Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and in particular to a periscope lens and a camera module that are easy to assemble automatically. Background Art

[0002] Most camera modules of existing mobile terminal devices have a zoom function, which can make the image clearer. In order to increase the zoom ratio, the optical axis length of the camera module is relatively long. On this basis, in order to keep the mobile terminal device thin and light, it is necessary to fold the optical axis of the camera module to shorten the size of the camera module in the optical axis length direction. This camera module with a folded optical axis is a periscope camera module.

[0003] At present, the existing periscope camera module designs the optical axis horizontally and rotates the optical axis 90° through a prism to achieve the purpose of folding the optical axis. However, in this solution, since there is a ball fulcrum at one end of the prism to support the prism to rotate up and down and left and right to achieve the purpose of anti-shake, during the assembly process of the prism, the prism, prism seat, spring clip and other components need to be installed at a certain angle and direction, and the installation path is relatively complicated, and automated assembly cannot be achieved, which leads to low production efficiency and reduced product yield, which invisibly increases production costs.

[0035] See also Figure 1 , Figure 1 A schematic diagram of the exploded structure of a periscope lens that is convenient for automated assembly provided in one embodiment of the present invention.

[0036] In order to solve the technical problem that the prism of a conventional periscope lens cannot be assembled automatically, or to achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a periscope lens that is easy to assemble automatically. Figure 1As shown in FIG. 1 , the periscope lens for facilitating automated assembly comprises a base 10, a prism member 20, a lens member 30 and a disassembly member 40. The base 10 has a first opening 11 and a second opening 12 opposite to each other.

[0037] The prism member 20 is disposed in the base 10 and is close to the first opening 11. In a specific implementation, the prism member 20 can be installed in the base 10 in a horizontal or vertical direction through the first opening 11.

[0038] When light and images are input into the lens, the prism component 20 can refract the light and images, thereby folding the optical axis and shortening the length of the optical axis. The prism component 20 is movably connected to the base 10. Specifically, the prism component 20 can rotate at a certain angle in the up-down and / or left-right directions relative to the base 10 to improve the anti-shake ability of the lens, thereby improving the imaging quality.

[0039] The lens component 30 is disposed in the base 10. The lens component 30 is located between the prism component 20 and the second opening 12, and the lens component 30 and the prism component 20 are on the same optical axis. After the image is refracted by the prism component 20, the image passes through the lens component 20 and then is emitted through the second opening 12 and projected onto the optical sensor to complete the shooting and imaging. Further, the lens component 30 is movably connected to the base 10, that is, the lens component 30 can move relative to the prism component 20 along the optical axis direction, and the zoom function is achieved by adjusting the distance between the lens component 30 and the prism component 20.

[0040] On the basis of the above, the disassembly member 40 is movably connected to the first opening 11. Specifically, the disassembly member 40 is detachably connected to the first opening 11. When the disassembly member 40 is connected to the first opening 11 and fixed to the base 10, the disassembly member 40 can close the first opening 11. At this time, the disassembly member 40 is movably connected to the prism member 20. In a specific implementation, the prism member 20 can be installed in the base 10 in a horizontal or vertical direction through the first opening 11. After the prism member 20 is installed, the first opening 11 is closed by the disassembly member 40 to complete the overall assembly.

[0041] By opening the first opening 11 on the base 10, the prism component 20 can be installed flatly in the base 10 in a horizontal or vertical direction through the first opening 11. The horizontal or vertical installation direction can be directly introduced into the automated production assembly, avoiding the embarrassing situation that the conventional periscope lens needs to be installed at an inclined angle and cannot achieve automated production. It can greatly improve production efficiency and reduce production costs, and the automated assembly method can also improve the overall yield of the product.

[0042] Please combine Figure 1 See also Figure 2In some preferred embodiments, as shown in the figure, a plurality of welding parts 50 are respectively provided at both ends of the disassembly part 40. In specific implementation, when the disassembly part 40 is installed on the first opening 11, the plurality of welding parts 50 are respectively connected to the two ends of the first opening 11, and the welding parts 50 are fixed to the two ends of the first opening 11 by laser or melting (conventional technical means), so that the disassembly part 40 is firmly fixed on the first opening 11.

[0043] Preferably, the number of the welding portions 50 is at least four, so as to improve the strength and stability between the detachable component 40 and the first opening 11 .

[0044] Of course, in some other embodiments, reinforcing ribs (not shown) may be provided on the disassembly member 40. When the disassembly member 40 is installed on the first opening 11, the reinforcing ribs are embedded in the side walls at both ends of the first opening 11 to improve the overall strength of the base 10.

[0045] Furthermore, please combine Figure 1 See also Figure 3 The periscope lens for facilitating automated assembly may further include a soft board 60. The soft board 60 is attached to the base 10. Specifically, the soft board 60 is attached to the outer side walls of the base 10 and the disassembly member 40, and exposes the second opening 12. The soft board 60 has pins 70 for connecting power and signals.

[0046] Please combine Figure 1 , Figure 3 See also Figure 4 In some preferred embodiments, the prism component 20 includes a prism seat 21 and a prism 22. The prism seat 21 is movably connected to the base 10. The prism 22 is arranged on the prism seat 21. In a specific implementation, first magnets 80 are respectively embedded on both sides of the prism seat 21, and a first coil 90 is provided at a position corresponding to the first magnet 80 on the soft board 60. The first coil 90 is electrically connected to the soft board 60. When the first coil 90 is energized, a magnetic field can be generated, and the generated magnetic field acts on the first magnet 80, pushing the prism seat 21 to rotate in the left and right directions relative to the base 10, thereby driving the prism 22 to rotate in the left and right directions at a certain angle, thereby achieving the purpose of anti-shake and improving the imaging quality.

[0047] On the basis of the above, a second magnet 100 is provided at the bottom of the prism seat 21, and a second coil 110 is provided at a position corresponding to the second magnet 100 on the soft board 60. The second coil 110 is electrically connected to the soft board 60. When the second coil 110 is energized, a magnetic field can be generated, and the generated magnetic field acts on the second magnet 100, pushing the prism seat 21 to rotate in the up-down direction relative to the base 10, thereby driving the prism 22 to rotate in the up-down direction at a certain angle, thereby achieving anti-shake and improving the imaging quality.

[0048] It should be noted that in order to accurately monitor and control the rotation angle of the prism seat 21 and the prism 22 up and down or left and right, a sensor IC (not shown in the figure) can be set on the first coil 90 and the second coil 110. The sensor IC can accurately read and control the rotation angle of the prism seat 21 and the prism 22 to improve the accuracy of anti-shake and avoid image blur caused by poor anti-shake accuracy.

[0049] Please combine Figure 3 , Figure 4 See also Figure 5 In some preferred embodiments, as shown in the figure, a ball pit 120 is provided on the side of the prism seat 21 facing the disassembly part 40. A ball 130 is arranged in the ball pit 120. When the ball 130 is placed in the ball pit 120, the ball 130 protrudes from the ball pit 120. In specific implementation, the ball 130 forms a rolling connection with the ball pit 120 and the disassembly part 40 respectively. When the first coil 90 and / or the second coil 110 are energized to generate a magnetic field, the generated magnetic field acts on the first magnet 80 and / or the second magnet 100, and the prism seat 21 can use the ball 130 as a support point, so that the prism seat 21 can rotate a certain angle in the up-down and / or left-right direction, thereby driving the prism 22 to rotate a certain angle in the up-down and / or left-right direction, thereby achieving the purpose of anti-shake and improving the imaging quality.

[0050] It is understandable that the ball pit 120 is located at the center point of the surface of the prism seat 21 facing the disassembly component 40 to ensure the balance of the prism seat 21 during the anti-shake operation.

[0051] On the basis of the above, a spring piece 140 is provided on the side of the prism seat 21 facing the disassembly and assembly part 40. In specific implementation, the first connecting parts 141 are respectively provided at the upper and lower ends of the spring piece 140. The first connecting part 141 is connected to the prism seat 21, thereby fixing the spring piece 140 on the prism seat 21. The left and right ends of the spring piece 140 are respectively provided with second connecting parts 142. The second connecting parts 142 protrude from the left and right ends of the prism seat 21 respectively, and are connected to the two ends of the first opening 11, thereby fixing the spring piece 140 on the first opening 11. When the first coil 90 and / or the second coil 110 are energized to generate a magnetic field, the generated magnetic field acts on the first magnet 80 and / or the second magnet 100, and drives the prism seat 21 and the prism 22 to rotate up and down and / or left and right at a certain angle, the spring piece 140 can provide a reset force for the prism seat 21, and at the same time make the rotation of the prism seat 21 more linear, which is conducive to the normal realization of the anti-shake function.

[0052] It should be noted that the first connection portion 141 and the prism seat 21, and the second connection portion 142 and both ends of the first opening 11 can be fixed by riveting, welding, etc., as long as the spring piece 140 can be stably connected to the prism seat 21 and the first opening 11, and this is not limited in this case.

[0053] In some preferred embodiments, the lens component 30 includes a lens 31. The lens 31 is movably connected to the base 10, that is, the lens 31 can move relative to the prism component 20 along the optical axis, and the distance between the lens 31 and the prism 22 is adjusted to achieve a zoom function. Furthermore, the lens 31 and the prism 22 are on the same optical axis, so that the image can be accurately projected into the lens 31 after being refracted by the prism 22, and then projected onto the optical sensor along the second opening 12 to complete the shooting and imaging.

[0054] On the basis of the above, a third magnet 150 is embedded on the side wall of the lens 31. A third coil 160 is provided on the soft board 60 at a position corresponding to the third magnet 150. The third coil 160 is embedded in the side wall of the base 10 and is electrically connected to the soft board 60. When the third coil 160 is energized, a magnetic field can be generated, and the generated magnetic field acts on the third magnet 150, pushing the lens 31 to move relative to the base 10 along the optical axis direction, thereby driving the lens 31 to move along the optical axis direction, adjusting the distance between the lens 31 and the prism 22, so as to realize the zoom function and achieve the purpose of improving the imaging quality.

[0055] Similarly, in order to accurately monitor and control the displacement of the lens 31 on the optical axis, a sensor IC can be set on the third coil 160 to accurately read and control the displacement of the lens 31 to improve the accuracy of zooming and avoid image blurring caused by poor zooming accuracy.

[0056] Preferably, the lens member 30 further includes a slide bar 32. In the illustrated embodiment, there are two slide bars 32, which are respectively horizontally arranged between the lens 31 and the base 10 and located on the left and right sides of the lens 31. The lens 31 is slidably connected to the slide bar 32, and when the third coil 160 is energized to push the lens 31 to move along the optical axis, the slide bar 32 can provide guidance for the lens 31.

[0057] Please combine Figure 2 See also Figure 6In some preferred embodiments, a plurality of glue injection grooves 170 are provided on the base 10 near the first opening 11, and the plurality of glue injection grooves 170 are respectively distributed on the bottom and the inner side walls of both sides of the base 10. After the prism component 20 is installed in the base 10 from the first opening 11 in a horizontal or vertical installation direction, damping glue is injected into the plurality of glue injection grooves 170 to achieve connection between the base 10 and the prism component 20 from multiple angles and directions, thereby improving the stability of the installation of the prism component 20. It is understandable that the damping glue is elastic, and can ensure that the connection between the base 10 and the prism component 20 is stable, and the prism component 20 can be rotated relative to the base 10 in the up-down and / or left-right directions to achieve the purpose of anti-shake.

[0058] In some preferred embodiments, the periscope lens for facilitating automated assembly may further include an upper cover 180. In specific implementation, the upper cover 180 covers the base 10. The upper surface of the upper cover 180 has a third opening 190. The third opening 190 is located directly above the prism 22, so that the image can be projected into the prism 22 through the third opening 190.

[0059] Please combine Figure 1 See also Figure 7A-7C In some preferred embodiments, the present invention further provides an assembly method, as shown in the figure, the assembly method comprises the following steps:

[0060] S1: Install the ball 130 and the spring 140 on the prism component 20, and firmly fix the spring 140 on the prism component 20 through the two first connecting parts 141, so as to complete the complete assembly of the prism component 20;

[0061] S2: Install the fully assembled prism member 20 in the base 10 in a horizontal or vertical direction through the first opening 11, and fix the two second connecting parts 142 to the two ends of the first opening respectively;

[0062] S3: injecting damping glue into the plurality of glue injection grooves 170 respectively to bond the prism member 20 and the base 10;

[0063] S4: Connect the disassembly component 40 and the first opening 11 to each other to close the first opening 11, and weld the welding part 50 to both ends of the first opening 11 by laser or melting to complete the overall automated assembly.

[0064] In some preferred embodiments, the present invention also provides a camera module, comprising the above-mentioned periscope lens that is easy to assemble automatically.

[0065] To sum up, the present invention provides a periscope lens and camera module that are easy to assemble automatically. Compared with the prior art, a first opening is opened on the base, so that the prism component can be installed into the base in a horizontal or vertical direction through the first opening, and the straight installation direction can be directly introduced into the automated production assembly, avoiding the embarrassing situation that the conventional periscope lens needs to be installed at an inclined angle and cannot realize automated production, which can greatly improve production efficiency and reduce production costs, and the automated assembly method can also improve the overall yield of the product.
