Description

Technical Field

[0001] This application relates to the technical field of charging pile cable winding devices, and in particular to a charging cable management device and a charging pile. Background Technology

[0002] Charging stations can be fixed to the ground or walls and installed in public parking lots, residential parking lots, or charging stations to charge various models of electric vehicles according to different voltage levels. Generally, charging stations are equipped with charging guns, which are connected to the charging station via charging cables. During or after charging, the charging cable may fall to the ground or even be run over by vehicles, potentially damaging the cable and affecting its lifespan. Especially when the cable diameter exceeds 30mm or the length exceeds 5 meters, the process of removing the charging gun from the charging station and inserting it into the vehicle requires overcoming the weight of the cable itself (typically 5-20kg), the frictional resistance between the cable and the ground, and the force required to rotate the cable, making the operation very strenuous, particularly for women, resulting in a very poor charging experience.

[0003] Therefore, it is desirable to provide a charging gun management device that reduces the resistance that users need to overcome when using the charging gun, simplifies operation, and improves the user experience. Utility Model Content

The main body is provided with a coil and an elastic element connected to the movable part. The movable part fixes the limiting part under the elastic force of the elastic element. The limiting part is fixedly connected to the rotating shaft and moves synchronously with the rotating shaft.

[0012] In some embodiments of this application, the device further includes a controller, which is electrically connected to the coils on the stator and the coils on the braking mechanism, respectively, and the controller is configured to control the coil current on the stator and the coil current on the braking mechanism, respectively.

[0013] In some embodiments of this application, the device further includes an encoder, one end of which is connected to the controller and the other end of which is connected to the rotating shaft, the encoder being used to generate rotational displacement of the rotating shaft.

[0016] In some embodiments of this application, the charging pile further includes a remote control device for sending remote control signals to the controller.

Figure 5 This is a cross-sectional structural schematic diagram of a gun wire management device according to some embodiments of this application.

[0031] refer to Figure 1 As shown in the figure, this application provides a wire management device 100. The wire management device 100 includes: a housing 110; and a detachable wire spool cover 120 located at one end of the housing 110. The housing 110 is cylindrical and is used to house components such as a stator, rotor, and shaft (described below). The wire spool cover 120 is used to protect the winding spool located inside the wire spool cover 120.

[0032] Continue to refer to Figure 1 As shown, the housing 110 is provided with a collar 111 that circumferentially sleeves and fixes the housing 110, and a mounting structure 112 connected to the collar 111 for mounting the housing 110 onto a charging pile. The mounting structure 112 has mounting holes and can be mounted onto the charging pile with screws.

[0033] Continue to refer to Figure 1 As shown, the housing 110 is also provided with a wire interface 113. The wire 114 passes through the wire interface 113 and is electrically connected to the corresponding components (such as controllers and coils) inside the housing 110 to supply power to them.

[0034] refer to Figure 2As shown, after removing the reel cover 120, a winding reel 130 located inside the reel cover 120 is exposed. The winding reel 130 is used to wind the wire. One end of the wire is connected to and wound around the winding reel 130. When the winding reel 130 rotates in a first direction, the wire is unwound; when the winding reel 130 rotates in a second direction, the wire is wound up. The other end of the wire can be connected to the gun wire via a cable clamp. The wire can be PE rope, nylon rope, or steel wire rope, preferably PE rope; however, this application is not limited to this. The wire can also be made of other abrasion-resistant materials, such as Kevlar rope.

[0035] refer to Figure 3 As shown, the winding reel 130 is removed, exposing the rotating shaft 140 connected to the winding reel 130. The winding reel 130 can be rotated by the rotating shaft 140. The rotating shaft 140 extends from inside the housing 110.

[0036] refer to Figure 4 and Figure 5 As shown, the housing 110 contains a stator 150, a rotor 160 rotating around the stator 150, and a rotating shaft 140 fixedly connected to the rotor 160. One end of the rotating shaft 140 is fixedly connected to the center of the rotor 160, and the rotating shaft 140 is configured to be driven to rotate by the rotor 160. The other end of the rotating shaft 140 is embedded in the center of the winding reel 130 and fixedly connected to the center of the winding reel 130, and the winding reel 130 is configured to be driven to rotate by the rotating shaft 140. A coil is wound on the stator 150. The coil is powered by the wire 114. By controlling the current switch in the coil and the current magnitude, the torque generated by the rotor 160 and the rotating shaft 140 can be controlled, and the torque magnitude can be controlled, thereby controlling the winding reel 130 to unwind or rewind the wire. The technical solution of this application utilizes an electrically controlled wire management device 100 to assist the user in using the charging gun, controlling the coil current so that the rotating shaft 140 generates torque to balance the weight of the charging gun, reducing the force required by the user.

[0037] refer to Figure 4 and Figure 5 As shown, the rotor 160 is in the shape of a cover, covering the outer ring of the stator 150, and the rotating shaft 140 passes through the center of the rotor 160 and is fixedly connected to the center of the rotor 160 at the point of penetration.

[0038] Continue to refer to Figure 4 and Figure 5As shown, a first bearing 141 and a second bearing 142 are fitted onto the rotating shaft 140. The first bearing 141 and the second bearing 142 assist the rotating shaft 140 in rotating more smoothly. The lower end 141a of the first bearing 141 is supported by the rotating shaft 140 on its inner side, and the outer side of the lower end 141a of the first bearing 141 is supported by the housing 110. The upper end 141b of the first bearing 141 supports the rotor 160 on its inner side. The lower end 142a of the second bearing 142 is supported by a braking mechanism on its outer side, and the upper end 142b of the second bearing 142 is limited by the housing 110 on its outer side. The upper end 142b of the second bearing 142 supports the rotating shaft 140 on its inner side. Specifically, a support portion 115 with an approximately L-shaped cross-section extends from the inner side of the housing 110. The two ends of the support portion 115 respectively form limiting portions that limit the outer rings of the first bearing 141 and the second bearing 142, partially fixing and supporting the outer rings of the first bearing 141 and the second bearing 142. A stator receiving cavity is formed between the support portion 115 and the outer shell 110 to accommodate the stator 150.

[0039] Continue to refer to Figure 4 and Figure 5 As shown, the top surface of the support 115 is also provided with a limiting structure 116 by screws, which is used to axially limit the first bearing 141 and the rotor 150.

[0040] Continue to refer to Figure 4 and Figure 5 As shown, the gun wire management device 100 further includes a braking mechanism 143, which is connected to the rotating shaft 140 and is used to prevent the rotating shaft 140 from rotating. Specifically, the braking mechanism 143 includes a main body 143a, a movable part 143b, and a limiting part 143c. The main body 143b is provided with a coil and an elastic element connected to the movable part. The movable part fixes the limiting part under the elastic force of the elastic element. The limiting part is fixedly connected to the rotating shaft and moves synchronously with the rotating shaft. The movable part is, for example, a flat plate structure and is magnetic. The limiting part has an L-shaped cross-section, and the movable part abuts against the bottom edge of the L. The side edge of the L engages with the second threaded structure of the side wall of the rotating shaft through a first threaded structure. When the coil on the main body is not energized, the movable part abuts against and fixes the limiting part under the elastic force of the elastic element, thereby fixing the rotating shaft and preventing it from rotating. When the coil on the main body is energized, the magnetic field generated by the coil attracts the movable part, thereby releasing the limiting part and then releasing the rotating shaft so that the rotating shaft can rotate.

[0041] Continue to refer to Figure 4 and Figure 5As shown, the gun wire management device 100 further includes a controller 170, which is electrically connected to the coils on the stator 150 and the coils on the brake mechanism 143, respectively. The controller is configured to control the coil current on the stator and the coil current on the brake mechanism, respectively. The controller 170 is, for example, a circuit board. The controller 170 is powered by a wire 114. The controller is pre-set with at least one output torque-displacement correspondence curve formed by a plurality of preset shaft output torques that correspond one-to-one with a plurality of preset displacements (e.g., ...). Figure 6 The shaft torque control curve shown is as follows. Figure 8 The take-up and let-out curves shown are designed to match the pulling force on the gun line generated by the output torque of the shaft through the line with the nominal weight of the gun line.

[0042] Continue to refer to Figure 4 and Figure 5 As shown, in some embodiments of this application, the gun wire management device 100 further includes an encoder 180, one end of which is connected to the controller 170, and the other end of which is connected to the rotating shaft 140. The encoder 180 is used to generate the rotational displacement of the rotating shaft 140.

[0043] Continue to refer to Figure 4 and Figure 5 As shown, in some embodiments of this application, the gun wire management device 100 further includes: a housing accommodating the stator, rotor, and shaft; the top of the housing 110 has a top cover 121 and a first sealing ring 122 located between the housing and the top cover; the bottom of the housing 110 has a bottom cover 123 and a second sealing ring 124 located between the housing and the bottom cover; the bottom of the housing has a recess and a cover 125 that closes the recess and a third sealing ring 126 located between the housing and the cover.

[0044] In some embodiments of this application, the nominal weight of the charging cable refers to the tension exerted on the charging cable's connection end relative to the initial position when the operator holds the charging gun almost still. Without external force, the output torque of the rotor shaft generated by the coil current on the stator always drives the winding reel to wind the cable, that is, drives the winding reel to rotate in the winding direction, causing the cable's connection end to move back to the initial position, thus generating a lifting force on the cable. In other words, without external force, the coil current on the stator always causes the rotor to tend to rotate in the winding direction to generate the shaft output torque. "Matching" means that the lifting force exerted on the cable through the cable by the shaft output torque is very close to the nominal weight of the cable, and is comparable to the total static friction generated by the various components. For example, the difference between the lifting force exerted on the cable through the cable by the shaft output torque and the nominal weight of the cable is less than or equal to 20N. Preferably, the pulling force exerted on the charging cable by the output torque of the swivel through the cable differs from the nominal weight of the charging cable by less than or equal to 15N. More preferably, the pulling force exerted on the charging cable by the output torque of the swivel through the cable differs from the nominal weight of the charging cable by less than or equal to 10N. Even more preferably, the pulling force exerted on the charging cable by the output torque of the swivel through the cable differs from the nominal weight of the charging cable by less than or equal to 10N. Ideally, the pulling force exerted on the charging cable by the output torque of the swivel through the cable differs from the nominal weight of the charging cable by less than or equal to 5N, and particularly ideally, less than or equal to 3N. The smaller the difference, the less force the operator needs to pull the charging gun away from the charging station, resulting in a better feel when pulling out the cable.

[0045] In some embodiments of this application, the number of the plurality of displacement quantities is preset in the controller. To achieve a better feel, the more the plurality of displacement quantities, the better, for example, more than 5. However, too many displacement quantities increase the workload during factory setup, and the resulting improvement in feel is not necessarily significant. Therefore, for typical charging piles, the number of the plurality of displacement quantities does not exceed 30. Preferably, the number of the plurality of displacement quantities is greater than or equal to 10 and less than or equal to 20. Ideally, the number of the plurality of displacement quantities is greater than or equal to 12 and less than or equal to 18, for example, 16.

[0046] In some embodiments of this application, the at least one segment of the output torque displacement corresponding curve includes a converging curve ( Figure 8The take-up curve shown is such that the pulling force exerted on the charging cable by the cable through the cable, generated by the output torque of the shaft at any preset displacement, is greater than the nominal weight of the charging cable corresponding to that preset displacement (charging cable gravity curve). The take-up curve does not specifically refer to the curve in the take-up state, but rather to the curve where the pulling force exerted on the charging cable through the cable by the output torque of the shaft at any preset displacement is greater than the nominal weight of the charging cable corresponding to that preset displacement. Thus, the pulling force exerted on the charging cable by the charging pile charging cable management device at any point where the cable-charging cable connection end is displaced relative to the initial position is greater than the nominal weight of the charging cable at that point. This causes the cable-charging cable connection end to tend to move towards the initial position until, considering friction, the resultant force of the operator's pulling force and the nominal weight of the charging cable balances the pulling force exerted on the charging cable through the cable by the cable generated by the take-up curve, and the charging cable suspends at the position corresponding to that displacement.

[0047] When the cable is suspended, if the operator increases the pulling force of the cable, the resultant force of the pulling force and the nominal weight of the cable will be greater than the lifting force exerted on the cable by the cable through the cable at that position, meaning that the motor rotor cannot be held in place by the output torque generated by the preset stator current corresponding to the displacement of the cable connection end, which would cause the rotor to rotate in the winding direction. Under the combined force of the operator's pulling force and the nominal weight of the cable, the winding reel rotates in the unwinding direction, releasing the cable. Generally, the resultant force of the operator's pulling force and the nominal weight of the cable will decrease as the displacement of the cable connection end increases. At the same time, the lifting force exerted on the cable by the cable decreases according to the winding curve until a certain displacement position is reached, where the resultant force of the operator's pulling force and the nominal weight of the cable balances the lifting force exerted on the cable by the cable through the cable at that position, and the cable is suspended at that position. If the operator reduces the pulling force of the gun line, the resultant force of the operator's pulling force and the nominal weight of the gun line decreases. At the same time, the lifting force of the line acting on the gun line decreases according to the take-up curve. The resultant force of the operator's pulling force and the nominal weight of the gun line balances the lifting force of the line acting on the gun line through the line generated by the take-up curve at that position, and the gun line hangs at that position.

[0048] In some embodiments of this application, reference is made to Figure 8 As shown, the device further includes: the at least one output torque displacement corresponding curve also includes a line-laying curve, wherein the pulling force generated by the output torque of the shaft at any preset displacement in the line-laying curve and acting on the gun line through the line is less than the nominal weight of the gun line corresponding to the preset displacement.

[0049] In some embodiments of this application, the actual starting point for reeling in and releasing the cord is slightly longer than the theoretical origin, leaving a safety distance to prevent the cord from impacting the outlet. The origin is recalibrated after each reeling in and release. A safety distance is also left at the end of the cord, so that in case of an accident, such as a user tripping, a certain length can still be released.

[0050] The charging gun management device provided in this application uses a rope to connect the winding reel and the charging gun. The torque of the rotor inside the charging gun management device is almost balanced with the weight of the charging gun. In this way, when the user operates the charging, he only needs to lift the weight of the charging gun by hand to move the charging gun to the vehicle position for charging, which greatly reduces the operation intensity and improves the charging experience.

[0051] Embodiments of this application also provide a charging pile, see reference. Figure 7 As shown, it includes: a charging cable management device 100 as described above; a charging pile body 52, which is electrically connected to the charging cable management device 100 via a wire 114; a charging cable 51, one end of which is electrically connected to the charging pile body 52, one end of the cable of the charging cable management device is fixed to the middle of the charging cable, and the other end of the cable of the charging cable management device is fixed to the winding reel; a charging gun 53, one end of which is electrically connected to the other end of the charging cable 51, and the other end of which is used to connect to the charging interface of an electric vehicle; and a charging gun holder 54, which is detachably connected to the charging gun 53.

[0052] In some embodiments of this application, the charging gun holder 54 may be disposed on the charging pile body 52.

[0053] In some embodiments of this application, the charging pile body 52 can output voltage to power the charging gun management device 100, and at the same time, when connected to the electric vehicle through the charging gun 51 and the charging gun 53, it can charge the electric vehicle.

[0054] In some embodiments of this application, the charging cable management device 100 is fixedly disposed on the top of the charging pile body 52. ​​This increases the length of the charging cable 51, thereby increasing the probability that the charging pile can be connected to the electric vehicle via the charging cable 51 and the charging gun 53, and thus increasing the usage frequency of the charging pile.

[0055] In some embodiments of this application, the charging gun 53 or the charging gun socket is provided with a sensing device that is communicatively connected to the controller. When the charging gun 53 is removed from the charging gun socket 54, the sensing device sends a wire release signal to the controller; when the charging gun 53 is removed from the charging interface of the electric vehicle, the sensing device sends a wire retraction signal to the controller; when the charging gun 53 is inserted into the charging gun socket 54, the sensing device sends a standby signal to the controller; when the charging gun 53 is inserted into the charging interface of the electric vehicle, the sensing device sends a charging signal to the controller.

[0056] In some embodiments of this application, the charging pile further includes a remote control device for sending remote control signals to the controller. The remote control device can be a physical device mounted on the charging pile body 52. ​​Alternatively, the remote control device can be a virtual program mounted on a user's mobile phone or the display software on the charging pile body 52.

[0057] The beneficial effects that the embodiments of this application may bring include, but are not limited to: under the control of the charging gun management device 100 and / or the charging pile, after the charging gun 53 is used up and during the charging process, the charging gun 51 can be kept from falling to the ground, thereby improving the service life of the charging gun 51; and during user use, it can assist the user in reeling in or releasing the charging gun 51, balance the weight of the charging gun 51, and improve the user experience.

[0058] The charging gun management device and charging pile provided in this application embodiment connect the winding reel and the charging gun with a rope. The torque of the rotor inside the charging gun management device is almost balanced with the weight of the charging gun. In this way, when the user operates the charging, he only needs to lift the weight of the charging gun by hand to move the charging gun to the vehicle position for charging, which greatly reduces the operation intensity and improves the charging experience.
