Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The following is for reference. Figures 1-13 A camera module 10 according to an embodiment of the present utility model is described.

[0046] like Figures 1-13 As shown, the camera module 10 according to an embodiment of the present invention includes: a lens module, a focusing module, and an image stabilization module.

[0047] Specifically, refer to Figures 1-13The lens module includes a lens 12 and a lens mount 13; the focusing module 1 includes a focusing bracket 11 and a first driving unit. The focusing bracket 11 has a first receiving cavity 111, and the lens mount 13 is located in the first receiving cavity 111 and is movably connected to the focusing bracket 11. The first driving unit includes a first driving member 132 and a second driving member 114. The first driving member 132 is located on the lens mount 13, and the second driving member 114 is disposed on the focusing bracket 11 corresponding to the first driving member 132. Under the action of the second driving member 114, the first driving member 132 drives the lens mount 13 relative to the focusing bracket 11 along the optical axis direction of the lens 12 (e.g., ...). Figure 1 Move along direction a) as shown to achieve focus;

[0048] The lens 12 is movably mounted in the focusing bracket 11 along the optical axis of the lens. The lens mount 13 is connected to the lens 12 and is movable relative to the focusing bracket 11 along the optical axis of the lens, thereby driving the lens 12 to move along the optical axis of the lens, thus achieving active focusing. In addition, the lens 12 and the lens mount 13 can be a single piece or separate pieces.

[0049] The image stabilization module includes a base 3, an image stabilization carrier 2, and a second drive unit. The base 3 has a second receiving cavity 33. The image stabilization carrier 2 is located in the second receiving cavity 33 and is movably connected to the base 3. The image stabilization carrier 2 has a third receiving cavity 21. The focusing bracket 11 is located in the third receiving cavity 21 and is fixedly connected to the image stabilization carrier 2. The image stabilization carrier 2 and the focusing bracket 11 are connected by AA (Active Alignment) adhesive 14. The second drive unit includes a third drive component 22 and a fourth drive component 31. The third drive component 22 is located in the image stabilization carrier 2. The fourth drive component 31 is disposed in the base 3 corresponding to the third drive component 22. Under the action of the fourth drive component 31, the third drive component 22 drives the image stabilization carrier 2 to move relative to the base 3 in a direction perpendicular to the optical axis of the lens 12 to achieve image stabilization.

[0050] It should be noted that, for example Figures 1-9 As shown, the camera module 10 also includes a housing 8 and a packaged chip 7. The packaged chip 7 is located on the side of the base 3 opposite to the image stabilization carrier 2 along the optical axis of the lens. The photosensitive element is packaged on the packaged chip 7. The base 3 has a through hole that passes through the base 3 along the optical axis of the lens for light to pass through. An installation space is formed between the housing 8 and the base 3. The image stabilization carrier 2 and the focusing bracket 11 are located in the installation space. There is a gap between the focusing bracket 11 and the side wall of the installation space opposite to the base 3 along the optical axis of the lens, which facilitates the movement of the lens 12 along the optical axis of the lens to achieve active focusing. Under normal circumstances, the gap between the focusing bracket 11 and the side wall of the installation space opposite to the base 3 along the optical axis of the lens is much larger than the focusing distance.

[0051] It is understandable that the housing 8, the base 3, and the packaged chip 7 are located inside an electronic device such as a mobile phone. Therefore, along the optical axis of the lens, the distance between the end of the packaged chip 7 away from the housing 8 and the end of the housing 8 away from the packaged chip 7 will affect the thickness of the electronic device. In the prior art, AA glue is often placed between the packaged chip and the base for the optical axis alignment of the lens and the photosensitive element. However, due to the presence of AA glue, the overall height of the packaged chip and the base is too high, resulting in a large distance between the end of the packaged chip away from the housing and the end of the housing away from the packaged chip along the optical axis of the lens, thus making the electronic device (such as a mobile phone) thicker.

[0052] In this invention, the AA adhesive 14 is located between the focusing bracket 11 and the image stabilizing carrier 2. On the one hand, the AA adhesive 14 can achieve precise positioning and fixation between the lens 12 and the image sensor, thereby achieving optical axis synchronization between the lens 12 and the image sensor. On the other hand, the arrangement of the AA adhesive 14 can utilize the focusing space of the lens 12 in the optical axis direction of the lens (since the gap between the focusing bracket 11 and the side wall of the mounting space away from the base 3 along the optical axis direction of the lens is much larger than the focusing distance, the arrangement of the AA adhesive 14 will not affect the focusing of the lens 12), thereby reducing the distance between the end of the encapsulation chip 7 away from the housing 8 and the end of the housing 8 away from the encapsulation chip 7 along the optical axis direction of the lens, making the thickness of the electronic device along the optical axis direction of the lens smaller.

[0053] In addition, the optical axis synchronization between the lens 12 and the image sensor has been achieved by fixing and positioning the focus bracket 11 and the image stabilization carrier 2 with AA glue 14. The packaged chip 7 and the base 3 can be connected by welding without the need for AA glue 14. That is, no additional structural components need to be set between the packaged chip 7 and the base 3, thereby reducing the distance between the end of the packaged chip 7 away from the housing 8 and the end of the housing 8 away from the packaged chip 7 along the optical axis of the lens.

[0054] Furthermore, both ends of the focusing bracket 11 along the optical axis of the lens are open (not shown in the figure in this embodiment). This allows the lens mount 13 to move more freely along the optical axis of the lens, thereby achieving a wider range of focusing. At the same time, it avoids interference between the space occupied by the AA glue 14 along the optical axis of the lens and the focusing space of the lens 12. When the installation space inside the housing 8 is relatively compact, the influence of the AA glue 14 on the focusing space of the lens 12 can be eliminated, thereby improving the applicability.

[0055] Or, such as Figure 12 and Figure 13As shown, the focusing bracket 11 has a first receiving cavity 111 on the side away from the image stabilization carrier 2. The lens mount 13 is disposed in the first receiving cavity 111. The bottom wall of the first receiving cavity 111 is provided with a clearance hole 112, and the lens 12 passes through the clearance hole 112. Thus, the lens mount 13 can be supported.

[0056] It should be noted that the inner peripheral wall of the focusing bracket 11 has a first sliding groove 113, and the inner peripheral wall of the lens mount 13 has a second sliding groove 131 that cooperates with the first sliding groove 113. The first sliding groove 113 and the second sliding groove 131 extend along the optical axis of the lens. A fourth rolling element 15 is provided in the first sliding groove 113 and the second sliding groove 131. The fourth rolling element 15 is movably disposed in the first sliding groove 113 and the second sliding groove 131 along the optical axis of the lens. As a result, the sliding friction of the lens mount 13 relative to the focusing bracket 11 when moving in the optical axis of the lens is converted into rolling friction, thereby reducing the frictional force when the lens mount 13 and the focusing bracket 11 move relative to each other, making the movement of the lens mount 13 smoother. At the same time, it also prevents the lens mount 13 and the focusing bracket 11 from moving in the second and third directions.

[0057] Furthermore, such as Figure 12 and Figure 13 As shown, there are multiple first sliding grooves 113, and multiple fourth rolling elements 15 and second sliding grooves 131 corresponding one-to-one with the multiple first sliding grooves 113, thereby making the mirror mount 13 move more smoothly. For example, in Figure 12 and Figure 13 In the example shown, there are two of each of the first slide groove 113, the second slide groove 131, and the fourth rolling element 15. However, the present invention is not limited to this. There can be more than one of each of the first slide groove 113, the second slide groove 131, and the fourth rolling element 15, such as three, four, five, or six.

[0058] At the same time, such as Figure 13 As shown, the focusing bracket 11 has a second driving member 114 on its peripheral wall, and the lens mount 13 has a first driving member 132 on its peripheral wall. The lens mount 13 is driven to move in the optical axis direction of the lens by the second driving member 114 and the first driving member 132.

[0059] According to an embodiment of the present invention, the camera module 10 includes a lens module comprising a lens 12 and a lens mount 13, and a focusing module 1 comprising a focusing bracket 11 and a first driving unit. The focusing bracket 11 has a first receiving cavity 111, and the lens mount 13 is located in the first receiving cavity 111. The first driving unit includes a first driving member 132 and a second driving member 114. The first driving member 132 is located on the lens mount 13, and the second driving member 114 is disposed on the focusing bracket 11 corresponding to the first driving member 132. Under the action of the second driving member 114, the first driving member 132 drives the lens mount 13 to move relative to the focusing bracket 11 along the optical axis of the lens 12 to achieve focusing. Image stabilization is also included. The module includes a base 3, an image stabilization carrier 2, and a second drive unit. The base 3 has a second receiving cavity 33. The image stabilization carrier 2 is located in the second receiving cavity 33 and is movably connected to the base 3. The image stabilization carrier 2 has a third receiving cavity 21. The focusing bracket 11 is located in the third receiving cavity 21. The image stabilization carrier 2 and the focusing bracket 11 are connected by AA glue 14, so that the arrangement of AA glue 14 can utilize the space for focusing of the lens 12 in the optical axis direction of the lens, thereby reducing the distance between the end of the encapsulation chip 7 away from the housing 8 and the end of the housing 8 away from the encapsulation chip 7 in the optical axis direction of the lens, making the thickness of the electronic device in the optical axis direction of the lens smaller.

[0060] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the focusing module 1 also includes a lens mount 13, which is sleeved on the outside of the lens 12 and connected to the lens 12. The lens mount 13 is movable relative to the focusing bracket 11 in the optical axis direction of the lens.

[0061] In some embodiments of this utility model, such as Figure 7 As shown, the image stabilization module also includes a first rolling element 51. The base 3 is provided with a first rolling groove (the side of the base 3 facing the image stabilization carrier 2 has a first rolling groove). The image stabilization carrier 2 is provided with a second rolling groove corresponding to the first rolling groove (the second rolling groove is provided at the end of the image stabilization carrier 2 facing the base 3). The first rolling element 51 is movably disposed in at least one of the first rolling groove and the second rolling groove in a direction perpendicular to the optical axis of the lens 12.

[0062] For example, in this utility model, the first rolling element 51 is along a third direction (such as...). Figure 1 (as shown in direction c) and the second direction (as shown in direction c) Figure 1 The first rolling element 51 is movably disposed in the second rolling groove and the first rolling groove (as shown in direction b), wherein the second direction, the third direction, and the optical axis direction of the lens are mutually perpendicular. However, the present invention is not limited to this; the first rolling element 51 may also be movably disposed in the second rolling groove along the third direction and the second direction, or the first rolling element 51 may also be movably disposed in the first rolling groove along the third direction and the second direction.

[0063] It is understood that the first rolling element 51 is disposed in at least one of the second rolling groove and the first rolling groove in a direction perpendicular to the optical axis of the lens 12. On the one hand, the groove wall of the second rolling groove and / or the first rolling groove can limit the first rolling element 51, thereby limiting the rolling range of the first rolling element 51, thereby limiting the range of movement of the image stabilization carrier 2, and avoiding damage caused by the image stabilization carrier 2 impacting the housing 8 and other structures when it moves.

[0064] On the other hand, the first rolling element 51 enables the image stabilization carrier 2 to move in a plane perpendicular to the optical axis of the lens, thereby reducing the number of layers of the rolling element 5 and further reducing the height of the camera module 10 in the optical axis of the lens.

[0065] In some embodiments of this invention, the diameter of the first rolling element 51 is smaller than the dimension of at least one of the second rolling groove and the first rolling groove in any direction within the projection onto a plane perpendicular to the optical axis of the lens. This enables the first rolling element 51 to be movable in a second direction and a third direction.

[0066] For example, in this invention, the outer contours of the projections of the second rolling groove and the first rolling groove onto a plane perpendicular to the optical axis of the lens can both be circular, and the diameters of the second rolling groove and the first rolling groove are both greater than the diameter of the first rolling element 51.

[0067] Furthermore, there are multiple second rolling grooves, and the first rolling element 51 and the first rolling groove are multiple corresponding to the multiple second rolling grooves, thereby making the movement of the anti-shake carrier 2 more stable and smooth.

[0068] In some embodiments of this utility model, such as Figures 1-6 As shown, the rolling element 5, including the camera module 10, further includes: a rolling element guide bracket 4, a second rolling element 52, and a third rolling element 53. In the optical axis direction of the lens, the rolling element guide bracket 4 is disposed between the base 3 and the image stabilization carrier 2. The second rolling element 52 is movably disposed between the rolling element guide bracket 4 and the base 3, allowing the rolling element guide bracket 4 to move relative to the base 3. The third rolling element 53 is movably disposed between the rolling element guide bracket 4 and the image stabilization carrier 2, allowing the image stabilization carrier 2 to move relative to the rolling element guide bracket 4. One of the second rolling element 52 and the third rolling element 53 is movable along a second direction, and the other is movable along a third direction. The second direction, the third direction, and the optical axis direction of the lens are perpendicular to each other. Thus, the image stabilization carrier 2 is movable relative to the base 3 in the second and third directions, thereby achieving the image stabilization function.

[0069] The following description illustrates the movable nature of the anti-shake carrier 2 relative to the base 3 in the second and third directions, using the second rolling element 52 being movable in the second direction and the third rolling element 53 being movable in the third direction as an example:

[0070] When the anti-shake carrier 2 moves along the second direction, the second rolling element 52 moves along the second direction, thereby causing the anti-shake carrier 2 to drive the rolling element guide bracket 4 to move relative to the base 3 along the second direction. When the anti-shake carrier 2 moves along the third direction, the third rolling element 53 moves along the third direction, thereby causing the anti-shake carrier 2 to move relative to the rolling element guide bracket 4 along the third direction. At this time, the rolling element guide bracket 4 is stationary relative to the base 3, thereby realizing the movement of the anti-shake carrier 2 relative to the base 3 along the third direction.

[0071] In some embodiments of this utility model, such as Figures 1-6 As shown, the anti-shake carrier 2 has a first groove on the side facing the rolling element guide bracket 4, the base 3 has a second groove on the side facing the rolling element guide bracket 4, the rolling element guide bracket 4 has a third groove on the side facing the anti-shake carrier 2, and the rolling element guide bracket 4 has a fourth groove on the side facing the base 3. At least one of the first groove and the third groove extends along a second direction, and at least one of the second groove and the fourth groove extends along a third direction. The second rolling element 52 is disposed in the second groove and the fourth groove, and the third rolling element 53 is disposed in the first groove and the third groove.

[0072] For example, in this utility model, the first groove and the third groove both extend along the second direction, and the second groove and the fourth groove both extend along the third direction. However, this utility model is not limited to this. It is also possible that the first groove extends along the second direction, or the third groove extends along the second direction; the second groove extends along the third direction, or the fourth groove extends along the third direction.

[0073] It is understandable that the first and third grooves allow the third rolling element 53 to move in the second direction, thereby enabling the anti-shake carrier 2 to move relative to the rolling element guide bracket 4 in the second direction. The second and fourth grooves prevent the second rolling element 52 from moving in the second direction, thereby preventing the rolling element guide bracket 4 and the base 3 from moving in the second direction. Therefore, when the anti-shake carrier 2 moves relative to the rolling element guide bracket 4 in the second direction, the rolling element guide bracket 4 and the base 3 are prevented from moving in the second direction, that is, the rolling element guide bracket 4 and the base 3 are stationary at this time, thereby enabling the anti-shake carrier 2 to move relative to the base 3 in the second direction.

[0074] Similarly, the second and fourth grooves allow the second rolling element 52 to move upwards in a third direction, thereby enabling the rolling element guide bracket 4 to move upwards in a third direction relative to the base 3. The first and third grooves prevent the third rolling element 53 from moving upwards in a third direction, thus preventing the anti-shake carrier 2 from moving upwards in a third direction relative to the rolling element guide bracket 4. Therefore, when the rolling element guide bracket 4 moves upwards in a third direction relative to the base 3, the anti-shake carrier 2 and the rolling element guide bracket 4 remain relatively stationary, thereby enabling the anti-shake carrier 2 to move in a third direction relative to the base 3.

[0075] Meanwhile, the arrangement of the first, second, third, and fourth slots can also prevent relative rotation between the axis extending around the optical axis of the lens between the rolling element guide bracket 4, the base 3, and the image stabilization carrier 2.

[0076] In some embodiments of this utility model, such as Figure 7 and Figure 11 As shown, the camera module 10 also includes an elastic component 6, which is disposed between the base 3 and the image stabilization carrier 2 along the optical axis of the lens. The image stabilization carrier 2 and the base 3 are floatingly connected in a direction perpendicular to the optical axis of the lens via the elastic component 6. It should be noted that the floating connection between the image stabilization carrier 2 and the base 3 in a direction perpendicular to the optical axis of the lens via the elastic component 6 means that the image stabilization carrier 2 and the base 3 are connected, and the image stabilization carrier 2 can make small displacements relative to the base 3 in the first direction, the second direction, and the third direction.

[0077] Understandably, in its initial position, the elastic component 6 has no elastic stress. At this time, the axis of the base 3 and the axis of the image stabilization carrier 2 coincide. When the image stabilization carrier 2 enters the image stabilization state, it moves in a direction perpendicular to the optical axis of the lens, generating elastic stress on the elastic component 6. When the image stabilization function is completed, the elastic component 6 returns to its initial state, thereby driving the image stabilization carrier 2 to automatically return to its original position, achieving the coincidence of the axis of the base 3 and the axis of the image stabilization carrier 2, ensuring synchronization between the photosensitive element and the optical axis of the lens 12. Furthermore, when the image stabilization carrier 2 rotates relative to the base 3 around the optical axis of the lens, the elastic component 6 can also achieve the return of the image stabilization carrier 2 to its original position.

[0078] In some embodiments of this utility model, such as Figure 7 and Figure 11 As shown, the elastic component 6 includes: a first fixing member 61, a second fixing member 62, and an elastic member 63. The first fixing member 61 is fixedly connected to the image stabilization carrier 2. There are multiple second fixing members 62, which are located on the side of the first fixing member 61 away from the axis of the camera module 10. The multiple second fixing members 62 are evenly arranged along the circumferential direction of the base 3 and are fixedly connected to the base 3. Each second fixing member 62 and the first fixing member 61 are connected by the elastic member 63.

[0079] Understandably, when the image stabilization carrier 2 enters the image stabilization state, it moves in a plane perpendicular to the optical axis of the lens, driving the first fixing member 61 to move in the same plane. This, in turn, drives the corresponding elastic member 63 to stretch or compress in the same direction. When the image stabilization function is complete, the elastic member 63 drives the first fixing member 61 back to its initial position, thereby driving the image stabilization carrier 2 back to its initial position. This achieves automatic repositioning of the image stabilization carrier 2, ensuring that the axis of the base 3 and the axis of the image stabilization carrier 2 are aligned, thus guaranteeing synchronization between the optical axis of the image sensor and the lens 12.

[0080] For example in Figure 11 In the example shown, there are 4 second fasteners 62, but the present invention is not limited to this. The number of second fasteners 62 can also be other numbers, such as 3, 5, 6 or 7.

[0081] In some embodiments of this utility model, such as Figure 1 , Figure 7 and Figure 13 As shown, the first driving unit and the second driving unit are electromagnetically driven; wherein, as Figure 13 As shown, one of the first driving member 132 and the second driving member 114 is a first magnet and the other is a first coil; thus, through electromagnetic drive, the lens module is driven in the optical axis direction of the lens, thereby achieving focusing of the lens module.

[0082] Furthermore, such as Figure 1 and Figure 7 As shown, one of the third driving component 22 and the fourth driving component 31 is a second magnet, and the other is a second coil. The image stabilization carrier 2 is connected to the focusing bracket 11, so that when the image stabilization carrier 2 moves in a direction perpendicular to the optical axis of the lens, it can drive the focusing bracket 11 to move, thereby realizing the image stabilization function.

[0083] It is understood that the second drive unit consists of two groups, each group of which includes a third drive member 22 and a fourth drive member 31. One of the two groups of second drive units is used to drive the image stabilization carrier 2 to move along the second direction, and the other is used to drive the image stabilization carrier 2 to move along the third direction.

[0084] In some embodiments of this utility model, such as Figure 1 and Figure 7 As shown, one side of the third receiving cavity 21 is open along the second direction, and / or one side of the third receiving cavity 21 is open along the third direction, with the second direction, the third direction, and the optical axis direction of the lens being mutually perpendicular. This avoids installation interference with the lens module and facilitates lens module installation.

[0085] The following describes an electronic device according to an embodiment of the present invention.

[0086] The electronic device according to an embodiment of the present invention includes the camera module 10 described above.

[0087] According to the electronic device of this utility model embodiment, by setting the above-mentioned camera module 10, the lens module includes a lens 12 and a lens mount 13, the focusing module 1 includes a focusing bracket 11 and a first driving part, the focusing bracket 11 is provided with a first receiving cavity 111, the lens mount 13 is located in the first receiving cavity 111, the first driving part includes a first driving member 132 and a second driving member 114, the first driving member 132 is located in the lens mount 13, and the second driving member 114 is disposed on the focusing bracket 11 corresponding to the first driving member 132. Under the action of the second driving member 114, the first driving member 132 drives the lens mount 13 to move relative to the focusing bracket 11 along the optical axis direction of the lens 12 to achieve The focusing and image stabilization module includes a base 3, an image stabilization carrier 2, and a second drive unit. The base 3 has a second receiving cavity 33. The image stabilization carrier 2 is located in the second receiving cavity 33 and is movably connected to the base 3. The image stabilization carrier 2 has a third receiving cavity 21. The focusing bracket 11 is located in the third receiving cavity 21. The image stabilization carrier 2 and the focusing bracket 11 are connected by AA glue 14, so that the arrangement of AA glue 14 can utilize the space for focusing of the lens 12 in the optical axis direction of the lens, thereby reducing the distance between the end of the encapsulation chip 7 away from the housing 8 and the end of the housing 8 away from the encapsulation chip 7 in the optical axis direction of the lens, making the thickness of the electronic device in the optical axis direction of the lens smaller.
