Description

Technical Field

[0001] This utility model relates to the field of charging detection technology, and in particular to a testing device for new energy vehicle charging systems. Background Technology

[0002] With the global energy structure transformation and the rapid development of the new energy vehicle industry, the construction scale of charging infrastructure continues to expand. The safe operation and performance stability of charging piles have become key links to ensure the healthy development of the new energy vehicle industry. To ensure that the core parameters of charging pile output voltage, current, insulation performance and other parameters meet national standards and to avoid safety accidents caused by equipment failure, it is necessary to conduct comprehensive testing of charging piles regularly using professional testing equipment. In the charging pile testing operation, the core operation is to connect the charging gun to the interface of the testing equipment to realize the conduction of the testing circuit. The charging interface of the testing equipment is located on the upper surface of the equipment. The only connection point between the charging gun and the testing equipment is concentrated at the interface position, and the snap angle between the two is fixed by the interface structure, so that the positional relationship between the wire and the interface is relatively fixed. In this connection state, the pulling force of the wire will be concentrated on the interface of the testing equipment, forming a continuous lateral load. Long-term exposure to this kind of lateral force will lead to accelerated wear of the metal contacts inside the interface, aging and deformation of the insulation sealing structure, and in severe cases, even problems such as loosening of the interface and poor contact.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a testing device for a new energy vehicle charging system. The testing device includes a main component 1, including a housing 11. An interface 12 is provided on the upper end of the housing 11, and a socket 13 is provided on the housing 11. Heat dissipation holes 14 are provided on the housing 11. During testing, the charging gun of the charging system needs to be inserted into the interface 12. The holes on the interface correspond to the sockets of the charging gun, thus fixing the position of the inserted charging gun. Therefore, the position of the wires near the charging gun is also relatively fixed. The socket 13 is used to connect the external power supply to the testing device. A display screen is also provided on the housing 11 to observe the real-time data of the test. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] Auxiliary component 2, located on housing 11, includes support member 21, which provides support and is connected to housing 11. Support member 21 includes a fixing block 211 fixed to housing 11. Lifting block 212 is slidably disposed inside fixing block 211. Through holes are opened on lifting block 212 and fixing block 211, and pins 213 are inserted into the through holes. Lifting block 212 has multiple through holes. In the initial state, the bottom of lifting block 212 is in contact with the inner bottom wall of fixing block 211. At this time, the uppermost through hole of lifting block 212 is aligned with the through hole of fixing block 211, and pins 213 are inserted into it to lock the relative position of lifting block 212 and fixing block 211. At this time, the top of fixing block 211 is lower than the upper end face of housing 11 and is in a retracted state.

[0031] When testing is required, before inserting the charging gun, move the lifting block 212 upward so that it protrudes from the upper end face of the housing 11. After it moves to the appropriate position, align the lifting block 212 with the through hole of the fixing block 211, and then insert the pin 213 to lock the position of the lifting block 212.

[0032] The auxiliary component 2 also includes an auxiliary component 22 located on top of the lifting block 212. The auxiliary component 22 is used to provide stable support for the wires near the charging gun, effectively dispersing the lateral force originally concentrated at the interface 12 to the auxiliary support system, which significantly reduces the stress load at the interface 12.

[0033] The auxiliary component 22 includes a rotating shaft 221 connected to the top of the lifting block 212 by a bearing. A rotating plate 222 is fixed on the rotating shaft 221. The top of the lifting block 212 is L-shaped. A rotating groove corresponding to the rotating plate 222 is opened on the lifting block 212. An auxiliary plate 223 is fixed on one side of the rotating plate 222. In the initial state, the auxiliary plate 223 is in a vertical state and close to the side end face of the housing 11 for easy storage. When it is necessary to provide auxiliary support for the wire, the auxiliary plate 223 will rotate to a horizontal position and lock, thereby providing stable support for the wire and preventing the force from being concentrated on the interface 12.

[0034] A gear 224 is fixed on the rotating shaft 221, and a toothed plate 225 is fixed on the fixed block 211. The gear 224 can mesh with the toothed plate 225. In the initial state, the lifting block 212 is in the lowest position, and the rotating shaft 221 and the gear 224 are also in the lowest position. The gear 224 will mesh with the toothed block at the bottom of the toothed plate 225. As the lifting block 212 moves upward, the gear 224 will also move upward. Thus, under the action of the gear 224 and the toothed plate 225, the gear 224 will rotate 90 degrees, which will drive the rotating shaft 221 and the auxiliary plate 223 to rotate 90 degrees, and finally make the auxiliary plate 223 rotate to a horizontal state.

[0035] A baffle is also fixed on the lifting block 212. The baffle is located on one side of the gear 224 to prevent the charging gun wire from contacting the gear 224 and affecting the rotation of the gear 224.

[0036] Example 2 Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the auxiliary component 2 also includes a locking member 23 disposed on one side of the gear 224. The locking member 23 is used to lock the auxiliary plate 223 in a horizontal state. The locking member 23 includes a rectangular block 231 fixed on the lifting block 212. A locking block 232 is slidably disposed inside the rectangular block 231. Several friction blocks are fixed on the locking block 232. The friction blocks are used to increase the friction between the locking block 232 and the inner wall of the rectangular block 231. Without a large external force, the locking block 232 will not slide inside the rectangular block 231. A cylinder 233 is fixed on the locking block 232. A groove corresponding to the cylinder 233 is opened on the rectangular block 231. The cylinder 233 slides in the groove, which can drive the locking block 232 to slide inside the rectangular block 231.

[0038] The size of the locking block 232 corresponds to the tooth gap size of the gear 224. When the locking block 232 moves toward the gear 224, the locking block 232 is inserted into the tooth gap. Even if the tooth plate 225 does not mesh with the gear 224 at this time, the locking block 232 prevents the gear 224 from rotating again. When the locking block 232 moves away from the gear 224, the gear 224 can rotate freely.

[0039] Specifically, an upper inclined plate 234 and a lower inclined plate 235 are fixed on the toothed plate 225. The two are located at the upper end of the toothed plate 225, and the cylinder 233 can contact the two respectively. When the lifting block 212 is in the lowest position, the locking block 232 is located in the position furthest away from the gear 224. The locking block 232 is away from the tooth block gap, and the cylinder 233 will be located in the position furthest away from the gear 224. Then the lifting block 212 moves up, and the gear 224 will rotate under the action of the toothed plate 225.

[0040] During this process, the cylinder 233 moves upward synchronously and first contacts the inclined surface of the upper inclined plate 234. It then moves upward along the inclined surface of the upper inclined plate 234. The cylinder 233 will gradually approach the gear 224, causing the locking block 232 to gradually insert into the gap between the gear blocks. As the gear 224 moves upward and separates from the gear plate 225, the locking block 232 will be fully inserted into the gap between the gear blocks, thus preventing the gear 224 from rotating and locking the auxiliary plate 223 in a horizontal state.

[0041] When the lifting block 212 moves downward, the cylinder 233 will also move downward, first contacting the inclined surface of the lower inclined plate 235, and moving downward along the inclined surface of the lower inclined plate 235. The cylinder 233 will gradually move away from the gear 224, causing the locking block 232 to completely separate from the gap between the gear block and the tooth block, unlocking the rotation restriction of the gear 224. At the same time, the gear 224 moves downward and will mesh with the tooth plate 225 again. With the cooperation of the two, the gear 224 rotates in the opposite direction, causing the auxiliary plate 223 to rotate in the opposite direction and return to the vertical state.

[0042] Specifically, the upper inclined plate 234 and the lower inclined plate 235 are connected by a connecting plate 236, which is located on one side of the upper inclined plate 234 and the lower inclined plate 235 and will not obstruct the movement of the cylinder 233.

[0043] Specifically, a lifting rod 214 is fixed on the lifting block 212, which allows the user to apply an upward pulling force to the lifting block 212.

[0044] Example 3 Reference Figure 2 , Figure 3 as well as Figure 8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the auxiliary component 2 also includes a limiting member 24 located on the auxiliary plate 223, which is used to prevent the wire from swaying laterally on the auxiliary plate 223.

[0046] The limiting member 24 includes a limiting plate 241 located on one side of the auxiliary plate 223. A fixed shaft 242 is inserted into the limiting plate 241. Support blocks 243 are connected to both ends of the fixed shaft 242 by bearings. A torsion spring 244 is sleeved on the fixed shaft 242. The two ends of the torsion spring 244 are fixed to the support block 243 and the limiting plate 241 respectively. The setting of the torsion spring 244 enables the limiting plate 241 to remain perpendicular to the auxiliary plate 223 without other external forces.

[0047] Specifically, several rubber pads 245 are fixed on the auxiliary plate 223, and a compression plate 246 is fixed on the rubber pads 245. The rubber pads 245 are deformable. When the wire is placed on the compression plate 246, downward pressure will be applied to the compression plate 246, causing the rubber pads 245 to be squeezed. The compression plate 246 can move downward a certain distance.

[0048] Specifically, a follower block 247 is fixed at the bottom of the extrusion plate 246. The lower end of the follower block 247 has two inclined surfaces. When the extrusion plate 246 moves downward, it will drive the follower block 247 to move downward synchronously. The auxiliary plate 223 has a groove corresponding to the follower block 247. The follower block 247 can only move up and down in the groove.

[0049] Specifically, a push block 248 is slidably disposed inside the auxiliary plate 223. One end of the push block 248 is inclined. A force plate 249 is fixed on the limiting plate 241. The push block 248 can contact the force plate 249.

[0050] The wire has not yet been placed on the extrusion plate 246, the rubber pad 245 is in the initial state, the follower block 247 is in the highest position, its bottom inclined surface is in contact with the inclined surface of the push block 248, and under the action of the torsion spring 244, the force plate 249 and the limiting plate 241 will be perpendicular to the auxiliary plate 223, and the force plate 249 will be in contact with the other end face of the push block 248.

[0051] When the wire is placed on the extrusion plate 246, the rubber pad 245 is compressed. The extrusion plate 246 drives the follower block 247 to move downward. Its inclined surface will apply a pushing force to the inclined surface of the push block 248, causing the push block 248 to move towards the force plate 249. This pushes the force plate 249 and causes the limiting plate 241 to rotate. The limiting plate 241 will rotate towards the center of the auxiliary plate 223, applying a pushing force to the wire in the middle and reducing the space where the wire can move. This prevents the wire from shaking in the auxiliary plate 223 during the testing process, ensuring that the wire is always in a stable supporting state and making the force dispersion effect continuous and reliable.

[0052] When removing the wire, lift the wire upwards, the rubber pad 245 returns to its original position, the squeezing plate 246 moves upwards, the pushing block 248 no longer applies a pushing force to the force plate 249, and then under the action of the torsion spring 244, the limiting plate 241 returns to its original position, so as not to obstruct the removal of the wire.

[0053] Specifically, there are two of each of the limiting plate 241, the pushing block 248, and the force plate 249. The wire is simultaneously restricted by the two limiting plates 241. The simultaneous rotation of the two limiting plates 241 will have a centering effect on the wire, ensuring the stability of the lifting.

[0054] When in use, before inserting the charging gun, remove the pin 213, hold the lifting rod 214 and move the lifting block 212 upward. When it moves to the appropriate position, align the lifting block 212 with the through hole of the fixing block 211, and then insert the pin 213 to lock the position of the lifting block 212.

[0055] As the lifting block 212 moves upward, the gear 224 also moves upward. Under the action of the gear 224, the gear 224 will rotate 90 degrees, which will drive the rotating shaft 221 and the auxiliary plate 223 to rotate, so that the auxiliary plate 223 rotates to a horizontal state. During this process, the cylinder 233 moves upward synchronously and first contacts the inclined surface of the upper inclined plate 234, and moves upward along the inclined surface of the upper inclined plate 234. The cylinder 233 will gradually approach the gear 224, which will drive the locking block 232 to gradually insert into the gap between the gear blocks. At the same time as the gear 224 moves upward and separates from the gear plate 225, the locking block 232 will be fully inserted into the gap between the gear blocks, which will prevent the gear 224 from rotating here, thereby locking the auxiliary plate 223 in a horizontal state and maintaining this state to continue moving upward.

[0056] Then, the charging gun is inserted into the interface 12, and the charging gun wire is placed on the extrusion plate 246. The rubber pad 245 is compressed, and the extrusion plate 246 drives the follower block 247 to move down. Its inclined surface will apply a pushing force to the inclined surface of the push block 248, causing the push block 248 to move towards the force plate 249. This pushes the force plate 249 and causes the limiting plate 241 to rotate. The limiting plate 241 will rotate towards the center of the auxiliary plate 223, applying a pushing force to the wire in the middle and reducing the space where the wire can move. This prevents the wire from shaking in the auxiliary plate 223 during the testing process, ensuring that the wire is always in a stable supporting state. This makes the force dispersion effect continuous and reliable, effectively dispersing the lateral force originally concentrated at the interface 12 to the auxiliary support system and reducing the stress load at the interface 12.

[0057] After the test is completed, lift the wire upwards, the rubber pad 245 resets, the squeezing plate 246 moves upwards, the pushing block 248 no longer applies force to the force plate 249, and then under the action of the torsion spring 244, the limiting plate 241 resets, which will not hinder the removal of the wire. Then, pull out the pin 213, control the lifting block 212 to slowly descend, and the cylinder 233 will also move downwards, first contacting the inclined surface of the lower inclined plate 235, and moving downwards along the inclined surface of the lower inclined plate 235. The cylinder 233 will gradually move away from the gear 224, and drive the locking block 232 to completely separate from the gap between the gear block, unlocking the rotation restriction of the gear 224. At the same time, the gear 224 moves downwards and will mesh with the gear plate 225 again. With the cooperation of the two, the gear 224 rotates in the opposite direction, causing the auxiliary plate 223 to rotate in the opposite direction and return to the vertical state, reducing the footprint and facilitating the storage of the testing device.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
