DETAILED DESCRIPTION
[0035] The technical solutions in the embodiments (or “modes of implementation”) of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0037] The application provides a charging pile 100. The charging pile 100 of the application will be described in detail below in combination with the drawings. The features in the following embodiments and implementation manners can be combined with each other without conflict.
[0038] The application provides a charging pile 100, as shown in Figures 1-3 The application provides a charging pile 100, as shown in
[0039] The return detection of the charging gun is realized by the limit switch 120, which simplifies the structure of the return detection of the charging gun and reduces the manufacturing cost of the charging pile 100. When the limit switch 120 is in the first state, the electronic components of the charging pile 100 are controlled by the controller 140 to enter the standby state, which reduces the energy consumption of the charging pile 100 during the standby process.
[0040] In an optional embodiment, see Figure 1 As shown, the limit switch 120 is disposed on the outside of the charging gun holder 110. The charging gun holder 110 includes an opening 111 for docking the charging gun, and the limit switch 120 includes a trigger portion 123 that extends to the front side of the opening 111 and is triggered by the charging gun when the charging gun is inserted into the charging gun holder 110.
[0041] The limit switch 120 is set on the outside of the gun holder 110. The limit switch 120 is switched between the first state and the second state by the direct action of the charging gun on the trigger part 123. This facilitates the inspection and maintenance of the limit switch 120 and the use of the charging pile 100. At the same time, it facilitates the installation of the limit switch 120, optimizes the charging process of the charging pile 100, and reduces the operating cost of the charging pile 100.
[0042] In an optional embodiment, the limit switch 120 includes a reset part (not shown in the figure). The reset part acts on the trigger part 123. When the charging gun is not inserted into the gun holder 110, the trigger part 123 switches to a second state through the reset part. In some embodiments, the reset part may be elastic. When the charging gun is inserted into the gun holder, the charging gun acts on the trigger part 123, and the limit switch 120 switches to a first state, causing the reset part to be squeezed. When the charging gun is not inserted into the gun holder 110, the reset part acts on the trigger part 123 under the action of the elastic force, causing the limit switch 120 to automatically switch to the second state, so that the detection end 1211 of the limit switch 120 outputs a second signal A2 to the controller 140. The controller 140 can timely control the electronic components of the charging pile 100 to enter the start-up state, which facilitates the use of the charging pile 100.
[0043] In an optional embodiment, see Figure 1 As shown, the charging station 100 includes an outer wall 130. The charging gun holder 110 is recessed inward along the outer wall 130, and a trigger portion 123 is spaced apart from the outer wall 130. When the charging gun is inserted into the charging gun holder 110, the trigger portion 123 is abutted against the outer wall 130. The outer wall 130 limits the movement range of the limit switch 120, reducing the risk of damage to the limit switch 120 from excessive impact during the insertion of the charging gun into the charging gun holder 110, thus extending the service life of the charging station 100.
[0044] In an optional embodiment, see Figure 2 and Figure 3As shown, the limit switch 120 includes a first switch 121. The controller 140 includes a signal output terminal 141 and a signal input terminal 142. One end of the first switch 121 is connected to the signal output terminal 141, and the other end is a detection terminal 1211 connected to the signal input terminal 142. When the limit switch 120 is in the first state, the first switch 121 is closed. When the limit switch 120 is in the second state, the first switch 121 is open. The signal output terminal 141 of the controller 140 sends an electrical signal A. When the limit switch 120 is in the first state, the first switch 121 is closed, thereby converting the electrical signal A into a first signal A1 through the first state of the limit switch 120. After receiving the first signal A1, the signal input terminal 142 determines that the charging gun is in the reset state. At this time, the controller 140 controls the electronic components of the charging pile 100 to enter a standby state, thereby reducing the energy consumption of the charging pile 100 during the standby process; or the controller 140 determines that the charging pile 100 has completed the charging operation and the charging gun has returned to its position, and the controller 140 controls the charging process to enter the settlement and payment process after charging. When the limit switch 120 is in the second state, the first switch 121 is opened, thereby converting the electrical signal A into the second signal A2 through the second state of the limit switch 120, and the controller 140 controls the electronic components of the charging pile 100 to enter the start-up state.
[0045] In some other embodiments, the controller 140 may only include a signal input terminal 142. The charging pile 100 may be equipped with a signal output source, with one end of the first switch 121 connected to the signal output source and the other end serving as a detection terminal 1211 connected to the signal input terminal 142 of the controller 140.
[0046] In an optional embodiment, see Figure 2 and Figure 3 As shown, the charging pile 100 includes an AC-DC converter 180 and a notification device 190. The charging pile 100 has an external AC power input terminal 160, which is connected to the AC-DC converter 180. The limit switch 120 includes a second switch 122, which is connected to both the AC-DC converter 180 and the notification device 190.
[0047] When limit switch 120 is in the first state, second switch 122 is opened, AC-DC converter 180 is disconnected from prompting device 190, and prompting device 190 is closed.
[0048] When the limit switch 120 is in the second state, the second switch 122 is closed, the AC-DC converter 180 connects to the prompting device 190 and supplies power to the prompting device 190, at which time the prompting device 190 is activated.
[0049] With the above settings, when the limit switch 120 is in the first state, the indicator device 190 is turned off, thereby reducing the energy consumption of the indicator device 190 during the standby process of the charging pile 100. When the limit switch 120 switches to the second state, the controller 140 determines that the charging gun has been removed and is in use, and activates the indicator device 190 to inform the user that the charging gun is in use. The change in the state of the indicator device 190 between the charging gun being inserted into the gun holder 110 and not being inserted into the gun holder 110 makes it easier for the user to observe the status of the charging gun, thus facilitating the use of the charging pile 100.
[0050] In an optional embodiment, the limit switch 120 is a double-pole double-throw switch. When the limit switch 120 is in the first state, the first switch 121 is closed and the second switch 122 is open. When the limit switch 120 is in the second state, the first switch 121 is open and the second switch 122 is closed. This allows for simultaneous adjustment of the states of the first switch 121 and the second switch 122, simplifying the overall structure of the charging pile 100.
[0051] In other embodiments, the first switch 121 and the second switch 122 may also be set separately, or the open and closed states of the limit switch 120 in the first state and the second state may be adjusted according to the design requirements of the charging pile 100. This application does not impose any restrictions on this.
[0052] In an optional embodiment, the prompting device 190 includes at least one of an audio prompting device 190 and a light prompting device 190. The light prompting device 190 may be an LED light strip. During the use of the charging gun, the prompting device 190 can indicate the current usage status of the charging gun to the user. In cases where multiple charging stations 100 are provided, it facilitates the user's quick location of an available charging station 100 for charging, thereby facilitating the use of the charging stations 100.
[0053] In an optional embodiment, the charging pile 100 further includes an AC input terminal 160 and a start switch 170. One end of the start switch 170 is connected to the AC input terminal 160, and the other end is connected to the input terminal of the AC-DC converter 180. The start switch 170 controls the overall start and stop states of the charging pile 100. The output terminal of the AC-DC converter 180 is connected to a second switch 122 and a controller 140 to supply power to the controller 140. This configuration allows the indicator device 190 and the controller 140 to be connected in parallel, and the opening and closing of the second switch 122 does not affect the power supply from the AC-DC converter 180 to the controller 140. When the limit switch 120 switches from the second state to the first state, the controller 140 does not need to be powered on. Under the action of the first signal A1, it can quickly control the electronic components of the charging pile 100 to enter the start state, responding to user needs and improving the user experience of the charging pile 100.
[0054] In an optional embodiment, see Figure 2 and Figure 3 As shown, the charging pile 100 also includes a metering module 150. The metering module 150 is electrically connected to the output of the AC-DC converter 180 and to the controller 140. The metering module 150, through its electrical connection with the controller 140, acquires information such as the usage time of the charging gun and the duration of the limit switch 120 switching to its first state to calculate the charge for the electric vehicle using the charging gun, and feeds back the calculation information to the controller 140. This configuration creates a parallel connection between the prompting device 190, the controller 140, and the metering module 150. The opening and closing of the second switch 122 does not affect the power supply from the AC-DC converter 180 to the controller 140 and the metering module 150. When the limit switch 120 switches from its second state to its first state, the metering module 150 does not need to be activated, thus responding to user needs and improving the user experience of the charging pile 100.
[0055] It should be noted that the technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
