[0033] Please refer to the following: Figure 1 and Figure 2The modified thermal imaging device provided in one embodiment of this application includes an infrared host 10, a bracket 20 and a display module 30; the infrared host 10 is mounted on an external device 50; one end of the bracket 20 is mounted on the external device 50 and the other end is used to connect to the display module 30.

[0034] The infrared host 10 is the main component that uses infrared imaging technology to collect infrared signals, convert them into image signals, and then process and analyze them to complete the image imaging function. The imaging chip includes an infrared image sensor, which converts the infrared light signals collected by the infrared lens 12 into electrical signals and forms an infrared image.

[0035] The infrared host 10 typically also includes a housing 11, an infrared module, and a laser module, with both the infrared module and the laser module located on the front side of the housing 11. Optionally, the infrared module includes an infrared lens 12, which protrudes from the front of the housing 11 to focus infrared light for imaging. Optionally, the infrared module also includes an imaging chip housed within the housing 11. The housing 11 can protect the imaging chip housed therein, and the housing 11 may have a mounting structure to facilitate mounting to the external device 50. The mounting structure between the housing 11 and the external device 50 can be any known structure, such as a snap-fit ​​structure, a locking structure, a magnetic structure, etc., and this application does not limit this. Optionally, the laser module may include a laser emitter and a laser receiver. The laser module and the infrared lens 12 may be located on the same side of the infrared host 10. The laser module can emit laser light towards the target and receive the laser light reflected back from the target for ranging.

[0036] The bracket 20 is used to mount the display module 30 onto the external device 50. The mounting structure between the bracket 20 and the external device 50 can be any known structure, such as a snap-fit ​​structure, a locking structure, or a magnetic structure. The bracket 20 protrudes forward from the external device 50 and can support the display module 30 protruding from the front of the external device 50.

[0037] In the above embodiments, the retrofit thermal imaging device is specifically designed for retrofitting the external device 50. The infrared host 10 is mounted on the external device 50 using the housing 11, and the display module 30 is mounted on the external device 50 via the bracket 20. The assembly of the infrared host 10 and the display module 30 each forms a modular design, which is convenient for users to retrofit onto the external device 50. The assembly is simple and the stability after assembly can be guaranteed, resulting in high reliability.

[0038] External device 50 can be any object requiring retrofitted infrared imaging capabilities, such as helmets or vehicles. When the retrofitted thermal imaging device is used with a helmet, the infrared host 10 is mounted on the helmet, and the infrared lens 12 faces the front of the helmet wearer to facilitate real-time imaging of the helmet wearer's forward field of view. The display module 30 is mounted on the helmet via a bracket 20, and the infrared images acquired by the infrared host 10 are displayed on the display module 30 for the helmet wearer to observe. In another optional example, the retrofitted thermal imaging device can also be used in a vehicle-assisted driving scenario, with the infrared host 10 mounted at the front of the vehicle and the display module 30 mounted in the driver's cab via a bracket 20. In yet another optional example, the retrofitted thermal imaging device can also be used in a vehicle-mounted hunting scenario, with the infrared host 10 mounted on the roof or front of the vehicle for observing prey, and the display module 30 mounted in the driver's cab via a bracket 20, allowing the user to quickly observe hidden targets directly through the display module 30.

[0039] like Figure 2 As shown, in an optional example, the external device 50 is a helmet, with the infrared host 10 and the bracket 20 mounted on opposite sides of the helmet; the display module 30 protrudes from the bracket 20 in front of the helmet-wearing user's line of sight. In this embodiment, the infrared host 10 and display module 30 of the modified thermal imaging device are mounted on opposite sides of the helmet, allowing for weight balance and ensuring that the lens of the infrared host 10 faces the front of the helmet, thus ensuring a sufficiently complete field of view. The design of the bracket 20 allows the display module 30 to be stably mounted on the helmet and supports positioning the display module 30 at a specified distance in front of the helmet-wearing user's eyes for convenient observation.

[0040] Optionally, the bracket 20 includes a long rod 21 and a rotating connection assembly 23; the rotating connection assembly 23 is used to adjust the display module 30 in the horizontal and / or vertical directions. The length of the long rod 21 is mainly determined by the distance the display module 30 protrudes outward. The rotating connection assembly 23 is provided to support the adjustment of the display module 30 within a certain range. The rotating connection assembly 23 can be located at the position where the long rod 21 connects to the external device 50, or at the position where the long rod 21 connects to the display module 30. The adjustment of the display module 30 can include adjustment in the horizontal direction or adjustment in the vertical direction.

[0041] Please refer to the following: Figures 3 to 5The rotating connection component 23 is located at the end of the long rod 21 that is connected to the display module 30. The rotating connection component 23 includes a column 231, a first rotating shaft 232 and a second rotating shaft 233 connected to the column 231. The first rotating shaft 232 is used to plug into the display module 30 to realize the rotation adjustment of the display module 30 in the horizontal direction, and the second rotating shaft 233 is used to realize the rotation adjustment of the display module 30 in the vertical direction. In this embodiment, the column 231 serves as the main structure of the rotating connection assembly 23. The first rotating shaft 232 and the second rotating shaft 233 are respectively connected to different sides of the column 231. Specifically, the first rotating shaft 232 is perpendicular to the length direction of the column 231 and connected to the front side of the column 231, while the second rotating shaft 233 is parallel to the length direction of the column 231 and connected to the bottom end of the column 231. The first rotating shaft 232 and the second rotating shaft 233 can rotate relative to the column 231 respectively, thereby realizing the rotational adjustment of the display module 30 in different directions. This allows for adjustment of the relative angle between the display module 30 connected to the first rotating shaft 232 and the long rod 21.

[0042] The first rotating shaft 232 is a T-shaped rotating shaft, which includes a plug section 2321, a threaded section 2322 opposite to the plug section 2321, and a fixing plate 2323 surrounding the threaded section 2322. The fixing member passes through the fixing plate 2323 and connects to the column 231 to connect the T-shaped rotating shaft to the column 231. The column 231 has a roughly cylindrical overall shape, with one side of the top part set as a flat mounting surface. A threaded hole is provided on the mounting surface of the top part. The threaded section 2322 of the T-shaped rotating shaft is screwed into the threaded hole. The fixing plate 2323 fits against the mounting surface and has a through hole for the fixing member to pass through the through hole before connecting to the column 231, thereby connecting the T-shaped rotating shaft to the column 231. The plug section 2321 is flat and protrudes from the mounting surface perpendicularly to the column 231. The plug-in section 2321 is provided with a fixing hole. After the plug-in section 2321 is inserted into the display module 30, it can be further locked to the internal structure of the display module 30 through the fixing hole. The T-shaped rotating shaft utilizes the engagement between the threaded section 2322 and the threaded hole on the column 231. The threaded section 2322 can rotate within the threaded hole, thereby adjusting the deflection angle of the display module 30 connected to the plug-in section 2321 in the front-back direction.

[0043] The second rotating shaft 233 includes a first connecting rod 2333 and a second connecting rod 2334. The first connecting rod 2333 includes a connecting section 2331 and a threaded section 2332. The connecting section 2331 is connected to the column 231 by a fastener. The second connecting rod 2334 is sleeved on the threaded section 2332 of the first connecting rod 2333 and extends vertically relative to the first connecting rod 2333. The second connecting rod 2334 is connected to the long rod 21. In this embodiment, the shape and structure of the first connecting rod 2333 are the same as those of the first rotating shaft 232. The second connecting rod 2334 is vertically arranged relative to the first connecting rod 2333 and sleeved on the threaded section 2332 of the first connecting rod 2333. The second connecting rod 2334 can rotate relative to the first connecting rod 2333, thereby adjusting the horizontal deflection angle of the entire column 231 relative to the long rod 21, that is, adjusting the horizontal deflection angle of the display module 30 connected to the plug-in section 2321.

[0044] Optionally, the rotating connection assembly 23 further includes a side cover 234 and a crossbar 235. The side cover 234 can be installed at the end where the second connecting rod 2334 connects to the first connecting rod 2333, allowing the rotating shaft portion formed by the connection between the first connecting rod 2333 and the second connecting rod 2334 to be enclosed within the side cover 234 and the column 231, reducing the impact of the external environment on the reliability of the rotating shaft portion. The crossbar 235 can be located between the column 231 and the long rod 21, with the other end of the second connecting rod 2334 passing through the crossbar 235 and connecting to the long rod 21. Thus, the crossbar 235 surrounds the outside of the second connecting rod 2334, providing protection for the second connecting rod 2334.

[0045] In some embodiments, please refer to Figure 6 and 7 A cable management channel 213 is provided on one side of the long rod 21. The infrared host 10 is electrically connected to the display module 30 via a cable 40, and part of the cable 40 is stored in the cable management channel 213. The cable management channel 213 is provided on the long rod 21, such as... Figure 8 As shown, taking the helmet as an example of an external device 50, after one end of the cable 40 is connected to the infrared host 10 installed on one side of the helmet 50, it can be routed from the back of the helmet 50 to the position of the long rod 21 installed on the other side of the helmet 50. At this time, the cable 40 can be stored in the cable management groove 213 of the long rod 21, and then the cable 40 can extend along the extension direction of the long rod 21 to the end of the long rod 21 in the cable management groove 213 to be electrically connected to the display module 30.

[0046] The long rod 21 includes a hollow portion 212 and a groove portion 211 located below the hollow portion 212; the cross-section of the hollow portion 212 is a closed annulus, and the cross-section of the groove portion 211 is an annulus with at least one side open, specifically as follows: Figure 7The cross-section of the cable groove 211 is hook-shaped. The hollow portion 212 on the long rod 21 reduces its weight, contributing to its lightweight design while maintaining its rigidity. The hook-shaped cable groove 211 can house the cable 40 and prevent it from coming out, while also protecting it from external damage and preventing it from swaying during use. This is especially important when mounting a modified thermal imaging device onto a helmet, as it prevents the user from being affected by the cable swaying. Multiple spaced connection holes can be provided on the end of the long rod 21 that connects to the helmet, allowing the user to select one for installation and adjust the length of the long rod 21 protruding in front of the eyes. The end of the long rod 21 that connects to the display module 30 can be rigidly fixed to the rotating connection assembly 23 with screws, ensuring the stability of the display module 30 connected to the long rod 21 via the rotating connection assembly 23 when mounted on the external device 50. Optionally, the long rod 21 can also be an adjustable telescopic rod, allowing users to adjust the length of the long rod 21 protruding in front of their eyes according to their needs, thereby adjusting the position of the display module 30.

[0047] In some embodiments, please refer to Figure 9 and 10 The display module 30 includes a display screen 31 and a back cover 33 covering the periphery of the display screen 31. The display screen 31 has a built-in hinge fastener 32, which is connected to the rotating connection assembly 23. The back cover 33 provides protection for the display screen 31. Optionally, the back cover 33 can be manufactured using a double-shot molding process, adding drop-resistant features to the four corners of the display screen 31, and using TPU (thermoplastic polyurethane elastic material) to coat the outside, thereby enhancing the drop-resistant performance of the display screen 31, facilitating assembly, and meeting waterproof design requirements. The display module 30 may also include buttons integrated into the back cover 33. The hinge fastener 32, built into the display screen 31, can be an aluminum alloy hinge (BKT) used to connect the rotating connection assembly 23 and the back cover 33. In this embodiment, the hinge fastener 32 can refer to a structural component that mates with the insertion section 2321 of the rotating connection assembly 23, and the hinge fastener 32 may have a receiving hole for the insertion section 2321.

[0048] In some embodiments, the cable 40 is Y-shaped and includes a first interface 41, a second interface 42, and a third interface. The second interface 42 is connected to the display module 30 and has a wire clip structure 421. A wire cover 331 corresponding to and fixed to the wire clip structure 421 is connected to the rear shell 33. The first interface 41 is connected to the infrared host 10, and the third interface is used to connect to a power bank. In this embodiment, the cable 40 is a Y-shaped customized cable 40, with its three separate ends forming the first interface 41, the second interface 42, and the third interface, respectively, to connect the display module 30, the infrared host 10, and the power bank. The power bank is an independent module relative to the infrared host 10 and the display module 30. Using a relatively independent and separately configured power bank to supply power to the infrared host 10 and the display module 30 helps to reduce the weight of the parts assembled on the external device 50. The second interface 42, which connects to the display module 30, is equipped with a wire clip structure 421. The design of the rear shell 33 of the display module 30 allows it to form a wire cover 331 that engages and is fixed to the wire clip structure 421. When the second interface 42 is plugged into the display module 30, the wire clip structure 421 is fixed to the wire cover 331 before electrical connection is made. This improves the reliability of the plug-in connection between the second interface 42 and the display module 30. After the second interface 42 is locked to the rear shell 33 of the display module 30, it can be secured with screws. Thus, the connection between the cable 40 and the infrared host 10 and the display module 30 does not form an exposed interface, effectively improving connection reliability.

[0049] It should be noted that the connectors used for electrical connections among the second interface 42 connecting the cable 40 to the display module 30, the first interface 41 connecting the cable 40 to the infrared host 10, and the third interface connecting the cable 40 to the power bank can be conventional interface types, which will not be elaborated upon in this application. The cable 40 connects the display module 30, the infrared host 10, and the power bank using its three-terminal interface. While the power bank supplies power to the infrared host 10 and the display module 30, it also enables data transmission between the infrared host 10 and the display module 30. In other embodiments, the infrared host 10 and the display module 30 may each be equipped with a communication module, enabling data transmission wirelessly.

[0050] In some embodiments, please refer again Figure 8The outer casing 11 of the infrared main unit 10 includes a front casing 113 and a bottom casing 114. The front casing 113 is injection molded from plastic material, and the bottom casing 114 is made of aluminum alloy. This design allows the outer casing 11 to both dissipate heat and reduce the weight of the main unit. Optionally, the outer casing 11 also includes a lens cover 13 covering the outside of the infrared lens 12 and a connecting strap 131 connecting the lens cover 13 to the outer casing 11. The lens cover 13 has a reverse-hanging structure 132 on the opposite side away from the connecting strap 131. After the lens cover 13 is removed from the infrared lens 12, it can be connected to the rear side of the outer casing 11 through the reverse-hanging structure 132. The lens cover 13 can be made of silicone material. With the design of the reverse-hanging structure 132, after the user opens the lens cover 13, the reverse-hanging structure 132 can be used to fix the lens cover 13 to the outer casing 11, thereby effectively avoiding interference to the user wearing the helmet caused by the shaking of the lens cover 13 during the use of the modified thermal imaging device, especially when the modified thermal imaging device is mounted on a helmet.

[0051] Overall, the modified thermal imaging device provided in this application embodiment has at least the following characteristics: First, unlike traditional user modification methods, a complete set of retrofit thermal imaging devices has been specifically designed for aftermarket installation on external devices, such as helmets.

[0052] Secondly, the display module 30 has a back cover designed for the display screen 31, and the interfaces of the cable 40 connecting the infrared host 10 and the display module 30 are designed with auxiliary locking structures, so that the cable 40 is firmly and reliably connected, thus ensuring the stability of data transmission.

[0053] Third, the design of the long rod 21 effectively improves the stability of the display module 30 after it is mounted on the helmet, and also serves to store and protect the cable 40, preventing wear and shaking of the cable 40. The cable 40 is also a key component for image data acquisition and display in the retrofitted thermal imaging device. The cable management groove 213 on the long rod 21 helps to store and protect the cable 40, thus improving the overall lifespan of the product. Secondly, the design of the long rod 21 in conjunction with the rotating connection component 23 fully considers the differences in user experience. The length of the long rod 21 protruding from the front of the helmet can be adjusted by using the assembly between the long rod 21 and the helmet 50, and the angle can be freely adjusted using the rotating connection component 23.

[0054] Fourth, it fully considers product maintenance needs and supports the disassembly of various modules such as the infrared host 10, long rod 21, rotating connection component 23, and display module 30 in the retrofit thermal imaging equipment, which facilitates after-sales maintenance and reduces usage costs.

[0055] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0056] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
