Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. CN202420933496.7, filed on April 30, 2024, the entire disclosure of which is incorporated herein by reference.

[0002] The present disclosure relates to the field of new energy, and more particularly to a dust cover for a charging dock of an electric vehicle and an electric vehicle. [Background technology]

[0003] Existing electric vehicle dust covers are secured to the DC or AC charging port by interfering the outer wall of the dust cover with the inner wall of the DC or AC charging port.

[0004] However, this interference is achieved by interference ribs arranged on the outer wall of the dust cover, which increases the diameter of the outer wall of the dust cover. The inside of the dust cover is hollow and is prone to deformation after long-term insertion and removal. In addition, the dust cover is prone to shrinkage in northern regions where the temperature is too low, which affects the insertion and removal force of the dust cover.

[0005] Additionally, the pull rope of existing dust covers is integrally formed with the dust cover, and due to molding limitations, the pull rope can only extend from the periphery of the dust cover, limiting the twisting space of the pull rope.

[0006] Therefore, there is a need to provide a dust cover for an electric vehicle charging dock that has a high insertion / extraction force, is resistant to deformation, and has a large torsion space for the pull rope. Summary of the Invention [Problem to be solved by the invention]

[0034] The present disclosure discloses a dust cover 1000 (see FIGS. 1 to 8 ) for a charging dock 2000 of an electric vehicle (not shown in FIGS. 1 to 8 ), and an electric vehicle including the dust cover 1000. The charging dock 2000 includes a DC charging port 2100 and an AC charging port 2200. The dust cover 1000 includes a main body 1100, a boss 1200, and fixing portions 1300, 1400, and 1500. For ease of explanation, in the following description, fixing portion 1300 will also be referred to as the first fixing portion, fixing portion 1400 as the second fixing portion, and fixing portion 1500 as the third fixing portion.

[0035] The main body 1100 is configured to have a peripheral contour 1110 that matches the contour of the inner wall 2101 of the DC charging port 2100, and therefore the peripheral contour 1110 matches the shape of the inner wall 2101 of the DC charging port 2100 (see FIG. 8), and when the DC charging port 2100 is covered with the dust cover 1000 (see FIG. 4), the outer surface of the main body 1100 adjacent to the peripheral contour 1110 is flush with the outer surface of the charging dock 2000 adjacent to the DC charging port 2100.

[0036] The boss 1200 is provided on the inner surface of the main body 1100 facing the DC charging port 2100 and is configured to have a peripheral contour 1210 (see FIG. 3) that matches the contour of the inner wall 2201 (see FIG. 6) of the AC charging port 2200. Therefore, the peripheral contour 1210 matches the shape of the inner wall 2201 of the AC charging port 2200, and when the AC charging port 2200 is covered with the dust cover 1000, the outer surface of the charging dock 2000 adjacent to the AC charging port 2200 is covered by the outer surface of the main body 1100 adjacent to the peripheral contour 1110 (see FIG. 4).

[0037] Fixing portions 1300, 1400, and 1500 are provided on boss 1200, protrude from boss 1200, and include at least one interference rib 1311, 1411, 1511, 1321, 1323, and 1421 (see FIGS. 3, 5 to 8), respectively. As will be described in further detail below, at least one interference rib 1311, 1411, 1511, 1321, 1323, and 1421 is configured to interfere with corresponding terminals of DC charging port 2100 and / or AC charging port 2200 when dust cover 1000 is covered by dust cover 1000, thereby fixing dust cover 1000 to DC charging port 2100 and / or AC charging port 2200. By providing fixing portions 1300, 1400, and 1500 on the inner surface of main body 100, dust cover 1000 is fixed to DC charging port 2100 and / or AC charging port 2200, which avoids placing dust cover 1000 in a hollow space to interfere with DC charging port 2100 and / or AC charging port 2200, increases the rigidity of dust cover 1000, makes dust cover 1000 less likely to deform after long-term insertion and removal, and ensures the insertion and removal force of the dust cover.

[0038] 3 , the fixing portions 1300, 1400, and 1500 include first belt-like projections 1310, 1410, and 1510 extending along a V-shaped contour, and second belt-like projections 1320, 1420, and 1520 extending at least partially along the peripheral contour 1210 of the boss 1200 so as to connect between two ends of the first belt-like projections 1310, 1410, and 1510 to form a closed shape, thereby increasing the rigidity of the fixing portions 1300, 1400, and 1500. At least one of the first belt-like projections 1310, 1410, and 1510 and the second belt-like projections 1320, 1420, and 1520 includes at least one interference rib 1311, 1411, 1511, 1321, 1323, and 1421.

[0039] 1, 5, and 6, AC charging port 2200 includes a first AC terminal 2210, an AC ground terminal 2220, and a neutral terminal 2230 arranged in sequence along a straight line, an AC check terminal 2240 and a control terminal 2250 arranged in a straight line on one side of first AC terminal 2210, AC ground terminal 2220, and neutral terminal 2230, and a second AC terminal 2260 and a third AC terminal 2270 arranged in a straight line on the other side of first AC terminal 2210, AC ground terminal 2220, and neutral terminal 2230.

[0040] 3 and 6, first belt-like projections 1310, 1410, and 1510 are configured such that upper portions 1312 of two first belt-like projections 1310 abut against upper ends of AC confirmation terminal 2240 and control terminal 2250 of AC charging port 2200, respectively, upper portion 1412 of first belt-like projection 1410 abuts against an upper end of third AC terminal 2270 of AC charging port 2200, and upper portion 1512 of first belt-like projection 1510 abuts against an upper end of second AC terminal 2260 of AC charging port 2200, thereby fixing the position of dust cover 1000 on AC charging port 2200 and preventing dust cover 1000 from being excessively inserted into AC charging port 2200.

[0041] 3 and 6, boss 1200 includes an interference rib 1220 extending from the peripheral contour of boss 1200 on the side of second belt-like projections 1320, 1420, 1520 facing away from first belt-like projections 1310, 1410, 1510. Interference rib 1220 is configured to interfere with the inner wall of AC charging port 2200 when AC charging port 2200 is covered with dust cover 1000, thereby further securing dust cover 1000 to AC charging port 2200.

[0042] 3 and 5, second belt-shaped projection 1320 of first fixing portion 1300 is configured to protrude beyond first belt-shaped projection 1310 of first fixing portion 1300, and second belt-shaped projection 1320 of first fixing portion 1300 includes a bent portion 1322 that bends toward one end of first belt-shaped projection 1310 to form second belt-shaped projection 1320 in an angle shape. Bent portion 1322 is configured to be disposed near or abut against a side surface of AC confirmation terminal 2240 or control terminal 2250 when upper portion 1312 of first belt-shaped projection 1310 abuts against the upper end of AC confirmation terminal 2240 or control terminal 2250 (see FIG. 5), thereby helping to accurately position dust cover 1000 on AC charging port 2200.

[0043] 3, 5, and 6, second belt-shaped projection 1320 of first fixing portion 1300 includes first interference rib 1321 at an end of second belt-shaped projection 1320 away from bent portion 1322. First interference rib 1321 is configured to abut against an upper end of AC confirmation terminal 2240 or control terminal 2250 at upper portion 1312 of first belt-shaped projection 1310 (see FIG. 6). When second belt-shaped projection 1320 is disposed between AC confirmation terminal 2240 or control terminal 2250 and inner wall 2201 of AC charging port 2200 (see FIG. 5), second belt-shaped projection 1320 interferes with AC confirmation terminal 2240 or control terminal 2250 to further secure dust cover 1000 to AC charging port 2200.

[0044] 3, 5, and 6, second belt-shaped projection 1420 of second fixing portion 1400 is configured to protrude beyond first belt-shaped projection 1410 of second fixing portion 1400 and includes second interference rib 1421. Second interference rib 1421 is configured to interfere with third AC terminal 2270 (see FIG. 5) when upper portion 1412 of first belt-shaped projection 1410 abuts against the upper end of third AC terminal 2270 (see FIG. 6) and second belt-shaped projection 1420 is disposed between third AC terminal 2270 and inner wall 2201 of AC charging port 2200 (see FIGS. 5 and 6), thereby further fixing dust cover 1000 to AC charging port 2200.

[0045] 3, 5, and 6, the fixing portion also includes a third fixing portion 1500. An upper portion of second belt-like projection 1520 of third fixing portion 1500 is flush with an upper portion 1512 of first belt-like projection 1510 of third fixing portion 1500; therefore, second belt-like projection 1520 does not form an interference fit between second AC terminal 2260 and inner wall 2201 of AC charging port 2200, making it easier to remove dust cover 1000 from AC charging port 2200. The first belt-shaped protrusion 1510 of the third fixing portion 1500 is configured so that when the AC charging port 2200 is covered with the dust cover 1000, the upper portion 1512 of the first belt-shaped protrusion 1510 abuts against the upper end of the second AC terminal 2260 (see FIG. 6), thereby preventing the dust cover 1000 from being excessively inserted into the AC charging port 2200.

[0046] 1 , DC charging port 2100 includes first DC terminal 2110 and second DC terminal 2120 arranged along a straight line. Dust cover 1000 is configured such that when DC charging port 2100 is covered with dust cover 1000, bosses 1200 abut against the upper ends of first DC terminal 2110 and second DC terminal 2120 to prevent dust cover 1000 from being excessively inserted into DC charging port 2100. In FIGS. 7 and 8 , bosses 1200 abutting the upper ends of first DC terminal 2110 and second DC terminal 2120 are hidden to show the relative positions of the terminals of DC charging port 2100 and fixing portions 1300, 1400, and 1500.

[0047] 1, DC charging port 2100 further includes first communication terminal 2130, second confirmation terminal 2140, and second communication terminal 2150, which are arranged in sequence along a straight line on one side of first DC terminal 2110 and second DC terminal 2120. The two first fixing portions 1300 are configured such that when DC charging port 2100 is covered with dust cover 1000, the upper portions of second belt-shaped protrusions 1320 of first fixing portion 1300 abut against the upper ends of first communication terminal 2130 and second communication terminal 2150, respectively (see FIG. 7), thereby preventing dust cover 1000 from being excessively inserted into DC charging port 2100.

[0048] 3, 7, and 8, first belt-shaped projection 1310 of first fixing portion 1300 includes third interference rib 1311, and bent portion 1322 includes fourth interference rib 1323 at an end of first fixing portion 1300 remote from first belt-shaped projection 1310. Third interference rib 1311 and fourth interference rib 1323 are configured to interfere with first DC terminal 2110 or second DC terminal 2120 when DC charging port 2100 is covered with dust cover 1000, thereby fixing dust cover 1000 to DC charging port 2100.

[0049] 1 , DC charging port 2100 further includes first auxiliary terminal 2160, DC ground terminal 2170, and second auxiliary terminal 2180 arranged in this order along a straight line on the other side of first DC terminal 2110 and second DC terminal 2120. First belt-shaped projection 1410 of second fixing portion 1400 includes fifth interference rib 1411 (see FIGS. 3 , 7 , and 8 ). Therefore, when DC charging port 2100 is covered with dust cover 1000, first belt-shaped projection 1410 of second fixing portion 1400 is tightly fitted between first DC terminal 2110 and DC ground terminal 2170 by fifth interference rib 1411. The second fixing portion 1400 is configured so that when the DC charging port 2100 is covered with the dust cover 1000, the upper portion of the second belt-shaped protrusion 1420 of the second fixing portion 1400 abuts against the upper end of the first auxiliary terminal 2160, thereby preventing the dust cover 1000 from being excessively inserted into the DC charging port 2100.

[0050] 3, 7, and 8, the first belt-like protrusion 1510 of the third fixing portion 1500 includes a sixth interference rib 1511, so that when the DC charging port 2100 is covered with the dust cover 1000, the first belt-like protrusion 1510 of the third fixing portion 1500 is in an interference fit between the second DC terminal 2120 and the DC ground terminal 2170 by the sixth interference rib 1511, thereby further fixing the dust cover 1000 to the DC charging port 2100.

[0051] 1, DC charging port 2100 further includes a first confirmation terminal 2190, which is disposed between second confirmation terminal 2140 and DC ground terminal 2170, is aligned with second confirmation terminal 2140 and DC ground terminal 2170, and is disposed on the side of first DC terminal 2110 and second DC terminal 2120. A portion of first belt-shaped protrusion 1310 of first fixing portion 1300 facing away from first DC terminal 2110 or second DC terminal 2120 abuts first confirmation terminal 2190 (see FIG. 7 ), further fixing dust cover 1000 to DC charging port 2100.

[0052] 3, the boss 1200 has a groove 1600 on its axis of symmetry. A portion of the first belt-like protrusion 1310 of the first fixing part 1300 facing away from the first DC terminal 2110 or the second DC terminal 2120 is connected to and is flush with a side wall 1610 of the groove 1600. The provision of the groove 1600 ensures that the entire dust cover 1000 has the same thickness, i.e., that the main body 1100 and the groove 1600 of the boss 1200 have the same thickness in a cross section taken in a direction perpendicular to the charging dock 2000.

[0053] 3, the dust cover 1000 includes two first fixing portions 1300 arranged symmetrically on either side of the groove 1600 at one end of the groove 1600, and a second fixing portion 1400 and a third fixing portion 1500 arranged symmetrically on either side of the groove 1600 at the other end of the groove 1600. However, this is not limiting, and it should be understood by those skilled in the art that the number and relative positions of the first fixing portions 1300, second fixing portions 1400, and third fixing portions 1500 can be set as needed.

[0054] 2, the dust cover 1000 is provided with a pull rope () 1700, one end 1710 of which is removably attached to the bottom wall of the groove 1600 on the side facing away from the charging dock 2000, and the other end 1720 of which is removably attached to the charging dock 2000. By providing the pull rope 1700 in a detachable manner, the pull rope can have a large twisting space.

[0055] The embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings.
