Description
Technical Field
The utility model relates to an automobile field, concretely relates to car weighs down cliff protection system and car.
Background
With the high-speed development of electric vehicles, people have higher and higher requirements on the safety of the vehicles. In the driving process of the vehicle, the vehicle falls from a high place due to misjudgment of a driver on the road condition, and at the moment, the battery explosion possibly caused by the fact that the traditional electric vehicle seriously impacts the ground after falling can also threaten the safety of personnel in the vehicle.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the danger that the car that exists weighs down the cliff and brings among the prior art, provide a car weighs down cliff protection system and car through adopting tire pressure relief mode buffering impact.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
an automobile falling cliff protection system comprises a gravity acceleration sensor, a controller and a tire pressure relief module; the output end of the gravity acceleration sensor is connected with the input end of the controller, and the output end of the controller is connected with the control end of the tire valve through the tire pressure relief module; and the controller controls the tire pressure relief module to relieve the pressure of the tire according to the signal output by the gravity acceleration sensor.
Preferably, the automobile falling cliff protection system further comprises a tire pressure monitoring module connected with the input end of the controller.
Preferably, the automobile falling cliff protection system further comprises a vehicle speed sensor connected with the input end of the controller.
Preferably, the vehicle speed sensor is a vehicle body electronic stability regulation system ESC.
An automobile comprising the automobile fall protection system.
Compared with the prior art, the beneficial effects of the utility model are that: through combining together tire pressure monitoring module and gravity acceleration sensor, realized making the tire release after the car falls, reached the purpose of buffering impact, protected personnel in the car, reduced simultaneously that big battery takes place serious striking and causes the danger of explosion in the car, improved the security of car.
Description of the drawings:
fig. 1 is a system block diagram of an automobile falling-down protection system according to an exemplary embodiment 1 of the present invention.
Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter is limited to the following embodiments, and all the technologies realized based on the present invention are within the scope of the present invention.
Example 1
As shown in fig. 1, the present embodiment provides an automobile cliff protection system, which includes a gravitational acceleration sensor, a controller, and a tire pressure relief module; the output end of the gravity acceleration sensor is connected with the input end of the controller, and the output end of the controller is connected with the control end of the tire valve through the tire pressure relief module; and the controller controls the tire pressure relief module to relieve the pressure of the tire according to the signal output by the gravity acceleration sensor.
In the embodiment, whether the automobile falls from a high place is judged through signals acquired by the gravity acceleration sensor; after the automobile is determined to fall from a high place according to the signal of the gravity acceleration sensor, the automobile falling cliff protection system controls the tire to release pressure so as to buffer the impact force, thereby protecting personnel in the automobile and simultaneously reducing the danger of explosion caused by serious impact of a large battery in the automobile. The tire pressure relief module can begin to relieve pressure after the automobile falls from a high place, the pressure relief speed and the like are determined according to the practical application condition, and the situation that the tire is not completely relieved when the automobile contacts the ground is ensured. The application of the gravity acceleration sensor to the automobile to identify the condition that the automobile falls from a high place is the conventional technical means; the embodiment combines together tire release module and gravity acceleration sensor, has realized making the tire release after the car falls, reaches the purpose of buffering the impact, has improved the security of car.
Further, the automobile falling cliff protection system further comprises a tire pressure monitoring module connected with the input end of the controller. After the automobile falls from a high place, if the pressure is not timely released after the automobile touches the ground, a good protection effect cannot be achieved, and the latest opportunity of pressure release is determined through the tire pressure monitoring module so as to improve the safety. After the automobile is determined to fall from a high place according to the signal of the gravity acceleration sensor, the automobile falling cliff protection system controls the pressure relief of the tire through the tire pressure monitoring module when the tire of the automobile contacts the ground so as to buffer the impact force, thereby protecting personnel in the automobile and simultaneously reducing the danger of explosion caused by serious impact of a large battery in the automobile.
Furthermore, the automobile falling cliff protection system also comprises a vehicle speed sensor connected with the input end of the controller. The vehicle speed sensor is used for identifying the vehicle speed of the vehicle, and the controller controls the tire pressure relief module to relieve the pressure of the tire according to the signal output by the tire pressure monitoring module after detecting that the gravity acceleration and the vehicle speed of the vehicle reach preset conditions, so that the impact force caused by falling is powerfully relieved. Whether the automobile falls from a high place or not is judged only through the gravity acceleration, the misjudgment condition exists, and at the moment, if the automobile is in a running state, the pressure relief of tires can cause the running of the automobile to be out of control, so that safety accidents can be caused. The embodiment detects the speed of a motor vehicle through speed sensor and combines the information judgement vehicle that gravity acceleration sensor gathered to be in unsettled state, improves the accuracy of judging that the car is in the eminence state of falling, avoids the accident that the erroneous judgement phenomenon brought. The existing vehicle body electronic stability adjusting system ESC of the vehicle is adopted to detect the vehicle speed and judge whether the vehicle is in a suspended state.
Example 2
This embodiment provides an automobile comprising the automobile fall protection system of embodiment 1. Through the automobile falling cliff protection system, the pressure of tires is relieved when the automobile falls to the ground, the purpose of buffering impact force is achieved, and the safety of the automobile is improved.
The above description is only for the purpose of illustrating the embodiments of the present invention, and not for the purpose of limiting the same. Various substitutions, modifications and improvements may be made by those skilled in the relevant art without departing from the spirit and scope of the invention.
