The assembly mode can protect the LGA and improve the reliability.

However, this brings about a new problem that the whole key module can be assembled to the mobile terminal only in an internally installed (externally installed from the inside of the middle frame) manner due to the skirt of the protection ring, thereby causing the middle frame to have an enlarged slot in the assembly area,

to this end, an embodiment of the present disclosure provides a key module, and fig. 1 is a schematic structural diagram of a key module according to an exemplary embodiment, as shown in fig. 1, the key module 30 includes:

a guard ring 31, comprising: a bent portion 311; the bent portion 311 has a first engaging member 312;

fingerprint button module 32 includes: the second engaging piece 321;

when the fingerprint key module 32 is located in the accommodating space formed by the annular wall of the protection ring 31, the second engaging member 321 engages with the first engaging member 312.

It should be noted that the key module can be applied to any mobile terminal, and the mobile terminal can be: a smart phone, a tablet computer, or a wearable electronic device, etc.

Fig. 1 is a side view of a key module, in which the shaded portion is a fingerprint key module. When the fingerprint key module is assembled, the fingerprint key module is downwards installed in the protective ring from the opening direction of the protective ring.

In the embodiment of the present disclosure, the fingerprint key module may be a functional module integrated with a fingerprint identification function and a power control function; namely: when assembling to mobile terminal on, fingerprint button module both can discern user's fingerprint, accomplish the unblock, can control mobile terminal's opening or closing again.

In some embodiments, the fingerprint key module comprises: fingerprint chip module (LGA) and power control key; the LGA and the power control key are integrated into a whole. The LGA is used for identifying the fingerprint of a user, and the mobile terminal can be unlocked after the fingerprint identification is successful. The power side key can control the opening or closing of the mobile terminal. The power side key may be a power control key on the side of the screen of the mobile terminal, for example, the power control key may be a control key on the side of the screen of the smartphone.

Because the fingerprint chip module is relatively weak in strength, the fingerprint chip module is very easy to lose efficacy after being extruded. Therefore, the fingerprint chip module needs to be protected. In this disclosed embodiment, protect fingerprint chip module in the fingerprint button module through the guard ring.

The guard Ring may be a metal Ring (Ring), which may be fabricated using a MIM process. The MIM process produces the guard ring by injecting a plasticized mixture of metal powder and binder into an annular mold.

An accommodating space is formed in the ring wall of the protection ring, and when the key module is assembled on the mobile terminal, the fingerprint key module is located in the accommodating space.

The guard ring includes: the bending part is provided with a first clamping piece used for clamping the fingerprint key module. As shown in fig. 1, the first engaging piece is positioned on one side in the opening direction of the protection ring. When the fingerprint key module is located in the accommodating space formed by the annular wall of the protection ring, the second clamping piece at the end part of the fingerprint key module is clamped with the first clamping piece of the protection ring. And through the block, can fix fingerprint button module and protection ring.

Fig. 2 is a partial schematic view of a guard ring according to an example embodiment, the guard ring 40, as shown in fig. 2, including: a bent portion 41 and a non-bent portion 42. Wherein the non-bent portion 42 includes: parallel opposing portions. The bent portion 41 includes: an arc portion 411 connected to the non-bent portion 42, and a first engaging member 412 connected to the arc portion 411. The arc-shaped part 411 and the non-bending part 42 form a ring body similar to a track shape; wherein, the ends of the parallel opposite parts of the non-bending part 42 are respectively connected with the arc-shaped parts 411 to form the ring body similar to the racetrack shape.

Here, the protection ring may be formed of the ring body and a first engaging piece 412, wherein the first engaging piece 412 is located on a first side in an opening direction of the ring body. When the fingerprint key module is assembled, the fingerprint key module sinks into the accommodating space of the protection ring from the second side of the ring body to form fixation; the first side and the second side are opposite.

Due to the engagement in the direction perpendicular to the opening of the protection ring (i.e., the engagement in the left-right direction in fig. 2), the width of the key module assembled on the middle frame can be reduced in accordance with the fixing manner by the skirt in the opening direction of the protection ring (i.e., the vertical direction shown in fig. 1).

Fig. 3 is a schematic structural diagram of a key module according to an exemplary embodiment, in which an LGA51 and a power side key are integrated into a key module. As shown in fig. 3, the fingerprint key module further includes: a flexible circuit board (FPC) 52; LGA51 is located on FPC 52. The LGA51 is connected with an FPC52 through a back adhesive, the FPC52 bypasses the bracket 53 to the back of the bracket 53, a steel sheet 54 is further placed between the bracket 53 and the FPC52, and the steel sheet 54 is located on one side of the bracket 53. The bracket 53 may be bonded directly to the back of the LGA51, supported by the steel plate 54. The guard ring 50 is wrapped outside of the LGA 51.

The bracket 53 comprises a limiting hole 531, and the limiting hole 531 is used for limiting the stroke of the key module on the middle frame and reducing the movement of the key module.

The key module further comprises: a key (Switch) 55; the Switch is responsible for the resilience function of the side key, and the Switch is fixed on the FPC52 in a dispensing mode.

As shown in fig. 3, when assembled, the fingerprint key module is installed into the protection ring from the opening direction of the protection ring. Such button module can directly adorn the assembly outward, stretches into the complete machine from mobile terminal's center trompil promptly and assembles inside, and is more convenient in the assembly, also more makes things convenient for subsequent maintenance to handle.

Next, the corresponding engaging condition when the fingerprint key module is located in the accommodating space formed by the ring wall of the protection ring is described with reference to fig. 2 to 6:

exemplarily, fig. 4 is a partial schematic view of a key module according to an exemplary embodiment, where the fingerprint key module includes:

a fingerprint chip module (LGA)51 engaged with the first engaging portion 413;

and a bracket 53 located at one side of the fingerprint chip module 51 and engaged with the second engaging portion 414.

Here, the first engaging portion 413 and the second engaging portion 414 are located at different positions of the first engaging member.

As shown in fig. 4, the fingerprint key module 51 is located in the accommodating space formed by the ring wall of the protection ring 50, the support 53 is located below the LGA51, and the LGA51 and the support 53 are respectively engaged with different portions of the first engaging member on the protection ring 50.

Here, the first engaging portion and the second engaging portion are connected; as shown in fig. 4, when the fingerprint key module is located in the accommodating space formed by the ring wall of the protection ring, the LGA in the fingerprint key module is located in the ring body formed by the protection ring, the LGA is engaged with the first engaging portion at the end, and the bracket in the fingerprint key module is engaged with the second engaging portion.

Thus, because the fingerprint key module includes: fingerprint chip module and two parts of support, and two parts are located different position region, and through set up corresponding block region on the guard ring, can carry out the block to these two parts in the fingerprint button module more conveniently, and the effect is better on fixing.

In some embodiments, as shown in fig. 2, the first catch 412 includes: a first engaging portion 413 and a second engaging portion 414 connected to the first engaging portion 413.

Here, the first engaging member in the present disclosure includes two engaging portions located at different positions, and the two engaging portions are respectively used for engaging with components at different positions on the fingerprint key module.

In some embodiments, as shown in fig. 2, the second engaging portion 414 includes:

a first engagement space in a step shape;

the bracket is clamped in the first clamping space.

As shown in fig. 2, the first engagement space having a step shape may be formed by a plurality of first engagement surfaces 415, and the first engagement surfaces 415 may be rectangular surfaces. After the first matching surfaces form the first clamping space, the bracket is positioned in the first clamping space.

Here, the engaging space may be concave; or may be a composite space containing both concave and convex shapes. However, when the engaging space is concave, the holder portion engaged with the engaging space needs to be convex to form engagement. Correspondingly, when the engagement space comprises both a concave and a convex shape, the part of the holder cooperating with the engagement space corresponds to the male and the female part. Of course, other configurations capable of engaging may be used, and the formation of the second engaging portion is not limited in the present disclosure.

In some embodiments, since the plurality of first mating surfaces 415 form a step-shaped first engaging space, the plurality of first mating surfaces 415 may include: three of the first mating surfaces 415 that are perpendicular to each other. As shown in fig. 2, three mutually perpendicular first mating surfaces form a right-angled or stepped first engaging space.

In some embodiments, the stepped first engaging space constitutes a groove;

Here, when the three mutually perpendicular first mating surfaces form a right-angled or stepped first engaging space, the production and manufacture are more convenient because of the regular shape.

Other shapes are of course possible, for example, a plurality of said first mating surfaces may also be a plurality of first mating surfaces angled with respect to each other, forming a cone. Illustratively, when the number of the first mating surfaces is 3, the 3 first mating surfaces are at an angle of 120 degrees with respect to each other, so that the first engaging space is in a shape of a recessed cone. Correspondingly, the end of the bracket clamped in the first clamping space is a convex cone.

In some embodiments, as shown in fig. 4, the first engagement space with a step shape faces the first mating surface 61 of the bracket, and a first gap is formed between the first engagement space and the end 531 of the bracket.

Here, the first gap may be determined according to the size of the bracket, the size of the bezel of the mobile terminal, and the thickness of the flexible circuit board (FPC), and for example, the first gap may be 0.08 mm.

Because FPC is arranged between the support and the fingerprint chip module, in order to prevent the support from being scratched by the FPC when the support is clamped with the second clamping part, a first gap is arranged between a first matching surface facing the support and the end part of the support in the plurality of first matching surfaces.

In some embodiments, as shown in fig. 4, the flexible circuit board (FPC) includes:

a first circuit board part 521 located between the fingerprint chip module 51 and the bracket 53 and electrically connected to the fingerprint chip module 51;

and a second circuit board portion 522 connected to the first circuit board portion 521, wherein the second circuit board portion 522 is located between the bracket 53 and the first engaging member and passes through the first slit.

Referring to fig. 2, the FPC is meandering around the support 53 as shown in fig. 2.

The first circuit board section 521 and the second circuit board section 522 are different parts belonging to the same FPC, and the flexible circuit board can be folded.

Here, the width of the first slit is greater than or equal to the thickness of the FPC, so that the FPC is not damaged by being pressed when the holder is engaged with the second engaging portion in assembly.

The first engaging portion will be explained below:

in some embodiments, as shown in fig. 2, the bending portion 41 includes:

the annular wall is bent and is vertically connected to the first engaging member 412 in the opening direction of the protection ring.

Here, the first engaging member is located on a first side in the opening direction of the ring body, and the first engaging member is located on a lower side of the ring body as shown in fig. 2.

When the button module is positioned in the mobile terminal, the button module is positioned at the position of the power side key and is parallel to the plane where the screen is positioned, so that when the bent annular wall is vertically connected with the first clamping piece in the opening direction of the protection ring, the module formed by fusing the fingerprint chip module and the power side key is more regular, and the regular shape of the power side key is more convenient in design and manufacture.

In some embodiments, the first engaging portion includes:

and the second matching surface is vertically connected with the annular wall.

A second clamping space is formed between the annular wall and the second matching surface;

the fingerprint chip module is clamped in the second clamping space.

As shown in fig. 3, the second engagement surface is an engagement surface of the first engaging portion 413, which is in contact with the annular wall. The second mating surface faces the opening direction of the protection ring.

Because the second matching surface is vertically connected with the ring wall, a second clamping space is formed between the second matching surface and the ring wall, and the fingerprint key module is downwards arranged in the protective ring from the opening direction of the protective ring, so that the fingerprint chip module in the fingerprint key module can be exactly positioned in the second clamping space during clamping, and the fingerprint chip module is fixed.

Here, the shape of the fingerprint chip module is the same as the shape of the accommodating space formed by the ring wall of the protection ring, so that more fitting fixation can be realized.

In some embodiments, when the fingerprint chip module is clamped in the second clamping space, a second gap is formed between the fingerprint chip module and the second matching surface.

In the embodiment of the disclosure, in order to prevent the stress of the fingerprint chip module body, the fingerprint chip module can be clamped in the second clamping space, and a second gap is arranged between the fingerprint chip module and the second matching surface.

The width of the second gap may be determined according to the size of the fingerprint chip module, the size of the protection ring, and the size of the middle frame, for example, the width of the second gap may be set to be between 0 and 0.05mm, and for example, the width of the second gap may be 0.03mm, in consideration of the thickness of the frame of the mobile terminal.

The present disclosure further provides a schematic cross-sectional view of a key module, as shown in fig. 5, when the fingerprint key module is installed in the protection ring from the opening direction of the protection ring, the ring wall of the protection ring 70 surrounds the fingerprint chip module 71. Moreover, when assembling, the support part of the fingerprint key module can penetrate through the protection ring 70 and is positioned at the lower side of the protection ring 70, and then when reaching the corresponding clamping position, the fingerprint chip module can be clamped with the first clamping part; the bracket is clamped with the second clamping part.

In some embodiments, the stent comprises:

Here, the stent is a three-dimensional structure including: a first stent surface, a second stent surface and a third stent surface; the first support surface is parallel to the second support surface, and the third support surface is perpendicular to the first support surface and the second support surface. And, first support face is the face nearest apart from fingerprint chip module, first support face towards the protection ring.

The first support surface is provided with a dispensing groove, the second support surface is provided with a positioning column, and the third support surface is provided with a limiting hole penetrating through the third support surface.

The glue dispensing groove is used for containing glue, and the flexible circuit board can be fixed on the support through the glue when the flexible circuit board surrounds the support. The positioning column is used for positioning and fixing the flexible circuit board. The limiting hole is used for allowing a positioning steel sheet to penetrate through, so that the key module is fixed on the middle frame based on the positioning steel sheet.

Here, in order to make the assembly easier, or to achieve the correct position assembly without distinguishing the left and right sides (i.e. the fool-proof design can be performed in the embodiment of the present disclosure), the dispensing slots, the positioning posts, and the limiting holes may be symmetrically distributed on the bracket.

As shown in fig. 6, fig. 6 is a schematic structural diagram of a support in a fingerprint key module according to an exemplary embodiment. In fig. 6, the dispensing slot, the positioning post and the limiting hole are symmetrically distributed on the bracket. Namely, the bracket 80 may include thereon: two spacing holes 81, two glue dispensing grooves 83 and two positioning columns 86, and two spacing holes 81, two glue dispensing grooves 83 and two positioning columns 86 are distributed on the support symmetrically, spacing hole 81 is used for spacing the stroke of the key module on the middle frame, and the movement of the key module is reduced.

When the bracket 80 includes two position-limiting holes, the bracket portion 82 of the bracket between the two position-limiting holes, which faces away from the LGA, may be a supporting position of a key (Switch), i.e., a position where the Switch is disposed.

A dispensing groove 83 is formed in the first bracket surface of the bracket for mounting the Switch, and the dispensing groove 83 may be located on the first bracket surface of the bracket facing the limiting hole 81. The glue dispensing groove 83 is used for placing glue, and the flexible circuit board can be fixed on the bracket 80 by the glue when the flexible circuit board surrounds the bracket 80. Here, because glue is directly placed in the side surface groove of the support to realize the relative fixation of the flexible circuit board and the support, compared with a mode of arranging an adhesive layer between the flexible circuit board and the support, the width of the key module assembled on the middle frame can be further reduced.

When the bracket is engaged with the second engaging portion, the end portion 84 of the bracket is located in the first engaging space. Thus, when the second engaging portion includes three first engaging surfaces perpendicular to each other, and the three first engaging surfaces are perpendicular to each other, the end portion of the bracket engaged with the first engaging space may be a step shape having a right angle.

And, the bracket is formed vertically at the end portion, and may be formed in an arc shape or an inclined surface at a corner position 85 where the end portion contacts the flexible circuit board, so that the possibility of cutting the flexible circuit board at the corner position 85 can be reduced as much as possible.

The bracket 80 further includes: a second support surface; and a positioning column 86 is arranged on the second support surface, and the positioning column 86 is used for positioning and fixing the flexible circuit board. Thus, when the flexible circuit board surrounds the support 80, the flexible circuit board is fixed on the first support surface through glue in the glue dispensing groove 83, and the flexible circuit board is fixed on the second support surface through the positioning column.

In some embodiments, the bracket is partially located within the protective ring;

Here, the height of the ring wall of the protection ring is greater than the height of the fingerprint key module, and when the fingerprint key module is installed in the protection ring from the opening direction of the protection ring downwards, a part of the support is located in the protection ring. When part of the support is positioned in the protective ring, one part of the limiting hole penetrating through the third support surface of the support is positioned in the protective ring (namely, is shielded by the protective ring), and the other part of the limiting hole is exposed outside the protective ring.

When the key module is assembled on the middle frame of the mobile terminal, the key module can be fixed on the middle frame by means of the matching of the second part of the hole diameter which is exposed out of the protection ring and the positioning steel sheet.

Here, the positioning steel sheet includes: the first end is inserted into the second part hole, and the second end is inserted between the positioning column and the middle frame. And the distance between the first end and the second end is larger than the caliber of an opening of a middle frame for installing the key module, so that the key module can be fixed on the middle frame through the positioning steel sheet.

In some embodiments, the side of the protection ring farthest from the support has an inward protrusion, and the protrusion is used for fixing the position of the fingerprint chip module.

Here, the guard ring includes: when the fingerprint key module is downwards installed into the protective ring from the opening direction of the protective ring, an inward bulge can be arranged on the side, farthest from the support, of the protective ring, and the position of the fingerprint chip module is fixed through the bulge. The presence of the raised annular wall allows better fixing of the other positions with respect to a smooth annular wall, due to the increased friction.

So, the button module that this disclosed embodiment provided includes: protection ring and fingerprint key module; the first clamping piece is arranged on the bending part of the protection ring, when the fingerprint key module is located in the containing space formed by the ring wall of the protection ring, the connection and fixation of the protection ring and the fingerprint key module can be realized through the clamping of the first clamping piece and the second clamping piece, and the first clamping piece and the second clamping piece are used for clamping to realize fixation, so that the disassembly is more convenient, and the stacking efficiency can be effectively improved.
