Description

[0001] This application claims priority to international patent application No. PCT / CN2025 / 081429, filed on March 7, 2025, entitled “A battery swapping mechanism, a battery swapping station and a control method”, the entirety of which is incorporated herein by reference. Technical Field

[0002] This application relates to the field of battery technology, and in particular to a battery swapping mechanism and a battery swapping station. Background Technology

[0003] With the rapid development of new energy vehicles, energy replenishment technology is also constantly improving. Currently, energy replenishment for new energy vehicles mainly includes charging at charging piles and battery swapping at battery swapping stations. Charging at charging piles has drawbacks such as low charging efficiency, high space requirements, high battery maintenance costs, and reduced battery lifespan. Battery swapping, on the other hand, not only significantly improves energy replenishment efficiency but also requires less space and avoids the adverse effects on battery life caused by charging in suboptimal environments.

[0004] Directly replacing the batteries of new energy vehicles has become the mainstream development direction for energy replenishment. However, during the battery swapping process, an image acquisition device is needed to obtain the battery's status information. This information can then assist in performing the swapping operation. However, the image acquisition device is easily affected by impurities during battery image acquisition, making it difficult to accurately obtain battery information and ensuring the smooth progress of the swapping operation. Utility Model Content

[0005] The main purpose of this application is to provide a battery swapping mechanism and a battery swapping station, which aims to solve the aforementioned technical problems existing in the prior art.

[0006] To address the aforementioned problems, this application provides a battery swapping mechanism for removing and / or installing batteries in a vehicle. The mechanism includes an image acquisition device, a light-transmitting element, and a cleaning component. The image acquisition device acquires battery images, and the light-transmitting element is located in the optical path of the image acquisition device. The light-transmitting element includes a first surface and a second surface. The first surface faces the image acquisition device, and the second surface faces the vehicle. The cleaning component includes an air source component and a wiping component. The air source component sprays airflow onto the light-transmitting element, and the wiping component wipes the second surface of the light-transmitting element. Thus, the air source component sprays airflow onto the light-transmitting element to reduce the risk of impurities falling onto the second surface, while the wiping component further cleans impurities from the second surface, achieving a dual-cleaning effect. This improves the cleaning efficiency and effectiveness of the light-transmitting element, allowing the image acquisition device to acquire more accurate battery images through it.

[0007] In some embodiments, the wiping assembly includes a driving member and a wiping member connected together. The wiping member is located on the second surface, and the driving member is used to drive the wiping member to move on the second surface. Thus, the driving member drives the wiping member to move on the second surface, enabling further cleaning of impurities and other contaminants from the second surface via the wiping member. This achieves a dual-cleaning effect, improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element, thereby facilitating the image acquisition device to acquire more accurate battery images through the light-transmitting element.

[0008] In some embodiments, the wiping member includes a pressure plate and a wiping component. The pressure plate and the drive component are fixedly connected, and the wiping component is connected to the pressure plate. The wiping component is at least partially located between the pressure plate and the second surface. Thus, the connection between the pressure plate, the drive component, and the wiping component, with the wiping component at least partially located between the pressure plate and the second surface, allows the wiping component to directly contact the second surface. The drive component can drive the pressure plate to move the wiping component on the second surface, thereby reducing impurities and dust on the second surface and improving the cleaning effect on the light-transmitting element.

[0009] In some embodiments, the wiping component moves and wipes along a first direction. The wiping component includes a wiping part and two fixing parts. The wiping part is located between the pressure plate and the outer surface. Along the first direction, the two fixing parts are respectively located on both sides of the wiping part, and the fixing parts are fixed to the side of the pressure plate opposite to the wiping part. The wiping component also includes a fixing plate, which is used to fix the two fixing parts to the pressure plate. Thus, the fixing plate is used to fix the two fixing parts to the pressure plate, enhancing the fixing effect between the wiping component and the fixing parts. At the same time, it can also make the fixing plate avoid the light-transmitting element, reducing the impact of the fixing plate on the wiping part wiping the light-transmitting element. Furthermore, since the two fixing parts are connected on both sides of the wiping part in the first direction, it can also improve the wear caused by the light-transmitting element on the wiping part during movement.

[0010] In some embodiments, the number of wiping components is two, and the two wiping components are spaced apart in a direction perpendicular to the moving direction of the wiping component. Each of the two wiping components is connected to the pressure plate, and the driving member is connected to the pressure plate at a position between the two wiping components. Thus, the connection of the two wiping components to the pressure plate increases the wiping area of ​​the wiping components, while the connection of the driving member to the pressure plate at the position between the two wiping components allows for synchronized wiping actions of the two wiping components, improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element.

[0011] In some embodiments, the pressure plate is toothed on the side facing away from the light-transmitting element. This toothed shape on the side of the pressure plate away from the light-transmitting element enhances the fixing effect between the pressure plate and the wiping part.

[0012] In some embodiments, the battery swapping mechanism includes a guide member connected to the second surface. The guide member has a guide groove extending along the direction of movement of the wiping member, and a pressure plate portion extends into the guide groove. Thus, the guide groove extending along the direction of movement of the wiping member and the pressure plate portion extending into the guide groove allow the guide member to assist the pressure plate in moving the wiping member, thereby improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element.

[0013] In some embodiments, a portion of the pressure plate located in the guide groove abuts against the top of the guide member away from the light-transmitting element. This abutment between the pressure plate in the guide groove and the top of the guide member away from the light-transmitting element increases the pressure between the wiping component and the light-transmitting element, thereby improving the cleaning effect on the light-transmitting element.

[0014] In some embodiments, there are two guide members, which are spaced apart in a direction perpendicular to the movement of the wiping member. A pressure plate is located between the two guide members and extends into the guide grooves of both guide members simultaneously. This simultaneous insertion of the pressure plate into the guide grooves of both guide members improves the stability of the wiping member during movement and further increases the pressure between the wiping member and the light-transmitting element, thereby improving the cleaning effect on the light-transmitting element.

[0015] In some embodiments, the driving component includes a drive motor and a telescopic rod, the telescopic rod being connected to both the drive motor and the wiping component. The drive motor drives the telescopic rod to extend and retract, thereby moving the wiping component on the second surface. Thus, by using a drive motor to drive the telescopic rod to extend and retract, thereby moving the wiping component on the second surface, the movement of the wiping component can be simplified, work efficiency improved, and production costs reduced.

[0016] In some embodiments, the battery swapping mechanism includes a protective housing, the image acquisition device is disposed within the protective housing, and the first surface of the light-transmitting element is disposed within the protective housing. Thus, by placing the image acquisition device within the protective housing, the protective housing provides good protection for the image acquisition device, while also facilitating the installation and fixing of the light-transmitting element.

[0017] In some embodiments, the air source assembly includes at least one air source sub-assembly, which includes a first fan and an air knife, wherein the air inlet of the first fan and the air inlet of the air knife both face the second surface. Thus, with both the air inlet of the first fan and the air knife facing the second surface, the combined action of the first fan and the air knife effectively cleans impurities from the outer surface, improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element.

[0018] In some embodiments, the air source sub-assembly further includes a fan bracket, which is connected to a protective housing for mounting the image acquisition device. The first fan and the fan bracket are rotatably connected. This rotatable connection allows the first fan to rotate relative to the fan bracket, adjusting the angle between the air vent of the first fan and the outer surface, thereby further improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element.

[0019] In some embodiments, the fan bracket includes two first fixing parts and an intermediate connecting part. The two first fixing parts are spaced apart, and the intermediate connecting part connects the two first fixing parts and the protective cover. The first fan includes a fan rotating part located between the two first fixing parts and rotatably connected to the two first fixing parts. Thus, the intermediate connecting part connects the two first fixing parts and the protective cover, and the fan rotating part is rotatably connected to the two first fixing parts, simplifying the fan bracket while enhancing the fixing effect between the fan bracket and the protective cover, and between the fan bracket and the fan rotating part.

[0020] In some embodiments, the air source sub-assembly includes two locking members. Each of the first fixing parts has a strip-shaped hole, and the fan rotating part has multiple locking holes. The strip-shaped hole of each first fixing part corresponds to at least one locking hole, and one locking member passes through the strip-shaped hole and the corresponding locking hole of one first fixing part. Thus, the strip-shaped hole of each first fixing part corresponds to at least one locking hole, and one locking member passes through the strip-shaped hole and the corresponding locking hole of one first fixing part to facilitate adjusting the angle between the air vent of the first fan and the outer surface, and to fix the fan rotating part and the first fixing part after the angle adjustment is completed.

[0021] In some embodiments, the air source sub-assembly includes an air knife bracket, which is connected to a protective housing for mounting the image acquisition device. The air knife and the air knife bracket are slidably connected. This slidable connection between the air knife and the air knife bracket facilitates adjustment of the relative position between the air knife's vent and the outer surface, further improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element.

[0022] In some embodiments, the air knife bracket includes a third fixing part and a fourth fixing part connected to each other. The third fixing part is fixedly connected to the protective cover. One of the fourth fixing part and the air knife bracket is provided with a strip-shaped sliding hole, and the other is provided with a sliding member. The sliding member is engaged in the strip-shaped sliding hole, and the fourth fixing part and the air knife bracket move in the direction extending from the strip-shaped sliding hole via the sliding member. Thus, the fourth fixing part and the air knife bracket move in the direction extending from the strip-shaped sliding hole via the sliding member, enabling a simple structure to fix the air knife to the air knife bracket. Furthermore, it allows the air knife to move relative to the outer surface in a specific direction, improving both the cleaning efficiency and the cleaning effect on the light-transmitting element.

[0023] In some embodiments, the number of air source sub-assemblies is two sets, and the two air source sub-assemblies are spaced apart in a direction perpendicular to the moving direction of the wiping member. Therefore, by providing two sets of air source sub-assemblies, the cleaning efficiency and cleaning effect on the light-transmitting element can be further improved.

[0024] In some embodiments, the air source assembly includes a second fan, which generates an airflow parallel to or gradually moving away from the second surface on the side of the second surface away from the image acquisition device. Thus, by generating an airflow parallel to or gradually moving away from the second surface on the side of the second surface away from the image acquisition device, the second fan can improve the direct entry of impurities and other contaminants onto the second surface, thereby reducing impurities on the second surface and improving the cleaning effect on the light-transmitting element.

[0025] In some embodiments, there are two air source sub-assemblies, which are spaced apart in a direction perpendicular to the moving direction of the wiping element. At least a portion of the projection of the second fan's vent onto the reference plane lies between the projections of the two first fans of the two air source sub-assemblies onto the reference plane, wherein the reference plane and the second surface are perpendicular to each other. Therefore, the projection of at least a portion of the second fan's vent onto the reference plane lies between the projections of the two first fans of the two air source sub-assemblies onto the reference plane, allowing the second fan to better cooperate with the two first fans to reduce impurities on the outer surface and improve the cleaning effect on the light-transmitting element.

[0026] In some embodiments, the battery swapping mechanism includes a water receiving tray located on the side of the wiping member opposite to the light-transmitting element. The water receiving tray has at least one clearance opening that partially avoids the second surface in a direction perpendicular to the second surface. Therefore, by having the clearance opening partially avoid the second surface in a direction perpendicular to the second surface, the risk of water stains directly contacting the second surface can be reduced, and the impact of the water receiving tray on the image acquisition device acquiring battery images through the light-transmitting element can also be reduced.

[0027] In some embodiments, the water receiving tray is provided with a water receiving groove, the opening of which faces away from the light-transmitting element, and a water outlet is provided on the side wall of the water receiving groove. Thus, the water receiving tray with the water receiving groove, the opening of which faces away from the light-transmitting element, and the water outlet on the side wall of the water receiving groove, can temporarily store water stains, further reducing the risk of water stains directly contacting the second surface. Simultaneously, the water stains can be guided to the water outlet and discharged from the water receiving groove via the receiving groove.

[0028] In some embodiments, the air source assembly includes a second fan, the water outlet is located in the path of the airflow generated by the second fan, and is located on the side of the water receiving tray away from the second fan. Thus, the water outlet being located in the path of the airflow generated by the second fan and on the side of the water receiving tray away from the second fan allows the second fan to assist in guiding water stains in the receiving tank to the water outlet and discharge them from the receiving tank, improving the efficiency of water stain discharge.

[0029] In some embodiments, the battery swapping mechanism includes a support base, and the image acquisition device, the wiping assembly, and the air source assembly are disposed on the support base. Thus, the support base simultaneously supports the image acquisition device, the wiping assembly, and the air source assembly, facilitating their relative fixation and improving the cleaning efficiency of the light-transmitting elements.

[0030] To address the aforementioned issues, this application provides a battery swapping station, which includes the battery swapping mechanism described above. Attached Figure Description

[0050] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0051] Batteries, as discussed in this field, can be categorized into primary batteries and rechargeable batteries based on whether they are rechargeable. Primary batteries, also known as "use-and-discard" batteries or galvanic cells, cannot be recharged after their charge is depleted and must be discarded. Rechargeable batteries, also called secondary batteries or rechargeable batteries, differ from primary batteries in their manufacturing materials and processes. Their advantage lies in their ability to be cycled multiple times after charging, and their output current capacity is higher than most primary batteries. Common types of rechargeable batteries include lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries. Lithium-ion batteries are lightweight, have a large capacity (1.5 to 2 times that of a nickel-metal hydride battery of the same weight), no memory effect, and a very low self-discharge rate, thus enjoying widespread use despite their relatively high price. Lithium-ion batteries are also widely used in pure electric vehicles and hybrid vehicles. While the capacity of lithium-ion batteries used in these applications is relatively lower, they offer a larger output and charging current, and a longer lifespan, but at a higher cost.

[0052] The batteries described in the embodiments of this application refer to rechargeable batteries or disposable batteries. The embodiments disclosed in this application will be described below primarily using lithium-ion batteries as an example. It should be understood that the embodiments disclosed in this application are applicable to any other suitable type of rechargeable battery. The batteries mentioned in the embodiments disclosed in this application can be directly or indirectly used in suitable devices to power those devices.

[0053] Electrical devices can include, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc. Electrical devices can include batteries, which provide electrical power to achieve their functions.

[0054] Taking an electric vehicle as an example, the electric vehicle may include a battery. The electric vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The battery is internally located within the electric vehicle, and can be located at the bottom, front, or rear of the vehicle. The battery can be used to power the electric vehicle; for example, the battery can serve as the operating power source for the electric vehicle. The electric vehicle may also include a controller and a motor. The controller is used to control the battery's power supply to the motor, for example, to meet the power needs of the electric vehicle during starting, navigation, and driving.

[0055] Currently, energy replenishment for electric vehicles mainly includes charging at charging stations and battery swapping at battery swapping stations. Charging at charging stations has drawbacks such as low charging efficiency, high space requirements, high battery maintenance costs, and reduced battery lifespan. Battery swapping, on the other hand, significantly improves energy replenishment efficiency, requires less space, and avoids the adverse effects on battery lifespan caused by charging in suboptimal environments.

[0056] Directly replacing the batteries of new energy vehicles has become the mainstream development direction for energy replenishment. However, during the battery swapping process, an image acquisition device is needed to obtain the battery's status information. This information can then assist in performing the swapping operation. However, the image acquisition device is easily affected by impurities during battery image acquisition, making it difficult to accurately obtain battery information and ensuring the smooth progress of the swapping operation.

[0057] To address the technical problems existing in related technologies, this application provides a battery swapping mechanism and a battery swapping station. The battery swapping station may include a battery swapping mechanism according to any of the following embodiments. The battery swapping mechanism includes an image acquisition device, which acquires battery images through a light-transmitting element. Before acquiring the battery image, the second surface of the light-transmitting element can be cleaned by the cooperation of an air source component and a wiping component, thereby improving the cleaning efficiency of the light-transmitting element and enhancing the cleaning effect on the light-transmitting element, so that the image acquisition device can acquire more accurate battery images through the light-transmitting element.

[0058] Specifically, see Figure 1 and Figure 2 , Figure 1 This is a first structural schematic diagram of a battery swapping mechanism according to one or more embodiments of this application. Figure 2 yes Figure 1 The diagram shows the structure of the battery swapping mechanism after removing some components.

[0059] The battery swapping mechanism 10 is used for removing and / or installing batteries in a vehicle. The battery swapping mechanism 10 includes an image acquisition device 110, a light-transmitting element 200, and a cleaning assembly. The image acquisition device 110 is mainly used to acquire battery images; for example, the image acquisition device 110 may include, but is not limited to, an RGV camera, a DSLR camera, or a mirrorless camera. The light-transmitting element 200 is located in the optical path of the image acquisition device 110. The light-transmitting element 200 includes a first surface 220 and a second surface 210. The first surface 220 of the light-transmitting element 200 faces the image acquisition device 110, and the second surface 210 faces the vehicle. The cleaning assembly includes an air source assembly 300 and a wiping assembly 400. The air source assembly 300 is used to spray airflow onto the light-transmitting element 200; the wiping assembly 400 is used to wipe the second surface 210 of the light-transmitting element 200.

[0060] The light-transmitting element 200 can be transparent glass. It can serve as the lens of the image acquisition device 110, or it can be independent of the image acquisition device 110. The light-transmitting element 200 has a light-transmitting function and is located in the optical path of the image acquisition device 110. The image acquisition device 110 can acquire battery images through the light-transmitting element 200. For example, when a battery swapping operation is required for an electric vehicle, the electric vehicle can be first raised, and then the battery swapping mechanism 10 can be moved below the electric vehicle. The image acquisition device 110 can then acquire battery images through the light-transmitting element 200. The battery can include a battery assembly, which can include multiple battery cells. These multiple battery cells can be connected in series, parallel, or a hybrid connection. A hybrid connection means that multiple battery cells are connected in both series and parallel. Multiple battery cells can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple battery cells can be housed in a battery box. Alternatively, the battery device can be composed of multiple battery cells first connected in series, parallel, or in a mixed manner to form a battery module, and then multiple battery modules can be connected in series, parallel, or in a mixed manner to form an entire assembly, which can be housed in a battery box.

[0061] During or before the image acquisition operation of the image acquisition device 110, impurities may adhere to the second surface 210 of the light-transmitting element 200, making it difficult for the image acquisition device 110 to acquire a clear battery image through the light-transmitting element 200. In this embodiment, the air source component 300 can blow or inhale air toward the second surface 210 of the light-transmitting element 200 to change the airflow on the second surface 210, thereby cleaning impurities on the second surface 210. The wiping component 400 can move on the second surface 210 to clean impurities on the second surface 210. In some embodiments, the wiping component 400 can move on the second surface 210 while the air source component 300 changes the airflow on the second surface 210. Alternatively, the air source component 300 can first change the airflow on the second surface 210 to initially clean the second surface 210, and then the wiping component 400 can move on the second surface 210. Alternatively, the wiping component 400 can be moved on the second surface 210 to initially clean the second surface 210, and then the air source component 300 can be used to change the airflow on the second surface 210.

[0062] Through the above embodiments, the air source component 300 is used to spray airflow onto the light-transmitting element 200, thereby reducing the risk of impurities falling into the second surface 210. At the same time, the wiping component 400 is used to wipe the second surface 210 of the light-transmitting element 200, which can further clean impurities on the second surface 210, thereby achieving the effect of dual cleaning methods, improving the cleaning efficiency of the light-transmitting element 200, and improving the cleaning effect of the light-transmitting element 200, so that the image acquisition device 110 can acquire more accurate battery images through the light-transmitting element 200.

[0063] In some embodiments, the battery swapping mechanism 10 includes a protective housing 100, an image acquisition device 110 disposed within the protective housing 100, and a first surface 220 of a light-transmitting element 200 disposed within the protective housing 100. An air source assembly 300 and a wiping assembly 400 can be fixedly connected to the protective housing 100. The protective housing 100 can be recessed to form a receiving space, within which the image acquisition device 110 is fixed. The light-transmitting element 200 can be fixed to the protective housing 100. For example, the light-transmitting element 200 can be positioned on the upper side of the protective housing 100 in the direction of gravity. When the protective housing 100 is recessed to form a receiving space, the light-transmitting element 200 can be supported at the opening of the recess, thus sealing the receiving space. Therefore, the image acquisition device 110, disposed within the protective housing 100, provides good protection for the image acquisition device 110 and facilitates the installation and fixing of the light-transmitting element 200.

[0064] In some embodiments, the wiping assembly 400 includes a drive member 410 and a wiping member 420, which are connected. The wiping member 420 is located on the second surface 210, and the drive member 410 is used to drive the wiping member 420 to move on the second surface 210. The wiping member 420 can be placed on the second surface 210 and can be a soft body. The drive member 410 can be connected to the protective cover 100 and is connected to the wiping member 420. The drive member 410 can be used to drive the movement of the wiping member 420, thereby moving the wiping member 420 on the second surface 210 and cleaning impurities on the second surface 210. Therefore, the driving member 410 is used to drive the wiping member 420 to move on the second surface 210, which can further clean the impurities on the second surface 210 through the wiping member 420, thereby achieving the effect of dual cleaning mode, improving the cleaning efficiency of the light-transmitting element 200, and improving the cleaning effect on the light-transmitting element 200, so that the image acquisition device 110 can acquire more accurate battery images through the light-transmitting element 200.

[0065] Combination Figure 3 , Figure 3 yes Figure 2An enlarged schematic diagram of the first structure of the battery swapping mechanism 10 shown.

[0066] The wiping component 420 includes a pressure plate 421 and a wiping member 422. The pressure plate 421 and the driving member 410 are fixedly connected. The wiping member 422 is connected to the pressure plate 421 and is at least partially located between the pressure plate 421 and the second surface 210. The wiping member 422 may be, but is not limited to, a component such as wool felt that has a good cleaning effect and causes less damage to the light-transmitting element 200. The wiping member 422 is at least partially pressed by the pressure plate 421 onto the second surface 210 so that the wiping member 422 and the second surface 210 are in direct contact. The pressure plate 421 may be flat and is fixedly connected to the driving member 410. The driving member 410 can drive the pressure plate 421 to move, thereby causing the wiping member 422 to move on the second surface 210, thereby reducing impurities and dust on the second surface 210 and improving the cleaning effect on the light-transmitting element 200.

[0067] Furthermore, the wiping component 422 moves and wipes along a first direction. The wiping component 422 includes a wiping portion 4221 and two fixing portions 4222. The wiping portion 4221 is located between the pressure plate 421 and the second surface 210. Along the first direction, the two fixing portions 4222 are respectively located on both sides of the wiping portion 4221, and the fixing portions 4222 are fixed to the side of the pressure plate 421 away from the wiping portion 4221. The wiping component 420 also includes a fixing plate 430, which is used to fix the two fixing portions 4222 to the pressure plate 421. The wiping component 422 may be a soft body. The wiping component 422 may cover part of the pressure plate 421, wherein the part covering the pressure plate 421 and the second surface 210 can serve as the wiping portion 4221, and the parts located on both sides of the wiping portion 4221 at least partially cover the side of the pressure plate 421 away from the wiping portion 4221 as fixing portions 4222. The first direction can be a straight line. Two fixing parts 4222 are connected on both sides of the two fixing parts 4222 in the direction of movement of the wiping member 420, which can improve the wear caused by the light-transmitting element 200 to the wiping member 4221 during the movement of the wiping member 4221. The fixing plate 430 can be plate-shaped. The fixing plate 430 can press the fixing parts 4222 onto the pressure plate 421. The fixing plate 430 can be fixedly connected to the pressure plate 421 by fasteners such as bolts. For example, the ends of the two fixing parts 4222 away from the wiping member 4221 are spaced apart. The ends of the two fixing parts 4222 are located between the fixing plate 430 and the pressure plate 421. Fasteners such as bolts pass through the fixing parts 4222 and between the two ends to the pressure plate 421, so that the pressure plate 421 and the fixing parts 4222 can be fixedly connected by avoiding the wiping member 4221 with bolts.

[0068] Combination Figure 4 , Figure 4 yes Figure 2An enlarged schematic diagram of the second structure of the battery swapping mechanism 10 shown.

[0069] The battery swapping mechanism 10 includes a guide member 500 connected to the second surface 210. The guide member 500 has a guide groove 510 extending along the direction of movement of the wiping member 420. A pressure plate 421 partially extends into the guide groove 510. The guide member 500 can be located in the edge region of the second surface 210. The guide member 500 can be elongated. The shape of the guide groove 510 can correspond to the shape of the edge of the pressure plate 421. A portion of the pressure plate 421 extends into the guide groove 510. The wiping part 4221 is spaced apart from the guide member 500. When the driving member 410 drives the pressure plate 421 to move, the guide groove 510 can guide the pressure plate 421 to move along the direction of extension of the guide groove 510, thereby improving the cleaning efficiency of the light-transmitting element 200 and improving the cleaning effect on the light-transmitting element 200.

[0070] Furthermore, the portion of the pressure plate 421 located in the guide groove 510 abuts against the top of the guide member 500 away from the light-transmitting element 200. The guide groove 510 can be a U-shaped groove. When the pressure plate 421 is not inserted into the guide groove 510, the wiping part 4221 is in an uncompressed or slightly compressed state, and the wiping part 4221 can lift the pressure plate 421, making the pressure plate 421 higher than the guide groove 510 in the horizontal direction. When the pressure plate 421 is inserted into the guide groove 510, the pressure plate 421 abuts against the top of the guide member 500 away from the light-transmitting element 200, causing the wiping part 4221 to be compressed by the pressure plate 421, increasing the squeezing force between the wiping part 422 and the light-transmitting element 200, thereby improving the cleaning effect on the light-transmitting element 200.

[0071] Furthermore, there are two guide members 500, which are spaced apart in a direction perpendicular to the movement of the wiping member 420. A pressure plate 421 is located between the two guide members 500 and extends into the guide grooves 510 of both guide members 500. The pressure plate 421, located between the two guide members 500 and extending into the guide grooves 510, can improve the stability of the wiping member 422 during movement and further increase the pressure between the wiping member 422 and the light-transmitting element 200, thereby improving the cleaning effect on the light-transmitting element 200.

[0072] Furthermore, there are two wiping components 422, which are spaced apart in a direction perpendicular to the moving direction of the wiping member 420. Each of the two wiping components 422 is connected to the pressure plate 421, and the driving member 410 is connected to the pressure plate 421 at a position between the two wiping components 422. In this embodiment, the pressure plate 421 may be convex in shape, with the two wiping components 422 connected to both sides of the pressure plate 421, and the driving member 410 connected to the middle protruding portion of the pressure plate 421. By connecting the two wiping components 422 to the pressure plate 421, the wiping area of ​​the wiping components 422 can be increased. Simultaneously, the driving member 410, connected to the pressure plate 421 at a position between the two wiping components 422, enables the wiping actions of the two wiping components 422 to be synchronized, improving the cleaning efficiency of the light-transmitting element 200 and enhancing the cleaning effect on the light-transmitting element 200.

[0073] See Figure 5 , Figure 5 This is a schematic diagram of the structure of the pressure plate 421 according to one or more embodiments of this application.

[0074] The pressure plate 421 is toothed on the side opposite to the light-transmitting element 200. In this embodiment, the surface of the pressure plate 421 has a toothed structure with intermittent concave and convex surfaces. The pressure plate 421 is pressed against the wiping part 4221 by the toothed structure. The wiping part 4221 may be, but is not limited to, a component such as wool felt that has a good cleaning effect and causes less damage to the light-transmitting element 200. The wiping part 4221 may be partially embedded in the toothed structure, which can enhance the fixing effect between the pressure plate 421 and the wiping part 4221, thereby improving the cleaning effect on the light-transmitting element 200.

[0075] See further Figures 1 to 4 The driving component 410 includes a drive motor 411 and a telescopic rod 412. The telescopic rod 412 is connected to both the drive motor 411 and the wiping component 420. The drive motor 411 drives the telescopic rod 412 to extend and retract, thereby moving the wiping component 420 on the second surface 210. The drive motor 411 can be located on the outside of the second surface 210 and can be mounted on a mounting base, which can be fixed to the protective cover 100. The telescopic rod 412 can be connected to the output end of the drive motor 411, and the other end of the telescopic rod 412 can be connected to the pressure plate 421 of the wiping component 420. The drive motor 411 can drive the telescopic rod 412 to extend and retract along the axial direction of the telescopic rod 412, thereby moving the telescopic rod 412 on the second surface 210, simplifying the movement of the wiping component 420, improving work efficiency, and reducing production costs.

[0076] In some embodiments, the air source assembly 300 includes at least one air source sub-assembly 310, which includes a first fan 311 and an air knife 312. The air inlets of the first fan 311 and the air knife 312 both face the second surface 210. The first fan 311 can be fixedly connected to the protective cover 100. The first fan 311 can be, but is not limited to, a suction fan or a blower fan. When it is necessary to clean impurities on the second surface 210, the air inlet of the first fan 311 can be directed towards the second surface 210, thereby changing the airflow on the second surface 210. The air knife 312 can be fixedly connected to the protective cover 100 and spaced apart from the first fan 311. The air knife 312 can have an air inlet, which can be connected to a compressed air supply device. The air knife 312 can receive compressed air through the air inlet, and then output a strong airflow to the second surface 210 through the air inlet of the air knife 312, thereby changing the airflow on the second surface 210. Thus, the first fan 311 and the air knife 312 work together to effectively clean the impurities on the second surface 210, improve the cleaning efficiency of the light-transmitting element 200, and improve the cleaning effect on the light-transmitting element 200.

[0077] Furthermore, combined Figure 6 , Figure 6 This is a schematic diagram of the structure of the first fan 311 and the fan bracket 313 according to one or more embodiments of this application.

[0078] The air source component 310 includes a fan bracket 313, which is connected to the protective cover 100. A first fan 311 is rotatably connected to the fan bracket 313. The fan bracket 313 is fixedly connected to the protective cover 100, and the rotatable connection between the first fan 311 and the fan bracket 313 allows adjustment of the angle between the vent of the first fan 311 and the second surface 210, thereby further improving the cleaning efficiency of the light-transmitting element 200 and enhancing the cleaning effect on the light-transmitting element 200.

[0079] Furthermore, the fan bracket 313 includes two first fixing parts 3131 and an intermediate connecting part 3132. The two first fixing parts 3131 are spaced apart, and the intermediate connecting part 3132 connects the two first fixing parts 3131 and the protective cover 100. The first fan 311 includes a fan rotating part 3111, which is located between the two first fixing parts 3131 and is rotatably connected to the two first fixing parts 3131. The two first fixing parts 3131 can be connected to the same side of the intermediate connecting part 3132, and the two first fixing parts 3131 and the intermediate connecting part 3132 can together form a U-shaped structure. The side of the intermediate connecting part 3132 facing away from the two first fixing parts 3131 can be used for fixed connection with the protective cover 100. The fan rotating part 3111 can be located between the two first fixed parts 3131. The fan rotating part 3111 can be rotatably connected to the two first fixed parts 3131 and can rotate relative to the two first fixed parts 3131 to adjust the angle between the first fan 311 and the second surface 210. The fan rotating part 3111 can be spaced apart from the intermediate connecting part 3132 so that the intermediate connecting part 3132 can be avoided during the rotation of the fan rotating part 3111 relative to the two first fixed parts 3131. This simplifies the fan bracket 313 and enhances the fixing effect between the fan bracket 313 and the protective cover 100, and between the fan bracket 313 and the fan rotating part 3111.

[0080] Furthermore, the air source sub-assembly 310 includes two locking members 314. Each first fixing part 3131 is provided with a strip-shaped hole 3133, and the fan rotating part 3111 is provided with multiple locking holes 3134. The strip-shaped hole 3133 of each first fixing part 3131 corresponds to at least one locking hole 3134. A locking member 314 passes through the strip-shaped hole 3133 and the corresponding locking hole 3134 of a first fixing part 3131. The fan rotating part 3111 and the two first fixing parts 3131 may be provided with corresponding shaft holes. The shaft holes can be used to insert a shaft so that the fan rotating part 3111 can rotate relative to the two first fixing parts 3131 around the shaft. The strip-shaped hole 3133 can be an oblong hole, and the strip-shaped hole 3133 can be arranged in a ring. The center of the ring-shaped strip-shaped hole 3133 can be located at the shaft hole. Each first fixing part 3131 is provided with a strip-shaped hole 3133. The fan rotating part 3111 is provided with a plurality of locking holes 3134 on one side corresponding to each of the first fixing parts 3131. The plurality of locking holes 3134 on each side can be arranged along the extension direction of the strip hole 3133 of the corresponding first fixing part 3131. For example, the plurality of locking holes 3134 on each side can be arranged in a ring. During the process of the fan rotating part 3111 rotating around the axis relative to the two first fixing parts 3131, at least one locking hole 3134 on each side is located in the strip hole 3133 of the corresponding first fixing part 3131, so that each locking member 314 can be inserted into the corresponding strip hole 3133 and locking hole 3134 to fix the first fixing part 3131 and the fan rotating part 3111. This makes it easy to adjust the angle between the air vent of the first fan 311 and the second surface 210, and to fix the fan rotating part 3111 and the first fixing part 3131 after the angle adjustment is completed.

[0081] Combination Figure 7 , Figure 7 This is a schematic diagram of the structure of the air knife 312 and the air knife support 315 according to one or more embodiments of this application.

[0082] The air source component 310 includes an air knife bracket 315, which is connected to the protective housing 100. An air knife 312 is slidably connected to the air knife bracket 315. One end of the air knife bracket 315 is detachably connected to the protective housing 100, and the other end is slidably connected to the air knife 312. For example, one of the air knife bracket 315 and the air knife 312 may be provided with a slide rail, and the air knife 312 can be slidably connected to the air knife bracket 315 via the slide rail and the slider. Thus, the slidable connection between the air knife 312 and the air knife bracket 315 facilitates adjustment of the relative position between the air vent of the air knife 312 and the second surface 210, further improving the cleaning efficiency of the light-transmitting element 200 and enhancing the cleaning effect on the light-transmitting element 200.

[0083] Furthermore, the air knife bracket 315 includes a third fixing part 3151 and a fourth fixing part 3152 connected to each other. The third fixing part 3151 is fixedly connected to the protective cover 100. One of the fourth fixing part 3152 and the air knife bracket 315 is provided with a strip-shaped sliding hole 3153, and the other is provided with a sliding member. The sliding member is engaged in the strip-shaped sliding hole 3153. The fourth fixing part 3152 and the air knife bracket 315 can move in the direction extending from the strip-shaped sliding hole 3153 through the sliding member. The third fixing part 3151 can be bent and connected to the fourth fixing part 3152. The third fixing part 3151 is detachably connected to the side wall of the protective cover 100. The fourth fixing part 3152 can be located above the light-transmitting element 200, and the air knife bracket 315 can be slidably connected to the fourth fixing part 3152. The strip-shaped sliding hole 3153 can be straight, and the sliding member can be convex. The size of the sliding member can match the strip-shaped sliding hole 3153 so that the sliding member can be engaged in the strip-shaped sliding hole 3153 and can move back and forth in the direction of extension of the strip-shaped sliding hole 3153. The strip-shaped sliding hole 3153 can be provided on the fourth fixing part 3152, and the sliding member can be provided on the air knife 312. Alternatively, the sliding member can be provided on the fourth fixing part 3152, and the strip-shaped sliding hole 3153 can be provided on the air knife 312. Alternatively, sliding members and strip-shaped sliding holes 3153 spaced apart can be simultaneously formed on the air knife 312, and sliding members and strip-shaped sliding holes 3153 spaced apart can also be simultaneously formed on the fourth fixing part 3152. The sliding members on the air knife 312 are engaged in the strip-shaped sliding holes 3153 of the fourth fixing part 3152, and the sliding members on the fourth fixing part 3152 are engaged in the strip-shaped sliding holes 3153 of the air knife 312. In this way, the air knife 312 can be fixedly connected to the air knife bracket 315 with a simple structure, and the air knife 312 can also move relative to the second surface 210 in a specific direction, which can improve the cleaning efficiency of the light-transmitting element 200 and improve the cleaning effect on the light-transmitting element 200.

[0084] In some embodiments, the number of air source sub-assemblies 310 is two sets, and the two sets of air source sub-assemblies 310 are spaced apart in a direction perpendicular to the moving direction of the wiping member 420. The structures of the two sets of air source sub-assemblies 310 can be the same or different. For example, the first fan 311 of the two sets of air source sub-assemblies 310 can be the same, but the size of the air blade 312 can be different. For example, the length of one air blade 312 can be greater than the length of the other air blade 312. The spaced arrangement of the two sets of air source sub-assemblies 310 in a direction perpendicular to the moving direction of the wiping member 420 allows at least part of the wiping member 420 to move between the two sets of air source sub-assemblies 310. Correspondingly, the image acquisition device 110 can acquire battery images through the light-transmitting element 200 between the two sets of air source sub-assemblies 310, thereby reducing the interference of the two sets of air source sub-assemblies 310 and the wiping member 420 on the image acquisition device 110. Therefore, by setting up two sets of air source sub-components 310, the cleaning efficiency of the light-transmitting element 200 can be further improved, as well as the cleaning effect of the light-transmitting element 200 can be improved.

[0085] See Figure 8 , Figure 8 This is a second structural schematic diagram of the battery swapping mechanism 10 according to one or more embodiments of this application.

[0086] The air source assembly 300 includes a second fan 316, which generates an airflow parallel to or gradually moving away from the second surface 210 on the side of the second surface 210 away from the image acquisition device 110. The second fan 316 can be fixedly connected to the protective housing 100 and can be located outside the light-transmitting element 200. The vent of the second fan 316 can be parallel to the second surface 210, so that the second fan 316 generates an airflow parallel to the second surface 210 on the side of the second surface 210 away from the image acquisition device 110. Alternatively, the vent of the second fan 316 can be tilted upwards relative to the second surface 210, so that the second fan 316 generates an airflow gradually moving away from the second surface 210 on the side of the second surface 210 away from the image acquisition device 110. The second fan 316 can be a suction fan or a blower, etc. In some application scenarios, when it is necessary to perform battery swapping on an electric vehicle, the electric vehicle can be lifted first, and then the battery swapping mechanism 10 can be moved under the electric vehicle. Then, the image acquisition device 110 can acquire battery images through the light-transmitting element 200. During the image acquisition process, impurities may fall from the vehicle. During this process, the second fan 316 can initially blow away the impurities during the falling process, reducing the number of impurities falling onto the light-transmitting element and improving the cleaning effect on the light-transmitting element 200.

[0087] Furthermore, there are two air source sub-assemblies 310, which are spaced apart in a direction perpendicular to the movement of the wiping member 420. The projection of at least a portion of the ventilation opening of the second fan 316 onto the reference plane is located between the projections of the two first fans 311 of the two air source sub-assemblies 310 onto the reference plane, wherein the reference plane and the second surface 210 are perpendicular to each other. The spaced arrangement of the two sets of air source sub-assemblies 310 in a direction perpendicular to the movement of the wiping member 420 allows at least a portion of the wiping member 420 to move between the two air source sub-assemblies 310. The image acquisition device 110 can acquire battery images through the light-transmitting element 200 between the two sets of air source sub-assemblies 310, thereby mitigating interference between the two sets of air source sub-assemblies 310 and the wiping member 420 on the image acquisition device 110. Correspondingly, the projection of at least a portion of the vents of the second fan 316 onto the reference plane is located between the projections of the two first fans 311 of the two air source components 310 onto the reference plane, which enables the second fan 316 to better cooperate with the two first fans 311 to reduce impurities on the second surface 210 and improve the cleaning effect on the light-transmitting element 200.

[0088] In some embodiments, the battery swapping mechanism 10 includes a water receiving tray 600 located on the side of the wiping member 420 away from the light-transmitting element 200. The water receiving tray 600 has at least one clearance opening 630, which avoids a portion of the second surface 210 in a direction perpendicular to the second surface 210. The water receiving tray 600 can be fixedly connected to the wiping member 420 and can move synchronously with the wiping member 420, or the water receiving tray 600 can be fixedly connected to other components and spaced apart from the wiping member 420 to alleviate interference of the water receiving tray 600 with the movement of the wiping member 420. The clearance opening 630 can expose a portion of the second surface 210. The first fan 311 and the air knife 312 of the air source distribution assembly 310 can change the airflow on the portion of the second surface 210 exposed by the clearance opening 630. Furthermore, the image acquisition device 110 can acquire battery images through the portion of the second surface 210 exposed by the clearance opening 630. When there are two sets of air source components 300, there can be two clearance ports 630. Each clearance port 630 corresponds to one set of air source components 300. The first fan 311 and the air knife 312 of each set of air source components 300 can change the airflow of the second surface 210 through the corresponding clearance port 630. In some application scenarios, when it is necessary to perform a battery swapping operation on an electric vehicle, the electric vehicle can be lifted first, and then the battery swapping mechanism 10 can be moved to the bottom of the electric vehicle. Then, the image acquisition device 110 can acquire the battery image through the light-transmitting element 200. During the image acquisition process, impurities may fall from the vehicle. During this process, the water receiving tray 600 can receive the impurities and liquids falling during the process, reducing the total amount of liquid and impurities falling onto the light-transmitting element and improving the cleaning effect on the light-transmitting element 200. Therefore, the avoidance opening 630 avoids part of the second surface 210 in the direction perpendicular to the second surface 210, which can reduce the risk of water stains directly contacting the second surface 210 through the water receiving tray 600, and at the same time reduce the impact of the water receiving tray 600 on the image acquisition device 110 to acquire battery images through the light-transmitting element 200.

[0089] Furthermore, the water receiving tray 600 is provided with a water receiving groove 610, the opening of which faces away from the light-transmitting element 200, and a water outlet 620 is provided on the side wall of the water receiving groove 610. A vertical plate can be formed along the edge of the water receiving tray 600, and the water receiving groove 610 can be formed by surrounding the vertical plate to temporarily store water stains. The shape and position of the water outlet 620 can be set according to actual conditions. For example, the water outlet can be located on the side of the second surface 210 to guide water stains in the water receiving groove 610 to the water outlet 620 and discharge them from the water receiving groove 610, while also preventing water stains in the water receiving groove 610 from entering the second surface 210 through the water outlet.

[0090] Furthermore, the air source assembly 300 includes a second fan 316, a water outlet 620 located in the path of the airflow generated by the second fan 316, and a water receiving tray 600 located on the side away from the second fan 316. The second fan 316 can be used to generate airflow parallel to or gradually moving away from the second surface 210 on the side of the second surface 210 away from the image acquisition device 110. Figure 8 As shown, the second fan 316 is fixedly connected to the protective cover 100, and the second fan 316 is located on the oblique outer side of the second surface 210. The water receiving tray 600 is partially located above the second surface 210, and the water inlet is located on the side of the water receiving tray 600 away from the second fan 316. When the second fan 316 generates a blowing airflow, water stains in the water receiving tank 610 can be blown out of the water receiving tank 610 through the water inlet. In some other embodiments, the second fan 316 can generate a suction airflow, and the water outlet 620 can be located on the path of the airflow generated by the second fan 316 and on the side of the water receiving tray 600 close to the second fan 316. When the second fan 316 generates a suction airflow, water stains in the water receiving tank 610 can be sucked out of the water receiving tank 610 through the water inlet. Thus, the second fan 316 can assist in guiding water stains in the receiving tank to the water outlet 620 and discharge them from the water receiving tank 610, improving the water stain discharge efficiency.

[0091] See Figure 9 , Figure 9 This is a third structural schematic diagram of the battery swapping mechanism 10 according to one or more embodiments of this application.

[0092] The battery swapping mechanism 10 includes a support base 700, and an image acquisition device 110, a wiping assembly 400, and an air source assembly 300 are disposed on the support base 700. The shape of the support base 700 can be set according to actual conditions. The support base 700 may include a base plate, a middle support column, and an upper end plate. The middle support column connects the base plate and the upper end plate. The image acquisition device 110, the protective cover 100, the wiping assembly 400, and the air source assembly 300 can all be directly or indirectly fixedly connected to the upper end plate. For example, the protective cover 100 is fixedly connected to the upper end plate, and the air source assembly 300 can be fixedly connected to the protective cover 100, or the air source assembly 300 is fixedly connected to the upper end plate, or part of the air source assembly 300 is fixedly connected to the protective cover 100, and the rest is fixedly connected to the upper end plate.

The battery swapping mechanism 10 may also include pulleys, which can be connected to the base plate to allow the protective housing 100, the air source assembly 300, and the wiping assembly 400 to move synchronously via the support base 700. Thus, the support base 700 simultaneously supports the protective housing 100, the wiping assembly 400, and the air source assembly 300, facilitating their relative fixation and improving the cleaning efficiency of the light-transmitting element 200.

[0093] In summary, the air source assembly 300 is used to spray airflow onto the light-transmitting element 200, thereby reducing the risk of impurities falling into the second surface 210. At the same time, the wiping assembly 400 is used to wipe the second surface 210 of the light-transmitting element 200, which can further clean impurities on the second surface 210. This achieves the effect of dual cleaning, improves the cleaning efficiency of the light-transmitting element 200, and enhances the cleaning effect of the light-transmitting element 200, so that the image acquisition device 110 can acquire more accurate battery images through the light-transmitting element 200.
