Description

Technical Field

[0001] This utility model relates to the technical field of sealing test devices, specifically a sealing test device for the outer shell of a new energy vehicle charging pile. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the popularity of new energy vehicles is rising year by year. Charging facilities for new energy vehicles, especially charging piles, have become an important part of infrastructure construction. During use, charging piles need to withstand various environmental factors, such as rain, dust, and extreme temperatures. Therefore, the sealing performance of the charging pile casing is crucial to ensure the safe and stable operation of internal electronic components.

[0003] Traditional sealing performance testing methods typically employ simple water immersion tests or air pressure tests. However, these methods have limitations. Water immersion tests may damage the electronic components inside the charging pile, while simple air pressure tests may not accurately detect minute leaks. Existing testing equipment is insufficient in terms of testing accuracy and reliability. For example, gas leaks may occur during testing due to insufficient sealing of connections, making it difficult to meet the testing requirements for high precision and high reliability. Therefore, a sealing testing device for the outer shell of new energy vehicle charging piles is proposed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sealing test device for the outer shell of a new energy vehicle charging pile includes a base, on which a handle, an air pump and a support frame are arranged from left to right. The air pump is equipped with a detection component, and the front of the support frame is equipped with a control panel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 The sealing test device for the outer shell of a new energy vehicle charging pile in this embodiment includes a base 1. From left to right, a handle 2, an air pump 3 and a support frame 4 are arranged on the base 1. The air pump 3 is equipped with a detection component 5, and the front of the support frame 4 is equipped with a control panel 6.

[0023] In this embodiment, universal wheels are rotatably connected to the four corners of the lower surface of the base 1, which facilitates the portable movement of the device.

[0024] Please see Figures 2 to 3 In this embodiment, the detection component 5 includes a fixed pipe 501 connected to the output end of the air pump 3. The fixed pipe 501 is equipped with an electromagnetic valve 502. The fixed pipe 501 is located inside the support frame 4. The right side of the fixed pipe 501 is connected to the first movable hose 503. The right side of the first movable hose 503 is rotatably connected to the insertion pipe 504 through a sealed bearing. The insertion pipe 504 is equipped with a pressure sensor 505. The pressure sensor 505, the electromagnetic valve 502 and the air pump 3 are all electrically connected to the control panel 6 through wires. The outside of the insertion pipe 504 is equipped with a connector.

[0025] Specifically, the connector includes a fixing plate 506 fixed to the outside of the insertion tube 504, a vacuum pump 507 fixed on the support frame 4, and a limiting ring 508 and a rubber sealing ring 509 adapted to the insertion tube 504 fixed to the outside of the insertion tube 504. The rubber sealing ring 509 is fixed to the right side of the limiting ring 508.

[0026] Specifically, the connector also includes four fixing holes that pass through the right side of the fixing plate 506. Each of the four fixing holes has a fixing cylinder 510 fixed inside. Each of the four fixing cylinders 510 has a suction cup 511 connected to its right side. Each fixing cylinder 510 is connected by a pipe. The input end of the vacuum pump 507 is connected to the upper surface of the rear upper fixing cylinder 510 through a second flexible hose. Both the upper and lower surfaces of the fixing plate 506 are fixed with handles. The right side of the support frame 4 is provided with a hook. The handles fixed to the upper surface of the fixing plate 506 can be hung on the outside of the hooks.

[0027] Specifically, the control panel 6 is electrically connected to the vacuum pump 507 via wires, and four fixed cylinders 510 are arranged in a rectangular shape inside the fixed plate 506, with the end of the fixed cylinder 510 near the suction cup 511 being open.

[0028] Specifically, the outer shell of the new energy vehicle charging pile to be tested is placed in a suitable position, ensuring that its interface position is aligned with the insertion tube 504. Then, the insertion tube 504 is inserted into the interior of the interface, and the four suction cups 511 are in contact with the charging pile shell. At the same time, the rubber sealing ring 509 abuts against the edge of the charging pile shell to form a good seal. Then, the vacuum pump 507 is started through the control panel 6. The vacuum pump 507 extracts the air from the four suction cups 511 through the second movable hose and the fixed cylinder 510 to form a vacuum. Under the action of vacuum, the suction cups 511 are tightly adsorbed on the surface of the charging pile shell, further enhancing the sealing performance between the insertion tube 504 and the interface, ensuring that no gas leakage occurs during the test.

[0029] It should be noted that by adjusting the opening of the solenoid valve 502 through the control panel 6, the gas flow and pressure rise rate are controlled. When the gas pressure inside the charging pile casing reaches the preset test pressure value, the solenoid valve 502 is closed through the control panel 6 to stop the gas supply and maintain the gas pressure inside the charging pile casing stable. After maintaining the gas pressure inside the charging pile casing stable for a period of time, the pressure value sensed by the pressure sensor 505 on the control panel 6 is observed. If the pressure value remains stable, it indicates that the sealing performance of the charging pile casing is good. If the pressure value gradually decreases, it indicates that there is an air leakage in the charging pile casing, which does not meet the sealing requirements.

[0030] The working principle of the above embodiments is as follows:

[0031] During use, place the charging pile casing of the new energy vehicle to be tested in a suitable position, ensuring that its interface is aligned with the insertion tube 504. Then, insert the insertion tube 504 into the interface, with the four suction cups 511 in contact with the charging pile casing, and the rubber sealing ring 509 abutting against the edge of the charging pile casing to form a good seal. Then, start the vacuum pump 507 through the control panel 6. The vacuum pump 507 extracts the air from the four suction cups 511 through the second movable hose and the fixed cylinder 510, creating a vacuum. Under the action of vacuum, the suction cups 511 are tightly adhered to the surface of the charging pile casing, further enhancing the sealing performance between the insertion tube 504 and the interface, ensuring that no gas leakage occurs during the test. Then, turn on the air pump 3, which outputs air through the fixed tube 501 and the electric... The solenoid valve 502, the first movable hose 503, and the insertion tube 504 deliver air into the interior of the charging pile casing, increasing the air pressure inside the casing. During the air pressure test, the opening of the solenoid valve 502 is adjusted via the control panel 6 to control the gas flow and pressure rise rate. When the air pressure inside the charging pile casing reaches the preset test pressure value, the solenoid valve 502 is closed via the control panel 6 to stop the gas delivery and maintain stable air pressure inside the charging pile casing. After maintaining stable air pressure for a period of time, the pressure value sensed by the pressure sensor 505 on the control panel 6 is observed. If the pressure value remains stable, it indicates that the sealing performance of the charging pile casing is good. If the pressure value gradually decreases, it indicates that there is air leakage in the charging pile casing, which does not meet the sealing requirements.
