[0027] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0029] This embodiment provides a power battery charging structure, which can restrict and clamp the charging gun head, making it more secure and stable when inserted into the charging structure. Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, it includes a charging part body 10, a charging port 1 adapted to the charging gun head, a limiting component 2 for limiting the charging gun, and a locking member 3 for limiting the limiting component 2. The charging part body 10 includes a charging port 1, a plurality of connecting parts 11 and two hollow cylinders 12 are provided in the charging port 1, a magnet block 13 is provided in the hollow cylinder 12, and two slideways 14 are also provided in the charging port 1. The limiting component 2 includes a sliding plate 20, and a plurality of through holes are provided on the surface of the sliding plate 20. Two connecting rods 21 are provided on the outside of 20. The connecting rods 21 are designed as a semi-cylindrical structure. The opposite surfaces of the two connecting rods 21 are provided with rubber pads 211. The surface of the connecting rod 21 is penetrated by an opening 214. The opposite surfaces of several connecting rods 21 are provided with rubber pads 211. Locking parts 3 are provided between several connecting rods 21 and the hollow cylinder 12, so that the limiting component 2 can be effectively utilized to limit the charging gun head, avoiding the accidental situation that the charging plug is easily loosened or falls off under pressure during use.

[0030] To prevent the limiting component 2 located in the charging port 1 from falling outward, Figure 2-7As shown, in this embodiment, a second slide 212 is provided through the surface of the connecting rod 21, and a threaded hole 213 connected to the second slide 212 is provided through the surface of the connecting rod 21. A bolt 4 is provided on the surface of the connecting rod 21 through the threaded hole 213, and the output end of the bolt 4 protrudes into the second slide 212. The bolt 4 and the hollow cylinder 12 are on the same horizontal plane, so that the bolt 4 protruding into the second slide 212 and the hollow cylinder 12 can be effectively utilized to limit the limit component 2, effectively preventing the limit component 2 from separating and falling off from the charging port 1.

[0031] To prevent foreign objects from accidentally falling into the charging port 1 and causing inconvenience in cleaning, Figure 3-7 As shown, in this embodiment, the locking member 3 includes a metal rod 31, one end of the metal rod 31 protrudes into the hollow cylinder 12 and is adsorbed by the magnet block 13, and a metal plate 32 is provided at the end of the metal rod 31 away from the magnet block 13, and a convex plate 33 is provided on the surface of the metal plate 32. The convex plate 33 is located in the opening 214 opened by the connecting rod 21, so that the staff can adjust the position of the limit assembly 2 in the charging port 1 after adjusting the locking member 3, thereby achieving a driving effect on the debris, which is more conducive to the staff to handle the debris that accidentally falls into the charging port 1.

[0032] To prevent the metal rod 31 from separating from the connecting rod 21 and falling off, Figure 5-7 As shown, in this embodiment, a retaining ring 215 is provided along a ring on the surface of the connecting rod 21 and near the opening 214. The metal rod 31 is designed as a cylindrical structure. A limiting ring 34 is provided along a ring on the outer side of the metal rod 31. The limiting ring 34 is located on the outside of the retaining ring 215, so that the limiting ring 34 can be effectively utilized to limit the position of the metal rod 31 to avoid separation from the connecting rod 21.

[0033] In order to make the surface of the bolt 4 connected to the connecting rod 21 more stable, as shown in FIG. Figure 3 As shown, in this embodiment, a rubber ring 5 is provided on the surface of the connecting rod 21, and the bolt 4 is in close contact with the surface of the rubber ring 5 through the threaded hole 213, so as to prevent the bolt 4 from loosening due to the shaking generated during the driving of the new energy vehicle.

[0034] In order to facilitate the staff to grasp and press the limit component 2 and adjust the position, Figure 1 and Figure 3 As shown, in this embodiment, the opposite surfaces of several connecting rods 21 are engraved with meshing lines.

[0035] When using the power battery charging unit structure, the charging gun can be first inserted into the charging unit body 10. During the insertion process, the two rubber pads 211 provided on the opposite sides of the charging gun and the connecting rod 21 are in close contact, and the rubber pads 211 are deformed, so that the charging gun head is more firmly inserted into the charging unit body 10. If foreign debris falls into the charging unit body 10 and the debris needs to be cleaned, the staff can use both hands to grab the two protruding plates 33 through the opening 214 respectively, and apply pressure and pull to the side close to each other to separate the metal rod 31 from the magnet block 13 and away from the hollow cylinder 12. Finally, the limit assembly 2 is pressed and slid toward the outside of the charging unit body 10 to make the output rod of the bolt 4 contact the surface of the hollow cylinder 12. At this time, the sliding plate 20 and the entrance of the charging port 1 are close to each other, and finally the staff can clean the debris more conveniently.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
