[0039] In the following, in conjunction with all the drawings in the specification, a wire take-up device 10 for a charging pile 100 provided in an embodiment of the present application is described in detail through a specific embodiment.

[0040] Please refer to Figure 1One embodiment of the utility model discloses a charging pile 100, including a wire take-up device 10, a main body 20, a gun wire 30 and a charging gun 40.

[0041] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the wire take-up device 10 includes a mounting frame 11, a wire drum 12, a first guide wheel 13, a guide assembly 14, a wire clamp 15, and a wire rope 17. The wire drum 12 is rotatably connected to the mounting frame 11, the first guide wheel 13 is rotatably connected to the mounting frame 11, the guide assembly 14 is installed on the mounting frame 11, the guide assembly 14 is provided with a guide cavity 1402, and the wire clamp 15 is used for passing the gun line 30. One end of the wire rope 17 is wound around the wire drum 12, and the other end of the wire rope 17 passes through the first guide wheel 13 and the guide assembly 14 in sequence, and is connected to the wire clamp 15, the wire rope 17 abuts against the circumferential side surface of the first guide wheel 13, and the wire rope 17 passes through the guide cavity 1402.

[0042] The wire clamp 15 clamps the gun wire 30, raises the height of the gun wire 30, and reduces the risk of the gun wire 30 dragging and rubbing on the ground. One end of the gun wire 30 is connected to the charging gun 40. When the charging gun 40 is located at different positions relative to the mounting frame 11, the gun wire 30 is in different bending states, and thus the wire clamp 15 is at different heights.

[0043] Through the above structure, when the wire drum 12 rotates, the wire rope 17 is extended and retracted relative to the mounting frame 11, and the wire rope 17 presses against the first guide wheel 13 and drives the first guide wheel 13 to rotate, thereby generating rolling friction between the wire rope 17 and the first guide wheel 13, thereby reducing the wear of the wire rope 17 when it is extended and retracted relative to the mounting frame 11.

[0044] In addition, the wire rope 17 passes through the guide cavity 1402, and when a section of the wire rope 17 between the guide assembly 14 and the wire clamp 15 tilts, the cavity wall of the guide cavity 1402 abuts against the wire rope 17, so that a section of the wire rope 17 between the first guide wheel 13 and the guide assembly 14 will not tilt, and the wire rope 17 can stably press against the first guide wheel 13 to prevent the wire rope 17 from detaching from the first guide wheel 13.

[0045] Specifically, in this embodiment, the accommodating cavity 1102 includes a first chamber 1104 and two second chambers 1106. The two second chambers 1106 are respectively located on both sides of the first chamber 1104. The first chamber 1104 and the second chamber 1106 are both rectangular parallelepipeds. In a top view, a long side of the top surface of the first chamber 1104 is collinear with a long side of the top surface of the second chamber 1106, and the length of the wide side of the top surface of the first chamber 1104 is greater than the length of the wide side of the top surface of the second chamber 1106.

[0046] The mounting frame 11 includes a bottom plate 114 and a side plate 116, the side plate 116 is connected to the side of the bottom plate 114, and the side plate 116 encloses a receiving cavity 1102. The number of the wire drum 12, the first guide wheel 13 and the guide assembly 14 are two, and the wire drum 12 and the first guide wheel 13 are both located in the receiving cavity 1102. The two wire drums 12 are both located in the middle of the receiving cavity 1102, and the two first guide wheels 13 are respectively located on both sides of the receiving cavity 1102.

[0047] The wire reel 12 is driven by a motor. The wire clamp 15 is similar to a triangular prism, and includes an abutting end face 152, which is located at a top corner of the wire clamp 15. When the wire rope 17 extends to a minimum length relative to the mounting frame 11, the abutting end face 152 abuts against the guide assembly 14, so that the wire clamp 15 does not shake relative to the guide assembly 14. The wire clamp 15 is provided with a wire clamping cavity 1502, one end of which passes through a bottom corner of the wire clamp 15, and the other end of the wire clamping cavity 1502 passes through another bottom corner of the wire clamp 15, and the gun line 30 can be inserted into the wire clamping cavity 1502. The wire rope 17 is made of a flexible material.

[0048] In other embodiments, the number of the wire drum 12, the first guide wheel 13 and the guide assembly 14 can also be other, such as one or three. The support frame 117 can also be other structures, such as a hollow cuboid. The guide assembly 14 can also be other structures, for example, the guide assembly 14 is a block as a whole, the guide cavity 1402 is a cylindrical structure, and both ends of the cavity wall of the guide cavity 1402 are provided with rounded corners.

[0049] In some embodiments, the mounting frame 11 includes a support frame 117, the guide assembly 14 is installed in the support frame 117, the support frame 117 is provided with a clearance groove 1172, the first guide wheel 13 is partially inserted into the clearance groove 1172, and one side of the first guide wheel 13 is aligned with the guide cavity 1402.

[0050] Through the above structure, the support frame 117 is used for the installation of the guide assembly 14, and the first guide wheel 13 extends into the support frame 117 through the clearance groove 1172, so that one side of the first guide wheel 13 is aligned with the guide cavity 1402, so that the part of the rope 17 between the first guide wheel 13 and the guide assembly 13 is difficult to rub against the support frame 117.

[0051] Specifically, the mounting frame 11 includes two support frames 117, and the support frames 117 are hollow rectangular structures. The two support frames 117 are installed on both sides of the bottom plate 114, and each guide assembly 14 is installed on a corresponding support frame 117. The guide assembly 14 includes two guide wheels that fit each other, and the circumferential side surfaces of the two guide wheels are respectively provided with annular grooves, and the annular grooves on the two guide wheels together form a guide cavity 1402. In the horizontal direction, the wire drum 12 and the first guide wheel 13 are arranged in sequence. In the vertical direction, the first guide wheel 13 and the guide assembly 14 are arranged in sequence from top to bottom. The support frame 117 is provided with a clearance groove 1172, and the first guide wheel 13 is partially penetrated in the clearance groove 1172, so that one side of the first guide wheel 13 is aligned with the guide cavity 1402.

[0052] In some embodiments, a first annular groove 1302 is formed on the circumferential side surface of the first guide wheel 13 , and the first annular groove 1302 surrounds the rotation axis of the first guide wheel 13 . The rope 17 is partially placed in the first annular groove 1302 , and the rope 17 abuts against the groove wall of the first annular groove 1302 .

[0053] Through the above structure, one end of the rope 17 is connected to the wire clamp 15. Under the action of the gravity of the wire clamp 15, the rope 17 can abut against the groove wall of the first annular groove 1302, and then the rope 17 can be stably placed in the first annular groove 1302. The groove wall of the first annular groove 1302 limits the rope 17, so that the rope 17 will not fall off the first guide wheel 13.

[0054] Specifically, in this embodiment, the first annular groove 1302 is a semicircular ring, so that the cord 17 has a larger contact area with the groove wall of the first annular groove 1302, further reducing the wear of the cord 17. In other embodiments, the cross section of the first annular groove 1302 can also be other shapes, such as a rectangle.

[0055] Please refer to Figure 5 and Figure 6 In some embodiments, the mounting frame 11 includes a limiting bracket 112, the limiting bracket 112 includes a limiting wall 1122 and two supporting walls 1124, one side of the limiting wall 1122 is connected to one supporting wall 1124, the other side of the limiting wall 1122 is connected to the other supporting wall 1124, the first guide wheel 13 is located between the two supporting walls 1124, one end of the rotating shaft of the first guide wheel 13 is rotatably connected to one supporting wall 1124, the other end of the rotating shaft of the first guide wheel 13 is rotatably connected to the other supporting wall 1124, and the rope 17 is located between the first guide wheel 13 and the limiting wall 1122.

[0056] Through the above structure, during the assembly process of the mounting frame 11 , the limiting bracket 112 and the first guide wheel 13 can be pre-installed first, and then the limiting bracket 112 and the first guide wheel 13 can be installed in the accommodating cavity 1102 , saving the assembly time of the mounting frame 11 .

[0057] In addition, the wire rope 17 is located between the groove wall of the first annular groove 1302 and the limiting wall 1122, so that the limiting wall 1122 has a limiting effect on the wire rope 17, and the first guide wheel 13 prevents the wire rope 17 from floating away from the first annular groove 1302 during rotation.

[0058] Specifically, in this embodiment, the limiting wall 1122 and the supporting wall 1124 are both rectangular sheet structures, one side of the supporting wall 1124 is connected to the bottom plate 114, and the other opposite side of the supporting wall 1124 is connected to the limiting wall 1122, and one of the supporting walls 1124 is in contact with the side plate 116.

[0059] In other embodiments, the limiting wall 1122 and the supporting wall 1124 may be other structures, for example, the limiting wall 1122 and the supporting wall 1124 may be regular hexagons.

[0060] In some embodiments, the guide assembly 14 includes two second guide wheels 142 , both of which are rotatably connected to the mounting frame 11 , the rotation axes of the two second guide wheels 142 are parallel to each other, and the guide cavity 1402 is disposed between the two second guide wheels 142 .

[0061] Through the above structure, when the rope 17 is extended or retracted relative to the mounting frame 11, the rope 17 can abut against the side surface of the second guide wheel 142, and then the second guide wheel 142 rolls, so that rolling friction is generated between the second guide wheel 142 and the rope 17, thereby reducing the wear of the rope 17 when it is extended or retracted relative to the mounting frame 11.

[0062] Specifically, the rotation axes of the two second guide wheels 142 are located at the same height, and the two second guide wheels 142 have the same structure.

[0063] In some embodiments, the rotation axis of each second guide wheel 142 is perpendicular to the rotation axis of the first guide wheel 13, the arrangement direction of the two second guide wheels 142 is parallel to the rotation axis of the first guide wheel 13, and the part of the rope 17 between the wire drum 12 and the first guide wheel 13 is perpendicular to the part of the rope 17 between the first guide wheel 13 and the guide cavity 1402.

[0064] Through the above structure, the direction from the wire drum 12 to the first guide wheel 13 is parallel to the horizontal direction, and the direction from the first guide wheel 13 to the guide cavity 1402 is parallel to the vertical direction, so that the wire rope 17 is bent 90° at the first guide wheel 13, and the wire rope 17 and the first guide wheel 13 have a larger contact area, and then under the action of gravity of the wire clamp 15, the abutment relationship between the wire rope 17 and the first guide wheel 13 is more stable.

[0065] In addition, the arrangement direction of the two second guide wheels 142 is parallel to the horizontal direction, so that when the wire rope 17 extends to the minimum length relative to the mounting frame 11, the abutting end surface 152 of the wire clamp 15 can abut against the side surfaces of the two second guide wheels 142 at the same time.

[0066] Specifically, in this embodiment, the first guide wheel 13 has the same structure as the second guide wheel 142, and the first guide wheel 13 is made of a rigid material as a whole. In other embodiments, the rotation axis of the first guide wheel 13 is made of a rigid material, and the circumferential outer side of the first guide wheel 13 is made of a flexible material, such as rubber, thereby increasing the maximum static friction between the wire rope 17 and the groove wall of the first annular groove 1302, reducing the possibility of the wire rope 17 slipping relative to the groove wall of the first annular groove 1302, and making the friction between the wire rope 17 and the groove wall of the first annular groove 1302 stably rolling friction.

[0067] In some embodiments, a second annular groove 1422 is provided on the axial side surface of each second guide wheel 142, the cross-section of the second annular groove 1422 is semicircular, the circumferential side surfaces of the two second guide wheels 142 are in contact with each other, and from the perspective of the first guide wheel 13 to the guide cavity 1402, the guide cavity 1402 is circular.

[0068] Through the above structure, the guide cavity 1402 is formed between the groove walls of the two second annular grooves 1422. When the wire rope 17 is extended and retracted relative to the mounting frame 11, the two second guide wheels 142 rotate, and the guide cavity 1402 can be stably maintained. The groove walls of the two second annular grooves 1422 both limit the wire rope 17, so that the wire rope 17 will not escape from the guide cavity 1402.

[0069] In addition, from the perspective of the first guide wheel 13 to the guide cavity 1402, the guide cavity 1402 is circular, and the shape of the guide cavity 1402 can be adapted to the cross-sectional shape of the wire rope 17, so that the wire rope 17 is not easy to shake in the guide cavity 1402, and then the clamp 15 is not easy to shake relative to the mounting frame 11, and the clamp 15 can clamp the gun line 30 more stably. In addition, the groove wall of the second annular groove 1422 has a larger contact area with the wire rope 17, further reducing the wear of the wire rope 17.

[0070] Specifically, in the present embodiment, the second annular groove 1422 is a circular ring with a semicircular cross section. In other embodiments, the cross section of the second annular groove 1422 may also be other shapes, such as a rectangle.

[0071] Please refer to Figure 1 and Figure 2 In some embodiments, the wire take-up device 10 further includes a driving component 16 , which is mounted on the mounting frame 11 , and is used to drive the wire drum 12 to rotate relative to the mounting frame 11 .

[0072] Through the above structure, when the driving component 16 drives the wire drum 12 to rotate, the wire rope 17 wrapped around the wire drum 12 can be output or input relative to the wire rope 17, and then the wire rope 17 can extend out or extend into the mounting frame 11.

[0073] Specifically, the driving component 16 is a motor. There are two driving components 16 . Each driving component 16 corresponds to a wire drum 12 . The driving component 16 is installed on the bottom plate 114 .

[0074] In some embodiments, the wire clamp 15 moves in a direction away from the mounting frame 11 , pulling the wire rope 17 out of the mounting frame 11 , and driving the wire drum 12 to rotate along the first rotation direction.

[0075] Through the above structure, when the user needs to pull out the cord 17, he only needs to pull the charging gun 40, so that the gun line 30 drives the wire clamp 15, the wire clamp 15 pulls the cord 17, and the cord 17 drives the wire reel 12 to rotate along the first rotation direction. The cord 17 extends out of the mounting bracket 11, so that the user can charge the device more conveniently.

[0076] In some embodiments, the wire take-up device 10 further includes a control panel 50, which is mounted on the mounting frame 11. The control panel 50 is electrically connected to the driving component 16, and the control panel 50 is used to receive an electrical signal from the charging gun 40, and control the driving component 16 to rotate or stop rotating in the second rotation direction according to the electrical signal. When the driving component 16 rotates in the second rotation direction, the driving wire drum 12 rotates in the second rotation direction, and the wire rope 17 retracts relative to the mounting frame 11.

[0077] Through the above structure, when the user needs to charge the device to be charged, the user pulls the gun line 30, the rope 17 extends relative to the mounting frame 11, and the clamp 15 moves downward. When the clamp 15 moves to an appropriate height, the charging gun 40 is electrically connected to the device to be charged, the charging gun 40 sends an electrical signal to the control board 50, the control board 50 controls the driving component 16 to stop rotating, and the clamp 15 clamps the gun line 30, so that the gun line 30 does not contact the ground, reducing the wear of the gun line 30. When the charging gun 40 completes charging, the user pulls the charging gun 40 out of the device, the charging gun 40 sends an electrical signal to the control board 50, the control board 50 controls the driving component 16 to rotate in the second rotation direction, and the rope 17 retracts relative to the mounting frame 11 until the abutting end face 152 of the clamp 15 abuts against the guide assembly 14. The first rotation direction is opposite to the second rotation direction.

[0078] Specifically, the control board 50 is an integrated circuit board, and a signal transmitter may be installed in the charging gun 40 . When the charging gun 40 is in different states, the signal transmitter can transmit different electrical signals to the control board 50 .

[0079] Please refer to Figure 1 One embodiment of the utility model discloses a charging pile 100, including a main body 20, a gun line 30, a charging gun 40 and a wire take-up device 10 in any of the above embodiments, a mounting frame 11 is installed on the main body 20, the gun line 30 is passed through the wire clamp 15, one end of the gun line 30 is electrically connected to the main body 20, and the other end of the gun line 30 is electrically connected to the charging gun 40, and the charging gun 40 is detachably connected to the main body 20.

[0080] Through the above structure, when the user needs to charge the device, the charging gun 40 is disassembled relative to the main body 20, and then the charging gun 40 is pulled, and the motor drives the cable drum 12 to rotate along the first rotation direction, so that the cable clamp 15 moves downward, and then the charging gun 40 is electrically connected to the device to be charged, and the cable clamp 15 clamps the gun line 30 so that the gun line 30 does not fall to the ground.
