Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It clearly and completely describes, it is clear that described embodiment is only the utility model one embodiment, and and not all reality Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work The every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figures 1 to 4, the present embodiment includes protective cover 101, mounting base 102, takes turns 103, axle sleeve 105 and pin shaft 106, Wherein 101 appearance of protective cover is equipped with installation buckle 1011, and rotation orifice 1021 is equipped in mounting base 102 can opposite mounting base 102 Independent rotational movement is done, the rotation orifice 1021 is to be limited at the annular element for being only capable of making rotating motion in mounting base 102, peace The driving structures such as motor, gear (not shown) is additionally provided in dress seat 102 and rotation orifice 1021 is mechanically coupled makes its rotation Movement, pin shaft 106 include free end 1061 and assembling end 1062, and assembling 1062 terminal position of end is equipped with screw thread.Mounting base 102 from Protective cover 101 is internally extended to play the role of support and installation wheel 103, and 103 centers of wheel are equipped with through-hole 1031, axle sleeve 105 cross sectional shape inner wall is annulus, and the centre of axle sleeve 105, which is run through, is equipped with axle sleeve hole 1051, and fixing card connects 1031 He of hole Rotation orifice 1021,1062 outer surface of assembling end of pin shaft 106 are equipped with screw thread, and the fixed part inner wall of mounting base 102 is equipped with spiral shell Line is so that the assembling end 1062 of pin shaft 106 can screw in realization fastening assembling.

The more specific assembling mode of the present embodiment is that wheel 103 is placed in the accommodating space of protective cover 101 and makes through-hole 1031 are aligned with rotation orifice 1021, are inserted into the axle sleeve hole 1051 of axle sleeve 105 towards 102 direction of mounting base along through-hole 1031, due to The clamping effect of axle sleeve 105 can make wheel 103 keep synchronous rotation status with mounting base 102, along through-hole 1031 towards mounting base 102 The assembling end 1062 of pin shaft 106 is inserted into direction and screw thread and the screw thread of 102 fixed part of mounting base setting are fitted close, after The utility model is integrally packed into the driving wheel installation site of intelligent mobile robot.At this point, wheel 103, axle sleeve 105 and rotating hole Part 1021 keeps identical rotation status, and axle sleeve 105 is limited to rotary motion by pin shaft 106.It can be it can be clearly seen that originally in Fig. 4 Implementation described in utility model, since axle sleeve 105 is clamped rotation orifice 1021 and through-hole 1031 so that mounting base 102 with Wheel 103 is able to maintain identical rotary motion state；It is fixedly connected in mounting base 102 due to pin shaft 106 and is kept with axle sleeve 105 Relative rotary motion, so that wheel 103 can steadily make rotating motion.

The specific implementation of the present embodiment is that the driving structure in mounting base 102 drives rotation under controller action, Driving force is transmitted at rotation orifice 1021 by mechanical connection manner, so that axle sleeve 105 also follows it to make rotating motion, simultaneously Wheel 103 also does corresponding rotary motion under the effect of axle sleeve 105；Wherein, since the assembling end 1062 of pin shaft 106 is connected through a screw thread Because without making rotating motion in the fixed part of mounting base 102, and it can only play support, restriction effect.It is needing to be split Except when, it is only necessary to pin shaft 106 is screwed out from the screw thread of mounting base 102, by pin shaft 106, axle sleeve 105, wheel 103 and mounting base 102 separation, which disassemble, to be come.

In another embodiment, 1062 cross sectional shape of assembling end of pin shaft 106 can be circle or other shapes, as long as It can guarantee that axle sleeve 105 can be rotated around pin shaft 106.

In another embodiment, the cross section of the free end 1061 of pin shaft 106 is greater than axle sleeve hole 1051 and through-hole 1031 It is only rotated with limiting wheel 103.

In another embodiment, axle sleeve hole 1051 can be circle or other shapes, as long as can guarantee that axle sleeve 105 can be around 106 rotary motion of pin shaft.

In another embodiment, wheel 103 is that recessed groove makes axle sleeve 105 in through-hole 1031 and assembling 1062 contact position of end Preferably being fixed in wheel increases aesthetic measure.

In another embodiment, axle sleeve 105 is equipped with axle sleeve holder 1052 in end with abundant clamping wheel 103, is setting It can be clamped in recessed groove in the case where having recessed groove, the shape of the axle sleeve holder 1052 does not limit.

In another embodiment, the shape of the through-hole 1031 and rotation orifice 1021 is not limited to circle, as long as right It answers axle sleeve 105 that can correspond to be fixedly connected, said two devices is made not make rotating motion with respect to axle sleeve 105.

It should be noted that disclosed embodiment is only the utility model specific embodiment, it is for clear explanation The citing of the utility model, and be not to be construed as limiting the scope of the utility model, certainly this reality can not be limited with this With novel scope of the claims, to those skilled in the art, equivalent change made according to the claim of the utility model Change, modify, change etc., it still falls within the scope of the utility model, the claim that should be included in the utility model is protected In range.
