Detailed Implementation

[0035] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0036] This utility model discloses an energy storage charging device, such as Figure 1-13 As shown, the device includes a housing 7, an outer cover 1 on the top surface of the housing 7, a battery mounting plate 9 on the bottom surface of the housing 7, and a battery pack 8 inside the battery mounting plate 9. The housing 7, the outer cover 1, and the battery mounting plate 9 are all made of high-strength, corrosion-resistant, and well-insulated metal materials. Their surfaces are specially treated to provide excellent protection and effectively resist the erosion of harsh environmental factors.

[0037] Battery pack 8 adopts a modular design, consisting of multiple lithium iron phosphate battery cells, which facilitates capacity expansion or replacement according to actual needs. At the same time, it selects high energy density and long cycle life lithium iron phosphate batteries as the core energy storage unit. Its capacity is sufficient to meet the charging needs of common electric vehicles, especially in roadside assistance scenarios, where it can provide crucial power replenishment for electric vehicles that have run out of power.

[0038] Storage boxes 102 are fixedly installed on both the left and right sides of the outer surface of the housing 7. Inside the storage box 102, there are two movable frames 1021. The top surface of the movable frame 1021 is threaded with a first threaded rod 1023. The bottom end of the first threaded rod 1023 is rotatably connected to a ball seat 1024. A slide rod 1022 is slidably connected to one side of the top surface of the movable frame 1021, and the bottom end of the slide rod 1022 is fixedly connected to the ball seat 1024. The top end of the first threaded rod 1023 is provided with a handle. When the user holds and rotates the handle, the first threaded rod 1023 can be rotated. When the first threaded rod 1023 rotates, it will push the ball seat 1024 to rise and fall. At the same time, the slide rod 1022 will move with the rise and fall of the ball seat 1024. The slide rod 1022 can guide the rise and fall of the ball seat 1024.

[0039] The ball seat 1024 has a ball head 1026 inside, which can rotate inside the ball seat 1024. Both sides of the outer surface of the ball seat 1024 are threaded with fastening bolts 1025. The user can manually rotate the fastening bolts 1025 so that the two fastening bolts 1025 abut against the ball head 1026, thus fixing the ball head 1026.

[0040] An anti-slip plate 1027 is fixedly installed on the outer surface of the ball head 1026. Two ground spikes 1028 are provided on the top surface of the anti-slip plate 1027, and multiple anti-slip teeth are provided on the bottom of the anti-slip plate 1027. The anti-slip teeth can effectively improve the friction between the anti-slip plate 1027 and the ground. Users can also observe the ground environment. If the ground environment permits, the ground spikes 1028 can be inserted into the ground to improve stability. The storage box 102 is equipped with a drive component inside.

[0041] Furthermore, by setting up four movable frames 1021, the user can individually adjust the height and angle of the four anti-slip plates 1027 to adapt to rough ground. The user rotates the four first threaded rods 1023 in sequence, which pushes the four ball seats 1024 and the four anti-slip plates 1027 to descend until all four anti-slip plates 1027 are in contact with the ground and the ground nails 1028 are inserted into the ground. By rotating the ball head 1026 inside the ball seat 1024, the angle of the anti-slip plate 1027 can be adjusted, which facilitates effective support for the charging device on rough ground.

[0042] The drive assembly includes a second threaded rod 1042 rotatably connected inside the storage box 102. A drive block 1043 is slidably connected inside the storage box 102, and the outer surface of the second threaded rod 1042 is threadedly connected to the drive block 1043. Drive arms 1044 are hinged to both sides of the drive block 1043. Movable plates 1045 are slidably connected to both sides of the inside of the storage box 102. The second threaded rod 1042 is located between the two movable plates 1045.

[0043] Furthermore, the ends of the two drive arms 1044 away from the drive block 1043 are respectively hinged to the two movable plates 1045, and the two movable plates 1045 are respectively fixedly connected to the two movable frames 1021. The outer top surface of the storage box 102 is rotatably connected to the handle 1041, and the handle 1041 is fixedly connected to the second threaded rod 1042. The bottom end of the handle 1041 extends into the storage box 102 and is fixedly connected to the top end of the second threaded rod 1042.

[0044] When the user holds and rotates the handle 1041, the second threaded rod 1042 will rotate. The rotation of the second threaded rod 1042 will cause the drive block 1043 to rise and fall. In turn, the two drive arms 1044 will push the two movable plates 1045 to move in opposite directions. When the drive block 1043 rises, the two drive arms 1044 will drive the two movable plates 1045 to move closer to each other. When the drive block 1043 falls, the two drive arms 1044 will push the two movable plates 1045 to move away from each other.

[0045] This allows the mobile rack 1021 to be stored or unfolded, thereby reducing the space occupied by the charging equipment during vehicle operation.

[0046] A storage rack 103 is fixedly installed on the front of the outer surface of the housing 7. A winding roller 1031 is rotatably connected inside the storage rack 103. A handle 1033 is rotatably connected to one side of the outer surface of the storage rack 103. One end of the handle 1033 passes through the storage rack 103 and is fixedly connected to the winding roller 1031. When the user manually rotates the handle 1033, it will drive the winding roller 1031 to rotate. Two telescopic tubes 1032 are fixedly installed on the outer surface of the winding roller 1031.

[0047] The outer surface of the storage rack 103 has a movable groove 1037 on one side of the handle 1033. A guide rod 1038 is fixedly installed inside the movable groove 1037. A first spring 1036 is fixedly installed on the inner top surface of the movable groove 1037. The first spring 1036 is sleeved on the outer end of the guide rod 1038. A limit rod 1034 is slidably connected to the outer surface of the guide rod 1038. The bottom end of the first spring 1036 is fixedly connected to the limit rod 1034. The limit rod 1034 can move along the guide rod 1038.

[0048] When the limiting rod 1034 rises along the guide rod 1038, it will compress the first spring 1036. The side of the handle 1033 is provided with multiple limiting grooves 1035. When the limiting rod 1034 descends due to the elasticity of the first spring 1036, it will be inserted into the limiting groove 1035. Thus, the limiting rod 1034 will prevent the handle 1033 from continuing to rotate, thereby limiting the winding roller 1031.

[0049] The top surfaces of the two telescopic tubes 1032 are slidably connected to connecting rods 1053. The top ends of the two connecting rods 1053 are located outside the two telescopic tubes 1032 and are fixedly connected to a fixing rod 1039. The bottom ends of the two connecting rods 1053 are located inside the two telescopic tubes 1032 and are fixedly installed with connecting plates 1051. When the two connecting rods 1053 are raised or lowered, they will drive the connecting plates 1051 to be raised or lowered.

[0050] The inner top surfaces of the two telescopic tubes 1032 are each fixedly installed with a second spring 1052, and the two second springs 1052 are respectively sleeved on the outer ends of the two connecting rods 1053 and respectively fixedly connected to the two connecting plates 1051.

[0051] The user pulls the fixing rod 1039, causing the two connecting rods 1053 to drive the two connecting plates 1051 to compress the two second springs 1052. Then, the DC charging gun 701 is passed between the fixing rod 1039 and the take-up roller 1031, and the fixing rod 1039 is released. The compressed second springs 1052 will then drive the fixing rod 1039 to reset, so that the fixing rod 1039 and the take-up roller 1031 clamp the connecting wire of the DC charging gun 701. Then, the handle 1033 is rotated to drive the take-up roller 1031 to rotate, so that the connecting wire of the DC charging gun 701 can be wound up for safekeeping during vehicle operation.

[0052] An air outlet 703 is provided on the rear side of the outer surface of the housing 7, and an air inlet 702 is provided on the front side of the outer surface of the housing 7, so as to dissipate the heat generated during the operation of the equipment in a timely manner and ensure the stable operation of the equipment.

[0053] The overall equipment adopts a compact and lightweight structural design. While ensuring the integrity and stability of the functions of each internal module, it minimizes the size and weight of the equipment, making it easy to transport and carry. Whether transported to remote areas by rescue vehicles or operated in confined spaces, it can easily cope with the challenges.

[0054] Each module is electrically connected via ribbon cables or wires, with a compact and reasonable layout that facilitates installation, maintenance, and repair.

[0055] An AC charging socket 705 is provided on the rear side of the outer surface of the housing 7. The AC charging socket 705 is used to connect to the mains power for charging.

The touch screen 708 is used to clearly display the device status, charging information, fault prompts and other content.

[0056] Multiple indicator lights 707 are fixedly installed on the front of the outer surface of the housing 7. The multiple indicator lights 707 are used to intuitively indicate the power status, charging status, communication status, etc. of the device.

[0057] The bottom surface of the battery mounting plate 9 is equipped with four omnidirectional self-locking wheels 903. The omnidirectional self-locking wheels 903 facilitate flexible movement at the road rescue scene and can quickly reach the location of the disabled electric vehicle. The front of the outer surface of the housing 7 is equipped with a DC charging gun 701. By inserting the DC charging gun 701 into the charging port of the electric vehicle, the electric vehicle can be charged.

[0058] A first cooling fan 901 is fixedly installed on the left side inside the battery mounting plate 9, and a second cooling fan 902 is fixedly installed on the right side inside the mounting plate. When the first cooling fan 901 and the second cooling fan 902 are running, they will cause air to circulate, which can dissipate the heat generated during the operation of the equipment in a timely manner, ensuring the stable operation of the equipment. The top surface of the outer shell cover 1 is provided with two handles 101. The handles 101 are foldable and easy to operate, so that users can hold the handles 101 to carry the charging equipment, making it easier for operators to operate during movement and improving the mobility of the equipment in road rescue scenarios.

The housing 7 has a DC / DC charging module 5, an AC / DC charging module 6, and a control system mounting plate 2.

[0060] A DC / DC switching power supply 201 is provided on one side of the top surface of the control system mounting plate 2, and an AC / DC switching power supply 202 is fixedly installed on one side of the top surface of the control system mounting plate 2. A battery management system 203 is provided on one side of the top surface of the control system mounting plate 2. The battery management system 203 can monitor key parameters such as battery voltage, current and temperature in real time and accurately. The battery management system 203 has an automatic voltage balancing function, which can ensure the voltage balance of each individual battery in the battery pack 8, effectively avoid overcharging and over-discharging, and thus significantly extend the battery life.

[0061] When abnormal fluctuations occur in battery temperature, the battery management system 203 can quickly activate the corresponding heat dissipation or heating mechanism to keep the battery in the best working state and ensure the stable operation of the energy storage module in various complex environments.

[0062] An electronic lock controller 204 is fixedly installed on one side of the top surface of the control system mounting plate 2. A main controller 205 is fixedly installed on one side of the top surface of the control system mounting plate 2. The main controller 205 can be equipped with a 4G / 5G wireless communication module, a WIFI communication module, or a GPS positioning module.

[0063] The communication module can connect to the charging pile's operation or maintenance platform. The platform can preset charging time periods based on the local power grid's peak, valley, and flat rates, making full use of off-peak electricity prices to reduce charging costs. Furthermore, the equipment can interact with the rescue command center or the user's mobile APP in real time during road rescue operations.

[0064] Once connected to a malfunctioning electric vehicle, the device automatically uploads information such as the vehicle's battery status and charging progress to the rescue command center, allowing rescue personnel to remotely monitor the situation and make informed decisions. Simultaneously, users can also view the charging status and estimated completion time in real time via a mobile app.

[0065] With a built-in high-precision GPS positioning module, the device can locate its position in real time and synchronize the location information to the rescue command center. This not only helps rescuers find the device quickly and improves rescue efficiency, but also enables rapid tracking and retrieval when the device is lost or stolen.

[0066] The main controller 205 is equipped with voltage and current detection interfaces. Once an abnormal fluctuation in the grid voltage is detected that exceeds the allowable range, the intelligent charging control circuit will immediately and automatically stop the charging operation, providing comprehensive protection for the energy storage battery and charging equipment and preventing equipment damage caused by grid problems.

[0067] Employing a high-performance bidirectional DC / DC converter chip, it can stably and efficiently convert the DC power output from the energy storage battery into charging voltage and current levels suitable for different models of electric vehicles, fully meeting the charging needs of various electric vehicles.

[0068] The AC charging socket 705 is connected to the AC / DC charging module 6. The AC / DC charging module 6 includes a high-performance rectifier bridge that converts AC power into DC power. After passing through a first-stage filter circuit to remove high-frequency noise, the power is then connected to an intelligent charging control chip. The intelligent charging control chip precisely controls the charging current and voltage according to the instructions sent by the microcontroller, so as to charge the battery pack 8 safely and efficiently.

[0069] The battery management system 203 detects and receives all the states of the AC / DC charging module 6 and communicates with the main controller 205. The main controller 205 controls the voltage and current output of the AC / DC charging module 6 based on the information fed back by the battery management system 203.

[0070] Throughout the charging process, the battery management system 203 monitors the input voltage, current, and the status of the energy storage battery pack 8 in real time, and feeds the data back to the main controller 205 for real-time adjustment and control.

[0071] The DC power output from the battery pack 8 is connected to the DC / DC charging module 5. The DC / DC charging module 5 adjusts the voltage and current to appropriate values ​​through its internal PWM control circuit according to the parameters of the electric vehicle battery, and then charges the electric vehicle through the DC charging gun 701.

[0072] The DC / DC charging module 5 is controlled by the main controller 205, which is connected to the battery management system 203 via the DC charging gun 701.

[0073] During the charging process, the main controller 205 receives the vehicle's battery information in real time and collects the charging voltage and current. The main controller 205 integrates all the data information and adjusts the output voltage and current of the DC / DC charging module 5 in real time to accurately control the charging process and ensure that the charging process is safe, fast and efficient.

[0074] Meanwhile, the DC / DC charging module 5 also has multiple protection functions such as overvoltage protection, overcurrent protection, and short circuit protection. Once an abnormal situation is detected, the output will be cut off immediately to protect the electric vehicle battery and charging equipment.

[0075] The working principle of this utility model is as follows: The user holds and rotates the handle 1041 to rotate the second threaded rod 1042, causing the drive block 1043 to descend, and causing the two drive arms 1044 to push the two movable plates 1045 away from each other, so as to unfold the movable frame 1021. By rotating the ball head 1026 inside the ball seat 1024, the angle of the anti-slip plate 1027 can be adjusted. After the adjustment is completed, the fastening bolt 1025 can be rotated to fix the ball head 1026 against it. Then, the four first threaded rods 1023 are rotated in sequence to push the ball seat 1024 and the anti-slip plate 1027 to descend until the anti-slip plate 1027 contacts the ground.

[0076] If ground conditions permit, ground stakes 1028 can be inserted into the ground to provide effective support for the charging equipment on rough terrain, so as to prevent the charging equipment from tipping over and being damaged due to the rough terrain.

[0077] The user pushes the limit rod 1034 up, causing it to compress the first spring 1036, and rotates the handle 1033 to drive the take-up roller 1031 to rotate, thereby releasing the connecting wire of the DC charging gun 701 wound on the outer surface of the take-up roller 1031 and the fixing rod 1039.
