Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

These terms are only used to distinguish one component from another component. For example, without departing from the scope of the present application, the first component can be referred to as the second component, and the second component can be similarly referred to as the first component.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The charging socket 1 provided by the embodiments of the present application at least includes a socket body 11 provided with a charging cavity 111, a pin electrical connection mechanism 112 and a locking mechanism 113 are arranged in the charging cavity 111, the locking mechanism 113 is located outside the pin electrical connection mechanism 112, and the buckling part 113A is arranged at one end close to the cavity opening 114 of the charging cavity 111.

[0028] In the charging socket 1, the socket body 11 provides structural support, the charging cavity 111 is used to accommodate other components, the pin electrical connection mechanism 112 establishes electrical connection with the pins of the charging plug 2 through the elastic contact points in the insertion slot 1121, and the locking mechanism 113 realizes mechanical locking based on the rotation of the buckling part 113A to prevent the plug from loosening.

[0029] When the charging plug 2 is inserted into the charging socket 1 for charging, the pin electric connection mechanism 112 abuts against the pin of the charging plug 2 to form a stable electric connection. Meanwhile, the locking mechanism 113 rotates towards the direction close to the pin electric connection mechanism 112, and when the rotating angle becomes larger and larger, the buckling part 113A is closer to the charging plug 2, and finally cooperates with the clamping groove 21 on the charging plug 2 and is buckled in the clamping groove 21 of the charging plug 2, that is, the mechanical buckling is completed.

[0030] It can be seen that through the charging socket of the embodiment of the present application, the charging plug can be effectively prevented from being accidentally or maliciously pulled out during charging, thereby avoiding charging interruption and the like, which not only significantly improves the stability and safety of the charging process, but also improves the user experience.

[0031] In an optional embodiment of the present embodiment, the charging inner cavity 111 is provided with a rotating mechanism 114 for driving the locking mechanism 113 to rotate, and the rotating mechanism 114 is connected with the other end of the locking mechanism 113. When the charging plug 2 is inserted into the charging socket 1 for charging, the rotating mechanism 114 is used to drive the locking mechanism 113 to rotate towards the direction close to the pin electric connection mechanism 112, so that the buckling part 113A is buckled in the clamping groove of the charging plug 2 and is in a locked state; when the charging of the charging plug 2 is completed, the rotating mechanism 114 is used to drive the locking mechanism 113 to rotate away from the pin electric connection mechanism 112, so that the buckling part 113A is separated from the clamping groove and is in an open state.

[0032] Specifically, when the charging plug is inserted into the charging inner cavity 111 of the charging socket 1 for charging, the rotating mechanism 114 is triggered to drive the locking mechanism 113 to rotate towards the direction close to the pin electric connection mechanism 112. With the rotation, the buckling part 113A of the locking mechanism 113 is tightly matched with the clamping groove of the charging plug and buckled, and enters a locked state (at this time, based on the completion of the preset angle rotation of the rotating mechanism 114, the corresponding buckling part 113A is in a locked state and will not continue to rotate), which ensures the stable connection of the charging plug 2 during charging. After charging is completed, the rotating mechanism 114 is triggered again to drive the locking mechanism 113 to rotate away from the pin electric connection mechanism 112, so that the buckling part 113A is separated from the clamping groove of the charging plug, and the buckling part 113A is in an open state (unlocked), and the charging plug can be safely pulled out. Through the setting of the rotating mechanism 114 as a control core, the locking mechanism 113 is accurately driven to complete the corresponding rotating action by detecting the insertion and charging completion signal of the charging plug 2, and the whole locking and unlocking process is realized.

[0033] In an optional embodiment of the present embodiment, the locking mechanism 113 comprises a first locking assembly 1131 and a second locking assembly 1132 located on the left and right sides of the pin electrical connection mechanism 112, and the clamping portion 113A comprises a first clamping portion 1132A and a second clamping portion 1131A. One end of the first locking assembly 1131 is connected with the first rotating shaft 1141 in the rotating mechanism 114, one end of the second locking assembly 1132 is connected with the second rotating shaft 1142 in the rotating mechanism 114, the other end of the first locking assembly 1131 is provided with the first clamping portion 1132A for approaching the cavity opening 114 of the charging inner cavity 111, and the other end of the second locking assembly 1132 is provided with the second clamping portion 1131A for approaching the cavity opening 114 of the charging inner cavity 111.

[0034] Specifically, when the charging plug 2 is inserted into the charging socket 1, the first locking assembly 1131 rotates towards the side close to the pin electrical connection mechanism 112, the second locking assembly 1132 rotates towards the other side close to the pin electrical connection mechanism 112, and the first clamping portion 1132A and the second clamping portion 1131A approach the cavity opening 114 and are clamped in the first clamping groove 211 and the second clamping groove 212 respectively arranged on the two sides of the clamping groove 21. Thus, the double-sided locking mechanism can better adapt to charging plugs of different sizes or specifications, reasonably adjust the position of the clamping portion and the rotation angle of the locking assembly, significantly improve the compatibility, and lay a foundation for the multi-scene application of the charging socket.

[0035] In an optional embodiment of the present embodiment, the first clamping portion comprises a first protruding portion protruding from the other end of the first locking assembly towards the cavity opening, and the included angle between the first protruding portion and the inner side of the first locking assembly is 20-60 degrees. The second clamping portion comprises a second protruding portion protruding from the other end of the second locking assembly towards the cavity opening, and the acute angle between the second protruding portion and the inner side of the second locking assembly is 20-60 degrees. Through the reasonable included angle design between the protruding portion and the inner side of the locking assembly, not only the mechanical cooperation between the charging plug and the locking mechanism is optimized, but also the durability of the locking mechanism during use is enhanced. The moderate included angle range can significantly reduce the friction when the plug is inserted and pulled out, prolonging the service life of the clamping portion and the plug clamping groove.

[0036] In an optional embodiment of the present embodiment, when the first clamping portion 1132A and the second clamping portion 1131A are in the locked state, the first locking assembly 1131 is parallel to the second locking assembly 11332; when the first clamping portion 1132A and the second clamping portion 1131A are in the open state, the acute angle between the first locking assembly 1131 and the second locking assembly 1132 is 30-45 degrees.

[0037] Specifically, during operation, when the charging plug 2 is inserted into the charging socket 1, the rotating mechanism 114 drives the first locking assembly 1131 and the second locking assembly 1132 to rotate gradually from an opening angle of 30 to 45 degrees to a parallel state, realizing the transition from the open state to the locked state. After charging is completed, the rotating mechanism reverses its action, rotating the first locking assembly 1131 and the second locking assembly 1132 from the parallel state to an opening angle of 30 to 45 degrees, completing unlocking and being in the open state. By explicitly designing the angles of the first locking assembly 1131 and the second locking assembly 1132 in the locked state and the open state, the action logic of the locking mechanism is optimized. In the locked state, the parallel assembly position provides the maximum fixing force for the plug; while in the open state, the acute angle of 30 to 45 degrees provides sufficient space for the insertion and removal of the charging plug, while maintaining the action efficiency and mechanical reliability of the assembly. In addition, the switching between the parallel state and the opening state is precisely controlled by the rotating mechanism, making the action of the locking assembly synchronous and consistent, thereby avoiding the locking failure caused by incomplete unilateral action.

[0038] In an optional embodiment of the present embodiment, first and second protection structures 115 and 116 are respectively arranged on the left and right sides of the socket body 11 near the cavity opening 114. When the first and second buckle portions 1132A and 1131A are in the open state, the first protrusion is located in the charging cavity corresponding to the inner side of the first protection structure, and the second protrusion is located in the charging cavity corresponding to the inner side of the second protection structure.

[0039] Specifically, through the arrangement of the protection structure, important protection is provided for the locking mechanism 113. When the locking mechanism 113 is in the open state, the first and second protrusions are respectively located in the charging cavity regions corresponding to the inner sides of the first and second protection structures 115 and 116. This layout can effectively prevent external objects (such as dust, debris or other foreign matter) from entering the active area of the locking mechanism, and improve the shielding function of the locking mechanism, achieving effective protection of the locking assembly.

[0040] In an optional embodiment of the present embodiment, the charging socket further comprises a sensing mechanism for sending a sensing signal to the rotating mechanism to rotate accordingly when the plug electrically connecting mechanism and the plug of the charging plug abut. Through the linkage design of the sensing mechanism, the plug electrically connecting mechanism and the rotating mechanism, the accuracy and timing consistency of the action are ensured, and the real-time transmission of the sensing signal makes the action of the locking mechanism 113 closely cooperate with the insertion state of the plug, avoiding the locking or unlocking failure caused by different timing.

[0041] In an optional embodiment of the present embodiment, the charging socket further comprises a control mechanism that sends a corresponding control signal to the rotating mechanism to rotate accordingly when the control mechanism receives a locking request or an opening request. By providing a control mechanism in the charging socket 1, the action of the rotating mechanism is directly controlled by external instructions or user input, meeting the diversified needs in different scenarios.

[0042] It should be noted that the charging socket provided by the present embodiment is suitable for two-phase or three-phase charging plugs with a card slot (as shown in Figure 6 and Figure 7 The card slot can not only be buckled with the charging socket, but also serve as a convenient contact hand-held part to facilitate the charger to hold and insert the charging plug into the charging socket.

[0043] The present embodiment also provides a charging pile comprising a charging pile body and a charging socket as described in the above embodiments, and the charging socket is installed in the charging pile body.

[0044] The charging socket and the charging pile of the present utility model, by setting locking mechanism in the socket, when the charging plug is inserted into the charging socket for charging, the locking mechanism rotates towards the direction close to the pin electric connection mechanism, so that the buckling part is buckled in the card slot of the charging plug, thereby effectively preventing the plug from being accidentally or maliciously pulled out, avoiding the interruption of charging, not only significantly improving the stability and safety of the charging process, but also improving the user experience.

For those skilled in the art, any equivalent modification or replacement of the utility model is also within the scope of the utility model, therefore, any equivalent transformation, modification, improvement, etc. made without departing from the spirit and principle range of the utility model should be covered within the scope of the utility model.
