[0002] In related fields, automobiles, rail transit, and airplanes are all equipped with data recorders, also known as black boxes, to record driving data. The data stored in the black box is quite important; in the event of an accident, this data serves as the basis for determining the cause of the accident. In the rail transit sector, with the large-scale construction of high-speed rail, subways, and other rail transit systems, the demand for data recorder devices is constantly increasing, requiring manufacturers of data recording and storage devices to improve production efficiency to meet the needs of rapid production.

[0003] Existing recording and storage devices are generally tested individually, which results in low production efficiency. Testing individual recording and storage devices and fixing them to the test board lacks limiting, making insertion and removal inconvenient. The test fixtures are easily damaged after repeated insertion and removal, and replacing the entire test fixture is costly.

[0004] Therefore, a solution is needed. Utility Model Content

[0035]

[0036] Data Description

[0037] Test quantity and time consumption: Existing technology can only test one protection recorder at a time, while this utility model can test five at the same time. Under the condition that the time consumption of a single test is the same, the total time consumption of a single test does not increase, thus greatly improving the testing efficiency.

[0038] Insertion and removal alignment time: Existing technology lacks a limiting structure, and alignment during insertion and removal takes a long time; This utility model makes insertion and removal alignment more convenient and shortens the time by cooperating with the guide rail device and the guide rail embedded in the slide groove.

[0039] Maintenance costs: Existing testing fixtures have high overall replacement costs. This utility model adopts a modular design, and only the corresponding parts need to be replaced when there is partial damage, thus reducing maintenance costs.

[0040] Equipment temperature: Existing technology has poor heat dissipation effect, and the equipment temperature is high after continuous operation; This utility model enhances heat dissipation through heat dissipation mesh and heat dissipation holes, thereby reducing the equipment temperature and making it more conducive to stable operation.

[0041] Data Validity Statement

[0042] The data is based on the same test environment, the same specifications of protective recorders, and the same standard test procedures, and is therefore comparable.

[0043] The number of tests, time consumption, and insertion / removal alignment time were averaged through multiple repeated tests to reduce random errors.

[0044] The equipment temperature is measured using professional temperature measuring instruments under the same working conditions.

[0045] The present invention comprises: 1. Device body; 2. Protective recorder; 3. Test chassis; 4. Test back plate; 5. Connecting cable; 6. Test device; 7. Base frame; 8. Front mounting plate; 9. Side mounting plate; 10. Guide rail device; 11. Heat dissipation mesh plate; 12. Heat dissipation hole; 13. Test operation handle; 14. Horizontal guide rail; 15. Vertical guide rail; 16. Guide rail locking block; 17. Guide rail embedded groove; 18. Top cover; 19. Lifting handle; 20. Recording terminal; 21. Main test board; 22. Locking plate; 23. Fixing hole; 24. Test terminal. All components are general standard parts or those skilled in the art. The components, whose structure and principles are known to those skilled in the art, can be understood by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing recording and storage devices generally adopt a single testing method, which results in low production efficiency. Testing a single recording and storage device and its connection and fixation to the test board lacks limiting, making insertion and removal inconvenient. The test fixture is easily damaged after repeated insertion and removal, and the overall replacement of the test fixture is costly. This utility model, through the combination of the above-mentioned components, can realize the testing of multiple protection recorders at one time, which greatly improves the testing efficiency. The addition of guide rails to the fixture facilitates test assembly and improves the standardization of testing.
