Description

Technical Field

[0001] This utility model relates to a damping rod, and more particularly to a damping rod in which the flow of damping oil during reciprocating motion does not interfere with each other. Background Technology

[0002] Traditional damping rods typically use hydraulic or threaded connections, which are relatively simple in structure and performance. Traditional damping rods mainly use threads to connect multiple parts. Due to the large machining tolerances of the threaded structure, the threads are prone to loosening or parts may detach abnormally when exposed to vibration or impact for a long time, which could affect the rider's safety. Utility Model Content

[0003] The main purpose of this invention is to provide a damping rod to overcome the problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A damping rod, disposed within a fork tube and integrated with a shock absorber base, the damping rod comprising:

[0006] The first rod body includes a rod shaft, an oleophobic structure located at one end of the rod shaft, and a fixing structure connected to one side of the oleophobic structure. The rod shaft is provided with an oleophobic channel, and the oleophobic structure is provided with at least one oil inlet hole communicating with the oleophobic channel and multiple oil outlet holes.

[0007] A sleeve is fitted onto the lower rod body and abuts against the oleophobic structure. An oil return space is provided between the sleeve and the rod body, which communicates with each of the oil drain holes. Multiple oil return holes are formed at the end of the sleeve away from the oleophobic structure, which communicate with the oil return space.

[0008] A connecting assembly, which is fitted onto the lower rod body and positioned on one side of the sleeve, covering the oil return space; and

[0009] An oil outlet connector is provided at one end of the lower rod body and has an oil outlet channel communicating with the oil venting channel.

[0010] Furthermore, the connecting assembly includes a connecting kit, a pressure plate, and a locking fastener. The connecting kit is sleeved on one end of the lower rod, the pressure plate is sleeved on the lower rod and abuts against the connecting kit, and the locking fastener is locked to the lower rod and applies pressure to the pressure plate for locking.

[0011] Furthermore, the diameter of the oleophobic structure is larger than the diameter of the rod body.

[0012] Furthermore, each of the oil drain holes extends from the vicinity of the rod body to the bottom of the oleophobic structure.

[0013] Furthermore, the oil inlet hole extends laterally through the lower rod body and connects to the oil drainage channel.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The damping rod of this invention is installed inside the fork tube filled with damping oil. When the damping rod rebounds against the fork tube, the damping oil completes the rebound oil drainage circuit through the drain hole, the return space and the return hole. When it is pressed down, the damping oil completes the pressing oil drainage circuit through the inlet hole, the oil drainage channel and the outlet channel of the connecting component, so as to achieve the effect of reciprocating motion without interference.

Detailed Implementation

[0023] The structures, proportions, and sizes illustrated in the accompanying diagrams of this manual are solely for the purpose of assisting those familiar with the art in understanding and reading the content disclosed herein. They are not intended to limit the feasibility of this creation and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, provided they do not affect the effectiveness or purpose of this creation, should still fall within the scope of the technical content disclosed herein. Furthermore, the use of terms such as "one," "two," and "above" in this manual is merely for clarity of description and not intended to limit the scope of this creation's feasibility. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this creation's feasibility.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows a three-dimensional schematic diagram, a three-dimensional exploded schematic diagram, a schematic diagram of the combination of the lower rod and the sleeve, and a schematic diagram of the combination assembly of the present invention. This embodiment provides a damping rod, which is installed inside a fork tube (not shown in the diagram) and combined with a shock absorber base (not shown in the diagram). The damping rod 1 mainly includes: a lower rod 10, a sleeve 11, a combination assembly 12, and an oil outlet connector 13. The lower rod 10 includes a rod body 100, an oil-draining structure 102, and a fixing structure 104. The oil-draining structure 102 is located at one end of the rod body 100, and the fixing structure 104 is connected to one side of the oil-draining structure 102. The rod body 100 is provided with an oil-draining channel 1000, and the oil-draining structure 102 is provided with an oil inlet hole 1020 and a plurality of oil outlet holes 10. 22. The oil inlet 1020 is connected to the oil drain channel 1000. The sleeve 11 is fitted onto the lower rod body 10 and abuts against the oil drain structure 102. The oil return space 110 between the sleeve 11 and the rod body 100 is connected to each oil drain hole 1022. The end of the sleeve 11 away from the oil drain structure 102 forms a plurality of oil return holes 112 connected to the oil return space 110. The connecting component 12 is fitted onto the lower rod body 10 and is set on one side of the sleeve 11 and covers the oil return space 110. The oil outlet connector 13 is set at one end of the lower rod body 10 and the oil outlet channel 130 is connected to the oil drain channel 1000.

[0026] refer to Figure 5 and Figure 6 As shown, Figure 1 Schematic diagram of the cross-sectional structure of the AA section line and Figure 1A cross-sectional structural diagram of the BB section. The damping rod 1 is installed inside the front fork tube (not shown in the drawing) and combined with the shock absorber base (not shown in the drawing). When the front fork tube depresses or rebounds, damping oil acts as a compression medium, flowing through the pressure of the damping rod 1 to achieve a buffering effect. Figure 5 As can be seen, since the diameter of the oleophobic structure 102 is larger than the diameter of the rod body 100, after the sleeve 11 is attached to the oleophobic structure 102, the structure of the rod body 100 having a smaller diameter than the oleophobic structure 102 allows the sleeve 11 and the rod body 100 to define an oil return space 110. At the same time, since each oil drain hole 1022 extends from the adjacent part of the rod body 100 to the bottom of the oleophobic structure 102, the damping oil entering from the oil return hole 112 at one end of the sleeve 11 flows through the oil return space 110 and is then discharged from the oil drain hole 1022 to the bottom of the oleophobic structure 102, thus completing the rebound oleophobic circuit (refer to the direction of the arrow).

[0027] For further reference Figure 6 As can be seen, since the oil inlet hole 1020 on the oil-draining structure 102 penetrates the lower rod body 10 laterally and connects to the oil-draining channel 1000, when the damping rod presses down on the fork tube, the damping oil is drawn upward through the oil inlet hole 1020 and discharged from the oil outlet channel 130 through the oil-draining channel 1000 to complete the downward pressure oil-draining circuit, so as to achieve the effect of reciprocating action without interference.

[0028] Furthermore, refer to Figure 4 The aforementioned connecting component 12 includes a connecting kit 120, a pressure plate 122, and a locking fastener 124. The connecting kit 120 is fitted onto one end of the lower rod 10, and the pressure plate 122 is fitted onto the lower rod 10 and abuts against the connecting kit 120. The locking fastener 124 is locked onto the lower rod 10 and applies pressure to the pressure plate 122 for locking. The locking fastener 124 (nut) locks the rod and achieves a downward pressure tightening effect through the pressure plate 122, thereby improving the overall locking strength of the damping rod 1. At the same time, the various parts in the damping rod 1 can be replaced with different specifications according to the user's needs to improve the overall shock absorption comfort and performance during use.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
