[0017] The accompanying drawings herein are incorporated into the specification and constitute a part of the specification, showing embodiments consistent with the present disclosure and used together with the specification to explain the principles of the present disclosure.

[0021] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] In the related art, the coaxial line of a mobile phone is usually fixed by the wire groove and boss on the middle frame of the mobile phone. Due to the high requirements for mobile phone signals, the coaxial line needs to increase the grounding requirements with the middle frame of the mobile phone. It is difficult to ensure the stability of grounding by simply relying on the contact between the coaxial line and the middle frame. Therefore, a grounding ring is provided on the signal transmission line, and a grounding slot is provided on the middle frame. By clamping the grounding ring in the grounding slot, the signal transmission line can be connected to the middle frame, thereby achieving grounding of the signal transmission line.

[0023] However, it is difficult to effectively fix the coaxial line simply by relying on the wire groove and the boss, and the coaxial line is prone to detach from the groove. In addition, since the grounding ring is usually an ordinary cylindrical rigid grounding ring, it has hard interference contact with the grounding slot. If the middle frame coaxial line groove is made wide, it is easy to cause unstable contact. If the middle frame coaxial line groove is made narrow, the coaxial line grounding ring is not easy to be removed during disassembly.

[0024] In order to solve the above technical problems, according to the embodiments of the present disclosure, a bracket, a middle frame assembly and an electronic device are provided, the bracket comprising: a main body, the main body is provided with a receiving groove for accommodating a wire, the receiving groove comprises a first surface; a conductive member, the conductive member is arranged on the main body, the conductive member comprises a first part, a second part and a first connecting part, the first part is arranged on the first surface and abuts against the wire, the second part is arranged on the main body and abuts against the metal part of the middle frame that fixes the wire, and the first part and the second part are connected by the first connecting part.

[0025] The present invention provides a receiving groove for receiving the wire on the bracket body, so that the bracket itself can improve the fixing effect of the wire, and connects the wire to the first part provided on the first surface of the receiving groove, so that the wire can be connected to the ground through the first part, the first connecting part and the second part in sequence, thereby realizing the grounding setting of the wire, so that the external interference signal to the wire can be introduced into the ground in time, thereby reducing the influence of the external interference signal on the wire.

[0026] It can be understood that the bracket involved in the present disclosure can be applicable to any terminal listed below.

[0027] It can be understood that the terminal involved in the present disclosure, which can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users.

Figure 2 It is a cross-sectional view of a middle frame assembly shown according to an exemplary embodiment. Figure 3 It is a schematic structural diagram of a conductive member shown according to an exemplary embodiment.

[0029] In some embodiments, as Figures 1-3 shown, the bracket may include: a body 100 and a conductive member 110.

[0030] The body 100, and the body 100 can be the basic frame structure of the bracket. The conductive member 110 can be a component with conductivity. Exemplarily, the conductive member 110 can be a metal part.

[0031] The body 100 can be provided with a receiving groove 101 for receiving the wire 200. Exemplarily, the receiving groove 101 can be a recessed structure provided on the body 100. The receiving groove 101 can include a first surface 1001, and the first surface 1001 can be a wall surface inside the receiving groove 101. Exemplarily, the first surface 1001 can be a side wall surface of the receiving groove 101.

[0032] At least a part of the conductive member 110 can be disposed in the body 100. The conductive member 110 can include a first part 111, a second part 112, and a first connecting part 121. The first part 111 can be disposed on the first surface 1001 of the receiving groove 101 and abut against the wire 200. The second part 112 can be disposed on the surface of the body 100 and abut against the metal part 301 of the middle frame 300. And the first connecting part 121 can connect the first part 111 and the second part 112. The wire 200 can be connected to the metal part 301 of the middle frame 300 through the first part 111, the first connecting part 121, and the second part 112 in sequence, so that the external interference signals received by the wire 200 can be timely introduced into the metal part 301 of the middle frame 300 as the ground.

[0033] By connecting the wire 200, the first part 111, the second part 112, and the metal part 301 as the ground in sequence, the grounding setting of the wire 200 is realized, so that the external interference signals received by the wire 200 can be timely introduced into the ground. And by disposing the wire 200 in the receiving groove 101 of the bracket, the effective fixation of the wire 200 is realized.

[0034] In some embodiments, as Figures 1-3 shown, the receiving groove 101 can include a second surface 1002 different from the first surface 1001. The second surface 1002 can be, for example, a wall surface of the receiving groove 101 different from the first surface 1001. Exemplarily, the second surface 1002 can be a side wall surface of the receiving groove 101.

[0035] The conductive member 110 can further include a third part 113 and a second connecting part 122. The third part 113 can be disposed on the second surface 1002 and abut against the wire 200.

[0036] One end of the second connecting part 122 is connected to the third part 113, and the other end of the second connecting part 122 is connected to the second part 112. The wire 200 can be connected to the metal part 301 of the middle frame 300 through the first part 111, the first connecting part 121, and the second part 112 in sequence, so that the external interference signals received by the wire 200 can be timely introduced into the metal part 301 of the middle frame 300 as the ground.

[0037] By providing the third part 113 on the basis of the first part 111, and the third part 113 can be connected to the metal part 301 of the middle frame 300 through the second connecting part 122. Furthermore, the wire 200 can be grounded not only through the first part 111 but also through the third part 113, thus improving the grounding effect of the wire 200 and enabling the external interference signals received by the wire 200 to be timely introduced into the ground.

[0038] In some embodiments, the first part 111 and the third part 113 can be sheet-like components, which can increase the contact area between the first part 111 and the third part 113 and the wire 200, improve the contact stability between the first part 111 and the third part 113 and the wire 200, thereby enhancing the grounding effect of the wire 200, enabling the external interference signals received by the wire 200 to be promptly conducted to the ground.

[0039] In some embodiments, the second part 112 can be a sheet-like component, which can increase the contact area between the second part 112 and the wire 200, improve the contact stability between the second part 112 and the ground, thereby enhancing the grounding effect of the wire 200, enabling the external interference signals received by the wire 200 to be promptly conducted to the ground.

[0040] In some embodiments, as Figures 1-3 shown, the first surface 1001 and the second surface 1002 can be opposite surfaces, so that the first part 111 and the second part 112 can respectively abut against the wire 200 from both sides of the wire 200, and by arranging the first part 111 and the third part 113 on opposite surfaces of the receiving groove 101, the first part 111 and the third part 113 can abut against a plurality of wires 200. Exemplarily, a plurality of wires 200 can be arranged in the first direction, and the first surface 1001 and the second surface 1002 can be in a direction perpendicular to the first direction, so that both the first surface 1001 and the second surface 1002 can contact a plurality of wires 200, thereby enabling multiple wires 200 to be grounded through the first part 111 and the second part 112, thereby enhancing the grounding effect of the wire 200, enabling the external interference signals received by the wire 200 to be promptly conducted to the ground.

[0041] Exemplarily, the wire 200 can include a first wire 201 and a second wire 202. The first wire 201 and the second wire 202 can be arranged in the thickness direction of the middle frame 300. The first part 111 and the second part 112 can be arranged on both sides of the first wire 201 and the second wire 202 in the width direction of the middle frame 300 and abut against the first wire 201 and the second wire 202.

[0042] In some embodiments, as Figures 1-3 shown, the main body 100 can be provided with a first buckle portion 102, and the bracket can be detachably connected to the middle frame 300 through the first buckle portion 102. By providing the first buckle portion 102 detachably connected to the middle frame 300, the fixing effect between the bracket and the middle frame 300 is strengthened, thereby enhancing the effect of the bracket on the wire 200, reducing the situation of the wire 200 falling off, and the buckle structure is convenient for installation and disassembly operations, which is beneficial to product assembly and later maintenance work.

[0043] Exemplarily, the first buckle portion 102 may be a protruding structure provided on the body 100.

[0044] In some embodiments, as Figures 1-3 shown, the conductive member 110 may include a support portion 130. At least a part of the support portion 130 may be disposed within the first buckle portion 102. Among them, the rigidity of the support portion 130 is greater than that of the body 100. By disposing the support portion 130 with greater structural strength within the first buckle portion 102, the support portion 130 can serve as a skeleton structure to provide support for the first buckle portion 102, thereby enhancing the structural strength of the first buckle portion 102, reducing damage to the first buckle portion 102 during the installation and disassembly processes, and further enhancing the durability of the bracket.

[0045] In some embodiments, the conductive member 110 may be a metal member. The metal member has good electrical conductivity and structural strength, so that while ensuring the grounding effect of the wire 200, the structural strength of the first buckle portion 102 can also be enhanced, thereby enhancing the durability of the bracket.

[0046] In some embodiments, as Figures 1-3 shown, the body 100 is a plastic part. The first connection portion 121 and the support portion 130 are provided with through holes 140. At least a part of the body 100 may be disposed within the through holes 140. During the production process of the body 100, the plastic can pass through the through holes 140 and connect the plastics on both sides of the conductive member 110, thereby improving the reliability of the connection between the conductive member 110 and the plastic, reducing the situation of the overall or partial separation and deformation of the conductive member 110 and the plastic during injection molding, resulting in poor flatness, and enhancing the product stability.

[0047] In some embodiments, as Figures 1-3 shown, the receiving groove 101 may be in interference fit with the wire 200. By making the wire 200 in interference fit with the receiving groove 101, the surface of the wire 200 can be tightly connected to the conductive member 110 in the receiving groove 101, thereby enhancing the connection stability between the wire 200 and the conductive member 110, enhancing the grounding effect of the wire 200, and enabling the external interference signals received by the wire 200 to be timely introduced to the ground.

[0048] In some embodiments, the interference amount between the receiving groove 101 and the wire 200 is 0.01 mm to 0.03 mm. By designing the interference amount within the above range, while the wire 200 does not emit deformations that affect performance, it can be in interference fit with the receiving groove 101, enhancing the grounding effect of the wire 200, and enabling the external interference signals received by the wire 200 to be timely introduced to the ground.

[0049] In some embodiments, the conductive member 110 may be a metal member, and the thickness of the conductive member 110 may be 0.02 mm to 0.03 mm. By setting the thickness of the conductive member 110 within the above range, while reducing the weight of the bracket, the electrical conductivity and structural strength of the conductive member 110 can be ensured.

[0050] Based on the same concept, an embodiment of the present disclosure also provides a middle frame assembly.

[0051] In some embodiments, as Figure 1 and Figure 2 shown, the middle frame assembly may include: a middle frame 300 and a bracket. At least a part of the middle frame 300 is a metal part 301, wherein the metal part 301 abuts against the second part 112 of the bracket.

[0052] The middle frame 300 may be provided with a wire groove, and the wire groove may include a mounting groove 303. The wire groove may be used for mounting the wire 200, and the mounting groove 303 may be used for mounting the bracket and the wire 200, so that the bracket can fix the wire 200 to be mounted on the middle frame 300.

[0053] In the present disclosure, by connecting the wire 200 to the first part 111, the second part 112, and the metal part 301 serving as the ground in sequence, the grounding setting of the wire 200 is realized, so that the external interference signals received by the wire 200 can be timely introduced into the ground, thereby reducing the influence of the external interference signals on the wire 200, and by arranging the wire 200 in the receiving groove 101 of the bracket, the effective fixation of the wire 200 is realized.

[0054] In some embodiments, as Figure 1 and Figure 2 shown, the bracket may be in interference fit with the mounting groove 303. By connecting the bracket with the receiving groove 101 in interference fit, the second part 112 of the bracket can be tightly connected to the metal part 301 serving as the ground, thereby improving the connection stability between the conductive member 110 and the metal part 301, thereby improving the grounding effect of the wire 200, so that the external interference signals received by the wire 200 can be timely introduced into the ground.

[0055] In some embodiments, the interference amount between the mounting groove 303 and the bracket is 0.01 mm to 0.03 mm. By designing the interference amount within the above range, while not damaging the bracket, it can be in interference fit with the mounting groove 303, improving the grounding effect of the wire 200, so that the external interference signals received by the wire 200 can be timely introduced into the ground.

[0056] In some embodiments, as Figure 1 and Figure 2As shown, at least another part of the middle frame 300 can be a plastic part 302. The plastic part 302 is provided with a second buckle part 304. The middle frame 300 is buckled and connected to the first buckle part 102 of the bracket through the second buckle part 304. By providing the second buckle part 304 detachably connected to the first buckle part 102, the fixing effect between the bracket and the middle frame 300 is strengthened, thereby improving the effect of the bracket on the wire 200, reducing the situation of the wire 200 falling off, and the buckle structure is convenient for installation and disassembly operations, which is beneficial to product assembly and later maintenance work.

[0057] Exemplarily, the second buckle part 304 can be a groove or a hole that cooperates with the first buckle part 102. When the bracket and the middle frame 300 are assembled, the first buckle part 102 will be embedded into the second buckle part 304 serving as a slot or hole, realizing the fixation of the position of the bracket in space. At the same time, when disassembly is required, the bracket can be taken out by simply pressing the second buckle part 304, which facilitates the subsequent disassembly and maintenance of the product.

[0058] In some embodiments, as Figure 1 and Figure 2 shown, the opening directions of the receiving groove 101 and the mounting groove 303 are different, so that when the bracket is installed in the mounting groove, the opening of the receiving groove 101 can be blocked by the middle frame 300, and the bracket itself can block the opening of the mounting groove 303, thereby improving the fixing effect of the bracket on the wire 200, reducing the situation of the wire 200 falling off from the wire slot, and improving the reliability of the middle frame assembly.

[0059] Based on the same concept, the embodiments of the present disclosure also provide an electronic device.

[0060] Among them, the electronic device can be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, and wearable devices such as watches and bracelets, etc., and can be any electronic device with a bracket. In the following description, a mobile phone is taken as an example for illustration, but the present disclosure is not limited thereto.

[0061] In some embodiments, the electronic device can include a bracket or a middle frame assembly.

[0062] In some embodiments, the electronic device can include a main board and an antenna small board. The wire 200 can be a coaxial cable. One end of the wire 200 is connected to the main board, and the other end of the wire 200 is connected to the antenna small board. The main board can transmit signal data to the antenna small board through the wire 200 so that the electronic device can perform signal radiation.

[0063] The present disclosure realizes the grounding setting of the wire 200 by connecting the wire 200 to the first part 111, the second part 112, and the ground in sequence, so that the external interference signals received by the wire 200 can be timely introduced into the ground, thereby reducing the influence of the external interference signals on the wire 200, and by arranging the wire 200 in the receiving groove 101 of the bracket, the effective fixation of the wire 200 is realized.

[0064] This solution ensures the stability of the coaxial cable grounding effect and at the same time prevents the coaxial cable from detaching from the wire groove; in addition, when assembling the electronic device, by arranging the bracket in the installation groove 303 of the middle frame 300, the protruding first buckle portion 102 of the bracket is embedded into the second buckle portion 304 of the middle frame 300, making the assembly and disassembly process of the coaxial cable simple and easy to operate.
