The substrate 100 has a first hole 110, the first movable member 200 is disposed on the substrate 100 and is movable 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 is movable relative to the first movable member 200, and the second movable member 300 has a third hole 310. The adjustment device 1000 is disposed on a structure for mounting the electronic device, such as a mount, a wall hanger, or a wall panel, as shown in fig. 9 as a wall hanger 3100. When the electronic device is assembled, the screw 2000 is first inserted through the third hole 310 and then pre-fixed to the corresponding screw hole on 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 determined according to the temporary position of the electronic device after pre-fixing and the target position to be adjusted through the searching pattern (or referred to as a lookup table), 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 time, 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 with adjustable screw hole position of the 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 fixedly disposed on a structure for mounting the electronic device, firstly, a screw is used to penetrate through the third hole 310 and to be pre-fixed with a corresponding screw hole on the electronic device, so that the electronic device obtains a temporary position, a first target position of the first movable member 200 and a second target position of the second movable member 300 are detected according to a target position of the electronic device through a searching pattern (or a lookup table), then the screw 2000 is loosened to such an 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, the second movable member 300 is driven to move to the second target position, in this process, the electronic device gradually moves to the target position along with the movement of the first movable member 200 and the second movable member 300, and then the screw 2000 and the corresponding screw hole are locked again, so that the electronic device is fixed at the target position.

In practice, the third hole 310 of the second movable member 300 is matched with the screw 2000, so that the driving of the first movable member 200 and the second movable member 300 can 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 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 the electronic device is fixed on the target position.

After the electronic device is pre-fixed, the adjusting device 1000 of the present invention can finely adjust the positions of the first movable member 200 and the second movable member 300 by a single person under the condition that the structural object for erecting the electronic device bears the weight of the electronic device, so as to drive the electronic device to move to other target positions, thereby adjusting the positions of the electronic device without supporting the electronic device in coordination with other people. 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 gaskets and pressed by the bearing surface of the screw, so that the screws can not rotate or move any more. And because the eccentric wheel is used for providing the adjustment freedom degree, even if the eccentric wheel is subjected to strong impact or vibration 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 severe environments such as vehicles and ships.

In this embodiment, the first group of labels uses letters and the second group of labels uses numbers, but the present invention is not limited thereto, and the two groups of labels may use numbers, and the numbers need not be limited to integers, so long as the numbers are sufficient to indicate to which position of the group of labels the labels is directed.

In the embodiment, the first graph LUT1 is only an example, and in actual operation, the user can divide the first graph LUT1 into finer segments according to the actual accuracy requirement, but not limited to this.

The specification of the adjustment device 1000 or the housing near the device is printed with a first lookup table (in this embodiment, the first graphic lookup table LUT 1) in advance, as shown in fig. 3, for indicating 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 a plurality of adjustment points distributed in a circular range, and each adjustment point is marked with a first set of index marks and a second set of index mark adjustment values corresponding to the point. The reference number combination corresponding to the center point of the circular range of the LUT1 represents the top view and the bottom view of the adjusting device 1000 when the first eccentric gear 200 and the second eccentric gear 300 are rotated to the reference number combination, wherein the screw hole 310 is adjusted at the center point, i.e. the zero position, i.e. not going up and down or not going left and right, in fig. 5A and 5B.

The highest point index combination in the center 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 the highest with respect to the substrate 100, that is, adjusts the mounting and locking position of the display device to be a first distance d 12 times from the center point toward the direction. Fig. 4A and 4B are top and bottom views of the adjusting device in this state.

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

In addition, each point in the lookup table may have more than one label combination, which indicates that the plurality of label combinations all have the same fine tuning position, for example, A4, B4, C4, D4, E4, F4 indicated by the circle center in LUT1, indicates that the screw hole 310 is fixed at the center point regardless of any position a to F of the first eccentric gear 200 when the second eccentric gear rotates to 4; for example, the same points A5 and C3 in the figure indicate that both combinations of A5 and C3 can adjust the screw hole 310 to an offset distance of about 1 time the first distance d1 above and to the right of the center point.

In practical operation, when the electronic device is installed, one of the ways is to first turn all the sets of adjustment devices 1000 on the fixed structure to the center point for zero setting, that is, rotate the second adjustment 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 first set of marks is not limited. The electronic device is mounted with a fixing frame, after the fixing screws 2000 of each group of adjusting devices 1000 are pre-locked, the temporary positions of the electronic devices are observed at this time, whether fine adjustment is needed is determined, if a certain group of adjusting devices 1000 need to fine-adjust a certain distance in a certain direction, in the LUT1, after the required distance is moved from the central point to the required direction, the mark of the nearest mark point is searched. Then the fixing screw 2000 is loosened slightly, and then the user installs the hexagonal head with the electric screwdriver, the hexagonal head is placed in the hexagonal grooves of the first connecting portion 420 and the second connecting portion 520 in sequence, the electric screwdriver is pressed, the first eccentric gear 200 and the second eccentric gear 300 are rotated to the marks corresponding to the marking points by rotating the first adjusting member 400 and the second adjusting member 500, and then the fixing screw 2000 is locked again to complete the adjustment.

Example 1: when the electronic device is to be adjusted by the uppermost distance of 6mm, which corresponds to the adjustment of the third hole 310 by the uppermost distance of 6mm, that is, the adjustment of the screw 2000 by the uppermost distance of 6mm, that is, the point (r, θ) = (6, 0), looking up the first pattern look-up table LUT1 shows that the first target position of the first movable member 200 is the first mark 230 aligned with the 1 st mark (letter a) of the first group of marks on the substrate 100 (that is, the position where the designated position is the letter a is determined), and the second target position of the second movable member 300 is the 1 st mark (number 1) of the second group of marks (that is, the position where the second designated position is the number 1) aligned with the second mark 240 on the first movable member 200. The user can complete the adjustment by using the electric screwdriver to align the first mark 230 with the 1 st mark (letter a) of the first set of marks, and simultaneously align the 1 st mark (number 1) of the second set of marks with the second mark 240. The top and bottom views of the adjusted fixture are shown in fig. 4A and 4B.

Example 2: when the electronic device is to be adjusted to the zero position, which corresponds 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 points (0, 0), looking up the first pattern look-up table LUT1 indicates that the first target position of the first movable member 200 is that the first mark 230 is aligned with any mark 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 complete the adjustment by using the electric screwdriver to align the 4 th mark (number 4) of the second set of marks with the second mark 240 while the first mark 230 is aligned with any mark of the first set of marks. The top and bottom views of the adjusted fixture are shown in fig. 5A and 5B. In actual operation, when the third hole 310 is located at the zero position, the first movable member 200 and the second movable member 300 can be considered to be located at the initial position, i.e. the initial position of the third hole 310 when the screw and the corresponding screw are pre-fixed, i.e. the zero position in the first graph lookup table LUT 1.

Example 3: when the electronic device is to be adjusted to the point (3 mm,120 °) at the lower right corner, which corresponds to the point (3 mm,120 °) at the lower right corner of the third hole 310, that is, the point (r 3mm,120 °) at the lower right corner of the screw 2000, it is known that the first graphic lookup table LUT1 is queried that the first target position of the first movable member 200 is the first mark 230 aligned with the 2 nd mark (letter B) in the first set of marks, and the second target position of the second movable member 300 is the second mark 240 aligned with the 5 th mark (numeral 5) in the second set of marks; alternatively, the first target position of the first movable member 200 is the first mark 230 aligned with the fourth mark (letter D) of the first set of marks, and the second target position of the second movable member 300 is the second mark 240 aligned with the 3 rd mark (number 3) of the second set of marks. The user aligns the first mark 230 with the 2 nd mark (letter B) of the first set of marks using the electric screwdriver, while the 5 th mark (number 5) of the second set of marks is aligned with the second mark 240; alternatively, the adjustment may be accomplished by aligning the first indicia 230 with the fourth indicia (letter D) of the first set of indicia, while the 3 rd indicia (number 3) of the second set of indicia is aligned with the second indicia 240. The user can select one of the adjustment schemes according to the actual needs. The top and bottom views of the adjusted fixture are shown in fig. 6A and 6B.

In the fixing device 100 according to the first embodiment of the present invention, when the first movable member 200 moves relative to the substrate 100, the first limiting member 220 rotates in the first hole 110, so that the first movable member 200 moves relative to the substrate 100 to rotate along a fixed center. The present embodiment is different from the first embodiment in that the movement of the first movable member 200 'with respect to the base plate 100' is translational. That is, the first movable member 200' has only a relative motion of this degree of freedom of translation. 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 along the first sidewall 111' in the first hole 110' when the first movable member 200' moves relative to the substrate 100 '.

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

In the present embodiment, the first movable member 200 'is free to move in the second direction f2 before the screw 2000 is locked to the corresponding screw hole, and the second movable member 300' is similar to the second movable member 300 in the first embodiment.

Referring to fig. 9 to 10C, fig. 9 is a schematic diagram illustrating the adjusting device of the present invention when the adjusting device is used in an electronic device, and fig. 10A to 10C are enlarged partial 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 bracket 3100 is provided with a first adjusting device a1, a third adjusting device b1 and a fourth adjusting device b2; the second bracket 3200 is provided with a second adjusting device a2 corresponding to the first adjusting device a 1; meanwhile, the second rack 3200 is symmetrically provided with a fifth adjusting device (behind the rack 3200, not shown due to the view angle relationship) and a sixth adjusting device (behind the rack 3200, not shown due to the view angle relationship) corresponding to the third adjusting device b1 and the fourth adjusting device b 2.

In practical operation, two locking points can be completely positioned for two objects connected in a plane, but if one point already determines an x axis and a y axis, the other point can only be adjusted in a direction perpendicular to the connecting line of the two points, and the second point in the connecting line direction of the two points must be allowed to move freely before being locked, so that the manufacturing dimensional tolerance of the two objects can be absorbed.

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

As shown in fig. 9, 10A and 10C, the third adjusting device b1 is selected from the adjusting devices 1000 in the first embodiment, which has determined that the y-axis and the z-axis of the fixing screw 2000 on the third adjusting device b1 are positioned, 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 from the adjusting devices 1000 'in the second embodiment, and the first limiting member 200' in the fourth adjusting device b2 can move freely in the y-axis direction before unlocking. In this way, the matching of the third adjusting device b1 and the fourth adjusting device b2 realizes the positioning of three degrees of freedom, i.e., the y-axis, the z-axis and the pitch (rotation around the x-axis) of the electronic device 3000. Similar to the third adjusting device b1 and the fourth adjusting device b2, the fifth adjusting device is the adjusting device 1000 in the first embodiment, and the Liu adjusting device is the adjusting device 1000' in the second embodiment, so that the matching of the fifth adjusting device and the sixth adjusting device realizes the y-axis, the z-axis and the pitching positioning of the other side of the electronic device 3000.

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

The adjusting device of the adjustable screw hole is used for adjusting the electronic device and can finely adjust the position of the electronic device before fixing the electronic device so as to enable the position of 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, the electronic device can be directly adjusted by a single person holding an adjusting tool (such as an electric screwdriver) under the weight load of the electronic device, and the electronic device does not need to be supported by other people, so that convenience is brought to the operation of workers, especially the operation of high-altitude areas or narrow areas, and the problem that the position cannot be accurately adjusted due to the elastic deformation of the stress of the fixing frame can be avoided.

2. After the adjustment is completed, the electronic device can not shift even if the electronic device is subjected to strong impact or vibration, and the electronic device is suitable for being used in severe environments such as vehicles, ships and the like. The reasons are as follows:

a. the eccentric wheel frame of the movable part is a wedge on a curved surface, and when the angle and the friction coefficient of the wedge mechanism are properly designed, the wedge mechanism cannot shift when being impacted by a large force, and correspondingly, the eccentric wheel is not easy to rotate to other angles due to the fact that the eccentric wheel is impacted by the diameter direction of a screw.

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

c. There are currently available on the market screws and runners for adjusting the position of an electronic device. When the electronic device is impacted or continuously vibrated, the screw rod and the sliding groove are easy to damage and deform due to the small threaded contact surface, so that reliability is not easy to ensure, and readjustment is difficult due to easy damage.

3. Because the movable pieces are all sheets, the space occupied by the thickness direction lock is smaller, so that the electronic device can be closer to the target wall surface (such as a wall surface, a ceiling and the like) when the electronic device is installed.

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

Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
