In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0061] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0062] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0063] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0064] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first member, component, region, layer, or portion referred to may also be referred to as the second member, component, region, layer, or portion.

[0065] For ease of description, spatial relational terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings. Such spatial relational terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings.

In addition, the first shell member 41 is penetrated by both the first rotating shaft 10 and the second rotating shaft 20, and similarly, the second shell member 42 is also penetrated by both the first rotating shaft 10 and the second rotating shaft 20, as shown in FIG. Figures 1 to 6 As shown, the first shell member 41 and the second shell member 42 are located on both sides of the third rotating shaft 30 in the axial direction of the first rotating shaft 10; the first shell member 41 is formed with a first end 411, which faces the second shell member 42, and the second shell member 42 is formed with a second end 421, which faces the first shell member 41. In addition, in the embodiment, the third rotating shaft 30 is a hollow shaft.

[0074] Hereinafter, the action process of the hinge assembly will be described in combination with the first posture and the second posture of the hinge assembly.

In an embodiment, the predetermined angle described here is 90 degrees.

[0076] In the second posture of the hinge assembly, when viewed along the rotation axis direction of the first rotation axis 10 or the axis direction of the second rotation axis 20 , the limiting portion 301 of the third rotation axis 30 does not overlap with the first end 411 of the first shell member 41 and the second end 421 of the second shell member 42 .

[0077] During the transition from the first posture to the second posture, the limiting portion 301 is between the first end portion 411 of the first shell member 41 and the second end portion 421 of the second shell member 42, and contacts the first end portion 411 of the first shell member 41 and the second end portion 421 of the second shell member 42 respectively. When viewed along the rotation axis direction of the first rotation axis 10 or the axis direction of the second rotation axis 20, the limiting portion 301 of the third rotation axis 30 at least partially overlaps with the first end portion 411 of the first shell member 41 and the second end portion 421 of the second shell member 42, so that the third rotation axis 30 can be restricted from rotating during the transition from the first posture to the second posture of the hinge assembly. That is, within the range of 90 degrees of relative rotation of the first rotation axis 10 and the second rotation axis 20, the third rotation axis 30 cannot rotate.

[0078] In an embodiment, the first rotating shaft 10 may include a first shaft section 101 and a second shaft section 102 spaced apart from each other, the first shaft section 101 may be formed with a first arc-shaped portion 1011 and a first notch 1012, and the second shaft section 102 may be formed with a second arc-shaped portion and a second notch.

[0080] In addition, the first intermediate component 51 can be located between the first shaft section 101 and the third shaft section 201 and have a first side surface and a second side surface facing away from each other, and the first shell component 41 covers the first intermediate component 51, thereby protecting the first intermediate component 51, the first shaft section 101 and the third shaft section 201, and providing a first end 411 for interacting with the limiting portion 301 of the third rotating shaft 30; the second intermediate component can be located between the second shaft section 102 and the fourth shaft section and have a first side surface and a second side surface facing away from each other, and the second shell component 42 covers the second intermediate component, thereby protecting the second intermediate component, the second shaft section 102 and the fourth shaft section, and providing a second end 421 for interacting with the limiting portion 301 of the third rotating shaft 30.

[0081] In addition, at least one of the first shaft section 101 and the second shaft section 102 of the first rotating shaft 10 is formed with a protrusion 81 protruding from the outer periphery of at least one of them, and at least one of the first shell member 41 and the second shell member 42 is formed with a stopper 43 corresponding to the protrusion 81 at the end thereof.

However, it is not limited to this, and it can also be that only one of the first shaft section 101 and the second shaft section 102 of the first rotating shaft 10 is formed with the protrusion 81 protruding from the periphery of the one, and only the end of the first shell member 41 and the second shell member 42 is formed with the limiting protrusion 43 corresponding to the protrusion 81.

[0082] In addition, in the embodiment, the first movable member 61 can be slidably installed on the first end 411 of the first shell member 41; the second movable member 62 can be slidably installed on the second end 421 of the second shell member 42; the first elastic member (not shown) is arranged at the first end 411 of the first shell member 41 and applies force to the first movable member 61 toward the third shaft section 201; the second elastic member (not shown) is arranged at the second end 421 of the second shell member 42 and applies force to the second movable member 62 toward the fourth shaft section; the third shaft section 201 presses against the second end of the first movable member 61, and the fourth shaft section presses against the second end of the second movable member 62.

[0083] In the embodiment, preferably, the first moving member 61 and the second moving member 62 may be formed as moving blocks.

[0084] In the embodiment, preferably, the first elastic member and the second elastic member can be formed as springs, however, not limited thereto, as long as the first elastic member and the second elastic member can continuously apply force to the first movable member 61 and the second movable member 62, the first elastic member and the second elastic member can also adopt other forms.

[0085] In the embodiment, although not shown in the figure, the first elastic member and the second elastic member can be assembled to the first end 411 of the first shell member 41 and the second end 421 of the second shell member 42 in the following manner. Specifically, since the first elastic member and the second elastic member are arranged in the same manner, only the first elastic member is described as an example. The first elastic member is arranged at a position where the first movable member 61 cooperates with the first end 411 of the first shell member 41. Preferably, a receiving groove can be formed in a predetermined portion of the first end 411 of the first shell member 41, and the first elastic member is arranged in the receiving groove, and the first movable member is formed with a protrusion extending into the receiving groove, such as a first elastic member of a spring that can continuously apply an elastic force to the protrusion of the first movable member.

[0091] In the process of converting from the second posture of the hinge assembly to the third posture as described above, the first rotating shaft 10 is stationary, the second rotating shaft 20 rotates by a second predetermined angle, the third shaft section 201 pushes against the first moving member 61, so that the first moving member 61 moves toward the first shaft section 101, and the fourth shaft section pushes against the second moving member 62, so that the second moving member 62 moves toward the second shaft section 102. The second predetermined angle described here is 90 degrees.

[0092] That is, when the hinge assembly changes from the first posture to the second posture, the first rotation axis 10 rotates 90 degrees and the second rotation axis 20 remains stationary, and when the hinge assembly changes from the second posture to the third posture, the first rotation axis 10 remains stationary and the second rotation axis 20 rotates 90 degrees. In addition, this operation will be described below in conjunction with a laptop computer.

[0093] In addition, preferably, the first movable member 61 includes a first plate-shaped portion 611 abutting against the third shaft section 201 and a first strip-shaped portion 612 protruding from the first plate-shaped portion 611 toward the first shaft section 101, and the first end portion 411 of the first shell member 41 is formed with a first recess, and the first strip-shaped portion 612 is slidably embedded in the first recess.

[0094] In addition, further preferably, the first strip portion 612 can be formed into a step shape, and correspondingly, the first recessed portion of the first end portion 411 of the first shell member 41 can also be formed into a step shape, so that the first movable member 61 can be limited to the first recessed portion, thereby preventing the first movable member 61 from escaping from the first recessed portion.

[0095] In other words, the first end portion 411 of the first shell member 41 may be formed with a first portion and a second portion separated from each other, and the portions of the first portion and the second portion facing each other are both formed in a step shape, and the two side portions of the first strip portion 612 of the first movable member 61 are both formed in a step shape. With the structure described above, the two side portions of the first strip portion 612 of the first movable member 61 may respectively cooperate with the first portion and the second portion of the first end portion 411 of the first shell member 41. For example, the accommodating groove described above may be formed at a predetermined position of the first portion and / or the second portion of the first end portion 411 of the first shell member 41.

[0096] As described above, in the process of the hinge assembly from the first posture to the second posture and in the process of the hinge assembly from the second posture to the third posture, the first strip portion 612 of the first moving member 61 reciprocates in the first recess.

Since the structure and function of the second plate-shaped portion 621 and the second strip-shaped portion 622 of the second movable member 62 are the same as those of the first plate-shaped portion 611 and the first strip-shaped portion 612 of the first movable member 61, and the second recess 4211 of the second end portion 421 of the second shell member 42 is the same as the first recess of the first end portion 411 of the first shell member 41, the description of the second movable member 62 and the second recess 4211 is omitted.

[0098] In addition, if Figures 1 to 6 As shown, the first sleeve 90 is rotatably mounted on the third rotating shaft 30 and abuts against the top of the through hole 103, a portion of the first sleeve 90 close to the through hole 103 is formed with a notch portion 901, and a first limiting protrusion 1031 located in the notch portion 901 is formed at the top of the through hole 103; in an embodiment, the first sleeve 90 abuts against the side of the through hole 103 opposite to the side where the limiting portion 301 is located.

[0099] The second sleeve 91 is rotatably mounted on the third rotating shaft 30, and a second limiting protrusion 902 extending toward the second sleeve 91 and abutting against the bottom of the second sleeve 91 is formed at the top of the first sleeve 90, and a third limiting protrusion 911 extending toward the first sleeve 90 and abutting against the top of the first sleeve 90 is formed at the bottom of the second sleeve 91; in an embodiment, the second sleeve 91 is arranged on the side of the first sleeve 90 opposite to the side where the through hole 103 is located.

[0100] As the third rotating shaft 30 rotates, the first sleeve 90 and the second sleeve 91 rotate synchronously, and the first limiting protrusion 1031 moves in the notch 901 until both ends of the notch 901 in the circumferential direction of the first sleeve 90 abut against the first limiting protrusion 1031, and the first sleeve 90 stops rotating. When the first sleeve 90 stops rotating, the second sleeve 91 stops rotating until the third limiting protrusion 911 of the second sleeve 91 abuts against the second limiting protrusion 902 of the first sleeve 90. In addition, the second sleeve 91 as described above is a part of the first connecting plate 1 as described above.

[0101] By utilizing the double sleeve structure as described above, the third rotation axis 30 can be swung in the second posture of the hinge assembly, thereby effectively controlling the angular range within which the third rotation axis 30 can swung.

[0102] In addition, if Figures 1 to 6 As shown, the first connecting plate 1 is connected to the third rotating shaft 30 , and the first connecting plate 1 is used to be connected to a screen, for example.

The operation of the screen and the keyboard will be described later. In addition, the front and back screens of the laptop computer using the hinge assembly according to this embodiment can be attached to the desktop.

[0104] Furthermore, by using the hollow shaft structure of the third rotation shaft 30 of the hinge assembly according to the present embodiment, wiring can be effectively and reasonably performed.

[0105] In addition, if Figures 1 to 6 As shown, a plurality of torque adjustment sheets 71 can be stacked on each other and pass through the first rotating shaft 10 and the second rotating shaft 20. Figure 1In the embodiment shown in , a plurality of torque adjustment sheets 71 are provided on both sides of the first rotating shaft 10 and the second rotating shaft 20. To simplify the description, only the single-side structure of the first rotating shaft 10 and the second rotating shaft 20 is used as an example for description. Preferably, each torque adjustment sheet 71 can be formed into an "8-shaped" structure with both ends open. During the use of the hinge assembly according to this embodiment, the first rotating shaft 10 and the second rotating shaft 20 and the torque adjustment sheet 71 frequently generate relative motion and generate dynamic friction. By using the torque adjustment sheet 71 formed into an "8-shaped" structure with both ends open as described above, part of the force can be unloaded, so that the service life of the torque adjustment sheet 71 can be increased while ensuring that the plurality of torque adjustment sheets 71 effectively clamp the first rotating shaft 10 and the second rotating shaft 20. In addition, in this embodiment, in order to ensure the balance of the hinge assembly, a plurality of torque adjustment sheets 71 are provided on both sides of the first rotating shaft 10 and the second rotating shaft 20.

[0106] In addition, the first torsion spring group 73 and the second torsion spring group 74 are respectively provided at both ends of the first rotating shaft 10 to change the torsion to be applied to the first rotating shaft 10, and the third torsion spring group 75 and the fourth torsion spring group 76 are respectively provided at both ends of the second rotating shaft 20.

[0107] For example, the structures of the four torsion spring leaf groups are the same, and only one of the torsion spring leaf groups is used as an example for description. Specifically, the first torsion spring leaf group 73 may include, for example, a plurality of disc spring leaves, that is, a plurality of disc spring leaves are closely stacked and assembled together, so as to provide a rotational torque to the first rotating shaft 10 on one side, that is, in the embodiment, the four torsion spring leaf groups are used as the main torque source.

[0108] In addition, if Figure 1 As shown, a fastening nut is screwed on the side of each torsion spring group opposite to the side where the corresponding torsion adjustment plate group is located, that is, the first torsion spring group 73, the second torsion spring group 74, the third torsion spring group 75 and the fourth torsion spring group 76 correspond one by one to the first fastening nut 77, the second fastening nut 78, the third fastening nut 79 and the fourth fastening nut 80.

[0109] In the embodiment, the first fastening nut 77 and the second fastening nut 78 are screwed on both ends of the first rotating shaft 10 to apply pressure to the first torsion spring set 73 and the second torsion spring set 74, and the third fastening nut 79 and the fourth fastening nut 80 are screwed on both ends of the second rotating shaft 20 to apply pressure to the third torsion spring set 75 and the fourth torsion spring set 76. For example, the corresponding fastening nuts can be screwed in to a specified or desired torque level by a tool such as a wrench.

[0110] In addition, it should be noted that the hinge assembly may further include at least one plate-shaped covering member (not shown) whose two ends respectively elastically and tightly cover the first rotating shaft and the second rotating shaft. However, according to actual design requirements, the biaxial hinge may only include a plate-shaped covering member instead of the above-mentioned torsion adjustment sheet, torsion spring leaf assembly and fastening nut.

[0111] In other words, the hinge assembly may include any one or a combination of a plurality of torsion adjustment plates, a plate-shaped covering member, a torsion spring set, and a fastening nut.

[0112] In addition, according to a second aspect of the present invention, there is provided a laptop computer, the laptop computer comprising a keyboard (not shown), a screen (not shown) and the hinge assembly as described above. In an embodiment, the screen is connected to the third rotation axis 30 via the first connecting plate 1, and the keyboard is connected to the second rotation axis 20 via the second connecting plate 2, wherein as Figures 1 to 6 As shown, the second connecting plate 2 consists of two parts.

[0113] In the embodiment, when the hinge assembly is transformed from the first posture to the second posture, the screen cannot rotate relative to the keyboard; in the second posture of the hinge assembly, the screen can pivot relative to the keyboard; when the hinge assembly is transformed from the second posture to the third posture, the screen cannot rotate relative to the keyboard. In other words, when the keyboard and the screen rotate 90 degrees relative to each other, the screen cannot rotate relative to the keyboard, which can prevent the screen and the keyboard from interfering with each other. Similarly, when the keyboard and the screen rotate from 90 degrees to 180 degrees relative to each other, the screen cannot rotate relative to the keyboard, which can prevent the screen and the keyboard from interfering with each other.

[0114] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
