[0003] Optical modules usually include optical components (such as cameras, flashlights, infrared transmitters, etc.) and lenses between the optical components and the external environment. In order to achieve dust-proof effects, the humidity of the optical module assembly production line is relatively high, resulting in high humidity inside the optical module cavity. Optical components will generate heat when working for a long time, and the temperature of the external environment is relatively low, resulting in a large temperature difference between the inside and outside of the lens. The water vapor evaporated by heat inside the optical module cavity is easily condensed when it encounters cold, forming a layer of water mist on the inside of the lens.
[0004] The mist formed on the inside of the lens affects the use of optical elements. Utility Model Content

[0038] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0039] 1. Lens assembly 10
[0040] Reference Figure 1 As shown, Figure 1 1 is a schematic diagram of the structure of a lens assembly 10 provided in an embodiment of the present disclosure. The embodiment of the present disclosure provides a lens assembly 10. The lens assembly 10 may include a lens body 1 and a one-way ventilation assembly 2.
[0041] The various components of the lens assembly 10 are introduced below:
[0042] 1.1 Lens body 1
[0043] The lens body 1 may have a first through hole 1 a , and water vapor and high-temperature gas inside the lens body 1 may be discharged to the outside of the lens body 1 through the first through hole 1 a .
[0044] The present disclosure does not specifically limit the number of the first through holes 1a, and can be set according to factors such as the amount of gas discharged from the inner side of the lens body 1 and the volume of the receiving groove 31 of the support member 3 in the optical module 100. One first through hole 1a can be opposite to multiple one-way ventilation components 2, and multiple first through holes 1a can also be opposite to one one-way ventilation component 2.
[0045] The present disclosure does not specifically limit the shape and cross-sectional area of the first through hole 1a, and can be matched and set according to factors such as the aesthetics of the electronic device and the processing cost of the first through hole 1a.
[0046] The lens body 1 may have a light-transmitting area through which light may pass. The light-transmitting area is opposite to the optical element 4 in the optical module 100. For example, when the optical element 4 is a camera, light in the external environment may pass through the light-transmitting area and enter the interior of the camera. For another example, when the optical element 4 is a flash, light emitted by the flash may pass through the light-transmitting area and shine on the object to be photographed.
[0047] The present disclosure does not specifically limit the material of the lens body 1, and it can be matched and selected according to factors such as the usage scenario of the lens assembly 10 and economic cost. For example, the material of the lens body 1 can be resin, glass, acrylic (plexiglass), etc.
[0048] 1.2 One-way ventilation component 2
[0049] The one-way ventilation component 2 is located at the first through hole 1a of the lens body 1 and is connected to the lens body 1. The water vapor and high-temperature gas inside the lens body 1 can first pass through the one-way ventilation component 2 and then be discharged to the outside of the lens body 1, i.e., the external environment of the electronic device, through the first through hole 1a, so as to reduce the temperature difference between the gas inside and outside the lens body 1.
[0050] The ventilation direction of the one-way ventilation component 2 is the direction in which the one-way ventilation component 2 points to the first through hole 1a. The ventilation direction of the one-way ventilation component 2 is unidirectional, which ensures that the water vapor and high-temperature gas inside the lens body 1 can be discharged to the outside of the lens body 1 through the one-way ventilation component 2 and the first through hole 1a, while preventing foreign matter in the external environment from entering the inside of the lens body 1, that is, the receiving groove 31 area of the optical module 100, through the first through hole 1a and the one-way ventilation component 2, thereby causing damage or scrapping to the optical element 4 in the receiving groove 31 area.
[0051] Reference Figure 2 As shown, Figure 2 It is a partial schematic diagram of a lens assembly 10 provided in an embodiment of the present disclosure. The one-way ventilation assembly 2 may include a shell 21 and a movable part 22.
[0052] 1.2.1 Shell 21
[0053] The housing 21 has a cavity, and has a first end wall 211 and a second end wall 212 opposite to each other.
[0054] The present disclosure does not make any specific restrictions on the material of the shell 21, and can be matched and set according to factors such as the use scenario of the shell 21 and the processing cost. Unless otherwise specified, the present disclosure uses the shell 21 as polyester resin (PET) as an example for explanation, and other similar situations will not be repeated.
[0055] The present disclosure does not specifically limit the processing technology of the shell 21. For example, the first end wall 211 and the second end wall 212 can be formed by an integrated process such as injection molding or casting. For another example, when the first end wall 211 and the second end wall 212 are both made of polyester resin, they can be processed separately and plasma treated to increase the viscosity of the surfaces of the first end wall 211 and the second end wall 212, and then strong adhesive silicone is coated on the contact surface of the first end wall 211 and the second end wall 212 to stably bond the first end wall 211 and the second end wall 212 together.
[0056] The first end wall 211 has a second through hole 211a, and the second end wall 212 has a third through hole 212a. The water vapor and high-temperature gas inside the lens body 1 can enter the cavity of the housing 21 through the third through hole 212a. The first end wall 211 is connected to the lens body 1. The water vapor and high-temperature gas entering the cavity of the housing 21 can enter the first through hole 1a of the lens body 1 through the second through hole 211a, and then be discharged to the outside of the lens body 1.
[0057] The present disclosure does not specifically limit the number of the second through holes 211a, which can be set according to factors such as the area of the first end wall 211 and the area of the first through hole 1a of the lens body 1. Multiple second through holes 211a can be opposite to the same first through hole 1a, or multiple second through holes 211a can be opposite to multiple first through holes 1a one by one.
[0058] The present disclosure does not specifically limit the number of the third through holes 212a, which can be set according to factors such as the area of the second end wall 212. The plurality of third through holes 212a can be evenly distributed on the second end wall 212, or concentrated in the area where the water vapor and high-temperature gas are generated on the second end wall 212 facing the inner side of the lens body 1.
[0059] 1.2.2 Moving parts 22
[0060] The movable member 22 is located in the cavity of the housing 21. The movable member 22 has a fourth through hole 22a. The fourth through hole 22a is opposite to the second through hole 211a and staggered with the third through hole 212a. There is attraction between the movable member 22 and the second end wall 212. The water vapor and high-temperature gas inside the lens body 1 can enter the cavity of the housing 21 through the third through hole 212a, and then enter the first through hole 1a of the lens body 1 through the fourth through hole 22a and the second through hole 211a in sequence, and then be discharged to the outside of the lens body 1.
[0061] The present disclosure does not specifically limit the number of the fourth through holes 22 a , and the number of the fourth through holes 22 a may be matched and set according to factors such as the number of the second through holes 211 a and the number of the third through holes 212 a .
[0062] In some embodiments, the movable member 22 and the second end wall 212 have opposite magnetic properties on the sides close to each other, and the attraction is magnetic attraction. Figure 2 As shown, the first surface of the second end wall 212 and the second surface of the movable part 22 have opposite magnetic properties. At this time, there is a magnetic attraction between the first surface and the second surface. When there is no expanding gas exerting a push force on the movable part 22 in the opposite direction to the magnetic attraction or the push force is smaller than the magnetic attraction, under the action of the magnetic attraction, the first surface of the second end wall 212 and the second surface of the movable part 22 fit each other.
[0063] The present disclosure does not specifically limit the value of the magnetic attraction force, and it can be set according to the magnitude of the pushing force applied by the expansion gas to the movable part 22 .
[0064] The present disclosure does not specifically limit the magnetism generating principle of the first surface of the second end wall 212 and the second surface of the movable part 22. For example, the first surface of the second end wall 212 and the second surface of the movable part 22 may be coated with magnetic material. For another example, when the second end wall 212 and the movable part 22 are made of specific metal materials (for example, iron, nickel, and cobalt, etc.), the first surface of the second end wall 212 and the second surface of the movable part 22 may be subjected to certain magnetization treatment.
[0065] The first end wall 211 does not have magnetism, and there is no magnetic attraction force between the movable member 22 and the first end wall 211 on a side close to each other.
[0066] In some embodiments, reference Figure 2 As shown, the first surface of the second end wall 212 close to the movable member 22 has a first electrostatic layer 212b, and the second surface of the movable member 22 close to the second end wall 212 has a second electrostatic layer 22b, and there is an electrostatic attraction force between the first electrostatic layer 212b and the second electrostatic layer 22b.
[0067] When there is no expanding gas exerting a push force on the movable part 22 in the opposite direction to the electrostatic attraction or the push force is smaller than the electrostatic attraction, the first surface of the second end wall 212 and the second surface of the movable part 22 fit together under the action of the electrostatic attraction.
[0068] The present disclosure does not specifically limit the value of the electrostatic attraction force, and it can be set according to the magnitude of the pushing force applied by the expansion gas to the movable part 22 .
[0069] The first electrostatic layer 212b has a fifth through hole corresponding to the third through hole 212a, so as to ensure that water vapor and high-temperature gas in the inner side of the lens body 1 and the receiving groove 31 of the support member 3 can pass through the second end wall 212 and the first electrostatic layer 212b. Based on the same principle, the second electrostatic layer 22b has a sixth through hole corresponding to the third through hole 212a, so as to ensure that water vapor and high-temperature gas in the inner side of the lens body 1 and the receiving groove 31 of the support member 3 can pass through the movable member 22 and the second electrostatic layer 22b.
[0070] In some embodiments, the shape of the first surface of the second end wall 212 close to the movable member 22 matches the shape of the second surface of the movable member 22 close to the second end wall 212. Under the effect of the attraction force, the first surface and the second surface with matching surface shapes fit more closely, which can improve the sealing performance of the one-way ventilation component 2 and further prevent foreign matter in the external environment from entering the inner side of the lens body 1 through the one-way ventilation component 2.
[0071] The first surface is a plane, and the second surface is a plane. The first surface and the second surface are both planes, which can simplify the processing technology of the second end wall 212 and the movable member 22, and also facilitate the installation of the housing 21 and the movable member 22.
[0072] 1.2.3 Working process of one-way ventilation component 2
[0073] The movable part 22 can move in the cavity of the shell 21. When the user does not use the optical module 100, the optical element 4 is in a non-working state, the optical element 4 does not generate heat, and the gas in the inner side of the lens body 1 and the area of the receiving groove 31 of the support member 3 is at room temperature and does not expand. At this time, due to the attraction between the movable part 22 and the second end wall 212, the movable part 22 and the second end wall 212 are attached together, and the fourth through hole 22a of the movable part 22 and the third through hole 212a of the second end wall 212 are mutually misaligned. Therefore, the gas in the inner side of the lens body 1 and the area of the receiving groove 31 of the support member 3 is isolated from the external environment, and the external gas cannot pass through the shell 21 and the movable part 22 to enter the inner side of the lens body 1 and the area of the receiving groove 31 of the support member 3.
[0074] When the user uses the optical module 100, the optical element 4 is in working state, the optical element 4 generates heat, and the gas in the inner side of the lens body 1 and the area of the receiving groove 31 of the support member 3 expands due to the heat. When the top force of the expanding gas received by the movable member 22 is greater than the attraction between the movable member 22 and the second end wall 212, the movable member 22 separates from the second end wall 212, moves to the first end wall 211 and fits with the first end wall 211, and the fourth through hole 22a of the movable member 22 is opposite to the second through hole 211a of the first end wall 211, so the gas in the inner side of the lens body 1 and the area of the receiving groove 31 of the support member 3 is connected with the external environment, and the water vapor and high-temperature gas in the inner side of the lens body 1 and the area of the receiving groove 31 of the support member 3 are discharged to the outside of the lens body 1 through the third through hole 212a, the fourth through hole 22a, the second through hole 211a of the one-way ventilation component 2 and the first through hole 1a of the lens body 1.
[0075] 1.2.4 Ventilation and dustproof parts 23
[0076] The one-way ventilation assembly 2 may further include a breathable dustproof member 23, which is located between the first end wall 211 and the lens body 1, and is respectively connected to the first end wall 211 and the lens body 1. The breathable dustproof member 23 can block the passage of liquid and solid foreign matter while ensuring the passage of gas, so as to ensure that foreign matter in the external environment is effectively intercepted when entering the breathable dustproof member 23 through the first through hole 1a of the lens body 1, so as to prevent it from entering the inner side of the lens body 1, i.e., the receiving groove 31 area of the optical module 100, through the cavity of the housing 21, thereby causing damage or scrapping to the optical element 4 in the receiving groove 31 area.
[0077] 2. Optical module 100
[0078] Based on the same concept, the embodiment of the present disclosure further provides an optical module 100 , which may include a lens assembly 10 as described in any one of the above embodiments.
[0079] Reference Figure 3 As shown, Figure 3 is a partial schematic diagram of an optical module 100 provided in an embodiment of the present disclosure. The optical module 100 may further include a support member 3 and an optical element 4.
[0080] 2.1 Support 3
[0081] The support member 3 has a receiving groove 31, the notch of which is connected to the lens body 1, and the one-way ventilation assembly 2 is located on one side of the lens body 1 close to the receiving groove 31. The receiving groove 31 can be used to receive the optical element 4 or other elements required by the electronic device.
[0082] The present disclosure does not specifically limit the volume and shape of the receiving groove 31 , and can be matched and set according to factors such as the volume, shape, and line direction of the optical element 4 or other electronic element to be received.
[0083] At least a portion of the receiving groove 31 is opposite to the light-transmitting area of the lens body 1 , so that the optical element 4 can work normally to emit or receive light.
[0084] 2.2 Optical elements 4
[0085] The optical element 4 is located in the receiving groove 31 and is connected to the support member 3. The optical element 4 is located in the area where the receiving groove 31 is opposite to the light-transmitting area of the lens body 1. For example, when the optical element 4 is a camera, light in the external environment can pass through the light-transmitting area to enter the camera. For another example, when the optical element 4 is a flash, the light emitted by the flash can pass through the light-transmitting area to illuminate the object to be photographed.
[0086] The present disclosure does not specifically limit the number of optical elements 4, and can be matched and set according to the requirements of different electronic devices for the optical module 100. The present disclosure does not specifically limit the type of optical element 4, and can be matched and set according to the required functions of the optical module 100. For example, the optical element 4 can be one or more of a flash, a camera, an infrared transmitter, and an ultraviolet receiver.
[0087] 2.3 Drying sheet 5
[0088] The optical module 100 may further include a drying sheet 5, referring to Figure 4 As shown, Figure 4It is a structural schematic diagram of an optical module provided by an embodiment of the present disclosure, in which a drying sheet 5 is located in a receiving groove 31 and is connected to a support member 3. The drying sheet 5 is a drying sheet 5 made of a moisture-controlling fiber material, which senses changes in ambient humidity and uses its own physical structure and chemical properties to achieve regulation of ambient humidity. In addition, the drying sheet 5 made of a moisture-controlling fiber material is reversible, can absorb and release moisture repeatedly, and has a very long service life. When the humidity in the receiving groove 31 area is high, moisture can be quickly absorbed to reduce the humidity of the surrounding environment and prevent the generation of water mist on the inner side of the lens body 1; when the humidity in the receiving groove 31 area is low, the absorbed moisture can be released, and the humidity of the space can be kept stable for a long time.
[0089] The present disclosure does not specifically limit the shape of the drying sheet 5, and it can be set according to the placement space of the drying sheet 5. For example, the drying sheet 5 can be annular, and its center coincides with the geometric center of the optical element 4, so as to regulate the humidity of the local environment around the optical element 4. The drying sheet 5 can be rectangular and evenly distributed in the area surrounded by the receiving groove 31, so as to regulate the humidity in the area.
[0090] The preferred placement position of the drying sheet 5 is the area inside the receiving groove 31 close to the inner side of the lens body 1. At this time, the drying sheet 5 regulates the humidity of the local environment around the inner side of the lens body 1 to avoid excessive humidity in the local environment around the inner side of the lens body 1. After the moisture in the local environment contacts the inner side of the lens body 1, it condenses when it encounters cold, forming a layer of water mist attached to the inner wall of the lens body 1.
