The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

With reference to fig. 1 to 10, a direct-drive optical cutting imaging device according to a preferred embodiment of the present invention can be disposed on a light propagation path of a spotlight. Specifically, the direct-drive optical cutting imaging device forms a light through hole 101, wherein when the light through hole 101 is opened, the light radiated by the spotlight is allowed to pass through.

The direct-drive optical cutting imaging device comprises at least one substrate 10, at least one light blocking sheet 20 and at least one pair of linkage mechanisms 30. The middle of the substrate 10 forms a light passing hole 101.

The base plate 10 is provided with at least one shaft hole 102. The linkage mechanism 30 includes at least one bushing 31 and a linkage arm 32. The linkage arm 32 includes a swing arm 321 and a swing arm 322. The boss 31 is rotatably mounted to the shaft hole 102. One end of the rotating arm 321 of the linkage arm 32 is fixed to the shaft sleeve 31, so that after the shaft sleeve 31 is driven to rotate, the rotating arm 321 rotates correspondingly.

One end of the swing arm 322 is pivotally connected to the other end of the rotating arm 321. One side of the light blocking member 20 is rotatably connected to the other end of the swing arm 322. The other side of the light barrier 20 is rotatably connected to the swing arm 322 of the other of the linkages 30.

The sleeve 31 of each linkage 30 is directly coupled to an output shaft of a motor, in such a way that the sleeve 31 can be directly driven to rotate by the motor. The sleeve 31 then rotates the rotating arm 321. Accordingly, the swing arm 322 will bring the light barrier 20 to slide along the plane of the substrate 10.

The light barrier 20 is configured to slide to a position at least partially blocking the light passing hole 101, so that the light passing through the light passing hole 101 is partially blocked and an image formed by the light passing through the light passing hole 101 has a predetermined shape.

Preferably, at least two pairs of limiting columns 12 are arranged on the substrate 10. Two of the limiting columns 12 are disposed on a path of rotation of the rotating arm 321 of one of the linkages 20 to limit a magnitude of rotation of the rotating arm 321 connected to one side of the light-blocking sheet 20. When the rotating arm 321 rotates to abut against one of the limiting columns 12, the light blocking sheet 20 is far away from the limit position; when the light-blocking sheet 20 slides to the other limit position, the light-blocking sheet 20 slides to the other limit position that blocks the light-passing hole 101. The other two limiting columns 12 are disposed on the path of rotation of the rotating arm 321 of the other linkage 20 to limit the amplitude of rotation of the rotating arm 321 connected to the other side of the light barrier 20.

With this arrangement, the light-blocking sheet 20 can be kept sliding within a predetermined range on the one hand. On the other hand, because the light blocking sheet 20 can reduce the noise generated by the linkage arm 32 during the linkage process during the sliding process, the noise generated by the whole direct-drive optical cutting imaging device is reduced.

It is worth integrating that, when the rotating arm 321 is rotated by the bushing 31, the swing arm 322 rotates relative to the rotating arm 321, so that the angle between the swing arm 322 and the rotating arm 321 is adjusted, and the position of the side of the light blocking sheet connected to the swing arm 322 relative to the light passing hole 101 is adjusted.

Preferably, the direct-drive photo-cutting imaging device comprises four light-blocking sheets 20. Two of the light-blocking sheets 20 are oppositely disposed in a first lateral direction formed by the substrate 10, and the other two light-blocking sheets 20 are oppositely disposed in a second lateral direction formed by the substrate 10. The first lateral direction and the second lateral direction are perpendicular to each other, and two of the light-blocking sheets 20 located in the first lateral direction are stacked on another two of the light-blocking sheets 20 located in the second lateral direction.

Both sides of each of the light-blocking sheets 20 are individually swingably connected to one of the link mechanisms 30. That is, when the direct-drive type photo-cutting imaging device includes four light-blocking sheets 20, the direct-drive type photo-cutting imaging device includes 8 linkage mechanisms 30, so that both sides of each light-blocking sheet 20 can be driven to swing by the linkage mechanisms 30, respectively.

Further, at least one guide plate 40 is fixed on the base plate 10. An alignment hole is formed in the middle of the guide plate 40, wherein the alignment hole is disposed to be aligned with the light passing hole 101 for light to pass through. The light blocking sheet 20 is sandwiched between the substrate 10 and the guide plate 40. At least one linear guide groove 401 is formed in the guide plate 40, and the middle portion of the light blocking sheet 20 connected to the link mechanism 30 is engaged with the guide groove 401. When the light blocking sheet 20 is swung by the link mechanism 30, the light blocking sheet 20 is restricted in the linear guide groove 401. In this way, irregular sliding of the light barrier 20 can be prevented on the one hand. On the other hand, by controlling the swing mechanisms 30 connected to both sides of the same light-blocking sheet 20 in a coordinated manner, the light-blocking sheet 20 can slide regularly, and the shape of an image formed by light passing through the light-passing hole 101 after being blocked by the light-blocking sheet 20 can be controlled.

It can be understood that, when the light blocking sheet 20 is driven by the linkage mechanism 30 to swing, the light blocking sheet can rotate around the position of the middle portion of the light blocking sheet 20 in the linear guide groove 401. Since the middle portion of the light blocking sheet 20 can slide along the linear guide groove 401, the center of the light blocking sheet 20 can be gradually changed. In this way, by controlling the position of the middle portion of the light-blocking sheet 20 in the linear guide groove 401, the area of the light-passing hole 101 blocked by the light-blocking sheet 20 can be changed. And the position for shielding the light passing hole 101 can be changed by swinging both sides of the light blocking sheet 20.

Preferably, when the direct-drive type photo-cutting imaging device includes four light-blocking sheets 20, the direct-drive type photo-cutting imaging device includes two guide plates 40, and two linear guide grooves 401 are provided on one of the guide plates 40, so that when the two light-blocking sheets 20 are driven by the linkage mechanism 30, the swinging circles of the light-blocking sheets can slide along the linear guide grooves 401. The other guide plate 40 is provided with two other linear guide grooves 401, so that when the other two light blocking plates 20 are driven by the link mechanism 30, the swinging circles thereof can slide along the linear guide grooves 401.

Preferably, a mounting gap is formed between the sleeve 31 and the base plate 10. A noise reducing bearing 33 is arranged in the mounting gap. When the sleeve 31 is driven to rotate by the driving motor, the noise reduction bearing 33 also rotates accordingly.

More preferably, the noise reduction type optical cutting imaging device further includes a window retracting and expanding mechanism 50, and the window retracting and expanding mechanism 50 includes a plurality of arc-shaped blocking pieces 51, a mounting plate 52, a driving plate 53 and a driving gear 54. A through hole is provided in the middle of the mounting plate 52 and the driving plate 53, wherein the through hole is arranged in alignment with the light passing hole 101.

The mounting plate 52 is disposed between the substrate 10 and the light-emitting sheet 20. One end of each of the arc-shaped flaps 51 is fixed to the driving plate 53, and two adjacent arc-shaped flaps 51 are previously partially overlapped between the mounting plate 52 and the driving plate 53. The inner arc edges of the arc-shaped blocking pieces 51 are arranged towards the light through hole 101. The fixing points of the plurality of arc-shaped stoppers 51 to the driving plate 53 are arranged at arc bisecting points of the same circle. The driving plate 53 is rotatably mounted to the mounting plate 52. The periphery of the driving plate 53 is integrally extended transversely to form an arc-shaped tooth edge 55. The arcuate tooth edge 55 of the driving disk 53 is engaged with the driving gear 54. Thus, when the driving gear 54 is driven to rotate, the driving disk 53 is driven to rotate. The rotating driving disk 53 can correspondingly drive one end of the arc-shaped baffle 51 to move. Accordingly, the other end of the arc-shaped blocking piece 51 will synchronously slide towards the light-passing hole 101, so that the size of the light-passing hole 101 is adjusted.

Preferably, a plurality of strip-shaped guide grooves 521 are formed on the mounting plate 52, wherein the extending direction of each strip-shaped guide groove 521 is set to pass through the center of the light passing hole 101. The other end of each arc-shaped blocking piece 51 is slidably disposed on the mounting disc 52 along the strip-shaped guide groove 521, so that when the arc-shaped blocking piece 51 is driven, the other end of the arc-shaped blocking piece 51 can be limited to slide within a predetermined range, and further, the size of the light-passing hole 101 is adjusted within the predetermined range.

It should be noted that, when the light hole 101 is implemented in a circular shape, the diameter of the circular light hole 101 can be adjusted to be larger or smaller by the window folding and unfolding mechanism 50 while maintaining the circular shape. That is, the window folding/unfolding mechanism 50 can maintain the original shape of the light transmitting hole 101, and adjust the size of the light transmitting hole 101.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention.
