Wherein, the top of described shift switch shell is provided with through hole; the one mistake proofing knob coaxially arranged with bracket axle is installed in described through hole; the outer side wall of described mistake proofing knob is connected with limit damping ring by damping piece; described limit damping ring is fixed on described bracket axle; be coaxially arranged with a cut-offing protecting switch in described mistake proofing knob, described mistake proofing knob rotates predetermined angle, for pressing described cut-offing protecting switch.
Wherein, described damping piece comprises elastic component and coupled damping block.
Wherein, described elastic component is spring.
The beneficial effect of technique scheme of the present invention is as follows:
In such scheme, electric vehicle shift switch gearshift of the present invention changes gearshift mode, traditional driving lever form is improved to rotation mode, eliminate the P shelves of electric vehicle without function definition, add gearshift to misplace function and ensure that drive safety prevents misoperation, be integrated with emergency power off function and improve drive safety; It can not only realize electric automobile gearshift function, and can prevent the gearshift misoperation of driver easily and effectively, and reasonable in design, has practicability.

Embodiment
For making the technical problem to be solved in the present invention, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to electric motor car shift switch P shelves functional redundancy of the prior art, gear shifting structure is single and without the problem of error-disable function, provides a kind of electric vehicle shift switch.
As shown in Figure 1, a kind of electric vehicle shift switch that the embodiment of the present invention provides, comprise shift switch shell 1 and be located at the gearshift execution block 9 in described shift switch shell 1, bracket axle 10, limiting stopper 8, described shift switch shell 1 is coaxially arranged with bracket axle 10, and can relatively rotate, described shift switch shell 1 inwall is fixedly connected with described gearshift execution block 9, described gearshift execution block 9 is rotationally connected with the outer side wall of described bracket axle 10 by the first damping block 5 and the first damping spring 6, produce when making shift switch shell 1 drive gearshift execution block 9 to relatively rotate with described bracket axle 10 and feel and damping sense into position, described limiting stopper 8 is fixedly installed on the outer side wall of bracket axle 10, and be positioned at below described gearshift execution block 9, the outer side wall of described bracket axle 10 is provided with limit spring 7 between limiting stopper 8 and gearshift execution block 9, described shift switch shell 1 drives gearshift execution block 9 to rotate, described gearshift execution block 9 and the surface of contact of bracket axle 10 are provided with corresponding gear contact, realize forward gear D, reverse gear R, the conversion of neutral N.
The top of described shift switch shell 1 is provided with through hole; in described through hole, the mistake proofing knob 3 that arrange coaxial with bracket axle 10 is installed; the outer side wall of described mistake proofing knob 3 is connected with limit damping ring 4 by the second damping block 11, second damping spring 12; produce when mistake proofing knob 3 and described bracket axle 10 are relatively rotated and feel and damping sense into position; described limit damping ring 4 is fixed on described bracket axle 10; a cut-offing protecting switch 2 is coaxially arranged with in described mistake proofing knob 3; described mistake proofing knob 3 rotates predetermined angle, for pressing described cut-offing protecting switch 2.
Gearshift function of the present invention realizes as follows: Gear-shift switch shell 1 is fixing with gearshift execution block 9 machinery, turn clockwise shift switch shell 1 for forward gear, need when being rotated counterclockwise shift switch shell 1 downwards by, spacing obstruction could be departed from, correctly enter reverse gear.First damping block 5, first damping spring 6 coordinates with bracket axle 10 to produce to be felt and damping sense into position.Limit spring 7 and limiting stopper 8 play position-limiting action.While gear enters forward gear D, reverse gear R, neutral N, gearshift execution block 9 mechanically contacts respectively with the contact-making switch on bracket axle 10, by electrical harness, gives gearshift relay, LED signal, while generation gearshift, lights different LED.
Forceful electric power emergency closing function of the present invention realizes as follows: mistake proofing knob 3 is fixed by limit damping ring 4 and part 10 bracket axle, and the second damping block 11, second damping spring 12 coordinates with limit damping ring 4 to produce to be felt and damping sense into position.Mistake proofing knob 3 rotates tilt fixing, and mistake proofing knob 3 contacts respectively with the contact-making switch on bracket axle 10, passes through electrical harness; to D.C. contactor, LED signal; angle is correct, and cut-offing protecting switch 2 just can be pressed, and then controls D.C. contactor to forceful electric power implementation definitely control.
In such scheme, electric vehicle shift switch gearshift of the present invention changes gearshift mode, traditional driving lever form is improved to rotation mode, eliminate the P shelves of electric vehicle without function definition, add gearshift to misplace function and ensure that drive safety prevents misoperation, be integrated with emergency power off function and improve drive safety; It can not only realize electric automobile gearshift function, and the gearshift misoperation of driver can be prevented easily and effectively, cause electric motor car in advance process because extension reverse gear causes motor reversal by mistake, the generation of accident such as infringement vehicle and personal safety etc., switch internal adopts rotary position-limit mechanism, and structure simply substantially prolongs working life, improves durability and reliability.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
