a) Field of the Invention
The present invention relates to a multi-functional burglar-proof lockset assembly structure, and more particularly to a multi-functional burglar-proof lockset assembly structure which is provided with a burglar-proof alarm circuit that can precisely detect bands in large range.
b) Description of the Prior Art
Many people are now configuring an electronic burglar-proof device or a mechanical burglar-proof lockset for their cars to secure them without being stolen. However, no matter using what kind of mechanical lockset that is precise, hard to unlock, robust, and hard to damage, or what kind of electronic burglar-proof device that senses precisely and is provided with multiple functions, it can only delay a carnapper to successfully steal the car, due to a brilliant stealing technique of the carnapper. Therefore, a complete burglar-proof effect cannot be truly achieved. As a matter of fact, it is not difficult to unlock or damage the lockset, as long as one has sufficient time and well-prepared equipment. Accordingly, an ideal and effective burglar-proof device should be both provided with the features of a mechanical lockset that is robust and hard to damage, and of a burglar-proof alert device that is precise and sensitive. Furthermore, when a thief is stealing the car, many different frequencies will be formed due to many different actions; therefore, when the electronic burglar-proof device is detecting a change of ambient condition, many sensors for detecting different bands should be used to detect different frequencies, and trigger the burglar-proof device. When an ordinary burglar-proof alarm is triggered, most of the time only alarm sound is sent out on the car. Therefore, unless a car owner happens to be near his or her car, the owner will not be able to be aware of that burglar-proof alarm signal to react in time. Accordingly, the alarm sound of conventional burglar-proof alarm can only deter a thief, and is not able to alert the car owner to take an action in time.
The primary object of present invention is to provide a multi-functional burglar-proof lockset assembly structure, which is provided with a burglar-proof alarm circuit that can precisely detect bands in large range, and an automobile burglar-proof alarm lock that can be fitted with a personal alert device to inform a car owner in time, thereby being both equipped with a long-range burglar-proof alert function and a two-way remote-control function.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

The barometric detection unit C3 which operates by a signal of change of atmospheric pressure includes an atmospheric pressure signal amplification and sensitivity adjusting loop C31 and a comparison loop C32, wherein a pressure detection loop of the atmospheric pressure amplification and sensitivity adjusting loop C31 can detect a momentary change of air pressure in the car, and transform a monitored message into an electronic signal which is processed by the comparison loop C32 and is then transmitted to the central processing unit C9 for discrimination, thereby effectively detecting the change of atmospheric pressure in the car.
The ultrasonic detection unit C4 which operates by a signal of object movement includes an ultrasonic emission part C41 that sends out an ultrasonic signal to a space in the car, and an ultrasonic receiving part C42 for receiving the signal which is analyzed and processed and is then transmitted to the central processing unit C9 for discrimination. The ultrasonic emission part C41 is provided with a high-frequency oscillation loop C411, a signal pushing loop C412, and an ultrasonic emitter C413; whereas the ultrasonic receiving part C42 is provided with an amplification loop C421 which can amplify a reflection wave signal, a detection loop C422, a filter loop C423, a sensitivity adjusting loop C424, a low-frequency amplification loop C425, a low-pass amplification loop C426, a high-pass amplification loop C427, and a signal comparison loop C428.
The ultrasonic signal prevention and detection unit C5 which operates when the signal disappears is provided with an amplification loop C51, a detection loop C52, and a comparator loop C53, to output a signal level to the central processing unit C9 for discrimination, such that when the signal disappears, the signal can be outputted to the central processing unit C9 for discrimination.
The glass-fracture detection unit C6 which operates when a glass fractures is provided with a sensitivity adjusting loop C61, an amplification loop C62, a detection loop C63, and a comparator loop C64, such that when a car window fractures, a signal will be immediately outputted to the central processing unit C9 for discrimination; or when a thief uses a strong signal to interrupt, the glass-fracture detection unit C6 will also output the signal to the central processing unit C9 for discrimination.
The radio wave receiving unit C7 which operates by receiving a radio wave signal of the personal alert device D is provided with a receiving antenna loop C71, a high-frequency amplification loop C72, a super-regenerative receiving loop C73, and a low-frequency signal amplification loop C74, to receive the radio wave signal sent out by the personal alert device D. The radio wave signal is processed, and is then outputted to the central processing unit C9 for program decoding, so as to facilitate that when the car owner enters into the car, he or she can remotely configure a delay to alarm first.
The vibration detection unit C8 which operates when the vibration sensor C2 detects a vibration situation is provided with a low-pass filter loop C81, a sensitivity adjusting loop C82, a low-frequency signal amplification loop C83, a positive and negative signal level discrimination and comparison loop C84, and an output loop C85, such that when the car vibrates abnormally, a signal can be outputted to the central processing unit C9 for discrimination.
By the detection end C1 and the vibration sensor C2, many kinds of possible situation which occur when the car is stolen, can be detected, thereby improving an automobile burglar-proof effect by the burglar-proof lockset A.
The personal alert device D is provided with a loop of an LCD display screen D1, which is controlled by a central processing unit D2 to display the burglar-proof alert signal on the LCD display screen D1. The personal alert device D is also provided with an energy-saving control program interface D3 which can shutdown the LCD display screen D1 to save energy consumption.
The personal alert device D is provided with a radio wave emission unit D4 which can send out the radio wave signal to the burglar-proof alarm circuit C to match codes of the burglar-proof alarm circuit C and a program of the personal alert device D, or to remotely activate the burglar-proof alarm circuit C to enter into a procedure of delaying alarm. In addition, the personal alert device D is provided with a radio wave receiving unit D5, to receive and process the radio wave signal, and to output the processed signal to the central processing unit D2 for discrimination.
When the lockset B is locked, the burglar-proof alarm circuit C is activated, and a power-on signal is transmitted by the radio wave emission unit C10. After the radio wave receiving unit D5 of the personal alert device D receives the power-on code, the power-on reaction will be active and the personal alert device D will be in the power-on state. In addition, after the burglar-proof alarm circuit C further executes a delay procedure, a burglar-proof alerting state will be active. If the detection end C1 and the vibration sensor C2 of the burglar-proof alarm circuit C are triggered, timed alarm flashing and sounding will be immediately executed. In a mean time, the radio wave emission unit C10 will transmit the signal to the radio wave receiving unit D5 of the personal alert device D, and conditions of the car will be displayed on the LCD display screen D1, enabling the detection end C1 and the vibration sensor C2 to achieve a burglar-proof function with multiple alerts and a function of ultrasonic signal prevention, as well as to allow a user to take a necessary approach in time, through the burglar-proof alarm circuit C.
