The content of the invention
Technical problem to be solved in the utility model is to provide a kind of any place, damping effect of being applied to and greatly increases
Sweeping robot damping buffer device.
The utility model is achieved through the following technical solutions:A kind of damping buffer device of sweeping robot, bag
Sweeping robot is included, and for the universal wheel of walking, the universal wheel has its independent vibration absorber, the vibration damping dress
Two elastic rings including being wrapped on universal wheel are put, elastic ring is snapped into the mounting groove that universal hub cap is set, elastic ring
Centre has a lock chamber, and the both sides of universal wheel are respectively provided with a cavity, a mobilizable end cap is respectively mounted in cavity, holds
Lid is just set to cavity, and end cap can be entered into the lock chamber of elastic ring and eject elastic ring when pressing inward against end cap
Universal wheel, around a shock-damping structure is set on each end cap, elastic ring is contacted with shock-damping structure after end cap is snapped in lock chamber.
Used as preferred technical scheme, the medial surface of the elastic ring is provided with yielding chamber, makes a concession the internal diameter in chamber equal to recessed
The internal diameter in chamber.
Used as preferred technical scheme, the shock-damping structure includes a shock absorbing ring, and shock absorbing ring is wrapped in the setting of end cap outer wall
Draw-in groove in, be provided with more than one group of spring in draw-in groove, shock absorbing ring wraps up more than one spring, shock absorbing ring lateral surface and end
Outer side of lid face is concordant.
Used as preferred technical scheme, the shock absorbing ring is made of elastomeric material.
Used as preferred technical scheme, the medial surface of the end cap is provided with arc section.
As preferred technical scheme, the internal diameter of the external diameter more than lock chamber in the middle of elastic ring of the end cap.
The beneficial effects of the utility model are:The utility model simple structure, when unstable section is run into, can be by elasticity
Coil is ejected, and increases the height of universal wheel, that is, increase the height of robot bottom surface and ground, and with its independent damping system
System so that more steady when using, is applicable to multiple occasions.
Specific embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including sweeping robot, and for the universal wheel 2 of walking, the universal wheel 2 has its only
Vertical vibration absorber, the vibration absorber is wrapped in two elastic rings 3 on universal wheel 2, and elastic ring 3 snaps into universal wheel
In the mounting groove that shell is set, there is a lock chamber 6 in the middle of elastic ring 3, the both sides of universal wheel 2 are respectively provided with a cavity, recessed
A mobilizable end cap 8 is respectively mounted in chamber, end cap 8 is just set to cavity, and end cap can enter when pressing inward against end cap 8
Universal wheel is ejected in the lock chamber of elastic ring and by elastic ring 3, around one shock-damping structure of setting, end cap card on each end cap
Elastic ring is contacted with shock-damping structure after entering in lock chamber.
In the present embodiment, the medial surface of elastic ring 3 is provided with yielding chamber 7, and the internal diameter for making a concession chamber 7 is equal to the internal diameter of cavity,
Shock-damping structure includes a shock absorbing ring 1, and shock absorbing ring 1 is wrapped in the draw-in groove of end cap outer wall setting, and more than one group is provided with draw-in groove
Spring 5, shock absorbing ring 1 wraps up more than one spring 5, and shock absorbing ring lateral surface is concordant with end cap lateral surface.
Wherein, shock absorbing ring 1 is made of elastomeric material, therefore shock absorbing ring 1 is deformable, and elastic ring can be coordinated to use.
In the present embodiment, the medial surface of end cap is provided with arc section 4, and when end cap is inwardly extruded, end cap can be smoothly
In snapping onto the lock chamber 6 of elastic ring 3 by arc section 4, and with continuing to snap in, end cap bottom can smoothly enter into yielding
In chamber.
In the present embodiment, the external diameter of end cap 8 more than the middle lock chamber 6 of elastic ring 3 internal diameter, why by the external diameter of end cap
The internal diameter more than lock chamber is designed to, because, when end cap is extruded to lock chamber, end cap can be extruded to outer elastic ring
Portion, as shown in Fig. 2 now end cap medial extremity is entered into yielding chamber, and the shock-damping structure that end cap outside is set connects with elastic ring
Touch.
After elastic ring is extruded, the height of its universal wheel is to increase, therefore when elastic ring runs into the stone of projection, now bullet
Property circle deformation, and building circle contact with elastic ring is also therefore compressive deformation, and at the same time, spring is also pressurized, and realizes damping.
Further, since sweeping robot has carried a shock mitigation system, therefore by after damping twice, it can more put down
Steady operation.
The beneficial effects of the utility model are:The utility model simple structure, when unstable section is run into, can be by elasticity
Coil is ejected, and increases the height of universal wheel, that is, increase the height of robot bottom surface and ground, and with its independent damping system
System so that more steady when using, is applicable to multiple occasions.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
