[0002] For connectors used in outdoor equipment, such as charging sockets of electric vehicles, dust covers are usually provided to prevent impurities such as dust, debris, and rainwater from entering the connector and affecting the performance of the connector.

[0003] For the charging sockets of electric vehicles, conventional dust covers mainly include two forms, namely plug-in dust covers and flip-up dust covers. The flip-up dust covers are provided with a dial block to facilitate users to open the dust cover and close and limit the dust cover when not charging. With the development of electric vehicles, various manufacturers have paid more and more attention to the appearance of charging sockets, and have defined dust covers as appearance parts to enhance the end-user experience. Usually, in order to meet the appearance requirements, the installation position of the charging socket is relatively special and the installation space is small. The dial block used in the flip-up dust cover requires a large operating space, which is difficult to meet the product space layout requirements in actual application. The plug-in dust cover is inconvenient to use and easy to lose. Summary of the invention

However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, well-known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

Unless the context clearly indicates otherwise, the singular forms of "one", "a", "said", "the" are also intended to include plural forms. In the present disclosure, "include", "comprise", "include", "have" and similar terms are used to list features, quantities, steps, operations, elements, parts, or combinations thereof, but do not exclude the presence or addition of one or more of the features, quantities, steps, operations, elements, parts, or combinations thereof.

[0032] Although the terms "first", "second", etc. may be used herein to describe a variety of different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present disclosure, a first element may be referred to as a second element, and a second element may be referred to as a first element. The term "and / or" includes multiple combinations of associated items or any one of a plurality of associated items.

[0033] According to an exemplary embodiment of the present disclosure, a dust cover is provided, which is used to cover and open an interface of an electrical connector such as a socket, so as to prevent external dust, rainwater, etc. from entering the interface when in a closed state, and to allow the interface to be docked or electrically connected with a matching connector interface when in an open state. As an example, the socket described can be a charging socket installed on an electric vehicle or other electrical equipment, such as a DC charging socket and / or an AC charging socket, but the present disclosure is not limited thereto, and the dust cover provided by the embodiments of the present disclosure can be applicable to various types of connectors that need to be covered.

[0034] The charging socket generally includes a socket interface (not shown) adapted to be electrically connected to a charging plug (not shown). Figure 1-5 In the illustrated embodiment, the charging socket further comprises a flange bracket 100, which is adapted to be fixedly mounted relative to the socket interface, for example, fixed to the body of the electric vehicle, and the flange bracket 100 is formed with an opening 101 exposing the socket interface. In order to prevent external dust, rainwater, etc. from entering the socket interface and adversely affecting the charging performance, a dust cover is provided for the charging socket.

[0035] In an exemplary embodiment, if Figure 1-7 As shown, the dust cover includes a dust cover body 210 and a push lock mechanism 220 connected to the dust cover body 210. The dust cover body 210 can be pivotally mounted to the flange bracket 100 via a first pivot 310, so that it can be switched between an open state and a closed state like a flip-top dust cover. In the closed state, the dust cover body 210 at least covers the socket interface of the charging socket. As an example, the dust cover body 210 can be on one side (e.g., Figure 2-4 and Figure 6 As shown, the flange bracket 100 has a pivot mounting structure at its side edge, and the flange bracket 100 also has a pivot mounting structure at a corresponding position. The first pivot 310 is installed to the pivot mounting structures of both the dust cover body 210 and the flange bracket 100, so that the dust cover body 210 can pivot relative to the flange bracket 100.

[0036] The push-lock mechanism 220 is used to lock or unlock the dust cover body 210 relative to the flange bracket 100, so as to allow the dust cover body 210 to pivot relative to the flange bracket 100 to be closed or opened. As shown in the figure, the push-lock mechanism 220 has a first engagement structure 221, and the first engagement structure 221 is used to engage with the flange bracket 100 when the dust cover body 210 is in a closed state, so as to hold and lock the dust cover body 210 relative to the flange bracket 100, and prevent the dust cover from being accidentally opened. At the same time, the push-lock mechanism 220 is suitable for being pressed to unlock or release the engagement of the first engagement structure 221 with the flange bracket 100, so as to allow the dust cover body 210 to pivot relative to the flange bracket 100 and be opened.

[0037] Thus, in the closed state of the dust cover, the dust cover body 210 is closed and locked relative to the flange bracket 100 to at least cover the socket interface via the engagement of the first engagement structure 221 of the push lock mechanism 220 with the flange bracket 100; and in response to the push lock mechanism 220 being pressed, the engagement of the first engagement structure 221 with the flange bracket 100 is unlocked or separated to allow the dust cover body 210 to be pivoted relative to the flange bracket 100 and opened. In this dust cover, since the push lock mechanism is mounted on the dust cover body, rather than being mounted at a spatial position near the socket interface like a paddle block for a conventional flip-type dust cover, no additional installation space is occupied, and the push lock mechanism can be operated directly in the space facing the socket interface, without requiring additional operating space, thereby well meeting the installation layout and aesthetic requirements of the charging socket.

[0038] In such Figure 1-5 In the illustrated embodiment, the flange bracket 100 includes a bracket body 110 and a flange portion 120 extending from the bracket body 110, and an opening 101 passes through the flange portion 120 and the bracket body 110 to expose the socket interface. The bracket body 110 is, for example, in a plate shape and can be fixed to a vehicle body or a device housing, and the dust cover is pivotally mounted to the flange portion 120, such as the dust cover body 210 is pivotally mounted to the top or outer end of the flange portion 120 via a first pivot 310 at its edge. Figure 1-5 As shown, the flange portion 120 is formed with a second engagement structure 121 adapted to engage with (eg, snap fit) the first engagement structure 221 of the dust cover body 210 .

[0039] In an exemplary embodiment, the flange portion 120 is formed with a notch 122 on the side surface opposite to the first pivot 310, the notch 122 being configured to at least partially receive the first engagement structure 221 of the push lock mechanism 220 in the closed state, and the second engagement structure 121 being formed as a ridge protruding at the edge of the notch 122. As an example, the first engagement structure 221 may include or be formed as a hook portion to engage or hook the ridge, thereby preventing the dust cover body 210 on which the push lock mechanism 220 is installed from being separated from the flange portion 120. It will be understood that the specific forms of the first engagement structure and the second engagement structure are not limited thereto, and those skilled in the art may adopt various structures that can engage or lock with each other.

[0040] In an exemplary embodiment, if Figure 3-6As shown, the dust cover may further include or be provided with a second pivot 410, and the push-lock mechanism 220 is rotatably connected to the dust cover body 210 via the second pivot 410. For example, the second pivot 410 is mounted to the dust cover body 210 at a position adjacent to or proximate to the side edge of the dust cover body 210 away from the first pivot 310, and the push-lock mechanism 220 is connected to the dust cover body 210 via the second pivot 410. In some examples, the second pivot 410 is rotatably mounted to the dust cover body 210, and the push-lock mechanism 220 and the second pivot 410 are fixedly connected together and rotate relative to the dust cover body 210; in other examples, the second pivot 410 may be fixedly mounted to the dust cover body 210, and the push-lock mechanism 220 may rotate relative to the second pivot 410.

[0041] Thus, when the push-lock mechanism 220 is pressed (e.g., when pressed at a position on the push-lock mechanism 220 located on the side of the second pivot 410 away from the first engagement structure 221), it will rotate relative to the dust cover body 210 in a first direction (counterclockwise in the figure), so that its first engagement structure 221 is disengaged from the flange bracket 100, allowing the dust cover body 210 to be opened. When the push-lock mechanism 220 is not pressed, the push-lock mechanism 220 can be allowed or prompted to rotate relative to the dust cover body 210 in a second direction (e.g., clockwise) opposite to the first direction, so that the first engagement structure 221 can engage with the flange bracket 100 in the closed state.

[0042] In some embodiments, Figure 1 , Figure 3-6 As shown, the dust cover body 210 may be formed with a recess 211 on the outer surface facing away from the flange bracket 100, and the push-lock mechanism 220 is partially accommodated in the recess 211, and the second pivot 410 is installed to the dust cover body 210 across the recess 211, for example, both ends of the second pivot 410 are installed to the opposite side walls of the dust cover body 210 that define the recess 211, so that in the non-pressed state, the push-lock mechanism 220 is supported by the second pivot 410 to be suspended or separated relative to the dust cover body 210, so as to facilitate the push-lock mechanism 220 to rotate relative to the dust cover body 210.

[0043] The push lock mechanism 220 may have a first end and a second end located on opposite sides of the second pivot 410, and the first end is formed with a first engagement structure 221, for example, the first engagement structure 221 is or includes a hook portion formed at the first end. Figure 1-5 and Figure 7As shown, the push lock mechanism 220 has a substantially L-shaped profile, including a first and a second part, wherein the first part is accommodated in the recess 211 of the dust cover body 210. For example, in the closed state, the exposed surface (upper surface or top surface in the figure) of the first part of the push lock mechanism 220 is substantially flush with the outer surface (upper surface or top surface in the figure) of the dust cover body 210, and the opening side of the recess 211 is retracted relative to the side surface of the flange portion 120 where the notch 122 is formed, so that the second part of the push lock mechanism is substantially flush with the side surface of the dust cover body 210, preferably also substantially flush with the side surface of the flange portion 120 where the notch 122 is formed. As a result, the push lock mechanism 220 is substantially consistent with or matches the overall appearance of the dust cover body 210 or the dust cover, and does not protrude outside the dust cover body 210, does not occupy additional space, and improves the coordination and aesthetics of the overall appearance of the dust cover.

[0044] In the first part of the push lock mechanism 220, that is, between the bent portion and the second end of the push lock mechanism 220, a through hole 224 may be formed, and the second pivot 410 is inserted through the through hole 224, so that the opposite ends of the second pivot 410 are mounted in the opposite side walls of the recess 211. Although the second pivot is an integral or single axis in the illustrated embodiment, the present disclosure is not limited thereto, for example, the second pivot may include two sub-pivots located on opposite sides of the push lock mechanism, each sub-pivot connected between the push lock mechanism and the dust cover body.

[0045] In the illustrated embodiment, Figure 3 , Figure 5 and Figure 7 As shown, the dust cover body 210 is formed with a first limiting structure 213 at the edge defining the recess 211, and the push lock mechanism 220 is formed with a second limiting structure 223 at its second end, so that in the closed state of the dust cover, the first limiting structure 213 abuts against the second limiting structure 223 to prevent the push lock mechanism 220 from further rotating in the second direction relative to the dust cover body 210. As an example, the second limiting structure 223 may include a flange formed at the second end of the push lock mechanism 220 and protruding toward the inner side wall of the recess 211.

[0046] like Figure 3 , Figure 5 and Figure 7As shown, the dust cover may also include a first elastic member 420, such as a spring, which is positioned between the recess 211 of the dust cover body 210 and the push-lock mechanism 220 (its first part) to provide an elastic force to the push-lock mechanism 220 at a position between the second end of the push-lock mechanism 220 and the second pivot 410, and the elastic force causes the push-lock mechanism 220 to rotate relative to the dust cover body 210 in the second direction, and can keep the first engaging structure 221 engaged with the flange bracket 100 in the closed state, thereby preventing the push-lock mechanism 220 from accidentally disengaging from the flange bracket 100.

[0047] In some embodiments, Figure 3 , Figure 5-7 As shown, a first positioning structure 212 is formed on the bottom surface of the recess 211, and a second positioning structure 222 is formed on the inner side of the push lock mechanism 220 facing the bottom surface of the recess 211. The first positioning structure 212 is suitable for engaging with the second positioning structure 222 to maintain the positioning of the push lock mechanism 220 relative to the dust cover body 210, for example, to prevent the push lock mechanism 220 from moving or swinging relative to the dust cover body 210 along the first pivot 410. In the illustrated embodiment, the first positioning structure 212 is a positioning column, and the second positioning structure 222 is a positioning groove, but vice versa. The first elastic member 420 can be at least partially disposed in the positioning groove, and can be sleeved on the positioning column when it is in the form of a spring.

[0048] As previously described, the push-lock mechanism 220 is supported by the second pivot 410 so that the inner side of the push-lock mechanism 220 is spaced apart from the bottom surface of the recess 211 in the closed state, and in response to pressing the push-lock mechanism 220 on the first portion of the push-lock mechanism 220, such as at a position between its second end and the second pivot 410 (as shown by the thick dashed arrow in the figure), the push-lock mechanism 220 will rotate relative to the dust cover body 210 in the first direction so that its second end moves toward the bottom surface of the recess 211, thereby squeezing or compressing the first elastic member 420, and the first engagement structure 221 formed at the first end moves outward to disengage from the flange bracket 100, thereby allowing the dust cover body 210 to be pivoted and opened. In the non-pressed state, the elastic force of the previously squeezed first elastic member 420 will cause the push-lock mechanism 220 to rotate relative to the dust cover body 210 in the second direction.

[0049] According to an embodiment of the present disclosure, a charging socket assembly is also provided, which includes a charging socket and a dust cover described in an embodiment of the present disclosure. In the illustrated embodiment, the charging socket assembly includes two charging sockets or socket interfaces spaced apart, and the flange bracket 100 has two openings that expose the two socket interfaces respectively. The charging socket assembly may include a single dust cover covering the two socket interfaces, or may include two dust covers, each dust cover being suitable for covering the corresponding socket interface. For example, the charging socket assembly may include both a DC charging socket (or socket interface) and an AC charging socket (or socket interface) to meet different charging requirements.

[0050] like Figure 2 and Figure 5 As shown, a second elastic member 320 may also be provided for the dust cover, and the second elastic member 320 is engaged with the dust cover body 210 to provide an elastic force to cause the dust cover body 210 to pivot relative to the flange bracket 100 to be opened when the dust cover body 210 is unlocked. As an example, the second elastic member 320 may include a torsion spring mounted on the first pivot 310, but the present disclosure is not limited thereto. In addition, a buffer 330 may also be provided to mitigate the impact when the dust cover body 210 is opened. Thus, when charging, the user only needs to lightly press the lock mechanism to open the dust cover, and directly press the dust cover to close it after charging is completed.

[0051] Although the embodiments of the present disclosure have been shown and described, it will be appreciated by those skilled in the art that these embodiments may be varied without departing from the principles and spirit of the present disclosure, and that the scope of protection of the present disclosure is defined by the appended claims and their equivalents. It should also be noted that, unless otherwise indicated, the terms "include", "comprise", "have" used herein do not exclude other elements or steps. In addition, any element number of a claim should not be construed as limiting the scope of protection of the present disclosure.
