Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0030] Example 1:

[0031] In this embodiment of the invention, a retractable plug for new energy vehicles with a protective structure includes a charging gun body 1, and a charging plug 4 is provided at the end of the charging gun body 1. The charging plug 4 is used to insert into the vehicle charging port to realize the charging operation.

[0032] In this embodiment of the invention, specifically, the charging gun body 1 is based on an existing charging pile and is used to realize the charging operation of new energy vehicles;

[0033] In this embodiment of the invention, a protective component is further provided between the charging gun body 1 and the charging plug 4. The protective component includes an annular protective frame 15. An annular groove 9 is opened inside the charging gun body 1. The annular protective frame 15 is slidably connected inside the annular groove 9. A plurality of support springs 1501 are fixedly installed between the annular protective frame 15 and the annular groove 9. The charging plug 4 is rotatably installed inside the annular protective frame 15. A wiring terminal 14 is fixedly installed at the center of the end of the charging plug 4, and a wire body 10 is connected inside the wiring terminal 14. A plurality of elastic support rods 16 are fixedly installed between the wiring terminal 14 and the annular protective frame 15.

[0034] In this embodiment of the invention, specifically, during the charging process, the charging gun body 1 is removed from the charging pile by hand, and then the charging plug 4 is inserted into the charging port of the vehicle to be charged.

[0035] In this embodiment of the invention, specifically, by setting up the annular protective frame 15, when the charging gun body 1 is impacted during the charging process, it can drive the charging plug 4 to rotate inside the annular protective frame 15, squeezing the multiple elastic support rods 16, so that the charging gun body 1 can tilt. When the impact force disappears, the charging gun body 1 can be reset through the cooperation of the multiple elastic support rods 16, further ensuring the protection effect of the charging gun body 1 and the charging plug 4, and avoiding damage due to impact.

[0036] In this embodiment of the invention, specifically, when the charging gun body 1 is subjected to an impact force along the charging plug 4 during the charging process, the charging gun body 1 can be moved towards the charging plug 4 under force, so that the annular protective frame 15 can lead the charging plug 4 into the annular groove 9, squeezing the multiple support springs 1501 until the impact force disappears and then resets, further improving the protective effect of the device.

[0037] In this embodiment of the invention, specifically, the ring-shaped protective frame 15 and the charging plug 4 can extend and retract inside the charging gun body 1. On the one hand, they can buffer the impact force and ensure the normal charging process of the device, thus improving the protection of the device. On the other hand, when the charging plug 4 is inserted into the charging port of the vehicle to be charged, if the insertion force is too large, the ring-shaped protective frame 15 can retract inside the charging gun body 1 until the insertion is completed and the ring-shaped protective frame 15 is reset after being released, further ensuring the protective performance of the charging gun body 1 during the insertion process.

[0038] In this embodiment of the invention, specifically, the charging gun body 1 is provided with a locking component for locking when the charging plug 4 is inserted into a preset position.

After charging is completed, as the electric push rod 13 runs, it can drive the locking tongue 1201 to move upward and cancel the lock.

[0040] In this embodiment of the invention, specifically, when the charging gun body 1 is subjected to an impact force, the annular protective frame 15 extends and retracts inside the annular groove 9. At this time, the locking plate 12 can slide inside the locking frame 11 under force until the annular protective frame 15 is reset, thus ensuring the locking effect.

[0041] In this embodiment of the invention, specifically, a rectangular groove 1101 is provided on the outer side of the locking frame 11 for the locking plate 12 to pass through when it slides inside the locking frame 11 under force;
