Description

Technical Field

[0001] The utility model relates to the field of switch signal testing equipment, and more particularly to a portable switch signal reliability testing device. Background Art

[0002] With the widespread use of modern electronic devices, switches, as important components for controlling signals, play a vital role in various devices and systems. Signal switches are often used to trigger or control circuit operations, and their performance stability is directly related to the reliability and service life of the equipment. Therefore, reliability testing of signal switches, especially long-term pressure testing, is an important means to ensure their quality and durability. However, traditional switch signal reliability testing equipment often has the following shortcomings:

[0003] 1. The test equipment is bulky and difficult to carry: Existing test equipment is often complex and bulky, making it difficult to flexibly apply to different scenarios, especially when on-site testing is required. This limitation not only increases the burden on operators but also makes the testing process difficult to conduct flexibly.

[0004] 2. Difficulty in Precisely Controlling Pressure Intensity and Frequency: Traditional equipment typically relies on manual pressure application or simple mechanical structures, making it difficult to precisely control pressure intensity and frequency during testing. Because different signal switch models experience varying pressure conditions in practice, the reliability and reference value of test results will be compromised if precise pressure conditions are not provided during testing.

[0005] 3. Lack of automatic reset function and low efficiency: Existing test equipment requires manual reset after each press, which is not only time-consuming and labor-intensive, but also easily causes discontinuous test interruptions and makes it difficult to meet the requirements of long-term stable testing. Especially during durability testing, frequent manual resets not only waste human resources but also affect test consistency and reliability.

[0006] 4. Data monitoring is inconvenient and lacks real-time performance: Traditional test equipment is often lacking real-time data monitoring capabilities. Operators can only evaluate switch performance through post-analysis, rather than monitoring the test process in real time. This delayed data feedback is not conducive to timely identification and resolution of potential issues.

[0007] Therefore, it has become a technical requirement to develop a portable, stable test device suitable for testing various switch signals. Utility Model Content

[0008] In order to solve the above problems, the utility model provides a portable switch signal reliability test device. Through the improved structural design, the device has good portability, reset stability and applicability.

[0009] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0010] A portable switch signal reliability test device includes a frame, a power assembly, a cam assembly, a pressure plate, a self-resetting torsion shaft, a roller, a roller pin, a pressure-sensitive counter, a display, and a signal switch;

[0011] The power assembly is installed on the frame and is used to drive the cam assembly to rotate; the cam assembly is connected to the pressure plate, and acts on the pressure plate through the rotation of the cam to control the pressure of the pressure plate on the signal switch; the self-resetting torsion shaft is connected to the pressure plate, and is used to return the pressure plate to its initial position after the detection is completed; the roller and roller pin are used for smooth movement of the device; the pressure-sensitive counter is set on the frame and connected to the pressure plate, and is used to detect the pressure applied to the signal switch in real time; the display is connected to the pressure-sensitive counter, and is used to display the detected pressure data.

[0012] Preferably, the power assembly includes a speed reducer for reducing the rotation speed of the driving cam assembly, thereby ensuring that the pressure application process of the pressure plate on the signal switch is more stable.

[0013] Preferably, the self-resetting torsion shaft is a torsion spring structure, which is used to automatically reset the pressure plate after the test is completed.

[0014] Preferably, the roller and roller pin are arranged at the bottom of the frame, and the roller pin is used to fix the roller, thereby providing stable support during the movement.

[0015] Preferably, the pressure-sensitive counter is installed between the pressure plate and the signal switch, and is used to measure the real-time pressure value applied by the pressure plate on the signal switch, and send the measurement result to the display.

[0016] Preferably, the display is connected to the pressure-sensitive counter via a data line, and is used to display the pressure data measured by the pressure-sensitive counter in real time so that the operator can monitor the test situation.

[0017] Preferably, the signal switch is detachably mounted on the rack so that different types of signal switches can be replaced for testing according to different detection requirements.

[0018] Preferably, the frame is made of metal material to provide good structural strength and durability, so that the device remains stable during long-term use.

[0019] It can be seen from the above technical solutions that, compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. Portability and flexibility

[0021] This device features a compact design, small size, and lightweight.

[0022] 2. Stable test performance

[0023] The powertrain includes a speed reducer, ensuring the cam assembly's rotational speed is stable and controllable, ensuring consistent pressure applied by the pressure plate with each press. This consistent pressure application simulates the actual operating conditions of the switch, ensuring accurate testing and helping to verify the long-term durability and reliability of the signal switch.

[0024] 3. Efficient automatic reset function

[0025] The device's self-resetting torsion shaft, a torsion spring structure, is connected to a pressure plate. When the pressure plate applies pressure to the signal switch, the self-resetting torsion shaft automatically resets the pressure plate to its initial position. This automatic reset feature simplifies operation and enables continuous testing without manual resetting, significantly improving test efficiency and making it particularly suitable for high-frequency testing scenarios.

[0026] 4. Real-time monitoring and data feedback

[0027] A pressure-sensitive counter, installed between the pressure plate and the signal switch, measures the pressure applied by the pressure plate on the signal switch in real time and transmits the data to a display via a data cable. The display clearly displays the current pressure value, allowing operators to monitor the force applied to the signal switch during testing and identify any anomalies. This real-time monitoring function improves test controllability and safety, reducing errors caused by excessive or insufficient test pressure.

[0028] 5. Diverse applicability

[0029] The signal switch is detachably connected to the frame via a simple mounting structure, allowing for quick replacement.

The main components, including the powertrain, cam assembly, and pressure plate, are easily installed, resulting in a low failure rate. The interconnection between these components ensures efficient operation even during frequent testing, extending the device's service life.

[0032] 7. High test accuracy and stable results

[0033] The combination of the cam assembly and the powertrain ensures that the pressure plate consistently applies the same force to the signal switch. By carefully controlling the cam's shape and rotational speed, the applied pressure range can be adjusted each time, ensuring consistent test conditions. This precise control improves test accuracy, ensuring repeatable and reliable test results, and assists in comprehensively evaluating the quality and lifespan of signal switches.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] The following is a detailed embodiment of the portable switch signal reliability test device of the present invention to facilitate a better understanding of its structure and working principle.

[0040] Structural composition

[0041] like Figure 1 As shown, the device consists of the following main components:

[0042] Frame 1: The frame is the supporting structure of the entire device. Made of high-strength metal, it offers excellent rigidity and durability. Rollers 6 and roller pins 7 are designed at the bottom to facilitate movement. The upper portion of the frame houses mounting structures for other components, ensuring overall stability.

[0043] Powertrain 2: This powertrain, consisting of a motor and a reducer, is mounted on the frame and provides the driving force that drives the rotation of cam assembly 3. The reducer converts the motor's high-speed rotation into a low-speed, stable output, enabling controllable cam assembly speed and achieving periodic compression of the pressure plate.

[0044] Cam Assembly 3: This cam assembly is installed at the output end of the powertrain and features an eccentric cam design. As the cam rotates, its eccentric portion pushes platen 4 up and down. By adjusting the cam's shape and speed, the stroke and frequency of each press can be controlled to simulate different operating conditions.

[0045] Pressure plate 4: Attached to the eccentric portion of the cam, the pressure plate directly contacts the signal switch 10. As the cam rotates, the pressure plate periodically moves up and down, simulating the pressing action of the switch. The shape and material of the pressure plate are optimized to apply pressure evenly, ensuring consistent test conditions.

[0046] Self-resetting torsion shaft 5: The self-resetting torsion shaft is connected to the pressure plate and contains a torsion spring that automatically resets the pressure plate after it completes its pressing action. This design simplifies the device's operation and enables automatic reset for continuous testing.

[0047] Rollers 6 and roller pins 7: These rollers and roller pins are mounted on the bottom of the frame, allowing the device to be easily moved and positioned within the test area. They also provide support and cushioning, ensuring the device remains stable during movement.

[0048] Pressure-sensitive counter 8: Located between the pressure plate and the signal switch, the pressure-sensitive counter measures the pressure applied by the pressure plate to the signal switch. The counter transmits the measured data in real time to the display via a data line, helping the operator monitor the test process.

[0049] Display 9: Mounted on the frame, the display displays real-time pressure data from the pressure-sensitive counter, allowing operators to monitor and record test results. The display's interface is concise and clear, clearly displaying the current applied force and test status.

[0050] Signal switch 10: The signal switch is the test object of this device. It is fixed on the rack through a convenient mounting structure and can be quickly replaced to meet the test requirements of different types of switches.

[0051] How it works

[0052] In this embodiment, the working steps of the portable switch signal reliability test device are as follows:

[0053] 1. Preparation and Setup: Install the signal switch 10 on the rack 1 and adjust the device's fixing structure so that the position of the signal switch is aligned with the movement trajectory of the pressure plate 4. Connect the pressure-sensitive counter 8 and the display 9, ensuring that the data cable connection is stable.

[0054] 2. Start the powertrain: When powertrain 2 is started, the motor drives the reducer to produce a low-speed, stable rotational motion. The powertrain output drives the pressure plate 4 through the cam assembly 3, causing it to move up and down periodically, simulating the actual pressing of the switch.

[0055] 3. Platen Movement and Pressure: Driven by the powertrain, the eccentric portion of the cam assembly rotates, pushing platen 4 downward to press signal switch 10. By adjusting the cam's design parameters, the platen's pressing force and frequency can be controlled to suit different testing requirements.

[0056] 4. Real-time monitoring and data feedback: During each compression, the pressure-sensitive counter 8 measures the pressure applied by the pressure plate on the signal switch in real time and transmits the data to the display 9. The display shows real-time pressure data, allowing the operator to monitor the stability of the pressure at any time and ensure the reliability of the test conditions.

[0057] 5. Automatic reset: After each press, the self-resetting torsion shaft 5 automatically resets the pressure plate 4 to its initial position via the internal torsion spring. This design ensures that the device can operate continuously without manual intervention, improving test efficiency.

[0058] 6. Data recording and analysis: The operator can record and analyze the performance of the signal switch during long-term continuous pressing by observing the data on the display 9, thereby evaluating its reliability and durability.

[0059] Implementation Effect

[0060] In this embodiment, the portable switch signal reliability test device achieves the following effects through reasonable structural design:

[0061] 1. Portable and easy to operate: The frame design is light and sturdy, and the roller structure at the bottom ensures the convenient movement and rapid deployment of the device in different scenarios.

[0062] 2. Stable pressure effect: Through the precise control of the powertrain and cam assembly, the pressure plate can exert stable pressure on the signal switch, which can effectively simulate the switch operation during actual use.

[0063] 3. Automatic reset function improves test efficiency: The configuration of the self-resetting torque shaft enables the pressure plate to automatically reset after each press, reducing the need for operator intervention and is suitable for long-term reliability testing.

[0064] 4. Real-time monitoring of data facilitates quality control: The real-time monitoring function of the pressure-sensitive counter and display improves the controllability of the test and the reliability of the data, making the test results have a higher reference value.

[0065] 5. Wide applicability: The installation design of the signal switch allows for quick replacement of different types of switches, which is suitable for testing requirements of various types of signal switches, greatly improving the practicality of the device.

[0066] In summary, the portable switch signal reliability test device of the utility model is not only compact and easy to carry, but also has strong test reliability and stability. It is suitable for use in laboratories and production lines, and provides great convenience and support for the durability test of signal switches.
