Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging technology, specifically to a charging pile. Background Technology
[0002] With the increasing popularity of new energy vehicles, charging stations, as important energy replenishment facilities, are widely distributed in various locations such as residential communities, shopping mall parking lots, and highway service areas. In actual use, charging stations need to be connected to new energy vehicles via cables and charging guns connected to the ends of the cables to achieve charging. To facilitate user operation and ensure the cleanliness of the equipment, charging stations are usually equipped with a cable retraction mechanism, which is used to retract the cable after charging is completed and extend the cable when charging is needed.
[0003] Currently, most charging stations on the market use a single motor to drive the cable winding and unwinding mechanism. This means that a single motor drives a turntable to rotate, and the rotation of the turntable is used to wind up or unwind the cable.
[0004] However, during the cable deployment and retraction process, the cable tension often becomes low. For example, when the cable near the outlet is lifted, the tension generated by the cable's own weight is greatly reduced. When the cable tension is low, the portion of the cable wound on the turntable becomes loose, preventing it from being tightly wound. In this situation, the loose cable occupies more space, causing interference and friction between the cable and the inner wall of the charging station. Consequently, the cable may not move according to the originally set tension and direction during the next deployment, leading to cable jamming. Furthermore, the loose cable occupies more space, making it impossible for the limited space inside the charging station to fully accommodate the cable. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this application provides a charging pile. A first motor drives a turntable to rotate, and a second motor drives a cable drive unit to rotate. The first and second motors drive the cable to move, enabling cable winding or unwinding. During the winding or unwinding process, the tension of the portion of the cable about to be wound on the turntable is adjusted to a suitable tension range, ensuring the cable is tightly wound on the turntable and preventing the wound portion of the cable from becoming loose. This avoids problems such as cable jamming or the charging pile not being able to fully accommodate the cable.

[0038] This application provides a charging pile, in which a first motor drives a turntable to rotate and a second motor drives a cable drive unit to rotate. The first and second motors drive the cable to move to achieve cable winding or unwinding. During the winding or unwinding process, the tension of the portion of the cable about to be wound on the turntable is adjusted to a suitable tension range, so that the cable can be tightly wound on the turntable, preventing the wound portion of the cable on the turntable from becoming loose, thereby avoiding problems such as cable jamming or the charging pile not being able to fully accommodate the cable.
[0039] The charging pile provided in this application will be described in detail below with reference to the accompanying drawings.
[0040] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the charging pile provided in this application. Figure 1As shown, this application provides a charging pile 1, which includes a housing K and a first mounting part B. The first mounting part B is used to fix the charging pile 1 in an installation position. The first mounting part B is a mounting bracket.
[0041] Please see Figure 2 , Figure 2 This is a schematic diagram of the overall structure of the second embodiment of the charging pile provided in this application. (See attached diagram.)

The cable L is connected to the end of the charging gun 20. The temperature detection device is used to detect the temperature inside the charging station 1, and the temperature regulating device 90 is used to heat and / or dissipate heat from the cable L. In this way, if the temperature of the cable L is too high or / or too low, the temperature of the cable L can be adjusted to a suitable temperature range, thereby facilitating cable winding or unwinding.
[0043] Please see Figure 5 , Figure 5 This is a three-dimensional schematic diagram of the internal structure of the charging pile provided in the embodiments of this application. For example... Figure 5 As shown, in some embodiments, the charging pile 1 further includes a control module 10, which controls the temperature regulating device 90 to operate according to the temperature detected by the temperature detection device in the charging pile 1, so as to heat and / or dissipate heat from the cable L.

[0059] Optionally, the heating wires 911 are arranged to form corresponding heating areas.
[0060] Optionally, the heating film can directly form the corresponding heating area.
[0061] like Figure 3 As shown, in some embodiments, the charging pile 1 further includes a turntable drive device 70. The turntable drive device 70 includes a turntable gear 71 and a turntable drive gear 72, the turntable drive gear 72 meshing with the turntable gear 71, and the turntable gear 71 driving the turntable 50 to rotate. The output shaft of the first motor 30 is connected to the turntable drive gear 72, and the first motor 30 controls the rotation of the turntable drive gear 72 to drive the turntable 50 to rotate.
[0062] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of the first embodiment of the turntable provided in this application. Figure 6As shown, in some embodiments, the turntable 50 includes a turntable base 51 and a turntable spindle 52, and the first end of the cable L is connected to the turntable spindle 52 or has been wound on the turntable spindle 52.
[0063] Optionally, the turntable 50 and the turntable gear 71 are integrally formed or fixedly connected.
[0064] Optionally, the diameter of the turntable base 51 is larger than the diameter of the turntable shaft 52, and the diameter of the turntable gear 71 is larger than the diameter of the turntable shaft 52, forming a cable storage space between the turntable base 51 and the turntable gear 71. In this way, a portion of the cable L1 that is about to be wound onto the turntable 50 can be confined within the cable storage space, making it easier to neatly wind this portion of cable L1 onto the turntable shaft 52, thereby ensuring that all the wound cable L is located within the cable storage space.
[0065] Please see Figure 7 , Figure 7 This is a rear view schematic diagram of part of the internal structure of the charging pile provided in the embodiments of this application. For example... Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, the temperature regulating device 90 includes a heating device 91, and the charging pile 1 also includes a turntable 50, with the cable L wound around the turntable 50.
[0066] like Figure 3 As shown, in some embodiments, the heating device 91 is disposed opposite to the turntable 50. The heating device 91 is not directly disposed on the turntable 50. In this case, the heating device 91 heats the cable L by heating the air in the charging pile 1. The heating device 91 does not directly contact the cable L wound on the turntable 50, which can avoid overheating of the cable L and improve the uniformity of heating.
[0067] In some embodiments, the heating area of the heating device 91 is not less than the area of the turntable shaft center portion 52 of the turntable 50. The heating area of the heating device 91 refers to the area inside the boundary line of the area where the heating wires 911 are arranged or the area of the heating film. In this way, the heating speed of the cable L wound on the turntable shaft center portion 52 by the heating device 91 can be increased.
[0068] In some embodiments, the heating device 91 is mounted on a turntable holder 82 opposite to the side of the turntable gear 71 away from the cable L. In this way, the heating device 91 does not directly contact the cable L wound on the turntable 50, which avoids overheating of the cable L and improves the uniformity of heating.
[0069] Optionally, the heating device 91 is located in the area opposite to the cable L wound on the turntable 50. For example, the heating device 91 is located on the side of the turntable base 51 away from the cable L. In this way, the heating device 91 is closer to the cable L, which can speed up the heating process, and it does not directly contact the cable L wound on the turntable 50, thus avoiding overheating of the cable L.
[0070] like Figure 3 and Figure 4 As shown, in some embodiments, a grid 711 is provided on the turntable gear 71, and the heating device 91 is opposite to the grid 711 of the turntable gear 71. In this way, overheating of the turntable gear 71 can be avoided, and the uniformity of heating can be improved.
[0071] like Figure 7 As shown, in some embodiments, the turntable base 51 is provided with a perforated portion 511. In this way, overheating of the cable L can be avoided.
[0072] In some embodiments, the turntable gear 71 is provided with a perforated grid, which is opposite to the perforated portion 511 of the turntable base 51. In this way, overheating of the turntable gear 71 and the cable L can be avoided, and the air circulation in the cable storage space can be improved, thereby improving the uniformity of heating.
[0073] In some embodiments, the heating device 91 is disposed on the turntable mounting backplate 81 opposite to the side of the turntable base 51 away from the cable L. In this way, the heating device 91 does not directly contact the cable L wound on the turntable 50, which can avoid overheating of the cable L and improve the uniformity of heating.
[0074] In some embodiments, the temperature regulating device 90 includes a heat dissipation device, which includes at least one of a heat sink, a semiconductor cooling device, and a liquid cooling device.
[0075] In some embodiments, the heat dissipation device is disposed opposite to the turntable 50. The heat dissipation device is not directly disposed on the turntable 50.
[0076] In some embodiments, a heat dissipation device is provided on a turntable mounting bracket 82 opposite to the side of the turntable gear 71 away from the cable L.
[0077] In some embodiments, a heat dissipation device is disposed on a turntable mounting backplate 81 opposite to the side of the turntable chassis 51 away from the cable L.
[0078] In some embodiments, the charging pile 1 also includes a control module 10, and a heat dissipation device is also used to dissipate heat from the control module 10.
[0079] For example, the heat dissipation device includes a heat sink.
[0080] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, the temperature regulating device 90 further includes a fan 93, and the number of fans 93 is at least one. The fan 93 is used to blow air onto the cable L.
[0081] In some embodiments, when the heating device 91 is working, the fan 93 is also working. The fan 93 can blow the heated air to make the air temperature in the charging pile 1 uniform, so that the heating device 91 can heat the cable L uniformly.
[0082] In some implementations, when the temperature detection device detects that the temperature inside the charging pile 1 is lower than a first preset temperature, the control module 10 can control the heating module to heat the cable L to soften the cable L and facilitate cable laying. At the same time, it can also control the fan 93 to blow air.
[0083] For example, the first preset temperature is -10 degrees, -20 degrees, -30 degrees or -35 degrees, etc.
[0084] In some implementations, the fan 93 also operates when the heat dissipation device is working, in order to dissipate heat evenly on the cable L and accelerate the heat dissipation speed.
[0085] In some implementations, when neither the heating device 91 nor the heat dissipation device is working, the fan 93 can operate independently to dissipate heat from the cable L.
[0086] In some embodiments, when the temperature detection device detects that the temperature inside the charging pile 1 is higher than a second preset temperature, the control module 10 can control the heat dissipation device to work and / or control the fan 93 to blow air to dissipate heat from the charging pile 1. The second preset temperature is higher than the first preset temperature.
[0087] For example, the second preset temperature is 30 degrees, 35 degrees, 40 degrees or 45 degrees, etc.
[0088] In some embodiments, the fan 93 is also used to blow air onto the control module 10 to dissipate heat from the control module 10.
[0089] As mentioned above, the heat dissipation device is also used to dissipate heat from the control module 10. For example... Figure 5 As shown, for example, the heat sink and the third fan 933 are disposed on the back of the control module 10, and both the heat sink and the third fan 933 are used to dissipate heat from the control module 10.
[0090] Optionally, the blowing angle of the fan 93 can be variable. For example, the fan 93 may include an adjustable-angle blower head.
[0091] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, the charging pile 1 also includes a turntable 50, and the number of fans 93 is multiple, with the multiple fans 93 arranged around the turntable 50.
[0092] Optionally, the fan 93 can be installed at one corner of the charging pile 1. Multiple fans 93 can be installed at multiple corners of the charging pile 1. For example, multiple fans 93 can be installed at the first, second, third, and fourth corners of the charging pile 1, where the first, second, third, and fourth corners are different from each other. In this way, the uniformity of the air temperature within the charging pile 1 can be improved, thereby providing uniform heating or cooling to the cable L.
[0093] For example, there are two fans 93, with the first fan 931 and the second fan 932 arranged around the turntable 50. The first fan 931 is located at the first corner of the charging pile 1, and the second fan 932 is located at the second corner of the charging pile 1.
[0094] Optionally, when there are multiple fans 93, the blowing angles of the multiple fans 93 are different.
[0095] For example, the first fan 931 and the second fan 932 have different blowing angles.
[0096] In some embodiments, the fan 93 includes a heating element and / or a cooling element, the heating element being used to blow hot air from the fan 93 and the cooling element being used to blow cold air from the fan 93.
[0097] In some implementations, the heating and cooling components may both be deactivated, and the fan 93 may only blow air.
[0098] Please see Figure 8 , Figure 8 This is a schematic diagram of the second embodiment of the turntable provided in this application. (See attached diagram.) Figure 8 As shown, in some embodiments, the turntable 50 and the turntable gear 71 are integrally formed. The turntable 50 can be made of... Figure 4 The grille 711 is formed directly in the middle.
[0099] like Figure 5 As shown, in some embodiments, the charging pile 1 also includes a cable drive assembly 60. See also... Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the cable drive assembly provided in an embodiment of this application. Figure 10 This is an exploded structural diagram of the cable drive assembly provided in an embodiment of this application. Figure 9As shown, the ends of both cable L and charging gun 20 pass through cable drive assembly 60. Figure 10 As shown, in some embodiments, the cable drive assembly 60 includes a cable drive portion 61 and a charging gun receiving portion 62. The charging gun receiving portion 62 is used to receive the charging gun 20.
[0100] In some embodiments, the charging station 1 further includes a first motor 30, a second motor 40, a turntable 50, and a charging gun 20. A cable L is wound around the turntable 50 and passes through a cable drive unit 61. The end of the charging gun 20 is connected to the cable L. The first motor 30 drives the turntable 50 to rotate, and the second motor 40 drives the cable drive unit 61 to rotate. The first motor 30 and the second motor 40 are used to gradually retract or extend the cable L into or out of the charging station 1, thereby retracting or extending the charging gun 20.
[0101] For example, the first end of cable L is connected to or wound around turntable 50, and the second end of cable L is connected to the end of charging gun 20. Cable L passes through cable drive assembly 60.
[0102] For the portion of cable L1 that is about to be wound on the turntable 50, the cable drive unit 61 can generate frictional force on the end of this portion of cable L1. At the same time, the rotation of the turntable 50 can generate tension on this portion of cable L1. Through the combined action of the frictional force generated by the cable drive unit 61 and the tension generated by the rotation of the turntable 50, the tension of the portion of cable L1 that is about to be wound on the turntable 50 can be adjusted to a suitable tension range, so that the cable L can be tightly wound on the turntable 50, preventing the wound portion of the cable L on the turntable 50 from becoming loose, thereby avoiding the problem of the cable L getting tangled or knotted together or the charging pile 1 not being able to fully accommodate the cable L.
[0103] By controlling the rotation speed of the turntable 50 and the rotation speed of the cable drive unit 61, the tension generated by the turntable 50 on the portion of cable L1 that is about to be wound on the turntable 50 and the friction generated by the cable drive unit 61 on the end of this portion of cable L1 when the turntable 50 rotates can be controlled, thereby adjusting the tension of the portion of cable L1 that is about to be wound on the turntable 50 to a suitable tension range.
[0104] In some implementations, the control module 10 is used to control the operation of the first motor 30 and the second motor 40.
[0105] In some embodiments, the output shaft of the first motor 30 is connected to the turntable 50. In this way, the first motor 30 can directly drive the turntable 50 to rotate.
[0106] like Figure 3As shown, in some embodiments, the charging pile 1 further includes a turntable drive device 70. The turntable drive device 70 includes a turntable gear 71 and a turntable drive gear 72, the turntable drive gear 72 meshing with the turntable gear 71, and the turntable gear 71 driving the turntable 50 to rotate. The output shaft of the first motor 30 is connected to the turntable drive gear 72, and the first motor 30 controls the rotation of the turntable drive gear 72 to drive the turntable 50 to rotate.
[0107] In some embodiments, the cable drive unit 61 includes a limiting groove 620 for restricting the cable L from disengaging from the cable channel P, the shape of the limiting groove 620 being adapted to the shape of the cable L.
[0108] For example, when the cross-section of the cable L is circular, the shape of the limiting groove 620 is curved.
[0109] Optionally, the cable drive unit 61 also includes a cable limiting unit 630.
[0110] In some embodiments, at least one cable limiting part 630 is provided on at least one side of the cable channel P to limit the swing of the cable L. In this way, the cable L can be kept moving in a predetermined direction of motion without swinging during the cable winding or unwinding process, so that the charging pile 1 can smoothly wind up or unwind the cable.
[0111] Furthermore, in the prior art, the cable L is prone to swaying, which can prevent it from winding neatly on the turntable 50. Excessive swaying or excessive amplitude of the cable L can also damage it. By providing at least one cable limiting part 630 on at least one side of the cable channel P to limit the swaying of the cable L, the number of swaying events and the amplitude of swaying can be reduced, thereby extending the service life of the cable L. Simultaneously, it prevents the cable L from detaching from the cable channel P, reduces the amplitude of swaying, stabilizes the load on the cable drive gear 611, protects the second motor 40 and the cable drive gear 611, and saves energy.
[0112] Optionally, cable limiting portions 630 are provided on at least two sides of the cable channel P, wherein at least one cable limiting portion 630 is provided on each side of the cable channel P. For example, the cable limiting portion 630 includes a first cable limiting portion 631, a second cable limiting portion 632, and a third cable limiting portion 633.
[0113] In some embodiments, the cable limiting part 630 includes a limiting rod that can roll along the take-up direction V3 or the release direction of the cable L. Specifically, when the cable L touches the limiting rod during movement, friction is generated between the cable L and the limiting rod, causing the limiting rod to roll. At the same time, the limiting rod can restrict the swinging of the cable L. In this way, while restricting the swinging of the cable L, excessive friction is not generated on the cable L, and the cable L is not hindered from continuing to move along the take-up direction V3 or the release direction, thereby not affecting the speed of the cable L during the take-up or release process.
[0114] Alternatively, the limiting rod can be a rolling structure such as a roller.
[0115] Optionally, the cable limiting part 630 also includes a fixed shaft passing through the center of the limiting rod.
[0116] In some embodiments, the cable drive unit 61 includes a cable drive gear 611, which includes a limiting groove 620. The cable drive gear 611 is connected to and driven by the second motor 40 to rotate.
[0117] In some embodiments, the cable drive unit 61 includes two sets of cable drive gear sets 610 and a cable channel P formed by the two sets of cable drive gear sets 610. The cable L is accommodated in the cable channel P and can be released or retracted from the charging pile 1 through the cable channel P. The two sets of cable drive gear sets 610 are symmetrically arranged on both sides of the cable channel P. Each set of cable drive gear sets 610 includes at least one cable drive gear 611, and the cable drive gear 611 in each set of cable drive gear sets 610 is in contact with the cable L.
[0118] like Figure 10 As shown, exemplarily, each set of cable-driven gears 610 includes a cable-driven gear 611.
[0119] Optionally, the distance between the two opposing cable drive gears 611 is less than the diameter of the cable L, so that the cable drive gears 611 exert pressure on the cable L, and when the cable drive gears 611 rotate relative to the cable L, they can generate a frictional force on the cable L along the take-up direction V3 or the release direction, which can drive the cable L to move along the take-up direction V3 or the release direction.
[0120] In some embodiments, the cable drive unit 61 further includes a cable limiting rod, which includes a limiting groove 620. The cable limiting rod is not connected to the output end of the motor, and it can roll when the cable L contacts it.
[0121] In some embodiments, at least one cable limiting portion 630 is provided on the first side of the cable channel P, and at least one cable limiting portion 630 is provided on the second side of the cable channel P, with the first side and the second side opposite to each other. For example, a first cable limiting portion 631 is provided on the first side of the cable channel P, and a second cable limiting portion 632 is provided on the second side of the cable channel P, with the first side and the second side opposite to each other. In this way, it is possible to at least restrict the movement or swinging of the cable L in one direction.
[0122] In some embodiments, the distance between the cable limiting part 630 located on the first side of the cable channel P and the cable limiting part 630 located on the second side of the cable channel P is greater than the diameter of the cable L and less than the distance between the turntable base 51 and the turntable gear 71. In this way, when the cable L moves along the take-up direction V3 or the release direction, the cable limiting part 630 does not exert pressure on the cable L, and therefore does not generate friction on the cable L. Friction is only generated when the cable L contacts the cable limiting part 630 due to swinging, thus not hindering the movement of the cable L along the take-up direction V3 or the release direction, and not affecting the speed of the cable L during the take-up or release process. Furthermore, the cable L can be confined between the turntable base 51 and the turntable gear 71.
[0123] In some embodiments, multiple cable limiting parts 630 are disposed on the same side of the cable channel P, and the multiple cable limiting parts 630 are arranged in a straight line along the take-up direction V3 of the cable L. In this way, the swing of the cable L can be further limited.
[0124] like Figure 10 As shown, by way of example, the first cable limiting part 631 and the third cable limiting part 633 are disposed on the same side of the cable channel P, and the first cable limiting part 631 and the third cable limiting part 633 are arranged in a straight line along the cable take-up direction V3 of the cable L.
[0125] For example, there are three cable limiting parts 630, one of which is located on one side of the cable L, and the other two are located on the other side of the cable L.
[0126] In some embodiments, the limiting groove 620 is used to limit the movement of the cable L in a first direction V1, and the cable limiting portion 630 is used to limit the movement of the cable L in a second direction V2, where the first direction V1 is different from the second direction V2. In this way, the movement of the cable L in two different directions can be limited, thereby further limiting the swing of the cable L.
[0127] Optionally, the limiting groove 620 is also used to compress the cable L, so that the cable drive gear 611 can exert pressure on the cable L.
[0128] In some implementations, the first direction V1 is perpendicular to the second direction V2.
[0129] In some embodiments, the charging gun receiving portion 62 includes a first cover plate 621 and a second cover plate 622.
[0130] Please see Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the structure of the first cover plate of the charging gun receiving portion provided in an embodiment of this application. Figure 12 This is a schematic diagram of the structure of the second cover plate of the charging gun receiving portion provided in an embodiment of this application. Figure 11 As shown, the first cover plate 621 includes a first recess 6211. (As indicated...) Figure 12 As shown, the second cover plate 622 includes a second recess 6221. When the first cover plate 621 and the second cover plate 622 are fitted together, the first recess 6211 and the second recess 6221 form a receiving channel for the charging gun 20 to retract or extend. The shapes of the first recess 6211 and the second recess 6221 are adapted to the shape of at least a portion of the charging gun 20. For example, the shapes of the first recess 6211 and the second recess 6221 are adapted to the shape of the end of the charging gun 20. In this way, the charging gun receiving portion 62 can securely house at least a portion of the charging gun 20.
[0131] In some embodiments, the cable limiting part 630 further includes a bearing, and a bearing fixing plate is provided on both the first cover plate 621 and the second cover plate 622. The bearing fixing plate is used to fix the bearing on the first cover plate 621 or the second cover plate 622, and the bearing is fitted onto the limiting rod. In this way, the resistance to the rolling of the limiting rod can be reduced.
[0132] like Figure 10 As shown, in some embodiments, the charging pile 1 further includes a charging gun detection device C. The charging gun detection device C is installed in the charging gun receiving portion 62. The charging gun detection device C includes at least two pairs of photoelectric sensors G, wherein one photoelectric sensor G in each pair is installed on one side of the receiving channel, and the other photoelectric sensor G is installed on the other side of the receiving channel.
[0133] Optionally, the charging gun detection device C includes only two pairs of photoelectric sensors G.
[0134] For example, the charging gun detection device C includes four pairs of photoelectric sensors G. Specifically, the first photoelectric sensor G1 and the second photoelectric sensor G2 constitute the first pair of photoelectric sensors G; the third photoelectric sensor G3 and the fourth photoelectric sensor G4 constitute the second pair of photoelectric sensors G; the fifth photoelectric sensor G5 and the sixth photoelectric sensor G6 constitute the third pair of photoelectric sensors G; and the seventh photoelectric sensor G7 and the eighth photoelectric sensor G8 constitute the fourth pair of photoelectric sensors G.
[0135] In some embodiments, both the first cover plate 621 and the second cover plate 622 include a photoelectric sensor mounting portion 623 for mounting the photoelectric sensor G. There are multiple photoelectric sensor mounting portions 623, each located on one side of the receiving channel.
[0136] For example, the first cover plate 621 includes a photoelectric sensor mounting part 623, and the two photoelectric sensor mounting parts 623 are respectively located on both sides of the receiving channel.
[0137] In some implementations, two of a pair of photoelectric sensors G are directed towards each other. Each pair of photoelectric sensors G forms a detection optical path, and the distance between the two detection optical paths is greater than the diameter of the cable L. When the charging gun 20 is in position, the charging gun 20 blocks all detection optical paths, causing at least two pairs of photoelectric sensors G to be triggered.
[0138] In some embodiments, the charging gun receiving portion 62 further includes at least one pair of optical path channels T, each pair of optical path channels T including a first channel and a second channel, and at least one photoelectric sensor G is disposed in both the first channel and the second channel. The detection light emitted by the photoelectric sensor G in the first channel passes through the first channel, passes through the receiving channel, and enters the second channel, where it is received by the photoelectric sensor G in the second channel. "Triggered by a pair of photoelectric sensors G" refers to the activation of one of the photoelectric sensors G used to receive the detection light.
[0139] Optionally, the optical path channel T is a through hole. The through hole can be circular or square, etc.
[0140] like Figure 11 As shown, exemplarily, the first cover plate 621 includes a third optical path channel T3, a fourth optical path channel T4, a seventh optical path channel T7, and an eighth optical path channel T8. A third photoelectric sensor G3 is disposed in the third optical path channel T3, a fourth photoelectric sensor G4 is disposed in the fourth optical path channel T4, a seventh photoelectric sensor G7 is disposed in the seventh optical path channel T7, and an eighth photoelectric sensor G8 is disposed in the eighth optical path channel T8. The third optical path channel T3 and the fourth optical path channel T4 form a pair of optical path channels T, and the seventh optical path channel T7 and the eighth optical path channel T8 form a pair of optical path channels T.
[0141] like Figure 12As shown, exemplarily, the second cover plate 622 includes a first optical path channel T1, a second optical path channel T2, a fifth optical path channel T5, and a sixth optical path channel T6. A first photoelectric sensor G1 is disposed in the first optical path channel T1, a second photoelectric sensor G2 is disposed in the second optical path channel T2, a fifth photoelectric sensor G5 is disposed in the fifth optical path channel T5, and a sixth photoelectric sensor G6 is disposed in the sixth optical path channel T6. The first optical path channel T1 and the second optical path channel T2 form a pair of optical path channels T, and the fifth optical path channel T5 and the sixth optical path channel T6 form a pair of optical path channels T.
[0142] Please see Figure 13 , Figure 13 The cable drive assembly provided in this application embodiment is in Figure 9 The sectional view at section line AA in the diagram. (Example) Figure 13 As shown, in the first pair of photoelectric sensors G, the first photoelectric sensor G1 and the second photoelectric sensor G2 are photoelectricly opposed to each other, forming the first detection optical path J1. In the second pair of photoelectric sensors G, the third photoelectric sensor G3 and the fourth photoelectric sensor G4 are photoelectricly opposed to each other, forming the second detection optical path J2.
[0143] In some implementations, at least two pairs of photoelectric sensors G are located on the same detection plane. Here, "located on the same detection plane" can mean approximately on the same detection plane. For example, Figure 12 The first photoelectric sensor G1 and the second photoelectric sensor G2 in the middle Figure 11 The third photoelectric sensor G3 and the fourth photoelectric sensor G4 are located on the first detection plane P1. Figure 12 The fifth photoelectric sensor G5 and the sixth photoelectric sensor G6 in the middle Figure 11 The seventh photoelectric sensor G7 and the eighth photoelectric sensor G8 are located on the second detection plane P2.
[0144] In some implementations, the number of detection planes is one or more.
[0145] In some implementations, the first distance between the two furthest points of the cross-section of each detection plane when the charging gun 20 is in place is greater than the diameter of the cable L.
[0146] Optionally, the difference between the first distance and the diameter of the cable L is greater than a preset difference.
[0147] Optionally, the number of photoelectric sensors G is four or more pairs, with at least two pairs of photoelectric sensors G located on a detection plane, thereby forming at least two detection planes, each located at a different position.
[0148] In some implementations, the detection plane is a horizontal plane or an inclined plane.
[0149] In some implementations, the detection optical paths formed by at least two pairs of photoelectric sensors G located on the same detection plane are parallel to each other.
[0150] like Figure 13 As shown, for example, the first detection optical path J1 and the second detection optical path J2 are parallel to each other.
[0151] Optionally, the distance between the two detection optical paths is greater than the diameter of the cable L. When the charging gun 20 is in position, it blocks all detection optical paths, causing at least two pairs of photoelectric sensors G to be triggered.
[0152] In some implementations, all optical paths T are located within the same detection plane.
[0153] In some implementations, at least two pairs of optical path channels T are located on a first detection plane P1, and at least two pairs of optical path channels T are located on a second detection plane P2, wherein the first detection plane P1 and the second detection plane P2 are different. For example, Figure 12 The first optical path channel T1 and the second optical path channel T2 in the middle Figure 11 The third optical path channel T3 and the fourth optical path channel T4 are located on the first detection plane P1. Figure 12 The fifth optical path channel T5 and the sixth optical path channel T6 in the middle Figure 11 The seventh optical path channel T7 and the eighth optical path channel T8 are located on the second detection plane P2. In this way, not only can the arrival time of the charging gun 20 be adjusted by using the detection plane at different positions, but the detection plane can also be easily adjusted to make the charging pile 1 suitable for detecting the arrival of different models of charging guns 20.
[0154] In some implementations, the housing K of the optical path channel T employs a light-shielding structure. This prevents ambient light from affecting the detection accuracy of the photoelectric sensor G.
[0155] Among them, a light-blocking structure refers to a structure that is not transparent to light.
[0156] Alternatively, the light-shielding structure can be made of opaque materials or by spraying other media with paint.
[0157] Optionally, the number of optical path channels T is equal to or greater than the number of photoelectric sensors G. When the number of optical path channels T is greater than the number of photoelectric sensors G, it is easier to adjust the position of the photoelectric sensors G according to the diameter of the end of the charging gun 20.
[0158] like Figure 11 and Figure 12As shown, in some embodiments, at least one optical path channel T has a clearance S at its channel outlet, which allows blockages at the channel outlet of the optical path channel T to slide off. In actual use, the charging gun 20 often rubs against the charging gun receiving part 62, potentially generating plastic powder that blocks the channel opening of the optical path channel T, interfering with the photoelectric sensor G. Foreign objects may also enter the charging gun receiving part 62 through the outlet of the charging pile 1, thus blocking the channel opening of the optical path channel T. In this way, when a blockage is about to block the channel opening of the optical path channel T, the blockage can slide off along the clearance S, thereby preventing the blockage from blocking the channel opening of the optical path channel T and improving detection accuracy.
[0159] Alternatively, the material powder can be silica gel powder or rubber powder.
[0160] Optionally, the clearance portion S is a groove and communicates with the optical path channel T. After passing through the optical path channel T and the clearance portion S, the detection optical path enters the receiving channel to be directed towards the charging gun 20.
[0161] like Figure 11 As shown, by way of example, a first clearance section S1 is provided at the channel outlet of the third optical path channel T3 and the seventh optical path channel T7, and a second clearance section S2 is provided at the channel outlet of the fourth optical path channel T4 and the eighth optical path channel T8.
[0162] like Figure 12 As shown, by way of example, a third clearance section S3 is provided at the channel outlet of the first optical path channel T1 and the fifth optical path channel T5, and a fourth clearance section S4 is provided at the channel outlet of the second optical path channel T2 and the sixth optical path channel T6.
[0163] like Figure 5 As shown, in some embodiments, the charging pile 1 further includes a turntable fixing device 80 for fixing the turntable 50. The turntable fixing device 80 includes a turntable fixing back plate 81 and a turntable fixing frame 82.
[0164] In some implementations, the cable drive assembly 60 is located at the outlet H of the charging pile 1.
[0165] In some implementations, the charging pile 1 also includes a fault detection device.
[0166] Optionally, the fault detection device includes a first fault detection device and a second fault detection device. The first fault detection device is installed in a first detection area corresponding to the first motor 30, and the second fault detection device is installed in a second detection area corresponding to the second motor 40.
[0167] In some embodiments, both the first fault detection device and the second fault detection device include Hall sensors. The first fault detection device may be installed at the power line port of the first motor 30, and the second fault detection device may be installed at the power line port of the second motor 40.
[0168] In some embodiments, the charging pile 1 further includes a first motor monitoring device and a second motor monitoring device. The first motor monitoring device is installed in a first monitoring area corresponding to the first motor 30, and the second motor monitoring device is installed in a second monitoring area corresponding to the second motor 40. The first motor monitoring device is used to monitor a first operating parameter of the first motor 30, and the second motor monitoring device is used to monitor a second operating parameter of the second motor 40.
[0169] Optionally, the first operating parameter includes at least the first pulse number of the first motor 30.
[0170] Optionally, the first operating parameters may also include the duty cycle, operating voltage, operating current, and power of the first motor 30.
[0171] Optionally, the second operating parameter includes at least the second pulse number of the second motor 40.
[0172] Optionally, the second operating parameters may also include the duty cycle, operating voltage, operating current, and power of the second motor 40.
[0173] In some embodiments, the charging station 1 also includes a light-emitting device.
[0174] Optionally, the light-emitting device can be used to indicate the usage status of the charging station 1.
[0175] Optionally, the light-emitting device may include an LED light strip.
[0176] like Figure 5 As shown, in some embodiments, the charging pile 1 further includes a power module D, which provides power to the control module 10, the first motor 30, and the second motor 40.
[0177] Optionally, the power module D may be connected to AC power or may include a battery.
[0178] In some embodiments, the charging station 1 also includes a light-emitting device.
[0179] Optionally, the light-emitting device can be used to indicate the usage status of the charging station 1.
[0180] Optionally, the light-emitting device may include an LED light strip.
[0181] In some embodiments, the charging pile 1 also includes a voice broadcasting device Y.
[0182] In some embodiments, the charging pile 1 includes a control module 10, a first motor 30, a second motor 40, a turntable 50, a cable drive unit 61, a cable L, and a charging gun 20. The cable L is wound around the turntable 50 and passes through the cable drive unit 61, and the end of the charging gun 20 is connected to the cable. The first motor 30 drives the turntable 50 to rotate, and the second motor 40 drives the cable drive unit 61 to rotate. The control module 10 controls the first motor 30 and the second motor 40 to gradually retract the cable into or out of the charging pile 1, thereby retracting or extending the charging gun 20.
[0183] In summary, this application provides a charging pile 1, which includes a control module 10, a first motor 30, a second motor 40, a turntable 50, a cable drive unit 61, a cable L, and a charging gun 20. The cable L is wound around the turntable 50 and passes through the cable drive unit 61, and the end of the charging gun 20 is connected to the cable. The first motor 30 drives the turntable 50 to rotate, and the second motor 40 drives the cable drive unit 61 to rotate. The control module 10 controls the first motor 30 and the second motor 40 to extend or retract the charging gun 20. This application uses a first motor 30 to drive the turntable 50 to rotate and a second motor 40 to drive the cable drive unit 61 to rotate. The first motor 30 and the second motor 40 can drive the cable L to move to achieve cable take-up or take-up. During the take-up or take-up process, the tension of the part of the cable L1 that is about to be wrapped on the turntable 50 is adjusted to a suitable tension range, so that the cable L can be tightly wrapped on the turntable 50, preventing the part of the cable L wrapped on the turntable 50 from becoming loose, thereby avoiding the problem of cable L getting stuck or the charging pile 1 not being able to fully accommodate the cable L.
[0184] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
