Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery pack charging for battery replacement, and particularly relates to an ice removing device. BACKGROUND

[0002] In daily life, more and more cars have been used, and the use of a large number of fuel cars not only increases the use of some non-renewable resources, but also pollutes the environment by exhaust emission. In the face of the serious situation of the increasing imbalance between supply and demand of traditional energy and global climate warming, electric vehicles as a new energy transportation tool have emerged as the times require. Electric vehicles have become one of the strategic emerging industries supported by various countries due to the advantages of low noise, high energy utilization rate, no mobile exhaust emission, etc. With the entry of electric vehicles into the market, the cruising range has become an important influencing factor hindering the development of electric vehicles. By learning from the way of refueling for traditional vehicles, for electric vehicles, charging the battery pack with low power or directly disassembling the battery pack with low power to replace the battery pack with full power has become the key research direction to increase the cruising range of electric vehicles.

[0003] Due to the limitations of battery material technology and charging technology, it takes at least tens of minutes for a new energy vehicle to be fully charged after running out of power. For some new energy freight vehicles with large 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 for replacing the battery pack is greatly reduced compared with the charging time of the battery pack. Therefore, more and more new energy vehicles use detachable battery packs for energy supply, solving the problems of long charging time and inconvenient charging of fixed battery packs. Specifically, a plurality of locking mechanisms are installed on the bottom of the vehicle, and the installation or disassembly of the battery pack is realized by locking or unlocking the locking mechanisms and the cooperating pieces on the battery pack. Moreover, for such new energy vehicles, due to the large weight and volume of the battery pack, a special battery replacement equipment is required to disassemble and install the battery pack. However, in cold weather in the north, especially after heavy snow or heavy rain, the bottom of the vehicle is covered with a thick layer of ice, and the ice layer also wraps the locking mechanism and the bottom of the vehicle, affecting the unlocking of the locking mechanism, causing the battery pack to be frozen on the bottom of the vehicle, which is difficult to disassemble or even impossible to disassemble. This greatly increases the battery replacement time of the vehicle, causing congestion at the battery replacement station.

[0004] Therefore, before the battery pack is replaced, the ice layer of the locking mechanism needs to be melted by using a deicing device. The existing deicing device usually uses the way of conveying hot air to the ice layer covering position to remove the ice layer of the locking mechanism and the vehicle body. However, this deicing method has the following problems: because the air outlet of the deicing device is spaced apart from the ice layer, the hot air is easily affected by the external environment, especially the airflow, during the movement between the air outlet of the deicing device and the ice layer, which easily causes the heat energy loss of the hot air and affects the deicing efficiency. Meanwhile, the hot air is easily deviated by the external airflow, which affects the conveying accuracy of the hot air and thus affects the deicing efficiency. Practical new type content

[0005] The application provides a deicing device to solve the technical problems of low deicing rate and poor deicing precision of the conventional deicing device.

[0006] The technical scheme adopted by the application is as follows:

[0007] The deicing device is used for deicing the battery swap vehicle. The battery pack of the battery swap vehicle is installed at the bottom of the vehicle body by the locking mechanism to facilitate the quick replacement of the battery pack. The deicing device comprises a movable machine body and an electromagnetic heating unit arranged on the machine body. The electromagnetic heating unit can generate an alternating electromagnetic field around it. The machine body can move to the bottom of the vehicle body of the battery swap vehicle and make the bottom of the vehicle body and / or the locking mechanism heat up under the action of the alternating electromagnetic field of the electromagnetic heating unit to perform the deicing operation on the bottom of the vehicle body and / or the locking mechanism.

[0008] By adopting the technical scheme, the deicing device comprises a machine body and an electromagnetic heating unit arranged on the machine body. When deicing operation is performed, the machine body needs to be pushed to the bottom of the vehicle body to cover the locking mechanism and / or the bottom of the vehicle body into the alternating electromagnetic field generated thereby. The locking mechanism and / or the vehicle body are rapidly heated by the alternating electromagnetic field, so that the ice layer covered around the locking mechanism and / or the vehicle body is melted. Since the heat for melting the ice layer is derived from the heat energy generated by the locking mechanism and / or the vehicle body, the heat energy is transmitted to the ice layer in a solid-state conduction mode through direct contact, greatly reducing the transmission loss of the heat energy from the locking mechanism and / or the machine body to the ice layer, so that the ice layer receives the heat from the locking mechanism and / or the machine body to a greater extent, greatly increasing the ice melting efficiency. In addition, since the electromagnetic heating unit heats the locking mechanism and / or the vehicle body, it is only necessary to ensure the alignment of the electromagnetic heating unit and the locking mechanism and / or the vehicle body to realize stable heat supply, and there is no phenomenon of interference by external factors such as air flow, greatly improving the deicing precision of the deicing device. Moreover, the deicing device can adjust the heat of the locking mechanism and / or the vehicle body by adjusting the magnetic field strength of the electromagnetic heating unit, so as to adjust the ice melting speed by adjusting the heating efficiency for different thicknesses of the ice layer. Furthermore, the heating principle of the deicing device in the application is to heat the locking mechanism and / or the vehicle body by the electromagnetic heating unit, so the electromagnetic heating unit itself does not generate heat. On the one hand, this effectively reduces the influence of high temperature on the deicing device, which helps to improve the service life of the deicing device. On the other hand, the electromagnetic heating unit is not affected by the ice water dripping after the ice layer is melted, which improves the deicing stability of the deicing device.

[0009] Preferably, the electromagnetic heating unit is composed of a plurality of mutually connected induction coils; the induction coil is composed of a plurality of concentric circular coils connected in order from small to large in diameter, or the induction coil is in a spiral disc structure.

[0010] By adopting the above technical scheme, the electromagnetic heating unit is arranged as a plurality of mutually connected induction coils, which can form a more intensive alternating electromagnetic field at the coil, increase the coverage density of the alternating electromagnetic field on the locking mechanism and / or the vehicle body of the deicing area, and thus improve the heating rate of the deicing device. Arranging the induction coil as a plurality of concentric circular coils connected in order from small to large in diameter, or arranging the induction coil as a spiral disc structure, can improve the magnetic field strength and coverage area of the alternating electromagnetic field generated by the induction coil, further increase the heating speed and ice melting efficiency of the locking mechanism and / or the vehicle body, and improve the coverage uniformity of the alternating electromagnetic field, realizing uniform heating of the locking mechanism and / or the vehicle body and uniform melting of the ice layer.

[0011] Preferably, the locking mechanisms are multiple, and are arranged on the battery pack according to preset positions, the number of the induction coils is equal to the number of the locking mechanisms and is one-to-one aligned; or, the locking mechanisms are two columns, and are arranged on the two sides of the battery pack along the length direction of the battery pack, the induction coils are correspondingly arranged as two columns and are arranged in intervals corresponding to the locking mechanisms.

[0012] The arrangement of multiple locking mechanisms on the battery pack according to preset positions can realize multi-point fixing of the battery pack, improve the installation stability of the battery pack, and reduce the pressure bearing of a single locking mechanism. The one-to-one alignment of the number of the induction coils with the locking mechanisms enables each induction coil to realize synchronous heating of the corresponding locking mechanism, improves the deicing precision of the deicing device on the locking mechanism, and helps to improve the deicing efficiency. The arrangement of the locking mechanisms as two columns and along the length direction of the battery pack on the two sides of the battery pack can also enhance the load bearing stability of the battery pack and reduce the pressure bearing of the locking mechanisms. Meanwhile, the arrangement of the induction coils as two columns and in one-to-one alignment corresponding to the two columns of locking mechanisms can realize uniform heating of the locking mechanisms.

[0013] Preferably, the electromagnetic heating unit further comprises an upper plate located at the top of the fuselage and a lower plate located below the upper plate, and the induction coil is located between the upper plate and the lower plate and is fixed to the lower surface of the upper plate. Preferably, the outer edges of the upper plate and the lower plate are connected by side plates, so that the upper plate and the lower plate are sealed to form an installation cavity accommodating the induction coil.

[0014] The arrangement of the upper plate and the lower plate and the induction coil between the upper plate and the lower plate can protect the induction coil to a certain extent. The upper plate can stop the ice water falling from above, and the lower plate can prevent the induction coil from being affected by the ground protruding debris. Fixing the induction coil to the lower surface of the upper plate can shorten the distance between the induction coil and the locking mechanism and / or the fuselage, so that the locking mechanism and / or the fuselage are covered in a region where the alternating electromagnetic field is relatively dense, enabling the locking mechanism and / or the fuselage to be quickly heated and helping to improve the ice melting efficiency. On this basis, the side plates connecting the outer edges of the upper plate and the lower plate are arranged to form an installation cavity, which provides a relatively independent working space for the induction coil, further reduces the possibility of external environment interfering with the induction coil, and helps to improve the working stability of the deicing device.

[0015] Preferably, the upper surface of the upper plate is provided with at least one downwardly recessed water containing groove and a drainage groove in communication with the water containing groove. The water containing groove is used for containing the ice water melted after the vehicle body bottom and / or the locking mechanism is heated, and the drainage groove extends from the water containing groove to the outer edge of the upper plate to guide the ice water to flow out. The water containing groove and the drainage groove are arranged in a staggered manner with the electromagnetic heating unit.

[0016] By setting the water containing groove and the drainage groove, a containing space and a drainage channel are provided for the ice water after being melted by heat. Since the water containing groove is lower than the rest of the upper surface of the upper plate, the ice water dropped on the upper plate can slide to the water containing groove under the action of gravity and flow to the outside of the upper plate under the guidance of the drainage groove, so as to realize the discharge of the ice water to the outside of the upper plate, avoid the accumulation of the ice water on the upper plate, and help to reduce the cleaning pressure on the deicing device. The water containing groove and the drainage groove are respectively arranged in a staggered manner with the electromagnetic heating unit, which can avoid the unstable installation of the electromagnetic heating unit due to the unevenness of the upper plate, and help to improve the installation strength of the electromagnetic heating unit.

[0017] Preferably, the position of the upper plate where the induction coil is mounted is a mounting area, the upper plate is provided with a first flow port penetrating the upper plate, the first flow port is not on the mounting area, and the first flow port is lower than the mounting area in the height direction, the first flow port and the mounting area are connected by an inclined flow guide surface, and the lower plate is provided with a second flow port corresponding to the position of the first flow port, so that the ice water melted after the heating of the bottom of the vehicle body and / or the locking mechanism flows out through the first flow port and the second flow port.

[0018] By setting the first flow port and the second flow port, an outlet channel is provided for the ice water falling on the upper plate. Since there is a height difference between the first flow port and the mounting area, and the first flow port and the mounting area are connected by an inclined flow guide surface, when the ice water falls on the upper plate, it will slide along the flow guide surface to the first flow port under the action of gravity, and then continue to move downward under the action of gravity and flow out from the second flow port, thereby avoiding the accumulation of ice water on the upper plate, especially the mounting area, thereby avoiding the influence of the ice water on the operation of the induction coil, and helping to reduce the cleaning pressure on the deicing device.

[0019] Preferably, the number of the first flow port and the second flow port is one, and each is provided at the center position of the upper plate and the lower plate.

[0020] By setting the number of the first flow port and the second flow port to one, the processing difficulty of the upper plate and the lower plate can be reduced, and the structural strength of the upper plate and the lower plate can be maintained as much as possible. Especially for the upper plate, the upper plate with high structural strength can better bear the induction coil.

[0021] Preferably, the fuselage further comprises a base, the base is located below the electromagnetic heating unit, a lifting mechanism is arranged between the base and the electromagnetic heating unit, so that the electromagnetic heating unit can be adjusted to different heights relative to the base to deice the battery swap vehicle at different heights; and / or, a horizontal moving mechanism is arranged between the base and the electromagnetic heating unit, so that the electromagnetic heating unit can be adjusted horizontally relative to the base to align with the vehicle body bottom and / or the locking mechanism.

[0022] By arranging the base and the lifting mechanism at the bottom of the base, the base can be jacked up by the lifting mechanism to lift the electromagnetic heating unit to an appropriate height, so as to cover the locking mechanism and / or the fuselage into the alternating electromagnetic field, thereby achieving rapid heating of the locking mechanism and / or the vehicle body bottom to achieve the purpose of rapid deicing. By arranging the horizontal moving mechanism between the base and the electromagnetic heating unit, the horizontal position of the electromagnetic heating unit can be adjusted, so as to adjust the electromagnetic heating unit to a position opposite to the locking mechanism and / or the fuselage, thereby enhancing the coverage accuracy of the alternating electromagnetic field on the deicing area and improving the deicing efficiency.

[0023] Preferably, the deicing device further comprises a position detector, which can detect the height position and the horizontal position of the electromagnetic heating unit relative to the vehicle body bottom and / or the locking mechanism, so as to control the lifting mechanism and / or the horizontal moving mechanism to adjust the position of the electromagnetic heating unit.

[0024] By arranging the position detector, the alignment of the electromagnetic heating unit with the vehicle body bottom and / or the locking mechanism can be automatically detected, and the horizontal moving mechanism is controlled to adjust the horizontal position of the electromagnetic heating unit, so that the electromagnetic heating unit is aligned with the locking mechanism and / or the vehicle body bottom. When the electromagnetic heating unit is aligned with the locking mechanism and / or the vehicle body bottom, the lifting mechanism is controlled to lift the electromagnetic heating unit to a specified position, thereby realizing the coverage of the alternating electromagnetic field on the locking mechanism and / or the vehicle body bottom. The operator does not need to observe the relative position of the electromagnetic heating unit with the locking mechanism and / or the vehicle body bottom, which reduces the alignment difficulty of the operator and helps to improve the deicing efficiency.

[0025] Preferably, when the electromagnetic heating unit is in the heating position, the distance between the electromagnetic heating unit and the vehicle body bottom and / or the locking mechanism is 10-30mm.

[0026] The distance between the electromagnetic heating unit and the bottom of the vehicle body and / or the locking mechanism is set to 10-30mm, so that the bottom of the vehicle body and / or the locking mechanism is in the dense area of the alternating electromagnetic field, the rapid heating of the bottom of the vehicle body and / or the locking mechanism can be achieved, the ice melting speed is improved, and there is a certain distance between the bottom of the vehicle body and / or the locking mechanism and the electromagnetic heating unit, which reduces the influence of the bottom of the vehicle body and / or the locking mechanism on the electromagnetic heating unit in the high temperature state.

[0027] Preferably, the upper plate and / or the lower plate are made of glass fiber material.

[0028] The upper plate and the lower plate made of glass fiber material have good heat insulation performance, which can effectively reduce the heat transfer from the locking mechanism and / or the vehicle body in the high temperature state to the electromagnetic heating unit, and help to improve the service life of the electromagnetic heating unit.

[0029] Preferably, the deicing device further comprises a power supply unit for providing power for the induction coil, the power supply unit is arranged on the vehicle body and located on the side away from the electromagnetic heating unit; the vehicle body comprises a first bearing part for bearing the electromagnetic heating unit and a second bearing part for bearing the power supply unit, and a through communication channel is arranged between the first bearing part and the second bearing part, so that the cable of the power supply unit passes through the communication channel and is connected with the induction coil.

[0030] By arranging the first bearing part, the second bearing part and the communication channel, the electromagnetic heating unit, the power supply unit and the cable are provided with relatively independent installation spaces respectively, so as to avoid mutual interference between the components, and the first bearing part, the second bearing part and the communication channel can protect the electromagnetic heating unit, the power supply unit and the cable, which helps to improve the working stability of the deicing device.

[0057] like Figures 1 to 10 As shown, a deicing device is used to de-ice a battery-swapping vehicle. The battery pack of the battery-swapping vehicle is installed on the bottom of the vehicle body through a locking mechanism to facilitate quick replacement of the battery pack. The deicing device includes a movable fuselage 1 and an electromagnetic heating unit 2 installed on the fuselage 1. The electromagnetic heating unit 2 can generate an alternating electromagnetic field around it. The fuselage 1 can move to the bottom of the vehicle body of the battery-swapping vehicle and heat the bottom of the vehicle body and / or the locking mechanism under the action of the alternating electromagnetic field of the electromagnetic heating unit 2 to perform de-icing operations on the bottom of the vehicle body and / or the locking mechanism.

[0058] The deicing device of the present application comprises a machine body 1 and an electromagnetic heating unit 2 arranged on the machine body 1. When deicing operation is performed, the machine body 1 needs to be pushed to the bottom of the vehicle body to cover the locking mechanism and / or the bottom of the vehicle body into the alternating electromagnetic field generated thereby. The locking mechanism and / or the vehicle body are rapidly heated by the alternating electromagnetic field, thereby melting the ice layer covered therearound. Since the heat for melting the ice layer is derived from the heat energy generated by the locking mechanism and / or the vehicle body, the heat energy is transmitted to the ice layer by direct contact in a solid state conduction manner, greatly reducing the transmission loss of the heat energy from the locking mechanism and / or the vehicle body to the ice layer, so that the ice layer receives a larger amount of heat from the locking mechanism and / or the vehicle body, greatly increasing the ice melting efficiency. In addition, since the electromagnetic heating unit 2 heats the locking mechanism and / or the vehicle body, it is only necessary to ensure the alignment of the electromagnetic heating unit 2 with the locking mechanism and / or the vehicle body to achieve stable heat supply, and there is no phenomenon of interference by external factors such as air flow, greatly improving the deicing precision of the deicing device. Moreover, the deicing device can adjust the heat of the locking mechanism and / or the vehicle body by adjusting the magnetic field strength of the electromagnetic heating unit 2, so as to adjust the ice melting speed by adjusting the heating efficiency for different thicknesses of ice layer. Furthermore, the heating principle of the deicing device in the present application is to heat the locking mechanism and / or the vehicle body by the electromagnetic heating unit 2. Therefore, the electromagnetic heating unit 2 itself does not generate heat, which on the one hand effectively reduces the influence of high temperature on the deicing device, and on the other hand prevents the electromagnetic heating unit 2 from being affected by the ice water dripping after the ice layer is melted, thereby improving the deicing stability of the deicing device.

[0059] Specifically, the electromagnetic heating unit 2 forms a surrounding alternating electromagnetic field around its periphery after being energized. The alternating electromagnetic field causes the metal to generate induced eddy current when covering the metal, and the heat generated by the eddy current heats the metal. The electromagnetic heating unit 2 in the present application covers the locking mechanism and / or the bottom of the vehicle body by the alternating electromagnetic field around its periphery, thereby heating and warming the locking mechanism and / or the bottom of the vehicle body to achieve the ice melting effect.

[0060] The structure of the electromagnetic heating unit 2 in the present application is not limited, and it can adopt any one of the following embodiments:

[0061] Embodiment one: as shown in Figure 2 , Figure 3 The electromagnetic heating unit 2 is composed of a plurality of induction coils 21 connected to each other; and the induction coil 21 is composed of a plurality of concentric circular coils connected in order from small to large in diameter.

[0062] The electromagnetic heating unit 2 is arranged as a plurality of induction coils 21 connected with each other, so that a more intensive alternating electromagnetic field can be formed at the coils, increasing the coverage density of the alternating electromagnetic field on the locking mechanism and / or the vehicle body in the deicing area, thereby improving the heating rate of the deicing device; and the induction coil 21 is arranged as a plurality of concentric circular coils connected in sequence from small to large, so as to improve the magnetic field strength and coverage area of the alternating electromagnetic field generated by the induction coil 21, further increasing the heating speed and ice melting efficiency of the locking mechanism and / or the vehicle body, while improving the coverage uniformity of the alternating electromagnetic field, achieving uniform heating of the locking mechanism and / or the vehicle body, and achieving uniform melting of the ice layer.

[0063] Embodiment two: as shown in Figure 4 , Figure 5 , the electromagnetic heating unit 2 is composed of a plurality of induction coils 21 connected with each other; the induction coil 21 is in the form of a spiral disc.

[0064] The same as embodiment one is that the induction coil 21 is arranged in the form of a spiral disc, which aims to improve the magnetic field strength and coverage area of the alternating electromagnetic field generated by the induction coil 21, thereby enhancing the heating speed of the locking mechanism and / or the vehicle body, and thereby improving the ice melting efficiency.

[0065] In embodiment one and embodiment two, the arrangement form of the locking mechanism and the arrangement mode of the induction coil 21 are not limited, which can adopt any one of the following embodiments:

[0066] Embodiment one: as shown in Figure 6 , Figure 7 , the locking mechanism is provided in a plurality of preset positions on the battery pack, and the number of the induction coils 21 is equal to the number of the locking mechanisms and is one-to-one aligned. Arranging the locking mechanism in a plurality of preset positions on the battery pack can achieve multi-point fixation of the battery pack, improve the installation stability of the battery pack, and reduce the bearing pressure of the single locking mechanism, while the number of the induction coils 21 is one-to-one aligned with the locking mechanisms, so that each induction coil 21 can realize synchronous heating of the corresponding locking mechanism, thereby improving the deicing precision of the deicing device on the locking mechanism and helping to improve the deicing efficiency.

[0067] Embodiment two: as shown in Figure 2 , Figure 4 , the locking mechanism is arranged in two rows along the length direction of the battery pack on both sides of the battery pack, and the induction coil 21 is correspondingly arranged in two rows and is arranged at intervals corresponding to the locking mechanism. Arranging the locking mechanism in two rows and distributing it along the length direction of the battery pack on both sides of the battery pack can also enhance the bearing stability of the battery pack and reduce the bearing pressure of the locking mechanism, while the induction coil 21 is arranged in two rows and is arranged one-to-one corresponding to the two rows of locking mechanisms, thereby achieving uniform heating of the locking mechanism.

[0068] As a preferred example under the first embodiment and the second embodiment, as shown in Figure 8 The electromagnetic heating unit 2 further comprises an upper plate 22 located at the top of the fuselage 1 and a lower plate 23 located below the upper plate 22, and the induction coil 21 is located between the upper plate 22 and the lower plate 23 and fixed to the lower surface of the upper plate 22.

[0069] By setting the upper plate 22 and the lower plate 23 and arranging the induction coil 21 between the upper plate 22 and the lower plate 23, the induction coil 21 can be protected to a certain extent, the upper plate 22 can stop the ice water from falling from above, and the lower plate 23 can prevent the induction coil 21 from being affected by the protruding sundries on the ground; and by fixing the induction coil 21 to the lower surface of the upper plate 22, the distance between the induction coil 21 and the locking mechanism and / or the fuselage can be shortened, so that the locking mechanism and / or the fuselage are covered in the area where the alternating electromagnetic field is relatively dense, and the locking mechanism and / or the fuselage can be quickly heated, which helps to improve the ice melting efficiency.

[0070] Preferably, the outer edges of the upper plate 22 and the lower plate 23 are connected by the side plate 24, so that the upper plate 22 and the lower plate 23 are sealed to form a mounting cavity accommodating the induction coil 21.

[0071] The side plate 24 is arranged to connect the outer edges of the upper plate 22 and the lower plate 23 and form the mounting cavity, which provides a relatively independent working space for the induction coil 21, further reduces the possibility of external environment interfering with the induction coil 21, and helps to improve the working stability of the ice melting device.

[0072] As a preferred example under the present embodiment, as shown in Figure 10 The upper surface of the upper plate 1 is provided with at least one downwardly recessed water containing groove 8 and a drainage groove 9 communicating with the water containing groove 8, the water containing groove 8 is used to contain the ice water melted after the bottom of the fuselage and / or the locking mechanism is heated, the drainage groove 9 extends from the water containing groove 8 to the outer edge of the upper plate 22 to guide the ice water to flow out, and the water containing groove 8 and the drainage groove 9 are arranged in a staggered manner with the electromagnetic heating unit 2.

[0073] By arranging the water containing groove 8 and the drainage groove 9, a containing space and a drainage channel are provided for the ice water melted by heat, since the water containing groove 8 is lower than the rest of the upper surface of the upper plate 22, the ice water falling on the upper plate 22 can slide into the water containing groove 8 under the action of gravity and flow out of the upper plate 22 under the guidance of the drainage groove 9, so as to realize the discharge of the ice water outside the upper plate 22, avoid the accumulation of the ice water on the upper plate 22, and help to reduce the cleaning pressure on the ice melting device. And the water containing groove 8 and the drainage groove 9 are arranged in a staggered manner with the electromagnetic heating unit 2, which can avoid the unstable installation of the electromagnetic heating unit 2 due to the unevenness of the upper plate 22, and help to improve the installation strength of the electromagnetic heating unit 2.

[0074] The number and arrangement of the drainage grooves are not limited in the example, and one drainage groove can be arranged for each water storage groove, or multiple drainage grooves can be arranged for each water storage groove. The drainage grooves can extend linearly to the outer edge of the upper plate, or can extend to the outer edge of the upper plate in a bent manner.

[0075] As another preferred example under the present embodiment, as shown in Figure 1 The position where the upper plate 22 is installed with the induction coil 21 is the installation area 7. The upper plate 22 is provided with a first overflow port 3 penetrating the upper plate 22. The first overflow port 3 is not located on the installation area 7, and the first overflow port 3 is lower than the installation area 7 in the height direction. The first overflow port 3 and the installation area 7 are connected by a sloping flow guide surface. The lower plate 23 is provided with a second overflow port corresponding to the position of the first overflow port 3, so that the melted ice water of the vehicle body bottom and / or the locking mechanism after being heated can flow out through the first overflow port 3 and the second overflow port.

[0076] By arranging the first overflow port 3 and the second overflow port, an outlet channel is provided for the ice water falling on the upper plate 22. Since there is a height difference between the first overflow port 3 and the installation area 7, and the first overflow port 3 and the installation area 7 are connected by a sloping flow guide surface, when the ice water falls on the upper plate 22, it will slide down the flow guide surface to the first overflow port 3 under the action of gravity, and then continue to move downward under the action of gravity and flow out from the second overflow port. This avoids the accumulation of ice water on the upper plate 22, especially the installation area 7, thereby avoiding the influence of ice water on the operation of the induction coil 21, and helping to reduce the cleaning pressure on the ice melting device.

[0077] The number and arrangement of the overflow ports are not limited in the example. In one way, as shown in Figure 1 The number of the first overflow port 3 and the second overflow port is one, and they are respectively arranged at the center positions of the upper plate 22 and the lower plate 23. Arranging the number of the first overflow port 3 and the second overflow port to be one can reduce the processing difficulty of the upper plate 22 and the lower plate 23, and maintain the structural strength of the upper plate 22 and the lower plate 23 as much as possible. Especially for the upper plate 22, the upper plate 22 with higher structural strength can better bear the induction coil 21. In addition, arranging the first overflow port 3 and the second overflow port at the center positions of the upper plate 22 and the lower plate 23 makes the distance from the first overflow port 3 to each part of the upper surface of the upper plate 22 relatively uniform, the slope of each part of the flow guide surface is the same, and the ice water can easily slide to the first overflow port 3. In another way, the number of the first overflow port 3 and the second overflow port is multiple, and multiple first overflow ports 3 and second overflow ports are arranged in position on the upper plate 22 and the lower plate 23. Arranging the number of the first overflow port 3 and the second overflow port to be multiple can improve the collection efficiency of the ice water on the upper plate 22 and reduce the risk of ice water accumulation on the upper plate 22.

[0078] Preferably, the machine body 1 further comprises a base, the base is located below the electromagnetic heating unit 2, and a lifting mechanism is arranged between the base and the electromagnetic heating unit 2, so that the electromagnetic heating unit 2 can be adjusted to different heights relative to the base to deice the battery swap vehicle at different heights. By arranging the base and the lifting mechanism at the bottom of the base, the base can be jacked up by the lifting mechanism to lift the electromagnetic heating unit 2 to an appropriate height, so that the locking mechanism and / or the vehicle body is covered in the alternating electromagnetic field, thereby achieving rapid heating of the locking mechanism and / or the bottom of the vehicle body to achieve the purpose of rapid deicing.

[0079] The structure and type of the lifting mechanism are not limited in the present application, which can adopt a jack, a hydraulic jacking machine, an electric jacking machine, etc.

[0080] Further, a horizontal movement mechanism is arranged between the base and the electromagnetic heating unit 2, so that the electromagnetic heating unit 2 can be adjusted in horizontal position relative to the base to be aligned with the bottom of the vehicle body and / or the locking mechanism.

[0081] By arranging the horizontal movement mechanism between the base and the electromagnetic heating unit 2, the horizontal position of the electromagnetic heating unit 2 can be adjusted, so that the electromagnetic heating unit 2 is adjusted to a position aligned with the locking mechanism and / or the vehicle body, thereby enhancing the coverage accuracy of the alternating electromagnetic field on the deicing area and improving the deicing efficiency.

[0082] Preferably, the horizontal movement mechanism can be arranged between the base and the electromagnetic heating unit 2 and below the lifting mechanism, and the horizontal movement mechanism drives the lifting mechanism and the electromagnetic heating unit to move in the horizontal direction until they are aligned with the locking mechanism and / or the bottom of the vehicle body.

[0083] Further, the horizontal movement mechanism comprises a driving motor and a lead screw, and the rotating output shaft of the driving motor drives the lead screw to move horizontally, thereby driving the lifting mechanism and the electromagnetic heating unit horizontally.

[0084] Preferably, a plurality of universal wheels are arranged below the base, so that when the operator pushes the deicing device to move, the universal wheels can increase the smoothness of the deicing device, so that the deicing device can move in all directions.

[0085] Further, the deicing device further comprises a position detector, which can detect the height position and the horizontal position of the electromagnetic heating unit 2 relative to the bottom of the vehicle body and / or the locking mechanism, so as to control the lifting mechanism and / or the horizontal movement mechanism to adjust the position of the electromagnetic heating unit 2.

[0086] By setting the position detector, the alignment of the electromagnetic heating unit 2 with the vehicle body bottom and / or the locking mechanism can be automatically detected, and the horizontal moving mechanism is controlled to adjust the horizontal position of the electromagnetic heating unit 2, so that the electromagnetic heating unit 2 is aligned with the locking mechanism and / or the vehicle body bottom. When the alignment of the electromagnetic heating unit 2 with the locking mechanism and / or the vehicle body bottom is completed, the lifting mechanism is then controlled to lift the electromagnetic heating unit 2 to the specified position, thereby realizing the coverage of the alternating electromagnetic field on the locking mechanism and / or the vehicle body bottom. The operator does not need to observe the relative position of the electromagnetic heating unit 2 with the locking mechanism and / or the vehicle body bottom, which reduces the alignment difficulty of the operator and helps to improve the deicing efficiency.

[0087] Further, when the electromagnetic heating unit 2 is in the heating position, the distance between the electromagnetic heating unit 2 and the vehicle body bottom and / or the locking mechanism is 10-30mm. By setting the distance between the electromagnetic heating unit 2 and the vehicle body bottom and / or the locking mechanism to 10-30mm, the vehicle body bottom and / or the locking mechanism is in the dense area of the alternating electromagnetic field, which can realize the rapid heating of the vehicle body bottom and / or the locking mechanism and improve the ice melting speed. Moreover, there is a certain distance between the vehicle body bottom and / or the locking mechanism and the electromagnetic heating unit 2, which reduces the influence of the vehicle body bottom and / or the locking mechanism on the electromagnetic heating unit 2 in the high-temperature state. In the embodiment, the distance between the electromagnetic heating unit 2 and the vehicle body bottom and / or the locking mechanism can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 20mm, 29mm, 29.1mm, etc., any value between 10-30mm.

[0088] Preferably, the upper plate 22 and / or the lower plate 23 are made of glass fiber material. The upper plate 22 and the lower plate 23 made of glass fiber material have good heat insulation performance, which can effectively reduce the heat transfer from the locking mechanism and / or the vehicle body in the high-temperature state to the electromagnetic heating unit 2, and help to improve the service life of the electromagnetic heating unit 2.

[0089] As a preferred embodiment of the present application, as shown in Figure 9 The deicing device further includes a power supply unit for providing power for the induction coil 21, which is arranged on the fuselage 1 and located away from the electromagnetic heating unit 2. The fuselage 1 includes a first bearing part 4 for bearing the electromagnetic heating unit 2 and a second bearing part 5 for bearing the power supply unit. A communication passage 6 is arranged between the first bearing part 4 and the second bearing part 5, so that the cable of the power supply unit passes through the communication passage 6 and is connected with the induction coil 21.

[0090] By setting the first bearing part 4, the second bearing part 5 and the communication channel 6, the electromagnetic heating unit 2, the power supply unit and the cable are provided with relatively independent installation space respectively, avoiding mutual interference between the components, and the first bearing part 4, the second bearing part 5 and the communication channel 6 can protect the electromagnetic heating unit 2, the power supply unit and the cable, which helps to improve the working stability of the deicing device.

[0091] Preferably, the cable is made of flexible high-temperature-resistant insulating material, such as silicone rubber, fluororubber, ceramic aerogel, polytetrafluoroethylene and the like.
