Description

Technical Field

[0001] This application belongs to the field of photography technology, specifically relating to a lens, camera module, and electronic device. Background Technology

[0002] With the widespread use of electronic devices, carrying them while traveling has become a habit for users. Users often use electronic devices to record special and memorable scenes in their daily lives, such as light shows, music festivals, or concerts.

[0003] However, light shows, music festivals, or concerts often feature strong lasers. When these lasers shine on the camera modules of electronic devices, the lens can concentrate the laser energy onto the image sensor, potentially burning it. Summary of the Invention

[0004] This application aims to provide a camera module and electronic device that at least solves one of the problems of existing lenses that easily concentrate laser energy on the photosensitive element, causing the photosensitive element to be burned.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a lens, including: a lens element and a light-shielding assembly, wherein the light-shielding assembly includes: a light-transmitting plate, a grating, and a driving mechanism, wherein...

[0007] The light-transmitting plate is disposed correspondingly to the lens, and a light-transmitting hole is provided at the position opposite to the lens on the light-transmitting plate;

[0008] One side of the grating is fixedly connected to the light-transmitting plate, and the other side of the grating is connected to the driving mechanism, so that the driving mechanism drives the grating to switch between a first state and a second state;

[0009] In the first state, the driving mechanism drives the grating to expand and cover the light-transmitting hole; in the second state, the driving mechanism drives the grating to contract to expose the light-transmitting hole.

[0010] Secondly, embodiments of this application provide a camera module, including: a photosensitive element and the aforementioned lens;

[0011] The photosensitive element is positioned opposite to the lens in the lens and is used to receive the light collected by the lens.

[0012] Thirdly, embodiments of this application also provide an electronic device, including: the lens described above.

[0013] In an embodiment of this application, one side of the grating is fixedly connected to the light-transmitting plate, and the other side is connected to the driving mechanism. Thus, the driving mechanism can drive the other side of the grating to move, allowing the grating to switch between a first state and a second state. In the second state, the driving mechanism can drive the grating to retract, exposing the light-transmitting hole, allowing light to pass through. The lens can then converge the light, enabling the lens to perform its shooting function. In the first state, the driving mechanism drives the grating to unfold and cover the light-transmitting hole. The grating can diffract the light entering the hole, allowing the light collected by the lens to diffuse, thereby preventing the lens from concentrating strong light on the photosensitive element and damaging it, thus protecting the photosensitive element.

[0029] The following is combined Figure 1 - Figure 7 This application describes lenses, camera modules, and electronic devices according to embodiments of the present application.

[0030] like Figure 1As shown, in some embodiments of this application, the lens may specifically include: a lens 1 and a light-shielding assembly 2. The light-shielding assembly 2 includes: a light-transmitting plate 21, a grating 22, and a driving mechanism 23. The light-transmitting plate 21 is correspondingly disposed with the lens 1, and a light-transmitting hole 211 is disposed at a position opposite to the lens 1. One side of the grating 22 is fixedly connected to the light-transmitting plate 21, and the other side of the grating 22 is connected to the driving mechanism 23, so that the driving mechanism 23 drives the grating 22 to switch between a first state and a second state. In the first state, the driving mechanism 23 drives the grating 22 to unfold and cover the light-transmitting hole 211. In the second state, the driving mechanism 23 drives the grating 22 to retract to expose the light-transmitting hole 211.

[0031] In the embodiments of this application, one side of the grating 22 is fixedly connected to the light-transmitting plate 21, and the other side is connected to the driving mechanism 23. Thus, the driving mechanism 23 can drive the other side of the grating 22 to move, allowing the grating 22 to switch between a first state and a second state. In the second state, the driving mechanism 23 can drive the grating 22 to retract, exposing the light-transmitting hole 211, allowing light to pass through. The lens 1 can then focus the light, enabling the lens to capture images. In the first state, the driving mechanism 23 drives the grating 22 to unfold and cover the light-transmitting hole 211. The grating 22 can diffract the light entering the light-transmitting hole 211, allowing the light collected by the lens 1 to diffuse, preventing strong light from concentrating on the photosensitive element 6 and burning it, thus protecting the photosensitive element 6 and improving the user experience.

[0032] The lens 1 described in this embodiment is an important component of the lens, used for transmitting and converging light. Specifically, the lens 1 can be a plastic lens or a glass lens, etc., and can be set according to actual needs. This embodiment does not impose specific limitations on this.

[0033] Specifically, the photosensitive element 6 can be an image sensor. After the lens 1 focuses the light onto the photosensitive element 6, the photosensitive element 6 can perform photoelectric conversion to convert the light signal into an electrical signal. After analog-to-digital conversion and effect adjustment, the final captured image is obtained. Specifically, it can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) device.

[0034] The light-shielding component 2 described in this embodiment may specifically include a light-transmitting plate 21, a grating 22, and a driving mechanism 23. Specifically, the light-transmitting plate 21 may be a plate-shaped structure with light-shielding properties. The light-transmitting plate 21 may be a circular plate, a square plate, a trapezoidal plate, or an irregular plate, etc., and may be set according to actual needs. This embodiment does not make specific limitations in this regard.

[0035] Specifically, a light-transmitting hole 211 may be provided on the light-transmitting plate 21, which is used to transmit light rays incident on the light-transmitting plate 21. The light-transmitting hole 211 may be a through hole cut into the light-transmitting plate 21, or it may be a transparent area set on the light-transmitting plate 21. The specific setting can be made according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0036] Specifically, the light-transmitting hole 211 can be a circular hole, a square hole, a frustum-shaped hole, a trapezoidal hole, or an irregularly shaped hole, etc., and can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0037] Specifically, such as Figure 3 As shown, grating 22 is an optical device composed of a large number of parallel slits of equal width and spacing, which can diffract incident light.

[0038] Furthermore, the grating 22 can be a flexible grating 22, so that the driving mechanism 23 can drive the grating 22 to expand or contract, thereby realizing the switching between the first state and the second state.

[0039] Specifically, weak light (e.g., natural light) has poor directionality and is less affected by diffraction from grating 22; strong light (e.g., laser light) has high concentration and is more affected by diffraction from grating 22. Figure 6 The single spot of the laser beam during incident is shown, such as... Figure 7 The image shows the laser beam after it has been diffracted by grating 22, dispersed into multiple spots in a two-dimensional distribution.

[0040] Specifically, the drive mechanism 23 can be used to provide driving force, and may include a motor, cylinder or electromagnetic component, etc. The specific configuration can be set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0041] Specifically, the number of drive mechanisms 23 can be one, two, three, four, etc., and can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0042] Specifically, one side of the grating 22 is fixedly connected to the light-transmitting plate 21, and the other side is connected to the driving mechanism 23, so that the driving mechanism 23 can drive the other side of the grating 22 to move closer to or further away from the side of the grating 22, thereby enabling the grating 22 to switch between the first state and the second state.

[0043] Specifically, when there is one drive mechanism 23, the drive mechanism 23 can be connected to the center position on the other side of the grating 22; when there are two drive mechanisms 23, the two drive mechanisms 23 can be connected to the two ends on the other side of the grating 22; when there are three drive mechanisms 23, the three drive mechanisms 23 can be evenly connected to the other side of the grating 22.

[0044] Specifically, the driving mechanism 23 can drive the other side of the grating 22 to roll or slide, etc., and can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0045] Specifically, such as Figure 1 and 2 As shown, in the first state, the drive mechanism 23 can drive the other side of the grating 22 away from the grating 22 to move, so that the grating 22 can be unfolded and cover the light-transmitting hole 211. In this state, the grating 22 can diffract the light that is incident on the light-transmitting hole 211, so that the direction of the light exiting the lens can be diffused. In this way, when using the lens to perform a shooting task, the light passing through the lens can be diffused on the photosensitive element 6, avoiding the light from converging on the photosensitive element 6 and burning the photosensitive element 6.

[0046] Specifically, the light-transmitting plate 21 is provided with a light-transmitting hole 211, which can serve as an aperture stop for the lens to control the amount of light entering the lens. When the grating 22 covers the light-transmitting hole 211, the grating 22 can transmit a portion of the light, thus protecting the photosensitive element 6 while retaining a certain degree of photographic capability.

[0047] Specifically, such as Figure 4 and 5 As shown, in the second state, the drive mechanism 23 can drive the other side of the grating 22, which is close to the grating 22, to move, so that the grating 22 can contract and open the light-transmitting hole 211. In this state, the light-transmitting hole 211 can pass light normally. In this way, when using the lens to perform shooting tasks, the lens 1 can focus the light onto the photosensitive element 6, which can improve the shooting effect.

[0048] Furthermore, before entering a bright light environment such as a large light show, music festival, or concert, the user can adjust the grating 22 to the first state to prevent the lens 1 from converging light; after entering a low light environment, the user can adjust the grating 22 to the second state so that the lens 1 can converge light and improve the shooting effect.

[0049] In some optional embodiments of this application, the number of lenses 1 is at least two, and at least two lenses 1 are stacked; the at least two lenses 1 include a first lens and a second lens arranged adjacent to each other; the light-shielding component 2 is disposed between the first lens and the second lens.

[0050] In this embodiment of the application, when the number of lenses 1 includes at least two, the light-shielding component 2 can be arranged between any adjacent first and second lenses, which can improve the diversity and convenience of arranging the light-shielding component 2.

[0051] Specifically, the first lens and the second lens can be any two adjacent lenses 1 from at least two lenses 1.

[0052] Specifically, such as Figure 1 and Figure 4 As shown, the lens includes seven lens elements 1, and from top to bottom, a light-shielding assembly 2 is disposed between the first lens element 1 and the second lens element 1. Further, the light-shielding assembly 2 can also be disposed between the second lens element 1 and the third lens element 1; alternatively, the light-shielding assembly 2 can be disposed between the sixth lens element 1 and the seventh lens element 1. Other possibilities can be found elsewhere. Figure 1 and Figure 4 The embodiments of this application do not specifically limit the settings.

[0053] Specifically, the lens may include a lens barrel 5, which may be sleeved on the lens 1 and fixedly connected to the lens 1, so that the lens barrel 5 can be used to protect and fix the lens 1.

[0054] Specifically, the lens barrel 5 can be a ring structure with a through hole for embedding the lens 1.

[0055] Optionally, at least two lenses 1 can be disposed within a lens barrel 5; the light-blocking assembly 2 can be disposed within the lens barrel 5, and the light-transmitting plate 21 can be fixed circumferentially to the inner wall of the lens barrel 5.

[0056] Optionally, the lens barrel 5 may include a first lens barrel 51 and a second lens barrel 52; the first lens barrel 51 may be sleeved on at least one lens 1; the second lens barrel 52 may be sleeved on at least one lens 1; the light-shielding component 2 may be disposed between the first lens barrel 51 and the second lens barrel 52, and fixedly connected to the first lens barrel 51 and the second lens barrel 52 respectively.

[0057] In this embodiment of the application, the light-shielding component 2 is disposed between the first lens barrel 51 and the second lens barrel 52, which can improve the reliability of fixing the light-shielding component 2.

[0058] Specifically, the light-transmitting plate 21 can be fixedly connected to the first lens barrel 51 and the second lens barrel 52 by means of bonding, welding or bolting, etc. The specific configuration can be set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0059] In some alternative embodiments of this application, the light-shielding component 2 is disposed on one side of the lens 1; in the first state, the grating 22 covers the light-incident side of the lens 1, and the grating 22 is used to change the propagation path of the light entering the lens 1 or to change the propagation path of the light passing through the lens 1.

[0060] In this embodiment, the light-shielding component 2 is disposed on one side of the lens 1, which facilitates the grating 22 to change the propagation path of light, so as to effectively prevent the lens 1 from converging the light together.

[0061] Optionally, the light-shielding component 2 can be disposed below the lens 1, so that the grating 22 can change the propagation path of light passing through the lens 1.

[0062] Specifically, the lens includes a cover plate; the cover plate covers the lens 1 to protect the lens 1; and a light-shielding component 2 is disposed on the side of the lens 1 away from the cover plate.

[0063] Specifically, the cover can be a glass cover or a plastic cover to allow light to pass through. The specific design can be determined according to actual needs, and this application does not impose any specific limitations on this.

[0064] Optionally, the light-shielding component 2 can be positioned above the lens 1, so that the grating 22 can change the propagation path of the light entering the lens 1.

[0065] Specifically, the lens may include a cover plate; the cover plate covers the lens 1 to protect the lens 1; and a light-shielding assembly 2 is disposed between the cover plate and the lens 1.

[0066] In some alternative embodiments of this application, the driving mechanism 23 includes a first magnetic element 231 and a second magnetic element 232; the first magnetic element 231 is fixedly connected to the light-transmitting plate 21; the second magnetic element 232 is fixedly connected to the other side of the grating 22; in a first state, the first magnetic element 231 and the second magnetic element 232 repel each other, and the second magnetic element 232 drives the grating 22 to unfold and cover the light-transmitting hole 211; in a second state, the first magnetic element 231 and the second magnetic element 232 attract each other, and the second magnetic element 232 drives the grating 22 to contract to expose the light-transmitting hole 211.

[0067] In this embodiment, the first magnetic element 231 is fixedly connected to the light-transmitting plate 21, and the second magnetic element 232 is fixedly connected to the other side of the grating 22. When the first magnetic element 231 and the second magnetic element 232 repel each other, the second magnetic element 232 can drive the grating 22 to unfold, so that the grating 22 switches to the first state; when the first magnetic element 231 and the second magnetic element 232 attract each other, the second magnetic element 232 can drive the grating 22 to contract, so that the grating 22 switches to the second state.

[0068] Specifically, the first magnetic component 231 and the second magnetic component 232 can be provided correspondingly. The first magnetic component 231 can be an electromagnet or a coil, etc., to generate a magnetic field when energized; the corresponding second magnetic component 232 can be a magnet, a magnetic metal, or a magnetite, etc.

[0069] Optionally, the first magnetic component 231 can be a magnet, magnetic metal, or lodestone; the corresponding second magnetic component 232 can be an electromagnet or a coil, etc., to generate a magnetic field when energized.

[0070] Optionally, the lens includes a control module and a power supply; the power supply is electrically connected to the first magnetic element 231, and in the first state, the power supply provides a first electrical signal to the first magnetic element 231 to cause the first magnetic element 231 and the second magnetic element 232 to repel each other; in the second state, the power supply provides a second electrical signal to the first magnetic element 231 to cause the first magnetic element 231 and the second magnetic element 232 to attract each other; the control module is electrically connected to the power supply and is used to control the power supply to output the first electrical signal or the second electrical signal.

[0071] In this embodiment, the control module controls the power supply to output a first electrical signal, and the first magnetic element 231 and the second magnetic element 232 can repel each other, allowing the grating 22 to switch to the first state. The control module also controls the power supply to output a second electrical signal, and the first magnetic element 231 and the second magnetic element 232 can attract each other, allowing the grating 22 to switch to the second state. In this embodiment, controlling the electrical signals output by the power supply through the control module is a simple and convenient method.

[0072] Specifically, the first electrical signal can be a positive current and the second electrical signal can be a negative current; or, the first electrical signal can be a negative current and the second electrical signal can be a positive current. The specific settings can be made according to actual needs, and this application embodiment does not impose specific limitations on this.

[0073] For example, such as Figure 2 As shown, when the control module controls the power supply to output a positive current, the first magnetic element 231 drives the second magnetic element 232 away, and the grating 22 unfolds; Figure 4As shown, when the control module controls the power supply to output a negative current, the first magnetic element 231 drives the second magnetic element 232 to move closer, and the grating 22 contracts.

[0074] In some alternative embodiments of this application, the light-shielding component 2 may further include a rotating shaft; the other side of the grating 22 may be fixedly connected to the rotating shaft, and at least a portion of the grating 22 may be wound around the rotating shaft; the driving mechanism 23 is connected to the rotating shaft and can be used to drive the rotating shaft to rotate.

[0075] In this embodiment of the application, the driving mechanism 23 can drive the rotating shaft to rotate. During the rotation of the rotating shaft, the grating 22 can be expanded or contracted, which facilitates the switching of the grating 22 between the first state and the second state.

[0076] Optionally, such as Figure 5 As shown, the light-shielding component 2 also includes a sliding structure, and a sliding track 3 is provided on the light-transmitting plate 21; the driving mechanism 23 is connected to the sliding structure, and the sliding structure is fixedly connected to the other side of the grating 22. The driving mechanism 23 drives the grating 22 to switch between the first state and the second state through the sliding structure; the sliding structure is slidably connected to the sliding track 3.

[0077] In this embodiment, the driving mechanism 23 is connected to the sliding structure, which is fixedly connected to the other side of the grating 22, allowing the driving mechanism 23 to drive the grating 22 to switch between the first state and the second state via the sliding structure. Since the sliding structure slides along the sliding track 3, the reliability of the sliding structure driving the grating 22 is improved, thereby increasing the reliability of the grating 22 switching between the first state and the second state.

[0078] Specifically, the slider can be fixedly connected to the second magnetic component 232, or the second magnetic component 232 and the slider can be made into an integral structure. The specific configuration can be set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0079] Optionally, the sliding track 3 can extend along the direction from one side to the other of the grating 22 to improve the reliability of the grating 22 switching between the first state and the second state.

[0080] Optionally, the sliding track 3 can be a slide rod, and a groove can be provided on the side of the sliding structure opposite to the slide rod; the slide rod can be embedded in the groove, and the slide rod and the groove are slidably connected;

[0081] Alternatively, the sliding structure can be a slider, and the sliding track 3 can be a groove; the slider is embedded in the groove, and the slider is slidably connected to the groove.

[0082] In this embodiment, the concave-convex fit between the slide rod and the groove, or the concave-convex fit between the slider and the groove, can further improve the reliability and stability of the sliding structure slidingly connected to the sliding track 3.

[0083] In some alternative embodiments of this application, the number of drive mechanisms 23 is two, and the other side of the grating 22 includes a first end and a second end opposite to each other; one drive mechanism 23 is connected to the first end, and the other drive mechanism 23 is connected to the second end.

[0084] In this embodiment, one driving mechanism 23 is connected to the first end, enabling the driving mechanism 23 to drive the first end; the other driving mechanism 23 is connected to the second end, enabling the driving mechanism 23 to drive the second end. In this embodiment, the combined action of the two driving mechanisms 23 improves the reliability of the grating 22's expansion or contraction, thereby improving the reliability of the grating 22 switching between the first state and the second state.

[0085] The lens described in this application embodiment has at least the following advantages:

[0086] In an embodiment of this application, one side of the grating is fixedly connected to the light-transmitting plate, and the other side is connected to the driving mechanism. Thus, the driving mechanism can drive the other side of the grating to move, allowing the grating to switch between a first state and a second state. In the second state, the driving mechanism can drive the grating to retract, exposing the light-transmitting hole, allowing light to pass through. The lens can then converge the light, enabling the lens to perform its shooting function. In the first state, the driving mechanism drives the grating to unfold and cover the light-transmitting hole. The grating can diffract the light entering the light-transmitting hole, allowing the light collected by the lens to diffuse, preventing strong light from concentrating on the photosensitive element and burning it, thereby protecting the photosensitive element and improving the user experience.

[0087] Secondly, this application also discloses a camera module, which may include a photosensitive element 6 and the aforementioned lens; the photosensitive element 6 may be disposed opposite to the lens 1 in the lens, for receiving light collected by the lens 1.

[0088] The camera module in this embodiment includes a photosensitive element 6 and a lens, the lens including a lens 1; the photosensitive element 6 is disposed opposite to the lens 1 to receive the light stimulated by the lens 1 and perform photoelectric conversion to realize the shooting function of the camera module.

[0089] The camera module described in this application embodiment has at least the following advantages:

[0090] In an embodiment of this application, one side of the grating is fixedly connected to the light-transmitting plate, and the other side is connected to the driving mechanism. Thus, the driving mechanism can drive the other side of the grating to move, allowing the grating to switch between a first state and a second state. In the second state, the driving mechanism can drive the grating to retract, exposing the light-transmitting hole, allowing light to pass through. The lens can then converge the light, enabling the lens to perform its shooting function. In the first state, the driving mechanism drives the grating to unfold and cover the light-transmitting hole. The grating can diffract the light entering the light-transmitting hole, allowing the light collected by the lens to diffuse, preventing strong light from concentrating on the photosensitive element and burning it, thereby protecting the photosensitive element and improving the user experience.

In the second state, the driving mechanism can drive the grating to retract, exposing the light-transmitting hole, allowing light to pass through. The lens can then converge the light, enabling the camera to capture images. In the first state, the driving mechanism drives the grating to expand and cover the light-transmitting hole.
