Abstract
The utility model discloses an electric vehicle gear controller adopting a three-polar permanent magnet, which comprises an operation rod, a gear detection unit and a gear control unit, wherein the gear detection unit comprises a Hall element and a permanent magnet, the Hall element is connected with the gear control unit, the permanent magnet is arranged on the operation rod, and corresponds to the Hall element, the permanent magnet is in a strip shape, and is divided into three poles which are sequentially connected, wherein the polarity of the left end pole and the polarity of the right end pole are the same, and are different from the polarity of the middle pole, and the length of the left end pole or the right end pole is smaller than that of the middle pole. In the utility model, the three-polar permanent magnet is utilized for replacing the single-polar permanent magnet of the existing gear controller, the pole distribution length of the surface of the permanent magnet can be accurately controlled through the manufacture process of the permanent magnet, thus effectively complementing the mechanical deviation during the mechanical design and assembly of the gear controller. Simultaneously, the three poles of the permanent magnet are distributed so as to prevent the crosstalk among signals, so that the operation is more accurate.
Description
Technical field
The utility model relates to the automatic controller on the traffic tool, particularly a kind of electric vehicle gear controller of employing three polarity permanent magnets.
Background technique
Existing automotive electronics selector is to interact by Hall element and the permanent magnet that is arranged on the operating handle, when sensing operating handle and being in different gears, this signal can be transferred to the gear detection unit by data/address bus, by gear control unit calculation process, carry out communication with the automobile general control system, thereby realize associative operation.
In the vehicle automatic gear shifting operating device that adopts electronic gear shifter, P, R, N, D retaining normally realizes by the Control of Automobile gearbox shifting, and exports the Control of Automobile gearbox to quicken (Tip+) or slow down (Tip-) by electrical signal after being transformed into manual mode.
Traditional manual mode is to respond to Hall element respectively by a unipolarity permanent magnet to realize the manual mode purpose quickening or slow down, owing to when mechanism design and assembling, there is error, make the unipolarity permanent magnet can not respond to Hall element accurately and effectively, the disabler of may make acceleration, slowing down, perhaps in use, crosstalking of signal for faster or reduce-speed sign might be taken place.
Self-shifting manual mode also can adopt sensitive switch to realize the acceleration and the deceleration of manual mode, but the stability of sensitive switch and life-span thereof are less better relatively, are made its disabler by misoperation easily during use.
The model utility content
In view of this, the purpose of this utility model provides a kind of electric vehicle gear controller of employing three polarity permanent magnets, by adopting three polarity permanent magnets to replace the unipolarity permanent magnet, the problem of having crosstalked between the signal when having solved manual mode has also overcome the improper problem of operation that gear controller causes because of mechanical deflection.
The purpose of this utility model is achieved through the following technical solutions: the electric vehicle gear controller of employing three polarity permanent magnets of the present utility model comprises operating handle, gear detection unit and gear control unit; Described gear detection unit comprises Hall element and permanent magnet, described Hall element and gear control unit link, described permanent magnet is set on the operating handle and corresponding setting with Hall element, described permanent magnet is a strip, be divided into the left end magnetic pole, middle part magnetic pole and right-hand member magnetic pole three parts that link to each other successively, wherein, the polarity of left end magnetic pole and right-hand member magnetic pole is identical and polarity both and middle part magnetic pole is different, and the length of described left end magnetic pole or right-hand member magnetic pole is all less than the length of middle part magnetic pole.
Further, the length ratio range of the length of described left end magnetic pole or right-hand member magnetic pole and middle part magnetic pole is 1: 2～10;
Further, described left end magnetic pole and right-hand member magnetic pole are the N utmost point, and described middle part magnetic pole is the S utmost point.
The beneficial effects of the utility model are:
The utility model utilizes three polarity permanent magnets to replace the unipolarity electromagnet of existing electronic gear shifter, adopt this structure, can control the ironing surface magnetic pole distribution length of permanent magnetism more accurately, thereby effectively remedy the mechanical deflection that selector produces when assembling, simultaneously, left end magnetic pole and right-hand member magnetic pole can be used in and prevent to quicken and the crosstalking of reduce-speed sign, and make operation more accurate.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
