Description

Technical Field

[0001] This utility model belongs to the field of automotive electronic equipment testing technology, specifically relating to an ECU assembly testing device. Background Technology

[0002] As a core component of automotive electronic systems, the ECU (Electronic Control Unit) undergoes performance testing after assembly, which is crucial for ensuring safe vehicle operation. Current ECU testing methods commonly suffer from the following problems:

[0003] ECU installation and heat dissipation issues: Traditional testing devices have a simple ECU placement structure, often placing the ECU directly on a flat plate. This results in the bottom of the ECU being in close contact with the placement surface, leading to poor heat dissipation. During prolonged testing, the temperature may become too high, affecting test accuracy or even damaging the ECU. At the same time, the ECU lacks a stable positioning structure, making it prone to displacement during testing due to vibration or cable pulling, affecting the stability of the test connection.

[0004] The testing equipment lacks flexibility: During the testing process, the position of the testing equipment (such as test probes, signal connectors, etc.) needs to be adjusted according to the test interface position of different ECU models. However, the existing testing equipment is mostly fixed and cannot be moved easily. When adapting to different ECU testing needs, the operation is cumbersome and inefficient.

[0005] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

[0006] The main purpose of this invention is to provide an ECU assembly and testing device that combines stable ECU installation, efficient heat dissipation, flexible adjustment of testing equipment, and structural stability, thereby improving the efficiency and accuracy of ECU testing.

[0024] This utility model discloses an ECU assembly and testing device. The specific embodiments of the utility model will be further described below with reference to preferred embodiments.

[0025] In the embodiments of this utility model, those skilled in the art will note that the ECU and the like involved in this utility model can be considered as prior art.

[0026] Preferred embodiment.

[0027] like Figure 1-3 As shown, this utility model discloses an ECU assembly and testing device, including a bracket module 10, a placement module 20, and a testing equipment mounting module 30. Both the placement module 20 and the testing equipment mounting module 30 are mounted on the bracket module 10, wherein:

[0028] The support module 10 includes a base plate 11, a top plate 12, a first support rod 13 and a second support rod 14, wherein the first support rod 13 and the second support rod 14 are fixedly installed between the base plate 11 and the top plate 12.

[0029] The placement module 20 includes a placement plate 21, which is provided with a plurality of pads 22 and mounting rods 23. The pads 22 are used to place the ECU 40 (so that there is a distance between the bottom of the ECU and the placement plate to facilitate heat dissipation), and the mounting rods 23 are used to insert into the housing mounting holes of the ECU 40 (so that the ECU is securely mounted on the placement plate).

[0030] The test equipment mounting module 30 includes a first slide rail assembly 31, a second slide rail assembly 32, a mounting bracket 33, and a handle 34. The first slide rail assembly 31 and the second slide rail assembly 32 are respectively mounted on the top plate 12. The two ends of the mounting bracket 33 are respectively connected to the first slide rail assembly 31 and the second slide rail assembly 32. The mounting bracket 33 is provided with a plurality of fixing holes 331 (through which the test equipment is mounted for testing the ECU). The handle 34 is mounted on the mounting bracket 33 (to facilitate the movement of the mounting bracket on the first / second slide rail assembly, thereby moving the test equipment as needed).

[0031] Specifically, a baffle 121 is provided on one side of the top plate 12 (to prevent the mounting bracket from moving excessively on the first / second slide rail assembly).

[0032] More specifically, a first reinforcing plate 15 is provided between the first support rod 13 and the top plate 12, and a second reinforcing plate 16 is provided between the first support rod 13 and the bottom plate 11. A third reinforcing plate 17 is provided between the second support rod 14 and the top plate 12, and a fourth reinforcing plate 18 is provided between the second support rod 14 and the bottom plate 11 (to improve structural strength).

[0033] Furthermore, the baffle 121 is provided with a first insertion hole and a second insertion hole, and the mounting bracket 33 is provided with a first insertion rod 332 and a second insertion rod 333. The first insertion rod 332 is aligned with the first insertion hole and the second insertion rod 333 is aligned with the second insertion hole. (When the ECU needs to be tested, the mounting bracket with the test equipment is moved above the ECU by the handle. At this time, the first insertion rod is inserted into the first insertion hole and the second insertion rod is inserted into the second insertion hole to limit the mounting bracket and improve the stability during testing.)

[0034] Furthermore, the top plate 12 is also provided with a cable rack 122 (to facilitate the orderly placement of cables and to facilitate equipment connection and testing).

[0035] The testing procedure for this utility model is as follows:

[0036] 1. ECU Placement and Fixing: The operator aligns the mounting holes of the ECU to be tested with the mounting rods on the mounting plate and slowly inserts the mounting rods to place the ECU stably on the pad. At this time, a gap is formed between the bottom of the ECU and the mounting plate, which can achieve heat dissipation through air convection.

[0037] 2. Installation and Position Adjustment of Test Equipment: According to the testing requirements of the ECU to be tested, fix the corresponding test equipment (such as ECU signal detector, DC power supply) to the fixing holes of the mounting bracket with bolts;

[0038] 3. The operator holds the handle and pushes the mounting bracket along the first and second slide rail assemblies to move the test equipment directly above the ECU. When the mounting bracket moves to the test position, the first and second insert rods on the mounting bracket are aligned with the first and second insertion holes on the baffle, respectively. The insert rods are inserted into the insertion holes to complete the limiting and fixing of the mounting bracket.

[0039] 4. Cable Connection and Testing: Organize the power cables and signal cables of the test equipment and place them in the cable rack on the top plate to avoid cable tangling; the operator connects one end of the cable to the test equipment and the other end to the ECU's test interface to complete the test preparation; start the test equipment and test the ECU's performance parameters (such as signal output, voltage stability, etc.). During the test, the overall structure of the device is stable, the ECU has good heat dissipation, and the cable connections are orderly.

[0040] 5. Test Completion and Equipment Reset: After the test, disconnect the cable connection and store the cable in the cable rack; pull out the plug and use the handle to move the mounting bracket back to its initial position along the slide rail; remove the tested ECU to proceed with the test of the next ECU.

[0041] It is worth mentioning that the ECU and other technical features involved in this utility model patent application should be regarded as prior art.
