DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0027] As Figures 1 to 8As shown, this utility model provides a battery box locking mechanism, including a lock box 1, a lock cylinder structure 2 inside the lock box 1, a rotating shaft block 4 driven to rotate by a lock cylinder puller 3, a battery box 5 on one side of the lock cylinder structure 2, a slotted sidewall 6 with an upward opening on the side of the battery box 5 facing the lock cylinder structure 2, a rocker arm base 7 between the lock cylinder structure 2 and the battery box 5, a rocker arm 8 on the rocker arm base 7, and a limiter above the rocker arm 8 for limiting the rocker arm 8. The pressure plate 9 on the base 7 and the rocker arm 8 are rotatably mounted on the rocker arm base 7 via a lever assembly. The rocker arm 8 has a locking end and a triggering end. The locking end of the rocker arm 8 extends toward the battery box 5 and is fitted into the side wall 6 of the slot. The triggering end of the rocker arm 8 extends toward the lock cylinder structure 2 and is located below the rotating shaft block 4. The rotating shaft block 4 is provided with a protrusion mechanism 10. When the rotating shaft block 4 rotates to the unlocking position, the protrusion mechanism 10 presses down on the triggering end of the rocker arm 8, causing the locking end of the rocker arm 8 to lift up and disengage from the side wall 6 of the slot. Figure 4 and Figure 5 As shown, the convex mechanism 10 includes at least one convex joint 11, which is disposed on the bottom surface of the rotating shaft block 4. The convex joint 11 and the rotating shaft block 4 are integrally formed, and the connection position between the convex joint 11 and the rotating shaft block 4 is transitioned by an arc.

[0028] like Figure 2 and Figure 3 As shown, the lever assembly includes a pressure groove 12, a fulcrum groove 13, and a fulcrum post 14. The pressure groove 12 is set on the rocker arm base 7 near the lock cylinder structure 2. The fulcrum groove 13 is set on both sides of the pressure groove 12. The fulcrum post 14 is set on the rocker arm 8 and is rotatably set in the fulcrum groove 13. The pressure plate 9 is set directly above the fulcrum post 14.

[0029] A pin 15 is provided in the pressure groove 12. The pin 15 is located between the fulcrum groove 13 and the trigger end of the swing rod 8. A spring 16 is sleeved on the outside of the pin 15. The two ends of the spring 16 are connected to the bottom surface of the swing rod 8 and the bottom surface of the pressure groove 12, respectively. The swing rod 8 has a hole 17 corresponding to the position of the pin 15. The pin 15 is inserted into the hole 17.

[0030] The two ends of the pressure plate 9 are fixedly installed on the swing arm base 7. The pressure plate 9 is set directly above the fulcrum column 14 to press down the fulcrum columns 14 on both sides of the swing arm 8.

[0031] like Figure 6 As shown, a gap groove 18 is formed on the bottom center of the pressure plate 9 near the battery box 5. The vertical depth of the gap groove 18 is greater than the engagement depth between the engaging end of the swing rod 8 and the side wall 6 of the slot. The engagement depth is the distance that the engaging end of the swing rod 8 needs to be raised to disengage from the side wall 6 of the slot.

[0032] like Figure 1 , Figure 7And Figure 8 As shown in the figure, when the lock core dial unlocks the lock core structure 2, the rotating shaft block 4 in the lock core structure 2 rotates synchronously, thereby driving the convex block 11 on the bottom surface to rotate. Under the circumferential rotation of the convex block 11, the head end of the convex block 11 contacts the trigger end of the swing lever 8 and pushes the trigger end to compress the spring 16 to move downward, thereby making the swing lever 8 rotate around the fulcrum column 14, making the clamping end of the swing lever 8 lift up to disengage from the side wall 6 of the clamping groove, and completing the unlocking of the battery box 5. When the convex block 11 is separated from the trigger end of the swing lever 8 with the continuous rotation of the rotating shaft block 4, the trigger end of the swing lever 8 rises under the rebounding action of the spring 16, at this time the clamping end of the swing lever 8 moves downward to insert into the side wall 6 of the clamping groove to complete the clamping operation again.

[0033] Among them, the gap groove 18 opened on one side of the pressing plate 9 is used for the clamping end of the swing lever 8 to lift up, and the other side of the middle part of the pressing plate 9 abuts against the swing lever 8 to limit the swing lever 8 on the swing lever 8 base. Similarly, a gap can be arranged in the middle of the swing lever 8 to avoid the pressing plate 9.

[0034] The above examples are only exemplary embodiments of the present application, and are not used to limit the present application, the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also regarded as falling within the protection scope of the present application.
