A first aspect of the embodiments of the present application provides a hinge device, in which prior art prior to the present application a hinge device having an idler gear is generally required to be mounted into the hinge device using a dedicated mounting, and according to the principle of use of the idler gear, in prior art the idler gear is used between two gears, as an intermediary in the transmission of the two gears, the purpose of the idler gear is to make the rotation directions of the two gears the same, and not to change the transmission ratio in general. Taking the hinge device of the prior art having two shafts arranged side by side as an example (i.e., two gears are respectively provided to the two shafts), the idler pulley block generally includes a block body having two through holes respectively corresponding to the two shafts, the idler pulley block further includes two holding plates protruding from the block body opposite to each other, the two holding plates being opposite to each other in a direction perpendicular to an axial direction of the two shafts, and the two holding plates protruding from a portion of the block body between the two through holes, which allows the idler pulley to be accommodated therebetween. On this basis, the prior art further employs a pin disposed between two retaining plates to rotatably mount the idler gear, thus completing the limiting of the idler gear such that the idler gear is located between and simultaneously engaged with the two gears.

Prior to the present application, the above existing hinge apparatus has resulted in high production costs of the existing hinge apparatus due to the arrangement of the idler wheel mount. In view of this, the first aspect of the embodiment of the present application proposes the above hinge mechanism 1, and referring to fig. 1 to 5, the hinge mechanism 1 provided by the present embodiment includes the first shaft 10, the second shaft 20, the first plate 61, the second plate 62, the third plate 63, the first gear 30, the second gear 40, the idler gear 50, the torsion spring 71, the torsion washer 72, and the nut 73, and the structure and the operation principle of these components will be described in detail below.

Referring to fig. 1, similar to what has been mentioned in the above description, in the embodiment, both the first shaft 10 and the second shaft 20 may be disposed side by side, and as an example, both the first shaft 10 and the second shaft 20 may have the same structure, more specifically, in the hinge mechanism 1, the remaining components mounted on both the first shaft 10 and the second shaft 20 may also be the same, and in the following description, in describing the structure of both the first shaft 10 and the second shaft 20 and the remaining components mounted on both the first shaft 10 and the second shaft 20, description will be given by way of example for simplifying the description process.

Still referring to fig. 1 in combination with fig. 2, a schematic view of an exploded view of the hinge mechanism 1 given in fig. 1 is shown in fig. 2, where, referring in particular to fig. 2, in an embodiment, the first shaft 10 comprises a connecting portion 13, an intermediate portion 12 and a mounting portion 11 connected in sequence from the left side to the right side of the orientation shown in fig. 2, wherein the mounting portion 11 may be substantially stepped shaft-like, the mounting portion 11 comprising a relatively long mounting shaft section and a relatively short externally threaded shaft section (both not labeled in the figures) connected to each other. In an embodiment, the mounting shaft section is used to mount the above-mentioned first plate 61, second plate 62, third plate 63, gear, torsion spring 71 and torsion washer 72, and the externally threaded shaft section is used to cooperate with the above-mentioned nut 73 to secure the above-mentioned components. In an embodiment, the mounting shaft section may have a shape machined on a cylindrical basis with two planes opposite to each other (e.g., by turning), which facilitates synchronous rotation with the torsion spring 71 and the gear described below, which will be described later.

In an embodiment, referring to fig. 1 and 2, the intermediate portion 12 may include a cylindrical portion having a cross-sectional dimension larger than that of the mounting portion 11 so as to serve as a positioning shoulder for each component on the mounting shaft section, and a side of the intermediate portion 12 remote from the mounting shaft section, that is, a left side of the intermediate portion 12 in the drawing, is connected to the connecting portion 13. Still referring to fig. 1 and 2, in an embodiment, the connection portion 13 may include a plate-shaped portion, which may be provided with mounting holes, for example, a plurality of mounting holes, and in the examples given in fig. 1 to 5, the number of mounting holes is two, and here, two sets of mounting holes corresponding to the first shaft 10 and the second shaft 20, respectively, are used for connection with a first connection member 2a and a second connection member 2b, which will be described later, respectively.

As shown in fig. 1 and 2, in an embodiment, the first plate 61 and the second plate 62 may have the same structure, and referring to fig. 2 in particular, the first plate 61, the second plate 62 and the third plate 63 each include two through holes through which the first shaft 10 and the second shaft 20 pass, respectively, wherein the first plate 61 may include a first hole 61a provided at a region of the first plate 61 between the two through holes, and the first hole 61a may be a bar-shaped hole, as an example, and in an embodiment, the second plate 62 has the same structure as the first plate 61, and in an embodiment, the second plate 62 may include the same second hole 62a as the first plate 61, as mentioned above.

With further reference to fig. 1 and 2, in an embodiment, the first shaft 10 may be sequentially sleeved with a third plate 63, a torsion spring 71 (e.g., one torsion spring 71, in other examples, a plurality of torsion springs 71), a second plate 62, a first gear 30, a first plate 61, a set of torsion springs 71 including a plurality of torsion springs 71, a set of torsion springs 72 including a plurality of torsion springs 72, a torsion spring 71 (e.g., one torsion spring 71, in other examples, a plurality of torsion springs 71), and a nut 73. Similarly, the same is true for the components mounted on the second shaft 20, except that the second gear 40 is disposed on the second shaft 20 between the first plate 61 and the second plate 62. Because the first gear 30 and the second gear 40 are provided in a sleeved arrangement, rather than directly manufacturing (e.g., turning) a gear shaft with gears, the machining time of both the first shaft 10 and the second shaft 20 can be reduced by about half, because there is no need to re-machine the gear portions when machining the shafts, while also facilitating the disassembly of the first gear 30 and the second gear 40.

Referring to fig. 1 and 2, in the embodiment, an idler gear 50 is disposed between the first gear 30 and the second gear 40 and is engaged with both the first gear 30 and the second gear 40, and as an example, the axis of the idler gear 50 is perpendicular to the axis of the first gear 30 (the second gear 40). Here, referring to fig. 4, fig. 4 specifically shows the structure of the idler gear 50 in an isometric view, in an embodiment, the idler gear 50 may be provided in a generally stepped shaft shape, and in particular, the idler gear 50 may include an upper shaft section 52, a tooth portion 51, and a lower shaft section 53 disposed in order from top to bottom, wherein the upper shaft section 52 and the lower shaft section 53 may have the same diameter, the tooth portion 51 has an outer diameter larger than that of the upper shaft section 52 and the lower shaft section 53, and the tooth portion 51 is for forming engagement with both the first gear 30 and the second gear 40.

On this basis, with reference to fig. 1 and 2 and with particular reference to fig. 1, in an embodiment, the first hole 61a comprised by the first plate 61 and the second hole 62a comprised by the second plate 62 may be provided for receiving the portion of the tooth 51 of the idler wheel 50, that is to say, the width of both the first hole 61a and the second hole 62a may be slightly greater than the thickness of the tooth 51, so that a portion of the idler wheel 50 can be received in the first hole 61a and a further portion of the idler wheel 50 can be received in the second hole 62a, such that the idler wheel 50 is restrained between the first plate 61 and the second plate 62 and still able to rotate, i.e. while keeping itself rotatable, the hinge mechanism 1 provided in this embodiment does not need to be provided with a wheel seat for holding the idler wheel 50, so that the cost of the hinge mechanism 1 is greatly reduced in terms of parts, and the assembly time of one idler wheel seat can be reduced in the set of the hinge mechanism 1, and in addition, the first and second plates 61 and 62 are provided in a more compact configuration, i.e. the hinge mechanism 10 is provided in this embodiment, with respect to the first plate 61 and the first plate 62, and the second plate 1.

Referring further to fig. 2, in the embodiment, each of the first plate 61, the second plate 62 and the third plate 63 is provided with a plurality of grooves on both sides in the axial direction of the first shaft 10, where the plurality of grooves are provided around the through holes through which the first shaft 10 and the second shaft 20 pass, that is, a part of the grooves are provided around the groove of each through which the first shaft 10 passes, and another part of the grooves are provided around the groove of each through which the second shaft 20 passes. Similarly, the torsion spring 71 disposed between the second plate 62 and the third plate 63 is also provided with a plurality of grooves on both sides thereof in the axial direction (i.e., both sides in the axial direction of the first shaft 10), and these grooves are disposed in a manner similar to the first plate 61, the second plate 62 and the third plate 63, and will not be repeated again. In an embodiment, these grooves are used to store grease to lubricate the relative rotation between the components, as will be described later.

In the embodiment shown in fig. 2, the hole portion formed in the torsion spring 71 is adapted to the shape of the cross section of the mounting shaft section, and the torsion spring 71 may have such a hole portion in combination with the schematic views of the hole portions of both the first gear 30 and the second gear 40 given in fig. 3. Thus, in the embodiment, the torsion reed 71 and the first gear 30 corresponding to the first shaft 10 are both interlocked with the first shaft 10, and the torsion reed 71 and the second gear 40 corresponding to the second shaft 20 are interlocked with the second shaft 20, so that the torsion reed 71 provided between the second plate 62 and the third plate 63 is relatively rotated with both the second plate 62 and the third plate 63, and each of the first gear 30 and the second gear 40 is relatively rotated with both the first plate 61 and the second plate 62, and thus the grease previously stored in the grooves as above is being used to lubricate these relative rotation movements.

Still referring to fig. 2, in addition, part of torsion spring 71 of the set of torsion spring 71 disposed outside first plate 61 and torsion spring 71 adjacent to nut 73 may also be provided with the above groove and store grease in the manner as above, and further torsion washer 72 is provided with a circular through hole.

A second aspect of the embodiments of the present application provides a connection device, including the hinge mechanism 1 as described above, as shown in fig. 5, and further including a first connection member 2a connected to the mounting portion 11 of the first shaft 10 of the hinge mechanism 1 and a second connection member 2b connected to the mounting portion 11 of the second shaft 20 of the hinge mechanism 1, for example, a through hole corresponding to a through hole on the mounting portion 11 corresponding to the connection member is formed in a corresponding connection member, the connection member and the mounting portion 11 corresponding to the connection member are connected by a pin, wherein the first connection member 2a may be used for connection with a display device (for example, a display), and the second connection member 2b may be used for connection with an input device (for example, a keyboard).

A third aspect of the embodiments of the present application provides an electronic device, including a connection device as above, where the connection device further includes a display device and an input device, which are not shown in the drawings, and a specific example of the connection device and a matching manner with the connection device are described in the foregoing description, which is not repeated herein.

The foregoing description is only of the preferred embodiments of the present application, and is not intended to limit the scope of the present application, but rather, the present application is intended to cover any variations of the equivalent structures described herein or shown in the drawings, or the direct/indirect application of the present application in other related fields.
