Description
Technical field
The utility model belongs to automotive field, relates to a kind of auxiliary component of vehicle, is specifically related to a kind of passenger-car chassis protection prior-warning device.
Background technology
Along with socioeconomic fast development, people's living standard improves gradually, and automobile especially family-sized car recoverable amount continues to rise.The recoverable amount of car continues to rise and has caused the scarcity of city parking resource, and the phenomenon of parking difficulty is particularly serious in flourishing city.Because the construction of parking factory lags behind, and existing parking stall quantity is limited, city traffic management department has to offer in the road some interim parking stalls on both sides of the road, even the temporary term stop position is located at the doorway in some shops on the road step.
For first kind of situation, stop on both sides of the road in the road.Vehicle should be as much as possible near the roadside, and often car front bumper or rear bumper can be crossed road step as shown in figures 1 and 3, are not knowing under the situation of shoulder height, and the road step can come in contact with the bumper/spoiler of vehicle and cause damage.
For second kind of situation, the step of opening road stops.In opening the process of topping bar, because every chassis has own angle of attach and pass through the angle, to the difference of the control of the speed of a motor vehicle, what step and chassis might take place contacted " the dragging the end " that just is commonly called as when the driver topped bar in addition.To open when getting out of a predicament or an embarrassing situation situation as the same when car.
Owing to drag this situation of the end to have uncertainty, therefore be easy to cause damage to the part that is positioned at chassis portion, as: the fragmentation of ternary catalyzing unit shell, engine sump tank crackle, gear box casing crackle or suspension distortion etc., the generation of these problems will bring very fatal damage to vehicle.
Because the existence of above situation, can be through bring unnecessary trouble and economic loss to the car owner, invisible distortion takes place (this distortion is nonvolatil often and more serious meeting is the skeleton of vehicle, can not repair), the distortion dislocation at the mutual seat of suspension, or component materials is subjected to serious impact and is subjected to internal injury, causes material internal invisible internal injury again, brings serious threat to travel safety.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, a kind of passenger-car chassis protection prior-warning device is provided, and assists when this device stops to car early warning is provided, to avoid the injury of passenger-car chassis.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:

Each label is represented respectively among the figure: 1, first radar, 2, second radar, 3, the 3rd radar, 4, first warning light, 5, second warning light, 6, the 3rd warning light, 7, A/D converter, 8, buzzer phone, 9, micro controller system, 10, early warning panel.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
The specific embodiment
As shown in Figure 1, present embodiment provides a kind of passenger-car chassis protection prior-warning device, be installed in the car front bumper first radar 1, be installed in second radar 2 of chassis and be installed in the 3rd radar 3 of vehicle body rear bumper; Be installed in the vehicle body front bumper first warning light 4, be installed in second warning light 5 of chassis and be installed in the 3rd warning light 6 of vehicle body rear bumper; First radar 1, second radar 2 and the 3rd radar 3 link to each other by the input end of A/D converter 7 with micro controller system 9 respectively, and the mouth of micro controller system 9 connects first warning light 4, second warning light 5, the 3rd warning light 6 and buzzer phone 8 respectively.
As shown in Figures 2 and 3, in the present embodiment, first radar 1, second radar 2 and the 3rd radar 3 all adopt laser radar.Radar apart from detectability, dark bite, dust smogout the time performance and overall target such as temperature stability all better.Therefore, having the laser radar of good detectability and suitable all weather operation, is the optimal selection of the vehicle-mounted ranging system that tests the speed.The effect of above-mentioned three radars provides relative velocity and the distance of preceding rear bumper, chassis system and obstacle, judges whether to exist the foundation that contacts with obstacle as vehicle.
In the present embodiment, micro controller system 9 adopts MSP430 type micro controller system, this MSP430 type micro controller system is the super low power consuming single chip processor of 16 reduced instruction structures (RISC) of American TI Company production, its topmost characteristics are super low-power consumption and working stability: it can be operated between the 1.8V-3.6V, power consumption can be controlled in about 200 μ A during normal operation, can realize 2 μ A during low-power consumption mode, or even the super low-power consumption of 0.1 μ A.It mainly is made up of UART in 12 A/D converter, timer, the sheet, house dog, sheet internal oscillator and a large amount of I/O port and high-capacity on-chip memory etc.
Be illustrated in figure 4 as the early warning panel 10 that is installed in the operator's compartment, at early warning panel 10 first warning light 4, second warning light 5, the 3rd warning light 6 and buzzer phone 8 are installed, as long as detecting passenger-car chassis, first radar 1, second radar 2 and the 3rd radar 3 have the possibility that contacts with obstacle, MSP430 type micro controller system will be controlled buzzer phone 8 and sound a buzzer, and the warning light corresponding with it also can glimmer.
When passenger-car chassis protection prior-warning device uses; at first whole device is led to and power on; as shown in Figure 2; first radar 1 vertically sends signal earthward; when first radar 1 has detected obstacle; can transmit electromagnetic signal to A/D converter 7; A/D converter 7 is converted to electromagnetic signal digital signal input MSP430 type micro controller system again; MSP430 type micro controller system analytic signal; when signal reaches danger signal; the warning light 4 that control is corresponding with first radar 1 and buzzer phone 8 are worked, and play forewarning function, and chaufeur is seen that the warning light of early warning panel will stop and taken measures.
As shown in Figure 2, second radar, 2 levels send signal when second radar 2 has detected obstacle to the tailstock, can transmit electromagnetic signal to A/D converter 7, A/D converter 7 is converted to electromagnetic signal digital signal input MSP430 type micro controller system again, MSP430 type micro controller system analytic signal, when signal reached danger signal, the warning light 5 that control is corresponding with second radar 2 and buzzer phone 8 were worked, play forewarning function, chaufeur sees that the warning light of early warning panel will stop and take measures.
As shown in Figure 3, the 3rd radar 3 working processs are consistent with first radar 1 and second radar 2.
Above-described embodiment has been made detailed description to the utility model; the utility model is not limited to above-described embodiment; the all interpolations of doing on the technique scheme basis of those skilled in the art or correction or equivalents all should belong to protection domain of the present utility model.
