Technical Field
[0001] This application provides a support device, and more particularly a support device that can accommodate excessive clearance caused by manufacturing tolerances. Background Technology
[0002] CN206409839U discloses a height-adjustable bracket, which includes a base, a column, a sliding module, and a spring module. The column is mounted on the base and has a housing, an internal space, and a base. The internal space is defined by the housing and includes a central area and two sliding groove areas located on both sides of the central area. The housing forms two reinforcing blocks located on both sides of the internal space and adjacent to the sliding groove areas. The sliding module is disposed in the internal space and includes at least one self-lubricating block, which is slidably disposed in the corresponding two sliding groove areas.
[0003] The housing is pre-formed with grooves using an aluminum alloy molding process, and reinforcing blocks must be added to increase its mechanical strength. Furthermore, this liftable support can cause a height difference between the left and right sides of the machine when faced with excessive clearances due to manufacturing tolerances. Utility Model Content
[0004] This application provides a support device for supporting a display on a working surface. The support device includes: a base disposed on the working surface; a column disposed on the base substantially along a gravity direction, and comprising a front shell plate, two elongated openings, two fixing plates, and two sliding spaces. The elongated openings are spaced apart from each other on the front shell plate and extend substantially along the gravity direction. The fixing plates are respectively fixed to the front shell plate and adjacent to the elongated openings, and respectively define the sliding spaces relative to the front shell plate. The front shell plate has two stepped portions; a sliding module capable of moving up and down relative to the column along the gravity direction, and comprising a trolley plate and fixed to... The trolley plate has two self-lubricating blocks, which are spaced apart from the stepped portion in a horizontal direction substantially perpendicular to the direction of gravity. The self-lubricating blocks are slidably disposed in the sliding space and limited by the front shell plate and the fixed plate. Each block has at least one arch bridge elastomer, which is sandwiched between the trolley plate and the stepped portion and is used to match the gap between the trolley plate and the stepped portion. An elastic module connects the front shell plate and the sliding module and is used to constantly provide an elastic force. A support member is used to support the display, which passes through the elongated opening and is fixed to the trolley plate.
[0005] As described above, the arch bridge elastomer has a solid volume and a spatial volume. By the relative compression of the trolley plate and the stepped portion, the arch bridge elastomer undergoes different degrees of deformation, changing the spatial volume so that the solid volume and the spatial volume can respectively match the gap.
[0006] As described above, when the gap between the trolley plate and the stepped portion is small, the arch bridge elastomer is compressed, resulting in a large degree of deformation and a relatively small spatial volume. When the gap between the trolley plate and the stepped portion is large, the arch bridge elastomer is compressed, resulting in a smaller degree of deformation and a relatively large spatial volume.
[0007] As described above, each of the self-lubricating blocks also has a body and at least one through hole, the through hole being disposed in the body of the block, and the arch bridge elastic body being connected to the body of the block along the direction of gravity and corresponding to the through hole.
[0008] As described above, the supporting device has two bent sections and one abutting section. The bent sections are respectively located on the main body and away from the trolley plate. The two ends of the abutting section are respectively connected to the bent sections and abut against the trolley plate.
[0009] As described above, each of the self-lubricating blocks also has a plurality of grooves, which are recessed into the block body and face the stepped portion.
[0010] As described above, the front shell plate also has a central plate, the stepped portion extends outward from the central plate and has an inclined surface, the inclined surface and the central plate have an obtuse angle, the block body has a contact surface, the inclined surface and the contact surface match each other.
[0011] As with the aforementioned support device, the obtuse angle ranges from 92 degrees to 100 degrees.
[0012] As described above, the trolley plate has a body, two wing plates and two extension plates. The wing plates extend outward from opposite sides of the body and correspond to the elongated opening, and are fixed to the bearing member. The extension plates extend outward from the wing plates and are respectively disposed in the sliding space. The self-lubricating blocks are respectively sleeved on the extension plates.
[0013] As described above, the fixed plate has a fixed section, a bent section and a limiting section. The fixed section is fixed to the front shell plate. The two ends of the bent section are respectively connected to the fixed section and the limiting section. The limiting section is spaced apart from the front shell plate and surrounds the front shell plate to define the sliding space.
[0014] As described above, the fixed section, the bending section, and the limiting section together have an S-shaped cross-section.
[0015] As described above, the self-lubricating blocks each have a blind groove for the insertion of the extension plate.
[0016] As described above, the self-lubricating block is made of polyoxymethylene (POM).
[0017] In summary, the support device of this application defines a sliding space around the central plate, the stepped portion, and the fixed plate. This sliding space allows the sliding module to slide within it without the need for a slide rail. Furthermore, the self-lubricating block features an arched elastomer design, which reduces excessive clearance between the extension plate and the stepped portion due to manufacturing tolerances, thus eliminating the issue of left-right height difference in the entire machine. Moreover, the front shell plate in the support device of this application is directly demolded, effectively reducing costs and increasing production capacity. Attached Figure Description

[0050] Please see Figure 1 and Figure 2 The support device 1000 of this application is used to support a display 2000 on a working surface 3000. The support device 1000 includes a base 1, a column 2, a sliding module 3, a spring module 4, and a bearing member 5. The base 1 is disposed on the working surface 3000, the column 2 is disposed on the base 1, the sliding module 3 is disposed on the column 2, the spring module 4 is disposed inside the column 2 and connected to the sliding module 3, and the bearing member 5 is disposed on the sliding module 3.
[0051] The base 1 is generally a square plate, which can be stably placed directly on the work surface 3000 (e.g., a tabletop). The column 2 is generally a flat rectangular body, which extends substantially along the direction of gravity G and is set on the base 1 perpendicular to the work surface 3000, but is not limited to this, and can also be set on the base 1 at a slight inclination to the work surface 3000.
[0052] Please refer to the following: Figure 4 and Figure 5 The column 2 includes a front shell plate 21, a rear shell plate 22, two elongated openings 23, two fixed plates 24, and two sliding spaces 25, wherein... Figure 5 The rear shell plate 22 and the fixing plate 24 are omitted from the drawing. The front shell plate 21 has a central plate 211, two stepped portions 212, and a seat block 213. The central plate 211 is generally rectangular. The stepped portions 212 are formed on the central plate 211 and are respectively adjacent to the opposite left and right sides of the central plate 211, and each has an inclined surface 2121. The inclined surfaces 2121 are corresponding to each other and have an obtuse angle θ with the central plate 211. The seat block 213 is formed by bending outward from the central plate 211 and is adjacent to the top edge of the central plate 211. The rear shell plate 22 is generally rectangular and has a triangular cross section, and can be combined with the front shell plate 21. The elongated openings 23 are formed at intervals on the central plate 211 of the front shell plate 21, and generally extend along the direction of gravity G, and are located between the stepped portions 212. The fixing plate 24 has a fixing section 241, a bending section 242, and a limiting section 243. The fixing section 241 is fixed (via screws) to the stepped portion 212 of the front shell plate 21. One end of the bending section 242 is connected to the fixing section 241, and the limiting section 243 is connected to the other end of the bending section 242, so that the fixing section 241, the bending section 242, and the limiting section 243 together have an S-shaped cross-section. The limiting section 243 is spaced apart from the central plate 211 of the front shell plate 21, and together with the central plate 211 and the stepped portion 212, it surrounds and defines the sliding space 25.
[0053] In this embodiment, the height of the stepped portion 212 on the central plate 211 and the degree to which the bent section 242 bends away from the central plate 211 determine the size of the gap (i.e., the sliding space 25) between the limiting section 243 and the central plate 211. Furthermore, the stepped portion 212 is omitted from the front shell plate 21, and the gap between the limiting section 243 and the central plate 211 is determined solely by the bent section 242, and vice versa.
[0054] In this embodiment, the obtuse angle θ ranges from 92 degrees to 100 degrees, preferably from 93 degrees to 95 degrees. The obtuse angle θ is generated by direct demolding of the central plate 211 and the stepped portion 212 (the demolding angle is, for example, about 5 degrees), which reduces the need for NC post-processing of the sliding space 25.
[0055] In this embodiment, the front shell plate 21 and the rear shell plate 22 are made of plastic, while the fixing plate 24 is made of metal.
[0056] Please see Figure 3 and Figure 6 The sliding module 3 can move up and down relative to the column 2 along the direction of gravity G, and includes a trolley plate 31, two self-lubricating blocks 32, and a friction block 33. The trolley plate 31 has a body 311, two wing plates 312, two extension plates 313, and a ring bar 314. The body 311 is a U-shaped plate. The wing plates 312 extend outward from opposite sides of the body 311 and correspond to the elongated opening 23. The extension plates 313 extend outward from the wing plates 312 and are respectively disposed in the sliding space 25, and form a gap D at intervals relative to the stepped portion 212 along the horizontal direction H. The ring bar 314 is also a U-shaped plate and is fixed to the back of the body 311.
[0057] The self-lubricating blocks 32 are respectively sleeved on the edges of the extension plate 313 and slidably disposed in the sliding space 25, and are limited by the limiting section 243 of the central plate 211, the stepped portion 212, and the fixed plate 24. Each self-lubricating block 32 has a body 321, two through holes 322, two arched bridge elastic bodies 323, multiple grooves 324, and a blind groove 325. The block body 321 has a contact surface 3211 facing the inclined surface 2121 and matching the inclined surface 2121, that is, the contact surface 3211 and the central plate 211 are not perpendicular to each other. The through holes 322 are spaced apart from each other in the block body 321.
[0058] The arch bridge elastic body 323 is connected to the block body 321 along the gravity direction G and corresponds to the through hole 322, and each has a solid volume 3231 and a spatial volume 3232. The solid volume 3231 is composed of two bent sections 32311 and an abutting section 32312. The bent sections 32311 are respectively located on the block body 321 and away from the extension plate 313, and abut against the stepped portion 212. The two ends of the abutting section 32312 are respectively connected to the bent sections 32311 and abut against the extension plate 313, and are away from the stepped portion 212. The space between the bent sections 32311 and the extension plate 313 and the space between the abutting section 32312 and the stepped portion 212 constitute the spatial volume 3232. When the gap D between the extension plate 313 and the stepped portion 212 of the trolley plate 31 changes, the trolley plate 31 and the stepped portion 212 exert relative pressure on the arch bridge elastic body 323, causing the arch bridge elastic body 323 to undergo different degrees of deformation, thereby changing the spatial volume 3232. When the gap D between the extension plate 313 and the stepped portion 212 is small, the arch bridge elastomer 323 experiences greater compression and deformation. The abutment section 32312 is relatively close to the stepped portion 212, and the bending section 32311 is relatively close to the extension plate 313, resulting in a relatively small spatial volume 3232. Conversely, when the gap D between the extension plate 313 and the stepped portion 212 is large, the arch bridge elastomer 323 experiences less compression and deformation. The abutment section 32312 is relatively far from the stepped portion 212, and the bending section 32311 is relatively far from the extension plate 313, resulting in a relatively large spatial volume 3232. The arch bridge elastomer 323 can generate different degrees of deformation, allowing the solid volume 3231 and the spatial volume 3232 to respectively match the different gaps D between the extension plate 313 and the stepped portion 212.
[0059] The grooves 324 are recessed at intervals into the contact surface 3211 of the block body 321 and face the stepped portion 212. The blind groove 325 is defined by the block body 321 and connects to the through hole 322, and is correspondingly used for the insertion of the extension plate 313. The friction block 33 has two latching pieces 331, which latch onto the front side of the body 311, so that the friction block 33 is located between the body 311 and the central plate 211 of the front shell plate 21. When the sliding module 3 moves up and down relative to the column 2 in the direction of gravity G, the self-lubricating block 32 rubs against the central plate 211, the stepped portion 212 and the fixed plate 24, and the friction block 33 rubs against the central plate 211. In this embodiment, the self-lubricating block 32 and the friction block 33 are made of polyoxymethylene (POM) material.
[0060] The elastic module 4 includes a base 41 and two constant-force springs 42. The base 41 is fixed (via screws) to the seat block 213. The constant-force springs 42 are used to provide a constant elastic force and each has a connected cylindrical portion 421 and a movable end 422. The cylindrical portion 421 is housed in the base 41. The movable ends 422 are respectively fixed to opposite sides of the annular strip 314 of the trolley plate 31.
[0061] The support member 5 includes a support plate 51 and a protruding neck 52. The support plate 51 is used to support the display 2000. The protruding neck 52 has a neck body 521 and two blocks 522. One end of the neck body 521 is connected to the back of the support plate 51, and the blocks 522 are connected to the other end of the neck body 521 at intervals, and are respectively passed through the elongated opening 23 and fixed to the wing plate 312 of the trolley plate 31 (via screws), thereby clamping the central plate 211 between the support plate 51 and the trolley plate 31.
[0062] The support device 1000 of this application allows the sliding module 3, the carrier 5, and the display 2000 to move up and down relative to the column 2 along the direction of gravity G by applying an external force. The constant force spring 42 constantly provides an elastic force opposite to the direction of gravity G. When the external force is removed, the weight of the display 2000, the elastic force provided by the elastic module 4, and the friction force generated by the self-lubricating block 32 and the friction block 33 will achieve torque balance, allowing the display 2000 to stop at any position. Furthermore, since the contact surface 3211 and the inclined surface 2121 are designed to be parallel to each other, when the sliding module 3 slides relative to the sliding space 25, the contact surface 3211 and the inclined surface 2121 have a limiting function, and the groove 324 can be filled with lubricating oil to reduce the probability of jamming.
[0063] In summary, the support device of this application defines a sliding space around the central plate, the stepped portion, and the fixed plate. This sliding space allows the sliding module to slide within it without the need for a slide rail. Furthermore, the self-lubricating block features an arched elastomer design, which reduces excessive clearance between the extension plate and the stepped portion due to manufacturing tolerances, thus eliminating the issue of left-right height difference in the entire machine. Moreover, the front shell plate in the support device of this application is directly demolded, effectively reducing costs and increasing production capacity.
