Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a fingerprint recognition and function key two-in-one module and a terminal. Background Art

[0002] The fingerprint module and the functional side button (such as the power side button) are generally two different functional buttons that exist separately. The fingerprint module is responsible for the fingerprint unlocking and recognition function, and the power side button is responsible for the power on and off function. They each have their own functions and are unrelated to each other; however, this will lead to the situation where there are too many side buttons on the terminal, affecting the effect of industrial design (ID).

[0003] After improvement, the combination of the fingerprint recognition device and the power side button has been realized, for example, an electronic device disclosed in Patent No. CN110262626A: by adding two containing structures on both sides of the fingerprint recognition device, and then using retaining walls to fix the containing structures.

[0004] However, this structure has the following defects: the space requirement around the fingerprint module is relatively large, and because one end of the retaining wall occupies the inner space of the middle frame, the middle frame needs to be provided with a receiving groove corresponding to the end of the retaining wall. The part of the middle frame corresponding to the receiving groove is thinner than other positions, resulting in lower strength of the middle frame in this area. Summary of the invention

[0005] The purpose of the present invention is to provide a fingerprint recognition and function key two-in-one module to solve the problem that the fingerprint recognition module and the power supply on the existing electronic device are two-in-one, resulting in a large space requirement around the fingerprint module and low middle frame strength.

[0011] The fixed bracket is arranged on one side of the fingerprint recognition device along the Z-axis direction. The fingerprint recognition device is provided with a limiting hole, and the fixed bracket is provided with a positioning bone extending into the limiting hole, which can limit the sliding path of the fingerprint recognition, while saving space at both ends of the fingerprint recognition device and avoiding grooves in the shell at both ends of the corresponding fingerprint recognition module, thereby improving the strength of the shell.

[0020] The fixing bracket is provided with a positioning hole corresponding to the positioning column.

[0021] The positioning column and the positioning hole cooperate with each other to provide guidance when the fixing bracket is installed on the shell.

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0048] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] The present invention provides a fingerprint recognition and function key two-in-one module and a terminal equipped with the module, and the terminal can be any possible device equipped with a side fingerprint recognition device, such as a mobile phone, a tablet computer, a watch or other wearable electronic device. In this embodiment, the terminal is a mobile phone.

[0052] Figure 1 is a schematic diagram of the structure of the fingerprint recognition and function key two-in-one module of the embodiment of the present application, refer to Figure 1The fingerprint recognition and function key two-in-one module includes a housing 1, a fingerprint recognition device 2 and a fixing bracket 3. A fingerprint hole 10 is provided on the side of the housing 1. The fingerprint hole 10 is in a runway shape. The fingerprint recognition device 2 is arranged inside the housing 1 corresponding to the fingerprint hole 10. The fingerprint recognition device 2 can move inside the housing 1 along the X-axis direction. The fixing bracket 3 is arranged on one side of the fingerprint recognition device 2 in the Z-axis direction. When the user presses the surface of the fingerprint recognition device 2 (applies force along the X-axis direction), the fingerprint recognition module 2 moves inside the housing 1 along the force direction. The fixing bracket 3 limits the movement stroke of the fingerprint recognition device 2, that is, it can limit the maximum distance of the fingerprint recognition device 2 along the X-axis direction.

[0053] For ease of description, the coordinate system of the drawings of the embodiments of the present application is first explained. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other. The X-axis direction can be understood as the width or length direction of the housing 1 (or, mobile phone), the Y-axis direction corresponds to the length or width direction of the housing 1 (or, mobile phone), and the Z-axis direction corresponds to the thickness direction of the housing 1 (or, mobile phone). Exemplarily, in the embodiments of the present application, the X-axis direction is the width direction of the housing 1, the Y-axis direction is the length direction of the housing 1, and the Z-axis direction is the thickness direction of the housing 1.

[0054] It should be noted that, in order to ensure the overall strength of the terminal (mobile phone), the embodiment of the present application proposes that the fingerprint recognition device 2 can be assembled on the side wall of the terminal in an outside-in manner (in this case, the side of the housing 1 is part of the terminal side wall, and the two can be an integrated structure). That is, the fingerprint recognition device 2 is placed from the outside of the housing 1 into the inside of the housing 1 through the fingerprint hole 10 set on the side of the housing 1 to realize the assembly of the fingerprint recognition device 2. This assembly method only requires cutting off the space occupied by the fingerprint recognition device 2 itself on the housing 1, which can ensure the overall strength of the terminal (mobile phone) as much as possible.

[0055] Figure 2 is an exploded view of the fingerprint recognition and function key two-in-one module of the embodiment of the present application along the Z-axis direction, see Figure 2 , a function key 11 is provided inside the housing 1, and the function key 11 is opposite to the fingerprint hole 10 along the X-axis direction, and the fingerprint recognition device 2 can contact the function key 11 after being pressed from the initial position. In other words, in the initial state, the fingerprint recognition device 2 does not contact the function key 11, and when the fingerprint recognition device 2 is lightly pressed (not in contact with the function key 11) to perform the fingerprint recognition operation, the operation defined by the function key 11 will not be activated. In this embodiment, the function key 11 is a switch key, and when a certain force is applied to drive the fingerprint recognition device 2 to move and contact the function key 11, the function key 11 activates the power on / off function. For example, in the power-on state, after the function key 11 is activated, the display screen of the mobile phone can display the "whether to shut down" operation, and in the power-off state, the function key is activated and the fingerprint recognition operation is performed at the same time, and the terminal (mobile phone) is turned on.

[0056] Continue to see Figure 2 The fingerprint recognition device 2 is provided with a limiting hole 20. In this embodiment, the limiting hole 20 passes through the fingerprint recognition device 2 along the Z axis. The fixing bracket 3 is provided with a positioning bone 30 extending into the limiting hole 20 along the Z axis direction. The length of the positioning bone 30 along the X axis direction is less than the length of the limiting hole 20 along the X axis direction, so that the fingerprint recognition device 2 can move along the X axis direction. When the two ends of the limiting hole 20 along the X axis direction contact the positioning bone 30, the fingerprint recognition device 2 will be prevented from continuing to move, thereby limiting the movement range of the fingerprint recognition device 2.

[0057] Furthermore, the length of the limiting hole 20 along the Y-axis direction is set to be slightly smaller than the length of the positioning bone 30 along the Y-axis direction. Specifically, the distance between the two is between 0.3mm and 0.5mm, which can minimize the movement of the fingerprint recognition assembly 2 relative to the positioning bone 30 along the Y-axis direction.

[0058] The fixed bracket 3 is arranged on one side of the fingerprint recognition device 2 along the Z-axis direction, which saves space at both ends of the fingerprint recognition device 2 along the Y-axis direction, avoids slotting at both ends of the shell 1 corresponding to the fingerprint recognition module 2, and improves the strength of the shell 1; and makes the two ends of the shell 1 corresponding to the fingerprint recognition module 2 have greater strength, and the fixed bracket 3 will not be deformed by force during the process of pressing the fingerprint recognition device 2, thereby extending the service life of the two-in-one module compared with the prior art.

[0059] Figure 3 It is a structural schematic diagram of the housing 1 of the fingerprint recognition and function key two-in-one module of the embodiment of the present application; Figure 4 It is a structural schematic diagram of the fixing bracket 3 of the fingerprint recognition and function key two-in-one module according to an embodiment of the present application.

[0060] See also Figure 1 and Figure 3 The housing 1 is provided with a limiting groove 12, the limiting groove 12 is on the inner side of the fingerprint hole 10, the fingerprint hole 10 is located on the outer side of the limiting groove 12, three through holes 13 are provided between the fingerprint hole 10 and the limiting groove 12, and a spacer bar 14 is provided between two adjacent through holes 13.

[0061] In addition, the function key 11 is arranged at the bottom (YZ surface) of the limiting groove 12 .

[0062] The spacer bar 14 separates the fingerprint hole 10 and the limiting groove 12 along the Y-axis direction, which can limit the travel of the fingerprint recognition device 2. The function key 11 is set at the bottom of the limiting groove 12, so that the fingerprint recognition device 2 moves along the X-axis to the end before contacting the function key 11, effectively avoiding accidental touch operations.

[0063] Furthermore, the housing 1 is provided with threaded holes 120 on both sides of the limiting groove 12 along the Y-axis direction, see Figure 4 The fixing bracket 3 is provided with two mounting holes 300 on the end surface facing away from the positioning bone 30 .

[0064] The fixing bracket 3 is fixedly connected to the housing 1 by means of bolts penetrating through the mounting holes 300 and being threadedly connected to the threaded holes 120 . At this time, the movement of the fingerprint recognition device 2 along the X-axis direction will not drive the fixing bracket 3 .

[0065] Continue to see Figure 3 The housing 1 is provided with a front rib 15 and a rear rib 16 which are opposite to each other along the X-axis direction, and the fixing bracket 3 is limited between the front rib 15 and the rear rib 16 brackets.

[0066] Furthermore, the front rib 15 is provided with a positioning groove 150, and the positioning groove 150 extends from the surface of the front rib 15 in a direction away from the rear rib 16, such as Figure 4 As shown, the fixing bracket 3 is provided with a lip 31 corresponding to the positioning groove 150 , and the lip 31 can be limited in the positioning groove 150 , thereby limiting the fixing bracket 3 from moving along the Y-axis direction.

[0067] Furthermore, a positioning column 17 is provided on one side of the rear guard edge 16 close to the front guard edge 15, and the positioning column 17 extends in the Z-axis direction, that is, the positioning column 17 is perpendicular to the XY plane. Accordingly, the fixed bracket 3 is provided with a positioning hole corresponding to the positioning column 17 (not shown in the drawings), so that when the fixed bracket 3 is installed along the Z-axis, the positioning column 17 can guide the movement of the fixed bracket 3, that is, the length of the positioning column 17 extending in the Z-axis direction is set to allow other components of the shell 1 to preferentially contact the fixed bracket 3.

[0068] Figure 5 It is a structural schematic diagram of the fingerprint recognition device 2 of the fingerprint recognition and function key two-in-one module according to an embodiment of the present application.

[0069] See also Figure 5 The fingerprint recognition device 2 includes a fingerprint recognition component 21, a flexible circuit board 22, and a reinforcing component 23. The fingerprint recognition component 21 and the reinforcing component 23 are respectively attached to two opposite surfaces of the flexible circuit board 22. For example, the fingerprint recognition component 21, the flexible circuit board 22, and the reinforcing component 23 can be attached together by means of thermosetting adhesive or the like.

[0070] At least one end of the fingerprint recognition component 21 close to the reinforcing component 23 is disposed in the fingerprint hole 10, and accordingly, the fingerprint recognition component 21 has an edge of the same shape (track shape) as the fingerprint hole 10. In this embodiment, the end of the fingerprint recognition component 21 away from the reinforcing component 23 protrudes from the fingerprint hole 10 when not pressed, and the user can realize the fingerprint recognition function without applying a large force to press the fingerprint recognition component 21.

[0071] It should be noted that the fingerprint recognition component 21 has a waterproof gasket, which is sealed against the fingerprint hole 10 to prevent water from entering the two-in-one module.

[0072] The reinforcing component 23 is provided with three through holes 13 , that is, a part of the reinforcing component 23 is located in the fingerprint hole 10 , and another part of the reinforcing component 23 is provided with the through holes 13 and is arranged in the limiting groove 12 .

[0073] As can be seen from the above, the flexible circuit board 22 is located in the fingerprint hole 10 and is blocked by the spacer bar 14 so as not to move to the limiting groove 12 .

[0074] The flexible circuit board 22 includes a first portion 221 and a second portion 222 . The first portion 221 is disposed between the fingerprint recognition component 21 and the reinforcing component 23 . The second portion 222 extends from one end of the first portion 221 and is slidably engaged with the housing 1 .

[0075] Combination Figure 1 In this embodiment, the first portion 221 is perpendicular to the XY plane, and the second portion 222 close to the first portion 221 is twisted at a certain angle and then extends along the X-axis direction.

[0076] It can be seen that the second part 222 makes the first part 221 have a certain redundant length. When the fingerprint recognition device 2 is repeatedly clicked and pressed, the first part 221 will have a larger swing radius as the fingerprint recognition device moves, so as to reduce the deformation of the first part 221, thereby reducing the possibility of breakage of the flexible circuit board 22 and improving the service life of the flexible circuit board 22.

[0077] See also Figure 3 The housing 1 is provided with a circuit board slot 18 for accommodating the portion of the second portion 222 extending along the X-axis direction. That is, the portion of the second portion 222 extending along the X-axis direction is buried in the circuit board slot 18 and does not occupy the internal space of the limiting slot 12. When the fingerprint recognition device 2 moves along the X-axis direction, the second portion 222 moves in the circuit board slot 18 along the X-axis direction.

[0078] Continue to see Figure 5 The reinforcing member 23 includes a first reinforcing portion 231 located at both ends of the Y axis and a second reinforcing portion 232 located between the two first reinforcing portions 231. The two first reinforcing portions 231 and the second reinforcing portion 232 are respectively provided with three through holes 13 corresponding to each other.

[0079] In this embodiment, the material of the first reinforcement part 231 is steel to improve the strength of the fingerprint recognition device 2. The material of the second reinforcement part 232 is a non-metallic material. The non-metallic material can be a material such as rubber, rubber, TPU, etc., which has a softer surface hardness than metal and has weak elasticity, so that the second reinforcement part 232 is not easy to damage the function key 11 when pressing the function key 11.

[0080] Furthermore, each of the two first reinforcement parts 231 is provided with a limiting hole 20, and the second reinforcement part 232 can abut the function key 11 when moving along the X-axis direction. In this embodiment, in order to prevent the second reinforcement part 232 from contacting the function key 11 too easily, the length of the first reinforcement part 231 is greater than that of the second reinforcement part 232, and the difference between the lengths of the two is 3mm-3.5mm.

[0081] Furthermore, an elastic pad 2311 is provided at one end of the first reinforcement part 231 away from the fingerprint hole 10, and a conductive base 2321 is provided at one end of the second reinforcement part 232 facing the function key 11. After pressing the fingerprint recognition device 2, the elastic pad 2311 is compressed and deformed along the X-axis direction.

[0082] In this embodiment, the elastic pad 2311 is made of foam, TPU or silicone material. The conductive base 2321 is made of TPU material. The elastic pad 2311 and the first reinforcement part 231 are not limited to being assembled by adhesive or dispensing. Similarly, the conductive base 2321 and the second reinforcement part 232 are not limited to being assembled by adhesive or dispensing.

[0083] Figure 6 2 is a schematic diagram of the state of the fingerprint recognition device when the fingerprint recognition and function key two-in-one module of the embodiment of the present application is not pressed.

[0084] like Figure 6 As shown, when the fingerprint recognition device 2 is not pressed, the elastic pad 2311 has already abutted against the bottom of the limiting groove 12, and the second reinforcement part 232 contacts but does not press the function key 11, so that the corresponding function is not activated. After the fingerprint recognition device 2 is pressed, the elastic pad 2311 is compressed, and the conductive base 2321 of the second reinforcement part 232 presses the function key 11 to activate the corresponding function.

[0085] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
