The hinge module mainly includes a housing, a slider arranged in the housing, a spring arranged at the bottom of the slider, and a cam pivotally connected to the side of the housing and abutting against the slider. When the cam rotates, it drives the slider in contact to slide in the vertical direction, thereby changing the height and compressing the spring to feed back an elastic support force to the cam, so as to stabilize the opening angle of the hinge module and improve the convenience of use.
[0003] In order to make the slider slide more smoothly relative to the housing, usually, lubricating oil is applied between the contact areas of the slider and the housing and the cam. However, this lubrication method may cause the lubricating oil to contaminate the paper in the automatic document feeder. When the hinge module configured in the automatic document feeder is opened or closed, the paper may slide or displace, thereby causing the edge of the paper to contact the lubricating oil remaining on the surface of the cam, resulting in contamination.

Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
[0054] The present application provides a pivot structure module 100, which is suitable for being arranged in an image forming device 200 as shown in the accompanying drawings. Figure 6 The image forming device 200 of an embodiment of the present application is arranged with the pivot structure module 100, and the pivot structure module 100 is arranged in a paper feeding device of the image forming device 200, so as to make the upper cover of the image forming device 200 have a multi-angle support (Free Stop Angle) function. The image forming device 200 can be, for example, a multifunctional office device, a multi-function product / printer / peripheral (MFP), a facsimile machine, a scanner, a copier, or the like, but is not limited thereto.
[0055] Referring to Figure 1 , Figure 2A and Figure 2B , the pivot structure module 100 of the first embodiment of the present application comprises a housing 10, a slider set 20, an isolation assembly 30, a cover 40, a partition plate 50, and a pivot 60.
[0056] The housing 10 comprises a housing body 11, two sliding grooves 12, and two pivot connecting holes 15. The housing body 11 defines a receiving space 13 and an opening 14. The two sliding grooves 12 are respectively formed on opposite sides of the housing body 11 and extend along the vertical direction Y. The two pivot connecting holes 15 are respectively formed on the opposite sides of the housing body 11 and adjacent to the opening 14.
[0057] Referring to Figure 3B , the partition plate 50 is upright in the receiving space 13 and cooperates with the housing body 11 to jointly define a first chamber 131 and a second chamber 132, and the two sliding grooves 12 are formed on the side of the housing body 11 corresponding to the second chamber 132.
[0058] The slider set 20 is disposed in the first chamber 131 of the accommodation space 13, and includes a slider 21 and two first elastic members 22. One end of the two first elastic members 22 is disposed at the bottom of the housing 11. The slider 21 abuts against the other end of the two first elastic members 22, and includes a protrusion 211 formed on a side of the slider 21 adjacent to the opening 14. The two first elastic members 22 are disposed on opposite sides of the first chamber 131 to cooperatively provide elastic support to the slider 21. In the first embodiment, the two first elastic members 22 are compression springs, but are not limited thereto.
[0059] It is to be noted that the number of the first elastic members 22 can be varied according to product requirements, for example, only one first elastic member 22 can be disposed at the center of the bottom of the housing 11, or more than two first elastic members 22 can be disposed, and the foregoing examples and drawings are not limiting.
[0060] Referring again to Figure 1 and Figure 2A , the cover 40 includes a cover plate 41 and a cam 42 connected to the cover plate 41. The cover plate 41 is pivotally connected to the housing 11 adjacent to the side of the slider set 20 by a pivot shaft 60 passing through the two pivot holes 15, and the cam 42 is disposed on a side of the cover plate 41 facing the accommodation space 13 and abutting against the protrusion 211 of the slider 21.
[0061] Referring again to Figure 2B , the isolation assembly 30 is disposed in the second chamber 132 of the accommodation space 13, and includes an isolation plate 31, a second elastic member 32, a first positioning structure 331, a second positioning structure 332, and a plurality of guide columns 34.
[0062] The second positioning structure 332 is formed at the bottom of the housing 11. One end of the second elastic member 32 is disposed at the bottom of the housing 11 and connected to the second positioning structure 332. The first positioning structure 331 is formed on a side of the isolation plate 31 adjacent to the second elastic member 32, and the isolation plate 331 is connected to the other end of the second elastic member 32 by the first positioning structure 331. The side of the isolation plate 31 opposite to the second elastic member 32 abuts against the cover plate 41, and the side edge of the cover plate 41 facing the cam 42 is chamfered to reduce the abrasion between the cover plate 41 and the isolation plate 31.
[0063] In the first embodiment, the isolation plate 31 has two elastic arms 311, two clamping hooks 312, and a plurality of guide ribs 313. The two elastic arms 311 are located at both sides of the isolation plate 31, the two clamping hooks 312 are respectively formed on the two elastic arms 311, and are embedded in the two sliding grooves 12. The guide ribs 313 are formed on the surface of the isolation plate 31 and extend along the vertical direction Y, so as to assist the isolation plate 31 to move along the vertical direction Y.
[0064] The guide columns 34 are located around the second elastic member 32 and are respectively formed on the walls of the partition plate 50 and the housing 11 facing the second cavity 132. The guide columns 34 extend along the vertical direction Y from the bottom of the housing 11, so as to limit the movement of the second elastic member 32 and enable the second elastic member 32 to extend and retract along the vertical direction Y without deviation.
[0065] It is to be noted that in some embodiments of the present application, the number and formation position of the sliding grooves 12 correspond to the clamping hooks 312 of the isolation plate 31, so as to limit the movement of the clamping hooks 312.
[0066] Referring to Figure 3A and Figure 3B , the extension direction of the cover plate 41 and the plane direction X define an included angle θ. When the pivot structure module 100 is in a high-angle open state and the included angle θ is greater than a preset angle, the isolation plate 31 is separated from the cover plate 41 and is not stressed by the cover 40, the cam 42 abuts against the convex portion 211, so as to receive the elastic support force from the first elastic member 22, and the cover 40 remains in an open state. At this time, the isolation plate 31 extends out of the housing 11 from the opening 14 as shown in Figure 3A , and the height thereof along the vertical direction Y is not less than that of the cam 42. Therefore, when the pivot structure module 100 is arranged in the image forming device 200 as shown in Figure 6 and is in a high-angle open state, the isolation plate 31 can prevent paper from directly contacting the cam 42 and being contaminated by ink or lubricating oil.
[0067] Referring to Figure 4A and Figure 4BWhen the cover 40 is closed towards the opening 14, and the included angle θ is less than or equal to the preset angle, the cam 42 abuts against the convex portion 211, and further drives the slider 21 to move towards the bottom of the shell 11, so that the compression amount of the first elastic member 22 is increased, and the elastic support force provided thereby is also increased. At this time, the cover plate 41 abuts against the isolation plate 31, so as to drive the isolation plate 31 to move along the extension direction of the sliding groove 12 and the guide column 34, i.e. the vertical direction Y, towards the bottom of the shell 11, and the second elastic member 32 is compressed by the weight of the cover plate 41 and the isolation plate 31 at the same time, so as to feedback an elastic support force to the isolation plate 31, and the cover plate 41 and the isolation plate 31 are kept abutting against each other during the movement. Therefore, when the pivot structure module 100 is in the low-angle opening state, the isolation plate 31 can block the paper from contacting the cam 42 during the whole use process. The preset angle refers to the range of the included angle θ when the pivot structure module 100 is in the low-angle opening state, and in the first embodiment, the preset angle is 45 degrees, but is not limited thereto.
[0068] Referring to Figure 5A and Figure 5B When the pivot structure module 100 is in the closed state, the included angle θ is 0 degree, at this time, the isolation plate 31 is closer to the bottom of the shell 11, so that the compression amount of the second elastic member 32 is also increased, and the elastic support force fed back to the isolation plate 31 is enhanced. When the pivot structure module 100 is actuated from the closed state to the opening state as shown in Figure 4A or Figure 5A , the isolation plate 31 is lifted upwards along the vertical direction Y by the elastic support force from the second elastic member 32, at this time, the clamping hook 312 embedded in the two sliding grooves 12 can prevent the isolation plate 31 from being separated from the shell 11. In addition, during the opening process, the isolation plate 31 abuts against the cover plate 41, so as to effectively prevent the paper from being contaminated by lubricating oil. In addition, the isolation plate 31 and the second elastic member 32 can also share the stress between the cam 42 and the slider 21 during the operation of the pivot structure module 100, so as to reduce the wear and tear, and make the operation of the pivot structure module 100 more smooth.
[0069] Referring to Figures 7A to 7CIn the second embodiment of the present application, the pivot structure module 100 is provided with at least one third elastic member 70, and both ends of each third elastic member 70 are connected to the cover 40 and the outer side of the shell 11 adjacent to the opening 14. In the second embodiment, the pivot structure module 100 is provided with two third elastic members 70 located on opposite sides of the shell 10, and the third elastic members 70 are compression springs, but the present application is not limited thereto.
[0070] Referring to Figure 7B When the pivot structure module 100 is in the open state, the third elastic member 70 is located on the side of the pivot 60 away from the cam 42, and a torque force opposite to the weight of the cam 42 is generated on the pivot 60, thereby providing a component force of the cam 42 in the vertical direction Y upward, so that the cover 40 is not affected by its own weight or external environment and falls off, and better multi-angle support effect is achieved. Further, since the isolation plate 31 is elastically supported by the second elastic member 32 during the opening of the pivot structure module 100, the third elastic member 70 can cooperate with the second elastic member 32 to provide a force to the cover 40 in the vertical direction Y upward, and further achieve the effect of saving labor.
[0071] Referring to Figure 7C When the pivot structure module 100 is completely closed, the third elastic member 70 is located on the side of the pivot 60 close to the cam 42, and at this time the third elastic member 70 is stretched, thereby providing a component force of the cam 42 in the vertical direction Y downward. Therefore, when the pivot structure module 100 is arranged in the image forming device 200 (as shown in Figure 6 and is in the completely closed state, the third elastic member 70 helps the upper cover of the image forming device 200 to hold the paper downward, thereby helping to improve the quality of image forming.
[0072] Referring to Figure 8A and Figure 8B In the third embodiment of the present application, the isolation plate 31 of the pivot structure module 100 has an elastic arm 311 and a hook 312. The elastic arm 311 is formed on the side of the isolation plate 31 opposite to the cam 42 and located at the central position, and the hook 312 is arranged at the end of the elastic arm 311. The shell 10 has a sliding groove 12 formed on the side of the shell 11 adjacent to the hook 312. When the pivot structure module 100 is actuated, the isolation plate 31 moves along the extension direction of the sliding groove 12, and the hook 312 is embedded in the sliding groove 12, thereby avoiding the isolation plate 31 from being separated from the shell 11.
[0073] It is to be noted that the clamping hook 312 of the isolation plate 31 can have different structures according to the product design requirements, for example, the clamping hook 312 of the isolation plate 31 can also directly extend outward from the surface of the isolation plate 31 to form, without forming the elastic arm 311, or the clamping hook 312 can be formed on one side of the isolation plate 31, and the sliding groove 12 is correspondingly formed on one side of the shell 11, which is not limited to the foregoing examples, as long as the isolation plate 31 can be embedded in the sliding groove 12 through the clamping hook 312.
[0074] In summary, the pivot structure module 100 of the present application is provided with the isolation assembly 30, so that the height of the isolation plate 31 along the vertical direction Y is not lower than the cam 42, whether the pivot structure module 100 is in a high-angle opening state or a medium-low-angle opening state, which can prevent paper from directly touching the lubricating oil on the cam 42 to cause pollution. Further, the isolation plate 31 and the second elastic member 32 can also cooperate to share the stress between the cover 40 and the sliding block 21, which can not only ensure the smooth operation between the sliding block 21 and the cam 42, but also reduce the wear and friction between the cam 42 and the sliding block 21, thereby improving the durability of the pivot structure module 100, so as to achieve the desired effects of the present application.
