Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sweeping robots, in particular to a filamentary elastic roller. Background Art
[0002] With the development of science and technology, more and more families begin to use sweeping robots to clean the floors of their houses, and the drum is an important component of the sweeping robot for cleaning the floor, especially the robot that wipes water stains on the floor. It is used to replace manual cleaning of water stains on the floor. A rag or other wiping cloth is installed on the drum. When the sweeping robot moves, the water stains on the floor are wiped by the rotation of the drum.
[0003] However, the existing roller will reduce the weight of the sweeping robot when it moves. The roller is mostly made of lightweight plastic. This also leads to the roller's rapid rotation and the inertia of the sweeping robot when it encounters hard objects on the ground, which can easily cause collisions and damage the roller itself. Utility Model Content
[0004] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a filamentary elastic roller.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a filamentary elastic roller is designed, comprising a support shaft, a cylinder is coaxially arranged on the support shaft, a plurality of strip plates arranged at intervals are arranged on the outer side of the cylinder, and the cross section of the strip plates is an arc surface corresponding to the coaxial axis of the cylinder, a plurality of arc rods arranged at intervals and having elasticity are installed on one side of the strip plates close to the cylinder, and the bottom of the arc rods is fixed on the cylinder;
[0006] A sleeve is sleeved on the cylinder, the inner wall of the sleeve is gap-matched with the strip plate, and a wiping cloth for wiping water stains is installed on the outer wall of the sleeve.
[0007] Preferably, a plurality of connecting rods are installed on the inner wall of the cylinder, the connecting rods are cross-shaped and tilted, and the other ends of the connecting rods are fixed on the supporting shaft.
[0008] Preferably, transmission shafts for connecting to the motor are connected to both ends of the support shaft.
[0009] Preferably, the sleeve is an annular elastic rubber plate.
[0010] Preferably, the end of each strip plate is connected to an arc-shaped plate bent toward the cylinder.
[0011] Preferably, an annular plate is provided at the end of the cylinder, the annular plate is sleeved on the supporting shaft, and the edge of the annular plate corresponds to the end of the sleeve, a sealing ring corresponding to the end of the sleeve is installed on the side of the annular plate close to the sleeve, and an annular seat is also installed on the side of the annular plate close to the cylinder, and the annular seat is threadedly connected to the outer wall and the inner wall of the cylinder.
[0012] The design scheme proposed by the utility model has the following beneficial effects during application:
[0013] 1. The filamentary elastic roller supports the sleeve through the elastic arc rod, which buffers the bumps and collisions on the sleeve surface and protects the roller.
[0014] 2. The filamentary elastic roller is connected to a plurality of arc rods through a strip plate. When the sleeve is locally stressed, the arc rod undergoes the necessary elastic deformation, and the strip plate can distribute the local stress of the sleeve to the plurality of arc rods, thereby reducing the stress intensity of each arc rod to prevent the reaction force of the arc rod from acting on the cylinder and causing damage to it, thereby further improving the protection effect of the roller.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-Figure 4 A filamentary elastic roller comprises a support shaft 1, and transmission shafts 9 for connecting to a motor are connected to both ends of the support shaft 1. After the roller is placed in a sweeping robot, the transmission shaft 9 can be connected to the motor in the sweeping robot, so that the roller can rotate when the sweeping robot moves;
[0022] like Figure 1 and Figure 2 As shown, a cylinder 2 is coaxially arranged on the support shaft 1. In actual use, the cylinder 2 is a plastic cylinder. In order to further reduce the weight of the drum, a plurality of connecting rods 3 are installed on the inner wall of the cylinder 2. The connecting rods 3 are cross-shaped and inclined, and the other ends of the connecting rods 3 are fixed on the support shaft 1. While ensuring that the support shaft 1 supports the cylinder 2 well, the drum is designed to be lightweight.
[0023] like Figure 2 and Figure 3 As shown, a plurality of spaced strip plates 5 are provided on the outer side of the cylinder 2, and the cross section of the strip plates 5 is an arc surface coaxial with the cylinder 2. A plurality of spaced and elastic arc rods 4 are installed on the side of the strip plates 5 close to the cylinder 2, and the bottom of the arc rods 4 is fixed on the cylinder 2. The plurality of arc rods 4 provide support for the same strip plate 5. When the strip plate 5 is subjected to force, the plurality of arc rods 4 act simultaneously, so that the force on the strip plate 5 is dispersed, which helps to improve the buffering effect. Figure 4 As shown, a sleeve 7 is sleeved on the cylinder 2, the inner wall of the sleeve 7 is gap-matched with the strip plate 5, and a rag 8 for wiping water stains is installed on the outer wall of the sleeve 7. In actual use, the arc rod 4 is an elastic rubber rod or an elastic metal rod, and a plurality of arc rods 4 form an elastic filamentary structure between the sleeve 7 and the cylinder 2. While supporting the sleeve 7, it buffers the force on the sleeve 7 through its own elastic deformation, thereby protecting the drum.
[0024] In order to ensure the stability of the sleeve 7 after installation, Figure 4 As shown, an annular plate 10 is provided at the end of the cylinder 2, and the annular plate 10 is sleeved on the supporting shaft 1, and the edge of the annular plate 10 corresponds to the end of the sleeve 7, and a sealing ring corresponding to the end of the sleeve 7 is installed on the side of the annular plate 10 close to the sleeve 7, and an annular seat 11 is also installed on the side of the annular plate 10 close to the cylinder 2, and the annular seat 11 is threadedly connected to the outer wall and the inner wall of the cylinder 2, which limits the end of the sleeve 7 to prevent the sleeve 7 from shifting when wiping water stains, and the installation of the annular plate 10 will block the gap between the cylinder 2 and the sleeve 7 to prevent water or debris from entering between the cylinder 2 and the sleeve 7, which is difficult to clean and easily affects the normal deformation of the arc rod 4.
[0025] Specifically, when in use, after the sleeve 7 is put on the strip plate 5, the annular plate 10 is taken and rotatably installed on the end of the cylinder 2 to fix the sleeve 7, and then the cylinder is installed in the sweeping robot. When the sweeping robot moves, it will drive the rag 8 to contact the ground, and the support shaft 1 will drive the rag 8 to rotate under the action of the motor, so as to wipe the water stains on the ground. Once the sleeve 7 collides with an external object, the force generated by the collision will be transmitted by the sleeve 7 to the strip plate 5 and then to the arc rod 4. At this time, the arc rod 4 will be deformed due to the force and react back to the sleeve 7, so that the collision force is consumed in the deformation process of the arc rod 4, thereby buffering the force on the sleeve 7.
[0026] In order to improve the force buffering effect of the sleeve 7, the sleeve 7 is an annular elastic rubber plate. In actual use, the inner diameter of the sleeve 7 is smaller than the outer diameter of the strip plate 5. When the sleeve 7 is sleeved on the strip plate 5, the sleeve 7 can obtain a force along the radial direction of the sleeve 7 under its own elasticity and the elasticity of the arc rod 4, thereby improving the fastening effect of the sleeve 7 on the strip plate 5, and the elastic effect of the sleeve 7 can further improve the buffering effect of the roller when subjected to external force.
[0027] It should be further explained that, in order to facilitate the installation of the sleeve 7 on the strip plate 5, the end of each strip plate 5 is connected to an arc-shaped plate 6 bent toward the cylinder 2, so that the outer diameter of the end of the strip plate 5 is smaller than the inner diameter of the sleeve 7, thereby facilitating the sleeve 7 to be put on the strip plate 5 from the end of the cylinder 2.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
