[0028] See Figures 1 to 6This utility model discloses a charging base 1000 for electric vehicles and a cable assembly (not shown in the figure) including the charging base 1000 and a cable connected to the charging base 1000.

[0029] The charging dock 1000 includes: a housing 100, a first cover 200, a second cover 300, a magnetic component 400, and a metal component 500. The magnetic component 400 includes, but is not limited to, a neodymium iron boron magnet. The housing 100 is provided with a first port 110 for accommodating AC charging terminals and a second port 120 for accommodating DC charging terminals. The first port 110 has a first protrusion 112 on its inner wall 111, and the second port 120 has a second protrusion 122 on its inner wall 121 (see...). Figure 2 and 3 ).

[0030] See Figure 4 The first cover 200 is mounted on the first port 110 and has two first lugs 210 on opposite sides thereon. One of the magnetic element 400 and the metal element 500 is disposed on one of the two first lugs 210. The other of the magnetic element 400 and the metal element 500 is disposed on the top surface 1121 of the first boss 112 and protrudes from the top surface 1121 (see [link]). Figure 2 and 3 The two first lugs 210 have grooves 211 on the side facing the first boss 112 for receiving one of the magnetic element 400 and the metal element 500. The side of the first lug 210 facing the first boss 112 is configured to fit the shape of the top surface 1121 of the first boss 112 so that the first cover 200 is installed in the first port 110 and forms an abutment between the magnetic element 400 and the metal element 500.

[0031] although Figure 4 An embodiment is shown with two first lugs 210 and a groove 211 provided on each first lug 210. However, those skilled in the art should understand that the present invention is not limited thereto. The number of first lugs 210 can be one or more, and multiple grooves 211 can be provided on each first lug 210, with the number of grooves 211 on each first lug 210 being the same or different. The groove 211 is configured to have a depth that allows the magnetic element 400 and the metal element 500 to abut within the groove 211, that is, the magnetic element 400 and the metal element 500 to contact within the groove 211, such that the groove 211 limits the magnetic element 400 and the metal element 500, thereby preventing displacement between the magnetic element 400 and the metal element 500.

[0032] See Figure 5The second cover 300 is mounted on the second port 120 and has two second lugs 310 on opposite sides thereon. One of the magnetic element 400 and the metal element 500 is disposed on one of the two second lugs 310. The other of the magnetic element 400 and the metal element 500 is disposed on the top surface 1221 of the second boss 122 and protrudes from the top surface 1221 to form an abutment between the magnetic element 400 and the metal element 500. The second lug 310 has a groove 311 on the side facing the second boss 122 for receiving one of the magnetic element 400 and the metal element 500. The side of the second lug 310 facing the second boss 122 is configured to fit the shape of the top surface 1221 of the second boss 122 so that the second cover 300 is mounted in the second port 120 and forms an abutment between the magnetic element 400 and the metal element 500.

[0033] although Figure 5 An embodiment is shown with two second lugs 310 and a groove 311 provided on each second lug 310. However, those skilled in the art should understand that the present invention is not limited thereto. The number of second lugs 310 may be one or more, and multiple grooves 311 may be provided on each second lug 310. The number of grooves 311 on each second lug 310 may be the same or different. The groove 311 is configured to have a depth in which the magnetic element 400 and the metal element 500 abut against each other (see [reference]). Figure 6 That is, the magnetic component 400 and the metal component 500 come into contact within the groove 311, so that the groove 311 limits the magnetic component 400 and the metal component 500, thereby preventing the magnetic component 400 and the metal component 500 from shifting.

[0034] A magnetic component 400 can be disposed on one of the first protrusion 112 and the first cover 200, and a metal component 500 is correspondingly disposed on the other of the first protrusion 112 and the first cover 200, such that the first cover 200 is mounted on the first port 110 with the assistance of the magnetic attraction between the magnetic component 400 and the metal component 500. For the sake of brevity, Figure 2 , 3 Figures 6 and 7 only show an embodiment where the magnetic element 400 is disposed on the first cover 200 and the metal element 500 is correspondingly disposed on the first boss 112. More specifically, the magnetic element 400 is disposed in the groove 211 of each of the two first lugs 210. Two first bosses 112 are respectively disposed on opposite sides of the inner wall 111 of the first port 110. Although Figure 2 , 3Figures 6 and 7 illustrate an embodiment with two first protrusions 112 and a metal piece 500 disposed on each first protrusion 112. However, those skilled in the art should understand that the present invention is not limited thereto. The number of first protrusions 112 may be one or more, and multiple metal pieces 500 may be disposed on each first protrusion 112. The number of metal pieces 500 on each first protrusion 112 may be the same or different. The first cover 200 is provided with multiple corresponding magnetic pieces 400 at corresponding positions, such that when the first cover 200 is installed on the first port 110, the multiple magnetic pieces 400 correspond one-to-one with the multiple metal pieces 500 and are aligned with each other.

[0035] The one-to-one correspondence and alignment of the magnetic component 400 and the metal component 500 on the first cover 200 and the first port 110 allows the first cover 200 to be more firmly installed on the first port 110 by magnetic attraction. It also ensures that there is a certain holding force between the first cover 200 and the first port 110 when the first cover 200 is inserted into the first port 110 and when it is pulled out of the first port 110. There is no need to install a sealing ring on the side wall of the first cover 200 to achieve an interference fit between the sealing ring and the side wall of the first port 110 to obtain this holding force. This avoids the deformation of the first cover 200 or the wear of the sealing ring after long-term insertion and removal due to such interference fit. It eliminates the need for periodic replacement of the first cover 200 or the sealing ring, reduces the use cost of the charging base 1000 and the electric vehicle, and improves the durability of the charging base 1000.

[0036] A magnetic component 400 can be disposed on one of the second protrusion 122 and the second cover 300, and a metal component 500 is correspondingly disposed on the other of the second protrusion 122 and the second cover 300, such that the second cover 300 is mounted on the second port 120 with the assistance of the magnetic attraction between the magnetic component 400 and the metal component 500. For the sake of simplicity, Figure 2 , 3 Figures 6 and 7 only show an embodiment where the magnetic element 400 is disposed on the second cover 300 and the metal element 500 is correspondingly disposed on the second boss 122. More specifically, the magnetic element 400 is disposed in the groove 311 of each of the two second lugs 310. Two second bosses 122 are respectively disposed on opposite sides of the inner wall 121 of the second port 120. Although Figure 2 , 3Figures 6 and 7 illustrate an embodiment with two second protrusions 122 and a metal element 500 disposed on each second protrusion 122. However, those skilled in the art should understand that the present invention is not limited thereto. The number of second protrusions 122 may be one or more, and multiple metal elements 500 may be disposed on each second protrusion 122. The number of metal elements 500 on each second protrusion 122 may be the same or different. The second cover 300 is provided with multiple corresponding magnetic elements 400 at corresponding positions, such that when the second cover 300 is installed on the second port 120, the multiple magnetic elements 400 correspond one-to-one with the multiple metal elements 500 and are aligned with each other (see Figure 6). Figure 6 ).

[0037] The one-to-one correspondence and alignment of the magnetic component 400 and the metal component 500 on the second cover 300 and the second port 120 allows the second cover 300 to be more firmly installed on the second port 120 by magnetic attraction. It also ensures a certain holding force between the second cover 300 and the second port 120 when the second cover 300 is inserted into and removed from the second port 120. This eliminates the need to install a sealing ring on the side wall of the second cover 300 to achieve an interference fit between the sealing ring and the side wall of the second port 120 to obtain this holding force. This avoids the deformation of the second cover 300 or wear of the sealing ring after long-term insertion and removal due to such interference fit. It also eliminates the need for periodic replacement of the second cover 300 or the sealing ring, reduces the operating cost of the charging base 1000 and the electric vehicle, and improves the durability of the charging base 1000.
