Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camera, in particular to a camera module and an electronic device. BACKGROUND

[0002] With the increasing requirement of the performance of the camera module of a mobile phone, a larger imaging size of a photosensitive chip needs to be used. In order to analyze the larger size of the photosensitive chip, the total track length (TTL) of the lens needs to be increased, which results in the increase of the thickness of the camera module. When the camera module is applied to the mobile phone, the height of the mobile phone at the position of the camera module is high, which hinders the thinness setting of the mobile phone, and the user experience of the mobile phone is poor. Therefore, the setting of a camera module with a thinner thickness is increasingly concerned by various research institutions and enterprises. SUMMARY

[0003] The present application provides a camera module with a thinner thickness and an electronic device.

[0004] In a first aspect, the present application provides a camera module. The camera module comprises a module circuit board, a photosensitive chip, a driving device and a lens assembly. The photosensitive chip is fixed to the module circuit board and electrically connected to the module circuit board.

[0005] The driving device comprises a driving mechanism, a first matching piece and a second matching piece. The first matching piece and the driving mechanism are fixedly connected to the module circuit board. The first matching piece is connected to the driving mechanism. The second matching piece is movably connected to the first matching piece.

[0006] The lens assembly comprises a lens motor and a first lens. The lens motor is fixedly connected to the second matching piece. The first lens is arranged opposite to the photosensitive chip. The lens motor is used to drive the first lens to move along the optical axis direction of the camera module.

[0007] When the camera module is converted from a working state to a stop state (also referred to as a non-working state), the driving mechanism drives the first matching piece to move, the second matching piece is close to the module circuit board, and the lens motor and the first lens are close to the photosensitive chip.

[0008] In the present embodiment, by arranging the driving device in the camera module, when the camera module is converted from the working state to the stop state, the driving mechanism can drive the first matching piece to move, the second matching piece is close to the module circuit board under the action of the first matching piece, and the lens motor and the first lens are close to the photosensitive chip. In this way, when the camera module is in the stop state, the lens assembly can be compactly arranged with the photosensitive chip, the distance between the lens assembly and the photosensitive chip is short, so that the thickness of the camera module is small, that is, the thinness setting of the camera module is facilitated.

[0009] In an implementation, the first cooperating member is a cylindrical structure, and the inner side of the first cooperating member has a threaded structure. The second cooperating member is a cylindrical structure, and the outer side of the second cooperating member has a threaded structure. The first cooperating member is threadedly connected with the second cooperating member. The driving mechanism is configured to drive the first cooperating member to rotate around the optical axis of the camera module, so as to drive the second cooperating member to move along a direction parallel to the optical axis of the camera module. In this way, the driving device has a relatively simple structure.

[0010] In an implementation, the second cooperating member includes a first structural member, a second structural member, and a buffer member. The first structural member is a cylindrical structure, and the outer side of the first structural member has a threaded structure. The first structural member is threadedly connected with the first cooperating member.

[0011] The inner surface of the first structural member has a first boss. The inner surface of the second structural member has a second boss. The second structural member is located at the inner side of the first structural member. The first boss and the second boss are oppositely arranged. The second boss is located at the side of the first boss away from the module circuit board. The lens motor is fixedly connected to the second boss. The buffer member is connected between the first boss and the second boss.

[0012] It can be understood that when the camera module falls accidentally, the lens assembly collides with an external object. The lens assembly presses the second structural member. At this time, the buffer member can apply an elastic force to the second structural member to buffer the pressing force of the lens assembly on the second structural member, so as to avoid damage to the lens assembly and the second structural member.

[0013] In an implementation, 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 member 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 of the buffer member with the first boss and the second boss is relatively large, and the connection of the buffer member with the first boss and the second boss is more stable.

[0014] In an implementation, the buffer member is a spring, a spring sheet, rubber, or silicone.

[0015] In an implementation, the second cooperating member further includes a third structural member. The third structural member is annular. The third structural member is fixedly connected to the side of the first structural member away from the module circuit board. The third structural member has a limiting protrusion. The second structural member is provided with a limiting side hole. The limiting protrusion is arranged in the limiting side hole, and the limiting protrusion is slidingly connected to the hole wall of the limiting side hole.

[0016] It can be understood that through the cooperation of the limiting protrusion of the third structural member and the limiting side hole of the second structural member, the rotation of the second structural member relative to the first structural member is avoided, and the second structural member has better stability.

[0017] In an implementation, the outer surface of the first engaging member has a gear portion. The output end of the driving mechanism is a gear structure. The gear portion is engaged with the output end of the driving mechanism.

[0018] In an implementation, the driving device 46 further includes a limiting member. The limiting member is annular. The limiting member is fixedly connected to the module circuit board. The inner wall of the limiting member is stepped. The inner wall of the limiting member has a limiting surface. The first engaging member is disposed on the inner side of the limiting member, and the gear portion of the first engaging member is clamped between the module circuit board and the limiting surface of the limiting member.

[0019] In an implementation, the lens assembly further includes a connecting mechanism and a second lens. The second lens is located between the first lens and the photosensitive chip. The connecting mechanism is connected between the first lens and the second lens.

[0020] The second lens includes a second lens barrel. The second lens barrel has a first limiting portion and a second limiting portion which are spaced apart.

[0021] The connecting mechanism includes a first guide rod, a second guide rod, a first limiting support, and a second limiting support. At least part of the first limiting support is located on the side of the first limiting portion away from the first lens. At least part of the second limiting support is located on the side of the second limiting portion away from the first lens.

[0022] The first end of the first guide rod is fixedly connected to the lens motor. The second end of the first guide rod passes through the first limiting portion and is fixedly connected to the first limiting support. The first guide rod is slidingly connected to the first limiting portion. The first end of the second guide rod is fixedly connected to the lens motor. The second end of the second guide rod passes through the second limiting portion and is fixedly connected to the second limiting support. The second guide rod is slidingly connected to the second limiting portion.

[0023] In the process of the camera module changing from the working state to the stop state, the camera module includes a starting position, an intermediate position, and a stop position.

[0024] When the camera module changes from the starting position to the intermediate position, the first guide rod, the first limiting support, the second guide rod, the second limiting support, and the second lens move towards the photosensitive chip along with the lens motor.

[0025] When the camera module changes from the intermediate position to the stop position, the first guide rod, the first limiting support, the second guide rod, and the second limiting support move towards the photosensitive chip along with the lens motor. The first lens moves towards the second lens, and the second lens is in a stationary state.

[0026] It can be understood that, by increasing the number of lenses by setting the second lens, the optical total length of the camera module is increased, which is beneficial to 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 stopped state (also referred to as a non-working state), the first lens can be compactly arranged with the second lens, the distance between the first lens and the second lens is short, the second lens can be compactly arranged with the photosensitive chip, the distance between the second lens and the photosensitive chip is short, so that the thickness of the camera module is small, that is, the thin type of the camera module is beneficial.

[0027] In an implementable manner, the connecting mechanism further includes a first elastic member and a second elastic member. The first elastic member is sleeved on the first guide rod. One end of the first elastic member is connected to the first end of the first guide rod, and the other end is connected to the first limiting portion. The first elastic member is in a compressed state. The second elastic member is sleeved on the second guide rod. One end of the second elastic member is connected to the first end of the second guide rod, and the other end is connected to the second limiting portion. The second elastic member is in a compressed state.

[0028] In an implementable manner, the connecting mechanism further includes a first magnet. The first magnet is fixedly connected to the first limiting portion. The first limiting support includes a first portion, a second portion and a third portion connected in sequence. The first portion and the third portion are connected on the same side of the second portion. The first portion and the second portion are in a bent shape. The second portion and the third portion are in a bent shape. The first portion and the third portion are respectively located on both sides of the first limiting portion. The second portion is located on the side of the first limiting portion close to the photosensitive chip.

[0029] The second end of the first guide rod is fixedly connected to the second portion. The first magnet is located between the first portion of the first limiting support and the middle portion of the first guide rod, and the material of the first limiting support is a magnetic conductive material.

[0030] It can be understood that, since the first limiting support is a magnetic conductive material, the first portion of the first limiting support and the first magnet can generate a magnetic force. The direction of the magnetic force acting on the first magnet is the direction in which the first portion of the first limiting support is directed towards the first magnet. The first limiting portion is also subjected to the extrusion force of the first magnet, at this time, the first guide rod can be tightly fitted with the first limiting portion under the extrusion of the first limiting portion.

[0031] In an implementable manner, the first limiting portion is provided with a third guide hole. The first guide rod passes through the third guide hole and is slidingly connected to the third guide hole. The third guide hole is a V-shaped hole. The middle portion of the third guide hole is directly opposite the first magnet.

[0032] It can be understood that, under the extrusion of the first limiting portion, the first guide rod is extruded in the middle portion of the third guide hole, so that the first guide rod can be more tightly fitted with the first limiting portion.

[0033] In an implementation, the lens motor includes a base, a fixed support, a moving support, a first coil, a second coil, a first motor magnet, and a second motor magnet. The base is fixedly connected to the second mating member. The fixed support is fixedly connected to the base. The moving support is slidingly connected to the base and the fixed support. The first lens is fixedly connected to the moving support.

[0034] One of the first coil and the first motor magnet is fixedly connected to the base, and the other is fixedly connected to the moving support. The first coil and the first motor magnet are oppositely arranged. One of the second coil and the second motor magnet is fixedly connected to the base, and the other is fixedly connected to the moving support. The second coil and the second motor magnet are oppositely arranged.

[0035] In an implementation, the lens motor further includes a first slide rod and a second slide rod. One end of the first slide rod is fixedly connected to the base, and the other end is fixedly connected to the fixed support. One end of the second slide rod is fixedly connected to the base, and the other end is fixedly connected to the fixed support. The second slide rod is spaced apart from the first slide rod. The moving support is slidingly connected to the first slide rod and the second slide rod.

[0036] It can be understood that by slidingly connecting the moving support to the first slide rod and the second slide rod, the moving stroke of the moving support can be improved.

[0037] In an implementation, the lens assembly further includes a variable aperture. The variable aperture is located on a side of the first lens away from the photosensitive chip. The variable aperture is fixedly connected to the first lens.

[0038] In an implementation, the lens assembly further includes a cover plate fixing frame and a lens cover plate. The cover plate fixing frame is fixed to the second mating member. The cover plate fixing frame surrounds the first lens. The lens cover plate is fixedly connected to the cover plate fixing frame. The lens cover plate is located on a side of the first lens away from the photosensitive chip and is oppositely arranged with the first lens.

[0039] In an implementation, the camera module further includes a lens decoration and a waterproof silica gel sleeve. The lens decoration is fixedly connected to the module circuit board. The cover plate fixing frame is located on the inner side of the lens decoration. The outer periphery of the waterproof silica gel sleeve is fixedly connected to the lens decoration. The inner periphery of the waterproof silica gel sleeve is fixedly connected to the cover plate fixing frame.

[0040] In an implementation, the camera module further includes a first sealing ring and a second sealing ring. The first sealing ring is fixedly connected to the inner periphery of the waterproof silica gel sleeve and the cover plate fixing frame. The second sealing ring is fixedly connected to the outer periphery of the waterproof silica gel sleeve and the lens decoration.

[0041] In a second aspect, the embodiments of the present application provide an electronic device. The electronic device includes a housing and a camera module as above. The camera module is arranged in the housing.

[0042] It can be understood that when the camera module is applied to the electronic device, the electronic device can be thinned. BRIEF DESCRIPTION OF DRAWINGS

[0080] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0081] ​​​​​​​​​​In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited otherwise, the term "connection" should be interpreted broadly, for example, "connection" can be detachable connection, or can be non-detachable connection, can be direct connection, or can be indirect connection through intermediate medium. Among them, "fixed connection" refers to the relative position relationship of the connection and the connection. "Rotary connection" refers to the relative rotation of the connection. "Sliding connection" refers to the relative sliding of the connection. The orientation terms mentioned in the embodiments of the present application, such as "top", "bottom", "inner", "outer" and the like, are only the direction of the drawings, therefore, the orientation terms used are for better and clearer illustration and understanding of the embodiments of the present application, and are not indicative or implied that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore, it cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.

[0082] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of an electronic device 100 provided by the embodiments of the present application. The electronic device 100 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet, or the like, which is a device with a camera function. Figure 1 The electronic device 100 of the embodiments shown is described by taking a mobile phone as an example.

[0083] Please refer to Figure 1 and Figure 2 , Figure 2 is Figure 1 the partial cross-sectional schematic diagram of the electronic device 100 at the A-A line. The electronic device 100 includes a housing 10, a screen 20, a main circuit board 30 and a camera module 40. It should be noted that Figure 1 , Figure 2 and the relevant drawings below only schematically show some components included in the electronic device 100, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 , Figure 2 and the drawings below. In addition, since the main circuit board 30 and the camera module 40 are internal structures of the electronic device 100, Figure 1The host circuit board 30 and the camera module 40 are schematically shown by dashed lines. In other embodiments, when the electronic device 100 is some other form of device, the electronic device 100 can not include the screen 20 and the host circuit board 30.

[0084] Exemplarily, the shell 10 includes a host frame 11 and a back cover 12. The back cover 12 is fixedly connected to one side of the host frame 11. The screen 20 is fixed to a side of the host frame 11 away from the back cover 12. The screen 20, the host frame 11 and the back cover 12 can collectively enclose an interior of the electronic device 100. The interior of the electronic device 100 can be used to house components of the electronic device 100, such as a battery, a receiver or a microphone, etc. The screen 20 can be used to display images, etc. The screen 20 can be a flat screen or a curved screen. The display screen of the screen 20 can be an organic light-emitting diode (OLED) display screen, or an active-matrix organic light-emitting diode (AMOLED) display screen, or a liquid crystal display (LCD), etc.

[0085] Please refer again to Figure 1 and Figure 2 The host circuit board 30 is fixed in the interior of the electronic device 100. The host circuit board 30 can be provided with a central processing unit (CPU), a graphics processing unit (GPU) or a universal flash storage (UFS) chip, etc.

[0086] In addition, the camera module 40 is arranged in the interior of the electronic device 100. The camera module 40 can be used to collect ambient light outside the electronic device 100. The camera module 40 can be a rear camera module or a front camera module. The camera module 40 is electrically connected to the host circuit board 30. In this way, the camera module 40 and the host circuit board 30 can transmit signals to each other.

[0087] Exemplarily, the back cover 12 is provided with a mounting hole 13. The mounting hole 13 penetrates through two opposite surfaces of the back cover 12. The mounting hole 13 can communicate the interior of the electronic device 100 to the exterior of the electronic device 100. Part of the camera module 40 can extend out of the electronic device 100 through the mounting hole 13. The camera module 40 can be fixedly connected to a hole wall of the mounting hole 13.

[0088] In the embodiment, the camera module 40 has two states, one is in working state, and the other is in non-working state (also referred to as stop state). The camera module 40 in working state can be the process from starting shooting to ending shooting. The camera module 40 in non-working state can be the state after ending shooting or the state before starting shooting. It can be understood that when the camera module 40 is in non-working state, the thickness of the camera module 40 in the Z-axis direction is the first thickness. When the camera module 40 is in working state, the thickness of the camera module 40 in the Z-axis direction is the second thickness. The first thickness is less than the second thickness. In this way, the embodiment can significantly reduce the thickness of the camera module 40 in the Z-axis direction by additionally adding a state of the camera module 40 (i.e., the non-working state of the camera module 40), thereby realizing the thin design of the camera module 40. Details will be described below in combination with relevant drawings on how to realize the additional state of the camera module 40 by relevant mechanical structure.

[0089] In the embodiment, when the camera module 40 is in working state, the camera module 40 has a starting position. When the camera module 40 is in the starting position, the camera module 40 can start shooting. When the camera module 40 is in non-working state, the camera module 40 has a stop position. When the camera module 40 is in the stop position, at least part of the components (part of the components or all the components) of the camera module 40 are in non-working state (for example, some movement mechanisms of the camera module 40 stop moving, etc.). In addition, when the camera module 40 is in non-working state, the camera module 40 also has an intermediate position. The intermediate position of the camera module 40 can be a position between the starting position and the stop position of the camera module 40.

[0090] Hereinafter, the structure when the camera module 40 is in the stop position will be described.

[0091] Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 1 the structural schematic diagram of the camera module 40 of the electronic device 100 shown in FIG. 1. Figure 4 is Figure 3 the partially exploded schematic diagram of the camera module 40. The camera module 40 includes a camera module body 40a and a lens decoration 40b. The lens decoration 40b is annular. The outer periphery of the lens decoration 40b is fixedly connected to the camera module body 40a. Part of the camera module body 40a is located inside the lens decoration 40b.

[0092] In combination with Figure 2As shown, the outer periphery of the lens decoration 40b is also fixedly connected to the inner side of the rear cover 12. Part of the lens decoration 40b extends outside the electronic device 100 through the mounting hole 13 of the rear cover 12. Exemplarily, by setting sealing glue between the outer periphery of the lens decoration 40b and the inner side of the rear cover 12, water or dust outside the electronic device 100 is prevented from entering the inside of the electronic device 100 through the gap between the lens decoration 40b and the rear cover 12.

[0093] Referring to Figure 5 , Figure 5 is Figure 4 a partially exploded schematic view of the camera module body 40a. The camera module body 40a includes a module circuit board 41, a module frame 42, a photosensitive chip 43, a module support 44, a filter 45, a driving device 46, a lens assembly 47, a first sealing ring 48a, a second sealing ring 48b, and a waterproof silica gel sleeve 49. The photosensitive chip 43 is also referred to as an image sensor, or a photosensitive element. The photosensitive chip 43 is used to collect ambient light and convert image information carried by the ambient light into an electrical signal.

[0094] Referring to Figure 6 , and in combination with Figure 5 shown, Figure 6 is Figure 4 a partially structural schematic view of the camera module body 40a. The module frame 42 includes a first frame portion 421 and a second frame portion 422. The second frame portion 422 is fixedly connected to the top of the first frame portion 421. Exemplarily, part of the first frame portion 421 is in a circular ring shape, and the other part is in a polygonal shape. The second frame portion 422 is in a circular ring shape.

[0095] The first frame portion 421 is provided with a ventilation hole 424. The ventilation hole 424 can communicate the inside of the module frame 42 to the outside of the module frame 42. The number of the ventilation hole 424 is one, or can be multiple. When the number of the ventilation hole 424 is multiple, the multiple ventilation holes 424 are arranged at intervals. The number of the ventilation hole 424 in the present embodiment is three. It can be understood that the ventilation hole 424 can balance the air pressure between the inside of the module frame 42 and the outside of the module frame 42.

[0096] In addition, the first frame portion 421 can be provided with a dust screen. The dust screen covers the ventilation hole 424. In this way, dust outside the module frame 42 is not easy to enter the inside of the module frame 42 through the ventilation hole 424.

[0097] Referring again to Figure 6The first frame portion 421 of the module frame 42 is fixedly connected to the module circuit board 41. The first frame portion 421 of the module frame 42 can enclose the first space 411 together with the module circuit board 41. Exemplarily, the first frame portion 421 of the module frame 42 can be fixedly connected to the module circuit board 41 by means of adhesion or the like.

[0098] In addition, the photosensitive chip 43 is fixed to the module circuit board 41 and electrically connected to the module circuit board 41. The photosensitive chip 43 is located in the first space 411. At this time, the photosensitive chip 43 and the module circuit board 41 can transmit signals to each other.

[0099] Exemplarily, the module circuit board 41 is provided with a sink 412. The photosensitive chip 43 is located in the sink 412. In this way, the camera module 40 is less likely to increase in thickness due to the mutual stacking of the photosensitive chip 43 and the module circuit board 41.

[0100] Please refer to Figure 7 and Figure 8 , Figure 7 is Figure 4 a partial structural schematic diagram of the camera module body 40a. Figure 8 is Figure 7 a partial cross-sectional schematic diagram of the partial camera module body 40a at the B-B line. The module support 44 is fixedly connected to the module circuit board 41. The module support 44 and the photosensitive chip 43 are located on the same side of the module circuit board 41. At least part of the module support 44 is located in the first space 411.

[0101] In addition, the module support 44 is provided with a light transmission hole 441. The filter 45 is fixedly connected to the module support 44 and located in the light transmission hole 441. The filter 45 is also oppositely arranged with the photosensitive chip 43. The filter 45 can be used to filter infrared light or blue light and the like of ambient light, so as to ensure that the photosensitive chip 43 has better imaging quality. In other embodiments, when the camera module 40 has other structures, the arrangement mode of the module support 44 and the filter 45 can be flexibly arranged according to requirements. In addition, in the structure of some camera modules 40, the camera module 40 can also not include the module support 44 and the filter 45.

[0102] Please refer to Figure 9 , Figure 9 is Figure 5 an exploded schematic diagram of the driving device 46. The driving device 46 includes a driving mechanism 46a and a lifting mechanism 46b. The driving mechanism 46a is used to drive the lifting mechanism 46b to work. The driving mechanism 46a has an output end 460a. When the driving mechanism 46a is powered on, the output end 460a of the driving mechanism 46a rotates. Exemplarily, the driving mechanism 46a can be a stepping motor. The output end 460a of the driving mechanism 46a is a gear.

[0103] Referring to Figure 10 , and in combination with Figure 9 shown, Figure 10 is Figure 9 shown, the lifting mechanism 46b includes a limiting member 461, a first cooperating member 462, and a second cooperating member 463.

[0104] Referring to Figure 11 , Figure 11 is Figure 10 shown, the limiting member 461 is ring-shaped. The limiting member 461 includes oppositely arranged inner and outer walls 4611 and 4612, and oppositely arranged top and bottom walls 4613 and 4614. The top and bottom walls 4613 and 4614 are connected between the inner and outer walls 4611 and 4612. The inner wall 4611 of the limiting member 461 is stepped. The inner wall 4611 of the limiting member 461 has a limiting surface 4615.

[0105] In addition, the limiting member 461 has a notch 4614. The notch 4614 penetrates the inner wall 4611 of the limiting member 461, the outer wall 4612 of the limiting member 461, and the bottom wall 4614 of the limiting member 461.

[0106] Referring again to Figure 10 , the first cooperating member 462 is an internally threaded cylinder structure, i.e., the first cooperating member 462 is a cylindrical structure, and the inner side of the first cooperating member 462 has a threaded structure. The outer surface of the first cooperating member 462 has a gear portion 4621. The gear portion 4621 is ring-shaped. In this embodiment, the threaded structure of the first cooperating member 462 is described as extending helically along the Z-axis direction. The gear portion 4621 of the first cooperating member 462 can be engaged with the output end 460a (see Figure 9 ) of the driving mechanism 46a. In this way, when the driving mechanism 46a is energized, the output end 460a (see Figure 9 ) of the driving mechanism 46a rotates, and the first cooperating member 462 also rotates.

[0107] Referring to Figure 12 , Figure 12 is Figure 10 shown, the second cooperating member 463 includes a first structural member 4631, a second structural member 4632, a third structural member 4633, and a buffer member 4634. The buffer member 4634 can be a spring, a spring piece, rubber, silicone, or other elastic components. In this embodiment, the buffer member 4634 is described as a spring. In addition, the number of buffer members 4634 can be one or more. In this embodiment, the number of buffer members 4634 is four.

[0108] Referring to Figure 13 , and in combination with Figure 12 illustrated, Figure 13 is Figure 12 illustrated in another angle. The first structural member 4631 is a threaded cylinder structure, i.e., the first structural member 4631 is a cylinder structure, and the outer side of the first structural member 4631 has a threaded structure. In the present embodiment, the threaded structure of the first structural member 4631 is described as extending spirally along the Z-axis direction.

[0109] In addition, the inner surface of the first structural member 4631 has a first boss 4631a. The number of the first boss 4631a can be one or multiple. When the number of the first boss 4631a is multiple, the multiple first bosses 4631a are arranged at intervals. In the present embodiment, the number of the first boss 4631a is two. In other embodiments, the first boss 4631a can also be arranged on the outer surface of the first structural member 4631.

[0110] Exemplarily, the first boss 4631a is provided with a first limiting slot 4631b. The number of the first limiting slot 4631b can be one or multiple. When the number of the first limiting slot 4631b is multiple, the multiple first limiting slots 4631b are arranged at intervals. In the present embodiment, two first limiting slots 4631b are arranged on each first boss 4631a. In other embodiments, the first boss 4631a can also not be provided with the first limiting slot 4631b.

[0111] Referring to Figure 14 , and in combination with Figure 12 illustrated, Figure 14 is Figure 12 illustrated in another angle. The second structural member 4632 is a ring structure. The inner surface of the second structural member 4632 has a second boss 4632a. The number of the second boss 4632a can be one or multiple. When the number of the second boss 4632a is multiple, the multiple second bosses 4632a are arranged at intervals. In the present embodiment, the number of the second boss 4632a is two, i.e., the same as the number of the first boss 4631a. The shape of the second boss 4632a can be adapted to the shape of the first boss 4631a. In other embodiments, the second boss 4632a can also be arranged on the outer surface of the second structural member 4632.

[0112] The second structure 4632 has a limiting side hole 4632b. The limiting side hole 4632b is open on the inner surface of the second structure 4632, the outer surface of the second structure 4632, and the top surface of the second structure 4632. The number of limiting side holes 4632b can be one or multiple. When the number of limiting side holes 4632b is multiple, the multiple limiting side holes 4632b are arranged at intervals. In the embodiment, the number of limiting side holes 4632b is two.

[0113] Exemplarily, the second boss 4632a is provided with a second limiting groove 4632c. The number of second limiting grooves 4632c can be one or multiple. When the number of second limiting grooves 4632c is multiple, the multiple second limiting grooves 4632c are arranged at intervals. In the embodiment, two second limiting grooves 4632c are arranged on each second boss 4632a. In other embodiments, the second boss 4632a can also be provided with no second limiting groove 4632c.

[0114] Please refer to Figure 15 , and in combination with Figure 13 and Figure 14 shown in Figure 15 , it is Figure 10 part of the schematic diagram of the structure of the second fitting 463 shown in FIG. 4B. The second structure 4632 is arranged on the inner side of the first structure 4631. The second boss 4632a of the second structure 4632 is arranged opposite to the first boss 4631a of the first structure 4631. The multiple first limiting grooves 4631b and the multiple second limiting grooves 4632c are arranged opposite to each other in one-to-one correspondence. At this time, one first limiting groove 4631b and one second limiting groove 4632c are arranged opposite to each other.

[0115] In addition, one end of the buffer 4634 is connected to the first boss 4631a of the first structure 4631, and the other end is connected to the second boss 4632a of the second structure 4632. In this way, the second structure 4632 is elastically connected to the first structure 4631 through the buffer 4634.

[0116] Please refer to Figure 16 , and in combination with Figure 14 shown in Figure 16 , it is Figure 10 part of the schematic diagram of the structure of the second fitting 463 shown in FIG. 4B. A part of the buffer 4634 is arranged in the first limiting groove 4631b of the first boss 4631a. A part of the buffer 4634 is arranged in the second limiting groove 4632c of the second boss 4632a. In this way, the connection area of the buffer 4634 with the first boss 4631a and the second boss 4632a is larger, and the connection of the buffer 4634 with the first boss 4631a and the second boss 4632a is more stable.

[0117] Exemplarily, the buffer 4634 can be in a compressed state. In this way, the buffer 4634 can exert an elastic force on the second structural member 4632 along the Z-axis direction.

[0118] Please refer to Figure 12 , the third structural member 4633 has a ring structure. The inner surface of the third structural member 4633 is provided with a limiting protrusion 4633a. The number of the limiting protrusions 4633a can be one or multiple. When the number of the limiting protrusions 4633a is multiple, the multiple limiting protrusions 4633a are arranged at intervals. In the embodiment, the number of the limiting protrusions 4633a is two.

[0119] Please refer to Figure 17 , Figure 17 is Figure 10 the structural schematic view of the second fitting member 463 at different angles. The third structural member 4633 is fixedly connected to the top of the first structural member 4631. In addition, the limiting protrusion 4633a of the third structural member 4633 is arranged in the limiting side hole 4632b of the second structural member 4632. The limiting protrusion 4633a of the third structural member 4633 can slide in the Z-axis direction in the limiting side hole 4632b of the second structural member 4632. At this time, the second structural member 4632 is slidingly connected to the third structural member 4633. In addition, through the cooperation of the limiting protrusion 4633a of the third structural member 4633 and the limiting side hole 4632b of the second structural member 4632, the second structural member 4632 is prevented from rotating relative to the first structural member 4631 in the X-Y plane, thereby ensuring that the second structural member 4632 has better stability in the X-Y plane.

[0120] Please refer to Figure 18 and Figure 19 , Figure 18 is Figure 9 the structural schematic view of the lifting mechanism 46b at another angle. Figure 19 is Figure 4The part cross-sectional view of the camera module body 40a is shown at the line C-C. The second fitting member 463 is arranged inside the first fitting member 462. The first structure member 4631 of the second fitting member 463 is threadedly connected to the first fitting member 462, i.e. the outer thread of the first structure member 4631 of the second fitting member 463 is threadedly connected to the inner thread of the first fitting member 462 to form a thread connection structure. In this way, when the first fitting member 462 rotates, the first structure member 4631 of the second fitting member 463 can move along the Z-axis direction (including the positive direction and the negative direction of the Z-axis) relative to the first fitting member 462. Since the second structure member 4632 is elastically connected to the first structure member 4631 through the buffer member 4634, and the third structure member 4633 is fixedly connected to the first structure member 4631, at this time, the second structure member 4632 and the third structure member 4633 can also move along the Z-axis direction with the first structure member 4631.

[0121] In addition, the first boss 4631a is located between the second boss 4632a and the module circuit board 44. The third structure member 4633 is located on the side of the first structure member 4631 away from the module circuit board 44.

[0122] In addition, the bottom wall 4614 of the limiting member 461 is fixedly connected to the module support 44. Illustratively, the bottom wall 4614 of the limiting member 461 can be fixedly connected to the module support 44 by means of adhesive, screw locking, etc. The first fitting member 462 is arranged inside the limiting member 461. The gear portion 4621 of the first fitting member 462 is clamped between the module support 44 and the limiting surface 4615 of the limiting member 461. In this way, the mutual cooperation of the module support 44 and the limiting surface 4615 of the limiting member 461 can limit the movement of the first fitting member 462 along the Z-axis direction. In addition, the first fitting member 462 is also rotationally connected to the limiting member 461 and the module support 44.

[0123] Illustratively, the gear portion 4621 of the first fitting member 462 can be in contact with the limiting surface 4615 of the limiting member 461. The bottom surface of the gear portion 4621 of the first fitting member 462 can be in contact with the module support 44. At this time, the connection of the first fitting member 462, the module support 44 and the limiting member 461 is more stable.

[0124] Illustratively, the inner wall 4611 (see Figure 11 ) of the limiting member 461 can cooperate with the outer side surface of the gear portion 4621 of the first fitting member 462 to prevent the first fitting member 462 from deviating in the X-Y plane. In addition, the cooperation length between the inner wall 4611 (see Figure 11 ) of the limiting member 461 and the outer side surface of the gear portion 4621 of the first fitting member 462 can be increased to prevent the first fitting member 462 from tilting.

[0125] Please refer again toFigure 18 and Figure 19 The driving mechanism 46a is fixedly connected to the module circuit board 41 and electrically connected to the module circuit board 41. In this way, the driving mechanism 46a can be powered by the module circuit board 41 to be in an active state.

[0126] In addition, the output end 460a (see Figure 9 ) of the driving mechanism 46a can pass through the gap 4615 of the limiting member 461 and engage with the gear part 4621 (see Figure 18 ) of the first engaging member 462. In this way, when the output end 460a (see Figure 9 ) of the driving mechanism 46a rotates, the first engaging member 462 rotates around the Z-axis direction. Since the first engaging member 462 is threadedly connected to the first structure part 4631 of the second engaging member 463, the first structure part 4631 of the second engaging member 463 can move along the Z-axis direction at this time. Since the second structure part 4632 is elastically connected to the first structure part 4631 of the second engaging member 463 by the buffer member 4634, and the third structure part 4633 is fixedly connected to the first structure part 4631, the second structure part 4632 and the third structure part 4633 can also move along the Z-axis direction with the first structure part 4631.

[0127] In an embodiment, the lifting mechanism 46b further comprises a Hall sensor and a mechanism magnet. The Hall sensor is fixedly connected to the module support 44. The mechanism magnet is fixedly connected to the first structure part 4631, the second structure part 4632 or the third structure part 4633 of the second engaging member 463. The Hall sensor is used to detect the magnetic field strength of the mechanism magnet at different positions. In this way, when the second engaging member 463 moves along the Z-axis direction relative to the first engaging member 462, the displacement amount of the second engaging member 463 moving along the Z-axis direction is accurately controlled through the cooperation of the Hall sensor and the mechanism magnet. Exemplarily, the Hall sensor can be electrically connected to the module circuit board 41 through the wiring on the module support 44 by arranging the wiring on the module support 44.

[0128] Please refer to Figure 20 , Figure 20 is Figure 5An exploded view of the lens assembly 47 is shown. The lens assembly 47 includes a lens motor 471, a first lens 472, a second lens 473, a connecting mechanism 474, a variable aperture 475, a cover plate fixing frame 476, a lens cover plate 477, and a lens housing 478. The first lens 472 is disposed in the lens motor 471. The lens motor 471 is configured to drive the first lens 472 to move along the optical axis direction (i.e., the Z-axis direction, which includes the positive direction of the Z-axis and the negative direction of the Z-axis) of the camera module 40 to achieve auto focus (AF) of the first lens 472. The lens motor 471 can be a voice coil motor, an SMA (shape memory alloys) motor, or other types of motors. It should be understood that the SMA motor can be a type of motor that uses the contraction of SMA wire to generate driving force. The SMA wire can be made of a nickel-titanium alloy material. In addition, SMA is a general term for a type of metal that has a shape memory effect. In this embodiment, the lens motor 471 is described by way of example using a voice coil motor.

[0129] Referring to Figure 21 , Figure 21 is Figure 20 a partially exploded view of the lens motor 471. The lens motor 471 includes a base 4711, a first sliding rod 4712a, a second sliding rod 4712b, a fixed bracket 4713, a moving bracket 4714, a first coil 4715a, a second coil 4715b, a first motor magnet 4716a, a second motor magnet 4716b, a motor circuit board 4717, and a plurality of conductive pieces 4718.

[0130] Referring to Figure 22 , Figure 22 is Figure 21 a structural view of the base 4711 from another angle. The base 4711 is annular. The base has a first side hole 4711b and a second side hole 4711c arranged at intervals. The first side hole 4711b and the second side hole 4711c are oppositely arranged. In addition, the base also has a first fixing hole 4711d and a second fixing hole 4711e arranged at intervals.

[0131] Referring to Figure 23 , Figure 23 is Figure 21 a structural view of the fixed bracket 4713 from another angle. The fixed bracket 4713 is annular. The fixed bracket 4713 has a third fixing hole 4713a and a fourth fixing hole 4713b arranged at intervals.

[0132] Referring to Figure 24 , Figure 24 is Figure 21The mobile support 4714 is ring-shaped. The mobile support 4714 is also provided with first guide holes 4714a and second guide holes 4714b arranged at intervals. The mobile support 4714 is provided with first sliding holes 4714c and second sliding holes 4714d arranged at intervals. The first guide holes 4714a and the second guide holes 4714b are also arranged at intervals with the first sliding holes 4714c and the second sliding holes 4714d. In addition, the mobile support 4714 is also provided with first mounting grooves 4714e and second mounting grooves 4714f arranged in opposite directions.

[0133] Exemplarily, the first sliding holes 4714c can be circular, track-shaped or U-shaped. The second sliding holes 4714d can be V-shaped holes.

[0134] Please refer to Figure 25 , Figure 25 is Figure 20 The first sliding rod 4712a is fixedly connected to the base 4711 at one end and to the fixed support 4713 at the other end. The present embodiment takes the length extension direction of the first sliding rod 4712a as the Z-axis direction for description. Exemplarily, one end of the first sliding rod 4712a is inserted into the first fixed hole 4711d of the base 4711, and the other end is inserted into the third fixed hole 4713a of the fixed support 4713. In one embodiment, one end of the first sliding rod 4712a can be interference-fitted with the first fixed hole 4711d of the base 4711. The other end of the first sliding rod 4712a can be interference-fitted with the third fixed hole 4713a of the fixed support 4713. In other embodiments, one end of the first sliding rod 4712a can also be fixedly connected to the first fixed hole 4711d of the base 4711 by welding or bonding. The other end of the first sliding rod 4712a can also be fixedly connected to the third fixed hole 4713a of the fixed support 4713 by welding or bonding.

[0135] In addition, one end of the second slide rod 4712b is fixedly connected to the base 4711, and the other end is fixedly connected to the fixed support 4713. The embodiment is described taking the length extension direction of the second slide rod 4712b as the Z-axis direction as an example. Exemplarily, one end of the first slide rod 4712a is inserted into the second fixed hole 4711e of the base 4711, and the other end is inserted into the fourth fixed hole 4713b of the fixed support 4713. In one embodiment, one end of the second slide rod 4712b can be interference-fitted with the second fixed hole 4711e of the base 4711. The other end of the second slide rod 4712b can be interference-fitted with the fourth fixed hole 4713b of the fixed support 4713. In other embodiments, one end of the second slide rod 4712b can also be fixedly connected to the second fixed hole 4711e of the base 4711 by welding or bonding and the like. The other end of the second slide rod 4712b can also be fixedly connected to the fourth fixed hole 4713b of the fixed support 4713 by welding or bonding and the like.

[0136] In addition, the moving support 4714 is arranged on the inner side of the base 4711. The first slide rod 4712a passes through the first slide hole 4714c of the moving support 4714. The second slide rod 4712b passes through the second slide hole 4714d of the moving support 4714. The moving support 4714 can slide relative to the first slide rod 4712a and the second slide rod 4712b.

[0137] Exemplarily, the base 4711 can be fixedly connected with a magnetic guide sheet. The moving support 4714 is provided with a magnet. The magnet and the magnetic guide sheet can generate a magnetic force. The direction of the magnetic force received by the magnetic guide sheet is the direction of the magnetic guide sheet towards the magnet. The moving support 4714 is also subjected to the extrusion force of the magnet. In addition, since the second slide hole 4714d is a V-shaped hole, the second slide rod 4712b can be tightly fitted with the second slide hole 4714d under the extrusion of the moving support 4714.

[0138] In other embodiments, a buffer pad (not shown in the figure) can be arranged between the fixed support 4713 and the moving support 4714. The buffer pad is fixedly connected to the fixed support 4713 or the moving support 4714. The buffer pad can buffer the collision between the moving support 4714 and the fixed support 4713 during sliding.

[0139] Please refer to Figure 26 , Figure 26 is Figure 5 the partial cross-sectional schematic view of the lens assembly 47 shown in FIG. 47. The first motor magnet 4716a and the second motor magnet 4716b are fixedly connected to the moving support 4714. The first motor magnet 4716a and the second motor magnet 4716b are arranged opposite to each other. Exemplarily, the first motor magnet 4716a is fixedly connected in the first mounting groove 4714e of the moving support 4714 Figure 24The first mounting slot 4714e is shown from different angles. The second motor magnet 4716b is fixedly connected in the second mounting slot 4714f of the moving bracket 4714 Figure 24 The first mounting slot 4714e is shown from different angles.

[0140] Please refer to Figure 26 , and in combination with Figure 25 , it is shown that the first coil 4715a and the second coil 4715b are fixedly connected to the base 4711. The first coil 4715a is oppositely arranged with the first motor magnet 4716a. The second coil 4715b is oppositely arranged with the second motor magnet 4716b. It can be understood that when the first coil 4715a and the second coil 4715b are applied with signals, the first motor magnet 4716a can cooperate with the first coil 4715a, and the second motor magnet 4716b can cooperate with the second coil 4715b, so as to push the moving bracket 4714 to slide relative to the first slide rod 4712a and the second slide rod 4712b.

[0141] In other embodiments, the positions of the first motor magnet 4716a and the first coil 4715a can be reversed. The positions of the second motor magnet 4716b and the second coil 4715b can be reversed.

[0142] In addition, the motor circuit board 4717 is fixedly connected to the base 4711. The first coil 4715a and the second coil 4715b are electrically connected to the motor circuit board 4717. Exemplarily, by arranging wires on the base 4711, the wires can electrically connect the first coil 4715a to the motor circuit board 4717, or electrically connect the second coil 4715b to the motor circuit board 4717. In addition, the motor circuit board 4717 can be electrically connected to the module circuit board 41 through the module bracket 44 (please refer to Figure 19 ). Exemplarily, the module bracket 44 is provided with wires or a flexible circuit board. The motor circuit board 4717 is electrically connected to the module circuit board 41 through the module bracket 44 provided with wires or a flexible circuit board.

[0143] Please refer to Figure 26The lens motor 471 can further include a Hall sensor 4719. The Hall sensor 4719 is fixedly connected to the motor circuit board 4717 and electrically connected to the motor circuit board 4717. The Hall sensor 4719 is used to detect the magnetic field strength of the first motor magnet 4716a or the second motor magnet 4716b at different positions. In the embodiment, the Hall sensor 4719 is located in the area surrounded by the first coil 4715a. The Hall sensor 4719 is used to detect the magnetic field strength of the first motor magnet 4716a at different positions. In other embodiments, the number of Hall sensors 4719 can also be two. One is used to detect the magnetic field strength of the first motor magnet 4716a at different positions, and the other is used to detect the magnetic field strength of the second motor magnet 4716b at different positions. It can be understood that through the cooperation of the Hall sensor 4719 and the first motor magnet 4716a or the second motor magnet 4716b, the displacement of the moving bracket 4714 sliding along the Z-axis direction can be accurately controlled.

[0144] In other embodiments, the lens motor 471 can further include an IC chip. The IC chip can be electrically connected to the first coil 4715a and the second coil 4715b for controlling the operation of the first coil 4715a and the second coil 4715b. In addition, the IC chip also has the function of a Hall sensor, that is, the IC chip can be used to detect the magnetic field strength of the first motor magnet 4716a or the second motor magnet 4716b at different positions. Thus, through the cooperation of the IC chip and the first motor magnet 4716a or the second motor magnet 4716b, the displacement of the moving bracket 4714 sliding along the Z-axis direction can be accurately controlled.

[0145] Please refer again to Figure 26 , and in combination with Figure 25 , it is shown that the first lens 472 includes a first lens barrel 4721 and a first lens 4722. The number of first lenses 4722 can be one or more. When the number of first lenses 4722 is more, the first lenses 4722 are arranged in sequence along the Z-axis direction. The number of first lenses 4722 in the embodiment is six. The first lenses 4722 are fixedly connected in the first lens barrel 4721.

[0146] In addition, the first lens 472 is located inside the moving bracket 4714. The first lens barrel 4721 of the first lens 472 is fixedly connected to the moving bracket 4714. When the moving bracket 4714 slides relative to the first slide rod 4712a and the second slide rod 4712b, the first lens 472 can slide relative to the first slide rod 4712a and the second slide rod 4712b along with the moving bracket 4714, that is, the first lens 472 can move along the Z-axis direction along with the moving bracket 4714. In this way, the first lens 472 can realize the focusing function under the drive of the lens motor 471.

[0147] Please refer back to Figure 26 The variable aperture 475 is located on the light-in side of the first lens 472, and the variable aperture 475 can be fixedly connected to the first lens 472. The variable aperture 475 can be used to increase or decrease the light flux entering the first lens 472. For example, when the electronic device 100 is used to take a photo in a dark light condition, the aperture hole of the variable aperture 475 can be adjusted to be large, at this time, the light flux entering the first lens 472 is increased. When the electronic device 100 is used to take a photo in a light sufficient condition, the aperture hole of the variable aperture 475 can be adjusted to be small, at this time, the light flux entering the first lens 472 is reduced.

[0148] In this embodiment, by fixing the variable aperture 475 on the first lens 472, when the lens motor 471 drives the first lens 472 to move along the Z-axis direction, the variable aperture 475 can also move along the Z-axis direction with the first lens 472. At this time, the position of the variable aperture 475 relative to the lens does not change in the process of the first lens 472 moving along the Z-axis direction. In this way, without considering other factors affecting the field angle of the first lens 472, when the position of the aperture hole of the variable aperture 475 relative to the first lens 472 does not change, the field angle of the first lens 472 also does not change.

[0149] Please refer back to Figure 26 , and in combination with Figure 20 It is shown that the lens shell 478 is annular. The lens shell 478 is fixedly connected to the base 4711. The lens shell 478 can be arranged around part of the lens motor 471, the first lens 472 and the variable aperture 475. The lens shell 478 can be used to protect the lens motor 471, the first lens 472 and the variable aperture 475. Among them, the lens motor 471 can be fixedly connected to the outside of the lens shell 478.

[0150] For example, the lens shell 478 can also be provided with a buffer pad. The buffer pad can buffer the collision of the moving support 4714 with the lens shell 478 in the sliding process.

Illustratively, a first trace is provided on the moving bracket 4714, and the first trace is electrically connected to the conductive sheet 4718 and the variable aperture 475. In addition, a second trace is provided on the base 4711, and the second trace can electrically connect the conductive sheet 4718 to the motor circuit board 4717. In this way, the variable aperture 475 can be electrically connected to the motor circuit board 4717 through the first trace, the conductive sheet 4718, and the second trace.

At this time, the first magnet 4747 is oppositely arranged with the first portion 4745a of the first limiting support 4745. It can be understood that, since the first limiting support 4745 is a magnetically conductive material, the first portion 4745a of the first limiting support 4745 can generate a magnetic force with the first magnet 4747.

The first guide rod 4741 and the first limiting portion 4732 have better stability.

[0169] Please refer to Figure 32 , and in combination with Figure 30 , it is shown that Figure 32 is Figure 5 partially cross-sectional schematic view of the lens assembly 47 shown.

The second portion 4746b of the second limiting support 4746 is fixedly connected to the second end of the second guide portion 4742b of the second guide rod 4742.

[0170] In addition, the first portion 4746a and the third portion 4746c of the second limiting support 4746 are fixedly connected to the moving support 4714. Exemplarily, the moving support 4714 can be provided with a recess. The first portion 4746a and the third portion 4746c of the second limiting support 4746 can be interference-fitted with the recess of the moving support 4714.

[0171] In addition, the second magnet 4748 is fixedly connected to the second limiting portion 4733 and is arranged opposite to the first portion 4746a of the second limiting support 4746. It can be understood that, since the second limiting support 4746 is a magnetically conductive material, the first portion 4746a of the second limiting support 4746 can generate a magnetic force with the second magnet 4748. The direction of the magnetic force acting on the second magnet 4748 is the direction in which the first portion 4746a of the second limiting support 4746 is directed towards the second magnet 4748. The second limiting portion 4733 is also subjected to the extrusion force of the second magnet 4748. The second guide rod 4742 can be tightly fitted with the fourth guide hole 4735 of the second limiting portion 4733 under the extrusion of the second limiting portion 4733.

The first annular wall 4761 is fixedly connected to the inner periphery of the bottom wall 4763. The second annular wall 4762 is fixedly connected to the outer periphery of the bottom wall 4763. The space is enclosed between the first annular wall 4761 and the second annular wall 4762. The inner side of the first annular wall 4761 encloses the inner side space of the cover plate fixing frame 476.

[0173] Please refer to Figure 34 , Figure 34 is Figure 3 The partial cross-sectional view of the camera module 40 at the D-D line is shown. The first annular wall 4761 of the cover plate fixing frame 476 is fixedly connected to the second structure 4632 of the second fitting piece 463. The second annular wall 4762 of the cover plate fixing frame 476 is fixedly connected to the first sealing ring 48a (shown in combination with Figure 5 ).

[0177] The lens cover 477 is fixedly connected to the bottom wall 4763 of the cover mounting bracket 476. The lens cover 477 is located on the side of the first lens 472 away from the photosensitive chip 42 and is arranged opposite the first lens 472. The lens cover 477 allows light from outside the camera module 40 to pass through. Ambient light passing through the lens cover 477 is transmitted through the variable aperture 475, the first lens 472, the second lens 473, the filter 45, and finally to the photosensitive chip 43.

[0178] The above describes in detail the specific structure of each part of the camera module 40 through the relevant drawings. The following describes in detail an embodiment of the positional relationship between the various components when the camera module 40 is in the start position, the intermediate position and the stop position through the relevant drawings.

[0179] Please refer again Figure 34 When the camera module 40 is in the stopped position, the second lens 473 is located between the first lens 472 and the photosensitive chip 43. The second lens barrel 473a of the second lens 473 contacts the module bracket 44. At this time, the distance between the second lens 473 and the photosensitive chip 43 is a first distance. The first distance can be the minimum distance between the second lens 473 and the photosensitive chip 43 when the camera module 40 is in the stopped position.

[0180] In addition, the first structural member 4631 of the second matching member 463 contacts the module bracket 44. The first limiting bracket 4745 (combined with Figure 31 The second portion 4745b shown) and the second limiting bracket 4746 (combined with Figure 32 The second portion 4745b of the camera module 40 (shown in FIG. 4A ) is in contact with the module bracket 44. At this time, the distance between the first lens 472 and the second lens 473 is the third distance. The third distance can be the minimum distance between the first lens 472 and the second lens 473 when the camera module 40 is in the stopped position.

[0181] In addition, the first sealing ring 48a is arranged in contact with the limiter 461 of the lifting mechanism 46b.

[0182] See also Figure 35 ,Figure 35 is Figure 34 is a partial cross-sectional view of the camera module 40 in the middle position. When the camera module 40 is in the middle position, the second lens 473 is located between the first lens 472 and the photosensitive chip 43. The second lens 473 is located opposite the first lens 472 and the photosensitive chip 43. The second lens barrel 473a of the second lens 473 is in contact with the module support 44. At this time, the relative position between the second lens 473 and the photosensitive chip 43 does not change.

[0183] In addition, the first structure 4631 of the second fitting member 463 is spaced apart from the module support 44. The distance between the first structure 4631 of the second fitting member 463 and the module support 44 is a fifth distance. Figure 31 The second part 4745b of the first limiting support 4745 (in combination with Figure 32 The second part 4745b of the second limiting support 4746 (in combination with At this time, the distance between the first lens 472 and the second lens 473 is a fourth distance. The fourth distance can be the minimum distance between the first lens 472 and the second lens 473 when the camera module 40 is in the middle position. The fourth distance is greater than the third distance.

[0184] In addition, the waterproof silica gel sleeve 49 deforms. The deformation amount of the waterproof silica gel sleeve 49 is a first deformation amount. The first sealing ring 48a is spaced apart from the limiting member 461 of the lifting mechanism 46b.

[0185] Please refer to Figure 36 , Figure 36 is Figure 34 is a partial cross-sectional view of the camera module 40 in the starting position. When the camera module 40 is in the starting position, the second lens 473 is located between the first lens 472 and the photosensitive chip 43. The second lens barrel 473a of the second lens 473 is spaced apart from the module support 44. At this time, the distance between the second lens 473 and the photosensitive chip 43 is a second distance. The second distance is greater than the first distance. The distance between the second lens 473 and the photosensitive chip 43 increases.

[0186] In addition, the first structure 4631 of the second fitting member 463 is spaced apart from the module support 44. The distance between the first structure 4631 of the second fitting member 463 and the module support 44 is a sixth distance. The sixth distance is greater than the fifth distance.

[0187] The second part 4745b of the first limiting support 4745 (in combination with Figure 31The second portion 4745b of the second lens barrel 473a of the second lens 473 contacts the first limiting portion 4732. The second limiting bracket 4746 (combined with Figure 32 The second portion 4746b of the second lens 473 (shown in FIG. 47) contacts the second stopper 4733 of the second lens barrel 473a of the second lens 473. At this time, the relative position between the second lens 473 and the first lens 472 does not change.

[0188] In addition, the waterproof silicone sleeve 49 is deformed. The deformation of the waterproof silicone sleeve 49 is a second deformation. The second deformation is greater than the first deformation. The first sealing ring 48a is spaced apart from the limiting member 461 of the lifting mechanism 46b.

[0189] Please refer again Figure 34 and Figure 35 , and combined with Figure 30 As shown, when the camera module 40 is converted from the stop position to the middle position, the driving mechanism 46a drives the first fitting part 462 to rotate. Since the first structural part 4631 of the second fitting part 463 is threadedly connected to the first fitting part 462, and the first fitting part 462 is fixedly connected to the module bracket 44, the first structural part 4631 of the second fitting part 463 can move relative to the first fitting part 462 along the positive direction of the Z axis. Since the second structural part 4632 of the second fitting part 463 is elastically connected to the first structural part 4631 of the second fitting part 463, the second structural part 4632 can move along the positive direction of the Z axis with the first structural part 4631. Since the lens motor 471 (combined with Figure 26 The base 4711 is fixedly connected to the second structural member 4632 of the second matching member 463, and the first lens 472 is fixedly connected to the mobile bracket 4714 (combined with Figure 26As shown in FIG. 17, when the camera module 40 is in the starting position, the first structure 4631 of the second cooperating member 463 can move along the positive direction of the Z axis, and the second structure 4632 of the second cooperating member 463 can move along the positive direction of the Z axis. The lens motor 471 and the first lens 472 can move along the positive direction of the Z axis as the second structure 4632 of the second cooperating member 463 moves along the positive direction of the Z axis. Since the first fixed part 4741a of the first guide rod 4741 is fixedly connected to the moving bracket 4714 of the first lens 472, the second fixed part 4742a of the second guide rod 4742 is fixedly connected to the moving bracket 4714, the second part 4745b of the first limiting bracket 4745 is fixedly connected to the second end of the first guide part 4741b of the first guide rod 4741, the second part 4745b of the second limiting bracket 4746 is fixedly connected to the second end of the second guide part 4742b of the second guide rod 4742, and the first guide rod 4741, the second guide rod 4742, the first limiting bracket 4745 and the second limiting bracket 4746 move along the moving bracket 4714 along the direction of the Z axis. When the camera module 40 is in the intermediate position, the second part 4745b of the first limiting bracket 4745 moves to contact the first limiting part 4732 of the second lens barrel 473a of the second lens 473, and the second part 4745b of the second limiting bracket 4746 moves to contact the second limiting part 4733 of the second lens barrel 473a of the second lens 473.

[0190] In addition, since the first annular wall 4761 of the cover plate fixing bracket 476 is fixedly connected to the second structure 4632 of the second cooperating member 463, the second annular wall 4762 of the cover plate fixing bracket 476 is fixedly connected to the first sealing ring 48a, and the lens cover plate 477 is fixedly connected to the bottom wall 4763 of the cover plate fixing bracket 476, at this time, the cover plate fixing bracket 476, the first sealing ring 48a and the lens cover plate 477 all move along the positive direction of the Z axis.

[0191] It can be understood that when the camera module 40 is converted from the stopping position to the intermediate 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 stationary state, and the first lens 472 moves along the positive direction of the Z axis relative to the photosensitive chip 43, 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 stopping position, the relative position between the second lens 473 and the photosensitive chip 43 does not move, and the first lens 472 moves along the negative direction of the Z axis relative to the photosensitive chip 43, at this time, the distance between the second lens 473 and the first lens 472 decreases.

[0192] Please refer to Figure 35 and Figure 36 , and in combination with Figure 30 As shown in FIG. 17, when the camera module 40 is in the starting position, the first structure 4631 of the second cooperating member 463 can move along the positive direction of the Z axis, and the second structure 4632 of the second cooperating member 463 can move along the positive direction of the Z axis. The lens motor 471 and the first lens 472 can move along the positive direction of the Z axis as the second structure 4632 of the second cooperating member 463 moves along the positive direction of the Z axis. Since the first fixed part 4741a of the first guide rod 4741 is fixedly connected to the moving bracket 4714 of the first lens 472, the second fixed part 4742a of the second guide rod 4742 is fixedly connected to the moving bracket 4714, the second part 4745b of the first limiting bracket 4745 is fixedly connected to the second end of the first guide part 4741b of the first guide rod 4741, the second part 4745b of the second limiting bracket 4746 is fixedly connected to the second end of the second guide part 4742b of the second guide rod 4742, and the first guide rod 4741, the second guide rod 4742, the first limiting bracket 4745 and the second limiting bracket 4746 move along the moving bracket 4714 along the direction of the Z axis. When the camera module 40 is in the intermediate position, the second part 4745b of the first limiting bracket 4745 moves to contact the first limiting part 4732 of the second lens barrel 473a of the second lens 473, and the second part 4745b of the second limiting bracket 4746 moves to contact the second limiting part 4733 of the second lens barrel 473a of the second lens 473.Figure 26 The first lens 472 can also continue to move along the positive direction of the Z axis with the second structure 4632. The first guide rod 4741, the second guide rod 4742, the first limiting support 4745, and the second limiting support 4746 continue to move along the positive direction of the Z axis with the moving support 4714. Since the second part 4745b of the first limiting support 4745 is in contact with the first limiting part 4732 of the second lens barrel 473a of the second lens 473, and the second part 4745b of the second limiting support 4746 is in contact with the second limiting part 4733 of the second lens barrel 473a of the second lens 473, the first limiting support 4745 and the second limiting support 4746 can pull the second lens 473 to move along the positive direction of the Z axis.

[0193] It can be understood that when the camera module 40 is converted from the intermediate position to the starting position, the second lens 473 moves along the positive direction of the Z axis relative to the photosensitive chip 43, and the distance between the second lens 473 and the photosensitive chip 43 increases. In addition, since the first lens 472 and the second lens 473 both 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 intermediate position, the second lens 473 moves along the negative direction of the Z axis relative to the photosensitive chip 43, and the distance between the second lens 473 and the photosensitive chip 43 decreases. In addition, since the first lens 472 and the second lens 473 both 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.

[0194] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
