Description

Technical Field

[0001] This utility model relates to the field of safety detection equipment technology, and further to an integrated terahertz detection device. Background Technology

[0002] The terahertz (THz, 1 THz = 10¹² Hz) band refers to the electromagnetic radiation range with frequencies from 0.1 THz to 10 THz and wavelengths between microwaves and infrared light. Due to its short timescale, terahertz radiation can provide ultrafast time-resolved spectroscopy, allowing it to penetrate biological materials, dielectric materials, and gaseous substances. By analyzing the transmitted and reflected terahertz signals of a sample, information about the material's composition, physical, chemical, and biological states can be obtained. Furthermore, because terahertz waves have a wide frequency band and low photon energy, they do not damage the detected material, making terahertz technology applicable to many fields such as imaging, spectral analysis, non-destructive testing, and high-speed wireless communication.

[0003] Traditional probes typically lack any display functionality, only transmitting / receiving terahertz wave signals. Operators must transmit the raw signal data acquired by the probe to an external, separate display device via cable. This method results in a significant delay from acquisition to obtaining the final analysis results, making it impossible to obtain intelligent diagnostic conclusions on-site. This reliance on external display devices severely limits the portability of the probe and the flexibility of on-site operation. Especially in situations requiring probe movement for scanning (such as large component inspection, security inspection, equipment inspection) or in space-constrained environments (such as confined spaces or high-altitude operations), operators must simultaneously carry and operate both the probe and the display device, and may even require additional assistants to view the data, leading to inefficiency and a high risk of errors. Operators cannot see the test results (waveforms, images, key parameters, etc.) in real time at the probe's operating point; they must frequently turn their heads or move to the display device to view them, disrupting the continuity of the testing process and reducing testing efficiency and user experience.

[0004] Traditional probes often only have simple physical switches and lack a direct human-machine interface. Operations such as adjusting detection parameters, switching detection modes, and storing / retrieving data must be completed through the software interface on a connected external computer or control box. Operators need to be familiar with the dedicated software on the external device, which increases the learning cost and operational complexity, hindering quick mastery and efficient on-site operation. The working status of the probe itself cannot be directly obtained at the probe end and requires reliance on external devices or indicator lights. At the same time, complex cable connections increase the complexity of system deployment, are prone to tangling, and affect operational convenience and safety.

[0005] Therefore, it is necessary to design an integrated terahertz detection device to solve the above problems. Utility Model Content

Detailed Implementation

[0044] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0045] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0046] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0047] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] In one embodiment, refer to the appendix to the specification. Figures 1 to 5The present invention provides an integrated terahertz detection device, comprising: a base plate 1, a housing 2, a probe assembly 3, a processing module, and a touch screen 4; the housing 2 is slidably mounted on the base plate 1, and a detection port 21 for terahertz wave transmission and reception is provided at the bottom of the housing 2; the probe assembly 3 is integrated into the housing 2 and is correspondingly arranged with the detection port 21, and the probe assembly 3 is used to generate and receive terahertz wave signals; the processing module is disposed in the housing 2 and connected to the probe assembly 3, and the processing module is used to process the terahertz signals collected by the probe assembly 3 in real time; the touch screen 4 is disposed in the housing 2 and connected to the processing module, and the touch screen 4 is used to receive user input to adjust detection parameters, control the detection process, and display detection results in real time.

[0050] In this embodiment, by integrating the probe assembly 3, processing module, and touch display screen 4 into a sliding housing 2, a highly integrated and compact design of the detection device is achieved, significantly improving the portability and operational flexibility of the equipment. The integrated structural design organically combines the functional modules of terahertz wave transmission, reception, signal processing, and result display, eliminating the signal transmission delay problem present in traditional separate devices and enabling real-time visualization of the detection results. The direct control function of the touch display screen 4 simplifies the operation process, allowing users to quickly adjust parameters and obtain results on-site, significantly improving detection efficiency.

[0051] In addition, the sliding housing 2 design allows the probe assembly 3 to move smoothly, ensuring the stability of the detection process and the continuity of data acquisition; the overall device structure is reasonable, which not only meets the strict accuracy requirements of terahertz detection, but also optimizes the human-computer interaction experience, making it particularly suitable for application scenarios that require mobile detection or rapid on-site diagnosis.

[0052] In one embodiment, refer to the appendix to the specification. Figure 2 A translation component 5 is mounted on the base plate 1, arranged along the length of the base plate 1. The housing 2 is mounted on the translation component 5, allowing the housing 2 to reciprocate along the length of the base plate 1. The base plate 1 serves as the physical foundation and structural framework of the entire device, providing the necessary mechanical strength and rigidity to prevent deformation or displacement. During use, the base plate 1 is pressed against the object under test; that is, the terahertz wave signal emitted by the probe component 3 needs to pass through the base plate 1 to irradiate the surface of the object under test. The base plate 1 can be made of high-density polyethylene (HDPE), polytetrafluoroethylene (PTFE) composite material, or a multi-layer composite structure. The base plate 1 must ensure excellent terahertz wave transmission characteristics within the device's operating frequency band while meeting mechanical support requirements. In specific implementations, the most suitable material combination for the particular application scenario can be selected.

[0053] Further, refer to the attached instruction manual. Figure 2The translation component 5 includes a guide rail 51 and a slider 52. The guide rail 51 is mounted on the base plate 1 and arranged along the length of the base plate 1. The slider 52 is adapted to the guide rail 51 and can reciprocate along the length of the guide rail 51. The guide rail 51 provides a high-precision, low-friction linear motion path for the probe assembly 3. The rigid structure and pre-tightening device of the guide rail 51 can suppress vibration, swaying, or axial movement during movement, ensuring the stability of the probe posture. The slider 52, as a moving platform, directly supports the housing 2 and its integrated probe assembly 3 and touch display screen 4, and performs precise linear reciprocating motion along the track direction of the guide rail 51. The slider 52 adopts a low friction coefficient design to ensure smooth and stable movement on the guide rail 51 without jamming or vibration. This stability is crucial for the accurate transmission and reception of terahertz waves and for avoiding motion artifacts that interfere with the detection signal. At the same time, the slider 52 has a high rigidity structure, which can effectively resist the small reaction forces or external disturbances during probe operation, ensuring the stability of the detection process. Of course, translation component 5 can also employ other structures or devices with translation functions.

[0054] Further, refer to the attached instruction manual. Figure 1 The integrated terahertz detection device also includes a support frame 22, which is fixedly installed at the bottom of the housing 2. A hollow structure 221 is provided in the middle of the support frame 22. The support frame 22 is used to fix the core functional module. It is made of high-strength material with low thermal expansion coefficient, providing sufficient structural rigidity to resist minor deformation or external stress during handheld operation and prevent displacement of internal optical path or electronic components due to deformation.

[0055] At least two guide rails 51 are provided, arranged in parallel and spaced apart. Each guide rail 51 has at least one slider 52, and the support frame 22 is connected to the corresponding slider 52. The detection port 21, the hollow structure 221, and the gap between the guide rails 51 are coaxially arranged to form a continuous terahertz wave transmission channel, so that the terahertz waves emitted by the probe assembly 3 can penetrate the transmission channel without obstruction and irradiate the surface of the object under test.

[0056] In this embodiment, an unobstructed terahertz wave transmission channel is constructed through the coaxial layout of the hollow structure 221 and the gap between the guide rail 51, ensuring signal integrity; the parallel double guide rails and multi-point slider connection significantly improve the stability and anti-deflection capability of the housing 2 movement; while ensuring mechanical strength, the overall structure perfectly solves the technical contradiction of signal path obstruction and movement stability in traditional designs, making it particularly suitable for high-precision terahertz scanning detection applications.

[0057] In one embodiment, refer to the appendix to the specification. Figure 3 , Figure 4The housing 2 is equipped with a rotating component 23, through which the touch screen 4 is mounted, allowing for adjustable orientation. The housing 2 provides a stable mounting base and protective frame for the touch screen 4, ensuring it will not loosen, shift, or be damaged during operation and movement. It protects the internal, delicate, and expensive electronic components and optical elements from external physical shocks, vibrations, dust, liquids, foreign object intrusion, and accidental collisions during operation. Terahertz images, waveforms, spectra, or numerical results captured by the probe assembly 3 are displayed directly on the touch screen 4 in real time. Operators can immediately view the testing results on-site without connecting to an external computer or relying on bulky display devices. Operators can make preliminary interpretations of the results immediately on-site, determining whether there are abnormalities inside the tested object (such as defects, foreign objects, delamination), whether the structure is intact, and whether the material properties meet requirements, achieving real-time on-site feedback and greatly accelerating the testing process and decision-making speed.

[0058] Specifically, the rotating component 23 includes a first base 231, a rotating shaft 232, and a second base 233. The first base 231 is fixed to the top of the housing 2, and the second base 233 is fixed to the back of the touch screen 4. The first base 231 and the second base 233 are rotatably connected via the rotating shaft. This structure enables flexible multi-angle adjustment of the touch screen 4, allowing the operator to freely adjust the screen orientation according to the detection posture and viewing angle requirements. The rotating shaft connection method ensures structural stability while providing a smooth rotation experience, ensuring the best viewing angle in various working environments.

[0059] Furthermore, the first base 231 is provided with a first cable channel 2311, which communicates with the interior of the housing 2; the second base 233 is provided with a second cable channel 2331, which is located at the cable interface of the touch display screen 4; a damping element is provided on the pivot 232, which is used to allow the touch display screen 4 to hover at different angles. By setting up cable channels, the cable routing of the display screen is concealed, effectively avoiding cable tangling that affects operation; the damping pivot structure allows the touch display screen 4 to hover stably at any angle, providing a stepless adjustable feel, ensuring both the flexibility of angle adjustment and the stability of the working state, significantly improving the user experience and reliability of the device.

[0060] In one embodiment, refer to the appendix to the specification. Figure 5The probe assembly 3 includes a terahertz transmitter 31, a terahertz detector 32, a first reflector 33, a second reflector 34, a third reflector 35, and a fourth reflector 36, all disposed inside the housing 2. The first reflector 33 has a first reflecting surface 331, and the second reflector 34 has a second reflecting surface 341. The first reflecting surface 331 is set at a preset angle to the optical axis of the terahertz transmitter 31, and the second reflecting surface 341 is arranged opposite to the first reflecting surface 331. The third reflector 35 has a third reflecting surface 351, and the fourth reflector 36 has a fourth reflecting surface 361. The fourth reflecting surface 361 is set at a preset angle to the detection port 21, and the third reflecting surface 351 is arranged opposite to the fourth reflecting surface 361. The first reflector 33 and the second reflector 34 constitute a transmission optical path system. The terahertz wave generated by the terahertz transmitter 31 is reflected sequentially by the first reflecting surface 331 and the second reflecting surface 341, and then emitted vertically downwards from the detection port 21. The third reflector 35 and the fourth reflector 36 constitute a receiving optical path system. The terahertz wave reflected from the object under test is incident through the detection port 21, and is reflected by the fourth reflector 361 and the third reflector 351 in sequence before being incident vertically to the receiving end of the terahertz detector 32.

[0061] In this embodiment, the precise angular arrangement of four reflective surfaces enables efficient transmission and reception of terahertz waves within a limited space. The transmitting optical path converts the terahertz waves into a vertically downward output, while the receiving optical path accurately guides the reflected signal into the detector. This compact optical path structure ensures signal transmission quality while significantly reducing the probe size, enabling the overall device to achieve miniaturization while maintaining high performance.

[0062] It should be noted that the specific structure of the probe assembly 3 is described with reference to the accompanying drawings in the specification. In actual use, the probe assembly 3 can be set to other structures according to actual needs, as long as the above functions can be achieved. This is only for better illustration of the present invention and should not constitute a limitation on the present invention.

[0063] In one embodiment, refer to the appendix to the specification. Figure 3 The integrated terahertz detection device also includes handles 24, which are located on both sides of the housing 2. The handles 24 are used to adjust the position of the housing 2. The shape of the handles 24 conforms to the natural grip curve of the palm and has finger grooves, which can closely fit the operator's hand shape, reduce fatigue caused by long-term operation. The position design of the handles 24 helps to balance the overall center of gravity of the probe, so that the weight of the device is more evenly distributed on the hand, reducing the burden of operation and improving the sense of control.

[0064] Further, refer to the attached instruction manual. Figure 2The integrated terahertz detection device also includes a handle 11, which is located at both ends of the base plate 1. The handle 11 is used to move the entire device. The handle 11 provides the operator with an intuitive and stable grip point, making it easy to lift, move and carry the entire integrated probe device with both hands. It is suitable for scenarios that require frequent movement between different detection points, solving the problem of inconvenient movement of traditional benchtop or bulky probes and greatly improving detection efficiency.

[0065] In this invention, the previously separate terahertz probe is structurally integrated with a small intelligent display screen, forming a single, compact handheld device. While acquiring terahertz signals, the probe simultaneously displays the processed waveforms, spectra, image previews, and defect markings on the integrated screen in real time. The operator can immediately see the test results without looking away or searching for an external display, eliminating the need to export data to an external device for later viewing, thus greatly improving testing efficiency. The integrated touchscreen and physical buttons allow the operator to perform basic control operations directly on the probe, such as starting / stopping scanning, adjusting parameters (gain, frequency range, etc.), selecting display modes, marking regions of interest, saving data, and switching test modes. The display screen's position minimizes, or even eliminates, the operator's eye movement when observing the target and viewing the screen, reducing operator fatigue. By optimizing the overall structural layout, the display screen is positioned and angled for easy observation while ensuring convenient grip and operation of the probe. The probe features a rotatable and omnidirectionally adjustable screen design to adapt to different detection postures. It also integrates data processing capabilities to preprocess the raw terahertz signal and generate simplified results that can be directly displayed on the screen.

[0066] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0067] It should be noted that the above embodiments can be freely combined as needed. The above are only optional embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
