[0002] With the rapid iteration of electronic devices and the continuous upgrading of consumer market demands, electronic devices are gradually developing towards thinner, lighter, more integrated, and more multifunctional designs. However, electronic devices often integrate various functional modules such as camera modules, speaker modules, battery modules, and circuit boards, occupying a large amount of internal space and hindering the miniaturization design of electronic devices. Summary of the Invention

[0003] This application provides a camera module and an electronic device for saving internal space in electronic devices, thereby facilitating the miniaturization of electronic devices.

[0004] In a first aspect, this application provides a camera module, including a housing, a first light-shielding member, a second light-shielding member, a first dimming member, and a photosensitive component. The housing is provided with a mounting cavity, a first light-transmitting hole, and a second light-transmitting hole. The mounting cavity is located inside the housing. The first light-transmitting hole and the second light-transmitting hole penetrate the outer surface of the housing and the cavity wall of the mounting cavity, and are spaced apart from each other. The first light-shielding member and the second light-shielding member are both mounted on the housing. The first dimming member is mounted on the mounting cavity. The photosensitive component is mounted on the housing. The camera module has a first state and a second state. When the camera module is in the first state, the first light-shielding member opens the first light-transmitting hole, the second light-shielding member closes the second light-transmitting hole, and the first dimming member is used to adjust the light incident from the first light-transmitting hole to the photosensitive component.

[0005] When the camera module described in this application is used in an electronic device, the cooperation between the first light-shielding member, the second light-shielding member, and the first dimming member enables the camera module to be used simultaneously as a front-facing camera module and a rear-facing camera module. By using the camera module, the electronic device can simultaneously achieve front-facing and rear-facing camera functions, which can save on the functional modules included in the electronic device. This not only saves on the material cost of the electronic device but also saves on the internal space of the electronic device, contributing to the miniaturization design of the electronic device.

[0006] Moreover, the electronic device only needs to use one camera module to realize front and rear camera functions.

The second reflective surface is connected between the second light-inlet surface and the second light-outlet surface and is used to emit light incident from the second light-inlet surface to the second light-outlet surface.

[0022] The first dimming element, by using the first sub-dimming element and the second sub-dimming element, can eliminate the need for the first driving element and the third conductive element. The first dimming element can achieve the front and rear dual-camera function without rotation, which can simplify the structure of the camera module and improve the reliability of the camera module.

Detailed Implementation

[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the first electronic device 1 provided in this application. Figure 2yes Figure 1 The schematic diagram of the electronic device 1 shown is viewed from another angle.

[0042] Electronic device 1 can be a mobile phone, tablet computer, laptop computer, in-vehicle infotainment system, smartwatch, smart bracelet, POS machine (point of sales terminal), or other electronic products. In the following description, this application will use a mobile phone as an example. For ease of description, the width direction of electronic device 1 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. The X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0043] In this embodiment, electronic device 1 is a candybar mobile phone. Electronic device 1 includes a housing 10, a first display module 20, a circuit board 30, a processor 40, and a camera module 50. The first display module 20, circuit board 30, processor 40, and camera module 50 are all mounted on the housing 10. The first display module 20 and camera module 50 are both electrically connected to the processor 40.

[0044] The housing 10 has a second light-transmitting area 101, through which ambient light can enter the inner side of the housing 10. For example, the second light-transmitting area 101 is a through hole, connecting the inner and outer sides of the housing 10. The housing 10 includes a middle frame 11 and a rear cover 12. The rear cover 12 is mounted on one side of the middle frame 11 along its thickness direction (Z-axis direction in the figure). The rear cover 12 has a second light-transmitting area 101 that extends through the rear cover 12 along its thickness direction (Z-axis direction in the figure).

[0045] The first display module 20 is mounted on the side of the mid-frame 11 facing away from the back cover 12. When the user uses the electronic device 1, the first display module 20 faces the user, and the back cover 12 faces away from the user. The first display module 20 has a first light-transmitting area 201, through which ambient light can enter the inner side of the housing 10. Along the thickness direction of the electronic device 1 (Z-axis direction in the figure), the first light-transmitting area 201 and the second light-transmitting area 101 are arranged opposite to each other. The first display module 20 may include a cover plate and a display screen (not shown) fixed to the cover plate. The cover plate may be made of transparent materials such as glass. The display screen may be an LCD (liquid crystal display) or an OLED (organic light-emitting diode) display screen, used to display information such as images or text.

[0046] In one embodiment, the first light-transmitting area 201 may be a through-hole, extending through the first display module 20 along its thickness direction (Z-axis direction in the figure). Alternatively, the first light-transmitting area 201 may not be a through-hole, but rather a transparent portion of the first display module 20 that allows light to pass through. It should be noted that when the size of the first light-transmitting area 201 is small, it may be a through-hole; conversely, when the size of the first light-transmitting area 201 is large, it may be a transparent portion of the first display module 20. This is to avoid affecting the screen-to-body ratio and display effect of the first display module 20 due to an excessively large cutout in the first display module 20, thereby improving the user experience.

[0047] The circuit board 30, processor 40, and camera module 50 are all mounted inside the housing 10. Specifically, the circuit board 30, processor 40, and camera module 50 are all mounted inside the middle frame 11. The processor 40 is mounted on the circuit board 30 and electrically connected to it. The circuit board 30 can be the main board of the electronic device 1, and the processor 40 can be the CPU (central processing unit) of the electronic device 1.

[0048] Along the thickness direction of the electronic device 1, the camera module 50 is located between the second light-transmitting area 101 and the first light-transmitting area 201, and is positioned opposite to both the second light-transmitting area 101 and the first light-transmitting area 201, and is electrically connected to the circuit board 30. The camera module 50 can be electrically connected to the processor 40 via the circuit board 30. The camera module 50 can receive information acquisition signals sent by the processor 40 via the circuit board 30, and acquire ambient light through the second light-transmitting area 101 or the first light-transmitting area 201 to form corresponding image data. When the camera module 50 acquires ambient light through the first light-transmitting area 201, the camera module 50 acts as a front-facing camera module of the electronic device 1; when the camera module 50 acquires ambient light through the second light-transmitting area 101, the camera module 50 acts as a rear-facing camera module of the electronic device 1. It is understandable that when the first light-transmitting area 201 is the part of the first display module 20 that can transmit light, and the camera module 50 is the front camera module of the electronic device 1, the camera module 50 can be the under-screen camera module of the electronic device 1.

[0049] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 1 A schematic diagram of the structure of the first camera module 50 in the electronic device 1 shown. Figure 4 yes Figure 3 The diagram shows the structure of the camera module 50 after being cut along point II. Here, "cut along point II" refers to cutting along the plane containing line II; other similar descriptions in this document can be understood in the same way.

[0050] In this embodiment, the width direction of the camera module 50 is parallel to the X-axis direction, the length direction of the camera module 50 is parallel to the Y-axis direction, and the thickness direction of the camera module 50 is parallel to the Z-axis direction. In some other embodiments, the width direction of the camera module 50 may also be parallel to the Y-axis direction, and the length direction of the camera module 50 may also be parallel to the X-axis direction; this application does not impose specific limitations on this.

The first light-shielding member 52, the second light-shielding member 53, the dimming bracket 54, the first driving member 55, the first dimming member 56, the lens 57, the lens bracket 58, the second driving member, and the photosensitive component 59 are all mounted on the housing 51. The first light-shielding member 52, the second light-shielding member 53, the first driving member 55, and the second driving member are all electrically connected to the photosensitive component 59, and the photosensitive component 59 is electrically connected to the processor 40. For example, the photosensitive component 59 is electrically connected to the circuit board 30, and the circuit board 30 enables the electrical connection between the photosensitive component 59 and the processor 40.

[0052] Please refer to the following: Figures 5 to 7 , Figure 5 yes Figure 3 A schematic diagram of the structure of the outer casing 51 in the camera module 50 is shown.

Along the width direction of the housing 51 (X-axis direction in the diagram), the third side face 5115 and the fourth side face 5116 are arranged opposite to each other and connected between the first end face 5111 and the second end face 5112, and between the first side face 5113 and the second side face 5114.

The first cavity wall surface 5122 is disposed opposite to the opening of the mounting cavity 512. Along the thickness direction of the mounting cavity 512 (Z-axis direction in the figure), the second cavity wall surface 5123 and the third cavity wall surface 5124 are disposed opposite to each other and are respectively connected to opposite sides of the first cavity wall surface 5122.

[0055] The first light-transmitting hole 513 and the second light-transmitting hole 514 penetrate the outer surface 511 of the housing 51 and the cavity wall 5121 of the mounting cavity 512, and connect the mounting cavity 512 and the outside of the housing 51. Along the thickness direction of the housing 51 (Z-axis direction in the figure), the first light-transmitting hole 513 and the second light-transmitting hole 514 are spaced apart and opposite to each other.

There are two of each type of first sliding portion 515 and first limiting portion 516. The two first sliding portions 515 are located on the third cavity wall surface 5124 and are spaced apart along the X-axis. One first limiting portion 516 is located on the fourth cavity wall surface 5125, and the other first limiting portion 516 is located on the fifth cavity wall surface 5126.

[0057] In this embodiment, both the first sliding portion 515 and the first limiting portion 516 are protrusions, and both protrude from the cavity wall surface 5121 of the mounting cavity 512 toward the mounting cavity 512. Specifically, the first sliding portion 515 protrudes from the third cavity wall surface 5124 toward the mounting cavity 512 (positive Z-axis direction in the figure). For example, the first sliding portion 515 is elongated, and its length direction is parallel to the Y-axis direction. The first sliding portion 515 is provided with a sliding groove 5151, the opening of which is located on the surface of the first sliding portion 515 away from the third cavity wall surface 5124. The sliding groove 5151 is recessed from the surface of the first sliding portion 515 away from the third cavity wall surface 5124 toward the third cavity wall surface 5124 (negative Z-axis direction in the figure). For example, the sliding groove 5151 is a strip-shaped groove, and its length direction is parallel to the Y-axis direction.

[0058] One first limiting portion 516 protrudes from the fourth cavity wall surface 5125 toward the mounting cavity 512 (negative X-axis direction in the figure), and another first limiting portion 516 protrudes from the fifth cavity wall surface 5126 toward the mounting cavity 512 (positive X-axis direction in the figure). Each first limiting portion 516 is spaced apart from and opposite to a first sliding portion 515 along the thickness direction of the mounting cavity 512.

[0059] Please see Figure 4 The first light-shielding component 52, the second light-shielding component 53, the dimming bracket 54, the first driving component 55, the first dimming component 56, the lens 57, the lens bracket 58, and the second driving component are all installed in the mounting cavity 512. Specifically, the first light-shielding component 52 and the second light-shielding component 53 are both installed on the cavity wall 5121 of the mounting cavity 512. Among them, the first light-shielding component 52 is installed on the second cavity wall 5123, and the second light-shielding component 53 is installed on the third cavity wall 5124. When the first light-shielding component 52 opens the first light-transmitting hole 513, the first light-shielding component 52 and the first light-transmitting hole 513 are misaligned, and the first light-transmitting hole 513 is exposed. The first light-transmitting hole 513 connects the mounting cavity 512 and the outside of the outer shell 51, and ambient light can enter the mounting cavity 512 through the first light-transmitting area 201 and the first light-transmitting hole 513. When the first light-shielding member 52 closes the first light-transmitting hole 513, the first light-shielding member 52 covers the first light-transmitting hole 513 to block the mounting cavity 512 and the first light-transmitting hole 513, which can prevent excess ambient light from entering the mounting cavity 512 through the first light-transmitting hole 513 and interfering with the subsequent imaging.

[0060] When the second light-shielding member 53 opens the second light-transmitting hole 514, the second light-shielding member 53 is misaligned with the second light-transmitting hole 514, exposing the second light-transmitting hole 514. The second light-transmitting hole 514 connects the mounting cavity 512 and the outside of the outer casing 51, allowing ambient light to enter the mounting cavity 512 through the second light-transmitting area 101 and the first light-transmitting hole 513. When the second light-shielding member 53 closes the second light-transmitting hole 514, the second light-shielding member 53 covers the second light-transmitting hole 514, blocking the mounting cavity 512 and the second light-transmitting hole 514, thus preventing excess ambient light from entering the mounting cavity 512 through the second light-transmitting hole 514 and interfering with the front-facing camera imaging.

[0061] In some other embodiments, the first light-shielding member 52 and the second light-shielding member 53 may also be installed on the outer surface 511 of the housing 51. In this case, the first light-shielding member 52 may be installed on the first side 5113 and the second light-shielding member 53 may be installed on the second side 5114. Alternatively, one of the first light-shielding member 52 and the second light-shielding member 53 may be installed in the mounting cavity 512 and the other may be installed on the outer surface 511 of the housing 51. This application does not impose any specific limitations on this.

[0062] The first light-shielding element 52 and the second light-shielding element 53 are made of shape memory materials. Specifically, the first light-shielding element 52 and the second light-shielding element 53 are made of shape memory alloys (SMA) or shape memory polymers (SMPCs). Among them, the first light-shielding element 52 and the second light-shielding element 53 can be made of black-plated shape memory alloys to ensure the light-shielding effect of the first light-shielding element 52 and the second light-shielding element 53.

[0063] In this embodiment, the first light-shielding member 52 and the second light-shielding member 53 can deform under the action of an electric current to switch between opening and closing the light-transmitting hole. For example, switching between opening and closing the light-transmitting hole can be achieved by passing different magnitudes of current through the first light-shielding member 52 and the second light-shielding member 53. In other embodiments, the first light-shielding member 52 and the second light-shielding member 53 can deform under physical stimuli such as light or magnetism; or, one of the first light-shielding member 52 and the second light-shielding member 53 may be made of a shape memory material and deform under physical stimuli such as electricity, light, or magnetism to achieve switching between opening and closing the light-transmitting hole, while the other uses other methods to achieve switching between opening and closing the light-transmitting hole. This application does not impose specific limitations on these methods.

[0064] In addition, the camera module 50 also includes a first conductive element 50a and a second conductive element 50b, both of which are embedded in the housing 51 and spaced apart from each other. Specifically, the first conductive element 50a is electrically connected between the first light-shielding element 52 and the photosensitive element 59 to achieve signal transmission between them. The second conductive element 50b is electrically connected between the second light-shielding element 53 and the photosensitive element 59 to achieve signal transmission between them. Both the first conductive element 50a and the second conductive element 50b can be made of metal. For example, both the first conductive element 50a and the second conductive element 50b can be embedded in the housing 51 by in-mold injection molding.

[0065] Please refer to the following: Figure 4 and Figure 8 , Figure 8 yes Figure 3 A schematic diagram of the structure of the dimming bracket 54, the first driving component 55, and the first dimming component 56 in the camera module 50 shown.

[0066] The dimming bracket 54 is spaced apart from the cavity wall 5121 of the mounting cavity 512 and is located between the first light-transmitting hole 513 and the second light-transmitting hole 514, and is rotatable relative to the outer shell 51. For example, the axis of rotation of the dimming bracket 54 relative to the outer shell 51 is parallel to the X-axis direction. The dimming bracket 54 has a third end face 541, a fourth end face 542, and a peripheral side face 543. Along the thickness direction of the dimming bracket 54 (the X-axis direction in the figure), the third end face 541 and the fourth end face 542 are arranged opposite to each other. The third end face 541 faces the fourth cavity wall 5125, and the fourth end face 542 faces the fifth cavity wall 5126. The peripheral side face 543 surrounds the dimming bracket 54 and connects between the third end face 541 and the fourth end face 542. The dimming bracket 54 is provided with a mounting groove 544, the opening of which is located on the peripheral side face 543. The mounting groove 544 is recessed from the peripheral side 543 toward the rotation axis of the dimming bracket 54, and is spaced apart from the third end face 541 and the fourth end face 542.

[0067] A first drive element 55 is mounted on a dimming bracket 54 and is used to drive the dimming bracket 54 to rotate relative to the housing 51. Exemplarily, the first drive element 55 may be a brushless direct current motor (BLDC). In this embodiment, the first drive element 55 has a first position and a second position. When the first drive element 55 is adjusted to the first position, it drives the dimming bracket 54 to rotate 90 degrees clockwise relative to the housing 51. When the first drive element 55 is adjusted to the second position, it drives the dimming bracket 54 to rotate 90 degrees counterclockwise relative to the housing 51. At this time, the first drive element 55 can use an open-loop control mode to save on the cost of the camera module 50. In some other embodiments, the first drive element 55 can use a closed-loop control mode to achieve precise control of the first drive element 55.

[0068] The first driving component 55 includes a drive shaft 551 and a drive housing 552. The drive shaft 551 passes through the dimming bracket 54 and is fixedly installed in the mounting cavity 512. Specifically, one end of the drive shaft 551 is fixedly installed on the second cavity wall 5123, and the other end is fixedly installed on the third cavity wall 5124. The axis of the drive shaft 551 coincides with the rotation axis of the dimming bracket 54 relative to the housing 51.

[0069] A drive housing 552 is sleeved on the drive shaft 551 and can rotate relative to the drive shaft 551, and is fixedly installed on the dimming bracket 54. The axis of rotation of the drive housing 552 relative to the drive shaft 551 coincides with the axis of the drive shaft 551. In this embodiment, there are two drive housings 552, which are respectively fixedly installed on the third end face 541 and the fourth end face 542. When the drive housing 552 rotates relative to the drive shaft 551, it can drive the dimming bracket 54 to rotate relative to the drive shaft 551, thereby realizing the rotation of the dimming bracket 54 relative to the housing 51.

[0070] In addition, the camera module 50 also includes a third conductive element 50c, which is embedded in the housing 51 and spaced apart from the first conductive element 50a and the second conductive element 50b. Specifically, the third conductive element 50c is electrically connected between the first driving element 55 and the photosensitive element 59 to realize signal transmission between the first driving element 55 and the photosensitive element 59. For example, a signal trace may be provided in the drive shaft 551, and the third conductive element 50c may be electrically connected to the signal trace in the drive shaft 551 to realize the power supply and control signal transmission of the first driving element 55. The third conductive element 50c may be made of metal. For example, the third conductive element 50c may be embedded in the housing 51 by in-mold injection molding.

[0071] The first dimming element 56 is located between the first light-transmitting hole 513 and the second light-transmitting hole 514, and is disposed opposite to the first light-transmitting hole 513 and the second light-transmitting hole 514, and can rotate relative to the outer shell 51. The rotation axis of the dimming bracket 54 relative to the outer shell 51 coincides with the rotation axis of the dimming bracket 54 relative to the outer shell 51. In this embodiment, the first dimming element 56 is mounted on the dimming bracket 54 and can rotate relative to the outer shell 51 under the drive of the dimming bracket 54. Specifically, the first dimming element 56 is mounted in the mounting groove 544. The first dimming element 56 can be mounted in the mounting groove 544 by means of adhesive bonding or other methods.

[0072] The first dimming element 56 has a light-inlet surface (not shown), a light-outlet surface (not shown), and a reflective surface 563. The reflective surface 563 is connected between the light-inlet surface and the light-outlet surface and is used to reflect light incident from the light-inlet surface to the light-outlet surface. In this embodiment, the first dimming element 56 includes a refractive prism 56a, which has a first surface 564, a second surface 565, and a reflective surface 563. The second surface 565 is connected to and intersects with the first surface 564. For example, the second surface 565 and the first surface 564 are perpendicular to each other. The reflective surface 563 is connected between the first surface 564 and the second surface 565. The first surface 564 and the second surface 565 are exposed relative to the dimming bracket 54, and the reflective surface 563 is disposed opposite to the bottom wall surface 5441 of the mounting groove 544.

[0073] Please refer to the following: Figure 4 and Figure 9 , Figure 9 yes Figure 3 A schematic diagram of the lens bracket 58 in the camera module 50 shown.

[0074] Lens 57 and lens bracket 58 are located on the side of the first dimming element 56 opposite to the dimming bracket 54. Lens 57 is spaced apart from and opposite to the first dimming element 56, and can move relative to the first dimming element 56 along the optical axis of lens 57 to achieve focusing of camera module 50. The optical axis of lens 57 is parallel to the Y-axis. Lens bracket 58 is fitted onto lens 57 and can move relative to the first dimming element 56 along the optical axis of lens 57, thereby causing lens 57 to move relative to the first dimming element 56 along the optical axis of lens 57.

[0075] The lens support 58 is provided with a second sliding part 581 and a second limiting part 582. Both the second sliding part 581 and the second limiting part 582 are provided on the surface of the lens support 58 away from the lens 57 and are spaced apart from each other. There are two of each of the second sliding part 581 and the second limiting part 582. Along the X-axis, the two second sliding parts 581 are spaced apart, and the two second limiting parts 582 are respectively provided on opposite sides of the lens support 58.

[0076] In this embodiment, both the second sliding portion 581 and the second limiting portion 582 are protrusions. The second sliding portion 581 extends from the surface of the lens bracket 58 away from the lens 57 toward the first sliding portion 515 and slides in engagement with the first sliding portion 515. Specifically, the second sliding portion 581 is inserted into the sliding groove 5151 and can move relative to the first sliding portion 515 along the optical axis of the lens 57 within the sliding groove 5151 to achieve a sliding engagement between the second sliding portion 581 and the first sliding portion 515. In some other embodiments, the second sliding portion 581 may also be provided with a sliding groove, and the first sliding portion 515 may be inserted into the sliding groove and can move relative to the second sliding portion 581 along the optical axis of the lens 57 within the sliding groove to achieve a sliding engagement between the second sliding portion 581 and the first sliding portion 515. This application does not impose specific limitations on this.

[0077] The second limiting part 582 extends from the surface of the lens bracket 58 away from the lens 57 toward the first limiting part 516, and mutually limits the first limiting part 516. Specifically, the second limiting part 582 is located on the side of the second sliding part 581 away from the third cavity wall 5124, and on the side of the first limiting part 516 away from the second cavity wall 4123, and abuts against the first limiting part 516. The mutual cooperation of the first limiting part 516 and the second limiting part 582 can limit the position of the lens 57 and the lens bracket 58 in the mounting cavity 512, ensuring the assembly stability of the lens 57 and the lens bracket 58 in the mounting cavity 512.

[0078] The second driving member can be installed in the mounting cavity 512 and connected to the lens bracket 58, and is used to drive the lens bracket 58 to move relative to the housing 51 along the optical axis of the lens 57. In addition, the camera module 50 also includes a fourth conductive member 50d, which is embedded in the housing 51, and the first conductive member 50a, the second conductive member 50b, and the third conductive member 50c are all spaced apart. Specifically, the fourth conductive member 50d is electrically connected between the second driving member and the photosensitive component 59 to realize signal transmission between the second driving member and the photosensitive component 59. The fourth conductive member 50d can be made of metal. For example, the fourth conductive member 50d can be embedded in the housing 51 by in-mold injection molding.

[0079] It should be noted that the camera module 50 can also be a camera module with autofocus (AF) function, or it can be a camera module with autofocus and optical image stabilization (OIS) function. In this case, the camera module 50 may include an optical image stabilization mechanism, which works in conjunction with the first dimming element 56 to realize the optical image stabilization function of the camera module 50. Alternatively, the camera module 50 can also be a fixed focus (FF) camera module. The implementation methods of fixed focus, autofocus and optical image stabilization of the camera module 50 can refer to the implementation methods of existing camera modules, and will not be described in detail here.

[0080] Please see Figure 4 and Figure 10 , Figure 10 yes Figure 4 A schematic diagram of the structure of the photosensitive component 59 in the camera module 50 shown.

[0081] The photosensitive component 59 is located on the side of the lens 57 and lens holder 58 facing away from the first dimming element 56, and is disposed opposite to the lens 57. At this time, both the lens 57 and lens holder 58 are located between the first dimming element 56 and the photosensitive component 59. Specifically, the photosensitive component 59 is mounted on the second end face 5112 and covers the opening of the mounting cavity 512. In this embodiment, the photosensitive component 59 includes a photosensitive circuit board 591, a photosensitive sensor 592, a photosensitive holder 593, and a filter 594. The photosensitive circuit board 591 is electrically connected to the circuit board 30 and the processor 40, and is also electrically connected to the first conductive element 50a, the second conductive element 50b, the third conductive element 50c, and the fourth conductive element 50d. The photosensitive circuit board 591 can be electrically connected to the processor 40 through the circuit board 30. For example, the photosensitive circuit board 591 can be a rigid-flex circuit board.

[0082] A photosensor 592 is mounted on the side of the photosensor circuit board 591 facing the first dimming element 56 and the lens 57, and is electrically connected to the photosensor circuit board 591. The photosensor 592 can collect ambient light passing through the first dimming element 56 and the lens 57, generate a signal based on the ambient light, and transmit the signal to the circuit board 30 of the electronic device 1 via the photosensor circuit board 591. For example, the photosensor 592 can be a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor. A photosensor bracket 593 is mounted on the side of the photosensor circuit board 591 facing the first dimming element 56 and the lens 57, and covers the photosensor 592. The photosensor bracket 593 has a filter aperture 5931, which extends through the photosensor bracket 593 along its thickness direction (Y-axis direction in the figure) and is positioned opposite to the photosensor 592. The filter 594 is mounted on the photosensitive holder 593 and covers the filter hole 5931.

[0083] Please refer to the following: Figure 11 and Figure 12 , Figure 11 yes Figure 4 The diagram shows the structure of the camera module 50 in its first state. Figure 12 yes Figure 11 The diagram shows the structure of the camera module 50 in its second state. Figure 11 and Figure 12 The propagation path of ambient light L is illustrated using a dotted line with an arrow.

[0084] The camera module 50 has a first state and a second state. For example... Figure 11As shown, when the camera module 50 is in the first state, the first light-blocking member 52 opens the first light-transmitting hole 513, which is opposite to the first light-transmitting area 201 and communicates with the mounting cavity 512. The second light-blocking member 53 closes the second light-transmitting hole 514, which communicates with the second light-transmitting area 101 and is isolated from the mounting cavity 512. The light-inlet surface 561 of the first dimming member 56 faces the first light-transmitting hole 513 and is opposite to it, while the light-outlet surface 562 faces the lens 57 and the photosensitive component 59 and is opposite to it. The first dimming member 56 adjusts the light incident from the first light-transmitting hole 513 to the lens 57 and the photosensitive component 59. The first surface 564 of the refracting prism 56a serves as the light-inlet surface 561, and the second surface 565 serves as the light-outlet surface 562. For example, the ambient light L is perpendicular to the light-inlet surface 561. Ambient light L can pass through the first light-transmitting area 201 and enter the mounting cavity 512 through the first light-transmitting hole 513. It then enters the first dimming element 56 through the first surface 564. The reflecting surface 563 reflects the light entering the first dimming element 56 from the first surface 564 to the second surface 565. The light exiting the second surface 565 passes through the lens 57 and the filter 594 to reach the photosensor 592. The photosensor 592 generates a signal based on the ambient light and transmits the signal via the photosensor circuit board 591 to the circuit board 30 of the electronic device 1 to form an image. At this time, the electronic device 1 is in front-facing mode, and the camera module 50 can be used as the front-facing camera module of the electronic device 1. The second light-shielding element 53 prevents light from entering the mounting cavity 512 through the second light-transmitting hole 514, preventing light entering the mounting cavity 512 through the second light-transmitting hole 514 from interfering with imaging and ensuring the imaging effect of the camera module 50.

[0085] like Figure 12As shown, when the camera module 50 is in the second state, the first light-blocking member 52 closes the first light-transmitting hole 513, which is opposite to the first light-transmitting area 201 and isolated from the mounting cavity 512. The second light-blocking member 53 opens the second light-transmitting hole 514, which is connected to the second light-transmitting area 101 and the mounting cavity 512. The light-inlet surface 561 of the first dimming member 56 faces the second light-transmitting hole 514 and is opposite to it, while the light-outlet surface 562 faces the lens 57 and the photosensitive component 59 and is opposite to it. The first dimming member 56 adjusts the light incident from the second light-transmitting hole 514 to the lens 57 and the photosensitive component 59. The second surface 565 of the refracting prism 56a serves as the light-inlet surface 561, and the first surface 564 serves as the light-outlet surface 562. For example, the ambient light L is perpendicular to the light-inlet surface 561. Ambient light L can pass through the second light-transmitting area 101 and enter the mounting cavity 512 through the second light-transmitting hole 514. It then enters the first dimming element 56 through the second surface 565. The reflecting surface 563 reflects the light entering the first dimming element 56 from the second surface 565 back to the first surface 564. The light exiting the first surface 564 passes through the lens 57 and the filter 594 to reach the photosensor 592. The photosensor 592 generates a signal based on the ambient light and transmits the signal via the photosensor circuit board 591 to the circuit board 30 of the electronic device 1 to form an image. At this time, the electronic device 1 is in rear-facing mode, and the camera module 50 can be used as a rear-facing camera module of the electronic device 1. The first light-shielding element 52 prevents light from entering the mounting cavity 512 through the first light-transmitting hole 513, preventing light entering the mounting cavity 512 through the first light-transmitting hole 513 from interfering with imaging and ensuring the imaging effect of the camera module 50.

[0086] When the camera module 50 switches from the first state to the second state, both the first light-blocking member 52 and the second light-blocking member 53 can receive electrical signals sent by the processor 40 through the photosensitive circuit board 591. The first light-blocking member 52 can deform according to the electrical signal to switch from opening the first light-transmitting hole 513 to closing the first light-transmitting hole 513. The second light-blocking member 53 can deform according to the electrical signal to switch from closing the second light-transmitting hole 514 to opening the second light-transmitting hole 514. The first driving member 55 can receive the driving signal sent by the processor 40 through the photosensitive circuit board 591, and drive the dimming bracket 54 to rotate 90 degrees clockwise according to the driving signal, so as to drive the first dimming member 56 to rotate 90 degrees clockwise.

[0087] When the camera module 50 switches from the second state to the first state, both the first light-blocking member 52 and the second light-blocking member 53 can receive electrical signals sent by the processor 40 through the photosensitive circuit board 591. The first light-blocking member 52 can deform according to the electrical signal to switch from closing the first light-transmitting hole 513 to opening the first light-transmitting hole 513. The second light-blocking member 53 can deform according to the electrical signal to switch from opening the second light-transmitting hole 514 to closing the second light-transmitting hole 514. The first driving member 55 can receive the driving signal sent by the processor 40 through the photosensitive circuit board 591, and drive the dimming bracket 54 to rotate 90 degrees counterclockwise according to the driving signal, so as to drive the first dimming member 56 to rotate 90 degrees counterclockwise.

[0088] In the electronic device 1 shown in this application, the camera module 50 includes a first light-shielding member 52, a second light-shielding member 53, and a first dimming member 56. The cooperation between the first light-shielding member 52, the second light-shielding member 53, and the first dimming member 56 enables the camera module 50 to be used as both a front-facing camera module and a rear-facing camera module. In other words, the electronic device 1 only needs to use one camera module 50 to achieve both front-facing and rear-facing camera functions, which can save on the functional modules included in the electronic device 1. This not only saves on the material cost of the electronic device 1 but also saves on the internal space of the electronic device 1, which helps to achieve the miniaturization design of the electronic device 1.

[0089] Moreover, the electronic device 1 only needs to use a lens 57 and a photosensitive component 59 to realize the front and rear camera functions. Therefore, the electronic device 1 can realize front shooting by using a high-performance rear camera module without adding other materials, which can significantly improve the front shooting effect of the electronic device 1 and improve the user experience.

[0090] Please see Figure 13 and Figure 14 , Figure 13 yes Figure 1 The diagram shows the structure of the second camera module 50 in the first state in the electronic device 1 shown. Figure 14 yes Figure 13 The diagram shows the structure of the camera module 50 in its second state. Figure 13 and Figure 14 The propagation path of ambient light L is illustrated using a dotted line with an arrow.

[0091] The difference between the camera module 50 shown in this embodiment and the first type of camera module 50 described above is that the camera module 50 further includes a condenser lens 50e, which is disposed on the light-emitting surface 562 of the first dimming element 56. In this embodiment, there are two condenser lenses 50e, namely a first condenser lens 50f and a second condenser lens 50g. The first condenser lens 50f is disposed on the first surface 564, and the second condenser lens 50g is disposed on the second surface 565. At this time, the first dimming element 56 (refractive prism 56a), the first condenser lens 50f, and the second condenser lens 50g can be combined to form a condenser prism. The first dimming element 56, the first condenser lens 50f, and the second condenser lens 50g can be integrally molded, which not only saves material costs for the camera module 50 but also reduces the size of the camera module 50.

[0092] like Figure 13 As shown, when the camera module 50 is in the first state, the first condenser lens 50f faces the first light-transmitting hole 513 and is positioned opposite to it, while the second condenser lens 50g faces the photosensitive component 59 and is positioned opposite to it. At this time, ambient light L can pass through the first light-transmitting area 201 and enter the mounting cavity 512 through the first light-transmitting hole 513, passing through the first condenser lens 50f and entering the first dimming element 56. Light emitted from the second surface 565 passes through the second condenser lens 50g and the filter 594 to reach the photosensitive sensor 592. The photosensitive sensor 592 generates a signal based on the ambient light and transmits the signal via the photosensitive circuit board 591 to the circuit board 30 of the electronic device 1 to form an image. At this time, the first condenser lens 50f can converge the ambient light L.

[0093] like Figure 14 As shown, when the camera module 50 is in the second state, the second condenser lens 50g faces the first light-transmitting hole 513 and is positioned opposite to it, while the first condenser lens 50f faces the photosensitive component 59 and is positioned opposite to it. At this time, ambient light L can pass through the first light-transmitting area 201 and enter the mounting cavity 512 through the second light-transmitting hole 514, then pass through the second condenser lens 50g and enter the first dimming element 56. Light emitted from the first surface 564 passes through the first condenser lens 50f and the filter 594 to reach the photosensitive sensor 592. The photosensitive sensor 592 generates a signal based on the ambient light and transmits the signal via the photosensitive circuit board 591 to the circuit board 30 of the electronic device 1 to form an image. At this time, the second condenser lens 50g can converge the ambient light L.

[0094] In the camera module 50 shown in this embodiment, the camera module 50 uses a first dimming element 56, a first condenser lens 50f, and a second condenser lens 50g to refract and converge light. The camera module 50 can eliminate the need for a lens 57 and a lens bracket 58, which not only saves on the material cost of the camera module 50, but also reduces the size of the camera module 50, which helps to achieve the miniaturization design of the electronic device 1.

[0095] Please see Figure 15 and Figure 16 , Figure 15 yes Figure 1 The diagram shows the structure of the third camera module 50 in the first state in the electronic device 1 shown. Figure 16 yes Figure 15 The diagram shows the structure of the camera module 50 in its second state. Figure 15 and Figure 16 The propagation path of ambient light L is illustrated using a dotted line with an arrow.

[0096] The difference between the camera module 50 shown in this embodiment and the first type of camera module 50 described above is that the first dimming element 56 includes a reflector 56b, and the reflector 56b has a reflective surface 563. For example... Figure 15 As shown, when the camera module 50 is in the first state, the reflective surface 563 faces the first light-transmitting hole 513, the lens 57, and the photosensitive component 59, and is positioned opposite to the first light-transmitting hole 513 and the lens 57. The reflective surface 563 reflects the light incident from the first light-transmitting hole 513 to the lens 57 and the photosensitive component 59. Ambient light L can pass through the first light-transmitting area 201 and enter the mounting cavity 512 through the first light-transmitting hole 513. The reflective surface 563 reflects the light, and the light reflected by the reflective surface 563 passes through the lens 57 and the filter 594 to reach the photosensitive sensor 592. The photosensitive sensor 592 generates a signal based on the ambient light and transmits the signal to the circuit board 30 of the electronic device 1 via the photosensitive circuit board 591 to form an image.

[0097] like Figure 16 As shown, when the camera module 50 is in the second state, the reflective surface 563 faces the second light-transmitting hole 514, the lens 57, and the photosensitive component 59, and is positioned opposite to the second light-transmitting hole 514 and the lens 57. The reflective surface 563 reflects the light incident from the second light-transmitting hole 514 to the lens 57 and the photosensitive component 59. Ambient light L can pass through the second light-transmitting area 101 and enter the mounting cavity 512 through the second light-transmitting hole 514. The reflective surface 563 reflects the light, and the light reflected by the reflective surface 563 passes through the lens 57 and the filter 594 to reach the photosensitive sensor 592. The photosensitive sensor 592 generates a signal based on the ambient light and transmits the signal to the circuit board 30 of the electronic device 1 via the photosensitive circuit board 591 to form an image.

[0098] In the camera module 50 shown in this embodiment, a reflector 56b is used to adjust the light path. The reflector 56b has a simple structure and a small size, which can not only save the material cost of electronic device 1, but also save the internal space of electronic device 1, and help to realize the miniaturization design of electronic device 1.

[0099] Please see Figures 17 to 19 , Figure 17 yes Figure 1 A schematic diagram of the structure of the first dimming element 56 in the fourth type of camera module 50 of the electronic device 1 shown. Figure 18 yes Figure 1 The diagram shows the structure of the fourth camera module 50 in the first state in the electronic device 1 shown. Figure 19 yes Figure 18 The diagram shows the structure of the camera module 50 in its second state. Figure 18 and Figure 19 The propagation path of ambient light L is illustrated using a dotted line with an arrow.

[0100] The camera module 50 shown in this embodiment differs from the first to third types of camera modules 50 described above in that the first dimming element 56 includes multiple reflective surfaces 563, with at least two reflective surfaces 563 used to reflect light incident from the light-incident surface 561 to the light-exit surface 562. In this embodiment, the first dimming element 56 includes a multi-fold prism 56c, which includes a first surface 564, a second surface 565, and multiple reflective surfaces 563. The multiple reflective surfaces 563 are connected sequentially and between the first surface 564 and the second surface 565. For example, the multi-fold prism 56c is a regular pentaprism with three reflective surfaces 563, namely a third reflective surface 563a, a fourth reflective surface 563b, and a fifth reflective surface 563c.

[0101] like Figure 18As shown, when the camera module 50 is in the first state, the first surface 564 of the multi-prism 56c serves as the light-inlet surface 561, facing the first light-transmitting hole 513 and positioned opposite to it. The second surface 565 serves as the light-outlet surface 562, facing the lens 57 and the photosensitive component 59, and positioned opposite to the lens 57. At least two reflecting surfaces 563 reflect the light incident on the light-inlet surface 561 to the light-outlet surface 562. For example, the ambient light L is perpendicular to the light-inlet surface 561. Ambient light L enters the first dimming element 56 from the first surface 564. The fourth reflective surface 563b reflects the light entering the first dimming element 56 from the first surface 564 to the fifth reflective surface 563c. The light is then reflected sequentially by the fifth reflective surface 563c, the second surface 565, and the third reflective surface 563a to the second surface 565. The light emitted from the second surface 565 passes through the lens 57 and the filter 594 to reach the photosensor 592. The photosensor 592 generates a signal based on the ambient light and transmits the signal to the circuit board 30 of the electronic device 1 via the photosensor circuit board 591 to form an image.

[0102] like Figure 19 As shown, when the camera module 50 is in the second state, the second surface 565 of the multi-prism 56c serves as the light-inlet surface 561, facing the second light-transmitting hole 514 and opposite to it. The first surface 564 serves as the light-outlet surface 562, facing the lens 57 and the photosensitive component 59, and opposite to it. At least two reflecting surfaces 563 reflect the light incident on the light-inlet surface 561 to the light-outlet surface 562. For example, the ambient light L is perpendicular to the light-inlet surface 561. Ambient light L enters the first dimming element 56 from the second surface 565. The fourth reflective surface 563b reflects the light entering the first dimming element 56 from the second surface 565 to the third reflective surface 563a. The light is then reflected sequentially through the third reflective surface 563a, the first surface 564, and the fifth reflective surface 563c back to the first surface 564. The light emitted from the first surface 564 passes through the lens 57 and the filter 594 to reach the photosensor 592. The photosensor 592 generates a signal based on the ambient light and transmits the signal through the photosensor circuit board 591 to the circuit board 30 of the electronic device 1 to form an image.

[0103] It should be noted that when the camera module 50 shown in this embodiment switches between the first state and the second state, the rotation angle of the first dimming element 56 is 108 degrees. In some other embodiments, the multi-fold prism 56c may not be a regular pentaprism. In this case, the rotation angle of the first dimming element 56 may also be other angles. This application does not impose specific restrictions on this.

[0104] In the camera module 50 shown in this embodiment, a multi-fold prism 56c is used as the first dimming element 56. The use of multiple reflective surfaces 563 to reflect light can increase the propagation path of ambient light L, enabling optical zoom with a longer focal length. This helps to improve the flexibility of the camera module 50 and enhance the user experience.

[0105] Please see Figures 20 to 22 , Figure 20 yes Figure 1 A schematic diagram of the structure of the first dimming element 56 of the fifth camera module 50 in the electronic device 1 shown. Figure 21 yes Figure 1 The diagram shows the structure of the fifth camera module 50 in the first state of the electronic device 1 shown. Figure 22 yes Figure 21 The diagram shows the structure of the camera module 50 in its second state. Figure 21 and Figure 22 The propagation path of ambient light L is illustrated using a dotted line with an arrow.

[0106] The camera module 50 shown in this embodiment differs from the first to fourth types of camera modules 50 described above in that the first dimming element 56 includes a first sub-dimming element 56d, a second sub-dimming element 56e, and a light-blocking element 56f. The first sub-dimming element 56d includes a first light-inlet surface 561d, a first light-outlet surface 562d, and a first reflective surface 563d. The first light-inlet surface 561d faces the first light-transmitting hole 513 and is disposed opposite to the first light-transmitting hole 513. The first light-outlet surface 562d faces the lens 57 and the photosensitive component 59 and is disposed opposite to the lens 57. The first reflective surface 563d connects the first light-inlet surface 561d and the first light-outlet surface 562d and is used to reflect light incident from the first light-inlet surface 561d to the first light-outlet surface 562d.

[0107] The second sub-dimming element 56e includes a second light-incoming surface 561e, a second light-outgoing surface 562e, and a second reflective surface 563e. The second light-incoming surface 561e faces the second light-transmitting aperture 514 and is disposed opposite to the second light-transmitting aperture 514. The second light-outgoing surface 562e faces the lens 57 and the photosensitive assembly 59 and is disposed opposite to the lens 57. The second reflective surface 563e connects the second light-incoming surface 561e and the second light-outgoing surface 562e and is used to reflect light incident from the second light-incoming surface 561e to the second light-outgoing surface 562e.

[0108] In this embodiment, both the first sub-dimming element 56d and the second sub-dimming element 56e include multi-fold prisms, and there are multiple first reflecting surfaces 563d and second reflecting surfaces 563e. At least two first reflecting surfaces 563d are used to reflect light incident from the first light-incoming surface 561d to the first light-outcoming surface 562d, and at least two second reflecting surfaces 563e are used to reflect light incident from the second light-incoming surface 561e to the second light-outcoming surface 562e. For example, both the first sub-dimming element 56d and the second sub-dimming element 56e include hexagonal prisms, and there are four first reflecting surfaces 563d and four second reflecting surfaces 563e.

[0109] The light-blocking component 56f is located between the first sub-dimming component 56d and the second sub-dimming component 56e to ensure that the light from the first sub-dimming component 56d and the second sub-dimming component 56e does not interfere with each other. Specifically, the light-blocking component 56f is located between a first reflective surface 563d and a second reflective surface 563e. For example, the light-blocking component 56f can be a light-blocking adhesive, which not only assembles the first sub-dimming component 56d and the second sub-dimming component 56e together but also serves a light-blocking function.

[0110] like Figure 21 As shown, when the camera module 50 is in the first state, ambient light L enters the first sub-dimming element 56d from the first light-inlet surface 561d. At least two first reflective surfaces 563d reflect the light entering the first sub-dimming element 56d from the first light-inlet surface 561d to the first light-outlet surface 562d. The light emitted from the first light-outlet surface 562d passes through the lens 57 and the filter 594 to reach the photosensitive sensor 592. The photosensitive sensor 592 generates a signal based on the ambient light and transmits the signal to the circuit board 30 of the electronic device 1 via the photosensitive circuit board 591 to form an image.

[0111] like Figure 22 As shown, when the camera module 50 is in the second state, ambient light L enters the second sub-dimming element 56e from the second light-inlet surface 561e. At least two second reflective surfaces 563e reflect the light entering the second sub-dimming element 56e from the second light-inlet surface 561e to the second light-outlet surface 562e. The light emitted from the second light-outlet surface 562e passes through the lens 57 and the filter 594 to reach the photosensitive sensor 592. The photosensitive sensor 592 generates a signal based on the ambient light and transmits the signal to the circuit board 30 of the electronic device 1 via the photosensitive circuit board 591 to form an image.

[0112] In the camera module 50 shown in this embodiment, the first dimming element 56 includes a first sub-dimming element 56d and a second sub-dimming element 56e. The first sub-dimming element 56d and the second sub-dimming element 56e are used to realize the front-facing and rear-facing camera functions, respectively. Since the first driving element 55 and the third conductive element 50c shown in the previous embodiment are not required, the first dimming element 56 can achieve real-time dual-camera functionality without rotation, simplifying the structure of the camera module 50 and improving its reliability. Furthermore, both the first sub-dimming element 56d and the second sub-dimming element 56e include multi-fold prisms. Using multiple first reflecting surfaces 563d and multiple second reflecting surfaces 563e to reflect light increases the propagation path of ambient light L, enabling longer focal length optical zoom. This helps improve the flexibility of the camera module 50 and enhances the user experience.

[0113] In some other embodiments, the camera module 50 may also include a first condenser lens and a second condenser lens. The first condenser lens is disposed on a first light-emitting surface 562d, and the second condenser lens is disposed on a second light-emitting surface 562e. The first and second condenser lenses can converge light, eliminating the need for a lens 57 and a lens bracket 58 in the camera module 50. This not only saves on the material cost of the camera module 50 but also reduces its size, contributing to the miniaturization of the electronic device 1. In this case, the first sub-dimming element 56d can be integrally formed with the first condenser lens, and / or the second sub-dimming element 56e can be integrally formed with the second condenser lens to simplify the material cost of the camera module 50.

[0114] Please see Figure 23 , Figure 23 yes Figure 1 A schematic diagram of the structure of the sixth camera module 50 in the first state in the electronic device 1 shown.

[0115] The difference between the camera module 50 shown in this embodiment and the first to fifth types of camera modules 50 described above is that the angle α between the photosensitive component 59 and the thickness direction (Z-axis direction in the figure) of the camera module 50 is greater than 0 degrees and less than 90 degrees. In other words, the photosensitive component 59 is tilted to reduce the space occupied by the photosensitive component 59 in the thickness direction of the camera module 50, which helps to reduce the thickness of the camera module 50 and achieve a thinner and lighter design for the electronic device 1.

[0116] Furthermore, the camera module 50 also includes a second dimming element 50h, which is located between the first dimming element 56 and the photosensitive element 59, and is used to adjust the light emitted from the first dimming element 56 to the photosensitive element 59. Specifically, the second dimming element 50h is located between the lens 57 and the photosensitive element 59. The second dimming element 50h may include a reflector, which is used to reflect the light emitted from the lens 57 to the photosensitive element 59, ensuring that the emitted light is perpendicularly incident on the photosensitive element 59, thus helping to improve the image quality of the camera module 50. In some other embodiments, the second dimming element 50h may also include a refractive prism or a multi-fold prism; this application does not impose specific limitations on this.

[0117] Please see Figure 24 , Figure 24 yes Figure 1 A schematic diagram of the structure of the seventh camera module 50 in the first state in the electronic device 1 shown.

[0118] The difference between the camera module 50 shown in this embodiment and the sixth type of camera module 50 described above is that the angle α between the photosensitive component 59 and the thickness direction (Z-axis direction in the figure) of the camera module 50 is equal to 90 degrees, so as to ensure that the photosensitive component 59 occupies the minimum space in the thickness direction of the camera module 50, which helps to reduce the thickness of the camera module 50 and realize the thin and light design of the electronic device 1.

[0119] Please see Figure 25 and Figure 26 , Figure 25 yes Figure 1 The diagram shows the structure of the eighth camera module 50 in the first state in the electronic device 1 shown. Figure 26 yes Figure 25 The diagram shows the structure of the camera module 50 in its second state.

[0120] The camera module 50 shown in this embodiment differs from the first to seventh types of camera modules 50 in that both the first light-shielding member 52 and the second light-shielding member 53 are made of electrochromic material. The first light-shielding member 52 covers the first light-transmitting hole 513, and the second light-shielding member 53 covers the second light-transmitting hole 514. The housing 51, the first light-shielding member 52, and the second light-shielding member 53 can be integrally formed. With this configuration, the housing 51 does not need to have the first light-transmitting hole 513 and the second light-transmitting hole 514; the first light-shielding member 52 and the second light-shielding member 53 can directly achieve light transmission and blocking, simplifying the structure of the camera module 50 and improving its structural stability.

[0121] In this embodiment, the light transmittance of the first light-shielding member 52 and the second light-shielding member 53 can change under the action of current to switch between a light-transmitting state and a light-shielding state. For example, the light transmittance can be adjusted by passing different amounts of current through the first light-shielding member 52 and the second light-shielding member 53, thereby achieving the switching between the light-transmitting state and the light-shielding state. When the first light-shielding member 52 and the second light-shielding member 53 are in the light-transmitting state, their light transmittance can be a first light transmittance. When the first light-shielding member 52 and the second light-shielding member 53 are in the light-shielding state, their light transmittance can be a second light transmittance, which is less than the first light transmittance. In some other embodiments, one of the first light-shielding member 52 and the second light-shielding member 53 is made of an electrochromic material and its transmittance can change under the action of current to achieve switching between light transmission state and light-shielding state. The other adopts other methods to achieve switching between opening and closing the light-transmitting hole. This application does not impose specific limitations on this.

[0122] like Figure 25 As shown, when the camera module 50 is in the first state, the first light-shielding member 52 is in a light-transmitting state and the first light-transmitting hole 513 is open, the second light-shielding member 53 is in a light-shielding state and the second light-transmitting hole 514 is closed, and the ambient light L can pass through the first light-transmitting area 201 and enter the mounting cavity 512 from the first light-shielding member 52 and the first light-transmitting hole 513.

[0123] like Figure 26 As shown, when the camera module 50 is in the second state, the first light-shielding member 52 is in a light-shielding state and closes the first light-transmitting hole 513, the second light-shielding member 53 is in a light-transmitting state and opens the second light-transmitting hole 514, and the ambient light L can pass through the second light-transmitting area 101 and enter the mounting cavity 512 from the second light-shielding member 53 and the second light-transmitting hole 514.

[0124] In the camera module 50 shown in this embodiment, the first light-shielding member 52 and the second light-shielding member 53 are made of electrochromic material. When light needs to pass through, the light transmittance can be increased by passing an electric current. When light needs to be blocked, the light transmittance can be reduced by passing an electric current. The structure of the first light-shielding member 52 and the second light-shielding member 53 does not need to be changed significantly, which helps to improve the structural stability of the camera module 50.

[0125] Please see Figures 27 to 28 , Figure 27 This is a schematic diagram of the structure of the second electronic device 1 provided in this application when it is in the unfolded state. Figure 28 yes Figure 27 The diagram shows the structure of electronic device 1 from another angle. Figure 29 yes Figure 27 The diagram shows the structure of the electronic device 1 in a folded state.

[0126] The electronic device 1 shown in this embodiment differs from the first type of electronic device 1 described above in that the electronic device 1 is a foldable phone, and the extension direction of the rotation axis of the electronic device 1 is the Y-axis direction. That is, the electronic device 1 can be relatively unfolded or relatively folded around the Y-axis direction. Figure 1 and Figure 2 The electronic device 1 shown is in an unfolded state. The electronic device 1 has a large dimension along the X-axis and a large display area. Figure 3 The electronic device 1 shown is in a folded state. Its dimensions along the X-axis are small, making it easy to carry. For example, Figure 1 and Figure 2 The unfolding angle of the electronic device 1 shown is 180 degrees. That is, Figure 1 and Figure 2 The electronic device 1 shown is in a flattened state.

[0127] It should be noted that slight deviations are allowed in the angles illustrated in the embodiments of this application. For example, Figure 1 and Figure 2 The statement that the unfolding angle of the electronic device 1 shown is 180 degrees means that the unfolding angle of the electronic device 1 can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. The angles illustrated in the following text can be understood in the same way.

[0128] It should be understood that the electronic device 1 shown in the embodiments of this application is a terminal capable of folding once. In some other embodiments, the electronic device 1 may also be a terminal capable of folding multiple times (more than twice). In this case, the electronic device 1 may include multiple parts, and two adjacent parts may be folded relatively close to each other to make the electronic device 1 folded, and two adjacent parts may also be unfolded relatively far apart to make the electronic device 1 unfolded.

[0129] The housing 10 includes a first housing 13, a second housing 14, and a rotating mechanism 15. The rotating mechanism 15 is connected between the first housing 13 and the second housing 14 to achieve a rotatable connection between them. The first housing 13 and the second housing 14 can rotate relative to each other via the rotating mechanism 15, allowing the electronic device 1 to switch between a folded state and an unfolded state. Specifically, the second housing 14 has a second light-transmitting area 101. The second housing 14 includes a frame 141 and a second display module 142. The second display module 142 is mounted on the frame 141 and has the second light-transmitting area 101. The second display module 142 is electrically connected to the processor 40. For example, the second display module 142 can be electrically connected to the processor 40 via a circuit board 30.

[0130] The first housing 13 and the second housing 14 can rotate relative to each other to be unfolded relative to each other, so that the electronic device 1 is in an unfolded state, such as Figure 1 and Figure 2 As shown. At this time, the rotating mechanism 15 is in the deployed state. For example, Figure 1 and Figure 2 The electronic device 1 shown is in a flattened state, with the angle between the first housing 13 and the second housing 14 being 180 degrees. At this time, the rotating mechanism 15 is also in a flattened state. The first housing 13 and the second housing 14 can also be rotated relative to each other to be positioned opposite each other, so that the electronic device 1 is in a folded state, such as... Figure 3 As shown. At this time, the rotating mechanism 15 is in the folded state.

[0131] The first display module 20 includes a first display portion 21, a second display portion 22, and a flexible display portion 23. The first display portion 21 is mounted on the first housing 13. The second display portion 22 is mounted on the second housing 14. The second display portion 22 is mounted on the side of the frame 141 opposite to the second display module 142. That is, the second display portion 22 and the second display module 142 are located on opposite sides of the frame 141. The flexible display portion 23 connects the first display portion 21 and the second display portion 22 and is disposed opposite to the rotation mechanism 15. The flexible display portion 23 is bendable about the Y-axis.

[0132] like Figure 1 and Figure 2 As shown, when the electronic device 1 is in the unfolded state, the first display portion 21 and the second display portion 22 unfold relative to each other, while the flexible display portion 23 remains flat without bending. The included angles between the first display portion 21, the second display portion 22, and the flexible display portion 23 are all 180 degrees. The first display module 20 has a large display area, enabling a large-screen display for the electronic device 1 and improving the user experience. When the user uses the electronic device 1, the first display module 20 faces the user, and the second display module 142 faces away from the user.

[0133] like Figure 3 As shown, when the electronic device 1 is in a folded state, the first display portion 21 and the second display portion 22 are positioned opposite each other, and the flexible display portion 23 is bent. At this time, the first display module 20 is in a folded state, and the exposed area of ​​the first display module 20 is relatively small, which can greatly reduce the probability of the first display module 20 being damaged, and achieve effective protection for the first display module 20. At this time, when the user uses the electronic device 1, the second display module 142 is placed facing the user.

[0134] It should be understood that the electronic device 1 shown in this embodiment is folded inwards, and the first display module 20 of the electronic device 1 in the folded state is located inside the housing 10. In some other embodiments, the electronic device 1 may also be folded outwards, in which case the first display module 20 of the electronic device 1 in the folded state is located outside the housing 10.

[0135] The circuit board 30, processor 40, and camera module 50 can all be mounted inside the second housing 14. For example... Figure 1 and Figure 2 As shown, when the electronic device 1 is in the unfolded state, the camera module 50 can be used as both a front-facing camera module and a rear-facing camera module for the electronic device 1. Figure 3 As shown, when the electronic device 1 is in a folded state, the camera module 50 can be used as a front-facing camera module of the electronic device 1.

[0136] In the electronic device 1 shown in this embodiment, the camera module 50 can perform the camera function in both the folded and unfolded states of the electronic device 1. This is equivalent to using one camera module 50 to achieve the function of three camera modules 50, which is equivalent to saving two camera modules 50.
