[0029] Reference Figure 1 and Figure 2The present invention provides a pair of glasses 100, comprising a frame 2, a dimming assembly and a temple 1 mounted on the frame 2, the dimming assembly comprising a driving member 3, a transmission member 8 and two groups of lens components, each group of lens components comprising a corresponding polarizer 4 and an analyzer 5, the polarizer 4 being mounted on the frame 2, the transmission member 8 being respectively connected to the two analyzers 5 in a transmission manner, the driving member 3 being connected to one of the analyzers 5 in a transmission manner to drive one analyzer 5 to rotate, and then driving the other analyzer 5 to rotate synchronously through the transmission member 8 to adjust the 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 can be used with wearable smart devices. 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 parts, and each group of lens parts includes a stacked polarizer 4 and an analyzer 5 respectively. The two lens parts 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 provided in the frame 2. The light emitted by the optical machine is reflected by an optical machine lens 6 provided 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 3A schematic diagram illustrating the principle of adjusting the lens components 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 remains separate. Two analyzers 5 are connected via a transmission member 8, one of which is in transmission connection with the driver 3. Thus, when the driver 3 drives one of the analyzers 5 connected thereto to rotate, the transmission member 8 causes the other analyzer 5 to rotate synchronously, achieving synchronous adjustment of the two analyzers 5. The analyzer 5 rotates while the corresponding polarizer 4 remains stationary. This allows adjustment of the polarization angle between the polarizer 4 and analyzer 5 in each lens group, thereby adjusting the transmittance of the lens components and, consequently, the transmittance of the glasses 100. In a specific application, when the intensity of external light is high, the driver 3 can be driven to rotate in one direction to reduce the transmittance of the lens components, thereby reducing the entry of external light. When the intensity of external light is low, the driver 3 can be driven to rotate in the opposite direction to increase the transmittance of the lens components, thereby increasing the entry of external light. It should be noted that, assuming the angle θ formed by polarizer 4 and analyzer 5 is θ, the relationship between lens transmittance and this angle is (cos2θ) / 2, according to the well-known Malus law. Since θ can be continuously varied, the transmittance can also be continuously varied. This embodiment has a simple and reliable structure and is easy to adjust. It allows for stepless adjustment of transmittance without the user having to carry additional lenses, and can also achieve synchronized dimming of both lens elements.
[0031] Reference Figure 2 and Figure 4 In some embodiments, the polarizer 4 includes a first polarizer 41, and the analyzer 5 includes a second polarizer 51. The driver 3 is in transmission connection with one of the second polarizers 51 to drive the rotation of the second polarizer 51, which in turn drives the other second polarizer 51 to rotate synchronously via the transmission member 8. The transmittance of the lens component is adjusted 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 parallel to each other and spaced a certain distance apart. 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 between the polarization directions of the first polarizer 41 and the corresponding second polarizer 51. The driving member 3 is used to rotate the second polarizer 51 to adjust the angle between the polarization directions 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, on which the second polarizer 51 is mounted. The driver 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. Theoretically, the second polarizer 51 can be directly connected to the driver 3 and the transmission member 8. However, since the second polarizer 51 is generally brittle and easily broken, a mounting frame 52 can be added to the frame 2. The second polarizer 51 is set on the mounting frame 52. The driver 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 along with the mounting frame 52, thereby adjusting the angle between the polarization directions of the first polarizer 41 and the second polarizer 51, and ultimately adjusting the transmittance of the lens component.
[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 engaging 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 can be achieved within a large range. Refer to Figure 1 and Figure 2 At the same time, in order to make it unnecessary to remove the frame 2 during adjustment, the worm 31 can be partially extended from the frame 2. In this way, the transmittance can be adjusted by rotating the extended end of the worm 31 from outside the 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. Second teeth 522 are provided on both mounting frames 52. The transmission gear 81 is connected to the two mounting frames 52 via the second teeth 522. The transmission gear 81 simultaneously engages with two sets of second teeth 522 on the two mounting frames 52, ensuring both transmission accuracy and synchronous transmission, ensuring synchronized adjustment of the two analyzers 5 (or, more accurately, the two second polarizers 51). When assembling the glasses 100, the polarization directions of the two polarizers 4 and the two analyzers 5 can be aligned to facilitate subsequent synchronized 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. The second gears 812 are respectively connected to the corresponding mounting brackets 52 via second teeth 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 bracket 52. The gear set realizes a transmission connection between the two polarizers 5, specifically realizing a synchronous transmission connection between the two mounting brackets 52. The connection method using 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 having a mounting hole formed on its inner side, the second polarizer 51 being mounted in the mounting hole, and the second teeth 522 being arranged along a portion of the arc on the outer side of the mounting frame 52, with the central angle corresponding to the portion of the arc being no less than 90 degrees. The mounting frame 52 is an annular frame having a mounting hole formed on its inner side for mounting the second polarizer 51. The outer side of the annular frame may not be entirely provided with the second teeth 522, but may be provided with the second teeth 522 in only a portion of the outer side. To ensure that the angle between the polarization directions of the polarizer 4 and the analyzer 5 of the same lens component can be varied from 0° to 90°, the central angle corresponding to the arc on the mounting frame 52 having the second teeth 522 cannot be less than 90 degrees. In other words, the length of the arc having the second teeth 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 to an angle range of no less than 90 degrees. Similarly, on the mounting frame 52 connected to the worm 31 , the central angle of the arc on which the first tooth 521 is provided cannot be less than 90 degrees. In other words, the length of the arc on which the first tooth 521 is provided 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 within the frame 2. The limiting bracket 7 is disposed on a side of the analyzer 5 facing away from the polarizer 4, and the analyzer 5 is rotatably mounted on the limiting bracket 7. The limiting bracket 7 is fixedly mounted to the frame 2 with a small gap between it and the analyzer 5. The limiting bracket 7 does 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 shaking of the analyzer 5.

Since the wearable smart device incorporates all technical solutions of all embodiments of the aforementioned glasses 100, it possesses at least all the beneficial effects of all the aforementioned technical solutions, which will not be detailed here.
