Description

Electronic device

Technical Field

The present invention relates to electronic devices, and more particularly to an electronic device with a flexible screen.

Background

Since the curved display can provide a user with a surrounding view to obtain a visual immersion, manufacturers have been pushing notebook computers with curved displays. The common curved display comprises a casing and a curved display screen, wherein the curved display screen is arranged in the casing, and the curvature of the curved display screen is fixed. In order to match the geometric outline of the curved display screen, the side of the casing facing the machine body is mostly designed into an arc shape, and the design causes the volume, thickness and weight of the casing to be increased. In addition, when the curved display is closed on the machine body, a large gap exists between the machine shell and the machine body. Therefore, in many of the notebook computers with curved displays on the market, the notebook computers are too heavy and have insufficient structural strength.

Disclosure of Invention

The invention provides an electronic device which can meet the design requirement of light and thin products.

The invention provides an electronic device, which comprises a first machine body, a second machine body and a magnetic force mechanism. The first body includes a driving part. The second body is pivoted with the first body. The second body comprises a shell, a flexible screen and a supporting mechanism. The supporting mechanism is movably arranged in the shell, and the flexible screen is attached to the supporting mechanism. The magnetic force mechanism comprises a sliding rod, a first magnet, a second magnet and a third magnet. The slide bar is arranged on the shell in a sliding way. The first magnet is arranged on the sliding rod and faces the supporting mechanism. The second magnet and the third magnet are arranged on the supporting mechanism and face the sliding rod. The sliding rod is provided with a driven end exposed out of the shell, and the driven end is abutted against the driving part. The first magnet is opposite to the second magnet to generate magnetic attraction force to the second magnet, or the first magnet is opposite to the third magnet to generate magnetic repulsion force to the third magnet.

Based on the above, the electronic device of the present invention can generate a magnetic attraction force to the flexible screen by the magnetic mechanism to make the flexible screen flat, or generate a magnetic repulsion force to the flexible screen by the magnetic mechanism to make the flexible screen bend. Because the curvature of the flexible screen is not fixed, the casing of the second body is not required to be designed into an arc structure by matching with the curvature of the flexible screen, so as to meet the design requirement of light and thin products. When the second body is closed on the first body, the second body can be tightly attached to the first body, so that the problems of excessively thick overall thickness, insufficient structural strength and the like of the electronic device cannot be derived. On the other hand, the acting force applied to the flexible screen by the magnetic force mechanism can be converted through the relative rotation of the second body and the first body. Therefore, the electronic device is convenient for users to operate.

In order to make the above features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1 and fig. 5, in the present embodiment, the electronic device 100 may be a notebook computer, wherein the electronic device 100 includes a first body 110 and a second body 120, and the second body 120 is pivoted to the first body 110. Fig. 1 shows a state in which the second body 120 is closed to the first body 110, and fig. 5 shows a state in which the second body 120 is unfolded with respect to the first body 110.

In detail, the first body 110 has an operation processing function, and is provided with a keyboard set 111 and a touch pad 112. The second body 120 has a display function, wherein the second body 120 includes a housing 121 and a flexible screen 122, and the flexible screen 122 is disposed in the housing 121. The casing 121 has a window 121a for a user to view the display surface of the flexible screen 122 through the window 121 a. As shown in fig. 5 and 6, the display surface of the flexible screen 122 is curved, so as to provide a surrounding view for the user and to make the user feel visually immersed. As shown in fig. 1 and 2, when the second body 120 is closed on the first body 110, the flexible screen 122 remains flat and unbent. In other words, the curvature of the flexible screen 122 may change with the state of the electronic device 100.

Since the curvature of the flexible screen 122 is not fixed, the casing 121 is not required to be designed into an arc structure in cooperation with the curvature of the flexible screen 122, so as to meet the design requirement of light and thin products. When the second body 120 is closed on the first body 110, the second body 120 can be tightly attached to the first body 110, so that the problems of excessively thick overall thickness, insufficient structural strength, and the like of the electronic device 100 are not derived. Specifically, as long as the internal space of the casing 121 is sufficient to bend the stressed flexible screen 122, and structural interference is not caused to the flexible screen 122, the casing 121 can have a light, thin and compact design.

Referring to fig. 2 to 4, the second body 120 further includes a supporting mechanism 123 movably disposed in the housing 121, wherein the flexible screen 122 is attached to the supporting mechanism 123, and a curvature of the flexible screen 122 can be changed according to a state of the electronic device 100. As shown in fig. 3, the supporting mechanism 123 is in a flat plate structure, and the flexible screen 122 is flattened to conform to the geometric outline of the supporting mechanism 123. As shown in fig. 6, the supporting mechanism 123 is in an arc-shaped structure, and the flexible screen 122 is curved following the geometric outline of the supporting mechanism 123.

Referring to fig. 1 to 4, in the present embodiment, the electronic device 100 further includes a first magnetic mechanism 130a and a second magnetic mechanism 130b disposed in the housing 121, wherein the composition and design principle of the first magnetic mechanism 130a and the second magnetic mechanism 130b are the same, and the first magnetic mechanism 130a and the second magnetic mechanism 130b are disposed on the left side and the right side of the supporting mechanism 123. On the other hand, the first body 110 includes a first driving portion 113a and a second driving portion 113b, wherein the first driving portion 113a and the second driving portion 113b have the same structural design, and the first driving portion 113a and the second driving portion 113b protrude from the input operation surface 114 (i.e. the surface where the keyboard set 111 and the touch pad 112 are located). The first driving part 113a is disposed corresponding to the first magnetic force mechanism 130a, and the second driving part 113b is disposed corresponding to the second magnetic force mechanism 130 b. In other embodiments, the combination of the first magnetic mechanism 130a and the first driving portion 113a and the combination of the second magnetic mechanism 130b and the second driving portion 113b may be alternatively arranged.

Since the composition of the first magnetic mechanism 130a and the second magnetic mechanism 130b is the same as the design principle, and the structural design of the first driving portion 113a and the second driving portion 113b is the same. The combination of the first magnetic mechanism 130a and the first driving portion 113a is set forth below.

In the present embodiment, the first magnetic mechanism 130a includes a sliding rod 131, a first magnet 132, a second magnet 133, and a third magnet 134, wherein the sliding rod 131 is slidably disposed on the housing 121, and the sliding rod 131 is configured to slide along a first sliding direction D1 relative to the housing 121. The first magnet 132 is disposed on the sliding rod 131 and faces the supporting mechanism 123 to slide along with the sliding rod 131. The second magnet 133 and the third magnet 134 are disposed on the supporting mechanism 123 and face the sliding rod 131, and in the process that the first magnet 132 slides along with the sliding rod 131, the first magnet 132 can slide through the side of the second magnet 133 or the third magnet 134. As shown in fig. 4, the first magnet 132 slides to the side of the second magnet 133 and faces the second magnet 133, and as shown in fig. 7, the first magnet 132 slides to the side of the third magnet 134 and faces the third magnet 134.

As shown in fig. 1 and 5, the sliding rod 131 has a driven end 131a exposed out of the housing 121, and the driven end 131a abuts against the first driving portion 113a. In the process of the electronic device 100 moving from the first state to the second state, the first driving portion 113a pushes the driven end 131a into the housing 121, so that the sliding rod 131 slides relative to the housing 121. When the first magnet 132 faces the third magnet 134, the first magnet 132 generates a magnetic repulsive force to the third magnet 134, as shown in fig. 7. At this time, the first magnetic mechanism 130a and the second magnetic mechanism 130b apply magnetic repulsion force to the left end and the right end of the supporting mechanism 123, respectively, so that the left end of the supporting mechanism 123 moves to the right and the right end of the supporting mechanism 123 moves to the left, thereby driving the supporting mechanism 123 to shrink and bend, and the flexible screen 122 is driven by the supporting mechanism 123 to bend, as shown in fig. 6 and fig. 7.

As shown in fig. 1 and fig. 5, in the process of the electronic device 100 moving from the second state to the first state, the driven end 131a moves out of the housing 121, so that the sliding rod 131 slides relative to the housing 121. When the first magnet 132 faces the second magnet 133, the first magnet 132 generates a magnetic attraction force to the second magnet 133, as shown in fig. 4. At this time, the first magnetic mechanism 130a and the second magnetic mechanism 130b apply magnetic attraction to the left end and the right end of the supporting mechanism 123 respectively, so that the left end of the supporting mechanism 123 moves left and the right end of the supporting mechanism 123 moves right, thereby driving the supporting mechanism 123 to be tensioned and spread, and the flexible screen 122 is tensioned and spread under the driving of the supporting mechanism 123, as shown in fig. 3 and fig. 4.

That is, the force applied to the flexible screen 122 by the first magnetic force mechanism 130a and the second magnetic force mechanism 130b can be converted by the relative rotation of the second body 120 and the first body 110. Therefore, the operation of the electronic device 100 is very convenient for the user.

Further, during the rotation of the second body 120 relative to the first body 110, the sliding rod 131 abuts against different sections on the first driving portion 113a, and the driven end 131a is pushed into the housing 121 to different degrees based on the change of the geometric profile of the first driving portion 113 a. The first driving portion 113a has a straight line segment 115, a turning segment 116 and a cam segment 117, wherein the straight line segment 115 is connected to the input operation surface 114, and the turning segment 116 is located between the straight line segment 115 and the cam segment 117. When the driven end 131a of the slide bar 131 abuts against the linear section 115, the driven end 131a is not pushed into the housing 121, and the first magnet 132 faces the second magnet 133 without sliding the slide bar 131 relative to the housing 121, as shown in fig. 1 and 4. As the driven end 131a of the slide bar 131 moves through the turn section 116, the driven end 131a begins to be pushed into the housing 121, causing the slide bar 131 to slide relative to the housing 121. When the driven end 131a of the slide bar 131 moves to (or abuts against) the cam section 117, the first magnet 132 faces the third magnet 134, as shown in fig. 5 and 7.

In the process of the electronic device 100 moving from the second state to the first state, in order to ensure that the first magnet 132 slides along the sliding rod 131 and faces the second magnet 133 again, the magnetic attraction force generated by the first magnet 132 to the second magnet 133 may be designed to be greater than the magnetic repulsion force generated by the first magnet 132 to the third magnet 134, so as to drive the sliding rod 131 to reset. The above-described magnetic force design does not affect the facing state of the first magnet 132 and the third magnet 134, based on the abutting relationship between the slide bar 131 and the first driving portion 113 a.

As shown in fig. 1 and 5, the housing 121 has a side 121b facing the first driving portion 113a and the second driving portion 113b, and a pivot portion 121c protruding from the side 121 b. The electronic device 100 further includes a rotation shaft 140, wherein the pivot portion 121c is located between the first driving portion 113a and the second driving portion 113b, and the rotation shaft 140 is inserted into the first driving portion 113a, the second driving portion 113b, and the pivot portion 121c. On the other hand, the housing 121 also has openings 121d (two shown) at the side 121b for the removal or movement of the driven end 131a of the slide bar 131 into or out of the housing 121.

As shown in fig. 4 and fig. 7, the first magnetic force mechanism 130a is illustrated, and the number of the first magnets 132 may be plural and arranged on the sliding rod 131 along the first sliding direction D1. The number of the second magnets 133 and the number of the third magnets 134 may be plural, wherein the second magnets 133 and the third magnets 134 are staggered along the first sliding direction D1, and the number of the first magnets 132, the number of the second magnets 133, and the number of the third magnets 134 are equal. For example, a second magnet 133 and a third magnet 134 adjacent to each other may form a magnet set 135, and each magnet set 135 is disposed corresponding to one first magnet 132. As shown in fig. 1 and 4, the second magnet 133 is located between the driving portion 113a and the third magnet 134 in the first sliding direction D1 for each of the magnet groups 135.

Referring to fig. 2 to 4, in the present embodiment, the supporting mechanism 123 includes at least two side supporting blocks 123a, two movable rods 123b and a plurality of middle supporting blocks 123c, wherein each side supporting block 123a is provided with at least one set of magnet groups 135 (including a second magnet 133 and a third magnet 134), and each movable rod 123b passes through one side supporting block 123a and is slidably disposed on the casing 121. Each movable rod 123b is configured to slide along the second sliding direction D2 relative to the casing 121, and the first sliding direction D1 is perpendicular to the second sliding direction D2.

As shown in fig. 3 and 4, the supporting mechanism 123 is tensioned and spread out, and the first distance L1 is maintained between the two movable rods 123 b. As shown in fig. 6 and 7, the supporting mechanism 123 is retracted and bent, and the second distance L2 is maintained between the two movable rods 123 b. During the transition of the electronic device 100 from the first state to the second state, the two movable rods 123b slide close to each other. On the other hand, during the transition of the electronic device 100 from the second state to the first state, the two movable rods 123b slide away from each other. Thus, the first distance L1 is greater than the second distance L2.

On the other hand, the intermediate support blocks 123c are juxtaposed between the two side support blocks 123a, wherein the intermediate support blocks 123c are connected to each other, and at least two of the intermediate support blocks 123c are respectively connected to the two side support blocks 123a. The adjacent two intermediate support blocks 123c have a degree of freedom of movement of relative rotation, and the adjacent one side support block 123a and one intermediate support block 123c have a degree of freedom of movement of relative rotation. In the process of the electronic device 100 moving from the first state to the second state, the two movable rods 123b slide close to each other, and the two side supporting blocks 123a are driven by the two movable rods 123b to push the middle supporting blocks 123c, so that the supporting mechanism 123 is retracted and bent. On the other hand, in the process of the electronic device 100 moving from the second state to the first state, the two movable rods 123b slide away from each other, and the two side supporting blocks 123a are driven by the two movable rods 123b to pull the middle supporting blocks 123c, so that the supporting mechanism 123 is tensioned and flattened.

In the present embodiment, the supporting mechanism 123 further includes a plurality of connection blocks 123d juxtaposed between the two side supporting blocks 123a, the adjacent two intermediate supporting blocks 123c are connected to each other through one connection block 123d, and the adjacent one side supporting block 123a and one intermediate supporting block 123c are connected to each other through one connection block 123 d. One intermediate support block 123c and one connection block 123d connected have a degree of freedom of movement of relative rotation, and one side support block 123a and one connection block 123d connected have a degree of freedom of movement of relative rotation.

For example, the number of the side supporting blocks 123a may be four, and any two of the side supporting blocks 123a are arranged in a group along the first sliding direction D1, and one movable rod 123b passes through the two side supporting blocks 123a arranged in the group. In the second sliding direction D2, a plurality of intermediate support blocks 123c are arranged in a row (row) between one side support block 123a and the other side support block 123a that are opposite to each other. Adjacent one side support block 123a and one intermediate support block 123c are connected to each other through one connection block 123d, and adjacent two intermediate support blocks 123c are connected to each other through one connection block 123 d. In the second sliding direction D2, the plurality of connection blocks 123D are arranged in a row (row). In the first sliding direction D1, the plurality of connection blocks 123D are sandwiched between one side support block 123a, the plurality of intermediate support blocks 123c, and the other side support block 123a of one of the rows (row) and one side support block 123a, the plurality of intermediate support blocks 123c, and the other side support block 123a of the other row (row).

In summary, the electronic device of the present invention can generate a magnetic attraction force to the flexible screen by the magnetic mechanism to make the flexible screen spread out, or generate a magnetic repulsion force to the flexible screen by the magnetic mechanism to make the flexible screen bend. Because the curvature of the flexible screen is not fixed, the casing of the second body is not required to be designed into an arc structure by matching with the curvature of the flexible screen, so as to meet the design requirement of light and thin products. When the second body is closed on the first body, the second body can be tightly attached to the first body, so that the problems of excessively thick overall thickness, insufficient structural strength and the like of the electronic device cannot be derived. The acting force applied to the flexible screen by the magnetic force mechanism can be converted through the relative rotation of the second body and the first body. Therefore, the electronic device is convenient for users to operate. On the other hand, the flexible screen after bending can provide the surrounding visual field for the user, so that the user can obtain visual immersion.

Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but rather may be modified or altered somewhat by those skilled in the art without departing from the spirit and scope of the present invention.
