The smart glasses and the folding mechanism thereof provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1-20, the present disclosure provides a folding mechanism that includes a first portion 100, a second portion 200, and a first hinge mechanism 300.

The first hinge mechanism 300 rotatably connects the first and

second parts

100 and 200 such that the first and

second parts

100 and 200 can be relatively rotated, thereby folding the first and

second parts

100 and 200 and unfolding the first and

second parts

100 and 200.

The first hinge mechanism 300 includes a first hinge housing 310, a cover 320, and an elastic part 330. The first hinge housing 310 may be provided as an external structure of the first hinge mechanism 300, and may protect internal structures in the first hinge mechanism 300 and support the internal structures of the first hinge mechanism 300. The first hinge housing 310 defines a hinge cavity 311 and an opening 312, wherein the opening 312 communicates the hinge cavity 311 with the external environment of the first hinge housing 310. The cover 320 can be matched with the opening 312 of the first hinge housing 310 to seal the hinge cavity 311, so that the connection parts of the first part 100, the second part 200 and the first hinge mechanism 300 are covered, the external ornamental performance of the folding mechanism is improved, and meanwhile, the cover 320 is arranged to help workers to install and detach the folding mechanism. The elastic portion 330 connects the cover 320 and at least one of the first portion 100 and the second portion 200, such that the cover 320 and at least one of the first portion 100 and the second portion 200 can be connected, such that the elastic portion 330 can drive the cover 320 to move relative to at least one of the first portion 100 and the second portion 200 to cover the opening 312 when at least one of the first portion 100 and the second portion 200 rotates relative to the first hinge mechanism 300.

The first part 100 and the second part 200 are rotatably connected by a first hinge mechanism 300, and a connection area is defined between the two, the first hinge mechanism 300 is provided with a movable part which can move relative to the first part 100 and/or the second part 200, and the movable part can shield at least part of an exposed area which is in the connection area and is communicated with the outside, so that the exposed area can not be observed from the outside during the relative rotation of the first part 100 and the second part 200.

In another embodiment, the first hinge mechanism 300 rotatably connects the first part 100 and the second part 200 such that the first part 100 and the second part 200 can rotate relative to each other, and the first hinge mechanism 300 includes a fixed magnet and a movable magnet that are engaged with each other, and the movable magnet is movable relative to the first part 100 and/or the second part 200 to shield at least a portion of an exposed region of the connection region that communicates with the outside during the relative rotation of the first part 100 and the second part 200.

When the first and

second parts

100 and 200 are relatively rotated, at least one of the first and

second parts

100 and 200 is relatively rotated with respect to the connection part of the first hinge housing 310. Only the first portion 100 may rotate relative to the connection portion of the first hinge housing 310, only the second portion 200 may rotate relative to the connection portion of the first hinge housing 310, or both the first portion 100 and the second portion 200 may rotate relative to the first hinge housing 310, such that the elastic portion 330 connected to at least one of the cover 320, the first portion 100, and the second portion 200 is elastically deformed, and the elastic deformation at this time can generate a driving force for the cover 320, such that the cover 320 can move relative to at least one of the first portion 100 and the second portion 200 to cover the opening 312. It is understood that the first hinge mechanism 300 connects the first and

second parts

100 and 200, and the opening 312 of the first hinge mechanism 300 is defined between at least one of the first and

second parts

100 and 200 and the outer wall of the first hinge housing 310. During relative rotation of the first and

second portions

100, 200, the size of the opening 312 also changes with the rotation. Under the continuous driving of the elastic part 330, the cover 320 can move relative to at least one of the first part 100 and the second part 200, so as to always maintain the opening 312 in a covered state.

The folding mechanism disclosed in the embodiment of the present disclosure improves the structure of the folding mechanism in the related art, and by providing the first portion 100, the second portion 200, and the first hinge mechanism 300 including the first hinge housing 310, the cover 320, and the elastic portion 330 in the folding mechanism, the hinge cavity 311 of the first hinge mechanism 300 can be always covered by the cover 320 during the rotation of the folding mechanism, so that the internal structure at the part of the folding mechanism can be prevented from being exposed.

In the folding mechanism disclosed in the embodiment of the present disclosure, the first portion 100 may be rotatably coupled to the first hinge housing 310, and the second portion 200 may be rotatably coupled to the first hinge housing 310. The first portion 100 (or the second portion 200) can rotate with the first hinge housing 310 to an extended position, wherein the first portion and the second portion extend along a substantially same straight line, or the first portion 100 (or the second portion 200) can rotate with the first hinge housing 310 to a folded position, wherein an angle between the first portion and the second portion can be in a range of about 90 degrees to about 180 degrees. In this case, the rotation relationship between the first part 100, the second part 200 and the first hinge housing 310 is flexible, i.e. the folding mechanism has more folding methods to achieve the final folding purpose of the folding mechanism. The user may only fold the first portion 100 with respect to the first hinge housing 310, may only fold the second portion 200 with respect to the first hinge housing 310, and may also simultaneously fold the first portion 100 and the second portion 200 with respect to the first hinge housing 310, and the folding method between the first portion 100, the second portion 200, and the first hinge housing 310 is not limited in the embodiments of the present disclosure.

It is to be understood that the "folding mechanism" described in this disclosure refers to a mechanism having two parts that can rotate relative to each other, and may also be referred to as a hinge mechanism.

In order to simplify the folding operation of the folding mechanism, in the folding mechanism disclosed in the embodiment of the present disclosure, the first portion 100 may be fixedly connected to the first hinge housing 310 (e.g., the upper folding mechanism shown in fig. 1, 2, and 3), and the second portion 200 may be rotatably connected to the first hinge housing 310, so that only the second portion 200 and the first hinge housing 310 can rotate relative to each other. When the folding mechanism is folded, the user only needs to fold the second part 200 or the part of the first part 100 fixedly connected to the first hinge housing 310.

In one example, one of the first and

second portions

100 and 200 can be a unitary structure with the first hinge housing 310 (e.g., the upper portion folding mechanism shown in fig. 4), and the other of the first and

second portions

100 and 200 can be pivotally coupled to the first hinge housing 310. The folding mechanism is convenient to produce and manufacture due to the partial integrated structure, meanwhile, the folding mechanism is also convenient for workers to assemble, and when the folding mechanism breaks down, the folding mechanism is convenient for the workers to disassemble, so that the assembling performance of the folding mechanism can be improved.

The hinge housing 310 may be connected to the first portion 100 and/or the second portion 200 by a screw 900, the screw 900 may have a partial thread, the threaded portion is fixedly connected to the first portion 100 and/or the second portion 200, and the smooth portion is rotatably connected to the hinge housing 310.

In the folding mechanism disclosed in the embodiment of the present disclosure, the first portion 100 may have the first channel 110, the second portion 200 may have the second channel 210, and the hinge cavity 311 communicates the first channel 110 and the second channel 210. In this case, the first channel 110 and the second channel 210 are disposed such that there is a space in the first portion 100 and the second portion 200 for rotational connection with the first hinge mechanism 300, the hinge cavity 311 is disposed such that there is a space in the first hinge mechanism 300 for rotational connection with the first portion 100 and the second portion 200, such that a larger continuous space is defined inside the folding mechanism, which can allow larger or more components (e.g., flexible circuit boards, thicker cables, etc.) to be accommodated inside the folding mechanism, and the components can extend from the first portion 100 of the folding mechanism through the first hinge mechanism 300 and the second portion 200.

In the folding mechanism disclosed in the embodiment of the present disclosure, as shown in fig. 6 to 11, the folding mechanism may further include a limiting portion 600, the limiting portion 600 is disposed in the opening 312, and the elastic portion 330 drives the cover body 320 to elastically abut against the limiting portion 600. In this case, the limiting portion 600 can limit the movement of the cover 320, so that when the first portion 100 and the second portion 200 rotate relatively, the cover 320 can avoid excessive movement caused by insufficient stability of the driving force of the elastic portion 330, and thus the stability of the cover 320 in the operation process of the folding mechanism can be improved.

In the folding mechanism disclosed in the embodiment of the present disclosure, at least one of the first portion 100 and the second portion 200 may be provided with a guide 120, as shown in fig. 5, the guide 120 and an inner wall of at least one of the first portion 100 and the second portion 200 form a guide channel 500, and the cover body 320 is slidably fitted to the guide channel 500. In this case, the cover 320 can slide along the guide channel 500 relative to the guide 120, that is, the cover 320 can slide relative to at least one of the first portion 100 and the second portion 200, so that at least one of the first portion 100 and the second portion 200 can rotate relative to the first hinge mechanism 300. Moreover, the arrangement of the guide channel 500 facilitates the cover 320 to regularly slide in at least one of the first portion 100 and the second portion 200, so that an obstacle of relative rotation between the first portion 100 and the second portion 200 caused by a change of a sliding track of the cover 320 in at least one of the first portion 100 and the second portion 200 can be avoided, and further, the stability of the operation of the folding mechanism can be improved.

In the folding mechanism disclosed in the embodiment of the present disclosure, as shown in fig. 8 and 9, the folding mechanism may further include an elastic body 340, the elastic body 340 is provided to at least one of the first portion 100 and the second portion 200, and the elastic body 340 elastically interferes with the first hinge housing 310. When at least one of the first part 100 and the second part 200 rotates relative to the first hinge mechanism 300, the elastic body 340 elastically interferes with the first hinge housing 310 under the action of elasticity, so that during the relative rotation of at least one of the first part 100 and the second part 200 relative to the first hinge mechanism 300, the elastic body 340 can have a better limiting effect on the first hinge housing 310, and therefore, the stable position relationship between at least one of the first part 100 and the second part 200 and the first hinge mechanism 300 is favorably maintained. When the user rotates the folding mechanism, the user can feel damped.

In one embodiment, the elastic body 340 may be a bent elastic sheet, as shown in fig. 8 and 9, a bent portion facing the first hinge housing 310 is formed in the middle of the bent elastic sheet, and the bent portion of the bent elastic sheet is in elastic contact with the first hinge housing 310. When at least one of the first part 100 and the second part 200 rotates relative to the first hinge mechanism 300 to switch between the unfolded state and the folded state, the bending portion of the bending spring is compressed. The minimum amount of compression of the bending part in the unfolding state and the folding state is beneficial to the folding mechanism to maintain the position of the folding mechanism in the folding or unfolding state. As the relative rotation between the first portion 100 and the second portion 200 occurs, the amount of compression of the bending portion gradually increases from a minimum value to a maximum value. Then, due to further relative rotation between the first portion 100 and the second portion 200, the amount of compression of the bending portion will gradually decrease from the maximum value to the minimum value. For example, the amount of compression of the bending portion is maximized when at least one of the first and

second portions

100 and 200 is at an angle of about 45 degrees relative to the first hinge mechanism 300.

In one example, at least one of the first and

second parts

100 and 200 may be provided with a positioning part 400 for fixing the elastic body 340, as shown in fig. 8 and 9, the positioning part 400 can fix the elastic body 340, so that the position of the elastic body 340 can be prevented from being moved during the elastic interference with the first hinge housing 310. For example, the positioning part 400 may be two insertion grooves provided on a sidewall of at least one of the first and

second parts

100 and 200, and both ends of the elastic body 340 may be respectively inserted into the two insertion grooves.

In the folding mechanism disclosed in the embodiment of the present disclosure, in order to have a better matching effect between the position-limiting portion 600 and the cover body 320, as shown in fig. 10, the position-limiting portion 600 may be provided with a rolling body 610. When at least one of the first part 100 and the second part 200 rotates relative to the first hinge mechanism 300, the elastic part 330 can drive the cover 320 to contact with the rolling body 610 of the position-limiting part 600 in a rolling manner, so that the problem that the cover 320 moves relative to the first hinge housing 310 to cause an improper fit relation with the position-limiting part 600 can be avoided. Alternatively, the cover 320 may be provided with a rolling element 324, and when at least one of the first part 100 and the second part 200 and the first hinge mechanism 300 rotate relatively, the elastic part 330 can drive the rolling element 324 of the cover 320 to contact with the limiting part 600 in a rolling manner, so as to avoid the problem that the cover 320 moves relative to the first hinge housing 310 and causes an improper fit relation with the limiting part 600. Such rolling contact can be beneficial to solving the problem of mutual wear between components.

In one example, the rolling body 610 may be a hollow shaft, as shown in fig. 11, the rolling body 610 is connected to the cover body 320 or the stopper portion 600 through a first connection shaft 620 penetrating the cover body 320 or the stopper portion 600, the first connection shaft 620 penetrates the rolling body 610, and the rolling body 610 is rotatably engaged with the first connection shaft 620. In this case, the rolling body 610 of the hollow shaft is beneficial to connect the rolling body 610 to the cover body 320 or the limiting portion 600 through the first connecting shaft 620, and the rotational fit between the first connecting shaft 620 and the rolling body 610 can help to promote the fit relationship between the rolling body 610 and the cover body 320, so that the stability of the connection of the rolling body 610 on the first hinge mechanism 300 can be promoted.

In one example, the cover body 320 may be provided with a first protrusion 323, as shown in fig. 5, the first protrusion 323 is in limit-fitting with the guide 120 at a port facing away from the limit part 600. In this case, the first protrusion 323 can be pre-limited with the guide channel 500, so as to help the cover body 320 to be matched with the guide channel 500, thereby facilitating the precise matching of the cover body 320 and the guide channel 500.

In the folding mechanism disclosed in the embodiment of the present disclosure, as shown in fig. 5, the cover body 320 may be provided with a first positioning structure 325, an inner wall of at least one of the first portion 100 and the second portion 200 may be provided with a second positioning structure 220, a first end of the elastic part 330 may be in positioning engagement with the first positioning structure 325, and a second end of the elastic part 330 may be in positioning engagement with the second positioning structure 220.

In the above situation, the first end and the second end of the elastic part 330 are respectively in positioning engagement with the first positioning structure 325 and the second positioning structure 220, so that the elastic part 330 has a definite elastic deformation path, and thus the elastic part 330 can have a definite driving direction for at least one of the cover 320, the first portion 100 and the second portion 200, and therefore the accuracy of the engagement between at least one of the cover 320, the first portion 100 and the second portion 200 is higher.

For better positioning effect of the elastic part 330 in at least one of the cover 320, the first part 100 and the second part 200, the first positioning structure 325 may be a second protrusion, the second positioning structure 220 may be a third protrusion, the first end of the elastic part 330 may be sleeved on the second protrusion and be in positioning fit with the second protrusion, the second end of the elastic part 330 may be sleeved on the third protrusion and be in positioning fit with the third protrusion, so that the size of the elastic part 330 that is elastically deformed is small, and the path of the elastic deformation and the elastic deformation recovery is more accurate.

In another embodiment, the first positioning structure 325 may be a first positioning groove, the second positioning structure 220 may be a second positioning groove, the first end of the elastic portion 330 may be inserted into the first positioning groove, and the second end of the elastic portion 330 may be inserted into the second positioning groove. In this case, two ends of the elastic portion 330 are respectively inserted into the first positioning groove and the second positioning groove, so that the two ends of the elastic portion 330 can be positioned and fixed in the first positioning groove and the second positioning groove, and the size of the elastic portion 330, which can be elastically deformed, can be reduced, thereby improving the accurate driving of the elastic portion 330 to at least one of the cover 320, the first portion 100, and the second portion 200.

In the folding mechanism disclosed in the embodiment of the present disclosure, the inner wall of at least one of the first portion 100 and the second portion 200 may be opened with a receiving groove 130, and the elastic portion 330 may be disposed in the receiving groove 130. In this case, the accommodating groove 130 can fix and position the elastic portion 330 better, and at the same time, the elastic portion 330 can only deform elastically in the accommodating groove 130, so that the elastic driving function of the elastic portion 330 can be better exerted.

In one example, as shown in fig. 10, the stopper 600 may partition the opening 312 into a first sub-opening 312a and a second sub-opening 312 b. The first sub opening 312a and the second sub opening 312b may communicate with the hinge cavity 311 and the external environment of the first hinge housing 310.

The elastic part 330 may include a first elastic member 331 and a second elastic member 332, the first elastic member 331 being connected to the first part 100, and the second elastic member 332 being connected to the second part 200. The cap body 320 may include a first cap portion 321 and a second cap portion 322, the first cap portion 321 being connected to the first elastic member 331, and the second cap portion 322 being connected to the second elastic member 332. In this example, both the first and

second portions

100, 200 are rotatable relative to the first hinge housing 310 such that the first and

second portions

100, 200 can be rotated relative to the first hinge housing 310 to an extended state in which the first and

second portions

100, 200 are substantially parallel and collinear with each other and a folded state in which the first and

second portions

100, 200 are substantially parallel and overlapping with each other, i.e., substantially folded in half.

In this example, when the first part 100 rotates relative to the first hinge mechanism 300, the rotation of the first part 100 can drive the first elastic member 331 to generate elastic deformation, so that the first elastic member 331 can drive the cover 320 to move relative to the first part 100 to cover the first sub-opening 312a, and the first sub-opening 312a is always kept in a closed state when the first part 100 and the second part 200 rotate relative to each other. When the second portion 200 rotates relative to the first hinge mechanism 300, the second elastic member 332 is driven by the rotation of the second portion 200 to generate elastic deformation, so that the second elastic member 332 can drive the cover 320 to move relative to the second portion 200 to cover the second sub-opening 312b, and the second sub-opening 312b can be always kept in a closed state when the first portion 100 and the second portion 200 rotate relative to each other.

Based on the folding mechanism described above, the disclosed embodiments disclose smart glasses, which may include a glasses body 700 and temples 800, as shown in fig. 13 to 16. The glasses body 700 may include main functional structures of the smart glasses, such as an image source, an optical module, a lens, a frame, and the like. The temples 800 can help the user wear the smart glasses. The temples 800 and the glasses bodies 700 may be connected by any of the folding mechanisms described above, so that the relative folding between the temples 800 and the glasses bodies 700 can be achieved to facilitate the storage when the smart glasses are not used. Because the folding mechanism can not expose the internal structure of the intelligent glasses in the unfolding state and the folding state, the internal structure of the intelligent glasses can be protected.

The disclosed embodiment also discloses a pair of smart glasses, which can comprise a glasses body 700 and a glasses leg 800, wherein the glasses leg 800 and the glasses body 700 are connected through the folding mechanism. Temple 800 may include a first temple 810 and a second temple 820, with first temple 810 and second temple 820 connected via a folding mechanism as described above, e.g., with spring 330 including first spring 331 and second spring 332, and cover 320 including a folding mechanism for first cover portion 321 and second cover portion 322. In this case, the first and

second temples

810 and 820 can complete folding of the temple 800 through the folding mechanism, so that the first and

second temples

810 and 820 can be substantially folded in half, and the temple 800 can also complete folding relative to the glasses body 700 through the folding mechanism, and finally, the smart glasses can occupy less space after being folded and can not expose the internal structure during folding, so as to protect the internal structure.

The present disclosure also discloses smart glasses, which may include a glasses body 700 and a glasses leg 800, the glasses leg 800 being connected with the glasses body 700, the glasses leg 800 may include a first glasses leg 810 and a second glasses leg 820, and the first glasses leg 810 and the second glasses leg 820 are connected through the above-mentioned partial folding mechanism. In this case, the folding of the temple 800 between the first temple 810 and the second temple 820 can be achieved by a folding mechanism, so that the temple 800 occupies less space, thereby enabling the folding accommodation of the temple 800.

In the smart glasses disclosed in the embodiments of the present disclosure, the glasses body 700 may include a first body part 710, a second body part 720, and a second hinge mechanism 730, and the second hinge mechanism 730 rotatably connects the first body part 710 and the second body part 720. In this case, the first body part 710 and the second body part 720 can be folded by rotating relative to the second hinge mechanism 730, so that the temple 800 and the glasses body 700 can be folded by the second hinge mechanism 730, and the smart glasses can be stored in a smaller space after being folded, thereby improving the storage performance of the smart glasses.

In one example, as shown in fig. 17-20, the second hinge mechanism 730 can include a second hinge housing 731, and the second hinge housing 731 can be an outer structure of the second hinge mechanism 730 that can protect an inner structure of the second hinge mechanism 730. The first end of the second hinge housing 731 is rotatably coupled to the first body portion 710 via a first hinge axis, the second end of the second hinge housing 731 is rotatably coupled to the second body portion 720 via a second hinge axis, and the first end of the second hinge housing 731 is disposed opposite to the second end of the second hinge housing 731. In this case, the first body part 710 can be rotatably connected to the second hinge housing 731 by the first hinge shaft, the second body part 720 can be rotatably connected to the second hinge housing 731 by the second hinge shaft, and since the first end and the second end of the second hinge housing 731 are disposed opposite to each other, the first body part 710 and the second body part 720 can be relatively disposed after being rotated with respect to the second hinge housing 731, and the folding in half can be achieved to reduce the storage size. Moreover, the internal structures of the first body part 710 and the second body part 720 are shielded by the external structures of the first body part 710 and the second body part 720, so that the safety performance of the smart glasses during storage can be improved.

In the intelligent glasses provided by the embodiment of the present disclosure, the first end of the second hinge housing 731 has a first avoiding hole 732, the second end of the second hinge housing 731 has a second avoiding hole 733, the first hinge shaft passes through the first avoiding hole 732 and is in a rotational fit with the first avoiding hole 732, the first avoiding hole 732 is in a sliding fit with the first hinge shaft, the second hinge shaft passes through the second avoiding hole 733 and is in a rotational fit with the second avoiding hole 733, and the second avoiding hole 733 is in a sliding fit with the second hinge shaft. In this case, the first avoidance hole 732 and the first body part 710 are slidably engaged with each other by a first hinge shaft, and the second avoidance hole 733 and the second body part 720 are slidably engaged with each other by a second hinge shaft, so that the first body part 710 and the second body part 720 can be relatively folded and unfolded by slidably engaging with the second hinge housing 731.

The rotation axis of the first body 710 and the second body 720 with respect to the second hinge mechanism 730 is a first rotation axis, and the rotation axis of the first temple 810 and the second temple 820 with respect to the first hinge mechanism 300 is a second rotation axis. Optionally, the first rotation axis and the second rotation axis may be different from each other and perpendicular to each other, at this time, the rotation directions of the first hinge mechanism 300 and the second hinge mechanism 730 are different, that is, the folding directions of the first hinge mechanism 300 and the second hinge mechanism 730 are different, so that the frames of the first body part 710 and the second body part 720 form a relative structure, and the first temple 810 and the second temple 820 may be located on one side of the glasses body 700 after being folded. As such, the upper sides of the first and

second body parts

710 and 720 may be close to each other. Alternatively, the first and second rotation axes may be parallel, and in this case, the rotation directions of the first and

second hinge mechanisms

300 and 730 coincide, that is, the folding directions of the two coincide, so that the first and

second temples

810 and 820 may be located between the first and

second body parts

710 and 720 after being folded. As such, the inner sides of the first and

second body portions

710 and 720 may be close to each other. The embodiment of the present disclosure does not limit the specific folding manner of the smart glasses.

With the eyeglass body 700 in the extended state, at least a portion of the second hinge housing 731 is retractable into at least one of the first and

second body portions

710, 720. At least a portion of the structure of the second hinge housing 731 may be hidden in at least one of the first body 710 and the second body 720 to reduce the distance between the first body 710 and the second body 720, so that the distance between the first body 710 and the second body 720 can meet the wearing requirements of the user. The "glasses body 700 in the unfolded state" described herein refers to a state where the first body part 710 and the second body part 720 extend in substantially the same direction and are suitable for being worn by a user.

With the eyeglass body 700 in the folded state, at least a portion of the second hinge housing 731 may extend beyond at least one of the first and

second body portions

710, 720. At least a portion of the structure of the second hinge housing 731 is exposed to at least one of the first body 710 and the second body 720 to increase the distance between the first body 710 and the second body 720, so that there is enough space between the first body 710 and the second body 720 to accommodate the folding mechanism of the temple 800 or the rims of the first body 710 and the second body 720. The "eyeglass body 700 is in a folded state" described herein means that the first body part 710 and the second body part 720 are folded relatively, and the upper sides or the lower sides of the first body part 710 and the second body part 720 may be close to each other, or the inner sides or the outer sides of the first body part 710 and the second body part 720 may be close to each other, which is suitable for a user to receive smart glasses.

In one example, the second hinge housing 731 may include a first sub-housing 731a and a second sub-housing 731b, the first sub-housing 731a has a first avoiding hole 732, the second sub-housing 731b has a second avoiding hole 733, the second hinge mechanism 730 further includes a second connecting shaft 734, the first sub-housing 731a and the second sub-housing 731b each have an inner cavity, two ends of the second connecting shaft 734 are respectively inserted into the inner cavities of the first sub-housing 731a and the second sub-housing 731b, and the first sub-housing 731a and the second sub-housing 731b are respectively slidably engaged with the second connecting shaft 734. In this case, while the second connecting shaft 734 is slidably engaged with the first and second sub-housings 731a and 731b, the first and second sub-housings 731a and 731b are also rotatably engaged with the first and

second body portions

710 and 720, respectively, so that the distances between the first and

second body portions

710 and 720 and the second hinge mechanism 730 can be adjusted to accomplish the relative folding.

When the eyeglass body 700 is in the unfolded state, the first sub-housing 731a and the second sub-housing 731b are in sliding fit with the second connecting shaft 734, so that the first sub-housing 731a and the second sub-housing 731b are butted, and at least a part of the second connecting shaft 734 is accommodated in a space formed by the first sub-housing 731a and the second sub-housing 731b, and at this time, the distance between the first body part 710 and the second body part 720 is short.

When the eyeglass body 700 is in the folded state, the first sub-housing 731a and the second sub-housing 731b are both slid along the second connecting shaft 734 to move the first sub-housing 731a and the second sub-housing 731b away from each other, such that a portion of the second connecting shaft 734 is exposed between the first sub-housing 731a and the second sub-housing 731b, and at this time, the distance between the first body portion 710 and the second body portion 720 is longer.

Under the condition, the first connecting piece 7311a and the second connecting piece 7311b are in sliding fit with the third avoiding hole 734a to realize the sliding connection between the first sub-shell 731a and the second sub-shell 731b and the second connecting shaft 734, so that in the process of unfolding or folding the glasses body 700, the first connecting piece 7311a and the second connecting piece 7311b can form a sliding relation of limiting fit with the third avoiding hole 734a, thereby avoiding the situation that the smart glasses are in failure due to excessive sliding of the first sub-shell 731a and the second sub-shell 731b on the second connecting shaft 734, and further better ensuring the usability of the second hinge mechanism 730.

Optionally, a first end of the third avoiding hole 734a may be provided with a first limiting protrusion 7341a, a second end of the third avoiding hole 734a is provided with a second limiting protrusion 7341b, the first limiting protrusion 7341a and a space at an end of the third avoiding hole 734a form a first elastic positioning space, and the first connecting piece 7311a is in positioning fit with the first elastic positioning space; the second limiting protrusion 7341b and the other end space of the third avoiding hole 734a form a second elastic positioning space, and the second connecting member 7311b is matched with the second elastic positioning space in a positioning manner. In this case, the first and second limiting

protrusions

7341a and 7341b and the third avoiding hole 734a form a first elastic positioning space and a second elastic positioning space, respectively, so that the first and second connecting

members

7311a and 7311b can be positioned and matched with the first and second elastic positioning spaces, respectively, thereby improving the assemblability between the internal structures of the second hinge mechanism 730.

Optionally, a third limiting protrusion 7321 is disposed at an end of the first avoiding hole 732, which is close to the second sub-housing 731b, the third limiting protrusion 7321 and an end space of the first avoiding hole 732 form a third elastic positioning space, a fourth limiting protrusion 7331 is disposed at an end of the second avoiding hole 733, which is close to the first sub-housing 731a, the fourth limiting protrusion 7331 and an end space of the second avoiding hole 733 form a fourth elastic positioning space, in a folded state or an unfolded state, the first hinge shaft is positioned in the third elastic positioning space, and the second hinge shaft is positioned in the fourth elastic positioning space. In this case, the third and fourth limiting protrusions 7321 and 7322 form a third elastic positioning space and a fourth elastic positioning space with the first and second avoiding

holes

732 and 733, respectively, so that the first hinge shaft can be positioned in the third elastic positioning space and the second hinge shaft can be positioned in the fourth elastic positioning space when the glasses body 700 is in the folded state or the unfolded state, thereby realizing the positioning cooperation of the first and

second body parts
