[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0037] See also Figure 1-Figure 8 In an embodiment of the present invention, a double-locking interlocking new energy vehicle circuit connector buckle device comprises a first connector 1 connected to the vehicle circuit and a second connector 2 adapted to the first connector 1, and a connector 4 for accessing the vehicle circuit is provided on the side of the first connector 1, and a housing 3 is provided at the bottom of the second connector 2, so that the bottom of the second connector 2 forms an installation chamber;

[0038] The double-locking interlocking new energy vehicle circuit connector buckle device also includes:

[0039] Two assembly plates 10 are symmetrically and movably provided on the first connecting member 1, and the two assembly plates 10 are connected to the elastic kneading mechanism installed on the first connecting member 1, and the elastic kneading mechanism is adapted to the connecting head 4;

[0040] Two groups of longitudinal limiting mechanisms are provided in the installation chamber and are triggered when the assembly plate 10 enters the installation chamber. When the longitudinal limiting mechanism is triggered, the first connecting member 1 and the second connecting member 2 complete the electrical connection action. At the same time, the transmission mechanism provided on the assembly plate 10 drives the instantaneous ejection mechanism provided in the installation chamber to move. The instantaneous ejection mechanism cooperates with the transverse limiting mechanism installed on the assembly plate 10.

[0041] In a specific implementation, force is applied to the elastic kneading mechanism to make the elastic kneading mechanism contact the connecting head 4, and then the first connecting member 1 is inserted into the second connecting member 2. Correspondingly, the two assembly plates 10 enter the installation chamber. After the first connecting member 1 and the second connecting member 2 are connected, the elastic kneading mechanism is released to trigger the longitudinal limiting mechanism. At the same time, the transmission mechanism drives the instantaneous ejection mechanism to move. The instantaneous ejection mechanism cooperates with the transverse limiting mechanism to further enhance the stability of the connection between the first connecting member 1 and the second connecting member 2.

[0042] In summary, through the mutual cooperation between various mechanisms and components, the quick connection function of the first connector 1 and the second connector 2 is realized, and during the connection process, the longitudinal limiting mechanism and the transverse limiting mechanism play a role successively, on the one hand, it can improve the connection accuracy between the first connector 1 and the second connector 2, on the other hand, under the joint action of the transverse limiting mechanism and the longitudinal limiting mechanism, it can effectively ensure the reliability of the stable maintenance of the electrical connection state between the first connector 1 and the second connector 2. Therefore, compared with the traditional connection method (plug-in connection or screw connection), the device has the advantages of convenient connection and high reliability, and is suitable for popularization and use.

[0043] Please refer again Figure 1 and Figure 6 The elastic kneading mechanism includes two fitting parts 9 movably arranged on the first connecting member 1 facing the connecting head 4.

[0046] Please refer again Figure 6 and Figure 7 The longitudinal limiting mechanism includes a first locking column 11 installed on the assembly plate 10 and a limiting plate 21 fixed in the installation chamber. The limiting plate 21 is provided with a limiting groove adapted to the first locking column 11. The limiting groove is arranged in an "L" shape, including a first groove section 2101 and a second groove section 2102 connected to each other.

[0047] When in use, pinch the two fitting parts 9 so that the two fitting parts 9 are close to each other and fit against the connecting head 4. At this time, the two movable plates 8 slide close to each other, the first cylindrical spring 7 is compressed, and the first locking column 11 corresponds to the first groove section 2101. Then, the first connecting part 1 can be inserted into the second connecting part 2, and the first locking column 11 slides along the first groove section 2101. When the first connecting part 1 and the second connecting part 2 are effectively connected, the first locking column 11 reaches the intersection of the first groove section 2101 and the second groove section 2102. Then, the fitting parts 9 is released, the first cylindrical spring 7 rebounds, and the first locking cylinder 11 slides along the second slot section 2102 and finally reaches the end of the second slot section 2102 away from the first slot section 2101. During the sliding of the first locking cylinder 11 along the second slot section 2102, the transmission mechanism drives the instantaneous ejection mechanism to move. After the first locking cylinder 11 reaches the end of the second slot section 2102 away from the first slot section 2101, the instantaneous ejection mechanism drives the lateral limiting mechanism to act, and laterally limit the first connecting member 1 to ensure the stability of the connection between the first connecting member 1 and the second connecting member 2.

The slider 38 is connected to an elastic fitting structure, and the elastic fitting structure cooperates with the transmission mechanism.

[0050] Whenever the first locking cylinder 11 slides away from the first slot section 2101 in the second slot section 2102, the transmission mechanism will drive the elastic sleeve structure to move, and accordingly, the elastic sleeve structure drives the slider 38 to slide on the support arm 2401. After the link plate 19 corresponds to the pulley 25, that is, the first locking cylinder 11 just reaches the end of the second slot section 2102 away from the first slot section 2101, the two second locking cylinders 12 are respectively connected with the two The positioning cylinder 22 corresponds, and at the same time, the elastic fitting structure is triggered, and the sliding seat 24 is pulled to slide in the guide rail 23 through the slider 38 and the support arm 2401, so that the pulley 25 acts on the inclined portion 1901, thereby prompting the connecting plate 19 to give way. After the pulley 25 rolls onto the straight portion 1902, the second locking column 12 is inserted into the positioning cylinder 22 to realize the lateral limiting function, thereby improving the stability of the connection between the first connecting member 1 and the second connecting member 2.

The driven plate 29 is connected to two groups of elastic support members arranged in the installation chamber, the telescopic rod 32 is connected to a boss 33 slidably arranged in the cylinder 31, and the outer periphery of the telescopic rod 32 is sleeved with a fourth column spring 34 and a fifth column spring 35, the head ends of the fourth column spring 34 and the fifth column spring 35 are connected to the boss 33, and the tail ends are connected to the inner wall of the cylinder 31.

[0054] In order to make the following description of the movement process clearer, the rectangular groove is described in detail. The rectangular groove includes a first sliding groove 3701, a second sliding groove 3702, a third sliding groove 3703 and a fourth sliding groove 3704 which are connected to each other.

[0055] After the fitting member 9 is released, the first column spring 7 rebounds, and the transmission mechanism will push the driven plate 29 to move away from the limiting plate 21. Accordingly, the limiting column 3001 slides in the inclined groove 3601 and will slide with the guide plate 36, causing the movable plate 30 to slide on the driven plate 29. At this time, the end of the telescopic rod 32 away from the slider 38 slides in the first slide groove 3701. Therefore, the fourth column spring 34 is compressed. When the inclined portion 1901 corresponds to the pulley 25 and the second locking column 12 corresponds to the positioning cylinder 22, the end of the telescopic rod 32 away from the slider 38 It just moves to the intersection of the first slide groove 3701 and the second slide groove 3702, and then the fourth column spring 34 will rebound, prompting the end of the telescopic rod 32 away from the slider 38 to move along the second slide groove 3702 to the intersection of the second slide groove 3702 and the third slide groove 3703, and the telescopic rod 32 pulls the sliding seat 24 to slide in the guide rail 23 through the slider 38 and the support arm 2401, so that the pulley 25 acts on the inclined portion 1901, thereby prompting the connecting plate 19 to give way, and after the pulley 25 rolls to the straight portion 1902, the second locking column 12 is inserted into the positioning cylinder 22.

[0058] When the first connecting member 1 is connected to the second connecting member 2, the fitting member 9 is released, and after the first cylindrical spring 7 rebounds, the transmission plate 1701 will abut against the driven plate 29 and push the driven plate 29 to slide away from the limiting plate 21, and the third cylindrical spring 28 is compressed;

[0059] When the first connecting member 1 needs to be removed from the second connecting member 2, the screw rod 14 is rotated. Under the guiding action of the guide groove 1001 and the guide block 13, the sleeve 15 and the screw rod 14 are slidably matched, so that the sleeve 15 moves away from the column 16 along the length direction of the assembly plate 10. Then, the sleeve 15 can pull the driven cylinder 17 on the column 16 toward the assembly plate 10 through the connecting rod 18. After the transmission plate 1701 and the driven plate 29 are misaligned, the third column spring 28 will rebound, and accordingly, the driven plate 29 will reset. During this process, the limiting column 3001 slides in the inclined groove 3601 again and will slide with the guide plate 36. At this time, the end of the telescopic rod 32 away from the slider 38 moves along the third slide groove 3703, and the fifth column spring 35 is compressed. After the third cylindrical spring 28 rebounds, the end of the telescopic rod 32 away from the slider 38 moves to the intersection of the third slide groove 3703 and the fourth slide groove 3704, and then the fifth cylindrical spring 35 rebounds, prompting the end of the telescopic rod 32 away from the slider 38 to return to the intersection of the first slide groove 3701 and the fourth slide groove 3704, and the telescopic rod 32 drives the sliding seat 24 to reset, the pulley 25 disengages from the inclined portion 1901 and the straight portion 1902, and the second cylindrical spring 20 rebounds, prompting the second locking column 12 to be pulled out of the positioning cylinder 22, and the lateral limit state is contacted, finally, pinch the two fitting parts 9 until the first locking column 11 moves to the intersection of the first groove section 2101 and the second groove section 2102, so that the first connecting member 1 can be directly removed from the second connecting member 2.
