Description

Technical Field

[0001] This application belongs to the field of infrared optical technology, specifically relating to an imaging device. Background Technology

[0002] In imaging equipment, to achieve the best results according to the theoretical design values ​​for optical imaging, optical engineers typically aim for high parallelism between the optical axis of the optical lens and the optical axis of the imaging target surface. Because uncooled detectors are relatively small, and because high precision is required for the optical axes of the lens and target surface to achieve optimal imaging results, current imaging equipment designs often employ rigid metal laminates to control dimensional accuracy and ensure the parallelism of the two target surfaces. However, relying entirely on rigid metal materials to control dimensional accuracy results in a heavier imaging device. Utility Model Content

[0003] The technical problem to be solved by this application is that the existing imaging devices use rigid metal materials to control dimensional accuracy, resulting in a large weight. In order to solve this technical problem, a lighter imaging device is provided.

[0004] The technical solution proposed in this application is as follows: An imaging device, comprising: case; The first mounting bracket is installed inside the housing; The second mounting bracket and a plurality of locking elements are arranged circumferentially, and one end of each locking element passes through the second mounting bracket and the housing and is connected to the first mounting bracket to press the second mounting bracket and the housing against the first mounting bracket. The locking elements can adjust the pressure between the first mounting bracket, the housing and the second mounting bracket. The housing is made of plastic, while the first and second mounting brackets are made of metal.

[0005] Using the aforementioned imaging device, the detector is mounted on a first mounting bracket, the lens is mounted on a second mounting bracket, and a plastic housing is positioned between the first and second mounting brackets. Multiple locking components spaced circumferentially can adjust the pressure between the first mounting bracket, the housing, and the second mounting bracket, thereby adjusting the coaxiality between the lens and the detector to ensure that the coaxiality of the lens and the detector meets the requirements. Furthermore, the housing is made of plastic, which, compared to metal, effectively reduces weight, making it convenient for handheld use.

[0006] Furthermore, it also includes a fastening layer disposed between the locking member and the first mounting bracket, the housing, and the second mounting bracket to fix the first mounting bracket, the housing, and the second mounting bracket.

[0007] Furthermore, the fastening layer is a fastening adhesive.

[0008] Furthermore, it also includes a lens, which is mounted on the second mounting bracket, and a plurality of the locking members are arranged at intervals around the lens in a circumferential direction.

[0009] Furthermore, it also includes a detector, which is mounted on the first mounting bracket.

[0010] Furthermore, the angle between the focal plane of the lens and the focal plane of the detector does not exceed 0.3°.

[0011] Furthermore, the lens is detachably connected to the second mounting bracket.

[0012] Furthermore, the second mounting bracket has a plurality of connecting protrusions on the side facing the first mounting bracket. The connecting protrusions extend toward the first mounting bracket and pass through the housing. Each of the locking elements passes through the corresponding connecting protrusion and is connected to the first mounting bracket.

[0013] Furthermore, the number of locking components is four.

[0014] Furthermore, it also includes a connector that connects the second mounting bracket and the housing to connect the second mounting bracket to the outside of the housing.

[0015] In summary, the imaging device provided in the above embodiments has at least one of the following advantages: 1. The casing is made of plastic, which effectively reduces the weight of the imaging device and makes it easy to hold and use. 2. A connecting protrusion is formed on the second mounting bracket. The locking member passes through the connecting protrusion and is connected to the first mounting bracket, which can facilitate the adjustment of the angle of the lens on the second mounting bracket and shorten the adjustment time. 3. After the locking mechanism is adjusted, the first mounting bracket, housing, and second mounting bracket are fixed by the fastening layer to prevent the lens angle from shifting during subsequent use, thereby improving the reliability of use and extending the service life.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] To facilitate understanding of the technical solution of this application, the structure of existing molding equipment is described below: In existing imaging equipment, the detector is typically located inside the housing, while the lens is connected to the outside of the housing via a connector. Since components made of metal are generally rigid and have high dimensional accuracy, to improve parallelism, the connecting parts between the detector and the housing, the housing itself, and the connecting parts between the lens and the housing are all made of metal. Thus, most of the imaging equipment's structure is made of metal, resulting in a significant weight. For handheld imaging equipment, this weight severely impacts the user experience.

[0026] To address the aforementioned technical problems, this application provides an imaging device that, while ensuring the coaxiality of the lens and detector optical axes meets the requirements, reduces the weight of the imaging device, thereby facilitating handheld use and optimizing the user experience.

[0027] like Figures 1 to 3 As shown, one embodiment of this application provides an imaging device, including a housing 110, a first mounting bracket 120, a second mounting bracket 130, and a plurality of locking members 140.

[0028] The first mounting bracket 120 is installed inside the housing 110 for mounting the detector 150. Multiple locking members 140 are arranged circumferentially, with one end of each locking member 140 passing through the second mounting bracket 130 and the housing 110, and connected to the first mounting bracket 120 to press the second mounting bracket 130 and the housing 110 against the first mounting bracket 120. The locking members 140 can adjust the pressure between the first mounting bracket 120, the housing 110, and the second mounting bracket 130. The second mounting bracket 130 is used to mount the lens 160. The housing 110 is made of plastic, while the first mounting bracket 120 and the second mounting bracket 130 are made of metal. Specifically, the housing 110 can be made of PEEK or PC, and the first mounting bracket 120 and the second mounting bracket 130 can be made of aluminum alloy or stainless steel. Of course, the housing 110 may also be made of other suitable plastics, and the first mounting bracket 120 and the second mounting bracket 130 may also be made of other suitable metals. The specific materials for plastics and metals are well known to those skilled in the art and are not limited herein.

[0029] Using the aforementioned imaging device, detector 150 is mounted on first mounting bracket 120, lens 160 is mounted on second mounting bracket 130, and plastic housing 110 is located between first mounting bracket 120 and second mounting bracket 130. Multiple locking elements 140 arranged circumferentially can adjust the pressure between first mounting bracket 120, housing 110, and second mounting bracket 130, thereby adjusting the coaxiality between lens 160 and detector 150 to ensure that the coaxiality of lens 160 and detector 150 meets the requirements. Furthermore, the housing 110 is made of plastic, which effectively reduces weight compared to metal, making it convenient for handheld use.

[0030] As described above, it can be determined that in practical applications, the imaging device also includes a detector 150 and a lens 160. The detector 150 is mounted on the first mounting bracket 120, and the lens 160 is mounted on the second mounting bracket 130, and is typically detachably connected to the second mounting bracket 130 via a connector. A plurality of locking members 140 are arranged circumferentially around the lens 160 at intervals to adjust the focal plane of the lens 160. Preferably, after the imaging device is adjusted, the angle between the focal plane of the lens 160 and the focal plane of the detector 150 does not exceed 0.3°.

[0031] It should be explained that the housing 110 is made of plastic and is located between the first mounting bracket 120 and the second mounting bracket 130. The plastic housing 110 has a certain degree of elasticity and is prone to warping. If only the second mounting bracket 130 is connected to the housing 110, warping of the housing 110 will result in an excessively large angle between the focal plane of the lens 160 and the focal plane of the detector 150, meaning that the coaxiality between the optical axis of the lens 160 and the optical axis of the detector 150 is too low. In this application, the second mounting bracket 130 and the housing 110 are pressed onto the first mounting bracket 120 by the locking member 140. The pressure between the second mounting bracket 130, the housing 110 and the first mounting bracket 120 can be adjusted by the locking member 140. Combined with the elasticity of the housing 110 and the multiple locking members 140 arranged circumferentially, the tilt angle of the lens 160 on the second mounting bracket 130 can be adjusted by adjusting the pressure between the second mounting bracket 130, the housing 110 and the first mounting bracket 120 by the locking member 140. That is, the angle between the focal plane of the lens 160 and the focal plane of the detector 150 can be adjusted until the angle between the two focal planes does not exceed 0.3°.

[0032] Furthermore, if the first mounting bracket 120 and the second mounting bracket 130 are directly connected, the connection point between them is also arranged around the lens 160. In this case, the housing 110 cannot enter between the first mounting bracket 120 and the second mounting bracket. However, there is a certain gap between the lens 160 and the detector 150, which makes it inconvenient to set up a waterproof structure between the lens 160 and the detector 150, resulting in poor waterproof performance of the imaging device. In this application, the first mounting bracket 120 is set inside the housing 110, and the second mounting bracket 130 is set outside the housing 110. The housing 110 can extend between the first mounting bracket 120 and the second mounting bracket 130, and can fill the gap between the lens 160 and the detector 150 to a certain extent, thereby facilitating the arrangement of a waterproof structure on the housing 110 and improving the waterproof performance of the imaging device.

[0033] In one embodiment, the locking element 140 is a screw, one end of which passes through the second mounting bracket 130 and the housing 110, and is threadedly connected to the first mounting bracket 120. In practical applications, such as... Figure 3 As shown, there are 4 locking components 140.

[0034] like Figure 2 As shown, in one embodiment, the second mounting bracket 130 has a plurality of connecting protrusions 131 formed on the side facing the first mounting bracket 120. The plurality of connecting protrusions 131 are arranged at intervals around the lens 160 in a circumferential direction, and the connecting protrusions 131 extend toward the first mounting bracket 120 and pass through the housing 110. Each locking member 140 passes through the corresponding connecting protrusion 131 and is connected to the first mounting bracket 120.

[0035] It should be explained that if the second mounting bracket 130 is completely located outside the housing 110, due to the significant warping of the housing 110 (relative to the precision requirements), if the angle of the lens 160 is adjusted solely by the locking element 140 to compensate for the warping of the housing 110, the adjustment range will be too large, resulting in a longer adjustment time and affecting the efficiency of the adjustment. Figure 3 In the illustrated embodiment, by forming a connecting protrusion 131 that passes through the housing 110, the locking member 140 can be initially tightened so that the connecting protrusion 131 abuts against the first mounting bracket 120. Then, by gradually loosening the locking member 140, the housing 110, due to its elastic deformation tendency, will cause the second mounting bracket 130 and the lens 160 to adjust their angles. It can be determined that when the multiple connecting protrusions 131 abut against the first mounting bracket 120, the coaxiality between the optical axis of the lens 160 and the optical axis of the detector 150 is already relatively high. Then, the locking member 140 further adjusts the coaxiality between the two. In this way, the coaxiality between the optical axis of the lens 160 and the optical axis of the detector 150 can be further improved.

[0036] In one embodiment, the imaging device further includes a fastening layer disposed between the locking member 140 and the first mounting bracket 120, the housing 110, and the second mounting bracket 130 to secure the first mounting bracket 120, the housing 110, and the second mounting bracket 130. It should be noted that after the lens angle 160 is adjusted, the lens angle may still change over long-term use due to the tendency of the housing 110 to deform. Therefore, after adjustment, the fastening layer secures the first mounting bracket 120, the housing 110, and the second mounting bracket 130. In practical applications, the fastener is adhesive, which can be applied by dispensing between the locking member 140 and the first mounting bracket 120, the housing 110, and the second mounting bracket 130 to secure them.

[0037] Please see Figure 3 In one embodiment, the imaging device further includes a connector 170. The connector 170 is connected to the second mounting bracket 130 and the housing 110 to connect the second mounting bracket 130 to the housing 110. In practical applications, there are multiple connectors 170, and the connectors 170 are screws.

[0038] In summary, the imaging device provided in the above embodiments has at least one of the following advantages: 1. The housing 110 is made of plastic, which can effectively reduce the weight of the imaging device and make it easy to use handheld; 2. A connecting protrusion 131 is formed on the second mounting bracket 130. The locking member 140 passes through the connecting protrusion 131 and is connected to the first mounting bracket 120, which can facilitate the adjustment of the angle of the lens 160 on the second mounting bracket 130 and shorten the adjustment time. 3. After the locking component 140 is adjusted, the first mounting bracket 120, the housing 110 and the second mounting bracket 130 are fixed by the fastening layer to prevent the lens 160 from shifting during subsequent use, thereby improving the reliability of use and extending the service life.
