DETAILED DESCRIPTION

[0041] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0042] like Figures 1 to 8 As shown, the present application provides a camera module 1, comprising:

[0043] Lens assembly 10;

[0044] An image sensor device 11, wherein the image sensor device 11 is disposed on one side of the lens assembly 10 to receive light passing through the lens assembly 10;

[0045] The image sensor device 11 has a receiving space;

[0046] An adjusting member 12, disposed in the accommodation space, for adjusting the distance between a first side and a second side of the image sensor device 11, wherein the first side and the second side are disposed opposite to each other;

[0047] The adjusting member 12 has a first state and a second state different from the first state under a preset condition.

[0048] A camera module 1 provided in an embodiment of the present application includes a lens assembly 10, an image sensor device 11 and an adjustment member 12. The image sensor device 11 has a first side and a second side, the lens assembly 10 is arranged on the first side of the image sensor device 11, and the second side of the image sensor device 11 is arranged opposite to the first side and is located on a side away from the lens assembly 10. The lens assembly 10 is used to receive light from the outside and transmit the light to the image sensor device 11, and the image sensor device 11 receives the light and performs photosensitivity processing on the light to achieve imaging. The image sensor device 11 has a accommodating space, and an adjustment member 12 is arranged in the accommodating space, and the adjustment member 12 is used to adjust the distance between the first side and the second side of the image sensor device 11. Under different preset conditions, the adjusting member 12 has at least a first state or a second state different from the first state. The adjusting member 12 has different distances between the first side and the second side of the image sensor device 11 in the first state and the second state, that is, the distance between the lens assembly 10 and the image sensor device 11 is different under different states of the adjusting member 12, thereby achieving adjustment of the distance between the lens assembly 10 and the image sensor device 11 and focusing of the light to achieve focusing for better imaging.

[0049] Therefore, the camera module 1 provided by the present application can realize automatic focusing by setting an adjustment member 12 that can adjust the distance between the first side and the second side of the image sensor device 11, thereby improving the shooting quality and solving the problem of insufficient depth of field caused by the difference in hand lengths of different people. And it is not necessary to set the motor in the related design to achieve focusing, which reduces the setting of the motor, thereby reducing the height of the camera module 1, reducing the size of the camera module 1, and further realizing the lightness and thinness of the electronic device. There is no need to set a larger aperture as in the related art to avoid the motor from blocking the lens assembly 10, which reduces the opening aperture of the panel and increases the screen ratio.

[0050] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, the adjusting member 12 is in the first state, and there is a first distance between the first side and the second side of the image sensor device 11;

[0051] The adjusting member 12 is in the second state, and there is a second distance between the first side and the second side of the image sensor device 11 , and the second distance is greater than the first distance.

[0052] In this embodiment, the image sensor device 11 has a storage space, and the adjustment member 12 is arranged in the storage space. After the light is transmitted to the image sensor device 11 through the lens assembly 10, the adjustment member 12 can adjust the state according to the received light. When the light makes the adjustment member 12 under different preset conditions, the adjustment member 12 has different states. When a certain light passes through the lens assembly 10 and enters the image sensor device 11, it is the first preset condition. At this time, the adjustment member 12 is in the first state. At this time, the distance between the first side and the second side of the image sensor device 11 is the first distance. At this time, the distance between the image sensor device 11 and the lens assembly 10 can enable the image sensor device to achieve focus. When another light passes through the lens assembly 10 and enters the image sensor device 11, it is the first preset condition. At this time, the adjustment member 12 is in the second state. At this time, the distance between the first side and the second side of the image sensor device 11 is the second distance. At this time, the distance between the image sensor device 11 and the lens assembly 10 can enable the image sensor device 11 to achieve focus. Therefore, by switching the adjustment member 12 between the first state and the second state, the distance between the first side and the second side of the image sensor device 11 can be switched between the first distance and the second distance, and the first distance is smaller than the second distance. The adjustment member 12 has adaptability, fast response and high precision, so that automatic focus can be automatically achieved according to the change of the distance between the first side and the second side of the image sensor device 11, thereby improving the shooting quality.

[0053] like Figures 1 to 8 As shown, in the embodiment of the present application, the adjusting member 12 includes a liquid metal layer, a first electrode layer 122 and a second electrode layer 123 connected to two sides of the liquid metal layer;

[0054] Under the first preset condition, a positive voltage is applied to the first electrode layer 122 and the second electrode layer 123, and the liquid metal layer is in the first state;

[0055] Under the second preset condition, a negative voltage is applied to the first electrode layer 122 and the second electrode layer 123 , and the liquid metal layer is in the second state.

[0056] In this embodiment, the adjusting member 12 includes a liquid metal layer, a first electrode layer 122 and a second electrode layer 123. The first electrode layer 122 and the second electrode layer 123 are respectively arranged on both sides of the liquid metal layer and are both connected to the liquid metal layer. The first electrode layer 122 and the second electrode layer 123 are both used to apply voltage to the liquid metal layer. When a certain light passes through the lens assembly 10 and enters the image sensor device 11, it is a first preset condition. At this time, the first electrode layer 122 and the second electrode layer 123 apply a positive voltage to the liquid metal layer, and the liquid metal layer is in a first state. The distance between the first side and the second side of the image sensor device 11 is a first distance. At this time, the distance between the image sensor device 11 and the lens assembly 10 can enable the image sensor device to achieve focus. When another light passes through the lens assembly 10 and enters the image sensor device 11, the first electrode layer 122 and the second electrode layer 123 apply a negative voltage to the liquid metal layer, which is the second preset condition. The liquid metal layer is in the second state. At this time, the distance between the first side and the second side of the image sensor device 11 is the second distance. At this time, the distance between the image sensor device 11 and the lens assembly 10 can enable the image sensor device to achieve focus. Therefore, by switching the liquid metal layer between the first state and the second state, the distance between the first side and the second side of the image sensor device can be switched between the first distance and the second distance, so as to achieve automatic focus and improve the shooting quality.

[0057] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the liquid metal layer includes at least one liquid metal body 121;

[0058] In the first state, the liquid metal body 121 is a flat structure;

[0059] In the second state, the liquid metal body 121 is a spherical structure.

[0060] In this embodiment, the storage space of the image sensor device 11 contains liquid metal, and the liquid metal includes at least one liquid metal body 121. The first electrode layer 122 and the second electrode layer 123 are connected to the two sides of the at least one liquid metal body 121 respectively. Under the first preset condition, the first electrode layer 122 and the second electrode layer 123 apply a positive voltage to the at least one liquid metal body 121, and the at least one liquid metal body 121 to which the positive voltage is applied is in a first state and presents a flat shape. At this time, there is a first distance between the first side and the second side of the image sensor device 11 having the liquid metal body 121. Under the second preset adjustment, the first electrode layer 122 and the second electrode layer 123 apply a negative voltage to the at least one liquid metal body 121, and the at least one liquid metal body 121 to which the negative voltage is applied is in a second state and presents a spherical structure. At this time, there is a second distance between the first side and the second side of the image sensor device 11 having the liquid metal body 121. The thickness of the flat structure is smaller than that of the spherical structure, so that the first distance is smaller than the second distance, so that the first electrode layer 122 and the second electrode layer 123 can be controlled to apply different voltages to the liquid metal body 121 according to different situations, so as to achieve the change of different states of the liquid metal body 121, so as to change the distance between the first side and the second side of the image sensor device 11 through the change of different states of the liquid metal body 121, so as to achieve automatic focusing. The arrangement of the liquid metal body 121 as a flat structure or a spherical structure reduces the contact area with the electrode layer, thereby reducing the risk of short circuit.

[0061] In this embodiment, the adjusting member may also be a strip-shaped structure, and may have different thicknesses along the direction from the first side to the second side of the image sensor device according to different voltages.

[0062] like Figures 1 to 3 As shown, in the embodiment of the present application, at least one liquid metal body 121 is connected between the first electrode layer 122 and the second electrode layer 123, so that the liquid metal bodies 121 are in the same state; or

[0063] The first electrode layer 122 has at least one first electrode body 1221 , and the second electrode layer 123 has at least one second electrode body 1231 ;

[0064] The first electrode body 1221 , the second electrode body 1231 and the liquid metal body 121 are arranged correspondingly; the liquid metal body 121 is connected to the first electrode body 1221 and the second electrode body 1231 .

[0065] In this embodiment, one or more liquid metal bodies 121 may be provided between the first electrode layer 122 and the second electrode layer 123, and each liquid metal body 121 is connected to the first electrode layer 122 and the second electrode layer 123, so that when a positive voltage is applied to the first electrode layer 122 and the second electrode layer 123, one or more liquid metal bodies 121 at different positions are simultaneously in a flat structure, and when a negative voltage is applied to the first electrode layer 122 and the second electrode layer 123, one or more liquid metal bodies 121 at different positions are simultaneously in a spherical structure, so that the same first electrode layer 122 and the second electrode layer 123 can simultaneously synchronously control the state of one or more liquid metal bodies 121, so as to better achieve the adjustment of the distance between the first side and the second side of the image sensor device 11. In addition, different liquid metal bodies 121 can also adjust their shapes by individually controlling the voltage of the corresponding electrode layer to achieve the purpose of compensating the inclination of the sensor.

[0066] In this embodiment, the first electrode layer 122 has one first electrode body 1221 or multiple first electrode bodies 1221, the second electrode layer 123 has one second electrode body 1231 or multiple second electrode bodies 1231, each first electrode body 1221, each liquid metal body 121 and each second electrode body 1231 are arranged opposite to each other, and each liquid metal body 121 is connected to the first electrode body 1221 and the second electrode body 1231 arranged opposite to each other, so that the state of the liquid metal body 121 can be controlled according to the voltage applied by the first electrode body 1221 and the second electrode body 1231 arranged opposite to each other, so that the liquid metal body 121 at different positions can achieve different states according to the different voltages applied by the corresponding first electrode body 1221 and the second electrode body 1231. Therefore, the first side or the second side of the image sensor device 11 can be tilted, or the purpose of compensating the tilt of the sensor can be achieved, so that more focusing methods can be provided to take better quality photos.

[0067] In this embodiment, the liquid metal body 121 is a gallium-based liquid metal, which has some characteristics of both liquid and solid, including high electrical conductivity / high thermal conductivity, good flexibility, extremely low toxicity and non-volatile. Gallium-based liquid metal is easily oxidized to form a surface oxide film. When not oxidized, the liquid metal body 121 has the largest surface tension among currently known liquids (>600mN / m). After oxidation, the surface tension of the liquid metal body 121 can be reduced to nearly 0. The first electrode layer 122 and the second electrode layer 123 can be copper electrodes, which not only provide oxidation / reduction voltage for the liquid metal body 121, but the excellent wettability of copper and liquid metal also enables the liquid metal body 121 to be anchored on the copper sheet. The liquid metal body 121 forms a liquid bridge between the upper and lower copper electrodes. When the electrode provides a positive oxidation voltage, the liquid metal body 121 changes from a nearly spherical shape to a flat mud shape, and the force of the liquid bridge on the upper substrate is downward, the height of the liquid bridge decreases, and a downward contraction movement is achieved; when the electrode provides a negative reduction voltage, the liquid metal body 121 recovers from a flat mud shape to a nearly spherical shape, and the force of the liquid bridge on the upper substrate is upward, the liquid bridge recovers its initial height, and an upward expansion movement is achieved.

[0068] like Figure 3 As shown, in the embodiment of the present application, an insulating spacer layer 18 is provided between two adjacent liquid metal bodies 121 , and two ends of the insulating spacer layer 18 along the thickness direction are respectively connected to the first electrode layer 122 and the second electrode layer 123 .

[0069] In this embodiment, one or more liquid metal bodies 121 may be provided between the first electrode layer 122 and the second electrode layer 123. When there are multiple liquid metal bodies between the first electrode layer 122 and the second electrode layer 123, an insulating spacer layer 18 is provided between two adjacent liquid metal bodies 121. The two ends of the insulating spacer layer 18 are respectively connected to the first electrode layer 122 and the second electrode layer 123. The insulating spacer layer 18 is used to insulate and space the two adjacent liquid metal bodies 121 to prevent the two adjacent liquid metal bodies 121 from touching each other and causing a short circuit. The insulating spacer layer 18 has a certain elasticity and may be made of rubber or other materials, so that when the state of the liquid metal body 121 changes, it can be driven by the connected first electrode layer 122 and the second electrode layer 123 to extend or compress, thereby changing the state synchronously with the multiple liquid metal bodies 121 whose states change, so as not to affect the change in the distance between the first side and the second side of the image sensor device 11. The insulating spacer layer 18 may be an insulating film or coating, or an isolation structure made of insulating material.

[0070] In the embodiment of the present application, the regulating member 12 includes a memory alloy layer and a temperature controller connected to the memory alloy layer, and the temperature controller is used to regulate and control the temperature of the memory alloy layer;

[0071] Under a first preset condition, the temperature controller controls the temperature of the memory alloy layer to be in a first temperature range, and the memory alloy layer is in a first state;

[0072] Under the second preset condition, the temperature controller controls the temperature of the memory alloy layer to be in a second temperature range, and the memory alloy layer is in a second state.

[0073] In this embodiment, the adjustment member 12 provided in the accommodation space of the image sensor device 11 may also be a memory alloy layer, and the memory alloy layer is connected to a temperature controller, so that the temperature controller can adjust the state of the memory alloy layer according to a preset condition, so that the memory alloy layer switches between a first state and a second state. When a certain light passes through the lens assembly 10 and enters the image sensor device 11, it is a first preset condition, at which time the temperature controller controls the temperature of the memory alloy layer to be in a first temperature range, and the memory alloy layer is in a first state. The memory alloy layer in the first state has a first thickness in the direction from the first side to the second side of the image sensor device 11, and at this time the distance between the first side and the second side of the image sensor device 11 is a first distance, and the distance between the image sensor device 11 and the lens assembly 10 can enable the image sensor device to achieve focusing. When another light passes through the lens assembly 10 and enters the image sensor device 11, it is the second preset condition. At this time, the temperature controller controls the temperature of the memory alloy layer to be in the second temperature range, and the memory alloy layer is in the second state. The memory alloy layer in the second state has a second thickness in the direction from the first side to the second side of the image sensor device 11, and the second thickness is greater than the first thickness. At this time, the distance between the first side and the second side of the image sensor device 11 is the second distance, and the distance between the image sensor device 11 and the lens assembly 10 can enable the influence sensor device to achieve focus. Therefore, by switching the memory alloy layer between the first state and the second state, the distance between the first side and the second side of the influence sensor device can be switched between the first distance and the second distance, so as to achieve automatic focus and improve the shooting quality.

[0074] In this embodiment, the camera module 1 also has a feedback control system, which monitors the clarity of the image in real time through image processing algorithms and sensors, and controls the voltage of the first electrode layer 122 and the second electrode layer 123 or the temperature control signal of the temperature controller accordingly, thereby adjusting the state of the adjustment member 12 to achieve automatic focusing. The adjustment member 12 can also have a variety of different states, and the feedback control system controls the voltage of the first electrode layer 122 and the second electrode layer 123 or the temperature control signal of the temperature controller to be multiple, and the adjustment member 12 can have a variety of different states between the first state and the second state, so as to better achieve the focusing effect.

[0075] like Figures 4 to 8As shown, in an embodiment of the present application, the image sensing device 11 also includes a microlens 13, a filter 14, a photodiode layer 15 and a metal wire layer 16, and the adjustment member 12 is arranged between any two adjacent structures among the microlens 13, the filter 14, the photodiode layer 15 and the metal wire layer 16.

[0076] In this embodiment, the image sensing device 11 includes a microlens 13, a filter 14, a photodiode layer 15 and a metal wire layer 16. The adjusting member 12 can be arranged between the microlens 13 and the filter 14, between the filter 14 and the photodiode layer 15, or between the photodiode layer 15 and the metal wire layer 16, so that the position of the adjusting member 12 can be set at different positions according to needs.

[0077] like Figures 1 to 3 As shown, in the embodiment of the present application, an elastic filling layer 17 is provided on the peripheral side of the adjusting member 12 , and the elastic filling layer 17 can adapt to the first state or the second state of the adjusting member 12 .

[0078] In this embodiment, an elastic filling layer 17 is further provided on the peripheral side of the adjusting member 12, and the two sides of the elastic filling layer 17 are respectively connected to the structures on the two sides of the adjusting member 12, and can be connected by pasting. When the adjusting member 12 is located between the microlens 13 and the optical filter 14, the two sides of the elastic filling layer 17 are respectively connected to the microlens 13 and the optical filter 14; when the adjusting member 12 is located between the optical filter 14 and the photodiode layer 15, the two sides of the elastic filling layer 17 are respectively connected to the optical filter 14 and the photodiode layer 15; when the adjusting member 12 is located between the photodiode layer 15 and the metal wire layer 16, the two sides of the elastic filling layer 17 are respectively connected to the photodiode layer 15 and the metal wire layer 16; thus, the elastic filling layer 17 encloses and protects the adjusting member 12 to prevent the adjusting member 12 from falling off or being damaged. The elastic filling layer 17 is supported by elastically deformable materials such as rubber, so that it can change its shape simultaneously according to the state change of the adjusting member 12 to adapt to the first state or the second state of the adjusting member 12, avoiding affecting the change of the distance between the first side and the second side of the image sensor device 11.

The adjusting member 12 has different distances between the first side and the second side of the image sensor device 11 in the first state and the second state, that is, the distance between the lens assembly 10 and the image sensor device 11 is different under different states of the adjusting member 12, thereby realizing the movement of the image sensor device 11 to achieve focusing, so that shooting and recording are no longer blurred, with better imaging, so that live broadcasting is more convenient.

[0086] Thus, the electronic device provided by the present application can adjust the distance between the first side and the second side of the image sensor device 11 in the camera module 1 through the setting of the adjustment member 12 integrally set in the camera module 1, so as to achieve automatic focus, thereby improving the shooting quality and solving the problem of insufficient depth of field caused by the difference in hand lengths of different people. And it is not necessary to set the motor in the related design to achieve focusing, which reduces the setting of the motor, thereby reducing the height of the camera module 1, reducing the size of the camera module 1, and further realizing the lightness and thinness of the electronic device. There is no need to set a larger aperture as in the related art to avoid the motor from blocking the lens assembly 10, which reduces the size of the camera module 1 on the electronic device panel and increases the screen ratio.

[0087] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
