Description

Technical Field

[0001] The utility model relates to a charging pile, in particular to a ground track type DC charging pile moving mechanism. Background Art

[0002] In some communities, especially old residential areas and public parking spaces, electric car owners cannot install charging piles with their cars because they do not have fixed parking spaces or independent parking space property rights; due to the shortage of parking spaces, parking spaces with fixed charging piles are often occupied by fuel vehicles, making it impossible for new energy vehicles to charge; the original distribution transformers in the community do not have enough redundant load, making it impossible to build a large number of fixed charging piles. The problem of "difficult charging" has seriously affected the development of new energy vehicles.

[0003] According to the statistics of the application of built private charging piles, the charging piles are used 1-2 times a week, and are idle most of the time, with extremely low efficiency. From the perspective of economic benefits, the construction cost is high and the return on investment period is long. And from the analysis of the use of charging facilities across the country, the low frequency of use of private charging piles has caused a waste of charging facility resources.

[0004] In response to the above problems, the invention patent with application number 202211410757.9 in the prior art proposes a mobile shared orderly door-type charging pile. This charging pile adopts an overhead track. The charging pile is suspended under the track and slides left and right to realize the shared charging function. The main structure of this structural form is above the ground, and the track is long and the structure is large, which has a greater impact on the surrounding environment. Passing people are very likely to collide or damage the charging equipment. In addition, since all cables, charging piles, and tracks are in an overhead form, the overall structural load-bearing and stability requirements are high, so the cost will also increase accordingly. Utility Model Content

[0005] Purpose of the utility model: The purpose of the utility model is to provide a ground track type DC charging pile mobile mechanism. Multiple parking spaces share one charging pile, which can charge new energy vehicles in any parking space in front of the track, effectively solving the problem that new energy vehicles cannot be charged because the parking spaces of fixed charging piles are occupied by oil vehicles. The track of the mechanism is close to the ground, which has lower requirements on the overall load-bearing structure.

[0006] Technical solution: The utility model is a ground track type DC charging pile moving mechanism, including a guide rail fixedly installed on the ground, a mobile charging pile installed on the guide rail and sliding along the guide rail, a control column fixedly installed at one end of the guide rail, a cable trough welded to the rear of the guide rail, and a drag chain and cable placed in the cable trough; one end of the cable is connected to the control column, and the other end thereof is connected to the mobile charging pile through the drag chain. The control column is used to control the sliding of the mobile charging pile. The cable slides along the outer side of the guide rail under the action of the drag chain, thereby keeping synchronous sliding with the mobile charging pile.

[0007] Furthermore, the cable trough adopts a semi-closed cable trough with drainage holes at the bottom. The semi-closed shape of the cable trough can effectively direct rainwater to the outside ground. The bottom of the cable trough has drainage holes, which can reduce the entry of rainwater while promptly draining a small amount of accumulated water inside to prevent the cables from being immersed in water for a long time.

[0008] Furthermore, the guide rail includes two C-shaped steels arranged opposite to each other, which are connected by a plurality of rectangular square tubes, and the plurality of rectangular square tubes are installed at intervals on the bottom surface of the C-shaped steel and fixed to the ground by anchor bolts. This type of track is close to the ground, and has a simple and reliable structure. It can ensure that the track is firmly fixed and prevent water and dust accumulation on the ground and small foreign objects from affecting the sliding of the mobile charging pile in the track. The shape of the C-shaped steel prevents the pulley from sliding out of the track when sliding in the groove, thereby ensuring the safe operation of the equipment.

[0009] Furthermore, the mobile charging pile includes a moving mechanism installed in and matched with the guide rail, a column vertically installed on the upper surface of the moving mechanism, and a charging component installed on the upper end of the column; the mobile charging pile moves left and right along the track as a whole, with little impact on the surrounding environment.

[0010] Furthermore, the mobile mechanism includes a group of driving wheels installed at one end of the mobile mechanism body, and a group of driven wheels installed at the other end and arranged parallel to the group of driving wheels; the driving wheels and the driven wheels slide along the guide rails, and the driving wheels are driven by a DC motor and a matching gear reducer installed inside the column, thereby realizing the overall movement of the mobile charging pile.

[0011] Furthermore, one or more guide bearings are installed between the driving wheel and the driven wheel on the same side of the moving mechanism, and when the mobile charging pile moves along the guide rail, the guide bearing slides closely against the inner wall of the guide rail.

[0012] Furthermore, limit switches are respectively arranged on the outer sides of the driving wheel and the driven wheel to detect the starting point and the end point at both ends of the track.

[0013] Furthermore, obstacle avoidance radars are arranged on both sides of the moving mechanism and the column.

[0014] Furthermore, a cable bracket is provided at the rear side of the mobile mechanism, and the cable bracket is connected to a drag chain inside the cable trough, so that the cable slides along with the mobile charging pile.

[0015] Furthermore, the control column is connected to a distribution box, and the distribution box is used to supply power to the entire mechanism.

[0016] Beneficial effects: Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0017] (1) The track and cable body are close to the ground, and only the charging pile and control column stand above the ground, which has little impact on the surrounding environment and can be better hidden in the green belt. In areas with dense traffic, it can effectively reduce the risk of collision and injury to personnel or damage to equipment caused by collision with other goods.

[0018] (2) The cable is connected to the mobile charging pile through the drag chain in the cable trough, so that the charging gun and charging cable of the mobile charging pile can slide left and right along the track, while also ensuring stable power supply and network communication.

[0019] (3) When the mobile charging pile moves along the track, the guide bearing is close to the inner wall of the C-shaped steel on both sides of the track to ensure that the direction of the moving mechanism will not deviate.

[0020] (4) The limit switch is used to detect the starting and ending points of the track. When the vehicle moves to the starting or ending point of the track, the limit switch sends a stop signal to the motor. This way, even if the owner fails to release the start button in time during operation, the mobile charging station will not slide off the track.

[0021] (5) The utility model develops a mobile charging device to meet the charging needs of public parking spaces where private charging piles cannot be installed. The device is installed in public parking spaces with charging needs and can provide charging services for multiple parking spaces. Multiple parking spaces share one charging pile. As long as there is a vacant parking space, electric vehicles can park and charge. This device not only meets the charging needs of electric vehicle owners who are unable to install private charging piles, but also solves the problem of mixed parking of oil and electric vehicles in fixed charging pile spaces, which affects the charging of electric vehicles, as well as the low efficiency of fixed private charging piles.

[0025] The technical solution of the utility model is described in detail below in conjunction with specific implementation methods and accompanying drawings.

[0026] like Figure 1As shown, the ground track type DC charging pile mobile mechanism of the utility model includes two parts: a mobile charging pile 1 and a guide rail 3, wherein the guide rail 3 is fixedly installed on the ground, specifically installed behind the parking space 7, and the mobile charging pile 1 is installed on the guide rail 3 and can slide back and forth along the guide rail 3. A cable trough 4 is welded behind the guide rail 3, and a drag chain 9 and a cable are placed in the cable trough 4. One end of the cable is connected to the control column 5, and the other end is connected to the mobile charging pile 1 through the drag chain 9, so that the charging gun and charging cable of the mobile charging pile can slide left and right along the track, while ensuring stable power supply and network communication. A control column 5 is fixedly installed at one end of the guide rail 3, and the control column 5 is used to control the sliding of the mobile charging pile 1. The cable slides along the outer side of the guide rail 3 under the action of the drag chain 9, thereby keeping synchronous sliding with the mobile charging pile 1. The control column 5 is connected to the distribution box 6, and the distribution box 6 is used to power the entire mechanism. The mobile charging pile 1 completes the access to the charging power supply and the network through the distribution box 6. The control column 5 is provided with an emergency stop button and a button for controlling the mobile charging pile to slide left and right. During operation, if the owner encounters an emergency, he can directly press the emergency stop button to stop the mobile charging pile from moving further to avoid accidents.

[0027] like Figure 2 As shown, in this embodiment, the cable trough 4 adopts a semi-closed cable trough, and a drainage hole is opened at the bottom of the cable trough 4, which can effectively guide rainwater to the outside ground. The drainage holes are opened on the bottom of the cable trough. While reducing the entry of rainwater, a small amount of accumulated water inside is discharged in time to avoid the cables being immersed in water for a long time.

[0028] In this embodiment, the guide rail 3 is welded from steel sections, including two C-section steels arranged opposite to each other, which are connected by a number of rectangular square tubes, which are installed at intervals on the bottom surface of the C-section steel and fixed to the ground by anchor bolts. The rectangular square tubes are also used to raise the guide rail 3. This form makes the track close to the ground, ensures that the track is firmly fixed, the load-bearing structure is simple and reliable, and prevents water and dust on the ground or small foreign objects from entering the track to affect the sliding of the mobile charging pile. The shape of the C-section steel prevents the pulley from sliding out of the track when sliding in the groove, thereby ensuring the safe operation of the equipment.

[0029] like Figure 3As shown, the mobile charging pile 1 includes a charging component 11, a column 12, and a moving mechanism 13. The moving mechanism 13 is at the bottom of the entire mobile charging pile, and the column 12 and the charging component 11 are fixed on the moving mechanism 13. The mobile charging pile as a whole moves left and right along the guide rail 3. Specifically, the moving mechanism 13 is installed in the guide rail 3 and cooperates with the guide rail 3. The column 12 is vertically installed on the upper surface of the mobile mechanism 13, and the charging component 11 is installed on the upper end of the column 12. The mobile mechanism 13 includes a group of driving wheels 133 installed at one end of the mobile mechanism body, and a group of driven wheels 135 installed at the other end thereof and arranged parallel to the group of driving wheels 133; the driving wheel 133 and the driven wheel 135 slide along the guide rail 3, and the driving wheel 133 is driven by a DC motor and a matching gear reducer installed inside the column 12. A cable holder is arranged at the rear side of the mobile mechanism 13, and the cable holder is connected to the drag chain 9 inside the cable trough 4, so that the cable can slide with the mobile charging pile 1, so that the cable can slide with the mobile charging pile, and provide a stable and continuous power supply and communication for the mobile charging pile. All power supply and communication cables of the mobile charging pile 1 are connected to the charging assembly 11 above through the column 12. The motor, radar and other control, detection and communication systems of the mobile mechanism 13 are also installed in the column. An inspection cover is arranged behind the column to facilitate wiring or troubleshooting of the mobile charging pile during installation or troubleshooting. The charging assembly 11 has a built-in charging master control module, a charging module, an electric meter and a card swiping module, etc., and the entire system can realize remote charging control and settlement. The screen above can display the degree of charging, so that the owner can accurately assess the remaining charging time.

[0030] In this embodiment, two guide bearings 134 are installed between the driving wheel 133 and the driven wheel 135 on the same side of the mobile mechanism 13. When the mobile charging pile 1 moves along the guide rail 3, the guide bearing 134 slides close to the inner wall of the C-shaped steel on both sides of the guide rail 3 to ensure that the direction of the mobile mechanism 13 will not be offset. Due to the shape of the C-shaped steel, the driving wheel 133 and the driven wheel 135 will be stuck in the groove of the C-shaped steel and will not fall out.

[0031] In this embodiment, a limit switch 132 is provided on the outer side of the driving wheel 133 and the driven wheel 135. The function of the limit switch 132 is to detect the starting point and the end point of the two ends of the track. When the whole moves to the starting point or the end point of the track, the limit switch will send a stop signal to the motor to prevent the mobile charging pile from sliding out. In this way, even if the owner fails to release the start button in time during the operation, the mobile charging pile will not slide out of the track and damage the equipment.

[0032] In this embodiment, obstacle avoidance radars 131 are set on both sides of the mobile mechanism 13 and the column 12. The function of the obstacle avoidance radars 131 on both sides of the mobile mechanism 13 is to detect whether there are foreign objects inside the guide rail 3 or in front of the movement, so as to prevent foreign objects from entering the track and hindering the movement of the mobile charging pile. A set of obstacle avoidance radars 131 is also set on the left and right sides of the column 12. In order to detect foreign objects inside the track, the two sets of obstacle avoidance radars set by the mobile mechanism are installed at a low position, which is easily blocked by the edge of the track, and there is a blind spot above the detection track. Adding two sets of obstacle avoidance radars on the column 12 can well make up for the blind spot of the obstacle avoidance radar set on the mobile mechanism, and timely detect whether there are branches or human limbs that mistakenly enter the movement range of the mobile charging pile, so as to avoid damage to the equipment or personal collision injury accidents. However, the radar installed on the column is also unable to detect foreign objects inside the C-type track due to the obstruction of the edge of the track. Therefore, these four sets of obstacle avoidance radars are indispensable for safe operation.

[0033] When the owner needs to charge the new energy vehicle, he should first park the new energy vehicle in any parking space in front of the track. After the vehicle is parked, the owner needs to walk to the control column, press the start button in the corresponding direction according to the parking position, move the mobile charging pile to the rear of his own vehicle, and then remove the DC charging gun from the mobile charging pile and insert it into the charging port of the new energy vehicle. After the charging gun is plugged in, the owner uses the mobile phone to scan the code to start the charging pile through the network to lock the charging gun and charge the new energy vehicle. Since the charging pile is a DC charging pile, the charging speed is fast. After the owner waits near his own car for charging to be completed, he will settle the bill through mobile payment.

[0034] When the owner completes the settlement, the charging gun is automatically unlocked. The owner pulls out the charging gun and plugs it back into the mobile charging pile. During periods when parking spaces are tight, the car needs to be driven out of the parking space as soon as possible. During periods when parking spaces are not tight, the car can be temporarily left unmoved. The owner of the new energy vehicle will then park the car in other parking spaces around and operate the mobile charging pile for charging. This technical solution effectively solves the problem that new energy vehicles cannot be charged because the parking spaces of fixed charging piles are occupied by oil vehicles, and the problem of low efficiency of fixed private charging piles. In addition, the track of this mechanism is close to the ground and can be easily hidden in the green belt behind the parking space, which has little impact on the environment and reduces the risk of collisions between people in crowded areas.

[0035] This solution aims to meet the charging needs of public parking spaces where private charging piles cannot be built. A mobile charging device is developed and built in public parking spaces with charging needs. It can provide charging services for multiple parking spaces. Multiple parking spaces share one charging pile. As long as there is an empty parking space, electric vehicles can park and charge. The technology of this utility model not only meets the charging needs of electric vehicle owners who cannot install private charging piles, but also solves the problem of mixed parking of oil and electricity in fixed charging pile parking spaces, which affects the charging of electric vehicles and the low efficiency of fixed private charging piles.

[0036] In the technical solution of the utility model, the track is installed on the ground, and the mobile charging pile equipped with a charging gun and a charging cable can slide left and right along the track, and can charge new energy vehicles in any parking space in front of the track, effectively solving the problem that the parking space of the fixed charging pile is occupied by a gasoline truck and the new energy vehicle cannot be charged, and the problem of low efficiency of fixed private charging piles. The track of this mechanism is close to the ground, and the overall load-bearing structure requirements are lower. It can be hidden in the green belt behind the parking space, has little impact on the environment, and avoids the risk of collision in crowded areas.
