Electronic devices are generally equipped with cameras for taking photos. From the appearance of the electronic device, a transparent window is designed in the area corresponding to the camera on the shell to facilitate camera imaging.

[0059] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] With the development of communication technology, electronic devices such as mobile phones, tablet computers, cameras, etc. have become indispensable tools in people's lives. These electronic devices are usually equipped with cameras to realize the photo taking function. From the appearance of the electronic device, a transparent window will be designed in the area corresponding to the camera on the shell to facilitate camera imaging, and the size of the transparent window directly affects the appearance of the electronic device. The smaller the size of the transparent window, the better the overall sense of the electronic device.

[0062] Take the rear camera package of a mobile phone as an example. Figure 1As shown, the rear camera packaging structure of the mobile phone in the related art includes a battery cover 11, a rear camera decorative part adhesive 12, a rear camera decorative part 13, a rear camera lens adhesive 14, a rear camera lens 15, a middle frame 16 and a rear camera sealing foam 17, and a camera transparent window is silk-screened on the rear camera lens 15. During assembly, the rear camera decorative part 13 is first mounted on the battery cover 11 using the rear camera decorative part adhesive 12, and then the rear camera lens 15 is assembled on the rear camera decorative part 13 using the rear camera lens adhesive 14, and then the rear camera 10 is mounted on the middle frame 16, and finally the rear camera decorative part 13 equipped with the rear camera lens 15 is mounted on the middle frame 16, and the rear camera decorative part 13 is used to position the rear camera 10, wherein a camera sealing foam 17 is provided between the rear camera 10 and the rear camera decorative part 13 to seal the rear camera 10.

[0063] In order to ensure the imaging effect of the camera, the size of the transparent window is usually required to be larger than the viewing angle of the rear camera 10. However, if the size of the transparent window is too large, it is easy to cause the body of the electronic device to be not tightly sealed in appearance, and the user may see the internal structure of the device, which brings a poor overall perception. In order to avoid this situation, the related art usually raises the rear camera 10 to make it as close to the rear camera lens 15 as possible, so that the size of the transparent window can be reduced to a certain extent. But at the same time, this design will also cause the rear camera 10 to protrude significantly relative to the battery cover 11, which is not conducive to the thinness of the body.

[0064] In order to reduce the thickness of the electronic device body in the camera packaging area, an embodiment of the present application provides a camera assembly structure, which can be applicable to devices such as mobile phones, tablets, notebooks, and can also be applied to devices such as cameras and camcorders.

[0065] like Figure 2 As shown, the camera assembly structure provided in the embodiment of the present application includes a camera module 2, a circuit board 3, a light-transmitting cover 4 and a light-transmitting protective screen 5.

[0066] In the embodiment of the present application, the lens holder 21 of the camera module 2 is connected to the circuit board 3; the light-transmitting cover 4 includes a soft light-transmitting plate 41 and a positioning member 42, the soft light-transmitting plate 41 is abutted against the lens 22 of the camera module 2, the positioning member 42 surrounds the camera module 2, one end of the positioning member 42 is connected to the soft light-transmitting plate 41, and the other end is abutted against the lens holder 21; the light-transmitting protective screen 5 is connected to the side of the soft light-transmitting plate 41 away from the lens 22.

[0067] The camera module 2 is a key component of the electronic device to realize the photo function and can collect images. The camera module 2 is usually electrically connected to the circuit board 3 to realize the circuit control logic. The camera module 2 may include a lens holder 21 and a lens 22. The lens holder 21 may be fixedly connected to the circuit board 3, and the lens 22 is located in the lens holder 21.

[0068] The light-transmitting cover 4 is a component used to position and protect the camera module 2, and is usually directly covered on the camera module 2. Among them, compared with the camera lens made of hard materials in the related art, the hardness of the soft light-transmitting plate 41 is less than the hardness of the lens 22 of the camera module 2, and will not scratch the lens 22. Therefore, the soft light-transmitting plate 41 can directly contact the lens 22, thereby realizing the zero-matching installation of the light-transmitting cover 4 and the camera module 2 in the Z direction (thickness direction) of the fuselage; and based on the light-transmitting characteristics of the soft light-transmitting plate 41, light can directly pass through the soft light-transmitting plate 41 and enter the lens 22. At this time, there is no need for the camera lens 22 to protrude excessively from the shell surface of the electronic device, which greatly reduces the thickness of the body of the electronic device in the camera packaging area. The material of the soft light-transmitting plate 41 can be determined according to actual needs, as long as it can ensure that its material will not scratch the camera module 2 and can meet the light transmittance requirements when taking pictures. The positioning member 42 surrounds the camera module 2, with one end of the positioning member 42 connected to the soft light-transmitting plate 41 and the inner wall of the other end abutting against the lens mount 21. This can limit the position of the camera module 2 on the one hand to ensure that there is no excessive positional displacement between the camera module 2 and the soft light-transmitting plate 41; on the other hand, it can also protect the camera module 2. Since the camera module 2 has a relatively high requirement for precision, it can also prevent other structures inside the fuselage from colliding with the camera module 2 and causing damage.

[0069] The light-transmitting protective screen 5 is a structure used to protect the light-transmitting cover 4. After the light-transmitting protective screen 5 is connected to the soft light-transmitting plate 41 on the outside of the soft light-transmitting plate 41, it can prevent external water and dust from entering the body of the electronic device on the one hand, and on the other hand, it can also prevent the soft light-transmitting plate 41 from being exposed to the outside and being worn or dirty, thereby affecting the light-transmitting effect. In the embodiment of the present application, when the camera module 2 is the front camera module of the electronic device, the light-transmitting protective screen 5 can be, for example, the front camera lens or the display screen of the electronic device; when the camera module 2 is the rear camera module of the electronic device, the light-transmitting protective screen 5 can be, for example, the rear camera lens or the display screen of the secondary screen of the electronic device. Among them, the secondary screen refers to the display screen other than the main display screen in a dual-screen or multi-screen electronic device, such as a side screen, a back screen, etc., and illustratively, the light-transmitting protective screen 5 of the rear camera module can be the back screen of the electronic device, and the back screen and the main display screen are respectively located on opposite sides of the body. In some embodiments, the back screen of the electronic device may include a lens area and a display area, and the screen in the lens area is used as the light-transmitting protective screen 5. Therefore, in the camera assembly structure provided by the embodiment of the present application, the light-transmitting cover 4 and the camera module 2 are installed in a zero-matching manner in the Z direction (thickness direction) of the electronic device, wherein the soft light-transmitting plate 41 of the light-transmitting cover 4 has a very low hardness and can directly contact the lens 22 of the camera module 2, ensuring that the viewing angle range of the lens 22 is not affected while also reducing the size of the transparent window, so that the lens 22 does not protrude excessively from the shell surface of the electronic device; the positioning member 42 of the light-transmitting cover 4 surrounds the camera module 2, ensuring that the positions of the lens 22 and the soft light-transmitting plate 41 are relatively fixed, and the naked eye cannot usually see the internal structure of the body through the soft light-transmitting plate from the outside. Therefore, the camera assembly structure provided by the embodiment of the present application has a compact structure and a small protrusion relative to the surface of the electronic device shell, which ensures the camera imaging effect while also facilitating the realization of a light and thin body of the electronic device.

[0070] In some implementations of the embodiments of the present application, the soft light-transmitting plate 41 is made of optical silicone. Optical silicone has high light transmittance, high elasticity and good resistance to ultraviolet aging. Therefore, in addition to ensuring the imaging effect of the camera, it can also protect the electronic device and improve the camera module 2. For example, when the electronic device falls, the optical silicone will not be broken due to its good resilience, which prevents the possibility of debris entering the camera and affecting the camera function. It can also resist external deformation, reduce the impact force on the camera module 2, and improve the service life of the camera module 2.

[0071] In some embodiments of the present application, the optical silicone can be directly injected onto the light-transmitting protective screen 5 by an in-mold injection molding process, thereby manufacturing a soft light-transmitting plate 41, so as to ensure good connection strength between the soft light-transmitting plate 41 and the light-transmitting protective screen 5. Of course, in other embodiments of the present application, other methods can also be used to connect the soft light-transmitting plate 41 and the light-transmitting protective screen 5, such as bonding.

[0072] Taking the front camera of a mobile phone as an example, during assembly, the front camera module is first connected to the circuit board 3 (usually the main board), an opening is opened on the middle frame of the mobile phone, and the front camera module is located in the opening; then the optical silicone is injection molded onto the light-transmitting protective screen 5 (usually the mobile phone screen) to form a light-transmitting cover 4, and finally glue is applied to the side of the light-transmitting protective screen 5 facing the middle frame of the mobile phone to make it adhere to the middle frame. At this time, the light-transmitting cover 4 enters the opening of the middle frame and covers the front camera module, thus completing the assembly of the entire camera module 2.

[0073] In some implementations of the present application, the connection strength between the soft light-transmitting plate 41 and the light-transmitting protective screen 5 can also be increased by a connection structure. Figure 3 As shown, the flexible light-transmitting plate 41 may have a first connection portion 411 , which is located on a side of the flexible light-transmitting plate 41 away from the lens 22 ; the light-transmitting protective screen 5 may have a second connection portion 51 , which is cooperatively connected to the first connection portion 411 .

[0074] The first connection portion 411 and the second connection portion 51 may have various structures. Figure 4-6 , two possible structures are described:

[0075] In the first possible structure, Figure 4 As shown, the first connection portion 411 includes a first protrusion 4111 and a second protrusion 4112, the first protrusion 4111 surrounds and is connected to the second protrusion 4112, and in a direction perpendicular to the flexible light-transmitting plate 41, the height of the second protrusion 4112 is greater than the height of the first protrusion 4111. The second connection portion 51 includes a limiting opening 511 and a recessed ring portion 512, and the recessed ring portion 512 surrounds the limiting opening 511. After installation, the first protrusion 4111 is located in the recessed ring portion 512, and the second protrusion 4112 is located in the limiting opening 511.

[0076] In this structure, due to the presence of the first protrusion 4111 and the second protrusion 4112, the contact area between the flexible light-transmitting plate 41 and the light-transmitting protective screen 5 is increased, and thus the connection strength between the flexible light-transmitting plate 41 and the light-transmitting protective screen 5 can be improved regardless of whether they are connected by in-mold injection molding or bonding. In addition, the first protrusion 4111 can be exposed from the limiting opening 511, and when the electronic device falls, the first protrusion 4111 can also play a certain role in mitigating the impact, thereby reducing the possibility of the light-transmitting protective screen 5 being broken.

[0077] In related technologies, such as Figure 1 As shown, the rear camera lens 15 and the rear camera 10 are both positioned by the rear camera decorative part 13. There is no direct positioning relationship between the two, the tolerance chain is long, and the eccentricity problem is prone to occur. However, in the embodiment of the present application, since the lens 22 is in contact with the soft light-transmitting plate 41, the center of the lens 22 completely coincides with the center of the light-emitting surface of the optical silicone, and the eccentricity problem does not occur. In order to further improve the accuracy and convenience of positioning, in some embodiments of the present application, the lens 22 of the camera module 2 can also be positioned with the help of the first protrusion 4111 and the second protrusion 4112. As shown in FIG. Figure 5 As shown, the orthographic projection of the axis of the lens 22 of the camera module 2 on the flexible light-transmitting plate 41 is located within the orthographic projection of the second protrusion 4112 on the flexible light-transmitting plate 41, so that the light can enter the lens 22 after passing through the second protrusion 4112. In a possible design, the axis of the lens 22 can also be arranged to coincide with the axis of the first protrusion 4111 and the second protrusion 4112, so that it can be ensured that all light passing through the second protrusion 4112 can enter the lens 22.

[0078] In the second possible structure, Figure 6 As shown, the first connection portion 411 is a third protrusion 4113 , the second connection portion 51 is a limiting groove 513 , and the third protrusion 4113 is located in the limiting groove 513 .

[0079] Compared with the first possible structure, the light-transmitting protective screen 5 in the second possible structure is not provided with a limiting opening 511, which effectively prevents the wear and dirt of the soft light-transmitting plate 41, ensures good light transmission, and prevents water and dust from entering through the limiting opening 511, thereby reducing the aging rate of the optical silicone and increasing the service life of the light-transmitting cover 4.

[0080] In some implementations of the embodiments of the present application, Figure 7 As shown, the positioning member 42 is cylindrical, and at least a portion of the lens holder 21 and the lens 22 are located in the inner space of the positioning member 42. The cylindrical positioning member 42 can better wrap the camera module 2 and has a better protection effect.

[0081] For example, Figure 8 As shown, the positioning member 42 may include an annular portion 421 and a plurality of protrusions 422; one end of the annular portion 421 is connected to the soft light-transmitting plate 41, and the other end is connected to the plurality of protrusions 422; the plurality of protrusions 422 are distributed along the circumference of the annular portion 421, and there is a gap 423 between any two adjacent protrusions 422; the lens 22 is located in the annular portion 421, the lens holder 21 is surrounded by the plurality of protrusions 422 and abuts against the inner wall of the protrusion 422, and a portion of the lens holder 21 is located in the gap 423 and abuts against the other end of the annular portion 421.

[0082] Among them, in one possible design, such as Fig. 9 As shown, the positioning member 42 can be made of a hard material, and there is a gap between the positioning member 42 and the lens 22. This is to prevent the hard annular portion 421 from squeezing the lens 22 and damaging the lens 22. Since the lens holder 21 abuts against the inner wall of the protruding portion 422, the lens holder 21 and the lens 22 are relatively stationary with the positioning member 42 inside the light-transmitting cover 4, and the annular portion 421 will not squeeze the lens 22. It should be noted that in the embodiment of the present application, the hard material refers to a material with a hardness greater than or equal to the hardness of the lens 22, and the soft material refers to a material with a hardness less than the hardness of the lens 22.

[0083] In another possible design, the positioning member 42 may be made of optical silicone material, and the soft light-transmitting plate 41 and the positioning member 42 may be an integrally formed structure. In this case, the annular portion 421 may be in contact with the lens 22 or may not be in contact with the lens 22.

[0084] In some implementations of the present application, the positioning member 42 is a light shielding member. The light transmittance of the light shielding member is usually poor, or even completely opaque. Setting the positioning member 42 as a light shielding member can prevent the light from being transmitted between adjacent cameras and affecting the imaging effect when the camera module 2 includes multiple lenses 22.

[0085] There are many ways to set the positioning member 42 as a light-shielding member. Two possible methods are listed below as examples: one is to use light-shielding materials to manufacture the positioning member 42, such as using opaque plastic, or adding light-shielding fillers to plastic particles for manufacturing; the other is to spray or electroplate a light-shielding coating on the surface of the translucent material. For example, when the material of the positioning member 42 is optical silicone, a light-shielding metal layer can be electroplated on the surface of the positioning member 42.

[0086] In some implementations of the embodiments of the present application, Fig.10 and Fig.11As shown, the camera assembly structure also includes a mounting base 6 and a decorative member 7; wherein the mounting base 6 is connected to the side of the circuit board 3 away from the camera module 2; the decorative member 7 is connected to the mounting base 6, and the light-transmitting protective screen 5 is connected to the side of the decorative member 7 away from the circuit board 3, the decorative member 7 has a first opening 71, and the light-transmitting cover 4 passes through the first opening 71 and is connected to the light-transmitting protective screen 5, and the light-transmitting cover 4 is against the inner wall of the first opening 71.

[0087] The decorative piece 7 is a component used to decorate the camera module 2, and is commonly found in the rear camera of a mobile phone. From the appearance point of view, the camera module 2 equipped with the decorative piece 7 is more beautiful, and the user has a better visual experience. At the same time, the decorative piece 7 can also play a role in fixing and positioning the camera module 2. The decorative piece 7 and the circuit board 3 are generally fixed on the mounting base 6, and the mounting position of the decorative piece 7 is determined based on the position of the camera module 2.

[0088] Take the assembly of the rear camera of a mobile phone as an example. Fig.11 As shown, first, the circuit board 3 (usually the main board) is fixed on the mounting base 6 (usually the middle frame), and then the camera module 2 is connected to the circuit board 3. After that, the decorative part 7 can be bonded to the cover body (usually the battery cover), and the cover body bonded with the decorative part 7 is assembled with the mounting base 6, the camera module 2 is located in the first opening 71 of the decorative part 7, and then the optical silicone is injection molded onto the light-transmitting protective screen 5 (usually the rear camera lens) to form a light-transmitting cover 4, and finally, glue is applied to the side of the light-transmitting protective screen 5 facing the decorative part 7 to make it bonded to the decorative part 7. At this time, the light-transmitting cover 4 enters the first opening 71 and covers the camera module 2, thus completing the assembly of the entire camera module 2.

[0089] In the related art, the camera module is sealed by bonding the sealing foam to the decorative part, but the sealing foam is easy to be attached to the side, so that dust and liquid can easily enter the interior of the body through the gap and affect the performance of the electronic device.

[0090] like Fig.12 and Fig.13 As shown, in some implementations of the present application, the light-transmitting cover 4 further includes a sealing plate 43, which is connected to the soft light-transmitting plate 41 in the circumferential direction thereof, and the light-transmitting protective screen 5 is connected to the decorative element 7 via the sealing plate 43. Fig.13The sealing plate 43 is arranged between the light-transmitting protective screen 5 and the decorative member 7, which can effectively prevent water or dust from entering the interior of the body from the edge of the light-transmitting protective screen 5 and the limiting opening 511 of the light-transmitting protective screen 5, thus meeting the waterproof and dustproof design requirements of the electronic device. In addition, since the sealing plate 43 is connected to the decorative member 7 together with the soft light-transmitting plate 41 and the positioning member 42, and the positioning member 42 will be assembled into the first opening 71 of the decorative member 7, the position of the sealing plate 43 and the decorative member 7 is relatively fixed, and there will be no gap leakage due to installation deviation.

[0091] The material of the sealing plate 43 can be selected according to actual needs, such as rubber, silicone, etc., as long as it can meet the sealing requirements. In a possible design, the sealing plate 43 can be made of optical silicone material, and the sealing plate 43 and the soft light-transmitting plate 41 are an integrated structure, thereby reducing the difficulty of processing. The sealing plate 43 and the soft light-transmitting plate 41 are formed at the same time during in-mold injection molding.

[0092] In some embodiments of the present application, the sealing plate 43 may be a light shielding member. Setting the sealing plate 43 as a light shielding member can prevent the adjacent cameras from cross-talking with each other and affecting the imaging effect, and can also reduce the impact of light reflection on the imaging. Among them, similar to the way of setting the positioning member 42 as a light shielding member, the sealing plate 43 can also be made of a light shielding material, or a light shielding coating can be sprayed or electroplated on the surface, which will not be described in detail in this embodiment.

[0093] In summary, in the camera assembly structure provided in the embodiment of the present application, the camera module 2 is installed and positioned by the transparent cover 4, wherein the hardness of the soft transparent plate 41 of the transparent cover 4 is very small, so the transparent cover 4 can be zero-matched with the lens 22 of the camera module 2 in the Z direction of the fuselage, and at this time, the soft transparent plate 41 is in direct contact with the lens, ensuring that the viewing angle range of the lens 22 is not affected while also reducing the size of the transparent window, so that the lens 22 does not protrude excessively from the shell surface of the electronic device; the positioning member 42 of the transparent cover 4 is opaque and surrounds the camera module 2, ensuring that adjacent lenses 22 do not cross-light with each other, and precisely because the transparent cover 4 is zero-matched with the lens 22, the lens 22 and the soft transparent plate 41 have a direct positioning relationship, and there will be no eccentricity; the sealing plate 43 of the transparent cover 4 surrounds the soft transparent plate 41 and is configured as a light-shielding member, which can not only play a waterproof and dustproof effect, but also avoid the influence of cross-light and light reflection on the camera imaging effect. Therefore, the camera assembly structure provided in the embodiment of the present application is compact, which is conducive to achieving a lightweight and thin body of the electronic device, while also ensuring a good imaging effect of the camera.

[0094] The embodiment of the present application also provides an electronic device, which includes the above-mentioned camera assembly structure. Exemplarily, the electronic device can be a device with a shooting function such as a mobile phone, a tablet computer, a laptop computer, a display, a camera, etc.
