[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0073] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0074] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a handheld infrared device provided in an embodiment of this application from a first perspective. Figure 2 A schematic diagram of a handheld infrared device provided in an embodiment of this application from a second perspective.

[0075] In a first specific embodiment, the handheld infrared device provided in this application mainly includes a device body 1 and a device bracket 2. The device body 1 is provided with an infrared detection module 101, a functional circuit board 102 and a data interface 103. The infrared detection module 101 and the data interface 103 are both electrically connected to the functional circuit board 102. The device bracket 2 is located on the device body 1 and is used to install a display device. The display device is electrically connected to the data interface 103 through a data cable, and the thermal image is displayed on the display device.

[0076] In some cases, the display device is a smartphone.

[0077] The working principle is that the infrared detection module 101 acquires the light signal, and the functional circuit board 102 performs data reception, data processing, and data transmission.

[0078] In the background technology, traditional handheld infrared devices have an increased overall size and weight due to the integration of a built-in display screen. This makes the portability of the device a significant drawback, especially in scenarios that require frequent movement or rapid deployment.

[0079] To address this issue, this technical solution proposes an innovative design: integrating an infrared detection module 101, a functional circuit board 102, and a data interface 103 into the main body of the device 1, while transferring the display function to a smartphone. This design allows the main body of the device 1 to focus on its core functions of infrared detection and data processing without the need for an additional integrated display screen, thereby reducing the size and weight of the device.

[0080] The device bracket 2 allows users to directly mount a smartphone onto the device body 1 and view thermal images using the phone's display, eliminating the need for an integrated display on the handheld infrared device. Smartphone displays typically have high resolution and user-friendly interfaces, providing a superior visual experience compared to the built-in displays on traditional handheld infrared devices. Furthermore, the data interface 103 connects to the smartphone via a data cable, enabling efficient data transmission, simplifying the device design, and allowing images and data to be displayed on the smartphone. This design not only reduces the physical burden on the device but also improves user convenience in various environments, especially in scenarios requiring frequent movement or rapid deployment.

[0081] Based on the above structural and process descriptions, it can be seen that the handheld infrared device has at least the following beneficial effects: when used in conjunction with a mobile phone, the handheld infrared device overcomes the size and weight problems caused by the built-in display screen of traditional devices, and improves the portability and operational flexibility of the device.

[0082] Please refer to Figure 3 , Figure 3 A schematic diagram of a handheld infrared device provided in an embodiment of this application from a third perspective.

[0083] In some embodiments, the device body 1 is provided with a mounting base 104;

[0084] The device bracket 2 includes a clamp 201 and a clamping component 202 disposed on the clamp 201. The clamp 201 is rotatably connected to the mounting base 104 to adjust the display orientation of the display device, such as a mobile phone. The clamping component 202 is used to clamp the display device, such as a mobile phone.

[0085] In this embodiment, the device body 1 is provided with a mounting base 104, and the device bracket 2 is composed of a clamp 201 and a clamping assembly 202. The connection between the clamp 201 and the mounting base 104 is a rotatable connection. This design allows users to adjust the display orientation of the mobile phone as needed for better viewing of thermal imaging images.

[0086] The main function of the clamping assembly 202 is to hold the mobile phone, ensuring that it is securely fixed to the device body 1 during use. Since the rotatable connection between the clamp 201 and the mounting base 104 is not limited to single-axis rotation, a ball joint structure can be used to achieve omnidirectional rotation. This flexible rotation method allows users to freely adjust the angle of the mobile phone according to different working environments and needs, thereby improving the ease of use and flexibility of the device. Simultaneously, the multi-angle adjustment function helps to achieve the fusion of images captured by the mobile phone camera and those captured by the infrared device.

[0087] In some embodiments, the clamping assembly 202 includes a clamping rod 2021 and a chuck 2022, wherein the clamping rod 2021 is slidably connected to the clamping seat 201 and the chuck 2022 is rotatably connected to the clamping rod 2021.

[0088] In this embodiment, the clamping assembly 202 is an important component of the device bracket 2, designed for clamping and securing the mobile phone. The clamping assembly 202 consists of two main parts: a clamping rod 2021 and a clamping head 2022. The clamping rod 2021 is slidably connected to the clamping base 201, allowing it to extend or retract along its width or length to accommodate mobile phones of different sizes. The clamping head 2022 is rotatably connected to the clamping rod 2021, enabling it to rotate around the clamping rod 2021 for a more reliable grip on the edge of the mobile phone.

[0089] Optionally, elastic elements can be provided at corresponding positions on the clamping rod 2021 and the clamp 2022. For example, a spring can be provided in the extension and retraction direction of the clamping rod 2021. When the clamping rod 2021 is pulled to a position suitable for the phone size, the spring can provide a restoring force, causing the clamp 2022 to clamp the phone, and automatically returning the clamping rod 2021 to its initial state after the phone is removed. Alternatively, a torsion spring can be provided in the rotation direction of the clamp 2022. Utilizing the elasticity of the torsion spring, when the clamp 2022 swings to an appropriate position, it clamps the phone, and automatically returns to its initial state after the phone is removed.

[0090] A further optional design is to symmetrically arrange two sets of grippers in the clamping assembly 202. Each gripper consists of a clamping rod 2021 and a clamping head 2022, which can stably hold the phone. Each set of grippers has two clamping rods 2021 and clamping heads 2022, thus providing four clamping points under the action of the two sets of grippers, making the phone more securely clamped to the device holder. This design not only provides better phone fixation but also enhances the stability and balance of the entire clamping assembly, reducing the risk of the phone falling off due to accidental collisions or movement, and improving safety and reliability during use.

[0091] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the device bracket provided in the embodiments of this application when it is folded up.

[0092] like Figure 4 As shown, when the clamping bar 2021 is retracted and the clamp head 2022 is folded, the clamping assembly 202 can be compactly integrated with the clamp base 201 into a single unit, significantly reducing the space occupied. This design is particularly suitable for scenarios requiring frequent movement or storage of device racks, as it allows users to easily fold the racks for convenient carrying and storage.

[0093] A groove is provided on the clamp base 201 to provide a storage space, allowing the clamp head 2022 to fold into it after the clamping rod 2021 is fully retracted. This design not only enhances the overall integrity of the clamping assembly 202 and the clamp base 201 but also improves the aesthetics and neatness of the bracket. When the clamp head 2022 is folded into the groove, the entire device bracket presents a more compact and streamlined appearance, while also protecting the clamp head 2022 from accidental damage or scratches to other items during transport.

[0094] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the infrared detection module and lens provided in the embodiments of this application.

[0095] In some embodiments, a lens 3 disposed on the device body 1 is also included;

[0096] The infrared detection module 101 includes an adjustment mechanism 1011 and a sensing device 1012 disposed on the adjustment mechanism 1011. The adjustment mechanism 1011 can adjust the distance between the sensing device 1012 and the lens 3.

[0097] In this embodiment, the main body 1 integrates a lens 3, which is an important component for handheld infrared devices because it directly affects the device's imaging quality and temperature measurement accuracy. The design of the lens 3 allows the device to capture precise images of the target object, which is crucial for accurate temperature measurement.

[0098] The infrared detection module 101 consists of an adjustment mechanism 1011 and a sensing device 1012. The sensing device 1012 is responsible for sensing the infrared radiation captured by the lens 3, while the adjustment mechanism 1011 is responsible for adjusting the distance between the sensing device 1012 and the lens 3. This design solves the limitations of traditional small focal length or fixed focal length lenses in terms of autofocus, because these lenses are difficult to integrate complex electric focusing mechanisms due to size constraints.

[0099] Traditionally, small lenses, due to their small size, are difficult to integrate with motors and gear structures, which limits their application in autofocus functions and affects imaging flexibility and user experience. However, this application achieves autofocus functionality on small lenses through an innovative design. This design allows the adjustment mechanism 1011 to adjust the distance between the sensing device 1012 and the lens 3, thereby achieving autofocus. This not only improves imaging flexibility but also enhances the user experience.

[0100] This autofocus mechanism allows the equipment to quickly adapt to different observation conditions and target distances, ensuring consistently clear and accurate images. This is crucial for improving the accuracy and reliability of measurements, especially in high-precision applications such as outdoor power line inspection.

[0101] It should be noted that the infrared detection module 101 in this embodiment is not limited to a specific sensing principle, allowing for a wide range of applications. The sensing device 1012 can employ different sensing technologies; whether it is a device based on an infrared detector or a device based on a visible light sensor, it can be included within the scope of this embodiment.

[0102] Please refer to Figure 6 , Figure 6 An exploded view of the infrared detection module, lens, and functional circuit board provided in the embodiments of this application.

[0103] In some embodiments, the sensing device 1012 includes a sensing element 10121 and a sensing circuit board 10122. The sensing circuit board 10122 is disposed on the device body 1 and is electrically connected to the functional circuit board 102. The sensing element 10121 is disposed on the adjustment mechanism 1011, and the sensing element 10121 and the sensing circuit board 10122 are electrically connected through a flexible ribbon cable 10123.

[0104] In this embodiment, the design of the sensing device 1012 has two significant features to improve the performance and reliability of the autofocus structure.

[0105] The sensing device 10121 and the sensing circuit board 10122 are arranged separately. This layout avoids the adverse effects that the heat generated by the sensing circuit board 10122 during operation may have on the sensing device 10121. Since the sensing device 10121 is generally sensitive to temperature changes, this separation design helps to keep the sensing device 10121 operating in a relatively stable environment, thereby ensuring the accuracy and stability of the sensing data.

[0106] The use of the flexible ribbon cable 10123 enables the electrical connection between the sensing device 10121 and the sensing circuit board 10122. This design allows the sensing device 10121 to move freely under the action of the adjustment mechanism 1011, while the sensing circuit board 10122 can be fixed to the main body 1 of the device. The design of the flexible ribbon cable 10123 satisfies both the mechanical structural requirements and ensures the reliability of the electrical connection, which is crucial for maintaining precise control of the autofocus structure during dynamic focusing. In this way, even when the sensing device 10121 moves to adjust the distance between itself and the lens 3, communication with the sensing circuit board 10122 remains uninterrupted, thereby achieving precise autofocus functionality.

[0107] It should be noted that the sensing device 10121 can be either an infrared detector or a visible light sensor, and both should fall within the scope of this embodiment.

[0108] Optionally, the sensing circuit board 10122 and the functional circuit board 102 are connected by a connector.

[0109] In some embodiments, the lens 3 is threadedly connected to the device body 1, and the distance between the lens 3 and the sensing device 1012 is adjusted by rotating the lens 3.

[0110] In this embodiment, the lens 3 is connected to the device body 1 via a threaded connection. This design allows the distance between the lens 3 and the sensing device 1012 to be adjusted by manually rotating the lens 3. This adjustment method provides a manual focusing function, allowing the user to focus directly by operating the lens 3 as needed. This is very useful in certain emergency or specific situations, such as when the adjustment mechanism 1011 loses power, unexpectedly jams, or experiences a circuit failure, allowing the user to still focus manually.

[0111] Meanwhile, under the action of the adjustment mechanism 1011, the sensing device 1012 can automatically adjust its distance from the lens 3 to achieve autofocus. This means that the autofocus structure not only has the ability to autofocus, but also retains the flexibility of manual focusing. This design allows the autofocus structure to adapt to more application scenarios and user needs, providing an effective solution whether it is a situation requiring fast manual focusing or an environment requiring precise autofocus.

[0112] In some embodiments, the outer side of the lens 3 is provided with an external thread that is threadedly connected to the device body 1, and the inner side of the lens 3 is provided with an internal thread. The internal thread is threadedly connected to the anti-detachment ring, and the adjustment range of the lens 3 is limited by the action of the device body 1 on the anti-detachment ring.

[0113] In some cases, the anti-detachment ring has protrusions on its periphery. The number of protrusions can be two, symmetrically arranged. The mechanical restraint of the protrusions by the device body 1 limits the adjustment range of the lens 3, preventing excessive rotation or accidental detachment of the lens 3 from the device body 1. Simultaneously, it restricts the lens 3 to a specific distance range relative to the sensing device 1012, ensuring that regardless of the lens 3's position, automatic focusing ensures that the image plane of the sensing device 10121 is always at the focal point of the lens 3.

[0114] Alternatively, the sensing device 10121 in the sensing device 1012 can be either an infrared detector or a visible light sensor; there is no limitation on this.

[0115] In some embodiments, the device body 1 is provided with a fixed bracket 105 and a plate bracket 106, the plate bracket 106 is connected to the fixed bracket 105, and the plate bracket 106 is provided with a functional circuit board 102 and a sensing circuit board 10122.

[0116] The adjustment mechanism 1011 includes a drive assembly 10111, a motion bracket 10112, and a mounting bracket 10113. The drive assembly 10111 is disposed on the fixed bracket 105. The drive end of the drive assembly 10111 is connected to the motion bracket 10112. The motion bracket 10112 is slidably connected to the fixed bracket 105. The mounting bracket 10113 is connected to the motion bracket 10112. The mounting bracket 10113 is provided with the sensing device 10121.

[0117] In this embodiment, the board support 106 is connected to the fixed support 105 and is provided with a functional circuit board 102 and a sensing circuit board 10122. This structural design allows the circuit board to be fixed in a stable position, facilitating connection and maintenance.

[0118] The adjustment mechanism 1011 consists of a drive assembly 10111, a motion bracket 10112, and a mounting bracket 10113. The drive assembly 10111 is mounted on the fixed bracket 105 and serves as the power source for the adjustment mechanism 1011, responsible for driving the movement of the entire adjustment mechanism 1011. The drive end of the drive assembly 10111 is connected to the motion bracket 10112, enabling the motion bracket 10112 to move precisely within the device body 1, thereby adjusting the distance between the sensing device 1012 and the lens 3.

[0119] The motion support 10112 and the fixed support 105 are slidably connected. This design allows the motion support 10112 to move freely on the fixed support 105, enabling precise adjustment of the position of the sensing device 1012. The mounting bracket 10113 is connected to the motion support 10112 and moves together with it. The mounting bracket 10113 is equipped with the sensing device 10121, ensuring the stability of the sensing device 10121 during movement.

[0120] In some cases, a first fastener 114 is used to achieve a fixed connection, such that the sensing circuit board 10122 and the functional circuit board 102 are fixed to the first fastener 114 by a board bracket 106. The first fastener 114 fixes the fixing bracket 105 and the board bracket 106 to the housing 110 of the device body 1.

[0121] In some cases, the mounting bracket 10113 is provided with a heat sink 115 that contacts the sensing device 10121. The heat sink 115 is used to press and fix the sensing device 10121 onto the mounting bracket 10113. This design ensures that the heat generated by the sensing device 10121 during operation can be effectively conducted to the heat sink 115, thereby keeping the sensing device 10121 within a suitable operating temperature range, which is crucial for maintaining the performance of the sensing device 10121 and extending its service life.

[0122] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the drive assembly and motion support provided in the embodiments of this application.

[0123] In some embodiments, the driving component 10111 includes:

[0124] The driving component 101111 is mounted on the fixed bracket 105;

[0125] The drive rod 101112 is connected to the drive component 101111, and the drive rod 101112 is threaded.

[0126] The motion support 10112 is provided with a transmission body 101121. The transmission body 101121 has an opening and a drive rod 101112 is sleeved on it. The transmission body 101121 and the drive rod 101112 are threaded together.

[0127] The motion support 10112 is also equipped with a positioning bearing 101122, which cooperates with the fixed support 105.

[0128] In this embodiment, the drive assembly 10111, as the core component of the adjustment mechanism 1011, is responsible for providing power and transmitting it to the motion support 10112 to achieve precise position adjustment of the sensing device 1012. The drive assembly 10111 consists of a drive element 101111 and a drive rod 101112. The drive element 101111 is fixed to the fixed support 105 and is typically a motor or other type of drive device responsible for generating power. The drive rod 101112 connected to it is threaded to realize the power conversion of the drive element 101111.

[0129] The transmission element 101121 on the motion bracket 10112 is fitted onto the drive rod 101112 through an opening and engages with the drive rod 101112 via threads, enabling precise movement along the drive rod 101112. This threaded engagement not only transmits power but also ensures the smoothness and accuracy of the movement. Furthermore, the motion bracket 10112 is equipped with a positioning bearing 101122, which works in conjunction with the fixed bracket 105 to ensure that the motion bracket 10112 moves linearly along the drive rod 101112, preventing lateral deviation or rotation, and improving the stability and adjustment accuracy of the adjustment mechanism 1011.

[0130] In particular, the drive component 101111 has the ability to rotate in both forward and reverse directions. When the drive component 101111 drives the drive rod 101112 to rotate in different directions, the motion support 10112 can move in both forward and backward directions.

[0131] In some cases, there are two positioning bearings 101122, which are arranged symmetrically to guide the movement between the fixed bracket 105 and the moving bracket 10112.

[0132] In one specific embodiment, the main body of the device 1 is provided with a housing 110, in which an infrared detection module 101, a functional circuit board 102, a fixing bracket 105, and a board bracket 106 are provided. The data interface 103 is located on the side of the housing 110, the mounting base 104 is located on the back of the housing 110, the lens 3 is mounted on the front of the housing 110, and the device bracket 2 is mounted on the back of the housing 110.

[0133] Please refer to Figure 8 , Figure 8 An exploded view of the first button, the second button, and the button circuit board provided in the embodiments of this application.

[0134] In some embodiments, the main body 1 of the device is provided with a button circuit board 107, a first button 108, a second button 109 and a housing 110. The first button 108 is slidably connected to the housing 110, and the second button 109 is rotatably connected to the housing 110. The button circuit board 107 is electrically connected to the function circuit board 102. The button circuit board 107 can generate a signal when triggered by the first button 108 and the second button 109.

[0135] In this embodiment, the main body 1 integrates a button circuit board 107, a first button 108, a second button 109, and a housing 110 to provide user convenience. The first button 108 is slidably connected to the housing 110, allowing relative movement when pressed by the user. This design enables the user to activate the function of the first button 108 with a simple sliding motion. The second button 109 is rotatably connected to the housing 110, allowing relative rotation when operated by the user. The user can activate the function of the second button 109 by rotating it.

[0136] The button circuit board 107 is electrically connected to the function circuit board 102, ensuring that when the first button 108 and the second button 109 are triggered, the button circuit board 107 can generate corresponding signals to achieve the operation expected by the user.

[0137] Through differentiated design, users can intuitively identify and activate different functions by the movement of the buttons (sliding or rotating), avoiding confusion caused by similar button appearances and layouts. If a user presses the wrong button using the incorrect control method, the differentiated feedback allows for quick detection and correction. This intuitive operation improves the accuracy and efficiency of user operations, reduces the risk of misoperation in urgent or rapid situations, and thus optimizes the user experience.

[0138] In some embodiments, the device body 1 is provided with a first elastic element 120 and a second elastic element 121, which work in conjunction with the buttons to optimize user experience and button functionality. The first elastic element 120 is associated with a first button 108, while the second elastic element 121 is associated with a second button 109.

[0139] The first elastic element 120 ensures that the first button 108 can quickly and smoothly reset after being pressed, returning to its initial position away from the button circuit board 107. Simultaneously, during the pressing operation of the first button 108, the first elastic element 120 provides appropriate resistance, allowing the user to feel clear feedback during operation, enhancing the accuracy and satisfaction of the operation. This design allows the user to activate the function of the button circuit board 107 through the sliding action of the first button 108.

[0140] The second elastic element 121 ensures that the second button 109 can also quickly reset after being pressed, returning to its initial position away from the button circuit board 107. During the pressing operation of the second button 109, the second elastic element 121 also provides adaptive resistance, helping the user achieve precise operation and obtain good tactile feedback during operation. This design allows the user to activate the function of the button circuit board 107 by rotating the second button 109.

[0141] Please refer to Figure 9 , Figure 9 An exploded view of the first button, the second button, and the front cover provided in the embodiments of this application.

[0142] In some embodiments, the second button 109 has a first notch 1091, and the first button 108 is located in the first notch 1091.

[0143] In this embodiment, the second button 109 is designed with a specific structure—a first notch 1091. The first notch 1091 is located slightly above the center of the second button 109, and its function is to accommodate the first button 108, so that the first button 108 can be located in this first notch 1091.

[0144] This design allows for a certain degree of vertical overlap between the first button 108 and the second button 109, while maintaining an appropriate gap in the circumferential direction perpendicular to the vertical, ensuring that they do not interfere with each other during operation. Specifically, when the user presses the first button 108, it can move within its free space, triggering its associated switch function without affecting the state of the second button 109. Similarly, when the user operates the second button 109, it can rotate around its pivot point to perform its switch function without interfering with the first button 108.

[0145] This layout not only saves space but also improves the operational efficiency and user experience of the dual-button switch. Each button maintains independent operation capabilities while reducing the possibility of accidental operation, as each button's trigger mechanism and movement are independent. This design also helps improve the device's compactness and portability while maintaining good tactile feedback and operability.

[0146] In some embodiments, the housing 110 is provided with a guide slider 1103, and the first button 108 is provided with a guide groove 1081 that is slidably connected to the guide slider 1103.

[0147] In this embodiment, to ensure that the first button 108 can slide smoothly and accurately on the housing 110, a pair of sliding mechanisms are specially designed, namely a guide slider 1103 and a guide groove 1081. The guide slider 1103 is provided on the housing 110, while the first button 108 is provided with a guide groove 1081 that is slidably connected to the guide slider 1103. This configuration allows the first button 108 to move smoothly along the guide groove 1081 when pressed and slid, thereby triggering the corresponding function.

[0148] By providing a guide slider 1103 on the housing 110 and a guide groove 1081 on the first button 108, smooth operation of the first button 108 is achieved. The combination of the guide groove 1081 and the guide slider 1103 provides precise guidance for the first button 108, allowing the user to obtain better feel and feedback during operation. This design not only improves the comfort and accuracy of operation but also helps extend the lifespan of the button and reduces wear caused by improper operation or excessive friction.

[0149] In some embodiments, the housing 110 is provided with a guide groove 1104, and the second button 109 is provided with a guide protrusion 1092 that is rotatably connected to the guide groove 1104.

[0150] In this embodiment, to ensure that the second button 109 can rotate accurately and smoothly around a fixed axis, a pair of rotating mechanisms are specially designed, namely a guide groove 1104 and a guide protrusion 1092. The guide groove 1104 is provided on the housing 110, while the second button 109 is provided with a guide protrusion 1092 that is rotatably connected to the guide groove 1104. With this configuration, when the second button 109 is rotated, the guide protrusion 1092 rotates along the guide groove 1104, thereby ensuring that the rotation of the second button 109 is both smooth and stable.

[0151] By providing a guide groove 1104 on the housing 110 and a guide protrusion 1092 on the second button 109, precise operation of the second button 109 is achieved. The combination of the guide groove 1104 and the guide protrusion 1092 provides precise guidance for the second button 109, allowing the user to obtain better tactile feedback during operation. This design not only improves the comfort and accuracy of operation but also helps extend the button's lifespan and reduces wear caused by improper operation or excessive friction.

[0152] In some embodiments, the device body 1 is provided with a button bracket 111 and a sealing member 112 provided on the button bracket 111. The button bracket 111 is connected to the outer shell 110. The button bracket 111 is in a foolproof fit with the button circuit board 107. The sealing member 112 separates the button circuit board 107 from the first button 108 and the second button 109.

[0153] In this embodiment, the main body 1 of the device specifically includes a button bracket 111 and a seal 112 to enhance the stability and sealing of the button structure. The button bracket 111 is connected to the outer casing 110 and to the button circuit board 107 in a foolproof manner, ensuring the accuracy and reliability of assembly. The seal 112 serves to seal and isolate the button circuit board 107 from the first button 108 and the second button 109, thereby providing a waterproof effect.

[0154] The housing 110 forms a button cavity, with the first button 108 and the second button 109 located inside the button cavity, while the button circuit board 107 is located outside the button cavity. The button bracket 111 is fixed to the housing 110, ensuring a sealed connection between the sealant 112 and the button cavity, thus guaranteeing a sealed separation between the button and the button circuit board 107. This design not only improves the device's waterproof performance but also ensures that the button circuit board 107 remains dry even in harsh environments such as humid or underwater conditions, preventing moisture intrusion and protecting the electronic device from damage.

[0155] The design of the seal 112 allows it to directly receive the forces exerted by the first button 108 and the second button 109, and transmit these forces to the button circuit board 107. In this way, the seal 112 not only provides a seal but also acts as an intermediate medium for force transmission, ensuring that the pressing actions of the user when operating the first button 108 and the second button 109 are accurately transmitted to the trigger area on the button circuit board 107, thus guaranteeing the stability and reliability of the switching function.

[0156] Optionally, a connecting post is provided on the periphery of the button cavity, and the button bracket 111 is connected to the connecting post of the button cavity through the second fastener 122 to realize the fixed connection between the button bracket 111 and the outer shell 110; after the button circuit board 102 is engaged with the button bracket 111 in a foolproof manner, it is fixedly connected through the second fastener 122.

[0157] In some embodiments, a first elastic structure and a second elastic structure are provided on the seal 112 to enhance the feedback and functionality of button operation. The first button 108 can press the first elastic structure on a first side, causing the second side of the first elastic structure to contact the button circuit board 107; similarly, the second button 109 can press the second elastic structure on a first side, causing the second side of the second elastic structure to contact the button circuit board 107.

[0158] Specifically, the button bracket 111 is provided with through holes, the number and position of which correspond to the first elastic structure and the second elastic structure on the seal 112, so that the first elastic structure and the second elastic structure can pass through the through holes and contact the button circuit board 107.

[0159] Furthermore, one side of the first button 108 serves as a pressing surface, and the other side is provided with a first connecting rod. The end of the first connecting rod can press the first elastic structure on the first side of the first elastic structure. One side of the second button 109 serves as a pressing surface, and the other side is provided with a second connecting rod. The end of the second connecting rod can press the second elastic structure on the first side of the second elastic structure.

[0160] Furthermore, the first elastic element 120 and the second elastic element 121 can be designed as springs, with the springs fitted onto the corresponding connecting rods. The first end of the spring abuts against the second side of the corresponding button (first button 108 or second button 109), and the second end of the spring abuts against the first side of the seal 112. This design allows the buttons to obtain better tactile feedback when pressed, while ensuring the accuracy and reliability of button operation.

[0161] In some embodiments, the seal 112 is provided with two symmetrical semi-circular protrusions, which contact and interfere with the second button 109, thereby limiting the extreme position of the second button 109.

[0162] In one specific embodiment, the installation process of the housing 110 and the two-button switch in the handheld infrared device is described below.

[0163] During installation, the first button 108 is guided into a specific position along the guide groove 1081, followed by the insertion of the first elastic element 120. The second button 109 uses a fulcrum rotation method. Arc-shaped guide protrusions 1092 are provided at both corners of the second button 109, and an arc-shaped guide groove 1104 is provided in the outer shell 110. During installation, the guide protrusions 1092 of the second button 109 are placed into the guide groove 1104 to reach the specific position, followed by the insertion of the second elastic element 121. After the first button 108, the second button 109, and their corresponding elastic elements are in place, the sealing element 112 is installed. The sealing element 112 has two semi-circular protrusions that contact and interfere with the second button 109. When installing the button bracket 111, the second fastener 122 is used to fix the button bracket 111 to the outer shell 110, and the sealing element 112 is compressed appropriately. The second button 109 creates a fulcrum between the outer shell 110 and the sealing element 112, allowing the second button 109 to rotate only around the fulcrum. The first button 108 and the second button 109 operate on different principles and will not interfere with each other structurally. The seal 112 is appropriately compressed against the outer casing 110, ensuring that the first button 108, the second button 109, the elastic element, and other components are located outside the outer casing 110, while the button circuit board 107 is located inside the outer casing 110, effectively creating a waterproof function. The button circuit board 107 is fixed to the button bracket 111 using a second fastener 122. Asymmetrical protrusions are provided on the surface of the button bracket 111, forming a foolproof design with the button circuit board 107. The first button 108 and the second button 109 are positioned close to each other on the outer casing 110, similar to trigger operation, making user operation more convenient.

[0164] In some embodiments, the main body 1 of the device is provided with a laser module 113, which is electrically connected to the functional circuit board 102.

[0165] In this embodiment, the main body 1 of the device integrates a laser module 113, a design that expands the functionality of the handheld infrared device. The laser module 113 can measure the distance to a target object by emitting a laser beam and transmit the measurement results to the functional circuit board 102 for processing. Simultaneously, the module also has an indicating function, emitting a laser beam to indicate the target position, which is crucial for improving the device's positioning accuracy and ease of operation. Through electrical connection with the functional circuit board 102, the data from the laser module 113 can be effectively integrated and processed, making the device more efficient and accurate in performing tasks. This integrated design not only enhances the device's practicality but also provides convenience for users in various application scenarios.

[0166] Please refer to Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of a handheld infrared device provided in an embodiment of this application from a fourth viewing angle. Figure 11 This is a schematic diagram of the back cover provided in an embodiment of this application.

[0167] In one specific embodiment, the outer shell 110 includes a front shell 1101 and a rear shell 1102, which together constitute the outer shell 110.

[0168] Specifically, based on the front shell 1101, an infrared detection module 101, a functional circuit board 102, a data interface 103, a fixing bracket 105, a board bracket 106, a button circuit board 107, a first button 108, a second button 109, a button bracket 111, a sealing component 112, a laser module 113, and a battery are installed. Based on the rear shell 1102, a mounting base 104 and a heat sink 115 are installed.

[0169] On the outer side of the front housing 1101, next to the lens 3, there are laser ranging windows 117 and laser pointing windows 118, corresponding to the positions of the laser module 113 on the inner side of the front housing 1101. Laser ranging is achieved through the laser ranging window 117, allowing users to quickly determine the distance to the object being measured. This is especially important when facing high-voltage power equipment, ensuring users maintain a safe distance and protecting personnel safety. Laser pointing is achieved through the laser pointing window 118. Factory calibration ensures that the laser pointing point coincides with the marked point on the screen, allowing users to quickly determine the position of the object being measured. Simultaneously, the laser pointing function also facilitates quick identification of the same object by the user and their companions.

[0170] On the outside of the front housing 1101, below the lens 3, there is a lens protective cover 116. The lens protective cover 116 is fixed to the front housing 1101 in a way similar to the spring bar of a watch strap, which is simple and effective. The lens cover 116 can protect the lens 3 from damage during storage and prevent strong light from burning the detector.

[0171] On the outside of the rear cover 1102, there is also a power indicator light 119 on the lower side of the device bracket 2. The power indicator light 119 faces the user and is electrically connected to the functional circuit board 102. By different numbers of lights, the user can quickly judge the power status of the device and thus understand the battery usage of the device in a timely manner.

[0172] A heat sink 123 is embedded inside the rear housing 1102. When the rear housing 1102 is installed with the front housing 1101, the heat sink 123 contacts the functional circuit board 102, transferring the heat generated by the functional circuit board 102 to the rear housing 1102, reducing heat radiation to the detector section, thereby improving the accuracy and stabilization time of temperature measurement. This design helps maintain the high performance and reliability of the equipment under long-term use or high-intensity working environments.

[0173] The bottom of the casing 110 has a charging port 125, which can use a Type-C port and can charge the entire device using a standard data cable. In addition, the bottom also has a mechanical interface 124, which can use a 1 / 4-inch imperial expansion interface, allowing users to expand the device as needed, such as mounting it on a tripod for long-term testing.

[0174] This application describes an innovative handheld infrared device designed to hold a smartphone and display a thermal image on the phone's screen. This device integrates advanced autofocus, enabling rapid focus adjustment to obtain a clear image regardless of the target object's distance. Furthermore, it features a ranging function, allowing users to measure the precise distance to the object being measured, which is particularly important in applications requiring safe distances, such as the inspection of high-voltage power equipment. The device also includes a laser pointing function, helping users accurately locate the target and confirm its position on the smartphone screen. These integrated features make this handheld infrared device widely applicable in various industrial inspection and measurement applications, while improving ease of operation and efficiency.
