The detection table 2 is fixedly installed on the frame 1 and is located below the cantilever rod 4. The detection table 2 has a placement surface for placing the new energy charging gun 7. The electromagnetic device 5 can adsorb the metal impact detector 6 or release the metal impact detector 6 to make the metal impact detector 6 fall and impact the new energy charging gun 7 on the detection table 2. Figure 7 The new energy charging gun 7 placed on the detection table 2 in the figure is only for illustrative purposes and cannot limit the model or structure of the new energy charging gun adapted by the detector. The detector of the present application can adapt to the strength and safety detection of the outer shells of new energy charging guns of various models and structures.

By adjusting the height of the metal impact detector 6 by the lifting device 3 and adjusting the position of the metal impact detector 6 on the cantilever rod 4, the impact range and falling height of the metal impact detector 6 are effectively expanded, making the detector more adaptable to non-standard-shaped charging guns and having better compatibility.

[0053] As a preferred embodiment of the present application, as Figures 1 to 3 shown, the detection table 2 includes a lower flat plate 21 and a support plate 22 fixed above the lower flat plate 21. The top surface of the support plate 22 is the placement surface.

The impact detector further includes a cable tie, and the cable tie cooperates with the fixing holes 23 to be able to tie and fix the new energy charging gun 7 on the placement surface. Those skilled in the art can understand that the detection table 2 is a double-layer plate structure composed of the lower flat plate 21 and the support plate 22 stacked together, with higher overall strength and better impact resistance. The lower flat plate 21 can be connected to the frame 1 to form a support platform, providing stable support for the support plate 22 and the new energy charging gun 7.

When tying, the cable tie is looped above the charging gun, and the two ends of the cable tie extend through the two fixing holes 23 to the bottom of the detection table 2 and are tied together or tied to the frame 1.

[0054] As a preferred embodiment of the present application, as Figure 4 shown, a sliding seat 8 is installed on the cantilever rod 4, and the electromagnetic device 5 is arranged on the sliding seat 8. The sliding seat 8 slides along the length direction of the cantilever rod 4 to drive the electromagnetic device 5 to move. Those skilled in the art can understand that by driving the electromagnetic device 5 to move by sliding the sliding seat 8 along the length direction of the cantilever rod 4, the convenience of switching the position of the electromagnetic device 5 on the cantilever rod 4 is improved, and within the range where the metal impact detector 6 can impact the charging gun, the sliding seat 8 can switch the electromagnetic device 5 to any position on the cantilever rod 4, so as to increase as much as possible the parts of the new energy charging gun 7 that the metal impact detector 6 can impact and detect, and improve the detection quality. Specifically, the sliding seat 8 can be designed as a U-shaped structure, and the two side walls of the U-shaped structure are slidably connected to both sides of the cantilever rod 4, and the electromagnetic device 5 is fixed on the bottom wall of the U-shaped structure.

The limiting member 9 can be a metal member fixed to the end of the cantilever rod 4 by bolts, with high strength and strong limiting ability.

[0056] As a preferred embodiment of the present application, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the lifting device 3 includes a driving motor 31 and a lead screw-nut kinematic pair driven by the driving motor 31.

The upper end of the lead screw 32 of the lead screw-nut kinematic pair is connected to the output shaft of the driving motor 31, and the lower end of the lead screw 32 is rotatably connected to the frame 1. The nut 33 of the lead screw-nut kinematic pair is used to drive the cantilever rod 4 to move up and down. Specifically, during operation, the driving motor 31 is controlled to be energized and operate to drive the lead screw 32 to rotate. The rotational motion of the lead screw 32 is converted into the linear motion of the nut 33 along the lead screw 32, thereby driving the cantilever rod 4 to move up and down. Specifically, the driving motor 31 can be fixed to the frame 1 by bolts and is located above the lead screw 32. The lead screw 32 is vertically arranged. The upper end of the lead screw 32 is connected to the output shaft of the driving motor 31, and the lower end can be rotatably connected to the frame 1 through a bearing.

[0057] Further, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the impact detector further includes a nut seat 100. The nut 33 and the cantilever rod 4 are respectively fixed to the nut seat 100. Sliders 200 are provided on both sides of the nut seat 100, and slide rails 300 are provided on the frame 1. The sliding fit between the sliders 200 and the slide rails 300 guides the lifting movement of the nut 33. Specifically, the nut 33 can be fixedly connected to the nut seat 100 by bolts, and the cantilever rod 4 can be welded to the nut seat 100 to enhance the connection strength. When the nut 33 moves up and down under the drive of the driving motor 31, the sliders 200 slide along the slide rails 300 to guide the lifting movement of the nut 33, improving the reliability and stability of driving the cantilever rod 4 to move up and down.

[0058] Further, as Figure 4 and Figure 5 shown, the nut seat 100 is provided with an installation channel 101 that penetrates up and down. The nut 33 is fixed in the installation channel 101, and the cantilever rod 4 is provided with an avoidance hole 41 for the lead screw 32 to penetrate up and down. Through this setting, it helps to improve the structural compactness of the lifting device 3 and the balance of force, ensuring the stable operation of the whole machine. To avoid interference of the cantilever rod 4 with the rotation of the lead screw 32, the diameter of the avoidance hole 41 should be larger than the outer diameter of the lead screw 32 to prevent the cantilever rod from contacting the lead screw 32.

[0059] As a preferred embodiment of the present application, as Figure 1 and Figure 6As shown, the frame 1 includes a bottom frame 11 and a vertical frame 12 erected on one side of the bottom frame 11.

The wire mesh surrounds the left and right sides and the rear side of the whole machine, and the front door 14 is provided on the front side. The front door 14 can be hinged and installed on the frame 13 on one side. Those skilled in the art can understand that the setting of the protective fence can intercept and limit the falling metal impact detection piece 6, so that it is limited within the protective fence, preventing the metal impact detection piece 6 from running outside the detector. After the detection is completed, only need to open the front door 14 to take out the metal impact detection piece 6 from within the protective fence, improving the operation convenience.

[0061] As a preferred embodiment of the present application, as Figure 1 shown, a touch display screen 400 for controlling the lifting device 3 and the electromagnetic device 5 is installed on the frame 1, so that the operator can directly control the lifting of the lifting device 3 and the power on and off of the electromagnetic device 5 through the touch display screen 400, improving the operation convenience.
