Description

Anti-theft device of electric bicycle

Technical Field

The invention relates to the field of electric vehicle theft prevention, in particular to an anti-theft device of an electric bicycle.

Background

An electric bicycle is a mechatronic personal transportation tool which takes a storage battery as auxiliary energy and is provided with a motor, a controller, the storage battery, a rotating handle brake handle and other operating components and a display instrument system on the basis of a common bicycle, and people often refer to the electric bicycle as an electric vehicle in daily life.

At present, patent document with publication number CN104828177A discloses an anti-theft device for an electric vehicle, which is disposed at a foot support of the electric vehicle, and locks a limiting block through a locking mechanism, so that the limiting block blocks the foot support from being supported. Although this kind of anti-theft device can improve the theftproof effect of electric motor car to a certain extent, this kind of anti-theft device does not carry out the theftproof setting with rim department, if the person of stealing destroys the heel brace, the electric motor car can be pushed away by the light and easy of the person of stealing the car, leads to certain economic loss for the victim, leads to the stolen phenomenon of electric motor car frequently easily.

Disclosure of Invention

The invention aims to provide an anti-theft device capable of effectively improving the anti-theft effect of an electric vehicle, and a thief can open the anti-theft device only by opening a fixed lock and a locking lock simultaneously, so that the anti-theft effect of the electric vehicle is effectively improved.

The technical purpose of the invention is realized by the following technical scheme:

the anti-theft device of an electric bicycle is arranged at the rear wheel of an electric bicycle body and comprises a fixed cylinder, a receiving cylinder and a locking rod, wherein the fixed cylinder is fixed at the lower end of a pedal plate at the side end of the rear wheel, a hole in the fixed cylinder is a stepped hole, and a fixed lock is arranged on the fixed cylinder; the receiving cylinder is fixed at the lower end of the pedal plate at the other end of the rear wheel, a hole in the receiving cylinder is also a stepped hole, and the receiving cylinder is provided with a locking lock; the both ends of check lock pole are provided with fixed plate and locking plate respectively, the fixed plate sets up in the solid fixed cylinder, and the fixed plate is greater than the minimum department of ladder hole in the solid fixed cylinder, the locking plate is established in the receiving cylinder, and the locking plate is less than the minimum department of ladder hole in the receiving cylinder, fixedly connected with spring between the one end of keeping away from the receiving cylinder on the fixed plate and the solid fixed cylinder.

Through adopting above-mentioned technical scheme, when the electric motor car locks, the cyclist pulls out the check lock lever and inserts the inside of receiving a section of thick bamboo with the locking plate, then use the locking lock to lock the locking plate in the inside of solid fixed cylinder, the locking plate lock is when receiving a section of thick bamboo, the fixed plate is locked between fixed plate and solid fixed cylinder notch ladder, the check lock lever is located in the middle of the rim always, thereby do not withdraw the check lock lever in the solid fixed cylinder the electric motor car can not ride away, if the thief wants to steal the car, need open two locks of solid fixed lock and locking lock simultaneously, when the electric motor car unblanks, open solid fixed lock and lock the automatic check lock lever of retrieving of locking lock spring in the solid fixed cylinder.

The invention is further configured to: the fixing lock and the locking lock both use a lock with a clamp spring and a locking elastic sheet.

Through adopting above-mentioned technical scheme, the locking shell fragment of two kinds of locks above can be with the fine pinning of fixed plate or locking plate, and the advantage of this kind of lock lies in the tool to lock and has certain elasticity, if want to pry open with smallclothes such as steel wire and have certain degree of difficulty, this also indirect theftproof effect that has improved anti-theft device.

The invention is further configured to: the fixed cylinder is provided with a pull plate groove, the fixed plate is fixedly provided with a pull plate, and the pull plate penetrates through the pull plate groove and extends out of the fixed cylinder.

By adopting the technical scheme, the locking rod can be more conveniently stretched back and forth by a rider through the pulling plate, and the locking and unlocking of the rider are facilitated.

The invention is further configured to: and a round handle is fixedly arranged at one end of the pull plate extending out of the pull plate groove.

Through adopting above-mentioned technical scheme, through setting up the round handle for the rider is more convenient exerts the strength to the arm-tie, thereby can be more succinct tensile check lock pole.

The invention is further configured to: the keys used by the fixed lock and the locking lock are different.

Through adopting above-mentioned technical scheme, the key of two kinds of locks is inequality to increase the degree of difficulty of unblanking of car thief, guaranteed this anti-theft device's theftproof effect.

The invention is further configured to: the fixed cylinder and the receiving cylinder are both circular cylinders.

Through adopting above-mentioned technical scheme, circular cylinder more is favorable to the discrepancy of fixed plate and locking plate relatively speaking, if square section of thick bamboo, still need to aim at the position with fixed plate or locking plate and just can lock and unblank, so very inconvenient consumes cyclist's time, and circular cylinder is simple high-efficient, has saved the unnecessary time for the cyclist.

In conclusion, the invention has the following beneficial effects:

1. the thief wants to steal the car and need open two locks of lock and fixed lock, and the key of two locks still inequality moreover, this very big increase the thief's of stealing the car degree of difficulty of stealing the car, guaranteed anti-theft device's theftproof effect.

2. When the electric motor car is not locked, the spring is taut in a fixed cylinder with the check lock lever to restricted the removal of check lock lever, led to the fact the vibration to lead to the check lock lever to deviate from the phenomenon of inserting in the rim when having avoided the cyclist to ride by bike, guaranteed the security when cyclist rides.
