Problems solved by technology

One of the disadvantages of this technology is that the practicability of the mechanical device for starting the car brake is not strong
[0003] Chinese patent application 201001130092.4 "A Device for Automatically Correcting Misstepped Accelerators into Brakes with the Coordination of Electric Appliances and Machinery" discloses a device including a sensor, a signal analyzer and a brake activation mechanism. There are many electronic devices, and the reliability is reduced; the second disadvantage is that in the brake activation mechanism, the circular motion of the solenoid valve is changed into the reciprocating motion of the brake cable, and the straight rack is used to change the motion mode, because the straight tooth must be kept The reciprocating motion of the bar positioning requires a frame to fix the relative position of the solenoid valve and the straight rack. This frame is bulky and difficult to find a suitable location for installation. Moreover, the structure is complex, the cost is high, the reliability is not good, and the practicability is not strong. , and the solenoid valve in the brake activation mechanism maintains the locked-rotor state of the brake, which is easy to damage the solenoid valve

Embodiment 1

[0046] Embodiment 1. Semi-automatic error correction braking system for externally rotating fixed angle solenoid valve

[0047] Such as figure 1 , 2 , 3, including the sensor 9---sensing signal analyzer 10---control signal power amplifier 11---power controller 12 connected successively in order to transmit electrical signals, and in order to convert electrical energy into mechanical energy, use The power controller 12 is connected with an outer jacket rotating body type fixed angle solenoid valve 14 and the power controller 12 is connected with a DC power supply 15 that drives the outer jacket rotating body type fixed angle angle electromagnetic valve 14 .

[0048] The following is a description of each part:

[0049] The sensor 9 is one of a pressure sensor, a speed sensor or an acceleration sensor or a combination thereof; the sensor 9 transmits a sensing signal to a sensing signal analyzer 10 . That is to say, sensor 9 is to use a certain kind in pressure sensor, speed s...

Embodiment 2

[0059] Embodiment 2. Semi-automatic error correction braking system for externally rotating fixed angle solenoid valve

[0060] As in embodiment 1, the fixed-angle solenoid valve 14 of the overcoat rotating body is optimized as follows:

[0061] After the two coils 6 wound to the same direction are penetrated respectively from the two ends of a straight iron core 7, a coil larger than the cross section of the straight iron core 7 is respectively fixed at the two ends of the straight iron core 7. The gear coil piece identical with straight iron core 7 materials makes this straight iron core 7 become " I " font. Also carry out the same process to another straight iron core 7, also become " I " font straight iron core 7.

[0062] The outer surface of the jacket rotating body 2 is fixedly connected with one end of a stay cord 8 , and the other end of the stay cord 8 passes through the hole of the housing 3 . When the overcoat rotating body 2 is rotated at an angle of 80 degrees,...

Abstract

The invention relates to a semi-automatic error correction braking system with an outward rotating solenoid valve having fixed rotation angle, in particular to the semi-automatic error correction braking system which can change an accidental step on an accelerator into an error correction braking. The semi-automatic error correction braking system comprises a sensor, sensor signal analyzer, a control signal amplifier and a power supply controller, which are sequentially connected with one another. The power supply controller is connected with the outer sleeved rotator type solenoid valve having fixed rotation angle and a direct current power supply of the outer sleeved rotator type solenoid valve having fixed rotation angle. The semi-automatic error correction braking system with the outward rotating solenoid valve having fixed rotation angle has the advantages that response speed from detecting the accidental step on the accelerator to correcting the accidental step into braking is fast, the solenoid valve which drives a brake is accurate in operation, full-automatic error correction braking can be achieved with no rotator locking, and a braking state can be maintained for a long time without power consumption until a driver manually restores a state before the system starts.

Description

technical field [0001] The invention belongs to the technical field of brakes for automobiles, in particular, it can transform the human operation of accidentally stepping on the accelerator into a semi-automatic automobile brake system capable of automatic braking and manual reset of an error correction braking system. Background technique [0002] Chinese patent 200510022077.X "Accelerator System Device with Annunciator" provides a device that can judge whether the accelerator action is correct or wrong before determining whether to remedy and brake, so that the accelerator can be used for both braking and acceleration. Motor vehicle accelerator pedal system. It is characterized in that an annunciator is arranged on any one of the accelerator pedal, the linkage device and the vehicle body device. The annunciator is connected with the electric valve that can cut off the engine oil circuit and the electric valve on the wheel brake. This technology proposes to use electroni...
