Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a charging module and its installation structure. Background Technology

[0002] With the rapid development of new energy technologies and the widespread application of energy storage, electric vehicles, and other fields, the demand for large-scale deployment and efficient operation and maintenance of charging equipment is becoming increasingly prominent. As the core functional unit of charging equipment, the installation efficiency, stability, and ease of maintenance of the charging module directly affect the construction cost and operational reliability of the entire charging system. In scenarios such as large charging stations and energy storage power stations, dozens or even hundreds of charging modules are typically required to achieve high-power output and redundancy backup. Therefore, there is an urgent need for an installation solution that can meet the requirements for rapid deployment of multiple modules.

[0003] Currently, charging module installation mostly adopts traditional methods such as bolt fixing and bracket splicing. These methods have many limitations: First, the installation process relies on manual alignment and tightening of each module, which is cumbersome and time-consuming. Especially in multi-module stacking scenarios, differences in manual positioning accuracy can easily lead to module installation misalignment, affecting the reliability of subsequent electrical connections. Second, traditional structures lack dedicated guiding and limiting mechanisms. After the module is placed in the housing, it is prone to positional displacement due to shaking or vibration during handling, increasing the risk of poor contact at the docking terminals, which can lead to malfunctions such as overheating and power outages. Third, during maintenance, disassembling the module requires loosening and removing the fasteners one by one, resulting in low work efficiency and extended equipment downtime.

[0004] Meanwhile, existing installation structures have significant shortcomings in terms of protection and automation. Some structures omit side protection components to simplify the installation process, making the modules susceptible to damage from lateral impacts during transportation and operation. Structures with protective features often require additional manual operation to open and close the protective components, contradicting the need for rapid installation. Furthermore, the application of automation technology in charging module installation is limited; most installations still rely on manual handling, positioning, and securing of the modules, increasing labor costs and making it difficult to guarantee consistent installation quality.

[0005] Therefore, a charging module and installation structure need to be designed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a charging module and installation structure. This invention enables rapid import of multiple modules, automatic alignment and fixation, and combines good protection performance with versatility. It has significant practical implications for reducing installation and maintenance costs and improving system stability, and also conforms to the trend of large-scale and intelligent development of charging equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An installation structure for a charging module includes a housing, with multiple fixing plates fixedly connected to the inner walls of both the front and rear sides of the housing, and the multiple fixing plates being fixedly connected to a placement platform. The front side of the housing is provided with a placement inlet, and a cover plate is rotatably connected to the front side of the placement inlet via a hinge. The lowering module includes four rotating shafts, four drive rollers, a servo motor, and multiple shrinking assemblies. The two ends of the four rotating shafts are rotatably connected to the inner walls of the front and rear sides of the housing. The four drive rollers are fixedly connected to the corresponding rotating shafts. Every two cooperating drive rollers are connected by a conveyor belt. The multiple shrinking assemblies are installed on the left and right sides of the corresponding conveyor belts, with two shrinking assemblies forming a group. A gearbox is provided on the rear inner wall of the housing. The rotating shaft on the right side is fixedly connected to the output shaft of the gearbox, and the rotating shaft on the left side is connected to the input shaft of the gearbox by a first transmission assembly. The servo motor is installed on the front side of the housing and is fixedly connected to the rotating shaft on the left side.

[0008] Preferably, the shrink assembly includes a shrink box, a shrink block is slidably connected inside the shrink box, the shrink block is elastically connected to the inner wall of the shrink box near the conveyor belt by a first spring, and a side plate is fixedly connected to the shrink block.

[0009] Preferably, the device further includes a side protection assembly, which includes two side guards located on the left and right sides of the placement platform, respectively. Multiple first slide rails are fixedly connected to the inner bottom of the housing, and sliders are slidably connected to each of the first slide rails. A connecting block is fixedly connected to each slider, and each connecting block is fixedly connected to the lower end of the corresponding side guard. Racks are fixedly connected to the front sides of the two sliders located on the rear side. Rotary rods are rotatably connected to the inner walls of the left and right sides of the housing, and two gears are fixedly connected to the rotary rods, meshing with corresponding racks.

[0010] Preferably, the placement platform has two rectangular openings on both the left and right sides, the upper ends of the two side guards are inclined, the two side guards have vertical openings equal to the rectangular openings, and the lower ends of the multiple shrink blocks are all curved.

[0011] Preferably, a bearing seat is fixedly connected to the left side of the housing, and a short rod is installed on the bearing seat. The short rod is connected to the rotating shaft located on the left side through a second transmission assembly. A transmission rod is rotatably connected to the right side of the housing. The transmission rod is connected to the rotating rod through a connecting assembly. Both the short rod and the transmission rod are provided with meshing bevel gears. Two pressure sensors are installed at the upper end of the placement platform.

[0012] Preferably, the connecting assembly includes a rectangular groove on the left side of the rotating rod, a movable groove on the right side of the transmission rod, an electromagnet installed on the left inner wall of the movable groove, a rectangular block slidably connected in the movable groove, and the rectangular block and the adjacent side of the electromagnet are elastically connected by a second spring. In the initial state, the rectangular block is located between the rotating rod and the transmission rod.

[0013] Preferably, cylinders are installed on the inner walls of both the front and rear sides of the housing, and second slide rails are fixedly connected to the upper ends of the plurality of fixed plates. Side alignment plates are slidably connected to the plurality of second slide rails. A connecting plate is fixedly connected to the adjacent sides of every two cooperating side alignment plates, and the telescopic ends of the two cylinders are fixedly connected to the corresponding connecting plates.

[0014] Preferably, a second protective shell is installed on the front side of the housing, and a first protective shell is installed on the housing. The first transmission component, the second transmission component, the short rod and the bevel gear are all located inside the first protective shell, and the servo motor is located inside the second protective shell.

[0015] A charging module includes a module body, docking terminals, a limiting flange, and a heat dissipation component. The module body adopts a cuboid encapsulation structure and can be stably installed in the housing using any of the above-described mounting structures.

[0016] The present invention has the following beneficial effects: 1. Compared with existing technologies, this invention achieves automated conveying and positioning of charging modules through a downward-moving module, significantly improving the efficiency of multi-module palletizing and installation. By driving the rotating shaft, transmission rollers, and conveyor belt with a servo motor, the charging modules can be smoothly moved to the placement platform. The entire process requires no manual intervention, and the synchronization of the transmission components ensures the consistency of the installation positions of multiple modules, effectively reducing the incidence of problems such as poor contact at the docking terminals. 2. Compared with the prior art, the lower end of the shrink block of the shrink assembly is set as an arc surface. The charging module squeezes the shrink block to slide along the shrink box and compresses the first spring, so that the module falls stably on the placement platform and separates from the shrink block. After the module falls to the stacking position, when the shrink block is no longer obstructed, the shrink block resets under the action of the first spring force. 3. Compared with the prior art, the side protection component of the present invention is linked with the transmission system to realize the automatic start and stop of the protection function, which not only improves safety but also simplifies the operation process. Through the cooperation of gears, racks and pinions, the opening and closing of the side guard plate is synchronized with the operation of the conveyor belt. During the module conveying process, the side guard plate is located below and automatically closes after the module is in place to achieve protection without additional manual operation, thus improving the ease of use. 4. Compared with the prior art, the present invention achieves precise positioning and stable fixation of the charging module through the synergistic effect of the cylinder-driven side alignment plate and the shrinking component, thereby improving the reliability of the installation structure. The arc surface at the upper end of the side guard plate allows for calibration of the left and right sides of the charging module when the side guard plate moves up. The cylinder pushes the side alignment plate to perform secondary calibration of the module from both sides, avoiding electrical connection failures caused by displacement.

[0017] In summary, this invention effectively solves the problems of low efficiency, stacking jams, cumbersome operation, and inaccurate positioning in existing charging module installations by organically integrating an automated lowering module, an adaptive shrinking component, a linked side protection component, and a dual precision calibration mechanism. It not only achieves automated and standardized stacking of multiple modules but also improves installation stability and equipment safety through multiple protection mechanisms, reducing labor costs and maintenance risks. It meets the development needs of large-scale and intelligent charging equipment and has significant practical value and promising prospects for widespread application. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Reference Figure 1-7 An installation structure for a charging module includes a housing 1, which is integrally die-cast from high-strength aluminum alloy. The inner wall of the housing 1 is coated with an insulating and thermally conductive coating, which can effectively improve insulation performance and heat dissipation efficiency. Multiple fixing plates 23 are fixedly connected to the inner walls of the front and rear sides of the housing 1. The multiple fixing plates 23 are jointly fixedly connected to a placement platform 15. The front side of the housing 1 is provided with an insertion port. The size of the insertion port is adapted to the main body of the charging module. The edge of the insertion port is provided with a rounded corner structure to prevent the module from being scratched when it is inserted. A cover plate 2 is rotatably connected to the front side of the insertion port via a hinge. The edge of the cover plate 2 that contacts the housing 1 is provided with a rubber sealing gasket. A mechanical lock is installed on the cover plate 2 to achieve a firm closure of the cover plate 2. A second protective shell 27 is installed on the front side of the housing 1, and a first protective shell 26 is installed on the housing 1. The lowering module includes four rotating shafts 4, four drive rollers 11, a servo motor 3, and multiple shrinking components. The two ends of the four rotating shafts 4 are rotatably connected to the inner walls of the front and rear sides of the housing 1. The two ends of the rotating shafts 4 are connected to the housing 1 via deep groove ball bearings. The outer ring of the bearing is interference-fitted with the mounting holes on the inner wall of the housing 1. The four drive rollers 11 are fixedly connected to their corresponding rotating shafts 4. Every two mating drive rollers 11 are connected by a conveyor belt 12. The conveyor belt 12 is a polyurethane synchronous belt with anti-slip textures on its surface. The tension of the conveyor belt 12 can be adjusted by adjusting the bearing seat position. Multiple shrinking components are installed... On the left and right sides of the corresponding conveyor belt 12, two shrinking components are grouped together. A gearbox is provided on the rear inner wall of the housing 1. The gearbox is used to change the rotation direction of the left and right rotating shafts 4, but does not change the speed. The rotating shaft 4 on the right side is fixedly connected to the output shaft of the gearbox, and the rotating shaft 4 on the left side is connected to the input shaft of the gearbox through the first transmission component 5. The first transmission component 5 is a synchronous belt transmission mechanism, including two synchronous pulleys and a synchronous belt. The servo motor 3 is installed on the front side of the housing 1. The servo motor 3 is fixedly connected to the rotating shaft 4 on the left side. The servo motor 3 is located inside the second protective shell 27.

[0022] The shrinking assembly includes a shrink box 13, a shrink block 14 is slidably connected inside the shrink box 13, and the shrink block 14 is elastically connected to the inner wall of the shrink box 13 near the conveyor belt 12 by a first spring 33. A side plate 40 is fixedly connected to the shrink block 14, the side plate 40 is perpendicular to the shrink block 14, and a soft rubber pad is pasted on the side that contacts the charging module.

[0023] The system also includes a side protection assembly, which consists of two side guards 16 located on the left and right sides of the placement platform 15, respectively. Multiple first slide rails 17 are fixedly connected to the bottom of the housing 1, and sliders 18 are slidably connected to each of the multiple first slide rails 17. Each slider 18 is fixedly connected to a connecting block 19, and each connecting block 19 is fixedly connected to the lower end of the corresponding side guard 16. Racks 20 are fixedly connected to the front of the two sliders 18 located on the rear side. Rotating rods 22 are rotatably connected to the inner walls of the left and right sides of the housing 1. Two gears 21 are fixedly connected to the rotating rods 22, and the two gears 21 mesh with the corresponding racks 20.

[0024] The placement platform 15 has two rectangular openings 28 on both the left and right sides. The edges of the rectangular openings 28 are deburred to prevent scratching the side guards 16. The upper ends of the two side guards 16 are beveled, and each side guard 16 has a vertical opening 29 that corresponds to the rectangular opening 28. The size of the vertical opening 29 is perfectly matched with the rectangular opening 28. When the side guard 16 moves upward, the rectangular opening 28 and the vertical opening 29 can form a through structure to avoid mutual interference. The lower ends of the multiple shrink blocks 14 are all arc surfaces. The arc surfaces are polished and the surface roughness Ra is no more than 0.8μm, which can reduce the frictional resistance with the charging module.

[0025] The left side of the housing 1 is fixedly connected to a bearing seat, on which a short rod 7 is installed. The short rod 7 is connected to the rotating shaft 4 located on the left side through a second transmission assembly 6. The second transmission assembly 6 is a chain drive mechanism, including two sprockets and a chain. The right side of the housing 1 is rotatably connected to a transmission rod 9. The transmission rod 9 is connected to the rotating rod 22 through a connecting assembly. Both the short rod 7 and the transmission rod 9 are provided with meshing bevel gears 10. Two pressure sensors 25 are installed at the upper end of the placement platform 15. The first transmission assembly 5, the second transmission assembly 6, the short rod 7 and the bevel gears 10 are all located inside the first protective shell 26, and a control assembly is provided outside. When multiple charging modules are completely placed on the placement platform, the pressure sensors 25 generate an electrical signal that is transmitted to the control assembly. The control assembly controls the two cylinders 31 to stretch, and at the same time, the electromagnet 39 is energized. When the charging modules are removed, the control assembly can control the electromagnet 39 to remain energized during the removal process. The connecting assembly includes a rectangular groove 37 on the left side of the rotating rod 22, a movable groove 38 on the right side of the transmission rod 9, an electromagnet 39 installed on the left inner wall of the movable groove 38, and a rectangular block 36 slidably connected inside the movable groove 38. The rectangular block 36 is made of magnetic material. When the electromagnet 39 is energized, it generates a repulsive force on the rectangular block 36. The adjacent sides of the rectangular block 36 and the electromagnet 39 are elastically connected by a second spring 35. In the initial state, the rectangular block 36 is located between the rotating rod 22 and the transmission rod 9.

[0026] Among them, cylinders 31 are installed on the inner walls of the front and rear sides of the housing 1, and second slide rails 24 are fixedly connected to the upper ends of multiple fixed plates 23. Side alignment plates 30 are slidably connected to multiple second slide rails 24. A connecting plate 32 is fixedly connected to the adjacent sides of every two cooperating side alignment plates 30. The telescopic ends of the two cylinders 31 are fixedly connected to the corresponding connecting plates 32.

[0027] A charging module includes a module body, docking terminals, limiting flanges, and heat dissipation components. The module body adopts a cuboid encapsulation structure and can be stably installed in the housing 1 using any of the above-mentioned mounting structures.

[0028] The functional principle of this invention can be explained through the following operation: When the device is in the initial state, the cover plate 2 is in the open state via the hinge, providing a reserved channel for the charging module; the servo motor 3 of the lowering module is in the standby state, the conveyor belt 12 remains stationary, and the shrinking block 14 of the shrinking assembly extends partially outside the shrinking box 13 under the elastic force of the first spring 33, with the side plate 40 in the initial limiting position; the side guard plate 16 of the side protection assembly is positioned below the placement platform 15 under the linkage of the gear 21 and rack 20, preventing obstruction of module conveying; the cylinder 31 is in the retracted state to prevent interference with module entry. Simultaneously, the electromagnet 39 in the connecting assembly is not energized, and the rectangular block 36 retracts into the moving groove 38 of the transmission rod 9 under the action of the second spring 35, not embedding in the rectangular groove 37 of the rotating rod 22, keeping the transmission rod 9 and the rotating rod 22 disconnected. At this time, power cannot be transmitted from the transmission rod 9 to the rotating rod 22, and the side guard plate 16 maintains its initial low position.

[0029] During the charging module placement and conveying operation, the charging module to be installed is placed on multiple shrink blocks 14 through the placement inlet on the front side of the housing 1, with the sides of the charging module initially attached to the side plates 40 on the left and right sides of the conveyor belt 12. The servo motor 3 is started, driving the left-side rotating shaft 4 to rotate. The left-side rotating shaft 4 drives the corresponding right-side rotating shaft 4 to rotate synchronously through the first transmission component 5 and the gearbox. The four rotating shafts 4 drive the transmission rollers 11 on them, thereby causing the two conveyor belts 12 to move synchronously and smoothly. The two conveyor belts 12 convey in opposite directions, transporting the charging module towards the placement platform 15 on the lower side of the housing 1. During this process, the precise control of the servo motor 3 ensures the stable operating speed of the conveyor belts 12, keeping the charging module moving horizontally and preventing positional deviation. The fixed plate 23 provides stable support for the placement platform 15, providing a reliable foundation for subsequent module stacking.

[0030] As the charging module moves above the placement platform 15, the curved surface of the shrink block 14 contacts the placement platform 15 as the conveyor belt 12 continues to operate. The curved surface guides the smooth compression of the shrink block 14, causing it to slide along the shrink box 13 towards the conveyor belt 12 and compress the first spring 33. This allows the charging module to fall completely to the stacking position on the placement platform 15, separating it from the shrink block 14. As the conveyor belt 12 continues to operate, when the shrink block 14 is no longer obstructed, it resets under the elastic force of the first spring 33. If multi-layer stacking is required, the above placement and conveying steps are repeated. Subsequent falling modules will be stacked under the support of the fixed modules below.

[0031] During the process of the servo motor 3 driving the rotating shaft 4 to rotate the conveying module, the rotating shaft 4 on the left side drives the short rod 7 to rotate through the second transmission component 6. The short rod 7 drives the transmission rod 9 to rotate synchronously through the meshing bevel gear 10. However, since the transmission rod 9 and the rotating rod 22 are separated at this time, the rotating rod 22 and the gear 21 remain stationary, and the side guard plate 16 always stays below the placement platform 15 to ensure that the module conveying channel is unobstructed.

[0032] After multiple charging modules have been stacked and placed in the designated position on the placement platform 15, the pressure sensor 25 generates a signal that is transmitted to the peripheral control component. The control component then energizes the electromagnet 39 of the connecting component. The electromagnet 39 generates a magnetic repulsive force, pushing the rectangular block 36 to slide outward along the moving groove 38 and stretching the second spring 35. This causes one end of the rectangular block 36 to embed into the rectangular groove 37 of the rotating rod 22, thus connecting the transmission rod 9 and the rotating rod 22. At this time, the power of the transmission rod 9 is transmitted to the rotating rod 22 through the rectangular block 36, causing the rotating rod 22 and its two gears 21 to rotate. Through the meshing of the gears 21 and the rack 20, the slider 18 on the rear side is driven to slide forward along the first slide rail 17. The slider 18 drives the side guard plate 16 to move upward synchronously through the connecting block 19. During the upward movement, the inclined surface at the upper end of the side guard plate 16 contacts the left and right sides of the charging module, and the inclined surface guides the module for preliminary calibration to ensure that the module is aligned left and right. When the side guard plate 16 moves up to the designated height, it provides full protection for all stacking modules from both sides. The bearing seat on the left side of the housing 1 provides stable rotation support for the short rod 7, ensuring smooth power transmission.

[0033] Simultaneously, the control component operates the cylinders 31 on both the front and rear sides of the housing 1. The telescopic ends of the cylinders 31 push the connecting plate 32 to move. The connecting plate 32 drives the side alignment plate 30 to slide along the second slide rail 24 towards the charging module. The side alignment plate 30 performs a second precise calibration on the module from both the front and rear sides to ensure alignment of the module and accurate docking of the terminals. After calibration, the cylinders 31 remain in a stretched state, allowing the side alignment plate 30 to continuously apply a clamping force to the module, closing the cover plate 2 and completing the entire installation and fixing process of the charging module.

[0034] When it is necessary to remove the charging module, the servo motor 3 is controlled to drive the rotating shaft to rotate in the opposite direction, thereby causing the shrink block to move in the opposite direction, lifting the charging module, and taking the charging module out through the inlet in sequence. At the same time, since the electromagnet 39 is still energized, the rotating rod 22 and the transmission rod 9 are connected, causing the two side guard plates 16 to move to the bottom of the placement platform 15, which is convenient for the next placement of the charging module.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
