[0059] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application.

[0060] To enable electric vehicles to be charged via DC fast charging at dedicated charging stations and via AC slow charging at home when no dedicated charging station is available, electric vehicle charging interfaces typically have two charging ports side-by-side: a DC charging port and an AC charging port, or a DC socket and an AC socket. Current vehicles have very limited design space for the charging interface, and existing charging interfaces are generally too large, thus compressing the design space of other components. To address this, this application proposes a compact electric vehicle charging interface. The electric vehicle charging interface includes a base and a charging cover kit.

[0061] Figure 1 An example of the base 3 for an electric vehicle charging interface of this application is shown schematically in a perspective view.

[0062] The substrate 3 includes:

[0063] A first charging port 301 and a second charging port 302 are arranged side by side. The first charging port 301 is, for example, an AC charging port, and the second charging port 302 is, for example, a DC charging port.

[0064] A first pivoting structure 311 is used to install a first cover 1 for covering the first charging port 301 and to allow the first cover 1 to pivot relative to the base 3 to open and close.

[0065] The first slot 321 is used to keep the first cover 1 in a closed state by engaging with the first hook 111 of the first cover 1;

[0066] A second pivoting structure 312 is used to mount a second cover 2 for covering the second charging port 302 and to allow the second cover 2 to pivot relative to the base 3 for opening and closing; and

[0067] The second slot 322 is used to keep the second cover 2 in a closed state by engaging with the second hook of the second cover 2;

[0068] The first pivot structure 311 is disposed on the first pivot side of the first charging port 301 facing the second charging port 302, the first slot 321 is disposed on the other side of the first charging port 301 opposite to the first pivot side, the second pivot structure 312 is disposed on the second pivot side of the second charging port 302 facing the first charging port 301, and the second slot 322 is disposed on the other side of the second charging port 302 opposite to the second pivot side.

[0069] That is, the first pivot structure 311 and the second pivot structure 312 are disposed between the first charging port 301 and the second charging port 302, while the first card slot 321 and the second card slot 322 are disposed on the far side of the first charging port 301 and the second charging port 302 away from each other.

[0070] This allows for a more compact structure of the base 3 and makes the opening and closing of the first cover 1 and the second cover 2 easier. "Side by side" can mean side by side or side by side.

[0071] Figure 2 A stereoscopic diagram schematically illustrates the concept from another perspective. Figure 1 The base 3.

[0072] According to an exemplary embodiment, such as Figure 1 and Figure 2 As shown, the base 3 includes a first boss protruding from the base surface 30 of the base 3. The first boss includes a first annular body surrounding the first charging port 301 and a first flange structure 341 connected to the first annular body. The gap between the first flange structure 341 and the base surface 30 forms the first slot 321.

[0073] This design has the following advantages over the prior art: In the prior art, slots are usually formed by directly cutting grooves on the annular body, which usually results in a thicker annular body. However, the first flange structure 341 of this application eliminates the need to cut grooves on the first annular body, so the first annular body can be designed with a thinner wall thickness. Some existing substrates already have annular bodies, so the first flange structure 341 or the first slot 321 can be easily formed by simple modifications to the existing substrate.

[0074] According to an exemplary embodiment, such as Figure 1 As shown, the first annular body is composed of a first arc segment 3311 and a first straight segment 3312. The first flange structure 341 is advantageously configured so as not to increase the maximum length and maximum width of the first boss, see [reference needed]. Figure 1 The length and width directions of the structure. Specifically, the first flange structure 341 is disposed within the rectangle defined by the maximum length and maximum width of the first annular body. Figure 1 In this configuration, the first flange structure 341 is exemplarily disposed at the connection position between the first arc segment 3311 and the first straight segment 3312.

[0075] According to an exemplary embodiment, such as Figure 1 As shown, the first flange structure 341 forms the right-angle portion of the first boss. The first hook 111 of the first cover 1 (see...) Figure 10 It is usually straight, and the right angle of the first boss can be easily matched with the shape of the first hook 111.

[0076] According to an exemplary embodiment, such as Figure 2As shown, the first boss includes a first support wall 361 that stands on the base surface 30 and supports the first flange structure 341. The first support wall 361 may be flush with the first straight segment 3312. The first support wall 361 prevents the first flange structure 341 from being suspended, thereby improving strength. However, it is also possible to have the first support wall 361 absent.

[0077] According to an exemplary embodiment, such as Figure 1 As shown, the base 3 includes a first groove 351 adjacent to the first charging port 301. The first groove 351 is used to accommodate the mechanical locking mechanism 40 of the corresponding charging gun 4 (AC charging gun). The first groove 351 may be arranged adjacent to the first straight segment 3312. The first groove 351 is, for example, trapezoidal. Figure 3 An example of a charging gun 4 is shown schematically in a perspective view. A trapezoidal protrusion corresponding to the first groove 351 can be seen on the mechanical locking mechanism 40 of the charging gun 4. For example, a locking hook is provided on the trapezoidal protrusion for engaging with a locking groove on the base 3.

[0078] The second charging port 302 and its related elements can be similar to the first charging port 301 and its corresponding elements. That is, the base 3 may include a second boss protruding from the base surface 30 of the base 3. The second boss includes a second annular body surrounding the second charging port 302 and a second flange structure 342 connected to the second annular body. The gap between the second flange structure 342 and the base surface 30 forms the second slot 322. The second flange structure 342 forms the right-angle portion of the second boss. The second annular body is composed of a second arc segment 3321 and a second straight segment 3322. The second boss includes a second support wall standing on the base surface 30 and supporting the second flange structure 342. The base 3 includes a second groove 352 adjacent to the second charging port 302. The second groove 352 is used to accommodate the mechanical locking mechanism 40 of the corresponding charging gun 4 (DC charging gun). The second groove 352 is disposed adjacent to the second straight segment 3322.

[0079] According to an exemplary embodiment, such as Figure 1 As shown, the first pivot axis of the first pivot structure 311 is coaxial with the second pivot axis of the second pivot structure 312. This allows the structure of the base 3 to be compact.

[0080] Figure 4 An example of an electric vehicle charging interface according to this application is schematically shown in a perspective view, wherein the two covers of the charging cover kit of the electric vehicle charging interface are in a closed state. The charging cover kit includes:

[0081] A first cover 1 for the first charging port 301, the first cover 1 having a first cover pivot portion 101 for engaging with a first pivot structure 311 of the base 3 and a first hook 111 for engaging with a first slot 321 of the base 3 (see...). Figure 10 );as well as

[0082] A second cover 2 for the second charging port 302, the second cover 2 having a second cover pivot portion 202 for engaging with a second pivot structure 312 of the base 3 and a second hook for engaging with a second slot 322 of the base 3.

[0083] According to an exemplary embodiment, the charging cover kit includes a first limiting portion for limiting the pivot opening angle of the first cover 1 and a second limiting portion for limiting the pivot opening angle of the second cover 2. The first limiting portion, for example, allows the first cover 1 to open only to a first upright position, and the second limiting portion, for example, allows the second cover 2 to open only to a second upright position. This facilitates the opening and closing of the first cover 1 and the second cover 2. The first and second upright positions, for example, correspond to a pivot position of 90° or a position with a pivot angle slightly larger than 90°, so as to facilitate the insertion of the charging gun 4. "Slightly larger" refers, for example, to an angle value between 0° and 20° larger.

[0084] Figure 5 A stereoscopic diagram schematically illustrates the concept from another perspective. Figure 4 The electric vehicle charging interface, wherein the first cover 1 of the charging cover kit is in the open state.

[0085] According to an exemplary embodiment, the first cover 1 has a first inclined surface 121 adapted to abut against the second cover 2 when opened to a second upright position as the second limiting portion, and the second cover 2 has a second inclined surface 222 adapted to abut against the first cover 1 when opened to a first upright position as the first limiting portion. (See also...) Figure 5 The first inclined surface 121 in particular abuts against the second inclined surface 222 of the second cover 2, and the second inclined surface 222 in particular abuts against the first inclined surface 121 of the first cover 1. Figure 5 The gap between the first inclined plane 121 and the second inclined plane 222 is only drawn for ease of labeling.

[0086] Figures 6 to 8 The illustration shows another possibility for the first limiting part. Figure 6 The schematic diagram shows the first cover pivot 101 and the base surface 30 of the base 3 before the improvement. The first cover pivot 101 can rotate 180° relative to the base 3, for example, without other interference. Figure 7The improved first cover pivot 101 is schematically shown. According to an exemplary embodiment, the first cover pivot 101 has a first stop surface 131 that stops on the base 3 when the first cover 1 is opened to a first upright position as the first limiting portion. Figure 8 Schematic illustration Figure 7 After the first cover pivot 101 rotates 90°, it stops on the base 3 with the first stop surface 131. The first stop surface 131 can be changed accordingly depending on the angle corresponding to the first upright state.

[0087] According to an exemplary embodiment, the second cover pivot portion 202 has a second stop surface that stops on the base 3 when the second cover 2 is opened to the second upright position as the second limiting portion.

[0088] According to an exemplary embodiment, such as Figure 1 and Figure 4 As shown, the first cover 1 is configured to cover the first charging port 301 and the first groove 351 of the base 3.

[0089] According to an exemplary embodiment, such as Figure 1 and Figure 4 As shown, the second cover 2 is configured to cover the second charging port 302 and the second groove 352 of the base 3.

[0090] However, if the first groove 351 and the second groove 352 are not provided on the base 3, the first cover 1 and the second cover 2 may also be changed accordingly.

[0091] According to an exemplary embodiment, such as Figure 4 , Figure 9 and Figure 10 As shown, the first cover 1 includes a first cover body 11 and a first lever element 141 pivotally mounted on the first cover body 11. The first lever element 141 is generally L-shaped (viewed along the direction of the pivot axis of the first lever element 141). A first latch 111 is provided at the free end of one side of the L-shape, and the other side of the L-shape forms a first operating portion 151 for operating the first latch 111. The pivot axis of the first lever element 141 is located at the inflection point of the L-shape. Figure 9 An example of the first lever element 141 is shown schematically in a three-dimensional view. Figure 10 A stereoscopic diagram schematically illustrates the concept from another perspective. Figure 9 The first lever element 141.

[0092] According to an exemplary embodiment, such as Figure 9 and Figure 10As shown, the width of the first operating part 151 is greater than the width of the first hook 111. This allows for convenient operation without affecting the functionality of the first hook 111.

[0093] According to an exemplary embodiment, the first cover 1 includes a first locking spring for causing the first hook 111 to move toward a locking position. This ensures that the first hook 111 is locked into the first slot 321 in the locking position, thereby ensuring that the first cover 1 is stably held in a closed state. The first locking spring, for example, is acted upon by the first cover body 11 to push the first operating part 151 of the first lever element 141 upward, thereby causing the first hook 111 to move toward the locking position, and when the driver presses the first operating part 151 downward, the first hook 111 disengages from the locking position.

[0094] According to an exemplary embodiment, the second cover 2 includes a second cover body 22 and a second lever element pivotally disposed on the second cover body 22. The second lever element is generally L-shaped, and a second hook is disposed at the free end of one side of the L-shape. The other side of the L-shape forms a second operating portion 252 for operating the second hook.

[0095] According to an exemplary embodiment, the width of the second operating part 252 is greater than the width of the second hook.

[0096] According to an exemplary embodiment, the second cover 2 includes a second locking spring for causing the second hook to move toward a locking position.

[0097] According to an exemplary embodiment, the electric vehicle charging interface includes a first spring for loading the first cover 1 of the charging cover assembly toward the open position and a second spring for loading the second cover 2 of the charging cover assembly toward the open position. The first and second springs allow the first cover 1 and the second cover 2 to automatically spring open after the latch is released, eliminating the need for dedicated grips and allowing the first cover body 11 and the second cover body 22 to be designed to be flat.

[0098] According to an exemplary embodiment, the first spring is disposed between the first cover 1 and the base 3 on the first pivot side, and the second spring is disposed between the second cover 2 and the base 3 on the second pivot side. The first and second springs are, in particular, torsion springs. This simplifies the design.

[0099] It should be noted that although the elements associated with the first charging port and the second charging port are similar to each other and both have the mentioned exemplary features in the accompanying drawings and the above description, it is also possible to conceive differently: the mentioned features are implemented only on the elements associated with one of the charging ports, while the corresponding elements associated with the other charging port are implemented in other ways and do not conform to the mentioned exemplary features.

[0100] In this document, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features defined as "first" or "second" may explicitly or implicitly indicate the inclusion of at least one of those features. The description of the design and advantages of elements related to the first charging port can be similarly applied to corresponding elements related to the second charging port. For brevity, some "second" features are not given reference numerals, but their location and configuration can obviously be understood in analogous to the corresponding "first" features.

[0101] Although specific embodiments of this application are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of this application. Various substitutions, modifications, and alterations can be conceived without departing from the spirit and scope of this application.
