Abstract
The invention discloses a stepping motor feedback system suitable for an adjustable rear protection device of a heavy duty vehicle. The system consists of three parts including a stepping motor, shafts and gears and a photoelectric encoder, wherein after the stepping motor is connected with a power supply, the shaft of the motor is connected with the shaft provided with the gears by a coupling, and is connected with the photoelectric encoder by the coupling, and the rotation angles of the gears and the required angular difference are detected by the photoelectric encode, and the rotation angles and the required angular difference are fed back to the stepping motor so as to perform further adjustment, and therefore, the rotation accuracy of the stepping motor is improved to a great extent.
Description
Technical field
The invention belongs to the automotive engineering field, relate to a kind ofly for the rear on the vehicle, or rather, the present invention relates to a kind of stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles.
Background technology
At present, domestic and international research about the heavy-duty vehicle rear, mainly based on the Purely mechanical rear, vehicle frame is for being rigidly connected after Purely mechanical rear and the heavy goods vehicles, the Purely mechanical rear not only affects the crossing ability of heavy goods vehicles, can sail the damage that causes rear because of vehicle is up on abominable ground again, can't guarantee the safeguard function that it is good.In addition, because the rear protecting of heavy-duty vehicle is higher apart from ground, when the vehicle of the types such as car or SUV and heavy goods vehicles knock into the back, easily cause the vehicles such as car or SUV " to pierce " heavy goods vehicles rear overhang part, cause great injures and deaths.
Adopt electromechanical integration technology both can be when having guaranteed collision the safety of front vehicle, can improve again the crossing ability of vehicle, the protection vehicle is when normally travelling, its rear is difficult for damaging.Present part vehicle rear can't be by the relevant laws and regulations of vehicle rear protecting.In addition, the adjustable vehicle rear protecting based on electromechanical integration of having developed at present, its cost is higher, and weight is larger, also is difficult for popularizing and promoting.Above-mentioned phenomenon has produced adverse effect for the life-span of vehicle safety, rear and the crossing ability of vehicle.So we have researched and developed the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles, carry out automobile rear bumper and carry out safe regulation and control with auxiliary.
Summary of the invention
Technical matters to be solved by this invention is to have overcome existing stepping motor to have rotational angle deficiency or excessive problem, and a kind of stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme to realize: the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles is divided into stepping motor, axle and gear and photoelectric encoder three parts composition.
After wherein stepping motor and power supply join, its axle is connected with the cogged axle of peace by coupler, this axle links to each other with a photoelectric encoder by coupler again, by photoelectric encoder detection of gear rotational angle and required differential seat angle and feed back to stepping motor further to regulate.
Compared with prior art the invention has the beneficial effects as follows:
1. the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles of the present invention accurately detects the angle of axle rotation and feeds back to stepping motor by photoelectric encoder and checks.
2. the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles of the present invention is simple in structure, easy for installation; In addition, the cost of the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles of the present invention is lower, is easy to the marketization.
3. the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles of the present invention is safe and reliable, and the output signal of stepping motor is highly sensitive, and precision is high.
4. but the stepping motor feedback system that is applicable to the adjustable rear protecting of heavy goods vehicles of the present invention has stronger generalization.
