Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Combine fig. 1 and fig. 2 to show, a can fill electric pile of rolling charging wire, including the casing 1 that is used for holding charging wire 9, install in the inside coiling mechanism 3 of below of casing 1. The winding device 3 comprises a winding frame 35 fixed on the shell 1, a winding roller 31 installed on the winding frame 35 and used for winding the charging wire 9, a driving piece 32 used for driving the winding roller 31 to rotate, a guiding mechanism 33 used for guiding the charging wire 9, and a locking mechanism 34 used for blocking the winding roller 31 to wind the charging wire 9, wherein the winding roller 31 is axially fixed and is connected to the winding frame 35 in a circumferential rotating manner. The drive member 32 is a hand wheel.

Take-up roller 31 clockwise rotation rolling charging wire 9 as an example. When winding the charging wire 9, the locking mechanism 34 is unlocked, the driving member 32 drives the winding roller 31 to rotate clockwise, and the charging wire 9 is uniformly wound on the winding roller 31 under the guidance of the guiding mechanism 33.

Referring to fig. 3 and 4, the locking mechanism 34 includes a ratchet 341 fixed at one end of the wind-up roll 31, a pawl 342 engaged with the ratchet 341, a reset member 343 mounted on the wind-up frame 35 and used for abutting the pawl 342 against the ratchet 341, and an unlocking assembly 344 used for driving the pawl 342 away from the ratchet 341, wherein the ratchet 341 and the pawl 342 are axially fixed and circumferentially rotatably connected to the wind-up frame 35. The reset member 343 is a spring fixed in a compressed state between the inner wall of the housing 1 and the pawl 342. The unlocking assembly 344 includes a rotating shaft 4 penetrating through and fixed to the pawl 342, a rotating block 5 fixed to one end of the rotating shaft 4 penetrating through the housing 1, and a locking member 6 for locking the relative position of the rotating block 5 and the housing 1, wherein the rotating block 5 is axially fixed and is connected to the outer wall of the housing 1 in a circumferential rotation manner. The shell 1 is provided with a locking hole 11, the outer wall of the shell 1 is fixed with a limiting block 2, and the rotating block 5 is provided with a through hole 51. The locking member 6 is a locking pin which is horizontally inserted through the through hole 51 and the locking hole 11.

For example, when the pawl 342 abuts against the ratchet 341, the ratchet 341 can rotate counterclockwise only. The spring in the compressed state gives the pawl 342 a force toward the ratchet 341, so that the pawl 342 and the ratchet 341 are always pressed against each other without any other external force. When an operator pulls the charging wire 9 to pull the charging wire 9 out of the shell 1, the winding roller 31 rotates anticlockwise. After the charging wire 9 is successfully connected with the electric vehicle, the operator does not pull the charging wire 9 any more, and the wind-up roll 31 stops rotating. At this time, the pawl 342 blocks the ratchet of the ratchet 341, so that the wind-up roll 31 cannot rotate clockwise, thereby maintaining the stability of the connection between the charging wire 9 and the electric vehicle; when charging is completed and the charging wire 9 needs to be wound, the operator rotates the rotating block 5, and the pawl 342 rotates along with the rotating block 5 to resist the force of the reset piece 343 to the pawl 342. When the rotating member is rotated to a proper position, the pawl 342 is disengaged from the ratchet 341. When the rotating block 5 rotates to abut against the limiting block 2, the rotating block 5 does not rotate continuously, at the moment, the locking hole 11 is coaxial with the through hole 51, and the locking piece 6 penetrates through the through hole 51 and the locking hole 11 so as to lock the rotating block 5 and the outer wall of the shell 1 together. Thus, the ratchet wheel 341 is not blocked by the pawl 342, and the driving member 32 can drive the wind-up roll 31 to rotate clockwise.

As shown in fig. 2 and 5, a driving gear 7 is fixed to an end of the wind-up roll 31 away from the ratchet 341. The guide mechanism 33 includes a sliding block 331 slidably attached to the housing 1 in an axial direction parallel to the take-up roller 31, a moving member 332 for sliding the sliding block 331, and a gripping member 333 attached to the sliding block 331 and for gripping the cable. The sliding block 331 is provided with a guide rod 334 extending in parallel to the axial direction of the wind-up roller 31, and both ends of the guide rod 334 are fixed to two opposite side walls of the housing 1. The moving assembly 332 comprises a screw 3321 axially penetrating and threaded to the sliding block 331 along a direction parallel to the winding roller 31, and a moving member 3322 fixed at one end of the screw 3321 and used for driving the screw 3321 to rotate, wherein the screw 3321 is axially fixed and circumferentially rotatably connected to the winding frame 35. The moving member 3322 is a driven gear, and the moving member 3322 and the driving gear 7 are engaged with an annular toothed belt 8. The clamping unit 333 includes two clamping rollers 3331 for abutting against both ends of the charging wire 9 in the diameter direction thereof, and the clamping rollers 3331 are axially fixed and circumferentially rotatably connected to the sliding block 331.

When the driving piece 32 drives the winding roller 31 to rotate clockwise, the driving gear 7 fixed on the winding roller 31 rotates clockwise, the annular toothed belt 8 meshed with the driving gear 7 rotates, the annular toothed belt 8 drives the moving piece 3322 to rotate, and therefore the driving gear 7 and the moving piece 3322 rotate synchronously. At this time, the screw 3321 fixed to the mover 3322 is rotated. Since the guide rod 334 causes the sliding block 331 to slide only in the axial direction parallel to the take-up roller 31 and the screw 3321 is screwed to the sliding block 331, the sliding block 331 slides in the axial direction parallel to the take-up roller 31 after the screw 3321 rotates. In this way, the charging wire 9 held between the two holding rollers 3331 on the slide block 331 moves along with the slide block 331. Thereby changing the position of the charging wire 9 wound on the winding drum. Since the sliding block 331 moves as the winding drum rotates, the distance between the sliding block 331 and the winding drum remains constant. In this way, the charging cord 9 is wound evenly around the take-up reel. When the operator pulls the charging wire 9, the wind-up roller 31 rotates counterclockwise, and the mover 3322 also rotates counterclockwise. In this way, the distance between the sliding block 331 and the wind-up roller 31 remains constant regardless of how the wind-up roller 31 rotates.

The working principle is as follows: when using the charging wire 9 to charge, the operating personnel holds one end of the charging wire 9 and pulls out the charging wire 9 from the shell body 1. The wind-up roll 31 automatically rotates counterclockwise and drives the moving member 3322 to rotate through the annular toothed belt 8. After the mover 3322 rotates, the sliding block 331 slides in a direction parallel to the axial direction of the take-up roller 31. After the plug of the charging wire 9 is successfully connected with the electric vehicle, the pawl 342 abuts against the ratchet wheel 341 under the action of the reset piece 343 to limit the counterclockwise rotation of the ratchet wheel 341 and further limit the counterclockwise rotation of the winding drum fixed with the ratchet wheel 341. The charging wire 9 does not come off the electric vehicle. Thereby, the stability of the connection of the charging wire 9 and the electric vehicle is maintained.

When the charging is completed, the charging wire 9 is disconnected from the electric vehicle. The charging head is placed on the housing 1. The rotating block 5 is rotated to be abutted against the limiting block 2, and the locking piece 6 sequentially penetrates through the through hole 51 and the locking hole 11 to lock the rotating block 5 and the shell 1 together. At this time, the pawl 342 disengages the ratchet 341, and the ratchet 341 can rotate counterclockwise. So, the winding cylinder can rotate anticlockwise. The operator rotates the driving member 32, and the driving member 32 drives the wind-up roll 31 to rotate clockwise and drives the moving member 3322 to rotate clockwise. Thus, the sliding block 331 slides in a direction parallel to the axial direction of the wind-up roller 31. At this time, the sliding direction of the slider 331 is opposite to the direction when the charging wire 9 is pulled. When the sliding block 331 moves to abut against the inner wall of the housing 1, the charging wire 9 is laid flat and wound on the winding roller 31 uniformly. Thus, winding of the charging wire 9 is completed.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
