[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0053] The following is combined Figures 1-13 This invention describes the electronic device.

[0054] It is understood that the electronic device 1 of this utility model can be a mobile phone, a translator, a learning machine, a laptop computer, or other electronic devices, which need to be used as tools for interaction between two parties in some practical scenarios.

[0055] like Figure 1 and Figure 2 As shown, this utility model provides an electronic device 1, including: a hinge mechanism 11, a limiting mechanism 12, a first screen 13, and a second screen 14. The hinge mechanism 11 includes a base 111 and two rocker arms 112, which are rotatably mounted on the base 111. The limiting mechanism 12 is connected to each of the two rocker arms 112 and is used to lock the two rocker arms 112 when they are extended to a preset extension angle. The first screen 13 and the second screen 14 are respectively connected to the two rocker arms 112 in a one-to-one correspondence. When the two rocker arms 112 are extended to the preset extension angle, the screen sides of the first screen 13 and the second screen 14 face opposite directions.

[0056] In this embodiment, the electronic device 1 connects the first screen 13 and the second screen 14 to two rocker arms 112 of the hinge mechanism 11, and rotatably mounts the two rocker arms 112 on the base 111. The relative rotation of the two rocker arms 112 causes the first screen 13 and the second screen 14 to unfold relative to each other, adjusting their angles to meet usage requirements. The first screen 13 and the second screen 14 can either be in a close-fitting state to reduce space occupation and facilitate storage or carrying, or unfolded to a specific angle for user use.

[0057] Specifically, when the two rocker arms 112 are extended to a preset extension angle, the first screen 13 and the second screen 14 are arranged back-to-back, with the screen sides of the first screen 13 and the second screen 14 facing opposite sides, so that two users can view the content displayed on the first screen 13 and the second screen 14 face-to-face and interact with each other through the electronic device 1 of this embodiment. For example, when the electronic device 1 is a translator, it can translate the speech of two users into the languages ​​selected by the two users and display the translation on the first screen 13 and the second screen 14 to facilitate communication between the two users; or, the electronic device 1 can also be a teaching aid, where one user can operate one screen and display the relevant content on the other screen to demonstrate and explain to the other user.

[0058] In addition, by setting a limiting mechanism 12 connected to the two rocker arms 112, when the two rocker arms 112 are extended to a preset extension angle, the limiting mechanism 12 can lock the position of the two rocker arms 112 to maintain the relative position and angle of the first screen 13 and the second screen 14. When two users are interacting and communicating through the electronic device 1, they can hold one of the screens or place it on a platform such as a desktop, without having to manually maintain the extension angle of the two screens, making it more convenient to use.

[0059] The electronic device 1 of this invention connects two relatively rotatable rocker arms 112 to a first screen 13 and a second screen 14 respectively. Rotating the two rocker arms 112 adjusts the angle of the first screen 13 and the second screen 14. The two rocker arms 112 can be extended to a preset extension angle so that the first screen 13 and the second screen 14 face two users facing each other. The two users can view the content displayed on the screen facing them respectively, so as to interact with each other through the electronic device 1. At the same time, a limiting mechanism 12 is set to lock the two rocker arms 112 when they are extended to the preset extension angle, so as to maintain the first screen 13 and the second screen 14 at an angle that is convenient for the two users to view face to face. No manual maintenance is required, making it convenient and easy to use.

[0060] Therefore, the electronic device 1 of this utility model, by setting a hinge mechanism 11 to adjust the angle of the first screen 13 and the second screen 14, can unfold the first screen 13 and the second screen 14 to an angle that is convenient for two users to communicate and use. The limiting mechanism 12 locks the first screen 13 and the second screen 14 at this angle, which is convenient for two users to interact. This effectively solves the defect of the translation device in the prior art that is inconvenient to use in application scenarios where two parties are communicating.

[0061] It is understandable that in some specific embodiments, such as Figure 1 As shown, the first screen 13 can be the main screen, and the second screen 14 can be the secondary screen. The area of ​​the first screen 13 is larger than the area of ​​the second screen 14. A stepped surface is formed on the back panel side of the first screen 13, which includes a first surface, a transition surface, and a second surface; wherein, the height of the first surface is lower than the height of the second surface, the first surface is connected to the second surface through the transition surface, and the first surface and the back panel side of the second screen 14 are correspondingly arranged. When the two rocker arms 112 of the hinge mechanism 11 are extended to the minimum extension angle, the back panel side of the second screen 14 is in contact with the first surface, one sidewall between the back panel side and the screen side of the second screen 14 is in contact with the transition surface, and the screen side and the second surface of the second screen 14 are flush.

[0062] In some embodiments, such as Figure 2 As shown, the hinge mechanism 11 also includes a torque member 113; the torque member 113 is disposed between the two rocker arms 112 and is used to drive the two rocker arms 112 to drive the first screen 13 and the second screen 14 to unfold relative to each other.

[0063] In this embodiment, a torque member 113 is provided between the two rocker arms 112. The torque member 113 can be connected to at least one rocker arm 112. When the two rocker arms 112 approach each other, the torque member 113 is twisted by the pressure of the rocker arm 112 connected to the torque member 113. When the two rocker arms 112 are released, the torque member 113 can drive the connected rocker arm 112 to rotate away from the other rocker arm 112 to make the two rocker arms 112 unfold, thereby driving the first screen 13 and the second screen 14 to unfold. It is understood that the torque member 113 can also be connected to both rocker arms 112 to synchronously drive the two rocker arms 112 to rotate and unfold to both sides. The torque member 113 can realize the automatic unfolding of the first screen 13 and the second screen 14. When the two rocker arms 112 are unfolded to a preset unfolding angle, they are locked by the limiting mechanism 12, so that the orientation of the first screen 13 and the second screen 14 meets the usage requirements of mutual interaction, without the need for manual unfolding, making it convenient to use.

[0064] In some embodiments, such as Figure 2 and Figure 3As shown, the limiting mechanism 12 includes a stop member 121, which is disposed on the base 111. The stop member 121 is provided with a stop portion 1211 corresponding to the two rocker arms 112. When the two rocker arms 112 are extended to a preset extension angle, the two rocker arms 112 respectively abut against the corresponding stop portion 1211.

[0065] In this embodiment, the stop member 121 is disposed on the base 111 to maintain the fixed position of the stop member 121. By providing two stop portions 1211 on the stop member 121, when the two rocker arms 112 reach the preset unfolding angle, the stop portions 1211 can abut against the two rocker arms 112 respectively to prevent the two rocker arms 112 from continuing to unfold to both sides. The two stop portions 1211, together with the torque member 113, can maintain the two rocker arms 112 at the preset unfolding angle, thereby maintaining the angle of the first screen 13 and the second screen 14.

[0066] Furthermore, such as Figure 2 and Figure 4 As shown, in some embodiments, the limiting mechanism 12 further includes a mounting base 122, a first elastic element 123, and a limiting contact 124; at least one rocker arm 112 is provided with a helical groove. The mounting base 122 is disposed on the base 111, and the first elastic element 123 is axially extendable along the rotation axis of the rocker arm 112. One end of the first elastic element 123 abuts against the mounting base 122, and the other end abuts against the limiting contact 124, so that the limiting contact 124 abuts against the groove edge of the helical groove. When the rocker arm 112 rotates, the limiting contact 124 slides along the extension direction of the groove edge, and the groove edge controls the axial movement of the limiting contact 124 along the rotation axis of the rocker arm 112.

[0067] In this embodiment, the mounting base 122 is used to install on the base 111 to provide a fixed support point. One end of the first elastic member 123 abuts against the mounting base 122, and the other end abuts against the limiting contact 124, pressing the limiting contact 124 against the groove edge of the spiral groove. When the rocker arm 112 rotates, the limiting contact 124 and the first elastic element 123 do not rotate synchronously. The limiting contact 124 moves along the edge of the groove during the rotation of the spiral groove, thereby moving axially along the axis of the rocker arm 112, which in turn changes the compression of the first elastic element 123. The elastic force generated after the first elastic element 123 is compressed will act on the rocker arm 112 through the limiting contact 124, generating resistance to the rocker arm 112. When the unfolding angle of the rocker arm 112 is different, the resistance generated by the limiting contact 124 is also different. By reasonably setting the shape and size of the limiting contact 124 and the spiral groove, the resistance of the limiting contact 124 can prevent the rocker arm 112 from continuing to unfold or rebound when it unfolds to a specific angle. Together with the stop 121, it plays a limiting role on the rocker arm 112, so that the first screen 13 and the second screen 14 will neither continue to unfold outward nor rebound after unfolding to the set angle.

[0068] In some embodiments, the groove edge includes an inclined portion and a vertical portion connected together. The inclined portion is inclined relative to the axial direction of the rocker arm 112, and the vertical portion is perpendicular to the axial direction of the rocker arm 112. When the two rocker arms 112 are extended to a preset extension angle, the limiting contact 124 abuts against the vertical portion of the spiral groove.

[0069] In this embodiment, by dividing the groove edge into an inclined portion that is inclined relative to the axial direction of the rocker arm 112 and a vertical portion that is perpendicular to the axial direction of the rocker arm 112, when the limiting contact 124 is located in the inclined portion, the component of the pressure of the first elastic member 123 on the limiting contact 124 in the direction parallel to the inclined portion will drive the limiting contact 124 to continue moving towards the vertical portion; when the limiting contact 124 reaches the vertical portion and abuts against the vertical portion, the pressure of the first elastic member 123 on the limiting contact 124 will be offset by the reaction force of the vertical portion on the limiting contact 124, and the limiting contact 124 will be limited by the side inclined portion and remain in the position of the vertical portion, so that the rocker arm 112 no longer continues to rotate, and the two rocker arms 112 are restricted to a preset unfolding angle.

[0070] In some embodiments, there are two inclined portions, which are respectively connected to the two ends of the vertical portion and are arranged opposite to each other, so that the groove edge is an arc-shaped groove edge with a central concave shape. When the two rocker arms 112 are extended to a preset extension angle, the limiting contact 124 abuts against the vertical portion. The inclined portions on both sides of the vertical portion can limit the limiting contact 124, so that the rocker arms 112 will not continue to extend outward or rebound.

[0071] In some embodiments, the preset unfolding angle is no greater than 120°.

[0072] In this embodiment, by limiting the preset unfolding angle to no more than 120°, when the two rocker arms 112 are unfolded to the preset unfolding angle, the first screen 13 and the second screen 14 can form a V-shaped structure. The screen side of the first screen 13 and the screen side of the second screen 14 are respectively located on the outer side of the two sides of the V-shaped structure. The V-shaped structure can be placed on a platform such as a desktop with the support of the two sides, and the screen sides of the two screens face diagonally upward, which is convenient for users on both sides to view. The structure is simple, convenient and practical.

[0073] In one specific embodiment, the preset unfolding angle is 120°.

[0074] In some embodiments, such as Figures 5 to 13As shown, the electronic device 1 also includes a locking mechanism 15, which is disposed between the first screen 13 and the second screen 14. The locking mechanism 15 can switch between a locked state and an unlocked state. In the locked state, the locking mechanism 15 locks the first screen 13 and the second screen 14 at their minimum unfolding angle. In the unlocked state, the first screen 13 and the second screen 14 can unfold relative to each other.

[0075] In this embodiment, a locking mechanism 15 is provided between the first screen 13 and the second screen 14. The locking mechanism 15 can switch to the locked state when the first screen 13 and the second screen 14 are set at their minimum unfolding angle to lock the first screen 13 and the second screen 14, thereby reducing the space occupied by the entire electronic device 1 and making it convenient to store and carry. When it is necessary to unfold the first screen 13 and the second screen 14 to each other, the locking mechanism 15 can be switched to the unlocked state.

[0076] It is understood that the locking mechanism 15 can be used in conjunction with the torque member 113 in the aforementioned embodiments. Specifically, when the first screen 13 and the second screen 14 are at their minimum unfolding angle, the torque member 113 is compressed and twisted by the two rocker arms 112. The locking mechanism 15 is used to lock the first screen 13 and the second screen 14 to prevent the torque member 113 from unfolding the first screen 13 and the second screen 14 for storage and carrying. When it is necessary to unfold the first screen 13 and the second screen 14, the locking mechanism 15 is switched to the unlocked state, which releases the first screen 13 and the second screen 14, allowing them to unfold automatically under the drive of the torque member 113.

[0077] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the locking mechanism 15 includes a first magnetic element 151, a first operating element 152, and a second magnetic element 153. The first magnetic element 151 is movably disposed on the first screen 13, and the second magnetic element 153 is disposed on the second screen 14. The first operating element 152 is connected to the first magnetic element 151. The first operating element 152 is used to drive the first magnetic element 151 to move to adjust the relative position of the first magnetic element 151 and the second magnetic element 153, so that the first magnetic element 151 and the second magnetic element 153 attract or repel each other.

[0078] In this embodiment, by respectively providing a first magnetic element 151 and a second magnetic element 153 on the first screen 13 and the second screen 14, the first magnetic element 151 can be moved and adjusted in position under the drive of the first operating element 152. When the first magnetic element 151 moves so that at least one magnetic pole of the first magnetic element 151 and the opposite magnetic pole of the second magnetic element 153 are opposite to each other, the first magnetic element 151 and the second magnetic element 153 can attract each other, thereby locking the first screen 13 and the second screen 14; when the first magnetic element 151 moves so that at least one magnetic pole of the first magnetic element 151 and the like magnetic pole of the second magnetic element 153 are opposite to each other, the first magnetic element 151 and the second magnetic element 153 can repel each other, allowing the first screen 13 and the second screen 14 to unfold.

[0079] It is understandable that when it is necessary to switch the locking mechanism 15 to the unlocked state, the first operating member 152 can also be used to offset the two magnetic poles of the first magnetic member 151 and the second magnetic member 153 that are attracted to each other, so that the two magnetic poles stop attracting each other.

[0080] In one specific embodiment, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the locking mechanism 15 also includes a fixed base, on which a plurality of first magnetic elements 151 are spaced apart along the length direction. The S and N poles of the first magnetic elements 151 are arranged along the length direction of the fixed base. A sliding groove is provided on the first screen 13, and the fixed base is slidably disposed in the sliding groove. A second elastic element abuts between the first end of the fixed base and the sliding groove. A slot is provided at the second end of the sliding groove. A first operating element 152 is connected to the fixed base and extends to the outside of the first screen 13 through the slot. The first operating element 152 is provided with an abutting part that abuts against the groove wall at the second end of the sliding groove. A plurality of second magnetic elements 153 are provided on the second screen 14, each corresponding to one of the first magnetic elements 151. The S and N poles of the second magnetic elements 153 are also arranged along the length direction of the fixed base.

[0081] When the first operating member 152 is not subjected to force, the second elastic member can keep the abutting part on the first operating member 152 in contact with the second end of the slide groove. The S pole of the first magnetic member 151 and the N pole of the corresponding second magnetic member 153 are arranged opposite each other, and the N pole of the first magnetic member 151 and the S pole of the corresponding second magnetic member 153 are arranged opposite each other, so that the first magnetic member 151 and the second magnetic member 153 attract each other. When the first operating member 152 is pressed, the fixed seat can slide along the slide groove, so that the magnetic poles of the first magnetic member 151 and the second magnetic member 153 that attract each other are misaligned, so that the first magnetic member 151 and the second magnetic member 153 are separated from each other, so that the first screen 13 and the second screen 14 can be unfolded together.

[0082] Alternatively, in another embodiment, such as Figure 11 , Figure 12 and Figure 13 As shown, the locking mechanism 15 also includes a latching member 154 and a second operating member 155. The latching member 154 is movably disposed on the first screen 13, and the second screen 14 has a latching slot 141 corresponding to the position of the latching member 154. The second operating member 155 is connected to the latching member 154. The second operating member 155 is used to drive the latching member 154 to move, so that the latching member 154 engages or disengages from the latching slot 141.

[0083] In this embodiment, by providing a latching member 154 and a latching slot 141 on the first screen 13 and the second screen 14 respectively, the latching member 154 can move under the drive of the second operating member 155 so that the latching member 154 extends into the latching slot 141 and latches with the latching slot 141, thereby locking the first screen 13 and the second screen 14, or disengaging from the latching slot 141 so that the first screen 13 and the second screen 14 can unfold each other.

[0084] In some embodiments, such as Figure 13 As shown, a wear-resistant part 142 is provided on the groove wall of the snap-fit ​​groove 141. When the snap-fit ​​part 154 is snapped into the snap-fit ​​groove 141, the snap-fit ​​part 154 abuts against the wear-resistant part 142.

[0085] In this embodiment, by providing a wear-resistant part 142 on the groove wall of the snap-fit ​​groove 141, and by having the snap-fit ​​part 154 abut against the wear-resistant part 142 when it extends into the snap-fit ​​groove 141, the snap-fit ​​groove 141 and the snap-fit ​​part 154 are snapped together. The wear-resistant part 142 has good wear resistance and can prevent the snap-fit ​​part 154 from directly contacting the second screen 14 and scratching and damaging the second screen 14 during the process of entering and exiting the snap-fit ​​groove 141.

[0086] Specifically, in some embodiments, such as Figure 11 , Figure 12 and Figure 13 As shown, the first screen 13 is provided with a mounting slot 131, which has a first slot and a second slot. The first slot corresponds to the snap-fit ​​slot 141, and the second slot is located on the back panel side of the first screen 13. The snap-fit ​​member 154 is movably disposed in the mounting slot 131; the second operating member 155 extends out of the first screen 13 through the second slot; the second operating member 155 is used to drive the snap-fit ​​member 154 to extend out of or retract from the first slot into the mounting slot 131.

[0087] In this embodiment, the mounting slot 131 is used to mount the snap-fit ​​component 154 and the second operating component 155, preventing these moving mechanisms from being exposed outside the first screen 13, thus improving aesthetics. The mounting slot 131 has a first notch corresponding to the snap-fit ​​slot 141. The snap-fit ​​component 154 can extend through the first notch under the drive of the second operating component 155 to snap into the snap-fit ​​slot 141, or retract from the first notch into the mounting slot 131 to disengage from the snap-fit ​​slot 141. Simultaneously, the mounting slot 131 also has a second notch, allowing the second operating component 155 to extend outside the first screen 13, facilitating user operation. Furthermore, by positioning the second notch on the back panel side of the first screen 13, the operating end of the second operating component 155 is located on the back panel side of the first screen 13, separating it from other operation buttons on the first screen 13 and effectively preventing accidental touches by the user.

[0088] In some embodiments, such as Figure 13 As shown, a third elastic member is also provided in the mounting groove 131. One end of the third elastic member abuts against the groove wall of the mounting groove 131 away from the first groove opening, and the other end abuts against the side of the snap-fit ​​member 154 away from the first groove opening, so that at least a part of the snap-fit ​​member 154 extends out from the first groove opening to snap into the snap-fit ​​groove 141. The second operating member 155 extends out through the second groove opening, the opening direction of which is perpendicular to the extension and retraction direction of the third elastic member. The user can push the second operating member 155 away from the first groove opening to make the snap-fit ​​member 154 completely retract into the mounting groove 131, thereby disengaging from the snap-fit ​​groove 141, so as to unfold the first screen 13 and the second screen 14. When the user releases the hand, the third elastic member rebounds, and part of the snap-fit ​​member 154 extends out from the first groove opening again to snap into the snap-fit ​​groove 141. The structure is simple and the operation is convenient.
