As a key component of an EV, it is equivalent to the powertrain of a traditional gasoline-powered vehicle. Its main components include an electric motor, battery pack, inverter, and transmission mechanism. The electric motor is the core, converting electrical energy into mechanical energy; the battery pack stores electrical energy; the inverter converts direct current (DC) to alternating current (AC); and the transmission mechanism transmits power to the wheels. The battery pack provides electrical energy to the inverter, which converts the energy and supplies it to the electric motor, which generates kinetic energy to drive the wheels through the transmission mechanism. Therefore, the electric drive system is the core of an EV's powertrain, and its performance directly affects the driving experience and energy efficiency. During EV production, the electric drive system needs performance testing. In current technology, this is typically done by operators connecting multiple connectors to perform the tests.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0027] It should be noted that, in a specific embodiment of the present invention, the test component is an electric drive assembly, and the application field is the electric vehicle manufacturing field. Example 1
[0028] Reference Figure 1 As shown, this utility model discloses a test tray integration device, through which the test piece can be connected to a test bench for performance testing.
[0029] The test tray integration device includes a main unit, which includes a base 1, a mounting plate 2, a terminal block 3, and a docking assembly. The mounting plate 2 is disposed on the base 1 along the height direction and is disposed on one side edge of the base 1.
[0030] The mounting plate 2 is provided with mounting holes, and the docking component is mounted on the mounting plate 2 through the mounting holes.
[0031] Meanwhile, the docking component is connected to the terminal 3 to enable mutual signal transmission.

The docking component includes a first plug-in component 41, a second plug-in component 42, and a coolant port 43. The first plug-in component 41 is used for a first signal exchange, the second plug-in component 42 is used for a second signal exchange, and the coolant port 43 is used for coolant inlet and outlet.
[0033] The test tray integration device further includes a docking tray unit, which includes at least one docking tray and a wiring harness assembly disposed on the docking tray. One end of the wiring harness assembly is connected to the terminal block, and the other end of the wiring harness assembly is connected to the docking tray. In this way, the docking tray is electrically connected to the main unit through the wiring harness assembly.
[0034] Specifically, at least one of the docking trays is detachably mounted on the base 1, and the test piece can be connected to and positioned on the docking tray, so that the test piece and the test bench can be electrically connected through the docking assembly to exchange signals.
[0035] It should be noted that different docking trays can be adapted to different products. Therefore, when performing performance tests on different test pieces, it is only necessary to replace the different docking trays and make the corresponding connections.
[0036] Therefore, it can be understood that the test tray integration device protected by this utility model includes a main unit and a docking tray unit. The main unit includes a base, a mounting plate, a terminal block, and a docking assembly disposed on the base. The docking assembly is used to dock with the test bench. The terminal block has an electrical connection with the docking assembly. The docking tray unit includes at least one docking tray, which is used to carry the test piece. After the test piece is assembled on the docking tray, the docking tray is electrically connected to the terminal block, thereby connecting the test piece mounted on the docking tray to the test bench through the docking assembly of the main unit for further performance testing. The test tray integration device of this utility model allows the main unit to be connected to various different docking trays. Therefore, when changing different models of test pieces, only the matching docking tray needs to be replaced. The test piece is positioned on the docking tray, and there is an electrical connection between the test piece and the docking tray. Then, the docking tray is assembled on the base of the main unit, so that the docking tray is simultaneously electrically connected to the docking assembly. Since the docking assembly can be electrically connected to the test bench, signal transmission between the test piece and the test bench is achieved. This device can quickly switch between different products for testing, and can quickly clamp and install, effectively improving the testing efficiency of the test pieces. It has high adaptability and is suitable for testing a variety of products. It is easy for operators to change and operate, and has high compatibility.

The first plug-in assembly 41 also includes two first plug-in positioning rods 410, which are arranged opposite to each other on both sides of the first plug-in connector along the height direction, thereby playing a floating guiding role to facilitate the operator to connect the first plug-in assembly 41 to the test bench.
[0040] In detail, the first insertion positioning rod 410 is cylindrical, and its outwardly extending end is also provided with a chamfer structure, which makes it easier for operators to insert.

[0044] Furthermore, the docking tray unit includes a first docking tray, which comprises a first base plate 51, a first mounting frame 52, and a first adapter assembly. The first mounting frame 52 is disposed on the first base plate, and the first adapter assembly is mounted on the first base plate 51. Thus, a test piece suitable for the first docking tray is electrically connected to the main unit via the first adapter assembly. Simultaneously, the test piece can be detachably assembled to the first mounting frame 52 using fasteners.
[0045] In detail, the first adapter assembly is electrically connected to the terminal 3 via a wiring harness assembly. Specifically, the first adapter assembly includes four first adapters 53, which are respectively arranged at both ends of the first base plate 51 along the diagonal direction.
[0046] Furthermore, the docking tray unit includes a second docking tray, which comprises a second base plate 61, a second mounting frame 62, and a second adapter assembly. The second mounting frame 62 is disposed on the second base plate 61, and the second adapter assembly is mounted on the second base plate 61.

With this configuration, the test piece adapted to the second docking tray can achieve electrical connection with the main unit via the second adapter assembly. Simultaneously, the test piece can be detachably mounted to the second mounting frame 62 using fasteners.
[0047] In a preferred embodiment, the main body unit further includes two limiting baffles 10 and a top plate 12. The two limiting baffles 10 are disposed on opposite side edges of the base 1.

The two limiting baffles 10 and the mounting plate 2 can enclose and form a receiving space. In this way, the docking tray unit can be received in the receiving space to ensure stability during testing and to provide a certain degree of retraction for the wire harness assembly.
[0048] To ensure the stability of the docking between the test bench and the main unit during testing, and to ensure the stability of signal connection and transmission, the main unit further includes a positioning component disposed on the first mounting surface. The positioning component includes at least one positioning element, and the test bench has a positioning groove that matches the positioning element.
