Description

Technical Field

[0001] The present application provides a supporting device, in particular a supporting device that can prevent a corner of a display from being impacted. Background Art

[0002] Existing support devices often provide a conversion mechanism that can rotate the display vertically or horizontally, so that users can rotate the display according to their needs. However, when the display is changed from the horizontal direction to the vertical direction, in order to prevent the corner of the display from hitting the desktop, the height of the vertical column of the support device must be sufficient, so the volume of the support device will be larger, which undoubtedly increases the cost and does not conform to the current popular trend of lightweight and miniaturization. Utility Model Content

[0003] The present application provides a support device for carrying a display on a work surface, the support device comprising: a support frame, arranged on the work surface, and comprising a column and an opening, the column substantially extending along a gravity direction, the opening formed on the column; a convex neck, arranged on the column and partially extending from the opening parallel to a first axis; a bearing plate unit for carrying the display, the display can be substantially self-rotated and transformed between a first angle range and a second angle range with the first axis as the center through the bearing plate unit, the second angle range is larger than the first angle range, the bearing plate unit The unit can be tilted between a first position and a second position relative to the convex neck along a second axis perpendicular to the first axis, and includes at least one limiting hole; and a pivot control unit is accommodated in the carrier plate unit and includes a pivot member and an elastic member; wherein, when the carrier plate unit is in the first position, the pivot member is accommodated in the limiting hole to limit the display to be able to rotate and transform only within the first angle range, and when the carrier plate unit is in the second position, the convex neck contacts the pivot member, and the pivot member disengages from the limiting hole, whereby the carrier plate unit can be rotated and transformed within the second angle range.

[0004] As in the aforementioned supporting device, the elastic member constantly provides an elastic force, which tends to make one end of the pivot member abut against the supporting plate unit and be accommodated in the limiting hole when in the first position. When the supporting plate unit tilts from the first position to the second position, the convex neck pushes the pivot member and compresses the elastic member, so that the pivot member moves away from the limiting hole. When the supporting plate unit tilts from the second position to the first position, the convex neck moves away from the pivot member, and the elastic member rebounds, so that the pivot member is accommodated in the limiting hole.

[0005] As in the aforementioned supporting device, the pivot member has a main body, a first wing block and a second wing block, the first wing block and the second wing block are formed by extending outward from opposite sides of the main body, one end of the elastic member abuts the supporting plate unit, and the other end abuts the second wing block.

[0006] As in the aforementioned supporting device, when in the first position, the first wing block is accommodated in the limiting hole, and the second wing block is away from the convex neck; when in the second position, the first wing block is away from the limiting hole, and the second wing block abuts against the convex neck.

[0007] As in the aforementioned supporting device, each of the limiting holes has a first end and a second end opposite to each other. In the first position, the first wing block is limited by the first end or the second end so that the first angle range is ±4 degrees.

[0008] As in the aforementioned supporting device, when the supporting plate unit is in the first position, the inclination angle of the supporting plate unit relative to the protruding neck is between -6 degrees and 18 degrees, and when the supporting plate unit is in the second position, the inclination angle of the supporting plate unit relative to the protruding neck is between 19 degrees and 22 degrees.

[0009] As in the aforementioned supporting device, the elastic member is a torsion spring.

[0010] As in the aforementioned supporting device, the protruding neck includes a neck body, two rods and a protrusion, wherein the rods extend outward from opposite sides of the neck body along the second axis, and the protrusion extends outward from the neck body along a third axis perpendicular to the first axis and the second axis, and pushes the pivot member when the supporting plate unit tilts from the first position to the second position.

[0011] As in the aforementioned supporting device, it also includes a tilting module, which is sleeved on the rod and connected to the supporting plate unit. When the supporting plate unit is tilted relative to the protruding neck, the tilting module generates friction, whereby the supporting plate unit can stop at any position between the first position and the second position.

[0012] As in the aforementioned supporting device, the supporting plate unit also includes a front plate, a main plate, a rear plate and a accommodating space. The accommodating space is defined by the front plate, the main plate and the rear plate. The pivot control unit is fixedly connected to the front plate so that the pivot member is located in the accommodating space. The limiting hole is formed on the main plate and connected to the accommodating space.

[0013] As in the aforementioned supporting device, the supporting plate unit also includes a stop block and two stop plates. The stop block is fixedly connected to the main board, and the stop plates are formed by extending outward from the rear plate relative to each other. When the main board rotates relative to the rear plate, the stop block is limited by the stop plate so that the second angle range is ±90 degrees.

[0014] As in the aforementioned supporting device, the number of the limiting holes is multiple, and the limiting holes are formed on the main board at intervals of 90 degrees from each other, and respectively correspond to the positions of the second angle of -90, 0, and +90 degrees.

[0015] As in the aforementioned supporting device, the pivot control unit further comprises a seat and an axle, the seat is fixed to the front plate, the axle is pivotally connected to the seat and passes through the pivot member so that the pivot member can rotate relative to the seat, and the elastic member is sleeved on the axle.

[0016] In summary, the support device of the present application is designed with a pivot control unit so that the support plate unit can have different self-rotation angle ranges at different inclination angles. At a specific inclination angle, the bottom edge of the display will be raised so that the display can be swung vertically or horizontally, thereby preventing the corner of the display from hitting the desktop during the transition between vertical and horizontal swings. The pivot control unit in the support device of the present application does not need to occupy a large space, thus avoiding the disadvantage of the prior art that the support frame must be enlarged, and the overall cost is low, which conforms to the trend of lightweight and miniaturization.

The opening 13 substantially extends along the gravity direction G and is formed on the side of the column 12.

[0056] Please also see Figure 4 The convex neck 2 comprises a neck body 21, two rods 22 and a projection 23. The neck body 21 is roughly rectangular, disposed on the column 12 and partially extending outward from the opening 13 in a direction parallel to the first axis X1, and one end of the neck body 21 is fixed to a sliding member (such as a pulley, not shown) in the column 12, whereby the neck body 21 can substantially reciprocate relative to the column 12 along the gravity direction G. The rods 22 are respectively extended outward from opposite sides of the neck body 21 along the second axis X2, and respectively have an extension section 221 and a threaded section 222, the extension section 221 is connected to the neck body 21 and has a non-circular cross section, and the threaded section 222 is connected to the end of the extension section 221.

[0058] See also Figure 5 and Figure 6The pivot control unit 4 is accommodated in the carrier plate unit 5 and includes a seat body 41, an axle rod 42, a pivot member 43, an elastic member 44 and two position-limiting fasteners 45. The seat body 41 has a bottom plate 411, two wing plates 412, two axle holes 413 and two tenons 414. The bottom plate 411 is generally a square body, and the wing plates 412 are respectively extended outwardly from two opposite sides of the bottom plate 411, thereby forming a U-shape as a whole. The axle holes 413 are respectively formed through the wing plates 412. The tenons 414 are respectively extended outwardly from one side of the wing plates 412 and fixedly connected to the carrier plate unit 5. The axle rod 42 passes through the axle hole 413. The pivot member 43 has a body 431, a through hole 432, a first wing block 433 and a second wing block 434. The body 431 is roughly cylindrical, and a through hole 432 is formed through the body 431. The shaft 42 is arranged in the through hole 432 in a direction parallel to the second axis X2, so that the body 431 can rotate relative to the seat 41 with the shaft 42 as the axis. The first wing block 433 extends outward from the top side of the body 431 and is roughly L-shaped. The second wing block 434 has a bending portion 4341 and two abutting portions 4342. The bending portion 4341 extends outward from the bottom side of the body 431 and is roughly L-shaped. The abutting portions 4342 extend outward from the opposite sides of the bending portion 4341, so that the whole is roughly T-shaped. The elastic member 44 is specifically a torsion spring, and has two winding portions 441, two end portions 442 and a connecting section 443. The winding parts 441 are sleeved on the shaft 42 at intervals and are located on opposite sides of the body 431. The end parts 442 are respectively connected to one end of the winding parts 441 and abut against the carrier plate unit 5. The connecting section 443 is connected to the other end of the winding parts 441 and abuts against the bending part 4341, and is limited by the abutting part 4342. The limiting fasteners 45 are clamped on the shaft 42 at intervals and are respectively located between the winding parts 441 and the body 431 to prevent the winding parts 441 from rubbing against the body 431.

[0059] Please also see Figure 2 , Figure 3 and Figure 7 The carrier plate unit 5 includes a front plate 51, a main plate 52, a rear plate 53, a receiving space 54, three limiting holes 55, a stop block 56, two stop plates 57 and two friction rings 58 ( Figure 7The front plate 51 and a friction ring 58 are omitted. The front plate 51 is generally a circular plate, which is arranged on the front side of the main plate 52 and can be locked to the rear plate 53, and the two ends 442 of the elastic member 44 abut against the front plate 51. The front plate 51 has a screw hole 511 and two clamping holes 512 spaced apart from each other. The seat body 41 can be fixed to the front plate 51 by locking it in the screw hole 511 with a screw, and the tenon 414 is inserted into the clamping hole 512. The main plate 52 is used to carry the display 2000, and is arranged between the front plate 51 and the rear plate 53, and can rotate relative to the front plate 51 and the rear plate 53 with the first axis X1 as the center, so that the display can switch between vertical swing or horizontal swing. The rear plate 53 is a generally circular plate, which is arranged at the rear side of the main plate 52 and has two pivoting parts 531, the pivoting parts 531 are respectively pivoted to the rod 22, and the four stop washers 31 are respectively fixed to the opposite sides of the pivoting parts 531, so that the bearing plate unit 5 can tilt relative to the protruding neck 2 along the second axis X2. The accommodating space 54 is surrounded and defined by the front plate 51, the main plate 52 and the rear plate 53. The limiting holes 55 are formed on the main plate 52 at intervals and communicate with the accommodating space 54, and have a first end 551 and a second end 552 opposite to each other. The limiting holes 55 are formed on the main plate 52 at intervals in a manner of sandwiching 90 degrees with each other, but are not limited thereto. The stop block 56 is generally cylindrical and fixed to the back of the main plate 52. The stop plates 57 are formed to extend outward from the periphery of the rear plate 53 relative to each other, and are limited by the stop block 56 when the main plate 52 is rotated and transformed. The friction ring 58 is disposed between the front plate 51 and the main plate 52 , and between the main plate 52 and the rear plate 53 .

[0060] The following describes the operation of the supporting device 1000 of the present application. The supporting plate unit 5 can be relative to the protruding neck 2 along the second axis X2 at a first position ( Figure 8 and Fig. 9 ) and a second position ( Fig.10 and Fig.11 ) Figure 8 As shown, in the first position, the inclination angle of the carrier plate unit 5 relative to the convex neck 2 is -6 degrees, and the elastic member 44 constantly provides an elastic force, which tends to make the first wing block 433 of the pivoting member 43 abut against the front plate 51 of the carrier plate unit 5, and make the first wing block 433 accommodated in the limiting hole 55, and the second wing block 434 away from the convex block 23 of the convex neck 2. At this time, the first wing block 433 is limited by the first end 551 and the second end 552 of the limiting hole 55, and the carrier plate unit 5 can only rotate and transform itself within a first angle range with the first axis X1 as the center. The first angle range is determined by the size of the limiting hole 55, for example, the distance between the first end 551 and the second end 552 is only slightly larger than the width of the first wing block 433, and the first angle range is ±4 degrees, thereby limiting the display to be substantially maintained in, for example, a yaw state, but not limited thereto.

[0061] When the support plate unit 5 starts to tilt from the first position to the second position but does not enter the second position, Fig. 9 As shown, the protrusion 23 of the convex neck 2 begins to push the second wing 434 of the pivoting member 43 and links the connecting section 443 of the elastic member 44 to compress the winding portion 441 of the elastic member 44. When the elastic member 44 is gradually compressed, the first wing 433 of the pivoting member 43 will gradually move away from the limiting hole 55 until the inclination angle of the supporting plate unit 5 relative to the convex neck 2 changes to 18 degrees. At this time, the first wing 433 has not completely separated from the limiting hole 55, and a part of the first wing 433 is still limited by the first end 551 and the second end 552 of the limiting hole 55, and the first angle range is still ±4 degrees. In other words, the first position means that the inclination angle of the supporting plate unit 5 relative to the convex neck 2 is between -6 degrees and 18 degrees.

[0062] Continue to use the protrusion 23 of the protruding neck 2 to push the second wing block 434 of the pivoting member 43 until the inclination angle of the supporting plate unit 5 relative to the protruding neck 2 is 19 degrees. Fig.10 As shown, at this time, the carrier plate unit 5 is already in the second position, and the first wing block 433 of the pivoting member 43 is completely away from the limiting hole 55, that is, the first wing block 433 is no longer limited by the first end 551 and the second end 552 of the limiting hole 55, thereby the carrier plate unit 5 can be rotated and transformed within the second angle range, and the second angle range is greater than the first angle range. The second angle range can be determined by the stop block 56 and the stop plate 57, for example, the stop plates 57 are clamped 180 degrees each other and are limited by the stop block 56, that is, the second angle range can be ±90 degrees, and the position of the limiting hole 55 formed on the main board 52 can correspond to the second angle of -90, 0, +90 degrees, that is, it can correspond to the position of the display 2000 when it is swung vertically and horizontally.

[0063] like Fig.11 As shown, the protrusion 23 of the protruding neck 2 can continue to push the second wing 434 of the pivoting member 43 until the second wing 434 abuts against the front plate 51, at which time the inclination angle of the supporting plate unit 5 relative to the protruding neck 2 is 22 degrees. Therefore, the second position means that the inclination angle of the supporting plate unit 5 relative to the protruding neck 2 is between 19 degrees and 22 degrees.

[0064] After the display 2000 completes the vertical or horizontal swing operation, and when the first wing block 433 of the pivot member 43 is aligned with any of the limiting holes 55, the operable supporting plate unit 5 can be tilted from the second position to the first position, so that the protrusion 23 of the protruding neck 2 is away from the second wing block 434 of the pivot member 43, and the elastic member 44 rebounds, so that the first wing block 433 of the pivot member 43 is accommodated in the limiting hole 55.

[0065] In one embodiment, when the support plate unit 5 is tilted relative to the protruding neck 2, the tilting module 3 generates friction, whereby the support plate unit 5 can stop at any position between the first position and the second position, that is, can stop at any angle between -6 degrees and 22 degrees.

[0066] In summary, the support device of the present application is designed with a pivot control unit so that the support plate unit can have different self-rotation angle ranges at different inclination angles. At a specific inclination angle, the bottom edge of the display will be raised so that the display can be swung vertically or horizontally, thereby preventing the corner of the display from hitting the desktop during the transition between vertical and horizontal swing. The pivot control unit in the support device of the present application does not need to occupy a large space, thus avoiding the disadvantage of the prior art that the support frame must be enlarged, and the overall cost is low, which conforms to the trend of lightweight and miniaturization.
