Hinge structure and electronic device

Abstract

A hinge structure comprises a fixing base, a rotating support and a magnetic assembly. The rotating support is pivoted to the fixing base. The magnetic assembly is located between the fixed base and the rotating support and comprises a fixed clutch piece, a resistance adjusting piece and a movable clutch piece. The fixed clutch piece is fixed to the rotating support and provided with a first magnet. The resistance adjusting piece is arranged on the fixing base and provided with a plurality of second magnets. The movable clutch piece is arranged between the fixed clutch piece and the resistance adjusting piece and movably connected with the fixed clutch piece. When the rotating support rotates from the lifting-up state to the closing direction to the closing state, the second magnet of the resistance adjusting piece is close to the first magnet of the fixed clutch piece, so that the magnetic repulsive force is increased. Thus, when the rotating support is connected with the display assembly, the speed reduction effect can be achieved in the process of closing the display assembly, and the use safety can be improved.

Description

Technical Field

[0001] The present disclosure relates to a hinge structure and an electronic device having the hinge structure. Background Art

[0002] In order to meet the needs of automated monitoring, LCD keyboard-video-mouse switch (LCD KVM switch) with LCD monitor has been widely used in the industry. Its appearance is similar to that of a laptop computer, but it has the function of switching signal sources.

[0003] Generally speaking, whether it is an LCD KVM switch or a notebook computer, the hinge structure between the display component and the base is designed to be tight-fitting to increase friction to generate resistance, thereby achieving the purpose of opening and closing or fixing the angle of the display component. However, long-term friction will reduce the service life. In addition, the heavier the display component, the higher the torque specification of the hinge structure is required to prevent the display component from falling quickly when it is closed and crushing the user. In this way, the user needs to provide greater force when lifting or closing the display component, which is not only easy to sprain the wrist but also not conducive to the competitiveness of the product. Summary of the invention

[0004] One technical implementation of the present disclosure is a hinge structure, which includes a fixed seat, a rotating bracket and a magnetic assembly. The rotating bracket is pivotally connected to the fixed seat. The magnetic assembly is located between the fixed seat and the rotating bracket, and includes a fixed clutch, a resistance adjustment member, a spring and a movable clutch. The fixed clutch is fixed to the rotating bracket and has a first magnet. The resistance adjustment member is disposed on the fixed seat and has a plurality of second magnets. The spring is connected to the resistance adjustment member and the fixed seat. The movable clutch is disposed between the fixed clutch and the resistance adjustment member and is detachably connected to the fixed clutch. During the period when the rotating bracket rotates from the lifted state to the closed direction to the closed state, the fixed clutch and the movable clutch are coupled so that the second magnet of the resistance adjustment member approaches the first magnet of the fixed clutch, thereby increasing the magnetic repulsion force.

[0005] In some embodiments, the fixed clutch has a first concave-convex structure, and the movable clutch has a second concave-convex structure facing the first concave-convex structure, wherein the first concave-convex structure is coupled with the second concave-convex structure during rotation of the rotating bracket from the flip-up state to the closed state.

[0006] In some embodiments, the magnetic component has a spring connected to the resistance adjustment member and the fixed seat. When the rotating bracket rotates from a closed state to an upward direction to an upward state, the first concave-convex structure presses the second concave-convex structure so that the resistance adjustment member compresses the spring, thereby moving the multiple second magnets away from the first magnet and reducing the magnetic repulsion force.

[0007] In some embodiments, the first concave-convex structure includes a plurality of first protrusions and a plurality of first concave portions, each of the plurality of first protrusions having adjacent arc surfaces and vertical surfaces, and the second concave-convex structure includes a plurality of second protrusions and a plurality of second concave portions, each of the plurality of second protrusions having adjacent arc surfaces and vertical surfaces, and when the rotating bracket rotates from the lifted state to the closed direction to the closed state, the plurality of vertical surfaces of the plurality of second protrusions respectively abut against the plurality of vertical surfaces of the plurality of first protrusions.

[0008] In some embodiments, the movable clutch component has a convex hook facing the resistance adjustment component, the resistance adjustment component has a third concave-convex structure, and the convex hook and the third concave-convex structure define a ratchet structure.

[0009] In some embodiments, the convex hook includes an adjacent inclined portion and a horizontal portion, the horizontal portion has a suspended end, and when the rotating bracket rotates from the closed state to the upward lifting direction to the upward lifting state, the suspended end of the horizontal portion abuts against the convex portion of the third concave-convex structure.

[0010] In some embodiments, the plurality of second magnets are arranged along a semicircle, the plurality of second magnets have a first portion in a range of a central angle of 0 to 70 degrees of the semicircle and a second portion in a range of a central angle of 70 to 120 degrees of the semicircle, the sizes of the plurality of second magnets in the first portion gradually increase from a central angle of 70 to 0 degrees of the semicircle, the sizes of the plurality of second magnets in the second portion are the same, and the density of the plurality of second magnets in the second portion is greater than the density of the plurality of second magnets in the first portion.

[0011] In some embodiments, the hinge structure further includes a rotating shaft and a torsion spring. The rotating shaft passes through the rotating bracket, the magnetic assembly and the fixing seat. The torsion spring is located in the rotating shaft or sleeved on the rotating shaft, and the two ends of the torsion spring are respectively connected to the rotating bracket and the fixing seat, wherein the rotating shaft selectively has two openings for the two ends of the torsion spring to extend out respectively.

[0012] Another technical implementation of the present disclosure is an electronic device, which includes a base, a display assembly and a hinge structure. The display assembly is arranged on the base. The hinge structure connects the base and the display assembly and enables the display assembly to pivot relative to the base, wherein the hinge structure includes a fixed base, a rotating bracket, a fixed clutch, a resistance adjustment member and a movable clutch. The fixed base is arranged on the base. The rotating bracket is pivoted to the fixed base and connected to the display assembly. The fixed clutch is fixed to the rotating bracket and has a first magnet. The resistance adjustment member is arranged on the fixed base and has a plurality of second magnets. The movable clutch is arranged between the fixed clutch and the resistance adjustment member and is detachably connected to the fixed clutch. During the period when the display assembly rotates from the flip-up state to the base to the closed state, the fixed clutch is coupled with the movable clutch, so that the second magnet of the resistance adjustment member approaches the first magnet of the fixed clutch, thereby increasing the magnetic repulsion force.

[0013] In some embodiments, the fixed clutch has a first concave-convex structure, and the movable clutch has a second concave-convex structure facing the first concave-convex structure, wherein the first concave-convex structure is coupled with the second concave-convex structure during rotation of the display assembly from the flip-up state to the closed state.

[0014] In summary, since the magnetic assembly of the hinge structure includes a fixed clutch, a resistance adjustment member, a spring and a movable clutch, and the fixed clutch has a first magnet, and the resistance adjustment member has a plurality of second magnets, during the period when the rotating bracket rotates from the upper flip state to the closed state, the resistance adjustment member can be pushed toward the fixed clutch by the spring, so that the fixed clutch is coupled with the movable clutch, and then the second magnet of the resistance adjustment member is close to the first magnet of the fixed clutch, thereby increasing the magnetic repulsion force and achieving a buffering effect. In this way, when the rotating bracket of the hinge structure is connected to the display assembly of the LCD KVM switch or the display assembly of the notebook computer, a deceleration effect can be obtained during the process of closing the display assembly, which can improve the safety of use. In addition, during the period when the rotating bracket rotates from the closed state to the upper flip direction to the upper flip state, the fixed clutch can press the movable clutch so that the resistance adjustment member compresses the spring, thereby making the second magnet away from the first magnet and reducing the magnetic repulsion force. In this way, when the rotating bracket of the hinge structure is connected to the display assembly of the LCD KVM switch or the display assembly of the notebook computer, a labor-saving effect can be obtained during the process of flipping the display assembly, which is conducive to operation. Resistance is provided by magnetic force, and there are different resistances during the opening and closing process, thereby extending the service life of the hinge structure and facilitating the user experience.

[0068] Figure 1 FIG. 1 is a schematic diagram showing a hinge structure 100 according to an embodiment of the present disclosure being applied to an electronic device 200 . Figure 2 Show Figure 1 A three-dimensional diagram of a hinge structure 100 is shown. Figure 1 and Figure 2 , the hinge structure 100 is located in the electronic device 200 and is configured to connect the base 202 and the display component 204 of the electronic device 200. The display component 204 is disposed on the base 202. The hinge structure 100 connects the base 202 and the display component 204 so that the display component 204 can pivot relative to the base 202. In some embodiments, the electronic device 200 can be a keyboard-video-mouse switch (LCD keyboard-video-mouse switch, LCD KVM switch) or a laptop computer equipped with a liquid crystal display (such as the display component 204). The base 202 may include components such as a keyboard, a processor, a memory, a hard disk, and a connector. The hinge structure 100 includes a fixed base 110, a rotating bracket 120, and a magnetic component 130. The fixed base 110 is disposed on the base 202, and the rotating bracket 120 is connected to the display component 204 and is pivoted to the fixed base 110. The magnetic component 130 is located between the fixed base 110 and the rotating bracket 120. In the following description, the components and operation mechanism of the hinge structure 100 will be described in detail.

[0069] Figure 3 Show Figure 2FIG. 1 is an exploded view of the hinge structure 100. The magnetic assembly 130 includes a fixed clutch 132, a resistance adjustment member 134, a spring 136 and a movable clutch 138. The fixed clutch 132 is fixed to the rotating bracket 120 and has a first magnet 131 and a first concave-convex structure 133. The resistance adjustment member 134 is disposed on the fixed seat 110 and has a plurality of second magnets 135, and the second magnets 135 face the fixed clutch 132. The spring 136 is connected to the resistance adjustment member 134 and the fixed seat 110. The movable clutch 138 is located on a side of the resistance adjustment member 134 that faces away from the spring 136. The movable clutch 138 is disposed between the fixed clutch 132 and the resistance adjustment member 134 and is detachably connected to the fixed clutch 132. The movable clutch 138 has a second concave-convex structure 137 facing the first concave-convex structure 133. In addition, the hinge structure 100 also includes a rotating shaft 140. The rotating shaft 140 passes through the rotating bracket 120 , the magnetic assembly 130 and the fixing base 110 , and is locked to the fixing base 110 by a nut 142 .

[0070] Figure 4 Show Figure 2 A partial enlarged view of the hinge structure 100. Figure 5 Show Figure 4 A three-dimensional diagram of the hinge structure 100 when the rotating bracket 120 rotates in the upward direction D1. Figure 4 and Figure 5 The movable clutch 138 does not rotate in the upward direction D1 of the resistance adjustment member 134, but is only configured to rotate in the closing direction D3 of the resistance adjustment member 134. In other words, the movable clutch 138 is a one-way rotating design on the resistance adjustment member 134 (will be Figure 8 When the first concave-convex structure 133 of the fixed clutch 132 rotates in the upward direction D1 along with the rotating bracket 120, the first concave-convex structure 133 presses the second concave-convex structure 137 of the movable clutch 138 (see Figure 3 ), the movable clutch 138 and the resistance adjusting member 134 move together in the direction D2, and the spring 136 is compressed by the resistance adjusting member 134. When the first concave-convex structure 133 of the fixed clutch 132 rotates along with the rotating bracket 120 in the closing direction D3, the second concave-convex structure 137 of the movable clutch 138 can be coupled with the first concave-convex structure 133 of the fixed clutch 132 due to the elastic force of the spring 136, so that the movable clutch 138 and the resistance adjusting member 134 move together in the direction D4, and the movable clutch 138 rotates along with the fixed clutch 132 and the rotating bracket 120 in the closing direction D3.

[0071] Figure 6 Show Figure 4 A top view of the hinge structure 100 after the rotating bracket 120 rotates in the upward direction D1. Figure 4 and Figure 6 During the period when the rotating bracket 120 rotates from the closed state to the upward flipping direction D1 to the upward flipping state, the movable clutch 138 and the resistance adjustment member 134 are pressed by the first concave-convex structure 133 of the fixed clutch 132 and move in the direction D2, so the second magnet 135 of the resistance adjustment member 134 will be away from the first magnet 131 of the fixed clutch 132, thereby reducing the magnetic repulsive force. In this way, when the rotating bracket 120 of the hinge structure 100 is connected to the display assembly 204 of the electronic device 200, the process of flipping the display assembly 204 will be labor-saving, which is convenient for operation.

[0072] In this embodiment, the first concave-convex structure 133 of the fixed clutch 132 includes a plurality of first protrusions P1 and a plurality of first recesses C1, each of which has an adjacent arc surface S1 and a vertical surface V1. The second concave-convex structure 137 of the movable clutch 138 includes a plurality of second protrusions P2 and a plurality of second recesses C2, each of which has an adjacent arc surface S2 and a vertical surface V2. The vertical surface V1 of the first protrusion P1 and the vertical surface V2 of the second protrusion P2 are parallel to the length direction (e.g., direction D2) of the rotating shaft 140. The design of the arc surfaces S1 and S2 not only makes it easier to save effort when the rotating bracket 120 rotates in the lifting direction D1, but also effectively moves the movable clutch 138 in the direction D2 to compress the spring.

[0073] Figure 7 Show Figure 5 A top view of the hinge structure 100 after the rotating bracket 120 rotates in the closing direction D3. Figure 5 and Figure 7 During the period when the rotating bracket 120 rotates from the upper flip state to the closed direction D3 to the closed state, the second concave-convex structure 137 of the movable clutch 138 is coupled with the first concave-convex structure 133 of the fixed clutch 132, so that the resistance adjustment member 134 is moved in the direction D4 by the elastic force, so that the second magnet 135 of the resistance adjustment member 134 will be close to the first magnet 131 of the fixed clutch 132, thereby increasing the magnetic repulsive force. When the hinge structure 100 is applied to the aforementioned electronic device 200, the period when the rotating bracket 120 rotates from the upper flip state to the closed state is synchronized with the period when the display component 204 rotates from the upper flip state to the base 202 to the closed state, and during this period, the fixed clutch 132 is coupled with the movable clutch 138. In this way, when the rotating bracket 120 of the hinge structure 100 is connected to the display component 204 of the electronic device 200, a deceleration effect can be obtained during the process of closing the display component 204, which can improve the safety of use.

[0074] In addition, when the rotating bracket 120 rotates from the upward state to the closed direction D3 to the closed state, the vertical surface V2 of the second protrusion P2 respectively abuts against the vertical surface V1 of the first protrusion P1. The design of the vertical surfaces V1 and V2 can ensure that the first concave-convex structure 133 and the second concave-convex structure 137 are coupled and not separated when the rotating bracket 120 rotates to the closed direction D3, thereby maintaining sufficient magnetic repulsion between the first magnet 131 and the second magnet 135 to provide a buffering effect.

[0075] Through the above design, the resistance source of the hinge structure 100 can be magnetic force, and there are different resistances during the opening and closing process, thereby extending the service life and facilitating the user experience.

[0076] Figure 8 Show Figure 3 A three-dimensional view of the resistance adjustment member 134 after being combined with the spring 136 but not yet combined with the movable clutch member 138. Fig. 9 Show Figure 8 Another perspective view of the resistance adjustment member 134, the spring 136 and the movable clutch member 138. Figure 8 and Fig. 9 The movable clutch 138 has a convex hook 139 facing the resistance adjustment member 134. The resistance adjustment member 134 has a third concave-convex structure 151. The convex hook 139 of the movable clutch 138 and the third concave-convex structure 151 of the resistance adjustment member 134 define a ratchet structure that can only rotate in one direction.

[0077] Fig.10 Show Fig. 9 A partial cross-sectional diagram of the resistance adjustment member 134 and the movable clutch member 138 after being combined. Fig. 9 and Fig.10 The hook 139 of the movable clutch member 138 includes an adjacent inclined portion 153 and a horizontal portion 154. The horizontal portion 154 has a suspended end. Figure 4 The rotating bracket 120 rotates from the closed state to the upward direction D1. Figure 5 During the upward flipping state, the suspended end of the horizontal portion 154 of the convex hook 139 abuts against the convex portion 152 of the third concave-convex structure 151. Figure 5 The rotating bracket 120 rotates from the lifted state to the closed direction D3. Figure 4 During the closed state, the inclined portion 153 of the convex hook 139 can slide over the plurality of convex portions 152 of the third concave-convex structure 151 to achieve a one-way rotation effect.

[0078] Fig.11 FIG. 1 shows a schematic diagram of the configuration of the second magnets 135a, 135b, and 135c according to an embodiment of the present disclosure. Figure 3 ) can be Fig.11The second magnets 135a, 135b, and 135c are arranged in a semicircle. The second magnets 135a of the first part are in the range of 0 to 70 degrees of the center angle of the semicircle (i.e., region R1), the second magnets 135b of the second part are in the range of 70 to 120 degrees of the center angle of the semicircle (i.e., region R2), and the second magnets 135c of the third part are in the range of 120 to 180 degrees of the center angle of the semicircle (i.e., region R3). In this embodiment, the size of the second magnets 135a of the first part gradually increases from 70 degrees to 0 degrees of the center angle of the semicircle, the size of the second magnets 135b of the second part is the same, and the size of the second magnets 135c of the third part gradually increases from 120 degrees to 180 degrees of the center angle of the semicircle. In addition, the density of the second magnet 135 b in the second portion is greater than the density of the second magnet 135 a in the first portion and the density of the second magnet 135 c in the third portion.

[0079] when Figure 4 The rotating bracket 120 rotates from the closed state to the upward direction D1. Figure 5 During the upward state, the first magnet 131 of the fixed clutch member 132 can pass through the second magnets 135a, 135b, 135c of the resistance adjustment member 134 in sequence along the upward direction D1. Figure 1 After the display assembly 204 is lifted from the original closed state to a suitable viewing position by applying force, the force can be removed, and the rotating bracket 120 is Figure 5 status, and Figure 5 The second concave-convex structure 137 can move in the direction D4 due to the elastic force of the spring 136 and couple with the first concave-convex structure 133, so that the second magnet 135b (such as Fig.11) can provide a magnetic repulsive force to the first magnet 131. In this embodiment, the area R2 where the second magnet 135b is located is an angle suitable for viewing the display screen, and the second magnets 135b with a larger density (i.e., a larger number per unit area) can provide more segments of positioning functions. In addition, the areas R1 and R3 where the second magnets 135a and 135c are respectively located are greatly affected by the gravity in the vertical direction of the display component 204. Therefore, sufficient magnetic repulsive force is provided by the first magnet 131 and the second magnets 135a and 135c with gradually changing sizes to effectively support the weight of the display component 204, such as the small angle in the area R1 to lift up the display component 204 or the large angle in the area R3 to lift up the display component 204. In some embodiments, the first magnet 131 of the fixed clutch member 132 can pass through the second magnets 135b and 135c of the resistance adjustment member 134 in sequence along the closing direction D3, so that sufficient magnetic repulsion can be provided by the first magnet 131 and the second magnet 135a with gradually changing size to effectively slow down the closing speed of the display component 204, for example, allowing the display component 204 to slowly close in the area R1 only by its gravity.

[0080] It should be understood that the connection relationship of the components and the technical effects described above will not be repeated, and will be described first. In the following description, other types of hinge structures will be described.

The torsion spring 160 is located in the rotating shaft 140, and the two ends 162 and 164 of the torsion spring 160 extend from the openings O1 and O2 of the rotating shaft 140 respectively. One end 162 of the torsion spring 160 is connected to the rotating bracket 120, and the other end 164 of the torsion spring 160 is connected to the fixing base 110. In one embodiment, the torsion spring 160 can be connected to the element (for example, a display component) connected to the rotating bracket 120, so when the user operates to flip up the display component, the torsion spring 160 can provide an auxiliary force for flipping upward, thereby saving more effort.

The torsion spring 160a is sleeved on the rotating shaft 140. One end 162 of the torsion spring 160a is connected to the rotating bracket 120, and the other end 164 of the torsion spring 160a is connected to the portion of the fixing base 110a away from the magnetic assembly 130. In one embodiment, the torsion spring 160a can be connected to the element (for example, a display assembly) connected to the rotating bracket 120, so when the user operates to lift up the display assembly, the torsion spring 160a can provide an auxiliary force for lifting it up, thereby saving more effort.
