Description

Technical Field

[0001] This utility model relates to the field of battery swapping station technology, and in particular to a noise reduction assembly for a battery swapping station and a battery swapping station. Background Technology

[0002] Battery swapping stations are used to swap batteries for new energy vehicles to achieve rapid energy replenishment. Battery swapping stations are usually large in size, and many of the working devices inside the station generate a lot of noise during operation. Taking the charging equipment as an example, the charging equipment can charge the battery packs stored in the battery swapping station in preparation for subsequent battery swapping operations. Due to the huge storage capacity of the battery packs in the station and the large number of charging devices, the charging equipment generates a lot of noise during the charging process. If the noise is directly discharged outside the station, it will cause noise pollution and easily affect the normal life of the surrounding residents, which can easily lead to noise complaints, resulting in poor practicality of the battery swapping station. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a noise reduction assembly for a battery swapping station and a battery swapping station, which has a simple structure and can effectively reduce the noise generated by the battery swapping station, thereby improving the practicality of the battery swapping station.

[0004] This utility model provides a noise reduction assembly for a battery swapping station, including a soundproof shell. The soundproof shell is disposed on one side of the main body of the battery swapping station and covers at least the outside of the air outlet of the main body. The soundproof shell includes a functional cavity that communicates with the air outlet. An air guide component and a noise reduction component are disposed in the functional cavity. An exhaust port is provided on the soundproof shell that communicates with the functional cavity. The noise reduction component is disposed between the air guide component and the exhaust port.

[0005] The soundproof enclosure blocks noise directly emitted from the air outlet of the main unit. The air guide component directs heat from the air outlet to the noise reduction component, which in turn reduces noise from the air guide component. Together with the soundproof enclosure, they effectively reduce the noise emitted from the air outlet, thus minimizing the noise emitted by the battery swapping station. The exhaust port discharges the hot air processed by the air guide and noise reduction components, thereby achieving ventilation and heat dissipation of the functional cavity. This effectively reduces the noise emitted by the working equipment inside the main unit to the outside, reducing noise complaints and minimizing adverse impacts on the surrounding environment.

[0006] In one embodiment, the soundproof housing includes a first housing and a second housing, the first housing and the second housing are connected and cooperate to form the functional cavity, the first housing is installed on the side of the main body and at least covers the outside of the air outlet, the second housing is installed on the upper surface of the main body, and the exhaust port is opened on the second housing.

[0007] In one embodiment, the first housing includes a first component mounted on the side of the main body and a second component mounted on the upper surface of the main body. The second housing is connected to the second component, and the air guide assembly and the noise reduction assembly are installed inside the second component.

[0008] In one embodiment, the functional cavity is provided with a mounting partition for mounting the air guide assembly. The mounting partition divides the functional cavity into a first chamber and a second chamber. The first chamber and the second chamber are connected through the air guide assembly. The noise reduction assembly is installed in the second chamber, and the exhaust port is connected to the second chamber.

[0009] In one embodiment, the airflow assembly includes at least one cooling fan mounted on the mounting plate.

[0010] In one embodiment, the noise reduction component includes at least two noise-absorbing plates, with a functional interval between two adjacent noise-absorbing plates.

[0012] In one embodiment, the silencing plate has a flow guide at one end near the air guide assembly, and the flow guide has a guide slope at one end near the functional interval. The guide slope extends obliquely from the side near the air guide assembly toward the side near the adjacent silencing plate, so that the width of the flow guide gradually increases from the side near the air guide assembly toward the side away from the air guide assembly.

[0013] In one embodiment, the soundproof housing is detachably mounted on the main body.

[0014] In one embodiment, the soundproof housing is provided with an access door.

[0015] This utility model also proposes a battery swapping station, including a main body with an air outlet. The aforementioned noise reduction assembly for the battery swapping station is installed outside the air outlet. This design helps reduce noise emitted outside the station and improves heat dissipation efficiency, thus enhancing the overall environmental friendliness of the station.

[0016] In one embodiment, the main body includes a charging chamber, which is equipped with a charging device for charging a battery pack inside the main body. The air outlet is located in the charging chamber and is used to connect the charging chamber to the outside of the main body. Attached Figure Description

[0029] Battery swapping stations are used to swap batteries for new energy vehicles to achieve rapid energy replenishment. Battery swapping stations are usually large in size, and many of the working devices inside the station generate a lot of noise during operation. Taking the charging equipment as an example, the charging equipment can charge the battery packs stored in the battery swapping station in preparation for subsequent battery swapping operations. Due to the huge storage capacity of the battery packs in the station and the large number of charging devices, the charging equipment generates a lot of noise during the charging process. If the noise is directly discharged outside the station, it will cause noise pollution and easily affect the normal life of the surrounding residents, which can easily lead to noise complaints, resulting in poor practicality of the battery swapping station.

[0030] Charging equipment generates a lot of heat during operation. If this heat is not dissipated in time, it can easily lead to high temperatures inside the station, affecting the lifespan of the battery pack and charging equipment. In severe cases, it can even cause combustion or explosion accidents, thus affecting the safety of the battery swapping station and resulting in poor safety. Therefore, heat dissipation equipment is usually installed in the battery swapping station to cool the charging equipment. However, this heat dissipation equipment also generates a lot of noise during operation, which reduces the practicality of the battery swapping station.

[0031] As attached Figure 1 As shown, this utility model proposes a noise reduction assembly for a battery swapping station, including a soundproof housing 200. The soundproof housing 200 is disposed on one side of the main body 100 of the battery swapping station and installed on the main body 100. (See attached diagram.) Figure 2The main body 100 is provided with an air outlet 110, which is used to exhaust the heat generated by the working equipment inside the main body 100 to the outside of the main body 100, so as to realize the ventilation and heat dissipation of the working equipment. The soundproof shell 200 covers at least the outside of the air outlet 110 of the main body 100 so that the heat or noise discharged from the air outlet 110 can enter the interior of the soundproof shell 200. The soundproof shell 200 includes a functional cavity 210 and an exhaust port 220 communicating with the functional cavity 210. The functional cavity 210 is connected to the air outlet 110. The functional cavity 210 is provided with an air guide assembly 300 and a noise reduction assembly 400, and the noise reduction assembly 400 is located between the air guide assembly 300 and the exhaust port 220.

[0032] The heat and noise discharged from the air outlet 110 enter the functional cavity 210 and are blocked by the soundproof shell 200, which can prevent the noise from being directly discharged to the outside of the main body 100. The air guide component 300 is used to realize the exhaust function, which can transmit hot air and noise to the noise reduction component 400. The noise discharged from the air outlet 110 and the noise of the air guide component 300 during operation are transmitted to the noise reduction component 400 and discharged from the exhaust port 220 after being processed by the noise reduction component 400.

[0033] The soundproof housing 200 can block the noise directly emitted from the air outlet 110 of the main body 100. The air guide component 300 can guide the heat from the air outlet 110 to the noise reduction component 400. The noise reduction component 400 can reduce the noise of the air guide component 300 and work with the soundproof housing 200 to treat the noise emitted from the air outlet 110, thereby reducing the noise emitted by the battery swapping station. The exhaust port 220 can discharge the hot air treated by the air guide component 300 and the noise reduction component 400, thereby achieving ventilation and heat dissipation of the functional cavity 210. This can effectively reduce the noise emitted by the working equipment inside the main body 100 to the outside of the main body 100, reduce noise complaints, and reduce the adverse impact on the surrounding environment.

[0034] The soundproof housing 200 can be configured as a closed cavity structure, with an opening communicating with the air outlet 110 and an exhaust port 220. Alternatively, the soundproof housing 200 can be configured as a semi-open structure, with the soundproof housing 200 connected to the main body 100 and enclosing it to form a functional cavity 210. Those skilled in the art can select the specifications and structure of the soundproof housing 200 according to actual needs.

[0035] In an example scheme, as shown in the appendix Figure 2As shown, the soundproof housing 200 includes a first housing 201 and a second housing 202. The first housing 201 and the second housing 202 are connected and cooperate to form a functional cavity 210. The first housing 201 is installed on one side of the main body 100 and covers at least the outside of the air outlet 110. The second housing 202 is installed on the upper end face of the main body 100. The exhaust port 220 is opened on the second housing 202. This arrangement can extend the heat flow path from the air outlet 110, which can improve the noise reduction effect in conjunction with the air guiding component 300 and the noise reduction component 400. It also has a good heat dissipation effect. The position of the exhaust port 220 can be set according to the needs of the surrounding environment of the main body 100, thereby changing the exhaust direction of hot air and noise to further reduce the impact on nearby residents.

[0036] For example, the first housing 201 is vertically connected to the second housing 202.

[0037] For example, in conjunction with the appendix Figure 1 and attached Figure 4 The first housing 201 includes a first component mounted on one side of the main body 100 and a second component mounted on the upper end of the main body 100. The second housing 202 is mounted on the upper end of the main body 100 and connected to the second component. The exhaust port 220 is opened on the second housing 202. The air guide assembly 300 and the noise reduction assembly 400 are installed inside the second component. With this configuration, the direction of hot air and noise emission can be adjusted by disassembling and assembling the second housing 202, or by selecting a second housing 202 with a suitable opening position for the exhaust port 220, according to the actual location of the battery swapping station. This further reduces the impact on nearby residents, and there is no need to change the position of the air guide assembly 300 and the noise reduction assembly 400. The adjustment is convenient and improves the practicality and flexibility of the noise reduction assembly.

[0038] For example, the first housing 201 and the second housing 202 are detachably connected, for instance, by screwing. This arrangement facilitates assembly and maintenance and reduces transportation costs. Optionally, a seal is provided at the connection between the first housing 201 and the second housing 202. The seal ensures the airtightness of the functional cavity 210, preventing heat or noise from escaping from the connection and improving heat dissipation and noise reduction efficiency. In a preferred embodiment, the seal can be made of structural adhesive, which can both improve connection strength and ensure the airtightness of the connection.

[0039] For example, the first housing 201 and the second housing 202 may be integrally molded parts, or the first housing 201 and the second housing 202 may be spliced ​​parts composed of several plates.

[0040] As attached Figure 2 and appendix Figure 3As shown by the arrow, the hot air and sound energy from the air outlet 110 enter the first housing 201 under the guidance of the air guide assembly 300, and move upward to the second housing 202. After being processed by the noise reduction assembly 400, they are discharged from the functional cavity 210 through the exhaust port 220.

[0041] For example, the soundproof shell 200 is detachably connected to the main body 100, which facilitates transportation and assembly. The noise reduction assembly of the battery swapping station of this utility model can be installed on the main body 100 of the battery swapping station that needs noise reduction treatment. It can be applied to different battery swapping stations, has high flexibility, and has a simple structure with good applicability.

[0042] For example, a seal is provided between the soundproof housing 200 and the main body 100. More specifically, a seal is provided at the connection between the soundproof housing 200 and the main body 100 to ensure the airtightness of the functional cavity 210 and prevent heat or noise from the functional cavity 210 from being discharged from other locations besides the exhaust port 220, thereby improving heat dissipation and noise reduction efficiency. Optionally, the seal can be made of structural adhesive, which can both improve the connection strength and ensure the airtightness of the connection.

[0043] For example, in conjunction with the appendix Figure 1 and attached Figure 2 The soundproof enclosure 200 is equipped with an inspection door 230, which facilitates personnel to enter the soundproof enclosure 200 to maintain the air guide assembly 300 and the noise reduction assembly 400. More specifically, the inspection door 230 is located on the first housing 201.

[0044] In one example scheme, combined with appendix Figure 2 and attached Figure 3 The functional cavity 210 is equipped with a partition 240, which divides the functional cavity 210 into a first chamber and a second chamber. The partition 240 is used to install the air guide assembly 300. The first chamber and the second chamber are connected through the air guide assembly 300. The noise reduction assembly 400 is installed in the second chamber. The exhaust port 220 is connected to the second chamber. The heat and sound energy emitted from the air outlet 110 directly enter the first chamber and then enter the second chamber through the air guide assembly 300. After being processed by the noise reduction assembly 400, it is discharged from the functional cavity 210 through the exhaust port 220. The partition 240 can act as a barrier to prevent hot air from directly entering the second chamber without passing through the air guide assembly 300, which is beneficial to ensuring the heat dissipation effect. It can also concentrate the hot air through the air guide assembly 300 to be discharged at the noise reduction assembly 400, and also prevent sound energy from being directly discharged from the exhaust port 220 without treatment, which is beneficial to ensuring the noise reduction effect.

[0045] For example, the mounting plate 240 is detachably connected to the first housing 201 or the second housing 202, which facilitates assembly and maintenance of the air guide assembly 300.

[0046] In an example scheme, as shown in the appendix Figure 3 As shown, the air guide assembly 300 includes at least one cooling fan 310, which is mounted on the mounting plate 240. The cooling fan 310 can both draw air and dissipate heat, which helps to improve heat dissipation efficiency.

[0047] In an example scheme, as shown in the appendix Figure 3 As shown, the noise reduction component 400 includes at least two sound-absorbing plates 410. The positions of the sound-absorbing plates 410 correspond to the positions of the cooling fan 310 to ensure that the heat from the cooling fan 310 must be processed by the sound-absorbing plates 410 before it can be discharged. The at least two sound-absorbing plates 410 are spaced apart, and a functional gap 420 is provided between two adjacent sound-absorbing plates 410. The exhaust noise generated during the operation of the air guide component 300 and the noise emitted at the air outlet 110 are repeatedly refracted and absorbed by the cooperation of the sound-absorbing plates 410 and the functional gap 420, which can effectively reduce the noise. After the sound energy is processed by the sound-absorbing plates 410, it is discharged from the functional cavity 210 through the exhaust port 220.

[0048] For example, as shown in the appendix Figure 4 As shown, the sound-absorbing plate 410 is provided with a metal screen 430 at least at one end near the functional interval 420. The metal screen 430 can improve the noise reduction performance of the sound-absorbing plate 410, which is conducive to increasing the number of refractions of sound energy to weaken the sound energy, ensuring that the noise reduction component 400 can effectively reduce noise and eliminate the noise impact of the battery swapping station on the surrounding environment.

[0049] For example, as shown in the appendix Figure 3 As shown, the sound-absorbing plate 410 has a flow guide 440 at one end near the air guide assembly 300. The flow guide 440 has a guide slope 441 at one end near the functional interval 420. The guide slope 441 extends obliquely from the side near the air guide assembly 300 toward the side near the adjacent sound-absorbing plate 410, so that the width of the flow guide 440 gradually increases from the side near the air guide assembly 300 toward the side away from the air guide assembly 300. The setting of the guide slope 441 can guide the sound energy from the air guide assembly 300 to the adjacent sound-absorbing plate 410 to increase the number of refractions and thus improve the noise reduction efficiency.

[0050] Optionally, the flow guide 440 and the sound damper 410 are integrally formed.

[0051] Combined with appendix Figure 1 and attached Figure 2This utility model also proposes a battery swapping station, including a main body 100, an air outlet 110 on the main body 100, and the aforementioned battery swapping station noise reduction assembly installed outside the air outlet 110. By installing the battery swapping station noise reduction assembly on the main body 100, it is beneficial to reduce the noise emitted to the outside of the battery swapping station and improve the heat dissipation efficiency, thereby improving the environmental friendliness of the entire station.

[0052] In one example, the main body 100 has a charging chamber, which contains a charging device, or a charging device and a heat dissipation device. The charging device is used to charge the battery pack stored in the main body 100, and the heat dissipation device is used to cool the charging device to prevent it from overheating. An air outlet 110 is located on the main body 100 at a position corresponding to the charging chamber. The charging chamber is connected to the outside of the main body 100 through the air outlet 110 to achieve heat dissipation and ventilation. The aforementioned noise reduction assembly for the battery swapping station is installed outside the air outlet 110 and can handle the heat and noise generated by the charging device, which can effectively improve the practicality of the battery swapping station and reduce noise complaints.

[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
