Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to an aperture device, camera module and electronic device. Background Technology

[0002] Mobile phones, tablets, and other electronic devices are typically equipped with camera modules to enable them to record video. Adjusting the intensity and angle of light entering the camera module is a key technology for improving image quality, and this intensity and angle can be controlled by the aperture. The aperture is a device used to control the amount of light passing through the lens of the camera module and entering the photosensitive surface inside the camera body; it is usually located inside the lens.

[0003] In existing technology, the aperture includes multiple light-shielding parts, which are circumferentially spaced and can form an aperture hole. Each light-shielding part is connected to a drive motor. The drive motor controls the position of the light-shielding parts, thereby adjusting the size of the aperture hole formed by the multiple light-shielding parts, and controlling the amount of light entering the photosensitive surface inside the camera body. To ensure the light-shielding effect, multiple light-shielding parts are provided, and the displacement direction of each light-shielding part is different, which means that the drive motors cannot be shared, thus requiring multiple drive motors. Having more drive motors increases the cost of the camera module; furthermore, each drive motor needs to be electrically connected to a power source, resulting in higher power consumption of the camera module and affecting the battery life of the electronic device.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0043] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or it can be located in between the component.

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] This embodiment provides an electronic device with a long battery life. Exemplarily, the electronic device can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR headset, virtual reality (VR) glasses, or VR headset, or any other device with a camera module.

[0046] The camera module of an electronic device can be located inside the device. The camera module is used to capture ambient light from outside the device. The camera module can be electrically connected to the main circuit board of the electronic device. This allows for signal transmission between the camera module and the main circuit board. It is understood that the camera module can be a rear-facing camera module or a front-facing camera module, etc.

[0047] In some implementations, the camera module can be located inside the electronic device. The camera module can be fixed to the side of the electronic device's screen facing the back cover. The back cover can have a through-hole. The shape of the through-hole is not limited to circular. The through-hole can be used to connect the interior of the electronic device to the exterior. Light from outside the electronic device can enter the interior through the through-hole in the back cover. The camera module can capture ambient light entering the interior of the electronic device.

[0048] For example, the camera module may include an aperture device and a lens assembly. The optical axis of the camera module may include the optical axis of the aperture device and the optical axis of the lens assembly. The lens assembly may be a fixed-focus lens, an autofocus (AF) lens, or a zoom lens, etc., and this embodiment is not limited thereto.

[0049] The lens assembly may include a lens and a motor. The lens may be mounted on the motor. The motor may be used to drive the lens to move along the optical axis of the camera module. The motor may be a voice coil motor or a shape memory alloy (SMA) motor. This application does not limit the specific structure of the motor.

[0050] The aperture device can be positioned opposite the through-hole on the rear cover. The lens can be positioned opposite the aperture opening of the aperture device. In this way, light from the scene can enter the lens through the aperture opening. The aperture device can adjust the amount of light entering the lens by adjusting the size of the aperture opening positioned opposite the lens.

[0051] For example, when the electronic device is shooting in low light conditions, the aperture device can be adjusted to a larger aperture opening relative to the lens, increasing the amount of light entering the lens assembly. When the electronic device is shooting in bright light conditions, the aperture device can be adjusted to a smaller aperture opening relative to the lens, reducing the amount of light entering the lens assembly.

[0052] Next, this embodiment will provide a detailed description of the specific structure of the aperture device.

[0053] The aperture device provided in this embodiment can have a lower cost and lower power consumption, thus reducing the impact on the battery life of electronic devices.

[0054] For example, such as Figures 1 to 8As shown, the aperture device includes a housing 100, a support member 200, an aperture structure 300, and a drive member 400. The housing 100 has a receiving groove 110 and a through hole 120 communicating with the receiving groove 110. In some optional embodiments, the housing 100 has a first surface (not shown) and a second surface (not shown) disposed opposite to each other in its axial direction. The receiving groove 110 is formed on the first surface, and the through hole 120 is formed on the second surface, communicating with the receiving groove 110. The receiving groove 110 is used to receive the support member 200, the aperture structure 300, etc., and the through hole 120 is disposed opposite to and communicates with a light-transmitting hole on an electronic device.

[0055] In this embodiment, the support member 200 is movably disposed within the receiving groove 110 for protection. The aperture structure 300 is disposed within the receiving groove 110 for positioning. The portion of the aperture structure 300 is located on the side of the support member 200 facing the shell through hole 120, such that the aperture structure 300 has a portion located between the shell through hole 120 and the support member 200. The aperture structure 300 has multiple aperture holes 310 with not identical diameters; that is, the aperture structure 300 has multiple aperture holes 310 with not identical diameters. Any two aperture holes 310 can have the same or different diameters. Thus, the aperture structure 300 can have aperture holes 310 with larger diameters as well as aperture holes 310 with smaller diameters. The through-hole 120 can be collinear with the axis of any aperture hole 310, meaning that any aperture hole 310 can be opposite to the through-hole 120, allowing light passing through the through-hole 120 to also pass through the aperture hole 310. It should be noted that the aperture structure 300 is movably disposed within the receiving groove 110, allowing the aperture structure 300 to move relative to the housing 100. When the aperture structure 300 moves, it can adjust the alignment of the aperture hole 310 with the axis of the through-hole 120.

[0056] Optionally, in this embodiment, the movement of the aperture structure 300 relative to the housing 100 can be achieved by a driving member 400. The driving end 410 of the driving member 400 is connected to the aperture structure 300 and configured to drive the aperture structure 300 to move relative to the housing 100, thereby adjusting the aperture hole 310 which is collinear with the axis of the housing through hole 120. By setting the driving member 400, on the one hand, the accuracy of driving the movement of the aperture structure 300 can be improved, achieving precise rotation of the aperture structure 300 and thus enabling rapid switching of the aperture structure 300's position; on the other hand, it makes the aperture device more intelligent.

[0057] Optionally, the driving component 400 in this embodiment can be a motor, electric motor, or other driving part; this embodiment is not limited in this regard. When the driving component 400 is a motor, it can be a voice coil motor, stepper motor, linear motor, or shape memory alloy (SMA) motor; this embodiment is not limited in this regard. Optionally, a reducer can be combined with the motor to provide stable power output.

[0058] In some alternative embodiments, the drive element 400 can be disposed on the support element 200 for fixation, allowing the drive element 400 to be located within the housing 100 without occupying external space, thus facilitating miniaturization of the voice coil device. It is understood that the drive element 400 can also be directly disposed on the housing 100; this embodiment does not limit this to that.

[0059] When using the voice coil device provided in this embodiment, when it is necessary to increase the light throughput into the lens assembly, the driving member 400 is activated, thereby driving the aperture structure 300 to move relative to the housing 100. This causes the aperture hole 310 with a larger diameter of the aperture structure 300 to move closer to the housing through hole 120 until the larger aperture hole 310 is collinear with the axis of the housing through hole 120, thus satisfying the requirement of high light throughput. When it is necessary to reduce the light throughput into the lens assembly, the driving member 400 is activated to drive the aperture structure 300 to move relative to the housing 100. This causes the aperture hole 310 with a smaller diameter of the aperture structure 300 to move closer to the housing through hole 120 until the smaller aperture hole 310 is collinear with the axis of the housing through hole 120, thus satisfying the requirement of low light throughput.

[0060] The aperture device provided in this embodiment has multiple aperture holes 310 with different diameters on the aperture structure 300, so that multiple light flux requirements can be met by setting one aperture structure 300. The number of aperture structures 300 is small, and the movement of the aperture structure 300 relative to the housing 100 can be realized by a driving member 400, which reduces the number of driving members 400. This reduces the number of components in the aperture device, thereby reducing the cost of the aperture device. In addition, the small number of driving members 400 reduces the number of power-consuming components in the aperture device, which also enables the aperture device to have lower power consumption and reduces the impact of the aperture device on the battery life of electronic devices.

[0061] In this embodiment, the housing 100 can be part of the outer casing of an electronic device, that is, it can be an integral structure molded together with the outer casing of the electronic device. Of course, it is understood that the housing 100 can also be an independent structure from the outer casing, with the two fixedly connected. The material of the housing 100 can be a metal (e.g., aluminum alloy) or a non-metallic material (e.g., engineering plastic), and this embodiment does not limit this. In this embodiment, since the lens assembly is typically circular, the housing 100 is also cylindrical. To reduce optical interference, the outer wall of the housing 100 in this embodiment is treated with an anti-reflective coating.

[0062] The support member 200 in this embodiment can be made of metal or non-metal. For example, the support member 200 can be made of plastic.

[0063] In some optional embodiments, the aperture structure 300 in this embodiment can be in the form of a thin sheet. On the one hand, the aperture structure 300 can occupy less space and be lighter in weight. The material of the aperture structure 300 can be metal or non-metal, and this embodiment is not limited in this regard. In order to improve the light-shielding effect of the aperture structure 300, a light-shielding material can also be coated on the aperture structure 300, and this embodiment is not limited in this regard.

[0064] In one embodiment, the aperture structure 300 can be an elastic structure, that is, the aperture structure 300 can undergo elastic deformation, so that the aperture structure 300 can occupy a small space within the housing 100. For example, the aperture structure 300 is formed of a material such as shape memory metal, which is capable of elastic deformation.

[0065] In other embodiments, the aperture structure 300 can be a flexible structure. In this case, the support member 200 and the housing 100 can cooperate to shape the aperture structure 300, so that the aperture structure 300 located near the housing through hole 120 can be relatively flat. For example, the material of the aperture structure 300 can be fiber, etc.

[0066] In other embodiments, the aperture structure 300 can also be a structure with a certain degree of toughness. In this case, the aperture structure 300 will not break when it moves within the housing 100, thus having high reliability.

[0067] In some alternative embodiments, such as Figure 4As shown, a folding space 210 is formed between the support member 200 and the sidewall of the receiving groove 110. That is, the support member 200 is not in direct contact with the groove wall of the receiving groove 110, but there is a gap between them. A portion of the aperture structure 300 is located between the support member 200 and the bottom wall of the receiving groove 110 to form an unfolded portion 320, and another portion is folded into the folding space 210 to form a folded portion 330. The shell through hole 120 and an aperture hole 310 located in the unfolded portion 320 are collinear. Because the unfolded portion 320 is relatively flat, the aperture hole 310 and the shell through hole 120 are arranged opposite each other, avoiding the eccentricity of the aperture hole 310 and the shell through hole 120 caused by the wrinkles of the aperture structure 300.

[0068] It should be noted that by folding a portion of the aperture structure 300 into the folding space 210, the structure of the aperture device is made compact, which allows the overall area of ​​the aperture structure 300 to be large, while requiring less space. This enables the aperture structure 300 to have a large area even in electronic devices with high space requirements, allowing for the opening of multiple aperture holes 310 with different diameters to meet the different light throughput requirements of electronic devices, thus exhibiting high stability and flexibility.

[0069] It should also be noted that any portion of the aperture structure 300 located between the support member 200 and the bottom wall of the receiving groove 110 is referred to as the unfolded portion 320, and any portion folded into the folding space 210 is referred to as the folded portion 330. Since the aperture structure 300 can move relative to the housing 100, the unfolded portion 320 does not specifically refer to a certain area on the aperture structure 300. Similarly, the folded portion 330 does not specifically refer to a certain area on the aperture structure 300. That is, the positions of the unfolded portion 320 and the folded portion 330 relative to the aperture structure 300 are not fixed, but change with the position of the aperture structure 300 relative to the housing 100. In this embodiment, the unfolded portion 320 and the folded portion 330 are defined only for ease of description.

[0070] In one possible implementation, such as Figure 3 As shown, the folded portion 330 is bent relative to the unfolded portion 320, and the folded portion 330 is arranged around the outer periphery of the unfolded portion 320. Thus, the entire aperture structure 300 occupies less space in the direction perpendicular to the axis of the housing 100, which is beneficial for miniaturization of the aperture device. Furthermore, it facilitates the unfolding of the aperture structure 300. The fact that the folded portion 330 is arranged around the outer periphery of the unfolded portion 320 indicates that there are gaps between the support member 200 and the circumferential groove sidewall of the receiving groove 110, thereby allowing for further folding of the aperture structure 300 to reduce the required space.

[0071] Optionally, the angle between the folded portion 330 and the unfolded portion 320 can be greater than 90 degrees, equal to 90 degrees, or less than 90 degrees; this embodiment does not limit this.

[0072] In one possible implementation, such as Figure 4 As shown, the driving element 400 is configured to drive the aperture structure 300 to rotate about a first axis X1 as the rotation center, wherein the first axis X1 is parallel to the axis of the housing 100. With this configuration, the movement of the aperture structure 300 within the housing 100 is rotational, resulting in a smaller range of motion for the driving element 400. This eliminates the need for a large operating space for the driving element 400, thereby reducing the space required for the aperture device. Furthermore, the size of the housing 100 does not need to be large, meeting the requirements of miniaturization.

[0073] In this embodiment, multiple aperture holes 310 are arranged at intervals along the circumference of the aperture structure 300. When the driving member 400 drives the aperture structure 300 to rotate around the first axis X1 as the rotation center, the multiple aperture holes 310 pass through the shell through hole 120 one by one. When the aperture hole 310 of the required aperture diameter passes through the shell through hole 120 and is collinear with the axis of the shell through hole 120, the driving member 400 is controlled to stop driving. At this time, the light flux passing through the aperture hole 310 is the required light flux.

[0074] For example, such as Figure 8 As shown, this embodiment provides an aperture structure 300 in a fully deployed state, that is, the aperture structure 300 is flat. The center of the aperture structure 300 is a connection position 340, which is used to connect to the driving end 410 of the driving member 400. Figure 8 As can be seen, multiple aperture holes 310 surround the outer periphery of the connection position 340 and are spaced apart. Among them, Figure 8 The illustration shows a case where there are four aperture holes 310, and the aperture sizes of the four aperture holes 310 are completely different, but this is not a limitation.

[0075] Optionally, such as Figure 6As shown, the support member 200 has a support surface 220 and a guide surface 230. The support surface 220 is positioned towards the bottom wall of the receiving groove 110. The guide surface 230 is inclined relative to the support surface 220, and the distance between the support surface 220 and the bottom wall of the receiving groove 110 is greater than the distance between the guide surface 230 and the bottom wall of the receiving groove 110. That is, the guide surface 230 is lower than the support surface 220, and the support surface 220 is closer to the bottom wall of the receiving groove 110 than the guide surface 230. This arrangement makes the distance between the support surface 220 and the bottom wall of the receiving groove 110 smaller, facilitating the shaping of the aperture structure 300 into an unfolded state, and further ensuring that the axes of the shell through hole 120 and the aperture hole 310 are collinear. The large distance between the guide surface 230 and the bottom wall of the receiving groove 110 facilitates the guidance of the folded portion 330 to the support surface 220 when the driving component 400 drives the aperture structure 300 to move, where it is then unfolded and converted into the unfolded portion 320. The guide surface 230 ensures the smoothness of the aperture structure 300 during unfolding, thereby improving the reliability and flexibility of the aperture structure 300 when switching between different aperture holes 310.

[0076] In some alternative embodiments, such as Figure 6 As shown, the guide surface 230 is provided with a mounting groove 240, such as Figure 4 As shown, the drive unit 400 is installed in the mounting slot 240. By placing the drive unit 400 in the part where the guide surface 230 is located, the problem of the drive unit 400 interfering with the movement of the aperture structure 300 is prevented, so that the drive unit 400 does not occupy the retraction space 210, and therefore does not affect the retraction of the aperture structure 300 in the retraction space 210.

[0077] For example, such as Figure 6 As shown, the support surface 220 is planar, allowing it to better support the unfolded portion 320 of the aperture structure 300, ensuring the aperture hole 310 aligns directly with the through hole 120. Optionally, the guide surface 230 is curved to improve the guiding effect on the aperture structure 300, allowing it to fold or unfold along the curvature of the guide surface 230, reducing the risk of jamming. Furthermore, the shape of the guide surface 230 is identical to the shape of the transition portion from the folded portion 330 to the unfolded portion 320, providing better support for the aperture structure 300. Additionally, by using a curved guide surface 230, the aperture structure 300 can move smoothly at different angles, adapting to various optical scenarios.

[0078] In this embodiment, the support member 200 can provide stable support for the aperture structure 300, preventing the aperture structure 300 from shaking or shifting; and the support surface 220 is flat, so it can be accurately aligned during the folding and unfolding process, ensuring that the optical center is aligned when switching between different aperture holes 310.

[0079] In some alternative embodiments, the portion of the support 200 located on the guide surface 230 may have a built-in sliding guide rail, which can reduce the friction between the aperture structure 300 and the guide surface 230 and improve the structural life of the aperture structure 300.

[0080] In some optional embodiments, the groove wall of the receiving slot 110 forming the folding space 210 is curved to accommodate the shape of the folding portion 330, reducing the risk of the aperture structure 300 getting stuck due to corners, thus providing higher reliability. Figure 7 As shown, in this embodiment, the groove wall of the receiving groove 110 forming the folded space 210 is a curved groove wall 130.

[0081] Optionally, such as Figure 6 As shown, the support surface 220 is provided with a support through hole 250, which is collinear with the axis of the housing through hole 120. By providing the support through hole 250, the support member 200 will not block the housing through hole 120 and the aperture hole 310, allowing light to be transmitted to the lens assembly. Furthermore, the area of ​​the support surface 220 in contact with the aperture structure 300 is increased, improving the effect of supporting the aperture structure 300 and ensuring that the unfolded part 320 supported on the support surface 220 is parallel to the bottom wall of the receiving groove 110.

[0082] In one possible implementation, such as Figure 3 As shown, the driving end 410 of the driving component 400 is connected to a connecting structure 500, and the aperture structure 300 is connected to the connecting structure 500. Since the driving end 410 is typically small, by providing the connecting structure 500, the connection area with the aperture structure 300 can be increased, thereby reducing the risk of connection failure with the aperture structure 300. Exemplarily, the connecting structure 500 includes, but is not limited to, a connecting block or a connecting plate. The connection between the driving end 410 and the connecting structure 500 is a detachable connection, and the connection between the aperture structure 300 and the connecting structure 500 can be either a detachable connection or a fixed connection; this embodiment does not limit this.

[0083] Optionally, the aperture device further includes a position sensing component 600. The position sensing component 600 includes a first sensor 610 disposed on the support member 200 and a plurality of second sensors 620 disposed on the connecting structure 500, with each of the second sensors 620 corresponding one-to-one with a plurality of aperture holes 310. The first sensor 610 can sense any one of the second sensors 620. By setting the position sensing component 600, the accuracy of aperture hole 310 switching can be ensured, the impact of positional and structural deviations of the aperture hole 310 on the image can be reduced, and real-time feedback data can be provided for intelligent control of the camera module.

[0084] Optionally, the first sensing element 610 can be a position sensor (e.g., a Hall sensor), and the second sensing element 620 can be a magnet. The position sensor and the second sensing element 620 cooperate to form a dead-loop control system. For example, when the position sensor is directly opposite one of the second sensing elements 620, the aperture 310 corresponding to that second sensing element 620 is collinear with the axis of the shell through hole 120, generating a signal. When the position sensor is directly opposite another second sensing element 620, the aperture 310 corresponding to that other second sensing element 620 is collinear with the axis of the shell through hole 120, generating another different signal. Based on the different signals generated by the position sensor, it can be determined which aperture 310 is collinear with the axis of the shell through hole 120. Therefore, the controller can determine whether to control the drive element 400 to continue moving based on the signal fed back by the position sensor. It can be seen that the position sensing component 600 provided in this embodiment can monitor the position of the aperture structure 300 relative to the shell 100 in real time and automatically adjust the drive parameters of the drive element 400 to maintain accurate positioning and reduce the position error during the switching process of the aperture 310.

[0085] It should be noted that the sensing principles of the first sensor 610 and the second sensor 620, as well as the specific methods by which the controller controls the driving component 400 to operate according to different signals, can be referred to the prior art, and this embodiment does not limit them.

[0086] Optionally, such as Figure 5 As shown, the aperture device also includes a filter structure 700, which is mounted on the aperture hole 310. The filter structure 700 includes, but is not limited to, an infrared filter. The infrared filter has the function of avoiding stray light to meet the needs of various application scenarios.

[0087] In some alternative embodiments, each aperture 310 is fitted with a filter structure 700. In other embodiments, a portion of the aperture 310 is fitted with a filter structure 700.

[0088] The filter structure 700 provided in this embodiment uses a novel high-efficiency light-transmitting material to reduce distortion and loss of light during transmission.

[0089] The aperture device provided in this embodiment can be applied to the camera module of electronic devices. Through precise control of the aperture structure 300, clearer and brighter images can be obtained, especially in low-light environments. This innovative application of technology not only improves shooting effects but also significantly enhances the shooting performance of the device. Furthermore, the design of the folding space 210 provides a more robust and flexible adjustment scheme for the aperture structure 300, ensuring that the stability of the aperture device remains unaffected during long-term use. It exhibits high stability and flexibility, and also improves the durability of the aperture device, reducing the risk of damage caused by aperture structure 300 adjustment. Through the folding function of the aperture structure 300, its shape change in different states ensures high efficiency and stability in complex operating environments. In addition, the aperture device provided in this embodiment has a simple and efficient structural design, is compatible with existing optical equipment manufacturing processes, and uses materials and structures that are currently feasible and mature technologies, facilitating mass production. Simultaneously, the folding mechanism of the aperture structure 300 has passed preliminary design verification, proving its feasibility in practical operation. By employing a foldable aperture structure with 300 elements, the manufacturing cost of the aperture device is reduced compared to traditional designs. Simultaneously, by improving the adjustment precision and equipment stability of the aperture structure 300, the product return rate caused by inaccurate aperture structure adjustment can be reduced, thus saving on maintenance and replacement costs over long-term use. Compared to traditional designs, the aperture structure 300 in this embodiment offers more stable and efficient adjustment, significantly improving shooting quality in low-light environments while reducing image noise under various lighting conditions.

[0090] Optionally, the aperture structure 300 can be designed with various sizes of circular openings to adjust the amount of light entering the lens according to different shooting needs. The specific size range of the aperture opening 310 is: minimum aperture: 0.5mm; maximum aperture: 16mm. The principle for selecting the specific size is based on the calculation of focal length, depth of field, aperture, and exposure time. Different sizes are suitable for different shooting environments. In low-light environments, a larger aperture (such as 16mm) can increase the amount of light entering and improve the shooting effect. In high-light environments, a smaller aperture (such as 0.5mm) can effectively reduce the amount of light entering and prevent overexposure.

[0091] In this embodiment, the aperture 310 can be a circular aperture, a square aperture, etc., and this embodiment is not limited to this. The aperture 310 is circular in shape, which is suitable for general shooting needs and provides a uniform light intake effect. For special shooting needs, such as bokeh (Bokeh effect), different aperture shapes (e.g., elliptical or polygonal) can be used to adjust the bokeh effect of the image. For special scenes (e.g., environments with strong light refraction or reflection), a polygonal aperture with light dispersion effect can be selected to reduce bokeh as needed.

[0092] In this embodiment, the aperture structure 300 is made of optical-grade plastic (e.g., polycarbonate or PMMA), which provides high light transmittance and durability while reducing surface reflection loss. For applications requiring high optical performance, high-strength aluminum alloy is recommended as the primary material for the aperture structure 300, with an anti-reflective coating applied to its surface to reduce light diffraction and reflection. Under certain specific requirements, using metallic materials (such as titanium alloy) as components of the aperture structure 300 can effectively improve its durability and ensure stability under high-intensity light conditions.

[0093] It should be noted that the aperture device provided in this embodiment can precisely adjust the light: aperture holes 310 of different sizes, shapes, and materials can precisely adjust the amount of light entering the lens assembly according to different shooting scenarios, providing the best shooting effect. The aperture device can also improve optical performance: through anti-reflective coating and precision machining, light loss is reduced, light transmittance is increased, and image quality is enhanced.
