Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.According to it is following explanation and
Claims, advantages and features of the invention will become apparent from.It should be noted that, accompanying drawing is using very simple
The form of change and use non-accurately ratio, be only used to conveniently, lucidly aid in illustrating the embodiment of the present invention
Purpose.
The present invention provides a kind of motor, as shown in figure 1, including magnetic steel of motor 15 and rotor 18, rotor 18
By the encirclement of the magnetic steel of motor 15, the rotor 18 is by its internal current and the magnetic steel of motor 15
Act on and rotated in motor.In preferred scheme, the rotor 18 is coil block.The coil block is
It is made up of multigroup coil, coil is rotatable in the presence of magnetic steel of motor 15 during energization.
Please continue to refer to Fig. 1, the described motor of this implementation also includes the commutator 17 of the connection rotor 18,
And the brush 16 of the connection commutator 17, the brush 16 by electric current for passing through the phase changer 17
The rotor 18 is conveyed to, the commutator 17 is used to maintain the rotor 18 persistently to rotate.Specifically,
Brush 16 be a kind of slide contact member, be the motor fixed part and rotating part between transmit energy or
The device of signal.Preferably, the material of the brush 16 is graphite, leaching fat graphite or metallic graphite carbon.It is described
Brush 16 adds coagulator to be made by pure carbon, and external form is square.When operation, brush 16 is by electricity for motor
Rotor 18 can be conveyed to by phase changer 17.
The described motor of this implementation also includes housing 13 and end cap 12, refer to Fig. 2, and the housing 13 is wrapped
Enclose the magnetic steel of motor 15, the end cap 12 cover the two ends of the housing 13 and seal the rotor 18,
Commutator 17 and brush 16.From Figure 2 it can be seen that cylindrical jacket of the housing 13 for motor, cylinder
The two ends of outer cover are sealed by end cap 12 so that the internal part of motor is able to be transported in the sealing space
OK.
The present invention also provides a kind of magnetic steel of motor, as shown in figure 3, magnetic steel of motor 15 is located at housing 13 and moves
Between son 18.Due to magnetic steel of motor 15 in the process of running probably due to part fragmentation and produce chip, and
Clamping stagnation is between housing 13 and mover 18, so will again be carried out after magnetic steel of motor 15 outer layer covers, one layer of rubber
Assembling, the protective layer 152 for forming outer layer surround the magnet steel body 151, as shown in Figure 4.Now, even if
Later stage causes the fragmentation of magnetic steel of motor 15 because of crackle or impact, and the chip of generation is because the bag of protective layer 152
Wrap up in without departing from magnet steel body 151 or snap in gap.In a preferred approach, the protective layer 152 is bullet
Property protective layer, specific material for example can be rubber.But the present invention does not limit the specific material of protective layer 152
The use of material, as long as protection magnet steel body 151, the effect for preventing chip from overflowing can be reached.It is preferred that square
In case, the thickness of the magnet steel body 151 is 2mm-5mm, and the thickness of the protective layer 152 is
0.1mm-0.5mm.But the present invention is not intended to limit the thickness of the magnet steel body 151 and protective layer 152.Institute
The forming method for stating protective layer 152 for example can be spraying, infiltration or rendering.I.e. by the magnet steel sheet
One layer of elastomeric material of surface spraying of body 151 is forming protective layer 152；Or soaked in the magnet steel body 152
In entering the container equipped with elastomeric material liquid so that the surface of magnet steel body 151 forms rubber cover 152；
Or with brush dip elastomeric material liquid and paint on magnet steel body 151.Above-mentioned is the protective layer 152
Several alternatives of forming method, the present invention is any limitation as not to this.
Please continue to refer to Fig. 1 and Fig. 2, the described motor of this implementation also includes rotating shaft 10, and its connection is described to be turned
Son 18 simultaneously exports the rotation of the rotor 18.The outside of the rotating shaft 10 is arranged with little gear (pinion) 11,
Little gear 11 can connect a transmission mechanism, and the rotation of motor is exported.
The present invention also provides a kind of throttle body, comprising above-mentioned motor and it is improved after magnetic steel of motor.
As shown in figure 5, the throttle body includes the housing 13 of motor 100 and motor 100, motor 100 is connected
Transmission mechanism 200, TPS 300, and cover plate 400.The sealed electric-motor of cover plate 400
100th, transmission mechanism 200 and TPS 300, cover plate 400 and housing 13 provide above-mentioned part
Installation site.Throttle body also includes throttle plate pin 500 and air throttle valve plate 600, the He of throttle plate pin 500
Air throttle valve plate 600 can cooperatively form throttle body air flue with housing 13, for controlling air inflow.For
The control of throttle plate pin 500 and air throttle valve plate 600 realized by motor 100, motor 100 and little gear 11
Coordinate, drive air throttle valve plate 600 that a certain fixed position is rotated or maintained in the air flue.Air throttle
Axle 500 provides the installation site of air throttle valve plate 600, is rotated together with air throttle valve plate 600 on product,
Control air inflow.In above-mentioned control process, the real-time detection throttle plate pin 500 of TPS 300
The anglec of rotation.
Control process when air throttle of the invention specifically applies to automobile is as follows.Stepped on the gas when driver's pin and stepped on
During plate, the information that control unit of engine (ECU) collection efp is provided, and combine vehicle
Actual operating mode, the aperture of precise control electronic air throttle body；While the timely feedback letter of electronic air throttle body
Cease to ECU, form closed-loop control.Specifically, after gas pedal is trampled by driver, pedal angle becomes
Change value is read by ECU, and ECU determines air throttle valve plate aperture according to driver intention, i.e., to throttle motor
Power supply, motor is rotated, and torque is forwarded to valve shaft by motor by transmission mechanism, and valve shaft drives valve plate rotation
Turn, the anglec of rotation is the desired air throttle valve plate apertures of ECU.
In the course of work of above-mentioned motor and air throttle, because the outside of magnetic steel of motor 15 has protective layer
152, even if therefore the later stage cause the fragmentation of magnetic steel of motor 15 because of crackle or impact, the chip of generation because
The parcel of protective layer 152 is without departing from magnet steel body 151 or snaps in gap.
The present invention provides a kind of magnetic steel of motor, including magnet steel body and the protective layer around the magnet steel body,
Increased protective layer can prevent magnetic steel of motor from producing chip because of part fragmentation in the process of running, and clamping stagnation
Between magnet and mover.The present invention also provides a kind of motor and throttle body comprising above-mentioned magnetic steel of motor,
When in use due to the presence of above-mentioned magnetic steel of motor, it is to avoid because the electronic throttle valve plate that magnet steel fragmentation is caused
Clamping stagnation, reduces bad yield rate, PPM values, improves the service life of part, increases the safety of product
Coefficient, with good economic benefit.
Obviously, those skilled in the art can carry out various changes and modification without deviating from the present invention to invention
Spirit and scope.So, if it is of the invention these modification and modification belong to the claims in the present invention and its
Within the scope of equivalent technologies, then the present invention is also intended to including including these changes and modification.
