Different charging piles can provide standard charging and high-speed charging according to their internal technical indicators. Electricity is operated through the interactive terminal on the device. When the new energy charging pile placed in the basement encounters moisture, water droplets will appear around the charging head, increasing the risk of charging the charging head when it is connected to the new energy vehicle interface for charging.

[0019] like Figures 1 to 8 As shown, the moisture-proof new energy vehicle charging pile of the present invention includes: an outer shell 1, a host module 2 is configured in the outer shell 1, the host module 2 is configured with a charging head 3 through a cable, and a clamping portion 21 for placing the charging head 3 is formed on the host module 2; a dehumidification component, the dehumidification component is configured on the host module 2 and is placed around the clamping portion 21, the dehumidification component can collect part of the heat emitted by the host module 2 and conduct the part of the heat to the side around the clamping portion 21 to slowly release heat, so as to remove water vapor attached to the charging head 3.

[0020] See also Figures 1 to 4The host module 2 is used to convert AC power into DC power, thereby providing a stable charging power source for the electric vehicle. The host module 2 is a mature technology. The host module 2 is connected to the charging head 3 through a cable, and the charging head 3 is adapted to the charging socket of the electric vehicle; see Figure 1 A window is provided on one side surface of the outer shell 1, the host module 2 is arranged in the outer shell 1, and the part of the host module 2 having one side of the clamping portion 21 is relatively arranged in the window, the clamping portion 21 is adapted to the charging head 3, and the clamping portion 21 can form a clamping connection with the charging head 3, which is convenient for taking and placing the charging head 3. The clamping method of the charging head 3 and the clamping portion 21 can be a structure such as a clamping slot, a clamping block or a spring slot.

[0021] See also Figures 2 to 4 The dehumidification component is arranged on the outer circumference of the clamping part 21 of the host module 2. When the host module 2 is working, it will emit a certain amount of heat. The dehumidification component conducts the heat emitted by the host module 2 to the outer circumference of the clamping part 21 of the host module 2, thereby heating the charging head 3 placed at the clamping part 21, thereby reducing the possibility of water vapor or water droplets appearing at the charging head 3, and ensuring the safety of users when using the charging head 3 to charge new energy vehicles.

[0022] In one or more embodiments, the dehumidification component includes a clamping ring seat 41 arranged on the side of the clamping portion 21, an annular tube 42 arranged in the clamping ring seat 41 and attached to the clamping portion 21, an extension tube 43 with both ends connected to the annular tube 42, and phase change paraffin arranged in the annular tube 42 and the extension tube 43, wherein the tube body portion of the extension tube 43 extends into the outer shell 1 and is coiled on the surface of the host module 2.

[0023] See also Figure 4 The snap ring seat 41 is in a circular ring structure. The snap ring seat 41 surrounds the side of the clamping portion 21. An accommodating gap is formed between the snap ring seat 41 and the clamping portion 21. The annular tube 42 is arranged in the accommodating gap. The extension tube 43 has an inlet end and an outlet end. The inlet end and the outlet end of the extension tube 43 both pass through the snap ring seat 41 and are connected to the annular tube 42. The extension tube 43 and the annular tube 42 are both heat-conducting. The tube body of the extension tube 43 passes through the outer shell 1 and is coiled on the back surface of the host module 2. In the initial state, the annular tube 42 and the extension tube 43 are both filled with phase change paraffin powder.

[0024] When the charging pile is installed in the basement and there is moisture, there will be large fog drops around the charging head 3 of the charging pile. When the charging head 3 is plugged into the charging socket of the new energy vehicle, there may be certain safety hazards; or, when the charging pile is installed outdoors, after rainy weather, there may also be certain water drops around the charging head 3, affecting the normal use of the charging head 3; In order to solve the above technical problems, the present application adopts a dehumidification component to heat the charging head 3 clamped on the clamping part 21 of the host module 2, thereby eliminating water vapor and ensuring the normal use of the charging head 3. The specific implementation of the dehumidification component is as follows: In the initial state, the phase-change paraffin in the extension tube 43 and the annular tube 42 is in powder form. When the phase-change paraffin is heated, the powdered phase-change paraffin will be transformed into liquid phase-change paraffin. When the phase-change paraffin is no longer heated, the liquid phase-change paraffin begins to slowly release heat and gradually transforms from liquid to solid. It should be noted that the temperature at which the solid phase-change paraffin is transformed into the liquid phase-change paraffin is determined according to the type of phase-change paraffin. Generally, the type that undergoes phase change at about 35°C can be selected, and the specific selection is made according to actual production needs. When the host module 2 is working, the solid phase-change paraffin in the extension tube 43 and the annular tube 42 absorbs heat and turns into liquid phase-change paraffin. At this time, the liquid phase-change paraffin stores heat. When water vapor or moisture reappears at the charging head 3, the temperature at the charging head 3 is generally lower than 35°C. At this time, the liquid phase-change paraffin in the annular tube 42 will slowly emit heat to heat the charging head 3 at the clamping part 21 and eliminate the water vapor at the end of the charging head 3. At this time, the state of the phase-change paraffin in the annular tube 42 is changed to coexistence of solid and liquid. At the same time, the liquid phase-change paraffin inside the extension tube 43 coiled on the back of the host module 2 can be exchanged with the solid-liquid coexisting phase-change paraffin in the annular tube 42, further extending the time for the phase-change paraffin in the annular tube 42 to heat the surrounding side of the charging head 3, thereby ensuring that the charging head 3 clamped in the clamping part 21 can always remain dry.

[0025] In one or more embodiments, the annular tube 42 and the extension tube 43 are made of one of PVC, TPE, PE, and PP materials. Through this arrangement, the annular tube 42 and the extension tube 43 can have a heat-conducting function while having a certain elasticity, so that the annular tube 42 and the extension tube 43 can undergo elastic deformation, and then the liquid or solid-liquid coexisting phase-change paraffin in the extension tube 43 and the annular tube 42 can circulate and creep in the extension tube 43 and the annular tube 42, ensuring heat exchange between the liquid phase-change paraffin and the solid phase-change paraffin or the solid-liquid coexisting phase-change paraffin.

[0026] In one or more embodiments, an elastic support member 5 is disposed inside the extension tube 43 and / or the annular tube 42, and a pressing structure is disposed on the outer surface of the extension tube 43 and / or the annular tube 42; the elastic support member 5 includes a spindle portion 51 and a straight body portion 52 that are connected to each other, wherein the spindle portion 51 contacts the inner wall of the extension tube 43 and / or the annular tube 42 to prop open the extension tube 43 or the annular tube 42; the pressing structure includes a rubber airbag 6 disposed on the outer surface of the extension tube 43 and / or the annular tube 42, and a pump body for supplying air to the rubber airbag 6 or discharging the gas inside the rubber airbag 6.

[0027] See also Figure 5 , Figure 6 , Figure 7 The pump body can inflate or exhaust the rubber airbag 6 so that the rubber airbag 6 can expand and press against the extension tube 43 or the extension tube 43, or exhaust the rubber airbag 6 so that the pressed extension tube 43 or the annular tube 42 can be reset. By intermittently controlling the operation of the pump body, the rubber airbag 6 can intermittently press the extension tube 43 or the annular tube 42, so that the liquid phase-change paraffin or the phase-change paraffin in the solid-liquid coexistence state in the extension tube 43 or the annular tube 42 can creep, further improving the heat exchange capacity between the solid phase-change paraffin and the liquid phase-change paraffin, so that the liquid phase-change paraffin in the coiled extension tube 43 can exchange positions with the phase-change paraffin on the outer peripheral side of the annular tube 42, thereby ensuring the heating of the charging head 3 in this application and ensuring that the charging head 3 is always in a dry state.

[0028] See also Figure 5 , Figure 6 The elastic support member 5 is a special-shaped spring, including a spindle portion 51 and a straight portion 52. The spindle portion 51 and the straight portion 52 are connected to each other. The spindle portion 51 is a spindle-shaped structure, and the straight portion 52 is a linear structure. The spindle portion 51 can contact the inner wall of the extension tube 43 or the annular tube 42, thereby forming a support for the extension tube 43 or the annular tube 42, so as to facilitate rapid reset after being pressed by the rubber airbag 6. At the same time, when the rubber airbag 6 presses the extension tube 43 or the annular tube 42, the elastic support member 5 will pull or contract, so that the solid phase-change paraffin in the annular tube 42 or the extension tube 43 is pulled by the elastic support member 5, forming a plurality of small blocks of solid phase-change paraffin, further improving the heat exchange efficiency between the solid phase-change paraffin and the liquid phase-change paraffin.

[0029] In one or more embodiments, the rubber airbag 6 is located on the surface of the extension tube 43 and / or the annular tube 42 relative to the straight portion 52 of the elastic support member 5 .

[0030] See also Figure 5 , Figure 6 , Figure 7By making the rubber airbag 6 correspond to the straight part 52 of the elastic support member 5, the deformation degree of the rubber airbag 6 on the extension tube 43 and the annular tube 42 can be expanded, and the efficiency of the creeping of the phase-change paraffin in the liquid or solid-liquid coexisting state in the annular tube 42 and the extension tube 43 can be improved, thereby ensuring that there is always liquid phase-change paraffin in the annular member, and keeping the charging head 3 clamped on the clamping part 21 in a dry state at all times.

[0031] In one or more embodiments, the charging pile also includes an adsorption component arranged on the inner wall of the outer shell 1, and the adsorption component is used to absorb water vapor formed on the inner wall of the outer shell 1; the adsorption component includes a water-absorbing foam 71 arranged on the inner wall of the outer shell 1, a pressure plate 72 connected to the end of the water-absorbing foam 71, and a driving structure for controlling the downward movement of the pressure plate 72 to squeeze the water-absorbing foam 71; an elastic metal wire is arranged in the water-absorbing foam 71.

[0032] See also Figure 1 , Figure 2 , Figure 8 The water-absorbing foam 71 is divided into several sections in the height direction. A pressing plate 72 is fixed to the top of each water-absorbing foam 71, and the bottom of each water-absorbing foam 71 is fixed to the inner wall of the outer shell 1. An ear with a threaded hole is formed on each pressing plate 72; the driving structure is a driving motor 73 arranged on the top of the outer shell 1, and a screw 74 connected to the rotating shaft end of the driving motor 73, and the screw 74 extends into the threaded hole of the ear of the pressing plate 72. The screw 74 is controlled to rotate by the driving motor 73, and then the pressing plate 72 drives the top of the water-absorbing foam 71 to move downward, so as to squeeze the water-absorbing foam 71, so as to facilitate the discharge of the liquid absorbed by the water-absorbing foam 71, so as to further ensure that the water-absorbing foam 71 absorbs the water vapor in the outer shell 1, ensure the drying of the host module 2 in the outer shell 1, and extend the service life of the host module 2.

[0033] It should be noted that an elastic metal wire is disposed inside the water-absorbing foam 71 to ensure that the water-absorbing foam 71 can be quickly reset after being squeezed, thereby increasing the service life of the water-absorbing foam 71 .
