Abstract
The utility model discloses an electronic parking force measurement device, which comprises a sensor, a magnetic element assembly and a spring connected with the magnetic element assembly, wherein the spring is arranged on a supporting seat; one end of the spring is a fixed end; the other end of the spring is limited by the supporting seat; the magnetic element assembly is fixed at the other end of the supporting seat and opposite to a sensor; and a distance is reserved between the magnetic element assembly and the sensor. Compared with the conventional force measurement mechanism, the electronic parking force measurement device has a simple structure and is convenient to operate; when acting force is applied to the supporting seat, a compression amount of the spring is in one-to-one correspondence to a moving amount of the magnetic element assembly, and the intensity of a magnetic field of a magnetic element is correspondingly changed, so that a corresponding relation between an electronic signal and pull force is acquired; and therefore, an electronic control unit (ECU) of an electronic parking assembly can acquire information of a parking force properly.
Description
Technical field
The utility model relates to a kind of device for measuring force, refers to be used for a kind of electronics Parking device for measuring force of automobile industry particularly.
Background technology
Electronics Parking assembly need provide enough drag-line power that automobile is parked on certain ramp, and when reaching required Parking power, electronics Parking assembly stops to continue to increase drag-line power.In addition,, require the Parking drag-line that certain pretightning force is arranged,, require drag-line to stop at the pairing position of pretightning force when each Parking discharges when accomplishing for reducing electronics Parking action time.In sum, the control module (ECU) of electronics Parking assembly needs a kind of device for measuring force can provide drag-line power numerical value in good time, makes that the automobile on the ramp can be parked in good time.Mostly existing device for measuring force is the electronic signal through a kind of sensor passes elastic deformation force, though can realize of the control of electronics Parking assembly to drag-line power, its complex structure, cost is expensive.
Summary of the invention
The technical matters that the utility model will solve just provides a kind of electronics Parking device for measuring force simple in structure, the power on the Parking drag-line is converted into electronic signal passes to electronics Parking ECU, to realize the control of electronics Parking assembly to drag-line power.
For solving the problems of the technologies described above, the electronics Parking device for measuring force that the utility model designed comprises the spring of sensor, magnetic element assembly and connection thereof; Said spring is installed on the bearing; One end of spring is a stiff end, and the other end of spring is spacing by bearing, the other end stationary magnetic element assembly of bearing; The magnetic element assembly is corresponding with sensor, between have distance.
As optimal way, said sensor is the sensor that includes Hall chip, and the distance that exists between sensor and the magnetic element assembly is less than 1.4mm.
Said bearing comprises spring supporting bar, and an end of spring supporting bar is provided with the block of limit spring, and the other end of spring supporting bar is fixedly connected with the magnetic element assembly.
The principle of work of the utility model: the drag-line masterpiece is used on the spring, makes length of spring compressed, can obtain formula F=Kx according to the Hooke theorem, and wherein: F is a drag-line power, and x is an amount of spring compression, and K is a stiffness factor.Magnetic element assembly and spring abutment and spring are connected; Then amount of spring compression x is the amount of movement L of magnetic element assembly; When the magnetic element assembly moved, the corresponding variation took place to the magnetic field intensity of Hall chip in magnetic element, according to Hall effect; Can learn that Hall chip can produce correspondent voltage.Through demarcating, can obtain the corresponding relation that Hall chip produces voltage signal and drag-line power, therefore, electronics Parking assembly ECU can obtain the Parking force information in good time.
The advantage of the utility model: compare with existing force measuring machine, because spring is installed on the bearing, the bearing magnetic element assembly that is connected; Not only simple in structure, easy to operate, and when acting force is on bearing; The amount of movement of amount of spring compression and magnetic element assembly produces relation one to one; Respective change also takes place in the magnetic field intensity of magnetic element, thereby the corresponding relation of the electronic signal of obtaining and drag-line power makes electronics Parking assembly ECU can obtain the information of Parking power in good time.
