Referring to fig. 1A to fig. 1C, the hinge module 100 of the present invention is suitable for use in an electronic device 200. The electronic device 200 is, for example, a notebook computer, a tablet computer or other similar products. The electronic device 200 includes a first body 210, a bracket 220, a second body 230, and a hinge module 100. The first body 210 is, for example, a logical body. The second body 230 is, for example, a display body and is disposed on the bracket 220, and the pivot module 100 is disposed between the first body 210 and the bracket 220, so that the bracket 220 is rotatably connected to the first body 210. The electronic device 200 is suitable for being switched into a closed state and an expanded state. Referring to fig. 1C, in the closed state (see fig. 1C), the bracket 220 is overlapped on the first body 210 in parallel, which reduces the volume of the electronic device 200 for easy storage. Referring to fig. 2A and 3A, in the unfolded state, the first body 210 and the bracket 220 are unfolded relatively through the pivot module 100 and have an included angle a, which freely adjusts the unfolding angle of the bracket 220 according to the use requirement, thereby adjusting the viewing angle of the second body 230 toward the user, so as to facilitate the work and use.

Referring to fig. 1A and 1B, the pivot module 100 of the present invention includes a limiting seat 110, a sliding seat 120, at least one link assembly 130, and a rotating shaft 140.

The position-limiting base 110 is fixedly disposed on the top surface TS of the first body 210. In detail, the position-limiting base 110 has two fixing plates 111 respectively disposed on two parallel sides of the position-limiting base 110, and further includes a plurality of locking members SP respectively penetrating through the two fixing plates 111 and locked on the top surface TS of the first body 210, so as to ensure that the position-limiting base 110 and the first body 210 are connected together.

The sliding seat 120 is movably disposed on the position-limiting seat 110, which means that the sliding seat 120 is suitable for reciprocating on the position-limiting seat 110, and can move linearly in a first direction D1 or move linearly in a second direction D2 opposite to the first direction D1. The at least one link assembly 130 is connected to the limiting seat 110 and the sliding seat 120, respectively, wherein the at least one link assembly 130 is used for transmitting an external force and driving the sliding seat 120 to displace. The rotating shaft 140 penetrates through the at least one link assembly 130 and the sliding seat 120, and the rotating shaft 140 is connected to the bracket 220.

Referring to fig. 1C, fig. 2A and fig. 3A, when the first body 210 and the bracket 220 move relatively (i.e., expand or close relatively), the bracket 220 drives the rotating shaft 140 to rotate relative to the sliding seat 120 and applies a force to the at least one link assembly 130 to drive the sliding seat 120 to move along the limiting seat 110, and is switched to a closed state (see fig. 1A) or an expanded state (see fig. 2A and fig. 3A).

Referring to fig. 1A, 1B, 2B and 3B, in the present embodiment, the position-limiting base 110 has a sliding slot SG, and a recess is formed on the surface OS of the position-limiting base 110. The sliding base 120 has a sliding rail SR formed on the bottom surface BS of the sliding base 120, the sliding rail SR is movably disposed in the sliding slot SG, and the sliding rail SR is adapted to move linearly along the sliding slot SG. The sliding groove SG is, for example, in a dovetail groove form, that is, the inner diameter of the sliding groove SG is gradually reduced toward the surface OS, the outer diameter of the sliding rail SR is gradually increased away from the bottom surface BS, and the gradually reduced inner diameter of the sliding groove SG is suitable for matching with the gradually increased outer diameter of the sliding rail SR, so as to limit the sliding rail SR to move only along the sliding groove SG and avoid the mutual falling-off.

In other embodiments, the sliding groove is formed on the bottom surface of the sliding seat and the sliding rail is formed on the top surface of the limiting seat, and the sliding groove of the sliding seat is movably sleeved on the sliding rail of the limiting seat, so that the effect of linear movement can be achieved.

Referring to fig. 1A to 1C, further, the sliding seat 120 has a pivot portion 121 formed at a second end E2 of the sliding seat 120 opposite to the first end E1.

The rotating shaft 140 includes an installation portion 141, a turning portion 142, a stopper 143, and an extension portion 144.

The mounting portions 141 face-contact the bracket 220 and are lockingly attached to each other. The turning portion 142 is formed at one end of the mounting portion 141 to extend and rotatably pass through the pivot portion 121 of the sliding seat 120. The stopping portion 143 is formed around the turning portion 142 and abuts the mounting portion 141. The extending portion 144 is formed at an end of the turning portion 142 opposite to the mounting portion 141, the extending portion 144 protrudes out of the pivot portion 121 of the sliding seat 120, and the torsion member 150 is sleeved on the extending portion 144 and contacts at least one link assembly 130.

In addition, the torsion element 150 is adapted to apply a force to the pivoting portion 121 of the at least one link assembly 130 and the sliding seat 120, so that the torsion element 150 and the stopping portion 143 bidirectionally clamp the at least one link assembly 130 and the pivoting portion 121 to provide a torsion force during steering, thereby fixing the unfolding angle of the bracket 220.

Referring to fig. 1A and 1B, the limiting base 110 has two driving plates 112 disposed on the surface OS of the limiting base 110 at intervals and located at two sides of the sliding slot SG, at least one connecting rod assembly 130 includes two connecting rod assemblies 130, the two connecting rod assemblies 130 are respectively pivoted to the two driving plates 112 and sleeved on the turning portion 142 of the rotating shaft 140, and the two connecting rod assemblies 130 are respectively located at two sides of the pivoting portion 121. The two link assemblies 130 apply force synchronously on two sides of the pivot portion 121 to ensure the stability of the sliding seat 120 moving on the limiting seat 110.

Each link assembly 130 includes a first link 131 and a second link 132, each first link 131 is pivotally connected to each driving plate 112, and both ends of each second link 132 are respectively pivotally connected to each first link 131 and a steering portion 142 rotatably sleeved on the rotating shaft 140.

Further, referring to fig. 1A and 1C, when the first body 210 and the bracket 220 are switched to the closed state, a first height H1 of the first link 131 and the second link 132 relative to the top surface TS of the first body 210 is lower than a second height H2 of the heat dissipation area HP relative to the top surface TS. Referring to fig. 2A, when the bracket 220 is unfolded 30 degrees relative to the first body 210, the connection point of the first link 131 and the second link 132 moves upward, so that a first height H1 of the first link 131 and the second link 132 relative to the top surface TS of the first body 210 is higher than a second height H2 of the heat dissipation area HP relative to the top surface TS. Referring to fig. 3A, when the first body 210 and the bracket 220 are switched to the unfolded state, the second link 132 is rotatably located below the first link 131 along with the movement of the sliding seat 120.

Referring to fig. 1A to 1C, when the first body 210 and the bracket 220 are closed, the bracket 220 drives the rotating shaft 140 to rotate in the first rotating direction T1 and swing toward the first body 210, and at least one link assembly 130 drives the sliding seat 120 to move in the first direction D1 along the limiting seat 110 to gradually approach the heat dissipation area HP of the first body 210, wherein the first end E1 of the sliding seat 120 is located above the limiting seat 110, and the bracket 220 moves along with the sliding seat 120 and enters the accommodating groove AG of the first body 210, thereby achieving the effect of reducing the volume of the electronic device 200.

Referring to fig. 2A to 3B, when the first body 210 and the bracket 220 are in the expanded state, the bracket 220 drives the rotating shaft 140 to rotate in the second rotating direction T2 and swing away from the first body 210, and at least one link assembly 130 drives the sliding seat 120 to move along the limiting seat 110 in the second direction D2 so as to gradually get away from the heat dissipation area HP of the first body 210, wherein the first end E1 of the sliding seat 120 protrudes out of the limiting seat 110, the bracket 220 moves along with the sliding seat 120 and gets away from the receiving groove AG of the first body 210, and finally a gap GP is formed between the bracket 220 and the first body 210, and the gap GP can be used as a flow channel of air, so as to improve the heat dissipation efficiency of the electronic device 200 in the operating mode.

Since the sliding seat 120 is adapted to move in the first direction D1 or the second direction D2 when the first body 210 and the bracket 220 are closed or opened, the linear distance between the bracket 220 and the accommodating groove AG can be adjusted to avoid interference between the first body 210 and the bracket 220.

In summary, the pivot module of the present invention is suitable for being switched to the closed state or the expanded state, when an external force is applied to the rotating shaft to rotate relative to the sliding seat, the rotating shaft applies a force to the at least one link assembly to drive the sliding seat to move along the limiting seat, so as to achieve the effect of moving synchronously during the rotating process.
