Description

Technical Field

[0001] This disclosure relates to an optical module. Background Technology

[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards convenient and thinner designs to provide users with more choices.

[0003] The aforementioned electronic devices with photographic or video recording functions typically include an optical module to drive optical elements (such as a lens) along the optical axis, thereby achieving autofocus (AF) or optical image stabilization (OIS). Light can pass through the aforementioned optical elements and form an image on the photosensitive element. However, the current trend in mobile devices is towards smaller size and higher durability; therefore, effectively reducing the size of the optical module and improving its durability has become an important issue.

[0093] The following discloses many different implementations or examples to carry out the different features provided. Specific embodiments of the elements and their arrangements are described below to illustrate this disclosure. Of course, these embodiments are merely illustrative and should not be construed as limiting the scope of this disclosure. For example, the specification mentions that a first feature is formed on a second feature. This may include embodiments where the first and second feature are in direct contact, or embodiments where there are other features between the first and second feature; in other words, the first and second feature are not in direct contact.

[0094] Furthermore, repeated reference numerals or designations may be used in different embodiments. These repetitions are merely for the purpose of clearly and simply describing this disclosure and do not represent a specific relationship between the different embodiments and / or structures discussed. Additionally, the formation, connection, and / or coupling to another feature component in this disclosure may include embodiments in which the feature components are formed in direct contact, and may also include embodiments in which additional feature components may be formed to insert into the aforementioned feature component, such that the aforementioned feature components may not be in direct contact. Furthermore, spatially related terms such as “vertical,” “above,” “up,” “below,” “bottom,” and similar terms (e.g., “downward,” “upward,” etc.) may be used to facilitate the description of the relationship between one element(s) or feature(s) in the illustrations and another element(s) or feature(s). These spatially related terms are intended to cover different orientations of the device including the feature.

[0095] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the background or context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0096] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify elements of the claims does not imply or represent any prior ordinal number for the claimed element, nor does it represent the order of one claimed element with another, or the order of manufacturing methods. The use of multiple ordinal numbers is only to enable a claimed element with a certain name to be clearly distinguished from another claimed element with the same name.

[0097] Furthermore, in some embodiments of this disclosure, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or they may refer to two structures that are not in direct contact, with other structures disposed between them. Moreover, these terms regarding joining and connection may also include cases where both structures are movable or both structures are fixed.

[0098] First, please refer to Figure 1A The diagram illustrates an optical module 1001 according to some embodiments of the present disclosure. The optical module 1001 may primarily include a light intensity adjustment mechanism 1100 and an optical element driving mechanism 1200. An optical element 1230 may be disposed in the optical element driving mechanism 1200, and the optical element 1230 may be driven by the optical element driving mechanism 1200 to achieve optical image stabilization (OIS) or autofocus (AF) functions. The light intensity adjustment mechanism 1100 may be disposed on the optical element driving mechanism 1200 to control the total amount or characteristics of light incident on the optical element 1230. For example, the light intensity adjustment mechanism 1100 may serve as an aperture to control the depth of field, image quality, and light intake of the optical element 1230.

[0099] In some embodiments, the optical element 1230 may include, for example, a lens, mirror, prism, beam splitter, aperture, liquid lens, image sensor, camera module, ranging module, etc. It should be noted that the definition of optical element here is not limited to elements related to visible light; elements related to invisible light (e.g., infrared light, ultraviolet light) may also be included in this invention. For example, when the optical element 1230 is a lens, it may include a lens barrel 1231 and at least one lens element 1232. In some embodiments, the material of the lens barrel 1231 may include a non-metallic material, and the thermal conductivity of the lens barrel 1231 may differ from that of the support 1220; for example, the thermal conductivity of the lens barrel 1231 may be higher than that of the support 1220.

[0100] Figure 2A This is a schematic diagram of the light intensity adjustment mechanism 1100. Figure 2B This is an exploded view of the light intensity adjustment mechanism 1100. (See diagram below.) Figure 1A , Figure 2A as well as Figure 2B As shown, the light intensity adjustment mechanism 1100 mainly includes an outer frame 1111, a base 1112, a top plate 1113, a movable part 1120, a light intensity control element 1140, a first drive assembly 1150, a third elastic element 1160, a connecting element 1162, a magnetically conductive element 1164, and a position sensing element 1166, all arranged on the main shaft 1500. The outer frame 1111, base 1112, and top plate 1113 can be collectively referred to as the fixing part 1110. The light intensity control element 1140 may include a first light intensity control unit 1141, a second light intensity control unit 1142, a third light intensity control unit 1143, and a fourth light intensity control unit 1144, or may include light intensity control elements such as blades, polarizers, and filters. The outer frame 1111 and the base 1112 form a first receiving space 1130 for accommodating components such as the movable part 1120, the third elastic element 1160, the connecting element 1162, the magnetically conductive element 1164, and the position sensing element 1166. In some embodiments, the base 1112 is closer to the optical element 1230 than the outer frame 1111. The light intensity control element 1140 may be located outside the first receiving space 1130.

[0101] The movable part 1120 can be connected to the light intensity control element 1140 and can move relative to the fixed part 1110, for example, it can be movably connected to the base 1112 via the connecting element 1162. The first drive assembly 1150 can be used to drive the movable part 1120 to move relative to the fixed part 1110. For example, the first drive assembly 1150 may include a first drive element 1151 and a second drive element 1152, respectively disposed on the movable part 1120 and the fixed part 1110 (e.g., the base 1112). The first drive element 1151 and the second drive element 1152 may be, for example, a combination of a magnet and a coil, to generate a driving force to drive the movable part 1120 to move relative to the fixed part 1110. In some embodiments, the first drive assembly 1150 may also include a piezoelectric element, a shape memory alloy, or other drive element. The magnetic guiding element 1164 can be used to guide the direction of the magnetic field of the first drive element 1151. In some embodiments, such as Figure 1A , Figure 2B As shown, the first driving element 1151 and the second driving element 1152 can be arranged along the direction of the main shaft 1500, and the magnetic element 1164 and the first driving element 1151 can also be arranged along the direction of the main shaft 1500.

[0102] The position sensing element 1166 can be used to sense changes in the magnetic field when the first driving element 1151 moves, so as to obtain the position of the moving part 1120 relative to the fixed part 1110. For example, the aforementioned position sensing element 1166 may include a Hall sensor, a magnetoresistive effect sensor (MRSensor), a giant magnetoresistive effect sensor (GMR Sensor), a tunneling magnetoresistive effect sensor (TMR Sensor), or a fluxgate sensor.

[0103] In some embodiments, the optical element driving mechanism 1200 may mainly include a housing 1211, a base 1212, a carrier 1220, and a second driving assembly 1240. The housing 1211 and the base 1212 may be fixed to each other to form the housing of the optical element driving mechanism 1200 to accommodate other components. The carrier 1220 may move relative to the housing 1211 and the base 1212 and may be used to connect the optical element 1230.

[0104] The second drive assembly 1240 may include a third drive element 1241 and a fourth drive element 1242, respectively disposed on the support 1220 and the housing 1211. The third drive element 1241 and the fourth drive element 1242 may be, for example, a combination of a magnet and a coil, used to generate a driving force to drive the support 1220 to move relative to the housing 1211. In some embodiments, the second drive assembly 1240 may also include a piezoelectric element, a shape memory alloy, or other drive element.

[0105] In some embodiments, the support 1220 can be suspended in the second receiving space 1260 formed by the housing 1211 and the base 1212 via the first elastic element 1251 and the second elastic element 1252. Thus, the support 1220 can be movably connected to the housing 1211 via the first elastic element 1251 and the second elastic element 1252.

[0106] In some embodiments, heat is generated when the first drive assembly 1150 drives the movable part 1120 to move relative to the fixed part 1110. However, excess heat may affect the image quality of the optical element 1230. Therefore, a thermal control assembly 1300 can be provided in the optical module 1001 to adjust the temperature of the optical element 1230, thereby improving the image quality. In some embodiments, the thermal control assembly 1300 may correspond to the optical element 1230 or the carrier 1220, and may include a first thermal control element 1311 and a second thermal control element 1320.

[0107] Figure 1B yes Figure 1A A schematic diagram of some components is shown. For example, the first thermal control element 1311 may have a heat insulation effect and may be disposed between the light intensity adjustment mechanism 1100 and the optical element driving mechanism 1200, for example, between the optical element 1230 and the light intensity adjustment mechanism 1100, in order to isolate the heat generated by the first driving component 1150 (heat source) from being conducted to the optical element 1230.

[0108] The second thermal control element 1320 may have a heat-conducting or heat-dissipating effect to conduct heat generated by the first drive assembly 1150 (heat source) away from the optical element 1230. In some embodiments, the material of the second thermal control element 1320 may include metal, while the material of the base 1112 may not include metal, for example, it may include a non-metallic material (plastic, rubber, etc.). For example, the second thermal control element 1320 may be fixedly disposed in the fixing portion 1110, for example, it may be embedded in the base 1112 and exposed on the first surface 1116 of the base 1112 facing away from the optical element 1230, and not exposed on the second surface 1117 of the base 1112 facing the optical element 1230. In some embodiments, the second thermal control element 1320 may be connected to the outer frame 1111, and the material of the outer frame 1111 may include metal, so that the heat generated by the first drive assembly 1150 can be transferred to the outer frame 1111 via the second thermal control element 1320 for heat dissipation through the outer frame 1111, which includes a metallic material. Furthermore, in some embodiments, by exposing the second thermal control element 1320 to the base 1112, heat can be further dissipated from the portion of the second thermal control element 1320 exposed to the base 1112, thereby preventing the heat generated by the first drive assembly 1150 from affecting the operation of the first optical element 1230.

[0109] In some embodiments, the thermal conductivity of the first thermal control element 1311 is lower than that of the second thermal control element 1320, the thermal conductivity of the base 1112 is lower than that of the outer frame 1111, and the thermal conductivity of the second thermal control element 1320 is higher than that of the outer frame 1111. In some embodiments, the first thermal control element 1311 is closer to the optical element 1230 than the second thermal control element 1320, and the first thermal control element 1311 is located between the optical element 1230 and the second thermal control element 1320.

[0110] In some embodiments, the carrier 1220 and the optical element 1230 can be connected via the first adhesive element 1400. For example, such as Figure 1A , Figure 1B As shown, the first adhesive element 1400 can directly contact the carrier 1220 and the optical element 1230, and the first adhesive element 1400 may include a non-metallic material (e.g., plastic, rubber, etc.). In some embodiments, the first thermal control element 1311 may also be referred to as the second adhesive element, and the second thermal control element 1320 is (indirectly) connected to the optical element 1230 via the first thermal control element 1311. In some embodiments, the materials of the first thermal control element 1311 and the first adhesive element 1400 may be different; for example, the thermal conductivity of the first thermal control element 1311 may be lower than that of the first adhesive element 1400.

[0111] Figure 1C This is a schematic diagram of an optical module 1002 according to some embodiments of this disclosure, and Figure 1D yes Figure 1C A schematic diagram of some components is shown. In some embodiments, the various components of optical module 1002 are generally similar to those of optical module 1001, with the main difference being that the first thermal control element 1312 of optical module 1002 may be a gap located between base 1112 and optical element 1230 to avoid heat conduction. In this embodiment, base 1112 and carrier 1220 can be connected by a third adhesive element 1313, which may be, for example, glue or welding material, and the thermal conductivity of the third adhesive element 1313 may be different from that of the first adhesive element 1400. This method also prevents heat generated by the first drive assembly 1150 (heat source) from being conducted to optical element 1230.

[0112] Figure 3A This is a schematic diagram of some components of the light intensity adjustment mechanism 1100. Figure 3B This is a top view of some components of the light intensity adjustment mechanism 1100, with the top plate 1113 mainly omitted. Figure 3C This is a top view of some components of the light intensity adjustment mechanism 1100, with other components on the outer frame 1111 mainly omitted. Figure 3D This is a top view of some components of the light intensity adjustment mechanism 1100, where the outer frame 1111 and other components on the outer frame 1111 are mainly omitted.

[0113] like Figures 3A to 3D As shown, an opening can be formed among the first light quantity control unit 1141, the second light quantity control unit 1142, the third light quantity control unit 1143, and the fourth light quantity control unit 1144 of the light quantity control element 1140, with a maximum size of D1, to allow light to pass through. Furthermore, the first light quantity control unit 1141, the second light quantity control unit 1142, the third light quantity control unit 1143, and the fourth light quantity control unit 1144 can be movably connected to the movable part 1120.

[0114] Specifically, in some embodiments, when viewed along the main axis 1500, the first light intensity control unit 1141 includes a first guide groove 1181 extending along a first direction (Y direction), the second light intensity control unit 1142 includes a second guide groove 1182 extending along the first direction, the third light intensity control unit 1143 includes a third guide groove 1183 extending along a second direction (X direction), and the fourth light intensity control unit 1144 includes a fourth guide groove 1184 extending along the second direction.
