Background technique

As the performance requirements of mobile phone camera modules increase, photosensitive chips with larger imaging sizes need to be used. In order to resolve a larger-sized photosensitive chip, the total optical length (total track length, TTL) of the lens needs to be increased, resulting in an increase in the thickness of the camera module. When the camera module is applied to a mobile phone, the height of the mobile phone at the position of the camera module is high, which hinders the thinning of the mobile phone, and the user experience of the mobile phone is poor. Therefore, setting a camera module with a thinner thickness has attracted more and more attention from various research institutes and enterprises.

The driving device includes a driving mechanism, a first fitting and a second fitting. Both the first matching part and the driving mechanism are fixedly connected to the module circuit board. The first fitting is connected to the driving mechanism. The second fitting is movably connected to the first fitting.

The lens assembly includes a lens motor and a first lens. The lens motor is fixedly connected to the second fitting. The first lens is arranged on the lens motor and opposite to the photosensitive chip. The lens motor is used to drive the first lens to move along the optical axis of the camera module.

When the camera module switches from the working state to the non-working state, the driving mechanism drives the first matching part to move, the second matching part is close to the module circuit board, and the lens motor and the first lens are close to the photosensitive chip.

In this embodiment, the camera module is provided with a driving device, so that when the camera module switches from the working state to the stop state, the driving mechanism can drive the first matching part to move, and the second matching part is in the position of the first matching part.

In this way, when the camera module is in a stopped state, the lens assembly and the photosensitive chip can be compactly arranged, and the distance between the lens assembly and the photosensitive chip is short, so that the thickness of the camera module is small, which is beneficial to the thinness of the camera module. settings.

In a practicable manner, the first fitting is a cylindrical structure, and the inner side of the first fitting has a thread structure. The second matching part is a cylindrical structure, and the outer side of the second matching part has a thread structure. The first fitting is threadedly connected with the second fitting. The driving mechanism is used to drive the first fitting to rotate around the optical axis of the camera module, so as to drive the second fitting to move in a direction parallel to the optical axis of the camera module. In this way, the structure of the driving device is relatively simple.

The second structural member is located inside the first structural member. The first boss is opposite to the second boss. The second boss is located on the side of the first boss away from the module circuit board. The lens motor is fixedly connected to the second boss. The buffer piece is connected between the first boss and the second boss.

It is understandable that when the camera module is accidentally dropped, the lens assembly collides with external objects. The lens assembly presses the second structural member. At this time, the buffer member can apply elastic force to the second structural member, so as to buffer the pressing force of the lens assembly on the second structural member, so as to prevent the lens assembly and the second structural member from being damaged.

In a practicable manner, the first boss is provided with a first limiting groove. The second boss is provided with a second limiting groove. A part of the buffer is arranged in the first limiting groove. A part of the buffer member is arranged in the second limiting groove. In this way, the connection area between the buffer member and the first boss and the second boss is larger, and the connection between the buffer member and the first boss and the second boss is more stable.

In a practicable manner, the buffer member is a spring, shrapnel, rubber or silicone.

In a practicable manner, the second matching part further includes a third structural part. The third structural member is ring-shaped.

The second lens includes a second lens barrel. The second lens barrel has a first limiting portion and a second limiting portion arranged at intervals.

The connection mechanism includes a first guide rod, a second guide rod, a first limit bracket and a second limit bracket. At least part of the first limiting bracket is located on a side of the first limiting portion away from the first lens. At least part of the second limiting bracket is located on a side of the second limiting portion away from the first lens.

The first lens is close to the second lens, and the second lens is in a static state.

It can be understood that, by adding the second lens, the number of lenses is increased, thereby increasing the total optical length of the camera module, which is beneficial to the high-quality imaging of the camera module. In addition, by connecting the connecting mechanism between the first lens and the second lens, when the camera module is in a stop state (also called a non-working state), the first lens and the second lens can be arranged in a compact manner, and the first lens The distance between the second lens and the second lens is short, the second lens can be arranged compactly with the photosensitive chip, and the distance between the second lens and the photosensitive chip is short, so that the thickness of the camera module is small, which is beneficial to the camera module.

The second end of the first guide rod is fixedly connected to the second part. The first magnet is located between the first part of the first limiting bracket and the middle part of the first guide rod, and the material of the first limiting bracket is a magnetically permeable material.

It can be understood that, since the first limiting bracket is a magnetically permeable material, the first part of the first limiting bracket and the first magnet can generate magnetic force. The direction of the magnetic force received by the first magnet is the direction in which the first part of the first limiting bracket faces the first magnet. The first limiting part is also pressed by the first magnet, and at this time, the first guide rod can closely fit with the first limiting part under the extrusion of the first limiting part.

In a practicable manner, the first limiting portion is provided with a third guide hole. The first guide rod passes through the third guide hole and is slidably connected to the third guide hole. The third guide hole is a V-shaped hole. The middle part of the third guide hole is facing the first magnet.

Since the second structural member 4632 is elastically connected to the first structural member 4631 through the buffer member 4634, and the third structural member 4633 is fixedly connected to the first structural member 4631, at this time, the second structural member 4632 and the third structural member 4633 can also be The first structure member 4631 moves along the Z-axis direction.

Please refer to FIG. 34 and FIG. 35 again, as shown in FIG. 30 , when the camera module 40 is shifted from the stop position to the middle position, the driving mechanism 46 a drives the first matching member 462 to rotate. Since the first structural member 4631 of the second fitting 463 is screwed to the first fitting 462, and the first fitting 462 is fixedly connected to the module bracket 44, the first structural member 4631 of the second fitting 463 can be opposite to the first The matching part 462 moves along the positive direction of the Z axis. Since the second structural member 4632 of the second matching member 463 is elastically connected to the first structural member 4631 of the second matching member 463 , the second structural member 4632 can move along the positive direction of the Z-axis along with the first structural member 4631 . Since the base 4711 of the lens motor 471 (shown in conjunction with FIG. 26 ) is fixedly connected to the second structural member 4632 of the second fitting 463, the first lens 472 is fixedly connected to the mobile bracket 4714 (shown in conjunction with FIG. 26 ), and the lens motor 471 And the first lens 472 can move along the positive direction of the Z axis along with the second structural member 4632 . Because the first fixed portion 4741a of the first guide rod 4741 is fixedly connected to the movable bracket 4714 of the first lens 472, the second fixed portion 4742a of the second guide rod 4742 is fixedly connected to the movable bracket 4714, and the second fixed portion 4742a of the first limiting bracket 4745 The second part 4745b is fixedly connected to the second end of the first guide part 4741b of the first guide rod 4741, and the second part 4745b of the second limit bracket 4746 is fixedly connected to the second end of the second guide part 4742b of the second guide rod 4742. end, the first guide rod 4741 , the second guide rod 4742 , the first limit bracket 4745 and the second limit bracket 4746 move along the Z-axis direction with the moving bracket 4714 . When the camera module 40 is in the middle position, the second part 4745b of the first limiting bracket 4745 moves to contact with the first limiting part 4732 of the second lens barrel 473a of the second lens 473, and the second part 4746 of the second limiting bracket 4746 The second portion 4745b moves to contact with the second limiting portion 4733 of the second barrel 473a of the second lens 473 .

In addition, because the first annular wall 4761 of the cover plate fixing frame 476 is fixedly connected to the second structural member 4632 of the second matching member 463, the second annular wall 4762 of the cover plate fixing frame 476 is fixedly connected to the first sealing ring 48a, and the lens The cover plate 477 is fixedly connected to the bottom wall 4763 of the cover plate fixing frame 476. At this time, the cover plate fixing frame 476, the first sealing ring 48a and the lens cover plate 477 all move along the positive direction of the Z axis.

It can be understood that when the camera module 40 switches from the stop position to the middle position, the relative position between the second lens 473 and the photosensitive chip 43 does not move, that is, the second lens 473 is in a static state, and the first lens 472 Relative to the photosensitive chip 43 moving along the positive direction of the Z axis, at this time, the distance between the second lens 473 and the first lens 472 increases. Similarly, when the camera module 40 is converted from the intermediate position to the stop position, the relative position between the second lens 473 and the photosensitive chip 43 does not move, and the first lens 472 moves relative to the photosensitive chip 43 along the negative direction of the Z axis. At this time, the distance between the second lens 473 and the first lens 472 decreases.

Please refer to FIG. 35 and FIG. 36 , and in combination with FIG. 30 , when the camera module 40 is shifted from the middle position to the start position, the driving mechanism 46a continues to drive the first fitting 462 to rotate. Both the first structural member 4631 and the second structural member 4632 of the second matching member 463 can continue to move along the positive direction of the Z axis, and the lens motor 471 (shown in conjunction with FIG. 26 ) and the first lens 472 can also continue to move with the second The structural member 4632 moves along the positive direction of the Z axis. The first guide rod 4741 , the second guide rod 4742 , the first limit bracket 4745 and the second limit bracket 4746 continue to move along the positive direction of the Z-axis along with the moving bracket 4714 . Since the second portion 4745b of the first limiting bracket 4745 is in contact with the first limiting portion 4732 of the second barrel 473a of the second lens 473, the second portion 4745b of the second limiting bracket 4746 is in contact with the first limiting portion 4732 of the second lens 473. The second limiting portion 4733 of the second lens barrel 473a contacts, and the first limiting bracket 4745 and the second limiting bracket 4746 can pull the second lens 473 to move along the positive direction of the Z axis.

It can be understood that when the camera module 40 shifts from the middle position to the starting position, the second lens 473 moves relative to the photosensitive chip 43 along the positive direction of the Z axis, and the distance between the second lens 473 and the photosensitive chip 43 increases. In addition, since both the first lens 472 and the second lens 473 move along the positive direction of the Z axis, the relative position between the first lens 472 and the second lens 473 does not change. Similarly, when the camera module 40 is converted from the starting position to the middle position, the second lens 473 moves relative to the photosensitive chip 43 along the negative direction of the Z axis, and the distance between the second lens 473 and the photosensitive chip 43 decreases. In addition, since both the first lens 472 and the second lens 473 move along the negative direction of the Z axis, the relative position between the first lens 472 and the second lens 473 does not change.
