The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0043] The following will describe in detail a wire winding device 100 provided in an embodiment of the present application with reference to all the drawings of the specification through specific embodiments.

[0044] Please refer to Figure 1 In one embodiment of the present utility model, a charging pile 1000 is disclosed, which includes a wire winding device 100, a main body 200, a gun line 300 and a gun head.

[0045] The main body 200 includes a housing, a charging controller, a fan and a power module, etc. The fan is used to dissipate heat from components such as the charging controller and the power module. The power module distributes electric energy to the corresponding gun head through the gun line 300, and then the gun head can charge a new energy vehicle.

[0046] Please refer to Figures 2 to 4In some embodiments, the wire taking-up device 100 includes a driving component 20, a wire drum 22, a first guide component 40, a wire rope 50 and a wire clamp 60; the wire drum 22 is installed on the rotating shaft of the driving component 20; the control component 30 includes a pressure sensor 32 and a control circuit board 34, the pressure sensor 32 is electrically connected to the control circuit board 34, the control circuit board 34 is electrically connected to the driving component 20, and the control circuit board 34 can control the driving component 20 to rotate in a clockwise direction or a counterclockwise direction; the first guide component 40 is located above the pressure sensor 32 and presses the pressure sensor 32, and the first guide component 40 is provided with a first guide cavity 4402; the wire rope 50 is wound around the wire drum 22, the wire rope 50 is passed through the first guide cavity 4402 and presses downwardly against the first guide component 40, and the end of the wire rope 50 away from the driving component 20 extends out of the first guide component 40; the wire clamp 60 is installed at the end of the wire rope 50 away from the driving component 20.

[0047] The wire take-up device 100 may further include a mounting frame 10 , and the driving assembly 20 , the control assembly 30 and the first guide assembly 40 are all mounted on the mounting frame 10 .

[0048] Through the above structure, under normal circumstances, when the charging pile 1000 is not in use, the gun head is inserted into the main body 200. At this time, under the action of the gravity of the gun line 300, the gun line 300 pulls the wire clamp 60, and the wire clamp 60 drives the rope 50 to press against the first guide assembly 40. The pressure sensor 32 receives the pressure of the first guide assembly 40. At this time, the pressure sensor 32 transmits an electrical signal to the control circuit board 34, and the control circuit board 34 controls the drive assembly 20 to stop rotating.

[0049] When the user needs to charge the new energy vehicle, the user removes the gun head from the main body 200, and then applies force to the gun head, so that the gun head pulls the gun line 300, and the tension of the gun line 300 on the clamp 60 increases, and the tension of the clamp 60 on the line 50 also increases, and the pressure of the line 50 on the first guide assembly 40 increases, so that the pressure of the first guide assembly 40 on the pressure sensor 32 increases, and the pressure sensor 32 transmits an electrical signal to the control circuit board 34, and the control circuit board 34 controls the drive assembly 20 to rotate in a preset clockwise direction, and the wire drum 22 rotates and releases the line 50, and the length of the line 50 extending out of the first guide assembly 40 increases, and the height of the clamp 60 decreases, so that the gun head can contact the new energy vehicle. In this embodiment, when the user pulls the gun head, the line 50 can apply an upward pulling force to the gun line to balance the gravity of the gun line, so that the user can save more effort when pulling the gun head.

[0050] When the charging of the new energy vehicle is completed and the user needs to reset the wire clamp 60, only need to lift the gun wire 300 upward. The pulling force of the gun wire 300 on the wire clamp 60 decreases, the pulling force of the wire clamp 60 on the wire rope 50 also decreases, and the pressure of the wire rope 50 on the first guiding component 40 decreases, so that the pressure of the first guiding component 40 on the pressure sensor 32 decreases. The pressure sensor 32 transmits an electrical signal to the control circuit board 34, and the control circuit board 34 controls the driving component 20 to rotate in a preset counterclockwise direction. The wire reel 22 rotates and retracts the wire rope 50, the length of the wire rope 50 extending out of the first guiding component 40 decreases, and the height of the wire clamp 60 increases, so that the wire clamp 60 is reset. Furthermore, in this embodiment, when the user puts the gun head back into the main body 200, the wire rope 50 can apply an upward pulling force to the gun wire to balance the gravity of the gun wire, so that it is more labor-saving for the user to put the gun head back into the main body 200.

[0051] Specifically, in this embodiment, the wire clamp 60 clamps the gun wire 300. The main body 200 has a cuboid structure, and the charging pile 1000 includes two wire winding devices 100. The mounting frame 10 is installed on the main body 200, the mounting frame 10 is located above the main body 200, and the mounting frame 10 has a bracket structure similar to a rectangle.

[0052] The driving component 20 is a motor, and the driving component 20 further includes a limit magnet 24. The limit magnet 24 is located on one side of the driving component 20; when the rotating shaft of the driving component 20 stops rotating, the limit magnet 24 detects the angular position of the rotating shaft of the driving component 20 through magnetic field induction. When a certain part of the rotating shaft of the driving component 20 approaches the limit magnet 24, the limit magnet 24 will sense the change of the magnetic field and trigger the limit. The limit magnet 24 can provide mechanical limit for the rotating shaft of the driving component 20 to avoid the driving component 20 from being blocked.

[0053] The driving component 20 is located on one side of the mounting frame 10 close to the center position of the top of the main body 200, the control component 30 is located on the side of the mounting frame 10 away from the center position of the top of the main body 200, the pressure sensor 32 is installed at the bottom of the mounting frame 10, the control circuit board 34 is mounted on the top of the mounting frame 10, the control circuit board 34 is parallel to the horizontal plane, and the first guiding component 40 is located between the control circuit board 34 and the pressure sensor 32; the control component 30 further includes a signal amplifier 36. The signal amplifier 36 is electrically connected between the pressure sensor 32 and the control circuit board 34. The signal amplifier 36 is used to amplify the electrical signal of the pressure sensor 32, and the signal amplifier 36 is installed on the mounting frame 10 and is located on one side of the first guiding component 40.

[0054] The first guiding component 40 includes a roller structure. A first guiding cavity 4402 is formed in the circumferential side wall of the roller structure. The wire rope 50 is wound around the wire reel 22, and the part of the wire rope 50 passing through the first guiding cavity 4402 is located above the roller structure. Thus, the wire rope 50 can press against the cavity wall of the first guiding cavity 4402 to transfer the pressure to the pressure sensor 32 through the roller structure.

[0055] In other embodiments, the main body 200 may also have other structures, such as a cylinder; the charging pile 1000 may also include other numbers of wire winding devices 100, such as one or three; the mounting bracket 10 may also be of other structures, such as a frame structure similar to a cylinder; the control circuit board 34 may also be located on one side of the mounting bracket 10, and the control circuit board 34 may also be perpendicular to the horizontal plane; the first guiding component 40 may also be of other structures, such as a block-shaped guiding structure mounted on the top of the pressure sensor 32, and a sliding friction is generated between the wire rope 50 and the first guiding component 40.

[0056] In some embodiments, the first guiding component 40 includes a first bracket 42 and a first guiding wheel 44. The first bracket 42 is mounted above the pressure sensor 32 and presses against the pressure sensor 32. The first guiding wheel 44 is rotatably connected to the first bracket 42. The rotation axis of the first guiding wheel 44 is parallel to the horizontal plane. The first guiding cavity 4402 is formed in the circumferential side wall of the first guiding wheel 44. The first guiding cavity 4402 is arranged around the rotation axis of the first guiding wheel 44. The wire rope 50 passes through the first guiding cavity 4402 and presses downward against the first guiding wheel 44.

[0057] With the above structure, when the wire rope 50 extends or retracts relative to the mounting bracket 10, the wire rope 50 can drive the first guiding wheel 44 to roll, so as to reduce the friction between the wire rope 50 and the first guiding wheel 44 and improve the service life of the wire rope 50.

[0058] In addition, when the wire rope 50 drives the first guiding wheel 44 to roll, the wire rope 50 will not vibrate due to sliding friction with the cavity wall of the first guiding cavity 4402, thereby reducing the possibility of the wire rope 50 falling off relative to the first guiding cavity 4402 and improving the stability of the wire rope 50 during operation.

[0059] Specifically, in this embodiment, the first bracket 42 is a "U"-shaped structure formed by bending a sheet metal, and the bottom of the first bracket 42 is fixed to the upper end of the pressure sensor 32. The first guiding wheel 44 is in a cylindrical roller structure, the first guiding cavity 4402 is in an annular structure, and the bottom cavity wall of the first guiding cavity 4402 is in an arc structure.

[0060] In other embodiments, the first bracket 42 may also be of other structures, such as a frame structure; the cross-section of the first guiding cavity 4402 may also be of other shapes, such as a rectangle.

[0061] Please refer to Figures 4 to 6 , in some embodiments, the wire take-up device 100 further includes a mounting frame 10, and a driving assembly 20, a control assembly 30, and a first guiding assembly 40 are mounted on the mounting frame 10. The first guiding assembly 40 further includes a second bracket 46, the second bracket 46 is mounted on the mounting frame 10, the first bracket 42 includes two side plates 424, the second bracket 46 is located between the two side plates 424, the second bracket 46 includes two mounting plates 462, and the first guiding wheel 44 is located between the two mounting plates 462; the first guiding wheel 44 includes a first rotating shaft 442, one end of the first rotating shaft 442 penetrates through one mounting plate 462 and is rotatably connected to one side plate 424, and the other opposite end of the first rotating shaft 442 penetrates through the other mounting plate 462 and is rotatably connected to the other side plate 424.

[0062] With the above structure, the second bracket 46 is mounted on the mounting frame 10. The two mounting plates 462 of the second bracket 46 play a lateral limiting role on the first guiding wheel 44. At the same time, the mounting plates 462 play a lateral supporting role on the adjacent side plates 424, reducing the shaking degree of the first bracket 42 and the first guiding wheel 44 during the working process, so as to improve the stability of the wire take-up device 100 in this embodiment.

[0063] Specifically, the first bracket 42 further includes a bottom plate 422, the bottom plate 422 is parallel to the horizontal plane and is fixed to the upper end of the pressure sensor 32, the two side plates 424 are both perpendicular to the horizontal plane, and the two side plates 424 are respectively connected to the opposite sides of the bottom plate 422. The side plates 424 protrude upward relative to the bottom plate 422. The first guiding wheel 44 is rotatably connected between the two side plates 424 through the first rotating shaft 442, and the first guiding wheel 44 is located at the upper part of the first bracket 42.

[0064] The mounting plate 462 has a sheet-shaped sheet metal structure. The mounting plate 462 includes a footrest 4622, the footrest is connected to the mounting frame 10 by screws, and a waist-shaped hole 4602 for the first rotating shaft 442 to pass through is formed in the mounting plate 462. The long axis of the waist-shaped hole 4602 is perpendicular to the horizontal plane, and the short axis of the waist-shaped hole 4602 is parallel to the horizontal plane.

[0065] In some embodiments, the first guiding assembly 40 further includes two second guiding wheels 48, the two second guiding wheels 48 are rotatably connected between the two mounting plates 462, the rotation axes of the two second guiding wheels 48 are both parallel to the rotation axis of the first guiding wheel 44, and the first guiding wheel 44 is located between the two second guiding wheels 48.

[0066] A second guiding cavity 4802 is formed in the circumferential side wall of the second guiding wheel 48. The second guiding cavity 4802 is arranged around the rotation axis of the second guiding wheel 48. The wire rope 50 is threaded between the first guiding wheel 44 and the second guiding wheel 48. The wire rope 50 passes through the second guiding cavity 4802 and presses against the second guiding wheel 48 upward.

[0067] With the above structure, the first guiding wheel 44 is located between two second guiding wheels 48. The wire rope 50 abuts against the inner wall of the second guiding cavity 4802. Thus, the second guiding wheel 48 can guide the wire rope 50, so that the part of the wire rope 50 located in the first guiding cavity 4402 is in a stable inverted "U" shape, increasing the contact area between the wire rope 50 and the inner wall of the first guiding cavity 4402, and the wire rope 50 can be stably embedded in the first guiding cavity 4402.

[0068] Specifically, in this embodiment, the two second guiding wheels 48 are at the same height, and in the direction perpendicular to the rotation axis of the second guiding wheel 48, the two second guiding wheels 48 are arranged in sequence. The height of the first guiding wheel 44 is higher than that of the second guiding wheel 48.

[0069] In other embodiments, the first guiding wheel 44 and the two second guiding wheels 48 can also be at the same height.

[0070] Please refer to Figure 7 , in some embodiments, the wire winding device 100 further includes a second guiding assembly 70. The second guiding assembly 70 includes a third support 72 and a third guiding wheel 74. The third support 72 is installed on the mounting frame 10. The third guiding wheel 74 is rotatably connected to the third support 72. The rotation axis of the third guiding wheel 74 is perpendicular to the horizontal plane. A third guiding cavity 7402 is formed in the circumferential side wall of the third guiding wheel 74. The third guiding cavity 7402 is arranged around the rotation axis of the third guiding wheel 74.

[0071] The wire rope 50 passes through the third guiding cavity 7402 and presses against the third guiding wheel 74. The part of the wire rope 50 extending out of the third guiding cavity 7402 faces the second guiding cavity 4802. The part of the wire rope 50 extending out of the wire reel 22 passes through the third guiding cavity 7402, a second guiding cavity 4802, the first guiding cavity 4402, and another second guiding cavity 4802 in sequence.

[0072] With the above structure, the rotation axis of the wire reel 22 is parallel to the horizontal plane. Horizontally, the wire reel 22 has a certain width. Within the width range of the wire reel 22, the wire rope 50 can extend from different width positions of the wire reel 22, resulting in the wire rope 50 not necessarily facing the second guiding cavity 4802 when extending. The third guiding wheel 74 guides the wire rope 50, making the part of the wire rope 50 extending out of the third guiding cavity 7402 face the second guiding cavity 4802. Further, in the direction of the rotation axis of the second guiding wheel 48, the wire rope 50 will not sway relative to the second guiding wheel 48; during the telescopic process of the wire rope 50, the part of the wire rope 50 placed in the first guiding assembly 40 can be more stable.

[0073] Specifically, the size and shape of the third guiding wheel 74 are the same as those of the second guiding wheel 48.

[0074] And in this embodiment, from a top view, the second guiding assembly 70 is located between the wire reel 22 and the first guiding assembly 40. In other embodiments, the wire reel 22, the first guiding assembly 40, and the second guiding assembly 70 can also have other positional relationships. For example, the connection line from the wire reel 22 to the second guiding assembly 70 is perpendicular to the connection line from the second guiding assembly 70 to the first guiding assembly 40, and the rotation axis of the first guiding wheel 44 is perpendicular to the rotation axis of the wire reel 22.

[0077] With the above structure, the wire rope 50 passes between the third guiding wheel 74 and the fourth guiding wheel 76, so that the part of the wire rope 50 placed in the second guiding assembly 70 can be more stable, and the wire rope 50 will not fall off relative to the second guiding assembly 70.

[0078] Specifically, in the present embodiment, there are two fourth guide wheels 76, and the portion of the wire rope 50 extending out of the wire drum 22 is first passed between the two fourth guide wheels 76, and then passed through the third guide cavity 7402; and in the horizontal direction, the two fourth guide wheels 76 are both located between the wire drum 22 and the third guide wheel 74, and the direction from the wire drum 22 to the second guide assembly 70 is perpendicular to the arrangement direction of the two fourth guide wheels 76; the third guide wheel 74 and the two fourth guide wheels 76 are all located at the same height.

[0079] In other embodiments, the number of the fourth guide wheels 76 may be other numbers, such as one or three.

[0086] Through the above structure, the guide rod assembly 90 guides the rope 50. In the horizontal direction, the rope 50 extends out of the side guide hole 9404 and is at a certain distance from the mounting frame 10, thereby preventing the rope 50 from contacting the mounting frame 10 during shaking and causing wear of the rope 50.

[0087] In addition, the rotating rod 94 is rotatably connected to the mounting base 92. When the user pulls or lifts the gun line 300, the gun line 300 may cause the wire clamp 60 to shake, and the wire clamp 60 drives the wire rope 50 to shake. The wire rope 50 drives the rotating rod 94 to rotate during the shaking process; and then the rotating rod 94 has a buffering effect on the shaking wire rope 50 to prevent the wire rope 50 from repeatedly rubbing against the guide rod assembly 90 during the shaking process and causing wear.

[0089] Two guide rollers 942 close to each other are also provided in the second installation cavity 9402. The structure of the guide roller 942 is the same as that of the first guide wheel 44. The guide roller 942 is rotatably connected to the cavity wall of the second installation cavity 9402. The two guide rollers 942 are located in the same horizontal plane, and the rope 50 is passed between the two guide rollers 942.
