Description

Technical Field

[0001] The present application relates to the field of head-mounted devices, and more specifically, to smart glasses. Background Art

[0002] In recent years, smart glasses have gradually entered people's lives. On the one hand, the design of smart glasses needs to meet basic storage and wearing needs, such as designing the temples to be rotatable relative to the frame to achieve folding of smart glasses when not in use, thereby reducing the size of smart glasses and facilitating the storage of smart glasses when not in use. In addition, energy storage components such as torsion springs are designed between the frame and the temples so that the temples always have a tendency to turn to the folded state when open, so that users with different face shapes can keep the temples clamped when wearing smart glasses, avoid smart glasses from slipping off, and improve the versatility of smart glasses; on the other hand, it needs to meet multi-functional use needs, such as setting microphone modules, imaging systems, projection systems, etc. for voice recognition, gesture recognition, image processing, and then realizing real-time navigation, conference communication, audio and video playback and other functions.

[0003] With the continuous integration of the functions of smart glasses, the structure of smart glasses is becoming more and more complex, resulting in the smart glasses becoming larger and heavier, and the wearing comfort of smart glasses is poor. Therefore, the lightweight design of smart glasses is still a difficulty in the industry.

[0004] During the use of smart glasses, the temples will be folded and opened many times, and the temples and the frame, especially the parts related to relative rotation, are prone to wear due to friction, resulting in looseness between the temples and the frame of the smart glasses, and even causing certain functional failures. For example, the energy storage components are partially detached from the constraints, resulting in the failure of the clamping function of the temples. In addition, due to the limitation of the accommodation space, the electrical connecting wires inside the temples are also easily squeezed and worn during the rotation of the temples, resulting in the failure of the electrical connecting wires.

DETAILED DESCRIPTION

[0058] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0059] like Figures 1 to 24 As shown, smart glasses 100 according to an embodiment of the present application are illustrated.

[0060] like Figures 1 to 4As shown, the smart glasses 100 include a frame 10, two temples 20, an energy storage component 30, a waveguide 50, a circuit board 80 and an elastic element 41. The frame 10 is provided with a temple connection portion 12, the temple connection portion 12 is hollow inside, and the temple connection portion 12 is provided with a first contact surface 1201. The temple 20 is rotatably connected to the temple connection portion 12 of the frame 10. The temple 20 can switch between an open state and a folded state as it rotates. In other words, the temple 20 has an open state and a folded state as it rotates. The temple 20 is hollow inside, and the temple 20 and / or the temple connection portion 12 form a first channel 101. The temple 20 is provided with a second contact surface 201. The second contact surface 201 of the temple 20 is opposite to the first contact surface 1201 in the extension direction of the rotation axis L of the temple 20. The waveguide 50 is mounted on the frame 10. The circuit board 80 is accommodated in the temple 20 , and the circuit board 80 is connected with an electrical connection line 70 . The electrical connection line 70 passes through the first channel 101 and enters the interior of the temple connection part 12 .

[0061] The elastic element 41 is located outside the first channel 101, and is constrained between the temple 20 and the temple connecting portion 12, and is in a pre-compression state, so that the second contact surface 201 always has a tendency to approach the first contact surface 1201 in the extension direction of the rotation axis L of the temple. The energy storage component 30 is arranged between the temple connecting portion 12 and the temple 20, and is used to provide the temple 20 in the open state with a force to clamp the temple 20.

[0062] The electrical connection line 70 is used to connect the circuit board 80 and the electrical components arranged on the frame 10, that is, the two ends of the electrical connection line 70 are electrically connected to the circuit board 80 and the electrical components arranged on the frame 10, respectively, wherein the electrical components of the frame 10 can be an antenna, an imaging module (for example, a camera module and / or a projection module), etc.; or, the electrical connection line 70 is a part of the electrical components, that is, the electrical connection line 70 is integrally arranged with the circuit board 80.

[0063] It is worth mentioning that in the present application, the electrical connection line 70 is arranged in its dedicated space, that is, in the first channel 101, and the elastic element 41 is arranged outside the first channel 101, which can reduce the friction between the electrical connection line 70 and the elastic element 41 when the temple 20 rotates relative to the frame 10, thereby making the electrical connection line 70 less likely to be worn, further avoiding affecting the layout and connection stability of the electrical connection line 70, and avoiding failure of the smart glasses 100 due to damage to the electrical connection line 70.

[0064] It is also worth mentioning that the elastic element 41 is constrained between the frame 10 and the temple 20, forming a pre-compression structure between the frame 10 and the temple 20, so that the second contact surface 201 always has a tendency to approach the first contact surface 1201 in the extension direction of the rotation axis L of the temple 20, so that the first contact surface 1201 can maintain a state of conflict with the second contact surface 201. In this way, after the smart glasses are used for a long time, the temples 20 rotate relative to the frame 10, so that the temples 20 and the frame 10 are prone to wear, and then the temples 20 become loose relative to the frame 10; and, the temples 20 and the frame 10 inevitably have processing tolerances during the processing, which causes the temples 20 and the frame 10 to become loose after assembly. Therefore, the setting of the elastic element 41 can not only compensate for the size differences of different parts caused by the processing tolerances during the assembly stage of the smart glasses, thereby adapting to the assembly dimensions of different products, so that the smart glasses can be better assembled and the looseness caused by the processing tolerances of the temples 20 and the frame 10 can be avoided, but also the gap margin caused by wear between the temples 20 and the frame 10 can be compensated during the use of the smart glasses, and the temples 20 and the temple connecting parts 12 can be continuously tightly matched to ensure that the smart glasses can still maintain good assembly during the use stage.

[0065] Specifically, the eyeglass frame 10 includes an eyeglass frame body 11 and two temple connecting parts 12. The eyeglass frame body 11 has a first side portion 110 and a second side portion 120 opposite to each other in the lateral direction (i.e., in the left-right direction). The two temple connecting parts 12 extend rearward from the first side portion 110 and the second side portion 120 of the eyeglass frame body 11, respectively. The temple connecting part 12 and the temple 20 are rotatably connected through a vertically arranged rotating shaft 90, that is, the extending direction of the rotating axis L of the temple 20 is vertical.

[0066] The temple connecting portion 12 has a hollow cavity in the frame, and the hollow cavity in the frame forms a hollow structure inside the temple connecting portion 12. The temple connecting portion 12 includes an upper portion 121 and a lower portion 122 spaced apart in the extending direction of the rotation axis L of the temple 20, that is, vertically, wherein a gap 1202 is provided between the upper portion 121 and the lower portion 122 of the temple connecting portion 12.

[0067] The temple 20 has a temple hollow cavity 202, and the temple hollow cavity 202 forms a hollow structure inside the temple 20. One end of the temple 20 is connected to the temple connecting portion 12, and the other end is used to contact the ear of the user; one end of the temple 20 has a top 21 and a bottom 22, and the first channel 101 is located between the top 21 and the bottom 22, and the first channel 101 is connected to the temple hollow cavity 202.

[0068] In one embodiment of the present application, the temple 20 extends into the gap 1202 between the upper portion 121 and the lower portion 122 of the temple connecting portion 12, so that the upper portion 121 of the temple connecting portion 12 is located above the top 21 of the temple 20, and the lower portion 122 of the temple connecting portion 12 is located below the bottom 22, and the rotating shaft 90 passes through the upper portion 121 of the temple connecting portion 12, the top 21 of the temple 20, the lower portion 122 of the temple connecting portion 12 and the bottom 22 of the temple 20, so as to realize the rotational connection between the temple connecting portion 12 and the temple 20, and to connect the first channel 101 with the hollow cavity in the frame, so that the first channel 101 connects the hollow cavity 202 of the temple and the hollow cavity in the frame, thereby allowing the electrical connection line 70 to pass through the first channel 101 and enter the interior of the temple connecting portion 12.

[0069] It should be understood that in a modified embodiment, it can be designed that the first channel is provided inside the temple connection part, the temple connection part extends into the temple, so that the top of the temple is located above the upper part of the temple connection part, and the bottom of the temple is located below the lower part of the temple connection part. It can also be that the first channel is formed by the temple connection part and the temple, such as the top of the temple is located above the upper part of the temple connection part, and the lower part of the temple connection part is located below the bottom of the temple, so that the temple connection part and the temple are in a staggered plug-in state.

[0070] The specific installation method of the rotating shaft 90 is not limited by the present application. In an example of the present application, the temple 20 extends into the gap 1202 of the temple connecting portion 12; the temple 20 has a through hole 203 that penetrates the temple 20 in the extension direction of the rotation axis L. The temple connecting portion 12 has an upper shaft hole 1203 formed in the upper portion 121 of the temple connecting portion 12 and a lower shaft hole 1204 formed in the lower portion 122 of the temple connecting portion 12. Fig.10 and Fig.11The rotating shaft 90 passes through the through hole 203 of the temple 20, and the upper end of the rotating shaft 90 extends from above the through hole 203 of the temple 20 and extends into the upper shaft hole 1203, and the lower end of the rotating shaft 90 extends from below the through hole 203 of the temple 20 and extends into the lower shaft hole 1204.

[0071] It should be understood that in other examples of the present application, the rotating shaft 90 can be set in other ways; for example, the temple extends into the temple connecting part; one rotating shaft is set between the upper part of the temple connecting part and the top of the temple, and one rotating shaft is set between the lower part of the temple connecting part and the bottom of the temple; any one of the rotating shafts does not pass through the temple; for another example, the temple connecting part extends into the temple; the temple connecting part has a through hole that passes through the temple connecting part in the extension direction of the rotation axis L of the temple; the temple has an upper mounting hole formed on its top hole and a lower mounting hole formed at the bottom thereof; the rotating shaft passes through the through hole of the temple connecting portion, and the upper end of the rotating shaft extends from above the through hole of the temple connecting portion and extends into the upper mounting hole; the lower end of the rotating shaft extends from below the through hole of the temple connecting portion and extends into the lower mounting hole; for another example, the temple connecting portion extends into the temple; one rotating shaft is arranged between the upper part of the temple connecting portion and the top of the temple, and one rotating shaft is arranged between the lower part of the temple connecting portion and the bottom of the temple; any one of the rotating shafts does not pass through the temple connecting portion.

[0072] The elastic element 41 includes a first portion 411 and a second portion 412, wherein the first portion 411 is provided at one of the temple 20 and the temple connecting portion 12, and the other of the temple 20 and the temple connecting portion 12 is provided with a third contact surface 102. The second portion 412 of the elastic element 41 is located between the third contact surface 102 and one of the temple 20 and the temple connecting portion 12.

[0073] In one embodiment of the present application, the temple 20 is further provided with a damping sheet 43, the bottom wall of the temple 20 is located at the bottom 22, and the damping sheet 43 is located at the bottom wall of the temple 20. Figure 6As shown. Specifically, the bottom wall of the temple 20 has a damping mounting groove 2201; the damping sheet 43 is installed in the damping mounting groove 2201 of the bottom wall. The damping sheet 43 can be implemented as a metal sheet. It should be understood that the wear resistance of metal sheets is generally better than that of plastics, which can reduce loosening caused by wear. Preferably, the outer contour of the metal sheet is arc-shaped, and the arc surrounds the central axis of the rotating shaft 90, which occupies little space on the temple 20 and can thin the temple 20, thereby facilitating the lightweight of the smart glasses 100.

[0074] In this embodiment, the temple 20 extends into the gap 1202 between the upper portion 121 and the lower portion 122 of the temple connecting portion 12; the elastic element 41 is located outside the first channel 101 and below the temple 20. The first portion 411 of the elastic element 41 is disposed at the temple connecting portion 12, more specifically, the first portion 411 of the elastic element 41 is disposed inside the lower portion 122 of the temple connecting portion 12; the lower surface of the damping sheet 43 forms the third contact surface 102. In the vertical direction, the second contact surface 201 and the elastic element 41 are located on both sides of the first channel 101. The top wall of the temple 20 is located at the top portion 21, and the top wall of the temple 20 forms the second contact surface 201, and the lower surface of the upper portion 121 of the temple connecting portion 12 forms the first contact surface 1201.

[0075] The elastic element 41 deviates from the rotating shaft 90 and is adjacent to the rotating shaft 90. It should be understood that the closer the elastic element 41 is to the rotating shaft 90, the smaller the torque generated by the elastic element 41, the less likely the temple 20 is to be skewed, and the contact area between the first contact surface 1201 and the second contact surface 201 can be made larger, thereby making the assembly quality of the smart glasses 100 higher. In an example of the present application, in the radial direction of the rotating shaft 90, the radial distance between the torsion spring 31 and the rotating shaft 90 does not exceed 3 times the diameter of the rotating shaft 90.

[0076] Correspondingly, the upper surface of the lower part 122 of the temple connecting part 12 and the lower surface of the damping plate 43 are opposite to each other in the extension direction of the rotation axis L of the temple 20; the elastic element 41 is constrained between the lower part 122 of the temple connecting part 12 and the lower surface of the damping plate 43, and is in a pre-stressed state, so that the elastic element 41 provides an upward supporting force for the temple 20, prompting the second contact surface 201 of the temple 20 and the first contact surface 1201 of the temple connecting part 12 to maintain a tendency to approach each other, and using its elasticity to adaptively compensate for the wear of the temple 20 and / or the temple connecting part 12 in the extension direction of the rotation axis L of the temple 20, or the tolerance of the temple 20 and / or the temple connecting part 12 in the extension direction of the rotation axis L of the temple 20, thereby preventing the temple 20 from loosening relative to the temple connecting part 12 of the frame 10. A part of the restoring force of the elastic element 41 can also offset the gravity of the temple 20, reduce the pressure of the second contact surface 201 pressing against the first contact surface 1201, avoid the large friction between the temple 20 and the temple connecting part 12 when the temple 20 rotates, and make the friction between the temple 20 and the temple connecting part 12 appropriate when the temple 20 rotates, so as to ensure the comfortable feel of the temple 20 when it rotates.

[0077] It should be understood that the damping sheet 43 can also be set at other positions. In a modified embodiment of the present application, the damping sheet is located at the top of the temple. In this embodiment, the temple extends into the temple connecting portion; the first portion is set at the upper part of the temple connecting portion; the upper surface of the damping sheet forms the third contact surface. The lower surface of the bottom of the temple forms the second contact surface, and the upper surface of the lower part of the temple connecting portion forms the first contact surface.

[0078] In another variant embodiment of the present application, the damping sheet is located at the bottom of the temple. In this embodiment, the temple connecting portion extends into the temple; the first portion is arranged at the lower part of the temple connecting portion; and the upper surface of the damping sheet forms the third contact surface. The lower surface of the top of the temple forms the second contact surface, and the upper surface of the upper part of the temple connecting portion forms the first contact surface.

[0079] In another variant embodiment of the present application, the damping sheet is located at the top of the temple. In this embodiment, the temple connecting portion extends into the temple; the first portion is arranged at the upper portion of the temple connecting portion; and the lower surface of the damping sheet forms the third contact surface. The upper surface of the bottom of the temple forms the second contact surface, and the lower surface of the lower portion of the temple connecting portion forms the first contact surface.

[0080] In a modified embodiment of the present application, the damping sheet is located at the lower part of the temple connection part. In this embodiment, the temple extends into the temple connection part; the first part is arranged at the bottom of the temple; the upper surface of the damping sheet forms the third contact surface. The upper surface of the top of the temple forms the second contact surface, and the lower surface of the upper part of the temple connection part forms the first contact surface.

[0081] In another variant embodiment of the present application, the damping sheet is located at the upper part of the temple connection part. In this embodiment, the temple extends into the temple connection part; the first part is arranged at the top of the temple; the lower surface of the damping sheet forms the third contact surface. The lower surface of the bottom of the temple forms the second contact surface, and the upper surface of the lower part of the temple connection part forms the first contact surface.

[0082] In another variant embodiment of the present application, the damping sheet is located at the lower part of the temple connection portion. In this embodiment, the temple connection portion extends into the temple; the first portion is arranged at the bottom of the temple; the lower surface of the damping sheet forms the third contact surface. The lower surface of the top of the temple forms the second contact surface, and the upper surface of the upper part of the temple connection portion forms the first contact surface.

[0083] In another variant embodiment of the present application, the damping sheet is located at the upper part of the temple connection portion. In this embodiment, the temple connection portion extends into the temple; the first portion is arranged at the top of the temple; the upper surface of the damping sheet forms the third contact surface. The upper surface of the bottom of the temple forms the second contact surface, and the lower surface of the lower part of the temple connection portion forms the first contact surface.

[0084] Preferably, the elastic element 41 is constrained to the temple connection portion 12. Specifically, the first portion 411 of the elastic element 41 is provided at the temple connection portion 12. More specifically, when the temple 20 and the frame 10 rotate relative to each other, the temple 20 is mainly rotated, and the temple connection portion 12 of the frame 10 remains substantially stationary. The first portion 411 is provided on the temple connection portion 12 that remains substantially stationary, which can reduce the load on the temple 20, so that the driving force required to rotate the temple 20 is smaller, and the rotation is easier.

[0085] It is worth mentioning that, in one embodiment of the present application, the smart glasses 100 further include a sphere 42. The sphere 42 is disposed at the second portion 412 of the elastic element 41. The sphere 42 is in conflict with the third contact surface 102. The presence of the elastic element 41 can increase the friction force on the temple 20 during the rotation process. Benefiting from the curved surface of the sphere 42, the sphere 42 can reduce the friction force on the temple 20 during the rotation process, so that the user feels smoother when rotating the temple 20.

[0086] The rotation axis L of the temple 20 is arranged vertically. Preferably, the elastic element 41 is located below the sphere 42, so that a part of the restoring force of the elastic element 41 can offset the gravity of the temple 20, avoiding a large friction force when the temple 20 rotates, so that the temple 20 has a suitable friction force when rotating, and ensuring a comfortable hand feeling when the temple 20 rotates.

[0087] In one embodiment of the present application, the smart glasses 100 further include a support carrier 44, and the elastic element 41 is mounted on the support carrier 44. In an example of the present application, the support carrier 44 is mounted on the temple connecting portion 12, and the elastic element 41 is arranged on the temple connecting portion 12 by being mounted on the support carrier 44. The specific structure and mounting method of the support carrier 44, and the matching method with the elastic element 41 are not limited by the present application. In this example, the temple connecting portion 12 has a support carrier mounting hole 4401, and the support carrier 44 is mounted on the support carrier mounting hole 4401. The elastic element 41 can be implemented as a spring, and the support carrier 44 can be implemented as a screw; the elastic element 41 implemented as a spring can be sleeved on the support carrier 44.

[0088] It is also worth mentioning that in the embodiment of the present application, the elastic element 41 can not only be used as a pre-compression structure to prevent the temple 20 from loosening relative to the frame 10, but can also cooperate with the sphere 42 and the damping plate 43 to form a positioning assembly 40 to position the temple 20, so that the user can experience the pause and position feeling when the temple 20 is rotated to a specific position during the process of opening or folding the smart glasses 100. That is, the pre-compression structure and the positioning assembly 40 share the elastic element 41, which can reduce the parts of the smart glasses 100, thereby reducing the assembly process, and can also make the overall structure of the smart glasses 100 more concise and lighter, which can improve the user's wearing experience of the smart glasses 100 to a certain extent.

[0089] Accordingly, the positioning component 40 is located outside the first channel 101, which can reduce the friction between the electrical connection line 70 and the positioning component 40 when the temple 20 rotates relative to the frame 10, thereby avoiding damage to the electrical connection line 70, further avoiding affecting the layout and connection stability of the electrical connection line 70, and avoiding failure of the smart glasses 100 due to damage to the electrical connection line 70.

[0090] Specifically, Fig. 9 As shown, the third contact surface 102 is provided with a first groove 431 and a second groove 432 at intervals along the circumferential direction of the rotation axis L of the temple 20. In one embodiment of the present application, the third contact surface 102 is formed on the temple 20, and correspondingly, the second groove 432 and the first groove 431 are provided on the temple 20. In one example of the present application, the second groove 432 and the first groove 431 are directly provided on the bottom wall of the temple 20. In another example of the present application, the second groove 432 and the first groove 431 are provided on the damping sheet 43 of the temple 20.

[0091] When the temple 20 is in a folded state, the ball 42 is inserted into the second groove 432 ; when the temple 20 is in an opened state, the ball 42 is inserted into the first groove 431 .

[0092] During the process of switching the temple 20 between the folded state and the opened state, the ball 42 is located between the second groove 432 and the first groove 431. In order to make the ball 42 transition between the second groove 432 and the first groove 431 more smoothly, the present application makes a specific design for the shapes of the second groove 432 and the first groove 431.

[0093] Specifically, the side surfaces of the second groove 432 and the first groove 431 are inclined relative to the vertical plane. More specifically, along the circumference of the rotation axis L of the temple 20, the first groove 431 has a first side surface 4311 and a second side surface 4312 opposite to each other, the first side surface 4311 is adjacent to the second groove 432, and the second side surface 4312 is away from the second groove 432. Along the circumference of the rotation axis L of the temple 20, the second groove 432 has a third side surface 4321 and a fourth side surface 4322 opposite to each other, the third side surface 4321 is adjacent to the first groove 431, and the fourth side surface 4322 is away from the first groove 431.

[0094] From the mouth of the first groove 431 to the bottom of the first groove 431, the second side surface 4312 gradually approaches the first groove 431. When the temple 20 is in the open state, when the temple 20 is further rotated to open a larger angle, the ball 42 contacts the second side surface 4312 under the action of the elastic element 41, and the restoring force of the elastic element 41 makes the ball 42 tend to move toward the bottom of the first groove 431, thereby reversely pushing the temple 20 to rotate in the direction of switching to the folded state, thereby promoting the temple 20 to maintain a clamped state with the user's head.

[0095] From the mouth of the first groove 431 to the bottom of the first groove 431, the first side surface 4311 gradually moves away from the second groove 432; and / or, from the mouth of the second groove 432 to the bottom of the second groove 432, the third side surface 4321 gradually moves away from the first groove 431. When the temple 20 is switched between the open state and the folded state, the third side surface 4321 and the first side surface 4311 can guide the ball 42 to escape from the first groove 431 or the second groove 432, so as to facilitate the state switching of the temple 20.

[0096] In the embodiment of the present application, the energy storage assembly 30 is disposed between the temple connecting portion 12 and the temple 20 .

[0097] It is worth mentioning that, optionally, the energy storage component 30 is arranged outside the first channel 101, which can reduce the friction between the electrical connection line 70 and the energy storage component 30 when the temple 20 rotates relative to the frame 10, thereby avoiding damage to the electrical connection line 70, and further avoiding affecting the layout and connection stability of the electrical connection line 70, and avoiding failure of the smart glasses 100 due to damage to the electrical connection line 70.

[0098] It is also worth mentioning that, benefiting from the fact that the first contact surface 1201 and the second contact surface 201 always have a tendency to approach each other in the extension direction of the rotation axis L of the temple 20, so that the first contact surface 1201 and the second contact surface 201 always maintain a contact state, the clamping effect of the energy storage component 30 installed between the frame 10 and the temple 20 and the positioning effect of the positioning component 40 installed between the frame 10 and the temple 20 are more stable.

[0099] The energy storage assembly 30 includes a torsion spring 31 and a resisting member 32. Accordingly, the torsion spring 31 and the resisting member 32 are arranged between the temple connecting portion 12 and the temple 20. Optionally, the torsion spring 31 and the resisting member 32 are arranged outside the first channel 101. The energy storage assembly 30 is configured such that when the temple 20 is in the open state, the torsion spring 31 is in the energy storage state, and the temple 20 in the open state always has a rotation tendency to transform to the folded state.

[0100] The torsion spring 31 has a fixed end 311, a movable end 312, and a spiral portion 313 extending between the fixed end 311 and the movable end 312. In this example, the torsion spring 31 is sleeved on the rotating shaft 90.

[0101] Preferably, if Figures 2 to 6 As shown, in the extension direction of the rotation axis L of the temple 20, that is, vertically, the torsion spring 31 and the elastic element 41 are respectively located on both sides of the first channel 101 to avoid crowding and mutual influence of the energy storage component 30 and the positioning component 40, so that the space allocation in the smart glasses 100 is reasonable and the utilization rate is high. The torsion spring 31 and the elastic element 41 are arranged vertically, which can reduce the thickness of the temple 20, making the smart glasses 100 smaller in size after folding, and can also prevent the temple 20 from being too tight in the open state to affect the wearing comfort.

[0102] Correspondingly, when the elastic element 41 is disposed on the lower side of the first channel 101 , the torsion spring 31 may be disposed on the upper side of the first channel 101 ; when the elastic element 41 is disposed on the upper side of the first channel 101 , the torsion spring 31 may be disposed on the lower side of the first channel 101 .

[0103] The fixed end 311 is fixed to one of the temple connecting portion 12 and the temple 20; one of the temple connecting portion 12 and the temple 20 is provided with a first receiving groove 103, a second channel 104 and a second receiving groove 106, wherein the depth of the second receiving groove 106 is deeper than the first receiving groove 103, and the second receiving groove 106 is communicated with the first receiving groove 103. The first receiving groove 103 is provided with a fourth contact surface 105, and the first receiving groove 103 is communicated with the second channel 104 on the side where the fourth contact surface 105 is located. The fixed end 311 and the spiral portion 313 of the torsion spring 31 are accommodated in the second receiving groove 106, and the movable end 312 of the torsion spring 31 is limited in the first receiving groove 103.

[0104] In one embodiment of the present application, the torsion spring 31 is installed on the temple 20, so that the torsion spring 31 directly acts on the temple 20 to drive the temple 20 to move closer to each other to clamp the user's head. Figure 7 and Figure 8 As shown, the first accommodating groove 103, the second accommodating groove 106 and the second channel 104 are arranged on the temple 20. The fixed end 311 is fixed to the temple 20, and the fourth contact surface 105 contacts the movable end 312 of the torsion spring 31 when the temple 20 is in a folded state.

[0105] Further, in an embodiment of the present application, the torsion spring 31 is installed above the first channel 101. In this embodiment, the temple 20 extends into the temple connecting portion 12; the torsion spring 31 is installed at the top 21 of the temple 20. Accordingly, the first receiving groove 103, the second channel 104 and the second receiving groove 106 are formed at the top 21 of the temple 20, and the fixed end 311 of the torsion spring 31 is fixed to the second receiving groove 106.

[0106] It should be understood that the torsion spring 31 can also be arranged at other positions. In a modified embodiment of the present application, the temple connecting portion extends into the temple; the torsion spring is installed on the top of the temple. Accordingly, the first receiving groove, the second channel and the second receiving groove are formed on the top wall of the temple, and the fixed end of the torsion spring is fixed to the second receiving groove.

[0107] The resisting member 32 is located on the rotation path of the movable end 312 .

[0108] like Figures 12 to 15 As shown, when the angle between the temple 20 and the frame body 11 is almost 0°, the temple 20 is in a folded state, and the ball 42 is accommodated in the second groove 432, so that the temple 20 is positioned in the folded state. The movable end 312 of the torsion spring 31 abuts against the fourth contact surface 105 of the first receiving groove 103, so that the torsion spring 31 is in a first energy storage state (the first energy storage state is achieved by installing the torsion spring 31 in the first receiving groove 103 and the second receiving groove 106), which can provide a small elastic restoring force for the rotation of the temple 20 to maintain a proper operating feel. At this time, the abutment 32 is separated from the movable end 312 of the torsion spring 31.

[0109] When the temple 20 rotates relative to the frame 10, so that the angle between the temple 20 and the frame body 11 changes from 0° to the first preset angle α, the temple 20 changes from the folded state to the opened state, and the ball 42 disengages from the second groove 432 and rotates toward the first groove 431, and abuts against the damping sheet 43 to provide damping during the rotation of the temple 20. At the same time, the abutment 32 slides along the second channel 104, but is still separated from the active end 312 of the torsion spring 31. During this process, the active end 312 of the torsion spring 31 always abuts against the fourth contact surface 105 of the first accommodating groove 103, and is still in the first energy storage state.

[0110] like Figures 16 to 20 As shown, when the temple 20 continues to rotate relative to the frame 10, so that the angle between the temple 20 and the frame body 11 is the first preset angle α, the ball 42 is accommodated in the first groove 431, so that the temple 20 is positioned in the first open state. The abutment 32 slides along the second channel 104 until it contacts the movable end 312 of the torsion spring 31, and the movable end 312 of the torsion spring 31 is in a critical state of contact and separation with the fourth contact surface 105. At this time, the torsion spring 31 is in a state of switching from the first energy storage state to the second energy storage state.

[0111] like Fig. 9 , Figure 21 to Figure 24 As shown, when the temple 20 continues to rotate relative to the frame 10, the angle between the temple 20 and the frame body 11 is the second preset angle β (the second preset angle β> the first preset angle α), although the ball 42 is still accommodated in the first groove 431, the ball 42 abuts against the second side surface 4312, so that the temple 20 is positioned in the second open state. The abutting member 32 pushes the movable end 312 of the torsion spring 31, so that the movable end 312 of the torsion spring 31 is separated from the fourth contact surface 105 of the first accommodating groove 103, so that the torsion spring 31 is in the second energy storage state, which can provide a larger elastic restoring force for the rotation of the temple 20, so that the temple 20 remains in the clamping state. The second energy storage state is a relatively dynamic state, because, as the temple 20 rotates, the elastic restoring force of the torsion spring 31 increases.

[0112] The specific implementation of the first preset angle α and the second preset angle β is not limited by the present application. In an example of the present application, the first preset angle α is equal to 87 degrees, and the second preset angle β is greater than or equal to 98 degrees.

[0113] When the torsion spring 31 is installed on the temple 20, the abutment 32 is installed on the temple connection portion 12 and is disposed on the rotation path of the movable end 312. Specifically, in one embodiment of the present application, the abutment 32 is installed on the upper portion 121 of the temple connection portion 12, extends downward from the upper portion 121, and is inserted into the second channel 104.

[0114] In a specific example of the present application, the upper portion 121 of the temple connecting portion 12 has a resistance member mounting hole 1205 , and the resistance member 32 is mounted in the resistance member mounting hole 1205 .

[0115] In this example, the resistance member 32 passes through the resistance member mounting hole 1205 and extends downward to the rotation path of the movable end 312 .

[0116] Specifically, the resistance member 32 is implemented as a stepped shaft, and the resistance member mounting hole 1205 is implemented as a stepped hole.

[0117] Correspondingly, the resistance member mounting hole 1205 implemented as the step hole has an upper hole portion 12051 and a lower hole portion 12052, and the lower hole portion 12052 extends downward from the upper hole portion 12051; the resistance member 32 implemented as the step has a large diameter portion 321 and a small diameter portion 322, and the small diameter portion 322 extends downward from the large diameter portion 321; the radial dimension of the large diameter portion 321 is larger than the radial dimension of the lower hole portion 12052 of the resistance member mounting hole 1205, and is located above the lower hole portion 12052; the small diameter portion 322 passes through the lower hole portion 12052 and extends to the rotation path of the movable end 312.

[0118] In summary, the smart glasses 100 according to the embodiment of the present application are explained, and the smart glasses 100 are provided with a pre-compression structure between the frame 10 and the temple 20, which can make the frame 10 and the temple 20 always in a tight fit state, and can prevent the temple 20 from loosening relative to the frame 10 to a certain extent.
