[0002] New energy vehicle charging connectors are subject to different standards, including Chinese, European, Tesla, and Japanese. Charging guns and charging docks meeting these standards cannot be directly connected and require an adapter. Existing adapters typically feature mechanical locking mechanisms, such as latches. During charging, the two latches on the adapter engage the charging gun and charging dock, respectively, to ensure locking. However, existing adapters do not have a sequential order for locking and unlocking. Under some standards, such as the Tesla standard, incorrect locking and unlocking sequences can lead to undesirable situations, such as hot plugging and unplugging. Utility Model Content

[0031] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present utility model.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way constitutes any limitation to the present utility model and its application or use.

[0033] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0034] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0035] As Figure 1-2 shown, an embodiment of the present utility model provides an adapter, including a body. Opposite ends of the body respectively form a gun end 2 and a socket end 3. On the outer sides of the gun end 2 and the socket end 3 of the body, a first latch 1 and a second latch 4 that are respectively clamped and matched with a charging socket 30 and a charging gun 20 are pivotally connected. Opposite ends of the first latch 1 and the second latch 4 are respectively a locking end and a pressing end. Inside the body in the insertion direction, there are provided:

[0036] a first elastic telescopic structure, on which there is a groove 51 for avoiding the pressing end of the first latch 1, i.e., the first pressing end 12. And one end of the first elastic telescopic structure is located on the insertion path of the charging gun 20. When the charging gun 20 is inserted into the socket end 3, it pushes one end of the first elastic telescopic structure, so that the groove 51 and the pressing end of the first latch 1, i.e., the first pressing end 12, are switched from a misaligned setting to a relative setting, so as to unlock the pressing end of the first latch 1, i.e., the first pressing end 12;

[0037] a second elastic telescopic structure, one end of which is located on the insertion path of the charging socket 30. When the charging socket 30 is inserted into the gun end 2, it pushes one end of the second elastic telescopic structure, so that the other end of the second elastic telescopic structure moves to the inside of the pressing end of the second latch 4, i.e., the second pressing end 42, to prevent the pressing end of the second latch 4, i.e., the second pressing end 42, from being unlocked.

[0038] This embodiment adopts a pure mechanical structure method. By jointly defining the unlocking sequence of the first latch 1 and the second latch 4 through the first elastic telescopic structure and the second telescopic structure, the insertion and extraction sequences of the charging gun 20 and the charging socket 30 are strictly limited. That is, in this embodiment, the insertion and extraction sequence is: the charging gun 20 is inserted into the socket end 3 - the gun end 2 is inserted into the charging socket 30 - the gun end 2 is pulled out from the charging socket 30 - the charging gun 20 is pulled out from the socket end 3. The overall structure is reliable in use and has a relatively low manufacturing cost, and can effectively prevent abnormal situations such as live plugging and unplugging caused by incorrect locking and unlocking sequences.

[0039] Further, in order to realize the installation of the first elastic telescopic structure and the second elastic telescopic structure, and isolate the first elastic telescopic structure and the second elastic telescopic structure from other structures inside the adapter, as Figure 1As shown in the figure, in this embodiment, a first sliding cavity 6 and a second sliding cavity 9 are provided in the body, both extending along the insertion direction. The first elastic telescopic structure and the second elastic telescopic structure are respectively slidably installed in the first sliding cavity 6 and the second sliding cavity 9, and one end of the first elastic telescopic structure and the second elastic telescopic structure respectively extends to the insertion path of the charging gun 20 or the charging seat 30 after protruding from the corresponding sliding cavity.

[0040] Obviously, in this embodiment, the above-mentioned first sliding cavity 6 and second sliding cavity 9 are respectively arranged close to the first latch 1 and the second latch 4, and one end of the first elastic telescopic structure is located on the insertion path of the charging gun 20, and one end of the second elastic telescopic structure is located on the insertion path of the charging seat 30.

[0041] Specifically, as a simple and reliable structure, as Figure 1 shown, in this embodiment, the first elastic telescopic structure includes a first sliding member 5 and a first elastic member 7. One end of the first sliding member 5 extends to the insertion path of the charging gun 20 after protruding from the first sliding cavity 6, and the other end abuts against the first elastic member 7 installed in the first sliding cavity 6.

[0042] Specifically, similarly as a simple and reliable structure, as Figure 1 shown, in this embodiment, the second elastic structure includes a second sliding member 8 and a second elastic member 10. One end of the second sliding member 8 extends to the insertion path of the charging seat 30 after protruding from the second sliding cavity 9, and the other end extends out of the second sliding cavity 9 and moves to the inside of the pressing end of the second latch 4, that is, the second pressing end 42, after being pushed by the charging seat 30. The second elastic member 10 is located in the second sliding cavity 9 and is installed outside the second sliding member 8. Protrusions, namely a first protrusion 81 and a second protrusion 91, are respectively provided on the outside of the second sliding member 8 and the inner wall of the second sliding cavity 9. Both ends of the second elastic member 10 abut against the corresponding protrusions.

[0043] As Figure 1 shown, in this embodiment, both the first elastic member 7 and the second elastic member 10 are compression springs extending along the sliding direction. In other embodiments, the first elastic member can also be a rubber block or other elastic devices, and the second elastic member can also be a rubber tube or other devices that can be installed on the second sliding member and have axial telescopic ability. However, when designing specifically, the radial and axial deformation strokes and deformation abilities of the rubber tube should be considered.

[0044] Furthermore, in order to make the cooperation between the first elastic member 7 and the first sliding member 5 and the first sliding cavity 6 more stable, and to facilitate assembly and the position limitation of the first sliding member 5, as Figure 1As shown, in this embodiment, two ends of the first elastic member 7 are respectively abutted against the other end of the first sliding member 5 and one end of the first sliding cavity 6 close to the gun end 2, and guide posts 61 are provided at the other end of the first sliding member 5 and one end of the first sliding cavity 6 close to the gun end 2. Two ends of the first elastic member 7 are respectively inserted and connected with corresponding guide posts 61.

[0045] Further, in order to adapt to the spacing existing in the structural design and enable the groove 51 to better cooperate with the pressing end of the first latch 1, i.e., the first pressing end 12, as Figure 1 shown, in this embodiment, an interference rib 13 adapted to be inserted into the groove 51 is provided inside the pressing end of the first latch 1, i.e., the first pressing end 12. When the groove 51 and the interference rib 13 are switched from a dislocation setting to a relative setting, pressing the pressing end of the first latch 1, i.e., the first pressing end 12, unlocks the first latch 1.

[0046] During specific application, as Figure 1 shown, first, the first sliding member 5 of the first elastic telescopic structure is inserted into the first sliding cavity 6, then the first elastic member 7 is sleeved on the guide post 61 of the first sliding member 5, then the second elastic member 10 is inserted onto the second sliding member 8 and then loaded into the second sliding cavity 9, and finally the gun end 2 is assembled onto the adapter, thereby completing the assembly of the adapter and the first elastic telescopic structure and the second elastic telescopic structure. At this time, the first latch 1 is in a locked state, and the second latch 4 is in a state where it can be unlocked and allowed to be pressed.

[0047] When charging is required, since the interference rib 13 inside the first pressing end 12 is not opposite to the groove 51 on the first sliding member 5, the first latch 1 cannot be pressed and is in a locked state, so the gun end 2 of the adapter cannot be inserted into the charging base 30. Therefore, only the charging gun 20 can be first inserted into the socket end 3 of the adapter. After the charging gun 20 is inserted into the socket end 3 of the adapter, the first sliding member 5 is pushed by the charging gun 20 and slides towards the gun end 2 of the adapter until the locking end of the second latch 4, i.e., the second locking end, is locked and connected with the charging gun 20. At this time, the interference rib 13 inside the first pressing end 12 is opposite to the groove 51 on the first sliding member 5, and the first latch 1 can be unlocked and allowed to be pressed. At this time, it is allowed to insert the charging base 30 into the socket end 3 of the adapter. After the charging base 30 is inserted into the socket end 3 of the adapter, the second sliding member 8 is pushed by the charging base 30 and slides towards the socket end 3 of the adapter until the locking end of the first latch 1, i.e., the first locking end, is locked and connected with the charging base 30. One end of the second sliding member 8 close to the socket end 3 extends into the pressing path of the second pressing end 42, so that the second latch 4 cannot be pressed and is locked, and the charging gun 20 cannot be pulled out of the adapter. Thus, the charging operation process is completed, as Figure 2 shown. That is, during charging, in this embodiment, the operation can only be carried out in the order of the charging gun 20 being inserted into the socket end 3 - the gun end 2 being inserted into the charging base 30.

[0048] When charging is completed and the adapter is removed, the charging gun 20 cannot be pulled out of the adapter first because the second lock buckle 4 is locked, and the first lock buckle 1 is still in an unlockable state. Therefore, the first pressing end 12 can only be pressed to release the locking connection of the first locking end 11 to the charging seat 30, and then the gun end 2 of the adapter is pulled out from the charging seat 30. At this time, the second sliding member 8 returns to its initial position under the elastic force of the second elastic member 10, that is, the end of the second sliding member 8 close to the seat end 3 is out of the pressing path of the second pressing end 42, and the second sliding member 8 is released. The second lock catch 4 can be unlocked and pressed, and then the second pressing end 42 is pressed to release the locking connection between the second locking end 41 and the charging gun 20. At this time, the charging gun 20 can be pulled out of the base end 3 of the adapter. The first sliding member 5 returns to its initial position under the elastic force of the first elastic member 7. The interference rib 13 on the inner side of the first pressing end 12 does not correspond with the groove 51 on the first sliding member 5, so the first pressing end 12 cannot be pressed, and the first lock catch 1 is locked. The adapter now returns to its initial state. That is, when charging is completed, this embodiment only allows the gun end 2 to be pulled out of the charging base 30 and the charging gun 20 to be pulled out of the base end 3 in this order.

[0049] It can be understood and easily obtained based on the above embodiments that, in another embodiment, by swapping and adjusting the positions of the first elastic telescopic structure and the second elastic telescopic structure, another plug-in and pull-out sequence of the charging gun and the charging base opposite to the above embodiment can be obtained, that is, the gun end is inserted into the charging base - the charging gun is inserted into the base end - the charging gun is pulled out of the base end - the gun end is pulled out of the charging base. The specific arrangement of the first elastic telescopic structure and the second elastic telescopic structure is as follows: the first elastic telescopic structure has a groove for avoiding the pressing end of the second lock buckle, and one end of the first elastic telescopic structure is located on the insertion path of the charging base. When the charging base is inserted into the gun end, it pushes one end of the first elastic telescopic structure so that the groove and the pressing end of the second lock buckle are switched from a staggered setting to a relative setting, so that the pressing end of the second lock buckle is unlocked; one end of the second elastic telescopic structure is located on the insertion path of the charging gun. When the charging gun is inserted into the base end, it pushes one end of the second elastic telescopic structure so that the other end of the second elastic telescopic structure moves to the inner side of the pressing end of the first lock buckle to prevent the pressing end of the first lock buckle from being unlocked. Obviously, at this time, the first sliding cavity and the second sliding cavity are respectively arranged close to the second lock and the first lock, one end of the first elastic telescopic structure is located on the insertion path of the charging seat, and one end of the second elastic telescopic structure is located on the insertion path of the charging gun.

[0050] With reference to the structure and principle of this embodiment, since the structure and principle of this other embodiment can be easily known to those skilled in the art and does not produce innovative technologies beyond this solution and conventional technologies, the relevant structural drawings and more detailed introductions are no longer shown.

Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present utility model.
