Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application.
In describing embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. refer to an azimuth or a positional relationship based on that shown in the drawings, or that the inventive product is conventionally put in place when used, merely for convenience of describing the present application and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
Furthermore, the terms "horizontal," "vertical," and the like do not denote a requirement that the component be absolutely horizontal or overhang, but rather may be slightly inclined. As "horizontal" merely means that its direction is more horizontal than "vertical", and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
In the description of the embodiments of the present application, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," "coupled" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
In the entire specification, when an element (such as a layer, region or substrate) is described as being "on", "connected to", "bonded to", "over" or "covering" another element, it may be directly "on", "connected to", "bonded to", "over" or "covering" another element or there may be one or more other elements interposed therebetween. In contrast, when an element is referred to as being "directly on," directly connected to, "or" directly coupled to, "another element, directly on," or "directly covering" the other element, there may be no other element intervening therebetween.
As used herein, the term "and/or" includes any one of the listed items of interest and any combination of any two or more.
For ease of description, spatially relative terms such as "above … …," "upper," "below … …," and "lower" may be used herein to describe one element's relationship to another element as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "upper" relative to another element would then be oriented "below" or "lower" relative to the other element. Thus, the term "above … …" includes both orientations "above … …" and "below … …" depending on the spatial orientation of the device. The device may also be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. Singular forms also are intended to include plural forms unless the context clearly indicates otherwise. The terms "comprises," "comprising," and "having" are intended to specify the presence of stated features, integers, operations, elements, and/or groups thereof, but do not preclude the presence or addition of one or more other features, integers, operations, elements, and/or groups thereof.
Variations from the shapes of the illustrations as a result, of manufacturing techniques and/or tolerances, are to be expected. Accordingly, the examples described herein are not limited to the particular shapes shown in the drawings, but include changes in shapes that occur during manufacture.
The features of the examples described herein may be combined in various ways that will be apparent upon an understanding of the present disclosure. Further, while the examples described herein have a variety of configurations, other configurations are possible as will be apparent after an understanding of the present disclosure.

According to a first embodiment of the present invention, there is provided a hinge assembly, as shown in fig. 1 to 4, the hinge assembly according to the present embodiment may include: the device comprises a first transmission shaft, a second transmission shaft, an idler fixing seat, a plate-shaped cladding component, an adjusting member, a supporting piece, a plurality of torsion adjusting pieces, a first torsion reed group, a second torsion reed group and two fastening nuts.
Hereinafter, the structure and actions of the above-described components of the hinge assembly according to the present embodiment will be specifically described.
As shown in fig. 1 to 4, in an embodiment of the present invention, the idler fixing seat 10 may include first and second mounting holes disposed to be spaced apart from each other and an idler receiving portion interposed between the first and second mounting holes. In the embodiment, the idler gear 13 is fitted into the idler gear accommodating portion of the idler gear fixing base 10, and the first and second drive shafts 11 and 12 are disposed side by side parallel to each other and penetrate into the first and second mounting holes of the idler gear fixing base 10, respectively, so that the first and second drive shafts 11 and 12 are engaged with the idler gear 13 mounted in the idler gear accommodating portion, respectively, causing the first and second drive shafts 11 and 12 to rotate in linkage in mutually opposite rotational directions. Furthermore, in the embodiment of the present invention, the idler fixing base 10 can support the first transmission shaft 11, the second transmission shaft 12, and the idler 13.
As shown in fig. 1 to 4, a plurality of torsion tabs 20 may be provided through the first and second driving shafts 11 and 12 in a stacked manner with each other. In the embodiment shown in fig. 1 and 2, the torsion tab 20 may be formed as a torsion tab having two clip axle holes. In fig. 1 and 2, both of the grip shaft holes of each torsion tab 20 are formed to be open, but not limited thereto, but only one of the two grip shaft holes may be formed to be open, so that stress generated between the rotating drive shaft and the grip shaft hole can be relieved, and such torsion tab can elastically press the two drive shafts in the radial direction. The specific form of the torsion adjusting piece that provides the torsion is not limited as long as the torsion adjusting piece can achieve adjustment of the torsion of the first transmission shaft 11 and the second transmission shaft 12.
Next, as shown in fig. 1 to 4, the first torsion reed group 21 and the second torsion reed group 22 may be respectively provided to the first transmission shaft 11 and the second transmission shaft 12 for changing the torsion to be applied to the first transmission shaft 11 and the second transmission shaft 12. For example, the first torsion spring group 21 and the second torsion spring group 22 are identical in structure. Specifically, each of the first torsion spring group 21 and the second torsion spring group 22 may include, for example, a plurality of disc springs, that is, a plurality of disc springs of the first torsion spring group 21 are assembled to be closely stacked to each other, and a plurality of disc springs of the second torsion spring group 22 are assembled to be closely stacked to each other, thereby providing a rotation torsion to the first transmission shaft 11 and the second transmission shaft 12.
Next, as shown in fig. 1 to 4, two fastening nuts 23 may be screwed on the ends of the first and second transmission shafts 11 and 12, respectively, to press the plurality of torsion tabs 20 and the first and second torsion reed groups 21 and 22. As an example, the fastening nut 23 may be screwed into a designated or desired torque level by a wrench or the like, thereby applying a force to the first torsion spring set 21, the second torsion spring set 22, and the plurality of torsion tabs 20, respectively. In addition, washers may be added to the fastening nuts 23 and the corresponding torsion reed groups. Further, as shown in fig. 1 to 4, the support 30 is provided between the plate-like sheathing member 40 and the torsion reed group as described below.
Further, alternatively, the hinge assembly may include any one or combination of a plurality of torsion tabs, a plate-like wrapping torsion member, and a torsion spring set and a fastening nut. Specifically, the hinge assembly may include any one or combination of a plurality of torsion tabs, a plate-like wrapping torsion member, and a torsion spring set and a fastening nut, depending on the actual design requirements.
Further, hereinafter, the plate-shaped sheathing part and the adjustment member of the hinge assembly according to an embodiment of the present invention will be described in detail.
In an embodiment of the present application, the plate-shaped sheathing member 40 may be formed with first and second sheathing holes 41 and 42 spaced apart from each other. The first and second propeller shafts 11 and 12 as described above may penetrate into the first and second sheathing holes 41 and 42, respectively, and are elastically sheathed and pressed by the first and second sheathing holes 41 and 42, respectively.
Further, the plate-like sheathing member 40 may further include an overlapped portion interposed between the first sheathing hole 41 and the second sheathing hole 42, which includes a first inner wall portion 43 and a second inner wall portion 44 facing each other. Further, a void portion 45 is formed in the first and second inner wall portions 43 and 44, the void portion 45 being in communication with the first and second coating holes 41 and 42, respectively, such that the plate-like coating member 40 enables the first and second coating holes 41 and 42 to elastically coat and tighten the first and second drive shafts 11 and 12.
In an embodiment, the second inner wall portion 44 may be provided with a through hole portion 47, and the first inner wall portion 43 may be provided with a hole portion 46. That is, the hole portion of the first inner wall portion 43 may be a through hole or a non-through hole according to design requirements.
In the embodiment, the regulating member 50 is sequentially inserted into the through hole portion 47 of the second inner wall portion 44 and the hole portion 46 of the first inner wall portion 43, thereby regulating the degree of elastic deformation of the first inner wall portion 43 and the second inner wall portion 44, and thus regulating the magnitude of the coating force applied to the first transmission shaft 11 and the second transmission shaft 12 by the first coating hole 41 and the second coating hole 42, respectively. Specifically, if it is desired to cause the first and second sheathing holes 41 and 42 to give a relatively tight sheathing to the first and second transmission shafts 11 and 12, the regulating member 50 may be inserted deeper into the hole portion 46 of the first inner wall portion 43. Conversely, if it is desired to have the first and second sheathing holes 41 and 42 produce a relatively loose sheathing of the first and second transmission shafts 11 and 12, the adjustment member 50 may be inserted shallower into the hole portion 46 of the first inner wall portion 43.
Hereinafter, embodiments of the regulating member will be described in detail.
For example, as shown in fig. 1 to 4, the regulating member 50 may be a screw, in which case the through hole portion 47 of the second inner wall portion 44 is formed with an internal thread for engagement with the screw; the hole 46 of the first inner wall 43 may be a through hole or a blind hole formed with a female screw, so that a screw can be sequentially inserted into the through hole or the blind hole of the second inner wall 44 and the through hole or the blind hole of the first inner wall 43 formed with a female screw (in the embodiment of the figure, the hole 46 of the first inner wall 43 is a through hole).
However, not limited thereto, although not shown, the adjustment member may include, for example, a bolt and a nut, in which case the hole portion of the first inner wall portion should be a through hole portion, but the through hole portion of the second inner wall portion may be formed with or without an internal thread without being provided with an internal thread.
Further, as shown in fig. 3 to 6, in the embodiment, the cross-sectional shape of the plate-like sheathing member 40 is a dumbbell shape, which may be a shape that is integrally closed or one of the first inner wall portion 43 and the second inner wall portion 44 is opened, when viewed along the axis of the first propeller shaft 11 or the axis of the second propeller shaft 12.
In the embodiment shown in fig. 3 to 6, the second inner wall portion 44 is formed with a broken portion 443, and the second inner wall portion 44 includes a first transmission shaft side portion 441 and a second transmission shaft side portion 442. In the embodiment, the first transmission shaft side portion 441 and the second transmission shaft side portion 442 are separated from each other at the center of the second inner wall portion 44 to form the cutoff portion 443. The through hole portion 47 of the second inner wall portion 44 includes first and second through hole portions that are respectively opened at the first and second transmission shaft side portions 441 and 442 of the second inner wall portion 44; the hole 46 of the first inner wall 43 includes a first hole and a second hole, which are respectively provided at positions of the first inner wall 43 corresponding to the first through hole and the second through hole; the regulating member includes a first regulating member inserted into the first through hole portion and the first hole portion, and a second regulating member inserted into the second through hole portion and the second hole portion.
With the broken portions as described above, it is possible to more conveniently adjust the coating forces applied to the first and second transmission shafts 11 and 12 by the first and second coating holes 41 and 42, and to install the adjustment members 50 on the first and second transmission shaft side portions 441 and 442, respectively, thereby more stably adjusting the coating forces applied to the first and second transmission shafts 11 and 12 by the first and second coating holes 41 and 42.
Of course, the number and arrangement of the regulating members are not limited thereto. For example, even in the case where the second inner wall portion is not formed with the broken portion, two regulating members may be provided, and of course, three regulating members may be provided, or even more regulating members may be provided. For example, in the case where the second inner wall portion is formed with the break-away portion, two regulating members may be provided on the first transmission shaft side portion and the second transmission shaft side portion, respectively. That is, the number and arrangement of the regulating members are not particularly limited as long as the coating force applied by the first coating holes and the second coating holes can be stably regulated.
In addition, as shown in fig. 7, the hinge assembly may further include a housing 300, the housing 300 surrounding most of the components of the hinge assembly, i.e., the housing 300 is disposed at the outside of the hinge assembly body, thereby protecting the first transmission shaft, the second transmission shaft, the idle gear fixing seat, the plate-shaped sheathing member, the adjusting member, the supporter, the plurality of torsion tabs, the first torsion reed group, the second torsion reed group, the two fastening nuts, etc.

The hinge assembly according to the second embodiment of the present invention is different from the hinge assembly according to the first embodiment of the present invention only in the plate-shaped packing member 60 and the adjusting screw 70, and differences between the two embodiments will be mainly described below with respect to the plate-shaped packing member and the adjusting screw. While the first transmission shaft, the second transmission shaft, the idler pulley holder, the plurality of torsion tabs, the first torsion spring group, the second torsion spring group, and the two fastening nuts of the hinge assembly according to the second embodiment of the present invention are the same as those of the hinge assembly according to the first embodiment, overlapping descriptions will be omitted herein. Further, the illustration of the above-described assembly is omitted for simplicity of illustration, and only the plate-like sheathing member and the adjusting screw according to the second embodiment of the present invention are shown in fig. 8 and 9.
The plate-shaped sheathing member of the hinge assembly according to the second embodiment is similarly formed with first and second sheathing holes 61 and 62 spaced apart from each other. The first and second transmission shafts penetrate into the first and second coating holes 61 and 62, respectively, and are elastically coated and urged by the first and second coating holes 61 and 62, respectively.
In an embodiment, the plate-like cladding member further comprises an overlap between the first cladding hole 61 and the second cladding hole 62. The overlapping portion includes a first inner wall portion 63 and a second inner wall portion 64 facing each other, a void portion 65 is formed in the first inner wall portion 63 and the second inner wall portion 64, and the void portion 65 communicates with the first coating hole 61 and the second coating hole 62, respectively, such that the plate-like coating member enables the first coating hole 61 and the second coating hole 62 to elastically coat and press the first transmission shaft and the second transmission shaft.
In the embodiment, the second inner wall portion 64 is provided with a screw hole portion 66, while the first inner wall portion 63 is not provided with a hole portion; in this case, the adjusting screw 70 is inserted into the screw hole portion 66 of the second inner wall portion 64 so that the end portion of the adjusting screw can abut against the first inner wall portion 63, thereby adjusting the degree of elastic deformation of the first inner wall portion 63 and the second inner wall portion 64, and thus adjusting the magnitude of the coating force applied to the first transmission shaft and the second transmission shaft by the first coating hole 61 and the second coating hole 62, respectively.
Specifically, if it is desired to have the first and second coating holes 61 and 62 produce a relatively tight coating of the first and second drive shafts, the adjustment screw 70 may be weakly abutted against the first inner wall portion 63, i.e., weakly jacked up the first inner wall portion 63. Conversely, if it is desired to have the first and second coating holes 61 and 62 produce a relatively loose coating of the first and second drive shafts, the adjustment screw 70 may be strongly abutted against the first inner wall portion 63, i.e., strongly jacked up the first inner wall portion 63.
The number and arrangement of the adjustment screws are not limited thereto, similarly to the adjustment member of the first embodiment. For example, even in the case where the second inner wall portion is not formed with the broken portion, two adjusting screws may be provided, and of course, three adjusting screws may be provided, or even more adjusting screws may be provided. For example, in the case where the second inner wall portion is formed with the break portion, two adjusting screws may be provided on the first transmission shaft side portion and the second transmission shaft side portion, respectively. That is, the number and arrangement of the adjustment screws are not particularly limited as long as the coating forces applied by the first and second coating holes can be stably adjusted.
Further, according to another aspect of the present invention, there is provided a notebook computer including the hinge assembly, the screen, and the keyboard as described above. In an embodiment, as shown in fig. 1 to 4, the screen may be fixedly connected to the first transmission shaft 11 via the first connection plate 100, and the keypad may be fixedly connected to the second transmission shaft 12 via the second connection plate 200, so that the screen and the keypad can be rotated in linkage in opposite rotational directions to each other.
Finally, it should be noted that: the above examples are only specific embodiments of the present application, and are not intended to limit the scope of the present application, but it should be understood by those skilled in the art that the present application is not limited thereto, and that the present application is described in detail with reference to the foregoing examples: any person skilled in the art may modify or easily conceive of the technical solution described in the foregoing embodiments, or perform equivalent substitution of some of the technical features, while remaining within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and are intended to be included in the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
