As another example, as shown in figure 4, elastic component mounting portion 50 is arranged on the upper surface of cover portion 23 namely bullet
Property part 5 is arranged between the upper surface of cover portion 23 and the top surface of drive wheel bracket 3.
The assembling process of drive wheel assemblies 100 provided in this embodiment is first to install driving mechanism 6 and transmission mechanism
In shell 2 on corresponding mounting portion, then assembly is fixed by transmission shaft 26 and transmission mechanism in wheel 1, then elastic
Part 5 is through the elastic component mounting portion 50 on shell 2 together with 2 direct-assembling of shell, and the quasi- finished product of drive wheel assemblies assembles at this time
It completes, as shown in Figure 3；The subsequent quasi- finished product of drive wheel assemblies is fitted together by rotation axis 7 with drive wheel bracket 3, finally again
It is whole to be assembled with bracket cover 4, it is completed to this entire drive wheel assemblies 100.It can be seen that elastic component 5 can be very easy
It is fitted together with shell 2, simplifies the process of driving wheel later period assembling, improve assembly efficiency, reduce assembly cost.
Principle of the drive wheel assemblies 100 provided in this embodiment from main regulation height are as follows: due to shell 2 and the driving wheel
Bracket 3 is pivotally connected to, and is provided with elastic component between the top surface of top surface and the shell 2 in the drive wheel bracket 3
5, therefore, the shell 2 can the relatively described drive wheel bracket 3 be rotated up so that the shell 2 and described under external force
Drive wheel bracket 3 is close to each other, to reduce the height of the drive wheel assemblies 100；The elastic component 5 can be to the shell 2
Apply active force (such as with the external force opposite effect power), to make 2 phase of shell when the external force reduces or disappears
The drive wheel bracket 3 is rotated down, to make the shell 2 and the drive wheel bracket 3 be located remotely from each other and increase described
The height of drive wheel assemblies 100.Fig. 4 is shown when not having external force, under the action of elastic component 5, wheel 1 (namely shell
2) opposite drive wheel bracket 3 rotates down the status diagram so that when the height of drive wheel assemblies 100 reaches maximum height H1.
Fig. 5 is shown by external force, and wheel 1 (namely shell 2) is rotated up with respect to drive wheel bracket 3 so that elastic component 5 is in
Most compressed state, the height of drive wheel assemblies 100 reach status diagram when minimum constructive height H2.With drive wheel assemblies
The height of the variation of external force suffered by 100, drive wheel assemblies 100 can be adjusted automatically between Fig. 4 and height H1 and H2 shown in fig. 5
Section, wherein the precision and dynamics of H1, H2 and automatic adjustment can be configured by the size, precision and dynamics of elastic component 5.
Drive wheel assemblies according to the present utility model, the process for simplifying the assembling of driving wheel later period improve assembly efficiency, drop
Low assembly cost；Also, drive wheel assemblies from main regulation height function are realized by elastic component, which has height
The characteristics of reliability, high life, it is ensured that the global reliability of drive wheel assemblies, while the dynamics of elastic component and accurate size can
Tune also can guarantee dynamics and accuracy of the driving wheel from main regulation height；Finally, the rotation of the drive wheel assemblies of the utility model
Axis is arranged close to the center of driving wheel rent, therefore can suitably reduce entire component in the occupied space of short transverse.
In another embodiment, the utility model also provides a kind of intelligence including the drive wheel assemblies in previous embodiment
It can be from mobile device, wherein the intelligence can be arbitrary the device for needing to be equipped with drive wheel assemblies from mobile device, including
But be not limited to sweeping robot, intelligent robot etc..Intelligence from mobile device can also include one, two or more
The drive wheel assemblies, what it is due to the utility model includes intelligently drive wheel assemblies above-mentioned from mobile device, same
Have the advantages that the above-mentioned of drive wheel assemblies.
When the drive wheel assemblies 100 of the utility model are applied to intelligence from mobile device, as shown in fig. 6, in intelligence
When putting it on the ground from the host of mobile device, wheel 1 is set largely to contract by gravity (namely wheel body effect of being under pressure)
Enter in fuselage, elastic component 5 is compressed at this time, the extended line of the line between the axle center of rotation axis 7 and the axle center of wheel 1 and driving
Angle between the top surface of wheel support 3 is A, and the size that angle reaction wheel 1 exposes outside fuselage (can also react wheel 1
From the height after main regulation), the angle is bigger, and height is bigger；Floor surface is encountered from mobile device motion process in intelligence
When out-of-flatness, such as when encountering pit, it is equivalent to external force and reduces or disappear elastic component 5 at this time and apply substantially downward pressure to shell
Power rotates down shell 2 around rotation axis 7, to make the wheel 1 being mounted on shell 2 under the action of elastic component 5 from fuselage
From inside to outside/move downward, the height of wheel 1 is automatically adjusted, elastic component 5 as shown in Figure 5 restores, and wheel 1 is located at machine
Size outside body reaches maximum, the extended line and drive wheel bracket 3 of the line between the axle center of rotation axis 7 and the axle center of wheel 1
Top surface between angle be B, the angle of the included angle B is greater than the angle of included angle A, intelligence from mobile device in moving process,
Angle be in changes between A and B, even if the case where encountering ground out-of-flatness drive wheel assemblies set can from main regulation height,
Guarantee even running, and the obstacle climbing ability with certain altitude.
Also, the position of the rotation axis 7 of the utility model driving wheel structure is mobile (namely up moving) toward component center,
For example, the position of rotation axis 7 is located at the middle part or middle part of entire 2 height of shell or more, this setup compares shaft position
The case where setting in bottom, shell 2 move down out intelligence from the fuselage of mobile device with wheel 1 or are forced upward into fuselage
When, since the position of rotation axis 7 is high, it can suitably reduce entire drive wheel assemblies in the occupied space of short transverse, more
Into one, can be the intelligence including the drive wheel assemblies from the fuselage of mobile device the occupied space of short transverse more
It is small.
