[0036] As Figures 1 - 6As shown in the figure, an electrical performance test tooling for a motor controller, which includes a frame body, a tray 200 for carrying the controller 400, and several copper columns 310 for energized testing. Among them, a bottom plate 110 is provided at the bottom of the frame body, and a top plate 130 is provided at the top. The bottom plate 110 and the top plate 130 are supported by a frame 120; the bottom plate 110 extends outside the frame body, and a guide rail 111 is provided thereon, and the guide rail 111 extends from inside the frame body to outside the frame body; a lifting device is provided on the top plate 130. The tray 200 can slide into the frame body from outside the frame body along the guide rail 111 to reach the test position, and can slide from the test position to outside the frame body. The copper columns 310 are fixed on the lifting device through an assembly structure 320 and are driven by the lifting device to move up and down; several copper columns 310 can move away from the controller 400 by rising and contact the controller 400 by descending, and are electrically connected to the controller 400.

[0037] The electrical performance test tooling for the motor controller provided in this embodiment drives the copper columns 310 for energized testing to move up and down through the lifting device, and the tray 200 is used to carry the controller 400, so that it can move back and forth between the positions below the copper columns 310 and on the side of the copper columns 310 along the guide rail 111. It not only cancels the repeated installation and removal of bolts between the power supply and the controller 400 during the traditional controller 400 test, but also makes the replacement of the controller 400 more convenient and the test efficiency higher.

[0038] Specifically, in this embodiment, the frame 120 can be composed of multiple vertical columnar structures, and horizontal columns can be added at the bottom and sides of the frame 120 to strengthen the mechanical strength of the frame 120. Of course, in other embodiments, other structures, such as plates, can also be used to form the frame 120.

[0039] The lifting device can adopt existing cylinders 340, etc. In other embodiments, other linear displacement structures, such as electric push rods, can also be selected according to needs. Taking the cylinder 340 as an example of the lifting device, a solenoid valve 530 for starting the air pressure switch of the cylinder 340 and a pressure regulating valve 540 for adjusting the air pressure are also provided on this tooling; an air pipe 541 is connected to the pressure regulating valve 540, the solenoid valve 530 and the cylinder 340 in sequence to convey the gas required by the cylinder 340.

[0040] As a preferred solution, the electrical performance test tooling for the motor controller provided in this embodiment further includes a first microswitch 113 and a second microswitch 510. Among them, the first microswitch 113 is located inside the frame body and can start the downward movement of the lifting device by contacting the first microswitch 113 when the tray 200 reaches the test position; the second microswitch 510 is located below the assembly structure 320 and can start the test circuit by contacting the second microswitch 510 when the tray 200 reaches the test position. The settings of the first microswitch 113 and the second microswitch 510 can realize the automatic connection between the step of the tray 200 entering the test position and the step of the copper column 310 moving downward for testing.

[0041] Furthermore, in this embodiment, a fixing plate 500 can be further provided inside the frame body, and the second microswitch 510 is arranged on the fixing plate 500; a touch plate 324 is fixed on the assembly structure 320, and the touch plate 324 is located above the second microswitch 510 and can contact the second microswitch 510 after descending, and the test circuit is started by the second microswitch 510. The above solenoid valve 530 and pressure regulating valve 540 can both be arranged on the fixing plate 500.

[0042] In addition, the electrical performance test tooling for the motor controller provided in this embodiment further includes a jack 550, and the type of the jack 550 can be selected according to needs. Exemplarily, in this embodiment, the jack 550 can be selected as a DB9 jack 550.

[0043] In the electrical performance test tooling for the motor controller provided in this embodiment, a positioning block 210 for defining the position of the controller 400 is arranged on the outer periphery of the tray 200. Exemplarily, the bottom space of the controller 400 can be framed by an L-shaped structure at the four corners of the tray 200, so as to define the position of the controller 400 and prevent it from moving. Preferably, sliders 240 adapted to the guide rails 111 are arranged at the bottom of the tray 200, and the number of the guide rails 111 and the number of the sliders 240 can both be selected according to needs. A handle 230 for pulling can also be arranged on the tray 200.

[0044] As a preferred solution, in this embodiment, a first limit block 112 can be further arranged on the bottom plate 110, and a second limit block 250 is arranged at the bottom of the tray 200. The tray 200 can limit the distance of its outward movement from the frame body by abutting against the first limit block 112 through the second limit block 250, so as to prevent the tray 200 from slipping off the bottom plate 110. It can be imagined that the moving distance of the tray 200 can ensure that it completely moves outside the test position, so as to facilitate the tester to replace the controller 400.

[0045] Further, in this embodiment, a first positioning member 220 may be provided on the tray 200, and a second positioning member 520 may be provided on the inner side of the frame, more specifically, on the fixing plate 500, so that when the tray 200 moves towards the test position, the first positioning member 220 can limit the horizontal position of the tray 200 by plugging into the second positioning member 520. Specifically, the first positioning member 220 and the second positioning member 520 may be set as a U-shaped block and a separate clamping block adapted to the U-shaped block as shown in Figure 2 and Figure 4 . In other embodiments, they may also be set as jacks and inserting rods adapted to the jacks respectively.

[0046] In this embodiment, the assembly structure 320 includes an assembly plate 323 fixed to the lifting device, a wire box 322, and an assembly body 321. Among them, the assembly plate 323 is fixed to the lifting device and is driven by the lifting device to move up and down; the wire box 322 and the assembly body 321 are sequentially fixed below the assembly plate 323; the copper columns 310 are fixed to the assembly body 321, and the upper ends of the copper columns 310 extend into the wire box 322 and are connected to the wire harness 330 for power supply. Specifically, both the assembly body 321 and the wire box 322 are made of insulating materials such as bakelite. As a preferred solution, a wire passing hole 3221 may be provided on the wire box 322 to facilitate the passage of the wire harness 330; or the wire box 322 may be directly made of a three-dimensional frame structure.

[0047] Further, in this embodiment, the copper columns 310 are divided into DC copper columns 310 and AC copper columns 310, and the assembly composed of the wire box 322 and the assembly body 321 is divided into a DC assembly and an AC assembly. The DC copper columns 310 are fixed to the DC assembly, and the AC copper columns 310 are fixed to the AC assembly; both the DC assembly and the AC assembly are detachably connected to the assembly plate 323 and can be replaced or repaired as needed. As shown in Figure 2 and Figure 6 , the relatively longer copper columns 310 are DC copper columns 310, and the relatively shorter copper columns 310 are AC copper columns 310, which match the type of the N-type permanent magnet synchronous motor controller 400 shown in the figure.

[0048] When the motor controller electrical performance test tooling provided in this embodiment works, the tray 200 is pulled out, the controller 400 is placed on the tray 200. When the tray 200 and the controller 400 are pushed back, the first microswitch 113 is triggered, the cylinder 340 starts to move, the copper columns 310 contact the controller 400, and the second microswitch 510 is triggered to start the test. After the test is completed, the cylinder 340 retracts the stroke, and the tray 200 is pulled out to remove the controller 400.

[0049] Note: If not specifically stated, the fixed connection methods described in the text are selected from existing fixed connection methods such as threaded connection, welding, and bonding.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
