Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a prism assembly, an optical image stabilization assembly, a camera, and an electronic device. Background Technology

[0002] Most smartphones today are equipped with cameras for users to take pictures or make video calls. With increasing user demands and manufacturers' continuous improvements, telephoto cameras are increasingly being used in smartphones, enabling functions such as long-distance or telephoto shooting. However, to achieve a longer focal length or higher focal range, the length of the camera needs to be increased. But with the trend towards thinner and lighter smartphones, a larger camera may exceed the thickness of the smartphone, resulting in the camera protruding from the phone's thickness. This makes the camera more susceptible to damage when the smartphone is subjected to impacts or drops.

[0003] Therefore, some smartphones are now incorporating prisms. Simply put, this allows the camera to be positioned vertically within the smartphone. Furthermore, the prism can deflect the light path of the camera, thus freeing the camera's length from the limitations of the smartphone's thickness. However, in current smartphones, prisms are typically fixed directly inside with adhesive. These prisms are prone to breakage under impact, and the adhesive can easily detach. Therefore, the structures used to fix prisms still require significant optimization. Summary of the Invention

[0004] This application provides a prism assembly, an optical image stabilization assembly, a camera, and an electronic device that can ensure the structural strength of the prism and facilitate the fixing of the prism.

[0005] On one hand, this application provides a prism assembly, including a prism, N fixing plates, and a mounting bracket. The prism has N positioning surfaces. Each fixing plate has a first fixing surface and a second fixing surface. The mounting bracket has N mounting surfaces, and the N positioning surfaces, N fixing plates, and N mounting surfaces are arranged in a one-to-one correspondence, where N is an integer greater than or equal to 1. That is, the prism and the mounting bracket are fixedly connected by the fixing plates. Specifically, in the corresponding positioning surface, fixing plate, and mounting surface, the first fixing surface of the fixing plate can be fixedly connected to the positioning surface, and the second fixing surface of the fixing plate can be fixedly connected to the mounting surface, thereby realizing the fixed connection between the prism and the mounting bracket. In the prism assembly provided by this application, the prism and the mounting bracket can be fixedly connected by the fixing plates, so that the fixing plates can effectively protect the prism. In addition, the fixing plates also facilitate the improvement of the connection strength between the prism and the mounting bracket, effectively preventing the risk of the prism falling off the mounting bracket.

[0006] In one possible implementation, the shapes of the fixing plate and the fixing plate can be the same in the corresponding positioning surface and fixing plate. Alternatively, it can be understood that the shape and contour of the first fixing surface in the fixing plate can be the same as that of the corresponding positioning surface, so that the fixing plate can effectively protect the prism. Of course, in other embodiments, the shapes of the first fixing surface in the fixing plate and the corresponding positioning surface can be different. Alternatively, the area of ​​the first fixing surface can be larger or smaller than the area of ​​the corresponding positioning surface. This application does not limit this.

[0007] In one implementation, the prism and the fixing plate can be fixedly connected by adhesive bonding. For example, the prism assembly may further include a first adhesive layer, which may be located between at least one corresponding positioning surface and the first fixing surface of the fixing plate. That is, at least one corresponding positioning surface and the first fixing surface of the fixing plate can be fixedly connected by the first adhesive layer.

[0008] In addition, the first fixing surface of at least one fixing piece may have a first adhesive filling groove, and at least a portion of the first adhesive layer disposed between the first fixing surface and the corresponding positioning surface of the at least one fixing piece may be filled in the first adhesive filling groove. The first adhesive filling groove can effectively increase the bonding area between the first fixing surface and the first adhesive layer, thereby improving the connection strength between the first fixing surface and the first adhesive layer and preventing defects such as delamination.

[0009] In one implementation, the fixing plate and the mounting bracket can also be fixedly connected by adhesive bonding. For example, the prism assembly may further include a second adhesive layer, which may be located between the second fixing surface and the mounting surface of at least one corresponding fixing plate. That is, the second adhesive layer can be used to achieve a fixed connection between the second fixing surface and the mounting surface of at least one corresponding fixing plate.

[0010] In addition, the second fixing surface of at least one fixing piece may have a second adhesive filling groove, and at least a portion of the second adhesive layer disposed between the second fixing surface of the at least one fixing piece and the corresponding mounting surface fills the second adhesive filling groove. The second adhesive filling groove can effectively increase the bonding area between the second fixing surface and the second adhesive layer, thereby improving the connection strength between the second fixing surface and the second adhesive layer and preventing defects such as delamination.

[0011] In addition, at least one mounting surface may have a third adhesive filling groove, and at least a portion of the second adhesive layer disposed between the at least one mounting surface and the second fixing surface of the corresponding fixing piece may be filled in the third adhesive filling groove. The third adhesive filling groove can effectively increase the bonding area between the mounting surface and the second adhesive layer, thereby improving the connection strength between the mounting surface and the second adhesive layer and preventing defects such as delamination.

[0012] In one implementation, the second fixing surface of at least one fixing piece may have a positioning protrusion, and the mounting surface corresponding to the at least one fixing piece may have a positioning groove, with the positioning protrusion located within the positioning groove. During assembly of the fixing piece and the mounting bracket, the relative position between the fixing piece and the mounting bracket can be ensured by the cooperation of the positioning protrusion and the positioning groove, thereby effectively improving the assembly accuracy between the fixing piece and the mounting bracket and also enhancing the convenience of installation.

[0013] Of course, in specific implementation, at least a portion of the second adhesive layer, which is set between the mounting surface with the positioning groove and the second fixing surface of the corresponding fixing piece, can be filled in the positioning groove to increase the bonding area between the second adhesive layer and the mounting surface. In addition, it can also prevent the positioning protrusion from generating relative displacement in the positioning groove.

[0014] In specific configurations, one end of the positioning groove can extend to the edge of the mounting surface. When assembling the fixing plate and the mounting bracket, the positioning protrusion can slide into the positioning groove from one end, thereby effectively reducing assembly difficulty.

[0015] In one implementation, the positioning protrusion can also be an elastic structure, and the positioning groove can also have a recess. When the positioning protrusion and the recess elastically engage, the relative fixation between the fixing piece and the mounting bracket can be achieved.

[0016] When setting up a prism, the prism can be a cylindrical structure, and at least one end face of the prism can have a positioning surface. Furthermore, the number of fixing plates and mounting surfaces can be the same as the number of positioning surfaces, and each positioning surface is fixedly connected to its corresponding positioning surface via a corresponding fixing plate. Of course, this application does not limit the number or placement of positioning surfaces. Additionally, the prism can also be of shapes other than cylindrical.

[0017] In one implementation, the mounting bracket may have an adhesive-blocking structure located within the projection area of ​​the prism's light-processing surface. This adhesive-blocking structure prevents the first or second adhesive layer from overflowing onto the prism's light-processing surface, thus ensuring the prism's cleanliness.

[0018] In a specific configuration, the adhesive barrier structure may include grooves or protrusions, and this application does not limit the specific structure of the adhesive barrier structure.

[0019] On the other hand, this application also provides an optical image stabilization component, including a stator, a mover, and a prism assembly in any of the above possible designs. The mover is movably mounted on the stator, and the mounting bracket in the prism assembly is fixedly connected to the mover. When the mover moves relative to the stator, it can drive the mounting bracket in the prism assembly to move, thereby driving the prism to move, which can change the propagation direction of light in the electronic device to achieve the effect of optical image stabilization.

[0020] In one implementation, the optical image stabilization component may further include a protective protrusion, which can be fixed to the surface of the mounting bracket. During transportation or assembly processes, the protective protrusion effectively protects the prism or other components within the optical image stabilization component, thereby enhancing its safety.

[0021] In specific configurations, the optical image stabilization assembly may also include a protective housing, which can be fixedly connected to the stator. Protective protrusions may also be provided within the movable gap between the mounting bracket and the protective housing to prevent hard impacts between them.

[0022] On the other hand, embodiments of this application also provide a camera, including a housing, a lens, an image sensor, and the aforementioned optical image stabilization component. The optical image stabilization component, the lens, and the image sensor can be sequentially arranged within the housing along the light propagation path.

[0023] On the other hand, embodiments of this application also provide an electronic device, including a processor, a digital-to-analog converter (DAC), and the aforementioned camera. The image sensor in the camera can be communicatively connected to the processor via the DAC. Specifically, the DAC can be communicatively connected to the image sensor to convert electrical signals from the image sensor into digital signals. The processor can be communicatively connected to the DAC and can perform calculations and other processing on the digital signals.

[0024] In practical applications, electronic devices can be displays, smartphones, televisions, cameras, or laptops, etc. This application does not limit the specific type of electronic device. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0037] To facilitate understanding of the prism assembly provided in the embodiments of this application, its application scenarios will be introduced first below.

[0038] Prism components can typically be used in various types of electronic devices. For example, electronic devices may include displays, smartphones, televisions, cameras, or laptops. In the embodiments provided in this application, a smartphone is used as an example for detailed description.

[0039] like Figure 1 The diagram shows a cross-sectional view of a conventional smartphone along its thickness. The smartphone may include a housing 01, a display screen 02, a camera 100, and a processor (not shown). The display screen 02 may be disposed on one side of the housing 01, and the camera 100 may be disposed inside the housing 01. The housing 01 has a light-transmitting hole 011, allowing external light or objects to enter the camera 100 through the light-transmitting hole 011, enabling the camera 100 to acquire image information from the outside world for the user to take photos or videos using the smartphone.

[0040] The camera 100 may include a prism 11, a lens 101, and an image sensor 102. The working principle of the camera 100 is roughly as follows: light or objects (as shown by the dotted arrow in the figure) propagate to the prism 11, where their propagation direction undergoes a change of approximately 90°. This light is then processed by the lens 101 and finally projected onto the image sensor 102, which converts the light signal into an electrical signal.

[0041] Figure 2 The diagram shows a cross-sectional view of another existing smartphone; please refer to it for further information. Figure 1 and Figure 2 Through comparison, it was found that in Figure 2 Since no prism 11 is provided, the length direction of the camera 100 (or lens 101) needs to be consistent with the thickness direction of the smartphone. Therefore, the thickness of the smartphone will restrict the length of the camera 100 (or lens 101).

[0042] Therefore in Figure 1 In the structure shown, after setting the prism 11, the camera 100 can be vertically positioned inside the housing 01 so that the length of the camera 100 can be perpendicular to the thickness direction of the smartphone, thereby avoiding the limitation of the length of the camera 100 by the thickness of the smartphone.

[0043] In practical applications, lens 101 may include multiple lenses, which are arranged sequentially along the light propagation path. These lenses may include filters, convex lenses, and concave lenses. Filters can filter light of specific wavelengths (such as infrared light), thereby improving the quality of light transmitted to image sensor 102 and contributing to improved image quality. Convex lenses can focus light. Conversely, concave lenses can diverge light. In practical applications, the type, number, and arrangement of lenses included in lens 101 can be adaptively adjusted according to actual needs; this application does not limit this.

[0044] Furthermore, the length of the lens 101 significantly affects the focal length of the camera 100. For example, a longer lens 101 allows the camera 100 to have a longer focal length, enabling telephoto shooting at greater distances. However, due to the thickness limitations of smartphones, a longer camera 100 will protrude from the surface of the casing 01, increasing the risk of damage. Additionally, it will compromise the smoothness of the smartphone's appearance, negatively impacting the user experience.

[0045] Therefore, as Figure 1In the embodiment shown, by setting the prism 11, the camera 100 can be vertically positioned inside the housing 01 to avoid the length of the camera 100 being limited by the thickness of the smartphone.

[0046] In practical applications, smartphones may include electronic components such as processors and digital-to-analog converters (DACs). Specifically, the DAC can communicate with the image sensor 102 to convert electrical signals from the image sensor 102 into digital signals. The processor can also communicate with the DAC and perform calculations and other processing on the digital signals obtained from the DAC to generate corresponding image data.

[0047] Based on the above Figure 1 The structure shown has two main drawbacks. First, in practical applications, the prism 11, typically made of transparent materials such as glass or crystal, is fragile. Second, the prism 11 used in smartphones is small, making it difficult to fabricate connecting structures such as protrusions or grooves on its surface. Therefore, the prism 11 is currently usually fixed directly to the inside of the casing 01 with adhesive. When the smartphone is dropped or impacted, there is a risk of the prism detaching from the adhesive, making the prism 11 easily damaged. Furthermore, during adhesive application, the limited space inside the phone's casing 01 can easily cause adhesive overflow, potentially contaminating the surface of the prism 11 or even spilling onto other internal components of the smartphone, causing contamination of the prism 11 and other structural parts.

[0048] Therefore, the embodiments of this application are as follows: Figure 1 Based on the smart electronic device with a prism assembly shown, a prism assembly is provided that ensures the structural strength of the prism and facilitates its fixation. This prism assembly can be applied to any electronic device with camera functionality, i.e., equipped with a camera or lens, such as a smartphone with a camera. This application does not specifically limit the specific application scenarios of the proposed prism assembly.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” and “the” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, “at least one” means one, two, or more.

[0051] References to "one embodiment" and similar terms used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," and "in other embodiments" appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0052] like Figure 3 and Figure 4 As shown, in one embodiment provided in this application, the prism assembly 10 may include a prism 11, a fixing plate, and a mounting bracket 13. The prism 11 has two positioning surfaces, namely positioning surface 111a and positioning surface 111b. Correspondingly, there are two fixing plates, namely fixing plate 12a and fixing plate 12b. Fixing plate 12a has a first fixing surface 121a and a second fixing surface 122a, and fixing plate 12b has a first fixing surface 121b and a second fixing surface 122b. The mounting bracket 13 has a mounting surface 13a and a mounting surface 13b. The first fixing surface 121a of fixing plate 12a is fixedly connected to the positioning surface 111a, and the second fixing surface 122a of fixing plate 12a is fixedly connected to the mounting surface 13a. The first fixing surface 121b of fixing plate 12b is fixedly connected to the positioning surface 111b, and the second fixing surface 122b of fixing plate 12b is fixedly connected to the mounting surface 13b. In the prism assembly 10 provided in this application, the prism 11 and the mounting bracket 13 are fixedly connected by fixing plates 12a and 12b. This allows the fixing plates 12a and 12b to effectively protect the prism 11. Furthermore, the fixing plates 12a and 12b also enhance the connection strength between the prism 11 and the mounting bracket 13, effectively preventing the prism 11 from detaching from the mounting bracket 13. During assembly, the prism 11 can be fixedly connected to the fixing plates 12a and 12b first, and then the fixing plates 12a and 12b can be fixedly connected to the mounting bracket 13. Alternatively, the fixing plates 12a and 12b can be fixedly connected to the mounting bracket 13 first, and then the prism 11 can be fixedly connected to the fixing plates 12a and 12b, thus providing greater flexibility in the installation process.

[0053] In practical implementation, the structural shape of prism 11 can be diverse. For example, as... Figure 3 and Figure 4 As shown in the embodiments provided in this application, the prism 11 can be a columnar structure, and the cross-section of the prism 11 is approximately triangular. Alternatively, it can be understood as... Figure 3 and Figure 4 The prism 11 shown is a triangular prism. The two end faces of the prism 11 serve as positioning surfaces 111a and 111b, respectively, and the three side faces are light processing surfaces, namely light processing surface 112a, light processing surface 112b, and light processing surface 112c.

[0054] In actual use, light can enter the prism 11 through the light processing surface 112a, be reflected by the light processing surface 112c, and exit through the light processing surface 112b.

[0055] It is understood that in the embodiments provided in this application, the prism 11 is specifically described as a triangular prism, and the prism 11 has two positioning surfaces: positioning surface 111a and positioning surface 111b. It is also understood that in specific applications, one end face of the prism 11 may have a positioning surface, while the other end face may be suspended. For example, positioning surface 111a or positioning surface 111b may be omitted. Correspondingly, the fixing piece 12a fixedly connected to positioning surface 111a and the mounting surface 13a in the mounting bracket 13 may also be omitted. Alternatively, the fixing piece 12b fixedly connected to positioning surface 111b and the mounting surface 13b in the mounting bracket 13 may also be omitted.

[0056] In other words, in practical applications, the prism 11 can have N positioning surfaces, and correspondingly, the prism assembly 10 can include N fixing pieces, and the mounting bracket 13 can also have N mounting surfaces, where N is an integer greater than or equal to 1. The N positioning surfaces, N fixing pieces, and N mounting surfaces are arranged in a one-to-one correspondence, and in each of the corresponding positioning surfaces, fixing pieces, and mounting surfaces, the positioning surface is fixedly connected to the first fixing surface, and the mounting surface is fixedly connected to the second fixing surface. Alternatively, it can be understood that the number of fixing pieces and mounting surfaces can be the same as the number of positioning surfaces, and each positioning surface is fixedly connected to its corresponding positioning surface through a corresponding fixing piece.

[0057] Of course, in other embodiments, the cross-section of the prism 11 may also be rectangular, pentagonal or other polygonal structures, and this application does not limit this.

[0058] In addition, the positioning surface (such as positioning surface 111a or positioning surface 111b) can be a plane, a curved surface, or a bent surface, etc.

[0059] Alternatively, in other embodiments, prism 11 may also be a non-prismatic structure. For example, prism 11 may be a polyhedral structure such as a hexahedron. Alternatively, prism 11 may also be an irregular three-dimensional shape.

[0060] It is understood that in the prism assembly 10 provided in this application, since the prism 11 and the mounting bracket 13 can be fixedly connected by a fixing piece, the connection strength between the prism 11 and the mounting bracket 13 can be effectively improved. Furthermore, it also enhances the flexibility of the prism 11's structural design. For example, when the prism 11 has an irregular shape, the shape of the fixing piece can be adapted to ensure the connection effect between the prism 11 and the mounting bracket 13.

[0061] In practical applications, the shape of the fixing plate can be varied. For example, such as... Figure 3 and Figure 4 As shown, taking the fixing plate 12a as an example, in one embodiment provided in this application, the fixing plate 12a can be a flat plate structure. Specifically, one surface of the fixing plate 12a has a first fixing surface 121a, and the other surface has a second fixing surface 122a.

[0062] Please refer to the following: Figure 3 and Figure 4 In one embodiment provided in this application, the positioning surface 111a is a plane, and the first fixing surface 121a of the fixing piece 12a is also a plane. Therefore, when the first fixing surface 121a of the fixing piece 12a is a plane, it can be better fixedly connected to the positioning surface 111a to ensure the connection strength between the positioning surface 111a and the first fixing surface 121a of the fixing piece 12a. Correspondingly, when the second fixing surface 122a of the fixing piece 12a is a plane, it can be better fixedly connected to the mounting surface 13a to ensure the connection strength between the mounting surface 13a and the second fixing surface 122a of the fixing piece 12a.

[0063] It is understood that in other embodiments, when the positioning surface 111a is a curved or bent surface, the first fixing surface 121a of the fixing piece 12a can also be a curved or bent surface. Correspondingly, when the mounting surface 13a is a curved or bent surface, the second fixing surface 122a of the fixing piece 12a can also be a curved or bent surface.

[0064] In other words, in practical applications, the fixing piece 12a can be a flat plate structure or a bent or flexed plate structure. Alternatively, the fixing piece 12a can also be other shapes. This application does not limit the shape of the fixing piece 12a, the first fixing surface 121a and the second fixing surface 122a of the fixing piece 12a.

[0065] Furthermore, the method of achieving a fixed connection between the prism 11 and the fixing plate can be varied. For example, such as... Figure 5 and Figure 6 As shown. The prism 11 can be fixedly connected to the fixing plates 12a and 12b by adhesive bonding.

[0066] Specifically, a first adhesive layer 14a can be provided between the positioning surface 111a and the first fixing surface 121a of the fixing piece 12a, thereby achieving a fixed connection between the positioning surface 111a and the first fixing surface 121a. Similarly, a first adhesive layer 14b can be provided between the positioning surface 111b and the first fixing surface 121b of the fixing piece 12b, thereby achieving a fixed connection between the positioning surface 111b and the first fixing surface 121b of the fixing piece 12b.

[0067] In addition, such as Figure 6 As shown, in one embodiment provided in this application, the first fixing surface 121a of the fixing piece 12a may have a first adhesive filling groove 1211a. At least a portion of the first adhesive layer 14a can be filled into the first adhesive filling groove 1211a, thereby effectively increasing the bonding area between the first fixing surface 121a and the first adhesive layer 14a of the fixing piece 12a, thus improving the connection strength between the first fixing surface 121a and the first adhesive layer 14a of the fixing piece 12a and preventing delamination and other defects. The first fixing surface 121b of the fixing piece 12a may also have a first adhesive filling groove 1211b. At least a portion of the first adhesive layer 14b can be filled into the first adhesive filling groove 1211b, thereby effectively increasing the bonding area between the first fixing surface 121b and the first adhesive layer 14b of the fixing piece 12a, thus improving the connection strength between the first fixing surface 121b and the first adhesive layer 14b of the fixing piece 12a and preventing delamination and other defects.

[0068] Please see Figure 5 and Figure 6 In specific implementations, the structures of the first adhesive filling groove 1211a and the first adhesive filling groove 1211b can be varied. For example, taking the first adhesive filling groove 1211a as an example, in the length direction of the first adhesive filling groove 1211a, the first adhesive filling groove 1211a can be a straight line, a curve, a broken line, or other structures. In the length direction perpendicular to the first adhesive filling groove 1211a, the first adhesive filling groove 1211a can be a rectangular, semi-circular, or triangular structure, etc. This application does not limit the specific structure of the first adhesive filling groove 1211a.

[0069] Furthermore, the number of first adhesive filling grooves 1211a can be one, two, or more. This application does not limit the shape, number, or specific arrangement of the first adhesive filling grooves 1211a.

[0070] It is understandable that, in specific settings, the first glue filling tank 1211b can be set up in a similar manner to the first glue filling tank 1211a described above, and will not be elaborated here.

[0071] Of course, the prism 11 can also be fixedly connected to the fixing plates 12a and 12b in other ways. For example, taking fixing plate 12a as an example, fixing plate 12a can be made of materials such as nylon or polyimide. The fixing plate 12a and the prism 11 can also be fixedly connected using an in-mold injection molding process.

[0072] Of course, in other embodiments, the fixing plate 12a and the prism 11 can also be fixedly connected by other connection methods. This application does not limit the connection method between the fixing plate 12a and the prism 11.

[0073] In addition, the fixing plate 12a can also be made of materials such as aluminum, aluminum alloy, and stainless steel. This application does not limit the material of the fixing plate 12a.

[0074] It is understandable that the material and shape of the fixing plate 12b, as well as the connection method between the fixing plate 12b and the prism 11, can be similarly set with reference to the fixing plate 12a, and will not be elaborated here.

[0075] Furthermore, the mounting bracket 13a can be fixedly connected to the fixing pieces 12a and 12b in various ways. For example, the mounting bracket 13a can be fixedly connected to the fixing pieces 12a and 12b by adhesive bonding.

[0076] Specifically, a second adhesive layer 15a can be provided between the mounting surface 13a and the second fixing surface 122a of the fixing piece 12a, thereby achieving a fixed connection between the mounting surface 13a and the second fixing surface 122a of the fixing piece 12a. Similarly, a second adhesive layer 15b can be provided between the mounting surface 13b and the second fixing surface 122b of the fixing piece 12b, thereby achieving a fixed connection between the mounting surface 13b and the second fixing surface 122b of the fixing piece 12b.

[0077] In addition, such as Figure 5 and Figure 6As shown, in one embodiment provided in this application, the second fixing surface 122a of the fixing piece 12a has a second adhesive filling groove 1221a, and at least a portion of the second adhesive layer 15a is filled in the second adhesive filling groove 1221a. This effectively increases the bonding area between the second fixing surface 122a of the fixing piece 12a and the second adhesive layer 15a, thereby improving the connection strength between the second fixing surface 122a of the fixing piece 12a and the second adhesive layer 15a and preventing delamination and other defects. The second fixing surface 122b of the fixing piece 12b has a second adhesive filling groove 1221b, and at least a portion of the second adhesive layer 15b is filled in the second adhesive filling groove 1221b. This effectively increases the bonding area between the second fixing surface 122b of the fixing piece 12b and the second adhesive layer 15b, thereby improving the connection strength between the second fixing surface 122b of the fixing piece 12b and the second adhesive layer 15b and preventing delamination and other defects.

[0078] In specific implementations, the structures of the second adhesive filling groove 1221a and the second adhesive filling groove 1221b can be varied. For example, taking the second adhesive filling groove 1221a as an example, in the length direction of the second adhesive filling groove 1221a, the second adhesive filling groove 1221a can be a straight line, a curve, a broken line, or other structures. In the length direction perpendicular to the second adhesive filling groove 1221a, the second adhesive filling groove 1221a can be a rectangular, semi-circular, or triangular structure, etc. This application does not limit the specific structure of the second adhesive filling groove 1221a.

[0079] The number of second adhesive filling grooves 1221a can be one, two, or more. This application does not limit the shape, number, or specific arrangement of the second adhesive filling grooves 1221a.

[0080] It is understandable that, in specific settings, the second glue filling tank 1221b can be set up in a similar manner to the second glue filling tank 1221a described above, and will not be elaborated here.

[0081] In addition, in specific implementations, the mounting surface 13a may have a third adhesive filling groove 131a. At least a portion of the second adhesive layer 15a can be filled into the third adhesive filling groove 131a, thereby effectively increasing the bonding area between the mounting surface 13a and the second adhesive layer 15a, thus improving the connection strength between the mounting surface 13a and the second adhesive layer 15a and preventing defects such as delamination. The mounting surface 13b may have a third adhesive filling groove 131b. At least a portion of the second adhesive layer 15b can be filled into the third adhesive filling groove 131b, thereby effectively increasing the bonding area between the mounting surface 13b and the second adhesive layer 15b, thus improving the connection strength between the mounting surface 13b and the second adhesive layer 15b and preventing defects such as delamination.

[0082] In specific implementations, the structures of the third adhesive filling groove 131a and the third adhesive filling groove 131b can be varied. For example, taking the third adhesive filling groove 131a as an example, along its length, it can be a straight line, a curve, a broken line, or a similar structure. Along its length perpendicular to its length, it can be a rectangle, a semicircle, or a triangle. This application does not limit the specific structure of the third adhesive filling groove 131a.

[0083] Furthermore, the number of third adhesive filling grooves 131a can be one, two, or more. This application does not limit the shape, number, or specific arrangement of the third adhesive filling grooves 131a.

[0084] It is understandable that, in specific settings, the third glue filling tank 131b can be set up in a similar manner to the third glue filling tank 131a described above, and will not be elaborated here.

[0085] In addition, such as Figure 7 and Figure 8 As shown, in another embodiment provided in this application, a positioning protrusion 1222a can also be provided on the second fixing surface 122a of the fixing piece 12a. The mounting surface 13a can correspondingly have a positioning groove 132a, and the positioning protrusion 1222a can be located within the positioning groove 132a. Furthermore, a positioning protrusion 1222b can also be provided on the second fixing surface 122b of the fixing piece 12a. The mounting surface 13b can have a positioning groove 132b, and the positioning protrusion 1222b can be located within the positioning groove 132b.

[0086] When assembling the fixing plate 12a, fixing plate 12b, and mounting bracket 13, the relative position between the fixing plate 12a and the mounting bracket 13 can be ensured by the cooperation of the positioning protrusion 1222a and the positioning groove 132a. This effectively improves the assembly accuracy between the fixing plate 12a and the mounting bracket 13 and also facilitates installation. Similarly, the relative position between the fixing plate 12b and the mounting bracket 13 can be ensured by the cooperation of the positioning protrusion 1222b and the positioning groove 132b. This effectively improves the assembly accuracy between the fixing plate 12b and the mounting bracket 13 and also facilitates installation.

[0087] Of course, in specific applications, at least a portion of the second adhesive layer 15a can also be filled into the positioning groove 132a, thereby achieving a fixed connection between the fixing piece 12a and the mounting bracket 13. Correspondingly, at least a portion of the second adhesive layer 15b can also be filled into the positioning groove 132b, thereby achieving a fixed connection between the fixing piece 12b and the mounting bracket 13.

[0088] Alternatively, it can be understood that the positioning groove 132a can also serve the function of the second filling groove 1221a. In practical applications, the second filling groove 1221a can be omitted. Alternatively, the positioning groove 132 and the second filling groove 1221a can be provided simultaneously. Alternatively, the second filling groove 1221a can replace the positioning groove 132a, and the relative position between the fixing piece 12a and the mounting bracket 13 is ensured by the cooperation between the positioning protrusion 1222a and the second filling groove 1221a. Correspondingly, the positioning groove 132b can also serve the function of the second filling groove 1221b. In practical applications, the second filling groove 1221b can be omitted. Alternatively, the positioning groove 132 and the second filling groove 1221b can be provided simultaneously. Alternatively, the second filling groove 1221b can replace the positioning groove 132b, and the relative position between the fixing piece 12b and the mounting bracket 13 is ensured by the cooperation between the positioning protrusion 1222b and the second filling groove 1221b.

[0089] In practical applications, the structures of positioning grooves 132a and 132b can be varied. For example, taking positioning groove 132a as an example, along its length, positioning groove 132a can be a straight line, a curve, a broken line, or other similar structure. Along its length perpendicular to the length of positioning groove 132a, positioning groove 132a can be a rectangular, semi-circular, or triangular structure. This application does not limit the specific structure of positioning groove 132a.

[0090] The number of positioning grooves 132a can be one, two, or more. Similarly, the number of positioning protrusions 1222a can be one, two, or more.

[0091] In practical implementation, the number of positioning protrusions 1222a and the number of positioning grooves 132a can be the same. Alternatively, it can be understood that the positioning protrusions 1222a and the positioning grooves 132a correspond one-to-one. Alternatively, the number of positioning protrusions 1222a can be greater than the number of positioning grooves 132a. Alternatively, it can be understood that one positioning groove 132a can simultaneously mate with at least two positioning protrusions 1222a.

[0092] Of course, in other embodiments, one end of the positioning groove 132a may extend to the edge of the mounting surface 13a. When assembling the fixing piece 12a and the mounting bracket 13, the positioning protrusion 1222a can slide into the positioning groove 132a from one end, thereby effectively reducing the assembly difficulty.

[0093] Alternatively, in other embodiments, the positioning protrusion 1222a can also be an elastic structure, and a recess 1321a can be provided in the positioning groove 132a. When the positioning protrusion 1222a and the recess 1321a are elastically engaged, the relative fixation between the fixing piece 12a and the mounting bracket 13 can be achieved.

[0094] In some cases, the second adhesive layer 15a can be omitted. The fixed connection between the fixing piece 12a and the mounting bracket 13a can also be achieved by relying on the elastic snap-fit ​​between the positioning protrusion 1222a and the recess 1321a, thereby achieving the effect of no glue required, which is conducive to reducing assembly steps and improving assembly efficiency.

[0095] Of course, in some embodiments, the structures of the positioning protrusion 1222a and the positioning groove 132a can be interchanged. For example, the positioning protrusion 1222a on the second fixing surface 122a of the fixing piece 12a can be replaced with the positioning groove 132a, and the positioning groove 132a on the mounting surface 13a can be replaced with the positioning protrusion 1222a, which can also achieve the function of fixing the fixing piece 12a and the mounting bracket 13a. This application does not limit this.

[0096] It is understandable that when setting the positioning groove 132b and the positioning protrusion 1222b, a similar setting can be made with reference to the positioning groove 132a and the positioning protrusion 1222a described above, which will not be elaborated here.

[0097] In addition, such as Figure 7 and Figure 8 As shown, in one embodiment, the mounting bracket 13 can also be provided with a glue-blocking structure 16. The glue-blocking structure 16 can be located within the projection area of ​​the light-processing surface 112c to prevent the second adhesive layer 15a and the second adhesive layer 15b from overflowing onto the light-processing surface 112c. Additionally, the glue-blocking structure 16 can also prevent moving parts (such as the stator and mover in an optical image stabilization assembly) from sticking together. Furthermore, with the glue-blocking structure 16 provided, the amount of glue applied in a single application can be increased, avoiding the need for secondary glue application. For example, without the glue-blocking structure 16, to prevent glue overflow, the amount of glue applied in a single application is minimized, and secondary application is performed after the glue has solidified. However, with the glue-blocking structure 16 provided, the amount of glue applied in a single application does not need to be limited, making the manufacturing and installation process more convenient.

[0098] In practical applications, the adhesive-blocking structure 16 can be of various types. For example, the adhesive-blocking structure 16 can be an elongated protrusion. In specific implementations, the height of the protrusion can be greater than or equal to 300 μm, and the width of the protrusion can be greater than or equal to 500 μm. Alternatively, the adhesive-blocking structure 16 can also be an elongated groove. In specific implementations, the depth of the groove can be greater than or equal to 300 μm, and the width of the groove can be greater than or equal to 500 μm. This application does not limit the specific shape and size of the adhesive-blocking structure 16.

[0099] In addition, in specific applications, the prism assembly 10 can be directly used in various smart electronic devices with cameras or lenses, or the prism assembly 10 can be combined with optical image stabilization components in various smart electronic devices with cameras or lenses. This application does not make any specific limitations in this regard.

[0100] like Figure 9 and Figure 10 As shown in the illustration, this application embodiment also provides an optical image stabilization component 20, including a stator 21 and a mover 22. The mover 22 is movably mounted on the stator 21, and a mounting bracket 13 can be fixedly connected to the mover 22. Alternatively, it can be understood that the mounting bracket 13 can be a structural component independent of the mover 22. Or, it can be an integral part of the mover 22. The prism 11 can be fixed to the mounting bracket 13 by fixing plates 12a and 12b.

[0101] In this way, when the mover 22 moves relative to the stator 21, the prism 11 can be driven to move by the mounting bracket 13. Therefore, the direction of light propagation in the electronic device can be changed to achieve the effect of optical image stabilization.

[0102] In practical implementation, the stator 21 and the mover 22 can adopt commonly used structural types, which will not be elaborated here. In addition, in practical applications, the mover 22 can rotate relative to the stator 21 about the X-axis or Y-axis, or the mover 22 can translate relative to the stator 21. This application does not restrict the degree of freedom of the mover 22.

[0103] In addition, such as Figure 10 As shown, in another embodiment provided in this application, the optical image stabilization component may further include a protective protrusion 23, which can be fixed to the surface of the mounting bracket 13. When the optical image stabilization component 20 is being transported or assembled, the protective protrusion 23 can effectively protect the prism 11 or other components in the optical image stabilization component 20, thereby improving the safety of the optical image stabilization component 20.

[0104] In a specific configuration, the optical image stabilization assembly 20 may also include a protective housing 24. The protective housing 24 may be placed around the outer periphery of the stator 21 and the mover 22, thereby providing effective protection for the stator 21 and the mover 22.

[0105] The protective shell 24 can be made of conductive materials such as aluminum or aluminum alloy, which can provide effective protection for the stator 21 and the mover 22, and also provide effective electromagnetic shielding.

[0106] Additionally, the protective protrusion 23 can be positioned within the movement gap between the mounting bracket 13 and the protective housing 24 to prevent hard collisions between them. For example, during the handling of the optical image stabilization assembly 20, relative movement may occur between the protective housing 24 and the mounting bracket 13; the protective protrusion 23 can effectively prevent hard collisions between them. Alternatively, the protective protrusion 23 can effectively limit the range of motion of the mounting bracket 13 (or the mover 22) to prevent damage to the optical image stabilization assembly 20.

[0107] The protective protrusion 23 can be made of materials such as foam or rubber, which have a cushioning effect. Additionally, the protective protrusion 23 can also be located on the outer surface of the stator 21 or on the surface of other components. In specific applications, the number, location, and size of the protective protrusion 23 can be adjusted adaptively according to the actual situation; this application does not impose any limitations on this.

[0108] In addition, such as Figure 11 As shown, this application also provides a camera 30, including a housing 31, a lens 101, an image sensor 102, and an optical image stabilization assembly 20. The prism (not shown), lens 101, and image sensor 102 are sequentially arranged within the housing 31 along the light propagation path. When light or objects enter the prism, the direction of light propagation is changed, allowing it to enter the lens 101. The lens 101 performs optical processing on the light or objects, which is then transmitted to the image sensor 102. The image sensor 102 converts the light signal from the light or objects into an electrical signal.

[0109] In practical applications, the camera 30 can be used in various types of electronic devices. Taking a smartphone as an example, the processor in the smartphone can communicate with the stator or mover in the camera 30 to control the attitude of the mover. In practical applications, when a user holds a smartphone to take a photo or record a video, their hand may shake. During this process, the processor can control the mover to make movements so that the image sensor can obtain stable image information, thereby achieving the effect of image stabilization.

[0110] Of course, in practical applications, the prism assembly 10 can also be directly installed in the electronic device to change the propagation path of light. Alternatively, the optical image stabilization assembly 20 can also be directly installed in the electronic device to achieve the function of optical image stabilization.

[0111] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
