As shown in fig. 1-3, the present application provides a magnetically-attractable hinge mechanism. The magnetically-attracted hinge mechanism includes a first rotating member 1 and a second rotating member 3. The first rotating member 1 is provided with a first magnetic member 2. The second rotating member 3 is provided with a second magnetic element 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 be movable relative to the first rotating member 1. The second magnetic means 4 are movably arranged. The second magnetic part 4 can be movably arranged on the second rotating part 3 and can move relative to the second rotating part 3. During the relative rotation of the first rotating member 1 and the second rotating member 3, the first magnetic part 2 and the second magnetic part 4 maintain magnetic attraction including at least surface contact to provide damping for the relative rotation of the first rotating member 1 and the second rotating member 3.

The utility model provides a formula hinge mechanisms is inhaled to magnetism simple structure, convenient assembling, and the magnetism of the first magnetic part 2 of formula hinge mechanisms and second magnetic part 4 is inhaled and is closed including the face contact at least, consequently, the damping effect that both provided can satisfy the requirement that first rotation piece 1 and second rotation piece 3 stopped at a certain angle or arbitrary angle. The magnetic-type hinge mechanism is small in size, can be adapted to a scene with small size like a 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 magnetic part 2 and the second magnetic part 4 are always kept attracted and have a surface contact state in the relative rotation process of the first rotating member 1 and the second rotating member 3. The first rotating member 1 and the second rotating member 3 can be constantly provided with damping, and the damping provided in the surface-contact state 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 maintain magnetic attraction through alternating surface contact and line contact to provide varying damping. During the relative rotation of the first rotating member 1 and the second rotating member 3, the surface contact and the line contact of the first magnetic part 2 and the second magnetic part 4 are continuously alternated. The damping provided is greater for surface contact and less for line contact. The alternating appearance of large damping and small damping in the rotating process is realized, and the rotating force applied by overcoming the damping has good rotating hand feeling. And the variable damping can meet the requirements for different damping. During the relative rotation of the first rotating member 1 and the second rotating member 3, the damping provided by the surface contact at different positions may be the same or different, and may be realized by changing the contact area and/or the magnetic strength of the contact position. In addition, the alternate design of surface contact and line contact has simple structure and easy realization.

In some embodiments, the first magnetic component 2 and the second magnetic component 4 maintain magnetic attraction by alternating planar and curved surface contacts to provide varying damping. During the relative rotation of the first rotating member 1 and the second rotating member 3, the plane contact and the arc contact of the first magnetic part 2 and the second magnetic part 4 are continuously alternated. The damping that plane contact and cambered surface contact provided is all great, can satisfy and rotate the in-process to the demand of damping, and can make first rotation piece 1 and second rotate the relative rotation of 3 and stop at a certain angle. It will be appreciated that the damping provided by the planar contact and the cambered contact may be different, and may be achieved by varying the contact area and varying the strength of the magnetic properties at different locations.

In some embodiments, the first magnetic component 2 and the second magnetic component 4 maintain magnetic attraction through surface contact of different attraction areas to provide varying damping. Through the change of the adsorption area, the damping provided by the two magnetic parts is changed, so that good hand feeling in the rotating process is realized. And the damping that the face contact provided is great, can satisfy the demand to the damping in the rotation process, and can make the relative rotation of first rotating member 1 and second rotating member 3 stop 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 having different curvatures. The curved surfaces with different curvatures can form curved surfaces with 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 a suction surface 41. The magnetic shaft has a face that mates with the attraction face 41 to form a face contact. The magnetic shaft and the magnetic body are selected as the magnetic parts, so that the structure is simple, and the processing and the manufacturing are convenient. The magnetic body is provided with an attraction surface 41 which is convenient for realizing surface contact so as to provide enough damping and meet the rotation requirement.

In some embodiments, the magnetic axis may be an optical axis or a polygonal axis. The attracting surface 41 is a curved surface or a flat surface that can come into 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 curved surface. The attracting surface 41 is an arc surface that is fitted with the arc surface of the magnetic shaft. In this case, the attracting surface 41 is always kept in surface contact with the circumferential surface of the magnetic shaft, and can smoothly rotate during rotation and stay 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 defined by a plurality of planes connected in sequence. The ridge 21 is formed between two adjacent planes, and the attracting surface 41 of the magnetic body is a plane. During the rotation, when the attraction surface 41 contacts with the plane of the magnetic shaft, the two contact with each other. When the attraction surface 41 is rotated to the position of the ridge 21 between the two adjacent planes (i.e., when the attraction surface 41 is switched from contact with one plane to contact with the other plane, it passes through the ridge 21 of the two planes), the attraction surface 41 and the magnetic axis form a line contact. Thus, alternate line contact and surface contact are realized to provide variable damping, so that the rotary motor has pause feeling during rotation and can stay at a plurality of fixed positions.

In some embodiments, the magnetic shaft may be an optical shaft with the salient points disposed circumferentially around the magnetic shaft. The suction surface 41 includes an arc surface and raised portions at opposite ends of the arc surface. The cambered surface is matched with the circumferential surface of the magnetic shaft to form surface contact. The raised portion can guide the suction surface 41 to rotate to form surface contact with the convex surface of the convex point. The salient points are arranged on the magnetic shaft to form surface contact with different contact areas, so that different damping is provided, the rotating handle has good rotating hand feeling, and the rotating position can be determined.

In some embodiments, the attracting and neutralizing surface 41 may form a multi-sided contact with the magnetic shaft when the attracting and neutralizing surface 41 forms a sided contact with the magnetic shaft. The magnetic axis is a polygonal axis. The attraction surface 41 includes a first surface portion and a second surface portion, and the attraction surface 41 is capable of making surface contact with at least two surfaces of the magnetic shaft at the same time. The first and second face portions are not coplanar and may both be planar so as to contact two non-coplanar faces of the magnetic axis. The alternating of line contact and surface contact is realized in the rotating process, variable damping is provided, and the rotating mechanism has good rotating hand feeling and pause feeling.

In some embodiments, the magnetic shaft may be a profiled shaft, the circumferential surface of the profiled shaft comprising a continuous plurality of faces, the attraction face 41 being in face contact with at least one face of the profiled shaft. The continuous plurality of faces may include curved faces and flat faces, and may also include irregular faces. The engaging surface 41 may include only one surface, and may include a plurality of surfaces. The suction surface 41 includes a plurality of surfaces, which may be the same plane, the same arc surface, or both the plane and the arc surface, and may also include a special-shaped surface. It is only necessary to ensure that the suction surface 41 and the peripheral surface of the special-shaped shaft are in surface contact during the rotation.

As can be seen from the above description of the various embodiments, the form of the surface contact is not limited. The contact may be made by one surface or by a plurality of surfaces simultaneously. When the multiple surfaces are contacted simultaneously, the multiple surfaces can be flat surfaces or arc surfaces, and can also comprise both flat surfaces and arc surfaces.

As shown in fig. 4 and 5, the magnetic shaft is provided with a first stopper 22. The first stoppers 22 are arranged along the axial direction of the magnetic shaft to limit the magnetic body in the axial direction of the magnetic shaft. The first position-limiting member 22 may include two position-limiting rings, which are disposed around the periphery of the magnetic shaft and spaced apart from each other in the axial direction of the magnetic shaft to define a magnetic body and a magnetic attraction region of the magnetic shaft. The two limit rings can limit the magnetic body from two opposite sides of the magnetic body, and the magnetic body is prevented from moving in the axial direction of the magnetic shaft.

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

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

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 strip shape, can 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, for example, iron. At least one of the first magnetic part 2 and the second magnetic part 4 should be capable of generating a magnetic field, such as a magnet or the like.

The first magnetic member 2 can be fixed to the first rotating member 1 in various ways, for example, by bonding, connecting, etc., so that the first magnetic member 2 cannot move. In some embodiments, as shown in fig. 1 and fig. 2, the first rotating member 1 is provided with a fixing seat 11, and the first magnetic member 2 is fixed on the fixing seat 11. As shown in fig. 3, the second rotating member 3 is provided with an accommodating groove 31. The second magnetic member 4 is disposed in the receiving groove 31 and is movable relative to the receiving groove 31 to enter and exit the receiving groove 31, so that the second magnetic member 4 can always keep adsorbing with the first magnetic member 2 during the relative rotation of the first rotating member 1 and the second rotating member 3, thereby providing damping for the rotation. The second rotating member 3 is provided with a matching portion matching with the first limiting member 22, and the matching portion is used for matching the outer shape of the second rotating member 3 with the outer shape of the first magnetic component 2 when the first rotating member 1 and the second rotating member 3 rotate 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 magnetic parts 4, a plurality of receiving grooves 31 corresponding to the number of the second magnetic parts 4 may be disposed on the second rotating member 3 for respectively receiving the second magnetic parts 4. With continued reference to fig. 3, the present 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 keep the second magnetic member 4 and the first magnetic member 2 stably attracted, an elastic member may be disposed in the accommodating groove 31. The elastic member acts on the second magnetic member 4, and is configured to apply an acting force to the second magnetic member 4 toward the first magnetic member 2, so that the second magnetic member 4 is kept abutting 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 receiving 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 rotating shaft 5 is collinear with the axis of rotation of the second magnetic member 4. By the design, the whole structure is compact, and the rotation is stable and smooth.

With continuing reference to fig. 2, the fixing base 11 is disposed in the middle of one side of the first rotating member 1 for being hinged to the second rotating member 3. The first magnetic part 2 is fixed to a holder 11, see fig. 1. As shown in fig. 2 and 3, the side of the second rotating member 3 hinged to the first rotating member 1 has two first shaft holes 32 coaxially provided. The receiving groove 31 is disposed between the two first shaft holes 32, so that the second magnetic member 4 is disposed at the center of one side of the second rotating member 3. Two sides of the fixed seat 11 deviating from each other 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 rotary connection of the first rotary part 1 and the second rotary part 3 is realized by means of a rotary shaft 5.

The specific structural forms of the first rotating member 1 and the second rotating member 3 are not limited, and may be determined according to the scene selection of the specific application of the magnetic hinge mechanism. For example, the first rotating member 1 may have a plate shape as shown in fig. 1 and 2, and the second rotating member 3 may have a flip shape as shown in fig. 1 to 3.

The damping device can be widely applied to any rotating structure needing different damping. And different damping requirements can be met by adjusting the magnetizing strength of the magnetic material. And the first magnetic part 2 and the second magnetic part 4 of the magnetic-type hinge mechanism are convenient to assemble without the help of jig equipment.

In some embodiments, the frame 401 forms a first rotatable member 1 and the temple 402 forms a second rotatable member 3, such that the temple 402 and the frame 401 form a hinge. Alternatively, the frame 401 is fixed to the first rotor 1, the temple 402 is fixed to the second rotor 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 jig for smart glasses 400. The pressure maintaining jig includes a base 100, an upper cover 200, and a pressing cover 300. The upper surface of the base 100 is provided with a placing groove 101 for placing the smart glasses 400. The side of the frame 401 of the smart glasses 400, which faces away from the eyes, is provided with a lens 403. The side of the frame 401 facing the eyes 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. At least part of the pressing cover 300 can 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 member 202 presses against the frame 401 of the smart glasses 400, and the pressing cover 300 presses against the metal ring 405, so as to simultaneously maintain pressure on the lens 403 and the metal ring 405. The dwell pressure for the lens 403 may be greater than the dwell pressure for the metal ring 405.

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

It should be noted that the upper cover 200 and the base 100 can be in a split structure, and they are not connected. The upper cover 200 and the base 100 can be hinged to enable the upper cover 200 to rotate relative to the base 100, so as to facilitate the pressing of the upper cover 200 on the base 100.

In some embodiments, as shown in fig. 15 and 16, the placement channel 101 has a mating surface 102 that mates with the lens periphery 404 of the smart eyewear 400. As shown in fig. 15 and 16, when the top 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 attached to the mating surface 102 of the placement groove 101 (the lens periphery 404 can be seen in fig. 16), and the pressure is maintained on the lens 403. By designing the mating surface 102 in the placement groove 101 to fit the lens periphery 404, the entire dispensed periphery of the lens 403 can be completely fit to the mating surface 102. When the cover 200 is pressed onto the base 100, the force acting on the frame 401 can react to the dispensing periphery of the lens 403 through the mating surface 102, so that the pressure maintaining effect at all positions of the lens periphery 404 is consistent.

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

In some embodiments, the surface of the limiting surface may be provided with a buffer layer to prevent the smart glasses 400 from being damaged when the upper cover 200 is quickly pressed on the base 100. The buffer layer can be made of sponge. The thickness of the buffer layer can be selected and determined as required. For example, the buffer layer has a thickness of 0.5mm to 2mm, preferably 1 mm.

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

The shape, number, and arrangement position 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 actual required holding pressure. For example, the first magnetic member 103 and the second magnetic member 203 are each provided in plurality and arranged around the housing groove 101 to apply a uniform force to the lens 403.
