Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically a quick-release shock absorber. Background Technology

[0002] The primary function of a motorcycle shock absorber is to cushion and absorb impacts from the ground, ensuring stability and rider comfort. Shock absorbers effectively buffer impacts through springs and damping mechanisms, keeping the vehicle stable and providing a pleasant riding experience. Shock absorber materials typically include aluminum alloy, steel, or carbon fiber. Aluminum alloy shock absorbers are lighter and have better heat dissipation, while steel shock absorbers are more durable. Carbon fiber shock absorbers offer even greater weight reduction but are more expensive. Many motorcycle front shock absorbers are adjustable to adapt to different road conditions and rider needs, such as by adjusting preload or rebound speed to change the shock absorber's performance.

[0003] A motorcycle front shock absorber mainly consists of components such as a fork, base, damping spring, piston rod, oil seal, and dust cover, and is filled with damping oil. When the shock absorber spring is compressed, the damping oil flows through the free valve and return oil hole; when the spring rebounds, the free valve closes, and the damping oil flows through the damping hole, thus suppressing the spring's rebound. A good shock absorption system can keep the vehicle stable and ensure a comfortable driving experience.

[0004] According to the authorization announcement number CN 216343634 U, a shock absorber with easy replacement of lifting rings is disclosed. Its structure includes a shock absorber body, and base plates are provided at both ends of the shock absorber body. Each base plate is fixedly provided with an assembly seat at the end opposite to the shock absorber body. A locking hole for inserting a locking component is opened at the center of the side of the assembly seat opposite to the base plate. The inner wall of the locking hole is provided with two sliding grooves at equal intervals and circumferentially. A locking pin is movably provided in each sliding groove. Each locking pin is connected to a locking component for controlling its extension or retraction into the sliding groove. The inner end of the locking component is provided with a locking groove that cooperates with the locking pin. The outer end of the locking component is connected to a lifting ring.

[0005] Motorcycle shock absorbers need to be inspected and replaced after long-term use. Existing shock absorbers cannot be quickly disassembled, which affects the speed of inspection and replacement. Therefore, a quick-release shock absorber is needed. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-release shock absorber, which allows for quick installation and disassembly between the piston connecting rod and the fixed seat through the setting of the fixing block and the deformation groove.

[0014] Preferably, an extension sleeve is installed on the outside of the sealing sleeve, and the inner wall of the extension sleeve is in close contact with the outer arc surface of the sleeve.

[0015] Preferably, the outer arc surface of the extension sleeve is provided with an annular groove, a ring locking sleeve is installed inside the annular groove, and a locking bolt is installed in the middle of the ring locking sleeve.

[0016] Preferably, a second fixing seat is installed at the bottom of the sleeve, a second mounting buckle is installed at the lower part of the second fixing seat, and a spring is installed between the first fixing seat and the second fixing seat.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5 As shown, a quick-release shock absorber includes a sleeve 1, a sealing sleeve 2 installed on the upper part of the sleeve 1, a piston 3 slidably installed inside the sleeve 1, a piston connecting rod 4 installed through the middle of the sealing sleeve 2 on the upper part of the piston 3, and a first fixed seat 7 snapped onto the upper part of the piston connecting rod 4. A sealing ring 2 on the upper part of the sleeve 1 is used to seal the top of the sleeve 1 to prevent hydraulic oil leakage from the sleeve 1 from affecting the shock absorber's damping performance. The shock absorber achieves its damping effect by the piston 3 moving up and down inside the shock absorber. The piston connecting rod 4 connects the piston 3 to the first fixed seat 7. When the vehicle is subjected to vibration and impact due to uneven road surfaces or other factors, the piston connecting rod 4 pushes the piston 3 to move up and down inside the sleeve 1. During the movement of the piston 3, hydraulic fluid flows through a series of small holes, thereby generating damping force. This damping force can absorb and dissipate vibration energy, thereby reducing vehicle body bumps and swaying.

[0027] A fixing block 6 is installed on the top of the piston connecting rod 4. A deformation groove 8 is opened on the bottom of the first fixing seat 7 corresponding to the fixing block 6. The fixing block 6 is snapped into the inside of the deformation groove 8. A locking block 10 is installed through the fixing block 6 on the top of the first fixing seat 7. The fixing block 6 on the top of the piston connecting rod 4 is used to snap into the inside of the deformation groove 8 inside the first fixing seat 7, so that the piston connecting rod 4 and the first fixing seat 7 are connected. The locking block 10 is used to fix the fixing block 6 inside the deformation groove 8. When it is necessary to disassemble the shock absorber, pull the fixing buckle 12 to make the locking block 10 disengage from the locking groove 9. At this time, the first fixing seat 7 can be rotated. When the first fixing seat 7 is rotated, the fixing block 6 will rotate inside the deformation groove 8. When the fixing block 6 is rotated to the designated position, the first fixing seat 7 can be removed from the piston connecting rod 4, thereby achieving the purpose of disassembling the shock absorber.

[0028] Furthermore, a slot 9 is provided on the top of the first fixed seat 7, and the locking block 10 is slidably installed inside the slot 9. The slot 9 on the top of the first fixed seat 7 is used to install the locking block 10, so that the locking block 10 can slide inside the slot 9 to fix the fixing block 6 inside the deformation groove 8, so that the piston connecting rod 4 is connected to the first fixed seat 7.

[0029] Furthermore, two sets of circular holes 11 are symmetrically provided in the middle of the fixing block 6. The bottom of the locking block 10 is engaged with the inside of the two sets of circular holes 11, and two sets of fixing buckles 12 are symmetrically installed on the top of the locking block 10. In the above design, the circular holes 11 in the middle of the fixing block 6 are used for inserting the locking block 10. By pushing the locking block 10, the bottom of the locking block 10 is pulled into the inside of the circular holes 11, which can fix the fixing block 6 and prevent the fixing block 6 from rotating inside the deformation inner groove 8, ensuring that the shock absorber can work normally.

[0030] Furthermore, a first mounting buckle 13 is installed on the upper part of the first fixing base 7. A movable groove 14 is opened in the middle of the first mounting buckle 13 corresponding to the locking block 10. The locking block 10 is slidably installed inside the movable groove 14. In the above design, the first mounting buckle 13 on the upper part of the first fixing base 7 is used to connect the shock absorber to the motorcycle. The movable groove 14 is used to facilitate the movement of the locking block 10 when it is pulled. At the same time, the movable groove 14 can limit the locking block 10 to prevent it from falling off and affecting the installation of the shock absorber.

[0031] Furthermore, the bottom outer arc surface of the sealing sleeve 2 is tightly fitted to the inner wall of the sleeve 1, and a sealing ring 15 is installed inside the sleeve 1 on the outer arc surface of the sealing sleeve 2, with the outer arc surface of the sealing ring 15 tightly fitted to the inner wall of the sleeve 1. With this design, the sealing sleeve 2 is used to seal one end of the sleeve 1, preventing leakage of hydraulic oil inside the sleeve 1 during shock absorber operation. The sealing ring 15 further enhances the sealing performance between the sleeve 1 and the sealing sleeve 2, ensuring the service life and shock absorption performance of the shock absorber.

[0032] Furthermore, an extension sleeve 16 is installed on the outside of the sealing sleeve 2, and the inner wall of the extension sleeve 16 is tightly fitted with the outer arc surface of the sleeve 1. In the above design, the extension sleeve 16 is used to reinforce the connection between the sleeve 1 and the sealing sleeve 2, and at the same time can prevent external dust from entering the interior of the sleeve 1, ensuring the safety of the shock absorber.

[0033] Furthermore, an annular groove 17 is formed on the outer arc surface of the extension sleeve 16, and a locking sleeve 18 is installed inside the annular groove 17. A locking bolt 19 is installed in the middle of the locking sleeve 18. In the above design, the annular groove 17 is used to install the locking sleeve 18, the locking sleeve 18 is used to reinforce the connection between the extension sleeve 16 and the sleeve 1, and to prevent the extension sleeve 16 from detaching from the outer arc surface of the sleeve 1. The locking bolt 19 is used to fix the locking sleeve 18 inside the annular groove 17.

[0034] Furthermore, a second fixing seat 20 is installed at the bottom of the sleeve 1, and a second mounting buckle 21 is installed at the lower part of the second fixing seat 20. A spring 22 is installed between the first fixing seat 7 and the second fixing seat 20. In the above design, the second fixing seat 20 and the second mounting buckle 21 at the bottom of the sleeve 1 provide support and can fix the shock absorber to the motorcycle, ensuring that the shock absorber can work normally under various road conditions, thereby improving the vehicle's driving stability and ride comfort. The spring 22 can absorb the impact force transmitted from the road surface, reduce the vibration of the vehicle body, and thus improve passenger comfort.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
