Description

Technical Field

[0001] This application relates to office equipment, and more specifically, to a pivot structure module and an image forming device. Background Technology

[0002] Currently, most office equipment on the market, such as multifunctional office devices, multi-function products / printers / peripherals (MFPs), fax machines, scanners, and printers, are equipped with an Automatic Document Feeder (ADF). To improve user convenience, ADFs are typically equipped with a hinge module featuring multi-angle support (free stop angle). Such hinge modules usually include a frame, a cam shaft, and a slider mounted on the frame. The cam of the cam shaft abuts against the slider, and a compression spring is located at the bottom of the slider. During the opening and closing of the hinge module, rotating the cam shaft changes the relative height of the slider, causing the compression spring to deform. The compression spring provides elastic support to the slider and cam, supporting the ADF module to stably stop at different opening angles.

[0003] To facilitate user operation, the automatic paper feed module can stably maintain its current angle within a specific opening angle range (e.g., approximately 10° to 70°). This requires a compression spring with a high elastic coefficient. Simultaneously, to ensure smooth sliding of the slider within the frame, the slider's side typically contacts the inner wall of the frame with only a small contact area (e.g., a rib structure), and lubricating grease is applied to the contact area to reduce frictional resistance. However, the frame is often made of plastic and is prone to wear, and the lubricating grease cannot maintain its lubricating effect for an extended period during slider movement, leading to noise and wear at the contact area between the slider and the frame. Particularly during the downward pressing of the automatic paper feed module, the front side of the slider is subjected to a horizontal lateral force, further exacerbating wear and affecting overall performance and lifespan. Therefore, extending the lubrication effect between the frame and the slider is one of the issues that the relevant field seeks to improve. Utility Model Content

[0004] This application provides a pivot structure module suitable for use in office equipment such as multi-functional office equipment, fax machines, scanners, printers, or office machines. During the operation of the pivot structure module, the structural design of two sets of slider components and partitions allows lubricating oil to remain between the slider and the housing for a longer period of time, thereby reducing wear and extending the product's service life.

[0005] In a first aspect, embodiments of this application provide a pivot structure module, comprising: a housing, a first slider component, a second slider component, a partition component, and a cam component.

[0006] The outer shell includes a main shell and a secondary shell. The main shell defines a main chamber and a platform area. The secondary shell is disposed on the side of the main shell and defines a secondary chamber and a through-hole. The platform area is recessed in the side wall of the main chamber and is located between the main chamber and the secondary chamber. The through-hole is used to connect the secondary chamber and the platform area.

[0007] The first slider component is disposed in the main cavity and includes a first slider and at least one first elastic member. One end of the at least one first elastic member is disposed at the bottom of the main housing, and the first slider is disposed at the other end of the at least one first elastic member.

[0008] The second slider component includes a second slider, an extension section, a second elastic member, and a limiting member. The second slider is disposed in the platform area. The extension section extends from the second slider and extends into the secondary chamber through the opening. The second elastic member is sleeved on the extension section and located in the secondary chamber. The limiting member is located in the secondary chamber and is connected to the end of the extension section away from the second slider. The second elastic member abuts against the secondary housing and the limiting member.

[0009] The partition member is disposed in the secondary chamber and includes a partition and at least one third elastic member. One end of the at least one third elastic member is disposed at the bottom of the secondary housing, and the partition is disposed at the other end of the at least one third elastic member and abuts against the limiting member.

[0010] The cam component includes a plate and a cam. The plate is pivotally connected to the side of the main housing away from the secondary housing. The cam is disposed on the side of the plate facing the main chamber and abuts against the first slider.

[0011] The first slider, the second slider, and the platform area together define an oil-containing space. The first slider component and the second slider component move relative to each other due to the vertical displacement of the partition member.

[0012] In some embodiments of this application, the partition and the limiting member each have matching abutting slopes, and the abutting slope of the partition abuts against the abutting slope of the limiting member. When the partition of the partition member is displaced in the vertical direction, the relative movement between the abutting slope of the partition and the abutting slope of the limiting member drives the limiting member to move in the horizontal direction toward the opening, thereby pushing the second slider toward the first slider.

[0013] In some embodiments of this application, the extension direction of the plate body and the horizontal direction together define an included angle. When the cam member is in the closing process and the included angle is less than or equal to a predetermined angle, the cam drives the first slider to move toward the bottom of the main housing, and the partition is pushed by the plate body to move toward the bottom of the secondary housing, thereby driving the second slider to slide toward the first slider, and together with the first slider, adjust the oil holding space.

[0014] In some embodiments of this application, the first slider has at least one oil baffle plate, which extends from the side edge of the first slider toward the platform area and abuts against the inner wall of the main housing. The oil baffle plates are spaced apart from each other along the vertical direction, and the oil-containing space is defined by the oil baffle plates, the second slider, and the platform area.

[0015] In some embodiments of this application, the first slider has a plurality of vertical ribs disposed on the side of the first slider facing the platform area, spaced apart from each other in the horizontal direction and abutting against the inner wall of the main housing, and the oil-containing space is defined by the oil baffle, the plurality of vertical ribs, the second slider and the platform area.

[0016] In some embodiments of this application, the first slider has a first sliding surface structure facing the second slider, the second slider has a second sliding surface structure facing the first slider, and the shape of the second sliding surface structure matches the shape of the first sliding surface structure.

[0017] In some embodiments of this application, the side of the secondary housing is formed with a groove extending along the vertical direction, the partition has a hook, and the hook is limited and fitted into the groove.

[0018] In some embodiments of this application, the extension direction of the plate body defines an angle with the horizontal direction, and the side of the plate body adjacent to the pivot joint forms an abutment surface. When the angle is a preset maximum angle, the abutment surface abuts against a top surface of the main housing adjacent to the pivot joint.

[0019] In some embodiments of this application, the groove and the opening are respectively formed on different sides of the sub-shell.

[0020] Secondly, embodiments of this application provide an image forming device, including the pivot structure module as described above.

[0021] This application has at least the following beneficial effects: The pivot structure module of this application utilizes the structural design between the partition member, the first slider module, and the second slider module. The partition prevents the cam and lubricating grease from contaminating the paper, and during movement, it drives the limiting member, thereby changing the relative position of the first slider and the second slider. This adjusts the distribution range of the oil-containing space, ensuring sufficient lubrication at the stress-bearing points between the first slider and the main housing. Furthermore, the structural design of the first slider and the main housing also confines the lubricating grease within a specific range (i.e., the oil-containing space), preventing it from leaking out over time, thus extending the lubrication effect and improving the product's service life.

Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0062] This application provides a pivot structure module 100, suitable for configuration in, for example, Figure 7 The image forming device 200 shown is illustrated. In one embodiment of this application, the image forming device 200 includes a pivot structure module 100 for providing a free-stop angle function to the top cover of the image forming device 200. The image forming device 200 can be, for example, a multifunction office device, fax machine, scanner, printer, or office machine, and the pivot structure module 100 can be, for example, a paper feed device configured on the image forming device 200, but is not limited thereto.

[0063] See Figure 1 and Figure 2 The pivot structure module 100 of the first embodiment of this application includes: a housing 10, a first slider member 20, a second slider member 30, a partition member 40, a cam member 50, and a pivot 60.

[0064] See also Figure 3A , Figure 3B and Figure 3CThe outer casing 10 includes a main casing 11 and a secondary casing 12. The main casing 11 defines a main chamber 111 and a platform area 112, and has at least one main fixing part 114, which is spaced apart at the bottom of the main casing 11 and located in the main chamber 111. The platform area 112 is recessed in the side wall of the main chamber 111 and located between the main chamber 111 and the secondary chamber 121 of the secondary casing 12. The secondary casing 12 is disposed on the side of the main casing 11 and defines the secondary chamber 121 and a through-hole 122, and has a sliding groove 123 and at least one primary fixing part 124, which is spaced apart in the secondary chamber 121 and is a groove-shaped structure recessed in the bottom of the secondary casing 12. The through-hole 122 is used to connect the secondary chamber 121 and the platform area 112. The groove 123 is formed on the side of the secondary housing 12 and extends along the vertical direction Y. The groove 123 and the through-hole 122 are respectively formed on different sides of the secondary housing 12. In the first embodiment, the secondary housing 12 is given an example of having one groove 123, and the groove 123 and the through-hole 122 are respectively formed on two opposite sides of the secondary housing 12 spaced apart along the second horizontal direction X2. However, in actual implementation, the number and position of the groove 123 may vary according to product requirements and are not limited to the above example.

[0065] See Figure 2 , Figure 3A and Figure 4C The first slider component 20 is disposed in the main chamber 111 and includes a first slider 21 and at least one first elastic element 22. One end of the first elastic element 22 is disposed at the bottom of the main housing 11 and connected to the main fixing part 114, and the first slider 21 is disposed at the other end of the first elastic element 22. In the first embodiment, taking the first slider component 20 having two first elastic elements 22, and the two first elastic elements 22 being compression springs, as an example, they are used to jointly support the first slider 21, so that the first slider 21 remains balanced and does not tilt during operation, but this is not a limitation. The main housing 11 has two main fixing parts 114. The number and arrangement position of the main fixing parts 114 correspond to the first elastic elements 22.

[0066] See Figure 3D , Figure 4B and 4CSpecifically, the first slider 21 has a protrusion 211, at least one oil baffle 212, a plurality of vertical ribs 213, and a first sliding surface structure 214. The protrusion 211 is formed on the side of the first slider 21 opposite to the bottom of the main housing 11. The oil baffle 212 extends from the side edge of the first slider 21 toward the platform area 112, abuts against the inner wall of the main housing 11, and is spaced apart from each other along the vertical direction Y. The vertical ribs 213 are disposed on the side of the first slider 21 facing the platform area 112, and are spaced apart from each other along the first horizontal direction X1 and abut against the inner wall of the main housing 11. The first sliding surface structure 214 is formed on the side of the first slider 21 facing the platform area 112 and faces the second slider 31 of the second slider member 30.

[0067] In the first embodiment, the first slider 21 has two oil baffles 212 and two vertical ribs 213. The two oil baffles 212 are respectively formed on the two side edges of the first slider 21 at intervals along the vertical direction Y. The two vertical ribs 213 are respectively formed on the two side edges of the first slider 21 at intervals along the first horizontal direction X1. The first sliding surface structure 214 is located within the range jointly defined by the vertical ribs 213 and the oil baffles 212, and is composed of a plurality of semi-cylindrical protrusions, which can serve as ribs to improve the mechanical strength of the main slider 21.

[0068] During the operation of the pivot structure module 100, the oil baffle 212 and the vertical rib 213 cooperate with the platform area 112 to limit the lubricating grease located between the first slider 21 and the main housing 11. During the operation of the first slider 21, the oil baffle 212, spaced Y-axis along the vertical direction, pushes the lubricating grease, thereby changing the distribution range of the lubricating grease.

[0069] See also Figure 2 , Figure 3D and Figure 4BThe second slider component 30 includes a second slider 31, an extension 32, a second elastic member 33, a limiting member 34, and a fixing member 35. The second slider 31 is disposed in the platform area 112 and has a second sliding surface structure 311 facing the first slider 21, the shape of which matches the shape of the first sliding surface structure 214. The extension 32 extends from the second slider 31 and extends into the secondary chamber 121 through the opening 122. The limiting member 34 is located in the secondary chamber 121 and connected to the end of the extension 32 away from the second slider 31. The second elastic member 33 is sleeved on the extension 32 and located in the secondary chamber 121, abutting between the secondary housing 12 and the limiting member 34. The fixing member 35 is used to connect the limiting member 34 to the extension 32. In the first embodiment, the fastener 35 is a screw used to fasten the limiting member 34 to one end of the extension 32. When the limiting member 34 moves toward the opening 122, thereby compressing the second elastic member 33, the second elastic member 33 provides an elastic restoring force to the limiting member 34.

[0070] Referring to 4C, in the first embodiment, the second sliding surface structure 311 is composed of a plurality of semi-cylindrical recesses. The first sliding surface structure 214 and the second sliding surface structure 311 are spaced apart by at least one distance and do not contact each other.

[0071] See Figure 4B and Figure 4C In the first embodiment, the first sliding surface structure 214 of the first slider 21, the oil baffle 212, the vertical rib 213, the second slider 31, and the platform area 112 together define an oil-containing space S for accommodating lubricating grease. When the relative positional relationship between the first slider 21 and the second slider 31 changes, the oil-containing space S (i.e., the distribution range of the lubricating grease) changes accordingly, wherein the first sliding surface structure 214 and the second sliding surface structure 311 cooperate to guide the flow direction of the lubricating grease.

[0072] See Figure 2 , Figure 4A and Figure 4BThe partition member 40 is disposed in the secondary chamber 121 and includes a partition 41 and at least one third elastic member 42. One end of the third elastic member 42 is disposed at the bottom of the secondary housing 12 and connected to the secondary fixing part 124. The partition 41 is disposed at the other end of the third elastic member 42 and abuts against the limiting member 34. The partition 41 has an elastic arm 413 and a hook 412. The elastic arm 413 extends from the partition 41, and the hook 412 is formed at the free end of the elastic arm 413. The hook 412 is limited and fitted into the sliding groove 123, so that the partition 41 will not detach from the secondary housing 12 during the movement of the partition 41 along the vertical direction Y. In the first embodiment, the partition member 40 has two third elastic members 42 to jointly support the partition 41, so that the partition 41 is not easily tilted during the movement, but this is not a limitation. The secondary housing 12 has secondary fixing parts 124, the number of which and their arrangement correspond to the third elastic member 42.

[0073] In detail, the contact areas of the partition 41 and the limiting member 34 are respectively formed with matching abutting inclined surfaces 411 and 341, and the abutting inclined surface 411 of the partition 41 abuts against the abutting inclined surface 341 of the limiting member 34. When the partition 41 is displaced along the vertical direction Y, relative movement occurs between the abutting inclined surface 411 of the partition 41 and the abutting inclined surface 341 of the limiting member 34. The partition 41 provides a lateral force to the limiting member 34 through its abutting inclined surface 411, causing the first slider member 20 and the second slider member 30 to move relative to each other. More specifically, the abutting slope 341 of the limiting member 34 is inclined toward the side opposite to the main housing 11. Therefore, when the partition 41 slides along the abutting slope 341 of the limiting member 34 and moves toward the bottom of the secondary housing 12, a lateral force is simultaneously generated in the limiting member 34 toward the main housing 11, thereby driving the limiting member 34 to move toward the opening 122 along the second horizontal direction X2, thereby pushing the second slider 31 toward the first slider 21.

[0074] See also Figure 2 , Figure 4A and Figure 4B The cam member 50 includes a plate 51 and a cam 52. The plate 51 is pivotally connected to the side of the main housing 11 away from the secondary housing 12 via the pivot 60, and the side of the plate 51 adjacent to the pivot point forms an abutment surface 511. The cam 52 is disposed on the side of the plate 51 facing the main chamber 111 and abuts against the protrusion 211 of the first slider 21.

[0075] The extension direction of the plate 51 forms an angle θ with the second horizontal direction X2, and the angle θ is the range within which the pivot structure module 100 can maintain multi-angle support function. The first horizontal direction X1 and the second horizontal direction X2 are coplanar and orthogonal to each other.

[0076] See Figure 4A , Figure 4B and Figure 4C , Figure 4B and Figure 4C Corresponding to Figure 1 The cross-sectional structures of the BB and CC facets are shown. When the pivot structure module 100 is in operation, when the included angle θ is a preset maximum angle (e.g., 70 degrees), the pivot structure module 100 is at its maximum holding angle. The partition 41 is not subjected to force by the cam member 50 and extends beyond the sub-housing 12. The height of the partition 41 along the vertical direction Y is higher than that of the cam 52. Therefore, when the pivot structure module 100 is configured in an image forming device 200 (e.g., ...), Figure 7 When the pivot structure module 100 is at its maximum holding angle (as shown), the partition 41 prevents the paper from directly contacting the cam 52 and the lubricating grease located in the oil-containing space S, effectively preventing the paper from being contaminated by ink or lubricating grease. Furthermore, when the pivot structure module 100 is at its maximum holding angle, the oil-containing space S (as shown)... Figure 4B and Figure 4C The dashed area shown) 12 is relatively distributed on the side of the second slider 31 away from the bottom of the main housing 11.

[0077] Simultaneously, the cam 52 abuts against the protrusion 211 of the first slider 21, providing the first slider 21 with a downward component force along the vertical direction Y. The first elastic member 22, after compression, provides an elastic support force to the first slider 21 and the cam 52, causing the cam member 50 to stably remain at the preset maximum angle. At this time, the abutting surface 511 of the plate 51 abuts against a top surface 113 of the main housing 11 adjacent to the pivot point, which helps to limit the opening angle of the plate 51.

[0078] See Figure 5A and Figure 5B , Figure 5B For corresponding Figure 1The cross-sectional structure of the BB cut line is shown. During the closing process of the pivot structure module 100, the included angle θ gradually decreases. When the included angle θ is less than or equal to a preset angle (e.g., 45 degrees), the side of the plate 51 away from the pivot point abuts against the partition 41. The partition 41 is subjected to force from the plate 51 and moves towards the bottom of the secondary housing 12. The third elastic member 42, after compression, feeds back an elastic support force to the partition 41, causing the partition 41 and the plate 51 of the cam member 50 to abut against each other, effectively preventing the paper from being contaminated by ink or lubricating grease. Furthermore, during the movement of the partition 41 towards the bottom of the secondary housing 12, it also provides the lateral force to the limiting member 34, thereby driving the second slider 31 to move towards the first slider 21 via the limiting member 34. Simultaneously, the first slider 21, subjected to force by the cam 52, moves towards the bottom of the main housing 11, and the distribution range of the oil-containing space S also changes with the relative positional relationship between the first slider 21 and the second slider 31. When the first slider 21 moves, the oil baffle 212, disposed on the first slider 21 and located on one side opposite to the direction of movement, pushes the lubricating grease to flow in the direction of movement of the first slider 21.

[0079] Specifically, during the closing process of the pivot structure module 100, the spacing distance between the first slider 21 and the second slider 31 along the second horizontal direction X2 (e.g., Figure 4C As shown, the first slider 21 gradually shortens relative to the second slider 31 towards the bottom of the main housing 11. The oil baffle 212, located on the first slider 21 and away from the bottom of the main housing 11, pushes the lubricating grease towards the bottom of the main housing 11, causing at least a portion of the lubricating grease to flow from the center outwards along the guidance of the first sliding surface structure 214 and the second sliding surface structure 311. Therefore, although the compression of the first elastic element 22 increases, thereby strengthening the elastic support force it provides to the first slider 21 and exacerbating the friction and wear between the first slider 21 and the main housing 11, the lubricating grease also flows to the stress-bearing areas between the first slider 21 and the main housing 11, maintaining good lubrication.

[0080] During the opening process of the pivot structure module 100 from its closed state, the third elastic member 42 provides the elastic support force to the partition 41, causing the partition 41 to abut against the plate 51 of the cam member 50, thereby preventing the paper from being contaminated by ink or lubricating grease due to slippage during the opening process.

[0081] See Figure 6A , Figure 6B and Figure 6C , Figure 6B and Figure 6C Corresponding to Figure 1 The cross-sectional structure shown is the BB and CC section lines. When the pivot structure module 100 is fully closed, the plate 51 drives the partition 41 to press down and pushes the limiting member 34 towards the opening 122 until it abuts against the periphery of the opening 122, thereby driving the second slider 31 to move to the closest distance to the first slider 21, and the first slider 21 moves towards the bottom of the main housing 11 until one of the oil baffles 212 presses against the second slider 31, and the oil-containing space S (such as...) Figure 6B The area indicated by the dashed line is distributed on the side of the second slider 31 adjacent to the bottom of the main housing 11. At this time, the compression of the first elastic member 22 reaches its maximum, and the friction and wear on the contact area between the first slider 21 and the main housing 11 are further intensified. The lubricating grease flows to both sides along the first sliding surface structure 214 and the second sliding surface structure 311 to further increase the lubrication effect of the contact area between the first slider 21 and the main housing 11. A gap is maintained between the first slider 21 and the second slider 31, preventing them from contacting each other, so that the lubricating grease can be fully distributed between the first slider 21 and the main housing 11, and between the first slider 21 and the second slider 31 to achieve a lubrication effect. Furthermore, the vertical rib 213 and the oil baffle 212 can confine the lubricating grease within the oil-containing space S, preventing the lubricating grease from being lost during the movement of the first slider 21, thus preventing the lubrication effect from deteriorating over time.

[0082] See Figure 8A In the second embodiment of the pivot structure module 100 of this application, the first slider 21 is provided with only one oil baffle 212, and the oil baffle 212 is provided on the side edge of the first slider 21 adjacent to the protrusion 211. The first sliding surface structure 214 is a triangular platform structure, and the triangular platform structure has two platform sides extending from the center to the outside. The second sliding surface structure 311 is a flat surface structure.

[0083] See Figure 8B and Figure 8C , Figure 8B and Figure 8C For corresponding Figure 1The cross-sectional view along the CC section illustrates the structural states of the pivot structure module 100 when it is at its maximum holding angle and when it is fully closed. In the second embodiment, when the pivot structure module 100 is at its maximum holding angle, the included angle θ is a preset maximum angle (e.g., ...). Figure 4A As shown in the figure, the distribution range of the oil-containing space is as follows: Figure 8B As shown, the oil space S is uniformly distributed along the first horizontal direction X1; when the pivot structure module 100 is fully closed, the distribution range of the oil-containing space S is as follows: Figure 8C As shown, at least a portion of the lubricating grease flows to both sides via the first sliding surface structure 214 and the second sliding surface structure 311.

[0084] See Figure 9A In the third embodiment of the pivot structure module 100 of this application, the first sliding surface structure 214 is a prismatic structure composed of two inclined surfaces, and the second sliding surface structure 311 is a groove structure composed of two inclined surfaces, which can be matched with the first sliding surface structure 214.

[0085] See Figure 9B and Figure 9C , Figure 9B and Figure 9C For corresponding Figure 1 The cross-sectional view of the CC section shown illustrates the structural states of the pivot structure module 100 at its maximum holding angle and when it is fully closed. In the third embodiment, the distribution range of the oil-containing space S is as follows: Figure 9B As shown, the oil space S is uniformly distributed along the first horizontal direction X1; when the pivot structure module 100 is fully closed, the distribution range of the oil-containing space S is as follows: Figure 9C As shown, at least a portion of the lubricating grease flows to both sides via the first sliding surface structure 214 and the second sliding surface structure 311.

[0086] It should be noted that the structural design of the first sliding surface structure 214 and the second sliding surface structure 311 of the pivot structure module 100 of this application may vary depending on actual needs and is not limited to the examples mentioned above.

[0087] In summary, the pivot structure module 100 of this application utilizes the structural design between the partition member 40, the first slider member 20, and the second slider member 30. This design allows the partition 41 to not only prevent the cam 52 and lubricating grease from contaminating the paper, but also to further move the limiting member 34 during movement. This changes the relative positional relationship between the first slider 21 and the second slider 31, thereby adjusting the distribution range of the oil-containing space S. This ensures sufficient lubrication at the stress-bearing points between the first slider 21 and the main housing 11. Furthermore, the structural design of the first slider 21 and the main housing 11 confines the lubricating grease within a specific area, preventing it from leaking out over time, thus extending the lubrication duration and improving the product's lifespan. Therefore, it effectively achieves the desired effect.
