[0052] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0053] This embodiment relates to a charging pile, which is also called a charging terminal or charging device and is used to charge electric vehicles. As Figure 1 shown, it is an exploded schematic view of the charging pile, and as Figure 2 shown, it is a structural schematic view of the assembled charging pile, and as Figure 3As shown, it is an exploded view of the panel assembly of the charging pile. Among them, in the schematic diagram of the charging pile in this embodiment, the charging gun is not schematically shown.

[0054] Refer to Figure 1 As shown, the charging pile includes a panel assembly and a rear shell 5. Refer to Figure 2 As shown, the panel assembly is fixed to the front side of the rear shell 5. Refer to Figure 3 As shown, the panel assembly includes a front cover 1, a display module 2, and a cover plate 3. The front cover 1 has a mounting opening 11 that penetrates its thickness. The display module 2 is installed in the mounting opening 11. The cover plate 3 covers the outside of the display module 2 and is fixedly connected to the front cover 1. A sealing ring surrounding the mounting opening 11 is arranged between the cover plate 3 and the front cover 1 to prevent moisture, dust, etc. in the environment from entering the chamber between the front cover 1 and the rear shell 5 through the mounting opening 11.

[0055] Since the content displayed on the display surface of the display module 2 is for users to view, the cover plate 3 has light transmissivity in the area corresponding to the display module 2, so that users can view the content displayed by the display module 2 through the cover plate 3.

[0056] In one example, the display module 2 can specifically be a digital tube. A digital tube is an electronic component used to display numbers and simple characters. It is usually composed of 7 light-emitting diode segments arranged in an "8" shape, so it is also called a 7-segment digital tube. Some also have a decimal point (the 8th segment), and this kind of digital tube is generally also called an 8-segment digital tube.

[0057] As a display module, the digital tube has a simple structure, is convenient to control, has a low cost, a long service life, and clear display and high brightness, and is more suitable for dim environments.

[0058] In one example, since the display module 2 is a digital tube rather than an electronic display screen, then, refer to Figure 2 As shown, the panel assembly can be curved, with a streamlined appearance, which better meets the aesthetic needs of modern buildings or public settings, thereby enhancing the beauty of the charging pile.

[0059] For example, refer to Figure 3 As shown, the outer surface of the front cover 1, the display surface of the display module 2, and the outer surface of the cover plate 3 included in the panel assembly are all curved surfaces.

[0060] In one example, the outer surface of the front cover 1 is a curved surface. It can be that the curvature of the inner surface and the outer surface of the front cover 1 is the same, and both are curved surfaces. The front cover 1 itself is a curved panel material. Among them, the inner surface of the front cover 1 is also the surface located inside the charging pile, that is, the surface facing away from the cover plate 3, and the outer surface of the front cover 1 is the surface facing the cover plate 3.

[0061] Similarly, refer to Figure 3As shown, the outer surface of the cover plate 3 is a curved surface. It is possible that the curvature of the inner surface and the outer surface of the cover plate 3 is the same, both being curved surfaces. Among them, the inner surface of the cover plate 3 is the surface facing the front cover 1, and the outer surface is the surface located outside the charging pile.

[0062] The digital tube is used as the display module 2 in the curved panel assembly. Compared with the electronic display screen used as the display module 2 in the curved panel assembly, the content displayed is more natural, enhancing the user's viewing effect and being beneficial to improving the aesthetics of the charging pile. This is because when the electronic display screen is used as the display module 2 in the curved panel assembly, the content displayed will be uneven in height and inconsistent in size, resulting in a poor user experience.

[0063] Of course, the digital tube can also be used as the display module 2 in the flat panel assembly. In the flat panel assembly, the outer surface of the front cover 1, the display surface of the display module 2, and the outer surface of the cover plate 3 are all flat surfaces.

[0064] As described above, the display module 2 is installed in the installation opening 11 of the front cover 1. For example, the display module 2 is fixed to the inner surface of the front cover 1 (i.e., the surface located in the chamber formed by the front cover 1 and the rear shell 5) by screws, and the display surface of the display module 2 faces the cover plate 3.

[0065] As an example, the display surface of the display module 2 is coplanar with the outer surface of the front cover 1. For example, if the display surface of the display module 2 and the outer surface of the front cover 1 are both flat surfaces, then the plane where the display surface of the display module 2 and the outer surface of the front cover are located is coplanar. Another example is that if the display surface of the display module 2 and the outer surface of the front cover 1 are both curved surfaces, then the curvature of the display surface of the display module 2 and the outer surface of the front cover 1 is the same.

[0066] As another example, the display surface of the display module 2 extends out of the installation opening of the front cover 1, then the display surface of the display module 2 is higher than the outer surface of the front cover 1.

[0067] As described above, the cover plate 3 covers the outside of the display module 2. Then, in order to enable the user to more clearly see the content displayed by the display module 2, correspondingly, the inner surface of the cover plate 3 facing the front cover 1 is attached to the display surface of the display module 2.

[0068] In one example, the cover plate 3 covers the outside of the display module 2. The area of the cover plate 3 can be equal to the area of the front cover 1, and the cover plate 3 covers the outside of the front cover 1. For example, the inner surface of the cover plate 3 facing the front cover 1 is attached to the outer surface of the front cover 1. The better the attachment degree between the cover plate 3 and the front cover 1, the smaller the gap between the two. Thus, moisture, dust, etc. in the environment where the charging pile is located are less likely to enter between the cover plate 3 and the front cover 1, and are also less likely to enter the interior of the charging pile through the installation opening 11. Among them, the interior of the charging pile, that is, the chamber formed after the front cover 1 and the rear shell 5 are buckled together, is provided with electronic components and some circuits.

[0069] In one example, the cover plate 3 can be a glass cover plate or a plastic cover plate. Since the clarity of the glass cover plate is better than that of the plastic cover plate, and moreover, the texture of the glass cover plate is better than that of the plastic cover plate, the cover plate 3 can be a glass cover plate to enhance the aesthetics of the panel of the charging pile.

[0070] In one example, the glass cover plate is directly installed on the front cover 1 by screws. The exposure of the screws will affect the aesthetics. The glass cover plate is bonded to the front cover 1 by an adhesive method, but it needs to be bonded in place at one time. However, it is difficult to install the glass cover plate in place at one time during the assembly with the front cover 1, which will result in a low yield of the panel assembly.

[0071] Therefore, as Figure 4 shown, which is another exploded view of the panel assembly, referring to Figure 4 shown, the cover plate 3 can include a glass plate 31 and a fixing plate 32. Among them, the material of the glass plate 31 is transparent glass or semi-transparent glass, and the fixing plate 32 is a plastic part for fixing the glass plate 31 on the front cover 1.

[0072] As Figure 5 shown, which is a schematic diagram after the glass plate 31 and the fixing plate 32 are fixed, Figure 5 showing the inner surface of the fixing plate 32 facing the front cover 1. Referring to Figure 5 shown, the glass plate 31 and the fixing plate 32 are adhesively fixed together. For example, the inner surface of the glass plate 31 is adhesively bonded to the outer surface of the fixing plate 32, and then, the fixing plate 32 and the front cover 1 are fixed together. For example, the fixing plate 32 and the front cover 1 are fixed together by screws.

[0073] Since the fixing plate 32 does not have light transmittance, therefore, referring to Figure 4 and Figure 5 shown, the fixing plate 32 has a first opening 321 at the position corresponding to the display module 2, and the orthographic projection of the display surface of the display module 2 on the fixing plate 32 falls within the first opening 321.

[0074] And in order to make the content displayed on the display surface of the display module 2 clearer, then, as Figure 6As shown, it is a schematic cross-sectional view of the panel assembly. Refer to Figure 6 As shown, the display surface of the display module 2 extends out of the mounting opening 11 of the front cover 1 and the first opening 321 on the fixing plate 32, and fits against the inner surface of the glass plate 31. The closer the display surface of the display module 2 is to the inner surface of the glass plate 31, the clearer the content displayed on the display surface of the display module 2 is for the user.

[0075] In one example, the panel assembly of the charging pile generally further includes a lamp. Refer to Figure 4 As shown, the lamp 6 is installed on the front cover 1. The fixing plate 32 has a second opening 322 at a position corresponding to the lamp 6. The size and shape of the second opening 322 respectively match the size and form of the lamp 6. Then, after the cover plate 3 including the glass plate 31 and the fixing plate 32 is covered and fixed on the front cover 1, the lamp 6 can still emit light beams outward through the second opening 322 of the fixing plate 32 and the glass plate 31.

[0076] As described above, the fixing plate 32 and the front cover 1 can be fixed together by screws. Then, as Figure 7 shown, it is another schematic cross-sectional view of the panel assembly. Figure 6 The cross-section in Figure 7 and the cross-section in Figure 7 are cut at different positions. Refer to Figure 7 As shown, the inner surface of the fixing plate 32 facing the front cover 1 has screw hole columns 323, and the inner surface of the front cover 1 facing away from the fixing plate 32 has through hole columns 12. Then, the inner surface of the fixing plate 32 fits against the outer surface of the front cover 1, and the screw hole columns 323 on the fixing plate 32 extend into the through hole columns 12 of the front cover 1. For the fixing screw, it is screwed into the screw hole columns 323 of the fixing plate 32 from the inner surface of the front cover 1. Refer to

[0077] Continue to refer to Figure 7 As shown, the through hole columns 12 of the front cover 1 are also the inner surface (the surface facing away from the fixing plate 32) of the front cover 1 having columns. The columns have through holes extending through the height, and the through holes also penetrate the thickness of the front cover 1. The screw hole columns 323 of the fixing plate 32 are also, refer to Figure 7 shown, the inner surface of the fixing plate 32 facing the front cover 1 also has columns. The columns have through holes extending through the height of the columns, and the through holes have threads, but the through holes do not penetrate the thickness of the fixing plate 32. In this way, the screw hole columns on the fixing plate 32 cannot be seen through the glass plate 31 on the front of the charging pile, so as to improve the aesthetics.

[0078] In one example, the number of screw hole columns 323 on the fixing plate 32 is multiple, and the number of through hole columns 12 on the front cover 1 is also multiple. The multiple through hole columns 12 on the front cover 1 correspond one-to-one with the screw hole columns 323 on the fixing plate 32. Refer to Figure 4 As shown, the front cover 1 has five through hole columns 12, four of which surround the installation opening 11, for example, are respectively located at the four vertex positions of the installation opening 11, and the other through hole column 12 is located at the bottom of the front cover 1. Refer to Figure 5 As shown, the inner surface of the fixing plate 32 has five screw hole columns 323, four of which surround the first opening 321 and are respectively located at the four vertex positions of the first opening 321, and the other screw hole column 323 is located at the bottom of the second opening 322. Then, the fixing plate 32 is fixed on the outer surface of the front cover 1 by five screws.

[0079] Of course, in this embodiment, there is no limitation on the number of screws used to fixedly connect the front cover 1 and the fixing plate 32. This embodiment also does not limit the fixed connection between the front cover 1 and the fixing plate 32 by screws. The front cover 1 and the fixing plate 32 can also be fixedly connected by gluing, or can be fixedly connected by a snap connection method.

[0080] As described above, the panel assembly can be a curved panel assembly. Then, in the solution where the cover plate 3 includes the glass plate 31 and the fixing plate 32, the glass plate 31 and the fixing plate 32 can also be curved panels, and the curvature of the glass plate 31 is the same as that of the fixing plate 32.

[0081] In one example, since the display module 2 is installed in the installation opening 11 of the front cover 1, then, water vapor, dust, etc. in the environment may enter the cavity formed by the front cover 1 and the rear shell 5 through the gap between the front cover 1 and the cover plate 3 and pass through the installation opening 11, which may affect the service life of the charging pile and even cause a short circuit of the charging pile.

[0082] Therefore, as described above, a sealing ring is arranged between the cover plate 3 and the front cover 1, and the sealing ring is in a compressed state between the cover plate 3 and the front cover 1 and surrounds the installation opening 11. In this way, even if water vapor, dust, etc. in the environment enter the gap between the cover plate 3 and the front cover 1, it is not easy to pass through the installation opening 11 and enter the interior of the charging pile under the block of the sealing ring.

[0083] In one example, refer to Figure 4 and Figure 6As shown, on the outer surface of the front cover 1 facing the cover plate 3, there is a first annular groove 13. The first annular groove 13 surrounds the mounting opening 11. Then, the sealing ring between the front cover 1 and the cover plate 3 can be embedded in the first annular groove 13. Moreover, the sealing ring 4 is also in a compressed state between the cover plate 3 and the front cover 1. For example, the fixing plate 32 of the cover plate 3 is pressed against the sealing ring 4.

[0084] In another example, the first annular groove 13 can also be provided on the inner surface of the cover plate 3 facing the front cover 1. For example, in the solution where the cover plate 3 includes a glass plate 31 and a fixing plate 32, the first annular groove 13 can be provided on the inner surface of the fixing plate 32 facing the front cover 1. The sealing ring 4 is embedded in the first annular groove. After the cover plate 3 and the front cover 1 are fixed, the front cover 1 is pressed against the sealing ring 4.

[0085] In this embodiment, it is not specifically limited whether the first annular groove is provided on the outer surface of the front cover 1 or on the inner surface of the fixing plate 32 of the cover plate 3. In the drawings, it is shown that the first annular groove is provided on the outer surface of the front cover 1.

[0086] Reference Figure 4 As shown, the first annular groove 13 for placing the sealing ring 4 has its groove opening facing the fixing plate 32 and has two relatively positioned groove walls (denoted as the first groove wall and the second groove wall respectively). The height of the first groove wall close to the mounting opening 11 is higher than that of the second groove wall. The first groove wall with a relatively high height can play a role in reference positioning during the process that the display surface of the display module 2 extends out of the mounting opening 11 and fits with the glass plate 31.

[0087] In one example, in order to compress the sealing ring 4 between the front cover 1 and the cover plate 3, correspondingly, as Figure 5 And with reference to Figure 6 As shown, on the inner surface of the cover plate 3 facing the front cover 1, there is a first annular rib 324. The first annular rib 324 extends into the first annular groove 13 of the front cover 1 to press against the sealing ring 4 within the first annular groove 13.

[0088] Reference Figure 6 As shown, in the solution where the cover plate 3 includes a glass plate 31 and a fixing plate 32, the first annular rib 324 can be provided on the inner surface of the fixing plate 32 facing the front cover 1.

[0089] As described above, the first annular groove 13 can also be provided on the fixing plate 32 of the cover plate 3. Then, in this solution, the first annular rib is provided on the outer surface of the front cover 1.

[0090] That is, in one solution, the first annular groove is provided on the outer surface of the front cover 1, and the first annular rib is provided on the inner surface of the fixing plate 32. In another solution, the first annular groove is provided on the inner surface of the fixing plate 32, and the first annular rib is provided on the outer surface of the front cover 1. In the drawings, it is shown with the first annular groove provided on the outer surface of the front cover 1 and the first annular rib provided on the inner surface of the fixing plate 32.

[0091] In one example, referring to Figure 4 as shown, the first annular groove 13 is adjacent to the mounting opening 11, arranged around the mounting opening 11, and within the area surrounded by the plurality of through-hole columns 12. In this way, the sealing ring 4 around the mounting opening 11 near the mounting opening 11 can also block water vapor, dust, etc. entering from the through-hole columns 12 outside to prevent them from entering the mounting opening 11.

[0092] In one example, in order to quickly fix the cover plate 3 on the front cover 1, correspondingly, the outer surface of the front cover 1 facing the cover plate 3 has a first positioning structure, and the inner surface of the cover plate 3 facing the front cover 1 has a second positioning structure 325. The cover plate 3 is positioned on the outer surface of the front cover 1 through the cooperation of the first positioning structure and the second positioning structure 325. Then, after the cover plate 3 and the front cover 1 are positioned, the screw holes between the cover plate 3 and the front cover 1 are also aligned, and then only need to screw the screws. Thus, it is beneficial to quickly assemble the cover plate 3 and the front cover 1.

[0093] Among them, the first positioning structure can be an annular groove, and the second positioning structure can be an annular rib. Or, the first positioning structure is an annular rib, and the second positioning structure is an annular groove.

[0094] For example, in the solution where the cover plate 3 includes a glass plate 31 and a fixing plate 32, referring to Figure 4 and Figure 6 as shown, the first positioning structure on the outer surface of the front cover 1 is an annular groove, located at the outer edge position of the front cover 1, and the second positioning structure 325 on the inner surface of the fixing plate 32 is an annular rib, located at the outer edge position of the fixing plate 32.

[0095] Furthermore, the groove wall of the annular groove has a chamfer at the groove opening position, and the end of the annular rib has a chamfer, so that the cover plate 3 can be quickly positioned on the outer surface of the front cover 1.

[0096] In one example, if the first positioning structure is an annular groove, then a sealing ring can be arranged in the first positioning structure. The second positioning structure is an annular rib, which extends into the annular groove and presses on the sealing ring in the annular groove. Then, a sealing ring is arranged at the outer edge between the cover plate 3 and the front cover 1, and a sealing ring is arranged at the mounting opening 11. The cover plate 3 and the front cover 1 are sealed by two sealing rings to achieve double-layer sealing, so that the panel assembly has good waterproof and dustproof performance.

[0097] Similarly, the first annular rib and the first annular groove near the installation opening 11 can also play a positioning role during the assembly of the cover plate and the front cover. Then, the end of the first annular rib can have a chamfer, and the groove wall of the first annular groove can also have a chamfer at the notch.

[0098] In one example, in the solution where the first positioning structure on the outer surface of the front cover 1 is an annular groove, or the second positioning structure on the inner surface of the fixing plate 32 is an annular groove, the annular groove can be used as a drainage groove to drain the water flowing into the annular groove downward. This is because the charging pile is generally erected on the ground. Then, the liquid entering between the front cover 1 and the fixing plate 32 can flow downward along the annular groove. Due to the chamfer at the notch of the groove wall of the annular groove, it can flow out of the annular groove under the action of the chamfer.

[0099] In the embodiment of the present disclosure, the panel assembly of the charging pile includes a front cover, a display module, and a cover plate. The front cover has an installation opening, and the display module is installed in the installation opening. This split design of the display module and the front cover can prevent the content displayed on the display module from being deformed even if the panel assembly is a curved panel assembly, and the displayed content is more natural, which is beneficial to improving the aesthetic feeling of the charging pile. Moreover, the front cover and the cover plate are sealed by a sealing ring, which can effectively prevent water vapor and dust in the environment from entering the interior of the charging pile through the installation opening and affecting the internal circuit. Therefore, the panel assembly provided by the embodiment of the present disclosure has good waterproof and dustproof performance.

[0100] This embodiment also provides a charging pile. Refer to Figure 1 and Figure 2 As shown, the charging pile includes a rear shell 5 and the above-mentioned panel assembly, and the front cover 1 of the panel assembly is fixedly connected to the rear shell 5.

[0101] As Figure 8 shown, it is a cross-sectional schematic diagram of the charging pile. As Figure 9 shown, it is a partial schematic diagram within area A in Figure 8 . Refer to Figure 8 and Figure 9 shown, the inner surface of the front cover 1 facing the rear shell 5 has a first annular clamping structure at the outer edge position, and the inner surface of the rear shell 5 facing the front cover 1 has a second annular clamping structure at the outer edge position. Then, the front cover 1 and the rear shell 5 can be clamped through the first annular clamping structure and the second annular clamping structure to achieve pre-positioning, and then fixed together by screws.

[0102] Refer to Figure 8As shown, both the first annular clamping structure and the second annular clamping structure are annular grooves. In another example, the first annular clamping structure is an annular groove and the second annular clamping structure is an annular rib. In another example, the first annular clamping structure is an annular rib and the second annular clamping structure is an annular groove.

[0103] Continue to refer to Figure 8 and Figure 9 As shown, at least one of the first annular clamping structure and the second annular clamping structure is an annular groove. Then, a sealing ring 4 in a compressed state can be placed in the annular groove, and this sealing ring is compressed between the front cover 1 and the rear shell 5. For the solution where both the first annular clamping structure and the second annular clamping structure are annular grooves, the sealing ring 4 can be placed in both of these two annular grooves, or the sealing ring 4 can be placed in one of these two annular grooves (refer to Figure 9 As shown, the sealing ring 4 is placed in one of the two annular grooves).

[0104] In the embodiment of the present disclosure, the panel assembly of the charging pile, as described above, includes a front cover, a display module, and a cover plate. The front cover has an installation opening, and the display module is installed in the installation opening. This split design of the display module and the front cover makes it difficult for the content displayed on the display module to be deformed even if the panel assembly is a curved panel assembly, and the displayed content is more natural, which is beneficial to improving the aesthetics of the charging pile. Moreover, the front cover and the cover plate are sealed by a sealing ring, which can effectively prevent water vapor and dust in the environment from entering the interior of the charging pile through the installation opening and affecting the internal circuit. Therefore, the panel assembly provided by the embodiment of the present disclosure has good waterproof and dustproof performance.

[0105] The above are only the preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
