Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1, the embodiment of the present invention detect comprising the following steps of inclination angle and acceleration with linear hall sensor:
S101: the value of input magnetic-force density is to linear hall sensor;
S102: linear hall sensor process magnetic-force density;
S103: export relevant voltage simulating signal;
In step S101, when acceleration along with object and the inclination angle relative to level ground change, it is downward that the inner ring counterweight of this structure can be tending towards vertical all the time, thus cause inner ring to rotate, this is equivalent to rotate electric vehicle rotary handle, thus causes the magnetic-force density inputing to linear hall sensor to change.
Embodiments of the invention concrete steps:
Step one, the value of input magnetic-force density is to linear hall sensor;
Lienar for Hall element is made up of Hall element, linear amplifier and emitter follower, its output voltage analog quantity; Its output voltage and applied field strengths linear.Within the scope of the magnetic induction density of B1 ~ B2, there is the good linearity, when magnetic induction density exceeds this scope, then present state of saturation.
So when this device inner ring and outer shroud do not relatively rotate, arc-shaped magnet is exactly a definite value for the magnetic-force density value that linear hall element produces; When the inner ring of this device and outer shroud relatively rotate, arc-shaped magnet just and linear hall sensor there occurs relative displacement, this changes causing the value of the magnetic-force density inputing to linear hall sensor.In a word, arc-shaped magnet can input the value of magnetic-force density to linear hall sensor.
Step 2, linear hall sensor process magnetic-force density;
After linear hall sensor receives the value of magnetic-force density, after the effect of the linear amplifier that comprises inside linear hall sensor and these built-up circuits of emitter follower, the magnetic-force density value that it receives can be processed.Different magnetic-force density values after treatment, can obtain different voltage analog signals.
Step 3, exports relevant voltage simulating signal;
Have passed Signal transmissions and the process of previous step one and step 2, linear hall sensor will export corresponding voltage analog signal, the analog quantity that this voltage analog signal is required just.
As shown in Figure 2, the detecting inclination angle and acceleration apparatus with linear hall sensor and mainly contain of the embodiment of the present invention: electric car handle 1, arc-shaped magnet 2, linear hall sensor 3, counterweight 4;
Arrange counterweight 4 in electric car handle moveable annulus bottom, the inside of outer shroud embeds linear hall sensor 3, and the outer round surface of inner ring embeds arc-shaped magnet 2, and during use, outer shroud is fixed on electric bicycle, inner ring can at the internal rotating of outer shroud.
Principle of work of the present invention:
Sensor of the present invention can not direct-driving motor, only be used to the regulating rotary of alternative electric bicycle (handle), based on the gradient and acceleration, the gradient is larger, the output signal of Intelligent power assisting device of electric bicycle is larger, the output signal of twisting wide-angle with handle is suitable, and thus, the electric boosted size of Intelligent power assisting device of electric bicycle (this method) becomes because of slope.
Acceleration and the object angle of inclination with respect to the horizontal plane of object can be measured.When object be subject to acting force produce acceleration or object have an angle of inclination relative to level ground time, due to the effect of inertia, the counterweight that inner ring can be made to add and linear hall sensor produce relative motion, and outer shroud is fixed on electric bicycle, and inner ring can at the internal rotating of outer shroud.Due to based on the gradient and acceleration, larger or the acceleration of the gradient becomes large, and the output signal of Intelligent power assisting device of electric bicycle is larger, and handle to twist the output signal of wide-angle suitable, thus, the electric boosted size of Intelligent power assisting device of electric bicycle becomes because of the gradient and acceleration.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
