[0036] As used herein, "electronic device" refers to a device that can receive and / or send communication signals, including but not limited to a device that is connected via any one or more of the following connection methods:

[0037] (1) Connection via wired lines, such as Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, and direct cable connection;

[0038] (2) Via wireless interfaces, such as cellular networks, wireless local area networks (WLAN), digital television networks such as DVB-H networks, satellite networks, and AM-FM broadcast transmitters.

[0039] An electronic device configured to communicate via a wireless interface may be referred to as a "mobile terminal". Examples of mobile terminals include, but are not limited to, the following electronic devices:

[0040] (1) Satellite phone or cellular phone;

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

[0044] (5) Conventional laptop and / or palmtop radio telephone transceivers, etc.

[0045] See also Figure 1 As shown, the electronic device 10 includes a housing 11, and the space enclosed by the housing 11 is used to set components of the electronic device 10 such as a camera module 20, a mainboard (not shown) and a battery (not shown). Among them, the mainboard can integrate the processor, power management module, storage unit and baseband chip of the electronic device 10. It can be understood that the electronic device 10 of the embodiment of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices 10.

[0046] In some embodiments, the housing 11 is provided with a light-transmitting portion 111, which may be a light inlet hole penetrating the housing 11, or a structural member such as glass or light-transmitting plastic. Taking the housing 11 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 the camera module 20 for imaging.

[0047] Combination Figure 2 and Figure 3 As shown, 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 is used as a carrier for mounting a 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 equipped with a motor 222 for moving the lens assembly 221 for zooming. Since the prism 24 is in the optical path between the lens 22 and the image acquisition module 23, it plays a role in reflection adjustment and extension of the optical path. Then, when the motor 222 in the lens 22 drives the lens assembly 221 to move for zooming, the camera module 20 can obtain a good telephoto imaging effect. The motor 222 includes but is not limited to a voice coil motor 222. Figure 4 As shown, the lens assembly 221 may include one or more lenses 221a with optical focal length. The lens 22 can collect incident light and adjust the light to improve the imaging quality of the camera module 20.

[0050] Continue to combine Figure 2 and Figure 3 As shown, the image acquisition module 23 is connected to the base 21. The image acquisition module 23 includes a mounting seat 23a, and the mounting seat 23a is fixed to the base 21. The mounting seat 23a and the base 21 can be connected by snap-fit ​​or glue, which is not limited here.

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

[0052] The prism 24 is connected to the base 21, and the prism 24 includes a first reflective surface 24a, a second reflective surface 24b and a translucent surface 24c. The first reflective surface 24a and the second reflective surface 24b are both inclined at an acute angle relative to the translucent surface 24c. The lens 22 and the image acquisition module 23 are both opposite to the translucent surface 24c, that is, the lens 22 and the image acquisition module 23 are located on the same side of the translucent surface 24c of the prism 24. In this way, the translucent surface 24c can meet the need for light to enter the prism 24 to be incident on the first reflective surface 24a. At the same time, after the first reflective surface 24a reflects the light to the second reflective surface 24b, the light will be emitted from the translucent surface 24c to the photosensitive surface of the image sensor 232 to meet the imaging needs. It can be understood that the prism 24 is configured as follows: the light is emitted along the optical axis through the lens assembly 221 to the first reflective surface 24a, the first reflective surface 24a reflects the light to the second reflective surface 24b, and the light is reflected from the light-transmitting surface 24c through the second reflective surface 24b to enter the image sensor 232. Specifically, the first reflective surface 24a is inclined to the optical axis of the lens assembly 221, and the second reflective surface 24b is inclined to the axis of the image sensor 232. Among them, the axis of the image sensor 232 can be understood as the perpendicular bisector of the photosensitive surface of the image sensor 232. Based on this structural setting, the light collected by the lens assembly 221 is deflected 180° through 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 accuracy requirements of the lens assembly 221 and the image acquisition module 23 can be reduced, making it easier to align and assemble the lens assembly 221, the prism 24 and the image acquisition module 23. 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 beneficial to reducing the space occupied by the camera module 20 in the thickness direction when it 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 translate on the side where the light-transmitting surface 24c is located, so as to adjust the projection area of ​​the photosensitive surface on the second reflective surface 24b along the axis direction of the image sensor 232. In this way, the shooting field of view caused by the shaking when the camera module 20 is shooting can be compensated, so as to achieve the optical anti-shake effect. It should be noted here that the translational movement of the image sensor 232 refers to the translational movement of the image sensor 232 in the plane where the photosensitive surface is located, that is, the moving direction of the image sensor 232 is parallel to the photosensitive surface. The image sensor 232 includes but is not limited to a charge coupled device (CCD) or a complementary metal oxide semiconductor device (CMOS Sensor).

[0054] In the camera module 20 provided in the embodiment of the present application, the prism 24 between the lens assembly 221 and the image sensor 232 has the effect of extending the light propagation path, thereby increasing the focal length during shooting, so that the camera module 20 obtains a good telephoto shooting effect. At the same time, the first anti-shake module OIS is used to drive the image sensor 232 to move in translation on the side where the light-transmitting surface 24c is located, so as to compensate for the image offset collected by the image sensor 232 caused by the shaking of the camera module 20 during the shooting process, so as to achieve an anti-shake effect. It should be noted here that the first anti-shake module OIS is arranged in the mounting seat 23a of the image acquisition module 23, and optical anti-shake is achieved by driving the image sensor 232 to move in translation. Then, 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 ghost image problem caused by the complexity of the optical path when the prism 24 is deflected for anti-shake in the related art. At the same time, due to this anti-shake design, the prism 24 only needs to be fixed to the base 21, and the prism 24 does not need to swing, thereby avoiding the crosstalk problem caused by the rotation of the prism 24 in the related art. The crosstalk problem here refers to the fact that when the image sensor 232 performs light sensing and imaging, the external light originally belonging to a pixel may pass through its adjacent pixels when it is incident at an oblique angle, thereby adversely affecting the imaging.

[0055] In some embodiments, the circuit board 231 is connected to the mounting base 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 base 23a, so that the image sensor 232 moves relative to the prism 24 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 and the circuit board 231 are fixed relative to the mounting base 23a to achieve stable imaging.

[0056] Combination Figure 3As shown, the first anti-shake module OIS 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, wherein the connecting portion 201a is fixed to the mounting seat 23a, and the side of the circuit board 231 facing 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 member 201c such as a spring or a spring, so that the floating portion 201b can float relative to the connecting portion 201a when an external force is applied. Of course, the flexible support sheet 201 itself is made of a material that can be elastically deformed. For example, the flexible support sheet 201 is a hollow steel sheet, and the elastic modulus of the corresponding hollow position of the steel sheet is less than the elastic modulus of the hollow position without setting the hollow position, so that the flexible support sheet 201 can be provided with a connecting portion 201a and a floating portion 201b that are elastically connected to each other by hollowing.

[0057] The first magnet 202 and the first coil 203 are arranged opposite to each other. When the first coil 203 is energized, the first coil 203 and the first magnet 202 generate a magnetic force to drive the image sensor 232 to translate relative to the mounting seat 23a in the plane where the photosensitive surface is located. When the image sensor 232 translates 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 resets relative to the connecting portion 201a so that the image sensor 232 returns to the initial position before the first anti-shake module OIS works. In this embodiment, the first anti-shake module OIS is used to drive the image sensor 232 to translate to adjust the position of the image sensor 232 relative to the mounting seat 23a, thereby compensating for the shake of the camera module 20 during shooting, achieving an anti-shake effect, and thus improving the shooting clarity.

[0058] The first magnet 202 and the first coil 203 can be arranged at positions that can achieve translational motion of the image sensor 232 relative to the mounting base 23a for optical image stabilization. For example, one of the first magnet 202 and the first coil 203 is arranged at the mounting base 23a or the connecting portion 201a, and the other is arranged at the floating portion 201b or the circuit board 231.

[0059] In the camera module 20, one or more groups 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 translate in any direction in the two-dimensional space of the plane where its photosensitive surface is located.

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

[0061] Combination Figure 2 and Figure 4 As shown, the camera module 20 includes a second anti-shake module 25, which is connected to the base 21 and is used to drive the movable seat 2221 to swing 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, so that the second anti-shake module 25 cooperates with the first anti-shake module OIS to jointly achieve anti-shake, so as to further improve the optical anti-shake performance of the camera module 20.

[0062] In order to facilitate understanding of the optical image stabilization principle of the camera module 20, the second image stabilization module 25 is used as an example to implement the image stabilization. Figures 4 to 6 The following is schematically explained by taking the case where the camera module 20 is shaking during shooting as an example.

[0063] like Figure 4 As shown, if the optical axis of the lens 22 is facing the photographed object W (regarded as a shooting point) during shooting, that is, the photographed object W is located on the optical axis of the lens 22. At this time, if there is no jitter, the light of the photographed object W will be incident on the center position of the image acquisition module 23 along the reflected light path of the lens 22, the first reflecting surface 24a and the second reflecting surface 24b of the prism 24. Figure 5 As shown, during the shooting process, the camera module 20 shakes in the direction of O→O'. For example, due to the shaking of the camera module 20, the photographed object W deviates from the optical axis distance d of the lens 22, and the light that should be incident on the center of the image acquisition module 23 will be offset, so that this offset will cause a jittery virtual image in the captured image. In this way, when the lens 22 optical path jitter compensation method is used to prevent shaking, the second anti-shake module 25 is required to drive the lens 22 to deflect relative to the prism 24. Specifically, in combination Figure 5 and Figure 6As shown, since the camera module 20 shakes in the direction of O→O' during shooting, in order to eliminate the adverse effects of the shaking on the imaging effect, 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, thereby offsetting the deviation of the lens 22 from the imaging angle corresponding to the photographed object W due to the shaking during shooting, thereby achieving anti-shake.

[0064] Continue 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 air-avoiding space B, and the movable seat 2221 can be movably arranged in the air-avoiding 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 relative to the fixed seat 25a in the air-avoiding space B around a direction perpendicular to the optical axis of the lens 22. Since the driving assembly 25b is arranged in the installation gap J between the fixed seat 25a and the movable seat 2221, the movable space of the movable seat 2221 is effectively utilized, the space utilization rate is improved, and it is conducive to the miniaturization of the camera module 20.

[0065] Furthermore, the driving assembly 25b includes a second magnet 251 and a second coil 252 that are arranged opposite to each other. When the second coil 252 is energized, it acts together with the second magnet 251 on the movable seat 2221 and the fixed seat 25a, so that the movable seat 2221 moves relative to the fixed seat 25a in a direction perpendicular to the optical axis of the lens 22. In this embodiment, the second coil 252 generates an interaction force with the second magnet 251 when it is energized, so as to realize the movement of the movable seat 2221 relative to the fixed seat 25a, so that the lens 22 moves relative to the prism 24, so as to change the propagation light 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, that is, the optical axis of the lens 22 is moved relative to the first reflective surface 24a, so that the light emitted along the optical axis of the lens 22 is incident from different positions of the first reflective surface 24a, thereby ensuring the telephoto shooting effect of the prism 24 in the camera module 20, and providing optical anti-shake that meets the imaging requirements of the image acquisition module 23 for the light passing through the prism 24, thereby improving the overall shooting effect of the camera module 20.

[0066] In some embodiments, in combination Figure 7 As shown, the prism 24 includes a refractive portion 24d, which is located on the optical path of the light collected by the lens assembly 221 and incident on the image acquisition module 23, and is used to refract the light passing through the refractive portion 24d. Figure 8 and Fig. 9As shown, the prism 24 can not only utilize the reflection effect of the first reflecting surface 24a and the second reflecting surface 24b on the light to lengthen the optical path length of the light collected by the lens assembly 221 and incident on the image acquisition module 23 to obtain a good telephoto effect, but also utilize the refractive portion 24d to refract the light to coordinate the focusing effect produced by the driving portion 2222 moving the lens assembly 221 to reduce the load burden of the driving portion 2222 on the lens assembly 221, and then a smaller driving portion 2222 can be configured to meet the zooming needs, so as to reduce the volume of the lens 22, thereby facilitating the overall miniaturization of the camera module 20.

[0067] like Figure 8 and Fig. 9 As shown, the refractive portion 24d may be formed on the surface of the prism 24 facing the lens assembly 221. Specifically,

[0068] The refractive portion 24d is formed on the light-transmitting surface 24c, so that when the light passes through the position where the refractive portion 24d is formed on the light-transmitting surface 24c, it is refracted to meet the need of focal length adaptation.

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

[0070] For ease of understanding, the camera module 20 will be further described below by taking the first light reflecting surface 24a and the second light reflecting surface 24b as an example in which both the first light reflecting surface 24a and the second light reflecting surface 24b are provided with a light absorbing material layer. Figure 8 and Fig. 9 As shown, the light absorbing material layer disposed on the first light reflecting surface 24 a is referred to as a “first light absorbing member 243 ”, and the light absorbing material layer disposed on the second light reflecting surface 24 b is referred to as a “second light absorbing member 244 ”.

[0071] The first light absorbing member 243 is annular and encloses and defines a first light reflecting area on the first light reflecting surface 24a. The second light absorbing member 244 is annular and encloses and defines a second light reflecting area on the second light reflecting surface 24b. In this way, while the first light absorbing member 243 and the second light absorbing member 244 are used to absorb stray light, the first light reflecting area and the second light reflecting area can still meet the need for reflecting light.

[0072] In one embodiment, the first reflective surface 24a and the second reflective surface 24b may be coated with a reflective film layer to improve the reflection effect of the first reflective surface 24a and the second reflective surface 24b on light, thereby improving the light utilization rate of the camera module 20, which is beneficial to improving the imaging brightness and imaging quality of the camera module 20. The reflective film layer may be a reflection enhancement film, which is used to increase the reflectivity of the reflective surface of the prism 24.

[0073] Continue reading Fig.11 As shown, the first reflective surface 24a is provided with a first anti-reflection film 245, which covers the first reflective area, so that the first anti-reflection film 245 is used to improve the reflectivity of the light incident to the first reflective area, thereby increasing the amount of light entering the image sensor 232.

[0074] The second reflective surface 24 b is provided with a second anti-reflection film 246 , which covers the second reflective area. The second anti-reflection film 246 is used to increase the reflectivity of light incident on the second reflective area, thereby increasing the amount of light entering the image sensor 232 .

[0075] The first light absorbing member 243 and the second light absorbing member 244 may be formed on the prism 24 by means of silk-screen printing or spin-coating ink, or may be formed on the prism 24 by means of coating.

[0076] The refractive portion 24d can focus the light or diffuse the light. Fig.10 and Fig.11 As shown, the light-transmitting surface 24c has a convex spherical surface, and a refractive portion 24d is formed at the position of the convex spherical surface. In this way, the refractive portion 24d can have a focusing effect on the light passing through it.

[0077] Combination Fig.12 and Fig.13 As shown, the light-transmitting surface 24c has a concave spherical surface, and a refractive portion 24d is formed at the position of the concave spherical surface, so that the refractive portion 24d can have a dioptric effect on the light passing through it.

[0078] See again Fig.10 As shown, the fixing seat 25a has a light-transmitting hole 25c connected to the receiving space A, and the light-transmitting hole 25c can satisfy the light collected by the lens assembly 221 to enter the prism 24. Further, in the embodiment where the refractive portion 24d is formed on the surface of the prism 24 facing the lens 22, at least part of the structure of the refractive portion 24d is received in the light-transmitting hole 25c, and the light-transmitting hole 25c receives the refractive portion 24d, so that the assembly between the prism 24 and the lens 22 is more compact, thereby making the camera module 20 more compact and realizing a miniaturized design.

[0079] It should be noted that when the camera module 20 is in a normal state, that is, when the second anti-shake module 25 does not perform anti-shake work, the optical axis of the refractive portion 24d is coaxial with the optical axis of the lens 22. Based on this, when the second anti-shake module 25 needs to be enabled for anti-shake during the shooting process of the camera module 20, since the lens 22 will swing relative to the prism 24 under the drive of the second anti-shake module 25, the optical axis of the lens 22 will be at a certain deflection angle with the refractive portion 24d. The deflection angle is positively correlated with the jitter amplitude during shooting, that is, the greater the jitter amplitude, the greater the deflection angle required for the lens 22. In some embodiments, the maximum angle at which the second anti-shake module 25 drives the lens 22 to deflect relative to the prism 24 is 3°, that is, when the second anti-shake module 25 performs anti-shake work, 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. Fig.11 As shown, the optical axis of the refractive portion 24d is coaxial with the optical axis of the image acquisition module 23, so that the light passing through the refractive portion 24d enters 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 there are many possibilities for the number and location of the refractive parts 24d. Fig.14 As shown, the surface of the prism 24 facing the lens 22 and the surface of the prism 24 facing the image acquisition module 23 are both formed with a refractive portion 24d, one of which is coaxial with the optical axis of the lens 22, and the other is coaxial with the optical axis of the image acquisition module 23. For ease of understanding, the refractive portion 24d opposite to the lens 22 is referred to as the "first refractive portion", and the refractive portion 24d opposite to the image acquisition module 23 is referred to as the "second refractive portion". As long as the prism 24 is formed with at least one of the first refractive portion and the second refractive portion, the effect of reducing the number of lenses in the lens 22 can be achieved, thereby reducing the power required during zooming and anti-shake, so as to facilitate the miniaturization of the motor 222 and the second anti-shake module 25, and then realize the overall miniaturization of the camera module 20. It can be understood that the first refractive portion and the second refractive portion can both have a focusing effect, or both have an astigmatism effect. In other embodiments, one of the first refractive portions has a focusing effect, and the other has an astigmatism effect.

[0082] Combination Fig.15As shown, the first anti-shake module OIS includes multiple groups of first magnets 202 and first coils 203 arranged oppositely. The second anti-shake module 25 includes multiple groups of second magnets 251 and second coils 252 arranged oppositely. In some embodiments, the N pole of the first magnet 202 close to the fixing seat 25a and the N pole of the second magnet 251 close to the mounting seat 23a face 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 complementary magnetic field reinforcement, so as to improve the driving performance of the first anti-shake module OIS and the second anti-shake module 25 without increasing the cost of component setting, and improve the anti-shake effect.

[0083] Furthermore, the first magnet 202 near the fixing seat 25a and the second magnet 251 near the mounting seat 23a are integrally formed and penetrate the side wall of the mounting seat 23a and the side wall of the fixing seat 25a. This structural arrangement is compact, which improves the space utilization of the mounting seat 23a and the fixing seat 25a, so as to facilitate further miniaturization of the camera module 20.

[0084] See again Figure 2 and Figure 7 As shown, the prism 24 includes a first prism 241 and a second prism 242, and the first prism 241 and the second prism 242 are both configured to reflect light once. It should be noted that the first reflective surface 24a is located at the first prism 241, and the second reflective surface 24b is located at the second prism 242. The light-incoming side of the first prism 241 is arranged corresponding to the lens assembly 221, the light-outgoing side of the first prism 241 is arranged corresponding to the light-incoming side of the second prism 242, and the light-outgoing side of the second prism 242 is arranged corresponding to the image sensor 232. After the outgoing light of the lens assembly 221 is incident on the first prism 241, it is reflected by the first prism 241 and incident on the second prism 242, and then reflected by the second prism 242 and incident on the image sensor 232.

[0085] Further, in one embodiment, the first reflective surface 24a forms an angle of 45° with the optical axis of the lens assembly 221, the first reflective surface 24a and the second reflective surface 24b are perpendicular to each other, and the second reflective surface 24b forms an angle of 45° with the axis of the image sensor 232. Thus, the first reflective surface 24a and the second reflective surface 24b can deflect the light path by 90° respectively, so that the prism 24 can deflect the light path by 180°, so that the light incident on the prism 24 can be emitted from the prism 24 in a direction parallel to the incident direction and then be emitted to the image sensor 232.

[0086] Continue 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 notch that penetrates the mounting surface 21a, so that the prism 24 can be installed from the notch into the mounting groove 21b, and the mounting groove 21b is used to accommodate the prism 24. In some embodiments, after the prism 24 is installed in the mounting groove 21b, the surface of the prism 24 is flush with the mounting surface 21a or lower than the mounting surface 21a, so that the prism 24 does not protrude from the mounting surface 21a, so as to improve the sealing between the mounting seat 23a and the fixing seat 25a and the base 21.

[0087] The mounting groove 21 b has a first groove wall 21 b 1 and a second groove wall 21 b 2 that are relatively inclined, and the first prism 241 and the second prism 242 are respectively in contact with the first groove wall 21 b 1 and the second groove wall 21 b 2 .

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

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

[0090] Based on the fact that the lens 22 and the image acquisition module 23 are both 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, that is, 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 can be arranged side by side opposite to the prism 24.

[0091] Combination Figure 2As shown, in some embodiments, because 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 entire camera module 20 forms a step shape on the same side of the base 21, so as to facilitate the assembly of the camera module 20 to the electronic device 10, the lens assembly 221 protrudes from the back of the housing 11 of the electronic device 10, and the image acquisition module 23 is accommodated in the housing 11 of the electronic device 10. Compared with the stacking of the lens assembly 221 and the image acquisition module 23 in the thickness direction of the electronic device 10 in the prior art, the camera module 20 of the present application is conducive to reducing the thickness of the electronic device 10 corresponding to the position of the image acquisition module 23, so that the electronic device 10 is easier to achieve lightness and thinness as a whole, and the overall appearance and portability are improved. And under this structural setting, the lens assembly 221 will not be stacked with the image acquisition module 23 in the length direction or width direction of the electronic device 10, thereby reducing the occupation of the internal space of the electronic device 10, which is conducive to the miniaturization of the electronic device 10.

[0092] The mounting seat 23a and the fixing seat 25a are both sealed and connected to the base 21, and the adjacent side walls of the mounting seat 23a and the fixing seat 25a are sealed and connected to cover the notch of the mounting groove 21b together. In this way, the prism 24 disposed in the mounting groove 21b will be in a sealed environment, thereby avoiding 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 imaging quality.

[0093] The mounting surface 21a is a plane. When the fixing seat 25a is sealed and connected to the base 21, the mounting surface 21a can be used to improve the tightness of the fit between the base 21 and the fixing seat 25a. This 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, so as to facilitate the miniaturization of the camera module 20.

[0094] An adhesive connector 27 is provided around the notch of the mounting surface 21a, and the fixing seat 25a is sealed and connected to the base 21 through the adhesive connector 27. The adhesive connector 27 can be formed by curing the glue connecting the fixing seat 25a and the base 21, or it can be a double-sided tape. For example, when using glue 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 surfaces that need to be docked are matched, so that the glue is squeezed apart to prevent the formation of air holes. In this way, good structural 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 connector 27 formed by the curing of the glue can play a dustproof and waterproof effect, thereby extending 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 a sealant. In some embodiments, the mounting seat 23a and the fixing seat 25a can share a bonding member 27 and be sealed and connected to the base 21. In some embodiments, the mounting seat 23a and the fixing seat 25a can adopt different structures to be sealed and connected to the base 21. For example, in combination Fig.12 As shown, the fixing seat 25a is sealed and connected to the base 21 through a first seal 271, and the mounting seat 23a is sealed and connected to the base 21 through a second seal 272. If there is a gap between the mounting seat 23a and the fixing seat 25a, the gap between the two can be sealed with a 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 processing link between the mounting seat 23a and the fixing seat 25a is reduced to improve the processing efficiency.

[0096] Combination Figure 2 and Fig.16 As shown, the electronic device 10 can be provided with a decorative piece 12 at a position corresponding to the lens 22 to enhance the decorative effect of the position. Specifically, the decorative piece 12 is connected to the housing 11 and protrudes from the back of the housing 11, thereby meeting the need for the lens 22 to be provided and the need for thinness of other positions of the housing 11 to be met.

[0097] The base 21 of the camera module 20 is arranged in the space enclosed by the housing 11, and the image acquisition module 23 of the camera module 20 is located between the housing 11 and the base 21. The decorative member 12 has a groove 121 connected to the space enclosed by the housing 11, and a part of the structure of the lens 22 is accommodated in the groove 121. By accommodating a part of the structure of the lens 22 by the groove 121 of the decorative member 12, the stacking thickness of the electronic device 10 at the position of the decorative member 12 corresponding to the lens 22 can be reduced, so as to maintain the electronic device 10 thin and light, and reduce the protruding height of the decorative member 12 from the back of the housing 11, so as to enhance the overall aesthetics of the electronic device 10.

[0098] Combination Figure 2 and Figure 3 As shown, in some embodiments, the camera module 20 further includes a filter element 26, which is used to filter out interference light to prevent the interference light from reaching the image sensor 232 and affecting normal imaging. In one embodiment, the filter element 26 can be an infrared cutoff filter.

[0099] Furthermore, a support seat 23b is provided in the mounting seat 23a, and the support seat 23b is connected to 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 stacking of the filter element 26 in the thickness direction of the image sensor 232 is utilized to reduce the height difference between the fixing seat 25a and the mounting seat 23a, so that the height difference between the fixing seat 25a and the mounting seat 23a is not too large. Fig.16 As shown, based on the groove 121 being used to accommodate the lens 22, the depth of the groove 121 is adapted to the protruding height of the fixing seat 25a protruding from the mounting seat 23a. Reducing the height groove between the fixing seat 25a and the mounting seat 23a is thus conducive to thinning the thickness of the decorative member 12, and preventing the decorative member 12 from being too thick and too obtrusive. 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 lightweight design of the electronic device 10, and at the same time, it also avoids the decorative member 12 from being too obtrusive on the back of the housing 11, so as to maintain the overall aesthetic appearance of the electronic device 10.

[0100] refer to Fig.17 , Fig.17 The electronic device 10 is a schematic diagram of the structure of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509. Those skilled in the art will understand that Fig.17 The structure of the electronic device 10 shown in the figure does not constitute a limitation on the electronic device 10, and the electronic device 10 may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0102] The memory 502 can be used to store applications and data. The applications stored in the memory 502 contain executable codes. The applications can be composed of various functional modules. The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0103] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touch pad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable objects or accessories on or near the touch-sensitive surface), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

[0104] The display unit 504 can be used to display information input by the user or information provided to the user and various graphical user interfaces of the electronic device 10, which can be composed of graphics, text, icons, videos and any combination thereof. The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, the touch-sensitive surface may cover the display panel, and when the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Fig.17 In the embodiment, the touch sensitive surface and the display panel are used as two independent components to implement input and output functions, but in some embodiments, the touch sensitive surface and the display panel can be integrated to implement input and output functions. It can be understood that the display screen can include an input unit 503 and a display unit 504.

[0105] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel according to the brightness of the ambient light, and the proximity sensor may turn off the display panel and / or backlight when the electronic device 10 is moved to the ear. As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the electronic device 10 can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0106] The audio circuit 506 can provide an audio interface between the user and the electronic device 10 through a speaker and a microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit it to the speaker, and convert it into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, and then the audio data is output to the processor 508 for processing, and then sent to another electronic device 10 through the radio frequency circuit 501, or the audio data is output to the memory 502 for further processing. The audio circuit 506 may also include an earphone socket to provide communication between an external earphone and the electronic device 10.

[0107] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. The electronic device 10 can help users send and receive emails, browse web pages, and access streaming media through the wireless fidelity module 507, which provides users with wireless broadband Internet access. Fig.17 The wireless fidelity module 507 is shown, but it is understandable that it is not a necessary component of the electronic device 10 and can be omitted as needed without changing the essence of the invention.

[0108] The processor 508 is the control center of the electronic device 10. It uses various interfaces and lines to connect various parts of the entire electronic device 10. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it executes various functions of the electronic device 10 and processes data, thereby monitoring the electronic device 10 as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 508.

[0109] The electronic device 10 also includes a power supply 509 for supplying power to various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, so that the power management system can manage charging, discharging, and power consumption.

In specific implementation, the above modules can be implemented as independent entities, or can be arbitrarily combined and implemented as the same or several entities.

[0111] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
