Referring to fig. 1 to 2d, fig. 1 shows a schematic structure of a pair of smart glasses 100 according to an embodiment of the present disclosure, and fig. 2a to 2d show schematic structures of a pair of smart glasses 100 according to an embodiment of the present disclosure in different viewing angles when worn. When the smart glasses 100 are worn on the head 982 of the user 980, the user 980 can see the image presented by the lenses 240 of the smart glasses 100. In this embodiment, the smart glasses 100 are augmented reality smart glasses, and may display a virtual image for the user 980 while the user 980 views a real-world scene, and the user 980 may also interact with the virtual image to achieve an augmented reality effect.

It can be understood that the embodiment of the present application is described by taking the smart glasses 100 as the augmented reality smart glasses as an example, but some embodiments of the embodiment of the present application are not limited to the Augmented Reality (AR) smart glasses, and may also be other smart glasses, such as smart glasses for implementing a Virtual Reality (VR) effect or smart glasses for implementing a hybrid reality (MR) effect.

As shown in fig. 1-2 d, the smart glasses 100 include a frame 200 and a lens 240. The frame includes a frame body 220 and two legs 300 respectively disposed at two sides of the frame body 220. The lenses 240 are secured to the frame body 220. Each temple 300 may be provided with any of the embodiments described below, as well as possible embodiments.

Those skilled in the art will understand that the smart glasses 100 in the embodiment of the present application are described by taking a pair of glasses legs, that is, two glasses legs as an example, but the embodiment of the present application is not limited to the smart glasses using two glasses legs, and may also be a glasses frame or smart glasses using one glasses leg, or a glasses frame or smart glasses using the structure of the present application in one of the two glasses legs. The embodiment of the present application is not limited to smart glasses, and may be common glasses.

In addition, the pair of temples 300 are of symmetrical design and construction. The two temples 300 may have the same or different structures.

The structure of one embodiment of a temple 300 of the frame 200 of the smart eyewear 100 will be described in detail below with reference to fig. 3-15.

Fig. 3 to 5 show schematic structures of the smart glasses 100 in different viewing angles according to the embodiment of the present application, in which the rear leg part 600 of the temple 300 is in a position of a rotation angle of 0 ° and a stretching length of 0 with respect to the front leg part 500. Fig. 6 to 12 show a partial sectional view and a partial enlarged view of the smart glasses 100 of the embodiment of the present application, mainly illustrating a schematic structure of a region where the rear leg part 600 and the front leg part 500 of the temple 300 are connected. Fig. 13 to 15 show schematic structures of the smart glasses 100 in different viewing angles according to the embodiment of the present application, in which the rear leg part 600 of the temple 300 is in a position of a rotation angle of 90 ° and a stretching length of 0 with respect to the front leg part 500.

As shown in fig. 3 to 5, the temples 300 are of a two-step structure including a front leg part 500 and a rear leg part 600 which are sequentially arranged in a length direction of the temples 300. One end 510 of the front leg portion 500 is connected to the frame body 220 and one end 610 of the rear leg portion 600 is connected to the other end 520 of the front leg portion 500. As shown in fig. 3, the front leg portion 500 of the temple 300 is adjacent to the temple piece 300 for attachment to the frame body 220, and the rear leg portion 600 of the temple 300 is adjacent to the temple piece 300 on the right side of fig. 3. One end 510 of the front leg portion 500 is an end of the front leg portion 500 near and for connecting to the frame body 220, and the other end 520 of the front leg portion 500 is an end of the front leg portion 500 away from the frame body 220 and for connecting to the rear leg portion 600. One end 610 of the rear leg portion 600 is an end of the rear leg portion 600 that is used to connect the front leg portion 500, and the other end 620 of the rear leg portion 600 is an end of the rear leg portion 600 that is distal from the front leg portion 500.

The rear leg portion 600 includes a straight section 630 and a bent section 640 formed integrally and arranged in this order along the length direction of the rear leg portion 600, one end 610 of the rear leg portion 600 is located at the straight section 630, and the other end 620 of the rear leg portion 600 is located at the bent section 640. The curved section is for gripping with the head of the user. That is, the end of the straight section 630 remote from the curved section 640 constitutes one end 610 of the rear leg portion 600, and the end of the curved section 640 remote from the straight section 630 constitutes the other end 620 of the rear leg portion 600.

The front leg part 500 and the rear leg part 600 of the temples 300 may be made of a light material to reduce the weight as much as possible. For example, but not limited to, a lightweight material such as plastic, aluminum alloy, titanium alloy, or carbon fiber may be used while maintaining sufficient strength.

As shown in fig. 6-12, the rear leg portion 600 is movable back and forth in the direction of the axis O relative to the front leg portion 500 to enable the rear leg portion 600 to be switched between different multiple movement positions relative to the front leg portion 500. When the rear leg portion 600 is moved to a desired movement position with respect to the front leg portion 500, relative movement between the rear leg portion 600 and the front leg portion 500 in the direction along the axis O can be restricted, thereby achieving positioning of the rear leg portion 600 with respect to the front leg portion 500 in the direction along the axis O. The axis O means a center line which is connected to the front leg part 500 and the rear leg part 600 through the connecting part and extends linearly in a length direction of the temple.

The rear leg portion 600 moves back and forth in the direction along the axis O relative to the front leg portion 500 under the action of an external moving force in the direction along the axis O greater than a predetermined moving force, and when moved to any one of a plurality of moving positions where the external moving force is less than the predetermined moving force, the rear leg portion 600 is positioned in the direction of the axis O relative to the front leg portion 500. Thereby enabling the rear leg part 600 to be switched between different plural moving positions relative to the front leg part 500, i.e., enabling the moving position of the rear leg part 600 relative to the front leg part 500 in the direction along the axis O to be adjusted, thereby enabling the position of the rear leg part 600 relative to the front leg part 500 in the direction of the axis O and the length of the temple 300 to be adjusted. When the intelligent glasses 100 with the glasses legs 300 are worn, the user groups with different distances from eyes to ears can be adjusted and used, so that the wearing compatibility of users with different head types and head circumferences can be further improved, the user groups are increased, and the user groups which can be suitable for the user groups are wider.

When the rear leg portion 600 is moved in the direction of the axis O to a moving position desired by the user with respect to the front leg portion 500, relative movement between the rear leg portion 600 and the front leg portion 500 in the direction of the axis O can be restricted, i.e., relative positioning between the rear leg portion 600 and the front leg portion 500 in the direction of the axis O can be achieved, so that the rear leg portion 600 can be fixed in the desired moving position in the direction of the axis O with respect to the front leg portion 500, ensuring reliability of adjustment.

The rear leg part 600 is moved to different moving positions in the direction of the axis O with respect to the front leg part 500, enabling the temples 300 to be drawn differently in length. As shown in fig. 7, when the rear leg part 600 is moved to the head end moving position relative to the front leg part 500 in the direction of the axis O, the stretched length of the temple 300 is 0, i.e., the stretched length is at the minimum position. When the rear leg part 600 is moved to the caudal end movement position with respect to the front leg part 500 in the direction of the axis O, the stretched length of the temple 300 is at the maximum position.

It will be understood by those skilled in the art that the connection of the other end 520 of the front leg section 500 to one end of the rear leg section 600 may also be configured such that the rear leg section 600 can move back and forth in the direction of the axis O relative to the front leg section 500 between the head end moved position to the aft end moved position under an external moving force in the direction of the axis O greater than a predetermined moving force, and the rear leg section 600 can be positioned in the direction of the axis O relative to the front leg section 500 when moved to any one of the moved positions between the head end moved position to the aft end moved position and the external moving force is less than the predetermined moving force. This allows the adjustment of any displacement position. In addition, the connection of the other end 520 of the front leg portion 500 with one end of the rear leg portion 600 is provided such that the rear leg portion 600 can also rotate about the axis O in the forward or reverse direction with respect to the front leg portion 500 under the action of an external rotational force about the axis O greater than a predetermined rotational force, so that the rear leg portion 600 can be switched between a plurality of different rotational positions with respect to the front leg portion 500, i.e., the rotational position of the rear leg portion 600 with respect to the front leg portion 500 in the direction of rotation about the axis O can be adjusted. When the rear leg portion 600 is rotated to a desired rotational position with respect to the front leg portion 500 and the external rotational force is less than the predetermined rotational force, the relative rotational movement between the rear leg portion 600 and the front leg portion 500 about the axis O can be restricted, thereby achieving the relative positioning immobility between the rear leg portion 600 and the front leg portion 500 in the direction of rotation about the axis O.

Rotation of the rear leg portion 600 about the axis O to different rotational positions relative to the front leg portion 500 enables the rear leg portion 600 to be clamped to different parts of the user's head. As shown in fig. 3-12, when the rear leg portion 600 is rotated about the axis O relative to the front leg portion 500 to the head end rotated position 952 (see fig. 12), the rear leg portion 600 is supported and clamped on the ears of the user's head with the clamping force of the rear leg portion 600 with the head at a minimum position. As shown in fig. 13-15, when the rear leg portion 600 is rotated about the axis O relative to the front leg portion 500 to the caudal rotated position 954 (see fig. 12), the rear leg portion 600 is supported on and clamped to the brain of the user's head with the clamping force of the rear leg portion 600 with the head at a maximum position.

When the glasses frame 200 or the smart glasses 100 adopting the glasses legs 300 is worn, the rotation position of the rear leg part 600 relative to the front leg part 500 in the direction rotating around the axis O can be adjusted, so that the part of the rear leg part 600 clamped with the head of a user can be adjusted, the clamping force and the wrapping performance of the smart glasses 100 can be adjusted, the rear leg part 600 can be adjusted to the rotation position with smaller clamping force and wrapping performance of the smart glasses 100 in a common scene, and the wearing stability and comfort requirements of the user in the common scene are ensured. Also, the rear leg part 600 can be adjusted to a rotational position where the clamping force and the wrapping property of the glasses are relatively large in the sports scene, so that the wearing stability, comfort and safety of the user in the sports scene can be balanced. That is to say, the smart glasses 100 using the glasses legs 300 can meet the use requirements of the same user in different scenes, and the use scenes are increased, that is, the adaptability of the use scenes is wide.

Meanwhile, the rotating position of the rear leg part 600 relative to the front leg part 500 in the direction rotating around the axis O is adjusted, so that the part of the rear leg part 600 clamped with the head of the user is adjusted, the requirements of stability and comfort when the user with different head types and head circumference widths wears the head can be met, the wearing compatibility of the user with different head types and head circumferences can be improved, the user group is increased, and the user group which can be applied to the head support is wider. And the temples 300 have a simple structure and a low cost.

Also, the moving position of the rear leg part 600 with respect to the front leg part 500 in the direction along the axis O and the rotational position of the rear leg part 600 with respect to the front leg part 500 in the direction of rotation about the axis O can be adjusted individually, and by coordinating the adjustment of the moving position and the adjustment of the rotational position, the user can adjust the wearing of the smart glasses 100 to a most comfortable position.

It will be understood by those skilled in the art that the connection of the other end 520 of the front leg section 500 to one end 610 of the rear leg section 600 may also be configured such that the rear leg section 600 is capable of moving in a forward or reverse direction about the axis O relative to the front leg section 500 between the head-end rotated position to the aft-end rotated position under an external rotational force greater than a predetermined rotational force, and the rear leg section 600 is capable of being positioned in a fixed position relative to the front leg section 500 in the direction of rotation about the axis O when moved to any one of the rotated positions between the head-end rotated position to the aft-end rotated position and the external rotational force is less than the predetermined rotational force. This allows for adjustment of any rotational position.

The structure of the movement position adjustment of the temples 300 will be described and explained below.

As shown in fig. 3 to 12, the connection of the other end 520 of the front leg part 500 to the one end 610 of the rear leg part 600 is made through the temple-posture adjusting means 400. As shown in fig. 3 and 7-10, the temple-posture adjusting means 400 includes a barrel 560, a rod 650, and an adaptor member 700. The cylinder 560 is provided with a housing chamber 530 extending in the direction of the axis O. The rod-shaped body 650 extends into the accommodation chamber 530 in the direction of the axis O, and one end of the rod-shaped body 650 is a free end. The cylinder 560 is formed for the rear section of the front leg part 500 including the other end 520, and the rod 650 is formed to extend from one end 610 of the rear leg part 600 in a direction axially away from the rear leg part 600 in a smaller lateral dimension than the one end 610. That is, the cylinder 560 is integral with respect to the front leg part 500, and the rod 650 is integral with respect to the rear leg part 600. In this embodiment, the cross-sectional dimension of the rod-shaped body 650 is smaller than the cross-sectional dimension of the rear leg portion 600.

It should be noted that the tubular body 560 and the rod-shaped body 650 may be formed in such a manner that, for example, the tubular body 560 is formed as a front section of the rear leg portion 600 including the one end 610, and the rod-shaped body 650 is formed as a front leg portion 500 extending from the other end 520 of the front leg portion 500 in a direction away from the front leg portion 500 in a direction along the axis with a smaller lateral dimension than the other end 520. That is, the cylinder 560 is integral with respect to the rear leg portion 600, and the rod 650 is integral with respect to the front leg portion 500.

Of course, it will be understood by those skilled in the art that the temple-posture adjusting means 400 may be separated from the temple 300 as a separate temple-posture adjuster having a moving-position adjusting function and a rotating-position adjusting function, for example, one end of the cylindrical body 560 is configured to be fixedly coupled and detachably coupled to the other end 520 of the front leg part 500, and the other end of the rod body 650 is configured to be fixedly coupled and detachably coupled to one end 610 of the rear leg part 600; alternatively, one end of the cylindrical body 560 is configured to be fixedly and removably attached to one end 610 of the rear leg section 600 and the other end of the rod-shaped body 650 is configured to be fixedly and removably attached to the other end 520 of the front leg section 500.

As shown in fig. 7, the adapter member 700 extends along the direction of the axis O, and the adapter member 700 is sleeved on the outer wall surface of the rod-shaped body 650 and is sleeved in the accommodating chamber 530 of the cylindrical body 560. The adapter member 700 is fixed relative to the cartridge 560 in a direction along the axis O. A movement positioning unit 800 is formed between the outer wall surface of the rod 650 and the inner wall surface of the adaptor member 700. The cylindrical body 560 and the adapter member 700 are relatively fixed in the direction along the axis O so that the rod body 650 can move in the direction along the axis O relative to the cylindrical body 560 and the adapter member 700. That is, when the rod-shaped body 650 moves in the direction of the axis O with respect to the cylinder-shaped body 560, the rod-shaped body 650 can also move in the direction of the axis O with respect to the adapter member 700, thereby causing the rear leg portion 600 to move in the direction of the axis O with respect to the front leg portion 500.

When the rod-shaped body 650 moves to a desired moving position relative to the cylindrical body 560 and the adapter member 700, the moving positioning assembly 800 can limit the relative moving motion between the rod-shaped body 650 and the cylindrical body 560 in the direction along the axis O, can ensure the relative fixation of the rod-shaped body 650 and the cylindrical body 560 in the direction along the axis O, and can better ensure that the rod-shaped body 650 can be kept in the moving position state, so that the temple 300 can be fixed at the adjusted moving position, thereby ensuring the reliable positioning at the moving position and improving the use reliability. When abrasion is generated under the condition of multiple adjustment and use, the adapter part 700 is directly replaced, and the use cost is low.

When the rod-shaped body 650 is moved to a movement position among a plurality of movement positions with respect to the cylinder 560, if the cylinder 560 or the rod-shaped body 650 is subjected to an external movement force less than or equal to a predetermined movement force at the movement position or is canceled, the rod-shaped body 650 is positioned in the direction of the axis O with respect to the cylinder 560. If the cylinder 560 or the rod 650 is subjected to an external moving force greater than a predetermined moving force at the moving position, the rod 650 moves in the direction of the axis O with respect to the cylinder 560. It will be understood by those skilled in the art that the predetermined moving force is an interaction force between two components cooperating with each other in a moving direction, and may be, for example, a friction force or an elastic force. In this embodiment, the mobile positioning assembly 800 is capable of providing the predetermined movement force.

In the present embodiment, the material of the adapter member is a Polyoxymethylene (POM) thermoplastic crystalline polymer. The adapter part made of the material has high strength and rigidity, good elasticity and good abrasion resistance. It will be understood by those skilled in the art that the material of the adapter component is not limited to the polyoxymethylene thermoplastic crystalline polymer, and other materials with good elasticity may be used, which does not limit the scope of the present application.

In the present embodiment, as shown in fig. 7, a stepped chamber 540 having a stepped diameter larger than that of the accommodation chamber 530 of the other portion is formed in the cylindrical body 560. The adapter member 700 is located within the indexing chamber 540 and is capable of rotating within the indexing chamber 700 about axis O relative to the cartridge 560. The stepped wall surfaces 550 at both ends of the stepped chamber 540 can limit relative movement between the cartridge 560 and the adapter member 700 in the direction along the axis O. That is, both ends of the adapter member 700 in the direction of the axis O abut against the stepped wall surfaces 550 of both ends of the stepped chamber 540, respectively. Thereby, the cylindrical body 560 and the adapter member 700 can be relatively fixed in the direction of the axis O.

In some alternative embodiments, the movement positioning assembly 800 may be formed between an outer wall surface of the adapter member 700 and an inner wall surface of the cylinder 560, the rod-shaped body 650 and the adapter member 700 being relatively fixed in the direction of the axis O, the rod-shaped body 650 and the adapter member 700 being movable as a whole in the direction of the axis O relative to the cylinder 560. When the rod-shaped body 650 and the adapter member 700 are integrally moved to a desired movement position with respect to the cylinder 560, the movement positioning assembly 800 can restrict the rod-shaped body 650 and the adapter member 700 from moving with respect to the cylinder 560, so that the relative positioning of the rod-shaped body 650 and the cylinder 560 in the direction along the axis O can be realized, and the relative positioning of the rear leg portion 600 and the front leg portion 500 in the direction along the axis O can be realized, thereby ensuring reliable positioning in the movement position.

Referring to fig. 7-9, the mobile positioning assembly 800 includes a first resilient tab 810 and a plurality of first slots 820. The first elastic protrusion 810 protrudes from the surface of the adaptor member 700 that is engaged with the rod 650, i.e., the inner wall surface of the adaptor member 700. The plurality of first engaging grooves 820 are disposed on the outer wall surface of the rod-shaped body 650 and are recessed inward with respect to the outer wall surface of the rod-shaped body 650, and the plurality of first engaging grooves 820 are spaced apart along the direction of the axis O. When the rod 650 moves to a plurality of different moving positions with respect to the cylindrical body 560, the first engaging grooves 820 corresponding to the plurality of moving positions engage with the first elastic engaging protrusions 810, respectively, to restrict relative movement between the cylindrical body 560 and the rod 650 in the direction of the axis O.

The rod-shaped body 650 moves to a plurality of different moving positions relative to the adaptor member 700 and the cylindrical body 560, and the plurality of first locking grooves 820 are respectively locked with the first elastic locking protrusions 810, so that the relative positioning between the adaptor member 700 and the rod-shaped body 650 at the corresponding moving position in the direction of the axis O can be ensured, the relative positioning between the rod-shaped body 650 and the cylindrical body 560 in the direction of the rotation of the axis O can be realized, that is, the multi-stage adjustment of the moving positions between the rear leg part 600 and the front leg part 500 in the direction of the axis O can be realized, and the operation is convenient, flexible and reliable. And the structure is simple, and the production cost is low.

The first elastic locking protrusion is a conventional fastener that maintains the locking relationship by an elastic force, and the locking relationship can be released by applying an external force greater than the elastic force. In this embodiment, the elastic force generated between the first elastic locking protrusion and the first locking groove is the predetermined moving force at the locking position.

When the user wears the smart glasses 100, as shown in fig. 7, when an external moving force greater than a predetermined moving force is applied to the rod 650 in the direction of the axis O, the first elastic latching protrusion 810 can be elastically deformed, slide out of the currently engaged first latching groove 820, move into another first latching groove 820, and engage with another first latching groove 820, and when the external moving force is smaller than the predetermined moving force or is cancelled, the temple 300 can be reliably positioned at the adjusted moving position by the engaging force of the first elastic latching protrusion 810 and the first latching groove 820.

When the rear leg portion 600 moves to the head end moving position relative to the front leg portion 500 in the direction of the axis O, the first engaging groove 820 at the head end of the plurality of first engaging grooves 820 is engaged with the first elastic engaging protrusion 810, and one end of the rear leg portion 600 is in contact with one end of the adjacent cylindrical body 560 (in the present embodiment, the other end 520 of the front leg portion 500), and at this time, the stretched length of the temple 300 is 0, that is, the stretched length is at the minimum position.

When the rear leg part 600 is moved to the end moving position relative to the front leg part 500 in the direction of the axis O, the first locking groove 820 of the end of the plurality of first locking grooves 820 is engaged with the first elastic locking protrusion 810, and one end of the rear leg part 600 and one end of the adjacent cylindrical body 560 (in this embodiment, the other end 520 of the front leg part 500) are spaced apart in the direction of the axis O, and at this time, the stretched length of the temple 300 is at the maximum position.

In this embodiment, the first card slot 820 has four. It should be noted that the number of the first card slots 820 is not limited to four, and may be set appropriately according to actual requirements, and the scope of protection of the present application is not limited herein.

As shown in fig. 7 and 10, a wall surface of a portion of the peripheral wall of the adapter member 700, where the first elastic clamping protrusion 810 is disposed, has a concave portion 710 which is recessed inward in the radial direction of the adapter member 700, and the concave portion 710 extends to positions near both ends of the adapter member 700 in the length direction of the adapter member 700. Meanwhile, the hollow structure 720 is adopted in the adapter part 700 on the wall close to the first elastic clamping protrusion 810 in the circumferential direction of the adapter part 700, so that a bridge-shaped structure with an axial trend is formed, and the first elastic clamping protrusion 810 is arranged on the bridge-shaped structure with the axial trend. Therefore, the part of the peripheral wall of the adapting component 700, which is provided with the first elastic clamping protrusion 810, is easy to generate elastic deformation, so that under the condition of certain acting force, the first elastic clamping protrusion 810 can generate elastic deformation, and further can slide out and rotate to the other first clamping groove 820 from one first clamping groove 820 clamped with each other, and the operability of adjusting the moving position of the back leg part 600 by a user is ensured.

In some alternative embodiments, the mobile positioning assembly 800 may be formed directly between the outer wall surface of the rod-shaped body 650 and the inner wall surface of the barrel-shaped body 560. For example, the first elastic locking protrusion 810 of the mobile positioning assembly 800 may be disposed on the outer wall surface of the rod-shaped body 650, and the corresponding plurality of first locking grooves 820 may be disposed on the inner wall surface of the cylindrical body 560; alternatively, the first elastic locking protrusion 810 of the mobile positioning assembly 800 may be disposed on the inner wall surface of the cylindrical body 560, and the corresponding plurality of first locking grooves 820 may be disposed on the outer wall surface of the rod-shaped body 650.

As shown in fig. 7-10, the temple 300 further includes a stop 920, the stop 920 including a stop fastener 922 and a stop slot 924. The limiting groove 924 is disposed on the outer wall surface of the rod 650 and extends in the direction of the axis O. The retaining fastener 922 is fixed to and detachably connected to the adapting member 700, and the retaining fastener 922 extends into the retaining groove 924.

When the rod 650 moves relative to the adapter member 700 in the direction of the axis O, the limit fastener 922 can move within the limit groove 924. When the rod-shaped body 650 is slid to a position where the limit fastener 922 abuts against the end of the limit groove 924, the movement of the rod-shaped body 650 in the direction of the axis O toward the rear (i.e., toward the right in fig. 7) with respect to the adapter member 700 is limited. This ensures that the fastener 922 is retained and interferes with the relative movement of the rod 650 and the cartridge 560 in the direction of the axis O, whilst preventing the rod 650 from slipping out of the cartridge 560. So that the rear leg part 600 can be prevented from slipping out of the front leg part 500 in the case where excessive force is applied when the user operates. Thus, the reliability and safety of use are improved.

In some alternative embodiments, the limiting device 920 may include a limiting boss 926 (see fig. 19), the limiting boss 926 protrudes from the cylindrical body 560, and when the rod-shaped body 650 moves backward in the direction of the axis O relative to the cylindrical body 560 to a position abutting against the limiting boss 926, the backward movement of the rod-shaped body 650 relative to the adapting member 700 in the direction of the axis O is limited.

The structure of the rotational position adjustment of the temples 300 will be described and explained below.

Referring to fig. 8-10, a rotational positioning assembly 900 is formed between the inner wall surface of the cylindrical body 560 and the outer wall surface of the adapter member 700. And the adapter member 700 is fixed relative to the rod 650 in the direction of rotation about the axis O. The rod-shaped body 650 and the adapter member 700 are relatively fixed in the direction of rotation about the axis O, so that the rod-shaped body 650 can rotate relative to the cylindrical body 560 in conjunction with the rotation of the adapter member 700 about the axis O. That is, when the rod body 650 rotates in the direction of rotating about the axis O with respect to the cylinder body 560, the rod body 650 can rotate in the direction of rotating about the axis O with respect to the cylinder body 560 in conjunction with the adaptor member 700.

The limit fastener 922 abuts against both sides of the limit groove 924 in the direction of rotation about the axis O, so that the rod-shaped body 650 and the adapter member 700 are relatively fixed in the direction of rotation about the axis O. This enables further limiting of the relative rotational movement between the adaptor member 700 and the rod 650 in the direction of rotation about the axis O.

Further, the mating surface between the outer wall surface of the rod-shaped body 650 and the inner wall surface of the adapter member 700 is a fool-proof surface to limit the relative rotation between the adapter member 700 and the rod-shaped body 650. The fool-proofing structure is better able to limit the relative rotational movement between the adapter member 700 and the rod-shaped body 650 in the direction of rotation about the axis O. In the present embodiment, the portion of the rod-shaped body 650 that mates with the adaptor member 700 is configured in the shape of a semi-cylinder. It should be noted that the foolproof structure of the present application is not limited to the semi-cylindrical shape, and the portion of the rod 650 that mates with the adapter 700 may be configured to have an at least partially asymmetrical shape, such as a non-cylindrical shape, for example, a polyhedron, a cuboid, a cube, etc. And corresponding mounting holes of substantially the same shape and size may be provided at corresponding mounting locations of the adaptor member 700 for insertion of the mounting rod 650. The correct mounting orientation of the rod 650 is determined based on the asymmetrically shaped mounting hole, thereby further providing a foolproof mounting feature.

The rotational positioning assembly 900 is capable of limiting relative rotational movement of the rod 650 and the adapter member 700 relative to the cartridge 560 in a direction of rotation about the axis O when the rod 650 and the adapter member 700 are rotated to a desired rotational position relative to the cartridge 560. The relative positioning of the adapting component 700 and the cylindrical body 560 in the direction of rotating around the axis O is realized through the rotary positioning assembly 900, so that the reliable positioning at the rotating position is ensured, the wearing stability at the position state is further better ensured, and the use reliability is improved. When abrasion is generated under the condition of multiple adjustment and use, the adapter part 700 is directly replaced, and the use cost is low.

When the rod-shaped body 650 is rotated to one of a plurality of rotational positions with respect to the cylinder 560, if the cylinder 560 or the rod-shaped body 650 is subjected to an external rotational force less than or equal to a predetermined rotational force at the rotational position or is cancelled, the rod-shaped body 650 and the adapter member 700 can be positioned in the direction of rotation about the axis O with respect to the cylinder 560. If the cartridge 560 or the rod 650 is subjected to an external rotational force greater than the predetermined rotational force at that rotational position, the rod 650 and the adaptor part 700 can rotate about the axis relative to the cartridge 560. It will be understood by those skilled in the art that the predetermined rotational force is an interaction force between two components engaged with each other in a rotational direction, and may be, for example, a frictional force or an elastic force, etc. In this embodiment, the rotational positioning assembly 900 is capable of providing the predetermined rotational force.

In the present embodiment, the adaptor member 700 serves as both a movement adaptor member for performing movement position adjustment and a rotation adaptor member for performing rotation position adjustment, and the rotation adaptor member and the movement adaptor member are the same member. Of course, the mobile adapter part and the rotary adapter part may also be designed as non-integral parts, for example, as separate parts that are fixedly connected to each other.

When it is necessary to adjust the movement position of the rod body 650 in the direction of the axis O with respect to the cylinder body 560, a force is applied to the rod body 650 or the cylinder body 560 in the direction of the axis O, and the rod body 650 moves in the direction of the axis O with respect to the adapter member 700 and the cylinder body 560 as a whole, thereby adjusting the movement position between the rod body 650 and the cylinder body 560 in the direction of the axis O.

When it is necessary to adjust the rotational position of the rod 650 relative to the cylindrical body 560 in the direction of rotation about the axis O, a force applied to the rod 650 or the cylindrical body 560 in the direction of rotation about the axis O causes the rod 650 to rotate integrally with the adapter 700 relative to the cylindrical body 560 about the axis O, thereby adjusting the rotational position between the rod 650 and the cylindrical body 560 in the direction of rotation about the axis O.

That is, the glasses legs 300 having the above structure can adjust the moving position and the rotating position independently more conveniently and reliably, so as to ensure the cooperative action thereof, avoid the mutual interference between the moving position adjustment and the rotating position adjustment, and improve the adjustability of the user operation. Through the cooperation of the rotational positioning assembly 900 and the mobile positioning assembly 800, the independent adjustment of the mobile position and the independent adjustment of the rotational position can be more reliably achieved, so that the smart glasses 100 can be adjusted to the most comfortable position.

In some alternative embodiments, the rotational positioning assembly 900 may be formed between an inner wall surface of the adapter member 700 and an outer wall surface of the rod-shaped body 650, and the barrel-shaped body 560 and the adapter member 700 are arranged to be relatively fixed in a direction of rotation about the axis O, such that the rod-shaped body 650 can rotate integrally about the axis O with respect to the adapter member 700 and the barrel-shaped body 560. Upon rotation of the rod 650 relative to the adaptor member 700 and the cartridge 560 to a desired rotational position, the rotational positioning assembly 900 is able to limit relative rotation between the rod 650 and the adaptor member 700 in a rotational direction about the axis O, thereby enabling relative fixation of the rod 650 and the cartridge 560 in a rotational direction about the axis O, thereby ensuring reliable positioning at that rotational position.

Referring to fig. 7-12, the rotational positioning assembly 900 includes a second resilient tab 910 and a plurality of second detents 912. The second elastic locking protrusion 910 is protruded from an outer wall surface of the adaptor member 700, and the plurality of second locking grooves 912 are provided on an inner wall surface of the cylindrical body 560, are recessed from the inner wall surface of the cylindrical body 560 in a radial direction of the cylindrical body 560 toward the outer wall surface of the cylindrical body, and are spaced apart from each other in a direction rotating about the axis O. When the rod-shaped body 650 is rotated to a plurality of different rotational positions in conjunction with the adaptor member 700 with respect to the cylindrical body 560, the second engaging grooves 912 corresponding to the plurality of rotational positions are engaged with the second elastic engaging protrusions 910, respectively, so as to restrict relative rotation between the cylindrical body 560 and the rod-shaped body 650 in a direction of rotation about the axis O.

The rod-shaped body 650 rotates together to a plurality of different rotation positions relative to the cylindrical body 560 in a linkage manner, and the second locking grooves 912 corresponding to the plurality of rotation positions are respectively engaged with the second elastic locking protrusions 910, so that the relative fixation of the adapter member 700 between the corresponding rotation position and the cylindrical body 560 in the direction of rotating around the axis O can be ensured, the relative fixation of the rod-shaped body 650 between the corresponding rotation position and the cylindrical body 560 in the direction of rotating around the axis O can be realized, that is, the multi-stage adjustment of the rotation position between the rear leg part 600 and the front leg part 500 in the direction of rotating around the axis O can be realized, and the operation is convenient, flexible and reliable. And the structure is simple, and the production cost is low.

The second elastic locking protrusion is a conventional fastener that maintains the locking relationship by an elastic force, and the locking relationship can be released by applying an external force greater than the elastic force.

As shown in fig. 9 and 12, an inner wall surface of a portion of the peripheral wall of the adapter member 700, on which the second elastic locking protrusion 910 is provided, has a recess 730 that is recessed toward an outer wall surface of the adapter member in a radial direction of the adapter member 700. Therefore, the part of the peripheral wall of the adapter 700, where the second elastic clamping protrusion 910 is disposed, is easily elastically deformed, so that under the condition of a certain acting force, the second elastic clamping protrusion 910 can elastically deform, and further can slide out from one second clamping groove 912 to rotate into the other second clamping groove 912, thereby ensuring the operability of adjusting the rotating position of the rod-shaped body 650 by a user.

Further, as shown in fig. 7 and 9, a second elastic snap 910 is provided on an outer wall surface of one end portion of the adapter member 700 in the longitudinal direction of the adapter member 700. This makes the second elastic bead 910 more easily elastically deformed.

Further, as shown in fig. 7 and 9, a hollow portion 740 is disposed on a wall of the adapter member 700 in the length direction of the adapter member 700, the wall being close to the second elastic protrusion 910, so as to form a bridge-shaped structure extending in the circumferential direction, and the second elastic protrusion 910 is located on the bridge-shaped structure extending in the circumferential direction. This can further improve the degree of elastic deformation of the portion of the wall of the adaptor member 700 where the second elastic protrusion 910 is provided, thereby further improving the operability of the user in adjusting the rotational position of the rod-shaped body 650.

In some alternative embodiments, the rotational positioning assembly 900 may be formed directly between the rod 650 and the cartridge 560. For example, the second elastic locking protrusion 910 of the rotational positioning component 900 may be disposed on the outer wall surface of the rod-shaped body 650, and the corresponding plurality of second locking grooves 912 may be disposed on the inner wall surface of the cylindrical body 560; alternatively, the second elastic locking protrusion 910 of the rotational positioning member 900 may be disposed on the inner wall surface of the cylindrical body 560, and the corresponding plurality of second locking grooves 912 may be disposed on the outer wall surface of the rod-shaped body 650.

When the user wears the smart glasses 100, as shown in fig. 12, when an external rotational force greater than a predetermined rotational force is applied to the rod 650 in a direction rotating about the axis O, the second elastic latching protrusion 910 is elastically deformed, slides out of the currently engaged second latching groove 912, rotates into another second latching groove 912, and is engaged with another second latching groove 912, and when the external rotational force is smaller than the predetermined rotational force or is removed, the temple 300 can be reliably positioned at the adjusted rotational position by the engagement force of the second elastic latching protrusion 910 and the second latching groove 912.

In this embodiment, the second card slot 912 has four. It should be noted that the number of the second card slots 912 in the present application is not limited to four, and may be set appropriately according to actual requirements, and the protection scope of the present application is not limited herein.

As shown in fig. 11-12, the rod 650 is capable of multiple levels of rotational position adjustment and positioning relative to the cartridge 560 in a predetermined rotational region 950. Here, the rotation positions of the predetermined rotation region 950 at the head and tail ends in the rotation direction are defined as a head rotation position 952 and a tail rotation position 954, respectively. In the present embodiment, the leading rotational position 952 is a rotational position at a rotational angle of 0 °, and the trailing rotational position 954 is a rotational position at a rotational angle of 90 °. When the rod-shaped body 650 is rotated to a plurality of rotational positions of the predetermined rotational region 950 with respect to the cylinder 560, the relative rotational movement between the rod-shaped body 650 and the cylinder 560 about the axis O can be restricted, so that multi-stage adjustment of the rotational position between the rod-shaped body 650 and the cylinder 560 in the rotational direction about the axis O can be achieved, and relatively reliable positioning between the rod-shaped body 650 and the cylinder 560 at the adjusted rotational position can be ensured, improving flexibility, operability, and reliability of adjustment.

As will be understood by referring to fig. 3 to 5 and fig. 11 to 12, when the rod-shaped body 650 rotates around the axis O to the head end rotation position 952 with respect to the cylinder-shaped body 560, that is, the rod-shaped body 650 is located at the rotation position of 0 ° with respect to the cylinder-shaped body 560, at this time, the second elastic locking protrusion 910 is engaged with the second locking groove 912 located at the head end, at this time, the clamping force of the rear leg part 600 with the head of the user is minimum, and the other end 620 of the rod-shaped body 650 is located below one end 610 of the rod-shaped body 650 in the height direction 970 of the smart glasses. That is, the rear leg portion 600 may only be supported and clamped to the ears of the user's head when the rod 650 is rotated about axis O to the head end rotational position 952 relative to the cartridge 560. The rotation position is a rotation position of a user in a normal use state when the user wears the smart glasses 100, and at the rotation position, the clamping force of the smart glasses is relatively small, the comfort is high, and the smart glasses are generally suitable for common scenes.

Referring to fig. 11 to 15, when the rod 650 rotates around the axis O to the rear end rotation position 954 with respect to the cylinder 560, the rod 650 is located at a rotation position of 90 ° with respect to the cylinder 560, and at this time, the second elastic protrusion 910 is engaged with the second engaging groove 912 located at the rear end, and at this time, the holding force of the rear leg part 600 with the head of the user is the largest, and the other end 620 of the rear leg part 600 is located inside the front leg part 500 in the width direction 960 of the smart glasses. That is, when the rod 650 is rotated about the axis O to the caudal rotational position 954 with respect to the cylinder 560, the hind leg portion 600 is supported and clamped to the brain or back of the brain of the user's head. When the rod 650 is located at the tail end rotation position 954, the holding force and the wrapability of the smart glasses 100 are the greatest, and the smart glasses are generally suitable for a motion scene with a large motion amplitude. Therefore, the rotation angle within 0-90 degrees can be adjusted, the clamping force and the wrapping property can be adjusted, a user can adjust the intelligent glasses 100 to a desired position when wearing the glasses according to requirements, and the operation is more flexible and reliable.

It will be understood by those skilled in the art that the rotation angle range of the predetermined rotation region 950 can be adaptively set according to actual requirements, and is not limited to the rotation angle adjustment within the range of 0 ° to 90 °, and may also be a rotation angle adjustment within the range of more than 90 °, which does not limit the protection scope of the present application.

The pair of temples 300 are shaped such that their shape substantially conforms to the shape of the user's head, particularly substantially conforms or conforms to the brain or back of the user's head, after being assembled to the frame 200 or smart eyewear 100. The posterior leg portion 600 of the temple 300 may be formed with an arc that substantially conforms to the shape of the posterior lateral region of the user's head (i.e., the arc formed at the curved segment 640 conforms to the shape of the posterior lateral portion of the user's head) so that the posterior leg portion 600 may be more conformable to the posterior lateral region of the head when adjusted to the proper rotational position, facilitating secure wear. The rear leg portion 600 of the temple 400 may be constructed of a material that is flexible, particularly moderately elastically flexible. Through such design for the intelligent glasses 100 of this application can furthest increase the area of contact with user's head when adjusting to suitable rotational position after wearing to reduce the oppression sense to the head, increase the comfort level.

Referring to fig. 14, the two temples 300, after being assembled to the frame 200 or the smart glasses 100, and rotating the rear leg part 600 to a rotational position rotated by 90 ° with respect to the front leg part 500, may assume an open structure substantially conforming to the shape of the brain or the back of the brain of the user's head, i.e., a half-wrapped structure. With this arrangement and configuration, wearing is convenient.

Referring to fig. 16-21, fig. 16-21 show schematic structures of another smart glasses 100 provided by an embodiment of the present application. In which fig. 18 to 21 highlight the schematic structure of the region where the rear leg part 600 of the temple 400 is connected to the front leg part 500.

As shown in fig. 16 to 21, the smart glasses 100 of the present embodiment have substantially the same structure as the smart glasses 100 of the embodiment shown in fig. 1 to 15, and include a frame 200 and a lens 240, wherein the frame 200 includes a frame body 220 and two legs 300 respectively disposed at two sides of the frame body 220. The lenses 240 are secured to the frame body 220. Each temple 300 is constructed in a segmented structure, one end 510 of the front leg part 500 is connected to the frame main body 220, the other end 520 of the front leg part 500 is connected to one end 610 of the rear leg part 600, and a structure enabling a moving position adjustment and a rotational position adjustment is provided between the rear leg part 600 and the front leg part 500. The difference is that the temple 300 has a different specific structure for performing the adjustment of the moving position and the adjustment of the rotational position, that is, the temple posture adjustment apparatus 400 has a different structure.

It will be understood by those skilled in the art that one temple 300 of the smart eyewear 100 may employ the temple 300 provided in any of the following embodiments and possible embodiments shown in fig. 19-21, and the other temple 300 may employ the temple 300 provided in any of the above embodiments and possible embodiments shown in fig. 3-15; alternatively, the structure of each of the two temples 300 of the smart glasses 100 may also adopt the temples 300 provided in any one of the following embodiments and possible embodiments shown in fig. 19-21; alternatively, one of the two temples 300 may be the frame 200 or the smart glasses 100 according to the embodiment of the present application shown in fig. 19 to 21.

The structure of another embodiment of one temple 300 of the smart glasses 100 will be mainly described with reference to fig. 16 to 21.

As shown in fig. 16 to 21, the temple-posture adjusting means 400 includes a cylindrical body 560, a rod body 650, and a damping member 930. The cylinder 560 is provided with a housing chamber 530 extending in the direction of the axis O. The rod-shaped body 650 extends into the accommodation chamber 530 in the direction of the axis O, and one end of the rod-shaped body 650 is a free end. The cylindrical body 560 is formed for the rear section where the other end 520 of the front leg part 500 is located, and the rod-shaped body 650 is formed extending from the one end 610 of the rear leg part 600 in the direction of the axis toward the direction away from the rear leg part 600. That is, the cartridge 560 is fixed with respect to the front leg part 500, and the rod 650 is fixed with respect to the rear leg part 600. In this embodiment, the rod-shaped body 650 has a diameter smaller than that of the rear leg portion 600.

As shown in fig. 19, the damping member 930 extends in the direction of the axis O and is located in the accommodation chamber 530. The outer wall surface of the damper member 930 is fixed to the inner wall surface of the cylindrical body 560. And the damping member 930 is fitted around the outer wall surface of the rod 650 and is in interference fit with the rod 650.

As shown in fig. 19, when the rod-shaped body 650 receives an external moving force in the direction along the axis O greater than the interaction force between the damping member 930 and the rod-shaped body 650 in the direction along the axis O (i.e., the predetermined moving force mentioned in the above-mentioned embodiment), the rod-shaped body 650 can move in the direction along the axis O with respect to the damping member 930 and the cylinder-shaped body 560, so that the adjustment of the moving position of the rear leg portion 600 of the temple 300 with respect to the front leg portion 500 in the direction along the axis O can be achieved. When the external moving force received is cancelled or smaller than the interaction force between the damping member 930 and the rod-shaped body 650 in the direction of the axis O, the rod-shaped body 650 can be fixed in the direction along the axis O with respect to the damping member 930 and the cylinder-shaped body 560, so that the temple 300 is fixed in the adjusted moving position, ensuring reliability of use.

As shown in fig. 19 to 21, when the rod-shaped body 650 is subjected to an external rotational force in the direction of rotation about the axis O which is greater than the interaction force between the damping member 930 and the rod-shaped body 650 in the direction of rotation about the axis O (i.e., the predetermined rotational force mentioned in the above-mentioned embodiment), the rod-shaped body 650 can be rotated in the direction of rotation about the axis O with respect to the damping member 930 and the cylinder-shaped body 560, so that the adjustment of the rotational position of the rear leg portion 600 of the temple 300 with respect to the front leg portion 500 in the direction of rotation about the axis O can be achieved. When the external moving force received is cancelled or smaller than the interaction force between the damping member 930 and the rod-shaped body 650 in the direction of rotation about the axis O, the rod-shaped body 650 can be fixed in the direction of rotation about the axis O with respect to the damping member 930 and the cylinder-shaped body 560, so that the temple 300 is fixed in the adjusted rotational position, ensuring reliability of use.

Further, as shown in fig. 19, the stopper 920 may include a stopper boss 926, and the stopper boss 926 is protruded from an inner wall surface of the cylindrical body 560 forming the receiving chamber 530. The end of the rod 650 remote from the rear leg portion 600 is provided with a flange 928. When the rod-shaped body 650 moves rearward in the direction of the axis O relative to the cylindrical body 560 to a position where the flange 928 abuts the limit boss 926, the movement of the rod-shaped body 650 rearward in the direction of the axis O relative to the damping member 930 and the cylindrical body 560 is limited. The rod 650 can be prevented from slipping out of the cylinder 560, and the rear leg part 600 can be prevented from slipping out of the front leg part 500 in the case of excessive force applied by the user at the time of operation. Thus, the reliability and safety of use are improved.

In the present embodiment, the damping member 930 is made of silicon rubber. The damping member 930 may be made of other materials capable of producing a damping effect, and the scope of the present invention is not limited thereto.
