[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-4 The utility model provides the following technical solutions: A charging pile testing device for new energy vehicles, including a tester 1, the front end of the tester 1 is equipped with a display screen 2, an indicator light 3, a switch button 4 and a charging gun plug hole 6, a handle 5 is installed on the side wall of the tester 1, and a support plate 7 is installed at the front end of the tester 1 near the charging gun plug hole 6, a spring 8 is installed inside the support plate 7, a limit block 10 is installed on the top of the spring 8, and the top of the limit block 10 is connected to a fixed block 9.

[0025] In the preferred embodiment, the fixing block 9 and the limiting block 10 are connected as one piece, and the cross-sections of the fixing block 9 and the limiting block 10 are T-shaped.

[0026] In the preferred embodiment, the limiting block 10 is elastically and telescopically connected to the support plate 7 via the spring 8 .

[0027] In the preferred embodiment, the end of the fixing block 9 is arc-shaped, and the fixing block 9 and the limiting block 10 are telescopically connected inside the support plate 7 through the spring 8 .

[0028] In the embodiment, first, the car charging pile needs to be tested during charging, including the charging speed, the temperature generated during charging, etc., and then the charging gun socket 6 of the tester 1 needs to be docked with the charging gun on the charging pile. During the docking process, the charging gun will squeeze the fixed block 9 to shrink, and then drive the limit block 10 to squeeze the spring 8 to shrink together. After the docking is completed, the fixed block 9 rebounds due to the elastic force of the spring 8, and then drives the fixed block 9 to engage with the charging gun, which effectively reduces the situation where the charging gun and the charging gun socket 6 are separated due to looseness.

[0029] In addition, the tester 1 belongs to the existing mature technology, and its working principle also belongs to the existing mature working principle. Therefore, this article will not elaborate on how the tester 1 specifically tests the charging pile.

[0030] Example 2

[0031] See also Figure 1-4 A first supporting foot 11 is installed at the bottom of the tester 1, a placement plate 12 is provided at the back of the tester 1, a connecting block 13 is installed at the back of the tester 1, a first magnetic block 14 is installed at the back of the tester 1, and a second magnetic block 15 is installed on the inner side wall of the placement plate 12.

[0032] In the preferred embodiment, the placement plate 12 is magnetically connected to the tester 1 via the first magnetic block 14 and the second magnetic block 15 .

[0033] In the preferred embodiment, the outer side wall of the placement plate 12 is connected with a sleeve 16 , and the end of the sleeve 16 is threadedly connected with a second supporting leg 17 .

[0034] In the embodiment, the tester 1 is first firmly placed on the ground using its first support leg 11. Subsequently, the placement plate 12 is unfolded by a rotation operation. During this process, the first magnetic block 14 and the second magnetic block 15 are automatically separated to ensure that the placement plate 12 can be smoothly opened. When the placement plate 12 is longitudinally unfolded and parallel to the ground, if the height needs to be further adjusted to ensure stability, the second support leg 17 can be rotated so that it extends from the sleeve 16 until it reaches the desired height and firmly contacts the ground. In this way, a stable and spacious platform is constructed, which is convenient for placing test auxiliary equipment including various sensors on the placement plate 12, so as to perform precise testing operations.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
