Description

Technical Field

[0001] This application pertains to the field of new energy vehicles, specifically relating to a split-type de-icing device. Background Technology

[0002] In daily life, cars are becoming increasingly common, and the widespread use of gasoline-powered vehicles not only exacerbates the consumption of non-renewable resources but also pollutes the environment with exhaust emissions. Faced with the growing imbalance between supply and demand for traditional energy sources and the severe situation of global warming, electric vehicles (EVs) have emerged as a new energy mode of transportation. Due to their advantages such as low noise, high energy efficiency, and zero mobile exhaust emissions, EVs have become one of the strategic emerging industries that many countries prioritize. However, as EVs enter the market, driving range has become a significant factor hindering their development. Drawing inspiration from the traditional method of using refueling to extend the driving range of cars, for EVs, charging depleted battery packs or directly replacing them with fully charged ones has become a key research and development direction for increasing the driving range of EVs.

[0003] Due to limitations in battery material and charging technologies, new energy vehicles require at least tens of minutes to fully charge after running out of power. For some new energy freight vehicles with large battery packs, this charging time is even longer, significantly impacting the user's driving experience. This is especially true for commercial vehicle owners, as waiting for charging means reduced working hours. The time required to replace the battery pack is much shorter than the charging time. Therefore, more and more new energy vehicles are adopting detachable battery packs for energy supply, solving the disadvantages of long charging times and inconvenience associated with fixed battery packs. Specifically, multiple locking mechanisms need to be installed on the bottom of the vehicle. The installation or removal of the battery pack is achieved by locking or unlocking the locking mechanisms and mating parts on the battery pack. Furthermore, for these new energy vehicles, due to the large weight and volume of the battery pack, specialized battery swapping equipment is required for disassembly and installation. However, in cold northern weather, especially after heavy snow or rain, the undercarriage can be covered with a thick layer of ice. This ice can also encase the locking mechanisms, affecting unlocking and causing the battery pack to be frozen to the bottom of the vehicle, making it difficult or even impossible to remove. This will greatly increase the battery swapping time for vehicles, leading to congestion at battery swapping stations.

[0004] Therefore, before replacing the battery pack, a de-icing device is needed to melt the ice layer on the locking mechanism. New energy vehicles generally use locking mechanisms distributed on both sides of the battery pack to fix the battery pack to the bottom of the vehicle. When de-icing the locking mechanism, it takes a long time to de-ic the locking mechanisms on both sides of the battery pack separately. The speed of de-icing directly affects the time required for the entire battery swapping process, and the battery swapping time is the most critical factor determining the user's battery swapping experience. Therefore, how to design a de-icing device that can quickly melt ice has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

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

[0006] The technical solution adopted in this application is as follows:

[0007] A split-type de-icing device is used for de-icing battery swapping vehicles. The battery pack of the battery swapping vehicle is installed at the bottom of the vehicle body via a locking mechanism to facilitate quick battery pack swapping. The de-icing device includes a first body and a second body. The first body is provided with a first air outlet unit and a first heating unit that supplies hot air to the first air outlet unit. The second body is provided with a second air outlet unit and a second heating unit that supplies hot air to the second air outlet unit. The first air outlet unit and the second air outlet unit are respectively disposed corresponding to the locking mechanism on the corresponding side of the battery pack. The first body and the second body can be moved from both sides in the width direction of the battery swapping vehicle to the bottom of the vehicle body so that the first air outlet unit and the second air outlet unit are respectively aligned with the corresponding locking mechanism.

[0008] By adopting the above technical solution, when de-icing the locking mechanism at the bottom of the battery swapping vehicle, the first and second units are pushed into the bottom of the vehicle from the sides, respectively, aligning the first and second air outlet units with their corresponding locking mechanisms. Hot air is then supplied to the first and second air outlet units via the first and second heating units, respectively, thus simultaneously de-icing the corresponding locking mechanisms. This helps shorten the de-icing time of the battery swapping vehicle and improves the user experience. Furthermore, since the first and second units are pushed into the bottom of the vehicle from the sides, the de-icing process is reduced. Regarding the space requirements on one side of the battery swapping vehicle, the de-icing device of this application can adapt well to situations where the vehicle body is wide or the space of the battery swapping station is small, resulting in a compact space on one side of the vehicle. This improves the adaptability to charging stations of different sizes and vehicles of different volumes. Furthermore, since the first and second units are pushed in from both sides of the vehicle body, the movement paths required for the first and second units to align with the locking mechanism are shortened, as are the movement paths for the first and second units to be pulled out from the bottom of the vehicle body after the de-icing work is completed, thus increasing the de-icing efficiency.

[0009] The first body and / or the second body can be positioned on the corresponding side of the vehicle body of the battery swapping vehicle to achieve alignment between the first air outlet unit and / or the second air outlet unit and the corresponding locking mechanism.

[0010] By adopting the above technical solution, when the first and second bodies move towards the bottom of the vehicle body, once the first and / or second bodies are positioned with the battery swapping vehicle body, the operator can know that the first and / or second air outlet units have been aligned with the locking mechanism, without needing to observe the alignment of the first and / or second air outlet units with the locking mechanism from below the vehicle body. This greatly reduces the difficulty of aligning the first and / or second air outlet units with the locking mechanism, thereby significantly reducing the preparation time required before the de-icing work begins. At the same time, it avoids the possibility of misalignment between the first and / or second air outlet units and the locking mechanism due to difficulties in observation or limited observation positions for the operator, improving the de-icing accuracy of the de-icing device on the locking mechanism and further reducing the de-icing time.

[0011] The first body has a first baffle on the side not extending into the bottom of the battery swapping vehicle, and the second body has a second baffle on the side not extending into the bottom of the battery swapping vehicle. The first body has a first connector on the side away from the first baffle, and the second body has a second connector adapted to the first connector on the side away from the second baffle. When the first body and the second body are pushed into the bottom of the battery swapping vehicle, the first baffle and the second baffle abut against the corresponding sides of the battery swapping vehicle, and the first connector and the second connector are connected to each other to lock the relative positions of the first body and the second body, thereby aligning the first air outlet unit and the second air outlet unit with the corresponding locking mechanism.

[0012] By adopting the above technical solution, and by setting the first baffle and the second baffle, on the one hand, the first body and the second body respectively cooperate with the vehicle body to position the first air outlet unit and the second air outlet unit. On the other hand, since the first baffle and the second baffle abut against the side of the vehicle body, in the width direction of the first body and the second body, the height gaps from the bottom of the vehicle body to the first body and from the bottom of the vehicle body to the second body are blocked by the first baffle and the second baffle. This can stop the airflow from the side of the vehicle body to the bottom of the vehicle body, reduce the impact of the airflow on the hot air ejected from the first air outlet unit and the second air outlet unit, improve the heat supply stability of the first air outlet unit and the second air outlet unit to the locking mechanism, and at the same time help to reduce the vehicle body temperature. The diffusion of heat from the bottom of the body to the side of the vehicle helps to further improve the de-icing speed of the de-icing device. In addition, by setting the first and second connecting parts, after the first and second bodies are pushed into place, the first and second baffles must be fully attached to the side of the vehicle body to achieve the connection of the first and second connecting parts. This ensures that the extension direction of the first and second air outlet units is consistent with the extension direction of the locking mechanism. This avoids the occurrence of angular deviation between the first and / or second air outlet units and the locking mechanism due to the misalignment of the first and / or second bodies and the vehicle body, thus providing further assurance for the de-icing accuracy of the de-icing device.

[0013] The first baffle has a first flexible pad on the side facing the first connector, and / or the second baffle has a second flexible pad on the side facing the second connector.

[0014] By adopting the above technical solution, when the first and second bodies move to the bottom of the battery swapping vehicle, the first and second baffles abut against the sides of the vehicle body respectively. By setting the first and second flexible pads, the impact force when the first and second baffles abut against the battery swapping vehicle body can be reduced, thereby achieving a relatively gentle abutment between the first and second baffles and the battery swapping vehicle body, reducing the probability of the first and second baffles or the vehicle body being deformed due to excessive speed of movement of the first and second bodies.

[0015] The first body is a U-shaped frame, including a first bottom beam and two first extension arms disposed at both ends of the first bottom beam. The first baffle extends upward from the top surface of the first bottom beam. The first connector is disposed at the end of the first extension arm away from the first bottom beam. The first air outlet unit is connected between the two first extension arms. And / or, the second body is a U-shaped frame, including a second bottom beam and two second extension arms disposed at both ends of the second bottom beam. The second baffle extends upward from the top surface of the second bottom beam. The second connector is disposed at the end of the second extension arm away from the second bottom beam. The second air outlet unit is connected between the two second extension arms.

[0016] By adopting the above technical solution, the two first extension arms and the two second extension arms provide installation and load-bearing functions for the first air outlet unit and the second air outlet unit, respectively. The two first extension arms jointly support the first air outlet unit, making the installation of the first air outlet unit more stable and reducing the risk of the first air outlet unit shaking or swaying due to the impact of hot air during operation. The same applies to the second air outlet unit. In addition, setting the first and second bodies into a U-shaped frame can make the center of gravity of the first and second bodies more stable, improve their stability during movement, and prevent the first and second bodies from moving off-center due to the shift of the center of gravity. The first connector and the second connector are respectively set at the ends of the first extension arms and the second extension arms. When the first body and the second body are docked, the two connection points make the connection between the first body and the second body more stable.

[0017] The first bottom beam is provided with a first clearance hole, and the first heating unit is installed on the first bottom beam and transmits hot air to the first air outlet unit through a first transmission pipe passing through the first clearance hole; and / or, the second bottom beam is provided with a second clearance hole, and the second heating unit is installed on the second bottom beam and transmits hot air to the second air outlet unit through a second transmission pipe passing through the second clearance hole.

[0018] By adopting the above technical solution, the first bottom beam, in addition to its function of cooperating with the first extension arm to form the first body, further integrates the function of accommodating the first heating unit. This results in a high degree of functional integration, optimizes the structural design of the de-icing device, and eliminates the need for separate installation positions for the first heating unit in other locations on the first body, thus contributing to the miniaturization of the first body. Similarly, the second bottom beam, in addition to its function of cooperating with the second extension arm to form the second body, further integrates the function of accommodating the second heating unit. This also results in a high degree of functional integration, optimizes the structural design of the de-icing device, and eliminates the need for separate installation positions for the second heating unit in other locations on the second body, thus contributing to the miniaturization of the second body.

[0019] There are two first heating units, which are spaced apart along the length of the battery pack and are each connected to the first air outlet unit through a corresponding first transmission pipe; and / or, there are two second heating units, which are spaced apart along the length of the battery pack and are each connected to the second air outlet unit through a corresponding second transmission pipe.

[0020] By adopting the above technical solution, the number of the first heating unit and the second unit is set to two, and air is supplied to the first air outlet unit and the second air outlet unit through two first transmission pipes and two second transmission pipes respectively. On the one hand, the heating efficiency of the first heating unit and the second air outlet unit can be improved, and the amount of hot air delivered to the first air outlet unit and the second air outlet unit can be increased, thereby realizing rapid de-icing of the locking mechanism. On the other hand, the air supply to the first air outlet unit and the second air outlet unit can be made more uniform, thereby improving the uniformity of the air supply to the locking mechanism by the first air outlet unit and the second air outlet unit.

[0021] The first heating unit further includes a flue pipe, which is disposed on one side of the first transmission pipe and communicates with the first air outlet unit; and / or, the second heating unit further includes a flue pipe, which is disposed on one side of the second transmission pipe and communicates with the second air outlet unit.

[0022] By adopting the above technical solution, the exhaust pipe serves to guide and discharge the smoke generated when the first and second heating units produce hot air, preventing the smoke from spreading and affecting the de-icing operators. In addition, since the smoke generated by the first and second heating units when producing hot air is at a high temperature, even higher than the temperature of the hot air, the exhaust pipe is connected to the first and / or second air outlet units. The smoke moves towards the locking mechanism under the influence of the hot air, thus assisting in the de-icing process. This achieves the recycling of high-temperature smoke and increases the de-icing efficiency of the de-icing device.

[0023] The first air outlet unit does not extend beyond the first baffle at either end in the length direction of the battery pack, and the second air outlet unit does not extend beyond the second baffle at either end in the length direction of the battery pack.

[0024] By adopting the above technical solution, the first air outlet unit and the second air outlet unit are configured such that their two ends in the length direction of the battery pack do not exceed the first baffle and the second baffle, so that the first baffle and the second baffle can act as a windbreak for the first air outlet unit and the second air outlet unit in the width direction of the vehicle body, thereby reducing the airflow interference of the airflow moving laterally along the vehicle body on the first air outlet unit and the second air outlet unit, and effectively improving the stability of the hot air direction locking mechanism during its movement.

[0025] The first and second air outlet units are both provided with air outlets at their tops; the locking mechanisms are arranged in two rows along the length of the battery pack on both sides of the battery pack, and the air outlets extend from one end of the air outlet unit to the other end along the length of the battery pack; or, there are multiple locking mechanisms arranged on the battery pack at preset positions, and there are multiple air outlets, with the multiple air outlets corresponding to the positions of each locking mechanism.

[0026] By adopting the above technical solution, placing the air outlets at the top of the first and second air outlet units can shorten the distance between the air outlets and the locking mechanism, reducing the travel time of hot air between the air outlets and the locking mechanism. This helps to shorten the heat loss during the movement of hot air from the air outlets towards the locking mechanism, improving the de-icing efficiency of the de-icing device. Furthermore, arranging the locking mechanism in two rows allows for a more stable installation of the battery pack, and setting the air outlets to extend along the length of the battery pack allows for better airflow from the storage unit. The hot air ejected from the air chamber can provide uniform air supply to the locking mechanisms located on the side along the length of the battery pack, improving the uniformity of air supply to each locking mechanism by the de-icing device. This ensures that the ice layer at each locking mechanism is heated evenly and the melting time is approximately equal. Furthermore, by setting multiple air outlets and aligning them with each locking mechanism, the air outlet unit achieves higher de-icing precision for the locking mechanisms. Each air outlet supplies air to its corresponding locking mechanism, improving the utilization efficiency of hot air while ensuring uniform air supply, thus increasing the de-icing efficiency of the de-icing device.

[0027] Both the first air outlet unit and the second air outlet unit have hollow interiors to form an air storage cavity. The bottom or side of the air storage cavity is connected to the first heating unit or the second heating unit, and the air outlet is located at the top of the air storage cavity.

[0028] By adopting the above technical solution, since the air outlet unit is equipped with an air storage cavity, during the process of the first heating unit and the second heating unit respectively delivering hot air to the first air outlet unit and the second air outlet unit, the hot air will first gather in the air storage cavity. After the air storage cavity is full of hot air, as the first heating unit and the second heating unit continue to inject hot air into the air storage cavity, the air pressure in the air storage cavity continuously increases. Under the action of pressure, the hot air in the air storage cavity is ejected from the air outlet. The power source driving the hot air to move towards the locking mechanism is the continuously increasing air pressure in the air storage cavity. Since the air outlet is located at the top of the air storage cavity, the air pressure driving force driving the hot air to move towards the air outlet is from bottom to top, so that the hot air reaches the locking mechanism located above the air outlet under the action of the bottom-up driving force. That is, by setting up an air storage cavity, the requirements for the direction of hot air delivery of the first heating unit and the heating unit are reduced, and the turbulent airflow is regulated, improving the movement accuracy of the hot air, thereby helping to improve the de-icing efficiency.

[0029] The air storage cavity has a first top surface and a second top surface that are spaced apart. The gap between the first top surface and the second top surface forms the air outlet. Both the first top surface and the second top surface are inclined and gradually extend from top to bottom in a direction that moves away from each other.

[0030] By adopting the above technical solution, the hot air supplied to the air storage cavity by the first heating unit and the second heating unit moves randomly in the air storage cavity under the action of kinetic energy, and the mutual impact between the hot air makes the movement direction of the hot air more chaotic. By setting the first top surface and the second top surface, the hot air in the air storage cavity can be guided. Under the guidance of the first top surface and the second top surface, the hot air gradually converges in the direction close to the air outlet. During the convergence of the hot air towards the air outlet, its movement direction is continuously adjusted by the action of the first top surface and the second top surface. This allows the hot air to move towards the locking mechanism after reaching the air outlet, reducing the probability of the hot air escaping in all directions after being ejected from the air outlet due to the deviation in the movement direction, thereby further improving the de-icing efficiency of the de-icing device.

[0031] The top of the air outlet is provided with two air expansion plates, which are respectively arranged on both sides of the air outlet and extend from bottom to top in a direction that gradually moves away from each other.

[0032] By adopting the above technical solution, due to the installation of the air diffuser, after the hot air is ejected from the air outlet, part of the hot air continues to move vertically upwards, while part of the hot air tends to move obliquely due to changes in air pressure. This part of the hot air with the oblique movement tendency 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. In addition, when the ice layer above the air outlet is melted, the melted water droplets will... The water drips downwards under its own weight, and the hot air at the air outlet has high thermal energy, which can instantly evaporate the water droplets into water vapor. The air diffuser can collect the melted water on the side of the air outlet, so that the water droplets dripping on the air diffuser move along the air diffuser towards the air outlet under their own weight and are quickly evaporated into water vapor under the action of hot air. This reduces the probability of melted water dripping onto the first air outlet unit, the second air outlet unit or other components and interfering with the components of the de-icing device. Therefore, by setting up the air diffuser, more of the ice layer removed by the de-icing device is released in the form of water vapor, reducing the pressure on the collection and treatment of melted water.

[0033] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0034] When de-icing the locking mechanisms at the bottom of the battery swapping vehicle, the first and second units are pushed into the bottom of the vehicle from the sides, aligning the first and second air outlet units with the two rows of locking mechanisms. Hot air is then supplied to the first and second air outlet units via the first and second heating units, respectively, allowing for simultaneous de-icing of both rows of locking mechanisms. This helps shorten the de-icing time and improves the user experience. Furthermore, because the first and second units are pushed into the bottom of the vehicle from the sides, the impact on the de-icing device is reduced. The de-icing device of this application can better adapt to the limited space on one side of the vehicle body, especially in situations where the vehicle body is wide or the space of the battery swapping station is small, thus improving its adaptability to charging stations of different sizes and vehicles of different volumes. Furthermore, since the first and second units are pushed in from both sides of the vehicle body, the movement paths required for the first and second units to align with the locking mechanism are shortened, as are the movement paths for the first and second units to be pulled out from the bottom of the vehicle body after the de-icing work is completed, thereby increasing the de-icing efficiency.

[0064] like Figure 1 , Figure 2 , Figure 6 As shown, a split-type de-icing device is used for de-icing a battery swapping vehicle. The battery pack of the battery swapping vehicle is installed at the bottom of the vehicle body through a locking mechanism to facilitate quick battery pack replacement. The de-icing device includes a first body 1 and a second body 2. The first body 1 is provided with a first air outlet unit 3 and a first heating unit 5 for supplying hot air to the first air outlet unit 3. The second body 2 is provided with a second air outlet unit 4 and a second heating unit 6 for supplying hot air to the second air outlet unit 4. The first air outlet unit 3 and the second air outlet unit 4 are respectively arranged corresponding to the locking mechanism on the corresponding side of the battery pack, that is, they extend along the width direction of the first body 1 and the second body 2 respectively. The first body 1 and the second body 2 can be moved from both sides of the width direction of the battery swapping vehicle to the bottom of the vehicle body so that the first air outlet unit 3 and the second air outlet unit 4 are respectively aligned with the corresponding locking mechanism.

[0065] Figure 6 The middle arrow Y points to the length of the battery swapping vehicle 150, and the arrow X points to the direction of movement of the de-icing device into the bottom of the battery swapping vehicle 220. The first unit 1 and the second unit 2 enter the bottom of the battery swapping vehicle 220 along both sides of the vehicle. When de-icing the locking mechanisms at the bottom of the battery swapping vehicle, the first unit 1 and the second unit 2 are pushed into the bottom of the vehicle from the sides, aligning the first air outlet unit 3 and the second air outlet unit 4 with the two rows of locking mechanisms. Hot air is then supplied to the first air outlet unit 3 and the second air outlet unit 4 through the first heating unit 5 and the second heating unit 6, respectively, thus achieving simultaneous de-icing of the two rows of locking mechanisms. This helps to shorten the de-icing time of the battery swapping vehicle and improve the user experience. Furthermore, the... The first body 1 and the second body 2 are pushed into the bottom of the vehicle body from both sides, reducing the space requirements of the de-icing device on one side of the vehicle body. For situations where the vehicle body is wide or the space of the battery swapping station is small, resulting in a compact space on one side of the vehicle body, the de-icing device of this application can adapt well, improving the adaptability to charging stations of different sizes and vehicles of different volumes. Furthermore, since the first body 1 and the second body 2 are pushed in from both sides of the vehicle body, the movement path required for the first body 1 and the second body 2 to align with the locking mechanism is shortened, as is the movement path for the first body 1 and the second body 2 to be pulled out from the bottom of the vehicle body after the de-icing work is completed, thus increasing the de-icing efficiency.

[0066] Preferably, both the first body 1 and the second body 2 are provided with casters at the bottom, and the first body 1 and the second body 2 are also provided with handrails on the side facing away from each other. The first body 1 and the second body 2 are pushed from the sides of the battery swapping vehicle to the bottom of the vehicle body by the handrails.

[0067] This application does not limit the positional relationship between the first body 1, the second body 2, and the vehicle body, and it can adopt any of the following embodiments:

[0068] Implementation Method 1: The first body 1 can be positioned on the corresponding side of the battery swapping vehicle body to align the first air outlet unit 3 with the corresponding locking mechanism. During the movement of the first body 1 towards the bottom of the vehicle body, once the first body 1 is positioned with the battery swapping vehicle body, the operator can immediately know that the first air outlet unit 3 is aligned with the locking mechanism, without needing to observe the alignment from below the vehicle body. This significantly reduces the difficulty of aligning the first air outlet unit 3 with the locking mechanism, thereby greatly reducing the preparation time required before the de-icing operation begins. Simultaneously, it avoids the possibility of misalignment between the first air outlet unit 3 and the locking mechanism due to difficulties in observation or limited observation positions for the operator, improving the de-icing accuracy of the de-icing device on the locking mechanism and further reducing the de-icing time.

[0069] Implementation Method 2: The second body 2 can be positioned on the corresponding side of the battery swapping vehicle body to align the second air outlet unit 4 with the corresponding locking mechanism. During the movement of the second body 2 towards the bottom of the vehicle body, once the second body 2 is positioned with the battery swapping vehicle body, the operator can immediately know that the second air outlet unit 4 is aligned with the locking mechanism, without needing to observe the alignment from below the vehicle body. This significantly reduces the difficulty of aligning the second air outlet unit 4 with the locking mechanism, thereby greatly reducing the preparation time required before the de-icing operation begins. Simultaneously, it avoids the possibility of misalignment between the second air outlet unit 4 and the locking mechanism due to difficulties in observation or limited observation positions for the operator, improving the de-icing accuracy of the de-icing device on the locking mechanism and further reducing the de-icing time.

[0070] Implementation Method 3: The first and second bodies 2 can be positioned on the corresponding sides of the battery swapping vehicle body to align the first air outlet unit 3 and the second air outlet unit 4 with the corresponding locking mechanism. When the first body 1 and the second body 2 move towards the bottom of the vehicle body, once they are positioned, the operator can immediately know that the first air outlet unit 3 and the second air outlet unit 4 are aligned with the locking mechanism, without needing to observe their alignment from below. This significantly reduces the difficulty of aligning the first air outlet unit 3 and the second air outlet unit 4 with the locking mechanism, thereby greatly reducing the preparation time required before de-icing. Simultaneously, it avoids the possibility of misalignment between the first air outlet unit 3 and the second air outlet unit 4 and the locking mechanism due to operator observation difficulties or limited observation positions, improving the de-icing accuracy of the de-icing device on the locking mechanism and further reducing the de-icing time.

[0071] As a preferred embodiment of implementation methods one to three, such as Figure 1 , Figure 2 As shown, the first body 1 has a first baffle 11 on the side not inserted into the bottom of the battery swapping vehicle body, and the second body 2 has a second baffle 21 on the side not inserted into the bottom of the battery swapping vehicle body. The first body 1 is provided with a first connector 12 on the side away from the first baffle 11, and the second body 2 is provided with a second connector 22 adapted to the first connector 12 on the side away from the second baffle 21. When the first body 1 and the second body 2 are respectively pushed into the bottom of the battery swapping vehicle body, the first baffle 11 and the second baffle 21 respectively abut against the corresponding side of the battery swapping vehicle body, and the first connector 12 and the second connector 22 are connected to each other to lock the relative position of the first body 1 and the second body 2, thereby realizing the alignment of the first air outlet unit 3 and the second air outlet unit 4 with the corresponding locking mechanism.

[0072] By setting the first baffle 11 and the second baffle 21, on the one hand, the first body 1 and the second body 2 respectively cooperate with the vehicle body to position the first air outlet unit 3 and the second air outlet unit 4. On the other hand, the first baffle 11 and the second baffle 21 can also block the airflow from the side of the vehicle body to the bottom of the vehicle body, reducing the impact of the airflow on the hot air ejected from the first air outlet unit 3 and the second air outlet unit 4, improving the heat supply stability of the first air outlet unit 3 and the second air outlet unit 4 to the locking mechanism, and at the same time helping to reduce the diffusion of heat from the bottom of the vehicle body to the side of the vehicle body, which helps to further improve the de-icing speed of the de-icing device; in addition, by setting When the first body 1 and the second body 2 are pushed into place, the first baffle 11 and the second baffle 21 need to be fully fitted with the side of the vehicle body to connect the first connector 12 and the second connector 22. This ensures that the extension direction of the first air outlet unit 3 and the second air outlet unit 4 is consistent with the extension direction of the locking mechanism. This avoids the occurrence of angular deviation between the first air outlet unit 3 and the second air outlet unit 4 and the locking mechanism due to the misalignment of the movement direction of the first body 1 and the second body 2, which would cause them to come into contact with the vehicle body. This provides further assurance for the de-icing accuracy of the de-icing device.

[0073] Preferably, the first connector 12 is a first magnetic body with magnetism, and the second connector 22 is a second magnetic body with magnetism opposite to that of the first connector 12. The first connector 12 and the second connector 22 are magnetically attracted to lock the relative positions of the first body 1 and the second body 2.

[0074] This embodiment does not limit the structural form of the first baffle 11 and the second baffle 21. In one preferred embodiment, the first baffle 11 is provided with a first flexible pad on the side facing the first connector 12; in another preferred embodiment, the second baffle 21 is provided with a second flexible pad on the side facing the second connector 22; in yet another preferred embodiment, the first baffle 11 is provided with a first flexible pad on the side facing the first connector 12, and the second baffle 21 is provided with a second flexible pad on the side facing the second connector 22.

[0075] When the first body 1 and the second body 2 move to the bottom of the battery swapping vehicle, the first baffle 11 and the second baffle 21 abut against the side of the vehicle body respectively. By setting the first flexible pad and the second flexible pad, the impact force when the first baffle 11 and the second baffle 21 abut against the battery swapping vehicle body can be reduced. This achieves a relatively gentle abutment between the first baffle 11 and the second baffle 21 and the battery swapping vehicle body, reducing the probability of the first baffle 11, the second baffle 21 or the vehicle body being deformed due to the excessive speed of the first body 1 and the second body 2.

[0076] This embodiment does not limit the structural form of the first and second bodies, and they can adopt any of the following examples:

[0077] Example 1: such as Figures 1 to 3 As shown, the first body 1 is a U-shaped frame, including a first bottom beam 13 and two first extension arms 14 disposed at both ends of the first bottom beam 13. A first baffle 11 extends upward from the top surface of the first bottom beam 13. A first connector 12 is disposed at the end of the first extension arm 14 away from the first bottom beam 13. A first air outlet unit 3 is connected between the two first extension arms 14.

[0078] Example 2: such as Figures 1 to 3 As shown, the second body 2 is a U-shaped frame, including a second bottom beam 23 and two second extension arms 24 disposed at both ends of the second bottom beam 23. The second baffle 21 extends upward from the top surface of the second bottom beam 23. The second connector 22 is disposed at the end of the second extension arm 24 away from the second bottom beam 23. The second air outlet unit 4 is connected between the two second extension arms 24.

[0079] Example 3: such as Figures 1 to 3As shown, the first body 1 is a U-shaped frame, including a first bottom beam 13 and two first extension arms 14 disposed at both ends of the first bottom beam 13. A first baffle 11 extends upward from the top surface of the first bottom beam 13. A first connector 12 is disposed at the end of the first extension arm 14 away from the first bottom beam 13. A first air outlet unit 3 is connected between the two first extension arms 14. The second body 2 is a U-shaped frame, including a second bottom beam 23 and two second extension arms 24 disposed at both ends of the second bottom beam 23. A second baffle 21 extends upward from the top surface of the second bottom beam 23. A second connector 22 is disposed at the end of the second extension arm 24 away from the second bottom beam 23. A second air outlet unit 4 is connected between the two second extension arms 24. The two first extension arms 14 and the two second extension arms 24 provide installation and load-bearing functions for the first air outlet unit 3 and the second air outlet unit 4, respectively. The two first extension arms 14 jointly support the first air outlet unit 3, making the installation of the first air outlet unit 3 more stable and reducing the risk of the first air outlet unit 3 shaking or swaying due to the impact of hot air during operation. The same applies to the second air outlet unit 4. In addition, setting the first body 1 and the second body 2 into a U-shaped frame can make the center of gravity of the first body 1 and the second body 2 more stable, improve their stability during movement, and prevent the first body 1 and the second body 2 from moving off course due to the shift of the center of gravity. The first connector 12 and the second connector 22 are respectively set at the ends of the first extension arm 14 and the second extension arm 24. When the first body 1 and the second body 2 are docked, the two connection points make the connection between the first body 1 and the second body 2 more stable.

[0080] In the above example, the first bottom beam 13 is arranged parallel to the first air outlet unit 3, and the distance between them corresponds to the distance between the side of the vehicle body and the corresponding locking mechanism; the second bottom beam 23 is arranged parallel to the second air outlet unit 4, and the distance between them also corresponds to the distance between the side of the vehicle body and the corresponding locking mechanism. This arrangement ensures that when the first baffle 11 and the second baffle 21 abut against the side of the vehicle body, the first air outlet unit 3 and the second air outlet unit 4 can correspond to the locking mechanism on the corresponding side. Furthermore, when the first connecting member 12 and the second connecting member 22 cooperate, the first body 1 and the second body 2 can be further adjusted to further ensure the accuracy of the position of the first air outlet unit 3 and the second air outlet unit 4 relative to the corresponding locking mechanism. Preferably, as follows... Figure 1 , Figure 2 As shown, the first extension arm 14 is perpendicular to the first bottom beam 13, and the second extension arm 24 is perpendicular to the second bottom beam 23. This makes the extension directions of the first extension arm 14 and the second extension arm 24 lie on the same horizontal line, which helps to reduce the connection difficulty of the first connector 12 and the second connector 22, thereby improving the alignment stability of the first body 1 and the second body 2.

[0081] The above example does not limit the structural form of the first and second bottom beams, which can adopt any of the following preferred methods:

[0082] Method 1: For example Figure 1 , Figure 2 As shown, the first bottom beam 13 is provided with a first clearance hole 131, and the first heating unit 5 is installed on the first bottom beam 13 and transmits hot air to the first air outlet unit 3 through the first transmission pipe 7 passing through the first clearance hole 131.

[0083] Method 2: For example Figure 1 , Figure 2 As shown, the second bottom beam 23 is provided with a second clearance hole 231, and the second heating unit 6 is installed on the second bottom beam 23 and transmits hot air to the second air outlet unit 4 through the second transmission pipe 8 passing through the second clearance hole 231.

[0084] Method 3: For example Figure 1 , Figure 2 As shown, the first bottom beam 13 is provided with a first clearance hole 131, the first heating unit 5 is installed on the first bottom beam 13 and transmits hot air to the first air outlet unit 3 through the first transmission pipe 7 passing through the first clearance hole 131, the second bottom beam 23 is provided with a second clearance hole 231, the second heating unit 6 is installed on the second bottom beam 23 and transmits hot air to the second air outlet unit 4 through the second transmission pipe 8 passing through the second clearance hole 231. The first bottom beam 13, in addition to its function of cooperating with the first extension arm 14 to form the first body 1, further integrates the function of accommodating the first heating unit 5. This high degree of functional integration optimizes the structural design of the de-icing device and eliminates the need for separate mounting positions for the first heating unit 5 in other locations on the first body 1, thus contributing to the miniaturization of the first body 1. Similarly, the second bottom beam 23, in addition to its function of cooperating with the second extension arm 24 to form the second body 2, further integrates the function of accommodating the second heating unit 6. This high degree of functional integration optimizes the structural design of the de-icing device and eliminates the need for separate mounting positions for the second heating unit 6 in other locations on the second body 2, thus contributing to the miniaturization of the second body 2.

[0085] like Figure 1 , Figure 2As shown, the first clearance hole 131 is formed on the side wall of the first bottom beam 13 facing the first air outlet unit 3, and the second clearance hole 231 is formed on the side wall of the second bottom beam 23 facing the second air outlet unit. With this arrangement, the first clearance hole 131 and the second clearance hole 231 are respectively formed on the side walls of the first bottom beam 13 and the second bottom beam 23, so that the first transmission pipe 7 and the second transmission pipe 8 can extend horizontally to the first air outlet unit 3 and the second air outlet unit 4, thereby minimizing the occupation of the vertical space of the first body 1 and the second body 2, which helps to flatten the first body 1 and the second body 2, and can play a better adaptation role for some battery swapping vehicles with low chassis.

[0086] Preferably, such as Figure 1 , Figure 2 As shown, there are two first heating units 5. The two first heating units 5 are arranged at intervals along the length direction of the battery pack (i.e., the width direction of the first body 1), and each is connected to the first air outlet unit 3 through a corresponding first transmission pipe 7.

[0087] Preferably, there are two second heating units 6, which are spaced apart along the length of the battery pack (i.e., the width of the second body 2) and are each connected to the second air outlet unit 4 through a corresponding second transmission pipe 8.

[0088] Preferably, such as Figure 1 , Figure 2 As shown, there are two first heating units 5, which are spaced apart along the length of the battery pack (i.e., the width of the first body 1) and each is connected to the first air outlet unit 3 through a corresponding first transmission pipe 7. There are also two second heating units 6, which are spaced apart along the length of the battery pack (i.e., the width of the second body 2) and each is connected to the second air outlet unit 4 through a corresponding second transmission pipe 8. By setting the number of first heating units 5 and second heating units to two, and supplying air to the first air outlet unit 3 and the second air outlet unit 4 through two first transmission pipes 7 and two second transmission pipes 8 respectively, the heating efficiency of the first heating units 5 and the second air outlet unit 4 can be improved, increasing the amount of hot air delivered to them, thereby achieving rapid de-icing of the locking mechanism. Furthermore, it allows for more uniform air supply to the first air outlet unit 3 and the second air outlet unit 4, thus improving the uniformity of air supply to the locking mechanism.

[0089] Furthermore, such as Figure 1 , Figure 2 As shown, the first heating unit 5 also has a flue pipe 9, which is located on one side of the first transmission pipe 7 and connected to the first air outlet unit 3.

[0090] Furthermore, such as Figure 1 , Figure 2 As shown, the second heating unit 6 also has a flue pipe 9, which is located on one side of the second transmission pipe 8 and connected to the second air outlet unit 4.

[0091] Furthermore, such as Figure 1 , Figure 2 As shown, both the first heating unit 5 and the second heating unit 6 have exhaust pipes 9. The exhaust pipes 9 are respectively located on the first transmission pipe 7 and on one side of the first transmission pipe 7, connecting to the first air outlet unit 3, and on one side of the second transmission pipe 8, connecting to the second air outlet unit 4. The exhaust pipes 9 guide the exhaust of the smoke generated when the first heating unit 5 and the second heating unit 6 generate hot air, preventing the smoke from escaping and affecting the de-icing operators. Furthermore, since the smoke generated by the first heating unit 5 and the second heating unit 6 generates hot air at a high temperature, even higher than the hot air temperature, connecting the exhaust pipes 9 to the first air outlet unit 3 and the second air outlet unit 4 allows the smoke to move towards the locking mechanism under the influence of the hot air, thus assisting in the melting of ice. This achieves the recycling of high-temperature smoke and increases the de-icing efficiency of the de-icing device.

[0092] Preferably, the first heating unit 5 and the second heating unit 6 can be diesel heaters. Diesel heaters have a simple structure, strong adaptability, and good heating effect. However, when working, diesel heaters may produce high-temperature exhaust gas containing solid particles such as soot and carbon deposits. This high-temperature exhaust gas is transmitted to the first air outlet unit 3 and the second air outlet unit 4 through the exhaust pipe 9, and the high-temperature exhaust gas is used to assist in melting ice in the locking mechanism.

[0093] More preferably, the exhaust pipe 9 is equipped with a filter screen, which can filter out the smoke, oil, and solid particles generated when the diesel engine is working, and deliver high-temperature smoke only to the first and second air outlet units, thus avoiding the smoke, oil, and solid particles from adversely affecting the locking mechanism and battery pack structure.

[0094] Preferably, such as Figure 1 , Figure 2 As shown, the side walls of the first bottom beam 13 and the second bottom beam 23 are respectively provided with transmission through holes 130. The exhaust pipe 9 extends horizontally through the transmission through holes 130 and is connected to the first air outlet unit 3 and the second air outlet unit 4 respectively.

[0095] As another preferred example under this embodiment, such as Figure 3 , Figure 4 , Figure 5As shown, the two ends of the first air outlet unit 3 in the length direction of the battery pack (i.e., the width direction of the first body 1) do not extend beyond the first baffle 11, and the two ends of the second air outlet unit 4 in the length direction of the battery pack (i.e., the width direction of the second body 2) do not extend beyond the second baffle 21.

[0096] Figure 3 In this diagram, L1 refers to the length of the first baffle 11, L2 refers to the length of the first air outlet unit 3, L3 refers to the length of the second air outlet unit 4, and L4 refers to the length of the second baffle 21. L1 ≥ L2, L4 ≥ L3. The first air outlet unit 3 and the second air outlet unit 4 are configured such that their ends do not exceed the first baffle 11 and the second baffle 21 in the length direction of the battery pack. This allows the first baffle 11 and the second baffle 21 to act as windbreaks for the air outlets 110 of the first air outlet unit 3 and the second air outlet unit 4 in the width direction of the vehicle body. This reduces the air supply interference of the air outlets 110, such as the airflow moving laterally along the vehicle body, and effectively improves the stability of the hot air direction locking mechanism during its movement.

[0097] This application does not limit the location or structural form of the air outlet 110, which can be implemented in any of the following ways:

[0098] Implementation method one: such as Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, the top of the first air outlet unit 3 and the second air outlet unit 4 are both provided with air outlets 110; the locking mechanism 140 has two rows and is arranged on both sides of the battery pack along the length direction of the battery pack, and the air outlets 110 extend from one end of the air outlet unit to the other end along the length direction of the battery pack. By placing the air outlet 110 at the top of the first air outlet unit 3 and the second air outlet unit 4, the distance between the air outlet 110 and the locking mechanism can be shortened, reducing the movement time of hot air between the air outlet 110 and the locking mechanism. This helps to shorten the heat loss during the movement of hot air from the air outlet 110 toward the locking mechanism, thereby improving the de-icing efficiency of the de-icing device. In addition, setting the locking mechanism 140 in two rows allows the two rows of locking mechanisms 140 to be installed more securely on the battery pack. Setting the air outlet 110 to extend along the length of the battery pack allows the hot air ejected from the air storage chamber 10 to provide uniform air supply to the locking mechanisms located on the side of the battery pack along the length of the battery pack. This improves the uniformity of air supply to each locking mechanism by the de-icing device, thereby ensuring that the ice layer at each locking mechanism is heated evenly and the de-icing time is approximately equal.

[0099] Implementation Method Two: (e.g.) Figure 3 , Figure 4 , Figure 5As shown, both the first air outlet unit 3 and the second air outlet unit 4 have air outlets 110 at their tops; there are multiple locking mechanisms, which are set on the battery pack in preset positions, and multiple air outlets, each corresponding to a different locking mechanism. The arrangement of the locking mechanisms in this configuration is diverse and can be customized according to actual needs. For example, Chinese Publication No. CN106080159A discloses one such arrangement of locking mechanisms. When the locking mechanism is frozen by ice and snow in winter, the de-icing device of this embodiment can be used to blow hot air onto the locking mechanism to remove the ice and snow. By placing the air outlet 110 at the top of the first air outlet unit 3 and the second air outlet unit 4, the distance between the air outlet 110 and the locking mechanism can be shortened, reducing the movement time of hot air between the air outlet 110 and the locking mechanism. This helps to shorten the heat loss during the movement of hot air from the air outlet 110 toward the locking mechanism, thereby improving the de-icing efficiency of the de-icing device. Setting multiple air outlets 110 and aligning them with each locking mechanism makes the de-icing precision of the air outlet unit to the locking mechanism higher. Each air outlet 110 supplies air to the corresponding locking mechanism, improving the utilization efficiency of hot air while ensuring uniform air supply, thus increasing the de-icing efficiency of the de-icing device.

[0100] As a preferred embodiment of implementation methods one and two, such as Figure 4 , Figure 5 As shown, the first air outlet unit 3 and the second air outlet unit 4 both have hollow interiors to form an air storage cavity 10. The bottom or side of the air storage cavity 10 is connected to the first heating unit 5 or the second heating unit 6, and the air outlet 110 is located at the top of the air storage cavity 10.

[0101] Because the air outlet unit is equipped with an air storage chamber 10, during the process of the first heating unit 5 and the second heating unit 6 respectively supplying hot air to the first air outlet unit 3 and the second air outlet unit 4, the hot air will first gather in the air storage chamber 10. After the air storage chamber 10 is full of hot air, as the first heating unit 5 and the second heating unit 6 continue to inject hot air into the air storage chamber 10, the air pressure in the air storage chamber 10 continuously increases. Under the action of pressure, the hot air in the air storage chamber 10 is ejected from the air outlet 110, driving the hot air to move towards the locking mechanism. The power source is the continuously increasing air pressure inside the air storage chamber 10. Since the air outlet 110 is located at the top of the air storage chamber 10, the air pressure driving force that drives the hot air to move towards the air outlet 110 is from bottom to top. This allows the hot air to reach the locking mechanism located above the air outlet 110 under the action of the upward driving force. In other words, by setting up the air storage chamber 10, the requirements on the first heating unit 5 and the direction of hot air delivery of the heating unit are reduced. It plays a role in regulating the turbulent airflow and improving the movement accuracy of the hot air, thereby helping to improve the de-icing efficiency.

[0102] As a preferred example in this embodiment, such as Figure 4 , Figure 5 As shown, the air storage chamber 10 has a first top surface 101 and a second top surface 102 spaced apart. The gap between the first top surface 101 and the second top surface 102 forms an air outlet 110. Both the first top surface 101 and the second top surface 102 are inclined and gradually extend from top to bottom in a direction away from each other. In this embodiment, the first top surface 101 and the second top surface 102 are symmetrically arranged along the air outlet 110.

[0103] Because the hot air supplied to the air storage cavity 10 by the first heating unit 5 and the second heating unit 6 moves randomly within the air storage cavity 10 under the action of kinetic energy, and the mutual impact between the hot air causes the movement direction of the hot air to become more chaotic, by setting the first top surface 101 and the second top surface 102, the hot air in the air storage cavity 10 can be guided. Under the guidance of the first top surface 101 and the second top surface 102, the hot air gradually converges towards the direction close to the air outlet 110. During the convergence of the hot air towards the air outlet 110, its movement direction is continuously adjusted by the action of the first top surface 101 and the second top surface 102, so that the hot air can move towards the locking mechanism after reaching the air outlet 110, reducing the probability of the hot air escaping in all directions after being ejected from the air outlet 110 due to the deviation of the movement direction, thereby further improving the de-icing efficiency of the de-icing device.

[0104] As another preferred embodiment under implementation method one and implementation method two, such as Figure 4 , Figure 5 As shown, the top of the air outlet 110 is provided with two air expansion plates 120, which are respectively arranged on both sides of the air outlet 110 and gradually extend from bottom to top in a direction away from each other.

[0105] Because of the expansion plate 120, after the hot air is ejected from the outlet 110, part of the hot air continues to move vertically upwards, while part of the hot air tends to move obliquely due to changes in air pressure. This part of the hot air with the oblique movement tendency moves along the extension direction of the expansion plate 120 under the guidance of the expansion plate 120, which increases the working efficiency of the hot air and also helps to reduce the design requirements of the outlet 110 size. That is, when the diameter of the outlet 110 is small, the hot air can still achieve all-round coverage of the ice layer at the locking mechanism under the action of the expansion plate 120. In addition, when the ice layer above the outlet 110 melts, the melted water droplets will be affected by their own gravity. The water drips downwards, and the hot air at the air outlet 110 has high thermal energy, so it can instantly evaporate the water droplets into water vapor. The air diffuser 120 can collect the melted water on the side of the air outlet 110, so that the water droplets dripping on the air diffuser 120 move along the air diffuser 120 towards the air outlet 110 under their own gravity and are quickly evaporated into water vapor under the action of hot air. This reduces the probability that the melted water will drip onto the first air outlet unit 3, the second air outlet unit 4 or other components and interfere with the components of the de-icing device. Therefore, by setting the air diffuser 120, more of the ice layer removed by the de-icing device is released in the form of water vapor, reducing the pressure on the collection and treatment of melted water.
