Description

Technical Field

[0001] This application belongs to the field of new energy vehicles, and particularly relates to a split-type deicing device. Background Art

[0002] With the entry of electric vehicles into the market, the cruising range has become an important factor hindering their development. Learning from the way traditional vehicles achieve cruising range by refueling, for electric vehicles, charging a discharged battery pack or directly disassembling the discharged battery pack to replace it with a fully charged one has become a key research and development direction for increasing the cruising range of electric vehicles.

[0003] Limited by battery material technology and charging technology, it takes at least dozens of minutes to fully charge a new energy vehicle after it runs out of power. For some new energy freight vehicles with a larger battery pack capacity, more charging time is required, which greatly affects the driving experience of users. Especially for some commercial vehicle owners, waiting for charging means reducing their working time. The time required to replace the battery pack is much shorter than the charging duration of the battery pack. Therefore, more and more new energy vehicles use detachable battery packs for energy supply, solving the disadvantages of long charging time and inconvenient charging of fixed battery packs. Specifically, multiple locking mechanisms need to be installed on the bottom of the vehicle, and the installation or disassembly of the battery pack is achieved through the locking or unlocking of the locking mechanisms and the mating parts on the battery pack. Moreover, for this type of new energy vehicle, due to the large weight and volume of the battery pack, special battery swapping equipment is required to disassemble and install the battery pack. However, in cold weather in the north, especially after heavy snow or heavy rain, a thick layer of ice will cover the bottom of the vehicle chassis. The ice layer will also wrap the locking mechanism, affecting the unlocking of the locking mechanism, resulting in the battery pack being frozen to the bottom of the vehicle by the ice layer, making it difficult or even impossible to disassemble. This will greatly increase the battery swapping time of the vehicle and cause congestion in the battery swapping station.

[0004] Therefore, before replacing the battery pack, a deicing device needs to be used 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 body. When deicing the locking mechanism, if deicing the locking mechanisms on both sides of the battery pack separately, it will take a long time. The speed of deicing directly affects the duration required for the entire battery swapping process, and the battery swapping duration is the most critical factor determining the user's battery swapping experience. Therefore, how to design a deicing device that can quickly melt ice has become a technical problem that urgently needs to be solved in this technical field. Summary of the Utility Model

[0005] This application provides a split-type deicing device to solve the technical problems that in cold weather, the ice layer on the bottom of the battery swapping vehicle freezes the locking mechanism of the battery pack, making it difficult or even impossible to disassemble the battery pack, resulting in difficult battery swapping and low battery swapping efficiency.

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

[0007] A split ice removal device is used for ice removal of 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 replacement of the battery pack. The ice removal device includes a first body and a second body. A first air outlet unit and a first heating unit for delivering hot air to the first air outlet unit are provided on the first body. A second air outlet unit and a second heating unit for delivering hot air to the second air outlet unit are provided on the second body. The first air outlet unit and the second air outlet unit are respectively arranged corresponding to the locking mechanisms on the corresponding sides of the battery pack, and the first body and the second body can respectively move from both sides in the width direction of the battery swapping vehicle to the bottom of the vehicle body of the battery swapping vehicle so that the first air outlet unit and the second air outlet unit are respectively aligned with the corresponding locking mechanisms.

[0008] By adopting the above technical solution, when removing ice from the locking mechanism at the bottom of the battery swapping vehicle, the first body and the second body are respectively pushed into the bottom of the vehicle body from the sides of the battery swapping vehicle, so that the first air outlet unit and the second air outlet unit are respectively aligned with the corresponding locking mechanisms, and hot air is respectively delivered to the first air outlet unit and the second air outlet unit through the first heating unit and the second heating unit, thereby realizing simultaneous ice removal of the corresponding locking mechanisms, which helps to shorten the ice removal time of the battery swapping vehicle and improve the user experience; in addition, since the first body and the second body are respectively pushed into the bottom of the vehicle body from both sides of the battery swapping vehicle, the requirement of the ice removal device for the unilateral space of the vehicle body of the battery swapping vehicle is reduced. For some situations where the unilateral space of the battery swapping vehicle is compact due to the relatively wide vehicle body width or the small space of the battery swapping station, the ice removal device of this application can be well adapted, improving the adaptability to different sizes of charging stations and different volumes of vehicles; furthermore, since the first body and the second body are respectively pushed in from both sides of the vehicle body, the movement paths required for the first body and the second body to drive the first air outlet unit and the second air outlet unit to be respectively aligned with the locking mechanisms, and the movement paths for pulling out the first body and the second body from the bottom of the vehicle body after the ice removal work is completed are shortened, increasing the ice removal efficiency.

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

[0010] By adopting the above technical solution, when the first body and the second body move towards the bottom of the vehicle body, after the first body and / or the second body are positioned with respect to the body of the battery swapping vehicle, the operator can know that the first air outlet unit and / or the second air outlet unit have been aligned with the locking mechanism, without having to observe the alignment of the first air outlet unit and / or the second air outlet unit with the locking mechanism from below the vehicle body. This greatly reduces the difficulty of aligning the first air outlet unit and / or the second air outlet unit with the locking mechanism, thereby significantly reducing the preparation time required for the preparation work before the deicing operation starts. At the same time, it avoids the possibility of misalignment between the first air outlet unit and / or the second air outlet unit and the locking mechanism caused by difficult observation or limited observation position of the operator, improves the deicing accuracy of the deicing device for the locking mechanism, and further reduces the ice melting time.

[0011] One side of the first body that does not extend into the bottom of the vehicle body of the battery swapping vehicle has a first baffle, and one side of the second body that does not extend into the bottom of the vehicle body of the battery swapping vehicle has a second baffle. A first connecting member is provided on the side of the first body away from the first baffle, and a second connecting member adapted to the first connecting member is provided on the side of the second body away from the second baffle. After the first body and the second body are respectively pushed into the bottom of the vehicle body of the battery swapping vehicle, the first baffle and the second baffle respectively abut against the corresponding sides of the vehicle body of the battery swapping vehicle, and the first connecting member and the second connecting member are connected to each other to lock the relative positions of the first body and the second body, thereby realizing the alignment of the first air outlet unit and the second air outlet unit with the corresponding locking mechanisms respectively.

[0012] By adopting the above technical solution, by providing the first baffle and the second baffle, on the one hand, the first baffle and the second baffle respectively play a role in cooperating 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 are in contact with 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, so that the airflow flowing from the side of the vehicle body to the bottom of the vehicle body can be blocked, the influence of the airflow on the hot air ejected by the first air outlet unit and the second air outlet unit can be reduced, the heating stability of the first air outlet unit and the second air outlet unit respectively supplying heat to the locking mechanism can be improved, and at the same time, it helps to reduce the diffusion of the heat at 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 providing the first connecting member and the second connecting member, when the first body and the second body are respectively pushed in place, at this time, the first baffle and the second baffle must be in complete contact with the side of the vehicle body respectively to realize the connection of the first connecting member and the second connecting member, so as to ensure that the extending directions of the first air outlet unit and the second air outlet unit are consistent with the extending direction of the locking mechanism, that is, it avoids the occurrence of the angular deviation phenomenon of the alignment between the first air outlet unit and / or the second air outlet unit and the locking mechanism caused by the partial contact with the vehicle body due to the deviation of the moving direction of the first body and / or the second body, and provides further guarantee for the de-icing accuracy of the de-icing device.

[0013] A first flexible pad is provided on one side of the first baffle facing the first connecting member, and / or a second flexible pad is provided on one side of the second baffle facing the second connecting member.

[0014] By adopting the above technical solution, when the first body and the second body move to the bottom of the body of the battery swapping vehicle, since the first baffle and the second baffle are respectively in contact with the side of the vehicle body, by providing the first flexible pad and the second flexible pad, the impact force when the first baffle and the second baffle are in contact with the body of the battery swapping vehicle can be reduced, so as to realize the relatively gentle contact between the first baffle and the second baffle and the body of the battery swapping vehicle respectively, and reduce the probability of the first baffle, the second baffle or the vehicle body being impacted and deformed due to the too fast moving speed of the first body and the second body.

[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 connecting member 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 connecting member 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 solutions, the two first extension arms and the two second extension arms respectively provide installation and bearing functions for the first air outlet unit and the second air outlet unit. The two first extension arms jointly bear 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 deflecting under the impact of hot air during operation. Similarly, the second air outlet unit is the same; in addition, setting the first body and the second body as U-shaped frames can make the centers of gravity of the first body and the second body more stable, improve their stability during movement, and prevent the first body and the second body from deviating during movement due to the offset of the center of gravity; and the first connecting member and the second connecting member are respectively disposed at the ends of the first extension arm and the second extension arm. When docking the first body and the second body, 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 avoidance hole. 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 avoidance hole; and / or, the second bottom beam is provided with a second avoidance hole. 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 avoidance hole.

[0018] By adopting the above technical solutions, on the basis of the function of the first bottom beam cooperating with the first extension arm to form the first body, the function of accommodating the first heating unit is further integrated, with a high degree of function integration, optimizing the structural design of the de-icing device. At the same time, it saves the installation position for separately installing the first heating unit at other positions of the first body, contributing to the miniaturization of the first body; similarly, on the basis of the function of the second bottom beam cooperating with the second extension arm to form the second body, the function of accommodating the second heating unit is further integrated, with a high degree of function integration, optimizing the structural design of the de-icing device. At the same time, it saves the installation position for separately installing the second heating unit at other positions of the second body, contributing to the miniaturization of the second body.

[0019] There are two of the first heating units, and the two first heating units are arranged at intervals along the length direction of the battery pack, and each is communicated with the first air outlet unit through the corresponding first transmission pipe; and / or, there are two of the second heating units, and the two second heating units are arranged at intervals along the length direction of the battery pack, and each is communicated with the second air outlet unit through the 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 the first air outlet unit and the second air outlet unit are supplied with air through the two first transmission pipes and the two second transmission pipes respectively. On the one hand, it can improve the heating efficiency of the first heating unit and the second air outlet unit, increase the hot air delivery volume to the first air outlet unit and the second air outlet unit, so as to realize the rapid deicing of the locking mechanism; on the other hand, it can realize the relatively uniform air supply to the first air outlet unit and the second air outlet unit, and then improve the uniformity of the air supply of the first air outlet unit and the second air outlet unit to the locking mechanism.

[0021] The first heating unit further has an exhaust pipe, and the exhaust pipe is arranged on one side of the first transmission pipe and communicated with the first air outlet unit; and / or, the second heating unit further has an exhaust pipe, and the exhaust pipe is arranged on one side of the second transmission pipe and communicated with the second air outlet unit.

[0022] By adopting the above technical solution, the setting of the exhaust pipe plays a role in guiding and discharging the smoke generated when the first heating unit and the second heating unit manufacture hot air, avoiding the smoke from escaping everywhere and affecting the deicing operator; in addition, since the smoke generated when the first heating unit and the second heating unit manufacture hot air has a high temperature, even higher than the temperature of the hot air, therefore, the exhaust pipe is set to be communicated with the first air outlet unit and / or the second air outlet unit, and the smoke moves towards the locking mechanism under the entrainment of the hot air and plays an auxiliary ice melting effect, realizing the recycling of the high-temperature smoke and increasing the deicing efficiency of the deicing device.

[0023] Both ends of the first air outlet unit in the length direction of the battery pack do not exceed the first baffle, and both ends of the second air outlet unit in the length direction of the battery pack do not exceed the second baffle.

[0024] By adopting the above technical solution, the first air outlet unit and the second air outlet unit are set so that both 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 play a role in blocking the wind in the vehicle body width direction for the first air outlet unit and the second air outlet unit, reducing the air supply interference of the airflow moving in the vehicle body transverse direction to the first air outlet unit and the second air outlet unit, and effectively improving the stability of the hot air moving towards the locking mechanism;

[0025] The first air outlet unit and the second air outlet unit are both provided with air outlets at the top; the locking mechanism has two rows, which are arranged on both sides of the battery pack along the length direction of the battery pack, and the air outlet extends from one end of the air outlet unit to the other end along the length direction of the battery pack; 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 the respective locking mechanisms.

[0026] By adopting the above technical solution, the air outlet is arranged at the top of the first air outlet unit and the second air outlet unit, which can shorten the distance between the air outlet and the locking mechanism, and reduce the movement time of the hot air between the air outlet and the locking mechanism, thereby helping to shorten the heat loss in the process of hot air being ejected from the air outlet and moving toward the locking mechanism, and improving the ice melting efficiency of the de-icing device; in addition, the locking mechanism is arranged in two rows, which can make the two rows of locking mechanisms more stable for the installation of the battery pack, and the air outlet is arranged to extend along the length direction of the battery pack, so that the battery pack can be locked by the battery pack. The hot air ejected from the wind cavity can evenly supply air to the locking mechanisms located on the sides of the battery pack in the length direction, 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 providing multiple air outlets and aligning them with each locking mechanism allows the air outlet unit to have higher de-icing accuracy for the locking mechanism, and each air outlet supplies air to the corresponding locking mechanism, thereby improving the utilization efficiency of the hot air while ensuring uniform air supply, thereby increasing the de-icing efficiency of the de-icing device.

[0027] The first air outlet unit and the second air outlet unit both have a hollow interior 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 scheme, since the air outlet unit is provided with an air storage chamber, therefore, in the process that the first heating unit and the second heating unit respectively convey hot air to the first air outlet unit and the second air outlet unit, the hot air will first gather in the air storage chamber, and when the air storage chamber is full of hot air, since the first heating unit and the second heating unit continue to infuse the air storage chamber with hot air, the air pressure in the air storage chamber continues to increase, and the hot air in the air storage chamber is ejected from the air outlet under the action of pressure, and the power source for driving the hot air to move toward the locking mechanism is the continuously increasing air pressure in the air storage chamber, and since the air outlet is arranged at the top of the air storage chamber, the air pressure driving force for driving the hot air to move toward 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 driving force from bottom to top; that is, by providing the air storage chamber, the requirements for the hot air conveying direction of the first heating unit and the heating unit are reduced, the airflow with disordered movement direction is regulated, the movement accuracy of the hot air is improved, and thus it is helpful to improve the deicing efficiency.

[0029] The air storage cavity has a first top surface and a second top surface which are spaced apart, and a 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 away from each other in the downward direction.

[0030] By adopting the above technical solution, since the hot air delivered 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, it can play a guiding role in the hot air in the air storage cavity. Under the guiding action of the first top surface and the second top surface, the hot air gradually converges along the direction close to the air outlet, and during the convergence process of the hot air towards the air outlet, its movement direction is continuously adjusted under the action of the first top surface and the second top surface, so that the hot air can move towards the locking mechanism after moving to the air outlet, reducing the probability that the hot air escapes in all 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.

[0031] Two wind spreading plates are provided at the top of the air outlet, and the two wind spreading plates are correspondingly arranged on both sides of the air outlet and extend away from each other gradually in the upward direction.

[0032] By adopting the above technical solution, due to the setting of the wind spreading plates, 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 under the action of air pressure change. This part of the hot air with the tendency to move obliquely moves along the extension direction of the wind spreading plates under the guiding action of the wind spreading plates, increasing the working efficiency of the hot air and also helping to reduce the requirements for the size design of the air outlet, that is, when the diameter of the air outlet is small, the hot air can still achieve full coverage of the ice layer at the locking mechanism under the action of the wind spreading plates; in addition, when the ice layer above the air outlet is melted, the melted water droplets will drip downward under the action of their own gravity, and the hot air at the air outlet has high heat energy, so it can instantaneously evaporate the water droplets into water vapor, and the wind spreading plates can collect the ice-melt water on the side of the air outlet, making the water droplets dripping on the wind spreading plates move towards the air outlet along the wind spreading plates under the action of their own gravity and quickly evaporate into water vapor under the action of the hot air, reducing the probability that the ice-melt water droplets drip onto the first air outlet unit, the second air outlet unit or other components to interfere with the components of the de-icing device; therefore, by setting the wind spreading plates, more of the ice layer removed by the de-icing device is released in the form of water vapor, reducing the pressure of collecting and treating the ice-melt water.

[0033] Due to adopting the above technical solution, the beneficial effects obtained by this application are:

[0034] When de-icing the locking mechanism at the bottom of the battery swapping vehicle, the first body and the second body are respectively pushed into the bottom of the vehicle body from the side of the battery swapping vehicle, so that the first air outlet unit and the second air outlet unit are respectively aligned with two rows of locking mechanisms, and hot air is respectively conveyed to the first air outlet unit and the second air outlet unit through the first heating unit and the second heating unit, thereby realizing simultaneous de-icing of the two rows of locking mechanisms, which helps to shorten the de-icing time of the battery swapping vehicle and improve the user experience. In addition, since the first body and the second body are respectively pushed into the bottom of the vehicle body from both sides of the vehicle body of the battery swapping vehicle, the requirement of the de-icing device for the unilateral space of the vehicle body of the battery swapping vehicle is reduced. For the situation where the unilateral space of the battery swapping vehicle is compact due to the relatively wide body width of the vehicle or the small space of the battery swapping station, the de-icing device of the present application can be well adapted, improving the adaptation degree to charging stations of different sizes and vehicles of different volumes. Moreover, since the first body and the second body are respectively pushed in from both sides of the vehicle body, the movement paths required for the first body and the second body to drive the first air outlet unit and the second air outlet unit to be aligned with the locking mechanism respectively, and the movement paths for pulling out the first body and the second body from the bottom of the vehicle body after the de-icing work is completed are shortened, increasing the de-icing efficiency.

[0064] As Figure 1 , Figure 2 , Figure 6 As shown in

[0065] Figure 6 The direction indicated by the arrow Y is the longitudinal direction of the body of the battery swapping vehicle 150, and the direction indicated by the arrow X is the moving direction of the deicing device into the bottom of the body of the battery swapping vehicle 220. The first body 1 and the second body 2 enter the bottom of the battery swapping vehicle 220 along both sides of the body respectively. When deicing the locking mechanism at the bottom of the battery swapping vehicle, the first body 1 and the second body 2 are respectively pushed into the bottom of the body from the side of the battery swapping vehicle, so that the first air outlet unit 3 and the second air outlet unit 4 are respectively aligned with the two rows of locking mechanisms, and the first heating unit 5 and the second heating unit 6 respectively convey hot air to the first air outlet unit 3 and the second air outlet unit 4, thereby realizing simultaneous deicing of the two rows of locking mechanisms, which helps to shorten the deicing time of the battery swapping vehicle and improve the user experience; in addition, since the first body 1 and the second body 2 are respectively pushed into the bottom of the body from both sides of the body of the battery swapping vehicle, the requirement of the deicing device for the unilateral space of the body of the battery swapping vehicle is reduced. For the situation where the unilateral space of the battery swapping vehicle is compact due to the relatively wide body width or the small space of the battery swapping station, the deicing device of the present application can be well adapted, 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 respectively pushed in from both sides of the body, the movement paths required for the first body 1 and the second body 2 to drive the first air outlet unit 3 and the second air outlet unit 4 to be respectively aligned with the locking mechanism, and the movement paths for pulling out the first body 1 and the second body 2 from the bottom of the body after the deicing work is completed are shortened, increasing the deicing efficiency.

[0066] Preferably, moving wheels are provided at the bottoms of the first body 1 and the second body 2, and handrails are further provided on the sides of the first body 1 and the second body 2 facing away from each other. The first body 1 and the second body 2 are respectively pushed into the bottom of the body from both sides of the body of the battery swapping vehicle through the handrails.

[0067] The present application does not limit the positional relationship between the first body 1, the second body 2 and the body, and any one of the following implementation manners can be adopted:

[0068] Embodiment 1: The first body 1 can be positioned corresponding to the corresponding side of the body of the battery swapping vehicle to realize the alignment of the first air outlet unit 3 with the corresponding locking mechanism. When the first body 1 moves towards the bottom of the body, when the first body 1 is positioned with the body of the battery swapping vehicle, the operator can know that the first air outlet unit 3 has been aligned with the locking mechanism, without having to observe the alignment situation between the first air outlet unit 3 and the locking mechanism from below the body, greatly reducing the alignment difficulty between the first air outlet unit 3 and the locking mechanism, thereby significantly reducing the preparation time required for the preparation work before the deicing work starts; at the same time, it avoids the possibility of misalignment between the first air outlet unit 3 and the locking mechanism caused by difficult observation or limited observation position of the operator, improving the deicing accuracy of the deicing device for the locking mechanism and further reducing the ice melting time.

[0069] Embodiment 2: The second body 2 can be positioned corresponding to the corresponding side of the body of the battery swapping vehicle to align the second air outlet unit 4 with the corresponding locking mechanism. When the second body 2 moves towards the bottom of the body, after the second body 2 is positioned with the body of the battery swapping vehicle, the operator can know that the second air outlet unit 4 has been aligned with the locking mechanism, without having to observe the alignment situation of the second air outlet unit 4 and the locking mechanism from below the body upwards. This greatly reduces the alignment difficulty between the second air outlet unit 4 and the locking mechanism, thereby significantly reducing the preparation time required for the preparation work before the defrosting work starts; at the same time, it avoids the possibility of deviation between the second air outlet unit 4 and the locking mechanism caused by difficult observation or limited observation position of the operator, improves the defrosting accuracy of the defrosting device for the locking mechanism, and further reduces the ice melting time.

[0070] Embodiment 3: The first body and the second body 2 can be respectively positioned corresponding to the corresponding side of the body of the battery swapping vehicle to align the first air outlet unit 3 and the second air outlet unit 4 with the corresponding locking mechanisms. When the first body 1 and the second body 2 move towards the bottom of the body, after the first body 1 and the second body 2 are positioned with the body of the battery swapping vehicle, the operator can know that the first air outlet unit 3 and the second air outlet unit 4 have been aligned with the locking mechanisms, without having to observe the alignment situations of the first air outlet unit 3 and the second air outlet unit 4 with the locking mechanisms respectively from below the body upwards. This greatly reduces the alignment difficulty between the first air outlet unit 3 and the second air outlet unit 4 and the locking mechanisms, thereby significantly reducing the preparation time required for the preparation work before the defrosting work starts; at the same time, it avoids the possibility of deviation between the first air outlet unit 3 and the second air outlet unit 4 and the locking mechanisms respectively caused by difficult observation or limited observation position of the operator, improves the defrosting accuracy of the defrosting device for the locking mechanisms, and further reduces the ice melting time.

[0071] As a preferred embodiment under Embodiments 1 to 3, as Figure 1 、 Figure 2 shown, one side of the first body 1 that does not extend into the bottom of the body of the battery swapping vehicle has a first baffle 11, one side of the second body 2 that does not extend into the bottom of the body of the battery swapping vehicle has a second baffle 21, a first connecting member 12 is provided on the side of the first body 1 away from the first baffle 11, and a second connecting member 22 adapted to the first connecting member 12 is provided on the side of the second body 2 away from the second baffle 21. After the first body 1 and the second body 2 are respectively pushed into the bottom of the body of the battery swapping vehicle, the first baffle 11 and the second baffle 21 respectively abut against the corresponding sides of the body of the battery swapping vehicle, and the first connecting member 12 and the second connecting member 22 are connected to each other to lock the relative positions 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 mechanisms respectively.

[0072] By setting the first baffle 11 and the second baffle 21, on the one hand, they respectively play a role in cooperating with the vehicle body to position the first air outlet unit 3 and the second air outlet unit 4 for the first body 1 and the second body 2. On the other hand, the first baffle 11 and the second baffle 21 can also block the airflow flowing from the side of the vehicle body to the bottom of the vehicle body, reduce the influence of the airflow on the hot air ejected by the first air outlet unit 3 and the second air outlet unit 4, improve the heating stability of the first air outlet unit 3 and the second air outlet unit 4 to the locking mechanism respectively, and at the same time help to reduce the diffusion of the heat at the bottom of the vehicle body to the side of the vehicle body, which is helpful to further improve the deicing speed of the deicing device; in addition, by setting the first connecting piece 12 and the second connecting piece 22, when the first body 1 and the second body 2 are respectively pushed in place, at this time, the first baffle 11 and the second baffle 21 need to be completely attached to the side of the vehicle body respectively to realize the connection of the first connecting piece 12 and the second connecting piece 22, so as to ensure that the extending directions of the first air outlet unit 3 and the second air outlet unit 4 are consistent with the extending direction of the locking mechanism, that is, to avoid the occurrence of the angular deviation of the alignment between the first air outlet unit 3 and the second air outlet unit 4 and the locking mechanism caused by the partial contact with the vehicle body due to the deviation of the moving directions of the first body 1 and the second body 2, which provides further guarantee for the deicing accuracy of the deicing device.

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

[0074] In this embodiment, the structural forms of the first baffle 11 and the second baffle 21 are not limited. In a preferred example, a first flexible pad is provided on the side of the first baffle 11 facing the first connecting piece 12; in another preferred example, a second flexible pad is provided on the side of the second baffle 21 facing the second connecting piece 22; in still another preferred example, a first flexible pad is provided on the side of the first baffle 11 facing the first connecting piece 12, and a second flexible pad is provided on the side of the second baffle 21 facing the second connecting piece 22.

[0075] When the first body 1 and the second body 2 move to the bottom of the body of the battery swapping vehicle, since the first baffle 11 and the second baffle 21 are respectively in contact with the side of the vehicle body, by setting the first flexible pad and the second flexible pad, the impact force when the first baffle 11 and the second baffle 21 are in contact with the body of the battery swapping vehicle can be reduced, so as to realize the relatively gentle contact between the first baffle 11 and the second baffle 21 and the body of the battery swapping vehicle respectively, and reduce the probability of the first baffle 11, the second baffle 21 or the vehicle body being impacted and deformed due to the too fast moving speed of the first body 1 and the second body 2.

[0076] In this embodiment, the structural forms of the first body and the second body are not limited, and any of the following examples can be adopted:

[0077] Example 1: As Figures 1 to 3 shown, the first body 1 is a U-shaped frame, including a first bottom beam 13 and two first extension arms 14 arranged 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 connecting member 12 is disposed at the end of the first extension arm 14 away from the first bottom beam 13. The first air outlet unit 3 is connected between the two first extension arms 14.

[0078] Example 2: As Figures 1 to 3 shown, the second body 2 is a U-shaped frame, including a second bottom beam 23 and two second extension arms 24 arranged 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 connecting member 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: As Figures 1 to 3 shown, the first body 1 is a U-shaped frame, including a first bottom beam 13 and two first extension arms 14 arranged 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 connecting member 12 is disposed at the end of the first extension arm 14 away from the first bottom beam 13. The 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 arranged 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 connecting member 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. The two first extension arms 14 and the two second extension arms 24 respectively provide installation and bearing functions for the first air outlet unit 3 and the second air outlet unit 4. The two first extension arms 14 jointly bear 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 deflecting under the impact of hot air during operation. Similarly, the second air outlet unit 4 is the same; in addition, setting the first body 1 and the second body 2 as U-shaped frames can make the centers 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 deviating in movement due to the offset of the center of gravity during movement; and the first connecting member 12 and the second connecting member 22 are respectively disposed at the ends of the first extension arm 14 and the second extension arm 24. When docking the first body 1 and the second body 2, 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 in parallel with the first air outlet unit 3, and the distance between the two corresponds to the distance between the side of the vehicle body and the locking mechanism on the corresponding side; the second bottom beam 23 is arranged in parallel with the second air outlet unit 4, and the distance between the two also corresponds to the distance between the side of the vehicle body and the locking mechanism on the corresponding side. Such an arrangement enables the first air outlet unit 3 and the second air outlet unit 4 to correspond to the locking mechanism on the corresponding side when the first baffle 11 and the second baffle 21 abut against the side of the vehicle body. Further, 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 positions of the first air outlet unit 3 and the second air outlet unit 4 relative to the locking mechanism on the corresponding side. Preferably, as Figure 1 , Figure 2 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, so that the extending directions of the first extension arm 14 and the second extension arm 24 are on the same horizontal line, which helps to reduce the connection difficulty between the first connecting member 12 and the second connecting member 22, thereby improving the alignment stability between the first body 1 and the second body 2.

[0081] The above example does not limit the structural forms of the first bottom beam and the second bottom beam, and any one of the following preferred methods can be adopted:

[0082] Method 1: As Figure 1 , Figure 2 shown, the first bottom beam 13 is provided with a first avoidance 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 avoidance hole 131.

[0083] Method 2: As Figure 1 , Figure 2 shown, the second bottom beam 23 is provided with a second avoidance 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 avoidance hole 231.

[0084] Method 3: As Figure 1 , Figure 2As shown, the first bottom beam 13 is provided with a first avoidance 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 avoidance hole 131. The second bottom beam 23 is provided with a second avoidance 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 avoidance hole 231. On the basis of the function of the first bottom beam 13 cooperating with the first extension arm 14 to form the first body 1, the function of accommodating the first heating unit 5 is further integrated, with a high degree of function integration, optimizing the structural design of the deicing device. At the same time, it saves the installation position for loading the first heating unit 5 separately at other positions of the first body 1, contributing to the miniaturization of the first body 1. Similarly, on the basis of the function of the second bottom beam 23 cooperating with the second extension arm 24 to form the second body 2, the function of accommodating the second heating unit 6 is further integrated, with a high degree of function integration, optimizing the structural design of the deicing device. At the same time, it saves the installation position for loading the second heating unit 6 separately at other positions of the second body 2, contributing to the miniaturization of the second body 2.

[0085] As Figure 1 、 Figure 2 shown, the first avoidance hole 131 is opened on the side wall of the first bottom beam 13 facing the first air outlet unit 3, and the second avoidance hole 231 is opened on the side wall of the second bottom beam 23 facing the second air unit. With such a setting, the first avoidance hole 131 and the second avoidance hole 231 are respectively opened on the side walls of the first bottom beam 13 and the second bottom beam 23, enabling the first transmission pipe 7 and the second transmission pipe 8 to 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, contributing to the flattening of the first body 1 and the second body 2, and achieving a better adaptation effect for some battery swapping vehicles with a lower chassis.

[0086] Preferably, as Figure 1 、 Figure 2 shown, there are two first heating units 5, and 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 communicated with the first air outlet unit 3 through the corresponding first transmission pipe 7.

[0087] Preferably, there are two second heating units 6, and the two second heating units 6 are arranged at intervals along the length direction of the battery pack (i.e., the width direction of the second body 2), and each is communicated with the second air outlet unit 4 through the corresponding second transmission pipe 8.

[0088] Preferably, as Figure 1 、 Figure 2As shown in the figure, there are two first heating units 5, and 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 communicated with the first air outlet unit 3 through a corresponding first transmission pipe 7; there are two second heating units 6, and the two second heating units 6 are arranged at intervals along the length direction of the battery pack (i.e., the width direction of the second body 2), and each is communicated with the second air outlet unit 4 through a corresponding second transmission pipe 8. Setting the number of the first heating units 5 and the second units to two, and supplying air to the first air outlet unit 3 and the second air outlet unit 4 through the two first transmission pipes 7 and the two second transmission pipes 8 respectively can, on the one hand, improve the heating efficiency of the first heating unit 5 and the second air outlet unit 4, increase the hot air delivery volume to the first air outlet unit 3 and the second air outlet unit 4, so as to quickly de-ice the locking mechanism; on the other hand, it can supply air to the first air outlet unit 3 and the second air outlet unit 4 more evenly, and then improve the air supply uniformity of the first air outlet unit 3 and the second air outlet unit 4 to the locking mechanism.

[0089] Further, as Figure 1 , Figure 2 shown, the first heating unit 5 further has an exhaust pipe 9, and the exhaust pipe 9 is arranged on one side of the first transmission pipe 7 and communicated with the first air outlet unit 3.

[0090] Further, as Figure 1 , Figure 2 shown, the second heating unit 6 further has an exhaust pipe 9, and the exhaust pipe 9 is arranged on one side of the second transmission pipe 8 and communicated with the second air outlet unit 4.

[0091] Even further, as Figure 1 , Figure 2 shown, both the first heating unit 5 and the second heating unit 6 have an exhaust pipe 9. The exhaust pipe 9 is respectively arranged on one side of the first transmission pipe 7 and communicated with the first air outlet unit 3, and on one side of the second transmission pipe 8 and communicated with the second air outlet unit 4. The setting of the exhaust pipe 9 functions to guide the discharge of the smoke generated when the first heating unit 5 and the second heating unit 6 produce hot air, avoiding the smoke from escaping everywhere and affecting the de-icing operator; in addition, since the temperature of the smoke generated when the first heating unit 5 and the second heating unit 6 produce hot air is relatively high, even higher than the temperature of the hot air, therefore, the exhaust pipe 9 is set to be communicated with the first air outlet unit 3 and the second air outlet unit 4. The smoke moves towards the locking mechanism direction under the entrainment of the hot air and has an auxiliary ice melting effect, realizing the recycling of the high-temperature smoke and increasing the de-icing efficiency of the de-icing device.

[0092] Preferably, the first heating unit 5 and the second heating unit 6 can be a diesel heater. The diesel heater has a simple structure, strong adaptability, and good heating effect. However, when the diesel heater is working, it may produce high-temperature exhaust gas containing solid particles such as soot and carbon deposits. This part of the 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 de-icing the locking mechanism.

[0093] More preferably, a filter screen is provided in the exhaust pipe 9. The filter screen can filter the soot, solid particles, etc. generated when the diesel heater is working, and only convey high-temperature smoke to the first air outlet unit and the second air outlet unit, avoiding the adverse effects of soot, solid particles, etc. on the locking mechanism and the battery pack structure.

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

[0095] As another preferred example in this embodiment, as Figure 3 、 Figure 4 、 Figure 5 shown, both 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 both 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 Figure 3 , 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; setting the first air outlet unit 3 and the second air outlet unit 4 so that both ends in the length direction of the battery pack do not extend beyond the first baffle 11 and the second baffle 21 enables the first baffle 11 and the second baffle 21 to play a role in blocking the air outlet 110 of the first air outlet unit 3 and the second air outlet unit 4 in the vehicle body width direction, reducing the air supply interference of the air flow moving horizontally along the vehicle body to the air outlet 110, and effectively improving the stability of the hot air moving towards the locking mechanism.

[0097] The present application does not limit the position and structural form of the air outlet 110, and it can adopt any one of the following implementation manners:

[0098] Implementation manner 1: As Figure 3 、 Figure 4 、 Figure 5 、 Figure 7As shown in the figure, air outlets 110 are provided at the tops of both the first air outlet unit 3 and the second air outlet unit 4; the locking mechanism 140 has two columns, which are 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 to the other end of the air outlet unit along the length direction of the battery pack. By arranging the air outlets 110 at the tops of the first air outlet unit 3 and the second air outlet unit 4, the distance between the air outlets 110 and the locking mechanism can be shortened, and the movement time of the hot air between the air outlets 110 and the locking mechanism can be reduced, thereby helping to shorten the heat loss during the movement of the hot air ejected from the air outlets 110 and towards the locking mechanism, and improving the ice melting efficiency of the de-icing device; in addition, by setting the locking mechanism 140 into two columns, the two columns of locking mechanisms 140 can provide a more stable installation for the battery pack. By arranging the air outlets 110 to extend along the length direction of the battery pack, the hot air ejected from the air storage cavity 10 can evenly supply air to the locking mechanisms located on the side parts in the length direction of the battery pack, improving the air supply uniformity of the de-icing device to each locking mechanism, so as to ensure that the ice layers at each locking mechanism are evenly heated and the ice melting times are approximately equal.

[0099] Embodiment 2: As Figure 3 , Figure 4 , Figure 5 shown in the figure, air outlets 110 are provided at the tops of both the first air outlet unit 3 and the second air outlet unit 4; there are multiple locking mechanisms, which are arranged on the battery pack at preset positions, and there are multiple air outlets, and the positions of the multiple air outlets correspond to those of each locking mechanism. The arrangement of the locking mechanisms in this form is diversified and can be set according to actual needs. For example, one arrangement method of the locking mechanism is disclosed in Chinese Patent Publication No. CN106080159A. 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 to the locking mechanism to remove ice and snow. By arranging the air outlets 110 at the tops of the first air outlet unit 3 and the second air outlet unit 4, the distance between the air outlets 110 and the locking mechanism can be shortened, and the movement time of the hot air between the air outlets 110 and the locking mechanism can be reduced, thereby helping to shorten the heat loss during the movement of the hot air ejected from the air outlets 110 and towards the locking mechanism, and improving the ice melting efficiency of the de-icing device; by arranging the air outlets 110 in multiple numbers and setting them in correspondence with each locking mechanism, the de-icing accuracy of the air outlet unit for the locking mechanism is higher. Each air outlet 110 supplies air to the corresponding locking mechanism, improving the utilization efficiency of the hot air on the premise of ensuring uniform air supply and increasing the de-icing efficiency of the de-icing device.

[0100] As a preferred embodiment under Embodiment 1 and Embodiment 2, as Figure 4 , Figure 5As shown, both the first air outlet unit 3 and the second air outlet unit 4 have a hollow interior to form an air storage cavity 10. The bottom or side of the air storage cavity 10 communicates with 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] Since the air outlet unit is provided with the air storage cavity 10, during the process of the first heating unit 5 and the second heating unit 6 respectively delivering hot air to the first air outlet unit 3 and the second air outlet unit 4, the hot air will first converge in the air storage cavity 10. After the air storage cavity 10 is filled with hot air, due to the continuous hot air perfusion into the air storage cavity 10 by the first heating unit 5 and the second heating unit 6, the air pressure in the air storage cavity 10 continuously increases. Under the action of pressure, the hot air in the air storage cavity 10 is ejected from the air outlet 110. The power source for driving the hot air to the locking mechanism is the continuously increasing air pressure in the air storage cavity 10. Since the air outlet 110 is arranged at the top of the air storage cavity 10, the air pressure driving force for driving the hot air to the air outlet 110 is from bottom to top, so that the hot air can reach the locking mechanism located above the air outlet 110 under the driving force from bottom to top; that is, by setting the air storage cavity 10, the requirements for the hot air delivery direction of the first heating unit 5 and the heating unit are reduced, the airflow with disordered movement directions is regulated, the movement accuracy of the hot air is improved, and thus the de-icing efficiency is helped to be improved.

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

[0103] Since the hot air delivered to the air storage cavity 10 by the first heating unit 5 and the second heating unit 6 moves randomly in the air storage cavity 10 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 101 and the second top surface 102, the hot air in the air storage cavity 10 can be guided. Under the guiding action of the first top surface 101 and the second top surface 102, the hot air gradually converges in the direction close to the air outlet 110, and its movement direction is continuously adjusted under the action of the first top surface 101 and the second top surface 102 during the convergence process of the hot air towards the air outlet 110, so that the hot air can move towards the locking mechanism direction 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, and thus further improving the de-icing efficiency of the de-icing device.

[0104] As another preferred embodiment under Embodiment 1 and Embodiment 2, as Figure 4 , Figure 5 shown, two wind deflectors 120 are provided at the top of the air outlet 110, and the two wind deflectors 120 are correspondingly arranged on both sides of the air outlet 110 and gradually extend away from each other from bottom to top.

[0105] Due to the arrangement of the wind deflectors 120, after the hot air is ejected from the air outlet 110, 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 under the action of air pressure change. This part of the hot air with a tendency to move obliquely moves along the extension direction of the wind deflector 120 under the guiding action of the wind deflector 120, which not only increases the working efficiency of the hot air but also helps to reduce the requirements for the size design of the air outlet 110. That is, when the diameter of the air outlet 110 is small, the hot air can still achieve full coverage of the ice layer at the locking mechanism under the action of the wind deflector 120; in addition, when the ice layer above the air outlet 110 is melted, the melted water droplets will drip downward under the action of their own gravity, and the hot air at the air outlet 110 has a high heat energy, so it can instantaneously evaporate the water droplets into water vapor. The wind deflector 120 can collect the ice-melt water on the side of the air outlet 110, so that the water droplets dripping on the wind deflector 120 move along the wind deflector 120 towards the air outlet 110 under the action of their own gravity and are quickly evaporated into water vapor under the action of the hot air, reducing the probability that the ice-melt water droplets fall 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 wind deflector 120, more of the ice layer removed by the de-icing device is released in the form of water vapor, reducing the pressure for collecting and treating the ice-melt water.
