Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to a vehicle charging port assembly, a control method applicable to the vehicle charging port assembly, and a vehicle having the vehicle charging port assembly. Background Technology

[0002] As vehicles continue to develop and technological innovations advance rapidly, vehicle safety performance remains a key focus and of paramount importance.

[0003] Vehicle fires have always been a major concern, especially those occurring while charging or driving. In real-world scenarios, at a charging station, when a row of vehicles are charging, if one of them catches fire, the fire can spread rapidly, reach high temperatures, and produce intense flames. If nearby vehicles are not moved away in time, the fire can spread to other innocent vehicles, causing damage, and in some cases, multiple vehicles may even burn simultaneously.

[0004] In related technologies, vehicles can autonomously identify surrounding fire sources and drive away from them. However, when a vehicle identifies a fire source and drives away while charging, the charging module and charging gun are connected and mechanically / electronically locked, requiring manual separation. Without separation, the vehicle's departure can damage the charging module and charging gun. Furthermore, forcibly driving away while the vehicle is charging and still powered on poses significant safety risks. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vehicle charging port assembly that not only ensures the normal charging function of the vehicle, but also reliably separates the vehicle charging structure from the external charging gun in the event of a fire, ensuring that the vehicle can safely drive out of the danger zone without damaging the charging structure. This effectively protects both the charging gun and the vehicle charging structure, thus guaranteeing vehicle safety.

[0006] According to an embodiment of the present invention, a vehicle charging port assembly includes: a female charging terminal and a male charging terminal, the female charging terminal being connected to the vehicle body, the female charging terminal and the male charging terminal being detachably connected via a connecting assembly, and a charging gun being adapted to pass through the male charging terminal for plugging into the female charging terminal; a disassembly structure for disassembling the connecting assembly to separate the female charging terminal from the male charging terminal; an elastic member and an electromagnetic drive assembly, the elastic member being elastically pressed between the female charging terminal and the male charging terminal and being used to apply an elastic thrust away from the female charging terminal to the male charging terminal; the electromagnetic drive assembly being used to apply a magnetic attraction force to bring the female charging terminal and the male charging terminal closer to each other during the disassembly of the connecting assembly, and to apply a magnetic repulsion force to move the female charging terminal and the male charging terminal away from each other after the disassembly of the connecting assembly is completed.

After the disassembly process of the connecting component is completed, the male charging terminal can be ejected by the combined action of the elastic thrust applied by the elastic element and the magnetic repulsion applied by the electromagnetic drive component, thereby separating the vehicle charging structure from the external charging gun, ensuring that the vehicle can safely drive out of the danger zone without damaging the charging structure, realizing the protection of the charging gun and the vehicle charging structure, and ensuring the safety of the vehicle.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] The following is for reference. Figures 1-7The vehicle charging port assembly 100 according to an embodiment of the present invention can ensure the normal charging function of the vehicle, and in the event of a fire in the surrounding area, it can also reliably separate the vehicle charging structure from the external charging gun 200, ensuring that the vehicle can safely drive out of the danger zone without damaging the charging structure, thus achieving effective protection of the charging gun 200 and the vehicle charging structure, and ensuring the safety of the vehicle.

[0027] like Figures 1-7 As shown, a vehicle charging port assembly 100 according to an embodiment of the present invention includes: a charging female terminal 1, a charging male terminal 2, a disassembly structure 3, an elastic element 4, and an electromagnetic drive assembly 5.

[0028] The female charging terminal 1 and the male charging terminal 2 are connected to the vehicle body 300. The female charging terminal 1 and the male charging terminal 2 are detachably connected through the connecting component 6. The charging gun 200 is adapted to be inserted through the male charging terminal 2 to be connected to the female charging terminal 1.

[0029] Specifically, the female charging terminal 1 and the male charging terminal 2 are located at the vehicle's charging port. The female charging terminal 1 is connected to the inner wall of the charging port via bolts, screws, rivets, or other connectors to securely attach the female charging terminal 1 to the vehicle body 300. The female charging terminal 1 is connected to the charging harness inside the vehicle to charge the power battery. The male charging terminal 2 is located outside the female charging terminal 1, meaning that the male charging terminal 2 and the female charging terminal 1 are connected along the vehicle's interior / exterior direction or other directions. The female charging terminal 1 and the male charging terminal 2 can be detachably connected via a connecting component 6. The connecting component 6 can be configured as a snap-fit ​​and slot, bolt and nut, stud and nut, hook and hole, protrusion and hole, etc., meaning the female charging terminal 1 can be snap-fitted, threaded, or connected to the male charging terminal 2 in other ways, allowing for detachable connection and disassembly of the female charging terminal 1 and the male charging terminal 2. When actually charging a vehicle, the charging gun 200 at the external charging station needs to pass through the male charging terminal 2 from the outside in to insert into the female charging terminal 1 and connect with it, thus establishing an electrical connection between the charging gun 200 and the female charging terminal 1, thereby enabling vehicle charging. It should be noted that the female charging terminal 1 has a groove adapted to the charging gun 200, and the male charging terminal 2 has a hole or cavity adapted to the charging gun 200. The hole or cavity and the groove are connected after the female charging terminal 1 and the male charging terminal 2 are connected, allowing the charging gun 200 to smoothly pass through the male charging terminal 2 and connect with the female charging terminal 1.

[0030] The vehicle charging port assembly 100 also includes a disassembly structure 3. The disassembly structure 3 is used to disassemble the connecting component 6 to separate the charging female terminal 1 from the charging male terminal 2. That is, when a fire occurs around the vehicle, the disassembly structure 3 can disassemble the connecting component 6 to release the constraint connection between the connecting component 6 and the charging female terminal 1 and the charging male terminal 2, so that both the charging female terminal 1 and the charging male terminal 2 are in a free state, thereby realizing the separation of the connection between the charging female terminal 1 and the charging male terminal 2, that is, the charging male terminal 2 can be separated from the charging female terminal 1.

[0031] The vehicle charging port assembly 100 also includes an elastic element 4 and an electromagnetic drive assembly 5. The elastic element 4 is elastically pressed between the charging female terminal 1 and the charging male terminal 2 and is used to apply an elastic thrust away from the charging female terminal 1 to the charging male terminal 2. The electromagnetic drive assembly 5 is used to apply a magnetic attraction force to bring the charging female terminal 1 and the charging male terminal 2 closer to each other during the disassembly of the connecting assembly 6, and to apply a magnetic repulsion force to move the charging female terminal 1 and the charging male terminal 2 away from each other after the disassembly of the connecting assembly 6 is completed.

[0032] Specifically, the elastic element 4 is elastic and undergoes elastic deformation when subjected to external force to generate an elastic force that restores it to its initial state. When the electromagnetic drive assembly 5 is energized, it generates an electromagnetic force as current flows through it. The direction of the current can be controlled to make the electromagnetic drive assembly 5 generate a magnetic attraction force that brings the charging female terminal 1 and the charging male terminal 2 closer together, or a magnetic repulsion force that moves them away from each other. For example, a forward current can be used to generate a magnetic attraction force, and a reverse current can be used to generate a magnetic repulsion force.

[0033] When the vehicle is in normal charging state, the female charging terminal 1 and the male charging terminal 2 are connected through the connecting component 6, and the outer end face of the female charging terminal 1 near the male charging terminal 2 is opposite to the outer end face of the male charging terminal 2 near the female charging terminal 1. One end of the elastic member 4 is elastically pressed against the female charging terminal 1, and the other end of the elastic member 4 is elastically pressed against the male charging terminal 2. At this time, the elastic member 4 is compressed by the female charging terminal 1 and the male charging terminal 2, generating an elastic thrust, which is directed towards the male charging terminal 2.

[0034] When the vehicle is charging and a fire occurs nearby, the disassembly structure 3 begins operation. Disassembly structure 3 disassembles the connecting assembly 6. During disassembly, the electromagnetic drive assembly 5 is energized, generating a magnetic attraction force to keep the elastic element 4 in a state of maximum compression, producing a large elastic thrust. This prevents relative movement between the charging female terminal 1 and the charging male terminal 2 during disassembly, reducing the compressive elastic force of the elastic element 4 and thus reducing the elastic thrust on the charging male terminal 2. After the disassembly of the connecting assembly 6 is complete, i.e., after the charging female terminal 1 and the charging male terminal 2 are separated, the current direction of the electromagnetic drive assembly 5 can be changed, abruptly changing from generating a magnetic attraction force to generating a magnetic repulsion force. At this point, under the combined action of the elastic thrust and the charging male terminal 2, the charging male terminal 2 can move away from the charging female terminal 1, i.e., outwards from the vehicle, thus achieving the ejection function of the charging male terminal 2. Since the male charging terminal 2 is connected to the charging gun 200, when the male charging terminal 2 is ejected, it will move the charging gun 200 together in a direction away from the female charging terminal 1, thereby realizing the automatic separation of the charging gun 200 from the vehicle charging port, ending the vehicle charging, without causing damage to the charging gun 200 and the charging port, thus allowing the vehicle to drive away safely, ensuring the safety of the vehicle in the event of spontaneous combustion of surrounding vehicles, and protecting the user's property safety.

[0035] According to an embodiment of the present invention, the vehicle charging port assembly 100 is configured as a split type, namely, a female charging terminal 1 connected to the vehicle body 300 and a male charging terminal 2 detachably connected to the female charging terminal 1 via a connecting component 6. The charging gun 200 can be inserted through the male charging terminal 2 to connect with the female charging terminal 1, ensuring the normal charging function of the vehicle. At the same time, in the event of a fire in the vicinity, the disassembly structure 3 can disassemble the connecting component 6. During the disassembly process, the electromagnetic drive component 5 can apply a magnetic attraction force to prevent the female charging terminal 1 and the male charging terminal 2 from moving relative to each other during the disassembly process, so that the elastic member 4 can be kept in the maximum compression state. After the disassembly process of the connecting component 6 is completed, the male charging terminal 2 can be ejected under the combined action of the elastic thrust applied by the elastic member 4 and the magnetic repulsion applied by the electromagnetic drive component 5, thereby separating the vehicle charging structure from the external charging gun 200. This ensures that the vehicle can safely drive out of the danger zone without damaging the charging structure, thus protecting the charging gun 200 and the vehicle charging structure and ensuring the safety of the vehicle.

[0036] In some embodiments, the connecting component 6 includes a first connector 61 and a second connector 62. The first connector 61 is sequentially disposed on the male charging terminal 2 and the female charging terminal 1. The second connector 62 is sleeved on the outside of the first connector 61 and threadedly connected to the first connector 61. The second connector 62 is adapted to press against the inner wall of the female charging terminal 1 on the side near the male charging terminal 2.

[0037] Specifically, see the attached document. Figure 1 and attached Figure 2 As shown, a first connection hole can be provided on the male charging terminal 2 and a second connection hole can be provided on the female charging terminal 1. The shape and size of the first connection hole and the second connection hole match the shape and size of the first connector 61 and their positions correspond, so that the first connector 61 can be sequentially inserted into the first connection hole and the second connection hole to realize the connection between the male charging terminal 2 and the female charging terminal 1. Furthermore, an external thread can be provided on the outer peripheral wall of the first connector 61, and a through hole with an internal thread can be provided on the second connector 62. In this way, the second connector 62 can be sleeved on the outside of the first connector 61 and achieve a threaded connection with the first connector 61 through the mutual engagement of the internal and external threads. This allows the second connector 62 to move linearly along the length direction of the first connector 61. During the movement of the second connector 62 towards the inner wall of the side near the male charging terminal 2, the elastic element 4 is continuously compressed, and the compression amount gradually increases, and the elastic compression force gradually increases. That is, the elastic thrust applied to the male charging terminal 2 gradually increases until the second connector 62 rotates along the length direction of the first connector 61 and presses against the inner wall of the side near the male charging terminal 2 of the female charging terminal 1, thereby achieving the fastening of the first connector 61. This achieves a fixed connection between the female charging terminal 1 and the male charging terminal 2, preventing loosening or shaking between the female charging terminal 1 and the male charging terminal 2. At the same time, the elastic compression force reaches its maximum.

[0038] It should be noted that the magnitude of magnetic attraction and repulsion can be adjusted by controlling the current flowing through the electromagnetic drive component 5. The elastic element 4 can be constructed as a spring, and the magnitude of the elastic thrust can be adjusted by controlling the K value (stiffness coefficient) of the spring, thereby ensuring that the charging male terminal 2 can be smoothly ejected relative to the charging female terminal 1, and ensuring the reliability of the ejection function of the charging male terminal 2.

[0039] In actual design, the first connector 61 can be constructed as a connecting bolt, and the second connector 62 can be constructed as a connecting nut.

[0040] In some embodiments, the disassembly structure 3 includes a drive member 31 and a transmission gear 32. The drive member 31 is connected to the transmission gear 32 in a transmission manner. The transmission gear 32 meshes with the second connector 62 in a transmission manner. The drive member 31 is adapted to drive the transmission gear 32 to move the second connector 62 along the axial direction of the first connector 61 toward a direction away from the charging male terminal 2, so that the second connector 62 disengages from the first connector 61.

[0041] Specifically, the driving component 31 is a power source that provides power to the second connecting component 62, enabling the second connecting component 62 to be separated from the first connecting component 61, thus facilitating the disassembly of the connecting assembly 6. The driving component 31 and the transmission gear 32 can be connected via a reduction mechanism, allowing the driving component 31 to transmit power to the transmission gear 32, causing the transmission gear 32 to rotate. Simultaneously, the reduction mechanism prevents the transmission gear 32 from moving unevenly. Furthermore, since the transmission gear 32 meshes with the second connecting component 62 (i.e., the outer circumference of the second connecting component 62 has teeth that mesh with the transmission gear 32), the rotation of the transmission gear 32 can drive the second connecting component 62 to rotate, thereby connecting or separating the second connecting component 62 from the first connecting component 61.

[0042] Therefore, the connection component 6 can be automatically disassembled by disassembling structure 3 to release the connection constraint between the charging male terminal 2 and the charging female terminal 1. This is flexible and convenient, requires no manual disassembly, and has high reliability.

[0043] In practical design, the drive component 31 can be configured as a drive motor, such as a DC motor, AC motor, stepper motor, servo motor, speed-regulating motor, etc., which can be flexibly configured according to actual needs. The transmission gear 32 can be constructed as a first bevel gear, and the second connecting component 62 can be constructed as a second bevel gear that matches the bevel gear. The second bevel gear is sleeved on the outside of the first connecting component 61 and threadedly connected to the first connecting component 61. The axis of the first bevel gear is fixed and intersects perpendicularly with the axis of the second bevel gear. The axis of the second bevel gear is the axis of the first connecting component 61. In this way, it can be ensured that the transmission gear 32 continuously drives the second connecting component 62 to rotate and move axially, and the two mesh continuously.

[0044] In some embodiments, the effective tooth width of the transmission gear 32 is D1, the distance from the connection position to the disengagement position of the second connector 62 is D0, and the following conditions are met: D0 < D1.

[0045] Specifically, the effective tooth width D1 of the transmission gear 32 is the effective meshing radial width between the transmission gear 32 and the second connector 62, and the distance D0 of the second connector 62 from the connection position to the disengagement position is the distance between the end face of the second connector 62 near the charging female end 1 and the position just away from the end of the first connector 61 away from the charging male end 2.

[0046] Therefore, by setting the effective tooth width D1 of the transmission gear 32 to be greater than the distance D0 from the connection position to the disengagement position of the second connector 62, it can be ensured that the teeth of the second connector 62 are always engaged with the teeth of the transmission gear 32 during the movement, and will not disengage. In other words, the meshing point between the transmission gear 32 and the second connector 62 moves radially on the tooth surface of the transmission gear 32, and the radial span corresponding to the maximum axial movement distance of the second connector 62 always falls within the effective gear range of the transmission gear 32. This ensures that the transmission gear 32 stably drives the second connector 62 to disengage, thus ensuring the effective separation of the second connector 62 from the first connector 61. This prevents the second connector 62 from getting stuck on the first connector during the movement and being unable to disengage, thus preventing the effective disassembly of the connecting component 6 and causing the charging male terminal 2 to be unable to separate from the charging female terminal 1.

[0047] When the transmission gear 32 is constructed as a first bevel gear and the second connecting member 62 is constructed as a second bevel gear that matches the bevel gear, the above arrangement allows the meshing point to continuously change along the conical surface of the bevel teeth, and the tooth surfaces always fit together and will not disengage. That is, within the entire stroke range of the second bevel gear, when the second bevel gear moves back and forth along its own axis, the meshing point moves radially along the generatrix of the cone on the conical surface of the first bevel gear, and the tooth surfaces of the two gears always remain in contact and meshing.

[0048] In a specific embodiment, such as Figure 3 As shown, the distance from the connection position to the disengagement position of the second connector 62 is D0. As shown in the left-right direction of the figure, when the second connector 62 is in the connection position, its right end face is pressed against the right inner wall of the charging female terminal 1. When the second connector 62 is in the disengagement position, its right end face overlaps with the left end of the first connector 61, meaning the second connector 62 and the first connector 61 have just separated. The overall gear of the transmission gear 32 is greater than the maximum stroke of the second connector 62, i.e., D0. The driving member 31 can rotate clockwise to drive the second connector 62 to move to the left. The second connector 62 moves until the left end of the first connector 61 disengages, i.e., it moves to the disengagement position and disengages, thus eliminating the connection constraint between the charging male terminal 2 and the charging female terminal 1. The driving member 31 can also rotate counterclockwise to drive the second connector 62 to move to the right and back to the connection position, so that the charging male terminal 2 and the charging female terminal 1 are fixedly connected.

[0049] In some embodiments, such as Figures 1-3 As shown, the first connector 61 is constructed as a bolt, which includes a bolt head 611 and a bolt shank 612. The bolt shank 612 is sequentially inserted through the charging male terminal 2 and the charging female terminal 1 to be threadedly connected to the second connector 62. The bolt can be configured as a hexagonal head bolt, that is, the bolt head 611 is hexagonal.

[0050] Among them, such as Figure 4As shown, the charging male terminal 2 is provided with an anti-rotation groove 21. The anti-rotation groove 21 can be set as a hexagonal groove that matches the bolt head 611. In this way, the bolt head 611 can be installed in the anti-rotation groove 21, so that the outer peripheral wall of the bolt head 611 can abut against the inner peripheral wall of the anti-rotation groove 21, thereby realizing the circumferential limiting fit between the bolt head 611 and the anti-rotation groove 21. This achieves circumferential fixation of the bolt and prevents the first connecting member 61 from rotating when the driving member 31 drives the second connecting member 62 to move axially along the first connecting member 61, thus ensuring the smooth disengagement of the second connecting member 62.

[0051] In some embodiments, the electromagnetic drive assembly 5 includes a first magnetic element 51 and a second magnetic element 52. One of the charging female terminal 1 and the charging male terminal 2 is provided with the first magnetic element 51 and the other is provided with the second magnetic element 52. A magnetic attraction force or a magnetic repulsion force is formed between the first magnetic element 51 and the second magnetic element 52.

[0052] In other words, the first magnetic component 51 can be disposed on the charging female terminal 1, and the second magnetic component 52 can be disposed on the charging male terminal 2, or the first magnetic component 51 can be disposed on the charging male terminal 2, and the second magnetic component 52 can be disposed on the charging female terminal 1. The first magnetic component 51 is constructed as a coil, and the second magnetic component 52 can be constructed as a magnet. After the coil is energized, based on the magnetic effect of the current, the current passing through the coil generates a magnetic field, which is superimposed on the magnetic field of the magnet to generate an electromagnetic force. If a positive current passes through the coil, the end of the coil near the magnet has opposite poles to the magnet (the coil end is the N pole, and the magnet end is the S pole). Opposite poles attract each other, thus generating a magnetic attraction force between the coil and the magnet, which can attract the charging female terminal 1 and the charging male terminal 2 to each other. However, when a reverse current passes through the coil, the end of the coil near the magnet has the same poles as the magnet (the coil end is the S pole, and the magnet end is the S pole). Like poles repel each other, thus generating a magnetic repulsion force between the coil and the magnet. Alternatively, the magnet can be set as the N pole. When the coil is energized in the forward direction, it attracts the magnet, and when it is reversed and becomes the N pole, it repels the magnet. The principle is the same, and it can be set flexibly.

[0053] Therefore, the electromagnetic drive component 5 can generate electromagnetic forces in different directions simply by changing the direction of the current, achieving bidirectional control without the need for other complex mechanical control structures. This helps reduce the number of parts, improves the integration and lightweighting of the vehicle charging port assembly 100, and provides flexible, high-precision, and rapid control.

[0054] In some embodiments, such as Figure 2As shown, the elastic element 4 can be constructed as a highly elastic helical spring. The helical spring is sleeved outside the first connecting member 61, that is, the first elastic element 4 is sleeved outside the connecting assembly 6. One end of the elastic element 4 presses against the outer end face of the charging female terminal 1 and the other end presses against the outer end face of the charging female terminal 1. When connecting the charging male terminal 2 and the charging female terminal 1, the helical spring will be squeezed by the outer end face of the charging female terminal 1 and the outer end face of the charging female terminal 1 to generate a compressive elastic force.

[0055] In actual setup, multiple elastic elements 4 can be set to press against the charging male terminal 2 and the charging female terminal 1, so that the charging male terminal 2 can be separated from the charging female terminal 1 by the elastic thrust applied by multiple elastic elements 4. When one of the elastic elements 4 fails or is damaged, the other elastic elements 4 can still work normally, which improves the ejection reliability and stability of the charging male terminal 2.

[0056] In some other embodiments, one of the charging female terminal 1 and the charging male terminal 2 is provided with a positioning boss 22 and the other is provided with a positioning hole 11, and the positioning boss 22 and the positioning hole 11 are positioned and engaged.

[0057] In other words, a positioning boss 22 can be provided on the female charging terminal 1, and a positioning hole 11 can be provided on the male charging terminal 2; or, a positioning hole 11 can be provided on the female charging terminal 1, and a positioning boss 22 can be provided on the male charging terminal 2. The positioning boss 22 is adapted to the positioning hole 11, and the positioning boss 22 can be inserted into the positioning hole 11 along the connection direction of the female charging terminal 1 and the male charging terminal 2 to achieve positioning cooperation between the positioning boss 22 and the positioning hole 11. This achieves precise positioning of the connection position of the male charging terminal 2 and the female charging terminal 1, which can improve the connection convenience of the male charging terminal 2 and the female charging terminal 1.

[0058] In a specific embodiment, such as Figure 1 As shown, the female charging terminal 1 is provided with a positioning hole 11. The positioning hole 11 can be located on the outer end face of the female charging terminal 1 near the male charging terminal 2 and is open towards the male charging terminal 2. The male charging terminal 2 is provided with a positioning boss 22. The positioning boss 22 can be located on the outer end face of the male charging terminal 2 near the female charging terminal 1 and extends towards the female charging terminal 1. Thus, the positioning boss 22 can move smoothly to the left to insert into the positioning hole 11, realizing the insertion and positioning engagement. In actual design, the positioning hole 11 can be set as a circular hole, and the positioning boss 22 can be set as a corresponding cylindrical shape. Of course, it can also be set as other shapes, such as the positioning boss 22 can also be set as a cone shape, which can achieve a certain guiding function and can be flexibly set, not limited to the one described in this embodiment.

[0059] In other embodiments, the magnetic attraction force of the electromagnetic drive component 5 is greater than the elastic thrust of the elastic element 4.

[0060] Therefore, it can be ensured that the relative positions of the charging male terminal 2 and the charging female terminal 1 remain stable during the movement of the second connector 62 from the connected position to the detached position, that is, the two will not move relative to each other, thus ensuring that the elastic element 4 between the charging male terminal 2 and the charging female terminal 1 remains in a state of maximum compression. It should be noted that the maximum compression state of the elastic element 4 here refers to the maximum degree of compression that the elastic element 4 can achieve without damage. The magnetic attraction force should be slightly greater than the elastic thrust of the elastic element 4 to avoid excessive compression and damage to the elastic element 4.

[0061] In some embodiments, refer to the appendix Figure 1 As shown, the outer peripheral wall of the male charging terminal 2 is provided with a guide post 23, which can extend radially outward. The vehicle body 300 is provided with a guide groove 301 extending along the connection direction between the female charging terminal 1 and the male charging terminal 2. The guide post 23 matches the guide groove 301. The guide post 23 can extend into the guide groove 301 along the connection direction between the female charging terminal 1 and the male charging terminal 2, so that the outer wall of the guide post 23 abuts against the inner wall of the guide groove 301 and can slide along the guide groove 301, thereby realizing the guiding sliding cooperation between the guide post 23 and the guide groove 301.

[0062] The male charging terminal 2 is adapted to slide along the guide groove 301 via the guide post 23 and move away from the female charging terminal 1. That is, when the male charging terminal 2 is ejected by force, the male charging terminal 2 can be guided by the guide post 23 sliding along the guide groove 301, so that the male charging terminal 2 can move stably in the direction away from the female charging terminal 1, thus ensuring the stability of the movement of the male charging terminal 2.

[0063] In practical design, such as Figure 5 As shown, a guide groove 301 can be provided on the inner wall of the charging port recess of the vehicle. The guide groove 301 can be constructed as a rectangular groove. The guide groove 301 has an opening 3011. The guide post 23 can include a sliding part 231 and a connecting part 232 connected together. The width of the sliding part 231 is greater than the width of the connecting part 232. The size of the sliding part 231 matches the rectangular groove (guide groove 301). The size of the connecting part 232 matches the opening 3011. The opening 3011 can be set to be slightly larger than the width of the opening 3011. Thus, the guide post 23 can be constructed as a T-shape. The connecting part 232 can pass through the opening 3011 so that the sliding part 231 extends into the rectangular groove. Then, the outer wall of the sliding part 231 can fit against the inner wall of the rectangular groove. The sliding part 231 can slide stably along the inner wall of the rectangular groove. To improve sliding efficiency and reduce sliding resistance between guide post 23 and guide groove 301, grease can be added to the inner wall of guide groove 301 and the outer wall of sliding post. That is, grease is added at the contact position between guide groove 301 and sliding post to reduce the resistance generated by friction between the two.

[0064] Understandably, the T-shaped guide post 23 can also effectively prevent the guide post 23 from coming out of the sliding groove, thus achieving a certain limiting and anti-detachment function, such as... Figure 5 As shown in the vertical direction, the bottom wall of the guide groove 301 is close to the vehicle body 300, and the top wall of the guide groove 301 is provided with an opening 3011. The top wall of the guide groove 301 can be limited and pressed against the side end face of the sliding part 231 and the connecting part 232 to prevent the guide post 23 from coming out of the guide groove 301 when the charging male terminal 2 is ejected.

[0065] In other embodiments, the female charging terminal 1 is provided with a plurality of pin contacts 12, which are adapted to be inserted into the male charging terminal 2. The charging gun 200 is provided with a plurality of socket contacts, which are adapted to be inserted and engaged with the plurality of pin contacts 12 in a one-to-one correspondence.

[0066] Specifically, such as Figure 1 As shown, the female charging terminal 1 may have two, three, four, or more pin contacts 12. The pin contacts 12 extend along the connection direction between the female charging terminal 1 and the male charging terminal 2, that is, the insertion direction of the charging gun 200. One end of the pin contact 12 is connected to the wiring harness in the vehicle, and the other end of the pin contact 12 passes through the male charging terminal 2. The charging gun 200 is provided with multiple socket contacts that match the pin contacts 12. That is, the number of pin contacts 12 and socket contacts is the same. In this way, after the charging gun 200 passes through the male charging terminal 2 and extends into the female charging terminal 1, each pin contact 12 can be inserted into the corresponding socket contact to realize the one-to-one insertion and matching of multiple socket contacts and multiple pin contacts 12, thereby realizing the electrical connection between the female charging terminal 1 and the charging gun 200, and realizing the charging of the vehicle.

[0067] This invention does not change the original structure of the charging gun 200, but only makes a new structural design for the charging structure on the vehicle, which can increase the scope of application.

[0068] The present invention also proposes a control method for detaching the vehicle charging port from the charging gun 200.

[0069] The control method for detaching the vehicle charging port from the charging gun 200 according to an embodiment of the present invention is applicable to the vehicle charging port assembly 100 in any of the above embodiments, and the control method includes: S1: Obtain vehicle speed information, charging information, and fire information.

[0070] S11: Control system of vehicle charging port assembly 100, which acquires vehicle speed information and vehicle charging information. The control module of the vehicle charging port assembly 100 control system can be electrically connected to the vehicle control module so that the vehicle control module can transmit the vehicle speed information and the vehicle charging information to the control module of the vehicle charging port assembly 100. S12: Based on the vehicle speed information and the vehicle charging information, determine whether the vehicle's current speed is zero and whether it is in a charging state. When it is determined that the vehicle's current speed is zero and the vehicle is in a charging state, the on-board fire source recognition system and the vehicle charging port assembly 100 start working. When it is determined that the vehicle's current speed is not zero or the vehicle is not in a charging state, return to the initial step. S13: The vehicle-mounted fire source identification system identifies and determines the surrounding fire situation, determines whether there is a fire risk, and when it is determined that there is a fire risk, it transmits the fire information to the control system of the vehicle charging port assembly 100. S2: Based on vehicle speed information, charging information and fire information, control the disassembly structure 3 to disassemble the connecting component 6, and during the disassembly process, control the electromagnetic drive component 5 to apply magnetic attraction force to the charging female terminal 1 and the charging male terminal 2, and after the disassembly is completed, control the electromagnetic drive component 5 to apply magnetic repulsion force to the charging female terminal 1 and the charging male terminal 2.

[0071] S21: After receiving information that the vehicle speed is zero, the vehicle is in a charging state and there is a fire risk, the control system of the vehicle charging port assembly 100 controls the vehicle charging port assembly 100 to cut off the power, so that the vehicle is in a non-charging state. S22: After power failure, the control system of the vehicle charging port assembly 100 controls the electromagnetic drive component 5 to apply magnetic attraction force to the charging female terminal 1 and the charging male terminal 2, and controls the magnitude and direction of the current of the electromagnetic drive component 5 so that the charging female terminal 1 and the charging male terminal 2 do not move relative to each other. S23: After the magnetic attraction force stabilizes, the control system of the vehicle charging port assembly 100 controls the disassembly structure 3 to disassemble the connecting component 6, and continuously controls the electromagnetic drive component 5 to work during the disassembly process, continuously applying magnetic attraction force to the charging female terminal 1 and the charging male terminal 2, and continuously controlling the magnitude and direction of the current of the electromagnetic drive component 5 so that the charging female terminal 1 and the charging male terminal 2 do not move relative to each other; wherein, the drive component 31 of the disassembly structure 3 can move for time t0 to complete the disassembly of the connecting component 6, that is, the disassembly time of the connecting component 6 is also t0.

[0072] S23: After disassembly, the control system of the vehicle charging port assembly controls the electromagnetic drive component 5 to apply magnetic repulsion force to the charging female terminal 1 and the charging male terminal 2, so that the charging male terminal 2 is ejected and separated from the charging female terminal 1 under the dual action of magnetic repulsion force and elastic force.

[0073] It should be noted that a separate controller can be provided for the electromagnetic drive component 5 and electrically connected to the control module of the control system of the vehicle charging port assembly 100. The controller can switch the current direction and control the current magnitude of the electromagnetic drive component 5.

[0074] According to the control method for detaching the vehicle charging port from the charging gun 200 according to the embodiment of the present invention, reliable separation of the male charging terminal 2 and the female charging terminal 1 can be achieved when a fire occurs around the vehicle, thereby realizing emergency detachment of the charging gun 200 from the female charging terminal 1 and effectively protecting the vehicle.

[0075] The present invention also proposes a vehicle.

[0076] The vehicle according to an embodiment of the present invention includes the vehicle charging port assembly 100 of any of the above embodiments.

[0077] By designing the charging structure as a split type, namely a female charging terminal 1 connected to the vehicle body 300 and a male charging terminal 2 detachably connected to the female charging terminal 1 via a connecting component 6, and allowing the charging gun 200 to be inserted through the male charging terminal 2 to connect with the female charging terminal 1, the normal charging function of the vehicle is ensured. Simultaneously, in the event of a fire in the vicinity, the disassembly structure 3 can disassemble the connecting component 6. During disassembly, the electromagnetic drive component 5 applies a magnetic attraction force to prevent relative movement between the female charging terminal 1 and the male charging terminal 2, keeping the elastic element 4 in a state of maximum compression. After the disassembly of the connecting component 6 is completed, the male charging terminal 2 can be ejected under the combined action of the elastic thrust applied by the elastic element 4 and the magnetic repulsion applied by the electromagnetic drive component 5, thereby separating the vehicle charging structure from the external charging gun 200. This ensures that the vehicle can safely leave the danger zone without damaging the charging structure, protecting both the charging gun 200 and the vehicle charging structure, and guaranteeing vehicle safety.

[0078] According to an embodiment of the present invention, by providing the above-described vehicle charging port assembly 100, the vehicle's safety performance is improved, and effective protection of the vehicle is achieved.
