Description

Technical Field

[0001] The present invention relates to the field of imaging technologies, and in particular, to an imaging module and an electronic device. Background Art

[0002] In related technologies, in order to improve the imaging effect of an imaging module, electronic devices such as mobile phones and tablet computers usually design the aperture of the imaging module as a variable aperture. However, in order to be able to change the size of the aperture, such an imaging module usually needs to reserve a large number of pins for electrical connection, resulting in a large number of routing paths, which is likely to increase the difficulty of the routing layout of the imaging module. Summary of the Invention

[0003] Embodiments of the present invention disclose an imaging module and an electronic device, which can reduce the number of routing paths during circuit connection while realizing the change of the aperture size of the imaging module, and facilitate the routing layout of the imaging module.

[0004] To achieve the above object, in a first aspect, the present invention discloses an imaging module, which includes a circuit board structure, a first driving component, a lens component, a first conductive member, and an aperture structure. The first driving component is electrically connected to the circuit board structure. The lens component has an optical axis, and the lens component is connected to the first driving component. The lens component can move relative to the first driving component under the driving action of the first driving component. The first conductive member is disposed on a side of the first driving component away from the circuit board structure, and the first conductive member is electrically connected to the first driving component. The aperture structure includes a second driving component and an aperture component. The second driving component is disposed on a side of the first conductive member away from the first driving component. The second driving component is provided with a first power connection portion, and the first power connection portion is electrically connected to the first conductive member to realize the electrical connection between the first driving component and the second driving component. The aperture component is connected to the second driving component, and the aperture component can move under the driving action of the second driving component to change the size of the aperture of the aperture component.

[0005] In this way, an aperture of corresponding size can be used according to the actual requirements of the scene to improve the imaging effect of the camera module. At the same time, by arranging a first conductive member between the first driving component and the second driving component of the aperture structure, the first conductive member is used to realize the electrical connection between the second driving component of the aperture structure and the first driving component, so that the second driving component of the aperture structure can be electrically connected to the circuit board structure through the first driving component. With such a design, the second driving component and the first driving component of the aperture structure can share the same pin on the circuit board structure, without additionally arranging a pin on the circuit board structure to be electrically connected to the second driving component of the aperture structure. The circuits of the second driving component and the first driving component of the aperture structure are integrated together, thereby reducing the number of routing paths during circuit connection and facilitating the circuit layout of the camera module.

[0006] As an optional implementation manner, in the embodiment of the first aspect of the present invention, the first driving component includes a base, a housing, an elastic member, a carrier, and a power component. The base is electrically connected to the circuit board structure. The housing is connected to the base and forms an accommodation space. The elastic member is located in the accommodation space and connected to the base. The elastic member is a conductive member, and the elastic member is electrically connected to the first conductive member and the base respectively. The carrier is located in the accommodation space and connected to the elastic member. The carrier is used to carry the lens assembly. The power component is arranged in the accommodation space. The power component is electrically connected to the elastic member to realize the electrical connection between the power component and the base. The power component is used to drive the carrier to move relative to the base so that the lens assembly can move relative to the base. In this implementation manner, the first conductive member is electrically connected to the circuit board structure through the elastic member and the base of the first driving component, so as to integrate the circuits of the second driving component and the first driving component, thereby reducing the number of routing paths during circuit connection and facilitating the circuit layout of the camera module.

[0007] As an optional implementation manner, in the embodiment of the first aspect of the present invention, the elastic member includes a first elastic sheet and a second elastic sheet. The first elastic sheet and the second elastic sheet are respectively connected to the base, and the first elastic sheet and the second elastic sheet are arranged at intervals along the optical axis direction;

[0008] The first elastic sheet is electrically connected to the first conductive member and the base respectively, or the first conductive member is electrically connected to the carrier, and the second elastic sheet is electrically connected to the carrier and the base respectively;

[0009] The power component is electrically connected to the first elastic sheet or the second elastic sheet to realize the electrical connection between the power component and the base.

[0010] When the elastic member includes a first elastic piece and a second elastic piece, the first conductive member can be electrically connected to the base through the first elastic piece, or can be electrically connected to the base through the second elastic piece, and the power component can also be electrically connected to the base through the first elastic piece or the second elastic piece. In this way, the components of the original first driving assembly can be used to integrate the circuits of the second driving assembly and the first driving assembly, without the need to add additional power connection components. The structure is simple, which is convenient for the assembly of the camera module and will not increase the overall volume of the camera module, which is beneficial to the miniaturization design of the camera module.

[0011] As an alternative embodiment, in the embodiment of the first aspect of the present invention, the first conductive member is in a ring structure, and the first conductive member surrounds the outer periphery of the lens assembly. In the direction perpendicular to the optical axis, the first conductive member has a first portion protruding from the second driving assembly, and the first portion is electrically connected to the first power connection portion to realize the electrical connection between the first conductive member and the second driving assembly, so that the electrical connection point between the first power connection portion and the first conductive member can be located outside the second driving assembly, avoiding the second driving assembly from blocking the electrical connection point between the first power connection portion and the first conductive member, thus facilitating the operation to realize the electrical connection between the first power connection portion of the second driving assembly and the first conductive member.

[0012] As an alternative embodiment, in the embodiment of the first aspect of the present invention, a first insertion portion is provided on the surface of the first conductive member facing the first driving assembly, and a second insertion portion is provided at the position of the first driving assembly corresponding to the first insertion portion, and the second insertion portion is inserted into the first insertion portion. Compared with the connection method of surface-to-surface fitting between the first conductive member and the first driving assembly, by providing the first insertion portion on the first conductive member and the second insertion portion on the first driving assembly, the insertion effect of the first insertion portion and the second insertion portion can be utilized to prevent the first conductive member from sliding relative to the first driving assembly during assembly, thereby improving the connection stability between the first conductive member and the first driving assembly.

[0013] As an alternative embodiment, in the embodiment of the first aspect of the present invention, the aperture assembly includes a plurality of aperture blades arranged around the optical axis to form the aperture, and each aperture blade is respectively connected to the second driving assembly and is located on the side of the second driving assembly away from the first conductive member;

[0014] The second driving assembly includes a fixed portion and a movable portion. The fixed portion is provided on the side of the first conductive member away from the first driving assembly, and the movable portion is provided on the side of the fixed portion away from the first conductive member. The aperture blade is connected to the movable portion, and the first power connection portion is provided on the fixed portion;

[0015] One side of the fixed part close to the movable part is provided with a coil, the coil is electrically connected to the first power connection part, one side of the movable part close to the fixed part is provided with a magnetic component, the magnetic component is arranged corresponding to the coil, and the coil is used to generate a thrust on the magnetic component when electrified, so that the magnetic component drives the movable part to rotate around the optical axis to drive the aperture blade to rotate, so as to change the size of the aperture. The aperture with a corresponding size can be used according to the actual requirements of the scene to improve the imaging effect of the camera module.

[0016] As an optional implementation manner, in the embodiment of the first aspect of the present invention, the second driving component further includes a circuit board, the circuit board is arranged on the fixed part and located between the fixed part and the movable part, the circuit board is provided with the first power connection part, and the coil is arranged on the circuit board. The coil is arranged on the fixed part through the circuit board, and at the same time, it can also be electrically connected to the first conductive part through the first power connection part on the circuit board, so that the circuit board has the functions of mechanical connection and electrical connection at the same time, thereby making the structure of the second driving component more compact, and then realizing the reasonable layout of the internal space of the camera module, achieving the miniaturized design of the camera module.

[0017] As an optional implementation manner, in the embodiment of the first aspect of the present invention, in the direction perpendicular to the optical axis, the circuit board extends outward with a first extension part, and the coil is arranged on the first extension part. The circuit board only extends outward with a first extension part at the position for carrying the coil, which can reduce the occupied area of the circuit board on the fixed part while using a larger coil to ensure that the coil has a larger thrust, so that the fixed part can vacate a position to set other components, and can make full use of the space on the side of the fixed part for carrying the circuit board. In addition, the unused space of the fixed part can also be omitted, so that a smaller fixed part can be used.

[0018] As an optional implementation manner, in the embodiment of the first aspect of the present invention, a position sensor is further arranged on one side of the fixed part close to the movable part, the position sensor is electrically connected to the first power connection part, and the position sensor is used to detect the rotation angle of the aperture blade. In this way, the relative position change of the aperture blade in the rotation direction can be feedback, forming a closed-loop position feedback control system. This closed-loop control has the characteristic of accurately driving the aperture blade to a specified position. Through the operation feedback of the position sensor, the size of the input current can be changed to control the target rotation angle of the aperture blade, and finally control the opening and closing degree of the aperture blade to achieve the effect of continuously variable aperture.

[0019] As an alternative implementation, in the embodiment of the first aspect of the present invention, a driving chip is further provided on one side of the fixing part close to the moving part, the position sensor is integrated in the driving chip, and the driving chip is electrically connected to the first conductive member. It can be understood that in the related art, in order to realize the power supply and signal connection of the position sensor, usually six pins need to be reserved for electrical connection. By integrating the position sensor on the driving chip, the power supply pins and signal pins of the position sensor can be integrated together, reducing the number of pins.

[0020] As an alternative implementation, in the embodiment of the first aspect of the present invention, the fixing part is provided with an avoidance hole, and the position sensor is built in the avoidance hole. Since the thickness of the position sensor is generally thicker than that of the coil, if both the position sensor and the coil are arranged on the side of the fixing part facing the moving part, the position sensor will protrude from the coil, which may affect the cooperation between the coil and the magnetic component. Therefore, by providing an avoidance hole in the fixing part to place the position sensor, a height difference exists between the position sensor and the coil in the optical axis direction, avoiding the position sensor protruding from the coil, which is beneficial to ensuring the cooperation between the coil and the magnetic component. At the same time, since the position sensor is built in the avoidance hole, the space utilized by the position sensor is the internal space of the avoidance hole of the fixing part, thereby effectively reducing the overall thickness of the camera module in the optical axis direction, which is beneficial to the miniaturization design of the camera module.

[0021] As an alternative implementation, in the embodiment of the first aspect of the present invention, the moving part is provided with a first groove and a second groove, the magnetic component is adhesively bonded in the first groove, the second groove communicates with the first groove, and the second groove is used to accommodate the adhesive overflowing from the first groove to avoid the occurrence of adhesive overflow.

[0022] As an alternative implementation, in the embodiment of the first aspect of the present invention, the aperture assembly further includes a ball, the ball is arranged between the moving part and the fixing part, the ball is in contact connection with the moving part and the fixing part, and when the moving part rotates around the optical axis, the ball can roll relative to the fixing part to reduce the friction between the moving part and the fixing part, facilitating the rotation of the moving part around the optical axis relative to the fixing part.

[0023] As an alternative implementation, in the embodiment of the first aspect of the present invention, the aperture assembly further includes a magnetic conductive component, the magnetic conductive component is arranged on the fixing part, and the magnetic conductive component is mutually attracted and connected with the magnetic component, so that the ball can maintain contact connection with the moving part and the fixing part, and thus when the moving part rotates around the optical axis, the ball can keep rolling relative to the fixing part.

[0024] As an alternative embodiment, in the embodiment of the first aspect of the present invention, the magnetic conductive component is in an annular structure, so that when the movable part rotates relative to the fixed part around the optical axis, the magnetic component can always be correspondingly arranged with the magnetic conductive component and be attractively connected to the magnetic component.

[0025] As an alternative embodiment, in the embodiment of the first aspect of the present invention, the fixed part is provided with a first guiding part, and the movable part is provided with a second guiding part. The first guiding part and the second guiding part jointly define a rolling space for the rolling of the ball, facilitating the ball to roll relative to the fixed part along a preset track, that is, the first guiding part and the second guiding part can play a role in limiting and guiding the ball.

[0026] As an alternative embodiment, in the embodiment of the first aspect of the present invention, a fixing rod is provided on the surface of the fixed part facing the aperture blades. The number of the fixing rods is adapted to the number of the aperture blades. One end of each aperture blade is sleeved on the corresponding fixing rod. A pushing rod is provided on the surface of the movable part facing the aperture blades. The number of the pushing rods is adapted to the number of the aperture blades. One end of each aperture blade is also sleeved on the corresponding pushing rod. Thus, when the coil is energized, the pushing rod rotates around the optical axis to push the aperture blade to rotate around the fixing rod, so as to change the size of the aperture.

[0027] As an alternative embodiment, in the embodiment of the first aspect of the present invention, the aperture assembly further includes a limiting blade. The limiting blade is located on one side of the aperture blade close to the movable part and / or on one side of the aperture blade far from the movable part. The limiting blade penetrates through the fixing rod. The limiting blade is provided with a limiting hole. The pushing rod penetrates through the limiting hole, so that the limiting hole can be used to limit the moving space of the pushing rod. The limiting blade can limit the moving space of each aperture blade. At the same time, it can prevent each aperture blade from being deformed or sagging during rotation, which may affect the light transmission effect.

[0028] In a second aspect, the present invention discloses an electronic device, and the electronic device includes the imaging module as described in the first aspect above. It can be understood that if the electronic device includes the imaging module of the first aspect, the electronic device has the beneficial effects of the imaging module of the first aspect.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] The camera module and the electronic device provided by the embodiments of the present invention can change the aperture size of the aperture component by setting the second driving component, so that the corresponding aperture size can be used according to the actual requirements of the scene to improve the imaging effect of the camera module. At the same time, by setting the first conductive member between the first driving component and the second driving component of the aperture structure, the first conductive member is used to realize the electrical connection between the second driving component of the aperture structure and the first driving component, so that the second driving component of the aperture structure can be electrically connected to the circuit board structure through the first driving component. With such a design, the second driving component and the first driving component of the aperture structure can share the same pin on the circuit board structure, and there is no need to additionally set a pin on the circuit board structure to be electrically connected to the second driving component of the aperture structure. Integrating these two circuits of the second driving component and the first driving component of the aperture structure can reduce the number of wiring paths during circuit connection and facilitate the circuit layout of the camera module.

[0057] An embodiment of the present invention discloses an electronic device, and the electronic device includes a camera module. Among them, the electronic device may be, but is not limited to, information terminal devices such as mobile phones, tablet computers, laptop computers, wearable smart devices (such as smart watches, smart bracelets, etc.), vehicle-mounted devices, or personal digital assistants (PDAs), or other electronic devices with a photographing function. The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0058] Please refer to Figure 1 and Figure 2, embodiments of the present invention disclose an imaging module. The imaging module 100 includes a circuit board structure 1, a first driving component 2, a lens component 3, a first conductive member 4, and a diaphragm structure 5. The first driving component 2 is electrically connected to the circuit board structure 1. The lens component 3 has an optical axis L, and the lens component 3 is connected to the first driving component 2 so that the lens component 3 can move relative to the first driving component 2 under the driving action of the first driving component 2. The first conductive member 4 is disposed on a side of the first driving component 2 away from the circuit board structure 1, and the first conductive member 4 is electrically connected to the first driving component 2. The diaphragm structure 5 includes a second driving component 5a and a diaphragm component 5b. The second driving component 5a is disposed on a side of the first conductive member 4 away from the first driving component 2. The second driving component 5a is provided with a first power connection portion 50. The first power connection portion 50 is electrically connected to the first conductive member 4 to realize the electrical connection between the first driving component 2 and the second driving component 5a. The diaphragm component 5b is connected to the second driving component 5a, and the diaphragm component 5b can move under the driving action of the second driving component 5a to change the size of the aperture of the diaphragm component 5b.

[0059] Exemplarily, the diaphragm component 5b may include a plurality of aperture blades 51 disposed around the optical axis to form an aperture. Each aperture blade 51 is respectively connected to the second driving component 5a and is located on a side of the second driving component 5a away from the first conductive member 4, and each aperture blade 51 can move under the driving action of the second driving component 5a to change the size of the aperture. For example, as Figure 3A and Figure 3B shown, Figure 3A and Figure 3B the sizes of the apertures 200 shown are different.

[0060] As can be seen from the above, when the second driving component 5a is powered on, it can drive each aperture blade 51 to rotate around the optical axis to change the size of the aperture 200, so that the corresponding size of the aperture 200 can be used according to the actual requirements of the scene to improve the imaging effect of the imaging module 100; at the same time, by providing the first conductive member 4 between the first driving component 2 and the second driving component 5a, the electrical connection between the second driving component 5a and the first driving component 2 is realized by using the first conductive member 4, so that the second driving component 5a can be electrically connected to the circuit board structure 1 through the first driving component 2. With such a design, the second driving component 5a and the first driving component 2 can share the same pin on the circuit board structure 1, and there is no need to additionally set other pins to be electrically connected to the second driving component 5a, that is, the two circuits of the second driving component 5a and the first driving component 2 can be integrated together, thereby reducing the number of routing paths during circuit connection and facilitating the circuit layout of the imaging module 100.

[0061] It can be known that the above-mentioned first driving component 2 can be an open-loop motor, a closed-loop motor, or a central motor, such as an AF (Auto Focus) motor or an OIS (Optical Image Stabilization) motor, etc. The above-mentioned circuit board structure 1 can include a first main board and an image sensor disposed on the first main board. The image sensor can receive the light of the lens assembly 3 to form an image, so as to realize the photographing function of the camera module 100. Moreover, the circuit board structure 1 can be electrically connected to the second main board of the electronic device through the first main board, so that the imaging information of the image sensor can be transmitted to the second main board of the electronic device. Among them, the image sensor can be a complementary metal oxide semiconductor image sensor (Complementary Metal Oxide Semiconductor, CMOS), or a charge-coupled image sensor (Charge Couple Device, CCD), etc.

[0062] Furthermore, as can be seen from the above, the above-mentioned aperture blades 51 can be multiple, that is, the number of aperture blades 51 is at least 2, for example, 2, 3, 4, 5 or more, such as Figure 4A and Figure 4B shown, Figure 4A shows that the number of aperture blades is 3, Figure 4B shows that the number of aperture blades is 5. It can be understood that the number of aperture blades 51 can be adjusted according to specific circumstances or calibrated through actual tests.

[0063] By adopting the method of multiple aperture blades 51, the multiple aperture blades 51 can stack out the shape of a continuously switched aperture at the same time, achieving the effect of continuously variable aperture, so that it can be adjusted from f 1.4 all the way to f 11, and even can be arbitrarily switched to multiple aperture sizes such as f2.8, f 4, f 5.6, etc., allowing photographers to freely select the aperture sizes required for various scenarios.

[0064] Such as Figure 5 and Figure 6 shown, in some embodiments, the first conductive member 4 can be a ring structure, and the first conductive member 4 surrounds the outer periphery of the lens assembly 3. In the direction perpendicular to the optical axis, such as along Figure 5In the direction indicated by the arrow x, the first conductive member 4 has a first portion 41 protruding from the second driving assembly 5a, and the first portion 41 is electrically connected to the first power connection portion 50 to achieve the electrical connection between the first conductive member 4 and the second driving assembly 5a. In this way, the electrical connection point between the first power connection portion 50 and the first conductive member 4 can be located outside the second driving assembly 5a, avoiding the second driving assembly 5a from blocking the electrical connection point between the first power connection portion 50 and the first conductive member 4, thereby facilitating the operation to achieve the electrical connection between the first power connection portion 50 of the second driving assembly 5a and the first conductive member 4.

[0065] In order to endow the first conductive member 4 with electrical conductivity, the first conductive member 4 can be a metal member or a plastic member with metal wire inside, etc. Compared with the first conductive member 4 being a metal member, when the first conductive member 4 is a plastic member with metal lines inside, it is lighter in weight and better in safety.

[0066] As Figure 6 and Figure 7 shown, in some embodiments, a first insertion portion 42 is provided on the surface of the first conductive member 4 facing the first driving assembly 2, and a second insertion portion 20 is provided at the position of the first driving assembly 2 corresponding to the first insertion portion 42. The second insertion portion 20 is inserted into the first insertion portion 42 to dispose the first conductive member 4 on the first driving assembly 2. Compared with the connection method of surface-to-surface fitting between the first conductive member 4 and the first driving assembly 2, by providing the first insertion portion 42 on the first conductive member 4 and the second insertion portion 20 on the first driving assembly 2, the insertion effect of the first insertion portion 42 and the second insertion portion 20 can be utilized to avoid the relative sliding of the first conductive member 4 with respect to the first driving assembly 2 during assembly, and improve the connection stability between the first conductive member 4 and the first driving assembly 2.

[0067] Please refer to Figure 7 and Figure 8As shown, in some embodiments, the first driving component 2 includes a base 21, a housing 22, an elastic member 23, a carrier 24, and a power component 25. The base is electrically connected to the circuit board structure 1. The housing 22 is connected to the base 21 and forms an accommodation space. The housing 22 is provided with the aforementioned second insertion portion 20 at a position corresponding to the first insertion portion 42. The elastic member 23 is located in the accommodation space and connected to the base 21. The elastic member 23 is a conductive member, and the elastic member 23 is electrically connected to the first conductive member 4 and the base 21 respectively to realize the electrical connection between the second driving component 5a and the circuit board structure 1 to access current, so that the second driving component 5a can move each aperture blade 51 to change the size of the aperture. The carrier 24 is located in the accommodation space and connected to the elastic member 23. The carrier 24 is used to carry the lens assembly 3. The power component 25 is arranged in the accommodation space. The power component 25 is electrically connected to the elastic member 23 to realize the electrical connection between the power component 25 and the base 21, thereby realizing the electrical connection between the power component 25 and the circuit board structure 1 to access current, so that the power component 25 can be used to drive the carrier 24 to move relative to the base 21, so that the lens assembly 3 can move relative to the base 21.

[0068] In other words, the second driving component 5a can be electrically connected to the circuit board structure 1 through the first conductive member 4, the elastic member 23, and the base 21. At the same time, the power component 25 of the first driving component 2 can be electrically connected to the circuit board structure 1 through the elastic member 23 and the base 21, so that the circuits of the second driving component 5a and the first driving component 2 can be integrated together, thereby reducing the number of wire routing paths during circuit connection and facilitating the circuit layout of the camera module 100.

[0069] Further, as Figure 8 shown, the elastic member 23 may include a first elastic sheet 231 and a second elastic sheet 232. The first elastic sheet 231 and the second elastic sheet 232 are respectively connected to the base 21. The first elastic sheet 231 and the second elastic sheet 232 are arranged at intervals along the optical axis direction;

[0070] As an alternative embodiment, as Figure 9 shown, the first elastic sheet 231 may be electrically connected to the first conductive member 4 and the base 21 respectively. That is, the first conductive member 4 can be electrically connected to the circuit board structure 1 through the first elastic sheet 231 and the base 21 in sequence to access current. For example, Figure 9The circuit diagram shown by the dotted line in []. In this embodiment, when the power component 25 drives the carrier 24 to move relative to the base 21, the first conductive member 4 will move relative to the base 21 together with the carrier 24. However, since the first elastic piece 231 is elastic and can deform, when the first conductive member 4 moves relative to the base 21 together with the carrier 24, the first elastic piece 231 will deform, so that the position of the electrical connection between the first elastic piece 231 and the first conductive member 4 can move together with the first conductive member 4, making the position of the electrical connection between the first conductive member 4 and the first elastic piece 231 remain relatively stationary, so that the first conductive member 4 can always maintain electrical connection with the first elastic piece 231. Therefore, compared with the method of using a wire to realize the electrical connection between the first conductive member 4 and the circuit board structure 1 in the related art, the present application uses the first elastic piece 231 to be electrically connected to the first conductive member 4, and there will be no situation of pulling the wire, and the conductivity reliability is higher.

[0071] As another alternative embodiment, as Figure 9 shown, the first conductive member 4 is electrically connected to the carrier 24, and the second elastic piece 232 is electrically connected to the carrier 24 and the base 21 respectively. Then the first conductive member 4 can be electrically connected to the circuit board structure 1 through the carrier 24, the second elastic piece 232, and the base 21 in sequence to access the current. For example, Figure 9 the circuit diagram shown by the dashed line in []. In this embodiment, when the power component 25 drives the carrier 24 to move relative to the base 21, the first conductive member 4 will move together with the carrier 24, and the first conductive member 4 and the carrier 24 can remain relatively stationary, which will not affect the conductivity reliability between the two. Moreover, since the second elastic piece 232 is elastic and can deform, when the first conductive member 4 moves relative to the base 21 together with the carrier 24, the second elastic piece 232 will deform, so that the position of the electrical connection between the second elastic piece 232 and the carrier 24 can move together with the carrier 24, making the position of the electrical connection between the second elastic piece 232 and the carrier 24 remain relatively stationary, so that the carrier 24 can always maintain electrical connection with the second elastic piece 232. Therefore, compared with the method of using a wire to realize the electrical connection between the first conductive member 4 and the circuit board structure 1 in the related art, the present application uses the second elastic piece 232 and the carrier 24 to be electrically connected to the first conductive member 4, and there will be no situation of pulling the wire, and the conductivity reliability is higher.

[0072] The above-mentioned "the first elastic piece 231 is electrically connected to the first conductive member 4" can be understood as: the first elastic piece 231 is in contact electrical connection with the first conductive member 4, or the electrical connection between the first elastic piece 231 and the first conductive member 4 can be realized through conductive members such as wires and metal parts (such as metal bonding wires); "the first elastic piece 231 is electrically connected to the base 21" can be understood as: the electrical connection between the first elastic piece 231 and the base 21 is realized through conductive members such as wires and metal parts (such as metal bonding wires). "The first conductive member 4 is electrically connected to the carrier 24" can be understood as: the electrical connection between the first conductive member 4 and the carrier 24 is realized through conductive members such as wires and metal parts (such as metal bonding wires). "The second elastic piece 232 is electrically connected to the carrier 24" can be understood as: the electrical connection between the second elastic piece 232 and the carrier 24 is realized through conductive members such as wires and metal parts (such as metal bonding wires); "the second elastic piece 232 is electrically connected to the base 21" can be understood as: the electrical connection between the second elastic piece 232 and the base 21 is realized through conductive members such as wires and metal parts (such as metal bonding wires). "The base 21 is electrically connected to the circuit board structure 1" can be understood as: the electrical connection between the base 21 and the circuit board structure 1 is realized through conductive members such as wires, metal parts (such as metal bonding wires), and pins.

[0073] In some embodiments, the power component 25 can be electrically connected to the first elastic piece 231 or the second elastic piece 232 to realize the electrical connection between the power component 25 and the base 21, so as to realize the electrical connection between the power component 25 and the circuit board structure 1 to access current. That is, the power component 25 can be electrically connected to the circuit board structure 1 through the first elastic piece 231 and the base 21 in sequence, or the power component 25 can be electrically connected to the circuit board structure 1 through the second elastic piece 232 and the base 21 in sequence.

[0074] Exemplarily, the power component 25 can include a magnet 251 and a drive coil 252. The magnet 251 and the drive coil 252 are correspondingly arranged. The drive coil 252 is arranged on the carrier 24, and the drive coil 252 can be electrically connected to the circuit board structure 1 through the first elastic piece 231 and the base 21 in sequence, or the drive coil 252 can be electrically connected to the circuit board structure 1 through the second elastic piece 232 and the base 21 in sequence. Thus, the thrust generated when the drive coil 252 is energized can push the carrier 24 to move relative to the base 21, so as to realize the movement of the lens module 3 relative to the base 21.

[0075] As can be seen from the foregoing, the present application mainly uses the original components of the first driving component 2 (such as the first elastic piece 231, the second elastic piece 232, the carrier 24, the base 21, etc.) to integrate the circuits of the second driving component 5a and the first driving component 2, without the need to add additional power connection components. The structure is simple, which is convenient for the assembly of the camera module 100 and does not increase the overall volume of the camera module 100, which is beneficial to the miniaturization design of the camera module 100.

[0076] In the embodiment shown in FIG. 9, both the first elastic pieces 231 and the second elastic pieces 232 can be four. The four first elastic pieces can be located at the four diagonals of the base 21. Similarly, the four second elastic pieces 232 can also be located at the four diagonals of the base 21. Exemplarily, when the first conductive member 4 is electrically connected to one of the first elastic pieces 231, the driving coil 252 can be electrically connected to the first elastic piece 231 electrically connected to the first conductive member 4, or can be electrically connected to the first elastic piece 231 not electrically connected to the first conductive member 4, or can be electrically connected to the second elastic piece 232, and so on. Another example is that when the first conductive member 4 is electrically connected to one of the second elastic pieces 232, the driving coil 252 can be electrically connected to the second elastic piece 232 electrically connected to the first conductive member 4, or can be electrically connected to the second elastic piece 232 not electrically connected to the first conductive member 4, or can be electrically connected to the first elastic piece 231, and so on. There is no limitation in this embodiment.

[0077] Please refer to Figure 10 and Figure 11 , in some embodiments, the second driving assembly 5a includes a fixing part 52 and a movable part 53. The fixing part 52 is arranged on the side of the first conductive member 4 away from the first driving assembly 2, and the movable part 53 is arranged on the side of the fixing part 52 away from the first conductive member 4. The aperture blade 51 is connected to the movable part 53, and the first electrical connection part 50 is arranged on the fixing part 52. Moreover, a magnetic component 531 is arranged on the side of the movable part 53 close to the fixing part 52, a coil 521 is arranged on the side of the fixing part 52 close to the movable part 53, the coil 521 is arranged corresponding to the magnetic component 531, and the coil 521 is electrically connected to the first electrical connection part 50. In this way, the coil 521 can be electrically connected to the first conductive member 4 through the first electrical connection part 50, so as to realize the electrical connection between the coil 521 and the first driving assembly 2. Furthermore, the coil 521 can be electrically connected to the circuit board structure 1, so that the coil 521 can be used to generate a thrust on the magnetic component 531 when powered on, so that the magnetic component 531 drives the movable part 53 to rotate around the optical axis to drive the aperture blade 51 to rotate, so as to change the size of the aperture 200. The aperture 200 with a corresponding size can be used according to the actual requirements of the scene to improve the imaging effect of the camera module 100. Among them, both the fixing part 52 and the movable part 53 can be in a ring structure.

[0078] Specifically, a fixing rod 522 is provided on one side of the fixing part 52 facing the aperture blades 51. The number of the fixing rods 522 is adapted to the number of the aperture blades 51. One end of each aperture blade 51 is sleeved on the corresponding fixing rod 522. A pushing rod 532 is provided on one side of the movable part 53 facing the aperture blades 51. The number of the pushing rods 532 is also adapted to the number of the aperture blades 51. One end of each aperture blade 51 is further sleeved on the corresponding pushing rod 532. Thus, when the coil 521 is energized, the movable part 53 will rotate around the optical axis. At the same time, the pushing rod 532 also rotates around the optical axis to push the aperture blade 51 to rotate around the fixing rod 522, so as to change the size of the aperture 200.

[0079] It can be understood that when the coil 521 is energized, a corresponding magnetic field will be generated around the coil 521. The magnetic component 531 located in the magnetic field will be subjected to the thrust exerted by the magnetic field generated by the coil 521, so that the magnetic component 531 can move along the direction of the magnetic field to drive the movable part 53 to rotate around the optical axis to drive the aperture blade 51 to rotate. Optionally, there may be multiple coils 521, such as 2, 3, 4 or more. The multiple coils 521 can be arranged at intervals and equidistantly along the circumference of the fixing part 52. Correspondingly, there may also be multiple magnetic components 531, and each magnetic component 531 is arranged corresponding to the coil 521, so that each magnetic component 531 can be subjected to a thrust with the same magnitude and in the tangential direction along the rotation direction of the movable part 53, thereby ensuring that the movable part 53 is evenly stressed and rotates smoothly. Among them, the magnetic component 531 can be a magnet, or can be obtained by splicing two magnets with opposite polar directions, or can also be an electromagnet.

[0080] In Figure 10 and Figure 11 In the shown embodiment, the aperture structure 5 further includes a cover body 54. The cover body 54 is connected to the fixing part 52 to form an accommodation space. Components such as the movable part 53 and the aperture blades 51 are located in the accommodation space, so that the cover body 54 and the fixing part 52 form the housing of the aperture structure 5, thereby protecting the internal structure of the aperture structure 5, such as the above-mentioned movable part 53, aperture blades 51 and other components.

[0081] In some embodiments, the aperture assembly 5b further includes a limiting blade 55. The limiting blade 55 is located on one side of the aperture blade 51 close to the movable part 53 and / or on one side of the aperture blade 51 far from the movable part 53, and the limiting blade 55 passes through the fixing rod 522 to be connected to the fixing part 52. The limiting blade 55 is provided with a limiting hole 551, and the pushing rod 532 passes through the limiting hole 551, so that the limiting hole 551 can be used to limit the movement space of the pushing rod 532.

[0082] In some embodiments, the movable part 53 may be provided with a first groove 533, and the magnetic component 531 is disposed in the first groove 533. In this way, at least two surfaces of the magnetic component 531 can be in contact with the movable part 53, which can increase the contact area between the magnetic component 531 and the movable part 53, thereby increasing the connection firmness between the magnetic component 531 and the movable part 53, and preventing the magnetic component 531 from falling off the movable part 53 when a thrust is applied. Exemplarily, the magnetic component 531 may be adhesively bonded to the first groove 533 by an adhesive. The movable part 53 may further be provided with a second groove 534 communicating with the first groove 533, so that the second groove 534 can be used to accommodate the adhesive overflowing from the first groove 533, avoiding the occurrence of glue overflow.

[0083] In some embodiments, the second driving assembly 5a may further include a circuit board 56. The circuit board 56 is disposed on the fixed part 52 and located between the fixed part 52 and the movable part 53. The circuit board 56 is provided with the aforementioned first power connection part 50. The coil 521 is disposed on the circuit board 56 and electrically connected to the circuit board 56, so that the coil 521 can be disposed on the fixed part 52 through the circuit board 56, and at the same time, it can be electrically connected to the first conductive member 4 through the first power connection part 50 on the circuit board 56, enabling the circuit board 56 to have the functions of both mechanical connection and electrical connection, thereby making the structure of the second driving assembly 5a more compact, and further realizing the reasonable arrangement of the internal space of the camera module 100, achieving the miniaturized design of the camera module 100. Among them, the circuit board 56 may be a flexible circuit board.

[0084] Further, in the direction perpendicular to the optical axis, the circuit board 56 may extend outward with a first extension part 561, and the coil 521 is disposed on the first extension part 561. That is to say, the circuit board 56 only extends outward with a first extension part 561 at the position for carrying the coil 521. With such a design, while using a relatively large coil 521 to ensure that the coil 521 has a relatively large thrust, the occupied area of the circuit board 56 on the fixed part 52 can be reduced, so that the fixed part 52 can vacate a position to dispose other components, making full use of the space on the side of the fixed part 52 for carrying the circuit board 56, and at the same time, the unused space of the fixed part 52 can be omitted, thereby enabling the use of a smaller fixed part 52.

[0085] In some embodiments, a position sensor 523, such as a Hall position sensor 523, is further provided on one side of the fixing portion 52 close to the movable portion 53. The position sensor 523 is electrically connected to the first power connection portion 50. In this way, the position sensor 523 can be electrically connected to the first conductive member 4 through the first power connection portion 50, so as to realize the electrical connection between the position sensor 523 and the first driving assembly 2. Furthermore, the position sensor 523 can be electrically connected to the circuit board structure 1 to access current, so that the position sensor 523 can be used to detect the rotation angle of the aperture blade 51. Thus, the relative position change of the aperture blade 51 in the rotation direction can be fed back to form a closed-loop position feedback control system. This closed-loop control has the characteristic of accurately driving the aperture blade 51 to a specified position. Through the operation feedback of the position sensor 523, the magnitude of the input current can be changed to control the target rotation angle of the aperture blade 51, and finally control the opening and closing degree of the aperture blade 51 to achieve the effect of continuously variable aperture.

[0086] Furthermore, the fixing portion 52 is provided with an avoidance hole 524, and the position sensor 523 is disposed inside the avoidance hole 524. Since the thickness of the position sensor 523 is generally thicker than that of the coil 521, if both the position sensor 523 and the coil 521 are disposed on the surface of the fixing portion 52 facing the movable portion 53, the position sensor 523 will protrude from the coil 521, which may affect the cooperation between the coil 521 and the magnetic component 531. Therefore, by providing the avoidance hole 524 in the fixing portion 52 to place the position sensor 523, a height difference exists between the position sensor 523 and the coil 521 in the optical axis direction, avoiding the position sensor 523 from protruding from the coil 521, which is beneficial to ensuring the cooperation between the coil 521 and the magnetic component 531. At the same time, since the position sensor 523 is disposed inside the avoidance hole 524, the space utilized by the position sensor 523 is the internal space of the avoidance hole 524 of the fixing portion 52, so that the overall thickness of the camera module 100 in the optical axis direction will not increase, which is beneficial to the miniaturization design of the camera module 100.

[0087] When the second driving assembly 5a includes a circuit board 56, the position sensor 523 can be disposed on the surface of the circuit board 56 facing the fixing portion 52, and the coil 521 can be disposed on the surface of the circuit board 56 facing away from the fixing portion 52. In this way, the space on different surfaces of the circuit board 56 can be fully utilized, and a smaller circuit board 56 can be used.

[0088] Furthermore, a driving chip 523a is further provided on one side of the fixing portion 52 close to the movable portion 53. The position sensor 523 is integrated in the driving chip 523a, and the driving chip 523a is electrically connected to the first conductive member 4. When the second driving assembly 5a includes a circuit board 56, the driving chip 523a can be soldered on the surface of the circuit board 56 facing the fixing portion 52.

[0089] As can be known, in the related art, in order to realize the power supply and signal connection of the position sensor 523, the position sensor 523 usually needs to be provided with 6 pins, and usually 6 corresponding pins also need to be reserved on the circuit board 56 to be correspondingly electrically connected to the 6 pins on the position sensor 523. In the present application, by integrating the position sensor 523 on the drive chip 523a (that is, the two chips are combined into one), the power supply pins and signal pins of the position sensor 523 can be integrated together, that is, the original 6 pins of the position sensor 523 are integrated into 4 pins, reducing the number of pins.

[0090] In some embodiments, as Figure 12 shown, the coil 521 may include a first section 5211 and a second section 5212. The first section 5211 is arranged to extend along the radial direction of the circuit board 56, that is, the first section 5211 can extend along the radial direction of the electrical fixing part 52. The second section 5212 is arranged to extend along the circumferential direction of the circuit board 56, and the second section 5212 can extend along the circumferential direction of the fixing part 52. When the coil 521 is energized, the first section 5211 is used to generate a thrust on the magnetic component 531, so that the magnetic component 531 drives the movable part 53 to rotate around the optical axis to drive the aperture blade 51 to rotate. The coil 521 of the present application can form a closed loop through two first sections 5211 and two second sections 5212, so that the current directions in the two second sections 5212 are opposite to each other, and thus no thrust along the tangential direction of the annular structure on the magnetic component 531 can be generated. In this case, the length L1 of the first section 5211 is greater than the length L2 of the magnetic component 531, so that the magnetic component 531 can be located between the two second sections 5212, so that the thrusts generated by the two second sections 5212 on the magnetic component 531 are also opposite to each other, so that the thrust along the radial direction of the movable part 53 received by the magnetic component 531 is offset.

[0091] Furthermore, the polarity of the magnetic component 531 close to one of the first sections 5211 can be the N pole, and the polarity close to the other first section 5211 can be the S pole. Since the current directions of the two first sections 5211 are opposite, the two first sections 5211 can generate thrusts in the same direction on the magnetic component 531 when energized, so that the coil 521 can push the magnetic component 531 to drive the movable part 53 to rotate.

[0092] Please refer to Figure 13 and Figure 14, In some embodiments, the aperture assembly 5b further includes a ball 57 disposed between the movable portion 53 and the fixed portion 52. The ball 57 is in contact connection with the movable portion 53 and the fixed portion 52. When the movable portion 53 rotates about the optical axis, the ball 57 can roll relative to the fixed portion 52, thereby reducing the frictional force exerted on the movable portion 53 by the fixed portion 52 during rotation and facilitating the rotation of the movable portion 53 about the optical axis relative to the fixed portion 52.

[0093] Further, the aperture assembly 5b further includes a magnetic component 58 disposed on the fixed portion 52. The magnetic component 58 is magnetically attracted to the magnetic component 531, enabling the movable portion 53 and the fixed portion 52 to clamp the ball 57, so that the ball 57 can maintain contact connection with the movable portion 53 and the fixed portion 52. Thus, when the movable portion 53 rotates about the optical axis, the ball 57 can continue to roll relative to the fixed portion 52, reducing the frictional force exerted on the movable portion 53 by the fixed portion 52 during rotation and facilitating the rotation of the movable portion 53 about the optical axis relative to the fixed portion 52.

[0094] Among them, as Figure 15 shown, the magnetic component 58 can be in an annular structure, such that when the movable portion 53 rotates about the optical axis relative to the fixed portion 52, the magnetic component 531 can always be correspondingly arranged with the magnetic component 58 and magnetically attracted to each other, enabling the movable portion 53 and the fixed portion 52 to always clamp the ball 57, so that the ball 57 can always maintain contact connection with the movable portion 53 and the fixed portion 52. The magnetic component 58 can be a permanent magnet or an electromagnet.

[0095] In Figure 15 the embodiment shown, the magnetic component 58 is provided with a first magnetic portion 581 and a second magnetic portion 582 which are spaced apart. Along the circumferential direction of the magnetic component 58, as Figure 15 indicated by the arrow y, the first magnetic portion 581 and the second magnetic portion 582 are respectively located on both sides of the magnetic component 531. When the coil 521 is energized and the magnetic component 531 is pushed to rotate to adjust the size of the aperture 200, it will approach the position of the first magnetic portion 581 or the second magnetic portion 582 and finally stay near the position of the first magnetic portion 581 or the second magnetic portion 582. When the coil 521 is de-energized, due to inertia, the magnetic component 531 still has a tendency to rotate clockwise or counterclockwise. Therefore, the adsorption force between the first magnetic portion 581 or the second magnetic portion 582 and the magnetic component 58 can be utilized, such that when the coil 521 is de-energized, the magnetic component 531 can be adsorbed by the first magnetic portion 581 or the second magnetic portion 582, thereby maintaining the magnetic component 531 at the position before power-off and keeping the movable portion 53 in the state before power-off, so as to maintain the size of the aperture 200 in the state before power-off.

[0096] Please refer to Figure 16 and Figure 17 In some embodiments, a first guiding portion 525 is provided on the fixing portion 52, and a second guiding portion 535 is provided on the movable portion 53. The first guiding portion 525 and the second guiding portion 535 jointly define a rolling space for the ball 57 to roll, facilitating the ball 57 to roll relative to the fixing portion 52 along a preset track. That is, the first guiding portion 525 and the second guiding portion 535 can play a guiding role. Exemplarily, the first guiding portion 525 can be convexly provided on the surface of the fixing portion 52, and the second guiding portion 535 can be concavely provided on the surface of the movable portion 53. Specifically, the first guiding portion 525 has a first surface 5251 and a second surface 5252, and the second guiding portion 535 has a third surface 5351 and a fourth surface 5352. When the fixing portion 52 is connected to the movable portion 53, the first surface 5251 and the third surface 5351 are parallel to each other, and the second surface 5252 and the fourth surface 5352 are parallel to each other, so that the first surface 5251, the second surface 5252, the third surface 5351 and the fourth surface 5352 jointly define the rolling space. When the movable portion 53 rotates, the ball 57 can roll between the second surface 5252 and the fourth surface 5352, and can also roll between the first surface 5251 and the third surface 5351, which can play a guiding role and at the same time make the fixation of the ball 57 more stable.

[0097] The term "parallel to each other" means that the two surfaces are completely parallel, or the angle formed between the two surfaces is within an allowable range (for example, less than 5°).

[0098] Optionally, there can be multiple first guiding portions 525, and the multiple first guiding portions 525 can be arranged on the fixing portion 52 at intervals around the optical axis. Correspondingly, there can also be multiple second guiding portions 535, and the multiple second guiding portions 535 are arranged at intervals and are arranged in one-to-one correspondence with the multiple first guiding portions 525. For example, in the embodiment shown in Figure 16 and Figure 17 , the number of the first guiding portions 525 is 4, the number of the second guiding portions 535 is correspondingly 4, and each first guiding portion 525 corresponds to a second guiding portion 535, so that 4 independent rolling spaces can be defined. That is to say, when there is a ball 57 in each limiting space, since each limiting space is independent of each other, the balls 57 located inside roll in the corresponding limiting spaces in a non-interfering manner. It can be understood that in other embodiments, the number of the first guiding portions 525 and the second guiding portions 535 can be selected according to specific circumstances, or can be calibrated through actual tests. For example, the number of the first guiding portions 525 can be 2, 3, 5, 6 or more than 6, and correspondingly, the number of the second guiding portions 535 can be 2, 3, 5, 6 or more than 6.

[0099] In some embodiments, the fixing portion 52 is further provided with a first limiting portion 526, and the first limiting portion 526 can extend along the radial direction of the fixing portion 52 and away from the first guiding portion 525; the moving portion 53 is further provided with a second limiting portion 536, and the second limiting portion 536 can extend along the radial direction of the moving portion 53 and away from the second guiding portion 535. In the rotation direction of the moving portion 53, the first guiding portion 525 has a first stopping portion 5253, the second guiding portion 535 has a second stopping portion 5353, the first limiting portion 526 has a third stopping portion 5261, and the second limiting portion 536 has a fourth stopping portion 5361. When the moving portion 53 rotates relative to the fixing portion 52, the first stopping portion 5253 and the second stopping portion 5353 abut against each other, and the third stopping portion 5261 and the fourth stopping portion 5361 abut against each other to limit the movement range of the moving portion 53 in the rotation direction.

[0100] Specifically, please further combine Figure 16 and Figure 17 , two first stopping portions 5253 are respectively formed at both ends of the first guiding portion 525 along the rotation direction of the moving portion 53, two second stopping portions 5353 are respectively formed at both ends of the second guiding portion 535 along the rotation direction of the moving portion 53, two third stopping portions 5261 are respectively formed at both ends of the first limiting portion 526 along the rotation direction of the moving portion 53, and two fourth stopping portions 5361 are respectively formed at both ends of the second limiting portion 536 along the rotation direction of the moving portion 53. When the moving portion 53 rotates in one of the clockwise and counterclockwise directions, the first stopping portion 5253 and the second stopping portion 5353 on the same side in this direction can abut against each other, and the third stopping portion 5261 and the fourth stopping portion 5361 on the same side in this direction can abut against each other to limit the movement range of the moving portion 53 rotating relative to the fixing portion 52 around the optical axis; and vice versa.

[0101] Please refer to Figure 16 and Figure 17 , in the radial direction of the moving portion 53, the first guiding portion 525 has a first receiving portion 5254, the second guiding portion 535 has a second receiving portion 5354 (i.e., the aforementioned fourth surface 5352), the first limiting portion 526 has a third receiving portion 5262, and the second limiting portion 536 has a fourth receiving portion 5362. When the moving portion 53 rotates relative to the fixing portion 52, the first receiving portion 5254 and the second receiving portion 5354 can abut against each other, and the third receiving portion 5262 and the fourth receiving portion 5362 can abut against each other to limit the movement range of the moving portion 53 in the radial direction.

[0102] It can be understood that when the movable part 53 rotates in one of the clockwise and counterclockwise directions, the movable part 53 may jump during rotation, resulting in a collision with the fixed part 52. In this case, by the mutual abutment of the first receiving part 5254 and the second receiving part 5354, the movable part 53 can be prevented from jumping towards the direction close to the optical axis. By the mutual abutment of the third receiving part 5262 and the fourth receiving part 5362, the movable part 53 can be prevented from jumping towards the direction away from the optical axis. That is to say, by the mutual abutment of the first receiving part 5254 and the second receiving part 5354, and by the mutual abutment of the third receiving part 5262 and the fourth receiving part 5362, the movement range of the movable part 53 in the radial direction during rotation can be limited.

[0103] In addition, in Figure 17 the illustrated embodiment, the third receiving part 5262 is arranged away from the first receiving part 5254, so that a gap 527 is formed between the first receiving part 5254 and the third receiving part 5262. The fourth receiving part 5362 is arranged away from the second receiving part 5354, so that a convex structure 537 is formed between the movable part 53, the fourth receiving part 5362 and the second receiving part 5354. The convex structure 537 can be received in the gap 527.

[0104] The camera module and the electronic device provided by the embodiment of the present invention. The camera module includes a first driving component and a plurality of aperture blades. Thus, when the second driving component is powered on, it can drive each aperture blade to rotate around the optical axis to change the size of the aperture, so that the corresponding size of the aperture can be used according to the actual requirements of the scene to improve the imaging effect of the camera module. At the same time, by arranging a first conductive member between the first driving component and the second driving component, the first conductive member is used to realize the electrical connection between the second driving component and the first driving component, so that the second driving component can realize the electrical connection with the circuit board structure through the first driving component. With such a design, the second driving component and the first driving component can share the same pin on the circuit board structure, and there is no need to additionally set other pins to be electrically connected to the second driving component. That is to say, the two circuits of the second driving component and the first driving component can be integrated together, so that the number of routing paths during circuit connection can be reduced, which is convenient for the circuit layout of the camera module.

[0105] The above has introduced in detail a camera module and an electronic device disclosed in the embodiment of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the camera module and the electronic device of the present invention and its core idea. At the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
