Description

Technical Field

[0001] This utility model relates to the field of charging pile plug-in / plug-out simulation testing, and more specifically, to a charging pile plug-in / plug-out simulation testing device. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. The charging gun is the tool that transfers power from the charging pile to the car battery. During the production of charging guns, plugging and unplugging simulation tests can simulate the situation in real-world use where users repeatedly plug and unplug the charging gun. Through testing, the stability and reliability of the connection between the charging gun and the charging interface can be evaluated. This helps to avoid equipment damage or charging interruption caused by improper plugging and unplugging, thereby ensuring that electric vehicles can be charged normally and safely.

[0003] A search revealed that Chinese Patent Publication No. CN220437739U discloses "a charging gun insertion / removal testing device, which includes a testing platform and further comprises: a linear track fixedly connected to the top surface of the testing platform; a rotating component fixedly connected to the testing platform; an adjustment platform fixedly connected to the rotating end of the rotating component; a rotating disk installed on the top of the adjustment platform; a moving rod sliding inside the linear track, with one end of the moving rod also limited to sliding on the top surface of the rotating disk; a clamping component fixedly connected to the end of the moving rod farther from the rotating disk, and the clamping component can be adapted to clamp the charging gun; and a lifting component fixedly connected to the top surface of the testing platform, and the lifting component can be adapted to fix the charging socket. This utility model effectively avoids the low efficiency and difficulty in controlling the insertion / removal force of existing manual insertion / removal tests, which helps to save labor costs and improve the efficiency of insertion / removal tests." However, it still has the following drawbacks:

[0004] When conducting insertion and removal tests, the device is operated by manually rotating the first threaded rod, which causes the charging gun held by the clamped component to reciprocate. The insertion and removal test requires multiple insertion and removal tests. Manually rotating the first threaded rod would waste a lot of manpower and be inconvenient to use.

[0005] Therefore, we have made improvements to this by proposing a simulated plugging and unplugging test device for charging piles. Utility Model Content

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a simulated plugging and unplugging test device for charging piles, including a base plate 1, a test mechanism 2 is provided on the top of the base plate 1, and a guide component 3 is provided on one side of the test mechanism 2.

[0036] like Figure 3 and Figure 5As shown, the testing mechanism 2 includes an electric push rod 201, a support base 202, a fixing part 203, a first lead screw 204, a positioning part 205, a support frame 206, a test plate 207, and a replacement assembly 208. The electric push rod 201 is fixedly connected to one end of the top of the base plate 1. The support base 202 is fixedly connected to the telescopic end of the electric push rod 201. The fixing part 203 is fixedly connected to the side wall of the support base 202. The first lead screw 204 is threaded into the interior of the fixing part 203. The positioning part 205 is rotatably connected to one end of the first lead screw 204. The support frame 206 is disposed on one side of the support base 202. The test plate 207 is disposed on... The charging gun is placed inside the support frame 206. The top of the support base 202 has a slot for placing the charging gun. The support frame 206 is bolted to the base plate 1. There are two fixing parts 203, two first lead screws 204 and two positioning parts 205, which are located on opposite side walls of the support base 202. The two adjacent positioning parts 205 are close to each other. When in use, the charging gun is inserted into the support base 202, and then the two first lead screws 204 are rotated to make the two positioning parts 205 close to each other, thereby fixing the charging gun. Then the electric push rod 201 is activated to drive the charging gun to reciprocate, which greatly reduces manual labor.

[0037] like Figure 3 As shown, the replacement component 208 includes a rectangular plate 2081 and a simulated charging port 2082. The rectangular plate 2081 is slidably connected to the inside of the test board 207. The simulated charging port 2082 is opened on the side wall of the rectangular plate 2081. When the charging gun reciprocates, one end of the charging gun will be inserted and removed back and forth inside the simulated charging port 2082 to perform insertion and removal tests. Because the rectangular plate 2081 is bolted to the test board 207, the corresponding rectangular plate 2081 can be replaced according to the model of the charging gun.

[0038] like Figure 3 and Figure 4 As shown, the guide assembly 3 includes a rectangular groove 301, an isolation net 302, an air inlet pipe 303, and an exhaust fan 304. The rectangular groove 301 is located at the top of the base plate 1. The isolation net 302 is attached to the inner wall of the rectangular groove 301. The air inlet pipe 303 is connected to the bottom of the rectangular groove 301. The exhaust fan 304 is attached to the bottom of the base plate 1. During use, prolonged plugging and unplugging may cause wear on the surface of the charging gun, generating tiny debris. At this time, the exhaust fan 304 is activated, which guides the air above the base plate 1, thereby sucking the debris to the top of the isolation net 302 for convenient and unified disposal of the debris.

[0039] like Figure 1 As shown, two guide rails 4 are fixedly connected to the top of the base plate 1. Both guide rails 4 are slidably connected to the support base 202. When in use, the two guide rails 4 can guide the bottom of the support base 202 and improve the accuracy of the support base 202 when it moves.

[0040] like Figure 1 As shown, a second lead screw 5 is rotatably connected to the top of the test board 207, and a rotating ring 6 is fixedly connected to the top of the second lead screw 5. The top of the second lead screw 5 passes through the support frame 206 and is threadedly connected to the support frame 206. When in use, the second lead screw 5 is manually rotated, thereby raising and lowering the test board 207 and the rectangular plate 2081, so that the simulated charging port 2082 is coaxial with the charging gun.

[0041] like Figure 3 As shown, limit grooves 7 are provided on both inner side walls of the support frame 206, and limit plates 8 are fixedly connected to the opposite side walls of the test plate 207. The two limit plates 8 are slidably connected to the two limit grooves 7 respectively. When the charging gun is inserted into the simulated charging port 2082, the limit plates 8 will be restricted by the limit grooves 7 to prevent the test plate 207 from shifting.

[0042] like Figure 1 As shown, four support legs 9 are fixedly connected to the bottom of the base plate 1, and a reinforcing rod 10 is fixedly connected between two adjacent support legs 9. The four support legs 9 are located at the four corners of the base plate 1 respectively. When in use, the support legs 9 can provide support for the base plate 1 and prevent the exhaust fan 304 from contacting the ground.

[0043] like Figure 1 As shown, a stabilizing rod 11 is welded to the side wall of the support frame 206. The other end of the stabilizing rod 11 is bolted to the base plate 1. When in use, the stabilizing rod 11 can provide support for the support frame 206, prevent the support frame 206 from shaking, and ensure that the charging gun can be accurately inserted into the simulated charging port 2082.

[0044] like Figure 1 As shown, the positioning part 205 is made of polyurethane. The positioning part 205 made of polyurethane has the advantage of high wear resistance, which can prevent the surface of the clamped charging gun from being worn.

[0045] like Figure 5 As shown, a knob 12 is fixedly connected to one end of the first lead screw 204 away from the positioning part 205. An anti-slip groove 13 is provided on the outer wall of the knob 12. There are several anti-slip grooves 13, which are distributed circumferentially along the central axis of the knob 12. When in use, the first lead screw 204 can be rotated more conveniently by using the knob 12.

[0046] Specifically, when using the simulated plug-in / plug-out testing device for this charging pile: connect the electric push rod 201 and the exhaust fan 304 to an external power source, then insert the charging gun into the support base 202, then rotate the two first lead screws 204 to bring the two positioning parts 205 closer together, thereby fixing the charging gun, then rotate the second lead screw 5 to drive the test plate 207 and the rectangular plate 2081 to rise and fall, making the simulated charging port 2082 coaxial with the charging gun, then start the electric push rod 201 to drive the charging gun to reciprocate, and then one end of the charging gun will be plugged in and out of the simulated charging port 2082 to perform the plug-in / plug-out test. Prolonged plugging and unplugging may cause wear on the surface of the charging gun, producing tiny debris. At this time, start the exhaust fan 304, which will guide the air above the base plate 1, thereby sucking the debris to the top of the isolation net 302 for convenient unified disposal of the debris.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
