The rear cover assembly also includes a first housing, a second housing, a light-transmitting element, and a second adhesive layer. The first housing is snapped onto the decorative element such that a portion of the first housing is inserted into the second through hole. The first housing has a first light-transmitting hole. The light-transmitting element covers the first light-transmitting hole and is fixedly connected to the first housing. The second housing is snapped onto the inner side surface, and a portion of the second housing is inserted into the first through hole and fixedly connected to the first housing. The second housing has a second light-transmitting hole communicating with the first light-transmitting hole.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0039] Currently, mobile phones, tablets, and other electronic devices have become indispensable technological products in people's lives, studies, and entertainment, bringing them numerous conveniences and enjoyment. With the diversification of electronic device functions, there are now many types and brands of electronic devices, providing consumers with a wide range of choices.

[0040] As people's demands for video quality increase, the performance of camera modules installed in electronic devices is becoming more and more powerful, and their space requirements are also increasing. In order to improve the performance of camera modules, thicker lens assemblies are usually required.

[0041] In related technologies, the lens assembly of a camera module is relatively thick, necessitating a protrusion from the back cover assembly of the electronic device. To integrate and protect the camera module, the back cover assembly typically incorporates protruding decorative elements to minimize its impact on the overall appearance of the electronic device. However, traditional back cover assemblies rely on adhesive layers for bonding, but due to structural limitations of the cover itself, these adhesive layers occupy significant thickness space. This results in the back cover assembly taking up considerable thickness space within the electronic device, hindering the pursuit of a thinner and lighter design.

[0042] Based on this, the present disclosure provides a cover plate that can reduce the maximum thickness of the back cover assembly by optimizing the structure, thereby reducing the thickness space occupied by the electronic device and contributing to the thinning and lightening of the electronic device.

[0043] To better understand the cover plate of this disclosure, the following description is based on an electronic device that uses the cover plate of this disclosure.

[0044] like Figures 1 to 3 As shown, in some embodiments of this disclosure, an electronic device 1 is provided, including a mid-frame 10, a camera module 20, and a back cover assembly 30.

[0045] like Figure 3 , Figure 5 as well as Figure 6 As shown, the back cover assembly 30 includes a cover plate 100, a decorative element 200, and a first adhesive layer 300. The cover plate 100 includes a plate body 110, which includes a back surface 111 and a mounting portion 112 disposed on the back surface 111. The mounting portion 112 includes an annular bearing surface 101 protruding from the back surface 111, a first through hole 102 disposed within the annular bearing surface 101, and a first adhesive groove 103 disposed between the outer edge of the first through hole 102 and the annular bearing surface 101. The annular bearing surface 101 supports the decorative element 200. The decorative element 200 abuts against the annular bearing surface 101. At least a portion of the first adhesive layer 300 is disposed within the first adhesive groove 103 to bond and fix the decorative element 200 to the mounting portion 112. The decorative element 200 has a light-transmitting area 211 corresponding to the first through hole 102.

[0046] The middle frame 10 is fixedly connected to the plate body 110 to form a protective cavity (not shown). The camera module 20 is disposed inside the protective cavity and can receive light through the light-transmitting area 211. In this way, the camera module 20 can be protected by the rear cover assembly 30 and the middle frame 10, and can receive external light through the light-transmitting area 211 to realize the camera function of the electronic device 1.

[0047] During assembly of the back cover assembly 30, the decorative element 200 abuts against the annular bearing surface 101, and is bonded and fixed to the mounting portion 112 by at least a portion of the first adhesive layer 300 being embedded in the first adhesive groove 103, thus assembling the decorative element 200 onto the cover plate 100. Since the cover plate 100 can fully utilize the thickness space of the mounting portion 112 to accommodate the first adhesive layer 300, the thickness space occupied by the first adhesive layer 300 in the back cover is reduced, thereby reducing the maximum thickness of the back cover assembly 30 and consequently reducing its footprint in the electronic device 1, which is beneficial for making the electronic device 1 thinner and lighter.

[0048] Furthermore, it can be understood that since at least a portion of the first adhesive layer 300 is embedded in the first adhesive groove 103, the fitting between the decorative element 200 and the annular bearing surface 101 is more compact, which helps to improve the overall aesthetics of the back cover assembly 30.

[0049] Reference Figure 7 As shown, the thickness direction of the board body, the thickness direction of the back cover assembly, and the thickness direction of the electronic device are all set in the same direction, which is the Z-axis direction.

[0050] like Figure 6 as well as Figure 7 As shown, in some embodiments, the annular bearing surface 101 is attached to the decorative element 200. In this way, the decorative element 200 and the annular bearing surface 101 are tightly attached, so that the cover plate 100 and the decorative element 200 are assembled into a whole, which helps to further improve the overall aesthetics of the rear cover assembly 30.

[0051] Furthermore, since the annular bearing surface 101 fits snugly against the decorative part 200, achieving a seamless assembly, it makes it difficult for external liquids and dust to enter the protective cavity, further enhancing the protective performance of the electronic device 1.

[0052] In some embodiments, the annular bearing surface 101 is mirror-like. This makes the surface of the annular bearing surface 101 smooth, facilitating a tight fit with the assembly and achieving seamless assembly.

[0053] Optionally, in some embodiments, the plate body 110 is made of glass. The decorative element 200 is also made of glass. In this way, the annular bearing surface 101 is mirror-like, which allows for a better seamless fit with the decorative element 200, enhancing the sophistication of the electronic device.

[0054] Optionally, when the electronic device is a mobile phone, tablet, in-vehicle screen, smartwatch, etc., the board body is the battery back cover, which can be made of cold-carved glass, which helps to further improve the sophistication of the electronic device.

[0055] Reference Figure 3 , Figure 6 as well as Figure 7 It is understood that in some embodiments, the first adhesive groove 103 is annular and the first adhesive layer 300 is also annular, so that the decorative element 200 is sealed to the panel body 110.

[0056] like Figure 4 as well as Figure 7 As shown, in some embodiments, the plate body 110 further includes an inner side surface 113 spaced apart from the back surface 111 along the thickness direction of the plate body 110. The cover plate 100 also includes a first diaphragm 120 covering the inner side surface 113. Thus, the first diaphragm 120 can cooperate with the plate body 110 to at least improve the strength of the cover plate 100 and / or at least improve the appearance of the cover plate 100.

[0057] In conjunction with the foregoing embodiments, the material of the plate body 110 is glass. By using the first diaphragm 120 in conjunction with the plate body 110, the appearance and texture of the cover plate 100 can be improved. Optionally, the first diaphragm 120 has at least one of the following characteristics: stripes, light-blocking properties, and brightening effect.

[0058] like Figure 6 as well as Figure 7As shown, in some embodiments, the first diaphragm 120 is provided with a first clearance hole 121. At least a portion of the first clearance hole 121 is disposed around the first through hole 102 to form a second adhesive groove 130 on the inner side surface 113. The light-transmitting area 211 includes a second through hole 201 communicating with the first through hole 102. The rear cover assembly 30 also includes a first housing 400, a second housing 600, a light-transmitting element 500, and a second adhesive layer 700. The first housing 400 is snapped onto the decorative element 200 such that a portion of the first housing 400 is inserted into the second through hole 201. The first housing 400 is provided with a first light-transmitting hole 410. The light-transmitting element 500 covers the first light-transmitting hole 410 and is fixedly connected to the first housing 400. The second housing 600 is snapped onto the inner side surface 113, and a portion of the second housing 600 is inserted into the first through hole 102 and is fixedly connected to the first housing 400. The second housing 600 is provided with a second light-transmitting hole 610 communicating with the first light-transmitting hole 410. At least a portion of the second adhesive layer 700 is disposed within the second adhesive groove 130 to bond and fix the second housing 600 to the plate body 110. Thus, the first housing 400 is bonded and fixed to the inner side surface 113 by at least a portion of the second adhesive layer 700 being embedded in the second adhesive groove 130, assembling the second housing 600 onto the cover plate 100. The first housing 400 is also snapped onto the decorative piece 200, allowing a portion of the first housing 400 to be inserted into the second through hole 201. It is then fixedly connected to the second housing 600, integrating the first housing 400 into the cover plate 100 as well. The light-transmitting element 500 protects the first light-transmitting hole 410, preventing external liquids and dust from entering the protective cavity, while allowing external light to pass through the light-transmitting element 500 and enter the camera module 20. Since the first diaphragm 120 can avoid the second adhesive layer 700 through the first clearance hole 121, the thickness space occupied by the second adhesive layer 700 in the back cover is reduced, thereby reducing the maximum thickness of the back cover assembly 30 and reducing the thickness space occupied by it in the electronic device 1, which is conducive to the thinning and lightening of the electronic device 1.

[0059] Furthermore, it is understandable that the cooperation of the first housing 400, the second housing 600 and the light-transmitting element 500 facilitates the formation of different light-transmitting protective structures on the rear cover assembly 30 to meet the protection and light-transmitting requirements of the camera module 20.

[0060] In some embodiments, the first housing 400 is made of a wear-resistant material, and the light-transmitting element 500 is embedded in the first housing 400. In this way, the first housing 400 can prevent the light-transmitting element 500 from being scratched, ensuring the reliability of the light transmission of the light-transmitting element 500.

[0061] Optionally, such as Figure 5 as well as Figure 6As shown, in some embodiments, the second light-transmitting hole 610 includes at least two, and is spaced apart on the second housing 600. The first housing 400 and the light-transmitting element 500 correspond one-to-one with the second light-transmitting hole 610, and are respectively fixedly connected to the second housing 600. The first light-transmitting element corresponds one-to-one with the first housing 400. In this way, it is convenient to form at least two light-transmitting structures on the second housing 600 to accommodate at least two camera modules 20.

[0062] Furthermore, the second housing 600 can fully utilize the area space of the first through hole 102 to provide at least two second light-transmitting holes 610, facilitating the integration of other structural components on the second housing 600. For example, LDS antennas, supplementary lighting, and other structures.

[0063] Furthermore, in some embodiments, the second adhesive groove 130 is annular, and the second adhesive layer 700 is also annular, so that the second housing 600 is sealed to the plate body 110. Thus, by using the annular second receiving groove to accommodate the annular second adhesive layer 700, it is convenient to form an annular sealing structure between the plate body 110 and the second housing 600 using the second adhesive layer 700, thereby achieving a sealed and fixed connection between the second housing 600 and the plate body 110.

[0064] like Figure 7 As shown, in some embodiments, the decorative element 200 includes a decorative body 210 with a light-transmitting area 211 and a second film 220 fixed to the decorative body 210. The decorative body 210 is in contact with the annular bearing surface 101. At least a portion of the second film 220 is embedded in the first adhesive groove 103 and is bonded to the first adhesive layer 300. The second film 220 is provided with a second clearance hole to avoid the light-transmitting area 211. Thus, at least a portion of the second film 220 is embedded in the first adhesive groove 103 and bonded to the first adhesive layer 300, which facilitates the contact between the decorative body 210 and the annular bearing surface 101, making the decorative element 200 fit tightly against the board body 110. Since at least a portion of the second diaphragm 220 is embedded in the first adhesive groove 103 and bonded to the first adhesive layer 300, the first adhesive layer 300 is completely embedded in the first adhesive groove 103. This also reduces the thickness space of the back cover occupied by the second diaphragm 220, thereby reducing the maximum thickness of the back cover assembly 30 and thus reducing the thickness space it occupies in the electronic device 1, which is beneficial for making the electronic device 1 thinner and lighter.

[0065] In conjunction with the foregoing embodiments, the decorative element 200 is made of glass. By using the second diaphragm 220 in conjunction with the decorative element 200, the appearance and texture of the back cover can be enhanced. Optionally, the second diaphragm 220 has at least one of the following characteristics: stripes, light-blocking properties, and brightening effect.

[0066] In some embodiments, the second adhesive groove 130 is disposed on the inner side of the annular bearing surface 101 on the orthogonal projection plane in the thickness direction of the plate body 110. In this way, the second adhesive layer 700 can be shielded by the first diaphragm 120, thus avoiding any adverse effects of the second adhesive layer 700 on the appearance and texture of the back cover assembly 30.

[0067] Optionally, on the orthographic projection surface of the plate body 110 in the thickness direction, the first diaphragm 120 and the second diaphragm 220 are overlapped to improve the appearance consistency of the back cover assembly 30.

[0068] In some embodiments, the back cover assembly 30 further includes a third adhesive layer 800. The third adhesive layer 800 is sandwiched between the first housing 400 and the second housing 600 to bond and fix the first housing 400 and the second housing 600. This facilitates the fixed connection of the first housing 400 and the second housing 600 using the third adhesive layer 800, and makes it easy to assemble the first housing 400 and the second housing 600 onto the panel body 110 and the decorative element 200.

[0069] It should be noted that there are various ways to implement the first adhesive layer 300, the second adhesive layer 700 and the third adhesive layer 800, including but not limited to adhesive, adhesive cloth, etc.

[0070] Optionally, the first adhesive layer 300, the second adhesive layer 700, and the third adhesive layer 800 are formed by dispensing.

[0071] It should be noted that there are several ways to achieve the light-transmitting area, for example, through... Figure 7 The second through-hole is formed as shown. For example, in some other embodiments, the light-transmitting area is formed by... Figure 8 The enclosed light-transmitting section shown is formed.

[0072] Understandably, the technical solution disclosed herein utilizes a back cover assembly to protect the camera module while allowing external light to enter the camera module through the light-transmitting area. Furthermore, reducing the maximum thickness of the back cover assembly reduces the bulkiness of the electronic device and enhances its aesthetic appeal.

[0073] The electronic device 1 disclosed herein includes ranging devices, scanning devices, shooting devices, handheld devices, wearable devices (e.g., smartwatches), monitoring devices, cellular phones, smartphones, tablet computers, laptop computers, in-vehicle computers, and other devices with camera functions.
