For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] Combine the following Figure 1-Figure 3 Describe a camera module and an electronic device according to an embodiment of the present application.

[0035] like Figure 1 As shown, according to some embodiments of the camera module of the present application, the camera module includes a photosensitive member 1 and a laser energy absorption component 2. The laser energy absorption component 2 is arranged on the photosensitive side of the photosensitive member 1. The laser energy absorption component 2 is provided with a laser energy absorption zone, which is arranged corresponding to the light through hole 7 of the camera module, and the laser energy absorption zone is used to absorb the energy of the laser emitted to the photosensitive member 1 through the light through hole 7.

[0036] The camera module further includes a cover plate 3 and a lens 4. The cover plate 3 and the lens 4 are both arranged on the photosensitive side of the photosensitive member 1, and the lens 4 is located between the cover plate 3 and the photosensitive member 1. The photosensitive member 1 is used to receive the light signal gathered by the lens 4 and convert it into an electrical signal. The cover plate 3 is a light-transmitting cover plate. Furthermore, the camera module further includes a bracket 5, and the laser energy absorption component 2 is carried on the bracket 5.

[0037] The laser energy absorption component 2 can be arranged at any position on the photosensitive side of the photosensitive member 1, and the present application does not make any specific limitation, as long as it can ensure that the laser emitted to the photosensitive member 1 through the light hole 7 can reach the laser energy absorption area of ​​the laser energy absorption component 2. For example, the laser energy absorption component 2 is arranged on the side of the cover plate 3 away from the lens 4; or, the laser energy absorption component 2 is arranged between the cover plate 3 and the lens 4; or, Figure 1 As shown, the laser energy absorption component 2 is arranged between the cover plate 3 and the lens 4.

[0038] Since most laser wavelengths (such as the laser wavelength of 632.8nm of helium-neon laser and the laser wavelength of 532nm of green laser pen) are distributed in the visible light band (380-760nm), and the camera module needs to cover the visible light band when imaging, it is impossible to disperse or transfer laser energy. According to the camera module of the embodiment of the present application, by setting a laser energy absorption component 2 on the photosensitive side of the photosensitive element 1, the laser energy absorption component 2 is used to absorb the laser energy emitted to the photosensitive element 1 through the light hole 7, so as to avoid the laser energy from causing burns to the photosensitive element 1, thereby improving the life of the camera module and ensuring the user's shooting experience.

[0039] In some embodiments of the present application, the laser energy absorption component 2 includes a laser energy absorption film, which is arranged on the side of the cover plate 3 away from the photosensitive member 1. The laser energy absorption film is a solid transparent film-like structure, which contains polymers such as quinones and fluorene rings that can absorb laser energy. The laser energy absorption film can be attached to the cover plate 3 by double-sided adhesive or optical adhesive. The laser and visible light are irradiated to the laser energy absorption film at the same time, and the laser energy is weakened after being absorbed by the laser energy absorption film. The visible light and the laser with weakened energy are irradiated to the photosensitive member 1 to prevent the laser energy from causing burns to the photosensitive member 1. When the laser energy absorption film is severely damaged, the laser energy absorption film can be replaced.

[0040] In some embodiments of the present application, the laser energy absorption component 2 includes a frame 21 and a laser energy absorption liquid. A containing cavity is provided in the frame 21, and the containing cavity corresponds to the laser energy absorption zone. The laser energy absorption liquid is contained in the containing cavity. The laser energy absorption liquid contains polymers such as quinones and fluorene rings that can absorb laser energy. At least a part of the area of ​​the frame 21 corresponding to the containing cavity is set as a light-transmitting area. When the laser is irradiated to the light-transmitting area, its energy can be absorbed by the laser absorption liquid in the containing cavity and then weakened, thereby protecting the photosensitive member 1 from being burned by strong light.

[0041] Specifically, the frame 21 includes two flat plates arranged opposite to each other, and the accommodating cavity is formed between the two flat plates. At least the area on the two flat plates corresponding to the light-through hole 7 of the camera module is set as a light-transmitting area. The laser and visible light can simultaneously pass through the light-transmitting area on one flat plate to reach the accommodating cavity, and the laser energy is absorbed by the laser energy absorbing liquid in the accommodating cavity, and then the visible light and the laser with weakened energy continue to pass through the light-transmitting area on the other flat plate to reach the photosensitive member 1.

[0042] In some embodiments of the present application, the laser energy absorption component 2 further includes a liquid storage cavity 203, and the volume of the liquid storage cavity 203 is variable. A sliding member 22 is provided in the accommodating cavity, and the sliding member 22 separates the accommodating cavity into a first cavity 201 and a second cavity 202. The first cavity 201 is connected to the liquid storage cavity 203, and the second cavity 202 is connected to the atmosphere. The laser energy absorption liquid is contained in the first cavity 201.

[0043] The slide member 22 can be switched between a first position and a second position. Figure 2 As shown, when the sliding member 22 is in the first position, the first cavity 201 corresponds to the light-through hole 7. Figure 3 As shown, when the sliding member is in the second position, the second cavity 202 corresponds to the light-through hole 7 .

[0044] The liquid storage cavity 203 is used to store laser energy absorbing liquid. The laser energy absorbing liquid in the accommodating cavity is contained in the first cavity 201. The frame 21 is provided with a liquid inlet 211, which connects the first cavity 201 and the liquid storage cavity 203. Optionally, the liquid inlet 211 is connected to the liquid storage cavity 203 through a pipeline.

[0045] The sliding member 22 may be a rod-shaped structure or a sheet-shaped structure, etc. The side of the sliding member 22 is sealed and connected to the cavity wall of the accommodating cavity, thereby dividing the accommodating cavity into a first cavity 201 and a second cavity 202 that are isolated from each other. In addition, the sliding member 22 can slide relative to the cavity wall of the accommodating cavity, thereby changing the volume of the first cavity 201 and the second cavity 202. The accommodating cavity is provided with an exhaust hole 212, and the exhaust hole 212 is connected to the second cavity 202. When the volume of the first cavity 201 increases, the air in the second cavity 202 is discharged from the exhaust hole 212. When the volume of the first cavity 201 decreases, the second cavity 202 inhales air from the exhaust hole 212. The air pressure in the second cavity 202 is stable, which can ensure the normal sliding of the sliding member 22.

[0046] like Figure 2 As shown, when the sliding member 22 is in the first position, the first cavity 201 is in the maximum volume state, and the first cavity 201 at least covers the area corresponding to the light hole 7. Figure 3As shown, when the sliding member 22 is in the second position, the first cavity 201 is in the minimum volume state, that is, the second cavity 202 is in the maximum volume state, and the second cavity 202 at least covers the area corresponding to the light through hole 7.

[0047] In the embodiment of the present application, the first cavity 201 and the liquid storage cavity 203 are in sealed communication. The volumes of the first cavity 201 and the liquid storage cavity 203 are both variable, and the volumes of the two change in opposite directions, so that the total volume of the first cavity 201 and the liquid storage cavity 203 remains unchanged.

[0048] The driving member can directly drive the sliding member 22 to move between the first position and the second position to change the volume of the first cavity 201. Alternatively, the volume of the first cavity 201 can be changed by changing the volume of the liquid storage cavity 203, so that the laser energy absorbing liquid can flow and transfer between the first cavity 201 and the liquid storage cavity 203.

[0049] Specifically, when the volume of the liquid storage cavity 203 decreases, the laser energy absorbing liquid therein enters the first cavity 201 from the liquid inlet 211, and the sliding member 22 moves to the first position under the action of the liquid pressure. When the volume of the liquid storage cavity 203 increases, the laser energy absorbing liquid in the first cavity 201 is sucked into the liquid storage cavity 203 from the liquid inlet 211, and the sliding member 22 moves to the second position under the action of the gas pressure of the second cavity 202.

[0050] The camera module provided in the present application can take into account shooting in both ordinary scenes and laser scenes. When the camera module works in a laser scene, the volume of the first cavity 201 can be increased by driving the slider 22 to move or reducing the volume of the liquid storage cavity 203 until the first cavity 201 can completely cover the area corresponding to the light hole 7. When the camera module works in an ordinary scene, the volume of the first cavity 201 can be reduced by driving the slider 22 to move or increasing the volume of the liquid storage cavity 203 until the second cavity 202 completely covers the area corresponding to the light hole 7, thereby avoiding the influence of the laser energy absorption component 2 on the imaging.

[0051] The camera module provided in the present application also includes a motor 6, which is connected to the lens barrel and is used to drive the lens 4 to move closer to or farther from the photosensitive element 1. In the case where a laser energy absorbing film is provided, and / or the distribution area of ​​the laser energy absorbing liquid completely covers the area corresponding to the light hole 7, the influence of the laser energy absorbing component 2 on the imaging can be compensated by adjusting the focus of the motor.

[0052] In some embodiments of the present application, the liquid storage cavity 203 is an elastic sac. The volume of the first cavity 201 is changed by sliding the sliding member 22. In other embodiments of the present application, the liquid storage cavity 203 is a rigid body. The laser energy absorption component 2 includes a liquid storage pipe 23 and a piston 24. The liquid storage pipe 23 is connected to the accommodating cavity, and the piston 24 can be slidably disposed in the liquid storage pipe 23 to form the liquid storage cavity 203.

[0053] A liquid storage cavity 203 is formed between the piston 24 and the side wall of the liquid storage pipe 23. When the driving sliding member 22 moves toward the direction close to the liquid inlet 211 to reduce the volume of the first cavity 201, the piston 24 is pushed by the liquid to move away from the liquid inlet 211, thereby increasing the volume of the liquid storage cavity 203. When the driving sliding member 22 moves toward the direction away from the liquid inlet 211 to increase the volume of the first cavity 201, the piston 24 moves toward the direction close to the liquid inlet 211, thereby reducing the volume of the liquid storage cavity 203.

[0054] Furthermore, the laser energy absorption assembly 2 may further include a driving member 25, such as a micro-stepping motor. The driving member 25 is connected to the piston 24. Driven by the driving member 25, the piston 24 can move relative to the liquid storage pipe 23 to change the volume of the liquid storage cavity 203, thereby changing the volume of the first cavity 201.

[0055] When the volume of the first cavity 201 needs to be increased, the piston 24 is driven to move toward the liquid inlet 211 so that the laser energy absorbing liquid in the liquid storage cavity 203 is squeezed into the first cavity 201 from the liquid inlet 211, and the sliding member 22 can move to the first position under the action of the liquid pressure.

[0056] When the volume of the first cavity 201 needs to be reduced, the piston 24 is driven to move away from the liquid inlet 211, so that the laser energy absorbing liquid in the first cavity 201 is sucked back into the liquid storage cavity 203 from the liquid inlet 211, and at the same time, the sliding member 22 can move to the second position under the action of the gas pressure in the second cavity 202.

[0057] In some embodiments of the present application, the sliding member 22 is a first magnet, and the laser energy absorption assembly further includes a second magnet 26. The second magnet 26 is disposed on a side of the second cavity 202 away from the first cavity 201. When at least one of the first magnet and the second magnet 26 is powered on, an attraction or repulsion is generated between the first magnet and the second magnet 26. Among them, at least one of the first magnet and the second magnet 26 is configured as an electromagnet, which has magnetism when powered on, so that an electromagnetic attraction or an electromagnetic repulsion is generated between it and the other magnet. The second magnet 26, as a driving member of the sliding member 22, can change the volume of the first cavity 201 through the electromagnetic force between the second magnet 26 and the sliding member 22.

[0058] Taking the sliding member 22 as a permanent magnet and the second magnet 26 as an electromagnet as a specific example, when the volume of the first cavity 201 needs to be reduced, a current in a first direction is passed through the second magnet 26 to generate an electromagnetic repulsive force between the sliding member 22 and the second magnet 26, and the electromagnetic repulsive force pushes the sliding member 22 to move to the second position, so as to squeeze the laser energy absorbing liquid in the first cavity 201 into the liquid storage cavity 203.

[0059] When it is necessary to increase the volume of the first cavity 201, a second direction current is passed through the second magnet 26 to generate an electromagnetic attraction between the sliding member 22 and the second magnet 26. The electromagnetic attraction attracts the sliding member 22 to move in a direction away from the liquid inlet 211, so that the laser energy absorbing liquid in the liquid storage cavity 203 is sucked into the first cavity 201, thereby pushing the sliding member 22 to move to the first position.

[0060] It should be noted that when the sliding member 22 is set as an electromagnet and the second magnet 26 is set as a permanent magnet, or when the sliding member 22 and the second magnet 26 are both electromagnets, the corresponding current can also be passed through the electromagnet according to similar principles and the required movement direction of the sliding member 22, and the details are not repeated here.

[0061] In some embodiments of the present application, when the volume of the first cavity 201 is increased, in the absence of the driving member 25, the sliding member 22 can be driven to move toward the first position only by the second magnet 26; in the presence of the driving member 25, the piston 24 can be driven to move toward the direction close to the liquid inlet 211 only by the driving member 25; it is also possible to drive the piston 24 to move toward the direction close to the liquid inlet 211 by the driving member 25 while driving the sliding member 22 to move toward the first position by the second magnet 26, so as to compensate for the problem of insufficient driving force of the sliding member 22 driven by the second magnet 26.

[0062] When the volume of the first cavity 201 is reduced, in the absence of the driving member 25, the sliding member 22 can be driven to move to the second position only by the second magnet 26; in the presence of the driving member 25, the piston 24 can be driven to move in the direction away from the liquid inlet 211 only by the driving member 25; it is also possible to drive the sliding member 22 to move to the second position by the second magnet 26 while driving the piston 24 to move in the direction away from the liquid inlet 211 by the driving member 25, so as to compensate for the problem of insufficient driving force of the sliding member 22 driven by the second magnet 26.

[0063] In some embodiments of the present application, the laser energy absorption assembly 2 further includes a guide rod 27, and two guide rods 27 are respectively disposed on both sides of the accommodating cavity. The two ends of the sliding member 22 are respectively slidably connected to the two guide rods 27. Figure 1As shown, the sliding member 22 can be movably mounted on two guide rods 27. The guide rods 27 can play a guiding role during the sliding process of the sliding member 22, which is conducive to the smooth sliding of the sliding member 22 between the first position and the second position, reduces friction, and increases the sliding speed. The sliding member 22 is sealed and connected to the guide rods 27 to ensure the sealing between the first cavity 201 and the second cavity 202.

[0064] The embodiment of the present application also provides an electronic device, which can be an electronic device such as a mobile phone, a tablet computer, a camera, etc. equipped with a camera module. The electronic device includes a housing and a camera module. The camera module is the camera module described in any of the above embodiments, and the camera module is arranged in the housing.

[0065] Furthermore, in the embodiment of the present application, the electronic device further comprises a laser detector. The laser detector is arranged in the housing, and the laser detector faces the same side as the camera module. The laser detector is communicatively connected with the laser energy absorption component.

[0066] For example, the electronic device is a mobile phone, and the camera module and the laser detector are both arranged on the back of the mobile phone housing. When the electronic device uses the camera module to shoot, if the laser detector senses a laser of a certain intensity, the driving member (such as a driving motor or a second magnet 26) of the slider 22 is started to drive the slider 22 to move to the first position, and / or the driving member 25 of the piston 24 is started to drive the piston 24 to move in a direction close to the liquid inlet 211, so as to increase the volume of the first cavity 201, so that the first cavity 201 covers the corresponding area of ​​the light hole. After shooting, the driving member (such as a driving motor or a second magnet 26) of the slider 22 is started to drive the slider 22 to move to the second position, and / or the driving member 25 of the piston 24 is started to drive the piston 24 to move in a direction away from the liquid inlet 211, so as to reduce the volume of the first cavity 201, so that the second cavity 202 covers the corresponding area of ​​the light hole.
