The liquid camera module 100 and the electronic device 200 provided in the embodiments of the present application are described below with reference to fig. 1 to 7.

As shown in fig. 1, a liquid camera module 100 according to an embodiment of the present application may be applied to an electronic device 200. The electronic device can be a mobile phone, a tablet personal computer, a smart bracelet and the like.

In this embodiment, as shown in fig. 1 and fig. 3, the above liquid camera module includes: a mounting portion 300 and an electrode coil 600. The mounting portion 300 is provided with a liquid lens therein; the electrode coil 600 is disposed on the inner sidewall of the mounting part 300, and the electrode coil is disposed around the liquid lens; under the condition that liquid lens leaks, the electrode coil is in contact with liquid in the liquid lens, and an electric signal generated by the electrode coil is larger than a first preset value, wherein the first preset value is an electric signal value generated by the electrode coil under the condition that the liquid lens does not leak. The electric signal of the electrode coil can be detected to determine whether the liquid lens leaks.

In this embodiment, when the liquid lens is in a liquid leakage state, the leaked liquid leaked from the liquid lens contacts the electrode coil 600.

In this embodiment, the mounting portion 300 may be a cavity structure with an opening, and the liquid lens may be disposed in the cavity, and may be disposed in the middle of the cavity, or near the opening of the cavity.

It should be noted that the mounting portion 300 may have a square, rectangular, or circular shape, which is not limited in the embodiment of the present application. The shape of the electrode coil 600 and the shape of the liquid lens may be the same as the shape of the mounting part 300.

It is understood that the liquid lens includes a liquid lens film 410, and the liquid lens film 410 is wrapped with a liquid lens liquid 420.

In a possible implementation manner, as shown in fig. 2 and 3, the shape of the mounting portion 300 shown in fig. 2 is a circle, the mounting portion 300 shown in fig. 2 and 3 is a cavity structure with one opening facing upwards, the liquid lens is disposed in the middle of the cavity, and the electrode coil 600 is disposed near the upper surface of the liquid lens. Accordingly, when the liquid lens is in a liquid leakage state, the liquid leakage of the liquid lens flows along the liquid lens film 410 to the inner sidewall of the mounting part 300 to contact the electrode coil 600.

The electrical signal may be a current signal or a voltage signal, for example.

It can be understood that, under the condition that the electrode coil is electrified, when the liquid lens leaks or does not leak, the electric signals of the corresponding electrode coil are different, so that when the liquid lens does not leak, that is, when the liquid lens is completely undamaged, the electric signals under the condition that the electrode coil is electrified can be collected in advance, and the collected electric signals are stored in the storage unit as a first preset value.

It will be appreciated that when the liquid lens leaks into contact with the electrode coil, a portion of the electrode coil is shorted, and therefore the electrical signal of the electrode coil when the liquid lens leaks is greater than the electrical signal of the electrode coil when the liquid lens does not leak.

According to the liquid camera module provided by the embodiment of the application, the electric signals (such as current signals or voltage signals) of the electrode coils can be detected in the electrifying process of the electrode coils, and the corresponding electric signals of the electrode coils are different when the liquid lens leaks or does not leak liquid, so that whether the liquid lens leaks or not can be rapidly determined according to whether the detected electric signals are larger than the first preset value. Therefore, when the liquid lens leaks, the damage to the liquid camera module and the corresponding circuit board can be avoided.

Alternatively, in the embodiment of the present application, the electrode coil 600 includes, but is not limited to, the following two possible structural manners.

A first possible construction is shown in fig. 4, 5 and 6, wherein the electrode coil 600 includes a first coil 610 and a second coil 620; a first gap exists between the first coil 610 and the second coil 620.

Under the condition of liquid leakage, the first coil and the second coil are conducted, and the electric signal of the electrode coil is larger than a first preset value.

And under the condition of no leakage, an open circuit exists between the first coil and the second coil, and the electric signal of the electrode coil is equal to a first preset value.

Illustratively, the first preset value may be 0.

It can be understood that, since the first gap exists between the second coil and the first coil, in the case that the liquid lens is not leaked, the first coil and the second coil are not connected, and in an open state, an electrical signal (e.g., a current signal) of the corresponding electrode coil is 0, that is, the electrical signal is equal to the first preset value. Under the condition of liquid lens leakage, the leakage can be in contact with the electrode coil, so that the first coil and the second coil can be connected through the leakage, and then the first coil and the second coil are conducted, and the electric signal of the corresponding electrode coil is larger than 0, namely the electric signal is larger than a first preset value.

Illustratively, the electrode coil 600 includes two coils (i.e., a first coil 610 and a second coil 620).

For example, the first coil 610 may be disposed in parallel with the second coil 620, e.g., in the direction of the optical axis of the liquid lens, with one coil above the other (e.g., the first coil 610 above the second coil 620), or with one coil inside the other (i.e., with one coil having an outer diameter greater than the outer diameter of the other coil, or with one coil disposed around the other coil).

A second possible construction, as shown in fig. 7 and 8, the electrode coil comprises: a third coil and a fourth coil; the third coil and the fourth coil form a spiral structure, the third coil is electrically connected with the fourth coil, and a second gap exists between the third coil and the fourth coil in the optical axis direction of the liquid lens.

Under the condition of liquid leakage, the electric signal of the electrode coil is larger than a first preset value.

In the case of no leakage, the electrical signal of the electrode coil is equal to a first preset value.

It will be appreciated that in the event of a liquid leak, there is a short circuit between the third coil and the fourth coil; and under the condition of no leakage, the third coil and the fourth coil are conducted.

Illustratively, the first preset value may be: and when the liquid lens is not leaked, an electric signal is generated between the third coil and the fourth coil.

It will be appreciated that in this structural approach, when the third coil and the fourth coil are determined, the first preset value generally fluctuates in a small range (for example, the first preset value may be a fixed value) in the case where the power supply is determined, and the first preset value is greater than 0.

When the liquid lens leaks, the third coil and the fourth coil are communicated through the leakage, so that the third coil and the fourth coil are in short circuit, and therefore, in the case, the electric signal (such as a current signal) of the corresponding electrode coil is larger than a first preset value.

Illustratively, the electrode coil includes two coils (i.e., a third coil and a fourth coil).

For example, one end of the third coil may be connected to one end of the fourth coil to form a spiral structure, and one coil is located above the other coil (e.g., the third coil is located above the fourth coil) in the optical axis direction of the liquid lens. In this case, the outer diameters of the two coils may be the same or different in the third coil and the fourth coil.

Illustratively, the third coil and the fourth coil are at the same level, in which case the outer diameters of the third coil and the fourth coil are different.

The first gap and the second gap satisfy the following conditions: when the liquid lens leaks, the first coil and the first coil can be connected with each other through the liquid lens.

Thus, the electric signal (current signal or voltage signal) of the electrode coil can be detected during energization of the electrode coil. When the liquid lens leaks, the first gap (or the second gap) is filled with the liquid, so that the first coil and the first coil (or the third coil and the fourth coil) are connected through the filled liquid, and conduction (or short circuit between the third coil and the fourth coil) is caused between the first coil and the second coil, and therefore, when the liquid lens leaks or does not leak, the electric signals of the corresponding electrode coils are different. Therefore, whether the liquid lens leaks or not can be rapidly determined according to the detected electric signals.

It will be appreciated that as shown in fig. 5 and 6, the first coil 610 and the second coil 620 (or the third coil and the fourth coil) respectively correspond to one electrical connection terminal 640, and the two electrical connection terminals 640 are respectively used for connecting the positive and negative poles of the power supply unit. Two electrical connections 640 may be embedded in the piston ring 320 and led out through the housing 310.

It should be noted that, the number of coils included in the electrode coil is N, N is a positive integer, if N is 1, the corresponding coil has the characteristic of larger impedance, and generally, N is 2, so as to meet the requirement of detecting whether the liquid lens leaks. Of course, N may be greater than 2, and gaps exist between each coil, so that it may be determined whether the liquid lens leaks by detecting whether the short circuit condition exists between each gap.

Optionally, in an embodiment of the present application, as shown in fig. 3 and fig. 6, a capillary hole 630 is disposed on a side of the electrode coil 600 near the liquid lens.

Illustratively, the capillary holes 630 may be disposed on the coil near the liquid lens in the first coil 610 and the second coil 620, and disposed on the side of the coil near the liquid lens, or the capillary holes 630 may be disposed in the two coils, respectively.

Similarly, the capillary holes 630 may be also disposed in the third coil and the fourth coil, and the specific manner of disposition may refer to the first coil 610 and the second coil 620, which are not described herein again.

Alternatively, the number of capillary holes is plural, and the plurality of capillary holes 630 are uniformly distributed along the circumference of the electrode coil 600.

It will be appreciated that if a plurality of capillary holes 630 are provided on each coil, the plurality of capillary holes 630 of each coil are uniformly distributed along the circumference of the electrode coil 600.

The capillary holes in the embodiments of the present application can play a role of absorbing leakage liquid to the electrode coil, and utilize the principle of capillary phenomenon (capillary is often used as an illustration of capillary phenomenon, when the bottom of a thin glass tube is vertically placed in liquid (such as water), the adhesion force of the wall of the thin glass tube to water can make the periphery of the liquid level slightly higher than the center, and the liquid can not stop rising until the cohesive force of the liquid can not overcome the weight of the liquid.

Therefore, when a small amount of liquid leakage occurs in the liquid lens according to the embodiment of the present application, the liquid leakage can be easily absorbed between the electrode coils 600, for example, between the first coil 610 and the second coil 620, by using the capillary phenomenon principle under the absorption action of the capillary holes 630 on the electrode coils 600, so that the first coil 610 and the second coil 620 are connected through the liquid leakage, and thus, the electric signal of the electrode coils 600 is conveniently detected to change. That is, when a small amount of liquid leakage occurs in the liquid lens, the liquid leakage of the liquid lens can be detected in real time.

Optionally, in this embodiment of the present application, the impedance value on the circuit corresponding to the electrode coil 600 is greater than or equal to a second preset value.

It can be understood that in order to avoid the influence caused by the short circuit of the electrode coil when the liquid lens leaks, the impedance value on the circuit corresponding to the electrode coil is greater than or equal to the second preset value, so that the safety of the corresponding circuit is ensured when the electrode coil is in short circuit, and the damage to other components caused by the short circuit is prevented.

Illustratively, a detection unit is connected to the circuit corresponding to the electrode coil, the detection unit is configured to detect the electrical signal, and the impedance value of the circuit corresponding to the electrode coil includes an impedance value of the detection unit (e.g., a fixed impedance of the detection unit).

It will be appreciated that, taking the electrical signal as the current, the impedance of the circuit corresponding to the electrode coil also includes the impedance of the electrode coil itself, and when there is no leakage and no leakage on the electrode coil, the current value passing through the electrode coil must have a large difference, and the volume of the leakage will also cause a difference, but the difference will be much smaller than that without the leakage. The threshold value (i.e., the first preset value described above) may be obtained through experimental verification in advance. A threshold value is considered to be no leakage, and if the threshold value is larger than the threshold value, the leakage is judged. Thus, it is possible to detect whether or not a leakage has occurred.

It should be noted that the threshold value may be stored in the storage unit of the liquid camera module.

In an example, taking a detection unit as an example of a current sensor, the current sensor may be used to detect a current signal (i.e. the electrical signal) of an electrode coil, if a fixed impedance of the current sensor is R, when the liquid lens is not leaked, an impedance corresponding to the electrode coil is R1, and when the liquid lens is leaked, an impedance corresponding to the electrode coil is R2.

When a voltage U is applied to the electrode coil:

when the liquid lens is not leaked, the current I1 = U/(R+R1) detected by the current sensor;

When the liquid lens leaks, the current I2=U/(R+R2) detected by the current sensor.

Since R1 is greater than R2, I1 will also be less than I2. Therefore, a current value may be selected between I1 and I2 as the threshold value (i.e., the first preset value), or I1 may be used as the first preset value, and comparing the current detected by the current sensor with the first preset value, if the detected current is equal to the first preset value, it indicates that the liquid lens is not leaked, and if the detected current is greater than the first preset value, it indicates that the liquid lens is leaked. Therefore, whether the liquid lens leaks or not can be conveniently determined.

It should be noted that, when the electrode coil is the electrode coil in the first possible structural manner, that is, the electrode coil includes the first coil and the second coil, since the first coil and the second coil are open-circuited in the case of no leakage, when the liquid lens is not leaked, the impedance R1 corresponding to the electrode coil is infinite. When the electrode coil is in the second possible structural mode, that is, the electrode coil includes the third coil and the fourth coil, the impedance R1 corresponding to the electrode coil is the impedance corresponding to the third coil and the fourth coil when the liquid lens is not leaked.

Alternatively, in the embodiment of the present application, as shown in fig. 3, the mounting portion 300 includes: a housing 310 and a piston ring 320; the piston ring 320 is disposed in the housing 310, and the liquid lens and the electrode coil 600 are disposed in the piston ring 320.

In this embodiment, the liquid lens and the piston ring 320 may be connected in a sealing manner.

For example, the liquid lens may be sealingly coupled to a middle portion of the piston ring 320, or near an end portion of the piston ring 320, or at an end portion of the piston ring 320. The piston ring 320 may have a rectangular, square or circular shape.

Optionally, in this embodiment, a groove 330 is formed in the inner side wall of the piston ring 320, and the electrode coil is disposed in the groove, and the groove surrounds and is close to the liquid lens.

Illustratively, the groove surrounds and is proximate to the liquid lens, meaning: the groove is arranged around the liquid lens, and the groove is arranged close to the liquid lens.

Wherein, the recess is close to the setting of liquid camera lens, means: the distance between the groove and the liquid lens meets a first condition, so that when the liquid lens leaks, leaked liquid in the liquid lens can be in contact with the electrode coil in the groove.

Further, the recess 330 may be disposed proximate to the first side of the liquid lens and/or the second side of the liquid lens. Wherein the second side is opposite to the first side.

For example, by way of illustration of "the groove is disposed proximate the first side of the liquid lens," the groove is disposed proximate the first side of the liquid lens: the groove is arranged against the first side of the liquid lens, or the distance between the groove and the first side of the liquid lens is equal to a preset distance, so that when the liquid lens leaks, the leaked liquid in the liquid lens can be in contact with the electrode coil in the groove.

The specific manner in which the groove is disposed near the second side of the liquid lens may refer to the manner in which the groove is disposed near the first side of the liquid lens, so as to avoid repetition, and will not be described herein again.

It can be understood that the groove also has a limiting effect on the electrode coil 600, can prevent the electrode coil 600 from shifting, and can also prevent the electrode coil 600 from shielding the incident light of the liquid lens, thereby ensuring the shooting effect of the embodiment of the application. In addition, when the liquid leakage occurs, the groove 330 can also collect the liquid leakage, so that the liquid leakage is prevented from flowing in the camera module at will, and damage to other structural members of the camera module caused by the liquid leakage is avoided.

As shown in fig. 3, the liquid lens is disposed in the middle of the piston ring 320, the groove 330 is close to the upper surface of the liquid lens, and the electrode coil 600 is disposed in the groove 330. Therefore, when the liquid lens leaks, the liquid lens can quickly flow to the electrode coil 600 along the liquid lens film 410, so that when the liquid lens leaks, the liquid lens can be detected to leak in real time in the process of electrifying the electrode coil 600.

Optionally, in an embodiment of the present application, the liquid lens includes a first side and a second side, and the second side is opposite to the first side; the electrode coil is positioned on the first side; the groove comprises a notch and a groove bottom; along the first direction, the second side, the groove bottom, the first side and the notch are distributed in sequence.

Wherein, the first direction is: from the second side to the first side.

Illustratively, the electrode coil being located on the first side of the liquid lens means: the electrode coil is close to the first side of the liquid lens, for example, the electrode coil is arranged against the first side of the liquid lens, or the distance between the electrode coil and the first side of the liquid lens is equal to a preset distance, so that when the liquid lens leaks, leaked liquid in the liquid lens contacts with the electrode coil.

It will be appreciated that when the first side of the liquid lens is oriented upward, the level of the bottom of the groove 330 is lower than that of the first side of the liquid lens, so that when the liquid lens leaks, the leaked liquid can flow to the groove under the action of gravity, and the groove can automatically collect the leaked liquid conveniently. In addition, the notch is higher than the first side, so that abrasion of the notch to the liquid lens film can be avoided in the focusing process of the liquid camera module.

Alternatively, the second side, the first side, the groove bottom, and the notch may be sequentially distributed along the first direction.

Illustratively, referring to fig. 3, the first direction is a bottom-up direction, and the second side, the first side, the groove bottom, and the notch are sequentially disposed from bottom to top.

So, when taking place the weeping, conveniently collect the weeping through the recess, prevent that the weeping from flowing at will in the camera module, avoid the weeping to cause the damage to other structure of camera module.

It can be understood that when the liquid lens is deformed, the middle part of the first side of the liquid lens is convex, and the notch of the groove and the middle part of the first side of the liquid lens are sequentially distributed along the first direction.

Thus, when leakage occurs, the leakage can be enabled to flow into the groove quickly.

Optionally, in an embodiment of the present application, as shown in fig. 2 and fig. 3, the above liquid camera module further includes: and the driving unit is used for driving the liquid lens to deform.

In this embodiment of the present application, the purpose of driving the liquid lens to deform is to adjust the focal length of the liquid lens.

It will be appreciated that when the liquid lens film 410 is about to break, the liquid lens is in an undeformed state (i.e., an initial state), and no liquid leakage occurs, however, when the liquid lens is driven by the driving unit to deform, the liquid lens film 410 breaks and liquid leakage occurs.

Therefore, when the liquid lens is in a state of not being deformed, the electrode coil 600 is electrified to detect the electric signal of the electrode coil 600, so that whether the liquid lens leaks or not can be determined. When the liquid lens is deformed, the electrode coil 600 is electrified to detect the electric signal of the electrode coil 600, so as to determine whether the liquid lens leaks.

Optionally, in an embodiment of the present application, a first space exists between the piston ring and the housing, and the liquid lens extends from the piston ring to the first space; the driving unit is located in the first space and comprises a magnetic piece and an electromagnetic piece.

When the electromagnetic member is in a first electrified state, the electromagnetic member attracts the magnetic member, and in the attraction process, the magnetic member is close to the electromagnetic member and extrudes the liquid lens so that the driving unit drives the liquid lens to deform.

When the electromagnetic member is in the second power-on state, the magnetic member is far away from the electromagnetic member, so that the driving unit drives the liquid lens to return to the initial state. For example, when the electromagnetic member is in the second energizing state, the electromagnetic member repels the magnetic member, and during the repulsive process, the magnetic member is far away from the electromagnetic member, so that the driving unit drives the liquid lens to return to the initial state.

For example, the magnetic element may be in contact with the liquid lens film, i.e. the magnetic element may be arranged against the liquid lens.

The magnetic element may be a magnet and the electromagnetic element may be an electrode drive coil, for example.

It will be appreciated that when the liquid lens is not deformed, a first distance exists between the magnetic member and the electromagnetic member.

In one example, the energizing current of the solenoid in the first energized state may be in an opposite direction than the energizing current of the solenoid in the second energized state. Therefore, in the first electrifying state, the electromagnetic part attracts the magnetic part, and the attraction force generated when attracting the magnetic part is used for enabling the driving unit to drive the liquid lens to deform, and in the second electrifying state, the electromagnetic part repels the magnetic part, and the repulsive force generated when repelling the magnetic part is used for enabling the driving unit to drive the liquid lens to return to the initial state.

In another example, in the first energized state, the energized current of the solenoid is greater than zero, and in the second energized state, the energized current of the solenoid is zero. Therefore, in the first electrifying state, the electromagnetic piece attracts the magnetic piece, and the attractive force generated when the magnetic piece is attracted, so that the driving unit drives the liquid lens to deform, and in the second electrifying state, the attractive force between the electromagnetic piece and the magnetic piece disappears, so that the driving unit drives the liquid lens to return to the initial state. It can be understood that the liquid lens film has elastic deformation property, and when deformation occurs, the liquid lens film has elastic restoring force, so that the liquid lens can restore to an initial state under the action of the elastic restoring force.

It can be understood that the liquid lens returning to the initial state means: the liquid lens returns to the state of no deformation.

It should be noted that, when the electromagnetic member repels the magnetic member, the electromagnetic member may be in a power-off state after the driving unit drives the liquid lens to return to the initial state.

The method comprises step 101 and step 102.

Step 101, detecting an electrode coil of the liquid camera module under the condition that a starting instruction of a liquid lens of the liquid camera module is detected, and obtaining a first electric signal.

Step 102, if the first electrical signal is greater than a first preset value, displaying a first prompt message.

It is understood that the electrical signal includes a first electrical signal.

In this embodiment of the present application, the start instruction may be: shooting instructions, such as a shooting instruction or a video instruction.

Illustratively, the electrode coil may be: the electrode coil including the first coil and the first coil may be the electrode coil including the third coil and the fourth coil, or may be the other possible electrode coil.

In this embodiment of the present application, when the above start instruction is detected, the liquid lens is in a state of not being deformed. In this case, power may be supplied to the electrode coil through the power supply unit, and thus, the first electric signal of the electrode coil may be detected through the above-described detection unit for detecting an electric signal. That is, the first electrical signal is: when the liquid lens is in a state of not deforming, the corresponding electrode coil is in an electric signal.

In this embodiment of the present application, the first preset value may be the threshold value, and the first preset value may be detected in advance and stored in the storage unit.

In the embodiment of the application, the first prompt information can be displayed in a highlighting mode, so that a user can conveniently check the first prompt information.

Illustratively, the first hint information includes at least one of: the prompt information is identified by the text prompt information. Taking text prompt information as an example, the first prompt information may be: and (5) leaking liquid from the liquid lens.

Optionally, in the embodiment of the present application, when the liquid lens deforms, a liquid leakage condition is detected, and based on this, the method further includes steps 103 to 105.

Step 103, if the first electrical signal is equal to the first preset value, the driving unit of the liquid camera module drives the liquid lens to deform.

104, detecting an electrode coil of the liquid camera module to obtain a second electric signal;

step 105, determining whether to control the liquid lens to be in a starting state according to the second voltage signal.

It will be appreciated that the electrical signals described above also include a second electrical signal.

The second electrical signal may be a second current signal or a second voltage signal, for example.

It will be appreciated that the liquid lens is not subject to leakage when deformed, however, when deformed, the liquid lens film may be damaged by compression during use, thereby leaking. In order to ensure that the liquid lens is in a state of no liquid leakage no matter deformed or not, therefore, when the liquid lens is in a deformed state, whether the liquid lens leaks or not needs to be detected.

In this embodiment of the present application, if the first electrical signal is equal to the first preset value, it is indicated that when the liquid lens is in a state where deformation does not occur, the liquid lens is not leaked. In this case, the liquid lens may be driven to deform by the driving unit.

After the liquid lens is deformed, the electrode coil can be detected through the detection unit to obtain a second electric signal, and then whether the liquid lens is controlled to be in a starting state is determined according to the second electric signal.

It is understood that the second electrical signal is: when the liquid lens is in a deformed state, the corresponding electrode coil is in an electric signal.

step 105b, if the second electrical signal is greater than the first preset value, displaying a second prompt message;

the second prompt message is used for prompting the liquid lens to leak.

It can be understood that if the second electrical signal is equal to the first preset value, which indicates that the liquid lens is not leaked, the liquid lens can be used normally, and the liquid lens can be controlled to be in a starting state.

If the second electric signal is larger than the first preset value, the liquid lens leakage is indicated, and then a second prompt message can be displayed. The specific scheme of the second prompt information may refer to the first prompt information, which is not described herein again.

Optionally, in the embodiment of the present application, the step 103 of "driving the liquid lens to deform by the driving unit of the liquid camera module" includes step 103a.

Step 103a, driving the liquid lens to generate a first deformation by the driving unit of the liquid camera module.

The first deformation amount is larger than or equal to the first preset deformation amount and smaller than the second preset deformation amount.

It should be noted that the second preset deformation amount is a deformation amount corresponding to the maximum deformation of the liquid lens, and the first preset deformation amount is a deformation amount corresponding to the minimum deformation of the liquid lens.

For example, the first deformation amount may be slightly smaller than the second preset deformation amount. Therefore, the liquid lens can be prevented from being damaged due to overlarge first deformation, and whether liquid leakage occurs during normal operation of the liquid lens can be detected.

According to the liquid camera leakage detection method, under the condition that the starting instruction of the liquid lens of the liquid camera module is detected, the electrode coil of the liquid camera module can be detected, and a first electric signal is obtained; if the first electric signal is larger than a first preset value, displaying first prompt information; the first prompt message is used for prompting liquid lens leakage.
