Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a motorcycle shock absorber with shock absorption function. Background Technology

[0002] On May 16, 2023, the applicant filed a patent application with patent number 202321181033.1, entitled "A Novel Bidirectional Damping Adjustable Shock Absorber," which specifically discloses that: when the shock absorber is subjected to impact, the two ends of the shock absorber are compressed towards each other, thereby driving the piston rod and outer cylinder to squeeze towards the hydraulic cylinder, the first inner cylinder, and the second inner cylinder. One end of the outer cylinder is embedded in the third chamber and moves along the third chamber. The piston rod squeezes the second spring inward, causing the piston to squeeze the damping oil in the lower part of the first chamber, so that the damping oil flows through the first flow channel. The damping oil is introduced into the first adjustment mounting groove, and the flow area of ​​the damping oil is adjusted by the first adjustment device, thereby adjusting the compression damping of the shock absorber. Part of the damping oil flowing through the first adjustment device enters the airbag device for storage through the third flow channel, and the other part enters the second chamber through the second adjustment mounting groove and the second flow channel, and then enters the upper part of the first chamber through the through hole on the first inner cylinder, thereby improving the flow path of the damping oil. At the same time, under the adjustment of the first adjustment device, the energy consumption of the damping oil is increased, thereby improving the damping effect of the shock absorber.

[0003] In actual use, the damping oil stored in the airbag device pushes the airbag piston to compress the gas in the air chamber, and causes the pressure in the oil chamber to change, thereby balancing the compression force during the shock absorption process and improving the shock absorption effect. However, the compression rate of the gas is non-linear, which means that the gas in the air chamber is prone to cause non-linear response during the compression / rebound process of the shock absorber, affecting riding comfort and handling stability.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] The embodiment of this utility model is as follows:

[0027] refer to Figures 1 to 6As shown, a motorcycle shock absorber with shock absorption function includes a base 1, a shock absorber body, a first adjustment device 13, a second adjustment device 14, and an airbag device 15. The shock absorber body, the first adjustment device 13, the second adjustment device 14, and the airbag device 15 are respectively mounted on the base 1. The base 1 has a first flow channel 107 connecting the shock absorber body and the first adjustment device 13, a second flow channel 108 connecting the shock absorber body and the second adjustment device 14, a third flow channel 109 connecting the first adjustment device 13 and the airbag device 15, and a fourth flow channel 110 connecting the second adjustment device 14 and the airbag device 15. The airbag device 15 includes an airbag cylinder 151 with openings at both ends. One end of the airbag cylinder 151 is connected to the base 1, and the other end of the airbag cylinder 151 is provided with an airbag sealing cap 152. The airbag sealing cap 152 has a connecting hole 153 in the middle. An adjusting rod 154 is rotatably provided. An axially movable airbag piston 155 is provided inside the airbag cylinder 151. The airbag piston 155 divides the airbag cylinder 151 into an air chamber 201 and an oil chamber 202. An axially movable adjusting valve core 156 is provided inside the air chamber 201. A slot 157 for the adjusting rod 154 to pass through is provided at the central axis of the adjusting valve core 156. An axially penetrating part is provided on the adjusting valve core 156 and located around the slot 157. The main air passage 158 has a turntable 159 rotatably mounted on the regulating valve core 156, and the turntable 159 is engaged with the regulating rod 154. The turntable 159 has a plurality of throttling orifice groups 160 distributed along the axial direction, and the orifice diameter of each throttling orifice group 160 is different. When the regulating rod 154 is rotated, the turntable 159 rotates, so that one of the different throttling orifice groups 160 is aligned with the main air passage 158, thereby changing the gas flow cross-sectional area and realizing graded or stepless adjustment of the damping force.

[0028] This motorcycle shock absorber with shock absorption function integrates the shock absorber body, first adjustment device 13, second adjustment device 14, and airbag device 15 on the base 1, and sets up interconnected first flow channels 107, second flow channels 108, third flow channels 109, and fourth flow channels 110, so that the damping oil can flow orderly between multiple chambers and adjustment devices. In particular, a turntable 159 structure driven by a rotatable adjustment rod 154 is introduced into the airbag device 15, which, together with the adjustment valve core 156 with different orifice groups 160, allows the user to select different orifice groups 160 to align with the main air channel 158 simply by rotating the adjustment rod 154, thereby realizing graded or stepless adjustment of the gas flow cross-sectional area. This structure effectively transforms the original nonlinear damping response caused by the nonlinearity of gas compressibility into a linear or quasi-linear damping characteristic that can be precisely controlled by mechanical adjustment, significantly improving the linearity of the shock absorber's response during compression / rebound, thereby improving the riding comfort and handling stability of the motorcycle.

[0029] Furthermore, the regulating valve core 156 is provided with a sealing ring 161 on its outer periphery, which forms a sliding seal with the inner wall of the airbag to prevent gas leakage. This ensures a reliable sliding seal structure between the regulating valve core 156 and the inner wall of the airbag cylinder 151, effectively preventing leakage of high-pressure gas in the air chamber 201 during the axial movement of the regulating valve core 156. This design not only ensures the stability of the pressure in the air chamber 201 and guarantees the damping adjustment accuracy, but also extends the service life of the airbag device 15 and improves the sealing reliability and working durability of the entire shock absorption system.

[0030] Furthermore, the top of the adjusting rod 154 is provided with a nut 162, and the airbag sealing cap 152 is provided with a recess 163 for the nut to be inserted. The surface of the nut 162 is provided with a damping level mark, so that after the nut 162 is inserted, it can limit the position and make it easy for the user to intuitively identify the currently selected damping level. This structure simplifies the adjustment operation, improves the human-computer interaction experience, and is especially suitable for quickly and accurately switching damping modes during riding, thus enhancing the practicality and user-friendliness of the product.

[0031] Specifically, the shock absorber body includes a hydraulic cylinder 2, a first inner cylinder 3, a second inner cylinder 4, an outer cylinder 5, a piston rod 6, a piston 7, a first spring 8, a second spring 9, a first sealing cover 10, a second sealing cover 11, and a third sealing cover 12. The base 1 is respectively provided with a first mounting groove 101, a first adjusting mounting groove 104, a second adjusting mounting groove 105, and an airbag mounting groove 106. The bottom surface of the first mounting groove 101 is recessed with a second mounting groove 102, and the bottom surface of the second mounting groove 102 is recessed with a third mounting groove 103. The first mounting groove 101, the second mounting groove 102, and the third mounting groove 103 have a stepped structure. One end of the first inner cylinder 3 is located within the third mounting groove 103. The other side has six through holes 16. One end of the second inner cylinder 4 is provided with a second mounting groove 102. One end of the hydraulic cylinder 2 is provided with a first mounting groove 101. The second inner cylinder 4 is sleeved on the first inner cylinder 3 and is spaced apart. The first sealing cap 10 is provided at the other end of the first inner cylinder 3 and the second inner cylinder 4. The hydraulic cylinder 2 is sleeved on the second inner cylinder 4 and is spaced apart. The second sealing cap 11 is provided at the other end of the hydraulic cylinder 2. One end of the outer cylinder 5 is provided between the second inner cylinder 4 and the hydraulic cylinder 2, and the other end of the outer cylinder 5 extends outward through the second sealing cap 11. The third sealing cap 12 is provided at the outer end of the outer cylinder 5. The hydraulic cylinder 2, the first inner cylinder 3, the second inner cylinder 4, and the outer cylinder 5 are coaxially distributed. The base 1 The first inner cylinder 3 and the first sealing cap 10 constitute the first chamber 111. The base 1, the first inner cylinder 3, the second inner cylinder 4, and the first sealing cap 10 constitute the second chamber 112. The base 1, the second inner cylinder 4, the hydraulic cylinder 2, and the second sealing cap 11 constitute the third chamber 113. The outer cylinder 5, the second sealing cap 11, and the third sealing cap 12 constitute the fourth chamber 114. The piston rod 6 is located in the fourth chamber 114, with one end fixed to the third sealing cap 12 and the other end extending through the first sealing cap 10 into the first chamber 111. The piston 7 is located on the piston rod 6 and within the first chamber 111. The first spring 8 is sleeved on the piston rod 6 and distributed between the first sealing cap 10 and the third sealing cap 12. The second spring... Nine components are mounted on the piston rod 6 and distributed between the first sealing cap 10 and the piston 7. The base 1 is provided with a first flow channel 107 connecting the first chamber 111 and the first adjustment mounting groove 104, a second flow channel 108 connecting the second chamber 112 and the second adjustment mounting groove 105, a third flow channel 109 connecting the first adjustment mounting groove 104 and the airbag mounting groove 106, and a fourth flow channel 110 connecting the second adjustment mounting groove 105 and the airbag mounting groove 106. The first adjustment mounting groove 104 and the second adjustment mounting groove 105 are connected. The first adjustment device 13 and the second adjustment device 14 are respectively provided on the first adjustment mounting groove 104 and the second adjustment mounting groove 105. The airbag device 15 is provided on the airbag mounting groove 106.An elastic element 17, which is an elastic bushing, is fitted onto the piston rod 6 and located within the fourth chamber 114.

[0032] When the shock absorber is impacted, its two ends compress towards each other, which in turn drives the piston rod 6 and outer cylinder 5 to press against the hydraulic cylinder 2, the first inner cylinder 3, and the second inner cylinder 4. One end of the outer cylinder 5 is embedded in the third chamber 113 and moves along the third chamber 113. The piston rod 6 presses the second spring 9 inward, which drives the piston 7 to press the damping oil in the lower part of the first chamber 111. This causes the damping oil to flow into the first adjusting mounting groove 104 through the first flow channel 107. The flow area of ​​the damping oil is adjusted by the first adjusting device 13, thereby adjusting the compression damping of the shock absorber. Part of the damping oil flowing through the first adjusting device 13 enters the airbag device 15 through the third flow channel 109 for storage, and the other part enters the second chamber 112 through the second adjusting mounting groove 105 and the second flow channel 108, and then enters the upper part of the first chamber 111 through the through hole 16 on the first inner cylinder 3, thereby improving the flow path of the damping oil. At the same time, the first adjusting device 13 adjusts the flow area of ​​the damping oil. Under the adjustment of setting 13, the energy consumption of damping oil is increased, thereby improving the damping effect of the shock absorber. In addition, during the compression process of the shock absorber, the first spring 8 plays a buffering role in the initial push of the damping oil by the piston rod 6 driving the piston 7, reducing the large impact reaction on the vehicle body, improving comfort, and enhancing the premium feel of the shock absorber. Furthermore, when the shock absorber rebounds, on the one hand, the damping oil in the airbag device 15 enters the second adjustment mounting groove 105 through the fourth flow channel 110, and on the other hand, the damping oil in the upper part of the first chamber 111 enters the second chamber 112 through the through hole 16, while simultaneously driving the damping oil in the second chamber 112 to enter the second adjustment mounting groove 105 through the second flow channel 108. Then, the flow area of ​​the damping oil is adjusted by the second adjustment device 14, thereby adjusting the rebound damping of the shock absorber, and the oil enters the lower part of the first chamber 111 through the first adjustment mounting groove 104 and the first flow channel 107.

[0033] In this embodiment, the base 1 is provided with a connecting part 18 that connects to the first adjustment mounting groove 104. The connecting part 18 has a tubular structure, which improves the strength of the base 1 and reduces the weight of the base 1, thereby improving the maneuverability of the vehicle in use. The base 1 is provided with a connecting plate 19 on the other side of the first adjustment mounting groove 104. The connecting plate 19 is provided with two mounting holes 20 to facilitate installation and ensure the strength of the installation. A connector 21 is installed at the mounting hole 20 to improve the convenience of installation and effectively absorb and disperse the installation stress, avoid connection failure or abnormal noise caused by high frequency vibration, and improve the safety and durability of long-term use.

[0034] Meanwhile, the lower end of the adjusting rod 154 is provided with a limiting block 164, which can effectively limit the axial movement range of the adjusting valve core 156 in the air bladder cylinder 151, prevent it from excessively extending or dislodging, and ensure that the transmission relationship between the turntable 159 and the adjusting valve core 156 is stable and reliable. This limiting structure improves the operating accuracy and mechanical life of the adjusting mechanism, avoids gear shift due to misoperation or vibration, and ensures the long-term effectiveness of the damping adjustment function.
