The utility model discloses an antiskid lightweight motor of intelligence suitcase gyro wheel, its anti-skidding structure setting through the wheel hub surface can fundamentally solve the phenomenon of skidding of long-time back wheel hub and tire of using to can alleviate the motor weight to a certain extent, realize the lightweight design of motor, promote the motor performance.
Description
Technical Field
The utility model relates to an intelligence suitcase gyro wheel specifically is an antiskid lightweight motor of intelligence suitcase gyro wheel.
Background
With the continuous development of intelligent technology in recent years, more and more intelligent devices are used in life, and an intelligent luggage case is one of the intelligent luggage cases, has the functions of automatically following and avoiding obstacles and the like, and can bring great convenience to people for traveling.
Here, the above implementation of the intelligent function of the luggage case, in which the role of the wheel motor is very large. But at present, the ordinary small motor is directly used for reference to current suitcase gyro wheel structure, and its motor wheel hub passes through smooth outer disc and is connected with solid tyre tight fit, but in the in-service use, because of the tire coefficient of thermal expansion is far greater than wheel hub, simultaneously in addition the ageing problem of tire, the inefficacy phenomenon of wheel hub and tire tight fit can often appear, causes profile and tire to take place the phenomenon of skidding, is difficult to normally drive the tire and carries out work, has seriously influenced the life of gyro wheel.
In addition, for the joint strength needs of satisfying profile and tire, the thickness of wheel hub all has hard requirement, and this not only can increase the consumptive material of wheel hub, increases manufacturing cost, and the weight that also can be whole motor simultaneously aggravates, and this can cause the reduction of motor performance to a certain extent.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model discloses an antiskid lightweight motor of intelligence suitcase gyro wheel, its anti-skidding structure setting through the wheel hub surface can fundamentally solve the phenomenon of skidding of long-time back wheel hub and tire of using to can alleviate the motor weight to a certain extent, realize the lightweight design of motor, promote the motor performance.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an antiskid lightweight motor of intelligence suitcase gyro wheel, includes motor and tire, and the motor outside is equipped with the wheel hub of being connected with the tire tight fit, its characterized in that: a plurality of lower grooves are arranged on the outer circular surface of the hub at intervals along the circumferential direction, and the outer circular surface between every two adjacent lower grooves forms a supporting surface.
Furthermore, the size structure of each lower groove is the same, and each lower groove evenly distributes at interval on the outer disc of wheel hub.
Further, the span of the support surface is greater than the span of the lower groove.
The utility model discloses a low groove that sets up on the outer disc of wheel hub and constitute block antiskid, when the assembly, when the tire that struts contracts, not only form effective tight fit with wheel hub's holding surface and be connected, the place that corresponds the low groove simultaneously can further contract inwards and the arch appears and form block connection structure, its fundamentally has solved the connected mode of current wheel hub and the simple face contact of tire, can double promote joint strength between them, promote the relative wheel hub's of tire location effect, even long-time back tire deformation of using, inflation or ageing, still can keep its effective connection with wheel hub, avoid the emergence of the phenomenon of skidding.
In addition, the structural design that a plurality of low grooves on above motor wheel hub combine the holding surface, its self intensity can not reduce by much, nevertheless can reduce the wheel hub consumptive material, alleviates the component of motor, realizes lightweight design, can improve the control accuracy and the sensitivity of motor to a certain extent.
Drawings
Fig. 1 is a schematic perspective view of a motor according to the present invention;
fig. 2 is a schematic perspective view of the assembled tire of the present invention;
fig. 3 is a partially enlarged schematic view of a portion a in fig. 2 according to the present invention.
Detailed Description
As shown in fig. 1-3, an anti-skid light-weight motor for an intelligent luggage case roller comprises a motor 1 and a tire 2, wherein a hub 11 tightly matched and connected with the tire 2 is arranged on the outer side of the motor 1, a plurality of lower grooves 111 are arranged on the outer circumferential surface of the hub 11 at intervals along the circumferential direction, and a supporting surface 112 is formed on the outer circumferential surface between the adjacent lower grooves 111.
Here, in consideration of the balance of the stress, the size and structure of the lower grooves 111 are the same, and the lower grooves 111 are uniformly distributed at intervals on the outer circumferential surface of the hub 11.
Furthermore, the span of the support surface 112 is greater than the span of the lower groove 111, allowing for an effective supporting connection between the hub 11 and the tyre 2.
The utility model discloses a low groove 111 that sets up on the outer disc of wheel hub 11 and constitute block anti-skidding structure, when the assembly, when the tire 2 that struts contracts, not only form effective close-fitting with wheel hub 11's holding surface 112 and be connected, the place that corresponds low groove 111 simultaneously can further contract inwards and the arch 21 appears in order to form block connection structure, this structure sets up and connected mode, fundamentally has solved the connected mode of current wheel hub and the simple face contact of tire, can double promotion joint strength between them, promote the relative wheel hub 11's of tire 2 location effect, even long-time back tire 2 warp, inflation or ageing, still can keep its effective connection with wheel hub 11, avoid the emergence of the phenomenon of skidding.
In addition, the design of the uniform spacing arrangement of the plurality of lower grooves 111 on the motor hub 11 and the supporting surface 112 does not reduce the strength of the motor hub 11, but reduces the material consumption of the hub 11, reduces the weight of the motor, realizes the light-weight design, and can improve the control accuracy and sensitivity of the motor to a certain extent.
The above, it is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical principles of the present invention to any simple modification, equivalent change or decoration of the above embodiments, still belong to the technical solution of the present invention.
