Description

Electronic device

Technical Field

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

Background

Since the curved display can provide a user with a surrounding view to obtain a visual immersion, manufacturers have introduced notebook computers with curved displays. A conventional curved display includes a housing and a curved display screen, wherein the curved display screen is mounted in the housing, 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 to be arc-shaped, and the design causes the volume, thickness and weight of the casing to increase. In addition, when the curved display is closed on the body, a very large gap is formed between the housing and the body. Therefore, most of the notebook computers with curved displays on the market have problems of being too heavy and insufficient in structural strength.

Disclosure of Invention

The invention provides an electronic device which can meet the design requirement of lightening and thinning of a product.

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

In view of the above, the electronic device of the present invention can generate a magnetic attraction force to the flexible screen by the magnetic mechanism to unfold the flexible screen, or generate a magnetic repulsion force to the flexible screen by the magnetic mechanism to bend the flexible screen. Because the curvature of the flexible screen is not fixed, the housing of the second body is not required to be designed into an arc structure in accordance with the curvature of the flexible screen, so as to meet the design requirement of thinning the product. When the second body is closed to the first body, the second body can be tightly attached to the first body, so that the problems of over-thickness of the whole electronic device, insufficient structural strength and the like can be avoided. 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 of the invention is very convenient for the user to operate.

In order to make the aforementioned and other features and advantages of the 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 pivotally connected to the first body 110. Fig. 1 shows a state where the second body 120 is closed to the first body 110, and fig. 5 shows a state where the second body 120 is unfolded with respect to the first body 110.

Specifically, the first body 110 has an arithmetic processing function, and is provided with a keyboard group 111 and a touch pad (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 housing 121 has an opening region 121a for a user to view the display surface of the flexible screen 122 through the opening region 121 a. As shown in fig. 5 and 6, the display surface of the flexible screen 122 is curved to provide the user with a surrounding view and provide the user with a visual immersion feeling. As shown in fig. 1 and 2, when the second body 120 is closed to 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 housing 121 is designed to be an arc structure without matching the curvature of the flexible screen 122, so as to meet the design requirement of product lightness and thinness. When the second body 120 is closed to the first body 110, the second body 120 can be tightly attached to the first body 110, so that the problems of over-thickness and insufficient structural strength of the electronic device 100 are not caused. Specifically, as long as the internal space of the housing 121 is sufficient to bend the flexible screen 122 after being stressed and does not cause structural interference to the flexible screen 122, the housing 121 can be designed to be light, thin and compact.

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 the curvature of the flexible screen 122 can be changed along with the state change of the electronic device 100. As shown in fig. 3, the support mechanism 123 is generally a plate-like structure, and the flexible screen 122 is configured to conform to the geometric contour of the support mechanism 123. As shown in fig. 6, the support mechanism 123 is generally arcuate in shape, and the flexible screen 122 is curved to conform to the geometric profile of the support 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 located in the housing 121, wherein the first magnetic mechanism 130a and the second magnetic mechanism 130b have the same composition and design principle, and the first magnetic mechanism 130a and the second magnetic mechanism 130b are disposed on the left and right sides 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 group 111 and the touch pad 112 are located). The first driving portion 113a is disposed corresponding to the first magnetic mechanism 130a, and the second driving portion 113b is disposed corresponding to the second magnetic 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 disposed.

The first magnetic mechanism 130a and the second magnetic mechanism 130b have the same composition and design principle, and the first driving portion 113a and the second driving portion 113b have the same structural design. An explanation will be given below regarding a combination of the first magnetic mechanism 130a and the first driving portion 113 a.

In the embodiment, the first magnetic mechanism 130a includes a sliding bar 131, a first magnet 132, a second magnet 133 and a third magnet 134, wherein the sliding bar 131 is slidably disposed on the casing 121, and the sliding bar 131 is configured to slide along a first sliding direction D1 relative to the casing 121. The first magnet 132 is disposed on the sliding bar 131 and faces the supporting mechanism 123 to slide along with the sliding bar 131. The second magnet 133 and the third magnet 134 are disposed on the supporting mechanism 123 and face the sliding bar 131, and the first magnet 132 can slide past the second magnet 133 or the third magnet 134 during the process that the first magnet 132 slides along the sliding bar 131. 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 113 a. In the process of switching the electronic device 100 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 respectively apply magnetic repulsive force to the left end portion and the right end portion of the supporting mechanism 123, so that the left end portion of the supporting mechanism 123 moves to the right and the right end portion of the supporting mechanism 123 moves to the left, thereby driving the supporting mechanism 123 to contract and bend, and the flexible screen 122 is driven by the supporting mechanism 123 to bend, as shown in fig. 6 and 7.

As shown in fig. 1 and fig. 5, in the process of switching the electronic device 100 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 respectively apply magnetic attraction to the left end portion and the right end portion of the supporting mechanism 123, so that the left end portion of the supporting mechanism 123 moves to the left and the right end portion of the supporting mechanism 123 moves to the right, thereby driving the supporting mechanism 123 to be tensioned and unfolded, and the flexible screen 122 is driven by the supporting mechanism 123 to be tensioned and unfolded, as shown in fig. 3 and 4.

That is, the forces applied to the flexible screen 122 by the first magnetic mechanism 130a and the second magnetic mechanism 130b can be converted by the relative rotation between 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 different sections of 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 sliding rod 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 sliding rod 131 relative to the housing 121, as shown in fig. 1 and 4. When driven end 131a of sliding bar 131 moves through turn section 116, driven end 131a begins to be pushed into housing 121, so that sliding bar 131 slides relative to housing 121. When the driven end 131a of the slide bar 131 moves to (or abuts) the cam segment 117, the first magnet 132 faces the third magnet 134, as shown in fig. 5 and 7.

In order to ensure that the first magnet 132 slides along the sliding bar 131 and faces the second magnet 133 again during the process of the electronic device 100 transforming from the second state to the first state, 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 bar 131 to reset. The above-described magnetic design does not affect the facing state of the first magnet 132 and the third magnet 134 due to the abutting relationship between the slider 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 rotating shaft 140, wherein the pivot portion 121c is located between the first driving portion 113a and the second driving portion 113b, and the rotating shaft 140 is inserted into the first driving portion 113a, the second driving portion 113b and the pivot portion 121 c. On the other hand, housing 121 also has openings 121d (two shown) in side 121b for allowing driven end 131a of slider 131 to move out of or into housing 121.

As shown in fig. 4 and 7, as exemplified by the first magnetic mechanism 130a, the number of the first magnets 132 may be multiple and arranged on the sliding bar 131 along the first sliding direction D1. The number of the second magnets 133 and the number of the third magnets 134 may be multiple, wherein the second magnets 133 and the third magnets 134 are arranged alternately 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 group 135, and each magnet group 135 is disposed corresponding to a first magnet 132. As shown in fig. 1 and 4, for each magnet group 135, the second magnet 133 is located between the driving portion 113a and the third magnet 134 in the first sliding direction D1.

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 set 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 housing 121. Each movable rod 123b is configured to slide along the second sliding direction D2 relative to the housing 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 retracts and bends, and the second distance L2 is maintained between the two movable rods 123 b. During the process of the electronic device 100 transforming from the first state to the second state, the two movable rods 123b slide close to each other. On the other hand, during the process of the electronic device 100 transforming 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 middle support blocks 123c are juxtaposed between the two side support blocks 123a, wherein the middle support blocks 123c are connected to each other, and at least two of the middle support blocks 123c are respectively connected to the two side support blocks 123 a. Two adjacent middle support blocks 123c have freedom of movement in relative rotation, and one adjacent side support block 123a and one middle support block 123c have freedom of movement in relative rotation. When the electronic device 100 is switched 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 retracts and bends. On the other hand, when the electronic device 100 is switched 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 unfolded.

In this embodiment, the support mechanism 123 further includes a plurality of connection blocks 123d juxtaposed between the two side support blocks 123a, adjacent two middle support blocks 123c are connected to each other by one connection block 123d, and adjacent one side support block 123a and one middle support block 123c are connected to each other by one connection block 123 d. A middle support block 123c and a connecting block 123d connected have freedom of movement in relative rotation, while a side support block 123a and a connecting block 123d connected have freedom of movement in relative rotation.

For example, the number of the side support blocks 123a may be four, and any two side support blocks 123a are arranged and grouped along the first sliding direction D1, and a movable rod 123b penetrates through the two side support blocks 123a arranged in groups. A plurality of middle support blocks 123c are arranged between one side support block 123a and the other side support block 123a opposite to each other in the second sliding direction D2 in a row (row). Adjacent one of the side support blocks 123a and one of the middle support blocks 123c are connected to each other by a connection block 123d, and adjacent two of the middle support blocks 123c are connected to each other by a connection block 123 d. In the second sliding direction D2, the plurality of link blocks 123D are arranged in a row (row). In the first sliding direction D1, the plurality of connecting blocks 123D are sandwiched between one side support block 123a, the plurality of middle support blocks 123c, and the other side support block 123a of one row (row) and one side support block 123a, the plurality of middle 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 unfold the flexible screen, or generate a magnetic repulsion force to the flexible screen by the magnetic mechanism to bend the flexible screen. Because the curvature of the flexible screen is not fixed, the housing of the second body is not required to be designed into an arc structure in accordance with the curvature of the flexible screen, so as to meet the design requirement of thinning the product. When the second body is closed to the first body, the second body can be tightly attached to the first body, so that the problems of over-thickness of the whole electronic device, insufficient structural strength and the like can be avoided. 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 of the invention is very convenient for the user to operate. On the other hand, the flexible screen after bending can provide the user with a surrounding visual field, so that the user can have a visual immersion feeling.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
