detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Please refer to FIG. 1. Each embodiment of the present application provides a camera module 11 and an electronic device 10 using the camera module 11 to solve the problem of low assembly efficiency of general camera modules and the use of these camera modules. The problem of poor experience of electronic equipment. The camera module 11 provided in the present application can be embedded in the housing 12 of the electronic device 10 and used to capture images, and the captured images can be displayed on the electronic device 10 after processing. In order to improve the shooting effect and achieve richer shooting functions, the camera module 11 may include multiple cameras; that is, the number of cameras is greater than or equal to two, for example, the number of cameras may be two, three, four, or Five waits. The multiple cameras may include ultra-wide-angle cameras, wide-angle cameras, TOF cameras, structured light cameras, or zoomable cameras according to usage requirements. It should be understood that the camera module 11 may also include components such as a flashlight and an infrared lamp. The camera module 11 shown in FIG. 1 is located on the back side of the electronic device 10, and serves as the rear camera module 11; however, in some other embodiments, the camera module 11 provided in each embodiment of the present application It can also be located on the front side of the electronic device 10 as the front camera module 11. The electronic device 10 can be, for example, a mobile phone, a tablet computer, a notebook computer, a desktop computer, or a smart TV that can be equipped with a camera module 11, and there is no restriction on this.

According to different camera types and specifications, the size of each camera is also large or small, and multiple cameras of different sizes are arranged on the electronic device 10. It should be understood that, as shown in FIGS. 2 and 3, the size of the camera (for example, a1, a2) refers to the lens size (or lens diameter) of the camera. Since the camera in the camera module 11 needs to capture images of the outside world; on the other hand, the user can also observe the camera module 11 from the outside world and see the lens of each camera. Please refer to FIGS. 2 and 3 at the same time. In some embodiments, in order to fix the cameras or reduce the possibility of the cameras being damaged, the camera module 11 may also include a decorative sheet assembly 100, which includes but is not limited to ：The decorative sheet main body 110 and the cover plate 130 are stacked. The decorative sheet main body 110 is provided with camera holes corresponding to the number of cameras, and the camera holes are used for the corresponding cameras to pass through, so as to protect the cameras.

In some embodiments, taking the camera module 11 as the rear camera module of the electronic device 10 as an example for understanding, due to the high integration of the electronic device 10, considering that the camera module 11 occupies the housing 11 of the electronic device 10 In the internal space, part of the camera lens can be exposed outside the housing 12, and the part of the camera lens exposed outside the housing 11 can be protected by the cooperation of the decorative sheet assembly 100 and the housing 12, so as to reduce the camera mold. The group 11 occupies the internal space of the housing 11.

Normally, there will be a certain gap between the camera and the hole wall of the decorative sheet main body 110 (for example, the size b1 is greater than a1, and the size b2 is greater than the size a2) to adapt to the process error of the camera. The cover plate 130 is provided with a silk-screen ring corresponding to the camera/camera hole, and a part of the cover plate 130 in the silk-screen ring allows light to pass through, so that the corresponding camera captures an image of the outside world. The area outside the silk screen circle is set to be opaque, so that the gap between the camera and the hole wall of the decorative sheet main body 110 can be blocked, and a part of the decorative sheet main body 110 can be blocked.

The number of silk-screened circles on a general cover plate corresponds to the number of cameras, and the size of the silk-screened circles corresponds to the size of the camera. That is, if the size of the camera is large, the size of the corresponding silk-screen ring is also large; if the size of the camera is small, the size of the corresponding silk-screen ring is also small. When assembling a general camera module, due to the difference in the size of each silk screen ring on the cover, it is necessary to pay special attention to the placement direction of the cover during assembly to complete the assembly of the camera module. To a certain extent, the assembly efficiency of the camera module is affected; and the assembled electronic device due to the size difference of each silk-screen ring makes the actual experience of the user poor.

In the camera module 11 provided by the present application, in order to improve the assembly efficiency of the camera module 11 and improve the user experience effect, the decorative sheet assembly 100 of the present application further includes: a shielding member 120; the shielding member 120 can shield a small size The area around the camera (ie, small camera) within a certain range; for example, the blocking member 120 can block the gap between the small camera and the hole wall of the camera hole (corresponding to the small camera), and block part of the decorative sheet main body 110. Based on the shielding effect of the shield 120, when designing the cover 130, the size of the silk-screen ring on the cover 130 (for example: d1, d2) can be set to the same size, and the size of the silk-screen ring can be basically the same as the size of the large camera Or the size of the silk screen ring may be slightly smaller than the size of the large camera in the camera module 11, so that the cover 130 can cover the periphery of the large camera. Therefore, when assembling the camera module 11, the staff does not need to pay special attention to the placement direction of the cover plate 130, and the assembly efficiency of the camera module 11 can be improved. Since the assembled electronic device 10 has the same size of the silk screen rings, the actual experience effect of the user can also be improved, so as to improve the competitiveness of the electronic device 10.

It should be understood that in each embodiment, in addition to the camera module 11, the electronic device 10 may also include a display module, a fingerprint recognition module, an antenna module, a storage module, or a battery module to realize the electronic device 10 Various functions.

It should be understood that although four camera holes are shown in some figures of the present application (for example: FIG. 4), in order to facilitate the understanding of the technical solution of the present application, two cameras and one shielding member 120 are used as examples in each embodiment. To illustrate, but not to limit the number and position settings of the camera and the shield 120 and other components, and the four camera holes shown in the figure can also be used to accommodate flash or infrared light and other auxiliary shooting structures. The limit is only used to accommodate the camera.

In some other embodiments, the number of cameras may be three, and the number of shielding members 120 may be one or two. When the number of the blocking member 120 is one, one of the three cameras has a smaller size camera. When the number of the blocking member 120 is two, there are two smaller cameras among the three cameras. The two smaller-sized cameras can be divided into a relatively larger camera and a relatively smaller camera, or the two smaller-sized cameras are the same or similar in size. When the two smaller-sized cameras include a relatively large camera and a relatively small camera, correspondingly, the camera module 11 includes two shielding members 120 of different sizes to compare the two sizes respectively. The area within a certain range around the small camera is blocked.

2 and 3 again, in some embodiments, the camera module 11 includes a first camera 201 and a second camera 202, and the size a1 of the first camera 201 is larger than the size a2 of the second camera 202. In some embodiments of the present application, the first camera 201 may be referred to as a large camera, and the second camera 202 may be referred to as a small camera. It should be understood that the types and specifications of the large camera and the small camera may be different according to requirements, and there is no limitation.

Please refer to FIGS. 4 and 5 at the same time. The decorative sheet assembly 100 includes a decorative sheet main body 110, a shield 120 and a cover 130. The decorative sheet main body 110 has a first camera hole 111 and a second camera hole 112 opposite to each other. The first camera hole 111 and the second camera hole 112 can be used for the first camera 201 and the second camera 202 to extend in to reduce the entire camera. The thickness of the module 11. For example, the first camera hole 111 can accommodate part of the lens of the first camera 201, and the second camera hole 112 can accommodate part of the lens of the second camera 202. In this way, while reducing the thickness of the camera module 11, the first camera 201 and the second camera 202 can be protected from being damaged or broken by bumps.

Corresponding to the sizes of the first camera 201 and the second camera 202, the size b1 of the first camera hole 111 is correspondingly larger (or slightly larger than) the size b2 of the second camera hole 112. Based on this, the second camera hole 112 is provided with a shield 120 coaxial with the second camera hole 112, and the shield 120 has a first through hole 122. The size c2 of the first through hole 122 is smaller than the size b2 of the second camera hole 112; or, the size c2 of the first through hole 122 is smaller (or slightly smaller than) the size b2 of the second camera. Therefore, after the blocking member 120 is set, it can block the gap between the second camera 202 and the hole wall of the second camera hole 112; or it can also block a part of the second camera 202 (that is, block the second camera 202). The periphery) to improve the user experience.

In some embodiments, the shield 120 may be in the shape of a circular ring or a circular ring-like shape, and has an inner ring and an outer ring opposite to each other. As shown in FIG. 6, the shielding member 120 is in the shape of a circular ring. It should be understood that the area enclosed by the inner ring is the area of the first through hole 122, which can allow light to pass through so that the second camera 202 can capture images. The area between the outer ring and the inner ring is the occluded area, and it can also be called the ring part. When the first through hole 122 and the second camera hole 112 are coaxial, the ring part can be used to protect the surrounding area of the small camera. The area is occluded. For example, the blocking member 120 may block the gap between the second camera 202 and the hole wall of the decorative sheet main body 110; or, the blocking member 120 may also jointly block a certain area of the decorative sheet main body 110 close to the second camera hole 112.

In some embodiments, the cover 130 is provided with a silk-screened circle at a position corresponding to the camera, and the number of the silk-screened circle corresponds to the number of the camera. The areas within the silk-screened circles can be set as light-transmitting areas for the corresponding camera to capture images of the outside world, and the areas outside the silk-screened circles can be light-shielding areas to block part of the internal structure of the camera module 11. It should be understood that in some other embodiments, the area outside the silk screen ring may also be set as a light-transmitting area, and a part of the main body 110 of the decorative sheet is exposed, without limitation.

As shown in the cover 130 shown in FIG. 7, the cover 130 exemplarily marks the first silk-screened circle 131 and the second silk-screened circle 132. Corresponding to the above-exemplified example, in some embodiments, the size of the first silk-screened ring 131 and the second silk-screened ring 132 are the same (that is, the size d1 is equal to the size d2). The first silk-screened circle 131 can be used for the first camera 201 to capture images of the outside world, and the second silk-screened circle 132 can be used for the second camera 202 to capture images of the outside world.

8 and 9 at the same time, the size a1 of the first camera 201 may be approximately the same as the size d1 of the first silk-screen ring 131, or the lens size a1 of the first camera 201 may be slightly larger than the size d1 of the first silk-screen ring 131. As a result, the first silk screen ring 131 shields the periphery of the first camera 201 while ensuring that the first camera 201 captures an image of the outside world. However, due to the blocking effect of the blocking member 120 on the gap between the second camera 202 and the decorative sheet main body 110, even if the first silk-screened ring 131 and the second silk-screened ring 132 are set to the same size (the size d1 is equal to the size d2), the larger The large second silk screen ring 132 will not expose the gap between the second camera 202 and the main body 110 of the decorative sheet. In this way, the shielding member 120 can improve the user's experience of the electronic device 10 loaded with the camera module 11.

It should be understood that since the size of the first silk-screen ring 131 and the second silk-screen ring 132 are the same, when assembling the camera module 11, there is no need to pay special attention to the placement direction of the cover plate 130, so as to improve the assembly efficiency of the camera module 11. . Correspondingly, the first silk-screened circles 131 and the second silk-screened circles 132 are symmetrically distributed with respect to the cover plate 130. For example, the cover 130 is rectangular and includes a symmetrical first area and a second area. The first silk-screened circle 131 is located at the center of the first area, and the second silk-screened circle 132 is located at the center of the second area.

In some embodiments, the cover 130 may be substantially rectangular and have four silk-screened circles. The four silk screen rings have the same size and are distributed on the cover plate 130 in an array. For example, the four silk screen circles can be distributed in an array on the four corners of the rectangular cover 130. In some other embodiments, the cover plate 130 has a circular shape, and the four silk screen rings are symmetrically distributed on both sides of a diameter of the circular cover plate 130. For example, the four silk-screened circles may be in an “X” shape and distributed on the circular cover 130; and the intersection of the “X” shape coincides with the center of the circular cover 130.

Referring to FIGS. 5 and 9, in some embodiments, in order to reduce the thickness of the decorative sheet assembly 100 (after increasing the shielding member 120), the decorative sheet main body 110 may further be provided with a recess 115 which surrounds the second The camera hole 112 can be used to place the shielding member 120 around the camera hole 112. It should be understood that the recessed direction of the recess 115 is a direction toward the interior of the decorative sheet main body 110. By placing the shielding member 120 on the recess 115 of the decorative sheet main body 110, the difficulty of positioning when assembling the shielding member 120 can also be reduced, so as to improve the assembly efficiency.

In some embodiments, the shape of the recess 115 may correspond to the shape of the shield 120. The shape of the shield 120 is a circular ring, and the shape of the recess 115 is also a circular ring. In other embodiments, the shape of the recess 115 may not correspond to the shape of the shield 120, as long as the recess 115 can be provided for the shield 120. For example, the shape of the shielding member 120 is a circular ring, and the shape of the recess 115 is a rectangle circumscribing the circular ring. The rectangular recess 115 can also be provided with a circular shielding member 120.

In some embodiments, as illustrated in FIG. 9, the first adhesive 140 may be used to achieve the fixation between the shield 120 and the decorative sheet main body 110. Taking the decorative sheet main body 110 provided with the recessed platform 115 as an example for description, the first adhesive 140 can be placed on the recessed platform 115 first, and then the shield 120 and the first adhesive 140 on the recessed platform 115 can be bonded. Alternatively, the first adhesive 140 and the shield 120 may be bonded first, and then the shield 120 is placed on the recess 115. It should be understood that the bonding sequence of the first adhesive 140 and the shield 120/recess 115 can be adjusted according to requirements, and the different bonding methods illustrated above can all achieve the fixation between the shield 120 and the decorative sheet main body 110. .

It should be understood that the shielding member 120 and the decorative sheet main body 110 in each embodiment can be fixed by the first adhesive 140. However, this does not limit that the shield 120 and the decorative sheet main body 110 in each embodiment can be fixed in other ways. Please refer to FIG. 10 and FIG. 11 at the same time. In some embodiments, the shielding member 120 includes an annular portion 120a and a protruding portion 120b. The annular portion 120a and the protruding portion 120b may be integrally formed, or two parts may be combined together to form the shield 120. Corresponding to the protruding portion 120b of the shield 120, the decorative sheet main body 110 is provided with a mounting portion 116 in the region of the recess 115. As shown in FIGS. 12 and 13, the mounting portion 116 can be embedded with the protruding portion 120 b of the shield 120, so as to achieve the fixation between the shield 120 and the main body 110 of the decorative sheet.

In some embodiments, as illustrated in FIG. 11, in one shield 120, the number of protrusions 120b may be one, and the protrusion 120b cooperates with the mounting portion 116 on the decorative sheet main body 110 to realize the shield 120 and Fixing between the main body 110 of the decorative sheet. In some other embodiments, a plurality of protrusions 120 b may be provided in one shield 120, and the plurality of protrusions 120 b are spaced apart from the outer periphery of the annular portion 120 a of the shield 120. The decorative sheet main body 110 is provided with a plurality of mounting portions 116 at positions corresponding to the plurality of protrusions 120b. Thus, through the cooperation between the plurality of protrusions 120b and the plurality of mounting portions 116, the possibility of the protrusions 120b sliding out from the mounting portion 116 can be reduced, so as to improve the stability of the connection between the shield 120 and the decorative sheet main body 110 . As shown in FIG. 14, the shield 120 is provided with an annular portion 120a and two protrusions 120b, and the two protrusions 120b are arranged at intervals.

The area of the imaging hole 112. The protrusion 120b of the shielding member 120 can fix the shielding member 120 and the main body 110 of the decorative sheet.

In order to ensure the shielding effect, the shielding member 120 may be designed as a sheet structure. As shown in FIG. 6, in some embodiments, when the shield 120 only includes the annular portion 120a, the annular portion 120a has a sheet structure. As shown in FIG. 11 or FIG. 14, when the shield 120 includes a protrusion 120 b in addition to the annular portion 120 a, the protrusion 120 b may refer to a coplanar structure extending from the shield 120 toward the periphery of the annular portion 120 a. Correspondingly, the mounting portion 116 refers to a groove-like structure extending toward the periphery of the recess 115. Therefore, in addition to the above-mentioned shielding function, the sheet-shaped shielding member 120 can also reduce the thickness of the shielding member 120 and save the occupied space, so as to facilitate transportation.

Please refer to FIGS. 15 and 16 at the same time. In some other embodiments, the annular portion 120a is a sheet structure; the protrusion 120b is a columnar structure; the protrusion 120b is disposed on the annular portion 120a and is perpendicular to the annular portion 120a .

Compared with other embodiments, the shielding member 120 provided by this type of embodiment occupies a larger volume, but at the same time, it can also be easily grasped by a machine or manually. Based on the relationship that the protrusion 120b is located on the annular portion 120a and is perpendicular to the annular portion 120a, during installation, only the protrusion 120b of the columnar structure needs to be inserted into the mounting portion 116 of the hole-like structure to achieve fixation, which can simplify The assembling steps of the shield 120 and the decorative sheet main body 110 improve the assembly efficiency of the camera module 11.

It should be understood that the protrusion 120b of the columnar structure and the annular portion 120a of the sheet structure may be fixed by adhesive bonding or interference fit; in addition, the protrusion 120b and the annular portion 120a may also be manufactured during manufacture. In the process, it is integrally formed by means of molds, etc., and there is no restriction on this. Based on design considerations and considerations such as the stability of the connection between the shield 120 and the decorative sheet main body 110, correspondingly, the mounting portion 116 of the hole-shaped structure can penetrate the decorative sheet main body 110 (ie through holes) to reduce (due to the columnar structure) There may be a gap between the annular portion 120a and the recess 115 caused by the manufacturing process error. In addition, the mounting portion 116 of the hole-like structure may not penetrate the decorative sheet main body 110 (ie blind hole) to increase the contact area between the protruding portion 120b and the mounting portion 116 to ensure that the decorative sheet assembly 100 is resistant to falling and damage. And other aspects of performance.

It should be understood that the first adhesive 140, the protruding portion 120b, and the mounting portion 116 shown above cooperate with the two types of fixing methods, and one of them can be used, or they can be used at the same time. Compared with the first adhesive 140 alone or the fixing method in which the protrusion 120b and the mounting part 116 are used together, when the first adhesive 140 and the fixing method in which the protrusion 120b and the installation part 116 cooperate are used at the same time, the shield can be made The fixed relationship between 120 and the main body 110 of the decorative sheet is more stable, so as to reduce the risk of the shielding member 120 being separated from the recess 115.

Taking the camera module 11 shown in FIG. 9 as an example, in some embodiments, the fixing between the main body 110 of the decorative sheet and the cover 130 can be achieved by the second adhesive 150. Illustratively, the second adhesive 150 may be placed on the main body 110 of the decorative sheet first, and then the cover 130 and the second adhesive 150 may be bonded. Alternatively, the second adhesive 150 and the cover 130 may be bonded first, and then the cover 130 is placed on the main body 110 of the decorative sheet. That is, the bonding sequence of the second adhesive 150 and the cover plate 130/decorative sheet main body 110 can be adjusted according to requirements.
