Description

Electric motor car electronic type support lock

Technical field:

The utility model electric motor car electronic type support lock relates to the electric motor car electronic type field of lockset that installs additional on the electric motor car support.

Background technology:

Owing to only install mechanical lock additional on the fuse-box in the brake of electric motor car front-wheel or trailing wheel general in the electric motor car, but such lockset is easily knocked open by the thief, and make electric motor car stolen, therefore, except after installing lockset additional on electric motor car front-wheel, the trailing wheel, also should install lockset additional, in case electric motor car is stolen in other position designs of electric motor car.

Summary of the invention:

The purpose of this utility model provides a kind of electric motor car electronic type support lock, after the electromagnetic coil energising in the electric motor car electronic type support lock, then the dead bolt that is connected with electromagnet is just withdrawn and is withdrawed from the lockhole of rotation shank of the key, then rotates shank of the key and can move with the support transverse tube, realizes purpose by bike, otherwise, after the outage, under self-locking spring promotes, after dead bolt stretches into lockhole, support can not be rotated, and the cyclist can reach the purpose of locking support.

A kind of electric motor car electronic type support lock, electric motor car electronic type support lock is by rotating shank of the key, dead bolt, lock body, electromagnetic coil, electromagnet, end cap, forming from locking plate, self-locking spring and stage clip, and the axis of rotation of rotation shank of the key is welded in the shank of the key; Be coated with axis of rotation in the round tube hole that open at the lock body center, lock body is fixed on the electromobile frame; Electromagnetic coil is sleeved on the electromagnet that dead bolt is housed, and electromagnetic coil and electromagnet are arranged in the electromagnetic coil and the electromagnet mounting groove of lock body; End cap by screw on lock body; The spring of self-locking spring is worn on the self-locking spring axle that is contained in lock body, the self-locking spring two ends respectively hook be contained in lock body on locking plate; Stage clip is installed on the electromagnet.

The utility model electric motor car electronic type support lock working principle of design and structure thereof are described as follows:

When the cyclist starts electric switch with key, then the power line of electromagnetic coil is connected power supply, under the effect of energising electromagnetic coil, the electromagnet withdrawal, electromagnet drives coupled dead bolt withdrawal, make dead bolt leave the rotation shank of the key shank of the key in lockhole, the support transverse tube that then is installed in the interior circular groove of rotary handle rotates around the support fixed axis clockwise, the shank of the key rotation of driven rotary shank of the key, the axis of rotation of rotation shank of the key clockwise rotates simultaneously, and rotating counterclockwise from locking plate on the electromagnet makes the electromagnet self-locking, do not do transverse movement, the cyclist can ride this moment; Otherwise, when the electromagnetic coil on the electromagnet cuts off the power supply, support rotates counterclockwise to be propped up, and the rotation shank of the key also rotates counterclockwise, and the self-locking sheet is locked on the electromagnet, dead bolt is under the promotion of stage clip, insert in the lockhole of rotation shank of the key, the shank of the key that then rotates shank of the key can not rotate, and circular groove is installed on the support transverse tube in the rotation shank of the key, make the support transverse tube not realize lock function around the rotation of support fixed axis to support.

This electric motor car electronic type support lock advantage is that unlatching and locking are all very convenient, reliable, when by bike, then can guarantee cyclist's safety.
