DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figure 1-Figure 5 A portable AC charging pile measurement and calibration device in one embodiment of the present invention includes a shell component 1, wherein the shell component 1 includes a main shell 101, a shield cover 102 and a rotating wheel 103, wherein the shield cover 102 is rotatably assembled on the main shell 101, and the main shell 101 is further equipped with a rotating wheel 103 at one end away from the shield cover 102; a pull rod assembly 2, wherein the pull rod assembly 2 includes a slide groove 201 and a folding handle 202, wherein the slide groove 201 is arranged on one side of the main shell 101, and the folding handle 202 is slidably inserted in the slide groove 201, and the slide groove 201 is arranged near the side of the rotating wheel 103; The calibration equipment component 3 includes a mounting base 301, which is movably arranged in the main shell 101, and a number of side arms 302 are circumferentially arranged on the mounting base 301; and a rotating shock filtering mechanism 4, which includes a fixed wheel groove 401, a rotating wheel 402 and an elastic member 406, and the fixed wheel groove 401 is fixedly assembled on the inner wall of the main shell 101, and the rotating wheel 402 is rotatably assembled in the fixed wheel groove 401, and the rotating wheel 402 is elastically assembled on the rotating wheel 402, and the connecting block 407 is movably connected to the side arm 302.

[0026] In actual application of this embodiment, when the portable AC charging pile measurement and calibration device is used, the shield cover 102 at one end of the device is rotated and fastened to the main shell 101 in the non-working state, so as to seal and protect the main shell 101, and since the other end of the main shell 101 is equipped with a rotating wheel 103 and a pull rod assembly 2, when the staff needs to move between charging piles, they can pull the folding handle 202 on one side of the main shell 101 to pull the main shell 101 to move on the ground, and after moving to one side of the charging pile, the device can be placed horizontally on the ground with the mounting base 301 assembled therein placed facing upward, so that the equipment on the mounting base 301 can be used to calibrate the AC charging pile, which has excellent flexibility and convenience, and when the measurement and calibration device is moving on the ground, since the mounting base 301 is connected to the rotating shock filtering mechanism 4 through a number of side arms 302 , and the fixed wheel groove 401 is fixedly assembled on the inner wall of the main shell 101, and the swivel wheel 402 is rotatably installed in the fixed wheel groove 401 and elastically connected to the connecting block 407, so that when the main shell 101 in the device is manually dragged and placed horizontally for calibration, the gravity of the mounting base 301 itself acts on several connecting blocks 407 through the side support arm 302, and by pressing the connecting block 407, the swivel wheel 402 is driven to rotate in the fixed wheel groove 401, so that the guide rod 405 on one side of the connecting block 407 rotates downward in the vertical direction, so that when the calibration device is carried and moved, when the angle between the main shell 101 and the ground changes, the guide rod 405 in the several swivel wheels 402 thereon always rotates in the vertical direction, so that it has a vertical shock filtering effect, avoiding the calibration equipment from being damaged by vertical vibration when the device is tilted and dragged, thereby improving its protection effect and extending its service life.

[0027] See also Figure 1 In a preferred embodiment of the present invention, the shell component 1 further includes a support wheel 104, which is arranged at one end of the main shell 101 and located on the side of the end face where the rotating wheel 103 is located, and the support wheel 104 is arranged close to the side of the folding handle 202.

[0028] In actual application of this embodiment, the support wheels 104 can serve as auxiliary support when the main shell 101 is placed horizontally on the ground, and can also be replaced by pads. However, considering that in actual use, the calibration equipment needs to move short distances between multiple groups of charging piles, it is preferred to use support wheels 104.

[0029] See also Figure 1In a preferred embodiment of the present invention, the calibration equipment component 3 also includes a vehicle socket slot 303, a charging pile slot 304, a display screen 305 and a control key 306. The vehicle socket slot 303 and the charging pile slot 304 are fixedly assembled on the mounting base 301, and the mounting base 301 is also provided with a display screen 305 and a control key 306.

[0030] In actual application of this embodiment, the vehicle socket slot 303 and the charging pile slot 304 adopt the national standard charging gun socket by default, and the pin definition meets the requirements of the national standard; the display screen 305 preferably adopts an embedded integrated touch screen and is installed with the corresponding verification software. No specific restrictions are made here on the voltage and current measurement accuracy of the verification software.

[0031] See also Figure 4 In a preferred embodiment of this embodiment, the rotating shock filtering mechanism 4 also includes balls 403, and a plurality of balls 403 are assembled between the fixed wheel groove 401 and the rotating wheel 402 so that the rotating wheel 402 of the fixed wheel groove 401 rotates and connects.

[0032] In actual application of this embodiment, the fixed wheel groove 401 and the rotating wheel 402 can be connected to each other by ball bearings or roller bearings. However, considering the influence of the weight of the calibration equipment, the load-bearing capacity of roller bearings under load conditions is lower than that of ball bearings. When there is a large deflection torque, it is preferred to use ball bearings arranged between the fixed wheel groove 401 and the rotating wheel 402.

[0033] See also Figure 3 and Figure 4 In a preferred embodiment of the present invention, the rotating shock filtering mechanism 4 further includes a crossbeam 404 and a guide rod 405.

The end of the crossbeam 404 is fixedly connected to the connecting block 407, and the crossbeam 404 and the connecting block 407 are elastically connected through an elastic member 406; the side support arm 302 is eccentrically arranged with the rotary wheel 402.

[0034] In actual application of this embodiment, since the side support arm 302 and the rotating wheel 402 are eccentrically arranged, when the weight of one side of the mounting base 301 is pressed on the connecting block 407 through the side support arm 302, the connecting block 407 can drive the rotating wheel 402 to rotate in the fixed wheel groove 401 to balance the torque, thereby realizing the rotation of the guide rod 405, so that the guide rod 405 and the elastic member 406 rotate in the vertical direction, thereby realizing the shock-absorbing and buffering effect in the vertical direction, so that the main shell 101 of the calibration device can filter shock at various tilt angles.

[0035] See also Figure 1 In a preferred embodiment of the present invention, the portable AC charging pile measurement and calibration device further includes a buffer air bag 5 , which is arranged between the main shell 101 and the mounting base 301 to limit the movement range of the mounting base 301 .

[0036] In actual application of this embodiment, the buffer air bag is arranged between the main shell 101 and the mounting base 301, so that the mounting base 301 is circumferentially covered in the buffer air bag 5, which can serve the purpose of auxiliary buffering, and at the same time can reduce the impact of lateral shaking on the calibration equipment and improve its pressure resistance.

[0037] The above-mentioned embodiment of the present invention provides a portable AC charging pile measurement and calibration device, and through a number of fixed wheel grooves 401 and a rotating wheel 402 circumferentially arranged in the main shell 101, and a connecting block 407 elastically connected to the rotating wheel 402, when the calibration equipment is dragged at various inclination angles, the connecting block 407 automatically tends to the vertical direction for vibration filtering, which can improve the protection effect of the calibration equipment.
