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

[0033] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0035] At present, electronic devices equipped with lifting camera modules usually determine whether to stop the lifting of the camera by detecting the lifting distance of the camera. In related technologies, a more mature lifting distance detection method is to bind a Hall sensor to the camera module, set a Hall sensor at the motor sliding module, and set magnets at the starting and end points of the motor slide rail. When the motor sliding module reaches the end point, the Hall sensor is triggered by the magnetic field of the magnet and the motor stops working.

[0036] However, the method of detecting the lifting distance by using Hall sensors and magnets in the related art has the following disadvantages: it is necessary to use two magnets and one Hall sensor, or two Hall sensors and one magnet, resulting in a relatively high cost for lifting distance detection; the magnet can easily interfere with the surrounding current circuit and magnetic device circuit, and can also magnetize the surrounding metal devices, causing the Hall sensor to make incorrect judgments and the lifting camera function to fail; the layout area is large, which is not conducive to the stacking of electronic equipment and the weight reduction of the entire machine.

[0037] In order to solve the technical problems existing in the related technology, please refer to Figure 1 and Figure 2 , Figure 1 is a partial schematic diagram of a structure of an electronic device provided by an embodiment of the present invention, Figure 2 is a structural schematic diagram of a camera module provided by an embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the electronic device 100 provided in this embodiment includes a camera module 101 and a lifting structure 102;

[0038] The lifting structure 102 is disposed in the housing of the electronic device 100, one end of the lifting structure 102 is fixedly connected to the camera module 101, and the other end is electrically connected to the electronic device 100, and the lifting structure 102 is used to lift and move the camera module 101 relative to the electronic device 100;

[0039] The camera module 101 includes a camera 1011 and a flexible circuit board 1012, one end of the flexible circuit board 1012 is electrically connected to the camera 1011, and the other end is electrically connected to the electronic device 100;

[0040] The flexible circuit board 1012 has a bending area A. A deformation detection component 10121 is disposed in the bending area A. The deformation detection component 10121 is used to detect the deformation amount of the bending area A so that the electronic device 100 can control the lifting structure 102 according to the deformation amount.

[0041] In this embodiment, the flexible circuit board 1012 provided in this embodiment has a bending area A that can be bent, so that when the lifting structure 102 causes the camera module 101 to move up and down, the bending area A of the flexible circuit board 1012 can be bent or straightened to ensure the normal lifting function of the camera module 101. For example, when the camera module 101 moves from inside the electronic device 100 to outside the electronic device 100, the bending area A in the flexible circuit board 1012 in a bent state will straighten as the camera module 101 rises outward; when the camera module 101 shrinks from outside the electronic device 100 to inside the electronic device 100, the bending area A in the flexible circuit board 1012 in a straightened state will bend as the camera module 101 shrinks inward. In this way, the normal lifting function of the camera module 101 can be effectively guaranteed.

[0042] For details, please refer to Figure 2 , Figure 2 The camera module 101 on the left side is the camera module 101 in a fully extended state of the flexible circuit board 1012. Figure 2The camera module 101 on the right side is the camera module 101 in a bent state of the flexible circuit board 1012. When the camera module 101 moves from the inside of the electronic device 100 to the outside of the electronic device 100, that is, Figure 2 The camera module 101 on the middle right side moves upward until a Figure 2 When the camera module 101 is shown on the left side, the deformation amount of the bending area A, that is, the expansion and contraction amount ΔY of the flexible circuit board 1012, can be detected by the deformation detection component 10121, so that the electronic device 100 can determine the current length of the flexible circuit board 1012 according to the expansion and contraction amount ΔY, and whether it reaches the length of the flexible circuit board 1012 in a fully extended state, and when the length of the flexible circuit board 1012 in a fully extended state is reached, the lifting structure 102 is controlled to stop working, thereby realizing precise control of the lifting distance of the camera 1011 without using a Hall sensor, and reducing the manufacturing cost of the electronic device 100.

[0043] In some embodiments, the deformation detection component 10121 provided in this embodiment includes a resistance strain gauge (not shown in the figure) and a deformation output unit (not shown in the figure);

[0044] The resistance strain gauge is attached to the bending area A, and the resistance strain gauge is used to change the resistance value of the resistance strain gauge according to the deformation generated in the bending area A;

[0045] The deformation output unit is electrically connected to the resistance strain gauge and the electronic device 100 respectively, and is used to output the deformation corresponding to the flexible circuit board 1012 according to the relative change of the resistance value of the resistance strain gauge.

[0046] In this embodiment, the resistance strain gauge provided in this embodiment can be mechanically deformed under the action of external force, and its resistance value also changes with the size of the deformation. Therefore, the relative changes of different resistance values ​​and the corresponding deformation of the flexible circuit board 1012 can be obtained in advance, and a mapping relationship table of the relative change of resistance value-the deformation of the flexible circuit board 1012 can be constructed, so that in the actual application process, the deformation corresponding to the flexible circuit board 1012 can be determined directly according to the detected relative change of resistance value and the pre-constructed mapping relationship table of the relative change of resistance value-the deformation of the flexible circuit board 1012. Then, it is possible to determine whether the length of the current flexible circuit board 1012 reaches the length in the fully straightened state according to the deformation, and control the lifting structure 102 to stop working when it reaches the length, so as to achieve precise control of the lifting distance of the camera 1011.

[0047] In one implementation, the resistance strain gauge provided in this embodiment includes a flexible substrate (not shown in the figure) and a resistance strain sensor (not shown in the figure);

[0048] The resistance strain sensor is attached to the first side of the flexible substrate, the second side of the flexible substrate is attached to the bending area A, and the first side and the second side are two opposite sides;

[0049] The resistance strain sensor is used to change the resistance value of the resistance strain gauge according to the deformation of the flexible substrate.

[0050] In this embodiment, the resistance strain sensor provided in this embodiment is attached to a flexible substrate, and can be deformed together with the flexible substrate under the action of an external force, thereby changing the resistance value of the resistance strain sensor. Optionally, the resistance strain gauge provided in this embodiment may also include a protective film (not shown in the figure), which covers the resistance strain sensor and is used to protect the resistance strain sensor, prevent the resistance strain sensor from being damaged by foreign objects, extend the service life of the resistance strain sensor, and also ensure the accuracy of the resistance strain sensor changing the resistance value.

[0051] In another embodiment, see Figure 3 , Figure 3 is a schematic diagram of a structure in which a deformation output unit provided by an embodiment of the present invention is connected to a resistance strain gauge, such as Figure 3 As shown, the deformation output unit provided in this embodiment includes a bridge circuit, a differential amplifier, a voltage detector and a deformation converter;

[0052] The bridge circuit is electrically connected to the resistance strain gauge and the differential amplifier respectively, and the bridge circuit is used to convert the relative change of the resistance value of the resistance strain gauge into the voltage change;

[0053] The differential amplifier is also electrically connected to the voltage detector. The differential amplifier is used to amplify the voltage variation and transmit it to the voltage detector. The voltage detector is used to detect the voltage value of the amplified voltage variation to obtain the relative variation of the voltage value.

[0054] The deformation converter is electrically connected to the voltage detector and is used for converting the relative change of the voltage value into the deformation corresponding to the flexible circuit board.

[0055] Specifically, this embodiment can pre-acquire different relative changes in voltage values ​​and the corresponding deformation amounts of the flexible circuit board, and construct a mapping relationship table of the relative change in voltage value-the deformation amount of the flexible circuit board. Therefore, in the actual application process, the corresponding deformation amount of the flexible circuit board can be determined directly according to the measured relative change in voltage value and the pre-constructed mapping relationship table of the relative change in voltage value-the deformation amount of the flexible circuit board, thereby realizing precise control of the lifting distance of the camera.

[0056] Specifically, the bridge circuit provided in this embodiment may be a half-bridge circuit or a full-bridge circuit. The voltage detector provided in this embodiment may be an ADC analog-to-digital converter.

[0057] As an optional embodiment, the camera module 101 provided in this embodiment further includes a rotating structure (not shown in the figure);

[0058] The camera 1011 is disposed on the rotating structure, and the rotating structure is fixedly connected to the lifting structure 102;

[0059] The rotating structure is used to rotate the camera 1011 to a different position when the camera 1011 is raised outside the electronic device 100.

[0060] Thus, by arranging the camera 1011 on the rotating structure, the camera 1011 can be rotated to different positions when the camera 1011 is raised outside the electronic device 100, for example, the camera 1011 can be rotated to be used as a front camera 1011, or the camera 1011 can be rotated to be used as a rear camera 1011. Thus, only one camera 1011 is needed to realize the functions of the front camera 1011 and the rear camera 1011 as required, which can reduce the number of cameras 1011 and reduce production costs on the one hand, and combine the front camera 1011 and the rear camera 1011 into one, which can reduce the difficulty of processing.

[0061] It should be noted that the rotating structure provided in this embodiment is not limited to rotating the camera 1011 forward or backward to realize the functions of the front camera 1011 and the rear camera 1011, but can also rotate the camera 1011 in any direction and at any angle, without specific limitation here.

[0062] In summary, this embodiment provides an electronic device, which includes a camera module and a lifting structure, the lifting structure is arranged in the housing of the electronic device, one end of the lifting structure is fixedly connected to the camera module, and the other end is electrically connected to the electronic device, the lifting structure is used to lift and move the camera module relative to the electronic device, the camera module includes a camera and a flexible circuit board, one end of the flexible circuit board is electrically connected to the camera, and the other end is electrically connected to the electronic device, the flexible circuit board has a bending area, a deformation detection component is provided in the bending area, and the deformation detection component is used to detect the deformation amount of the bending area, so that the electronic device can control the lifting structure according to the deformation amount. By adopting the embodiment of the present invention, it is possible to achieve precise control of the lifting distance of the camera without using a Hall sensor, and reduce the manufacturing cost of the electronic device.

[0063] In some embodiments, in order to solve the same technical problem, the present invention also provides a control method of an electronic device, please also refer to Figure 1 , Figure 2 as well as Figure 4 , Figure 4 is a flow chart of a control method of an electronic device provided by an embodiment of the present invention. Figure 1 , Figure 2 , Figure 4 As shown, an embodiment of the present invention also provides a control method for an electronic device, wherein the electronic device includes a camera module and a lifting structure; the lifting structure is arranged in a housing of the electronic device, one end of the lifting structure is fixedly connected to the camera module, and the other end is electrically connected to the electronic device, and the lifting structure is used to lift and move the camera module relative to the electronic device; the camera module includes a camera and a flexible circuit board, one end of the flexible circuit board is electrically connected to the camera, and the other end is electrically connected to the electronic device; the flexible circuit board has a bending area, and a deformation detection component is arranged in the bending area, and the deformation detection component is used to detect the deformation amount of the bending area, so that the electronic device can control the lifting structure according to the deformation amount;

[0064] The control method of the electronic device provided in this embodiment includes steps 401 to 402;

[0065] Step 401, obtaining a deformation amount detected by a deformation detection component, where the deformation amount is used to characterize the expansion and contraction amount of a flexible circuit board in an electronic device.

[0066] In this embodiment, the deformation detection component provided in this embodiment includes a resistance strain gauge and a deformation variable output unit; the resistance strain gauge is attached to the bending area, and the resistance strain gauge is used to change the resistance value of the resistance strain gauge according to the deformation generated in the bending area; the deformation variable output unit is electrically connected to the resistance strain gauge and the electronic device respectively, and the deformation variable output unit is used to output the deformation variable corresponding to the flexible circuit board according to the relative change in the resistance value of the resistance strain gauge. Specifically, the steps for obtaining the deformation variable detected by the deformation detection component provided in this embodiment may include: obtaining the current first resistance value and original resistance value of the resistance strain gauge, and the original resistance value is the resistance value of the resistance strain gauge of the flexible circuit board in a fully stretched state; according to the first resistance value and the original resistance value, determining the relative change in the resistance value of the resistance strain gauge; inputting the relative change in the resistance value into the deformation variable output unit to obtain the deformation variable corresponding to the flexible circuit board.

[0067] Specifically, the principle of the deformation variable output unit provided in the present embodiment outputting the deformation variable of the flexible circuit board is as follows: according to the relative change in the resistance value of the resistance strain gauge and the relationship between the resistance value of the resistance strain gauge and the resistance wire in the resistance strain gauge, the relative change in the length of the resistance wire in the resistance strain gauge is determined; according to the relative change in the length of the resistance wire in the resistance strain gauge, the relative change in the voltage value of the resistance strain gauge is measured, and thus the deformation variable corresponding to the flexible circuit board is determined according to the relative change in the voltage value and a preset mapping relationship table of the relative change in the voltage value-the deformation variable of the flexible circuit board.

[0068] In this embodiment, when the resistance strain gauge provided in this embodiment undergoes mechanical deformation, the resistance wire in the resistance strain gauge will also undergo deformation, thereby causing the resistance value of the resistance strain gauge to change. Specifically, the relationship between the resistance value change of the resistance strain gauge provided in this embodiment and the resistance wire change is:

[0069]

[0070] Wherein, ΔR / R is the relative change of the resistance value of the resistance strain gauge, K is the strain sensitivity coefficient of the resistance strain gauge, and ε=Δl / l is the relative change of the resistance wire length.

[0071] It should be noted that the strain sensitivity coefficient of the resistance strain gauge varies with the material of the resistance strain gauge. Specifically, the strain sensitivity coefficient of the same resistance strain gauge is fixed. Optionally, the strain sensitivity coefficient of the resistance strain gauge provided in this embodiment can be 2.

[0072] The deformation output unit provided in this embodiment may include a bridge circuit, and the relative change of the voltage value of the resistance strain gauge can be measured by the bridge circuit. Specifically, the bridge circuit provided in this embodiment measures the voltage value of the resistance strain gauge according to the following formula:

[0073]

[0074] Among them, U is the measured voltage value of the resistance strain gauge, E is the DC power supply voltage of the bridge, and ε is the relative change in the length of the resistance wire.

[0075] The relative change in the voltage value of the resistance strain gauge can be determined through the bridge circuit, and then the deformation amount corresponding to the flexible circuit board can be determined according to the preset mapping relationship table of the relative change in the voltage value-the deformation amount of the flexible circuit board. Specifically, this embodiment can pre-acquire different relative changes in voltage values ​​and the corresponding deformation amount of the flexible circuit board, and construct a mapping relationship table of the relative change in voltage value-the deformation amount of the flexible circuit board, so that in the actual application process, the deformation amount corresponding to the flexible circuit board can be directly determined according to the measured relative change in voltage value and the pre-constructed mapping relationship table of the relative change in voltage value-the deformation amount of the flexible circuit board, so as to achieve precise control of the lifting distance of the camera.

[0076] Compared with the related methods of using Hall sensors and magnets to detect changes in the lifting distance of the camera, this embodiment converts the changes in the lifting distance of the camera into changes in voltage values, which can not only effectively reduce the interference of the magnet on the surrounding current circuits and magnetic device circuits, but also reduce the risk of interference caused by the Hall sensor in the process of detecting the lifting distance of the camera, while greatly reducing the manufacturing cost of the electronic equipment.

[0077] Step 402: Control the lifting structure according to the deformation amount and the first length of the flexible circuit board, where the first length is the length of the flexible circuit board in a straightened state.

[0078] In some embodiments, the step of controlling the lifting structure according to the deformation amount and the first length of the flexible circuit board provided in this embodiment may include: adding the deformation amount to the second length of the flexible circuit board to obtain the current third length of the flexible circuit board, the second length being the length of the flexible circuit board when the lifting structure is fully retracted in the electronic device; when the third length is equal to the first length, controlling the lifting structure to stop working.

[0079] It should be noted that each time the camera module provided in this embodiment is lifted and moved, it is converted from a fully retracted state in which the camera module is fully retracted inside the electronic device to a fully extended state in which the camera module is fully raised outside the electronic device, or from a fully extended state to a fully retracted state. This embodiment is mainly to avoid the situation in which the camera module continues to rise after rising from a fully retracted state to a fully extended state. Therefore, the deformation amount corresponding to the flexible circuit board determined in this embodiment can be the expansion and contraction amount of the flexible circuit board during the process of the camera module rising from a fully retracted state. In this way, the length of the flexible circuit board when the camera module is in a fully retracted state can be added to the determined expansion and contraction amount, and compared with the first length of the flexible circuit board. When they are equal, it can be determined that the current camera module has reached a fully extended state, thereby controlling the lifting structure to stop working and realizing precise control of the camera lifting.

[0080] In summary, this embodiment provides a control method for an electronic device, including: obtaining a deformation amount detected by a deformation detection component, the deformation amount is used to characterize the expansion and contraction amount of a flexible circuit board in an electronic device, and controlling a lifting structure according to the deformation amount and a first length of the flexible circuit board, wherein the first length is the length of the flexible circuit board in a straightened state. This method can achieve precise control of the lifting distance of a camera without using a Hall sensor, and reduce the manufacturing cost of the electronic device.
