Abstract
The utility model discloses a foot pedal electromechanical switch special for an automobile speed slowing device, comprising a pedal and the braking controller of the automobile. The foot pedal electromechanical switch also comprises a casing, a micro switch, a drawing block, a drive rod and springs. The micro switch is arranged out of the casing and electrically connected with the braking controller of the automobile, and the drawing block is arranged on one end of the drive rod. The spring is ring-sheathed with the drive rod, and the drawing block is provided with shifts with different positions; the drawing block moves to the different positions along with the drive rod, and the shifts of the drawing block drive different micro switches. The casing of the foot pedal electromechanical switch is provided with two pairs of the micro switches electrically connected with the braking controller of the automobile. When the foot pedal is raised gradually, the drive rod moves towards right direction in a sliding bush under the action of the tension of compression springs; the drive rod drives the drawing block to move at the same time. The shifts of the drawing block move to the different positions along with the drive rod and respectively trigger the different micro switches. The braking controller of the automobile can be started for slowing up the speed of the automobile.
Description
Technical field
The utility model relates to the special-purpose foot-operated switch of a kind of automobile retarder, is the improvement technology of the special-purpose foot-operated electric mechanical switch of automobile retarder specifically.
Background technology
At present, people run into that there is obstacle the front or when stopping, the moving velocity of automobile slowly need be reduced in startup procedure.For this reason, people are equipped with retarder at the propeller-shaft place.When electric current passed through the coil assembly of retarder, coil assembly produced magnetic field, rotor (impeller) and the relative high speed revolution of stator (coil panel), and the rotor cutting magnetic line forms current vortex, produces powerful magnetic torque, acts on transmission shaft, and the transmission shaft rotating speed is slowed down fast.People adopt mechanical drive to link to each other with stretcher, control the electric current of importing in the retarder by the effect stretcher, the existing mechanical driving device has only one grade of open and close action, when promptly stepping on stretcher, switch motion, connect the retarder power supply, retarder acts on transmission shaft, and the transmission shaft rotating speed slows down fast.And in the actual travel process, car speed need slowly slow down, if having only one grade of open and close action, the anxious phenomenon of stopping then can occur, and it is also dangerous to cause chaufeur or passenger to feel under the weather.
Summary of the invention
The purpose of this utility model provide a kind of can be many gears slow down, the special-purpose foot-operated electric mechanical switch of automobile retarder simple in structure.
The utility model is achieved through the following technical solutions.
The special-purpose foot-operated electric mechanical switch of a kind of automobile retarder comprises stretcher, automobile brake controller, and it is characterized in that: this foot-operated electric mechanical switch also comprises shell, micro-switch, shifting block, drive link and spring; Micro-switch is installed and is electrically connected in the enclosure and with the automobile brake controller, and shifting block is installed in an end of drive link, and ring spring is enclosed within on the drive link; Shifting block is provided with the gear that is positioned at diverse location, and after shifting block moved to diverse location with drive link, the gear on the shifting block was stirred different micro-switchs.
Described drive link is positioned at a sliding sleeve, and spring is positioned between drive link and sliding sleeve, and sliding sleeve is installed on the shell.
Micro-switch in the described shell is three pairs, respectively closed assembly both sides in the enclosure; Described shifting block is positioned at the centre of three pairs of micro-switchs, and the gear on the shifting block is with the micro-switch position corresponding six grades.
Gear on the described shifting block is stepped.
The described retarder that is electrically connected with the automobile brake controller is a current vortex retarder.
The utility model compared with prior art has the following advantages.
Owing to be provided with two pairs of micro-switchs that are electrically connected with the automobile brake controller in the shell in the special-purpose foot-operated electric mechanical switch of the utility model automobile retarder, when stretcher progressively up lifts, the drive link that links to each other with stretcher moves right in sliding sleeve under the effect of compression spring tension force, and drive link drives shifting block simultaneously and moves.Gear on the shifting block triggers different micro-switchs respectively after moving to diverse location with drive link, and then starts automobile brake controller, the speed of slowing down automobile.

The specific embodiment
Below in conjunction with accompanying drawing the special-purpose foot-operated electric mechanical switch of the utility model automobile retarder is described in further detail.
As shown in Figures 1 to 4, the special-purpose foot-operated electric mechanical switch of automobile retarder comprises shell 1, micro-switch 2, shifting block 3, drive link 4, spring 5, stretcher and automobile brake controller.The three pairs of micro-switchs 2 are stacked in the both sides in the shell 1 respectively, and each micro-switch 2 all is electrically connected with the automobile brake controller.Shifting block 3 is positioned at the groove of crossing of three pairs of micro-switchs, 2 centres, upper-lower position place, shifting block 3 two sides has six grades of stepped gears 31, because each gear lays respectively at different positions, shifting block 3 is in the moving process of turning right, and each gear triggers the contact 21 on the corresponding position micro-switch 2 successively.Shifting block 3 is installed in the left end place of drive link 4, and drive link 4 is positioned at sliding sleeve 6, and sliding sleeve 6 is installed on the shell 1, and spring 5 is positioned at drive link 4 and 6 of sliding sleeves and ring set on drive link 4, and stretcher acts on the right-hand member of drive link 4.Under the roof pressure of stretcher, spring 6 on the drive link 4 is in compressive state, when slowly becoming flexible stretcher, drive link 4 is past moving right under spring 5 tension force effects, thereby drive shifting block 3 toward moving right, shifting block 3 gear 31 on the right side at first triggers the contact 21 on the micro-switch 2, and sends actuation signal for the automobile brake controller, slows down the speed of automobile; When shifting block 3 continues past moving right, trigger the contact 21 on the micro-switch 2 successively, respectively organize coil power thereby connect current vortex retarder successively, progressively slow down the speed of automobile, thereby reach the purpose of slowing down step by step.
