Technical Field

The utility model belongs to the technical field of augmented reality and mixed reality, and particularly relates to a front frame of glasses and intelligent glasses.

Background

With the development of augmented Reality (Augmented Reality, abbreviated as AR) technology and Mixed Reality (MR) technology, the design requirements for glasses are higher and higher due to the fact that glasses are required for the application of the technologies.

The size of the front frame of the AR/MR glasses product is gradually reduced at present due to the size and strength of the AR/MR glasses product in the industry, and meanwhile, the prior art commonly uses metals such as aluminum alloy, magnesium-lithium alloy and the like and hard materials to manufacture the front frame of the glasses in consideration of meeting the binocular imaging requirement of human eyes. The front frame of the glasses is made of the materials, so that the size of the front frame of the glasses can be reduced on the premise of ensuring the strength of the front frame of the glasses. However, when the materials are stressed excessively, deformation which cannot be recovered is easily generated, for example, when the AR/MR glasses are worn on different using objects, an excessively large outward expansion angle is easily caused, so that the front frame of the glasses is bent, and after the glasses are taken down, the front frame of the glasses cannot rebound to an initial state.

In order to solve the above problems, the prior art proposes to manufacture a front frame of glasses by using plastic materials, although the deformation capability of the front frame of glasses can be improved, the front frame of glasses is adapted to the wearing requirements of different users, after the front frame of glasses is used, the front frame of glasses is easy to restore to the original state, but the overall strength of the plastic materials is smaller, especially the middle nose bridge is usually designed to be thinned for reducing the volume and adapting to the nose of a user, so that the middle nose bridge is bent too much, for example, the expansion angle is too large, the angle variation of lenses is large, thereby affecting the binocular image combining distance and finally affecting the use experience.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Before describing in detail the various embodiments of the present application, the technical concepts of the present application are first briefly described: in the prior art, a metal material or a hard material is adopted to manufacture the front frame of the glasses, when the front frame of the glasses is bent too much, irreversible deformation can be caused, if the front frame of the glasses is manufactured by adopting a plastic material, the front frame of the glasses has better restorability, but the strength is smaller, and the angle of the lenses can be greatly adjusted due to excessive deformation, so that the binocular imaging effect is influenced. For this reason, the glasses front frame that this application provided includes first lens frame, second lens frame and the intermediate junction spare of plastic material, sets up the reinforcement structure on the intermediate junction spare, can avoid intermediate junction spare excessively buckling to avoid the rotation angle of first lens frame and second lens frame great, can also guarantee simultaneously that the glasses front frame has good elasticity and resumes the performance.

Specifically, as shown in fig. 1, 2 and 3, the front frame 100 of the glasses of the first embodiment includes a first lens frame 10, a second lens frame 20 and a middle connecting member 30, two ends of the middle connecting member 30 are respectively fixedly connected with the first lens frame 10 and the second lens frame 20, the middle connecting member 30 is provided with a reinforcing structure 40, and the first lens frame 10, the second lens frame 20 and the middle connecting member 30 are all made of plastic materials. Wherein the intermediate connection 30 is a component that mates with the bridge of the nose of the user.

In one embodiment, the intermediate connection member 30 is a flat plate structure, and the reinforcing structure 40 is disposed on the inner side of the intermediate connection member 30, which is the side of the intermediate connection member 30 facing the user when the user wears the smart glasses.

Illustratively, in another embodiment, the intermediate connector 30 includes a first horizontal portion 31, a second horizontal portion 32, and a vertical portion 33, the first horizontal portion 31 and the second horizontal portion 32 being disposed opposite, the vertical portion 33 being disposed between the first horizontal portion 31 and the second horizontal portion 32 to collectively form a semi-enclosed structure, the reinforcing structure 40 being disposed within the semi-enclosed structure. Wherein, the two ends of the first horizontal portion 31, the two ends of the second horizontal portion 32 and the two ends of the vertical portion 33 are respectively connected with the first lens frame 10 and the second lens frame 20. The intermediate connector 30 can be regarded as a "hollow" structure, which reduces the weight of the central connector 30 itself and ensures a high supporting strength. Meanwhile, the reinforcing structure 40 is arranged in the middle connecting piece 30, so that the size of the front frame 100 of the glasses can be further reduced, the degree of combination of the reinforcing structure 40 and the middle connecting piece 30 can be improved, and the supporting strength of the middle connecting piece 30 can be improved.

Illustratively, the thickness of the first horizontal portion 31, the thickness of the second horizontal portion 32 and the thickness of the vertical portion 33 may be thickened such that the thicknesses of the three exceed the thicknesses of the first lens frame 10 and the second lens frame 20, which may enhance the overall strength of the front frame 100 without significantly increasing the overall weight of the front frame 100. For example, the thickness of the first horizontal portion 31, the thickness of the second horizontal portion 32, and the thickness of the vertical portion 33 are set to be greater than or equal to 0.8mm. In practical cases, of course, the thickness value may be set as desired.

Further, the second horizontal portion 32 is located below the first horizontal portion 31, and the second horizontal portion 32 is an arc plate recessed toward the first horizontal portion 31, so that the second horizontal portion 32 is adapted to the nose bridge profile of the user. The first horizontal portion 31 and the vertical portion 33 may be provided as flat plates, for example.

Further, the two ends of the reinforcing structure 40 are respectively connected with the first lens frame 10 and the second lens frame 20, so that the connection stability of the reinforcing structure 40, the intermediate connecting piece 30 and the first lens frame 10 and the second lens frame 20 can be further improved, and the overall strength of the front frame of the glasses can be further improved.

Specifically, the reinforcing structure 40 includes at least two reinforcing bars. Illustratively, a portion of the reinforcing ribs are disposed horizontally (as indicated by reference numeral 41 in fig. 2) and another portion of the reinforcing ribs are disposed vertically (as indicated by reference numeral 42 in fig. 2), so that the supporting strength of the reinforcing structure 40 can be improved. In another embodiment, the reinforcing ribs are connected to each other to form a cross structure, so that the supporting strength of the reinforcing structure 40 can be improved. Wherein, the shape of each strengthening rib can be strip shape, cylindric, and the size of strengthening rib can be set for according to actual demand. In another embodiment, the partial ribs located in the middle region of the reinforcing structure 40 are cross-linked and the partial ribs located on both sides of the middle region are horizontally disposed.

Illustratively, the reinforcing structure 40 is preferably made of plastic, so that the weight of the reinforcing structure 40 can be reduced, and the reinforcing structure 40 is in the form of a reinforcing rib, so that a large supporting strength can be ensured even if the reinforcing structure is made of plastic. In the process of manufacturing the reinforcing structure 40, the reinforcing structure 40 may be integrally formed with the intermediate connecting member 30, the first lens frame 10, and the second lens frame 20.

Further, the plastic material of the first embodiment is preferably capable of ensuring that the front frame of the glasses does not generate plastic deformation within 20 degrees of bending, that is, the front frame of the glasses is still capable of being restored to its original shape after being released within 20 degrees of bending. For example, the plastic material may be selected from a PC material, a composite material of PC and carbon fiber, a composite material of PC and glass fiber, a composite material of TR90 and carbon fiber, a composite material of TR90 and glass fiber, and a composite material of carbon fiber and PMMA.

As shown in fig. 4 and 5, the smart glasses of the second embodiment include a first glasses leg 50, a second glasses leg 60, and a front glasses frame of the first embodiment, the first glasses leg 50 is rotatably connected to a side of the first glasses frame 10 far away from the intermediate connecting member 30, and the second glasses leg 60 is rotatably connected to a side of the second glasses frame 20 far away from the intermediate connecting member 30.

Illustratively, the first temple 50 has a rotational angle in the range of 0 degrees to 100 degrees relative to the first lens frame 10 and the second temple 60 has a rotational angle in the range of 0 degrees to 100 degrees relative to the second lens frame 20. Wherein, when the rotation angle of the first temple 50 relative to the first lens frame 10 is 0 degrees, the first temple 50 is in a fully retracted state, and when the rotation angle of the first temple 50 relative to the first lens frame 10 is 100 degrees, the first temple 50 is in a fully extended state. Illustratively, the first temple 50 is in a fully retracted state, the first temple 50 being parallel to the first lens frame 10; when the first temple 50 is in the fully unfolded state, the first temple 50 and the first lens frame 10 form an obtuse angle with each other. Similarly, the relative relationship of the second temple 60 to the second lens frame 20 may be analyzed similarly as described above, and is omitted herein.

Generally speaking, the range of the relative rotation angle of the temple with respect to the lens frame is 0 to 90 degrees, that is, when the temple is fully unfolded, the temple is perpendicular to the lens frame, but if different users wear the glasses, when the temple is fully unfolded, the temple is pressed when the head or face of a user is larger, that is, the temple is pushed to expand, at this time, the nose bridge between the two lens frames is expanded outwards due to the fact that the temple cannot rotate relative to the lens frames, so that the angles of the lenses on the two lens frames are changed, and if the angles of the lenses are changed greatly, the binocular imaging distance of the two lenses exceeds the predetermined range, and the imaging effect is affected. The determining factors of the binocular image combining distance include a lens angle and a relative angle between the optical machine and the lens, wherein the optical machine is fixed on the lens by dispensing, and the relative angle between the optical machine and the lens is fixed; the lens frame is kept away from the optical machine and the lens frame, so that the deformation of the lens frame does not affect the angle of the optical machine, but the deformation of the lens frame affects the angle of the lens. Therefore, the angle of the lens frame is controlled, namely the angle of the lens is controlled, so that the image combining distance can be kept in an ideal range.

In the second embodiment, the rotation angle of the first temple 50 relative to the first lens frame 10 ranges from 0 degrees to 100 degrees, and the rotation angle of the second temple 60 relative to the second lens frame 20 ranges from 0 degrees to 100 degrees, and compared with the conventional scheme, the rotation angles of the first temple 50 and the second temple 60 are expanded by 10 degrees, so that the two-dimensional glasses can be suitable for more diverse wearing groups. For example, when a user encounters a large head or face, the first and second temples 50 and 60 can be further expanded, so as to avoid greatly expanding the angle of the intermediate connecting member 30, and avoid excessively deforming the first and second lens frames 10 and 20, so that the expansion angles of the two lenses are controlled within a reasonable range.

Further, the first temple 50 and the first lens frame 10 are hinged to each other, and the second temple 60 and the second lens frame 20 are hinged to each other. Illustratively, the smart glasses further include a first hinge mechanism 70 and a second hinge mechanism 80, the first hinge mechanism 70 is disposed between the first temple 50 and the first lens frame 10, and the second hinge mechanism 80 is disposed between the second temple 50 and the second lens frame 20.

Illustratively, the first hinge mechanism 70 and the second hinge mechanism 80 may employ elastic hinges so as to have a certain resilience force when the first and second temples 50 and 60 are rotated to different angles, so as to be more stably worn on the user's head. Alternatively, the first hinge mechanism 70 and the second hinge mechanism 80 may have different rotational gears, and when the first and second temples 50 and 60 are rotated to a certain angle, the first and second hinge mechanisms 70 and 80 have a large damping, and do not easily continue to rotate, so that the stability of the first and second temples 50 and 60 at the current angle can be maintained. It should be noted that, the first hinge mechanism 70 and the second hinge mechanism 80 may also be similar to those described above, and the second embodiment is not limited thereto.

As one embodiment, when the first and second lens legs 50 and 60 are rotated to the maximum expansion angle, that is, when both the first and second lens legs 50 and 60 are rotated to 100 degrees, the maximum expansion force bearable by the first and second lens legs 50 and 60 is 200g, and under the action of the intermediate connecting piece 30 and the reinforcing structure 40, the relative angle between the first and second lens frames 10 and 20 can be expanded by 5 degrees at the maximum expansion force, so that the relative expansion angles of the two lenses on the first and second lens frames 10 and 20 can be controlled to be in the range of 0 to 5 degrees, and the image combining distance of the smart glasses can be in the range of 0.5m-5m, so that the smart glasses can be normally used.

For example, the smart glasses of the first embodiment may be AR glasses, VR glasses, and MR glasses. The smart glasses further include a first lens 11 mounted on the first lens frame 10, and a second lens 21 mounted on the second lens frame 20.

Further, as shown in fig. 6, the smart glasses further include a rear glasses frame 200, and the rear glasses frame 200 and the front glasses frame 100 are connected in a matching manner to form a complete glasses frame body. A bridge support 90 is provided at a middle position of the rear frame 200 of the glasses, i.e., a position corresponding to the middle connection member 30. It should be noted that, it should be understood that the complete smart glasses should also have other necessary basic components, but other components are not important to the present embodiment, and thus are not shown in the drawings and not described in detail in the specification, and are well known to those skilled in the art.

While certain embodiments have been shown and described, it would be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles and spirit of the utility model, the scope of which is defined in the claims and their equivalents.
