Description

Technical Field

[0001] This disclosure relates to the field of energy technology, and in particular to a charging pile. Background Technology

[0002] A charging station includes a station body, a charging gun, and a cable. One end of the cable connects to the station body, and the other end connects to the charging gun. The charging gun is inserted into the charging port of an electric vehicle. The station body also has a charging port; when not using the charging station, the charging gun is inserted into this port.

[0003] In related technologies, the charging gun head includes a latch, and the insertion hole has a latch groove. When the charging gun head is inserted into the insertion hole, the latch locks with the latch groove, thus locking the charging gun head in the insertion hole.

[0004] However, due to the stiffness of the cable and the large size of the charging gun head, it is difficult to accurately insert the charging gun head into the charging port of the charging station. This can cause the locking buckle to fail to engage with the locking groove, resulting in the charging gun head falling and being damaged. Moreover, during the insertion and removal process, the locking buckle and locking groove may wear down or even fail. Utility Model Content

[0005] This disclosure provides a charging pile. The charging gun head of the charging pile can be stably attached to the insertion hole of the pile body by magnetic attraction, reducing the possibility of the charging gun head falling and being damaged. The technical solution of the charging pile is as follows.

[0006] This disclosure provides a charging station. The charging station includes a station body, a charging gun head, and a cable, with one end of the cable connected to the station body and the other end connected to the charging gun head. The station body includes a charging port and an electromagnet, with the electromagnet located inside the charging port. The charging gun head includes a magnetic component, and when the charging gun head is inserted into the charging port, the magnetic component generates a magnetic attraction force with the electromagnet.

[0007] An electromagnet can also be called an electromagnetic coil. A magnetic component is a part that can be attracted by an electromagnet, such as an iron sheet. The charging gun head and cable together form the charging gun.

[0008] The technical solution disclosed herein allows the user to return the charging gun by inserting the charging gun head into the charging port. A magnetic attraction is generated between the electromagnet and the magnetic component, causing the charging gun head to stably adhere to the port. When the user needs to charge the charging gun, the user de-energizes the electromagnet, causing the magnetic attraction between the electromagnet and the magnetic component to disappear, allowing the user to remove the charging gun head normally.

[0009] Compared to technical solutions that use latches and latch slots to confine the charging gun head to the charging port, the technical solution provided in this disclosure allows the charging gun head to continue being inserted into the charging port even if it is not fully inserted, under the action of magnetic attraction, and to be stably attracted to the charging port, reducing the possibility of the charging gun head falling and being damaged. Furthermore, since a latch slot is not required in the charging port, there will be no wear between the latch and the latch slot during the removal and return of the charging gun from the charging station, reducing the possibility of latch damage. This, in turn, improves the reliability of the latch locking with the latch slot on the electric vehicle's charging port, further reducing the possibility of the charging gun head falling and being damaged.

[0010] In one implementation, the charging station also includes a control board for controlling the energization and de-energization of the electromagnet. The charging gun head also includes a first unlocking component, which is communicatively connected to the control board. When triggered, the first unlocking component sends a message to the control board instructing it to de-energize the electromagnet. Specifically, when the user needs to remove the charging gun head from the insertion hole, the user holds the charging gun head and triggers the first unlocking component, which then instructs the control board to de-energize the electromagnet. After the electromagnet is de-energized, the magnetic attraction between the electromagnet and the magnetic component disappears, allowing the user to normally remove the charging gun head.

[0011] In one implementation, the first unlocking component includes an unlocking button and a trigger. The unlocking button is used to press the trigger. The trigger is communicatively connected to a control board and, when pressed, sends a message to the control board instructing it to de-energize the electromagnet. Specifically, when the user needs to remove the charging gun head from the insertion hole, the user holds the charging gun head and presses the unlocking button, which presses the trigger, instructing the control board to de-energize the electromagnet.

[0012] In one implementation, the charging gun head also includes a latch for locking with a latch slot within the vehicle's charging port. An unlock button is also used to release the latch. That is, this disclosure reuses the unlock button that controls the latch to press the trigger. Thus, the user's operation of pulling the charging gun head off the charging station is the same as that in related technologies: first press the unlock button, then pull the charging gun head out. The user does not need to spend extra effort relearning how to operate the charging gun head.

[0013] In one implementation, the cable includes a signal line, through which the first unlocking component communicates with the control board. This makes the communication connection between the first unlocking component and the control board more reliable.

[0014] In one implementation, the charging station also includes a control board and a second unlocking component. The control board controls the energization of the electromagnet. The second unlocking component, when triggered, sends a message to the control board instructing it to de-energize the electromagnet. Specifically, when the user needs to remove the charging gun from the insertion port, the user holds the charging gun in one hand and triggers the second unlocking component with the other. The second unlocking component then instructs the control board to de-energize the electromagnet. After the electromagnet is de-energized, the magnetic attraction between the electromagnet and the magnetic component disappears, allowing the user to remove the charging gun normally. By incorporating the second unlocking component into the charging station, modifications to the charging gun are reduced.

[0015] In one implementation, the electromagnet is located at the bottom of the charging gun hole, and the magnetic component is located at the end of the charging gun head furthest from the cable. Thus, in the insertion direction of the charging gun head, the magnetic component and the electromagnet are positioned opposite each other, and the magnetic attraction between them allows the charging gun head to be stably attached to the charging gun hole.

[0016] In one implementation, the magnetic component is embedded inside the housing of the charging gun head and is in the form of a sheet. The magnetic component includes multiple clearance holes. These clearance holes correspond one-to-one with multiple terminal holes on the end face of the charging gun head, and each terminal hole is fitted with a corresponding terminal hole. In this way, the magnetic component does not obstruct the normal connection between the charging gun head and the charging port of the electric vehicle.

[0017] In one implementation, the electromagnet is arranged circumferentially along the inner wall of the charging gun hole, and when the charging gun head is inserted into the hole, the electromagnet surrounds the magnetic component. In this way, the electromagnet is not located in the insertion direction of the charging gun head, so it does not affect the insertion of the charging gun head, providing more leeway for the insertion depth and facilitating user operation.

[0018] In one implementation, the charging gun head also includes a latch for locking with a latch slot within the vehicle's charging port. The magnetic component is positioned forward relative to the latch. This prevents the latch from being located between the annular electromagnet and the magnetic component, thus reducing the distance between them and increasing the magnetic attraction between them.

[0019] In one implementation, a magnetic component is embedded inside the housing of the charging gun head and is ring-shaped. The magnetic component surrounds multiple terminal holes on the end face of the charging gun head. In this way, the magnetic component does not obstruct the normal connection between the charging gun head and the charging port of the electric vehicle.

[0020] In one implementation, the magnetic component is embedded inside the housing of the charging gun head. Attached Figure Description

[0038] With the rapid development of the new energy vehicle industry, the driving range of electric vehicles is constantly improving, and battery capacity is also increasing. To achieve rapid recharging of electric vehicles, higher requirements are placed on charging power. Charging piles are used to recharge electric vehicles. A charging pile includes a pile body, a charging gun, and a cable. One end of the cable connects to the pile body, and the other end connects to the charging gun. The charging gun is inserted into the charging port of the electric vehicle, and the pile body can charge the electric vehicle through the cable and the charging gun. Furthermore, the pile body also includes a gun insertion hole; when charging is not needed, the charging gun is inserted into the insertion hole. The charging gun and the cable together constitute the charging gun.

[0039] As charging power increases, cables also become thicker, which affects the overall ease of use of the charging gun. Especially during the insertion and return of the gun to the charging station, due to the stiffness of the cable and the large size of the charging gun head, it is difficult to accurately insert the charging gun head into the insertion hole of the charging station. This causes the charging gun head to detach from the insertion hole and fall to the ground, resulting in damage to the charging gun head.

[0040] Figure 1 A schematic diagram of a charging gun head is shown. (For example...) Figure 1 As shown, the charging gun head 2 includes a latch 23 and an unlock button 221, as... Figure 2 As shown, the latch 23 is used to lock with the latch slot 10 on the vehicle's charging port. When the user presses the unlock button 221, the latch 23 disengages from the latch slot 10, allowing the charging gun head 2 to be pulled out of the vehicle's charging port.

[0041] To reduce the possibility of the charging gun head 2 falling off the pile, a locking groove 10 is also provided in the insertion hole of the pile. When the charging gun head 2 is inserted into the insertion hole, the latch 23 will lock into the locking groove 10 in the insertion hole.

[0042] However, on the one hand, due to the stiffness of the cable and the large size of the charging gun head, it is difficult to accurately insert the charging gun head 2 into the appropriate position of the charging port, resulting in the latch 23 not locking properly with the latch groove 10. On the other hand, during long-term use, the latch 23 and the latch groove 10 may wear down or even fail. All of these factors increase the likelihood of the charging gun head 2 falling and being damaged from the charging station. Furthermore, after the latch 23 wears down, the locking mechanism between the latch 23 and the latch groove 10 of the electric vehicle's charging port is also prone to failure, further increasing the possibility of the charging gun head 2 falling and being damaged.

[0043] In view of the above-mentioned technical problems, this disclosure provides a charging pile. Figure 3 A schematic diagram of a charging pile provided in an embodiment of this disclosure is shown. Figure 3As shown, the charging station includes a station body 1, a charging gun head 2, and a cable 3. One end of the cable 3 is connected to the station body 1, and the other end is connected to the charging gun head 2. The station body 1 includes a charging gun hole 11 and an electromagnet 12. The charging gun head 2 includes a magnetic component 21, and when the charging gun head 2 is inserted into the charging gun hole 11, the magnetic component 21 generates a magnetic attraction force with the electromagnet 12.

[0044] The electromagnet 12 can also be called an electromagnetic coil. The magnetic component 21 is a part that can be attracted by the electromagnet 12, such as an iron sheet or an iron ring. The magnetic component 21 can be embedded inside the housing of the charging gun head 2, for example, the magnetic component 21 can be embedded into the housing of the charging gun head 2 using injection molding or other processes.

[0045] The technical solution provided in this embodiment allows the user to return the charging gun by inserting the charging gun head 2 into the charging port 11. A magnetic attraction is generated between the electromagnet 12 and the magnetic component 21, causing the charging gun head 2 to stably adhere to the charging port 11. When the user needs to charge the charging gun head 2, the user de-energizes the electromagnet 12, causing the magnetic attraction between the electromagnet 12 and the magnetic component 21 to disappear, allowing the user to normally remove the charging gun head 2.

[0046] Compared to the technical solution that uses the latch 23 and latch groove 10 to limit the charging gun head 2 to the insertion hole 11, the technical solution provided in this embodiment allows the charging gun head 2 to continue to be inserted into the insertion hole 11 under the action of magnetic attraction, even if it is not fully inserted, and to be stably attracted in the insertion hole 11, reducing the possibility of the charging gun head 2 falling and being damaged. Moreover, since the latch groove 10 does not need to be provided in the insertion hole 11, there will be no wear between the latch 23 and the latch groove 10 during the process of pulling the gun out of the charging station 1 and returning the gun, reducing the possibility of damage to the latch 23, and thus improving the reliability of the latch 23 locking with the latch groove 10 on the charging port of the electric vehicle.

[0047] The positions and structures of the electromagnet 12 and the magnetic component 21 will be described below by way of example.

[0048] In some examples, such as Figure 3 As shown, the electromagnet 12 is located at the bottom of the charging gun hole 11, and the magnetic component 21 is located at the front end 20 of the charging gun head 2. The front end 20 of the charging gun head 2 is the end of the charging gun head 2 furthest from the cable 3. Thus, in the insertion direction of the charging gun head 2, the magnetic component 21 and the electromagnet 12 are positioned opposite each other, and the magnetic attraction generated between them allows the charging gun head 2 to be stably attached to the charging gun hole 11. The rear end of the charging gun head 2 is connected to the cable 3.

[0049] Figure 4 A schematic diagram of a charging gun head 2 is shown. (As shown) Figure 4As shown, the front end 20 of the charging gun head 2 is provided with multiple terminal holes 201, which contain power supply terminals, signal terminals, etc. It is understood that the magnetic component 21 should not block the terminal holes 201 to avoid affecting the normal connection between the charging gun head 2 and the charging port of the electric vehicle. In some examples, such as... Figure 5 and Figure 6 As shown, the magnetic component 21 is sheet-shaped and embedded inside the housing of the charging gun head 2. The magnetic component 21 includes multiple clearance holes 210, which correspond one-to-one with multiple terminal holes 201 of the charging gun head 2, and the multiple clearance holes 210 respectively fit over the multiple terminal holes 201.

[0050] In other examples, such as Figure 7 As shown, the magnetic component 21 is ring-shaped and surrounds multiple terminal holes 201 circumferentially. This ensures that the magnetic component 21 does not obstruct the normal connection between the charging gun head 2 and the charging port of the electric vehicle. Specifically, to improve the attraction force, such as... Figure 7 As shown, it is set in the insertion / removal direction of the charging gun head 2 ( Figure 7 (In the direction of the arrow in the image), the magnetic component 21 is flat.

[0051] In other examples, such as Figure 8 and Figure 9 As shown, the electromagnet 12 is ring-shaped (i.e., the electromagnet 12 is arranged circumferentially along the inner wall of the charging gun hole 11), and when the charging gun head 2 is inserted into the charging gun hole 11, the electromagnet 12 surrounds the magnetic component 21. In this way, the electromagnet 12 is not located in the insertion direction of the charging gun head 2, so the electromagnet 12 will not affect the insertion of the charging gun head 2, providing more leeway for the insertion depth and facilitating user operation. In some examples, the magnetic component 21 is also ring-shaped.

[0052] In some examples, such as Figure 9 and Figure 10 As shown, the magnetic component 21 is positioned forward relative to the latch 23, meaning that the magnetic component 21 is closer to the end of the charging gun head 2 furthest from the cable 3. This prevents the latch 23 from being located between the annular electromagnet 12 and the magnetic component 21, allowing for a smaller distance between them and increasing the magnetic attraction between them.

[0053] In some examples, such as Figure 10 and Figure 11 As shown, the magnetic component 21 is ring-shaped and embedded inside the housing of the charging gun head 2. The magnetic component 21 circumferentially surrounds multiple terminal holes 201. In this way, the magnetic component 21 will not obstruct the normal connection between the charging gun head 2 and the charging port of the electric vehicle. To improve the attraction force, such as... Figure 11 As shown, it is disposed radially on the annular magnetic element 21. Figure 11 (In the direction of the arrow in the image), the magnetic component 21 is flat.

[0054] The following is an exemplary description of how the electromagnet 12 is powered on and off.

[0055] (1) In some examples, such as Figure 12 As shown, the pile body 1 also includes a control board 13, which is used to control the power supply to and from the electromagnet 12. The charging gun head 2 also includes a first unlocking component 22, which is communicatively connected to the control board 13. When triggered, the first unlocking component 22 sends a message to the control board 13 instructing the control board 13 to de-energize the electromagnet 12.

[0056] When returning the charging gun, the user holds the charging gun head 2 and inserts it into the charging port 11. A magnetic force is generated between the electromagnet 12 and the magnetic component 21, causing the charging gun head 2 to stably adhere to the port 11. When the user needs to charge the charging gun head 2, the user holds the charging gun head 2 and triggers the first unlocking component 22. The first unlocking component 22 then instructs the control board 13 to de-energize the electromagnet 12. After the electromagnet 12 is de-energized, the magnetic force between the electromagnet 12 and the magnetic component 21 disappears, and the user can normally remove the charging gun head 2.

[0057] In some examples, such as Figure 12 As shown, the first unlocking component 22 includes an unlocking button 221 and a trigger 222. The unlocking button 221 is used to squeeze the trigger 222. The trigger 222 is communicatively connected to the control board 13, and when squeezed, the trigger 222 sends a message to the control board 13 instructing it to de-energize the electromagnet 12. Specifically, when the user needs to charge the device using the charging gun head 2, the user presses the unlocking button 221, which squeezes the trigger 222, and the trigger 222 instructs the control board 13 to de-energize the electromagnet 12.

[0058] In some examples, such as Figure 12 As shown, the unlock button 221 is also used to release the locking of the latch 23. That is, this embodiment reuses the unlock button 211 that controls the latch 23 to press the trigger 222. In this way, the operation of the user pulling the charging gun head 2 out of the charging pile 1 provided in this embodiment is the same as the operation of pulling the charging gun head 2 out of the charging pile 1 in the related art, both of which involve pressing the unlock button 221 first and then pulling the charging gun head 2 outward. The user does not need to spend extra effort to relearn how to operate the charging gun head 2.

[0059] In some examples, the first unlocking component 22 (trigger 222) is also used to instruct the control board 13 to energize the electromagnet 12 after the target duration has elapsed. This ensures that the electromagnet 12 remains energized when the charging gun head 2 is reinserted into the insertion hole 11, thereby reducing the likelihood of the charging gun head 2 falling out. The target duration can be 3s-10s.

[0060] This disclosure does not limit the implementation method of the communication connection between the first unlocking component 22 and the control board 13. In some examples, such as Figure 12 As shown, cable 3 includes signal line 31, through which the first unlocking component 22 is communicatively connected to the control board 13. This makes the communication connection between the first unlocking component 22 and the control board 13 more reliable.

[0061] In other examples, the control panel 13 includes a first wireless communication component, the first unlocking component 22 includes a second wireless communication component, and the first and second wireless communication components are connected to each other wirelessly.

[0062] (2) In other examples, such as Figure 13 As shown, the pile body 1 also includes a control board 13 and a second unlocking component 14. The control board 13 is used to control the on / off state of the electromagnet 12. The second unlocking component 14 is used to send a message to the control board 13, instructing the control board 13 to de-energize the electromagnet 12, when triggered.

[0063] When returning the charging gun, the user inserts the charging gun head 2 into the charging port 11. A magnetic force is generated between the electromagnet 12 and the magnetic component 21, causing the charging gun head 2 to stably adhere to the port 11. When the user needs to charge the charging gun head 2, the user holds the charging gun head 2 with one hand and triggers the second unlocking component 14 with the other. The second unlocking component 14 then instructs the control board 13 to de-energize the electromagnet 12. After the electromagnet 12 is de-energized, the magnetic force between the electromagnet 12 and the magnetic component 21 disappears, and the user can normally remove the charging gun head 2.

[0064] This embodiment of the disclosure reduces the need for modifications to the charging gun head 2 by placing the second unlocking component 14 on the pile body 1.

[0065] This disclosure does not limit the implementation of the second unlocking component 14. In some examples, such as Figure 13As shown, the second unlocking component 14 also includes an unlocking button 221 and a trigger 222. The unlocking button 221 is used to squeeze the trigger 222. The trigger 222 is communicatively connected to the control board 13, and when squeezed, it instructs the control board 13 to de-energize the electromagnet 12. Specifically, when the user needs to charge the charging gun head 2, the user holds the charging gun head 2 with one hand and presses the unlocking button 221 with the other. The unlocking button 221 then squeezes the trigger 222, which instructs the control board 13 to de-energize the electromagnet 12. After the electromagnet 12 is de-energized, the magnetic attraction between the electromagnet 12 and the magnetic component 21 disappears, and the user can normally pull out the charging gun head 2.

[0066] In some examples, the second unlocking component 14 is also used to instruct the control board 13 to energize the electromagnet 12 after the target duration has been triggered. This ensures that the electromagnet 12 remains energized when the charging gun head 2 is inserted into the charging port 11, reducing the possibility of the charging gun head 2 falling out. The target duration can be 3-10 seconds.

[0067] It should be noted that the charging piles provided in this embodiment can be either integrated charging piles or split-type charging piles. For split-type charging piles, the split-type charging pile includes a charging host and one or more charging terminals. The charging host connects to one or more charging terminals and supplies power to the charging terminals. The charging terminal includes the aforementioned pile body 1, charging gun head 2, and cable 3.

[0068] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
