Abstract

The utility model relates to an automobile steering wheel rotation prompt and display device which comprises an embedded type processor, an analog-digital (A/D) converter and a display screen, wherein the A/D converter and the display screen are respectively and electrically connected with the embedded type processor. The automobile steering wheel rotation prompt and display device is characterized in that 36 pieces of small magnet are arranged under the edge of a steering wheel; the interval angle between every two pieces of adjacent small magnets is 10 degrees; 36 light-emitting diodes (LEDs) are arranged at the edge of the steering wheel; the 36 LEDs and the 36 pieces of small magnets have the relationship of one-to-one correspondence and are electrically connected with the embedded type processor; two Hall sensors are arranged just under the steering wheel side by side; the two Hall sensors correspond to the small magnets arranged under the edge of the steering wheel and are electrically connected with the A/D converter. The automobile steering wheel rotation prompt and display device can be used for displaying the concrete rotation angle of the steering wheel, namely, the positions of tires so as to help a driver to accurately master the steering wheel and reduce the misoperation, thus being especially suitable for an unskillful driver.

Description

A kind of vehicle steering rotates the prompting read out instrument

Technical field

the utility model is a kind of electronic counting equipment, and particularly a kind of vehicle steering rotates the prompting read out instrument.

Technical background

Chaufeur, when steering wheel rotation, does not often know oneself to have turned how many angles, do not know wheel has changed how many angles, in which direction yet? make when turning or moveing backward and can't accurately grasp direction, and produce maloperation.In order to address this problem, people have developed the device of energy display direction dish rotational angle." automobile steering wheel rotating position display device " as CN 202193118 U bulletins, comprise the magnet ring that is arranged on bearing circle transmission shaft bottom, the telltale that is evenly distributed on the polylith magnet on magnet ring, the hall sensing assembly corresponding with magnet, the control circuit be connected with the hall sensing electrical component and is electrically connected to control circuit.Chaufeur when driving, by watching telltale, can be understood the position of rotation of vehicle steering, thereby accurately controls direction of traffic.But it is inadequate only depending on the display prompts chaufeur accurately to control direction of traffic, therefore, also requires further improvement.

Summary of the invention

The purpose of this utility model is to provide a kind of vehicle steering and rotates the prompting read out instrument, its can the display direction dish concrete angle of rotating, the position of tire, help chaufeur accurately to grasp bearing circle, reduce misoperation, be particularly suitable for unskilled chaufeur.

A kind of vehicle steering described in the utility model rotates the prompting read out instrument, comprises flush bonding processor, the A/D converter be electrically connected to flush bonding processor respectively and read-out, it is characterized in that:

Be provided with 36 small magnets below the bearing circle edge, between every adjacent two small magnets, interval is 10 °, is provided with 36 light-emitting diodes on the bearing circle edge, and 36 light-emitting diodes and 36 small magnets are corresponding and be electrically connected to described flush bonding processor one by one;

Be provided with side by side two Hall elements under bearing circle, described two Hall elements are corresponding with the following small magnet that is located at the bearing circle edge and be electrically connected to A/D converter.

The utility model is work like this, when steering wheel rotation, if the Hall element on the left side is introduced into work, the direction dish is to anticlockwise, the number of times of writing down according to Hall element, if just forward under small magnet, converting is just the integral multiple of 10 °, if between two small magnets, get intermediate value and calculate; By A/D converter, it is changed over to digital signal, import in flush bonding processor, by flush bonding processor, it is processed, draw the angle that bearing circle turns over, and, according to calibration, draw the angle that wheel turns over, by it, all be presented on read-out, and, in this process, the position of light-emitting diode is the position that chaufeur forwards to, make that chaufeur is clearer knows the bearing circle position.Make the driver clearly know the direction that bearing circle turns over, angle, and the wheel direction and the angle that turn over.

Compared to the prior art the utility model has the following advantages: not only it can be by the concrete angle of rotating of read-out display direction dish, can also pass through lumination of light emitting diode, the angle and the turned position that make navigating mate be clear that bearing circle turns over, more effective help chaufeur is accurately grasped bearing circle, reduces misoperation and accidents caused.

Fig. 2 is schematic block circuit diagram of the present utility model;

Fig. 3 is the utility model workflow schematic block diagram.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, Fig. 2 and Fig. 3, shown a kind of vehicle steering rotates prompting read out instrument, the A/D converter 4 that comprise flush bonding processor 5, is electrically connected to respectively with flush bonding processor and read-out 6;

Be provided with 36 small magnets 2 below bearing circle 1 edge, between every adjacent two small magnets, interval is 10 °, be provided with 36 light-emitting diode 7,36 light-emitting diodes and 36 small magnets corresponding and be electrically connected to described flush bonding processor 5 one by one on bearing circle 1 edge;

Be provided with side by side two Hall elements 3 under bearing circle 1, described two Hall elements 3 are corresponding with the following small magnet 2 that is located at bearing circle 1 edge and be electrically connected to A/D converter 4.

36 light-emitting diodes 7 of installation on bearing circle 1, they are directly over each small magnet.Corresponding these 36 light-emitting diodes 7 of installing are electrically connected to flush bonding processor 5.When Hall element 3 enters work, flush bonding processor 5 is given the signal of light-emitting diode, causes lumination of light emitting diode, navigating mate is clearly seen and turned over angle and turned position, plays eye-catching effect.Namely certain piece small magnet has been responded to Hall element light-emitting diode 7 corresponding to this piece small magnet top is luminous.
