[0017] A method for using a novel speed-changing real-time adjustable shock absorber includes the following methods:

[0018] Step 1: During the installation operation phase, the shock absorber is installed on the vehicle through the first adjustment and installation mechanism and the second adjustment and installation mechanism. According to the installation requirements, the electromagnetic clutch is disconnected, the rotating cap is turned to rotate the rotating rod and the first bevel gear. The first bevel gear and the second bevel gear are engaged and driven to rotate the threaded rod. The mounting plate moves along the limit rod and the lifting lug is adjusted to the appropriate position. After the position is determined, the electromagnetic clutch is connected to lock the position of the threaded rod to complete the installation.

[0019] Step 2: Elastic force adjustment stage: when the elastic force of the reset spring needs to be adjusted, pull the pull ring to drive the movable plate to slide in the groove, compress the limit spring, and make the clamping rod disengage from the limit hole. Then, rotate the adjustment plate to make the rotating sleeve move along the threaded groove. The movable ring moves with the rotating sleeve, and the slider slides and guides in the slide groove. After adjusting to the appropriate elastic force, release the pull ring, the limit spring pushes the movable plate to reset, and the clamping rod is locked into the corresponding limit hole to lock the position of the adjustment plate.

[0020] Step 3: Shock absorber use stage.

After the control system judges the road conditions, it controls the servo motor to start, and the adjustment disk rotates accordingly, so that the adjustment holes of different diameters connect the oil inlet pipe and the oil outlet pipe, the hydraulic oil circulation speed changes, and the damping force is adjusted in real time.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention sets up an intelligent speed-changing adjustment mechanism, uses pressure sensors, acceleration sensors and displacement sensors to monitor the working status of the shock absorber in real time, detects the pressure changes inside the cylinder, the movement acceleration and displacement of the piston plate, and feeds the data back to the external control system, thereby judging the road conditions and movement status of the vehicle, and adjusting the damping according to the detected values. When the damping force needs to be adjusted, the servo motor starts, and the meshing transmission of the worm and worm wheel and the meshing transmission of the spur gear drives the adjustment shaft and the adjustment disk to rotate, so that the adjustment holes of different diameters are aligned with the inlet. The oil pipe and the oil outlet pipe are connected, and the meshing structure of the worm and the worm wheel has a self-locking feature, which can effectively prevent the adjusting shaft from accidentally rotating due to external vibrations and other factors in the non-driven state, ensuring that the adjusting hole on the adjusting disk is always precisely connected with the oil inlet pipe and the oil outlet pipe, thereby ensuring the stability and accuracy of the damping force adjustment. Due to the different diameters of the adjusting holes, the circulation speed of the hydraulic oil changes, thereby adjusting the damping force in real time and accurately to achieve variable speed adjustment, solving the problem that the damping adjustment function of the existing shock absorber is relatively single and cannot be adjusted in real time and accurately according to the actual motion state.

[0023] 2. The present invention provides a first adjustment mounting mechanism and a second adjustment mounting mechanism, which 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 be selected to engage with the second bevel gear to rotate the threaded rod, and then the mounting plate can be moved along the limit rod to adjust the position of the lifting ear. The setting of 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 requirements, and improve the convenience and adaptability of installation.

[0024] 3、The present application is provided with elastic force adjusting locking mechanism, can adjust the elastic force of reset spring according to actual use demand, when adjusting, pull the pull ring first, the pull ring drives the pull rod and the moving plate to slide in the groove, the moving plate compresses the limit spring at the same time, makes the clamping rod from the current limit hole, removes the locking of the moving ring and the adjusting plate, then rotates the adjusting plate, can drive the rotating sleeve and the moving ring to move along the thread groove, changes the compression amount of reset spring, thereby adjusts the elastic force, when adjusting to the appropriate position, loosen the pull ring, the limit spring loses the pressure and pushes the moving plate to reset, the moving plate drives the clamping rod to reinsert into the corresponding limit hole, and then locks the position of the adjusting plate, avoids the displacement of the shock absorber during the working process, facilitates the elastic force adjustment of the shock absorber to be more flexible, can cooperate the change of damping force to further optimize the damping effect, improves the overall damping performance and application range.

[0039] like Figure 5 As shown, a lifting ear 602 is provided in the fixed shell 601, and the lifting ear 602 passes through the fixed shell 601. Two support frames 603 are fixedly connected to the fixed shell 601, and the inner side of one of the support frames 603 is rotatably connected to a threaded rod 604, and the inner side of the other support frame 603 is fixedly connected to a limit rod 605. The outer surfaces of the threaded rod 604 and the limit rod 605 are threadedly mounted with a mounting plate 606, and the lifting ear 602 is mounted on the bottom of the mounting plate 606. The lifting ear 602 provides a connection point for the installation of the shock absorber, which is convenient for connection with vehicles and other equipment; the two support frames 603 provide stable support for the threaded rod 604 and the limit rod 605 to ensure that they will not deviate 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 position adjustment of the lifting ear 602, avoiding jamming or tilting during the adjustment process, making the position adjustment of the lifting ear 602 more accurate, and further enhancing the adaptability of the installation.

[0040] like Figure 5 As shown, the inner side of one of the support frames 603 is connected to a rotating rod 607 through 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 loss 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 the power direction, making it convenient to drive the threaded rod 604 to rotate by rotating the rotating rod 607, thereby driving the mounting plate 606 to move, making the adjustment of the position of the lifting ear 602 more labor-saving and convenient.

[0041] like Figure 5 As shown, the inner top of one of the support frames 603 is fixedly connected to a fixing rod 610, 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 the third bevel gear 612. The fixing rod 610 provides a 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 ear 602, the electromagnetic clutch 611 engages to limit the rotation of the first bevel gear 608, and then locks the position of the threaded rod 604 and the mounting plate 606, ensuring that the lifting ear 602 will not be displaced due to factors such as vibration after installation, thereby 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, and a support plate 613 is fixedly connected to the inner side of one of the support frames 603, and the smooth end of the threaded rod 604 is movably passed through the support plate 613, and one end of the rotating rod 607 is movably passed through the fixed shell 601 and is installed with a rotating cap 614. The outer surface of the cylinder 1 is provided with an elastic adjustment locking mechanism 8, and the elastic adjustment 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 function are switched, making the position adjustment and locking switching of the lifting ear 602 more flexible; the support plate 613 plays an auxiliary supporting role on the threaded rod 604, further enhancing its stability during rotation; the rotating cap 614 facilitates the operator to rotate the rotating rod 607, thereby 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 The outer surface of the threaded groove 801 is threadedly connected to an adjusting plate 802, and the outer surface of the cylinder 1 is sleeved with a moving ring 803. A rotating sleeve 804 is rotatably installed on the top of the moving ring 803, and the top of the rotating sleeve 804 is fixedly connected to the adjusting plate 802. The outer surface of the cylinder 1 is provided with two sliding grooves 805, and 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 moving ring 803. Through the threaded connection between the adjusting plate 802 and the threaded groove 801, when the rotating sleeve 804 is rotated, the adjusting plate 802 can move axially along the cylinder 1, thereby changing the compression amount of the reset spring 7; the rotating connection between the moving ring 803 and the rotating sleeve 804 allows the moving ring 803 to move synchronously with the adjusting plate 802 when the rotating sleeve 804 rotates; the sliding of the slider 806 in the sliding groove 805 guides and limits the movement of the moving ring 803, prevents the moving ring 803 from rotating or deflecting, and ensures the smooth movement of the adjusting plate 802.

[0044] like Figure 6 、 Figure 7 and Figure 8 As shown, a plurality of limiting holes 807 are provided on the outer surface of the cylinder 1, and an L-shaped frame 808 is fixedly connected to the bottom of the movable ring 803. A groove 809 is provided on the inner side of the L-shaped frame 808, and a movable plate 810 is slidably connected in the groove 809. A plurality of limiting holes 807 are used to provide a plurality of locking positions for the clamping rod 811 to meet the needs of different elastic force adjustments; the L-shaped frame 808 provides an installation space for components such as the movable plate 810; the groove 809 guides the sliding of the movable plate 810, ensuring that the movable plate 810 can move smoothly and ensuring that the clamping rod 811 can accurately engage with the limiting hole 807 or disengage from the limiting hole 807.

[0045] like Figure 7 and Figure 8 As shown, one side of the movable plate 810 is fixedly connected to a clamping rod 811, and the other side of the movable plate 810 is fixedly connected to a pull rod 812. The outer surface of the pull rod 812 is sleeved with a limit spring 813, and one end of the pull rod 812 is movable through the L-shaped frame 808 and fixedly connected to a pull ring 814. One end of the clamping rod 811 is clamped into one of the limit holes 807. By clamping the clamping rod 811 into the limit hole 807, the position of the movable ring 803 and the adjusting plate 802 can be effectively locked to prevent 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 clamping rod 811 from the limit hole 807; the limit spring 813 can automatically push the movable plate 810 and the clamping rod 811 to reset after loosening the pull ring 814, ensuring that the clamping rod 811 can be firmly clamped into the limit hole 807, thereby enhancing the locking effect after the elastic force is adjusted and making the elastic force adjustment more reliable.

[0046] The usage and working principle of this device: During the installation operation phase, the shock absorber is installed on the vehicle through the first adjustment and installation mechanism 5 and the second adjustment and installation mechanism 6. According to the installation requirements, the electromagnetic clutch 611 is disconnected, and the first bevel gear 608 loses the restriction of the third bevel gear 612 and can rotate freely. The rotating cap 614 is rotated to drive the rotating rod 607 and the first bevel gear 608 to rotate. The first bevel gear 608 and the second bevel gear 609 are engaged and transmitted to rotate the threaded rod 604. The mounting plate 606 moves along the limit rod 605, and the lifting ear 602 is adjusted to the appropriate position. After the position is determined, the electromagnetic clutch 611 is turned on to lock the position of the threaded rod 604 to complete the installation.

[0047] During the elastic force adjustment stage, when the elastic force of the reset spring 7 needs to be adjusted, pull the pull ring 814, and the pull rod 812 drives the movable plate 810 to slide in the groove 809, compressing the limit spring 813, so that the clamping rod 811 disengages from the limit hole 807, and then rotate the adjustment plate 802, so that the rotating sleeve 804 moves along the threaded groove 801, and the movable ring 803 moves with the rotating sleeve 804, and the slider 806 slides and guides in the slide groove 805. After adjusting to the appropriate elastic force, release the pull ring 814, and the limit spring 813 pushes the movable plate 810 to reset, and the clamping rod 811 is locked into the corresponding limit hole 807, locking the position of the adjustment plate 802.

[0048] During the use phase of the shock absorber, the shock absorber automatically adjusts the damping. When the road conditions change, the piston plate 2 slides in the cylinder 1, the piston rod 3 drives the limit plate 4 to move, and the return spring 7 assists in shock absorption. The pressure sensor 913 detects the pressure changes in the upper and lower chambers of the cylinder 1, the acceleration sensor 914 detects the movement acceleration of the piston plate 2, and the displacement sensor 915 detects the displacement of the piston rod 3, and feeds back the detected data to the external control system. After the control system judges the road conditions, it controls the servo motor 910 to start, the worm 911 and the worm wheel 912 to engage and transmit, the rotating shaft 904 drives the adjustment shaft 903 to rotate through the spur gear 909, and the adjustment disk 905 rotates accordingly, so that the adjustment holes 906 of different diameters are connected to the oil inlet pipe 907 and the oil outlet pipe 908. Due to the different diameters of the adjustment holes 906, the hydraulic oil circulation speed changes, and the damping force is adjusted in real time. At the same time, the self-locking characteristics of the worm 911 and the worm wheel 912 prevent the adjustment shaft 903 from rotating accidentally, ensuring accurate and stable adjustment.

[0049] The wiring diagram of the electromagnetic clutch 611, servo motor 910, pressure sensor 913, acceleration sensor 914 and displacement sensor 915 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring layout of the electromagnetic clutch 611, servo motor 910, pressure sensor 913, acceleration sensor 914 and displacement sensor 915 will not be explained in detail.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
