Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an electrically controlled active shock absorber with adjustable damping. Background Art

[0002] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter out the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] Although traditional electronically controlled shock absorbers can be electronically extended and retracted to adapt to different road surfaces during use, the external shock absorbing spring is difficult to adjust, and therefore it is difficult to adjust to soft or hard road surfaces when driving on different road surfaces, affecting ride comfort. To address the above problems, the inventors propose an electronically controlled active shock absorber with adjustable damping to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a damping adjustable electrically controlled active shock absorber, comprising a cylinder body, an electrically controlled pressure rod is slidably installed on the top of the cylinder body, the top of the electrically controlled pressure rod is fixedly connected to a fixed cylinder, the middle position of the top of the fixed cylinder is fixedly connected to a connecting disk, a connecting ring is arranged on the outer side of the connecting disk, the bottom surface of the connecting ring is fixedly connected to the fixed cylinder, an adjusting disk is arranged on the middle part of the outer side of the fixed cylinder, a fixed disk is arranged on the bottom surface of the cylinder body, a connecting spring is arranged on the top surface of the fixed disk, a threaded sleeve is arranged on the upper part of the outer side of the fixed cylinder, a threaded sleeve is arranged on the outer side of the threaded sleeve, and the bottom end of the threaded sleeve is in contact with the top surface of the adjusting disk.

[0005] Preferably, the adjusting disk is slidably sleeved in the middle of the fixed cylinder, the top surface of the fixed disk is fixedly connected to the cylinder body, the bottom end of the connecting spring is fixedly connected to the fixed disk, the top end of the connecting spring is fixedly connected to the adjusting disk, and the threaded sleeve is fixedly sleeved in the upper part of the fixed cylinder.

[0006] Preferably, an upper connecting block is fixedly mounted on the top of the connecting disk, a lower connecting block is fixedly mounted on the bottom of the fixing disk, and a connecting groove is formed at one end of each of the lower connecting block and the upper connecting block.

[0007] Preferably, a limiting rod is slidably inserted between the connecting disk and the connecting ring, the bottom end of the limiting rod is fixedly connected to the threaded sleeve, and the top end of the limiting rod is fixedly connected to the limiting ring.

[0008] Preferably, a handle is fixedly connected to the outer side of the threaded sleeve.

[0009] Preferably, a protective ring gasket is fixedly connected to the bottom end of the fixing tube.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Through the cooperation of the threaded sleeve, the threaded sleeve column, the adjusting disk and the connecting spring, the connecting spring is pressed against by the fixed disk so that the adjusting disk moves to squeeze the connecting spring, thereby adjusting the extrusion state of the connecting spring. Then, the damping adjustment is realized by adapting the connecting spring through the electronically-controlled telescopic and electronically-controlled pressure rod, thereby better enabling the vehicle to take harder or softer measures in response to the road surface.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-3As shown, the utility model provides a technical solution: a damping adjustable electrically controlled active shock absorber, comprising an oil cylinder body 1, an electrically controlled pressure rod 11 is slidably mounted on the top of the oil cylinder body 1, a fixed cylinder 12 is fixedly connected to the top of the electrically controlled pressure rod 11, a connecting disk 13 is fixedly connected to the middle position of the top of the fixed cylinder 12, a connecting ring 14 is arranged on the outer side of the connecting disk 13, the bottom surface of the connecting ring 14 is fixedly connected to the fixed cylinder 12, an adjusting disk 15 is arranged on the middle part of the outer side of the fixed cylinder 12, a fixed disk 16 is arranged on the bottom surface of the oil cylinder body 1, a connecting spring 17 is arranged on the top surface of the fixed disk 16, a threaded sleeve 18 is arranged on the upper part of the outer side of the fixed cylinder 12, a threaded sleeve 19 is arranged on the outer thread of the threaded sleeve 18, and the bottom end of the threaded sleeve 19 contacts the top surface of the adjusting disk 15.

[0019] By adopting the above technical solution, the structural arrangement of the connecting disk 13 and the connecting ring 14 generates a circular groove between the connecting disk 13 and the connecting ring 14, in which the limiting rod 23 slides.

[0020] The adjusting disk 15 is slidably sleeved in the middle of the fixed cylinder 12, the top surface of the fixed disk 16 is fixedly connected to the cylinder body 1, the bottom end of the connecting spring 17 is fixedly connected to the fixed disk 16, the top end of the connecting spring 17 is fixedly connected to the adjusting disk 15, and the threaded sleeve 18 is fixedly sleeved on the upper part of the fixed cylinder 12.

[0021] An upper connecting block 20 is fixedly mounted on the top of the connecting plate 13 , and a lower connecting block 21 is fixedly mounted on the bottom of the fixing plate 16 . A connecting groove 22 is formed at one end of the lower connecting block 21 and the upper connecting block 20 .

[0022] By adopting the above technical solution, the upper connecting block 20 and the lower connecting block 21 are provided and the connecting groove 22 is opened, so that the device can be easily adapted and installed.

[0023] A limiting rod 23 is slidably inserted between the connecting plate 13 and the connecting ring 14 . The bottom end of the limiting rod 23 is fixedly connected to the threaded sleeve 19 , and the top end of the limiting rod 23 is fixedly connected to the limiting ring 24 .

[0024] By adopting the above technical solution, the limiting rod 23 and the limiting ring 24 cooperate with the rotation of the threaded sleeve 19 to limit the adjustment scale of the threaded sleeve 19, thereby preventing the threaded sleeve 19 from rotating and falling off on the threaded sleeve column 18.

[0025] A handle 25 is fixedly connected to the outer side of the threaded sleeve 19 .

[0026] By adopting the above technical solution, the handle 25 is provided to facilitate manual rotation of the handle 25 to control the threaded sleeve 19 .

[0027] A protective ring gasket 26 is fixedly connected to the bottom end of the fixed tube 12 .

[0028] By adopting the above technical solution, a protective ring gasket 26 is provided to prevent the electric control pressure rod 11 from driving the fixed cylinder 12 to move downward when it is extended into the cylinder body 1, thereby effectively preventing the fixed cylinder 12 from directly contacting the cylinder body 1 and causing damage to the cylinder body 1.

[0029] Working principle: First, install the device through the upper connecting block 20 and the lower connecting block 21. Then, when the damping needs to be adjusted, manually pull the handle 25 to rotate it. The handle 25 drives the threaded sleeve 19 to rotate. The rotation of the threaded sleeve 19 relies on the thread to move on the threaded sleeve 18, so that the threaded sleeve 19 slowly moves downward, and the threaded sleeve 19 moves to press against the adjusting disk 15 to move downward. The movement of the adjusting disk 15 drives the connecting spring 17 to move, and the connecting spring 17 is pressed against by the fixed disk 16 so that the adjusting disk 15 moves to squeeze the connecting spring 17, thereby adjusting the extrusion state of the connecting spring 17, and then the damping adjustment is realized by adapting the connecting spring 17 through the electrically-controlled telescopic and electrically-controlled pressure rod 11, so as to better enable the vehicle to take harder or softer measures in response to the road surface.
