Description

Technical Field

[0001] This application relates to the technical field of charger equipment, and particularly to a dual-gun charger with a gun line management system. Background Art

[0002] A charger, also known as a charging pile, refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Generally, the charging pile provides two charging methods: conventional charging and fast charging.

[0003] Currently, when an electric vehicle is charging using a charger, the charging gun line of the charging gun head often drags on the ground and is damaged by friction, and the charging gun lines may also be randomly crossed and entangled. These situations may cause the outer skin of the charging gun line to be damaged, reducing the service life of the charging gun line and posing safety hazards, resulting in an increase in operation and maintenance costs. Therefore, further improvements can be made. Utility Model Content

[0004] In order to improve the service life of the charging gun line and reduce the increase in operation and maintenance costs caused by friction damage, this application provides a dual-gun charger with a gun line management system.

[0005] A dual-gun charger with a gun line management system provided by this application adopts the following technical solution: A dual-gun charger with a gun line management system includes a housing, a circuit assembly disposed inside the housing, a charging gun line electrically connected to the circuit assembly, and a charging gun head connected to the charging gun line. First wire grooves for the charging gun line to pass through and mounting seats for fixing the charging gun head are provided on the opposite side walls of the housing.

[0006] A gun line management mechanism is further disposed inside the housing. The gun line management mechanism is disposed at the top inside the housing. The gun line management mechanism includes a balancer body and a control rope wound inside the balancer body. Second wire grooves for the control rope to pass through, steering pulleys for the control rope to move, and gun line clips connected to the charging gun line are also provided on the opposite side walls of the housing. One end of the control rope is wound around the balancer body, and the other end of the control rope is wound around the steering pulley and connected to one end of the gun line clip. The charging gun line is inserted into and fixed in the gun line clip.

[0007] By adopting the above technical solution, a gun line management mechanism is set up, and the balancer body and the steering pulley are used in cooperation. The balancer body controls the contraction of the control rope, and the steering pulley steers the control rope, so that the gun line clamp connected to one end of the control rope is automatically released and recovered in the air along with the control rope, and then the charging gun line connected to the gun line clamp also moves in the air along with the control rope, avoiding dragging on the ground and contact friction during the process, thereby extending the service life of the charging gun line and reducing operation and maintenance costs.

[0008] Optionally, a steering protective shell is provided on the side wall of the outer shell at the position of the second wire threading groove, the steering pulley is arranged in the steering protective shell, and a third wire threading groove for the control rope to be threaded is provided on the steering protective shell. The control rope enters the steering protective shell from the second wire threading groove and passes through the third wire threading groove arranged by the steering pulley to be connected with the gun wire clamp.

[0009] By adopting the above technical solution, a steering protection shell is set up, and the steering pulley and control rope inside the steering protection shell are protected, thereby reducing the wear of the steering pulley and the control rope directly caused by severe outdoor weather, thereby increasing the service life of the steering wheel.

The control rope is connected to the gun line clamp after passing through the third threading groove and the four-way pulley.

[0011] By adopting the above technical solution, a four-way pulley is set, and a steering pulley is used to cooperate with the four-way pulley. The steering pulley is used to move and steer the control rope, so that horizontal movement is converted into up and down movement. The four-way pulley is used to increase the moving direction of the control rope, so that when the user pulls the charging gun head, the control rope connected to the gun wire clamp is driven to move and pull in any direction.

[0012] Optionally, the four-way pulley comprises a pulley seat connected by a first cylindrical pin, a wire outlet is provided in the middle of the pulley seat, and needle bearing wheels are respectively provided on the peripheral sides of the wire outlet of the pulley seat;

[0013] Connecting blocks are respectively arranged on both sides of the pulley seat, and the connecting blocks are fixedly connected to the steering protection shell through a first fixing member.

[0014] By adopting the above technical solution, when the control rope moves from the steering pulley to the four-way pulley, the control rope continues to move through the outlet of the pulley seat. When the control rope needs to be turned, the control rope will contact the needle bearing wheel arranged on the peripheral side of the outlet, and the needle bearing wheel will assist in steering the control rope, thereby reducing the friction damage caused by the steering pulley that can only move the steering line in a single direction in the absence of a four-way pulley.

[0015] Optionally, a balancer mounting bracket is provided at the top inside the housing body. The balancer body is disposed within the balancer mounting bracket. The number of the balancer bodies is two, and the two balancer bodies are correspondingly connected to the charging gun heads on the housing body.

[0016] By adopting the above technical solution, two balancer bodies are provided, and the two balancer bodies cooperate with the charging gun heads on both sides of the housing body respectively, so that the charging gun wires on both sides are protected by the gun wire management mechanism.

[0017] Optionally, the steering pulley includes a pulley bracket. A roller nylon wheel is disposed within the pulley bracket. The roller nylon wheel is connected to the pulley bracket by a second cylindrical pin, and the control rope moves through the roller nylon wheel.

[0018] Connecting holes are respectively formed on both sides of the bottom of the pulley bracket, and the connecting holes are fixedly connected to the steering protection shell through second fixing members.

[0019] By adopting the above technical solution, when the control rope enters the steering pulley and makes a steering movement, the control rope passes through the roller nylon wheel on the pulley bracket, and the moving direction of the control rope is changed through the rotation of the roller nylon wheel, thereby realizing the change of the moving direction of the control rope.

[0020] Optionally, an opening and closing door is provided on the side wall of the housing body, and an operating platform is provided on the opening and closing door.

[0021] By adopting the above technical solution, the opening and closing door is provided, and the operating platform is provided on the opening and closing door.

The operating platform can enable users to operate more conveniently during the charging process, such as swiping cards, touch screen operations, etc., enhancing the user's operation experience.

[0022] Optionally, inspection side doors are respectively formed on the opposite side walls of the housing body.

[0023] By adopting the above technical solution, the inspection side doors are provided. The inspection side doors can allow maintenance personnel to conveniently access the circuit assembly inside the housing body, facilitating regular inspections, maintenance, and necessary repair work.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

By cooperating with the balancer body and the steering pulley, the balancer body controls the contraction of the control rope, and the steering pulley plays a role in steering the control rope, enabling the gun line clip connected to one end of the control rope to be automatically released and retrieved in the air. Consequently, the charging gun line connected to the gun line clip also moves in the air along with the control rope, avoiding dragging on the ground and contact friction during the process, thereby prolonging the service life of the charging gun line and reducing the operation and maintenance costs.

One end of the charging gun line 5 is electrically connected to the circuit assembly 3 inside the outer housing 100, and the other end of the charging gun line 5 passes through the first wire groove and penetrates the outer housing 100 to be connected to the charging gun head 4. The charging gun head 4 is fixedly placed in the mounting seat 6;

[0041] An openable opening and closing door 7 is arranged on the front side of the outer housing 100. An operating platform 71 is arranged at a position slightly above the middle of the opening and closing door 7. Maintenance side doors 8 are also respectively arranged on two opposite side walls of the outer housing 100. The maintenance side doors 8 are located below the mounting seat 6.

[0042] In the actual use process, the opening and closing door 7 and the maintenance side door 8 are provided. On the one hand, the opening and closing door 7 is provided with an operating platform 71 on the opening and closing door 7. The opening and closing door 7 can prevent non-professionals from contacting the circuit assembly 3, improving the safety of the charging process. The operating platform 71 can enable users to operate more conveniently during the charging process, such as swiping cards, touch screen operations, etc., improving the user's operation experience. On the other hand, the maintenance side door 8 can allow maintenance personnel to conveniently access the circuit assembly 3 inside the outer housing 100, facilitating regular inspections, maintenance, and necessary repair work.

[0043] Refer to Figure 1 , 3, 4. Specifically, in this embodiment, in order to reduce the problem of friction between the charging gun cable 5 and the ground during the charging of the tram, a cable management mechanism 1 is provided at the top inside the outer housing 100. The cable management mechanism 1 includes a balancer mounting bracket 11. Both sides of the balancer mounting bracket 11 are fixedly arranged on the inner top surface of the outer housing 100 by bolts. There are two independent balancer bodies 14 inside the balancer body 14, and each balancer body 14 corresponds to one side of the charging gun cable 5 respectively, so that the charging gun cables 5 on both sides are protected by the cable management mechanism 1. A balancer winch 12 is arranged inside the balancer body 14, and a control rope 13 for connecting with the charging gun cable 5 is wound inside the balancer winch 12. In this embodiment, the balancer body 14 adopts a spring balancer in the prior art as the body, and no more explanations are given here;

[0044] Second wire grooves and a steering protection shell 2 are respectively arranged on the opposite side walls of the outer housing 100. The steering protection shell 2 is located at the position of the second wire groove of the outer housing 100. A third wire groove is arranged at the bottom of the steering protection shell 2, so that the control rope 13 located inside the balancer body 14 can extend out of the outer housing 100 through the second wire groove in sequence and extend out of the steering protection shell 2 through the third wire groove;

[0045] A steering pulley 21 and a four-way pulley 22 are respectively arranged on the steering protection shell 2. Specifically, the steering pulley 21 is arranged at the inner top of the steering protection shell 2, and the steering pulley 21 is on the same horizontal line as the balancer body 14; the four-way pulley 22 is arranged at the bottom of the steering protection shell 2 and is located at the position of the third wire groove. A gun cable clip 9 is arranged at the bottom of the four-way pulley 22. Finally, the control rope 13 located inside the balancer body 14 enters the steering protection shell 2 through the second wire groove, and the horizontal movement is changed to vertical movement through the steering pulley 21, and then passes through the third wire groove to extend out of the steering protection shell 2 and enters the four-way pulley 22 for continuous movement in any direction. The moved control rope 13 is finally fixedly connected to one end of the gun cable clip 9, and the charging gun cable 5 is inserted and fixedly arranged in the gun cable clip 9.

[0046] During actual use, the gun line management mechanism 1 is set up. With the cooperation of the balancer body 14, the steering pulley 21, and the four-way pulley 22, the balancer body 14 is used to control the contraction of the control rope 13. The steering pulley 21 plays a role in steering the control rope 13, enabling the gun line clip 9 connected to one end of the control rope 13 to be automatically released and retrieved in the air along with the control rope 13, converting horizontal movement into vertical movement. The four-way pulley 22 is used to increase the selection of the movement direction of the control rope 13, so that when the user pulls the charging gun head 4, the control rope 13 connected to the gun line clip 9 is driven to move in any direction. Consequently, the charging gun line 5 connected to the gun line clip 9 also moves in the air along with the control rope 13, avoiding dragging on the ground and contact friction during the process, thereby extending the service life of the charging gun line 5 and reducing the operation and maintenance costs.

[0047] Reference Figure 4 、 5 Specifically, in this embodiment, the steering pulley 21 includes a U-shaped pulley bracket 211. A roller nylon wheel 212 is rotatably arranged inside the pulley bracket 211. Second installation sockets are respectively provided in the middle of the roller nylon wheel 212 and the middle of the pulley bracket 211. The roller nylon wheel 212 and the pulley bracket 211 are fixedly connected by inserting a second cylindrical pin 213 into the installation sockets. The control rope 13 changes its moving direction by winding around the roller nylon wheel 212. Both sides of the bottom of the pulley bracket 211 extend horizontally outwards to form installation parts 214, and connection holes are provided in the installation parts 214. The top inside the steering protection shell 2 is connected to the installation parts 214 through a second fixing member 215 passing through the connection holes, thereby realizing the installation of the steering pulley 21 on the top inside the steering protection shell 2. In this embodiment, the second fixing member 215 uses a bolt as the fixing connecting piece.

[0048] During actual use, when the control rope 13 enters the steering pulley for steering movement, the control rope 13 passes through the roller nylon wheel 212 on the pulley bracket 211, and its moving direction is changed through the rotation of the roller nylon wheel 212, thereby realizing the change of the moving direction of the control rope 13.

[0049] Reference Figure 4 、 6Specifically, in the present embodiment, the four-way pulley 22 comprises a rectangular pulley seat 221, the pulley seat 221 is fixed by a first cylindrical pin 222, a through wire outlet 223 is provided in the middle of the pulley seat 221, and needle bearing wheels 224 are rotatably provided on the peripheral sides of the wire outlet 223 of the pulley seat 221, and connecting blocks 225 are provided on both sides of the pulley seat 221, and mounting holes are provided on the connecting blocks 225. The bottom of the steering protection shell 2 is connected to the connecting block 225 through the mounting hole provided by the first fixing member 226, so as to realize the installation of the four-way pulley 22 at the bottom of the steering protection shell 2. In the present embodiment, the first fixing member 226 adopts bolts as the fixing connecting member.

[0050] During actual use, when the control rope 13 moves from the steering pulley 21 to the four-way pulley 22, the control rope 13 continues to move through the outlet 223 of the pulley seat 221. When the control rope 13 needs to be turned, the control rope 13 will contact the needle bearing wheel 224 arranged on the periphery of the outlet 223, and the needle bearing wheel 224 will assist in steering the control rope 13, thereby reducing the friction damage caused by the steering pulley 21 that can only move the steering line in a single direction when there is no four-way pulley 22.

[0051] The implementation principle of a dual-gun charger with a gun line management system in the embodiment of the present application is as follows: a gun line management mechanism 1 is set up, and the balancer body 14, the steering pulley 21 and the four-way pulley 22 are used to cooperate. The balancer body 14 is used to control the contraction of the control rope 13, and the steering pulley 21 plays a steering role on the control rope 13, so that the gun line clamp 9 connected to one end of the control rope 13 is automatically released and recovered in the air along with the control rope 13, so that the horizontal movement becomes an up and down movement, and the four-way pulley 22 is used to increase the choice of the moving direction of the control rope 13, so that when the user pulls the charging gun head 4, the control rope 13 connected to the gun line clamp 9 is driven to move and pull in any direction. In addition, the charging gun line 5 connected to the gun line clamp 9 also moves in the air following the control rope 13.
