Referring to fig. 1, the present embodiment provides a mobile terminal 100, where the mobile terminal 100 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. The mobile terminal 100 of the present embodiment is described by taking a mobile phone as an example. The mobile terminal 100 includes an electronic body section 10, and the electronic body section 10 includes a housing 12 and a main display 14 disposed on the housing 12.

In the present embodiment, the main display 14 generally includes the display panel 111, and may include a circuit or the like for responding to a touch operation performed on the display panel 111. The Display panel 111 may be a Liquid Crystal Display (LCD) panel, and in some embodiments, the Display panel 111 may also be the touch screen Display 109.

The housing 12 is used for installing the main display 14 and for accommodating electronic components of the mobile terminal 100, and the specific structural form of the housing 12 is not limited.

The main display 14 is generally covered on a side of the face housing 121, and the rear housing 123 is disposed on a side of the face housing 121 facing away from the main display 14.

Referring to fig. 2, the panel 121 includes a frame 1211 and an installation member 1213. In the present embodiment, the frame 1211 is a substantially rounded rectangular frame, and is used to form a frame of the mobile terminal 100. It should be understood that the bezel of the mobile terminal 100 refers to a side portion of the mobile terminal 100 in the thickness direction, and the bezel forms an external appearance of the mobile terminal 100 together with a rear case (e.g., the rear case 123) and a front side surface (e.g., the main display 14) of the mobile terminal 100. The bezel of the mobile terminal 100 may be an integral structure with the front surface, an integral structure with the rear housing, or a separate bezel, and the specific structure thereof is not limited herein. In the embodiment shown in FIG. 2, the frame 1211 is assembled with the rear housing 123 and the main display 14.

In the present embodiment, the mounting member 1213 is used to mount a printed circuit board (not shown), which may be a main board of the mobile terminal 100. The mounting member 1213 is fitted into the frame 1211, so that the frame 1211 is disposed around the mounting member 1213. When the mounting unit 1213 is mounted in the frame 1211, the mounting unit 1213 is located between the main display 14 and the rear case 123. In some embodiments, the material of the mounting member 1213 may include, but is not limited to, a material including any one or a combination of metals, plastics, resins, and rubbers.

The mobile terminal 100 further includes a USB socket (not shown) disposed in the housing 12 and located between the mounting member 1213 and the rear case 123. The USB cradle is used for plugging a USB plug (not shown) adapted to the mobile terminal 100 to implement data exchange or power input. Specifically, in the present embodiment, the USB socket is disposed on the mounting member 1213 and electrically connected to the printed circuit board.

Further, in order to effectively accommodate the USB socket, the mounting member 1213 is provided with a mounting groove 1214, such that the mounting member 1213 is a slotted structure. The mounting groove 1214 is used for partially receiving the USB socket, so that the USB socket is substantially embedded with the mounting member 1213 when the USB socket is mounted on the mounting member 1213, thereby reducing the thickness of the mounting structure of the USB socket and making the overall thickness of the mobile terminal 100 relatively thin.

Further, in order to reinforce the strength of the mounting member 1213 after the installation groove 1214 is opened, the mounting member 1213 is further provided with a structural reinforcement 30. The structural reinforcement 30 is connected to the mounting member 1213 and covers the mounting groove 1214, and the USB sockets are substantially stacked on the structural reinforcement 30. In the present embodiment, the mounting member 30 is substantially in the form of a plate having a recessed structure, the recessed portion of which protrudes into the mounting groove 1214 and is adapted to the contour of the USB socket, so that the structure reinforcing member 30 can partially accommodate the USB socket while reinforcing the structure of the mounting member 1213, making the thickness of the mounting overall structure of the USB socket relatively thin.

Specifically, referring to fig. 3, the structural reinforcing element 30 includes a main body 32 and a recess 34 formed on the main body 32, the main body 32 is connected to the mounting element 1213, and the recess 34 is received in the mounting groove 1214 and is used for receiving the USB socket.

Further, the structural reinforcement 30 is a metal bracket made of a soft alloy, and is formed through a drawing process such that the drawn structure is relatively thin in thickness and high in structural strength, thereby enabling the thickness of the mounting overall structure of the USB cradle to be relatively thin while reinforcing the structure of the attachment 1213. The material of the structural reinforcement 30 may include any one or combination of the following: stainless steel, phosphor copper, red copper, beryllium copper, nickel copper alloy, etc. It is understood that in some embodiments, the structural reinforcement 30 can be any one of a stainless steel bracket, a phosphor copper bracket, a red copper bracket, a beryllium copper bracket, a nickel copper alloy bracket.

Specifically, in the illustrated embodiment, the recess 34 is bent and recessed relative to the surface of the body 32, and forms a receiving space 340, and the receiving space 340 is used for receiving the USB socket. The recess 34 is formed from the body 32 by a stretching process, that is, the recess 34 and the body 32 are of a stretch-formed integrated structure, so that the material of the recess 34 is thinned due to the fact that the surface area is increased by stretching, the overall strength of the structural reinforcement 30 is enhanced by the stretching bending structure, and the technical bottleneck that the USB socket mounting structure is difficult to be thinned on the premise of considering the structural strength is broken through.

Referring to fig. 4 and 5, in particular, the concave portion 34 includes a stretching surface 341 and a bottom wall 343. The stretching surface 341 is bent from the body 32 and extends along a direction substantially perpendicular to the body 32, the bottom wall 343 is connected to an end of the stretching surface 341 away from the body 32, and the bottom wall 343 and the stretching surface 341 together form the receiving space 340.

Further, in this embodiment, the stretching surface 341 includes a first stretching surface 3411, a second stretching surface 3413, and a third stretching surface 3415, the second stretching surface 3413 is connected to one end of the first stretching surface 3411 and is bent with respect to the first stretching surface 3411, and the second stretching surface 3413 is substantially perpendicular to the first stretching surface 3411; the third stretching surface 3415 is connected to an end of the second stretching surface 3413 remote from the first stretching surface 3411 and is bent with respect to the second stretching surface 3413, and the third stretching surface 3415 is disposed opposite to the first stretching surface 3411. The three sides of the bottom wall 343 are connected to the first stretching surface 3411, the second stretching surface 3413 and the third stretching surface 3415, respectively, and the connecting structure of the bottom wall 343 and the stretching surface 341 makes the receiving space 340 substantially have a groove-shaped space with one end open to fit the contour of the USB socket.

The structural reinforcement 30 is connected to the mounting member 1213 through the body 32, and the connection manner of the body 32 and the mounting member 1213 is not limited. For example, the body 32 and the mounting member 1213 may be connected by a snap connection, a threaded connection, an adhesive connection, and the like, and are not limited to those described in this specification. In some embodiments, the structural reinforcement 30 can be connected to the mounting member 1213 through both the body 32 and the bottom wall 343.

Referring again to fig. 2 and 3, in some embodiments, the body 32 and the mounting member 1213 are connected by a threaded connection. Further, the body 32 and the mounting member 1213 are fastened to the heat-fusible nut 52 by a threaded connection 51. Specifically, in the embodiment shown in fig. 2, the body 32 is provided with a connecting hole 320, and correspondingly, the mounting member 1213 is provided with a receiving hole 1216, and the heat-fusible nut 52 is received in the receiving hole 1216 and is combined with the mounting member 1213 after heat-fusing. The threaded connection member 51 is threaded with the heat-fusible nut 52 after passing through the connection hole 320, so as to connect the body 32 to the heat-fusible nut 52, so that the connection between the structural reinforcement 30 and the mounting member 1213 is more secure and reliable, and the displacement of the structural reinforcement 30 when the mobile terminal 100 is impacted by an external force is avoided. It is understood that the number of the connection holes 320, the accommodation holes 1216, the threaded connectors 51, and the heat-fusible nuts 52 may be one or more, for example, one, two, three, four, … … or more. It is understood that the threaded connection 51 may be, but is not limited to: screws, studs, bolts, etc.

Further, particularly in the embodiment shown in fig. 2 and 3, the body 32 and the mounting member 1213 are connected to each other by a plurality of different sets of threaded connectors and heat-fusible nuts to reinforce the connection structure between the structural reinforcement 30 and the mounting member 1213. The threaded connector 51 comprises a first threaded connector 511 and a second threaded connector 513, the hot-melt nut 52 comprises a first hot-melt nut 521 and a second hot-melt nut 523, the first threaded connector 511 is screwed with the first hot-melt nut 521, and the second threaded connector 513 is screwed with the second hot-melt nut 523. Further, the size of the first threaded connector 511 is smaller than that of the second threaded connector 513, and the size of the first heat-fusible nut 521 is smaller than that of the second heat-fusible nut 523. During assembly, the first threaded connector 511 is connected to the first hot-melt nut 521 after passing through the structural reinforcement 30, so that the reinforcement 30 is primarily fixed to the mounting member 1213, and then the USB socket is mounted on the structural reinforcement 30, and then the second threaded connector 513 sequentially passes through the USB socket and the structural reinforcement 30 and is connected to the second hot-melt nut 523, so that the mounting structure of the USB socket can be further reinforced, and the structural reinforcement 30 and the connection between the USB socket and the mounting member 1213 are firm and reliable.

Further, referring to fig. 4, in the present embodiment, the body 32 includes a first body 325, a second body 326 and a third body 327, the first body 325 is connected to the first stretching surface 3411, the second body 326 is connected to the second stretching surface 3413, and the third body 327 is connected to the third stretching surface 3415. The first body 325, the second body 326 and the third body 327 are arranged in a reverse U shape.

The second body 326 is provided with a first connection hole 3201, the mounting member 1213 is provided with a first accommodation hole 3217 corresponding to the first connection hole 3201, and the first heat-fusible nut 521 is accommodated in the first accommodation hole 1217; the first screw-threaded connecting element 511 is disposed through the first connection hole 3201 and screwed with the first heat-fusible nut 521. The bottom wall 343 is also provided with a first connection hole 3201, the mounting member 1213 is provided with a first receiving hole 3217 corresponding to the first connection hole 3201 of the bottom wall 343, and the bottom wall 343 is connected to the mounting member 1213 by the first threaded connection 511. In this embodiment, the second body 326 is connected to the two first heat-fusible nuts 521 through two first threaded connectors 511, the bottom wall 343 is connected to the mounting member 1213 through one first threaded connector 511 connected to the first heat-fusible nut 521, and the three first threaded connectors 511 are distributed in a substantially "pin" shape, so that when the structural reinforcement member 30 is connected to the mounting member 1213, the fastening force applied to the structural reinforcement member 30 is uniform, and therefore, the structural reinforcement member 30 is connected to the housing 12 with a firm and reliable structure, and is not easily deformed even if the structural reinforcement member 30 is thin.

The first body 325 and the third body 327 are substantially parallel to each other, the first body 325 and the third body 327 are both provided with a second connecting hole 3203, the mounting member 1213 is provided with a second containing hole 1218 corresponding to the second connecting hole 3203, the second heat-fusible nut 523 is contained in the second containing hole 1218, and the second threaded connecting member 513 is inserted through the second connecting hole 3203 and is screwed with the second heat-fusible nut 523. In the present embodiment, the first body 325 and the third body 327 are connected to the mounting member 1213 through a second screw connector 513, so that the fastening force applied to the structural reinforcement 30 and the USB socket when the structural reinforcement 30 and the USB socket are connected to the mounting member 1213 is uniform, and the structure of the structural reinforcement 30 and the USB socket connected to the casing 12 is firm and reliable, and the structural reinforcement 30 is not easily deformed even if the structural reinforcement 30 is thin.

In some embodiments, the second threaded connector 513 is further configured to fix a printed circuit board, and specifically, the USB socket substantially overlaps the structural reinforcement 30, the printed circuit board substantially overlaps the mounting member 1213 and the structural reinforcement 30, and the second threaded connector 513 passes through the printed circuit board and the USB socket in sequence and then is screwed with the second heat-fusible nut 523. Because the specification of the first threaded connector 511 is different from the dimension of the second threaded connector 513, the first threaded connector 511 with a smaller specification is adopted to fix the structural reinforcement 30, and the second threaded connector 513 with a larger specification is adopted to fix the USB socket, the printed circuit board and the structural reinforcement 30, so that the USB socket has stronger structural strength on the premise of ensuring the compact mounting structure of the USB socket.

Further, the structural reinforcement 30 and the mounting member 1213 are connected together by the threaded connection member 51 and the heat-fusible nut 52, so that the problem of positioning deviation of adhesive bonding can be avoided, and the mounting of the structural reinforcement 30 is more accurate. In addition, the connection strength of the threaded connection is relatively high, and when the mobile terminal 100 is impacted by an external force, the structural strength between the structural reinforcement member 30 and the mounting member 1213 is enhanced by the threaded connection, so that the structural reinforcement member 30 is not easily displaced during the impact, the mounting is more secure and reliable, and the structure of the mounting member 1213 is further enhanced.

It will be appreciated that in other embodiments, the structural reinforcement 30 and the attachment members 1213 may be connected by any one or combination of the following means of connection: threaded connector connection, hot melt connection, injection molding connection and adhesive bonding. For example, the structural reinforcement 30 and the attachment 1213 may be connected to each other by a screw connection using an adhesive, thereby improving the reliability of connection while maintaining the sealing performance of the mounting structure of the USB socket.

In the mobile terminal 100 provided in the embodiment of the present application, the mounting member 1213 having a recessed structure is used to mount the USB socket, the USB socket is partially received in the mounting groove 1214, and the USB socket and the mounting member 1213 are substantially nested with each other, so that the overall thickness of the mounting structure of the USB socket is relatively thin. Meanwhile, the structural reinforcement 30 is arranged at the mounting groove 1214 of the mounting member 1213, which can make up for the insufficient strength of the grooving structure of the mounting member 1213, so that the mounting structure of the USB socket has higher structural strength. Further, the structural reinforcement 30 is a soft alloy stretch-formed member, so that the structural reinforcement itself has a relatively thin thickness and a relatively high structural strength, and when the structural reinforcement 30 is mounted on the mounting member 1213, the structural strength of the mounting member 1213 can be effectively reinforced, and the overall thickness of the mounting structure of the USB socket is less affected. As described above, in the mobile terminal 100, the mounting structure of the USB socket is reinforced by the structural reinforcement 30 formed by stretching, so that the overall thickness of the mounting structure can be reduced while the structural strength is high, which is advantageous for the slim design of the mobile terminal 100.

Referring to fig. 6, regarding the mobile terminal 100 provided in the embodiment of the present application, in an actual application scenario, the mobile terminal 100 may be used as an intelligent mobile terminal, such as a smartphone terminal, in which case the electronic body 10 generally further includes one or more processors 102 (only one is shown in the figure), a memory 104, an RF (Radio Frequency) module 106, an audio circuit 110, a sensor, an input module 118, and a power module 122.
