DETAILED DESCRIPTION

[0037] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those of ordinary skill in the art. Some technical terms appearing in the embodiments of the present application are explained below.

[0038] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] In electronic devices such as mobile phones, metal decorative parts are often used to decorate the camera module. Metal decorative parts are often close to the frame antenna of the electronic device, which will compress the antenna clearance and cause an overall decrease in radiation efficiency. Some antennas will even generate clutter due to the influence of metal decorative parts, causing a sharp drop in radiation efficiency.

[0040] At present, in conventional technology, interference is often destroyed by adding grounding at the corresponding position of the metal decorative part, but this method still cannot solve the problem that the metal decorative part compresses the antenna clearance and causes the antenna radiation efficiency to decrease.

[0041] In order to solve the above technical problems, an embodiment of the present application provides a housing assembly and an electronic device.

[0042] like Figure 1 and Figure 2 As shown, the housing assembly includes a frame antenna 1, a back cover 2, a metal decorative part 3 and a connector 4. The housing assembly can be applied to electronic devices, including but not limited to mobile phones, tablet computers, laptop computers, vehicle-mounted devices, wearable devices, drones and other products. The wearable devices can be smart bracelets, smart watches, augmented reality (AR) glasses, virtual reality (VR) glasses and the like.

[0043] The frame antenna 1 is made of metal material and is roughly annular. For example, the frame antenna 1 is connected end to end to form a complete ring; or the shape formed by the frame antenna 1 has a gap or a gap, so that the frame antenna 1 is annular with a gap.

[0044] The frame antenna 1 is located around the back cover 2. The back cover 2 covers the frame antenna 1. The back cover 2 and the frame antenna 1 surround and form a receiving cavity, which is used to accommodate various parts or electronic devices of the electronic device.

[0045] The metal decoration part 3 is arranged on the back cover 2. The metal decoration part 3 is made of metal material. The metal decoration part 3 can be designed with texture or color and can be used to decorate the camera module of the electronic device.

[0046] The metal decorative part 3 may be in the form of a square, a rectangle, a circle, a rounded rectangle, etc. The embodiment of the present application is described by taking the metal decorative part 3 in the form of a rounded rectangle as an example.

[0047] The connecting member 4 is disposed on a side of the metal decorative member 3 close to the back cover 2 . The connecting member 4 is conductively connected to the metal decorative member 3 . The connecting member 4 has a first grounding portion 44 for grounding.

[0048] Specifically, Figure 1 As shown, a mounting hole 21 is provided on the back cover 2 , the metal decorative part 3 covers the mounting hole 21 , and the connecting part 4 is located on a side of the metal decorative part 3 close to the accommodating cavity.

[0049] The connector 4 has the ability to conduct electricity. The connector 4 can be connected to the metal decorative part 3 through a conductive element, or a part of the connector 4 itself can be in direct contact with the metal decorative part 3 , thereby achieving a conductive connection between the connector 4 and the metal decorative part 3 .

[0050] When the shell assembly is applied to an electronic device, the middle frame, circuit board and other components in the electronic device have an equivalent ground area for grounding. The connector 4 can be conductively connected to the equivalent ground area inside the electronic device through the first grounding portion 44, thereby achieving a conductive connection between the metal decorative part 3 and the equivalent ground area. When the frame antenna 1 is working, a high-order circulation mode between the connector 4 and the metal decorative part 3 can be stimulated, thereby improving the radiation efficiency and performance of the frame antenna 1 whose clearance is occupied by the metal decorative part 3.

[0051] The shell assembly provided in the embodiment of the present application can connect the connector 4 to the equivalent ground in the electronic device by setting the connector 4 to have a first grounding portion 44. Since the connector 4 is conductively connected to the metal decorative part 3, a conductive connection between the metal decorative part 3 and the equivalent ground can be achieved, thereby stimulating a high-order circulation mode between the connector 4 and the metal decorative part 3 when the border antenna 1 is working, thereby assisting the border antenna 1 to radiate and improving the performance of the border antenna 1.

[0052] In a specific embodiment, the connecting member 4 is a metal member.

[0053] For example, the connector 4 is made of steel material. The connector 4 is a steel sheet, which not only has electrical conductivity but also has good strength, plasticity, and toughness.

[0054] In a specific embodiment, the connecting member 4 and the metal decorative member 3 are electrically connected by one or more of conductive foam, conductive threaded fasteners and conductive springs.

[0055] Exemplarily, the connector 4 is connected to the metal decorative part 3 via a conductive threaded fastener, which not only enables a conductive connection between the connector 4 and the metal decorative part 3 , but also fixes the connector 4 , thereby ensuring the stability and reliability of the connection between the connector 4 and the metal decorative part 3 .

[0056] In a specific embodiment, the connector 4 includes a main body 41 and a branch portion 42 that are connected to each other. The branch portion 42 is located on a side of the main body 41 close to the frame antenna 1 .

[0057] The branch portion 42 may be one or more, for example Figure 3 As shown, there are two branch portions 42 .

[0058] The branch portion 42 is closer to the frame antenna 1 than the main portion 41. Figure 3 As shown, the branch portion 42 located above the main body 41 extends in the left-right direction and is close to the upper edge of the metal decorative part 3, and the branch portion 42 is close to the border antenna 1 above it; the branch portion 42 located on the right side of the main body 41 extends in the up-down direction and is close to the right edge of the metal decorative part 3, and the branch portion 42 is close to the border antenna 1 on its right side.

[0059] The provision of the branch portion 42 helps to enhance the performance of the region adjacent to the branch portion 42 in the frame antenna 1 , thereby improving the radiation efficiency of the frame antenna 1 .

[0060] The length of the branch portion 42 can be set based on the electrical length of the corresponding frequency band of the frame antenna 1. For example, when the wavelength and electrical length of the electromagnetic wave in the corresponding frequency band are known, the length of the branch portion 42 can be calculated by reverse calculation based on the calculation formula of the electrical length.

[0061] In a further embodiment, the orthographic projection of the branch portion 42 on the back cover 2 at least partially overlaps with the orthographic projection of the metal decorative component 3 on the back cover 2 .

[0062] like Figure 3 As shown, the metal decorative part 3 is provided with four circular mounting holes 31, and the mounting holes 31 are used to mount components or electronic devices such as cameras of electronic devices. Most of the orthographic projections of the branch portions 42 on the back cover 2 overlap with the orthographic projections of the metal decorative part 3 on the back cover 2, so that the branch portions 42 can avoid the mounting holes 31 and avoid affecting the installation of components or electronic devices such as cameras.

[0063] In a specific embodiment, the border antenna 1 is in the shape of a rectangular ring, and the border antenna 1 includes two relatively arranged wide sides 11 and two relatively arranged long sides 12. There are multiple branch portions 42, at least one branch portion 42 is located on the side of the main body 41 close to the wide side 11, and at least one branch portion 42 is located on the side of the main body 41 close to the long side 12.

[0064] For example, Figure 2As shown, the two long sides 12 are opposite to each other along the width direction of the frame antenna 1, the two wide sides 11 are opposite to each other along the length direction of the frame antenna 1, the metal decorative part 3 is located at the upper left of the back cover 2, and the metal decorative part 3 is close to one of the wide sides 11 and one of the long sides 12 of the frame antenna 1.

[0065] By setting at least one branch portion 42 on the side of the main body 41 close to the wide side 11, the branch portion 42 is used to enhance the radiation efficiency and performance of the border antenna 1 at the wide side 11; by setting at least one branch portion 42 on the side of the main body 41 close to the long side 12, the branch portion 42 is used to enhance the radiation efficiency and performance of the border antenna 1 at the long side 12.

[0066] Exemplarily, the wide side 11 of the frame antenna 1 is an N77+5G antenna, and the long side 12 of the frame antenna 1 is a 5G antenna. When the wide side 11 of the frame antenna 1 operates in the N77 frequency band, a circulation pattern is formed between the branch portion 42 and the metal decorative part 3, and the metal decorative part 3 assists the antenna in radiation.

[0067] Figure 5 The figure shows the signal strength of the frame antenna 1 in the embodiment of the present application and the frame antenna 1 in the conventional housing assembly at different frequencies, wherein the conventional housing assembly is only provided with the frame antenna 1 and the metal decorative part 3, but not with the connector 4. Figure 5 The horizontal axis represents the frequency in MHz, and the vertical axis represents the signal strength in dB. Figure 5 As shown, within the range of 3300MHz to 4200MHz corresponding to the N77 frequency band, the signal strength corresponding to the border antenna 1 in the embodiment of the present application is significantly higher than the signal strength corresponding to the border antenna 1 in the conventional shell assembly, and the difference between the two is up to about 1dB.

[0068] Therefore, according to Figure 5 It can be concluded that the shell assembly provided in the embodiment of the present application can improve the radiation efficiency and signal strength of the frame antenna 1 by providing the branch portion 42 .

[0069] In a further embodiment, connecting portions 43 are provided at both ends of the branch portion 42 in the length direction, and the connecting portions 43 are used to connect to the metal decorative part 3; and a first grounding portion 44 is provided at at least one end of the branch portion 42 in the length direction.

[0070] For example, Figure 4 As shown, each branch portion 42 is provided with a connecting portion 43 at both ends in the length direction, and a conductive threaded fastener is inserted into the connecting portion 43 to conductively connect the branch portion 42 and the metal decorative part 3. A first grounding portion 44 is provided at the right end of the branch portion 42 located at the top, and a first grounding portion 44 is provided at the upper end of the branch portion 42 located at the bottom.

[0071] By setting connecting parts 43 at both ends of the branch part 42 in the length direction, the connection stability and reliability between the branch part 42 and the metal decorative part 3 can be improved, and the normal conductive connection between the branch part 42 and the metal decorative part 3 can be fully ensured; by setting a first grounding part 44 at at least one end of the branch part 42 in the length direction, the floor current can be coupled.

[0072] In a specific embodiment, the trunk portion 41 is in a cross shape, and the trunk portion 41 is provided with a connecting portion 43 and a first grounding portion 44 .

[0073] like Figure 3 As shown, the "cross"-shaped main body 41 is located between the four mounting holes 31 of the metal decorative part 3, and avoids the four mounting holes 31. By setting the main body 41 in a "cross" shape, not only the material used is saved, but also the installation of components or electronic devices such as cameras can be prevented from being affected.

[0074] like Figure 4 As shown, the ends and intersections of the main body 41 are provided with connecting parts 43 . Exemplarily, conductive threaded fasteners are inserted into the connecting parts 43 to conductively connect the main body 41 and the metal decorative part 3 .

[0075] In one embodiment, the shell assembly further includes a middle frame, which is located in a receiving cavity formed by the back cover 2 and the frame antenna 1 , and has a second grounding portion connected to the first grounding portion 44 .

[0076] In this embodiment, the connector 4 is conductively connected to the second grounding portion of the middle frame through the first grounding portion 44, thereby realizing a conductive connection between the metal decorative portion 3 and the middle frame. When the border antenna 1 is working, a high-order circulation mode between the connector 4 and the metal decorative portion 3 can be stimulated, thereby improving the radiation efficiency and performance of the border antenna 1 whose clearance is occupied by the metal decorative portion 3.

[0077] Optionally, when the housing assembly is applied to an electronic device, components such as a circuit board in the electronic device also have a second grounding portion.

[0078] In one embodiment, the distance between the edge of the metal decoration part 3 and the frame antenna 1 is less than or equal to 4 mm.

[0079] When the metal decorative part 3 is close to the frame antenna 1, the metal decorative part 3 is likely to affect the radiation efficiency of the frame antenna 1. Therefore, in the prior art, the size of the metal decorative part 3 is often reduced, thereby increasing the distance between the metal decorative part 3 and the frame antenna 1. However, the housing assembly provided in the embodiment of the present application can improve the radiation efficiency and performance of the frame antenna 1 whose clearance is occupied by the metal decorative part 3 by providing the connecting part 4, thereby allowing the distance between the edge of the metal decorative part 3 and the frame antenna 1 to be reduced to less than 4 mm.

[0080] An embodiment of the present application also provides an electronic device, comprising a housing assembly provided by any of the above embodiments.

[0081] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
