[0050] The present invention relates to a lens drive mechanism 100, which is a periscope lens drive mechanism. The lens drive mechanism 100 includes a base 1, a movable carrier 2 for mounting a first reflector 4, a lens carrier 3 for mounting a lens, and a second reflector 5. The base 1 has a front end and a rear end along a first direction, the front end being close to the location where light enters, and the rear end being close to the location where light exits. The base 1 includes a bottom plate 11, a front side plate 12, a rear side plate, a left side plate 14, and a right side plate 15. The bottom plate 11 is plate-shaped and extends along the first direction. The front side plate 12 and the rear side plate are arranged opposite to each other along the first direction and are respectively connected to the front and rear ends of the bottom plate 11 along the first direction. The left side plate 14 and the right side plate 15 are arranged opposite to each other along a second direction and are respectively connected to both sides of the bottom plate 11 along the second direction. The front side plate 12, the rear side plate, the left side plate 14, and the right side plate 15 are connected end to end to form an annular side plate. The front side plate 12 , the rear side plate, the left side plate 14 , the right side plate 15 and the bottom plate 11 are assembled to form a receiving groove 10 , which is used to receive the movable carrier 2 , the lens carrier 3 and the second reflector 5 .

[0051] It should be understood that in other embodiments, the base 1 may also be configured in other shapes, and the specific shape of the base 1 is not limited.

[0052] The accommodating groove 10 includes a front section 101, a middle section 102 and a rear section 103 that are connected in sequence along the first direction. The front side wall of the front section 101 is formed by the front side plate 12, and the rear side wall of the rear section 103 is formed by the rear side plate.

[0053] The front side plate 12 is provided with a boss 121 , which is connected to the inner side surface of the front side plate 12 or is integrally formed with the front side plate 12 . The boss 121 is basically located at the center of the front side plate 12 and has a recessed rotation groove 122 at one end away from the front side plate 12 .

[0054] The movable carrier 2 is positioned within the front section 101, with its front end facing the front side panel 12. The front end of the movable carrier 2 is also provided with a protruding fulcrum 24, which is located within and rotatable within the rotation slot 122, thereby enabling a movable connection between the movable carrier 2 and the front side panel 12 of the base 1. Specifically, due to the cooperation between the boss 121 and the fulcrum 24, the movable carrier 2 can rotate about an axis extending in the second direction, that is, the movable carrier 2 can nod. Furthermore, the movable carrier 2 can also rotate about an axis extending in the first direction, that is, the movable carrier 2 can shake.

[0055] The top surface of the movable carrier 2 is recessed to form a support surface 23 , which extends toward the middle section 102 to the rear end surface of the movable carrier 2 . The support surface 23 is an inclined surface gradually away from the middle section 102 from the bottom to the top, and is used to support the first reflector 4 .

[0056] The lens carrier 3 is mounted on the middle section 102 , and the lens carrier 3 can move along a first direction to adjust the focal length.

[0057] The second reflector 5 is fixedly mounted on the rear section 103 of the receiving groove 10. The second reflector 5 is tilted, and the distance between the second reflector 5 and the lens carrier 3 gradually increases from the bottom to the top. The first reflector 4 is also tilted, and the distance between the first reflector 4 and the lens carrier 3 also gradually increases from the bottom to the top.

[0058] Light enters the first reflector 4, is reflected by it, and then enters the lens of the lens carrier 3. After being focused by the lens, it enters the second reflector 5, which then reflects the received light back to the imaging chip. The imaging chip can be mounted on the top or bottom of the base 1. The position of the imaging chip can be changed depending on the installation method of the second reflector 5. After entering the first reflector, the light is reflected 90°. After the lens receives the light reflected by the first reflector, it is zoomed and projected to the second reflector. The light enters the second reflector, undergoes another 90° turn, ultimately achieving a 180° turn of the optical path.

[0059] Preferably, the base 1 further includes a mounting plate, which is located in the rear section 103 of the accommodating slot 10 and is inclined. The bottom surface of the mounting plate is closer to the lens carrier 3 than the top surface of the mounting plate. The second reflector 5 is mounted on the top surface of the mounting plate. Of course, in other embodiments, a mounting seat 104 can be directly disposed within the rear section 103. This mounting seat 104 has an inclined mounting surface that can also support the second reflector 5. The present invention is not limited to the embodiment in which the second reflector 5 is mounted in the rear section 103.

[0060] In existing designs, the second reflector 5 is generally not provided, and the imaging chip is directly mounted on the rear end of the lens carrier 3 to directly receive the light emitted by the lens carrier 3. However, since the imaging chip is in the form of a thin sheet and has a certain width and length, its installation on the rear end of the lens carrier 3 will cause the thickness of the entire lens drive mechanism 100 to increase in the vertical direction, that is, the thickness of the camera or mobile phone will increase, which cannot meet market demand. In contrast, the present invention utilizes the second reflector 5 to reflect the light from the lens carrier 3 again, allowing the imaging chip to be mounted on the top or bottom surface of the base 1. The imaging chip is in the form of a thin sheet, and its thickness does not occupy a large space, so it does not cause the thickness of the lens drive mechanism 100 to increase in the vertical direction. In other words, the thickness of the lens drive mechanism 100 can be reduced, which is convenient for adapting to mobile phones or miniaturized cameras.

[0061] Optionally, the lens driving mechanism 100 further includes a nodding coil 71 and a nodding magnet 21, which are mounted on the movable carrier 2 and the base 1 respectively. The nodding coil 71 can be mounted on the bottom of the movable carrier 2, while the nodding magnet 21 is mounted on the bottom plate 11 of the base 1. In a preferred embodiment, Figure 1-3 As shown, the nodding coil 71 can be installed on the bottom plate 11 of the base 1, and the nodding magnet 21 is installed on the bottom of the movable carrier 2. The nodding coil 71 and the nodding magnet 21 cooperate to drive the movable carrier 2 to nod and rotate around an axis parallel to the second direction.

[0062] Optionally, the lens drive mechanism 100 further includes a swaying coil 72 and a swaying magnet 22, which are mounted on the movable carrier 2 and the base 1, respectively. The swaying coil 72 can be mounted on the left side plate 14 and the right side plate 15 of the base 1, while the swaying magnet 22 can be mounted on both sides of the movable carrier 2 along the second direction and aligned with the swaying coil 72. In a preferred embodiment, two swaying coils 72 are mounted on the left side plate 14 and the right side plate 15 of the base 1, respectively, while two swaying magnets 22 are mounted on both sides of the movable carrier 2 along the second direction, and cooperate with the two swaying coils 72 to drive the movable carrier 2 to sway and rotate around an axis in the first direction.

[0063] In a preferred embodiment, the lens drive mechanism 100 further includes a reset member, which is comprised of two sets of springs 6 having the same shape and located on the inner side of the front side plate 12. The two sets of springs 6 are symmetrically arranged relative to the boss 121 and are located between the front end of the movable carrier 2 and the front side plate 12. The two sets of springs 6 are elastic and are respectively connected to the movable carrier 2 and the front side plate 12. The front end surface of the movable carrier 2 is provided with a protruding spring mounting portion 25. The spring mounting portion 25 is composed of two parts and is disposed on either side of the fulcrum 24 along the second direction. The two sets of springs 6 are respectively connected to the two sets of springs 6. The reed mounting portion 25 also provides a nodding space for the carrier to prevent the carrier from contacting the front side plate 12 during movement.

[0064] Of course, the two sets of springs 6 can also be connected to the left side plate 14 and the right side plate 15 and the movable carrier 2. After the movable carrier 2 is reset, the two sets of springs 6 can drive the movable carrier 2 to reset. In addition, the installation of the two sets of springs 6 on the inner side of the front side plate 12 does not increase the height of the lens driving mechanism 100, that is, it does not affect the thickness of the mobile phone.

[0065] The lens carrier 3 is installed in the middle section 102 of the accommodating groove 10 . The lens carrier 3 can move along a first direction and drive the lens to focus.

[0066] In one specific embodiment, zoom coils 73 are mounted on both sides of the lens carrier 3 along the second direction, that is, on the left and right sides of the lens carrier 3, respectively. Zoom magnets 31 are mounted on the left and right sides of the base 1, respectively. The two zoom magnets 31 correspond to the two sets of zoom coils 73 along the second direction and drive the lens carrier 3 to move along the first direction. Furthermore, compared to mounting the zoom magnets 31 on the bottom of the carrier, mounting the zoom magnets 31 on the left and right sides of the carrier does not affect the overall height of the lens drive mechanism 100, making it easier to adapt to thin and lightweight mobile phones.

[0067] As a preferred solution, the two zoom magnets 31 are respectively installed on the left and right sides of the lens carrier 3, and the two zoom coils 73 are respectively installed on the sides of the left plate 14 and the right plate 15 of the base 1. The zoom coil 73 needs to be connected to the external circuit and fixed on the base 1 without affecting the movement of the lens carrier 3.

[0068] Optionally, a zoom magnet 31 may be installed on the left or right side of the lens carrier 3, and a zoom coil 73 may be installed on the side of the left plate 14 or the right plate 15 of the base 1 and aligned with the zoom magnet 31. The two may cooperate to drive the lens carrier to move along the first direction.

[0069] In a preferred embodiment, the base 1 is provided with multiple mounting holes. Some of these mounting holes are located on the bottom plate 11 of the base 1 and are referred to as bottom mounting holes 16. These holes are formed by recessing the bottom surface of the bottom plate 11 into the front section 101 and are used to mount the nodding coil 71. Other mounting holes are located on the left and right panels 14, 15 of the base 1 and are referred to as side mounting holes 17. Another side mounting hole 17 is located near the front end of each panel, respectively. These side mounting holes 17 are formed by recessing the outer surface of the left or right panel into the front section 101 of the receiving slot 10. These two side mounting holes 17 are used to mount the two waving coils 72. Another two or one side mounting hole 17 is located between the left and right panels 14, 15 and is formed by recessing the left or right panel toward the middle section 102 of the receiving slot 10. These two or one side mounting holes 17 are used to mount the zoom coil 73. The mounting holes on the base 1 can not only reduce the space occupied by the nodding coil 71 , the shaking coil 72 and the zoom coil 73 , but also reduce the weight of the lens driving mechanism 100 , further improving the lightness of the lens driving mechanism 100 .

[0070] As a preferred embodiment, the lens drive mechanism 100 further includes a circuit board 7, which is connected to the base 1 and is electrically connected to the oscillating coil 72, the zoom coil 73, and the nodding coil 71. Specifically, the circuit board 7 includes three integrally formed parts, wherein the first part adheres to the outer side surface of the left side plate 14, the second part adheres to the bottom surface of the bottom plate 11 and is electrically connected to the nodding coil 71 in the bottom mounting hole 16, and the third part adheres to the outer side surface of the right side plate 15, and the first and second parts are electrically connected to the oscillating coil 72 and the zoom coil 73 in the side mounting hole 17, respectively. The nodding coil 71, the oscillating coil 72, and the zoom coil 73 are all arranged on the base 1 and electrically connected to the same circuit board 7, which can reduce wiring and will not affect the movement of the movable carrier 2 and the lens carrier 3.

[0071] The circuit board 7 is also provided with a sensor, which is located in the side mounting hole 17 and is used to sense the position of the movable carrier 2. Of course, another sensor can also be provided to sense the position of the lens carrier 3.

[0072] Preferably, the inner walls of the left and right panels 14 and 15 are respectively provided with a front baffle 18 and a rear baffle 19. The two front baffles 18 are aligned along the second direction and located between the front section 101 and the middle section 102 of the accommodating slot 10. The two rear baffles 19 are aligned along the second direction and located between the middle section 102 and the rear section 103 of the accommodating slot 10. The lens carrier 3 is located between the front baffles 18 and the rear baffles 19 and can move in the first direction between the front baffles 18 and the rear baffles 19. The front baffles 18 and the rear baffles 19 can limit the range of movement of the lens carrier 3.

[0073] As a preferred solution, the front and rear faces of the lens carrier 3 are respectively installed with anti-collision rubber 32, or only the front or rear face is provided with anti-collision rubber 32, to prevent the lens carrier 3 from colliding with the front baffle 18 and the rear baffle 19 to play a buffering role.

[0074] As a preferred solution, a guide groove extending along the first direction is provided on the top surface of the bottom plate 11 , and the guide groove is a first guide groove 112 and is located in the middle section 102 of the accommodating groove 10 .

[0075] The bottom surface of the lens carrier 3 is provided with a second guide groove 34, which is vertically aligned with the first guide groove 112. A roller 35 is further provided in the first guide groove 112. The roller 35 is clamped between the second guide groove 34 and the first guide groove 112, and can support the movement of the lens carrier 3 in the first direction, thereby preventing direct contact between the lens carrier 3 and the base plate 11. The roller 35 replaces static friction with rolling friction, thereby reducing the resistance of the lens carrier 3. In other embodiments, balls can be used instead of the roller 35, or the lens carrier 3 can be suspended on the base plate 11 by a suspension wire.

[0076] In one alternative, the bottom surface of the lens carrier 3 may be provided with a plurality of second guide grooves 34, and the top surface of the base plate 11 may be provided with a plurality of corresponding first guide grooves. The second guide grooves 34 may be semicircular grooves or elongated grooves. The first guide grooves 112 may be elongated grooves extending in the first direction. The first and second guide grooves are connected by a ball bearing. In other embodiments, the second guide grooves 34 may be elongated grooves extending in the second direction, and the first guide grooves may be semicircular grooves.

[0077] As a preferred solution, a magnetic part 111 is embedded in the bottom plate 11, and the magnetic part 111 is located in the middle section 102. The bottom surface of the lens carrier 3 is also installed with a metal sheet 33 that is attracted to the magnetic part 111. The magnetic part can be a magnetic strip or a coil. When the coil is energized, it is attracted to the metal sheet 33 to prevent the carrier from separating from the bottom plate 11 or shaking during use.

[0078] Housing 8 covers the outside of the annular side panels and is connected to bottom plate 11. A light-shielding hole 81 is provided on the top wall of housing 8. This light-shielding hole 81 is aligned with first reflector 4 to prevent light from entering first reflector 4. Furthermore, an imaging chip is mounted on the top wall of housing 8 above second reflector 5, allowing light reflected by second reflector 5 to enter the imaging chip.

[0079] The lens driving mechanism of the utility model has a compact structure and a small height along the vertical direction, which can reduce the thickness of the electronic device without affecting the focusing function.

[0080] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0081] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be construed as limited to the specific embodiments disclosed in the specification and claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
