For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] The embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application. Figures 1-3The battery pack of the battery swap station is described.

[0027] It is worth mentioning that the application field of the impurity removing device 100 is not limited, and the impurity removing device 100 can be applied to remove impurities for the battery pack in the battery swap, and can also be applied to the mechanical manufacturing, food processing and other industries. It is particularly suitable for scenes that need to clean and remove impurities from the bottom of the object.

[0028] As shown in Figure 1 , the impurity removing device 100 comprises a collecting box 10 and an impurity removing mechanism 20.

[0029] The collecting box 10 is suitable to be placed below the battery pack, and the top of the collecting box 10 has a collecting opening 101 to receive the falling impurities.

[0030] The collecting box 10 is located below the battery pack. Generally, the collecting box 10 is located directly below the battery pack so as to maximize the capture and collection of impurities falling from multiple directions of the battery pack.

[0031] Optionally, the collecting opening 101 of the collecting box 10 is not smaller than the size of the battery pack.

[0032] Specifically, the size and size of the collecting opening 101 can ensure that the collecting opening 101 can completely cover the bottom projection area of the battery pack, which means that the impurities falling below the battery pack, such as particles, dust or sewage sludge, can be guided into the collecting opening 101. In this way, the impurities are prevented from scattering outside the collecting box 10, reducing the complexity and labor intensity of subsequent cleaning work.

[0033] In combination with Figure 1 and Figure 2 , the impurity removing mechanism 20 is movably arranged on the collecting box 10. The impurity removing mechanism 20 comprises a cleaning body 21 for contacting the battery pack, and the bottom of the impurity removing mechanism 20 is communicated with the collecting opening 101.

[0034] During the impurity removing process, the cleaning body 21 is in contact with the surface of the battery pack as the impurity removing mechanism 20 moves. This contact not only promotes the effective falling of dirt on the surface of the battery pack, but also realizes the comprehensiveness and uniformity of the cleaning effect. At the same time, since the impurity removing mechanism 20 is directly communicated with the collecting box 10, the peeled impurities can immediately fall into the collecting box 10 below through the opening at the bottom of the impurity removing mechanism 20. This real-time collection mechanism not only avoids the scattering of impurities around the battery pack, but also avoids the accumulation of impurities in the impurity removing mechanism 20, ensures the clean environment and safe operation of the impurity removing site, and reduces the burden of subsequent cleaning work.

[0035] In addition, during the impurity removal process, due to the vibration of the battery pack surface and the cleaning action of the cleaning body 21, some impurities in areas not cleaned by the impurity removal mechanism 20 will also be loosened or peeled off. Once these impurities are detached from the battery pack surface, they will begin to fall due to gravity.

[0036] At this time, the collection box 10 is placed below the battery pack, and the top of the collection box 10 is open so that debris falling from areas not cleaned by the cleaning mechanism 20 can also fall into the collection box 10.

[0037] Therefore, whether it is debris directly swept down by the debris removal mechanism 20, or debris that falls off naturally due to vibration during the cleaning operation and is not released from the area directly cleaned, it can be captured and collected by the collection box 10 located below.

[0038] In summary, the impurity removal device 100 of this utility model embodiment has an efficient impurity collection mechanism, which takes into account both the cleanliness of the battery pack and the tidiness of the surrounding environment, and improves the convenience and practicality of battery pack impurity removal operations in battery swapping stations.

[0039] In some alternative embodiments, the cleaning body 21 may be a roller. The roller includes one or more cylindrical rollers, the surface of which is covered with a layer of soft or hard material. The roller is driven by a motor to rotate at a certain speed and direction, so that the material layer on its surface generates sufficient friction when it comes into contact with the surface of the battery pack, effectively removing dirt and dust to achieve a comprehensive and uniform cleaning effect.

[0040] Alternatively, the cleaning body 21 can also be a brush body. The brush body comprises a series of bristles or filaments. These bristles or filaments can be made of soft nylon, polyester, or other abrasion-resistant materials. Driven by a motor, the brush body brushes the surface of the battery pack. The bristles or filaments can penetrate deep into the crevices and grooves of the battery pack to remove hard-to-reach dirt and impurities, thus achieving a cleaning effect on the battery pack.

[0041] According to some embodiments of the present utility model, the impurity removal device 100, combined with Figure 1 and Figure 2 The cleaning body 21 includes at least one elastic block to be in a compressed state when in contact with the battery pack.

[0042] Specifically, when the elastic block comes into contact with the battery pack, its elastic properties cause it to naturally be in a slightly compressed state. This compression not only increases the contact area with the battery pack surface but also makes the contact tighter, thereby increasing friction and making it easier to remove dirt and impurities. Furthermore, the compression of the elastic block can also adapt to the unevenness of the battery pack surface to a certain extent, making cleaning more even and thorough.

[0043] Furthermore, the elastic block is a porous elastic block. The elastic block can be a latex block, rubber block, sponge block, etc. The choice of these materials can be determined according to specific cleaning needs, and no specific restrictions are imposed in this application.

[0044] In some embodiments, such as Figure 1 and Figure 2 The impurity removal device 100 further includes a first track 31 and a first drive device 32. The first track 31 extends along a first direction, and the impurity removal mechanism 20 is movably disposed on the first track 31. The first drive device 32 is connected to the impurity removal mechanism 20 to drive the impurity removal mechanism 20 to move along the first track 31.

[0045] Here, the first direction is the length direction of the battery pack. In some designs, the first direction can also be the width direction of the battery pack.

[0046] The first track 31 provides a stable and continuous movement path for the impurity removal mechanism 20, ensuring the smoothness and accuracy of the impurity removal mechanism 20 during movement.

[0047] Closely cooperating with the first track 31 is the first drive device 32, which is configured to drive the impurity removal mechanism 20 to move along the extension direction of the first track 31.

[0048] In some embodiments, the cleaning mechanism 20 is capable of reciprocating along the first track 31. This reciprocating movement ensures complete coverage and uniform cleaning of the battery pack surface, thereby guaranteeing a cleaning effect.

[0049] According to some embodiments of the present invention, the impurity removal device 100, such as Figure 1 and Figure 3 As shown, the impurity removal mechanism 20 includes a support base 22, which is movably mounted on a first track 31, and a cleaning body 21 is disposed on the support base 22. The first drive device 32 includes a first motor 321 and a first roller. The first motor 321 is disposed on the support base 22. The first roller is connected to the first motor 321 and is mounted on the first track 31 to move on the first track 31.

[0050] In the above technical solution, the support seat 22 in the cleaning mechanism 20 is used to support the weight of the cleaning body 21, and also enables the entire cleaning mechanism 20 to move flexibly during the cleaning process through movable cooperation with the first track 31.

[0051] The cleaning body 21 is mounted on the support base 22. In this way, when the support base 22 moves along the first track 31, it can drive the cleaning body 21 to perform cleaning operations along the extension direction of the first track 31.

[0052] The first drive unit 32 includes a first motor 321 and a first roller. The first motor 321 is mounted on the support base 22 and provides power for the movement of the support base 22. The first roller is connected to the first motor 321 via gears, chains or directly. When the first motor 321 is started, the roller rolls on the first track 31, thereby driving the entire impurity removal mechanism 20 to move.

[0053] Optionally, the parameters of the first drive device 32 are adjustable to control the moving speed and direction of the support 22, thereby improving the controllability of the cleaning body 21 in cleaning the battery pack.

[0054] Optionally, such as Figure 2 As shown, the cleaning body 21 is a long strip extending along the second direction, which forms an angle with the first direction.

[0055] This design allows the cleaning body 21 to better adapt to gaps of different shapes and positions between the battery pack and the vehicle body.

[0056] There is an angle between the second direction and the first direction, which means that the cleaning body 21 can better cover the surface of the battery pack during movement, thereby removing dirt and impurities more effectively.

[0057] To further enhance the cleaning effect and prevent debris from splashing, the debris removal mechanism 20 also includes mudguards 24 located on both sides of the cleaning body 21 in the first direction.

[0058] By setting these mudguards 24, it is possible to effectively block and prevent dirt and impurities stripped off by the cleaning body 21 from splashing, and guide the debris into the collection box 10.

[0059] At this time, the cleaning body 21 can be an elastic block, a roller, or a brush, etc.

[0060] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the impurity removal device 100 further includes a second track 41 and a second drive device 42. The second track 41 extends along a third direction, and there are two second tracks 41 located at both ends of the collection box 10. The two ends of the first track 31 are movably fitted onto the second track 41, and the third direction forms an angle with the first direction. The second drive device 42 is connected to the first track 31 to drive the first track 31 to move along the second track 41.

[0061] In the above technical solution, the second track 41 extends in a third direction, thereby providing an additional movement path for the cleaning mechanism 20. The second track 41 is constructed as two tracks, respectively located at both ends of the collection box 10. This design allows the first track 31 (and the cleaning mechanism 20 thereon) to move along the second track 41, thus achieving multi-directional cleaning of the battery pack.

[0062] It is worth noting that there is an angle between the third direction and the first direction. This angle is designed to ensure that the cleaning mechanism 20 can cover a wider area during movement.

[0063] The second drive unit 42 works in conjunction with the second track 41. It is responsible for driving the first track 31 (and the impurity removal mechanism 20 on it) to move along the second track 41. The second drive unit 42 may include components such as a motor, a transmission mechanism, and a control unit. They work together to ensure that the first track 31 can move smoothly and accurately along the second track 41.

[0064] In some specific applications, the operating state of the second drive unit 42 can be precisely controlled by changing the parameters of the control unit, including starting, stopping, accelerating, decelerating, and changing the direction of movement. In this way, the movement path and speed of the cleaning mechanism 20 can be flexibly adjusted according to the specific cleaning task requirements to achieve the best cleaning effect.

[0065] In some optional embodiments, the impurity removal device 100 further includes a water pipe (not shown). Combined with Figures 1-3 A water pipe is installed on the collection box 10, and the water pipe has a spray nozzle 431 facing the collection box 10.

[0066] The water pipe is installed on the collection box 10 so as not to interfere with the normal operation of the cleaning mechanism, and to ensure that the water nozzle 431 can be accurately directed toward the surface of the battery pack or the surface of the area to be cleaned.

[0067] Optionally, the cleaning medium flowing through the water pipe can be water, antifreeze, or cleaning fluid. Water, as a cleaning medium, is suitable for cleaning sticky dirt from the battery pack surface. In cold environments, antifreeze can be selected to prevent the battery pack from freezing against the vehicle body during the cleaning process, ensuring that the battery swapping operation is not affected by weather.

[0068] Optionally, the cleaning device 100 also includes a booster pump. The booster pump is used to increase the jet pressure of the cleaning medium, thereby enhancing the cleaning ability of the surface of the area to be cleaned.

[0069] In some alternative embodiments, such as Figures 1-3 As shown, the collection box 10 has multiple side walls 102, and a drain outlet 103 is provided at the bottom of the collection box 10. Each side wall 102 is inclined downward and connected to the drain outlet 103.

[0070] The multiple side walls 102 of the collection box 10 provide multi-directional enclosure for the collection area, ensuring that dirt and impurities shed during the cleaning process can be effectively collected. The side walls 102 are set at a certain angle to guide dirt to flow quickly towards the drain 103.

[0071] The drain outlet 103 is located at the bottom of the collection box 10 and serves as a channel for the discharge of dirt and impurities. This design allows dirt and impurities entering the collection box 10 to flow smoothly to and be discharged from the collection box 10 under the combined action of gravity and the inclined side wall 102, improving the continuity and stability of the cleaning operation.

[0072] To further improve cleaning efficiency, each sidewall 102 has at least one water nozzle 431. By controlling the number and position of the water nozzles 431, cleaning effects can be achieved in more directions.

[0073] The impurity removal device 100 according to some embodiments of the present invention further includes: an air jet device (not shown in the figure). The air jet device includes a drive motor, an air compressor, and an air pipe. The air pipe is mounted on the collection box 10 and has at least one upward-facing air hole 44. The air compressor is connected to the air pipe to inject gas, and the drive motor is used to drive the air compressor to work.

[0074] Specifically, when the drive motor starts and drives the air compressor, high-pressure gas is compressed and stored in the air pipe. Subsequently, this high-pressure gas is released at high speed onto the battery pack surface through the air vents 44 on the air pipe. The gas jet directly blows away dirt and impurities from the battery pack surface.

[0075] Optionally, the jet device can also be used in conjunction with the water nozzle 431 to create a gas-liquid mixture jet effect, further improving cleaning efficiency and cleaning quality.

[0076] In some alternative embodiments, the jet device further includes a heater disposed between the air compressor and the air pipe.

[0077] In some cold climates, battery packs may freeze on their surface due to low temperatures, making them difficult to remove quickly and smoothly from vehicles. Therefore, to address this issue, the present invention's cleaning device 100 integrates a heater into its jetting mechanism. This heater melts the ice layer on the battery pack surface by spraying hot air, thereby simplifying the battery swapping process and improving swapping efficiency.

[0078] Specifically, a heater is installed between the air compressor and the air pipe. When the jetting device is activated, the air compressor starts working, compressing outside air into high-pressure gas. This high-pressure gas then passes through the heater and is rapidly heated to a suitable temperature. The heated gas is then released onto the battery pack surface in the form of a high-speed jet through the air port 44 on the air pipe. The jetting of high-temperature, high-pressure gas not only directly acts on the ice layer, using its thermal energy to accelerate the melting process, but also carries away the melted ice water through the gas flow, preventing the ice layer from reforming. This design makes battery swapping more convenient in cold weather, providing users with a better battery swapping experience.

[0079] Optionally, the two side walls 102 of the collection box 10, arranged along the first direction, are each provided with a plurality of air holes 44. This arrangement allows the air holes 44 to blow hot air evenly from both sides toward the two longest sides of the battery pack. This ensures that areas around the battery pack that are susceptible to low temperatures and may freeze can quickly and comprehensively come into contact with the hot air, thereby effectively accelerating the melting of the ice layer and improving the efficiency of the battery swapping operation.
