[0025] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0026] like Figures 1 to 4 As shown, a new energy charging gun insertion force detection device includes a base 1, two groups of support plates 2 are fixedly connected to both sides of the upper end of the base 1, two groups of outer frames 3 are fixedly connected to the front and rear ends of the support plates 2, an operation display screen 4 is arranged at the front end of one group of outer frames 3, the inside of the two groups of outer frames 3 is fixedly connected to a support frame 5, and also includes a positioning component, the positioning component includes an infrared sensor 16 arranged at the rear end of the support frame 5, two groups of slide grooves 8 are respectively arranged at the upper and lower ends of the inside of the support frame 5, two groups of moving blocks 10 are respectively slidably connected to the inside of the two groups of slide grooves 8, the upper end of the moving block 10 is fixedly connected to a moving frame 9, and the front end of the moving frame 9 is fixedly connected to a radiation signal board 15.

[0027] Specifically, Figures 1 to 3As shown, a fixed plate 6 is fixedly connected to one end of the inner part of the support frame 5, a charging port 7 is fixedly connected to the inner part of the fixed plate 6 and the support plate 2, a charging gun head 11 is fixedly connected to the inner part of the mobile frame 9, the output end of the charging gun head 11 is adapted to the input end of the charging port 7, a connecting block 12 is fixedly connected to one end of the mobile frame 9, a pushing rod 13 is fixedly connected to one end of the connecting block 12, the pushing rod 13 is transmission-connected to a pushing rod motor 14, and the pushing rod motor 14 is fixedly connected to the inner side of an outer frame 3.

[0028] When working, first start the push rod motor 14, the push rod motor 14 drives the push rod 13, and the push rod 13 drives the connecting block 12 to move along one end of the moving frame 9. Because the connecting block 12 is fixedly connected to the moving frame 9, the upper and lower ends of the moving frame 9 are respectively connected with corresponding moving blocks 10, and the moving block 10 is slidably connected to the slide groove 8, so the connecting block 12 drives the moving frame 9 to slide along the inside of the slide groove 8. Because the charging port 7 is adapted to the charging gun head 11, and the charging gun head 11 is fixed inside the moving frame 9, when the moving frame 9 moves, it drives the charging gun head 11 to be inserted into the inside of the charging port 7. When the charging gun head 11 is fully inserted into the inside of the charging port 7, the push rod motor 14 reverses and drives the push rod 13 to move along the other end of the moving frame 9, thereby disengaging the charging gun head 11 from the charging port 7, and repeats the reciprocating motion according to the program, so that the plug-in and unplug test between the charging port 7 and the charging gun head 11 is more accurate and stable, and the vibration during mechanical operation will not cause misalignment between the charging port 7 and the charging gun head 11 during plug-in and unplugging.

[0029] like Figures 1 to 4 As shown, two groups of slide grooves 8 are respectively provided at the upper and lower ends inside the supporting frame 5, and two groups of moving blocks 10 are respectively slidably connected inside the two groups of slide grooves 8. The upper ends of the moving blocks 10 are fixedly connected to the moving frames 9, and the front ends of the moving frames 9 are fixedly connected to the radiation signal board 15. The radiation signal board 15 is correspondingly arranged with the infrared sensor 16, and the signal output end of the infrared sensor 16 is electrically connected to the operation display screen 4. A pressure sensor 17 is arranged at one end of the charging port 7, and the pressure sensor 17 is arranged inside the support plate 2.

[0030] During operation, the push rod speed and number of times of the push rod motor 14 are inputted in the operation display screen 4. When the push rod motor 14 is started, the charging gun head 11 is inserted into the charging port 7. Because the radiation signal board 15 is fixed on the movable frame 9, when the charging gun head 11 moves, the radiation signal board 15 moves accordingly. After the radiation signal board 15 moves, it is parallel to the infrared sensor 16 arranged on the supporting frame 5. The infrared sensor 16 senses the radiation signal on the radiation signal board 15, and the infrared sensor 16 converts the radiation into an electrical signal. At the same time, the infrared sensor 16 transmits the number of times the electrical signal is triggered to the operation display screen 4, thereby The number of times the charging gun head 11 was inserted into the charging port 7 was recorded. At the same time, when the charging gun head 11 was inserted into the charging port 7, the insertion of the charging gun head 11 caused the pressure of the pressure sensor 17 to change. The insertion force of the charging gun was calculated by the change in the data of the pressure sensor 17 before and after the insertion of the charging gun head 11. At the same time, the changes in voltage and current when the charging gun was charging were observed during the test. The staff conducted multiple sets of charging gun insertion force tests with different parameters to determine how many times the charging gun can be stably plugged and unplugged under different insertion forces, and obtained the safe service life, while reducing the safety risks caused by overload use of the electric vehicle charging gun.
