[0001] The present invention relates to the technical field of intelligent head-mounted devices, and in particular to a pair of glasses. Background Art

[0002] Glasses are a kind of portable intelligent wearable display device. The glasses are equipped with waveguides and projection devices. The projection device projects the image onto the prism area on the free-form lens, so the user can see the projected virtual image superimposed on the picture in the physical environment. Existing glasses usually use dark or gradient shading protective lenses to shield the influence of external light on the imaging quality of the glasses. However, under different ambient light, a single, fixed color shading protective lens cannot meet the imaging effect requirements. Specific examples are as follows: when the external light is strong, the light-colored shading protective lens will make the user unable to see the image displayed on the glasses display; when the external light is weak, the dark shading protective lens will make the user unable to see the external scenery clearly.

[0003] In view of this, it is necessary to provide a new pair of glasses to solve or at least alleviate the above technical defects. Summary of the invention

[0004] The main purpose of the present invention is to provide a pair of glasses, aiming to solve the technical problem that the light transmittance of glasses cannot be adjusted in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides a frame, a dimming component and temples installed on the frame, the dimming component includes a driving member, a transmission member and two groups of lens parts, each group of the lens parts includes a correspondingly arranged polarizer and an analyzer, the polarizer is installed on the frame, the transmission member is respectively connected to the two analyzers, the driving member is connected to one of the analyzers to drive one of the analyzers to rotate, and then the other analyzer is driven to rotate synchronously through the transmission member to adjust the transmittance of the lens parts.

[0006] In some embodiments, the polarizer includes a first polarizer, the analyzer includes a second polarizer, and the driving member is transmission-connected to one of the second polarizers to drive one of the second polarizers to rotate, and then the other second polarizer is driven to rotate synchronously through the transmission member, so as to adjust the transmittance of the lens member by adjusting the angle between the polarization directions of the first polarizer and the corresponding second polarizer.

[0007] In some embodiments, the analyzer further includes a mounting frame, the second polarizer is mounted on the mounting frame, the driving member is transmission-connected to one of the mounting frames, and the transmission member is transmission-connected to two of the mounting frames respectively.

[0008] In some embodiments, the driving member includes a worm, wherein a first tooth is provided on one of the mounting frames, and the worm is drivingly connected to one of the mounting frames via the first tooth.

[0009] In some embodiments, the worm portion extends out of the frame.

[0010] In some embodiments, the transmission member includes a transmission gear, and second teeth are provided on the two mounting frames, and the transmission gear is respectively connected to the two mounting frames through the second teeth.

[0011] In some embodiments, the transmission gear includes a first gear and two second gears respectively meshing with the first gear, and the second gears are respectively transmission-connected to the corresponding mounting frame through the second teeth.

[0012] In some embodiments, the mounting frame is an annular frame with a mounting hole formed on the inner side of the annular frame, the second polarizer is arranged in the mounting hole, and the second tooth is arranged along a partial arc on the outer side of the mounting frame, and the central angle corresponding to the partial arc is not less than 90 degrees.

[0013] In some embodiments, the glasses further include a limiting bracket disposed in the frame, the limiting bracket being disposed on a side of the analyzer away from the polarizer, and the analyzer being rotatably mounted on the limiting bracket.

[0014] According to another aspect of the present invention, the present invention further provides a wearable smart device, wherein the wearable smart device comprises the glasses described above.

The polarizer is fixedly installed on the frame and is kept different. The two analyzers are connected by a transmission member, and one of the polarizers is connected to the driving member by transmission.

[0029] Reference Figure 1 and Figure 2The present invention provides a pair of glasses 100, comprising a frame 2, a dimming component and a temple 1 installed on the frame 2, the dimming component comprising a driving member 3, a transmission member 8 and two groups of lens components, each group of lens components comprising a correspondingly arranged polarizer 4 and an analyzer 5, the polarizer 4 is installed on the frame 2, the transmission member 8 is respectively connected to the two analyzers 5 in a transmission manner, the driving member 3 is connected to one of the analyzers 5 in a transmission manner to drive one analyzer 5 to rotate, and then the other analyzer 5 is driven to rotate synchronously through the transmission member 8 to adjust the light transmittance of the lens components.

[0030] It should be noted that the glasses 100 in the present invention refer to smart glasses, such as AR (Augmented Reality) glasses, VR (Virtual Reality) glasses or MR (Mixed Reality) glasses, and wearable smart devices can be used. There are two temples 1, and the two temples 1 are respectively arranged on the opposite sides of the frame 2. There are two groups of lens components, and each group of lens components includes a stacked polarizer 4 and an analyzer 5 respectively. The two lens components are arranged corresponding to the positions of two eyes of a person. The external light passes through the polarizer 4 and the analyzer 5 in turn and finally enters the human eye, and is received by the human eye, thereby obtaining an external image. An optical machine is also arranged in the frame 2. The light emitted by the optical machine is reflected by an optical machine lens 6 arranged separately in the frame 2 and then enters the human eye. Therefore, the human eye can receive the image information emitted by the optical machine, thereby realizing the combination of the real external image and the image emitted by the optical machine. Combined with reference Figure 3 , Figure 3 A represents external light, and B represents the two eyeballs of a person. Figure 3The schematic diagram of the lens component adjustment of the glasses 100 is shown. In the above embodiment of the present invention, the polarizer 4 is fixedly mounted on the frame 2, and is kept different. The two analyzers 5 are connected by the transmission member 8, and one of the polarizers 4 is connected to the driving member 3 by transmission. In this way, when the driving member 3 drives one of the analyzers 5 connected thereto to rotate, the transmission effect of the transmission member 8 can make the other analyzer 5 rotate synchronously, so as to achieve the synchronous adjustment of the two analyzers 5. The analyzer 5 rotates, while the corresponding polarizer 4 does not move, thereby achieving the adjustment of the polarization angle of the polarizer 4 and the analyzer 5 in each group of lens components, thereby playing the role of adjusting the transmittance of the lens components, and also adjusting the transmittance of the glasses 100. In a specific application, when the external light intensity is large, the driving member 3 can be driven to rotate in one direction to reduce the transmittance of the lens component and reduce the entry of external light; when the external light intensity is small, the driving member 3 can be driven to rotate in the opposite direction to increase the transmittance of the lens component and increase the entry of external light. It should be added that, assuming that the angle formed by the polarizer 4 and the analyzer 5 is θ, the relationship between the lens transmittance and the angle is (cos2θ) / 2 according to the well-known Malus law. Since θ can be continuously changed, the visible transmittance can also be continuously changed. This embodiment has a simple and reliable structure and is easy to adjust. It does not require the user to carry additional lenses to achieve stepless adjustment of the transmittance, and can achieve synchronous dimming of the two lens components.

[0031] Reference Figure 2 and Figure 4 In some embodiments, the polarizer 4 includes a first polarizer 41, the analyzer 5 includes a second polarizer 51, and the driving member 3 is connected to one of the second polarizers 51 to drive the second polarizer 51 to rotate, and then the other second polarizer 51 is driven to rotate synchronously through the transmission member 8, so as to adjust the light transmittance of the lens member by adjusting the angle between the polarization directions of the first polarizer 41 and the corresponding second polarizer 51. The first polarizer 41 and the second polarizer 51 are arranged in parallel and at a certain distance, and both the first polarizer 41 and the second polarizer 51 are circular. During the adjustment process, the first polarizer 41 remains stationary, and the second polarizer 51 rotates around its own center of circle. At this time, the angle θ between the polarizer 4 and the analyzer 5 refers to the angle θ of the polarization direction of the first polarizer 41 and the corresponding second polarizer 51. The second polarizer 51 is rotated by the driving member 3 to adjust the angle of the polarization direction of the first polarizer 41 and the corresponding second polarizer 51, so as to adjust the transmittance of the lens component. In addition, since the two second polarizers 51 rotate synchronously, the synchronous adjustment can also be achieved to adapt to different intensities of light from the outside.

[0032] Reference Figure 4 and Figure 5In some embodiments, the analyzer 5 further includes a mounting frame 52, a second polarizer 51 is mounted on the mounting frame 52, the driving member 3 is in transmission connection with one of the mounting frames 52, and the transmission member 8 is in transmission connection with the two mounting frames 52 respectively. In theory, the second polarizer 51 can be directly connected to the driving member 3 and the transmission member 8, but since the second polarizer 51 is generally brittle, it is easy to break. Therefore, a mounting frame 52 can be added to the frame 2, and the second polarizer 51 is set on the mounting frame 52. The driving member 3 and the transmission member 8 both drive the mounting frame 52 to rotate, so that the second polarizer 51 mounted on the mounting frame 52 rotates with the mounting frame 52, so as to adjust the angle between the polarization directions of the first polarizer 41 and the second polarizer 51, and finally adjust the light transmittance of the lens member.

[0033] Reference Figure 4 and Figure 5 In some embodiments, the driving member 3 includes a worm 31, wherein a first tooth 521 is provided on one of the mounting frames 52, and the worm 31 is connected to a mounting frame 52 through the first tooth 521. The worm 31 is provided with meshing teeth for meshing with the first tooth 521 on the mounting frame 52, so that when the worm 31 rotates, it can drive the mounting frame 52 to rotate. The mounting frame 52 is equivalent to a turbine, and forms a turbine-worm 31 transmission with the worm 31. Due to the self-locking characteristics of the turbine-worm 31 transmission, the rotation angle of the mounting frame 52 can only be driven by the worm 31, and the mounting frame 52 cannot drive the worm 31 to rotate. Therefore, the structure of the worm 31 adopted in this embodiment can effectively prevent the angle of the second polarizer 51 from being offset due to external interference such as vibration. In addition, since the worm gear 31 has a large transmission reduction ratio and a large adjustment stroke, the intensity adjustment of the incident light within a large range can be achieved. Refer to Figure 1 and Figure 2 At the same time, in order to make it unnecessary to remove the lens frame 2 during adjustment, the worm 31 can be partially extended out of the lens frame 2. In this way, the light transmittance can be adjusted by rotating the extended end of the worm 31 from outside the lens frame 2, which greatly improves the convenience of adjustment.

[0034] Reference Figure 4 and Figure 5 In some embodiments, the transmission member 8 includes a transmission gear 81, and the two mounting frames 52 are both provided with second teeth 522, and the transmission gear 81 is respectively connected to the two mounting frames 52 through the second teeth 522. The transmission gear 81 is meshed with two sets of second teeth 522 on the two mounting frames 52 at the same time, which can ensure the transmission accuracy and realize synchronous transmission, so as to ensure that the two analyzers 5 (or the two second polarizers 51) can be adjusted synchronously. When assembling the glasses 100, the polarization directions of the two polarizers 4 and the two analyzers 5 can be set to be consistent, so as to facilitate the subsequent synchronous adjustment.

[0035] Reference Figure 4and Figure 5 In some embodiments, the transmission gear 81 includes a first gear 811 and two second gears 812 respectively meshing with the first gear 811, and the second gears 812 are respectively connected to the corresponding mounting frame 52 through the second gears 522. The transmission gear 81 is composed of a gear set, specifically including a first gear 811 with a relatively large diameter and two second gears 812 with relatively small diameters. The first gear 811 is located between the two second gears 812 and meshes with the two second gears 812 respectively. Each second gear 812 meshes with the first gear 811 and also meshes with a mounting frame 52. The transmission connection between the two polarizers 5 is realized in the form of a gear set, and specifically the synchronous transmission connection between the two mounting frames 52 is realized. The connection mode of the transmission gear 81 can leave a larger space between the two polarizers 5, which is convenient for placing components such as cameras or sensors of the glasses 100.

[0036] Reference Figure 4 and Figure 5 In some embodiments, the mounting frame 52 is an annular frame, a mounting hole is formed on the inner side of the annular frame, the second polarizer 51 is arranged in the mounting hole, and the second gear 522 is arranged along a partial arc on the outer side of the mounting frame 52, and the central angle of the partial arc is not less than 90 degrees. The mounting frame 52 is an annular frame, and a mounting hole is formed on the inner side of the annular frame for mounting the second polarizer 51. The outer side of the annular frame may not be completely provided with the second gear 522, and the second gear 522 may only be provided at a part of the position. In order to ensure that the angle of the polarization direction of the polarizer 4 and the analyzer 5 of the same lens component can complete the angle change from 0° to 90°, the central angle corresponding to the arc of the mounting frame 52 provided with the second gear 522 cannot be less than 90 degrees, or it can be said that the length of the arc provided with the second gear 522 cannot be less than one quarter of the circumference of the mounting frame 52. Only in this way can it be ensured that the transmission member 8 can drive the analyzer 5 to rotate through the second engagement in an angle range of not less than 90 degrees. Similarly, on the mounting frame 52 connected to the worm 31 , the central angle of the arc provided with the first tooth 521 cannot be less than 90 degrees. In other words, the length of the arc provided with the first tooth 521 cannot be less than one quarter of the circumference of the mounting frame 52 .

[0037] Reference Figure 4 and Figure 5 In some embodiments, the glasses 100 further include a limiting bracket 7 disposed in the frame 2, the limiting bracket 7 being disposed on the side of the analyzer 5 away from the polarizer 4, and the analyzer 5 being rotatably mounted on the limiting bracket 7. The limiting bracket 7 is fixedly mounted on the frame 2, and a small gap is left between the limiting bracket 7 and the analyzer 5, and the limiting bracket 7 will not affect the rotation of the analyzer 5. The limiting bracket 7 can limit the analyzer 5 and the polarizer 4 in a direction perpendicular to the analyzer 5 and the polarizer 4 to reduce the shaking of the analyzer 5.
