Description

Hinge structure and AR glasses

Technical Field

The invention belongs to the technical field of AR (augmented reality) glasses, and particularly relates to a hinge structure and AR glasses.

Background

The current AR products are designed into a glasses shape more and more for the purpose of being wearable and used; in order to guarantee the reliability of products, often the temple part can not be folded, so that the risk of damaging an internal signal line caused by folding of the temple is avoided, but the structural design is poor in storage experience, and even if some products have foldable functions of the temple, the signal line is often exposed outside, so that the attractiveness of the product is seriously influenced. Even the mirror leg can be buckled still only possesses the function of buckling, and the size is all great relatively, and the weight of pivot is heavier, the complicated cost of manufacture of structural design is high, and user experience is poor.

In addition, because the head types of the users are different greatly, the AR glasses on the market at present cannot be well adapted to the wearing of various head types, and certain clamping force is ensured, so that the wearing experience of the users is not very comfortable.

In order to improve user experience, AR products have more and more functions, more and more complex hardware, higher and more power consumption of the whole machine, and higher and more requirements on heat dissipation of the whole machine; the glasses form has narrow internal space, hardware is fully distributed on the glasses frame side and the glasses leg side, a plurality of signal wires are required to connect the hardware on the glasses frame side and the glasses leg side through a rotating shaft, meanwhile, the heating value of each hardware is large, and the heat source distribution is not uniform, so that the rotating shaft is required to have reliable threading function and good heat conduction and heat transfer capacity, and the signal wires and the heat conduction and heat transfer performance are not influenced by the fact that the rotating shaft is bent for many times.

11121 and 1312 are in contact with each other in a staggered manner (at this time, the inclined plane ends 134 of the second and fourth engaging

portions

12121 and 1313 are also in contact with each other in a staggered manner), so that the first direction of the first rotating member 111 and the second direction of the second rotating member 121 form an angle larger than the obtuse angle in the natural state, and the included angle may be an obtuse angle, a straight angle or a major angle, which is suitable for a person with a large brain size. As shown in fig. 13 and 14, when the hinge structure 10 extends inward from the natural state, the slant ends 134 of the first engagement portion 11121 and the third engagement portion 1312 are in staggered contact (at this time, the slant ends 134 of the second engagement portion 12121 and the fourth engagement portion 1313 are also in staggered contact), and the first direction constituting the first rotating member 111 and the second direction constituting the second rotating member 121 form an angle smaller than the obtuse angle in the natural state, and the angle may be an obtuse angle, a right angle, or an acute angle, which is suitable for the folding operation of the temple 20.

Specifically, in the present embodiment, the fit between the first rotating portion 1112 and the first fixing portion 142, the fit between the second rotating portion 1113 and the second fixing portion 143, the fit between the third rotating portion 1212 and the first fixing portion 142, and the fit between the fourth rotating portion 1213 and the second fixing portion 143 are all zero fit or interference fit, and depending on the magnitude of interference between each other, friction force and further damping force can be provided when the hinge structure 10 rotates, and different damping forces can be realized by adjusting the magnitude of the interference, so that the use feeling and the quality of the product can be greatly improved.

Specifically, in the present embodiment, the first rotating member 111 and the lens frame 30, and the second rotating member 121 and the temple 20 are connected and fixed through the matching of the positioning column and the positioning hole (or the screw column and the screw hole).

Specifically, the parts can be manufactured through an MIM mold and a simple stamping mold, the number of the parts is small, the assembly is simple and difficult, the processing and manufacturing cost and difficulty are greatly reduced, and the parts are connected into a whole through a fixing shaft, so that the device is simple and convenient. Meanwhile, through interference assembly between the rotating part and the base 14, friction force can be generated during rotation, and further damping force is provided, so that the hinge assembly has a damping effect.

Further, as shown in fig. 9-15, when the hinge structure 10, the temple 20 and the eyeglass frame 30 are assembled and are in a natural state, the two rotation members have a certain inner angle (i.e. an obtuse angle is formed between the first direction of the first rotation member 11 and the second direction of the second rotation member 12), and at this time, the first engagement portion 11121 of the first rotation member 111 and the third engagement portion 1312 of the preload member 131 are in full contact, and the second engagement portion 12121 of the second rotation member 121 and the fourth engagement portion 1313 of the preload member 131 are in full contact. When the hinge structure 10 is unfolded outwards, the inclined plane end 134 of the matching part of the rotating part can press the inclined plane end 134 of the matching part of the pre-tightening part 131, the pre-tightening part 131 is forced to move downwards to press the disc spring, the disc spring can generate a rebound force at the moment, the reverse elasticity can force the rotating part to bend inwards, when the user wears the glasses, the trend that the glasses legs 20 bend inwards is reflected, therefore, a clamping force of the glasses legs 20 to the head of the user can be provided, the clamping force of the AR glasses is improved, and at the moment, the state of wearing the AR glasses is realized. When the hinge structure 10 extends inward from the natural state, the inclined ends 134 of the first engagement portion 11121 and the third engagement portion 1312 are in staggered contact (at this time, the inclined ends 134 of the second engagement portion 12121 and the fourth engagement portion 1313 are also in staggered contact), and the first direction of the first rotating member 111 and the second direction of the second rotating member 121 form an angle smaller than the obtuse angle in the natural state, and the included angle may be an obtuse angle, a right angle or an acute angle, which is suitable for the folding operation of the temple 20.

Specifically, in the present embodiment, the inward bending angle a is designed to provide a clamping force between the two temples 20 when the user wears the glasses normally in the natural state of the hinge structure 10, and the belleville spring may be designed to be in a pre-compressed state in the natural state to increase the compression amount of the compressed belleville spring and provide a larger repulsive force. The elastic force provided by the disc spring during pre-compression can synchronously provide damping force when the glasses legs 20 are bent inwards, and the damping force can be adjusted by adjusting the pre-compression amount of the disc spring, so that the hand feeling of a user is better when the user uses the glasses.
