[0002] With the development of technology, foldable screen mobile phones have become a new type of mobile phone. Most foldable screen mobile phones are designed with an inner foldable screen. Such foldable screen mobile phones generally have two screens. In the unfolded state, the inner screen is mainly used, and in the folded state, the outer screen is mainly used. Currently, existing foldable screen mobile phones usually have a fingerprint module arranged under each of the inner screen and the outer screen. When in the unfolded state, fingerprint unlocking is performed through a fingerprint module on the inner screen. When in the folded state, fingerprint unlocking is performed through a fingerprint module on the outer screen. However, the solution of double fingerprint modules for unlocking the inner and outer screens in the prior art will greatly occupy the internal space of the mobile phone, have a high cost, increase the circuit processing difficulty and power consumption.

[0028] The following will, in conjunction with the accompanying drawings, elaborate on the electronic device 100 provided by the embodiments of the present invention through specific embodiments and their application scenarios.

[0029] As Figure 1 and Figure 3 shown, the electronic device 100 according to the embodiments of the present invention includes a first housing 10, a second housing 20, a fingerprint module 30, a mirror assembly 40, and a rotating arm 61.

[0030] Specifically, referring to Figure 1 and Figure 3 the first housing 10 and the second housing 20 can be rotatably connected through a rotating shaft assembly. A first display screen 51 is disposed on the first side surface of the first housing 10 and the second housing 20. During the relative rotation of the first housing 10 and the second housing 20, the first display screen 51 can be switched between an unfolded state and a folded state. The second display screen 52 is disposed on the second surface of the first housing 10. The fingerprint module 30 is disposed inside the first housing 10, and the fingerprint module 30 has a fingerprint unlocking function. The mirror assembly 40 is disposed inside the first housing 10, and the mirror assembly 40 is rotatably connected to the first housing 10.

[0031] The rotating arm 61 is disposed inside the first housing 10. The first end of the rotating arm 61 is connected to the rotating shaft assembly, and the second end of the rotating arm 61 abuts against the mirror assembly 40. During the relative rotation of the first housing 10 and the second housing 20, the rotating shaft assembly rotates and drives the mirror assembly 40 to rotate through the rotating arm 61. When the first display screen 51 is in the unfolded state, the reflecting surface of the mirror assembly 40 faces the first display screen 51, facilitating fingerprint unlocking. When the first display screen 51 is in the folded state, the reflecting surface of the mirror assembly 40 faces the second display screen 52, facilitating fingerprint unlocking.

[0032] In the present invention, by disposing the fingerprint module 30 and the mirror assembly 40 in the first housing 10 and driving the mirror assembly 40 to rotate through the rotating arm 61, when the electronic device 100 is unfolded, the reflecting surface of the mirror assembly 40 can face the first display screen 51 to achieve fingerprint recognition of the electronic device 100. When the electronic device 100 is folded, the reflecting surface of the mirror assembly 40 can face the second display screen 52 to achieve fingerprint recognition of the electronic device 100. The electronic device 100 of the present invention can achieve fingerprint unlocking in the unfolded state and the folded state respectively by disposing one fingerprint module 30, which is convenient to use, can effectively save the internal occupied space of the electronic device 100, reduce costs, simplify the internal circuit design of the electronic device 100, and reduce power consumption.

[0033] In the present invention, asFigure 3 As shown, a first fingerprint collection area 11 is provided on the first display screen 51, and a second fingerprint collection area 12 is provided on the second display screen 52. When the first display screen 51 is in the unfolded state, the reflecting surface of the mirror assembly 40 faces the first fingerprint collection area 11; when the first display screen 51 is in the folded state, the reflecting surface of the mirror assembly 40 faces the second fingerprint collection area 12.

[0034] In the present invention, referring to Figure 1 and Figure 3 , a first fingerprint collection area 11 (see the dashed box in Figure 1 ) and a second fingerprint collection area 12 (see the dashed box in Figure 3 ) may be provided on the first housing 10 (the first device main body). The first fingerprint collection area 11 and the second fingerprint collection area 12 are transparent areas, and the first fingerprint collection area 11 and the second fingerprint collection area 12 are respectively used for collecting user fingerprints. The second housing 20 is movably connected to the first housing 10. The first housing 10 and the second housing 20 can be unfolded or folded with respect to each other.

[0035] The fingerprint module 30 may be disposed in the first housing 10, and the fingerprint module 30 has a fingerprint recognition surface 31. The mirror assembly 40 is movably disposed in the first housing 10. The electronic device 100 can be switched between the unfolded state and the folded state. When the electronic device 100 is in the unfolded state, as Figure 1 shown, the first housing 10 is unfolded relative to the second housing 20, the mirror assembly 40 faces the first fingerprint collection area 11, and during the fingerprint recognition process of the user, the mirror assembly 40 can guide the light at the first fingerprint collection area 11 to the fingerprint recognition surface 31 for fingerprint image collection. The electronic device 100 realizes fingerprint recognition and unlocking by comparing the collected user fingerprint image with the fingerprint image input by the user.

[0036] When the electronic device 100 is in the folded state, as Figure 3As described above, the first housing 10 is folded relative to the second housing 20, and the mirror assembly 40 faces the second fingerprint collection area 12. The mirror assembly 40 guides the light at the second fingerprint collection area 12 to the fingerprint recognition surface 31 for fingerprint image collection. Similarly, the electronic device 100 compares the collected user fingerprint image with the fingerprint image entered by the user to achieve fingerprint recognition and unlocking. By providing a fingerprint module 30, the electronic device 100 of the present invention can achieve fingerprint unlocking of the electronic device 100 in different states through the first fingerprint collection area 11 and the second fingerprint collection area 12 when the electronic device 100 is in the unfolded state and the folded state. The overall operation is simple and convenient to use, which can effectively save the internal occupied space of the electronic device 100, reduce costs, simplify the internal circuit design of the electronic device 100, and reduce power consumption.

[0037] Of course, the fingerprint module 30 and the mirror assembly 40 can also be provided in the second housing 20, and the first fingerprint collection area 11 and the second fingerprint collection area 12 can also be provided on the second housing 20, which will not be elaborated in detail in the present invention.

[0038] The electronic device 100 of the present invention can be a foldable electronic product such as a foldable mobile phone or a tablet computer. The present invention can use the optical fingerprint principle for fingerprint recognition. Among them, the working principle of optical fingerprint is to utilize the reflection and refraction characteristics of light. When the user presses the display screen to unlock with a finger, the finger area is illuminated by the light source emitted by the display screen, and the reflected light illuminating the fingerprint enters the under-screen photosensitive sensor (fingerprint module 30) through the gaps between the screen pixels. Recognition and unlocking are achieved by comparing the collected fingerprint image with the fingerprint image entered by the user. Of course, for those skilled in the art, the specific working principle of the fingerprint module 30 and fingerprint unlocking can be understood and implemented, which will not be elaborated in detail in the present invention.

[0039] Thus, for the electronic device 100 according to the embodiments of the present invention, a fingerprint module 30 and a mirror assembly 40 are provided in the first housing 10. A first fingerprint collection area 11 and a second fingerprint collection area 12 are provided on the first housing 10. When the electronic device 100 is unfolded, the mirror assembly 40 can guide the light at the first fingerprint collection area 11 to the fingerprint recognition surface 31 of the fingerprint module 30, realizing fingerprint recognition of the electronic device 100. When the electronic device 100 is folded, the mirror assembly 40 can guide the light at the second fingerprint collection area 12 to the fingerprint recognition surface 31 of the fingerprint module 30, realizing fingerprint recognition of the electronic device 100. By providing one fingerprint module 30, the electronic device 100 of the present invention can realize fingerprint recognition through the first fingerprint collection area 11 and the second fingerprint collection area 12 respectively in the unfolded state and the folded state, complete fingerprint unlocking, is convenient to use, can effectively save the internal occupied space of the electronic device 100, reduce costs, simplify the internal circuit design of the electronic device 100, and reduce power consumption.

[0040] In the present invention, as Figure 1 and Figure 3 described, the first display screen 51 can serve as the inner screen of the electronic device 100, and the second display screen 52 can serve as the outer screen of the electronic device 100. In the present invention, taking the electronic device 100 as a foldable dual-screen folding mobile phone as an example, when the electronic device 100 is in the unfolded state, as Figure 1 shown, the first display screen 51 and the second display screen 52 are located on opposite sides of the electronic device 100. The first display screen 51 is the inner screen and serves as the user's usage screen. A first fingerprint collection area 11 is provided at the part of the first display screen 51 located in the first housing 10. When the user touches the first fingerprint collection area 11 with a finger, the mirror assembly 40 can guide the light at the first fingerprint collection area 11 to the fingerprint recognition surface 31 of the fingerprint module 30 to collect a fingerprint image. The electronic device 100 realizes fingerprint recognition and unlocking of the first display screen 51 by comparing the collected user fingerprint image with the fingerprint image entered by the user.

[0041] When the electronic device 100 is in the folded state, as Figure 3As shown, the part of the first display screen 51 located on the first housing 10 is attached to the part of the first display screen 51 located on the second housing 20. The second display screen 52 serves as the outer screen of the electronic device 100. When the electronic device 100 is in the folded state, the second display screen 52 is the screen for user use, and a second fingerprint collection area 12 is provided on the part of the second display screen 52 located on the first housing 10. The mirror assembly 40 guides the light at the second fingerprint collection area 12 to the fingerprint recognition surface 31 for fingerprint image collection. Similarly, the electronic device 100 compares the collected user fingerprint image with the fingerprint image entered by the user to achieve fingerprint recognition and unlocking.

[0042] By providing a fingerprint module 30, the electronic device 100 of the present invention can achieve fingerprint unlocking of the electronic device 100 in different states through the first fingerprint collection area 11 and the second fingerprint collection area 12 when the electronic device 100 is in the unfolded state and the folded state. The overall operation is simple and convenient to use, which can effectively save the internal occupied space of the electronic device 100, reduce costs, simplify the internal circuit design of the electronic device 100, and reduce power consumption.

[0043] According to an embodiment of the present invention, when the electronic device 100 is in the unfolded state, the plane where the mirror assembly 40 is located forms a first angle with the plane where the first display screen 51 is located. When the electronic device 100 is in the folded state, the plane where the mirror assembly 40 is located forms a second angle with the plane where the second display screen 52 is located, and the first angle is equal to the second angle.

[0044] In other words, for the electronic device 100 of the present invention, as Figure 1 and Figure 3 shown, the fingerprint recognition surface 31 of the fingerprint module 30 does not face the screen (the first display screen 51 or the second display screen 52). In the prior art, the fingerprint module 30 usually adopts a design scheme perpendicular to the screen, that is, in the prior art, the fingerprint recognition surface 31 of the fingerprint module 30 usually faces the screen to complete the collection and recognition of fingerprint images. The fingerprint recognition surface 31 of the fingerprint module 30 of the present invention faces the mirror assembly 40, and the mirror assembly 40 forms a certain angle with the fingerprint recognition surface 31 of the fingerprint module 30 when the electronic device 100 is in different states, ensuring that the light at the first fingerprint collection area 11 or the second fingerprint collection area 12 can be reflected or refracted by the mirror assembly 40 onto the fingerprint recognition surface 31 of the fingerprint module 30 for fingerprint image collection and recognition.

[0045] When the electronic device 100 is in the unfolded state, as Figure 1As shown, the plane where the mirror assembly 40 is located forms a first angle with the plane where the first display screen 51 is located. When the electronic device 100 is in the folded state, the plane where the mirror assembly 40 is located forms a second angle with the plane where the second display screen 52 is located. Among them, the first angle is equal to the second angle.

[0046] In the present invention, the first angle and the second angle can be 45°. Taking a folding-screen mobile phone as the electronic device 100 as an example, by arranging a fingerprint module 30 parallel to the mobile phone screen inside the folding-screen mobile phone case (the fingerprint recognition surface 31 of the fingerprint module 30 faces the mobile phone screen when placed vertically) and a cooperating mirror assembly 40, in the folded and unfolded states of the mobile phone, the mirror assembly 40 and the fingerprint module 30 form a specific angle (the first angle or the second angle) to achieve unlocking in the folded and unfolded states. When the mobile phone is in the folded state, as Figure 3 shown, the mirror assembly 40 can transmit the light in the outer screen fingerprint area to the fingerprint module 30 through reflection and refraction to achieve image acquisition. When the mobile phone is in the unfolded state, the mirror assembly 40 can transmit the light in the inner screen fingerprint area to the fingerprint module 30 through reflection and refraction to achieve image acquisition.

[0047] In some specific embodiments of the present invention, when the electronic device 100 is in the unfolded state, the angle between the incident light entering the mirror assembly 40 from the first fingerprint acquisition area 11 and the reflected light reflected by the mirror assembly 40 to the fingerprint module is 90°. When the electronic device 100 is in the folded state, the angle between the incident light entering the mirror assembly 40 from the second fingerprint acquisition area 12 and the reflected light reflected by the mirror assembly 40 to the fingerprint module is 90°.

[0048] For example, when the electronic device 100 is in the folded state, the light of the mirror assembly 40 and the second fingerprint acquisition area 12 of the outer screen forms a 45° angle. After reflection and refraction by the mirror assembly 40, the direction of the light will be deflected by 90°, so that the fingerprint module 30 can detect the fingerprint image, and fingerprint recognition is performed by comparing with the pre-recorded fingerprint pattern.

[0049] In some specific embodiments of the present invention, a first rotation groove is provided at the first end of the rotating arm 61, a part of the rotating shaft assembly is movably provided in the first rotation groove, and the rotating arm 61 can rotate relative to the rotating shaft assembly. A second rotation groove is provided at the second end of the rotating arm 61, and a part of the mirror assembly 40 is provided in the second rotation groove, and the mirror assembly 40 can rotate relative to the rotating arm.

[0050] In the present invention, the mirror assembly 40 includes a mirror and a lens rotating shaft 41. The mirror is rotatable around the lens rotating shaft 41. One end of the rotating arm 61 is movably connected to the mirror, and the other end of the rotating arm 61 is movably connected to the first housing 10. When the electronic device 100 switches between the unfolded state and the folded state, the rotating arm 61 drives the mirror to rotate around the lens rotating shaft 41.

[0051] The mirror assembly further includes a connecting shaft 62. The connecting shaft 62 is disposed in the second rotating groove. The rotating arm 61 is rotatably connected to the mirror through the connecting shaft 62, and the other end of the rotating arm 61 is connected to the first housing 10 through a first rotating shaft 63.

[0052] The rotating shaft assembly includes a bracket 70, a first rotating shaft 63, and a second rotating shaft 71. A part of the bracket 70 is located inside the first housing 10, and another part of the bracket 70 is located inside the second housing 20. The first rotating shaft 63 is disposed on the bracket 70. The bracket 70 is provided with two second rotating shafts 71. One of the second rotating shafts 71 is located inside the first housing 10, and the other second rotating shaft 71 is located inside the second housing 20. The first housing 10 and the second housing 20 can be unfolded or folded respectively around the corresponding second rotating shaft 71.

[0053] The connection line between the axis of the first rotating shaft 63 and the axis of the second rotating shaft 71 located in the first housing 10 is parallel to the extension line of the plane where the mirror is located.

[0054] Specifically, as Figure 3 shown, a lens rotating shaft 41 can be provided inside the first housing 10. When the mirror assembly 40 switches between the unfolded state and the folded state around the lens rotating shaft 41, a rotating arm 61 can also be provided inside the first housing 10. One end of the rotating arm 61 is movably connected to the mirror assembly 40, and the other end of the rotating arm 61 is movably connected to the first housing 10. When the electronic device 100 switches between the unfolded state and the folded state, the rotating arm 61 can drive the mirror assembly 40 to rotate around the lens rotating shaft 41, realizing the rotation of the mirror assembly 40 inside the first housing 10, so that the mirror assembly 40 can rotate to a position corresponding to the first fingerprint acquisition area 11 and the second fingerprint acquisition area 12, ensuring that in different states of the electronic device 100, the light can be reflected to the fingerprint module 30 through the mirror assembly 40, realizing fingerprint unlocking in different states of the electronic device 100.

[0055] Optionally, one end of the rotating arm 61 can be connected to the mirror assembly 40 through a connecting shaft 62, and the other end of the rotating arm 61 can be connected to the first housing 10 through a first rotating shaft 63. When the electronic device 100 switches between the unfolded state and the folded state, the rotating arm 61 can rotate around the first rotating shaft 63, and then drive the mirror assembly 40 to rotate around the lens rotating shaft 41 through the connecting shaft 62 of the mirror assembly 40, so as to realize the angle adjustment of the mirror assembly 40.

[0056] In some specific embodiments of the present invention, referring to Figure 1 and Figure 3 , a bracket 70 can also be provided in the electronic device 100. A part of the bracket 70 is located inside the first housing 10, and another part of the bracket 70 is located inside the second housing 20. The first rotating shaft 63 is installed on the bracket 70. The bracket 70 can also be provided with two second rotating shafts 71. One of the second rotating shafts 71 is located inside the first housing 10, and the other second rotating shaft 71 is located inside the second housing 20. The first housing 10 and the second housing 20 can be unfolded or folded respectively around the corresponding second rotating shafts 71, so as to realize the free switching of the electronic device 100 between the unfolded state and the folded state.

[0057] In some specific embodiments of the present invention, the line connecting the axis of the first rotating shaft 63 and the axis of the second rotating shaft 71 located in the first housing 10 is parallel to the extension line of the plane where the mirror assembly 40 is located. Structures such as the rotating arm 61, the mirror assembly 40, and the bracket 70 can form a parallel double-crank linkage mechanism. When the electronic device 100 is in the unfolded state, the distance from the axis of the second rotating shaft 71 to the side of the first housing 10 provided with the first fingerprint collection area 11 is the first distance. When the electronic device 100 is in the folded state, the distance from the axis of the second rotating shaft 71 to the central plane between the first housing 10 and the second housing 20 is the second distance, and the first distance is less than or equal to the second distance.

[0058] That is to say, in the electronic device 100 of the present invention, the fingerprint module 30 is designed in one of the two mobile phone bodies (the first housing 10 and the second housing 20), namely the first housing 10. Different from the conventional design of the folding screen where two fingerprint recognition modules are placed perpendicular to the screen, in the present invention, the fingerprint module 30 is placed parallel to the screen. The mirror assembly 40 and the lens rotating shaft 41 are designed in the same housing (inside the first housing 10) as the fingerprint module 30. The first housing 10 is connected to the bracket 70 through the second rotating shaft 71. One end of the rotating arm 61 is connected to the mirror assembly 40 through the connecting shaft 62, and the other end is connected to the first rotating shaft 63. The first rotating shaft 63 is fixed on the bracket 70. The body rotating shaft and the first rotating shaft 63 are designed with non-concentric centers, and the eccentric distance can be calculated according to the actual dimensions of the structural parts, which will not be elaborated in detail in this application. Of course, a rotating arm 64 can also be designed inside the second housing 20, and its purpose is to adjust whether the fingerprint is to be placed inside the second housing 20 according to the actual layout plan and folding requirements. The outer screen glass cover plate is transparent, and the second fingerprint collection area 12 can ensure that light passes through. The object supporting the fingerprint recognition area (the first fingerprint collection area 11) under the inner screen is also transparent or can ensure that light can pass through.

[0059] When the electronic device 100 is in the folded state, as Figure 3 shown, when unlocking by pressing the second fingerprint collection area 12 on the outer screen (the second display screen 52) of the mobile phone with a finger, the light of the mirror assembly 40 and the outer screen fingerprint collection area (the second fingerprint collection area 12) forms a 45-degree angle. After being reflected and refracted by the mirror assembly 40, the direction of the light will deflect by 90 degrees, so that the fingerprint module 30 can detect the fingerprint image and perform fingerprint recognition after comparing with the pre-recorded fingerprint pattern.

[0060] When the electronic device 100 is being converted from the folded state to the opened state, refer to Figure 4 and Figure 5 and

[0061] When the electronic device 100 is in the opened state, the user presses the first fingerprint collection area 11 on the inner screen (the first display screen 51) of the mobile phone to unlock the fingerprint. Specifically,

[0062] When the electronic device 100 is fully opened, as Figure 1 and Figure 2 shown, the posture of the mirror assembly 40 just rotates 90 degrees relative to the folded state. Among them, refer to Figure 2, the axis center of the first rotation axis 63 is denoted as O1, the axis center of the second rotation axis 71 of the first housing 10 is denoted as O2, and the connection line L1 of O1 and O2 is always parallel to the mirror assembly 40. The axis center of the connection shaft 62 is denoted as O3, the connection line of O1 and O3 is L2, the axis center of the lens rotation shaft 41 is denoted as O4, and the connection line of O3 and O4 is denoted as L3, and the connection line of O4 and O2 is denoted as L4. In this way, L1, L2, L3 and L4 together can form a parallel double crank linkage mechanism. During the rotation process, since the mirror assembly 40 is always parallel to L1, the angle of the mirror assembly 40 relative to the horizontal plane will not change.

[0063] When the electronic device 100 is switched from the folded state to the opened state or from the opened state to the folded state, the rotation angle of the electronic device 100 is 90 degrees. Therefore, the angle of the mirror assembly 40 relative to the inner screen and the outer screen of the mobile phone will also change by 90 degrees. When the electronic device 100 is in the opened state, the angle between the mirror assembly 40 and the inner screen (the first display screen 51) is 45 degrees. When the electronic device 100 is switched to the folded state, since the electronic device 100 rotates 90 degrees, the angle between the mirror assembly 40 and the inner screen is -45 degrees. At the same time, the distance X1 from the body rotation axis to the surface of the first display screen 51 and the distance X2 from the body rotation axis to the flatness of the middle plane of the first housing 10 and the second housing 20 need to meet the condition: X1 ≤ X2, otherwise the electronic device 100 will interfere and cannot be fully folded. At the same time, X1 and X2 should not differ too much, which will increase the thickness of the mobile phone. The specific dimensions can be calculated according to the actual structure design.

[0064] When the electronic device 100 is unfolded, as Figure 1 shown, the light of the first fingerprint collection area 11 of the mirror assembly 40 and the inner screen forms a 45-degree angle. After being reflected and refracted by the mirror assembly 40, the direction of the light will be deflected by 90 degrees, so that the fingerprint image can be detected by the fingerprint module 30, and fingerprint recognition is performed by comparing with the pre-recorded fingerprint pattern. During the use of the electronic device 100, the switching between its folded and opened states can drive the switching of different working postures of the mirror assembly 40, so as to realize fingerprint unlocking in both the folded and opened states.

[0065] The electronic device 100 of the present invention realizes the unlocking of the inner and outer screens in the folded and opened states by a fingerprint module 30 by adjusting different postures of the electronic device 100 in the folded and opened states. The electronic device 100 of the present invention has the characteristics of simple structure, convenient use, strong feasibility, etc., saves the internal stacking space of the mobile phone, simplifies the circuit design and power consumption of the mobile phone, etc., and at the same time saves costs, providing a new design idea for fingerprint recognition of foldable screen mobile phones.

[0066] In summary, for the electronic device 100 according to an embodiment of the present invention, a fingerprint module 30 and a mirror assembly 40 are provided in the first housing 10. A first fingerprint collection area 11 and a second fingerprint collection area 12 are provided on the first housing 10. When the electronic device 100 is unfolded, the mirror assembly 40 can guide the light at the first fingerprint collection area 11 to the fingerprint recognition surface 31 of the fingerprint module 30, realizing fingerprint recognition of the electronic device 100. When the electronic device 100 is folded, the mirror assembly 40 can guide the light at the second fingerprint collection area 12 to the fingerprint recognition surface 31 of the fingerprint module 30, realizing fingerprint recognition of the electronic device 100. By providing one fingerprint module 30, the electronic device 100 of the present invention can realize fingerprint recognition through the first fingerprint collection area 11 and the second fingerprint collection area 12 respectively in the unfolded state and the folded state, complete fingerprint unlocking, which is convenient to use, can effectively save the internal occupied space of the electronic device 100, reduce costs, simplify the internal circuit design of the electronic device 100, and reduce power consumption.
