The control panel 111 on the outside, when testing the charging pile, the present application only needs to place the device at one end of the charging area, and then unfold the shear bracket 200, so that the test component 300 corresponds to the positions of multiple charging piles, which is convenient for improving the efficiency of the test;

[0036] The other end of the shear bracket 200 is rotatably connected to an auxiliary slider 205 on the surface of the movable door 104, and the auxiliary slider 205 is slidably arranged on the auxiliary guide rod 204, and the upper end of the auxiliary guide rod 204 is connected and fixed to the surface of the movable door 104 through a fixed block. The driving component includes two driving sliders 201 arranged at the driving end of the shear bracket 200, and a driving motor 202 is fixedly arranged on the inner wall of the test cabinet 100 between the two driving sliders 201.

The end of the driving screw 203 is rotatably connected to the inner wall of the test cabinet 100. Under the drive of the driving motor 202, the driving screw 203 and the driving slider 201 rotate relative to each other. Under the action of the thread, the driving slider 201 will slide along the inner wall of the test cabinet 100, thereby driving the driving end of the shear bracket 200 to move closer or farther, so that the shear bracket 200 can provide power for the extension and retraction;

[0037] like Figure 1-7As shown, the stabilizing component includes vertical slide grooves 401 symmetrically arranged on both sides of the test cabinet 100, a downward pressing plate 415 is slidably provided on the inner wall of the test cabinet 100 where the vertical slide groove 401 is located, a downward pressing guide rod 414 is slidably provided in the vertical hole on the downward pressing plate 415, and the downward pressing guide rod 414 is connected to the top of the downward pressing guide rod 414 through a vertical spring, a downward pressing inclined plate 417 is provided at one end of the downward pressing plate 415 facing the movable door 104, and a pressing rod 417 is symmetrically provided on the inner side of the movable door 104. 08, the end of the pressure rod 408 is rotatably provided with a pressure wheel 407 matching the downward pressure inclined plate 417, the outer side of the downward pressure plate 415 is connected to the brake plate 403 through a connecting rod, and the lower end of the brake plate 403 is provided with an anti-skid layer matching the upper end of the second wheel set 106. When the movable door 104 is away from the test cabinet 100, under the action of the vertical spring, the downward pressure plate 415 drives the brake plate 403 to move downward, and the downward movement of the brake plate 403 will automatically lock the second wheel set 106, thereby preventing the test cabinet 100 from moving;

[0038] like Figure 8As shown, the stabilizing component also includes a horizontal sliding hole horizontally opened on the lower pressing plate 415, and a side sliding rod 418 is slidably arranged in the horizontal sliding hole. The outer end of the side sliding rod 418 is connected to the cross bar frame 402, and the outer end of the cross bar frame 402 is connected to the stabilizing plate 404 through an external connecting rod 406. The width of the stabilizing plate 404 corresponds to the width of the test cabinet 100. A plurality of notches are opened at the lower end of the stabilizing plate 404, and an auxiliary pulley 405 is rotatably arranged at each notch position. The inner end of the side sliding rod 418 is connected to the lower pressing plate 415. The side sliding rod 418 is connected by a side sliding spring 416, and a flip dial shaft 419 is provided on the side away from the movable door 104. A flip plate 420 is provided below the flip dial shaft 419. One end of the flip plate 420 is rotatably connected to the bottom of the test cabinet 100, and the other end of the flip plate 420 is connected to the traction rope 413. The upper end of the traction rope 413 is connected to the side connecting plate 412 on the outside of the vertical traction frame 410. The vertical traction frame 410 is slidably set on the inner wall of the test cabinet 100. The vertical traction frame 410 is located On the travel route of the driving slider 201, a vertical guide rod 409 is slidably provided in the guide holes at both ends of the vertical traction frame 410, and the lower end of the vertical guide rod 409 is connected to the support block 411 on the inner wall of the test cabinet 100. When the movable door 104 is initially away from the test cabinet 100, the vertical traction frame 410 will not be triggered. However, as the movable door 104 continues to extend, the wind resistance of the entire device is relatively large, so it is necessary to further improve the stability of the product. When the driving slider 201 moves upward, the driving slider 2 01 will generate thrust on the vertical traction frame 410, and the vertical traction frame 410 drives the flip plate 420 to flip through the side connecting plate 412 and the traction rope 413. When the flip plate 420 flips, it will generate outward thrust on the flip dial shaft 419, and the flip dial shaft 419 drives the side sliding rod 418 to slide outward. The side sliding rod 418 drives the auxiliary pulley 405 and the external rod 406 to move outward through the cross bar frame 402. In this way, the two auxiliary pulleys 405 are deployed outward, which undoubtedly increases the support area at the bottom of the equipment, thereby improving the stability of the product;

[0039] A tool box 108 for storing tools is fixedly provided on the inner side of the movable door 104, and a plurality of tool hooks 107 for hanging tools are distributed on the inner wall of the tool box 108, so that tools can be provided for maintenance of the equipment;

When it is necessary to protect the position of the shear support 200, it is only necessary to buckle the traction hook 103 in the hook hole 109 when the movable door 104 is separated from the test cabinet 100. When the movable door 104 moves, the protective roller curtain 101 will form a shielding area above the shear support 200, thereby protecting the position of the shear support 200;

[0041] like Figure 1-6 As shown, the test component 300 includes an installation box 301 rotatably connected to the shear support 200, a counterweight block 312 is provided at the bottom center of the installation box 301, under the action of the counterweight block 312, the opening of the installation box 301 will always be set upward, a storage groove 305 is provided at the upper end of the installation box 301, a performance test body 302 is provided at the position of the storage groove 305, a rotating shaft 304 is rotatably provided inside the storage groove 305, a winding groove 307 for winding a wire is provided on the rotating shaft 304, an electric connection ring sleeve 306 which is rotatably connected to one end of the winding groove 307 is rotatably provided on the outer side of the rotating shaft 304, and the winding groove The free end of 307 is provided with a power plug 310 matching the charging pile, the other end of the power ring sleeve 306 is connected to the input end of the performance test body 302, the end of the rotating shaft 304 is connected to the winding motor 308 for driving it to rotate, and the installation box 301 is also provided with a reciprocating guide unit for evenly winding the wire. In actual use, the winding motor 308 drives the rotating shaft 304 to rotate, thereby achieving the lengthening of the wire, connecting the charger through the power plug 310, and testing the charging pile through the performance test body 302. When the wire is rolled up, the reciprocating guide unit can make the wire evenly wound on the surface of the winding groove 307;

[0042] The test cabinet 100 is also provided with a heat dissipation component for cooling the test component 300, and the heat dissipation component includes a hollow shaft rotatably arranged at the intersection of the shear support 200, and an air blowing box 311 connected to the end of the hollow shaft is provided at the bottom of the installation box 301, and a plurality of air blowing holes are distributed on the upper end of the air blowing box 311, and the air blowing box 311 is located below the performance test body 302, and the other end of the hollow shaft is connected to a cache box 504, and the cache boxes 504 are connected to each other through a connecting pipe 503, and the air inlet end of the cache box 504 at the end is connected to the air supply duct 502, and the other end of the air supply duct 502 is connected to the surface of the test cabinet 100. The filter box 500 is connected, and a filter screen for filtering air is arranged inside the filter box 500. A heat dissipation fan 501 for blowing air is arranged at the air inlet end of the filter box 500. The connecting pipe 503 and the air supply duct 502 are both telescopic bellows, which are convenient for later telescoping. The gas is sent into the cache box 504 through the heat dissipation fan 501. The gas is filtered when passing through the filter box 500. The airflow enters the multiple cache boxes 504 along the connecting pipe 503, and then enters the blowing box 311 along the hollow shaft, and finally blows out from the blowing hole, thereby cooling the performance test body 302, so that the performance test body 302 can work normally;

[0043] The reciprocating guide unit includes a reciprocating roller 303 coaxially arranged on the outside of the rotating shaft 304, and a rotating groove 316 is opened on the surface of the reciprocating roller 303. Two reciprocating guide rods 315 are fixedly provided on the inner wall of the installation box 301. A reciprocating slider 314 is slidably sleeved on the reciprocating guide rod 315. The lower end of the reciprocating slider 314 is connected to the guide ring 309 through a reciprocating connecting rod 313. A guide pin 317 matching the rotating groove 316 is provided on the side of the reciprocating slider 314. The guide ring 309 is used to allow the wire to pass through. When the rotating shaft 304 rotates, the rotating groove 316 and the guide pin 317 match, so that the reciprocating slider 314 slides on the surface of the reciprocating guide rod 315. In this way, the reciprocating slider 314 will drive the guide ring 309 to move back and forth through the reciprocating connecting rod 313, so that the wire is evenly wound in the winding groove 307 position.

[0044] Working principle: In actual use, the test cabinet 100 is first fixed at one end of the charging area, and then the shear bracket 200 is unfolded, the movable door 104 will extend to one side, and the spacing of the corresponding test components 300 is adjusted according to the spacing of the charging piles, so that multiple charging piles can be tested at the same time. When the shear bracket 200 is unfolded, under the action of the vertical spring, the lower pressure plate 415 drives the brake plate 403 to move downward, and the downward movement of the brake plate 403 will automatically lock the second wheel group 106, thereby preventing the test cabinet 100 from moving;

[0045] When the driving slider 201 moves upward, the driving slider 201 will generate a thrust on the vertical traction frame 410, and the vertical traction frame 410 drives the flip plate 420 to flip through the side connecting plate 412 and the traction rope 413. When the flip plate 420 flips, it will generate an outward thrust on the flip dial shaft 419, and the flip dial shaft 419 drives the side sliding rod 418 to slide outward, and the side sliding rod 418 drives the auxiliary pulley 405 and the external rod 406 to move outward through the cross bar frame 402. In this way, the two auxiliary pulleys 405 are deployed outward, which undoubtedly increases the support area of ​​the bottom of the device;

[0046] When the position of the shear support 200 needs to be protected, the traction hook 103 is buckled in the hook hole 109 when the movable door 104 is separated from the test cabinet 100. When the movable door 104 moves, the protective roller shutter 101 will form a shielding area above the shear support 200, thereby protecting the position of the shear support 200;

[0047] The gas is sent into the cache box 504 through the heat dissipation fan 501. The gas is filtered when passing through the filter box 500. The airflow enters the multiple cache boxes 504 along the connecting pipe 503, and then enters the blowing box 311 along the hollow shaft, and finally blown out from the blowing hole, thereby cooling the performance test body 302 so that the performance test body 302 can work normally.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
