Abstract
The utility model discloses a non-pull alarm device for a hand brake of a motor vehicle. The non-pull alarm device comprises a detection unit and an alarm (4), wherein the detection unit comprises an ignition switch (1), a vehicle door switch (2) and a hand brake switch (3) which are connected in series in sequence; the alarm (4) is connected in series with the detection unit, and forms a closed loop together with the detection unit; the vehicle door switch (2) is controlled to be switched on/off through a vehicle door sensor; and the hand brake switch (3) is controlled to be switched on/off through a hand brake sensor. According to the non-pull alarm device for the hand brake of the motor vehicle with the structure, the ignition switch is switched off at an OFF gear, and the vehicle door switch is switched off when locking of a vehicle door is detected through the vehicle door sensor; and when non-pull of the hand brake is detected by using the hand brake sensor, the hand brake switch is switched off, at the time a circuit is switched on, and the alarm makes an alarm for prompting a driver that the hand brake is not pulled, so that the risk of slippage of the vehicle is avoided.
Description
Technical field
The utility model relates to a kind of warning device, especially relates to a kind of motor vehicle hand brake and does not draw warning device.
Background technology
Existing vehicle does not possess when parking brake draws can send the function of warning, in driver's parking, when getting off, if cause because getting off hastily and forget the pull-up parking brake, thereby vehicle just might cause to slide and cause potential safety hazard, bring loss not only for self personal safety and property, also can bring the loss of the person and property to others.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of motor vehicle hand brake not draw warning device for problems of the prior art, its objective is after the driver is stopped the lock car, if parking brake does not draw, can report to the police always, remind the driver to strain parking brake, avoid vehicle sliding to cause accident.
The technical solution of the utility model is that this kind motor vehicle hand brake does not draw warning device to comprise detecting unit and annunciator, described detecting unit comprises ignition lock, door contact interrupter and the parking brake switch of series connection successively, described annunciator is connected with detecting unit, and forms C/LOOP with detecting unit.
Described door contact interrupter is controlled the switching of door contact interrupter by the car door sensor.
Described parking brake switch is controlled the switching of parking brake switch by the parking brake sensor.
This kind motor vehicle hand brake with said structure does not draw warning device, and when ignition lock is positioned at the OFF shelves, ignition lock is closed, locks when the car door sensor detects car door, and door contact interrupter is closed; Do not draw when the parking brake sensor detects parking brake, the parking brake switch is closed, and this moment, circuit was connected, alarm equipment alarm, and prompting driver parking brake does not draw, thus the risk of having avoided vehicle to slide.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1: ignition lock; 2: door contact interrupter; 3: the parking brake switch; 4: annunciator.
The specific embodiment
By structure shown in Figure 1 as can be known, this kind motor vehicle hand brake does not draw warning device to comprise detecting unit and annunciator 4, described detecting unit comprises ignition lock 1, door contact interrupter 2 and the parking brake switch 3 of series connection successively, described annunciator 4 is connected with detecting unit, and forms C/LOOP with detecting unit.
Door contact interrupter 2 is controlled the switching of door contact interrupter 2 by the car door sensor, parking brake switch 3 is controlled the switching of parking brake switch 3 by the parking brake sensor.
Above-mentioned motor vehicle hand brake does not draw the control method method of warning device to be:
1) when ignition lock 1 is positioned at the OFF shelves, ignition lock 1 closure;
2) when detecting car door, locks the car door sensor door contact interrupter 2 closures;
3) when detecting parking brake, do not draw the parking brake sensor parking brake switch 3 closures;
4) this moment, circuit was connected, and annunciator 4 is reported to the police, and prompting driver parking brake does not draw.
This kind motor vehicle hand brake does not draw warning device to work as ignition lock to be positioned at the OFF shelves, and ignition lock is closed, locks when the car door sensor detects car door, and door contact interrupter is closed; Do not draw when the parking brake sensor detects parking brake, the parking brake switch is closed, and this moment, circuit was connected, alarm equipment alarm, and prompting driver parking brake does not draw, thus the risk of having avoided vehicle to slide.
