[0002] At present, the construction of large-scale charging stations requires high investment and the number is limited. In comparison, electric vehicle charging piles that occupy less space and are convenient and fast have more obvious advantages. Charging piles are small power stations for electric vehicles. Their functions are similar to those of gas pumps used in gas stations. They can be widely used in parking lots, residential communities, office buildings and other areas. By using the charging gun on the charging pile, users can easily connect electric vehicles and charge them.

[0003] The length of the cable connecting the charging gun of the existing charging pile is usually several times the height of the charging pile. In the absence of effective storage measures, the cables will be randomly piled on the ground after use and frequently rub against the ground, causing cable wear and leakage, and affecting road traffic around the charging pile.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, reference Figures 1 to 8 , which is the first embodiment of the present invention, and provides a wire collection device for a charging pile, which can achieve the effect of safely and effectively storing the cables of the charging pile, and includes a main body component 100, which includes an electric pile component 101, and an expansion component 102 that slides inside the electric pile component 101, and also includes a deceleration component 103 and a winding component 104 that rotate on the expansion component 102. The expansion component 102 can drive the winding component 104 to expand, and the deceleration component 103 can slow down the driving speed of the expansion component 102; The limiting component 200 includes a ratchet assembly 201 disposed in the electric pile assembly 101, and a driving assembly 202 fixed to the bottom of the ratchet assembly 201. The ratchet assembly 201 is connected to the speed reduction assembly 103, and the driving assembly 202 can drive the ratchet assembly 201 to switch; The limiting component 300 includes an elastic component 301 fixed on the expansion component 102, and a track component 302 adapted for the elastic component 301, and also includes a transmission component 303 fixed at the bottom of the track component 302. The transmission component 303 is connected to the ratchet component 201, and the elastic component 301 can be driven to switch tracks in the track component 302 through the transmission component 303.

[0036] Specifically, the charging pile assembly 101 includes a charging pile 101a, which is provided with a wire combing groove 101b and a convex groove 101c. The wire combing groove 101b and the convex groove 101c are located on the left and right sides of the charging pile. Two reserved grooves 101d are provided between the wire combing groove 101b and the convex groove 101c in the charging pile 101a, and the two reserved grooves 101d are distributed up and down. A sliding groove 101e is provided at the protruding part of the convex groove 101c in the charging pile 101a, a placement groove 101f is provided at the protruding part of the convex groove 101c at the front end of the charging pile 101a, and an electric box 101g is fixed to the top of the charging pile 101a.

[0037] Furthermore, the expansion component 102 includes an outer tube 102a that slides at the bottom of the convex groove 101c, the outer wall of the outer tube 102a is provided with a No. 1 spiral groove 102b, and an inner tube 102c that slides at the top of the outer tube 102a, the outer wall of the inner tube 102c is provided with a No. 2 spiral groove 102d, and also includes a No. 1 spring 102e fixed to the inner wall of the outer tube 102a, and the No. 1 spring 102e is connected to the inner tube 102c.

[0038] Furthermore, the deceleration assembly 103 includes a fixed ring 103a fixed to the middle of the convex groove 101c, and a rotating ring 103b rotating on the inner wall of the fixed ring 103a, a damping fluid is provided between the fixed ring 103a and the rotating ring 103b, and a slider 103c fixed to the inner wall of the rotating ring 103b, the slider 103c is adapted to the No. 1 spiral groove 102b and the No. 2 spiral groove 102d. When in use, the rotating ring 103b slides on the outer wall of the outer tube 102a, and the slider 103c slides inside the No. 1 spiral groove 102b and the No. 2 spiral groove 102d, so that the outer tube 102a and the inner tube 102c can shrink or expand synchronously when moving.

[0039] Furthermore, the winding assembly 104 includes a large roller 104a rotating at the top of the outer tube 102a and the bottom of the inner tube 102c corresponding to the combing groove 101b, the two large rollers 104a are adapted to the two reserved grooves 101d, the two large rollers 104a are initially located at one end of the outer side of the two reserved grooves 101d, and a rubber wheel 104b and a combing wheel 104c rotating between the two large rollers 104a corresponding to the front end of the inner side of the combing groove 101b, the rubber wheel 104b is arranged at the top of the combing wheel 104c, and the combing wheel 104c is at the bottom of the rubber wheel 104b and tilted backwards, so that the wires discharged from the rubber wheel 104b and the combing wheel 104c will tilt downward, so that when the wires are charged, the cables hang on the ground, thereby preventing the cables from being suspended in the air and affecting ground traffic. The wire 104d is wrapped around the large roller 104a and the rubber wheel 104b, and the wire 104d extends from the bottom of the power box 101g to the bottom large roller 104a, and extends to the top large roller 104a after wrapping around the bottom large roller 104a, and extends to the rubber wheel 104b after wrapping around the top large roller 104a, and is led out of the charging pile 101a from the rubber wheel 104b and the combing wheel 104c, and the large roller 104a is used as a support for retracting the wire 104d, and also includes a charging head 104e fixed to one end of the outer side of the wire 104d, the charging head 104e is a buckle in the prior art, and the charging head 104e can be inserted into the placement slot 101f, and is limited in the placement slot 101f by the buckle function of the charging head 104e, and the wire 104d is connected to the power box 101g.

[0040] When in use, the charging head 104e is taken out from the placement groove 101f, and the wire 104d is pulled outward so that the wire 104d squeezes the two large rollers 104a. The two large rollers 104a drive the outer tube 102a and the inner tube 102c to move closer to each other and compress the No. 1 spring 102e. At this time, the No. 1 spiral groove 102b and the No. 2 spiral groove 102d on the outer wall of the outer tube 102a and the inner tube 102c drive the slider 103c and the rotating ring 103b to rotate in the fixed ring 103a. Because there is damping fluid between the rotating ring 103b and the fixed ring 103a, it is prevented that too much wire 104d is pulled out at one time. In addition, the two large rollers 104a can move synchronously during use, so that the wire 104d can be stably pulled out, so that the wire 104d has sufficient The length of the charging pile 101a is used to charge the vehicle. When charging is completed, the charging head 104e is placed in the placement groove 101f. At this time, the No. 1 spring 102e rebounds to drive the outer tube 102a and the inner tube 102c to expand and reset, so that the two large rollers 104a drive the wire 104d to expand and recover to the inside of the charging pile 101a. At the same time, during the resetting process of the outer tube 102a and the inner tube 102c, the No. 1 spiral groove 102b and the No. 2 spiral groove 102d will drive the slider 103c and the rotating ring 103b to rotate in the fixed ring 103a. At this time, because there is damping fluid between the fixed ring 103a and the rotating ring 103b, the wire 104d is prevented from being stored too quickly. When in use, the wire 104d can be pulled out for use. After use, it can be stored in a safe and effective way.

[0041] In summary, the expansion component 102 can drive the winding component 104 to store the cables, so that the cables can be pulled out of the charging pile component 101 for use and recycled after use. During recycling, the deceleration component 103 can slow down the storage speed of the cables by the expansion component 102 and the winding component 104 to prevent accidental injury to surrounding personnel during storage, thereby having a safe and effective cable storage function.

[0042] Example 2, reference Figures 1 to 10, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a limiting component 200 for the wire-receiving device of the charging pile, which solves the problem that the wire-receiving device continues to apply tension when the cable is pulled out for use. It includes: the ratchet assembly 201 includes a fixed block 201a fixed in the electric pile assembly 101, the fixed block 201a is located at a protrusion of the charging pile 101a in the electric pile assembly 101 corresponding to the convex groove 101c, and a movable block 201b sliding on the outer wall of the fixed block 201a, and also includes a fixed block 201b fixed to the movable block 201a. The second spring 201c is located inside the charging pile 101a in the charging pile assembly 101, and also includes a third spring 201d fixed in the movable block 201b, and also includes a pawl 201e sliding inside the movable block 201b corresponding to the end of the third spring 201d, and also includes a ratchet 201f adapted on the pawl 201e, the ratchet 201f is connected to the reduction assembly 103, and the ratchet 201f is fixed to the outer wall of the rotating ring 103b in the reduction assembly 103.

[0043] Specifically, the driving component 202 includes a protruding rod 202a that slides in the charging pile component 101, and the protruding rod 202a is located in the placement groove 101f in the charging pile component 101. The small end of the protruding rod 202a is provided with a vertical groove 202b, and a seesaw 202c that slides in the vertical groove 202b. The seesaw 202c is connected to the movable block 201b, and also includes a center rod 202d that slides on the outer wall of the seesaw 202c. The center rod 202d is connected to the charging pile component 101, and the center rod 202d rotates at the protrusion of the corresponding protruding groove 101c inside the charging pile 101a in the charging pile component 101.

[0044] The rest of the structure is the same as that of Example 1.

[0045] During use, when the charging head 104e is taken out from the placement slot 101f, the protruding rod 202a is separated from the resistance of the charging head 104e. At this time, the second spring 201c rebounds and drives the movable block 201b to move toward the ratchet 201f. The movable block 201b drives the seesaw 202c to move. Because the seesaw 202c slides in the center rod 202d, and the center rod 202d has a rotation function, when the seesaw 202c rotates around the center rod 202d, the other end of the seesaw 202c can resist the vertical slot 202b and drive the protruding rod 202a to the outside of the placement slot 101f. The movable block 201b will drive the pawl 201e to fit the ratchet 201f. In this state, the ratchet assembly 201 is in the open state. By pulling the wire 104d, the two large rollers 104a will be driven to move closer. The two large rollers 104a will drive the outer tube 102a and the inner tube 102c to move closer. At this time, the No. 1 spiral groove 102b and the No. 2 spiral groove 102d will drive the slider 103c and the rotating ring 103b to rotate. The rotating ring 103b can drive the ratchet 201f to rotate. The ratchet 201f can drive the pawl 201e to squeeze the No. 3 spring 201d and make the No. 3 spring 201 The elastic reset of d drives the pawl 201e to fit the ratchet 201f. At this time, if the length of the wire 104d is sufficient to charge the vehicle, the ratchet 201f and the pawl 201e can limit the rotating ring 103b and the slider 103c, so that the slider 103c is in the No. 1 spiral groove 102b and the No. 2 spiral groove 102d, so it can also prevent the No. 1 spring 102e from driving the outer tube 102a and the inner tube 102c to reset, thereby solving the problem that the expansion component 102 and the winding component 104 will continue to apply tension when the wire 104d is pulled out for use. When the wire 104d needs to be recovered, By inserting the charging head 104e into the placement groove 101f, the charging head 104e squeezes the protruding rod 202a, and the vertical groove 202b on the protruding rod 202a can drive the rocker 202c and the movable block 201b to reset to the fixed block 201a. The movable block 201b can drive the second spring 201c to be compressed. At the same time, the movable block 201b can drive the pawl 201e to disengage from the ratchet 201f. In this state, the ratchet assembly 201 is in a closed state. At this time, the deceleration assembly 103 disengages from the one-way limit, and the expansion assembly 102 can drive the winding assembly 104 to store the wire 104d.

[0046] In summary, when the main body 100 is in use, there will be no pulling force for restoring the cable after it is pulled out, and the cable can be restored only after use is completed.

[0047] Example 3, reference Figures 1 to 12, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a limiting component 300 for a wire-retracting device of a charging pile, which includes an elastic component 301 including a mounting block 301a fixed on the winding component 104, the mounting block 301a is the outer wall of the shaft of the rubber wheel 104b located in the winding component 104, and an extrusion rod 301b sliding on both sides of the inner wall of the mounting block 301a, and also includes a ball 301c arranged at the end of the extrusion rod 301b, and also includes a No. 4 spring 301d fixed between the two extrusion rods 301b.

[0048] Specifically, the track assembly 302 includes an adjustment shell 302a arranged on the outer wall of the mounting block 301a. The adjustment shell 302a is connected to the electric pile assembly 101. The adjustment shell 302a slides in the slide groove 101e in the electric pile assembly 101. Opposite spiral surfaces 302b are provided at both ends of the inner wall of the adjustment shell 302a. The spiral surface 302b is a spiral one-way guide surface.

[0049] Furthermore, the transmission assembly 303 includes a round rod 303a fixed to the bottom of the adjustment shell 302a, and a connecting block 303b arranged on the outer wall of the round rod 303a, the connecting block 303b is connected to the movable block 201b, and the connecting block 303b is provided with an inclined groove 303c at the round rod 303a.

[0050] The rest of the structure is the same as that of Example 2.

[0051] When in use, when the ratchet assembly 201 is in a closed state, the wire 104d will enter the charging pile 101a from the rubber wheel 104b and the combing wheel 104c. When the wire 104d enters the charging pile 101a, it will drive the rubber wheel 104b to rotate. The rubber wheel 104b can drive the elastic component 301 to rotate in the adjustment shell 302a. The corresponding ball 301c in the elastic component 301 will move on the left spiral surface 302b. Because the spiral surface 302b is spiral, the ball 301c will drive the extrusion rod 301b to squeeze the No. 4 spring 301d when moving. In this state, when the wire 104d is pulled to drive the rubber wheel 104b to rotate in the opposite direction, the rubber wheel 104b will drive the elastic component 30 1 rotates in the opposite direction, but the squeezing rod 301b at this time will be restricted by the spiral surface 302b, so the wire 104d cannot be pulled out in this state. When the ratchet assembly 201 enters the open state, the movable block 201b therein will drive the connecting block 303b to move, and the inclined groove 303c on the connecting block 303b can drive the round rod 303a and the adjusting shell 302a to move from the sliding groove 101e to the convex groove 101c. At this time, the opposite spiral surface 302b on the other side of the adjusting shell 302a will conflict with the corresponding ball 301c. Since the spiral surface 302b contacted by the ball 301c and the squeezing rod 301b at this time is opposite, the wire 104d can be pulled out in this state, but cannot be recovered into the charging pile 101a.

[0052] In summary, when the ball 301c moves from the highest point to the lowest point of the spiral surface 302b, the No. 4 spring 301d will drive the extrusion rod 301b and the ball 301c to approach the lowest point of the spiral surface 302b. There is a sound in this process, which has the function of reminding nearby people when the wire 104d is recovered. This sound can also be used to roughly estimate the length of the pulled-out wire 104d when the wire 104d is pulled out, and can make the wire 104d in a state where it can only be pulled out when in use, and in a state where it can only be recovered when the wire is reeled in. This function has the function of preventing the wire 104d from derailing on the winding assembly 104 to ensure the stable operation of the wire 104d.
