In the infrared product, the shutter device is used for carrying out image correction, the shutter device comprises a window and a blade, and when the blade shields the window, the image correction can be carried out; when the blade leaves the window, the optical emergent light path can pass through, so that imaging is facilitated.

In the shutter devices in the prior art, a planarization design is adopted, that is, the blades are moved in a plane parallel to the window, for example, the blades are rotated around a rotating shaft perpendicular to the plane of the window, or the blades are pushed and pulled along the plane parallel to the window, so that the positions of the blades are switched, and the blades block or leave the window.

However, this design, no matter how extremely designed in the plane, needs to leave enough accommodation space for the blade to give way to the window, which inevitably limits the window size, and at the same time, makes the structural size of the window in the plane direction larger. With the development of infrared technology, infrared products gradually permeate into the fields of consumer electronics, automobile auxiliary driving, intelligent home and the like, and the window size of the shutter device is limited by the window size ratio and the structural size of the window in the plane direction, so that the application and popularization of the infrared products in the fields are limited to a great extent.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The core of the utility model is to provide a shutter device, wherein the size of a window 11 is high, and the structural size of the window 11 in the plane direction is small. Another core of the present utility model is to provide an infrared device including the above shutter device, in which the window 11 of the shutter device has a high ratio in size and the window 11 has a small structural size in the plane direction.

Referring to fig. 1 and 2, an embodiment of the present utility model provides a shutter device, which includes a body 1, a shielding member 2 and a driving member 3, wherein the body 1 mainly plays a bearing role, and the body 1 is provided with a window 11; the shielding member 2 is rotatably arranged on the body 1, and the rotating shaft of the shielding member 2 is parallel to the plane of the window 11; the driving member 3 is disposed on the main body 1, and is used for driving the shielding member 2 to rotate, so that the shielding member 2 shields or leaves the window 11.

In operation, the shutter 2 is driven to rotate by the driving member 3, so that the shutter 2 shields the window 11 (shown in fig. 1) to correct an image; by driving the shutter 2 in rotation by the driving member 3, the shutter 2 is allowed to open the window 11 (as shown in fig. 2), and the optical outgoing light path can be made to pass through the window 11 for imaging.

Because the rotating shaft of the shielding member 2 is parallel to the plane where the window 11 is located, when the driving member 3 drives the shielding member 2 to rotate, the shielding member 2 is turned over far from or near to the plane where the window 11 is located, so that the shielding member 2 rotates into the space perpendicular to the plane direction where the window 11 is located, the shielding member 2 leaving the window 11 can be accommodated by utilizing the space perpendicular to the plane direction where the window 11 is located, the space where the window 11 is located is prevented from being occupied when the shielding member 2 leaving the window 11, namely, the shutter device provided by the embodiment of the utility model overcomes the technical prejudice of optimizing the blade position in the plane space where the window 11 is located in the prior art, breaks through the design concept of blade movement planarization, reasonably utilizes the space perpendicular to the plane direction where the window 11 is located, effectively reduces the structural dimension of the window 11 of the shutter device, is beneficial to improving the dimension ratio of the window 11 of the shutter device, and the dimension of the window 11 is larger; in addition, the limitation of the larger structural size of the shutter device in the plane direction of the window 11 on the application and popularization of infrared products is avoided, the application field of the shutter device is expanded, and the universality of the shutter device is improved.

It should be noted that, the shielding member 2 may be an integral structural member, for example, a single-blade structure, or may be a plurality of split structural members, where the plurality of split structural members jointly form the shielding member 2, and when the shielding member 2 shields the window 11, the plurality of split structural members are spliced together to jointly shield the window 11, which is equivalent to a multi-blade structure.

Considering the simplicity of construction in combination with the avoidance of excessive occupation of space of the shutter 2 perpendicular to the plane of the window 11 when opening the window 11, in some embodiments, the shutter 2 comprises a first shutter 21 for shielding a portion of the window 11 and a second shutter 22 for shielding the remainder of the window 11, in conjunction with fig. 1-4. That is, the present embodiment divides the shutter 2 into the first shutter 21 and the second shutter 22, and shields the window 11 by the combined action of the first shutter 21 and the second shutter 22, that is, the sum of the areas of the first shutter 21 and the second shutter 22 is greater than or equal to the area of the window 11. In addition, compared with the single shielding member 2, when the first shielding member 21 and the second shielding member 22 rotate around the rotation shafts thereof, the first shielding member 21 and the second shielding member 22 have at least partial overlapping dimensions in the direction perpendicular to the plane of the window 11, so that the space occupied in the direction perpendicular to the plane of the window 11 can be reduced, and the structural dimension perpendicular to the plane of the window 11 can be reduced. Furthermore, the structure in which the shielding member 2 includes the first shielding member 21 and the second shielding member 22 has fewer assembly parts and a simple structure than the structure in which the shielding member 2 is divided into a plurality of structural members.

Further, in order to prevent light leakage when the first and second shutters 21 and 22 block the window 11, please refer to fig. 7 and 8, in some embodiments, when the first and second shutters 21 and 22 each block the window 11, an end of the first and second shutters 21 and 22 away from the respective rotation axes has an overlap. For convenience of description, the rotation axis corresponding to the first shutter 21 is defined as a first rotation axis 211, and the rotation axis corresponding to the second shutter 22 is defined as a second rotation axis 221, that is, when the first shutter 21 and the second shutter 22 each block the window 11, an end of the first shutter 21 away from the first rotation axis 211 overlaps an end of the second shutter 22 away from the second rotation axis 221.

That is, the junction of the first and second shutters 21 and 22 has an overlapping portion, which prevents the junction of the first and second shutters 21 and 22 from generating a gap, resulting in light leakage, thereby ensuring that the first and second shutters 21 and 22 are completely closed to completely block the window 11. For example, as shown in fig. 7 and 8, defining a distance L1 from an end of the first shutter 21 away from the first rotation axis 211 to the first rotation axis 211 and a distance L2 from an end of the second shutter 22 away from the second rotation axis 221 to the second rotation axis 221, when both the first shutter 21 and the second shutter 22 block the window 11, L1 and L2 have an overlapping length of the distance L.

In addition, in order to enhance the overlapping effect of the first shielding member 21 and the second shielding member 22 away from the end of the respective rotating shafts, please continue to refer to fig. 7 and 8, in some embodiments, one of the end of the first shielding member 21 away from the first rotating shaft 211 and the end of the second shielding member 22 away from the second rotating shaft 221 is provided with a bending portion 212, and the other overlaps with the bending portion 212 to form an overlapping. That is, the present embodiment ensures that the first and second shutters 21 and 22 have a sufficient overlapping area by providing the bent portion 212 and overlapping the first and second shutters 21 and 22 by the bent portion 212, thereby ensuring a light shielding effect at the junction of the first and second shutters 21 and 22.

The bending portion 212 may be provided on the first shield 21 or the second shield 22; when the bending part 212 is arranged on the first shielding piece 21, the bending part 212 is overlapped with one end of the second shielding piece 22 far away from the second rotating shaft 221; when the bending portion 212 is disposed on the second shielding member 22, the bending portion 212 overlaps an end of the first shielding member 21 away from the first rotating shaft 211.

In addition, the bending direction of the bending portion 212 is not limited in this embodiment, and the bending portion 212 may overlap one side of the first shielding member 21 or the second shielding member 22 facing away from the window 11 (as shown in fig. 7 and 8); the bending portion 212 may overlap one side of the first shielding member 21 or the second shielding member 22 facing the window 11.

In addition, the above embodiments do not limit the rotation direction of the first shutter 21 and the second shutter 22, and please continue to refer to fig. 1 and 2, and in some embodiments, the first rotation shaft 211 and the second rotation shaft 221 are disposed in parallel. This makes the first shielding member 21 and the second shielding member 22 set relatively, and both are in the form of double door structure, so that the rotation directions of the first shielding member 21 and the second shielding member 22 are the same or opposite, and an included angle is avoided between the rotation directions of the first shielding member 21 and the second shielding member 22, which is convenient for structural layout.

In addition, as shown in fig. 5 and 6, in some embodiments, the body 1 is connected with a cover plate 4. It can be understood that after the installation of the parts inside the body 1 is completed, the cover plate 4 is connected with the body 1, so that the assembly is convenient.

Further, referring to fig. 9 and 10, in some embodiments, when the first shutter 21 and the second shutter 22 are both away from the window 11, a distance H1 from an end of the first shutter 21 away from the first rotation axis 211 to the cover plate 4 is equal to a distance H2 from an end of the second shutter 22 away from the second rotation axis 221 to the cover plate 4. That is, when the first shielding member 21 and the second shielding member 22 both allow the window 11 to be opened, the heights of the two are the same in the direction perpendicular to the plane of the window 11, and there is no difference in height. It will be appreciated that, in order to avoid interference, the height of the cover plate 4 in the direction perpendicular to the plane of the window 11 is determined by the maximum heights of the first and second shutters 21 and 22 in the direction perpendicular to the plane of the window 11, so that the distances from the end of the first and second shutters 21 and 22 away from the respective rotation axes to the cover plate 4 are equal, which is beneficial to ensuring that the cover plate 4 has a suitable height in the direction perpendicular to the plane of the window 11, so as to reasonably utilize the space in the direction perpendicular to the plane of the window 11 and minimize the structural size of the shutter device in the direction perpendicular to the plane of the window 11.

To ensure that the end of the first shutter 21 and the second shutter 22 remote from the respective axes of rotation are equidistant from the cover plate 4, please continue to refer to fig. 9 and 10, in some embodiments, the first axis of rotation 211 and the second axis of rotation 221 are disposed in the same plane, and the end of the first shutter 21 remote from the first axis of rotation 211 is equidistant from the first axis of rotation 211 and the end of the second shutter 22 remote from the second axis of rotation 221 is equidistant from the second axis of rotation 221. For example, defining a distance L1 from an end of the first shutter 21 away from the first rotation axis 211 to the first rotation axis 211, and a distance L2 from an end of the second shutter 22 away from the second rotation axis 221 to the second rotation axis 221, l1=l2. That is, the present embodiment ensures that when the first shutter 21 and the second shutter 22 are both clear of the window 11 by making the distance from the free end of the first shutter 21 to the rotation axis end thereof equal to the distance from the free end of the second shutter 22 to the rotation axis end thereof and making the first rotation axis 211 and the second rotation axis 221 to be installed in the same plane, the distances from the ends of the first shutter 21 and the second shutter 22 away from the respective rotation axes to the cover plate 4 are equal, facilitating the processing of the first shutter 21 and the second shutter 22, and at the same time, facilitating the assembly of the shutter device.

It should be noted that, in the above embodiments, the specific arrangement of the driving member 3 is not limited, and referring to fig. 3 and 4, in some embodiments, the driving member 3 includes a first driving member 31 and a second driving member 32, and the first driving member 31 is connected to the first shielding member 21 for driving the first shielding member 21 to rotate; the second driving member 32 is connected to the second shielding member 22 for driving the second shielding member 22 to rotate. That is, in this embodiment, the first driving member 31 and the second driving member 32 are adopted to independently drive the first shielding member 21 and the second shielding member 22 to rotate, so that the structure is convenient to set up, and the first driving member 31 and the second driving member 32 are convenient to control, respectively, for example, when one ends of the first shielding member 21 and the second shielding member 22 away from the respective rotation axes have overlapping when shielding the window 11, the rotation of the first shielding member 21 and the second shielding member 22 is convenient to have a timing difference so as to avoid interference when both the first shielding member 21 and the second shielding member 22 rotate toward the window 11.

Of course, in other embodiments, the same driving member 3 may be used to rotate the first shielding member 21 and the second shielding member 22 through a transmission device.

It should be noted that, the specific structure of the first driving member 31 and the second driving member 32 is not limited in the above embodiment, as long as the first driving member 31 and the second driving member 32 can respectively drive the first shielding member 21 and the second shielding member 22 to rotate.

With continued reference to fig. 3 and 4, in some embodiments, at least one of the first and second drivers 31, 32 comprises: a rotation driving mechanism 311, a decelerator 312, a driving gear 313 and a driven gear 314, the rotation driving mechanism 311 for outputting rotation power; the decelerator 312 is connected with the rotation driving mechanism 311; the driving gear 313 is connected with the decelerator 312; the driven gear 314 is engaged with the driving gear 313 and is connected to the rotation shaft of the first shutter 21 or the second shutter 22. In operation, the rotation driving mechanism 311 outputs rotation power to drive the speed reducer 312 to move, the speed reducer 312 is used to reduce the speed to drive the driving gear 313 to rotate, the driving gear 313 drives the driven gear 314 to rotate, and the driven gear 314 drives the rotating shaft of the first shielding member 21 or the second shielding member 22 to rotate, so that the rotation of the first shielding member 21 or the second shielding member 22 is realized.

It will be appreciated that the rotary drive mechanism 311 may output either a forward or reverse rotary power to enable the first shutter 21 or the second shutter 22 to be rotated in a direction toward or away from the window 11. In some embodiments, the rotary drive mechanism 311 is a motor.

In addition, in view of the simplicity of construction, in some embodiments, the drive gear 313 and the driven gear 314 are identical in modulus, size, and model.

Of course, in other embodiments, the driving member 3 may be other structures, for example, the driving member 3 is a solenoid valve cooperating with a structure to limit the rotation of the shielding member 2, so long as the driving member 3 can drive the shielding member 2 to rotate.

In addition to the shutter device, the present utility model further provides an infrared device including the shutter device disclosed in the foregoing embodiment, and the structure of each other portion of the infrared device is referred to the prior art, which is not repeated herein.

The key point of this embodiment is that, with the shutter device disclosed in any one of the above embodiments, since the size of the window 11 of the shutter device is large in the ratio, and the structural size of the window 11 in the plane direction is small, it is beneficial to miniaturize the structure of the infrared device along the plane of the window 11, and expand the application scenario of the infrared device.
