When the self-locking device needs to be manually unlocked, the user unlocks the self-locking device by pulling the unlocking pull rope.

[0003] However, in the prior art, when the plastic spring in the self-locking device is damaged, the entire self-locking device needs to be disassembled for repair, which is inconvenient and costly. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in view of the problem in the prior art that when the self-locking device is damaged, it is inconvenient to repair, and a connection structure of an unlocking pull rope and a self-locking device are provided.

[0005] In order to solve the above technical problems, on the one hand, an embodiment of the utility model provides a connection structure for an unlocking pull rope, including a pull rope body, a stopper and a buckle cap, wherein the buckle cap is suitable for being installed on a vehicle body sheet metal part, one end of the pull rope body is suitable for being connected to a self-locking component of a charging base, and the other end of the pull rope body is provided with the stopper, and the stopper is detachably connected to the buckle cap, and the buckle cap is used to pull the pull rope to unlock the self-locking component of the charging base.

[0006] Optionally, the buckle cap is provided with a buckle groove matching the stopper, and the stopper is buckled in the buckle groove. In this embodiment, the buckle groove has an opening for the pull rope body and the stopper to enter. When the stopper enters, the elastic clamping claw is pushed open by applying external force, so that the opening becomes larger, thereby facilitating the movement of the stopper into the buckle groove. After the stopper enters into the buckle groove, the applied external force is removed, so that the elastic clamping claw returns to the initial position under the action of elasticity, thereby reducing the opening and making the stopper buckled in the buckle groove. At the same time, preferably, the elastic force of the clamping claw in the present application constrains the stopper, for example, more than 200N, so that the stopper does not detach from the buckle cap when the pull rope body is pulled by the buckle cap. When the buckle cap is damaged, the user can apply a larger force to remove the buckle cap from the stopper. The control of elastic materials and elasticity is prior art and will not be elaborated here.

[0007] Optionally, the buckle cap has a plurality of clamping claws at one end close to the stopper, the clamping claws are elastic, and the plurality of clamping claws are arranged at intervals and form the buckle groove. In this embodiment, the buckle groove has an opening for the pull rope body and the stopper to enter. When the stopper enters, the elastic clamping claws are pushed away by applying external force, so that the opening becomes larger, thereby facilitating the movement of the stopper into the buckle groove. After the stopper enters into the buckle groove, the applied external force is removed, so that the elastic clamping claws are restored to the initial position under the action of elasticity, thereby reducing the opening and making the stopper buckle into the buckle groove. At the same time, preferably, the elastic force of the clamping claws in the present application constrains the stopper, for example, more than 200N, so that the stopper does not separate from the buckle cap when the pull rope body is pulled by the buckle cap. When the buckle cap is damaged, the user can remove the buckle cap from the stopper by applying a larger force. The control of elastic materials and elasticity is prior art and will not be elaborated here.

[0008] Optionally, a steel sleeve is pressed onto one end of the self-locking assembly of the pull rope body away from the charging seat, and the stopper is clamped between the steel sleeve and the buckle cap.

[0010] Optionally, the stopper is slidably sleeved on the pull rope body. In this embodiment, the stopper is mobile, and the stopper is first installed on the pull rope body, and then the steel sleeve is pressed onto the pull rope body, and it is ensured that it can withstand a force of more than 200N so that it will not fall off when manually pulled; then the buckle cap is buckled into the through hole reserved in the body sheet metal, and then the stopper is moved to the steel sleeve so that one end of the stopper abuts against the steel sleeve, and finally the stopper and the steel sleeve are buckled into the inside of the buckle cap so that the other end of the stopper abuts against the buckle cap to complete the installation. When disassembly is required, the stopper only needs to be removed from the buckle cap to achieve disassembly, which is convenient and quick.

[0011] Optionally, the accommodating cavity extends along the axial direction of the stop member, and the cross-sectional size of the accommodating cavity gradually decreases along the direction from one end of the accommodating cavity close to the steel sleeve to the other end.

[0012] Optionally, the buckle cap has a gripping portion at one end away from the stopper for easy gripping. In this embodiment, the gripping portion can abut against the sheet metal of the vehicle body, and when the pull rope body needs to be pulled, the user unlocks it by pulling the gripping portion.

[0013] According to the connection structure of the unlocking pull rope of this embodiment, the self-locking component is installed on the AC charging seat. When the charging gun is connected to the AC charging seat on the car and charged, the self-locking component can lock and fix the charging gun so that the charging gun cannot be pulled out. During installation, the AC charging seat is arranged on the outside of the body sheet metal, and a through hole is arranged on the body sheet metal. The buckle cap is installed in the through hole. The end of the buckle cap close to the self-locking component extends out of the body sheet metal, and the end of the buckle cap away from the self-locking component is located on the inner side of the body sheet metal. At the same time, the stopper of this embodiment is located on the outside of the body sheet metal. This embodiment sets the stopper and the buckle cap as a detachable connection. When the buckle cap is damaged, there is no need to disassemble the entire self-locking device. It is only necessary to disassemble and separate the stopper and the buckle cap. Maintenance is convenient and maintenance costs can be reduced.

[0014] On the other hand, an embodiment of the present invention provides a self-locking device, including a self-locking component and the above-mentioned connection structure of the unlocking pull rope.
