The utility model relates to a rationally, can realize respectively that the rear wheel rotates the warning, cuts off functions such as hall line warning, electricity key closing warning, can be supporting the use on the electric bicycle of various different grade types, can effectively improve its safety theftproof nature.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle burglar alarm, belongs to the auxiliary device technical field of Electrical Bicycle.
Background technology
Along with the raising day by day of people's living standard, Electrical Bicycle is more and more accepted by the customer as new transportation vehicles, but because the price of Electrical Bicycle is still high, the focus that its safe antitheft problem has also just become the car owner to be concerned about the most.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can realize the Electrical Bicycle burglar alarm of anti-theft alarm under the various service conditions of Electrical Bicycle.
The utility model is the Electrical Bicycle burglar alarm, mainly by housing, places the warning circuit plate in the housing, place the outer power interface that links to each other with the warning circuit plate of housing, the Hall element signal input, Electrical key signal input, formations such as warning rattler; Described warning circuit plate is provided with NAND gate A, Exclusive-OR gate (XOR gate) B, and univibrator C is with door D; Described Hall element signal input reaches through univibrator C with Exclusive-OR gate (XOR gate) B by NAND gate A respectively and links to each other with the warning rattler with door D; Described Electrical key signal input passes through univibrator C and links to each other with door D and warning rattler respectively.
The utility model is reasonable in design, can be separately implemented at the Electrical key start signal not the trailing wheel under the input condition rotate and report to the police, do not cut off under the input condition that the Hall report from a liner is alert, validated user is closed functions such as warning by the open and close Electrical key in the Electrical key start signal, when the thief steals car, annunciator just can send chimes of doom and deter the thief and notify the car owner, and this burglar alarm can also be distinguished small misoperation simultaneously.The utility model can supporting use on various dissimilar Electrical Bicycles, can effectively improve its safe antitheft.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model;
Fig. 2 is the control principle scheme drawing of warning circuit plate described in the utility model.
The specific embodiment
The utility model places the warning circuit plate 1 in the housing 2 mainly by housing 2, places the housing 2 outer power interfaces 5 that link to each other with warning circuit plate 1, Hall element signal input 3, Electrical key signal input 6, warning rattler 4 formations such as grade.Warning circuit plate 1 is provided with NAND gate A, Exclusive-OR gate (XOR gate) B, univibrator C, with door D etc.; Hall element signal input 3 reaches through univibrator C with Exclusive-OR gate (XOR gate) B by NAND gate A respectively and links to each other with warning rattler 4 with door D; Electrical key signal input 6 passes through univibrator C and links to each other with door D and warning rattler 4 respectively.Hall element signal input 3 and Electrical key casually input port 6 respectively with Electrical Bicycle on Hall element be connected with Electrical key.
Power interface 5 external working powers, for the NAND gate A on the warning circuit plate 1, Exclusive-OR gate (XOR gate) B, univibrator C, with power supplies such as a door D, alarm generator 4.
1. when the Electrical key start signal is not imported, be high level, this signal to door D; If trailing wheel rotates, by Hall element signal output one turn signal (high level), this signal is input to Exclusive-OR gate (XOR gate) B, three road Hall element signals are after NAND gate A carries out NAND operation simultaneously, export another high level to Exclusive-OR gate (XOR gate) B, this two paths of signals is output one low level after differentiation, computing, triggering univibrator C output high level arrives and door D, this road signal and Electrical key signal are after carrying out AND operation with door D, the output high level drives alarm generator 4 and sends chimes of doom.
2. under the situation that the Electrical key start signal is not imported, cut off the Hall element signal, three road Hall element signals are pulled to high potential, after NAND gate A carries out NAND operation, export a low level to Exclusive-OR gate (XOR gate) B, three road Hall element signal wire (SW)s are cut off, another road signal that the Hall element signal is delivered to Exclusive-OR gate (XOR gate) B also is low level, this two paths of signals is exported a low level after Exclusive-OR gate (XOR gate) B carries out nonequivalence operation, trigger univibrator C output high level to door D, this road signal and Electrical key signal are after carrying out AND operation with door D, and the output high level drives alarm generator 4 and sends chimes of doom.
3. under the situation of Electrical key start signal input, the road signal that is input to door D is a low level, and at this time, no matter univibrator C is high level or low level, with the equal output low level of door D, at this moment, alarm generator 4 does not send chimes of doom.
4. when alarm generator 4 sent chimes of doom, validated user can reset univibrator C, thereby close chimes of doom by opening Electrical key or open and close Electrical key once.
Claims (1)
