Description

Technical Field

[0001] This utility model relates to a sealing cover for compatiblely sealing DC and AC charging ports of a vehicle, a charging panel for a vehicle, and a vehicle. Background Technology

[0002] Currently, electric vehicles are typically equipped with two charging ports, one for DC charging and one for AC charging, to be used with different charging devices. During the charging process, the unused charging port is exposed to the elements, which may be susceptible to rain, sand, and / or dust intrusion, leading to electrical risks such as short circuits, open circuits, and loose connections, or even damage to the charging port and / or charging equipment, potentially threatening the safety of people and vehicles.

[0003] To avoid this problem, existing technology proposes providing a cover for both DC and AC charging ports to close unused ports during charging. However, since the different charging ports are of different sizes, these covers are not interchangeable, incur additional manufacturing costs and weight, and also increase the user's operational steps when charging the vehicle, thus wasting the user's time.

[0004] In particular, it should be pointed out that, in order to achieve a seal, the covers of existing technologies are usually made of soft materials, such as rubber, as a whole. However, although such covers can fit tightly with the corresponding charging ports, their soft texture and interference fit design make it difficult for users to plug and unplug them, and often, during the unplugging process, another cover connected by a cord may also be pulled out.

[0005] For the reasons mentioned above, there is an urgent need for a charging port sealing solution that is easy to operate, easy to plug and unplug, reduces manufacturing costs, and lightens weight. Utility Model Content

[0006] The objective of this invention is to provide a sealing cover for compatiblely sealing DC and AC charging ports of a vehicle, a charging panel for a vehicle, and a vehicle that facilitates user operation, is easy to plug and unplug, and simultaneously reduces manufacturing costs and weight.

[0007] The first aspect of this utility model relates to a sealing cover for compatiblely sealing DC and AC charging ports of a vehicle, wherein the sealing cover is manufactured by two-component injection molding and includes a cover body made of a rigid material and a sealing ring made of a soft material, wherein the cover body has a guide portion protruding from a base surface on the sealing side facing the charging port for guiding the sealing cover into the charging port, and the sealing ring is disposed on the periphery of the base surface on the sealing side and for conforming to the end face of the outer periphery of the charging port when the sealing cover covers the charging port.

[0008] Within the scope of this utility model, "vehicle" should be understood as an electric vehicle or an electrically driven vehicle, such as a battery-powered vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV) with an internal combustion engine and an electric drive system. The vehicle can be configured as any type of vehicle, by means of which one or more persons and / or goods can be transported. The vehicle is particularly a car, truck, motorcycle, bus, etc. Here, the vehicle is driven by a battery at least partially. The battery is particularly referred to as a vehicle power battery, which may include multiple battery cells. The battery is charged by connecting to a charging device. The charging device can be understood as a charger or charging station for charging the vehicle's battery. The charging station can be configured in any form, such as a wall-mounted charging box, a single charging pile, or a charging pile in a charging station.

[0009] The sealing cover according to this utility model is universal for both DC and AC charging ports of a vehicle. This means that the same sealing cover can seal both DC and AC charging ports. This compatibility allows the other unused charging port to be closed when one of the charging ports is being used for charging. Furthermore, based on the compatibility of the sealing cover, the above-mentioned technical advantages can be achieved with only one sealing cover for vehicles with dual charging ports, which undoubtedly reduces the manufacturing cost and quality of the sealing cover.

[0010] According to this utility model, the sealing cap is manufactured by two-component injection molding or two-color injection molding. The sealing cap includes a cap body made of a rigid material and a sealing ring made of a soft material. Thus, the rigid cap body and the soft sealing ring can be integrally molded in one manufacturing process, eliminating the need for subsequent assembly steps, thereby reducing manufacturing costs and time. The cap body has a guide portion protruding from the base surface on the sealing side facing the charging port to guide the sealing cap into the charging port. The guide portion made of rigid material allows the user to smoothly and accurately insert the sealing cap into the charging port, thereby facilitating user operation and making the sealing cap easy to insert and remove. The sealing ring, made of soft material, is placed on the periphery of the base surface on the sealing side and is used to fit against the outer end face of the charging port when the sealing cover is placed on the charging port. This ensures the waterproof and dustproof sealing of the charging port, preventing rainwater, sand and / or dust from entering the charging port, avoiding circuit risks such as short circuits, open circuits, and loose connections, improving charging safety, and ensuring the normal operation of the charging port and charging equipment.

[0011] According to one embodiment of this utility model, the guide portion of the sealing cover may include a surrounding guide wall for extending into the gap between each terminal of the AC charging port and the inner wall. Here, the surrounding guide wall can be inserted into the gap between each terminal of the AC charging port and the inner wall, similar to the insertion sleeve of a charging gun, ensuring good movement guidance during insertion. It should be noted that the surrounding guide portion does not need to perfectly correspond to the approximately circular or segmented shape of the DC charging port in order to be compatible with it; one or more arc-shaped segments and a straight segment extending along the inner wall of the AC charging port are sufficient to meet the guiding requirements. Here, the vehicle's charging port can be constructed to conform to standards such as GB / T 18487.1-2015, GB / T 20234.1-2015, GB / T 20234.2-2015, GB / T 20234.3-2015, GB / T27930-2015 and / or GB / T 32960.3-2016.

[0012] According to one embodiment of this utility model, the surrounding guide wall may have at least one first friction locking portion made of soft material on its outer peripheral side for pressing against the inner peripheral wall of the AC charging port. Here, in order to ensure that the sealing ring of the sealing cover can fit tightly against the end face of the outer periphery of the charging port, the sealing cover is pressed by frictional locking between the first friction locking portion and the inner peripheral wall of the AC charging port in the axial direction. Exemplarily, three first friction locking portions may be provided, two of which are located on the aforementioned arcuate section and one of which is located on the aforementioned straight section. Particularly advantageously, the plurality of first friction locking portions may be evenly distributed in the circumferential direction.

[0013] According to one embodiment of this utility model, the height of the surrounding guide wall can be designed to block the terminals of the DC charging port or to prevent contact with the terminals of the DC charging port. Since the terminals of the DC charging port are usually located in a deeper position for safety reasons, the height design of the surrounding guide wall can be used to avoid the terminals in the DC charging port.

[0014] According to one embodiment of this utility model, the guide portion may include a three-pronged star-shaped guide rib for extending into the gap between the terminals of the DC and AC charging ports. Here, the guide rib may, for example, be positioned between the ground terminal (i.e., the PE terminal) and the two spare terminals (i.e., NC1 or L2 terminals and NC2 or L3 terminals) extending into the AC charging port, and between the ground terminal (i.e., the PE terminal), the DC positive terminal (i.e., the DC+ terminal), and the DC negative terminal (i.e., the DC- terminal) extending into the DC charging port. Therefore, the guide rib will have a greater height than the surrounding guide wall.

[0015] According to one embodiment of this utility model, the guide portion may include at least one guide post, the guide post having a second friction locking portion made of soft material on one side, and pressing against the DC positive terminal and / or DC negative terminal of the DC charging port through the second friction locking portion. In order to ensure that the sealing ring fits tightly against the end face of the outer periphery of the charging port when closing the DC charging port, an axial clamping force can be generated by the frictional locking of the second friction locking portion with at least one of the two main terminals in the DC charging port.

[0016] According to a preferred embodiment of this utility model, the guide portion may include a trapezoidal guide structure located outside the sealing ring and cooperating with the charging gun guide groove. The bottom edge of the trapezoidal guide structure may be constructed as an arc and provided with a third friction locking portion made of soft material for pressing against the outer peripheral wall of the DC charging port. Here, a trapezoidal area extends outward from the outer side of the circular sealing ring, making the sealing cover generally oval or elliptical. The trapezoidal guide structure can extend into the charging gun guide groove of the charging port. Compared with a circular sealing cover, this external shape can provide better directional indication for the user and is more convenient for the user's operation. At the same time, the trapezoidal guide structure can, to a certain extent, prevent rainwater from sliding down from above the charging panel, further improving the sealing effect. In addition, the third friction locking portion can also generate a pressing force on the sealing cover by friction locking with the outer peripheral wall of the DC charging port in the axial direction.

[0017] According to one embodiment of this utility model, the guide portion may include one or more guide pieces located between the third friction locking portion and the surrounding guide wall, the guide pieces being configured to guide along the outer peripheral wall of the AC charging port and the inner peripheral wall of the DC charging port. Particularly preferably, the peripheral wall of the AC charging port can be clamped by the guide pieces and the surrounding guide wall, and / or the peripheral wall of the DC charging port can be clamped by the guide pieces and the third friction locking portion. This further improves the movement guidance and axial clamping of the sealing cover.

[0018] According to one embodiment of this utility model, the sealing cover has a protrusion for user operation on the operating side opposite to the sealing side. Here, the protrusion can be designed to facilitate pinching with the user's thumb and forefinger for insertion and removal operations.

[0019] According to one embodiment of this utility model, the rigid material is glass fiber reinforced polypropylene (PP+GF), and / or the flexible material is ethylene propylene diene trimer (EPDM). The rigid material is particularly preferably PP+GF45, i.e., a material reinforced by a mixture of polypropylene (PP) and glass fiber (GF) in a 45% ratio.

[0020] The second aspect of this utility model relates to a charging panel for a vehicle, the charging panel having a DC charging port and an AC charging port, characterized in that the charging panel includes a sealing cover according to this utility model.

[0021] According to one embodiment of this utility model, the sealing cover can be connected to the charging panel via an elastic cord. Here, the connection via the elastic cord prevents the sealing cover from being lost.

[0022] According to one embodiment of this utility model, the sealing cover can be inserted into an unused charging port when charging the vehicle.

[0023] According to one embodiment of this utility model, the charging port may protrude from the charging panel or be flush with the charging panel.

[0024] A third aspect of this utility model relates to a vehicle, wherein the vehicle includes a sealing cover according to this utility model or a charging panel according to this utility model.

[0025] It should be noted that the features, functions, effects, and advantages of one aspect of this utility model can also be referred to the above description of other aspects of this utility model. Furthermore, the various aspects described in this utility model can be combined with each other in various ways.

[0026] Other features of this invention are derived from the accompanying drawings and the detailed description. All features and combinations thereof mentioned above in the specification, as well as features and combinations thereof mentioned below in the detailed description and / or shown separately in the drawings, can be used not only in the corresponding combinations given, but also in other combinations, or in their individual states.

[0033] Figure 7 This is a perspective view of the sealing cover in one embodiment of the present invention when the AC charging port is closed. Detailed Implementation

[0034] Figure 1 A schematic diagram of a sealing cap according to an embodiment of the present invention is shown. Figure 1 As shown, the sealing cover 1 for compatiblely sealing the DC and AC charging ports of a vehicle is manufactured by two-component injection molding and includes a cover body 2 made of a rigid material (shown in black in the figure) and a sealing ring 3 made of a soft material (shown in green in the figure). The cover body 2 has a guide portion protruding from the base surface 4 on the sealing side SS facing the charging port for guiding the sealing cover 1 into the charging port. The sealing ring 3 is disposed on the periphery of the base surface 4 of the sealing side SS and is used to fit against the end face of the outer periphery of the charging port when the sealing cover 1 covers the charging port.

[0035] Figure 2 and Figure 3 Schematic diagrams are shown with the sealing cover 1 closed when the AC charging port 16 is closed and when the DC charging port 14 is closed. (By...) Figure 2 and Figure 3 It is understood that the sealing cover 1 is universal for both the DC charging port 14 and the AC charging port 16 of the vehicle. The same sealing cover 1 can seal both the DC charging port 14 and the AC charging port 16. This allows the user to seal the other unused charging port while using one of the two ports. Compared to the existing technology that provides separate covers for each charging port, this undoubtedly reduces the manufacturing cost and quality of the sealing cover 1.

[0036] Furthermore, the rigid cover body 2 and the soft sealing ring 3 of the sealing cover 1 can be integrally molded in one manufacturing process using a two-component injection molding process, eliminating the need for subsequent assembly steps, thereby reducing manufacturing costs and time. The cover body 2 has a guide made of rigid material for guiding the sealing cover 1 into the charging port. This guide allows the user to smoothly and accurately insert the sealing cover 1 into the charging port, thus facilitating user operation and making the sealing cover easy to insert and remove. The sealing ring 3, made of soft material, is disposed around the base surface 4 of the sealing side SS and is used to fit against the outer end face of the charging port when the sealing cover 1 covers the charging port. This ensures the waterproof and dustproof sealing of the charging port, preventing rainwater, sand and / or dust from entering the charging port, avoiding the circuit risks such as short circuits, open circuits, and loose connections, improving charging safety, and ensuring the normal operation of the charging port and charging equipment.

[0037] from Figure 2 and 3 Also refer to the following Figure 7 It can also be seen that the sealing cover 1 has a protrusion 13 for user operation on the operating side OS opposite to the sealing side SS. The protrusion 13 extends vertically here, which can be easily pinched by the user's thumb and forefinger to perform insertion and removal operations.

[0038] The following is made with the help of Figure 1 and the following Figures 4 to 7 The present invention describes in detail various structural schemes of the guide portion of the sealing cap 1 according to an embodiment of the present invention. Figure 4 As shown Figure 2 The positional relationship between each guide portion and the outline of the AC charging port 16 when the sealing cover 1 is inserted into the AC charging port 16 as shown. Figure 7 Then it shows Figure 2 The diagram shows a perspective view of the charging panel P. Figure 5 As shown Figure 3 When the sealing cap 1 is inserted into the DC charging port 14 as shown, the outline of each guide portion and the positional relationship of each terminal are shown.

[0039] First, the guide portion of the sealing cover 1 preferably includes a surrounding guide wall 5 for extending into the gap between the terminals of the AC charging port 16 and the inner wall. Thus, the sealing cover 1 can be inserted into the AC charging port 16 like a plug sleeve of a charging gun and provides good movement guidance during the insertion process. The surrounding guide wall 5 does not need to strictly correspond to the approximately circular or segmental shape of the AC charging port 16. Figure 1As shown, the surrounding guide wall 5 mainly includes two arc-shaped sections corresponding to the arc-shaped orientation of the inner wall of the AC charging port 16 and one straight section corresponding to its straight orientation. The other sections of the surrounding guide wall 5 are recessed inward to avoid the guide post 8 and hole L, which will be described in detail later.

[0040] Particularly advantageously, the surrounding guide wall 5 is provided with at least one, in this case three, first friction-locking portions 6 made of soft material on its outer peripheral side for pressing against the inner peripheral wall of the AC charging port 16. The axial frictional locking between the first friction-locking portions 6 and the inner peripheral wall of the AC charging port 16 generates a clamping force on the sealing cover 1, thereby ensuring that the sealing ring 3 of the sealing cover 1 fits tightly against the end face of the outer periphery of the AC charging port 16, i.e. Figure 3 The charging panel P surrounding the AC charging port 16 is shown on a plane.

[0041] Here, the fitting relationship between the first friction locking part 6 and the inner peripheral wall of the AC charging port 16 can also be referred to Figure 5 To explain. From Figure 5 As can be seen, the three first friction locking parts 6, made of soft material, are located on the two arc-shaped sections and the one straight section, respectively, and are distributed approximately evenly in the circumferential direction of the surrounding guide wall 5. Therefore, after the sealing cap 1 is inserted into the AC charging port 16, the three first friction locking parts 6 will press against the inner circumferential wall of the AC charging port 16, thus causing the sealing ring 3 to be pressed evenly against the outer circumferential end face of the AC charging port 16, that is, on the plane of the charging panel P surrounding the AC charging port 16, thereby achieving an optimized sealing effect.

[0042] In addition to the surrounding guide wall 5, the guide portion may also include a trident-shaped guide rib 7 for extending into the gap between the terminals of the DC charging port 14 and the AC charging port 16. The trident-shaped guide rib 7 can be inserted approximately centrally into the different charging ports and avoid the terminals therein. For example, in the AC charging port 16, the guide rib 7 can extend between the ground terminal and the two spare terminals; while in the DC charging port 14, it can extend between the ground terminal PE terminal, the DC positive terminal DC+, and the DC negative terminal DC-.

[0043] In addition, the guide portion may also include guide posts 8, particularly two guide posts 8. The guide posts 8 may, for example, be located on the outer side of the surrounding guide wall 5, particularly in the region where the surrounding guide wall 5 is recessed inward relative to the shape of the AC charging port 16. To ensure that the sealing ring 3 fits tightly against the end face 18 of the outer periphery of the DC charging port 14 when it is closed, the guide post 8 may also have a second friction locking portion 9 made of soft material on one side, and this second friction locking portion 9 presses against the DC positive terminal DC+ and / or DC negative terminal DC- of the DC charging port 14. Figure 6 As shown, the two second friction locking parts 9 press against the two DC terminals from above. Considering the generally deep location of the DC terminals, the guide post 8 can have a greater height than the surrounding guide wall 5.

[0044] exist Figure 6 For clarity, the complete surrounding guide wall 5 is not shown. However, it can be seen from the partial view that although the surrounding guide wall 5 does not bypass the terminals of the DC charging port 14, it does not hinder the insertion of the sealing cover 1 into the AC charging port 14. Here, the height of the surrounding guide wall 5 can be designed to block the terminals of the DC charging port 14 or not to contact the terminals of the DC charging port 14.

[0045] In addition to the aforementioned surrounding guide wall 5, trident-shaped guide ribs 7, and guide posts 8, the guide portion preferably also includes a trapezoidal guide structure 10 located outside the sealing ring 3 and cooperating with the charging gun guide groove 17. The trapezoidal guide structure 10 makes the sealing cover 1 generally oval or elliptical in shape. Compared to a generally circular sealing cover, the trapezoidal guide structure 10 can further assist the user in correctly inserting the sealing cover 1 into the charging gun guide groove 17 of the AC and / or DC charging port, making the operation more convenient. Simultaneously, the trapezoidal guide structure 10 can, to some extent, prevent rainwater from sliding down from above the charging panel P, further improving the sealing effect.

[0046] Particularly preferably, the bottom edge of the trapezoidal guide structure 10 can be constructed as an arc and provided with a third friction locking part 11 made of soft material for pressing against the outer peripheral wall 19 of the DC charging port 14. Here, the third friction locking part 11 can also generate a pressing force on the sealing cover 1 by friction locking with the outer peripheral wall 19 of the DC charging port 14 in the axial direction.

[0047] Particularly preferably, the guide portion may include one or more guide pieces 12 located between the third friction locking portion 11 and the guide wall 5, the guide pieces 12 being configured to run along the outer peripheral wall of the AC charging port 16 (see...). Figure 5) and the inner peripheral wall of the DC charging port 14 (see Figure 6 The guide plate 12 can be used to clamp the peripheral wall of the AC charging port 16 with the surrounding guide wall 5, and / or the peripheral wall of the DC charging port 14 can be clamped with the guide plate 12 and the third friction locking part 11. This further improves the movement guidance and axial clamping of the sealing cover 1.

[0048] Preferably, the rigid material can be glass fiber reinforced polypropylene, i.e., PP+GF, and / or the flexible material is ethylene propylene diene trimer, i.e., EPDM. The rigid material is particularly preferably PP+GF45, i.e., a material reinforced by a mixture of polypropylene (PP) and glass fiber (GF) in a 45% ratio.

[0049] exist Figure 2 , Figure 3 and Figure 7 Also shown is a charging panel P for a vehicle according to an embodiment of the present invention, the charging panel P having both a DC charging port 14 and an AC charging port 16, and the charging panel including a sealing cover 1 according to the present invention.

[0050] To ensure the sealing cap is not lost, the sealing cap 1 can be connected to the charging panel P via an elastic cord 15. For this purpose, a hole L is provided on the cover body 2 of the sealing cap 1 for inserting the elastic cord 15. The elastic cord 15 does not affect the relocation of the sealing cap 1 or the user's insertion and removal operations.

[0051] On the charging panel 1, the sealing cover 1 is inserted into the idle charging port when the vehicle is charging. Thus, when charging with the other charging port, the idle charging port can be sealed off from the external environment by the sealing cover, preventing the intrusion of rain, sand and / or dust, and ensuring the safety of the charging port.

[0052] exist Figure 7 The diagram also shows a preferred arrangement of the charging panel. Here, the DC charging port 14 protrudes from the charging panel P, while the AC charging port 16 is flush with the charging panel. The DC charging port 14 is offset outwards, and its outer peripheral end face 18 bulges outwards relative to the plane of the charging panel P. When the DC charging port 14 is closed with the sealing cover 1, the sealing ring 3 of the sealing cover 1 adheres to the bulging end face 18 along its entire circumference. For the AC charging port 16, which is flush with the charging panel P, the sealing ring 3 of the sealing cover 1 rests against the area of ​​the charging panel P located at the outer periphery of the AC charging port 16.

The positional descriptions chosen in the specification, such as, for example, top, bottom, left, right, etc., refer to the direct description and the accompanying drawings, and can be adapted to new positions according to their meaning when the positions change.
