Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
Brake treadle mechanism of the present invention, as shown in Figure 1, 2, comprises brake-pedal support 1, and pedal arm 2 is rotatably connected on pedal support 1.Thread drawing mechanism is connected to controllable pedal arm 2 on pedal arm 2 and moves, to realize braking.Control system control braking motor, this thread drawing mechanism drives to pull bracing wire to drive pedal arm 2 to move down by braking motor; Pedal arm 2 belows are provided with limits the lower position switch 5 that it moves down distance, and top is provided with the upper limit position switch 4 that limits its distance that moves up, and upper limit position switch 4 and lower position switch 5 are all arranged in the control circuit of braking motor.In the time that pedal arm 2 triggers lower position switch 5, control circuit disconnects, and motor stops drag, and keeps current location, continues braking; When pedal arm 2 upwards rotates, while triggering upper limit position switch 4, control circuit disconnects, and motor stops rotating backward, and braking departs from completely.
In the present invention, as shown in Figure 3, thread drawing mechanism comprises steel wire bracing wire 9, and one end of steel wire bracing wire 9 is connected on pedal arm 2 by pedal contiguous block 10, and the other end is connected to braking motor.Pulley 12 is walked around in steel wire bracing wire 9 middle parts, then from the hole of locking wire piece 9, pass and be connected to braking motor, its middle pulley 12 and locking wire piece 9 play certain positioning and guiding effect, ensure the stability of bracing wire campaign.Pulley 12 supports by pulley bracket 8, pulley bracket 8 and locking wire piece 9 are all connected on main bearing 6 by fastener, connect into as a whole after, be connected on brake-pedal support 1 by main bearing 6, this structure is convenient to installing/dismounting maintenance, also more stable in structure.Wherein lower position switch 5 connects by connection bracket 11 supporting and locations that are located on main bearing 6.
By above technical scheme, first lower position switch 5 is used together with fixing screw assembles with connection bracket 11, re-using Assembly of pin is connected in pulley 12 on pulley bracket 8, use fixing screw that pulley bracket 8 is connected on main bearing 6, then use tightening screw that locking wire piece 7 is connected on main bearing 6, again lower position switch 5 is connected to main bearing 6 by connection bracket 11, main bearing 6 is connected on brake-pedal support 1, re-using fixing screw is fixed on pedal contiguous block 10 on pedal arm 2, again steel wire bracing wire 9 is connected on pedal contiguous block 10 by connecting pin 13, pulley 12 is walked around in steel wire bracing wire 9, by locking wire piece 7, steel wire bracing wire 9 is connected in to braking motor assembly by locking wire piece 7 other ends, assemble complete.
Control system in brake treadle mechanism of the present invention comprises speed sensor, radar and the controller according to speed sensor and the running of radar transmission of signal control braking motor.Speed sensor and radar are connected with the input end of controller 8, and the mouth of controller 8 is connected with the starting switch of braking motor.
In the present invention, radar preferably uses millimeter wave radar, and millimeter wave radar refers to be operated in the radar of millimeter wave band, and frequency of operation is generally selected within the scope of 30～300GHz.Millimeter wave radar volume is little, quality is light, and spatial resolution is high, and the ability of penetrating fog, cigarette, dust is strong, has the feature of round-the-clock round-the-clock.
Limit switch is to utilize the collision of manufacturing machine movable parts to make its contact action realize connection or disjunction control circuit, reaches certain control object.Conventionally, this class switch is used to position or the stroke of limit mechanical motion, make movable machinery by certain position or stroke automatically stop, counter motion, variable-speed motion or back and forth movement etc. automatically.In actual production, limit switch is arranged on to prearranged position, in the time that pedal arm clashes into limit switch, the contact action of limit switch, realizes the switching of circuit.Therefore, limit switch is a kind of according to the travel position of movable parts and the electrical equipment of commutation circuit, and its action principle and button are similar.
Brake treadle mechanism of the present invention is in the time of work, the element monitoring motoring conditions such as braking motor Negotiation speed sensor, millimeter wave radar, the signal of reception is delivered to entire car controller by speed sensor and millimeter wave radar, controller sends instruction the starting switch in control circuit is opened, braking motor running.
In the time that the too fast need of car speed slow down or have obstacle to brake above, braking motor forward rotation pulls steel wire bracing wire 9, steel wire bracing wire 9 pulls pedal arm 2 along locking wire piece 7, pulley 12, pedal contiguous block 10, pedal is rotated, realize braking, in the time that pedal arm 2 triggers lower position switch 5, control circuit disconnects, braking motor stops drag, and keeps current location, continues braking.When car speed slows to setting value, can give it the gun time, speed sensor receives transmission of signal to controller, control braking motor rotates backward, under original clutch pedal retrun spring 3 antagonistic forces, pedal arm 2 upwards rotates, in the time triggering upper limit position switch 4, braking motor stops rotating backward, and braking departs from.
Under special circumstances, can also select can manual intervention, directly steps on brake pedal and realizes car brakeing.As occurred that when autobrake brake fault can not rotate pedal time, human intervention midway, push down on the pedal, realizes manually braking.
Brake treadle mechanism of the present invention can drive thread drawing mechanism by control system control braking motor, realizes braking, does not need manual intervention, thereby makes people obtain larger degree of freedom, in the time of long distance travel, has reduced people's fatigue driving problem especially; Under special circumstances, can also select can manual intervention, directly steps on brake pedal and realizes car brakeing.This brake treadle mechanism, installation, maintenance, easy to use, can select manual control or automatically control according to actual conditions, and more safe and reliable, saving muscle power easy to use, reduces the fatigue of driving, and has good application prospect.
By reference to the accompanying drawings the present invention is exemplarily described above; but the present invention is not limited to aforesaid way; as long as adopt the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out or directly apply to other occasion, all drop in protection scope of the present invention.
