[0051] Refer to Figure 1 , a charging pile 100 shown in an embodiment of this application, includes a base assembly 10 and a power taking assembly 20.

[0052] Please continue to refer to Figures 6 to 8, the base assembly 10 includes a bottom shell 11, a protective box 12, and a first electrical connector 13. The protective box 12 is disposed within the bottom shell 11, and the first electrical connector 13 is installed in the cavity of the protective box 12.

[0053] Optionally, both the bottom shell 11 and the protective box 12 are designed as rectangular structures, which are simple in structure and easy to manufacture and form. Of course, in other alternative embodiments, the bottom shell 11 and the protective box 12 can also adopt other shaped structures.

[0054] The materials of the bottom shell 11 and the protective box 12 can be one of plastic, metal, etc., or a combination of at least two or more.

[0055] Please continue to refer to Figure 2 , further, the bottom wall of the bottom shell 11 is provided with a mounting hole 116 for wall-mounted installation of the charging pile 100. The wall-mounted installation of the charging pile 100 can save floor space, and at the same time, the installation height can be controlled to adapt to the user's height, making it more convenient for the user to operate and use, and improving the experience.

[0056] Optionally, mounting holes 116 are provided at the four top corners or the four side edges of the bottom wall of the bottom shell 11. By passing threaded components such as bolts and expansion screws through the mounting holes 116 and installing them into the preset holes on the wall, the charging pile 100 can be installed and fixed.

[0057] Of course, in order to achieve wall-mounted installation, it is also possible to adopt the method of setting a hook on the back of the bottom shell 11 and hooking the hook to a hanging bracket on the wall, etc., and it can be flexibly selected according to actual needs.

[0058] Alternatively, as an alternative to the above wall-mounted installation, in another alternative embodiment, the charging pile 100 further includes a mounting bracket, and the mounting bracket is connected to the bottom shell 11 to enable the charging pile 100 to be floor-mounted.

[0059] Through the mounting bracket, the floor-mounted installation of the charging pile 100 can be achieved, which can improve the stability of the installation of the charging pile 100. At the same time, there is no need to drill holes in the wall, ensuring the beauty of the wall surface, and it can be applied to use occasions where there are no hanging objects such as walls and columns in the installation environment.

[0060] Please continue to refer to Figures 3 to 5 , the power-taking assembly 20 includes a housing 21, a first seal 22, a second seal 23, and a second electrical connector 24. The first seal 22 and the second seal 23 are both disposed on the side surface of the housing 21 facing the base assembly 10, and the first seal 22 surrounds the outer periphery of the second seal 23, and the second seal 23 surrounds the outer periphery of the second electrical connector 24. The second electrical connector 24 is installed on the housing 21.

[0061] When the power-taking component 20 is assembled with the base component 10, the first seal 22 is in sealing contact with the bottom shell 11 to construct a peripheral sealing structure, the second seal 23 is in sealing contact with the protection box 12 to construct an inner sealing structure, and the second electrical connector 24 is electrically connected to the first electrical connector 13.

[0062] When the charging pile 100 of the above solution is installed and used, first, the user can install and fix the base component 10 on the wall or on the ground, and then align and assemble the power-taking component 20 to the base component 10. On the one hand, during the installation process of the power-taking component 20 and the base component 10, the second electrical connector 24 is synchronously connected to the first electrical connector 13 and electrically conducted, eliminating the need for the user to perform wiring operations in a narrow space, greatly reducing the installation operation difficulty, and helping to improve the user experience. On the other hand, when the power-taking component 20 and the base component 10 are installed, the first seal 22 is in sealing contact with the bottom shell 11 to construct a peripheral sealing structure, and at the same time, the second seal 23 is in sealing contact with the protection box 12 to construct an inner sealing structure. The first electrical connector 13 and the second electrical connector 24 are enclosed inside the inner sealing structure and the inner side of the peripheral sealing structure, so that they can be protected by two inner and outer sealing structures in sequence, greatly improving the sealing and protection performance of the charging pile 100 and making it well applicable to outdoor harsh environments.

[0063] It is easy to understand that the first seal 22 and the second seal 23 are annularly closed sealing members. For example, the first seal 22 and the second seal 23 can be, but are not limited to, any one of an O-ring (rubber material), foam, etc., and can be flexibly selected according to actual needs.

[0064] In addition, in an optional embodiment, one of the first electrical connector 13 and the second electrical connector 24 is provided with a male plug terminal, and the other of the first electrical connector 13 and the second electrical connector 24 is provided with a female plug terminal, and the male plug terminal and the female plug terminal are detachably plugged.

[0065] Therefore, when the power-taking component 20 is assembled with the base component 10, the male plug terminal is directly inserted into the female plug terminal by itself, and the electrical connection between the power-taking component 20 and the base component 10 can be realized. The installation method is simple, without complex wiring operations, meeting the needs of users for simple self-installation and improving the experience.

[0066] It is easy to understand that both the female plug terminal and the male plug terminal are made of conductive materials such as metal. The female plug terminal is formed with a socket, and the male plug terminal is inserted into the socket to contact and conduct electricity with the female plug terminal.

[0067] Optionally, to ensure reliable electrical connection, multiple male plug terminals installed on the housing 21 are provided and arranged side by side at intervals; correspondingly, the female plug terminal is provided with a plurality of sockets, and the sockets are inserted into the male plug terminals one by one.

[0068] In one embodiment of the present application, the bottom case 11 has a first opening 111 and a first accommodation cavity 112 that communicate with each other. Specifically, when the bottom case 11 is a rectangular box structure, the first opening 111 is specifically an opening formed by one of the sides of the bottom case 11 with the largest surface area.

[0069] The first accommodation cavity 112 is used to accommodate the protection box 12 and the first electrical connector 13.

[0070] The protection box 12 is configured as a surrounding plate structure protruding from the bottom wall of the first accommodation cavity 112 towards the first opening 111. Optionally, the surrounding plate structure can be integrally formed with the bottom case 11 or detachably installed. In the present application, the surrounding plate structure is integrally formed with the bottom case 11, which can not only obtain higher connection strength, but also reduce the number of parts, and reduce the manufacturing process and cost of the charging pile 100.

[0071] It is easy to understand that when the first electrical connector 13 installed in the bottom case 11 is a rectangular structure, the protection box 12 also adopts a corresponding rectangular structure.

[0072] Please continue to refer to Figures 4 to 8 , a second opening 121 and a first peripheral surface 122 are provided on one side of the protection box 12 away from the bottom wall of the first accommodation cavity 112. The first peripheral surface 122 surrounds the outer periphery of the second opening 121, and the first peripheral surface 122 is in sealing contact with the second seal 23. The second opening 121 is used for the second electrical connector 24 to connect with the first electrical connector 13. Optionally, there is a certain extrusion force acting between the first peripheral surface 122 and the second seal 23 to achieve a better sealing effect.

[0073] When the power taking assembly 20 is assembled and fixed to the base assembly 10, the first peripheral surface 122 just abuts and seals with the second seal 23, so that the inner cavity of the protection box 12 forms a closed cavity, and the second electrical connector 24 and the first electrical connector 13 are connected in the closed cavity, which can effectively block external rainwater, dust, etc., and ensure the safety and reliable connection of the first electrical connector 13 and the second electrical connector 24.

[0074] Furthermore, the charging pile 100 further includes a connecting wire cable 30 and a sealing body 40. The connecting wire cable 30 is installed on the bottom case 11. A notch groove 123 is formed on the box wall of the protection box 12. The sealing body 40 is installed in the notch groove 123. One end of the connecting wire cable 30 passes through the sealing body 40 and is electrically connected to the first electrical connector 13.

[0075] Please continue to refer to Figure 1, Figure 2 and Figure 7 In addition, the charging pile 100 further includes a wire fixer 50 , which is mounted on the bottom shell 11 , the power cable 30 is connected and fixed to the wire fixer 50 , and a plug 30 a is provided at the other end of the power cable 30 extending to the outside of the bottom shell 11 .

[0076] The wire fixer 50 is used to fix the power cable 30 on the bottom shell 11 to improve the anti-pulling capability of the power cable 30 and prevent the power cable 30 from being loosened from the first electrical connector 13 when being pulled by external force, thereby affecting the connection effect.

[0077] The plug 30 a extending out of the bottom shell 11 (ie, remaining outside the charging pile 100 ) is conveniently connected to the mains to connect the electric energy to the charging pile 100 .

[0078] For example, the plug 30a can be any one of a two-pin plug and a three-pin plug, etc., which can be selected according to actual needs. The plug 30a is plugged into the socket to access the mains electricity.

[0079] The notch groove 123 is provided for installing the sealing body 40, so that the sealing body 40 is inserted into the box wall of the protection box 12, that is, the parts where the sealing body 40 and the box wall of the protection box 12 are connected overlap each other, and the sealing body 40 covers the groove side wall of the notch groove 123, so that the volume of the sealing body 40 overlaps with the volume of the protection box 12, reducing the occupation of the sealing body 40 for the internal space of the bottom shell 11, and at the same time, the groove side wall of the notch groove 123 can clamp the sealing body 40 to achieve the installation and fixation of the sealing body 40. The connecting cable 30 passes through the sealing body 40 and is electrically connected to the first electrical connector 13. The sealing body 40 has a sealing effect on the connecting cable, eliminating potential leakage points.

[0080] Please continue reading Figure 9 For example, the sealing body 40 is provided with a through hole 41 , and the power cable 30 is passed through the through hole 41 and is in sealing contact with the hole wall of the through hole 41 .

[0081] It is easy to understand that when one end of the power cable 30 is divided into multiple wires, a plurality of through holes 41 are also provided and are installed correspondingly to the multiple wires.

[0082] Furthermore, the sealing body 40 is provided with an expansion and contraction joint 42, which is connected to the through hole 41, so that the aperture size of the through hole 41 can be adjusted. In this way, by means of the expansion or contraction ability provided by the expansion and contraction joint 42, the gap size of the expansion and contraction joint 42 can be changed, so that through holes 41 with different aperture sizes can be obtained, thereby adapting to the installation needs of the power cables 30 with different wire diameters, and improving the scope of application.

[0083] Optionally, the sealing body 40 is made of a material with excellent elasticity such as rubber.

[0084] In addition, based on any of the above embodiments, a second peripheral surface 117 is formed on the wall of the first opening 111, and the second peripheral surface 117 is in sealing abutment with the first seal 22. By tightly abutting the second peripheral surface 117 against the first seal 22, the first seal 22 is forced to deform, so as to tightly fill the assembly gap between the second peripheral surface 117 and the side surface of the housing 21, thereby achieving the effects of sealing, waterproofing and dustproofing, and improving the overall IP protection level of the charging pile 100.

[0085] Please continue to refer to Figure 3 , Figure 4 and Figure 8 , further, the side surface of the housing 21 facing the base assembly 10 is provided as an installation surface 213a, and an installation groove 213b is recessed in the installation surface 213a. The installation groove 213b is arranged close to the periphery of the installation surface 213a, and the first seal 22 is installed in the installation groove 213b. Installing the first seal 22 in the installation groove 213b helps to improve the installation and positioning accuracy of the first seal 22 and prevent it from shifting after being pressed.

[0086] In addition, by arranging the installation groove 213b close to the periphery of the installation surface 213a, the first seal 22 can be arranged close to the periphery of the installation surface. Compared with the prior art in which the first seal 22 is installed on the inner wall of the housing 21, the occupation of the internal space of the housing 21 can be saved more effectively, and thus the utilization rate of the internal space of the housing 21 can be improved.

[0087] Furthermore, the second peripheral surface 117 is in sealing abutment with the first seal 22, and at the same time, the second peripheral surface 117 is in sealing abutment with the wall of the notch of the installation groove 213b; or, the second peripheral surface 117 is in sealing abutment with the first seal 22, and at the same time, the second peripheral surface 117 extends into the installation groove 213b and is in sealing abutment with the side wall of the installation groove 213b.

[0088] By means of the sealing abutment between the second peripheral surface 117 and the wall of the notch or the side wall of the installation groove 213b, another physical sealing structure can be formed on the basis of the first seal 22, strengthening the sealing reliability.

[0089] Please continue to refer to Figure 4 , in actual use, more usage scenarios of the charging pile 100 are in outdoor places, so it often encounters weather such as rain and snow. When rainwater enters the charging pile 100, it will cause the electrical components to short-circuit, and in severe cases, it will cause irreversible damage to the charging pile 100. Therefore, based on any of the above embodiments, a water retaining edge 213c is further provided on the installation surface 213a. The water retaining edge 213c protrudes towards the base assembly 10, and the water retaining edge 213c is located above the installation groove 213b and the second peripheral surface 117.

[0090] The water retaining edge 213c blocks the vertically falling rainwater, preventing the rainwater from flowing into the installation groove 213b and then leaking into the charging pile 100. At the same time, it avoids the rainwater contacting the first seal 22, preventing the first seal 22 from corroding and aging, which affects its service life and sealing effect.

[0091] Please continue to refer to Figure 4 , further, the outer wall of the bottom shell 11 is provided with a first arc-shaped recess 113, and the first arc-shaped recess 113 is arranged close to the second circumferential surface 117 and is located below the water retaining edge 213c. The provided first arc-shaped recess 113 forms an anti-backflow slope, effectively blocking the rainwater dripping on the outer wall of the bottom shell 11 from flowing back into the installation groove 213b.

[0092] Furthermore, the outer wall of the bottom shell 11 is also provided with a second arc-shaped recess 114. The second arc-shaped recess 114 is located outside the water retaining edge 213c, and the second arc-shaped recess 114 is arranged farther away from the second circumferential surface 117 than the first arc-shaped recess 113. The provided second arc-shaped recess 114 can guide the rainwater dripping on the outer wall of the bottom shell 11 to flow away from the installation groove 213b, achieving a better effect of preventing rainwater from flowing back.

[0093] In this application, refer to Figures 4 to 6 , the power taking component 20 adopts a modular design with excellent sealing performance. That is, in one embodiment, the housing 21 includes a face shell 211, a third seal 212, and an upper shell 213. The face shell 211 is hermetically assembled with the upper shell 213 through the third seal 212, so that a sealed cavity is formed between the face shell 211 and the upper shell 213. A functional module 60 and a second electrical connector 24 are installed in the sealed cavity.

[0094] After being arranged like this, the third seal 212 provides effective installation sealing for the face shell 211 and the upper shell 213, enabling a sealed cavity to be formed between the face shell 211 and the upper shell 213. The functional module 60 and the second electrical connector 24 are installed in the sealed cavity to provide reliable sealing protection for the functional module 60 and the second electrical connector 24.

[0095] It is easy to understand that the face shell 211 and the upper shell 213 can be an integral structure (i.e., non-detachable), or they can also be detachably assembled.

[0096] When the face shell 211 and the upper shell 213 are detachably assembled, it is convenient to disassemble and repair the damaged functional module 60 or the second electrical connector 24 inside. Specifically, the installation method of the face shell 211 and the upper shell 213 can be any one or more of threaded connection, snap connection, magnetic attraction connection, bonding, etc., which can be flexibly selected according to actual needs.

[0097] Optionally, the third seal 212 may be, but is not limited to, any one of an O-ring, foam, etc.

[0098] Specifically, the functional module 60 may include a power module, a control module, a communication module, and so on.

[0099] Please continue to refer to Figures 6 to 8 In this application, the upper shell 213 is disposed between the front shell 211 and the bottom shell 11. The upper shell 213 is provided with a protruding hole 213d. The second seal 23 is disposed around the outer periphery of the protruding hole 213d. The connection end of the second electrical connector 24 passes through the protruding hole 213d to be electrically connected to the first electrical connector 13.

[0100] Both the first seal 22 and the second seal 23 are installed on the mounting surface 213a of the upper shell 213 facing the base assembly 10.

[0101] Therefore, when the power-taking component 20 is assembled with the base component 10, the connection end passing through the protruding hole 213d can be connected to the first electrical connector 13 to realize the electrical connection between the second electrical connector 24 and the first electrical connector 13. At the same time, the first seal 22 and the second seal 23 disposed on the mounting surface 213a of the upper shell 213 can directly seal and abut against the bottom shell 11 and the protection box 12 to form two inner and outer sealing structures.

[0102] In one embodiment, the upper shell 213 is provided with a first assembly portion 213e, and the bottom shell 11 is provided with a second assembly portion 115. The first assembly portion 213e and the second assembly portion 115 are assembled to fix the base component 10 and the power-taking component 20.

[0103] For example, the first assembly portion 213e and the second assembly portion 115 can adopt one of the connection methods such as threaded connection, snap connection, magnetic attraction connection, etc.

[0104] Specifically in this application, the first assembly portion 213e is set as a through hole, and the second assembly portion 115 is set as a threaded hole. After the upper shell 213 and the bottom shell 11 are assembled, the through hole is exactly aligned with the threaded hole. By passing a screw through the through hole and screwing it into the threaded hole, the upper shell 213 and the bottom shell 11 can be screwed and fixed, that is, the power-taking component 20 and the base component 10 are assembled into one body. The threaded connection method is convenient and labor-saving to operate, has strong feasibility, and is beneficial to improving the user experience.

[0105] In addition to the above, this application also provides a charging device, which includes a charging execution terminal and the charging pile 100 described in any of the above embodiments. The charging execution terminal is electrically connected to the power-taking component 20 of the charging pile 100.

[0106] For example, the charging execution terminal adopts a charging gun. When in use, connecting the charging gun to the charging seat of the electric vehicle can charge the electric vehicle through the charging pile 100.

[0107] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

However, it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
