Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to a new energy vehicle safety performance testing device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the national testing standards for the safety performance of new energy vehicles are becoming increasingly stringent, clearly requiring comprehensive testing of core indicators such as vehicle insulation resistance, potential equalization, and charging function.

[0003] Currently, the industry mostly adopts a multi-station, sub-item testing model for the aforementioned testing items. This means that different testing items need to be completed at independent workstations using different equipment. This model has the following problems: First, the testing process is fragmented, requiring frequent transfers of vehicles or workpieces, resulting in low testing efficiency. Second, the equipment layout is scattered, occupying a large space and requiring separate operation and data recording systems, increasing equipment investment costs. Third, the testing data from different devices cannot be linked in real time, which can easily lead to data gaps or errors, affecting the accuracy and consistency of the testing results.

[0004] Therefore, this utility model proposes a safety performance testing device for new energy vehicles. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a safety performance testing device for new energy vehicles, so as to solve the problems of scattered testing processes, high equipment investment costs and poor data linkage mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution: a new energy vehicle safety performance testing device, including an electric platform cabinet, wherein a display screen is electrically connected to a built-in control board at the front of the electric platform cabinet near the top, so as to intuitively display the results data of different tests; The front of the power platform cabinet is fixedly connected to a function key area near the top of the display screen, so that the entire safety performance detection program can be operated using multiple buttons in the function key area. A resistance tester is installed at the bottom inside the electrical platform cabinet to test the resistance value of the internal circuit. One side wall of the electrical platform cabinet is provided with a plug-in placement area to enable the plug-in use of different testing tools; The fast charging tester and slow charging tester are placed on the rear wall of the power platform cabinet near the middle to test the fast charging and slow charging performance.

[0007] The present invention is further configured such that: the function key area includes a power switch, an industrial control computer switch, a start test button, a stop test button, a USB interface and an emergency stop switch arranged in sequence, and all of them are electrically connected to the control board built into the power platform cabinet.

[0008] Through the above technical solution, the components of the function key area and the built-in control board form a linkage control loop: the power switch is used to control the on / off of the main power supply of the entire device, providing basic power control for the device's power supply system; the industrial computer switch is used to start or stop the built-in industrial computer, which, as the core control unit of the device, is responsible for parsing operation instructions, processing test data, and coordinating the work of each test module; the start test button and the stop test button send "start test" and "stop test" commands to the industrial computer respectively, triggering or interrupting the test process; the USB interface enables data interaction between external storage devices and the industrial computer, used to export test reports or import device calibration parameters; the emergency stop switch is a safety protection component. When the device malfunctions, pressing the emergency stop switch can directly cut off the control loop, forcibly stopping the operation of all test modules and preventing equipment damage or safety accidents.

[0009] The present invention is further configured such that a storage drawer for a keyboard and mouse is slidably connected to the front part of the power platform cabinet near the middle position.

[0010] Through the above technical solution, the storage drawer adopts a sliding structure design and is connected to the front cabinet of the power platform cabinet through a slide rail, which can realize smooth push and pull operation; the internal space of the drawer is adapted to standard keyboard and mouse, which can not only store and protect the keyboard and mouse when not in use to avoid dust accumulation or damage from external impact, but also can be quickly pulled out during testing operations, so that operators can easily input parameters to the industrial control computer or retrieve historical test data via keyboard and mouse, thus improving the convenience of operation.

[0011] The present invention is further configured such that: a printer bracket and a coding gun bracket are bolted to the middle of the other side wall of the power platform cabinet, and the coding gun bracket is located at the bottom of the printer bracket.

[0012] With the above technical solution, both the printer bracket and the coding gun bracket are fixed to the side wall of the electrical platform cabinet with bolts, resulting in a stable connection structure that is easy to disassemble and maintain. The printer bracket is used to hold the test report printer. After the printer is electrically connected to the built-in control board, it can print the test results in real time and form a paper report for archiving. The coding gun bracket is used to fix the coding gun, which can mark and code qualified vehicles or parts, realizing a closed loop of the "test-record-mark" process. The vertical arrangement of the two brackets can make full use of the space on the side wall of the cabinet, avoid cluttered placement of equipment parts, and optimize the overall layout of the equipment.

[0014] Through the above technical solution, the plug-in placement area serves as the centralized area for the connection interfaces between the equipment and the vehicle under test. Each interface has a clear division of labor and an orderly layout: the fast charging port and slow charging port are conventional charging interfaces, compatible with standard vehicle charging plugs, used for performance testing under simulated daily charging scenarios; the fast charging heavy-duty connector and slow charging heavy-duty connector are high-power connection interfaces, with a heavy-duty design to withstand large current transmission, suitable for potential equalization and insulation resistance testing under high-voltage fast charging and slow charging conditions; the high-voltage output heavy-duty connector is used to connect to the vehicle's high-voltage system, providing a connection channel for high-voltage circuit resistance testing; the self-locking switch is an interface safety protection component. When the interface is not fully plugged in or becomes loose, the self-locking switch can trigger a signal to the built-in control board, prohibiting the start of the testing process and avoiding data errors or electric shock risks due to poor connection.

[0015] The present invention is further configured such that: both the fast charging port and the fast charging heavy-duty connector are electrically connected to the fast charging tester, and the fast charging tester is connected to the display screen through an electrically connected built-in control board.

[0016] Through the above technical solution, the fast charging port, the fast charging heavy-duty connector, and the fast charging tester form a fast charging detection loop: After the vehicle under test is connected to the device through the fast charging port or the fast charging heavy-duty connector, the fast charging tester can collect parameters such as voltage, current, and power during the charging process and analyze the parameters in real time; at the same time, the fast charging tester transmits the collected raw data and analysis results to the built-in control board. After the control board processes the data, it displays it intuitively on the display screen in the form of numbers, curves, etc., which is convenient for operators to monitor the fast charging detection process and results in real time.

[0017] The present invention is further configured such that: both the slow charging port and the slow charging heavy-duty connector are electrically connected to the slow charging tester, and the slow charging tester is connected to the display screen through an electrically connected built-in control board.

[0018] Through the above technical solution, the slow charging port, the slow charging heavy-duty connector, and the slow charging tester form a slow charging detection loop. Its working principle is the same as that of the fast charging detection loop, but it is adapted to slow charging operating parameters: the slow charging tester collects key parameters of the vehicle during the slow charging process through the slow charging interface and tests the stability and safety of the slow charging function; after the test data is processed by the slow charging tester, it is transmitted to the built-in control board. The control board converts the data into visual information and displays it on the screen. At the same time, it can be compared and stored with the fast charging test data to realize integrated management of charging and discharging function test data.

[0024] like Figure 1 As shown, a keyboard and mouse storage drawer 9 is slidably connected to the front of the power platform cabinet 1 near the middle.
