[0037] Optical elements refer to devices or components used to control and manipulate the propagation of light and modulate the properties of light (such as intensity, phase, polarization, etc.) to achieve optical functions.

[0038] In the field of optics, optical frames are important parts used to fix and adjust the angle and distance of optical components. During laser transmission, optical components are irradiated by high-temperature and high-frequency beams, which causes thermal deformation of the optical components, thus affecting the performance of the optical components.

[0039] However, the optical frame in the related art lacks a heat dissipation method for the optical elements.

[0040] In order to at least solve the problem that the optical frame in the related art lacks a heat dissipation method for the optical element, the embodiment of the present application proposes an optical frame 110 that can dissipate heat for the optical element 120.

[0041] The embodiment of the present application further provides an optical device 100 including the optical frame 110 of the above embodiment.

[0042] The optical frame 110 and the optical device 100 according to the embodiment of the present application are described below with reference to the accompanying drawings.

[0043] Combination Figure 1 , Figure 2 and Figure 3 As shown, the optical frame 110 of the embodiment of the present application includes: a support assembly 1, an air supply assembly 2 and a fixing frame 3. The support assembly 1 defines an air supply channel 111; the air supply assembly 2 is arranged on the support assembly 1, and the air supply assembly 2 is configured to be able to supply air into the air supply channel 111; the fixing frame 3 is connected to the support assembly 1, and the fixing frame 3 defines a guide cavity 311 and a mounting cavity 321, the guide cavity 311 is formed with an air inlet 312 communicating with the air supply channel 111, and the guide cavity 311 is also formed with an air outlet 322 communicating with the mounting cavity 321, and the mounting cavity 321 is used to mount the optical element 120.

[0044] As some examples, the optical element 120 may be a reflective element, such as a plane lens or a reflective lens. The optical element 120 may also be a refractive element, such as a convex lens, a concave lens or a prism. The optical element 120 may also be a diffraction element, such as a grating or a Fresnel lens. The optical element 120 may also be a polarizing element, such as a polarizing plate or a wave plate. The optical element 120 may also be a filter element, such as a filter lens.

[0045] It should be noted that the above examples only exemplarily list some types of optical elements 120 , and the optical element 120 may also be other types of elements.

[0046] The support assembly 1 defines an air supply channel 111, so that the wind delivered by the air supply assembly 2 flows stably in the air supply channel 111, reducing air flow turbulence and energy loss. The guide cavity 311 of the fixing frame 3 is connected to the air supply channel 111, and the wind from the air supply channel 111 can enter the guide cavity 311 smoothly through the air inlet 312. The airflow can be rectified through the guide cavity 311, so that the wind blown out from the air outlet 322 is more uniform, reducing the probability of excessive or insufficient local wind speed, which is conducive to uniform air cooling and heat dissipation of the optical element 120 in the installation cavity 321. After being guided and constrained by the guide cavity 311, the airflow flows to the air outlet 322 in a more orderly manner, and the airflow enters the installation cavity 321 through the air outlet 322, so as to be able to dissipate heat for the optical element 120 in the installation cavity 321.

[0047] The air flow velocity in the installation cavity 321 is relatively high, and the pressure in the installation cavity 321 is relatively low. There is a pressure difference between the inside and outside of the installation cavity 321, so that the air outside the installation cavity 321 is pressed into the installation cavity 321, thereby increasing the air flow intensity in the installation cavity 321, thereby increasing the heat dissipation effect of the optical element 120 in the installation cavity 321.

[0048] In addition, the support assembly 1, the air supply assembly 2 and the fixing frame 3 are connected to each other to form a relatively compact overall structure. Through the positional relationship between the support assembly 1, the air supply assembly 2 and the fixing frame 3, the air supply channel 111, the guide cavity 311 and the installation cavity 321 are integrated, so that the space can be efficiently utilized, and the volume of the optical frame 110 can be reduced, which is conducive to the miniaturization of the optical frame 110.

[0049] Combination Figure 1 and Figure 2 As shown, in some embodiments, the installation cavity 321 forms openings at both ends of the first direction a, the installation cavity 321 has an installation position 3211 for installing the optical element 120 , and the air outlet 322 faces the installation position 3211 .

[0050] As an example, the first direction a is the axial direction of the fixing frame 3 .

[0051] The air outlet 322 faces the installation position 3211 , so that the airflow flowing out of the guide cavity 311 can directly act on the optical element 120 at the installation position 3211 , thereby taking away the heat of the optical element 120 in time, thereby improving the heat dissipation effect on the optical element 120 .

[0052] The air enters the installation cavity 321 from the air supply channel 111 through the guide cavity 311 and flows out from the opening at one end of the installation cavity 321 away from the air outlet 322, forming a complete air flow cycle and enhancing the heat dissipation effect.

[0053] The air flow out of the air outlet 322 has a fast flow rate, resulting in the pressure inside the installation cavity 321 being lower than the pressure outside the installation cavity 321. Under the action of the pressure difference between the inside and outside of the installation cavity 321, the outside air enters the installation cavity 321 through the opening at one end of the installation cavity 321 close to the air outlet 322, so as to act on the optical element 120 at the installation position 3211, and flows out from the opening at one end of the installation cavity 321 away from the air outlet 322, thereby forming a complete airflow cycle to further enhance the heat dissipation effect.

[0054] Thus, the installation cavity 321 forms openings at both ends of the first direction a, which is conducive to the formation of a smooth flow path for air in the installation cavity 321, thereby enhancing the heat dissipation effect and reducing the negative effects caused by air flow turbulence.

[0055] In addition, the installation cavity 321 is open at both ends, which provides a convenient operating space for the installation and removal of the optical element 120, thereby increasing the convenience of maintenance work.

[0056] Combination Figure 1 and Figure 2 As shown, in some embodiments, the fixing frame 3 includes a first frame 31, a second frame 32 and a guide portion 33, the first frame 31 is connected to the supporting assembly 1 and is formed with an air inlet 312, the first frame 31 is arranged outside the second frame 32, one end of the first frame 31 is connected to the second frame 32, the other end of the first frame 31 is connected to the guide portion 33, the second frame 32 cooperates with the guide portion 33 and defines an air outlet 322, a guide cavity 311 is defined between the first frame 31, the second frame 32 and the guide portion 33, and the second frame 32 defines an installation cavity 321.

[0057] By reasonably designing the shapes and connection methods of the first frame 31, the second frame 32 and the guide portion 33, a reasonable layout of the guide cavity 311 and the mounting cavity 321 is achieved within a limited space, thereby fully utilizing space resources and making the structure of the optical frame 110 of this embodiment more compact, thereby improving the integration and portability of the system, and further reducing the volume of the system, which is conducive to the miniaturization of the optical frame 110.

[0058] In addition, by connecting the first frame 31 to the support assembly 1, the first frame 31, the second frame 32 and the air guide 33 are supported, making the structure of the optical frame 110 of this embodiment more solid and reliable. The first frame 31 is arranged outside the second frame 32, and the two ends are respectively connected to the second frame 32 and the air guide 33, thereby enhancing the structural stability between the various parts of the fixing frame 3, being able to effectively resist external impact and vibration, and ensuring the stability of the system during operation.

[0059] It should be explained here that one end of the first frame 31 is connected to the second frame 32, which can be connected by integral molding or by separate molding, and no excessive restrictions are made here. The other end of the first frame 31 is connected to the guide portion 33, which can be connected by integral molding or by separate molding, and no excessive restrictions are made here.

[0060] like Figure 2 As shown, in some optional embodiments, the first frame 31 further includes a main body 313 and a flow guide 314 , the main body 313 is arranged opposite to the second frame 32 , and one end of the main body 313 is connected to the second frame 32 through the flow guide 314 .

[0061] The guide body 314 can guide the airflow. When the airflow enters the space between the main body 313 and the second frame 32, the guide body 314 can make the airflow flow in a specific direction, thereby guiding the airflow to turn, so that the airflow flows from the main body 313 to the second frame 32, or from the second frame 32 to the main body 313, so that the gas flows in the guide cavity 311 in an orderly manner.

[0062] It should be explained here that one end of the main body 313 is connected to one end of the second frame 32 through the guide body 314, and the main body 313 and the guide body 314 can be connected by integral molding or by being connected after being formed separately, and no excessive restrictions are made here. The guide body 314 and the second frame 32 can be connected by integral molding or by being connected after being formed separately, and no excessive restrictions are made here.

[0063] like Figure 2 As shown, further, one end of the second frame 32 away from the flow guiding portion 33 is connected to the flow guiding portion 314 .

[0064] One end of the second frame 32 away from the guide portion 33 is connected to the guide body 314, which increases the space utilization rate and is able to increase the volume of the guide cavity 311, so that the guide cavity 311 can accommodate more airflow, thereby providing more sufficient flow space for the airflow, thereby improving the carrying capacity and transmission efficiency of the guide cavity 311 for the airflow.

[0065] In some optional embodiments, the flow guide 314 and the main body 313 are connected with each other by a smooth transition so as to reduce energy loss of the airflow between the flow guide 314 and the main body 313 .

[0066] Smooth transition connection means that there are no obvious protrusions, depressions or gaps at the connection, so that the airflow can smoothly pass through the connection part when flowing, reduce the resistance and energy loss, and improve the efficiency and stability of the airflow in the guide cavity 311.

[0067] In some optional embodiments, the flow guide 314 and the second frame 32 are connected with each other through a smooth transition to reduce energy loss of the airflow between the flow guide 314 and the second frame 32 .

[0068] Combination Figure 1 and Figure 2 As shown, in some embodiments, in the first direction a, the first frame 31 and the second frame 32 are both located on the same side of the air guide 33. In the second direction b, one end of the second frame 32 is located between the two ends of the air guide 33, one end of the air guide 33 cooperates with one end of the second frame 32 to form a gap, and the gap is configured as an air outlet 322, and the first direction a is perpendicular to the second direction b.

[0069] As an example, the second direction b is the inward and outward direction of the fixing frame 3 .

[0070] In the first direction a, the first frame 31 and the second frame 32 are both located on the same side of the guide portion 33, which can increase space utilization and increase the volume of the guide cavity 311, so that the guide cavity 311 can accommodate more airflow, thereby providing more sufficient flow space for the airflow, thereby improving the carrying capacity and transmission efficiency of the guide cavity 311 for the airflow.

[0071] The air outlet 322 is formed by the gap formed by one end of the guide portion 33 and one end of the second frame 32, so that the air outlet 322 has a smaller size. According to the Bernoulli principle, when the airflow passes through a narrow gap, the flow rate increases. Therefore, when the gas flows out of the air outlet 322, the flow rate increases, thereby increasing the heat dissipation effect on the optical element 120 in the installation cavity 321.

[0072] In addition, the gap formed by one end of the air guide 33 and one end of the second frame 32 can play a buffering role to a certain extent. When affected by factors such as thermal expansion and contraction, mechanical vibration, etc., the gap can provide space for slight deformation or displacement of the air guide 33 and the second frame 32, thereby protecting the integrity and stability of the structure.

[0073] like Figure 2As shown, in some optional embodiments, the guide portion 33 includes a first guide section 331 connected to the first frame 31 and a second guide section 332 that cooperates with the second frame 32 to form a gap, the first guide section 331 has a connection end connected to the first frame 31, and the second guide section 332 has a matching end that cooperates with the second frame 32. The first guide section 331 and the second guide section 332 are smoothly transitionally connected to each other, in the direction of the first guide section 331 away from the connection end, the first guide section 331 is away from the installation position 3211 in the first direction a, and in the direction of the second guide section 332 close to the matching end, the second guide section 332 is close to the installation position 3211 in the first direction a.

[0074] By setting the first guide section 331 and the second guide section 332, and making the first guide section 331 away from the connection end in the direction of the first guide section 331, and away from the installation position 3211 in the first direction a, and the second guide section 332 close to the mating end in the direction of the second guide section 332, the second guide section 332 is close to the installation position 3211 in the first direction a, so that the airflow can more smoothly attach to the first guide section 331 and the second guide section 332 when passing through the first guide section 331 and the second guide section 332, thereby reducing the probability of airflow turbulence, so as to reduce the energy loss of the airflow through the guide portion 33 and improve the efficiency of the airflow passing through.

[0075] It should be explained here that the first guide section 331 and the second guide section 332 are connected to each other in a smooth transition, and can be connected in one piece or connected after being formed separately, without making too many restrictions here. The first frame 31 is connected to the first guide section 331, or can be connected after being formed separately, without making too many restrictions here.

[0076] As an example, the air guide portion 33 is arc-shaped.

[0077] like Figure 2 As shown, in some optional embodiments, one end of the air guide portion 33 that cooperates with the second frame 32 faces the installation position 3211.

[0078] One end of the air guide portion 33 that cooperates with the second frame 32 faces the installation position 3211 , so as to guide the airflow flowing into the installation cavity 321 , so that the airflow can flow to the installation position 3211 more accurately.

[0079] like Figure 2 As shown, in some embodiments, the second frame 32 includes a protruding section 323 and a mounting section 324 that are connected to each other. The mounting section 324 is connected to the first frame 31 and defines a mounting position. The protruding section 323 cooperates with the guide portion 33 to form a gap. In the second direction b, the protruding section 323 protrudes inward relative to the mounting section 324.

[0080] The overall structure of the second frame 32 is streamlined to a certain extent by the protruding section 323 and the mounting section 324. When the airflow flows through the second frame 32, it can flow smoothly along the surface of the protruding section 323 to reduce the turbulence of the airflow and the generation of eddies, thereby reducing the airflow resistance, and further improving the heat dissipation effect of the airflow on the optical element 120.

[0081] In addition, the airflow can be guided by the protruding section 323 and the mounting section 324 so that the airflow discharged from the air outlet 322 moves along the surfaces of the protruding section 323 and the mounting section 324 to the mounting position 3211, thereby improving the efficiency of the airflow on the optical element 120 and further improving the heat dissipation effect of the airflow on the optical element 120.

[0082] It should be explained here that the protruding section 323 and the mounting section 324 are connected to each other, and may be connected by integral molding or by separate molding and then connected together, and no further restrictions are imposed here.

[0083] In some optional embodiments, the curvature of the part where the protruding section 323 and the guide portion 33 cooperate with each other is the same.

[0084] The curvature of the part where the protruding section 323 and the air guide portion 33 cooperate with each other is the same, and when the airflow flows toward the protruding section 323, the probability of airflow separation, turbulence, etc. caused by the sudden change of surface curvature can be reduced, thereby reducing the energy loss of the airflow, reducing the flow resistance of the airflow, and further improving the heat dissipation effect of the airflow on the optical element 120.

[0085] like Figure 2 As shown, in some optional embodiments, the protruding section 323 and the mounting section 324 are smoothly transitionally connected to reduce energy loss of the airflow between the protruding section 323 and the mounting section 324 .

[0086] In some optional embodiments, the second frame 32 is streamlined.

[0087] When the airflow passes through the second frame 32 , it can flow smoothly along the surface of the second frame 32 to reduce the turbulence of the airflow and the generation of eddies, thereby reducing the airflow resistance and further increasing the heat dissipation effect of the airflow on the optical element 120 .

[0088] Combination Figure 1 and Figure 3 As shown, in some embodiments, the support assembly 1 includes a support rod 11 and a base 12, one end of the support rod 11 is connected to the fixing frame 3, and the other end of the support rod 11 is connected to the base 12, the support rod 11 defines an air supply channel 111, and the base 12 defines an accommodating cavity 122 connected to the air supply channel 111, and the air supply assembly 2 is disposed in the accommodating cavity 122.

[0089] The support rod 11 connects the fixing frame 3 and the base 12 to form a stable supporting structure. The support rod 11 can effectively transfer the weight of the fixing frame 3 and the components connected to the fixing frame 3 to the base 12, and the base 12 distributes the weight to the supporting surface, thereby improving the stability of the optical frame 110 of this embodiment and reducing the probability of the optical frame 110 of this embodiment shaking or tipping over due to external force or its own weight.

[0090] The air supply channel 111 defined by the support rod 11 is in communication with the accommodating cavity 122 defined by the base 12 , so that the air flow delivered by the air supply assembly 2 has a clear flow path.

[0091] The airflow enters the air supply channel 111 from the accommodating cavity 122 where the air supply component 2 is located, and then flows along the air supply channel 111 to the fixing frame 3 and its related components, thereby achieving targeted airflow delivery, thereby improving the transmission efficiency of the airflow.

[0092] By respectively providing an air supply channel 111 and a receiving cavity 122 in the support rod 11 and the base 12, the space occupied by the support rod 11 is effectively utilized, the supporting function and the air supply function are combined with each other, and it is avoided to separately provide a complex pipeline or space for realizing the air supply function, so that the structure of the optical frame 110 of this embodiment is more compact, which is further conducive to the miniaturization of the optical frame 110 of this embodiment.

[0093] The accommodating cavity 122 of the base 12 accommodates the air supply component 2 to provide protection for the air supply component 2, prevent the air supply component 2 from being affected by external environmental factors, reduce the possibility of damage to the air supply component 2, thereby extending the service life of the air supply component 2 and ensuring the stability and reliability of the performance of the air supply component 2.

[0094] Placing the air supply assembly 2 in the accommodating cavity 122 and guiding the airflow through the air supply channel 111 of the support rod 11 can prevent the airflow from being exposed outside the optical frame 110, thereby reducing the probability of impurities being mixed into the airflow and further improving the cleanliness of the airflow.

[0095] Combination Figure 1 and Figure 3 As shown, in some embodiments, the air supply assembly 2 includes a fan 21 and an impeller 22, the fan 21 and the impeller 22 are transmission-connected, the fan 21 and the impeller 22 are both disposed in an accommodating cavity 122, and the base 12 is provided with a plurality of through holes 121 connecting the inside and outside of the accommodating cavity 122, and at least some of the through holes 121 are disposed corresponding to the impeller 22.

[0096] The through hole 121 on the base 12 corresponding to the impeller 22 can allow the outside air to smoothly enter the accommodating chamber 122. The impeller 22 rotates under the drive of the fan 21, generating negative pressure, so that the surrounding air is sucked into the accommodating chamber 122 through the through hole 121, and the through hole 121 can provide an air source for the air supply component 2, thereby ensuring that the air supply component 2 can supply air normally.

[0097] The through hole 121 corresponding to the impeller 22 can make the air flow to the impeller 22 more directly, reducing the resistance of the airflow entering the accommodating chamber 122. The impeller 22 can more efficiently capture and push the air entering the accommodating chamber 122 and convert it into a supply airflow. As a result, the utilization rate of the air by the fan 21 and the impeller 22 can be improved, thereby improving the air supply efficiency of the air supply assembly 2.

[0098] The plurality of through holes 121 provide a larger air intake area, so that more air can enter the accommodating chamber 122 per unit time. Thus, the impeller 22 can process more air when rotating, thereby increasing the flow rate and pressure of the air supply.

[0099] Even if some of the through holes 121 are blocked, the other through holes 121 can still ensure a certain degree of air circulation and maintain the basic function of the air supply assembly 2, thereby improving the stability and reliability of the optical frame 110 of this embodiment.

[0100] Combination Figure 1 and Figure 3 As shown, in some embodiments, the air supply assembly 2 also includes a guide vane 23 disposed in the accommodating cavity 122, one end of the guide vane 23 is disposed opposite to the air supply channel 111, and the other end of the guide vane 23 is disposed opposite to the impeller 22, and the guide vane 23 is configured to guide the airflow generated by the impeller 22 into the air supply channel 111.

[0101] The guide vanes 23 can accurately guide the airflow generated by the impeller 22 into the air supply channel 111, thereby improving the efficiency of the airflow entering the air supply channel 111 and improving the controllability and accuracy of the airflow delivery.

[0102] In some optional embodiments, the guide vanes 23 are fixed radial guide vanes.

[0103] The fixed radial guide vanes can stably guide the airflow generated by the impeller 22 to the air supply channel 111, so that the airflow direction is changed from the direction generated by the rotation of the impeller 22 to a direction more suitable for entering the air supply channel 111. The fixed radial guide vanes have a simple structure and low cost, which can reduce the cost and complexity of the optical lens frame 110 of this embodiment.

[0104] In some other optional embodiments, the guide vanes 23 are adjustable radial guide vanes.

[0105] The adjustable radial guide vanes can stably guide the airflow generated by the impeller 22 to the air supply channel 111, so that the airflow direction is changed from the direction generated by the rotation of the impeller 22 to a direction more suitable for entering the air supply channel 111. The adjustable radial guide vanes can adjust the direction of the guided airflow, and by adjusting the adjustable radial guide vanes, airflows of various flow rates can be guided. The adjustable radial guide vanes can increase the intelligence of the optical frame 110 of this embodiment.

[0106] Combination Figure 1 and Figure 2 As shown, in some embodiments, the optical lens frame 110 further includes a mounting ring 4 , which is disposed in the mounting cavity 321 and is threadedly connected to the fixing frame 3 , and the mounting ring 4 is used to mount the optical element 120 .

[0107] Through the threaded connection, the mounting ring 4 can be firmly connected to the fixing frame 3, thereby providing a stable support base for the optical element 120, so that the optical element 120 can maintain a fixed position in the frame, reduce the probability of displacement of the optical element 120 due to external factors such as vibration and collision, and improve the stability and reliability of the optical frame 110 of this embodiment.

[0108] The mounting ring 4 can accurately position the optical element 120 at the required position in the mounting cavity 321 of the fixing frame 3, ensure the relative position accuracy between the optical element 120 and other components in the optical lens frame 110 of this embodiment, and enable light to accurately pass through the optical element according to design requirements, thereby achieving good optical performance.

[0109] The threaded connection method makes the installation of the mounting ring 4 less difficult. When installing the mounting ring 4, the mounting ring 4 can be installed by screwing the mounting ring 4 into the corresponding thread on the fixing frame 3, which makes it convenient for the operator to quickly install the optical element 120 into the frame or quickly disassemble the optical element 120 from the frame, thereby improving the assembly efficiency and disassembly efficiency.

[0110] The mounting ring 4 can protect the edge of the optical element 120 , preventing the optical element 120 from being damaged by collision, scratching, etc. during installation and use, thereby extending the service life of the optical element 120 .

[0111] Combination Figure 1 and Figure 3 As shown, in some embodiments, the support rod 11 is movably disposed on the base 12 , and the base 12 is provided with an adjusting screw 5 , which is movably disposed and can abut against or separate from the support rod 11 .

[0112] When the position of the support rod 11 needs to be adjusted, the adjusting screw 5 is separated from the support rod 11, so that the position of the support rod 11 relative to the base 12 can be adjusted. After the position adjustment of the support rod 11 relative to the base 12 is completed, the adjusting screw 5 is brought into contact with the support rod 11, so that the movement of the support rod 11 is limited by the adjusting screw 5 to achieve the adjustment of the position of the support rod 11.

[0113] By rotating the adjusting screw, the height of the support rod 11 relative to the base 12 can be conveniently changed, so that the height of the optical element 120 can be adjusted so that the optical element 120 is in a suitable position.

[0114] Combination Figure 1 , Figure 2 and Figure 3 As shown, the optical device 100 of the embodiment of the present application includes: the optical lens frame 110 and the optical element 120 as described in the above embodiment, and the optical element 120 is installed in the installation cavity 321.

[0115] The optical device 100 of the embodiment of the present application includes the optical frame 110 as described in the above embodiment, and the support assembly 1 defines an air supply channel 111, so that the wind delivered by the air supply assembly 2 flows stably in the air supply channel 111, reducing air flow turbulence and energy loss. The guide cavity 311 of the fixed frame 3 is connected to the air supply channel 111, and the wind from the air supply channel 111 can be smoothly entered into the guide cavity 311 through the air inlet 312. The airflow can be rectified through the guide cavity 311, so that the wind blown out from the air outlet 322 is more uniform, reducing the probability of excessive or insufficient local wind speed, thereby facilitating uniform air cooling and heat dissipation of the optical element 120 in the installation cavity 321. After being guided and constrained by the guide cavity 311, the airflow flows to the air outlet 322 in a more orderly manner, and the airflow enters the installation cavity 321 through the air outlet 322, so as to be able to dissipate heat for the optical element 120 in the installation cavity 321.

[0116] The air flow velocity in the installation cavity 321 is relatively high, and the pressure in the installation cavity 321 is relatively low. There is a pressure difference between the inside and outside of the installation cavity 321, so that the air outside the installation cavity 321 is pressed into the installation cavity 321, thereby increasing the air flow intensity in the installation cavity 321, thereby increasing the heat dissipation effect of the optical element 120 in the installation cavity 321.

[0117] In addition, the support assembly 1, the air supply assembly 2 and the fixing frame 3 are connected to each other to form a relatively compact overall structure. Through the positional relationship between the support assembly 1, the air supply assembly 2 and the fixing frame 3, the air supply channel 111, the guide cavity 311 and the installation cavity 321 are integrated, so that the space can be efficiently utilized, and the volume of the optical frame 110 can be reduced, which is conducive to the miniaturization of the optical frame 110.

[0118] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
