Description

Technical Field

[0001] This utility model relates to the field of mobile phone technology, specifically to a lens assembly, a camera module, and an electronic device. Background Technology

[0002] With the continuous development of technology, the waterproof and dustproof performance of electronic devices such as smartphones is receiving increasing attention from consumers. In related technologies, camera lenses in electronic devices have vents that connect to the inside of the device via a waterproof and breathable membrane. This allows for pressure balance between the inside and outside of the device while maintaining a certain level of waterproof and dustproof protection. However, when an electronic device is accidentally submerged in water, the water flow will directly impact the waterproof and breathable membrane through the vents. This impact may damage or cause the membrane to fail, significantly reducing the device's waterproof and dustproof performance. Utility Model Content

Detailed Implementation

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 6 As shown, the lens assembly 100 of this embodiment includes a lens 1, a decorative element 2, and a waterproof and breathable membrane 3 stacked sequentially. The lens 1 has a vent 101, and the decorative element 2 has a vent channel 201, at least a portion of which extends in a tortuous manner. The vent channel 201 communicates with the vent 101. The waterproof and breathable membrane 3 has a first side facing the decorative element 2 and a second side facing away from the decorative element 2. The vent channel 201 is located on the first side of the waterproof and breathable membrane 3 and is in gas communication with the second side of the waterproof and breathable membrane 3 through the membrane.

[0035] In use, the lens assembly 100 of this embodiment allows the vent 101 on the lens 1 to communicate with the outside atmosphere. The vent 101 exchanges gas with the second side (inside the electronic device) of the waterproof and breathable membrane 3 through the vent channel 201, maintaining pressure balance inside and outside the electronic device and preventing damage due to pressure differences. Because the vent channel 201 is tortuous, the impact of water flow is reduced when the electronic device is accidentally submerged in water, thus reducing direct impact on the waterproof and breathable membrane 3 and lowering the risk of damage. Simultaneously, the tortuous vent channel 201 prevents external dust and sharp objects from directly contacting the surface of the waterproof and breathable membrane 3, further reducing the risk of damage and improving its service life and operational reliability. In some embodiments, the ventilation channel 201 includes a first branch channel 2011 and a second branch channel 2012, wherein the length of the first branch channel 2011 is greater than the length of the second branch channel 2012.

[0036] like Figure 4 and Figure 5 As shown, due to the increased length of the first branch channel 2011, the water flow encounters greater resistance when passing through this channel, thus reducing the water flow velocity and impact force, thereby enhancing the waterproof effect. The presence of the first branch channel 2011 and the second branch channel 2012 allows for gas flow along different paths, facilitating faster pressure balance, especially under conditions of drastic pressure changes, and providing greater flexibility for different usage environments. For example, a longer branch channel can be used in applications requiring a higher level of waterproofing, while a shorter branch channel can be used in scenarios with less stringent waterproofing requirements.

[0037] In some embodiments, the first branch channel 2011 is generally C-shaped, and the second branch channel 2012 is generally straight.

[0038] like Figure 4 and Figure 5 As shown, the first branch channel 2011 is generally C-shaped, and the second branch channel 2012 is generally straight. When water flows through the first branch channel 2011 and the second branch channel 2012, the water flow in the generally C-shaped first branch channel 2011 encounters and collides with the water flow in the generally straight second branch channel 2012, thereby absorbing energy and reducing the impact of the water flow on the waterproof and breathable membrane 3, thus protecting the breathable membrane from damage. This structural design can improve the waterproof performance of the waterproof and breathable membrane 3, effectively preventing water from entering even under strong water flow impact, and can improve the waterproof performance to IP68.

[0039] In some embodiments, there are multiple venting channels 201 arranged at intervals. Multiple spaced venting channels 201 can more evenly distribute air pressure, reducing the risk of equipment damage due to uneven air pressure. As the number of channels increases, the overall venting area also increases, which helps to more quickly balance the air pressure inside and outside the equipment, especially in environments with large air pressure fluctuations. When the equipment is submerged in water, the multiple venting channels 201 can disperse the impact force of the water flow, reducing the pressure on individual channels, thereby reducing damage to the waterproof and breathable membrane 3 from the water flow.

[0040] In some embodiments, the ventilation channel 201 includes a first ventilation channel 2013 and a second ventilation channel 2014, wherein the first ventilation channel 2013 and the second ventilation channel 2014 are arranged symmetrically to each other. Figure 4 and Figure 5 As shown, the symmetrically arranged venting channels 201 help to create a more uniform air pressure distribution inside the equipment, reducing stress caused by air pressure differences and protecting the internal structure of the equipment. Because the channels are symmetrical, the impact force of water flow on both sides of the equipment can cancel each other out, reducing the pressure on individual venting channels 201 and improving overall waterproof performance. If one venting channel 201 is blocked or damaged, the other channel can still function; this redundant design disperses the risk of failure and improves the reliability of the equipment.

[0041] In some embodiments, the decorative element 2 is provided with a through hole 203, and the vent hole 101 faces the vent channel 201 to communicate with the vent channel 201. The vent channel 201 communicates with the second side of the waterproof and breathable membrane 3 through the through hole 203. Figures 1 to 6 As shown, the ventilation channel 201 is connected to the second side of the waterproof and breathable membrane 3 through the through hole 203, which further increases the flow path of water and can further protect the waterproof and breathable membrane 3 from direct water flow impact and extend its service life.

[0042] In some embodiments, the decorative member 2 has a first groove 204 on its first surface facing the lens 1, and a boss 205 is provided in the first groove 204 to form a ventilation channel 201 within the first groove 204. (See 2 to...) Figure 5 As shown, the decorative element 2 has a first groove 204 on its first surface facing the lens 1. This groove is likely designed to accommodate a boss 205 and form a ventilation channel 201. The boss 205 is located within the first groove 204, and this boss 205 is likely designed to guide airflow. The presence of the boss 205 creates a ventilation channel 201 within the first groove 204. By using a boss 205 within the first groove 204 to construct the ventilation channel 201, the processing of the ventilation channel 201 is simplified, making it easier to manufacture.

[0043] In some embodiments, the boss 205 includes a central boss 205, a first side boss 2052, and a second side boss 2053. The first side boss 2052 is located on the first side of the central boss 205, and the second side boss 2053 is located on the second side of the central boss 205. The ventilation channel 201 includes a first ventilation channel 2013 located on the first side of the central boss 205, a second ventilation channel 2014 located on the second side of the central boss 205, and a connecting channel 2015. The first end of the first ventilation channel 2013 communicates with the first end of the second ventilation channel 2014, and the second end of the first ventilation channel 2013 communicates with the second end of the second ventilation channel 2014 through the connecting channel 2015. The arrangement of multiple bosses 205 can effectively collide with the water flow, consume the kinetic energy of the water flow as much as possible, reduce the impact of the water flow on the waterproof and breathable membrane 3, thereby improving the working reliability and service life of the waterproof and breathable membrane 3, and thus improving the waterproof and dustproof performance of electronic devices.

[0044] In some embodiments, the vent 101 faces the connection channel 2015 to communicate with the connection channel 2015. For example... Figure 5 As shown, the vent 101 directly faces the connecting channel 2015, making the connection between the vent 101 and the connecting channel 2015 simple and convenient, without the need for additional connecting parts, which helps to improve the assembly efficiency of the lens assembly 100.

[0045] In some embodiments, the decorative member 2 has a through hole 203 extending along its thickness direction, and the first end of the first ventilation channel 2013 and the first end of the second ventilation channel 2014 are respectively connected to the through hole 203. Figure 5 As shown, the first ventilation channel 2013 and the second ventilation channel 2014 share a through hole 203 to communicate with the gas on the second side of the waterproof and breathable membrane 3, which makes the structure of the decorative part 2 simple and easy to process and manufacture.

[0046] In some embodiments, the central boss 205 is generally trapezoidal, with a first side boss 2052 and a second side boss 2053 symmetrically arranged on both sides of the central boss 205. The generally trapezoidal shape of the central boss 205 helps guide airflow, reduces water flow impact, and increases the structural strength of the decorative element 2. The symmetrical arrangement of the first side boss 2052 and the second side boss 2053 on both sides of the central boss 205 helps maintain a uniform distribution of air pressure and reduces stress concentration.

[0047] In some embodiments, the outer peripheral surface of each of the first side boss 2052 and the second side boss 2053 includes a plane facing the intermediate boss 205 and a curved surface facing away from the intermediate boss 205.

[0048] like Figure 5 As shown, the outer peripheral surfaces of the first side boss 2052 and the second side boss 2053 include a flat surface facing the intermediate boss 205 and a curved surface facing away from the intermediate boss 205. This arrangement helps guide airflow while reducing the impact of water flow on the ventilation channel 201. The flat portion is used to form a stable contact with the intermediate boss 205, while the curved portion may help the airflow transition smoothly and reduce airflow resistance in the channel.

[0049] In some embodiments, the outer periphery of the first groove 204 includes a straight segment 2041, a first oblique segment 2042, a second oblique segment 2043, a first arcuate segment 2044, and a second arcuate segment 2045 opposite to the long bottom edge of the intermediate boss 205. The first end of the first oblique segment 2042 is connected to the first end of the straight segment 2041, the first end of the second oblique segment 2043 is connected to the second end of the straight segment 2041, the second end of the first oblique segment 2042 is connected to the first end of the first arcuate segment 2044, and the second end of the second oblique segment 2043 is connected to the first end of the second arcuate segment 2045. The second ends of the first oblique segment 2042 and the second ends of the second oblique segment 2043 extend obliquely away from each other. The second end of the first arc segment 2044 is spaced apart from the second end of the second arc segment 2045 to form a connecting port 206. The short top edge of the intermediate boss 205 is located inside the connecting port 206 to divide the connecting port 206 into a first sub-connecting port 2061 and a second sub-connecting port 2062.

[0050] like Figure 5As shown, the outer periphery of the first groove 204 includes a straight segment 2041, an oblique segment, and an arc segment. These different line segments and arc segments may help guide airflow and reduce airflow resistance in the channel. The second end of the first arc segment 2044 is spaced apart from the second end of the second arc segment 2045 to form a connecting opening 206, which helps optimize the airflow path while reducing the impact of water flow on the ventilation channel 201. The short top edge of the intermediate boss 205 is located within the connecting opening 206 to divide the connecting opening 206 into a first sub-connecting opening 2061 and a second sub-connecting opening 2062, which helps to further optimize the airflow path while reducing the impact of water flow on the ventilation channel 201, reducing airflow resistance in the channel, and improving ventilation efficiency.

[0051] In some embodiments, the decorative member 2 is provided with a through hole 203 extending along its thickness direction, a first ventilation channel 2013 communicating with the through hole 203 through a first sub-connection port 2061, and a second ventilation channel 2014 communicating with the through hole 203 through a second sub-connection port 2062.

[0052] In some embodiments, the decorative member 2 has a second groove 207 on its second surface facing the waterproof and breathable membrane 3. The second groove 207 communicates with the breathable channel 201, and the waterproof and breathable membrane 3 covers the opening of the second groove 207.

[0053] like Figure 5 As shown, when the ventilation channel 201 vents air or water into the electronic device, the gas or water in the ventilation channel 201 first enters the second groove 207 for diffusion and pressure reduction, reducing its impact on the waterproof and breathable membrane 3, and further improving the service life of the waterproof and breathable membrane 3.

[0054] In some embodiments, the lens assembly 100 includes a first adhesive layer 4, the lens 1 is connected to the decorative element 2 through the first adhesive layer 4, the first adhesive layer 4 has a first clearance hole 401, and the vent hole 101 communicates with the vent channel 201 through the first clearance hole 401.

[0055] Such as 2 and Figure 3 As shown, the lens 1 is connected to the decorative element 2 via the first adhesive layer 4, ensuring a secure connection between the lens 1 and the decorative element 2. The first adhesive layer 4 has a first clearance hole 401, which allows the vent hole 101 to pass through, thereby enabling the ventilation channel 201 to connect. The vent hole 101 connects to the ventilation channel 201 via the first clearance hole 401, ensuring that gas can flow smoothly from the inside of the device to the outside.

[0056] In some embodiments, the lens assembly 100 further includes a second adhesive layer 5, the waterproof and breathable membrane 3 is connected to the decorative element 2 through the second adhesive layer 5, the second adhesive layer 5 has a second clearance hole 501, and the waterproof and breathable membrane 3 is connected to the breathable channel 201 through the second clearance hole 501.

[0057] Such as 2 and Figure 3 As shown, the waterproof and breathable membrane 3 is mounted on the decorative component 2, allowing it to be spaced apart from the chip inside the electronic device. This prevents water from directly affecting the screen chip and causing a black screen. The waterproof and breathable membrane 3 is connected to the decorative component 2 via the second adhesive layer 5, ensuring a secure connection. The second adhesive layer 5 has a second clearance hole 501, which allows the waterproof and breathable membrane 3 to pass through, thus connecting the ventilation channel 201. The connection between the waterproof and breathable membrane 3 and the ventilation channel 201 via the second clearance hole 501 ensures that gas can flow smoothly from the inside of the device to the outside.

[0058] In some embodiments, the lens assembly 100 further includes a support plate 6, which is disposed on the second side of the waterproof and breathable membrane 3 away from the decorative element 2. The waterproof and breathable membrane 3 is sandwiched between the support plate 6 and the decorative element 2. The support plate 6 has a third clearance hole 601 that communicates with the air venting channel 201 through the waterproof and breathable membrane 3.

[0059] Such as 2 and Figure 3 As shown, the waterproof and breathable membrane 3 is sandwiched between the support plate 6 and the decorative element 2. This arrangement helps protect the waterproof and breathable membrane 3 and ensures the effectiveness of its function. The support plate 6 has a third clearance hole 601, which allows airflow to communicate with the breathable channel 201 through the waterproof and breathable membrane 3, thereby achieving air pressure balance.

[0060] In some embodiments, the lens assembly 100 further includes a third adhesive layer 7, which is disposed on the side of the support plate 6 away from the waterproof and breathable membrane 3, and the third adhesive layer 7 has a fourth clearance hole 701 communicating with the third clearance hole 601.

[0061] Such as 2 and Figure 3 As shown, the lens assembly 100 also includes a third adhesive layer 7, which is disposed on the side of the support plate 6 opposite to the waterproof and breathable membrane 3, and helps to support and fix the support plate 6. The third adhesive layer 7 has a fourth clearance hole 701 communicating with the third clearance hole 601. The presence of this hole allows airflow through the support plate 6, thereby achieving air pressure balance.
