Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a balanced cable collector for charging pile cables. Background Art

[0002] With the continuous development and progress of science and technology, cars in society have changed from traditional gasoline cars to electric cars. As time goes by, the number of electric cars has been increasing. Electric cars only need to charge their batteries to start on the road. The conversion of electric energy does not produce pollution and has a good environmental protection effect.

[0003] The charging process of electric vehicles requires the use of charging piles. The number of charging piles on the market is also increasing, such as upright or wall-mounted charging piles, but their charging guns often have very long charging cables, so that the charging cables can extend to the charging port of the electric vehicle, making it convenient for the charging of the electric vehicle.

[0004] However, when the charging gun is pulled out, the pull rope at the upper end will also be pulled out. Its function is to pull the pull rope back through the internal spring after using the charging gun to prevent the cable from dragging on the ground and causing friction damage; however, when the user pulls out the charging gun, the pull rope will be pulled longer and longer, causing the user to use more and more pulling force, so that the spring mechanism needs greater force as it moves to the rear end.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0006] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a balanced cable collector for charging pile cables.

[0014] Preferably, at least one group of the spring winding mechanism is provided, and the spring winding mechanism is arranged at one side end of the mounting frame, and extends one end of the variable force spring toward the winding wheel.

[0015] As a preference, the spring winding mechanism is provided with four groups, and the four groups of spring winding mechanisms are respectively arranged at the two side ends of the mounting frame, and are installed at the inner end of the shell through the fixed shaft.

[0016] Preferably, the shell includes a bottom plate, a rear side plate, an upper outer shell and an inner mounting plate, the lower end of the inner mounting plate is fixed to the bottom plate, and one side end of the inner mounting plate is against the inner end surface of the rear side plate, thereby forming a chamber for placing the winding wheel and the spring winding mechanism therein, the winding wheel and the spring winding mechanism are both fixed to the inner mounting plate by a fixed shaft, and the upper outer shell is installed between the bottom plate and the rear side plate.

[0019] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0020] The utility model has a simple structure and is convenient and quick to use.

[0034] Reference Figure 1-5 As shown: A balanced cable reel for a charging pile cable, comprising a charging pile 300, a charging gun cable 200 and a cable reel 100 for retracting the cable 200, wherein the cable reel 100 comprises a housing 110 and a winding wheel 120, a spring winding mechanism 130 and a pull rope 140 for pulling the cable 200, by winding one end of the pull rope 140 around the winding wheel 120 and passing the other end through the housing 110 for the convenience of the user to stretch it, by arranging the spring winding mechanism at the rear end of the winding wheel 120, and controlling the winding wheel 120 to rotate and retract the pull rope 140 through the spring winding mechanism 130, so that the entire roll of the pull rope 140 is pulled out / reeled up.

[0035] In this embodiment, the spring winding mechanism 130 used includes a spring winding wheel 132 and a variable force spring 131. One end of the variable force spring 131 is clamped and wound on the spring winding wheel 132, and the other end is inserted into the winding wheel 120, so that the variable force spring 131 wound on the spring winding wheel 132 is stretched out and can be wound on the winding wheel 120 again, thereby reducing the tension required for the variable force spring 131.

[0036] Specifically, the force at one end of the variable force spring 131 used is greater than the force at the other end, and both ends of the variable force spring 131 always have an inward winding force, so that the variable force spring 131 is always wound into a roll. When one end of the variable force spring 131 is stretched a certain distance, its front end will flip inward and roll, so that the stretched variable force spring 131 will be rolled into a roll again.

[0037] In this embodiment, a fixed slot 133 is provided on the spring winding wheel 132, so that one end of the variable force spring 131 can be clamped therein and wound up, thereby achieving a good fixing and clamping effect, so that when the variable force spring 131 is stretched and rotated, it can drive the spring winding wheel 132 to rotate.

[0038] Specifically, an opening 121 is provided on the winding wheel 120 for receiving the other end of the variable force mainspring 131 therein, so that the variable force mainspring 131 can be rewound onto the winding wheel 120 after being pulled out for a certain distance.

[0039] In this embodiment, the spring winding mechanism 130 also includes a mounting frame 134 and a fixed shaft 135. The fixed shaft 135 is passed horizontally through the mounting frame 134 and is clamped on the inner end of the shell 110. The mounting frame 134 is also located at the center of the shell 110. Then, the center of the spring winding wheel 132 is passed through the fixed shaft 135 and movably mounted on the mounting frame 134 for rotation.

[0040] In this embodiment, at least one group of spring winding mechanisms 130 is provided. The spring winding mechanism 130 is arranged at one side end of the mounting frame 134 , and one end of the variable force spring 131 is extended toward the winding wheel 120 .

[0041] In actual use, four groups of spring winding mechanisms 130 are provided. The four groups of spring winding mechanisms 130 are respectively arranged at the two side ends of the mounting frame 134, and they are all installed at the inner end of the housing 110 through the fixed shaft 135, so as to achieve the rotation effect.

[0042] In this embodiment, the shell 110 includes a bottom plate 111, a rear side plate 112, an upper shell 113 and an inner mounting plate 114. The lower end of the inner mounting plate 114 is fixed on the bottom plate 111, and one side end of the inner mounting plate 114 is abutted against the inner end surface of the rear side plate 112, so that the three form a chamber for the winding wheel 120 and the spring winding mechanism 130 to be placed therein. Specifically, the winding wheel 120 and the spring winding mechanism 130 are both fixed on the inner mounting plate 114 by a fixed shaft 135, and then the upper shell 113 is assembled and mounted on the bottom plate 111 and the upper end of the rear side plate 112, so as to form a complete inner chamber of the shell 110.

[0043] In this embodiment, a winding groove 122 which is recessed inward and for winding the pull rope 140 is provided in the central area of ​​the winding wheel 120. A limiting groove 123 for limiting rotation is provided on the side end of the winding wheel 120, and a limiting movable column 124 is provided on the outer end of the inner mounting plate 114. By clamping the limiting movable column 124 in the limiting groove 123 for position limitation, the pull rope 140 can be prevented from continuing to be wound up, thereby achieving a function of stopping the stretching.

[0044] In this embodiment, a clamping member 400 is further provided at one end of the pull rope 140. By clamping and fixing the clamping member 400 on the cable 200, the pull rope 140 can pull the cable 200 during the winding and recovery process, thereby preventing the cable 200 from rubbing against the ground and causing wear and damage to the cable sheath.
