The adjusting device 1000 for adjusting the position of the screw hole of the present invention is used for fixing an electronic device (for example, the display device in fig. 9), and the adjusting device 1000 includes a substrate 100, a first movable member 200, and a second movable member 300. The substrate 100 has a first hole 110, the first movable member 200 is disposed on the substrate 100 and can move relative to the substrate 100, and the first movable member 200 has a second hole 210. The second movable member 300 is disposed on the first movable member 200 and can move relative to the first movable member 200, and the second movable member 300 has a third hole 310. The adjusting device 1000 is disposed on a structure on which the electronic device is mounted, such as a fixing frame, a wall mount or a wall panel, for example, the wall mount 3100 in fig. 9. When the electronic device is erected, the screw 2000 is firstly pre-fixed with the corresponding screw hole on the electronic device after passing through the third hole 310, the first target position of the first movable member 200 and the second target position of the second movable member 300 are determined by looking up the pattern (or looking up the table) according to the temporary position after the electronic device is pre-fixed and the target position to be adjusted, then the screw 2000 is loosened to the extent that the first movable member 200 and the second movable member 300 can be rotated or moved, the first movable member 200 is driven to move to the first target position relative to the substrate 100, the second movable member 300 is driven to move to the second target position relative to the first movable member 200, at this moment, the third hole 310 is moved to the target position, and finally the screw 2000 is completely locked again to complete the positioning. In this embodiment, the screw 2000 may be a VESA mount screw.

The adjusting device 1000 capable of adjusting the position of the screw hole of the present invention can finely adjust the position of the electronic device to reach the target position when the electronic device is fixed. Specifically, the adjusting device 1000 is fixed on a structure on which the electronic device is mounted, and is pre-fixed by screws passing through the third holes 310 and corresponding screw holes on the electronic device to temporarily position the electronic device, the first target position of the first movable member 200 and the second target position of the second movable member 300 are found out by the lookup pattern (or lookup table) according to the target position of the electronic device, then the screw 2000 is loosened to the extent that the first movable member 200 and the second movable member 300 are rotated or moved, the first movable member 200 is driven to move to the first target position, the second movable member 300 is driven to move to the second target position, in this process, the electronic device gradually moves to its target position with the movement of the first movable member 200 and the second movable member 300, the screws 2000 are then tightened again with the corresponding screw holes so that the electronic device is fixed to the target position.

In practical operation, the size of the third hole 310 of the second movable member 300 is matched with the screw 2000, and driving the first movable member 200 and the second movable member 300 to move can also be regarded as adjusting the position of the third hole 310. In other words, the target position of the corresponding screw hole on the electronic device can also be regarded as the target position of the third hole 310, and when the third hole 310 reaches the target position along with the movement of the first movable member 200 and the second movable member 300, the locking screw 2000 can be regarded as that the electronic device is fixed to the target position.

According to the adjusting device 1000 capable of adjusting the screw hole position, after the electronic device is pre-fixed, under the condition that a structure for erecting the electronic device bears the weight of the electronic device, a single person can finely adjust the positions of the first movable member 200 and the second movable member 300 to drive the electronic device to move to the target position, so that the position of the electronic device can be adjusted without supporting the electronic device in a cooperative manner by other persons. After the position is adjusted, the screw 2000 is locked with the corresponding screw hole, and at this time, the first movable member 200 and the second movable member 300 can be regarded as spacers and compressed by the bearing surface of the screw, so that they can not rotate or move any more. And because the eccentric wheel is used for providing the adjustment freedom degree, even if strong impact or vibration is applied in the subsequent use, the eccentric wheel is not easy to rotate to other angles due to the radial stress of the screw, so that the position of the electronic device cannot be changed, and the electronic device is suitable for being installed in the harsh environments of vehicles, ships and the like.

The first eccentric gear 200 is further printed with a second mark 240, the first mark 240 may be a second arrow, the second eccentric gear 300 is printed with a second set of marks, for example, including a1 st mark to an M th mark, the second set of marks are distributed around the outer edge of the second eccentric gear 300, when the second eccentric gear 300 rotates to different angles relative to the second opening 210 rotatably sleeved with the second eccentric gear, the second mark 240 points to different positions of the second set of marks, that is, the second set of marks and the second mark 240 may display the rotation angle of the second eccentric gear 300 relative to the second opening 210.

For the sake of illustration, the first group of labels uses letters and the second group of labels uses numbers, but the invention is not limited thereto, and the numbers may also use numbers for both groups of labels, and the numbers are not limited to integers, as long as it is sufficient to express the position of the group of labels to which the label points.

In this embodiment, the first graphic look-up table LUT1 is only an example, and in actual operation, the user can divide the first graphic look-up table LUT1 into more fine divisions according to actual accuracy requirements, which is not limited thereto.

A first lookup table (in this embodiment, a first graphic lookup table LUT1) is printed on the specification of the adjustment apparatus 1000 or a nearby housing of the apparatus in advance, as shown in fig. 3, to indicate the corresponding third hole position adjustment amount when the first mark 230 and the second mark 240 rotate to different mark positions.

The LUT1 is distributed over a circular range for a plurality of adjustment points, each of which is labeled with a first set of index and a second set of index adjustment values corresponding to the point. The reference number combination corresponding to the center point of the circular range of the LUT1 represents that when the first eccentric gear 200 and the second eccentric gear 300 are rotated to the reference number combination, the adjusting device 1000 adjusts the screw hole 310 to the center point, i.e. to the zero position, i.e. not to the upper or lower or left or right, and fig. 5A and 5B are top and bottom views of the adjusting device in this state.

The central highest point index combination of the LUT1 represents that when the first eccentric gear 200 and the second eccentric gear 300 are rotated to the index combination, the adjusting device 1000 adjusts the screw hole 310 to be highest with respect to the substrate 100, i.e., the mounting and locking position of the display device is adjusted to the first distance d 12 times from the central point in the direction. Fig. 4A and 4B are top and bottom views of the adjustment device in this state.

The point reason of the rest positions is the same, so the description is omitted: which direction and which distance a point is in the circular range represents which direction and which distance the adjusting device 1000 adjusts the screw hole 310 to be offset from the center point with respect to the substrate 100. Fig. 6A and 6B are top and bottom views of the adjustment device in some other state.

Each point in the lookup table may have more than one index combination, which means that the index combinations all have the same fine tuning position, for example, a4, B4, C4, D4, E4, F4 marked by the circle center in LUT1, which means that when the second eccentric gear rotates to 4, the screw hole 310 is fixed at the central point regardless of the positions of a to F of the first eccentric gear 200; also for example, a5 is the same as C3, indicating that both a5 and C3 combinations can adjust the screw hole 310 to an offset distance of about 1 times the first distance d1 to the upper right of the center point.

In practical operation, when the electronic device is installed, one way is to rotate all the sets of adjusting devices 1000 on the fixed structure to the center point and return to zero, i.e. rotate the second adjusting member 500 to drive the second eccentric gear 300 until the second mark 240 points to 4 of the second set of marks, and the position of the first set of marks is not limited. The electronic device is mounted on the fixing frame, the fixing screws 2000 of each set of adjusting devices 1000 are pre-fastened, the temporary position of the electronic device is observed, whether fine adjustment is needed or not is determined, if a certain set of adjusting devices 1000 need to perform fine adjustment for a certain distance in a certain direction, in the lookup LUT1, after the central point moves the needed distance in the needed direction, the label of the marking point closest to the central point is searched. Then, the fixing screw 2000 is slightly loosened, and then the user mounts the hexagonal head on the electric screwdriver, the hexagonal head is sequentially placed in the hexagonal grooves of the first connecting portion 420 and the second connecting portion 520, the electric screwdriver is pressed, the first adjusting member 400 and the second adjusting member 500 are rotated, the first eccentric gear 200 and the second eccentric gear 300 are rotated to the mark corresponding to the marked point, and the fixing screw 2000 is locked again to complete the adjustment.

Example 1: when the electronic device is adjusted to the uppermost distance of 6mm, which is equivalent to the third hole 310 is adjusted to the uppermost zero point of 6mm, that is, the screw 2000 is adjusted to the uppermost zero point of 6mm, that is, the point (r, θ) is (6, 0), the first pattern lookup table LUT1 is searched, and the first target position of the first movable member 200 is that the first mark 230 is aligned with the 1 st mark (letter a) in the first group of marks on the substrate 100 (i.e., the position where the designated position is determined to be the letter a), and the second target position of the second movable member 300 is that the 1 st mark (number 1) in the second group of marks (i.e., the position where the second designated position is the number 1) is aligned with the second mark 240 on the first movable member 200. The user can use the electric screwdriver to align the first mark 230 with the 1 st mark (letter a) in the first set of marks, and simultaneously align the 1 st mark (number 1) in the second set of marks with the second mark 240 to complete the adjustment. Fig. 4A and 4B show top and bottom views of the adjusted fixing device.

Example 2: when the electronic device is adjusted to the zero position, which is equivalent to the adjustment of the third hole 310 to the zero position, i.e. the adjustment of the screw 2000 to the zero position, i.e. the point (0, 0), the first pattern look-up table LUT1 is searched, the first target position of the first movable member 200 is that the first mark 230 is aligned with any one of the first set of marks on the substrate 100, and the second target position of the second movable member 300 is that the second mark 240 is aligned with the 4 th mark (number 4) of the second set of marks on the second movable member 300. The user can use the electric screwdriver to align the 4 th mark (number 4) in the second set of marks with the second mark 240, and simultaneously align the first mark 230 with any one of the first set of marks to complete the adjustment. Fig. 5A and 5B show top and bottom views of the adjusted fixing device. In practice, the third hole 310 may be considered to be located at the initial position when the first movable member 200 and the second movable member 300 are located at the zero position, i.e. the zero position in the first graphic look-up table LUT1 when the screws and the corresponding screws are pre-fixed.

Example 3: when the electronic device is adjusted to the lower right corner (3mm, 120 °), which is equivalent to the lower right corner (3mm, 120 °), i.e. the screw 2000 is adjusted to the lower right corner (r3mm, θ 120 °), the first graphic look-up table LUT1 is queried, and the first target position of the first movable member 200 is such that the first mark 230 is aligned with the 2 nd mark (letter B) in the first group of marks, and the second target position of the second movable member 300 is such that the second mark 240 is aligned with the 5 th mark (number 5) in the second group of marks; alternatively, the first target position of the first movable member 200 is such that the first mark 230 is aligned with the fourth mark (letter D) in the first group of marks, and the second target position of the second movable member 300 is such that the second mark 240 is aligned with the 3 rd mark (number 3) in the second group of marks. The user aligns the first mark 230 with the 2 nd mark (letter B) in the first set of marks using the power driver, while the 5 th mark (numeral 5) in the second set of marks is aligned with the second mark 240; alternatively, the adjustment may be accomplished by aligning the first mark 230 with the fourth mark (letter D) in the first set of marks while aligning the 3 rd mark (number 3) in the second set of marks with the second mark 240. The user can select one of the adjusting schemes according to the actual requirement. Fig. 6A and 6B show top and bottom views of the adjusted fixing device.

Referring to fig. 7A to 8B, fig. 7A is a perspective view of a fixing device capable of adjusting a position of a screw hole according to a second embodiment of the present invention; FIG. 7B is a schematic view of the fixing device of FIG. 7A from another perspective; FIG. 8A is an exploded view of the fastening device of FIG. 7A; fig. 8B is an exploded view of the fastening device of fig. 7A from another perspective.

In the fixing device 100 according to the first embodiment of the invention, when the first movable element 200 moves relative to the substrate 100, the first limiting element 220 rotates in the first hole 110, so that the first movable element 200 rotates along a fixed center relative to the substrate 100. The present embodiment is different from the first embodiment in that the movement of the first movable member 200 'with respect to the substrate 100' is a translation. That is, the first movable member 200' has only a relative motion of translational degree of freedom. As shown in fig. 7A to 8B, the first hole 110 ' has a first sidewall 111 ' extending along the second direction f2, and the first limiting member 220 ' translates in the first hole 110 ' along the first sidewall 111 ' when the first movable member 200 ' moves relative to the substrate 100 '.

In this embodiment, the first hole 110 ' further has a second sidewall 112 ' extending along the second direction f2, the first sidewall 111 ' is parallel to the second sidewall 112 ' and has a third distance, and the first position-limiting member 220 ' on the first movable member 200 ' has a dimension in the first direction f1 matching the third distance, so that when the fixing device 1000 ' is in use, the first position-limiting member 210 ' is located in the second hole 210 ' and is attached to the first sidewall 111 ' and the second sidewall 112 '.

In this embodiment, the first movable member 200 'can move freely along the second direction f2 before the screw 2000 is locked with the corresponding screw hole, and the second movable member 300' operates in a similar manner to the second movable member 300 in the first embodiment.

Referring to fig. 9 to 10C, fig. 9 is a schematic view illustrating an adjusting device of the present invention in an electronic device, and fig. 10A to 10C are enlarged partial schematic views of fig. 9. The fixing frame of the electronic device 3000 may include a first frame 3100 and a second frame 3200. In this embodiment, the electronic device is a flat panel display device. As shown in fig. 9, the first frame 3100 is provided with a first adjustment device a1, a third adjustment device b1 and a fourth adjustment device b 2; the second holder 3200 is provided with a second adjusting device a2 corresponding to the first adjusting device a 1; meanwhile, the second holder 3200 is symmetrically provided with a fifth adjusting device (not shown due to a view angle relationship behind the holder 3200) and a sixth adjusting device (not shown due to a view angle relationship behind the holder 3200) corresponding to the third adjusting device b1 and the fourth adjusting device b 2.

In practice, two locking points can be positioned completely for two objects connected in a plane, but if one point determines the x-axis and the y-axis, the other point can only be adjusted in the direction perpendicular to the connecting line of the two points, and the second point in the direction of the connecting line of the two points must be allowed to move freely before locking, so as to absorb the manufacturing dimensional tolerance of the two objects.

As shown in fig. 9, 10A and 10B, the first adjusting device a1 is selected as the adjusting device 1000 of the first embodiment, which can determine the x-axis and y-axis two-axis positioning of the fixing screw 2000 on the first adjusting device a1, at this time, the second adjusting device a2 must only allow fine adjustment of the y-axis of the fixing screw 2000 on the second adjusting device a2, corresponding to the leveling (or left-right tilting, or rotation around the z-axis) of the electronic device, and the second adjusting device a2 must allow free movement of the fixing screw 2000 in the x-axis direction before locking, so that the second adjusting device a2 is selected as the adjusting device 1000 'of the second embodiment, and the first limiting member 200' in the second adjusting device a2 can move freely in the x-axis direction before locking. In this way, the first adjustment device a1 and the second adjustment device a2 are matched to position the electronic device 3000 in three degrees of freedom, i.e., x-axis, y-axis and horizontal (left-right tilting) corresponding to the fixing frame set. On the contrary, if the first adjustment device a1 and the second adjustment device a2 both use the adjustment device 1000, it will happen that when the adjustment devices are at certain set positions, the distance between the 2 fixing screw holes 310 on the first adjustment device a1 and the second adjustment device a2 is not equal to the distance between the corresponding 2 screw holes on the electronic device, so that the 2 fixing screws 2000 cannot be simultaneously locked into the electronic device through the aligned holes.

As shown in fig. 9, 10A and 10C, the third adjusting device b1 is selected as the adjusting device 1000 of the first embodiment, which has determined the y-axis and z-axis two-axis positioning of the fixing screw 2000 on the third adjusting device b1, then the fourth adjusting device b2 must only allow fine adjustment of the z-axis of the fixing screw 2000 and allow free movement in the y-axis direction before locking, so that the fourth adjusting device b2 is selected as the adjusting device 1000 'of the second embodiment, and the first limiting member 200' in the fourth adjusting device b2 can move freely in the y-axis direction before locking. In this way, the third adjustment device b1 and the fourth adjustment device b2 are matched to realize the positioning of the electronic device 3000 in three degrees of freedom, namely, the y-axis, the z-axis and the pitch (rotating around the x-axis). Similar to the third adjusting device b1 and the fourth adjusting device b2, the fifth adjusting device is the adjusting device 1000 of the first embodiment, and the sixth adjusting device is the adjusting device 1000' of the second embodiment, so that the fifth adjusting device and the sixth adjusting device are matched to realize the y-axis, z-axis and pitch positioning of the other side of the electronic device 3000.

The adjusting device capable of adjusting the screw hole can be assembled to form an adjusting device capable of realizing two-axis fine adjustment or single-axis fine adjustment through different element combinations. When the positioning device is specifically applied to an electronic device, the electronic device can be positioned in a plurality of axial directions through different adjustment device combinations. When being applied to the tiled display field, not only can make the gap between a plurality of display panels less through the location of x axle and y axle, can ensure that the display surface of a plurality of display panels is located the coplanar through the location of z axle moreover to ensure tiled display screen's display effect.

The adjusting device capable of adjusting the screw hole is used for adjusting the electronic device and can finely adjust the position of the electronic device before the electronic device is fixed so as to enable the electronic device to reach a target position. Compared with other schemes in the market, the method has the following advantages:

1. after the electronic device is pre-fixed, a single person can adjust the electronic device by holding an adjusting tool (such as an electric screw driver) with hands without the assistance of other people when the fixing frame of the electronic device bears the weight load of the electronic device, the operation of workers, particularly the operation in a high area or a narrow area, is facilitated, and the problem that the position of the fixing frame cannot be accurately adjusted due to elastic deformation caused by stress can be avoided.

2. After the adjustment is completed, even if strong impact or vibration is applied, the electronic device does not have position deviation, and is suitable for being used in severe environments such as vehicles, ships and the like. The reason is as follows:

a. the eccentric wheel framework of the movable piece is a wedge on the curved surface, and when the angle and the friction coefficient of the wedge mechanism are properly designed, the wedge mechanism can not shift when bearing larger impact force, and the eccentric wheel is not easy to rotate to other angles due to the fact that the eccentric wheel bears the impact force of the screw in the diameter direction.

b. When the screw is locked, the position of the movable piece is equivalent to the gasket of the screw, and the movable piece is pressed at the bottom at the screw locking moment and can not rotate any more, so that the movable piece can not deviate any more after being positioned.

c. The position of an electronic device is adjusted by a screw rod and a sliding groove in the existing market. When the electronic device is impacted or continuously vibrated, the screw rod and the sliding groove are easily damaged and deformed due to a small thread contact surface, the reliability is not easily ensured, and the screw rod and the sliding groove are easily damaged to cause the difficulty of readjustment.

3. Because the movable parts used are all sheets, the space occupied by the lock in the thickness direction is smaller, and the electronic device can be closer to a target wall surface (such as a wall surface, a ceiling and the like) after being installed.

4. The adjusting device is manufactured by using a plane sheet metal part and a screw manufacturing process, so that the adjusting device is low in cost and convenient to manufacture.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
