Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a camera module and electronic equipment. Background Art

[0002] Cameras are an indispensable functional component in target electronic devices. For example, mobile phones, tablets, smart watches and other electronic devices can be equipped with a certain number of cameras.

[0003] In the prior art, taking mobile phones as an example, some mobile phones have replaced the rear camera with a retractable large aperture camera, replacing the multi-camera module with a single camera. When the retractable large aperture camera is protruding, it is much thicker than the phone itself, but after the lens is retracted, the entire camera module is "retracted" into the body, and the protruding part is not obvious. This meets the consumer's pursuit of extreme lightness and performance of smartphones.

[0004] However, the camera module is prone to wear during the extension and retraction of the lens and is easily damaged after a collision. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a camera module and an electronic device that can solve the problem in the prior art that the camera module is easily worn during the extension and retraction process and is easily damaged after a collision.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a camera module, including a mounting housing, a lens barrel assembly, a guide assembly, and a lens;

[0008] The mounting housing is provided with an accommodating cavity, the lens barrel assembly is at least partially located in the accommodating cavity, the mounting housing and the lens barrel assembly are movably connected via the guide assembly, the guide assembly is used to limit the movable track of the lens barrel assembly, the lens is mounted on the lens barrel assembly, wherein a photosensitive chip is arranged in the accommodating cavity, and the lens barrel assembly drives the lens to approach or move away from the photosensitive chip;

[0009] The guide assembly includes a guide groove and a guide column, the guide groove and the guide column are slidably connected, one of the guide groove and the guide column is arranged on the mounting shell, and the other is arranged on the lens barrel assembly; wherein the guide groove is filled with an anti-collision liquid, and the anti-collision liquid can be used to buffer the guide column to reduce the impact damage of the lens barrel assembly.

[0010] In a second aspect, an embodiment of the present application provides an electronic device, comprising a camera module as described above.

[0011] In the embodiment of the present application, the mounting housing and the lens barrel assembly are two main parts that provide telescopic functions in the camera module. With the cooperation of the guide assembly, the mounting housing and the lens barrel assembly can slide relative to each other along a preset track, and different positions in the preset track will correspond to different telescopic positions in the mounting housing and the lens barrel assembly. The guide groove and the guide column in the guide assembly can cooperate to guide the sliding track between the mounting housing and the lens barrel assembly. When the guide groove is filled with anti-collision liquid, the part of the guide column extending into the guide groove can be in a semi-suspended state. Under the action of the anti-collision liquid, the direct friction between the guide column and the guide groove can be reduced, thereby reducing fatigue wear with the guide groove. And when the camera module falls and is hit, the damage to the guide column can be reduced under the action of the anti-collision liquid, thereby improving the safety of the camera module. The embodiment of the present application has the beneficial effect of reducing fatigue wear of the camera module during the telescopic process and reducing impact damage.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The camera module and electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0023] See also Figures 1 to 6 , an embodiment of the present application provides a camera module, including a mounting housing 10, a lens barrel assembly 20, a guide assembly 30 and a lens 41;

[0024] The mounting housing 10 is provided with an accommodating cavity, the lens barrel assembly 20 is at least partially located in the accommodating cavity, the mounting housing 10 and the lens barrel assembly 20 are movably connected via the guide assembly 30, the guide assembly 30 is used to limit the moving track of the lens barrel assembly 20, the lens 41 is mounted on the lens barrel assembly 20, wherein a photosensitive chip is arranged in the accommodating cavity, and the lens barrel assembly 20 drives the lens 41 to approach or move away from the photosensitive chip;

[0025] The guide assembly 30 includes a guide groove 31 and a guide column 32, and the guide groove 31 and the guide column 32 are slidably connected. One of the guide groove 31 and the guide column 32 is arranged on the mounting shell 10, and the other is arranged on the lens barrel assembly 20; wherein, the guide groove 31 is filled with an anti-collision liquid, and the anti-collision liquid can be used to buffer the guide column 32 to reduce the impact damage of the lens barrel assembly 20.

[0026] In the embodiment of the present application, the mounting housing 10 and the lens barrel assembly 20 are two main parts that provide telescopic functions in the camera module. With the cooperation of the guide assembly 30, the mounting housing 10 and the lens barrel assembly 20 can slide relative to each other along a preset track, and different positions in the preset track will correspond to different telescopic positions in the mounting housing 10 and the lens barrel assembly 20. The lens 41 is provided for light transmission and transmitting light to the photosensitive chip. The guide groove 31 and the guide column 32 in the guide assembly 30 can cooperate to guide the sliding track between the mounting housing 10 and the lens barrel assembly 20. When the guide groove 31 is filled with anti-collision liquid, the part of the guide column 32 extending into the guide groove 31 can be in a semi-suspended state. Under the action of the anti-collision liquid, the direct friction between the guide column 32 and the guide groove 31 can be reduced, thereby reducing fatigue wear with the guide groove 31. And when the camera module falls and is hit, the damage of the guide column 32 can be reduced under the action of the anti-collision liquid, thereby improving the safety of the camera module. The embodiments of the present application have the beneficial effects of reducing fatigue wear of the camera module during the extension and retraction process and reducing impact damage.

[0027] It should be noted that the above-mentioned preset track corresponds to the guide line of the guide groove 31, and the corresponding preset track can be set by setting the guide groove 31 of different shapes. During the relative sliding process of the guide groove 31 and the guide column 32, there can be areas with different slopes, which can specifically include a lens telescopic area and a focal length adjustment area.

[0028] It should be noted that one of the mounting shell 10 and the lens barrel assembly 20 can rotate driven by a gear, and the other is relatively fixed, so that the mounting shell 10 and the lens barrel assembly 20 can rotate relative to each other, and then under the guidance of the guide assembly 30, the mounting shell 10 and the lens barrel assembly 20 can rotate relative to each other and slide relative to each other at the same time, thereby realizing the telescopic function in the camera module.

[0029] Optionally, in an embodiment of the present application, there is a first sealing area between the mounting housing 10 and the lens barrel assembly 20, the guide groove 31 and the guide column 32 are both located in the first sealing area, and the anti-collision liquid is filled in the first sealing area;

[0030] Alternatively, there is a second sealing area between the guide groove 31 and the guide column 32, and the anti-collision liquid is filled in the second sealing area;

[0031] Alternatively, a buffer member 310 is disposed inside the guide groove 31 , a sealing cavity is disposed inside the buffer member 310 , the sealing cavity is filled with the anti-collision liquid, and the guide column 32 is indirectly slidably connected to the guide groove 31 through the buffer member 310 .

[0032] In the embodiments of the present application, three methods of filling the anti-collision liquid are introduced above. The first method is large-scale filling. Specifically, the anti-collision liquid can be directly filled between the mounting shell 10 and the lens barrel assembly 20 so that part of the anti-collision liquid is filled in the guide groove 31. At this time, a first sealing area can be set between the mounting shell 10 and the lens barrel assembly 20. Since the guide groove 31 is in the sealing area and the anti-collision liquid is filled in the sealing area (the anti-collision liquid must also be filled into the guide groove 31 at this time), the effect of reducing impact damage in the present application can be achieved. The second is medium-range filling, specifically, a second sealing area can be set between the guide groove 31 and the guide column 32, and the anti-collision liquid is filled in the second sealing area, and the second sealing area will limit the filling range of the anti-collision liquid to between the guide groove 31 and the guide column 32; the third station is a small-range filling, and specifically, a corresponding accommodating cavity, that is, the buffer 310 in the present application is set in the guide groove 31 according to needs, and the buffer 310 is independent of the guide groove 31 and the guide column 32, and the guide groove 31 and the guide column 32 can be disassembled or replaced as needed, and the anti-collision liquid can be confined in the buffer 310, so that the anti-collision liquid can be filled through the accommodating cavity, and the buffer 310 can be a flexible cavity, and a movable guide rail 313 can be set on the flexible cavity as needed, and the guide rail 313 corresponds to the guide column 32.

[0033] Optionally, in an embodiment of the present application, the buffer member 310 includes a movable structure 311 and a cavity structure 312, the movable structure 311 is movably connected relative to the cavity structure 312, the cavity structure 312 is fixedly connected to the inner wall of the guide groove 31, wherein the sealed cavity is located in the accommodating structure 312;

[0034] The movable structure 311 is provided with a guide rail 313 . The movable structure 311 can drive the guide rail 313 to move relative to the guide groove 31 . The guide column 32 is adapted to the guide rail 313 .

[0035] In the embodiment of the present application, the buffer 310 is used to wrap the anti-collision liquid, and the buffer 310 and the corresponding anti-collision liquid jointly fill the guide groove 31. Among them, the setting of the movable structure 311 can drive the guide rail 313 to move to ensure that the guide column 32 can slide relative to the guide groove 31. The setting of the cavity structure 312 can fix the buffer 310 in the guide groove 31 to prevent the buffer 310 from detaching from the guide groove 31. The containing structure 312 can make the fixation of the buffer 310 more stable and reliable while accommodating the anti-collision liquid.

[0036] Optionally, in an embodiment of the present application, the movable structure 311 is configured as a conveyor belt structure, and the conveyor belt structure is integrally provided with the guide rail 313 .

[0037] In the embodiment of the present application, the setting of the conveyor belt structure can be achieved by a transmission sliding manner so that the movable structure 311 slides relative to the cavity structure 312. After the conveyor belt structure and the guide rail 313 are set as one body, the conveyor belt structure and the guide rail 313 can be moved, and the guide column 32 can slide relative to the guide groove 31.

[0038] It should be noted that the guide rail 313 can also be set as a movable recessed portion as needed. When the guide column 32 moves relative to the buffer 310, the position of the recessed portion also changes accordingly. At this time, the recessed portion can be formed by the guide column 32 squeezing the buffer 310. The change in the squeezing position drives the change in the position of the recessed portion. In this way, there is no need for a corresponding movable structure 311, thereby simplifying the buffer 310.

[0039] Optionally, in an embodiment of the present application, a first resistance wire 314 is provided in the anti-collision liquid, and the first resistance wire 314 is used to change the state of the anti-collision liquid;

[0040] When the first resistance wire 314 is powered off, the anti-collision liquid in the buffer 310 is in a saturated state;

[0041] When the first resistance wire 314 is energized, the anti-collision liquid in the buffer 310 is in an oversaturated state.

[0042] In the embodiment of the present application, the first resistance wire 314 can be set to change the state of the anti-collision liquid. Specifically, the density of the anti-collision liquid can be changed under the action of electrochemistry, so that the anti-collision liquid in the buffer 310 can be switched between a saturated state and an oversaturated state. Specifically, when the first resistance wire 314 is powered off, the anti-collision liquid in the buffer 310 is in a saturated state, and the relative sliding between the guide column 32 and the guide groove 31 is relatively stable; when the first resistance wire 314 is powered on, the anti-collision liquid in the buffer 310 is in an oversaturated state, and the buoyancy of the anti-collision liquid on the guide column 32 is relatively increased, which can further reduce the impact on the guide column 32, avoid direct collision between the guide column 32 and the guide groove 31, and prevent the guide column 32 from breaking due to severe collision.

[0043] Optionally, in an embodiment of the present application, the first resistance wire 314 is connected to the gravity sensor, and the first resistance wire 314 is powered off under normal conditions; when the camera module falls and is impacted, the first resistance wire 314 is powered on under detection by the gravity sensor.

[0044] In the embodiment of the present application, the gravity sensor is set to promptly energize the first resistor 314 when a gravity anomaly occurs in the camera module, thereby causing the anti-collision fluid in the buffer 310 to become supersaturated. At this time, the buoyancy of the anti-collision fluid on the guide column 32 is relatively increased, which can further reduce the impact on the guide column 32, avoid direct collision between the guide column 32 and the guide groove 31, and prevent the guide column 32 from breaking due to severe collision.

[0045] Optionally, in an embodiment of the present application, the guide column 32 is a deformable structure, the deformable structure includes a deformable portion 321 and a filling portion 322, the deformable portion 321 wraps the filling portion 322, and the filler in the filling portion 322 is a flexible protective body;

[0046] The flexible protective body can switch between an expanded state and a contracted state. When the guide groove 31 and the guide column 32 slide relative to each other, the flexible protective body is in the expanded state; when the camera module falls and is hit, the flexible protective body switches from the expanded state to the contracted state.

[0047] In the embodiment of the present application, after the guide column 32 is set as a deformable structure, the hardness of the guide column 32 can be changed as needed, so that the guide column 32 becomes soft in the event of a collision. The soft guide column 32 plays a double protection role in the guide groove 31 filled with anti-collision fluid, further preventing the guide column 32 from being broken by collision.

[0048] Optionally, in an embodiment of the present application, a second resistance wire 323 is provided in the flexible protective body, and the second resistance wire 323 is used to change the state of the flexible protective body;

[0049] When the second resistance wire 323 is energized, the flexible protective body is in an expanded state, and the hardness of the deformation portion 321 is higher than a preset hardness;

[0050] When the second resistance wire 323 is powered off, the flexible protective body is in a contracted state, and the hardness of the deformation portion 321 is lower than a preset hardness.

[0051] In the embodiment of the present application, the second resistance wire 323 can be set to change the state of the flexible protective body. Specifically, the density of the flexible protective body can be changed by thermal or electrochemical expansion or contraction, so that the flexible protective body in the buffer 310 can switch between the expanded state and the contracted state. Specifically, when the second resistance wire 323 is powered on, the flexible protective body in the deformation part 321 is in the expanded state, and the guide column 32 at this time will have sufficient hardness (higher than the preset hardness), so that the relative sliding between the guide column 32 and the guide groove 31 is relatively stable; when the second resistance wire 323 is powered off, the flexible protective body in the deformation part 321 is in the contracted state, and the hardness of the guide column 32 at this time will be lower than the preset hardness, and the guide column 32 will become softer, further reducing the impact on the guide column 32, avoiding damage to the guide column 32 due to collision, and preventing the guide column 32 from breaking due to severe collision.

[0052] It should be noted that the flexible protective body of the present application can be set to liquid, gas or gas-liquid mixture as needed, as long as the filler can change the hardness of the guide column 32 by expansion or contraction.

[0053] It should be noted that the preset hardness of the present application is a relative hardness parameter, which can be changed according to the specific needs of use. When the hardness of the guide column 32 is higher than or equal to the preset hardness, the relative sliding between the guide column 32 and the guide groove 31 is relatively stable, and there will not be too much shaking; when the hardness of the guide column 32 is lower than the preset hardness, the guide column 32 will be relatively soft and will not be seriously damaged.

[0054] Optionally, in an embodiment of the present application, the second resistance wire 323 is connected to the gravity sensor, and the second resistance wire 323 is energized when the camera module is in use; when the camera module falls and is impacted, the second resistance wire 323 is de-energized under the detection of the gravity sensor.

[0055] In the embodiment of the present application, the gravity sensor can be set to timely cut off the power of the second resistance wire 323 when the camera module has abnormal gravity (the second resistance wire 323 is powered when the camera module is in use), so that the anti-collision fluid changes from the expansion state to the contraction state. At this time, the guide column 32 will become softer, which can further reduce the impact on the guide column 32, avoid the direct collision between the guide column 32 and the guide groove 31, and prevent the guide column 32 from breaking due to severe collision. In addition, after the collision, the second resistance wire 323 in the guide column 32 can be powered on again, so that the flexible guide column 32 expands again and resumes the working state.

[0056] Optionally, in an embodiment of the present application, the mounting housing 10 is a fixed bracket, the lens barrel assembly 20 is a sliding bracket, and three groups of the guide grooves 31 and the guide posts 32 are provided.

[0057] In the embodiment of the present application, the provision of three sets of guide assemblies 30 can make the relative sliding of the mounting housing 10 and the lens barrel assembly 20 more stable and reliable, and reduce the occurrence of skew or shaking.

[0058] An embodiment of the present application also provides an electronic device, comprising the camera module as described above.

[0059] In the embodiment of the present application, the electronic device with the above-mentioned camera module can reduce the fatigue wear of the camera module during the telescopic process and reduce the impact damage. The mounting housing 10 and the lens barrel assembly 20 are two main parts that provide the telescopic function in the camera module. With the cooperation of the guide assembly 30, the mounting housing 10 and the lens barrel assembly 20 can slide relative to each other along the preset track, and different positions in the preset track will correspond to different telescopic positions in the mounting housing 10 and the lens barrel assembly 20. The guide groove 31 and the guide column 32 in the guide assembly 30 can cooperate to guide the sliding track between the mounting housing 10 and the lens barrel assembly 20. When the guide groove 31 is filled with anti-collision liquid, the part of the guide column 32 extending into the guide groove 31 can be in a semi-suspended state. Under the action of the anti-collision liquid, the direct friction between the guide column 32 and the guide groove 31 can be reduced, thereby reducing the fatigue wear with the guide groove 31. And when the camera module falls and is hit, the damage of the guide column 32 can be reduced under the action of the anti-collision liquid, thereby improving the safety of the camera module. The embodiments of the present application have the beneficial effects of reducing fatigue wear of the camera module during the extension and retraction process and reducing impact damage.

[0060] It should be noted that the electronic device of the present application may be a mobile phone, a camera, a tablet computer, a laptop computer, a smart watch, etc., or other electronic devices that can be equipped with a camera module.
