Problems solved by technology

However, the flexible material itself is prone to deformation and shaking, and it is difficult to transmit friction to the entire body
[0004] In order to solve the problem that the robot cannot work normally due to insufficient friction generated by the suction cup, the prior art adopts a technical solution to reduce the weight of the robot or increase the number of suction cups
Although reducing the weight of the robot or increasing the number of suction cups can solve the above problems to a certain extent, the weight reduction of the robot is often accompanied by the loss of some functions (such as omitting some parts) or a substantial increase in production costs (such as using weight Alternative materials that are light, strong, and expensive), and the increase in the number of suction cups will lead to a more complex structure of the robot, and may even affect the walking of the robot and increase the energy consumption of the robot due to excessive friction

Embodiment 1

[0033] Such as figure 2 As shown, a suction cup capable of increasing friction includes a suction cup body 3 and a friction pad 301 , and the friction pad 301 is fixedly arranged on the top of the inner cavity of the suction cup body 3 .

[0034] When using the suction cup of the present invention which can increase the friction force on the robot, the suction cup body 3 can be installed on the machine base 5 at the bottom of the robot.

[0035] figure 2 What is shown is the structure of this embodiment in the non-suction state. At this time, the suction cup body 3 is in the suction state, and the friction pad 301 is separated from the working surface 4 .

[0036] Such as image 3 As shown, when the robot needs the suction cup which can increase the friction force of the present invention to provide greater friction, the suction cup body 3 deflates (that is, vacuums the suction cup body 3), the pressure in its inner cavity decreases, and the difference in internal and exte...

[0039] Such as Figure 4 As shown, it is a robot with a steering function. A rotating mechanism is provided at the bottom of the robot. The rotating mechanism includes a large gear 303, a pinion (not shown) meshing with the large gear 303, and a driving mechanism for driving the pinion ( Not shown in the figure), the small gear is fixedly connected with the body, the large gear 303 is fixedly connected with the suction cup, the large gear 303 is connected with the body through bearings and realizes relative rotation, the large gear 303 is fixed with the outer ring of the bearing, and the small gear is fixed with the inner ring of the bearing , when the body rotates, the large gear 303 and the suction cup are adsorbed on the working surface, and the driving mechanism drives the pinion to rotate around the large gear 303, which realizes the rotation of the body. Due to the large friction force required during rotation, the friction force generated by the negative pressure of the...

Abstract

A suction cup capable of increasing friction and a suction-type auto-moving apparatus. The suction cup comprises a suction cup body (3), and further comprises frictional pads (301, 302). The frictional pads (301, 302) may be tightly pressed to a working surface with the release of air of the suction cup, thereby increasing friction between the suction cup and the working surface. A beneficial effect is that: When a robot needs large friction, the frictional pads (301, 302) are tightly pressed to the working surface, thereby increasing friction between the suction cup and the working surface. When the robot does not need very large friction, the frictional pads (301, 302) leave the working surface, thereby reducing friction between the suction cup and the working surface.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a suction cup and an adsorption self-moving device capable of increasing friction. Background technique [0002] A robot working on an upright or inclined working surface (also known as a working surface) mainly relies on the adsorption force and friction generated by the suction cup to maintain its work. In the case of insufficient friction force generated by the suction cup, the robot cannot work normally, and in the case of excessive friction force, it is not conducive to the walking of the robot, and will greatly increase the energy consumption of the robot. Therefore, the robot has quite high requirements on the magnitude of the friction force generated by the suction cup, and the split wall cleaning robot is even more so. [0003] Usually, the split-type wall cleaning robot realizes the walking of the whole robot on the working surface through the suction cups arranged on t...
