Description

Technical Field

[0001] The present invention belongs to the technical field of charging, and in particular relates to a vehicle charging method and a mobile shared umbrella-shaped charging pile. Background Art

[0002] The existing charging piles occupy a large amount of ground space and are expensive, which leads to many obstacles when installing existing charging piles in parking lots with relatively dense populations such as residential communities and workplaces. When traditional charging piles are built in old communities, they often encounter a series of problems in the face of the complex situation of old communities, such as insufficient parking spaces: the parking space layout in old communities may be relatively compact and space is limited, and it may be difficult to find a suitable location to install charging piles. Occupying public space: In some cases, installing charging piles may occupy public areas or driveways, which may cause residents to oppose or require the replanning of parking space layout. Power load issues: The power facilities in old communities may not be able to carry the additional charging demand. The power capacity and line design of the old distribution network may not be sufficient to support the high power requirements of charging piles, and power system transformation may be required. Aging of cables and distribution equipment: The cables and distribution equipment in old communities may be aged and do not meet the current technical requirements and safety standards of charging piles. Construction and transformation costs: The cost of infrastructure transformation (such as power system upgrades) and charging pile construction is high, which may exceed the budget constraints of old communities. Operation and maintenance costs: The daily operation and maintenance of charging piles requires additional resources, which may cause economic pressure on community management or property companies. Safety issues: The installation of charging piles needs to consider safety, such as preventing overheating, electrical short circuits and other problems, and requires comprehensive safety inspections and maintenance. Maintenance management: The troubleshooting and repair of charging piles require professional technical support, and it may be necessary to establish a corresponding maintenance mechanism and service system. In view of these problems and combined with the characteristics of old communities, it is urgent to design a new charging pile.

[0003] At the same time, most existing vehicles still need manual operation when charging. Generally, users need to remove the charging gun from the charging pile, drag the heavy cable, plug it into the charging port of the vehicle, and then turn on the charging switch. The entire operation process is relatively cumbersome and the degree of automation is low, which brings great inconvenience to users and makes the user's charging experience poor. There are also problems such as random parking of vehicles in old communities, resulting in some vehicles being parked far away from the charging pile, the charging cable is not long enough, and they cannot be charged in time.

[0064] Compared with the prior art, the embodiments of the present invention have at least the following advantages:

[0065] 1. In view of the irregular parking areas and chaotic and dense parking of vehicles in old communities, a mobile shared umbrella-shaped charging pile is designed to be more suitable for charging in old communities. The mechanical structure of the rotatable charging pile main pole and the liftable charging pole is used, so that the charging gun can be freely adjusted to the appropriate position for charging. A cable clip is provided in the charging pile main pole to prevent the cable from moving or loosening during use, thereby reducing potential safety hazards and cable wear, extending the service life of the cable, and helping to arrange the cables neatly together to avoid cable entanglement, crossing or disorder, and facilitating maintenance and inspection. The guardrail has a position for solar panels. By utilizing solar energy, the charging pile can generate part or all of the required electricity, thereby reducing dependence on traditional grid electricity. A protective cover is added to the lifting gas pressure rod to prevent dust, dirt, liquid, etc. from entering the gas pressure rod, thereby extending its service life and maintaining its stable performance. The charging gun has three specifications: DC 20KW, DC 40KW and DC 60KW to meet the different needs of users. This charging pile can charge new energy vehicles in any parking space. Installing one charging pile can serve multiple parking spaces, fundamentally solving the problem of charging difficulties in old communities.

[0066] 2. Combined with the camera, the improved YOLOV8 recognition algorithm is used to identify the charging port of the vehicle. The main improvements are: (1) The backbone of the original YOLOV8 network is replaced with the MobileNet V4 network. MobileNet V4 proposes a universal inverted bottleneck (UIB) block, which is an adjustable module suitable for efficient network design. It is flexible and can adapt to various optimization objectives without increasing the search complexity. Temporary trade-offs can be made between spatial and channel mixing to expand the perception field of view as needed and maximize computational utilization. (2) The attention mechanism Swin Transformer is added to enhance the target detection of small objects. The shift of the window partitions between consecutive self-attention layers allows the improved network to learn cross-window information, so that the improved network can process super-resolution images, save computational effort, and pay attention to global and local information.

[0067] 3. Compared with traditional charging piles, mobile shared umbrella charging piles can monitor the power load of the area in real time. At the same time, mobile shared umbrella charging piles have 20KW, 40KW and 60KW charging powers. Combined with fuzzy reasoning algorithms, they recommend users to use different charging powers, which can effectively adjust the charging power. Sensors are used to collect parameters such as current, voltage and temperature of the transformer load in the area, and then the peak, valley and normal periods are judged through fuzzy reasoning algorithms. Users are recommended to choose different charging powers based on the judged peak, valley and normal periods. This can reduce the peak-valley difference in electricity consumption and adjust the transformer load rate. Users can also enjoy relevant preferential policies for charging during low-peak periods, thereby achieving orderly electricity consumption, helping to reduce peaks and fill valleys, and facilitating safe and stable operation of the power grid.

[0068] 4. It is highly adaptable and can use the software and hardware control system to realize the automatic adjustment of the charging gun position and the automatic retraction of the charging gun cable. After regional construction, it can also plan the optimal route for vehicles that need to be charged based on the charging situation, which can greatly shorten the user's charging time and greatly improve the convenience.

[0069] 5. In view of the irregular parking areas in old communities and the different postures of the vehicle body relative to the charging pile caused by parking chaos, two charging strategies with different working conditions are designed to solve this problem. When the user is ready to charge, the camera of the charging pile will detect whether the vehicle is in front of or behind the pile body, and then select two working conditions. When it is in the front, it is working condition one, and the rotation angle of the main pole of the charging pile is controlled at 0°-160°. If the vehicle is parked behind the charging pile, working condition two is used. At this time, the rotation angle of the main pole of the charging pile is 0°-200°. Then the improved YOLOV8 network is used to identify the charging port. After determining the position of the charging port, the main pole of the charging pile is rotated to a certain angle and parked in a suitable position. At this time, the user can take out the gun to charge.

[0086] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0087] There may not be regular parking areas in old residential areas, which will inevitably lead to random parking and different vehicle postures. To address this problem, this design has two different working conditions to solve it.

[0088] Figure 1 FIG. 2 shows a flow chart of a vehicle charging method according to an embodiment of the present invention. Figure 1 As shown, a vehicle charging method proposed by the present invention comprises:

[0089] Step S101: start;

[0090] Step S102: When the user parks the vehicle and prepares to charge, the camera 14 of the charging pile detects the parking position of the vehicle;

[0091] Step S103: Determine whether the vehicle is in front of or behind the charging pile;

[0092] Step S104: when the vehicle is in front of the charging pile, it is working condition 1, and the rotation angle of the charging pile main pole 1 is 0-160°;

[0093] Step S105: When the vehicle is behind the charging pile, it is working condition 2, and the rotation angle of the charging pile main pole 1 is 0-200°;

[0094] Step S106: using an improved deep learning model YOLOV8 network (You Only Look Once version 8, a fast and accurate target detection algorithm) to identify the charging port of the vehicle;

[0095] Step S107: Determine whether the charging port position is identified;

[0096] Step S108: If the charging port position is identified, jump to step S114;

[0097] Step S109: If the charging port position is not identified;

[0098] Step S110: determining whether the license plate and the ventilation grille are recognized, and determining whether the front or rear of the vehicle is facing the charging pile;

[0099] Step S111: When the license plate and ventilation grille are recognized, the front of the vehicle faces the charging pile. Since the charging port of most new energy vehicles on the market is located on the left side of the rear of the vehicle, the main pole 1 of the charging pile is rotated rightward, and the process jumps to step S114;

[0100] Step S112: When the license plate is recognized but the ventilation grille is not recognized, the rear of the vehicle faces the charging pile, the main pole 1 of the charging pile is rotated to the left, and the process jumps to step S114;

[0101] Step S113: When the license plate and ventilation grille are not recognized, it means that the vehicle is parked with the side without the charging port facing the charging pile, so the charging pile main pole 1 is rotated to the other side of the vehicle body, and the process goes to step S114;

[0102] Step S114: Rotate the charging pile main pole 1 so that the charging gun 15 faces the charging port;

[0103] Step S115: The user takes out the charging gun 15 to charge the vehicle;

[0104] Step S116: End.

[0105] In the recognition of the charging port of camera 14, the improved YOLOV8 network structure is used, the backbone of the original network is replaced with the MobileNet V4 network, and the attention mechanism Swin Transformer (Hierarchical Vision Transformer using Shifted Windows) is added to enhance the target detection of small objects. The Universal Inverted Bottleneck (UIB) block is proposed in MobileNet V4, which is an adjustable module suitable for efficient network design. It is flexible and can adapt to various optimization goals without increasing the search complexity. Two optional DWs are introduced in the universal inverted bottleneck block. The DW module is a depth-separable convolution module. The main structure is the depth convolution module: convolution operation is performed on each channel of the input feature map, and the convolution kernel size used is usually 3x3. Each convolution kernel only focuses on the features of one input channel. Point-by-point convolution module: the feature map after the depth convolution is integrated through 1x1 convolution, and the number of channels is adjusted for information fusion and feature conversion. One of the two DW modules is located before the expansion layer, and the other is located between the expansion and projection layers. At each network stage, UIB provides the flexibility to (1) temporarily trade off between spatial and channel mixing, (2) expand the receptive field of view as needed, and (3) maximize computational utilization. A key design element of the Swin Transformer is its shift of window partitions between consecutive self-attention layers, which allows the improved network to learn cross-window information, enabling the improved network to process super-resolution images, save computation, and pay attention to global and local information.

[0106] like Figure 2 As shown, in some embodiments, the improved deep learning model YOLOV8 network includes a backbone network Backbone, a neck network Neck, and a head network Head;

[0107] The backbone network, the neck network and the head network are connected in sequence.

[0108] The backbone network is the basis of the improved network and is responsible for extracting features from the input image. These features are the basis for subsequent network layers to perform object detection. The neck network is located between the backbone network and the head network, and its function is to perform feature fusion and enhancement. The head network is the decision-making part of the object detection model and is responsible for generating the final detection results.

[0109] In some embodiments, the backbone network includes a first separable convolutional layer, an inverted bottleneck layer, a Swin Transformer layer, several universal inverted bottleneck layers, and a second separable convolutional layer connected in sequence.

[0110] In some embodiments, the inverted bottleneck layer includes a point-by-point convolution layer, a depth-wise separable convolution layer, and a point-by-point convolution layer connected sequentially.

[0111] In some embodiments, the plurality of universal inverted bottleneck layers include a first universal inverted bottleneck layer, a second universal inverted bottleneck layer, and a third universal inverted bottleneck layer.

[0112] In some embodiments, the neck network includes a first layer, a second layer, and a third layer;

[0113] The first layer includes a first upsampling module, a first connection module, a first feature extraction module and a first convolution module;

[0114] The first universal inverted bottleneck layer is connected to the first upsampling module and the first connection module respectively;

[0115] The first connection module is connected to the first feature extraction module and the first convolution module respectively.

[0116] In some embodiments, the second layer includes a second connection module, a second feature extraction module, a second upsampling module, a third connection module, a third feature extraction module, and a second convolution module;

[0117] The second connection module is respectively connected to the third universal inverted bottleneck layer, the first upsampling module and the second feature extraction module;

[0118] The second feature extraction module is connected to the third connection module and the second upsampling module respectively;

[0119] The third connection module is connected to the third feature extraction module and the second convolution module respectively;

[0120] The third feature extraction module is connected to the first convolution module.

[0121] In some embodiments, the third layer includes a fourth connection module and a fourth feature extraction module;

[0122] The fourth connection module is respectively connected to the second separable convolutional layer, the second upsampling module and the fourth feature extraction module;

[0123] The fourth feature extraction module is connected to the second convolution module.

[0124] In some embodiments, the head network includes a first detection module, a second detection module, and a third detection module arranged in parallel;

[0125] The first detection module is connected to the first feature extraction module;

[0126] The second detection module is connected to the third feature extraction module;

[0127] The third detection module is connected to the fourth feature extraction module.

[0128] First, the image is input to the first separable convolution layer Convbn to extract features, and then transmitted to the inverted bottleneck layer fuseb_ib. The structure of the inverted bottleneck layer generally includes a point-by-point convolution (1x1 convolution) to expand the number of channels of the feature map, followed by a depthwise separable convolution, and then another point-by-point convolution to compress the number of channels. This structure first increases the dimension of the feature map through point-by-point convolution, so that the depthwise separable convolution can operate in a higher-dimensional space, thereby capturing richer features. Afterwards, the dimension is compressed back through point-by-point convolution to reduce the amount of calculation and the number of parameters.

[0129] Then, Swin Transformer is added between the inverted bottleneck layer fuseb_ib and the universal inverted bottleneck (UIB) layer. By dividing the image into fixed-size windows for self-attention calculation, Swin Transformer effectively captures local features. The window translation mechanism (shifted window) enables the network to capture global information across windows, improving the continuity of information transmission. The information is then transmitted to three universal inverted bottleneck (UIB) layers to expand the image's perception field of view and increase computational efficiency. Finally, the information is transmitted to the second separable convolution Convbn layer for feature extraction.

[0130] In the neck network (Neck), C represents the connection module (Concat), which can splice different feature maps of the upper and lower layers. Upsample means that upsampling usually splices or fuses the upsampled feature map with feature maps from other layers (such as deeper layers). This fusion helps to combine high-level semantic information and low-level detail information, thereby improving the accuracy and performance of target detection. As a feature extraction module, the C2f module consists of Conv convolution blocks, Split (separation blocks), n Bottleneck bottleneck blocks, and Concat. Split refers to the operation of dividing the feature map into multiple parts. The Bottleneck block is a commonly used module designed to reduce image complexity and the number of parameters while retaining the performance of the model. Among them, Concat receives the output of Split and n Bottleneck, splices them together, and uses Conv for feature fusion. The convolution module (Conv) outputs the image features of different stages in the backbone network to the neck network, and outputs the image features in the first universal inverted bottleneck (UIB) layer, the third universal inverted bottleneck (UIB) layer, and the second separable convolution Convbn layer respectively. When the image features are output in the first universal inverted bottleneck (UIB) layer, the first connection module is connected to the first feature extraction module (C2f), and after feature extraction, it is output to the head network to form the first feature map, and then output to the first detection module (Detect) for object detection.

[0131] The image features output by the third universal inverted bottleneck (UIB) layer are output to the second feature extraction module through the second connection module to extract features. At the same time, the image features output by the first universal inverted bottleneck (UIB) layer are spliced ​​with the image features output by the third universal inverted bottleneck (UIB) layer through the first upsampling module (Upsample), and then output to the third feature extraction module through the third connection module to extract features and then output to the head network to form a second feature map, which is then output to the second detection module (Detect) for object detection. At the same time, the second feature map is fed back to the first connection module through the first convolution module (Conv) to strengthen the first feature map.

[0132] The image features output by the second separable convolution Convbn layer are output to the fourth feature extraction module (C2f) through the fourth connection module to extract features. At the same time, the image features output by the third universal inverted bottleneck (UIB) layer are spliced ​​with the image features output by the second separable convolution Convbn layer through the second upsampling module (Upsample), and then output to the fourth feature extraction module (C2f) through the fourth connection module to extract features and then output to the head network to form a third feature map, which is then output to the third detection module (Detect) for object detection. At the same time, the third feature map will be fed back to the third connection module through the second convolution module (Conv) to strengthen the second feature map.

[0133] Compared with traditional charging piles, mobile shared umbrella charging piles can monitor the power load of the area in real time. At the same time, mobile shared umbrella charging piles have charging powers of 20KW, 40KW and 60KW. Combined with fuzzy reasoning algorithm, it can effectively adjust the charging power by suggesting different charging powers to users. Figure 3 As shown, firstly, the current, voltage, temperature and other parameters of the transformer load in the substation are collected through sensors, and then the peak, valley and normal periods are judged through the fuzzy inference algorithm. The user is advised to choose different charging powers based on the judged peak, valley and normal periods. When it is the peak of electricity consumption, the user is advised to use the low power of 20KW charging gun for charging. When it is the peak of electricity consumption, the user is advised to use the power of 20KW and 40KW for charging. When it is the low power consumption, the user is reminded that it is the low power consumption and any power can be used for charging. The user is advised to use the high power of 60KW charging gun for charging. In this way, the peak-valley difference of electricity consumption can be reduced, the load rate of the transformer can be adjusted, and the user can also enjoy the relevant preferential policies for charging during the valley period, thereby realizing orderly electricity consumption, helping to reduce the peak and fill the valley, and facilitating the safe and stable operation of the power grid.

[0134] The calculation process of fuzzy inference algorithm:

[0135] The Mamdani type fuzzy inference method is adopted, using load current I, load power P, and load temperature T as input parameters, and the output results are peak power consumption, level power consumption peak and valley power consumption.

[0136] The load power is calculated as:

[0137] (1)

[0138] P is the load power; V is the load voltage; I is the load current; is the power factor.

[0139] The following fuzzy rules are established:

[0140] First, according to the ratio of each parameter input value to the rated value, the load current I is divided into three levels, namely, reaching the rated current small, reaching the rated current medium, and reaching the rated current large. The load power P is divided into three levels, namely, reaching the rated power small, reaching the rated power medium, and reaching the rated power large. The load temperature T is divided into three levels, namely, reaching the rated temperature small, reaching the rated temperature medium, and reaching the rated temperature large.

[0141] Then the fuzzy subset of the input variable I is {rated current small, rated current medium, rated current large}, abbreviated as {A, B, C,}, and the domain is [0%, 100%] (such as Fig. 9 As shown); the fuzzy subset of the input variable P is {rated power small, rated power medium, rated power large}, abbreviated as {E, F, G}, and the domain is [0%, 100%] (such as Fig.10 As shown); the fuzzy subset of load temperature T is {rated temperature small, rated temperature medium, rated temperature large}, abbreviated as {O, Q, W}, and the domain is [0%, 100%] (such as Fig.11 As shown); the fuzzy subset of the output variable H is {peak power consumption, level power consumption, valley power consumption}, abbreviated as {X, Y, Z}, and the domain is [0,10] (such as Fig.12 As shown in Figure 2), all variables use triangular membership functions, as shown in the following formula:

[0142] (2)

[0143] Where x is the input value, and a, b, and c are the boundary values ​​of the input and output parameters.

[0144] Establish a fuzzy rule base. The selection principle of the fuzzy rule base is: if (I) i and (P) i and(T) i then(H) i ,i=1,2,3,...,M, M is the total number of fuzzy rules. According to the daily experience of transformer load conditions, 27 fuzzy rules are finally determined as shown in Table 1.

[0145] Table 1 Fuzzy rules

[0146]

[0147] The formulation of fuzzy rules in Table 1 is based on the following principles:

[0148] (3)

[0149] Where R is the evaluation index; when 0.42≥R≥0.32, the load type is low power consumption; when 0.52≥R>0.42, the load type is high power consumption; when 0.78≥R>0.52, the load type is high power consumption;

[0150] The algorithm combination process is as follows Fig.13 As shown:

[0151] The input parameters I, P, and T are fuzzified, and the output parameter H is fuzzified; after the fuzzy rule base, reasoning and synthesis are performed, and then the parameters after reasoning and synthesis are defuzzified to output the type of load identification.

[0152] like Figure 4 As shown, based on the above-mentioned vehicle charging method, the present invention also discloses a mobile shared umbrella-shaped charging pile, including: a charging pile main pole 1, a support unit, a pneumatic pole 4, a charging pole unit, a camera 14 and a charging gun 15;

[0153] A base with a pulley is provided at the bottom of the charging pile main pole 1;

[0154] The support unit is arranged on the main pole 1 of the charging pile;

[0155] The charging rod unit is rotatably mounted on the top of the charging pile main rod 1;

[0156] One end of the pneumatic rod 4 is mounted on the support unit, and the other end is in contact with the charging rod unit, so as to adjust the angle of the charging rod unit;

[0157] One end of the charging gun 15 is connected to the charging pile main pole 1 through a charging line 10, and the other end is placed on the charging pile main pole 1;

[0158] The camera 14 is mounted on the main pole 1 of the charging pile.

[0159] like Figure 5 As shown, in some embodiments, a protective cover is provided around the gas pressure rod 4 to protect it from damage by the external environment. It also prevents dust, dirt, liquid, etc. from entering the gas pressure rod 4, thereby extending its service life and maintaining its stable performance. At the same time, the protective cover can also reduce the wear and corrosion of the gas pressure rod 4 and improve the reliability of the equipment.

[0160] The present invention designs an umbrella-shaped charging pile for irregular parking areas, which occupies less space, is flexible and convenient, and can be moved and shared, so that the charging device can be easily installed, configured flexibly, and used conveniently. In the case of irregular parking positions in old communities, the mobile shared umbrella-shaped charging pile of the present invention can charge new energy vehicles in any parking space by changing the position of the charging gun 15 through the charging rod 9, and one charging pile can serve multiple parking spaces.

[0161] The main pole 1 of the charging pile is equipped with a camera 14, which can be used for real-time monitoring and safety management to monitor the charging process and prevent theft, damage or improper operation. At the same time, the camera 14 can also help record and analyze charging behavior to optimize the efficiency and maintenance service of the charging pile. It is mainly used to identify the position of the charging port, rotate the main pole 1 of the charging pile and adjust the angle of the charging pole 9 to make the charging gun 15 to the appropriate charging position.

[0162] In some embodiments, the support unit includes a first support rod 2, a second support rod 3, a first support rod fixing device 5 and a second support rod fixing device 6;

[0163] One end of the first support rod 2 is fixedly mounted on the charging pile main rod 1 through a first support rod fixing device 5, and the other end is connected to one end of the second support rod 3;

[0164] The other end of the second support rod 3 is fixedly mounted on the charging pile main rod 1 through a second support rod fixing device 6;

[0165] The bottom end of the gas pressure rod 4 is installed on the second support rod 3;

[0166] The first support rod 2, the second support rod 3 and the charging pile main rod 1 form a triangular structure with greater stability.

[0167] In some embodiments, the charging rod unit includes a counterweight 7, a charging rod connecting device 8 and a charging rod 9;

[0168] The charging rod 9 is rotatably connected to the top of the charging pile main rod 1 through the charging rod connecting device 8;

[0169] A counterweight 7 is provided at one end of the charging rod 9;

[0170] The angle between the charging pole 9 and the main pole 1 of the charging pile is in the range of 110-150°. The head of the charging pole 9 is slightly higher, which helps rainwater or other liquids to flow naturally to the end of the pole, avoids water accumulation, reduces the risk of corrosion and damage, and helps to enhance the visibility of the charging pile, making it easier for users to find the charging position, especially at night or in poor visibility. It can reduce the accumulation of debris (such as fallen leaves, dust, etc.) on the charging pole 9, which helps to keep the equipment clean and running well. This range can make the charging pile structure more stable and reduce the impact of external factors such as wind on the charging pile.

[0171] The charging pile is provided with a first support rod fixing device 5, a second support rod fixing device 6, a charging rod connecting device 8 and a camera 14. The first support rod 2 and the second support rod 3 are connected by a hinge for easy disassembly and installation.

[0172] The second support rod 3 is connected to the pneumatic rod 4 , and the pneumatic rod 4 is connected to the charging rod 9 , so that the angle of the charging rod 9 can be adjusted by adjusting the pneumatic rod 4 , thereby adjusting the position of the charging gun 15 .

[0173] The charging rod 9 is connected to the charging pile main rod 1 through the charging rod connecting device 8, which can adjust the up and down angles of the charging rod 9. There is a counterweight 7 at the tail of the charging rod 9, which is used to adjust the center of gravity and stability of the charging rod 9. It can help balance the weight of the charging rod 9, reduce shaking or tilting, and thus improve the accuracy and stability of charging.

[0174] like Figure 7 As shown, in some embodiments, the mobile shared umbrella-shaped charging pile further includes: a solar panel 11, a guardrail 12 and a cable clip 13;

[0175] The guardrail 12 is installed on the periphery of the base;

[0176] The solar panel 11 is installed on the guardrail 12;

[0177] The cable clip 13 is installed on the charging pile main pole 1, and the cable clip 13 is in a rectangular ring shape (such as Figure 6 Designing a cable clip 13 in the charging pile main pole 1 can firmly fix the cable in the charging pile main pole 1, preventing the cable from moving or getting loose during use, thereby reducing potential safety hazards and cable wear, extending the service life of the cable, and helping to neatly arrange the cables together to avoid cable entanglement, crossing or disorder, and facilitating maintenance and inspection.

[0178] The guardrail 12 is connected to the main pole 1 of the charging pile, which can effectively prevent vehicles or other objects from hitting the charging pile and reduce damage or failure of the charging pile caused by collision. This is particularly important for charging piles located in parking lots or areas with large traffic volume. At the same time, it can avoid safety problems caused by improper operation or accidents, and can also protect the cables, connectors and other equipment of the charging pile from external interference, damage or malicious destruction, thereby extending the service life of the equipment. A solar panel 11 is installed on the guardrail 12, the purpose of which is to use solar energy so that the charging pile can generate part or all of the required electricity, thereby reducing dependence on traditional grid electricity. This helps to reduce electricity costs and reduce operating costs. Providing an additional power source through the solar panel 11 can alleviate the load on the grid, reduce the impact of power outages on the operation of the charging pile, improve the overall reliability and stability of the charging pile, and provide power for additional functions of the charging pile (such as lighting, display screens or communication systems), making the charging pile more comprehensive.

[0179] like Figure 8As shown, in some embodiments, the mobile shared umbrella-shaped charging pile further includes: a first limiter 16, a second limiter 17 and a third limiter 18;

[0180] The charging pile main pole 1 comprises an upper pole and a lower pole, which are rotatably connected;

[0181] The first stopper 16 is fixedly mounted on the outer wall of the bottom of the upper rod; the second stopper 17 is mounted on the inner wall of the top of the lower rod through a spring and has two states: extended and retracted; the third stopper 18 is fixedly mounted on the inner wall of the top of the lower rod;

[0182] The first stopper 16 is disposed between the second stopper 17 and the third stopper 18;

[0183] When the charging pile main pole 1 is in gear position 1, the rotation angle of the charging pile main pole 1 is 0-160°;

[0184] When the main pole 1 of the charging pile is in the second gear, the rotation angle of the main pole 1 of the charging pile is 0-200°. When the main pole 1 of the charging pile is in the first gear, when adjustment is needed, the second limiter 17 is retracted, and when the first limiter 16 passes through the second limiter 17 and then resets, the second gear is reached. The two gears are adapted to different working conditions. By designing the limiter, it is possible to prevent the damage caused by the twisting of the cable in the column due to excessive rotation of the main pole 1 of the charging pile, reduce the risk of collision with surrounding objects, reduce mechanical wear and failure caused by excessive rotation, extend the service life of the equipment, and help the equipment to more easily control the rotation angle during maintenance or adjustment, ensuring that the equipment can return to normal working condition.

[0185] Exemplarily, the stopper can be a rectangular block or a cylinder. The second stopper 17 is a movable rectangular block, and the extension and retraction of the rectangular block is controlled by electromagnetic force. Similar to the working principle of a relay, the rectangular block is in an extended state under normal conditions by a spring, and is in a retracted state under electromagnetic force when powered.

[0186] The charging pile main pole 1, the first support pole 2, the second support pole 3, the pneumatic pole 4, the charging pole 9 and the guardrail 12 together constitute an overall umbrella-shaped frame. The umbrella-shaped frame provides good force performance, can effectively disperse the load, enhance the overall stability and wind resistance, and is particularly suitable for outdoor environments. The umbrella-shaped design usually occupies less ground space, and can more efficiently layout charging piles in urban environments, thereby improving space utilization.
