charging piles

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 29, 2024, with application number 202420633502.7 and invention name “Charging Pile”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of gun line management of charging piles, and more specifically, to a charging pile. Background Art

[0003] A charging pile is a device that provides power replenishment for mobile electrical devices such as electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and installed in public buildings (such as charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of mobile electrical devices according to the adjusted voltage and current.

[0004] Charging piles draw high currents, and the cables they use are thick and heavy. These cables can slide against the ground during use, causing severe wear and tear, posing safety risks and increasing maintenance costs. To address this issue, existing technologies typically install a balancer on the charging pile to suspend the cables. Users simply drag the suspended cables to a mobile power device, preventing friction between the cables and the ground.

[0005] However, the longer the gun line is stretched, the greater the rebound force generated by the balancer, which makes it more difficult for the user to pull the gun line and inconvenient to use.

[0006] Therefore, how to make the gun line of the charging pile more labor-saving when dragging it to a long distance is a problem that needs to be solved urgently by those skilled in the art.

DETAILED DESCRIPTION

[0035] The embodiment of the present application discloses a charging pile, in which a counterweight is connected to a gun line through a traction rope wound around a pulley assembly, so that the gravity of the gun line is balanced by the gravity of the counterweight, ensuring that the force exerted by the traction rope on the gun line remains unchanged when the gun is dragged, avoiding the situation where the user encounters greater resistance when dragging the gun line for a longer distance, making it easier for the user to drag the gun line to a long distance and convenient for the user to use.

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] In this application, the words indicating directions, such as "upper", "lower", "top", "vertical direction", etc., refer to the directions of the charging pile when it is in normal use.

[0038] Please refer to Figures 1 to 5. An embodiment of the present application provides a charging pile, including a shell 112, a counterweight 109, a pulley group and a traction rope 113; the shell 112 is provided with a wire outlet hole; the counterweight 109 is arranged in the shell 112, and the counterweight 109 can move in the vertical direction; the pulley group includes a movable pulley 108 installed on the counterweight 109 and a fixed pulley 104 installed on the top of the shell 112; the first end of the traction rope 113 is fixed to the top of the shell 112, and the second end passes through the movable pulley 108 and the fixed pulley 104 in sequence, then extends out of the shell 112 and is connected to the gun line 114 to suspend the gun line 114.

[0039] In the above-mentioned charging pile, the first end of the traction rope 113 is fixed to the top of the shell 112, and the second end of the traction rope 113 first passes around the movable pulley 108 to suspend and pull the counterweight 109 up and down in the vertical direction; the second end of the traction rope 113 then passes around the fixed pulley 104, which changes the extension direction and force direction of the traction rope 113, making it convenient for the traction rope 113 to be connected to the gun line 114 after it exits the shell 112, so that the user can use the gun line 114 directly by dragging it.

[0040] When using the above-mentioned charging pile, the user pulls the gun line 114, and the gun line 114 stretches the traction rope 113 and gradually extends out of the shell 112. The traction rope 113 is pulled upward by the steering action of the fixed pulley 104 to pull the pulley 108, and the counterweight 109 carried by the movable pulley 108 uses its own weight to balance the tension of the gun line 114 through the traction rope 113; wherein the weight of the counterweight 109 remains unchanged, and the force provided by the counterweight 109 to the gun line 114 through the traction rope 113 remains constant, and will not increase as the gun line 114 is pulled to a longer distance. Since the movable pulley can reduce the pulling force, compared with the solution of suspending the gun line 114 by a balancer in the prior art, it can save the user effort when dragging the gun line 114 to a long distance, which is convenient for the user to use.

[0041] In addition, the charging pile provided in this embodiment uses the gravity of the counterweight 109 to balance the gravity of the gun line 114. The gun line 114 is subjected to constant force when stretched. When use is finished, the gun line 114 can also automatically restore its initial position under the action of the gravity of the counterweight 109, providing a better user experience.

[0042] Furthermore, the pulley assembly in the charging pile provided in this embodiment applies the movable pulley principle, which doubles the movement stroke of the traction rope 113 and greatly increases the use range of the gun line 114.

[0043] The charging station can be configured to further include a tensioning member 106, which is located between the fixed pulley 104 and the cable outlet, and which presses against the traction rope 113. In this embodiment, the charging station is equipped with a tensioning member 106 to keep the traction rope 113 in a taut state, thereby reliably winding around the fixed pulley 104 and preventing the traction rope 113 from detaching from the fixed pulley 104. This is especially true when the gun line is stretched over a long distance, as the traction rope 113 is prevented from derailing from the fixed pulley 104 due to its large angle relative to the housing 112.

[0044] In a specific embodiment, the tensioning member 106 may be configured as a tensioning wheel, and the axis of the tensioning wheel is configured to be parallel to the axis of the fixed pulley 104 .

[0045] In another specific embodiment, referring to FIG5 , the tensioning member 106 includes a bracket 161 fixed to the housing 112. The tensioning member 106 is provided with a threading hole 163 for the traction rope 113 to pass through. A curved barrier 162 may be provided around the threading hole 163. The curved barrier 162 guides the traction rope 113 in its sliding motion, reducing its sliding resistance. It also prevents the traction rope 113 from directly contacting the wall of the threading hole 163, thereby preventing the wall from cutting the traction rope 113.

[0046] The arc-shaped enclosure 162 can be set as an arc plate fixed to the bracket 161. As shown in Figure 5, the arc-shaped enclosure 162 includes four parts, forming a ring (specifically, a rectangle) including a threading hole 163. The part of each part close to the threading hole 163 has a smooth slope, which can prevent the traction rope 113 from being cut when it contacts the hole wall. In addition, the arc-shaped enclosure 162 can also be set as the outer wall of the drum. The drum can be set in multiple numbers, and each drum can be mounted on the bracket 161 so as to rotate around its own axis. All the drums are arranged in sequence along the circumference, and the outer walls of all the drums surround the above-mentioned threading hole 163.

[0047] The upper edge of the threading hole 163 presses against the traction rope 113, and the upper edge of the threading hole is lower than the lower edge of the outlet hole in the shell 112 for leading out the traction rope 113; when the charging pile is in use, the traction rope 113 presses against the upper edge of the threading hole 163 and the lower edge of the outlet hole, ensuring that the traction rope 113 is tensioned under the action of the tensioning member 106.

[0048] Furthermore, the upper edge of the threading hole 163 is also lower than the upper edge of the fixed pulley 104. The traction rope 113 passes around the movable pulley 108 from below and passes around the fixed pulley 104 from above.

[0049] In one embodiment, the tensioning member 106 includes four rollers, wherein the axes of two rollers are arranged in the horizontal direction, and the axes of the other two rollers are arranged in the vertical direction. The rollers with axes arranged in the horizontal direction and the rollers with axes arranged in the vertical direction are arranged alternately to form a rectangular threading hole 163; accordingly, the upper edge of the threading hole 163 is located above and the lower edge of the outer periphery of the roller with the axis arranged in the horizontal direction.

[0050] A guide rail 110 can be mounted within the housing 112, onto which the slider 102 is secured. The counterweight 109 can be secured to the slider 102 using screws or other fasteners. The guide rail 110 must be arranged vertically. In this embodiment, the slider 102 provides a secure mounting base for the counterweight 109. The slider 102 and guide rail 110 work together to guide the counterweight 109 and constrain its path of motion.

[0051] A guide post arranged vertically can also be installed in the housing 112 , and the counterweight 109 is provided with a guide hole for inserting and fitting with the guide post. In the solution provided in this embodiment, the guide post plays a guiding role for the counterweight 109 .

[0052] The counterweight member 109 includes a counterweight cabin 1091 with an opening, a door panel 1092 fixed at the opening of the counterweight cabin 1091 , and a counterweight block 1093 arranged in the counterweight cabin 1091 ; the movable pulley 108 is installed at the upper end of the counterweight cabin 1091 .

[0053] The door panel 1092 can be installed in the opening of the counterweight compartment 1091 through a sheet metal slot provided in the counterweight compartment 1091 for inserting the door panel 1092 and screws for fixing the counterweight compartment 1091 and the door panel 1092. When the door panel 1092 is removed, the counterweight block 1093 can be placed inside the counterweight compartment 1091. The counterweight block 1093 can be made of a material with a high density, such as a cement block, a lead block, or an iron block.

[0054] A first cushion 107 is provided within the housing 112 for contacting the counterweight 109 when the counterweight 109 moves vertically to its upper limit position, and a second cushion 111 is provided for contacting the counterweight 109 when the counterweight 109 moves vertically to its lower limit position. The cushions prevent the counterweight 109 from colliding with the internal structure of the housing 112, thereby improving the safety of the counterweight 109 during vertical movement.

[0055] In a specific embodiment, an upper bracket 101 for limiting the upper limit position of the counterweight 109 and a lower bracket 103 for limiting the lower limit position of the counterweight 109 are installed in the housing 112. The first buffer pad 107 is fixed to the upper bracket 101, and the second buffer pad 111 is fixed to the lower bracket 103. The upper bracket 101 and the lower bracket 103 can each be configured as a sheet metal member.

[0056] Furthermore, the fixed pulley 104 and the tensioning member 106 may be fixed to the upper bracket 101 respectively.

[0057] To facilitate the extraction of the traction rope 113, a reinforcement member 105 may be fixed to the housing 112. The reinforcement member 105 has an outlet hole for extracting the traction rope 113. A smooth metal ring 115 is fixed to the outlet hole. The metal ring 115 may be welded to the reinforcement member 105. The reinforcement member 105 may be a sheet metal member.

[0058] In this embodiment, a metal ring 115 is provided at the wire outlet of the reinforcement member 105. This guides and constrains the traction rope 113 when the gun line 114 is stretched in all directions, preventing the rope from being pulled out or cut. The metal ring 115 is preferably a non-spraying metal ring 115, such as a stainless steel metal ring 115, to ensure good protection while avoiding increased friction on the traction rope 113 caused by spray molding.

[0059] The traction rope 113 can be configured as a steel wire rope or a PE (Polyethylene) rope. This embodiment does not limit the material of the traction rope 113 .

[0060] The charging gun provided in this embodiment has a simple structure, is easy to manufacture, and has low production cost.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0062] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
