Description

Technical Field

[0001] This application belongs to the field of new energy vehicle technology, specifically relating to a de-icing device. Background Technology

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

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

[0004] Therefore, before replacing the battery pack, a de-icing device is needed to melt the ice layer on the locking mechanism. During the de-icing operation, the de-icing device needs to be pushed into the bottom of the vehicle body and the air outlet unit needs to be aligned with the locking mechanism. Then, the hot air sprayed by the air outlet unit will melt the ice layer on the locking mechanism. However, due to the limited observation space, it is often inconvenient for operators to observe the alignment of the air outlet unit and the locking mechanism. Therefore, a lot of time needs to be spent aligning the air outlet unit and the locking mechanism before the de-icing operation, which greatly affects the de-icing efficiency and is prone to misalignment, thus affecting the de-icing effect. Summary of the Invention

[0005] This application provides a de-icing device to solve the technical problems of difficulty in aligning the de-icing device and poor heating accuracy when de-icing the bottom locking mechanism of a battery swapping vehicle in cold weather.

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

[0007] A de-icing device is disclosed for de-icing a battery swapping vehicle. The battery pack of the battery swapping vehicle is installed at the bottom of the vehicle body via a locking mechanism to facilitate quick battery swapping. The de-icing device comprises a movable body, an air outlet unit installed on the body, and a positioning component. The body is movable to the bottom of the vehicle body, such that the air outlet unit is positioned below the locking mechanism to blow hot air towards it. The positioning component is movably connected to the body and can avoid obstructing the vehicle body when the body enters the bottom of the vehicle body. Furthermore, after the body reaches the de-icing position, it can cooperate with the side of the vehicle body to align the air outlet unit with the locking mechanism.

[0008] By adopting the above technical solution, when de-icing the locking mechanism, the air outlet unit is first moved to the bottom of the locking mechanism by moving the main body. After the air outlet unit is aligned with the locking mechanism, the air outlet unit sprays hot air to the locking mechanism, thereby achieving thermal melting of the ice layer at the locking mechanism. The positioning component engages with the side of the vehicle body after the machine reaches the de-icing position. Once engaged, the machine body reaches the de-icing position where the air outlet unit aligns with the locking mechanism, enabling precise air supply from the air outlet unit to the locking mechanism. Therefore, operators can determine the alignment of the air outlet unit simply by observing the engagement of the positioning component with the vehicle body, eliminating the need to observe the relative positions of the air outlet unit and locking mechanism from the bottom of the vehicle body. This significantly reduces the difficulty of adjusting the position of the de-icing device during de-icing operations. On one hand, it shortens the preparation time required for position calibration of the air outlet unit before de-icing, thus improving de-icing efficiency. On the other hand, when the positioning component engages with the side of the vehicle body, the air outlet unit is directly opposite the locking mechanism, avoiding the possibility of positional deviations caused by manual alignment, further improving the de-icing efficiency of the device.

[0009] The positioning component is rotatably connected to the body and can switch between a first position and a second position to be in a corresponding horizontal or vertical state relative to the body. The de-icing device also includes a control mechanism connected to the positioning component. When the body enters the bottom of the vehicle body, the control mechanism controls the positioning component to switch to the first position to avoid interference with the vehicle body. When the body reaches the de-icing position, the control mechanism controls the positioning component to switch to the second position to abut against the side of the vehicle body.

[0010] By adopting the above technical solution, when moving the machine body, the positioning component is switched to the first position by the control mechanism to allow the machine body to freely enter and exit the bottom of the battery swapping vehicle, avoiding the positioning component from touching the chassis or other components that would affect the movement of the machine body. When the machine body reaches the de-icing position, the positioning component is switched from the first position to the second position by the control mechanism to achieve positioning with the side of the vehicle body. In this way, the operator can control the positioning component to switch between the first and second positions by operating the control mechanism to adapt to the movement needs of the machine body and the positioning needs of the air outlet unit, ensuring that the positioning component can achieve the positioning function of the air outlet unit while avoiding the positioning component affecting the movement of the machine body.

[0011] When the positioning component is in a vertical position, the highest point of the positioning component is not lower than the lowest point of the side of the vehicle body.

[0012] By adopting the above technical solution, the positioning component can position the air outlet unit by abutting against the side of the vehicle body. After the machine body is fully pushed into the bottom of the vehicle body, the operator switches the positioning component from a horizontal state to a vertical state through the control mechanism. When the positioning component abuts against the side of the vehicle body, the operator will receive kinetic or audible feedback, indicating that the positioning component has cooperated with the side of the vehicle body. Alternatively, the operator can drive the machine body to make a reverse movement to pull it away from the bottom of the vehicle body. If the machine body and the vehicle body cannot move in the opposite direction due to the stop of the positioning component, it proves that the positioning component has cooperated with the side of the vehicle body. That is, the operator does not need to observe the cooperation state between the positioning component and the vehicle body to know the cooperation status of the positioning component and the vehicle body, thereby knowing the positioning status of the air outlet unit, reducing the difficulty of de-icing work. In addition, since the highest point of the positioning component is not lower than the lowest point of the side of the vehicle body, the positioning component can also play the role of stopping the airflow on the side of the vehicle body, reducing the possibility of interference from the airflow on the side of the vehicle body or other factors on the air supply of the air outlet unit, which helps to improve the de-icing efficiency of the de-icing device.

[0013] The control mechanism includes a first linkage, a second linkage, and a control element. The first end of the first linkage is rotatably connected to the positioning element, the second end of the first linkage is rotatably connected to the third end of the second linkage, and the fourth end of the second linkage is rotatably connected to the machine body. The control element is connected to the second end and the third end and can drive the position of the rotation point between the second end and the third end to change, thereby causing the first linkage and the second linkage to rotate, thus enabling the positioning element to switch between the first position and the second position.

[0014] By adopting the above technical solution, the control component can simultaneously act on the second end of the first linkage and the third end of the second linkage, driving the first and second linkages to rotate synchronously, thereby enabling the positioning component to switch between the first and second positions. During this process, the first linkage and the positioning component, the second linkage and the positioning component, and the first linkage and the second linkage are all rotatably connected, thus reducing the frictional resistance that the control component needs to overcome when driving the first and second linkages to move, making the switching of the positioning component between the first and second positions smoother. In addition, since the first and second linkages rotate synchronously and move closer to each other under the drive of the control component, the rotation speed of the positioning component, i.e., the switching speed from the first position to the second position, is accelerated, thereby reducing the working stroke of the control component when driving the positioning component to switch positions, which helps to optimize the structural design of the control mechanism.

[0015] The control mechanism further includes an elastic reset member disposed between the positioning member and the body. The elastic reset member keeps the positioning member in the second position. When the control member applies a force, it can overcome the force of the elastic reset member and drive the positioning member to switch from the second position to the first position. When the control member does not apply a force or removes the force, the force of the elastic reset member keeps the positioning member in the second position or switches it from the first position to the second position.

[0016] By adopting the above technical solution, once the machine body is fully pushed into the bottom of the vehicle body, the operator only needs to remove the force applied to the control component. The positioning component will then switch from the first position to the second position under the elastic action of the elastic reset component, eliminating the need for the operator to perform a position switching operation on the positioning component from the first position to the second position. In addition, the elastic force of the elastic reset component can also maintain the positioning component in the second position. During the de-icing process of the de-icing device, the operator does not need to apply additional force to maintain the vertical state of the positioning component, thus optimizing the user experience of the de-icing device.

[0017] The elastic reset component is a spring hinge, which includes a first leaf, a second leaf, and a spring connected between the first leaf and the second leaf. The positioning component is fixedly connected to the first leaf, and the body is fixedly connected to the second leaf. The force of the spring causes the first leaf to move the positioning component to remain in the second position.

[0018] By adopting the above technical solution, the elastic reset component is set as a spring hinge, and the first and second leaf pieces are fixedly connected to the positioning component and the machine body respectively. This increases the contact area between the elastic reset component, the positioning component, and the machine body, allowing the elastic reset component to provide more stable support to the positioning component. The spring applies elastic force to the first and second leaf pieces to maintain the angle between the first and second leaf pieces, thereby maintaining the angle between the positioning component and the machine body.

[0019] Along the length of the body, the body has an active end and a driven end arranged opposite to each other. The active end is subjected to a force to drive the driven end from one side of the vehicle body into the bottom of the vehicle body. The positioning member is disposed on the driven end. The active end is provided with a vertically extending bearing part. When the body moves to the bottom of the battery swapping vehicle body, the positioning member and the bearing part abut against the two sides of the battery swapping vehicle body respectively.

[0020] By adopting the above technical solution, the active end and the driven end are respectively set on the front and rear sides of the body, and the bearing part and the positioning part are respectively set on the active end and the driven end. On the one hand, it provides a force application position for the operator to drive the body. The operator can move the body by applying the driving force to the bearing part, which reduces the difficulty of moving the body. In addition, the positioning part and the bearing part abut against the sides of the battery swapping vehicle body, so that the positioning part and the bearing part can respectively stop the airflow from the side of the vehicle body to the bottom of the vehicle body, reduce the impact of the airflow on the hot air sprayed by the air outlet unit, improve the heat supply stability of the air outlet unit to the locking mechanism, and at the same time help reduce the diffusion of heat from the bottom of the vehicle body to the side of the vehicle body, which helps to further improve the de-icing speed of the de-icing device.

[0021] The air outlet unit extends along the width direction of the body and neither end of the air outlet unit extends beyond the positioning member and / or the supporting part in the width direction of the body.

[0022] By adopting the above technical solution, the supporting part and the positioning part can block the side space of the air outlet unit to the greatest extent, which improves the blocking effect of the supporting part and the positioning part on the airflow and debris from the side of the vehicle body, and greatly improves the stability of the hot air output of the air outlet unit.

[0023] Two of each of the first linkage, the second linkage, and the control component are provided, and they are symmetrically arranged at both ends of the positioning component along the length direction of the machine body. The control mechanism also includes a synchronous shaft, which is connected to the end of the two control components away from the rotation point of the first linkage and the second linkage.

[0024] By adopting the above technical solution, the number of the first linkage, the second linkage, and the control component is set to two, and they are respectively located at both ends of the positioning component. This makes the rotational force applied to the positioning component more uniform and reduces the force pressure required for a single control component to drive the positioning component to rotate. In addition, since a synchronous shaft is provided and both control components are connected to the synchronous shaft, the operator only needs to apply force to the synchronous shaft. The synchronous shaft rotates and simultaneously drives the two control components to move, thereby driving the first linkage and the second linkage located on both sides of the positioning component respectively. This eliminates the need to drive two control components to work at the same time, reduces the difficulty of the operator's work, and optimizes the structural design of the de-icing device.

[0025] The control mechanism further includes a control lever and two third linkages. The two third linkages are arranged at both ends of the synchronous shaft along the width direction of the machine body and are respectively connected to the control components at the corresponding ends. The control lever is fixed to the synchronous shaft.

[0026] By adopting the above technical solution, during the switching process of the positioning component from the second position to the first position driven by the control mechanism, the two third linkage components fixedly connected to the synchronous shaft rotate synchronously when the synchronous shaft is rotated. Since the end of the third linkage component away from the synchronous shaft is connected to the control component, only a small rotation angle of the synchronous shaft is needed to drive the end of the third linkage component away from the synchronous shaft to have a large stroke, thereby achieving a large stroke change of the control component connected to the third linkage component. Subsequently, the positioning component is moved through the first linkage component and the second linkage component. That is, the positioning component can be switched from the second position to the first position with a small rotation of the synchronous shaft, reducing the working space required for the control mechanism to move the positioning component and facilitating de-icing. The miniaturization of the device, coupled with the fact that operators only need a small force stroke to move the positioning component to the first position, optimizes the structural design of the de-icing device. Furthermore, since the rotation trajectory of the synchronous shaft is fixed, the synchronous rotation trajectory of the third linkage component as it rotates with the synchronous shaft is also fixed. This ensures that the movement trajectory of the control component connected to the third linkage component is constant. Therefore, by rotating the synchronous shaft, the movement of the two control components along a fixed trajectory can be achieved to move the positioning component from the second position to the first position. This avoids the phenomenon of force deviation of the control component on the first and second linkage components caused by operator force deviation or other factors, thus ensuring the stability of the positioning component during the switching process from the second position to the first position.

[0027] The control component is a rope. A fixed pulley is provided on the machine body corresponding to the active end, and a limiting shaft is provided corresponding to the driven end. The rope is led out from the third linkage, wound around the fixed pulley, and extends to the driven end, passing through the through hole on the limiting shaft and connecting with the second end and the third end. Preferably, the machine body is also provided with a plurality of threading pipes located between the fixed pulley and the limiting shaft and spaced apart. The threading pipes are hollow inside to form a threading channel for the rope to pass through.

[0028] By adopting the above technical solution, the control component is designed as a rope, allowing its extension direction to be adjusted according to the structural layout of the de-icing device. This significantly improves the adaptability of the control component to the de-icing device structure. Furthermore, by installing a fixed pulley at the active end, the control component, after being led out from the third linkage, smoothly rotates its extension direction towards the driven end. When the control component moves under the influence of the third linkage, there is rolling friction between it and the fixed pulley, resulting in low frictional force on the control component. This reduces wear on the control component and also lowers the force required to drive its movement via the third linkage, allowing the operator to move more easily. The control component easily drives the first and second linkage components to move. Furthermore, by setting a limiting shaft at the driven end, the extension direction of the control component towards the first and second linkage components can be adjusted by the extension direction of the limiting shaft, thereby adjusting the force angle applied by the control component to the second and third ends, further optimizing the driving effect of the control component on the positioning component. Moreover, multiple wiring conduits set on the side of the machine body, and the wiring channel formed by the cooperation of these conduits, provide a fixed guiding function for the extension of the control component at the active and driven ends, allowing the control component to extend and retract along the extension direction of the wiring channel under the drive of the third linkage component, thus preventing misalignment of the control component.

[0029] Along the width direction of the machine body, a rotating seat is provided on one side of the bearing part. The rotating seat has an opening on the side away from the driven end. When the control lever rotates from its original position where it is disengaged from the rotating seat to a mating position where it engages with the rotating seat within the opening, the positioning member switches from the second position to the first position.

[0030] By adopting the above technical solution, before moving the machine body to the bottom of the vehicle body, the control lever is first rotated to a position that cooperates with the rotating seat. At this time, the positioning component switches from the second position to the first position, that is, it is in a horizontal state. At this time, the machine body can be moved to the bottom of the vehicle body. After the machine body has completely moved to the bottom of the vehicle body, the cooperation between the rotating lever and the rotating seat is released, and the control lever is rotated back to the original position. At this time, the positioning component switches from the first position to the second position and cooperates with the side of the vehicle body to achieve positioning of the machine body, thereby locking the air outlet unit in the de-icing position.

[0031] The control lever includes a first lever and a second lever connected together. The first lever is located above the second lever, and the diameter of the first lever is larger than the diameter of the second lever to form a boss surface at the connection between the first lever and the second lever. The diameter of the opening is smaller than that of the first lever and larger than that of the second lever. Vertically upward baffles are provided on both sides of the opening, and the gap between the two baffles is equal to the diameter of the opening. When the control lever is in the mating position, the boss surface mates with the bearing surfaces on both sides of the opening, and the baffles can restrict the first lever to prevent the control lever from disengaging from the rotating seat.

[0032] By adopting the above technical solution, during the transfer of the control lever from its original position to its initial position, the second lever is aligned with the opening, and the control lever is rotated to the mating position through the opening. Then, the first lever is aligned with the opening. At this time, the first lever is restricted within the rotating seat by the stop action of the two baffles, thereby temporarily fixing the control lever by the rotating seat, so that the positioning component is in the first position. In this way, when pushing the machine body into the bottom of the vehicle body, the control lever locks the positioning component in the first position under the limiting action of the rotating seat. The operator does not need to apply additional control force to the control lever to maintain the horizontal state of the positioning component, so that all attention can be focused on pushing the machine body to move, which helps to improve the stability of the machine body movement. In addition, when the machine body has completely moved to the bottom of the vehicle body, the control lever is adjusted until the second lever is aligned with the opening, and the control lever is rotated from the mating position to the original position through the opening. At this time, the positioning component switches from the first position to the second position to mate with the side of the vehicle body.

[0033] The supporting part is equipped with a heating unit, which provides hot air to the air outlet unit through a transmission pipe.

[0034] By adopting the above technical solution, the heating unit is set inside the support section. In addition to cooperating with the side of the vehicle body to achieve multiple positioning of the air outlet unit and the function of wind deflection, the support section also integrates the function of providing an installation position for the heating unit. The functions are further integrated, and the structural design of the de-icing device is optimized. In addition, setting the heating unit inside the support section realizes the concealed layout of the heating unit, reduces the area of ​​the heating unit exposed on the outside of the de-icing device, and reduces the probability that ice water sliding off the locking mechanism will affect the heating unit.

[0035] The positioning member has a flexible anti-collision pad on the side facing the vehicle body; and / or, the bearing part has a flexible anti-collision pad on the side facing the vehicle body.

[0036] By adopting the above technical solution, a flexible anti-collision pad is provided on the side of the positioning component facing the vehicle body. When the positioning component switches from the first position to the second position, the flexible anti-collision pad can absorb the impact force between the positioning component and the side of the vehicle body caused by the rotation of the positioning component, reduce the kinetic energy impact on the side of the vehicle body and the positioning component, ensure the structural strength of the positioning component, and avoid the scraping caused by the positioning component abutting against the side of the vehicle body. Similarly, a flexible anti-collision pad is provided on the side of the load-bearing part facing the vehicle body. When the load-bearing part abuts against the side of the vehicle body, the flexible anti-collision pad can absorb the impact force brought about by the mutual connection between the two, and can avoid the scraping caused by the abutting between the load-bearing part and the side of the vehicle body.

[0037] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0038] When de-icing the locking mechanism, the air outlet unit is first moved to the bottom of the locking mechanism by moving the main body. After the air outlet unit is aligned with the locking mechanism, the heating unit delivers hot air to the air outlet unit. The hot air is then sprayed through the air outlet unit to the locking mechanism, thereby melting the ice layer at the locking mechanism. The positioning component engages with the side of the vehicle body after the machine reaches the de-icing position. Once engaged, the air outlet unit reaches the de-icing position opposite the locking mechanism, achieving precise air supply from the air outlet unit to the locking mechanism. Therefore, operators can determine the position of the air outlet unit simply by observing the engagement of the positioning component with the vehicle body, eliminating the need to observe the relative position of the air outlet unit and the locking mechanism from the bottom of the vehicle body. This significantly reduces the difficulty of adjusting the de-icing device position during de-icing operations. On one hand, it shortens the preparation time required for position calibration of the air outlet unit before de-icing, thus improving de-icing efficiency. On the other hand, when the positioning component engages with the side of the vehicle body, the air outlet unit is in the de-icing position directly opposite the locking mechanism, avoiding the possibility of positional deviations between the air outlet unit and the locking mechanism caused by manual alignment, further improving the de-icing efficiency of the device.

[0072] like Figure 1 , Figure 4 , Figure 13As shown, a de-icing device is used to de-ice a battery swapping vehicle. The battery pack of the battery swapping vehicle is installed at the bottom of the vehicle body through a locking mechanism to facilitate quick battery pack swapping. The de-icing device includes a movable body 1, an air outlet unit 2 installed on the body 1, and a positioning member 3. The body 1 can move to the bottom of the vehicle body so that the air outlet unit 2 is located below the locking mechanism to blow hot air to the locking mechanism. The positioning member 3 is movably connected to the body 1 and can avoid the vehicle body when the body 1 enters the bottom of the vehicle body. After the body 1 reaches the de-icing position, it can cooperate with the side of the vehicle body so that the position of the air outlet unit 2 corresponds to the position of the locking mechanism.

[0073] Figure 13 The middle arrow Y points to the length of the battery swapping vehicle 130, and the arrow X points to the direction of movement of the de-icing device into the bottom of the battery swapping vehicle 130. The body 1 enters the bottom of the battery swapping vehicle 130 along the side of the vehicle. When de-icing the locking mechanism, the body 1 is moved to move the air outlet unit 2 to the bottom of the locking mechanism. When the air outlet unit 2 is aligned with the locking mechanism, the air outlet unit 2 sprays hot air to the locking mechanism, thereby melting the ice layer at the locking mechanism. The positioning component 3 can engage with the side of the vehicle body after the body 1 reaches the de-icing position. When the positioning component 3 engages with the vehicle body, the air outlet unit 2 reaches the de-icing position opposite the locking mechanism, thus achieving precise air supply from the air outlet unit 2 to the locking mechanism. Therefore, the operator can obtain the position of the air outlet unit 2 by observing the engagement state between the positioning component 3 and the vehicle body, eliminating the need to observe the alignment of the air outlet unit 2 and the locking mechanism from the bottom of the vehicle body. This greatly reduces the difficulty for the operator to adjust the position of the de-icing device during de-icing operations. On the one hand, it shortens the preparation time required for the position calibration of the air outlet unit 2 before de-icing, thereby improving de-icing efficiency. On the other hand, when the positioning component 3 engages with the side of the vehicle body, the air outlet unit 2 is in the de-icing position directly opposite the locking mechanism, thus avoiding the possibility of positional deviation between the air outlet unit 2 and the locking mechanism caused by manual alignment, further improving the de-icing efficiency of the de-icing device.

[0074] Preferably, the air outlet unit 2 has an air outlet located at its top, through which the air outlet unit 2 outputs hot air to the locking mechanism. The air outlet opening faces upward and is located directly below the locking mechanism when the air outlet unit 2 is in the de-icing position.

[0075] This application does not limit the connection method between the positioning component 3 and the fuselage 1, and it can adopt any of the following embodiments:

[0076] Implementation method one: such as Figures 1 to 5As shown, the positioning component 3 is rotatably connected to the body 1 and can switch between a first position and a second position to be in a corresponding horizontal or vertical state relative to the body 1. The de-icing device also includes a control mechanism connected to the positioning component 3. When the body 1 enters the bottom of the vehicle body, the control mechanism controls the positioning component 3 to switch to the first position to avoid interference with the vehicle body. When the body 1 reaches the de-icing position, the control mechanism controls the positioning component 3 to switch to the second position to abut against the side of the vehicle body.

[0077] Figure 1 The positioning component 3 is in the second position and is vertical relative to the fuselage 1. Figure 4 The positioning component 3 is in the first position and is horizontal relative to the body 1. When the body 1 is moved, the positioning component 3 is switched to the first position by the control mechanism so that the body 1 can freely enter and exit the bottom of the battery swapping vehicle, avoiding the positioning component 3 from touching the chassis or other components and affecting the movement of the body 1. When the body 1 reaches the de-icing position, the positioning component 3 is switched from the first position to the second position by the control mechanism to achieve positioning with the side of the vehicle. In this way, the operator can switch the positioning component 3 between the first and second positions by operating the control mechanism to adapt to the movement needs of the body 1 and the positioning needs of the air outlet unit 2, ensuring that the positioning component 3 can achieve the positioning function of the air outlet unit 2 while avoiding the positioning component 3 affecting the movement of the body 1.

[0078] Implementation method 2: The positioning component 3 is inserted and engaged with the body 1. The body 1 is provided with an insertion slot adapted to the positioning component 3. The positioning component 3 includes a third position that is entirely located in the insertion slot to correspond to the avoidance state of the vehicle body, and a fourth position exposed in the insertion slot to correspond to the positioning state of cooperating with the side of the vehicle body. The positioning component 3 can switch between the third position and the fourth position.

[0079] As a preferred embodiment of the following implementation method, when the positioning member 3 is in a vertical state, the highest point of the positioning member 3 is not lower than the lowest point of the side of the vehicle body.

[0080] The positioning component 3 can position the air outlet unit 2 by abutting against the side of the vehicle body. After the main body 1 is fully pushed into the bottom of the vehicle body, the operator can switch the positioning component 3 from a horizontal state to a vertical state through the control mechanism. When the positioning component 3 abuts against the side of the vehicle body, the operator will receive kinetic or auditory feedback due to the contact between the positioning component 3 and the side of the vehicle body, indicating that the positioning component 3 has cooperated with the side of the vehicle body. Alternatively, the operator can drive the main body 1 to perform a reverse movement to pull it away from the bottom of the vehicle body. If the main body 1 and the vehicle body cannot move in reverse due to the stop of the positioning component 3, If the positioning component 3 moves, it proves that the positioning component 3 has achieved cooperation with the side of the vehicle body. That is, the operator does not need to observe the cooperation status between the positioning component 3 and the vehicle body to know the cooperation status between the positioning component 3 and the vehicle body, thereby knowing the positioning status of the air outlet unit 2, reducing the difficulty of de-icing work. In addition, since the highest point of the positioning component 3 is not lower than the lowest point of the side of the vehicle body, the positioning component 3 can also play the role of blocking the airflow on the side of the vehicle body, reducing the possibility of the airflow on the side of the vehicle body or other factors interfering with the air supply of the air outlet unit 2, which helps to improve the de-icing efficiency of the de-icing device.

[0081] Preferably, the positioning member 3 has a rectangular plate structure and extends along the width direction of the fuselage 1. When the positioning member 3 is in a vertical state, its upper surface is higher than the lowest point of the side of the vehicle body.

[0082] As a preferred example in this embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the control mechanism includes a first linkage 4, a second linkage 5, and a control element 6. The first end 41 of the first linkage 4 is rotatably connected to the positioning element 3. The second end 42 of the first linkage 4 is rotatably connected to the third end 51 of the second linkage 5. The fourth end 52 of the second linkage 5 is rotatably connected to the body 1. The control element 6 is connected to the second end 42 and the third end 51 and can drive the position of the rotation point between the second end 42 and the third end 51 to change, so that the first linkage 4 and the second linkage 5 rotate, thereby enabling the positioning element 3 to switch between the first position and the second position.

[0083] The control element 6 can simultaneously act on the second end 42 of the first linkage 4 and the third end 51 of the second linkage 5, driving the first linkage 4 and the second linkage 5 to rotate synchronously, thereby enabling the positioning element 3 to switch between the first position and the second position. During this process, the first linkage 4 and the positioning element 3, the second linkage 5 and the positioning element 3, and the first linkage 4 and the second linkage 5 are all rotatably connected, thus reducing the frictional resistance that the control element 6 needs to overcome when driving the first linkage 4 and the second linkage 5 to move, making the switching of the positioning element 3 between the first position and the second position smoother. In addition, since the first linkage 4 and the second linkage 5 rotate synchronously and move closer to each other under the drive of the control element 6, the rotation speed of the positioning element 3, that is, the switching speed from the first position to the second position, is accelerated, thereby reducing the working stroke of the control element 6 when driving the positioning element 3 to switch positions, which helps to optimize the structural design of the control mechanism.

[0084] Preferably, the positioning member 3 is provided with a first rotating seat, the body 1 is provided with a second rotating seat, the first end 41 of the first linkage member 4 and the first rotating seat are respectively provided with a first rotating through hole in opposite position, the second end 42 of the first linkage member 4 and the third end 51 of the second linkage member 5 are respectively provided with a second rotating through hole in opposite position, the fourth end 52 of the second linkage member 5 and the second rotating seat are respectively provided with a third rotating through hole in opposite position, a first rotating insert shaft is inserted through the two first rotating through holes to make the first linkage member 4 rotatably connected to the first rotating seat, a second rotating insert shaft is inserted through the two second rotating through holes to make the first linkage member 4 rotatably connected to the second linkage member 5, and a third rotating insert shaft is inserted through the two third rotating through holes to make the second linkage member 5 rotatably connected to the second rotating seat; preferably, the control member is connected to the second rotating insert shaft, and the linkage line pulls the second rotating insert shaft to drive the first linkage member 4 and the second linkage member 5 to rotate simultaneously toward each other.

[0085] As a preferred method in this example, such as Figure 2 As shown, the control mechanism also includes an elastic reset member disposed between the positioning member 3 and the body 1. The elastic reset member keeps the positioning member 3 in the second position. When the control member 6 applies a force, it can overcome the force of the elastic reset member and drive the positioning member 3 to switch from the second position to the first position. When the control member 6 does not apply a force or removes the force, the force of the elastic reset member keeps the positioning member 3 in the second position or switches it from the first position to the second position.

[0086] Once the body 1 is fully pushed into the bottom of the vehicle, the operator only needs to remove the force applied to the control component 6. The positioning component 3 will then switch from the first position to the second position under the elastic action of the elastic reset component, eliminating the need for the operator to manually switch the positioning component 3 from the first position to the second position. In addition, the elastic force of the elastic reset component can also maintain the positioning component 3 in the second position. During the de-icing process of the de-icing device, the operator does not need to apply additional force to keep the positioning component 3 vertical, thus optimizing the user experience of the de-icing device.

[0087] Preferably, such as Figure 2 As shown, the elastic reset component is a spring hinge 7, which includes a first leaf 71, a second leaf 72, and a spring connecting the first leaf 71 and the second leaf 72. The positioning component 3 is fixedly connected to the first leaf 71, and the body 1 is fixedly connected to the second leaf 72. The force of the spring causes the first leaf 71 to drive the positioning component 3 to remain in the second position.

[0088] The elastic reset component is set as a spring hinge 7, and is fixedly connected to the positioning component 3 and the body 1 through the first leaf 71 and the second leaf 72 respectively. This increases the contact area between the elastic reset component and the positioning component 3 and the body 1, so that the elastic reset component can provide more stable support to the positioning component 3. The spring applies elastic force to the first leaf 71 and the second leaf 72 to maintain the included angle between the first leaf 71 and the second leaf 72, thereby maintaining the included angle between the positioning component 3 and the body 1.

[0089] Preferably, such as Figure 1 As shown, the positioning element 3 extends along the width direction of the body 1, and there are multiple spring hinges 7, which are arranged at intervals along the extension direction of the positioning element 3.

[0090] As another preferred method in this example, such as Figure 1 , Figure 4 As shown, along the length of the body 1, the body 1 has an active end 11 and a driven end 12 arranged opposite to each other. The active end 11 is driven by an applied force to move the driven end 12 from one side of the vehicle body into the bottom of the vehicle body. The positioning member 3 is disposed on the driven end 12. The active end 11 is provided with a vertically extending bearing part 13. When the body 1 moves to the bottom of the vehicle body of the battery swapping vehicle, the positioning member 3 and the bearing part 13 abut against the two sides of the vehicle body of the battery swapping vehicle respectively.

[0091] The active end 11 and the driven end 12 are respectively located on the front and rear sides of the body 1, and the bearing part 13 and the positioning part 3 are respectively located on the active end 11 and the driven end 12. On the one hand, it provides a force application position for the operator to drive the body 1. The operator can move the body 1 by applying the driving force to the bearing part 13, which reduces the difficulty of moving the body 1. In addition, the positioning part 3 and the bearing part 13 abut against the two sides of the body of the battery swapping vehicle, so that the positioning part 3 and the bearing part 13 can respectively block the airflow from the side of the body to the bottom of the body, reduce the impact of the airflow on the hot air sprayed by the air outlet unit 2, improve the heat supply stability of the air outlet unit 2 to the locking mechanism, and at the same time help reduce the diffusion of heat from the bottom of the body to the side of the body, which helps to further improve the de-icing speed of the de-icing device.

[0092] Preferably, such as Figure 1 As shown, the support unit 13 is also equipped with a handrail 19 for the operator to apply force, and the bottom of the body 1 is equipped with rollers. The operator can push and pull the body 1 into and out of the bottom of the vehicle body through the handrail 19.

[0093] As a preferred embodiment of this application, such as Figure 6 As shown, the air outlet unit 2 extends along the width direction of the body 1 and neither end of the body 1 extends beyond the positioning member 3. Figure 6 L1 represents the width of the air outlet unit 2, and L2 represents the width of the positioning component 3. L1 ≤ L2. The positioning component 3 can block the side space of the air outlet unit 2 to the greatest extent, improving the blocking effect of the positioning component 3 on airflow and debris from the side of the vehicle body, and greatly improving the stability of the hot air output of the air outlet unit 2.

[0094] As another preferred embodiment of this application, such as Figure 6 As shown, the air outlet unit 2 extends along the width direction of the body 1 and neither end of the body 1 extends beyond the support part 13 in the width direction. Figure 6 In the diagram, L1 represents the width of the air outlet unit 2, and L3 represents the width of the support portion 13, where L1 ≤ L3. The support portion 13 can provide maximum shielding for the side space of the air outlet unit 2, improving the shielding effect of the support portion 13 on airflow and debris from the side of the vehicle body, and significantly enhancing the stability of the hot air output of the air outlet unit 2.

[0095] In another preferred embodiment, the air outlet unit 2 extends along the width direction of the body 1 and neither end of the body 1 extends beyond the positioning member 3 and the supporting part 13. Thus, the two sides of the air outlet unit 2 are shielded by the positioning member 3 and the supporting part 13 respectively, effectively improving the stability of the hot air output of the air outlet unit 2.

[0096] Preferably, such as Figure 1 , Figure 4 , Figures 7 to 10 As shown, there are two of each of the first linkage 4, the second linkage 5, and the control component 6, which are symmetrically arranged at both ends of the positioning component 3 along the length of the body 1. The control mechanism also includes a synchronous shaft 8, which is connected to the end of the two control components 6 away from the rotation point of the first linkage 4 and the second linkage 5.

[0097] By setting two of the first linkage 4, the second linkage 5, and the control element 6, and placing them at both ends of the positioning element 3 respectively, the rotational force applied to the positioning element 3 is made more uniform, reducing the force required for a single control element 6 to drive the positioning element 3 to rotate. In addition, since a synchronous shaft 8 is provided, and both control elements 6 are connected to the synchronous shaft 8, the operator only needs to apply force to the synchronous shaft 8. The synchronous shaft 8 rotates and simultaneously drives the two control elements 6 to move, thereby driving the first linkage 4 and the second linkage 5 located on both sides of the positioning element 3 respectively. This eliminates the need to drive both control elements 6 to work at the same time, reduces the difficulty of the operator's work, and optimizes the structural design of the de-icing device.

[0098] Furthermore, such as Figure 9 As shown, two rotating platforms 18 are symmetrically arranged inside the fuselage 1 along the width direction of the fuselage 1. The top of the rotating platform 18 is provided with a rotating groove 181. The synchronous shaft 8 is respectively placed in the two rotating grooves 181 to support the synchronous shaft 8 and also to limit the synchronous shaft 8.

[0099] Preferably, such as Figure 9 , Figure 10 As shown, the control mechanism also includes a control lever 9 and two third linkages 10. The two third linkages 10 are arranged at both ends of the synchronous shaft 8 along the width direction of the body 1 and are respectively connected to the control components 6 at the corresponding ends. The control lever 9 is fixed to the synchronous shaft 8.

[0100] During the switching process from the second position to the first position driven by the control mechanism, the two third linkages 10 fixedly connected to the synchronous shaft 8 rotate synchronously when the synchronous shaft 8 is rotated. Since the end of the third linkage 10 away from the synchronous shaft 8 is connected to the control component 6, only a small rotation angle of the synchronous shaft 8 is needed to drive the end of the third linkage 10 away from the synchronous shaft 8 to have a large stroke, thereby achieving a large stroke change of the control component 6 connected to the third linkage 10. Subsequently, the positioning component 3 is driven to move through the first linkage 4 and the second linkage 5. That is, the positioning component 3 can be switched from the second position to the first position with a small rotation of the synchronous shaft 8, which reduces the working space required for the control mechanism to drive the positioning component 3 to move, and helps the de-icing device. The miniaturization of the device allows the operator to move the positioning component 3 to the first position with only a small force stroke, thus optimizing the structural design of the de-icing device. Furthermore, since the rotation trajectory of the synchronous shaft 8 is fixed, the synchronous rotation trajectory of the third linkage 10 as it rotates with the synchronous shaft 8 is also fixed. This ensures that the movement trajectory of the control component 6 connected to the third linkage 10 is constant. Therefore, by rotating the synchronous shaft 8, the two control components 6 can move along a fixed trajectory to move the positioning component 3 from the second position to the first position. This avoids the phenomenon of force deviation of the control component 6 on the first linkage 4 and the second linkage 5 caused by operator force deviation or other factors, thus ensuring the stability of the positioning component 3 during the switching process from the second position to the first position.

[0101] Furthermore, such as Figure 9 As shown, the third linkage 10 has a connecting through hole 101 at the end away from the synchronous shaft 8, and the control component 6 is connected to the third linkage 10 through the connecting through hole 101.

[0102] Preferably, such as Figure 7 , Figure 9 , Figure 12 As shown, the control component 6 is a rope. A fixed pulley 14 is provided on the machine body 1 at the active end 11, and a limiting shaft 15 is provided at the driven end 12. The rope is led out from the third linkage 10, wound around the fixed pulley 14, and extends to the driven end 12. It passes through the through hole 151 on the limiting shaft 15 and connects with the second end 42 and the third end 51. Preferably, the machine body 1 is also provided with a plurality of threading pipes 16 located between the fixed pulley 14 and the limiting shaft 15 and spaced apart. The threading pipes 16 are hollow inside to form a threading channel 161 for the rope to pass through.

[0103] By designing the control element 6 as a rope, its extension direction can be adjusted according to the structural layout of the de-icing device, significantly improving its adaptability to the device's structure. Furthermore, by installing a fixed pulley 14 at the active end 11, the control element 6, after being led out from the third linkage 10, smoothly rotates its extension direction towards the driven end 12. When the control element 6 moves under the influence of the third linkage 10, there is rolling friction between it and the fixed pulley 14. This reduces the frictional force on the control element 6, decreasing wear and tear, and also reducing the force required to move it via the third linkage 10. This allows the operator to more easily drive the first linkage 4 via the control element 6. The second linkage 5 moves; in addition, by setting a limiting shaft 15 at the driven end 12, the extension direction of the control member 6 toward the first linkage 4 and the second linkage 5 can be adjusted by the extension direction of the through hole 151 in the limiting shaft 15, thereby adjusting the force angle of the control member 6 on the second end 42 and the third end 51, and further optimizing the driving effect of the control member 6 on the positioning member 3; furthermore, the multiple wire-passing pipes 16 set on the side of the body 1, and the wire-passing channel 161 formed by the cooperation of the multiple wire-passing pipes 16, play a fixed guiding role for the extension of the control member 6 at the active end 11 and the driven end 12, so that the control member 6 extends and retracts along the extension direction of the wire-passing channel 161 under the drive of the third linkage 10, thereby preventing the control member 6 from shifting.

[0104] Furthermore, the control component 6 may be made of steel wire rope, nylon rope, or other materials.

[0105] Preferably, such as Figure 10 , Figure 11 As shown, along the width direction of the body 1, a rotating seat 17 is provided on one side of the bearing part 13. The rotating seat 17 has an opening 171 on the side away from the driven end 12. When the control lever 9 rotates from its original position where it is disengaged from the rotating seat 17 to a mating position where it mates with the rotating seat 17 in the opening 171, the positioning member 3 switches from the second position to the first position.

[0106] Before moving the body 1 to the bottom of the vehicle body, first rotate the control lever 9 to the position that engages with the rotating seat 17. At this time, the positioning component 3 switches from the second position to the first position, that is, it is in a horizontal state. At this time, the body 1 can be moved to the bottom of the vehicle body. After the body 1 has completely moved to the bottom of the vehicle body, release the engagement between the rotating lever and the rotating seat 17, and rotate the control lever 9 back to the original position. At this time, the positioning component 3 switches from the first position to the second position and engages with the side of the vehicle body to position the body 1, thereby locking the air outlet unit 2 in the de-icing position.

[0107] Preferably, such as Figure 10 , Figure 11As shown, the control lever 9 includes a first lever 91 and a second lever 92 connected together. The first lever 91 is located above the second lever 92, and the diameter of the first lever 91 is larger than the diameter of the second lever 92 to form a boss surface at the connection between the first lever 91 and the second lever 92. The diameter of the opening 171 is smaller than that of the first lever 91 and larger than that of the second lever 92. Vertically upward baffles 172 are provided on both sides of the opening 171. The gap between the two baffles 172 is equal to the diameter of the opening 171. When the control lever 9 is in the mating position, the boss surface mates with the bearing surfaces on both sides of the opening 171, and the baffles 172 can restrict the first lever 91 to prevent the control lever 9 from disengaging from the rotating seat 17.

[0108] During the transfer of control lever 9 from its original position to its initial position, the second lever 92 is aligned with opening 171 and control lever 9 is rotated to the mating position through opening 171. Then, the first lever 91 is aligned with opening 171. At this time, the first lever 91 is restricted within the rotating seat 17 by the stop action of the two baffles 172, thereby temporarily fixing control lever 9 to rotating seat 17, so that positioning member 3 is in the first position. In this way, when pushing the machine body 1 into the bottom of the vehicle body, control lever 9 locks positioning member 3 in the first position under the limiting action of rotating seat 17. The operator does not need to apply additional control force to control lever 9 to maintain the horizontal state of positioning member 3, so that all attention can be focused on pushing the machine body 1 to move, which helps to improve the stability of the movement of machine body 1. In addition, when the machine body 1 has completely moved to the bottom of the vehicle body, control lever 9 is adjusted until the second lever 92 is aligned with opening 171, and control lever 9 is rotated from the mating position to the original position through opening 171. At this time, positioning member 3 switches from the first position to the second position to mate with the side of the vehicle body.

[0109] Specifically, the de-icing device operates as follows: After the battery swapping vehicle arrives, the de-icing device is positioned on one side of the vehicle. At this time, the positioning component 3 is in the second position under the maintenance of the elastic reset component, and the control lever 9 is in its original position. The operator pulls the control lever 9 to rotate towards the rotating seat 17. Driven by the control lever 9, the synchronous shaft 8 rotates in the rotating groove 181 and synchronously drives the two third linkage components 10 to rotate. The control component 6 is tightened as the third linkage component 10 rotates, and by pulling the second end 42 and the third end 51, the rotation point is displaced towards the direction of the control lever 9 (or, towards the direction of the active end 11 of the body 1), causing the first linkage component 4 and the second linkage component 5 to rotate towards each other, thereby realizing the switching of the positioning component 3 from the second position to the first position. When the control lever 9 rotates... After the rotating seat 17 is moved, the baffle 172 fixes the control rod 9 inside the rotating seat 17 by stopping the first rod 91, so as to maintain the positioning member 3 in the first position; the operator pushes the body 1, and the driven end 12 enters the bottom of the body from the side of the battery swapping vehicle until the body 1 reaches the de-icing position. At this time, the bearing part 13 abuts against the side of the body. The operator pulls the control rod 9 upward until the second rod 92 is opposite to the opening 171, and then rotates the control rod 9 in the opposite direction. The control rod 9 rotates in the opposite direction to drive the third linkage 10 to rotate with the synchronous shaft 8, and then the pulling force applied to the control member 6 is removed. The positioning member 3 moves to the second position under the action of the elastic reset member. The operator adjusts the body 1 by pulling back or other means until the positioning member 3 cooperates with the side of the body. Then the air outlet unit 2 is positioned in the de-icing position.

[0110] As a preferred embodiment of this application, such as Figure 1 As shown, a heating unit 110 is provided inside the bearing part 13, and the heating unit 110 provides hot air to the air outlet unit 2 through the transmission pipe.

[0111] By placing the heating unit 110 inside the support portion 13, the support portion 13 not only serves to cooperate with the side of the vehicle body to achieve multiple positioning of the air outlet unit 2 and to provide a wind deflector, but also further integrates the function of providing an installation position for the heating unit 110. This further integrates the functions and optimizes the structural design of the de-icing device. In addition, placing the heating unit 110 inside the support portion 13 achieves a concealed layout of the heating unit 110, reducing the area of ​​the heating unit 110 exposed on the outside of the de-icing device and reducing the probability that ice water sliding off the locking mechanism will affect the heating unit 110.

[0112] Preferably, the heating unit 110 can be a diesel heater.

[0113] As a preferred embodiment of this application, such as Figure 2 , Figure 5As shown, the positioning component 3 has a flexible anti-collision pad 120 on the side facing the vehicle body. With the flexible anti-collision pad 120 on the side of the positioning component 3 facing the vehicle body, when the positioning component 3 switches from the first position to the second position, the flexible anti-collision pad 120 can absorb the impact force between the positioning component 3 and the side of the vehicle body caused by the rotation of the positioning component 3, reducing the kinetic energy impact on the side of the vehicle body and the positioning component 3, ensuring the structural strength of the positioning component 3, and preventing scratches caused by the positioning component 3 contacting the side of the vehicle body.

[0114] As another preferred embodiment of this application, such as Figure 2 , Figure 5 As shown, a flexible anti-collision pad 120 is provided on the side of the load-bearing part 13 facing the side of the vehicle body. When the load-bearing part 13 comes into contact with the side of the vehicle body, the flexible anti-collision pad 120 can absorb the impact force brought about by the interaction between the two parts and can prevent the scraping caused by the contact between the load-bearing part 13 and the side of the vehicle body.

[0115] In other preferred embodiments, both the positioning member 3 and the bearing part 13 are provided with flexible anti-collision pads 120 on the side facing the vehicle body, so that both sides of the vehicle body of the battery swapping vehicle are protected.

[0116] Preferably, the flexible anti-collision pad can be made of sponge, rubber or other materials.
