Fig. 1 is a schematic structural diagram of a terminal according to an embodiment of the present application, and fig. 2 is a schematic cross-sectional diagram of the terminal shown in fig. 1 along a direction a-a'. Referring to fig. 1 and fig. 2 together, the terminal 1 may be various electronic devices, specifically, mobile devices such as a smart phone, a PDA (Personal Digital Assistant or tablet computer), a navigation device, and wearable devices that can be worn on limbs or embedded in clothes, jewelry, accessories, and the like. It will be appreciated that the specific form of the terminal 1 may be other and is not limited thereto. In the embodiment of the present application, which is exemplarily described by taking a smart phone as an example, the terminal 1 may include a housing 10, a display assembly 20, and the like.

The housing 10 is an outer case of the terminal 1 and protects internal electronic components (e.g., the main board 30, a battery, etc.) of the terminal 1. The housing 10 may include a middle frame 11 and a rear cover, wherein the middle frame 11 and the rear cover are connected to the display assembly 20 (e.g., a display panel) and form a receiving cavity for receiving internal electronic components of the terminal 1, including a rear camera and other related electronic components not exposed from the rear cover.

The display assembly 20 may be electrically connected to a camera module, a battery, a processor (CPU), etc., for displaying information, including but not limited to images captured by the camera module. The display assembly 20 includes a display region and a frame region (also referred to as a non-display region), the frame region is disposed outside the display region, for example, on one or more sides of the display region, or around the periphery of the display region. The light-emitting surface of the display area is referred to as the front surface of the display module 20 and the terminal 1, and the rear cover is the rear surface of the terminal 1. In one embodiment, the display assembly 20 may include a cover plate and a display panel, the cover plate covers the display panel to protect the display panel, the cover plate is fixed to the middle frame 11 at the front of the terminal 1, and the middle frame 11 is fixed to the rear cover at the rear of the terminal 1.

The main board 30 is disposed in a cavity formed by the middle frame 11, the rear cover and the display module 20. The main Board 30 is a Circuit Board of the terminal 1, such as a Printed Circuit Board (PCB), on which various electronic components are mounted, and is electrically connected to corresponding camera modules, a battery, a processor, and the like according to an executed function. The main board 30 may be fixedly mounted to the middle frame 11.

As shown in fig. 2 and 3, the middle frame 11 includes a bottom plate 111, a side wall 112 and a top wall 113, the bottom plate 111 and the top wall 113 are disposed at two opposite ends (for example, upper and lower ends shown in fig. 2) of the side wall 112 and are located at the same side (for example, right side shown in fig. 2) of the side wall 113, and the bottom plate 111, the side wall 112 and the top wall 113 form a receiving space. The main board 30 is accommodated in the accommodating space of the middle frame 11, the height H1 of the accommodating space is the distance between the bottom plate 111 and the top wall 113, and the height H1 of the accommodating space is greater than the thickness D1 of the main board 30, for example, the height H1 of the accommodating space is at least greater than or equal to twice the thickness of the main board 30, which can allow the main boards 30 to be stacked. The housing space allows the main board 30 to be inserted obliquely with respect to the bottom plate 111 and housed therein, and allows the main board 30 to be detached from the housing space with respect to the bottom plate 111.

In the process of assembling the main board 30, first, one side edge of the main board 30 is obliquely inserted into the accommodating space of the middle frame 11, then the opposite side of the main board 30 is put down, the main board 30 is parallel to the bottom plate 111, and the middle frame 11 and the main board 30 are fixed by screw locking or clamping and supporting structural elements. That is, the main board 30 may be assembled with the middle frame 11 in an oblique insertion manner, and the main board 30 may be stacked in the accommodating space of the middle frame 11, that is, the accommodating space may be regarded as a stacking space, so as to facilitate increasing the stacking area of the main boards 30. The increased stacking area of the main board 30 may be: in a direction perpendicular to the base plate 111 (e.g. the vertical direction of the scene shown in fig. 2), the area of the front projection of the top wall 113. For example, in some scenarios, the increased motherboard 30 stacking area may be greater than or equal to 68mm²。

In addition, in the assembling process, the side edge of one side of the main board 30 is inserted into the accommodating space of the middle frame 11, so that the main board 30 can be limited to a certain extent, the falling and deviation risks of the main board 30 in the assembling process can be reduced, and the position accuracy of the installation of the main board 30 can be improved.

After the assembly is completed, the main plate 30 and the side wall 112 can be arranged at a distance without contacting with each other, so that the probability of collision between the main plate 30 and the middle frame 11 can be reduced.

In some scenarios, the opposite side of the middle frame 11 may not be provided with the top wall 113, but only the bottom plate 111 and the side wall 112 are provided, so that after one side of the main board 30 is obliquely inserted into the accommodating space of the middle frame 11, the opposite side of the main board 30 is conveniently put down.

In other scenes, the opposite other side of the middle frame 11 may also have the same structure, after the side edge of one side of the main board 30 is obliquely inserted into the accommodating space of the middle frame 11, by pressing the main board 30, the opposite side of the main board 30 presses the top wall 113, so that the top wall 113 contracts toward the side wall 112 after being pressed by the main board 30 and is clamped between the top wall 113 and the bottom plate 111 on the other side, then the top wall 113 recovers deformation, and the opposite side of the main board 30 is clamped into the accommodating space on the other side.

With continued reference to fig. 2 and 3, the bottom plate 111 and the side walls 112 may be parallel and perpendicular to the top wall 113. It should be noted that, limited by the error in actual processing or measurement, the term perpendicular in the present application does not require that the angle between the two be necessarily 90 °, and the term parallel does not require that the angle between the two be 0 °, but rather allows for deviations within a predetermined angular range (e.g., ± 10 °), for example, perpendicular may mean that the angle between any two directions is 80 ° to 100 °, and parallel may mean that the angle between any two directions is 10 ° or less.

In some embodiments, the top wall 113 may be an elastic member, and during the assembling process, the top wall 113 is used for deformation after being pressed by the main board 30, for example, shrinking toward the side wall 112, so that the risk that the top corner O of the top wall 113 presses the main board 30 to damage the main board 30 can be reduced.

Alternatively, the top wall 113 itself is not an elastic member, but a hard structural member (e.g., a metal member) capable of preventing falling, in which case the bottom plate 111, the side walls 112 and the top wall 113 may be an integrally formed structural member, and the embodiment of the present application may provide an elastic member on the top wall 113.

In other embodiments, at least one of the main plate 30 and the top wall 113 is provided with a resilient member on a side facing the other. For example, the main board 30 is provided with an elastic member at a side facing the top wall 113; alternatively, the top wall 113 is provided with an elastic member toward the side of the main board 30; alternatively, the elastic members may be provided on both the side of the main plate 30 facing the top wall 113 and the side of the top wall 113 facing the main plate 30. This elastic component can be rubber piece or rubber pad, sets up in mainboard 30 and the position of roof 113 contact in the assembling process for the extrusion of buffering roof 113 to mainboard 30 reduces the risk that mainboard 30 damaged because of the extrusion.

Of course, the elastic member may be filled and sealed in the accommodating space and located between the main board 30 and the top wall 113, and on the basis of buffering the extrusion of the top wall 113 to the main board 30, the elastic member may also be used to seal the joint between the main board 30 and the middle frame 11, so as to prevent the entry of water, oxygen, dust and other impurities.

The corners of the top wall 113 facing the side of the main plate 30, such as the top corner O shown in fig. 2 and 3, may be rounded, which is also beneficial for reducing the risk of the main plate 30 being damaged due to compression.

In other embodiments, as shown in fig. 2 and fig. 3, the main board 30 may be provided with a blank area 31, the blank area 31 is an area of the main board 30 where no electronic component and no trace are provided, the blank area 31 is at least disposed on a surface of the main board 30 facing the top wall 113, when the main board 30 is inclined with respect to the bottom plate 111 and inserted into the accommodating space of the middle frame 11, along a direction perpendicular to the bottom plate 111, an orthographic projection of the top wall 113 always falls within an orthographic projection of the blank area 31, that is, during the entire oblique insertion assembly process, the top wall 113 cannot contact with other areas (the blank area 31) of the main board 30, so as to prevent the top wall 113 from pressing and damaging the electrical component and the trace mounted on the main board 30, and ensure the normal function of the main board 30.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application, or which are directly or indirectly applied to other related technical fields, are included in the scope of the present application.
