Description

Technical Field

[0001] This utility model relates to a lock, and more particularly to a wireless electric door lock. Background Technology

[0002] The announcement number CN205751983U discloses a connector for ignition switches of motorcycles or electric vehicles. It features an L-shaped connector with an L-shaped folded edge connected to a cover plate. The outer side of the L-shaped straight edge has a barb to restrict the axial movement of the sheath. The inner ring of the sheath has a limiting step that matches the barb. The connector structure is designed to be optimized to accommodate narrow slots. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a wireless electric door lock, which is designed with a narrowed plug plate to form a plug end to adapt to a narrow slot.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This wireless electric door lock includes a rotor, a moving contact piece, a plug, and a mounting base. The rotor includes a body and a plug. The moving contact piece is sleeved on the plug. An elastic element is provided between the moving contact piece and the body. The rotor drives the moving contact piece to rotate. Moving contacts are provided at both ends of the moving contact piece. One end of the plug is bent to form a contact plate. The mounting base includes a connecting part and a plug-in part. The connecting part has a slot for the plug to be inserted and rotated. The connecting part has a groove along the circumference of the slot for the contact plate to be accommodated. The other end of the plug is bent twice to form a plug-in plate. The plug-in plate is narrowed to form a plug-in end. The plug-in part has a mounting cavity for the plug-in plate to be accommodated. The bottom of the mounting cavity has an opening for the plug-in end to be exposed.

[0005] In this design, the connector end is narrowed to fit into narrow slots. The insert plate is bent twice to form a connector plate. The spacing between the two sets of connector plates can be adjusted according to the degree of bending to fit slots with different spacing. The opening restricts the connector end to ensure that the connector end does not shift during insertion and removal.

[0006] Preferably, the contact plate is connected to the mounting base by rivets.

[0007] In this solution, there is no need to design a contact plate that bends and a mounting bracket that snaps together.

[0008] Preferably, the mounting cavity has a first cavity wall and a second cavity wall disposed opposite to each other. The first cavity wall abuts against the plug plate. The plug is provided with a barb. The second cavity wall is provided with a through hole for the barb to be exposed. The wall of the through hole cooperates with the barb.

[0009] In this design, the plug plate is aligned with the first cavity wall to ensure accurate orientation of the plug end, and the barb cooperates with the hole wall to restrict the vertical movement of the plug piece, thus preventing changes in the bending degree of the plug plate during insertion and removal.

[0010] Preferably, the insert and the connector plate are bent on both sides to form a bent plate, and the bent plate has a V-shaped notch at the bend.

[0011] In this design, the bending plate adds lateral support, improving the bending and torsional resistance of the insert. Especially when subjected to vibration or impact, the V-shaped notch prevents stress concentration at the bending point of the insert.

[0012] Preferably, the insert has an arc-shaped notch, which is located at the end of the connection line between the bent plate and the insert.

[0013] In this design, the arc-shaped notch design prevents stress concentration at the endpoints of the connection line between the bent plate and the insert.

[0014] Preferably, it further includes a lock cylinder and a lock shell. The lock cylinder drives the rotor to rotate. The lock cylinder includes a spindle and a radial protrusion. The radial protrusion extends radially along the rotation axis of the spindle. The lock shell includes an inner shell. The inner shell has a mounting hole for the spindle to pass through and rotate. The mounting hole extends radially along the rotation axis of the spindle and has a radial space for the radial protrusion to pass through. The bottom end of the inner shell has a notch for the radial protrusion to enter axially. There is a moving gap between the bottom of the slot and the plug for the plug to move axially along the rotation axis. The insert includes an intermediate plate and a transition plate. The transition plate connects the intermediate plate and the plug plate. The transition plate is inclined relative to the intermediate plate.

[0015] In this design, the compression elastic element provides axial movement space, the radial protrusion enters the notch to complete the assembly of the lock cylinder, and the transition plate is tilted to make way for the movement gap.

[0016] The beneficial effects of this utility model are as follows: the narrowed plug end adapts to narrow slots; the plug plate is bent twice to form a plug plate; the spacing between the two sets of plug plates can be adjusted according to the degree of bending to adapt to slots with different spacings; and the opening restricts the plug end, ensuring that the plug end does not shift during insertion and removal. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description
