Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

In the first embodiment of the smart glasses provided by the present invention, please refer to fig. 1 to 20, which include a frame 2 and temples 6. The glasses legs 6 are provided with control components, the glasses frame 2 is provided with a main control board 21, and the control components are electrically connected to the main control board 21 through electric connectors 5. Specifically, the electrical connector 5 includes an FPC51 and a cable harness 52.

The temples 6 are rotatably coupled to the frame 2 by a hinge assembly so that the temples 6 can be folded in or out with respect to the frame 2. Specifically, in the smart glasses, two temples 6 are connected to the frame 2 through corresponding hinge assemblies, respectively.

The hinge assembly includes an elastic assembly provided in the hinge housing 4. After the temples 6 are turned outwards relative to the spectacle frame 2 and the turning angle is larger than the preset turning angle, the elastic components are elastically deformed so that the temples 6 have the movement tendency of turning inwards, and when the temples 6 are turned outwards relative to the spectacle frame 2 and the turning angle is not larger than the preset angle, the elastic components are in the original state.

Referring to fig. 5 to 7, a line K is a straight line of the frame 2, a line T is a straight line of the temple 6, fig. 6 is a state when the temple 6 is at a predetermined critical position, an outward turning direction is upward, and a inward turning direction is downward, fig. 5 is a state when the temple 6 is at a predetermined outward turning limit position, and fig. 7 is a state when the temple 6 is at a predetermined inward turning limit position. Alternatively, in fig. 5, the angle of rotation between the temple 6 and the frame 2 is B1; in fig. 6, the angle of rotation between the temple 6 and the frame 2 is B0, 0 < B0 < B1, B0 being a predetermined angle of rotation, more specifically B0 < 90 °; in fig. 7, the temple 6 and the frame 2 are parallel to each other with a rotation angle of 0.

During wearing, the user turns the temple 6 outwards, the elastic component is kept in an undeformed state at each position during the process that the temple 6 is turned outwards from the state shown in fig. 7 to the state shown in fig. 6, and is in a deformed state at each position during the process that the temple 6 is turned from the state shown in fig. 6 to the state shown in fig. 5, accordingly, the reset force of the elastic component causes the temple 6 to have a folding-in movement tendency, and after wearing, the head is positioned on the upper side of the temple 6 in the orientation of fig. 5, and the temple 6 can provide clamping force for the head.

The preset critical position can be analyzed and set in combination with the big data of the human body size, so that the glasses legs 6 can provide clamping force when most users wear the glasses.

In this embodiment, through add elastic component in the hinge subassembly, can make under the wearing state, two mirror legs 6 can the centre gripping head, avoid the intelligent glasses under the wearing state to drop, improve the reliability of wearing. In addition, because the elastic component begins to deform after the temples 6 are turned outwards to preset the corners, and does not deform within the preset corners, the elastic component can be in an undeformed loose state under the corners which are not suitable for wearing, and the service life of the elastic component can be prolonged.

Further, as shown in fig. 20, the hinge assembly further includes at least two connecting plates 31 arranged in sequence from front to back, the frontmost connecting plate 31 is connected to the frame 2, the rearmost connecting plate 31 is connected to the temple 6, specifically, the frontmost connecting plate 31 is inserted and screwed into the frame 2, the rearmost connecting plate 31 is inserted and screwed into the temple 6, the fixing is stable and reliable, and the number of screws can be at least two.

Note that, as described below, the front and rear between the frame 2 and the temple 6 are defined based on the positions of the frame 2 and the temple 6, and the frame 2 is in front and the temple 6 is in rear, and for example, the connecting plate 31 has a front end at the end close to the frame 2 and a rear end at the end close to the temple 6.

In addition, the elastic assembly comprises elastic pieces arranged between every two adjacent connecting plates 31, so that the elastic assembly is integrally deformed by matching different elastic pieces, and each connecting plate 31 bears a part of elastic pressure, thereby being beneficial to prolonging the service life of the hinge assembly. In this embodiment, there are 4 connecting plates 31, but in other embodiments, there may be two or other numbers of connecting plates 31.

Further, referring to fig. 3, the elastic member is a spring plate 32, which is convenient for processing. Specifically, the elastic piece 32 is located on a side of the connecting plate 31 away from the head in the wearing state. One end of the elastic sheet 32 is fixed on one of the connecting plates 31, and the other end is a free end and deforms by abutting against the other connecting plate 31.

Obviously, in other embodiments, the elastic element may also be a torsion spring sleeved on the connecting shaft 343 between the two connecting plates 31.

Further, the connecting plate 31 and the elastic sheet 32 are of a split structure. As shown in fig. 3, the elastic sheet 32 is screwed to the corresponding connecting plate 31, so as to facilitate replacement and maintenance of the elastic sheet 32. Because shell fragment 32 and connecting plate 31's split type setting, can reduce the elasticity requirement to connecting plate 31, connecting plate 31 has or not elasticity all can, specifically can select for use suitable stainless steel material according to the required intensity of in-service use, can prevent to rust, and in addition, the better stainless steel 304 of elastic property or stainless steel 301 can be selected for use to shell fragment 32.

Furthermore, in every two adjacent connecting plates 31, one of the connecting plates fixes the elastic sheet 32 in the middle in the axial direction, and the other connecting plate is provided with an elastic sheet groove 37 in the middle in the axial direction, and the elastic sheet 32 is deformed by extending into the elastic sheet groove 37 and abutting against the groove bottom of the elastic sheet groove 37. As shown in fig. 5, the groove bottom of the elastic sheet groove 37 forms a pressing surface 33 in press fit with the free end of the elastic sheet 32, so as to be abutted against the free end of the elastic sheet 32, and by separately providing the elastic sheet groove 37, it can be ensured that the temple 6 is in the state of the preset inflected limit position, and a sufficiently large distance is provided between the free end of the elastic sheet 32 and the pressing surface 33, so that in the process of changing the state of the temple 6 from fig. 7 to fig. 6, the free end of the elastic sheet 32 and the pressing surface 33 can be kept in a separated state, and the elastic sheet 32 cannot be pressed to the pressing surface 33 to deform.

Further, a plate rotation limiting structure is arranged between the adjacent connecting plates 31 to limit the relative rotation angle of the two adjacent connecting plates 31. Specifically, as shown in fig. 4 and 7, in two adjacent connecting plates 31, the plate rotation limiting structure includes a plate inward-folding limiting surface 381 and a plate outward-folding limiting surface 382 which are sequentially arranged on the front end surface of the subsequent connecting plate 31 along the direction away from the head in the wearing state, so as to facilitate processing. As shown in fig. 7, the rear connecting plate 31 can be turned inward until the upper plate inward-turning limiting surface 381 of the rear connecting plate 31 abuts against the rear end surface of the front connecting plate 31, so as to limit the maximum angle between the two adjacent connecting plates 31, and avoid the excessive turning angle of the single connecting plate 31 from causing the excessive bending angle and bending radius of each part of the electrical connector 5 between the spectacle frame 2 and the spectacle leg 6. As shown in fig. 4, the rear connecting plate 31 can be turned inside out until the turning-out limiting surface 382 of the upper plate abuts against the rear end surface of the front connecting plate 31 to limit the maximum angle between the two adjacent connecting plates 31, and the turning of each connecting plate 31 has the characteristics of large bending radius and small maximum angle of bending.

Further, the hinge assembly includes a hinge housing 4, both ends of which are respectively hinged to the frame 2 and the temple 6, the hinge housing includes a plurality of hinge sleeves 41, and the hinge sleeves 41 are annular sleeves penetrating in the front-rear direction. Specifically, the hinge assembly includes at least three connecting plates 31, and a hinge sleeve 41 fixedly secured to the outside of each connecting plate 31 between the front and rear connecting plates 31. As shown in fig. 10, in the present embodiment, there are 4 connecting plates 31, and one hinge sleeve 41 is fixedly connected to the outside of each of the two connecting plates 31 in the middle.

Wherein preferably the electrical connection 5 extends from the temple 6 through the inside of the hinge housing 4 and into the frame 2. By embedding the electric connection member 5 in the hinge case 4, the degree of exposure of the electric connection member 5 can be reduced, the electric connection member 5 can be effectively protected, and the risk of damage to the electric connection member 5 can be reduced.

In this embodiment, each hinge sleeve 41 is fixedly connected with the inner connecting plate 31 thereof and synchronously rotates, so that the connecting plate 31 can be prevented from randomly swinging in the hinge sleeve 41 and colliding with components such as the electric connecting piece in the hinge sleeve 41.

In addition, the spectacle frame 2 and the frontmost end connecting plate 31 and the spectacle legs 6 and the rearmost end connecting plate 31 are fixed by means of screw connection, welding connection, riveting connection or the like, and the fixing is stable and reliable. Since the hinge housings 41 are fixedly connected to the inner connecting plate 31 thereof, the frame 2 and the foremost hinge housing 41, and the temple 6 and the rearmost hinge housing 41 may not be directly fixedly connected.

Further, as shown in fig. 13, the adjacent connection plates 31 are rotatably connected by a positioning pin 363. Optionally, in two adjacent connection plates 31, a front plate insertion hole 361 is disposed at the rear end of the front connection plate 31, a rear plate insertion hole 362 is disposed at the front end of the rear connection plate 31, and both the front plate insertion hole 361 and the rear plate insertion hole 362 are sleeved on the positioning pin 363. Specifically, the front board jack 361 is fixedly connected with the positioning pin 363, and the front board jack 361 and the positioning pin 363 cannot rotate relatively after being sleeved; the rear plate insertion holes 362 are rotatably connected with the positioning pins 363, specifically in clearance fit, damping oil is added into the rear plate insertion holes 362, so that damping performance is embodied during bending, use hand feeling is increased, and finally the hinge plate group 3 formed by connecting the connecting plates 31 can rotate and have a smooth damping effect.

Further, for each connecting plate 31 on which the hinge sleeve 41 is fitted, at least one positioning pin 363 is axially projected from the connecting plate 31 and inserted into the outer hinge sleeve 41, as shown in fig. 13, the hinge sleeve 41 is fitted into the positioning pin 36 at the front end of the inner connecting plate 31 thereof, and is axially separated from the positioning pin 36 at the rear end of the connecting plate 31, and the freedom of movement of the hinge sleeve 41 relative to the inner connecting plate 31 thereof in the front-rear direction, that is, in the left-right direction in the orientation shown in fig. 13, can be restricted.

Further, sleeve stoppers are respectively arranged at two ends of the inner surface of the hinge sleeve 41 in the axial direction and at two ends close to and far from the head in a wearing state, so as to be correspondingly abutted against the outer surface of the connecting plate 31. As shown in fig. 11 to 13, the cover stopper includes a first stopper 441, a second stopper 442, a third stopper 443, and a fourth stopper 444 provided on the hinge cover 41. The first stopper 441 and the second stopper 442 axially limit the connecting plate 31 from both sides of the connecting plate 31, and the third stopper 443 and the fourth stopper 444 respectively limit the connecting plate 31 from both sides of the connecting plate 31 that are close to and away from the head in a wearing state. More specifically, the second stopper 442, the third stopper 443, and the fourth stopper 444 may be butted to form a U-shaped groove that opens toward the first stopper 441. The hinge sleeve 41 and the inner connecting plate 31 are fixedly connected into an integral moving structure through the limit of each set of limit block and the position fixing pin 363.

Further, as shown in fig. 9 and 12, a C-shaped groove 45 with a forward opening is formed at the front end in the hinge sleeve 41, the hinge sleeve 41 can be sleeved outside the corresponding connecting plate 31 from back to front until the C-shaped groove 45 is correspondingly fastened with the positioning pin 363 at the front end of the connecting plate 31, the positioning pin 363 is connected to the hinge sleeve 41 through the C-shaped groove 45, and the positioning pin 363 is arranged in the C-shaped groove 45, so that the determination of the sleeving end position of the hinge sleeve 41 on the connecting plate 31 is facilitated.

Further, the hinge cover 41 is provided with attachment passages penetrating in the front-rear direction, and the inner space of the temple 6 communicates with the inner space of the frame 2 through the respective attachment passages. Specifically, the first stopper 441 and the third stopper 443 are provided with a space therebetween in the axial direction, and the space constitutes a mounting passage that penetrates in the front-rear direction to accommodate the electric connection member 5 and the like built in the hinge case 4. In the hinge sleeve 41, the installation channel can be connected or disconnected with the space of the connecting plate 31.

Further, be connected with flexible heat-conducting piece 1 between picture frame 2 and mirror leg 6, flexible heat-conducting piece 1 specifically is the material that high heat conduction, the buckling many times such as flexible graphite flake, flexible graphite alkene, can pass through flexible heat-conducting piece 1 with the heat of 2 sides of picture frame that calorific capacity is great, the temperature is higher to the mirror leg 6 sides that generate heat less, the temperature is lower, reduces the temperature of 2 sides of picture frame, makes the whole temperature of intelligent glasses more balanced, can improve user experience.

Preferably, the flexible heat conducting member 1 is embedded in the hinge shell 4, and particularly, the temple 6 can penetrate through the mounting channel of each hinge sleeve 41 and extend into the spectacle frame 2, so that the hinge shell 4 can shield the electric connecting member 5 and the connecting plate 31, and can wrap the flexible heat conducting member 1, thereby protecting the flexible heat conducting member 1. More specifically, one end of the flexible heat conducting member 1 is fixed to the spectacle frame 2, and is specifically directly fixed to a heat conducting component such as a heat generating component or a heat pipe in the spectacle frame 2, and the other end of the flexible heat conducting member 1 is fixed to the spectacle leg 6, and is specifically fixed to the inner surface of the spectacle leg 6.

Further, the frame 2, the hinge sleeves 41 and the temples 6 are connected in sequence from front to back to form a housing assembly, the frame 2, the hinge sleeves 41 on the left side and the temples 6 on the left side form a housing assembly on the left side, and the frame 2, the hinge sleeves 41 on the right side and the temples 6 on the right side form a housing assembly on the right side.

Further, in the housing assembly, a housing rotation limiting structure is respectively arranged between every two adjacent components to respectively limit the relative rotatable angles of the two adjacent components, because the hinge sleeve 41 is fixedly connected with the connecting plates inside the hinge sleeve, the housing rotation limiting structure and the plate rotation limiting structure can be correspondingly arranged, so that the housing rotation limiting structure is matched with the plate rotation limiting structure, when the glasses leg 6 rotates inwards (or outwards) relative to the glasses frame 2, when the two adjacent connecting plates 31 inwards (or outwards) rotate to the angle limited by the plate rotation limiting structure, the two corresponding adjacent components in the housing assembly inwards (or outwards) rotate to the angle limited by the housing rotation limiting structure, and the rotation limiting reliability is further improved.

Further, referring to fig. 2, 11 and 12, in each two adjacent components of the housing assembly, one of the two adjacent components is provided with a connecting protrusion, the other is provided with a connecting groove, and the connecting groove is rotatably sleeved outside the connecting protrusion. That is to say, the spectacle frame 2 and the foremost hinge sleeve 41, the adjacent hinge sleeve 41, and the rearmost hinge sleeve 41 and the spectacle leg 6 are all connected in a sleeved manner, so that the sealing effect of the butt joint of any adjacent two in the housing component can be improved, and the protection effect on the electric connecting piece 5 can be further ensured.

Preferably, the temple 6 is in a state of any rotatable angle relative to the frame 2, and the side close to the head and the side far away from the head in the wearing state between the two adjacent shell components are partially overlapped in area, so that the hinge shell 4 always has a good shielding effect on the internal components in each state, and the appearance of the equipment is attractive.

Specifically, in the housing assembly, between the adjacent two members, the former has a connecting protrusion at the rear end, such as the frame connecting protrusion 22 at the end of the frame 2 in fig. 2 and the sleeve connecting protrusion 461 at the rear end of each hinge sleeve 41 in fig. 11, and the latter has a connecting recess at the front end, such as the sleeve connecting recess 462 at the front end of each hinge sleeve 41 in fig. 11 and the temple connecting recess at the front end of the temple 6. Of course, in other embodiments, as shown in fig. 27, in the housing assembly, between two adjacent components, the former is provided with a connecting groove at the rear end, and the latter is provided with a connecting projection at the front end.

Furthermore, in the end face of the notch of the connecting groove, one end close to the head in a wearing state forms an inward-folding limiting face, and one end far away from the head forms an outward-turning limiting face, so that the connecting protrusion can move inward to abut against the inward-folding limiting face and move outward to abut against the outward-turning limiting face.

Specifically, taking the limitation between two adjacent hinge sleeves 41 as an example, as shown in fig. 15 and 17, a sleeve inward-folding limiting surface 471 and a sleeve outward-folding limiting surface 472 are arranged on the latter hinge sleeve 41, and in the inward-folding rotation process of the temple 6, after the sleeve inward-folding limiting surface 471 on the latter hinge sleeve 41 is abutted against the former hinge sleeve 41 (specifically, the outer surface of the connecting protrusion thereon), the latter hinge sleeve 41 cannot be continuously folded and rotated inward; in the process of outward turning of the temple 6, after the outward turning limit surface 472 of the sleeve body on the rear hinge sleeve 41 abuts against the front hinge sleeve 41 (specifically, the step surface on the front hinge sleeve butted with the front end of the connecting protrusion), the rear hinge sleeve 41 cannot continue outward turning.

Further, referring to fig. 15 and 17, at least one of the inner surface of the coupling groove and the outer surface of the coupling protrusion includes a circular arc surface, and the circular arc surface is collinear or parallel with a rotation center line between the coupling groove and the coupling protrusion. Through the setting of arc surface, can improve two adjacent parts pivoted smoothness nature in the shell subassembly, avoid taking place to interfere between the two.

Specifically, as shown in fig. 15, the rotation center line S of the connecting groove and the connecting protrusion is used as a center line, and the side (i.e., the lower side in fig. 15) close to the head and the side (i.e., the upper side in fig. 15) far from the head in the worn state in the inner surface of the connecting groove are arc surfaces each using the rotation center line S as a center line, wherein the radius and the arc length of each arc surface are determined according to the radial distance from the rotation center line S, as shown in fig. 15, the distance from the lower side arc surface of the connecting groove to the rotation center line S is greater than the distance from the upper side arc surface to the rotation center line S, and the radius and the arc length of the lower side arc surface are also set to be greater than the radius and the arc length of the upper side.

In addition, as for the outer peripheral surface of the coupling projection, the side of the outer surface of the coupling projection which is away from the head in the wearing state (i.e., the upper side in fig. 15) is an arc surface having the rotation center line S as the center line. The size relation between the radius of the arc surface on the connecting protrusion and the radius of the corresponding arc surface on the connecting groove can be set as required. Optionally, the radius of the arc surface on the upper side of the connecting protrusion and the radius of the arc surface on the upper side of the connecting groove can be set to be the same or slightly smaller than the radius of the arc surface on the upper side of the connecting groove, so that in the process of turning the temple 6 outwards, the outward turning limiting surface 472 of the sleeve body on the connecting groove can smoothly rotate to abut against the step surface butted with the front end of the front connecting protrusion to limit turning.

Further, as for the portion of the outer peripheral surface of the joining projection on the side closer to the head (i.e., the lower side in fig. 15), it is preferably provided as a circular arc surface but its circular center line is another straight line parallel to the rotation center line S, and may be provided as a flat surface in other embodiments. Alternatively, as shown in fig. 15, the curvature of the lower arc surface of the connecting protrusion is smaller than that of the lower arc surface of the outer connecting groove, so that during the inward folding and rotating process of the temple 6, the sleeve inward folding limiting surface 471 (specifically, the upper edge line thereof) on the connecting groove can rotate to abut against the lower arc surface of the front connecting protrusion to limit the rotation.

Of course, in other embodiments, the inner surface of the connecting groove and the outer surface of the connecting protrusion may be provided as a spherical surface which is fitted to each other, so as to improve the sealing performance between the two.

In addition, in other embodiments, for rotation limitation between the temple and the spectacle frame, a rotation limitation structure of the outer shell may not be provided between the components in the outer shell component, and the rotation limitation of the temple 6 is realized only by the rotation limitation structure of the plate provided between the connecting plates 31, or the rotation limitation of the temple 6 is realized only by the rotation limitation structure of the outer shell without providing the rotation limitation structure of the plate between the connecting plates 31.

In the second embodiment of the smart glasses provided by the present invention, please refer to fig. 21 to 32, the structure of the elastic sheet 32 and the connecting plate 31 can be set differently from the above embodiments. Optionally, the elastic piece 32 is integrally formed on the connecting plate 31. Specifically, the connecting plate 31 has elasticity, and stainless steel plates with different thicknesses can be selected according to the strength required by actual use, so that the connecting plate 31 is ensured to have good elasticity and the strength also meets the use requirement. In addition, the connecting plate 31 is realized by adopting a sheet metal bending process, and has the advantages of simple structural design shape, simple manufacture, low cost, high efficiency, high manufacturing precision and good mass production.

Further, of every two adjacent connecting plates 31, one of the rear end of the previous connecting plate 31 and the front end of the next connecting plate 31 is bent toward the side away from the head in the wearing state at the middle part in the axial direction to form the elastic piece 32, while the two ends are turned toward the side close to the head in the wearing state to form the second connecting ring 342, and the other is turned toward the side away from the head in the wearing state at the middle part in the axial direction to form the first connecting ring 341. The first connection ring 341 and the second connection ring 342 are sleeved on the connection shaft 343, and the first connection ring 341 is located between the two second connection rings 342, so as to realize rotational connection. That is to say, the portion of the connecting plate 31 for connecting with the connecting shaft 343 is an integral structure with the connecting plate 31, and the connecting with the connecting shaft 343 can be realized by the curling thereof, so that the processing can be further facilitated, and the number of parts required by the equipment can be reduced.

As shown in fig. 22, in the butt joint of the two connection plates 31, a first connection ring 341 is disposed at the rear end of the previous connection plate 31, a second connection ring 342 is disposed at the front end of the next connection plate 31, a pressing surface 33 that is matched with the elastic sheet 32 and presses is formed on the side of the previous connection plate 31 away from the head in the wearing state, and based on the turning direction of the first connection ring 341, the pressing surface protrudes toward the side away from the head in the wearing state relative to the pressing surface 33, so that it can be ensured that the free end of the elastic sheet 32 has a sufficiently large distance from the pressing surface 33 in the state where the temple 6 is located at the preset inward-folding limit position, and thus in the process that the state of the temple 6 changes from fig. 26 to fig. 25, the free end of the elastic sheet 32 and the pressing surface 33 can be kept in a separated state, and the.

Preferably, between two adjacent connecting plates 31, the second connecting ring 342 is tightly fitted and fixed with the connecting shaft 343, i.e. the fixed connection between the two cannot rotate relatively. First connecting ring 341 rotates with connecting axle 343 to be connected, first connecting ring 341 and connecting axle 343 interference fit promptly, but can rotate relatively and possess certain frictional force, specifically can add damping oil in first connecting ring 341, because there is frictional force to exist, can embody smooth damping nature when buckling, increase and use and feel for the chain structure that each connecting plate 31 connects the formation possesses smooth damping effect rotatable simultaneously.

Wherein, preferably, a plate rotation limiting structure is provided between adjacent connecting plates 31 to limit the angle at which two adjacent connecting plates 31 can rotate relatively. As shown in fig. 24 to 26, between adjacent connecting plates 31, the plate rotation limiting structure includes a rotation limiting groove 351 provided on the second connecting ring 342 and a spring plate limiting protrusion 352 provided on the spring plate 32, and the spring plate limiting protrusion 352 is inserted into the rotation limiting groove 351. As shown in fig. 26, the latter connecting plate 31 can be turned inward relative to the connecting shaft 343 to the end face of the rotation limiting groove 351 to abut against the elastic piece limiting protrusion 352, so as to limit the maximum angle between the two adjacent connecting plates 31, and avoid the excessive turning angle and bending radius of each part of the electrical connector 5 between the spectacle frame 2 and the spectacle leg 6 caused by the excessive turning angle of the single connecting plate 31. As shown in fig. 24, the latter connecting plate 31 can be turned outwards relative to the connecting shaft 343 until the other end surface of the rotation limiting groove 351 abuts against the spring plate limiting protrusion 352 to limit the maximum angle between two adjacent connecting plates 31, and the rotation of each connecting plate 31 has the characteristics of large bending radius and small maximum angle of bending.

In addition, the connection mode of the components and the connection mode of the connection plates in the housing assembly are not limited to the mode according to the first embodiment. As shown in fig. 27, the hinge housing 4 includes at least two hinge sleeves 41, one of the inner surface of the connecting groove and the outer surface of the connecting protrusion is provided with a rotating shaft groove, and the other is fixed with a rotating shaft post rotatably inserted in the rotating shaft groove, so as to realize the rotating connection between the hinge sleeve 41, the temple 6 and the eyeglass frame 2, and the reliability of the connection is not affected by the internal structure of the hinge housing 4, as shown in fig. 27, two end surfaces in the axial direction on the sleeve connecting protrusion 461 are respectively provided with one hinge rotating shaft groove 42, and the two hinge rotating shaft grooves 42 define the rotating center lines of the sleeve connecting protrusion 461 and the sleeve connecting groove 462, and the sleeve connecting groove 462 is provided with a hinge rotating shaft post 43 engaged with and inserted in each hinge rotating shaft groove 42.

That is, the components in the housing assembly are hinged through the matching of the hinge rotating shaft column 43 and the hinge rotating shaft slot 42, the connecting plate 31 is hinged through the connecting shaft 343, the hinge rotating shaft column 43 and the connecting shaft 343 are different components, and the swinging of the components in the housing assembly and the swinging of the hinge plate group 3 formed after the connecting plate 31 is connected may not be completely synchronous.

Obviously, in other embodiments, the hinge housing 4 can be provided with a hinge sleeve 41 to cover the hinge plate set 3 and the electrical connector, the flexible heat conducting member 1, etc., however, this embodiment can share the eversible angle between the temple 6 and the frame 2 by the rotation of different hinge sleeves 41, respectively, so as to improve the flexibility of the hinge rotation. In addition, the hinge sleeve 41 is annular and can sleeve the electric connecting piece 5, so that the protection effect on the electric connecting piece 5 can be improved.
