Abstract
The invention relates to a space mechanism for guiding the curves of hands for breaststroke. A forearm rod is connected in series with an upperarm rod through a ball pair; the upperarm rod is connected in series with a body plate through a ball pair; the forearm rod is connected with a ball pin pair located on a rear sliding block of a base through a connection rod, wherein one end of the connection rod is provided with a ball pair; the upperarm rod is connected with a front sliding block of the base through a connection rod, wherein two ends of the connection rod are provided with ball pairs; and the body plate is connected with the front sliding block of the base through a movable pair. When the practitioner holds the forearm rod to do exercise, the curves of hands for breaststroke can be guided so that the swimming strokes of the practitioner can be normalized.
Description
Affiliated technical field
The invention belongs to the space mechanism field, be specifically related to realize the space mechanism of breaststroke hand curve guiding.
Background technology
As everyone knows, mostly present locus guiding mechanism is plane mechanism, and mostly guide tracks is straight line guiding and circular arc guiding, and mostly driving link is motor or internal combustion and driving, also is not the space mechanism that driving link is realized the guiding of breaststroke hand curve at present with the arm,
Summary of the invention
Arm stroke for standard practitioner in fitness equipment; Help the user in the process of exercise, to know from experience guiding and the standard of fitness equipment to its action; The present invention provides a kind of space mechanism, is driving link with people's big arm, realizes the guiding of hand curve in the breaststroke arm stroke.
The technical solution adopted for the present invention to solve the technical problems is:
This mechanism uses ball secondary in a large number, and the ball pair is composed in series by a shaft coupling and bearing, and shaft coupling provides two rotational freedoms, and bearing provides a rotational freedom.Before armed lever connect through the secondary and big armed lever of ball, big arm is connected with body through ball is secondary, preceding armed lever has the connecting rod of ball pair through an end and is connected with sphere-pin pair on the base rear slider, armed lever is connected with the base front-slider through the connecting rod that two ends have the ball pair greatly.Body is connected with the base front-slider through moving sets.When human arm has 53 grades of secondary mechanism freedoms of 65 grades of pairs of 8 members with mechanism before mechanism combines is 8*6-6*5-5*3=3; When people's arm with after mechanism combines; Increase a member; 3 grades of pairs of 5 grades of pairs increase by two constraints, and the free degree becomes the design philosophy of the man-machine unification of 1 embodiment.Mechanism freedom is unique, and curve is unique to be confirmed.
Mechanism freedom is 1, and in the cotter way shape of sphere-pin pair, the shape of cotter way is by breaststroke hand curve projection entirely for preceding armed lever TRAJECTORY CONTROL.The shape and the data of breaststroke hand curve calculate through setting up the pose equation.Calculate data and image through MATLAB, be carved into cotter way according to data image.
The beneficial effect of patent of the present invention is, path and amplitude that can standard breaststroke practitioner arm stroke, and the aiming drill person learns breaststroke.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the schematic diagram of mechanism before human arm combines with mechanism
Fig. 2 is a human arm and schematic diagram of mechanism after mechanism combines
Fig. 3 is a sphere-pin pair photo in kind
The application of Fig. 4 the present invention in the breaststroke fitness equipment
Secondary 3 big armed lever 4 moving sets 5 front-sliders 6 rear sliders 7 bodies of 1 preceding armed lever 2 balls among Fig. 1
1 breaststroke hand curve guide, 2 lock mechanisms, 3 bodies 4 mechanism's 6 slideways of kicking one's legs among Fig. 4
The specific embodiment
In the embodiment shown in fig. 1, human arm is with before mechanism combines, and mechanism has 53 grades of pairs of 65 grades of pairs of 8 members, and mechanism freedom is 8*6-6*5-5*3=3
In embodiment illustrated in fig. 2, human arm increases a member with after mechanism combines, and 3 grades of pairs of 5 grades of pairs increase by two constraints, and the free degree becomes 1.
In the embodiment shown in fig. 4, breaststroke hand curve guide and lock mechanisms in series, the two does as a wholely to connect with body, body with kick one's legs mechanisms in series, the three places on the slideway jointly.
Claims (6)
