A small suspension steering structure

Abstract

The invention discloses a small suspension type steering structure. The steering structure comprises a vertical pipe; a supporting frame is fixedly arranged at the position, close to the bottom end, of the outer surface of the vertical pipe; a butt joint cylinder is welded to the outer surface of each of the two sides of the supporting frame; a guide rod is fixedly arranged on the inner surface ofeach butt joint cylinder; and the outer surfaces of the guide rods are sleeved with guide cylinders. According to the small suspension type steering structure, during the movement of the guide rods,a resistor connected into a circuit is constantly changed, the current flowing through the resistor is also continuously changed, so that the depth by which the guide rods are inserted into the guidecylinders can be detected by observing the magnitude of the current, the internal pressure of the guide cylinders can be conveniently adjusted in time and whether the guide cylinders are damaged or not can be conveniently detected in time, an extrusion plate is movably arranged at the bottom end of a connecting frame through a spring, so that whether a wheel is deformed or not and whether debris exists on the surface of the wheel or not can be detected, and secondly, a clearing brush adheres to the bottom end of the extrusion plate, so that the debris on the surface of the wheel can be cleared.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a small suspension type steering structure. Background technique [0002] The position of the front wheel of the bicycle is equipped with a small suspension steering structure, also known as the bicycle front fork, which can not only control the steering of the front wheel, but also have a good shock absorption effect. The requirements for the front fork are getting higher and higher, resulting in the traditional bicycle front fork can no longer meet people's needs; [0003] At present, when the bicycle front fork is in use, a certain amount of air is stored between the guide rod and the guide cylinder. When the guide rod moves to the inside of the guide cylinder, the air is compressed, and the internal pressure increases, preventing the guide rod from continuing to move downward. So as to achieve the effect of shock absorption, the more air is stored between the guide rod and the guide ...

Problems solved by technology

[0002] The position of the front wheel of the bicycle is equipped with a small suspension steering structure, also known as the bicycle front fork, which can not only control the steering of the front wheel, but also have a good shock absorption effect. The requirements for the front fork are getting higher and higher, resulting in the traditional bicycle front fork can no longer meet people's needs;

[0003] At present, when the bicycle front fork is in use, a certain amount of air is stored between the guide rod and the guide cylinder. When the guide rod moves to the inside of the guide cylinder, the air is compressed, and the internal pressure increases, preventing the guide rod from continuing to move downward. So as to achieve the effect of shock absorption, the more air is stored between the guide rod and the guide cylinder, the smaller the range of movement of the guide rod inside the guide cylinder, when it is impacted, the force that can be relieved is reduced, and most of the impact force is transmitted For the user, if there is less air stored between the guide rod and the guide cylinder, the range of motion of the guide rod inside the guide cylinder will become larger, and it will easily shake violently when it is impacted

[0004] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventors of the present application found that the above-mentioned technology has at least the following technical problems: (1), due to the adjustment between the guide rod and the guide cylinder, the user's personal subjective experience is required. Adjustment, so the user not only needs to perform multiple adjustments, but also adjustment deviations are prone to occur at the same time, which affects the safety of the bicycle front fork; The part that is vulnerable to impact, so the wheel is most likely to be deformed, and the detection of the deformation of the wheel can only be judged by the user's observation, which has certain limitations. potential safety hazards, for this reason, we propose a small suspension steering structure
