With the development of head-mounted display devices (such as smart glasses), the requirements of users on wearing comfort thereof are becoming more and more evident. In the prior art, in order to make the great user of head form can wear, can make intelligent glasses take place deformation generally to make the mirror leg turn up for the picture frame relatively, so, have great space between two mirror legs and supply the great user of head form to wear, however the head form is bigger, and the degree that the mirror leg turned up for the picture frame relatively is bigger, then the clamping force of two mirror legs to the head is bigger, makes intelligent glasses wear the travelling comfort and reduces. Therefore, the invention provides a hinge module, which aims to reduce the variation trend of the clamping force of the glasses legs to the head of a user in the process of turning the glasses legs outwards relative to the glasses frame.

Referring to fig. 1-14, in one embodiment of the present invention, the hinge module 200 is applied to a device that requires a rotational connection of two components, and the hinge module 200 is described herein by taking the smart glasses 100 in a head-mounted display device as an example. The hinge module 200 includes a first bracket 210 and a second bracket 220. One of the first bracket 210 and the second bracket 220 is used for connecting the lens frame 110, the other is used for connecting the lens leg 140, and the second bracket 220 is rotatably connected with the first bracket 210. In this way, the frame 110 and the temple 140 of the smart glasses 100 can be rotated relatively by the first bracket 210 and the second bracket 220. It should be noted that the first bracket 210 and the second bracket 220 may have a connection relationship of direct rotation connection, or indirect rotation may be achieved by other components. The hinge module 200 has an open state in which the temple 140 is opened with respect to the mirror frame 110, and an everted state in which the temple 140 is everted with respect to the mirror frame 110. It can be appreciated that when the hinge module 200 is in the open state and the everted state, the smart glasses 100 are in a wearing state for wearing by a user. When the user wears the hinge module 200, the hinge module 200 is opened for a proper head shape, and the hinge module 200 is turned outside for a larger head shape, and the hinge module 200 further includes a first runner 330, a second runner 400, an elastic member 310, a first movable member 340, and a second movable member 360. The first rotating wheel 330 and the second rotating wheel 400 both rotate along with the second bracket 220, the elastic member 310 is disposed between the first rotating wheel 330 and the second rotating wheel 400, the first movable member 340 is disposed between the first rotating wheel 330 and the elastic member 310, and the second movable member 360 is disposed between the second rotating wheel 400 and the elastic member 310. The direction from the first movable member 340 toward the second movable member 360 is a first direction. The greater the everting angle of the temple 140, the greater the moving distance of the first movable member 340 along the first direction under the driving action of the first rotating wheel 330, and the greater the moving distance of the second movable member 360 along the first direction under the driving action of the second rotating wheel 400, so that the compression amount of the elastic member 310 tends to be constant during the everting of the temple 140, and the tendency of the hinge module 200 to return toward the opened state tends to be constant. In this way, the first movable member 340 and the second movable member 360 jointly control the compression amount of the elastic member 310, the first movable member 340 is used for compressing the elastic member 310, the second movable member 360 is used for extending the elastic member 310 so as to reduce the compression amount of the elastic member 310, so that the trend of weakening the hinge module 200 to be reset to the open state is realized, and the value of the clamping force to the user is ensured to be greater than zero, so that the user can wear the smart glasses 100 more stably. Therefore, the clamping force suffered by the user with the larger head shape when wearing the intelligent glasses 100 and the clamping force suffered by the user with the proper head shape when wearing the intelligent glasses 100 are not greatly different, and the wearing comfort of the intelligent glasses 100 is improved.

It should be noted that the number of the first rotating wheel 330, the second rotating wheel 400, the elastic member 310, the first movable member 340, and the second movable member 360 can be set according to practical requirements.

Optionally, in an embodiment, the first rotating wheel 330 is provided with a first protrusion 334 near one side of the first movable member 340, the first movable member 340 is provided with a first pushing surface 350 for sliding the first protrusion 334, the first pushing surface 350 is provided with a first guiding surface 352, during the process of returning from the everted state to the open state, the rotation direction of the second support 220 relative to the first support 210 is a second direction, in the second direction, the first guiding surface 352 is obliquely arranged towards the first direction, one side of the second rotating wheel 400 near the second movable member 360 is provided with a second protrusion 410, the second movable member 360 is provided with a second pushing surface 370 for sliding the second protrusion 410, the second pushing surface 370 is provided with a fifth guiding surface 371, and in the second direction, the fifth guiding surface 371 is obliquely arranged towards the first direction. During the eversion of the temple 140, the first protrusion 334 slides against the first guiding surface 352 to move the first movable member 340 in the first direction, and the second protrusion 410 slides against the fifth guiding surface 371 to move the second movable member 360 in the first direction. In this way, the first movable member 340 and the second movable member 360 jointly control the compression amount of the elastic member 310, the first movable member 340 is used for compressing the elastic member 310, the second movable member 360 is used for extending the elastic member 310 so as to reduce the compression amount of the elastic member 310, so that the trend of weakening the hinge module 200 to be reset to the open state is realized, and the value of the clamping force to the user is ensured to be greater than zero, so that the user can wear the smart glasses 100 more stably. Therefore, the clamping force suffered by the user with the larger head shape when wearing the intelligent glasses 100 and the clamping force suffered by the user with the proper head shape when wearing the intelligent glasses 100 are not greatly different, and the wearing comfort of the intelligent glasses 100 is improved.

Specifically, during the process of wearing the smart glasses 100 by a user with a larger head shape, the user turns the glasses leg 140 outwards relative to the glasses frame 110, so that the first bracket 210 and the second bracket 220 rotate relatively, so that the first rotating wheel 330 rotates relative to the first movable member 340, and the second rotating wheel 400 rotates relative to the second movable member 360, so that during the process of returning from the open state to the outwards turned state, the first protrusion 334 slides on the first guiding surface 352 to move the first movable member 340 along the first direction, so that the elastic member 310 is compressed, the compressed elastic member 310 has elastic potential energy, the second protrusion 410 slides on the fifth guiding surface 371 to move the second movable member 360 along the first direction, so that the elastic member 310 is elongated, that is, the compression degree of the elastic member 310 is reduced, and it is required to point out that, under the action of the elastic member 310, the hinge module 200 has a tendency to return from the outwards turned state to the open state, so that the clamping force is generated by the glasses leg 140 to the user. When the user takes down the smart glasses 100, the elastic member 310 releases elastic potential energy to stretch to push the first movable member 340, and the first rotating wheel 330 drives the glasses leg 140 to rotate under the cooperation of the first guiding surface 352 and the first protrusion 334, so that the hinge module 200 is turned from the everted state to the opened state, so that the hinge module 200 enters the opened state, and at the same time, the second movable member 360 approaches the first rotating wheel 330 along the stretching direction of the elastic member 310 to prepare for the hinge module 200 to enter the everted state next time.

However, the present design is not limited thereto, in other embodiments, the matching structure of the first rotating wheel 330 and the first movable member 340 may be other structures, and the matching structure of the second rotating wheel 400 and the second movable member 360 may be other structures, so long as the larger the everting angle is, the larger the moving distance of the first movable member 340 along the first direction under the driving action of the first rotating wheel 330 is, the larger the moving distance of the second movable member 360 along the first direction under the driving action of the second rotating wheel 400 is, so that the compression amount of the elastic member 310 tends to be constant during the everting process of the temple 140, and the tendency of the hinge module 200 to return towards the open state tends to be constant.

Optionally, in an embodiment, the first rotating wheel 330 and the second bracket 220 are separate components, and the first rotating wheel 330 and the second bracket 220 may be connected together by assembling, so that when the first rotating wheel 330 is damaged, the first rotating wheel 330 may be replaced separately, which is beneficial to reducing the degree of repairing the hinge module 200. However, the present design is not limited thereto, and in other embodiments, the first rotating wheel 330 and the second bracket 220 are integrally formed, so that the assembling process of the hinge module 200 can be reduced, and the assembling efficiency of the hinge module 200 can be improved.

Optionally, in an embodiment, the second rotating wheel 400 and the second bracket 220 are separate components, and the second rotating wheel 400 and the second bracket 220 may be connected together by assembling, so that when the second rotating wheel 400 is damaged, the second rotating wheel 400 may be replaced separately, which is beneficial to reducing the degree of repairing the hinge module 200. However, the present design is not limited thereto, and in other embodiments, the second rotating wheel 400 and the second bracket 220 are integrally formed, so that the assembling process of the hinge module 200 can be reduced, and the assembling efficiency of the hinge module 200 can be improved.

Alternatively, in an embodiment, in the second direction, the first abutment surface 350 is provided with a second guide surface 353 provided downstream of the first guide surface 352, the first guide surface 352 and the second guide surface 353 intersect and define a first valley 351, and in the depth direction of the first valley 351, the distance between the first guide surface 352 and the second guide surface 353 gradually decreases, and when the first protrusion 334 abuts the first guide surface 352 and the second guide surface 353, the hinge module 200 is in an open state and has a tendency to be maintained in the open state. Thus, the first valleys 351 are substantially V-shaped groove structures. As such, when the first protrusion 334 abuts the first guide surface 352 and the second guide surface 353, the hinge module 200 has a tendency to remain in an open state. Thus, when the hinge module 200 is in the open state, the temple 140 will not swing left and right easily, which is beneficial to improving the experience of the user for wearing the smart glasses 100. It should be noted that either one of the first guide surface 352 and the second guide surface 353 may be a plane surface or a curved surface, which is not limited herein. The first guide surface 352 and the second guide surface 353 may be disposed symmetrically or asymmetrically with respect to each other, and are not limited thereto.

Optionally, in an embodiment, in the second direction, the first abutment surface 350 is provided with a first damping surface 354 arranged downstream of the second guiding surface 353, the first damping surface 354 intersecting the second guiding surface 353, and the first protrusion 334 has a tendency to stay on the first damping surface 354 when the first protrusion 334 abuts against the first damping surface 354. It can be appreciated that the hinge module 200 has a folded state in which the temple 140 is folded relative to the frame 110, so that the hinge module 200 is reset from the unfolded state to the folded state, the first damping surface 354 provides a stay position for the first protrusion 334, so that the first support 210 and the second support 220 can form a plurality of stable included angles, that is, the temple 140 and the frame 110 can form a plurality of stable included angles, which enriches the choices of the user and improves the control feeling of the user on the smart glasses 100. The glasses legs 140 and the glasses frames 110 are provided with a plurality of stable included angles, which is beneficial to the modeling of the smart glasses 100 for the user to concave, and when the user does not wear the smart glasses 100, the space around the smart glasses 100 can be decorated. In addition, the first damping surface 354 provides a certain resistance to the sliding of the first protrusion 334, giving the user a sense of high grade. It should be noted that the first damping surface 354 may be perpendicular to the first direction, or may be disposed at an acute angle to the first direction, as long as the first damping surface 354 provides the first protrusion 334 with resistance to stay on the first damping surface 354.

To avoid excessive resistance to sliding of the first protrusion 334 against the first damping surface 354, to facilitate rotation of the temple 140 by the user, optionally, in one embodiment, the first damping surface 354 is located between the highest and lowest points of the first guiding surface 352 in the valley depth direction of the first valley 351. Of course, in other embodiments, if it is considered that the temple 140 is driven by a certain external force, the temple 140 will not easily rotate, and then the first damping surface 354 may be higher than the highest position of the first guiding surface 352 in the valley depth direction of the first valley 351, so that a larger pressure is generated between the first protrusion 334 and the first damping surface 354, so that the first damping surface 354 can provide a larger resistance to the first protrusion 334.

Optionally, in an embodiment, the hinge module 200 has a folded state in which the temple 140 is folded relative to the frame 110, in the second direction, the first pushing surface 350 is further provided with a third guiding surface 356 disposed downstream of the first damping surface 354, and a fourth guiding surface 357 disposed downstream of the third guiding surface 356, the third guiding surface 356 and the fourth guiding surface 357 intersect and limit the second valley 355, and in the depth direction of the second valley 355, the distance between the third guiding surface 356 and the fourth guiding surface 357 gradually decreases, and when the first protrusion 334 abuts against the third guiding surface 356 and the fourth guiding surface 357, the hinge module 200 is in the folded state and has a tendency to maintain the folded state. Thus, the second valleys 355 are generally V-shaped groove structures. As such, when the first protrusion 334 abuts the third guide surface 356 and the fourth guide surface 357, the hinge module 200 has a tendency to remain in the folded state. Thus, when the hinge module 200 is in the folded state, the temple 140 cannot easily shake left and right, which is beneficial to improving the experience of the user for wearing the smart glasses 100. It should be noted that any one of the third guide surface 356 and the fourth guide surface 357 may be a plane surface or a curved surface, which is not limited herein. The third guide surface 356 and the fourth guide surface 357 may be disposed symmetrically or asymmetrically with respect to each other, and are not limited thereto.
