Charging sockets and electric vehicles

Abstract

This utility model discloses a charging socket for an electric vehicle and an electric vehicle including the charging socket. The charging socket includes: a bracket with a charging port that protrudes beyond the bracket in a first direction opposite to the electric vehicle; a seal disposed on the outer wall of the port protruding beyond the bracket; and a cover for covering the port to form a sealing contact with the seal. Because the port protrudes beyond the bracket in a first direction opposite to the electric vehicle, water or other liquids on the surface of the bracket are less likely to enter the port after the bracket is installed on the electric vehicle. Instead, they flow downwards under gravity along the part of the port that contacts the bracket, which facilitates a good seal between the cover and the port.

Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, and more specifically to a charging socket and an electric vehicle. Background Technology

[0002] Electric vehicle charging sockets typically have a certain level of waterproof sealing for their charging ports and dust covers. In addition to preventing dust, the dust cover also provides better waterproof protection during charging or when the vehicle is submerged in water, ensuring charging safety.

[0003] However, the current domestic electric vehicle charging sockets use direct-plug dust covers that have a low waterproof rating when used with the charging port. This not only fails to meet the waterproof rating requirements for vehicles that need to wade through water, but also fails to meet the waterproof rating requirements for some high-end models.

[0004] In addition, the current domestic electric vehicle charging sockets have low waterproof ratings for flip-type dust covers that work with the charging ports. Achieving a higher waterproof rating requires complex design, which results in more parts, more complex assembly, higher cost, and lower reliability for flip-type dust covers.

[0005] The present invention aims to provide a charging socket with a high waterproof rating, simple structure, low cost and high reliability. Utility Model Content

[0037] See Figures 1 to 12This utility model discloses a charging socket 1000 and 2000 for electric vehicles (not shown in the figure) and an electric vehicle including the charging socket 1000 and 2000.

[0038] Figures 1 to 6 A charging socket 1000 according to a first embodiment of the present invention is shown. The charging socket 1000 includes a first bracket 100, a first sealing member 300, and a first cover 600. The first bracket 100 is provided with a first port 110 for charging, the first port 110 protruding beyond the first bracket 100 in a first direction D1 away from the electric vehicle. This makes it less likely for water or other liquids on the surface of the first bracket 100 to enter the first port 110 after the first bracket 100 is installed on the electric vehicle. Instead, the liquids flow downwards under gravity along the portion where the first port 110 contacts the first bracket 100, facilitating a good seal between the first cover 600 and the first port 110, as described below. The first sealing member 300 is provided at a distance L1 beyond the first bracket 100 from the first port 110 (see [reference]). Figure 6 On the first outer wall 111 of ).

[0039] The first cover 600 is used to cover the first port 110, which protrudes beyond the first bracket 100, to form a sealing contact with the first seal 300. Partly because water or other liquids located on the surface of the first bracket 100 are less likely to enter the first port 110, the charging socket 1000 not only meets the waterproof rating requirements for wading vehicles but also for some high-end models. The charging socket 1000 achieves a high waterproof rating with a simple structure, offering both low cost and high reliability. Although... Figure 6 A first seal 300 is shown, but those skilled in the art should understand that the number of first seals 300 is not limited to this, and the distance L1 can be changed according to actual needs so that multiple first seals 300 can be provided on the first outer wall 111 to achieve a higher level of waterproofing.

[0040] See Figure 2 , 35 and 6, the first port 110 has a first groove 1111 extending circumferentially on its first outer wall 111 protruding beyond the first bracket 100 for receiving the first seal 300. The first port 110 includes a first sub-port 1101 and a second sub-port 1102 communicating with each other, wherein the first sub-port 1101 is used for AC slow charging, and the first sub-port 1101 and the second sub-port 1102 together are used for DC fast charging. The first sub-port 1101 receives seven first terminals 11011 for AC slow charging, and the second sub-port 1102 receives two second terminals 11021 for DC fast charging together with the seven first terminals 11011. See also Figure 6 The first seal 300 is provided with two first ridges 310 extending circumferentially and spaced apart from each other. The two first ridges 310 are in direct contact with and pressed by the first cover 600 covering the first port 110 to form a good seal between the first cover 600 and the first port 110. However, those skilled in the art should understand that the number of first ridges 310 is not limited to two. The first ridges 310 can also be one (corresponding to a lower waterproof rating) or three or more (corresponding to a higher waterproof rating) to meet different waterproof rating requirements.

[0041] Figures 7 to 12 A charging socket 2000 according to a second embodiment of the present invention is shown. The charging socket 2000 includes: a second bracket 200, a second sealing member 400, a third sealing member 500, a second cover 700, and a third cover 800. The second bracket 200 is provided with a second port 210 and a third port 220, which are separate from each other for charging. The second port 210 is used for AC slow charging, and the third port 220 is used for DC fast charging. See also... Figure 8 and 9 The second port 210 accommodates seven third terminals 212 for AC slow charging, and the third port 220 accommodates nine fourth terminals 222 for DC fast charging.

[0042] The second port 210 protrudes beyond the second bracket 200 along a first direction D1 opposite to the electric vehicle, and the third port 220 protrudes beyond the second bracket 200 along the same first direction D1 opposite to the electric vehicle. A second seal 400 is disposed on the second outer wall 211 of the second port 210 protruding beyond the second bracket 200, and a third seal 500 is disposed on the third outer wall 221 of the third port 220 protruding beyond the second bracket 200. Specifically, see... Figures 7 to 12The second bracket 200 is provided with a boss 201 that protrudes beyond the second bracket 200 along the first direction D1. The second port 210 and the third port 220 are provided on the boss 201 and protrude beyond the boss 201 along the first direction D1. This makes it less likely for water or other liquids on the surface of the second bracket 200 to enter the second port 210 and the third port 220 relative to the first bracket 100 after the second bracket 200 is installed on the electric vehicle. Instead, under the action of gravity, the liquids flow downward along the parts where the boss 201 contacts the second bracket 200 and the parts where the second port 210 and the third port 220 contact the boss 201. This facilitates the formation of a good seal between the second cover 700 and the second port 210 and between the third cover 800 and the third port 220, as described below.

[0043] The second seal 400 is positioned at the second port 210, protruding beyond the boss 201 by a distance L2 (see [reference]). Figure 12 On the second outer wall 211 of the second port 210, a second groove 2111 extending circumferentially is provided on the second outer wall 211 that protrudes beyond the boss 201 (see...). Figure 9 ), to accommodate the second seal 400.

[0044] The third seal 500 is positioned at the third port 220, protruding beyond the boss 201 by a distance L3 (see [reference]). Figure 12 On the third outer wall 221 of the third port 220, a third groove 2211 extending circumferentially is provided on the third outer wall 221 that protrudes beyond the boss 201 (see...). Figure 9 ), to accommodate the third seal 500.

[0045] The second cover 700 covers the second port 210, which protrudes beyond the boss 201, to form a sealing contact with the second seal 400, and the third cover 800 covers the third port 220, which protrudes beyond the boss 201, to form a sealing contact with the third seal 500. Partly due to the fact that water or other liquids located on the surface of the second bracket 200 are less likely to enter the second port 210 and the third port 220, the charging socket 2000 not only meets the waterproof rating requirements for wading vehicles but also for some high-end models. The charging socket 2000 achieves a high waterproof rating with a simple structure, and is not only inexpensive but also highly reliable. Although... Figure 12The diagram shows a second seal 400 and a third seal 500. However, those skilled in the art should understand that the number of the second seal 400 and the third seal 500 is not limited to this. The distance L2 can be changed according to actual needs to provide multiple second seals 400 on the second outer wall 211 and the distance L3 can be changed to provide multiple third seals 500 on the third outer wall 221 to achieve a higher level of waterproofing.

[0046] The second seal 400 is provided with two second ridges 410 extending circumferentially and spaced apart from each other. The two second ridges 410 are in direct contact with and pressed by the second cover 700 covering the second port 210 to form a good seal between the second cover 700 and the second port 210. The third seal 500 is provided with two third ridges 510 extending circumferentially and spaced apart from each other. The two third ridges 510 are in direct contact with and pressed by the third cover 800 covering the third port 220 to form a good seal between the third cover 800 and the third port 220. However, those skilled in the art should understand that the number of second ridges 410 and third ridges 510 is not limited to two. There may be one second ridge 410 and one third ridge 510 (corresponding to a lower waterproof rating) or three or more (corresponding to a higher waterproof rating) to accommodate different waterproof rating requirements.
