Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a portable charging pile multi-parameter calibration device. Background Technology

[0002] With the development of mobile internet and the Internet of Things, electric vehicle charging pile equipment has become increasingly functional, including timed charging, automatic power-off when fully charged, automatic power-off in case of abnormal current or voltage, and equipment temperature monitoring. These features can ensure charging safety to the greatest extent. Charging piles need to calculate the amount of electricity used for charging and monitor the charging current and voltage. The traditional solution is to use an electricity meter, but with the charging pile standard requiring the electricity reading to be accurate to 0.001kWh, electricity meters can no longer meet the requirements. Therefore, electricity metering verification modules have emerged.

[0003] The electricity metering verification module can complete verification items such as working error, display error, payment amount error, and clock indication error. The verification results are directly displayed in the testing software, meeting the requirements for AC power monitoring of charging piles. Currently, existing verification equipment is large and heavy, making it inconvenient to move during ground-based verification operations. Furthermore, longitudinal vibrations during ground movement can easily damage components. Therefore, this application proposes a portable multi-parameter verification device for charging piles, which solves the above problems. Utility Model Content

[0006] Optionally, a limiting groove is provided at the center of the bottom surface of the movable frame, and a limiting post is installed at the center of the top surface of the base plate, which passes through the limiting groove and the two are slidably engaged, with the spring sleeved outside the limiting post.

[0007] Optionally, the movable frame has openings on both sides of its exterior, and threaded rods are rotatably installed inside the two openings. Fixing plates are installed on both sides of the equipment mounting box, which are located in the two openings and are threadedly engaged with the two threaded rods respectively.

[0008] Optionally, a set of mounting ports is provided on both sides above the mobile frame, and a cover plate is rotatably installed on both sets of mounting ports.

[0009] Optionally, a notch is provided on one side of the exterior of both cover plates.

[0010] This utility model has the following advantages:

[0011] This portable charging pile multi-parameter calibration device uses a U-shaped mobile frame as its main body. Inside the mobile frame is a reciprocating equipment mounting box containing electrical equipment. This allows staff to adjust the vertical position of the mounting box according to actual conditions for easy use. Below the mobile frame is a reciprocating base plate with a spring between them to cushion vibrations. Rollers are installed at the four corners of the base plate to facilitate movement of the entire device.

[0012] Covers are rotatably installed on both sides above the mobile frame. These covers can close the equipment mounting box and can automatically open during the upward movement of the equipment mounting box for easy use by staff. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] like Figures 1 to 6As shown, a portable charging pile multi-parameter calibration device includes a U-shaped mobile frame 1. Inside the mobile frame 1, there is a device mounting box 2 that can move up and down. Inside the device mounting box 2, there is an electrical device 3. A base plate 6 is installed below the mobile frame 1, and a spring 8 is installed between the two. Rollers 7 are installed at the four corners of the bottom surface of the base plate 6.

[0022] As an optional technical solution of this utility model, a limiting groove 11 is opened in the middle of the bottom surface of the mobile frame 1, and a limiting post 14 is installed in the middle of the top surface of the base plate 6, which passes through the limiting groove 11 and the two are slidably engaged. A spring 8 is sleeved on the limiting post 14. The shape of the limiting post 14 and the limiting groove 11 can be polygonal, which is used to limit the movement so that the limiting post 14 can only move back and forth.

[0023] As an optional technical solution of this utility model, the movable frame 1 has openings 9 on both sides of its exterior. Threaded rods 5 are rotatably installed inside the two openings 9. Fixing plates 12 are installed on both sides of the exterior of the equipment mounting box 2. They are located in the two openings 9 and are threadedly engaged with the two threaded rods 5 respectively. In this way, the equipment mounting box 2 can move up and down by rotating the threaded rods 5.

[0024] As an optional technical solution of this utility model, a set of installation ports 10 are provided on both sides above the mobile frame 1, and a cover plate 4 is rotatably installed on both sets of installation ports 10. In this way, the equipment installation box 2 can be sealed by the two cover plates 4 to prevent soil or water from entering the equipment.

[0025] As an optional technical solution of this utility model, a notch 13 is provided on one side of the outer side of both cover plates 4, which can avoid positional interference between the cover plate 4 and the threaded rod 5, so that the cover plate 4 can be flipped normally.

[0026] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: A U-shaped movable frame 1 serves as the main body of the device. Inside the movable frame 1 is a reciprocating equipment mounting box 2, which contains electrical equipment 3.
