Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment

[0028] Given by Figures 1-4 is a cable protection device for new energy vehicle charging piles, including a new energy vehicle charging pile body 1;

[0029] A protection box body 2 is assembled and arranged on the new energy vehicle charging pile body 1;

[0030] The protection box body 2 is in a rectangular box structure and a winding cavity is formed therein;

[0031] Two positioning components 5 are assembled and arranged in the protection box body 2, and a moisture-proof component 6 is arranged between the two positioning components 5;

[0032] Among them, both of the two positioning components 5 include positioning plates 51 arranged on the inner wall of the protection box body 2. A positioning shaft 52 is installed on the side of the positioning plate 51, a sleeve 53 is slidably arranged outside the positioning shaft 52, and a clamping plate 55 is installed on the side of the sleeve 53;

[0033] Both of the two clamping plates 55 are arranged in a U shape, and the moisture-proof component 6 includes a moisture-proof box 61 clamped between the two clamping plates 55;

[0034] The moisture-proof box 61 is in a rectangular box structure and is filled with a non-woven pad cloth 62, a montmorillonite slab 63 and an activated carbon particle layer 64;

[0035] An intake fan 7 is assembled and arranged on the top of the protection box body 2.

[0036] In this embodiment, through the installation of the two positioning components 5 for the moisture-proof component 6, and through the two clamping plates 55 arranged by elastic clamping, the set moisture-proof component 6 can be quickly disassembled and assembled between the two clamping plates 55 during actual use, so as to realize quick disassembly and replacement in the protection box body 2. Considering that the non-woven pad cloth 62, the montmorillonite slab 63 and the activated carbon particle layer 64 arranged in the moisture-proof component 6 are all consumable materials, through the quick disassembly and assembly of the moisture-proof component 6, the installation of the moisture-proof component 6 in the protection box body 2 can be quickly removed, so as to facilitate the maintenance of the moisture-proof component 6.

[0037] Furthermore, during actual use, the non-woven pad cloth 62, the montmorillonite slab 63 and the activated carbon particle layer 64 arranged in the moisture-proof component 6 all have good moisture absorption performance, so as to be able to absorb the moisture in the protection box body 2, thereby reducing the influence of the humid environment on the inside of the protection box body 2, and effectively preventing the corrosion and rust of the charging cable body 4 inside the protection box body 2 by moisture; and a relatively dry environment during the use of the charging cable body 4 can be maintained. The intake fan 7 arranged on the protection box body 2 can promote the flow of air, thereby helping to discharge the humid air and further reducing the accumulation of moisture on the surface of the charging cable body 4.

[0038] Specifically, referring to Figure 4 , the non-woven pad cloth 62 is laid on the inner bottom wall of the moisture-proof box 61, the montmorillonite slab 63 is filled above the non-woven pad cloth 62, and the activated carbon particle layer 64 is filled above the montmorillonite slab 63.

[0039] In this embodiment, during use, the non-woven mat 62, montmorillonite plate 63 and activated carbon particle layer 64 have good moisture absorption properties, so they can absorb moisture in the protective box 2, thereby reducing the impact of the humid environment on the inside of the protective box 2, thereby effectively preventing moisture from corroding and rusting the charging cable body 4 inside the protective box 2; and can maintain a relatively dry environment for the charging cable body 4 during use.

[0040] Furthermore, since the non-woven mat 62, montmorillonite board 63 and activated carbon particle layer 64 will be worn out during use, the user needs to replace the non-woven mat 62, montmorillonite board 63 and activated carbon particle layer 64 in time after using them for a period of time, so as to ensure stable moisture adsorption of the protective box 2, thereby stabilizing the cable storage environment in the protective box 2.

[0041] Specifically, refer to Figure 2 and Figure 4 The moisture-proof box 61 has an opening on its upper end surface and a partition 65 is embedded therein. The partition 65 has a plurality of holes therethrough.

[0042] In this embodiment, the partition 65 is used to isolate the activated carbon particle layer 64, so as to prevent the activated carbon particle layer 64 from falling during use. At the same time, under preferred use, the partition 65 can expose the cavity inside the moisture-proof box 61, so as to facilitate moisture to enter the moisture-proof box 61 from the partition 65, so as to facilitate the non-woven pad 62, montmorillonite board 63 and activated carbon particle layer 64 to adsorb moisture.

[0043] Specifically, refer to Figure 4 A compression spring 54 is also sleeved on the outside of the positioning shaft 52 and the sleeve 53 . One end of the compression spring 54 is connected to the positioning plate 51 , and the other end thereof is connected to the clamping plate 55 .

[0044] In this embodiment, during use, the user places the moisture-proof component 6 between the two groups of positioning components 5. At this time, the moisture-proof box 61 opens the two clamping plates 55, so that the sleeve 53 can move to the outside of the positioning shaft 52. At this time, the clamping plate 55 set can compress the compression spring 54. When the clamping plate 55 is placed as a whole, the two clamping plates 55 can be driven to clamp towards each other through the reset rebound of the compression spring 54.

[0045] Specifically, refer to Figures 1-3 A winding assembly 3 is also provided in the protective box 2. The winding assembly 3 includes two rotating shaft seats 31 arranged on the inner wall of the protective box 2. Bearings are assembled in the two rotating shaft seats 31. A rotating shaft 32 is rotatably arranged between the two bearings. A winding drum 33 is sleeved on the outside of the rotating shaft 32. A charging cable body 4 is wound around the outside of the winding drum 33.

[0046] In this embodiment, during actual use, when the user needs to wind and store the charging cable body 4, by winding it around the winding cylinder 33, at this time, the bearing member provided on the rotating shaft seat 31 can ensure the stability of the rotating shaft 32 during rotation, so as to facilitate the release or retraction of the charging cable body 4 outside the winding cylinder 33.

[0047] Specifically, referring to Figures 1-3 , a box cover plate 21 is fitted and provided on the front end face of the protection box body 2, and the two are kept in sealed connection. An outlet hole 22 is opened on the back of the protection box body 2, and the diameter of the outlet hole 22 is adapted to that of the charging cable body 4.

[0048] In this embodiment, during actual use, an opening is formed on the front end face of the provided protection box body 2, so as to facilitate the user to install the winding assembly 3, the charging cable body 4, the positioning assembly 5 and the moisture-proof assembly 6 in the protection box body 2. The provided box cover plate 21 is fitted at the opening on the front end face of the protection box body 2. At the same time, the box cover plate 21 can cooperate with a waterproof gasket or other sealing materials to ensure the sealing and limiting of the protection box body 2, so as to prevent moisture from entering the protection box body 2 from the box cover plate 21. At the same time, the provided box cover plate 21 can be disassembled, so that the opening of the protection box body 2 is exposed, so as to facilitate the maintenance and overhaul of the winding assembly 3, the positioning assembly 5 and the moisture-proof assembly 6 inside the protection box body 2.

[0049] The cable protection device for a new energy vehicle charging pile of the present utility model:

[0050] The first step: During actual use, when the user needs to wind and store the charging cable body 4, by winding it around the winding cylinder 33, and then passing its end through the outlet hole 22, the new energy vehicle charging pile body 1 can be used.

[0051] The second step: When the user needs to protect the charging cable body 4, by sequentially filling the non-woven fabric 62, the montmorillonite slab 63 and the activated carbon particle layer 64 into the moisture-proof box 61, after the filling is completed, the partition plate 65 can be installed on the moisture-proof box 61, so as to isolate the activated carbon particle layer 64 and prevent the activated carbon particle layer 64 from detaching from the moisture-proof box 61.

[0052] The third step: After the moisture-proof assembly 6 is integrally installed, the moisture-proof assembly 6 can be placed between the two positioning assemblies 5. At this time, by the moisture-proof box 61 pushing open the two clamping plates 55, the sleeve 53 can move outward relative to the positioning shaft 52. At this time, the provided clamping plates 55 can compress the compression spring 54. When the clamping plates 55 are integrally placed, at this time, through the reset and rebound of the compression spring 54, the two clamping plates 55 can be driven to clamp towards each other, so as to complete the overall clamping of the moisture-proof assembly 6 by the two clamping plates 55.

[0053] Step 4: In actual use, the non-woven backing cloth 62, montmorillonite slab 63, and activated carbon particle layer 64 that are provided all have good moisture absorption performance, so as to be able to absorb the moisture in the protection box body 2, thereby reducing the influence of the humid environment on the interior of the protection box body 2, and thus effectively preventing the corrosion and rust of the charging cable body 4 inside the protection box body 2 by moisture; and can keep the charging cable body 4 in a relatively dry environment during use.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
