[0023] Please refer to Figure 1-4 This embodiment provides a charging seat force test device, including a base 1 and a top plate 2 arranged above the base 1, the base 1 and the top plate 2 are connected by four support columns, the base and the top plate 2 are arranged in parallel, and the base 1 is provided with a first carrier 4 for placing the charging seat female head 3. A cylinder 5 is provided on the top plate 2, and a second carrier 7 for fixing the charging seat male head 6 is provided at the output end of the cylinder 5. The output shaft of the cylinder 5 passes through the top plate 2 and is connected to the second carrier 7. The charging seat male head 6 is fixed to the second carrier 7 by screws to ensure that the charging seat male head 6 can be vertically inserted into the charging seat female head 3 downward, and the cylinder 5 provides an initial force for the force test. A pressurizing mechanism 8 is provided in the center of the first carrier 4. The pressurizing mechanism 8 includes a spring 9 fixed on the base 1. A movable block 10 is fixed to the other end of the spring 9. A gap is left between the movable block 10 and the first carrier 4 for inserting the female connector 3 of the charging socket. The movable block 10 can move in the vertical direction under the action of external force. The spring 9 is compressed for a certain stroke, thereby providing an upward extrusion force. The specific pressurizing time and number of tests are controlled by the air valve controlled by the YO and com ports of the PLC, and then the air valve controls the cylinder to execute.

[0024] When in use, the female connector 3 of the charging cradle is plugged into the movable block 10, and the cylinder 5 drives the male connector 6 of the charging cradle to be inserted into the female connector 3 of the charging cradle, and continues to squeeze the spring 9 downward for force testing. The force required in this embodiment is 300 Newtons, and the spring 9 used is a 30mm light-loaded yellow spring, and the force of 300 Newtons is obtained by compressing the spring 9 by 5mm. In this embodiment, the spring 9 is placed downward, and the spring 9 is used to directly provide upward force to the female connector 3 of the charging cradle from bottom to top, so that the force value can be accurately obtained, and the number of compressions of the spring 9 can reach 500,000 times. Compared with finished dynamometers and other equipment, it has low cost and long life.

[0025] In a preferred embodiment, limit blocks 11 are provided on both sides of the first carrier 4 . The limit blocks 11 are inverted L-shaped structures and are used to limit the female connector 3 of the charging seat in the vertical direction.

[0026] For details, please refer to Figure 2 , 3 In this embodiment, the outer side of the charging seat female connector 3 has a flange, and the inverted L-shaped structure of the limit block 11 can limit the charging seat female connector 3 on the upper side of the flange to prevent the charging seat female connector 3 from being separated from the first carrier 4 during the plugging and unplugging process, thereby improving the testing efficiency of the testing device.
