Abstract
The damping unit used for muscle exerciser, multi functional integrated exerciser and stimulation training apparatus is composed of friction plate, relative movement part and damping regulation and control system, and features quantitative stepless regulation of damping value, monodirectional or bidirectional equaldamping or bidirectional unequal damping, damping value controlled by computer, and synchronous operation with detecting, display and memory systems.
Description
The present invention relates to a kind of damping unit that is used on the apparatus for developing muscle.
The damping unit of existing apparatus for developing muscle by its mechanism and structure, is divided into pouring weight formula, flexible type, hydraulic pressure (or pneumatic type) and friction belt type.
Pouring weight formula damping unit be can with one group of pouring weight of the perpendicular direction ascending, descending of horizontal plane, with gravity as damping; In the application of force stroke, weights stack is raised and has gravitational potential energy, and in the idle stroke, therefore weights stack gravitate and falling, can only provide unidirectional damping; And in the idle stroke, the person taking exercise receives by the effect of power, and muscle does not loosen process; When weights stack falls back to lower dead center, percussion is arranged, the exercise load is big more, and this percussion is strong more.Regulate damping value owing to must increase and decrease the quantity of pouring weight, therefore, can not realize step-less adjustment; Be difficult for damping value is carried out dynamic regulation.
The flexible type damping unit is elastomer (as spring, a rubber bar etc.), and the elastic restoring force that produces during with its strain is as damping.In the application of force stroke, elastomeric deflection increases with the increase of stroke, elastic restoring force also changes thereupon, therefore, in the whole application of force stroke, the less stable of damping, elastomer is under the effect of elastic restoring force in the idle stroke, resile, the person taking exercise receives the passive effect of elastic restoring force, and muscle does not loosen process; And this damping unit can only provide unidirectional damping, and the adjusting of damping value realizes by increasing, subtract elastomeric quantity, so, can not step-less adjustment, also be difficult for carrying out dynamic regulation.
Hydraulic pressure (or pneumatic) formula damping unit is hydraulic cylinder (or cylinder), is damping with the cylinder inner fluid to the active force of piston.The adjusting of damping value must be adjusted the flow and the pressure of cylinder inner fluid, and therefore, system is complicated; Volume is also bigger, is difficult for carrying out evolution.
The friction belt type damping unit is tough belt friction mechanism, is damping with the frictional force between friction band and friction pulley.Because the moment of friction that tough belt friction mechanism produces has directionality, so it can only provide unidirectional damping, and its volume is bigger, is difficult for shifting one's position.
The objective of the invention is to for apparatus for developing muscle provides a kind of damping unit, it not only volume little, in light weight, be easy to shift one's position, the damping value that provides is big, and damping value is stable, the stepless quantitative adjusting of its damping value energy be easy to realize dynamic regulation, and system is simple.It can provide bidirectional damper and unidirectional damping, and the idle stroke that the unidirectional application of force is taken exercise does not have passive power effect, and muscle can be loosened, and realizes the process of " application of force-loosen-application of force ", does not have impact phenomenon in the use.
The object of the present invention is achieved like this: it comprises friction plate, relative motion part and damping regulator control system.
Friction plate comprises two or more sets sheets or plate-like friction piece, and the contact-making surface between the friction piece constitutes rubbing surface.
Relative motion comprises that partly several can produce the object of relative motion, is to bear external action, and drives each friction plate group and make the member of relative motion (according to needs, also can have the effect of friction piece concurrently).
The damping regulator control system can be the assembly of mechanism and manual regulating device or system, it also can be the assembly of mechanism and automatic control system, it can carry out static state, dynamic or quiet, the continuous adjustment and the control that dynamically replace to the positive pressure value between rubbing surface, thereby realizes the static state to damping value, dynamic or quiet, the regulation and control that dynamically replace.
With the mutual alternate combination of the friction piece of each friction plate group, and with corresponding relative motion partial fixing separately, the damping regulator control system applies and is used for friction piece, make and receive specific normal pressure between each rubbing surface, do the time spent when being subjected to external force (or moment of face), promptly have relative motion trend between the relative motion part or produce relative motion, simultaneously, each rubbing surface promptly produces the frictional damping that hinders its motion.
The present invention compared with prior art has following characteristics:
Compact conformation, volume are little, in light weight; The damping value that provides is big; Be easy to changing location; Damping value is stable; Can carry out stepless quantitative adjusting to damping value, and be easy to realize dynamic regulation; System is simple; Series, parallel, concurrent aces by several these devices connect or series-parallel connection, multi-faceted multiple spot damping can be provided and two-way equivalent arc or two-way non-equivalence damping can be provided; If matched with unidirectional mechanism, then can provide unidirectional damping, there is not passive power effect in one-way force applied reciprocating idle stroke, muscle can be loosened, realize the process of " application of force-loosen-application of force "; There is not impact phenomenon in the use.Adopt the serial apparatus for developing muscle of this device applied widely, be not only applicable to body-building, fitness, medical rehabilitation and corrective motion, also be applicable to the training aspect; Can satisfy that firm static is taken exercise, dynamic property is taken exercise and etc. the exercise of moving property; Can be matched with detection system, display system and memory system, realization is to observing synchronously and measure with the corresponding physical quantity of various force application locations and physiology of exercise index and sport biomechanics state in the application of force exercise process, store by existing memory system,, analyze and research by reproducing; Also can in the damping regulator control system, adopt programmable amount of exercise control system, realize that the sportsman trains under no coach situation on the scene, and training process is stored in the memory system, after the reproduction, check by the coach, also can be by monitoring, according to the concrete condition in the training, the training program that conversion is different; Also can realize the simulation application of force exercise of specialized movement action, in order to athletic dynamic stereotype.
Structure of the present invention is provided by following two embodiment and accompanying drawing thereof.
Fig. 1 is the schematic diagram of one of embodiment that the torque type damping is provided of providing according to the present invention;
