Technical Field

[0001] This invention is applicable to the automotive field, and in particular relates to a charging port structure and an electric vehicle. Background Technology

[0002] Electric vehicles generally have two charging modes: fast charging and slow charging. Correspondingly, electric vehicles have two types of charging interfaces: a fast charging interface for fast charging and a slow charging interface for slow charging. Charging guns are connected to these two interfaces to charge the electric vehicle, enabling both charging modes. Each charging interface has a cover to protect it from dust and water.

[0003] In existing technologies, fast charging ports and slow charging ports are usually arranged on the same plane, resulting in large opening areas on the vehicle body, taking up space, and being unsightly. At the same time, each port requires an independent charging port cover, which is structurally complex and increases product costs. Summary of the Invention

[0006] Firstly, a charging port structure includes:

[0007] The charging port holder is equipped with a first charging interface;

[0008] The charging port cover has a second charging port.

[0009] When the charging port cover is closed, the first charging interface is fastened towards the second charging interface, the first charging interface blocks the second charging interface, and the second charging interface blocks the first charging interface; when the charging port cover is open, the first charging interface and the second charging interface are opened to the charging state.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the charging port cover is connected to the charging port base via a hinge, the hinge defining a rotation axis for opening or closing the charging port cover, and the first charging interface and the second charging interface are arranged mirror images of each other relative to the rotation axis.

[0011] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the charging port has a first end face, the first end face is provided with a first enclosure wall, the first enclosure wall protrudes from the first end face along the insertion direction of the first charging interface, the interior of the first enclosure wall defines a first insertion cavity, and the first charging interface is disposed in the first insertion cavity.

[0012] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the charging port cover has a second end face, which faces the first end face when the charging port cover is closed. The second end face is provided with a base, and the base is provided with a second enclosure wall. The second enclosure wall protrudes from the second end face along the insertion direction of the second charging interface. The interior of the second enclosure wall defines a second insertion cavity, and the second charging interface is disposed in the second insertion cavity. The second enclosure wall is embedded in the first insertion cavity when the charging port cover is closed.

[0013] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the outer peripheral surface of the second enclosure is provided with a flange, which can match and fit with the inner wall of the first insertion cavity when the second enclosure is embedded in the first insertion cavity.

[0014] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the base surface is provided with a sealing ring that mates with the end face of the first enclosure when the second enclosure is embedded in the first insertion cavity.

[0015] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the outer side of the first enclosure is provided with a locking buckle on the side away from the hinge, and the base is provided with a locking tongue for cooperating with the locking buckle on the side away from the hinge.

[0016] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the base is detachably mounted on the second end face of the charging port cover, the base has a socket on the back side of the second charging interface, the base has a cable, the cable is connected to the second charging interface and the socket, and the charging port structure further includes a winding component for winding the cable.

[0017] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, a groove is provided on the second end face of the charging port cover, one end of the groove extends to the edge of the charging port cover, and the other end of the groove extends to the front end of the edge of the charging port cover. The base is provided with a slider, and the slider is detachably mounted on the groove.

[0018] In a second aspect, an electric vehicle includes the charging port structure described in any implementation of the first aspect.

In the description of this invention, the terms "first" and "second" are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In this invention, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention based on the specific content of the technical solution.

[0031] See Figure 1 , Figure 2 The present invention provides a charging port structure, including a charging port base 100 and a charging port cover 200. The charging port base 100 is provided with a first charging interface 101; the charging port cover 200 is provided with a second charging interface 201; the first charging interface 101 and the second charging interface 201 can be specifically configured as a fast charging interface and a slow charging interface, for example, the first charging interface 101 is configured as a fast charging interface and the second charging interface 201 is configured as a slow charging interface.

[0032] The charging port holder 100 can be directly installed on the vehicle body structure using fasteners, while the charging port cover 200 can be closed or opened. When the charging port cover 200 is closed, the first charging port 101 is fastened towards the second charging port 201, with the first charging port 101 blocking the second charging port 201, and the second charging port 201 blocking the first charging port 101; when the charging port cover 200 is open, both the first charging port 101 and the second charging port 201 are opened to a charging state.

[0033] Combination Figure 1 , Figure 2In the technical solution of this invention, a first charging interface 101 is disposed on a charging port holder 100, and a second charging interface 201 is disposed on a charging port cover 200. When the charging port cover 200 is opened, the first charging interface 101 and the second charging interface 201 are opened to a charging state, forming two charging interfaces, namely a fast charging interface and a slow charging interface. When charging is not required, the charging port cover 200 is closed, and the first charging interface 101 is fastened towards the second charging interface, achieving dustproof and waterproof protection. The technical solution of this invention abandons the traditional method of setting charging interfaces only on the charging port holder 100. By stacking the fast and slow charging ports together, it has the following advantages: 1. It saves space, reduces the opening area of ​​the vehicle body, and makes the vehicle appearance neat and beautiful; 2. It reduces some parts, such as reducing a charging port sealing cover, saving costs; 3. The second charging interface 201 is directly disposed on the charging port cover 200, which is conducive to heat dissipation during charging.

[0034] In some embodiments, see Figure 1 , Figure 2 The charging port cover 200 is connected to the charging port base 100 via a hinge 300. The hinge 300 defines the rotation axis of the charging port cover 200 for opening or closing, allowing the charging port cover 200 to rotate around the rotation axis to switch between an open and closed state. The first charging interface 101 and the second charging interface 201 are arranged mirror images of each other with respect to the rotation axis. In this embodiment, connecting the charging port cover 200 to the charging port base 100 via the hinge 300 has the following advantages: Firstly, the charging port cover 200 forms a structure that connects to the charging port base 100 and can be flipped outwards, facilitating opening and closing; secondly, the hinge 300 precisely defines the movement path of the charging port cover 200 during opening and closing, ensuring that the first charging interface 101 and the second charging interface 201 can accurately align and mutually shield each other when closed.

[0035] Further, see Figure 1 , Figure 2 The charging port holder 100 has a first end face 102, which faces the charging port cover 200 when the charging port cover 200 is closed. The first end face 102 is provided with a first enclosure 103, which protrudes from the first end face 102 along the insertion direction of the first charging interface 101. The interior of the first enclosure 103 defines a first insertion cavity 104, in which the first charging interface 101 is disposed. When charging through the first charging interface 101, the charging gun can be inserted into the first insertion cavity 104. With the guiding effect of the first enclosure 103, the charging gun and the first charging interface 101 are accurately matched, ensuring the stability of the connection.

[0036] See Figure 1 , Figure 2The charging port cover 200 has a second end face 202, which faces the first end face 102 when the charging port cover 200 is closed. The second end face 202 is provided with a base 203, and the base 203 is provided with a second enclosure 204. The second enclosure 204 protrudes from the second end face 202 along the insertion direction of the second charging interface. The interior of the second enclosure 204 defines a second insertion cavity 205. The second charging interface 201 is disposed in the second insertion cavity 205. When charging through the second charging interface 201, the charging gun can be inserted into the second insertion cavity 205. With the guidance of the second enclosure 204, the charging gun and the second charging interface 201 are accurately matched and the connection is stable.

[0037] The outer diameter of the second enclosure 204 is not greater than the inner diameter of the first enclosure 103. When the charging port cover 200 is closed, the second enclosure 204 is embedded in the first plug-in cavity 104, and they block each other to achieve functions such as dustproof and waterproof, and ensure the stability of the connection.

[0038] In order to ensure that the charging port cover 200 in the open state can provide stable back support for the second charging interface 201, a rubber block can be set on the back side of the charging port cover 200 in the open position as a support device.

[0039] Further, see Figure 2 The outer periphery of the second enclosure 204 is provided with a flange 206. The flange 206 extends continuously along the circumference of the second enclosure 204. When the second enclosure 204 is inserted into the first insertion cavity 104, the flange 206 can match and fit with the inner wall of the first insertion cavity 104, so as to achieve better dustproof and waterproof functions and further ensure the stability of the connection.

[0040] In some embodiments, see Figure 1 , Figure 2 The base 203 surface is provided with a sealing ring 207 that mates with the end face of the first enclosure 103 when the second enclosure 204 is embedded in the first insertion cavity 104. By setting the sealing ring 207, the sealing effect after the first charging interface 101 is fastened toward the second charging interface is improved, and better dustproof and waterproof functions are achieved.

[0041] In some embodiments, see Figure 1 , Figure 2The outer side of the first enclosure 103, away from the hinge 300, is provided with a locking buckle 105, and the base 203, also away from the hinge 300, is provided with a locking tongue 208 for engaging with the locking buckle 105. After the charging port cover 200 rotates and closes around the axis of rotation of the hinge 300, the locking tongue 208 engages with the locking buckle 105 and locks the charging port cover 200 in a stable closed state. The locking buckle 105 and the locking tongue 208, by means of the locking buckle 105 and the locking tongue 208, can confine the sealing ring 207 between the surface of the base 203 and the first enclosure 103 to a compressed state, thereby achieving better dustproof and waterproof functions.

[0042] In some embodiments, see Figures 1-4 The base 203 is detachably mounted on the second end face 202 of the charging port cover 200. The base 203 has a socket 209 on the back side of the second charging interface. The base 203 has a cable 210, which is connected to the second charging interface and the socket 209. The cable 210 is used to connect the second charging interface to the battery pack to store electricity in the battery pack. On the other hand, the cable 210 connects the battery pack to the socket 209 to discharge electricity to the outside. In other words, the cable 210 of the second charging interface can be pulled out and used as a wire. For example, the second charging interface can be pulled out and used as a portable power strip in the vehicle.

[0043] Among them, see Figure 2 The charging port structure also includes a cable winding component 400 for winding the cable 210. The cable winding component 400 can be a cable reel or a winding spool. The cable winding component 400 winds the cable 210 of a certain length by winding it up, realizing the cable retraction function. When the second charging port is pulled out and used as a portable power strip, the cable winding component 400 can release the cable 210, allowing the portable power strip to be pulled outward by a specific length according to the actual usage distance.

[0044] The base 203 can be detachably mounted to the charging port cover 200 using methods such as snap-fit, threads, or bolts. For example, in some embodiments, see [reference needed]. Figure 3 , Figure 4The charging port cover 200 has a sliding groove 211 on its second end face 202. The sliding groove 211 can be a dovetail groove or a trapezoidal groove. One end of the sliding groove 211 extends to the edge of the charging port cover 200, and the other end extends to the edge of the charging port cover 200 and ends thereafter. The base 203 has a slider 212, which is detachably mounted on the sliding groove 211. When the base 203 needs to be removed from the charging port cover 200 for use as a power bank, the base 203 can be slid outward along the sliding groove 211 and separate from the charging port cover 200 when it reaches the edge of the charging port cover 200. When reinstalling the base 203 back onto the charging port cover 200, the slider 212 of the base 203 can be aligned with the slide groove 211 and slid inwards. When it reaches the stop position of the slide groove 211, it connects with the charging port cover 200. The slide groove is vertically oriented, with its stop end located at the bottom. The base 203 automatically remains at the stop end of the slide groove under gravity. This embodiment uses the cooperation between the slider 212 and the slide groove 211 to achieve quick installation and removal of the base 203 from the charging port cover 200. The structure is simple, and installation and removal are more convenient.
