Description

electronic equipment

The present invention relates to an electronic device, and in particular to an electronic device including a display screen.

All-in-One (AIO) computers currently on the market integrate various computer components into the display, reducing the overall size of the computer and simplifying the number of cables. However, AIOs lack portability and are difficult to expand. While AIOs can be connected to laptops for shared use, system integration and file transfer are inconvenient. Furthermore, a laptop placed next to an AIO takes up more desk space, and the distance and height difference between the two monitors make viewing difficult for users.

The present invention provides an electronic device that has a large screen and good portability and expandability.

The electronic device of the present invention includes an electronic device, a display screen, and a connection assembly. The electronic device has a first electrical connection portion, an opposing first display surface, and a first rear surface, with the first electrical connection portion located on the first rear surface.

In one embodiment of the present invention, when the angle between the second back surface and the first connecting plate is less than 180 degrees, a first magnetic attraction force greater than the torsional force is exerted between the first connecting plate and the first back surface of the electronic device. When the angle between the second back surface and the first connecting plate is greater than 180 degrees and less than 225 degrees, a second magnetic attraction force greater than the first magnetic attraction is exerted between the first connecting plate and the first back surface of the electronic device. When the angle between the second back surface and the first connecting plate is greater than 225 degrees, a third magnetic attraction force less than the torsional force is exerted between the first connecting plate and the first back surface of the electronic device.

The magnetic strength of the connecting plate magnetic elements located above the second electrical connection portion is greater than the magnetic strength of at least a portion of the connecting plate magnetic elements located below the second electrical connection portion. Furthermore, the magnetic strength of the connecting plate magnetic elements decreases as the position is further away from the pivot structure.

In one embodiment of the present invention, the display screen has a second display surface and a second back surface opposite each other. The second back surface has a plurality of display screen magnetic elements. The first connecting plate is adapted to be attached to the second back surface by magnetic attraction between the connecting plate magnetic elements and the display screen magnetic elements. The magnetic strength of each display screen magnetic element is less than the magnetic strength of each connecting plate magnetic element, and the magnetic strength of the display screen magnetic elements decreases as the position is farther from the pivot structure.

In one embodiment of the present invention, the aforementioned counterweight unit is movably mounted on the display screen. The electronic device further includes at least one motion sensor and a counterweight unit controller. The at least one motion sensor is mounted on at least one of the first connecting plate and the pivot structure to sense the rotation angle and direction of the first connecting plate relative to the display screen.

When the angle between the second rear surface and the first connecting plate is less than 180 degrees, the locking mechanism locks the electronic device to the first connecting plate. When the angle between the second rear surface and the first connecting plate is greater than 180 degrees, the locking mechanism releases the electronic device.

In one embodiment of the present invention, the locking mechanism includes a locking assembly and a linkage mechanism. The locking assembly is movably disposed on the first connecting plate. The linkage mechanism is coupled to a pivot structure. The pivot structure is adapted to drive the locking assembly to move via the linkage mechanism to lock or release the electronic device.

The two hooks are adapted to engage with the electronic device by the elastic force of the elastic member. The linkage mechanism is adapted to resist the elastic force of the elastic member and drive the two hooks away from each other to release the electronic device.

Based on the above, in the electronic device of the present invention, the display screen is equipped with a connection assembly, allowing the electronic device to be connected to the display screen via the connection assembly. Furthermore, the display screen can receive signals from the electronic device via the connection assembly. Consequently, the electronic device of the electronic device can serve as the computing core, while the display screen is primarily used for displaying large-scale images. Consequently, the user can use the electronic device as a portable device alone, while using the display screen as an expansion screen for the electronic device. Furthermore, the electronic device is magnetically connected to the connection assembly, and the pivoting motion of the connection assembly allows the relative angle between the electronic device and the display screen to be changed, making it easy for the user to attach and detach the electronic device and adjust the angle of the electronic device as needed. Furthermore, the second electrical connection portion of the first connection plate of the connection assembly is located between the geometric center of the first connection plate and the pivot structure, placing the second electrical connection portion close to the edge of the first connection plate (the pivot structure). Consequently, the first electrical connection portion of the electronic device is correspondingly close to the edge of the electronic device, making it easier for the electronic device to connect to an expanded keyboard device via its first electrical connection portion.

Figures 1A to 1C respectively illustrate different usage states of at least some components of an electronic device according to an embodiment of the present invention. Figures 2A to 2C are top views of the electronic device of Figures 1A to 1C, respectively. Referring to Figures 1A to 2C, the electronic device 100 of this embodiment includes an electronic device 110, a display screen 120, and a connection assembly 130. The connection assembly includes a first connection board 132 and a hinge structure 134, and a side 1201 of the display screen 120 is hinged to the first connection board 132 via the hinge structure 134. The electronic device 110 is, for example, a tablet PC and has a first display surface 110a and a first back surface 110b opposite to each other. The display screen 120 has a second display surface 120a and a second back surface 120b opposite to each other.

In this embodiment, the connection assembly 130 is non-detachably connected to the side 1201 of the display screen 120 via a hinge structure 134, for example. However, the present invention is not limited thereto. In other embodiments, the display screen 120 may include a detachable portion, and the connection assembly 130 may be pivotally connected to the detachable portion via the hinge structure 134. In this way, the connection assembly 130, the hinge structure 134, and the detachable portion may be considered an external connection module that can be detachably mounted on the display screen 120.

The electronic device 110 is adapted to be mounted on the first connecting plate 132, as shown in Figures 1B and 2B , with the first display surface 110a and the second display surface 120a facing the same direction. Furthermore, the electronic device 110 is adapted to change the angle of the first display surface 110a relative to the second display surface 120a by flipping the first connecting plate 132 relative to the display screen 120, as shown in Figures 1C and 2C . When the electronic device 110 is not mounted on the first connecting plate 132, the first connecting plate 132 can be closed to the second rear surface 120b of the display screen 120, as shown in Figures 1A and 2A . Furthermore, when the electronic device 110 is mounted on the first connecting plate 132, the electronic device 110 can be closed to or unfolded from the second rear surface 120b of the display screen 120 by pivoting the display screen 120 and the first connecting plate 132 relative to each other (as shown in Figures 1C and 2C).

Figure 3 is a front view of the electronic device of Figure 1A. Figure 4 is a front view of the electronic device of Figure 1B. Figure 5 is a rear view of the electronic device of Figure 4. Referring to Figures 3 to 5, in detail, the electronic device 110 of this embodiment has a first electrical connection portion 112, which is located on the first rear surface 110b of the electronic device 110. The first connection plate 132 has a second electrical connection portion 132a. In the state shown in Figure 4 , the first back surface 110b of the electronic device 110 and the first connecting plate 132 are magnetically attracted to each other, allowing the electronic device 110 to be mounted on the first connecting plate 132. Furthermore, the first electrical connection portion 112 and the second electrical connection portion 132a are electrically connected to each other, allowing the display screen 120 to receive signals from the electronic device 110 via the connecting assembly 130.

As described above, in the electronic device 100 of this embodiment, the display screen 120 is provided with a connection assembly 130, allowing the electronic device 110 to be connected to one side of the display screen 120 via the connection assembly 130. Furthermore, the display screen 120 can receive signals from the electronic device 110 via the connection assembly 130. Consequently, the electronic device 110 of the electronic device 100 can serve as the computing core, while the display screen 120 is primarily used for displaying a large-scale image. Consequently, the user can use the electronic device 110 as a portable device alone, while using the display screen 120 as an expansion screen for the electronic device 110. Furthermore, the electronic device 110 is magnetically connected to the connection assembly 130 and can be pivoted to change its relative angle with respect to the display screen 120. This allows the user to easily attach and detach the electronic device 110 and adjust the angle of the electronic device 110 as needed.

FIG6 shows the electronic device of FIG5 installed on a keyboard device. FIG7 is a perspective view of the keyboard device of FIG6 . Referring to FIG6 and FIG7 , the electronic device 100 (shown in FIG1B ) of this embodiment further includes a keyboard device 140. The keyboard device 140 includes a keyboard body 142 and a second connecting plate 144 pivotally connected to each other. The electronic device 110 is adapted to be coupled to the second connecting plate 144 as shown in FIG6 . The keyboard device 140 can, for example, wirelessly connect to the electronic device 110 to transmit signals thereto. Alternatively, the keyboard device 140 can transmit signals to the electronic device 110 through a physical connection. Specifically, the keyboard device 140 has a third electrical connection portion 140a. When the electronic device 110 is coupled to the second connection plate 144 as shown in FIG6 , the first electrical connection portion 112 of the electronic device 110 and the third electrical connection portion 140a of the keyboard device 140 are electrically connected to each other. Furthermore, the second connection plate 144 can pivot relative to the keyboard body 142 to adjust the angle of the electronic device 110. The first electrical connection portion 112, the second electrical connection portion 132a, and the third electrical connection portion 140a are preferably spring-loaded connectors (POGO PIN) or Universal Serial Bus (USB), which support hot-swappable and plug-and-play connectivity.

In this embodiment, the second electrical connection portion 132a of the first connecting plate 132 of the connecting assembly 130 (shown in FIG. 3 ) is located between the geometric center C1 of the first connecting plate 132 and the pivot structure 134 (marked in FIG. 1B ). This places the second electrical connection portion 132a close to the edge 1321 of the first connecting plate 132 (at the pivot structure 134 ). Consequently, the first electrical connection portion 112 of the electronic device 110 (shown in FIG. 5 ) is correspondingly located close to the edge 1101 of the electronic device 110. Advantages of this connection configuration include minimizing the distance between the signal circuitry connecting the second electrical connection 132a and the display screen 120. Furthermore, the proximity of the second electrical connection 132a to the pivot structure reduces the likelihood of vibration and the risk of signal interruption during the pivoting of the connection assembly 130. Similarly, the third electrical connection 140a of the keyboard device 140 is correspondingly located (as shown in FIG. 7 ) between the geometric center C2 of the second connection plate 144 and the keyboard body 142, placing the third electrical connection 140a close to the keyboard body 142. Thus, the electronic device 110 can be easily connected to the third electrical connection portion 140a of the expanded keyboard device 140 via its first electrical connection portion 112. Specifically, because the third electrical connection portion 140a is close to the keyboard body 142 as described above, the third electrical connection portion 140a also has the advantages of minimizing signal circuit distance and ensuring high connection stability.

Figures 8A to 8E are top views of the hinge structure of Figure 1A during operation, with the states of Figures 8A, 8D, and 8E corresponding to the states of Figures 2A, 2B, and 2C, respectively. Referring to Figures 8A to 8E, the hinge structure 134 of this embodiment is, for example, a dual-axle structure comprising a body 1341 and parallel first and second hinges 1342 and 1343. The body 1341 and the display screen 120 are pivotally connected via the first hinge 1342, while the body 1341 and the first connecting plate 132 are pivotally connected via the second hinge 1343. Through the aforementioned dual-axis design, the first connecting plate 132 can be rotated at a large angle relative to the display screen 120 through the movement of the pivot structure 134.

Specifically, in this embodiment, the first pivot 1342 and the second pivot 1343 are, for example, decoupled from each other, and a first torque on the first pivot 1342 is set greater than a second torque on the second pivot 1343. Consequently, when the first connecting plate 132 rotates from the position shown in FIG8A relative to the display screen 120 to the position shown in FIG8D (shown as a rotation from 0 degrees to 180 degrees), the second pivot 1343, which has a smaller torque, pivots. Subsequently, when the first connecting plate 132 rotates from the position shown in FIG8D relative to the display screen 120 to the position shown in FIG8E (shown as a rotation from 180 degrees to 225 degrees), the first pivot 1342, which has a larger torque, pivots.

Continuing from the above, the magnetic attraction between the first connecting plate 132 and the first back surface 110b of the electronic device 110 (shown in Figures 2A to 2C ) of this embodiment is configured to vary according to the angle between the second back surface 120b of the display screen 120 and the first connecting plate 132. Specifically, when the angle between the second back surface 120b of the display screen 120 and the first connecting plate 132 is less than 180 degrees (i.e., the state between Figures 8A to 8D ), a first magnetic attraction greater than the second torsional force exists between the first connecting plate 132 and the first back surface 110b of the electronic device 110 (shown in Figures 2A to 2C ), thereby preventing the electronic device 110 from being separated from the first connecting plate 132 due to a user-applied turning force. When the angle between the second back surface 120b of the display screen 120 and the first connecting plate 132 is greater than 180 degrees and less than 225 degrees (i.e., the state between Figures 8D and 8E), a second magnetic attraction force greater than the first torque is generated between the first connecting plate 132 and the first back surface 110b of the electronic device 110 (shown in Figures 2A to 2C). This prevents the electronic device 110 from being separated from the first connecting plate 132 due to a turning force applied by the user. When the angle between the second rear surface 120b of the display screen 120 and the first connecting plate 132 is greater than 225 degrees, a third magnetic attraction force, less than the first torque, is generated between the first connecting plate 132 and the first rear surface 110b of the electronic device 110 (shown in Figures 2A to 2C). This facilitates the electronic device 110's detachment from the first connecting plate 132, preventing the user's tilting force from being continuously transmitted to the first connecting plate 132, the hinge structure 134, and/or the display screen 120 after the tilting angle approaches its limit, potentially causing structural damage.

In another embodiment, the first pivot 1342 and the second pivot 1343 can be designed to be interconnected and to have a torsional force. Specifically, the first pivot 1342 and the second pivot 1343 can be connected to each other via a gear set or other type of linkage mechanism. This allows the first pivot 1342 and the second pivot 1343 to pivot synchronously at a predetermined pivot angle ratio throughout the entire rotation process of the first connecting plate 132 relative to the display screen 120.

Continuing from the above, the magnetic attraction between the first connecting plate 132 and the first back surface 110b of the electronic device 110 (shown in FIG. 2A to FIG. 2C ) can also be configured to vary with the angle between the second back surface 120b of the display screen 120 and the first connecting plate 132 . Specifically, when the angle between the second back surface 120b of the display screen 120 and the first connecting plate 132 is less than 180 degrees, a first magnetic attraction force greater than the torsional force exists between the first connecting plate 132 and the first back surface 110b of the electronic device 110. Furthermore, when the angle between the second back surface 120b of the display screen 120 and the first connecting plate 132 is greater than 180 degrees but less than 225 degrees, a second magnetic attraction force greater than the first magnetic attraction exists between the first connecting plate 132 and the first back surface 110b of the electronic device 110. This prevents the electronic device 110 from being separated from the first connecting plate 132 due to a user-applied turning force. When the angle between the second rear surface 120b of the display screen 120 and the first connecting plate 132 is greater than 225 degrees, a third magnetic attraction force, less than the torsional force, is generated between the first connecting plate 132 and the first rear surface 110b of the electronic device 110. This allows the electronic device 110 to easily detach from the first connecting plate 132. This prevents the user-applied turning force on the electronic device 110 from being continuously transmitted to the first connecting plate 132, the hinge structure 134, and/or the display screen 120 after the turning angle approaches its limit, potentially causing structural damage.

In the above embodiment, the magnetic attraction between the first connecting plate 132 and the first back surface 110b of the electronic device 110 (shown in Figures 2A to 2C) is provided by, for example, an electromagnet disposed on at least one of the first connecting plate 132 and the electronic device 110. This electromagnet allows the first connecting plate 132 to be magnetically attracted to the first back surface 110b of the electronic device 110. The magnetic force of the electromagnet is adjustable, allowing the magnetic attraction to be varied as described above. More specifically, the electronic device 100 may further include a motion sensor and an electromagnet controller. The motion sensing element may include an accelerometer and/or a gyroscope, disposed on at least one of the first connecting plate 132 and the pivot structure 134 to sense the rotation angle and direction of the first connecting plate 132 relative to the display screen 120. The electromagnetic controller is disposed on the display screen 120 and is adapted to adjust the magnetic force of the electromagnetic controller based on the rotation angle and direction.

Furthermore, in the aforementioned embodiment, the first connecting plate 132 and the second rear surface 120b of the display screen 120 are also adapted to be magnetically attracted to each other, thereby maintaining the first connecting plate 132 in the closed position shown in FIG1A . Furthermore, the magnetic attraction between the first connecting plate 132 and the second rear surface 120b of the display screen 120 is, for example, weaker than the magnetic attraction between the first connecting plate 132 and the first rear surface 110b of the electronic device 110. This allows a user to unfold the electronic device 110 and the first connecting plate 132 together from the second rear surface 120b of the display screen 120 without removing the electronic device 110 from the first connecting plate 132.

In some embodiments, the display screen 120 and the first connecting plate 132 may each be provided with multiple magnets to provide a magnetic attraction force with a specific magnetic strength distribution. This is illustrated below with an example.

Figure 9A is a partial schematic diagram of an electronic device according to another embodiment of the present invention. In the embodiment shown in Figure 9A , the first connecting plate 132 has multiple connecting plate magnetic elements M1, and the second rear surface 120b of the display screen 120 has multiple display screen magnetic elements M2. The first connecting plate 132 is adapted to be attached to the second rear surface 120b of the display screen 120 via the magnetic attraction between the connecting plate magnetic elements M1 and the display screen magnetic elements M2.

In the embodiment of FIG9A , the second electrical connection portion 132a is used as a dividing line to distinguish the number of connection plate magnetic elements M1. Specifically, the number of connection plate magnetic elements M1 located above the second electrical connection portion 132a is greater than the number of connection plate magnetic elements M1 located below the second electrical connection portion 132a. Furthermore, the farther away from the pivot structure (i.e., the edge 1321 of the first connection plate 132), the fewer these connection plate magnetic elements M1 are. Similarly, the farther away from the pivot structure (i.e., the edge 1321 of the first connection plate 132), the fewer the display screen magnetic elements M2 are. This allows the user to easily apply force to the electronic device 110 (shown in FIG. 4 ) from the lower left side of the first connecting plate 132 and remove the electronic device 110. Furthermore, the number of display screen magnetic elements M2 is, for example, less than the number of connecting plate magnetic elements M1, allowing the user to unfold the electronic device 110 and the first connecting plate 132 together from the second rear surface 120b of the display screen 120 without removing the electronic device 110 from the first connecting plate 132.

Figure 9B is a partial schematic diagram of an electronic device according to another embodiment of the present invention. The embodiment shown in Figure 9B differs from the embodiment shown in Figure 9A in that the connection plate magnetic elements M1 and the display screen magnetic elements M2 of the embodiment shown in Figure 9A are respectively arranged in an inverted trapezoidal pattern, while the connection plate magnetic elements M1 and the display screen magnetic elements M2 of the embodiment shown in Figure 9B are respectively arranged in a triangular pattern. The remaining configuration and operation of the embodiment shown in Figure 9B are similar to those of the embodiment shown in Figure 9A and will not be further described here.

Figure 9C is a partial schematic diagram of an electronic device according to another embodiment of the present invention. In the embodiment shown in Figure 9C , the first connecting plate 132 has multiple connecting plate magnetic elements M1', M1", and the second rear surface 120b of the display screen 120 has multiple display screen magnetic elements M2', M2", The first connecting plate 132 is adapted to be attached to the second rear surface 120b of the display screen 120 by the magnetic attraction between these connecting plate magnetic elements M1', M1" and these display screen magnetic elements M2', M2".

Furthermore, the magnetic strength of the connecting plate magnetic element M1’ is greater than the magnetic strength of the connecting plate magnetic element M1”. Thus, the magnetic strength of the portion of the connecting plate magnetic elements located above the second electrical connection portion 132a is greater than the magnetic strength of the portion of the connecting plate magnetic elements located below the second electrical connection portion 132a, and the magnetic strength of these connecting plate magnetic elements is smaller at a position farther away from the pivot structure (i.e., the edge 1321 of the first connecting plate 132). Similarly, the magnetic strength of the display screen magnetic element M2’ is greater than the magnetic strength of the display screen magnetic element M2”. Thus, the magnetic strength of these display screen magnetic elements is smaller at a position farther away from the pivot structure (i.e., the edge 1321 of the first connecting plate 132). This allows the user to easily remove the electronic device 110 by applying force to the lower left side of the first connecting plate 132 (shown in Figure 4). Furthermore, the number of display screen magnetic elements M2' and M2" is, for example, less than the number of connecting plate magnetic elements M1' and M1" to allow the user to unfold the electronic device 110 and the first connecting plate 132 together from the second rear surface 120b of the display screen 120 without removing the electronic device 110 from the first connecting plate 132.

Figure 9D is a partial schematic diagram of an electronic device according to another embodiment of the present invention. The embodiment shown in Figure 9D differs from the embodiment shown in Figure 9C in that the connection plate magnetic elements M1' and the display screen magnetic elements M2' in the embodiment shown in Figure 9C are respectively arranged in an inverted trapezoidal pattern, while the connection plate magnetic elements M1' and the display screen magnetic elements M2' in the embodiment shown in Figure 9D are respectively arranged in a triangular pattern. The remaining configuration and operation of the embodiment shown in Figure 9D are similar to those of the embodiment shown in Figure 9C and will not be further described here.

It should be noted that the common feature of Figures 9A through 9D is that magnetic elements are disposed around the second electrical connection portion 132a to ensure a stable electrical connection between the electronic device 110 and the first connection plate 132. Furthermore, in some embodiments, the first connection plate 132 may be equipped with a movable magnet or metal component to adjust the strength of the magnetic attraction between it and the electronic device 110, replacing the previously described method of using an electromagnetic controller to adjust the magnetic force. This is illustrated below with examples.

Figure 10 is a schematic diagram of an electronic device according to another embodiment of the present invention. Figures 11A and 11B are schematic diagrams corresponding to the operation of the first connecting plate of the electronic device shown in Figure 10 . In the embodiment shown in Figures 10 and 11B , the connecting assembly 130' further includes a movable member 136A, which is movably disposed on the first connecting plate 132. The first connecting plate 132 is adapted to be magnetically attracted to the first back surface 110b of the electronic device 110 via the movable member 136A. Specifically, the first back surface 110b of the electronic device 110 has an electronic device magnetic element M3, the first connecting plate 132 has a connecting plate magnetic element M4, and the movable member 136A has movable member magnetic elements M5 and M5'. By arranging the polarity, the connecting plate magnetic element M4 and the movable element magnetic element M5 are adapted to magnetically attract the electronic device magnetic element M3, while the movable element magnetic element M5' is adapted to magnetically repel the electronic device magnetic element M3.

Movable element 136A is adapted to move along first connecting plate 132 between the positions shown in FIG. 11A and FIG. 11B as the display screen 120 and first connecting plate 132 pivot relative to each other, thereby aligning or misaligning the electronic device magnetic element M3 and the movable element magnetic element M5'. When movable element 136A is in the position shown in FIG. 11A , the electronic device magnetic element M3 and the movable element magnetic element M5' are misaligned, resulting in a stronger magnetic attraction between first connecting plate 132 and electronic device 110. When movable element 136A is in the position shown in FIG. 11B , the electronic device magnetic element M3 and the movable element magnetic element M5' are aligned, resulting in a weaker magnetic attraction between first connecting plate 132 and electronic device 110.

Figure 12 is a schematic diagram of an electronic device according to another embodiment of the present invention. Figures 13A and 13B are schematic diagrams of the operation of the first connecting plate of the electronic device shown in Figure 12 . In the embodiment shown in Figures 12 and 13B , the first back surface 110b of the electronic device 110 has a plurality of electronic device magnetic elements M3'. A movable element 136B is movably disposed on the first connecting plate 132. The movable element 136B is a magnetically attracted metal member adapted to move along the first connecting plate 132 between a first position shown in Figure 13A and a second position shown in Figure 13B . The movable element 136B in the first position corresponds to a first number of the electronic device's magnetic components M3'. The movable element 136B in the second position corresponds to a second number of the electronic device's magnetic components M3'. The first number is different from the second number, thereby varying the magnetic attraction between the first connecting plate 132 and the electronic device 110.

Figures 14A and 14B illustrate the movable member of Figures 13A and 13B being driven by a linkage mechanism. As shown in Figures 14A and 14B, movable member 136B of this embodiment can be driven by a linkage mechanism 138 connected between pivot structure 134 and movable member 136B. Movable member 136B of Figures 11A and 11B can also be driven by a similar mechanism. In other embodiments, movable members 136A and 136B can be connected to pivot structure 134 using other appropriate methods, and the present invention is not limited thereto.

Figures 15A to 15C illustrate how the first electrical connection portion of the electronic device of Figure 5 is coupled to the second electrical connection portion of Figure 3. Referring to Figures 15A to 15C, the first electrical connection portion 112 and the second electrical connection portion 132a of this embodiment are, for example, in the form of pogo pins. Specifically, a magnetic element 114 is provided within the electronic device 110 adjacent to the first electrical connection portion 112, and the second electrical connection portion 132a is movably disposed on the first connection plate 132 and includes a magnetically attracted material. When the electronic device 110 approaches the first connection plate 132 as shown in Figures 15A to 15C, the second electrical connection portion 132a approaches and couples to the first electrical connection portion 112 by the magnetic attraction of the magnetic element 114, as shown in Figure 15C. When the electronic device 110 moves away from the first connecting plate 132 as shown in FIG. 15C to FIG. 15A , the second electrical connection portion 132a retracts and returns to its original position as shown in FIG. 15A .

Figures 16A to 16C illustrate the addition of a counterweight unit to the display screen of Figure 1A and its function. Referring to Figures 16A to 16C , the electronic device 100 of this embodiment further includes a counterweight unit 150. Counterweight unit 150 is movably disposed along a track 160 on the display screen 120. Counterweight unit 150 can be moved to the positions shown in Figures 16B and 16C , positioning counterweight unit 150 and connection assembly 130 on opposite sides of the geometric center C3 of display screen 120. Accordingly, when the first connecting plate 132 of the connecting assembly 130 is unfolded as shown in FIG16B and when the electronic device 110 is mounted on the first connecting plate 132 as shown in FIG16C , the counterweight unit 150 can balance the weight of the entire device, preventing the device from tilting or falling.

Furthermore, a motion sensor can be disposed on at least one of the first connecting plate 132 and the pivot structure 134 to sense the tilt angle and direction of the first connecting plate 132 relative to the display screen 120. A counterweight unit controller can also be disposed on the display screen 120 to adjust the position of the counterweight unit 150 based on the tilt angle and direction of the first connecting plate 132 relative to the display screen 120, thereby achieving a well-balanced weight state. For example, in the state shown in FIG16B , the product of the weight F of the counterweight unit 150 and its moment arm r2 relative to the geometric center C3 is equal to the product of the weight F1 of the first connecting plate 132 and its moment arm r1 relative to the geometric center C3. Similarly, in the state shown in FIG16C , the product of the weight F of the counterweight unit 150 and its moment arm r4 relative to the geometric center C3 is equal to the product of the total weight F2 of the first connecting plate 132 and the electronic device 110 and their moment arms r1 + r3 relative to the geometric center C3.

Figures 17A to 17C illustrate another embodiment of the present invention, including a display screen with an additional counterweight unit and its function. The configuration and function of the counterweight unit 150, counterweight unit controller, and motion sensing element in the embodiment shown in Figures 17A to 17C are generally similar to those in the embodiment shown in Figures 16A to 16C. The primary difference between the two is that the embodiment shown in Figures 17A to 17C incorporates a motor 170 on the display screen 120. Motor 170 is coupled to the counterweight unit controller, and a transmission assembly 180 connects motor 170 and counterweight unit 150. The counterweight unit controller controls motor 170 to move counterweight unit 150 via transmission assembly 180. In this embodiment, transmission assembly 180 is, for example, a conveyor belt.

Figures 18A through 18C illustrate another embodiment of the present invention, including a display screen with an additional counterweight unit and its function. The configuration and function of the counterweight unit 150, counterweight unit controller, motion sensor, and motor 170 in the embodiment shown in Figures 18A through 18C are generally similar to those in the embodiment shown in Figures 17A through 17C. The primary difference between the two is that the transmission assembly 180' in the embodiment shown in Figures 18A through 18C is a lead screw.

Figure 19 is a schematic diagram of an electronic device according to another embodiment of the present invention. The primary difference between the embodiment shown in Figure 19 and the aforementioned embodiments is that connection assemblies 130 are provided on both sides of the display screen 120. Users can install two electronic devices 110 on the first connection plates 132 of the two connection assemblies 130, respectively. In this embodiment, the first electrical connection portion 112 of each electronic device 110 is located adjacent to a long side of the electronic device 110, while the camera 116 of each electronic device 110 is located adjacent to a short side of the electronic device 110. Therefore, when the two electronic devices 110 are mounted on the first connecting plates 132 of the two connecting assemblies 130, the camera 116 of the left electronic device 110 is located near the top of the entire device, while the camera 116 of the right electronic device 110 is located near the bottom of the entire device. While the present invention does not limit the location of the first electrical connection portion 112 and the camera 116, the following diagrams provide an example to illustrate this.

Figures 20A to 20D are schematic diagrams of electronic devices according to other embodiments of the present invention. The primary difference between the embodiment shown in Figure 20A and the embodiment shown in Figure 19 is that the first electrical connection portion 112 of each electronic device 110 in Figure 20A is located adjacent to a long side of the electronic device 110, while the camera 116 of each electronic device 110 is located adjacent to another long side of the electronic device 110. Consequently, when two electronic devices 110 are mounted on the first connection plates 132 of two connection assemblies 130, the cameras 116 of both electronic devices 110 are located adjacent to the horizontal outer sides of the entire device.

The main difference between the embodiment shown in Figures 20B and 20C and the embodiment shown in Figure 19 is that the first electrical connection portion 112 of each electronic device 110 in Figures 20B and 20C is located at the geometric center of the electronic device 110, and the camera 116 of each electronic device 110 is adjacent to a short side of the electronic device 110. Therefore, when two electronic devices 110 are mounted on the first connection plates 132 of two connection assemblies 130, the cameras 116 of both electronic devices 110 can be positioned adjacent to the top of the entire device, as shown in Figure 20B, or adjacent to the bottom of the entire device, as shown in Figure 20C.

The primary difference between the embodiment shown in FIG20D and the embodiment shown in FIG19 is that the first electrical connection portion 112 of each electronic device 110 in FIG20D is located at the geometric center of the electronic device 110, and the camera 116 of each electronic device 110 is adjacent to a long side of the electronic device 110. Therefore, when two electronic devices 110 are mounted on the first connection plates 132 of two connection assemblies 130, the cameras 116 of both electronic devices 110 are adjacent to the display screen 120.

Figure 21 is a partial structural diagram of an electronic device according to another embodiment of the present invention. Figure 22 is a schematic diagram of the hinge structure and locking mechanism of Figure 21 . Referring to Figures 21 and 22 , the electronic device of this embodiment further includes a locking mechanism 190 , which is disposed on the first connecting plate 132 and is adapted to lock the electronic device 110 to the first connecting plate 132 . Specifically, the locking mechanism 190 activates as the first connecting plate 132 is rotated relative to the display screen 120. When the angle between the second rear surface 120b of the display screen 120 and the first connecting plate 132 is less than 180 degrees, the locking mechanism 190 locks the electronic device 110 to the first connecting plate 132. When the angle between the second rear surface 120b of the display screen 120 and the first connecting plate 132 is greater than 180 degrees, the locking mechanism 190 releases the electronic device 110.

Specifically, the locking mechanism 190 of this embodiment includes a locking assembly 192, a linkage mechanism 194, and an elastic member 196. The locking assembly 192 is movably disposed on the first connecting plate 132 and includes two hooks 1921, with the elastic member 196 connected between the two hooks 1921. The linkage mechanism 194 is coupled to the pivot structure 134 and includes a connecting rod 1941 and a trapezoidal plate 1942. The connecting rod 1941 is connected between the trapezoidal plate 1942 and the pivot structure 134. The pivot structure 134 is adapted to drive the locking assembly 192 to move via the linkage mechanism 194 to lock or release the electronic device 110.

Figures 23A and 23B illustrate the locking mechanism of Figure 22 . Specifically, the two hooks 1921 are adapted to engage with the edges of the opening 118 of the electronic device 110, as shown in Figure 23A , via the elastic force of the elastic member 196 . As the pivot structure 134 pivots, the connecting rod 1941 drives the trapezoidal plate 1942 toward the space between the two hooks 1921 . The trapezoidal plate 1942 resists the elastic force of the elastic member 196 and drives the two hooks 1921 away from each other, releasing the hooks 1921, as shown in Figure 23B .

In summary, in the electronic device of the present invention, the display screen is equipped with a connection assembly, allowing the electronic device to be connected to the display screen via the connection assembly. Furthermore, the display screen can receive signals from the electronic device via the connection assembly. Consequently, the electronic device of the electronic device can serve as the computing core, while the display screen is primarily used for displaying large-scale images. Consequently, the user can use the electronic device as a portable device alone, while using the display screen as an expansion screen for the electronic device. Furthermore, the electronic device is magnetically connected to the connection assembly, and the pivoting motion of the connection assembly allows the relative angle between the electronic device and the display screen to be changed, making it easy for the user to attach and detach the electronic device and adjust the angle of the electronic device as needed. Furthermore, the second electrical connection portion of the first connection plate of the connection assembly is located between the geometric center of the first connection plate and the pivot structure, placing the second electrical connection portion close to the edge of the first connection plate (the pivot structure). Consequently, the first electrical connection portion of the electronic device is correspondingly close to the edge of the electronic device, making it easier for the electronic device to connect to an expanded keyboard device via its first electrical connection portion.
