[0001] This application claims priority to Chinese Patent Application No. 202411212935.6, filed on August 30, 2024, entitled "A De-icing Device", and Chinese Patent Application No. 202422133169.6, filed on August 30, 2024, entitled "A De-icing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of new energy vehicle technology, specifically relating to a de-icing device. Background Technology

[0003] In daily life, cars are becoming increasingly common, and the widespread use of gasoline-powered vehicles not only exacerbates the consumption of non-renewable resources but also pollutes the environment with exhaust emissions. Faced with the growing imbalance between supply and demand for traditional energy sources and the severe situation of global warming, electric vehicles (EVs) have emerged as a new energy mode of transportation. Due to their advantages such as low noise, high energy efficiency, and zero mobile exhaust emissions, EVs have become one of the strategic emerging industries that many countries prioritize. However, as EVs enter the market, driving range has become a significant factor hindering their development. Drawing inspiration from the traditional method of using refueling to extend the driving range of cars, for EVs, charging depleted battery packs or directly replacing them with fully charged ones has become a key research and development direction for increasing the driving range of EVs.

[0004] Due to limitations in battery material and charging technologies, new energy vehicles require at least tens of minutes to fully charge after running out of power. For some new energy freight vehicles with large battery packs, this charging time is even longer, significantly impacting the user's driving experience. This is especially true for commercial vehicle owners, as waiting for charging means reduced working hours. The time required to replace the battery pack is much shorter than the charging time. Therefore, more and more new energy vehicles are adopting detachable battery packs for energy supply, solving the disadvantages of long charging times and inconvenience associated with fixed battery packs. Specifically, multiple locking mechanisms need to be installed on the bottom of the vehicle. The installation or removal of the battery pack is achieved by locking or unlocking the locking mechanisms and mating parts on the battery pack. Furthermore, for these new energy vehicles, due to the large weight and volume of the battery pack, specialized battery swapping equipment is required for disassembly and installation. However, in cold northern weather, especially after heavy snow or rain, the undercarriage can be covered with a thick layer of ice. This ice can also encase the locking mechanisms, affecting unlocking and causing the battery pack to be frozen to the bottom of the vehicle, making it difficult or even impossible to remove. This will greatly increase the battery swapping time for vehicles, leading to congestion at battery swapping stations.

[0005] Therefore, before replacing the battery pack, a de-icing device is needed to melt the ice layer on the locking mechanism. The speed of de-icing directly affects the time required for the entire battery swapping process, and the battery swapping time is the most critical factor determining the user's battery swapping experience. Therefore, how to design a de-icing device that can quickly melt ice has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] This application provides a de-icing device to solve the technical problem that when the ice layer on the bottom of the battery swapping vehicle freezes the battery pack locking mechanism in cold weather, the battery pack is difficult to remove or even impossible to remove, resulting in difficult battery swapping and low battery swapping efficiency.

[0007] The technical solution adopted in this application is as follows:

[0008] A de-icing device is provided for de-icing a battery swapping vehicle. The battery pack of the battery swapping vehicle is installed at the bottom of the vehicle body via a locking mechanism to facilitate quick battery swapping. The de-icing device includes a movable body and a heating unit and an air outlet unit installed on the body. The heating unit can deliver hot air to the air outlet unit. The body can move to the bottom of the vehicle body and align the air outlet unit with the locking mechanism to blow the hot air onto the locking mechanism.

[0009] By adopting the above technical solution, when de-icing the locking mechanism, the machine body is moved to the bottom of the vehicle, causing the air outlet unit to move under the drive of the machine body to align with the locking mechanism. Once the air outlet unit is aligned with the locking mechanism, hot air is supplied to the air outlet unit through the heating unit. The hot air is ejected from the air outlet unit and moves to the locking mechanism to melt the ice layer there. Since both the air outlet unit and the heating unit are installed on the machine body, their relative positions do not change during the movement of the machine body. The hot air supply from the heating unit to the air outlet unit is relatively stable, allowing the de-icing device to stably supply hot air to the locking mechanism through the air outlet unit, thereby quickly removing the ice layer at the locking mechanism. This allows the battery pack to be quickly removed from the bottom of the battery swapping vehicle, improving battery swapping efficiency.

[0010] The air outlet unit includes an air storage cavity and an air outlet. The air outlet unit has a hollow interior to form the air storage cavity. The bottom or side of the air storage cavity is connected to the heating unit. The air outlet is located at the top of the air storage cavity.

[0011] By adopting the above technical solution, since the air outlet unit is equipped with an air storage chamber, during the process of the heating unit delivering hot air to the air outlet unit, the hot air will first gather in the air storage chamber. Once the air storage chamber is full of hot air, the heating unit continues to inject hot air into the air storage chamber, causing the air pressure inside the chamber to continuously increase. Under this pressure, the hot air in the air storage chamber is ejected from the air outlet. The structure of the air outlet can be adaptively adjusted according to the structure of the locking mechanism. Regardless of the air outlet structure, the hot air in the air storage chamber can be evenly ejected from the air outlet under the action of air pressure, which helps to improve the performance of the locking mechanism. The uniformity of ice melting reduces the possibility that some areas of the locking mechanism have been completely melted while other areas still have a large amount of ice, thus helping to improve the ice melting efficiency. Furthermore, placing the air outlet at the top of the air storage chamber shortens the travel time of the hot air between the outlet and the locking mechanism, thereby reducing heat loss from the air storage outlet to the locking mechanism. This allows the hot air reaching the locking mechanism to maintain higher heat energy, further improving the ice melting efficiency of the locking mechanism. Simultaneously, it reduces the impact of airflow, air pressure, or other factors caused by the hot air traveling too long outside the air outlet unit, thus comprehensively improving the de-icing efficiency of the de-icing device.

[0012] The air storage cavity has a first air guide surface and a second air guide surface that are spaced apart. The gap between the first air guide surface and the second air guide surface forms the air outlet. The first air guide surface and the second air guide surface extend from the end near the air outlet to the end away from the air outlet in a direction that gradually moves away from each other.

[0013] By adopting the above technical solution, the hot air supplied by the heating unit to the air storage chamber moves randomly within the chamber under the action of kinetic energy, and the mutual impact between the hot air particles further complicates the direction of their movement. By setting the first and second air guide surfaces, the hot air within the air storage chamber can be guided. Under the guidance of the first and second air guide surfaces, the hot air gradually converges towards the air outlet. During this convergence, the hot air's direction is continuously adjusted by the first and second air guide surfaces, ensuring that the hot air moves towards the locking mechanism after reaching the air outlet. This reduces the probability of the hot air escaping in various directions after exiting the air outlet due to deviations in its direction of movement, thereby further improving the de-icing efficiency of the de-icing device. Furthermore, the first and second air guide surfaces extend from the end closest to the air outlet to the end furthest from the air outlet, gradually moving away from each other, thus ensuring that the space within the air storage chamber... The first and second air guide surfaces gradually narrow towards the air outlet. As the hot air in the storage chamber moves towards the air outlet under air pressure, the space within the storage chamber continuously contracts towards the air outlet, compressing the space available for the hot air. The hot air is constantly squeezed within this shrinking space. As the heating unit continuously supplies air to the storage chamber, the hot air must exit the air outlet at a faster speed to maintain pressure balance within the storage chamber. Therefore, the first and second air guide surfaces converge the hot air and enhance its kinetic energy, allowing the hot air ejected from the air outlet to move quickly to the ice layer of the locking mechanism. This shortens the travel time between the air outlet and the locking mechanism, reducing heat loss from the storage chamber to the locking mechanism and ensuring the hot air reaching the locking mechanism maintains higher heat energy, thus improving the ice-melting efficiency of the locking mechanism.

[0014] The first air guide surface and the second air guide surface are symmetrically arranged along the air outlet and are both inclined, extending from top to bottom in a direction that gradually moves away from each other; or, the first air guide surface extends horizontally, and the second air guide surface extends obliquely from the end near the air outlet to the end away from the air outlet in a direction that gradually moves away from the first air guide surface.

[0015] By adopting the above technical solution, the first air guide surface and the second air guide surface are symmetrically arranged, so that the hot air guided by the first air guide surface and the second air guide surface to the air outlet has a relatively symmetrical movement path, and converges at the air outlet and is sprayed together to the locking mechanism. The first air guide surface is set to extend in the horizontal direction, and the second air guide surface extends obliquely from the end near the air outlet to the end away from the air outlet in a direction that gradually moves away from the first air guide surface. This allows the hot air to move in the air storage cavity in the horizontal direction under the guidance of the first guide surface, and to continuously converge and compress under the action of the second air guide surface for rapid movement.

[0016] The first air guide surface and the second air guide surface each have an upwardly extending first air guide plate and second air guide plate on their adjacent sides. The first air guide plate and the second air guide plate are arranged in parallel or extend from top to bottom in a direction that gradually moves away from each other to form the air outlet.

[0017] By adopting the above technical solution, the first and second air guide plates further guide the hot air, causing the hot air ejected from the air storage chamber to move upward under their guidance. Even after leaving the air outlet, the hot air continues to move vertically upward due to inertia, reducing the probability of it dissipating in all directions and ensuring sufficient hot air reaches the locking mechanism. Furthermore, the first and second air guide plates also act as a barrier against the external environment, protecting the hot air from external air pressure and airflow during its movement through the air outlet, thus further... This ensures that the hot air can smoothly reach the locking mechanism for de-icing. Furthermore, by setting the first and second air guide plates to be parallel and upward, the hot air moves vertically upward in the air outlet. This allows the hot air to retain its inertia and continue moving vertically towards the locking mechanism after exiting the air outlet. Setting the first and second air guide plates to gradually move away from each other from top to bottom further concentrates and compresses the hot air during its movement through the air outlet. This allows the hot air exiting the air outlet to reach the locking mechanism at a faster speed, reducing the amount of heat loss during the movement of the hot air from the air outlet to the locking mechanism.

[0018] The locking mechanism has two rows, arranged on both sides of the battery pack along the length of the battery pack. Two air outlet units are correspondingly provided, each extending along the width of the body, corresponding to the two rows of locking mechanisms. The air outlet extends from one end of the air outlet unit to the other along the width of the body. Alternatively, there are multiple locking mechanisms arranged on the battery pack at preset positions, and multiple air outlets corresponding to the positions of each locking mechanism. And / or, the top of the air outlet has two air-expanding plates, which are correspondingly arranged on both sides of the air outlet and extend gradually from bottom to top in a direction that gradually moves away from each other.

[0019] By adopting the above technical solution, the two-row locking mechanism makes the connection between the battery pack and the battery swapping vehicle more stable and reliable. Two air outlet units are configured, and each unit simultaneously de-ices both rows of locking mechanisms, achieving synchronous de-icing of the locking mechanisms on both sides of the battery pack. This shortens the de-icing time for the battery swapping vehicle and significantly improves the de-icing efficiency of the device. Furthermore, since the two air outlet units correspond one-to-one with the two rows of locking mechanisms, when moving the machine body to align the air outlet units with the locking mechanisms, only one air outlet unit needs to be aligned with one row of locking mechanisms; the other air outlet unit will automatically align with the locking mechanism, eliminating the need to move the entire machine body. The alignment of the air outlet unit with the two locking mechanisms reduces the preparation time required before de-icing, further improving the de-icing efficiency of the device. Furthermore, by aligning the air outlets along the length of the battery pack, the hot air ejected from the air storage chamber can evenly supply air to the locking mechanisms located on the side of the battery pack, improving the uniformity of air supply to each locking mechanism and ensuring that the ice layer at each locking mechanism is heated evenly and melts in approximately equal time. Moreover, having multiple air outlets aligned with each locking mechanism allows for higher de-icing precision from the air outlet unit, with each outlet specifically targeting its corresponding locking mechanism. The mechanism provides air supply, improving the utilization efficiency of hot air while ensuring uniform air supply, thus increasing the de-icing efficiency of the de-icing device. Due to the installation of the air diffuser, after the hot air is ejected from the outlet, some of the hot air continues to move vertically upwards, while some, influenced by air pressure changes, tends to move diagonally. This portion of the hot air with a diagonal tendency moves along the extension direction of the air diffuser under its guidance, increasing the efficiency of the hot air operation and also helping to reduce the requirements for the outlet size design. That is, even when the outlet diameter is small, the hot air can still achieve full coverage of the ice layer at the locking mechanism under the action of the air diffuser. When the outlet... When the ice layer melts, the resulting water droplets fall downwards under their own gravity. The hot air at the air outlet has high thermal energy, which can instantly evaporate the water droplets into water vapor. The air diffuser can collect the melted water on the side of the air outlet, causing the water droplets falling on the diffuser to move along the diffuser towards the air outlet under their own gravity and quickly evaporate into water vapor under the action of the hot air. This reduces the probability of melted water dripping onto the air outlet unit or other components and interfering with the components of the de-icing device. Therefore, by setting up the air diffuser, more of the ice layer removed by the de-icing device is released in the form of water vapor, reducing the pressure on the collection and treatment of melted water.

[0020] The air storage cavity further includes a third air guide surface and a fourth air guide surface. The first air guide surface is located above the second air guide surface and extends horizontally. The end of the second air guide surface away from the air outlet is connected to the third air guide surface. The fourth air guide surface is connected between the third air guide surface and the second air guide surface. The third air guide surface extends upward from the second air guide surface. A receiving groove is formed between the second air guide plate, the second air guide surface and the third air guide surface to receive the ice water that falls after the air outlet unit delivers hot air to the locking mechanism. The receiving groove has guide holes at both ends along the width direction of the body that communicate with the outside of the body.

[0021] By adopting the above technical solution, the third and fourth air guide surfaces can guide the hot air entering the air storage chamber, allowing the hot air to move more smoothly towards the air outlet under the guidance of the third and fourth air guide surfaces, reducing the kinetic energy loss caused by the mutual impact of the hot air due to uneven movement direction; in addition, water droplets and small ice cubes after the ice melts will fall downwards, and the receiving groove formed by the second air guide plate, the second air guide surface and the third air guide surface provides a receiving platform for water droplets and ice cubes falling to the side of the air outlet. The bottom of the receiving groove is a high-heat air storage chamber, which continuously supplies heat to the receiving groove to quickly melt the ice cubes falling into the receiving groove, and discharges the melted ice water to the outside of the machine body through the guide hole, reducing the pressure of collecting and cleaning ice water, and reducing the risk of melted ice water affecting other components of the de-icing device.

[0022] The de-icing device further includes a first transmission pipe connecting the heating unit to the air storage chamber. The first transmission pipe includes a first pipe body and a first hot air transition member connecting the first pipe body to the air storage chamber. The first hot air transition member has a first hot air inlet communicating with the first pipe body and a first hot air outlet communicating with the bottom of the air storage chamber. The first hot air outlet opens upward to communicate with the bottom surface of the air storage chamber. Preferably, the first hot air inlet and the first hot air outlet are located on both sides of the first hot air transition member. The first hot air transition member has two opposing first air-gathering plates near the first hot air inlet, and the two first air-gathering plates gradually approach each other from one end of the hot air inlet to one end of the first hot air outlet. And / or, the first hot air transition member has an air-guiding plate near the first hot air outlet, and the air-guiding plate is inclined such that the cross-section of the first hot air transition member gradually increases from the end away from the first hot air outlet to the end closer to the first hot air outlet.

[0023] By adopting the above technical solution, when the heating unit delivers hot air to the air storage chamber through the first transmission pipe, the hot air inside the first pipe is transferred to the air storage chamber through the first hot air transition piece. The first hot air transition piece functions as a connection between the first pipe and the air storage chamber, improving the tightness of the connection between the first transmission pipe and the air storage chamber, effectively reducing the probability of hot air escaping during the transmission process from the heating unit to the air storage chamber, thereby improving the hot air delivery rate of the heating unit to the air outlet unit. In addition, the first hot air outlet is connected to the bottom surface of the air storage chamber, allowing the hot air entering the air storage chamber from the first hot air transition piece to gradually accumulate at the bottom of the air storage chamber and fill the air storage chamber from bottom to top before being ejected from the outlet, which helps to improve the storage stability of hot air in the air storage chamber. Furthermore, a first air concentrator is set near the first hot air inlet of the first hot air transition piece, which can concentrate the air entering the air storage chamber from the first hot air inlet. The hot air entering the first hot air transition piece acts as a converging plate. Under the action of the first converging plate, the movement space of the hot air gradually shrinks, and under the impetus of the subsequent hot air pressure, it moves rapidly towards the first hot air outlet. That is, the setting of the first converging plate accelerates the movement speed of the hot air in the first hot air transition piece, which helps to improve the hot air transmission efficiency. Since the first hot air outlet is located at the bottom of the air storage chamber, the hot air needs to undergo a change of movement direction during its movement from the first hot air inlet to the first hot air outlet. Therefore, by setting an air guide plate at the first hot air outlet, the cross-sectional area of ​​the first hot air transition piece is increased, providing more movement space for the hot air, reducing the impact of the hot air on the inner wall of the first hot air transition piece during the turning process, and at the same time, guiding and turning the hot air in the first hot air transition piece, thus improving the smoothness of the hot air discharged from the first hot air outlet from multiple directions.

[0024] The de-icing device further includes an air storage box located between the two air outlet units and a second transmission pipe connecting the heating unit and the air storage box. The air storage box receives hot air from the heating unit through the second transmission pipe, and delivers the hot air to the two air outlet units through a first air supply channel and a second air supply channel respectively connected between the air storage box and the two air outlet units, and blows the hot air out from the air outlet toward the locking mechanism. The first air supply channel and the second air supply channel are symmetrically arranged along the width direction of the body.

[0025] By adopting the above technical solution, when the heating unit supplies air to the air outlet unit, the hot air is first delivered to the air storage box through the second transmission pipe. After the air storage box is filled with hot air, the heating unit continues to supply hot air to the air storage box. Under pressure, the hot air in the air storage box is supplied to the two air outlet units through the symmetrically arranged first and second air supply channels. In this way, the temperature and speed of the hot air output by the two air outlet units to the locking mechanism are approximately equal, thereby ensuring that the de-icing rate of the two air outlet units on the locking mechanism is approximately equal. Therefore, synchronous de-icing of the locking mechanism can be achieved, reducing the probability of one locking mechanism being de-iced before the other needs to continue de-icing due to factors such as the size of the air supply and temperature difference of the air outlet unit. This minimizes the dry blowing of hot air on the de-iced locking mechanism.

[0026] The second transmission pipe includes a second pipe body and a second hot air transition member connecting the second pipe body to the air storage chamber. The second hot air transition member is disposed below the air outlet unit near the side of the heating unit and has a second hot air inlet communicating with the second pipe body and a second hot air outlet communicating with the air storage box. Preferably, the second hot air inlet and the second hot air outlet are located on both sides of the second hot air transition member. The second hot air transition member has two opposing second air concentrators near the second hot air inlet, and the two second air concentrators gradually approach each other from one end of the second hot air inlet to one end of the second hot air outlet.

[0027] By adopting the above technical solution, when the heating unit delivers hot air to the air storage box through the second transmission pipe, the hot air inside the second pipe is transferred to the air storage box via the second hot air transition piece. The second hot air transition piece functions as a connection between the second pipe and the air storage box, improving the tightness of the connection between the second transmission pipe and the air storage box, effectively reducing the probability of hot air leakage during the transmission process from the heating unit to the air storage box, thereby improving the hot air delivery rate of the heating unit to the air storage box. In addition, by placing the second hot air transition piece below the air outlet unit, it is possible to avoid the second hot air transition piece affecting the air supply from the air outlet unit to the locking mechanism. Furthermore, the second hot air inlet and the second hot air outlet are located on both sides of the second hot air transition piece, and a second air concentrator is set near the second hot air outlet. This concentrator can gather the hot air entering the second hot air transition piece from the second hot air inlet. Under the action of the second air concentrator, the movement space of the hot air gradually shrinks, and under the push of the subsequent hot air pressure, it moves quickly towards the second hot air outlet. In other words, the setting of the second air concentrator accelerates the movement speed of the hot air in the second hot air transition piece, which helps to improve the hot air transmission efficiency, reduce the heat loss during the hot air transmission process, and increase the amount of heat energy retained by the hot air delivered by the de-icing device to the locking mechanism.

[0028] The air storage box is one unit, and its two ends abut against the two air outlet units respectively along the length direction of the machine body. The air storage box is provided with a first air supply channel and a second air supply channel on both sides. Alternatively, the air storage box is two units, which are spaced apart along the width direction of the machine body. The two ends of the air storage box abut against the two air outlet units respectively along the length direction of the machine body. Each air storage box is provided with a first air supply channel and a second air supply channel on the side facing the other air storage box.

[0029] By adopting the above technical solution, setting the air storage box as one reduces the installation difficulty of the air storage box between the two air outlet units, and the two air outlet units can also play a role in cooperating and fixing the air storage box. The air storage box is provided with a first air supply channel and a second air supply channel on both sides, which increases the efficiency of hot air delivery from the air storage box to the two air outlet units, while reducing the mutual interference between the first air supply channel and the second air supply channel. Setting the air storage box as two allows the two air outlet units to simultaneously play a positioning role for the two air storage boxes, and integrates the first air supply channel and the second air supply channel between the two air outlet boxes, which facilitates the unified assembly of the first air supply channel and the second air supply channel.

[0030] The upper and lower surfaces of the body are respectively provided with an upper heat insulation plate and a lower heat insulation plate. The upper heat insulation plate includes multiple heat insulation sub-plates. There is a preset gap between two adjacent heat insulation sub-plates to avoid the air outlet. In the length direction of the body, the width of the preset gap is greater than the width of the air outlet so that the ice water falling after the air outlet blows hot air to the locking mechanism can be discharged from the gap between the air outlet and the heat insulation sub-plate.

[0031] By adopting the above technical solution, the upper heat insulation plate can block the heat emitted upwards from the air outlet unit and the air storage box, reducing heat loss upwards and minimizing thermal interference to the battery pack. It also helps maintain the thermal energy content of the hot air ejected from the air outlet, thus improving the de-icing efficiency of the de-icing device. Furthermore, the upper heat insulation plate can also support the falling melted ice and ice, preventing it from falling onto the air outlet unit, the air storage box, or other components of the de-icing device, thus preventing heat loss from the air outlet unit. After de-icing, the ice water on the upper heat insulation plate is easily collected and treated. Additionally, the pre-set gap between adjacent heat insulation plates provides space for the ice water to slide down. The lower heat insulation component can block the heat emitted downwards from the air outlet unit and the air storage box, reducing heat loss downwards.

[0032] The heating unit has a flue pipe for discharging exhaust gas. The flue pipe extends from the heating unit and is connected to the air storage chamber. A filter screen is installed inside the flue pipe to filter the exhaust gas.

[0033] By adopting the above technical solution, the exhaust pipe serves to guide and discharge the smoke generated when the heating unit produces hot air, preventing the smoke from spreading and affecting the de-icing operators. Furthermore, since the smoke generated by the heating unit during hot air production is at a high temperature, even higher than the hot air temperature, the exhaust pipe is connected to the air storage chamber. The smoke, carried by the hot air in the air storage chamber, moves towards the locking mechanism and assists in de-icing, achieving the recycling of high-temperature smoke and increasing the de-icing efficiency of the de-icing device. The filter in the exhaust pipe can filter and intercept solid particles and grease in the smoke, preventing these solid impurities from contaminating the locking mechanism or battery pack.

[0034] Along the length of the body, the body has an active end and a driven end arranged opposite to each other. The active end is subjected to a force to drive the driven end from one side of the vehicle body into the bottom of the vehicle body. The active end is provided with a vertically extending support part, and the driven end is provided with a positioning member. When the body enters the bottom of the vehicle body, the positioning member can be in a horizontal state to avoid the body of the battery swapping vehicle. When the body is completely entered into the bottom of the vehicle body and in place, the positioning member can switch to a vertical state and abut against one side of the vehicle body. The support part abuts against the other side of the vehicle body, so that the air outlet corresponds to the locking mechanism.

[0035] By adopting the above technical solution, the positioning component can engage with the side of the vehicle body after the machine body is fully inserted into the bottom of the vehicle. Once the positioning component is engaged with the vehicle body, the air outlet unit reaches the position opposite to the locking mechanism, thereby achieving precise air supply from the air outlet unit to the locking mechanism. Therefore, the operator can obtain the alignment of the air outlet unit by observing the engagement state between the positioning component and the vehicle body, eliminating the need to observe the relative position of the air outlet unit and the locking mechanism from the bottom of the vehicle body upwards. This greatly reduces the difficulty for the operator in adjusting the position of the de-icing device during de-icing operations. On the one hand, it shortens the preparation time required for position calibration of the air outlet unit before de-icing, thereby improving de-icing efficiency. On the other hand, when the positioning component is engaged with the side of the vehicle body, the air outlet unit is in the de-icing position directly opposite the locking mechanism, thus avoiding the misalignment of the air outlet unit with the locking mechanism caused by manual alignment. The locking mechanism has the potential for positional deviation, which further improves the de-icing efficiency of the de-icing device. In addition, by setting the active end and the driven end on the front and rear sides of the body respectively, and setting the support part and the positioning part on the active end and the driven end respectively, a force application position is provided for the operator to drive the body. The operator can move the body by applying the driving force to the support part, which reduces the difficulty of moving the body. In addition, the positioning part and the support part abut against the sides of the battery swapping vehicle body respectively, so that the positioning part and the support part can respectively stop the airflow from the side of the vehicle body to the bottom of the vehicle body, reduce the impact of the airflow on the hot air sprayed by the air outlet unit, improve the heat supply stability of the air outlet unit to the locking mechanism, and at the same time help reduce the diffusion of heat from the bottom of the vehicle body to the side of the vehicle body, which helps to further improve the de-icing speed of the de-icing device.

[0036] The de-icing device further includes a control mechanism connected to the positioning member. The control mechanism includes a first linkage, a second linkage, and a control member. The first end of the first linkage is rotatably connected to the positioning member, the second end of the first linkage is rotatably connected to the third end of the second linkage, and the fourth end of the second linkage is rotatably connected to the machine body. The control member is connected to the second end and the third end and can drive the position of the rotation point between the second end and the third end to change, thereby causing the first linkage and the second linkage to rotate, thus enabling the positioning member to switch between a horizontal and a vertical state.

[0037] By adopting the above technical solution, the control component can simultaneously act on the second end of the first linkage and the third end of the second linkage, driving the first and second linkages to rotate synchronously, thereby enabling the positioning component to switch between a horizontal and a vertical state. This allows the positioning component to avoid the vehicle body or cooperate with the side of the vehicle body. During this process, the first linkage and the positioning component, the second linkage and the positioning component, and the first linkage and the second linkage are all rotatably connected. This reduces the frictional resistance that the control component needs to overcome when driving the first and second linkages, making the switching of the positioning component between the horizontal and vertical states smoother. In addition, since the first and second linkages rotate synchronously and move closer to each other under the drive of the control component, the rotation speed of the positioning component, i.e., the switching speed from the horizontal to the vertical state, is accelerated. This reduces the working stroke of the control component when driving the positioning component to switch positions, which helps to optimize the structural design of the control mechanism.

[0038] An elastic reset member is provided between the positioning member and the body. The elastic reset member keeps the positioning member in a vertical position. When the control member applies a force, it can overcome the force of the elastic reset member and drive the positioning member to switch from a vertical position to a horizontal position. When the control member does not apply a force or removes the force, the force of the elastic reset member keeps the positioning member in a vertical position or switches it from a horizontal position to a vertical position.

[0039] By adopting the above technical solution, once the machine body is fully pushed into the bottom of the vehicle body, the operator only needs to remove the force applied to the control component. The positioning component will then switch from a horizontal to a vertical state under the elastic action of the elastic reset component. This eliminates the need for the operator to manually switch the positioning component from a horizontal to a vertical position, thus enabling rapid engagement between the positioning component and the side of the vehicle body. Furthermore, the elastic force of the elastic reset component can also maintain the positioning component in a vertical state. During the de-icing process of the de-icing device, the operator does not need to apply additional force to maintain the position of the positioning component, thus optimizing the user experience of the de-icing device.

[0040] The first linkage, the second linkage, and the control component are each provided in pairs, symmetrically arranged at both ends of the positioning component along the length direction of the vehicle body. The control mechanism also includes a synchronous shaft, which is connected to the end of the two control components away from the rotation point. The control mechanism also includes a control rod and two third linkages, which are arranged at both ends of the synchronous shaft along the width direction of the vehicle body and respectively connected to the control components at the corresponding ends. The control rod is fixed to the synchronous shaft.

[0041] By adopting the above technical solution, the number of the first linkage, the second linkage, and the control component is set to two, and they are respectively located at both ends of the positioning component. This makes the rotational force applied to the positioning component more uniform, reducing the force pressure required for a single control component to drive the positioning component to rotate. Furthermore, since a synchronous shaft is provided, and both control components are connected to the synchronous shaft, the operator only needs to apply force to the synchronous shaft. The synchronous shaft rotates, simultaneously driving both control components to move, thereby driving the first and second linkage components located on both sides of the positioning component. This eliminates the need to simultaneously drive both control components, reducing the operator's workload and optimizing the structural design of the de-icing device. Moreover, since the end of the third linkage component away from the synchronous shaft is connected to the control component, only a small rotation angle of the synchronous shaft is needed to drive the end of the third linkage component away from the synchronous shaft to achieve a large stroke. This allows for a larger stroke change in the control component connected to the third linkage component, which in turn drives the first linkage component to rotate. The first linkage and the second linkage drive the positioning component to move; that is, the positioning component can be switched from a vertical state to a horizontal state by a small amount of rotation of the synchronous shaft. This reduces the working space required for the control mechanism to move the positioning component, which helps to miniaturize the de-icing device. At the same time, the operator only needs a small force stroke to move the positioning component to a horizontal state, which optimizes the structural design of the de-icing device. Furthermore, since the rotation trajectory of the synchronous shaft is fixed, the synchronous rotation trajectory of the third linkage is also fixed, which ensures that the movement trajectory of the control component connected to the third linkage is constant. Therefore, by rotating the synchronous shaft, the movement of the two control components along a fixed trajectory can be realized to drive the positioning component to switch from a vertical state to a horizontal state. This avoids the phenomenon of force deviation of the control component on the first and second linkage components caused by operator force deviation or other factors, and provides a guarantee for the stability of the positioning component during the switching process from a vertical state to a horizontal state.

[0042] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0043] During de-icing of the locking mechanism, the machine body is moved to the bottom of the vehicle, causing the air outlet unit to move to a position aligned with the locking mechanism. Once aligned, the air outlet unit delivers hot air to the air outlet unit via the heating unit. The hot air is ejected from the air outlet unit and travels to the locking mechanism to melt the ice layer there. Since both the air outlet unit and the heating unit are mounted on the machine body, their relative positions do not change during the machine body's movement. The hot air delivery from the heating unit to the air outlet unit is relatively stable, allowing the de-icing device to stably deliver hot air to the locking mechanism through the air outlet unit. This quickly removes the ice layer from the locking mechanism, enabling the battery pack to be quickly removed from the bottom of the battery swapping vehicle, improving battery swapping efficiency.

[0072] As shown in Figures 1, 5, 9, 10, 13, and 19 to 21, a de-icing device is used to de-ice a battery swapping vehicle. The battery pack of the battery swapping vehicle is installed at the bottom of the vehicle body via a locking mechanism 210 to facilitate quick battery pack swapping. The de-icing device includes a movable body 1 and a heating unit 2 and an air outlet unit 3 installed on the body 1. The heating unit 2 can deliver hot air to the air outlet unit 3. The body 1 can move to the bottom of the battery swapping vehicle body and align the air outlet unit 3 with the locking mechanism 210 to blow hot air to the locking mechanism 210.

[0073] In Figure 20, arrow Y indicates the length of the battery swapping vehicle 220, and arrow X indicates the direction of movement of the de-icing device into the bottom of the battery swapping vehicle 220. The body 1 enters the bottom of the battery swapping vehicle 220 along the side of the vehicle. When de-icing the locking mechanism 210, the body 1 is moved to the bottom of the vehicle, so that the air outlet unit 3 moves to the position aligned with the locking mechanism 210 under the drive of the body 1. After the air outlet unit 3 is aligned with the locking mechanism 210, hot air is delivered to the air outlet unit 3 through the heating unit 2. The hot air is sprayed out from the air outlet unit 3 and moves to the locking mechanism 210 to achieve thermal melting of the ice layer at the locking mechanism 210. Since both the air outlet unit 3 and the heating unit 2 are installed on the body 1, their relative positions will not change during the movement of the body 1. The heating unit 2 delivers hot air to the air outlet unit 3 in a relatively stable manner, which allows the de-icing device to deliver hot air to the locking mechanism 210 through the air outlet unit 3, thereby quickly removing the ice layer at the locking mechanism 210 and enabling the battery pack to be quickly removed from the bottom of the battery swapping vehicle, thus improving the battery swapping efficiency.

[0074] Optionally, the bottom of the fuselage 1 is provided with casters 15, and the side of the fuselage 1 away from the vehicle body is also provided with a handrail 14, so that the operator can push and pull the fuselage 1 into and out of the bottom of the vehicle body through the handrail 14.

[0075] As an optional embodiment of this application, as shown in Figures 2 to 4, the air outlet unit 3 includes an air storage cavity 31 and an air outlet 32. The air outlet unit 3 has a hollow interior to form the air storage cavity 31. The bottom or side of the air storage cavity 31 is connected to the heating unit 2, and the air outlet 32 ​​is located at the top of the air storage cavity 31.

[0076] Since the air outlet unit 3 is equipped with an air storage cavity 31, during the process of the heating unit 2 supplying hot air to the air outlet unit 3, the hot air will first gather in the air storage cavity 31. After the air storage cavity 31 is full of hot air, as the heating unit 2 continues to inject hot air into the air storage cavity 31, the air pressure inside the air storage cavity 31 continuously increases. Under the action of pressure, the hot air inside the air storage cavity 31 is ejected from the air outlet 32. The structure of the air outlet 32 ​​can be adaptively adjusted according to the structure of the locking mechanism. Regardless of the structure of the air outlet 32, the hot air inside the air storage cavity 31 can be evenly ejected from the air outlet 32 ​​under the action of air pressure, which helps to improve the efficiency of heating. The uniformity of ice melting in the locking mechanism reduces the possibility that some areas of the locking mechanism have been melted while other areas still have a large amount of ice, thus helping to improve the ice melting efficiency. Furthermore, placing the air outlet 32 ​​at the top of the air storage chamber 31 shortens the travel time of the hot air between the air outlet 32 ​​and the locking mechanism, thereby helping to reduce the heat loss of the hot air from the air storage chamber to the locking mechanism. This allows the hot air reaching the locking mechanism to maintain higher heat energy, which helps to improve the ice melting efficiency of the locking mechanism. At the same time, it reduces the impact of airflow, air pressure, or other factors caused by the hot air traveling too long outside the air outlet unit 3, thus improving the de-icing efficiency of the de-icing device in multiple ways.

[0077] As an optional embodiment of this implementation, as shown in Figures 2 to 5, the air storage cavity 31 has a first air guide surface 33 and a second air guide surface 34 arranged at intervals. The gap between the first air guide surface 33 and the second air guide surface 34 forms an air outlet 32. The first air guide surface 33 and the second air guide surface 34 extend from the end near the air outlet 32 ​​to the end away from the air outlet 32 ​​in a direction that gradually moves away from each other.

[0078] Because the hot air supplied by the heating unit 2 to the air storage chamber 31 moves randomly within the air storage chamber 31 under the action of kinetic energy, and the mutual impact between the hot air gusts makes the direction of the hot air movement even more chaotic, by setting the first air guide surface 33 and the second air guide surface 34, the hot air in the air storage chamber 31 can be guided. Under the guidance of the first air guide surface 33 and the second air guide surface 34, the hot air gradually converges towards the air outlet 32, and during the process of the hot air converging towards the air outlet 32, it is influenced by the first air guide surface 33 and the second air guide surface 34. The second air guide surface 34 continuously adjusts its direction of movement, ensuring that the hot air moves towards the locking mechanism after reaching the air outlet 32. This reduces the probability of the hot air escaping in all directions after exiting the air outlet 32 ​​due to deviation in the direction of movement, thereby further improving the de-icing efficiency of the de-icing device. Furthermore, the first air guide surface 33 and the second air guide surface 34 extend from the end closest to the air outlet 32 ​​towards the end furthest from the air outlet 32, gradually moving away from each other. This ensures that the space within the air storage cavity 31 corresponds to the first... The air guide surface 33 and the second air guide surface 34 continuously tighten towards the air outlet 32. As the hot air in the air storage cavity 31 moves towards the air outlet 32 ​​under the action of air pressure, the space left for the hot air to move is continuously compressed because the space in the air storage cavity 31 is continuously narrowing towards the air outlet 32. The hot air is continuously squeezed in the gradually shrinking space. As the heating unit 2 continues to supply air to the air storage cavity 31, the hot air must be discharged from the air outlet 32 ​​at a faster speed to maintain the air pressure in the air storage cavity 31. Balance; therefore, the arrangement of the first air guide surface 33 and the second air guide surface 34 has the effect of converging the hot air and enhancing the kinetic energy of the hot air movement, so that the hot air ejected from the air outlet 32 ​​can move quickly to the ice layer of the locking mechanism at a faster speed, shortening the movement time of the hot air between the air outlet 32 ​​and the locking mechanism, thereby helping to reduce the heat dissipation of the hot air from the air storage port to the locking mechanism, so that the hot air arriving at the locking mechanism can maintain a higher heat energy, which helps to improve the ice melting efficiency of the locking mechanism.

[0079] This embodiment does not limit the structural form of the first air guide surface 33 and the second air guide surface 34. They can be planes as shown in Figures 2 to 5. In another embodiment, they can also be arc surfaces that are concave or convex towards the air storage cavity 31.

[0080] This embodiment does not limit the positional relationship between the first air guide surface 33 and the second air guide surface 34, and it can adopt any of the following examples:

[0081] Example 1: As shown in Figure 3, the first air guide surface 33 and the second air guide surface 34 are symmetrically arranged along the air outlet 32 ​​and are both inclined, extending gradually from top to bottom in a direction that gradually moves away from each other. The symmetrical arrangement of the first air guide surface 33 and the second air guide surface 34 ensures that the hot air guided by the first air guide surface 33 and the second air guide surface 34 to the air outlet 32 ​​has a relatively symmetrical movement path, converging at the air outlet 32 ​​and being sprayed together onto the locking mechanism.

[0082] Example 2: As shown in Figure 4, the first air guide surface 33 extends horizontally, and the second air guide surface 34 extends obliquely from the end near the air outlet 32 ​​to the end away from the air outlet 32, gradually moving away from the first air guide surface 33. By setting the first air guide surface 33 to extend horizontally and the second air guide surface 34 to extend obliquely from the end near the air outlet 32 ​​to the end away from the air outlet 32, the hot air moves horizontally under the guidance of the first air guide surface in the air storage cavity 31, and continuously converges and compresses under the action of the second air guide surface 34 for rapid movement.

[0083] Optionally, as shown in Figures 3 and 4, the first air guide surface 33 and the second air guide surface 34 have an upwardly extending first air guide plate 35 and second air guide plate 36 on the adjacent side, and the first air guide plate 35 and the second air guide plate 36 are arranged in parallel or gradually extend from top to bottom in a direction that gradually moves away from each other to form an air outlet 32.

[0084] The first air guide plate 35 and the second air guide plate 36 further guide the hot air, causing the hot air ejected from the air storage chamber 31 to move upward under the guidance of the first air guide plate 35 and the second air guide plate 36. After the hot air leaves the air outlet 32, it can still move vertically upward under the action of inertia, thereby reducing the probability of the hot air escaping to the surroundings after leaving the air outlet 32, and ensuring that the amount of hot air reaches the locking mechanism. In addition, the first air guide plate 35 and the second air guide plate 36 also block the hot air from the external environment, so that the hot air is not affected by the external air pressure and airflow during its movement at the air outlet 32, thereby further guiding the hot air. The first air guide plate 35 and the second air guide plate 36 are set to be parallel to each other upwards, so that the hot air moves vertically upwards in the air outlet 32. This ensures that the hot air still has the inertia to move vertically towards the locking mechanism after being ejected from the air outlet 32. The first air guide plate 35 and the second air guide plate 36 are set to gradually move away from each other from top to bottom, so that the hot air is further converged and compressed during its movement in the air outlet 32. This allows the hot air ejected from the air outlet 32 ​​to reach the locking mechanism at a faster speed, reducing the amount of heat energy lost during the movement of the hot air from the air outlet 32 ​​to the locking mechanism.

[0085] This embodiment does not limit the structural form of the locking mechanism and the air outlet 32, and they can adopt any of the following embodiments:

[0086] Example 1: As shown in Figures 1, 2, and 21, there are two rows of locking mechanisms 210, which are arranged on both sides of the battery pack along the length of the battery pack. There are two air outlet units 3. The two air outlet units 3 are respectively arranged along the width of the body 1, corresponding to the two rows of locking mechanisms 210. The air outlet 32 ​​extends from one end of the air outlet unit 3 to the other end along the width of the body 1.

[0087] The air outlet 32 ​​extends from one end of the air outlet unit 3 to the other end along the length of the battery pack. By setting the air outlet 32 ​​to extend along the length of the battery pack, the hot air ejected from the air storage chamber 31 can provide uniform air supply to the locking mechanism 210 located on the side of the battery pack along its length, thereby improving the uniformity of air supply to each locking mechanism 210 by the de-icing device, and ensuring that the ice layer at each locking mechanism 210 is heated uniformly and the ice melting time is approximately equal.

[0088] In this embodiment, the air outlet 32 ​​is suitable when the locking mechanisms 210 on the side of the battery pack are densely distributed or when the locking mechanisms 210 are strip-shaped structures extending along the length of the battery pack. The distance between each locking mechanism 210 along the length of the battery pack is short. By supplying air to multiple densely arranged locking mechanisms 210 through the air outlet 32 ​​extending along the length of the battery pack, it helps to simplify the structural design of the air outlet 32 ​​and reduce the manufacturing difficulty of the air outlet 32.

[0089] Example 2: Multiple locking mechanisms are installed on the battery pack at preset positions, and multiple air outlets correspond to the positions of each locking mechanism. This type of locking mechanism allows for diverse arrangements that can be tailored to specific needs. For instance, Chinese Patent Application Publication No. CN106080159A discloses one such arrangement. When the locking mechanism is frozen by ice and snow in winter, the de-icing device of this example can be used to blow hot air onto the locking mechanism to remove the ice and snow.

[0090] The air outlet in this embodiment is suitable when the locking mechanisms on the side of the battery pack are sparsely distributed, that is, when the distance between each locking mechanism is long. By setting up a one-to-one corresponding air outlet, air is supplied to each locking mechanism for de-icing, reducing the heat loss caused by ineffective air supply to areas where no locking mechanism is set.

[0091] Example 3: As shown in Figures 2 to 4, the top of the air outlet 32 ​​is provided with two air expansion plates 37, which are respectively arranged on both sides of the air outlet 32 ​​and gradually extend from bottom to top in a direction that gradually moves away from each other.

[0092] Because of the expansion plate 37, after the hot air is ejected from the outlet 32, part of the hot air continues to move vertically upwards, while part of the hot air tends to move obliquely due to changes in air pressure. This part of the hot air with the oblique tendency moves along the extension direction of the expansion plate 37 under its guidance, which increases the working efficiency of the hot air and also helps to reduce the design requirements of the outlet 32 ​​size. That is, when the diameter of the outlet 32 ​​is small, the hot air can still achieve full coverage of the ice layer at the locking mechanism under the action of the expansion plate 37. In addition, when the ice layer above the outlet 32 ​​melts, the melted water droplets will... Water droplets fall downwards under the influence of gravity, while the hot air at the air outlet 32 ​​has high thermal energy, which can instantly evaporate the water droplets into water vapor. The air diffuser 37 can collect the melted water on the side of the air outlet 32, so that the water droplets falling on the air diffuser 37 move along the air diffuser 37 towards the air outlet 32 ​​under their own gravity and are quickly evaporated into water vapor under the action of hot air. This reduces the probability of melted water dripping onto the air outlet unit 3 or other components and interfering with the components of the de-icing device. Therefore, by setting the air diffuser 37, more of the ice layer removed by the de-icing device is released in the form of water vapor, reducing the pressure on the collection and treatment of melted water.

[0093] Based on the above Example 2, optionally, as shown in Figures 4 to 6, the air storage cavity 31 further includes a third air guide surface 38 and a fourth air guide surface 39. The first air guide surface 33 is located above the second air guide surface 34 and extends horizontally. The end of the second air guide surface 34 away from the air outlet 32 ​​is connected to the third air guide surface 38. The fourth air guide surface 39 is connected between the third air guide surface 38 and the second air guide surface 34. The third air guide surface 38 extends upward from the second air guide surface 34. A receiving groove 4 is formed between the second air guide plate 36, the second air guide surface 34 and the third air guide surface 38 to receive the ice water that falls after the air outlet unit 3 delivers hot air to the locking mechanism. The receiving groove 4 has guide holes 41 at both ends along the width direction of the body 1 that communicate with the outside of the body 1. The fourth air guide surface 39 can be set at an angle and directly connected between the second air guide surface 34 and the third air guide surface 38; or, the fourth air guide surface 39 can be L-shaped as shown in Figure 7, with its lower end connected to the second air guide surface 34 and its upper end connected to the third air guide surface 38.

[0094] The third air guide surface 38 and the fourth air guide surface 39 guide the hot air entering the air storage cavity 31, allowing the hot air to move more smoothly towards the air outlet 32 ​​under their guidance, reducing the kinetic energy loss caused by the mutual impact of the hot air due to uneven movement direction. In addition, water droplets and small ice cubes after the ice melts will fall downwards. The receiving groove 4 formed by the second air guide plate 36, the second air guide surface 34 and the third air guide surface 38 provides a receiving platform for water droplets and ice cubes falling to the side of the air outlet 32. The bottom of the receiving groove 4 is the high-heat air storage cavity 31. The air storage cavity 31 continuously supplies heat to the receiving groove 4 to quickly melt the ice cubes falling into the receiving groove 4, and discharges the melted ice water to the outside of the machine body 1 through the guide hole 41, reducing the pressure on the collection and cleaning of ice water and reducing the risk of the melted ice water affecting other components of the de-icing device.

[0095] Furthermore, two vertical plates 18 are provided at both ends along the extension direction of the receiving groove 4. The second air guide plate 36, the second air guide surface 34 and the third air guide surface 38 all abut against the vertical plates 18. The vertical plates 18 are provided with guide holes 41.

[0096] As an optional embodiment of this application, as shown in Figures 5, 7, and 8, the de-icing device further includes a first transmission pipe 6 that connects the heating unit 2 to the air storage chamber 31. The first transmission pipe 6 includes a first pipe body 61 and a first hot air transition member 62 that connects the first pipe body 61 to the air storage chamber 31. The first hot air transition member 62 has a first hot air inlet 621 that connects to the first pipe body 61 and a first hot air outlet 622 that connects to the bottom of the air storage chamber 31. The first hot air outlet 622 opens upwards to connect with the bottom surface of the air storage chamber 31.

[0097] When the heating unit 2 delivers hot air to the air storage cavity 31 through the first transmission pipe 6, the hot air in the first pipe body 61 is transmitted to the air storage cavity 31 through the first hot air transition piece 62. The first hot air transition piece 62 serves to connect the first pipe body 61 and the air storage cavity 31, improving the tightness of the connection between the first transmission pipe 6 and the air storage cavity 31, effectively reducing the probability of hot air escaping during the transmission process from the heating unit 2 to the air storage cavity 31, thereby improving the hot air delivery rate of the heating unit 2 to the air outlet unit 3. In addition, the first hot air outlet 622 is connected to the bottom surface of the air storage cavity 31, so that the hot air entering the air storage cavity 31 from the first hot air transition piece 62 can gradually accumulate at the bottom of the air storage cavity 31 and fill the air storage cavity 31 from bottom to top before being sprayed out from the air outlet 32, which helps to improve the storage stability of hot air in the air storage cavity 31.

[0098] As an optional embodiment of this implementation, as shown in FIG8, the first hot air inlet 621 and the first hot air outlet 622 are located on both sides of the first hot air transition member 62. The first hot air transition member 62 is provided with two opposing first air concentrators 623 near the first hot air inlet 621. The two first air concentrators 623 gradually approach each other from one end of the hot air inlet to one end of the first hot air outlet 622.

[0099] A first concentrator 623 is provided near the first hot air inlet 621 in the first hot air transition member 62. It can concentrate the hot air entering the first hot air transition member 62 from the first hot air inlet 621. Under the action of the first concentrator 623, the movement space of the hot air gradually shrinks, and under the push of the subsequent hot air pressure, it moves quickly towards the first hot air outlet 622. That is, the setting of the first concentrator 623 accelerates the movement speed of the hot air in the first hot air transition member 62, which helps to improve the hot air transmission efficiency.

[0100] As another optional embodiment of this implementation, as shown in FIG8, the first hot air transition member 62 is provided with an air guide plate 624 near the first hot air outlet 622. The air guide plate 624 is inclined so that the cross section of the first hot air transition member 62 gradually increases from the end away from the first hot air outlet 622 toward the end near the first hot air outlet 622.

[0101] Since the first hot air outlet 622 is located at the bottom of the air storage cavity 31, the hot air needs to undergo a change in direction of movement during its movement from the first hot air inlet 621 to the first hot air outlet 622. Therefore, by setting an air guide plate 624 at the first hot air outlet 622, the cross-sectional area of ​​the first hot air transition piece 62 is increased, providing more space for the hot air to move and reducing the impact of the hot air on the inner wall of the first hot air transition piece 62 during the turning process. At the same time, it plays a guiding and turning role for the hot air in the first hot air transition piece 62, thereby improving the smoothness of the hot air discharged from the first hot air outlet 622 in multiple ways.

[0102] As another optional embodiment of this application, as shown in Figures 9 and 10, the de-icing device further includes an air storage box 9 located between the two air outlet units 3 and a second transmission pipe 7 connecting the heating unit 2 and the air storage box 9. The air storage box 9 receives hot air from the heating unit 2 through the second transmission pipe 7, and delivers the hot air to the two air outlet units 3 through the first air supply channel 91 and the second air supply channel 92 respectively connected between the air storage box 9 and the two air outlet units 3, and blows it out from the air outlet 32 ​​to the locking mechanism. The first air supply channel 91 and the second air supply channel 92 are symmetrically arranged along the width direction of the body 1.

[0103] When the heating unit 2 supplies air to the air outlet unit 3, the hot air is first delivered to the air storage box 9 through the second transmission pipe 7. After the air storage box 9 is filled with hot air, the heating unit 2 continues to supply hot air to the air storage box 9. Under pressure, the hot air in the air storage box 9 is supplied to the two air outlet units 3 through the symmetrically arranged first air supply channel 91 and second air supply channel 92. In this way, the temperature and speed of the hot air output by the two air outlet units 3 to the locking mechanism are approximately equal, thereby ensuring that the de-icing rate of the two air outlet units 3 on the locking mechanism is approximately equal. Therefore, synchronous de-icing of the locking mechanism can be achieved, reducing the probability of one locking mechanism being de-iced and the other needing to continue de-icing due to factors such as the size of the air supply and temperature difference of the air outlet unit 3. This minimizes the dry blowing of hot air on the de-iced locking mechanism.

[0104] As an optional embodiment of this implementation, as shown in Figures 9 to 12, the second transmission pipe 7 includes a second pipe body 71 and a second hot air transition member 72 that connects the second pipe body 71 to the air storage chamber 31. The second hot air transition member 72 is disposed below the air outlet unit 3 near the side of the heating unit 2 and has a second hot air inlet 721 that communicates with the second pipe body 71 and a second hot air outlet 722 that communicates with the air storage box 9.

[0105] When the heating unit 2 delivers hot air to the air storage box 9 through the second transmission pipe 7, the hot air in the second pipe 71 will be transmitted to the air storage box 9 through the second hot air transition piece 72. The second hot air transition piece 72 serves to connect the second pipe 71 and the air storage box 9, improving the tightness of the connection between the second transmission pipe 7 and the air storage box 9, effectively reducing the probability of hot air escaping during the transmission process from the heating unit 2 to the air storage box 9, thereby improving the hot air delivery rate of the heating unit 2 to the air storage box 9. In addition, by setting the second hot air transition piece 72 below the air outlet unit 3, it is possible to avoid the second hot air transition piece 72 affecting the air supply from the air outlet unit 3 to the locking mechanism.

[0106] As an optional example of this embodiment, as shown in FIG12, the second hot air inlet 721 and the second hot air outlet 722 are located on both sides of the second hot air transition member 72. The second hot air transition member 72 is provided with two opposing second air concentrators 723 near the second hot air inlet 721. The two second air concentrators 723 gradually approach each other from one end of the second hot air inlet 721 to one end of the second hot air outlet 722. The second hot air inlet 721 and the second hot air outlet 722 are located on both sides of the second hot air transition member 72, and a second air concentrator 723 is provided near the second hot air outlet 722. This concentrator can gather the hot air entering the second hot air transition member 72 from the second hot air inlet 721. Under the action of the second air concentrator 723, the movement space of the hot air gradually shrinks, and under the push of the subsequent hot air pressure, it moves quickly towards the second hot air outlet 722. That is, the setting of the second air concentrator 723 accelerates the movement speed of the hot air in the second hot air transition member 72, which helps to improve the hot air transmission efficiency, reduce the heat loss during the hot air transmission process, and increase the heat energy retention of the hot air delivered by the de-icing device to the locking mechanism.

[0107] This example does not limit the number or installation method of the air storage boxes 9, which can be adopted in any of the following ways:

[0108] Method 1: As shown in Figure 9, there is one air storage box 9. Along the length of the body 1, both ends of the air storage box 9 abut against two air outlet units 3 respectively. The air storage box 9 has a first air supply channel 91 and a second air supply channel 92 on both sides. Setting the air storage box 9 as a single unit reduces the installation difficulty of the air storage box 9 between the two air outlet units 3, and the two air outlet units 3 can also play a role in fixing the air storage box 9. The first air supply channel 91 and the second air supply channel 92 on both sides of the air storage box 9 increase the efficiency of hot air delivery from the air storage box 9 to the two air outlet units 3, while reducing the mutual interference between the first air supply channel 91 and the second air supply channel 92.

[0109] Method 2: As shown in Figure 10, there are two air storage boxes 9, which are spaced apart along the width of the body 1. Each air storage box 9 abuts against two air outlet units 3 at both ends along the length of the body 1. Each air storage box 9 has a first air supply channel 91 and a second air supply channel 92 on the side facing the other air storage box 9. By setting two air storage boxes 9, the two air outlet units 3 can simultaneously position the two air storage boxes 9. Integrating the first air supply channel 91 and the second air supply channel 92 between the two air outlet boxes facilitates the unified assembly of the first air supply channel 91 and the second air supply channel 92.

[0110] Furthermore, as shown in Figure 10, the body 1 is provided with a partition plate 19 at the corresponding air storage box 9. The partition plate divides the body 1 into a first installation area 16 and a second installation area 17. Two air supply boxes and a first air supply channel 91 and a second air supply channel 92 connected to them are respectively installed in the first installation area 16 and the second installation area 17.

[0111] Based on Method 1 and Method 2, further as shown in Figures 1 and 2, the upper and lower surfaces of the body 1 are respectively provided with an upper heat insulation plate 5 and a lower heat insulation plate. The upper heat insulation plate 5 includes multiple heat insulation sub-plates 51. There is a preset gap between two adjacent heat insulation sub-plates 51 corresponding to the air outlet unit 3 to avoid the air outlet 32. In the length direction of the body 1, the width of the preset gap is greater than the width of the air outlet 32 ​​so that the ice water falling after the air outlet 32 ​​blows hot air to the locking mechanism can be discharged from the gap between the air outlet 32 ​​and the heat insulation sub-plate 51.

[0112] The upper heat insulation plate 5 can block the heat dissipated upwards by the air outlet unit 3 and the air storage box 9, reducing the heat loss upwards from the air outlet unit 3 and the air storage box 9, reducing the thermal interference of the air outlet unit 3 and the air storage box 9 on the battery pack, while helping to maintain the thermal energy content of the hot air ejected from the air outlet 32, thereby helping to improve the de-icing efficiency of the de-icing device; in addition, the upper heat insulation plate 5 can also bear the ice melt water and ice blocks falling from above, preventing ice water from falling onto the air outlet unit 3 and the air storage box 9 or other components of the de-icing device, preventing the dripping ice water from causing heat loss to the air outlet unit 3. At the same time, after the de-icing work is completed, the ice water that falls on the upper heat insulation plate 5 is also easy to collect and treat; in addition, the preset gap between the two adjacent heat insulation sub-plates 51 also provides space for ice water to slide down, so that the ice water... The lower insulation component can block the heat dissipated downwards by the air outlet unit 3 and the air storage box 9, thus slowing down the heat loss downwards from the air outlet unit 3 and the air storage box 9.

[0113] This application does not limit the structural form of the upper heat insulation plate 5. In another embodiment, the upper heat insulation plate 5 can also be an integral plate structure with a windproof gap at the position corresponding to the air outlet unit 3. When the upper heat insulation plate 5 is installed on the upper surface of the body 1, the windproof gap is opposite to the air outlet unit 3.

[0114] Optionally, the projection of the lower insulation plate along the vertical direction covers the air storage box 9 and the air outlet unit 3.

[0115] Optionally, as shown in Figures 5 and 18, the heating unit 2 has a flue pipe 8 for discharging exhaust gas. The flue pipe 8 extends from the heating unit 2 and connects to the air storage chamber 31. A filter screen is installed inside the flue pipe 8 to filter the exhaust gas. The flue pipe 8 serves to guide the exhaust of the smoke generated when the heating unit 2 generates hot air, preventing the smoke from spreading and affecting the de-icing operators. In addition, since the smoke generated by the heating unit 2 when generating hot air is at a high temperature, even higher than the temperature of the hot air, the flue pipe 8 is connected to the air storage chamber 31. The smoke moves towards the locking mechanism under the influence of the hot air in the air storage chamber 31, which helps to melt the ice and realizes the recycling of high-temperature smoke, increasing the de-icing efficiency of the de-icing device. The filter screen in the flue pipe 8 can filter and intercept solid particles, grease, etc. in the smoke, preventing these solid impurities from contaminating the locking mechanism or battery pack.

[0116] Furthermore, the heating unit 2 can be a diesel heater. Diesel heaters have a simple structure, strong adaptability, and good heating effect. However, when a diesel heater is working, it may produce high-temperature exhaust gas containing solid particles such as soot and carbon deposits. This high-temperature exhaust gas is transmitted to the air storage chamber 31 through the exhaust pipe 8, and the high-temperature exhaust gas is used to assist in melting ice on the locking mechanism.

[0117] As an optional embodiment of this application, as shown in FIG13, along the length direction of the body 1, the body 1 has an active end 11 and a driven end 12 arranged opposite to each other. The active end 11 is driven by an applied force to drive the driven end 12 from one side of the vehicle body into the bottom of the vehicle body. The active end 11 is provided with a vertically extending support part 13, and the driven end 12 is provided with a positioning member 100. When the body 1 enters the bottom of the vehicle body, the positioning member 100 can be in a horizontal state to avoid the body of the battery swapping vehicle. When the body 1 is completely entered into the bottom of the vehicle body and in place, the positioning member 100 can be switched to a vertical state and abut against one side of the vehicle body. The support part 13 abuts against the other side of the vehicle body, so that the air outlet 32 ​​corresponds to the locking mechanism.

[0118] The positioning component 100 engages with the side of the vehicle body after the body 1 is fully inserted into the bottom of the vehicle. Once engaged, the air outlet unit 3 reaches a position opposite to the locking mechanism, achieving precise air supply from the air outlet unit 3 to the locking mechanism. Therefore, operators can determine the alignment of the air outlet unit 3 by observing the engagement of the positioning component 100 with the vehicle body, eliminating the need to observe the relative position of the air outlet unit 3 and the locking mechanism from the bottom of the vehicle. This significantly reduces the difficulty of adjusting the position of the de-icing device during de-icing operations. On one hand, it shortens the preparation time required for position calibration of the air outlet unit 3 before de-icing, thereby improving de-icing efficiency. On the other hand, when the positioning component 100 engages with the side of the vehicle body, the air outlet unit 3 is in a de-icing position directly opposite the locking mechanism, thus avoiding positional deviations between the air outlet unit 3 and the locking mechanism caused by manual alignment. This increases the possibility of further improving the de-icing efficiency of the de-icing device. In addition, by setting the active end 11 and the driven end 12 on the front and rear sides of the body 1 respectively, and setting the bearing part 13 and the positioning part 100 on the active end 11 and the driven end 12 respectively, the operator can apply force to the body 1. The operator can move the body 1 by applying the driving force to the bearing part 13, which reduces the difficulty of moving the body 1. In addition, the positioning part 100 and the bearing part 13 abut against the sides of the vehicle body, so that the positioning part 100 and the bearing part 13 can respectively stop the airflow from the side of the vehicle body to the bottom of the vehicle body, reduce the impact of the airflow on the hot air sprayed by the air outlet unit 3, improve the heating stability of the air outlet unit 3 to the locking mechanism, and at the same time help reduce the diffusion of heat from the bottom of the vehicle body to the side of the vehicle body, which helps to further improve the de-icing speed of the de-icing device.

[0119] Optionally, the heating unit 2 is installed inside the support portion 13.

[0120] As an optional embodiment of this implementation, as shown in FIG14, the de-icing device further includes a control mechanism connected to the positioning member 100. The control mechanism includes a first linkage 110, a second linkage 120, and a control member 130. The first end 1101 of the first linkage 110 is rotatably connected to the positioning member 100, the second end 1102 of the first linkage 110 is rotatably connected to the third end 1201 of the second linkage 120, and the fourth end 1202 of the second linkage 120 is rotatably connected to the body 1. The control member 130 is connected to the second end 1102 and the third end 1201 and can drive the position of the rotation point between the second end 1102 and the third end 1201 to change, so that the first linkage 110 and the second linkage 120 rotate, thereby enabling the positioning member 100 to switch between a horizontal state and a vertical state.

[0121] The control element 130 can simultaneously act on the second end 1102 of the first linkage 110 and the third end 1201 of the second linkage 120, causing the first linkage 110 and the second linkage 120 to rotate synchronously, thereby enabling the positioning element 100 to switch between a horizontal and a vertical state, so as to achieve the positioning element 100's avoidance of the vehicle body or its cooperation with the side of the vehicle body; in this process, the first linkage 110 and the positioning element 100, the second linkage 120 and the positioning element 100, and the first linkage 110 and the second linkage 120 are all rotatably connected, thus reducing the control... The frictional resistance that the first linkage 110 and the second linkage 120 need to overcome during the movement of the component 130 makes the switching of the positioning component 100 between the horizontal and vertical states smoother. In addition, since the first linkage 110 and the second linkage 120 rotate synchronously and move closer to each other under the drive of the control component 130, the rotation speed of the positioning component 100, that is, the switching speed from the horizontal state to the vertical state, is accelerated, thereby reducing the working stroke of the control component 130 when driving the positioning component 100 to switch positions, which helps to optimize the structural design of the control mechanism.

[0122] Optionally, the air outlet unit 3 extends along the width direction of the body 1 and neither end of the body 1 extends beyond the positioning member 100 in the width direction. This allows the positioning member 100 to provide maximum shielding of the side space of the air outlet unit 3, improving the shielding effect of the positioning member 100 on airflow, debris, etc. from the side of the vehicle body, and significantly improving the stability of the hot air output of the air outlet unit 3.

[0123] Optionally, as shown in Figure 14, the positioning member 100 is provided with a flexible anti-collision pad 1001 on the side facing the vehicle body. When the positioning member 100 switches from a horizontal state to a vertical state, the flexible anti-collision pad 1001 can absorb the impact force between the positioning member 100 and the side of the vehicle body caused by the rotation of the positioning member 100, reduce the kinetic energy impact on the side of the vehicle body and the positioning member 100, provide protection for the structural strength of the positioning member 100, and at the same time avoid the scraping caused by the positioning member 100 abutting against the side of the vehicle body.

[0124] Optionally, as shown in Figure 16, the control component 130 is a rope. A fixed pulley 150 is provided on the machine body 1 at the active end 11, and a limiting shaft 160 is provided at the driven end 12. The rope is led out from the third linkage 200, wound around the fixed pulley 150, and extends to the driven end 12. It passes through the through hole on the limiting shaft 160 and connects with the second end 1102 and the third end 1201.

[0125] By designing the control component 130 as a rope, its extension direction can be adjusted according to the structural layout of the de-icing device, significantly improving its adaptability to the device's structure. Furthermore, by installing a fixed pulley 150 at the active end 11, the extension direction of the control component 130 is smoothly redirected towards the driven end 12 after being led out from the third linkage 200. When the control component 130 moves under the influence of the third linkage 200, it experiences rolling friction with the fixed pulley 150, resulting in low friction and reduced wear on the control component 130. It also reduces the force required to move the control member 130 via the third linkage 200, making it easier for the operator to move the first linkage 110 and the second linkage 120 via the control member 130. In addition, by setting a limiting shaft 160 at the driven end 12, the extension direction of the control member 130 toward the first linkage 110 and the second linkage 120 can be adjusted by the extension direction of the limiting shaft 160, thereby adjusting the force angle applied by the control member 130 to the second end 1102 and the third end 1201, and further optimizing the driving effect of the control member 130 on the positioning member 100.

[0126] Furthermore, as shown in Figures 14 and 15, the machine body 1 is also provided with multiple threading conduits 170 located between the fixed pulley 150 and the limiting shaft 160 and spaced apart. The threading conduits 170 are hollow inside to form a threading channel 1701 for ropes to pass through. The multiple threading conduits 170 provided on the side of the machine body 1, and the threading channel 1701 formed by the cooperation of the multiple threading conduits 170, play a fixed guiding role for the extension of the control member 130 at the active end 11 and the driven end 12, so that the control member 130 can extend and retract along the extension direction of the threading channel 1701 under the drive of the third linkage member 200, thereby preventing the control member 130 from shifting.

[0127] As an optional example under this embodiment, as shown in FIG14, an elastic reset member is provided between the positioning member 100 and the body 1. The elastic reset member keeps the positioning member 100 in a vertical state. When the control member 130 applies a force, it can overcome the force of the elastic reset member and drive the positioning member 100 to switch from a vertical state to a horizontal state. When the control member 130 does not apply a force or removes the force, the force of the elastic reset member keeps the positioning member 100 in a vertical state or switches it from a horizontal state to a vertical state.

[0128] Once the body 1 is fully pushed into the bottom of the vehicle body, the operator only needs to remove the force applied to the control component 130. The positioning component 100 will then switch from a horizontal to a vertical state under the elastic action of the elastic reset component. This eliminates the need for the operator to manually switch the positioning component 100 from a horizontal to a vertical position, thus enabling the positioning component 100 to quickly engage with the side of the vehicle body. Furthermore, the elastic force of the elastic reset component can also maintain the positioning component 100 in a vertical state. During the de-icing process of the de-icing device, the operator does not need to apply additional force to maintain the position of the positioning component 100, thus optimizing the user experience of the de-icing device.

[0129] Optionally, as shown in Figure 14, the elastic reset member is a spring hinge 140. The spring hinge 140 includes a first leaf 1401, a second leaf 1402, and a spring connected between the first leaf 1401 and the second leaf 1402. The positioning member 100 is fixedly connected to the first leaf 1401, and the body 1 is fixedly connected to the second leaf 1402. The force of the spring causes the first leaf 1401 to drive the positioning member 100 to remain in the second position. The elastic reset component is set as a spring hinge 140, and is fixedly connected to the positioning component 100 and the body 1 through the first leaf 1401 and the second leaf 1402 respectively. This increases the contact area between the elastic reset component and the positioning component 100 and the body 1, so that the elastic reset component can provide more stable support for the positioning component 100. The spring applies elastic force to the first leaf 1401 and the second leaf 1402 to maintain the angle between the first leaf 1401 and the second leaf 1402, thereby maintaining the angle between the positioning component 100 and the body 1.

[0130] As another optional example under this embodiment, as shown in Figures 16 and 17, there are two of each of the first linkage 110, the second linkage 120, and the control member 130, which are symmetrically arranged at both ends of the positioning member 100 along the length direction of the vehicle body. The control mechanism also includes a synchronous shaft 180, which is connected to the end of the two control members 130 away from the rotation point. The control mechanism also includes a control rod 190 and two third linkages 200, which are arranged at both ends of the synchronous shaft 180 along the width direction of the vehicle body and are respectively connected to the control members 130 at the corresponding ends. The control rod 190 is fixed to the synchronous shaft 180.

[0131] By setting two of each of the first linkage 110, the second linkage 120, and the control element 130, and placing them at opposite ends of the positioning element 100, the rotational force applied to the positioning element 100 becomes more even, reducing the force required for a single control element 130 to rotate the positioning element 100. Furthermore, since a synchronous shaft 180 is provided, and both control elements 130 are connected to it, the operator only needs to apply force to the synchronous shaft 180. The synchronous shaft 180 rotates, simultaneously driving both control elements 130 to move, thereby respectively driving the corresponding elements on the positioning element. The first linkage 110 and the second linkage 120 on both sides of 100 eliminate the need to simultaneously drive two control components 130, reducing the difficulty of operation for the operator and optimizing the structural design of the de-icing device. Furthermore, since the end of the third linkage 200 furthest from the synchronous shaft 180 is connected to the control component 130, only a small rotation angle of the synchronous shaft 180 is needed to drive a large stroke in the end of the third linkage 200 furthest from the synchronous shaft 180, thereby achieving a larger stroke change in the control component 130 connected to the third linkage 200, and subsequently... The first linkage 110 and the second linkage 120 drive the positioning element 100 to move; that is, the positioning element 100 can be switched from a vertical state to a horizontal state by a small rotation of the synchronous shaft 180, which reduces the working space required for the control mechanism to move the positioning element 100, and helps to miniaturize the de-icing device. At the same time, the operator only needs a small force stroke to move the positioning element 100 to a horizontal state, which optimizes the structural design of the de-icing device. Furthermore, since the rotation trajectory of the synchronous shaft 180 is fixed, the third linkage 200 rotates with the synchronous shaft 180. The synchronous rotation trajectory that occurs is also fixed, which ensures that the movement trajectory of the control component 130 connected to the third linkage 200 is constant. Therefore, by rotating the synchronous shaft 180, the movement of the two control components 130 along the fixed trajectory can be realized to drive the positioning component 100 to switch from the vertical state to the horizontal state. This avoids the phenomenon of the control component 130 applying force to the first linkage 110 and the second linkage 120 due to the operator's force deviation or other factors, and provides a guarantee for the stability of the positioning component 100 in the process of switching from the vertical state to the horizontal state.
