[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0032] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0033] See also Figures 1 to 4An embodiment of the present application provides a shading assembly, which includes: a bracket 100, having a zoom channel 101; a transmission assembly 200, arranged on the bracket 100 and located in the zoom channel 101; a prism group 300, movably arranged in the zoom channel 101 and connected to the transmission assembly 200; and a shading member 400, mounted on the bracket 100 through the transmission assembly 200 and located above the prism group 300; the prism group 300 is driven to move along the zoom channel 101, and the shading member 400 is driven by the transmission assembly 200 to move in the zoom channel 101 in the opposite direction to the prism group to block stray light in the zoom channel 101.

[0034] In this embodiment, a transmission assembly 200 is provided on the inner side of the bracket 100 to connect the prism group 300 and the shading member 400, so that the shading member 400 can be moved in the opposite direction while the prism group 300 is moved, thereby blocking the unnecessary stray light of the prism group 300, reducing the interference of external light on the prism group 300, and improving the camera quality; and, compared with the layout of the traditional shading structure in which the pulley thereon is slidably connected to the slide groove on the bracket 100, the transmission assembly 200 is not easily worn, and can effectively avoid the problem of the shading member 400 getting stuck during the movement process, and has longer wear resistance and service life, which can effectively improve the smoothness of the zoom process and the zoom effect of the camera module, thereby improving the performance of the camera module.

[0035] Specifically, the shading assembly is configured as a composite component comprising at least a bracket 100, a transmission assembly 200, a prism group 300, and a shading member 400. The bracket 100 may be a nearly rectangular frame structure for assembly inside the camera module. Enclosures are formed on both sides of the zoom channel 101. This not only provides a sealed environment for the prism group 300, reduces stray light interference inside the camera module, and improves the light propagation effect of the prism group 300, but also provides support for the shading member 400, improving the stability and reliability of the zoom shading operation of the shading member 400. The transmission assembly 200 may be a gear rack transmission structure for transmitting the movement of the prism group 300 side to the shading member 400 side, so as to achieve synchronous movement of the prism group 300 and the shading member 400 during the zoom process, thereby improving the response speed and user experience of the camera module. The prism group 300 can be a triangular lens structure, which is used to change the light propagation path to redirect the external light source and transmit it to the AF prism 10 mounted on the AF motor in the camera module, and finally transmit it to the sensor 20 in the camera module to form an image; the prism group 300 can be movably set in the zoom channel 101 to realize AB focal length zoom photography in the camera module, which can meet the needs of shooting objects at different focal lengths and has a wide range of applications, such as Figure 6As shown. The light shielding member 400 can be a one-piece plate structure, which can be connected and fastened to the transmission assembly 200 by fasteners such as screws / bolts to improve the connection tightness between the two. The light shielding member 400 can block unnecessary external light sources, preventing them from entering the zoom channel 101 and contaminating the light transmitted by the prism group 300, thereby improving the imaging quality on the side of the sensing sensor 20. The light shielding member 400 provided in this example is connected to the bracket 100 and the prism group 300 through the transmission assembly 200, which can achieve synchronous movement of the prism group 300 and the light shielding member 400, shortening the response time of the camera module, increasing the speed of forming the imaging environment, and improving image capture efficiency. In addition, the assembly of the transmission assembly 200 and the bracket 100 is simple, and the preparation of the light shielding member 400 is simple, which can effectively reduce production costs and realize mass production.

[0036] In one example, the prism group 300 can be driven by the cooperation of FPC (flexible circuit) and conductor. For example, the FPC can be processed into a sheet structure and made to constitute part of the bracket 100. Then, the conductor is arranged at the bottom of the prism group 300 and the conductor is located in the magnetic field formed by the energized FPC. In this way, when alternating current is passed through the FPC, a changing magnetic field will be generated around it, and an induced current will be generated in the conductor located therein. The induced current will cause the conductor to move under the action of the Ampere force and drive the prism group 300 connected thereto to move, thereby realizing the zoom of the camera module. Of course, in other embodiments, the prism group 300 can also be driven and moved directly by a micro motor, and the overall structure is simpler. The driving method of the prism group 300 is not limited here, and the operator can choose according to actual needs, as long as it is ensured that the prism group 300 can move.

[0037] like Figure 1 and Figure 2 As shown, in a possible embodiment, the transmission assembly 200 includes a first rack 210, a gear 220 and a second rack 230. The first rack 210 extends along the length direction Y of the bracket 100 and is meshed and connected to the bottom of the gear 220; the second rack 230 extends along the length direction Y of the bracket 100 and is meshed and connected to the top of the gear 220. The gear 220 is rotatably connected to the bracket 100, the prism group 300 is connected to the first rack 210, and the shading member 400 is connected to the second rack 230.

[0038] In this embodiment, the specific configuration of the transmission assembly 200 is optimized. Specifically, the transmission assembly 200 is configured as a composite component comprising at least a first rack 210, a gear 220, and a second rack 230. The first rack 210 is a long, strip-shaped structure with serrations on its top. It can be a one-piece structure or a segmented structure arranged on the same horizontal line. It can be fixedly connected to the base of the prism assembly 300 via components such as connecting posts or blocks to synchronize with the movement of the prism assembly 300. The gear 220 can be a composite structure of a fixed shaft and an annular tooth portion. The fixed shaft can be inserted into the bracket 100 and at least partially extend out of the zoom channel 101. The axial direction of the fixed shaft is aligned with the width direction X of the bracket 100. The annular tooth portion is sleeved on the fixed shaft and can rotate about the fixed shaft. The lower portion of the annular tooth portion meshes with the upper serrations on the first rack 210, driving the gear 220 to rotate clockwise when the first rack 210 moves along the length direction Y of the bracket 100. The second rack 230 may be a long strip-shaped structure with lower serrations at the bottom, and may be an integrated structure to ensure the overall followability of the second rack 230. The top of the second rack 230 may be connected to the bottom of the light shielding member 400 by means of fasteners such as screws / bolts, so that the light shielding member 400 is arranged outside the zoom channel 101, thereby preventing interference with the light shielding member 400 by other components in the zoom channel 101 during movement and improving the smoothness of movement of the light shielding member 400. The lower serrations are meshed with the upper portion of the gear 220, so that when the first rack 210 moves along the longitudinal direction Y of the bracket 100, the gear 220 is driven to rotate clockwise, thereby driving the second rack 230 to move in the opposite direction along the longitudinal direction Y of the bracket 100, thereby achieving offset movement of the prism group 300 and the light shielding member 400, enabling the light shielding member 400 to block stray light at different focal lengths, and improving the imaging effect of the prism group 300. The transmission assembly 200 provided in this example has a compact fit with the shading member 400, the bracket 100 and the prism group 300, good wear resistance, long service life, smooth movement without jamming, and good zoom effect.

[0039] like Figure 2 As shown, in one possible embodiment, the bracket 100 is provided with a retaining hole 102, which extends along the width direction X of the bracket 100 and communicates with the zoom channel 101. With this arrangement, the retaining hole 102 can be used to lock the transmission assembly 200 with the bracket 100, thereby fixing the relative position of the prism assembly 300 and the light shielding member 400, reducing stray light interference during imaging, and improving the imaging quality of the camera module.

[0040] like Figure 2As shown, in a possible embodiment, there are at least two limiting holes 102, and the two limiting holes 102 are spaced apart and distributed in the length direction Y of the bracket 100. The transmission assembly 200 also includes a first limiting member 240, which is movably connected to the prism group 300 and can be inserted into the limiting hole 102 to lock the prism group 300 and the bracket 100.

[0041] In this embodiment, the specific configuration of the transmission assembly 200 is further optimized. Specifically, the transmission assembly 200 is configured as a composite component including at least a first rack 210, a gear 220, a second rack 230, and a first limiter 240. The first limiter 240 can be a shaft column structure, which is used to be inserted into the limiter hole 102 on the bracket 100 to achieve locking of the prism group 300 and the bracket 100, preventing the prism group 300 from continuing to move after reaching the specified position, improving its coordination with the light shielding member 400, and improving the zoom imaging effect; the first limiter 240 can achieve its plug-in and pull-out operation with the limiter hole 102 through a mechanical transmission structure, and can also achieve plug-in and pull-out operation through components such as a motor cylinder. The transmission assembly 200 provided in this example provides a more stable and reliable zoom operating environment.

[0042] like Figure 2 As shown, in a possible implementation, the transmission assembly 200 further includes a driving member 250 , the driving member 250 is connected to the prism assembly 300 , and the first limiting member 240 is connected to an output end of the driving member 250 .

[0043] In this embodiment, the specific configuration of the transmission assembly 200 is further optimized. Specifically, the transmission assembly 200 is configured as a composite component including at least a first rack 210, a gear 220, a second rack 230, a first stopper 240, and a driver 250. The driver 250 can be a drive motor that can be fixedly mounted on the base of the prism assembly 300 and can extend or retract in the width direction X of the bracket 100, thereby enabling the first stopper 240 to move back and forth in the width direction X of the bracket 100 and locking the prism assembly 300 with the bracket 100. The transmission assembly 200 provided in this example can promptly achieve intelligent locking between the prism assembly 300 and the bracket 100 after reaching the specified position, with higher drive control accuracy and better locking effect.

[0044] In one example, two driving members 250 can be provided, and the output ends of the two driving members 250 are arranged to face each other. In this case, two first limiting members 240 can be provided, and one first limiting member 240 is correspondingly connected to the output end of one driving member 250. There are at least four limiting holes 102, two of which are relatively arranged in the A focal length of the zoom channel 101. In this case, the first limiting members can be driven by the driving member 250 to be inserted into the corresponding limiting holes 102 to achieve the locking of the prism group 300 and the bracket 100 in the A focal length; the other two are relatively arranged in the B focal length of the zoom channel 101. In this case, the first limiting members 240 can be driven by the driving member 250 to be inserted into the corresponding limiting holes 102 to achieve the locking of the prism group 300 and the bracket 100 in the B focal length, thereby achieving zoom imaging of the camera module.

[0045] like Figures 1 to 6 As shown, in a possible embodiment, the bracket 100 includes at least two support arms 110, and the at least two support arms 110 are arranged opposite to each other and at intervals to enclose a zoom channel 101, the shading member 400 is mounted between the two support arms 110, and the transmission assembly 200 is arranged on the inner side of the two support arms 110.

[0046] In this embodiment, the specific configuration of the bracket 100 is optimized. Specifically, the bracket 100 is configured as a composite component including at least two support arms 110. The support arms 110 can be a plate-like structure that partially blocks the zoom channel 101 to reduce the interference of light inside the camera module on the prism group 300, further improving the imaging effect. The support arms 110 have a certain thickness in the width direction X of the bracket 100 to enhance the overall rigidity of the support arms 110, so that while being able to support the shading member 400 and the transmission assembly 200, they also provide a stable movement operating environment for the transmission assembly 200, preventing the transmission assembly 200 from shaking during movement and affecting the precise movement of the shading member 400, thereby improving the shading effect of the camera module.

[0047] like Figures 1 to 5 As shown, in a possible embodiment, a guide groove 103 is provided on the inner side of the support arm 110, and the shading member 400 includes a shading portion 410 and a guide portion 420, and the guide portion 420 is arranged on opposite sides of the shading portion 410 along the width direction X of the bracket 100, and the guide portion 420 is movably inserted in the guide groove 103, and the shading portion 410 is connected to the transmission assembly 200.

[0048] In this embodiment, the specific configuration of the light shielding piece 400 and the connection mode thereof with the support 100 are optimized. Specifically, a guide groove 103 is arranged on the inner side wall of the top end of the support arm 110, and the guide groove 103 extends along the length direction Y of the support 100; meanwhile, the light shielding piece 400 is configured as a combined component including at least a light shielding part 410 and a guide part 420, and the light shielding part 410 and the guide part 420 can be integrally formed to reduce the processing difficulty and processing cost and improve the overall performance of the light shielding piece 400; the light shielding part 410 can be a flat plate and can at least shield the zoom channel 101 in the width direction X of the support 100; the guide part 420 can be an L-shaped folded edge, and the guide part 420 is connected to the two sides of the light shielding part 410 to form side wings, and the guide part 420 can be movably inserted into the corresponding guide groove 103, so as to realize the movement guidance of the light shielding piece 400 and improve the movement accuracy of the light shielding piece 400; meanwhile, the structural stability of the light shielding piece 400 and the support 100 during the movement is improved, the overall structural reliability of the light shielding assembly is improved, and the zoom operation reliability is improved.

[0049] As shown in Figures 1 to 4 , in a possible implementation, the support 100 further includes a second limiting piece 120, and the second limiting piece 120 is arranged at the first end of the guide groove 103 and extends along the thickness direction Z of the support 100.

[0050] In this embodiment, the specific configuration of the support 100 is further optimized. Specifically, the support 100 is configured as a combined component including at least two support arms 110 and a second limiting piece 120, and the second limiting piece 120 can be a columnar or block-shaped protrusion arranged at the first end of the guide groove 103, used to limit the position of the guide part 420, prevent the light shielding piece 400 from being detached from the support 100, and improve the cooperation reliability of the light shielding piece 400 and the support 100; meanwhile, the gear 220 can also be prevented from being loosened from the first rack 210, the structural stability and reliability of the transmission assembly 200 are improved, and the movement reliability of the zoom operation is improved. The support 100 provided in this example can realize the stopping of the light shielding piece 400 in the length direction Y of the support 100, prevent the light shielding piece 400 from being detached from the support 100 in this direction, and has high stability and strong zoom movement reliability.

[0051] As shown in Figures 1 to 3 , in a possible implementation, the support 100 further includes a third limiting piece 130, and the third limiting piece 130 is arranged between the two support arms 110 and located at the second end of the guide groove 103.

[0052] In this embodiment, the specific configuration of the support 100 is further optimized. Specifically, the support 100 is configured as a combined member including at least two support arms 110 and a third limiting piece 130. The third limiting piece 130 can be a long strip-shaped sheet in a nearly U shape, which can be inserted on the support arm 110 to achieve the connection and fastening of the third limiting piece 130 and the support 100. The third limiting piece 130 extends the light shielding piece 400 in the thickness direction Z of the support 100, which can achieve the stopping of the light shielding piece 400 at the second end of the guide groove 103, prevent the light shielding piece 400 from being detached from the support 100 at the second end side of the guide groove 103, and improve the cooperation reliability of the light shielding piece 400 and the support 100. In addition, the third limiting piece 130 can block stray light in the thickness direction Z of the support 100, reduce the imaging interference of external light on the prism group 300, and improve the imaging quality.
