Description
(1) technical field:
The utility model relates to a kind of health and fitness facilities, specifically is a kind of novel energy-saving rowing exercise equipment.
(2) background technology:
Racing boat is an aquatics programme, uses its muscle strength by the rower, makes the tool bar with oar and rowlock as lever and strikes, and makes ship rower's boating of advancing dorsad.Rowing can effectively improve the cardiovascular of human body and respiratory system function, strengthens whole-body muscle strength, regulates the nervous system balance, helps improving the general level of the health of human body.
Simulate above-mentioned action naturally of rowing the boat, be applicable to the motion of gymnasium and family, temper position musculatures such as hand leg waist, take exercise effectively and stretch muscle group, exercise to the back is particularly evident, can alleviate the back symptom of aching, and the physiology stream that greatly improves the pain in the back muscle group simultaneously is active.Rowing exercise equipment is applicable to little at ordinary times movable crowd, is particularly suitable for being sitting in for a long time the white collar who works before the computer.
Rowing machine fitness equipment one is kind of a novel body-building apparatus, and nowadays polytype production marketing is also arranged on the market, and most products adopts pneumatic cylinder that the resistance of motion is provided, and presses the quantity of pneumatic cylinder, can be divided into single pneumatic cylinder rowing machine and two pneumatic cylinder rowing machine.
Single air pressure slide rail rowing machine height is non-adjustable, and the handle motion track is a circular arc, but this single pneumatic cylinder rowing machine is simple in structure, is easy to carrying, deposits.
Two pneumatic cylinder slide bar rowing machine height are also non-adjustable, the slip seat board adopts the four-wheel slide bar type, this rowing machine adopts the device of two pneumatic cylinders, can bear bigger pressure, service life is longer, and the movement locus of drawing slurry is a circular arc, and the motion process resistance is constant, most in addition rowing machine top has one and is used to show momental display, can understand the correlation circumstance of motion for the sporter.
Above product is carried out deep research as can be known, and there are following three big shortcomings in most in the market products:
1, the handle motion track is straight line or circular arc, can not simulate bent rowing truly.
2, the pulling force of handle can not change with the variation of movement locus.
3, the mechanical energy that can not rationally utilize motion and produced.
(3) utility model content:
At the weak point of above-mentioned various rowing machines, the purpose of this utility model provides a kind of novel energy-saving rowing exercise equipment of real simulation bent rowing.
Can realize the novel energy-saving rowing exercise equipment of above-mentioned purpose, foot-operated and the slip seat board of arranging before and after comprising on the frame, the frame of slip seat board both sides is provided with shakes the drag devices that the rise to shaking sizing device that is provided with on sizing device and the frame produces resistance, and different is that the described sizing device that shakes comprises crank and crank and rocker mechanism.Crank and rocker mechanism is made up of crank, rocking bar and connecting rod, crank is provided with near foot-operated, rocking bar is provided with near the slip seat board, following (end) end of crank and rocking bar and frame hinge dress, the connecting rod two ends are adorned with (top) end hinge that goes up of crank, rocking bar respectively, (end) end is fixed on the connecting-rod head of adorning with the rocking bar hinge under the crank, and (top) end is handgrip on the crank.
Described shaking in the sizing device, handgrip is the motive power of crank and rocker mechanism, handgrip is a rise from foot-operated reverse paddle campaign towards slip seat board direction, this moment, drag devices produced resistance, the opposite direction of handgrip is returned the oar motion and is backhaul, this moment, motion produced resistance because drag devices is only to rise, and it is less that backhaul (being the counter clockwise direction of body builder's arm) motion is produced resistance, the rise of handgrip and backhaul track are the prolate ellipse of an inclination, and therefore the energy real simulation goes out these four actions continuously of blade entry, paddle, water outlet, time oar of paddle.
For the angle of inclination that makes the handgrip movement locus reduces, near real action, the hinge of crank bottom can be decorateeed the hinge of a little higher than rocking bar bottom and decorate setting, can realize the very little angle of inclination of prolate elliptical orbit like this.
Height and brachium according to human body, after optimal design, shaking each preferred ranges of size of sizing device is: crank length is 180mm～220mm, rocking bar length is 500mm～540mm, length of connecting rod is 550mm～590mm, and it is 500mm～540mm that the hinge of crank bottom is decorateeed the distance of decorateeing with the hinge of rocking bar bottom, and the line that two hinges are decorateeed becomes 10 °～15 ° angles with horizontal line, crank length is 300mm～340mm, and the angle of crank and connecting rod is 90 °～100 °.
The selected drag devices of the utility model comprises direct current generator, ratchet and transmission mechanism.Transmission mechanism comprises driving wheel and drive sprocket axle, driven pulley and follower shaft.Driving wheel is connected with drive sprocket axle is coaxial, and the drive sprocket axle two ends are that the hinge of rocking bar bottom, both sides is decorateeed and drive sprocket axle axle head and rocking bar are connected, and drive the forward and reverse rotation of drive sprocket axle during the rocking bar swing, by the driving wheel Drive ratchet; Ratchet and driven pulley are connected with follower shaft is coaxial, and the motion of driven pulley is delivered to the output wheel on the direct current generator output shaft.Single veer of ratchet should correctly be set, ratchet and ratchet interlock when the motion rise of crank in the ratchet, the motion rise of crank finally is delivered to direct current generator, overcome the resistance square acting of motor, reach the purpose of exercise, ratchet and ratchet when the motion backhaul of crank in the ratchet skid, and are blocked the stressed less and light return of crank to direct current generator transmission campaign.
The two ends of described follower shaft can be used as the hinge of crank bottom, both sides and decorate, but the follower shaft axle head is to interlock with crank, and crank dallies on the follower shaft axle head, so no matter to be rise or backhaul, the rotation mutually noninterfere of the rotation of crank and follower shaft.
On the output shaft of direct current generator flywheel is installed, flywheel is the bigger disc-like part of a kind of rotary inertia, can store and discharge kinetic energy, and the use of flywheel will reduce the rotating speed of motor fluctuation, be beneficial to electrification energy storage.
Between driven pulley and the output wheel speed change gear can be set, change the rotating speed and the moment of resistance of direct current generator, reach different exercise intensities by the change of gearratio.
Direct current generator also has the function of generating concurrently except that resistance is provided, give monitor power supply with it, makes display reflect the moving situation of exercise in good time.
Advantage of the present utility model:
1, the utility model adopts optimal design method to calculate the toggle of gained, and its rocking bar is as driving link, and its movement locus is similar to ellipse, and the motion of hand when more match is rowed the boat experiences for the person taking exercise with more real boating.
2, resistance mechanism adopts the resistive torque of generator, can the form that person taking exercise's kinergety is converted to electric energy be stored, and leaves the electric energy that comes and can use for display device, also can reach purpose of energy saving for other small-power low-voltage electrical equipment uses.
3, parts commonly used such as bicycle chainwheel, chain, ratchet, speed change gear are formed transmission mechanism and be used for design of the present utility model and make, can reduce manufacturing cost.
4, adopt ratchet can make the sporter stressed when the simulation slurry, and stressed very little during overfall, simulated real boating preferably, can finish corresponding body-building function and effect.
