[0032] The support platform 101 is used to support the detection instrument 102, which is used to simulate various electromagnetic environments and measure the response of the on-board charger. The positioning frame 103 is used to position the on-board charger. The detection plug 104 is a plug or fixing clip at the end of the detection line, which is used to electrically connect the detection instrument 102 and the on-board charger.

[0033] The organizing component 200 is arranged on the top of the support platform 101, and includes a support member 201, a fixing member 202, a clamping member 203 and a label plate 204. The support member 201 is arranged on the top of the support platform 101, the fixing member 202 is located on the support member 201, the clamping member 203 is arranged on the support member 201, and the label plate 204 is fixed on one side of the support member 201.

[0040] The positioning block 201e is used to support the end of the pressing plate 201f. When the pressing plate 201f is located on the top of the positioning block 201e, the pressing plate 201f and the supporting plate 201b are parallel.

[0041] Example 2

[0042] Reference Figures 1 to 7 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0043] Specifically, the fixing member 202 includes a lifting sleeve 202a, a first spring 202b and a stop block 202c. The lifting sleeve 202a slides in the positioning block 201e. The two ends of the first spring 202b are respectively fixed to the inner top wall of the lifting sleeve 202a and the top of the supporting plate 201b. The stop block 202c is fixed to one side of the lifting sleeve 202a.

[0044] The first spring 202b is in a compressed state, and the lifting sleeve 202a is squeezed by the pressure plate 201f, so that the top of the lifting sleeve 202a can be pressed into the positioning block 201e. The stop block 202c can limit the lifting sleeve 202a to prevent the lifting sleeve 202a from sliding out of the positioning block 201e.

[0045] Specifically, the fixing member 202 also includes a support frame 202d, a block 202e and a second spring 202f. The support frame 202d is fixed to one side of the positioning block 201e. The block 202e is hinged in the support frame 202d. The two ends of the second spring 202f are respectively fixed to one side of the block 202e and one side of the positioning block 201e.

[0046] The support frame 202d is used to support the block 202e so that the block 202e can swing. A slot is provided on one side of the block 202e to fix the pressure plate 201f. The second spring 202f is in a compressed state. The elastic force of the second spring 202f can move the block 202e toward the positioning block 201e.

[0047] Specifically, the fixing member 202 also includes a column 202g, a pull plate 202h and a third spring 202i. The column 202g slides in the block 202e, the pull plate 202h is fixed to the end of the column 202g, and the two ends of the third spring 202i are respectively fixed to one side of the pull plate 202h and the inner wall of the block 202e.

[0048] The third spring 202i is in a stretched state. Through the pulling force of the third spring 202i, the pulling plate 202h can push the plug post 202g. When the lifting sleeve 202a drives the block 202c to move downward, the plug post 202g can be inserted into the positioning block 201e to fix the angle of the block 202e. If the lifting sleeve 202a is not squeezed by the pressure plate 201f, the plug post 202g cannot be inserted into the positioning block 201e due to the obstruction of the block 202c.

[0049] Specifically, the clamping member 203 includes a support wheel 203a, a support shaft 203b and a coil spring 203c. The support wheel 203a is arranged in the supporting plate 201b, the support shaft 203b is rotatably connected in the supporting plate 201b, the support wheel 203a is fixed on the surface of the support shaft 203b, and the two ends of the coil spring 203c are respectively fixed on the surface of the support shaft 203b and the inner wall of the supporting plate 201b.

[0050] The support wheel 203a is used to support the detection line, the support shaft 203b is used to support the support wheel 203a, and the coil spring 203c is set so that after the detection line drives the support wheel 203a to rotate, the support wheel 203a can drive the detection line to reset and move through the reset ability of the coil spring 203c.

[0051] Specifically, the clamping member 203 also includes a lifting frame 203d, an extrusion wheel 203e, a threaded shaft 203f, a support plate 203g and a drive sleeve 203h. The lifting frame 203d slides in the pressure plate 201f, the extrusion wheel 203e is rotatably connected to the lifting frame 203d through a rotating shaft, the threaded shaft 203f is fixed to the top of the lifting frame 203d, the support plate 203g is fixed to the top of the pressure plate 201f, the drive sleeve 203h is rotatably connected to the support plate 203g, and the drive sleeve 203h is rotatably connected to the surface of the threaded shaft 203f through a thread.

[0052] The lifting frame 203d is used to support the extrusion wheel 203e, and the extrusion wheel 203e is used to squeeze the detection line on the top of the support wheel 203a, so that there is sufficient friction between the support wheel 203a and the detection line to prevent sliding between the support wheel 203a and the detection line. By rotating the driving sleeve 203h, the threaded shaft 203f can be driven to move up and down, thereby driving the extrusion wheel 203e to approach or move away from the detection line, so that the extrusion wheel 203e and the support wheel 203a can clamp detection lines of different diameters.

[0053] During use, when the detection line needs to be arranged, the detection line can be placed on the supporting wheel 203a of the supporting plate 201b, and then the pressing plate 201f is rotated toward the supporting plate 201b, so that the end of the pressing plate 201f squeezes the block 202e, causing the block 202e to swing. When the pressing plate 201f falls on the top of the positioning block 201e, the elastic force of the second spring 202f can make the block 202e clamped on the end of the pressing plate 201f, thereby fixing the pressing plate 201f. At the same time, under the pulling force of the third spring 202i, the plug 202g will be inserted into the positioning block 201e, thereby fixing the position of the block 202e. At this time, the driving sleeve 203h can be rotated to adjust the squeezing force of each squeezing wheel 203e on the detection line, so that there is sufficient friction between the support wheel 203a and the detection line to prevent sliding between the support wheel 203a and the detection line. Then, the identification label is pasted on the label plate 204 to facilitate the staff to distinguish the purpose of each detection line.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
