DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two, and other quantifiers are similar.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0037] In the related art, charging piles are often placed outdoors. Before and after charging, the charging cable needs to be dragged manually because of the distance limit between the electric vehicle charging port and the charging pile. In the process of manual dragging, not only is it easy to cause wear on the outer wall of the charging cable, but it is also easy to cause abnormal twisting and entanglement of the charging cable due to untimely and inaccurate storage of the charging cable after use, which has an adverse effect on the service life of the charging cable and the reuse of the charging cable. Although relatively complete waterproof measures have been taken during the research and development of the charging pile, the connector of the charging gun on the charging pile is still at risk of being immersed in water stains in heavy rain, causing damage to the interface.

[0038] In view of this, optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0039] In some embodiments, Figure 1 , Figure 2 As shown, an embodiment of the present disclosure provides a charging pile, including: a box body 10, a charging gun 210, a wire twisting device 300 and a storage compartment 101 for accommodating the charging gun 210.

[0040] Specifically, a power cord 200 for providing power to the charging gun 210 is disposed inside the box 10, and a portion of the power cord 200 extends outside the box 10 for connecting to the charging gun 210. The length of the power cord 200 outside the box 10 is long enough to facilitate the user to connect the charging gun 210 to the device to be charged. The wire twisting device 300 is movably disposed on the base plate, and is used to organize and store the power cord 200 outside the box 10, so that the appearance of the box 10 remains neat and tidy, without unnecessary wires, and to avoid accidents such as leakage caused by wire damage.

[0041] In some embodiments, Figure 3 As shown, at least one side surface of the outer portion of the box body 10 is configured as a substrate 100 , and a portion of the substrate 100 is recessed into the inner portion of the box body 10 to form the accommodating chamber 101 for accommodating the charging gun 210 .

[0042] like Figure 4 As shown, the storage bin 101 is equipped with a movable bin door, which can open or close the storage bin 101. The bin door includes: a first bin door 141 and a second bin door 142, which are used to open or close the storage bin 101 to prevent water from entering the storage bin 101 during rainy days.

[0043] After the charging gun 210 is taken out of the storage compartment 101 , in response to the user pulling the power cord 200 , the door of the storage compartment 101 can be closed to prevent rainwater from entering the storage compartment 101 and causing damage to the power equipment or leakage and other accidents.

[0044] In some embodiments, the upper and lower edges of the storage bin 101 are respectively provided with slide rails 102, and the edge of the slide rail 102 extends in the direction of the storage bin 101, and is used to limit the displacement space of the bin door, so that the bin door always moves in the width extension direction of the substrate 100. The length of the slide rail 102 is sufficient for the bin door to switch between the open or closed position.

[0045] In some embodiments, the distance between the two slide rails 102 is greater than the height of the warehouse door, so that the warehouse door can move up and down between the two slide rails 102, and there is redundant space between the warehouse door and the slide rails 102, so that the warehouse door can move in an arc inside the slide rails 102.

[0046] In some embodiments, Figure 4 As shown, a first connecting rod 110 is provided on the first bin door 141, and the first connecting rod 110 is movably connected to the base plate 100 and the first bin door 141, and is used to push the first connecting rod 110 under the transmission of the shifting rod 331 of the stranding device 300 to move the first bin door 141.

[0047] The first connecting rod 110 includes: a first connecting portion 111 and a second connecting portion 112, wherein the first connecting portion 111 is rotatably connected to the base plate 100, and a push portion 113 is provided at one end of the first connecting rod 110 adjacent to the first connecting portion 111; and the second connecting portion 112 is rotatably connected to the first bin door 141. In response to the first connecting rod 110 rotating relative to the base plate 100 based on the first connecting portion 111, the first connecting rod 110 drives the first bin door 141 to rotate based on the second connecting portion 112, so that the first bin door 141 moves in an arc to open or close the containing bin 101.

[0048] In some embodiments, a second connecting rod 120 is disposed on the second compartment door 142. The third connecting portion 121 and the fourth connecting portion 122 of the second connecting rod 120 are rotatably connected to the base plate 100 and the second compartment door 142, respectively. In response to the second connecting rod 120 and the base plate 100 rotating relative to each other based on the third connecting portion 121, the second connecting rod 120 drives the second compartment door 142 to rotate based on the fourth connecting portion 122, so that the second compartment door 142 switches between an open position or a closed position, so as to open or close the containing compartment 101.

[0049] In some embodiments, a third connecting rod 130 may be further provided on the first door 141. The third connecting rod 130 is provided between the first connecting rod 110 and the second connecting rod 120 and is configured as an "L-shaped" structure. The third connecting rod 130 includes: a fifth connecting portion 131 and a sixth connecting portion 132, wherein the fifth connecting portion 131 is rotatably connected to the base plate 100; and the sixth connecting portion 132 is rotatably connected to the first door 141.

[0050] In some embodiments, Figure 5 As shown, the second connecting rod 120 and one end of the second connecting rod 120 adjacent to the third connecting portion 121 are provided with a second meshing portion; the third connecting rod 130 is provided with a third meshing portion at one end adjacent to the fifth connecting portion 131, which is used to mesh with the second meshing portion. In response to the rotation of the first connecting rod 110, the third connecting rod 130 rotates synchronously with the first connecting rod 110, and the third meshing portion meshes with the second meshing portion to drive the second connecting rod 120 to rotate in the opposite direction during the rotation of the third connecting rod 130. The second connecting rod 120 has the same rotation angle and opposite rotation direction as the first connecting rod 110 or the third connecting rod 130, thereby, the second compartment door 142 and the first compartment door 141 move in the opposite direction at the same time. The first compartment door 141 and the second compartment door 142 move simultaneously to close the containing compartment 101.

[0051] The provision of the third connecting rod 130 can reduce the workpiece pressure of the first connecting rod 110 , extend the service life of the first connecting rod 110 , and in practical applications, avoid the first compartment door 141 being unable to open or close normally due to damage to the workpiece of the first connecting rod 110 .

[0052] In some embodiments, Figure 6 As shown, a first connecting rod 110 is provided on the first bin door 141, and the first connecting portion 111 and the second connecting portion 112 of the first connecting rod 110 are rotatably connected to the base plate 100 and the first bin door 141 respectively. In response to the first connecting rod 110 rotating relative to the base plate 100 based on the first connecting portion 111, the first connecting rod 110 drives the first bin door 141 to rotate based on the second connecting portion 112, so that the first bin door 141 switches between an open position or a closed position to open or close the containing bin 101.

[0053] A second connecting rod 120 is provided on the second bin door 142, and the third connecting portion 121 and the fourth connecting portion 122 of the second connecting rod 120 are rotatably connected to the base plate 100 and the second bin door 142 respectively. In response to the second connecting rod 120 rotating relative to the base plate 100 based on the third connecting portion 121, the second connecting rod 120 drives the second bin door 142 to rotate based on the fourth connecting portion 122, so that the second bin door 142 switches between an open position or a closed position to open or close the containing bin 101.

[0054] Furthermore, a portion of the first connecting rod 110 on the periphery of the first connecting portion 111 extends in a direction away from the first compartment door 141 to form a first meshing portion; a portion of the second connecting rod 120 on the periphery of the third connecting portion 121 extends in a direction away from the second compartment door 142 to form a second meshing portion, and the second meshing portion meshes with the first meshing portion.

[0055] When the first connecting rod 110 rotates, the first engaging portion and the second engaging portion engage and rotate, so that the first connecting rod 110 can drive the second connecting rod 120 to rotate. The second connecting rod 120 and the first connecting rod 110 have the same rotation angle and opposite rotation direction, so that the second compartment door 142 and the first compartment door 141 move in opposite directions at the same time. The first compartment door 141 and the second compartment door 142 move at the same time to open or close the containing compartment 101.

[0056] In this embodiment, the first connecting rod 110 is directly engaged with the second connecting rod 120 to realize the opening or closing of the first compartment door 141 and the second compartment door 142. The compartment door closing realized by this embodiment is more convenient, that is, the first compartment door 141 and the second compartment door 142 can be opened or closed without the intervention of the third connecting rod 130, and it has the advantages of simple structure and good mechanical responsiveness.

[0057] In other embodiments, Figure 7 As shown, only one first bin door 141 may be provided on the slide rail 102. The first bin door 141 is provided with a first connecting rod 110, which is connected to the base plate 100 and the first bin door 141 at the same time, and is used to move the first bin door 141 under the transmission of the stranding device 300 to open or close the accommodating bin 101.

[0058] In this embodiment, the first connecting rod 110 is separately provided to realize the opening or closing of the storage bin 101. Compared with the double-bin door structure, the first bin door 141 provided in this embodiment has a longer moving stroke, and the shaft body 310 needs to rotate at a larger angle to switch from the first limit position to the second limit position. The separately provided first bin door 141 has the advantages of simple structure and reduced cost. Figure 8 , Fig. 9 As shown, a wire twisting device 300 is also provided on the substrate 100 , and the wire twisting device 300 includes a shaft 310 , a limiting roller 330 , a ratchet gear 340 , a limiting block 350 , a free roller 360 and a protective shell 370 .

[0059] Specifically, Fig.10 As shown, the shaft body 310 is connected to the limiting roller 330, and the shaft body 310 is detachably connected to the ratchet gear 340. The limiting roller 330 and the ratchet gear 340 rotate synchronously with the rotation of the shaft body 310. A ratchet is provided on the surface of the limiting block 350, and the ratchet engages with the gear teeth of the ratchet gear 340 to limit the rotation direction and spatial position of the ratchet gear 340. The free roller 360 is rotatably sleeved on the shaft body 310 and is located between the limiting roller 330 and the ratchet gear 340. The protective shell 370 is used to protect the shaft body 310, the limiting roller 330, the ratchet gear 340, the limiting block 350 and the free roller 360 to ensure that the interior of the wire twisting device 300 is protected from external damage.

[0060] In some embodiments, the shaft 310 is movably connected to the substrate 100 and has a first end 311 and a second end 312. Fig.11As shown, the first end 311 is rotatably connected to the box body 10 , and a limiting groove 301 is provided at the end of the first end 311 .

[0061] The shaft body 310 is provided with a shaft core 313, and the shaft core 313 is rotatably connected to the inside of the box body 10. The first end 311 is in contact with the substrate 100, and the first end 311 is provided with a limiting groove 301 facing the end face of the substrate 100, and the limiting groove 301 of the first end 311 can be a fan-shaped recessed structure. A limiting portion is provided on the base surface where the substrate contacts the first end 311, and the limiting portion can be matched with the limiting groove 301 and can be a fan-shaped protrusion structure, and the fan-shaped protrusion area of ​​the limiting portion is smaller than the fan-shaped recessed area of ​​the limiting groove 301, so that the shaft body 310 can rotate relative to the base surface. The rotation angle of the shaft body 310 is a preset value. Thus, when the shaft body 310 rotates, the fan-shaped protrusion can be used to limit the fan-shaped recess during the rotation of the shaft body 310.

[0062] Preferably, in order to ensure the balanced rotation of the shaft body 310, the first end 311 may be provided with a plurality of fan-shaped recesses, and correspondingly, the base plate 100 is provided with a corresponding number of fan-shaped protrusions as the fan-shaped recesses. When the shaft body 310 rotates in its own axial extension direction, the fan-shaped protrusions limit the rotation of the fan-shaped recesses.

[0063] It should be separately explained that the present disclosure does not limit the shape of the limit groove 301. The shape of the limit groove 301 can be a fan shape, an arc shape, or any other shape that can have a limiting effect on the shaft body 310. The limiting portion matches the shape of the limit groove 301 and is used to limit the rotation angle of the shaft body 310.

[0064] The shaft body 310 has a first limit position before the rotation and a second limit position after the rotation when rotating, in response to the user not pulling the power cord 200. When the charging gun 210 is in the accommodating cavity 101, the power cord 200 is wound around the free roller 330, and the shaft body 310 is in the first limit position; in response to the user taking out the charging gun 210 from the accommodating cavity 101 and pulling the power cord 200 to the extreme position of the shaft body 310, the shaft body 310 is in the second limit position.

[0065] In some embodiments, the second end 312 of the shaft body 310 is disposed at an end of the shaft body 310 away from the box body 10 , and an installation groove 302 is disposed at the end of the second end 312 , and the installation groove 302 passes through the center of the shaft body 310 , and the installation groove 302 is used to install the first elastic member 320 .

[0066] In some embodiments, Fig.10 As shown, the first elastic member 320 may be a coil spring, and the two ends of the coil spring are respectively a fixed end and a spring clip, the fixed end of the coil spring is arranged in the mounting groove 302 of the second end 312 of the shaft body 310, and the spring clip is connected to the inner side wall of the free roller 360. The first elastic member 320 is used to assist the free roller 360 in resetting.

[0067] In some embodiments, the limiting roller 330 is movably disposed on the base plate 100, and the limiting roller 330 is connected to and rotates synchronously with the shaft 310. When the power cord 200 is unwound by the wire twisting device 300, the shaft 310 is driven to rotate clockwise, and at this time, the limiting roller 330 rotates synchronously with the shaft 310.

[0068] In some embodiments, a lever 331 is provided on one side of the limiting roller 330 adjacent to the first connecting rod 110 , and the lever 331 is used to move the pushing portion 113 of the first connecting rod 110 to open or close the warehouse door through the rotation of the first connecting rod 110 .

[0069] Specifically, one end of the lever 331 away from the limiting roller 330 is provided with an end of a pushing portion which contacts the pushing portion 113 , and a thrust is applied to the first connecting rod 110 through the pushing portion 113 to drive the compartment door to move.

[0070] In some embodiments, Figure 4 As shown, during the clockwise rotation of the limiting roller 330, the lever 331 contacts and pushes against the pushing portion 113. In response to the clockwise rotation of the lever 331, the first connecting rod 110 rotates counterclockwise relative to the base plate 100 based on the first connecting portion 111, and the third connecting rod 130 rotates synchronously and in the same direction as the first connecting rod 110. Since the third meshing portion meshes and rotates with the second meshing portion, the third connecting rod 130 can drive the second connecting rod 120 to rotate. The second connecting rod 120 has the same rotation angle and opposite rotation direction as the first connecting rod 110 or the third connecting rod 130, thereby, the second compartment door 142 and the first compartment door 141 move in opposite directions at the same time. So that the first compartment door 141 and the second compartment door 142 are switched from the open position to the closed position, the first compartment door 141 and the second compartment door 142 move simultaneously to close the accommodating compartment 101. The accommodating compartment 101 is in a closed state, as shown in FIG. Figure 5 shown.

[0071] In some embodiments, the rotation angle of the shaft 311 from the first limited position to the second limited position is α°. In response to the rotation of the shaft 311, the lever 331 of the limiting roller 330 is driven to push against the first connecting rod 110 to move the first compartment door 141. The rotation angle of the first connecting rod 110 is β°, wherein α≤β, so that the engagement between the ratchet gear 340 and the limiting block 350 is more accurate; the maximum moving distance of the first compartment door 141 is L.

[0072] Specifically, when the shaft 311 rotates α°, the first connecting rod 110 rotates β°, the first door 141 moves L, and correspondingly, the second door 142 has the same displacement length as the first door 141. If the width of the storage chamber 101 is K, 2L≥K, so that the storage chamber 101 is closed.

[0073] In some embodiments, the free roller 360 is rotatably mounted on the shaft 310 and is located between the limit roller 330 and the ratchet gear 340. The power cord 200 is used to be wound around the free roller 360. When the user pulls the power cord 200, the free roller 360 rotates in a clockwise direction. The rotating free roller 360 can drive the limit roller 330 to rotate in the same direction. When the shaft 310 rotates from the first limit position to the second limit position under the rotation of the free roller 360, when the power cord 200 continues to be pulled, the limit roller 330 no longer rotates, but at this time the free roller 360 can still rotate freely as the power cord 200 is pulled, so that the free roller 360 rotates from the original position toward the rotated position.

[0074] The first elastic member 320 disposed inside the free roller 360 always rotates the free roller 360 from the rotation position toward the original position. When the length of the power cord 200 pulled out by the user exceeds the usable length, the excess power cord 200 will be switched from the rotation position to the original position under the action of the first elastic member 320. At this time, the excess power cord 200 is automatically rolled into the free roller 360.

[0075] In some embodiments, Fig.12As shown, the wire twisting device 300 also includes: a ratchet gear 340 and a limit block 350. The ratchet gear 340 is connected to the shaft body 310 and rotates synchronously. The edge of the ratchet gear 340 has a plurality of ratchet teeth, and the ratchet teeth have a long tooth side and a short tooth side. The surface of the limit block 350 is provided with a plurality of pawls, and the pawls mesh with the ratchet teeth. In response to the shaft body 310 switching from the first limit position to the second limit position, the surface of the limit block 350 is provided with a pawl, and the ratchet teeth mesh with the pawls, and the ratchet teeth are pushed by the pawls to perform stepping motion. The characteristic of this meshing motion is that the ratchet can only rotate in one direction and cannot be reversed, thereby limiting the rotation direction of the ratchet gear 340. The ratchet mechanism has the advantages of simple structure, convenient manufacturing, and reliable operation.

[0076] In some embodiments, a second elastic member 351 is provided on one side of the limit block 350 adjacent to the ratchet gear 340, and both ends of the second elastic member 351 are respectively connected to the first side of the limit block 350 and the inner wall of the protective shell 370, so as to make the limit block 350 tend to approach the other end of the second elastic member 351, so that the pawl and the ratchet wheel remain in contact, so as to assist the limit block 350 to engage with the ratchet gear 340 to limit the ratchet gear 340.

[0077] In some embodiments, a third elastic member 352 is provided on one side of the limit block 350 away from the second elastic member 351, and both ends of the third elastic member 352 are respectively connected to the limit block 350 and the protective housing 370, so as to make the protective block 350 have a tendency to move toward the inside of the wire twisting device 300. After the limit block 350 is pulled by the user, it is disengaged from the ratchet gear 340, and the ratchet gear 340 is reset. When the user cancels the pulling force applied to the limit block 350, the third elastic member 352 can reset the limit block 350 to re-engage with the ratchet gear 340.

[0078] In some embodiments, the protective shell 370 is disposed outside the limiting roller to protect the stranding device 300 .

[0079] The side wall of the protective shell 370 is provided with at least one opening 303, and at least a part of the limit block 350 extends out of the protective shell 370 from the opening 303 and can move within the range limited by the opening 303. The user can pull the limit block 350 to disengage the limit block 350 from the ratchet gear 340, thereby causing the power cord 200 to be wound into the wire twisting device 300.

[0080] When charging is finished, the user can manually pull the limit block 350 to disengage the limit block 350 from the ratchet gear 340. Further, when the free roller 360 is reset under the action of the first elastic member 320, the shaft 310, the limit roller 330 and the ratchet gear 340 are reset from the second limited position to the first limited position. At this time, the power cord 200 is stored by the wire twisting device 300 under the reset action of the free roller 360. At this time, the limit block 350 is released, the limit block 350 is engaged with the ratchet gear 340, and the door of the storage bin 101 is opened, so that the charging gun 210 can be placed in the storage bin 101.

[0081] In some embodiments, the side wall of the protective housing 370 is provided with at least one slot, and the slot is used to assist the power cord 200 to be rolled into and / or out of the wire twisting device 300 .

[0082] Specifically, the slots of the protective housing 370 of the wire twisting device 300 are used for winding in and / or unwinding the power cord 200. Auxiliary rollers 371 may be provided on both sides of the open mouth 303, respectively. When the power cord 200 is wound in and / or unwound from the wire twisting device 300, the auxiliary rollers 371 are used to assist the power cord 200 in winding in and / or unwinding, reduce the resistance of the power cord 200 when winding in and / or unwinding, and make it easier for the user to pull out or retract the power cord 200.

[0083] In some embodiments, the charging pile also includes: a heat dissipation outlet 20 and a touch screen 50, the heat dissipation outlet 20 and the touch screen 50 are arranged on the side wall of the box 10 or the substrate 100, and a lighting assembly 40 is installed on the top of the substrate 100 to facilitate users to use the charging pile at night.

[0084] A solar panel 30 may also be provided on the top of the box 10 to convert solar energy into electrical energy and store it to power the charging pile.

[0085] In some embodiments, the box body 10 may be provided with two substrates 100, such as Figure 1 , Figure 2 As shown, the substrates 100 are respectively arranged on both sides of the box body 10, and the two substrates 100 are respectively provided with a twisting device 300 and a receiving chamber 101. The bottom of the twisting device 300 is connected to the receiving chamber 101 for receiving the charging gun 210, and the charging gun 210 is connected to the power cord 200.

[0086] The working principle of the wire twisting device 300 is as follows: when the user uses the charging gun 210 to charge, the power cord 200 will be pulled to make the power cord 200 unrolled by the wire twisting device 300. During the unrolling process of the power cord 200, the free roller 360 will be driven to roll clockwise. During the rolling process, the free roller 360 will drive the shaft body 310 to rotate in the same direction. Since a limiting groove 301 is provided on the side where the shaft body 310 is connected to the box body 10, the limiting groove 301 can be a fan-shaped groove, or any other groove that can limit the rotation of the shaft body 310. The ratchet gear 340 rotates synchronously with the shaft body 310, and can only rotate from the first limiting position to the second limiting position. The teeth of the ratchet gear 340 are engaged with the pawl of the limiting block 350, and step motion is performed under the push of the pawl.

[0087] In response to the power cord 200 being rolled out, the shaft 310 rotates from the first limit position to the second limit position, and the pawl stops against the ratchet teeth, so that the ratchet gear 340 remains in the second limit position. At this time, the free roller 360 can rotate freely as the power cord 200 is rolled out, and the user can pull out the power cord 200 as needed. When the user pulls the power cord 200 out, the free roller 360 moves from the original position to the rotation position.

[0088] At this time, the lever 331 pushes against the pushing portion 113 of the first connecting rod 110 to move the first connecting rod 110. In response to the first connecting rod 110 rotating relative to the base plate 100 based on the first connecting portion 111, the first connecting rod 110 drives the first bin door 141 to rotate based on the second connecting portion 112, so that the first bin door 141 switches between an open position and a closed position, so as to open or close the containing bin 101.

[0089] When charging is finished, the user can manually pull the limit block 350 in a direction away from the wire twisting device 300 to disengage the limit block 350 from the ratchet gear 340. Further, when the free roller 360 is reset under the action of the first elastic member 320, the shaft 310, the limit roller 330 and the ratchet gear 340 are reset from the second limited position to the first limited position, the limit block 350 is engaged with the ratchet gear 340, and the power cord 200 is stored by the wire twisting device 300 under the reset action of the automatic roller. The door of the storage compartment 101 is opened, so that the charging gun 210 is just placed in the storage compartment 101.
