Description

Improvement of bicycle suspension vertical tube

This creation is related to bicycles, and in particular to an improvement of a bicycle suspension vertical tube for shock absorption.

The improved suspension vertical tube of a bicycle can also be called the vertical tube or stem. Its English translation is stem. Its main purpose is to connect the front fork and the handlebars so that when the rider turns the handlebar tube, the front fork vertical tube can be driven to rotate to achieve the purpose of turning.

However, due to the existing bicycle suspension tube improvements, handlebars, front forks and other steering structures that are too rigid, the rider's hands are forced to maintain the same angle for a long time. The vibration generated by riding on bumpy roads or riding for a long time can easily cause discomfort and fatigue in the rider's hands, making it impossible to hold and control the bicycle steadily, increasing the risk of riding.

Therefore, it is necessary to provide a novel and progressive bicycle suspension vertical tube improvement to solve the above problems.

The main purpose of this invention is to provide an improved bicycle suspension vertical tube, which can reduce the vibration force caused by riding on bumpy roads by making the second component move relative to the first component and cooperate with the shock-absorbing mechanism to reduce the discomfort of the rider's hands and ensure that the rider can hold the handlebars stably for control.

To achieve the above-mentioned purpose, the invention provides an improved bicycle suspension vertical tube, comprising: a main body and a suspension mechanism. The main body comprises a first component and a second component, the first component is assembled to a front fork vertical tube, the second component is assembled to a handlebar tube, the second component can be relatively movably connected to the first component, the first component and the second component jointly enclose a containing space, and one of the first component and the second component is provided with an adjustment hole connected to the containing space. The shock-absorbing mechanism is accommodated in the accommodation space to abut between the first component and the second component. The shock-absorbing mechanism includes a damping unit and an adjustment unit that are interconnected. The adjustment unit is movably positioned between the adjustment hole and the damping unit. The adjustment unit includes a coupling portion facing the adjustment hole. The coupling portion is coupled with a tool that passes through the adjustment hole. The tool can be used to drive the adjustment unit to move to change the damping value of the damping unit.

The "one" or "at least one" before the terms mentioned in the text does not limit the quantity. It can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained first.

Please refer to Figures 1 to 5, which show the first embodiment of the present invention. The bicycle shock-absorbing vertical tube improvement of the present invention includes: a main body 1 and a shock-absorbing mechanism 5.

The main body 1 includes a first component 2 and a second component 3. The first component 2 is assembled to a front fork stem 61, and the second component 3 is assembled to a handlebar 62. The second component 3 can be relatively movably connected to the first component 2. The first component 2 and the second component 3 together enclose a receiving space 4. One of the first component 2 and the second component 3 is provided with an adjustment hole 25 connected to the receiving space 4.

More specifically, the first component 2 includes a first assembly portion 21 and a seat portion 22, the first assembly portion 21 is sleeved on the front fork stem 61, the seat portion 22 protrudes laterally from the first assembly portion 21, the seat portion 22 is recessed with a chamber 23 and is provided with the adjustment hole 25, the second component 3 includes a second assembly portion 31 and a cover 32, the second assembly portion 31 is sleeved on the handlebar tube 62, the cover 32 protrudes laterally from the second assembly portion 31, and the cover 32 covers the chamber 23 to jointly enclose the accommodation space 4.

The shock absorbing mechanism 5 is accommodated in the accommodation space 4 to abut against the first component 2 and the second component 3. The structural design of the shock absorbing mechanism 5 being accommodated in the accommodation space 4 can effectively ensure the smooth operation of the shock absorbing mechanism 5 and the integrity of the component structure, and the main body 1 can maintain a more complete and continuous appearance, so that the overall appearance of the improved bicycle shock absorbing vertical tube can present a high-quality visual experience.

In more detail, the shock absorbing mechanism 5 includes a damping unit 51 and an adjusting unit 56 which are interconnected. The adjusting unit 56 is movably positioned between the adjusting hole 25 and the damping unit 51. In this embodiment, the adjusting unit 56 is movably screwed to the main body 1. The adjusting unit 56 includes a coupling portion 57 facing the adjusting hole 25. The coupling portion 57 It is a non-circular hole. The coupling part 57 is coaxially arranged with the adjustment hole 25. The coupling part 57 is used to couple with a tool (such as a hexagonal wrench, a screwdriver, etc.) that passes through the adjustment hole 25. The tool can drive the adjustment unit 56 to move to change the damping value of the damping unit, so that the rider can freely adjust the damping value of the damping unit according to the needs, that is, the softness and hardness of the hand feel.

In more detail, the damping unit 51 includes an elastic body 52, which is sandwiched between the first component 2 and the second component 3. When the second component 3 pivots relative to the first component 2 due to vibration, the elastic body 52 can provide resistance to the second component 3, thereby having the effect of buffering and shock absorption. In this embodiment, the elastic body 52 is made of high-strength rubber material, so that the elastic body 52 has many advantages such as good tensile strength, tear resistance, load resistance, shock resistance, and wear resistance. In addition, the elastic body can also be made of rubber material.

Of course, this invention is not limited to the type of the elastic body 52. For example, but not limited to the second embodiment of FIG. 6, the difference between the second embodiment and the first embodiment is that the elastic body 52A is a spring, which has the advantage of easy availability of materials.

Referring again to the first embodiment of FIG. 1 to FIG. 5 , the adjusting unit 56 is in the shape of a circular plate, and the seat portion 22 further includes a side opening 24, the side opening 24 is connected to the chamber 23 so as to install or remove the elastic body 52 therefrom, and the side opening 24 provides a margin space for the elastic body 52 to deform, and the outer side wall of the adjusting unit 56 is screwed to the wall portion surrounding the chamber 23. The adjustment unit 56 and the elastic body 52 are coaxially arranged. The radial dimension of the adjustment unit 56 is larger than the radial dimension of the elastic body 52 to ensure that it can completely abut against the end surface of the elastic body 52. Part of the elastic body 52 is accommodated in the chamber 23 to have a limited position effect, and the other part of the elastic body 52 protrudes from the seat 22 to facilitate the user to pick and take.

It is worth mentioning that the damping unit 51 further includes a first abutting surface 54 and a second abutting surface 55 opposite to each other. The first abutting surface 54 abuts against the adjusting unit 56, and the second abutting surface 55 abuts against the second component 3; wherein the outer contour of the longitudinal section of the second abutting surface 55 is arc-shaped, and the second component 3 is tangent to the second abutting surface 55. When the second component 3 pivots downward relative to the first component 2, the second component 3 can smoothly stabilize the pivot direction along the second abutting surface 55, and since the arc-shaped second abutting surface 55 can provide more comprehensive different angle positions for the second component 3 to abut, the pressure resistance can be continuously transmitted to the elastic body 52 during the pivoting process.

Specifically, the damping unit 51 further includes a cover 53, which is disposed on one side of the elastic body 52, and the adjusting unit 56 is against the other side of the elastic body 52. One of the cover 53 and the adjusting unit 56 is against the first component 2, and the other is against the second component 3. The cover 53 can protect the structural integrity of the elastic body 52 and can evenly transfer the pressure from the second component 3 to the elastic body 52, so that the elastic body 52 can be evenly stressed and stably compressed and deformed. Specifically, the elastic body 52 is in the shape of a circular tube, and the cover 53 includes a cover portion 531 and an insert portion 532. The insert portion 532 protrudes laterally from the cover portion 531, and the insert portion 532 is inserted into the elastic body 52. The cover portion 531 covers and presses against the abutment surface of the elastic body 52. One side of the cover portion 531 facing away from the elastic body 52 is the second abutment surface 55. In this way, the cover portion 531 can convert the compressive force from the second component 3 at different positions into a linear force, and stably and evenly press against the elastic body 52.

Please refer to the third embodiment of FIG. 7 . The difference between the third embodiment and the first embodiment is that the elastic body 52B directly abuts against the second component 3. The end surface of the elastic body 52B abutting against the second component 3 is the second abutting surface 55B. Compared with the first embodiment, the third embodiment has the advantages of simplifying parts and reducing assembly steps.
