Problems solved by technology

[0003] Since the driving wheel is pressed to the ground by the tension or pressure of the spring, when the driving wheel passes the uneven road surface, if the ground is relatively low, as the tire descends, the pressure of the spring will decrease, and the contact between the wheel and the ground will decrease. The friction force will also be reduced, and the driving ability will be weakened, which will make the robot unable to move forward

[0039] Please refer to Figure 1 to Figure 3 , the present embodiment provides a suspension mechanism 100, which can convert the pressure or tension generated by the elastic member into the ground pressure on the driving wheel, which increases the grip force of the driving wheel when moving on uneven roads , to ensure its smooth operation.

[0040] The suspension mechanism 100 includes: a housing 110 , an elastic member 120 , a first swing arm 130 , a pulley 140 , a second swing arm 150 , a rotating shaft 160 , a driving wheel 170 , a motor 180 and a connecting piece.

[0041] In an optional implementation manner, the above-mentioned connecting member includes: a flange 190 and bolts.

[0042] One end of the elastic member 120 is connected to the housing 110 , and the other end of the elastic member 120 is movably connected to one end of the first swing arm 130 .

[0043] Specifically, the elastic member 120 is connected to one end of the housing 110 through the fixing rod 1...

[0089] Such as Figure 8 As shown, this embodiment provides a mobile robot 200, which has better obstacle-surmounting ability and can smoothly pass over ridges and gaps. It includes a robot body 210 and the aforementioned suspension mechanism 100 , and the robot body 210 is installed on the casing 110 of the suspension mechanism 100 .

[0090] It should be noted that the mobile robot 200 provided in this embodiment includes at least two groups of the suspension mechanisms 100 described in the first embodiment, so as to satisfy the condition that the mobile robot 200 can be balanced.

[0091] The suspension mechanism 100 is an integral structure, and the robot body 210 can be directly installed on the suspension mechanism 100 through bolts installed on the housing 110 .

[0092] Further, the robot body 210 uses four universal wheels 211 as shown in the figure as driven wheels, the drive wheel 170 provides power, and the four universal wheels 211 start to move due to friction. ...

Abstract

The invention provides a suspension mechanism, which has better obstacle-surmounting capability. The suspension mechanism comprises a housing, an elastic member, a first swing arm, a pulley, a secondswing arm, a rotating shaft, a driving wheel, a motor and a connecting member. One end of the elastic member is connected with the housing, and the other end of the elastic member is movably connectedwith one end of the first swing arm. The other end of the first swing arm is connected with the pulley, and the pulley is in rolling contact with a side edge of the second swing arm; The second swingarm is movably connected with the housing through the rotating shaft, and the second swing arm is rotatable about the rotating shaft; The motor is connected with the second swing arm through a connecting piece. The invention also provides a mobile robot, which comprises a robot body and the suspension mechanism. The mobile robot can smoothly run on the uneven road surface, and has better sill andseam crossing ability.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to a suspension mechanism and a mobile robot. Background technique [0002] Nowadays, the application of mobile robots is more and more extensive, and the requirements for the stability of mobile robots are getting higher and higher. Most of the existing mobile robots have a swing arm suspension structure. The motor and the driving wheel are fixed on a swing arm, and one end of the swing arm can rotate around the shaft. Ground, ensure that the driving wheel is always in contact with the ground, and ensure the friction between the driving wheel and the ground. [0003] Since the driving wheel is pressed to the ground by the tension or pressure of the spring, when the driving wheel passes the uneven road surface, if the ground is relatively low, as the tire descends, the pressure of the spring will decrease, and the contact between the wheel and the ground will decrease. The f...
