[0004] This invention provides an infrared thermal imaging device to solve the problem that existing infrared thermal imaging devices only provide infrared thermal imaging functions, and users need to use additional equipment when they need to acquire thermal imaging images and visible light image information at the same time, resulting in poor operation convenience.

[0005] This utility model provides an infrared thermal imaging device, comprising: a housing having a receiving cavity, the housing having a front wall and a rear wall disposed opposite to each other; an infrared module including an infrared camera disposed on the rear wall of the housing; a visible light module including a visible light camera disposed on the rear wall of the housing; a control module disposed within the receiving cavity; and a display module including a display screen disposed on the front wall of the housing; the infrared module, the visible light module, and the display module are electrically connected to the control module respectively, so that the display screen displays image information captured by the infrared camera and the visible light camera.

[0006] Furthermore, the infrared thermal imaging device also includes a wireless communication module, which is disposed within the receiving cavity and is electrically connected to the control module.

[0007] Furthermore, the control module includes a PCB board assembly, and the wireless communication module is a thin-film structure. Both the control module and the wireless communication module are parallel to the front wall of the housing and are arranged along the direction from the front wall to the rear wall of the housing.

[0008] Furthermore, the infrared thermal imaging device also includes: a support unit disposed within a receiving cavity, and a display screen disposed on the support unit.

[0009] Furthermore, the support is a plate-like structure, and the support is parallel to the display screen.

[0010] Furthermore, the infrared thermal imaging device also includes: a control key located inside the receiving cavity, the control key being disposed on the control module and electrically connected to the control module, and the housing having a flexible part, the flexible part being disposed opposite to the control key, the flexible part deforming under the action of external force and applying force to the control key.

[0011] Furthermore, the infrared thermal imaging device also includes: an abutment portion disposed on the inner surface of the flexible portion, the abutment portion having a harder hardness than the flexible portion, the abutment portion being used to abut or separate from the control key.

[0012] Furthermore, the infrared thermal imaging device also includes: a power supply module disposed within the receiving cavity, the power supply module and the control module being distributed along the length of the receiving cavity; and / or, a macro lens module detachably disposed on the housing, the macro lens module including a macro lens, the macro lens being positioned directly opposite the infrared camera, the macro lens being used to magnify object imaging; and / or, a speaker disposed within the receiving cavity, the speaker being electrically connected to the control module; and / or, a supplementary lighting module including a white light lamp, the white light lamp being disposed on the rear wall of the housing, the white light lamp being electrically connected to the control module.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0040] like Figures 1 to 3 As shown, this embodiment of the present invention provides an infrared thermal imaging device, which includes a housing 10, an infrared module, a visible light module, a control module 40, and a display module. The housing 10 has a receiving cavity and has a front wall 121 and a rear wall 111 disposed opposite to each other; the infrared module includes an infrared camera 20, which is disposed on the rear wall 111 of the housing 10; the visible light module includes a visible light camera 30, which is disposed on the rear wall 111; the control module 40 is disposed in the receiving cavity; the display module includes a display screen 50, which is disposed on the front wall 121 of the housing 10; the infrared module, the visible light module, and the display module are electrically connected to the control module 40, so that the display screen 50 displays image information captured by the infrared camera 20 and the visible light camera 30.

[0041] It is understandable that visible light image information refers to information captured by a visible light camera, which can provide a rich visible light visual description of object shape, environmental conditions, scene details, etc.

[0042] In some embodiments of this solution, the display screen 50 also has a touch screen function. Users can freely switch between display modes of infrared thermal imaging and visible light images, adjust display parameters, or make other function settings by directly touching the display screen 50 according to their needs. Touch screen operation also provides a more convenient means. Users can complete various operations without additional physical buttons or cumbersome setup processes, thereby improving the efficiency of device use and user satisfaction.

[0043] Specifically, during use, the display screen 50 can simultaneously display visible light images and infrared thermal images, or display a single image, according to the user's needs.

[0044] Furthermore, the infrared thermal imaging device also includes a wireless communication module 60, which is disposed within the receiving cavity and electrically connected to the control module 40. Through the cooperation of the wireless communication module 60 and the control module 40, users can share infrared thermal images and visible light images to other devices, such as smart devices (e.g., mobile phones, tablets, laptops) or cloud servers. This facilitates temperature analysis, fault diagnosis, or safety monitoring remotely, which is crucial for scenarios such as remote diagnostics and real-time monitoring.

[0045] This solution does not limit the specific form of the wireless communication module 60, which may include wireless communication modules such as Wi-Fi and Bluetooth.

[0046] In this embodiment of the solution, the wireless communication module 60 includes a Wi-Fi module and a Bluetooth module.

[0047] Furthermore, the control module 40 includes a PCB board assembly, and the wireless communication module 60 is a thin-film structure. Both the control module 40 and the wireless communication module 60 are parallel to the front wall 121 of the housing 10, and are arranged along the direction from the front wall 121 to the rear wall 111 of the housing 10. This arrangement optimizes the layout of the control module 40 and the wireless communication module 60 within the receiving cavity, minimizing the space occupied by the control module and the wireless communication module 60 within the receiving cavity, thus contributing to the miniaturization of this device.

[0048] To enhance the stability of the display screen 50, the infrared thermal imaging device also includes a support 51, which is disposed within the receiving cavity, and the display screen 50 is mounted on the support 51. The support 51 provides a robust mounting base for the display screen 50, reducing vibration and displacement of the display screen 50 within the device. Especially when the device is subjected to accidental impact or vibration, it can effectively protect the display screen 50 and prevent malfunction or failure due to physical damage.

[0049] Furthermore, the support portion 51 is made of a material with thermal conductivity. This design allows the support portion 51 to exchange heat with the display screen 50, preventing performance degradation or shortened lifespan of the display screen 50 due to overheating, and ensuring the stable display performance of the display screen 50.

[0050] Specifically, a mounting port is provided on the front wall 121 of the housing 10, which communicates with the receiving cavity. The display screen 50 is positioned corresponding to the mounting port and is bonded to the front wall 121 of the housing 10 using a high-viscosity medium. The use of the high-viscosity medium not only ensures the stable installation of the display screen 50 but also provides a good sealing effect, effectively preventing moisture, dust, and other external substances from entering the equipment, ensuring the equipment's waterproof and dustproof rating, and extending its service life. This is particularly important in harsh environments such as outdoor operations or industrial testing. Furthermore, the above configuration simplifies the equipment assembly process and improves production efficiency. During assembly, the operator only needs to accurately place the display screen 50 in the mounting port position and fix it using the high-viscosity medium, eliminating the need for complex mechanical connections or adjustments. This reduces assembly difficulty and potential assembly errors, contributing to improved product quality and consistency.

[0051] Furthermore, the support portion 51 has a plate-like structure and is parallel to the display screen 50. The plate-like design and parallel layout of the support portion 51 help optimize the internal space layout of the device, allowing for a more compact design and reducing wasted internal space. Moreover, the parallel position of the support portion 51 to the display screen 50 also facilitates internal heat dissipation design. It is understood that the support portion 51, the control module 40, and the wireless communication module 60 are arranged sequentially along the direction from the front wall 121 to the rear wall 111 of the housing 10.

[0052] The support 51 can be fixed to the housing 10 by fasteners or other types of connection. The control module 40 and the wireless communication module 60 can be mounted on the support 51 or on the housing 10 for fixation.

[0053] like Figure 1 and Figure 4 As shown, the infrared thermal imaging device further includes a control key 70. The control key 70 is located within the receiving cavity and is mounted on and electrically connected to the control module 40. The housing 10 has a flexible portion 101, which is directly opposite the control key 70. Under external force, the flexible portion 101 deforms and applies force to the control key 70. The control key 70's location within the receiving cavity and direct electrical connection to the control module 40 avoids direct impact from external environmental factors (such as dust and moisture) on the control key 70, improving its reliability and durability. Simultaneously, by having the flexible portion 101 on the housing 10 directly opposite the control key 70, the user only needs to apply appropriate pressure to the flexible portion 101 to transmit force to the control key 70 through deformation, achieving precise control of the device's functions. This design not only improves operational convenience but also makes the control process more intuitive.

[0054] In this design, the flexible part 101 is made of an elastic material, such as silicone or TPE (thermoplastic elastomer). These materials not only provide a good feel but also absorb external impacts to a certain extent, effectively protecting the control key 70 and other internal components of the device from physical damage. Simultaneously, the combination of the flexible part 101 and the housing 10 helps improve the device's waterproof and dustproof performance, ensuring stable operation of the device in harsh environments.

[0055] Specifically, multiple control keys 70 can be provided, which can be power switch, photo / video capture key, mode switching key (such as thermal imaging / visible light switching, single display / dual display switching), etc. Furthermore, flexible parts 101 corresponding to the positions of the multiple control keys 70 are provided on the side wall of the housing 10 along the length direction. The multiple flexible parts 101 are distributed at intervals along the length direction of the housing 10 on the side wall of the housing 10.

[0056] Furthermore, the infrared thermal imaging device also includes a contact portion 102, which is disposed on the inner surface of the flexible portion 101. The hardness of the contact portion 102 is greater than that of the flexible portion 101. The contact portion 102 is used to contact or separate from the control key 70. The greater hardness of the contact portion 102 means that when the user presses the flexible portion 101, the contact portion 102 can transmit force to the control key 70 more directly and effectively, reducing force attenuation and dispersion, thereby improving control accuracy and response speed. Since the contact portion 102 directly contacts the control key 70 and the non-flexible portion 101, this reduces wear and aging of the flexible portion 101 caused by frequent contact, thereby extending the service life of the flexible portion 101.

[0057] like Figure 3 As shown in the embodiment of this solution, the infrared thermal imaging device also includes a power supply module 80, which is disposed within the receiving cavity. The power supply module 80 and the control module 40 are distributed along the length of the receiving cavity. This arrangement makes full use of the linear space inside the device, avoiding excessive occupation in the width or height of the receiving cavity, allowing the infrared thermal imaging device to be designed to be more compact and lightweight, facilitating user portability and operation in confined spaces. Furthermore, the power supply module 80 and the control module 40 can be directly connected via straight or slightly curved cables, reducing the possibility of cable crossing and tangling, lowering the risk of internal circuit failures, and facilitating device assembly and maintenance.

[0058] It is understandable that the power supply module 80 is the component of this device that requires power, such as the control module 40, infrared module, visible light module, display screen 50, wireless communication module 60, etc.

[0059] like Figure 5As shown, in some embodiments of this solution, the infrared thermal imaging device further includes a macro lens module 90, which is detachably mounted on the housing 10. The macro lens module 90 includes a macro lens, which is positioned opposite the infrared camera 20. The macro lens is used to magnify the image of the object. The macro lens and the infrared camera 20 are positioned opposite each other and work together to capture more detailed and clearer infrared images. The detachable design of the macro lens module 90 allows the infrared thermal imaging device to flexibly adjust its functions according to different usage scenarios. When macro observation is required, the user can install the macro lens module 90; when performing routine observation, the macro lens module 90 can be removed, restoring the device's portability and versatility. This design greatly expands the device's application range and meets the dual needs of professional testing and daily observation. Simultaneously, the installation and removal of the macro lens module 90 does not require opening the main body of the device, maintaining the device's airtightness and helping to maintain its waterproof and dustproof performance.

[0060] In addition, the infrared thermal imaging device also includes a speaker, which is housed within the receiving cavity and electrically connected to the control module 40. The integrated speaker provides an audible alarm function; when the thermal imaging sensor detects abnormally high or low temperatures or other preset temperature thresholds, the speaker emits an alarm sound to alert the user to potential safety hazards. Furthermore, the speaker can play voice navigation and operational feedback to help users more intuitively understand the device status and operational results. For example, when the device starts up, switches modes, or completes image capture, the speaker can play corresponding confirmation tones, enhancing the certainty and comfort of user operation.

[0061] like Figure 2 As shown, the infrared thermal imaging device further includes a supplementary lighting module, which includes a white light lamp 100. The white light lamp 100 is disposed on the rear wall 111 of the housing 10 and is electrically connected to the control module 40. The white light lamp 100 provides an additional light source for the device, facilitating shooting at night or in dim environments.

[0062] like Figure 3 As shown, specifically, the housing 10 includes a rear housing 11 and a front housing 12. The infrared camera 20, the visible light camera 30, and the white light lamp 100 are all mounted on the rear housing 11; the display screen 50 is mounted on the front housing 12. The front housing 12 and the rear housing 11 are detachably connected. This layout concentrates the imaging and supplementary lighting functions on the rear side of the device, making it easier for the user to hold the device naturally during operation. Simultaneously, placing the display screen on the front side, facing the user directly, facilitates viewing thermal and visible light images. This design not only optimizes the functional layout of the device but also makes the operation more ergonomic, improving the user experience. Furthermore, the detachable connection between the front housing 12 and the rear housing 11 enhances the ease of assembling the entire device.

[0063] This solution does not limit the specific connection method between the front shell 12 and the rear shell 11. In the embodiments of this solution, the rear shell 11 includes a rear wall 111 and a side wall 112. The side wall 112 is arranged in a ring around the periphery of the rear wall 111. The front shell 12 includes a front wall 121. The front shell 12 is fastened to the side of the side wall 112 away from the rear wall 111. The infrared thermal imaging device also includes a fastening assembly 13, which is disposed between the front shell 12 and the side wall 112. The front shell 12 and the rear shell 11 are connected by the fastening assembly 13.

[0064] Furthermore, one end of the front shell 12 in the length direction also has an arc-shaped bend 122. After the front shell 12 and the rear shell 11 are fastened together, the bend 122 abuts against the corresponding part of the side wall 112 of the rear shell 11.

[0065] like Figure 3 and Figure 6 As shown, the fastening assembly 13 may include a connecting block and a fastening bolt. The connecting block is disposed on the inner surface of the front shell 12. After the front shell 12 and the rear shell 11 are fastened together, the connecting block is in contact with the inner surface of the side wall 112. The fastening bolt passes through the side wall 112 and is threadedly connected to the connecting block.

[0066] like Figure 3 and Figure 7 As shown, the infrared thermal imaging device further includes a snap-fit ​​assembly 14, which is disposed between the front shell 12 and the side wall 112, and the front shell 12 and the rear shell 11 are snapped together by the snap-fit ​​assembly 14.

[0067] The snap-fit ​​assembly 14 includes a snap-fit ​​block and a snap-fit ​​groove. The snap-fit ​​block is disposed on one of the side wall 112 and the front shell 12, and the snap-fit ​​groove is disposed on the other side wall 112 and the front shell 12. The snap-fit ​​block and the snap-fit ​​groove are snap-fitted together.

[0068] In summary, the infrared thermal imaging device of this utility model improves the overall ease of operation of the device through a series of innovative designs, such as integrated imaging, touch screen operation, wireless communication, the arrangement of various components in the accommodating space, optimized internal heat dissipation, enhanced protective performance, and improved macro imaging capabilities.
