Abstract
Description
Technical Field
[0001] This invention relates to a shock absorber device, and more particularly to an adjustable shock absorber gas cylinder device. Prior Technology
[0002] Shock absorbers are often installed on vehicles such as locomotives and automobiles 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 to which the flow channel is blocked 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. Summary of the Invention
[0005] The main objective of this invention is to provide an adjustable shock absorber cylinder device, which solves the problem that users of existing shock absorber adjustment devices cannot know the degree to which the oil needle blocks the flow channel and cannot accurately control the flow of the working fluid.
[0006] To achieve the above objectives, the present invention proposes an adjustable shock absorber cylinder device, which has the following features: A bottle body, which has: A piston component, movably located within the bottle body; A through-hole component, which is inserted through the bottle opening of the bottle body, and has the following characteristics: A perforation extends through the perforating component and connects to the internal space of the bottle; Multiple connecting channels, each with a different size, and all connecting to the through hole and the outer circumferential surface of the through piece; An adjusting member, rotatably fitted onto the through member, and having: An inlet is formed on the outer surface of the adjusting element; A selection hole passes through the adjustment member and allows selective connection of the through hole to the inlet via one of the connecting channels; in, This adjustment component further features: The number of card slots corresponds to the number of connection channels; This adjustable shock absorber cylinder device further features: An abutment is disposed in the through-piece, and the abutment can selectively protrude from the through-piece and engage in one of the plurality of slots; when the abutment is engaged in one of the slots, the connecting channel corresponding to the slot is connected to the selection hole.
[0007] As described above, the adjustable shock absorber cylinder device, wherein, This adjustable shock absorber cylinder device further features: An elastic member is disposed in the fitting and tends to push the abutment toward the outer surface of the fitting.
[0008] As described above, the adjustable shock absorber cylinder device, wherein, The adjustment component has: At least one limiting groove is formed on the inner surface of the adjusting member; The fitting has: 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.
[0009] 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.
[0010] As described above, in the adjustable shock absorber cylinder device, the adjusting element has: 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.
[0011] As described above, in the adjustable shock absorber cylinder device, the adjusting element has: The fitting has: A limiting part is provided on the outer surface of the through member and protrudes into the inner surface of the adjusting member; The adjustment component has: 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.
[0012] The advantage of this invention lies in that, by rotating the adjusting member, 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 and the connection channel are aligned, or which connection channel the selection hole aligns with, when rotating the adjusting member.

Implementation
[0014] Please refer to Figures 1 and 3. This invention proposes an adjustable shock absorber cylinder device, which can be directly mounted on an axle or mounted on an axle via a shock absorber adjustment device A. The adjustable shock absorber cylinder device has a cylinder body 10, a through-hole member 20, and an adjustment member 30, and may optionally have a stop member 40 and an elastic member 50.
[0015] Please refer to Figures 2 and 4. The 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.
[0016] Please refer to Figures 3 and 5. The through-hole 20 passes through the bottle opening of the bottle body 10 and has a through hole 21, a plurality of connecting channels 22, and a limiting part 23. The through hole 21 penetrates 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 annular surface of the through-hole 20, and each connecting channel 22 has a different size. Specifically, in this embodiment, the connecting channels 22 are arranged sequentially around the outer annular surface of the through-hole 20 according to their diameter 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 bottle opening of the bottle body 10. In other embodiments, the position of the limiting part 23 is not limited to this.
[0017] Please refer to Figures 3, 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 a plurality of slots 35. Please refer to Figure 5. The inlet 31 is formed on the outer surface of the adjusting member 30. The selection hole 32 penetrates the adjusting member 30 and can selectively connect the through hole 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 through hole 21. Therefore, the user can control the speed at which the fluid flows into the bottle 10 by selecting different connecting channels 22.
[0018] Please refer to Figure 6. A 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 portion 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 portion 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.
[0019] Please refer to Figure 7. The abutment 40 is disposed within the through-piece 20 and can selectively protrude from the through-piece 20 and engage in one of the slots 35. The elastic member 50 is disposed within the through-piece 20 and tends to push the abutment 40 toward the outer surface of the through-piece 20. When the elastic member 50 pushes the abutment 40 into one of the slots 35, the connecting channel 22 corresponding to the slot 35 communicates with 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 abutment 40 is engaged in the slot 35.
[0020] In this embodiment, the present invention is mounted on the axle via a shock absorber adjustment device A, and the working fluid used during braking can flow into the present invention via the shock absorber adjustment device A. Therefore, the working fluid in the shock absorber 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.
[0021] When the working fluid flows into the present 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 toward 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, thus completing the flow of the working fluid.
[0022] The advantage of this invention is that by rotating the adjusting member 30, the selection hole 32 can be connected to different connection 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. At the same time, the design of the abutment member 40, the limiting groove 33, and the limiting part 23 also allows the user to avoid the problem of not knowing whether the selection hole 32 is aligned with the connection channel 22 or which connection channel 22 the selection hole 32 is aligned with when rotating the adjusting member 30.
