An edge brush assembly 60 of a sweeping robot according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
As shown in fig. 1 to 4, an edge brush assembly 60 according to an embodiment of the present invention includes: a base 601, bristles 603, and a plurality of mounting feet 602. A plurality of mounting legs 602 are uniformly spaced around the circumference of the base 601, wherein the cross section of the mounting legs 602 perpendicular to the length direction thereof is formed in an axisymmetric shape, and the symmetry axis extends in the vertical direction, and each of the mounting legs 602 may be provided with bristles 603.
Wherein, when the robot of sweeping the floor cleaned ground, brush hair 603 can gather the dust of the robot left and right edge of sweeping the floor to the center round brush and the dust absorption mouth department of the robot of sweeping the floor, at the rotatory in-process of limit brush subassembly 60, the hindrance force that receives can transmit along the normal direction of installation stabilizer blade 602 stress surface when obstacles 608 such as installation stabilizer blade 602 and carpet, pet collide, consequently the deformation direction behind the installation stabilizer blade 602 atress can not directional base 601 bottom, can avoid brush hair 603 in the high-speed rotation because contact in base 601 below and twine the hair or from twining, thereby can solve the problem that limit brush subassembly 60 twines the hair easily.
Therefore, the cross section of the mounting support leg 602 perpendicular to the length direction is formed into an axially symmetric shape, the symmetric axis extends along the vertical direction, the tangential direction of the symmetric plane at two sides of the symmetric axis can deviate from the vertical direction, the deformation direction of the bristles 603 after the mounting support leg 602 is stressed does not point to the bottom of the base 601, and the bristles 603 can be prevented from being entangled or self-entangled due to contact below the base 601 in high-speed rotation, so that the problem that the bristles of the side brush assembly 60 are easily entangled can be solved.
In some embodiments of the present invention, the axisymmetric shape may include a circular shape, and in the rotation process of the side brush assembly 60, when the mounting support 602 collides with the obstacle 608 such as a carpet or a pet, the obstacle 608 contacts with the circular stressed surface, the circular shape is symmetrical about the symmetry axis, the deformation direction of the brush hair 603 can be prevented from pointing to the bottom of the base 601 after the circular stressed surface receives the resistance, and the winding of the brush hair 603 due to the contact below the base 601 or the self-winding can be avoided in the high-speed rotation, so that the winding of the brush hair 603 can be improved.
In some embodiments of the present invention, as shown in fig. 2, the axisymmetric shape may include an isosceles triangle, and the bottom of the isosceles triangle is arranged upward, and when the installation supporting leg 602 collides with the obstacle 608 such as carpet and pet during the rotation of the side brush assembly 60, the obstacle 608 contacts with the inclined force-bearing surface of the isosceles triangle, and the isosceles triangle is symmetric about the symmetry axis, and both the inclined force-bearing surfaces of the isosceles triangle can be prevented from twisting the bristles 603 after being subjected to resistance. Meanwhile, the isosceles triangles are symmetrically arranged, so that the installation supporting feet 602 are not integrally rotated, the installation supporting feet 602 are not distinguished, and can be exchanged randomly without confusion. In addition, the function of improving the twisting of the bristles 603 after the bristles are exchanged is not influenced, the material management cost in the production process is reduced, and the confusion caused by the mismatching of the bristles 603 in the production installation of the sweeping robot or the use process of a user is avoided.
In some embodiments of the present invention, as shown in fig. 3, the axisymmetric shape may include an isosceles trapezoid, and the upper bottom 604 of the isosceles trapezoid is disposed downward, the lower bottom 605 of the isosceles trapezoid is disposed upward, the upper bottom 604 is shorter than the lower bottom 605, in the rotating process of the side brush assembly 60, when the installation supporting leg 602 collides with the carpet or the pet or other obstacles 608, the obstacles 608 contact with the inclined stress surface (i.e., the waist of the isosceles trapezoid) of the isosceles trapezoid, the isosceles trapezoid is symmetric about the symmetry axis, and the two inclined stress surfaces of the isosceles trapezoid receive the resistance and then all prevent the deformation direction of the brush hair 603 from pointing to the bottom of the base 601, so as to further avoid the brush hair 603 from being entangled or self-entangled due to the contact below the base 601 in the high-speed rotation, thereby better improving the entanglement of the brush hair 603. However, the present invention is not limited to this, and the axisymmetric shape can also be set to the shape that has the same function as the isosceles triangle or the isosceles trapezoid.
It should be noted that the cross-sectional shape and size of the mounting leg 602 need not be uniform, and the cross-sectional shape and size of the mounting leg 602 can vary in the range from the base 601 to the free end of the mounting leg 602, depending on whether some portion of the cross-section has a symmetrical inclined surface. Also, due to the improved entanglement of the symmetrical ramp surfaces, the force-bearing surface of the mounting leg 602 may extend straight without being inclined.
In some embodiments of the present invention, as shown in fig. 2 and 3, the mounting leg 602 is recessed downward in an arc shape from the base 601 toward the free end thereof, and when the mounting leg 602 collides with the obstacle 608, the mounting leg 602 is more easily deformed upward, so that the mounting leg 602 is not easily deformed downward, and the bristles 603 are further improved in the course of being entangled or self-entangled, thereby improving the working performance of the edge brush assembly 60.
In some embodiments of the present invention, the upward surface of the installation supporting leg 602 is an arc plane, and the installation supporting leg 602 can be smoothly recessed downward by such a configuration, so as to further prevent the downward deformation of the installation supporting leg 602, thereby better improving the bristle 603 or the self-winding, and further improving the working performance of the edge brush assembly 60.
