[0041] To make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific implementation manners and are not intended to limit the present disclosure.

[0043] Electronic devices such as mobile phones, tablet computers, and communication watches have become essential technological products in people's lives, learning, and entertainment. With the development of the diversification of the functions of electronic devices, there are a wide variety of electronic device types and brands, making the electronic devices available for consumers to choose from also numerous. How to gain the favor of consumers has become an increasingly important issue for electronic device manufacturers.

[0044] Currently, with the development of electronic devices, the integration of electronic devices is getting higher and higher. At the same time, in order to adapt to miniaturization, the gaps between electronic components inside the electronic devices are getting smaller and the layout is getting more compact, which also increases the difficulty of antenna layout in electronic devices.

[0045] However, in the related technologies, the structure of the electronic device is getting more and more compact. The radiation performance of the frame antenna is easily affected by other metal devices, and the layout space is limited, which increases the difficulty of the structural arrangement of the electronic device. For example, an electronic device usually increases the length of the radiation arm of the antenna to improve the radiation performance of the antenna. However, this will result in insufficient clearance space for the antenna. If the clearance space for the antenna is to be satisfied, the radiation performance of other antennas adjacent to the antenna will be reduced, thereby increasing the difficulty of antenna arrangement in the electronic device.

[0046] Based on this, it is necessary to provide a housing component that makes full use of the internal space of the housing component to arrange the antenna. At the same time, it does not rely on increasing the length dimension of the radiation arm of the antenna to improve the radiation performance, so that there is sufficient clearance space between other antennas adjacent to the antenna, thereby being able to avoid or reduce the adverse effects on adjacent antennas and being beneficial to reducing the difficulty of the structural arrangement of the electronic device.

[0047] To better understand the housing component of the present disclosure, the following will be described in conjunction with an electronic device applying the housing component.

[0048] As Figures 1 to 4As shown, in some embodiments, an electronic device 1 is provided, which includes a housing component 10 and a control component 20. The housing component 10 includes a housing assembly 100 and a circuit board 200. The housing assembly 100 includes a metal carrier plate 110 and a first antenna 121. The metal carrier plate 110 includes a first grounding portion 111 and a second grounding portion 112 that is spaced apart from the first grounding portion 111 in a first direction to form a groove 113. A part of the first antenna 121 is spaced apart from the metal carrier plate 110 to form a first antenna slot 101. One end of the first antenna 121 is grounded and connected to the metal carrier plate 110. The circuit board 200 is disposed in the housing assembly 100. The circuit board 200 includes a feeding circuit 210 and a grounding layer 220. The feeding circuit 210 is in feeding cooperation with the other end of the first antenna 121. The grounding layer 220 includes a first grounding terminal 221 connected to the first grounding portion 111 and a second grounding terminal 222 grounded and connected to the second grounding portion 112. Wherein, the first direction is set in the same direction as the radiation length direction of the first antenna 121. The control component 20 is disposed on the circuit board 200 and is electrically connected to the feeding circuit 210.

[0049] When the electronic device 1 communicates with other devices, the first antenna 121 is controlled by the control component 20 to enable the first antenna 121. The first grounding portion 111 is grounded and connected to the first grounding terminal 221 and the second grounding portion 112 is grounded and connected to the second grounding terminal 222, so that the metal carrier plate 110 and the grounding layer 220 are used as the ground of the first antenna 121. At this time, by setting the groove 113, the first grounding portion 111 and the second grounding portion 112 are spaced apart in the first direction, thereby changing the direction of the return ground current between the metal carrier plate 110 and the grounding layer 220 to improve the radiation efficiency of the first antenna 121. In this way, the housing component 10 can improve the radiation performance without relying on changing the length dimension of the radiation arm 1211 of the first antenna 121, so that there is enough clearance space between the first antenna 121 and other adjacent antennas, thereby avoiding or reducing the adverse effects on adjacent antennas and reducing the difficulty of antenna arrangement of the electronic device 1.

[0050] In addition, the first antenna 121 does not occupy too much space of the housing assembly 100, so that the housing assembly 100 can flexibly arrange other antennas, further improving the structural compactness of the electronic device 1 and facilitating the miniaturization of the electronic device 1.

[0051] It should be noted that the specific implementation manner of the feeding circuit 210 can be various as long as it can realize the feeding of the first antenna 121. For example, the feeding circuit 210 is a feeding network disposed on the circuit board 200.

[0052] In some embodiments, the feeding circuit 210 further includes a tuning unit and / or an impedance matching unit, etc.

[0053] It should be noted that the specific implementation of the grounding layer 220 can be various, as long as it can cooperate with the metal carrier plate 110 to achieve the grounding of the first antenna 121. For example, the grounding layer 220 is a grounding network and is disposed on the circuit board 200. For example, the circuit board 200 includes a metal layer, and at least a part of the metal layer is the grounding layer 220.

[0054] It should be noted that the radiation frequency band of the first antenna 121 can be flexibly designed according to actual needs. For example, the radiation frequency band of the first antenna 121 is a low-frequency band, a medium-frequency band, a high-frequency band, and so on.

[0055] In some embodiments, the radiation frequency band of the first antenna 121 is one of the MHB frequency band, the N79 frequency band, the N78 frequency band, the N77 frequency band, and the WIFI 5G frequency band.

[0056] Among them, the MHB frequency band is 1700 MHz to 2700 MHz, including the 3G and 4G frequency bands. In addition, the 5G frequency band of China Mobile is 4800 MHz to 4900 MHz, a total of 100 MHz, and the frequency band number is N79. The 5G frequency band of China Telecom is 3400 MHz to 3500 MHz, a total of 100 MHz, and the frequency band number is N78. The 5G frequency band of China Unicom is 3500 MHz to 3600 MHz, a total of 100 MHz, and the frequency band number is N77. The WIFI 5G frequency band includes CH149.

[0057] In one example, the radiation frequency band of the first antenna 121 is the WIFI 5G frequency band.

[0058] Refer to Figures 1 to 4 As shown, the width direction of the housing assembly 100, the width direction of the electronic device 1, and the first direction are arranged in the same direction, which is the X-axis direction. The length direction of the housing assembly 100, the length direction of the electronic device 1, and the second direction are arranged in the same direction as the Y-axis direction. The thickness direction of the metal carrier plate 110 and the thickness direction of the electronic device 1 are arranged in the same direction, which is the Z-axis direction.

[0059] In some embodiments, the length of the groove 113 is λ / 2, where λ is the wavelength of the radiation frequency band of the first antenna 121. Thus, according to the theoretical derivation formula λ*f = V, V = C / √ε. Wherein, F is the frequency of the radiation frequency band of the first antenna 121. C is the propagation speed of electromagnetic waves in a vacuum. v is the propagation speed of electromagnetic waves in the air. ε is the dielectric constant of the air, and the length of λ can be calculated, and then the length of the groove 113 can be obtained. It is convenient to improve the radiation efficiency of the first antenna 121 by changing the direction of the ground current between the metal carrier plate 110 and the grounding layer 220.

[0060] Optionally, as Figure 4As shown, in some embodiments, when the radiation frequency band of the first antenna 121 is the WIFI 5G frequency band, the length of the groove 113 is A, and A = 14 mm to 15 mm. In this way, by optimizing the length of the groove 113, the radiation efficiency of the first antenna 121 in the WIFI 5G frequency band can be further improved.

[0061] Optionally, in some embodiments, A = 14.3 mm to 14.7 mm.

[0062] Optionally, in some embodiments, A is one of 14 mm, 14.1 mm, 14.2 mm, 14.3 mm, 14.4 mm, 14.45 mm, 14.5 mm, 14.55 mm, 14.6 mm, 14.7 mm, 14.75 mm, 14.8 mm, 14.9 mm, 15 mm, etc.

[0063] As Figure 4 shown, in some embodiments, the width of the groove 113 is B, and B = 2 mm to 4 mm. In this way, by optimizing the width of the groove 113, the radiation efficiency of the first antenna 121 in the WIFI 5G frequency band can be further improved.

[0064] Combined with the foregoing embodiments of the length of the groove 113, by adjusting the length dimension and / or width dimension of the groove 113, the radiation efficiency of the first antenna 121 can be flexibly adjusted, making the design of the first antenna 121 more flexible.

[0065] Optionally, in some embodiments, B = 2.5 mm to 3.5 mm.

[0066] Optionally, in some embodiments, B is one of 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, etc.

[0067] Referring to Figure 3 shown, in some embodiments, the first grounding portion 111 is grounded to the first grounding terminal 221 and the second grounding portion 112 is grounded to the second grounding terminal 222, so that the metal carrier plate 110 and the grounding layer 220 form a LOOP mode of the first antenna 121 at the groove 113. In this way, in the LOOP mode, the anti-interference ability of the first antenna 121 is strong.

[0068] When the radiation frequency band of the first antenna 121 of the present disclosure is the WIFI 5G frequency band, in the LOOP mode, compared with the traditional technology, the radiation efficiency of the first antenna 121 is increased by more than 0.8 dB.

[0069] It should be noted that "the power feeding circuit 210 cooperates with the other end of the first antenna 121 for power feeding" includes at least one of coupled power feeding and / or conductive power feeding.

[0070] In one example, the power feeding circuit 210 conducts power feeding with the first antenna 121. In this way, it is beneficial to improve the radiation efficiency of the first antenna 121.

[0071] Combined with any of the above embodiments, as Figure 4 shown, in some embodiments, the first antenna 121 includes a radiation arm 1211, a third grounding portion 1212 grounded to the metal carrier plate 110, and a power feeding portion 1213 that conducts power feeding with the power feeding circuit 210. One end of the radiation arm 1211 is connected to the third grounding portion 1212, and the other end of the radiation arm 1211 is connected to the power feeding portion 1213. The power feeding portion 1213 is spaced from the groove 113 in the second direction. Wherein, the second direction is perpendicular to the first direction. In this way, through the conductive power feeding of the power feeding portion 1213 and the power feeding circuit 210, it is convenient to radiate energy through the radiation arm 1211. At the same time, by using the grounding cooperation of the third grounding portion 1212 and the metal carrier plate 110, it is convenient to adjust the resonance of the first antenna 121 through the grounding cooperation of the metal carrier plate 110 and the grounding layer 220. And the power feeding portion 1213 is spaced from the groove 113 in the second direction. That is, the power feeding portion 1213 is disposed between the first grounding portion 111 and the second grounding portion 112 in the second direction to better excite the radiation arm 1211, improve the radiation efficiency of the first antenna 121, and improve the gain of the first antenna 121 in the horizontal direction.

[0072] Optionally, the power feeding circuit 210 conducts power feeding with the power feeding portion 1213 through a conductive sheet.

[0073] As Figure 4 shown, in some embodiments, a radiation stub 1214 is provided at the other end of the radiation arm 1211. At least part of the radiation stub 1214 protrudes toward the groove 113 and is disposed in the first antenna gap 101. The end of the radiation stub 1214 is provided with the power feeding portion 1213. In this way, the space of the first antenna gap 101 is fully utilized to set the radiation stub 1214, which is convenient to use the radiation stub 1214 to improve the radiation performance of the first antenna 121, and thus can improve the communication performance of the electronic device 1.

[0074] Combined with Figure 3As shown, in some embodiments, the housing assembly 100 further includes a dielectric body 130, and at least a part of the dielectric body 130 is filled in the groove 113. In this way, the first antenna 121, the metal carrier plate 110, the dielectric body 130, and the circuit board 200 form a dielectric resonator antenna, which facilitates the flexible adjustment of the resonance of the first antenna 121 by adjusting the length of the dielectric body 130, and can improve the radiation efficiency of the first antenna 121 without increasing the size of the radiation arm 1211 of the first antenna 121.

[0075] In some embodiments, the dielectric constant of the dielectric body 130 is 3.3 to 3.8. In this way, the dielectric body 130 can be formed by an insulating material, and then the radiation performance of the first antenna 121 can be adjusted through the groove 113 and the dielectric body 130 filled in the groove 113 without changing the assembly process of the housing assembly 100, which is easy to implement and the manufacturing cost of the housing assembly 100 is low.

[0076] Combined with Figure 3 As shown, in some embodiments, the circuit board 200 includes a substrate 230, a feeding circuit 210 and a grounding layer 220 are arranged on the substrate 230, the substrate 230 is fixedly connected to the housing assembly 100, and the dielectric constant of the substrate 230 is 4.0 to 4.4. In this way, the first grounding portion 111 is grounded to the first grounding terminal 221 and the second grounding portion 112 is grounded to the second grounding terminal 222, and the radiation efficiency of the first antenna 121 can also be adjusted by using the substrate 230 of the circuit board 200, further improving the flexibility of the design of the first antenna 121.

[0077] Combined with Figure 3 As shown, in some embodiments, at least a part of the dielectric body 130 is clamped between the circuit board 200 and the metal carrier plate 110. In this way, by cooperating with the metal carrier plate 110 using the dielectric body 130, the circuit board 200 can be better supported, so that the circuit board 200 is reliably fixed on the housing assembly 100, improving the reliability of the electronic device 1.

[0078] It should be noted that there can be various specific implementation manners of the housing assembly 100, including a middle frame assembly, a rear cover assembly, etc. For example, the first antenna 121 is a patch antenna and is fixedly arranged on the rear cover assembly.

[0079] Such as Figures 2 to 4 As shown, in some embodiments, the housing assembly 100 includes a metal frame 120, the first antenna 121 is a frame antenna and is arranged on the metal frame 120, at least a part of the metal carrier plate 110 is arranged inside the metal frame 120, and at least a part of the dielectric body 130 is nested and cooperated with the metal frame 120 and / or the metal carrier plate 110.

[0080] Such as Figure 4As shown, in some embodiments, the metal housing 120 includes a second antenna 122 spaced apart from the first antenna 121 to form a slit 103. At least a portion of the second antenna 122 is spaced apart from the metal carrier plate 110 to form a second antenna slot 102. The slit 103 communicates with the first antenna slot 101 and the second antenna slot 102. At least a portion of the dielectric body 130 is filled in the slit 103, the first antenna slot 101, and the second antenna slot 102. In this way, by filling at least a portion of the dielectric body 130 in the groove 113, the slit 103, the first antenna slot 101, and the second antenna slot 102, it is convenient to realize the fixed connection with the metal carrier plate 110 and the metal housing 120, which can further improve the connection strength between the metal carrier plate 110 and the metal housing 120 and enhance the protection performance of the housing assembly 100.

[0081] Optionally, in some embodiments, the metal housing 120 is fixedly connected to the metal carrier plate 110 and integrally formed by secondary injection molding with the dielectric body 130. In this way, by integrally forming and fixedly connecting the dielectric body 130 with the metal carrier plate 110 and the metal housing 120, the assembly process can be reduced and the assembly efficiency of the housing assembly 100 can be improved.

[0082] In addition, the dielectric body 130 can also be used to form at least one of an insulating mounting area, an insulating connection part, an insulating mounting part, etc. on the housing assembly 100, which can meet the installation of different types of electronic devices.

[0083] In some embodiments, the strength of the metal housing 120 is greater than that of the metal carrier plate 110. In this way, connecting the metal carrier plate 110 with different strengths to the metal housing 120 facilitates using the stronger metal housing 120 as a protective frame. And using the metal carrier plate 110 with lower strength to set the structural features required for carrying devices is easy to manufacture. In this way, the housing assembly 100 has good protection performance and can reduce the manufacturing difficulty and production cost.

[0084] And the electronic device 1 applies the above-mentioned housing assembly 100, so that the electronic device 1 has good protection performance and is beneficial to reducing the production cost of the electronic device 1.

[0085] It should be noted that the metal carrier plate 110 should be understood in a broad sense. And there can be various specific structures of the metal carrier plate 110. For example, at least a portion of the metal carrier plate 110 is plate-shaped to form a carrying structure of the carrying surface.

[0086] Optionally, in some embodiments, the metal carrier plate 110 is provided with a plate body and a connecting plate provided at the edge of the plate body. At least one of the plate body and the connecting plate is provided with a carrying structure.

[0087] In some embodiments, the material of the metal housing 120 and the material of the metal carrier plate 110 are metal materials, and the density of the metal carrier plate 110 is less than the density of the metal housing 120. In this way, the housing assembly 100 can meet the requirement of the thinning of the electronic device 1, which is beneficial to realizing the light weight of the electronic device 1 and facilitating holding and / or carrying.

[0088] In addition, by using the metal characteristics of the metal housing and the metal carrier plate, at least one of a shielding structure, a grounding structure, an antenna structure, etc. can be formed on the housing assembly.
