Description

Technical Field

[0001] This utility model belongs to the field of battery swapping station technology, specifically relating to a rack-type charging compartment for a battery swapping station. Background Technology

[0002] With the rapid development of the new energy vehicle industry, battery swapping stations, as a core infrastructure for solving the problem of electric vehicle charging efficiency, are facing an increasingly urgent need for large-scale and efficient operation. As the core asset of a battery swapping station, the safety and efficiency of its storage and charging processes directly determine the station's service capacity and operating costs. However, current battery charging and storage devices within battery swapping stations, especially their cooling systems, suffer from numerous technical bottlenecks, making it difficult to adapt to the needs of large-scale battery management.

[0003] Battery swapping stations are mostly located outdoors or in semi-open environments, where there is a lot of dust and debris in the air. Battery charging components (such as electrode contacts and charging interfaces) require extremely high cleanliness. If dust adheres to the contact surfaces, it increases contact resistance, leading to increased localized heat generation during charging and potentially causing short circuits, leakage, and other safety hazards. Traditional heat dissipation solutions often rely on open cooling structures (such as large, unobstructed vents). While this improves heat dissipation, external dust and debris can directly enter the compartment and adhere to the battery surface and charging components, requiring significant monthly manpower for cleaning and maintenance; otherwise, charging malfunctions are likely. Sealed cooling structures reduce dust intrusion through a sealed compartment, but this significantly reduces heat dissipation efficiency, and high temperatures can still occur when charging multiple batteries. Utility Model Content

[0004] The purpose of this utility model is to provide a rack-type charging compartment for a battery swapping station that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A rack-type charging compartment for a battery swapping station includes a base, characterized in that: a shell frame is installed on the top of the base, a battery charging rack is fixedly installed inside the shell frame, the battery charging rack is provided with a plurality of arrayed batteries, each battery's input terminal is plugged into and plugged into a battery plugging and unplugging assembly, a heat dissipation assembly is provided on the front side wall of the shell frame, and a heat dissipation grille that cooperates with the heat dissipation assembly is fixedly installed on the rear side wall of the shell frame.

[0006] As a further optimization of this utility model, the heat dissipation assembly includes support blocks fixedly installed on both sides of the top of the front side wall of the outer shell frame. A rotating rod is rotatably connected between the two support blocks. A door is fixedly sleeved on the outer side wall of the rotating rod. Several arrayed heat dissipation fans are fixedly installed on the front side wall of the door.

[0007] As a further optimization of this utility model, a protective box is fixedly installed on the side wall of any of the support blocks, and a drive motor is fixedly installed on the inner side wall of the protective box. The output end of the drive motor is fixedly connected to one end of the rotating rod.

[0008] As a further optimization of this utility model, recessed strips are fixedly installed on the top front and rear sides of the outer shell frame, the two recessed strips are symmetrically distributed, and a dustproof plate is inserted between the two recessed strips.

[0009] As a further optimization of this utility model, a PLC control cabinet located on the side wall of the battery charging rack is fixedly installed on the top of the base. The PLC control cabinet is electrically connected to the drive motor, the battery plug-in assembly, and the cooling fan.

[0010] As a further optimization of this utility model, a scissor-fork type support rod is fixedly installed at the top of the inner side wall of the outer shell frame. The scissor-fork type support rod is located below the dustproof plate. All four corners of the bottom of the base are fixedly installed with universal wheels that have a self-locking function.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model adopts a composite heat dissipation design of "active air supply + passive air exhaust + opening and closing assistance" to solve the contradiction between heat dissipation and dust prevention: the heat dissipation fan actively supplies air into the chamber, and together with the heat dissipation grille, forms a front-to-back airflow to quickly dissipate heat. Compared with traditional natural ventilation, the heat dissipation efficiency is greatly improved. The heat dissipation grille on the rear side of the outer shell frame serves as a passive air exhaust channel, forming a front-to-back airflow circulation path with the heat dissipation fan, avoiding heat accumulation in the chamber, and solving the problems of dust accumulation in open charging chambers and poor heat dissipation efficiency in closed charging chambers.

[0012] 2. This utility model perfectly balances heat dissipation and dust prevention requirements through the combination of the cabinet door and the heat dissipation grille: During normal charging, the cabinet door is in the closed state, and heat dissipation is achieved only through the directional airflow channel formed by the heat dissipation fan and the heat dissipation grille. The cabinet door can block most of the external dust from entering; the heat dissipation grille itself has a certain dustproof pore design, which, together with the top dustproof plate, can filter larger particles of debris, further reducing dust intrusion, avoiding charging component failures caused by dust, extending the service life of the battery and charging components, and reducing the maintenance frequency.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1: As Figure 1 , Figure 2 As shown, a rack-type charging compartment for a battery swapping station includes a base 1, which serves as the supporting foundation for the entire device. Each of the four corners of the base 1 is fixedly equipped with a self-locking caster wheel 12. When it is necessary to adjust the position of the charging compartment within the battery swapping station, the self-locking state of the caster wheel 12 is released, allowing the charging compartment to be moved flexibly. Once the compartment reaches the designated position, the caster wheel 12 is locked to ensure stable placement of the charging compartment, effectively improving the site adaptability of the device.

[0017] like Figure 2 As shown, a shell frame 2 is installed on the top of the base 1. The shell frame 2 is welded from high-strength steel to form a closed frame structure, providing reliable protection and support for the internal components. A battery charging rack 13 is fixedly installed inside the shell frame 2. The battery charging rack 13 adopts a multi-layer shelf design, on which several arrays of batteries 14 are arranged. Each group of batteries 14 corresponds to an independent placement station, which can realize the simultaneous storage and charging of multiple batteries, greatly increasing the battery capacity of the battery swapping station. Each battery 14 has a battery plug-in component 15 pluggable to its input end. The battery plug-in component 15 adopts a standardized interface design, which allows staff or automated equipment to quickly connect or disconnect the battery 14 from the charging circuit, simplifying the battery loading and unloading process and improving the efficiency of battery swapping and charging.

[0018] like Figure 1 - Figure 4As shown, the front sidewall of the outer shell frame 2 is provided with a heat dissipation component, and the rear sidewall is fixedly installed with a heat dissipation grille 17 that cooperates with the heat dissipation component, forming a heat dissipation channel that runs through the front and rear. The heat dissipation component includes support blocks 8 fixedly installed on both sides of the top of the front sidewall of the outer shell frame 2. A rotating rod 9 is rotatably connected between the two support blocks 8. A door 7 is fixedly fitted on the outer sidewall of the rotating rod 9. The door 7 can rotate freely around the rotating rod 9 to open and close the front side of the charging compartment. Opening the door 7 makes it convenient for staff to inspect the internal components or install or remove the battery 14. Closing the door 7 can protect the internal battery 14 from external dust and rain. Several arrayed heat dissipation fans 6 are fixedly installed on the front sidewall of the door 7. After the heat dissipation fans 6 are started, they can accelerate the airflow inside the charging compartment and exhaust the heat generated by the charging of the battery 14 through the heat dissipation grille 17 on the rear sidewall of the outer shell frame 2 to achieve efficient cooling and prevent the battery 14 from being affected by high temperature in terms of charging efficiency or service life.

[0019] like Figure 1 - Figure 3 As shown, a protective box 5 is fixedly installed on the side wall of any support block 8. The protective box 5 adopts a waterproof and dustproof design. A drive motor 10 is fixedly installed on its inner side wall. The output end of the drive motor 10 is fixedly connected to one end of the rotating rod 9. When it is necessary to open or close the box door 7, the drive motor 10 drives the rotating rod 9 to rotate, thereby causing the box door 7 to rotate around the rotating rod 9. No manual operation is required, which improves the automation level of the device.

[0020] like Figure 1 - Figure 4As shown, recessed strips 3 are fixedly installed on the top front and rear sides of the outer shell frame 2. The two recessed strips 3 are symmetrically distributed, and the grooves of the recessed strips 3 are set opposite each other. A dustproof plate 4 is inserted between the two recessed strips 3. The dustproof plate 4 is made of transparent acrylic material or metal mesh, which can effectively block external dust from entering the charging compartment and prevent dust from adhering to the surface of the battery 14 or charging components and affecting performance. At the same time, it does not block the light from entering, making it easy for staff to observe the charging status of the internal battery 14. At the same time, the dustproof plate 4 is installed by plugging, and can be directly pulled out from the recessed strip 3 when cleaning or replacement is required, which is convenient. A scissor-fork support rod 16 is fixedly installed on the top of the inner side wall of the outer shell frame 2. The scissor-fork support rod 16 is located below the dustproof plate 4. Its two ends are connected to the two side walls of the outer shell frame 2, which can provide stable support for the dustproof plate 4, prevent the dustproof plate 4 from bending and deforming due to its own weight or external pressure, and extend the service life of the dustproof plate 4. The top of the base 1 is also fixedly installed with a PLC control cabinet 11 located on the side wall of the battery charging rack 13. The PLC control cabinet 11 is electrically connected to the drive motor 10, the battery plug-in assembly 15 and the cooling fan 6. The operator can set the charging parameters, control the start and stop and speed of the cooling fan 6, and drive the opening and closing of the box door 7 through the PLC control cabinet 11. At the same time, the charging voltage, current and temperature of the battery 14 are monitored in real time. When an abnormal situation occurs, the PLC control cabinet 11 can automatically cut off the charging circuit and issue an alarm to ensure that the charging process is safe and reliable.

[0021] It should be noted that, in use, the base 1 of this rack-type charging compartment of the battery swapping station serves as the basic support component of the device. The four corner casters 12 at the bottom of the base provide mobility for the charging compartment. When the self-locking state of the casters 12 is released, the staff can push the entire charging compartment to flexibly adjust its position within the battery swapping station to adapt to different battery storage and charging layout requirements. After reaching the designated area, the braking mechanism of the casters 12 is locked, and the rotation of the wheels is restricted by friction, so that the charging compartment is kept in a stable position, avoiding the impact of device displacement on battery connection stability during charging. The outer frame 2 forms a closed frame based on the base 1, providing rigid support for internal battery charging racks 13, batteries 14 and other components, while isolating external environmental interference and ensuring the safety of internal components.

[0022] The battery charging rack 13 adopts a multi-layer shelf structure, providing an independent array-style placement station for the batteries 14, enabling parallel storage and charging of multiple batteries. When charging the batteries 14 is required, the input terminal of the batteries 14 can be quickly connected to the charging circuit through the standardized interface of the battery plug-in component 15. The contact-type design of the plug-in component eliminates the need for complex wiring. Workers or automated equipment only need to push the batteries 14 into the station and complete the plug-in / plug-out action to establish a charging circuit. After charging is completed, the connection can be disconnected by reversing the operation, and the fully charged batteries 14 can be removed, which greatly simplifies the battery loading and unloading process and improves the efficiency of battery swapping and charging.

[0023] During the charging process, battery 14 generates heat. If the heat accumulates, it can cause the battery temperature to rise, affecting charging efficiency and lifespan. Therefore, the device achieves temperature control through a coordinated heat dissipation structure of "active air supply + passive air exhaust": After the cooling fan 6 on the front side wall of the door 7 is started, it generates directional airflow and sends air into the charging compartment, pushing the internal airflow. The cooling grille 17 on the rear side wall of the outer shell frame 2 serves as an exhaust channel, forming a through airflow path with the cooling fan 6 to quickly expel the heat generated by battery 14 and reduce the internal temperature of the charging compartment. The opening and closing function of the door 7 further assists in heat dissipation: When maintenance is required in the charging compartment, the drive motor 10 drives the rotating rod 9 to rotate, causing the door 7 to open around the rotating shaft between the support blocks 8. When charging normally, the door 7 is closed, which can reduce the entry of external dust and ensure the air supply efficiency of the cooling fan 6.

[0024] As the control core of the entire device, the PLC control cabinet 11 achieves intelligent control of various components through electrical connections. On the one hand, it can set parameters such as charging voltage, current, and duration to control the on / off state of the battery plug-in assembly 15 and precisely manage the charging process of the battery 14. On the other hand, it collects charging data of the battery 14 in real time, such as voltage, current, temperature, and the operating status of the cooling fan 6. When the battery temperature is too high or the current is abnormal, it automatically cuts off the charging circuit to prevent the battery from being overloaded or damaged. At the same time, it triggers an alarm to remind the staff to handle the situation. In addition, the dustproof plate 4 on the top of the outer frame 2 is fixed by the recessed strip 3, which can block the external dust from entering the charging compartment and prevent dust from adhering to the surface of the battery 14 and the charging assembly, affecting the conductivity. The scissor-fork support rod 16 below provides rigid support through the cross rods, dispersing the force on the dustproof plate 4 and preventing it from deforming due to its own weight or external pressure, thus ensuring the stability of the protection function. The protective box 5 forms a sealed protection for the drive motor 10, preventing rainwater and dust from entering the motor and ensuring the reliable operation of the automatic opening and closing function of the box door 7.

[0025] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
