Description
Technical field
The present invention relates to a kind of wheel, particularly a kind of integrally formed pushchair.
Background technology
The wheel of perambulator generally includes wheel hub and the tire on wheel hub in the prior art, and wheel hub typically uses metal
Material or hard plastic material are made, heavier mass, are not easy to the storage and carrying of perambulator；Tire is typically using the soft of lighter weight
Material is made, and possesses damping effect；Because the two material is different, after needing to produce separately through mould during the production again
Assembled, technique is cumbersome, causes production cost to remain high.
In addition, being typically attached between wheel hub and tire using the mode such as buckle, gap therebetween be present, during use
Contact site can rub, and reduce the service life of tire, and the inner side of long-term use of rear tyre can be worn, can be led when serious
Bulging of tyre is caused to come off, security is poor.
The content of the invention
For overcome the deficiencies in the prior art, a kind of process of present invention offer is simple, service life is long, can mitigate product
Quality, and can improve the pushchair of product strength.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of wheel, including integrally formed wheel body, the wheel body be disposed with from outside to inside tire portion,
Disc portion and wheel axle portion, the outside of the disc portion are connected with the inner side in the tire portion, inner side and the outside of the wheel axle portion
Connection.
The inside of the wheel body is honeycomb.
The hardness in the tire portion is less than the hardness of the disc portion, and the hardness of the disc portion is less than the wheel axle portion
Hardness.
The width A in the tire portion is more than the width B of the wheel axle portion, and the width C on the outside of the disc portion is less than or waited
In the tire portion width A but more than the width B of the wheel axle portion, the width D on the inside of the disc portion is less than the spoke
The width of thickness C on the outside of portion.
The middle part of the disc portion makes the side end face of the disc portion cave inward to contract.
The tire portion is TPU materials, packed density 20%-80%.
The disc portion is TPU materials, packed density 20%-80%.
The wheel axle portion is TPU materials, packed density 20%-80%.
The inwardly protruding formation boss of middle inside of the wheel axle portion.
The outer surface in the tire portion is provided with anti-slip veins.
The beneficial effects of the invention are as follows：The wheel body of the present invention is integrally formed by 3D printing technique, and technique is simple, car
The inside for taking turns body is honeycomb, both alleviates product quality, improves the intensity of product again；Wheel body from outside to inside according to
Secondary tire portion, disc portion and wheel axle portion, the outside of disc portion of being provided with is connected with the inner side in tire portion, and inner side is outer with wheel axle portion
Side is connected, and tire portion is played a supporting role；Tire portion, disc portion and wheel axle portion use TPU materials, and hardness is incremented by successively,
Tire portion hardness is minimum, has good elasticity and wearability；Disc portion hardness is moderate, has both played a part of excessively buffering, has subtracted
Few vibrations to taking turns axle portion, and can improve the intensity in tire portion, prevent tire portion from deforming；Axle portion hardness highest is taken turns, is connected with wheel shaft
Connect, there is good mechanical strength.
In addition, the middle part of disc portion makes the side end face of disc portion cave inward, serves the work of anti-deformation to contract
With, the mechanical strength of disc portion is enhanced, improves the service life of wheel body, it is safe.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is one of structural representation of the present invention；
Fig. 2 is the two of the structural representation of the present invention；
Fig. 3 is the sectional view of the present invention.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of wheel, including integrally formed wheel body, the wheel body is from outside to inside
Tire portion 1, disc portion 2 and wheel axle portion 3, the outside of the disc portion 2 is disposed with to be connected with the inner side in the tire portion 1,
Inner side is connected with the outside of the wheel axle portion 3, and disc portion 2 is played a supporting role to tire portion 1.The integrally formed side of wheel body
There are numerous embodiments in method, be such as integrally formed using 3D printing technique in the prior art, and for example by different moulds and
The raw material of different formulations are respectively produced the embryo in tire portion 1, disc portion 2 and wheel axle portion 3 to come, and then these have difference
The embryo of characteristic is nested together, and is placed in foaming mould and foams, and is allowed to tire portion 1, disc portion 2 and wheel axle portion 3 and is integrally formed.
In the present embodiment, it is preferred to use technical grade 3D printer carries out printing production, by selecting 20%-80% filling rate, makes wheel
Body is internally formed honeycomb, and technique is simple, both alleviates product quality, improves the intensity of product again.
In the present embodiment, the hardness in the tire portion 1 is less than the hardness of the disc portion 2, the hardness of the disc portion 2
Less than the hardness of the wheel axle portion 3.Furthermore, tire portion 1, disc portion 2 and wheel axle portion 3 use TPU（Thermoplastic poly
Urethane elastomer rubber）Material, but hardness is incremented by successively, and tire portion 1, the and of disc portion 2 are adjusted by adjusting packed density
The hardness of axle portion 3 is taken turns, the range of choice of packed density can be selected between 20%-80% according to needs of production；Such as wheel
The Selective filling density of tire portion 1 is 20%, and hardness is minimum, has good elasticity and wearability；And for example the Selective filling of disc portion 2 is close
Spend for 50%, hardness is moderate, has both played a part of excessively buffering, and reduces the vibrations to taking turns axle portion, and and can improves the strong of tire portion
Degree, prevent tire portion from deforming；For another example it is 80% to take turns the Selective filling density of axle portion 3, hardness highest, with taking turns axis connection, is had well
Mechanical strength.
In the present embodiment, the width A in the tire portion 1 is more than the width B of the wheel axle portion 3, tire portion 1 is played more
Good damping effect；The width C in the outside of disc portion 2 is less than or equal to the width A in the tire portion 1 but is more than the wheel shaft
The width B in portion 3, the width D of the inner side of disc portion 2 are less than the thickness C in the outside of disc portion 2 width, make disc portion 2 more
Tire portion 1 is supported well；The middle part of the disc portion 2 makes the side end face of the disc portion 2 cave inward, spoke to contract
Portion 2 is in hourglass shape, serves the effect of anti-deformation, enhances the mechanical strength of disc portion, and improve wheel body uses the longevity
Life, it is safe.
In the present embodiment, the middle inside of the wheel axle portion 3 is inwardly protruding forms boss 4, makes wheel axle portion 3 in boss 4
Both sides form one respectively and be used to the cavity of bearing be installed, the middle part of wheel axle portion 3 is provided with axis hole, for connecting with rotary shaft
Connect.The outer surface in the tire portion 1 is provided with the anti-slip veins of projection, increase friction, prevents from skidding, further increases perambulator
Security performance.
Embodiment above can not limit the protection domain of the invention, and the personnel of professional skill field are not departing from
In the case of the invention general idea, the impartial modification and change done, the scope that the invention is covered is still fallen within
Within.
