Technical Field

[0001] The present invention relates to the field of mobile energy storage technology, and in particular to mobile electric energy storage equipment for new energy vehicles. Background Art

[0002] As an efficient energy storage and dispatching solution, mobile electric energy storage containers are mainly used to support the power supply during the charging process of electric vehicles, especially when the power grid cannot stably provide sufficient power. This equipment can store electric energy during the low load period of the power grid and release it during the peak charging period, balancing the load of the power grid, improving the charging speed, and ensuring that electric vehicles can obtain convenient power support in different scenarios. Structurally, mobile electric energy storage containers usually use standard container shells, which are durable and corrosion-resistant. It contains a large-capacity lithium battery pack that is responsible for storing electric energy and converting direct current into alternating current suitable for electric vehicles through an inverter. In order to ensure the safety and stability of the battery, the container is equipped with a battery management system (BMS) to monitor the battery status in real time, and optimize power dispatch through an energy management system (EMS). In addition, the cooling system ensures that the battery maintains normal temperature during the charging and discharging process and prolongs its service life. The intelligent control system provides remote monitoring and management to ensure efficient and safe operation of the system; For example, the mobile electric energy storage device for new energy vehicles disclosed in the authorization announcement number CN116278883B includes a traction device, a placement platform is arranged on the surface of the traction device, a traction bracket and a power supply body are arranged at the end of the traction device, a mobile platform that can slide laterally is arranged on the surface of the placement platform, and a platform support for supporting the mobile platform is arranged inside the mobile platform; by arranging a mobile platform that can slide laterally on the surface of the placement platform, it can achieve lateral movement in the left and right directions, so that the power supply body can be moved to both sides of the traction device in a lateral movement manner to form a power supply platform in an independent direction. The above technical solution is the same as the prior art, and the original intention of the design is mainly focused on The storage, management and dispatch of electric energy, its main function is to serve as a temporary power supply point to provide power support for electric vehicle charging. However, during use, it does not provide a shelter for the vehicles to be charged, operators, and users to temporarily avoid the external environment (such as rain and snow). The electric vehicle charging process involves high-power flow of electricity. If the weather is bad, especially rainy and snowy weather, batteries, charging equipment, etc. are exposed, which will increase the risk of electrical safety problems such as leakage and short circuit. At the same time, during the operation, operators may be exposed to dangerous environments such as electric shock without appropriate shelter facilities. For users, there is no shelter, and users also need to wait in a cold or humid environment, affecting the user experience. Summary of the invention

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. 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.

[0019] At the same time, two side wing plates 7 are symmetrically slidably installed on the top of the electric energy storage container 2, and the sliding direction of the side wing plates 7 is perpendicular to the length direction of the ceiling 6. A gear-type double-side belt opposing traction module 9 for driving the two side wing plates 7 to move toward each other is installed on one side of the top of the electric energy storage container 2, and a rotating drive module 10 for driving the gear-type double-side belt opposing traction module 9 to work is installed on one side of the bottom of the ceiling 6; and two support plates 8 are fixed at the corner position of the top of the electric energy storage container 2 on one side of the gear-type double-side belt opposing traction module 9. A wheel axle transmission structure 11 for receiving the rotational force from the gear-type double-side belt counter-traction module 9 is provided at the top end of the support plate 8, and a lifting and adjustable side stop module 12 is installed at the rotating end of the wheel axle transmission structure 11. A toothed trunk cover 13 is slidably installed on one side of the bottom end of the ceiling 6. The wheel axle transmission structure 11 is used to drive the toothed trunk cover 13 to slide along the length direction of the ceiling 6. A control panel 5 is installed on the outer wall of the electric energy storage container 2 on one side of the charging interactive terminal 4, and the output end of the control panel 5 is electrically connected to the input end of the rotation drive module 10.

[0020] In some embodiments, Figure 7 , Figure 8 and Fig. 9 As shown, the gear-type double-side belt opposite traction module 9 includes a square longitudinal beam 9011 fixed to one side of the top of the electric energy storage container 2, two driven shafts 901 rotatably mounted on the outer wall of one side of the square longitudinal beam 9011 through a bearing seat, two driving shafts 902 rotatably mounted on the outer wall of the square longitudinal beam 9011 between the two driven shafts 901 through a bearing seat, and a driven pulley 903 and a driving pulley 904 fixed on the top of the driven shaft 901 and the driving shaft 902. A multi-V belt 905 is set between 904, a pair of gear transmission structure 1 907 is set between the top ends of the two driving shafts 902, and a pair of gear transmission structure 2 908 is set at the top end of the driven shaft 901 for driving the wheel axle transmission structure 11 to work, and a traction plate 906 is slidably installed on the outer wall of one side of the square-mouth longitudinal beam 9011, an inner wall of one side of the multi-V belt 905 is fixedly connected to the outer wall of one side of the traction plate 906, and the outer wall of the other side of the traction plate 906 is fixedly connected to the outer wall of one side of the side wing plate 7.

[0021] Specifically, the rotation drive module 10 is a servo motor installed on one side of the bottom end of the ceiling 6. The output shaft of the servo motor is fixedly connected to the top of one of the driving shafts 902 through a coupling. The rotation drive module 10 adopts a servo motor, which provides rotational power and converts the rotational motion into mechanical action of each execution module, that is, driving the gear-type double-side belt opposite traction module 9, so that it can accurately pull and unfold the side wing panel 7, and at the same time transmit part of the power to the wheel axle transmission structure 11. In this process, the servo motor has the synchronization and stability of movement, thereby ensuring that the side wing panel 7, the lifting and adjustable side block module 12 and the toothed trunk cover 13 can be smoothly and accurately unfolded.

[0022] It should be noted that, through the above arrangement, the servo motor can drive another driving shaft 902 to rotate through the gear transmission structure 907, and the input end of the servo motor is electrically connected to the output end of the control panel 5. When the rotation drive module 10 drives the gear-type double-sided belt counter-traction module 9 to work, the rotation drive module 10 drives the two driving shafts 902 to rotate synchronously and in the opposite direction through the gear transmission structure 907. Then the driving pulley 904 uses the driving pulley 904 and the multi-V belt 905 to drive the driven pulley 903 and the driven shaft 901 to rotate, and the multi-V belt During the rotational movement, 905 will drive the traction plate 906 to slide. Since the traction plate 906 is fixedly connected to one of the side wing plates 7, the traction plate 906 will drive the side wing plate 7 to gradually move out from the ceiling 6 until the traction plate 906 moves to the end position of the square-mouth longitudinal beam 9011. At this time, the side wing plate 7 also moves to the extreme position. The combination of gears and double-side belts can ensure that the two side wing plates 7 are unfolded simultaneously and in a balanced manner, which can avoid the lateral tilt or imbalance problems that may occur in the traditional unilateral traction method and improve the stability and accuracy of the unfolding.

[0023] After the side wing panels 7 are moved, they provide comprehensive protection for the vehicle to be charged, the staff and other operators. At the same time, they can be quickly retracted when not needed to prevent the side wing panels 7 from being deployed and affecting the width of the vehicle body.

[0024] A guide rail 201 is fixed to the top of the electric energy storage container 2, a slider for slidingly cooperating with the guide rail 201 is installed on one side of the bottom end of the side wing plate 7, two parallel linear guide rails of equal length are installed on one side outer wall of the square longitudinal beam 9011, and a sliding sleeve for slidingly cooperating with the linear guide rail is fixed on one side outer wall of the traction plate 906. During the sliding process of the two side wing plates 7, the bottom ends of the two side wing plates 7 will share a guide rail 201 through the slider, and the guide rail 201 and the slider are used to reduce the sliding offset and vibration of the side wing plates 7.

[0025] In some other embodiments, the axle transmission structure 11 is responsible for synchronously transmitting the power provided by the rotation drive module 10 to various components to ensure their normal operation and reduce failures caused by power transmission problems; Fig.10 and Fig.11 As shown, the wheel-axle transmission structure 11 includes a secondary transmission shaft 1101 rotatably installed on one side of the top of the support plate 8, a gear shaft 1102 rotatably installed on the other side of the top of the support plate 8, and a pulley transmission structure 1103 for maintaining power connection between the secondary transmission shaft 1101 and the gear shaft 1102. The secondary transmission shaft 1101 and the driven shaft 901 are dynamically engaged through the gear transmission structure 2 908. The bottom end of the gear shaft 1102 is fixedly connected to the top of the lifting adjustable side stop module 12. A tensioning wheel 1106 for pressing against the pulley transmission structure 1103 is provided on one side of the top of the support plate 8. The tensioning wheel 1106 puts the pulley transmission structure 1103 in a tensioned state to maintain power connection between the gear shaft 1102 and the secondary transmission shaft 1101. A tail shaft 1104 is rotatably installed on the other side of the top of the support plate 8. A third-stage gear 1105 for meshing with the gear shaft 1102 is fixed on the top of the tail shaft 1104.

[0026] When the gear-type double-sided belt counter-traction module 9 transmits the rotational power to the wheel shaft transmission structure 11, the driven shaft 901 drives the secondary transmission shaft 1101 in the wheel shaft transmission structure 11 to rotate through the gear transmission structure 908. After the transmission of the gear transmission structure 908, the secondary transmission shaft 1101 can rotate synchronously with the driven shaft 901 in the opposite direction. Then the secondary transmission shaft 1101 drives the gear shaft 1102 to rotate through the pulley transmission structure 1103, and the gear shaft 1102 is used to rotate the lifting adjustable side block module 12. , so that the lifting and adjustable side baffle module 12 is gradually deployed from the side wall of the electric energy storage container 2, until the extension surface of the lifting and adjustable side baffle module 12 forms an angle with the extension surface of the side wall of the electric energy storage container 2, so as to form a shielding area suitable for the vehicles to be charged, staff and users to stay by using the lifting and adjustable side baffle module 12. At this time, the side wing panels 7 and the lifting and adjustable side baffle module 12 respectively provide top protection and side protection, thereby providing effective protection to avoid the influence of bad weather on the equipment and personnel inside and outside the container.

[0027] The gear transmission structure 908 includes a secondary gear 9082 fixed on the top of the secondary transmission shaft 1101 and a primary gear 9081 fixed on the top of the driven shaft 901. The primary gear 9081 and the secondary gear 9082 are meshed with each other. The primary gear 9081 and the secondary gear 9082 ensure that there is always power connection between the secondary transmission shaft 1101 and the driven shaft 901, which helps the wheel axle transmission structure 11, the lifting adjustable side block module 12, the gear-type double-side belt opposite traction module 9, and the side wing plate 7 to share the rotational power from the rotating drive module 10.

[0028] The lifting adjustable side block module 12 includes an outer frame plate 1201 fixed to the bottom end of the gear shaft 1102, a screw rod 1202 rotatably mounted on the outer wall of one side of the outer frame plate 1201, and a nut pair 1203 installed at a threaded portion of one end of the surface of the screw rod 1202. A baffle plate 1204 is fixed to the outer wall of one side of the nut pair 1203. The outer wall of the other side of the nut pair 1203 is slidably matched with the outer wall of one side of the outer frame plate 1201. The bottom end of the screw rod 1202 passes through the outside of the outer frame plate 1201 and is equipped with a hand wheel. After 12 is unfolded, the staff can manually screw the screw rod 1202, and use the screw rod 1202 to drive the nut pair 1203 and the baffle 1204 to move downward, so that the outer frame plate 1201 and the baffle 1204 are misaligned, and then the shielding surface composed of the outer frame plate 1201 and the baffle 1204 is further extended, so that the size and shielding effect of the shielding area can be adjusted according to actual needs. Regardless of strong winds, strong sunlight or rain, the lifting and adjustable side baffle module 12 can provide effective protection to adapt to different environments and usage scenarios.

[0029] In some other embodiments, the toothed trunk cover 13 includes a C-shaped tail cover 1301 slidably mounted on one side of the bottom end of the ceiling 6 and a toothed portion 1302 provided on the outer wall of one side of the C-shaped tail cover 1301, and the C-shaped tail cover 1301 is meshed with the three-stage gear 1105 through the toothed portion 1302, such as Fig.12 and Fig.13 shown.

[0030] In addition, the outer frame plate 1201 is composed of a U-shaped frame and a back plate. The top of the U-shaped frame is fixedly connected to the bottom end of the gear shaft 1102, and the back plate is fixed on one side outer wall of the U-shaped frame.

[0031] It can be understood that the gear shaft 1102 drives the tail shaft 1104 to rotate through the three-stage gear 1105, and the three-stage gear 1105 is meshed with the tooth groove portion 1302 on the outer wall of the C-shaped tail cover 1301, and the rotational motion of the tail shaft 1104 will be converted into linear motion of the C-shaped tail cover 1301 through the three-stage gear 1105 and the tooth groove portion 1302, that is, the C-shaped tail cover 1301 will also be gradually moved out from the ceiling 6 during the unfolding process of the lifting adjustable side stop module 12 and the side wing panel 7. The C-shaped tail cover 1301 is at the rear of the electric energy storage container 2, and is used to protect the equipment and reduce the impact of the external environment.

[0032] The side wing panels 7, the lifting adjustable side baffle module 12 and the toothed trunk cover 13 are unfolded, and the movements of each part are synchronously and smoothly unfolded within a predetermined time, and a closed sheltering environment is formed.

[0033] When using the mobile electric energy storage device for new energy vehicles of the present invention, the flatbed tractor 1 is first connected to the driving vehicle as the infrastructure for moving the electric energy storage container 2, so that the electric energy storage container 2 can be carried to enter the parking area where the vehicle to be charged is located. At this time, in order for the flatbed tractor 1 and the electric energy storage container 2 to enter the charging area of ​​the charging vehicle, the flatbed tractor 1 and the electric energy storage container 2 drive the vehicle to move to a designated position to ensure that the electric energy storage container 2 stays parallel to one side of the charging vehicle, thereby providing a stable foundation for subsequent charging operations. The staff also needs to ensure that the battery pack in the electric energy storage container 2 is fully charged, and all the connection lines and inverter equipment of the electric energy storage system of the electric energy storage container 2 are working normally. Once it is confirmed that the electric energy storage container 2 is in a normal state, the staff will activate the electric energy storage container 2 through the control panel to provide the required power for the upcoming charging process; After the flatbed tractor 1 and the driving vehicle park the electric energy storage container 2 in the charging area, the staff needs to connect the charging gun 3. During this process, the staff operates the charging interactive terminal 4 to confirm that the electric vehicle to be charged is compatible with the terminal, and sets the appropriate charging mode according to the vehicle model. The charging interactive terminal 4 not only provides the display of charging information, but also can intelligently control the operation of the charging gun 3, such as adjusting the charging power, monitoring the current and voltage, etc. The staff safely connects the charging gun 3 to the charging port of the electric vehicle, and starts charging after confirming that the connection is correct through the charging interactive terminal 4; Before charging and during charging, the staff turns on the rotary drive module 10 through the control panel 5 to work, and uses the rotary drive module 10 to drive the gear-type double-side belt traction module 9 to work. The rotary drive module 10 can achieve symmetry and uniform traction force distribution, that is, the rotary drive module 10 is combined with the double-side belt through gears, and can simultaneously pull the side wing plates 7 on both sides under the command of the control panel 5. At this time, driven by the rotary drive module 10 and the gear-type double-side belt traction module 9, the side wing plates 7 will extend along the preset track until they are moved out from the ceiling 6. The opposite synchronous traction is arranged to ensure that the deployment of the two side wing panels is synchronous and balanced. When the gear-type double-side belt opposite traction module 9 completes the initial deployment of the roof 6, the wheel axle transmission structure 11 also receives the rotational power from the gear-type double-side belt opposite traction module 9 and acts synchronously, that is, the wheel axle transmission structure 11 transmits the power to the lifting and adjustable side block module 12 and the toothed trunk cover 13 through mechanical linkage such as gears and synchronous belts. At this time, the lifting and adjustable side block module 12 will be deployed from the side wall of the flatbed tractor 1 to form a shielding protection for the charging vehicle, staff and users; It should be noted that in this process, the height or angle of the lifting and adjustable side baffle module 12 is allowed to be adjusted as needed to meet different shielding requirements. The toothed trunk cover 13 moves backward under the drive of the wheel axle transmission structure 11 until it is fully unfolded.
