As shown in FIG. 2, where 1 is the entrance of a square light bar and 2 is the spot, spot 2 would typically be larger than the entrance of square light bar 101. The central light intensity of the light spot is larger than the edge light intensity, and the light spot 2 is required to be in the central position of the entrance of the square light bar 101 due to the requirement of the rear lighting system on the light angle. However, due to assembly and material errors, the light spot is generally off center with respect to the square light bar 101 and needs to be adjusted.

At present, the main scheme of adjustment is to adjust the element 100 to be adjusted by adjusting the position of the element 100 to be adjusted or the square light bar 101, for example, by leaving a space in two directions above and on the right side, so that a tool or a human hand can reach the space, which is a waste of space due to the reservation of space when the design is needed, and if the space is insufficient, the adjustment is hindered, and the position of the light spot is not good.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, the position of the lens is adjusted in two directions (two-dimensional adjustment), so that a space in two directions is needed, however, the space reservation in two directions may cause a waste of space, especially in the present projector with simple structure and small size, if the space is insufficient, the adjustment may be hindered, and the position of the light spot may be not good.

Based on the above, the adjusting device can be arranged at the element to be adjusted, the element to be adjusted can rotate along with the first adjusting component through the two adjusting components when the first adjusting component rotates, and can transversely move, and the first adjusting component and the element to be adjusted can be pulled to longitudinally move when the second adjusting component moves, so that two-dimensional adjustment on the same dimension is realized, and the situations of inconvenience in adjustment and waste of adjusting space caused by two-dimensional adjustment in different dimensions in the prior art are relieved.

The following detailed description is made with reference to the accompanying drawings:

the invention provides an adjusting device, which is arranged at an element to be adjusted of a projector and used for adjusting the position of the element to be adjusted, and particularly, as shown in fig. 1, the element to be adjusted can be a converging element, light emitted by a light source is irradiated in the element 100 to be adjusted, and the light is converged by the element 100 to be adjusted and projected in a square light bar 101, wherein the adjusting device can be arranged at the element 100 to be adjusted and used for adjusting the position of the element 100 to be adjusted so as to project a light spot converged by the element 100 to be adjusted at the central position of the square light bar 101. The converging element may be a single lens, such as a convex lens, or may be a combination of lenses, such as a combination of lenses including a collimating lens and a convex lens. Of course, the adjusting device may be disposed at the square light bar 101, etc., and the invention is not limited to the element to be adjusted.

When the element to be adjusted is not an element distributed in central symmetry, the first adjusting component normally rotates.

When the elements to be adjusted are centrosymmetrically distributed, a certain offset exists between the center of the element to be adjusted 100 and the rotation center of the first adjusting member 110, so that the element to be adjusted is pulled to move transversely when the first adjusting member rotates. For example, the center of the element 100 to be adjusted is not located at the same position as the rotation center of the first adjusting member 110, and when the amount of deviation is large, the amount of lateral movement of the element 100 to be adjusted is relatively large when the first adjusting member 110 is rotated, and when the amount of deviation is small, the amount of lateral movement of the element 100 to be adjusted is relatively small when the first adjusting member 110 is rotated.

The adjusting device comprises: a first adjustment member and a second adjustment member; the motion mode is as follows: when the first adjusting component rotates, the element to be adjusted is dragged to move transversely; when the second adjusting component moves, the element to be adjusted is dragged to move longitudinally. Wherein, the transverse motion can be transverse bending motion, and the longitudinal motion can be longitudinal vertical motion. Longitudinal motion has injectd the second adjustment part and has moved in certain dimension, but because first adjustment part is rotary motion, rotary motion is a motion that can rotate 360 degrees, also can understand that rotary motion can all can rotate in arbitrary one dimension, so can realize first adjustment part and second adjustment part and move in same dimension, can satisfy and carry out two-dimentional (horizontal and vertical) adjustment in same dimension, the condition that adopts different dimensions to carry out two-dimensional adjustment and cause the inconvenience of adjustment and adjustment space waste among the prior art has been alleviated.

The structure in which the first adjusting member and the second adjusting member are each connected to the element to be adjusted may include: as shown in fig. 3a, the first adjusting component 110 is fixedly connected to the element to be adjusted 100, and the first adjusting component 110 is movably connected to the second adjusting component 120. Further comprising: as shown in fig. 3b, the second adjusting component 120 is fixedly connected to the element to be adjusted 100, and the first adjusting component 110 is movably connected to the second adjusting component 120.

The movement of the structure shown in fig. 3a is that when the first adjusting member 110 rotates, the element to be adjusted 100 is pulled to move laterally, and the second adjusting member 120 does not move; when the second adjusting member 120 moves, the first adjusting member 110 and the element to be adjusted 100 are pulled to move longitudinally.

In fig. 3a, taking a two-dimensional space as xy as an example, a first direction of the two-dimensional space is an x direction, and a second direction of the two-dimensional space is a y direction, when the first adjusting member 110 rotates, the element to be adjusted 100 is pulled to move laterally, that is, move in the x direction, and when the second adjusting member 120 moves, the first adjusting member 110 and the element to be adjusted 100 are pulled to move longitudinally, that is, move in the y direction.

The movement of the structure shown in fig. 3b is such that when the second adjusting member 120 moves, the element to be adjusted 100 is pulled to move longitudinally, and the first adjusting member 110 does not move; when the first adjusting member 110 rotates, the second adjusting member 120 is pulled to move transversely with the element 100 to be adjusted.

In fig. 3b, taking a two-dimensional space as xy as an example, a first direction of the two-dimensional space is an x direction, a second direction of the two-dimensional space is a y direction, when the second adjusting member 120 moves, the element to be adjusted 100 is pulled to move longitudinally, that is, move in the y direction, and when the first adjusting member 110 moves, the second adjusting member 120 and the element to be adjusted 100 are pulled to move transversely, that is, move in the x direction.

For the configuration of FIG. 3a, the first adjustment member may include elements such as, as shown in connection with FIG. 4, a fixed bracket 111 and a first handle 112; the element 100 to be adjusted is fixed in the fixed bracket 111, the first handle 112 is connected with the fixed bracket 111, and when the first handle 112 is pulled, the fixed bracket 111 rotates, wherein a certain offset is provided between the rotation center of the fixed bracket 111 and the center of the element 100 to be adjusted.

As shown in fig. 5a and 5b, the dashed line is a movement track of the center p of the element 100 to be adjusted, wherein the arc size of the movement track of the dashed line is related to the offset amount, that is, when the offset amount is large, the displacement of the element 100 to be adjusted is relatively large when the fixed bracket 111 rotates, and when the offset amount is small, the displacement of the element 100 to be adjusted is relatively small when the fixed bracket 111 rotates at the same rotation angle.

Wherein the size of the fixing support 111 may be larger than the size of the element 100 to be adjusted with respect to the size. As to the shape, the shape of the fixing bracket 111 may match the shape of the element to be adjusted 100, i.e. taking the element to be adjusted 100 as a circular convex lens as an example, the shape of the fixing bracket 111 may also be circular, of course, the shape of the element to be adjusted 100 may be square, and the shape of the fixing bracket 111 may also be square. Therefore, the shape and the size of the fixed support are not particularly limited, the element to be adjusted can be fixed in the fixed support, the first handle is connected with the fixed support, and when the first handle is pulled, the fixed support rotates. Alternatively, the shape, size, connection relationship, and the like of the fixing bracket 111 and the element to be adjusted may be similar to those of a camera lens and its bracket.

Referring to fig. 5a, when the first handle 112 is moved leftward in the x direction, and the fixed bracket 111 rotates leftward around the rotation center, the fixed bracket 111 pulls the element to be adjusted 100 to rotate leftward, and the center p of the element to be adjusted 100 moves in an arc leftward, so that the position of the element to be adjusted moves leftward in the x direction (one dimension).

Similarly, referring to fig. 5b, when the first handle 112 is moved to the right in the x direction, and the fixed bracket 111 rotates to the right around the rotation center, the fixed bracket 111 pulls the element to be adjusted 100 to rotate to the right, and the center p of the element to be adjusted 100 moves to the right along the arc-shaped movement track, so that the position of the element to be adjusted moves to the right in the x direction (the first dimension).

For the structure shown in fig. 3a, the first adjusting component may include, as shown in fig. 4, a moving slider 121 and a second handle 122, where the moving slider 121 has a groove structure for placing the fixing bracket 111, and the second handle 122 and the first handle 112 are both placed on the same side, i.e. in one dimension, when the second handle 122 is pulled, the moving slider 121 pulls the first adjusting component 110 and the element to be adjusted 100 to move longitudinally.

Wherein, as for the size, the size of the moving slider 121 may be larger than that of the fixing bracket 111. As for the shape, the shape of the moving slider 121 may match the shape of the fixing bracket 111, that is, when the fixing bracket 111 is circular, the shape of the moving slider 121 may be circular, and of course, the shape of the moving slider 121 may not match the shape of the fixing bracket 111, that is, as shown in fig. 4, the shape of the fixing bracket 111 is circular and the shape of the moving slider 121 is square. Therefore, the shape and size of the movable slider 121 are not particularly limited, and the movable slider has a groove structure for placing the fixed bracket, so that when the second handle is pulled, the movable slider can drive the first adjusting component and the element to be adjusted to move longitudinally.

As shown in fig. 6a, when the second handle 122 is pulled to move downwards in the y direction, and the moving slider 121 moves downwards in the y direction, since the moving slider 121 has a groove structure for placing the fixing bracket 111, and the fixing bracket 111 fixes the element to be adjusted 100, when the moving slider 121 moves downwards in the y direction, the element to be adjusted 100 also moves downwards, that is, the center p of the element to be adjusted 100 moves downwards, so that the position of the element to be adjusted is adjusted to be shifted downwards in the y direction (second dimension).

Similarly, as shown in fig. 6b, when the second handle 122 is pulled to move upward in the y direction, and the moving slider 121 moves upward in the y direction, since the moving slider 121 has a groove structure for placing the fixing bracket 111, and the fixing bracket 111 fixes the element to be adjusted 100, when the moving slider 121 moves upward in the y direction, the element to be adjusted 100 also moves upward, that is, the center p of the element to be adjusted 100 moves upward, so that the position of the element to be adjusted is adjusted to be shifted upward in the y direction (second dimension). The element shown in fig. 4 can realize two-dimensional adjustment in the same dimension, and alleviates the problem of inconvenient adjustment and wasted adjustment space caused by two-dimensional adjustment in different dimensions in the prior art.

Alternatively, the fixed bracket 111 may be connected to the element 100 to be adjusted in a similar manner to a camera lens and its bracket.

A first sliding member 130 is disposed between the first adjusting member 110 and the second adjusting member 120, and the first sliding member 130 is mounted on the second adjusting member 120 so that the first adjusting member 110 can rotate in the second adjusting member 120. Optionally, lubricating oil or damping oil may be filled in the groove of the second adjusting member 120, so that the rotation is smoother.

Referring to fig. 7, the first slider 130 may be disposed in a groove of the movable slider 121 where the fixed bracket 111 is located, wherein the first slider includes a plurality of steel balls, and in fig. 7, taking three steel balls as an example, in the groove of the movable slider 121, the fixed bracket 111 may not move through the movable slider 121, but may perform a rotation motion through the three steel balls, so that the fixed bracket 111 alone performs a rotation motion to pull the element to be adjusted 100 to rotate. When the movable slider 121 moves, the steel balls do not rotate, and thus the movable slider 121 can drive the fixed bracket 111 and the element 100 to be adjusted to move up and down together.

Referring to fig. 4 again, the adjusting device further includes: a fixing base 140, wherein the fixing base 140 is used for fixing the second adjusting member 120.

Wherein, regarding the size, the size of the fixed base 140 may be larger than that of the movable slider 121. As for the shape, the shape of the fixed base 140 may match with the shape of the moving slider 121, that is, when the moving slider 121 is square, the shape of the fixed base 140 may be square, and of course, the shape of the fixed base 140 may not match with the shape of the moving slider 121, that is, as shown in fig. 4, the shape of the moving slider 121 may be square, and the shape of the fixed base 140 may be circular. Therefore, the shape and the size of the fixed base are not particularly limited, and the requirement that the fixed base is used for fixing the second adjusting component can be met.

Referring to fig. 7, the second adjusting member 120 and the fixing base 140 include: a second sliding part 150, so that the second adjusting component 120 can move and be fixed when moving up and down in the fixing base 140, wherein the second sliding part 150 includes a spring plate or a sliding rail.

In detail, the second sliding member 150 may be fixed on the fixed base 140, and when the second sliding member may include a plurality of resilient sheets or springs, the resilient sheets or springs may be disposed on two sides of the moving slider, for example, two resilient sheets are installed on the right side shown in fig. 7, and relatively speaking, two resilient sheets may be installed on the left side to fix the moving slider 121, and the moving slider 121 may also be moved up and down by pulling the second handle 122. When the second slider may include a slide rail, the slide rail may be disposed at the bottom of the moving slider and disposed along the y direction, and the moving slider 121 is moved up and down by pulling the second handle 122.

It can be clearly understood by those skilled in the art that, for convenience and brevity of description, the specific working process of the adjustment apparatus described in this embodiment may refer to the corresponding process in the foregoing embodiment, and is not described herein again.

The projector provided by the invention can be provided with the adjusting device at the position of the element to be adjusted, the adjusting device comprises the first adjusting part and the second adjusting part, the first adjusting part can be fixed with the element to be adjusted, the first adjusting part is movably connected with the second adjusting part, when the first adjusting part rotates, the second adjusting part is not moved, the element to be adjusted can rotate along with the first adjusting part, and when the second adjusting part moves in the same space, the first adjusting part and the element to be adjusted can be dragged to move longitudinally, so that the condition that the two-dimensional adjustment is carried out by adopting different spaces in the prior art, and the adjustment is inconvenient is relieved.
