The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, an embodiment of the present invention discloses a shutter structure that can be applied to a camera, the shutter structure including a shutter body 100, a soaking member, and a shutter blade 300.
The shutter body 100 is provided with a light inlet 110, and light outside the shutter structure can be incident into the shutter structure through the light inlet 110 without being blocked by other structures such as the shutter blade 300, so as to form an image. The size and shape of the light inlet 110 can be determined according to practical requirements, and are not limited herein. Specifically, the shutter body 100 may include at least two parts, which may include an upper part and a lower part, and the shutter blade 300 is interposed between the upper part and the lower part, and the shutter blade 300 may be switched between a state of shielding the light entrance hole 110 and a state of avoiding the light entrance hole 110 by being driven by the driving mechanism. Specifically, one of the upper and lower portions of the shutter body 100 may be made of a metal material to improve the overall structural strength of the shutter body 100; in another embodiment of the present application, the whole shutter body 100 is a plastic structural member, in which case, the insulating performance of the shutter body 100 can be better, and the heat conduction efficiency inside the shutter body 100 can be reduced to a certain extent, so that the heat can be transferred to the soaking member as much as possible.
The soaking piece can be made of metal and other materials with better heat-conducting property, so that the soaking piece has the capability of uniform heat. The soaking piece is attached to the surface of the shutter body 100, and specifically, the soaking piece can be fixed on the shutter body 100 through connecting pieces such as clamping pieces, screws or rivets, and the soaking piece and the surface of the shutter body 100 are attached to each other, so that the temperatures of different positions on the shutter body 100 can be ensured to be basically the same as far as possible under the relatively good heat conduction effect of the soaking piece. Specifically, the shape of the soaking member may be similar to the shape of the shutter body 100, and the soaking member may be wrapped outside the outer surface of the shutter body 100, so as to ensure that the heat at any position on the soaking member may be diffused to the entire shutter body 100 through the soaking member, thereby making the temperature at each position on the shutter body 100 substantially the same. Of course, it should be noted that, in the process of covering the shutter body 100 with the heat spreader, the heat spreader needs to be avoided from the light inlet 110, so as to ensure that light outside the shutter body 100 can enter the shutter body 100 through the light inlet 110.
The number of the shutter blades 300 may be determined according to a specific shape of the shutter blade 300 to block the light inlet 110 of the shutter body 100 by at least one shutter blade 300. The shutter blade 300 is movably connected to the shutter body 100, so that the shutter blade 300 can block or avoid external light from entering the shutter structure through the light inlet 110 by moving the shutter blade 300 relative to the shutter body 100 during the operation of the shutter structure. Specifically, the shutter blade 300 may be formed of a material having a relatively high structural strength, such as plastic, so as to ensure that the shutter still maintains a relatively high structural integrity during frequent movement, thereby prolonging the service life thereof. In another embodiment of the present application, the shutter blade 300 may be a metal structure, that is, the shutter blade 300 is made of a metal material, which can ensure a high structural strength of the shutter blade 300 and a high thermal conduction efficiency of the shutter blade 300. In order to further prolong the service life of the shutter blade 300, the shutter blade 300 may be a stainless steel structure, that is, the shutter blade 300 is made of stainless steel, so that the shutter blade 300 has high structural strength and heat conduction efficiency, and meanwhile, the shutter structure can be prevented from being rusted due to the fact that the shutter structure works in a relatively humid environment.
As described above, the shutter blade 300 can be driven to move relative to the shutter body 100 by a driving device, and specifically, the shutter blade 300 can be provided with the driving hole 310 and the installation hole 320, wherein the driving device can be in transmission connection with the shutter blade 300 through the driving hole 310, and the shutter blade 300 is rotatably installed on the shutter body 100 through the installation hole 320, so that the shutter blade 300 can rotate relative to the shutter body 100 around the installation hole 320, and the purpose of shielding the light inlet 110 and avoiding the light inlet 110 is achieved. More specifically, the mounting hole 320 may be a circular hole to ensure that the rotational coupling stability between the shutter blade 300 and the shutter body 100 is relatively high; the driving hole 310 may be a kidney-shaped hole, and a driving mechanism may be stably installed in the kidney-shaped hole to drive the shutter blade 300 to rotate about an axis of the installation hole 320.
The embodiment of the application provides a shutter structure, it includes shutter body 100, soaking piece and shutter blade 300, shutter blade 300 swing joint is on shutter body 100, the heat that shutter blade 300 work produced can be transmitted to on shutter body 100, soaking piece is attached on the surface of shutter body 100, the heat of different positions department can be through soaking piece interdiffusion on the shutter body 100, make the temperature of each position department on shutter body 100 the same basically, thereby when demarcating the temperature through shutter body 100 in the imaging process, can promote the homogeneity that the temperature was markd, and then promote the imaging quality of camera.
Alternatively, the soaking member includes the first soaking sheet 210, the first soaking sheet 210 may be made of a material with better thermal conductivity, such as metal, etc., and parameters, such as the thickness and the shape of the first soaking sheet 210, may be determined according to practical situations, which are not limited herein. The first soaking plate 210 is provided with a first avoiding hole 211, the first avoiding hole 211 is a hole-shaped structure penetrating through the first soaking plate 210, and the first avoiding hole 211 is made to avoid the light inlet hole 110 in a state that the first soaking plate 210 and the shutter body 100 are assembled with each other, so that light outside the shutter structure can enter the shutter structure through the first avoiding hole 211 and the light inlet hole 110. Specifically, the shape of the first avoiding hole 211 may be the same as that of the light inlet hole 110, or may be different from that of the light inlet hole 110, and it is only necessary to ensure that the first avoiding hole 211 can avoid the light inlet hole 110.
The first soaking plate 210 is attached to the first surface of the shutter body 100 facing the light incident side, and specifically, the first soaking plate 210 may be fixed to the shutter body 100 by a connector such as a clip, a screw, or a rivet, and the first soaking plate 210 is attached to the first surface of the shutter body 100, so that the temperatures of different positions on the shutter body 100 are substantially the same under the better heat conduction effect of the first soaking plate 210.
Under the condition of adopting the technical scheme, the attaching area between the first soaking piece 210 and the shutter body 100 is relatively large, so that a good soaking effect can be provided for the shutter body 100 by means of the first soaking piece 210, and the temperature consistency of all positions on the shutter body 100 is relatively high; meanwhile, even though the overall size of the shutter body 100 is small, the area of the first surface facing the light incident side in the shutter body 100 is relatively large, so that the assembly difficulty between the first soaking plate 210 and the shutter body 100 is relatively small, and the processing and production of the shutter structure are facilitated.
Optionally, the soaking part further includes a second soaking plate 220, and the second soaking plate 220 may be attached to a side of the shutter body 100 away from the first soaking plate 210, so that the first soaking plate 210 and the second soaking plate 220 cooperate to provide a soaking effect for the shutter body 100, thereby further improving the temperature uniformity at each position on the shutter body 100. Specifically, the second soaking plate 220 may also be supported by a material with relatively good thermal conductivity, such as metal, etc., the shape and size of the second soaking plate 220 may also be determined according to the shutter body 100, and the second soaking plate 220 and the shutter body 100 may also be fixed to each other by means of clamping or connecting pieces, etc., and a good bonding effect between the second soaking plate 220 and the shutter body 100 is ensured. Of course, in the process of disposing the second soaking plate 220, the second soaking plate 220 also needs to be avoided from the light inlet 110, specifically, the second soaking plate 220 is disposed with a second avoiding hole 221, and in the state that the second soaking plate 220 and the shutter body 100 are assembled with each other, the second avoiding hole 221 is avoided from the light inlet 110, so as to ensure that light outside the shutter structure can normally enter the shutter structure through the light inlet 110.
Further, the side of the shutter body 100 facing away from the first surface is provided with a mounting sinking groove 120, and the depth of the mounting sinking groove 120 can be determined according to the actual situation such as the mounting position of the shutter blade 300, and is not limited herein. As described above, the shutter structure can be applied to a camera, and the camera includes other structural members besides the shutter structure, such as a lens assembly and a photosensitive chip, of course, when the camera is an infrared camera, the camera can also include devices such as an infrared detector, and a part of the devices such as the infrared detector can extend into the mounting sinking groove 120 from one side of the shutter body 100 departing from the light incident side, thereby reducing the size of the whole camera in the axial direction of the light incident hole 110, further making the whole size of the camera relatively smaller, reducing the mounting space occupied by the camera, and improving the product competitiveness.
In the case that the installation sinking groove 120 is formed in the shutter body 100, the second soaking plate 220 may be attached to the bottom of the installation sinking groove 120, such that the second soaking plate 220 is disposed adjacent to the periphery of the light inlet 110, thereby greatly improving the temperature uniformity of the adjacent portion of the shutter body 100 around the light inlet 110. In addition, as described above, the shutter body 100 may include upper and lower parts between which the shutter blade 300 may be interposed, and by mounting the second soaking plate 220 at the bottom of the groove where the sinking groove 120 is installed in the shutter body 100, the second soaking plate 220 may be brought closer to the shutter blade 300, thereby further improving the efficiency and uniformity of the conduction of heat to the shutter blade 300 by the second soaking plate 220.
In addition, in order to further improve the uniformity of the temperature at various positions on the shutter body 100, a third soaking plate, a fourth soaking plate, and the like may be attached to the side surfaces and the like of the shutter body 100, and the first soaking plate 210, the second soaking plate 220, the third soaking plate, and the fourth soaking plate may be connected to each other, so that the heat can be transmitted between the soaking plates, and the uniformity of the temperature at various positions on the shutter body 100 can be further improved.
Alternatively, the projection of the first soaking piece 210 along the axial direction of the light inlet hole 110 coincides with the first surface, that is, the first surface is entirely covered with the first soaking piece 210, and the shape of the first soaking piece 210 is the same as that of the first surface. In this case, while ensuring that the difficulty of mounting the first soaking sheet 210 is small, the coverage area of the first soaking sheet 210 on the shutter body 100 can be maximally lifted. Specifically, the outer shape of the first soaking sheet 210 may be made the same as that of the shutter body 100, and the shape and size of the first escape hole 211 may be made correspondingly the same as those of the light entrance hole 110. It should be noted that, in the actual production process, the technical solution that there is a slight difference between the axial projection of the first soaking plate 210 in the light inlet 110 and the first surface due to the processing error and the like is also within the protection scope of the present application. In addition, in order to ensure that the light entrance hole 110 is not blocked by the first soaking plate 210 during the process of assembling the first soaking plate 210 and the shutter body 100, the size of the first avoiding hole 211 may be slightly larger than the size of the light entrance hole 110 to further reduce the difficulty of assembly, and of course, the size of the first avoiding hole 211 may be equal to the size of the light entrance hole 110 when the assembly accuracy is sufficient.
Correspondingly, the projection of the second soaking plate 220 along the axial direction of the light inlet 110 may coincide with the bottom of the installation sinking groove 120, that is, the bottom of the installation sinking groove 120 is entirely covered with the second soaking plate 220, and the shapes of the second soaking plate 220 and the bottom of the groove are the same. In this case, while ensuring that the difficulty of mounting the second soaking sheet 220 is small, the coverage area of the second soaking sheet 220 on the shutter body 100 can be maximally raised. Specifically, the second soaking plate 220 may have the same shape as the bottom of the groove where the sinking groove 120 is installed, and the second avoiding hole 221 may have the same shape and size as the light entrance hole 110. It should be noted that, in the actual production process, the technical solution that there is a slight difference between the axial projection of the second soaking plate 220 in the light inlet 110 and the second surface due to the factors such as the processing error also falls within the protection scope of the present application. In addition, in order to ensure that the light entrance hole 110 is not blocked by the second soaking plate 220 in the process of assembling the second soaking plate 220 and the shutter body 100, the size of the second avoiding hole 221 may be slightly larger than the size of the light entrance hole 110 to further reduce the difficulty of assembly, and of course, the size of the second avoiding hole 221 may be equal to the size of the light entrance hole 110 when the assembly accuracy is sufficient.
As described above, each of the first heat equalizing sheet 210 and the second heat equalizing sheet 220 may be made of a material having a good thermal conductivity, such as metal, and for example, the first heat equalizing sheet 210 and the second heat equalizing sheet 220 may be formed of metal copper. In another embodiment of the present application, the first soaking plate 210 and/or the second soaking plate 220 are made of graphite, that is, the first soaking plate 210 and/or the second soaking plate 220 are made of graphite material, and the thermal conductivity of graphite is better than that of metal, so as to further improve the temperature uniformity of the shutter body 100. Furthermore, the first soaking plate 210 and the second soaking plate 220 are graphite structural members, and in this case, the heat conducting performance of the first soaking plate 210 and the heat conducting performance of the second soaking plate 220 are relatively good, so that the uniformity of heat distribution on the shutter body 100 can be greatly improved, the calibration uniformity of an image can be improved, and the imaging quality can be further improved.
Further, the thickness of the first soaking plate 210 and/or the second soaking plate 220 can be 0.1-0.2 mm, more specifically, the thickness of the first soaking plate 210 and the thickness of the second soaking plate 220 can be 0.1-0.2 mm, under the condition, the first soaking plate 210 and the second soaking plate 220 can be guaranteed to occupy a relatively small installation space on the premise of having a relatively strong heat conduction performance, the shutter structure and the camera are guaranteed to have a relatively small volume, and the installation space occupied by the shutter structure and the camera is reduced.
As described above, the first soaking plate 210 and/or the second soaking plate 220 may be fixed to the shutter body 100 by a connector, and in another embodiment of the present application, the first soaking plate 210 and/or the second soaking plate 220 are adhesively fixed to the shutter body 100, and more specifically, both the first soaking plate 210 and the second soaking plate 220 are adhesively fixed to the shutter body 100, which may further reduce the difficulty in assembling the first soaking plate 210 and the second soaking plate 220 to the shutter body 100, and may enhance the adhesion effect between the first soaking plate 210 and the second soaking plate 220 and the shutter body 100 to a certain extent, further improve the heat transfer efficiency and the heat transfer effect between the shutter body 100 and the first soaking plate 210 and the second soaking plate 220, and further ensure the temperature uniformity at each position on the shutter body 100. Specifically, the first soaking plate 210 and the second soaking plate 220 may be bonded and fixed to the shutter body 100 by a heat conductive adhesive, or the first soaking plate 210 and the second soaking plate 220 may be bonded and fixed to the shutter body 100 by a double-sided adhesive, which further reduces the difficulty of assembling the shutter structure.
