As shown in fig. 1-3, the present application provides a magnetically attractable hinge mechanism. The magnetically attracted hinge mechanism comprises a first rotating member 1 and a second rotating member 3. The first rotor 1 is provided with a first magnetic part 2. The second rotating member 3 is provided with a second magnetic member 4. The second rotating member 3 is rotatably connected to the first rotating member 1. The first magnetic part 2 is fixedly arranged. The first magnetic part 2 may be fixed to the first rotating member 1 so as not to move relative to the first rotating member 1. The second magnetic part 4 is movably arranged. The second magnetic member 4 is movably provided on the second rotating member 3 and is movable with respect to the second rotating member 3. During the relative rotation of the first and second rotating members 1, 3, the first and second magnetic members 2, 4 remain magnetically engaged, including at least surface contact, to provide damping of the relative rotation of the first and second rotating members 1, 3.

The magnetic attraction type hinging mechanism is simple in structure and convenient to assemble, and magnetic attraction of the first magnetic component 2 and the second magnetic component 4 of the magnetic attraction type hinging mechanism at least comprises surface contact, so that damping effect provided by the first magnetic component and the second magnetic component can meet the requirement that the first rotating component 1 and the second rotating component 3 stay at a certain angle or any angle. The magnetic hinge mechanism has small size, can be suitable for scenes with small size like the rotating shaft of the glasses, and provides enough damping force.

The specific structural form of the first magnetic member 2 and the specific structural form of the second magnetic member 4 are not limited. As long as the first and second magnetic members 2 and 4 remain attracted at all times and have a surface contact state during the relative rotation of the first and second rotary members 1 and 3. Damping can be continuously provided for the first rotary member 1 and the second rotary member 3, and the damping provided in the state of surface contact can satisfy a predetermined requirement, for example, the damping at the time of suspension.

In some embodiments, the first magnetic component 2 and the second magnetic component 4 remain magnetically engaged by alternating face contact and line contact to provide varying damping. During the relative rotation of the first rotor 1 and the second rotor 3, the surface contact and the line contact of the first magnetic member 2 and the second magnetic member 4 are constantly alternated. The damping provided at the face contact is larger and the damping provided at the line contact is smaller. The method realizes the alternate appearance of large damping and small damping in the rotation process, so that the rotation force applied by overcoming the damping is different and has good rotation hand feeling. And the variable damping can meet the requirements of different damping. The damping provided by the surface contact at different positions during the relative rotation of the first rotating member 1 and the second rotating member 3 may be the same or different, and may be achieved by changing the contact area and/or the magnetic strength of the contact position. In addition, the alternating design of the surface and line contact has simple structure and easy realization.

In some embodiments, the first magnetic component 2 and the second magnetic component 4 remain magnetically engaged by alternating planar and curved contacts to provide varying damping. During the relative rotation of the first rotating member 1 and the second rotating member 3, the planar contact and the arcuate contact of the first magnetic member 2 and the second magnetic member 4 are constantly alternated. The damping that plane contact and cambered surface contact provided is all great, can satisfy the demand to the damping in the rotation in-process, and can make the relative rotation of first rotating member 1 and second rotating member 3 stay in a certain angle. It will be appreciated that the damping provided by the planar contact and the damping provided by the cambered contact may be different and may be achieved by varying the contact area and varying the magnetic strength of the different positions.

In some embodiments, the first magnetic component 2 and the second magnetic component 4 remain magnetically attracted by surface contact of different attraction areas to provide varying damping. The damping provided by the two magnetic parts is changed through the change of the adsorption area, so that good hand feeling in the rotation process is realized. And the damping provided by the surface contact is larger, so that the requirement on damping in the rotation process can be met, and the relative rotation of the first rotating piece 1 and the second rotating piece 3 can be stopped at a certain angle. For example, the attracting surfaces of the first magnetic member 2 and the second magnetic member 4 may be curved surfaces of different curvatures. Curved surfaces of different curvatures may form curved surfaces of different area sizes.

In some embodiments, the first magnetic component 2 may be a magnetic shaft. The second magnetic member 4 may be a magnetic body. The magnetic body includes an engaging surface 41. The magnetic shaft has a face that mates with the engaging face 41 to form a face contact. The magnetic shaft and the magnetic body are selected as magnetic components, so that the structure is simple, and the processing and the manufacturing are convenient. The design of the magnetic body with the engaging surface 41 facilitates surface contact to provide sufficient damping to meet rotational demands.

In some embodiments, the magnetic axis may be an optical axis or a polygonal axis. The attraction face 41 is a cambered surface or a plane surface that can form surface contact with the circumferential surface of the magnetic shaft. As shown in fig. 4 and 6, when the magnetic shaft is an optical axis, the circumferential surface of the magnetic shaft is a cambered surface. The engaging surface 41 is an arc surface that mates with the arc surface of the magnetic shaft. In this case, the engaging surface 41 is kept in surface contact with the circumferential surface of the magnetic shaft at all times, and can be rotated smoothly during rotation and can be held at any position during rotation. As shown in fig. 5 and 7, when the magnetic shaft is a polygonal shaft, the circumferential surface of the magnetic shaft is surrounded by a plurality of planes connected in sequence. A ridge line 21 is formed between two adjacent planes, and the attraction surface 41 of the magnetic body is a plane. During rotation, when the attraction face 41 contacts with the plane of the magnetic shaft, the attraction face 41 contacts with the plane. When rotated to the position of the engaging surface 41 and the ridge line 21 between the adjacent two planes (i.e., when the engaging surface 41 is shifted from contact with one plane to contact with the other plane, the ridge line 21 passes through the two planes), the engaging surface 41 makes line contact with the magnetic axis. Thus, alternating line contact and surface contact are realized to provide varying damping, so that the rotary motion has a feeling of jerk and can stay at a plurality of fixed positions.

In some embodiments, the magnetic shaft may be an optical axis, and the magnetic shaft is provided with a bump circumferentially distributed around the magnetic shaft. The engaging surface 41 includes an arc surface and a tilted portion at opposite ends of the arc surface. The cambered surface is matched with the peripheral surface of the magnetic shaft to form surface contact. The raised portion can guide the engaging surface 41 to rotate into surface contact with the convex surface of the bump. The protruding points are arranged on the magnetic shaft to form surface contact with different contact areas, so that different damping is provided, good rotating hand feeling is achieved, and the rotating position can be determined.

In some embodiments, the suction surface 41 may form multiple-sided contacts with the magnetic axis when the suction surface 41 is in surface contact with the magnetic axis. The magnetic axis is a polygonal axis. The engaging surface 41 includes a first surface portion and a second surface portion, and the engaging surface 41 can be simultaneously in surface contact with at least two surfaces of the magnetic shaft. The first face portion and the second face portion are non-coplanar and both may be planar so as to be in contact with the non-coplanar faces of the magnetic axis. The alternation of line contact and surface contact is realized in the rotation process, and changeable damping is provided, so that the rotary handle and the pause feeling are good.

In some embodiments, the magnetic shaft may be a contoured shaft, the perimeter of the contoured shaft comprising a continuous plurality of faces, the engaging face 41 being in face contact with at least one face of the contoured shaft. The continuous plurality of facets may include curved and planar facets and may also include irregularly shaped facets. The engaging surface 41 may include only one surface and may include a plurality of surfaces. When the suction surface 41 includes a plurality of surfaces, the plurality of surfaces may be the same plane, the same cambered surface, or both the plane and the cambered surface, and may also include a special-shaped surface. As long as it is ensured that the engaging surface 41 and the circumferential surface of the profiled shaft form a surface contact during rotation.

As can be seen from the description of the different embodiments above, the form of the surface contact is not limited. The contact may be one surface contact or a plurality of surfaces contact at the same time. When the plurality of surfaces are contacted simultaneously, the plurality of surfaces can be all planes or all cambered surfaces, and can also comprise both planes and cambered surfaces.

As shown in fig. 4 and 5, the magnetic shaft is provided with a first stopper 22. The first limiting member 22 is disposed along an axial direction of the magnetic shaft to limit the magnetic body in the axial direction of the magnetic shaft. The first limiting member 22 may include two limiting rings, which are disposed around the outer circumference of the magnetic shaft and spaced apart in the axial direction of the magnetic shaft, so as to define a region where the magnetic body magnetically engages with the magnetic shaft. The two limiting rings can limit the magnetic body from two opposite sides of the magnetic body, and prevent the magnetic body from moving in the axial direction of the magnetic shaft.

As shown in fig. 7 and 8, the magnetic shaft is provided with a second stopper 23. The second stopper 23 is disposed in the circumferential direction of the magnetic shaft to restrict the magnetic body in the circumferential direction of the magnetic shaft. The second stopper 23 may be two stoppers. The two stops may be located on the same cross section of the magnetic shaft. One of the stoppers is used for limiting the opening state of the two rotating members, and the other stopper is used for limiting the closing state of the two rotating members. With continued reference to fig. 7 and 8, fig. 7 illustrates one of the stops limiting the open state and fig. 8 illustrates the other stop limiting the closed state.

In some embodiments, the material of the first magnetic component 2 is ferromagnetic metal, magnetic plastic or magnetic rubber. The second magnetic part 4 is a magnet, a magnetic plastic or a magnetic rubber. As long as the first magnetic member 2 and the second magnetic member 4 can maintain magnetic attraction.

When the first magnetic member 2 is a magnetic shaft, the magnetic shaft may be a metal shaft, a magnetic plastic shaft, a magnetic rubber shaft, or the like. When the second magnetic member 4 is a magnetic member, as shown in fig. 2, the magnetic member may be a magnet block, a magnetic plastic block, a magnetic rubber block, or the like. The shape of the magnetic member is not limited to a block shape, and other shapes such as a bar shape and the like may be selected according to actual needs.

The magnetic member includes both a member capable of generating a magnetic field and a member capable of being magnetized by an external magnetic field, such as iron. At least one of the first magnetic member 2 and the second magnetic member 4 should be capable of generating a magnetic field, such as a magnet or the like.

The first magnetic part 2 may be fixed to the first rotating member 1 in various ways, for example by means of an adhesive, a connection, etc., such that the first magnetic part 2 is not movable. In some embodiments, as shown in fig. 1 and 2, a fixing seat 11 is provided on the first rotating member 1, and the first magnetic component 2 is fixed on the fixing seat 11. As shown in fig. 3, the second rotating member 3 is provided with a receiving groove 31. The second magnetic component 4 is disposed in the accommodating groove 31 and can move relative to the accommodating groove 31 to relatively enter and exit the accommodating groove 31, so that the second magnetic component 4 can always keep adsorbing with the first magnetic component 2 to provide damping for rotation in the process of relatively rotating the first rotating member 1 and the second rotating member 3. The second rotating member 3 is provided with a matching portion matching with the first stopper 22 for matching the second rotating member 3 with the outer shape of the first magnetic member 2 when the first rotating member 1 and the second rotating member 3 are rotated relatively.

The number of the second magnetic members 4 is not limited and may be one or more. When there are a plurality of the second rotating member 3, a plurality of the accommodating grooves 31 corresponding to the number of the second magnetic members 4 may be provided for accommodating the second magnetic members 4, respectively. With continued reference to fig. 3, this embodiment shows three receiving grooves 31, and the second magnetic members 4 may be respectively disposed in the three receiving grooves 31.

In some embodiments, in order to enable the second magnetic member 4 to maintain stable attraction with the first magnetic member 2, an elastic member may be provided in the accommodation groove 31. The elastic member acts on the second magnetic member 4 to apply a force to the second magnetic member 4 toward the first magnetic member 2 so that the second magnetic member 4 is held against the first magnetic member 2, and the two are continuously attracted without being separated. The specific structural form of the elastic member is not limited and can be selected according to actual needs. In this embodiment, the elastic member may be a spring, for example. One end of the spring may be connected to the bottom of the accommodating groove 31, and the other end of the spring is connected to the second magnetic member 4.

With continued reference to fig. 2, the magnetically attractable hinge mechanism further includes a shaft 5. The first rotating member 1 is hinged with the second rotating member 3 through a rotating shaft 5. The axis of the rotation shaft 5 is collinear with the rotation axis of the second magnetic member 4. By the design, the whole structure is compact, and the rotation is stable and smooth.

With continued reference to fig. 2, the fixing seat 11 is disposed in the middle of one side of the first rotating member 1, which is used for hinging with the second rotating member 3. The first magnetic part 2 is fixed to a fixed seat 11, see fig. 1. As shown in fig. 2 and 3, the second rotary member 3 has two first shaft holes 32 coaxially provided on the side where the first rotary member 1 is hinged. The receiving groove 31 is provided between the two first shaft holes 32 so that the second magnetic member 4 is centrally disposed at one side of the second rotary member 3. Two opposite sides of the fixed seat 11 are respectively provided with a second shaft hole 111, and two ends of the rotating shaft 5 are respectively assembled in the corresponding first shaft hole 32 and the second shaft hole 111. The rotational connection of the first rotational element 1 and the second rotational element 3 is achieved by means of a rotational shaft 5.

The specific structural forms of the first rotating member 1 and the second rotating member 3 are not limited, and can be determined according to the specific application scene of the magnetic hinging mechanism. For example, the first rotary member 1 may be plate-shaped as shown in fig. 1 and 2, and the second rotary member 3 may be flip-shaped as shown in fig. 1 to 3.

The magnetic type hinging mechanism adopts magnetic materials to provide damping, has wide adjustable range of shape, size and the like, and is convenient to adjust. Can be widely applied to any rotating structure requiring different damping. And the magnetizing strength of the magnetic material can be adjusted to meet different damping requirements. And the first magnetic part 2 and the second magnetic part 4 of the magnetic attraction type hinging mechanism are convenient to assemble, and jig equipment is not needed.

The application provides an intelligent glasses 400 simultaneously, intelligent glasses 400 includes picture frame 401 and mirror leg 402, and intelligent glasses 400 still includes the magnetism of any one of the above-mentioned embodiments and inhale formula hinge mechanism. The smart glasses 400 may be virtual reality glasses, augmented reality glasses, or mixed reality glasses. An optical module and a circuit board can be arranged in the glasses frame 401 of the intelligent glasses 400 to realize the display effect of virtual reality, augmented reality or mixed reality.

In some embodiments, the frame 401 forms the first rotational member 1 and the temple 402 forms the second rotational member 3, such that the temple 402 and the frame 401 form a hinge. Alternatively, the frame 401 is fixed to the first rotating member 1, the temple 402 is fixed to the second rotating member 3, and the temple 402 is hinged to the frame 401.

As shown in fig. 12 to 24, the present application also provides a pressure maintaining fixture for the smart glasses 400. The pressure maintaining jig comprises a base 100, an upper cover 200 and a gland 300. The upper surface of the base 100 is provided with a placement groove 101 for placing the smart glasses 400. The side of the frame 401 of the smart glasses 400 facing away from the human eye is provided with lenses 403. The side of the frame 401 facing the human eye is provided with a metal ring 405. The upper cover 200 has a through hole 201. The inner side surface of the upper cover 200 is provided with a pressing member 202. The pressing cover 300 is provided on the outer side surface of the upper cover 200. The pressing cover 300 can at least partially pass through the through hole 201 to correspond to the metal ring 405, so that when the upper cover 200 is pressed on the base 100, the pressing piece 202 presses against the lens frame 401 of the intelligent glasses 400, and the pressing cover 300 presses against the metal ring 405, so as to simultaneously maintain the pressure of the lens 403 and the metal ring 405. The dwell pressure on the lens 403 may be greater than the dwell pressure on the metal ring 405.

Referring to fig. 9-11, smart glasses 400 include a frame 401, a temple 402 (only a small portion of the temple 402 is shown connected to the frame 401), a lens 403, and a metal ring 405. The lens 403 is mounted on the side of the frame 401 facing away from the human eye, which is hereinafter defined as the outer side for convenience of description. The lenses 403 may be secured to the outside of the frame 401 using automated equipment or by hand bonding. The side of the mirror frame 401 facing the human eye is provided with a mounting groove 406, and a metal ring 405 is adhered in the mounting groove 406. The glue used for bonding must have a certain initial adhesion force, so that after the bonding, the situation that the smart glasses 400 move or fall off relative to the glasses frame 401 cannot occur in the process of stably moving the smart glasses 400 can be ensured.

The pressure maintaining jig can maintain pressure of the lenses 403 and the metal rings 405 of the intelligent glasses 400 through the upper cover 200 and the gland 300, does not need to maintain pressure respectively, simplifies pressure maintaining operation, and improves operation efficiency.

In some embodiments, the pressure provided to the lens 403 when the upper cover 200 is pressed onto the base 100 is different from the pressure provided to the metal ring 405. Through one-time operation, not only can carry out the pressurize to lens 403 and metal ring 405 simultaneously, can also satisfy the different pressurize pressure demands of lens 403 and metal ring 405, promote the yields of product.

It should be noted that, the upper cover 200 and the base 100 may be a split structure, and there is no connection therebetween. The upper cover 200 and the base 100 may be hinged, so that the upper cover 200 can rotate relative to the base 100, and the upper cover 200 is pressed onto the base 100 conveniently.

In some embodiments, as shown in fig. 15 and 16, the placement slot 101 has a mating surface 102 that mates with a lens periphery 404 of the smart glasses 400. As shown in fig. 15 and 16, when the upper cover 200 is pressed onto the base 100, the pressing member 202 presses against the frame 401 of the smart glasses 400, so that the lens periphery 404 is tightly adhered to the mating surface 102 of the placement groove 101 (the lens periphery 404 can be seen in fig. 16), and the pressure of the lens 403 is maintained. By designing the mating surface 102 that fits the lens periphery 404 in the placement groove 101, the entire dispensing periphery of the lens 403 can be completely fitted to the mating surface 102. When the upper cover 200 is pressed onto the base 100, the force acting on the mirror frame 401 can act against the dispensing periphery of the lens 403 through the matching surface 102, so that the pressure maintaining effect is uniform at all positions of the lens periphery 404.

As shown in fig. 12 to 13, the pressing members 202 are disposed corresponding to opposite sides of the lens 403 of the smart glasses 400, respectively. The pressing member 202 has a stopper surface for pressing in contact with the lens frame 401. The pressing members 202 are provided on opposite sides of the lens 403, so that the effect of the pressing members 202 on the lens frame 401 can be improved, and the force applied to the lens frame 401 can be relatively balanced. The limiting surface is arranged, so that the pressing piece 202 and the mirror frame 401 can be ensured to be stably contacted and pressed, the lens periphery 404 and the matching surface 102 are tightly attached, and pressure maintaining is realized. It should be noted that, the opposite sides of the lens 403 may be the upper side and the lower side of the intelligent glasses 400 in the wearing state, and the lengths of the upper side and the lower side are longer than the lengths of the left side and the right side of the intelligent glasses 400, so that the acting area of the pressing member 202 and the lens frame 401 can be increased, the pressing effect is improved, and then the pressure maintaining effect is improved.

In some embodiments, a buffer layer may be disposed on the surface of the limiting surface to prevent the smart glasses 400 from being damaged when the upper cover 200 is quickly pressed onto the base 100. The buffer layer can be made of sponge. The thickness of the buffer layer can be selectively determined according to the requirement. For example, the thickness of the buffer layer is 0.5mm to 2mm, preferably 1mm.

In some embodiments, as shown in fig. 13, the upper surface of the base 100 is provided with a first magnetic member 103, and the upper cover 200 is provided with a second magnetic member 203. When the upper cover 200 is pressed onto the base 100, the upper cover 200 drives the pressing member 202 to press against the mirror frame 401 through magnetic attraction. The force of the limiting surface acting on the lens frame 401 is derived from the attractive force of the first magnetic piece 103 and the second magnetic piece 203, so as to maintain the pressure of the lens 403.

The shape, the number, and the setting positions of the first magnetic member 103 and the second magnetic member 203 are not particularly limited, and may be selected and determined according to the holding pressure actually required. For example, the first magnetic member 103 and the second magnetic member 203 are each plural and are disposed around the placement slot 101 to apply a uniform force to the lens 403. When the upper cover 200 and the base 100 are rotatably coupled, the plurality of first magnetic members 103 may be disposed on the base 100 near a side of the base 100 not hinged to the upper cover 200.
