Description

Rear wheel deceleration adjustment mechanism for mobile vehicle

This invention is about a mobile vehicle rear wheel deceleration adjustment mechanism, and in particular, refers to an innovative designer of a mobile vehicle rear wheel deceleration adjustment mechanism that utilizes friction resistance to slow down the wheel rotation speed, thereby achieving the effect of decelerating the wheel, so as to make the human-propelled mobile vehicle safer when in use, and to increase the practicality of its overall implementation and use.

It is common to see people suffering from lower body paralysis due to major diseases or injuries such as car accidents and strokes, or long-term bedridden illness, which causes the muscles in both legs to atrophy and make it impossible for them to stand up and walk easily. In addition, as the elderly grow older, their body functions deteriorate and they are unable to perform many movements smoothly, especially walking. The muscles, joints and bones of the legs cannot support the body for a long time, so walking is not smooth. When these people with mobility problems want to maintain smooth walking and rehabilitation, they often use mobile vehicles such as wheelchairs, strollers or rollators to help alleviate the force on their legs when walking, allowing them to move longer distances.

However, although the above-mentioned wheelchairs, strollers or rollators can achieve the expected effect of assisting people with limited mobility to walk conveniently, it is also found in their actual operation and use that the resistance of the wheels of such mobile vehicles cannot be controlled when they are pushed by the public. As a result, people who walk slowly are very likely to fall down due to the fast movement of the mobile vehicle and their steps cannot keep up with the speed of the mobile vehicle. This causes safety concerns in the use of the mobile vehicle, and there is still room for improvement in its overall structural design.

Therefore, the creator, in view of this, adheres to the rich design development and actual production experience of the relevant industry for many years, further studies and improves the existing technical means, and provides a mobile vehicle rear wheel deceleration adjustment mechanism, in order to achieve the purpose of better practical value.

The main purpose of this invention is to provide a rear wheel deceleration adjustment mechanism for a mobile vehicle, which mainly utilizes a pressure wheel to compress the wheel to generate friction resistance, so as to slow down the rotation speed of the wheel, thereby achieving the effect of decelerating the wheel, so as to make the human-propelled mobile vehicle safer when in use, and to increase the practicality and effectiveness characteristics in its overall implementation and use.
