The liquid camera module 100 and the electronic device 200 provided in the embodiment 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 disclosure may be applied to an electronic device 200. The electronic device can be a mobile phone, a tablet computer, an intelligent bracelet and the like.

In this embodiment, as shown in fig. 1 and 3, the liquid camera module includes: a mounting part 300 and an electrode coil 600. A liquid lens is disposed in the mount 300; the electrode coil 600 is arranged on the inner side wall of the mounting part 300 and is arranged around the liquid lens; the liquid lens leakage detection method comprises the steps that an electrode coil is in contact with liquid in the liquid lens under the condition that the liquid lens leaks, an electric signal generated by the electrode coil is larger than a first preset value, and 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 or not.

In the embodiment of the present application, when the liquid lens is in a liquid leakage state, the liquid leakage leaking from the liquid lens contacts the electrode coil 600.

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

The mounting portion 300 may have a square, rectangular, or circular shape, which is not limited in the embodiments of the present invention. The shape of the electrode coil 600 and the shape of the liquid lens may be the same as the shape of the mount 300.

It is to be understood that the liquid lens includes a liquid lens film 410, the liquid lens film 410 enclosing a liquid lens liquid 420.

In one possible implementation, as shown in fig. 2 and 3, the mount 300 shown in fig. 2 is circular, the mount 300 shown in fig. 2 and 3 is a cavity structure having an opening facing upward, 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. Therefore, 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 portion 300, and contacts the electrode coil 600.

Illustratively, the electrical signal may be a current signal or a voltage signal.

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

It can be understood that when the liquid leakage of the liquid lens contacts the electrode coil, a portion of the electrode coil is short-circuited, and thus, the electric signal of the electrode coil when the liquid lens leaks is greater than the electric signal of the electrode coil when the liquid lens does not leak.

The liquid camera module that this application embodiment provided can be through to electrode coil at the circular telegram in-process, detect electrode coil's signal of telecommunication (for example current signal or voltage signal), because when liquid camera lens weeping or when not the weeping, the signal of telecommunication of the electrode coil that corresponds is different to, whether can be greater than first default according to the signal of telecommunication that detects, whether the weeping takes place for liquid camera lens fast. Therefore, when the liquid lens leakage can be avoided, the liquid camera module and the corresponding circuit board are damaged.

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

In a first possible structure, as shown in fig. 4, 5 and 6, 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.

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

And under the condition of no liquid leakage, an open circuit is formed 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, when the liquid lens has no liquid leakage, the first coil and the second coil are not connected, and are in an open circuit state, and 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 weeping, the weeping can contact with the electrode coil to, first coil and second coil can be connected through the weeping, and then switch on between first coil and the second coil, and then the signal of telecommunication of the electrode coil that corresponds is greater than 0, and the signal of telecommunication is greater than first default promptly.

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

Illustratively, the first coil 610 may be disposed in parallel with the second coil 620, for example, in the direction of the optical axis of the liquid lens, with one coil being located above the other coil (e.g., the first coil 610 is located above the second coil 620), or with one coil being located within the other coil (i.e., one coil having an outer diameter larger than the other coil, or one coil being disposed around the other coil).

In a second possible structure, as shown in fig. 7 and 8, the electrode coil includes: 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.

And under the condition of liquid leakage, the electric signal of the electrode coil is greater 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 is understood that in the case of a leakage, there is a short circuit between the third coil and the fourth coil; and under the condition of no liquid leakage, the third coil and the fourth coil are conducted.

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

It is understood that, in this configuration, when the third coil and the fourth coil are determined, the first preset value generally fluctuates within a slight range (for example, the first preset value may be a fixed value) and is larger than 0 in the case where the power supply source is determined.

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 short-circuited, and therefore, in this case, an electrical signal (e.g., a current signal) of the corresponding electrode coil is greater 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 of the coils 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 third coil and the fourth coil have different outer diameters.

Note that, the first gap and the second gap both satisfy the following condition: when the liquid lens leaks, the first coil and the first coil can be connected through the liquid lens quickly.

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

It is understood 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 positive and negative electrodes of the power supply unit. Two electrical connection terminals 640 may be embedded within the piston ring 320 and lead out through the housing 310.

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

Optionally, in this embodiment of the application, referring to fig. 3, as shown in fig. 6, a capillary hole 630 is disposed on a side of the electrode coil 600 close to the liquid lens.

For example, the capillary hole 630 may be disposed in the first coil 610 and the second coil 620, on the coil near the liquid lens, and on the coil near the liquid lens, or the capillary hole 630 may be disposed in each of the two coils.

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

Optionally, the number of the capillary holes is multiple, and the multiple capillary holes 630 are uniformly distributed along a circumference of the electrode coil 600.

It can be understood 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 a circumference of the electrode coil 600.

The capillary holes in the embodiment of the application can play a role in adsorbing leaked liquid between the electrode coils, and the principle of the capillary phenomenon is utilized (a capillary tube is often used for explaining the capillary phenomenon, when the bottom of a thin glass tube is vertically placed in liquid (such as water), the periphery of the liquid level is slightly higher than the center of the liquid level due to the adhesive force of the tube wall of the thin glass tube to the water, and the liquid cannot stop rising continuously until the cohesive force of the liquid cannot overcome the weight of the liquid.

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

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

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

Illustratively, a detection unit is connected to a 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 can be understood that, taking an electrical signal as an example of current, the impedance of the circuit corresponding to the electrode coil also includes the impedance of the electrode coil itself, when there is no leakage or leakage on the electrode coil, the current value passing through the electrode coil inevitably has a great difference, the volume of the leakage also causes a difference, but the difference is much smaller than that when there is no leakage. The threshold value (i.e., the first preset value) may be obtained through experimental verification in advance. If the value is equal to the threshold value, no leakage can be considered, and if the value is larger than the threshold value, leakage is judged. Thus, whether leakage occurs or not can be detected.

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

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

When a voltage U is applied to the electrode coil:

when the liquid lens has no liquid leakage, the current I1 detected by the current sensor is U/(R + R1);

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

Since R1 is greater than R2, I1 will also be less than I2. Therefore, a current value between I1 and I2 may be selected as the threshold value (i.e., the first preset value), or I1 may be used as the first preset value, by 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 has no liquid leakage, and if the detected current is greater than the first preset value, it indicates that the liquid lens has liquid leakage. Therefore, whether the liquid lens leaks or not can be conveniently determined.

When the electrode coil is the electrode coil in the first possible configuration, that is, the electrode coil includes the first coil and the second coil, and when the liquid lens has no liquid leakage because the first coil and the second coil are open-circuited in the case of no liquid leakage, the impedance R1 corresponding to the electrode coil is infinite. When the electrode coil is the electrode coil in the second possible structure manner, that is, the electrode coil includes the third coil and the fourth coil, and the liquid lens has no liquid leakage, the impedance R1 corresponding to the electrode coil is the impedance corresponding to the third coil and the fourth coil.

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

In the embodiment of the present application, the liquid lens and the piston ring 320 may be hermetically connected.

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

Optionally, in the embodiment of the present application, the piston ring 320 has a groove 330 on the inner side wall, 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 close to the liquid lens, meaning: the groove is arranged around the liquid lens and is close to the liquid lens.

Wherein, the recess is close to liquid camera lens setting, indicates: 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 groove 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 "the groove is disposed near the first side of the liquid lens", the groove is disposed near the first side of the liquid lens, and means: the groove is arranged close to 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, 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, and is not repeated here for avoiding repetition.

It can be understood that the groove also has limiting effect on the electrode coil 600, can prevent the electrode coil 600 from deviating, and can prevent the electrode coil 600 from sheltering from the incident light of the liquid lens to the influence that the weeping detection result caused, thereby ensuring the shooting effect of the embodiment of the application. In addition, when the weeping takes place, this recess 330 can also play the collection effect to the weeping, prevents that the weeping from flowing at will in the camera module, avoids the weeping to cause the damage to other structures of camera module.

As shown in fig. 3, the liquid lens is disposed in the middle of the piston ring 320, the groove 330 is near 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 rapidly flow to the electrode coil 600 along the liquid lens film 410, and therefore, when the liquid lens leaks, the liquid lens can be detected in real time when the electrode coil 600 is powered on.

Optionally, in this embodiment of the 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 at the first side; the groove comprises a notch and a groove bottom; along the first direction, second side, tank bottom, first side and notch distribute in proper order.

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

Exemplarily, the electrode coil is located at a first side of the liquid lens, and means: the electrode coil is close to the first side of the liquid lens, for example, the electrode coil is disposed 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, the leaked liquid in the liquid lens contacts with the electrode coil.

It can be understood that when the first side of the liquid lens faces 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 leaking liquid can flow to the groove under the action of gravity, and the groove can collect the leaking liquid automatically. In addition, because the level of notch is higher than first side to, in to liquid camera module focusing process, can avoid the notch to lead to the fact wearing and tearing to liquid lens membrane.

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-to-top direction, and the second side, the first side, the groove bottom and the notch are sequentially arranged 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 structures of camera module.

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

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

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

In the 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 can be understood that when the liquid lens film 410 is about to be damaged, the liquid lens is in an undeformed state (i.e. an initial state), and the liquid lens does not leak, however, when the liquid lens is driven to deform by the driving unit, the liquid lens film 410 is damaged, and then the liquid leakage occurs.

Therefore, when the liquid lens is in an undeformed state, the electric signal of the electrode coil 600 is detected by electrifying the electrode coil 600, and whether the liquid lens leaks or not can be determined. Or when the liquid lens is deformed, the electric signal of the electrode coil 600 is detected by electrifying the electrode coil 600, and then whether the liquid lens leaks or not is determined.

Optionally, in the 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 piece is in the first power-on state, the electromagnetic piece attracts the magnetic piece, and in the attracting process, the magnetic piece is close to the electromagnetic piece and extrudes the liquid lens, so that the driving unit drives the liquid lens to deform.

When the electromagnetic piece is in a second electrifying state, the magnetic piece is far away from the electromagnetic piece, so that the driving unit drives the liquid lens to return to an initial state. For example, when the electromagnetic element is in the second energized state, the electromagnetic element repels the magnetic element, and during the repulsion process, the magnetic element is far away from the electromagnetic element, so that the driving unit drives the liquid lens to return to the initial state.

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

Illustratively, the magnetic member may be a magnet and the electromagnetic member may be an electrode driving coil.

It can be understood that when the liquid lens is not deformed, a first distance exists between the magnetic element and the electromagnetic element.

In one example, the energizing current of the electromagnetic member in the first energizing state may be in a direction opposite to the energizing current of the electromagnetic member in the second energizing state. Therefore, in the first power-on state, the electromagnetic piece attracts the magnetic piece, and the attraction force when attracting the magnetic piece enables the driving unit to drive the liquid lens to deform.

In another example, in the first energization state, the energization current of the electromagnetic member is greater than zero, and in the second energization state, the energization current of the electromagnetic member is zero. Therefore, in the first power-on state, the electromagnetic piece attracts the magnetic piece, and the attraction force generated when the magnetic piece is attracted enables the driving unit to drive the liquid lens to deform. It can be understood that the liquid lens film has elastic deformation performance, and has elastic restoring force when deformed, so that the liquid lens can be restored to the initial state under the action of the elastic restoring force.

It should be understood that the liquid lens returns to the initial state, which means: the liquid lens returns to the non-deformed state.

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