[0025] Thus, the pressing member 31 can switch between a first pressed position and a first released position; the reset elastic member 66 connects the pressing member 31 and the frame 1; under the action of external force, the user can press the pressing member 31 to the first pressed position; when the external force is removed, the reset elastic member 66 can restore the pressing member 31 to the first released position; the frame 1 has a cavity 11, and the external electronic lock 51 can be placed in the cavity 11; the cavity 11 has an opening 12, the sealing plate 2 covers the opening 12, and the sealing plate 2 seals the opening 12, and the sealing plate 2 can prevent moisture from entering the cavity 11 through the opening 12, so as to avoid moisture affecting the electronic lock 51 in the cavity 11; the sealing plate 2 has a first hole 21; the first pressing rod 33 is used to cooperate with the cam 512 of the electronic lock 51 in the cavity 11; One end of the first pressing rod 33 is connected to the pressing member 31. During the pressing process, the pressing member 31 can drive the first pressing rod 33 to move. The other end of the first pressing rod 33 passes through the first hole 21 and extends into the cavity 11. The first elastic seal 41 seals the gap between the first pressing rod 33 and the inner wall of the first hole 21. When the first pressing rod 33 moves, it can cooperate with the cam 512 of the electronic lock 51 (the cam 512 here refers to the cam 512 of the electronic lock 51 in the cavity 11). The first elastic seal 41 can always seal the gap between the first pressing rod 33 and the inner wall of the first hole 21, preventing moisture from seeping into the cavity 11 along the first pressing rod 33 and preventing moisture from affecting the electronic lock 51 in the cavity 11.

[0026] In one embodiment, the pressing member 31 in this application is equivalent to the mechanical lock in (Chinese Invention Patent; Publication No.: CN107591648A; Subject: Charging Plug and Charging Pile Including the Charging Plug; Publication Date: 2018-01-16). In one embodiment, the electronic lock 51 in this application is equivalent to the electronic lock in CN107591648A. In one embodiment, the first pressing rod 33 in this application is equivalent to the protrusion at the bottom of the second end in CN107591648A. In one embodiment, the cam 512 in this application is equivalent to the first cam in CN107591648A.

[0027] In one embodiment, the reset elastic element 66 is clamped between the pressing element 31 and the frame 1.

[0028] In one embodiment, a sealing ring 61 is laid along the edge of the opening 12, the sealing ring 61 extends along the edge of the opening 12, and the sealing ring 61 is clamped between the edge of the opening 12 and the sealing plate 2.

[0029] In one embodiment, the space sealing within the cavity 11 can achieve an IP67 protection rating.

[0030] In one embodiment, the user drives the pressing member 31 to rotate by pressing one end of the pressing member 31.

[0031] In one embodiment, the pressing member 31 is rotatable about the pivot 32 between a first pressed position and a first released position.

[0032] Further, please refer to Figures 1 to 17 In one specific embodiment of the waterproof structure provided by this utility model, the first elastic sealing element 41 is a first sealing ring; the first sealing ring is sleeved on the first pressing rod 33, and the first sealing ring is clamped between the first pressing rod 33 and the inner wall of the first hole 21. In this way, the annular first sealing ring is more firmly sleeved on the first pressing rod 33.

[0033] In addition, the first sealing ring with an annular cross-section structure can generate a uniformly distributed sealing contact stress when subjected to radial pressure. This means that regardless of whether there is a slight offset in the position of the first pressing rod 33 at the center of the hole, the first sealing ring can compensate for uneven contact through its own elastic deformation, maintain a 360° gapless fit in the circumference, and effectively inhibit liquid from seeping into the cavity 11 from any direction.

[0034] Further, please refer to Figures 1 to 17 As a specific embodiment of the waterproof structure provided by this utility model, it further includes: a first pressure plate 43; the edge of the first hole 21 has a first annular groove 211; a first sealing ring is filled in the first annular groove 211; the first pressure plate 43 is detachably fixed to the sealing plate 2; the first pressure plate 43 has a first mounting hole 431, and the first pressing rod 33 passes through the first mounting hole 431; the first sealing ring is sandwiched between the bottom wall of the first annular groove 211 and the first pressure plate 43. In this way, the first sealing ring can maintain its stable position when it is set in the first annular groove 211.

[0035] In addition, the first pressure plate 43, through its detachable fixation to the sealing plate 2, presses the first sealing ring tightly against the bottom wall of the first annular groove 211, thereby achieving axial preload control. The presence of the first pressure plate 43 changes the force direction of the sealing ring from a single radial compression to a composite compression of "axial and radial" forces. This makes the sealing ring less prone to undesirable deformations such as overturning, extrusion, or creep during operation, thus improving sealing stability.

[0036] In one embodiment, the first pressure plate 43 is fixed to the sealing plate 2 by a first screw.

[0037] Further, please refer to Figures 1 to 17As a specific embodiment of the waterproof structure provided by this utility model, it further includes: a second pressing rod 34, a pressing switch 67, and a second elastic seal 42; the pressing switch 67 is used for electrical connection with the electronic lock 51; the pressing switch 67 is disposed in the cavity 11; a second hole 22 is provided on the sealing plate 2; one end of the second pressing rod 34 is connected to the pressing member 31, and the other end of the second pressing rod 34 passes through the second hole 22 and extends into the cavity 11; the pressing switch 67 is located on the pressing movement path of the second pressing rod 34; the second elastic seal 42 fills and seals between the second pressing rod 34 and the inner wall of the second hole 22. Thus, a second hole 22 is provided on the sealing plate 2; one end of the second pressing rod 34 is connected to the pressing member 31, and the other end of the second pressing rod 34 passes through the second hole 22 and extends into the cavity 11. The second elastic sealing member 42 seals the gap between the second pressing rod 34 and the inner wall of the second hole 22, preventing moisture from seeping into the cavity 11 along the second pressing rod 34, and preventing moisture from affecting the electronic lock 51 in the cavity 11; the second pressing rod 34 can trigger the pressing switch 67 during the pressing and moving process.

[0038] In one embodiment, the electronic lock 51 is de-energized after the push switch 67 is triggered.

[0039] Further, please refer to Figures 1 to 17 In one specific embodiment of the waterproof structure provided by this utility model, the second elastic sealing element 42 is a second sealing ring; the second sealing ring is sleeved on the second pressing rod 34, and the second sealing ring is clamped between the inner wall of the second pressing rod 34 and the second hole 22. In this way, the annular second sealing ring is more firmly sleeved on the second pressing rod 34.

[0040] In addition, the second sealing ring with an annular cross-section structure can generate a uniformly distributed sealing contact stress when subjected to radial pressure. This means that regardless of whether there is a slight offset in the position of the second pressing rod 34 at the center of the hole, the second sealing ring can compensate for uneven contact through its own elastic deformation, maintain a 360° gapless fit in the circumference, and effectively inhibit liquid from seeping into the cavity 11 from any direction.

Thus, the second sealing ring, positioned within the second annular groove 221, can maintain its stable position.

[0042] In addition, the second pressure plate 44, through its detachable fixation to the sealing plate 2, presses the second sealing ring tightly against the bottom wall of the second annular groove 221, thereby achieving axial preload control. The presence of the second pressure plate 44 changes the force direction of the sealing ring from single radial compression to a composite compression of "axial and radial" forces. This makes the sealing ring less prone to undesirable deformations such as overturning, extrusion, or creep during operation, thus improving sealing stability.

[0043] In one embodiment, the second pressure plate 44 is fixed to the sealing plate 2 by a second screw.

[0044] Further, please refer to Figures 1 to 17 As a specific embodiment of the waterproof structure provided by this utility model, it also includes: a dust cover 35; the dust cover 35 is detachably mounted on the frame 1, and the dust cover 35 covers part of the outer side of the pressing member 31.
