Description

Technical Field

[0001] The present application relates to the field of battery replacement technology, and in particular to a deicing device and a battery replacement station. Background Art

[0002] When a vehicle is driving in a low temperature environment, such as when the vehicle is driving in rainy and snowy weather, the snow on the road will splash onto the chassis of the vehicle, causing the chassis of the vehicle to freeze. However, when the vehicle needs to replace the battery, the battery may be covered with ice and cannot be removed, resulting in battery replacement failure. How to de-ice the battery is an urgent problem to be solved. Utility Model Content

[0003] The present application provides a deicing device and a battery swap station, which can enhance deicing efficiency and improve deicing effect.

[0004] In a first aspect, the present application provides a deicing device, which includes a liquid storage mechanism, a heating mechanism and a nozzle. The liquid storage mechanism has a receiving chamber for receiving deicing liquid, and the receiving chamber has an opening at the upper end in the vertical direction. The heating mechanism is arranged in the liquid storage mechanism and is used to heat the deicing liquid. The nozzle is arranged in the liquid storage mechanism and is used to spray the deicing liquid, and in the vertical direction, the projection of the nozzle is located within the projection of the opening.

[0005] When it is necessary to de-ice the de-icing parts (such as batteries), the de-icing equipment can be moved to the lower side of the ice layer; the nozzle sprays the heated de-icing liquid toward the ice layer, and the ice layer falls off from the de-icing parts under the impact of the high-temperature de-icing liquid. There is an opening on the upper side of the accommodating chamber, and the nozzle is located within the range corresponding to the opening in the vertical direction. Therefore, the detached ice layer, melted water and de-icing liquid can enter the accommodating chamber through the opening, thereby reducing pollution to the surrounding environment and improving the battery replacement environment. The liquid storage mechanism can recycle the de-icing liquid, thereby reducing the frequency of liquid replenishment and improving the de-icing efficiency.

[0006] In some embodiments, the nozzle is contained in the receiving cavity, and the nozzle is smaller than the opening, so that the deicing liquid splashing outside the receiving cavity can be reduced during deicing, thereby improving the recovery efficiency of the deicing liquid and improving the battery replacement environment.

[0007] In some embodiments, the deicing device further includes a first driving mechanism, which is connected to the nozzle and used to drive the nozzle to move in a first direction, and the first direction is perpendicular to the vertical direction. The first driving mechanism can drive the nozzle to translate in the first direction to increase the deicing area of ​​the deicing device, remove residual ice and impurities remaining in the dead corner at the bottom of the battery, and improve the deicing efficiency. By setting the first driving mechanism, the movement of the nozzle can be automated.

[0008] In some embodiments, the first driving mechanism includes a base, a guide rail and a first driving member. The guide rail is disposed in the accommodating chamber and fixed to the liquid storage mechanism. The guide rail extends along a first direction. The base is disposed on the guide rail. The nozzle is installed on the base. The first driving member is connected to the base and is used to drive the base to move along the first direction.

[0009] The base can provide support for the nozzle, and the first driving member and the guide rail can drive the nozzle to reciprocate along the first direction, thereby improving the deicing effect.

[0010] In some embodiments, the deicing device further comprises a scraper, which is connected to the first driving mechanism and is located on the upper side of the nozzle. The first driving mechanism can drive the scraper to move in a first direction to accelerate the shedding of the ice layer and scrape off ice debris, mud, snow and other impurities remaining on the surface of the battery, thereby cleaning the battery. The scraper and the sprayed deicing liquid can perform secondary treatment on the ice layer, thereby improving the deicing effect and improving the deicing efficiency.

[0011] In some embodiments, there are multiple nozzles, at least two of which are arranged along the second direction, and the vertical direction, the first direction, and the second direction are perpendicular to each other. By providing multiple nozzles, the deicing efficiency can be improved. Compared with the solution of using a long nozzle, the solution of providing multiple small-sized nozzles can reduce the total weight of the deicing equipment and reduce the difficulty of forming a single nozzle; in addition, after a single nozzle is worn, it only needs to be replaced accordingly, thereby reducing maintenance costs.

[0012] In some embodiments, the angle between the spray direction of the nozzle and the vertical direction is 10°-50°. The flow direction of the deicing liquid forms a certain angle with the ice layer, thereby applying a certain tangential force to the ice layer, causing the ice layer to fall off quickly.

[0013] In some embodiments, the deicing device includes a first filter element, which is disposed in a receiving chamber. The nozzle is disposed on the upper side of the first filter element, and the heating mechanism is disposed in the receiving chamber and located on the lower side of the first filter element. The first filter element can block large pieces of ice from falling off, reduce the risk of ice layers crushing the heating mechanism, and mitigate the effect of ice layers on the temperature of the deicing liquid. In addition, the first filter element can also filter out some impurities attached to the ice layer to reduce contamination of the deicing liquid.

[0014] In some embodiments, the first filter element comprises a filter screen, which has a simple structure and can support the ice layer and filter impurities.

[0015] In some embodiments, the deicing device further comprises a pressure pump disposed in the liquid storage mechanism, the pressure pump being connected to the nozzle, and the pressure pump being used to deliver the deicing liquid in the receiving chamber to the nozzle. The pressure pump can spray the deicing liquid at a certain pressure, thereby increasing the impact force of the deicing liquid on the ice layer, so that the ice layer falls off quickly.

[0016] In some embodiments, the deicing device further comprises a second filter element, the second filter element is disposed in the receiving chamber, and the pressure pump is connected to the second filter element. The pressure pump extracts deicing liquid from the receiving chamber via the second filter element. During the circulation of the deicing liquid, the second flow element can filter out impurities (such as mud and sand) in the deicing liquid, thereby reducing the risk of the deicing liquid contaminating the battery.

[0017] In some embodiments, the liquid storage mechanism includes a bottom plate and a side plate connected to the bottom plate, the side plate surrounds the bottom plate, and the bottom plate is opposite to the opening. In the vertical direction, the side plate is higher than the nozzle. The part of the side plate that is higher than the nozzle can shield the high-temperature deicing liquid from the periphery, reduce the deicing liquid splashing outward, reduce heat loss, and improve the deicing effect and the battery replacement environment.

[0018] In some embodiments, the side panel includes a side panel body and a flexible portion connected to the side panel body, the flexible portion is located on the upper side of the side panel body, and the flexible portion defines an opening. The flexible portion can be against the vehicle to create a relatively closed space between the vehicle and the liquid storage mechanism, thereby reducing the deicing liquid splashing outward. The flexible portion is flexible, and when it is against the vehicle, it is not easy to crush the vehicle. When the vehicle is continuously tilted, the flexible portion can be adaptively deformed to improve the sealing of the contact surface between the flexible portion and the vehicle.

[0019] In some embodiments, the deicing device further includes a second driving mechanism, which is connected to the liquid storage mechanism and is used to drive the liquid storage mechanism to rise and fall. For vehicle models with different heights of the battery from the ground, the second driving mechanism can adjust the height of the liquid storage mechanism and the nozzle so that the liquid storage mechanism can block the deicing liquid and reduce the splashing of the deicing liquid.

[0020] In some embodiments, the deicing device further comprises a plurality of wheels, and the plurality of wheels support the liquid storage mechanism. By providing a plurality of wheels, the resistance to the movement of the deicing device can be reduced, and the deicing efficiency can be improved. The deicing device can be pushed manually, and has the characteristics of convenient movement and rapid transfer.

[0021] In a second aspect, the present application provides a battery swap station, which includes the deicing equipment and the battery swap compartment provided by any embodiment of the first aspect. The deicing equipment is used to remove the ice layer attached to the battery of the vehicle. The battery swap compartment is used to replace the battery of the vehicle.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0034] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0037] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0038] The term “plurality” used in this application refers to two or more (including two).

[0039] In the embodiments of the present application, "parallel" includes not only the absolutely parallel situation, but also the roughly parallel situation conventionally recognized in engineering; at the same time, "vertical" includes not only the absolutely vertical situation, but also the roughly vertical situation conventionally recognized in engineering.

[0040] With the development of new energy technology, more and more devices use batteries. When the vehicle runs out of power, it is often connected to a charging device to replenish power. For example, electric vehicles can be connected to a charging pile for charging. Charging takes a long time and affects the user experience. Compared with charging, replacing the battery can replenish power faster.

[0041] When a vehicle is driving in a low temperature environment, such as when the vehicle is driving in rainy and snowy weather, the snow on the road will splash onto the chassis of the vehicle, causing the chassis of the vehicle to freeze. However, when the vehicle needs to replace the battery, the battery may be covered by ice and cannot be removed, resulting in a failure in battery replacement.

[0042] In the related art, workers usually spray liquid on the battery to remove the ice attached to the battery, so that the battery can be replaced smoothly. However, the sprayed liquid cannot be recovered, which causes liquid waste and requires continuous replenishment of liquid, increasing the cost of deicing. In addition, the sprayed liquid will also remain on the bottom surface, polluting the environment of the battery swap station.

[0043] In view of this, an embodiment of the present application provides a deicing device, which, by providing a liquid storage mechanism with an opening, recovers the sprayed liquid and the ice layer that falls off the battery, thereby reducing the frequency of liquid replenishment, improving the deicing efficiency, and improving the battery replacement environment.

[0044] The deicing device disclosed in the embodiment of the present application can be used to deice the battery of the vehicle, and can also be used to deice other positions of the vehicle. Of course, the deicing device can also be used to deice other equipment, buildings, etc. that are prone to ice.

[0045] Figure 1 A schematic diagram of the structure of a deicing device provided in some embodiments of the present application; Figure 2 A simplified schematic diagram of a de-icing device provided for some embodiments of the present application.

[0046] Reference Figure 1 and Figure 2 The embodiment of the present application provides a deicing device 1, which includes a liquid storage mechanism 10, a heating mechanism 20 and a nozzle 30. The liquid storage mechanism 10 has a receiving chamber 11 for receiving deicing liquid, and the receiving chamber 11 has an opening 11a at the upper end along the vertical direction Z. The heating mechanism 20 is arranged in the liquid storage mechanism 10 and is used to heat the deicing liquid. The nozzle 30 is arranged in the liquid storage mechanism 10 and is used to spray the deicing liquid. In the vertical direction Z, the projection of the nozzle 30 is located within the projection of the opening 11a.

[0047] The de-icing liquid can be water, alkaline solution or other liquids.

[0048] The heating mechanism 20 may be disposed in the accommodating chamber 11 to directly heat the deicing liquid. Alternatively, the heating mechanism 20 may also be disposed outside the accommodating chamber 11, and the heating mechanism 20 may heat the deicing liquid through the cavity wall of the accommodating chamber 11.

[0049] The number of the nozzle 30 may be one or more.

[0050] The nozzle 30 may be disposed in the accommodating chamber 11 or outside the accommodating chamber 11. For example, the nozzle 30 may be disposed on the upper side of the opening 11a.

[0051] When it is necessary to de-ice the de-icing parts (such as batteries), the de-icing device 1 can be moved to the lower side of the ice layer; the nozzle 30 sprays the heated de-icing liquid toward the ice layer, and the ice layer falls off from the de-iced parts under the impact of the high-temperature de-icing liquid. The upper side of the accommodating chamber 11 has an opening 11a, and the nozzle 30 is located in the range corresponding to the opening 11a along the vertical direction Z. Therefore, the detached ice layer, melted water and de-icing liquid can enter the accommodating chamber 11 through the opening 11a, thereby reducing pollution to the surrounding environment and improving the battery replacement environment. The liquid storage mechanism 10 can recycle the de-icing liquid, thereby reducing the frequency of liquid replenishment and improving the de-icing efficiency.

[0052] In order to simplify the description, the following description takes the battery of a vehicle as the part to be de-iced.

[0053] In some embodiments, the deicing device 1 can be used to remove ice accumulation from the battery at the bottom of a heavy truck. When a heavy truck is driving on a winter road in the north, a mixture of ice, snow, and mud is thrown to the bottom of the battery by the wheels, causing dirt to accumulate at the bottom of the battery. In addition, the overall temperature in winter is low, and a hard and thick mixture of ice and snow forms at the bottom of the battery, making it difficult for the heavy truck to replace the battery. The high-temperature deicing liquid impacts the bottom of the battery to remove the ice and mud mixture attached to the battery, allowing the heavy truck to replace the battery smoothly at the battery replacement station.

[0054] In some embodiments, the deicing liquid includes water. The water after the ice layer melts can be used as a supplement to the deicing liquid.

[0055] In some embodiments, the heating mechanism 20 can heat the de-icing liquid to a temperature of 30°C-80°C.

[0056] As an example, the heating mechanism 20 may heat the temperature of the de-icing liquid to 30°C, 35°C, 40°C, 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, 75°C, or 80°C.

[0057] The temperature of the deicing liquid is heated to above 30°C to increase the temperature difference between the deicing liquid and the ice layer and improve the deicing efficiency. The temperature of the deicing liquid is limited to less than or equal to 80°C to reduce the risk of high-temperature deicing liquid damaging the battery.

[0058] Optionally, the heating mechanism 20 may heat the temperature of the de-icing liquid to 50°C-70°C.

[0059] In some embodiments, the heating mechanism 20 includes a plurality of heating elements 21. Optionally, the plurality of heating elements 21 are arranged in an array. Optionally, the heating element 21 includes a heating rod.

[0060] In some embodiments, the spray head 30 is accommodated in the accommodating chamber 11 .

[0061] The nozzle 30 may be entirely accommodated in the accommodation chamber 11 , or may be partially accommodated in the accommodation chamber 11 .

[0062] The nozzle 30 is smaller than the opening 11a, which can reduce the deicing liquid splashing outside the accommodating chamber 11 during deicing, thereby improving the recovery efficiency of the deicing liquid and improving the battery replacement environment.

[0063] In some embodiments, the spray head 30 is configured to be movable along a first direction X, which is perpendicular to the vertical direction Z.

[0064] Exemplarily, the movement of the spray head 30 along the first direction X may be driven manually or by other power components. For example, the deicing device 1 may be pushed manually to move the spray head 30 along the first direction X.

[0065] In some embodiments, the deicing device 1 further includes a first driving mechanism 40 , which is connected to the nozzle 30 and is used to drive the nozzle 30 to move along a first direction X, where the first direction X is perpendicular to the vertical direction Z.

[0066] The first driving mechanism 40 can drive the nozzle 30 to translate along the first direction X to increase the deicing area of ​​the deicing device, remove the residual ice impurities remaining in the dead corner of the bottom of the battery, and improve the deicing efficiency. By setting the first driving mechanism 40, the movement of the nozzle 30 can be automated to improve the deicing efficiency.

[0067] In some embodiments, the first driving mechanism 40 includes a base 41, a guide rail 42 and a first driving member 43. The guide rail 42 is disposed in the accommodating chamber 11 and fixed to the liquid storage mechanism 10. The guide rail 42 extends along the first direction X. The base 41 is disposed on the guide rail 42. The nozzle 30 is installed on the base 41. The first driving member 43 is connected to the base 41 and is used to drive the base 41 to move along the first direction X.

[0068] As an example, the first driving member 43 may include a cylinder, a hydraulic cylinder, a motor or other power components.

[0069] As an example, the first driving member 43 may be installed on the base 41 or on the liquid storage mechanism 10 .

[0070] The base 41 can provide support for the nozzle 30 , and the first driving member 43 and the guide rail 42 can drive the nozzle 30 to reciprocate along the first direction X, thereby improving the deicing effect.

[0071] In some embodiments, two guide rails 42 are provided, and the two guide rails 42 are respectively provided on both sides of the base 41 along the second direction Y. The first direction X, the second direction Y and the vertical direction Z are perpendicular to each other.

[0072] In some embodiments, the guide rail 42 is provided with a rack extending along the first direction X, and the first driving member 43 is fixed to the base 41, and the first driving member 43 includes a motor and a gear, and the gear is meshed with the rack. The motor drives the gear to rotate, thereby driving the base 41 to move along the first direction X.

[0073] In some embodiments, the de-icing device 1 further includes a scraper 50 , which is connected to the first driving mechanism 40 and is located on the upper side of the spray head 30 .

[0074] It can be understood that “the scraper 50 is located on the upper side of the spray head 30 ” does not require that the scraper 50 is located directly above the spray head 30 , as long as the scraper 50 is higher than the spray head 30 .

[0075] The scraper 50 may be disposed in the accommodating cavity 11 , or may be higher than the opening 11 a .

[0076] The first driving mechanism 40 can drive the scraper 50 to move along the first direction X to accelerate the shedding of the ice layer and scrape off the ice debris, mud, snow and other impurities remaining on the battery surface, thereby cleaning the battery. The scraper 50 and the sprayed deicing liquid can perform secondary treatment on the ice layer, thereby improving the deicing effect and improving the deicing efficiency.

[0077] In some embodiments, the scraper 50 is fixed to the base 41. The scraper 50 and the spray head 30 can move synchronously along the first direction X, thereby improving the deicing effect.

[0078] In some embodiments, the scraper 50 is made of a flexible material. The scraper 50 may scrape the battery when scraping off the ice layer; the use of a flexible material can reduce the risk of the battery being scratched. Optionally, the scraper 50 is a rubber scraper.

[0079] In some embodiments, there are a plurality of nozzles 30 , and at least two of the plurality of nozzles 30 are arranged along the second direction Y. The vertical direction Z, the first direction X, and the second direction Y are perpendicular to each other.

[0080] The plurality of nozzles 30 may be arranged at equal intervals or at unequal intervals.

[0081] The deicing efficiency can be improved by providing multiple nozzles 30. Compared with the solution of using a long nozzle 30, the solution of providing multiple small-sized nozzles 30 can reduce the total weight of the deicing device 1 and reduce the difficulty of forming a single nozzle 30; in addition, after a single nozzle 30 is worn, it only needs to be replaced accordingly, thereby reducing maintenance costs.

[0082] In some embodiments, the angle α between the spraying direction of the nozzle 30 and the vertical direction Z is 10°-50°.

[0083] As an example, the nozzle 30 has a nozzle, and the angle α may be the angle between the axial direction of the nozzle and the vertical direction Z.

[0084] As an example, α may be 10°, 20°, 30°, 40° or 50°.

[0085] The flow direction of the de-icing liquid is at a certain angle to the ice layer, thereby applying a certain tangential force to the ice layer, causing the ice layer to fall off quickly.

[0086] In some embodiments, the scraper 50 and the spray head 30 may overlap in the vertical direction Z; since the spraying direction of the spray head 30 is inclined compared to the vertical direction Z, the scraper 50 may avoid the deicing liquid.

[0087] In some embodiments, the deicing device 1 includes a first filter 60 disposed in the accommodating chamber 11 , a nozzle 30 disposed on the upper side of the first filter 60 , and a heating mechanism 20 disposed in the accommodating chamber 11 and located on the lower side of the first filter 60 .

[0088] The first filter element 60 can block the large pieces of ice that fall off, reduce the risk of ice crushing the heating mechanism 20, and mitigate the effect of ice on the temperature of the deicing liquid. In addition, the first filter element 60 can also filter out some impurities attached to the ice layer, reducing the pollution to the deicing liquid.

[0089] In some embodiments, the first filter element 60 includes a filter screen, which can support the ice layer and filter impurities.

[0090] In some embodiments, the filter screen is a rigid filter screen. When a large piece of ice falls onto the filter screen, the rigid filter screen is less deformed and can provide effective support, thereby reducing the risk of the ice layer crushing the heating mechanism 20.

[0091] In some embodiments, the liquid storage mechanism 10 includes a bottom plate 12 and a side plate 13 connected to the bottom plate 12 , the side plate 13 surrounds the bottom plate 12 , and the bottom plate 12 is opposite to the opening 11 a .

[0092] In some examples, the side plate 13 is a square tube structure or a cylindrical structure. Optionally, the side plate 13 is a square tube structure, which includes four plates connected in sequence along the circumference of the accommodating cavity 11.

[0093] In some embodiments, the outer periphery of the filter is fixed to the side plate 13 .

[0094] In some embodiments, the guide rail 42 is fixed to the side plate 13 and is located above the filter screen. Exemplarily, the base 41 and the scraper 50 are both located above the filter screen.

[0095] In some embodiments, the pore size of the filter screen is less than or equal to 10 mm. The pores of the filter screen can be circular or non-circular. For example, if the area of ​​the non-circular pore is equal to the area of ​​a circle with a diameter of D, then the pore size of the non-circular pore is D.

[0096] The filter has a smaller pore size and can filter out some impurities attached to the ice layer, reducing the contamination of the de-icing liquid.

[0097] In some embodiments, the deicing device 1 further includes a pressure pump 70 disposed in the liquid storage mechanism 10 , the pressure pump 70 is connected to the nozzle 30 , and the pressure pump 70 is used to transport the deicing liquid in the accommodating chamber 11 to the nozzle 30 .

[0098] The pressure pump 70 can spray the deicing liquid at a certain pressure, thereby increasing the impact force of the deicing liquid on the ice layer, causing the ice layer to fall off quickly.

[0099] In some embodiments, the pressure of the deicing liquid sprayed from the spray head 30 may be 5 MPa-30 MPa.

[0100] In some embodiments, the pressure pump 70 may be connected to the spray head 30 via a connecting tube (not shown).

[0101] In some embodiments, the connecting pipe may be located on the upper side of the first filter element 60 or on the lower side of the first filter element 60 .

[0102] Exemplarily, at least a portion of the connecting tube is disposed on the lower side of the first filter element 60. The first filter element 60 may have a passage for avoiding the connecting tube.

[0103] In some embodiments, the de-icing device 1 further includes a second filter element 80 , which is disposed in the accommodating chamber 11 , and the pressure pump 70 is connected to the second filter element 80 .

[0104] The booster pump 70 extracts the deicing liquid from the accommodating chamber 11 via the second filter element 80. During the circulation of the deicing liquid, the second flow element can filter out impurities (such as mud and sand) in the deicing liquid, thereby reducing the risk of the deicing liquid contaminating the battery.

[0105] In some embodiments, the second filter element 80 comprises a high flow filter.

[0106] In some embodiments, the filtering accuracy of the second filter element 80 is greater than the filtering accuracy of the first filter element 60 .

[0107] In some embodiments, the second filter element 80 extracts deicing liquid from a portion of the accommodating chamber 11 located below the first filter element 60. Exemplarily, the second filter element 80 is disposed on the bottom plate 12.

[0108] In some embodiments, the de-icing device 1 further includes a second driving mechanism 90 , which is connected to the liquid storage mechanism 10 and is used to drive the liquid storage mechanism 10 to rise and fall.

[0109] When the battery height is low, the second driving mechanism 90 can lower the liquid storage mechanism 10 and the spray, and when the battery height is high, the second driving mechanism 90 can raise the liquid storage mechanism 10 and the spray.

[0110] The embodiment of the present application can be applied to various vehicle models. For vehicle models with different heights of the battery from the ground, the second drive mechanism 90 can adjust the height of the liquid storage mechanism 10 and the nozzle 30 so that the liquid storage mechanism 10 can block the deicing liquid and reduce the splashing of the deicing liquid.

[0111] In some embodiments, the second driving mechanism 90 may include a second driving member and a transmission member (not shown).

[0112] The second driving member includes but is not limited to at least one of a motor, a cylinder and a hydraulic cylinder. The transmission member includes but is not limited to at least one of a scissor transmission structure, a connecting rod transmission structure, a cam transmission structure and a lead screw nut transmission structure.

[0115] Figure 3 Schematic diagram of deicing equipment provided in some other embodiments of the present application.

[0116] Reference Figure 3 In some embodiments, in the vertical direction Z, the side plate 13 is higher than the spray head 30 .

[0117] The portion of the side panel 13 that is higher than the nozzle 30 can shield the high-temperature deicing liquid from the periphery, reduce the deicing liquid splashing outward, reduce heat energy loss, and improve the deicing effect and power replacement environment.

[0118] In some embodiments, the upper end of the side plate 13 may abut against the vehicle to create a relatively closed space between the vehicle and the liquid storage mechanism 10, thereby reducing the de-icing liquid that splashes outward.

[0119] For example, when deicing is required, the deicing device 1 is first moved to the lower side of the ice layer; then, the second driving mechanism 90 drives the liquid storage mechanism 10 to rise so that the upper end of the side plate 13 abuts against the vehicle. Then, the nozzle 30 starts to spray high-temperature deicing liquid to start deicing. During the deicing process, a relatively closed space is formed between the vehicle and the liquid storage mechanism 10, and the side plate 13 can block the deicing liquid to reduce the deicing liquid splashing outward.

[0120] As an example, the upper end of the side plate 13 may be used to abut against the chassis of the vehicle so that at least a portion of the battery extends into the accommodating cavity 11 .

[0121] In some embodiments, the side plate 13 includes a side plate body 131 and a flexible portion 132 connected to the side plate body 131 . The flexible portion 132 is located on an upper side of the side plate body 131 . The flexible portion 132 defines an opening 11 a .

[0122] The flexible portion 132 can be pressed against the vehicle to create a relatively closed space between the vehicle and the liquid storage mechanism 10, thereby reducing the deicing liquid that splashes outward. The flexible portion 132 is flexible, and when pressed against the vehicle, it is not easy to crush the vehicle. When the vehicle continues to tilt, the flexible portion 132 can be adaptively deformed to improve the sealing of the contact surface between the flexible portion 132 and the vehicle.

[0123] In some embodiments, the flexible portion 132 is detachably mounted on the side plate body 131. When the flexible portion 132 is damaged, it can be easily replaced.

[0124] In some embodiments, the flexible portion 132 includes an outer covering layer 132 a and a filling portion 132 b , and the outer covering layer 132 a covers the filling portion 132 b from the outside.

[0125] Optionally, the outer covering layer 132a is made of waterproof material. Optionally, the outer covering layer 132a is a flexible waterproof cloth layer.

[0126] Optionally, the filling portion 132b includes a sponge.

[0129] Exemplarily, the battery swap compartment 4 can be used to remove a depleted battery from the vehicle 3 and install a new fully charged battery for the vehicle 3 .

[0130] Before the vehicle 3 enters the battery swap compartment 4 for battery swap, the de-icing equipment 1 can remove the ice layer on the lower side of the battery 2, thereby reducing the risk of battery swap failure and improving the battery swap efficiency.

[0131] In some embodiments, the battery swap station further includes a battery compartment 5. The battery compartment 5 is used to accommodate and charge the battery 2. The battery 2 removed from the vehicle 3 is transferred to the battery compartment 5 for charging; the fully charged battery in the battery compartment 5 can be installed on the chassis of the vehicle 3 to complete the battery swap.
