Description
Technical field
The utility model relates to a kind of dc electric car parts, especially relates to a kind of accelerator components of dc electric car.
Background technology
The accelerator of existing dc electric car is divided into two kinds: manual accelerator and foot-propelled accelerator.Manually the outward appearance of accelerator and two-wheeled motorcycle throttle control handle are approximate, adopting Hall aerotron 49E or 3503 is the groundwork electronic component, two magnet homopolarities relatively are clipped in the middle the Hall aerotron, do the motion of 20mm camber line shape with the interior radius of circle of 16mm, thereby make the change of voltage of the 5V vdc of input, then this voltage change signal is transported to speed setting controller at output stage realization 0.82V-4.35V.And the cross sectional shape of the main body profile of foot-propelled accelerator can be divided into oblong, approximate square and cylindrical, and inside holds Hall aerotron and magnet, also is provided with pedal or the treadle of making arcuate movement simultaneously.
All there are many shortcomings in the accelerator of these two kinds of forms.1, manually accelerator can not be prevented rainwater.This is owing to must leave certain clearance between turning handle and the fixed parts, turning handle is rotated flexibly, can't stop rainwater to enter just because of this, cause input anodal and the short circuit of output cathode or the short circuit between the input both positive and negative polarity, produce " driving " and " dead car " phenomenon.And the chaufeur right hand can not break away from manual accelerator turning handle during travelling, and makes limitation of activity.2, foot-propelled accelerator volume is big, parts are many, complex structure.And its installation generally is on the floor of right side vehicle body or under the floor, and generally all being provided with brake pedal in this side, the floor has cross member of frame, makes that the installing space of foot-propelled accelerator is limited, only adapt to indivedual Large Electric cars, can not on middle-size and small-size battery-driven car, install and use.
The utility model content
The purpose of this utility model just provides a kind of Novel DC battery-driven car foot-propelled accelerator, has simple in structure, easy for installation, the fast well behaved characteristics of increase and decrease.
For achieving the above object, the utility model adopts following technical scheme: this dc electric car foot-propelled accelerator, its improvements are: fixed frame inside is provided with the groove of an end opening, be provided with pressure retracing spring, work slide block in the groove, the upper end of work slide block is provided with stretcher, and described pressure retracing spring, work slide block can prolong this groove and slide; A side of described work slide block is provided with sliding tray, is provided with magnet, Hall aerotron in the sliding tray, and another side relative with this side is provided with the sliding stroke position-limited trough, is provided with the stroke limit bolt in the sliding stroke position-limited trough; Described stroke limit is bolted on the fixed frame.
Further improvement in the technical proposal is: described magnet is two, lays respectively at the two ends of work slide block sliding tray, and the homopolarity of two magnet is relative.
Further improvement in the technical proposal is: described Hall aerotron is positioned in the middle of two magnet.
Further improvement in the technical proposal is: the bottom end face of described fixed frame and the central axis of fixed frame have angle.
The utility model dc electric car foot-propelled accelerator has following characteristics: 1. anti-rainwater effect is good.Even experiment that direct upper vertical from the foot-propelled accelerator is downward or spray water downwards in 45 ° of oblique angles is perhaps directly put into water with it, short circuit phenomenon can not appear, and battery-driven car still can cruising.2. volume is little.Use Hall aerotron 49E or 3503 all can install and use, and be not subjected to the restriction of locus as the large, medium and small type dc electric car (three-wheel, four-wheel) of control element.3. test on examination ripple device, square wave forms equilibrium.During operation, starting is steady, increase and decrease speed is freely smooth and easy.4. features simple structure, saving in material can significantly improve production efficiency.

Fig. 2 is the A-A cutaway view of the utility model dc electric car foot-propelled accelerator.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
See also Fig. 1 to shown in Figure 2, of the present utility model being constructed as follows among the figure: be used for supportive body and be fixed in fixed frame 1 on the body platform of chaufeur right side, the base rear and front end of fixed frame 1 is respectively equipped with the bolt hole, and the central axis of its bottom end face and fixed frame 1 has angle, generally according to the distance calculation angle of adult's heel to the pedal forward position.Anterior inside in fixed frame 1 from top to bottom is provided with the pig-tail wire hole, and Hall aerotron pig-tail wire 8 is passed in this hole.The upper end of Hall aerotron pig-tail wire 8 connects with three utmost points of Hall aerotron 5, and the lower end connects with the exit of electronic speed setting controller.Be provided with the groove 10 of an end opening at the inside center line place of fixed frame 1, from bottom to top be provided with pressure retracing spring 4, work slide block 2 in the groove 10, pressure retracing spring 4 contacts with the end face of work slide block 2.Side in fixed frame 1 also is fixed with stroke limit bolt 7.
A side of work slide block 2 is provided with sliding tray 12, is provided with magnet 6, Hall aerotron 5 in the sliding tray 12.Magnet 6 is two, lays respectively at the two ends of sliding tray 12, and the homopolarity of two magnet 6 is relative.Upper side in fixed frame 1 is provided with a square hole 11, and Hall aerotron 5 inserts from this hole and is positioned at two magnet, 6 centres, and Hall aerotron 5 adopts 49E or 3503.Another side relative with sliding tray 12 is provided with sliding stroke position-limited trough 9 on work slide block 2, and stroke limit bolt 7 is positioned at this sliding stroke position-limited trough 9.The lower part of work slide block 2 is positioned at the groove 10 of fixed frame 1, and its installation site is determined by stroke limit bolt 7.Work slide block 2 can prolong groove 10 with pressure retracing spring 4 and slide, and stroke distances is limited by stroke limit bolt 7.
Upper end at work slide block 2 also is fixed with stretcher 3.The lower edge length of stretcher 3 surpasses square hole 11 and the stroke limit bolt 7 on the fixed frame 1, enters effectively to prevent rainwater.
During assembling, earlier pressure retracing spring 4 is put into the groove 10 of fixed frame 1, put into the work slide block 2 that coats grease again, tighten stroke limit bolt 7.Then Hall aerotron 5 is inserted square hole 11 on the fixed frame 1 to sliding tray 12, and leave the gap between the sliding tray 12.Simultaneously, usefulness insulative water-proof glue embedding and the fixedly exposed portion of welding and the square hole 11 of Hall aerotron 5.Hall aerotron pig-tail wire 8 passes from the pig-tail wire hole of fixed frame 1.At last, slide block 2 tops and the stretcher 3 of will working is fixing.
During work, step stretcher 3, drive work slide block 2 and two magnet 6 slide up and down, and make the change of voltage of the output stage generation 0.82V-4.35V of Hall aerotron 5, through speed setting controller signal is amplified, thereby the realization battery-driven car are started to walk, stopped and speed transformation again.
