[0027] The fixing assembly includes a connecting rod 111, a fixing plate 112, a first limiting telescopic member 113, an unlocking telescopic member 115, and a third limiting telescopic member 116.

[0029] The detection assembly includes an electric slide rail 121, an electric slider 122, a pressure sensor 123, and a detection socket 124. The bottom compartment 1 is fixedly connected to the electric slide rail 121. The electric slide rail 122 is slidably connected to the electric slide rail 121. The pressure sensor 123 is fixedly connected to the electric slider 122. The detection socket 124 is fixedly connected to the electric slider 122, and the detection socket 124 is electrically connected to the pressure sensor 123. Both the detection socket 124 and the pressure sensor 123 are communicatively connected to the control console.

[0030] The simulation components include an inlet box 201, a storage tank 202, an outlet pipe 2021, a connecting pipe 203, a liquid pump 204, a test box 205, a return pipe 206, a diversion pipe 2061, and an outlet pipe 207. The liquid storage chamber 3 has several openings, each opening of which is fixedly connected to an inlet box 201, and the bottom of the inlet box 201 has a flow outlet. The bottom chamber 1 and the liquid storage chamber 3 are jointly and fixedly connected to several storage tanks 202, with the number of storage tanks 202 corresponding to the number of inlet boxes 201. Each storage tank 202 is positioned below the corresponding inlet box 201. Each storage tank 202 is equipped with a guide pipe. Each outlet pipe 2021 is equipped with a valve; all outlet pipes 2021 are connected to a connecting pipe 203; the connecting pipe 203 is fixedly connected to a liquid pump 204, and the liquid pump 204 is equipped with a conduit; the bottom compartment 1 is fixedly connected to a test box 205, and the liquid pump 204 is connected to the test box 205 through a conduit; the test box 205 is connected to a return pipe 206; the return pipe 206 is fixedly connected to several diversion pipes 2061, and the number of diversion pipes 2061 corresponds to the number of liquid storage tanks 202, and each diversion pipe 2061 is equipped with a switch valve; all liquid storage tanks 202 are connected to a liquid outlet pipe 207.

[0031] Before operation, the charging gun should be fixed to the mounting assembly, such as... Figure 5 As shown, the charging gun is placed in the middle of the fixing assembly. Then, the first limiting telescopic member 113 and the second limiting telescopic member 114 are moved toward the middle of the fixing assembly by manual or mechanical control until the first limiting telescopic member 113 fixing plate and the second limiting telescopic member 114 fixing plate contact the charging gun. This achieves the basic fixing of the charging gun, thus fixing the left and right parts of the charging gun.

[0032] In order to ensure the stability of the charging gun, the third limiting telescopic member 116 is moved towards the charging gun by manual or mechanical control until the fixing plate of the third limiting telescopic member 116 contacts the charging gun. This provides a top support for the charging gun, making the charging gun more stable during subsequent testing.

[0033] Once the charging gun is fixed in place, the first motor 101 starts working and enters the driving state, driving the connected gear 102 to rotate. The rotation of the gear 102 drives the meshing rack 103 to move to the right. The movement of the rack 103 drives the connected assembly frame 106 to move. The assembly frame 106 is connected to the sliding rail 104 through the sliding block 105, making the assembly frame 106 more stable when it moves.

[0034] The movement of the assembly frame 106 causes the connected fixed components to move until the charging gun interface aligns with the detection socket 124. At this point, the first motor 101 enters a pause operation.

[0035] At this time, the unlocking telescopic component 115 starts to work. The telescopic part of the unlocking telescopic component 115 unfolds and contacts and presses against the unlocking switch of the charging gun, so that the charging gun enters the power supply state, which facilitates subsequent testing work.

[0036] At the same time, the detection socket 124 starts working to detect the power transmission efficiency of the charging gun interface and obtain power transmission data. Simultaneously, the pressure sensor 123 starts working to detect the pressure fed back from the charging gun to the detection socket 124 and obtain normal pressure data. Through analysis by the control console, it is determined whether there is a problem with the power transmission efficiency of the charging gun under normal pressure.

[0037] However, in actual operation, charging guns encounter various special environments. Existing technical testing methods often only focus on the mechanical insertion and removal performance and electrical performance of the charging gun, while ignoring its durability under special environments.

[0038] Therefore, this device also includes a simulation component. After the pressure sensor 123 and the detection socket 124 complete the detection of the charging gun, the first motor 101 starts to work in reverse, driving the charging gun to reset and move until the charging gun moves to the preset position above the test box 205. At this time, the electric cylinder 108 starts to work, and the telescopic part of the electric cylinder 108 begins to retract. At this time, the telescopic part of the electric cylinder 108 is pulled out from the insertion hole 1121. At this time, the electric cylinder 108 releases the restriction on the fixed component. Then, the first motor 101 starts to work, driving the fixed component to rotate clockwise from a front-to-back perspective until the fixed component rotates to the position shown in the figure. Figure 7 As shown, this fixed component causes the charging gun connector to extend into the test box 205.

[0039] At this point, an acidic solution is added to the inlet box 201 manually or mechanically. The acidic solution then flows from the inlet box 201 into the storage tank 202 until the level of the acidic solution in the storage tank 202 reaches a preset height. Then, the valve on the outlet pipe 2021 opens, and the liquid pump 204 starts working, introducing the acidic solution from the storage tank 202 into the test box 205. The charging gun connector is then immersed in the acidic solution in the test box 205. Thus, under the immersion in the acidic solution, the charging gun connector simulates the effects of acid rain. After the charging gun connector has been immersed for a preset time...

[0040] The first motor 101 starts working in reverse to reset the charging gun, and then drives the charging gun to connect with the detection socket 124. In this way, the control console can detect the performance of the charging gun under acid rain simulation conditions through the detection socket 124 and the pressure sensor 123.

[0041] Furthermore, this device is additionally equipped with multiple liquid storage tanks 202 and a corresponding number of liquid inlet boxes 201. When testing the charging gun, solutions such as salt solution and simulated contamination solution can be added to the corresponding liquid storage tanks 202.

[0042] After the performance test of the charging gun under acid rain simulation is completed, the valve on the diversion pipe 2061 above the storage tank 202 containing the acidic solution is opened. At this time, the acidic solution in the test box 205 will flow back to the corresponding storage tank 202 through the return pipe 206 and the diversion pipe 2061, thus realizing the recovery of the test solution.

[0043] Furthermore, in order to further test the performance of the charging gun in other environments, test solutions such as salt solution or turbidity simulation solution are introduced into the test box 205 as needed, and then the charging gun is tested. In this way, the performance of the charging gun in different environments can be tested.

[0044] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
