[0002] To quickly dampen vibrations between the chassis and body, and improve the smoothness and comfort of driving, shock absorbers are generally installed in the car suspension system. By using shock absorbers to reduce vibrations between the body and chassis, the smoothness and comfort of driving are increased.
[0003] However, the existing devices have the following shortcomings during use:
[0004] Existing shock absorbers have a relatively simple damping adjustment function, which cannot adjust the speed in real time and accurately according to the actual motion state. For example, when the road conditions change during vehicle operation, it is not convenient to quickly adjust the damping force, which affects the comfort and stability of the vehicle.
[0005] Therefore, we propose a novel variable-speed real-time adjustable shock absorber and its usage method to solve the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide a novel real-time adjustable shock absorber and its usage method.

[0017] A method for using a novel variable-speed real-time adjustable shock absorber includes the following steps:
[0018] Step 1: Installation Operation Stage. The shock absorber is installed on the vehicle through the first and second adjustment installation mechanisms. According to the installation requirements, the electromagnetic clutch is disengaged, the rotating cap is rotated to drive the rotating rod and the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear to drive the threaded rod to rotate. The mounting plate moves along the limit rod. The lifting lug is adjusted to the appropriate position. After the position is determined, the electromagnetic clutch is engaged to lock the position of the threaded rod and complete the installation.
[0019] Step 2: Elasticity adjustment stage. When it is necessary to adjust the elasticity of the reset spring, pull the pull ring to move the moving plate in the groove, compress the limit spring, and make the locking rod disengage from the limit hole. Then rotate the adjustment plate to make the rotating sleeve move along the threaded groove. The moving ring moves with the rotating sleeve, and the slider slides and guides in the groove. After adjusting to the appropriate elasticity, release the pull ring. The limit spring pushes the moving plate to reset, and the locking rod is inserted into the corresponding limit hole to lock the position of the adjustment plate.
[0020] Step 3: During the use of the shock absorber, when the road conditions change, the piston plate slides inside the cylinder, the piston rod moves the limit plate, the return spring assists in shock absorption, the pressure sensor detects the pressure changes in the upper and lower chambers inside the cylinder, the acceleration sensor detects the acceleration of the piston rod, and the displacement sensor detects the displacement of the piston plate. The detected data is fed back to the external control system. After the control system judges the road conditions, it controls the servo motor to start, and the adjustment plate rotates accordingly, so that the adjustment holes of different diameters connect the oil inlet pipe and the oil outlet pipe, the hydraulic oil flow speed changes, and the damping force is adjusted in real time.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This utility model, by setting up an intelligent speed regulation mechanism, utilizes pressure sensors, acceleration sensors, and displacement sensors to monitor the working status of the shock absorber in real time. It detects pressure changes inside the cylinder, the acceleration and displacement of the piston plate, and feeds the data back to the external control system. This allows the system to determine the road conditions and motion state of the vehicle, and adjusts the damping based on the detected values. When damping force adjustment is needed, the servo motor starts, driving the adjustment shaft and adjustment disc to rotate through the meshing transmission of the worm and worm wheel and the meshing transmission of the spur gear. This allows the adjustment holes of different diameters to... The inlet and outlet oil pipes are connected, and the meshing structure of the worm gear and worm wheel has a self-locking characteristic, which can effectively prevent the adjusting shaft from rotating unexpectedly due to external vibrations or other factors when it is not driven. This ensures that the adjusting hole on the adjusting plate is always precisely aligned with the inlet and outlet oil pipes, thereby guaranteeing the stability and accuracy of the damping force adjustment. Because the flow speed of the hydraulic oil changes due to the different diameters of the adjusting holes, the damping force can be adjusted in real time and accurately, realizing speed regulation. This solves the problem that the existing shock absorber damping adjustment function is relatively simple and cannot perform speed regulation in real time and accurately according to the actual motion state.
[0023] 2. This utility model, by setting up a first adjustment and installation mechanism and a second adjustment and installation mechanism, facilitates the flexible installation of the shock absorber on different vehicles. By rotating the rotating cap, the rotating rod and the first bevel gear can be driven to rotate. Under the action of the electromagnetic clutch, it can selectively engage with the second bevel gear to drive the threaded rod to rotate, thereby allowing the mounting plate to move along the limit rod and adjust the position of the lifting lug. The electromagnetic clutch can lock the adjusted position to ensure the stability of the installation, enhance the versatility of the shock absorber, adapt to different installation needs, and improve the convenience and adaptability of installation.
[0024] 3. This utility model, by setting a spring force adjustment and locking mechanism, can adjust the spring force of the return spring according to actual usage needs. During adjustment, first pull the pull ring. The pull ring drives the pull rod and the moving plate to slide in the groove. While the moving plate compresses the limit spring, it causes the locking rod to disengage from the current limit hole, releasing the lock on the moving ring and the adjustment plate. Then, rotate the adjustment plate, which can drive the rotating sleeve and the moving ring to move along the threaded groove, changing the compression of the return spring, thereby adjusting the spring force. When adjusted to the appropriate position, release the pull ring. The limit spring loses pressure and pushes the moving plate to reset. The moving plate drives the locking rod to re-lock into the corresponding limit hole, thereby locking the position of the adjustment plate and preventing it from shifting during the operation of the shock absorber. This makes the spring force adjustment of the shock absorber more flexible and can be combined with changes in damping force to further optimize the shock absorption effect, improve the overall shock absorption performance and application range.

[0035] 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.
[0036] like Figure 1 - Figure 9 As shown, the present invention provides a technical solution: a novel real-time speed-adjustable shock absorber, including a cylinder 1, a piston plate 2 slidably connected inside the cylinder 1, a piston rod 3 fixedly connected to the top of the piston plate 2, the top end of the piston rod 3 penetrating the cylinder 1 and fixedly connected to a limit plate 4, a reset spring 7 sleeved on the outer surface of the cylinder 1, and an intelligent speed-adjusting mechanism 9 provided on the outer surface of the cylinder 1.
[0037] The intelligent speed control mechanism 9 includes a fixed cylinder 901, a mounting base 902, an adjusting shaft 903, a rotating shaft 904, an oil inlet pipe 907, an oil outlet pipe 908, and a servo motor 910. An adjusting disc 905 is fixedly connected to the top of the adjusting shaft 903. Multiple adjusting holes 906 with different diameters are opened on the top of the adjusting disc 905. One end of the oil inlet pipe 907 contacts the bottom of the adjusting disc 905, and the other end of the oil inlet pipe 907 passes through the fixed cylinder 901 and communicates with the interior of the cylinder body 1. One end of the oil outlet pipe 908 contacts the top of the adjusting disc 905. The other end of 08 passes through the fixed cylinder 901 and is connected to the interior of the cylinder 1. The oil inlet pipe 907 is connected to the oil outlet pipe 908 through one of the adjustment holes 906. Two spur gears 909 are fixedly sleeved on the outer surface of the adjusting shaft 903 and the rotating shaft 904. The output end of the servo motor 910 passes through the fixed cylinder 901 and is fixedly connected to the worm gear 911. The outer surface of the rotating shaft 904 is fixedly sleeved with a worm wheel 912. Two pressure sensors 913 are installed at the inner top and inner bottom of the cylinder 1. An acceleration sensor 914 is installed on the top of the piston plate 2. A displacement sensor 915 is installed on the piston rod 3.
[0038] like Figure 1 , Figure 5 and Figure 9 As shown, a fixed cylinder 901 is fixedly connected to the outer surface of the cylinder 1, a mounting base 902 is fixedly connected inside the fixed cylinder 901, an adjusting shaft 903 and a rotating shaft 904 are rotatably connected to the top of the mounting base 902, an oil inlet pipe 907 and an oil outlet pipe 908 are fixedly installed inside the cylinder 1, a servo motor 910 is fixedly installed at one end of the fixed cylinder 901, two spur gears 909 are meshed, a worm gear 911 and a worm wheel 912 are meshed, a first adjusting mounting mechanism 5 is provided on the top of the limiting plate 4, and a second adjusting mounting mechanism 6 is provided on the bottom of the cylinder 1. The first adjusting mounting mechanism 5 and the second adjusting mounting mechanism 6 have the same structure. The second adjusting mounting mechanism 6 includes a fixed shell 601 fixedly connected to the bottom of the cylinder 1, and the fixed cylinder 901 serves as the intelligent speed adjustment mechanism 9. Each component provides a stable mounting platform. The mounting base 902 ensures the stability of the adjusting shaft 903 and rotating shaft 904 during rotation, guaranteeing the accuracy of transmission. The fixed setting of the oil inlet pipe 907 and oil outlet pipe 908 ensures the stability of the hydraulic oil flow path, avoiding the impact of shaking on oil transmission. The fixed installation of the servo motor 910 ensures the stability of power output. The meshing connection of the two spur gears 909 and the worm gear 911 and worm wheel 912 realizes the efficient transmission of power, making the rotation of the adjusting shaft 903 and adjusting disc 905 smoother. The first adjusting mounting mechanism 5 and the second adjusting mounting mechanism 6 have the same structure, which facilitates manufacturing and maintenance. The fixed shell 601 provides the mounting base for each component of the second adjusting mounting mechanism 6, improving the overall stability of the shock absorber structure.
[0039] like Figure 5 As shown, a lifting lug 602 is provided inside the fixed housing 601, and the lifting lug 602 passes through the fixed housing 601. Two support frames 603 are fixedly connected inside the fixed housing 601. A threaded rod 604 is rotatably connected to the inner side of one support frame 603, and a limit rod 605 is fixedly connected to the inner side of the other support frame 603. An mounting plate 606 is threaded onto the outer surface of the threaded rod 604 and the limit rod 605. The lifting lug 602 is installed at the bottom of the mounting plate 606, providing a connection point for the installation of the shock absorber, facilitating connection with vehicles and other equipment. The two support frames 603 provide stable support for the threaded rod 604 and the limit rod 605, ensuring that they will not shift during operation. When the threaded rod 604 rotates, the mounting plate 606 can move stably along the limit rod 605, ensuring the smoothness of the adjustment of the lifting lug 602 position, avoiding jamming or tilting during the adjustment process, making the adjustment of the lifting lug 602 position more precise, and further enhancing the adaptability of the installation.
[0040] like Figure 5 As shown, a rotating rod 607 is connected to the inner side of one of the support frames 603 via a bearing. One end of the rotating rod 607 is fixedly connected to a first bevel gear 608, and the smooth end of the threaded rod 604 is fixedly connected to a second bevel gear 609. The bearing connection makes the rotation of the rotating rod 607 smoother and reduces the wear caused by friction. The meshing transmission of the first bevel gear 608 and the second bevel gear 609 converts the horizontal rotation of the rotating rod 607 into the vertical rotation of the threaded rod 604, realizing the change of power direction. This makes it easier to drive the threaded rod 604 to rotate by rotating the rotating rod 607, thereby moving the mounting plate 606 and making the adjustment of the position of the lifting lug 602 easier and more convenient.
[0041] like Figure 5 As shown, a fixing rod 610 is fixedly connected to the inner top of one of the support frames 603, and an electromagnetic clutch 611 is installed on the inner side of one of the support frames 603. The input end of the electromagnetic clutch 611 is fixedly connected to the bottom end of the fixing rod 610, and the output end of the electromagnetic clutch 611 is fixedly connected to a third bevel gear 612. The fixing rod 610 provides stable installation support for the electromagnetic clutch 611. The electromagnetic clutch 611 can control the meshing state of the third bevel gear 612 and the first bevel gear 608. When it is necessary to lock the position of the lifting lug 602, the electromagnetic clutch 611 engages, restricting the rotation of the first bevel gear 608, thereby locking the position of the threaded rod 604 and the mounting plate 606, ensuring that the lifting lug 602 will not be displaced due to vibration or other factors after installation, thus enhancing the stability of the installation.
[0042] like Figure 2 and Figure 5As shown, the second bevel gear 609 and the third bevel gear 612 are respectively meshed with the first bevel gear 608. A support plate 613 is fixedly connected to the inner side of one of the support frames 603. The smooth end of the threaded rod 604 moves through the support plate 613. One end of the rotating rod 607 moves through the fixed shell 601 and is equipped with a rotating cap 614. An elastic adjustment and locking mechanism 8 is provided on the outer surface of the cylinder 1. The elastic adjustment and locking mechanism 8 includes a threaded groove 801 opened on the outer surface of the cylinder 1. Through the meshing of the second bevel gear 609, the third bevel gear 612 and the first bevel gear 608, the power transmission and locking functions are switched, making the position adjustment and locking of the lifting lug 602 more flexible. The support plate 613 provides auxiliary support for the threaded rod 604, further enhancing its stability during rotation. The rotating cap 614 facilitates the operator to rotate the rotating rod 607, improving the convenience of operation. The threaded groove 801 provides a track for the movement of the adjustment plate 802.
[0043] like Figure 2 , Figure 3 and Figure 6 As shown, an adjusting plate 802 is threadedly connected to the outer surface of the threaded groove 801. A movable ring 803 is sleeved on the outer surface of the cylinder 1. A rotating sleeve 804 is rotatably mounted on the top of the movable ring 803. The top of the rotating sleeve 804 is fixedly connected to the adjusting plate 802. Two sliding grooves 805 are opened on the outer surface of the cylinder 1. Two sliders 806 are slidably connected in the two sliding grooves 805. The two sliders 806 are fixedly connected to the inner surface of the movable ring 803. Through the threaded connection between the adjusting plate 802 and the threaded groove 801, the adjusting plate 802 can move along the axial direction of the cylinder 1 when the rotating sleeve 804 is rotated, thereby changing the compression of the return spring 7. The rotatable connection between the movable ring 803 and the rotating sleeve 804 allows the movable ring 803 to move synchronously with the adjusting plate 802 when the rotating sleeve 804 rotates. The sliding of the sliders 806 in the sliding grooves 805 guides and limits the movement of the movable ring 803, preventing the movable ring 803 from rotating or deviating, and ensuring the smooth movement of the adjusting plate 802.
[0044] like Figure 6 , Figure 7 and Figure 8 As shown, the outer surface of the cylinder 1 is provided with multiple limiting holes 807. The bottom of the moving ring 803 is fixedly connected to an L-shaped frame 808. The inner side of the L-shaped frame 808 is provided with a groove 809. A moving plate 810 is slidably connected in the groove 809. The multiple limiting holes 807 provide multiple locking positions for the locking rod 811 to meet the needs of different elastic force adjustment. The L-shaped frame 808 provides installation space for components such as the moving plate 810. The groove 809 guides the sliding of the moving plate 810, ensuring that the moving plate 810 can move smoothly and that the locking rod 811 can accurately engage or disengage from the limiting holes 807.
[0045] like Figure 7 and Figure 8 As shown, a locking rod 811 is fixedly connected to one side of the movable plate 810, and a pull rod 812 is fixedly connected to the other side of the movable plate 810. A limiting spring 813 is sleeved on the outer surface of the pull rod 812. One end of the pull rod 812 movably passes through the L-shaped frame 808 and is fixedly connected to a pull ring 814. One end of the locking rod 811 is inserted into one of the limiting holes 807. By locking the locking rod 811 into the limiting hole 807, the position of the movable ring 803 and the adjusting plate 802 can be effectively locked, preventing them from moving when the shock absorber is working. The pull rod 812 and the pull ring 814 make it easy for the operator to pull the movable plate 810 to separate the locking rod 811 from the limiting hole 807. The limiting spring 813 can automatically push the movable plate 810 and the locking rod 811 back to their original positions after the pull ring 814 is released, ensuring that the locking rod 811 can be firmly locked into the limiting hole 807, enhancing the locking effect after spring adjustment and making spring adjustment more reliable.
[0046] The usage and working principle of this device are as follows: During the installation phase, the shock absorber is installed on the vehicle through the first adjusting installation mechanism 5 and the second adjusting installation mechanism 6. According to the installation requirements, the electromagnetic clutch 611 is disengaged, and the first bevel gear 608 is no longer restricted by the third bevel gear 612 and can rotate freely. Rotating the rotating cap 614 drives the rotating rod 607 and the first bevel gear 608 to rotate. The first bevel gear 608 meshes with the second bevel gear 609, causing the threaded rod 604 to rotate. The mounting plate 606 moves along the limiting rod 605. The lifting lug 602 is adjusted to a suitable position. After the position is determined, the electromagnetic clutch 611 is engaged to lock the position of the threaded rod 604, completing the installation.
[0047] During the elasticity adjustment stage, when it is necessary to adjust the elasticity of the reset spring 7, pull the pull ring 814, and pull rod 812 drives the moving plate 810 to slide in the groove 809, compressing the limit spring 813, causing the locking rod 811 to disengage from the limit hole 807. Then rotate the adjusting plate 802, causing the rotating sleeve 804 to move along the threaded groove 801, and the moving ring 803 to move with the rotating sleeve 804. The slider 806 slides and guides in the sliding groove 805. After adjusting to the appropriate elasticity, release the pull ring 814, the limit spring 813 pushes the moving plate 810 to reset, and the locking rod 811 engages with the corresponding limit hole 807, locking the position of the adjusting plate 802.
[0048] During the use of the shock absorber, the shock absorber automatically adjusts its damping. When the road conditions change, the piston plate 2 slides inside the cylinder 1, the piston rod 3 moves the limit plate 4, the return spring 7 assists in damping, the pressure sensor 913 detects the pressure changes in the upper and lower chambers of the cylinder 1, the acceleration sensor 914 detects the acceleration of the piston plate 2, and the displacement sensor 915 detects the displacement of the piston rod 3. The detected data is fed back to the external control system. After the control system judges the road conditions, it controls the servo motor 910 to start, the worm gear 911 and the worm wheel 912 mesh and drive, the rotating shaft 904 drives the adjusting shaft 903 to rotate through the spur gear 909, and the adjusting disc 905 rotates accordingly, so that the adjusting holes 906 of different diameters connect the oil inlet pipe 907 and the oil outlet pipe 908. Due to the different diameters of the adjusting holes 906, the hydraulic oil flow speed changes, and the damping force is adjusted in real time.
