Description

Technical Field

[0001] The present invention relates to the technical field of source-grid-load-storage, and specifically refers to a source-grid-load-storage charging and swapping integrated device based on local green electricity. Background Art

[0002] Under the background of the current energy structure transformation and technological progress, the utilization of source-grid-load-storage (source-grid-load-storage integration) and green electricity (green power) is becoming the key to promoting the efficient utilization of renewable energy. The source-grid-load-storage technology realizes the optimal allocation and efficient management of energy by integrating power generation, power transmission, energy storage, and power consumption, while green power represents the extensive application of clean energy such as wind energy and solar energy. Together, they support a low-carbon and environmentally friendly energy future. However, in the integrated application of source-grid-load-storage and green power in the existing technology, especially in the charging and swapping management of energy storage batteries, there are some challenges and defects.

[0003] For example, when the existing charging and swapping integrated device charges and swaps the energy storage battery, an important problem it faces is the lack of real-time response and adjustment ability to the change of the battery state. During the charging and swapping process, key parameters such as the voltage, current, and temperature of the battery will change. However, in actual application, the existing device is difficult to monitor the condition of the energy storage battery in real time after charging and swapping, so it is impossible to obtain the charging demand parameters of the energy storage battery in time after charging and swapping, resulting in difficulty in optimizing its charging process, which may damage the battery, thus affecting the service life and safety of the energy storage battery and restricting the use of the device. Summary of the Invention

[0004] The purpose of the present invention is to provide a source-grid-load-storage charging and swapping integrated device based on local green electricity to solve one of the above problems existing in the prior art.

[0005] Specifically, the present invention is realized through the following technical solutions:

[0006] A source-grid-load-storage charging and swapping integrated device based on local green electricity includes a power source side, a power grid side, an energy storage side, and a user load side. The power source side generates green electric energy based on a wind-solar power generation unit and outputs it to the power grid side; the power grid side transmits the green electric energy to the user load side and the energy storage side based on a power transmission network, and the user load side is an electricity consumption terminal; the energy storage side is used to store the surplus electric energy transported by the power grid side and consumed by the user load side, and dynamically supply power to supplement it based on the power consumption demand of the user load side. The energy storage side further includes:

[0007] A packaging shell, which is fixedly arranged and has a cavity inside. The two sides inside the cavity are divided into a charging area and a swapping area;

[0008] The energy storage and charging unit includes a number of energy storage batteries located in the charging area and installed on a charging rack in the charging area. The charging rack is provided with a number of charging slots corresponding to the energy storage batteries from top to bottom. The number of energy storage batteries are correspondingly inserted into the charging slots and connected to the charging modules in the charging slots. The charging modules are connected to the grid side through lines;

[0009] The battery swapping mechanism is arranged in the battery swapping area and completes the battery swapping work by grasping and replacing the energy storage batteries on the charging rack. A battery swapping door is opened on one side of the battery swapping area. Through the battery swapping door, the grasped and replaced energy storage batteries are taken out;

[0010] The dynamic adjustment unit is arranged in the charging area and includes a monitoring module and an adjustment module. The monitoring module is used to collect the state change data of the energy storage battery during charging and swapping, and transmit it to a data processor located above the charging area for processing to output the charging demand parameters of the energy storage battery after the current battery swapping. After receiving the charging demand parameters of the current energy storage battery output by the data processor, the adjustment module adjusts the charging parameters of the charging module of the corresponding energy storage battery in real time.

[0011] It should be noted that by introducing the dynamic adjustment unit, including the monitoring module and the adjustment module, this solution can collect the state change data of the energy storage battery during charging and swapping in real time and output the charging demand parameters of the energy storage battery after the current battery swapping. It effectively solves the technical problem that the existing technology cannot obtain the charging demand parameters of the energy storage battery after charging and swapping in time, which makes it difficult to optimize its charging process and may damage the battery. Therefore, it greatly improves the use effect and service life of the energy storage battery, and greatly improves the use effect of the device. At the same time, it can more accurately evaluate the battery condition, provide more reasonable charging parameters for the charging module, realize the precise control of the energy storage battery, and effectively improve the integration application performance and reliability of the source-grid-load-storage and green power technologies.

[0012] Specifically, the monitoring module is correspondingly arranged in a number of charging slots and collects the state change data of the energy storage battery in the charging slots during charging and swapping. The monitoring module includes a temperature sensor, a current sensor and a voltage sensor. The temperature sensor is installed on the side wall of the charging slot, and one end of its temperature measuring part is close to the energy storage battery for collecting the temperature change data of the energy storage battery during charging and swapping. The current sensor and the voltage sensor are integrally arranged on the charging module in the charging slot for collecting the current change data and voltage change data of the charging module when the energy storage battery is charging and swapping.

[0013] The data processor is respectively connected to the temperature sensor, current sensor, and voltage sensor in a signal manner, and after receiving the temperature change data, current change data, and voltage change data collected by the temperature sensor, current sensor, and voltage sensor, it performs calculation and processing on them. The calculation and processing process of the data processor includes:

[0014] Step 1: Synchronize the time stamps of the received temperature change data, current change data, and voltage change data, and perform consistency processing on them through cleaning, duplicate removal, and format conversion;

[0015] Step 2: Sample-align the temperature change data, current change data, and voltage change data that have been subjected to consistency processing in Step 1;

[0016] Step 3: Adopt a weighted average algorithm to perform feature data fusion processing on the sample-aligned temperature change data, current change data, and voltage change data, and output a unified feature data set;

[0017] Step 4: Perform calculation and processing on the feature data set through a storage battery charging evaluation model, evaluate the status parameters of the storage battery currently in the charging or swapping state, and then calculate and output the charging demand parameters of the current storage battery based on the status parameters of the storage battery currently in the charging or swapping state.

[0018] Furthermore, in Step 3, the feature data fusion processing satisfies the following calculation process:

[0019] ;

[0020] Among them, represents the temperature change data at time point , represents the current change data at time point , represents the voltage change data at time point , , , respectively represent the weights of the temperature change data, current change data, and voltage change data, represents the total number of time points, represents the output feature data set.

[0021] Preferably, in Step 4, the storage battery charging evaluation model is constructed based on a Gaussian process regression model, and the Gaussian process regression model includes a feature input layer, a kernel function calculation layer, and a result output layer;

[0022] The feature input layer is used to extract the dynamic change data source points in the feature data set as the model input into the kernel function calculation layer;

[0023] The kernel function calculation layer defines the similarity measure of the dynamically changing data source points based on the dynamically changing data source points that are the model inputs, calculates and infers the dependency relationship output between the dynamically changing data feature points by constructing a covariance matrix, and then, after calculating the dependency relationship between the dynamically changing data feature points output based on the covariance matrix, iteratively calculates the posterior probability distribution of the condition parameters of the energy storage battery currently in the charging or swapping state, and performs matching comparison based on the calculated posterior probability distribution of the condition parameters and the expected threshold to evaluate and obtain the condition parameters of the energy storage battery currently in the charging or swapping state and output them;

[0024] After receiving the condition parameters of the energy storage battery currently in the charging or swapping state output by the kernel function calculation layer, the result output layer comprehensively calculates and outputs the charging demand parameters of the energy storage battery currently in the charging or swapping state based on the condition parameters of the energy storage battery and the charging rate requirement.

[0025] In the above solution, the dynamic adjustment unit is the core of this solution. It dynamically adjusts the charging parameters by monitoring the state changes of the energy storage battery during the charging or swapping process in real time to optimize the usage effect and lifespan of the battery. Specifically, the monitoring module in the dynamic adjustment unit includes temperature sensors, current sensors, and voltage sensors installed in the charging slot, so that it can collect the temperature change data, current change data, and voltage change data of the energy storage battery in real time during the charging or swapping process, and the collected data is transmitted to the data processor. The data processor first synchronizes the time stamps of the received data to ensure that all data points are consistent in time. Subsequently, the data is processed for consistency through cleaning, duplicate removal, and format conversion to eliminate noise and outliers, and the data in different formats is unified into the same format. Then, the preprocessed data enters the feature data fusion processing stage, and the weighted average algorithm is used to fuse the sampled and aligned data to form a unified feature data set (it should be further noted that when performing data fusion processing, by comprehensively considering the importance (i.e., weight) of the temperature, current, and voltage data, a comprehensive weighted average value is calculated to accurately reflect the current state of the battery). Then, the obtained feature data set is subsequently applied to the charging evaluation model, which is constructed based on the Gaussian process regression algorithm. It analyzes the dynamically changing data source points, defines the similarity measure between data points, constructs a covariance matrix, and calculates the posterior probability distribution to evaluate the condition parameters of the energy storage battery in the current charging or swapping state, and calculates and obtains the charging demand parameters of the energy storage battery in the current charging or swapping state based on the condition parameters. Finally, the adjustment module adjusts the charging parameters of the charging module in real time according to the charging demand parameters output by the data processor. This may include adjusting the charging current, voltage, or charging strategy to ensure that the battery is charged in the optimal state, avoiding overcharging or undercharging, thereby extending the lifespan of the energy storage battery and improving the charging efficiency.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] 1. By introducing a dynamic adjustment unit, including a monitoring module and an adjustment module, the present invention can collect the state change data of the energy storage battery during charging and swapping in real time, and output the charging demand parameters of the energy storage battery after the current swapping. It solves the problem in the prior art that the charging parameters cannot be adjusted in real time, thereby improving the use effect and service life of the energy storage battery. At the same time, by adopting the weighted average algorithm and the Gaussian process regression model, it can more accurately evaluate the battery condition, provide more reasonable charging parameters for the charging module, realize the precise control of the energy storage battery, effectively improve the integration application performance and reliability of the source-network-load-storage and green power technologies, optimize the charging process, and improve the charging efficiency and the service life of the device;

[0028] 2. By setting a charging terminal housing and a plugging ring, the present invention provides double physical protection for the charging connector. The charging terminal housing is located on the side wall of the charging slot, which can resist external impacts and damages, and protect the charging connector from physical damage. The plugging ring is sleeved outside the docking rod, further enhancing the abrasion resistance and impact resistance of the docking rod, effectively preventing the damage of the docking rod during daily use, and prolonging the service life of the charging module. Further, in the annular gap formed between the plugging ring and the docking rod, a plurality of dust cleaning nozzles are provided at positions corresponding to the charging interface and are distributed in an annular array. When the charging plug rod is inserted into the charging interface, the extrusion part at its front end is in interference fit with the sealing gasket, squeezing the air bag inside the sealing gasket, so that the gas inside the air bag enters the dust cleaning nozzle through the air pipeline and is ejected from the nozzle to blow the charging interface. This automatic dust cleaning mechanism can timely remove the dust and impurities at the charging interface, keep the charging contact surface clean, thereby improving the charging efficiency and reliability. In addition, by providing a sealing gasket at a position close to the end of the inner ring surface of the plugging ring, and an air bag is provided inside the sealing gasket. The design of the air bag not only provides an additional sealing effect to prevent dust and moisture from invading the charging interface, but also provides a stable support and buffer for the charging plug rod through the elastic action of the air bag, ensuring the tight fit between the charging plug rod and the charging interface, and enhancing the stability and reliability of the charging connection;

[0029] 3. In the present invention, support plates are symmetrically arranged on both sides inside the charging slot, and guiding grooves are formed on the support plates. These guiding grooves are arranged along the length direction of the support plates, communicate with the outside at one end, and are provided with blocking baffles at the other end, ensuring the precise guiding and positioning of the energy storage battery during the installation process. Meanwhile, a plurality of guiding rollers are arrayed in the guiding grooves, facilitating the more stable movement of the grasping structure when grasping the energy storage battery for charging and discharging. Further, in this solution, when the energy storage battery is installed in place, the plug connector at one end of the clamping block is inserted into the socket groove, and magnetic connection is achieved through the connecting piece and the magnetic part at the middle position of the groove bottom, thereby providing a stable magnetic attraction force. At the same time, the wedge-shaped inclined surfaces on both sides of the plug connector guide and cooperate with the top blocks in the corresponding cavities. That is, during the gradual insertion of the plug connector, the plug connector can jack up the top blocks through the wedge-shaped inclined surfaces on both sides, thereby promoting the movement of the top blocks under the guidance of the plug connector to push the flip plate in the cavity to flip. Furthermore, the flipping action of the flip plate drives the limit block to insert into the limit groove at the other end of the clamping block to complete the limit fixation of the clamping block, thereby promoting the stable installation of the energy storage battery to ensure the installation and fixation of the energy storage battery and prevent its displacement, which may otherwise affect the normal charging and discharging use of the energy storage battery.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0042] The features and performance of the present invention will be further described in detail below in combination with the embodiments. Embodiment

[0043] Please refer to the appendix Figures 1 to 2, this embodiment provides a source-grid-load-storage-charging and swapping integrated device based on local green electricity, including a power source side, a grid side, a storage side, and a user load side. The power source side generates green electricity based on a wind-solar power generation unit and outputs it to the grid side; the grid side transmits the green electricity to the user load side and the storage side based on a power transmission network, and the user load side is an electricity consumption terminal; the storage side is used to store the surplus electricity transmitted by the grid side and consumed by the user load side, and dynamically supply power to supplement it based on the power consumption demand of the user load side. The storage side further includes:

[0044] An encapsulation housing 1, fixedly arranged, and having a cavity 117 inside it. The two sides inside the cavity 117 are respectively a charging area 11 and a swapping area 10;

[0045] A charging and storage unit, including a plurality of energy storage batteries 111 located in the charging area 11 and installed on a charging rack 110 in the charging area 11. The charging rack 110 is provided with a plurality of charging slots corresponding one-to-one with the energy storage batteries 111 from top to bottom. The plurality of energy storage batteries 111 are correspondingly inserted into the charging slots and connected to the charging modules 112 in the charging slots. The charging modules 112 are connected to the grid side through lines;

[0046] A swapping mechanism 100, arranged in the swapping area 10, and completes the swapping work by grasping and replacing the energy storage batteries 111 on the charging rack 110. A swapping door 12 is opened on one side of the swapping area 10, and through the swapping door 12, the grasped and replaced energy storage batteries 111 are taken out;

[0047] A dynamic adjustment unit, arranged in the charging area 11, including a monitoring module and an adjustment module. The monitoring module is used to collect the state change data of the energy storage batteries 111 during charging and swapping, and transmit it to a data processor 23 located above the charging area 11 for processing, so as to output the charging demand parameters of the energy storage batteries 111 after the current swapping. After receiving the current charging demand parameters of the energy storage batteries 111 output by the data processor 23, the adjustment module adjusts the charging parameters of the charging modules 112 of the corresponding energy storage batteries 111 in real time.

[0048] It should be understood that in the prior art, due to the slight differences in the manufacturing and use processes of the energy storage battery 111, these differences will gradually accumulate during long-term charge and discharge cycles, resulting in the inconsistency of the performance of the energy storage battery 111. Without dynamic adjustment, this inconsistency will cause some energy storage batteries 111 to be overcharged or over-discharged, thereby accelerating the aging of the energy storage battery 111, reducing the performance and service life of the energy storage battery 111, and increasing safety hazards, such as the risk of thermal runaway caused by local overheating. At the same time, the fluctuations in the grid load require the energy storage side to be able to respond quickly to maintain the stability of the grid. If the energy storage side cannot dynamically adjust the charging parameters according to the real-time grid demand and battery state, it will lead to energy waste and low efficiency, and cannot effectively balance the grid load, affecting the reliability of power supply.

[0049] Therefore, the dynamic adjustment unit of this embodiment can dynamically adjust the charging parameters according to the real-time monitoring of the battery state, which plays a crucial role in maintaining the healthy state of the battery, improving the energy utilization efficiency, ensuring the stability and safety of the grid. It can optimize the charge and discharge process, reduce battery stress, extend the life of the energy storage battery 111, and at the same time improve the adaptability and response speed of the energy storage side to grid changes, ensuring the continuity and reliability of power supply.

[0050] Specifically, as Figure 3 shown, the monitoring module is correspondingly arranged in a plurality of charging slots, and collects the state change data of the energy storage battery 111 in the charging slots during charging and discharging. The monitoring module includes a temperature sensor 20, a current sensor 21, and a voltage sensor 22. The temperature sensor 20 is installed on the side wall of the charging slot, and one end of its temperature measuring part is close to the energy storage battery 111, and is used to collect the temperature change data of the energy storage battery 111 during charging and discharging. The current sensor 21 and the voltage sensor 22 are integrally arranged on the charging module 112 in the charging slot, and are used to collect the current change data and voltage change data of the charging module 112 during charging and discharging of the energy storage battery 111.

[0051] For this embodiment, the temperature change data, current and voltage change data are crucial for evaluating the health status and charging efficiency of the battery. Since temperature monitoring is crucial for preventing battery overheating and thermal runaway, as the battery generates heat during the charging and discharging process, improper temperature control may lead to a decline in the performance of the energy storage battery 111 or even damage. The change data of current and voltage are crucial for evaluating the health status and charging efficiency of the battery, which can accurately indicate the change of the internal performance state of the battery. Therefore, in this embodiment, in order to facilitate the real-time monitoring of the key parameters of the energy storage battery 111, the monitoring module (including the temperature sensor 20, current sensor 21 and voltage sensor 22) is respectively installed in the charging slot, so as to facilitate its real-time monitoring and acquisition of the relevant key parameters of the energy storage battery 111, thereby facilitating the evaluation and analysis of the state of the energy storage battery 111 during charging and discharging, and further facilitating the precise control and optimization of the energy storage battery 111 during charging and discharging, thus improving the safety and efficiency of the energy storage side, and ensuring the safe use of the device and extending its life.

[0052] Based on the above embodiment, the data processor 23 is respectively connected to the temperature sensor 20, current sensor 21 and voltage sensor 22 in a signal connection, and after receiving the temperature change data, current change data and voltage change data collected by the temperature sensor 20, current sensor 21 and voltage sensor 22, it performs calculation and processing on them. The calculation and processing process of the data processor 23 includes:

[0053] Step 1, synchronize the time stamps of the received temperature change data, current change data and voltage change data, and perform consistency processing on them through cleaning, duplicate removal and format conversion;

[0054] Step 2, perform sampling alignment on the temperature change data, current change data and voltage change data that have been subjected to the consistency processing in Step 1;

[0055] Step 3, adopt a weighted average algorithm to perform feature data fusion processing on the temperature change data, current change data and voltage change data after sampling alignment and output a unified feature data set;

[0056] Step 4, perform calculation and processing on the feature data set through the charging evaluation model of the energy storage battery 111, evaluate the status parameters of the energy storage battery 111 currently in the charging and discharging state, and then calculate and output the charging demand parameters of the current energy storage battery 111 based on the status parameters of the energy storage battery 111 currently in the charging and discharging state.

[0057] It should be shown that in this embodiment, through the refined working process of the data processor 23, the accurate monitoring and optimized management of the charging and swapping states of the energy storage battery 111 are realized. The data processor 23 is first connected to the temperature sensor 20, the current sensor 21, and the voltage sensor 22 in signal connection to ensure that the key parameters of the energy storage battery 111 during the charging and swapping process can be comprehensively collected. Specifically, the technical solution disclosed in this embodiment significantly improves the battery performance and the efficiency on the energy storage side through a series of innovative data preprocessing and analysis technologies. First, the data processor 23 ensures the temporal consistency of the data collected from different sensors through the timestamp synchronization technology, which is a prerequisite for data fusion. Then, the data cleaning and format conversion technologies are applied to eliminate noise and outliers and unify the data in different formats for subsequent processing. Through this step, not only the data quality is improved, but also an accurate data basis is provided for feature extraction and model training. After the sampling alignment, the weighted average algorithm is used to perform feature data fusion processing on the data. This algorithm takes into account the accuracy and importance of the data from different sensors and optimizes the data fusion result by assigning different weights, thereby outputting a unified set of feature data. In addition, in this embodiment, the charging evaluation model of the energy storage battery 111 is used to evaluate the energy storage battery 111 during charging and swapping, which can provide probability prediction and uncertainty estimation. This is particularly important for battery health management and predictive maintenance. It enhances the accuracy and reliability of the state evaluation of the energy storage battery 111 and can calculate the charging demand parameters of the energy storage battery 111 to dynamically adjust the charging strategy, avoid overcharging or undercharging, reduce the damage to the energy storage battery 111, and thus improve the usage efficiency and lifespan of the energy storage battery 111.

[0058] Furthermore, based on the above embodiment, in step 3, the feature data fusion processing satisfies the following calculation process:

[0059] ;

[0060] Wherein, represents the temperature change data at the time point , represents the current change data at the time point , represents the voltage change data at the time point , , , respectively represent the weights of the temperature change data, the current change data, and the voltage change data. It should be noted that the setting of the weights is based on the importance and reliability of each parameter's influence on the battery state, and in the specific weight allocation, it can be adjusted according to the importance of each data source's influence on the battery state. represents the total number of time points. Represents the set of characteristic data for output.

[0061] It should be noted that the weighted average algorithm in the above embodiments can more accurately evaluate the state of the energy storage battery 111. Specifically, it can be dynamically adjusted according to the characteristics and importance of different data, so as to achieve higher accuracy and efficiency in the data fusion process, thereby providing more accurate input data for the charging evaluation model, and then calculating more reasonable charging demand parameters, optimizing the charging process, so as to improve the use efficiency and life of the energy storage battery 111.

[0062] As a preferably feasible implementation, in step 4, the charging evaluation model of the energy storage battery 111 is constructed based on the Gaussian process regression model, and the Gaussian process regression model includes a feature input layer, a kernel function calculation layer, and a result output layer;

[0063] The feature input layer is used to extract the dynamic change data source points in the set of characteristic data as the model input into the kernel function calculation layer;

[0064] The kernel function calculation layer defines the similarity measure of the dynamic change data source points based on the dynamic change data source points as the model input, and calculates and infers the dependency relationship output between the dynamic change data feature points by constructing a covariance matrix. Then, after calculating the dependency relationship between the dynamic change data feature points output based on the covariance matrix, the posterior probability distribution of the condition parameters of the energy storage battery 111 currently in the charging and swapping state is calculated iteratively, and based on the calculated posterior probability distribution of the condition parameters and the expected threshold, a matching comparison is made to evaluate and obtain the condition parameters of the energy storage battery 111 currently in the charging and swapping state and output them;

[0065] After receiving the condition parameters of the energy storage battery 111 currently in the charging and swapping state output by the kernel function calculation layer, the result output layer comprehensively calculates the charging demand parameters of the energy storage battery 111 currently in the charging and swapping state based on the condition parameters of the energy storage battery 111 and the charging rate demand and outputs them.

[0066] It should be noted that in the construction of the charging evaluation model of the energy storage battery 111 in this embodiment, a Gaussian process regression model is adopted. This model includes a feature input layer, a kernel function calculation layer, and a result output layer. The feature input layer extracts the dynamic change data source points in the feature data set. The kernel function calculation layer defines the similarity measure based on these data source points and calculates the dependence relationship between the dynamic change data feature points by constructing a covariance matrix. This process not only provides the probability prediction of the battery state but also quantifies the uncertainty of the prediction. After receiving the battery condition parameters output by the kernel function calculation layer, the result output layer comprehensively calculates and outputs the charging demand parameters based on these parameters and the charging rate requirement, so as to more accurately predict the state change of the energy storage battery 111, thereby dynamically adjusting the charging strategy, avoiding overcharging or undercharging, reducing the damage to the energy storage battery 111, and improving the use efficiency and service life of the energy storage battery 111.

[0067] In addition, it should be noted that this solution uses the Gaussian process regression model for the charging evaluation of the energy storage battery 111. It can handle uncertainty and nonlinear problems. By defining the similarity measure between data points and constructing a covariance matrix, it provides a powerful tool for evaluating battery condition parameters. Compared with traditional machine learning methods, it can provide probability prediction and uncertainty estimation, which is particularly important for battery health management and predictive maintenance. That is to say, the technical solution disclosed in this embodiment comprehensively applies advanced technologies such as timestamp synchronization, data cleaning, feature data fusion, and Gaussian process regression model. It not only improves the accuracy and efficiency of data processing but also enhances the accuracy and reliability of the state evaluation of the energy storage battery 111. It can dynamically adjust the charging strategy, avoid overcharging or undercharging, reduce the damage to the energy storage battery 111, and thus improve the use efficiency and service life of the energy storage battery 111.

[0068] Based on the above embodiments, further, please refer to Figure 3, the charging module 112 includes a charging terminal housing 1120 and a charging connector. The charging terminal housing 1120 is located on the side wall of the charging slot. The charging connector is installed on one side of the charging terminal housing 1120 corresponding to the energy storage battery 111. The charging connector includes a protruding docking rod 1121 and a charging interface 11210 opened at one end of the docking rod 1121. A protection component is further provided around the docking rod 1121 near the position of the charging interface 11210. The protection component includes a plugging ring 1122 sleeved outside the docking rod 1121. One end of the plugging ring 1122 is closer to the energy storage battery 111 than the end of the docking rod 1121. An annular gap is formed between the inside of the plugging ring 1122 and the docking rod 1121. A plurality of dust cleaning nozzles 1123 distributed in an annular array are provided at the position corresponding to the charging interface 11210 in the gap. A sealing gasket 1124 is further provided at the inner ring surface of the plugging ring 1122 near its end. An air charging bag 1125 is provided inside the sealing gasket 1124. The air charging bag 1125 is connected to the dust cleaning nozzles 1123 through an air pipeline.

[0069] It should be understood that during long-term use, the charging interface 11210 is constantly exposed to the external environment. Inevitably, dust and debris will adhere to it. These accumulations will have a series of negative impacts on the charging process of the energy storage battery 111. First of all, dust may cause poor electrical contact, affecting the charging efficiency and even causing the charging process to interrupt. At the same time, the corrosive substances in the dust may damage the electronic components of the charging interface 11210, shortening its service life. In addition, the accumulation of dust may also affect the heat dissipation performance of the battery, causing the battery to overheat, which in turn affects the performance and safety of the battery. Particularly importantly, dust may also increase the internal resistance of the battery, affecting the battery's storage capacity and self-consumption ability. Over time, it may lead to a decline in the performance of the energy storage battery 111 and a shortening of its service life. Therefore, regularly cleaning the charging interface 11210 is crucial for maintaining the performance of the energy storage battery 111, extending the service life of the energy storage battery 111, and ensuring charging safety. In view of this, through the above structural design, this solution realizes the comprehensive protection and automatic dust cleaning function of the charging connector, improving the safety and efficiency of the charging process. That is, through the design of the charging terminal housing 1120 and the protection component, it effectively prevents damage to the charging connector caused by external factors, improving the safety of the charging process. The charging terminal housing 1120 is located on the side wall of the charging slot and can resist external impacts and damage, protecting the charging connector from physical damage. The plugging ring 1122 is sleeved outside the docking rod 1121, further enhancing the wear resistance and impact resistance of the docking rod 1121, effectively preventing damage to the docking rod 1121 during daily use, and extending the service life of the charging module 112. At the same time, in the annular gap formed between the plugging ring 1122 and the docking rod 1121, multiple dust cleaning nozzles 1123 are provided at positions corresponding to the charging interface 11210 and are distributed in an annular array, so as to blow the dust and impurities at the charging interface 11210 to keep the charging contact surface clean;

[0070] In addition, by providing a sealing gasket 1124 at a position near the end of the inner ring surface of the plugging ring 1122, and an air-filled bag 1125 is provided inside the sealing gasket 1124. The design of the air-filled bag 1125 not only provides an additional sealing effect to prevent dust and moisture from invading the charging interface 11210, but also provides a stable support and buffer for the charging plug 1126 through the elastic action of the air-filled bag 1125, ensuring a tight fit between the charging plug 1126 and the charging interface 11210, and enhancing the stability and reliability of the charging connection.

[0071] In this embodiment, preferably, a charging plug rod 1126 is provided on the side wall of the energy storage battery 111 corresponding to the charging module 112. A charging plug adapted to be plugged into the charging interface 11210 is provided at the front end of the charging plug rod 1126. And a protruding pressing part 11260 is provided outside the charging plug rod 1126. When the charging plug is inserted into the charging interface 11210 for plugging and matching, the pressing part 11260 is in interference fit with the sealing gasket 1124. In Figure 3 It is also shown.

[0072] In the above embodiment, when the energy storage battery 111 is being charged or replaced, when its charging plug rod 1126 is inserted into the charging interface 11210, the pressing part 11260 at its front end can be in interference fit with the sealing gasket 1124, squeezing the air bag 1125 inside the sealing gasket 1124, so that the gas inside the air bag 1125 enters the dust cleaning nozzle 1123 through the air pipeline and is ejected from the nozzle to blow the charging interface 11210. Thus, when the energy storage battery 111 is being installed for charging or replacement, automatic dust cleaning of the charging interface 11210 can be realized, ensuring that the dust and impurities at the charging interface 11210 can be removed in time, improving the cleanliness of the charging interface 11210, and thus enhancing the reliability and safety of the charging connection.

A plurality of guide rollers 1131 are also arranged in the two guide grooves 1130 along their length directions in an array;

[0074] At the positions of the guide grooves 1130 on the two support plates 113 corresponding to the bottom of the energy storage battery 111, clamping blocks 115 adapted to the guide grooves 1130 are further provided.

[0075] Based on the technical solution disclosed in this embodiment, by arranging a dedicated mounting member below the interior of the charging slot, stable support and precise positioning of the energy storage battery 111 are achieved. Since the mounting member is composed of support plates 113 symmetrically arranged on both sides of the bottom of the charging slot, and a guiding groove 1130 is provided on the upper part of the support plate 113 along the length direction of the support plate 113, one end of the guiding groove 1130 is connected to the outside, the other end is open, and a plurality of guiding rollers 1131 are arrayed inside, thereby ensuring that the energy storage battery 111 can smoothly move along the guiding groove 1130 to the designated position of the charging slot. At the same time, clamping blocks 115 adapted to the guiding groove 1130 are provided at the positions corresponding to the guiding grooves 1130 on the two support plates 113 at the bottom of the energy storage battery 111, which enables the battery to be accurately docked with the charging slot, improving the accuracy and efficiency of installation.

[0076] It should also be noted that, as shown in Figure 4 and Figure 5 a fastener for fastening the clamping block 115 at the bottom of the energy storage battery 111 is further provided inside the guiding groove 1130, and the fastener includes a plugging component and a clamping component;

[0077] The plugging component includes a plugging groove 1160 provided on the side surface of the blocking baffle 114 corresponding to the clamping block 115, and a magnetic attracting member 11600 is provided at the middle position of the bottom of the plugging groove 1160. At one end of the clamping block 115 corresponding to the plugging groove 1160, a plug head 1150 adapted to the plugging groove 1160 is provided. Wedge-shaped inclined surfaces are provided on both sides of the plug head 1150, and a connecting piece magnetically matched with the magnetic attracting member 11600 is connected at the contact position between the plug head 1150 and the plugging groove 1160;

[0078] The clamping component includes limit clamping blocks 1161 movably arranged at both sides of the open end of the guiding groove 1130, and limit grooves adapted to the limit clamping blocks 1161 are provided on both sides of one end of the clamping block 115 away from the plug head 1150;

[0079] Inside the two support plates 113 and at both sides of the guiding groove 1130, cavities 117 are provided. A turning plate 118 is hinged in the cavity 117. One end of the turning plate 118 in the length direction extends along the direction of the plugging groove 1160, and a top block 1180 extending into the plugging groove 1160 abuts against one side of the end portion thereof. The top block 1180 cooperates with the wedge-shaped inclined surfaces on both sides of the plug head 1150. The other end side in the length direction of the turning plate 118 is hinged to the limit clamping block 1161, and a torsion spring is provided at the hinge of the turning plate 118. Initially, the top block 1180 is located in the plugging groove 1160.

[0080] Through the collaborative cooperation of the plug-in component and the clamping component in the above embodiments, the rapid, stable and firm installation and fixation of the energy storage battery 111 in the charging slot are achieved. Specifically, the plug-in component consists of a plug-in slot 1160 provided on one side surface of the corresponding clamping block 115 of the blocking baffle 114. A magnetic attracting member 11600 is provided at the middle position of the bottom of the slot. One end of the clamping block 115 corresponding to the plug-in slot 1160 is provided with a plug connector 1150 that cooperates with the plug-in slot 1160. The wedge-shaped inclined surfaces on both sides of the plug connector 1150 and the connecting piece jointly achieve magnetic attraction cooperation with the magnetic attracting member 11600, ensuring the stable positioning of the clamping block 115. The clamping component consists of limit clamping blocks 1161 movably arranged at both sides of the opening end of the guiding slot 1130. Limiting grooves adapted to the limit clamping blocks 1161 are provided on both sides of one end of the clamping block 115 away from the plug connector 1150 to realize the limiting and fixing of the clamping block 115;

[0081] The following combines the Figure 5 figures (a) and (b) in the attached drawings to illustrate its specific implementation process. In specific implementation, when the energy storage battery 111 is installed in place, the plug connector 1150 at one end of the clamping block 115 is inserted into the plug-in slot 1160, and magnetic attraction connection is realized through the connecting piece and the magnetic attracting member 11600 at the middle position of the bottom of the slot, providing a stable magnetic attraction force for it. At the same time, the wedge-shaped inclined surfaces on both sides of the plug connector 1150 are in guiding cooperation with the top blocks 1180 in the cavity 117, that is, during the gradual insertion of the plug connector 1150, the plug connector 1150 can jack up the top blocks 1180 through the wedge-shaped inclined surfaces on both sides thereof, thereby promoting the movement of the top blocks 1180 under the guidance of the plug connector 1150 to push the flip plate 118 in the cavity 117 to flip, and then driving the limit clamping blocks 1161 to be inserted into the limiting grooves at the other end of the clamping block 115 through the flipping action of the flip plate 118 to complete the limiting and fixing of the clamping block 115, thereby promoting the stable installation of the energy storage battery 111 to ensure the installation and fixation of the energy storage battery 111 and prevent its displacement, thereby affecting the normal charging and discharging use of the energy storage battery 111. Compared with the prior art, the plug connector 1150 and the connecting piece through magnetic attraction cooperation provide a fast and stable connection method, reducing the time and labor intensity required for traditional mechanical fastening. Secondly, the design of the wedge-shaped inclined surface makes the cooperation between the plug connector 1150 and the plug-in slot 1160 closer, enhancing the firmness of the connection. And the automatic fastening process is realized through the linkage mechanism of the flip plate 118 and the limit clamping blocks 1161, improving the assembly efficiency and accuracy of the energy storage battery 111. And the design of the torsion spring enables the flip plate 118 to automatically reset, providing convenience for its continuous operation and also reducing the installation error of the energy storage battery 111 caused by improper operation.

[0082] Based on the above embodiments, it is further necessary to explain here. Please refer to Figure 2And Figure 6 , the battery swapping mechanism 100 includes a grasping component 101 and a moving component. The grasping component 101 moves downward in the battery swapping area 10 through the moving component to grasp and replace the corresponding energy storage battery 111. The grasping component 101 includes a supporting bracket 1010. Inside the supporting bracket 1010, a grasping plate 1012 is connected through a pneumatic push rod 1011. Multiple negative pressure suction cups 1013 are arranged on the upper part of the grasping plate 1012. The bottoms of the multiple negative pressure suction cups 1013 are connected to the grasping plate 1012 through lifting push rods, and a vacuum pump 1014 for evacuating the negative pressure suction cups 1013 is installed at the bottom of the grasping plate 1012.

[0083] It should be noted that the battery swapping mechanism 100 disclosed in this embodiment realizes the automatic grasping and replacement of the energy storage battery 111 through the integrated grasping component 101 and moving component. The grasping component 101 is composed of a supporting bracket 1010 and a pneumatic push rod 1011. The pneumatic push rod 1011 is connected to the grasping plate 1012, and multiple negative pressure suction cups 1013 are arranged on the upper part of the grasping plate 1012. These suction cups are connected to the grasping plate 1012 through lifting push rods and are used to adsorb and release the energy storage battery 111. The vacuum pump 1014 at the bottom of the negative pressure suction cup 1013 is responsible for evacuating the air to ensure that the suction cup can firmly adsorb the energy storage battery 111 and achieve stable grasping. Specifically, during the battery swapping process, the moving component moves the grasping component 101 to one side of the energy storage battery 111 to be replaced, so that the supporting bracket 1010 is aligned below the energy storage battery 111 to be replaced. At the same time, the pneumatic push rod 1011 drives the grasping plate 1012 in the supporting bracket 1010 to move to the area between the clamping blocks 115 on both sides directly below the energy storage battery 111. At this time, the lifting push rod will push the negative pressure suction cup 1013 to rise to contact and adsorb the bottom of the energy storage battery 111. At the same time, the vacuum pump 1014 starts to work and generates a vacuum negative pressure on the negative pressure suction cup 1013, so that the negative pressure suction cup 1013 firmly adsorbs the energy storage battery 111. After it is firmly adsorbed, the pneumatic push rod 1011 drives the grasping plate 1012 to retract into the supporting bracket 1010 and moves it to the battery swapping door 12 through the moving component, thereby realizing the replacement and charging of the energy storage battery 111. Then, through the above repeated process, the rapid replacement of the battery is completed.

[0084] It should be added that in this embodiment, the moving component, as the mechanism for driving the grasping component 101 to move, is itself a prior art. Therefore, no specific limitations are imposed on it in this solution. Only a preferred example is described here. It is preferably a multi-joint robotic arm 102, which is installed in the battery swapping area 10. And its action execution end (free end) is connected to the bearing bracket 1010 of the grasping component 101 through a movable joint connecting piece. In this way, the multi-joint robotic arm 102 can operate independently in the X, Y, and Z axis directions inside the packaging shell 1, so as to achieve precise position and attitude control, thereby facilitating its driving of the grasping component 101 to perform the grasping and replacement work on the energy storage battery 111.
