Implementation Method

[0009] In the following embodiments, the term "connection" is used in the context of electrical connection or signal transmission. "Connection" can refer to a physical connection, or a direct or indirect connection between physical components. Furthermore, the drawings of this invention are for illustrative purposes only and are not necessarily drawn to scale; not all details may be shown in the drawings.

[0010] To facilitate a full explanation of the charging device and its assembly of the present invention, the following will use a charging pile used in electric vehicles as an example. However, the application scope and the scope of protection claimed by the present invention will not be limited to the charging pile. Please refer to Figures 1, 2, 3 and 4. Figure 1 shows a perspective view of a charging pile according to an embodiment; Figure 2 shows an exploded view of the charging pile according to the embodiment; Figure 3 shows an exploded view (a) of the base 30 according to the embodiment; and Figure 4 shows a partial cross-sectional view at position 4-4 in Figure 1, with the movable member 35 located at the limiting position P2 indicated by a dashed line.

[0011] Referring to Figure 1, the charging pile includes a power connector 10 and a charging pile assembly. The charging pile is suitable for replenishing the on-board battery of an electric vehicle or plug-in hybrid vehicle. The charging pile assembly is suitable for providing a charging interface and monitoring current and voltage status. The power connector 10 is used to provide power to the charging pile assembly when plugged into it. The charging pile assembly includes a charging base 20 and a base 30 that can be combined. The charging base 20 includes, for example, but not limited to, a housing, a control panel, a charging socket, a cable adapter terminal block, and safety protection devices. In some embodiments, the charging pile is wall-mounted, and the base 30 is suitable for installation on a wall.

[0012] Referring to Figure 2, the power connector 10 includes a plurality of electrical terminals 15, which are respectively connected to a plurality of wires, such as, but not limited to, ground wire, live wire, and neutral wire. The power connector 10 is adapted to be inserted into the base 30. The charging base 20 includes a plurality of electrical contacts 25, which protrude toward the base plate 31 of the base 30. The base 30 includes a base plate 31 and a movable member 35. The base plate 31 is adapted to be engaged with the charging base 20, for example, the charging base 20 can be fitted onto the base plate 31. The base plate 31 has a insertion slot 310 corresponding to the electrical contacts 25 of the charging base 20. When the power connector 10 is plugged into the base 30, the power connector 10 is inserted into the socket 310 of the base plate 31. The electrical contacts 25 are electrically connected to the electrical terminals 15 (see Figure 2). The electrical terminals 15 and electrical contacts 25 can be, for example, but not limited to, copper plates. Furthermore, the power connector 10 inserted into the socket 310 can be securely fastened using locking fasteners 50 (e.g., screws or anti-theft screws). Therefore, the wiring inside the charging base 20 can be simplified, saving installation time and resulting in a clean and aesthetically pleasing appearance, offering ease of installation.

[0013] Referring to Figure 4, the movable member 35 is movably disposed on the base plate 31. The movable member 35 is located adjacent to the insertion slot 310, wherein in response to the power connector 10 being inserted into the insertion slot 310 of the base 30, the movable member 35 engages the charging base 20. That is, when the power connector 10 is inserted into the base 30, the movable member 35 limits the charging base 20 to the base plate 31, preventing the charging base 20 from detaching from the assembly with the base plate 31. Therefore, the movable member 35 prevents the charging base 20 and the base 30 from moving or separating relative to each other in at least one specific direction, thereby maintaining the assembly relationship between the charging base 20 and the base plate 31 of the base 30. In this way, the charging pile or charging pile assembly is not easily disassembled, thus having an anti-theft function.

[0014] Further, referring to FIG4, in some embodiments, the movable member 35 is slidably disposed on the base plate 31 and has a release position P1 and a limiting position P2, wherein in response to the power connector 10 being inserted into the insertion slot 310 of the base 30, the movable member 35 is located in the limiting position P2 to engage the charging base 20. When the movable member 35 is in the release position P1, the movable member 35 does not engage the charging base 20, allowing the charging base 20 to have a degree of freedom of movement relative to the base 30 in at least one specific direction. In some embodiments, the mounting plate 21 of the charging base 20 has a restraining portion 23, and the movable member 35 includes a resisting portion 351 and a locking portion 355. The movable member 35 is adapted to slide from the release position P1 toward the limiting position P2 by being driven by the power connector 10 through the resisting portion 351. When the movable member 35 is in the limiting position P2, the locking portion 355 of the movable member 35 engages the restrained portion 23 of the charging base 20 to prevent the charging base 20 from detaching from the base 30 (base plate 31). Conversely, when the movable member 35 is in the release position P1, the locking portion 355 of the movable member 35 does not engage the restrained portion 23 of the charging base 20, and the charging base 20 is suitable for detaching from the base 30. In some embodiments, when the charging base 20 is fitted onto the base plate 31 and the movable member 35 is in the release position P1, the charging base 20 has a single degree of freedom relative to the base plate 31. In other words, the movable member 35 can slide along the base plate 31 and selectively reside in the release position P1 and the limiting position P2. When the movable member 35 is in the limiting position P2, the movable member 35 fixes the charging base 20 to the base plate 31. When the charging base 20 is fitted onto the base plate 31 and the movable part 35 is in the release position P1, the charging base 20 has a single degree of freedom relative to the base plate 31.

[0015] The following describes the structural details of the charging pile assembly using an embodiment.

[0016] Referring to Figure 2, in some embodiments, the base plate 31 includes an insertion portion 312, and the charging base 20 includes a mating portion 200. The charging base 20 is coupled to the base plate 31 via the mating portion 200 and the insertion portion 312 of the base plate 31, so as to have a single degree of freedom of movement. Taking Figure 2 as an example, the insertion portion 312 is a flange protruding toward the mounting plate 21 of the charging base 20, and the position and number of flanges are not limited. The base plate 31 in Figure 2 has three insertion portions 312, one insertion portion 312b and two insertion portions 312a are located on the short side (bottom side) and long side (left side and right side) of the base plate 31, respectively. In some embodiments, the base 30 further includes at least one locking fastener 40 and at least one corresponding locking hole 316. Taking FIG2 as an example, the base plate 31 has at least one corresponding locking hole 316, and the locking fastener 40 is adapted to pass through the corresponding locking holes 316 of the charging base 20, the base plate 31, and the movable member 35. Specifically, the insertion portions 312a and 312b may be respectively provided with locking holes 316. When the insertion portions 312a and 312b are respectively inserted into the matching portions 200 of the opening type of the mounting plate 21, the charging base 20 can be locked to the base plate 31 by means of the locking fastener 40 (e.g., screws or anti-theft screws). In this way, the charging base 20 can only move relative to the base plate 31 in a single direction to engage or disengage from the base plate 31. The relative movement between the charging base 20 and the base plate 31 can only be along the protruding direction of the insertion portion 312 (e.g., the Z-axis in FIG2). In addition, the locking hole 316 may have other variations, which will be described in later embodiments.

[0017] Referring to Figure 4, in some embodiments, the sliding direction of the movable member 35 between the release position P1 and the limiting position P2 is substantially perpendicular to the single direction in which the charging base 20 has a degree of freedom of movement. Taking Figure 4 as an example, the charging base 20 is fitted onto the base plate 31. When the movable member 35 is in the release position P1, the charging base 20 can move relative to the base plate 31 along the Z-axis. The release position P1 is the normal position of the movable member 35 on the base plate 31 when the charging base 20 is fitted onto the base plate 31. Since the charging base 20 only has a degree of freedom of movement along the Z-axis, and the sliding direction of the movable member 35 between the release position P1 and the limiting position P2 is substantially parallel to the Y-axis, the sliding direction of the movable member 35 is substantially perpendicular to the Z-axis in which the charging base 20 has a degree of freedom of movement. In this way, the movable member 35 in the limiting position P2 can limit the charging base 20 to the base plate 31 and prevent it from disengaging along the Z-axis.

[0018] Referring to FIG3, in some embodiments, the movable member 35 includes a base plate 352, a receiving portion 351, and a locking portion 355. The receiving portion 351 and the locking portion 355 are located at opposite ends of the base plate 352 and protrude toward the mounting plate 21 (see FIG4). Referring to FIG4, the base plate 31 also includes a receiving groove 315 for receiving the movable member 35. The receiving groove 315 communicates with the insertion groove 310, and the receiving portion 351 is located in the insertion groove 310.

[0019] Referring to Figure 4, the movable member 35 is located in the receiving groove 315, and the abutting part 351 protrudes outward from the insertion groove 310. The through hole 210 of the mounting plate 21 of the charging base 20 corresponds to the receiving groove 315. The locking part 355 of the movable member 35 can pass through the receiving groove 315 and extend into the through hole 210, wherein the mounting plate 21 is located on the side of the charging base 20 facing the base plate 31. In this way, the movable member 35 can be hidden inside the charging pile assembly as a concealed fastener of the charging pile assembly.

[0020] Referring to Figure 4, in some embodiments, the movable member 35 is slidably disposed in the receiving groove 315. When the power connector 10 is inserted into the insertion groove 310, the power connector 10 abuts against the receiving part 351, making the movable member 35 suitable for moving to the limiting position P2. In other words, the movable member 35 is adapted to be pushed and driven by the power connector 10 when it is inserted into the insertion groove 310, and slides from the release position P1 to the limiting position P2. Specifically, referring to Figure 3, the fixing members 45a and 45b pass through the slide groove 353 of the movable member 35 and are fixed to the base plate 31. The distance between the fixing members 45a and 45b is less than the longitudinal length of the slide groove 353, that is, the length on the Y-axis. Thus, the movable member 35 slides on the fixing members 45a and 45b through the slide groove 353 and has a release position P1 and a limiting position P2. The aforementioned fixing members 45a and 45b are, for example, but not limited to, screws, rivets or other fixing elements. Further, referring to Figure 4, when the power connector 10 is not inserted into the insertion slot 310, the movable member 35 is in the released position P1, and the locking part 355 of the movable member 35 is not locked to the locking part 23 at the bottom edge of the through hole 210 of the charging base 20. When the power connector 10 is inserted into the insertion slot 310, the power connector 10 abuts against the abutting part 351 of the movable member 35 and drives the locking part 355 downward (in the -Y direction in the figure) to lock to the locking part 23 at the bottom edge of the through hole 210 of the charging base 20. That is to say, when the movable member 35 is in the limiting position P2, the locking part 355 can lock the mounting plate 21 to fix the charging base 20 to the base plate 31, and cannot disengage from the base plate 31 along the Z-axis.

[0021] Therefore, when the charging base 20 is fitted onto the base plate 31 and the movable member 35 is in the limiting position P2, the movable member 35 can fix the relative position between the charging base 20 and the base plate 31, preventing them from moving relative to each other in the Z-axis direction. In this way, when the power connector 10 is plugged into the charging pile assembly, the hidden buckle inside the charging pile assembly can be activated simultaneously, and the movable member 35 slides from the release position P1 to the limiting position P2, fixing the charging base 20 to the base plate 31. The charging pile or charging pile assembly is not easily removed and stolen. In other words, even if the locking device 40 (such as an anti-theft screw) used to secure the charging base 20 and the base 30 is intentionally damaged, the charging base 20 and the base 30 will still be secured by the hidden buckle (the movable member 35 latches the receiving part 23) and cannot be easily disassembled.

[0022] Referring to Figure 3, in this embodiment, the base 30 further includes a reset member 33, which normally provides a restoring force so that the movable member 35 has the potential energy to move toward the release position P1. The reset member 33 is, for example, but not limited to, a spring, a leaf spring, a torsion spring, and an elastic element that can generate a restoring force due to deformation. Referring to Figure 3, one end of the reset member 33 is fixed to the base plate 31 through a fixing member 46a, and the other end is fixed to the fixing hole 356 of the movable member 35 through a fixing member 46b. The aforementioned fixing members 46a and 46b are, for example, but not limited to, screws, rivets, or other fixing elements. Taking Figure 4 as an example, when the power connector 10 is plugged into the charging pile assembly, the movable member 35 is driven to slide from the release position P1 to the limit position P2, and the reset member 33 is stretched and deformed. When the power connector 10 is removed from the charging pile assembly, the restoring force of the reset member 33 can push the movable member 35 from the limit position P2 to the release position P1, and the locking part 355 of the movable member 35 moves away from the locking part 23 of the charging base 20.

[0023] Please refer to Figures 3 and 4. In some embodiments, the movable member 35 is a one-piece piece. One end of the base plate 352 extends toward the mounting plate 21 to form a receiving portion 351, and the other end extends toward the mounting plate 21 and bends toward the restrained portion 23 to form a locking portion 355.

[0024] Please refer to Figures 5, 6A, 6B, 7, 8 and 9. Figure 5 shows an exploded view (II) of the base 30 according to another embodiment; Figure 6A shows a partial cross-sectional view of the charging pile according to the other embodiment, showing the movable member 35 in the release position P1; Figure 6B shows a partial cross-sectional view of the charging pile according to the other embodiment, showing the movable member 35 in the limiting position P2; Figure 7 shows an exploded view (III) of the base 30 according to the other embodiment; Figure 8 shows a partial perspective view of the charging pile according to the other embodiment, showing the power connector 10 abutting against the movable member 35, the movable member 35 in the limiting position P2, and the partial base plate 31 and partial charging seat 20 indicated by dashed lines; and Figure 9 shows a partial cross-sectional view at position 9-9 in Figure 8, showing the locking fastener 40 in the limiting segment 350b of the locking hole 350.

[0025] Please refer to Figure 5. In this other embodiment, the movable member 35 is a multi-piece type, including a base plate 352 and a hook plate 354. One end of the hook plate 354 is pivotally connected to one end of the base plate 352, and the other end of the hook plate 354 has a locking part 355. Taking Figure 5 as an example, the hook plate 354 has a pivot plate 357 and a locking part 355. The locking part 355 has a bent section 355a and a pivot section 355b. The two ends of the pivot plate 357 are respectively pivotally connected to the base plate 352 and the pivot section 355b of the locking part 355. The connection between the pivot section 355b and the pivot plate 357 is fixed to the fixing hole 317 of the base plate 31 through the shaft 37. Thereby, when the abutting part 351 of the base plate 352 slides from the release position P1 to the limiting position P2, the locking part 355 rotates correspondingly around the shaft 37.

[0026] For example, please refer to FIG6A. When the movable member 35 is in the release position P1 and the hook plate 354 is in the receiving groove 315, the bent section 355a of the locking part 355 does not lock the locking part 23 of the charging base 20. Please refer to FIG6B. When the power connector 10 is inserted into the insertion groove 310 of the base 30, the power connector 10 abuts against the abutting part 351 of the movable member 35 and drives the hook plate 354 to pivot so that the locking part 355 locks upward (in the +Y direction in the figure) into the locking part 23 of the charging base 20. In other words, when the movable member 35 slides from the release position P1 to the limiting position P2, the base plate 352 slides accordingly along the -Y axis. The base plate 352 causes the locking part 355 of the hook plate 354 to rotate clockwise about the shaft 37 from the perspective of FIG6, so that the bent section 355a can lock into the locking part 23 of the charging base 20.

[0027] Referring to Figure 7, in other embodiments, the base 30 further includes a locking fastener 40, which includes a head 44, a rod 41, a neck 42, and an end 43. The two ends of the rod 41 are the head 44 and the end 43, respectively. The head 44 has a cross or straight geometry to be applied with torque to lock or disengage the locking fastener 40 from the charging pile assembly. The neck 42 is a recess between the rod 41 and the end 43. In some embodiments, the locking fastener 40 is, for example, but not limited to, a screw or anti-theft screw, and the rod 41 has threads. On the other hand, the movable member 35 also includes an extension 358, which protrudes from one side of the base plate 352 toward the mounting plate 21 and passes through the base plate 31 to be located inside the insertion portion 312. The extension 358 has a locking hole 350. Please refer to Figures 7 and 9. The fastener 40 passes through the insertion portion 312a (locking hole 316 in Figure 7) of the charging base 20 and the extension portion 358 (locking hole 350 in Figure 7) of the movable member 35.

[0028] Referring to Figure 8, in other embodiments, the locking hole 350 has a limiting section 350b and an insertion section 350a. The limiting section 350b and the insertion section 350a of the locking hole 350 are connected, and the width of the limiting section 350b is smaller than that of the insertion section 350a. Referring to Figure 9, the width D2 of the neck 42 of the locking fastener 40 corresponds to the width of the limiting section 350b of the locking hole 350, and the width D3 of the end 43 of the locking fastener 40 corresponds to the width of the insertion section 350a of the locking hole 350. Specifically, on the Z-axis, the width D2 of the neck 42 of the locking fastener 40 is smaller than the width D3 of the end 43, and the width D3 of the end 43 of the locking fastener 40 is greater than the width of the limiting section 350b of the locking hole 350. The width D2 of the neck 42 of the locking fastener 40 is substantially equal to or less than the width of the limiting section 350b of the locking hole 350. In some embodiments, the locking hole 350 has a gourd-shaped opening. In this way, the locking device 40 is not easily disengaged from the locking hole 350 during the sliding process of the limiting section 350b of the locking hole 350.

[0029] Additionally, referring to FIG8, in some embodiments, the setting direction of the limiting segment 350b and the insertion segment 350a is substantially parallel to the sliding direction of the movable member 35. For example, when the movable member 35 is in the release position P1, the neck 42 of the locking member 40 is located in the insertion segment 350a of the locking hole 350. At this time, the locking member 40 does not interfere with the sliding of the movable member 35, and the locking member 40 can be operated to disengage from the base plate 31 and the charging base 20. When the movable member 35 slides from the release position P1 toward the limiting position P2, the locking hole 350 of the movable member 35 also moves in the same direction relative to the locking member 40. Thus, when the movable member 35 is in the limiting position P2, the neck 42 of the locking member 40 is also located in the limiting segment 350b of the locking hole 350 (as shown in FIG8), such that the limiting segment 350b limits the locking member 40 to the base plate 31, and the charging base 20 is fixed to the base plate 31. In this way, when the power connector 10 is plugged into the charging pile assembly, not only can the hidden buckle (moving part 35) inside the charging pile assembly be touched, but the locking fastener 40 through the moving part 35 will also be limited and cannot be loosened and removed at will. This makes it impossible for the moving part 35 to be easily released from the limited position P2 and returned to the released position P1. Therefore, the charging pile or charging pile assembly will be more difficult to disassemble and steal.

[0030] The other embodiments shown in Figures 7 to 9 have a mechanism for engaging the locking fastener 40 and the locking hole 350 to form an anti-theft screw structure. This mechanism can be applied not only to the movable member 35 in the embodiments shown in Figures 1 to 4, but also to the embodiments shown in Figures 5 to 6B, to further enhance the anti-theft function of making the charging base 20 less likely to be removed from the base 30. Furthermore, although the movable member 35 of the present invention is described in the above embodiments as being slidably mounted on the base 30, it is not excluded that it can be movably mounted on the base 30 using a lever or pivot mechanism, so that it can be driven to lock the charging base 20 when the power connector 10 is inserted.

[0031] As can be seen from the embodiments in Figures 1 to 4 and Figures 5 to 6B, the present invention first combines the charging base 20 and the base 30, restricting them from arbitrarily separating in the X and Y axis directions. Then, by inserting the power connector 10 to establish an electrical connection, the movable member 35 on the base 30 is activated to lock the charging base 20 in the +Y or -Y direction, thereby further restricting the charging base 20 and the base 30 from arbitrarily separating in the Z axis direction. However, in other embodiments, the direction of the limiting position when the charging base 20 and the base 30 are combined and the direction of the locking of the movable member 35 can be adjusted as needed.

[0032] Furthermore, referring to Figure 10, in other embodiments, the charging device assembly includes a charging base 20 and a base 30. The charging base 20 includes a housing 22 and a movable member 35. The housing 22 has a insertion slot 220, and the insertion slot 220 has a plurality of electrical contacts 25, which correspond to a plurality of electrical terminals 15 of the power connector 10 (the detailed structure is similar to that in Figure 2). The movable member 35 is adapted to be movably disposed on the housing 22, and the movable member 35 is adjacent to the insertion slot 220. The base 30 is adapted to engage with the charging base 20, and when the power connector 10 is inserted into the insertion slot 220, the movable member 35 is adapted to engage the base 30. In other words, the insertion slot 310, originally located on the base 30, is instead located on the charging base 20. The insertion slot 220 of the charging base 20 contains multiple electrical contacts 25. Furthermore, the movable member 35 and related structures and mating elements are changed from being located in the base 30 to being located in the charging base 20. Therefore, the object that the movable member 35 engages changes from the charging base 20 in the previous embodiment to the base 30. Since this embodiment is merely a matter of swapping the position of the movable member 35 and related engaging mechanisms from the base 30 to the charging base 20, the specific details are easily understood by those skilled in the art, and therefore, detailed descriptions and drawings are not elaborated upon here.

[0033] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention.
