Description

Technical Field

[0001] The utility model belongs to the technical field of sockets, and particularly relates to a switch linkage locking structure of a discharge socket. Background Art

[0002] The existing power strip structure is mostly a one-piece structure design of a cable and a power strip. In some scenarios, such as the socket for discharging when a new energy vehicle is connected to the vehicle end, since the cable itself can be used for both charging and discharging, in order to improve its utilization rate, it is set as a detachable structure, that is, the cable itself is a cable that can be connected to the vehicle port and the external power three-pin socket. At the same time, using this cable, a split power strip structure is set up. There is a special docking socket on this discharge power strip for connecting the cable plug, and then the cable is connected to the vehicle to power on the discharge power strip.

[0003] Since this socket is a split cable, in order to ensure the connection stability at both ends of this detachable structure, a locking structure needs to be set up. There is such a locking structure in the prior art, and the operating end of the locking structure is set on the plug or the socket, but an additional pressing structure needs to be set up to achieve the operation. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides a switch linkage lock of a discharge power strip, aiming to form a one-point control in linkage with the power-on key necessary for the existing power strip, and avoid the inconvenience brought by separate control in the prior art.

[0005] The technical solution adopted by the utility model is as follows:

[0006] In the first aspect, the utility model provides a switch linkage locking structure of a discharge socket, which is arranged in the docking socket of the discharge socket and is used for realizing detachable connection of an externally inserted plug to the docking socket, including a trigger mechanism and a lock that are movably connected to the discharge socket, and the plug is clamped and limited through the lock; the trigger mechanism is linked with the lock, and at the same time, the trigger mechanism is linked with the power-on key arranged on the discharge socket for controlling the power-on state of the discharge socket.

[0007] It should be noted that the discharge socket is not limited to the power strip structure for discharging used in new energy vehicles. As long as there is any structure that realizes discharge by connecting a plug cable to a socket, the locking structure in this solution can be used for locking between the plug and the socket. Similarly, in order to improve the connection stability, the locking structure can also be set on the jack positions of ordinary sockets, that is, a corresponding docking socket is provided on each socket, and an ordinary plug can be inserted. After a special clamping plug is inserted, it is connected by the locking structure to maintain the locked state.

[0008] The lock, trigger mechanism and switch key are all in linkage relationship, that is, the discharge socket or ordinary socket has a switch key for controlling the discharge socket or the internal conduction / power off of the socket, and the linkage relationship between the lock and the trigger mechanism is to change the state by the two-stage adjustment of the switch key. That is, there are at least two states, one is that when the switch key is closed and locked, the trigger mechanism links the lock to lock and fix the plug inserted into the docking socket, and the other is that when the switch key is opened, the trigger mechanism links the lock to release the plug. In the above two states, the switch key turns on the power in the socket, and the inserted plug is locked and fixed by adjusting the lock by the trigger mechanism, so as to maintain the fixed connection state between the plug and the socket in the power-on state, and improve the stability; the switch key disconnects the power supply in the socket, and the trigger mechanism adjusts the lock to release the plug, and the plug can be taken out or inserted at this time. The above content is intended to illustrate its principle and relative linkage relationship. The two-stage switch key is a common structural feature of the existing switch key. The present application is not limited to the cooperation of the two-stage switch key, but it is only a basic way to link with at least two states and to maintain the switch key state without external force.

[0009] In combination with the first aspect, the utility model provides a first implementation manner of the first aspect, wherein the switch key and the trigger mechanism are an integrated connection structure.

[0010] In combination with the first aspect or the first implementation of the first aspect, the utility model provides a second implementation of the first aspect, wherein the trigger mechanism is transmission-connected with the lock, and the trigger mechanism drives the lock to engage and limit the plug.

[0011] In combination with the first aspect or the first embodiment of the first aspect, the utility model provides a third embodiment of the first aspect, wherein the discharge socket has a structure for guiding the elastic deformation of the lock, and the elastic deformation of the lock provides an elastic limiting force to the plug.

[0012] In combination with the first aspect or the first embodiment of the first aspect, the utility model provides a fourth embodiment of the first aspect, wherein the discharge socket is provided with an elastic member that provides the lock with a force that always allows the plug to move in a release direction, and the trigger mechanism blocks the lock from moving in the release direction when the switch key is in a power-on state.

[0013] In combination with the fourth implementation of the first aspect, the utility model provides a fifth implementation of the first aspect, wherein the lock buckles are a group of rotating structures symmetrically arranged in the discharge socket, and the elastic member is a tension spring arranged between the lock buckles and providing an inward clamping force to the lock buckles on the corresponding side respectively.

[0014] Combined with the fifth embodiment of the first aspect, the present utility model provides a sixth embodiment of the first aspect. The triggering mechanism is a T-shaped member disposed on the power switch and extending to both sides to form corresponding locking structures on both sides. The T-shaped member has an abutting end that abuts and blocks the rotation of the lock, and the abutting end is an inclined surface inclined in the direction of movement of the triggering mechanism.

[0015] Combined with the fifth embodiment of the first aspect, the present utility model provides a seventh embodiment of the first aspect. A rotating shaft is provided in the discharge socket, and the lock is a strip structure and is rotatably connected to the discharge socket through the rotating shaft.

[0016] Combined with the first aspect or the first embodiment of the first aspect, the present utility model provides an eighth embodiment of the first aspect. The power switch has two strokes, and a compression spring that always acts outward on the power switch is provided in the discharge socket.

[0018] The beneficial effects of the present utility model are as follows:

[0019] The locking structure designed by the present utility model is linked with the power switch, which can avoid separately providing a button for controlling the lock and directly integrating it on the power switch that is provided in the existing discharge socket. Thus, it cooperates with the operation mechanism of the switch to control power connection, maintains a stable connection between the plug and the socket during power-on, avoids potential safety hazards caused by disconnection between the socket and the cable during the discharge process, and enables the plug to be freely inserted and removed during power-off.

[0038] Embodiment:

[0039] This embodiment discloses a switch linkage lock 5 for a discharge socket, which can be used on any socket structure to connect an external plug 1 structure, so that the external plug 1 and the socket can maintain a detachable connection state that can be opened and closed, improving the connection stability and avoiding potential safety hazards caused by disconnection during connection.

[0040] In this embodiment, it mainly aims at the application of a split cable and a discharge socket 2 in the field of new energy vehicles. This split cable has two plugs 1. One is a universal connector for connecting to a vehicle, and the other is a plug 1 that can connect to a common socket to achieve a charging function and can also connect to a split discharge socket 2 to achieve discharge. The plug 1 is not limited to a specific shape and specification, but for the purpose of explaining its connection relationship and functional relationship, the plug 1 in this embodiment is a three-pin specification, that is, it meets the charging and discharging requirements of 10A and 16A.

[0041] Specifically, the switch-linked lock 5 structure includes a lock 5 and a trigger mechanism 8 provided in the discharge socket 2. The discharge socket 2 has a docking socket 3 for connecting the plug 1. When the plug 1 is inserted into the docking socket 3, it is snap-connected. Then, the trigger mechanism 8 links the lock 5 to lock the plug 1 and the socket at the docking socket 3. If the plug 1 needs to be separated from the discharge socket 2, the lock 5 is opened by the trigger mechanism 8 to pull out the plug 1.

[0042] Among them, the trigger mechanism 8 is linked with the power switch 4 provided on the discharge socket 2 for controlling the conduction of the internal circuit of the discharge socket 2. That is, at least two states are adjusted by triggering the power switch 4, namely, the discharge socket 2 is powered on and powered off. When switching between the two states, the trigger mechanism 8 will also act simultaneously to link the lock 5 to realize the conversion between the two states of locking and releasing, thus connecting the original trigger mechanisms for separately controlling the lock 5 and the power-on of the discharge socket 2 to form a single trigger mechanism.

[0043] It should also be noted that a feedback signal circuit is provided in the discharge socket 2 to feedback the connection state between the discharge socket 2 and the external plug 1. Since the lock 5 structure linked by the switch is used to connect the discharge socket 2 and the plug 1 in this embodiment, the connection relationship between the discharge socket 2 and the plug 1 is judged by relying on the lock 5 structure for triggering. Specifically, the trigger mechanism 8 and / or the lock 5 match through the feedback signal circuit in the discharge socket 2 to feedback a state change signal to the vehicle end connected to the discharge socket 2. That is to say, there is also a component in the discharge socket 2, which can be the power switch 4 connected in series in the feedback signal circuit. By triggering the state change by the action of one or both of the trigger mechanism 8 or the lock 5, the feedback signal circuit is used to feedback information to judge the connection relationship between the discharge socket 2 and the plug 1 at this time, and further judge whether the vehicle end discharges to the discharge socket 2 at this time.

[0044] Based on this, several implementation manners are disclosed in this embodiment.

[0045] For the triggering method of the power switch 4, there are various linkage methods.

[0046] As an implementation manner, when the power switch 4 itself is a mechanical button, the internal trigger mechanism 8 will directly establish a transmission connection relationship with the power switch 4 itself. After an external force acts on the power switch 4 to cause a relative displacement between it and the discharge socket 2, the trigger mechanism 8 will also act accordingly and then link the lock 5.

[0047] As an implementation manner, the on-off key 4 control mechanism is based on the circuit control mechanism provided in the discharge socket 2, that is, the weak current controls the on-off of the strong current circuit. Then, the triggering mechanism 8 can be linked with the on-off key 4 in a signal transmission linkage manner. That is, the triggering mechanism 8 itself is an electric module controlled by the control circuit where the on-off key 4 is located. When the on-off key 4 is triggered by external pressing or touching, etc., the control circuit will not only control the relay action on the strong current circuit, but also simultaneously link the triggering mechanism 8 to drive the locking latch 5 to act.

[0048] In the solution of adopting a mechanical trigger on-off key 4, the following implementation manners exist for the linkage relationship among the on-off key 4, the triggering mechanism 8, and the locking latch 5.

[0049] As an implementation manner, the on-off key 4 and the triggering mechanism 8 are designed as an integral structure, while the locking latch 5 is an independent moving part. That is, the triggering mechanism 8 has an end exposed on the surface of the discharge socket 2, which is convenient for pressing and pushing the triggering mechanism 8 to act from the outside. And the triggering mechanism 8 also has an end that cooperates with the locking latch 5 for transmission, driving the locking latch 5 to act and change its state through the overall displacement of the triggering mechanism 8.

[0050] As an implementation manner, the on-off key 4, the triggering mechanism 8, and the locking latch 5 are independent of each other. The on-off key 4 itself can adopt existing control logics and structures. Only a triggering mechanism 8 for independent action transmission control is separately provided in the discharge socket 2. Since the on-off key 4 generally has a certain distance from the docking socket 3 of the discharge socket 2, the triggering mechanism 8 is mainly arranged between the locking latch 5 at the docking socket 3 and the on-off key 4, thereby realizing the linkage effect as a linkage part.

[0051] As an implementation manner, the on-off key 4, the triggering mechanism 8, and the locking latch 5 form an integral structure. In this way, to realize the change of the locking latch 5 between the locked and released states, a locking latch 5 structure with elastic deformation ability can be adopted, that is, a structure similar to a V-shaped or Y-shaped structure. A slideway for guiding its expansion and clamping is provided in the discharge socket 2, and a restoring force is provided by an elastic member. A clamping or loosening protrusion structure can be formed on the inner wall of the docking socket 3 during two movements in different directions, and it can also realize the change of the two states of locking and releasing the plug 1. Another way is to provide corresponding sockets on the plug 1, and the locking latch 5 can be inserted and withdrawn. When inserted, through two specific directions, a limiting force can be provided to limit the movement of the plug 1 in a direction perpendicular to the surface of the discharge socket 2.

[0052] Further, referring to Figures 1 - 10 , for the above implementation manner in which the on-off key 4 and the triggering mechanism 8 are integrally arranged, an optimized limitation is carried out.

[0053] Referring to Figures 1 - 4, it can be seen that the discharge socket 2 has two jacks for connecting the three-prong plug of ordinary electrical appliances, and a docking socket 3 on the left side specifically for connecting the plug 1 of the charge and discharge wire. There is a raised circular enclosure around the docking socket 3. Refer to Figure 3 and Figure 4 , there are two latch 5 structures rotatably connected to the discharge socket 2 on both sides inside the docking socket 3. As can be seen in the figure, there are locking grooves 7 on both sides of the plug 1. After the plug 1 abuts against the surface of the docking socket 3, the locking end of the latch 5 can just be inserted into the locking groove 7 to achieve locking connection, that is Figure 3 in the state shown in. When releasing, the latches 5 on both sides rotate outwards, and their locking ends fall out of the locking groove 7. At this time, the plug 1 is not restricted and can be separated.

[0054] Refer to Figure 5 , it can be seen that the power switch 4 itself is provided with an upward reset force by four internal compression springs. The power switch 4 in this embodiment also has a two-stage stroke, that is, it is locked in a lower position after being pressed downwards. At this time, it is in the energized state, and the other stage is that it is pushed downwards again and then bounced up and reset by the compression spring, that is, in the power-off state.

[0055] Among them, the latch 5 is a strip-shaped plate structure. Its upper edge is rotatably connected to the discharge socket 2 through a rotating shaft 9 provided, and its lower edge is connected to the discharge socket 2 through a tension spring 6 provided. The tension spring 6 is connected to the lower edge of the latch 5 and provides a force to contract inwards. At this time, the latches 5 on both sides always have a tendency for the upper opening to open outwards and are limited by the trigger mechanism 8.

[0056] The trigger mechanism 8 in this embodiment is an end formed by extending outwards and bending downwards on both sides of the power switch 4, and the surface of this end has an inclined surface. Refer to Figures 5 - 7 , at this time, the state of the latch 5 is just inserted into the locking groove 7, and the contact surface between the end face of the latch 5 and the trigger mechanism 8 is a vertical surface. When the trigger mechanism 8 is lifted, the inclined surface on its end face comes into contact with the latch 5. At this time, after the vertical surface becomes a surface inclined downwards and inwards, the latch 5 can rotate outwards until it fits on the inclined surface. At this time, the latch 5 is out of contact with the locking groove 7, thus achieving the unlocking effect.

[0057] Refer to Figures 8 - 10 , another way is shown in the figure, that is Figures 5 - 7 in, the length of the latch 5 is lengthened and can just be close to the position where the power switch 4 is located. At this time, only by extending a small length of the power switch 4 to both sides can it maintain a linkage relationship with the latch 5.

[0058] And Figures 8 - 10 in, the length of the latch 5 is shorter and it is only near the docking socket 3. Then the power switch 4 extends towards the docking socket 3 and finally forms a T-shaped structure at the end to contact the latch 5. The other principles are the same as the above embodiments.

[0059] The utility model is not limited to the above optional embodiments, and anyone can obtain other various forms of products under the inspiration of the utility model. The above specific embodiments should not be construed as limiting the protection scope of the utility model. The protection scope of the utility model shall be defined by the claims, and the description can be used to interpret the claims.
