Description

Technical Field

[0001] The present invention is designed in the field of automobiles, specifically a device and method for preventing automobiles from chain collisions Background Art

[0002] The number of cars in society is increasing every day, and the probability of car collision accidents is also increasing. It is very important to prevent or reduce the occurrence of car collision accidents from a technical perspective.

[0003] Existing automobile collision avoidance technologies mainly focus on ranging collision avoidance, such as radar laser ranging collision avoidance and visual shooting intelligent collision avoidance. However, these technologies still have limitations, such as weather factors.

[0004] The present invention avoids these two types of automobile anti-collision technologies and takes a unique approach. Its main function is to prevent automobile chain collision accidents. When a car collides, it means that the driver has an abnormality, such as fainting due to sudden illness, hallucinations, drowsiness, etc., or the driver deliberately drives the car to collide with people. No matter what the reason is, as long as a collision occurs in front of the car during driving, the invented device and method for preventing automobile chain collisions can replace the driver to stop the car at the fastest speed, thereby avoiding automobile chain collision accidents and reducing the damage caused by automobile collision accidents. Summary of the Invention

If it needs to be reset and the circuit is changed, it will not be described in the present invention; The relay has 1 contact, 2 contacts, 3 contacts, 4 contacts, and 4 wire contacts; When the relay contact 1 is energized, the internal coil is attracted to connect the contacts 3 and 4; The relay 3 contacts are connected to the power supply via wires; Contacts 3 and 4 of the relay are in a normally open state. Only when contact 1 is energized and the internal coil is attracted, contacts 3 and 4 will be connected, and contact 4 will be energized. The relay contacts 4 are normally voltage-free; The relay has a self-locking circuit, wherein the self-locking circuit is a circuit in which four contacts are connected to one contact via a wire; In the relay, contact 1 is energized by the electrical switch, and the internal coil of contact 1 is energized, connecting the circuit of contacts 3 and 4. Contact 3 is connected to the power supply through wires, and contact 4 is energized by connecting contact 3. The voltage of contact 4 is connected to the electric push-pull rod through wires, and contact 4 is connected to contact 1 through wires, so that contact 1 is continuously energized, thereby ensuring that the voltage of contacts 3 and 4 is continuously connected. This is a self-locking circuit; The electric push-pull rod is connected to the brake pedal via a brake line; When the bumper plate of the car touches a person or object during driving, the bumper plate physically moves backward, triggering the electrical switch, which turns on. The voltage of the power supply is connected to the relay through the wire from the electrical switch, and the relay is energized. The coil of the relay 1 contact starts to attract, so that the normally open circuit of the relay 3 and the relay 4 contacts is connected. The normally open circuit 3 of the relay is connected to the power supply through the wire, and the normally open contact 4 of the relay is connected to the electric push rod through the wire; The voltage of the power supply is connected to the relay contact 3 through the wire, the voltage of the power supply goes to the relay contact 3, and then to the relay contact 4, and then the voltage of the power supply goes to the electric push-pull rod through the wire. The electric push-pull rod is energized, and the push-pull rod of the electric push-pull rod is pulled back, driving the brake pedal to be pressed down through the connected brake line, forming a braking action.

[0006] When the contact coil of relay 1 is energized, relay point a and point b are connected, the power supply voltage is connected to point b through relay point a, relay point b is connected to the electric push rod through an electric wire, the electric push-pull rod is energized, the electric push-pull rod works, and the electric push-pull rod pulls back with a speed of 1 second and a pulling stroke of 100mm. There is no limit on this stroke speed, it is just for a better expression and can be adjusted according to actual conditions. The method is described here. The electric push-pull rod is connected to the car brake pedal through the brake line. When the electric push-pull rod is pulled, the electric push-pull rod pulls the brake pedal downward through the brake line, which is equivalent to replacing the driver's foot pressing the car brake pedal to brake, thereby achieving the purpose of preventing the car from a chain collision or reducing the loss of the car from a collision.

[0007] The relay point a is a 3-contact point, and the relay point b is a 4-contact point. If a car is traveling too fast and suddenly brakes, it may cause a safety hazard, such as rollover. Therefore, this invention provides a device and method for preventing a car from experiencing a chain collision. The device is suitable for use within a city speed limit of 60 km / h. If the car speed exceeds 60 km / h, the anti-collision function will be turned off. The beneficial effects of the present invention are as follows: A device and method for preventing a car from a chain collision. When a front collision occurs during driving, the car's bumper plate is physically moved backward under pressure. During the backward movement of the car's bumper plate, an electrical switch is triggered. The electrical switch is turned on to transmit voltage to a relay. The relay is energized and transmits voltage to an electric push rod. The electric push rod is energized and drives the brake pedal downward through the brake line. In response to the driver's foot pressing the brake pedal, the car is braked, thereby preventing the car from a chain collision accident or reducing the damage caused by the collision.

[0008] This invention can serve as the main fool-proof collision avoidance technology for future smart cars, and can also be a supplement to current radar and visual collision avoidance technologies. Future smart cars will need to superimpose multiple collision avoidance technologies to improve the driving safety performance of the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention will be further described below with reference to the accompanying drawings. Figure 1 It is a schematic diagram of the present invention Figure 2 This is the relay wiring diagram of the present invention DETAILED DESCRIPTION

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the picture: 01, car bumper; 02, electrical switch; 03, power supply; 04, wires; 05, relay; 06, electric push-pull rod; 07, brake cable; 08, brake pedal; 09, spring; like Figure 1 In the embodiment shown, the car bumper 01 is installed in the front of the car. The car bumper can be understood as a car bumper or can replace the bumper. Its first function is to contact the object to be collided with, and its second function is to trigger the electrical switch 02 on the back. The triggering of the electrical switch 02 turns on the electrical switch. Preferably, the car bumper 01 is made of rubber; Preferably, the car bumper is a rubber inflatable cushion, which can be inflated through an air nozzle; The optional shape of the car bumper is an elliptical rectangular U-shape; The car bumper is installed in front of the car and can be fixed by screws, welding, glue, or steel cables, without limitation. Next, there is a spring 09 behind the car bumper 01. The spring 09 is installed between the car bumper 01 and the car beam or car sheet metal. The function of the spring is to buffer and absorb energy. Next, install the electrical switch 02 behind the car bumper 01; Next, the voltage input end of the electrical switch 02 is connected to the power supply 03 via the wire 04, and the voltage output end of the electrical switch 02 is connected to the 1st contact of the relay 05 via the wire 04; like Figure 2 As shown, the relay 05 has contact 1, contact 2, contact 3, and contact 4, wherein contact 3 and contact 4 form a normally open circuit. When the coil of contact 1 is energized and energized, the circuits of contact 3 and contact 4 are connected. Contact 3 is connected to power source 03 via wire 04. Next, the 4 contacts of the relay 05 are connected to the electric push-pull rod 06 via the wire 04; The optional electric push-pull rod is energized and continuously pulled back. If a reset circuit is required, the present invention does not describe this because the main purpose of the present invention is to prevent a chain collision of vehicles. Next, the push-pull rod end of the electric push-pull rod 06 is connected to the brake pedal 08 via the brake line 07; The specific implementation method of the present invention is as follows: when the car bumper 01 collides with a person or other object, the car bumper 01 is physically moved backward under pressure or is under pressure from the back, causing the electrical switch 02 at the back to turn on. At this time, the voltage of the power supply 03 is transmitted through the wire 04 through the electrical switch 02 and then through the wire to the 1st contact of the relay 05. The 1st contact of the relay is energized by the coil, connecting the 3rd contact and the 4th contact circuit of the relay 05. Next, the voltage of the power supply 03 is connected to the 3rd contact of the relay 05 through the wire 04, and the voltage of the 3rd contact is transmitted to the 4th contact. The voltage of the 4th contact is transmitted to the electric push-pull rod 06 through the wire 04. The electric push-pull rod 06 is energized to start working. The starting work is the pushing of the electric push-pull rod 06. The pull rod is pulled backward, and the electric push-pull rod 06 transmits the force to the brake pedal 08 through the brake line 07, and the linked brake pedal is pulled down, which is equivalent to the driver stepping on the brake pedal 08 to brake the car. Specifically, the electric push-pull rod 06 is pulled backward. Because the push-pull rod is connected to the brake pedal 08 with the brake line 07, when the push-pull rod of the electric push-pull rod 06 moves backward and drives the brake line 07 to move backward, it will also press the brake pedal 08 down, which is equivalent to stepping on the brake pedal 08 to brake the car instead of the driver, so as to achieve the purpose of automatically braking to prevent the car from colliding, so as to achieve the purpose of preventing the car from a chain collision, so as to achieve the purpose of reducing the degree of damage and loss caused by a collision. like Figure 2 As shown, the relay 05 has a self-locking circuit. The function of the self-locking circuit is to ensure that contact 1 is not disconnected when the car collides. As long as contact 1 is not disconnected, the circuits of contacts 3 and 4 are continuously connected. Contact 4 remains energized to ensure that the electric push-pull rod 06 continues to work. The continuous operation of the electric push-pull rod 06 means that the force pulling the push-pull rod backward has not disappeared. The force pulling the push-pull rod backward has not disappeared, and it is transmitted to the brake pedal 08 through the brake line 07. The pulling force will not disappear, thereby ensuring that the brake pedal 08 always maintains the braking state, and ultimately ensuring that the car maintains the braking state after a collision. Otherwise, when the car collides and knocks people away, because the car bumper plate 01 does not touch the collided object after knocking people away, the pressure disappears, and then the electrical switch 02 behind the car automatically recovers, and the electrical switch 02 returns to its original state, which means that the output end of the electrical switch 02 is de-energized, and then the 1st contact of the relay 05 is de-energized, and the 3rd and 4th contact circuits of the relay 05 are also de-energized. The 4th contact of the relay 05 is de-energized, resulting in the electric push-pull rod being unable to pull the brake pedal 08, which may cause a chain collision accident of the car. The car bumper plate 01 is pressed and moves backward, which in turn turns on the electrical switch 02. The electrical switch 02 transmits the voltage of the power supply 03 to contact 1 of the relay 05. The coil of contact 1 is energized to connect the circuit of contacts 3 and 4 of the relay 05. In order to ensure that contact 1 of the relay 05 is continuously energized, thereby ensuring that the circuit of contacts 3 and 4 is not disconnected, we use wire 04 to connect contact 1 to contact 4. In this way, when the car does not collide, the car is in a normal state. When the car collides, for example, a person is knocked away, whether the object of the collision touches the car bumper plate 01, in order to prevent a secondary chain collision accident, the invention will keep the car in a braking state, because at this time even if the electrical switch 02 is powered off, but because the voltage of contact 04 returns to contact 1, contact 1 continues to connect the circuit of contacts 3 and 4, thus forming a cycle.

[0011] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
