Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

With the rapid development of electronic technology, electronic products are becoming more and more diversified, and at the same time, electronic products are becoming more and more light and thin. This requires that each component in the electronic product is required to be light and thin. The components also include a middle frame used for mounting a display screen, a battery and a circuit board in the electronic product. However, electronic products are sometimes vulnerable to external impacts. Under the stress impact, the part of the middle frame with weak thickness is easy to deform due to extrusion, and the membrane material on the display screen is damaged to form a display white spot. Especially, for a position with a display screen FPC (Flexible Printed Circuit), the thickness of the middle frame is relatively thinner at the position in order to avoid the display screen FPC. This position is more susceptible to deformation by compression.

The embodiment of the disclosure provides a middle frame. FIG. 1 is a diagram illustrating a mid-frame structure according to an exemplary embodiment. As shown in fig. 1, the middle frame 10 includes:

a first surface 20 including a first mounting region and a recess 12 recessed in at least one location of the first mounting region;

a second surface 21, opposite to the first surface, the second surface at least comprising: a second mounting area 11 and a third mounting area 13; wherein: a groove wall of the groove is raised on the second surface and is at least partially located between the second mounting region and the third mounting region.

In the embodiment of the disclosure, the middle frame may be a middle shell applied in the mobile terminal. The mobile terminal can be a mobile phone, a tablet and other terminals. A first mounting area of the middle frame may be used for mounting the display screen 22, a second mounting area may be used for mounting a battery, and a third mounting area may be used for mounting a circuit board.

In the mobile terminal, the weakest point of the middle frame may be located in the second mounting region where the battery 23 is mounted. When the battery is installed, the battery needs to occupy a large space, and meanwhile, the other surface of the middle frame needs to avoid the display screen FPC, so that the thickness of the middle frame at the position where the battery is installed is generally weak.

In the embodiment of the disclosure, the third installation area is generally located at the position of the charging port in the mobile terminal, and when the display screen of the mobile terminal falls off in a vertical posture, if one end of the charging port is firstly in contact with the ground, the second installation area is located above the third installation area. When mobile terminal fell under this kind of condition, mobile terminal charges mouthful one end atress and strikes, causes the mutual force effect of third mounting region to the second mounting region easily, and the third mounting region just can be by extrusion deformation under the mutual extrusion of second mounting region and mobile terminal shell camera one end casing, the weak position of third mounting region to the display screen side is protruding to cause the demonstration white spot.

In the embodiment of the disclosure, the middle frame is recessed to form a groove at least one position of the first mounting area; the recess is located between the second mounting area and the third mounting area. This recess can be used for buffering the third mounting region to the impact force of second mounting region, weakens the second mounting region to the removal of mobile terminal shell camera one end casing to weaken the extrusion of third mounting region and mobile terminal shell to the second mounting region, thereby reduce the risk that the weak department of center thickness received extrusion deformation, and then reduce the display screen because of center atress extrusion deformation causes the probability that the damage appears the demonstration white spot.

In the disclosed embodiment, as shown in fig. 2, the groove is located in the first mounting region of the first surface, and the groove wall 15 of the groove is located between the second mounting region 11 and the third mounting region 13. The second surface has a boss between the second mounting region and the third mounting region. The boss may be located at an area intersection between the second mounting area and the third mounting area. The position of the boss can be at least partially opposite to or the same as the groove, so that the thickness of the middle frame at the position of the groove is increased, and the middle frame has certain connecting strength at the groove.

FIG. 6 is a schematic diagram illustrating structural deformation of a fluted center when impacted by a force, according to an exemplary embodiment. As shown in fig. 6, the groove 12 and the boss 29 may be present opposite on the middle frame. But the position area of the groove on the middle frame is partially overlapped with the position area of the bulge on the middle frame, or the position area of the groove on the middle frame is positioned in the position area of the bulge on the middle frame. When the position area of the groove on the middle frame is partially overlapped with the position area of the protrusion on the middle frame, or the position area of the groove on the middle frame is positioned in the position area of the protrusion on the middle frame, the protrusion can play a role in enhancing the connection strength of the middle frame at the groove.

In the embodiment of the disclosure, the thickness of the middle frame between the first mounting area of the first surface and the second mounting area of the second surface is smaller than the thickness of the middle frame between the first mounting area of the first surface and the third mounting area of the second surface. Because the second mounting area is used for the battery and needs to avoid the display screen FPC, the thickness of the middle frame at the position of the second mounting area is smaller than that at the position of the third mounting area, so that the battery can be mounted conveniently.

In some embodiments, the groove comprises:

In the embodiment of the present disclosure, the first direction may be a direction along a boundary line between the second mounting region and the third mounting region. The first strip-shaped grooves are distributed along the first direction, so that the grooves serve the purpose of buffering acting force between the second mounting area and the third mounting area.

In the embodiment of the present disclosure, the first strip-shaped groove may be an integrally connected groove distributed along the first direction, or may be a non-connected strip-shaped groove having a plurality of discontinuous groove positions in the middle.

In the embodiment of the present disclosure, when the middle frame is impacted by a force, an interaction force is formed between the second mounting region 11 and the third mounting region 13. As shown in fig. 2, a certain stress area 14 is generated at the weak position of the third mounting area 13 under the interaction force.

Fig. 3 is a schematic diagram illustrating a front face of a bezel without a recess in accordance with an exemplary embodiment. As shown in fig. 3, a region 31 of the first surface of the middle frame corresponding to the second mounting region of the second surface is used for mounting a flexible circuit board (FPC) of the display screen.

Fig. 4 is a schematic diagram of a bezel negative structure without grooves, according to an exemplary embodiment. As shown in fig. 4, a region 41 of the second mounting region of the second surface of the middle frame is used for mounting the battery.

FIG. 5 is a schematic diagram illustrating structural deformation of a bezel without grooves when impacted by a force, according to an exemplary embodiment. As shown in fig. 5, when the middle frame is not provided with a groove, when the terminal falls downward, the third mounting region 13 is stressed to generate an interaction force on the second mounting region 11, and a stress region 14 is generated at a weak position of the second mounting region 11, so that the middle frame bends towards the display screen 22 and damages the display screen 22.

As shown in fig. 6, after the middle frame is provided with the groove, when the terminal falls downwards, the interaction force 26 generated by the third installation region under the force impact on the second installation region is buffered by the groove 12, so that the action force can not be transmitted to the weak position of the second installation region, the risk of extrusion deformation of the weak position of the thickness of the middle frame is weakened, and the probability of the display screen that the white spot appears due to damage caused by extrusion deformation of the middle frame under the force is reduced.

FIG. 7 is a diagram illustrating the stress of a bezel without grooves when impacted by a force, according to an exemplary embodiment. As shown in fig. 7, when no groove is formed in the middle frame, the third mounting region is impacted by a force to generate an interaction force on the second mounting region, and the stress generated at the weak position of the second mounting region is 8.2 Mpa. In contrast, FIG. 8 is a graphical illustration of the stress of a fluted center frame when impacted by a force, according to an exemplary embodiment. As shown in fig. 8, when the middle frame is provided with the groove, the third mounting region is impacted by force to generate an interaction force on the second mounting region, and the stress generated at the weak position of the second mounting region is 3.0 Mpa. Therefore, the grooves can effectively weaken the interaction force generated by the third mounting area to the second mounting area due to stress impact.

The first length condition is determined according to the interaction force formed between the components on the second mounting area and the third mounting area when the middle frame is impacted by force, and comprises the following steps:

the first length condition is determined according to a stress area generated by the interaction force when the middle frame is impacted by a force.

In the embodiment of the disclosure, the greater the strength of the middle frame subjected to the force impact, the larger the stress area generated by the interaction force.

In the embodiment of the disclosure, in order to ensure the buffer effect of the groove on the interaction force, the length of the first strip-shaped groove along the first direction is greater than or equal to the length of the stress area, in the first direction, of the stress area generated by the interaction force of the middle frame when the middle frame is impacted by a force. That is, the length of the first stripe-shaped groove in the first direction needs to cover the boundary of the stress region generated by the interaction force, so that the groove can maximally buffer the interaction force between the second mounting region and the third mounting region.

In some embodiments, the groove further comprises:

In the embodiment of the present disclosure, the groove further includes a second strip-shaped groove in addition to the first strip-shaped groove distributed along the first direction. The second strip-shaped grooves are communicated with the first strip-shaped grooves and distributed along a second direction perpendicular to the first direction. In the present disclosure, the second strip-shaped groove and the first strip-shaped groove are mutually matched to better buffer the interaction force between the second mounting area and the third mounting area.

In the embodiment of the present disclosure, the plurality of second stripe grooves may be located in the middle of the first stripe groove and connected to the first stripe groove to be distributed along the second direction, or may be located at the edge of the first stripe groove and connected to the first stripe groove at a predetermined distance from the edge to be distributed along the second direction. The preset distance can be determined according to the distance between each stress point in the stress area and the edge position of the first strip-shaped groove in the first direction. Namely, the positions of the second strip-shaped grooves and the stress points in the stress area are distributed correspondingly in the first direction.

In the embodiment of the present disclosure, the number of the second stripe grooves communicating with the first stripe groove may be plural. Two adjacent second strip-shaped grooves are arranged separately. The second strip-shaped grooves extend into the third mounting area to divide the third mounting area into a plurality of sub-mounting areas. When the third mounting area is stressed and impacted to generate an interaction force on the second mounting area, the second strip-shaped grooves can buffer the action force of the third mounting area on the second mounting area in the third mounting area.

In the embodiment of the present disclosure, the second strip-shaped groove may also extend to the second mounting region, if necessary, to further buffer the acting force of the third mounting region on the second mounting region.

In the disclosed embodiments, each different sub-mounting area may be used to mount a different device or circuit board. For example, a charging circuit board corresponding to charging of a battery is installed in a part of the sub-mounting area, an audio circuit board communicated with a headset is installed in a part of the sub-mounting area, and the like.

In the embodiment of the present disclosure, the number of the second stripe grooves may be three. The three second strip-shaped grooves are distributed on the same side of the first strip-shaped groove. For example, when the first strip-shaped groove is located at the joint position of the second installation area and the third installation area, the second strip-shaped groove is communicated with the first strip-shaped groove and uniformly distributed in the third installation area.

In some embodiments, the length of each second strip-shaped groove along the second direction satisfies a second length condition, where the second length condition is determined according to the stress intensity of a stress position in a stress region generated by the interaction force when the middle frame is impacted by a force.

In the embodiment of the present disclosure, when determining the length of each second stripe groove along the second direction, the length may be determined according to the stress strength of the stress position in the stress region corresponding to the second stripe groove. For example, the stress region includes three points that are easy to generate strong force, which are the first point, the second point, and the third point. When the stress intensity generated by the first position point is greater than that generated by the second position point, the length of the second strip-shaped groove corresponding to the first position point along the second direction is determined, and the length of the second strip-shaped groove corresponding to the force of the second position point along the second direction is greater. So, can effectively cushion the effort of third installation region to the second installation region comprehensively, and then reduce the risk that the weak department of center thickness received extrusion deformation in the second installation region, reduce the display screen because of center atress extrusion deformation causes the probability that the damage appears the demonstration white spot.

In the embodiment of the disclosure, in order to ensure that the groove can play a role in buffering the acting force and ensure the connection strength of the middle frame at the groove, the buffer of the groove to the stress when the middle frame is impacted by the stress is comprehensively considered when the depth of the groove is determined, and the connection strength of the middle frame at the groove is considered. Therefore, the third length condition is determined according to the buffer of the groove to the stress when the middle frame is impacted by the stress and the preset connection strength of the middle frame at the groove.

In the embodiment of the disclosure, in order to ensure that the groove can play a role in buffering an acting force and ensure the connection strength of the middle frame at the groove, it is determined that the depth of the groove is greater than a first proportion of the thickness of the middle frame at the groove position of the middle frame and is less than a second proportion of the thickness of the middle frame at the groove position of the middle frame. The first proportion and the second proportion are both proportions of less than 100%. Wherein the second ratio is greater than the first ratio. For example, the second ratio is 2/3; the first ratio is 1/2, etc. So, through the degree of depth of injecing the recess, realize that the recess plays the cushioning effect to the effort when, have certain joint strength again.

An embodiment of the present disclosure further provides a terminal, which at least includes:

the middle frame in the above embodiments;

the display screen is arranged in the first installation area;

In the embodiment of the disclosure, the terminal may be a mobile terminal such as a mobile phone and a tablet. Wherein, the terminal comprises the middle frame. The display screen is installed in the first installation area of the first surface of the middle frame. And a battery is arranged in the second mounting area of the second surface of the middle frame. And the charging circuit board is arranged in the third mounting area of the second surface of the middle frame. The weakest point of the thickness of the middle frame is in the second mounting region where the battery is mounted. When the third installation region atress is strikeed, when producing the effort to the second installation region, this effort can be cushioned to the recess to reduce the risk that the weak department of center thickness received extrusion deformation, reduce the display screen because of center atress extrusion deformation causes the probability that the display white spot appears in the damage.

The mode is favorable for the battery and the middle frame to be completely adhered together, the battery can play a role in pulling the middle frame when the terminal falls, and the middle frame is prevented from deforming towards the display screen. The fixed position of the gel 28 is between the battery 23 and the center as shown in fig. 6.

In the embodiment of the disclosure, the colloid covers a stress area generated in the second mounting area when the middle frame is stressed and impacted.

In the embodiment of the disclosure, the battery can be fixed on the second mounting area of the middle frame through the glue, so that the battery can play a role in reinforcing the connection strength of the middle frame. When the third mounting area is impacted, the acting force on the second mounting area can be generated. This force creates a stress zone in the second mounting area at the weak point of the middle frame. The weak position of center can produce to warp to the display screen lateral bending under stress, to this in order to strengthen the weak position department structural strength of center, when fixing the battery through the colloid, can cover the stress region with the colloid to accessible battery counteracts the partial effort to the weak squeezing action of center thickness, weakens the center to the deformation strength of display screen direction, thereby reduces the display screen because of center atress extrusion deformation causes the probability that the damage appears the demonstration white spot.
