Description

Automobile reversing alarm

Technical Field

The utility model relates to an auto-parts, especially a car alarm of backing a car.

Background

In order to ensure the driving safety of the automobile, a reversing alarm is installed on the existing automobile; the existing automobile reversing alarm is only provided with an ultrasonic sensor at the tail part of an automobile, and when an obstacle exists at the tail part of the automobile, the alarm gives out alarm sound to remind a driver. However, a single ultrasonic sensor in the conventional automobile reversing alarm can only accurately detect the obstacle at the fan-shaped position of the tail of the automobile, the detection range is small, and if an object approaching the automobile from one side of the tail of the automobile exists, the ultrasonic sensor is difficult to sense; simultaneously, the vehicle only just can send the chimes of doom when being close to the object, and the alarm that sends the chimes of doom is inside on-vehicle mode generally, mainly is in order to remind the driver, consequently, the difficult vehicle or the people that warn external autonomous movement of car alarm of backing a car, and warning effect is relatively poor. Therefore, the existing automobile reversing alarm has the problems of smaller reversing induction range and poorer warning effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an alarm for automobile backing. The utility model discloses not only can improve the response scope of backing a car, still have the better advantage of warning effect.

The technical scheme of the utility model: the utility model provides an alarm of backing a car, includes the control mainboard, and electric connection has reverse gear signal transmission module, audio alert module, on-vehicle bee calling organ, warning light, rear of a vehicle ultrasonic ranging ware, rear of a vehicle left side ultrasonic ranging ware and rear of a vehicle right side ultrasonic ranging ware on the control mainboard.

In the automobile reversing alarm, the control main board is electrically connected with a camera, and the camera is electrically connected with a vehicle-mounted display.

In the automobile reversing alarm, the control main board is electrically connected with red, yellow and green LED lamps.

In the car reversing alarm, the control main board is electrically connected with a reversing brake module, and the reversing brake module is connected with a switch.

Compared with the prior art, the utility model has the advantages that the car backing induction range is greatly improved by arranging the car tail ultrasonic distance measuring device at the car tail, the car tail left side ultrasonic distance measuring device at the left side of the car tail and the car tail right side ultrasonic distance measuring device at the right side of the car tail; the reversing warning lamp can continuously emit reversing light when reversing, and the voice alarm module can continuously broadcast reversing warning outwards when the automobile reverses, so that an external autonomous moving vehicle or person is reminded, and the warning effect is enhanced; the vehicle-mounted buzzer can send out an alarm to remind a driver of avoiding the barrier when the vehicle tail ultrasonic distance meter, the vehicle tail left side ultrasonic distance meter or the vehicle tail right side ultrasonic distance meter detects the barrier. In addition, the utility model discloses well accuse mainboard can open the camera when the car backs a car, and the camera can transmit the scene behind the vehicle to on-vehicle display, makes things convenient for the driver to directly observe the vehicle rear condition, and can avoid the condition of error detection; the red, yellow and green LED lamps can display different colors according to the ranging result, and the barrier distance is displayed to a driver in terms of color, so that the driver can conveniently judge the reversing distance; when the distance between the vehicle and the obstacle is less than 0.5m, the control main board controls the reversing brake module to start, so that vehicle collision is avoided; the driver can manually close the backing brake module, so that the driver can freely back a car and drive in places where strays are easy to be detected by mistake, and the operation is flexible. Therefore, the utility model discloses not only can improve the induction range of backing a car, still have that the warning effect is better, the vehicle rear condition is surveyd more conveniently, the distance of backing a car is judged more conveniently and is operated more nimble advantage.

Drawings

Fig. 1 is a flow chart of the present invention.

The labels in the figures are: 1-a control mainboard, 2-a reverse gear signal transmission module, 3-a voice alarm module, 4-a vehicle-mounted buzzer, 5-a reverse warning lamp, 6-a vehicle tail ultrasonic range finder, 7-a vehicle tail left ultrasonic range finder, 8-a vehicle tail right ultrasonic range finder, 9-a camera, 10-a vehicle-mounted display, 11-a red-yellow-green three-color LED lamp, 12-a reverse brake module and 13-a switch.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The utility model provides an alarm of backing a car, constitutes as shown in figure 1, including control mainboard 1, electric connection has reverse gear signal transmission module 2, audio alert module 3, on-vehicle bee calling organ 4, warning light 5, rear of a vehicle ultrasonic ranging ware 6, rear of a vehicle left side ultrasonic ranging ware 7 and rear of a vehicle right side ultrasonic ranging ware 8 on control mainboard 1.

The control main board 1 is electrically connected with a camera 9, and the camera 9 is electrically connected with a vehicle-mounted display 10; the control main board 1 is electrically connected with a red, yellow and green three-color LED lamp 11; the control main board 1 is electrically connected with a backing brake module 12, and the backing brake module 12 is connected with a switch 13.

The working principle is as follows: after a driver puts into reverse gear, the reverse gear signal transmission module 2 transmits a signal to the control mainboard 1, and the control mainboard 1 controls the voice alarm module 3 to continuously broadcast reverse warning outwards and continuously controls the reverse warning lamp 5 to emit light; meanwhile, the vehicle tail ultrasonic distance measuring device 6, the vehicle tail left ultrasonic distance measuring device 7 and the vehicle tail right ultrasonic distance measuring device 8 work simultaneously to start detecting obstacles behind and on two sides of the vehicle tail, and when the obstacles are detected, the vehicle-mounted buzzer 4 alarms to remind a driver of the existence of the obstacles behind; the camera 9 at the position of the tail of the vehicle can transmit the condition of the tail of the vehicle to the vehicle-mounted display 10 in a video mode, so that a driver can conveniently observe the condition of the tail of the vehicle; when the obstacle is larger than 3m, the red-yellow-green three-color LED lamp 11 displays green lamps, when the obstacle is larger than 1m and smaller than 3m, the red-yellow-green three-color LED lamp 11 displays yellow lamps, and when the obstacle is smaller than 1m, the red-yellow-green three-color LED lamp 11 displays red lamps, the distance of the obstacle is displayed to a driver in color, and the driver can conveniently judge the distance of backing a car; when the distance between the vehicle and the obstacle is less than 0.5m, the control main board 1 controls the backing brake module 12 to start, so that vehicle collision is avoided; the driver can manually close the backing brake module 12 through the switch 13, so that the driver can freely drive in a backing mode in places where strays are easy to be detected by mistake, and the operation is flexible.
