Description

Technical Field

[0001] The utility model relates to a notebook computer. Background Art

[0002] Notebook computers are widely used due to their portability. Although various key components of notebook computers (such as SoC, power supply, memory, battery, etc.) are constantly upgraded with the development of technology, the appearance of notebook computers has not changed much. For example, notebook computers include three traditional appearances: clamshell, convertible, and detachable. At the same time, in order to meet the portability needs of users, manufacturers have been trying to reduce the height of notebook computers in the Z direction and reduce the weight of notebook computers. However, the length in the X direction and the width in the Y direction of notebook computers have rarely been concerned. Summary of the Utility Model

[0027] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present utility model.

[0028] Technologies and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies and devices should be regarded as part of the description.

[0029] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0030] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0031] Figure 1 A laptop computer 10 according to an embodiment of the present invention is shown in a three-dimensional view. Generally speaking, the laptop computer 10 includes: a base 12 which can be placed flat on a support surface such as a desktop; and a top cover 14. Here, the laptop computer 10, especially the top cover 14, is marked with an orthogonal coordinate system for the sake of explanation. The X direction is the length direction of the top cover 14, the Y direction is the width direction of the top cover 14, and the Z direction is the thickness direction of the top cover 14. That is to say, the main surface of the top cover 14 lies in the XY plane. The top cover 14 is connected to the base 12 in a rotatable manner about a main axis L1 extending in the X direction, so that the top cover 14 can be rotated relative to the base 12 to an open state (as Figure 1 , Figure 8 and Figure 10 shown) or a closed state (as Figure 6 , Figure 7 and Figure 9 shown). Hereinafter, unless otherwise specified, the description is made with reference to the open state of the top cover 14 Figures 1 to 4 . It can be understood that in the open state of the top cover 14, the length direction of the top cover 14 is consistent with the length direction of the base 12, and the width / thickness direction of the top cover 14 is angled with, for example, perpendicular to the width / thickness direction of the base 12. And in the closed state of the top cover 14, the length / width / thickness direction of the top cover 14 is all consistent with the length / width / thickness direction of the base 12.

[0032] For example, the top cover 14 includes a top cover housing 16. The top cover housing 16 includes a first top cover edge 17 extending in the X direction and is hinged to the base 12 at the first top cover edge 17 by means of a main hinge 18 defining the main axis L1.

[0033] Figure 2 The top cover 14 of the laptop computer 10 is shown in a side view, wherein the top cover housing 16 is at least partially removed for the sake of display. As Figure 2As shown, the upper cover 14 further includes: a flexible display screen 20, a first side edge 20a of the flexible display screen 20 extending in the X direction is fixed to the first upper cover edge 17, and a first region 22 of the flexible display screen 20 on the same plane as the first side edge 20a is visible to the user; a mounting member 24, the mounting member 24 is not visible to the user. Therefore, at least a part of the flexible display screen 20 is bent relative to the first side edge 20a (and thus is called a bending region 26) so that a second side edge 20b of the flexible display screen 20 opposite to and spaced apart from the first side edge 20a can be fixed to the mounting member 24, and the second side edge 20b is arranged parallel to the first side edge 20a, while a second region 30 of the flexible display screen 20 on the same plane as the second side edge 20b is not visible to the user.

[0034] Continuing as Figure 2 shown, the upper cover 14 further includes: a driving assembly 32 configured to drive the mounting member 24 to perform a linear motion along an upper cover axis L2 perpendicular to the main axis L1 and extending in the Y direction, so that the flexible display screen 20 is in an unfolded state (as Figure 2 shown) or a retracted state (as Figure 5 shown). The area of the first region 22 of the flexible display screen 20 in the unfolded state is larger than the area of the first region 22 in the retracted state. In other words, the area of the second region 30 of the flexible display screen 20 in the unfolded state is smaller than the area of the second region 30 in the retracted state. Thus, it can be seen that the flexible display screen 20 has a larger area on the same plane as the first side edge 20a in the unfolded state than in the retracted state. In other words, the flexible display screen 20 has a smaller area on the same plane as the second side edge 20b in the unfolded state than in the retracted state. The sum of the areas of the first region 22, the bending region 26, and the second region 30 of the flexible display screen 20 is the total area of the flexible display screen 20.

[0035] Returning to Figure 1 , the upper cover housing 16 includes: a first upper cover housing part 16a, the first upper cover edge 17 is integrally formed on the first upper cover housing part 16a, and the first upper cover housing part 16a further has a first matching member 34 extending in the Y direction perpendicular to the first upper cover edge 17; and a second upper cover housing part 16b, which has a second upper cover edge 36 opposite to and spaced apart from the first upper cover edge 17, and further has a second matching member 38 extending in the Y direction perpendicular to the second upper cover edge 36. The second matching member 38 is slidably disposed in the first matching member 34. For example, the second matching member 38 may be in the form of a flat smooth rod, and the first matching member 34 may be in the form of a groove complementary to the shape of the flat smooth rod. Here, the form of the first matching member 34 and the specific form of the second matching member 38 are not limited.

[0036] Referring to Figure 3and Figure 4 , wherein Figure 3 shows three driving components 32, but the number of driving components 32 may vary according to circumstances Figure 4 shows an exploded view of one of the driving components 32 and the mounting member 24, wherein a part of the first upper cover housing part 16a is cut off. The first upper cover housing part 16a defines an accommodation space 40, and the driving component 32 is substantially laid flat in the accommodation space 40 on the XY plane to prevent excessive increase in the Z-direction height of the upper cover 14. Specifically, the driving component 32 includes: a motor 42 and a support box 44 disposed in the first upper cover housing part 16a, the support box 44 defines a rotation space 46 and is open on the XY plane; and a transmission member 48 disposed in the support box 44 to be located in the rotation space 46. For example, the form of the transmission member 48 may be a ball screw, a trapezoidal screw, a roller guide, a screw, etc. The transmission member 48 defines the upper cover axis L2 itself. Especially as Figure 4 shown, the mounting member 24 includes a first mounting member part 24a located in the support box 44 and extended through by the transmission member 48 and a second mounting member part 24b located above the support box 44 on the XY plane. That is to say, the second mounting member part 24b is fixed to the first mounting member part 24a, and the Z-direction thickness of the first mounting member part 24a is substantially equal to the Z-direction thickness of the support box 44. In this way, the second side 20b of the flexible display screen 20 can be stably fixed to the second mounting member part 24b and the unfolding and folding processes of the flexible display screen 20 will not be interfered or blocked by the support box 44. The transmission member 48 further extends through the support box 44 to be connected to the motor 42 located outside but adjacent to the support box 44. Thus, the transmission member 48 can be configured to be driven by the motor 42 to perform a rotational movement around the upper cover axis L2 in the rotation space 46, and the rotational movement further causes the mounting member 24 to perform a linear movement along the upper cover axis L2

[0037] Optionally, the driving component 32 further includes: at least one guide rod 50 disposed in the support box 44 parallel to the upper cover axis L2 (for example, two guide rods 50 respectively located on both sides of the transmission member 48), the at least one guide rod 50 extends through the first mounting member part 24a to guide the mounting member 24 to perform a linear movement along the upper cover axis L2, thereby further preventing the mounting member 24 from flipping

[0038] Optionally, in order to facilitate the second mounting member part 24b to drive the flexible display screen 20, especially the second side 20b, the second mounting member part 24b is formed to have a protruding section 43 that slightly protrudes above the support box 44 along the upper cover axis L2 in the unfolded state of the flexible display screen 20

[0039] It can be seen that an end face of the second mounting part 24b on the protruding section 43 is close to the bending area 26 of the flexible display screen 20. Therefore, as shown not to scale Figure 5 As shown, a rounding structure 46 can be provided on the end face to prevent the protruding section 43 of the second mounting part 24b from damaging the flexible display screen 20 when it may come into contact with the bending area 26 of the flexible display screen 20.

[0040] Supplementary or alternatively, a Y-direction end 44a of the support box 44 is also close to the bending area 26 of the flexible display screen 20. Another rounding structure 47 can be provided on the end face of the Y-direction end 44a to prevent the support box 44 from damaging the flexible display screen 20 when it may come into contact with the bending area 26 of the flexible display screen 20.

[0041] The rounding structures 46 and 47 can be made of an elastic material (for example, a plastic material). Alternatively, the end face of the protruding section 43 of the second mounting part 24b and / or the end face of the Y-direction end 44a of the support box 44 itself has a rounded shape, and an elastic layer can cover the end face of the protruding section 43 of the second mounting part 24b and / or the end face of the Y-direction end 44a of the support box 44.

[0042] It can be understood that the mounting part 24 can be further connected to the second upper cover housing part 16b so that when the flexible display screen 20 is switched between the unfolded state and the folded state, the second upper cover housing part 16b can slide relative to the first upper cover housing part 16a along the upper cover axis L2. In the unfolded state of the flexible display screen 20, the second upper cover edge 36 is farthest from the first upper cover edge 17 (as Figure 1 shown), and in the folded state of the flexible display screen 20, the second upper cover edge 36 is closest to the first upper cover edge 17. Alternatively, the mounting part 24 may not be connected to the second upper cover housing part 16b, but the second upper cover housing part 16b can be manually slid relative to the first upper cover housing part 16a along the upper cover axis L2 after the flexible display screen 20 is switched from the unfolded state to the folded state, or before the flexible display screen 20 is switched from the folded state to the unfolded state. Alternatively, an additional driving component can also be used to drive the second upper cover housing part 16b to slide relative to the first upper cover housing part 16a along the upper cover axis L2.

[0043] In the above configuration, as Figure 2 shown, the mounting part 24 can perform a linear motion along the upper cover axis L2 away from the first upper cover edge 17. When the first mounting part 24a moves to abut against the Y-direction end 44a of the support box 44, the flexible display screen 20 is in a fully unfolded state, and as Figure 5As shown, the mounting member 24 performs a linear motion along the upper cover axis L2 to approach the first upper cover edge 17. When the first mounting member portion 24a moves to abut against the other Y-direction end 44b of the support box 44 opposite to the one Y-direction end 44a, the flexible display screen 20 is in a retracted state. Among them, the area of the flexible display screen 20 in the unfolded state on the same plane as the first side 20a is 1.2 to 2 times, such as 1.4 times, 1.6 times, 1.8 times, etc., of the area of the flexible display screen 20 in the retracted state on the same plane as the first side 20a.

[0044] Here, the present utility model also provides a series of configurations regarding the base 12.

[0045] Return to Figure 1 , the base 12 includes a keyboard area 52 and a touch area 54. The first end side 52a of the keyboard area 52 is close to the main hinge 18. The second end side 52b of the keyboard area 52 opposite to the first end side 52a is hinged to the touch area 54 by means of a first additional hinge 53 (as Figure 6 shown) that defines a first base axis L3 parallel to the main axis L1, so that the touch area 54 can rotate relative to the keyboard area 52 around the first base axis L3 to directly cover the keyboard area 52 or the upper cover 14. The keyboard area 52 also has a first main surface 52c extending between the first end side 52a and the second end side 52b and a second main surface opposite to the first main surface 52c. There is a keyboard 56 on the first main surface 52c, and the second main surface can be placed flat on a support surface such as a desktop. For example, as Figure 6 shown, when it is desired to carry the laptop 10, the upper cover 14 can be rotated relative to the base 12 around the main axis L1 to be closed, so that the flexible display screen 20 in the retracted state of the upper cover 14 covers / overlaps the first main surface 52c of the keyboard area 52, and the touch area 54 can be rotated relative to the keyboard area 52 around the first base axis L3 to cover / overlap the second main surface of the keyboard area 52. Alternatively, as Figure 7As shown, the second end side 52b of the keyboard area 52 opposite to the first end side 52a is hinged to the touch area 54 by means of a second additional hinge 55 that defines a second base axis L4 parallel to the main axis L1. When it is desired to carry the laptop 10, first, the upper cover 14 can be rotated relative to the base 12 about the main axis L1 to the closed position so that the flexible display screen 20 in the stowed state of the upper cover 14 covers / overlaps the first main surface 52c of the keyboard area 52. Then, the touch area 54 can be rotated relative to the keyboard area 52 about the second base axis L4 to cover / overlap the back surface of the upper cover 14 opposite to the main surface where the flexible display screen 20 is located. In this case, the second additional hinge 55 can be configured as a diaphragm hinge with an appropriate width. Optionally, in the stowed state of the flexible display screen 20, the width of the upper cover 14 along the upper cover axis L2 is substantially equal to the corresponding width of the keyboard area 52. Additionally, the touch area 54 can be different from the keyboard area 52 in terms of the dimension in the Y direction.

[0046] Alternatively, as Figure 8 shown, the base 12 may not be provided with a keyboard area and a touch area, but instead with an additional flexible display screen 21. It can be understood that the components related to the functions of the keyboard area and the touch area can be provided in the form of detachable accessories. Thus, the base 12 includes: a base housing 58, and the base housing 58 includes: a first base portion 60 having a first main surface 60a and a second main surface opposite to the first main surface 60a, and a part of the additional flexible display screen 21 is disposed relative to the first main surface 60a of the first base portion 60; and a second base portion 62 which also has a first main surface 62a and a second main surface opposite to the first main surface 62a, and the remaining part / another part of the display screen is disposed relative to the first main surface 62a of the second base portion 62. The second main surface of the first base portion 60 and the second main surface of the second base portion 62 can be laid flat on a support surface such as a desktop. The main hinge 18 is provided at the first end side 62c of the first main surface 62a of the second base portion 62, and the second end side 62d of the second base portion 62 opposite to the first end side 62c can be hinged to the first base portion 60 by means of a third additional hinge 66 that defines a third base axis L5 parallel to the main axis L1 so that the first base portion 60 and a part of the additional flexible display screen 21 can be rotated relative to the second base portion 62 about the third base axis L5 to directly cover / overlap the upper cover 14. Thus, as Figure 9As shown, when it is desired to carry the laptop 10, first, the upper cover 14 can be rotated relative to the base 12 about the main axis L1 to a closed position so that the flexible display screen 20 of the upper cover 14 covers / overlaps the first main surface 62a of the second base portion 62. Then, the first base portion 60 and a part of the additional flexible display screen 21 can be rotated relative to the second base portion 62 about the third base axis L5 to cover / overlap the back surface of the upper cover 14. Optionally, in the retracted state of the flexible display screen 20, the width of the upper cover 14 along the upper cover axis L2 is substantially equal to the corresponding width of the second base portion 62.

[0047] Alternatively, as Figure 10 shown, the base 12 can have the same configuration as the upper cover 14. That is, the base 12 includes: a telescopic base housing 59, which includes a base edge 59a provided with a main hinge 18; an additional flexible display screen 21, with the first additional side edge of the additional flexible display screen 21 fixed to the base edge 59a; an additional mounting member, at least a part of the additional flexible display screen 21 being bent so that the second additional side edge of the additional flexible display screen 21 opposite to the first additional side edge is fixed to the additional mounting member and arranged parallel to the first additional side edge; and an additional drive assembly configured to drive the additional mounting member to perform a linear motion along a fourth base axis L6 perpendicular to the main axis L1 so that the additional flexible display screen 21 is in an unfolded state or a retracted state, and the additional flexible display screen 21 has a larger area in the same plane as the first additional side edge in the unfolded state than in the retracted state. Optionally, in the retracted state of the flexible display screen 20, the width of the upper cover 14 along the upper cover axis L2 is substantially equal to the corresponding width of the base 12 in the retracted state of the additional flexible display screen 21 along the fourth base axis L6. Generally speaking, the configuration of the base 12 can fully refer to the description of the upper cover 14 in Figures 1 to 5 this regard.

[0048] As an alternative embodiment where the upper cover 14 has a variable width in the Y direction, an alternative upper cover can be provided. For example, the relevant components for the unfolded state and the retracted state of the flexible display screen of the alternative upper cover are rotated 90 degrees so that the alternative upper cover can achieve a variable length in the X direction. That is, the upper cover axis will become parallel to the main axis. Correspondingly, in an alternative embodiment where an additional flexible display screen is provided on the alternative base, the alternative base can be rotated about a third base axis L5 perpendicular to the main axis L1, or the configuration of the alternative base can fully refer to the configuration of the alternative upper cover. It should be understood that the number and specific structure of the main hinge and other relevant components may change here.

[0049] Although some specific embodiments of the present utility model have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration purposes and not for limiting the scope of the present utility model. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present utility model. The scope of the present utility model is defined by the appended claims.
