Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without undue burden, are within the scope of the present application.

Reference herein to "an embodiment" or "an implementation" means that a particular feature, structure, or characteristic described in connection with the embodiment or implementation may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Periscope type cameras are necessary modules for enhancing the image experience of users, and most electronic devices (such as mobile phones) are mounted on the periscope type cameras. To meet a better imaging experience, the photosensitive element 122 of the periscope camera needs to meet the corresponding requirements. Taking a folding screen phone as an example, the size of the photosensitive element 122 needs to be 1/2.0", and the height requirement of the thickness of the folding screen phone for the periscope is 6.0mm (inclusive) or less. The normal upright (upright means that the height of the photosensitive element 122 is consistent with the height of the periscope camera) is that the 1/2.0 "photosensitive element 122 is stacked to be greater than 6.0mm, and typically 6.7-6.95mm, which is not competitive for folding screen phones.

Based on this, the present application intends to provide a solution to the above technical problems, but not limited to, the details of which will be described in the following examples.

Referring to fig. 1 to 7, the present application provides a camera module 10, where the camera module 10 is a periscope type camera. The camera module 10 has a first state (as shown in fig. 4 or fig. 6) and a second state (as shown in fig. 5 or fig. 7). The camera module 10 includes a carrier 11 and a photosensitive assembly 12. The photosensitive assembly 12 is a device for processing light in the camera module 10, and the bearing seat 11 is an outer shell for bearing and protecting the photosensitive assembly 12 and other devices in the camera module 10. The bearing seat 11 can be, but is not limited to, a cuboid structure, a cube structure, or the like.

The carrying seat 11 includes a movable cover 111 and a carrying body 112. Wherein the carrying body 112 includes a first carrying portion 1121, and the movable cover 111 includes a first movable portion 1111. The first carrying portion 1121 is opposite to the first movable portion 1111 and spaced apart from the first movable portion 1111. The opposite direction of the first carrying portion 1121 and the first moving portion 1111 is a preset direction, and the first moving portion 1111 may be far away from or near to the first carrying portion 1121 along the preset direction.

The photosensitive assembly 12 is disposed between the first movable portion 1111 and the first carrying portion 1121, and can receive light and convert an optical signal into an electrical signal. When the camera module 10 is in the first state, the height of the photosensitive assembly 12 in the preset direction is a first height, and the distance from the first movable portion 1111 to the first carrying portion 1121 is a first distance. When the camera module 10 is in the second state, the height of the photosensitive assembly 12 in the preset direction is a second height, and the distance from the first movable portion 1111 to the first carrying portion 1121 is a second distance. Wherein the first height is less than the second height and the first distance is less than the second distance.

It should be noted that, in the embodiments of the present application, the height of the photosensitive assembly 12 in the preset direction refers to the projection height of the photosensitive assembly 12 in the preset direction. The height direction of the camera module 10 is parallel to the preset direction.

From a dynamic process point of view: in the process of the camera module 10 changing from the first state to the second state, the height of the photosensitive assembly 12 in the preset direction gradually increases from the first height to the second height, and the first movable portion 1111 gradually moves away from the first bearing portion 1121 along the preset direction and the distance between the first movable portion and the second movable portion gradually increases from the first distance to the second distance. In contrast, in the process of the camera module 10 being changed from the second state to the first state, the height of the photosensitive assembly 12 in the preset direction is gradually reduced from the second height to the first height, and the first movable portion 1111 is gradually close to the first bearing portion 1121 along the preset direction, and the distance between the first movable portion and the first movable portion is gradually reduced from the second distance to the first distance.

It can be appreciated that when the distance between the first movable portion 1111 and the first carrier portion 1121 increases, this means that the height of the camera module 10 increases. Also, when the distance between the first movable portion 1111 and the first carrier portion 1121 is reduced, it means that the height of the camera module 10 is reduced. The height of the camera module 10 refers to the distance between the outer surfaces of the camera module 10 in the preset direction. Specifically, the first movable portion 1111 has a first outer surface M1 facing away from the first carrying portion 1121, the first carrying portion 1121 has a second outer surface M2 facing away from the first movable portion 1111, and a distance between the first outer surface M1 and the second outer surface M2 is a height of the camera module 10. When the distance between the first movable portion 1111 and the first carrier portion 1121 increases, the distance between the first outer surface M1 and the second outer surface M2 increases, so that the height of the camera module 10 increases. When the distance between the first movable portion 1111 and the first carrier portion 1121 is reduced, the distance between the first outer surface M1 and the second outer surface M2 is reduced, so that the height of the camera module 10 is reduced.

Alternatively, when the camera module 10 is in the first state, the photosensitive assembly 12 assumes a curved state or an inclined state.

Alternatively, when the camera module 10 is in the second state, the photosensitive assembly 12 is in an upright state, and at this time, the height of the photosensitive assembly 12 in the preset direction reaches a maximum value.

In summary, in the camera module 10 provided in the present application, the photosensitive component 12 may change the height in a preset direction, and the first movable portion 1111 may move along the preset direction, so that the camera module 10 has a first state and a second state. When the camera module 10 is in the second state, since the height of the photosensitive assembly 12 is the second height, the distance between the first movable portion 1111 and the first carrying portion 1121 needs to be kept at the second distance, and the height of the camera module 10 is larger. When the camera module 10 is in the second state, since the height of the photosensitive assembly 12 is the first height, the distance between the first movable portion 1111 and the first carrying portion 1121 may be reduced from the second distance to the first distance, and the height of the camera module 10 at this time is smaller. That is, the height of the camera module 10 provided in the present application may be changed, and the thickness of the camera module 10 is reduced after the camera module is switched from the second state to the first state. Therefore, the thickness of the camera module 10 provided by the present application can be smaller than that of the related art under the condition that the photosensitive elements 12 are the same size. When the camera module 10 provided by the application is applied to the electronic device 100, the thickness of the electronic device 100 can be designed according to the height corresponding to the camera module 10 in the first state, so that the thickness of the electronic device 100 can be made thinner.

Referring to fig. 2, the movable cover 111 and the carrying body 112 together form a housing space S. The first movable portion 1111 has a light-transmitting portion T, and the light-transmitting portion T can transmit light, so that the light can enter the accommodating space S. The light transmitting portion T may be a through hole in the first movable portion 1111 or a transparent solid portion in the first movable portion 1111. The camera module 10 further includes a reflector 14 and a lens group 15 disposed in the accommodating space S. The reflecting mirror 14 faces the light transmitting portion T, and the reflecting mirror 14 is configured to reflect light from the light transmitting portion T to the lens group 15. The type of mirror 14 may be, but is not limited to, a flat mirror, a triangular prism, etc. A lens group 15 is disposed between the reflecting mirror 14 and the photosensitive member 12, and the lens group 15 is used for focusing the light from the reflecting mirror 14 to the photosensitive member 12. The lens group 15 includes a plurality of lenses, and the material of the lenses may be glass, plastic, or the like.

Referring to fig. 3, the photosensitive assembly 12 includes a circuit board 121 and a photosensitive element 122, the photosensitive element 122 is disposed on the circuit board 121, the circuit board 121 is electrically connected to the photosensitive element 122, and the circuit board 121 is disposed on a side of the photosensitive element 122 away from the lens group 15. By this arrangement, the circuit board 121 can be prevented from blocking the light emitted from the lens assembly 15 to the photosensitive assembly 12, thereby ensuring good imaging effect of the camera module 10. The photosensitive element 122 is also called a photosensitive chip or an image Sensor or a Sensor, and the photosensitive element 122 is configured to receive the light from the lens group 15 and convert the light signal into an electrical signal. The photosensitive element 122 may be a charge coupled device (Charge Coupled Device, CCD) or a complementary metal oxide conductor device (Complementary Metal Oxide Semiconductor, CMOS).

Further, possible embodiments (including the following one and two embodiments) of the photosensitive member 12 for generating a height change in a predetermined direction are described below.

Referring to fig. 4 and 5, in an embodiment, the photosensitive assembly 12 is bendable, the camera module 10 further includes a driving member 13, and the driving member 13 is connected to the photosensitive assembly 12 and the first carrying portion 1121 or the first movable portion 1111. The driving member 13 is configured to deform when the temperature changes, so as to drive the photosensitive assembly 12 to change shape, so that the height of the photosensitive assembly 12 in the preset direction changes. That is, in the present embodiment, the driving member 13 will change shape due to temperature change, and since the photosensitive member 12 is bendable, when the driving member 13 is deformed, the photosensitive member 12 will change shape the same as the driving member 13, thereby realizing the height change of the photosensitive member 12 in the predetermined direction. It can be understood that the form of driving the photosensitive assembly 12 to deform by the deformation generated by the temperature change of the driving member 13 does not need to provide an additional complicated mechanical driving structure, which is beneficial to the miniaturization design requirement of the camera module 10. It should be noted that, in the present embodiment, the driving member 13 is connected to a side of the photosensitive assembly 12 facing away from the lens group 15.

Wherein photosensitive assembly 12 comprises at least a portion of a flexible material such that photosensitive assembly 12 can flex flexibly. The flexible material refers to a material which has good flexibility, ductility and even can be freely bent or folded relative to a rigid material, and can be, but not limited to, polyvinyl alcohol, polyester, polyimide, polyethylene naphthalate and the like. When the driving member 13 is bent, the driving member 13 drives the photosensitive assembly 12 to bend, and the bending directions of the photosensitive assembly 12 and the driving member 13 are the same; when the driving member 13 straightens in the predetermined direction, the driving member 13 drives the photosensitive assembly 12 to straighten in the predetermined direction.

Wherein the driving member 13 may be, but is not limited to, a memory alloy. The memory alloy has the characteristic of eliminating deformation of the memory alloy at low temperature after heating. In the present embodiment, when the memory alloy is in the first temperature range (low temperature range), the driving member 13 is in a curved state, so as to drive the photosensitive assembly 12 to be in a curved state (as shown in fig. 4). When the memory alloy is in the second temperature range (high temperature range), the driving member 13 is in an upright state, so as to drive the photosensitive assembly 12 to be in an upright state (as shown in fig. 5). Wherein the first temperature interval is smaller than the second temperature interval. Therefore, when the camera module 10 is switched between the first state (as shown in fig. 4) and the second state (as shown in fig. 5), the temperature of the memory alloy can be controlled to be switched between the first temperature interval and the second temperature interval.

The circuit board 121 and the photosensitive element 122 each contain at least part of a flexible material so that the circuit board 121 and the photosensitive element 122 can be flexibly bent. The photosensitive element 122 is disposed on the circuit board 121, and the driving member 13 is connected to a side of the circuit board 121 facing away from the photosensitive element 122. When the driving member 13 deforms, the circuit board 121 and the photosensitive element 122 are driven by the driving member 13 to deform the same. When the driving member 13 is bent, the driving member 13 drives the circuit board 121 and the photosensitive element 122 to bend, and the bending directions of the circuit board 121 and the photosensitive element 122 are the same as the bending direction of the driving member 13; when the driving member 13 straightens in the predetermined direction, the driving member 13 drives the circuit board 121 and the photosensitive element 122 to straighten in the predetermined direction.

Alternatively, the driving member 13 is connected to the photosensitive assembly 12 and the first carrier 1121 (as shown in fig. 4 and 5). Specifically, the carrying body 112 may further include a heat conducting portion 1123 connected to the side of the first carrying portion 1121 facing the first movable portion 1111, and one end of the driving member 13 away from the first movable portion 1111 is connected to the heat conducting portion 1123, that is, the driving member 13 is indirectly connected to the first carrying portion 1121 through the heat conducting portion 1123. The heat conduction portion 1123 is for supplying heat to the driving piece 13 to heat the driving piece 13, and for absorbing heat of the driving piece 13 to cool the driving piece 13. The heat conductive portion 1123 may be made of a material having a relatively high heat conductivity so as to rapidly transfer heat to the driving member 13 and rapidly absorb heat of the driving member 13.

Alternatively, the driving member 13 is connected to the photosensitive member 12 and the first movable portion 1111 (not shown). The carrying body 112 may further include a heat conducting portion 1123 connected to the first movable portion 1111 facing the first carrying portion 1121, and an end of the driving member 13 remote from the first carrying portion 1121 is connected to the heat conducting portion 1123, that is, the driving member 13 is indirectly connected to the first movable portion 1111 through the heat conducting portion 1123. The heat conduction portion 1123 is for supplying heat to the driving piece 13 to heat the driving piece 13, and for absorbing heat of the driving piece 13 to cool the driving piece 13. The heat conductive portion 1123 may be made of a material having a relatively high heat conductivity so as to rapidly transfer heat to the driving member 13 and rapidly absorb heat of the driving member 13. It will be appreciated that when the first movable portion 1111 moves in the preset direction, the photosensitive member 12 will also move in the preset direction.

Referring to fig. 6 and 7, in two embodiments, the camera module 10 further includes a driving member 13 carried by the carrying body 112. The driving member 13 is connected to the photosensitive assembly 12 and is used for driving the photosensitive assembly 12 to rotate, so that the height of the photosensitive assembly 12 in a preset direction is changed. That is, in the present embodiment, the driving member 13 drives the photosensitive assembly 12 to rotate, so as to change the inclination angle of the photosensitive assembly 12, and it is understood that the inclination angle is different, and the height of the photosensitive assembly 12 in the preset direction is different.

Specifically, when the camera module 10 is switched from the first state to the second state (i.e., the photosensitive assembly 12 is changed from the tilted state to the upright state), the tilt angle of the photosensitive assembly 12 gradually decreases. Conversely, when the camera module 10 is switched from the second state to the first state (i.e., the photosensitive assembly 12 is changed from the upright state to the inclined state), the inclination angle of the photosensitive assembly 12 gradually increases. It will be appreciated that the form of the photosensitive member 12 in the predetermined direction is changed by the rotation of the photosensitive member 12 by the driving member 13, and the shape of the photosensitive member 12 is not changed as compared with the previous embodiment, and the image forming effect can be ensured.

Referring to fig. 6 and 7, in the above two embodiments, optionally, an end of the photosensitive element 12 away from the first movable portion 1111 is rotatably connected to the carrying body 112. Opposite ends of the driving member 13 are respectively connected to the carrying body 112 and the photosensitive assembly 12. The driving member 13 may be extended or contracted and is used to drive the photosensitive member 12 to rotate during the extension or contraction. When the driving member 13 extends, the driving member 13 pushes the photosensitive assembly 12 to rotate clockwise, and the inclination angle of the photosensitive assembly 12 is reduced; when the driving member 13 is shortened, the photosensitive member 12 is rotated clockwise, and the inclination angle of the photosensitive member 12 is reduced.

The driving member 13 includes a first end D1 and a second end D2 (as shown in fig. 7) disposed opposite to each other, and in one embodiment, the first end D1 is fixedly connected to the carrying body 112, and the second end D2 is slidably connected to the photosensitive assembly 12. In another embodiment, the first end D1 is rotatably coupled to the carrier body 112, and the second end D2 is slidably coupled to the photosensitive assembly 12. In the two forms, the photosensitive assembly 12 is rotated, and the driving member 13 is moved in a linear manner, so that if the first end D1 and the second end D2 of the driving member 13 are respectively and fixedly connected to the supporting body 112 and the photosensitive assembly 12, the photosensitive assembly 12 is blocked and cannot move, and the driving member 13 cannot realize the telescopic function. The two embodiments can increase the freedom of movement of the driving member 13, so that the driving member 13 can be normally extended and contracted, and the photosensitive assembly 12 is driven to rotate.

The driving member 13 may be slidably telescopic. For example, the driver 13 includes a piston rod and a sleeve. Wherein, the sleeve is connected to the bearing body 112, and the piston rod is connected to the photosensitive assembly 12. The piston rod is arranged in the sleeve, namely the sleeve is sleeved on the periphery of the piston rod, the piston rod and the sleeve are in sliding fit, and the piston rod extends out of the sleeve and is retracted in the sleeve through sliding.

The driving member 13 may also be rotatably telescopic. For example, the driving member 13 includes a screw cylinder and a threaded rod. The screw cylinder is connected to the carrying body 112, and the threaded rod is connected to the photosensitive assembly 12. The threaded rod is provided with external threads, the threaded cylinder is provided with internal threads, and the threaded rod is screwed into the threaded cylinder through threads. When the threaded rod rotates, the threaded rod can extend out of the threaded cylinder or retract into the threaded cylinder.

Of course, the telescopic form of the driving member 13 may also take other possible forms, which are not described in detail here.

The bearing body 112 may further include a connection portion 1124, the connection portion 1124 is connected to the first bearing portion 1121, and the photosensitive assembly 12 is rotatably connected to the first bearing portion 1121 through the connection portion 1124. The engagement between the photosensitive member 12 and the connecting portion 1124 may be, but not limited to, a shaft/hole type engagement. The connecting portion 1124 may protrude from the surface of the first carrying portion 1121 facing the first movable portion 1111, so that an end of the photosensitive member 12 away from the first movable portion 1111 may be prevented from interfering with the first carrying portion 1121 during rotation.

Referring to fig. 8 and 9, in the above two embodiments, optionally, the driving member 13 is a motor, and the motor includes a motor body 131 and an output shaft 132 connected to each other. The motor body 131 is connected to the bearing body 112, and the motor body 131 can drive the output shaft 132 to rotate relative to the bearing body 112. The output shaft 132 of the motor is directly or indirectly connected to the photosensitive assembly 12 to drive the photosensitive assembly 12 to rotate.

Referring to fig. 8, in one embodiment, the rotation direction of the output shaft 132 of the motor is the same as the rotation direction of the photosensitive assembly 12. In this form, the output shaft 132 of the motor may be directly connected to the photosensitive assembly 12, but may be indirectly connected to the photosensitive assembly 12 through a coupling or the like.

Referring to fig. 9, in another embodiment, the rotation direction of the output shaft 132 of the motor is different from the rotation direction of the photosensitive assembly 12. In this form, the motor is indirectly coupled to the photosensitive assembly 12. For example, the rotation center line of the output shaft 132 of the motor is perpendicular to the rotation center line of the photosensitive assembly 12, in which form the motor and the photosensitive assembly 12 can be driven by a double bevel gear form, a worm wheel/worm form.

Further, in the above embodiments with respect to the driving member 13 and not in conflict, the driving member 13 is disposed at a side of the photosensitive assembly 12 facing away from the lens group 15. By this arrangement, the driving member 13 can be prevented from blocking the light emitted from the lens assembly 15 to the photosensitive assembly 12, so as to ensure that the camera module 10 has a good imaging effect.

Further, how to light seal the carrying seat 11 (including the following embodiment and two embodiments) will be described below with reference to the accompanying drawings.

Referring to fig. 10, in an embodiment, the bearing body 112 further includes a second bearing portion 1122, and the second bearing portion 1122 is bent and connected to the periphery of the first bearing portion 1121 and is disposed around the first bearing portion 1121. That is, the second bearing portion 1122 extends from the periphery of the first bearing portion 1121 toward the direction of the first movable portion 1111, and extends around the first bearing portion 1121 along the edge of the first bearing portion 1121.

The movable cover 111 further includes a second movable portion 1112 that is bent and connected to the first movable portion 1111, and the second movable portion 1112 is movably connected to the second bearing portion 1122. That is, the second movable portion 1112 extends from the periphery of the first movable portion 1111 toward the first carrying portion 1121, and is connected to the second carrying portion 1122. It should be noted that, the first movable portion 1111 and the second movable portion 1112 are fixedly connected, and move synchronously along a predetermined direction. The second movable portion 1112 and the second bearing portion 1122 may be slidably connected via a rail/groove, or may be rollably connected via rolling elements (e.g., balls, cylinders), etc. Wherein, the sliding connection through the guide rail/groove means that one of the second movable portion 1112 and the second bearing portion 1122 is provided with the guide rail, the other is provided with the groove, and the extending direction of the guide rail/groove is the same as the preset direction, and the sliding fit is performed through the form of the guide rail/groove. The rolling connection by the rolling element means that the rolling element is disposed between the second movable portion 1112 and the second bearing portion 1122 so that friction when the second movable portion 1112 moves relative to the second bearing portion 1122 is rolling friction.

Further, in the process of switching the first state and the second state of the camera module 10, at least a portion of the orthographic projection of the second movable portion 1112 on the second bearing portion 1122 always falls within the range of the second bearing portion 1122. Thus, external light can be prevented from entering the bearing seat 11.

Specifically, since the first movable portion 1111 is movable along the preset direction, when the first movable portion 1111 is far away from the first bearing portion 1121, the distance between the first movable portion 1111 and the second bearing portion 1122 increases, and if the second movable portion 1112 is not provided, a gap exists between the first movable portion 1111 and the second bearing portion 1122, and external light may enter the bearing seat 11 from the gap, so as to reach the photosensitive assembly 12. In this embodiment, at least a part of the orthographic projection of the second movable portion 1112 on the second bearing portion 1122 always falls within the range of the second bearing portion 1122, that is, the second movable portion 1112 always shields the gap between the first movable portion 1111 and the second bearing portion 1122, so that the external light is prevented from entering the bearing seat 11 through the gap. Therefore, the structural form provided by the embodiment can ensure that the camera module 10 has a better imaging effect.

Referring to fig. 11, in the two embodiments, the bearing body 112 further includes a second bearing portion 1122, and the second bearing portion 1122 is bent and connected to the periphery of the first bearing portion 1121 and is disposed around the first bearing portion 1121. The carrying seat 11 further includes a telescopic member 113 that is extendable or contractible in the predetermined direction, and the telescopic member 113 is connected between the second carrying portion 1122 and the first movable portion 1111. When the camera module 10 is changed from the first state to the second state, the expansion member 113 is elongated in the predetermined direction. When the camera module 10 is changed from the second state to the first state, the expansion member 113 is shortened in the predetermined direction. The expansion and contraction member 113 always seals the gap between the first movable portion 1111 and the second bearing portion 1122 during the process of being extended or contracted.

In the present embodiment, since the expansion member 113 is disposed between the first movable portion 1111 and the second bearing portion 1122, when the first movable portion 1111 is far from the first bearing portion 1121, the expansion member 113 can be correspondingly elongated, and when the first movable portion 1111 is close to the first bearing portion 1121, the expansion member 113 can be correspondingly shortened, thereby achieving the effect of always sealing the gap between the first movable portion 1111 and the second bearing portion 1122, so that external light cannot enter therethrough. Therefore, the structural form provided by the embodiment can ensure that the camera module 10 has a better imaging effect.

Referring to fig. 11, in the above two embodiments, optionally, the expansion member 113 is made of an elastic material, and the expansion member 113 is used for elastic expansion during the switching process of the first state and the second state of the camera module 10. Specifically, when the camera module 10 is switched from the first state to the second state, the first movable portion 1111 is far away from the first bearing portion 1121, and the telescopic member 113 is elastically elongated. When the camera module 10 is switched from the second state to the first state, the telescopic member 113 elastically contracts, so as to drive the first movable portion 1111 to approach the first bearing portion 1121. In this embodiment, the elastic material may be, but is not limited to, rubber.

Referring to fig. 11, in the above two embodiments, optionally, the expansion member 113 is made of a memory alloy material, and the expansion member 113 is configured to deform to extend or contract in the predetermined direction when the temperature changes. Specifically, when the camera module 10 needs to be switched from the first state to the second state, heat is transferred to the memory alloy material to raise the temperature of the memory alloy material, and the memory alloy material with the raised temperature stretches in a preset manner, so as to drive the first movable portion 1111 to be far away from the first bearing portion 1121. When the camera module 10 is required to be switched from the second state to the first state, the heat of the memory alloy material is absorbed, so that the temperature of the memory alloy material is reduced, and the memory alloy material with reduced temperature is shortened in a preset manner, so that the first movable portion 1111 is driven to approach the first bearing portion 1121.

Referring to fig. 11 and 12, in the above two embodiments, optionally, the expansion member 113 is corrugated to extend or shorten in the predetermined direction. When the camera module 10 is changed from the first state to the second state, the height of the expansion and contraction member 113 is reduced. When the camera module 10 is changed from the second state to the first state, the height of the expansion and contraction member 113 increases.

Specifically, the expansion member 113 includes a plurality of deformation portions 1131, and the deformation portions 1131 are sequentially connected along a predetermined direction, so as to form a corrugated shape. Each deformation portion 1131 is substantially V-shaped, and each deformation portion 1131 includes a first side wall 1131a and a second side wall 1131b, and adjacent first side wall 1131a and second side wall 1131b form an included angle α. It will be appreciated that, since the adjacent first and second sidewalls 1131a, 1131b form an included angle α, there is a space between the first and second sidewalls 1131a, 1131b that allows the adjacent first and second sidewalls 1131a, 1131b to move relative to each other, as a whole, in that the expansion member 113 can be extended or contracted in a predetermined direction. When the camera module 10 is switched from the first state to the second state, the telescopic member 113 is extended along the preset direction, the included angle α is gradually increased, and the undulating height of the telescopic member 113 is reduced. When the camera module 10 is switched from the second state to the first state, the telescopic member 113 is shortened along the preset direction, the included angle α is gradually reduced, and the undulating height of the telescopic member 113 is increased.

Further, a driving manner (including the following first, second and third embodiments) for moving the first movable portion 1111 in the predetermined direction will be described below with reference to the accompanying drawings.

Referring to fig. 13, in an embodiment, the camera module 10 further includes a driving component 16, the driving component 16 includes a piezoelectric body 161, and the piezoelectric body 161 is made of a piezoelectric material. The piezoelectric body 161 is abutted against the movable cover 111, and the piezoelectric body 161 is configured to drive the first movable portion 1111 to be far away from or close to the first bearing portion 1121 along the preset direction when being electrified.

The piezoelectric body 161 is a piezoelectric material having the following characteristics: when an electric field is applied to the polarization direction of the piezoelectric material, the piezoelectric material will deform, and when the electric field is removed, the deformation of the piezoelectric material disappears, namely the inverse piezoelectric effect of the piezoelectric material. Therefore, by utilizing the inverse piezoelectric effect of the piezoelectric material, the movable cover 111 can be driven to move by controlling the energization of the piezoelectric body 161.

Specifically, the piezoelectric body 161 is abutted against the movable cover 111, and the abutment means that a certain positive pressure exists between the piezoelectric body 161 and the movable cover 111, and the direction of the positive pressure and the preset direction can be mutually perpendicular. When the piezoelectric body 161 is energized, the piezoelectric body 161 is deformed at a high frequency, that is, is expressed as high-frequency vibration. Since there is a positive pressure between the piezoelectric body 161 and the movable cover 111, a frictional force will be generated between the two, and the frictional force will drive the movable cover 111 to displace. Each vibration of the piezoelectric body 161 can make the movable cover 111 generate a small displacement, and after a plurality of vibrations, the movable cover 111 can move by a large displacement.

It should be noted that, in the present embodiment, the driving assembly 16 is a fixed device, and does not move along with the movable cover 111. The driving assembly 16 may be fixed to the carrier body 112 or may be fixed to other components, which is not limited herein.

The piezoelectric body 161 may be made of piezoelectric ceramics or piezoelectric single crystals, or may be made of multilayer ceramics, and specifically, the piezoelectric body 161 may be made of lead zirconate titanate (PZT) -based piezoelectric ceramics, potassium sodium niobate (KNN) -based piezoelectric ceramics, barium Titanate (BT) -based piezoelectric ceramics, lead magnesium niobate-lead indium niobate (PMN-PT) -based piezoelectric single crystals, textured ceramics, or the like.

Optionally, the driving assembly 16 may further include a friction head 162, where the friction head 162 is fixedly connected to the piezoelectric body 161 and abuts against the movable cover 111, that is, the piezoelectric body 161 indirectly abuts against the movable cover 111 through the friction head 162. The piezoelectric body 161 drives the friction head 162 to move correspondingly when vibrating at high frequency, and the friction head 162 further drives the movable cover 111 to move along the preset direction through friction. The friction head 162 may be made of alumina (Al 2O 3), silica (SiO 2), zirconia (ZrO 2), carbon fiber, polyester fiber, aluminum, iron, copper, stainless steel, or other wear-resistant materials to ensure that the driving force of the driving component 16 can be well transmitted to the movable cover 111. The shape of the friction head 162 may be cylindrical, semi-cylindrical, spherical, triangular conical or some other irregular shape, and the surface of the friction head 162 abutting against the movable cover 111 may be chamfered or rounded. The number of the friction heads 162 may be one or a plurality.

Referring to fig. 13, the movable cover 111 further includes a second movable portion 1112, the second movable portion 1112 is bent and connected to the first movable portion 1111, and the first movable portion 1111 and the second movable portion 1112 move synchronously along a predetermined direction. In the process of switching the first state and the second state, the camera module 10 always contacts the friction head 162 with the second movable portion 1112. The friction head 162 drives the second movable portion 1112 to move along the preset direction through the friction, and since the second movable portion 1112 is fixedly connected to the first movable portion 1111, the movement of the second movable portion 1112 along the preset direction means that the first movable portion 1111 also moves along the preset direction. The second movable portion 1112 is described in the previous embodiment.

It will be appreciated that in some embodiments, the friction head 162 may also abut the first movable portion 1111 without the second movable portion 1112. However, this requires a large size of the first movable portion 1111 in the preset direction to ensure that the friction head 162 and the first movable portion 1111 always maintain the abutting relationship, however, a large size of the first movable portion 1111 in the preset direction increases the height of the camera module 10. In contrast, after the second movable portion 1112 is disposed, since the second movable portion 1112 is bent and connected to the first movable portion 1111, the second movable portion 1112 can be disposed in a larger size in the preset direction without increasing the height of the camera module 10, so that the second movable portion 1112 is beneficial to always abutting against the friction head 162.

Referring to fig. 14, in two embodiments, the camera module 10 further includes a driving assembly 16, and the driving assembly 16 includes a first magnetic member 163 and a second magnetic member 164 that can generate magnetic fields. The first magnetic member 163 is connected to the movable cover 111, and the second magnetic member 164 is connected to the carrying body 112. At least one of the first magnetic member 163 and the second magnetic member 164 is an electromagnet, so that the first magnetic member 163 and the second magnetic member 164 magnetically attract or repel each other when energized, so that the first movable portion 1111 approaches or departs from the first bearing portion 1121 along the predetermined direction.

In one embodiment, the first magnetic element 163 is an electromagnet, the second magnetic element 164 is a magnetic element (such as a magnet) with a magnetic substance, and when the camera module 10 is switched from the first state to the second state, the first magnetic element 163 is controlled to repel the second magnetic element 164 by electric control, and the first magnetic element 163 further drives the first movable portion 1111 to be far away from the first carrying portion 1121 along the preset direction. When the camera module 10 is switched from the second state to the first state, the first magnetic member 163 is controlled to magnetically attract the second magnetic member 164 by the electric control, and the first magnetic member 163 further drives the first movable portion 1111 to approach the first carrying portion 1121 along the preset direction.

In another embodiment, the first magnetic member 163 is a magnetic member (such as a magnet) having a magnetic substance, and the second magnetic member 164 is an electromagnet. When the camera module 10 is switched from the first state to the second state, the second magnetic member 164 is controlled by the electric control to repel the first magnetic member 163, and the first magnetic member 163 further drives the first movable portion 1111 to move away from the first carrying portion 1121 along the predetermined direction. When the camera module 10 is switched from the second state to the first state, the second magnetic member 164 is controlled to magnetically attract the first magnetic member 163 by the electric control, and the first magnetic member 163 further drives the first movable portion 1111 to approach the first carrying portion 1121 along the preset direction.

In yet another embodiment, the first magnetic member 163 and the second magnetic member 164 are both electromagnets. When the camera module 10 is switched from the first state to the second state, the first magnetic member 163 and the second magnetic member 164 are electrically controlled to repel each other, and the first magnetic member 163 further drives the first movable portion 1111 to move away from the first bearing portion 1121 along the predetermined direction. When the camera module 10 is switched from the second state to the first state, the first magnetic member 163 and the second magnetic member 164 are magnetically attracted to each other by the electric control, and the first magnetic member 163 further drives the first movable portion 1111 to approach the first carrying portion 1121 along the preset direction.

In the third embodiment, when the camera module 10 is changed from the first state to the second state, an end of the photosensitive assembly 12 away from the first bearing portion 1121 abuts against the first movable portion 1111, so that the first movable portion 1111 is away from the first bearing portion 1121 along a preset direction. That is, the driving force of the first movable portion 1111 away from the first carrier portion 1121 in the predetermined direction comes from the photosensitive member 12. Specifically, when the camera module 10 is changed from the first state to the second state, the height of the photosensitive element 12 in the preset direction increases, so as to abut against the first movable portion 1111, and then, as the height of the photosensitive element 12 increases, the first movable portion 1111 gradually moves away from the first carrier portion 1121. It can be appreciated that, in the form of this embodiment, no additional structure for driving the first movable portion 1111 is required, thereby facilitating miniaturization of the camera module 10.

Further optionally, when the camera module 10 is changed from the second state to the first state, the first movable portion 1111 automatically approaches the first carrying portion 1121. There are various ways of implementing the automatic approach of the first movable portion 1111 to the first carrier portion 1121, for example, the first movable portion 1111 and the carrier body 112 are connected by a spring, and when the camera module 10 is in the second state, the spring is elongated, and the elongated spring applies an elastic force toward the first carrier portion 1121 to the first movable portion 1111, so that the first movable portion 1111 may automatically approach the first carrier portion 1121. For another example, the first movable portion 1111 is provided with a first magnet, the carrier body 112 is provided with a second magnet, and the first magnet and the second magnet are always in a mutually attracted state, and when the camera module 10 is in the second state, the first movable portion 1111 will receive a force towards the first carrier portion 1121, so that the first movable portion 1111 can automatically approach the first carrier portion 1121.

The structural form of the first movable portion 1111 will be described with reference to the accompanying drawings.

Referring to fig. 15, in one embodiment, the first movable portion 1111 includes a first sub-portion 1111a and a second sub-portion 1111b that are movably connected. The first sub-portion 1111a has a light transmitting portion T, and the light transmitting portion T is transparent to light. The first sub-portion 1111a is fixedly connected to the carrier body 112, i.e. the first sub-portion 1111a cannot move relative to the first carrier portion 1121. The second sub-portion 1111b is opaque, and the second sub-portion 1111b may be far from or near to the first carrying portion 1121 along a predetermined direction. The orthographic projection of the photosensitive element 12 on the second sub-portion 1111b falls within the range of the second sub-portion 1111b, that is, the second sub-portion 1111b is disposed opposite to the photosensitive element 12, which is used to provide enough space for the movement of the photosensitive element 12. In the present embodiment, the first sub-portion 1111a does not move, and only the second sub-portion 1111b is movable, so that the driving force for driving the first movable portion 1111 can be reduced, thereby reducing the power consumption.

Referring to fig. 16, in another embodiment, the first movable portion 1111 includes a first sub-portion 1111a and a second sub-portion 1111b that are fixedly connected, the first sub-portion 1111a has a light-transmitting portion T, and the first sub-portion 1111a and the second sub-portion 1111b may be far from or near to the first bearing portion 1121 along a predetermined direction. That is, the first sub-portion 1111a and the second sub-portion 1111b are connected together and move synchronously. By the arrangement, the structure can be simplified, and processing, manufacturing, assembling and the like are easier.
