[0033] The test tool according to the embodiment of the present application, since the pantograph 3 is used for matching with the charging gun of the charging device 8, the driving device 2 can drive the pantograph 3 to act through the mounting portion 25 to adjust the position and / or angle of the pantograph 3 relative to the frame 1, so that an operator can adjust the position and / or angle of the pantograph 3 through the driving device 2 to simulate the posture of the pantograph 3 of a real vehicle, so as to test the charging device 8 by a tester, thereby reducing the testing difficulty and testing cost of the charging device 8.

[0034] It can be understood that the driving device 2 can drive the pantograph 3 to act to adjust the position of the pantograph 3 relative to the frame 1. Alternatively, the driving device 2 can drive the pantograph 3 to act to adjust the angle of the pantograph 3 relative to the frame 1. Alternatively, the driving device 2 can drive the pantograph 3 to act to synchronously adjust the position and angle of the pantograph 3.

[0035] Exemplarily, the mounting portion 25 can be a bracket structure, a plate structure or a block structure, and the present application does not limit this. When the pantograph 3 is fixed together with the mounting portion 25, the pantograph 3 and the mounting portion 25 can move synchronously.

[0036] Optionally, the driving device 2 comprises a first translation assembly 21 and a second translation assembly 22, the first translation assembly 21 is installed on the frame 1, the second translation assembly 22 is installed on the first translation assembly 21, the mounting portion 25 is installed on the second translation assembly 22, the first translation assembly 21 is used for driving the second translation assembly 22 to move in a first direction, the second translation assembly 22 is used for driving the mounting portion 25 to move in a second direction, and the first direction and the second direction have a preset included angle. In this way, the position of the mounting portion 25 in the first direction and the second direction can be adjusted through the driving device 2, so as to improve the flexibility of the position adjustment of the pantograph 3, and different types of vehicles can be adapted.

[0037] For example, the first direction and the second direction are orthogonal. In this way, the first translation assembly 21 and the second translation assembly 22 can move the shortest distance to adjust the pantograph 3 to a preset position.

[0038] In the example of the present application, the first direction can be an X direction, for example, a left-right direction of the vehicle. The second direction can be a Y direction, for example, a front-rear direction of the vehicle. In this way, the driving device 2 can drive the pantograph 3 to move in a horizontal plane through the first translation assembly 21 and the second translation assembly 22.

[0039] As shown in Figure 3 and Figure 5 , the first translation assembly 21 comprises a first guide rail 211 and a first sliding block 212, the first guide rail 211 is arranged on the frame 1, and the first sliding block 212 is arranged on the second translation assembly 22 and is in sliding fit with the first guide rail 211 in the first direction. Thus, the smoothness of the movement of the second translation assembly 22 in the first direction can be improved, and the structure design is simple and the manufacturing cost is low.

[0043] It can be understood that when it is necessary to adjust the position of the second translation assembly 22 in the first direction, the first locking piece 42 can be switched to the release position, at this time the first fixing seat 41 can move relative to the first guide rail 211 in the first direction, so that the first fixing seat 41 does not interfere with the first sliding block 212 when the position of the second translation assembly 22 is adjusted in the first direction, to ensure the smoothness of the position adjustment of the second translation assembly 22.

[0044] When it is necessary to lock the position of the second translation assembly 22, the first locking piece 42 can be switched to the locking position, at this time the first fixing seat 41 is fixed relative to the first guide rail 211, so that the first sliding block 212 can be stopped to prevent the first sliding block 212 from moving in the first direction, thereby locking the position of the second translation assembly 22.
