DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 6 In an embodiment of the present invention, a multifunctional manual trolley-type device includes a trolley body 10, a docking panel 20 installed at one end of the trolley body 10, and a detachable and replaceable transfer tray 30 installed on the trolley body 10; the transfer tray 30 is used to replaceably transfer and fix a product to be tested 60, so that the product to be tested 60 forms a circuit connection with the docking panel 20 through the transfer cooperation of the transfer tray 30; the docking panel 20 is used to dock with the storage position plug-in end of an external testing device, thereby realizing a circuit connection with the testing device.

[0024] Specifically, the batteries of new energy vehicles usually need to be charged and discharged with large currents, and all currents must eventually be transmitted through the battery adapter. Therefore, during the production process, the battery adapter needs to be subjected to aging tests, such as testing its aging performance when passing large currents. In order to improve the efficiency of the aging test of the battery adapter and avoid the idling energy consumption of the aging test device, it is necessary to reduce the time the battery adapter is connected to the aging test device and the time it is disconnected from the device.

[0025] Therefore, multiple groups of manual trolley-type equipment can be set up. For example, the battery adapters of the second, third, and Nth groups of trolley equipment can be installed and fixed by using the gap when the first group of trolley equipment is being tested. At the same time, a docking panel 20 is set at one end of the trolley equipment. The docking panel 20 can be used to quickly connect the trolley equipment to the aging test device to improve its efficiency in getting on and off the machine.

[0026] Secondly, the quick docking panel 20 provided on the trolley equipment can be used to quickly exit the machine after the first set of trolley equipment is tested, and then the second set of trolley equipment can be quickly pushed into the test device so that the docking panel 20 can be quickly inserted into the corresponding storage position of the test device. The plug-in end realizes quick docking and reduces the time for getting on and off the machine.

[0027] Thirdly, a set of trolley equipment can be used to install multiple products to be tested 60, thereby increasing its carrying capacity and further improving the test efficiency. In order to improve the versatility and compatibility of the trolley equipment, a detachable and replaceable transfer tray 30 can be provided on the trolley body 10. Using transfer trays 30 of different specifications, multiple models of products to be tested 60 can be transferred and fixed, thereby reducing the test cost and improving the test efficiency.

[0028] like Figures 1 to 3 As shown, preferably, the docking panel 20 is provided with an AC plug-in connector 21, and the adapter tray 30 is provided with a three-phase hand-plug assembly 31, one end of the three-phase hand-plug assembly 31 is electrically connected to the AC plug-in connector 21, and the other end thereof is electrically connected to the product to be tested 60.

[0029] Specifically, the motor on the new energy vehicle is usually a three-phase motor, so the product to be tested 60 is provided with a three-phase terminal 61 electrically connected to the three-phase motor. In order to perform an aging test on the product to be tested 60 and the three-phase terminal 61, it is necessary to set a corresponding three-phase AC plug connector 21 on the docking panel 20, and then electrically connect it to the three-phase terminal 61 of the product to be tested 60 through copper wire. In order to facilitate disassembly and connection, it is preferred to set a three-phase hand plug assembly 31 on the adapter tray 30 so that it can electrically connect the three-phase plug connector of the docking panel 20 with the three-phase terminal 61 of the product to be tested 60 through corresponding copper wires.

[0030] Secondly, new energy vehicles usually need to be equipped with a traction motor (TM), which is responsible for converting electrical energy into mechanical energy to drive the vehicle. A generator motor (GM) can also be set up to convert mechanical energy into electrical energy, usually for power generation or energy recovery. Therefore, two sets of three-phase terminals 61 are usually set on the product to be tested 60, and two sets of three-phase hand plug assemblies 31 need to be set on the transfer tray 30, and two sets of AC plug connectors 21 need to be set on the docking panel 20, so that the two three-phase terminals 61 with different uses of the product to be tested 60 can be aged separately.

[0031] like Figure 4 As shown, preferably, the three-phase hand-inserted assembly 31 is provided with a three-phase copper busbar 32 and a three-phase clamp 33, the three-phase copper busbar 32 is fixedly connected to the transfer tray 30 through an insulating plate, one end of which is electrically connected to the product to be tested 60, and the other end forms a free end; one end of the three-phase clamp 33 is electrically connected to the AC plug connector 21, and the other end of the three-phase clamp 33 can be detachably clamped on the free end of the three-phase copper busbar 32, thereby forming an electrical connection.

[0032] Specifically, in order to facilitate the corresponding replacement of the adapter tray 30 according to the different specifications of the tested products 60 and improve its docking speed, a three-phase hand-insertion assembly 31 can be set, and the detachable three-pair clamp 33 can be used to quickly unplug or connect the corresponding adapter tray 30.

[0033] like Figure 5 As shown, preferably, the three-phase hand-insertion assembly 31 is also provided with a limiting device 34 and a hand-insertion cover plate 35, the limiting device 34 is fixedly connected to the transfer tray 30, and forms a limiting groove, the three-phase clamp 33 is fixedly connected to the hand-insertion cover plate 35, and the hand-insertion cover plate 35 is detachably connected to the limiting groove, so that a clamping abutment state is formed between the three-phase clamp 33 and the three-phase copper busbar 32, and an electrical connection is formed between the two.

[0034] Specifically, the transfer tray 30 is further provided with a guide column 36 at a position corresponding to the hand-inserted cover plate 35, and the hand-inserted cover plate 35 is further provided with a guide hole 37 at a position corresponding to the guide column 36, so that when the hand-inserted cover plate 35 is pushed into the limiting groove, it can be sleeved on the guide column 36 through the guide hole 37 to achieve a precise pushing operation, so that a clamping abutment state is formed between the three-phase copper busbar 32 and the three-phase clamp 33, and an electrical connection is formed.

[0035] like Figure 2 and Figure 3 As shown, preferably, it also includes a DC connector 12, which is fixed to the frame 11 of the trolley body 10, and the docking panel 20 is also provided with a floating socket 22; one end of the DC connector 12 is electrically connected to the DC terminal 62 of the product to be tested 60, and the other end thereof is electrically connected to the floating socket 22.

[0036] Specifically, the energy storage device on the new energy vehicle is usually an energy storage battery, which can provide direct current. Therefore, a DC terminal 62 electrically connected to the energy storage battery is provided on the product to be tested 60. In order to perform an aging test on the product to be tested 60 and the DC terminal 62, a corresponding DC floating socket 22 needs to be provided on the docking panel 20, and then electrically connected to the DC terminal 62 on the product to be tested 60 through a copper wire. For the convenience of connection, it is preferred to provide a DC connector 12 on the vehicle frame 11 so that the floating socket 22 of the docking panel 20 and the DC terminal 62 of the product to be tested 60 can be electrically connected through corresponding copper wires.

[0037] like Figure 3 As shown, preferably, it also includes a resolver simulator 50, a first aviation plug 51 and a second aviation plug 52 respectively fixed to the trolley body 10, one end of the first aviation plug 51 is electrically connected to the resolver simulator 50, and the other end thereof is electrically connected to the low-voltage terminal 63 of the product under test; one end of the second aviation plug 52 is electrically connected to the low-voltage terminal 63 of the product under test, and the other end thereof is electrically connected to the floating socket 22.

[0038] Specifically, in actual operation, new energy vehicles control the speed of the vehicle through the accelerator pedal. By the different angles of the user's foot stepping on the accelerator pedal, a corresponding signal is provided, so that the electronic control system outputs a corresponding current according to the corresponding signal, so that the motor rotates at a corresponding speed to reach a corresponding vehicle speed. In order to optimize the aging test of the product to be tested 60, a resolver simulator 50 can also be set to simulate the function of the angle change of the vehicle accelerator pedal, thereby testing the transmission performance of different currents under different resolver parameters.

[0039] Secondly, in order to optimize the connection and separation methods, two aviation plugs can be set on the frame 11, so that they are electrically connected to the low-voltage terminal 63 and the floating socket 22 of the product under test respectively, so that the corresponding signal of the resolver simulator 50 is connected to the inside of the aging test device, so that it can perform corresponding aging tests on the product under test.

[0040] like Figure 2 and Figure 3 As shown, preferably, the trolley body 10 is also provided with an extension terminal 40, which is fixed to the frame 11 of the trolley body 10, one end of which is electrically connected to the floating socket 22, and the other end of which is detachably abutted against the transfer tray 30, thereby achieving electrical connection with the transfer tray 30.

[0041] Specifically, in order to test different parameters of the products 60 to be tested of various specifications, models, and layouts, an extension terminal 40 may be provided, and the extension terminal 40 may be used to further expand the various tests of the products 60 to be tested. That is, multiple terminals may be reserved for the products 60 to be tested subsequently.

[0042] like Figure 4 As shown, preferably, the transfer tray 30 is provided with a grounding probe 41 and a temperature control probe 42, the grounding probe 41 is fixedly connected to the transfer tray 30, one end of which is electrically connected to the extension terminal 40, and the other end of which is abutted against the product under test, for grounding the product under test; the temperature control probe 42 is fixedly connected to the transfer tray 30, one end of which is electrically connected to the extension terminal 40, and the other end of which is abutted against the product under test, for measuring the temperature of the product under test.

[0043] Specifically, when the product to be tested is mounted on the transfer tray 30, a corresponding probe can be set to detect the parameters of the product to be tested. For example, a temperature probe in an existing product can be set to test the surface temperature of the product to be tested 60, and the temperature is fed back to the aging test device through the extension terminal 40 for corresponding automatic control. In addition, in order to improve safety, a grounding probe 41 can also be used to ground the metal part of the product to be tested 60.

[0044] like Figures 1 to 3 As shown, preferably, the docking panel 20 is also provided with a quick connector 23, and the trolley body 10 is also fixedly connected with a pipe adapter 13, one end of the pipe adapter 13 is connected to the quick connector 23, and the other end thereof is connected to the coolant interface 64 of the product under test, so that the coolant passes through the quick connector 23, the pipe adapter 13 and the coolant interface 64 of the docking panel 20 in sequence, and enters the interior of the product under test for cooling operation.

[0045] Specifically, since the tested product needs to transmit a large current inside, and even needs to convert DC to AC, the heat generated is relatively large, so it is necessary to set up a corresponding coolant for cooling operation. In the aging test, it is also necessary to introduce a corresponding coolant for testing. Therefore, a quick connector 23 can be set on the docking panel 20 to connect the corresponding coolant from the aging test device. It can be understood that in order to form a loop, the quick connector 23, the pipe adapter 13 and the coolant interface 64 all need to be set in a pair, one of which is used for water inlet operation and the other is used for water outlet operation.

[0046] In addition, the quick connector 23 preferably adopts a drip-free quick connector 23 in existing products, so that during the docking and separation of the trolley equipment with the aging test device, the coolant will not drip from the quick connector 23, eliminating the risk of water leakage.
