[0002] Common handheld optical products in the prior art, such as digital cameras, video cameras, and mobile phones, utilize optical systems composed of an optical lens module and a camera driver module. In addition to focusing, camera driver modules are susceptible to external forces that can cause shaking during focusing or photographing. These factors, such as shaking caused by handholding, vehicle movement, or environmental factors, can lead to unclear or blurred images. Therefore, camera driver modules often also incorporate an anti-shake function. Due to their integration of multiple functions, the structure of camera driver modules is relatively complex, requiring the assembly of numerous components.

[0045] The present application will be further described below with reference to the accompanying drawings and implementation methods.

[0046] The present embodiment provides a camera device 10 comprising a lens module 1, a focus drive module 2, and an anti-shake drive module 3. The lens module 1, focus drive module 2, and anti-shake drive module 3 are sequentially arranged along the optical axis and fixed together in a unified structure. See Figures 1 to 5. The focus drive module 2 comprises a first housing 201, a lens barrel 202, a focus drive assembly 203, and a focus guide assembly 204. The lens barrel 202 is housed within the first housing 201 and fixed to the lens module 1. The focus drive assembly 203 is connected to the first housing 201 and the lens barrel 202, respectively, and is used to drive the lens barrel 202 to move relative to the first housing 201. The focus drive assembly 203 includes a focus magnet 2031 and a focus coil 2032, respectively. The focus magnet 2031 is fixed to the first housing 201. The focus coil 2032 is fixed to the lens barrel 202. The focus guide assembly 204 is confined between the first housing 201 and the lens barrel 202 and is used to guide the lens barrel 202 to move along the optical axis of the lens module 1. The anti-shake drive module 3 includes a second housing 301, a bracket 302, an image sensor 303, an anti-shake drive assembly 304, and an anti-shake guide assembly 305. The bracket 302 is housed in the second housing 301 and is fixed to the image sensor 303. The anti-shake drive assembly 304 is connected to the second housing 301 and the bracket 302, respectively, and is used to drive the bracket 302 to move relative to the second housing 301. The anti-shake guide assembly 305 is confined between the second housing 301 and the bracket 302 and is used to guide the bracket 302 to move in a direction perpendicular to the optical axis of the lens module 1.

[0047] In the embodiment of the present application, referring to Figures 6 and 12, the camera device 10 is provided with a focus guide assembly 204 that can guide the lens barrel 202 to move along the optical axis of the lens module 1, and an anti-shake guide assembly 305 that can guide the bracket 302 to move in a direction perpendicular to the optical axis of the lens module 1, thereby effectively limiting the movement direction of the lens barrel 202 and the image sensor 303, achieving anti-shake, and effectively ensuring the quality of the camera. Moreover, the lens module 1, the focus drive module 2, and the anti-shake drive module 3 are three independent modules. During assembly, each module is assembled separately, and then the three modules are assembled together, which reduces the assembly difficulty, makes assembly easier, and can effectively improve the product yield.

[0048] In this embodiment, the focus guide assembly 204 is used to guide the lens barrel 202 to move along the optical axis direction of the lens module 1 . For example, the focus guide assembly 204 guides the lens barrel 202 to move along the optical axis direction of the lens module 1 .

[0049] In this embodiment, the anti-shake guide assembly 305 is used to guide the bracket 302 to move in a direction perpendicular to the optical axis of the lens module 1. The anti-shake guide assembly 305 can guide the bracket 302 to move in a direction perpendicular to the optical axis of the lens module 1. In addition, the anti-shake guide assembly 305 can also be used to guide the bracket 302 to rotate around the optical axis in a plane perpendicular to the optical axis. In some preferred embodiments, the anti-shake drive module 3 also includes a first circuit board 306. Referring to Figures 12 and 13, the first circuit board 306 is planar, which can effectively reduce the thickness of the anti-shake drive module 3 and the camera device 10, thereby effectively reducing the volume of the camera device 10. In addition, the first circuit board 306 is partially housed in the second shell 301, and the first circuit board 306 is fixed to the side of the bracket 302 away from the lens module 1. A first mounting hole 3061 is provided in the middle of the first circuit board 306. The image sensor 303 is fixed in the first mounting hole 3061 , and the image sensor 303 and the anti-shake driving assembly 304 are electrically connected to the first circuit board 306 , respectively.

[0050] In some examples, the first circuit board 306 may be a Flexible Printed Circuit (FPC), which is easier to assemble.

[0051] In some preferred embodiments, referring to Figures 12 and 13 , the first circuit board 306 includes a first circuit board body 3062, a circuit board fixing portion 3063, and a first electrical connection portion 3064. A first mounting hole 3061 is defined in the first circuit board body 3062. The circuit board fixing portion 3063 is elastically connected to the exterior of the first circuit board body 3062. The first electrical connection portion 3064 is fixed to the circuit board fixing portion 3063. The first circuit board body 3062 and the circuit board fixing portion 3063 are housed within the second housing 301. The first circuit board body 3062 is fixed to the bracket 302, the circuit board fixing portion 3063 is fixed to the second housing 301, and the first electrical connection portion 3064 extends outside the second housing 301.

[0052] In some more preferred embodiments, the first circuit board 306 also includes a frame-shaped elastic connecting portion 3066, which is elastically connected to the first circuit board body 3062 and the circuit board fixing portion 3063 respectively, so that the first circuit board body 3062 can move in a plane perpendicular to the optical axis direction, thereby driving the image sensor 303 to move.

[0053] As an example, referring to FIG. 16 , the elastic connection portion 3066 may include two sets of first elastic edges 30661 and two sets of second elastic edges 30662. The two sets of first elastic edges 30661 are provided in correspondence with each other, each set of first elastic edges 30661 being connected to the first circuit board body 3062 via a first connecting arm 3067. The two sets of second elastic edges 30662 are provided in correspondence with each other, each set of second elastic edges 30662 being connected to the circuit board fixing portion 3063 via a second connecting arm 3068. This allows the first circuit board body 3062 to move relative to the circuit board fixing portion 3063 in a plane perpendicular to the optical axis, thereby driving the movement of the image sensor 303.

[0054] In some examples, each set of first elastic edges 30661 may include multiple parallel first elastic edges 30661, and each set of second elastic edges 30662 may include multiple parallel second elastic edges 30662, thereby ensuring the strength and restoring force of the elastic connection portion 30666. For example, referring to FIG16 , each set of first elastic edges 30661 may include two parallel first elastic edges 30661, and each set of second elastic edges 30662 may include two parallel second elastic edges 30662.

[0055] In some more preferred embodiments, please refer to Figures 12 and 13, the first circuit board 306 also has a plurality of clearance spaces 3065. All the clearance spaces 3065 are symmetrically arranged, and each clearance space 3065 is respectively formed between the first circuit board body 3062 and the circuit board fixing portion 3063. Correspondingly, please refer to Figure 15, the bracket 302 has an anti-collision boss 3021. The anti-collision boss 3021 is formed on the side of the bracket 302 facing the first circuit board 306, and the anti-collision boss 3021 is arranged in a one-to-one correspondence with the clearance space 3065. Each anti-collision boss 3021 passes through the corresponding clearance space 3065, thereby preventing the first circuit board 306 and the image sensor 303 from colliding with the second shell 301 along the optical axis, thereby effectively protecting the first circuit board 306 and the image sensor 303.

[0056] In some more preferred embodiments, please refer to Figure 15. In order to further protect the first circuit board 306 and the image sensor 303, the bracket 302 also has an anti-collision surface 3022 parallel to the optical axis. The anti-collision surface 3022 can prevent the first circuit board 306 and the image sensor 303 from colliding with the second shell 301 in a direction perpendicular to the optical axis, thereby effectively protecting the first circuit board 306 and the image sensor 303.

[0057] In this embodiment, please refer to Figure 15, the bracket 302 has an anti-collision boss 3021 and an anti-collision surface 3022, which can fully protect the first circuit board 306 and the image sensor 303, prevent the first circuit board 306 and the image sensor 303 from colliding with the second shell 301, and effectively improve the service life of the camera device 10.

[0058] In some preferred embodiments, there are multiple anti-shake guide assemblies 305. Each anti-shake guide assembly 305 is constrained between the second housing 301 and the bracket 302. Each anti-shake guide assembly 305 includes a first ball bearing 3051 and two support plates 3052 (see Figure 3). The two support plates 3052 abut against the ends of the first ball bearing 3051 along the optical axis. One support plate 3052 also abuts the second housing 301, and the other support plate 3052 also abuts the bracket 302. This effectively protects the second housing 301 and the bracket 302, preventing wear and tear after long-term use, and effectively extending the service life of the camera device 10.

[0059] In some more preferred embodiments, the bracket 302 is formed with a first limiting cylinder 3023, as shown in Figures 3 and 14. One of the support plates 3052 is disposed within the first limiting cylinder 3023, and the first ball 3051 is also received within the first limiting cylinder 3023, thereby effectively restraining the support plate 3052 and the first ball 3051. Accordingly, the second housing 301 is formed with a second limiting cylinder 30111, and another support plate 3052 is disposed within the second limiting cylinder 30111, thereby effectively restraining the support plate 3052, ensuring the structural stability of the anti-shake drive module 3 and preventing the support plate 3052 and the first ball 3051 from moving freely.

[0060] In some exemplary embodiments, the support sheet 3052 may be made of ceramic. The first rolling ball 3051 may also be made of ceramic. It is understood that in other embodiments, the support sheet 3052 and / or the first rolling ball 3051 may also be made of other materials.

[0061] In some preferred embodiments, there are multiple anti-shake drive assemblies 304. Each anti-shake drive assembly 304 is respectively connected to the second shell 301 and the bracket 302. Each anti-shake drive assembly 304 includes a corresponding anti-shake magnet 3041 and an anti-shake coil 3042, please refer to Figure 3. The anti-shake magnet 3041 is fixed to the second shell 301. The anti-shake coil 3042 is fixed to the bracket 302, and the anti-shake coil 3042 is electrically connected to the first circuit board 306. The anti-shake drive module 3 also includes an anti-shake yoke 307. The anti-shake yoke 307 is corresponding to the anti-shake drive assembly 304 and is fixed to the bracket 302. The anti-shake yoke 307 and the anti-shake magnet 3041 are magnetically attracted to each other, so that the anti-shake guide assembly 305 abuts between the bracket 302 and the second shell 301, ensuring that the bracket 302 and the second shell 301 can cooperate with each other to press the anti-shake guide assembly 305. The anti-shake magnetic yoke 307 can also provide a restoring force, so that the bracket 302 has a reset function.

[0062] In some more preferred embodiments, a first stopper 3024 is formed on the bracket 302, as shown in FIG14 . The first stopper 3024 corresponds to the anti-shake coil 3042. During assembly, the anti-shake coil 3042 can be placed over the first stopper 3024, thereby quickly and accurately positioning the anti-shake coil 3042 on the bracket 302.

[0063] As an example, each first limiting portion 3024 may include a plurality of limiting posts arranged at intervals, as shown in FIG14 . The anti-shake coil 3042 is simultaneously sleeved on all the limiting posts, thereby positioning the anti-shake coil 3042 on the bracket 302 .

[0064] It is understandable that in other embodiments, the first limiting portion 3024 may also be other structures.

[0065] In some more preferred embodiments, the anti-shake coil 3042 and the anti-shake magnetic yoke 307 can be arranged at both ends of the bracket 302 along the optical axis direction, please refer to Figures 14 and 15. This can not only ensure the effective cooperation between the anti-shake coil 3042 and the anti-shake magnetic yoke 307 and the anti-shake magnetic steel 3041, but also avoid the anti-shake magnetic yoke 307 and the anti-shake magnetic steel 3041 from being separated from the bracket 302 due to magnetic adsorption.

[0066] In some examples, referring to FIG15 , a third mounting hole 3025 can be defined on the side of the bracket 302 facing away from the anti-shake coil 3042. The third mounting hole 3025 can be used to mount the anti-shake yoke 307, thereby quickly and effectively positioning and securing the anti-shake yoke 307 on the bracket 302.

[0067] In some preferred embodiments, the anti-shake drive module 3 further includes a second circuit board 308, as shown in FIG14 . The second circuit board 308 is secured between the anti-shake coil 3042 and the bracket 302. The anti-shake coil 3042 is electrically connected to the first circuit board 306 via the second circuit board 308. The electrical connection between the anti-shake coil 3042 and the first circuit board 306, located on opposite sides of the bracket 302, via the second circuit board 308 facilitates wiring and provides a more stable electrical connection.

[0068] In some preferred embodiments, the second circuit board 308 may include a second circuit board body 3081 and a second electrical connection portion 3082, as shown in FIG14 . The second circuit board body 3081 is frame-shaped. The second electrical connection portion 3082 extends from the second circuit board body 3081 toward the first circuit board 306 . The second electrical connection portion 3082 can be used to electrically connect to the first circuit board body 3062 . This not only simplifies the structure and facilitates connection, but also ensures the stability of the electrical connection between the second circuit board 308 and the first circuit board 306 .

[0069] In some more preferred embodiments, the second circuit board body 3081 is in a flat plate shape, which can effectively reduce the thickness of the anti-shake driving module 3 and the camera device 10 , thereby effectively reducing the volume of the camera device 10 .

[0070] In some examples, the second circuit board 308 may be a Flexible Printed Circuit (FPC), which is easier to assemble.

[0071] In some preferred embodiments, the anti-shake drive module 3 further includes an anti-shake drive chip. The anti-shake drive chip can control the current of the anti-shake coil 3042. As an example, the anti-shake drive chip can be fixed to the second circuit board 308 and electrically connected to the second circuit board 308.

[0072] In this embodiment, the anti-shake magnet 3041 is fixed to the second shell 301, and the anti-shake coil 3042, the anti-shake magnetic yoke 307, and the anti-shake driving chip are all fixed to the bracket 302. That is, the anti-shake coil 3042, the anti-shake magnetic yoke 307, the anti-shake driving chip and the bracket 302 can move together.

[0073] It is understandable that, in other implementations, the anti-shake driving chip may also be fixed to the first circuit board 306 and electrically connected to the first circuit board 306 .

[0074] In some examples, the anti-shake driver chip may be AK7323.

[0075] In some preferred embodiments, there are multiple focus guide assemblies 204. Referring to Figure 10 , each focus guide assembly 204 is confined between the first housing 201 and the lens barrel 202. Each focus guide assembly 204 includes a plurality of second rolling balls 2041 sequentially arranged along the optical axis. Each second rolling ball 2041 is confined between the first housing 201 and the lens barrel 202 and can roll along the optical axis.

[0076] In some exemplary embodiments, the second ball 2041 can be made of ceramic material. In other embodiments, the second ball 2041 can also be made of other materials.

[0077] As an example, the diameters of all second balls 2041 can be equal. Alternatively, the diameters of the second balls 2041 can be unequal. For example, referring to FIG10 , each focus guide assembly 204 includes three second balls 2041 , wherein the diameters of the two second balls 2041 on either side are equal, and the diameter of the middle second ball 2041 is smaller than the diameters of the two second balls 2041 on either side. This not only prevents the middle second ball 2041 from interfering with the two second balls 2041 on either side, but also makes the overall structure more stable.

[0078] In this embodiment, the first housing 201 is provided with a first limiting groove 20121. The first limiting groove 20121 extends along the optical axis. The lens barrel 202 is provided with a second limiting groove 2021. The second limiting groove 2021 extends along the optical axis. The first limiting groove 20121, the second limiting groove 2021, and the focus guide assembly 204 are provided in a one-to-one correspondence. The corresponding first limiting groove 20121 and the second limiting groove 2021 are abutted to form a limiting channel 205. The limiting channel 205 extends along the optical axis. The focus guide assembly 204 is confined between the corresponding first limiting groove 20121 and the second limiting groove 2021. In other words, the focus guide assembly 204 is confined within the corresponding limiting channel 205 (see FIG10 ). This ensures that the focus guide assembly 204 can guide the lens barrel 202 to move along the optical axis of the lens module 1.

[0079] In some preferred embodiments, there are multiple focus driving assemblies 203. Each focus driving assembly 203 is connected to the first housing 201 and the lens barrel 202 respectively.

[0080] In some preferred embodiments, the focus drive module 2 further includes a focus yoke 206 corresponding to the focus drive assembly 203. The focus yoke 206 is fixed to the lens barrel 202. The focus yoke 206 and the focus magnet 2031 are magnetically attracted to each other, thereby causing the focus guide assembly 204 to abut between the lens barrel 202 and the first housing 201, ensuring that the lens barrel 202 and the first housing 201 can cooperate with each other to press the focus guide assembly 204. In addition, the focus yoke 206 can also provide a restoring force, allowing the lens barrel 202 to have a reset function.

[0081] In this embodiment, a second stopper 2022 is formed on the outside of the lens barrel 202 (see Figure 3 ). The second stopper 2022 corresponds to the focus coil 2032. During assembly, the focus coil 2032 can be placed over the second stopper 2022, allowing it to be quickly and accurately positioned on the lens barrel 202.

[0082] As an example, the second limiting portion 2022 may be in a strip-shaped structure as shown in FIG. 6 , or the second limiting portion 2022 may be in other structures.
