Description

Technical Field

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

[0002] With the rapid development of the new energy vehicle industry, battery swapping has become an important part of the energy replenishment system because it can effectively solve the pain point of excessive charging time. As the core infrastructure of the battery swapping model, the operating efficiency and battery management capabilities of battery swapping stations directly affect the user's energy replenishment experience and the large-scale development of the industry. Among them, the battery rack, as the core equipment for battery storage, charging and turnover in the battery swapping station, plays a decisive role in the overall operating cost, safety, stability and adaptability of the battery swapping station. Therefore, it is necessary to design a battery rack for battery swapping stations.

[0003] Existing battery racks in battery swapping stations mostly adopt a fixed layer spacing and load-bearing space design, which can only accommodate specific models or sizes of batteries. When a new specification battery is introduced into the swapping station, the entire battery rack needs to be replaced, which not only increases equipment costs but also leads to the idle and wasteful use of existing equipment. Existing battery cooling methods in swapping stations are mostly natural cooling or simple direct fan blowing. The former has a slow cooling speed and cannot meet the rapid cooling requirements during battery charging, while the latter is prone to uneven airflow distribution, resulting in some batteries not being cooled in time and being in a high-temperature environment for a long time, which not only shortens the battery life but also poses a risk of thermal runaway. Utility Model Content

[0004] The purpose of this utility model is to provide a battery rack 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 battery rack for a battery swapping station includes a battery rack assembly. The battery rack assembly includes two U-shaped placement racks. Each of the two U-shaped placement racks has multiple placement racks that cooperate with it installed inside. Multiple charging mounting mechanisms that cooperate with the placement racks are slidably installed at the close ends of the two U-shaped placement racks. Air-cooling components are installed on both sides of the two U-shaped placement racks.

[0006] As a further optimization of this utility model, connecting plates are fixedly installed on both sides of the bottom of the two U-shaped placement racks that are close to each other, and limiting crossbars are fixedly installed on both ends of the top and the middle of the interior of the two U-shaped placement racks, and adjusting screws are fixedly installed on the middle of the top and the middle of the interior of the two U-shaped placement racks.

[0007] As a further optimization of this utility model, the placement frame includes multiple fixed plates that are fixedly installed outside the adjusting screw and placed on one side inside the U-shaped placement frame. Multiple movable plates placed inside the U-shaped placement frame are slidably fitted on the outside of the two limiting crossbars, and the multiple movable plates are fitted on the outside of the adjusting screw. At the middle position of the side of the multiple movable plates away from the fixed plate, an internal threaded sleeve block that is threadedly fitted on the outside of the adjusting screw is rotatably installed.

[0008] As a further optimization of this utility model, a placement plate is fixedly installed on the bottom of the multiple fixed plates on the side away from the U-shaped placement frame and on the bottom of the multiple movable plates on the side away from the fixed plates. A U-shaped sliding plate is fixedly installed on the bottom of the multiple movable plates on the side close to the fixed plates, and the multiple U-shaped sliding plates are placed outside the placement plate and slide against it.

[0009] As a further optimization of this utility model, the air-cooled assembly includes an installation chamber fixedly installed on one side of two U-shaped placement frames. A semiconductor cooling chip extending to the outside is threadedly installed inside the installation chamber on the side near the U-shaped placement frame. An air inlet pipe is threadedly installed inside the installation chamber. The input end of the air inlet pipe extends to the side of the installation chamber away from the U-shaped placement frame, and the output end of the air inlet pipe extends to the inner bottom of the installation chamber.

[0010] As a further optimization of this utility model, the air-cooling assembly also includes a flow guide chamber fixedly installed on the other side of the two U-shaped placement frames. The flow guide chamber has exhaust holes evenly opened on the side near the U-shaped placement frame. An air pump is threadedly fixedly installed on the top of one of the connecting plates. The input end of the air pump is fixedly connected to a connecting pipe. The end of the connecting pipe away from the air pump is placed at the bottom of the installation chamber and connected to the output end of the air inlet pipe. The output end of the air pump is fixedly connected to the inner bottom of the flow guide chamber.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model achieves flexible adaptation to batteries of different sizes through the adjustable structure of the placement rack. By utilizing the threaded engagement between the adjusting screw and the internal threaded sleeve, rotating the internal threaded sleeve drives the movable plate to slide along the adjusting screw, thereby adjusting the distance between the movable plate and the fixed plate. At the same time, the sliding fit design between the U-shaped sliding plate and the placement plate ensures that the placement plate remains horizontal during the spacing adjustment process, preventing the battery from tilting. This structure can cover a variety of size requirements from small passenger car batteries to medium-sized commercial vehicle batteries, adapting to different battery specifications without replacing the equipment, significantly reducing the equipment upgrade cost of the battery swapping station and improving equipment utilization.

[0012] 2. This utility model constructs a highly efficient heat dissipation function of "directional cooling + uniform airflow" through an air-cooling component, solving the problem of uneven heat dissipation. First, the semiconductor cooling chip actively cools the air in the installation chamber. Compared with the traditional fan blowing natural air, it can quickly reduce the airflow temperature to the safe operating temperature range of the battery. Second, the air inlet pipe guides the outside air into the installation chamber for cooling, and then it is pressurized by the air pump and sent into the airflow guiding chamber. Finally, the exhaust holes on the airflow guiding chamber, corresponding to the number of layers of the placement rack, blow the cooling air evenly to each layer of batteries, ensuring that each battery can come into contact with a stable cooling airflow, avoiding local overheating, and significantly improving battery safety and service life.

[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 2As shown, a battery rack for a battery swapping station includes a battery rack assembly 1, an air-cooling assembly 2, a placement rack 3, and a charging installation mechanism 4. The battery rack assembly 1 serves as the core support structure, providing a mounting base for other components. The air-cooling assembly 2 is symmetrically installed on both sides of the battery rack assembly 1, responsible for overall heat dissipation. The placement rack 3 is built into the battery rack assembly 1 to support the battery. The charging installation mechanism 4 is slidably mounted inside the battery rack assembly 1 and works with the placement rack 3 to achieve the battery charging function.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, the battery rack assembly 1 includes two symmetrically arranged U-shaped placement racks 100. The two U-shaped placement racks 100 are made of high-strength aluminum alloy to ensure structural stability. On both sides of the bottom of the two U-shaped placement racks 100, which are close to each other, a connecting plate 103 is fixedly installed by bolts. There are a total of two connecting plates 103 to achieve the fixed splicing of the two U-shaped placement racks 100 to form an overall frame. At the same time, at both ends of the top and the front and rear positions of each U-shaped placement rack 100, as well as at both ends and the front and rear positions of the inner middle position, a limiting crossbar 101 is fixedly installed by welding. There are a total of four limiting crossbars 101 installed in each U-shaped placement rack 100 to limit the lateral displacement of the placement rack 3 and the battery. In addition, at the center of the top and the middle layer of the inner middle position of each U-shaped placement rack 100 in the left and right directions, an adjusting screw 102 is fixedly installed by thread. There are a total of two adjusting screws 102 in each U-shaped placement rack 100 to provide a limiting function for the position adjustment of the placement rack 3.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, the placement racks 3 are evenly distributed in layers inside the two U-shaped placement racks 100. Each layer of the placement rack 3 includes a fixed plate 303, a movable plate 300, a U-shaped sliding plate 301, a placement plate 302, and an internally threaded sleeve 304. Multiple fixed plates 303 are respectively fixedly installed on the outside of the adjusting screw 102 by bolts, and are located on the side of the U-shaped placement rack 100 closer to the outside. Each of the two U-shaped placement racks 100 has two layers of placement racks 3 inside (the specific number of installation layers can be added by the operator according to the actual operation needs). Each layer of placement rack 3 has a fixed plate 303 fixedly installed inside, which serves as a fixed reference for battery placement. Multiple movable plates 300 slide and fit onto the limiting crossbar 10. 1. The outer side of the adjusting screw 102 and the inner side of the U-shaped placement rack 100 are opposite to the fixed plate 303. Each layer of the placement rack 3 has four movable plates 300 fitted inside (the specific number can be added according to the operator's needs; only four are shown in this figure). At the middle position of the side of each movable plate 300 away from the fixed plate 303, an internal threaded sleeve 304 is rotatably installed via a bearing. The internal threaded sleeve 304 is threadedly fitted with the adjusting screw 102. By rotating the internal threaded sleeve 304, the movable plate 300 can be driven to slide along the adjusting screw 102, thereby adjusting the distance between the movable plate 300 and the fixed plate 303 to accommodate batteries of different sizes.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, placement plates 302 are fixedly installed by welding on the bottom of multiple fixed plates 303 on the side away from the U-shaped placement frame 100 and on the bottom of multiple movable plates 300 on the side away from the fixed plate 303. The placement plates 302 are made of insulating material and are used to directly support the batteries. At the same time, U-shaped sliding plates 301 are fixedly installed on the bottom of multiple movable plates 300 on the side close to the fixed plate 303. The opening of the U-shaped sliding plate 301 faces the fixed plate 303 and fits around the outside of the placement plate 302 at the bottom of the fixed plate 303, sliding and adhering to the placement plate 302 to ensure that the placement plate 302 remains horizontal when the movable plate 300 slides, preventing the battery from tilting. The two ends of the placement plate 302 and the two ends inside the U-shaped sliding plate 301 are respectively provided with guide grooves and guide sliders. The guide sliders slide and guide grooves to improve the stability of the sliding displacement of the U-shaped sliding plate 301 and the placement plate 302 in the later stage.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, the charging installation mechanism 4 is slidably installed at one end of the two U-shaped placement racks 100 corresponding to the number of layers. Each layer corresponds to one charging installation mechanism 4. The end of the charging installation mechanism 4 near the U-shaped placement rack 100 is slidably connected to the slide rail behind the U-shaped placement rack 100 through a slider. The position can be adjusted by sliding in the left and right directions. At the same time, the charging interface of the charging installation mechanism 4 faces the placement rack 3. When the battery is placed on the placement plate 302, sliding the charging installation mechanism 4 can make the charging interface connect with the charging end of the battery to realize the battery charging function. The number of layers of the charging installation mechanism 4 and the placement rack 3 are one-to-one, ensuring that each battery can be charged independently.

[0021] like Figure 4 , Figure 5 As shown, the air-cooled assembly 2 is symmetrically installed on both sides of the two U-shaped mounting brackets 100, including a mounting chamber 200, a guide chamber 201, a connecting pipe 202, an air pump 203, a thermoelectric cooler 204, an exhaust port 205, and an air inlet pipe 206. The mounting chamber 200 is fixedly installed on the left side of one side of the two U-shaped mounting brackets 100 by bolts. Inside the mounting chamber 200, near the side of the U-shaped mounting bracket 100, the thermoelectric cooler 204 is fixedly installed by threads. The cooling end of the thermoelectric cooler 204 faces the inside of the mounting chamber 200, and the heat dissipation end extends to the outside of the mounting chamber 200. Meanwhile, the mounting chamber... An air inlet pipe 206 is threadedly installed inside the mounting chamber 200 via a pipe mounting bracket. The air inlet pipe 206 has a continuous bent shape design, which facilitates the extension of the subsequent air intake path and ensures the uniformity of external air cooling. The input end of the air inlet pipe 206 passes through the side wall of the mounting chamber 200 and extends to the left side of the mounting chamber 200 away from the U-shaped placement rack 100 to draw in outside air. The output end of the air inlet pipe 206 extends to the inner bottom of the mounting chamber 200, located below the cooling end of the semiconductor cooling chip 204, so that the drawn-in air can be cooled by the semiconductor cooling chip 204 before entering the subsequent channel.

[0022] like Figure 4 , Figure 5As shown, the flow guide chamber 201 is bolted to the right side of the other side of the two U-shaped placement racks 100, symmetrical to the installation chamber 200. The left side wall of the flow guide chamber 201 near the U-shaped placement rack 100 has evenly distributed exhaust holes 205 to ensure that cooling air can be evenly blown into the positions of the two U-shaped placement racks 100 near each other, facilitating cooling of the wiring and batteries installed inside the U-shaped placement racks 100. An air pump 20 is threadedly fixed to the top of one of the connecting plates 103. 3. The input end of the air pump 203 is fixedly connected to the connecting pipe 202 via a flange. The end of the connecting pipe 202 away from the air pump 203 is placed at the bottom of the installation chamber 200 and is connected to the output end of the air inlet pipe 206 via a threaded seal. The output end of the air pump 203 is fixedly connected to the inner bottom of the guide chamber 201 via a pipe, forming a heat dissipation airflow channel of "outside air → air inlet pipe 206 → installation chamber 200 cooling → connecting pipe 202 → air pump 203 → guide chamber 201 → exhaust port 205 → battery area".

[0023] It should be noted that when this battery rack for a battery swapping station is put into use, firstly, according to the size of the battery to be stored, the internal threaded sleeve 304 is rotated to drive the movable plate 300 to slide along the adjusting screw 102, adjusting the distance between the movable plate 300 and the fixed plate 303 so that the placement plate 302 forms a bearing space suitable for the battery. Then, the battery is placed on the placement plate 302, and the charging installation mechanism 4 of the corresponding layer is slid to connect the charging interface with the battery and start the charging program. At the same time, the movement of the sliding plate 300 driven by the internal threaded sleeve 304 can also limit and fix the placed battery, ensuring the stability of the battery placement in the later stage.

[0024] During the charging process, the air-cooling component 2 operates synchronously: after the semiconductor cooling chip 204 is powered on, its cooling end cools the air inside the installation chamber 200. At the same time, the air pump 203 starts and draws in outside air through the air inlet pipe 206. After being cooled in the air inlet pipe 206, the air enters the air pump 203 through the connecting pipe 202 and is then forced into the guide chamber 201. Finally, the cooled air is evenly blown towards the battery area through the exhaust port 205, carrying away the heat generated during the charging process and ensuring that the battery is always within a safe temperature range. Meanwhile, the air inlet pipe 206 is made of aluminum, and its bending design can complete the heat conversion between the outside air and the semiconductor cooling chip 204, and can also extend the transmission time of the outside air, ensuring the uniformity of cooling in the later stage and improving the cooling efficiency in the later stage.

[0025] In addition, the limiting crossbar 101 can ensure the stability of the sliding plate 300's subsequent driving displacement and provide load-bearing capacity for the sliding plate 300. The sliding cooperation between the U-shaped sliding plate 301 and the placement plate 302 ensures the stability of the battery bearing surface when the movable plate 300 is adjusted. The overall structure realizes the integration of battery storage, charging and heat dissipation, meeting the high-efficiency operation requirements of the battery swapping station.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
