Detailed description of the invention
Describe technical scheme of the present invention by specific embodiment below, following instance is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
Word " front ", " afterwards ", " left side ", " right side " of middle use are described below, respectively with reference to the direction shown in figure 1.
As shown in Figures 1 to 5, the electronics shifting operation mechanism major part of the present embodiment, comprises gearshift panel 18, connects base 16, and the inverting seat 10 of the spatial structure between panel 18 and connection base 16 of shifting gears.
Inverting seat 10 comprises shift fork body 26 and control circuit board 28.Described shift fork body 26 comprises gearshift track groove 30 and handle bar 22.The handball head 14 that is exposed to gearshift panel 18 outsides is connected with handle bar 22, and permanent magnet 24 is arranged on handle bar 22 bottom end faces.Described handle bar 22 and shift fork body 26 use set pins are fastenedly connected, and move along track groove 30.In mark groove 30, have three static operating positions, the concrete distribution of operating position is position 1, position 2 and position 3 as shown in Figure 5.Permanent magnet 24 is motion simultaneously together with handle bar 22, and dead position and aforesaid operations position are consistent.Inverting seat 10 bottoms are provided with control circuit board 28, are distributed with the hall device corresponding with the operating position of above-mentioned handle bar 22 32 in control circuit board 28, and particular location is D, N and R, corresponding with position 1, position 2 and position 3 respectively, distribute as shown in Figure 4.Hall components and parts in circuit card are responded to the magnet positions in track groove, thereby judge the position of handle bar, then export corresponding electric signal.The electric-control system of battery-driven car is accepted after this electric signal, identifies the shifting intention of chaufeur, makes car load shifting operation.
In control circuit board, to each position in these three positions, the dissimilar electric signal of corresponding output two-way, ensures the accurate and redundancy processing of signal.Meanwhile, in the time that R keeps off, also the signal of backing-up lamp relay is controlled in one of extra output.
In the present invention, electronics shifting operation mechanism has three gear definition, as shown in Figure 5.D gear is defined as forward gear, when automobile is during in normal driving process, uses this gear; The gear on D gear the right is N gear, i.e. neutral, and in the time that vehicle stop moves, electronics shifting operation mechanism should be in this position; The rearward position of N gear is R gear, i.e. backward gear.In the time of vehicle rollback, use this gear.Meanwhile, gearshift can be exported a backing-up lamp control signal, realizes the backing-up lamp function of the bright tailstock in position.Handle bar 22 can pass through shift fork body 26, along " L " type track groove 30, rests on successively D gear, N gear, the R gear any position in putting, as shown in Figure 3 b.
Chaufeur is positioned at the handball head 14 on handle bar 22 tops by control, operating handle bar 22 is realized the variation of shifting operation mechanism position.In the present invention, handle bar 22 bottoms are furnished with permanent magnet 24.And control circuit board 28 is just in time positioned at permanent magnet 24 bottoms, upright position.The position of Hall components and parts 32, just in time the gear positions represented with gearshift track groove 30 is corresponding, as shown in Figure 2 and Figure 4.
In the time that chaufeur is stirred handball head 14 and shifted gears, shift fork body 26 enters corresponding gear along track groove 30.Be positioned at the magnet 24 of handle bar 22 bottoms, move to the top of the hall device 32 in control circuit board 28.This shift position changes, and causes the variation of hall device 32 magnetic flow, makes the interior decision circuit of control circuit board 28 and the dissimilar electric signal of switching value circuit output two-way, as shown in Figure 6.
Electric gear change mechanism in the time of each position output signal logic and voltage range as follows:
Signal 1 signal 2 signal 3 signal 4 signal 5 signal 6 signals 7
Position 1 (D) 0101100
Position 2 (N) 1001000
Position 3 (R) 1100011
Wherein signal 1 to signal 4 is followed successively by: SW1-SW4, and logical one represents that voltage is 3.2 ± 5%V; Logical zero represents that voltage is 1.75 ± 5%V.Signal 5, signal 6 and signal 7, logical one represents that voltage is 12 ± 5%V; Logical zero represents that voltage is 0 ± 5%V.
Referring to figs. 2 to Fig. 6, in the time that magnet 24 moves to D gear and puts, the sensed conducting of D gear hall device, and the hall device of other positions is not switched on, now logic processing circuit 41 output signals 1, signal 2, signal 3 and signal 4; Switching value treatment circuit 42 output signals 5 and signal 6; Backing-up lamp signal circuit 43 output signals 7.Electric-control system entire car controller 44 adopts corresponding matching circuit to accept two-way redundant signals.Car load backing-up lamp circuit 45 relays receive backing-up lamp signal 7 and export.This part belongs to general knowledge for the staff in this area with common knowledge, is not described in detail in this.
The present invention adopts the mode of hall device induction, judges the drive range of handle bar, has avoided physical construction and the direct of electrical structure to contact, and has extended service life.Each drive range is exported by two dissimilar electric signal redundancies, has improved reliability and particularity that drive range is expressed.Meanwhile, the also function of integrated backing-up lamp control of gearshift.Effectively be applicable to pure electric vehicle system.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
