[0050] Various specific embodiments of the present invention will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. Where possible, the same or similar figure numbers used in this application refer to the same parts.

[0051] Figure 1A is a three-dimensional diagram of a charging port or fuel filler cap assembly of the first embodiment of the present application, Figure 1B yes Figure 1A Exploded view of the charging port or fuel filler cap assembly. Figure 1A and Figure 1B As shown, the charging port or fuel filler cap assembly 100 includes a housing 102, a cover 101, a connecting rod mechanism 103 and a power device 104. The housing 102 can be connected to the fuel filler or charging port. The power device 104 is installed in the housing 102. One end of the connecting rod mechanism 103 is connected to the cover 101 through the shaft assembly 170, and the other end of the connecting rod mechanism 103 is connected to the power device 104 and the housing 102 through the shaft assembly 180. The power device 104 can drive the connecting rod mechanism 103 to rotate, thereby driving the cover 101 to move between the closed position and the open position of the cover 101 relative to the housing 102, thereby covering or exposing the fuel filler or charging port connected to the housing 102. The shaft assembly 170 and the shaft assembly 180 each include a pair of shafts.

[0052] like Figure 1A As shown, the charging port or fuel filler cap assembly has a height direction H1, a length direction L1 and a width direction W1. When the cover 101 is in the closed position and the open position relative to the shell 102, the cover 101 translates relative to the shell along the height direction H1 and the length direction L1. That is to say, when the cover 101 moves between the open position and the closed position, each part of the cover moves an equal distance relative to the corresponding part of the shell, and the movement trajectory of each part of the cover is the same. In this embodiment, the length direction L1 is the first direction and the height direction H1 is the second direction. The cover 101 can move relative to the shell 102 in the first direction, and can move relative to the shell 102 in the second direction. The movement of the cover 101 relative to the shell 102 causes the cover 101 to be displaced in the first direction and the second direction relative to the shell 102.

[0053] Figure 2A yes Figure 1B A three-dimensional diagram of the middle shell. Figure 2Byes Figure 2A A three-dimensional view of the middle shell from another angle. Figure 2A and Figure 2B The front and back sides of the housing 102 are shown.

The connecting rod matching area 216 has a connecting rod opening 226, and the connecting rod mechanism 103 passes through the connecting rod opening 226 and can move in the connecting rod opening 226. The connecting rod opening 226 has an inner edge 260, and the inner edge 260 extends smoothly along the width direction W1 of the charging port or the fuel filler cap assembly. In other embodiments of the present application, the connecting rod matching area 216 is located at the bottom 235 or the side edge 236, or at the side 202. The rear side of the main body 201 is provided with a mounting structure 250 for connecting with the interior of the vehicle. The working area 205 has a first side 241 and a second side 242 in the first direction, wherein the first side 241 is located upstream of the second side 242 in the moving direction of the cover 101 from the closed position to the open position. The connecting rod matching area 216 is arranged along the first direction with the working area 205, and the connecting rod matching area 216 is close to the second side 242. In one embodiment of the present application, the connecting rod matching area 216 is located downstream of the working area 205 in the moving direction of the cover 101 from the closed position to the open position.

[0055] In the present application, the working area 205 is an area that can be matched or aligned with the charging port or the refueling port, and is not limited to a specific component on the housing 102, and may include non-physical parts. In some embodiments, the working area 205 is set to coincide with the opening of the charging port or the refueling port. In other embodiments, the working area 205 is only a reserved installation space, and no physical structure is set. Similarly, the connecting rod matching area 216 is an area through which the connecting rod mechanism 103 can pass. The connecting rod matching area 216 is provided with an opening that matches the shape of the connecting rod mechanism, or is a hollow area, and the connecting rod mechanism 103 can move in the hollow area.

[0056] The main body 201 further includes a limiting portion 288 , which is an opening penetrating the bottom 235 . The limiting portion 288 can cooperate with the cover 101 to clamp the cover 101 onto the housing 102 .

[0057] like Figure 2A and Figure 2B As shown, the side portion 202 is connected to the connecting rod matching area 216 and is arranged on one side of the working area 205. The side portion 202 includes a connecting rod accommodating area 207, and the connecting rod accommodating area has a connecting rod accommodating space 271 for accommodating the connecting rod mechanism 103. The connecting rod accommodating space 271 is connected to the connecting rod opening 226. In the first direction, the connecting rod accommodating area 207 does not overlap with the working area 205. The side portion 202 also includes a power device mounting portion 290 for mounting the power device 104. It should be noted that the connecting rod accommodating area 207 includes a semi-open accommodating space. In the present application, when the connecting rod mechanism 103 enters the connecting rod accommodating area 207, the connecting rod mechanism 103 is allowed to exceed the edge of the housing 102 at the connecting rod accommodating area 207.

[0058] Figure 3A yes Figure 1B A three-dimensional diagram of the middle cover. Figure 3B yes Figure 3A A three-dimensional view of the middle cover from another angle. Figure 3A and Figure 3B The front and back sides of the cover 101 are shown.

[0059] like Figure 3A and Figure 3B As shown, the cover 101 is generally flat and has a front side 311 and a rear side 312, the front side 311 is arranged toward the outside of the vehicle, and the rear side 312 is arranged toward the housing 102. In a first direction, the cover 101 has a first side portion 321 and a second side portion 322. In the closed position of the cover 101, the first side portion 321 is close to the first side 241 of the working area, and the second side portion 322 is close to the second side 242 of the working area. That is, in the movement direction of the cover 101 from the closed position to the open position, the first side portion 321 is located upstream of the second side portion 322.

[0060] The rear side 312 of the cover 101 has a connection portion 290, which is close to the second side portion 322. The connection portion 290 includes a first connecting rod mounting portion 291 and a second connecting rod mounting portion 292, which are respectively used to mount a pair of shafts in the shaft assembly 170, and the first connecting rod mounting portion 291 and the second connecting rod mounting portion 292 are staggered so that the two shafts in the shaft assembly 170 are not coaxially arranged.

[0061] The cover 101 further includes a protrusion 388, which protrudes from the surface of the rear side 312 and is close to the first side portion 321. The protrusion 388 can enter the stopper 288 of the housing 102, so that the cover 101 is not easy to move relative to the housing 102 along the extension direction of the cover 101 in the closed position.

[0062] Figure 4A yes Figure 1B The three-dimensional diagram of the middle connecting rod mechanism. Figure 4B yes Figure 4A Side view of the middle linkage. Figure 4A and Figure 4B The structure of the connecting rod mechanism is shown.

[0063] like Figure 4A and Figure 4B As shown, the connecting rod mechanism 103 includes a first connecting rod 401 and a second connecting rod 402. The first connecting rod 401 and the second connecting rod 402 have similar but different shapes. In this embodiment, the first connecting rod 401 and the second connecting rod 402 are staggered. When viewed from the side, the first connecting rod 401 and the second connecting rod 402 do not overlap.

[0064] The first connecting rod 401 includes a first upper connecting portion 412, a first gooseneck portion 413 and a first lower connecting portion 414. The first upper connecting portion 412 has an axis mounting hole 441, so that the first upper connecting portion 412 can be hinged to the first connecting rod mounting portion 291 of the cover 101 through an axis. The first lower connecting portion 414 has an axis mounting hole 443, so that the first lower connecting portion 414 can be hinged to the housing 102 through an axis. The first gooseneck portion 413 includes a first upper smooth section 417, a first curved section 418 and a first lower smooth section 419, which are connected in sequence. The first curved section 418 is roughly arc-shaped, and the outer surface of the first curved section 418 forms a first arc. The first upper smooth section 417 and extends from one end of the first curved section 418 in a direction away from the center of the first arc. The first lower smooth section 419 extends from one end of the first curved section 418 in a direction close to the center of the first arc. The first lower connecting portion 414 coincides with the center of the first arc. The first lower connecting portion 414 is hinged to the housing 102 via a connecting shaft.

[0065] Similarly, the second connecting rod 402 includes a second upper connecting portion 422, a second gooseneck portion 423, and a second lower connecting portion 424. The second upper connecting portion 422 has an axis mounting hole 442, and the second upper connecting portion 422 is hinged to the second connecting rod mounting portion 292 of the cover 101 through the axis. The second lower connecting portion 424 has an axis mounting hole 444, and the axis mounting hole 444 is in an anti-rotation shape, so that the second lower connecting portion 424 can be fixedly connected to the power device 104 through the axis. The second gooseneck portion 423 includes a second upper smooth section 427, a second curved section 428, and a second lower smooth section 429, and the second upper smooth section 427, the second curved section 428, and the second lower smooth section 429 are connected in sequence. The second curved section 428 is roughly arc-shaped, and the outer surface of the second curved section 428 forms a second arc. The second upper smooth section 427 and the second curved section 428 extend from one end of the second curved section 428 in a direction away from the center of the second arc. The second lower smooth section 429 extends from one end of the second curved section 428 toward the center of the second arc. The second lower connecting portion 424 coincides with the center of the second arc.

[0066] See also Figure 4B As shown, the connecting axis of the first upper connecting portion 412 and the cover 101 and the connecting axis of the second upper connecting portion 422 and the cover 101 are not arranged on the same axis, that is, the axis mounting holes 441 and 442 are not arranged on the same axis. The connecting axis of the first lower connecting portion 414 and the housing 102 and the connecting axis of the second lower connecting portion 424 and the power device 104 are not arranged on the same axis. In the first direction, there is a spacing between the connecting axis of the first upper connecting portion 412 and the cover 101 and the connecting axis of the second upper connecting portion 422 and the cover 101, and there is a spacing between the connecting axis of the first lower connecting portion 414 and the housing 102 and the connecting axis of the second lower connecting portion 424 and the power device 104. In this embodiment, the diameters of the first arc and the second arc are different, and the first arc and the second arc do not overlap.

[0067] Figure 5A yes Figure 1A A perspective view of the charging port or fuel filler cap assembly hiding the housing, Figure 5B yes Figure 5A A perspective view of another angle of the charging port or fuel filler cap assembly of the housing is hidden in FIG. Figure 5A and Figure 5B The matching relationship between the connecting rod mechanism, the cover and the power device is shown.

[0068] like Figure 5A As shown, the first link 401 is hinged to the first link mounting portion 291 of the cover 101 through a connecting shaft, and the second link 402 is hinged to the second link mounting portion 292 of the cover 101 through a connecting shaft. The connection between the first link 401 and the second link 402 and the cover 101 is close to the second side portion 322 of the cover 101.

[0069] like Figure 5B As shown, one end of the second connecting rod 402 is hinged to the cover 101, and the other end of the second connecting rod 402 is fixedly connected to the power device 104 through the connecting shaft, so that the power device 104 can drive the second connecting rod 402 to rotate through the connecting shaft. The two ends of the first connecting rod 401 are respectively connected to the cover 101 and the housing 102. When the second connecting rod 402 is driven to rotate, the first connecting rod 401 rotates with the second connecting rod 402. During the movement of the connecting rod mechanism 103, the first connecting rod 401 and the second connecting rod 402 do not overlap, so that the cover 101 can move translationally relative to the housing 102.

[0070] Fig. 6A yes Figure 1A A perspective view of the cover of the charging port or fuel filler cap assembly in the closed position, Figure 6B yes Figure 1A A perspective view of the cover of the charging port or fuel filler cap assembly in the open position, Fig. 6A and Figure 6B The working process of the cover of the charging port or fuel filler cap assembly is shown.

[0071] like Fig. 6A As shown, when the cover 101 is in the closed position, the cover 101 covers the housing 102, thereby shielding the working area 205 of the housing 102. The outer surface of the cover 101 is substantially flush with the side edge 236 of the housing 102, or slightly higher than the side edge 236. Figure 6B As shown, when the cover 101 is in the open position, the cover 101 leaves the housing 102, thereby exposing the working area 205. The cover 101 is located on one side of the working area 205 in the first direction, and is located above the connecting rod accommodating area 207 in the height direction of the charging port or fuel filler cap assembly. Looking along the height direction, most of the connecting rod mechanism 103 is blocked by the cover 101, and the operator cannot easily see the connecting rod mechanism, making the charging port or fuel filler cap assembly in the present application neat and beautiful.

[0072] Fig. 7A yes Fig. 6A A side view of a charging port or fuel filler cap assembly in Figure 7B yes Fig. 6A Side view of the charging port or fuel filler cap assembly behind the housing, Figure 7C yes Figure 6B A side view of a charging port or fuel filler cap assembly in Fig.7D yes Figure 6B Side view of the charging port or fuel filler cap assembly behind the housing.

[0073] like Fig. 7A and Figure 7BAs shown, when the cover 101 is in the closed position, the cover 101 covers the housing 102, and in the first direction, most of the link mechanism 103 is aligned with the link accommodating area 207. The link accommodating area 207 is located at one side of the working area 205 of the housing 102.

[0074] When the cover 101 needs to be opened, the power device 104 drives the second connecting rod 402 of the connecting rod mechanism 103 to rotate, and the second connecting rod 402 moves along the Figure 7C The second upper connecting portion 422 of the second connecting rod 402 is hinged to the cover 101, so that the second upper connecting portion 422 rotates relative to the cover 101 and drives the cover 101 to move. The first connecting rod 401 is hinged to the cover 101 and the shell 102, respectively, and the first upper connecting portion 412 and the first lower connecting portion 414 of the first connecting rod 401 are not coaxially arranged with the second upper connecting portion 422 and the second lower connecting portion 424 of the second connecting rod 402, respectively, so that the first connecting rod 401 and the second connecting rod 402 can jointly support the translational movement of the cover 101, so that the cover 101 does not rotate relative to the shell 102 during the movement. The hinge point between the first connecting rod 401 and the shell 102 enables the first connecting rod 401 to follow the movement of the second connecting rod 402 through the cover 101 without being stuck. In this embodiment, the shapes of the first connecting rod 401 and the second connecting rod 402 are similar but not the same, so that the cover 101 can move in translation.

[0075] When the cover 101 moves between the open position and the closed position, the diameters of the first curved section 418 of the first link 401 and the second curved section 428 of the second link 402 are different, so that the movement trajectories do not overlap. The shapes of the first link 401 and the second link 402 are configured so that at the inner edge 260 of the link opening 226, the outer side surfaces (i.e., the surfaces facing the inner edge 260) of the first curved section 418 and the second curved section 428 overlap. Thus, the inner edge 260 can be set to a smoothly extended shape to match the movement trajectory of the first curved section 418 and the second curved section 428 at the link opening 226.

[0076] During the movement of the cover 101, the movement tracks of the first curved section 418, the second curved section 728, the first lower smooth section 419 and the second lower smooth section 429 of the connecting rod mechanism 103 are all located on one side of the working area 205. When the cover 101 is in the closed position and the open position, the first curved section 418, the second curved section 728, the first lower smooth section 419 and the second lower smooth section 429 are aligned with the connecting rod accommodating area 207 in the first direction and are located on one side of the working area. That is, the first curved section 418, the second curved section 728, the first lower smooth section 419 and the second lower smooth section 429 of the connecting rod mechanism 103 are staggered with the working area 205 during the static and moving processes. Therefore, at the working area 205, it is not necessary to set a large amount of accommodating space for the connecting rod mechanism 103, so that the thickness of the housing 102 at the working area 205 is small, which is suitable for a narrow installation space. And when the operator looks toward the housing 102 in the open position of the cover 101, the working area 205 of the housing 102 is simple and neat.

[0077] When the cover 101 moves between the open position and the closed position, the cover 101 moves in translation relative to the housing 102. When the cover 101 is in the open position, the plane where the cover 101 is located is substantially parallel to the plane where the top of the side edge 236 of the housing 102 is located. During the movement of the cover 101, each part of the cover 101 moves an equal distance relative to the corresponding part of the housing 102, and the cover 101 cannot flip relative to the housing 102. The movement trajectory of the cover 101 is an arc, that is, the movement trajectory of each part of the cover 101 is an arc.

The charging port or fuel filler cap assembly 800 has a height direction H2, a length direction L2 and a width direction W2. In the process of the cover 801 being in the closed position and the open position relative to the shell 802, the cover 801 translates relative to the shell 802 along the height direction H2 and the width direction W1. In other words, in the process of the cover 801 moving between the open position and the closed position, each part of the cover moves the same distance relative to the corresponding part of the shell 802. In this embodiment, the width direction W1 is the first direction.

[0080] The connecting rod mechanism 803 includes a first connecting rod 901 and a second connecting rod 902 (see Fig. 9 ). The housing 802 includes a main body 831 and a side portion 832, and the side portion 832 includes a connecting rod accommodating area 807.

The connecting rod matching area 816 includes a pair of connecting rod openings 851 and 852. The first connecting rod 901 and the second connecting rod 902 can pass through the connecting rod openings 851 and 852 respectively, and move in the connecting rod openings 851 and 852 respectively. The working area 815 and the connecting rod matching area 816 are arranged along the length direction L2 of the charging port or fuel port cover assembly 800. In the width direction W1 (i.e., in the first direction), the working area has a first side 841 and a second side 842. In the direction of movement of the cover 801 from the closed position to the open position, the first side 841 is located upstream compared to the second side 842. In the width direction W2 of the charging port or fuel filler cap assembly 800, the link mating region 816 is close to the second side 842.

[0081] In the first direction, the cover 801 has a first side portion 821 and a second side portion 822. That is, in the direction of movement of the cover 801 from the closed position to the open position, the first side portion 821 is located upstream of the second side portion 822. The connection between the link mechanism 803 and the cover 801 is close to the second side portion 822.

[0082] and Figure 2A Similar to the embodiment shown, in the working area 815, there is no need to provide a large amount of accommodation space for the link mechanism 803, so that the thickness of the housing 802 in the working area 805 is small, which is suitable for a narrow installation space. In addition, when the cover 801 is in the open position, when the operator looks toward the housing 802, the working area 815 of the housing 802 is simple and neat.

[0083] Fig. 9 yes Fig. 8A Side view of the middle link mechanism. Fig. 9 As shown, the connecting rod mechanism 803 includes a first connecting rod 901 and a second connecting rod 902.

The first connecting rod 901 includes a first upper connecting portion 912, a first goose neck portion 913 and a first lower connecting portion 914. The first upper connecting portion 912 has an axis mounting hole 941, so that the first upper connecting portion 912 is hinged to the cover 801 through an axis. The first lower connecting portion 914 has an axis mounting hole 942, so that the first lower connecting portion 914 can be fixedly connected to the power device through an axis. The first goose neck portion 913 includes a first upper smooth section 917, a first curved section 918 and a first lower smooth section 919, and the first upper smooth section 917, the first curved section 918 and the first lower smooth section 919 are connected in sequence. The first curved section 918 is roughly arc-shaped. The first upper smooth section 917 and the first curved section 918 extend from one end of the first curved section 918 in a direction away from the center of the first arc. The first lower smooth section 919 extends from one end of the first curved section 918 toward the center of the first arc. The first lower connecting portion 914 coincides with the center of the first arc. The first lower connecting portion 914 is hinged to the housing 802 via a connecting shaft.

[0084] Similarly, the second connecting rod 902 includes a second upper connecting portion 922, a second gooseneck portion 923, and a second lower connecting portion 924. The second upper connecting portion 922 has an axis mounting hole 943, and the second upper connecting portion 922 is hinged to the cover 801 through the axis. The second lower connecting portion 924 has an axis mounting hole 944, so that the second lower connecting portion 924 can be hinged to the housing 802 through the axis. The second gooseneck portion 923 includes a second upper smooth section 927, a second curved section 928, and a second lower smooth section 929, which are connected in sequence. The second curved section 928 is roughly in the shape of an arc.

The second lower smooth section 929 extends from one end of the second curved section 928 and in a direction close to the center of the second arc. The second lower connecting portion 924 coincides with the center of the second arc.

[0085] See also Fig. 9As shown, the first connecting rod 901 and the second connecting rod 902 are staggered, so that the shaft mounting hole 941 of the first upper connecting part 912 and the shaft mounting hole 943 of the second upper connecting part 422 are not arranged in the same axis, and the shaft mounting hole 942 of the first lower connecting part 914 and the shaft mounting hole 944 of the second lower connecting part 924 are not arranged in the same axis. In the first direction, there is a spacing between the shaft mounting hole 941 of the first upper connecting part 912 and the shaft mounting hole 943 of the second upper connecting part 422, and there is a spacing between the shaft mounting hole 942 of the first lower connecting part 914 and the shaft mounting hole 944 of the second lower connecting part 924. That is to say, in this embodiment, the first connecting rod 901 and the second connecting rod 902 have the same shape, but are staggered in the first direction, and can also drive the connecting rod mechanism 803 to drive the cover 801 to move relative to the housing 802.

[0086] In this embodiment, the connecting rod matching area 816 is arranged close to the second side 842 of the working area 815, and the connecting rod accommodating area 807 extends from the connecting rod matching area 816 in a direction away from the first side 841 of the working area 815. That is, in the first direction, at least a portion of the connecting rod accommodating area 807 is offset from the working area 805. Thus, the thickness of the working area 805 can be set to be relatively thin, and the working area 805 is neat and beautiful. Fig. 8A The embodiments in the Figure 1A The embodiments have similar technical effects.

[0087] Fig. 10A is a three-dimensional view of the charging port or fuel filler cap assembly of the third embodiment of the present application after omitting the housing, Fig. 10B yes Fig. 10A Side view of the middle linkage and the cover when the cover is in the closed position, Fig. 10C yes Fig. 10A Side view of the center linkage and cover when the cover is in the closed position.

[0088] Figure 10A-10C The third embodiment shown is Figure 1A is similar to the first embodiment shown in Figure 10A-10C The third embodiment shown also includes a transmission device. Fig. 10A and Fig. 10CAs shown, the charging port or fuel filler cap assembly 1000 includes a cover 1001 and a connecting rod mechanism 1003. One end of the connecting rod mechanism 1003 is connected to the cover 1001. The connecting rod mechanism 1003 includes a first connecting rod 1011, a second connecting rod 1012 and a connecting member 1045. The connecting member 1045 is rod-shaped, and its two ends are pivotally connected to the first connecting rod 1011 and the second connecting rod 1012 through an axis 1038 and an axis 1039, respectively. The axis 1038 is located at the first lower connecting portion 1024 of the first connecting rod 1011, and the axis 1039 is located at the second lower connecting portion 1025 of the second connecting rod 1012. In other words, the axis 1038 is located at the portion of the first connecting rod 1011 away from the cover 1001, and the axis 1039 is located at the portion of the second connecting rod 1012 away from the cover 1001. In this embodiment, the distal end 1028 of the first lower connecting portion 1024 is connected to a power device (not shown) via a shaft, and the distal end 1029 of the second lower connecting portion 1025 is pivotally connected to the housing via a shaft. In one embodiment of the present application, the proximal ends of the first lower connecting portion 1024 and the second lower connecting portion 1025, that is, the connection point of the connecting member 1045, have a larger width.

[0089] When the power device rotates, the power device drives the first connecting rod 1011 to rotate around the distal end 1028 of the first lower connecting portion 1024. When the first connecting rod 1011 rotates, the second connecting rod 1012 is driven to rotate around the distal end 1029 of the second lower connecting portion 1025 through the connecting member 1045. The connecting member 1045 is arranged at the first lower connecting portion 1024 and the second lower connecting portion 1025, close to the rotation center of the first connecting rod 1011 and the second connecting rod 1012, which is conducive to transmitting the rotational motion of the first connecting rod 1011 to the second connecting rod 1012 as soon as possible, so that the first connecting rod 1011 and the second connecting rod 1012 rotate together.

[0090] Fig. 10B shows the closed position of the lid, Fig. 10C The cover 1001 is shown in the open position. During the movement of the cover from the closed position to the open position, the driving device drives the first connecting rod 1011 to rotate in the clockwise direction as shown by the arrow, and the first connecting rod 1011 drives the connecting member 1045 to rotate, thereby driving the second connecting rod 1012 to rotate. Thus, the second connecting rod 1012 and the first connecting rod 1011 rotate together in the direction of the arrow, and the cover 1001 is opened. During the movement of the cover from the open position to the closed position, the driving device drives the first connecting rod 1011 to rotate in the counterclockwise direction as shown by the arrow, and the first connecting rod 1011 drives the connecting member 1045 to rotate, thereby driving the second connecting rod 1012 to rotate, so that the cover 1001 is opened. Fig. 10C The position shown returns to Fig. 10B Position shown.

[0091] and Figure 1ACompared with the embodiment shown in the figure, in this embodiment, the rotational movement of the first connecting rod 1011 is transmitted through the connecting member 1045, rather than through the cover 1001. In this embodiment, the connecting member 1045 is arranged near the rotation axis of the first connecting rod 1011 and the second connecting rod 1012, which is conducive to the first connecting rod 1011 and the second connecting rod 1012 to move synchronously as soon as possible. Avoid the second connecting rod 1012 and the first connecting rod 1011 from shaking due to slight deformation during the movement due to the conduction path of the rotational movement being too long. At the same time, the position of the connecting member 1045 is arranged so that the connecting member 1045 is hidden in the shell during the movement of opening or closing the cover, so that the appearance of the charging port or the fuel filler cap assembly is neat and beautiful.

[0092] Fig.11A is a three-dimensional view of the charging port or fuel filler cap assembly of the fourth embodiment of the present application with the housing omitted, Fig. 11B yes Fig.11A Side view of the middle linkage and the cover when the cover is in the closed position, Fig. 11C yes Fig.11A Side view of the center linkage and cover when the cover is in the closed position.

[0093] Figures 11A-11C The fourth embodiment shown is Fig. 10A is similar to the first embodiment shown in Figures 11A-11C The transmission device in the fourth embodiment shown is a gear set. Fig.11A and Fig. 11C As shown, the charging port or fuel filler cap assembly 1100 includes a cap 1101 and a connecting rod mechanism 1103. One end of the connecting rod mechanism 1103 is connected to the cap 1101. The connecting rod mechanism 1103 includes a first connecting rod 1111, a second connecting rod 1112 and a gear set 1145. The gear set 1145 includes a first gear 1151, a second gear 1152 and a third gear 1153.

[0094] The first gear 1151 is fixedly connected to the first connecting rod 1111, and the second gear 1152 is fixedly connected to the second connecting rod 1112. The first gear 1151 moves synchronously with the first connecting rod 1111, and the second gear 1152 moves synchronously with the second connecting rod 1112. The connection between the first gear 1151 and the first connecting rod 1111 is located at the distal end 1128 of the first lower connecting portion 1124, and is approximately located on the axis of rotation of the first connecting rod 1111 relative to the housing. The connection between the second gear 1152 and the second connecting rod 1112 is located at the distal end 1129 of the second lower connecting portion 1125, and is approximately located on the axis of rotation of the second connecting rod 1112 relative to the housing. That is, the first gear 1151 is located at the portion of the first connecting rod 1111 away from the cover 1101, and the second gear 1152 is located at the portion of the second connecting rod 1112 away from the cover 1101. The third gear 1153 is located between the first gear 1151 and the second gear 1152. The third gear 1153 is pivotally connected to the housing and meshes with the first gear 1151 and the second gear 1152 , and is capable of transmitting the rotational motion of the first gear 1151 to the second gear 1152 .

[0095] In this embodiment, the distal end 1128 of the first lower connecting portion 1124 is connected to a power device (not shown in the figure) via a shaft, and the distal end 1129 of the second lower connecting portion 1125 is pivotally connected to the housing via a shaft.

[0096] When the power device rotates, the power device drives the first connecting rod 1111 to rotate around the distal end 1128 of the first lower connecting part 1124. When the first connecting rod 1111 rotates, the first gear 1151 rotates synchronously. The first gear 1151 drives the third gear 1153 to rotate, and the third gear 1153 drives the second gear 1152 to rotate. The second gear 1152 is fixedly connected to the second connecting rod 1112, so that the second connecting rod 1112 and the second gear 1152 rotate together. That is, the rotation of the first connecting rod 1111 is transmitted to the second connecting rod 1112 through the gear set 1145. The gear set 1145 is arranged at the distal end 1128 of the first lower connecting part 1124 and the distal end 1129 of the second lower connecting part 1125, which is conducive to transmitting the movement of the first connecting rod 1111 to the second connecting rod 1112 as soon as possible, so that the first connecting rod 1111 and the second connecting rod 1112 rotate together.

[0097] Fig. 11B shows the closed position of the lid, Fig. 11CThe open position of the cover is shown. When the cover moves from the closed position to the open position, the driving device drives the first connecting rod 1111 to rotate in the clockwise direction as shown by the arrow, the first gear 1151 fixedly connected to the first connecting rod 1111 rotates in the clockwise direction, the third gear 1153 meshed with the first gear 1151 rotates in the counterclockwise direction, the second gear 1152 meshed with the third gear 1153 rotates in the clockwise direction, and the second connecting rod 1112 fixedly connected to the second gear rotates in the clockwise direction. The first connecting rod 1111 and the second connecting rod 1112 rotate together to move the cover 1101 to the open position. When the cover 1101 needs to be closed, the driving device drives the first connecting rod 1111 to rotate counterclockwise to return from the open position to the closed position.

[0098] and Fig. 10A Compared with the embodiment shown in FIG. 1 , the rotational motion of the first connecting rod 1111 is transmitted by the gear set 1045 in this embodiment, so as to achieve the same Fig. 10A In the embodiment, the third gear in the gear set 1045 can be a plurality of gears, and the plurality of gears can mesh with each other to transmit the rotational motion of the first gear 1151 to the second gear 1152 .

[0099] In the present application, the transmission device is composed of rigid parts, has high strength, and is not prone to elastic deformation, thereby ensuring the transmission stability to the greatest extent, so that the assembly system is not prone to shaking during the process of opening or closing the cover.

[0100] In the present application, the transmission device may also be other devices capable of transmitting the rotational motion of the first connecting rod to the second connecting rod.

[0101] In another embodiment of the present application, the first connecting rod and the second connecting rod are made of a material with high strength, such as metal or metal insert injection molding. In the absence of a transmission device, the first connecting rod and the second connecting rod are not easily deformed during the rotation process, so that the connecting rod mechanism and the cover are not easily shaken during the process of opening or closing the cover.
