Description
Technical field
The present invention relates to a kind of tube shaped electric machine, be meant a kind of tube shaped electric machine specifically by the non-electromagnetic force to release brake device.
Background technology
Be fixed on after tube shaped electric machine, a kind of and reel are connected and be used for the device of equipment such as folding and unfolding garage shutter door, shutter, rolling screen door, sunshade and projection screen on door, the window.Generally by drive motors, output shaft, deceleration device and brake gear are formed, its brake gear is generally by electromagnet, spring, brake block and brake disc are formed, its course of work under "on" position is as follows: before the energized, the brake block of tube shaped electric machine and brake disc frictional engagement, tube shaped electric machine is in braking state, connect the tubulose motor power, electromagnet in the brake gear gets electric generation electromagnetic force, brake block is by the electromagnetic force adhesive, the spring force and the brake disc that overcome spring are thrown off, drive motors work this moment drives the output shaft running, tube shaped electric machine is in normal operating conditions, and during outage, electromagnet loses electromagnetic force, spring recovers deformation brake block is pushed up go back to the origin-location, makes the motor braking of running again with the brake disc frictional engagement.
The brake gear of this type of tube shaped electric machine is all realized by electromagnetic force, it must be tube shaped electric machine ability operate as normal under the situation that electricity is arranged, but emergency case such as power failure appear in the life unavoidably, if it is electronic that tube shaped electric machine only depends on, running into power failure then can't turn round, thereby also can't the folding and unfolding door curtain, bring many inconvenience to live and work, for solving the trouble that has a power failure and bring, need to tube shaped electric machine a manual device to be set, the brake by the artificial disengagement motor of manual operations also makes its running reach the purpose of folding and unfolding door curtain.
Be arranged in the past that manual in the tube shaped electric machine exists all generally that parts are various, complex structure, cost height; Friction is big, useful life is short; Shortcomings such as functional reliability is low.
Utility model patent ZL02265408.9 discloses a kind of tube shaped electric machine with arrangement of clutch, mainly comprises motor, outer tube, holder, driving head, torsion spring assembly, connector and mandrel.Be provided with worm gear and worm screw in holder, an end of mandrel is fixedlyed connected with worm gear, and the other end is fixedlyed connected with connector, and connector is fixed by screw and outer tube; Worm screw is fixed in the holder by thrust bearing, and the end of worm screw is connected with swing arm.The cross sectional shape of worm screw is a semicircle that axial vane surface is pruned along tooth root, and swing arm is connected with extension spring, by the phase-locked company on flexible axle and flexible axle support and the door guide rail.Meet when having a power failure, compress rotation with the key insertion, extension spring drive swing arm is revolved and is turn 90 degrees, thereby the drive worm screw is revolved and turn 90 degrees, axial vane surface of worm screw and worm-wheel shaft line parallel like this, the self-locking action of worm gear hour, outer tube and holder float, this moment, available hand rotated driving head with outer tube, reached the purpose that opens and closes rolling screen door.This technical scheme adopts worm gear and worm screw to cooperate and realizes manual operation, has bigger resistance but cooperate between worm gear and the worm screw, throws off relatively difficulty, and friction is big, and the damage of parts is more serious, influences its useful life; And both positions are difficult for cooperating fully when engaging, and cause dislocation easily, and functional reliability is low, need often maintenance, bring many unnecessary troubles to operating personnel.
And utility model patent ZL200420026080.X discloses a kind of manually operated tube shaped electric machine that makes things convenient for, mainly by reel, the transmission mechanism motor that motor and decelerator are formed, shaft coupling, between manual-operating mechanism composition transmission mechanism and the manual-operating mechanism shaft coupling is installed, shaft coupling is main for it, driven member prolongs spool shaft to mechanism that realization mutually combines and throws off, the shaft coupling driving link is driven by manual-operating mechanism and moves axially, driven member links in machine shaft, manual-operating mechanism is rotatable rod member, manual-operating mechanism and shaft coupling driving link have the position that is in contact with one another, and the surface of institute contact site is to make the shaft coupling driving link realize the cam structure face that axially moves back and forth.These technical scheme parts are various, and structure is very complicated, and cost improves relatively, and the matching property between each parts requires high, thereby processing and manufacturing difficulty is big, global reliability is poor, useful life is short.
Summary of the invention
The invention provides a kind of can be electronic also can manually operated tube shaped electric machine, by on the brake gear of tube shaped electric machine, setting up a draw-gear, when having a power failure, artificially the brake of tube shaped electric machine is thrown off by draw-gear, and cooperate torsion spring device simulation tube shaped electric machine in the running that has under the electric situation, can realize the purpose of folding and unfolding door curtain equally, so just solve the difficult problem of door curtain folding and unfolding when having a power failure.
A kind of tube shaped electric machine by the non-electromagnetic force to release brake device, comprise and being used for and the fixing mounting panel of body of wall, support, shell and place drive motors in the shell, deceleration device, output shaft and brake gear, brake gear comprises electromagnet, be fixed on the spring on the electromagnet, the brake block and the brake disc corresponding that link to each other with spring with brake block, drive motors one end cooperates with brake disc and links to each other, the other end links to each other with output shaft through deceleration device, described brake gear is provided with draw-gear, draw-gear one end is connected on the brake block, and the other end is drawn the shell of tube shaped electric machine.
Described draw-gear adopts stay cord.
Described draw-gear adopts pull bar.
Operation principle of the present invention is as follows: when needing that under power-off condition tube shaped electric machine carried out manual operations, the pulling stay cord is located at the outer part of tube shaped electric machine shell, the brake block that drive links to each other with the stay cord other end, make brake block overcome the elastic force of spring, throw off with brake disc, the brake of tube shaped electric machine is by artificial disengagement, tube shaped electric machine is in non-braking state, cooperate the torsion spring device that tube shaped electric machine is turned round artificially, simulate it, can realize the purpose of folding and unfolding door curtain equally in the running that has under the electric situation.
Compare with similar manually actuated tube shaped electric machine, the present invention has remarkable advantages:
1, simple in structure, parts are few, on the basis that does not change original tubulose electric machine structure, only set up a draw-gear on the brake gear of tube shaped electric machine, thereby also do not increased production cost basically.
2, operation is very simple, in the time of need carrying out manual operations to tube shaped electric machine, only needs pulling stay cord or pull bar, and the brake of tube shaped electric machine is thrown off, and cooperates the torsion spring device can realize the purpose of its folding and unfolding door curtain again.
3, friction is little between each parts, and damage is few, long service life.
