Abstract
Description
Technical Field
[0001] This application relates to the field of camera technology, specifically to a camera module and electronic device. Background Technology
[0002] In most camera modules, the multiple lens components are separate structures, meaning that multiple lens mounts move relative to each other to achieve focusing. However, this separate design results in a large camera module size and relatively poor focusing accuracy. Utility Model Content
[0003] In view of the above, it is necessary to provide a camera module and electronic device to improve focusing accuracy while miniaturizing the device.
[0004] This application provides a camera module, including:
[0005] Photosensitive components;
[0006] A mounting base is provided on the photosensitive side of the photosensitive component and has a mounting through hole;
[0007] The first lens assembly includes a first lens, a first magnet, and a first coil. The first lens is slidably connected to the side wall of the mounting through hole along the optical axis of the first lens. The first magnet is disposed on the first lens, and the first coil is disposed on the fixing base and corresponds to the first magnet in the optical axis direction of the first lens.
[0008] The second lens assembly includes a second lens, a second magnet, and a second coil. The second lens is slidably connected to the side wall of the mounting through hole along the optical axis of the second lens, and the second lens is coaxially arranged with the first lens. The second magnet is disposed on the second lens, and the second coil is disposed on the fixing base and corresponds to the second magnet in the optical axis direction of the second lens.
[0009] When the first coil is energized, the first magnet moves the first lens closer to or further away from the second lens; when the second coil is energized, the second magnet moves the second lens closer to or further away from the first lens.
[0010] In the aforementioned camera module, the first lens and the second lens are slidably connected to the sidewall of the mounting through hole. The first lens can move relative to the fixed base under the action of the first magnet, and the second lens can move relative to the fixed base under the action of the second magnet, thereby achieving focusing of the camera module. This design occupies little space and is conducive to the miniaturization of the camera module. Furthermore, since both the first and second lenses move relative to the fixed base when the camera module is focusing, this helps improve the focusing accuracy of the camera module.
[0011] In some embodiments, the mounting base includes:
[0012] A fixing member is provided on the photosensitive side of the photosensitive component and has the mounting through hole;
[0013] The mounting component is connected to the sidewall of the mounting through hole and is arranged circumferentially along the mounting through hole;
[0014] The first lens and the second lens are located on opposite sides of the mounting component, and the first coil and the second coil are located on opposite sides of the mounting component.
[0015] Therefore, the mounting and fixing components make the mounting base have an H-shaped structure, which isolates the movement space of the first lens and the second lens, avoids interference during the movement of the first lens and the second lens, and helps to improve the accuracy of the movement of the first lens and the second lens.
[0016] In some embodiments, the mounting member has a first mounting groove on the side away from the photosensitive component, and the fixing member has a second mounting groove on the side facing the photosensitive component. The first mounting groove and the second mounting groove are offset in the optical axis direction of the first lens. The first coil is fixedly housed in the first mounting groove, and the second coil is fixedly housed in the second mounting groove.
[0017] Therefore, the installation difficulty of the first and second mounting slots can be reduced. Furthermore, the first and second mounting slots are offset along the optical axis of the first lens, which reduces interference between the first and second coils after energization.
[0018] In some embodiments, a first receiving groove is provided on the outer side of the first lens, and the first receiving groove and the first mounting groove are correspondingly arranged in the optical axis direction of the first lens. The first magnet is fixedly received in the first receiving groove. A second receiving groove is provided on the outer side of the second lens, and the second receiving groove and the second mounting groove are correspondingly arranged in the optical axis direction of the second lens. The second magnet is fixedly received in the second receiving groove.
[0019] Therefore, by fixing the first magnet and the second magnet in the first receiving slot and the second receiving slot respectively, it is possible to avoid the first magnet occupying space outside the first lens and the second magnet occupying space outside the second lens, which is conducive to the miniaturization of the camera module.
[0020] In some embodiments, the mounting base further includes:
[0021] An extension is connected to the side of the fixing member opposite to the photosensitive component and is disposed around the mounting through hole to stop the first lens from being blocked.
[0022] Therefore, the extension can limit the first lens and stop it. In addition, the extension is easy to be clamped by external components to achieve rapid transfer of the mounting base.
[0023] In some embodiments, the fastener, the mounting element, and the extension are an integral structure.
[0024] Therefore, the integrated structure of fasteners, mounting parts and extension parts can reduce the processing difficulty of the mounting base and help reduce the manufacturing cost of the mounting base.
[0025] In some embodiments, there are multiple first coils and multiple first magnets. The multiple first coils are arranged at intervals along the circumference of the mounting base, and the multiple first magnets are arranged at intervals along the outer periphery of the first lens, and correspond one-to-one with the multiple first coils in the optical axis direction of the first lens.
[0026] Therefore, multiple first coils and multiple first magnets can form multiple power points around the first lens, which is beneficial to improving the efficiency of the first lens movement.
[0027] In some embodiments, there are multiple second coils and multiple second magnets. The multiple second coils are arranged at intervals along the circumference of the fixing base, and the multiple second magnets are arranged at intervals along the outer periphery of the second lens, and correspond one-to-one with the multiple second coils in the optical axis direction of the second lens.
[0028] Therefore, multiple second coils and multiple second magnets can form multiple power points around the second lens, which is beneficial to improving the efficiency of the second lens movement.
[0029] In some embodiments, the camera module further includes:
[0030] The limiting seat is held in place on the outer periphery of the photosensitive component and sleeved on the fixing seat.
[0031] Therefore, the limiting seat can improve the positional accuracy of the fixed seat relative to the photosensitive component, which is beneficial to improving the image acquisition stability of the camera module.
[0032] This application also provides an electronic device, including:
[0033] case;
[0034] The aforementioned camera module is mounted on the housing.
[0035] In the camera module of the aforementioned electronic device, the first lens and the second lens are slidably connected to the sidewall of the mounting through hole. The first lens can move relative to the fixed base under the action of the first magnet, and the second lens can move relative to the fixed base under the action of the second magnet, thereby achieving focusing of the camera module. This design occupies little space and is beneficial for the miniaturization of the electronic device. Furthermore, since both the first and second lenses move relative to the fixed base when the camera module is focusing, this improves the focusing accuracy of the camera module and thus enhances the image quality of the electronic device.

[0043] The embodiments of this case will be described in detail below with reference to the accompanying drawings.
[0044] Please see Figure 1 and Figure 2 This application provides a camera module 100, including a photosensitive component 110, a mounting base 120, a first lens assembly 130, and a second lens assembly 140. The mounting base 120 is located on the photosensitive side of the photosensitive assembly 110 and has a mounting through hole 120a. The first lens assembly 130 includes a first lens 131, a first magnet 132, and a first coil 133. The first lens 131 is slidably connected to the side wall of the mounting through hole 120a along the optical axis of the first lens 131. The first magnet 132 is located on the first lens 131. The first coil 133 is located on the mounting base 120 and corresponds to the first magnet 132 in the optical axis direction of the first lens 131. The second lens assembly 140 includes a second lens 141, a second magnet 142, and a second coil 143. The second lens 141 is slidably connected to the side wall of the mounting through hole 120a along the optical axis of the second lens 141, and the second lens 141 is coaxially arranged with the first lens 131. The second magnet 142 is located on the second lens 141. The second coil 143 is located on the mounting base 120 and corresponds to the second magnet 142 in the optical axis direction of the second lens 141. When the first coil 133 is energized, the first magnet 132 causes the first lens 131 to move closer to or away from the second lens 141. When the second coil 143 is energized, the second magnet 142 causes the second lens 141 to move closer to or away from the first lens 131.
[0045] In this embodiment, the first lens 131 is engaged with the side wall of the mounting through hole 120a. When the first coil 133 is energized, the first lens 131 moves relative to the fixed base 120 under the drive of the first magnet 132, thereby achieving a sliding connection between the first lens 131 and the fixed base 120. Correspondingly, the second lens 141 is engaged with the side wall of the mounting through hole 120a. When the second coil 143 is energized, the second lens 141 moves relative to the fixed base 120 under the drive of the second magnet 142, thereby achieving a sliding connection between the first lens 141 and the fixed base 120. In the aforementioned camera module 100, the first lens 131 and the second lens 141 are slidably connected to the side wall of the mounting through hole 120a. The first lens 131 can move relative to the fixed base 120 under the drive of the first magnet 132, and the second lens 141 can move relative to the fixed base 120 under the drive of the second magnet 142, thereby achieving focusing of the camera module 100. This design occupies little space and is beneficial for the miniaturization of the camera module 100. Furthermore, both the first lens 131 and the second lens 141 move relative to the fixed base 120 when the camera module 100 is focusing, which helps to improve the focusing accuracy of the camera module 100.
[0046] Please see Figure 1 and Figure 2 In some embodiments, the mounting base 120 includes a fixing member 121 and a mounting member 122. The fixing member 121 is disposed on the photosensitive side of the photosensitive assembly 110 and has a mounting through hole 120a. The mounting member 122 is connected to the side wall of the mounting through hole 120a and is disposed circumferentially along the mounting through hole 120a. The first lens 131 and the second lens 141 are respectively located on opposite sides of the mounting member 122, and the first coil 133 and the second coil 143 are respectively disposed on opposite sides of the mounting member 122.
[0047] Therefore, the mounting component 122 and the fixing component 121 make the fixing base 120 have an H-shaped structure, which isolates the movement space of the first lens 131 and the second lens 141, avoids interference during the movement of the first lens 131 and the second lens 141, and helps to improve the accuracy of the movement of the first lens 131 and the second lens 141.
[0048] Please see Figure 2 and Figure 3In some embodiments, the mounting member 122 has a first mounting groove 122a on the side facing away from the photosensitive assembly 110, and the fixing member 121 has a second mounting groove 122b on the side facing the photosensitive assembly 110. The first mounting groove 122a and the second mounting groove 122b are offset in the optical axis direction of the first lens 131. The first coil 133 is fixedly housed in the first mounting groove 122a, and the second coil 143 is fixedly housed in the second mounting groove 122b. Therefore, the installation difficulty of the first coil 133 and the second coil 143 can be reduced by using the first mounting groove 122a and the second mounting groove 122b. In addition, the offset arrangement of the first mounting groove 122a and the second mounting groove 122b in the optical axis direction of the first lens 131 can reduce the interference between the first coil 133 and the second coil 143 after being energized.
[0049] Please see Figure 2 and Figure 3 In some embodiments, a first receiving groove 131a is provided on the outer side of the first lens 131, and the first receiving groove 131a and the first mounting groove 122a are correspondingly arranged in the optical axis direction of the first lens 131. The first magnet 132 is fixedly received in the first receiving groove 131a. A second receiving groove 141a is provided on the outer side of the second lens 141, and the second receiving groove 141a and the second mounting groove 122b are correspondingly arranged in the optical axis direction of the second lens 141. The second magnet 142 is fixedly received in the second receiving groove 141a.
[0050] In this embodiment, both the first lens 131 and the second lens 141 are composite structures including lenses and lens barrels.
[0051] Therefore, by fixing the first magnet 132 and the second magnet 142 in the first receiving groove 131a and the second receiving groove 141a respectively, it is possible to avoid the first magnet 132 occupying space outside the first lens 131 and the second magnet 142 occupying space outside the second lens 141, which is beneficial to the miniaturization of the camera module 100.
[0052] Please see Figure 2 In some embodiments, the mounting base 120 further includes an extension 123. The extension 123 connects to the side of the mounting base 121 opposite to the photosensitive assembly 110 and is disposed around the mounting through hole 120a to block the first lens 131.
[0053] Therefore, the extension 123 can limit the first lens 131 and stop the first lens 131. In addition, the extension 123 is easy to be clamped by external components to realize the rapid transfer of the mounting base 120.
[0054] In some embodiments, the fastener 121, the mounting member 122, and the extension member 123 are an integral structure.
[0055] Therefore, the integrated fastener 121, mounting component 122 and extension component 123 can reduce the processing difficulty of the fixed base 120 and help reduce the manufacturing cost of the fixed base 120.
[0056] Please see Figure 2 In some embodiments, there are multiple first coils 133 and multiple first magnets 132. The multiple first coils 133 are arranged at intervals along the circumference of the fixing base 120, and the multiple first magnets 132 are arranged at intervals along the outer periphery of the first lens 131, and correspond one-to-one with the multiple first coils 133 in the optical axis direction of the first lens 131.
[0057] Therefore, multiple first coils 133 and multiple first magnets 132 can form multiple power points around the first lens 131, which is beneficial to improving the efficiency of the movement of the first lens 131.
[0058] In some embodiments, there are multiple second coils 143 and multiple second magnets 142. The multiple second coils 143 are arranged at intervals along the circumference of the fixing base 120, and the multiple second magnets 142 are arranged at intervals along the outer periphery of the second lens 141, and correspond one-to-one with the multiple second coils 143 in the optical axis direction of the second lens 141.
[0059] Therefore, multiple second coils 143 and multiple second magnets 142 can form multiple power points around the second lens 141, which is beneficial to improving the efficiency of the movement of the second lens 141.
[0060] In this embodiment, there are multiple first mounting slots 122a and multiple second mounting slots 122b. Each of the multiple first mounting slots 122a corresponds one-to-one with a multiple first coil 133, and each of the multiple second mounting slots 122b corresponds one-to-one with a multiple second coil 143. Similarly, there are multiple first receiving slots 131a and multiple second receiving slots 141a. Each of the multiple first receiving slots 131a corresponds one-to-one with a multiple first magnet 132, and each of the multiple second receiving slots 141a corresponds one-to-one with a multiple second magnet 142.
[0061] In some embodiments, the camera module 100 further includes a limiting seat 150. The limiting seat 150 is held on the outer periphery of the photosensitive component 110 and sleeved on the fixing seat 120.
[0062] Therefore, the limiting seat 150 can improve the positional accuracy of the fixing seat 120 relative to the photosensitive component 110, which is beneficial to improving the image acquisition stability of the camera module 100.
[0063] Please see Figure 4 This application also provides an electronic device 1000, including a housing 200 and the aforementioned camera module 100, wherein the camera module 100 is mounted on the housing 200. The electronic device 1000 may be a mobile phone, tablet computer, or the like.
[0064] In the camera module 100 of the aforementioned electronic device 1000, the first lens 131 and the second lens 141 are slidably connected to the side wall of the mounting through hole 120a. The first lens 131 can move relative to the fixed base 120 under the drive of the first magnet 132, and the second lens 141 can move relative to the fixed base 120 under the drive of the second magnet 142, thereby achieving focusing of the camera module 100. This design occupies little space and is beneficial for the miniaturization of the electronic device 1000. Furthermore, both the first lens 131 and the second lens 141 move relative to the fixed base 120 when the camera module 100 is focusing, which helps improve the focusing accuracy of the camera module 100 and thus improves the image quality of the electronic device 1000.
