Description
Technical field
The present invention relates to bicycle art, the design method and bike saddle of especially a kind of bike saddle.
Background technology
Bicycle is liked with its low-carbon, environmental protection, convenient feature by masses as a kind of vehicles.With environmental protection
The raising of consciousness, health perception, everybody is more willing to select bicycle as go off daily and the tool taken exercises, and bicycle
Designing and manufacturing level also become better and better, lighter, firm, individual character.
Important component of the vehicle seat as bicycle, directly influences level of comfort when riding.And big portion currently on the market
Vehicle seat is divided mainly to use traditional pattern, i.e.,：By placing elastic pad on plastic cement bottom plate, leather covered layer packet is used in upper surface again
It wraps up in, bottom is supported with supporting mechanism, and supporting mechanism mostly uses head grafting or screw is fixed, tail portion jack or head screw are consolidated
Fixed, two spring of tail portion structure.
Vehicle seat global shape is in head is long and narrow, gradually wide long-narrow triangular mesh, entire seat surface are heaved upwards for tail portion.Its advantage
It is：Long and narrow seat body head can increase stability when riding, and elastic supporting mechanism can play the role of damping, and raising makes
Use comfort level.
But this bike saddle using when defect be also apparent from.First, pain is generated during riding at ischium,
The tail width of mainly bike saddle is inadequate, causes its loaded area inadequate so that the ischium position of user is fallen when riding
In the edge of seat surface, prevent main stress point from effectively being set off, can feel significant discomfort；
Secondly, the generation of compressing perineum is numb during riding, and seat surface heaves the perineum part that can oppress user upwards, and power is anti-
To, it is bigger that riding time of user is more long, the bigger person's perineum part of weight suffers oppression, and can lead to meeting because of blood supply insufficiency
Private parts position and ischium position numbness, pain, the time, which has been grown, to cause to damage to body；
Again, mill femoribus internus generates pain during riding, existing bicycle pedestal head back gradually wide stringcourse position
Size shape design is unreasonable, and the position of bike saddle is all too wide at present, too wide during riding, the thigh of bicyclist
Inside can be interfered, and rub medial thigh skin repeatedly, causes discomfort；
In addition, sultry humidity, the pedestal of existing bike saddle generally are solid elastomeric at ischium and at perineum during riding
There is poor air permeability in pedestal, when riding for a long time, the sweat of skin can not smoothly be discharged, meeting in ride
Cause the bored senses of discomfort such as wet, red and swollen of local skin, also occurs the bike saddle with stomata at present, the stomata on pedestal is in stress
When can be extruded, deform, collapsing, though there is stomata in this way, do not have effective permeation functions yet.
When existing bike saddle is in order to improve rider using bike saddle, stress is concentrated at ischium position, leads to ischium
Bike saddle seat surface horizontal span is adjusted to 200mm, increases the stress surface at ischium by the problem of tract pain, part of the manufacturer
Product, when riding the case where sciatic pain make moderate progress, but still it is uncomfortable, although being primarily due to broaden horizontal span,
Its longitudinal span is still above horizontal span, and seat surface curved design is unreasonable, is not bonded buttocks shape, at seat surface ischium by
Do not stress among seat surface with seat surface head sinking when power is sunk, so at meeting top pressure perineum, generation is uncomfortable, and seat surface is mostly skin
The airtight fabrics such as leather, the sweat of buttocks can not be discharged when riding, stewing heat occur.
It also proposed a kind of bicycle pedestal of the seat surface with curve pocket in existing bike saddle.But it is this voluntarily
The degree of empty avoiding groove shape, seat surface among vehicle seat body span, the angle of inclination of both sides stringcourse and stringcourse indent in length and breadth, exists
Fault of construction.Therefore, though can the soft tissue around ischial tuberosity be dispersed to the stress point for concentrating on ischium originally, due to
Stringcourse width of the pedestal by head is larger, and the scattered range of seat surface stress point is smaller, and bearing area is not big enough, still insufficient
To solve the problems, such as to squeeze perineum and femoribus internus interference friction and ischium pressure sores.
In 104680577 A of application publication number CN, entitled " the personalized saddle design side towards high-end bicycle
A kind of design method of bicycle saddle is disclosed in method ", its purpose is to can tailor suitable different crowd demand
Bicycle saddle, but the design method of this saddle, institute's measured data is extremely more, and multiple data are related to human private position,
Actually measurement is got up very awkward, and operability is not strong, although and integrally being tied with the bicycle saddle that this data and formula obtain
The relatively traditional saddle of structure more meets Human Physiology sitting posture, but the saddle does not have rationally the inner concave curve of pedestal both sides
Design parameter, the interference of bicyclist's femoribus internus can not be reduced.
Invention content

Advantageous effect：
A kind of design method of bike saddle of the present invention, when carrying out bike saddle design using this method, pedestal is respectively taken turns
The shape of wide curve is combined closely with human buttock's profile, the size relationship interdependence between each contour curve of pedestal, succinctly
It is illustrated, it is regular to follow, substantially increase the efficiency of 3D modeling.The bike saddle designed using this method, size ratio
Optimum state is presented in example, shape, and on the basis of ensureing use, maximum possible reduces at pedestal head and stringcourse in thigh
The contact friction of side, and the bicycle pedestal tail portion loading end designed in this approach widens increasing, makes buttocks stress more
Add equilibrium, can effectively reduce the ischium stress degree of bicyclist, avoids the sense of discomfort at ischium position caused by riding for a long time.
In the design method of bike saddle：Pedestal head width W1 is equal to or less than bicycle saddle tube upper end holding tank T's
Centre-to-centre spacing, the determination of W1 width can determine whether pedestal head can cause to interfere to the femoribus internus of bicyclist, according to hair
Person of good sense's Study on Estimating repeatedly, under the premise of meeting bike saddle and being installed with bicycle saddle tube upper end holding tank, the choosing of W1 sizes
It selects and follows that the smaller pedestal head width of size is smaller, and interfere fewer principle with femoribus internus；
The ratio between longitudinal span of pedestal and horizontal span are golden section proportion 0.618 in design method, this Proportionality design is taken to obtain
The pedestal gone out, seat surface tail area is larger, while meeting bicyclist's use, can effectively improve relaxing when bicyclist uses
Appropriateness, because the bigger bearing capacity of the area of seat surface is bigger, stress is more balanced, and stability is better；
The starting point of stringcourse M3a, M3b is：Starting point is consistent with the endpoint of head width W1, and terminal is fallen in maximum transversal span,
Fore-and-aft distance L1 between terminal and starting point and the ratio of longitudinal span are golden section proportion, i.e. L1=0.618 × L, are logical at this
The starting point that W1 determines stringcourse is crossed, the lateral maximum width of stringcourse terminal is determined by horizontal span, passes through longitudinal span
Golden section ratio determines longitudinal maximum distance of stringcourse terminal, the intersection point of stringcourse longitudinal direction maximum distance and seat surface horizontal span
The final position that stringcourse is determined, the stringcourse drawn out in this way is an inclined contour line, on the basis of inclined, by stringcourse
It is designed as inner concave curve, by rider's thigh root diameter dimension, to adjust the opening angle a1 and stringcourse tail on stringcourse head
The opening angle a2 in portion, and then change the indent degree of stringcourse inner concave curve, the pedestal obtained in this way, stringcourse position can be complete
Agree with the radian of bicyclist's femoribus internus, can achieve the effect that be bonded completely and does not interfere；
In design method of the present invention, the determination for stringcourse terminal P7, P8 be it is very crucial because stringcourse will with it is big
Rear contact in leg has position-limiting action, the longitudinal size size of stringcourse terminal, when determining bicyclist's riding to bicyclist leg
Sitting posture can it is forward also rearward, on the basis of the fore-and-aft distance L1 of stringcourse terminal P7, P8 in the present invention, if stringcourse terminal is vertical
It is less than L1 to size, i.e. stringcourse final position is relatively close to pedestal front, and puncta ischidiacum falls present Middle face when seating, then stringcourse is whole
Region can generate severe interference to leg muscle on earlier pedestal angle at point；If the longitudinal size of stringcourse terminal is more than
There are many L1, i.e., stringcourse final position can also become smaller therewith relatively close to pedestal rear portion, then seat surface loading end, and bicyclist is big when riding
Leg can compare rearward, body sitting posture also can therefore and rearward, ischium drop point also can rearward, then the front of avoiding hollow groove may be right
Male genetic position causes to interfere, and loading end becomes smaller, and cannot fully support the pressure at ischium, and then influence comfortable riding
Degree, is optimal proportion so taking stringcourse final position determined by golden section proportion.
When drawing seat surface avoiding hollow groove, the starting point on avoiding hollow groove head is determined with the endpoint at the both ends pedestal head width W1, by
This is it can be appreciated that the width of avoiding hollow groove head starting point is the overall profile of avoiding hollow groove using pedestal head width W1 as reference
Curve shape wide in front end, middle and back is narrow, tail portion is wide, the width of front end the widest part are less than or equal to the width on pedestal head,
That is W4≤W1, the width at the most narrow place in middle and back and the ratio of front end widest part width are golden section, i.e., W5=0.618 ×
The width of W1, tail portion are more than width of the width less than front end the widest part of middle and back, because of thus obtained empty avoiding channel profiles
Shape is consistent with the muscle profile at human thigh root to perineum, while such avoiding hollow groove can either meet gas permeability,
Contact of the thigh root with perineum part can be utmostly avoided, friction, the compressing to the position are reduced or avoid completely；
The side view curve of avoiding hollow groove is in the low smooth curves in the high head in tail portion, this is but also the whole seat surface of pedestal is high in tail portion
The low shape in head, because human body is when riding, upper limb leans forward, leg pedaling, and the supporting point of body is largely fallen in buttocks,
The high head in seat surface tail portion of pedestal is low, can pole be bonded the flow profile of buttocks as far as possible, meeting pedestal bearing stability
While, keep buttocks pressure dissipation uniform, mitigates bearing capacity of the bicyclist in riding at ischium, improve comfort；Slow down stern
Portion's muscle acid is swollen, stupefaction；
Further, angle of inclination 10o≤a4 ＜ 25o of the side view curve of avoiding hollow groove contour line, this also determines pedestal
The angle of inclination of whole seat surface selects such a angular range, will not be too big because of seat surface angle of inclination, causes ride
In, the buttocks of bicyclist, will not be too small because of seat surface angle of inclination from seat surface slide downward, and dispersion buttocks pressure is not achieved
Purpose, while seat surface angle of inclination is too small, can also cause the interference between femoribus internus and pedestal；
Centered on longitudinal axis Y, symmetrical point P3, P4 are drawn on transverse axis X, the width between P3, P4 is W2,
W2 is using human body ischial tuberosity width data as reference, and seat surface central point P9, P10 are with cross central line M2a, M2b and to indulge
Intersect to center line M5a, M5b, the lateral distance of P9, P10 are consistent with W2, it is possible thereby to determine the position of seat surface central point
It sets and is got with reference to human body ischial tuberosity width, seat surface horizontal span W3 is 2 times of W2, since ischium is the main of human body
Stress point, after position of the stress point on seat surface is determined, using the seat surface horizontal span of 2 times of ischial tuberosity width,
The buttocks supporting surface that can obtain a bigger will concentrate on the pressure dissipation of puncta ischidiacum originally when buttocks is placed in the face
Onto the stress surface of entire buttocks, effectively disperse the pressure of ischium, improves comfort when riding, also, transverse center
The curve stage casing of line M2a, M2b form the abducent curve pocket centered on seat surface central point P9, P10 to lower recess,
So that buttocks is wrapped in curve pocket, further disperse the pressure of ischium, improves comfortable riding；
Further, it is that reference obtains since seat surface central point is with human body ischial tuberosity width data, during riding,
It will produce a degree of deformation after seat surface stress, it is possible to so that avoiding hollow groove is narrowed because of stress, and then be likely to result in empty avoiding
Slot is closed, and is influenced using effect, therefore, the two side of avoiding hollow groove is designed as skewed so that the section of avoiding hollow groove is in by upper
The diminishing shape under combines the shape of seat surface that can disperse pressure to the both sides of avoiding hollow groove, can protect so in this way
The structural strength for holding avoiding hollow groove makes it be in optimal use state always；
Described seat surface cross central line M2a, M2b and transverse axis X are oblique so that seat surface is in the low shape in intermediate high both sides
Shape, leg scrunches downwards when the advantage is that riding, and inclined seat surface shape is more in line with Human Physiology curve.
Bike saddle of the present invention, the ratio between the longitudinal span and horizontal span of pedestal are golden section
Example, this shape make the loading end of pedestal widen increasing, meanwhile, pedestal is meeting pedestal in the low shape in the high head in tail portion
While bearing stability, the form of buttocks after fitting upper limb that can be most probably leans forward keeps buttocks pressure dissipation uniform, in this way
Bicyclist will not be too big because of the bearing capacity at buttocks ischium in ride, and causes gluteus carnic acid swollen, numb；
Pedestal includes elastic pad, bottom plate, and multiple stomatas are evenly equipped on elastic pad, and stomata is embedded with stomata support tube, can have
Caused stomata is flattened after effect avoids the problem that pedestal stress, fully meets the ventilative requirement of pedestal；
The intermediate position of elastic pad upper surface is equipped with avoiding hollow groove, and avoiding hollow groove is directly through to tail portion from the head of elastic pad,
The design maximum possible of avoiding hollow groove avoids friction and compressing of the pedestal to perineum part, further increases usage comfort,
Also there is good gas permeability；
Position that left and right two supporting surfaces of pedestal are connected with avoiding hollow groove is high, left and right two supporting surfaces from high to low gradually to
Outside tilts, and forms the symmetrical inclined support surface in left and right both sides, and leg scrunches downwards when riding, and inclined seat surface shape is more
Meet body curve；
The position that the supporting surface of elastic pad corresponds to human body ischial tuberosity is equipped with curve pocket, which meets human body
Ischium knot away from size will concentrate on the pressure dissipation of puncta ischidiacum originally to entire buttocks when buttocks is placed in the supporting surface
On stress surface, effectively disperse the pressure of ischium, improves comfort when riding；
The bottom supporting mechanism includes integrally formed holder, and holder includes the straight figure of symmetrical holder, the straight figure of holder
Front end be folded upward to form U-shaped rotating part, the end of rotating part is folded upward to be formed for installing fixed pars convoluta, and holder is straight
The rear end of figure extends outward, the straight figure of holder extend outwardly position tail end upwards and tilt backwards extend to form tail portion company
Section is connect, the pars convoluta of holder is fixed on backplane header by pressing plate, and the linkage section of holder is fixed on the tail portion of bottom plate.Since holder is straight
The U-shaped rotating part maximum outer profile of figure is concordant with pedestal head maximum outer profile so that and the support span of the straight figure of holder is big,
In this way when being gripped with seat pipe, the range of fore-aft adjustable makes the adjustable range of pedestal center of gravity and shows than broad
There is the adjustable range of bicycle center of gravity consistent so that pedestal disclosure satisfy that versatility, and user can be according to personal need in riding
It asks and is adjusted, centre of body weight Forward or rear shifting when avoiding riding caused by pedestal bottom supporting mechanism can not be adjusted, before making
Limb stress is excessive, arm generates pain；
In scheme one, the pars convoluta of the bottom supporting mechanism is stuck in bottom plate arc groove in pressing plate limiting slot, can not only rise
To good position-limiting action, additionally it is possible to the reasonability for improving pedestal stress, after pedestal increases shock-absorbing spring, when spring by
The pars convoluta of force compresses, pedestal stern settlement, the bottom supporting mechanism on pedestal head can be such that pressure mainly makees along pars convoluta axis rotation
For spring, when being fixedly connected of standard bicycle seat head use is effectively avoided the occurrence of, because plasticity occurs after bottom slab stress
The problem of deformation leads to bottom plate fixed connection point periphery bending crack, improve the service life of pedestal.
