Description

Technical Field

[0001] This invention relates to the field of wireless communication sensitivity detection technology, specifically to a wireless communication sensitivity testing device. Background Technology

[0002] Wireless communication sensitivity testing is a key evaluation method for measuring the minimum signal strength that a wireless receiving device (such as a mobile phone or WiFi module) can reliably detect and decode. Its background stems from the rapid development of wireless communication technology, especially the widespread adoption of 5G and the Internet of Things (IoT), which requires devices to maintain stable connections in complex environments (such as urban areas with interference or remote areas). In terms of applications, it is used in product development, quality control, and network optimization to ensure that devices do not drop connections or lose packets under weak signal conditions. Its significance lies in improving communication reliability, reducing user complaints, optimizing spectrum efficiency, and promoting the improvement of industry standards (such as 3GPP), ultimately ensuring a seamless experience for applications such as smart homes and autonomous driving.

[0003] The existing technology has the following shortcomings: The current mainstream wireless communication sensitivity testing devices generally use wireless communication testers as the core component, but their fixed architecture has significant bottlenecks: First, at the hardware level, there is a lack of built-in environmental monitoring units (such as temperature and humidity / electromagnetic interference sensors), which cannot capture and calibrate the disturbance of test environmental variables on signal transmission in real time, resulting in systematic deviations in sensitivity test data, especially in complex electromagnetic environments where the risk of signal drift is aggravated. The design of the equipment fixing mechanism relies too heavily on traditional manual operation, such as external mechanical clamps or brackets, and lacks intelligent processing. When changing the device under test (e.g., a smartphone or IoT module), operators must perform multiple steps, including loosening screws, precise alignment, and mechanical tightening, which takes an average of over 30 seconds and is prone to human error (such as signal coupling misalignment or poor contact). In high-throughput scenarios such as mass production lines, this inefficient process severely drags down overall testing efficiency, making it difficult to meet the industrial demand of processing multiple devices per minute. Furthermore, manual operation increases the uncertainty of test results; for example, uneven clamp pressure may affect antenna signal reception, further reducing data comparability.

[0004] Furthermore, there are structural shortcomings in the coordinated control of core functions. Critical operations such as environmental monitoring and equipment adsorption require additional connection to independent modules (such as external sensor arrays or magnetic devices) or reliance on separate operating procedures (such as manually switching software interfaces or physical buttons). This not only significantly increases operational complexity and the probability of misoperation (such as wiring errors or command delays), but also increases the system failure rate due to the coupling of multiple devices. For example, an external environmental simulation unit may introduce electromagnetic crosstalk, and manual function switching prolongs preparation time, thus increasing maintenance costs by more than 20%. Ultimately, these shortcomings—lack of environmental calibration, inefficient operation, and functional fragmentation—collectively weaken the accuracy (increased signal-to-noise ratio fluctuations), stability (frequent failures), and automation level of the testing system, making it unable to meet the stringent requirements of modern industry for efficient, high-precision, and integrated testing solutions (such as 5G equipment mass production or automotive-grade certification). This not only affects product quality control but also limits the widespread application of testing equipment in smart manufacturing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wireless communication sensitivity testing device that solves the problem of signal test data deviation and drift caused by the lack of a built-in environmental monitoring unit.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wireless communication sensitivity testing device, comprising a cuboid wireless communication tester, a radio frequency interface and a data communication interface disposed on its side wall.

[0007] The bottom end face of the wireless communication tester is embedded with an environmental detection unit, which includes a temperature and humidity sensor and a dust concentration sensor arranged side by side.

[0008] The bottom end face is connected to a rectangular cover plate by a hinge mechanism. The hinge mechanism consists of a connecting block fixed at the bottom, a connecting shaft passing through the connecting block and the cover plate, and a return spring sleeved on the outside of the connecting shaft, so that the cover plate can rotate around the shaft and maintain a closed tendency under the preload of the return spring.

[0009] The inner surface of the cover plate is integrated with an electromagnetic sheet, and a matrix-arranged array of electromagnets is embedded at the bottom of the electromagnetic sheet. Its power supply lead is connected to the main control circuit of the wireless communication tester through a pre-embedded channel inside the cover plate.

[0010] The wireless communication tester has a piezoelectric button on the side wall opposite the grip, which has a spring reset component inside and is connected in series in the power supply circuit of the electromagnet array.

[0011] When the operator holds the handle and rotates the device 90° from its horizontal position, the cover plate automatically springs open to its maximum opening angle under the action of the return spring because it is freed from the pressure of the workbench. This simultaneously exposes and activates the temperature and humidity sensor and the dust concentration sensor. At the same time, the piezoelectric button is triggered to close by the vertical pressure of the workbench, causing the electromagnetic plate to be instantly energized and forming a magnetic adsorption plane.

[0012] In some embodiments, the return spring is a torsion spring, and its preload torque satisfies the following mechanical relationship: When placed horizontally, the pressure on the workbench generated by the weight of the wireless communication tester is greater than the spring force of the torsion spring, causing the cover plate to be tightly attached to the bottom end face. After rotating 90°, the pressure on the worktable returns to zero, and the torsion spring force drives the cover plate to rotate 60°-80° to open, ensuring that the sensor is fully exposed.

[0013] In some embodiments, the triggering structure of the piezoelectric button includes: A compression spring inside the button housing normally lifts the button to the power-off position. After rotating 90°, the bottom of the button contacts the worktable. When the deformation of the compressed spring is ≥2mm, the internal micro switch is triggered, which connects the electromagnetic plate circuit.

[0014] In some embodiments, the activation of the magnetic adsorption function of the electromagnetic sheet and the physical exposure of the sensor constitute a mechanical-electric linkage system, which is strictly synchronized with a single 90° rotation movement with a time delay of <0.5 seconds.

[0015] In some embodiments, the electromagnet array of the electromagnetic sheet is arranged in a 5×5 grid, with a single magnetic pole unit spacing of 20±2mm, which is adapted to the adsorption and positioning of the metal frame of the mobile device, and the maximum adsorption force is ≥3N / unit.

[0016] In some embodiments, the grip is detachably fixed to the side wall of the tester by bolts on both sides, the grip portion is covered with an anti-slip silicone layer, and the grip axis is spatially perpendicular to the connecting shaft axis.

[0017] In some embodiments, the circuit switching logic of the piezoelectric button is linked to the rotation angle: Keep power off when the rotation angle is less than 45°; Continuous power supply when the rotation angle is ≥90°; The power will automatically cut off when the reverse rotation reaches <45°.

[0018] In some embodiments, the soft pads embedded at the four corners of the wireless communication tester are made of polymer cushioning material, 5mm thick, protruding 1mm from the shell surface, forming horizontal anti-slip support points.

[0019] In some embodiments, the cover plate, when unfolded, forms an acute angle with the side wall of the wireless communication tester, and its inner electromagnetic plate adsorption surface is perpendicular to the horizontal plane, forming a vertical equipment loading station.

[0020] Compared with the prior art, the present invention provides a wireless communication sensitivity testing device, which has the following beneficial effects: A wireless communication sensitivity testing device is disclosed. Upon powering on, an indicator light illuminates, signifying standby mode. The device is then rotated 90 degrees by holding the handle (with the cover pressed against the worktable, protecting the temperature, humidity, and dust concentration sensors). This rotates the bottom surface to a sideways position. Upon rotation, the cover automatically springs open due to the release of pressure from the worktable, exposing and activating the temperature, humidity, and dust concentration sensors for real-time environmental monitoring. Simultaneously, a piezoelectric button at the bottom is pressed by the worktable, triggering a circuit via an internal spring assembly. This energizes an electromagnetic plate embedded within the cover, creating an adsorption surface for quickly magnetically securing multiple devices (such as mobile phones). The operator can then connect the device via the RF and data communication interfaces for sensitivity testing. A heat dissipation grille ensures stable heat dissipation. After testing, rotating the device 90 degrees back to a horizontal position restores the cover's pressure, protecting the sensors, and the piezoelectric button pops up, disconnecting the power to the electromagnetic plate. The entire process simultaneously activates the sensors and switches between electromagnetic adsorption functions with a single rotation, improving efficiency and reducing manual intervention. Through the above setup and process, this device, compared to existing wireless communication sensitivity testing devices, achieves significant advantages by intelligently binding the 90-degree rotation of the wireless communication tester with sensor protection / activation and the energization of the electromagnetic adsorption surface. This surpasses existing technologies (such as inefficiency due to fixed structures, lack of environmental monitoring, and cumbersome manual operation). After rotation, the cover automatically pops open under the drive of a return spring, exposing and activating the temperature and humidity sensors and dust concentration sensor. This allows for real-time monitoring of environmental parameters (such as temperature, humidity, and dust), simultaneous calibration of sensitivity test data, improving accuracy by up to 15%, and preventing signal drift. Simultaneously, the piezoelectric button triggers the electromagnetic plate to energize, forming an adsorption surface that quickly and magnetically secures multiple devices (such as mobile phones). The entire system completes the dual-function switching with a single action, reducing manual intervention and avoiding the drawbacks of additional external equipment or complex steps in existing technologies. This enhances the device's multifunctionality, reliability, and ease of maintenance. Attached Figure Description

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Please see Figure 1-7In this embodiment: a wireless communication sensitivity testing device includes a wireless communication tester 1 for detecting wireless communication sensitivity, an RF interface 2 for connecting to a wireless communication device, and a data communication interface 3. A temperature and humidity sensor 14 and a dust concentration sensor 15 for environmental detection are disposed on the bottom end face of the wireless communication tester 1. A cover plate 9 for protecting the temperature and humidity sensor 14 and the dust concentration sensor 15 is rotatably disposed on the bottom of the wireless communication tester 1. The cover plate 9 can rotate and open around the bottom of the wireless communication tester 1. A connecting block 11 for supporting the cover plate 9 and positioning it is also disposed on the bottom of the wireless communication tester 1. A connecting shaft 12 for supporting the rotation of the cover plate 9 is inserted through the end of the connecting block 11 (e.g., ...). Figure 7 As shown), a return spring 13 is sleeved on the outside of the connecting shaft 12 to automatically reset the cover plate 9 (as shown). Figure 5 (as shown) Therefore, when the wireless communication tester 1 is in use, simply push its outer casing and rotate it 90 degrees on the workbench to complete the rotation. After rotation, the original bottom side (where the sensor is located) is adjusted to the side, and the cover 9, after losing the pressure from the workbench and the wireless communication tester 1, is opened by the return spring 13. At this time, the temperature and humidity sensor 14 and the dust concentration sensor 15 directly enter the working state (e.g., Figure 6 As shown in the figure, by associating the rotation of the wireless communication tester 1 itself and the operating mode of the environmental monitoring sensor with the external protection structure, the environmental monitoring unit can quickly change its operating state.

[0027] It should be noted that when the wireless communication tester 1 is not in use, the temperature and humidity sensor 14 and the dust concentration sensor 15 are always at the bottom, while the cover plate 9 is pressed against the end face of the worktable by the pressure of the wireless communication tester 1 itself.

[0028] The wireless communication tester 1 has a rectangular structure, and several sets of soft pads 6 are set at the four corners to protect the body of the wireless communication tester 1.

[0029] A power button 4 for controlling the device switch is also provided on the side of the wireless communication tester 1, and an indicator light 5 for displaying the operating mode is also provided on the side of the wireless communication tester 1.

[0030] A handle 7 is detachably fixed to the side of the wireless communication tester 1 by bolts, which is convenient for the operator to hold. By holding the handle 7, the wireless communication tester 1 can be quickly flipped or lifted and transferred.

[0031] An electromagnetic sheet 10 is provided on the inner side of the cover plate 9. The electromagnetic sheet 10 is used to form an adsorption surface after being energized, thereby realizing the arrangement and adsorption of the device to be tested (such as a mobile phone). An electromagnet array is provided at the bottom of the electromagnetic sheet 10, and is embedded in the cover plate 9 through integrated leads and passes through the wireless communication tester 1.

[0032] A piezoelectric button 16 is set on the other side of the wireless communication tester 1. The piezoelectric button 16 is used to control the energization state of the electromagnet array. When the piezoelectric button 16 is pressed by pressure, the electromagnet array is energized and forms an adsorption surface. A spring assembly is installed inside the piezoelectric button 16. Therefore, the piezoelectric button 16 remains in a non-pressed state when there is no external pressure, meaning the electromagnet array is never energized. This binds the attraction of the electromagnetic plate 10 to the pressing of the piezoelectric button 16. The specific steps for controlling the attraction of the electromagnetic plate 10 are as follows: When the wireless communication tester 1 is stationary and not in use, the piezoelectric button 16 is located at the side of the tester, and the electromagnetic plate 10 is not energized. When the wireless communication tester 1 needs to be used, by rotating the tester, the bottom sensor and cover plate 9 are rotated to the side. At this time, the piezoelectric button 16 is pressed to the bottom, and the piezoelectric button 16 is triggered when pressed, energizing the electromagnetic plate 10 to form an adsorption surface. Thus, the energization of the electromagnetic plate 10 is synchronized with the switching of the sensor's operating state.

[0033] In this embodiment, the device is started via power button 4, and indicator light 5 illuminates to show standby status; then, by holding handle 7, the horizontally placed wireless communication tester 1 (at this time, cover 9 is pressed against the worktable, and temperature and humidity sensor 14 and dust concentration sensor 15 are protected) is rotated 90 degrees, so that the original bottom end face turns to the side; at the moment of rotation, cover 9 automatically pops open due to the disappearance of pressure from the worktable and driven by return spring 13 (as shown). Figure 6 The process exposes and activates the temperature and humidity sensor 14 and the dust concentration sensor 15, putting them into real-time environmental monitoring mode. Simultaneously, the piezoelectric button 16 at the bottom, after rotation, is triggered by the workbench, energizing the electromagnetic plate 10 embedded inside the cover plate 9 via an internal spring assembly. This forms an adsorption surface, allowing for rapid magnetic fixation of multiple devices under test (such as mobile phones). The operator can then connect the devices for sensitivity testing via the RF interface 2 and the data communication interface 3. The heat dissipation grille 8 ensures stable heat dissipation. After testing, the device is rotated 90 degrees in the opposite direction to return to a horizontal position. The cover plate 9 closes under pressure to protect the sensors, and the piezoelectric button 16 pops up to disconnect the power to the electromagnetic plate 10. The entire process simultaneously activates the sensors and switches between electromagnetic adsorption functions with a single rotation, improving efficiency and reducing manual intervention.

[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
