[0002] In recent years, portable electronic devices have developed rapidly, such as smart electronic devices and tablet computers, which have become ubiquitous in modern life. Consequently, optical lens modules and optical reflection components mounted on these devices have also flourished. However, as technology advances, users' demands for the quality of optical reflection components are also increasing.

[0003] Specifically, optical lens modules employing deflection paths are becoming increasingly common.

[0101] This disclosure provides an optical reflection assembly, comprising a reflective element, a reflective element holder, and a structural component. The reflective element includes a reflective surface, through which light rays are incident and deflected. The reflective element holder includes a mounting surface corresponding to the reflective element. The structural component is made of metal and has a three-dimensional structure. At least a portion of the structural component is embedded in the reflective element holder, and the structural component includes a first support wall, a second support wall, and at least one extending wall. The first and second support walls are bent to form a first fold line at an angle, and the extending wall is bent to form an extended fold line, which is not closed. The angle between the first and second support walls after bending is θ. S When viewed along one direction, the projections of the reflecting element and the structural component overlap, and the minimum distance between the reflecting element and the structural component along that direction is D. R It satisfies the following condition: 90 degrees ≤ θS ≤164 degrees; and 0.05 mm <D R <1.8mm.

[0102] By embedding structural components, the rigidity of the reflective element holder can be improved, enabling the reflective element holder to maintain its structure and dimensional accuracy when subjected to external impact, or to increase the bearing force during assembly and improve assembly reliability.

[0103] The first fold line and the extended fold line can make the structural components three-dimensional, thereby bearing stress in different directions and improving the rigidity of the overall structure.

[0104] The structural components can also suppress the volume change of the reflective element holder when the temperature changes, and reduce the relative displacement between the reflective element holder and the reflective element. The temperature change may come from the ambient temperature or the heat source generated by the light source.

[0105] When 0.05mm is met <D R When the thickness is less than 1.8mm, it can provide better protection for the reflective element, so as to avoid deformation of the reflective element holder when subjected to stress, and to avoid reducing the assembly accuracy of the reflective element or squeezing the reflective element.

[0106] The angle between the first and second support walls after bending depends on the structure of the reflective element retainer. Therefore, when 90 degrees ≤ θ S When the angle is ≤164 degrees, it is used to cooperate with the structure of the reflective element retainer and can withstand external force impacts from different directions.

[0107] Specifically, the non-closed line is a line segment open at both ends. The first fold line and the extended fold line are not decorative lines on the structural component, but rather creases formed at the bends during the stamping of the metal sheet. Furthermore, the first fold line and the extended fold line can be rounded corners, and the radius of curvature of the rounded corners is related to the angle of the bend.

[0108] Furthermore, the reflective element can be made of a brittle material, such as glass, polystyrene (PS), polycarbonate (PC), polymethyl methacrylate (PMMA), etc., but is not limited to these. Because the reflective element requires a high degree of flatness on the mounting surface, structural components are needed to maintain this flatness.

[0109] Metal structural components have a high Young's modulus, resulting in less deformation under stress. The metal surface can undergo surface treatments such as roughening or blackening. Roughening improves the bonding strength between the plastic and metal materials, while blackening reduces light reflectivity. Specifically, the structural component can be manufactured from a 0.15mm thick metal sheet through a stamping process, and the metal sheet material can be stainless steel, aluminum, aluminum alloy, etc., and is not limited to these.

[0110] The structural component and the reflective element holder can be integrally molded. Specifically, the structural component and the reflective element holder can be integrally molded by embedding or injection molding.

[0111] The reflective element holder may include two light-transmitting holes through which light passes, and the geometrical central axes of the light-transmitting holes do not overlap. Specifically, the light-transmitting holes of the reflective element holder may be eccentrically or angled; however, such arrangements can easily reduce structural strength. It must be noted that the reflective element holder has a complex shape, and mass production can utilize plastic injection molding processes; however, the complex shape can easily reduce structural strength and cause warping. Therefore, embedding an injection-molded structural component can improve structural rigidity and prevent deformation of the reflective element holder.

[0112] The length of the extended fold line can be shorter than the length of the first fold line. Specifically, the extended wall serves to assist in supporting and protecting the reflective element. It extends by partially bending from the edge of the first or second support wall. A shorter extended fold line allows the extended wall to accommodate the complex shape of the reflective element. Specifically, the first fold line can be a straight line or a curve.

[0113] Extending a broken line can result in a straight line. This can improve mass production manufacturability.

[0114] The number of extension walls can be at least two, and the reflective element can further include an incident surface, an exiting surface, and two connecting surfaces. The incident surface and the exiting surface allow light to enter and exit the reflective element, respectively. The connecting surfaces connect the incident surface, the exiting surface, and the reflective surface. Each extension wall includes a plane, and each plane is correspondingly arranged with each connecting surface. In this way, the protection of the reflective element can be enhanced through the extension walls.

[0115] The extension walls can be arranged symmetrically. This makes the structure more stable.

[0116] The structural component may include multiple through holes, and the through holes penetrate at least one of the first support wall, the second support wall, and the extension wall. This improves the quality of injection molding, increases the bonding strength between the plastic and the metal, and also allows for a lighter structural component.

[0117] The reflective element holder may further include a injection port, and the structural component may further include an exposed portion, wherein the exposed portion is exposed outside the reflective element holder, and the injection port is disposed adjacent to the exposed portion. Therefore, the above-described arrangement can improve injection molding quality and facilitate mass production.

[0118] The volume proportion of the structural component embedded in the reflective element retainer can account for more than 90% of the overall volume of the structural component. This can further improve the structural rigidity of the reflective element retainer.

[0119] The structural component may not protrude from the surface of the reflective element holder. This avoids interference between the structural component and other components.

[0120] The reflective element can be a glass reflective element. It must be noted that glass reflective elements are made of brittle materials and are easily broken when subjected to external impact, therefore structural protection is required. Furthermore, reflective elements can also be made of plastic with a reflective layer coated on the surface, and are not limited to this.

[0121] The angle between the extended wall and the second support wall after bending is θ. E It can satisfy the following condition: 90 degrees ≤ θ E ≤152 degrees. Therefore, when 90 degrees ≤ θ is satisfied. E When the angle is ≤152 degrees, the shape of the reflective element retainer can be locally extended to improve the impact resistance of the structural components.

[0122] The various technical features in the optical reflection component disclosed herein can be combined and configured to achieve the corresponding effects.

[0123] This disclosure provides an optical lens module comprising the aforementioned optical reflection component and a lens assembly. The lens assembly includes multiple lenses, and an optical axis passes through the lenses, wherein each lens may include at least one glass lens. The reflection element holder further includes a lens holding portion for assembling and fixing the lens assembly. Specifically, the lens holding portion can directly assemble the lens assembly or indirectly assemble the lens assembly through a lens barrel, and the glass lens can withstand high temperature and high humidity environments.

[0124] This disclosure provides an electronic device that includes the aforementioned optical reflective component.

[0125] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.

[0126] <First Embodiment>

[0127] Please refer to Figures 1A to 1D ,in Figure 1A A perspective view of the optical lens module 100 according to the first embodiment of this disclosure is shown. Figure 1B Drawing according to Figure 1A A partial exploded view of the optical lens module 100 in the first embodiment. Figure 1C Drawing according to Figure 1A A side cross-sectional view of the optical lens module 100 in the first embodiment. Figure 1D Drawing according to Figure 1A A top perspective view of the optical lens module 100 in the first embodiment. Figures 1A to 1DAs can be seen, the optical lens module 100 includes an optical reflection component (not shown in the figure), a first lens group 111 and a second lens group 112, and has a first optical axis X1 and a second optical axis X2.

[0128] Please refer to Figure 1E and Figure 1F ,in Figure 1E Drawing according to Figure 1A A perspective view of the optical reflection component in the first embodiment. Figure 1F Drawing according to Figure 1E A partial cross-sectional view of the optical reflection component along section line 1F-1F in the first embodiment. Figures 1A to 1F As can be seen, the optical reflection assembly includes a reflective element 120, a reflective element holder 130, and a structural member 140. The reflective element holder 130 is correspondingly disposed with the reflective element 120, and at least a portion of the structural member 140 is embedded in the reflective element holder 130. The structural member 140 and the reflective element holder 130 can be integrally formed by embedding and injection molding. By embedding the structural member 140, the rigidity of the reflective element holder 130 can be improved, enabling the reflective element holder 130 to maintain its structure and dimensional accuracy when subjected to external impact, or to increase the bearing force during assembly, thereby improving assembly reliability. Furthermore, the structural member 140 can also suppress the volume change of the reflective element holder 130 during temperature changes, reducing the relative displacement between the reflective element holder 130 and the reflective element 120, wherein the temperature change may originate from the ambient temperature or a heat source generated by the light source.

[0129] Depend on Figure 1C As can be seen, a ray of light (not shown) enters the first lens group 111 along the first optical axis X1, and the reflecting element 120 reflects the ray so that it enters the second lens group 112 along the second optical axis X2. Specifically, the first lens group 111 and the second lens group 112 each include multiple lenses (not shown), wherein the first optical axis X1 passes through the lens of the first lens group 111, and the second optical axis X2 passes through the lens of the second lens group 112. Furthermore, the lens includes at least one glass lens, which can withstand high temperature and high humidity environments.

[0130] Depend on Figure 1B and Figure 1CAs can be seen, the reflective element 120 includes a reflective surface 121, a light-incident surface 122, a light-emitting surface 123, and two connecting surfaces 124. Light is incident on the reflective surface 121 and deflected by it. The light-incident surface 122 and the light-emitting surface 123 respectively allow light to enter and exit the reflective element 120. The connecting surfaces 124 connect the light-incident surface 122, the light-emitting surface 123, and the reflective surface 121. Specifically, the reflective element 120 can be made of a brittle material, or it can be made of plastic with a reflective layer coated on its surface. The brittle material can be glass, PS, PC, PMMA, etc., but is not limited to these. Because brittle materials such as glass are easily broken by external impact, the reflective element 120 requires the protection of the structural component 140. In the first embodiment, the reflective element 120 has one reflective surface 121.

[0131] Depend on Figures 1A to 1C As can be seen, the reflective element holder 130 includes a lens holder 131 and a mounting surface 132, wherein the lens holder 131 is used to assemble and fix the first lens group 111 and the second lens group 112, and the mounting surface 132 is correspondingly disposed with the reflective element 120. It must be noted that since the reflective element 120 has high requirements for the flatness of the mounting surface 132, the structural component 140 is required to maintain the flatness. In the first embodiment, the lens holder 131 directly assembles the second lens group 112, and indirectly assembles the first lens group 111 through a lens barrel (not shown in the figure).

[0132] Depend on Figure 1C and Figure 1D It is known that the volume ratio of the structural component 140 embedded in the reflective element holder 130 accounts for more than 90% of the overall volume of the structural component 140, and the structural component 140 does not protrude from the surface of the reflective element holder 130. In this way, the structural rigidity of the reflective element holder 130 can be further improved, and interference between the structural component 140 and other components can be avoided.

[0133] Depend on Figure 1B and Figure 1C It is understood that the reflective element holder 130 includes two light-transmitting holes 133 through which light passes, and the geometric central axes of the light-transmitting holes 133 do not overlap. The light-transmitting holes 133 of the reflective element holder 130 can be eccentrically or angled; however, such arrangements can easily reduce structural strength. It must be noted that the reflective element holder 130 has a complex shape. Mass production can utilize plastic injection molding; however, the complex shape can easily reduce structural strength and cause warping. Therefore, embedding the injection-molded structural member 140 can improve structural rigidity and prevent deformation of the reflective element holder 130.

[0134] Please refer to Figure 1G and Figure 1H ,in Figure 1G Drawing according to Figure 1A A perspective view of structural member 140 in the first embodiment. Figure 1H Drawing according to Figure 1A A perspective view of structural member 140 in the first embodiment. Figure 1G and Figure 1H It is understood that the structural component 140 is made of metal and has a three-dimensional structure, including a first supporting wall 141, a second supporting wall 142, and at least one extending wall 143. The first supporting wall 141 and the second supporting wall 142 are bent together to form a first fold line 144 at an angle. The extending wall 143 and the second supporting wall 142 are bent together to form an extending fold line 145, and the extending fold line 145 is not a closed line. Through the first fold line 144 and the extending fold line 145, the structural component 140 can have a three-dimensional structure, thereby bearing stress in different directions and improving the rigidity of the overall structure. In the first embodiment, the number of extending walls 143 is two. It must be noted that... Figure 1A , Figure 1B and Figures 1E to 1H Two-point chain lines are used to represent the edge tangents at the intersection of curved surfaces.

[0135] The structural component 140, made of metal, has a high Young's modulus, resulting in minimal deformation under stress. The metal surface can undergo surface treatments such as roughening or blackening. Roughening improves the bonding strength between the plastic and metal materials, while blackening reduces light reflectivity. Specifically, the structural component 140 can be manufactured from a 0.15mm thick metal sheet through a stamping process, and the metal sheet material can be stainless steel, aluminum, aluminum alloy, etc., and is not limited to these.

[0136] Specifically, the non-closed line is a line segment open at both ends, and the first fold line 144 and the extended fold line 145 are not decorative lines on the structural component 140, but rather creases formed at the bends during the stamping of the metal sheet. Furthermore, the first fold line 144 and the extended fold line 145 can be rounded corners, and the radius of curvature of the rounded corners is related to the angle of the bend.

[0137] Depend on Figure 1G It can be seen that the length of the extending fold line 145 can be less than the length of the first fold line 144, where the first fold line 144 can be a straight line or a curve, while the extending fold line 145 can be a straight line. Specifically, the extending wall 143 serves to assist in supporting and protecting the reflective element 120, extending by a partial bend from the edge of the first support wall 141 or the second support wall 142. The shorter extending fold line 145 allows the extending wall 143 to accommodate the complex shape of the reflective element retainer 130. Furthermore, the straight extending fold line 145 improves manufacturability for mass production.

[0138] Depend on Figure 1FAs can be seen, each of the extension walls 143 includes a plane (not shown in the figure), and each plane is correspondingly arranged with each connecting surface 124, wherein the extension walls 143 are symmetrically arranged. In this way, the protection of the reflective element 120 can be strengthened through the extension walls 143, and the structural component 140 can be made more stable.

[0139] Depend on Figure 1C and Figure 1D It can be seen that when viewed along one direction D1, the projections of the reflective element 120 and the structural member 140 overlap, and are caused by... Figure 1C It can be seen that the projection of the reflective element 120 overlaps with that of the extension wall 143 of the structural component 140.

[0140] Depend on Figure 1D and Figure 1H It can be seen that the angle between the first support wall 141 and the second support wall 142 after bending is θ. S The minimum distance between the reflective element 120 and the structural component 140 in direction D1 is D.

[0142] <Second Embodiment>

[0143] Please refer to Figure 2 The diagram illustrates a perspective view of structural member 240 according to the second embodiment of this disclosure. Figure 2 It is understood that the structural component 240 is made of metal and has a three-dimensional structure, including a first supporting wall 241, a second supporting wall 242, and at least one extending wall 243. The first supporting wall 241 and the second supporting wall 242 are bent together to form a first fold line 244 at an angle. The extending wall 243 and the second supporting wall 242 are bent together to form an extending fold line 245, and the extending fold line 245 is not a closed line. Through the first fold line 244 and the extending fold line 245, the structural component 240 can have a three-dimensional structure, thereby bearing stress in different directions and improving the rigidity of the overall structure. In the second embodiment, the number of extending walls 243 is two.

[0144] Furthermore, the structural component 240 includes a plurality of through holes 246, which penetrate the first support wall 241, and the shape of the through holes 246 is not limited thereto. This improves the quality of injection molding, increases the bonding strength between the plastic and the metal, and also makes the structural component 240 lighter.

[0145] It should be noted that the structural component 240 of the second embodiment can be applied to the optical lens module 100 of the first embodiment, but is not limited thereto.

[0146] Furthermore, the structure and configuration of the remaining components in the second embodiment are the same as those in the first embodiment, and will not be described again here.

[0147] <Third Embodiment>

[0148] Please refer to Figures 3A to 3C ,in Figure 3A A perspective view of the optical lens module 300 according to the third embodiment of this disclosure is shown. Figure 3B Drawing according to Figure 3A An exploded view of the optical lens module 300 in the third embodiment. Figure 3C Drawing according to Figure 3A A side cross-sectional view of the optical lens module 300 in the third embodiment. Figures 3A to 3C As can be seen, the optical lens module 300 includes an optical reflection component (not shown in the figure) and a lens group 310.

[0149] Please refer to Figures 3D to 3F ,in Figure 3D Drawing according to Figure 3A A perspective view of the optical reflection component in the third embodiment. Figure 3E Drawing according to Figure 3D A partial cross-sectional view of the optical reflection component along section line 3E-3E in the third embodiment. Figure 3F Drawing according to Figure 3D Another partial cross-sectional view of the optical reflection component along section line 3E-3E in the third embodiment. Figures 3A to 3F As can be seen, the optical reflection assembly includes reflective elements 320a and 320b, reflective element holders 330a and 330b, and a structural member 340. The reflective element holders 330a and 330b are correspondingly disposed with respect to the reflective elements 320a and 320b, respectively. At least a portion of the structural member 340 is embedded in the reflective element holder 330b, and the structural member 340 and the reflective element holder 330b can be integrally formed by injection molding. Embedding the structural member 340 can improve the rigidity of the reflective element holder 330b, enabling it to maintain its structure and dimensional accuracy when subjected to external impact, or increasing the bearing capacity during assembly and improving assembly reliability. Furthermore, the structural member 340 can also suppress volume changes in the reflective element holder 330b due to temperature variations, reducing the relative displacement between the reflective element holder 330b and the reflective elements 320b. These temperature changes may originate from ambient temperature or heat generated by a light source.

[0150] Lens group 310 includes multiple lenses (not shown in the figure), one optical axis (not shown in the figure) passes through the lenses of lens group 310, and lens group 310 is disposed between reflective elements 320a and 320b. Furthermore, the lens includes at least one glass lens, which can withstand high temperature and high humidity environments.

[0151] Depend on Figure 3B As can be seen, reflective elements 320a and 320b each include a reflective surface 321, a light-incident surface 322, a light-emitting surface 323, and two connecting surfaces 324 (taking the labeling of reflective element 320b as an example). Light enters through the reflective surface 321 and is deflected by it. The light-incident surface 322 and the light-emitting surface 323 allow light to enter and exit reflective elements 320a and 320b respectively. The connecting surfaces 324 connect the light-incident surface 322, the light-emitting surface 323, and the reflective surface 321. Specifically, reflective elements 320a and 320b can be made of brittle materials, or they can be made of plastic with a reflective layer coated on the surface. Brittle materials can include glass, PS, PC, PMMA, etc., but are not limited to these. Because brittle materials such as glass are easily broken by external impact, reflective elements 320a and 320b require protection from structural component 340. In the third embodiment, the number of reflective surfaces 321 of reflective elements 320a and 320b is one each.

[0152] Depend on Figure 3C As can be seen, the reflective element holders 330a and 330b include a lens holding portion (not shown in the figure), and the reflective element holders 330a and 330b respectively include a mounting surface 332a and 332b. The lens holding portion is used to assemble and fix the lens assembly 310, and the mounting surface 332a is correspondingly provided with the reflective element 320a, and the mounting surface 332b is correspondingly provided with the reflective element 320b. It must be noted that since the reflective elements 320a and 320b have high requirements for the flatness of the mounting surfaces 332a and 332b, the structural component 340 is required to maintain the flatness.

[0153] Specifically, the reflective element holders 330a and 330b each include two light-transmitting holes 333 (taking the designation of the reflective element holder 330a as an example), a light ray (not shown in the figure) passes through the light-transmitting hole 333, and the geometric central axes of the light-transmitting holes 333 do not overlap with each other.

[0154] Depend on Figure 3C It is known that the volume ratio of the structural component 340 embedded in the reflective element holder 330b accounts for more than 90% of the overall volume of the structural component 340, and the structural component 340 does not protrude from the surface of the reflective element holder 330b. This further enhances the structural rigidity of the reflective element holder 330b and avoids interference between the structural component 340 and other components.

[0155] Please refer to Figures 3G to 3I ,in Figure 3G Drawing according to Figure 3A A perspective view of structural component 340 in the third embodiment. Figure 3H Drawing according to Figure 3A Side view of structural member 340 in the third embodiment. Figure 3I Drawing according to Figure 3A Front view of structural member 340 in the third embodiment. (From...) Figures 3G to 3I It is understood that the structural component 340 is made of metal and has a three-dimensional structure, including a first supporting wall 341, a second supporting wall 342, and at least one extending wall 343. The first supporting wall 341 and the second supporting wall 342 are bent together to form a first fold line 344 at an angle. The extending wall 343 and the second supporting wall 342 are bent together to form an extending fold line 345, and the extending fold line 345 is not a closed line. The first fold line 344 and the extending fold line 345 enable the structural component 340 to have a three-dimensional structure, thereby bearing stress in different directions and improving the overall structural rigidity. In the third embodiment, the number of extending walls 343 is three.

[0156] The structural component 340, made of metal, has a high Young's modulus, resulting in minimal deformation under stress. The metal surface can undergo surface treatments such as roughening or blackening. Roughening improves the bonding strength between the plastic and metal materials, while blackening reduces light reflectivity. Specifically, the structural component 340 can be manufactured from a 0.15mm thick metal sheet through a stamping process, and the metal sheet material can be stainless steel, aluminum, aluminum alloy, etc., and is not limited to these.

[0157] Specifically, the non-closed line is a line segment open at both ends, and the first fold line 344 and the extended fold line 345 are not decorative lines on the structural component 340, but rather creases formed at the bends during the stamping of the metal sheet. Furthermore, the first fold line 344 and the extended fold line 345 can be rounded corners, and the radius of curvature of the rounded corners is related to the angle of the bend.

[0158] Depend on Figure 3G It can be seen that the length of the extending fold line 345 can be less than the length of the first fold line 344, where the first fold line 344 can be a straight line or a curve, while the extending fold line 345 can be a straight line. Specifically, the extending wall 343 serves to assist in supporting and protecting the reflective element 320b, extending by a partial bend from the edge of the first support wall 341 or the second support wall 342. The shorter extending fold line 345 allows the extending wall 343 to accommodate the complex shape of the reflective element retainer 330b. Furthermore, the straight extending fold line 345 improves manufacturability for mass production.

[0159] Depend on Figure 3C , Figure 3H and Figure 3IIt can be seen that the angle between the first support wall 341 and the second support wall 342 after bending is θ. S When viewed along direction D1, the projections of the reflective element 320b and the structural component 340 overlap, and the minimum distance between the reflective element 320b and the structural component 340 along direction D1 is D. R The angle between the extended wall 343 and the second support wall 342 after bending is θ. E The parameters satisfy the conditions in Table 2 below.

[0160]

[0161] Furthermore, the structure and configuration of the remaining components in the third embodiment are the same as those in the first embodiment, and will not be described again here.

[0162] <Fourth Embodiment>

[0163] Please refer to Figure 4 The diagram illustrates a perspective view of structural member 440 according to the fourth embodiment of this disclosure. Figure 4 It is understood that the structural component 440 is made of metal and has a three-dimensional structure, including a first supporting wall 441, a second supporting wall 442, and at least one extending wall 443. The first supporting wall 441 and the second supporting wall 442 are bent together to form a first fold line 444 at an angle. The extending wall 443 and the second supporting wall 442 are bent together to form an extending fold line 445, and the extending fold line 445 is not a closed line. The first fold line 444 and the extending fold line 445 enable the structural component 440 to have a three-dimensional structure, thereby bearing stress in different directions and improving the overall structural rigidity. In the fourth embodiment, the number of extending walls 443 is three.

[0164] Furthermore, structural component 440 includes multiple through holes 446, which penetrate the second support wall 442 and the extension wall 443, and the shape of the through holes 446 is not limited thereto. This improves the quality of injection molding, increases the bonding strength between the plastic and the metal, and also makes structural component 440 lighter.

[0165] It should be noted that the structural component 440 of the fourth embodiment can be applied to the optical lens module 300 of the third embodiment, but is not limited thereto.

[0166] Furthermore, the structure and configuration of the remaining components in the fourth embodiment are the same as those in the first and third embodiments, and will not be described again here.

Figures 5A to 5E As can be seen, the optical reflection assembly includes a reflective element 520, a reflective element holder 530, and a structural member 540. The reflective element holder 530 is correspondingly disposed with the reflective element 520, and at least a portion of the structural member 540 is embedded in the reflective element holder 530. The structural member 540 and the reflective element holder 530 can be integrally formed by embedding and injection molding. By embedding the structural member 540, the rigidity of the reflective element holder 530 can be improved, enabling the reflective element holder 530 to maintain its structure and dimensional accuracy when subjected to external impact, or to increase the bearing force during assembly, thereby improving assembly reliability. Furthermore, the structural member 540 can also suppress the volume change of the reflective element holder 530 during temperature changes, reducing the relative displacement between the reflective element holder 530 and the reflective element 520, wherein the temperature change may originate from ambient temperature or heat generated by the light source.

[0170] Lens group 510 includes multiple lenses (not shown in the figure), one optical axis (not shown in the figure) passing through the lenses of lens group 510. Furthermore, the lens includes at least one glass lens, which can withstand high temperature and high humidity environments.

Light rays are incident on the reflective surface 521 and deflected by it. The light-incident surface 522 and the light-exiting surface 523 respectively allow light rays to enter and exit the reflective element 520. The connecting surfaces 524 connect the light-incident surface 522, the light-exiting surface 523, and the reflective surface 521. Specifically, the reflective element 520 can be made of a brittle material, or it can be made of plastic with a reflective layer coated on its surface. The brittle material can be glass, PS, PC, PMMA, etc., but is not limited to these. Because brittle materials such as glass are easily broken by external impact, the reflective element 520 requires the protection of the structural component 540. In the fifth embodiment, the reflective element 520 is composed of multiple prisms, and the number of reflective surfaces 521 in the reflective element 520 is four.

[0172] Depend on Figure 5B , Figure 5D and Figure 5E It is understood that the reflective element holder 530 includes a lens holder portion 531, and the reflective element holder 530 includes a mounting surface 532 and a fixing member 534. The lens holder portion 531 is used to assemble and fix the lens assembly 510, the mounting surface 532 is correspondingly disposed with the reflective element 520, and the fixing member 534 is used to fix the reflective element 520. It must be noted that since the reflective element 520 has high requirements for the flatness of the mounting surface 532, the structural member 540 is required to maintain the flatness. In the fifth embodiment, the lens holder portion 531 indirectly assembles the lens assembly 510 through a lens barrel 550, or the lens holder portion 531 and the lens barrel 550 can be integrally formed, so that the lens holder portion 531 can directly assemble the lens assembly 510.

[0173] Depend on Figure 5B and Figure 5C It can be seen that the reflective element holder 530 includes two light-transmitting holes 533, through which a light ray (not shown) passes, and the geometric central axes of the light-transmitting holes 533 do not overlap with each other.

[0174] Depend on Figure 5C It is known that the volume ratio of the structural component 540 embedded in the reflective element holder 530 accounts for more than 90% of the overall volume of the structural component 540, and the structural component 540 does not protrude from the surface of the reflective element holder 530. This further enhances the structural rigidity of the reflective element holder 530 and avoids interference between the structural component 540 and other components.

The metal surface can undergo surface treatments such as roughening or blackening. Roughening improves the bonding strength between the plastic and metal materials, while blackening reduces light reflectivity. Specifically, the structural component 540 can be manufactured from a 0.15mm thick metal sheet through a stamping process, and the metal sheet material can be stainless steel, aluminum, aluminum alloy, etc., and is not limited to these.

[0177] Specifically, the non-closed line is a line segment open at both ends, and the first fold line 544 and the extended fold line 545 are not decorative lines on the structural component 540, but rather creases formed at the bends during the stamping of the metal sheet. Furthermore, the first fold line 544 and the extended fold line 545 can be rounded corners, and the radius of curvature of the rounded corners is related to the angle of the bend.

[0178] Depend on Figure 5F It can be seen that the length of the extending fold line 545 can be less than the length of the first fold line 544, where the first fold line 544 can be a straight line or a curve, while the extending fold line 545 can be a straight line.
