Description

Periscopic camera module and manufacturing method thereof Technical Field
The invention relates to the technical field of camera modules, in particular to a periscopic camera module and a manufacturing method thereof.
Background
In recent years, the demand for the camera function of portable electronic devices (such as tablet computers, smart phones, etc.) is still increasing rapidly, and the camera module configured for the electronic device gradually realizes a plurality of functions such as background blurring, night shooting, double-shot zooming, etc. In particular, due to the application of periscopic camera modules, the capability of the bi-zoom is gradually increasing, for example, the optical zoom capability thereof has been upgraded to 3 times zoom through 2 times zoom, even 5 times zoom. In other words, the periscopic camera module greatly changes the cognition of people on the shooting capability of the portable electronic equipment (such as a smart phone), and has a wide market prospect.
As is well known, the quality of the image captured by the camera module is closely related to the light input of the camera module, and the light input of the camera module is usually controlled by a diaphragm disposed on the camera module, and the larger the diaphragm (aperture diameter), the larger the light input of the camera module. For example, as shown in fig. 1, a conventional periscopic camera module 1P includes a photosensitive assembly 11P and a lens barrel unit 12P, wherein the lens barrel unit 12P includes a lens group 121P, a prism 122P and a liquid crystal dimming device 123P, wherein the lens group 121P and the prism 122P are sequentially disposed in a photosensitive path of the photosensitive assembly 11P, and the lens group 121P is located between the prism 122P and the photosensitive assembly 11P, wherein the liquid crystal dimming device 123P is mounted to an inclined surface of the prism 122P for changing an orientation of liquid crystal molecules under an applied voltage, thereby changing a light transmittance of the liquid crystal dimming device 123P. In other words, the light entering the prism 122P enters the liquid crystal dimming device 123P through the prism 122P, and then is reflected at the liquid crystal dimming device 123P, so that the reflected light passes through the prism 122P and the lens assembly 121P to be received and imaged by the photosensitive assembly 11P. At this time, the orientation of the liquid crystal molecules is adjusted by the driving of the liquid crystal layer voltage to change the amount of light reflected by the liquid crystal dimming device 123P, so that the amount of light passing through the prism 122P and the lens group 121P to be received by the photosensitive element 11P is changed, thereby changing the amount of light entering the periscopic camera module 1P.
However, in the process of adjusting the light entering amount by the conventional periscopic camera module 1P, the light is reflected and/or refracted for multiple times and enters and exits from multiple interfaces (such as the interface between the liquid crystal dimming device and the prism), which causes light energy loss, resulting in insufficient light amount during imaging. In addition, the liquid crystal dimming device 123P is difficult to be assembled on the inclined surface of the prism 122P, which results in high assembly cost of the conventional periscopic camera module 1P.

The periscopic camera module can realize long-focus shooting, has smaller module volume and particularly conforms to the trend of current more miniaturization development. The invention designs the light quantity adjusting component (such as an iris diaphragm) and the periscopic camera module in a matching way, thereby not only realizing the shooting mode of a large diaphragm with a long focus to achieve the effect of blurring the background when shooting the portrait and making the portrait more prominent; but also can realize the shooting mode that the small aperture lengthens the focus so as to realize the shooting of multiple times of long shot. Therefore, the periscopic camera module can combine the background blurring shooting function and the multiple long-distance scene shooting function into one camera module and can be switched to use.
Referring to fig. 2 to 6 of the drawings, a periscopic camera module according to a first embodiment of the present invention is illustrated. Specifically, as shown in fig. 2 and 3, the periscopic camera module 81 includes a module assembly 810, a light turning assembly 820, a light quantity adjusting assembly 830, and a circuit board assembly 840. The module assembly 810 has a photosensitive path 8100 for receiving light along the photosensitive path 8100 for imaging. The light turning element 820 is correspondingly disposed on the photosensitive path 8100 of the module 810, and the light turning element 820 has a light inlet 8201 and a light outlet 8202 facing the module 810, wherein the light turning element 820 is used for turning the light entering from the light inlet 8201 to exit from the light outlet 8202, so that the light exiting from the light outlet 8202 propagates along the photosensitive path 8100 to be received and imaged by the module 810. The light quantity adjusting assembly 830 is assembled at the light exit end 8202 of the light turning assembly 820 to be located between the light turning assembly 820 and the module assembly 810 for adjusting the quantity of light entering the module assembly 810. It is understood that the light amount adjusting member 830 is assembled between the light outlet end 8202 of the light turning member 820 and the module assembly 810 such that the light amount adjusting member 830 is positioned between the light turning member 820 and the module assembly 810 for adjusting the amount of light entering the module assembly 810 through the light turning member 820.
In other words, the light quantity adjusting assembly 830 and the light turning assembly 820 are sequentially located on the photosensitive path 8100 of the module assembly 810, and the light quantity adjusting assembly 830 is located between the module assembly 810 and the light outlet end 8202 of the light turning assembly 820, so that the light entering from the light inlet end 8201 of the light turning assembly 820 is firstly turned by the light turning assembly 820 to exit from the light outlet end 8202, and then is received by the module assembly 810 to form an image after the light quantity is adjusted by the light quantity adjusting assembly 830.
It should be noted that, since the light quantity adjusting assembly 830 is directly assembled to the light exit end 8202 of the light turning assembly 820, the periscopic camera module 81 of the present invention can fully utilize the internal space of the module, so that the internal structure of the module is more compact, which is helpful to reduce the overall size of the module. Meanwhile, the module assembly 810, the light turning assembly 820, and the light amount adjusting assembly 830 in the periscopic camera module 81 are independent of each other so that one component may be replaced independently when a problem occurs, without affecting other components, which contributes to reducing the maintenance cost of the periscopic camera module 81.
More specifically, as shown in fig. 4 and fig. 6, the light diverting assembly 820 of the periscopic camera module 81 may include a reflective element 821, a carrier 822 and a housing holder 823, wherein the housing holder 823 has a diverting passage 8230, wherein the reflective element 821 and the carrier 822 are both disposed in the diverting passage 8230 of the housing holder 823, and the reflective element 821 is carried on the carrier 822 to keep the reflective element 821 correspondingly located on the light sensing path 8100 of the module assembly 810, such that the light diverting assembly 820 is used for diverting the light entering from the light inlet end 8201 to exit from the light outlet end 8202 through reflection of the reflective element 821, and such that the light exiting from the light outlet end 8202 propagates along the light sensing path 8100 to be received by the module assembly 810 for imaging.
For example, in the first embodiment of the invention, as shown in fig. 4 and 6, the reflective element 821 of the light diverting assembly 820 can be implemented as a prism 8210, that is, the prism 8210 has a light incident surface 8211, a light emitting surface 8212 and a reflecting surface 8213, wherein the light incident surface 8211 of the prism 8210 is located at the light incident end 8201 of the light diverting assembly 820, and the reflecting surface 8213 of the prism 8210 is disposed on the carrier 822, wherein the light emitting surface 8212 of the prism 8210 is located at the light emitting end 8202 of the light diverting assembly 820, and the light emitting surface 8212 faces the module assembly 810, so that a light ray incident into the prism 8210 through the light incident surface 8211 is firstly deflected by the reflecting surface 8213 and then exits the prism 8210 through the light emitting surface 8212 to propagate along the photosensitive path 8100, and is received by the module assembly 810 for imaging. Of course, in other examples of the present invention, the reflective element 821 of the light turning component 820 may also be implemented as other optical elements such as a reflective plane mirror and a waveguide, or the reflective element 821 may also be replaced by a refractive element as long as the propagation direction of the light can be changed, which is not described in detail herein.
Preferably, the light incident surface 8211 of the prism 8210 is perpendicular to the light emitting surface 8212 of the prism 8210, so that the prism 8210 is implemented as a right-angle prism, and light rays perpendicularly incident into the prism 8210 through the light incident surface 8211 are firstly reflected by the reflecting surface 8213 to turn 890 degrees, then perpendicularly emergent from the prism 8210 through the light emitting surface 8212 to propagate along the photosensitive path 8100, and then received by the module assembly 810 to form an image. In other words, the light incident surface 8211 of the prism 8210 is parallel to the light sensing path 8100 of the module assembly 810, and the light emitting surface 8212 of the prism 8210 is perpendicular to the light sensing path 8100 of the module assembly 810, so that the light rays propagating perpendicular to the light sensing path 8100 can propagate along the light sensing path 8100 after being reflected by the prism 8210, so as to be received and imaged by the module assembly 810.
More preferably, as shown in fig. 6, the prism 8210 is completely accommodated in the housing bracket 823, that is, the light incident surface 8211 and the light emitting surface 8212 of the prism 8210 are both located in the turning channel 8230 of the housing bracket 823, so as to protect the prism 8210 and reduce wear.
It should be noted that, as shown in fig. 6, the light turning component 820 of the periscopic camera module 81 may further include an anti-shake driver 824, where the anti-shake driver 824 is disposed between the carrier 822 and the housing bracket 823, and is configured to drive the carrier 822 to drive the prism 8210 to rotate, so as to change a rotation angle of the prism 8210, so that the light turned by the prism 8210 can better propagate along the photosensitive path 8100, thereby achieving an anti-shake effect of the periscopic camera module 81, and facilitating improvement of image quality of the periscopic camera module 81.
Specifically, as shown in fig. 6, the carrier 822 of the light turning assembly 820 has a bearing surface 8221 and at least one non-bearing surface 8222, wherein the reflecting surface 8213 of the prism 8210 is disposed on the bearing surface 8221 of the carrier 822 in a face-to-face manner, and the anti-shake driver 824 is disposed between the non-bearing surface 8222 of the carrier 822 and an inner wall surface of the housing holder 823, and is configured to drive the carrier 822 to drive the prism 8210 to rotate, thereby achieving an anti-shake function of the periscopic camera module 81.
For example, as shown in fig. 6, the anti-shake driver 824 may include, but is not limited to, a magnet 8241 and a coil 8242, wherein the magnet 8241 is disposed on the non-bearing surface 8222 of the carrier 822, and the coil 8242 is correspondingly disposed on an inner wall surface of the housing bracket 823, such that the position of the magnet 8241 and the position of the coil 8242 correspond to each other, so as to form an electric motor for driving the carrier 822 to drive the prism 8210 to rotate under the action of electric power to achieve an anti-shake effect. Of course, in other examples of the present invention, the magnet 8241 may be disposed on an inner wall surface of the housing holder 823, and the coil 8242 may be correspondingly disposed on the non-bearing surface 8222 of the carrier 822 as long as an electric motor can be formed, and the positions of the magnet 8241 and the coil 8242 are not limited in the present invention.
In the first embodiment of the present invention, as shown in fig. 4 and 5, the circuit board assembly 840 of the periscopic camera module 81 includes a first circuit board 841, wherein the first circuit board 841 is disposed on the housing bracket 823 of the light turning assembly 820, and the first circuit board 841 is electrically connected to the anti-shake driver 824 for providing the electric energy required by the operation of the anti-shake driver 824, so that the prism 8210 rotates to achieve optical anti-shake.
Illustratively, as shown in fig. 3, the first circuit board 841 of the circuit board assembly 840 is attached to the outer side of the housing frame 823 of the light turning assembly 820 and located at the bottom side of the light turning assembly 820, wherein the first circuit board 841 is electrically connected to the anti-shake driver 824 directly through a lead (not shown) so as to realize the anti-shake function of the periscopic camera module 81. It is understood that the first circuit board 841 may also be electrically connected to the anti-shake driver 824 through conductive pins. In addition, the first circuit board 841 of the circuit board assembly 840 may be implemented as a hard board PCB, a soft board FPC or a hard-soft combined board, and the type of the first circuit board 841 is not limited in the present invention. It is understood that the bottom side mentioned in the present invention is defined as the side facing away from the light entrance end 8201 of the light turning assembly 820, and the front and rear sides mentioned in the present invention correspond to the light turning assembly 820 and the module assembly 810, respectively, that is, the light rays propagate from the front to the rear along the photosensitive path of the module assembly 810 to be received and imaged by the module assembly 810.
It is to be noted that the light quantity adjusting assembly 830 of the periscopic camera module 81 according to the above-described first embodiment of the present invention may be implemented as, but not limited to, various types of variable diaphragms such as voltage-type variable diaphragms, liquid crystal-type variable diaphragms, or blade-type variable diaphragms, so as to change the size of the diaphragm aperture of the variable diaphragm under the action of electric energy, thereby adjusting the quantity of light entering the module assembly 810. Therefore, the light quantity adjusting module 830 of the periscopic camera module 81 of the present invention is electrically connected to the circuit board assembly 840 to provide power to the light quantity adjusting module 830 through the circuit board assembly 840, so that the light quantity adjusting module 830 can adjust the amount of light entering the module assembly 810 under the action of the power.
More specifically, as shown in fig. 4 and 5, the circuit board assembly 840 may further include at least one electrical connection element 842, wherein the electrical connection element 842 electrically connects the light quantity adjusting assembly 830 and the first circuit board 841 together to transmit power to the light quantity adjusting assembly 830 through the first circuit board 841 and the electrical connection element 842.
In an example of the present invention, as shown in fig. 4 and 7A, the electrical connection element 842 may be implemented as a conductive pin 8421 electrically connected and disposed on the light quantity adjusting assembly 830, wherein the conductive pin 8421 extends from the bottom wall 8301 of the light quantity adjusting assembly 830 side by side and forwards to the first circuit board 841, so as to directly weld the conductive pin 8421 to the first circuit board 841, thereby achieving electrical connection between the light quantity adjusting assembly 830 and the first circuit board 841. It is understood that in other examples of the present invention, the conductive leads 8421 may also be electrically connected and adhered to the first circuit board 841 through a conductive adhesive, which is not described in detail herein.
It is noted that, since the conductive pins 8421 extend directly to the bottom of the light redirecting assembly 820 and the first circuit board 841 is assembled at the bottom of the light redirecting assembly 820, the conductive pins 8421 can directly contact the first circuit board 841 to electrically connect the first circuit board 841 by soldering, thereby achieving electrical connection between the first circuit board 841 and the light quantity adjusting assembly 830.
Of course, in the first modified example of the present invention, as shown in fig. 7B, the electrical connection element 842 may also be implemented as a lead wire 8422, wherein one end of the lead wire 8422 is electrically connected to the first circuit board 841, and the other end of the lead wire 8422 is electrically connected to the light quantity adjusting assembly 830, so that the light quantity adjusting assembly 830 at the light exit end 8202 of the light redirecting assembly 820 is electrically connected to the first circuit board 841 through the lead wire 8422.
As another example, in the second modified example of the present invention, as shown in fig. 7C, the electrical connection element 842 may include the conductive pin 8421 and the lead wire 8422, wherein the conductive pin 8421 is electrically connected to the light quantity adjustment assembly 830, wherein one end of the lead wire 8422 is electrically connected to the first circuit board 841, and the other end of the lead wire 8422 is electrically connected to the conductive pin 8421, so that the light quantity adjustment assembly 830 is electrically connected to the first circuit board 841 through the bonding between the conductive pin 8421 and the lead wire 8422, thereby facilitating the detachment of the light quantity adjustment assembly 830.
It should be noted that, according to the first embodiment of the present invention, as shown in fig. 2 and 5, the periscopic camera module 81 may further include an adhesive layer 850, wherein the adhesive layer 850 is located between the light quantity adjusting assembly 830 and the light exit end 8202 of the light turning assembly 820, so as to adhere the light quantity adjusting assembly 830 to the light exit end 8202 of the light turning assembly 820 through the adhesive layer 850, so that the light turned by the light turning assembly 820 firstly passes through the light quantity adjusting assembly 830 and then enters the module assembly 810 to be received and imaged after exiting from the light exit end 8202. Like this the periscopic camera module 81 can pass through the light quantity control subassembly 830 is adjusted more accurately and is got into the light quantity of module subassembly 810 for periscopic camera module 81 can also help improving self formation of image quality when satisfying the light input quantity demand of different shooting modes.
For example, as shown in fig. 8A and 8B, the light quantity adjusting assembly 830 of the periscopic camera module 81 may include, but is not limited to, a plurality of blades 831, a plurality of electric actuators 832 and a frame 833, wherein the blades 831 are partially overlapped and mounted on the frame 833 to form a diaphragm hole 8300 with an adjustable aperture through the blades 831, the electric actuators 832 are correspondingly disposed on the frame 833, and the electric actuators 832 are connected to the blades 831 in a one-to-one correspondence manner for actuating the corresponding blades 831 to adjust the aperture of the diaphragm hole 8300. It is to be appreciated that the electrical actuator 832 may include a magnet, a coil, and a lever, the coil, when energized, generating a magnetic field to drive the magnet in a particular direction to move the lever; the lever is connected to the blade 831, so that the blade 831 can change its position (e.g., rotate within a specific angle range) with the movement of the lever, thereby changing the aperture size of the diaphragm aperture 8300. In addition, the number and shape of the blades 831 in the light amount adjusting unit 830 may be any as long as the diaphragm holes 8300 having a variable aperture can be formed, and the present invention is not limited thereto.

Meanwhile, the adhesive layer 850 may be simultaneously located between the light amount adjustment unit 830 and the module unit 810, so that the light redirecting unit 820, the light amount adjustment unit 830, and the module unit 810 are sequentially adhered together by the adhesive layer 850 to be independently assembled into the periscopic camera module 81.
In particular, the adhesive layer 850 may be cured, but is not limited to, by an adhesive such as glue, so as to adjust the relative positions among the light turning member 820, the light quantity adjusting member 830 and the module assembly 810 before curing, to ensure that the center of the diaphragm hole 8300 of the light quantity adjusting member 830 is aligned or substantially aligned with the photosensitive path 8100 of the module assembly 810, so that the light turned by the light turning member 820 can pass through the diaphragm hole 8300 of the light quantity adjusting member 830 to enter the module assembly 810 to be subjected to image formation.
Illustratively, in the above example of the present invention, a circle of adhesive is applied on the frame 833 of the light quantity adjusting assembly 830, and then the light quantity adjusting assembly 830 is correspondingly placed at the light emitting end 8202 of the light turning assembly 820, and the adhesive is located between the housing bracket 823 of the light turning assembly 820 and the frame 833 of the light quantity adjusting assembly 830, so as to form the adhesive layer 850 after the adhesive is cured, so as to adhesively fix the light quantity adjusting assembly 830 to the light emitting end 8202 of the light turning assembly 820 through the adhesive layer 850; finally, an adhesive is applied between the light amount adjustment member 830 and the module assembly 810 to form the adhesive layer 850 that adhesively fixes the light amount adjustment member 830 and the module assembly 810 after the adhesive is cured.
Of course, in another example of the present invention, the light amount adjustment unit 830 and the module unit 810 are bonded together by the adhesive layer 850, and after the light amount adjustment unit 830 is debugged, the light exit end 8202 of the light redirecting unit 820 is correspondingly bonded to the light amount adjustment unit 830 by the adhesive layer 850, thereby completing the assembly of the periscopic camera module 81. Thus, before the light turning assembly 820 is assembled, the light quantity adjusting assembly 830 can be debugged by the photographing effect of the lens and the photosensitive chip to determine whether the center of the diaphragm hole 8300 of the light quantity adjusting assembly 830 is aligned with the optical center of the optical lens of the module assembly 810; alternatively, it is tested whether the effect of the opening and closing of the blades in the light quantity adjusting assembly 830 on the amount of incoming light can achieve the desired effect, and so on.

In addition, as shown in fig. 3 and 5, the second circuit board 844 of the circuit board assembly 840 of the present invention is usually located at the rear side of the module main body 810 of the periscopic camera module 81, so that the included angle between the second circuit board 844 and the first extension circuit board 845 is a right angle, and therefore, in order to electrically connect the second circuit board 844 and the first extension circuit board 845, the circuit board assembly 840 of the present invention may further include a first soft board 846, wherein the first soft board 846 is disposed between the first extension circuit board 845 and the second circuit board 844 in a bent manner, so as to electrically connect the first extension circuit board 845 and the second circuit board 844 through the first soft board 846. It is understood that the first soft board 846 may be implemented as a flexible board FPC capable of being bent, so that the first soft board 846 can reduce the size of the periscopic camera module 81 while stably and electrically connecting the first extension circuit board 845 and the second circuit board 844 together.
Further, as shown in fig. 3 and 10, the circuit board assembly 840 of the periscopic camera module 81 may further include a connector 847, wherein the connector 847 is electrically connected to the second circuit board 844 for electrically connecting to a motherboard of an electronic device, such as a mobile phone, so as to provide power and/or control signals for the circuit board assembly 840 through the motherboard of the electronic device. It is noted that the connector 847 is preferably electrically connected to the second circuit board 844 through a flexible connecting board 8470, so that the position of the connector 847 relative to the second circuit board 844 can be adjusted as needed to electrically connect to the main board of the electronic device.
It should be noted that, in an example of the present invention, the periscopic camera module 81 may further include a housing or an external bracket (not shown), wherein the module component 810, the light turning component 820, the light quantity adjusting component 830 and the circuit board component 840 are assembled in the housing or the external bracket, so that the module component 810, the light turning component 820, the light quantity adjusting component 830 and the circuit board component 840 are protected by the housing or the external bracket, and the module component 810, the light turning component 820, the light quantity adjusting component 830 and the circuit board component 840 are prevented from being contaminated.
It should be noted that fig. 11A shows a first variant of the periscopic camera module 81 according to the first embodiment of the present invention, wherein the light quantity adjusting assembly 830 is fastened to the light exit end 8202 of the light turning assembly 820, so as to omit the adhesive layer 850, and the light quantity adjusting assembly 830 is directly detachably assembled to the light turning assembly 820, so as to replace the light turning assembly 820 or the light quantity adjusting assembly 830.
Specifically, the light exit end 8202 of the light turning module 820 is provided with a first engaging structure 8231 located in the housing bracket 823, and the frame 833 of the light quantity adjusting module 830 is provided with a second engaging structure 8232 adapted to the first engaging structure, wherein when the first engaging structure 8231 and the second engaging structure 8232 are adapted to be engaged together, the frame 833 of the light quantity adjusting module 830 is mounted on the housing bracket 823 of the light turning module 820, so that the light quantity adjusting module 830 is assembled to the light exit end 8202 of the light turning module 820.
Preferably, as shown in fig. 11A, in the periscopic camera module 81 according to the first modified embodiment of the present invention, the first engaging structure 8231 is implemented as a groove provided in the housing holder 823, and the second engaging structure 8232 is implemented as a protrusion provided in the frame 833, so that the light quantity adjusting assembly 830 and the light steering assembly 820 are fixedly assembled by inserting the protrusion on the frame 833 into the groove on the housing holder 823, which not only reduces the size of the periscopic camera module 81, but also simplifies the assembly and disassembly of the periscopic camera module 81.
In particular, in order to further enhance the connection strength between the first fastening structure 8231 and the second fastening structure 8232, so that the light quantity adjusting assembly 830 is more firmly mounted to the housing bracket 823 of the light turning assembly 820, the adhesive layer 850 of the present invention may also be disposed between the first fastening structure 8231 and the second fastening structure 8232. For example, an adhesive is applied in the first fastening structure 8231 (i.e., the groove of the housing bracket 823), and then the first fastening structure 8231 and the second fastening structure 8232 are fastened to form the adhesive layer 850 between the first fastening structure 8231 and the second fastening structure 8232 after the adhesive is cured, so as to firmly fix the light quantity adjusting assembly 830 to the housing bracket 823 of the light turning assembly 820.
It should be noted that, although the first latching structure 8231 and the second latching structure 8232 of the periscopic camera module 81 are sequentially implemented as a groove and a protrusion to realize the latching connection between the light quantity adjusting assembly 830 and the light turning assembly 820 as shown in fig. 11A, the manner of latching is only an example, and the invention is not limited thereto. For example, as shown in fig. 11B, a second modified embodiment of the periscopic camera module 81 according to the above-described first embodiment of the present invention is illustrated, in which the first engagement structure 8231 of the periscopic camera module 81 is implemented as a protrusion provided to the housing holder 823, and the second engagement structure 8232 is implemented as a groove provided to the frame 833, so that the fixed assembly between the light quantity adjusting assembly 830 and the light turning assembly 820 is also achieved by inserting the protrusion on the housing holder 823 into the groove on the frame 833.
Specifically, referring to fig. 12 and 13 of the drawings, a periscopic camera module according to a second embodiment of the present invention is illustrated. Compared to the above-described first embodiment of the present invention, the periscopic imaging module 81 according to the second embodiment of the present invention differs in that: the light quantity adjusting member 830 is electrically connected directly to the first extension wiring board 845 of the wiring board assembly 840 without electrically connecting the light quantity adjusting member 830 indirectly to the first extension wiring board 845 through the first wiring board 841, so that the first wiring board 841 alone supplies power to the light redirecting member 820, contributing to simplification of the circuit design of the first wiring board 841.
Specifically, as shown in fig. 13, the electrical connection element 842 of the circuit board assembly 840 is implemented as the conductive pin 8421 electrically connected to the side wall 8302 of the light quantity adjusting assembly 830, wherein the conductive pin 8421 is soldered to the first extension circuit board 845, so as to electrically connect the light quantity adjusting assembly 830 to the first extension circuit board 845 through the conductive pin 8421.
Illustratively, as shown in fig. 12 and 13, the electrical connection component 842 includes two conductive pins 8421, wherein the conductive pins 8421 are disposed at intervals on an outer side wall of the frame 833 of the light quantity adjusting assembly 830, and the conductive pins 8421 are electrically connected to the electrical actuator 832 of the light quantity adjusting assembly 830, wherein the conductive pins 8421 can be electrically connected to the first extension circuit board 845 of the circuit board assembly 840 by means of solder balls, so as to provide electrical energy for the electrical actuator 832 of the light quantity adjusting assembly 830 through the first extension circuit board 845, thereby achieving the light intake quantity adjusting effect of the light quantity adjusting assembly 830. Of course, in other examples of the invention, the number of the conductive pins 8421 may exceed two, and the conductive pins 8421 may also be electrically and electrically bonded to the first extension circuit board 845 by means of a conductive adhesive.
Preferably, as shown in fig. 12, the first extension circuit board 845 of the circuit board assembly 840 is provided with two notches 8452, 8453, and the notches 8452, 8453 correspond to the conductive pins 8421 on the light quantity adjusting assembly 830, respectively, so that the conductive pins 8421 can be soldered to the first extension circuit board 845 at the notches 8452, 8453 of the first extension circuit board 845, respectively. It can be understood that, just because the first extension circuit board 845 is provided with the notches 8452 and 8453, the conductive pins 8421 can be electrically connected to the first extension circuit board 845 at the notches 8452 and 8453 of the first extension circuit board 845 by means of a solder ball, so that the size of the periscopic camera module 81 is prevented from being increased, and the soldering is also facilitated.
More preferably, as shown in fig. 12, one of the conductive pins 8421 is disposed on an upper portion of an outer sidewall of the frame 833 to form an upper pin; another conductive pin 8422 is disposed on a lower portion of the outer sidewall of the frame 833 to form a lower pin. The first extension circuit board 845 of the circuit board assembly 840 is provided with an upper notch 8452 and a lower notch 8453, and the upper notch 8452 and the lower notch 8453 of the first extension circuit board 845 correspond to the upper pin and the lower pin of the frame 833, respectively, so that the conductive pins 8421 are soldered to the first extension circuit board 845, respectively, thereby integrally and electrically connecting the light quantity adjusting assembly 830 to the first extension circuit board 845, for obtaining electric energy from the first extension circuit board 845 to adjust the quantity of light entering. It can be understood that the upper notch 8452 and the lower notch 8453 are arranged on the first extension circuit board 845, which is not only beneficial to welding the conductive pin 8421, but also beneficial to reducing the installation space of the periscopic camera module 81.
Fig. 14 and 15 show a modified embodiment of the periscopic camera module 81 according to the second embodiment of the present invention, in which the conductive pins 8421 extend from the side wall 8302 of the light quantity adjusting assembly 830 to the first extension circuit board 845 side by side and outward, so that the conductive pins 8421 are soldered to the first extension circuit board 845.
Illustratively, as shown in fig. 15, the conductive pins 8421 are electrically connected to the light quantity adjusting assembly 830, wherein the conductive pins 8421 extend side by side outward to protrude from the side wall 8302 of the light quantity adjusting assembly 830, so that the conductive pins 8421 are located on the bottom side of the first extended circuit board 845, that is, the conductive pins 8421 and the first extended circuit board 845 are located on the same side of the light quantity adjusting assembly 830, which facilitates soldering the conductive pins 8421 and the first extended circuit board 845 together.
It should be noted that, since the height of the second circuit board 844 of the circuit board assembly 840 of the periscopic camera module 81 of the present invention is substantially equal to the height of the periscopic camera module 81, and the connection flexible board 8470 for connecting the connector 847 and the second circuit board 844 does not protrude out of the side surface of the periscopic camera module 81, the bending angle of the connection flexible board 8470 for connecting the connector 847 and the second circuit board 844 is too large, and the circuit components of the connection flexible board 8470 are easily damaged.
Therefore, in order to solve the above problem, fig. 16 to 18 show a second modified embodiment of the periscopic camera module according to the above second embodiment of the present invention. The periscopic camera module 81 according to the second variant of the present invention differs from the above-described second embodiment of the present invention in that: the circuit board assembly 840 further includes a second extension circuit board 848 and a second flexible board 849, wherein the second flexible board 849 electrically connects the second extension circuit board 848 to the second circuit board 844 in a bendable manner, and the first flexible board 846 electrically connects the first extension circuit board 848 to the second extension circuit board 848 in a bendable manner. Specifically, the second extension wiring board 848 is stacked on the second wiring board 844, and the height of the second extension wiring board 848 is smaller than the height of the second wiring board 844, wherein the connector 847 is electrically connected to the second extension wiring board 848 in the height direction of the second extension wiring board 848 so as to electrically connect the wiring board assembly 840 to the main board of the electronic device through the connector 847.
It should be noted that, since the height of the second extension circuit board 848 is smaller than the height of the second circuit board 844 (as shown in fig. 18), so as to form a height difference between the second extension circuit board 848 and the second circuit board 844, the connecting soft board 8470 connected with the connector 847 still has enough space to bend without protruding out of the side surface of the periscopic camera module 81, so as to reduce the bending angle of the connecting soft board 8470, and further avoid the damage to the connecting soft board 8470 due to an excessively large bending angle.
Further, as shown in fig. 16 and 17, the periscopic camera module 81 further includes a gasket 860, wherein the gasket 860 is stacked between the second circuit board 844 and the second extension circuit board 848 to reduce the bending angle of the first soft board 846 and the second soft board 849, which helps to prevent the first soft board 846 and the second soft board 849 from being damaged due to too large bending.
Preferably, the gasket 860 is made of a metal material, so that the heat of the second circuit board 844 is transferred to the second extension circuit board 848 through the gasket 860, which helps to improve the heat dissipation performance of the periscopic camera module 81.
It should be noted that, in the second modified embodiment of the present invention, as shown in fig. 17, the first extension circuit board 845 and the drive circuit board 843 in the circuit board assembly 840 are integrally soldered and conducted by conductive pins, and the first extension circuit board 845 and the first circuit board 841 are integrally soldered and conducted by conductive pins, wherein the first extension circuit board 845 and the light quantity adjusting assembly 830 are integrally soldered and conducted by the conductive pins 8421, which is helpful for reducing the installation area of the periscopic camera module 81. It can be understood that the first circuit board 841, the driving circuit board 843, the light quantity adjusting assembly 830 and the first extension circuit board 846 of the circuit board assembly 840 are all connected into a whole by an electrical connection manner of conductive pin soldering, so that unstable performance caused by an overlarge integrated circuit board is avoided. Meanwhile, the first extension circuit board 846 can be electrically connected to the second extension circuit board 848 by the first soft board 847 in a bendable manner, and the second extension circuit board 848 can be electrically connected to the second circuit board 844 by the second soft board 849 in a bendable manner, so that the internal space of the periscopic camera module 81 is further utilized, the structure of the periscopic camera module 81 is more compact, and the volume of the periscopic camera module 81 is reduced.
Specifically, referring to fig. 19 of the drawings, a periscopic camera module according to a third embodiment of the present invention is illustrated. Compared to the second modified embodiment according to the second embodiment of the present invention, the periscopic imaging module 81 according to the third embodiment of the present invention is different in that: the electrical connection component 842 can be implemented as a conductive pin 8421 electrically connected to the light quantity adjusting assembly 830, wherein the conductive pin 8421 extends from the bottom wall 8301 of the light quantity adjusting assembly 830 to the driving circuit board 843 side by side and backwards, so as to directly solder the conductive pin 8421 to the driving circuit board 843, thereby achieving the electrical connection between the light quantity adjusting assembly 830 and the driving circuit board 843. It is understood that in other examples of the present invention, the conductive leads 8421 may also be electrically connected to the driving circuit board 843 by a conductive adhesive, which is not described in detail herein.
It is noted that, as shown in fig. 19, since the conductive pins 8421 directly extend to the bottom of the module assembly 810 and the driving circuit board 843 is just assembled to the bottom of the module assembly 810, the conductive pins 8421 can directly contact the driving circuit board 843 to electrically connect the driving circuit board 843 by soldering, so as to electrically connect the driving circuit board 843 and the light quantity adjusting assembly 830.
According to another aspect of the present invention, a method for manufacturing a periscopic camera module is further provided. Specifically, as shown in fig. 20A, the method for manufacturing the periscopic camera module includes the steps of:
s8100: assembling a light quantity adjusting assembly at a light outlet end of a light turning assembly, so that light rays incident from a light inlet end of the light turning assembly are firstly turned by the turning assembly and then emitted from the light outlet end, and then the light quantity passing through the light quantity adjusting assembly is changed by the adjustment of the light quantity adjusting assembly; and
s8200: arranging the light quantity adjusting assembly and the light turning assembly in a photosensitive path of a module assembly, wherein the light quantity adjusting assembly is positioned between the light turning assembly and the module assembly and is used for enabling the light rays passing through the light quantity adjusting assembly to be received by the module assembly for imaging; and
s8300: and electrically connecting a circuit board assembly to the light quantity adjusting assembly to provide electric energy required by the work for the light quantity adjusting assembly.
In an embodiment of the present invention, as shown in fig. 20B, the step S8300 of the method for manufacturing a periscopic camera module further includes the steps of:
s8310: electrically connecting a first circuit board to the light steering assembly to electrically connect the first circuit board to an anti-shake driver of the light steering assembly;
s8320: electrically connecting a second circuit board to the module assembly to electrically connect the second circuit board to a photosensitive chip of a photosensitive assembly of the module assembly;
s8330: a first extension circuit board is arranged on the module assembly and the light steering assembly in an extending mode, and the first extension circuit board is electrically connected to the first circuit board and the second circuit board respectively; and
s8340: the light quantity adjusting component is electrically connected to the first circuit board or the first extension circuit board through at least one electrical connection element.
In an example of the present invention, as shown in fig. 20B, the step S8300 of the method for manufacturing a periscopic imaging module further includes the steps of:
s8350: superposing a second extension circuit board on the second circuit board, and electrically connecting the second extension circuit board to the second circuit board through a second flexible board; and
s8360: the first extension circuit board is electrically connected to the second extension circuit board or the second circuit board through a first flexible board.
In an example of the present invention, as shown in fig. 20B, the step S8300 of the method for manufacturing a periscopic imaging module further includes the steps of:
s8370: a spacer is stacked between the second wiring board and the second extension wiring board.
According to the above embodiment of the present invention, as shown in fig. 20A, the method for manufacturing a periscopic imaging module further includes:
s8400: the light quantity adjusting assembly is adhered or buckled at the light outlet end of the light steering assembly; and
s8500: and correspondingly bonding the light quantity adjusting assembly to the module assembly.
It should be noted that, in an example of the present invention, as shown in fig. 20C, in order to accurately assemble the periscopic camera module 81, the method for manufacturing the periscopic camera module may further include the steps of:
s8610: pre-positioning the light amount adjustment member 830 and the module member 810 so that center lines of the light amount adjustment member 830 and the module member 810 are substantially aligned in an optical axis direction of the optical lens 811 of the module member 810;
s8620: adjusting the position of the light quantity adjusting assembly 830 according to the photographing effect of photographing a target through the photosensitive assembly 812 of the module assembly 810; and
s8630: the light quantity adjusting assembly 830 is adapted so that the size of the incident light quantity controlled by the light quantity adjusting assembly 830 meets a predetermined requirement.
As shown in fig. 20C, the method for manufacturing a periscopic camera module may further include:
s8640: pre-positioning the light redirecting assembly 820, the light amount adjusting assembly 830, and the module assembly 810 such that the centerlines of the light redirecting assembly 820, the light amount adjusting assembly 830, and the module assembly 810 are substantially aligned; and
s8650: the position of the light turning component 820 is adjusted according to the shooting effect of shooting the target through the light sensing component 812.
For example, when assembling the periscopic camera module 81, the light quantity adjusting assembly 830 and the module assembly 810 may be pre-positioned by a capturing tool such as a jig or a suction cup, so that the center lines of the light quantity adjusting assembly 830 and the module assembly 810 are substantially aligned (or approximately aligned) along the optical axis direction of the optical lens 811 of the module assembly 810, so that the photosensitive assembly 812 can capture an image of the target through the light quantity adjusting assembly 830; the position of the light quantity adjusting assembly 830 is adjusted according to the image quality (such as the SFR value of the image) so as to improve the degree of alignment between the light quantity adjusting assembly 830 and the optical axis of the optical lens 811; thereafter, the control effect of the light quantity adjusting assembly 830 is debugged to test whether the SFR value of the image reaches the expected SFR value during the adjustment of the light quantity adjusting assembly 830 within the light inlet quantity adjusting range, so as to facilitate the replacement of the light quantity adjusting assembly 830 which fails the test before the light turning assembly 820 is assembled.
Then, in the case where the light amount adjustment member 830 satisfies the requirement, the light redirecting member 820, the light amount adjustment member 830, and the module member 810 may be further pre-positioned such that the center lines of the light redirecting member 820, the light amount adjustment member 830, and the module member 810 are substantially aligned; and adjusts the position of the light turning component 820 according to the quality of the image (i.e. the shooting effect) shot by the light sensing component 812, so as to further improve the degree of alignment between the light turning component 820 and the optical axis of the optical lens 811; finally, after the adjustment and adjustment are completed, the light turning assembly 820, the light quantity adjusting assembly 830, and the module assembly 810 are positionally fixed to complete the manufacture of the periscopic camera module 81.
Of course, in other examples of the present invention, the relative position of the light steering assembly 820 may also be adjusted according to the SFR value of the captured image to test and adjust the anti-shake effect of the periscopic camera module 81; the relative position of the optical lens 811 of the module assembly 810 can be adjusted according to the SFR value of the captured image, so as to test and adjust the auto-focus effect or anti-shake effect of the periscopic camera module 81.
It should be noted that, although the steps of the method for manufacturing the periscopic camera module according to the present invention are sequentially depicted in the drawings, the order of the steps of the method for manufacturing the periscopic camera module according to the present invention is not limited thereto, and may be implemented in other orders. In addition, in other examples of the present invention, the method for manufacturing the periscopic camera module may include only a part of the steps shown in fig. 20A and 20B, or may include other steps besides the steps shown in fig. 20A and 20B, as long as one of the periscopic camera modules 81 can be manufactured, and the present invention is not described herein again.
Referring to fig. 21 to 23 of the drawings, a periscopic camera module according to a first embodiment of the present invention is illustrated. Specifically, as shown in fig. 21 and 22, the periscopic camera module 91 includes a module 910, a light turning module 920 and a light quantity adjusting module 930. The module assembly 910 includes a lens assembly 911 and a photosensitive assembly 912, wherein the photosensitive assembly 912 has a photosensitive path 9120 for receiving light along the photosensitive path 9120 for imaging, and the lens assembly 911 is correspondingly disposed on the photosensitive path 9120 of the photosensitive assembly 912 for converging light propagating along the photosensitive path 9120 for being received by the photosensitive assembly 912. The light turning component 920 is correspondingly disposed on the photosensitive path 9120 of the photosensitive component 912, and the lens component 911 of the module component 910 is disposed between the photosensitive component 912 and the light turning component 920, and is configured to bend the photosensitive path 9120 of the photosensitive component 912, so that light rays propagating along the photosensitive path 9120 are firstly turned by the light turning component 920 and then converged by the lens component 911 to be received and imaged by the photosensitive component 912.
The light quantity adjusting assembly 930 is assembled to the end portion 9200 of the light turning assembly 920, and the light quantity adjusting assembly 930 is located on the photosensitive path 9120 of the photosensitive assembly 912 for adjusting the quantity of light received by the photosensitive assembly 912. It can be understood that the end portion 9200 of the light turning component 920 includes a light inlet 9201 and a light outlet 9202 facing the module component 910, where the light turning component 920 is configured to extend the photosensitive path 9120 from the light inlet 9201 to the light outlet 9202 in a bending manner, so that light rays propagating along the photosensitive path 9120 are incident from the light inlet 9201, and are emitted from the light outlet 9202 after being turned, and then are received by the photosensitive component 912 for imaging.
It should be noted that, since the light quantity adjusting unit 930 is directly assembled to the end 9200 of the light turning unit 920, the module 910, the light turning unit 920 and the light quantity adjusting unit 930 in the periscopic camera module 91 are independent from each other, so that when one component goes wrong, the component can be replaced independently without affecting other components, which helps to reduce the maintenance cost of the periscopic camera module 91.
More specifically, in the above embodiment of the present invention, as shown in fig. 21 and 23, the light quantity adjusting component 930 is preferably assembled to the light outlet end 9201 of the light turning component 920, so that the light quantity adjusting component 930 is located between the light turning component 920 and the module component 910, which helps the periscopic camera module 91 of the present invention to fully utilize the internal space of the module, makes the internal structure of the module more compact, and helps to reduce the overall size of the module.
For example, as shown in fig. 23 and 24, the light diverting assembly 920 of the periscopic camera module 91 may include a reflecting element 921, a carrier 922 and a housing support 923, wherein the housing support 923 has a diverting channel 9230, wherein the reflecting element 921 and the carrier 922 are disposed in the diverting channel 9230 of the housing support 923, and the reflecting element 921 is carried on the carrier 922 to keep the reflecting element 921 correspondingly located on the photosensitive path 9120 of the module assembly 910. Meanwhile, the light quantity adjusting assembly 930 is mounted on the housing bracket 923 of the light turning assembly 920, and the light quantity adjusting assembly 930 is located at the light emitting end 9201 of the light turning assembly 920, so that light rays entering from the light entering end 9201 are first reflected by the reflecting element 921 to be turned, and then exit from the light emitting end 9202 after being turned, and then are adjusted by the light quantity adjusting assembly 930 to be received and imaged by the photosensitive assembly 912 of the module assembly 910.

It is understood that the electrical actuator 932 may include a magnet, a coil, and a toggle, wherein the coil, when energized, generates a magnetic field to move the magnet in a particular direction, thereby moving the toggle; the lever is connected to the blade 931 so that the blade 931 can change its position (e.g., rotate within a specific angular range, etc.) with the movement of the lever, thereby changing the aperture size of the diaphragm hole 9300. Further, the number and shape of the blades 931 in the light quantity adjusting unit 930 may be arbitrary as long as the diaphragm hole 9300 having a variable aperture can be formed, and the present invention is not limited thereto.

Meanwhile, the adhesive layer 950 may be simultaneously located between the light amount adjustment unit 930 and the lens assembly 911 of the module assembly 910, so that the light redirecting unit 920, the light amount adjustment unit 930, and the module assembly 910 are sequentially adhered together by the adhesive layer 950 to be independently assembled into the periscopic camera module 91.
In particular, the adhesive layer 950 may be cured by, but not limited to, an adhesive such as glue, so as to adjust the relative positions of the light turning member 920, the light quantity adjusting member 930 and the module assembly 910 before curing, and ensure that the center of the aperture hole 9300 of the light quantity adjusting member 930 is aligned or substantially aligned with the photosensitive path 9120 of the photosensitive assembly 912, so that the light turned by the light turning member 920 can pass through the aperture hole 9300 of the light quantity adjusting member 930 to enter the module assembly 910 to be received and imaged by the photosensitive assembly 912.

It should be noted that fig. 26 shows a first variant of the periscopic camera module 91 according to the above embodiment of the present invention, wherein the light quantity adjusting element 930 is directly fastened to the housing bracket 923 of the light turning element 920 and is located at the light exit end 9202 of the light turning element 920. In other words, the present invention directly and detachably assembles the light quantity adjusting component 930 to the light turning component 920, which facilitates easy replacement of the light turning component 920 or the light quantity adjusting component 930.
Specifically, as shown in fig. 26, the light emitting end 9202 of the light turning assembly 920 is provided with a first engaging structure 9231 located on the housing holder 923, and the frame 933 of the light quantity adjusting assembly 930 is provided with a second engaging structure 9232 adapted to the first engaging structure, wherein when the first engaging structure 9231 and the second engaging structure 9232 are adapted to be engaged together, the frame 933 of the light quantity adjusting assembly 930 is mounted on the housing holder 920, so that the light quantity adjusting assembly 930 is assembled to the light emitting end 9202 of the light turning assembly 920.
Preferably, as shown in fig. 26, in the periscopic camera module 91 according to the first modified embodiment of the present invention, the first engaging structure 9231 is implemented as a groove provided on the housing bracket 923, and the second engaging structure 9232 is implemented as a protrusion provided on the frame 933, so that the fixed assembly between the light quantity adjusting assembly 930 and the light turning assembly 920 is realized by inserting the protrusion on the frame 933 into the groove on the housing bracket 923, which not only can reduce the size of the periscopic camera module 91, but also can simplify the assembly and disassembly of the periscopic camera module 91.
More preferably, in order to further enhance the connection strength between the first latching structure 9231 and the second latching structure 9232, so that the light quantity adjusting assembly 930 is more firmly mounted to the housing bracket 923 of the light turning assembly 920, the adhesive layer 950 of the present invention may also be disposed between the first latching structure 9231 and the second latching structure 9232. For example, an adhesive is applied in the first fastening structure 9231 (i.e., the groove of the housing support 923), and then the first fastening structure 9231 and the second fastening structure 9232 are fastened to form the adhesive layer 950 between the first fastening structure 9231 and the second fastening structure 9232 after the adhesive is cured, so that the light amount adjusting assembly 930 is adhesively fastened to the housing support 923 of the light turning assembly 920, so that the light amount adjusting assembly 930 is firmly fixed to the light turning assembly 920.
It should be noted that, although the first latching structure 9231 and the second latching structure 9232 are sequentially implemented as a groove and a protrusion to realize the latching connection between the light quantity adjusting component 930 and the light turning component 920 in the periscopic camera module 91 as shown in fig. 26, the manner of latching is not limited thereto. For example, as shown in fig. 27, a second modified embodiment of the periscopic camera module 91 according to the above-described first embodiment of the present invention is illustrated, wherein the first snap-fit structure 9231 of the periscopic camera module 91 is implemented as a protrusion provided on the housing bracket 923, and the second snap-fit structure 9232 is implemented as a groove provided on the frame 933, so that the fixed assembly between the light quantity adjusting assembly 930 and the light turning assembly 920 is also achieved by the protrusion on the housing bracket 923 being inserted into the groove on the frame 933.
It should be noted that the light quantity adjusting component 930 of the periscopic camera module 91 is not limited to be assembled at the light outlet end 9202 of the light turning component 920, for example, in another example of the present invention, the light quantity adjusting component 930 may also be assembled at the light inlet end 9201 of the light turning component 920, so that the light rays propagating along the light sensing path 9120 first pass through the light quantity adjusting component 930 for adjusting the light quantity, then enter the light turning component 920 from the light inlet end 9201 for being turned, and then exit from the light outlet end 9202 for entering the module component 910 to be received and imaged by the light sensing component 912.
Fig. 28A and 28B show a third modified embodiment of the periscopic camera module 91 according to the first embodiment of the present invention, in which the adhesive layer 950 is located between the housing bracket 923 of the light turning assembly 920 and the frame 933 of the light quantity adjustment assembly 930, and the light quantity adjustment assembly 930 is located at the light inlet end 9201 of the light turning assembly 920, so as to firmly attach the light quantity adjustment assembly 930 to the light inlet end 9201 of the light turning assembly 920. Meanwhile, the adhesive layer 950 may be simultaneously located between the light exit end 9202 of the light redirecting unit 920 and the lens unit 911 of the module unit 910, so that the light amount adjusting unit 930, the light redirecting unit 920, and the module unit 910 are bonded together by the adhesive layer 950 to assemble the periscopic camera module 91 independently.
In this way, since the light quantity adjusting assembly 930 is independently assembled to the light entrance end 9201 of the light turning assembly 920 and the light turning assembly 920 is independently assembled to the module assembly 910, the light turning assembly 920 and the module assembly 910 can be assembled before the light quantity adjusting assembly 930 is assembled, so as to ensure high imaging quality of the periscopic camera module 91 by adjusting/adjusting the posture (i.e., position and posture) of the light turning assembly 920. Thereafter, in the process of assembling and adjusting the light quantity adjusting assembly 930, the light turning assembly 920 and the module assembly 910 do not need to be adjusted, which is beneficial to reducing the adjustment variables and improving the adjustment efficiency and accuracy of the light quantity adjusting assembly 930. Of course, the light quantity adjusting unit 930 is independently assembled to the light inlet end 9201 of the light turning unit 920, which further facilitates the detection and replacement of the light quantity adjusting unit 930, thereby reducing the maintenance cost.
It is noted that, as shown in fig. 28B, the adhesive layer 950 is disposed between the frame 933 of the light quantity adjusting assembly 930 and the housing bracket 923 of the light turning assembly 920, so that the light quantity adjusting assembly 930 is adhesively mounted to the light entrance end 9201 of the light turning assembly 920 through the adhesive layer 950.

It can be understood that, when the light quantity adjusting assembly 930 is adhesively mounted to the light exit end 9202 of the light turning assembly 920 through the adhesive layer 950, the thickness of the adhesive layer 950 also helps to adjust the relative position between the light turning assembly 920 and the light quantity adjusting assembly 930, so as to achieve the alignment between the center of the diaphragm hole 9300 of the light quantity adjusting assembly 930 and the center of the light exit surface of the light turning assembly 920.
Preferably, the thickness D of the adhesive layer 950 between the light amount adjusting member 930 and the light diverting member 920 is between 0.901mm and 0.92mm, that is, the range of the thickness D of the adhesive layer 950 is preferably implemented as 0.901mm < D < 0.92 mm.
More preferably, the thickness D of the adhesive layer 950 between the light amount adjusting member 930 and the light redirecting member 920 is between 0.903mm and 0.915mm, that is, the thickness D of the adhesive layer 950 is preferably implemented in a range of 0.903mm < D < 0.915 mm.
In addition, fig. 29 shows a fourth variant of the periscopic camera module 91 according to the first embodiment of the present invention, wherein the light quantity adjusting element 930 is directly fastened to the housing bracket 923 of the light turning element 920 and is located at the light entrance end 9201 of the light turning element 920. In other words, the light quantity adjusting unit 930 is directly and detachably assembled to the light inlet end 9201 of the light turning unit 920, which further facilitates the light quantity adjusting unit 930 to be replaced conveniently.
Illustratively, as shown in fig. 29, the light inlet 9201 of the light turning module 920 is provided with a first engaging structure 9231 located at the housing holder 923, and the frame 933 of the light quantity adjusting module 930 is provided with a second engaging structure 9232 adapted to the first engaging structure, wherein when the first engaging structure 9231 and the second engaging structure 9232 are adapted to be engaged together, the frame 933 of the light quantity adjusting module 930 is mounted on the housing holder 923 of the light turning module 920, so that the light quantity adjusting module 930 is assembled to the light inlet 9201 of the light turning module 920.
Preferably, as shown in fig. 29, in the periscopic camera module 91 according to the fourth modified embodiment of the present invention, the first engaging structure 9231 is implemented as a groove provided on the housing bracket 923, and the second engaging structure 9232 is implemented as a protrusion provided on the frame 933, so that the light quantity adjusting assembly 930 and the light steering assembly 920 are fixedly assembled by inserting the protrusion on the frame 933 into the groove on the housing bracket 923, which not only can reduce the size of the periscopic camera module 91, but also can simplify the assembly and disassembly of the periscopic camera module 91.
It should be noted that, although the first latching structure 9231 and the second latching structure 9232 are sequentially implemented as a groove and a protrusion to realize the latching connection between the light quantity adjusting component 930 and the light turning component 920 in the periscopic camera module 91 as shown in fig. 29, the manner of latching is not limited thereto.

Therefore, in order to debug the light quantity adjusting unit 930 before assembling the light redirecting unit 920, a periscopic camera module according to a second embodiment of the present invention is illustrated with reference to fig. 31A of fig. 29 of the specification. The periscopic camera module 91 according to the second embodiment of the present invention differs from the first embodiment of the present invention described above in that: the light quantity adjusting assembly 930 is directly assembled to the lens assembly 911 of the module assembly 910, and the light quantity adjusting assembly 930 is located on the photosensitive path 9120 of the photosensitive assembly 912 to adjust the quantity of light received by the photosensitive assembly 912 through the light quantity adjusting assembly 930 as well.
Illustratively, as shown in fig. 31A, the light quantity adjusting component 930 is directly adhered to the assembly housing 9113 of the lens component 911 through the adhesive layer 950, and the light quantity adjusting component 930 is located between the optical lens 9111 and the light turning component 920, so that the light rays propagating along the photosensitive path 9120 are firstly turned by the light turning component 920, then adjusted by the light quantity adjusting component 930, and finally received and imaged by the photosensitive chip 9121 of the photosensitive component 912 after being converged by the optical lens 9111.
It should be noted that, since the light quantity adjusting component 930 is directly adhered to the assembly housing 9113 of the lens assembly 911, before the light turning component 920 is assembled, the light quantity adjusting component 930 can be assembled on the assembly housing 9113 of the lens assembly 911 of the module assembly 910, so as to adjust the pose and the light quantity adjusting quality of the light quantity adjusting component 930 according to the image effect captured by the photosensitive chip 9121 of the photosensitive component 912, which is beneficial to reducing the difficulty of adjusting the light quantity adjusting component 930 and improving the accuracy of adjusting the light quantity adjusting component 930. Meanwhile, if the light amount adjusting unit 930 cannot meet the requirements after being debugged due to its own defects, the light amount adjusting unit 930 may be directly replaced with a new one, so as to avoid disassembling the light turning unit 920 and simplify the assembly process.
Further, as shown in fig. 31A, the adhesive layer 950 is disposed between the frame 933 of the light amount adjustment member 930 and the assembly housing 9113 of the lens assembly 911 to adhesively mount the light amount adjustment member 930 to the lens assembly 911 through the adhesive layer 950. Meanwhile, the thickness d of the adhesive layer 950 is implemented as the distance d between the frame 933 of the light amount adjustment member 930 and the assembly housing 9113 of the lens assembly 911, so that the distance between the light amount adjustment member 930 and the lens assembly 911 is controllably adjusted by the magnitude of the thickness d of the adhesive layer 950.
It is understood that the distance between the light amount adjustment member 930 and the lens member 911 (or the thickness d of the adhesive layer 950) can optically achieve a "vignetting" phenomenon relief, an increase in image brightness, and a sharper image, and also can achieve an adjustment of the relative position between the light amount adjustment member 930 and the lens member 911 such that the center of the diaphragm hole 9300 of the light amount adjustment member 930 is aligned with the optical axis of the optical lens 9111 of the lens member 911.
Preferably, the thickness d of the adhesive layer 950 between the light amount adjustment member 930 and the lens member 911 is between 0.901mm and 0.92mm, that is, the thickness d of the adhesive layer 950 is preferably implemented to have a value of 0.901mm ≦ d ≦ 0.92 mm.
More preferably, the thickness d of the adhesive layer 950 between the light amount adjustment member 930 and the lens member 911 is between 0.903mm and 0.915mm, that is, the range of the thickness d of the adhesive layer 950 is preferably implemented as 0.903mm ≦ d ≦ 0.915 mm.
Further, in one example of the present invention, as shown in fig. 31B, the adhesive layers 950 are correspondingly positioned at both left and right sides of the assembly housing 9113 of the lens assembly 911, so that the light amount adjustment assembly 930 is directly adhered to the assembly housing 9113 of the lens assembly 911 by the adhesive layers 950. In other words, the adhesive is disposed on the left and right sides of the assembly housing 9113 in a glue-drawing manner, and then the light amount adjusting component 930 is correspondingly attached to the assembly housing 9113 of the lens component 911, so that the pose and the light amount adjusting quality of the light amount adjusting component 930 are adjusted according to the photographed image effect before the adhesive is cured, which is helpful for improving the debugging accuracy of the light amount adjusting component 930.
Of course, in another example of the present invention, as shown in fig. 31C, the adhesive layers 950 are located at left and right sides and a bottom side of the assembly housing 9113 of the lens assembly 911, respectively, so that the light amount adjusting assembly 930 is securely adhered to the assembly housing 9113 of the lens assembly 911 by the adhesive layers 950. In other words, the adhesives are firstly disposed on the left and right sides and the bottom side of the assembly housing 9113 in a glue-drawing manner, and then the light amount adjusting components 930 are correspondingly attached to the assembly housing 9113 of the lens assembly 911, so that after the adhesives are cured, the adhesive layers 950 disposed on the left and right sides and the bottom side of the assembly housing 9113 are formed, which is helpful for increasing the adhesive area of the adhesive layers 950, and further enhancing the adhesive strength between the light amount adjusting components 930 and the lens assembly 911. In addition, the adhesive layers 950 located on the left, right, and bottom sides of the assembly housing 9113 of the lens assembly 911 also contribute to reducing the thickness of the periscopic camera module 91.
It should be noted that fig. 32 shows a first modified embodiment of the periscopic camera module 91 according to the second embodiment of the present invention, wherein the light quantity adjusting component 930 is directly fastened to the assembly housing 9113 of the lens assembly 911, and the light quantity adjusting component 930 is located between the optical lens 9111 and the light turning component 920. In other words, the present invention directly detachably assembles the light quantity adjusting component 930 to the assembly housing 9113 of the lens assembly 911, which further helps to reduce the difficulty in adjusting and replacing the light quantity adjusting component 930.
Illustratively, as shown in fig. 32, the assembly housing 9113 of the lens assembly 911 is provided with a first snap structure 9231, and the frame 933 of the light amount adjusting assembly 930 is provided with a second snap structure 9232 adapted to the first snap structure 9231, wherein when the first snap structure 9231 and the second snap structure 9232 are adapted to be snapped together, the frame 933 of the light amount adjusting assembly 930 is mounted on the assembly housing 9113 of the lens assembly 911, so that the light amount adjusting assembly 930 is detachably assembled to the assembly housing 9113 of the lens assembly 911.
In particular, as shown in fig. 32, in the periscopic camera module 91 according to this modified embodiment of the present invention, the first engagement structure 9231 is implemented as a groove provided in the assembly housing 9113, and the second engagement structure 9232 is implemented as a protrusion provided in the frame 933, so as to achieve fixed assembly between the light amount adjustment assembly 930 and the lens assembly 911 of the module assembly 910 by inserting the protrusion on the frame 933 into the groove on the assembly housing 9113, which not only enables reduction in size of the periscopic camera module 91, but also enables simplification of attachment and detachment of the periscopic camera module 91.
It should be noted that, although the first latching structure 9231 and the second latching structure 9232 are sequentially implemented as a groove and a protrusion to realize the latching connection between the light quantity adjusting component 930 and the lens component 911 in the periscopic camera module 91 as shown in fig. 32, this is only an example, and the latching manner mentioned in the present invention is not limited thereto. For example, as shown in fig. 33, a second modified embodiment of the periscopic camera module 91 according to the above-described second embodiment of the present invention is illustrated, in which the first snap-fit structure 9231 of the periscopic camera module 91 is implemented as a protrusion provided on the assembly housing 9113, and the second snap-fit structure 9232 is implemented as a groove provided on the frame 933, so that fixed assembly between the light amount adjustment member 930 and the lens member 911 can be also achieved by inserting the protrusion on the assembly housing 9113 into the groove on the frame 933.
Of course, in other examples of the present invention, the light amount adjusting component 930 may also be directly welded to the lens component 911 of the module component 910, so as to mount the light amount adjusting component 930 to the lens component 911 more firmly, which is not described in detail herein.
Fig. 34 shows a third modified embodiment of the periscopic camera module 91 according to the second embodiment of the present invention, in which the light quantity adjusting assembly 930 is directly assembled to the optical lens 9111 of the lens assembly 911 so as to keep the light quantity adjusting assembly 930 better aligned with the photosensitive path 9120 of the photosensitive assembly 912.
Specifically, as shown in fig. 34, the optical lens 9111 may include a first lens group 91111 and a second lens group 91112, wherein the light quantity adjusting assembly 930 is disposed between the first lens group 91111 and the second lens group 91112, and the second lens group 91112 is disposed between the light quantity adjusting assembly 930 and the photosensitive assembly 912, such that the light deflected by the light deflecting assembly 920 passes through the first lens group 91111, the light quantity adjusting assembly 930 and the second lens group 91112 in sequence, and then is received by the photosensitive chip 9121 of the photosensitive assembly 912 for imaging. It is to be understood that the first and second lens groups 91111 of the optical lens 9111 can include one or more lenses for converging light rays passing through the optical lens 9111.
Preferably, as shown in fig. 34, the optical lens 9111 further includes a lens barrel 91113, wherein the first lens group 91111, the light quantity adjusting assembly 930 and the second lens group 91112 are assembled in the lens barrel 91113 in sequence so as to keep the first lens group 91111 and the second lens group 91112 coaxial, and the center of the stop hole 9300 of the light quantity adjusting assembly 930 is located on the optical axis of the first lens group 91111 and the second lens group 91112, which helps to improve the imaging quality of the periscopic camera module 91. Meanwhile, the lens barrel 91113 of the optical lens 9111 is assembled to the focus actuator 9112, so that the lens barrel 91113 is driven by the adjustment actuator 9112 to drive the first lens group 91111, the second lens group 91112 and the light quantity adjusting assembly 930 to move along the photosensitive path 9120, so as to prevent the light quantity adjusting assembly 930 from affecting the focusing effect of the periscopic imaging module 91.
It should be noted that although the optical lens 9111 in the periscopic camera module 91 shown in fig. 34 only includes one lens barrel 91113, it is only an example, and the number of the lens barrels 91113 mentioned in the present invention is not limited thereto. For example, as shown in fig. 35, a fourth modified embodiment of the periscopic camera module 91 according to the above-mentioned second embodiment of the present invention is illustrated, wherein the optical lens 9111 of the periscopic camera module 91 may include a first barrel 91114 and a second barrel 91115, wherein the first lens group 91111 is assembled to the first barrel 91114, and the second lens group 91112 is assembled to the second barrel 91115. Meanwhile, the light quantity adjusting assembly 930 is assembled between the first barrel 91114 and the second barrel 91115 to ensure that the light quantity adjusting assembly 930 is positioned between the first lens group 91111 and the second lens group 91112.
It is to be noted that, just because the first and second lens groups 91111, 91112 are assembled to the first and second barrels 91114, 91115, respectively, and the first and second barrels 91114, 91115 are independent from each other, the focus actuator 913 of the lens assembly 911 of the present invention can achieve the focusing effect of the periscopic camera module 91 by driving the first barrel 91114 and/or the second barrel 91115.
For example, the light amount adjusting assembly 930 may be, but is not limited to, mounted on the first barrel 91114 and/or the second barrel 91115 of the optical lens 9111 by means such as bonding or snap-fitting, and the description of the invention is omitted here.

Fig. 36 shows a fifth modified embodiment of the periscopic camera module 91 according to the second embodiment of the present invention, in which the light quantity adjusting assembly 930 is integrally formed with the focus actuator 9112 of the lens assembly 911, that is, the light quantity adjusting assembly 930 is integrally connected with the lens assembly 911 to form an actuator having a function of adjusting the quantity of incoming light, thereby achieving the focusing effect and the quantity of incoming light adjustment.
It is noted that the focus actuator 9112 of the present invention can comprise a drive motor and a drive housing. The drive motor may include a magnet mounted on a lens barrel of the optical lens 9111 and a coil mounted on the drive housing, and the position of the magnet and the position of the coil correspond to each other. The drive housing has a recessed aperture for receiving the optical lens 9111. It is understood that the drive motor may be implemented as, but not limited to, a voice coil motor or a piezoelectric motor. In another example of the present invention, the coil may be attached to a lens barrel of the optical lens 9111, and the magnet may be attached to the drive housing.
Illustratively, in this modified embodiment of the present invention, the frame 933 of the light amount adjusting assembly 930 is integrally connected to the driving housing of the focus actuator 9112, so that the light amount adjusting assembly 930 and the focus actuator 9112 have an integrated structure. In other words, the light amount adjusting assembly 930 is integrally mounted to the focus actuator 9112 to maximize the coupling strength of the light amount adjusting assembly 930 to the focus actuator 9112. Of course, in other examples of the present invention, the light amount adjusting assembly 930 may be mounted to the driving housing of the focus driver 9112 by means of adhesion and/or snap-fitting.
It should be noted that, in the second embodiment of the present invention, when the periscopic camera module 91 is assembled, the light quantity adjusting assembly 930 and the module assembly 910 may be pre-positioned by a capturing tool such as a clamp or a suction cup, so that the center line of the diaphragm hole 9300 of the light quantity adjusting assembly 930 is substantially aligned (or approximately aligned) with the optical axis of the optical lens 9111 of the lens assembly 911 of the module assembly 910, so that the photosensitive assembly 912 can capture an image of the target through the light quantity adjusting assembly 930; adjusting the position of the light quantity adjusting component 930 according to the image quality (such as the SFR value of the image) so as to improve the degree of alignment between the light quantity adjusting component 930 and the optical axis of the optical lens 9111; thereafter, the control effect of the light amount adjusting unit 930 is adjusted to test whether the SFR value of the image reaches the expected SFR value during the adjustment of the light amount adjusting unit 930 in the light amount adjusting range, so as to facilitate the replacement of the light amount adjusting unit 930 which fails the test before the light redirecting unit 920 is assembled.
Then, in case the light amount adjustment member 930 meets the requirement, the light redirecting member 920 may be further pre-positioned such that the center lines of the light redirecting member 920, the light amount adjustment member 930, and the module member 910 are substantially aligned; and the position of the light-turning component 920 is adjusted according to the quality of the image (i.e. the shooting effect) shot by the photosensitive component 912, so as to further improve the alignment degree between the center of the light-emitting end 9201 of the light-turning component 920 and the optical axis of the optical lens 9111; finally, after the adjustment and adjustment, the light turning assembly 920, the light quantity adjusting assembly 930 and the module assembly 910 are fixed in position to complete the manufacture of the periscopic camera module 91.
