Description

[Technical field]

[0001] The present invention relates to a focus technology field of an imaging device, and more particularly to an imaging device and an electronic device. [Background technology]

[0002] With the rapid development of photography technology, driving mechanisms for driving the movement of lenses are widely applied to various imaging devices, and such imaging devices are also applied to various mobile devices. The driving mechanisms of general imaging devices usually drive the lens to move in the optical axis direction or in a plane perpendicular to the optical axis. Such driving mechanisms often include a driving coil and a magnet, and the driving coil is fixed to the outer periphery of the lens frame. After the driving coil is energized to generate a magnetic field, the lens in the lens frame is moved in the optical axis direction by the action of electromagnetic force to realize the focusing function, and the lens in the lens frame is moved in a plane perpendicular to the optical axis or swung around the lens principal point to realize the image stabilization function.

[0003] Such a drive mechanism usually includes a leaf spring to elastically support and suspend the lens frame, and keeps the lens frame in a non-contact state with other components, thereby realizing a linear movement effect of the lens when an electromagnetic force is applied to the lens frame. However, such an elastic support and suspension structure generates resonance in a vibration mode, so suppressing the deterioration of control performance during focusing due to resonance is one of the important issues in lens design. In addition, in the design of the upper and lower leaf spring type for controlling the tilt of the lens, the design of the width of the leaf spring affects the weight distribution of the lens, making the design and manufacturing of the entire lens more difficult.

[0004] Therefore, there is a need to provide an imaging device and electronic device that solves the above problems. Summary of the Invention [Problem to be solved by the invention]

[0013] In some embodiments, the height change trend and the height change range of each of the inclined support surfaces in a direction surrounding the corresponding rotation axis are the same.

[0029] The following is a detailed description of the implementation of the imaging device and electronic device provided by the present invention. The following content is only for the purpose of making the implementation details easier to understand, and is not essential for implementing the present invention.

[0030] A first embodiment of the present invention relates to an imaging device 100, and as shown in FIGS. 1 to 6, this imaging device includes a drive mechanism 10 and a lens module 20 having an optical axis OO'. The drive mechanism 10 includes a base 12 and a first frame 11 rotatably provided on the base 12. A first yoke 13 and a drive coil 14 are provided on the base 12. The first frame 11 is provided with a magnet 15 and has an inclined support surface 112 that is inclined with respect to a plane orthogonal to the optical axis OO'. The first yoke 13 faces a position (in the optical axis OO' direction) of the magnet 15 in the first frame 11 when no external force is applied thereto. The magnet 15 applies an attractive force to the first yoke 13 along the optical axis OO' direction so as to press and hold the first frame 11 against the base 12. The lens module 20 includes a lens carrier 21, a lens 22 fixed to the lens carrier 21, and a second yoke 23, with the second yoke 23 and a magnet 15 arranged facing each other in the direction of the optical axis OO', and the magnet 15 exerts an attractive force on the second yoke 23 along the direction of the optical axis OO' so as to press and hold the lens carrier 21 against the first frame body 11, and the first frame body 11 supports the lens carrier 21 by means of an inclined support surface 112, and after current is passed through the drive coil 14 to generate a magnetic field, the magnet 15 drives the first frame body 11 to rotate within a plane perpendicular to the direction of the optical axis OO', and the first frame body 11 drives the lens carrier 21 by means of the inclined support surface 112 where the rotation occurs to move along the direction of the optical axis OO' or to tilt it relative to the optical axis OO'.

[0031] Compared with the prior art, in the embodiment of the present invention, the first frame 11 having an inclined support surface 112 is provided on the base 12, and the inclined support surface 112 of the first frame 11 is used to support the lens carrier 21. When the driving coil 14 in the base 12 drives the first frame 11 to rotate, the inclined support surface 112 moves relative to the lens carrier 21, which leads to the lens carrier 21 located on the inclined support surface 112 being displaced relative to the optical axis OO'. As a result, the lens carrier 21 can drive the lens 22 to move along the optical axis OO' direction or to tilt relative to the optical axis OO', thereby realizing the focusing function by the movement of the lens 22 in the optical axis OO' direction, and the image stabilization function by the tilt of the lens 22 relative to the optical axis OO'. Such a structural design realizes the focusing and image stabilization functions by utilizing the inclined support surface 112, does not require a separate leaf spring, and can avoid the problems of reduced control performance due to leaf spring resonance and weight distribution due to the leaf spring width.

[0032] Specifically, the drive mechanism 10 includes a first frame body 11, a base 12 for supporting the first frame body 11, a first yoke 13 and a drive coil 14 provided on the base 12, a magnet 15 provided on the first frame body 11, and a rotating shaft 16 protruding from the base 12.

[0033] The first yoke 13 is provided on the base 12, and is installed facing the magnet 15 in the direction of the optical axis OO' so as to be attracted along the direction of the optical axis OO' by the magnet 15, whereby the first frame body 11 is pressed and held against the base 12, thereby serving to fix the first frame body 11. The projections of the drive coil 14 and the first frame body 11 in the direction of the optical axis OO' intersect with each other.

[0034] The number of the first frames 11 is four, and the four first frames 11 are provided at equal intervals on the base 12 along a direction surrounding the optical axis OO', and two of them face each other. Each first frame 11 is provided with a rotation shaft hole 110 and an inclined support surface 112 inclined with respect to a plane orthogonal to the optical axis OO'. Correspondingly, the base 12 also has four rotation shafts 16, and the rotation shaft holes 110 in each first frame 11 correspond one-to-one to the four rotation shafts 16, and each rotation shaft 16 is drilled in the corresponding rotation shaft hole 110, thereby fixing and holding the corresponding first frame 11 to be rotatable on the base 12. As a result, each first frame 11 can rotate clockwise and counterclockwise around the corresponding rotation shaft 16. Furthermore, in one possible embodiment, the height of the inclined support surface 112 of each first frame 11 (i.e., the height of the inclined support surface 112 in the direction of the optical axis OO', in other words, the pitch between the inclined support surface 112 and the plane on which the base 12 is located) gradually increases clockwise in the direction surrounding the corresponding rotation axis 16. It should be noted that the above design manner is only one possible manner for rotatably fixing the first frame 11 to the base 12, and in other embodiments, the rotatable installation of the first frame 11 may be realized by a different structural design plan, for example, a convex shaft may be provided on the first frame 11, a rotation groove / hole may be provided on the base 12 corresponding one-to-one to the convex shaft, and the first frame 11 may be rotatably fixed and held on the base 12 by the convex shaft extending into the rotation groove / hole of the base 12. It can be understood that there are still many ways for those skilled in the art to rotatably fix and hold the first frame 11 to the base 12, which do not need to be described here repeatedly.

[0035] The lens module 20 includes a case 200 having an accommodation space, a lens carrier 21 provided in the accommodation space, and a lens 22 and a second yoke 23 fixed to the lens carrier 21. The second yoke 23 and the magnet 15 are installed facing each other in the direction of the optical axis OO', and the magnet 15 exerts an attractive force on the second yoke 23 along the direction of the optical axis OO' so as to press and hold the lens carrier 21 against the first frame 11, and the first frame 11 supports the lens carrier 21 by an inclined support surface 112. As can be understood, in one modified embodiment, the fixing of the lens carrier 21 can be realized in a non-yoke manner, for example, as shown in Figures 7 and 8, a spherical protrusion 210 is provided on both sides (object side and image side) of the lens carrier 21, and a groove 116 that contacts and accommodates the spherical protrusion 210 is provided in the first frame 11, so that the lens carrier 21 can be biased according to the position of the first frame 11 without using a second yoke 23, and the inclined support surface is provided in the groove 116. Similarly, the fixing of the lens carrier 21 can also be realized using an elastic member such as a leaf spring, specifically, the lens carrier 21 is pressed and held against the first frame 11 and the base 12 in the optical axis OO' direction by utilizing an elastic member provided between the lens carrier 21 and the base 12.

[0036] Furthermore, in one possible embodiment, the lens carrier 21 is provided with a support protrusion 212, and the inclined support surface 112 abuts against the support protrusion 212 on the lens carrier 21, thus supporting the lens carrier 21 by the support protrusion 212 on the lens carrier 21.

[0037] After current is passed through the drive coil 14 to generate a magnetic field, the drive coil 14 drives the first frame body 11 to rotate in a plane perpendicular to the optical axis OO' direction by the magnetic field force exerted by the magnet 15, and the first frame body 11 is biased against the support protrusion 212 by the inclined support surface 112 where the rotation occurs, and further drives the lens carrier 21 to move along the optical axis OO' direction or to tilt relative to the optical axis OO'.

[0038] Specifically, since the height of the inclined support surface 112 gradually increases clockwise in the direction surrounding the corresponding rotation axis 16, when each first frame body 11 simultaneously rotates clockwise or counterclockwise around the corresponding rotation axis 16, the rotated inclined support surface 112 pushes the lens carrier 21 toward the image side or object side along the optical axis OO' direction, and the lens carrier 21 can be driven to move the lens 22 in the optical axis OO' direction.

[0039] In addition, by controlling the number of rotated first frames 11 and their rotation direction, the first frame 11 can push the lens carrier 21 toward the image side along the optical axis OO' direction at some positions, and can push the lens carrier 21 toward the object side along the optical axis OO' direction at some positions, and the lens carrier 21 drives the lens 22 to tilt with respect to the optical axis OO'.

[0040] As shown in Fig. 6, when the opposing first frames 11 are driven to rotate in opposite directions, the lens carrier 21 can be rotated around different axes in a plane perpendicular to the optical axis OO'. For example, when the first frame 11 at the upper left of the figure is rotated clockwise and the first frame 11 at the lower right of the figure is driven to rotate counterclockwise, the first frame 11 at the lower right has a higher inclined support surface 112, so it pushes the lens carrier 21 toward the outside of the paper (i.e., toward the object) at this point, and the first frame 11 at the upper left has a lower inclined support surface 112, so it moves the lens carrier 21 toward the inside of the paper (i.e., toward the image) at this point. In this way, the lens carrier 21 is rotated around the X-axis (the X-axis is perpendicular to the optical axis OO') shown in Fig. 6. Similarly, when the first frame 11 at the bottom left of Fig. 6 is driven to rotate clockwise and the first frame 11 at the top right of the figure is driven to rotate counterclockwise, the first frame 11 at the top right pushes the lens carrier 21 toward the outside of the paper (i.e., toward the object side) at this location because the height of the inclined support surface 112 becomes higher, and the first frame 11 at the bottom left moves the lens carrier 21 toward the inside of the paper (i.e., toward the image side) at this location because the height of the inclined support surface 112 becomes lower. In this way, the lens carrier 21 is rotated around the Y axis (Y axis is perpendicular to the X axis and perpendicular to the optical axis OO') shown in Fig. 6. In other words, when two first frames 11 installed opposite to each other are driven to rotate in different directions, the lens 22 can be rotated around the X axis or the Y axis by the lens carrier 21. When the four first frame bodies 11 are driven simultaneously to rotate, the rotation of the lens carrier 21 in the first direction and the rotation in the second direction are overlapped, thereby enabling the lens carrier 21 to be tilted at any angle and in any direction relative to the optical axis OO'.

[0041] In this way, rotation of each first frame body 11 can push the lens carrier 21 to different heights and angles, and by simultaneously driving multiple drive coils 14 or opposing drive coils 14, the lens carrier 21 can drive the lens 22 to achieve a focusing function along the optical axis OO' direction, and can tilt relative to the optical axis OO' to achieve an image stabilization function.

[0042] In such an imaging device 100, the first frame 11 is used to support and fix the lens carrier 21, instead of a leaf spring, and the physical support structure of the lens carrier 21 is reinforced without increasing the number of parts, reducing the impact of the imaging device 100 being dropped. In addition, in the imaging device 100, there is no need to consider the resonance of the leaf spring when realizing focus and image stabilization, and the lens carrier 21 drives the lens 22 to adjust the focus and swing around the lens principal point 220 simply by controlling the rotation angle of the first frame 11 based on the height design parameter of the inclined support surface, making the control method simpler. In addition, there is no need to provide a coil in the lens carrier 21 to drive the movement, so that the heat generated in the coil during electromagnetic driving is not transferred to the lens carrier 21 and the lens 22 to cause thermal expansion, and the deterioration of optical characteristics and the noise effect on the image sensor due to this are avoided, which in turn improves the imaging quality and increases the adaptability to large image sensors and large lenses.

[0043] Of course, as can be understood, the change in height of the inclined support surface 112 may be set to taper off clockwise in the direction surrounding the corresponding rotation axis 16. In this way, when each first frame body 11 simultaneously rotates around the corresponding rotation axis 16 in a clockwise or counterclockwise direction, the lens carrier 21 is pushed along the optical axis OO' direction toward the object side or image side (the moving direction of the lens carrier 21 is opposite to the above-mentioned method), and similarly, a focusing function along the optical axis OO' direction and an image stabilization function tilting with respect to the optical axis OO' direction can be realized.

[0044] As can be understood, since the rotation of each first frame 11 is independent, the height change tendency and / or the height change width of each first frame 11 in the direction surrounding the corresponding rotation axis 16 may be the same or different, and different focus and / or image stabilization functions can be realized by controlling each first frame 11 independently and controlling the height change of the inclined support surface 112 after each first frame 11 rotates. Furthermore, in order to make the height change of the inclined support surface 112 after each first frame 11 rotates by the same angle the same, and to make it easier to control the moving distance of the lens 22, in one possible embodiment, the height change tendency and the height change width of each inclined support surface 112 in the direction surrounding the corresponding rotation axis 16 are both the same. As can be understood, the inclined support surface 112 may be an inclined plane with a constant gradient, or may be a curved surface with a gradually increasing height, and as long as the height of the support point supporting the lens carrier 21 changes when the first frame 11 rotates around the rotation axis 16, it is possible to realize the focusing and image stabilization movement of the lens carrier 21. In one possible embodiment, the inclined support surface 112 is an inclined plane, which is easy to manufacture.

[0045] In one preferred embodiment, the support protrusions 212 of the lens carrier 21 are spherical support protrusions. This reduces the resistance between the two when the inclined support surface 112 biases the support protrusions 212 to move relative to each other, making the relative movement between the two smoother, facilitating accurate control of the rotation angle of the first frame 11, and enabling accurate control of the focus and image stabilization operations. Preferably, a lubricant such as lubricating oil or grease is applied to the support protrusions 212 to further reduce the sliding resistance.

[0046] More preferably, in one possible embodiment, the first frame 11 is similarly provided with a spherical protrusion 114, and the base 12 abuts against the spherical protrusion 114 of the first frame 11 so as to support the first frame 11 by the spherical protrusion 114 of the first frame 11. This reduces the resistance between the first frame 11 and the base 12, making the relative rotation between them smoother, facilitating accurate control of the rotation angle of the first frame 11, and allowing for more accurate control of the focus and image stabilization operations. Of course, the spherical protrusion 114 on the first frame 11 can be coated with a lubricant such as lubricating oil or grease to further reduce the sliding resistance.

[0047] Furthermore, in order to provide accurate rotation angle control for the first frame 11, in one preferred embodiment, a position detection element 17 may be provided on the base 12. The position detection element 17 detects the amount of rotation of the first frame 11 by a change in magnetic flux caused by the movement of the magnet 15, providing a basis for controlling the rotation angle of the first frame 11 and facilitating vibration control. The number of position detection elements 17 may be at least three or more. Preferably, in one possible embodiment, the device further includes a flexible substrate 18, and both the driving coil 14 and the position detection element 17 are provided on the flexible substrate 18, so that an electrical control signal can be obtained through the flexible substrate 18 to perform electromagnetic driving and position detection.

[0048] In addition, in order to reduce vibrations and impacts caused by relative movement between the first frame body 11 and the base 12, in one possible embodiment, a vibration-damping gel 19 can be sandwiched between the base 12 and the first frame body 11, which provides a vibration-damping effect against ripple movements when electricity is suddenly applied to the imaging device 100, and makes it convenient to more accurately control the imaging device 100 to realize the image stabilization function.

[0049] As can be understood, in the above embodiment, the number of the first frames 11 is four, but in other embodiments, the number of the first frames 11 may be three, five, six, seven or more, as long as the movement of the lens 22 in the optical axis OO' direction and the tilt with respect to the optical axis OO' can be realized by the rotation of the first frames 11. Correspondingly, the number of the rotation shafts 16 on the base 12 may be three, five, six, seven or more, so that each first frame 11 can rotate relatively independently, and the corresponding first frame 11 is fixedly held to the base 12 in one-to-one correspondence with the first frame 11 through the rotation shaft hole 110 on each first frame 11 so as to be rotatable.

[0050] As shown in FIG. 9, the embodiment of the present invention relates to an imaging system including an image sensing unit 300 and the imaging device 100 in the above embodiment.

[0051] Compared with the prior art, by providing the imaging device 100 in the above embodiment on the object side of the image sensing unit 300, an imaging system capable of forming an image is formed, and there is no need to provide a separate leaf spring. Such an imaging system utilizes an inclined support surface to realize focus and image stabilization functions, and avoids the problems of reduced control performance due to leaf spring resonance and the weight distribution problems due to the leaf spring width.

[0052] As shown in FIG. 10, the embodiment of the present invention further relates to an imaging system including a bent optical mechanism 400 and the imaging device 100 in the above embodiment.

[0053] Compared to the prior art, by providing the imaging device 100 in the above embodiment to the bending optical mechanism 400, it is similarly possible to eliminate the need for a separate leaf spring, and to achieve focus and image stabilization functions by utilizing the inclined support surface, thereby avoiding the problems of reduced control performance due to leaf spring resonance and the weight distribution problems due to the leaf spring width.
