Description

Vehicle mechanical hand brake non-pulling alarm system

Technical Field

The utility model relates to a vehicle safety technical field specifically is a vehicle machinery manual brake does not pull up alarm system.

Background

Along with the improvement of the technology, the mechanical hand brake on the vehicle is gradually replaced by the electronic hand brake, so that the manual brake is more intelligent and automatic, and the manual brake can be automatically pulled up when the vehicle is parked. Still there are many trucks and passenger cars in the market still to continue the mode of using mechanical hand brake, because accident such as rear-end collision that do not draw the hand brake to cause takes place occasionally when parkking, therefore can remind also very profitable under the taut hand brake condition of vehicle parking.

The patent application number is 201220366155.3's a manual brake does not draw alarm device, including microprocessor, infrared probe, manual brake switch and warning circuit, infrared probe is towards driver's seat top, and its signal output termination is microprocessor's input port, manual brake switch one end bonding, another termination microprocessor's input port and be provided with the pull-up resistance, warning circuit's control signal input termination microprocessor's output port. This file utilizes infrared probe monitoring driver whether to leave the seat, utilizes the manual brake switch to judge simultaneously whether the manual brake is pulled up, if the driver does not pull up the manual brake when leaving the seat, then microprocessor output control signal makes the relay action, and buzzer sends alarm signal reminds the driver to pull up the manual brake to the emergence of traffic accident has effectively been prevented. However, the power supply of the device for alarming when the hand brake is not pulled is inconvenient, a power supply circuit in the vehicle is adopted for supplying power, and the circuit and the hand brake part need to be disassembled to achieve the purposes of power taking and signal input.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a vehicle machinery manual brake does not pull up alarm system to solve the problem of proposing among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a vehicle mechanical hand brake non-pull-up alarm system comprising: the device comprises a controller, a first sensor, a second sensor, a power supply and a loudspeaker, wherein the power supply is a storage battery and is connected with a cigarette lighter plug; the power supply is connected with the controller; an input of first sensor and second sensor all is connected with the output port of controller, and the input of first sensor still is connected with the output port of second sensor, first sensor is used for responding to the mechanical hand position of stopping, and the second sensor is used for responding to the driving seat and goes up the human body, the two inputs of loudspeaker are connected with controller and second sensor respectively.

As a further aspect of the present invention: the controller employs a DVB100 series control module.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, an alarm system for a mechanical hand brake of a vehicle that is not pulled up includes: the automobile ignition system comprises a controller CPU, a first sensor H1, a second sensor H2, a power supply C and a horn S, wherein the power supply C is a storage battery and is connected with a cigarette lighter plug, the cigarette lighter plug is connected with an automobile cigarette lighter base and can supply power to the power supply C, and the power supply C supplies standby power after the automobile is shut down; the power supply C is connected with a controller CPU, the controller CPU adopts a DVB100 series control module as a main control unit, can automatically set the upper and lower voltage limits, has two relay output functions inside, and is pulled in when the measured voltage is lower than a preset value; an input end of the first sensor H1 and the second sensor H2 is connected with an output port of a controller CPU, an input end of the first sensor H1 is connected with an output port of the second sensor H2, wherein the first sensor H1 is a photoelectric sensor used for sensing the position of the mechanical hand brake (the photoelectric sensor senses the change of an optical signal in the change process of the position of the hand brake and judges whether the hand brake acts), the second sensor H2 is a sensor used for sensing a human body on a driving seat and can be a gravity sensor or an infrared sensor, and two input ends of the horn S are connected with the controller and the second sensor H2 respectively.

The utility model discloses a theory of operation is: after the vehicle is flamed out, the power supply voltage is instantly reduced when a driver gets off the vehicle, the power supply C supplies power, a relay inside a controller CPU is activated, a first sensor H1 is powered on and senses the position of a hand brake, if the hand brake is not pulled up, the first sensor H1 outputs high level, a horn S is powered on, and an alarm sound is sounded;

at the vehicle idle speed, when the driver got off the bus, cigar lighter voltage was greater than the inside settlement voltage of controller CPU this moment, and the relay can't be activated, and first sensor H1 is not electrified, and second sensor H2 judges whether the driver is on the seat this moment, does not export the high level on the seat and gives first sensor H1, and first sensor H1 judges whether the manual brake is pulled up, if do not pull up, exports the high level, and loudspeaker alarm sounds.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
