[0002] With the development of automotive technology, automotive electrical systems have become increasingly complex. Numerous electronic control units (ECUs), such as electronic fuel injection systems, anti-lock braking systems (ABS), and electronic stability programs (ESP), are now used in automobiles. The emergence of these systems has placed higher demands on testing equipment. Traditional multimeters are no longer sufficient for testing needs; oscilloscopes have also become widely used in automotive electrical testing to assess the signal transmission quality. Oscilloscopes can display the waveforms of voltage and current changes over time in a circuit, helping testers identify problems such as signal interference and pulse anomalies. For example, when testing sensor signals in a car, an oscilloscope can clearly display whether the analog signal waveform output by the sensor is normal, thereby determining the sensor's operating status.

[0003] With the rapid development of the automotive industry, automotive electrical systems are becoming increasingly complex. Accurate and efficient testing of automotive electrical systems has become a key aspect of ensuring vehicle performance and safety. Currently, some oscilloscopes have certain shortcomings, lacking effective fixing devices for the cables connecting the test probes. These cables are easily loosened by pulling during use, thus affecting the accuracy of the test results. Therefore, an automotive electrical testing device is proposed to solve the above problems.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 2This utility model provides an embodiment of an automotive electrical testing device, comprising an oscilloscope 1. The oscilloscope 1 is made of high-quality electronic components, possessing high stability and accuracy, and can accurately detect various parameters of automotive electrical systems. A display screen 11 is fixedly connected to the front end of the oscilloscope 1. The display screen 11 uses a high-resolution LCD screen, which can clearly display the test results for easy viewing by staff. An interface slot 12 is provided at the front end of the oscilloscope 1. The interface slot 12 is reasonably designed, allowing for convenient connection of various test probes and improving testing efficiency. A cable 2 is slidably connected inside the oscilloscope 1. The cable 2 is made of high-quality insulating material, possessing good wear resistance and corrosion resistance, ensuring long-term use. Two compression blocks 3 are rotatably connected to the front end of the oscilloscope 1. The compression blocks 3 are made of high-strength plastic material, possessing good toughness and wear resistance, and can effectively fix the cable 2.

[0032] The two compression blocks 3 have grooves at their front ends, designed to better adapt to the shape of the cable 2 and improve the stability of the fixation. Rotating rod 1 4 is slidably connected to the outside of the two compression blocks 3. Rotating rod 1 4 is made of stainless steel, possessing good strength and corrosion resistance, and can withstand significant tensile force. Rotating rod 2 5 is slidably connected to the outside of the two compression blocks 3. Rotating rod 2 5 is made of aluminum alloy, possessing light weight and good strength, and is easy to operate. Rotating rod 3 7 is rotatably connected to the rear end of rotating rod 1 4. Rotating rod 3 7 is made of high-strength steel, possessing good toughness and strength, and can effectively transmit tensile force. Handle 8 is rotatably connected to the top of rotating rod 3 7. Handle 8 is made of rubber, possessing good anti-slip properties and comfort, and is convenient for operators. Pulling rod 1 6 is rotatably connected to both sides of rotating rod 2 5. Pulling rod 1 6 is made of aluminum alloy, possessing light weight and good strength, and can effectively transmit tensile force. The adjacent sides of the two pulling rods 1 6 are rotatably connected to the two sides of rotating rod 3 7.

[0033] A locking block 9 is fixedly connected to the front end of the handle 8. The locking block 9 is made of high-strength plastic material, which has good toughness and wear resistance, and can effectively fix the position of the handle 8. The bottom end of the rotating rod 1 4 is rotatably connected to the top end of the rotating rod 2 5. The top end of the rotating rod 1 4 has a slot 10. The design of the slot 10 can better fix the position of the locking block 9 and improve the stability of the fixation. The outside of the locking block 9 is slidably connected to the inside of the slot 10. The two pressing blocks 3 are coupled to the outside of the cable 2 on their adjacent sides. Through this design, the cable 2 can be effectively fixed, preventing the cable 2 from loosening during use, thereby affecting the test results. A protective shell 13 is fixedly connected to the rear end of the oscilloscope 1. The protective shell 13 is made of high-strength plastic material, which has good protection and can effectively protect the internal components of the oscilloscope 1. The rear end of the oscilloscope 1 is provided with a mounting component for quick installation.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The mounting assembly includes a protective housing 13, which serves as the outer shell of the entire assembly and is made of high-strength engineering plastic. Engineering plastic possesses excellent toughness and impact resistance, effectively protecting internal components from external collisions or accidental impacts, ensuring the structural integrity of the entire mounting assembly. Its front end is fixedly connected to the rear end of the oscilloscope 1. This tight connection provides stable support for the oscilloscope 1, preventing it from detaching from the mounting assembly during use and ensuring smooth measurement operations. A rotating disk 14 is rotatably connected inside the protective housing 13. The rotating disk 14 is made of high-quality metal alloy, which possesses good wear resistance and high strength, capable of withstanding various forces generated during oscilloscope 1 position adjustments, ensuring smooth and stable rotation.

[0035] The rotation of the rotating disk 14 plays a crucial role in the adjustment mechanism of the entire mounting assembly. It accurately transmits externally applied tension or thrust to other related components, enabling fine adjustment of the oscilloscope 1's position. Two drive rods 15 are rotatably connected to the rear end of the rotating disk 14. These drive rods 15 are made of solid carbon steel, possessing high rigidity and strength. When the rotating disk 14 rotates, they effectively transmit power, ensuring stable force transmission and allowing subsequent components to move in a predetermined manner, thereby achieving accurate adjustment of the oscilloscope 1's position. Driven rods 16 are rotatably connected to the opposite sides of each of the two drive rods 15. These driven rods 16 are made of lightweight aluminum alloy, a material that ensures both strength and light weight. This allows the driven rods 16 to slide flexibly under the pull of the drive rods 15, preventing excessive weight from affecting the sensitivity of the entire adjustment process.

[0036] Each of the two driven rods 16 has a slider 17 rotatably connected to its opposite side. The slider 17 is made of wear-resistant nylon, which has a low coefficient of friction and good wear resistance. This allows the slider 17 to slide smoothly within the cavity, reducing energy loss and component wear caused by friction, while also ensuring that it can still accurately perform its position adjustment function during long-term use. A fixing plate 18 is fixedly connected to the rear end of each of the two sliders 17, and the oscilloscope 1 is fixed by the opposing clamping of the fixing plates 18. A second traction rod 19 is rotatably connected to the top of the rotating disk 14. The second traction rod 19 is made of high-strength stainless steel. The high strength and corrosion resistance of stainless steel ensure that it maintains good performance during frequent pulling operations and will not deform or be damaged due to prolonged stress.

[0037] The second traction rod 19 plays a crucial traction role throughout the adjustment process. It accurately transmits the force applied externally to the slider 20 to the rotating disk 14, thereby activating the entire adjustment mechanism. The protective shell 13 has openings on its exterior. The size and shape of these openings are carefully designed to perfectly fit the slider 17, ensuring that the slider 17 slides within them without jamming and guaranteeing the accuracy of its trajectory, thus achieving precise adjustment of the oscilloscope 1's position. The two sliders 17 are externally slidably connected to the interior of these openings. The sliding of the sliders 17 within these openings drives the connected driven rod 16 to move accordingly, thereby achieving overall adjustment of the oscilloscope 1's position.

[0038] The external sliding connection of the second traction rod 19 includes a fixing block 21. The fixing block 21 is made of hard rubber, which has elasticity and good friction. When the fixing block 21 slides downwards, it can firmly lock into the slot using its own friction, effectively fixing the position of the sliding block 20. This fixing method is not only simple and easy to implement, but also ensures the fixing effect while avoiding excessive compression or damage to other components. The top of the second traction rod 19 is fixedly connected to a sliding block 20, which is made of smooth plastic. Its smooth surface makes pulling the sliding block 20 smoother, reducing resistance during hand operation and facilitating quick and accurate adjustment by the operator. The protective shell 13 and the top of the oscilloscope 1 have a slot. The slot is designed with high precision to accurately match the fixing block 21, ensuring that the fixing block 21 accurately embeds into the slot during downward sliding, thereby reliably fixing the position of the sliding block 20 and preventing the oscilloscope 1 from becoming loose.

[0039] Working Principle: When staff need to test the electrical components of a car, the device may shake or fall during measurement, affecting the measurement results. To address this, the oscilloscope 1 is repositioned. Then, by pulling the slider 20, the traction rod 19 is pulled, causing the rotating disk 14 to rotate. This rotation of the disk 14 causes the transmission rods 15 on both sides to rotate, pulling the driven rods 16 on both sides. This causes the slider 17 to move the fixing plate 18 towards each other, thus fixing the oscilloscope 1 in place. After fixing, the fixing block 21 is slid down to secure the slider 20, preventing the oscilloscope 1 from shifting. This quick fixation of the oscilloscope 1 ensures it will not shake or fall during use, thus preventing any impact on measurement results.

[0040] When connecting the oscilloscope 1 to the test probe, the rotating rod 4 can be grasped and slid outside the extrusion block 3. After sliding into the groove at the top of the extrusion block 3, the handle 8 can be manually grasped and rotated to the top. When the handle 8 is rotated, the rotating rod 7 will pull the rotating rod 4 inward, and the traction rod 6 will also drive the rotating rod 5 inward until the rotating rod 5 and the rotating rod 4 stably fix the cable 2. At this time, the locking block 9 is slid into the slot 10 to fix the fixed position and prevent the cable 2 from loosening. By using a fixing bracket, unnecessary pulling during use is avoided, which would affect the connection between the cable 2 and the oscilloscope 1 and thus affect the test results.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
