The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0043] The following describes in detail a charging pile 100 provided in an embodiment of the present application through a specific embodiment in conjunction with all the drawings in the specification.

[0044] Please refer to Figures 1 to 5 In one embodiment of the present application, a charging pile 100 is disclosed, comprising a cabinet 10, a main control module 20, and an auxiliary wrench 30. The cabinet 10 includes an electrical socket 11, which has an insertion port 101 and an installation cavity 102. The insertion port 101 communicates with the installation cavity 102. The electrical socket 11 and the insertion port 101 are located on opposite sides of the installation cavity 102, respectively. The electrical socket 11 is disposed adjacent to the installation cavity 102. The cavity wall of the installation cavity 102 has a clearance groove 104. The clearance groove 104 is located at the insertion port 101, and the groove wall of the clearance groove 104 includes a first abutting wall 12. The main control module 20 includes a circuit board 22, an end plate 24, and an electrical plug 26. The circuit board 22 is mounted within the installation cavity 102. With the insertion opening 101 pointing toward the electrical outlet 11, the circuit board 22 includes a first side 222 and a second side 224 disposed opposite each other. The end plate 24 is mounted on the first side 222, and the electrical plug 26 is mounted on the second side 224. The electrical plug 26 is used to electrically connect to the electrical outlet 11. An auxiliary wrench 30 is rotatably connected to the end plate 24 and includes a first protrusion 32 located within the clearance groove 104. The first abutment wall 12 and the first protrusion 32 are arranged sequentially from the first side 222 to the second side 224.

[0045] Among them, the auxiliary wrench 30 can be rotated to a first position or a second position. When the auxiliary wrench 30 is in the first position, the first protrusion 32 abuts against the first abutting wall 12, and the first abutting wall 12 presses the first protrusion 32, so that the electrical plug 26 is inserted into the electrical socket 11; when the auxiliary wrench 30 is in the second position, the first protrusion 32 is separated from the first abutting wall 12, so that the circuit board 22 can be inserted into or pulled out of the installation cavity 102.

[0046] Generally, in order to make the electrical connection between the circuit board 22 and the cabinet 10 more stable, an interference fit is adopted between the electrical plug 26 and the electrical socket 11. With the above structure, during the assembly process of the main control module 20 and the cabinet 10, the circuit board 22 is first inserted into the installation cavity 102 from the insertion port 101 so that the electrical plug 26 is aligned with the corresponding electrical socket 11. Then, the auxiliary wrench 30 is rotated to the first position, and the first abutting wall 12 presses against the first protrusion 32. The first protrusion 32 is subjected to a force in the direction from the first side 222 to the second side 224. Then, force is continued to be applied to the auxiliary wrench 30 so that the auxiliary wrench 30 continues to rotate (see FIG. 2 ). Figure 5 ), driving the main control module 20 to move along the direction from the first side 222 to the second side 224, so that the electrical plug 26 can be inserted into the electrical socket 11; further, in this embodiment, with the help of the auxiliary wrench 30, the electrical plug 26 is easier to insert into the electrical socket 11.

[0047] Specifically, in this embodiment, the cabinet 10 has a structure similar to a rectangular parallelepiped. The cabinet 10 has two installation cavities 102, and the two installation cavities 102 are arranged in sequence along the horizontal direction. Each installation cavity 102 corresponds to two circuit boards 22, and the two circuit boards 22 located in the same installation cavity 102 are arranged in sequence from top to bottom; the cabinet 10 includes an installation side panel 14 and a shell 15, and the installation side panel 14 is installed in the shell 15; each installation cavity 102 is formed between the two installation side panels 14, and a clearance groove 104 is opened on the installation side panel 14, and the clearance groove 104 is a rectangular through groove.

[0048] The circuit board 22 is a rectangular sheet-like structure, and the end plate 24 is detachably connected to the circuit board 22 via bolts. The circuit board 22 is located within the mounting cavity 102. When the electrical plug 26 is mated with the electrical socket 11, the end plate 24 is bolted to the cabinet 10. The end plate 24 includes handles 242 located on either side of the end plate 24. The user can use the handles 242 to pull the end plate 24, causing the circuit board 22 to extend from the insertion port 101 into the mounting cavity 102. The circuit board 22 is used to distribute electrical energy as needed to the various electronic components in the charging station 100.

[0049] Two auxiliary wrenches 30 are connected to each end plate 24, and the two auxiliary wrenches 30 are respectively located on both sides of the end plate 24; the auxiliary wrench 30 has a flat structure as a whole, the first protrusion 32 is roughly a triangular prism structure, and the end face of the first protrusion 32 is a right triangle. One end of the auxiliary wrench 30 is rotatably connected to the end plate 24 through a rotating shaft 33, the first protrusion 32 and the rotating shaft 33 are located at the same end of the auxiliary wrench 30, and the other end of the auxiliary wrench 30 is used for the user to hold.

[0050] In other embodiments, the cabinet 10 can also be in other shapes, such as a cylinder; multiple circuit boards 22 can correspond to the same installation cavity 102; the clearance groove 104 can also be in other shapes, such as a circle or a hexagon, and the clearance groove 104 can also be opened at other positions, such as the bottom cavity wall of the installation cavity 102; the number of auxiliary wrenches 30 can also be other, for example, each end plate 24 corresponds to an auxiliary wrench 30; the end plate 24 can also be fixedly connected to the circuit board 22 by welding.

[0051] The end plate 24 may include a sheet-shaped bent portion 241, which is parallel to the circuit board 22. The projection of the sheet-shaped bent portion 241 is located within the projection of the circuit board 22 in a direction perpendicular to the circuit board 22. A grounding metal sheet may be provided on the sheet-shaped bent portion 241 to ground the circuit board 22. Furthermore, the sheet-shaped bent portion 241 is located between the two mounting side plates 14, with one side of the sheet-shaped bent portion 241 abutting against one of the mounting side plates 14, and the other opposite side of the sheet-shaped bent portion 241 abutting against the other mounting side plate 14. Consequently, the mounting side plates 14 at the first side 222 limit the circuit board 22 via the sheet-shaped bent portion 241, allowing the circuit board 22 to be more stably installed within the mounting cavity 102, thereby reducing shaking of the main control module 20 relative to the cabinet 10.

[0052] Please refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, the auxiliary wrench 30 includes a main body 36, a gripping portion 38, a first abutting surface 322 and a second abutting surface 342. The main body 36 includes a first connecting end 362 and a second connecting end 364. The first connecting end 362 is rotatably connected to the end plate 24. The first protrusion 32 is connected to the first connecting end 362. The gripping portion 38 is connected to the second connecting end 364. The gripping portion 38 is located on one side of the main body 36, and the first protrusion 32 and the second protrusion 34 are both located on the other opposite side of the main body 36.

[0053] The first abutting surface 322 is disposed on the first protrusion 32 , and the second abutting surface 342 is disposed on the second protrusion 34 .

[0054] When the auxiliary wrench 30 is in the first position, the first abutting surface 322 abuts against the first abutting wall 12, and the second abutting surface 342 is separated from the second abutting wall 13; when the auxiliary wrench 30 is in the second position, the first abutting surface 322 is separated from the first abutting wall 12, and the second abutting surface 342 is separated from the second abutting wall 13; when the auxiliary wrench 30 is in the third position, the second abutting surface 342 abuts against the second abutting wall 13, and the first abutting surface 322 is separated from the first abutting wall 12.

[0055] Through the above structure, the grip portion 38 and the first protrusion 32 are respectively located on opposite sides of the main body 36, and the first protrusion 32 and the second protrusion 34 are located on the same side of the main body 36. The user can more easily apply force to the auxiliary wrench 30 through the grip portion 38 to rotate the auxiliary wrench 30.

[0056] In addition, the first connecting end 362 is rotatably connected to the end plate 24, the first protrusion 32 is connected to the first connecting end 362, and the gripping portion 38 is connected to the second connecting end 364, so that the distance between the gripping portion 38 and the rotation axis of the auxiliary wrench 30 is farther, and the distance between the first protrusion 32 and the rotation axis of the auxiliary wrench 30 is closer. The torque of the gripping portion 38 is longer than the torque of the first protrusion 32, and the user can save more effort when rotating the auxiliary wrench 30.

[0057] Specifically, the gripping portion 38, the first abutting surface 322, and the second abutting surface 342 are parallel to each other, and the gripping portion 38 is perpendicular to the body 36. In this embodiment, the body 36 and the gripping portion 38 are both bar-shaped blocks, and a rectangular through-slot is provided at one end of the gripping portion 38 facing away from the body 36. Projected onto the reference plane in the elongated direction of the body 36, the length of the gripping portion 38 is greater than the length of the first protrusion 32, and the length of the gripping portion 38 is also greater than the length of the second protrusion 34. The first connecting end 362 is sleeved on the rotating shaft 33, and the rotating shaft 33 is mounted on the end plate 24. The rotating shaft 22 can rotate relative to the end plate 24, so that the first connecting end 362 is rotatably connected to the end plate 24. The first connecting end 362 can rotate relative to the rotating shaft 33, or the first connecting end 362 is fixed to the rotating shaft 33.

[0058] In other embodiments, the grip portion 38 may also be other structures, such as a cylinder; the body 36 may also be other structures, such as an arc-shaped block structure.

[0059] In some embodiments, the auxiliary wrench 30 also includes a second protrusion 34, and the cabinet 10 also includes a second abutment wall 13; in the direction from the first side 222 to the second side 224, the second protrusion 34, the second abutment wall 13, the first abutment wall 12 and the first protrusion 32 are arranged in sequence; the distance between the first protrusion 32 and the second protrusion 34 is greater than the distance between the first abutment wall 12 and the second abutment wall 13.

[0060] The auxiliary wrench 30 can be rotated between the first position and the third position. The second position is between the first position and the third position. Figure 6 When the auxiliary wrench 30 is in the first position, the first protrusion 32 abuts against the first abutting wall 12, and the second protrusion 34 is separated from the second abutting wall 13. Figure 7 When the auxiliary wrench 30 is in the second position, the first protrusion 32 is separated from the first abutting wall 12, and the second protrusion 34 is separated from the second abutting wall 13. Figure 8 When the auxiliary wrench 30 is located at the third position, the second protrusion 34 abuts against the second abutting wall 13 , and the second abutting wall 13 presses the second protrusion 34 , so that the electrical plug 26 is pulled out of the electrical socket 11 .

[0061] Through the above structure, during the disassembly process of the main control module 20 and the cabinet 10, the auxiliary wrench 30 is first rotated to the third position, the second abutting wall 13 presses the second protrusion 34, and the second protrusion 34 is subjected to a force in the direction from the second side 224 to the first side 222; then, force is continued to be applied to the auxiliary wrench 30, so that the auxiliary wrench 30 continues to rotate, driving the main control module 20 to move along the direction from the second side 224 to the first side 222, so that the electric plug 26 can be pulled out of the electric socket 11, and finally, the end plate 24 is pulled to drive the circuit board 22 to extend out of the installation cavity 102 from the insertion port 101; and thus in this embodiment, with the help of the auxiliary wrench 30, the electric plug 26 is easier to be pulled out of the electric socket 11.

[0062] Specifically, in this embodiment, the first protrusion 32 is generally a triangular prism, with the end surface of the first protrusion 32 forming a right triangle. The second protrusion 34 is also generally a triangular prism, with the end surface of the second protrusion 34 also forming a right triangle. The outer edge of the mounting side panel 14 at the insertion opening 101 forms the second abutment wall 13. Both the first abutment wall 12 and the second abutment wall 13 are located between the first protrusion 32 and the second protrusion 34, with the first abutment wall 12 being closer to the electrical plug 26 than the second abutment wall 13.

[0063] In other embodiments, the second protrusion 34 may also be other structures, such as a cuboid or a cylinder.

[0064] In some embodiments, the charging pile 100 may include multiple main control modules 20, each main control module 20 includes an end plate 24, and each end plate 24 is equipped with two auxiliary wrenches 30. The two auxiliary wrenches 30 on the same end plate 24 are respectively located on both sides of the end plate 24.

[0065] Through the above structure, during the assembly process of the main control module 20 and the cabinet 10, the two auxiliary wrenches 30 on the same end plate 24 are rotated to the first position, and force is applied to the two auxiliary wrenches 30 at the same time, so that the end plate 24 can drive the circuit board 22 to move in the direction from the first side 222 to the second side 224. Then, during the process of inserting the electric plug 26 into the electric socket 11, the circuit board 22 is not easy to tilt relative to the cabinet 10, which makes it easier for the electric plug 26 to cooperate with the electric socket 11.

[0066] In addition, during the disassembly of the main control module 20 and the cabinet 10, the two auxiliary wrenches 30 on the same end plate 24 are rotated to the third position, and force is applied to the two auxiliary wrenches 30 at the same time, so that the end plate 24 can drive the circuit board 22 to move from the second side 224 to the first side 222. In the process of unplugging the electric plug 26 from the electric socket 11, the circuit board 22 is also not easy to tilt relative to the cabinet 10, which makes it easier for the electric plug 26 to be unplugged from the electric socket 11.

[0067] Specifically, the two auxiliary wrenches 30 on each end plate 24 are symmetrically distributed along the central axis of the end plate 24 .

[0068] Please refer to Figure 9 and Figure 10 In some embodiments, the charging pile 100 further includes a screw 40, and the auxiliary wrench 30 includes a rotating shaft 33. The rotating shaft 33 is rotatably connected to the end plate 24. The rotating shaft 33 defines a mounting through-hole 3302. The screw 40 is sequentially inserted through the circuit board 22, the mounting through-hole 3302, and the end plate 24. The screw 40 rotates relative to the mounting through-hole 3302, causing the screw 40 to press against the circuit board 22. When the circuit board 22 and the end plate 24 clamp the auxiliary wrench 30, the auxiliary wrench 30 is fixed relative to the end plate 24. The screw 40 rotates relative to the mounting through-hole 3302, creating a gap between the auxiliary wrench 30 and the circuit board 22, allowing the auxiliary wrench 30 to rotate relative to the end plate 24.

[0069] With the above structure, when the main control module 20 is installed in the cabinet 10, the auxiliary wrench 30 is locked by the screw 40 to prevent the auxiliary wrench 30 from accidentally rotating under the action of external forces. When the main control module 20 needs to be installed or removed from the cabinet 10, the screw 40 loosens the auxiliary wrench 30, allowing the auxiliary wrench 30 to rotate to the first position or the third position.

[0070] Specifically, in this embodiment, the mounting through-hole 3302 is a threaded hole. A screw 40 is sequentially inserted through the circuit board 22, the mounting through-hole 3302, and the end plate 24. One end of the screw 40 is inserted into the mounting through-hole 3302 and threadedly engaged. When the screw 40 is rotated relative to the mounting through-hole 3302, the nut of the screw 40 presses against the circuit board 22, causing the circuit board 22 and the end plate 24 to clamp the auxiliary wrench 30, thereby tightening the auxiliary wrench 30. When the screw 40 is rotated in the opposite direction relative to the mounting through-hole 3302, the nut of the screw 40 moves away from the circuit board 22, increasing the distance between the nut of the screw 40 and the rotating shaft 33, thereby loosening the auxiliary wrench 30. This makes the operation of the screw 40 more convenient.

[0071] In other embodiments, the mounting through hole 3302 may also be a through hole, and a threaded hole is provided on the end plate 24 , and the screw 40 is threadedly engaged with the threaded hole on the end plate 24 .

[0072] Please refer to Figure 11 and Figure 12 In some embodiments, guide grooves 106 are defined on both side walls of the mounting cavity 102. The circuit board 22 further includes a third side 226 and a fourth side 228 disposed opposite each other. The first side 222, the second side 224, the third side 226, and the fourth side 228 are sequentially connected. When the circuit board 22 is inserted into the mounting cavity 102, the third side 226 and the fourth side 228 extend into the corresponding guide grooves 106.

[0073] Through the above structure, when the circuit board 22 is inserted into the installation cavity 102, the guide groove 106 guides both the third side 226 and the fourth side 228, so that the circuit board 22 can be inserted into the installation cavity 102 more smoothly. After the circuit board 22 is inserted into the installation cavity 102, the electrical plug 26 can be aligned with the electrical socket 11.

[0074] Specifically, the guide grooves 106 are strip-shaped structures, and the two guide grooves 106 corresponding to each circuit board 22 are located at the same height.

[0075] In some embodiments, the cabinet 10 includes two oppositely disposed mounting side panels 14 , the mounting cavity 102 is formed between the two mounting side panels 14 , and the clearance groove 104 and the guide groove 106 are both provided on the mounting side panels 14 .

[0076] With the above structure, during the production process of the cabinet 10 , the mounting side panel 14 is produced separately as a component, thereby making it easier to form the clearance groove 104 and the guide groove 106 on the mounting side panel 14 .

[0077] Specifically, in this embodiment, the number of mounting side panels 14 is four, and each two mounting side panels 14 form a group. A mounting cavity 102 is formed between each group of mounting side panels 14, and the two mounting cavities 102 are located at the same height and close to each other; two circuit boards 22 arranged in sequence from top to bottom can be installed in each mounting cavity 102.

[0078] In other embodiments, the number of mounting side panels 14 may be other, such as two, and each mounting cavity 102 may be provided with other numbers of circuit boards 22, such as one; the guide groove 106 may be provided with other structures, such as the guide groove 106 being a groove formed concavely relative to the surface of the mounting side panel 14 .

[0079] In some embodiments, the mounting side panel 14 is further provided with a guide flare 108 , which is connected to the corresponding guide groove 106 ; in the direction from the first side 222 to the second side 224 , the guide flare 108 and the guide groove 106 are arranged in sequence, and the cross-sectional area of ​​the guide flare 108 gradually decreases.

[0080] Through the above structure, when the second side 224 is located at the insertion port 101 , the guide expansion 108 can guide the third side 226 and the fourth side 228 , so that the third side 226 and the fourth side 228 enter the corresponding guide groove 106 .

[0081] In some embodiments, the mounting side panel 14 includes a folding piece 142 . A hexagonal through slot 1402 is defined on the mounting side panel 14 . The folding piece 142 is disposed at the side edge of the hexagonal through slot 1402 and the lower side of the mounting side panel 14 .

[0082] The hemming member 142 includes an inclined section 1424 and a parallel section 1422 connected to each other. The guide groove 106 is formed between two adjacent parallel sections 1422 , and the guide flare 108 is formed between two adjacent inclined sections 1424 .

[0083] Through the above structure, the hexagonal through-slot 1402 can connect the mounting cavity 102 with the outside world, thereby facilitating easier heat dissipation for the circuit board 22. Furthermore, the hexagonal through-slot 1402 can be formed by a stamping process, and the hexagonal through-slot 1402 can be directly formed by stamping the hexagonal through-slot 1402. The hexagonal through-slot 1402 is stamped to form the hexagonal through-slot 1402, so that the parallel section 1422 and the inclined section 1424 in the hexagonal through-slot 1402 are interconnected. This makes it easier to form the hexagonal through-slot 1402 at the hexagonal through-slot 1402, making the mounting side panel 14 easier to produce.

[0084] Specifically, the folding piece 142 is bent along the side edge of the hexagonal through groove 1402, so that the folding piece 142 includes a parallel section 1422 and an inclined section 1424 connected to each other, and the guide groove 106 is formed between the upper and lower adjacent parallel sections 1422; the inclined section 1424 corresponding to the folding piece 142 located above the guide groove 106 is inclined upward, and the inclined section 1424 corresponding to the folding piece 142 located below the guide groove 106 is inclined downward, and the guide flare 108 is formed between the upper and lower adjacent inclined sections 1424.

[0085] Each mounting side plate 14 is provided with four hexagonal through slots 1402. The hexagonal through slots 1402 correspond to each other in pairs, and the corresponding two hexagonal through slots 1402 are arranged one above the other. The upper and lower edges of the hexagonal through slots 1402 are both provided with folding pieces 142. In the two corresponding hexagonal through slots 1402, a guide groove 106 and a guide flare 108 are formed between the folding piece 142 at the lower edge of the lower hexagonal through slot 1402 and the folding piece 142 at the lower side of the mounting side plate 14. A guide groove 106 and a guide flare 108 are also formed between the folding piece 142 at the upper edge of the lower hexagonal through slot 1402 and the folding piece 142 at the lower edge of the upper hexagonal through slot 1402.

[0086] In some embodiments, the cabinet 10 also includes a guide column 16, and the main control module 20 also includes a guide member 28. The guide member 28 is installed on the second side 224. The guide member 28 is located on one side of the electrical plug 26. The guide member 28 is provided with a guide hole 2802. When the circuit board 22 extends into the installation cavity 102, the guide column 16 extends into the guide hole 2802.

[0087] Through the above structure, when the second side 224 extends into the installation cavity 102 and the electrical plug 26 approaches the electrical socket 11, the guide column 16 extends into the guide hole 2802, and the guide column 16 guides the guide member 28, so that the electrical plug 26 can be more accurately matched with the electrical socket 11.

[0088] Specifically, the guide column 16 has a structure similar to a cylinder, the central axis of the guide column 16 is set horizontally, one end of the guide column 16 is connected to the side cavity wall opposite to the cavity opening of the installation cavity 102, and the other end of the guide column 16 has a structure similar to a cone; the guide member 28 is a block structure, and the guide member 28 is connected to the circuit board 22 through a threaded connection. The guide member 28 is located on one side of the electric plug 26, and the guide member 28 and the electric plug 26 are at the same height.

[0089] In some embodiments, a heat dissipation structure may be installed on the surface of the circuit board 22 , and the heat dissipation structure may be a fin heat sink or a miniature fan structure.
