Technical field
The invention belongs to wheelchair brake field, specially a kind of wheel chair motor power-off braker.
Background technology
Existing brake motor generally includes casing assembly, electrode main shaft, the fixation extended from inside to outside in casing assembly
Stator frame, rotor rack in casing assembly etc..Machine winding is set on stator frame, while magnet is set on rotor rack,
Power driven rotor frame is exported by the cooperation of magnet and machine winding to rotate, and then drive motor main axis, realize dynamic
The output of power.In order to realize instant, the accurate brake of brake motor, the generally afterbody in brake motor sets an electromagnetism and stops
Car, when machine winding is powered, electromagnetic brake energization adhesive is now not braking to motor, motor normal rotation output power；Work as electricity
When machine winding is powered off, electromagnetic brake power-off promotes brake block to be braked under the action of the spring.Existing wheelchair brake is mainly
Using spring compression friction plate, locked rotor, so that braking motor.The shortcoming that this kind of mode is present：Braking pad wear is big, and work(
Consumption is big.
The content of the invention
Goal of the invention：It is contemplated that overcoming that the power consumption that existing wheelchair friction catch mode is present is big, serious wear asking
Topic, proposes a kind of new wheel chair motor power-off braker.
Technical scheme：A kind of wheel chair motor power-off braker, including motor, the rotating disk, adjusting screw, the set that are provided with draw-in groove
Cylinder and the brake bar, electromagnet and the spring that are located in sleeve；Rotating disk is fixed on motor shaft, synchronous with motor holding all the time
Motion；Bearing part is provided with rotating disk, is connected with bearing part inner ring after brake bar is passed from sleeve one end；The brake bar other end
It is connected with electromagnet, electromagnet abuts spring, spring can adjust thrust by the adjusting screw for being screwed in the sleeve other end；Electromagnetism
Iron and brake bar can be slided in sleeve along x-axis；During energization, electromagnet compression spring backward in the presence of electromagnetic field, electricity
Magnet drives brake bar that bearing part is maintained at into rotation disk center, motor rotation；During power-off, the magnetic fields of electromagnet disappear,
Spring discharges compression stress, promotes electromagnet, electromagnet to promote brake bar to drive bearing part to stick into any draw-in groove of rotating disk forward,
So that rotating disk stops operating, motor stops.
Further, also including support block and support baseboard, sleeve is supported on support baseboard by support block, supports bottom
Plate is fixed on motor.
Further, the support block be two pieces, respectively with electromagnet and spring outside sleeve at fix.
Further, the sleeve is fixed by screws in support block.
Further, the support baseboard is fixed by screws on motor.
Further, the rotating disk is fixed by screws on motor shaft.
Beneficial effect：Compared with prior art, the present invention can greatly reduce braking motor power consumption, save electric energy, reduce
Cost, and small, long lifespan of wearing and tearing.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is schematic diagram of the invention；
Fig. 3 is view of the present invention in motor rotation；
Fig. 4 is view of the present invention in motor braking.
Specific embodiment
Below in conjunction with accompanying drawing, case study on implementation of the invention is described in detail；
As Figure 1-4, a kind of wheel chair motor power-off braker, including motor 1, rotating disk 2, bearing part 3, brake bar 4,
Sleeve 5, electromagnet 6, spring 7, adjusting screw 8, support block 9 and support baseboard 10, the periphery of rotating disk 2 are provided with draw-in groove, brake bar
4th, electromagnet 6 and spring 7 are located in sleeve 5.Rotating disk 2 is fixed on motor shaft, keeps being synchronized with the movement all the time with motor；Rotating disk
Bearing part 3 is provided with 2, is connected with the inner ring of bearing part 3 after brake bar 4 is passed from the one end of sleeve 5；The other end of brake bar 4 and electricity
Magnet 6 is connected, and electromagnet 6 abuts spring 7, and spring 7 can adjust thrust by the adjusting screw 8 for being screwed in the other end of sleeve 5；Electricity
Magnet 6 and brake bar 4 can be slided in sleeve 5 along x-axis；During energization, electromagnet 6 compresses bullet backward in the presence of electromagnetic field
Spring 7, electromagnet 6 drives brake bar 4 that bearing part 3 is maintained at into the center of rotating disk 2, motor rotation；During power-off, the magnetic of electromagnet 6
Field action disappears, the release compression stress of spring 7, promotes electromagnet 6, electromagnet 6 to promote brake bar 4 to drive bearing part 3 to stick into forward
Any draw-in groove of rotating disk 2 so that rotating disk 2 stops operating, motor stops.
In the present embodiment, the rotating disk 2 is fixed by screws on motor shaft, keeps being synchronized with the movement all the time with motor；
The inner ring of bearing part 3 is connected with brake bar 4, can be slided along x-axis in sleeve 5；Electromagnet 6 abuts spring 7, can be in sleeve 5
Slided along x-axis；Adjusting screw 8 is tightened on the least significant end of sleeve 5 by screw thread, holddown spring 7, and according to pretightning force demand not
Together, the length of adjusting screw precession is different；Sleeve 5 outside electromagnet 6 and spring 7 is consolidated by two pieces of support blocks 9 and using screw
It is scheduled on support baseboard 10；Support baseboard 10 is fixed by screws on motor 1.
As shown in figure 3, during coil electricity, compression spring 7 backward in the presence of electromagnetic field of electromagnet 6, and by spring 7
Restoring force keeps balance, and bearing part 3 hangs over the leading portion end of brake bar 4, and positioned at the center of rotating disk 2, motor runs well.
As shown in figure 4, during coil blackout, magnetic fields disappear, the release compression stress of spring 7 promotes forward electromagnet 6 and system
Lever 4, drives bearing part 4 to stick into any draw-in groove of rotating disk 2 so that rotating disk 2 stops operating, and motor stops.
Compared to the mode of braking of transmission, small, long lifespan of wearing and tearing greatly reduces braking motor power consumption to the present invention, saves
Electric energy, reduces cost.
