[0031] like Figures 1 to 7 As shown, this utility model provides an electric vehicle charging and discharging connector 100 for plugging into a socket 200, including a housing 110, a button 120 and a locking member 130.
[0032] The button 120 is disposed on the housing 110 and can slide between a locked position and an unlocked position relative to the housing 110 along a first direction. The button 120 is provided with a first latching part 126, which is configured to engage with a second latching part 210 on the socket 200. When the connector 100 and the socket 200 are plugged in and the button 120 is in the locked position, the first latching part 126 and the second latching part 210 are engaged with each other. When the button 120 is in the unlocked position, the first latching part 126 and the second latching part 210 are separated from each other. The locking member 130 is disposed on the housing 110 and can slide back and forth between an initial position and a locked position relative to the housing 110. When the locking member 130 is in the locked position, the locking member 130 restricts the sliding of the button 120 along the first direction. When the locking member is in the initial position, the button 120 can slide along the first direction.
[0033] Understandably, during charging, the connector 100 and socket 200 of this invention need to be plugged into each other. During this plugging process, the button 120 must first be pressed to move it from the locked position to the unlocked position. Then, the connector 100 is inserted into the socket 200. Finally, the button 120 is moved back to the locked position so that the first latching part 126 on the button 120 can engage with the second latching part 210 on the socket 200. After completing the plugging action between the connector 100 and the socket 200, the locking member 130 can be pushed to restrict the sliding of the button 120 along the first direction, thereby keeping the button 120 in the locked position and ensuring that the connector 100 will not easily detach from the socket 200 under external force. Accordingly, after charging, the locking member 130 can be moved back to its initial position. At this time, the button 120, no longer blocked by the locking member 130, can move freely in the first direction. Therefore, when the button 120 is moved to the unlocked position again, the first locking part 126 and the second locking part 210 can be separated, thereby separating the connector 100 from the socket 200. The electric vehicle charging and discharging connector 100 of this utility model improves charging safety and reliability by setting a two-stage locking structure. At the same time, the user can unlock it simply by moving the button 120 and the locking member 130, ensuring user convenience.
[0034] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments of this utility model, the housing 110 has a sliding groove 111 along a first direction and an insertion hole 112 along a second direction. The insertion hole 112 communicates with the sliding groove 111, allowing the connector 100 and the socket 200 to be plugged into each other along the second direction. The button 120 slides and engages with the sliding groove 111 along the first direction. The first engaging part 126 is located within the sliding groove 111. During the insertion of the connector 100 and the socket 200, the second engaging part 210 can extend into the sliding groove 111 through the insertion hole 112 and engage with the first engaging part 126. The sliding groove 111 provides a limiting and sliding guide for the button 120, ensuring the accuracy and reliability of the engagement process, avoiding poor contact caused by incomplete insertion, and improving charging efficiency and stability.
[0035] like Figure 2 As shown, in some embodiments of this utility model, the first direction and the second direction are perpendicular to each other. The first direction can be vertical, and the second direction can be horizontal. In use, the connector 100 can be horizontally pushed to connect to the socket 200, and the button 120 can be vertically pressed to lock and unlock. This design is highly compatible with user habits, simplifying the structure while ensuring user convenience.
[0036] Furthermore, such as Figure 2 As shown, in some embodiments of this utility model, the sliding direction of the locking member 130 can be a third direction, and the first direction, the second direction and the third direction can be perpendicular to each other, that is, the first direction, the second direction and the third direction form mutually perpendicular coordinate axes.
[0037] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the button 120 is U-shaped and includes a body 121 and two extension walls 122 located at both ends of the body 121. The housing 110 has two sliding grooves 111, and the two extension walls 122 slide in cooperation with the two sliding grooves 111 respectively. Two first engaging portions 126 are provided, each located on one of the two extension walls 122. The extension walls 122 have clearance grooves 123, and the first engaging portions 126 are elastic latches formed at the clearance grooves 123. The U-shaped button 120 can be inserted into the housing 110 with its opening facing downwards. The cooperation between the two extension walls 122 and the two sliding grooves 111 increases the stability of the button 120 during sliding. Furthermore, both the first engaging portions 126 and the second engaging portions 210 can be made of an elastic material, such as plastic.
[0038] like Figure 2 and Figure 6 As shown, in some embodiments of this utility model, the housing 110 has a receiving groove 113, and the body 121 is embedded in the receiving groove 113. When the button 120 is in the locked position, the outer surface of the body 121 is flush with the outer surface of the housing 110. Figure 2 In the middle, button 120 is in the locked position and is basically flush with the outer surface of housing 110. When button 120 is pressed, receiving groove 113 can provide guidance for button 120.
[0039] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the button 120 is provided with a blind groove 124 and a through groove 125. The blind groove 124 does not penetrate the button 120 in the first direction, but is connected to the through groove 125 in the third direction. The through groove 125 penetrates the button 120 in the first direction. The locking member 130 is provided with a stop block 131. When the locking member 130 is in the locked position, the stop block 131 is located in the blind groove 124. At this time, the stop block 131 will restrict the movement of the button 120, thereby achieving the purpose of secondary locking. When the locking member 130 is in the initial position, the stop block 131 is located in the through groove 125. At this time, the button 120 can slide freely in the first direction.
[0040] like Figure 6 and Figure 5As shown, in some embodiments of this utility model, the sliding direction of the locking member 130 is the third direction. The housing 110 has a limiting groove 114 along the third direction. The locking member 130 is configured to slide along the limiting groove 114. The limiting groove 114 can provide limiting and guiding for the locking member 130. The button 120 is also provided with a hook 132. When the locking member 130 is in the initial position and the locked position, the hook 132 is located in the through groove 125. The button 120 is engaged in the limiting groove 114 by the hook 132, so that the sliding of the button 120 will not disengage from the limiting groove 114.
[0041] like Figure 6 As shown, in some embodiments of this utility model, a reset spring 140 is provided between the button 120 and the housing 110. The reset spring 140 is configured to make the button 120 always tend to move toward the locked position, so that after the user presses the button 120, the button 120 can return to the locked position under the action of the reset spring 140.
[0042] like Figure 6 As shown, in some embodiments of this utility model, two reset springs 140 are provided, which makes the sliding and reset of the button 120 more stable and smooth.
[0043] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
