Description

Technical Field

[0001] This utility model relates to the field of microelectronics, and in particular to a suspension wire anti-shake motor and electronic device. Background Technology

[0002] A capacitive motor utilizes a capacitor formed by a transmitting and receiving plate within the motor. Changes in the signal detected by the capacitor provide feedback on the movement of the lens within the motor. To improve detection accuracy, two receiving plates can be used, employing a differential signal method to reduce the influence of environmental factors on the detection results.

[0003] However, for suspension wire image stabilization motors, since the motor needs to detect movement in both the shaking and focusing directions, and the electrode plate located on the internal first mover cannot be directly connected to the circuit board, suspension wires are required for this connection. The number of suspension wires in a suspension wire image stabilization motor is limited, while the number of components requiring connection to the circuit board far exceeds the number of suspension wires. Therefore, it is impossible to guarantee the detection accuracy of movement in all directions using differential signal detection methods, and thus, the detection accuracy in all directions cannot be guaranteed. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a suspension wire anti-shake motor and electronic device. By setting the transmitting electrode plate on the circuit board, and forming a multi-directional detection capacitor with the second electrode plate through a third electrode plate that does not require electrical connection, a differential capacitor detection structure is formed in each direction of the detection capacitor, which ensures the detection accuracy of the detection results in all directions.

The transmitter electrode, through the focus-direction floating electrode and the two focus-direction receiver electrodes, forms a second differential capacitor detection structure, which is used to detect the movement distance of the first mover in the focus direction.

[0008] Furthermore, the jitter direction includes the X-axis direction and the Y-axis direction; the jitter direction floating electrode includes the X-axis floating electrode and the Y-axis floating electrode; the jitter direction receiving electrode includes the X-axis receiving electrode and the Y-axis receiving electrode, and the number of the X-axis receiving electrode and the Y-axis receiving electrode is at least two; the transmitting electrode, through the X-axis floating electrode and the two X-axis receiving electrodes, forms an X-axis differential capacitance detection structure, which is used to detect the movement distance of the second mover in the X-axis direction; the transmitting electrode, through the Y-axis floating electrode and the two Y-axis receiving electrodes, forms a Y-axis differential capacitance detection structure, which is used to detect the movement distance of the first mover in the Y-axis direction.

However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable readers to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0027] The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this utility model. The various embodiments can be combined with or referenced by each other without contradiction.

[0028] Embodiments of this utility model relate to a suspension wire anti-shake motor, such as... Figure 1As shown, the suspension wire image stabilization motor includes: a first mover 11, a second mover 12, an emitting electrode 21, a second electrode, a third electrode, a circuit board 3, a focus drive coil, and suspension wires 5, of which there are four suspension wires 5; the first mover 11 moves relative to the second mover 12 in the focus direction, and the second mover 12 moves in the shake direction; the third electrode includes: a shake direction floating electrode 231 and a focus direction floating electrode 232; the second electrode includes: a shake direction receiving electrode 221 and a focus direction receiving electrode 222; the number of shake direction receiving electrode 221 and focus direction receiving electrode 222 are both at least two; the emitting electrode 21 and the shake direction receiving electrode 221 are disposed on the circuit board 3, and the two focus direction receiving electrodes 222 are respectively connected by two Suspension wire 5 is connected to circuit board 3; the focusing drive coil includes a current inflow end and a current outflow end, which are respectively connected to circuit board 3 through two suspension wires 5; the two focusing direction receiving plates 222, the current inflow end and the current outflow end are all connected to different suspension wires 5; the emitting plate 21, with the help of the shaking direction floating plate 231, forms a first differential capacitor detection structure with the two shaking direction receiving plates 221, which is used to detect the movement distance of the second mover 12 in the shaking direction; the emitting plate 21, with the help of the focusing direction floating plate 232, forms a second differential capacitor detection structure with the two focusing direction receiving plates 222, which is used to detect the movement distance of the first mover 11 in the focusing direction.

[0029] The suspension wire image stabilization motor also includes: spring 4; spring 4 is connected to suspension wire 5, and springs connected to different suspension wires are not connected to each other; the focusing direction receiving plate 222 is connected to the spring through receiving plate connecting line 41.

[0030] Compared to existing technologies, this embodiment of the invention features a transmitter electrode and a shake-direction receiver electrode both mounted on a circuit board. Therefore, they do not require a suspension wire structure for connection to the circuit board. The third electrode is a floating electrode and does not need to be connected to the circuit board. This configuration only requires two focus-direction receiver electrodes to be electrically connected via suspension wires, while the remaining two suspension wires are used to electrically connect the focus drive coil to the circuit board, thus completing the normal circuit connection of all components in the entire image stabilization motor. The transmitter electrode, through the shake-direction floating electrode and the two shake-direction receiver electrodes, forms a first differential capacitor detection structure, which is used to detect the movement distance of the second mover in the shake direction. The transmitter electrode, through the focus-direction floating electrode and the two focus-direction receiver electrodes, forms a second differential capacitor detection structure, which is used to detect the movement distance of the first mover in the focus direction. This ensures that a differential capacitor detection structure is formed in the detection capacitor of each direction, guaranteeing the detection accuracy of the results in all directions.

[0031] The detection principle of the capacitance detection structure will be explained in detail below:

[0032] According to the physical principles of capacitance, the physical formula for a parallel-plate capacitor is: C = εS / 4πkd, where ε represents the dielectric constant of the medium, determined by the medium between the plates, such as air or water; k represents the electrostatic constant, also known as the Coulomb constant, which indicates that the magnitude of the force between two point charges, each with a charge of 1C, when separated by 1m in a vacuum is F = 8.987551 × 10⁻⁶. 9 N, i.e., k = 8.987551 × 10 9 N·m 2 / C; S represents the overlapping area (projected area) of the two plates; d represents the vertical distance between the two plates. As can be seen from the formula, for two capacitor plates, changing the overlapping area and the distance between the plates can change the capacitance. For two fixed plates, changing the dielectric constant of the dielectric material between the plates can also cause a change in capacitance. In this embodiment, the capacitance is changed by altering the overlapping area of ​​the plates.

[0033] The first differential capacitor detection structure is used to detect the distance the second mover 12 moves in the jitter direction, such as Figure 2 The diagram shows the arrangement of the electrode plates in the jitter direction, which includes the X-axis and Y-axis directions. The floating electrode plates in the jitter direction include an X-axis floating electrode plate 2311 and a Y-axis floating electrode plate 2312. The receiving electrode plates in the jitter direction include an X-axis receiving electrode plate 2211 and a Y-axis receiving electrode plate 2212, with at least two of each. The transmitting electrode plate 21, through the X-axis floating electrode plate 2311 and the two X-axis receiving electrodes 2211, forms an X-axis differential capacitance detection structure, which is used to detect the movement distance of the second mover in the X-axis direction. The transmitting electrode plate 21, through the Y-axis floating electrode plate 2312 and the two Y-axis receiving electrodes 2212, forms a Y-axis differential capacitance detection structure, which is used to detect the movement distance of the first mover in the Y-axis direction.

[0034] Specifically, the third electrode plate also includes: a floating electrode plate emitter 233, which is arranged opposite to the emitter electrode plate 21 to form a capacitor C3. The floating electrode plate emitter 233, the X-axis floating electrode plate 2311 and the Y-axis floating electrode plate 2312 are connected by a floating electrode plate connecting line 230, which can be a sheet metal part or a wire.

[0035] The X-axis floating electrode 2311 and the two X-axis receiving electrodes 2211 respectively form capacitor C1 X and C2 X The equivalent capacitances formed by the transmitting electrode 21 and the two X-axis receiving electrodes 2211 via the third electrode are C3 × C1. X / (C3+C1 X) and C3×C2 X / (C3+C2 X The X-axis differential capacitance is: [C3 × C1] X / (C3+C1 X )]-[C3×C2 X / (C3+C2 X )).

[0036] The Y-axis floating electrode 2312 and the two Y-axis receiving electrodes 2212 respectively form capacitor C1. Y and C2 Y The equivalent capacitances formed by the transmitting plate 21 and the two Y-axis receiving plates 2212 via the third plate are C3 × C1. Y / (C3+C1 Y ) and C3×C2 Y / (C3+C2 Y The Y-axis differential capacitance is: [C3×C1] Y / (C3+C1 Y )]-[C3×C2 Y / (C3+C2 Y )).

[0037] like Figure 2 As shown, assuming the motor is in its initial state, the distance between the upper edge of the floating electrode emitter 233 in the Y-axis direction and the upper edge of the emitter plate 21 is a1, the distance between the lower edge of the floating electrode emitter 233 in the Y-axis direction and the lower edge of the emitter plate 21 is a3, the distance between the right edge of the floating electrode emitter 233 in the X-axis direction and the right edge of the emitter plate 21 is a2, and the distance between the left edge of the floating electrode emitter 233 in the X-axis direction and the left edge of the emitter plate 21 is a4. If the range of movement of the second mover in the jitter direction is -L to L, and the initial state of the motor is 0, it is necessary to set a1, a2, a3, and a4 to be greater than L to ensure that when the second mover moves in the jitter direction (X-axis and Y-axis), the facing area of ​​the floating electrode emitter 233 and the emitter plate 21 remains unchanged, and the transmission signals of the X-axis differential capacitor detection structure and the Y-axis differential capacitor detection structure remain unchanged, thereby improving detection accuracy.

[0038] In the initial state of the motor, the distance between the upper edge of the X-axis floating electrode plate 2311 in the Y-axis direction and the upper edge of the X-axis receiving electrode plate 2211 is b1; the distance between the lower edge of the X-axis floating electrode plate 2311 in the Y-axis direction and the lower edge of the X-axis receiving electrode plate 2211 is b3; the distance between the right edge of the X-axis floating electrode plate 2311 in the X-axis direction and the right edge of one of the X-axis receiving electrode plates 2211 is b2; and the distance between the left edge of the X-axis floating electrode plate 2311 in the X-axis direction and the left edge of the other X-axis receiving electrode plate 2211 is b4. The distance between the upper edge of the Y-axis floating electrode 2312 and the upper edge of one of the Y-axis receiving electrodes 2212 is c1; the distance between the lower edge of the Y-axis floating electrode 2312 and the lower edge of the other Y-axis receiving electrode 2212 is c3; the distance between the right edge of the Y-axis floating electrode 2312 and the right edge of the Y-axis receiving electrode 2212 is c2; and the distance between the left edge of the Y-axis floating electrode 2312 and the left edge of the Y-axis receiving electrode 2212 is c2. If the second mover moves within a range of -L to L in the jitter direction, and the initial state of the motor is 0, then b1, b2, b3, b4, c1, c2, c3, and c4 all need to be greater than L. This ensures that when the second mover moves in the X-axis direction, the facing areas of the Y-axis floating plate 2312 and the two Y-axis receiving plates 2212 in the Y-axis differential capacitor detection structure remain unchanged, and the movement in the X-axis will not cause crosstalk to the Y-axis detection results. Similarly, when the second mover moves in the Y-axis direction, the facing areas of the X-axis floating plate 2311 and the two X-axis receiving plates 2211 remain unchanged, and the movement in the Y-axis will not cause crosstalk to the X-axis detection results.

[0039] The second differential capacitor detection structure is used to detect the movement distance of the first mover 11 in the focusing direction, such as Figure 3 The diagram shows the structure of each electrode plate in the focusing direction. The floating electrode plate emitter 233 and emitter electrode plate 21 are positioned opposite each other to form capacitor C3. The floating electrode plate emitter 233 and emitter electrode plate 21 can be shared with the shaking direction to save on the number of electrodes. The floating electrode plate emitter 233 and the focusing direction floating electrode plate 232 are connected by a floating electrode plate connecting line 230, which can be a sheet metal part or a wire. The emitter electrode plate 21, with the help of the focusing direction floating electrode plate 232 and two focusing direction receiving electrodes 222, forms a second differential capacitor detection structure. This second differential capacitor detection structure is used to detect the movement distance of the first mover in the focusing direction.

[0040] The floating electrode 232 in the focusing direction and the two receiving electrodes 222 in the two focusing directions respectively form capacitor C1 AF and C2 AF The equivalent capacitances formed by the emitting electrode 21, the floating electrode 232 in the focusing direction, and the two receiving electrodes 222 in the two focusing directions are respectively: C3 × C1AF / (C3+C1 AF ) and C3×C2 AF / (C3+C2 AF The second differential capacitor is: [C3×C1] AF / (C3+C1 AF )]-[C3×C2 AF / (C3+C2 AF )).

[0041] like Figure 3 As shown, assuming the motor is in its initial state, the distance between the upper edge of the focusing direction floating electrode 232 in the Z-axis direction and the upper edge of the focusing direction receiving electrode 222 above the Z-axis is d1, and the distance between the lower edge of the focusing direction floating electrode 232 in the Z-axis direction and the lower edge of the focusing direction receiving electrode 222 below the Z-axis is d2. If the range of movement of the first mover in the focusing direction is -M to M, and the initial state of the motor is 0, it is necessary to set d1 and d2 to be greater than M. This ensures that when the first mover moves within its range, the facing areas of the focusing direction floating electrode 232 and the two focusing direction receiving electrodes 222 will change with the movement, and different moving distances correspond to different facing areas. This ensures that the capacitance corresponds one-to-one with the moving distance, thus determining the uniqueness of the detection result.

[0042] The X-axis floating electrode plate, Y-axis floating electrode plate, and focusing direction floating electrode plate are integrally formed. The X-axis floating electrode plate, Y-axis floating electrode plate, and focusing direction floating electrode plate are embedded in the first mover.

[0043] Furthermore, the two focusing direction receiving plates form a rectangular pattern, and the two focusing direction receiving plates are spaced apart. The focusing direction receiving plates are L-shaped, trapezoidal, or triangular. For example... Figure 4 As shown, the focusing direction receiving electrode 222 is L-shaped. Because of this L-shape, the exposed portion of the electrode 222 contains a very narrow metal component. Widening this component would reduce sensitivity, and in subsequent reliability tests, the narrow metal component is prone to deformation. Therefore, the shape of the focusing direction receiving electrode 222 can be adjusted, such as... Figure 5 The focusing direction receiving electrode 222 is designed as a triangle to avoid narrow metal parts and thus prevent deformation. All of the above-mentioned shapes of the two focusing direction receiving electrodes 222 are centrally symmetrical.

[0044] In addition, such as Figures 4 to 5As shown, there are two floating electrode plates 232 in the focusing direction; both focusing direction receiving electrode plates 222 are located on the first plane, and the first plane is parallel to the focusing direction; the two floating electrode plates 232 in the focusing direction are located on opposite sides of the first plane. The two floating electrode plates 232 in the focusing direction are connected by a connector to form a U-shaped structure, or connected by a floating electrode plate connecting line 230, or formed by bending a metal plate to form a U-shaped structure, with the opposite sides of the U-shaped structure serving as the two floating electrode plates 232 in the focusing direction.

[0045] The simplified structure of the two focusing direction floating electrode 232 and the two focusing direction receiving electrode 222 is as follows: Figure 6 As shown, there are floating electrodes 232 on both sides of the focusing direction receiving electrode 222, which can provide more capacitance signals to the focusing direction receiving electrode 222. By increasing the amount of capacitance signal, the sensitivity of the capacitor is improved, and the capacitance changes more significantly under the same moving distance.

[0046] like Figure 7 The diagram shows the structure of two focusing direction receiving plates 222. Each focusing direction receiving plate 222 is connected to a sheet metal part 2221. A spring contact solder joint 2222 is provided at the end of the sheet metal part 2221, and the spring contact solder joint 2222 is welded to the spring contact to achieve electrical connection. In addition, an injection molding sheet metal cutout 2223 is provided on the sheet metal part 2221 for positioning the sheet metal part during injection molding.

[0047] In this embodiment, the electrode settings for the shaking direction and the focusing direction are as follows: Figure 8 As shown, two focusing direction receiving plates 222 are set inside the first mover. These plates are led out through sheet metal lines on both sides of the first mover and connected to two spring suspension wires, which in turn connect to the circuit board 3 of the base 6. For the third plate, it can be integrally formed. A focusing direction floating plate 232 is set at the position of the focusing direction receiving plate 222. The distance between the focusing direction receiving plate 222 and the focusing direction floating plate 232 is adjusted by sheet metal die casting. At the corresponding positions on the circuit board 3, a floating plate emitter 233, an X-axis floating plate 2311, and a Y-axis floating plate 2312 are formed by sheet metal bending. Finally, the third plate is integrally injection molded into the second mover.

[0048] A transmitting electrode plate 21, an X-axis receiving electrode plate 2211, and a Y-axis receiving electrode plate 2212 are set on the circuit board 3. Considering the actual space of the circuit board, the transmitting electrode plate 21 can be set in the middle of the circuit board, and the X-axis receiving electrode plate 2211 and the Y-axis receiving electrode plate 2212 are placed on its two sides respectively. At the same time, since the floating electrode plate corresponding to the second mover has a limited thickness in the X-axis, the facing area between the floating electrode plate and the receiving electrode plate is limited. In order to improve the capacitance sensitivity of the X-axis, four X-axis receiving electrodes are set. Two X-axis receiving electrodes form a differential detection structure, forming two sets of differential detection structures. At the same time, two X-axis floating electrodes are also set.

[0049] A drive coil 8 is also provided on the circuit board 3. The drive coil includes an X-axis drive coil, a Y-axis drive coil and a focus drive coil. The drive coils provided on the circuit board can be directly connected to the circuit board. The focus drive coils not provided on the circuit board need to be connected to the circuit board by means of a suspension wire.

[0050] Finally, the overall structure of the suspension wire anti-shake motor in this embodiment is described, such as... Figure 9 As shown, the suspension wire image stabilization motor includes: a base 6, a suspension wire 5, a circuit board 3, springs (lower spring 43 and upper spring 42), a second mover 12, a first mover 11, a housing 91, and a lens 92. The first and second movers are supported by the suspension wire; removing the suspension wire allows separation between the first and second movers and the base. The first and second movers are directly connected by the springs. The first mover can move relative to the second mover in the focusing direction through the deformation of the springs. The second mover drives the first mover to achieve relative movement relative to the base in the shake direction (X-axis and Y-axis directions). Figure 1 As shown, the circuit board also includes a driver chip 7, which is connected to each of the aforementioned plates and is used for transmitting and receiving plate signals.

[0051] This utility model embodiment also relates to an electronic device, including the above-mentioned suspension wire anti-shake motor.

[0052] Compared with related technologies, the electronic device provided in this embodiment of the present invention is equipped with the suspension anti-shake motor provided in the aforementioned embodiment. Therefore, it also has the technical effects provided in the aforementioned embodiment, which will not be elaborated here.

[0053] Those skilled in the art will understand that the above embodiments are specific embodiments for implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
