Description

Technical Field

[0001] This utility model relates to the field of automotive electronic testing equipment technology, specifically an automotive electronic testing platform. Background Technology

[0002] In today's booming automotive industry, automotive electronic wiring harnesses, as a core component of the vehicle's electrical system, undertake the critical tasks of power transmission and signal transmission. With the continuous improvement of vehicle intelligence and electrification, the structure of electronic wiring harnesses is becoming increasingly complex, with a significant increase in the number of wires, connector types, and arrangement density. The quality of automotive electronic wiring harnesses directly affects the safety, reliability, and normal operation of various functions of the vehicle. Problems such as short circuits, open circuits, poor contact, and insulation damage in the wiring harness can lead to vehicle malfunctions and even safety accidents.

[0003] Currently available automotive electronic wiring harness testing equipment requires the wiring harness to be placed on a testing platform to test its conductivity. Then, the operator holds a multimeter probe in their left hand, touching the positive and negative probes to both ends of the wiring harness respectively, and observes the multimeter reading to determine whether there is continuity. During long-term work, operator finger fatigue can easily lead to poor contact of the probes, resulting in misjudgments.

[0004] Therefore, there is an urgent need for an automotive electronics testing platform to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0005] In view of this, the present invention proposes an automotive electronics testing platform, which aims to solve the problems existing in the prior art.

[0008] Take the electronic wire harness to be tested, center it in the placement rack, and then start the motor to move the two positioning seats with the two detection plates (the two detection plates represent the positive and negative plates respectively) so that the two detection plates contact the two ends of the wire harness respectively. At this time, the display will show the test value. After the wire harness test is completed, the detection plates will reset, and the wire harness can be taken out of the placement rack.

[0009] Furthermore, the present invention is improved in that the positioning seat and the detection module are connected via a control line, and the detection plate and the positioning seat are connected via a control line.

[0010] To improve the stability of the positioning seat during use, the present invention features an improvement where the cross-section of the slide groove is rectangular.

[0012] To facilitate the placement of wire harnesses inside the storage rack, the present invention includes the following improvement: two inclined plates are symmetrically arranged at the upper end of the storage rack, and the inclined plates and the storage rack are an integral structure.

[0013] To facilitate the replacement of the placement rack, the present invention includes an improvement whereby a base is provided at the lower end of the placement rack, and the base is fixed to the upper end of the testing table by screws.

[0027] With the rapid development of the automotive industry, electronic wiring harnesses, as a key component of automotive circuit systems, are primarily responsible for transmitting electrical energy and signals. As automotive intelligence and electrification levels increase, the structure of electronic wiring harnesses has become more complex, with a significant increase in the number of wires, connector types, and arrangement density. The quality of automotive electronic wiring harnesses directly affects the safety, stability, and normal operation of a vehicle. Problems such as short circuits, open circuits, poor contact, or insulation damage in the wiring harness can lead to vehicle malfunctions and even safety accidents.

[0028] Currently available automotive electronic wiring harness testing equipment requires the wiring harness to be placed on a testing platform to test its conductivity. Then, the operator holds a multimeter probe in their left hand, touching the positive and negative probes to both ends of the wiring harness respectively, and observes the multimeter reading to determine whether there is continuity. During long-term work, operator finger fatigue can easily lead to poor contact of the probes, resulting in misjudgments.

[0029] See Figures 1-5 This utility model discloses an automotive electronics testing platform, including a testing platform 1. The upper end of the testing platform 1 is provided with a placement frame 2. Two sliding grooves 6 and a positioning seat 7 are symmetrically arranged on the testing platform 1 with respect to the placement frame 2. The lower end of the positioning seat 7 is provided with a slider 8 that is slidably connected to the sliding groove 6. The lower end of the testing platform 1 is provided with a fixing frame 10. The fixing frame 10 is provided with a motor 11. The output end of the motor 11 is provided with a rotating shaft 12. Two threaded rods 13 with reverse thread structure are symmetrically arranged on the rotating shaft 12. The two threaded rods 13 pass through the two sliders 8 respectively and are threadedly connected to the sliders 8.

[0030] The upper end of the testing station 1 is provided with a testing module 14, and the upper end of the testing module 14 is provided with a display 15. The testing module 14 is connected to the positioning seat 7 by an electrical signal. The upper end of the positioning seat 7 is provided with a testing plate 9, and the testing plate 9 is connected to the positioning seat 7 by an electrical signal.

[0031] The detection plate 9 and the positioning seat 7 are connected via control lines.

[0032] The cross-section of the slide 6 is rectangular.

[0033] This automotive electronics testing platform achieves automated testing of automotive electronic wiring harnesses through the coordinated operation of mechanical structures and electrical systems. First, the operator places the electronic wiring harness to be tested into the placement rack 2 at the top of the testing table 1.

[0034] The placement rack 2 has a U-shaped cross-section, and a clamping pad 3 is provided on the inner wall of the placement rack 2. The clamping pad 3 is adhered to the inner wall of the placement rack 2, and the clamping pad 3 is made of rubber.

[0035] The placement rack 2 is U-shaped, and the rubber clamping pad 3 adhered to the inner wall can fit tightly against the wire harness to prevent the wire harness from shifting during the testing process;

[0036] Two inclined plates 4 are symmetrically arranged at the upper end of the placement rack 2. The inclined plates 4 and the placement rack 2 are an integral structure. The symmetrically arranged inclined plates 4 at the upper end form a guide structure, which facilitates the wire harness to slide into the placement rack 2 quickly and accurately.

[0037] Subsequently, the motor 11 on the mounting bracket 10 is started, and the shaft 12 at the output end of the motor 11 drives the two reverse-threaded rods 13 on it to rotate. Since the threaded rods 13 are threadedly connected to the slider 8 at the lower end of the positioning seat 7, and the slider 8 can slide within the rectangular groove 6 of the detection table 1, the two positioning seats 7 will move relative to each other or in opposite directions along the groove 6 under the drive of the threaded rods 13. When the positioning seats 7 move, the detection plates 9 on them (representing the positive detection end and the negative detection end respectively) will move synchronously and contact both ends of the wire harness, thereby forming a current path.

[0038] At this point, the detection board 9 transmits the detected electrical signal to the positioning seat 7 via a control line, and the positioning seat 7 then transmits the signal to the detection module 14. After analyzing and processing the signal, the detection module 14 transmits the detection result to the display 15 on its upper end for visual display. The operator can determine whether the wire harness has short circuits, open circuits, or other conductivity problems based on the values ​​displayed on the display 15. After the test is completed, the motor 11 is restarted to reset the positioning seat 7, separating the detection board 9 from the wire harness. The operator can then remove the tested wire harness, completing one testing cycle.

[0039] The lower end of the placement rack 2 is provided with a base 5, which is fixed to the upper end of the testing table 1 by screws.

[0040] The placement rack 2 is fixed to the testing table 1 with screws via the base 5, making it easy to replace and adapt to the testing needs of wire harnesses of different specifications.

[0041] The integrated design of the detection module 14 and the display 15 enables the detection results to be presented in real time and intuitively, facilitating operators to quickly obtain detection information, promptly handle non-conforming products, and improve production management efficiency.

[0042] The detection module 14 is a crucial component of the automotive electronics testing platform for determining the conductivity of the wiring harness. During operation, the electrical signals collected by the detection board 9 are transmitted to the detection module 14 via the positioning seat 7. Its internal multi-channel analog signal acquisition circuit quickly converts the analog signals into digital signals for subsequent processing. The high-precision resistance measurement module, based on Ohm's law, sends a specific current signal to the wire, measures the voltage drop to calculate the resistance value, and uses multiple measurements to average the results to ensure accuracy. Next, the microprocessor analyzes the resistance data according to preset standard values ​​and algorithms to determine the condition of the wiring harness. If the resistance value is far outside the normal range, it may indicate an open circuit; if it fluctuates significantly within a certain range, it may indicate poor contact. Finally, the detection module 14 outputs the judgment results as electrical signals to the display 15, presenting them visually through numbers, graphics, or colors. Normal wires are displayed in green ("normal"), and faulty wires are displayed in red ("faulty").

[0043] Understandably, this invention enables automated testing and improves efficiency: the testing platform automatically contacts both ends of the wiring harness via a motor-driven positioning seat and testing board, significantly shortening testing time, improving efficiency, and reducing labor costs. Simultaneously, this invention achieves accurate testing and reduces misjudgments: it avoids the misjudgment problems caused by poor contact of the probes due to finger fatigue during manual testing. Stable contact between the testing board and the wiring harness, combined with precise signal processing by the testing module, ensures the accuracy and reliability of the testing results, effectively guaranteeing the quality of automotive electronic wiring harnesses.
