With the increase of new energy vehicles, the demand for charging piles is also increasing. Most users will choose to install unique charging piles in residential areas. The current charging piles can be fixed on the ground or wall and installed in public buildings, residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. In order to ensure the safety of charging piles during use, they need to be inspected regularly.

[0003] The output power of the charging gun will change due to a variety of environmental factors.

[0033] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only intended to enable those skilled in the art to better understand and implement the subject matter described herein. In addition, the features described relative to some examples may also be combined in other examples.

[0034] like Figure 1-Figure 10 As shown, a charging pile detection device includes a multifunctional detection box 1 and a sealed environment adjustment mechanism 2 detachably connected to the multifunctional detection box 1. The multifunctional detection box 1 is used to connect the charging gun and obtain the actual output power data of the charging gun. The sealed environment adjustment mechanism 2 is used to be sleeved on the outside of the charging gun. The multifunctional detection box 1 is a prior art, which can be connected to the charging gun and has a built-in battery for storing the output power of the charging gun and obtaining the actual output power of the charging gun. Specifically, a current sensor is used to measure the current in the charging circuit; a voltage sensor is used to measure the voltage in the charging circuit, which will not be described in detail here.

[0035] The sealed environment adjustment mechanism 2 includes a splicing locking assembly 21, a splicing sleeve assembly 22 arranged in parallel with the splicing locking assembly 21, a telescopic splicing sleeve 23 connected between the splicing locking assembly 21 and the splicing sleeve assembly 22, an expansion splicing plugging assembly 24 arranged on the splicing sleeve assembly 22, and a temperature and humidity adjustment assembly 25 arranged on the splicing locking assembly 21. The multifunctional detection box 1 is provided with a fixed threaded pipe matching the splicing locking assembly 21. The expansion splicing plugging assembly 24 is used to seal the gap between the splicing sleeve assembly 22 and the charging gun. A sealed chamber is formed between the multifunctional detection box 1, the fixed threaded pipe, the splicing locking assembly 21, the telescopic splicing sleeve 23, the splicing sleeve assembly 22 and the expansion splicing plugging assembly 24, and the charging gun is located in the sealed chamber.

[0036] The temperature and humidity adjustment component 25 includes a temperature adjustment component and a humidity adjustment component, which are respectively used to adjust the temperature and humidity in the sealed chamber. The multifunctional detection box 1 is provided with a temperature and humidity sensor, which is located in the sealed chamber and is used to obtain the temperature and humidity data in the sealed chamber in real time.

[0037] It should be noted that when testing the charging pile, the following steps are specifically included:

[0038] Step S1, connecting the charging gun to the multifunctional detection box 1;

[0039] Step S2, then separate the splicing type locking assembly 21, the splicing type sleeve assembly 22, and the telescopic splicing sleeve 23 and clamp them on the charging gun, so that the separated splicing type locking assembly 21, the splicing type sleeve assembly 22, and the telescopic splicing sleeve 23 are reunited and sleeved on the charging gun;

[0040] Step S3, the splicing locking assembly 21 is brought close to the multifunctional detection box 1 and connected, the mobile splicing sleeve assembly 22 is moved to the position where the charging gun is close to the charging pile, and the expansion splicing plugging assembly 24 is expanded and bulged to seal the gap between the charging gun and the splicing sleeve assembly 22, thereby forming a sealed chamber outside the charging gun;

[0041] Step S4: Control the temperature bar adjustment component and the humidity adjustment component to adjust the temperature and humidity inside the sealed chamber, and obtain the actual output power of the charging gun during the adjustment process.

[0042] like Figure 3As shown, the spliced ​​locking assembly 21 includes two first spliced ​​semi-ring bodies 2101, a semi-annular splicing gasket 2104 fixedly connected to one end of the first spliced ​​semi-ring body 2101, a semi-annular slide groove provided on one end of the first spliced ​​semi-ring body 2101, a semi-annular splicing threaded tube 2103 slidably connected to the inner wall of the semi-annular slide groove, and a first buckle 2102 connected between the two first spliced ​​semi-ring bodies 2101. When the first buckle 2102 is in a snap-fit ​​state, the two first spliced ​​semi-ring bodies 2101 form a first ring body, and an installation groove 2105 is provided on the outer circular surface of the first spliced ​​semi-ring body 2101. The opening end of the installation groove 2105 is detachably connected with a sealing cover plate 2106.

[0043] It should be noted that, as mentioned above, after the charging gun is connected to the multi-functional detection box 1, the spliced ​​locking assembly 21 is opened, specifically, the first buckle 2102 connecting the two first spliced ​​semi-ring bodies 2101 is opened, so that the two first spliced ​​semi-ring bodies 2101 are in a separated state, and then the two first spliced ​​semi-ring bodies 2101 are respectively clamped on the outside of the charging gun and reconnected, so that the first buckle 2102 is in a connected state again. At this time, the two first spliced ​​semi-ring bodies 2101 constitute a first ring body, and the two semi-annular spliced ​​threaded tubes 2103 slidingly connected thereon form a complete threaded tube, which is threadedly connected to the fixed threaded tube on the multi-functional detection box 1, and sealed by a complete gasket formed by two semi-annular spliced ​​gaskets, so that the spliced ​​locking assembly 21 and the fixed threaded tube are sealed.

[0044] like Figure 4 As shown, the spliced ​​sleeve assembly 22 includes two second spliced ​​half rings 2201 and a second buckle 2202 connected between the two second spliced ​​half rings 2201. When the second buckle 2202 is in a snap-fit ​​state, the two second spliced ​​half rings 2201 form a second ring.

[0045] It should be noted that, as mentioned above, the working principle of the splicing locking assembly 21 is the same as that of the splicing sleeve assembly 22. When the splicing sleeve assembly 22 is sleeved on the cable of the charging gun, the second buckle 2202 between the two second splicing semi-ring bodies 2201 is first opened, so that the two second splicing semi-ring bodies 2201 are in a separated state, so that the two second splicing semi-ring bodies 2201 are clamped on the cable of the charging gun, and the second buckle 2202 is reconnected, so that the two second splicing semi-ring bodies 2201 form a complete second ring body, and the second ring body can be moved along the cable of the charging gun until it moves to a position close to the charging pile, and then the gap between the second ring body and the cable of the charging gun is sealed by the expandable splicing sealing assembly 24.

[0046] like Figure 2, Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, the telescopic splicing sleeve 23 includes a splicing telescopic pipe assembly and a splicing telescopic sealing assembly arranged inside the splicing telescopic pipe assembly, and the splicing telescopic sealing assembly is used to seal the splicing gap on the splicing telescopic pipe assembly.

[0047] The spliced ​​telescopic pipe assembly includes two first semi-ring spliced ​​telescopic tubes 2301 and a second semi-ring spliced ​​telescopic tube 2302 coaxially arranged with the first semi-ring spliced ​​telescopic tube 2301, one side end of the first semi-ring spliced ​​telescopic tube 2301 and the second semi-ring spliced ​​telescopic tube 2302 is connected with a corrugated limiting plug-in 2303, and the other side end of the first semi-ring spliced ​​telescopic tube 2301 and the second semi-ring spliced ​​telescopic tube 2302 is provided with a corrugated limiting slot 2304, the corrugated limiting plug-in 2303 is matched with the corrugated limiting slot 2304, one end of the first semi-ring spliced ​​telescopic tube 2301 and the second semi-ring spliced ​​telescopic tube 2302 is fixedly connected to the corresponding first spliced ​​semi-ring body 2101, and the other end of the first semi-ring spliced ​​telescopic tube 2301 and the second semi-ring spliced ​​telescopic tube 2302 is fixedly connected to the corresponding second spliced ​​semi-ring body 2201.

[0048] The spliced ​​telescopic sealing assembly includes two symmetrically arranged semi-annular telescopic sacs 2305, the two ends of which are fixedly connected to the corresponding first spliced ​​semi-annular body 2101 and the second spliced ​​semi-annular body 2201 respectively, a first pipe 2306 is connected to the inner wall of the mounting groove 2105, a first joint 2307 is connected to the sealing cover plate 2106, one end of the first pipe 2306 is connected to the internal space of the corresponding semi-annular telescopic sac 2305, and the other end of the first pipe 2306 is connected to the first joint 2307, and the semi-annular telescopic sac 2305 is located between the corresponding first semi-annular spliced ​​telescopic tube 2301 and the second semi-annular spliced ​​telescopic tube 2302.

[0049] It should be noted that, as mentioned above, since the first semi-ring type spliced ​​telescopic tube 2301 and the second semi-ring type spliced ​​telescopic tube 2302 are both fixedly connected between the corresponding first spliced ​​semi-ring bodies 2101 and the second spliced ​​semi-ring bodies 2201, when the two first spliced ​​semi-ring bodies 2101 and the two second spliced ​​semi-ring bodies 2201 are in a separated state, the two symmetrically arranged first semi-ring type spliced ​​telescopic tubes 2301 and the second semi-ring type spliced ​​telescopic tubes 2302 are also in a separated state, but are still in a symmetrically distributed state. When the two first spliced ​​semi-ring bodies 2101 and the two second spliced ​​semi-ring bodies 2201 are in a separated state, the two symmetrically arranged first semi-ring type spliced ​​telescopic tubes 2301 and the second semi-ring type spliced ​​telescopic tubes 2302 are in a separated state. When reconnected and sleeved on the outside of the charging gun, the two symmetrically arranged first semi-ring type spliced ​​telescopic tubes 2301 and the second semi-ring type spliced ​​telescopic tubes 2302 are also recombined to form a complete telescopic bellows. When the two first semi-ring type spliced ​​telescopic tubes 2301 and the two second semi-ring type spliced ​​telescopic tubes 2302 are spliced, the corrugated limiting plug-ins 2303 and the corrugated limiting slots 2304 arranged thereon cooperate to further improve the connection stability between the two first semi-ring type spliced ​​telescopic tubes 2301 and the two second semi-ring type spliced ​​telescopic tubes 2302 ... When the two semi-ring-type spliced ​​telescopic tubes 2302 are in a spliced ​​state, the semi-ring-type telescopic sac 2305 located between the two first semi-ring-type spliced ​​telescopic tubes 2301 and the two second semi-ring-type spliced ​​telescopic tubes 2302 can be expanded, thereby filling the space between the two first semi-ring-type spliced ​​telescopic tubes 2301 and the two second semi-ring-type spliced ​​telescopic tubes 2302, achieving a stable blocking effect, thereby achieving the effect of forming a sealed chamber outside the charging gun. When the semi-ring-type telescopic sac 2305 is expanded, specifically, it is connected to an external air pump through the first connector 2307, so as to fill the semi-ring-type telescopic sac 2305 with air. The gas causes the semi-annular telescopic sac 2305 to expand and bulge, thereby filling the space between the two first semi-annular spliced ​​telescopic tubes 2301 and the two second semi-annular spliced ​​telescopic tubes 2302, and sealing the gap between the two first semi-annular spliced ​​telescopic tubes 2301 and the two second semi-annular spliced ​​telescopic tubes 2302, so that the two first semi-annular spliced ​​telescopic tubes 2301 and the two second semi-annular spliced ​​telescopic tubes 2302 can form a double-layer complete telescopic bellows, which can effectively improve the airtightness, thereby providing a stable sealing effect for the temperature and humidity adjustment of the sealed chamber, and the air pump can be integrated into the multi-functional detection box 1.

[0050] like Figure 2 , Figure 4 and Figure 8 As shown, the expandable splicing plugging assembly 24 includes two symmetrically arranged semi-annular expansion bladders 2401 and a second joint 2402 arranged on the corresponding second splicing semi-annular body 2201, and the semi-annular expansion bladder 2401 is connected to the corresponding second joint 2402.

[0051] It should be noted that, as mentioned above, when the gap between the two second spliced ​​semi-ring bodies 2201 and the charging gun is sealed by the expandable splicing sealing assembly 24, an air pump is connected to the second joint 2402, and a set amount of gas is filled into the semi-annular expansion bladder 2401 through the air pump, so that the semi-annular expansion bladder 2401 expands and fills the gap between the second spliced ​​semi-ring body 2201 and the charging gun bracket, so that the sealed environmental adjustment mechanism 2 forms a sealed chamber outside the charging gun, thereby being able to conveniently and accurately adjust the temperature and humidity outside the charging gun.

[0052] like Figure 2 , Figure 7 As shown, the temperature regulating assembly includes an insulating electric heating layer 2501 connected between the first spliced ​​semi-ring body 2101 and the second spliced ​​semi-ring body 2201, a wire 2502 connected to the inner wall of the mounting groove 2105, and an electrical terminal 2503 connected to the sealing cover plate 2106, the two ends of the wire 2502 are electrically connected to the insulating electric heating layer 2501 and the electrical terminal 2503 respectively, and the insulating electric heating layer 2501 is arranged inside the second semi-ring spliced ​​telescopic tube 2302.

[0053] It should be noted that the power terminal 2503 is electrically connected to the multifunctional detection box 1, and the insulated electric heating layer 2501 is powered by the multifunctional detection box 1, so that the insulated electric heating layer 2501 generates heat energy. Since the insulated electric heating layer 2501 is located in a sealed chamber, the temperature in the sealed chamber can be efficiently adjusted, so that the charging gun can work in different temperature environments, thereby determining whether there is a problem with the charging gun that causes a failure in a specific temperature environment.

[0054] like Figure 2 , Figure 7 As shown, the humidity adjustment assembly includes a second pipe 2504 connected to the inner wall of the installation groove 2105 and a third joint 2505 connected to the sealing cover plate 2106, and both ends of the second pipe 2504 are connected to the sealed chamber and the third joint 2505 respectively.

[0055] It should be noted that, similarly, when adjusting the humidity in the sealed chamber, the third joint 2505 is used to connect to an external humidifier, and the humidifier can be integrated into the multifunctional detection box 1, so that water vapor is passed into the second pipe 2504 and then enters the sealed chamber, thereby adjusting the humidity inside the sealed chamber, thereby achieving the effect of accurately and efficiently adjusting the humidity in the sealed chamber.

[0056] The present embodiment is described above, but the present embodiment is not limited to the above-mentioned specific implementation manner. The above-mentioned specific implementation manner is merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, which are all within the protection of the present embodiment.
