of the elastic part 41 is used to drive the limiting part 42 to move closer to the limiting recess 5, so that the limiting part 42 cooperates with the corresponding limiting recess 5 to limit the temple 3 and the hinge assembly 2, thus fixing the temple 3 and the hinge assembly 2 relatively.

[0094] like Figure 6 , Figure 7 and Figure 8As shown, in one possible implementation, the limiting member 4 is provided in the hinge assembly 2, the second connecting part 22 or the third connecting part 31 is provided with a mounting groove 221, one end of the elastic part 41 is connected to the inner wall of the mounting groove 221, and the other end is connected to the limiting part 42. The limiting part 42 can extend out of the mounting groove 221 and cooperate with the limiting recess 5, or the limiting part 42 can retract into the mounting groove 221 and release the limiting cooperation with the limiting recess 5.

[0095] The limiting part 42 is located on the side of the elastic part 41 facing the opening of the mounting groove 221, and at least a portion of the limiting part 42 can extend or retract relative to the opening of the mounting groove 221. When the limiting part 42 extends relative to the mounting groove 221, it can engage with the corresponding limiting recess 5 to restrict the relative movement of the temple 3 and the hinge assembly 2. When the limiting part 42 retracts relative to the mounting groove 221, it can disengage from the limiting recess 5, allowing the temple 3 to move relative to the hinge assembly 2, thereby adjusting the distance between the temple 3 and the frame 1. By providing the mounting groove 221, a portion of the limiting member 4 can be located within the mounting groove 221, thus limiting the space occupied by the limiting member 4. At the same time, the mounting groove 221 can also guide the movement of the limiting member 4 during movement, thereby improving the stability of the movement of the limiting member 4.

[0096] The limiting part 42 may be provided with a guide surface, which may be a spherical surface, an arc surface, an inclined surface, or other structures. The limiting part 42 may be a sphere, and the surface of the sphere may serve as the guide surface. The edge of the limiting recess 5 may contact the guide surface. When the smart glasses need to be adjusted, the user can apply external force to move the temple 3 relative to the hinge assembly 2. The edge of the limiting recess 5 abuts against the guide surface, causing the limiting part 42 to move away from the limiting recess 5, thereby compressing the elastic part 41 and causing the limiting part 42 to contract, thus releasing the limiting part 42 from limiting the temple 3 and the hinge assembly 2. The temple 3 is driven to move relative to the hinge assembly 2 by external force. Taking the need to increase the distance between the temple 3 and the frame 1 as an example... Figure 6 The state shown is the state of the smart glasses before adjustment. During the adjustment process, the state of the smart glasses is as follows: Figure 8 As shown. When the temple 3 moves to the desired position, the corresponding limiting recess 5 aligns with the limiting part 42. Under the restoring force of the elastic part 41, the limiting part 42 moves towards the limiting recess 5 and extends into the limiting recess 5 to limit the temple 3 and the hinge assembly 2. The state of the smart glasses is as follows. Figure 8As shown. The mounting groove 221 can be a cylindrical structure, the limiting part 42 can be a sphere, and the elastic part 41 can be a cylindrical spring. The diameters of the limiting part and the elastic part can both be in the range of 0.7 mm to 0.9 mm. The diameter of the mounting groove 221 can be set according to the structural dimensions of the limiting member 4. The limiting recess 5 can be a cylindrical recess, and its diameter can be the same as the diameter of the limiting part 42, or it can be in the range of 0.7 mm to 0.9 mm. The distance between adjacent limiting recesses 5 can be 3 mm. Four limiting recesses are provided, and the total adjustable range is 9 mm.

[0097] In one possible implementation, the elastic part 41 can be a spring, sheet metal, rubber, or other elastic component. The limiting part 42 can be a spherical, arc-shaped, wedge-shaped, or other similar structure.

[0098] like Figure 6 , Figure 7 and Figure 8 As shown, in one possible implementation, the third connecting part 31 is sleeved on the outside of the second connecting part 22, the limiting member 4 is disposed on the second connecting part 22, and the limiting recess 5 is disposed on the third connecting part 31.

[0099] Since the third connecting part 31 is sleeved on the outside of the second connecting part 22, setting the limiting member 4 on the inner surface of the third connecting part 31 would be difficult. Therefore, the limiting member 4 can be set on the second connecting part 22. Because the third connecting part 31 is sleeved on the outside, it will have a cavity. When the limiting member 4 is set on the third connecting part 31, it needs to be placed on the side wall of the cavity. The side wall thickness of the cavity is relatively small, making the depth of the mounting groove 221 shallow and difficult to set. Therefore, the limiting member 4 is usually set on the inner side of the second connecting part 22. The mounting groove 221 can be made on the outer surface of the second connecting part 22, which is easier to process. Furthermore, the radial dimension of the second connecting part 22 is usually larger than the wall thickness of the cavity, so the size of the mounting groove 221 can be relatively large to meet installation and usage requirements.

[0100] In one possible implementation, the limiting member 4 is disposed on the second connecting portion 22 of the hinge assembly 2, and the limiting recess 5 is disposed on the third connecting portion 31 of the temple 3. The third connecting portion 31 can be sleeved with the wearing portion 32, and the third connecting portion 31 is disposed inside the wearing portion 32. Along the length direction of the temple 3, the third connecting portion 31 is provided with a plurality of limiting recesses 5 at intervals. Figure 9 As shown, Figure 9This is an exploded view of the temple of the first embodiment of the smart glasses provided in this application. The third connecting part 31 and the wearing part 32 can be relatively independent components. After processing, the third connecting part 31 is installed on the wearing part 32. One of the wearing part 32 and the third connecting part 31 is provided with a limiting section 313, and the other is provided with a connecting section 321. The limiting section 313 can be a structure that protrudes radially along the temple 3, and the connecting section 321 can be a structure that is recessed radially along the temple 3. When the wearing part 32 is sleeved on the third connecting part 31, at least a portion of the limiting section 313 can extend into the connecting section 321 so that the wearing part 32 and the third connecting part 31 cooperate. The separate structure of the wearing part 32 and the third connecting part 31 can be processed independently during processing, which facilitates operations such as opening holes in the third connecting part 31 and reduces the processing difficulty. By setting the limiting section 313 and the connecting section 321, the contact area between the wearing part 32 and the third connecting part 31 can be increased, thereby improving the stability of their connection and reducing the possibility of relative rotation between the wearing part 32 and the third connecting part 31. In use, the limiting member 4 cooperates with the limiting recess 5 through the limiting part 42. When the user needs to adjust the position of the temple 3, the user drives the temple 3 to move relative to the hinge assembly 2. Since the limiting part 42 is a sphere, the spherical surface of its surface can serve as a guide surface. When the third connecting part 31 of the temple 3 moves relative to the second connecting part 22 of the hinge assembly 2, the limiting part 42 can disengage from the limiting recess 5, and the elastic part 41 is compressed. When the temple 3 is adjusted to the position required by the user, the limiting member 4 aligns with another limiting recess 5. The elastic part 41 recovers its deformation, and the restoring force of the elastic part 41 can act on the limiting part 42, driving the limiting part 42 to extend into the corresponding limiting recess 5, thereby limiting the relative position of the temple 3 and the hinge assembly 2.

[0101] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, Figure 10 This is a schematic diagram of a second embodiment of the smart glasses provided in this application. Figure 11 This is a schematic diagram showing the second embodiment of the smart glasses provided in this application in the first state. Figure 12 This is a schematic diagram showing the second embodiment of the smart glasses provided in this application in a second state. Figure 13This is a schematic diagram of the second embodiment of the smart glasses provided in this application, in a third state. In one possible implementation, the limiting structure includes a mating recess 6, a limiting recess 5, and a connector 7. The second connecting part 22 is provided with the mating recess 6, and the third connecting part 31 is provided with at least two limiting recesses 5. The limiting recesses 5 are spaced apart along the length direction of the temple 3. The mating recess 6 can communicate with any of the limiting recesses 5, and the connector 7 can extend into the limiting recesses 5 and the mating recess 6. The mating recesses 6 and the limiting recesses 5 that communicate with each other are detachably connected by the connector 7, thereby limiting the movement of the temple 3 relative to the hinge assembly 2. When the temple 3 moves relative to the hinge assembly 2, the mating recess 6 can communicate with different limiting recesses 5. The user can connect the mating recess 6 with the corresponding limiting recess 5 according to their own needs, and then set the connector 7 in the mating recess 6 and the limiting recess 5 to limit the movement of the temple 3 relative to the hinge assembly 2 during the use of the smart glasses. The connector 7 can be a screw, bolt, or other component, and can be a through hole, groove, or other structure when combined with the recess 6 and the limiting recess 5.

[0102] This design is easy to operate, allowing users to adjust the relative position between the temple 3 and the frame 1 during use.

[0103] Taking the need to increase the distance between temple 3 and frame 1 as an example, the state of the smart glasses before adjustment is as follows: Figure 11 As shown, the connector 7 is disassembled, and the contact connector 7 limits the second connecting part 22 and the third connecting part 31. At this time, the temple 3 can be driven to move relative to the frame 1, so that the temple 3 moves to a suitable position. At this time, the state of the smart glasses is as follows. Figure 12 As shown. Then, connector 7 is installed, which limits the movement of the second connecting part 22 and the third connecting part 31. The state of the smart glasses is as follows. Figure 13 As shown.

[0104] In one possible implementation, the second connecting part 22 is provided with a first thread, the third connecting part 31 is provided with a second thread, and the second connecting part 22 and the second connecting hole 311 are threadedly engaged.

[0105] By providing threaded structures on the second connecting part 22 and the third connecting part 31 respectively, the two connecting parts 22 and 31 can be easily fitted together. Simultaneously, the threaded connection improves the stability of the fit between the second connecting part 22 and the third connecting part 31. While connecting the temple 3 and the hinge assembly 2, it also guides the relative movement of the temple 3 relative to the hinge assembly 2, enhancing the stability of their relative movement. The threaded connection structure is relatively simple and easy to manufacture. Furthermore, the use of a threaded connection facilitates the installation and removal of the temple 3 by the user. During use, the temple 3 can be disassembled to connect with the hinge assembly 2 of different frames 1, allowing the temple 3 to match various frames 1. For storage, the temple 3 can be disconnected from the hinge assembly 2, i.e., the temple 3 and the frame 1 can be separated, which helps save storage space and better meets practical usage needs.

[0106] In one possible implementation, the distance between adjacent limiting recesses 5 is a, the lead of the first thread and the second thread is b, and a = nb, where n is a positive integer. The value of n can be 1, 2, 3, 4, etc.

[0107] The lead is the axial distance between adjacent corresponding points on the same helix in a thread, representing the distance the helix moves along the axis of the cylinder during one revolution. By ensuring that the distance between adjacent limiting recesses 5 is an integer multiple of the thread lead, users can easily control the adjustment distance during use. During manufacturing, the distance between the limiting recesses 5 and the thread lead can be designed according to requirements. Taking a=3, b=1.5, n=2 as an example, when adjusting the temple 3, the user can drive the temple 3 to rotate relative to the hinge assembly 2. After the temple 3 rotates two revolutions, the limiting member 4 engages with the new limiting recess 5, and the position of the temple 3 relative to the hinge assembly 2 changes. When the smart glasses have multiple limiting recesses 5, the temple 3 is adjusted to a new position every two revolutions driven by the user relative to the hinge assembly 2. Users can adjust the temple 3 by moving it closer to or further away from the frame 1 according to their needs. When n is a positive integer, the number of rotations of the temple 3 relative to the hinge assembly 2 during adjustment is an integer. That is, after the user rotates the temple 3 n times relative to the hinge assembly 2, the limiting part 42 can engage with another limiting recess 5. This design reduces the possibility of changes in the state of the temple 3 after adjustment. When n is not a positive integer, the position of the components on the temple 3 may shift after the user adjusts its position, potentially causing the smart glasses to malfunction and become unwearable. For example, the ear loop at the end of the temple 3 furthest from the frame 1 may shift during adjustment, making it unwearable.

[0108] like Figure 14 and Figure 15 As shown, Figure 14 This is a schematic diagram of a third embodiment of the smart glasses provided in this application. Figure 15 This is a partial cross-sectional view of a third embodiment of the smart glasses provided in this application. In one possible implementation, the limiting member 4 includes a limiting portion 42, which can be a buckle. The limiting member 4 can be integrally formed on the second connecting portion 22 or the third connecting portion 31.

[0109] This design allows the limiting component 4 to be molded directly during production, which can save on the installation process, thereby reducing the processing difficulty, improving processing efficiency, and better meeting actual usage needs.

[0110] like Figure 15 As shown, in one possible implementation, the second connecting part 22 is sleeved on the outside of the third connecting part 31, and the limiting member 4 is provided on the third connecting part 31. Along the circumference of the third connecting part 31, the third connecting part 31 is provided with at least two limiting parts 42, and the at least two limiting parts 42 can move closer to or further away from each other. Figure 16 This is a schematic diagram of the third connecting portion of the third embodiment of the smart glasses provided in this application. Figure 17 This is a schematic diagram of the second connecting portion of a third embodiment of the smart glasses provided in this application. In one possible implementation, the third connecting portion 31 may include two limiting portions 42, which may be located on opposite sides of the third connecting portion 31.

[0111] This design improves the stability of the fit between the limiting component 4 and the limiting recess 5, thereby reducing the possibility that the limiting component 4 may disengage from the limiting recess 5 during user use, causing the temple 3 to move relative to the hinge assembly 2 and changing the distance between the temple 3 and the frame 1.

[0112] like Figure 16As shown, in one possible embodiment, the limiting member 4 further includes at least two elastic arms, which can serve as elastic portions 41. The fixed end of the elastic arm is fixedly connected to the third beam connecting portion 31, and the limiting portion 42 is disposed at the free end of the elastic arm, protruding relative to the surface of the elastic arm. The limiting recess 5 can be a rectangular groove with a width of 0.8 mm to 1.2 mm and a length of 1.2 mm to 1.8 mm. The width of the limiting recess 5 can be 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1.0 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, etc., and the length can be 1.2 mm, 1.3 mm, 1.4 mm, 1.55 mm, 1.6 mm, 1.7 mm, 1.8 mm, etc. When the limiting part 42 engages with the limiting recess 5, the extent to which the limiting part 42 extends into the limiting recess 5 can be from 0.3 mm to 0.6 mm, specifically 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, or 0.6 mm. If the extent to which the limiting part 42 extends into the limiting recess 5 is too large, the limiting part 42 will not easily disengage from the limiting recess 5, making adjustment difficult. If the extent to which the limiting part 42 extends into the limiting recess 5 is too small, the engagement between the limiting part 42 and the limiting recess 5 is less stable, and the limiting part 42 may easily disengage from the limiting recess 5 during use.

[0113] In one possible implementation, the protrusion height of the third connecting portion 31 can be 3 mm to 4 mm. When limit members 4 are provided on both opposite sides of the third connecting portion 31, such as... Figure 16 As shown, the two limiting members 4 can be arranged symmetrically. Along the thickness direction of the third connecting portion 31, the distance between the top surfaces of the two limiting portions 42 is 3 mm to 4 mm. There can be a gap between the elastic portions 41 of the two limiting members 4 to reserve space for the deformation of the elastic portions 41, thereby reducing the possibility of interference between the two limiting members 4 during the deformation of the elastic portions 41.

[0114] In one possible implementation, the distance between adjacent limiting recesses 5 is a, and satisfies: 1 mm ≤ a ≤ 5 mm.

[0115] The distance between adjacent limiting recesses 5 can be 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, etc. The spacing between the limiting recesses 5 can be set according to requirements. Users can adjust the position of the temple 3 by engaging the limiting member 4 with different limiting recesses 5, thus allowing the smart glasses to meet the wearing needs of different users. When the distance between adjacent limiting recesses 5 is less than 1 mm, the distance is too small, increasing the manufacturing difficulty. Furthermore, the adjustment effect is not obvious when the distance between adjacent limiting recesses 5 is too small, resulting in low utilization of the limiting recesses 5. When the distance between adjacent limiting recesses 5 is greater than 5 mm, the distance is too large, causing excessive positional differences in the temple 3 when the limiting member 4 engages with each adjacent limiting recess 5. This can easily lead to low adjustment accuracy and is not conducive to achieving uniform gradient adjustment.

[0116] In one possible implementation, the length direction of the second connecting portion 22 is parallel to the length direction of the temple 3. The height direction of the second connecting portion 22 is parallel to the height direction of the smart glasses. The width of the second connecting portion 22 can be from 1.8 mm to 2.5 mm. The length of the second connecting portion 22 can be from 13 mm to 19 mm.

[0117] like Figure 18 and Figure 19 As shown, Figure 18 This is a schematic diagram of the fourth embodiment of the smart glasses provided in this application. Figure 19 This is a partial cross-sectional view of the fourth embodiment of the smart glasses provided in this application. In one possible implementation, the limiting structure includes a gear 222 and a rack 312 that are mutually cored. In the second connecting part 22 and the third connecting part 31, one is provided with a gear 222 and the other is provided with a rack 312. The gear 222 and the rack 312 cooperate. When the gear 222 rotates relative to the rack 312, the temple 3 moves relative to the hinge assembly 2 along the length direction of the temple 3.

[0118] By employing gear 222 and rack 312 for transmission, the stability of the relative movement between the temple 3 and the hinge assembly 2 can be improved. Furthermore, gear and rack transmission has advantages such as a large transmission ratio, compact structure, and long service life. The gear and rack transmission is relatively smooth, which facilitates gradient adjustment of the temple 3 during use, with high adjustment precision, better meeting practical usage requirements.

[0119] like Figure 19As shown, in one possible implementation, the third connecting portion 31 is sleeved on the outside of the second connecting portion 22. The second connecting portion 22 is provided with a first mounting cavity 223, and the third connecting portion 31 is provided with a rack 312. The rack 312 is located in the first mounting cavity 223. The gear 222 is located in the first mounting cavity 223 and is rotatable relative to the second connecting portion 22. The smart glasses also include a driving component 9. The side wall of the first mounting cavity 223 is provided with a first connecting hole 224, which communicates with the first mounting cavity 223. A portion of the structure of the driving component 9 extends into the first mounting cavity 223 along the first connecting hole 224 and connects with the gear 222 to drive the gear 222 to rotate. In use, the user can drive the gear 222 to rotate through the driving component 9, thereby causing the temple 3 to move relative to the hinge assembly 2 through the cooperation of the gear 222 and the rack 312.

[0120] This design allows the gear 222 and rack 312 to be protected through the first mounting cavity 223, thereby reducing the possibility of damage to the gear 222 and rack 312.

[0121] like Figure 20 As shown, Figure 20 This is a cross-sectional view of the second connecting portion of a fourth embodiment of the smart glasses provided in this application. In one possible implementation, the first connecting hole 224 includes a first hole segment 224a and at least one second hole segment 224b that are interconnected. When the first connecting hole 224 includes a plurality of second hole segments 224b, the second hole segments 224b are circumferentially spaced along the first hole segment 224a and are recessed radially outward from the hole wall of the first hole segment 224a. Figure 21 As shown, Figure 21 This is a schematic diagram of the driving component provided in an embodiment of this application. The driving component 8 includes a driving section 81 and a rotating section 82. The driving section 81 is located outside the first mounting cavity 223, and the rotating section 82 is used to extend into the first mounting cavity 223 through the first connecting hole 224 to connect with the gear 222. The connecting section 321 includes a first mating section 821 and a second mating section 822. The first mating section 821 is used to mate with the first hole section 224a, and the second mating section 822 is used to mate with the second hole section 224b. The second mating section 822 is connected to the first mating section 821 and protrudes radially along the first mating section 821. When the driving component 8 moves axially along the first connecting hole 224, the second mating section 822 can extend into or disengage from the second hole section 224b. When the second mating section 822 disengages from the second hole section 224b, the driving component 8 can drive the gear 222 to rotate to adjust the distance between the temple 3 and the frame 1. When the second mating section 822 is located in the second hole section 224b, the second mating section 822 is used to restrict the drive member 8 from driving the gear 222 to rotate.

[0122] This design limits the movement of the drive component 8, thereby reducing the possibility of accidental touches by the user that could cause the temple 3 to move relative to the frame 1, which is more in line with actual user needs.

[0123] like Figure 22 As shown, Figure 22 This is a cross-sectional view of the driving component provided in an embodiment of this application. In one possible implementation, the smart glasses include a reset member 83, and a rotating segment 82 includes a second mounting cavity 823. Along the circumferential direction of the rotating segment 82, the opening of the second mounting cavity 823 is located at one end of the rotating segment 82 facing the interior of the first mounting cavity 223. The reset member 83 is mounted in the second mounting cavity 823, and at least a portion of the reset member 83 extends out relative to the opening, for abutting against the sidewall of the first mounting cavity 223 along the axial direction of the rotating segment 82. The reset member 83 is used to drive the driving component 8 to move in a direction away from the first mounting cavity 223.

[0124] In use, the user can press the drive member 8 to move it towards the first mounting cavity 223, thereby disengaging the second mating section 822 from the second hole section 224b, allowing the drive member 8 to drive the gear 222 to rotate. After the user adjusts the temple 3 to a suitable position, the reset member 83 applies force to the drive member 8, causing it to move away from the first mounting cavity 223, resetting the drive member 8 and allowing the second mating section 822 to extend into the second hole section 224b. During adjustment, the drive member 8 can move axially along the first connecting hole 224.

[0125] like Figure 22 As shown, in one possible implementation, the reset member 83 includes an elastic member 831 and an abutment member 832 connected to each other. At least a portion of the abutment member 832 is capable of extending or retracting relative to the opening of the second mounting cavity 823. One end of the elastic member 831 is connected to the inner wall of the second mounting cavity 823, and the other end is connected to the abutment member 832. The abutment member 832 is capable of extending out of the second mounting cavity 823 and abutting against the side wall of the first mounting cavity 223 along the axial direction of the rotating segment 82, for driving the drive member 8 to move in a direction away from the first mounting cavity 223.

[0126] In use, when the user drives the drive member 8 to move axially towards the first mounting cavity 223 along the first connecting hole 224, the abutment member 832 can abut against the side wall of the first mounting cavity 223. As the drive member 8 moves towards the first mounting cavity 223, the elastic member 831 is gradually compressed, and at least a portion of the abutment member 832 can retract into the second mounting cavity 823. After the user has finished adjusting, the user can remove the force applied to the drive member 8, and the restoring force of the elastic member 831 will drive the drive chain to move away from the first mounting cavity 223, thereby resetting the drive member 8.

[0127] In one possible implementation, after the drive gear 222 rotates 0.7°, the rack 312 moves a distance of 3 mm along the length of the temple 3, and the total adjustable range can be 9 mm. The module of the gear 222 can be 0.4 mm, the number of teeth can be 8, and the pressure angle is 20°.

[0128] This design enables the automatic reset of the drive component 8 through a mechanical structure, which is simple to operate, low in cost, and more in line with actual user needs.

[0129] In one possible implementation, the depth of the second connecting hole 311 is b, and satisfies: 3 mm ≤ b ≤ 15 mm.

[0130] The depth of the second connecting hole 311 can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc. The depth of the second connecting hole 311 can be set according to requirements.

[0131] When the depth of the second connecting hole 311 is less than 3 mm, the total adjustment stroke between the temple 3 and the hinge assembly 2 is too small, resulting in a small total adjustment distance, which in turn limits the adjustment range of the temple 3. When the depth of the second connecting hole 311 is greater than 15 mm, the size of the mating part between the temple 3 and the hinge assembly 2 will be larger, resulting in an increase in the overall volume of the temple 3 and the hinge assembly 2, which in turn increases the overall size and weight of the smart glasses, affecting the user's wearing experience.

[0132] In one possible implementation, the second connecting portion is cylindrical, with a length of 18 mm to 24 mm and a diameter of 3 mm to 4 mm.

[0133] In one possible implementation, one of the second connecting portion 22 and the third connecting portion 31 is provided with a guide rail, and the other is provided with a mating portion. The mating portion engages with the guide rail and is movable along the guide rail. During adjustment, the mating portion can move along the guide rail.

[0134] This design improves the stability of the temple 3 and the hinge assembly 2 during relative movement, and also helps to improve the relative positional accuracy of the temple 3 and the hinge assembly 2, making it easier for users to adjust the position of the temple 3.

[0135] The smart glasses provided in this application embodiment can adjust the relative position between the temple 3 and the frame 1 by adjusting the relative position between the temple 3 and the hinge assembly 2, thereby enabling the smart glasses to meet the wearing needs of different users. Furthermore, it helps maintain the integrity of the temples during adjustment.
