With the improvement of environmental awareness, new energy vehicles have been favored by more and more consumers, and the importance of charging equipment related to new energy vehicles has gradually become prominent. When charging new energy vehicles, charging guns have become indispensable equipment.

Liquid-cooled charging guns are one type of new energy vehicle charging guns, which are mainly composed of charging heads, liquid cooling devices, cooling pipes, etc. When in use, liquid-cooled charging guns cool the electronic components and batteries in the charging device through liquid circulation, thereby ensuring the normal operating temperature of the charging device and the battery, improving charging efficiency and battery life. When existing new energy vehicle charging guns are engaged outside the charging cabinet, water vapor and dust in the external environment are likely to damage the charging port.

The existing patent document with announcement number CN220374309U discloses a new energy vehicle charging gun. After charging is completed, the first hollow ring plate is reset to the left, and the multiple triangular card plates are in the fitting position again to form a whole circle, and rubber sealing strips are arranged at the joints of the multiple triangular card plates. The multiple rubber sealing strips are attached with magnetic strips to increase the sealing of the entire triangular card area, prevent external dust and water vapor from affecting the charging port, and help to ensure the service life of the charging port. Compared with the traditional method of using a connecting rope to fix the dust cover, this method of setting the dustproof mechanism connection is more practical, and the method of use is more concise and clear, which avoids the phenomenon that the dust cover is lost due to frequent breakage of the connecting rope due to its short life.

Although the above-mentioned new energy vehicle charging gun can solve the corresponding technical problems, the first hollow ring plate needs to be manually reset to the left after charging is completed to achieve the shielding and protection of the charging port. However, due to repeated manual resetting of the first hollow plate, water vapor and dust in the external environment are still likely to damage the charging port.

Referring to Figures 1-5, an embodiment of the utility model is a liquid-cooled charging device for new energy vehicles, including a liquid-cooled charging gun 1 for charging new energy vehicles, a protective component 2 for shielding and protection, and a support component 3 for supporting the protective component 2 and for automatic resetting. The protective component 2 is arranged at the charging port of the liquid-cooled charging gun 1, and the support component 3 is arranged between the liquid-cooled charging gun 1 and the protective component 2; the support component 3 includes an L-shaped frame 31 fixedly connected to the top of the liquid-cooled charging gun 1, and the bottom of the L-shaped frame 31 is movably connected with a support rod 32, one end of the support rod 32 is arranged on the protective component 2, and a slide groove 33 is provided at the bottom of the L-shaped frame 31, and the inner cavity of the slide groove 33 is slidably connected with a slider 34, one side of the slider 34 is fixedly connected with a spring 35, and the other end of the spring 35 is fixedly connected to one side of the inner wall of the slide groove 33.

Referring to Figures 1 and 2, the protective component 2 includes a folding shield 21 that is arranged at the charging port of the liquid-cooled charging gun 1. One side of the folding shield 21 is fixedly connected to the liquid-cooled charging gun 1, and the other side of the support ring 22 is fixedly connected to the support ring 22. The inner cavity of the support ring 22 is rotatably connected to a plurality of baffles 23 that are evenly distributed and used to block and block the inner cavity of the support ring 22. The baffle 23 has a fan-shaped structure, and one end of the support rod 32 away from the L-shaped frame 31 is fixedly connected to the outer surface of the support ring 22. It should be noted that the specific structure and working principle of the above-mentioned protective component 2 are consistent with the prior art, and therefore will not be repeated in this technical solution.

As shown in Figures 4 and 5, a through hole 341 is opened inside the slider 34, and a guide rod 36 is movably provided through the inner cavity of the through hole 341. Both ends of the guide rod 36 are fixedly connected to the inner wall surface of the slide groove 33. Through the setting of the guide rod 36, the slider 34 can be guided, so that the slider 34 can stably move along the axial direction of the guide rod 36; the axial directions of the guide rod 36, the support ring 22, the folding baffle 21 and the charging port of the liquid-cooled charging gun 1 are all in the same straight line; the inner ring diameter of the spring 35 is larger than the diameter of the guide rod 36, and the spring 35 is sleeved on the surface of the guide rod 36. The guide rod 36 can also limit the spring 35, so that the reverse elastic force generated by the spring 35 during compression can always be in the same straight line with the direction of the pressure, avoiding the spring 35 from being skewed, which helps to extend the service life of the spring 35.

Grooves 342 are provided at the top and bottom of the inner cavity of the through hole 341, and a ball 343 is movably embedded in the inner cavity of the groove 342. A guide groove 361 is provided on the surface of the guide rod 36 for the ball 343 to roll. When the slider 34 slides on the surface of the guide rod 36, the slider 34 can drive the ball 343 to roll in the inner cavity of the guide groove 361, which helps to reduce the friction between the inner wall of the through hole 341 and the surface of the guide rod 36, improve the flexibility of the slider 34 when moving, and avoid the phenomenon of jamming when the slider 34 moves.

A rubber pad 37 is sleeved on one end of the surface of the guide rod 36, and one side of the rubber pad 37 is glued to the inner wall surface of the slide groove 33. The setting of the rubber pad 37 plays a buffering role for the slider 34, effectively preventing the slider 34 from directly colliding with the inner wall surface of the slide groove 33 and causing damage when resetting.

When the embodiment of the utility model is used, the support ring 22 is pushed toward the direction of the L-shaped frame 31, the support ring 22 drives the support rod 32 to move, the support rod 32 drives the slider 34 to slide in the inner cavity of the slide groove 33 and the surface of the guide rod 36, the spring 35 is forced to shrink, and the slider 34 drives the groove 342 and the ball 343 to move synchronously, so that the ball 343 rolls in the inner cavity of the guide groove 361. At the same time, several baffles 23 are squeezed by the charging port of the liquid-cooled charging gun 1 and flipped open until the charging port of the liquid-cooled charging gun 1 is completely exposed, and the liquid-cooled charging gun 1 can be plugged into the new energy vehicle for charging operations.

After charging is completed, the liquid-cooled charging gun 1 is unplugged from the new energy vehicle. At this time, the support ring 22 loses its constraint, and the elastic force of the spring 35 can eventually drive the protective component 2 to move to its original position, thereby completing the shielding and protection operation of the charging port of the liquid-cooled charging gun 1.

The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
