Technical Field
[0001] The present application relates to the technical field of locking structures, and in particular to an adapter locking structure. Background Art
[0002] With the advancement of technology and the enhancement of environmental awareness, the use of new energy vehicles has become more and more popular. New energy vehicles do not need to use fuel to drive, which is safer and more environmentally friendly. New energy vehicles are driven by electricity, and the vehicle is charged using a charging gun at a set charging pile. The charging gun is connected to the charging pile through a cable. With the development of new energy vehicles, different countries and regions have set up charging interfaces with different standards. China has also announced a new technical standard for electric vehicle charging interfaces, named "ChaoJi". Compared with the existing charging interface standards, the uniqueness of the "ChaoJi" standard lies in its powerful charging capacity. Not only that, it is smaller in size and more powerful, ensuring that electric vehicles can be charged quickly and safely while maintaining compatibility.

New energy vehicles do not need to use fuel to drive, which is safer and more environmentally friendly. New energy vehicles are driven by electricity, and the vehicle is charged using a charging gun at a set charging pile. The charging gun is connected to the charging pile through a cable. With the development of new energy vehicles, different countries and regions have set up charging interfaces with different standards. China has also announced a new technical standard for electric vehicle charging interfaces, named "chaoji". Compared with the existing charging interface standards, the uniqueness of the chaoji standard lies in its powerful charging capacity. Not only that, it is smaller in size and more powerful, ensuring that electric vehicles can be charged quickly and safely while maintaining compatibility.
[0004] Existing cars produced according to the new charging interface standard have a "ChaoJi" vehicle socket. Since most domestic charging guns are manufactured according to the old standard, the "ChaoJi" vehicle socket cannot match the charging gun, and an adapter needs to be set up to facilitate the charging process of the car.
[0005] The existing charging gun and adapter are usually connected by snap-fitting. When using the charging gun with the adapter to charge the car, the adapter with the end of the charging gun snap-fitted is inserted into the vehicle socket, and the adapter is locked by the electronic lock inside the vehicle socket, so that the position between the vehicle socket and the adapter is relatively fixed, which is convenient for charging the car. However, the reliability of the snap-fitting between the adapter and the charging gun is poor, which can easily cause the adapter and the charging gun to separate, and thus easily affect the safety of the adapter. Utility Model Content
[0006] In order to improve the reliability of the connection between the adapter and the charging gun, thereby improving the safety of the adapter during use, the present application provides an adapter locking structure.
[0007] The present application provides an adapter locking structure, which adopts the following technical solution:
[0008] An adapter locking structure includes a charging gun and an adapter, wherein the charging gun is provided with a mechanical lock hook, the adapter is provided with a lock slot, the mechanical lock hook is snap-fitted into the lock slot, and the adapter is provided with a locking assembly, which can cooperate with a vehicle socket to prevent the mechanical lock hook from escaping from the lock slot.
[0009] By adopting the above technical solution, the mechanical lock hook and the lock slot are locked together, which helps to lock the charging gun and the adapter. During the use of the charging gun, the adapter connected to the charging gun needs to be inserted into the vehicle socket, so that the locking assembly can press the mechanical lock hook with the cooperation of the vehicle socket, which helps to prevent the mechanical lock hook from lifting out of the lock slot, thereby improving the reliability of the connection between the adapter and the charging gun and improving the safety of the adapter during use.
[0010] In a specific feasible implementation scheme, the locking assembly includes a fixed shell, a locking rod, a limit block and a return spring. The fixed shell is arranged on the adapter, and insertion holes are arranged on the opposite side walls of the fixed shell along the axial direction of the adapter. The locking rod is movably arranged in the insertion hole, the limit block is fixedly sleeved on the locking rod and located in the fixed shell, the return spring is sleeved on the locking rod and located in the fixed shell, the end of the return spring away from the charging gun abuts against the limit block, and the end of the return spring close to the charging gun abuts against the inner wall of the fixed shell, and the locking rod can prevent the mechanical lock hook from falling out of the lock groove with the cooperation of the vehicle socket.
[0011] By adopting the above technical solution, when the adapter connected to the charging gun is inserted into the vehicle socket, one end of the locking rod contacts the end face of the vehicle socket, so that the locking rod moves along the insertion hole in the fixed shell toward the charging gun, so that the end of the locking rod away from the vehicle socket moves above the mechanical lock hook and presses the mechanical lock hook, which helps to prevent the mechanical lock hook from lifting out of the lock slot, thereby improving the reliability of the connection between the adapter and the charging gun and improving the safety of the adapter during use.
[0012] In a specific possible implementation manner, a guide portion is provided at the end of the locking rod, and the guide portion is used to prevent the end of the locking rod from interfering with the mechanical locking hook.
[0013] By adopting the above technical solution, the guide portion helps to prevent the end of the locking rod from colliding with the mechanical lock hook during movement, causing the locking rod to be unable to move above the mechanical lock hook, thereby ensuring the smoothness of the locking rod moving above the mechanical lock hook, and further ensuring that the locking rod can prevent the mechanical lock hook from being lifted out of the lock slot.
[0014] In a specific possible implementation manner, a limiting frame for limiting the locking rod is provided on the mechanical locking hook, and an opening for inserting the locking rod is provided on the limiting frame.
[0015] By adopting the above technical solution, when the locking rod is inserted into the limit frame through the opening, the limit frame helps to limit the locking rod, thereby helping to improve the stability of the locking rod pressing against the mechanical lock hook, and then helping to improve the stability of the mechanical lock hook and the lock slot, further improving the reliability of the connection between the adapter and the charging gun, and further improving the safety of the adapter during use.
[0016] In a specific possible implementation manner, the limiting frame is provided with an introduction portion, and the introduction portion is an arc-shaped structure and is located at two side edges of the opening.
[0017] By adopting the above technical solution, the introduction portion can cooperate with the guide portion at the end of the locking rod, thereby helping to improve the smoothness of the locking rod being inserted into the limiting frame.
[0018] In a specific possible implementation manner, one end of the locking rod is provided with an abutment block for abutting against the mechanical locking hook.
[0019] By adopting the above technical solution, when the locking rod is inserted into the limit frame, the abutment block helps to cooperate with the locking rod to press the two adjacent sides of the mechanical lock hook, preventing the mechanical lock hook from lifting out of the lock slot, thereby helping to further improve the stability of the locking connection between the mechanical lock hook and the lock slot, further improve the reliability of the connection between the adapter and the charging gun, and further improve the safety of the adapter during use.
[0020] In a specific possible implementation scheme, a guide protrusion is provided on the hole wall of the through hole, the length direction of the guide protrusion is parallel to the axial direction of the through hole, and the locking rod is provided with a guide groove for engaging with the guide protrusion.
[0021] By adopting the above technical solution, the engagement of the guide protrusion and the guide groove helps to guide the movement of the locking rod, and at the same time helps to prevent the locking rod from rotating during the movement, thereby helping to improve the accuracy of the abutment block's pressing position on the mechanical lock hook, and further helping to improve the pressing effect of the abutment block on the mechanical lock hook.
[0022] In a specific possible implementation manner, a plurality of guide protrusions are arranged in a circular array with the axis of the through hole as the center line, and a plurality of guide grooves are arranged in a circular array with the axis of the locking rod as the center line.
[0023] By adopting the above-mentioned technical scheme, the position setting of the guide protrusion and the guide groove helps to improve the uniformity of the circumferential force applied to the locking rod during movement, thereby helping to avoid as much as possible the locking rod from getting stuck during movement in the through hole, and further helping to improve the smoothness of movement of the locking rod in the through hole.

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.
[0035] Embodiment 1:
[0036] The present application embodiment discloses an adapter locking structure, referring to Figure 1 and Figure 2 , comprising a lockingly connected charging gun 1 and an adapter 2, a mechanical lock hook 3 is fixedly installed on the outer wall of the end of the charging gun 1 close to the adapter 2, a lock slot 4 is provided on the outer wall of the end of the adapter 2 close to the charging gun 1, and the mechanical lock hook 3 is clamped and fixed in the lock slot 4. When the adapter 2 is connected to the charging gun 1, the mechanical lock hook 3 is clamped and fixed in the lock slot 4, so that the charging gun 1 and the adapter 2 are locked and connected.
[0037] Reference Figure 2 and Figure 3 The adapter 2 is provided with a locking assembly 5, which includes a fixed housing 51, a locking rod 52, a stopper 53 and a return spring 54. The fixed housing 51 is fixedly mounted on the adapter 2. The opposite side walls of the fixed housing 51 are provided with through holes 6, and the two through holes 6 are arranged along the axial direction of the adapter 2. The locking rod 52 is movably placed in the fixed housing 51 and passes through the two through holes 6. The end of the locking rod 52 close to the charging gun 1 has a guide portion 7. The stopper 53 is fixedly sleeved on the circumference of the locking rod 52 and is located on the side of the fixed housing 51 away from the charging gun 1. The return spring 54 is sleeved on the locking rod 52 and is located on the side of the fixed housing 51 close to the charging gun 1. The end of the return spring 54 away from the charging gun 1 abuts against the stopper 53, and the end of the return spring 54 close to the charging gun 1 abuts against the inner wall of the fixed housing 51.
[0038] Reference Figure 2 and Figure 4 After the adapter 2 is locked and connected with the charging gun 1, when the charging gun is used to charge the vehicle, the adapter 2 needs to be inserted into the vehicle socket. During the process of gradually inserting the adapter 2 into the vehicle socket, one end of the locking rod 52 will contact the end surface of the vehicle socket, and as the adapter 2 is inserted, the locking rod 52 moves relative to the fixed housing 51 toward the charging gun 1 under the contact of the end surface of the vehicle socket, and at the same time, the limit block 53 presses the return spring 54, so that the return spring 54 is gradually compressed.
[0039] Reference Figure 2 and Figure 4 When the adapter 2 is fully inserted into the vehicle socket, the electronic lock 14 inside the vehicle socket locks the adapter 2. At the same time, the end of the lock rod 52 away from the vehicle socket moves to the upper surface of the mechanical lock hook 3 under the resistance of the end surface of the vehicle socket and presses the mechanical lock hook 3, thereby preventing the mechanical lock hook 3 from being lifted out of the lock slot 4, thereby improving the reliability of the connection between the adapter and the charging gun and improving the safety of the adapter during use.
[0040] Reference Figure 2 and Figure 4 In the process of the end of the locking rod 52 away from the vehicle socket moving to the upper surface of the mechanical lock hook 3, the guide portion 7 helps to prevent the locking rod 52 from colliding with the side of the mechanical lock hook 3, thereby causing the end of the locking rod 52 away from the vehicle socket to be unable to move to the upper surface of the mechanical lock hook 3, thereby ensuring the smoothness of the locking rod 52 moving to the top of the mechanical lock hook 3, and further ensuring that the locking rod 52 can prevent the mechanical lock hook 3 from being lifted out of the lock slot 4.
[0041] Reference Figure 2 and Figure 4 A limit frame 8 is fixedly mounted on the upper surface of the mechanical lock hook 3 , and an opening 9 is formed on the side of the limit frame 8 facing the adapter 2 , and both side edges of the opening 9 of the limit frame 8 have arc-shaped introduction portions 10 .
[0042] Reference Figure 2 and Figure 4 When the end of the locking rod 52 away from the vehicle socket gradually moves to the upper surface of the mechanical lock hook 3, the guide portion 7 at one end of the locking rod 52 will pass through the opening 9 and be inserted into the limit frame 8 under the guidance of the introduction portion 10, so that the limit frame 8 limits the end of the locking rod 52 located on the upper surface of the mechanical lock hook 3, thereby helping to improve the stability of the locking rod 52 pressing the mechanical lock hook 3, and then helping to improve the stability of the mechanical lock hook 3 and the lock groove 4, further improving the reliability of the connection between the adapter and the charging gun, and further improving the safety of the adapter during use.
[0043] The implementation principle of the embodiment of the present application is: the mechanical lock hook 3 is clamped and fixed into the lock slot 4, so as to lock and connect the charging gun 1 and the adapter 2. When the charging gun is used to charge the vehicle, the adapter 2 needs to be inserted into the vehicle socket. During the process of gradually inserting the adapter 2 into the vehicle socket, one end of the lock rod 52 will contact the end face of the vehicle socket, and as the adapter 2 is inserted, the lock rod 52 moves relative to the fixed housing 51 toward the charging gun 1 under the contact of the end face of the vehicle socket, and at the same time, the limit block 53 presses the reset spring 54, so that the reset spring 54 is gradually compressed.
[0044] When the adapter 2 is fully inserted into the vehicle socket, the electronic lock 14 inside the vehicle socket locks the adapter 2. At the same time, the end of the locking rod 52 away from the vehicle socket moves to the upper surface of the mechanical lock hook 3 under the resistance of the end face of the vehicle socket and presses the mechanical lock hook 3, thereby preventing the mechanical lock hook 3 from lifting out of the lock slot 4, thereby improving the reliability of the connection between the adapter and the charging gun and improving the safety of the adapter during use.
[0045] After the vehicle is charged, the electronic lock 14 releases the lock on the adapter 2, and the user pulls the adapter 2 out of the vehicle socket. Under the elastic force of the reset spring 54 itself, the reset spring 54 drives the limit block 53 and the lock rod 52 to reset, so that the lock rod 52 no longer presses the mechanical lock hook 3.
[0046] Embodiment 2:
[0047] Reference Figure 5 and Figure 6 The difference between Example 2 and Example 1 is that an abutment block 11 is fixedly mounted on one end of the locking rod 52 close to the guide portion 7. In this embodiment, the abutment block 11 is arranged in a semi-circular shape. When the adapter 2 is fully inserted into the vehicle socket, the end of the locking rod 52 away from the vehicle socket moves to the upper surface of the mechanical lock hook 3 and presses the mechanical lock hook 3. At the same time, the abutment block 11 presses the side of the mechanical lock hook 3 synchronously, so that the mechanical lock hook 3 can be prevented from being lifted out of the lock slot 4 under the joint action of the locking rod 52 and the abutment block 11, further improving the stability of the mechanical lock hook 3 and the lock slot 4, further improving the reliability of the connection between the adapter and the charging gun, and improving the safety of the adapter during use.
[0048] Reference Figure 6 A plurality of guide protrusions 12 are fixedly mounted on the wall of each through hole 6, and the plurality of guide protrusions 12 are arranged in a circular array with the axis of the through hole 6 as the center line, and the length direction of each guide protrusion 12 is parallel to the axial direction of the through hole 6; a plurality of guide grooves 13 are opened on the circumferential outer wall of the locking rod 52, and the plurality of guide grooves 13 are arranged in a circular array with the axis of the locking rod 52 as the center line, and the length direction of each guide groove 13 is parallel to the axial direction of the locking rod 52.
[0049] Reference Figure 6During the movement of the lock rod 52, the guide protrusion 12 moves in a directional manner in the guide groove 13, thereby helping to prevent the lock rod 52 from rotating during the movement, thereby helping to improve the accuracy of the abutment block 11 pressing the mechanical lock hook 3, and improving the abutment block 11 pressing the mechanical lock hook 3. The annular array arrangement of the guide protrusion 12 and the guide groove 13 helps to improve the uniformity of the circumferential force of the lock rod 52 during the movement, thereby helping to avoid the lock rod 52 from getting stuck during the movement in the insertion through hole 6, thereby helping to improve the smoothness of the movement of the lock rod 52 in the insertion through hole 6.
[0050] In Example 2 of the present application, the implementation principles of the same parts as those of Example 1 are not repeated here. The difference between the implementation principles of the two is that when the adapter 2 is fully inserted into the vehicle socket, the end of the locking rod 52 away from the vehicle socket moves to the upper surface of the mechanical lock hook 3 and presses the mechanical lock hook 3. At the same time, the abutment block 11 synchronously presses the side of the mechanical lock hook 3, so that under the joint action of the locking rod 52 and the abutment block 11, the mechanical lock hook 3 can be prevented from lifting out of the lock slot 4, further improving the stability of the card connection and locking of the mechanical lock hook 3 and the lock slot 4, further improving the reliability of the connection between the adapter and the charging gun, and improving the safety of the adapter during use.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
