[0025] like Figures 1 to 4 As shown, a waterproof charging gun comprises a charging gun body 1, the charging gun body 1 comprises a plug, a gripping portion and a wire end, a fixing ring 2 is fixedly installed on the surface of the charging gun body 1 near the plug at one end, a tail ring 3 is fixedly installed on the surface of the charging gun body 1 near the wire end, a movable ring 4 is movably mounted on the surface of the charging gun body 1, a rubber sleeve 5 is fixedly connected between the opposite surfaces of the movable ring 4 and the tail ring 3, a sponge sleeve 6 is fixedly installed on the surface of the movable ring 4 near the fixing ring 2, the sponge sleeve 6 is arranged in contact with the surface of the charging gun body 1, a heating component 7 and a dehumidification mechanism 8 for drying the sponge sleeve 6 are arranged on the surface of the fixing ring 2, an installation box 9 is fixedly installed on the outer side of the movable ring 4, an elastic clamping mechanism 10 and a sliding extrusion mechanism 11 for toggling the elastic clamping mechanism 10 are arranged on the surface of the installation box 9, a spring 12 is fixedly connected between the sliding extrusion mechanism 11 and the installation box 9, a perforated block 13 is fixedly installed on the outer side of the fixing ring 2, the elastic clamping mechanism 10 penetrates the perforated block 13 and is engaged with the surface of the fixing ring 2.

[0026] More specifically, when the car owner needs to charge, the sliding extrusion mechanism 11 is squeezed relative to the mounting box 9, so that the spring 12 is compressed and the sliding extrusion mechanism 11 moves. The moved sliding extrusion mechanism 11 pushes the elastic clamping mechanism 10 to tilt up, and the elastic clamping mechanism 10 can be separated from the fixed ring 2 and the perforated block 13, and then the movable ring 4 can be moved in the direction close to the tail ring 3, so that the gripping part of the charging gun body 1 surrounded by the rubber sleeve 5 for waterproof protection is exposed, and the gripping part is in a dry state at this time. After use, the movable ring 4 is moved in the direction close to the fixed ring 2. During the movement, the sponge cover 6 fixedly installed on the surface of the movable ring 4 is used to wipe the gripping part of the charging gun body 1. The sponge cover 6 absorbs a small amount of moisture. When the movable ring 4 is in contact with the surface of the fixed ring 2, the elastic clamping mechanism 10 is clamped with the fixed ring 2, and the heating component 7 is turned on to heat and dry the sponge cover 6. The steam generated during the drying process is discharged through the dehumidification mechanism 8, so that the gripping part of the charging gun body 1 can remain dry even in rainy days outdoors, which increases the comfort of use, improves the user experience, and avoids the situation where the gripping part of the charging gun body 1 is wet and slippery due to rain and is inconvenient to use.

[0027] The heating assembly 7 includes a heating chamber 701, which is opened inside the fixing ring 2, and a heating ring 702 is fixedly installed on the inner wall surface of the heating chamber 701. Specifically, the heating chamber 701 is used to accommodate the heating ring 702, and the heat generated by the heating ring 702 after being powered on is used to dry and heat the sponge cover 6.

[0028] The moisture removal mechanism 8 includes a sponge groove 801, which is opened on one side surface of the fixing ring 2 close to the sponge sleeve 6. An air hole 802 is opened on the inner wall side of the sponge groove 801, and a rubber waterproof pad 803 is fixedly installed on the inner wall surface of the air hole 802.

[0029] Specifically, when the movable ring 4 fits with the surface of the fixed ring 2, the sponge cover 6 enters the sponge groove 801, and the heating ring 702 heats and dries the sponge cover 6. The generated water vapor is discharged through the air hole 802. The rubber waterproof pad 803 prevents a large amount of external rainwater from entering the air hole 802. At the same time, an air gap is provided for the water vapor to pass through, ensuring that the water vapor can be discharged smoothly.

[0030] There are a plurality of air holes 802 which are evenly distributed in a circular array on the side wall of the fixing ring 2 , and the specifications of the sponge sleeve 6 are adapted to the specifications of the sponge groove 801 .

[0031] Specifically, water vapor can be discharged evenly and quickly through the evenly distributed air holes 802, and the specification setting of the sponge groove 801 ensures that after the movable ring 4 fits the fixed ring 2, the sponge cover 6 can be received in the sponge groove 801, which is convenient for drying and heating the heating ring 702 on the one hand, and can absorb rainwater entering through the fitting gap between the fixed ring 2 and the movable ring 4 on the other hand, to prevent the grip from getting wet.

[0032] The elastic clamping mechanism 10 includes a rotating shaft 101, which is rotatably installed on the front and rear side walls of the installation box 9. A mounting plate 102 is fixedly mounted on the surface of the rotating shaft 101. There are two mounting plates 102 and they are arranged in front and back. A clamping rod 103 is fixedly mounted on the top surface of the mounting plate 102. A torsion spring 104 is movably mounted on the surface of the rotating shaft 101. The torsion spring 104 is arranged between the two mounting plates 102 and contacts the bottom surface of the clamping rod 103 and the outer side surface of the movable ring 4. The clamping rod 103 passes through the perforated block 13 and is clamped with the side surface of the fixed ring 2.

[0033] Specifically, by utilizing the elasticity of the torsion spring 104, the clamping rod 103 is tilted relative to the movable ring 4 in a natural state, thereby engaging with the surfaces of the fixed ring 2 and the perforated block 13. When the sliding and squeezing mechanism 11 pushes the clamping rod 103 up, the torsion spring 104 is deformed and the clamping rod 103 rotates to a horizontal state, thereby leaving the surface of the fixed ring 2 and smoothly leaving the perforated block 13, so that the movable ring 4 can leave the fixed ring 2 and move toward the direction close to the tail ring 3.

[0034] The sliding extrusion mechanism 11 includes a slide groove 111, which is opened on the front and rear sides of the inner wall of the installation box 9. A sliding plate 112 is slidably installed on the inner wall surface of the slide groove 111, a mounting block 113 is fixedly installed on the bottom surface of the sliding plate 112, a mounting shaft 114 is rotatably installed on the bottom surface of the mounting block 113, and an extrusion wheel 115 is fixedly sleeved on the surface of the mounting shaft 114. The spring 12 is fixedly installed between the mounting block 113 and the right side wall of the installation box 9, and the extrusion wheel 115 is used to drive the card rod 103 to rotate and tilt.

[0035] Specifically, pinch the mounting block 113 and the right side wall of the mounting box 9 to move the mounting block 113 toward the right side wall of the mounting box 9, so that the spring 12 is compressed and the sliding plate 112 slides in the sliding groove 111 to ensure that the mounting block 113 moves smoothly. As the mounting block 113 moves to the right, the extrusion wheel 115 at its lower end gradually contacts and squeezes the surface of the card rod 103, tilting the card rod 103 so that the card rod 103 becomes horizontal. At this time, the card rod 103 is detached from the surface of the fixing ring 2 and can leave the perforated block 13.

[0036] In summary: the elastic clamping mechanism 10 and the fixed ring 2 are engaged, so that the movable ring 4 is fixed to the surface of the fixed ring 2, so that the rubber sleeve 5 fixedly connected between the movable ring 4 and the tail ring 3 provides waterproof protection for the gripping part of the charging gun body 1, and the elastic clamping mechanism 10 can be moved by pinching the sliding extrusion mechanism 11, so that the elastic clamping mechanism 10 is no longer engaged with the fixed ring 2. At this time, the movable ring 4 can be moved toward the direction close to the tail ring 3, so that the gripping part protected by the rubber sleeve 5 in a dry state is exposed, so that the gripping part of the charging gun body 1 can remain dry even in rainy outdoor conditions, thereby increasing the comfort of use, improving the user experience, and avoiding the situation where the gripping part of the charging gun body 1 becomes slippery and inconvenient to use due to rain.
