The terminal device comprises:

a middle frame 11, wherein the middle frame 11 is provided with a first surface and a second surface which are oppositely arranged; wherein, the side direction of the middle frame 11 is formed with an antenna radiation structure 111;

side key assembly 12 includes at least: the side key circuit board assembly 121, one end of the side key circuit board assembly 121 is electrically connected with the first surface, and the other end of the side key circuit board assembly 121 is turned towards the second surface.

In an embodiment of the present disclosure, the terminal device includes: a middle frame and side key assembly;

here, the middle frame is used for providing supporting function for components in the terminal equipment, so that the components in the terminal equipment can be mounted together, for example, components such as a camera, a receiver, a battery and the like in the terminal equipment can be mounted on the middle frame for fixing.

The middle frame may be a metal material including, but not limited to, aluminum alloy, magnesium alloy, stainless steel, or the like.

The middle frame is provided with a first surface and a second surface which are oppositely arranged; wherein, the first surface and the second surface can be used for fixing components in terminal equipment.

Here, the first surface may be a top surface of the middle frame, and the second surface may be a bottom surface of the middle frame;

in some embodiments, the terminal device may further include: the middle frame is arranged between the front cover and the rear cover; wherein the first surface is closer to the front cover than the second surface.

It is understood that the front cover of the terminal device refers to the cover plate of the terminal device adjacent to the display screen assembly, and the rear cover of the terminal device refers to the cover plate of the terminal device adjacent to the battery; and the front cover, the rear cover and the middle frame of the terminal equipment form a closed area, and components of the terminal equipment are accommodated in the closed area.

The front cover, the rear cover and the middle frame of the terminal equipment jointly form the appearance surface of the terminal equipment, so that the terminal equipment can be protected against falling on one hand, and the terminal equipment can be decorated on the other hand, so that the terminal equipment is attractive.

The side key assembly is mountable on the center frame and is proximate to an antenna radiating structure of the center frame.

The side key assembly includes at least: and the side key circuit board assembly is arranged on the middle frame and is electrically connected with the middle frame.

In the related art, a penetrating processing mode is generally adopted to mount the side key assembly on the middle frame; for example, as shown in fig. 3, fig. 3 is a schematic view of the installation of a side key circuit board assembly on the second surface of the middle frame shown in the related art. The middle frame reserves a space for assembling the side key circuit board assembly 121, one end of the side key circuit board assembly 121 is fixedly arranged on the second surface of the middle frame, and the side key circuit board assembly 121 is electrically connected with the second surface; the other end of the side key circuit board assembly 121 is folded over to the first surface of the middle frame.

In addition, as shown in fig. 4, fig. 4 is a schematic coupling diagram of a side key circuit board assembly and an antenna radiation structure in a middle frame shown in the related art; since the side key circuit board assembly 121 is close to the antenna radiation structure 111 on the middle frame, the side key circuit board assembly 121 with the metal wire is excited by the antenna radiation structure 111 to generate reverse current, and noise is generated in the radiation frequency band of the antenna radiation structure 111, so that the performance of the antenna radiation structure is reduced.

According to the embodiment of the disclosure, one end of the side key circuit board assembly is fixedly arranged on the first surface of the middle frame, one end of the side key circuit board assembly is electrically connected with the first surface, and the other end of the side key circuit board assembly is folded and fixed on the second surface of the middle frame.

It will be appreciated that the side key circuit board assembly may be a flexible circuit board that is folded over and secured to two opposing surfaces (i.e., a first surface and a second surface) of the center frame.

It should be noted that, compared with the scheme that one end of the side key circuit board assembly is directly electrically connected with the second surface of the middle frame, the other end of the side key circuit board assembly is folded to the first surface of the middle frame, in the embodiment of the disclosure, one end of the side key circuit board assembly is electrically connected with the first surface of the middle frame, the other end of the side key circuit board assembly is folded to the second surface of the middle frame, so that the relative distance between the side key circuit board assembly and the antenna radiation structure can be effectively increased, and the performance influence on the antenna radiation structure is reduced.

Optionally, the middle frame includes:

a carrying plate;

the frame is arranged on the periphery of the bearing plate, one side of the frame bends towards the second surface of the bearing plate, and the frame is at least used for forming the antenna radiation structure.

In an embodiment of the present disclosure, the middle frame may include: a bearing plate and a frame;

the frame is arranged on the periphery of the bearing plate and is fixedly connected with the bearing plate;

illustratively, the frame and the carrier plate are of unitary construction, i.e., the frame and the carrier plate are integrally formed.

The bearing plate is provided with a first surface and a second surface which are oppositely arranged, and the first surface and the second surface of the bearing plate can be used for bearing functional devices in terminal equipment. Here, the first surface may be a top surface and the second surface may be a bottom surface.

The frame extends near one side of the second surface of the bearing plate and is bent towards the second surface of the bearing plate to form a flanging structure; the antenna radiating structure may be a part of a frame, and radiate through the frame to implement communication of the terminal device.

It should be noted that, as shown in fig. 5, fig. 5 is a schematic cross-sectional comparison diagram of a frame with a flanging structure and a conventional frame according to an exemplary embodiment. The reference numeral 5a shows a conventional frame, the reference numeral 5b shows a frame with a flanging structure, and compared with the conventional frame, the cross-sectional area of the frame with the flanging structure is increased by 200%; the radiator area of the antenna radiation structure formed by the antenna radiation structure is also greatly improved, so that the radiation performance of the antenna radiation structure is improved.

For such an antenna radiation structure with a flange structure, if the side key circuit board assembly is mounted on the carrier board in a conventional mounting manner (the mounting manner shown in fig. 3), since the second surface of the carrier board is covered by the (metal) flange structure of the frame, the metal on the second surface of the carrier board at the position for mounting the side key circuit board assembly cannot be completely removed, so that the side key circuit board assembly cannot be mounted on the second surface of the carrier board.

And because of the flanging structure of the antenna radiation structure, the coupling area of the side key circuit board assembly and the antenna radiation structure is increased, and the radiation performance of the antenna radiation structure is affected.

In this embodiment of the present disclosure, since the side key circuit board assembly is electrically connected to the first surface of the middle frame (i.e., the first surface of the carrier plate), even if the second surface of the carrier plate is covered by the frame (i.e., the middle frame having the flange structure), the electrical connection between the side key circuit board assembly and the first surface is not affected, and the installation applicability of the side key circuit board assembly is improved.

The bracket assembly is mountable within the recess structure;

it should be noted that, in order to reduce the occupation of the accommodating space between the middle frame and the front cover by the bracket assembly, a groove structure may be disposed on the first surface of the middle frame, so as to facilitate the installation of the bracket assembly in the groove structure.

It will be appreciated that since the bracket assembly is located between the side key body and the side key circuit board assembly, the location of the groove structure within the bezel may be located between the side key body and the side key circuit board assembly.

It should be noted that, the functional devices in the terminal device are generally grounded; here, grounding refers to the neutral point of the power system and the electrical device, the exposed conductive portion of the electrical equipment, and the device-external conductive portion being connected to the ground via conductors; within the terminal equipment, grounding generally refers to connecting the functional device directly to the ground of the center.

It is understood that by providing at least one grounding portion on the first surface and/or the second surface of the middle frame, the at least one grounding portion may be used to connect with a functional device mounted on the first surface and/or the second surface, so as to conduct out static electricity generated by the functional device, so as to reduce interference of static electricity generated by the functional device on an antenna radiation structure.

And the at least one grounding part and the groove structure on the middle frame form a shielding layer together so as to shield interference of the side key circuit board assembly and the functional device arranged on the middle frame on the antenna radiation structure.

It can be appreciated that the groove structure provided on the middle frame not only can be used for accommodating the bracket component of the side key component, but also can be used for forming a shielding wall by using the side wall of the groove structure, and the influence of the side key circuit board component on the radiation performance of the antenna radiation structure is reduced by the shielding wall.

It will be appreciated that the surface of the display screen assembly facing the center frame is provided with a grounded metal area, as shown in fig. 7, and fig. 7 is a schematic diagram of a partial structure of the first surface of a center frame, as shown in fig. 7, according to an exemplary embodiment. The reference numeral 7a indicates a projection area of the grounding metal area facing the middle frame, and the first grounding portion 113a may be disposed in the projection area, so that the first grounding portion 113a is in fit connection with the grounding metal area of the display screen assembly, and static electricity generated by the display screen assembly is introduced into the first grounding portion through fit connection of the first grounding portion and the grounding metal area, so as to achieve a conductive shielding effect, thereby reducing signal interference.

Optionally, as shown in fig. 6-7, the middle frame 11 has at least one hole 114;

the side key circuit board assembly 121 includes:

the first turnover part is fixed on the first surface of the middle frame 11 and is electrically connected with the middle frame 11;

the connecting portion is located between the first and second turnups, and connects the first and second turnups. It is understood that the first folding portion, the second folding portion and the connecting portion may be an integrally formed structure.

The length of the connecting part is smaller than that of the first turnover part and that of the second turnover part, and the length of the connecting part is smaller than that of the first turnover part and that of the second turnover part, so that the resistance of turnover can be reduced when the side key circuit board assembly is turned over, the side key circuit board assembly is easier to turn over, the turnover time is shortened, and the installation efficiency of the side key circuit board assembly is improved.

The first turnover part is fixed on the first surface of the middle frame, the second turnover part is fixed on the first surface of the middle frame, and the first turnover part is electrically connected with the first surface of the middle frame.

It should be noted that, in the embodiment of the present disclosure, the first turnover portion fixed on the first surface of the middle frame is electrically connected with the middle frame, so that the relative distance between the side key circuit board assembly and the antenna radiation structure can be effectively increased, and the performance influence on the antenna radiation structure is reduced.

In the embodiment of the disclosure, the first surface of the middle frame may be formed with a receiving groove, and the shape of the receiving groove is adapted to the shape of the first turnover part, so that the first turnover part is installed in the receiving groove.

Here, the first surface of the middle frame may be partially recessed to form the accommodating groove, so that the first turnover part is accommodated in the accommodating groove and is flush with the first surface of the middle frame, thereby reducing the occupation of the accommodating space between the middle frame and the front cover of the side key circuit board assembly.

In an embodiment of the present disclosure, the terminal device further includes: a decoupling assembly;

here, the decoupling component may be a decoupling capacitor and/or a decoupling inductor, and the embodiment of the disclosure is not limited thereto.

It should be noted that, although the shielding layer formed by the groove structure, the first grounding portion and/or the second grounding portion can reduce the interference of the side key circuit board assembly on the antenna radiation structure, due to the arrangement position of at least one side key main body in the terminal device, a part of the circuit board assembly corresponding to the side key circuit board assembly exceeds the shielding area corresponding to the shielding layer, that is, the side key circuit board assembly is at least partially located in the antenna area, as shown in fig. 7, the reference numeral 7b shows an antenna area of the terminal device, that is, an area where the antenna radiation structure of the middle frame is located, and the reference numeral 7c shows a shielding area of the terminal device.

Because the distance between the part of the circuit board assembly positioned in the antenna area and the antenna radiation structure in the side key circuit board assembly is too short, the shielding layer cannot effectively shield the interference of the part of the circuit board assembly positioned in the antenna area to the antenna radiation structure.

According to the embodiment of the disclosure, the decoupling assembly is arranged on the side key circuit board assembly, so that clutter generated by part of circuit board assemblies in the antenna area is eliminated by using the decoupling assembly, and the influence of the side key circuit board assembly on the radiation performance of the antenna radiation structure is reduced.
