Abstract
Description
- The disclosure relates to a braking device, more particularly to a braking device for a motor of an actuator.
- Linear actuators mainly use electric motors and actuating elements, such as worm gears and worm wheels, to actuate leadscrews rotating. Meanwhile, the leadscrews actuate telescopic tubes screwed thereof extending out or retracting. Since the structure and the assembly are simpler and more convenient than pneumatic cylinders or hydraulic cylinders, the linear actuators are widely used in apparatuses, such as sickbeds, electric chairs and other fields that need expansion and retraction.
- Conventional linear actuators are disclosed in EP0662573B and WO2004-027290A2, wherein EP0662573B discloses that an actuator mainly comprises a worm gear, a leadscrew, and a worm wheel assembly fixed at one end of the leadscrew. The worm wheel assembly comprises a worm wheel, a coil spring surrounding the outer peripheral edge of a cylindrical annular body. WO2004-027290A2 seeks to solve the problem in the previous application that a great amount of heat is generated by the friction between the coil spring and the annular body during the movement, and it applies a heat conducting unit to dissipate heat.
- However, the coil spring in conventional linear actuator is fixed, and the cylindrical annular body rotates with the worm wheel, so that heat is generated by the friction between the coil spring and the cylindrical annular body. In addition, the cylindrical annular body is generally made of plastics, so that the heat would cause the cylindrical annular body melting or the coil spring being worn out rapidly. Thus, the lifespan is greatly decreased. Also, the braking effect is achieved merely by linear contact between the coil spring and the cylindrical annular body, which is rotating, for decelerating or braking Since the effective contact areas between the coil spring and the annular body is small, the ability of decelerating or braking is limited.
- One purpose of the disclosure is to provide a braking device for a motor of an actuator. The braking device retracts the coil spring by the elastic force of the elastic unit, so that the braking ring can have a stable braking effect.
- To reach this goal, the disclosure provides a braking device for a motor of an actuator. The motor of an actuator comprises a shaft. The braking device comprises a base, an elastic unit, a braking mechanism and a stopper. The base includes an axial connected section and a placed section formed at a lateral side of the axial connected section; the elastic unit is disposed at the placed section; the braking mechanism is assembled at the axial connected section, the braking mechanism comprises a braking ring sleeved on the shaft and a coil spring tightened to the outer peripheral edge of the braking ring, a first torque arm and a second torque arm extend from the two ends of the coil spring, and the first torque arm abuts one end of the elastic unit; the topper corresponds to the rotational path of the second torque arm and is disposed at the base.
- Moreover, the disclosure may also achieve the following effects. The disclosure assembles the elastic unit, the braking mechanism and the stopper inside the body in advance, so that the assembly process and assembly time of the braking device and the motor of the actuator can be greatly reduced. The braking device can be used in motors of actuators with different braking forces by the use of the adjusting lever. When the braking device of the disclosure is used for the linear actuator, the linear actuator can decline in a steady velocity, so that the user can have comfortable experience. The braking device of the disclosure further has advantages of a simple structure, low costs and a small size.

It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
- Referring to
FIGS. 1 and 2 , the disclosure provides a braking device used for a motor of an actuator. Thebraking device 1 mainly comprises abase 10, anelastic unit 20, abraking mechanism 30 and astopper 40. - The
base 10 can be made of plastics, and it mainly comprises a circular sectorshaped bottom plate 11 and ahoarding 12 extending upward from the peripheral edge of thebottom plate 11. The middle section of thebottom plate 11 has an axial connectedsection 13. The axial connectedsection 13 is ahole 131 set up at thebottom plate 11 and acurve wall 132 extending from the peripheral edge of thehole 131. Also, a placedsection 14 is formed at a lateral side of the axial connectedsection 13, and the placedsection 14 is asemi-cylindrical barrel 141 formed between thebottom plate 11 and thehoarding 12. Further, avertical column 15 extends from thebottom plate 11 and thevertical column 15 is disposed at the front end of thesemi-cylindrical barrel 141 and corresponds to a notch of acurve wall 132. In addition, a fixedcolumn 16 is disposed at the side of thesemi-cylindrical barrel 141 and thevertical column 15, such that screwed units, such as bolts, can pass through and fix with it. - In this embodiment, the
elastic unit 20 is a compressive elastic unit, and it mainly comprises agliding unit 21 and acompressive spring 22. Thegliding unit 21 comprises acylinder 211 and aprotrusion 212 extending from thecylinder 211. Thecylinder 211 is movably disposed inside thesemi-cylindrical barrel 141. Thecompressive spring 22 is disposed inside thesemi-cylindrical barrel 141 and is elastically clamped between thehoarding 12 and thecylinder 211. - The
braking mechanism 30 is assembled at the axial connectedsection 13 of thebase 10, and it mainly comprises abraking ring 31 and acoil spring 32 tightened to the outer peripheral edge of thebraking ring 31. Thebraking ring 31 can be made of metals or plastics. In this embodiment, thebraking ring 31 comprises threecurve plates 311. The inner wall of each of thecurve plates 311 has anoil storage tank 312 disposing therein, and each of theoil storage tanks 312 corresponds to the axial direction of thecurve plates 311. Also, each of the outer walls of thecurve plates 311 has a plurality ofgrooves 313, and each of the plurality ofgrooves 313 is disposed corresponding to the radial direction of the plurality ofcurve plates 311. Thus, thecoil spring 32 can be fixed with each of thecurve plates 311 stably. - A
first torque arm 321 and asecond torque arm 322 extend from the two ends of thecoil spring 32. Thefirst torque arm 321 is disposed between theprotrusion 212 of thegliding unit 21 and thevertical column 15, and thefirst torque arm 321 is abutted by theprotrusion 212. Under the free status, the angle A between thefirst torque arm 321 and thesecond torque arm 322 is between 10° and 50°. Preferably, the angle A is between 20° and 40°. Most preferably, the angle A is 30°. When the angle A is greater than 50° or when the angle A is smaller than 10°, the breaking force is too large or too small so that it cannot be applied. - Moreover, a
stop lever 323 folds inwardly from the free end of thesecond torque arm 322. Thestop lever 323 passes into the intervals formed between any twoadjacent curve plates 311, so as to prevent thecurve plates 311 swinging excessively. - In this embodiment, the
stopper 40 is a fixedstopper 40, and it corresponds to the rotational path of thesecond torque arm 322 and is fixed to thebottom plate 11 of thebase 10. - Referring to
FIGS. 3-5 , thebraking device 1 of the disclosure can be used for amotor 7 of an actuator. Themotor 7 of the actuator comprises ashaft 71 and has ascrew hole 72. For assembling, thebraking ring 31 of thebraking mechanism 30 is sleeved corresponding to theshaft 71, the end surface of the hoarding 12 attaches the back end surface of themotor 7 of the actuator, and a bolt passes through the fixedcolumn 16 so as to be fixed to thescrew hole 72. Thus, the assembling process of thebraking device 1 and themotor 7 of the actuator of the disclosure can be easily accomplished. - As shown in
FIGS. 6 and 7 , when being used, the rotational direction of theshaft 71 is identical to the rotational direction of thecoil spring 32, wherein “identical” indicates that when thecoil spring 32 is a right-handed coil spring and theshaft 71 rotates counterclockwise, thefirst torque arm 321 of thecoil spring 32 is elastically abutted by theelastic unit 20, so that thecoil spring 32 retracts radially and tightens thebraking ring 31, and the braking action is generated by the friction between the inner surface of thebraking ring 31 and the circumferential surface of theshaft 71. When thecoil spring 32 retracts radially, thesecond torque arm 322 swings with the rotation of thebraking ring 31. When thesecond torque arm 322 rotates to the position of thestopper 40, it has a maximum braking force so that theshaft 71 stops rotating. Thus, when themotor 7 of the actuator is used in a linear actuator (not shown in the figure) and the linear actuator is assembled in an electric bed or an electric chair, the downward movement of the deck or the seat back would become more slowly, so that the user can have more comfortable using experience. - In contrast, when the
shaft 71 rotates clockwise, thefirst torque arm 321 of thecoil spring 32 attaches thevertical column 15, so that thecoil spring 32 expands radially. At this moment, thebraking ring 31 is released, so that the friction to the rotation of theshaft 71 is decreased, and theshaft 71 can easily rotate inside thebraking ring 31. Thereby, it can transmit without affecting the performance of transmission of themotor 7 of the actuator. - Referring to
FIG. 8 , thebraking device 1 a further comprises an adjustinglever 50, the hoarding 12 of thebase 10 has ascrew hole 121. The adjustinglever 50 screws to thescrew hole 121 and then is connected with thestopper 40, so that thestopper 40 can move forwardly or backwardly by screwing-in or screwing-out the adjustinglever 50. Thus, it can be used inmotors 7 of the actuator with different braking forces. - As shown in
FIG. 9 , besides the embodiments described above, thebraking ring 31′ of the disclosure mainly has asectional groove 33 at a cylindrical barrel, and thesectional groove 33 is parallel to the axis of thebraking ring 31′. - According to the above descriptions, the braking device used for a motor of the actuator of the disclosure can achieve the purposes and solve the problems met in conventional technologies. Thus, the disclosure involves novelty and inventiveness as well as meets the requirements of patent application. Thus, the application is applied according to Patent Law. The application is kindly requested to be granted for ensuring the right of the inventors.
