Description

Technical Field

[0001] This utility model relates to a shock absorber device, and more particularly to an adjustable shock absorber gas cylinder device. Background Technology

[0002] Shock absorbers are often installed on vehicles such as motorcycles and cars to reduce vibrations caused by the road surface when the vehicle is in motion, so that drivers and passengers can have a comfortable ride.

[0003] Shock absorbers typically consist of a spring and a gas cylinder. Vibrations generated by a vehicle traveling on uneven roads are primarily absorbed by the spring. After absorbing the vibrations, the spring will rebound, generating oscillations. At this point, a piston mechanism is needed to slow down the spring's extension and contraction. To ensure the shock absorber's damping capacity meets the user's needs, most existing shock absorbers incorporate a damping adjustment device on the gas cylinder, with a working fluid flowing back and forth between the two.

[0004] Existing shock absorber adjustment devices mostly utilize a needle to selectively block the flow channel, controlling the flow rate of the working fluid into the piston assembly based on the area of ​​the blocked channel. However, because the needle is located inside the shock absorber, users cannot know the extent of the blockage and cannot precisely control the flow of the working fluid. Therefore, how to more accurately control the flow rate of the working fluid is a problem that the industry urgently needs to solve. Utility Model Content

[0005] The main purpose of this invention is to propose an adjustable shock absorber gas cylinder device, which solves the problem that users of existing shock absorber adjustment devices cannot know the degree of oil needle obstruction of the flow channel and cannot accurately control the flow of working fluid.

[0006] To achieve the above objectives, this utility model proposes an adjustable shock absorber cylinder device, which has the following features:

[0007] A bottle body, which has:

[0008] A piston component, which is movably located within the bottle body;

[0009] A through-hole component, which is inserted through the bottle opening of the bottle body, and has the following characteristics:

[0010] A perforation that passes through the perforating member and connects to the internal space of the bottle;

[0011] Several connecting channels, each with a different size, and all connecting the through hole and the outer ring surface of the through piece;

[0012] An adjusting member, rotatably fitted onto the through member, and having:

[0013] One inlet, which is formed on the outer surface of the adjusting component;

[0014] A selection hole passes through the adjustment member and allows selective connection of the through hole to the inlet via one of the connection channels.

[0015] As described above, the adjustable shock absorber gas cylinder device, wherein...

[0016] The adjustment component also features:

[0017] Several card slots, the number of which corresponds to the number of connection channels;

[0018] The adjustable shock absorber cylinder device also features:

[0019] A stop member is disposed in the through member and is selectively protruding from the through member and engaging in one of the plurality of slots;

[0020] An elastic member is disposed in the fitting and tends to push the abutment toward the outer surface of the fitting.

[0021] As described above, the adjustable shock absorber gas cylinder device, wherein...

[0022] The adjustment component has:

[0023] At least one limiting groove is formed on the inner surface of the adjusting member;

[0024] The fitting has the following features:

[0025] A limiting part is provided on the outer surface of the through member and protrudes into the inner surface of the adjusting member. When the at least one limiting groove of the adjusting member rotates to abut against the limiting part, the adjusting member can no longer rotate.

[0026] As described above, the adjustable shock absorber gas cylinder device has two limiting grooves that are respectively aligned with two of the connecting channels in the axial direction of the adjusting member, and the two connecting channels are adjacent to each other.

[0027] As described above, in the adjustable shock absorber gas cylinder device, the adjusting element has:

[0028] A protrusion is disposed between the two limiting grooves, and the minimum distance between the protrusion and the central axis of the adjusting member is less than the radius of the limiting part.

[0029] As described above, in the adjustable shock absorber gas cylinder device, the through-feed member has:

[0030] A limiting part is provided on the outer surface of the through member and protrudes into the inner surface of the adjusting member;

[0031] The adjustment component has:

[0032] A protrusion is provided on the inner surface of the adjusting member, and the minimum distance between the protrusion and the central axis of the adjusting member is less than the radius of the limiting part.

[0033] The advantage of this invention lies in that, by rotating the adjusting component, the selection hole can be connected to different connection channels, thereby adjusting the flow rate of the working fluid into the bottle. This solves the problem that when using only an oil needle, the user cannot know the degree to which the oil needle obstructs the flow channel, and cannot accurately control the flow of the working fluid. Furthermore, the design of the abutment, limiting groove, and limiting part ensures that the user is not unsure whether the selection hole is aligned with the connection channel or which connection channel the selection hole aligns with when rotating the adjusting component.

[0041] Please refer to Figure 1 and Figure 3 This utility model proposes an adjustable shock absorber gas cylinder device, which can be directly installed on an axle or installed on an axle via a shock absorber adjustment device A. The adjustable shock absorber gas cylinder device has a cylinder body 10, a through-hole member 20 and an adjustment member 30, and may optionally have a backing member 40 and an elastic member 50.

[0042] Please refer to Figure 2 and Figure 4The bottle body 10 has a piston 11, which is movably located within the bottle body 10. Specifically, the piston 11 is annularly fitted to the inner wall surface of the bottle body 10, so that the piston 11 can divide the internal space of the bottle body 10 into two independent spaces.

[0043] Please refer to Figure 3 and Figure 5 The through-hole 20 is inserted through the mouth of the bottle body 10 and has a through hole 21, several connecting channels 22, and a limiting part 23. The through hole 21 passes through the through-hole 20 and communicates with the internal space of the bottle body 10. The connecting channels 22 connect the through hole 21 and the outer ring surface of the through-hole 20, and the dimensions of each connecting channel 22 are different. Specifically, in this embodiment, the connecting channels 22 are arranged in order of diameter around the outer ring surface of the through-hole 20 and communicate with the through hole 21. In other embodiments, the arrangement order of the connecting channels 22 is not limited to this. The limiting part 23 is disposed on the outer surface of the through-hole 20 and protrudes outward. In this embodiment, the limiting part 23 is located at the end of the through-hole 20 away from the mouth of the bottle body 10. In other embodiments, the position of the limiting part 23 is not limited to this.

[0044] Please refer to Figure 3 , Figures 5 to 7 The adjusting member 30 is rotatably fitted onto the through member 20 and has an inlet 31, a selection hole 32, at least one limiting groove 33, a protrusion 34, and several slots 35. Please refer to... Figure 5 An inlet 31 is formed on the outer surface of the adjusting member 30. A selection hole 32 penetrates the adjusting member 30 and can selectively connect the perforation 21 to the inlet 31 through one of the connecting channels 22. In other words, the selection hole 32 connects to the inlet 31 and selectively connects to one of the connecting channels 22. Thus, the working fluid can flow into one of the connecting channels 22 through the inlet 31 and then flow into the internal space of the bottle 10 through the perforation 21. Therefore, the user can control the speed at which the fluid flows into the bottle 10 by selecting different connecting channels 22.

[0045] Please refer to Figure 6A limiting groove 33 is formed on the inner surface of the adjusting member 30. When the limiting groove 33 of the adjusting member 30 rotates to abut against the limiting part 23, the adjusting member 30 cannot continue to rotate. In this embodiment, the adjusting member 30 has two limiting grooves 33, which are respectively aligned with two connecting channels 22 in the axial direction of the adjusting member, and the two connecting channels 22 are adjacent to each other. Specifically, the two limiting grooves 33 are respectively aligned with the connecting channel 22 with the largest diameter and the connecting channel 22 with the smallest diameter in the axial direction of the adjusting member, and the two limiting grooves 33 restrict the adjusting member 30 from rotating from the connecting channel 22 with the largest diameter to the connecting channel 22 with the smallest diameter, or from the connecting channel 22 with the smallest diameter to the connecting channel 22 with the largest diameter. A protrusion 34 is disposed between the two limiting grooves 33, and the minimum distance between the protrusion 34 and the central axis of the adjusting member 30 is less than the radius of the limiting part 23, thereby restricting the rotation direction of the adjusting member 30. In other embodiments, the adjusting member 30 may only have a limiting groove 33 or a protrusion 34, as long as it can limit the rotation direction of the adjusting member 30 so that the adjusting member 30 does not rotate a full circle. Please refer to Figure 7 The slots 35 are formed on the inner surface of the adjusting member 30, and the number of slots 35 corresponds to the number of connecting channels 22.

[0046] Please refer to Figure 7 A stop member 40 is disposed in the through member 20 and can selectively protrude from the through member 20 and engage in one of the slots 35. An elastic member 50 is disposed in the through member 20 and tends to push the stop member 40 toward the outer surface of the through member 20. When the elastic member 50 pushes the stop member 40 into one of the slots 35, the connecting channel 22 corresponding to the slot 35 is connected to the selection hole 32. Therefore, the user can determine whether the connecting channel 22 is connected to the selection hole 32 based on whether the stop member 40 is engaged in the slot 35.

[0047] In this embodiment, the present invention is mounted on the axle via a shock-absorbing adjustment device A, and the working fluid used during braking can flow into the present invention through the shock-absorbing adjustment device A. Therefore, the working fluid in the shock-absorbing adjustment device A can be roughly adjusted via an oil needle, and when the working fluid flows into the present invention, the flow rate of the working fluid into the bottle 10 can be precisely adjusted by selecting different connection channels 22.

[0048] When the working fluid flows into this invention, the user can rotate the adjusting member 30 to align the selection hole 32 on the adjusting member 30 with one of the connecting channels 22. At this time, the elastic member 50 will push the abutment member 40 towards the outer surface of the through member 20 until it engages with one of the slots 35, so that the user knows that the selection hole 32 and the connecting channel 22 are aligned when rotating. In this way, the working fluid can flow into one of the connecting channels 22 through the inlet 31, and then flow into the internal space of the bottle body 10 through the perforation 21, completing the flow of the working fluid.

[0049] The advantage of this invention lies in that, by rotating the adjusting member 30, the selection hole 32 can be connected to different connecting channels 22, thereby precisely adjusting the flow rate of the working fluid into the bottle 10. This solves the problem that when using only an oil needle, the user cannot know the degree to which the oil needle obstructs the flow channel and cannot accurately control the flow of the working fluid. Simultaneously, the design of the abutment member 40, the limiting groove 33, and the limiting part 23 ensures that when rotating the adjusting member 30, the user is not unsure whether the selection hole 32 is aligned with the connecting channel 22 or which connecting channel 22 the selection hole 32 is aligned with.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model.
