Description

TECHNICAL FIELD

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

[0002] With the rapid development of electronic devices such as smart phones, tablet computers, and electronic readers, camera modules in electronic devices also tend to be diversified in design to meet different shooting needs. Some electronic devices are equipped with a long-focus camera module.

[0003] In related technologies, a long-focus camera module adopts a periscopic design to obtain a higher optical magnification for shooting. The periscopic camera module usually adopts a 45° prism reflection method to deflect the light collected by the lens by 90° to be incident on the image sensor.

[0004] However, in related technologies, it is difficult to balance the long-focus shooting effect and the anti-shake performance, and the long-focus camera module is prone to ghosting due to slight shaking. SUMMARY

[0005] Embodiments of the present application provide a camera module and an electronic device to solve the problem of how to balance the long-focus shooting effect while improving the anti-shake effect.

[0012] The camera module uses the reflection of the first reflecting surface and the second reflecting surface of the prism to lengthen the light path length of the light collected by the lens assembly and incident to the image collection module, so as to obtain a good telephoto effect, and uses the first anti-shake module to adjust the translational movement of the lower image sensor on the side where the light-transmitting surface is located, so as to change the position of the image sensor on the axis corresponding to the second reflecting surface, thereby achieving an optical anti-shake effect.

[0013] In another aspect, the application provides an electronic device including a housing, a decoration piece and the camera module as described above, the decoration piece is connected with the housing and protrudes from the back of the housing, the decoration piece has a groove in communication with a space enclosed by the housing, the base of the camera module is arranged in the space enclosed by the housing, the image collection module of the camera module is located between the housing and the base, and part of the structure of the lens is accommodated in the groove.

[0014] On the basis of improving the telephoto shooting effect and the anti-shake performance by using the camera module, the electronic device further accommodates the fixing seat of the camera module in the groove of the decoration piece, so as to reduce the stacking thickness at the position of the decoration piece, facilitate maintaining the thinness of the electronic device, reduce the protruding height of the decoration piece from the back of the housing, and improve the overall aesthetics of the electronic device.

[0037] (1) via a wired connection means, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection;

[0038] (2) via a wireless interface means, such as a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter.

[0039] Electronic devices configured to communicate over wireless interfaces can be referred to as "mobile terminals". Examples of mobile terminals include, but are not limited to, the following electronic devices:

[0040] (1) a satellite phone or a cellular phone;

[0041] (2) a Personal Communications System (PCS) terminal that can combine a cellular radiotelephone with data processing, facsimile, and data communications capabilities;

[0043] (4) a conventional laptop and / or palmtop receiver;

[0044] (5) a conventional laptop and / or palmtop radiotelephone transceiver, etc.

[0045] Referring to Figure 1 As shown in the figure, the electronic device 10 includes a housing 11, and elements such as a camera module 20, a mainboard (not shown in the figure), and a battery (not shown in the figure) are arranged in a space enclosed by the housing 11. The mainboard can integrate a processor, a power management module, a storage unit, and a baseband chip of the electronic device 10. It can be understood that the electronic device 10 of the embodiments of the present application includes, but is not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic device 10.

[0046] In some embodiments, the housing 11 is provided with a light-transmitting portion 111, which can be a light inlet hole penetrating through the housing 11, or a glass or light-transmitting plastic structure. Taking the case where the housing 11 is provided with a light inlet hole as an example, the camera module 20 is arranged in the space enclosed by the housing 11, and the lens 22 of the camera module 20 is arranged corresponding to the light inlet hole, so that light outside the electronic device 10 can enter the lens 22 to meet the needs of imaging by the camera module 20.

[0047] Referring to Figure 2 and Figure 3 As shown in the figure, the camera module 20 includes a base 21, a lens 22, an image acquisition module 23, a prism 24, and a first anti-shake module OIS.

[0048] The base 21 serves as a carrier for mounting the prism 24. The prism 24 mounted on the base 21 is used to reflect light, so that the light collected by the lens 22 can be transmitted to the image acquisition module 23.

[0049] The lens 22 is configured with a motor 222 for moving the lens assembly 221 to zoom. Since the prism 24 is in the light path between the lens 22 and the image capturing module 23, it has the effect of reflecting adjustment and lengthening the light path, and then when the motor 222 in the lens 22 drives the lens assembly 221 to move to zoom, the camera module 20 can obtain good long-focus imaging effect. The motor 222 includes but is not limited to a voice coil motor 222. In combination with Figure 4 As shown, the lens assembly 221 can include one or more lenses 221a with optical power, and the lens 22 can collect incident light and adjust the light, thereby improving the imaging quality of the camera module 20.

[0050] In combination with Figure 2 And Figure 3 As shown, the image capturing module 23 is connected to the base 21. The image capturing module 23 includes a mounting seat 23a fixed to the base 21. The mounting seat 23a and the base 21 can be connected by snap connection or glue connection, which is not limited here.

[0051] The image capturing module 23 includes a circuit board 231 and an image sensor 232. The image sensor 232 has a light receiving surface, and the side of the image sensor 232 away from the light receiving surface is attached to the circuit board 231 and electrically connected to the circuit board 231.

[0052] The prism 24 is connected with the base 21, and the prism 24 includes a first reflecting surface 24a, a second reflecting surface 24b and a light-transmitting surface 24c. The first reflecting surface 24a and the second reflecting surface 24b are both arranged at an acute angle with respect to the light-transmitting surface 24c. The lens 22 and the image acquisition module 23 are both opposite to the light-transmitting surface 24c, that is, the lens 22 and the image acquisition module 23 are located on the same side of the light-transmitting surface 24c of the prism 24. In this way, the light-transmitting surface 24c can meet the need of light entering the prism 24 to be incident on the first reflecting surface 24a, and meanwhile, after the light is reflected by the first reflecting surface 24a to the second reflecting surface 24b, the light will be emitted from the light-transmitting surface 24c to the light-sensitive surface of the image sensor 232 to adapt to the imaging need. It can be understood that the prism 24 is configured such that the light is emitted from the lens assembly 221 along the optical axis to the first reflecting surface 24a, the first reflecting surface 24a reflects the light to the second reflecting surface 24b, and the light is reflected by the second reflecting surface 24b out of the light-transmitting surface 24c to enter the image sensor 232. Specifically, the first reflecting surface 24a is inclined to the optical axis of the lens assembly 221, and the second reflecting surface 24b is inclined to the axis of the image sensor 232. The axis of the image sensor 232 can be understood as the median line of the light-sensitive surface of the image sensor 232. Based on this structural arrangement, the light collected by the lens assembly 221 is deflected by 180° by the prism 24 to be incident on the image sensor 232. Due to the structure that the image acquisition module 23 and the lens 22 are arranged on the same side of the prism 24, the optical alignment precision requirement of the lens assembly 221 and the image acquisition module 23 can be reduced, and the alignment assembly of the lens assembly 221, the prism 24 and the image acquisition module 23 is easier. At the same time, since the lens assembly 221 and the image acquisition module 23 are arranged side by side, the stacking thickness will not be increased, which is conducive to reducing the space occupied by the camera module 20 in the thickness direction when the camera module 20 is arranged in the electronic device 10, thereby facilitating the thinning of the electronic device 10.

[0053] The first anti-shake module OIS is arranged in the mounting seat 23a and is used to drive the image sensor 232 to perform translational motion on the side where the light-transmitting surface 24c is located, so as to adjust the projection area of the light-sensitive surface on the second reflecting surface 24b along the axis direction of the image sensor 232. In this way, the shooting field of view caused by shaking during shooting of the camera module 20 can be compensated, thereby achieving the optical anti-shake effect. It should be noted that the translational motion of the image sensor 232 refers to the translational motion of the image sensor 232 in the plane where the light-sensitive surface is located, that is, the movement direction of the image sensor 232 is parallel to the light-sensitive surface. The image sensor 232 includes but is not limited to a charge coupled device (CCD) or a complementary metal-oxide semiconductor sensor (CMOS sensor).

[0054] The embodiments of the present application provide that the prism 24 in the camera module 20 plays a role of extending the light propagation path between the lens assembly 221 and the image sensor 232, thereby increasing the focal length during shooting, so that the camera module 20 obtains good long-focus shooting effect. At the same time, the first anti-shake module OIS is used to drive the image sensor 232 to move translationally on the side where the light-transmitting surface 24c is located, so as to compensate for the image offset caused by the image sensor 232 during shooting due to shaking, so as to achieve the anti-shake effect. It should be noted that the first anti-shake module OIS is arranged in the mounting seat 23a of the image acquisition module 23, and the optical anti-shake is achieved by driving the image sensor 232 to move translationally, so that the first anti-shake module OIS performs optical anti-shake at the end of the optical path of the camera module 20. This anti-shake design does not increase the complexity of the optical path design, so as to avoid the flare ghosting problem caused by the complex optical path when the prism 24 is used for deflection in the related art. At the same time, due to this anti-shake design, the prism 24 is fixed to the base 21, and the prism 24 does not need to swing, so that the crosstalk problem caused by the rotation of the prism 24 in the related art can be avoided. The crosstalk problem refers to that when the image sensor 232 performs light sensing and imaging, the external light originally belonging to a certain pixel may pass through the adjacent pixel and adversely affect the imaging when the external light is incident at an oblique angle.

[0055] In some embodiments, the circuit board 231 is connected to the mounting seat 23a through the first anti-shake module OIS. The first anti-shake module OIS drives the circuit board 231 to move relative to the mounting seat 23a, so that the image sensor 232 moves translationally relative to the prism 24, so as to achieve anti-shake. It should be noted that when the first anti-shake module OIS does not drive the image sensor 232 to move, the image sensor 232 is fixed together with the circuit board 231 relative to the mounting seat 23a, so as to perform stable imaging.

[0056] In combination Figure 3As shown, the first OIS module includes a flexible support sheet 201, a first magnet 202 and a first coil 203. The flexible support sheet 201 includes a connecting portion 201a and a floating portion 201b, the connecting portion 201a is fixed to the mounting seat 23a, and the side of the circuit board 231 away from the image sensor 232 is fixed to the floating portion 201b. The floating portion 201b is elastically connected to the connecting portion 201a, and the two can be elastically connected by an elastic element 201c such as a spring or a spring, so that the floating portion 201b can float relative to the connecting portion 201a when subjected to external force. Of course, the flexible support sheet 201 itself adopts a material capable of elastic deformation, for example, the flexible support sheet 201 is a steel sheet with hollows, and the elastic modulus of the steel sheet at the hollow position is less than that at the position without hollow. Thus, the hollow can be used to make the flexible support sheet 201 have the connecting portion 201a and the floating portion 201b elastically connected to each other.

[0057] The first magnet 202 and the first coil 203 are oppositely arranged, and when the first coil 203 is energized, the first coil 203 and the first magnet 202 generate a magnetic force for driving the image sensor 232 to move in translation relative to the mounting seat 23a in the plane of the light-sensitive surface. When the image sensor 232 moves in translation relative to the mounting seat 23a, the floating portion 201b is displaced relative to the connecting portion 201a, and when the magnetic force is eliminated, the floating portion 201b moves in return relative to the connecting portion 201a to make the image sensor 232 return to the initial position before the first OIS module works. In this embodiment, the first OIS module is used to drive the image sensor 232 to move in translation to adjust the position of the image sensor 232 relative to the mounting seat 23a, thereby compensating for the shaking during the shooting of the camera module 20, achieving the effect of anti-shake, and improving the shooting clarity.

[0058] The positions of the first magnet 202 and the first coil 203 can be arranged as long as they can satisfy the requirement of moving the image sensor 232 in translation relative to the mounting seat 23a for optical anti-shake. For example, one of the first magnet 202 and the first coil 203 is arranged on the mounting seat 23a or the connecting portion 201a, and the other is arranged on the floating portion 201b or the circuit board 231.

[0059] In the camera module 20, one or more sets of first magnets 202 and first coils 203 are arranged corresponding to the four sides of the image sensor 232, so that the image sensor 232 can move in translation in any direction in the two-dimensional space of the plane of the light-sensitive surface.

[0060] In some embodiments, the motor 222 includes a movable base 2221 and a drive unit 2222. The drive unit 2222 is connected to the lens assembly 221 and is used to drive the lens assembly 221 to move relative to the movable base 2221 along the optical axis, thereby adjusting the moving distance of the lens assembly 221 along its optical axis and achieving zoom. In this embodiment, the movable base 2221 serves as a carrier for mounting the lens assembly 221 and the drive unit 2222 of the motor 222. The movable base 2221 encloses a receiving space A to accommodate the drive unit 2222 and the lens assembly 221, and provides space for the drive unit 2222 to drive the lens assembly 221 to move along the optical axis.

[0061] Combination Figure 2 and Figure 4 As shown, the camera module 20 includes a second image stabilization module 25, which is connected to the base 21 and is used to drive the movable seat 2221 to oscillate relative to the prism 24 in a direction perpendicular to the optical axis of the lens 22, so that the optical axis of the lens 22 moves relative to the first reflective surface 24a. Thus, the second image stabilization module 25 works in conjunction with the first image stabilization module OIS to stabilize the image, thereby further improving the optical image stabilization performance of the camera module 20.

[0062] To facilitate understanding of the optical image stabilization principle of camera module 20, the following example uses the second image stabilization module 25 to illustrate the process. Figure 4 to Figure 6 The illustration is based on the example of camera module 20 capturing images with shaking.

[0063] like Figure 4 As shown, if during shooting, the optical axis of lens 22 is directly facing the subject W (considered a shooting point), that is, the subject W is located on the optical axis of lens 22, then, if there is no shaking, the light from the subject W will be incident on the center position of image acquisition module 23 along the reflected light paths of the first reflective surface 24a and the second reflective surface 24b of lens 22 and prism 24. Figure 5 As shown, during the shooting process, the camera module 20 experiences shaking in the direction of O→O'. For example, due to the shaking of the camera module 20, the subject W deviates from the optical axis distance d of the lens 22, causing the light rays that should have been incident on the center position of the image acquisition module 23 to shift. This shift results in a blurry image in the captured image. Therefore, when using lens 22 optical path shake compensation for image stabilization, the second image stabilization module 25 is needed to drive the lens 22 to deflect relative to the prism 24. Specifically, in conjunction with... Figure 5 and Figure 6As shown, due to the shaking of the camera module 20 in the direction of O→O' during shooting, the second anti-shake module 25 drives the movable seat 2221 to swing in the direction of O'→O relative to the prism 24 around the direction perpendicular to the optical axis of the lens 22, so as to offset the deviation of the lens 22 from the imaging angle of view corresponding to the object W due to the shaking during shooting, thereby achieving anti-shaking.

[0064] Continuing to combine Figure 5 and Figure 6 As shown, the second anti-shake module 25 includes a fixed seat 25a and a driving assembly 25b. The fixed seat 25a has an empty space B, the movable seat 2221 is movably arranged in the empty space B, and an installation gap J is formed between the inner wall of the fixed seat 25a and the outer wall of the movable seat 2221. The driving assembly 25b is installed in the installation gap J and is used to drive the movable seat 2221 to swing in the direction perpendicular to the optical axis of the lens 22 relative to the fixed seat 25a in the empty space B. Since the driving assembly 25b is arranged in the installation gap J between the fixed seat 25a and the movable seat 2221, the activity space of the movable seat 2221 is effectively utilized, the space utilization is improved, and the miniaturization of the camera module 20 is facilitated.

[0065] Further, the driving assembly 25b includes a second magnet 251 and a second coil 252 arranged oppositely. When the second coil 252 is energized, it acts on the movable seat 2221 and the fixed seat 25a together with the second magnet 251, so that the movable seat 2221 swings relative to the fixed seat 25a in the direction perpendicular to the optical axis of the lens 22. In this embodiment, the interaction force generated by the energized second coil 252 and the second magnet 251 is used to realize the movement of the movable seat 2221 relative to the fixed seat 25a, so that the lens 22 swings relative to the prism 24 to change the propagation path in the prism 24. Due to this anti-shake design, the deflection angle of the lens 22 relative to the prism 24 is changed, i.e., the optical axis of the lens 22 moves relative to the first reflecting surface 24a, so that the light rays emitted along the optical axis of the lens 22 exit from different positions of the first reflecting surface 24a, thereby ensuring that the prism 24 plays a long-focus shooting effect in the camera module 20, and providing optical anti-shake that meets the imaging needs of the image acquisition module 23 for the light rays passing through the prism 24, so that the overall shooting effect of the camera module 20 is improved.

[0066] In some embodiments, in combination Figure 7 As shown, the prism 24 includes a dioptric part 24d located on the light path of the light rays collected by the lens assembly 221 to the image acquisition module 23 and used for refracting the light rays passing through the dioptric part 24d. In combination Figure 8 and Figure 9As shown, the prism 24 can not only use the first reflecting surface 24a and the second reflecting surface 24b to reflect the light rays to lengthen the light path length of the light rays collected by the lens assembly 221 to the image collection module 23 to obtain a good telephoto effect, but also use the refractive part 24d to refract the light rays to coordinate the focusing effect caused by the movement of the lens assembly 221 by the driving part 2222, thereby reducing the load burden of the driving part 2222 on the lens assembly 221, and then a smaller driving part 2222 can be configured to adapt to the zooming needs, thereby reducing the volume of the lens 22, and thus facilitating the overall miniaturization of the camera module 20.

[0067] As shown in Figure 8 and Figure 9 The refractive part 24d can be formed on the surface of the prism 24 opposite to the lens assembly 221, specifically,

[0068] The refractive part 24d is formed on the light-transmitting surface 24c, so that the light rays are refracted when passing through the position of the light-transmitting surface 24c where the refractive part 24d is formed, to adapt to the focal length adaptation needs.

[0069] At least one of the first reflecting surface 24a and the second reflecting surface 24b is attached with a light-absorbing material layer, which is used to absorb stray light in the light path between the lens assembly 221 and the image collection module 23.

[0070] For ease of understanding, the camera module 20 will be further described below with the first reflecting surface 24a and the second reflecting surface 24b both provided with a light-absorbing material layer as an example. Continue to combine Figure 8 and Figure 9 The light-absorbing material layer provided on the first reflecting surface 24a is referred to as a "first light-absorbing part 243", and the light-absorbing material layer provided on the second reflecting surface 24b is referred to as a "second light-absorbing part 244".

[0071] The first light-absorbing part 243 is annular and circumscribes a first reflecting area on the first reflecting surface 24a. The second light-absorbing part 244 is annular and circumscribes a second reflecting area on the second reflecting surface 24b. In this way, while the first light-absorbing part 243 and the second light-absorbing part 244 absorb stray light, the first reflecting area and the second reflecting area can still meet the reflection needs of the light rays.

[0072] In an embodiment, a reflective film layer can also be coated on the first reflecting surface 24a and the second reflecting surface 24b to improve the reflection effect of the light rays on the first reflecting surface 24a and the second reflecting surface 24b, thereby improving the light utilization rate of the camera module 20, and thus facilitating the improvement of the imaging brightness and the imaging quality of the camera module 20. The reflective film layer can be an anti-reflective film for increasing the reflectivity of the reflecting surface of the prism 24.

[0073] Continue to refer toFigure 11 As shown in

[0074] The second reflective surface 24b is provided with a second reflection-increasing film 246, which covers the second reflective region, so as to increase the reflectivity of the light rays incident to the second reflective region by means of the second reflection-increasing film 246, thereby increasing the number of light rays entering the image sensor 232.

[0075] The first and second light-absorbing members 243 and 244 can be formed on the prism 24 in the form of silk printing or spin-coated ink, or can be formed on the prism 24 in the form of plating.

[0076] The dioptric part 24d can have a light-converging effect or a light-diverging effect on the light rays. Exemplarily, as shown in Figure 10 and Figure 11 The light-transmitting surface 24c has a convex spherical surface, so that the dioptric part 24d is formed at the position of the convex spherical surface, and thus the dioptric part 24d can have a light-converging effect on the light rays passing therethrough.

[0077] As shown in Figure 12 and Figure 13 The light-transmitting surface 24c has a concave spherical surface, so that the dioptric part 24d is formed at the position of the concave spherical surface, and thus the dioptric part 24d can have a light-diverging effect on the light rays passing therethrough.

[0078] As shown in Figure 10 The fixing seat 25a has a light-transmitting hole 25c which is in communication with the accommodation space A, and the light-transmitting hole 25c can satisfy the requirement that the light rays collected by the lens assembly 221 enter the prism 24. Further, in the embodiment in which the dioptric part 24d is formed on the surface of the prism 24 which is opposite to the lens 22, at least part of the structure of the dioptric part 24d is accommodated in the light-transmitting hole 25c, and the accommodation of the dioptric part 24d by means of the light-transmitting hole 25c makes the assembly of the prism 24 and the lens 22 more compact, so that the camera module 20 is more compact and small in size, and the miniaturized design is achieved.

[0079] It should be noted that when the camera module 20 is in its normal state, i.e., when the second image stabilization module 25 is not performing image stabilization, the optical axis of the refractive index 24d is coaxial with the optical axis of the lens 22. Therefore, when the camera module 20 needs to activate the second image stabilization module 25 for image stabilization during shooting, the lens 22 will deflect relative to the prism 24 under the influence of the second image stabilization module 25, resulting in a certain deflection angle between the optical axis of the lens 22 and the refractive index 24d. This deflection angle is positively correlated with the amplitude of camera shake during shooting; that is, the greater the amplitude of shake, the greater the deflection angle required for the lens 22. In some embodiments, the maximum angle by which the second image stabilization module 25 causes the lens 22 to deflect relative to the prism 24 is 3°. In other words, when the second image stabilization module 25 is performing image stabilization, the deflection angle of the lens 22 is less than or equal to 3°.

[0080] In some embodiments, the refractive portion 24d may also be formed on the surface of the prism 24 facing the image acquisition module 23. Exemplarily, in conjunction with... Figure 11 As shown, the optical axis of the refractive section 24d is coaxial with the optical axis of the image acquisition module 23, so that the light rays passing through the refractive section 24d enter the image acquisition module 23 along the optical axis of the image acquisition module 23 to obtain a good imaging effect.

[0081] It should be noted that the number and location of the 24d refractive lenses can vary. For example, combining... Figure 14 As shown, both the surface of prism 24 facing lens 22 and the surface of prism 24 facing image acquisition module 23 have refractive portions 24d. One refractive portion 24d is coaxial with the optical axis of lens 22, and the other refractive portion 24d is coaxial with the optical axis of image acquisition module 23. For ease of understanding, the refractive portion 24d opposite to lens 22 is referred to as the "first refractive portion," and the refractive portion 24d opposite to image acquisition module 23 is referred to as the "second refractive portion." By forming at least one of the first and second refractive portions, prism 24 can reduce the number of lenses in lens 22, thereby reducing the power required for zooming and image stabilization, which facilitates the miniaturization of motor 222 and the second image stabilization module 25, and ultimately achieves overall miniaturization of camera module 20. Understandably, both the first and second refractive portions can have a focusing function or a diffusing function. In other embodiments, one of the first refractive portions functions as a focusing function, and the other as a diffusing function.

[0082] Combination Figure 15As shown, the first anti-shake module OIS includes a plurality of sets of oppositely arranged first magnets 202 and first coils 203. The second anti-shake module 25 includes a plurality of sets of oppositely arranged second magnets 251 and second coils 252. In some embodiments, the N-poles of the first magnets 202 close to the fixing seat 25a and the N-poles of the second magnets 251 close to the mounting seat 23a are oriented in the same direction, so that at least part of the magnets in the first anti-shake module OIS and the second anti-shake module 25 can achieve magnetic field complementary strengthening, thereby facilitating improvement of the driving performance of the first anti-shake module OIS and the second anti-shake module 25 without increasing the cost of setting components, and improving the anti-shake effect.

[0083] Further, the first magnets 202 close to the fixing seat 25a and the second magnets 251 close to the mounting seat 23a are integrally formed and arranged through the side walls of the mounting seat 23a and the fixing seat 25a. This compact structure improves the space utilization of the mounting seat 23a and the fixing seat 25a, thereby facilitating further miniaturization of the camera module 20.

[0084] Again referring to Figure 2 and Figure 7 As shown, the prism 24 includes a first prism 241 and a second prism 242, both of which are configured to be capable of reflecting light once. It should be noted that the first light-reflecting surface 24a is located at the first prism 241, and the second light-reflecting surface 24b is located at the second prism 242. The light-incoming side of the first prism 241 corresponds to the lens assembly 221, the light-outgoing side of the first prism 241 corresponds to the light-incoming side of the second prism 242, and the light-outgoing side of the second prism 242 corresponds to the image sensor 232. The outgoing light of the lens assembly 221 is reflected by the first prism 241 after being incident on the first prism 241, and then is reflected by the second prism 242 after being incident on the second prism 242, and then is reflected by the second prism 242 to the image sensor 232.

[0085] Further, in an embodiment, the first light-reflecting surface 24a forms a 45° angle with the optical axis of the lens assembly 221, the first light-reflecting surface 24a is perpendicular to the second light-reflecting surface 24b, and the second light-reflecting surface 24b forms a 45° angle with the axis of the image sensor 232. In this way, the first light-reflecting surface 24a and the second light-reflecting surface 24b can respectively deflect the light path by 90°, so that the prism 24 can deflect the light path by 180°, so that the light incident on the prism 24 can be reflected out of the prism 24 in a direction parallel to the incident direction and then to the image sensor 232.

[0086] Continuing to combine Figure 2 and Figure 7As shown, the base 21 has a mounting surface 21a and a mounting groove 21b. The mounting groove 21b has a slot through the mounting surface 21a, so that the prism 24 can be mounted into the mounting groove 21b from the slot, and the prism 24 is accommodated by the mounting groove 21b. In some embodiments, after the prism 24 is mounted in the mounting groove 21b, the surface of the prism 24 is flush with or lower than the mounting surface 21a, so that the prism 24 does not protrude from the mounting surface 21a, thereby facilitating the sealing between the mounting seat 23a and the fixing seat 25a and the base 21.

[0087] The mounting groove 21b has a first groove wall 21b1 and a second groove wall 21b2 arranged oppositely, and the first prism 241 and the second prism 242 are respectively fitted with the first groove wall 21b1 and the second groove wall 21b2.

[0088] In an embodiment, the first prism 241 and the second prism 242 are both right-angle prisms 24, and each of the first prism 241 and the second prism 242 includes two right-angle surfaces and one inclined surface. One of the right-angle surfaces of the first prism 241 faces the lens assembly 221, one of the right-angle surfaces of the second prism 242 faces the image sensor 232, and the other right-angle surface of the first prism 241 is arranged opposite to the other right-angle surface of the second prism 242. The inclined surface of the first prism 241 forms a first reflecting surface 24a, and the inclined surface of the second prism 242 forms a second reflecting surface 24b.

[0089] It should be noted that the first prism 241 and the second prism 242 are arranged side by side, thereby forming a light-transmitting surface 24c facing one side of the lens assembly 221 and the image acquisition module 23. Understandably, the first prism 241 and the second prism 242 can be an integral structure, i.e., the two are connected as one, and the prism 24 is an integral whole.

[0090] Based on the fact that both the lens 22 and the image acquisition module 23 are opposite to the light-transmitting surface 24c, in some embodiments, the image acquisition module 23 and the lens 22 are arranged side by side in the optical path. Specifically, the mounting seat 23a and the fixing seat 25a are both connected to the side where the mounting surface 21a is located, i.e., the side of the base 21 where the mounting groove 21b is opened, and the mounting seat 23a and the fixing seat 25a are arranged side by side. In this way, the image acquisition module 23 and the lens assembly 221 are arranged side by side opposite to the prism 24.

[0091] In combination Figure 2As shown, in some embodiments, due to the size of the lens assembly 221 along the optical axis direction is greater than the height of the image acquisition module 23, there is a height difference between the fixing seat 25a and the image acquisition module 23, so that the overall camera module 20 forms a step on the same side of the base 21, facilitating the assembly of the camera module 20 to the electronic device 10, the lens assembly 221 protrudes from the back of the shell 11 of the electronic device 10, and the image acquisition module 23 is accommodated in the shell 11 of the electronic device 10. With respect to the prior art, the stacking of the lens assembly 221 and the image acquisition module 23 in the thickness direction of the electronic device 10, the camera module 20 of the present application is beneficial to reduce the thickness of the electronic device 10 at the position corresponding to the image acquisition module 23, so that the electronic device 10 as a whole is easier to realize thin and light, and the overall appearance and portability are improved. And under this structure, the lens assembly 221 will not be stacked with the image acquisition module 23 in the length direction or the width direction of the electronic device 10, thereby reducing the occupation of the internal space of the electronic device 10, and then facilitating the miniaturization of the electronic device 10.

[0092] The mounting seat 23a and the fixing seat 25a are both sealingly connected with the base 21, and the mounting seat 23a and the fixing seat 25a are sealingly connected between the adjacent side walls, so as to jointly cover the slot of the mounting groove 21b. In this way, the prism 24 arranged in the mounting groove 21b will be in a sealed environment, thereby avoiding the phenomenon of light leakage, causing stray light to enter the image acquisition module 23 through the prism 24. Therefore, the camera module 20 of the present application can reduce the interference of stray light on imaging to improve the imaging quality.

[0093] The mounting surface 21a is a plane, and when the fixing seat 25a is sealingly connected with the base 21, the mounting surface 21a can be used to improve the close-fitting degree between the base 21 and the fixing seat 25a, which is not only beneficial to the sealing between the base 21 and the fixing seat 25a, but also can make the overall stacking of the camera module 20 compact, thereby facilitating the miniaturization of the camera module 20.

[0094] The slot of the mounting surface 21a is provided with an adhesive 27, and the fixing seat 25a is sealingly connected with the base 21 through the adhesive 27. The adhesive 27 can be formed by curing the glue connecting the fixing seat 25a and the base 21, or can be a double-sided tape. Exemplarily, when the glue is used to connect the fixing seat 25a and the base 21, the glue can be first applied to one of the fixing seat 25a and the base 21, and then the two surfaces to be connected are brought together, so that the glue is squeezed out to prevent air holes. In this way, the structure stability can be maintained, so that the lens 22 is not easy to fall off from the base 21; at the same time, the adhesive 27 formed by curing the glue can have the effect of dustproof and waterproof, thereby prolonging the service life of the camera module 20.

[0095] It should be noted that the mounting seat 23a and the fixing seat 25a can be sealed by sealant. In some embodiments, the mounting seat 23a can be sealed with the fixing seat 25a and the base 21 by the adhesive 27. In some embodiments, the mounting seat 23a and the fixing seat 25a can be sealed with the base 21 by different structures. For example, as shown in Figure 12 The fixing seat 25a and the base 21 are sealed by the first seal 271, and the mounting seat 23a and the base 21 are sealed by the second seal 272. If there is a gap between the mounting seat 23a and the fixing seat 25a, the gap can be sealed by sealant. In some embodiments, the mounting seat 23a can also be integrally formed with the fixing seat 25a by injection molding. In this way, the connection between the mounting seat 23a and the fixing seat 25a is stable, and the sealing process between the mounting seat 23a and the fixing seat 25a is reduced, thereby improving the processing efficiency.

[0096] As shown in Figure 2 and Figure 16 The electronic device 10 can be provided with a decorative piece 12 corresponding to the position of the lens 22 to improve the decoration effect of the position. Specifically, the decorative piece 12 is connected to the shell 11 and protrudes from the back of the shell 11, thereby adapting to the setting requirement of the lens 22 and meeting the thinning requirement of other positions of the shell 11.

[0097] The base 21 of the camera module 20 is arranged in the space enclosed by the shell 11, and the image acquisition module 23 of the camera module 20 is located between the shell 11 and the base 21. The decorative piece 12 has a recess 121 communicating with the space enclosed by the shell 11, and part of the structure of the lens 22 is accommodated in the recess 121. By accommodating part of the structure of the lens 22 in the recess 121 of the decorative piece 12, the stacking thickness of the electronic device 10 at the position of the lens 22 corresponding to the decorative piece 12 can be reduced, thereby facilitating the maintenance of the thinness of the electronic device 10 and reducing the protrusion height of the decorative piece 12 from the back of the shell 11, thereby improving the overall aesthetics of the electronic device 10.

[0098] As shown in Figure 2 and Figure 3 In some embodiments, the camera module 20 further includes a light filtering element 26 for filtering out interference light to prevent the interference light from affecting normal imaging by being incident on the image sensor 232. In an embodiment, the light filtering element 26 can be an infrared cut-off filter.

[0099] Further, the mounting seat 23a is provided with a support seat 23b, and the support seat 23b is connected with the circuit board 231. The filter element 26 is connected to the support seat 23b and is located between the image sensor 232 and the prism 24. In this way, the filter element 26 is stacked in the thickness direction of the image sensor 232, and the height difference between the fixing seat 25a and the mounting seat 23a is reduced, so that the height difference between the fixing seat 25a and the mounting seat 23a is not too large. In combination Figure 16 As shown, the groove 121 is used to accommodate the lens 22, and the depth of the groove 121 is adapted to the protruding height of the fixing seat 25a protruding from the mounting seat 23a. In this way, the height difference between the fixing seat 25a and the mounting seat 23a is reduced, which is conducive to reducing the thickness of the decorative piece 12 and avoiding the decorative piece 12 being too thick and too prominent. Therefore, in this embodiment, when the camera module 20 is assembled to the electronic device 10, on the one hand, it is conducive to realizing the thin design of the electronic device 10, and on the other hand, it also avoids the decorative piece 12 being too prominent on the back of the shell 11, so as to maintain the overall aesthetic appearance of the electronic device 10.

Specifically, in one embodiment, the input unit 503 can include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display or a touchpad, can collect touch operations (e.g., operations by a user using a finger, a stylus, or any suitable object or accessory on or near the touch-sensitive surface) on or near the touch-sensitive surface and drive corresponding connected devices according to a pre-set program. Optionally, the touch-sensitive surface can include two parts, a touch detection device and a touch controller.
