Description

Technical Field

[0001] The present application belongs to the field of new energy vehicle technology, and specifically relates to a deicing device. Background Art

[0002] As electric vehicles enter the market, range has become a significant factor hindering their development. Drawing on the traditional car's approach of refueling to extend range, for electric vehicles, recharging depleted battery packs, or simply removing depleted packs and replacing them with fully charged ones, has become a key research and development direction for increasing electric vehicle range.

[0003] Due to limitations in battery material and charging technology, new energy vehicles (NEVs) require tens of minutes to fully charge after running out of power. For some new energy trucks with larger battery packs, this time is even longer, significantly impacting the user experience. For commercial vehicle owners in particular, waiting for charging means reduced working time. The time required to replace a battery pack is significantly shorter than the charging time required for a battery pack. Consequently, a growing number of NEVs are adopting removable battery packs for energy supply, addressing the long charging times and inconvenience of fixed battery packs. Specifically, multiple locking mechanisms are installed on the vehicle's underbody, which are locked or unlocked by mating components on the battery pack to facilitate installation and removal. Furthermore, due to the heavy weight and volume of the battery packs in these NEVs, dedicated battery replacement equipment is required for both removal and installation. However, in cold weather in northern China, especially after heavy snow or rain, the undercarriage can become covered with a thick layer of ice. This ice can also wrap around the locking mechanisms, preventing them from unlocking. Consequently, the battery packs can become frozen to the underbody, making removal difficult or even impossible. This will greatly increase the vehicle battery replacement time and cause congestion at battery replacement stations.

[0004] 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 duration of the entire battery replacement process, and the battery replacement duration is the most critical factor in determining the user's battery replacement 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 technical field. Utility Model Content

[0005] The present application provides a de-icing device to solve the technical problem that in cold weather, the ice layer on the bottom of the battery swap vehicle freezes the battery pack locking mechanism, making the battery pack difficult or even impossible to remove, resulting in difficulty in battery swapping and low battery swapping efficiency.

[0006] The technical solutions adopted in this application are:

[0007] A deicing device is used to de-ice a battery-swap vehicle. The battery pack of the battery-swap vehicle is installed on the bottom of the vehicle body through a locking mechanism to facilitate quick replacement of the battery pack. The deicing device includes a movable fuselage and a heating unit and an air outlet unit installed on the fuselage. The heating unit can supply hot air to the air outlet unit. The fuselage can move to the bottom of the vehicle body of the battery-swap vehicle and align the air outlet unit with the locking mechanism to blow the hot air to the locking mechanism.

[0008] By adopting the above technical solution, when de-icing the locking mechanism, the fuselage is moved to the bottom of the vehicle body, so that the air outlet unit is driven by the fuselage to move to a position aligned with the locking mechanism. After the air outlet unit is aligned with the locking mechanism, hot air is transported 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 achieve thermal melting of the ice layer at the locking mechanism. Since the air outlet unit and the heating unit are both installed on the fuselage, the relative position of the air outlet unit and the heating unit does not change during the movement of the fuselage. The hot air transport of the heating unit to the air outlet unit is relatively stable, so that the de-icing device can stably transport hot air to the locking mechanism through the air outlet unit, thereby quickly clearing the ice layer at the locking mechanism, allowing the battery pack to be quickly removed from the bottom of the battery swap vehicle, thereby improving the battery swap efficiency.

[0009] 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.

[0010] By adopting the above technical solution, since the air outlet unit is provided with an air storage chamber, the hot air will first be gathered in the air storage chamber during the process of the heating unit conveying hot air to the air outlet unit. After the air storage chamber is full of hot air, the heating unit continues to fill the air storage chamber with hot air, and the air pressure in the air storage chamber continues to increase. Under the action of pressure, the hot air in the air storage chamber is ejected from the air outlet. The structural form of the air outlet can be adaptively adjusted according to the structural form of the locking mechanism. For any structural form of the air outlet, 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 locking mechanism. The uniformity of ice melting reduces the possibility that some areas of the locking mechanism have melted completely while a large amount of ice still exists in other areas, thereby helping to improve the ice melting efficiency; and setting the air outlet at the top of the air storage chamber shortens the movement time of the hot air between the air outlet and the locking mechanism, thereby helping to reduce the heat energy dissipation of the hot air from the air storage to the locking mechanism, so that the hot air reaching the locking mechanism can maintain higher heat energy, which helps to improve the ice melting efficiency of the locking mechanism, and at the same time reduces the influence of airflow, air pressure or other factors caused by the hot air moving outside the air outlet unit for too long, thereby improving the de-icing efficiency of the de-icing device in many aspects.

[0011] The air storage chamber has a first air guide surface and a second air guide surface arranged at intervals, the gap between the first air guide surface and the second air guide surface forms the air outlet, and the first air guide surface and the second air guide surface extend in a direction gradually away from each other from one end close to the air outlet to the other end away from the air outlet.

[0012] By adopting the above technical solution, the hot air delivered to the air storage chamber by the heating unit moves irregularly in the air storage chamber under the action of kinetic energy, and the hot air impacts each other, causing the movement direction of the hot air to become more chaotic. By setting the first air guide surface and the second air guide surface, the hot air in the air storage chamber can be guided. Under the guidance of the first air guide surface and the second air guide surface, the hot air gradually converges in the direction close to the air outlet, and in the process of converging the hot air toward the air outlet, it is continuously adjusted its movement direction by the action of the first air guide surface and the second air guide surface, so that the hot air can move toward the locking mechanism after reaching the air outlet, reducing the probability of the hot air escaping in various directions after being ejected from the air outlet due to the deviation of the movement direction, thereby further improving the de-icing efficiency of the de-icing device; in addition, the first air guide surface and the second air guide surface extend in a direction gradually away from each other from the end close to the air outlet to the end away from the air outlet, so that the space in the air storage chamber is in the corresponding The first air guide surface and the second air guide surface are continuously tightened toward the air outlet. When the hot air in the air storage chamber moves toward the air outlet under the action of air pressure, the space of the air storage chamber is continuously contracted toward the air outlet, and the movement space left for the hot air is continuously compressed. The hot air is continuously squeezed in the gradually shrinking space. As the heating unit continues to supply air to the air storage chamber, the hot air must be discharged from the air outlet at a faster speed to ensure the balance of air pressure in the air storage chamber. Therefore, the setting of the first air guide surface and the second air guide surface 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 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 and the locking mechanism, thereby helping to reduce the heat energy dissipation of the hot air from the air storage chamber to the locking mechanism, so that the hot air arriving at the locking mechanism can maintain higher heat energy, which helps to improve the ice melting efficiency of the locking mechanism.

[0013] The first wind guide surface and the second wind guide surface are symmetrically arranged along the air outlet and are both inclined, extending gradually away from each other from top to bottom; or, the first wind guide surface extends in a horizontal direction, and the second wind guide surface extends obliquely from one end close to the air outlet to the end away from the air outlet in a direction gradually away from the first wind guide surface.

[0014] By adopting the above technical solution, the first air guide surface and the second air guide surface are arranged symmetrically, so that the hot air guided by the first air guide surface and the second air guide surface respectively to the air outlet has a relatively symmetrical movement path, converges at the air outlet and is ejected together to the locking mechanism; and the first air guide surface is set to extend in the horizontal direction, and the second air guide surface extends obliquely from the end close to the air outlet to the end away from the air outlet in a direction gradually away from the first air guide surface, so that when the hot air moves in the air storage chamber, it moves in the horizontal direction under the guidance of the first guide surface, and is continuously converged and squeezed under the action of the second air guide surface to move rapidly.

[0015] The first wind guide surface and the second wind guide surface are adjacent to each other on one side and have a first wind guide plate and a second wind guide plate extending upward, respectively. The first wind guide plate and the second wind guide plate are arranged in parallel or extend from top to bottom in a direction gradually away from each other to form the air outlet.

[0016] By adopting the above technical solution, the arrangement of the first air guide plate and the second air guide plate plays a further guiding role for the hot air, so that the hot air ejected from the air storage chamber moves upward under the guidance of the first air guide plate and the second air guide plate. After the hot air leaves the air outlet, it can still move upward in the vertical direction under the action of inertia, thereby reducing the probability of the hot air escaping to the surroundings after leaving the air outlet, and ensuring the retention amount of the hot air reaching the locking mechanism; in addition, the arrangement of the first air guide plate and the second air guide plate also plays a role in blocking the external environment for the hot air, so that the hot air is not affected by the external air pressure and airflow during the movement of the air outlet, thereby further This provides a guarantee for the hot air to smoothly reach the locking mechanism to melt the ice; furthermore, the first air guide plate and the second air guide plate are set to be set upward and parallel, so that the movement direction of the hot air in the air outlet is vertically upward, so that the hot air still has the inertia to move toward the locking mechanism in the vertical direction after being ejected from the air outlet, and the first air guide plate and the second air guide plate are set to gradually move away from each other from top to bottom, so that the hot air is further converged and compressed during the movement of the air outlet, so that the hot air ejected from the air outlet has a faster speed to quickly reach the locking mechanism, thereby reducing the loss of heat energy during the movement of the hot air from the air outlet to the locking mechanism.

[0017] There are two rows of locking mechanisms, which are arranged on both sides of the battery pack along the length direction of the battery pack, and there are two corresponding air outlet units. The two air outlet units correspond to two rows of locking mechanisms, which are respectively extended along the width direction of the fuselage, and the air outlet extends from one end of the air outlet unit to the other end along the width direction of the fuselage; or, there are multiple locking mechanisms, which are arranged on the battery pack at preset positions, and there are multiple air outlets, and the multiple air outlets correspond to the positions of each locking mechanism; and / or, two air expansion plates are provided on the top of the air outlet, and the two air expansion plates are correspondingly arranged on both sides of the air outlet, extending from bottom to top in a direction gradually away from each other.

[0018] By adopting the above technical solution, two rows of locking mechanisms are set up, which makes the connection between the battery pack and the battery-swap vehicle more stable and reliable. Two air outlet units are set up, and the two rows of locking mechanisms are de-iced simultaneously by the two air outlet units, thereby realizing the synchronous de-icing of the locking mechanisms on both sides of the battery pack by the de-icing device, shortening the de-icing time of the battery-swap vehicle, and greatly improving the de-icing efficiency of the de-icing device; in addition, since the two air outlet units correspond one to one with the two rows of locking mechanisms, when the fuselage is moved 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, and the other air outlet unit will also be aligned with the locking mechanism accordingly, eliminating the need to align the two air outlet units. The air outlet unit is aligned with the two rows of locking mechanisms respectively, thereby reducing the preparation time required before the de-icing operation and further improving the de-icing efficiency of the de-icing device; furthermore, the air outlet is set to extend along the length direction of the battery pack, so that the hot air ejected from the air storage chamber can evenly supply air to the locking mechanisms located on the side of the length direction of the battery pack, thereby improving the uniformity of the air supply of the de-icing device to each locking mechanism, thereby ensuring that the ice layer at each locking mechanism is evenly heated and the melting time is roughly the same; and setting a plurality of air outlets and aligning them with each locking mechanism makes the air outlet unit have higher de-icing accuracy for the locking mechanism, and each air outlet is aimed at the corresponding locking mechanism. The mechanism supplies air, which improves the utilization efficiency of hot air while ensuring uniform air supply, and increases the de-icing efficiency of the de-icing device; due to the provision of the air diffuser, after the hot air is ejected from the air outlet, part of the hot air continues to move upward in the vertical direction, and part of the hot air has a tendency to move obliquely due to the change in air pressure. This part of the hot air with a tendency to move obliquely moves along the extension direction of the air diffuser under the guidance of the air diffuser, which increases the working efficiency of the hot air and also helps to reduce the requirements for the design of the air outlet size, that is, when the diameter of the air outlet is small, the hot air can still achieve all-round coverage of the ice layer at the locking mechanism under the action of the air diffuser; when the air outlet is After the ice layer is melted, the melted water droplets will drip downwards under the action of their own gravity, and the hot air at the air outlet has higher thermal energy, so it can instantly evaporate the water droplets into water vapor, and the air diffuser can collect the ice melt water on the side of the air outlet, so that the water droplets dripping on the air diffuser move along the air diffuser toward the air outlet under the action of their own gravity and quickly evaporate into water vapor under the action of the hot air, reducing the probability of ice melt water dripping onto the air outlet unit or other components to interfere with the components of the de-icing device; therefore, by setting the air diffuser, the ice layer removed by the de-icing device is released more in the form of water vapor, reducing the pressure on the collection and processing of ice melt water.

[0019] The air storage chamber also 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 second air guide surface is connected to the third air guide surface at one end away from the air outlet, the fourth air guide surface is connected between the third air guide surface and the second air guide surface, the third air guide surface is extended upward at an angle from the second air guide surface, and a receiving groove is formed between the second air guide plate, the second air guide surface and the third air guide surface to accommodate the ice water that falls after the air outlet unit delivers hot air to the locking mechanism, and the receiving groove has guide holes connected to the outside of the fuselage at both ends along the width direction of the fuselage.

[0020] By adopting the above technical solution, the third air guide surface and the fourth air guide surface can, on the one hand, guide the hot air entering the air storage chamber, so that the hot air moves more smoothly toward the air outlet under the guidance of the third air guide surface and the fourth air guide surface, thereby reducing the kinetic energy loss caused by the mutual impact of the hot air due to uneven movement direction; in addition, the water droplets and small ice cubes after the ice layer melts will fall downward, 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 the water droplets and ice cubes that fall to the side of the air outlet. The bottom of the receiving groove is a high-temperature air storage chamber, which continuously supplies temperature to the receiving groove to quickly melt the ice cubes that fall into the receiving groove, and discharges the melted ice water to the outside of the fuselage through the guide hole, thereby reducing the pressure on collecting and cleaning the ice water, and reducing the risk of the melted ice water affecting the other components of the de-icing device.

[0021] The de-icing device also includes a first transmission pipe connecting the heating unit with the air storage chamber, the first transmission pipe including a first pipe body and a first hot air transition piece connecting the first pipe body with the air storage chamber, the first hot air transition piece having a first hot air input port connected to the first pipe body and a first hot air output port connected to the bottom of the air storage chamber, the first hot air output port opening facing upward to be connected to the bottom surface of the air storage chamber; preferably, the first hot air input port and the first hot air output port are located on both sides of the first hot air transition piece, the first hot air transition piece is provided with two oppositely arranged first air gathering plates near the first hot air input port, the two first air gathering plates gradually approach each other from one end of the hot air input port to one end of the first hot air output port; and / or the first hot air transition piece is provided with an air induction plate near the first hot air output port, the air induction plate being inclined so that the cross-section of the first hot air transition piece gradually increases from the end away from the first hot air output port to the end close to the first hot air output port.

[0022] By adopting the above technical solution, when the heating unit transports hot air to the air storage chamber through the first transmission pipe, the hot air in the first tube body will be transported to the air storage chamber through the first hot air transition piece, and the first hot air transition piece plays the function of connecting the first tube body and the air storage chamber, thereby improving the tightness of the connection between the first transmission pipe and the air storage chamber, and 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 transmission rate of the heating unit to the air outlet unit; in addition, the first hot air output port is connected with the bottom surface of the air storage chamber, so that the hot air entering the air storage chamber from the first hot air transition piece can gradually accumulate at the bottom of the air storage chamber and be ejected from the air outlet after filling the air storage chamber from bottom to top, which helps to improve the storage stability of the hot air in the air storage chamber; furthermore, a first air collecting plate is set at the first hot air transition piece near the first hot air input port, which can collect the hot air from the first hot air input port The hot air entering the first hot air transition piece has a converging effect, and the movement space of the hot air is gradually reduced under the action of the first air collecting plate, and the hot air moves quickly to the first hot air output port under the push of the subsequent hot air pressure. That is, the provision of the first air collecting plate speeds up the movement speed of the hot air in the first hot air transition piece, which helps to improve the hot air transmission efficiency; and since the first hot air output port is located at the bottom of the air storage chamber, the hot air needs to undergo a change in movement direction during the movement from the first hot air input port to the first hot air output port. Therefore, by providing an air guide plate at the first hot air output port, the cross-sectional area of ​​the first hot air transition piece is increased, a larger movement space is provided for the hot air, and the impact of the hot air on the inner wall of the first hot air transition piece during the turning process is reduced. At the same time, the hot air in the first hot air transition piece is guided and turned, thereby improving the smoothness of the hot air discharged from the first hot air output port in multiple directions.

[0023] The de-icing device also includes an air storage box located between the two air outlet units and a second transmission pipe connecting the heating unit with the air storage box. The air storage box receives hot air from the heating unit through the second transmission pipe, and transports 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 from the air outlet to the locking mechanism. The first air supply channel and the second air supply channel are symmetrically arranged along the width direction of the fuselage.

[0024] By adopting the above technical solution, when the heating unit supplies air to the air outlet unit, the hot air will first be transported 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 transport hot air to the air storage box. Under the action of pressure, the hot air in the air storage box is respectively supplied to the two air outlet units through the symmetrically arranged first air supply channel and the second air supply channel. In this way, the temperature and speed of the hot air output to the locking mechanism by the two air outlet units are roughly equal, thereby ensuring that the deicing rate of the locking mechanism by the two air outlet units is roughly the same, so that the locking mechanism can be de-iced synchronously, reducing the probability of one locking mechanism having completed de-icing while the other locking mechanism needs to continue de-icing due to factors such as the air supply size and temperature difference of the air outlet unit, thereby minimizing the dry blowing of hot air to the locking mechanism that has completed de-icing.

[0025] The second transmission pipe includes a second pipe body and a second hot air transition piece connecting the second pipe body with the air storage chamber, the second hot air transition piece is arranged under the air outlet unit close to the side of the heating unit and has a second hot air input port connected to the second pipe body and a second hot air output port connected to the air storage box; preferably, the second hot air input port and the second hot air output port are located on both sides of the second hot air transition piece, and the second hot air transition piece is provided with two oppositely arranged second air gathering plates near the second hot air input port, and the two second air gathering plates gradually approach each other from one end of the second hot air input port to one end of the second hot air output port.

[0026] By adopting the above technical solution, when the heating unit transmits hot air to the air storage box through the second transmission pipe, the hot air in the second pipe body will be transmitted to the air storage box through the second hot air transition piece. The second hot air transition piece plays the function of connecting the second pipe body and the air storage box, thereby improving the tightness of the connection between the second transmission pipe and the air storage box, and effectively reducing the probability of hot air escaping during the transmission process from the heating unit to the air storage box, thereby improving the hot air transmission rate of the heating unit to the air storage box; in addition, arranging the second hot air transition piece to pass through below the air outlet unit can avoid the second hot air transition piece from affecting the air supply from the air outlet unit to the locking mechanism. The second hot air input port and the second hot air output port are respectively located on both sides of the second hot air transition piece and a second wind gathering plate is arranged near the second hot air output port, which can gather the hot air entering the second hot air transition piece from the second hot air input port. Under the action of the second wind gathering plate, the movement space of the hot air is gradually reduced, and it moves rapidly to the second hot air output port under the push of the subsequent hot air pressure. That is, the arrangement of the second wind gathering plate accelerates the movement speed of the hot air in the second hot air transition piece, 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.

[0027] There is one air storage box, and along the length direction of the fuselage, the two ends of the air storage box are respectively abutted against the two air outlet units, and the first air supply channel and the second air supply channel are provided on both sides of the air storage box; or, there are two air storage boxes, the two air storage boxes are spaced apart along the width direction of the fuselage, and the two ends of the air storage box along the length direction of the fuselage are respectively abutted against the two air outlet units, and each air storage box is provided with the first air supply channel and the second air supply channel on the side facing the other air storage box.

[0028] By adopting the above technical solution, the air storage box is set as one, which reduces the difficulty of installing the air storage box between the two air outlet units, and the two air outlet units can also play a role in coordinating and fixing the air storage box. The first air supply channel and the second air supply channel are provided on both sides of the air storage box, which increases the efficiency of hot air transmission from the air storage box to the two air outlet units and reduces the mutual interference between the first air supply channel and the second air supply channel; and when two air storage boxes are set, the two air outlet units can simultaneously play a role in positioning the two air storage boxes, and integrate the first air supply channel and the second air supply channel between the two air outlet boxes, which is convenient for the unified assembly of the first air supply channel and the second air supply channel.

[0029] An upper heat insulation plate and a lower heat insulation plate are respectively provided on the upper surface and the lower surface of the fuselage, wherein the upper heat insulation plate includes a plurality of heat insulation sub-plates, and a preset gap is provided between two adjacent heat insulation sub-plates to avoid the air outlet. In the length direction of the fuselage, the width of the preset gap is greater than the width of the air outlet so that ice water falling after the air outlet blows hot air to the locking mechanism is discharged from the gap between the air outlet and the heat insulation sub-plates.

[0030] By adopting the above technical solution, the upper insulation board can block the heat dissipated upward by the air from the air outlet unit and the air storage box, slowing down the heat loss from the air outlet unit and the air storage box, reducing the thermal interference of the air outlet unit and the air storage box on the battery pack, and helping to maintain the thermal energy content of the hot air ejected from the air outlet, thereby helping to improve the de-icing efficiency of the de-icing device; in addition, the upper insulation board can also carry the melted ice and ice cubes falling from above, preventing the ice water from falling onto the air outlet unit and the air storage box or other components of the de-icing device, and preventing the dripping ice water from causing heat energy loss to the air outlet unit. At the same time, after the de-icing work is completed, the ice water falling on the upper insulation board can also be easily collected and processed; in addition, the preset gap between the two adjacent insulation sub-boards also provides space for the ice water to slide down, making the ice water. The lower insulation component can block the heat dissipated downward by the air from the air outlet unit and the air storage box, slowing down the heat loss from the air outlet unit and the air storage box.

[0031] The heating unit has a smoke exhaust pipe for discharging waste gas. The smoke exhaust pipe is led out from the heating unit and communicated with the air storage chamber. A filter is provided in the smoke exhaust pipe to filter the waste gas.

[0032] By adopting the above technical solution, the setting of the smoke exhaust pipe plays a role in guiding the exhaust of the smoke generated when the heating unit produces hot air, preventing the smoke from escaping and affecting the de-icing operators; in addition, since the temperature of the smoke generated by the heating unit when producing hot air is relatively high, or even higher than the hot air temperature, the smoke exhaust pipe is arranged to be connected to the air storage chamber, and the smoke moves toward the locking mechanism under the influence of the hot air in the air storage chamber and plays a role in assisting ice melting, thereby realizing the recycling of high-temperature smoke and increasing the de-icing efficiency of the de-icing device; and the filter in the smoke exhaust pipe can filter and intercept solid particles, smoke oil, etc. in the smoke, preventing these solid debris from contaminating the locking mechanism or the battery pack.

[0033] Along the length direction of the fuselage, the fuselage has an active end and a driven end relatively arranged. The active end is exerted with 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 load-bearing portion, and the driven end is provided with a positioning member. When the fuselage enters the bottom of the vehicle body, the positioning member can be in a horizontal state to avoid the body of the battery-swap vehicle. When the fuselage completely enters the bottom of the vehicle body and is in place, the positioning member can switch to a vertical state and abut against one side of the vehicle body, and the load-bearing portion abuts against the other side of the vehicle body so that the air outlet corresponds to the locking mechanism.

[0034] By adopting the above technical solution, the positioning part can cooperate with the side of the vehicle body after the fuselage is completely entered into the bottom of the vehicle body. When the positioning part is cooperated with the vehicle body, the air outlet unit reaches the relative position with the locking mechanism, thereby realizing the precise air supply of the air outlet unit to the locking mechanism. Therefore, the operator can obtain the alignment of the air outlet unit by observing the coordination state of the positioning part and the vehicle body, thereby 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, which greatly reduces the difficulty of the operator in adjusting the position of the de-icing device during the de-icing operation. On the one hand, it shortens the preparation time required for position calibration of the air outlet unit before de-icing, thereby improving the de-icing efficiency. On the other hand, when the positioning part is cooperated with the side of the vehicle body, the air outlet unit is in the de-icing position opposite to the locking mechanism, thereby avoiding the air outlet unit and the locking mechanism caused by manual alignment. The locking mechanism may have position deviation, which further improves the de-icing efficiency of the de-icing device; in addition, the active end and the driven end are respectively arranged on the front and rear sides of the fuselage, and the bearing part and the positioning part are respectively arranged at the active end and the driven end. On the one hand, it provides a force position for the operator to drive the fuselage. The operator applies the driving force to the bearing part to realize the movement of the fuselage, which reduces the difficulty of moving the fuselage; in addition, the positioning part and the bearing part are respectively against the two sides of the body of the battery swap vehicle, so that the positioning part and the bearing part can respectively stop the airflow from the side of the body to the bottom of the body, reduce the impact of the airflow on the hot air ejected 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 to reduce the diffusion of heat from the bottom of the body to the side of the body, which helps to further improve the de-icing speed of the de-icing device.

[0035] The de-icing device also includes a control mechanism connected to the positioning member, the control mechanism includes a first link, a second link and a control member, the first end of the first link is rotatably connected to the positioning member, the second end of the first link is rotatably connected to the third end of the second link, and the fourth end of the second link is rotatably connected to the fuselage, 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, so that the first link and the second link are rotated, thereby realizing that the positioning member can be switched between a horizontal state and a vertical state.

[0036] By adopting the above technical solution, the control member can simultaneously act on the second end of the first link and the third end of the second link, and drive the first link and the second link to rotate synchronously, thereby realizing the switching of the positioning member between the horizontal state and the vertical state, so as to realize the positioning member avoiding the vehicle body or cooperating with the side of the vehicle body; in this process, the first link and the positioning member, the second link and the positioning member, and the first link and the second link are all rotationally connected, thereby reducing the friction resistance that the control member needs to overcome in the process of driving the first link and the second link to move, thereby making the switching of the positioning member between the horizontal state and the vertical state smoother; in addition, since the first link and the second link rotate synchronously and approach each other under the drive of the control member, the rotation speed of the positioning member, that is, the switching speed from the horizontal state to the vertical state, is accelerated, thereby reducing the working stroke of the control member when driving the positioning member to switch positions, which helps to optimize the structural design of the control mechanism.

[0037] An elastic return member is provided between the positioning member and the fuselage, and the elastic return member keeps the positioning member in a vertical state. When the control member applies a force, it can overcome the force of the elastic return member and drive the positioning member to switch from a vertical state to a horizontal state; when the control member does not apply a force or removes the force, the force of the elastic return member keeps the positioning member in a vertical state or switches from a horizontal state to a vertical state.

[0038] By adopting the above technical solution, when the fuselage is completely pushed into the bottom of the vehicle body, the operator only needs to cancel the force applied to the control part, and the positioning part will switch from the horizontal state to the vertical state under the elastic action of the elastic return part, eliminating the operator's need to switch the position of the positioning part from the horizontal state to the vertical state, thereby achieving rapid coordination between the positioning part and the side of the vehicle body; in addition, the elastic force of the elastic return part can also maintain the positioning part in the vertical state. During the de-icing process of the de-icing device, the operator does not need to apply additional force to maintain the state of the positioning part, thereby optimizing the user experience of the de-icing device.

[0039] The first linking member, the second linking member and the control member are each provided with two, which are symmetrically arranged at the two ends of the positioning member along the length direction of the vehicle body. The control mechanism also includes a synchronization shaft, which is connected to the end of the two control members away from the rotation point; the control mechanism also includes a control rod and two third linking members, and the two third linking members are arranged at the two ends of the synchronization shaft along the width direction of the vehicle body and are respectively connected to the control members at the corresponding ends, and the control rod is fixed to the synchronization shaft.

[0040] By adopting the above technical solution, the number of the first link, the second link and the control member is set to two, and they are respectively arranged at both ends of the positioning member, so that the rotational force applied to the positioning member is more uniform, and the force pressure of the single control member to drive the positioning member to rotate is reduced; in addition, since a synchronous shaft is provided and the two control members are connected to the synchronous shaft, the operator only needs to apply a force to the synchronous shaft, and the synchronous shaft drives the two control members to move at the same time by rotating to respectively drive the first link and the second link located on both sides of the positioning member, eliminating the operation of driving the two control members to work at the same time, reducing the difficulty of the operator's work and optimizing the structural design of the de-icing device; furthermore, since the end of the third link away from the synchronous shaft is connected to the control member, only a small rotation angle of the synchronous shaft is required to drive the third link to move away from one end of the synchronous shaft to have a larger stroke, thereby realizing a larger stroke change of the control member connected to the third link, and then through the first link The first link member and the second link member drive the positioning member to move; that is, the positioning member can be driven to switch from the vertical state to the horizontal state by a small rotation of the synchronous shaft, which reduces the working space required for the control mechanism to drive the positioning member to move, contributes to the miniaturization of the de-icing device, and at the same time, the operator only needs a small force stroke to drive the positioning member to move to the horizontal state, thereby optimizing 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 link member as the synchronous shaft rotates is also fixed, thereby ensuring that the movement trajectory of the control member connected to the third link member is constant. Therefore, by rotating the synchronous shaft, the two control members can be moved along the fixed trajectory to drive the positioning member to switch from the vertical state to the horizontal state, thereby avoiding the occurrence of the force deviation of the control member on the first link member and the second link member due to the force deviation of the operator or other factors, thereby providing a guarantee for the stability of the positioning member in the process of switching from the vertical state to the horizontal state.

[0041] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0042] When de-icing the locking mechanism, the fuselage is moved to the bottom of the vehicle body, so that the air outlet unit is driven by the fuselage to move to a position aligned with the locking mechanism. After the air outlet unit is aligned with the locking mechanism, hot air is transported 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 at the locking mechanism. Since the air outlet unit and the heating unit are both installed on the fuselage, the relative positions of the air outlet unit and the heating unit do not change during the movement of the fuselage. The hot air transport from the heating unit to the air outlet unit is relatively stable, allowing the de-icing device to stably transport hot air to the locking mechanism through the air outlet unit, thereby quickly clearing the ice layer at the locking mechanism and allowing the battery pack to be quickly removed from the bottom of the battery swap vehicle, thereby improving the battery swap efficiency.

[0093] like Figure 1 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 13 、 Figures 19 to 21 As shown, a deicing device is used to de-ice a battery-swap vehicle. The battery pack of the battery-swap vehicle is installed on the bottom of the vehicle body through a locking mechanism 210 to facilitate quick replacement of the battery pack. The deicing device includes a movable fuselage 1 and a heating unit 2 and an air outlet unit 3 installed on the fuselage 1. The heating unit 2 can supply hot air to the air outlet unit 3. The fuselage 1 can move to the bottom of the vehicle body of the battery-swap vehicle and align the air outlet unit 3 with the locking mechanism 210 to blow hot air to the locking mechanism 210.

[0094] Figure 20The middle arrow Y indicates the length direction of the battery-swap vehicle 220, and the arrow X indicates the movement direction of the de-icing device into the bottom of the battery-swap vehicle 220. The fuselage 1 enters the bottom of the battery-swap vehicle 220 along the side of the body. When de-icing the locking mechanism 210, the fuselage 1 is moved to the bottom of the body, so that the air outlet unit 3 moves to a position aligned with the locking mechanism 210 under the drive of the fuselage 1. After the air outlet unit 3 is aligned with the locking mechanism 210, hot air is transported to the air outlet unit 3 through the heating unit 2. The hot air is ejected 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 the air outlet unit 3 and the heating unit 2 are both installed on the fuselage 1, the relative positions of the air outlet unit 3 and the heating unit 2 will not change during the movement of the fuselage 1. The hot air delivery of the heating unit 2 to the air outlet unit 3 is relatively stable, so that the de-icing device can stably deliver hot air to the locking mechanism 210 through the air outlet unit 3, thereby quickly clearing the ice layer at the locking mechanism 210, allowing the battery pack to be quickly removed from the bottom of the battery-swapping vehicle, thereby improving the battery-swapping efficiency.

[0095] Preferably, a moving wheel 15 is provided at the bottom of the fuselage 1 , and a handrail 14 is provided on the side of the fuselage 1 facing away from the vehicle body, so that an operator can push and pull the fuselage 1 in and out of the bottom of the vehicle body through the handrail 14 .

[0096] As a preferred embodiment of the present application, Figures 2 to 4 As shown, the air outlet unit 3 includes an air storage chamber 31 and an air outlet 32. The air outlet unit 3 has a hollow interior to form the air storage chamber 31. The bottom or side of the air storage chamber 31 is connected to the heating unit 2, and the air outlet 32 ​​is located at the top of the air storage chamber 31.

[0097] Since the air outlet unit 3 is provided with an air storage chamber 31, the hot air will first be gathered in the air storage chamber 31 during the process of the heating unit 2 conveying hot air to the air outlet unit 3. After the air storage chamber 31 is full of hot air, the heating unit 2 continues to fill the air storage chamber 31 with hot air, and the air pressure in the air storage chamber 31 is continuously increased. Under the action of the pressure, the hot air in the air storage chamber 31 is ejected from the air outlet 32. The structural form of the air outlet 32 ​​can be adaptively adjusted according to the structural form of the locking mechanism. For any structural form of the air outlet 32, the hot air in the air storage chamber 31 can be uniformly ejected from the air outlet 32 ​​under the action of the air pressure, which helps to improve the The locking mechanism melts ice uniformly, reducing the possibility that some areas of the locking mechanism have melted completely while other areas still have a large amount of ice, thereby helping to improve the ice melting efficiency; and setting the air outlet 32 ​​at the top of the air storage chamber 31 shortens the movement time of the hot air between the air outlet 32 ​​and the locking mechanism, thereby helping to reduce the heat energy dissipation of the hot air from the air storage to the locking mechanism, so that the hot air reaching the locking mechanism can maintain higher heat energy, which helps to improve the ice melting efficiency of the locking mechanism, and at the same time reduces the influence of airflow, air pressure or other factors on the hot air due to the long movement time outside the air outlet unit 3, thereby improving the de-icing efficiency of the de-icing device in many aspects.

[0098] As a preferred embodiment of this embodiment, Figures 2 to 5 As shown, the air storage chamber 31 has a first air guide surface 33 and a second air guide surface 34 arranged at intervals, and 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 in a direction gradually away from each other from one end close to the air outlet 32 ​​to the other end away from the air outlet 32.

[0099] Since the hot air delivered to the air storage chamber 31 by the heating unit 2 moves irregularly in the air storage chamber 31 under the action of kinetic energy, and the hot air impacts each other, resulting in a more chaotic movement direction of the hot air, the first air guide surface 33 and the second air guide surface 34 are provided to guide the hot air in the air storage chamber 31. Under the guidance of the first air guide surface 33 and the second air guide surface 34, the hot air gradually converges in the direction close to the air outlet 32, and is guided by the first air guide surface 33 and the second air guide surface 34 in the process of converging the hot air toward the air outlet 32. The second air guide surface 34 continuously adjusts its movement direction, so that the hot air can move toward the locking mechanism after reaching the air outlet 32, reducing the probability of the hot air escaping in various directions after being ejected from the air outlet 32 ​​due to deviation in the movement direction, thereby further improving the de-icing efficiency of the de-icing device; in addition, the first air guide surface 33 and the second air guide surface 34 extend in a direction gradually moving away from each other from the end close to the air outlet 32 ​​to the end away from the air outlet 32, so that the space in the air storage chamber 31 is The air guide surface 33 and the second air guide surface 34 are continuously tightened toward the air outlet 32. When the hot air in the air storage chamber 31 moves toward the air outlet 32 ​​under the action of air pressure, the space of the air storage chamber 31 is continuously contracted toward the air outlet 32, so the space left for the hot air to move is continuously compressed. The hot air is continuously squeezed in the gradually shrinking space. As the heating unit 2 continues to supply air to the air storage chamber 31, the hot air must be discharged from the air outlet 32 ​​at a faster speed to ensure that the air pressure in the air storage chamber 31 is constant. Balance; therefore, the setting 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 quickly move 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 energy dissipation of the hot air from the air storage port to the locking mechanism, so that the hot air reaching the locking mechanism can maintain higher heat energy, which helps to improve the ice melting efficiency of the locking mechanism.

[0100] This embodiment does not limit the structural form of the first wind guide surface 33 and the second wind guide surface 34, which can be as follows: Figures 2 to 5 The plane shown in FIG. 1 may also be a curved surface that is concave inward or convex outward toward the air storage chamber 31 in another embodiment.

[0101] This embodiment does not limit the positional relationship between the first air guide surface 33 and the second air guide surface 34, and may adopt any of the following examples:

[0102] Example 1: Figure 3As shown, 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 away from each other from top to bottom. The first air guide surface 33 and the second air guide surface 34 are symmetrically arranged so 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 symmetrical movement path, converges at the air outlet 32 ​​and is ejected together to the locking mechanism.

[0103] Example 2: For example Figure 4 As shown, the first air-guiding surface 33 extends horizontally, and the second air-guiding surface 34 extends obliquely from the end closest to the air outlet 32 ​​to the end further away from the air outlet 32, gradually moving away from the first air-guiding surface 33. The first air-guiding surface 33 is configured to extend horizontally, and the second air-guiding surface 34 extends obliquely from the end closest to the air outlet 32 ​​to the end further away from the air outlet 32, gradually moving away from the first air-guiding surface 33. This allows the hot air to move horizontally in the air storage chamber 31 under the guidance of the first guide surface, and to be continuously converged and squeezed by the second guide surface 34, resulting in rapid movement.

[0104] Preferably, if Figure 3 、 Figure 4 As shown, the adjacent sides of the first wind guide surface 33 and the second wind guide surface 34 respectively have a first wind guide plate 35 and a second wind guide plate 36 extending upward, and the first wind guide plate 35 and the second wind guide plate 36 are arranged in parallel or extend from top to bottom gradually away from each other to form an air outlet 32.

[0105] The arrangement of the first air guide plate 35 and the second air guide plate 36 further guides the hot air, so that the hot air ejected from the air storage chamber 31 moves 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 upward in the vertical direction 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 the amount of hot air reaching the locking mechanism; in addition, the arrangement of the first air guide plate 35 and the second air guide plate 36 also plays a role in blocking the external environment for the hot air, so that the hot air is not affected by the external air pressure and airflow during the movement of the air outlet 32, thereby further ensuring the smooth flow of the hot air. The hot air is then directed upwards to the locking mechanism for ice melting, thereby ensuring that the hot air reaches the locking mechanism for ice melting. Furthermore, the first air guide plate 35 and the second air guide plate 36 are arranged to be arranged in parallel and upwards, so that the hot air moves vertically upwards in the air outlet 32, so that the hot air still has the inertia to move vertically toward 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 arranged to move away from each other gradually from top to bottom, so that the hot air is further converged and compressed during the movement of the air outlet 32, thereby making the hot air ejected from the air outlet 32 ​​have a faster speed to quickly reach the locking mechanism, thereby reducing the loss of heat energy during the movement of the hot air from the air outlet 32 ​​to the locking mechanism.

[0106] This embodiment does not limit the structural form of the locking mechanism and the air outlet 32, which can adopt any of the following embodiments:

[0107] Example 1: Figure 1 、 Figure 2 、 Figure 21 As shown, there are two rows of locking mechanisms 210, which are arranged on both sides of the battery pack along the length direction of the battery pack. Two air outlet units 3 are correspondingly provided. The two rows of locking mechanisms 210 corresponding to the two air outlet units 3 are respectively extended along the width direction of the fuselage 1, and the air outlet 32 ​​extends from one end of the air outlet unit 3 to the other end along the width direction of the fuselage 1.

[0108] The air outlet 32 ​​extends from one end of the air outlet unit 3 to the other along the length of the battery pack. This arrangement allows the hot air ejected from the air storage chamber 31 to evenly supply the locking mechanisms 210 located on the sides of the battery pack along the length of the battery pack. This improves the uniformity of the de-icing device's air supply to each locking mechanism 210, ensuring that the ice layer at each locking mechanism 210 is evenly heated and melts for approximately the same amount of time.

[0109] The air outlet 32 ​​in this embodiment is suitable for when the locking mechanisms 210 on the side of the battery pack are densely distributed or the locking mechanisms 210 are in the form of strips extending along the length of the battery pack. The distance between the locking mechanisms 210 along the length of the battery pack is short. The air outlet 32 ​​extending along the length of the battery pack uniformly supplies air to multiple densely arranged locking mechanisms 210, which helps to simplify the structural design of the air outlet 32 ​​and reduce the difficulty of manufacturing the air outlet 32.

[0110] Example 2: Multiple locking mechanisms are provided, positioned at predetermined locations on the battery pack, and multiple air outlets are provided, each corresponding to the position of each locking mechanism. The arrangement of the locking mechanisms in this configuration is diverse and can be configured according to actual needs. For example, Chinese Publication No. CN106080159A discloses one arrangement of locking mechanisms. If the locking mechanism becomes frozen by ice or snow in winter, the deicing device of this embodiment can be used to blow hot air through the locking mechanism to remove the ice and snow.

[0111] The air outlet in this embodiment is suitable for when the locking mechanisms on the side of the battery pack are sparsely distributed, that is, the distance between the locking mechanisms is long. By setting one-to-one corresponding air outlets to supply air to each locking mechanism for de-icing, the heat energy loss caused by ineffective air supply to the place where the locking mechanism is not set is reduced.

[0112] Example three: Figures 2 to 4As shown, two air diffusion plates 37 are provided on the top of the air outlet 32. The two air diffusion plates 37 are correspondingly provided on both sides of the air outlet 32 ​​and extend gradually away from each other from bottom to top.

[0113] Due to the provision of the air diffuser 37, after the hot air is ejected from the air outlet 32, part of the hot air continues to move upward in the vertical direction, and part of the hot air has a tendency to move obliquely due to the change in air pressure. This part of the hot air with a tendency to move obliquely moves along the extension direction of the air diffuser 37 under the guidance of the air diffuser 37, which increases the working efficiency of the hot air and helps to reduce the requirements for the size design of the air outlet 32. That is, when the diameter of the air 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 air diffuser 37; in addition, when the ice layer above the air outlet 32 ​​is melted, the melted water droplets will be on the ice layer. The water droplets drip downward under the action of gravity, and the hot air at the air outlet 32 ​​has higher thermal energy, so it can instantly evaporate the water droplets into water vapor, and the air diffuser 37 can collect the ice melt water on the side of the air outlet 32, so that the water droplets dripping on the air diffuser 37 move along the air diffuser 37 toward the air outlet 32 ​​under the action of their own gravity and quickly evaporate into water vapor under the action of the hot air, reducing the probability of ice melt water dripping onto the air outlet unit 3 or other components to interfere with the components of the de-icing device; therefore, by setting the air diffuser 37, the ice layer removed by the de-icing device is released more in the form of water vapor, reducing the pressure on the collection and processing of the ice melt water.

[0114] Based on the above example 2, preferably, Figures 4 to 6 As shown, the air storage chamber 31 also 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 at an angle. 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 accommodate the ice water that falls after the air outlet unit 3 delivers hot air to the locking mechanism, and the receiving groove 4 has a guide hole 41 connected to the outside of the fuselage 1 at both ends along the width direction of the fuselage 1. The fourth air guide surface 39 can be tilted 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 as follows Figure 7 As shown in FIG, it is L-shaped, with the lower end connected to the second wind guide surface 34 and the upper end connected to the third wind guide surface 38.

[0115] On the one hand, the third air guide surface 38 and the fourth air guide surface 39 can guide the hot air entering the air storage chamber 31, so that the hot air moves more smoothly toward the air outlet 32 ​​under the guidance of the third air guide surface 38 and the fourth air guide surface 39, 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 layer melts will fall downward, and 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 the water droplets and ice cubes that fall to the side of the air outlet 32. The bottom of the receiving groove 4 is a high-temperature air storage chamber 31, and the air storage chamber 31 continuously supplies heat to the receiving groove 4 to quickly melt the ice cubes that fall into the receiving groove 4, and discharges the melted ice water to the outside of the fuselage 1 through the guide hole 41, thereby reducing the pressure on collecting and cleaning the ice water and reducing the risk of the melted ice water affecting other components of the de-icing device.

[0116] Specifically, two vertical plates 18 are respectively provided at both ends along the extending direction of the accommodating groove 4 , the second air guide plate 36 , the second air guide surface 34 and the third air guide surface 38 are all in contact with the vertical plates 18 , and the vertical plates 18 are provided with guide holes 41 .

[0117] As a preferred embodiment of the present application, Figure 5 、 Figure 7 、 Figure 8 As shown, the de-icing device also includes a first transmission pipe 6 connecting the heating unit 2 with the air storage chamber 31. The first transmission pipe 6 includes a first tube body 61 and a first hot air transition piece 62 connecting the first tube body 61 with the air storage chamber 31. The first hot air transition piece 62 has a first hot air input port 621 connected to the first tube body 61 and a first hot air output port 622 connected to the bottom of the air storage chamber 31. The first hot air output port 622 opens upward to connect with the bottom surface of the air storage chamber 31.

[0118] When the heating unit 2 transports hot air to the air storage chamber 31 through the first transmission pipe 6, the hot air in the first tube body 61 will be transported to the air storage chamber 31 through the first hot air transition piece 62. The first hot air transition piece 62 serves to connect the first tube body 61 and the air storage chamber 31, thereby improving the tightness of the connection between the first transmission pipe 6 and the air storage chamber 31, and effectively reducing the probability of hot air escaping during the transmission process from the heating unit 2 to the air storage chamber 31, thereby improving the hot air transmission rate of the heating unit 2 to the air outlet unit 3; in addition, the first hot air output port 622 is connected to the bottom surface of the air storage chamber 31, so that the hot air entering the air storage chamber 31 from the first hot air transition piece 62 can gradually accumulate at the bottom of the air storage chamber 31 and fill the air storage chamber 31 from bottom to top, and then be ejected from the air outlet 32, which helps to improve the storage stability of the hot air in the air storage chamber 31.

[0119] As a preferred embodiment of this embodiment, Figure 8As shown, the first hot air input port 621 and the first hot air output port 622 are located on both sides of the first hot air transition piece 62. The first hot air transition piece 62 is provided with two oppositely arranged first air collecting plates 623 near the first hot air input port 621. The two first air collecting plates 623 gradually approach each other from one end of the hot air input port to one end of the first hot air output port 622.

[0120] A first air gathering plate 623 is provided near the first hot air input port 621 of the first hot air transition piece 62, which can gather the hot air entering the first hot air transition piece 62 from the first hot air input port 621. Under the action of the first air gathering plate 623, the movement space of the hot air is gradually reduced, and the hot air moves quickly to the first hot air output port 622 under the push of the subsequent hot air pressure. That is, the setting of the first air gathering plate 623 speeds up the movement speed of the hot air in the first hot air transition piece 62, which helps to improve the hot air transmission efficiency.

[0121] As another preferred embodiment under this embodiment, Figure 8 As shown, the first hot air transition piece 62 is provided with an air induction plate 624 near the first hot air output port 622. The air induction plate 624 is tilted so that the cross-section of the first hot air transition piece 62 gradually increases from the end away from the first hot air output port 622 to the end close to the first hot air output port 622.

[0122] Since the first hot air output port 622 is located at the bottom of the air storage chamber 31, the hot air needs to undergo a change in direction of movement during the movement from the first hot air input port 621 to the first hot air output port 622. Therefore, by providing an air guide plate 624 at the first hot air output port 622, the cross-sectional area of ​​the first hot air transition piece 62 is increased, a larger movement space is provided for the hot air, and the impact of the hot air on the inner wall of the first hot air transition piece 62 during the turning process is reduced. At the same time, the hot air in the first hot air transition piece 62 is guided and turned, thereby improving the smoothness of the hot air discharged from the first hot air output port 622 in multiple aspects.

[0123] As another preferred embodiment of the present application, Figure 9 、 Figure 10 As shown, the de-icing device also 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 with 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 transmits the hot air to the two air outlet units 3 through a first air supply channel 91 and a second air supply channel 92 respectively connected between the air storage box 9 and the two air outlet units 3, and blows the hot air 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 fuselage 1.

[0124] When the heating unit 2 supplies air to the air outlet unit 3, the hot air will first be transported 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 transport hot air to the air storage box 9. Under the action of pressure, the hot air in the air storage box 9 supplies air to the two air outlet units 3 respectively through the symmetrically arranged first air supply channel 91 and the 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 roughly equal, thereby ensuring that the deicing rate of the locking mechanism by the two air outlet units 3 is roughly the same, so that the synchronous deicing of the locking mechanism can be achieved, reducing the probability of one locking mechanism having completed deicing while the other locking mechanism needs to continue deicing due to factors such as the air supply size and temperature difference of the air outlet unit 3, thereby minimizing the dry blowing of hot air to the locking mechanism that has completed deicing.

[0125] As a preferred embodiment of this embodiment, Figures 9 to 12 As shown, the second transmission pipe 7 includes a second tube body 71 and a second hot air transition piece 72 connecting the second tube body 71 with the air storage chamber 31. The second hot air transition piece 72 is arranged below the air outlet unit 3 on the side close to the heating unit 2 and has a second hot air input port 721 connected to the second tube body 71 and a second hot air output port 722 connected to the air storage box 9.

[0126] When the heating unit 2 transports hot air to the air storage box 9 through the second transmission pipe 7, the hot air in the second tube body 71 will be transported to the air storage box 9 through the second hot air transition piece 72. The second hot air transition piece 72 connects the second tube body 71 and the air storage box 9, thereby improving the tightness of the connection between the second transmission pipe 7 and the air storage box 9, and 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 transmission rate of the heating unit 2 to the air storage box 9; in addition, the second hot air transition piece 72 is arranged to pass through below the air outlet unit 3, which can avoid the second hot air transition piece 72 affecting the air supply from the air outlet unit 3 to the locking mechanism.

[0127] As a preferred example under this embodiment, Figure 12As shown, the second hot air input port 721 and the second hot air output port 722 are located on both sides of the second hot air transition piece 72. The second hot air transition piece 72 is provided with two oppositely arranged second air collecting plates 723 near the second hot air input port 721. The two second air collecting plates 723 gradually approach each other from one end of the second hot air input port 721 to one end of the second hot air output port 722. The second hot air input port 721 and the second hot air output port 722 are respectively located on both sides of the second hot air transition piece 72 and a second air gathering plate 723 is provided near the second hot air output port 722, which can gather the hot air entering the second hot air transition piece 72 from the second hot air input port 721. Under the action of the second air gathering plate 723, the movement space of the hot air is gradually reduced, and it moves quickly to the second hot air output port 722 under the push of the subsequent hot air pressure. That is, the setting of the second air gathering plate 723 accelerates the movement speed of the hot air in the second hot air transition piece 72, 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 de-icing device in delivering hot air to the locking mechanism.

[0128] This example does not limit the number and installation method of the air storage boxes 9, and any of the following methods can be used:

[0129] Method 1: If Figure 9 As shown, there is a single air storage box 9, with both ends of the air storage box 9 respectively abutting against the two air outlet units 3 along the length of the fuselage 1. A first air supply channel 91 and a second air supply channel 92 are provided on both sides of the air storage box 9. Providing a single air storage box 9 simplifies the installation of the air storage box 9 between the two air outlet units 3, and the two air outlet units 3 also serve to coordinate and secure the air storage box 9. The first air supply channel 91 and the second air supply channel 92 are provided on both sides of the air storage box 9, increasing the efficiency of hot air delivery from the air storage box 9 to the two air outlet units 3 while reducing mutual interference between the first air supply channel 91 and the second air supply channel 92.

[0130] Method 2: If Figure 10 As shown, there are two air storage boxes 9, spaced apart along the width of the fuselage 1, and the two ends of the air storage boxes 9 along the length of the fuselage 1 are respectively abutted against the two air outlet units 3. Each air storage box 9 is provided with a first air supply channel 91 and a second air supply channel 92 on the side facing the other air storage box 9. Providing two air storage boxes 9 allows the two air outlet units 3 to 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, facilitating the unified assembly of the first air supply channel 91 and the second air supply channel 92.

[0131] Further, if Figure 10As shown, the fuselage 1 is provided with a partition plate 19 at the corresponding air storage box 9, which divides the fuselage 1 into a first installation area 16 and a second installation area 17. The two air supply boxes and the first air supply channel 91 and the second air supply channel 92 respectively connected thereto are installed in the first installation area 16 and the second installation area 17 respectively.

[0132] On the basis of method 1 and method 2, further, Figure 1 、 Figure 2 As shown, the upper and lower surfaces of the fuselage 1 are respectively provided with an upper insulation board 5 and a lower insulation board. The upper insulation board 5 includes a plurality of insulation sub-boards 51. There is a preset gap corresponding to the air outlet unit 3 between two adjacent insulation sub-boards 51 to avoid the air outlet 32. In the length direction of the fuselage 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 is discharged from the gap between the air outlet 32 ​​and the insulation sub-board 51.

[0133] The upper insulation plate 5 can block the heat dissipated upward by the air from the air outlet unit 3 and the air storage box 9, slowing down the heat loss upward 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, and at the same time 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 insulation plate 5 can also carry the melted ice water and ice cubes falling from above, preventing the 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 energy loss to the air outlet unit 3, and at the same time, after the de-icing work is completed, the ice water falling on the upper insulation plate 5 can also be easily collected and processed; in addition, the preset gap between the two adjacent insulation sub-plates 51 also provides a sliding space for the ice water, making the ice water The lower heat insulation member can block the heat dissipated downward by the air from the air outlet unit 3 and the air storage box 9 , thereby slowing down the heat loss downward from the air outlet unit 3 and the air storage box 9 .

[0134] The present application does not limit the structural form of the upper insulation board 5. In another embodiment, the upper insulation board 5 may also be an integral plate-like structure, with a windproof gap provided at the position corresponding to the air outlet unit 3. When the upper insulation board 5 is installed on the upper surface of the fuselage 1, the windproof gap is positioned relative to the air outlet unit 3.

[0135] Preferably, the projection of the lower heat insulation board in the vertical direction covers the air storage box 9 and the air outlet unit 3 .

[0136] Preferably, if Figure 5 、 Figure 18As shown, the heating unit 2 has an exhaust pipe 8 for discharging exhaust gas. The exhaust pipe 8 is drawn from the heating unit 2 and connected to the air storage chamber 31. A filter is provided in the exhaust pipe 8 to filter the exhaust gas. The provision of the exhaust pipe 8 serves to guide the exhaust of smoke generated when the heating unit 2 generates hot air, preventing the smoke from escaping and affecting the de-icing operator. In addition, because the smoke generated by the heating unit 2 when generating hot air is relatively high in temperature, even higher than the hot air temperature, the exhaust pipe 8 is provided to communicate with the air storage chamber 31. The smoke is entrained by the hot air in the air storage chamber 31 and moves toward the locking mechanism, thereby assisting in melting ice. This achieves the recycling of high-temperature smoke and increases the de-icing efficiency of the de-icing device. The filter in the exhaust pipe 8 can filter and intercept solid particles, smoke oil, etc. in the smoke, preventing these solid debris from contaminating the locking mechanism or the battery pack.

[0137] Furthermore, the heating unit 2 may adopt a diesel heater, which has a simple structure, strong adaptability and good heating effect. However, the diesel heater may produce high-temperature exhaust gas containing solid particles such as smoke oil and carbon deposits when working. This part of the 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 the locking mechanism in melting ice.

[0138] As a preferred embodiment of the present application, Figure 13 As shown, along the length direction of the fuselage 1, the fuselage 1 has an active end 11 and a driven end 12 that are relatively arranged. The active end 11 is exerted with a 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 bearing portion 13, and the driven end 12 is provided with a positioning member 100. When the fuselage 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 swap vehicle. When the fuselage 1 completely enters the bottom of the vehicle body and is in place, the positioning member 100 can switch to a vertical state and abut against one side of the vehicle body, and the bearing portion 13 abuts against the other side of the vehicle body so that the air outlet 32 ​​corresponds to the locking mechanism.

[0139] The positioning piece 100 can be matched with the side of the vehicle body after the fuselage 1 is completely entered into the bottom of the vehicle body. When the positioning piece 100 is matched with the vehicle body, the air outlet unit 3 reaches the relative position with the locking mechanism, thereby realizing the precise air supply of the air outlet unit 3 to the locking mechanism. Therefore, the operator can obtain the alignment of the air outlet unit 3 by observing the matching state of the positioning piece 100 with the vehicle body, thereby eliminating the need to observe the relative position of the air outlet unit 3 and the locking mechanism from the bottom of the vehicle body upwards, which greatly reduces the difficulty of the operator in adjusting the position of the de-icing device during the de-icing operation. On the one hand, it shortens the preparation time required for position calibration of the air outlet unit 3 before de-icing, thereby improving the de-icing efficiency. On the other hand, when the positioning piece 100 is matched with the side of the vehicle body, the air outlet unit 3 is in the de-icing position opposite to the locking mechanism, thereby avoiding the position deviation between the air outlet unit 3 and the locking mechanism caused by manual alignment. possibility, thereby further improving the de-icing efficiency of the de-icing device; in addition, the active end 11 and the driven end 12 are respectively arranged on the front and rear sides of the fuselage 1, and the bearing part 13 and the positioning part 100 are respectively arranged at the active end 11 and the driven end 12, on the one hand, it provides a force position for the operator to drive the fuselage 1, and the operator applies the driving force to the bearing part 13 to realize the movement of the fuselage 1, which reduces the difficulty of moving the fuselage 1; in addition, the positioning part 100 and the bearing part 13 are respectively against the two sides of the body of the battery swap vehicle, so that the positioning part 100 and the bearing part 13 can respectively stop the airflow from the side of the body to the bottom of the body, reduce the impact of the airflow on the hot air ejected by the air outlet unit 3, improve the heat supply stability of the air outlet unit 3 to the locking mechanism, and at the same time help to reduce the diffusion of heat from the bottom of the body to the side of the body, which helps to further improve the de-icing speed of the de-icing device.

[0140] Preferably, the heating unit 2 is installed in the carrying portion 13 .

[0141] As a preferred embodiment of this embodiment, Figure 14 As shown, the de-icing device also includes a control mechanism connected to the positioning member 100, the control mechanism includes a first link 110, a second link 120 and a control member 130, the first end 1101 of the first link 110 is rotatably connected to the positioning member 100, the second end 1102 of the first link 110 is rotatably connected to the third end 1201 of the second link 120, and the fourth end 1202 of the second link 120 is rotatably connected to the fuselage 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 link 110 and the second link 120 are rotated, thereby realizing that the positioning member 100 can be switched between a horizontal state and a vertical state.

[0142] The control member 130 can act on the second end 1102 of the first link member 110 and the third end 1201 of the second link member 120 at the same time, and drive the first link member 110 and the second link member 120 to rotate synchronously, so as to realize the switching of the positioning member 100 between the horizontal state and the vertical state, so as to realize the positioning member 100 avoiding the vehicle body or cooperating with the side of the vehicle body; in this process, the first link member 110 and the positioning member 100, the second link member 120 and the positioning member 100, and the first link member 110 and the second link member 120 are all rotationally connected, thereby reducing the control member 130. The control member 130 drives the first linking member 110 and the second linking member 120 to overcome the friction resistance during their movement, thereby making the switching of the positioning member 100 between the horizontal state and the vertical state smoother; in addition, since the first linking member 110 and the second linking member 120 rotate synchronously and approach each other under the drive of the control member 130, the rotation speed of the positioning member 100, that is, the switching speed from the horizontal state to the vertical state, is accelerated, thereby reducing the working stroke of the control member 130 when driving the positioning member 100 to switch positions, which helps to optimize the structural design of the control mechanism.

[0143] Preferably, the air outlet unit 3 extends along the width direction of the fuselage 1 and does not extend beyond the positioning member 100 at either end in the width direction of the fuselage 1. This allows the positioning member 100 to provide maximum shielding of the side space of the air outlet unit 3, thereby improving the positioning member 100's shielding effect on airflow and debris from the side of the vehicle body, and significantly improving the stability of the hot air output of the air outlet unit 3.

[0144] Preferably, if Figure 14 As shown, the positioning member 100 is provided with a flexible anti-collision pad 1001 on the side facing the side of 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 with 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 avoid scratches caused by the abutment between the positioning member 100 and the side of the vehicle body.

[0145] Preferably, if Figure 16 As shown, the control member 130 is a rope, a fixed pulley 150 is provided at the corresponding active end 11 on the fuselage 1, and a limiting shaft 160 is provided at the corresponding driven end 12. The rope is led out from the third connecting member 200, wound around the fixed pulley 150 and extends to the driven end 12, passes through the through hole on the limiting shaft 160, and is connected to the second end 1102 and the third end 1201.

[0146] The control member 130 is set as a rope, so that the control member 130 can adjust its extension direction according to the structural layout of the de-icing device, thereby improving the adaptability of the control member 130 to the de-icing device structure to a high degree. By setting a fixed pulley 150 at the active end 11, the control member 130 is smoothly turned to the extension direction toward the driven end 12 after being led out from the third linking member 200, and when the control member 130 is driven by the third linking member 200 and moves, there is rolling friction between the control member 130 and the fixed pulley 150, and the friction force on the control member 130 is small, which reduces the wear on the control member 130. At the same time, the force required to drive the control member 130 to move through the third connecting member 200 is reduced, so that the operator can more easily drive the first connecting member 110 and the second connecting member 120 to move through the control member 130; in addition, by providing a limit shaft 160 at the driven end 12, the extension direction of the control member 130 toward the first connecting member 110 and the second connecting member 120 can be adjusted by the extension direction of the limit shaft 160, thereby adjusting the force angle of the control member 130 on the second end 1102 and the third end 1201, thereby further optimizing the driving effect of the control member 130 on the positioning member 100.

[0147] Further, if Figure 14 、 Figure 15 As shown, the fuselage 1 is also provided with a plurality of threading conduits 170 spaced apart between the fixed pulley 150 and the limiting shaft 160. The threading conduits 170 are hollowed out to form threading channels 1701 for threading the rope. The plurality of threading conduits 170 disposed on the side of the fuselage 1 and the threading channels 1701 formed by the plurality of threading conduits 170 cooperate to provide a fixed guide for the extension of the control member 130 at the active end 11 and the driven end 12. This allows the control member 130 to extend and retract along the extension direction of the threading channels 1701 under the drive of the third linking member 200, thereby preventing the control member 130 from shifting.

[0148] As a preferred example under this embodiment, Figure 14 As shown, an elastic return member is provided between the positioning member 100 and the fuselage 1, and the elastic return 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 return 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 return member keeps the positioning member 100 in a vertical state or switches from a horizontal state to a vertical state.

[0149] When the fuselage 1 is completely pushed into the bottom of the vehicle body, the operator only needs to cancel the force applied to the control member 130, and the positioning member 100 will switch from the horizontal state to the vertical state under the elastic action of the elastic return member, eliminating the operator's need to switch the position of the positioning member 100 from the horizontal state to the vertical state, thereby achieving rapid coordination between the positioning member 100 and the side of the vehicle body; in addition, the elastic force of the elastic return member can also maintain the positioning member 100 in the vertical state. During the de-icing process of the de-icing device, the operator does not need to apply additional force to maintain the state of the positioning member 100, thereby optimizing the user experience of the de-icing device.

[0150] Preferably, if Figure 14 As shown, the elastic return member is a spring hinge 140, which 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 return member is set as a spring hinge 140, and is fixedly connected to the positioning member 100 and the body 1 through the first leaf 1401 and the second leaf 1402, respectively. This increases the contact area between the elastic return member, the positioning member 100, and the body 1, so that the elastic return member can provide more stable support for the positioning member 100. The spring applies elastic force to the first leaf 1401 and the second leaf 1402, maintaining the angle between the first leaf 1401 and the second leaf 1402, thereby maintaining the angle between the positioning member 100 and the body 1.

[0151] As another preferred example under this embodiment, Figure 16 、 Figure 17 As shown, there are two first connecting members 110, two second connecting members 120 and two control members 130, which are symmetrically arranged at the two ends of the positioning member 100 along the length direction of the vehicle body. The control mechanism also includes a synchronization 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 connecting members 200, which are arranged at the two ends of the synchronization shaft 180 along the width direction of the vehicle body and are respectively connected to the control members 130 at the corresponding ends, and the control rod 190 is fixed to the synchronization shaft 180.

[0152] The number of the first linking member 110, the second linking member 120 and the control member 130 is set to two, and they are respectively arranged at both ends of the positioning member 100, so that the rotational force applied to the positioning member 100 is more uniform, and the force pressure of the single control member 130 to drive the positioning member 100 to rotate is reduced; in addition, since a synchronous shaft 180 is provided and the two control members 130 are connected to the synchronous shaft 180, the operator only needs to apply a force to the synchronous shaft 180, and the synchronous shaft 180 drives the two control members 130 to move at the same time by rotating to drive the positioning members 100 to rotate respectively. The first linking member 110 and the second linking member 120 on both sides of 100 save the operation of driving the two control members 130 to work at the same time, reduce the difficulty of the operator's work, and optimize the structural design of the de-icing device; furthermore, since the end of the third linking member 200 away from the synchronization shaft 180 is connected to the control member 130, only a small rotation angle of the synchronization shaft 180 is required to drive the third linking member 200 away from the end of the synchronization shaft 180 to have a large stroke, thereby achieving a large stroke change of the control member 130 connected to the third linking member 200, and then through The first link 110 and the second link 120 drive the positioning member 100 to move; that is, the positioning member 100 can be driven to switch from the vertical state to the horizontal state by a relatively small rotation of the synchronization shaft 180, which reduces the working space required for the control mechanism to drive the positioning member 100 to move, and contributes to the miniaturization of the deicing device. At the same time, the operator only needs a relatively small force stroke to drive the positioning member 100 to move to the horizontal state, thereby optimizing the structural design of the deicing device. Furthermore, since the rotation trajectory of the synchronization shaft 180 is fixed, the third link 200 rotates with the synchronization shaft 180. The synchronous rotation trajectory that occurs in turn is also fixed, thereby ensuring that the movement trajectory of the control member 130 connected to the third link 200 is constant. Therefore, by rotating the synchronization shaft 180, the two control members 130 can be moved along the fixed trajectory to drive the positioning member 100 to switch from the vertical state to the horizontal state, avoiding the occurrence of the control member 130's force deviation on the first link 110 and the second link 120 due to the operator's force deviation or other factors, and providing a guarantee for the stability of the positioning member 100 in the process of switching from the vertical state to the horizontal state.
