Description

Technical Field

[0001] The present application relates to the technical field of camera devices, and in particular to an optical path deflection component, a camera module and an electronic device. Background Art

[0002] With the development of mobile phone imaging, consumers have higher and higher requirements for the quality of photos and videos taken by mobile phones, especially for long-range shooting. The longer the focal length of the camera module required for long-range shooting, the larger the size of the camera module will be (especially the height dimension), which contradicts the thinness and lightness of the whole machine.

[0003] In the related art, a prism is usually used to reflect and deflect light to reduce the height size of the camera module.

[0004] However, although the height of the camera module can be reduced by using a prism to reflect light to change the direction of light propagation, as the number of times the prism reflects light increases, stray light is more likely to enter the image sensor, causing glare during imaging. Although stray light elimination structures can be set inside the prism or at the gluing position between prisms, this will face the problems of high manufacturing difficulty and high cost, making it difficult to meet mass production needs. Summary of the invention

[0038] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

[0040] (1) Connection via wired lines, such as Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, and direct cable connection;

[0041] (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.

[0042] 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:

[0043] (1) Satellite phone or cellular phone;

[0044] (2) Personal Communications System (PCS) terminals that can combine cellular radio telephones with data processing, fax, and data communications capabilities;

[0046] (4) conventional laptop and / or handheld receivers;

[0047] (5) Conventional laptop and / or palmtop radio telephone transceivers, etc.

[0048] 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.

[0049] 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 21 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 21 to meet the needs of the camera module 20 for imaging.

[0050] Combination Figure 2 As shown, the camera module 20 includes a lens 21, an image sensor 22 and an optical path deflection assembly 23. The image sensor 22 is spaced apart from the lens 21, and the optical axis of the image sensor 22 is parallel to the optical axis of the lens 21. In this embodiment, the lens 21 and the image sensor 22 are located on the same side of the optical path deflection assembly 23. The deflection effect of the optical path deflection assembly 23 on the light can change the propagation direction of the light, so that the arrangement of the lens 21 and the image sensor 22 in the overall optical path of the camera module 20 meets the imaging requirements. Specifically, the optical path deflection assembly 23 is used to deflect the light collected by the lens 21 to the image sensor 22.

[0051] For ease of understanding, the structure of the optical path deflection component 23 is described below.

[0052] Combination Figure 2 and Figure 3 As shown, the optical path deflection assembly 23 includes a plane reflector 231, a first prism 232, and a second prism 233. The plane reflector 231 is arranged in the outgoing light path of the first prism 232, and the plane reflector 231 is located in the incident light path of the second prism 233. Specifically, the plane reflector 231 uses its own reflection performance of light to reflect the outgoing light of the first prism 232 to the second prism 233. In this way, the optical path of the first prism 232 and the optical path of the second prism 233 form a whole, so that the optical path deflection assembly 23 can deflect the light to meet the light transmission needs between the lens 21 and the image sensor 22 when the camera module 20 is shooting.

[0053] For the convenience of description, the side of the plane reflector 231 for reflecting light is referred to as “reflection surface 2311 ”. That is, the plane reflector 231 has a reflection surface 2311 .

[0054] Continue to combine Figure 2 and Figure 3 As shown, the first prism 232 includes a first light-transmitting surface 2321 and a first inclined surface 2322. The first inclined surface 2322 is obliquely disposed between the first light-transmitting surface 2321 and the reflective surface 2311. The second prism 233 includes a second light-transmitting surface 2331 and a second inclined surface 2332. The second inclined surface 2332 is obliquely disposed between the second light-transmitting surface 2331 and the reflective surface 2311.

[0055] The first prism 232 and the second prism 233 have a deflection effect on the light incident therein. Specifically, the first prism 232 and the second prism 233 are optically dense media relative to the external environment. Considering that when light is emitted from an optically dense medium to an optically sparse medium, when the incident angle exceeds a certain angle (critical angle), the refracted light completely disappears, leaving only the reflected light, that is, total reflection occurs.

[0056] Taking the first prism 232 as an example, when the light in the first prism 232 propagates to the surface of the first prism 232, if the incident angle of the light exceeds the critical angle, the light is totally reflected and continues to propagate in the first prism 232; correspondingly, if the incident angle of the light is less than the critical angle, at least a portion of the light is refracted to be emitted from the first prism 232.

[0057] Therefore, for the first prism 232, the first light-transmitting surface 2321 can adapt to the external light entering the first prism 232. If the light exceeds the critical angle when it enters the first light-transmitting surface 2321 from the first prism 232, the light will be totally reflected at the first light-transmitting surface 2321 to continue to propagate in the first prism 232; correspondingly, if the light is less than the critical angle when it enters the first light-transmitting surface 2321 from the first prism 232, the light will not be totally reflected at the first light-transmitting surface 2321, and then at least a part of the light will be emitted from the first prism 232 through the first light-transmitting surface 2321. It can be seen that for the first light-transmitting surface 2321, on the one hand, it can meet the need for external light to enter the first prism 232, and on the other hand, when the light enters the first light-transmitting surface 2321 from the first prism 232, it may be totally reflected or refracted.

[0058] In the optical path deflection assembly 23 of the present application, the plane reflector 231, the first prism 232 and the second prism 233 are all configured so that the optical path deflection assembly 23 can transmit the light from the lens 21 to the image sensor 22 to adapt the image sensor 22 to perform imaging.

[0059] Specifically, among the light rays transmitted from the first light-transmitting surface 2321 to the first prism 232, at least part of the light rays are deflected at least twice in the first prism 232 and are emitted from the first inclined surface 2322 to the reflecting surface 2311. Among the light rays emitted from the first inclined surface 2322 to the reflecting surface 2311, at least part of the light rays are reflected from the reflecting surface 2311 to the second inclined surface 2332, and among the light rays reflected from the reflecting surface 2311 to the second inclined surface 2332, at least part of the light rays are deflected at least twice in the second prism 233 and are emitted from the second light-transmitting surface 2331.

[0060] It is understandable that, since the lens 21 and the image sensor 22 are located on the same side of the optical path deflection assembly 23, the deflection effect of the optical path deflection assembly 23 on the light can change the propagation direction of the light, so that the arrangement of the lens 21 and the image sensor 22 in the overall optical path of the camera module 20 meets the imaging requirements. Based on this, the propagation path of the light in the camera module 20 can be: when the light passing through the lens 21 is transmitted from the first light-transmitting surface 2321 to the first prism 232, at least part of the light is deflected at least twice in the first prism 232 and reflected by the reflection surface 2311 to the second prism 233, and among the light reflected from the reflection surface 2311 to the second prism 233, at least part of the light is deflected at least twice in the second prism 233 and emitted from the second light-transmitting surface 2331 to the image sensor 22.

[0061] For ease of understanding, the light beam incident perpendicularly to the first light-transmitting surface 2321 is taken as an example to explain the propagation path of the light beam in the light path deflection assembly 23. However, this does not mean that the light path of the light path deflection assembly 23 is limited to the case where the light beam incident perpendicularly to the first light-transmitting surface 2321.

[0062] like Figure 2 As shown, in some embodiments, when light is incident vertically from the first light-transmitting surface 2321 to the first prism 232, the light is deflected at least twice by the first prism 232 and emitted from the first inclined surface 2322 to the reflective surface 2311, and the light reflected from the reflective surface 2311 to the second inclined surface 2332 can be deflected at least twice by the second prism 233 and emitted from the second light-transmitting surface 2331.

[0063] It should be noted here that Figure 2 Although the figure only shows that the light is deflected twice in the first prism 232, it is understandable that if the ratio of the size of the first prism 232 in the direction parallel to the reflecting surface 2311 (which may be referred to as the "length of the first prism 232") to the size in the direction perpendicular to the reflecting surface 2311 (which may be referred to as the "height of the first prism 232") increases, the light can be reflected more times in the first prism 232.

[0064] In the above embodiment, since the light undergoes at least two deflections in the first prism 232 and the second prism 233, and the reflective surface 2311 reflects the outgoing light of the first prism 232 to the second prism 233. Therefore, under the structural setting of the optical path deflection component 23, the light vertically incident from the first light-transmitting surface 2321 undergoes at least five deflections.

[0065] When the light is deflected by reflection, the incident angle and the reflection angle of the light are always equal and located on the same side of the corresponding reflection surface 2311. Therefore, in the embodiment of the present application, the light path deflection component 23 can be used to reduce the height of the camera module 20 and also lengthen the light propagation path, thereby maintaining the miniaturization of the module while meeting the telephoto shooting requirements.

[0066] Continue to combine Figure 2 and Figure 3 As shown, in this embodiment, the first inclined surface 2322 and the second inclined surface 2332 are arranged to be inclined relative to the reflective surface 2311. The first inclined surface 2322, the second inclined surface 2332 and the reflective surface 2311 together enclose a receiving space. The refractive index of the first prism 232 and the second prism 233 are both greater than the refractive index of the medium in the receiving space. It should be noted that the medium in the receiving space can be air in the use environment of the camera module 20.

[0067] Since the refractive index of the first prism 232 is greater than the refractive index of the medium in the receiving space, the condition for the light in the first prism 232 to pass through the first inclined surface 2322 needs to satisfy that the incident angle is less than the critical angle; for the light exceeding the critical angle, it will be totally reflected at the first inclined surface 2322 and cannot pass through the first inclined surface 2322, and then cannot be incident on the plane reflector 231.

[0068] Since in the camera module 20, stray light is usually a light beam that deviates from the optical axis of the lens 21 at a large angle and is prone to cause glare when entering the image sensor 22, the optical path deflection component 23 of the present application can utilize the first inclined surface 2322 of the first prism 232 to reflect the light that deviates from the optical axis of the lens 21 at a large angle out of the first prism 232 by total reflection, thereby reducing the stray light entering the image sensor 22 through the plane reflector 231 and the second prism 233, thereby reducing the probability of glare when the camera module 20 is shooting.

[0069] Since the optical path deflection assembly 23 of the present application uses the reflective performance of the plane reflector 231 to connect the optical paths of the first prism 232 and the second prism 233 into a whole, the module is miniaturized by deflecting the light. In addition, the first inclined surface 2322, the second inclined surface 2332 and the reflecting surface 2311 are used to enclose a receiving space, so that the refractive index of the first prism 232 and the second prism 233 is greater than the refractive index of the medium in the receiving space. Therefore, there is no need to set a stray light elimination structure inside the prism or at the gluing position between the prisms in the related art, and the probability of glare when the camera module 20 is photographed can be reduced. Due to this structural setting, the first prism 232 and the second prism 233 can be processed independently, and the structure is simple. Therefore, the optical path deflection assembly 23 of the present application can take into account the miniaturization of the module and reduce the glare phenomenon while reducing the manufacturing difficulty and cost.

[0070] It should be noted that, since the optical path deflection assembly 23 is used to deflect the light collected by the lens 21 to the image sensor 22, the arrangement positions of the lens 21 and the image sensor 22 relative to the optical path deflection assembly 23 only need to meet the shooting requirements of the camera module 20.

[0071] For example, in the camera module 20, the first light-transmitting surface 2321 is opposite to the lens 21 along the optical axis direction of the lens 21, so that the light collected by the lens 21 can be incident on the first prism 232 from the first light-transmitting surface 2321. The second light-transmitting surface 2331 is opposite to the image sensor 22 along the optical axis direction of the image sensor 22, so that the light emitted from the second light-transmitting surface 2331 by the second prism 233 can be incident on the image sensor 22.

[0072] The above-mentioned shooting module not only realizes that the light collected by the lens 21 enters the image sensor 22 after being deflected at least five times by the configuration of the optical path deflection component 23, thereby improving the telephoto shooting effect while reducing the module height, so as to facilitate the miniaturization of the module. In addition, since the first inclined surface 2322, the second inclined surface 2332 and the reflecting surface 2311 jointly enclose a receiving space, the refractive index of the first prism 232 and the second prism 233 are both greater than the refractive index of the medium in the receiving space, so that when the light in the first prism 232 enters the first inclined surface 2322, the stray light that deviates from the optical axis of the lens 21 at a large angle can be fully reflected, so as to reduce the probability of stray light entering the image sensor 22 through the plane reflector 231 and the second prism 233 and causing glare when the camera module 20 shoots. Therefore, the camera module 20 of the present application does not need to set a stray light elimination structure inside the prism or at the gluing position between prisms in the related art, so as to reduce the probability of glare when the camera module 20 is shooting.

[0073] Furthermore, the optical axis of the lens 21 is perpendicular to the first light-transmitting surface 2321, and the optical axis of the image sensor 22 is perpendicular to the second light-transmitting surface 2331. In this embodiment, based on the fact that the optical axis of the lens 21 is perpendicular to the first light-transmitting surface 2321, the light incident on the first light-transmitting surface 2321 along the optical axis of the lens 21 will be perpendicular to the first light-transmitting surface 2321, so as to improve the utilization rate of the light along the optical axis direction of the lens 21, which is conducive to ensuring the shooting effect of the camera module 20.

[0074] In addition, based on the fact that the optical axis of the lens 21 is perpendicular to the first light-transmitting surface 2321, and the optical axis of the image sensor 22 is perpendicular to the second light-transmitting surface 2331, the first prism 232 is stacked along the optical axis of the lens 21, and the second prism 233 is stacked along the optical axis of the image sensor 22, thereby avoiding the waste of space caused by the inclined stacking method. Therefore, under this structural setting, it is beneficial to maintain the shooting effect of the camera module 20 while making the stacking of the lens 21 and the image sensor 22 on the optical path deflection component 23 compact, so as to achieve the overall miniaturization of the shooting module.

[0075] It should be noted that, for the implementation mode of the present application, there are multiple implementation modes for the types of the first prism 232 and the second prism 233, as long as the first prism 232 and the second prism 233 satisfy the requirements of deflecting the light at least twice and adapting to the light collected by the lens 21 to be reflected to the image sensor 22 through the first prism 232, the plane reflector 231 and the second prism 233 in sequence.

[0076] For ease of understanding, the structure of the optical path deflection assembly 23 is further limited in combination with the structures of the first prism 232 and the second prism 233. However, this does not mean that the structure of the optical path deflection assembly 23 is limited thereto.

[0077] For example, combined with Figure 2 and Figure 3 As shown, the first prism 232 has a first connecting surface 2323, and the first connecting surface 2323 is opposite to the first light-transmitting surface 2321. The second prism 233 has a second connecting surface 2333, and the second connecting surface 2333 is opposite to the second light-transmitting surface 2331. The first connecting surface 2323 and the second connecting surface 2333 are both connected to the reflecting surface 2311. In this way, the first prism 232 and the second prism 233 can be stably installed on the reflecting surface 2311 of the plane reflecting mirror 231 by using the first connecting surface 2323 and the second connecting surface 2333 respectively. This structure is simple and easy to assemble.

[0078] The installation method of the first prism 232 and the second prism 233 includes but is not limited to gluing them to the reflective surface 2311 by glue.

[0079] In some embodiments, the surface of the plane reflector 231 on the side where the reflective surface 2311 is located includes a first bonding area and a second bonding area that are spaced apart. The side of the first prism 232 that faces away from the first light-transmitting surface 2321 is bonded to the first bonding area; correspondingly, the side of the second prism 233 that faces away from the second light-transmitting surface 2331 is bonded to the second bonding area. Then, the first prism 232 and the second prism 233 are stably connected to the plane reflector 231.

[0080] In some embodiments, the first prism 232 and the second prism 233 can also be connected to the plane reflector 231 through other structures such as a mounting base 24, so that the various components of the optical path deflection assembly 23 are stably connected as a whole, so that the optical path deflection assembly 23 can be assembled as a whole into the camera module 20 to improve assembly efficiency.

[0081] In some embodiments, the first prism 232 and the second prism 233 are both trapezoidal prisms. In this case, the first connecting surface 2323 and the second connecting surface 2333 can be understood as the smaller bottom surface between the upper bottom surface and the lower bottom surface of the trapezoidal prism.

[0082] It should be noted that the first prism 232 and the second prism 233 are not limited to being trapezoidal prisms. Figure 4 As shown, in some embodiments, one of the first prism 232 and the second prism 233 is a trapezoidal prism and the other is a triangular prism, as long as the first prism 232 and the second prism 233 meet the configuration requirements in the optical path deflection component 23. Figure 5 As shown, in some embodiments, the first prism 232 and the second prism 233 are both triangular prisms.

[0083] In the embodiments of the present application, a trapezoidal prism refers to a prism with a trapezoidal cross section, and a triangular prism refers to a prism with a triangular cross section.

[0084] In the embodiment of the present application, the first prism 232 and the second prism 233 can be trapezoidal prisms, triangular prisms, or other types of prisms, as long as the optical path deflection component 23 in the camera module 20 can transmit the light collected by the lens 21 to the image sensor 22 to meet the shooting needs.

[0085] In the camera module 20 provided with the optical path deflection component 23, the light collected by the lens 21 is deflected at least twice by the first prism 232, and is reflected to the second prism 233 through the reflection surface 2311, undergoes at least two deflections in the second prism 233, and finally is emitted from the second light-transmitting surface 2331 to the image sensor 22, thereby utilizing the deflection of the light to increase the focal length between the lens 21 and the image sensor 22, so as to adapt to the camera module 20 while taking into account miniaturization and maintaining a good telephoto shooting effect.

[0086] In some embodiments, the angle between the first inclined surface 2322 and the reflecting surface 2311 is equal to the angle between the second inclined surface 2332 and the reflecting surface 2311, so that the optical path of the light in the first prism 232 emitted from the first inclined surface 2322 to the reflecting surface 2311 has good symmetry with the optical path of the light reflected by the reflecting surface 2311 and entering the second prism 233 from the second inclined surface 2332, thereby facilitating the configuration of the lens 21 and the image sensor 22 in the incident optical path and the outgoing optical path of the optical path deflection assembly 23, thereby reducing the difficulty of assembling the components in the camera module 20.

[0087] In some embodiments, the first prism 232 and the second prism 233 have the same structure. Under this structural setting, since the first prism 232 and the second prism 233 have the same structure, when assembling the optical path deflection assembly 23, there is no problem that the first prism 232 and the second prism 233 of different models are easily misplaced. In short, under this structural setting, by unifying the structure of the first prism 232 and the second prism 233, the manufacture of the optical path deflection assembly 23 is simpler, the manufacturing cost is reduced, and it is conducive to achieving standardized operations.

[0088] The first prism 232 and the second prism 233 are mirror images of each other with a reference plane, and the reference plane is perpendicular to the reflection surface 2311. It can be understood that since the first prism 232 and the second prism 233 are mirror images on the reflection surface 2311, and the reflection surface 2311 itself can reflect the outgoing light of the first prism 232 to the second prism 233, therefore, under this structural setting, the propagation path of the light perpendicular to the first light-transmitting surface 2321 incident on the first prism 232 in the optical path deflection assembly 23 will also be mirror images with the reference plane, so that the optical path of this optical path deflection assembly 23 is simple. Thereby, it is convenient to configure the lens 21 and the image sensor 22 in the camera module 20 corresponding to the first prism 232 and the second prism 233 respectively.

[0089] In some embodiments, the first light-transmitting surface 2321 and the second light-transmitting surface 2331 are located in the same plane, and the first light-transmitting surface 2321 and the second light-transmitting surface 2331 are parallel to the reflective surface 2311. In this embodiment, since the first light-transmitting surface 2321 and the second light-transmitting surface 2331 are located in the same plane, the optical path deflection assembly 23 remains flush at the corresponding first light-transmitting surface 2321 and the second light-transmitting surface 2331, that is, there is no situation where some structures are abrupt and cause space waste, so as to facilitate the miniaturization of the camera module 20.

[0090] like Figure 4 and Figure 5 As shown, in some embodiments, the first prism 232 includes a first light reflecting surface 2324, and the first light reflecting surface 2324 and the first inclined surface 2322 are arranged to be inclined relative to the first light transmitting surface 2321. The first light transmitting surface 2321 includes a light input portion 23211 and a first reflective portion 23212 arranged at intervals. The second prism 233 includes a second light reflecting surface 2334, and the second light reflecting surface 2334 and the second inclined surface 2332 are arranged to be inclined relative to the second light transmitting surface 2331. The second light transmitting surface 2331 includes a second reflective portion 23311 and a light emitting portion 23312 arranged at intervals.

[0091] In the above embodiment, when light is incident from the first light-transmitting surface 2321 to the light-entering portion 23211 , at least part of the light is reflected by the first light-reflecting surface 2324 , the first light-reflecting portion 23212 , the light-reflecting surface 2311 , the second light-reflecting portion 23311 , and the second light-reflecting surface 2334 in sequence and is emitted from the light-emitting portion 23312 .

[0092] It can be understood that when the optical axis of the lens 21 is set perpendicular to the first light-transmitting surface 2321, the light emitted along the optical axis of the lens 21 will be incident on the light entrance portion 23211 in a direction perpendicular to the first light-transmitting surface 2321, and then the light will be reflected by the first reflecting surface 2324, the first reflecting portion 23212, the reflecting surface 2311, the second reflecting portion 23311, and the second reflecting surface 2334 in sequence and emitted from the light exit portion 23312.

[0093] When the optical axis of the image sensor 22 is perpendicular to the second light reflecting surface 2334, the light emitted from the light emitting portion 23312 will be incident on the image sensor 22 in parallel with the optical axis direction of the image sensor 22. Through reasonable settings, the center of the image sensor 22 can be adjusted to align with the light emitted from the light emitting portion 23312, so that the light collected by the lens 21 is accurately incident on the image sensor 22 for imaging after being deflected by the optical path deflection component 23.

[0094] Continue to combine Figure 4 and Figure 5 As shown, the angle between the first light reflecting surface 2324 and the first light transmitting surface 2321 is less than or equal to the angle between the first inclined surface 2322 and the first light transmitting surface 2321. With this structural arrangement, the area of ​​the first light reflecting surface 2324 corresponding to the lens 21 is increased while maintaining the first prism 232 relatively thin, so that the first light reflecting surface 2324 has a sufficient area to meet the need to receive the light emitted by the lens 21.

[0095] The angle between the second light reflecting surface 2334 and the second light transmitting surface 2331 is less than or equal to the angle between the second inclined surface 2332 and the second light transmitting surface 2331. With this structural arrangement, the area of ​​the second light reflecting surface 2334 corresponding to the image sensor 22 is increased while the second prism 233 is kept relatively thin, so that the second light reflecting surface 2334 has a sufficient area to satisfy the requirement of reflecting light toward the image sensor 22.

[0096] Based on the above implementation, the first prism 232 and the second prism 233 can be kept relatively thin to meet the light requirements of the camera module 20 during shooting, which is beneficial to the overall flat design of the optical path deflection assembly 23 and reduces the size of the camera module 20 in the thickness direction. It can be understood that the thickness direction of the camera module 20 can be understood as the size in the direction parallel to the optical axis of the lens 21.

[0097] Furthermore, the angle α between the first inclined surface 2322 and the first light-transmitting surface 2321 ranges from 40° to 50°, for example, the angle α is 40°, 43°, 45°, 47°, 48°, 49° or 50°.

[0098] The angle β between the second inclined surface 2332 and the second light-transmitting surface 2331 ranges from 40° to 50°, for example, the angle β is 40°, 43°, 45°, 47°, 48°, 49° or 50°.

[0099] Under this structural setting, the inclination angles of the first inclined surface 2322 and the second inclined surface 2332 are appropriate, which is conducive to taking into account the miniaturization of the first prism 232 and the second prism 233 while ensuring that normal light that deviates slightly from the optical axis direction of the lens 21 passes through the first inclined surface 2322 and is reflected by the mirror reflection surface 2311 to the second inclined surface 2332.

[0100] Combination Figure 6 and Figure 7 As shown, the camera module 20 also includes a mounting seat 24, and the plane reflector 231 is fixed to the mounting seat 24. The first prism 232 is movably connected to the mounting seat 24, and can approach or move away from the second prism 233 in a direction parallel to the reflection surface 2311. In this embodiment, on the one hand, the plane reflector 231 is fixed by the mounting seat 24 to ensure the installation stability of the plane reflector 231, and on the other hand, the first prism 232 is adjusted on the mounting seat 24 to achieve the first prism 232 approaching or moving away from the second prism 233 in a direction parallel to the reflection surface 2311, thereby adjusting the distance between the first prism 232 and the second prism 233, so that the light incident from the first prism 232 is finally at the position of the area where the second light-transmitting surface 2331 of the second prism 233 is emitted, so that the light collected by the lens 21 can be incident on the image sensor 22 after being reflected by the first prism 232, the plane reflector 231 and the second prism 233. That is to say, the arrangement of movably connecting the first prism 232 to the mounting base 24 makes it convenient to fine-tune the optical path when assembling the optical path deflection assembly 23 to the camera module 20, and facilitates the configuration of the camera module 20 such that the light collected by the lens 21 can be incident on the image sensor 22 for imaging after passing through the optical path deflection assembly 23.

[0101] It should be noted that the effect of the adjustable distance between the first prism 232 and the second prism 233 is not limited to the above-mentioned convenient configuration of the positions of the components in the camera module 20. In some embodiments, this structural setting can also be used to adapt the camera module 20 for anti-shake. For example, the camera module 20 also includes an anti-shake drive component, which is connected to the first prism 232. The anti-shake drive component is used to drive the first prism 232 to approach or move away from the second prism 233 in a direction parallel to the reflecting surface 2311. In this way, by adjusting the relative distance between the first prism 232 and the second prism 233, the light collected by the lens 21 will be adjusted accordingly when passing through the optical path deflection assembly 23, so as to compensate for the jitter of the shooting field of view on the image sensor 22 caused by the jitter when the camera module 20 is shooting, thereby achieving an anti-shake effect.

[0102] The anti-shake driving component includes a driving motor, a piezoelectric motor and other structures. The type of the anti-shake driving component and the arrangement method in the optical path deflection assembly 23 are not limited here. As long as the anti-shake driving component can meet the requirements of adjusting the first prism 232 to be close to or away from the second prism 233 in a direction parallel to the reflection surface 2311 to meet the anti-shake requirements.

[0103] Combination Figure 8 As shown, in some embodiments, the optical path deflection assembly 23 further includes a first light barrier 25, and the first light barrier 25 is connected to the first inclined surface 2322. The first light barrier 25 can block stray light in the light incident on the first inclined surface 2322 to reduce the probability of stray light passing through the first inclined surface 2322 and being reflected to the second prism 233 by the reflecting surface 2311. This is because among the light collected by the lens 21, the light with a larger angle deviating from the optical axis of the lens 21 is closer to the edge of the first inclined surface 2322 when it is transmitted to the first inclined surface 2322 and is more likely to cause glare. Then, in the present application, the first light barrier 25 is set on the first inclined surface 2322 to block stray light incident on the edge of the first inclined surface 2322, thereby reducing the probability of glare in the camera module 20.

[0104] The optical path deflection assembly 23 further includes a second light barrier 26, which is connected to the second inclined surface 2332. The second light barrier 26 on the second inclined surface 2332 can block stray light that deviates from the optical axis of the lens 21 at a large angle, thereby reducing the stray light from entering the image sensor 22, so as to reduce the probability of glare in the camera module 20.

[0105] The image sensor 22 includes but is not limited to a charge coupled device (CCD) or a complementary metal oxide semiconductor device (CMOS Sensor).

[0106] Continue to combine Figure 8 As shown, in some embodiments, the camera module 20 further includes a filter element 27, which is disposed between the second light-transmitting surface 2331 and the image sensor 22. The filter element 27 is used to filter out interference light emitted from the second light-transmitting surface 2331 to prevent the interference light from reaching the image sensor 22 and affecting normal imaging. In one embodiment, the filter element 27 may be an infrared cutoff filter.

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.

Although in Fig. 9 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.

[0112] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors.

Fig. 9 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.

[0115] 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.
