Problems solved by technology

[0004] In view of this, the object of the present invention is to propose a foot anti-slip device with controllable friction force, and apply magnetorheological rubber material to the anti-slip occasion of the foot to adapt to the situation that the friction performance of the friction part needs to be continuously adjusted, so as to avoid the present situation. There is a problem that the friction coefficient is fixed and cannot be adjusted in the foot anti-slip situation

Embodiment 1

[0030] As shown in the figure, the friction controllable shoe sole 1 of the present embodiment is characterized in that: a foot anti-skid device 2 with controllable friction force is arranged on the bottom surface of the shoe sole 1, which includes magnetorheological rubber The formed anti-slip layer 3 and the variable magnetic field that can generate magnetic force on the anti-slip layer 3 are arranged between the anti-slip layer 3 and the sole 1. The thickness of the magnetorheological rubber in this embodiment is 1-3mm, which can achieve better use effect The variable magnetic field of the present embodiment includes a coil holder 4, an excitation coil 5 wound on the coil holder 4 and a controllable power supply 6 communicated with the excitation coil 5, the anti-slip layer 3 matches the shape of the sole 1, and can The entire surface of the sole 1 acts to improve the anti-slip effect of the shoe to the greatest extent.

[0031] Further, the coil fixing seat 4 is provided w...

Embodiment 2

[0035] like figure 2 As shown, different from the first embodiment, this embodiment is provided with a friction-controllable foot anti-skid device 2 on the top surface of the sole, so that it forms a variable friction contact with the insole, thereby enhancing both sides. The binding force between them achieves a stronger fixing effect, prevents the sliding between the athlete's sole and the insole, and makes the athlete's sole fix better, which is conducive to strenuous exercise and improves sports performance.

Embodiment 3

[0037] like image 3 As shown, the difference from the first embodiment is that the bottom surface and the top surface of the sole are provided with a foot anti-skid device 2 with controllable friction, so that the friction can be adjusted on the bottom surface and the top surface of the sole. , so as to achieve better anti-skid effect.

[0038] Application 2: A friction-controllable insole

[0039] Embodiment one:

[0040] like Figure 4 As shown, a friction-controllable insole in this embodiment is the same as the above-mentioned friction-controllable sole, and is characterized in that: a friction-controllable foot anti-skid device is provided on the bottom surface of the insole 8, which includes The anti-slip layer made of magnetorheological rubber and the variable magnetic field that can produce magnetic effect on the anti-slip layer between the anti-slip layer and the sole are arranged. The thickness of the magnetorheological rubber material of the present embodiment i...

Abstract

The invention discloses a friction-controllable foot anti-skid device, and belongs to the anti-skid technical field. The foot anti-skid device comprises an anti-skid layer made of magnetorheological rubber and a variable magnetic field of which magnetic lines penetrate through the anti-skid layer and enable a magnetorheological effect to appear, and the variable magnetic field comprises a magnet exciting coil and a controllable power source connected with the magnet exciting coil. According to the friction-controllable foot anti-skid device, under the action of the variable magnetic field, the friction coefficient of foot contact portions can be changed, therefore, the adhesion level is improved, all foot movement bodies such as a shoe sole, a foot pad and a robot palm and sole have a good anti-skid effect, and the foot anti-skid device is beneficial for reducing the sports load of an athlete and the risk of accidents and improving achievement of the athlete in competition; meanwhile, the working stability and working precision of a robot can be promoted, and rapid development of related industries such as competitive sports and robots can be promoted to some extent.

Description

technical field [0001] The invention belongs to the technical field of anti-skid, and relates to a foot anti-skid device with controllable frictional force. Background technique [0002] Rubber materials are widely used in the production and life of the people, which brings great convenience to everyone. Many of them are used to increase friction. The soles, foot pads, and robot hands and feet made of rubber have good anti-skid effect, but this anti-skid effect is single. Once it is made, its friction performance is fixed, and its friction performance cannot be changed according to different situations, which restricts some The development of special industries such as competitive sports and robotics. [0003] Although magnetorheological materials have been widely used in production and life. Because it can change the stiffness and damping of materials through a variable magnetic field, it is widely used in the field of vibration reduction and vibration isolation, but has...
