Background

In order to facilitate the user to write on the screen or display the picture, most of the electronic devices on the market have a screen end (e.g., the pen screen) and a system end (e.g., the pen keyboard) pivotally swing from a closed state (e.g., the pen screen and the pen keyboard are folded up and down and face each other) to an inverted state (e.g., the pen screen and the pen keyboard are folded up and down and face opposite directions) through a pivotal connection structure.

However, when the screen end and the system end are pivoted from the closed state to the folded state through the existing pivoting structure, the screen end and the system end are mostly pivoted by 180 degrees at the same time, but the frame of the existing pivoting structure is hindered, so that the front and rear edges of the screen end and the front and rear edges of the system end cannot be flush in the folded state and have obvious front and rear section differences, which is not only unattractive but also inconvenient to operate and use.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 to 10, the present embodiment provides an electronic device 100. As shown in fig. 1, the electronic device 100 includes a first electronic component 1, a second electronic component 2, and two pivot structures 3 connecting the first electronic component 1 and the second electronic component 2.

It should be noted that the first electronic component 1, the second electronic component 2, and the two hinge structures 3 are collectively defined as the electronic device 100 in the present embodiment. But the present creation is not limited thereto. For example, a single pivot structure 3 may be used alone (e.g., implemented, manufactured, sold, etc.) or in combination with other components. The following describes the structure of each element of the electronic device 100, and describes the connection relationship between the elements of the electronic device 100.

As shown in fig. 1, the first electronic component 1 and the second electronic component 2 are respectively plate-shaped structures, and the first electronic component 1 is an operation screen (or screen end) in this embodiment, and the second electronic component 2 is a keyboard (or system end) of a built-in system hardware. The first electronic component 1 and the second electronic component 2 are electrically coupled to each other, so that the first electronic component 1 can display the system, the instruction and other images of the second electronic component 2. In other words, the electronic device 100 is illustrated in the embodiment as a pen-type device, but the present disclosure is not limited thereto. For example, in other embodiments not shown, the electronic device 100 may also be a foldable keyboard for a tablet.

As shown in fig. 2 to 4, the two pivoting structures 3 are respectively connected to the first electronic component 1 and the second electronic component 2, so that the first electronic component 1 and the second electronic component 2 can pivot and swing simultaneously. Each of the pivoting structures 3 includes a housing 31, two shafts 32, a limiting component 33 disposed on the two shafts 32, two mounting members 34 respectively mounted on the two shafts 32, and a transmission unit 35 pivoted to the limiting component 33.

As shown in fig. 3 to 5, the housing 31 is hollow in the embodiment and can be used to accommodate parts of the two shafts 32, the limiting component 33, and the transmission unit 35, but the present invention is not limited thereto. For example, in other embodiments not shown, the case 31 may be omitted.

As shown in fig. 4 to 6, each of the shafts 32 has a gear portion 321 and a shaft portion 322. The gear portions 321 of the two shaft rods 32 are formed by extending from the outer edge of the corresponding shaft body 322, and the two gear portions 321 are each in a helical gear shape, that is, the gear portion 321 and the shaft body 322 of each shaft rod 32 together form a single component in the present embodiment, but the present invention is not limited thereto. For example, the gear portion 321 and the shaft portion 322 of each shaft 32 may be two independent members.

In addition, the gear ratio between the gear portions 321 of the two shafts 32 is not equal to 1, that is, the diameter of the gear portion 321 of one of the shafts 32 is larger than that of the gear portion 321 of the other shaft 32, so that the two shafts 32 can be simultaneously driven by the transmission unit 35 to pivot at different speeds (i.e., the two shafts have different angular velocities during rotation).

The position limiting assembly 33 is disposed on the two shaft portions 322, and the position limiting assembly 33 can maintain the two shafts 32 to be spaced apart from each other and to be parallel to each other. Specifically, the limiting component 33 in this embodiment includes two

support plates

331A and 331B and two configuration plates 332, each of the

support plates

331A and 331B is disposed on two of the shaft portions 322, and the two

support plates

331A and 331B are respectively located on two common sides of the two gear portions 321.

In practical applications, the two

support plates

331A, 331B may be disposed parallel to each other and perpendicular to the two shafts 32, but the present disclosure is not limited thereto. For example, in other embodiments not shown, the two

support plates

331A and 331B may not be parallel to each other, or one of the support plates may not be perpendicular to the two shafts 32.

In more detail, each of the supporting

plates

331A, 331B has a first pivot hole H1 and a second pivot hole H2 disposed at an interval, the first pivot hole H1 of the two supporting

plates

331A, 331B is capable of pivotally connecting (the shaft portion 322 of) one of the shafts 32, the second pivot hole H2 of the two supporting

plates

331A, 331B is capable of pivotally connecting (the shaft portion 322 of) the other shaft 32, so that the two shafts 32 are maintained by the two supporting

plates

331A, 331B in a spaced and parallel arrangement.

It should be noted that the two

support plates

331A and 331B are based on assembly requirements in the present embodiment, and thus the two

support plates

331A and 331B have a slight difference. Specifically, the supporting plate 331A is used for two of the shaft levers 32 to penetrate therethrough, and the supporting plate 331B is assembled on the two shaft levers 32 in a snap-fit manner when the two shaft levers 32 penetrate through the supporting plate 331A, so that the two supporting

plates

331A and 331B can limit the two shaft levers 32.

As shown in fig. 4 to 6, two of the configuration plates 332 connect two sides of at least one of the support plates, and the two configuration plates 332 are not parallel to the two

support plates

331A and 331B. In this embodiment, the two configuration plates 332 are formed by extending from the support plate 331A to the other support plate 331B, and are perpendicular to the two

support plates

331A and 331B. The two arrangement plates 332 are located at positions corresponding to positions between the two gear portions 321 for the arrangement of the transmission unit 35. Of course, two of the configuration plates 332 may be a case-adjusted number (e.g., only one of the configuration plates 332) or omitted.

Referring to fig. 4 to 6 again, the two mounting members 34 are plate-shaped in this embodiment, and the two mounting members 34 are respectively fixed to the shaft portions 322 of the two shafts 32. The first electronic component 1 and the second electronic component 2 are respectively mounted on the two mounting members 34, so that each of the mounting members 34 can drive the first electronic component 1 and the second electronic component 2 to pivot around the corresponding shaft 32. In addition, when the first electronic component 1 and the second electronic component 2 are respectively mounted on the two mounting parts 34, the first electronic component 1 and the second electronic component 2 are parallel to the corresponding mounting parts 34.

As shown in fig. 4 to 6, the transmission unit 35 is pivotally connected to the position-limiting component 33 and engages with the two gear portions 321. When the gear portion 321 of any one of the shafts 32 rotates, the transmission unit 35 can be driven to simultaneously transmit the gear portion 321 of the other shaft 32 to rotate, so that the two mounting members 34 can pivot oppositely to each other between a first position PL1 and a second position PL2 with the corresponding shaft 32 as an axis (as shown in fig. 6 to 8).

In the present embodiment, the transmission unit 35 includes a helical gear 351 and a rotation shaft 352, the rotation shaft 352 is pivoted on the two arrangement plates 332 and is not parallel to the two shaft rods 32 (for example, the rotation shaft 352 is perpendicular to the two shaft rods 32, or an included angle of 45 degrees is formed between the rotation shaft 352 and any one of the shaft rods 32). The helical gear member 351 is fixed to the rotation shaft 352, and the helical gear member 351 engages with the two gear portions 321, so that the helical gear member 351 can transmit the two gear portions 321 to pivot in opposite directions to each other, but the present invention is not limited thereto.

For example, in another embodiment shown in fig. 10, the transmission unit 35 'may also include two spur gear members 353 and two rotation shafts 352', each of the rotation shafts 352 'is pivotally connected to two of the support plates 331A and 311B, and the two rotation shafts 352' are parallel to two of the shafts 32. The two spur gear members 353 are respectively fixed on the two rotating shafts 352' and meshed with each other, so that the two spur gear members 353 can drive the two gear portions 321 to pivot in opposite directions, thereby moving the two mounting members 34 between the first position PL1 and the second position PL 2. In other words, the transmission unit 35 can be adjusted according to the designer's requirement, and the position-limiting assembly 33 is also the same (for example, two of the configuration plates 332 are omitted).

In addition, it should be noted that when the transmission unit 35 transmits the two mounting members to the first position PL1 (shown in fig. 6), the two mounting members 34 are overlapped and parallel to each other; when the driving unit 35 drives the two mounting members to the second position PL2 (shown in fig. 8), the two mounting members 34 are also overlapped and parallel to each other, and a minimum included angle (i.e., the angle of θ 1 and 180- θ 2 in fig. 8) between the first position PL1 and the second position PL2 of any one of the mounting members 34 is between 90 degrees and 180 degrees.

That is, in the 360-degree pivoting angle of the two mounting members, only the first position PL1 and the second position PL2 of the two mounting members can be overlapped and parallel to each other. In addition, when the two mounting elements 34 are located at the first position PL1 (or the second position PL2), a longitudinal direction DL of each mounting element 34 is not perpendicular to a configuration line AL formed by connecting centers of the corresponding first pivot hole H1 and the second pivot hole H2. That is, the longitudinal direction DL of any one of the mounting pieces 34 located at the first position PL1 (or the second position PL2) is not perpendicular to the arrangement line AL.

In a more detailed view, when viewed from a perspective facing the axial centers of the two shafts 32, a position of one of the two mounting members 34 when they are overlapped with each other and parallel to each other is defined as the first position PL1 (as shown in fig. 6), and the two mounting members 34 are not perpendicular to the arrangement line AL; when the two mounting members 34 located at the first position PL1 pivot about the corresponding shafts 32 (as shown in fig. 7), the two mounting members 34 can pivot at different speeds in the clockwise direction and the counterclockwise direction (by the technical feature that the gear ratio is not 1), and the sum of the pivoting angles of the two mounting members 34 is 360 degrees; when the two mounting members 34 are pivoted to another position (shown in fig. 8) which is overlapped and parallel to each other, the position of the two mounting members 34 is the second position PL2, and the two mounting members 34 are not perpendicular to the arrangement line AL.

Of course, the non-perpendicular configuration relationship between the configuration line AL on each of the

support plates

331A and 331B and the longitudinal direction DL of the two mounting members 34 is only one embodiment of the present invention, and the present invention is not limited thereto. For example, in other embodiments not shown, the configuration line AL on the support plate 331 and the length direction DL of the two mounting members 34 may be in a perpendicular configuration relationship.

As shown in fig. 9, since the first electronic component 1 and the second electronic component 2 are mounted on the two mounting members 34 and are parallel to the corresponding mounting members 34, the first electronic component 1 and the second electronic component 2 can also pivot between the first position PL1 and the second position PL2 with the two mounting members 34.

In addition, when the first electronic component 1 and the second electronic component 2 located at the first position PL1 are brought to the second position PL2 by the two pivot structures 3, the angular velocity difference (i.e. the gear ratio is not equal to 1) of the first electronic component 1 and the second electronic component 2 passing through the two gear portions 321 is such that the minimum included angle (i.e. the angle θ 1 and 180- θ 2 in fig. 8) between the first position PL1 and the second position PL2 of the first electronic component 1 or the second electronic component 2 is between 90 degrees and 180 degrees.

Accordingly, the electronic device 100 and the hinge structure 3 of the present disclosure can effectively reduce the front-back section difference L (as shown in fig. 9) between the first electronic component 1 and the second electronic component 2 in the overlapped and parallel position, compared with the conventional hinge structure with the same angular velocity (i.e., the gear ratio is 1), thereby further improving the advantages of beauty and convenience in operation.

It should be noted that, in the preferred embodiment, the minimum included angle is preferably designed to be between 166.5 degrees and 171.5 degrees, which enables the front-back step L between the first electronic component 1 and the second electronic component 2 to be reduced to the minimum. In the frame designed with the minimum angle between 166.5 degrees and 171.5 degrees, the gear between the two gear portions 321 is preferably between 1 to 1.14, but the present invention is not limited thereto.

In addition, in practical applications, the pivot structure 3 may require a resistance adjustment component 36 to be mounted on the two shaft rods 32, and the resistance adjustment component 36 can be used to adjust the resistance of the two shaft rods 32 during pivoting, so as to enable a user to have a better operation feeling when pivoting the first electronic component 1 and the second electronic component 2. The resistance adjusting assembly 36 is prior art and is not the technical focus of the present invention, and will not be described in detail herein.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
