Description

Technical Field

[0001] This application relates to the field of thermal imagers, and more particularly to mobile phone plug-in thermal imagers. Background Technology

[0002] With the widespread use of mobile electronic devices, thermal imagers, as mobile phone accessories, are increasingly used in equipment maintenance, scientific research observation, and home testing due to their portability and flexibility. These devices are typically equipped with a standard infrared lens, which can meet the needs of capturing macroscopic temperature distribution in most common scenarios. However, when dealing with thermal analysis of tiny objects and details that require high spatial resolution, the imaging resolution of a standard lens is insufficient to clearly present the temperature details of microscopic targets. Therefore, the industry's common solution is to equip the thermal imager with a separate macro lens module as a functional accessory. By mounting this module in front of the main lens, close-range, high-resolution thermal imaging of tiny targets can be achieved.

[0003] Currently, the main methods for connecting such macro modules to the thermal imager body include threaded connections and snap-fit ​​fastening. These existing connection solutions have obvious drawbacks in practice: First, they are not convenient to install. Threaded connections require multiple rotations for alignment, and snap-fit ​​connections require finding a specific angle and applying precise pressure, making the operation cumbersome and unable to achieve quick assembly and disassembly.

[0004] Therefore, a mobile phone plug-in imaging device that can achieve stable connection and quick assembly / disassembly is needed. Utility Model Content

[0020] Embodiments of this application provide a mobile phone plug-in thermal imager, including: a body, a macro component, a first magnet, and a second magnet. A placement cavity is formed inside the body. The macro component is magnetically attached to the body to acquire macro thermal images for analysis. The first magnet is mounted on the body, located within the placement cavity, and abuts the opposite surface of the body and the macro component. The second magnet is mounted on the macro component and magnetically attracted to the first magnet, with the first and second magnets facing each other.

[0021] The aforementioned mobile phone plug-in thermal imager achieves rapid assembly / disassembly and stable connection by embedding the first and second magnets respectively within the main body and the macro component, with precise alignment. Utilizing the magnets' automatic adsorption properties, the macro component instantly attaches without manual alignment upon approach, enabling one-click installation and disassembly. Furthermore, the magnets' internal structure and aligned design not only concentrate the magnetic force and strengthen the connection, preventing accidental detachment or displacement of accessories, but also ensure automatic alignment of the optical axis of the macro component and the main body lens through the self-guiding effect of the magnetic force. This provides convenient operation while guaranteeing structural stability and imaging accuracy.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please see Figures 1-5 This application provides a mobile phone plug-in thermal imager 100, including: a body 10, a macro element 20, a first magnet 30, and a second magnet 40. The body 10 has a placement cavity 11. The macro element 20 is magnetically attached to the body 10 to obtain macro thermal images for analysis. The first magnet 30 is mounted on the body 10, located within the placement cavity 11, and adheres to the opposite surface of the body 10 where the macro element 20 is attached. The second magnet 40 is mounted on the macro element 20 and magnetically attracted to the first magnet 30, with the first magnet 30 and the second magnet 40 facing each other.

[0024] The main body 10 is the main structural part of the mobile phone plug-in thermal imager 100. It has an internal placement cavity 11 for accommodating and supporting the macro component 20. This ensures that the macro component 20 fits tightly with the main body 10 during installation and provides stable support to guarantee the stability of the imager.

[0025] The macro element 20 is magnetically attached to the body 10 and is primarily used for macro thermal imaging analysis. Designed as a high spatial resolution lens module 50, the macro element 20 enables close-range, high-precision thermal imaging of minute targets. The magnetic connection between the macro element 20 and the body 10 not only ensures the stability of the device but also allows the macro element 20 to quickly and accurately attach when brought close together through magnetic self-guidance. Furthermore, the magnetic attraction between the macro element 20 and the body 10 prevents displacement or detachment due to external forces, thus guaranteeing the stability and accuracy of the imaging.

[0026] The first magnet 30 is installed in the placement cavity 11 within the main body 10, located on the opposite side of the micro-part 20. The function of the first magnet 30 is to provide a strong magnetic force, ensuring that the micro-part 20 can be firmly attached to the main body 10. The second magnet 40 is installed inside the micro-part 20 and attracts the first magnet 30 through magnetic attraction, further enhancing the connection's strength. The facing arrangement of the first magnet 30 and the second magnet 40 concentrates the magnetic attraction between the micro-part 20 and the main body 10, ensuring precise alignment and preventing displacement due to uneven magnetic force.

[0027] In one specific embodiment, the body 10 of the mobile phone plug-in thermal imager 100 is formed by a bottom cover 12 and a housing 13, and an internal placement cavity 11 is provided. This design mainly uses the tight fit between the bottom cover 12 and the housing 13 to form the placement cavity 11, providing a stable mounting position for the macro component 20. The structure of the bottom cover 12 and the housing 13 not only provides support, but also ensures a stable connection between the macro component 20 and the body 10 through a tight fit. In this embodiment, the size of the placement cavity 11 matches the size of the macro component 20, ensuring that the macro component 20 can be stably installed and easily disassembled, and is not prone to loosening or falling off.

[0028] The connection between the housing 13 and the macro component 20 is a magnetic attachment. Specifically, the macro component 20 and the housing 13 are securely connected by the magnetic attraction of magnets. The first magnet 30 is installed inside the housing 13 of the main body 10, while the second magnet 40 is installed inside the macro component 20. Through the interaction of magnetic forces, the macro component 20 is firmly fixed to the housing 13. The advantage of magnetic attachment is that it not only achieves a stable connection but also makes the docking of the macro component 20 and the housing 13 very simple. The user only needs to bring the macro component 20 close to the housing 13, and it will automatically be attracted into place without cumbersome operations or manual alignment.

[0029] Furthermore, due to the magnet design, the magnetic attraction between the macro element 20 and the housing 13 is relatively concentrated, ensuring a firm connection. Simultaneously, the magnetic self-guiding effect allows the optical axis of the macro element 20 to automatically align with that of the body 10, avoiding imaging errors that may result from manual adjustment. Therefore, during use, the connection stability and accuracy between the macro element 20 and the body 10 are guaranteed, making it particularly suitable for thermal imaging analysis of tiny objects requiring high-precision imaging.

[0030] In one specific embodiment, the housing 13 has a placement slot 131 and a lens slot 132 adjacent to the placement slot 131. This design forms two slot structures inside the housing 13, with the placement slot 131 clamping the lens slot 132, thereby providing a stable and precise positioning position for the lens 50. Specifically, the shape and size of the placement slot 131 match the first magnet 30, ensuring that the lens 50 can be fixed in the lens slot 132 during installation without any displacement or loosening. This structure effectively and firmly fixes the lens 50 inside the housing 13 and ensures that the lens 50 is aligned with the optical axis of the thermal imager, thereby guaranteeing the clarity and accuracy of the thermal imager's imaging.

[0031] Furthermore, the first magnet 30 is located within the placement groove 131. The specific position of the first magnet 30 within the placement groove 131 serves to strengthen the connection and provide positioning. By installing the first magnet 30 within the placement groove 131, magnetic force can be used to ensure a secure connection between the micro-part 20 and the housing 13 of the body 10. When the micro-part 20 approaches the housing 13, the first magnet 30 attracts the second magnet 40, thus stably fixing the micro-part 20 to the housing 13. The arrangement of the first magnet 30 creates an automatic guiding mechanism between the magnetic connection and the housing 13, ensuring precise alignment and stable installation of the micro-part 20 and the body 10. Specifically, this magnet design enhances the stability of the connection, preventing loosening due to external forces or vibrations.

[0032] The beneficial effect of this structural design is that the placement slot 131 and lens slot 132 effectively improve the positioning accuracy of the lens 50, allowing the lens 50 to be accurately fixed inside the thermal imager and avoiding deviations during installation. The design of the first magnet 30, while ensuring stable installation of the lens 50, utilizes the magnetic attraction properties to allow the macro component 20 to be quickly and stably installed on the housing 13. Compared to traditional threaded connections or snap-fit ​​fixing methods, this magnetic design not only simplifies the operation process but also improves ease of use.

[0033] In one specific embodiment, the imager includes a lens 50, which is placed within a lens slot 132 and disposed adjacent to a first magnet 30. The lens 50 is a key component of the mobile phone plug-in thermal imager 100, its main function being to convert thermal radiation signals into image signals, thereby achieving thermal imaging. The design of the lens slot 132 ensures that the lens 50 can be securely mounted within the housing 13 and maintain precise alignment to ensure image quality.

[0034] The internal structure of the lens slot 132 matches the shape of the lens 50, allowing the lens 50 to be securely installed and preventing loosening or displacement during use. The design of the lens slot 132 not only ensures the stability of the lens 50 but also guarantees the coordinated operation of the lens 50 with other internal components of the thermal imager, avoiding imaging errors or image distortion.

[0035] Furthermore, the lens 50 is positioned adjacent to the first magnet 30. The first magnet 30 is located within the lens slot 132, and its function is to provide magnetic attraction, making the connection between the macro component 20 and the housing 13 of the body 10 more secure. This magnetic design simplifies the installation process of the lens 50. When the macro component 20 approaches the body 10, the magnetic force generated by the magnet quickly attracts it into place and automatically aligns it, ensuring precise alignment between the lens 50 and the optical axis of the imager. This design allows the thermal imager to achieve both high precision and ease of operation during use.

[0036] In one specific embodiment, the housing 13 includes a magnetic surface 133, which is integrally formed with the placement groove 131 and the lens groove 132 and is located on the side opposite to the placement groove 131 and the lens groove 132. The function of the magnetic surface 133 is to provide an effective magnetic attraction area for the housing 13, ensuring a more secure magnetic connection with the macro component 20 and enhancing the stability of the thermal imager during use.

[0037] The magnetic surface 133 is positioned away from the placement slot 131 and lens slot 132. This arrangement effectively prevents interference between the magnetic surface 133 and other internal structures, and ensures that the magnetic force is concentrated on the connection between the macro component 20 and the housing 13. By placing the magnetic surface 133 on one side of the housing 13, this surface can exert maximum magnetic force, allowing the macro component 20 to quickly attract and fix itself when it approaches the housing 13, ensuring a stable connection of the imaging device components and preventing loosening caused by external forces or vibrations.

[0038] Specifically, the magnetic surface 133 is integrally formed with the placement slot 131 and the lens slot 132. This design makes the magnetic surface 133 a part of the housing 13, enhancing its overall structural integrity and avoiding gap problems that may arise from connecting multiple components. The other structures within the housing 13, such as the placement slot 131 and the lens slot 132, are also designed to cooperate with the magnetic surface 133, making the installation process simpler and faster, while ensuring precise alignment and stable fixation of each component.

[0039] During operation, the user simply needs to bring the macro component 20 close to the housing 13, and the magnetic surface 133 will attract the macro component 20, thus completing the installation of the lens 50 assembly. This process eliminates the need for manual alignment or adjustment, greatly simplifying operation and improving the convenience of the device. Furthermore, the one-piece molding design of the magnetic surface 133 not only optimizes the transmission efficiency of magnetic force but also improves the structural strength of the entire housing 13, enhancing the device's resistance to vibration and interference.

[0040] In one specific embodiment, the macro component 20 further includes a bonding portion 21 and a macro module 22. The bonding portion 21 serves to tightly bond the macro component 20 to the housing 13, ensuring that the macro component 20 is stably fixed after installation and does not loosen or shift. Specifically, the bonding portion 21 makes close contact with the surface of the housing 13, forming a stable connection area. This design prevents the macro component 20 from shifting due to external forces or vibrations during use. Through the tight fit with the housing 13, the bonding portion 21 improves the connection stability between the macro component 20 and the thermal imager body 10, ensuring that the macro component 20 can remain in its original position for a long time, providing accurate thermal imaging analysis.

[0041] The macro module 22 is installed within the fitting part 21 and is attached to the lens 50. The main function of the macro module 22 is to provide high-resolution thermal imaging capabilities for analyzing minute objects and details. When the macro module 22 is tightly fitted with the lens 50, it ensures that the image quality meets the required precision, making it particularly suitable for high-precision analysis of heat distribution in small objects or tiny areas. The design of the macro module 22 not only improves the resolution of the thermal imager but also ensures image clarity and accuracy through direct docking with the lens 50. This design allows users to perform detailed microscopic thermal imaging analysis, suitable for applications requiring high-precision analysis such as equipment maintenance and scientific observation.

[0042] Furthermore, the close fit between the macro module 22 and the lens 50 enables efficient collaboration among the various components of the optical system, ensuring automatic alignment of the thermal imager's optical axis and avoiding the inaccuracies and operational complexities associated with manual alignment. The precise cooperation between the macro module 22 and the lens 50 allows the device to provide stable image quality during thermal imaging, adapting to various working environments.

[0043] In one specific embodiment, the second magnet 40 is located within the bonding portion 21 and distributed circumferentially along the macro module 22. The function of the second magnet 40 is to further enhance the magnetic attraction between the macro component 20 and the housing 13, ensuring that the macro component 20 can be stably fixed to the body 10 after installation. By placing the second magnet 40 within the bonding portion 21, the fixation of the macro component 20 is more secure, while preventing loosening or displacement of the macro component 20 due to vibration or external forces during use.

[0044] Specifically, the second magnets 40 can be evenly spaced or unevenly spaced along the circumference of the micro module 22. The even distribution of the second magnets 40 along the circumference of the micro module 22 ensures that the magnetic force is uniformly transmitted between all parts of the micro component 20. This uniform distribution design allows the micro component 20 to quickly and evenly adhere to the housing 13 when it approaches, thus avoiding skewed or asymmetrical adhesion and ensuring precise docking and a firm connection between the micro component 20 and the body 10. This design ensures the concentrated effect of the magnetic force while avoiding its unevenness, which is crucial for maintaining the stability of the thermal imager.

[0045] Furthermore, the circumferential distribution of the second magnet 40 along the macro module 22 provides a balanced adsorption force during the contact between the macro component 20 and the housing 13, avoiding assembly difficulties or uneven connections caused by excessive local adsorption. This design helps improve the docking accuracy between the macro component 20 and the housing 13 of the body 10, and further ensures the stability of the thermal imager's imaging system, especially in high-resolution imaging, avoiding image distortion or errors caused by component instability.

[0046] In one specific embodiment, the first magnet 30 is distributed circumferentially along the lens 50.

[0047] In this design, the first magnet 30 and the second magnet 40 are attracted to each other. Their positions can be evenly spaced or unevenly spaced along the circumference of the lens 50. The even distribution of the first magnet 30 around the lens 50 ensures that the magnetic attraction force acts uniformly around the lens 50, thereby guaranteeing a stable connection between the macro component 20 and the housing 13 of the body 10. The even distribution of the first magnet 30 around the lens 50 avoids situations where the local magnetic attraction force is too strong or too weak, thus preventing uneven attraction and ensuring a more precise alignment between the macro component 20 and the lens slot 132. This design allows the macro component 20 to align more smoothly with the housing 13 during installation, thereby improving the overall assembly accuracy.

[0048] The design of the first magnet 30 distributed circumferentially along the lens 50 provides additional stability, especially during the use of the thermal imager. External forces or vibrations may affect the stability of the macro element 20, and the uniformly distributed magnets effectively prevent the macro element 20 from shifting or loosening. This design allows the thermal imager to maintain optical alignment between the lens 50 and the macro element 20 during high-precision thermal imaging analysis, ensuring that image quality is not affected.

[0049] Furthermore, the uniform distribution of the first magnets 30 ensures a stable connection between the micro-parts 20 and the housing 13 when they come into contact through the self-guiding effect of magnetic force. Each time they are installed, the magnetic force evenly attracts the micro-parts 20 into place, avoiding the inaccurate alignment and weak connection that may occur with traditional threaded or snap-fit ​​connections. This design simplifies the installation process and ensures the stability of the micro-parts 20 during use.

[0050] In one specific embodiment, the two first magnets 30 are symmetrically arranged with respect to the lens 50, and the two second magnets 40 are symmetrically arranged with respect to the macro module 22. This design, through the symmetrical arrangement of the magnets, ensures the stability and accuracy of the connection between the macro component 20 and the housing 13, further enhancing the ease of operation and imaging quality of the thermal imager.

[0051] The symmetrical arrangement of the first magnet 30 relative to the lens 50 ensures a uniform distribution of magnetic attraction. By evenly distributing the first magnet 30 around the lens 50 and symmetrically arranging it relative to the lens 50, when the macro component 20 approaches the body 10, the magnetic force can act evenly on each side of the macro component 20, allowing the macro component 20 to quickly and accurately align with the housing 13. This design avoids the problem of uneven magnetic force alignment, ensuring automatic alignment of the optical axes of the lens 50 and the macro component 20, thereby guaranteeing the accuracy of the imaging system and the stability of image quality.

[0052] Similarly, the second magnet 40 is symmetrically arranged relative to the macro module 22, allowing the macro module 22 to be stably attracted and fixed to the body 10 during installation. The symmetrical arrangement of the second magnet 40 ensures a more secure connection between the macro component 20 and the housing 13, avoiding installation imbalance or misalignment caused by uneven magnetic force or excessively strong unilateral attraction. Through this design, the macro component 20 can be quickly and accurately installed within the lens slot 132, while ensuring that the connection with the body 10 housing 13 is not disturbed by external forces or vibrations.

[0053] In one specific embodiment, the second magnet 40 is located at one end near the magnetic surface 133. The main function of this design is to ensure the stability and accuracy of the connection between the micro-part 20 and the body 10. The installation position of the second magnet 40 close to the magnetic surface 133 utilizes the concentrated effect of magnetic force to enable the micro-part 20 to quickly and firmly attract and dock with the housing 13.

[0054] Specifically, the second magnet 40 is located at one end of the magnetic surface 133, ensuring that the micro-part 20 can be automatically attracted into place by magnetic force when it approaches the housing 13. The cooperation between the magnetic surface 133 and the second magnet 40 allows the micro-part 20 to be precisely attracted to the body 10 and ensures the firmness of the connection point. This design makes the operation process simpler and more efficient each time the micro-part 20 is installed, while avoiding loose connections or misalignment caused by improper installation or uneven magnetic force.

[0055] The second magnet 40 not only enhances the connection between the macro component 20 and the body 10, but also optimizes the adsorption accuracy through its proximity to the magnetic surface 133. Furthermore, this design enables the macro component 20 to maintain stable alignment during rapid installation, providing a convenient operating method, especially in applications requiring frequent lens 50 changes.

[0056] Therefore, the aforementioned mobile phone plug-in thermal imager 100 achieves rapid assembly and disassembly and stable connection by embedding the first magnet 30 and the second magnet 40 into the main body 10 and the macro component 20 respectively and setting them precisely aligned. Utilizing the automatic adsorption properties of the magnets, the macro component 20 can be instantly adsorbed into place without manual alignment when close, achieving one-click rapid installation and disassembly. Simultaneously, the magnets' internal structure and aligned design not only concentrate the magnetic force and strengthen the connection, preventing accidental detachment or displacement of the accessory, but also ensure that the optical axis of the macro component 20 and the lens 50 of the main body 10 are automatically aligned through the self-guiding effect of the magnetic force. This provides convenient operation while ensuring structural stability and imaging accuracy.

[0057] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
