[0034] First Embodiment

[0035] Please refer to the reference. Figures 1 to 5 This invention provides a charging pile 100 for charging new energy vehicles. It enables separate installation and wiring, improving installation efficiency, reducing labor costs, and facilitating maintenance and upkeep.

[0036] It should be noted that the charging pile 100, as a supporting facility for new energy vehicles, is generally set up in the parking lot. The charging pile 100 is fixedly installed on a fixed carrier (wall or column, etc.) in the parking lot. The fixed carrier can support and fix the charging pile 100 so that users can use the charging pile 100 to charge new energy vehicles.

[0037] The charging pile 100 includes a charging pile body 110, a mounting back plate 120, and a wiring assembly 130. The wiring assembly 130 is mounted on the mounting back plate 120, which is fixedly mounted on a fixed carrier to secure the position of the wiring assembly 130. The charging pile body 110 and the wiring assembly 130 cooperate to enable the charging pile body 110 to receive power. Specifically, the charging pile body 110 is provided with a cable 112 containing a charging gun 111. After the charging pile body 110 is powered, the user can plug the charging gun 111 into the new energy vehicle to enable the charging operation of the new energy vehicle.

[0038] The wiring assembly 130 includes an electrical connection part 131, a cover plate 133, and a limiting member 134. The electrical connection part 131 is mounted on the mounting back plate 120 and is connected to an external power source via an input line 200 to enable power to the electrical connection part 131. The charging pile body 110 is provided with a connector 113, which engages with the electrical connection part 131 to initially fix the relative position of the charging pile body 110 and the wiring assembly 130, and to enable power to the charging pile body 110.

[0039] Furthermore, there are multiple plug-in components 113 and electrical connection parts 131. Multiple plug-in components 113 are arranged in a straight line at intervals on the charging pile body 110. Each plug-in component 113 is electrically connected to one electrical connection part 131 to enable power extraction from the charging pile body 110. In this embodiment, there are five plug-in components 113 and five electrical connection parts 131 arranged side-by-side on the charging pile body 110. Each plug-in component 113 is plugged into one electrical connection part 131. However, this is not the only possibility. In other embodiments, the number of plug-in components 113 and electrical connection parts 131 can be four or six; the number of plug-in components 113 and electrical connection parts 131 is not specifically limited.

[0040] It should be noted that the cover plate 133 and the mounting back plate 120 are detachably connected and together form a receiving cavity 140 for accommodating the electrical connection part 131. The electrical connection part 131 is disposed within the receiving cavity 140. The cover plate 133 and the mounting back plate 120 work together to limit the electrical connection part 131 and prevent it from falling out of the receiving cavity 140. Furthermore, the cover plate 133 has an insertion hole 135 communicating with the receiving cavity 140. The plug-in member 113 can extend into the insertion hole 135 and enter the receiving cavity 140, and be electrically connected to the electrical connection part 131 to realize power intake of the charging pile body 110.

[0041] In this embodiment, the cover plate 133 and the mounting back plate 120 are fixed by snap-fit, but it is not limited to this. In other embodiments, the cover plate 133 and the mounting back plate 120 can also be fixed by screw connection. The method of detachable connection between the cover plate 133 and the mounting back plate 120 is not specifically limited.

[0042] In this embodiment, the mounting back plate 120 is provided with a waterproof plate 123. The waterproof plate 123 is inclinedly disposed above the cover plate 133. The waterproof plate 123 is used to stop and guide water to prevent water from flowing into the accommodating cavity 140 and improve safety.

[0043] It is worth noting that the limiting member 134 is detachably connected to the mounting back plate 120 and together they form a limiting cavity 150. The input line 200 passes through the limiting cavity 150. The limiting member 134 is used to limit the input line 200 to prevent the input line 200 from coming out of the limiting cavity 150, thus ensuring that the electrical connection part 131 is stable and reliable.

[0044] The electrical connection part 131 includes a terminal block 136 and a socket 137. The terminal block 136 is connected to the socket 137, and the connector 113 is inserted into the socket 137 and cooperates with the socket 137 to achieve electrical connection between the connector 113 and the socket 137. The terminal block 136 is used for electrical connection with the input line 200 to energize the charging pile body 110. Specifically, the socket 137 extends into the terminal block 136, and the terminal block 136 is fixed to the socket 137 by screw connection. The input line 200 extends into the terminal block 136 and is set close to the terminal block 136. The input line 200 supplies power to the socket 137 through the terminal block 136 to energize the connector 113, thereby energizing the charging pile body 110.

[0045] In this embodiment, the connector 113 is a pin. The connector 113 passes through the socket 135 and extends into the sleeve 137, and is engaged with the sleeve 137. This electrical connection method is simple and reliable, and can ensure stable current flow.

[0046] It is worth noting that the charging pile body 110 has a receiving groove 114, which is provided with a peripheral wall 115 and a bottom wall 116. The peripheral wall 115 surrounds the bottom wall 116. The mounting back plate 120 can move relative to the charging pile body 110 when the connector 113 is engaged with the electrical connection part 131, and extend into the receiving groove 114 so that the peripheral wall 115 covers the periphery of the mounting back plate 120. The peripheral wall 115 can protect and shield the mounting back plate 120 to prevent water or insects from entering.

[0047] In this embodiment, the connector 113 is disposed on the bottom wall 116, and the extension direction of the connector 113 is perpendicular to the bottom wall 116. The connector 113 can cooperate with the electrical connection part 131 in a direction perpendicular to the bottom wall 116. Specifically, during the installation of the charging pile body 110, the charging pile body 110 approaches the mounting back plate 120 in a direction perpendicular to the mounting back plate 120 so that the connector 113 can be inserted into the electrical connection part 131. During this process, the mounting back plate 120 gradually extends into the receiving groove 114. When the connector 113 and the electrical connection part 131 are fully engaged, the mounting back plate 120 is completely disposed in the receiving groove 114 and is fitted against the bottom wall 116.

[0048] It should be noted that the peripheral wall 115 has a through hole 117, and the side of the mounting back plate 120 has a mounting groove 121. The position of the through hole 117 corresponds to the position of the mounting groove 121. A nut 124 is embedded in the mounting groove 121, and the nut 124 is used to cooperate with the fixing screw passing through the through hole 117. Specifically, by embedding the nut 124 in the mounting groove 121, it is not necessary to drill a threaded hole on the side of the mounting back plate 120, which can effectively prevent water from flowing into the mounting back plate 120 through the through hole 117 and the threaded hole, thus improving safety. After the connector 113 and the electrical connection part 131 are engaged, the fixing screw is passed through the through hole 117 and tightened relative to the nut 124 to fix the relative position of the charging pile body 110 and the mounting back plate 120, thereby further fixing the relative position of the charging pile body 110 and the wiring assembly 130 and preventing the charging pile body 110 from falling off.

[0049] In this embodiment, the charging pile body 110 and the mounting back plate 120 are fixed by screw connection, but it is not limited to this. In other embodiments, the charging pile body 110 and the mounting back plate 120 can also be fixed by snap-fit. The specific limitation is not made on the way the charging pile body 110 and the mounting back plate 120 are detachably connected.

[0050] In this embodiment, there are four through holes 117, four mounting slots 121, four nuts 124, and four fixing screws. Two through holes 117 are spaced apart at the top of the peripheral wall 115, and two other through holes 117 are spaced apart at the bottom of the peripheral wall 115. Each fixing screw passes through one through hole 117 and engages with one nut 124 to improve the positioning effect. However, this is not the only embodiment. In other embodiments, the number of through holes 117, two mounting slots 121, two nuts 124, and two fixing screws can all be used, or six can all be used. The number of through holes 117, two mounting slots 121, two nuts 124, and four fixing screws is not specifically limited.

[0051] In this embodiment, a sealing strip (not shown) is provided on the side of the peripheral wall 115 near the mounting back plate 120. The sealing strip is used to seal the gap between the peripheral wall 115 and the mounting back plate 120 to further improve the waterproof and insect-proof effect, prevent water or insects from entering the charging pile body 110 through the gap between the peripheral wall 115 and the mounting back plate 120, and improve safety and reliability.

[0052] It should be noted that the mounting backplate 120 has mounting holes 122 for mounting components to pass through, so as to fix the mounting backplate 120 onto the fixed carrier. Specifically, the mounting components are mounting screws. During the installation of the mounting backplate 120, the mounting components are passed through the mounting holes 122 and tightened relative to the fixed carrier to fix the relative position of the mounting backplate 120 and the fixed carrier, preventing the mounting backplate 120 from shifting or tilting relative to the fixed carrier.

[0053] In this embodiment, there are six mounting holes 122 and six mounting components. The six mounting holes 122 are arranged in a rectangular array on the mounting back plate 120. Each mounting component passes through one mounting hole 122 and cooperates with the fixing carrier to improve the fixing effect. However, this is not the only embodiment. In other embodiments, the number of mounting holes 122 and mounting components can be four or eight. The number of mounting holes 122 and mounting components is not specifically limited.

[0054] During the installation of the charging pile 100, the mounting backplate 120 is first attached to the fixed carrier. The mounting backplate 120 is fixed to the fixed carrier by passing the mounting part through the mounting hole 122 and tightening it relative to the fixed carrier. Then, the input line 200 is inserted into the mounting backplate 120 and connected to the electrical connection part 131 installed on the mounting backplate 120. The input line 200 is limited by the limiting member 134. Next, the plug 113 of the charging pile body 110 is inserted into the electrical connection part 131, so that the mounting backplate 120 is placed in the receiving groove 114. Finally, the fixing screw is passed through the through hole 117 and tightened relative to the nut 124 to fix the relative position of the charging pile body 110 and the mounting backplate 120, thus completing the installation wiring.

[0055] The charging pile 100 provided in this embodiment of the invention includes a charging pile body 110, a mounting back plate 120 and a wiring assembly 130. The wiring assembly 130 is mounted on the mounting back plate 120. The charging pile body 110 cooperates with the wiring assembly 130 to realize the power connection of the charging pile body 110. Compared with the prior art, the charging pile 100 provided by the present invention adopts a split charging pile body 110, a mounting back plate 120, and a wiring assembly 130 mounted on the mounting back plate 120. The charging pile 100 is divided into a wiring part (mounting back plate 120 and wiring assembly 130) and a main body part (charging pile body 110). The wiring part is relatively lightweight, making it convenient to move and operate during wiring. Even if the wiring part is accidentally dropped on the ground, the entire wiring part can be replaced directly. In addition, if the smart hardware in the main body part is updated or needs to be repaired in the future, the entire main body part can be replaced or repaired separately without removing the wiring part from the wall. This provides high flexibility. In this way, split installation and wiring can be achieved, improving installation efficiency, reducing labor costs, and facilitating maintenance and upkeep.

[0056] Second Embodiment

[0057] Please refer to Figure 6 This invention provides a charging pile 100. Compared with the first embodiment, the difference in this embodiment is that the extension direction of the connector 113 is different.

[0058] In this embodiment, a clearance opening 118 is provided at the bottom of the peripheral wall 115. The clearance opening 118 communicates with the receiving groove 114 and is used to allow clearance for the mounting back plate 120. The mounting back plate 120 can extend into the receiving groove 114 through the clearance opening 118. The extension direction of the plug-in 113 is parallel to the bottom wall 116, and the plug-in 113 can cooperate with the electrical connection part 131 in a direction parallel to the bottom wall 116. Specifically, during the installation of the charging pile body 110, the charging pile body 110 approaches the mounting back plate 120 in a direction parallel to the mounting back plate 120 so that the plug-in 113 can be inserted into the electrical connection part 131. During this process, the mounting back plate 120 passes through the clearance opening 118 and gradually extends into the receiving groove 114. When the plug-in 113 and the electrical connection part 131 are fully engaged, the mounting back plate 120 is completely disposed in the receiving groove 114.

[0059] Furthermore, the connector 113 extends vertically downward and can engage with the electrical connection portion 131 in the same direction. During the installation of the charging pile body 110, the charging pile body 110 moves vertically downward against the mounting back plate 120 so that the connector 113 can be inserted into the electrical connection portion 131.

[0060] In this embodiment, the connector 113 is disposed on the bottom wall 116 and is disposed parallel to the bottom wall 116. However, it is not limited to this. In other embodiments, the connector 113 is disposed on the peripheral wall 115 and is disposed parallel to the bottom wall 116. The specific location of the connector 113 is not limited.

[0061] The beneficial effects of the charging pile 100 provided in this embodiment of the invention are the same as those in the first embodiment, and will not be repeated here.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
