Description

Camera devices and electronic equipment

[0001] This application is based on and claims the priority of Japanese patent application No. 2023-120809, filed on July 25, 2023. The entire contents of the Japanese patent application are hereby incorporated into this application by reference. Technical Field

[0002] The present application relates to the technical field of camera focusing, and in particular to a camera and an electronic device. Background Art

[0003] With the rapid development of photography technology, drive mechanisms for lens movement have become widely used in various camera devices, including various mobile devices. Common camera drive mechanisms typically move the lens along the optical axis or in a plane perpendicular to the optical axis. These drive mechanisms typically consist of a drive coil and a magnet. The drive coil is fixed to the outer periphery of the lens frame. When the drive coil is energized to generate a magnetic field, the electromagnetic force causes the lens within the lens frame to move along the optical axis to achieve focusing, move along a plane perpendicular to the optical axis, or oscillate around the lens' principal point to achieve image stabilization.

[0004] This type of drive mechanism is typically equipped with leaf springs to elastically support and suspend the lens frame, keeping it in contact with other components. This allows the lens to move linearly when electromagnetic force is applied to the lens frame. However, this elastic support and suspension structure resonates during vibration mode, and suppressing the degradation in control performance during focusing caused by this resonance is a key issue in lens design. Furthermore, in the upper and lower leaf spring designs used to control lens tilt, the width of the leaf springs affects the weight distribution of the lens, making the design and manufacturing of the entire lens more difficult.

[0005] Therefore, it is necessary to provide a camera device and an electronic device to solve the above problems. Technical Solutions

[0006] The purpose of some embodiments of the present application is to provide a camera device and an electronic device to solve the problem of reduced control performance caused by leaf spring resonance and weight distribution caused by leaf spring width in the above-mentioned driving mechanism with leaf springs.

[0007] An embodiment of the present application provides a camera device, comprising a driving mechanism and a lens module having an optical axis; the driving mechanism comprises a base and a first frame rotatably arranged on the base, the base is provided with a first magnetic yoke and a driving coil, the first frame is provided with a magnet and has an inclined support surface inclined relative to the optical axis, the first magnetic yoke and the magnet are arranged opposite to each other in the direction of the optical axis, the magnet exerts an attractive force on the first magnetic yoke along the direction of the optical axis to press the first frame onto the base; the lens module comprises a lens holder pressed on the first frame, the first frame supports the lens holder via the inclined support surface; after the driving coil is energized to generate a magnetic field, the first frame is driven to rotate in a plane perpendicular to the optical axis direction via the magnet, and the first frame drives the lens holder to move along the optical axis direction or tilt relative to the optical axis via the rotating inclined support surface.

[0008] An embodiment of the present application also provides an electronic device, including a device body and the camera device as described above.

[0009] Compared with the prior art, the embodiment of the present application sets a first frame with an inclined support surface on the base, and uses the inclined support surface of the first frame to support the lens holder. When the driving coil on the base drives the first frame to rotate, it causes the inclined support surface to move relative to the lens holder, thereby causing the lens holder located on the inclined support surface to change its position relative to the optical axis. In this way, the lens holder can drive the lens to move along the optical axis or tilt relative to the optical axis, and then realize the focusing function by the movement of the lens in the direction of the optical axis, and realize the anti-shake correction function by the tilting of the lens relative to the optical axis. This structural design uses the inclined support surface to realize the focusing and anti-shake functions without the need for additional leaf springs, avoiding the problem of reduced control performance caused by leaf spring resonance and the weight distribution problem caused by the width of the leaf spring.

[0010] In addition, there are a plurality of first frames, and the plurality of first frames are arranged on the base at approximately equal intervals along a direction surrounding the optical axis.

[0011] In addition, there are four first frames, and the four first frames are arranged opposite to each other in pairs. Two of the first frames arranged opposite to each other drive the lens holder to move in opposite directions along the optical axis via the rotating inclined supporting surfaces, so that the lens holder rotates around a first direction perpendicular to the optical axis; the other two first frames arranged opposite to each other drive the lens holder to move in opposite directions along the optical axis via the rotating inclined supporting surfaces, so that the lens holder rotates around a second direction perpendicular to the optical axis and the first direction; the four first frames rotate simultaneously to superimpose the rotation of the lens holder in the first direction and the second direction, so that the lens holder tilts relative to the optical axis.

[0012] In addition, the plurality of first frames all drive the lens holder to move in the same direction along the optical axis via the rotating inclined support surface, so that the lens holder moves along the optical axis. In some embodiments, the base is provided with a plurality of rotation shafts corresponding one to one with the plurality of first frames, and each first frame is provided with a rotation shaft hole, and the rotation shaft is inserted into the corresponding rotation shaft hole to rotatably mount the corresponding first frame on the base.

[0013] In addition, the height of the inclined support surface increases gradually in a direction surrounding the corresponding rotation axis.

[0014] In addition, the height of the inclined support surface increases in a clockwise direction around the corresponding rotation axis.

[0015] In addition, the height change trend and height change amplitude of each inclined support surface in the direction around the corresponding rotation axis are the same.

[0016] In addition, projections of the driving coil and the first frame along the optical axis are intertwined with each other.

[0017] In addition, a spherical supporting protrusion is provided on the lens bracket, and the inclined supporting surface abuts against the spherical supporting protrusion on the lens bracket to support the lens bracket via the spherical supporting protrusion on the lens bracket.

[0018] In addition, a spherical supporting protrusion is provided on the first frame, and the base abuts against the spherical supporting protrusion on the first frame to support the first frame via the spherical supporting protrusion on the first frame.

[0019] In addition, a position detection element is provided on the base to detect the rotation amount of the first frame.

[0020] In addition, the lens module includes a lens and a second magnetic yoke fixed on the lens holder, the second magnetic yoke is arranged opposite to the magnet in the optical axis direction, and the magnet exerts an attractive force on the second magnetic yoke along the optical axis direction to press the lens holder on the first frame.

[0021] In addition, spherical protrusions are provided on the object side and image side of the lens holder, and the first frame is provided with a groove that contacts the spherical protrusion and accommodates the spherical protrusion. The first frame applies force to the spherical protrusion of the lens holder through the groove to press the lens holder on the first frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, some embodiments of this application are further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0036] The first embodiment of the present application relates to a camera device 100, as shown in Figures 1 to 6, including: a driving mechanism 10 and a lens module 20 having an optical axis OO', the driving mechanism 10 includes a base 12 and a first frame 11 rotatably arranged on the base 12, a first magnetic yoke 13 and a driving coil 14 are provided on the base 12, a magnet 15 is provided on the first frame 11 and has an inclined support surface 112 inclined relative to the orthogonal surface 222 of the optical axis OO', the first magnetic yoke 13 and the position of the magnet 15 on the first frame 11 when no external force is applied (in the direction of the optical axis OO'), the magnet 15 exerts an attractive force on the first magnetic yoke 13 along the direction of the optical axis OO' to press the first frame 11 against the base. 12; the lens module 20 includes a lens holder 21, a lens 22 fixed on the lens holder 21 and a second magnetic yoke 23, the second magnetic yoke 23 and the magnet 15 are arranged opposite to each other in the direction of the optical axis OO', the magnet 15 exerts an attractive force on the second magnetic yoke 23 along the direction of the optical axis OO' to press the lens holder 21 on the first frame 11, and the first frame 11 supports the lens holder 21 via the inclined support surface 112; after the driving coil 14 is energized to generate a magnetic field, the first frame 11 is driven to rotate in a plane perpendicular to the direction of the optical axis OO' via the magnet 15, and the first frame 11 drives the lens holder 21 to move along the direction of the optical axis OO' or tilt relative to the optical axis OO' via the rotating inclined support surface 112.

[0037] Compared with the prior art, the embodiment of the present application is characterized in that a 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 holder 21. When the driving coil 14 on the base 12 drives the first frame 11 to rotate, the inclined support surface 112 will cause the movement of the lens holder 21, thereby causing the position of the lens holder 21 located on the inclined support surface 112 to change relative to the optical axis OO'. In this way, the lens holder 21 can drive the lens 22 to move along the optical axis OO' direction or tilt relative to the optical axis OO', thereby achieving the focusing function through the movement of the lens 22 in the direction of the optical axis OO', and achieving the anti-shake correction function through the tilting of the lens 22 relative to the optical axis OO'. This structural design uses the inclined support surface 112 to achieve the focusing and anti-shake functions without the need for an additional leaf spring, thereby avoiding the problem of reduced control performance caused by the resonance of the leaf spring and the weight distribution problem caused by the width of the leaf spring.

[0038] Specifically, the driving mechanism 10 includes a first frame 11 , a base 12 for supporting the first frame 11 , a first magnetic yoke 13 and a driving coil 14 provided on the base 12 , a magnet 15 provided on the first frame 11 , and a rotating shaft 16 protruding from the base 12 .

[0039] The first magnetic yoke 13 is disposed on the base 12 and is positioned opposite the magnet 15 in the direction of the optical axis OO'. The first magnetic yoke 13 is attracted by the magnet 15 along the optical axis OO', thereby pressing the first frame 11 against the base 12 and fixing the first frame 11. The projections of the drive coil 14 and the first frame 11 along the optical axis OO' are intertwined.

[0040] There are four first frames 11, and the four first frames 11 are arranged on the base 12 at equal intervals along the direction around the optical axis OO', and are opposite to each other. It can be understood that in some embodiments, the first frames 11 are arranged on the base 12 at approximately equal intervals along the direction around the optical axis OO'. Each first frame 11 is provided with a rotation axis hole 110 and an inclined support surface 112 inclined relative to the orthogonal surface 222 of the optical axis OO'. Correspondingly, there are also four rotation axes 16 on the base 12, and the rotation axis holes 110 on each first frame 11 correspond one-to-one to the four rotation axes 16, so that each rotation axis 16 is inserted into the corresponding rotation axis hole 110 to rotatably fix the corresponding first frame 11 on the base 12. In this way, each first frame 11 can rotate clockwise and counterclockwise around the corresponding rotation axis 16. Furthermore, in one 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 distance between the inclined support surface 112 and the plane of the base 12) increases in a clockwise direction about the corresponding rotation axis 16. It should be noted that the aforementioned design is only one feasible way to rotatably secure the first frame 11 to the base 12. In other embodiments, the rotatable arrangement of the first frame 11 can also be achieved through different structural design schemes. For example, the first frame 11 can also be provided with a protruding shaft, and the base 12 can be provided with a rotation slot / hole corresponding to the protruding shaft, so that the first frame 11 is rotatably secured to the base 12 by the protruding shaft extending into the rotation slot / hole on the base 12. It will be understood that for those skilled in the art, there are many other ways to rotatably secure the first frame 11 to the base 12, which will not be detailed here.

[0041] The lens module 20 includes a housing 200 having a receiving space, a lens holder 21 disposed within the receiving space, a lens 22 secured to the lens holder 21, and a second yoke 23. The second yoke 23 is positioned opposite the magnet 15 along the optical axis OO'. The magnet 15 exerts an attractive force on the second yoke 23 along the optical axis OO', thereby pressing the lens holder 21 against the first frame 11. The first frame 11 supports the lens holder 21 via an inclined support surface 112. It is understood that, in an alternative embodiment, the lens holder 21 can be secured using a non-yoke method. For example, as shown in Figures 7 and 8, spherical protrusions 210 can be provided on two surfaces (the object side and the image side) of the lens holder 21, and grooves 116 can be provided on the first frame 11 to contact and accommodate the spherical protrusions 210. This eliminates the need for the second yoke 23, and instead applies force to the lens holder 21 based on the position of the first frame 11. The inclined support surface is disposed within the groove 116. It is also understandable that the fixation of the above-mentioned lens bracket 21 can also be achieved by using elastic elements such as leaf springs. Specifically, the elastic element arranged between the lens bracket 21 and the base 12 is used to press the lens bracket 21 toward the first frame 11 and the base 12 along the optical axis OO'.

[0042] Furthermore, in one embodiment, a support protrusion 212 is provided on the lens bracket 21 , and the inclined support surface 112 abuts against the support protrusion 212 on the lens bracket 21 to support the lens bracket 21 via the support protrusion 212 on the lens bracket 21 .

[0043] When the driving coil 14 is energized to generate a magnetic field, the driving coil 14 drives the first frame 11 to rotate in a plane perpendicular to the optical axis OO' through the magnetic field force applied to the magnet 15. The first frame 11 applies force to the supporting protrusion 212 through the rotating inclined supporting surface 112, thereby driving the lens holder 21 to move along the optical axis OO' or tilt relative to the optical axis OO'.

[0044] Specifically, since the height of the inclined support surface 112 increases in the clockwise direction around the corresponding rotation axis 16, when each first frame 11 rotates in the clockwise or counterclockwise direction around the corresponding rotation axis 16 at the same time, the lens holder 21 can be pushed toward the image side or the object side along the optical axis OO' direction via the rotating inclined support surface 112, thereby driving the lens 22 to move in the optical axis OO' direction through the lens holder 21.

[0045] In addition, by controlling the number of the rotating first frames 11 and their rotation direction, the first frame 11 can push the lens holder 21 toward the image side along the optical axis OO' in some positions and push the lens holder 21 toward the object side along the optical axis OO' in some positions, thereby driving the lens 22 to tilt relative to the optical axis OO' through the lens holder 21.

[0046] Please refer to Figure 6 again. When the relative first frames 11 rotate in opposite directions, they can drive the lens holder 21 to rotate about different axes in a plane perpendicular to the optical axis OO'. For example, when the first frame 11 in the upper left corner of the figure is driven to rotate clockwise and the first frame 11 in the lower right corner of the figure is driven to rotate counterclockwise, the first frame 11 in the lower right corner will push the lens holder 21 toward the outside of the paper (i.e., the object side) at that location due to the increase in the height of the inclined support surface 112. The first frame 11 in the upper left corner will move the lens holder 21 toward the inside of the paper (i.e., the image side) at that location due to the decrease in the height of the inclined support surface 112. In this way, the lens holder 21 can be rotated about the X-axis (the X-axis is perpendicular to the optical axis OO') shown in Figure 6. Similarly, when the first frame 11 at the lower left corner of FIG. 6 is driven to rotate clockwise and the first frame 11 at the upper right corner is driven to rotate counterclockwise, the first frame 11 at the upper right corner will be pushed toward the outside of the paper (i.e., the object side) at this location due to the increase in the height of the inclined support surface 112. The first frame 11 at the lower left corner will be pushed toward the inside of the paper (i.e., the image side) at this location due to the decrease in the height of the inclined support surface 112. In this way, the lens holder 21 can be rotated about the Y-axis (the Y-axis is perpendicular to the X-axis and perpendicular to the optical axis OO') shown in FIG. In other words, when the two opposing first frames 11 are driven to rotate in different directions, the lens 22 can be driven to rotate about the X-axis or the Y-axis via the lens holder 21. When all four first frames 11 are driven to rotate simultaneously, the rotation of the lens holder 21 in the first direction and the rotation in the second direction can be superimposed, thereby achieving tilting of the lens holder 21 at any angle and orientation relative to the optical axis OO'.

[0047] In this way, the rotation of each first frame 11 can push the lens holder 21 to different heights or angles. By simultaneously driving multiple or relative driving coils 14, the lens holder 21 can drive the lens 22 to achieve the focusing function in the direction of the optical axis OO' and tilt relative to the optical axis OO' to achieve the anti-shake correction function.

[0048] In this camera device 100, because the lens holder 21 is supported and fixed by the first frame 11 instead of a leaf spring, the physical support structure of the lens holder 21 is strengthened without adding a large number of components, thereby reducing the impact of the camera device 100 falling. Furthermore, the camera device 100 does not need to consider leaf spring resonance during focusing and anti-shake. Instead, the rotation angle of the first frame 11 is controlled based on the height design parameters of the inclined support surface, so that the lens holder 21 drives the lens 22 to adjust the focus and swing around the lens principal point 220, thereby simplifying the control method. Furthermore, because the lens holder 21 no longer needs to be provided with a coil to drive its movement, the heat generated by the coil during electromagnetic drive is prevented from being transferred to the lens holder 21 and lens 22, causing thermal expansion. This avoids the resulting deterioration of optical properties and the noise impact on the image sensor, thereby improving camera quality and being highly adaptable to large image sensors and large lenses.

[0049] Of course, it is understandable that the height change of the inclined support surface 112 can also be designed to decrease in the clockwise direction around the corresponding rotation axis 16, so that when each first frame 11 rotates clockwise or counterclockwise around the corresponding rotation axis 16 at the same time, the lens holder 21 is pushed toward the object side or image side along the optical axis OO' direction (the movement direction of the lens holder 21 is opposite to the aforementioned method), which can also achieve the focusing function along the optical axis OO' direction and the anti-shake correction function of the tilt relative to the optical axis OO'.

[0050] It is understood that since each first frame 11 rotates independently, the height change trend and / or height change amplitude of each first frame 11 in the direction around the corresponding rotation axis 16 can be the same or different. Simply by individually controlling each first frame 11 to ensure that the height change of the inclined support surface 112 of each first frame 11 after rotation is controllable, different focusing and / or anti-shake functions can be achieved. Furthermore, to ensure that the height change of the inclined support surface 112 of each first frame 11 is the same after rotation through the same angle, thereby facilitating control of the movement distance of the lens 22, in one embodiment, the height change trend and height change amplitude of each inclined support surface 112 in the direction around the corresponding rotation axis 16 are the same. It is also understood that the aforementioned inclined support surface 112 can be an inclined plane with a constant slope or a curved surface with a gradually increasing height. As long as the height of the support portion supporting the lens holder 21 changes when the first frame 11 rotates around the rotation axis 16, focusing and anti-shake movement of the lens holder 21 can be achieved. In one embodiment, the inclined support surface 112 is an inclined plane for ease of manufacture.

[0051] It should be noted that, in one embodiment, the support protrusion 212 on the lens holder 21 is a spherical support protrusion. This reduces resistance between the inclined support surface 112 and the support protrusion 212 when the inclined support surface 112 applies force to the support protrusion 212, causing the two to move relative to each other, making the relative movement smoother. This facilitates precise control of the rotation angle of the first frame 11, thereby accurately controlling focus and anti-shake operations. Furthermore, the support protrusion 212 can be coated with a lubricant, such as oil or grease, to further reduce sliding resistance.

[0052] In addition, in one embodiment, the first frame 11 is also provided with a spherical protrusion 114. The base 12 abuts against the spherical protrusion 114 on the first frame 11 to support the first frame 11 via the spherical protrusion 114 on the first frame 11. This reduces the resistance between the first frame 11 and the base 12, making the relative rotation between the two smoother, and facilitating precise control of the rotation angle of the first frame 11, thereby accurately controlling focus and anti-shake operations. Of course, the spherical protrusion 114 on the first frame 11 can also be coated with a lubricant, such as lubricating oil or grease, to further reduce sliding resistance.

[0053] Furthermore, in order to provide precise rotation angle control for the first frame 11, in one embodiment, a position detection element 17 may be provided on the base 12. The position detection element 17 detects the rotation amount of the first frame 11 through the change in magnetic flux caused by the movement of the magnet 15, thereby providing a basis for the rotation angle control of the first frame 11 and facilitating vibration control. The number of position detection elements 17 may be at least three, or more. In addition, in one embodiment, a flexible circuit board 18 is further included, and the drive coil 14 and the position detection element 17 are both provided on the flexible circuit board 18 to obtain electrical control signals, perform electromagnetic drive and position detection via the flexible circuit board 18.

[0054] In addition, in order to reduce the vibration and impact caused by the relative movement between the first frame 11 and the base 12, in one embodiment, a shock-absorbing gel 19 can be sandwiched between the base 12 and the first frame 11 to have a shock-absorbing effect on the ripple movement when the camera device 100 is suddenly powered on, thereby facilitating more precise control of the camera device 100 to achieve an anti-shake function.

[0055] It is understood that although the number of first frames 11 is four in the aforementioned embodiment, in other embodiments, as long as the movement of the lens 22 in the direction of the optical axis OO' and the tilt relative to the optical axis OO' can be achieved through the rotation of the first frames 11, the number of first frames 11 can be three, or five, six, seven, or more. Accordingly, in order to enable each first frame 11 to rotate relatively independently, the number of rotation shafts 16 on the base 12 can also be three, five, six, seven, or more, so that each corresponds to the first frame 11 and the corresponding first frame 11 is rotatably fixed to the base 12 through the rotation shaft hole 110 on each first frame 11.

This camera system uses an inclined support surface to achieve focusing and anti-shake functions without the need for additional leaf springs, thereby avoiding the problem of reduced control performance caused by leaf spring resonance and the weight distribution problem caused by leaf spring width.
