The cable outlet position on the existing cable reel is fixed. After the cable is recovered, the cable is easily unevenly arranged and the cable is entangled and knotted, which affects the convenience of the user's subsequent use of the charging pile. There is room for improvement. Utility Model Content
[0005] In order to reduce the occurrence of entanglement, knotting, and uneven arrangement of cables during the process of reeling and releasing the cables, and to ensure the convenience of users in using the cable reel, the present application provides an automatic cable arrangement mechanism for reeling and releasing the cables.
[0006] The present application provides an automatic cable arrangement mechanism for a cable reel for reeling and unreeling a cable, which adopts the following technical solution:
[0007] An automatic cable arrangement mechanism for a cable reel for reeling in and out a cable, comprising a reel hub rotatably mounted in a charging pile housing, the reel hub comprising a first side plate and a second side plate;
[0008] A reciprocating screw rod is rotatably connected to the charging pile housing, a wire rack is slidably connected to the reciprocating screw rod, and a wire hole is provided on the wire rack for extending or retracting the cable;
[0009] A servo motor is fixedly connected in the housing of the charging pile, and a first transmission assembly is arranged on the first side plate, one end of the first transmission assembly is in transmission cooperation with the servo motor, and one end of the first transmission assembly away from the servo motor is in transmission cooperation with the first side plate;
[0010] A second transmission assembly is disposed on the second side plate, one end of the second transmission assembly is in transmission cooperation with the second side plate, and one end of the second transmission assembly away from the second side plate is in transmission cooperation with the reciprocating screw rod;
[0011] The servo motor drives the reel hub to rotate in the unwinding direction or the rewinding direction, and at the same time drives the wire rack to slide back and forth along the axial direction of the reciprocating screw rod.
[0012] By adopting the above technical solution, when the user uses the charging pile, the control command of the wire release can be input through the control panel on the charging pile. After receiving the control command of the wire release, the servo motor drives the first side plate to rotate through the first transmission component to drive the reel hub to rotate, thereby achieving the technical effect of releasing the cable. Due to the transmission cooperation between the first transmission component and the second transmission component, while the servo motor drives the first transmission component to operate, the second transmission component drives the wire rack to slide back and forth along the axial direction of the screw rod, so that the wire hole on the wire rack moves back and forth, so that the center of the wire hole is aligned with the axis of the cable. During the wire winding process, the second transmission component drives the wire rack to slide back and forth on the reciprocating screw rod, which can drive the cables to be arranged and wound on the winding column in sequence, thereby achieving the technical effect of automatic wire arrangement, which can reduce the occurrence of chaotic cable arrangement, entanglement, and knotting during the wire winding process of the reel, and can reduce the occurrence of subsequent wire jamming caused by cable entanglement and knotting of the reel, thereby improving the stability of the reel.
[0013] Preferably, the first transmission assembly includes a first synchronous wheel, a first driven gear ring and a first synchronous belt, the first driven gear ring is sleeved and fixed on the bearing of the first synchronous wheel, a transmission inner gear ring is fixedly connected to the outer wall of the first side plate, the first driven gear ring is meshed with the transmission inner gear ring, and the first synchronous belt is sleeved on the driving shaft of the servo motor and the outer side of the first synchronous wheel.
[0014] By adopting the above technical solution, the first synchronous belt transmits the driving action of the driving motor to the first synchronous wheel and the first driven gear ring, and then transmits it to the first driven gear ring. The rotation of the first driven gear ring can drive the transmission inner gear ring to rotate, so as to drive the first side plate and the reel hub to rotate in the winding direction or the unwinding direction at the same time, thereby realizing the technical effect of automatic winding and unwinding.
[0015] Preferably, the second transmission assembly includes a second synchronous wheel, a second driven gear ring and a second synchronous belt, the second synchronous wheel is fixedly connected to the outer wall of the second side plate, the second driven gear ring is coaxially sleeved and fixed on the end of the reciprocating screw, and the second synchronous belt is sleeved on the outer side of the second synchronous wheel and the second driven gear ring.
[0016] By adopting the above technical solution, when the servo motor drives the reel hub to rotate, the second synchronous wheel on the second side plate rotates, and the second transmission belt can drive the second driven gear ring to rotate, and then drive the reciprocating screw to rotate synchronously. The rotation of the reciprocating screw can drive the wire rack to reciprocate along the axial direction of the reciprocating screw, which can ensure that the wire rack is facing the cable retraction and release position during the wire reeling and releasing process.
[0017] Preferably, it further comprises a third synchronous wheel, and a driven shaft is sleeved and fixed on the bearing of the second synchronous wheel;

[0020] The wire rack is provided with an axial hole for the driven shaft to pass through, and the driven shaft is meshed with the two third driven gear rings.
[0021] By adopting the above technical solution, when the servo motor drives the reel hub to rotate, the servo motor driving action is transmitted to the driven shaft through the third synchronous wheel and the third synchronous belt. The driven shaft can drive the first roller and the second roller to rotate through the third driven gear ring and the fourth driven gear ring. The wheel surfaces of the first roller and the second roller contact with the cable and generate friction, which can drive the cable to be released or retracted, thereby reducing the occurrence of partial accumulation of the cable in the reel, and further improving the smoothness of the reel to reel in and out.
[0022] Preferably, the first roller and the second roller are arranged in a funnel shape.
[0023] By adopting the above technical solution, the first roller and the second roller are arranged in a funnel shape so that the wire hole formed between the wheel surfaces of the first roller and the second roller can be approximately elliptical, which can reduce the possibility of cable damage during the retraction and release process.
[0024] Preferably, friction textures are arranged on the wheel surfaces of the first roller and the second roller.
[0025] By adopting the above technical solution, the friction texture can increase the friction between the wheel surface of the first roller and the second roller and the cable, thereby improving the stability of the first roller and the second roller when reeling in and releasing the cable.
[0026] In summary, the present invention provides an automatic cable arrangement mechanism for a cable reel for reeling and unreeling a cable, which includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-3 This application is described in further detail.
[0034] Example
[0035] The present application embodiment discloses an automatic cable arrangement mechanism for a cable reel for reeling in and out cables. Figure 1 and Figure 2 , which mainly includes a reel hub 1. The reel hub 1 is rotatably installed in the housing of the charging pile through an installation shaft, and the reel hub 1 includes a first side plate 11 and a second side plate 12; a reciprocating screw rod 2 is rotatably connected in the housing of the charging pile, and a wire rack 3 is slidably connected to the reciprocating screw rod 2, and a wire rack 3 is provided on the wire rack 3. A wire hole 31 for extending or retracting the cable is provided.
[0036] A servo motor 6 is fixedly connected inside the casing of the charging pile, and a first transmission assembly 4 is provided on the first side plate 11 . One end of the first transmission assembly 4 is in transmission cooperation with the servo motor 6 , and the end of the first transmission assembly 4 away from the servo motor 6 is in transmission cooperation with the first side plate 11 .
[0037] A second transmission assembly 5 is provided on the second side plate 12, one end of the second transmission assembly 5 is in transmission cooperation with the second side plate 12, and one end of the second transmission assembly 5 away from the second side plate 12 is in transmission cooperation with the reciprocating screw rod 2; the servo motor 6 drives the reel hub to rotate in the pay-off direction or the take-up direction, and at the same time drives the wire rack 3 to slide back and forth along the axial direction of the reciprocating screw rod 2.
[0038] When the user uses the charging pile, the user can input the line-releasing control instruction through the control panel on the charging pile. After receiving the line-releasing control instruction, the servo motor 6 drives the first side plate 11 to rotate through the first transmission assembly 4 to drive the reel hub 1 to rotate, thereby achieving the technical effect of releasing the cable.
[0039] Due to the transmission cooperation between the first transmission assembly 4 and the second transmission assembly 5, while the servo motor 6 drives the first transmission assembly 4 to operate, the second transmission assembly 5 drives the wire rack 3 to slide back and forth along the axial direction of the screw rod, so that the wire hole 31 on the wire rack 3 moves back and forth, so that the center of the wire hole 31 is aligned with the axis of the cable.
[0040] During the wire winding process, the second transmission assembly 5 drives the wire rack 3 to slide back and forth on the reciprocating screw rod 2, which can drive the cables to be arranged in sequence and wound on the winding column, thereby achieving the technical effect of automatic wire arrangement, reducing the occurrence of chaotic cable arrangement, entanglement, and knotting during the wire winding process of the cable reel, reducing the occurrence of subsequent wire jamming caused by cable entanglement and knotting on the cable reel, and improving the stability of the cable reel.
[0041] Reference Figure 1 and Figure 2The first transmission assembly 4 includes a first synchronous wheel 41, a first driven gear ring 42 and a first synchronous belt 43. The first driven gear ring 42 is sleeved and fixed on the bearing of the first synchronous wheel 41.

The first synchronous belt 43 is sleeved on the driving shaft of the servo motor 6 and the outer side of the first synchronous wheel 41.
[0042] The first synchronous belt 43 transmits the driving action of the driving motor to the first synchronous wheel 41 and the first driven gear ring 42, and then transmits it to the first driven gear ring 42. The rotation of the first driven gear ring 42 can drive the transmission inner gear ring 111 to rotate, so as to drive the first side plate 11 and the reel hub 1 to rotate in the winding direction or the unwinding direction at the same time, thereby achieving the technical effect of automatic winding and unwinding.
[0043] Reference Figure 1 and Figure 2 The second transmission assembly 5 includes a second synchronous wheel 51, a second driven gear ring 52 and a second synchronous belt 53. The second synchronous wheel 51 is fixedly connected to the outer wall of the second side plate 12. The second driven gear ring 52 is coaxially sleeved and fixed on the end of the reciprocating screw 2. The second synchronous belt 53 is sleeved on the outer sides of the second synchronous wheel 51 and the second driven gear ring 52.
[0044] When the servo motor 6 drives the reel hub 1 to rotate, the second synchronous wheel 51 on the second side plate 12 rotates, and through the second transmission belt transmission, it can drive the second driven gear ring 52 to rotate, and then drive the reciprocating screw rod 2 to rotate synchronously. The rotation of the reciprocating screw rod 2 can drive the wire rack 3 to reciprocate along the axial direction of the reciprocating screw rod 2, which can ensure that the wire rack 3 is facing the cable retracting and releasing position during the wire reeling and releasing process.
[0045] Reference Figure 1 and Figure 3 , and also includes a third synchronous wheel 32, and the third synchronous wheel 32 is installed in the housing of the charging pile, and a driven shaft 33 is sleeved and fixed on the bearing of the second synchronous wheel 51.
[0046] The wire rack 3 includes a mounting cavity 34 , in which a first roller 35 and a second roller 36 are rotatably connected, and a wire passing hole 31 is formed between the first roller 35 and the second roller 36 .
[0047] Two third driven gear rings 351 are fixedly connected to both ends of the first roller 35 , and two fourth driven gear rings 361 are fixedly connected to both ends of the second roller 36 . Adjacent third driven gear rings 351 are meshed with the fourth driven gear rings 361 .
[0048] The wire rack 3 is provided with a shaft hole 37 for the driven shaft 33 to pass through, and the driven shaft 33 is meshed with two third driven gear rings 351 .
[0049] When the servo motor 6 drives the reel hub 1 to rotate, the driving action of the servo motor 6 is transmitted to the driven shaft 33 through the third synchronous wheel 32 and the third synchronous belt 38. The driven shaft 33 can drive the first roller 35 and the second roller 36 to rotate through the third driven gear ring 351 and the fourth driven gear ring 361. The wheel surfaces of the first roller 35 and the second roller 36 contact the cable and generate friction, which can drive the cable to be released or retracted, thereby reducing the occurrence of partial accumulation of the cable in the reel, and further improving the smoothness of the reel to reel in and out.
[0050] Reference Figure 3 The first roller 35 and the second roller 36 are arranged in a funnel shape. The first roller 35 and the second roller 36 are arranged in a funnel shape so that the wire hole 31 formed between the wheel surfaces of the first roller 35 and the second roller 36 is approximately elliptical, which can reduce the damage of the cable during the retracting and releasing process.
[0051] Reference Figure 3 The first roller 35 and the second roller 36 are both provided with friction textures on their surfaces. The friction textures can increase the friction between the surfaces of the first roller 35 and the second roller 36 and the cable, and improve the stability of the first roller 35 and the second roller 36 when retracting and releasing the cable.
