Description

Technical Field

[0001] The invention relates to a hinge module, and in particular to a hinge module and an electronic device. Background Art

[0002] The existing hinge module is often used in laptop computers. The hinge module is connected between the host and the display body of the laptop computer, so that the host and the display body can be relatively expanded or relatively closed to switch between the working mode and the storage mode. However, in order to achieve the purpose of flipping the laptop computer, a gap must be reserved between the host and the display body to avoid interference between the host and the display body during the flipping process.

[0003] When the notebook computer is switched to working mode and the angle between the display body and the host is greater than 90 degrees, the display body will be away from the user and the center of gravity will shift backwards, which will cause the problem of easy tipping and occupying a large space. Summary of the invention

[0004] The present invention is directed to a hinge module which has the function of being unfolded in two stages and is used to be combined with an electronic device. When the electronic device is unfolded, its screen can be suspended above the host to achieve the purpose of shortening the distance with the user.

[0005] The hinge module of the present invention includes a positioning assembly, a first rotating shaft, a second rotating shaft, a first bracket, a second bracket and a switching assembly. The first rotating shaft has a first steering portion and a first mounting portion. The first steering portion is rotatably arranged in the positioning assembly. The second rotating shaft has a second steering portion and a second mounting portion. The second steering portion is rotatably arranged in the positioning assembly. The first bracket is arranged at the first mounting portion of the first rotating shaft. The second bracket is arranged at the second mounting portion of the second rotating shaft. The switching assembly is movably arranged in the positioning assembly and is located between the first rotating shaft and the second rotating shaft. In the closed state, the first bracket is parallel to the second bracket. In the first unfolded state, the second rotating shaft drives the positioning assembly to rotate relative to the first rotating shaft through the switching assembly, so that the first bracket and the second bracket have a first angle. In the second unfolded state, the second rotating shaft rotates relative to the positioning assembly and pushes the switching assembly, so that the first bracket and the second bracket have a second angle.

[0006] The electronic device of the present invention comprises a first body, a second body, a hinge cover and two hinge modules. The first body has a first groove. The second body has a second groove. The hinge cover is arranged between the first groove and the second groove. The two hinge modules are arranged at opposite ends of the hinge cover respectively. Each hinge module comprises a positioning assembly, a first rotating shaft, a second rotating shaft, a first bracket, a second bracket and a switching assembly. The first rotating shaft has a first steering portion and a first mounting portion. The first steering portion is rotatably arranged in the positioning assembly. The second rotating shaft has a second steering portion and a second mounting portion. The second steering portion is rotatably arranged in the positioning assembly. The first bracket is arranged at the first mounting portion of the first rotating shaft and connected to the first body. The second bracket is arranged at the second mounting portion of the second rotating shaft and connected to the second body. The switching assembly is movably arranged in the positioning assembly and is located between the first rotating shaft and the second rotating shaft. In the closed state, the first body is parallel to the second body. In the first unfolded state, the second shaft drives the positioning assembly and the shaft cover to rotate relative to the first shaft through the switching assembly, so that the first body and the second body have a first angle. In the second unfolded state, the second body drives the second shaft to rotate relative to the positioning assembly and the shaft cover, so that the first body and the second body have a second angle and the second body is suspended on the first body.

[0007] Based on the above, the hinge module of the present invention has a first hinge and a second hinge. In the first expanded state, the second hinge and the switching component drive the positioning component to rotate relative to the first hinge, so that the first bracket and the second bracket are expanded to a first angle with each other. Then, in the second expanded state, since the positioning component is restricted by the first hinge, the second hinge rotates relative to the positioning component and pushes the switching component to make the second bracket continue to rotate and form a second angle with the first bracket.

[0008] Furthermore, the first body and the second body of the electronic device of the present invention are connected to the corresponding first bracket and the second bracket respectively. When the first body and the second body are switched to the second unfolded state, the second body is suspended above the host, and its position and the center of gravity of the second body are adjusted toward the user, which can slightly shorten the distance between the second body and the user compared to the existing laptop computer. In addition, the forward shift of the center of gravity can reduce the situation where the electronic device is prone to tipping backwards in the unfolded state. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] Mate Reference Figure 2D and Figure 2E The switching component 160 is movably disposed in the first positioning frame 111 and the second positioning frame 112 of the positioning component 110 and has two ends respectively abutting against the first rotating shaft 120 and the second rotating shaft 130 .

[0086] The two torque members 170 are sleeved on the first turning portion 121 and the second turning portion 131 to provide a torque when the first rotating shaft 120 and the second rotating shaft 130 rotate. When the first rotating shaft 120 and the second rotating shaft 130 are stationary, there is a static friction force between the two torque members 170 and the first turning portion 121 and the second turning portion 131 to prevent the first rotating shaft 120 and the second rotating shaft 130 from turning randomly. Figure 1D , Figure 2D and Figure 2E One torque member 170 is located between the second positioning frame 112 and the third positioning frame 113 , and the other torque member 170 is adjacent to the third positioning frame 113 and the fourth positioning frame 114 .

[0087] refer to FIG. 2A to FIG. 2C The first positioning frame 111 of the positioning assembly 110 has two sleeves ST, which are respectively sleeved on the first rotating shaft 120 and the second rotating shaft 130 and are respectively adjacent to the first driving part 123 and the second driving part 133, so that the first rotating shaft 120 and the second rotating shaft 130 are suitable for relative rotation in the two sleeves ST. The second positioning frame 112 is sleeved on the first turning part 121 and the second turning part 131. The lower blocking block LB and the upper blocking block TB of the second positioning frame 112 are respectively slidably disposed in the first sliding groove SG1 of the first driving part 123 and the second sliding groove SG2 of the second driving part 133.

[0088] The lower blocking block LB is fixed on the second positioning frame 112 and is suitable for sliding along the first sliding groove SG1. The first rotating shaft 120 is fixed, and the second positioning frame 112 is suitable for driving the lower blocking block LB to slide relative to the first driving part 123.

[0089] The upper blocking block TB is fixed on the second positioning frame 112 and is suitable for sliding along the second slide groove SG2. When the second rotating shaft 130 rotates, the upper blocking block TB is fixed, and the second rotating shaft 130 is suitable for driving the second driving part 133 to slide relative to the upper blocking block TB. The third positioning frame 113 is sleeved on the first turning part 121 and the second turning part 131 and is spaced from the second positioning frame 112.

[0090] refer to FIG. 2A to FIG. 2D The switch assembly 160 has a push rod 161 and a slider 162. The push rod 161 abuts against the second driving portion 133, and the slider 162 abuts against the first driving portion 123, and the push rod 161 and the slider 162 abut against each other. The push rod 161 is suitable for sliding relative to the first positioning frame 111 and the second positioning frame 112 along the first direction D1, so that the slider 162 slides relative to the first positioning frame 111 and the second positioning frame 112 along the second direction D2. There is an angle between the first direction D1 and the second direction D2, and they are perpendicular to each other, for example.

[0091] In detail, the push rod 161 has a driving portion DP, a guiding portion GP, ​​and an active inclined surface AS. The driving portion DP is formed at one end of the push rod 161 abutting against the second driving portion 133, the guiding portion GP is formed at the other end of the push rod 161 away from the second driving portion 133, and the active inclined surface AS is formed at the other end of the push rod 161 and adjacent to the guiding portion GP. The slider 162 has a driven inclined surface PS and a snap-fit ​​portion FP. The active inclined surface AS and the driven inclined surface PS are in contact with each other, and the snap-fit ​​portion FP abuts against the first driving portion 123.

[0092] refer to FIG. 2A to FIG. 2DThe first positioning frame 111 has two first direction grooves HG1 and a second direction groove VG1, wherein one first direction groove HG1 is close to the second rotating shaft 130, and the second direction groove VG1 is close to the first rotating shaft 120. The second positioning frame 112 has two first direction grooves HG2, a second direction groove VG2 and a guide hole GO, each first direction groove HG2 and second direction groove VG2 is aligned with the corresponding first direction groove HG1 and second direction groove VG1. The guide hole GO runs through both sides of the second positioning frame 112 and is used to accommodate the guide portion GP of the push rod 161.

[0093] Mate Reference Figure 2D and Figure 2E The multiple bosses C1 of the push rod 161 are slidably disposed in the two first direction grooves HG1 and the two first direction grooves HG2, so the multiple bosses C1 of the push rod 161 are suitable for sliding along the first direction D1 in the two first direction grooves HG1 and the two first direction grooves HG2, and the guide portion GP of the push rod 161 also slides in the guide hole GO along the first direction D1.

Figure 3B yes Figure 1B A schematic cross-sectional view of the electronic device along line segment BB. Figure 3C yes Figure 1C Schematic cross-sectional view of the electronic device along line segment CC.

[0095] refer to Figure 1A , Figure 2D and Figure 3A In the closed state, the second body 220 rotates in the first rotation direction T1 and is parallel to the first body 210, and one end of the shaft cover 230 is received in the second groove G2. At this time, the angle A between the second body 220 and the shaft cover 230 is 180 degrees. The driving portion DP of the push rod 161 is engaged with the second groove FG2 of the second driving portion 133 and is spaced D from the second positioning frame 112. At the same time, the engaging portion FP of the slider 162 abuts against the outer annular surface OS of the first driving portion 123 and is misaligned with the first groove FG1. The extension direction ED of the first groove FG1 has an angle B of 120 degrees with the first bracket 140 and the first body 210. The lower blocking block LB of the second positioning frame 112 abuts against the side of the first slide groove SG1 away from the engaging portion FP, and the upper blocking block TB of the second positioning frame 112 abuts against the side of the second slide groove SG2 adjacent to the driving portion DP.

[0096] refer to Figure 1B and Figure 3B In the first unfolded state, the angle A between the second body 220 and the rotating shaft cover 230 is still 180 degrees, and the second body 220 drives the rotating shaft cover 230 to unfold relative to the first body 210 with the first rotating shaft 120 as the axis (rotate in the second rotating direction T2 opposite to the first rotating direction T1). In detail, the second body 220 and the second rotating shaft 130 drive the positioning assembly 110 and the rotating shaft cover 230 to rotate relative to the first rotating shaft 120 through the switching assembly 160, so that the first body 210 and the second body 220 have a first angle A1 (for example, 30 degrees).

[0097] At this time, the driving portion DP of the push rod 161 is engaged with the second slot FG2 of the second driving portion 133, so the second rotating shaft 130 and the push rod 161 are connected as a whole to drive the positioning assembly 110 to rotate relative to the first rotating shaft 120, so that the engaging portion FP of the slider 162 leaves the outer annular surface OS and is aligned with the first slot FG1 of the first driving portion 123. At the same time, the lower blocking block LB of the second positioning frame 112 abuts against the other side of the first sliding groove SG1 close to the engaging portion FP to limit the rotating shaft cover 230 at a certain point.

[0098] refer to Figure 1C , Figure 2E and Figure 3B , Figure 3C When the second body 220 continues to apply force and drives the second shaft 130 to rotate relative to the positioning assembly 110 and the shaft cover 230, the first unfolded state is switched to the second unfolded state. In the second unfolded state, the first body 210 and the second body 220 have a second angle A2 (for example, 130 degrees) and the second body 220 is suspended on the first body 210.

[0099] In detail, in the second unfolded state, the second shaft 130 rotates in the second rotation direction T2 and pushes the driving portion DP of the push rod 161, so that the driving portion DP of the push rod 161 gradually leaves the second slot FG2 and abuts against the outer annular surface OS of the second driving portion 133. At the same time, the second body 220 rotates in the second rotation direction T2 relative to the shaft cover 230, so that the angle A between the second body 220 and the shaft cover 230 gradually decreases (less than 90 degrees). The outer annular surface OS of the second driving portion 133 pushes the driving portion DP of the push rod 161, so that the push rod 161 slides along the first direction D1 and approaches the second positioning frame 112 to reduce the distance D. The upper blocking block TB abuts against the other side of the second slide groove SG2 away from the driving portion DP to limit the second body 220 at a certain point. At the same time, the guide portion GP gradually slides into the guide hole GO. Then the active inclined surface AS of the push rod 161 pushes the driven inclined surface PS of the slider 162, so that the engaging portion FP of the slider 162 slides along the second direction D2 and engages with the first engaging groove FG1 of the first driving portion 123.

[0100] In short, the hinge module of the present invention has a two-stage switching function. In the first stage switching process (first unfolded state), the second body 220, the hinge cover 230 and the hinge module 100 rotate synchronously to unfold relative to the first body 210. The hinge cover 230 and the hinge module 100 adopt an L-shaped structure, so that the second body 220 and the hinge cover 230 can be stacked on each other, so that the hinge cover 230 and the hinge module 100 are stored in the second groove G2, thereby avoiding mutual interference between the hinge cover 230 and the second body 220 and reducing the size of the electronic device after unfolding.

[0101] In the second switching process (second unfolded state), the hinge cover 230 and the positioning assembly 110 are fixed, and the second body 220 drives the second hinge 130 to rotate relative to the hinge cover 230, so that the hinge cover 230 and the hinge module 100 are partially separated from the second groove G2. In addition, the push rod 161 and the slider 162 of the switching assembly 160 slide in the first direction D1 and the second direction D2 respectively, and finally the second body 220 is suspended on the first body 210.

[0102] To summarize, the hinge module of the present invention has a first hinge and a second hinge. In the first expanded state, the second hinge and the switching assembly drive the positioning assembly to rotate relative to the first hinge, so that the first bracket and the second bracket are expanded to a first angle with each other. Then, in the second expanded state, since the positioning assembly is restricted by the first hinge, the second hinge rotates relative to the positioning assembly and pushes the switching assembly, so that the second bracket continues to rotate and forms a second angle with the first bracket.

[0103] Furthermore, the first body and the second body of the electronic device of the present invention are connected to the corresponding first bracket and the second bracket respectively. When the first body and the second body are switched to the second unfolded state, the second body is suspended above the host, and its position and the center of gravity of the second body are adjusted toward the user, which can slightly shorten the distance between the second body and the user compared to the existing notebook computer. In addition, the forward movement of the center of gravity can reduce the situation where the electronic device is prone to tipping backwards in the unfolded state and can reduce the space occupied by the electronic device after unfolding.

[0104] In addition, the second body is combined with the L-shaped hinge cover. After switching to the second unfolded state, the second body rotates relative to the hinge cover and floats on the first body. Since the second body stores the hinge cover through the second groove, compared with the prior art that connects the screen and the pivot as one, the second body of the electronic device of the present invention has a smaller lower boundary size. After the second body is unfolded, the hinge cover can be shielded to achieve the effect of a narrow frame.
