Description

Technical Field

[0001] This utility model relates to the field of battery swapping vehicle technology, and in particular to a bottom cleaning device and a battery swapping station for battery swapping vehicles. Background Technology

[0002] The battery swapping vehicle uses a detachable battery pack as the power source for the entire vehicle, which can quickly replenish energy through battery swapping. The battery pack is installed at the bottom of the battery swapping vehicle through a lock body. When swapping batteries, the lock body needs to be unlocked, the depleted battery pack needs to be removed, and the fully charged battery pack needs to be installed at the bottom of the battery swapping vehicle. The battery swapping is then completed by locking the lock body.

[0003] In rainy or snowy weather, or on roads with poor conditions (such as standing water), water will accumulate on the bottom of the battery swapping vehicle. Due to the complex road conditions in which the battery swapping vehicle travels, dirt can easily adhere to the bottom of the vehicle. In cold weather, the water on the bottom of the battery swapping vehicle can easily freeze. The ice and dirt covering the bottom of the vehicle can cause the battery pack and / or its lock to freeze, making it difficult or impossible to unlock the lock during battery swapping. This increases the time required for battery swapping and affects the efficiency of battery swapping. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a bottom cleaning device and a battery swapping station for battery swapping vehicles, which can clean the bottom of the battery swapping vehicle to remove ice and dirt, thereby improving battery swapping efficiency.

[0005] This utility model provides a bottom cleaning device for battery swapping vehicles, applicable to battery swapping vehicles with a battery pack detachably mounted on the bottom via a lock, comprising:

[0006] The blower mechanism includes a lock body blower and a battery pack blower. The lock body blower cooperates with the lock body of the battery swapping vehicle and can output hot air to the lock body. The battery pack blower cooperates with the battery pack of the battery swapping vehicle and can output hot air to the battery pack.

[0007] The blower mechanism and the ice scraping mechanism are configured to move relative to the bottom of the battery swapping vehicle and to scrape off the ice.

[0008] In one embodiment, the blower mechanism further includes an integrated component, through which the lock body blower and the battery pack blower are connected as one unit, and a branch pipe is connected to the integrated component, the branch pipe being connected to the lock body blower and the battery pack blower.

[0009] In one embodiment, the lock body blowing component includes a first air distribution pipe and a first connecting pipe. The first air distribution pipe is connected to an air source and communicates with the first connecting pipe. Both the first air distribution pipe and the first connecting pipe include a first air outlet. The first air outlet cooperates with the lock body of the battery swapping vehicle to output hot air to the lock body.

[0010] In one embodiment, the integrated component includes an air cavity, one end of the first branch duct is connected to the integrated component and communicates with the air cavity, and the branch duct communicates with the air cavity and the first connecting duct.

[0011] In one embodiment, the ice-scraping mechanism includes a scraper and an adjusting member. The scraper is capable of contacting the ice layer on the bottom of the battery-swapping vehicle, and the scraper is mounted on the adjusting member, which is configured to adjust the height of the scraper relative to the bottom of the battery-swapping vehicle.

[0012] In one embodiment, a positioning mechanism is further included, which includes a first positioning member and a second positioning member. The first positioning member and the second positioning member are disposed opposite to each other on both sides of the blower mechanism, and the first positioning member and the second positioning member are capable of contacting both ends of the battery pack of the battery swapping vehicle.

[0013] In one embodiment, ice scrapers are installed at the front ends of the first positioning member and the second positioning member, and the ice scrapers are capable of scraping away the ice layer between the two ends of the battery pack and the bottom of the battery swapping vehicle.

[0014] In one embodiment, the positioning mechanism further includes a third positioning element capable of contacting the rear end of the battery pack of the battery swapping vehicle.

[0015] In one embodiment, the system further includes a body on which the blower mechanism and the ice scraper mechanism are mounted.

[0016] This utility model also proposes a battery swapping station, which is equipped with the aforementioned bottom cleaning device for battery swapping vehicles.

[0017] The beneficial effects of this utility model are as follows:

[0018] The blower mechanism can output hot air to the bottom of the battery swapping vehicle, which can easily melt the ice on the bottom of the vehicle. The blower on the lock body can melt the ice at the lock body, so as to facilitate the unlocking of the battery pack with the battery swapping equipment. The battery pack can be easily removed and then the fully charged battery pack can be locked to the bottom of the battery swapping vehicle. The blower on the battery pack can melt the ice at the battery pack, so as to prevent the ice from affecting the subsequent transportation, charging and swapping of the battery pack, which helps to ensure the efficiency and quality of battery swapping.

[0019] The ice-scraping mechanism, in conjunction with the blower mechanism, can scrape away the ice layer on the bottom of the battery swapping vehicle, which helps to ensure de-icing efficiency.

[0032] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0036] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0037] The battery swapping vehicle bottom cleaning device proposed in this utility model is applied to battery swapping vehicles that require battery swapping. The battery pack is detachably installed on the bottom of the battery swapping vehicle via a lock body. When swapping batteries, the lock body needs to be unlocked, the depleted battery pack needs to be removed, and the fully charged battery pack needs to be installed on the bottom of the battery swapping vehicle. The battery swapping is then completed by locking the lock body.

[0038] In rainy or snowy weather, or on roads with poor conditions (such as standing water), water will accumulate on the bottom of the battery swapping vehicle. Due to the complex road conditions on which the vehicle travels, dirt can easily adhere to its bottom. In cold weather, the water on the bottom of the vehicle can easily freeze. The ice and dirt covering the bottom of the vehicle can cause the battery pack and / or lock to freeze, making it difficult or impossible to unlock the lock during battery swapping. This increases the time required for battery swapping and affects the efficiency of the swapping process.

[0039] If the battery swapping equipment cannot be precisely aligned with the lock body due to ice and dirt, it can easily lead to damage to the lock body, causing economic losses to the user, and in severe cases, accidents, resulting in poor safety. The presence of ice and dirt will cause the bottom of the battery pack to be uneven, making it easy to shake or fall during transportation, affecting the delivery efficiency and battery swapping quality, and in severe cases, damaging the battery pack. Furthermore, if the ice melts during transportation, charging, and battery swapping, the dripping water can easily contaminate other equipment and create safety hazards. Therefore, it is necessary to clean the bottom of the battery swapping vehicle.

[0040] Combination Figure 1 and Figure 3 This utility model proposes a bottom cleaning device for battery swapping vehicles, applicable to battery swapping vehicles with battery packs detachably mounted on the bottom via a lock, comprising:

[0041] The blower mechanism 100 includes a lock body blower 110 and a battery pack blower 120. The lock body blower 110 cooperates with the lock body of the battery swapping vehicle and can output hot air to the lock body. The battery pack blower 120 cooperates with the battery pack of the battery swapping vehicle and can output hot air to the battery pack.

[0042] The ice scraping mechanism 200 is able to contact the ice layer on the bottom of the battery swapping vehicle to scrape off the ice layer. The blower mechanism 100 and the ice scraping mechanism 200 are configured to be able to move relative to the bottom of the battery swapping vehicle.

[0043] The blower mechanism 100 can output hot air to the bottom of the battery swapping vehicle, which can easily melt the ice layer on the bottom of the battery swapping vehicle. The lock body blower 110 can melt the ice layer at the lock body, so as to facilitate the unlocking of the battery pack with the battery swapping equipment. The battery pack can be easily removed and then the fully charged battery pack can be locked to the bottom of the battery swapping vehicle. The battery pack blower 120 can melt the ice layer at the battery pack, so as to prevent the ice layer from affecting the subsequent transportation, charging and swapping of the battery pack, which helps to ensure the efficiency and quality of battery swapping.

[0044] The ice scraping mechanism 200 can work with the blower mechanism 100 to scrape off the ice layer on the bottom of the battery swapping vehicle, which helps to ensure de-icing efficiency. In particular, when there is dirt on the bottom of the battery swapping vehicle, the dirt can be removed during the de-icing process, preventing dirt from affecting the locking and unlocking of the lock body and / or affecting the transportation and charging of the battery pack, thus ensuring the normal operation of the battery swapping.

[0045] In one embodiment, reference is made to Figure 1 The coordinate system in the diagram refers to the X, Y, and Z directions, which are based on the vehicle coordinate system. The vehicle coordinate system is a special moving coordinate system used to describe the motion of a car. The origin of this coordinate system coincides with the center of mass of the vehicle. When the vehicle is stationary on a level road, the X direction of this coordinate system refers to the direction parallel to the direction of the car's travel, the Y direction refers to the width direction of the car, and the Z direction refers to the height direction of the car.

[0046] In use, the cleaning device of this utility model moves along the Y-axis of the battery swapping vehicle from between the front and rear wheels to the bottom of the vehicle, and then moves out from the bottom of the vehicle along the Y-axis, repeating this motion. The blowing mechanism 100 melts the ice layer, and the reciprocating motion of the ice scraping mechanism 200 removes the ice and dirt. Since the entire cleaning device moves along the Y-axis of the battery swapping vehicle, the end of the cleaning device that first enters the bottom of the vehicle in the Y-axis is defined as the front end, and the opposite end as the rear end.

[0047] In one embodiment, combined with Figure 1 and Figure 3 The lock body blowing component 110 includes a first air distribution pipe 111 and a first connecting pipe 112. The first air distribution pipe 111 is connected to the air source 130 and communicates with the first connecting pipe 112. Hot air from the air source 130 can be distributed to the first connecting pipe 112 through the first air distribution pipe 111. Both the first air distribution pipe 111 and the first connecting pipe 112 include a first air outlet 113. The first air outlet 113 cooperates with the lock body of the battery swapping vehicle. More specifically, the number and position of the first air outlet 113 correspond to the number and position of the lock body, so as to blow hot air to the ice layer at each lock body to melt the ice layer, so as to facilitate the subsequent unlocking and unlocking of the lock body.

[0048] In this example scheme of Embodiment 1, such as Figure 3 As shown, the first air distribution duct 111 extends along the Y direction of the battery swapping vehicle. The first connecting pipe 112 includes a first extension section 114 extending along the Y direction of the battery swapping vehicle. One end of the first extension section 114 is connected to the first air distribution duct 111, and the other end is connected to a nozzle 115. The first air outlet 113 is located on the nozzle 115. The nozzle 115 cooperates with the lock body of the battery swapping vehicle to output hot air to the lock body.

[0049] For example, such as Figure 3 As shown, the number of first air distribution pipes 111 is set to one, and the first connecting pipes 112 are symmetrically arranged on both sides of the first air distribution pipe 111 in the X direction of the battery swapping vehicle. The number of nozzles 115 is set to ten, of which two nozzles 115 are located on the first air distribution pipe 111 to correspond to the number and position of the lock bodies. It can be understood that the number of nozzles 115 is set according to the number of lock bodies.

[0050] Optionally, the nozzle 115 is welded to the first air distribution pipe 111 and the first connecting pipe 112.

[0051] Optionally, the air source 130 uses a high-power hot air blower to output strong hot air. Understandably, hot air refers to airflow with a temperature higher than the temperature of ice or a clean environment; the temperature of the hot air output by the air source 130 can be adjusted as needed.

[0052] In this example scheme of embodiment one, combined with Figure 1 and Figure 3 A first control component 116 is connected between the first air duct 111 and the air source 130. The first control component 116 can adjust the airflow between the air source 130 and the first air duct 111 to adjust whether the lock body blower 110 outputs hot air according to the progress and needs of cleaning the bottom of the battery swapping vehicle.

[0053] In one embodiment, combined with Figure 1 and Figure 3 The battery pack blower 120 includes a second air distribution pipe 121 and a second connecting pipe 122. The second air distribution pipe 121 is connected to the air source 130 and communicates with the second connecting pipe 122. Hot air from the air source 130 can be distributed to the second connecting pipe 122 through the second air distribution pipe 121. Both the second air distribution pipe 121 and the second connecting pipe 122 include a plurality of second air outlets 123. The hot air output from the second air outlets 123 can at least cover the bottom surface of the battery pack to ensure the de-icing efficiency of the battery pack.

[0054] In this example scheme of Embodiment 1, such as Figure 3 As shown, the second air duct 121 extends along the Y direction of the battery swapping vehicle. The second connecting pipe 122 includes a second extension section 124 and a third extension section 125. The second extension section 124 is connected to the second air duct 121 and the third extension section 125. The second extension section 124 is matched with the Y-direction dimension of the bottom surface of the battery pack, and the third extension section 125 is matched with the X-direction dimension of the bottom surface of the battery pack, so as to achieve a good de-icing effect on the battery pack.

[0055] For example, the second extension section 124 extends along the Y direction of the battery swapping vehicle, the middle part of the second extension section 124 is connected to the second air distribution pipe 121, the third extension section 125 is connected to both ends of the second extension section 124, and the third extension section 125 extends along the X direction of the battery swapping vehicle.

[0056] For example, there are two battery pack blowers 120, which are symmetrically distributed on both sides of the first air distribution pipe 111 in the X direction of the battery swapping vehicle. This arrangement can ensure that the pipeline is neatly arranged and easy to maintain.

[0057] In this example scheme of embodiment one, combined with Figure 1 and Figure 3 A second control component 126 is connected between the second air duct 121 and the air source 130. The second control component 126 can adjust the airflow between the air source 130 and the second air duct 121 to adjust whether the battery pack blower 120 outputs hot air according to the progress and needs of cleaning the bottom of the battery swapping vehicle.

[0058] In one embodiment, such as Figure 3 As shown, the blower mechanism 100 also includes an integrated component 140. The lock body blower 110 and the battery pack blower 120 are connected as one unit through the integrated component 140. Several branch pipes 141 are connected to the integrated component 140, and the branch pipes 141 are connected to the lock body blower 110 and the battery pack blower 120.

[0059] In this example of embodiment one, the battery pack blower 120 is mounted in the Z direction of the battery swapping vehicle and connected above the lock body blower 110. Since the battery pack blower 120 has a number of second air outlets 123, the lock body blower 110 can support the battery pack blower 120 and ensure that the second air outlets 123 are not blocked, which helps to improve the stability of the airflow from the second air outlets 123 and improves the cleaning efficiency of the bottom of the battery swapping vehicle.

[0060] In this example of embodiment 1, the integrated component 140 includes an air cavity, one end of the first air distribution pipe 111 is connected to the integrated component 140 and communicates with the air cavity, and the branch pipe 141 connects the ventilation cavity and the first connecting pipe 112. The integrated component 140 can play the role of air distribution, and the branch pipe 141 can play the role of connecting the first connecting pipe 112 and the first air distribution pipe 111.

[0061] In this example scheme of embodiment one, combined with Figure 1 and Figure 3 The integrated component 140 also includes an air distribution component 142, which is located between the air source 130 and the lock body blower 110 and the battery pack blower 120. More specifically, the first air distribution pipe 111 and the second air distribution pipe 121 are both connected to the air source 130 through the air distribution component 142 to achieve integration and airflow distribution.

[0062] For example, the first control element 116 is disposed between the air distribution element 142 and the first air distribution duct 111.

[0063] For example, the second control element 126 is disposed between the air distribution element 142 and the second air distribution duct 121.

[0064] For example, the piping involved in the blower mechanism 100 and the ice scraper mechanism 200 is made of PPR (Polypropylene Random Copolymer), which is lightweight, easy to process, install and connect, and inexpensive, which helps to reduce investment costs. It also has less heat loss when conveying hot air, and is relatively soft, so it will not damage the battery pack and its locking components even if it comes into contact with the bottom of the battery swapping vehicle. When connecting the pipes, PTFE tape can be wrapped around them to ensure the sealing of the piping.

[0065] In one embodiment, such as Figure 4 As shown, the ice scraping mechanism 200 includes a scraper 210 and an adjusting member 220. The scraper 210 is able to contact the ice layer on the bottom of the battery swapping vehicle. The scraper 210 is mounted on the adjusting member 220, which is configured to allow the scraper 210 to move along the Z direction of the battery swapping vehicle to adjust the height of the scraper 210 relative to the bottom of the battery swapping vehicle.

[0066] During the bottom cleaning process of the battery swapping vehicle, the thickness of the ice layer gradually decreases, and the scraper 210 may not be able to contact the ice layer. The adjusting component 220 can adjust the height of the scraper 210 so that the scraper 210 can adjust its position according to the thickness of the ice layer and always maintain contact with the ice layer to achieve the ice scraping operation. The scraper 210 can also remove dirt from the bottom of the battery swapping vehicle. After the blower mechanism 100 blows hot air to the bottom of the battery swapping vehicle, the ice layer gradually melts, and the scraper 210 can clean the ice layer and dirt. In particular, some stubborn dirt that cannot be removed by melting ice layer can be effectively removed by the scraper 210, which helps to ensure the cleaning quality of the lock body and battery pack.

[0067] In this example scheme of Embodiment 1, such as Figure 5 As shown, the scraper 210 includes a blade 211 and a collection groove 212. At least one blade 211 is located on one side of the collection groove 212. The blade 211 can contact the ice layer on the bottom of the battery swapping vehicle. When the blade 211 moves relative to the bottom of the battery swapping vehicle, part of the ice scraped off by the blade 211 can be collected in the collection groove 212.

[0068] For example, the number of blades 211 is set to two. The two blades 211 are opposite each other in the Y direction of the battery swapping vehicle through the collection groove 212. The two blades 211 cooperate to effectively scrape off the ice layer, which helps to ensure the stability and efficiency of cleaning.

[0069] For example, the blade 211 extends along the X direction of the battery swapping vehicle, and its length is matched with the battery pack and its lock body.

[0070] For example, the scraper 210 is made of nylon, which can ensure cleaning quality and is not easy to scratch the battery pack and its lock body at the bottom of the battery swapping vehicle during use.

[0071] For example, the blade 211 is a two-way blade. When the entire cleaning device enters under the battery swapping vehicle, the blade 211 can perform a first scraping effect. When the entire cleaning device is withdrawn, the blade 211 can perform a second scraping effect. It can also scrape away melted water stains, preventing water stains from remaining on the bottom of the battery swapping vehicle, which helps to improve the safety of battery swapping.

[0072] For example, the collection slot 212 is configured as an arc-shaped slot.

[0073] In this example scheme of embodiment one, combined with Figure 4 and Figure 5 The adjusting component 220 includes a mounting base 221 and an elastic element 222. The scraper 210 is mounted on the mounting base 221 via the elastic element 222. When cleaning is performed, the scraper 210 contacts the ice layer at the bottom of the battery swapping vehicle, and the elastic element 222 is in a compressed state. As the ice layer gradually thins, the elastic element 222 gradually returns to its original position and drives the scraper 210 to rise, so that the scraper 210 can always maintain a state of contact with the ice layer to achieve a good cleaning effect.

[0074] For example, such as Figure 5 As shown, the mounting base 221 includes a cavity 223, within which a guide post 224 is disposed. The guide post 224 extends along the Z-direction of the battery swapping vehicle. An elastic element 222 is at least partially sleeved on the guide post 224, with one end of the elastic element 222 away from the guide post 224 connected to the scraper 210. The guide post 224 ensures that the elastic element 222 stably provides a force along the Z-direction of the battery swapping vehicle to the scraper 210, thereby efficiently adjusting the height of the scraper 210.

[0075] For example, such as Figure 5 As shown, a limiting groove is provided at the lower end of the scraper 210, and the upper part of the elastic element 222 is installed in the limiting groove to ensure the installation quality and elastic deformation capability of the elastic element 222.

[0076] For example, the elastic element 222 is a compression spring.

[0077] In one embodiment, such as Figure 4 As shown, the ice-scraping mechanism 200 also includes a guide 230, combined with... Figure 5The guide 230 is installed between the scraper 210 and the adjuster 220. The adjuster 220 is configured to adjust the height of the scraper 210 and the guide 230. The guide 230 includes a guide wheel 231. At least one guide wheel 231 is installed on one side of the scraper 210 in the Y direction. The central axis of the guide wheel 231 is arranged along the X direction of the vehicle.

[0078] When the entire cleaning device enters the underside of the battery swapping vehicle to perform de-icing and cleaning operations, the guide wheel 231 can contact the ice layer on the bottom of the battery swapping vehicle to play a guiding role. This helps to improve the stability and convenience of the entire cleaning device in conjunction with the bottom of the battery swapping vehicle, making the position of the entire cleaning device accurate, reducing the collision between the cleaning device and the bottom of the battery swapping vehicle when entering and exiting the vehicle, and ensuring the de-icing quality of the scraper 210, avoiding the problem of scratching the bottom of the battery swapping vehicle due to the instability of the scraper 210.

[0079] In this example scheme of embodiment one, combined with Figure 4 and Figure 5 The guide component 230 also includes a base 232. The guide wheel 231 is mounted on the base 232 and can rotate around its own axis via a rotating shaft. The base 232 is mounted on the mounting base 221 via an elastic element 222. The upper end of the elastic element 222 is connected to the base 232. The scraper 210 is mounted on the base 232. The height of the base 232 can be adjusted by the elastic deformation of the elastic element 222, and the height of the scraper 210 and the guide wheel 231 can be adjusted synchronously so that the scraper 210 and the guide wheel 231 can always be in contact with the ice layer on the bottom of the battery swapping vehicle until the cleaning is completed.

[0080] For example, the number of guide wheels 231 is set to two, and the two guide wheels 231 are installed opposite each other on both sides of the scraper 210 in the Y direction to ensure the stability of the scraper 210 in the process of scraping the ice layer.

[0081] In one embodiment, combined with Figure 1 and Figure 2 The bottom cleaning device for battery swapping vehicles proposed in this utility model also includes a positioning mechanism 300. The positioning mechanism 300 includes a first positioning member 310 and a second positioning member 320 disposed on both sides of the blower mechanism 100. The first positioning member 310 and the second positioning member 320 can contact the two side edges of the battery pack to play a positioning role, so that the blower mechanism 100 and the ice scraping mechanism 200 can cooperate with the positions of the battery pack and the lock body, so as to avoid the position of the blower mechanism 100 and the ice scraping mechanism 200 shifting during use and affecting the de-icing efficiency, and reduce the operation of adjusting the position, thereby improving convenience and efficiency.

[0082] In this example scheme of Embodiment 1, such as Figure 6As shown, the front ends of the first positioning member 310 and the second positioning member 320 are equipped with ice scraping members 330. The ice scraping members 330 can contact the ice layer between the two ends of the battery pack and the bottom of the battery swapping vehicle to scrape off the ice layer, thereby facilitating positioning.

[0083] For example, the first positioning member 310 and the second positioning member 320 are opposite each other in the X direction of the battery swapping vehicle.

[0084] For example, such as Figure 3 As shown, the first positioning member 310 and the second positioning member 320 have at least partially overlapping or completely non-overlapping orthogonal projections in the X direction of the battery swapping vehicle. Furthermore, the first positioning member 310 and the second positioning member 320 are offset in the X direction of the battery swapping vehicle. This arrangement ensures that the first positioning member 310 and the second positioning member 320 contact the two ends of the battery pack as much as possible, so as to reduce the size of the first positioning member 310 and the second positioning member 320 while ensuring the positioning effect, which is beneficial to weight reduction and can save investment costs.

[0085] In this example scheme of Embodiment 1, such as Figure 6 As shown, the positioning mechanism 300 also includes a third positioning member 340, which can contact the rear end of the battery pack of the battery swapping vehicle to ensure that the blower mechanism 100 and the ice scraper mechanism 200 can move to the appropriate position at the bottom of the battery swapping vehicle in one go.

[0086] For example, the third positioning member 340 is connected to the rear end of the first positioning member 310 and / or the second positioning member 320.

[0087] For example, the positioning mechanism 300 uses nylon parts to avoid scratching the bottom of the battery swapping vehicle.

[0088] In one embodiment, such as Figure 1 As shown, the bottom cleaning device for battery swapping vehicles proposed in this utility model also includes a main body 400. The aforementioned blower mechanism 100, ice scraper mechanism 200, positioning mechanism 300 and air source 130 are all installed on the main body 400. The main body 400 is configured to be able to move relative to the bottom of the battery swapping vehicle, thereby enabling the blower mechanism 100, ice scraper mechanism 200 and positioning mechanism 300 to move relative to the bottom of the battery swapping vehicle.

[0089] In this first embodiment, a wheel 410 is mounted on the lower end of the main body 400 to facilitate movement of the main body 400. In another embodiment, a slide rail assembly is provided on the lower end of the main body 400 to facilitate movement of the main body 400.

[0090] In this example scheme of Embodiment 1, such as Figure 1As shown, the main body 400 includes a first mounting bracket 420 and a second mounting bracket 430. The aforementioned air source 130 is mounted on the first mounting bracket 420, and the blower mechanism 100, the ice scraper mechanism 200 and the positioning mechanism 300 are mounted on the second mounting bracket 430. The ice scraper mechanism 200 is located in front of the blower mechanism 100.

[0091] When the cleaning device enters under the battery swapping vehicle, the ice scraping mechanism 200 contacts the ice layer before the blower mechanism 100. During the entry process, it can scrape off the ice layer. When the cleaning device reaches the appropriate position, the blower mechanism 100 outputs hot air to melt the ice layer. When the cleaning device is transported out from under the battery swapping vehicle, the ice scraping mechanism 200 can scrape off the ice layer again during the exit process and can also scrape off water stains. This process is repeated, and the bidirectional ice scraping operation of the ice scraping mechanism 200 can achieve effective de-icing and cleaning.

[0092] For example, such as Figure 1 As shown, a push rod 421 is mounted on the first mounting bracket 420 to facilitate the operator's use and operation of the entire cleaning device. The push rod 421 is detachably connected to the first mounting bracket 420 for easy disassembly and storage.

[0093] For example, the first mounting bracket 420 and the second mounting bracket 430 are detachably connected to facilitate the disassembly and storage of the entire cleaning device and to reduce the storage space occupied when the entire cleaning device is not in use. The first mounting bracket 420 and the second mounting bracket 430 are detachably connected by means of screws, snaps, or the like.

[0094] For example, the lock body blower 110 and the battery pack blower 120 are detachably mounted on the second mounting bracket 430 via the integration component 140. To improve stability, the pipes of the lock body blower 110 and the battery pack blower 120 can be fixed to the second mounting bracket 430 by means of cable ties, tape, etc.

[0095] Since the battery pack specifications, lock body positions and quantities vary among different battery swapping vehicles, the integrated component 140 can integrate the lock body blower 110 and the battery pack blower 120 into one unit and install it on the main body 400. The integrated component 140 can be removed as needed, thereby allowing the lock body blower 110 and the battery pack blower 120 to be replaced as a whole to meet cleaning needs and improve versatility.

[0096] For example, both the first mounting bracket 420 and the second mounting bracket 430 include several profiles detachably connected by corner joints to achieve detachable assembly. When not in use, the first mounting bracket 420 and the second mounting bracket 430 can be disassembled into their smallest units for easy storage. The profiles can be made of aluminum, which is lightweight and has good structural stability.

[0097] In this example scheme of Embodiment 1, such as Figure 5 As shown, the ice scraping mechanism 200 also includes an integrated base 240, on which the base 232 is mounted and on the main body 400 via the integrated base 240.

[0098] For example, the integrated base 240 is detachably mounted on the front side of the main body 400, and the mounting method can be screwed, snap-fit, etc., to facilitate disassembly and maintenance.

[0099] This utility model also proposes a battery swapping station for performing battery swapping operations on battery swapping vehicles, and the battery swapping station is equipped with the aforementioned battery swapping vehicle bottom cleaning device.

[0100] In one embodiment, the battery swapping station includes a battery swapping platform, where battery swapping vehicles perform battery swapping. A cleaning area is provided on one side of the battery swapping platform, and the cleaning device at the bottom of the battery swapping vehicle is stored in the cleaning area. Before performing battery swapping, the battery swapping vehicle first drives to the cleaning area for de-icing and cleaning, thereby ensuring the operational safety of the entire battery swapping station.

[0101] In this example embodiment, a guide rail is provided in the cleaning area to guide the bottom cleaning device of the battery swapping vehicle, so as to facilitate the operation of the cleaning device.

[0102] In this example scheme of Embodiment 1, a camera is provided in the cleaning area. The camera is used to observe and photograph the bottom of the battery swapping vehicle to confirm the icing situation on the bottom of the battery swapping vehicle.

[0103] 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.
