Description

Technical Field

[0001] This utility model relates to the field of vibration damper technology, specifically to a magnetorheological vibration damper that is easy to install. Background Technology

[0002] Magnetorheological dampers (also known as magnetorheological dampers or magnetorheological energy dissipators) are high-precision technology products widely used in vibration control in various fields such as automotive suspension and seats, engineering construction, bridges, railways, and helicopters, achieving significant control effects. Especially in the automotive field, they can greatly improve vehicle stability, driving performance, and ride comfort.

[0003] Most existing magnetorheological vibration dampers are designed with upper and lower lifting rings, connected to their respective ends, to securely connect them to the device to be damped during installation. This installation process requires that the connecting shaft or rod of the device to be damped can pass unimpeded through the upper and lower lifting rings. However, if there are obstructions on the connecting shaft or rod, it will hinder the insertion of the upper and lower lifting rings, thus making the installation process of the magnetorheological vibration damper complicated and inconvenient. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an easy-to-install magnetorheological vibration damper, which can be easily installed on the device to be damped even if there are obstructing parts on the connecting shaft or connecting rod of the device to be damped.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetorheological vibration damper that is easy to install, comprising a magnetorheological vibration damper body, the magnetorheological vibration damper body including a vibration damper cylinder and a piston rod connected to the vibration damper cylinder, a first semicircular block being fixedly connected to the bottom of the vibration damper cylinder and the top of the piston rod respectively, a second semicircular block being rotatably connected to one end of the first semicircular block via a rotating shaft, and the other ends of the first semicircular block and the second semicircular block being connected by a fixing component.

[0006] Furthermore, the fixing assembly includes a first extension block connected to the end of the first semicircular block away from the rotating shaft and a second extension block connected to the end of the second semicircular block away from the rotating shaft. The first extension block has a first through hole, and the second extension block has a second through hole corresponding to the first through hole. The first extension block and the second extension block are fixed by bolts and nuts passing through the first through hole and the second through hole.

[0007] Furthermore, there are two of each of the first and second through holes, which are evenly distributed on the first and second extension blocks, respectively.

[0008] Furthermore, strip blocks are fixedly connected to both ends of the first extension block near the second extension block, and a matching strip groove is provided on the corresponding second extension block.

[0009] Furthermore, the width of the opening of the strip gradually increases from one end near the bottom of the groove to the other end.

[0010] Furthermore, a washer is fitted onto the bolt shank, with the washer positioned between the nut and the bolt head.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention features a first semicircular block fixedly connected to the bottom of the damper cylinder and the top of the piston rod, respectively. One end of the first semicircular block is rotatably connected to a second semicircular block via a rotating shaft, and the other ends of the first and second semicircular blocks are connected by a fixing assembly. The first and second semicircular blocks form a ring, facilitating connection to a connecting rod. By connecting the first and second semicircular blocks with one end rotatably via a rotating shaft and the other end via a fixing assembly, the ring formed by the first and second semicircular blocks can be opened when there are obstructing components on the connecting shaft or connecting rod of the device to be damped, thus facilitating the installation of the entire magnetorheological damper body onto the device to be damped.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1 to 3As shown, an easy-to-install magnetorheological vibration damper includes a magnetorheological vibration damper body 1. The magnetorheological vibration damper body 1 includes a vibration damper cylinder 2 and a piston rod 3 connected to the vibration damper cylinder 2. A first semicircular block 4 is fixedly connected to the bottom of the vibration damper cylinder 2 and the top of the piston rod 3, respectively. One end of the first semicircular block 4 is rotatably connected to a second semicircular block 6 through a rotating shaft 5. The other ends of the first semicircular block 4 and the second semicircular block 6 are connected by a fixing component 7.

[0019] Specifically, the first semicircular block 4 and the second semicircular block 6 form a ring. By setting one end of the first semicircular block 4 and the second semicircular block 6 to be rotatably connected through the rotating shaft 5 and the other end to be connected through the fixing component 7, when there are obstructing parts on the connecting shaft or connecting rod of the device to be damped, the ring formed by the first semicircular block 4 and the second semicircular block 6 can be opened, thereby facilitating the installation of the entire magnetorheological damper body 1 onto the device to be damped.

[0020] like Figures 1 to 3 As shown, the fixing component 7 includes a first extension block 8 connected to the end of the first semicircular block 4 away from the rotating shaft 5 and a second extension block 9 connected to the end of the second semicircular block 6 away from the rotating shaft 5. The first extension block 8 has a first through hole 10, and the second extension block 9 has a second through hole 11 corresponding to the first through hole 10. The first extension block 8 and the second extension block 9 are fixed by bolts 12 and nuts 13 passing through the first through hole 10 and the second through hole 11.

[0021] Specifically, a first extension block 8 is connected to the end of the first semicircular block 4 away from the rotating shaft 5, and a second extension block 9 is connected to the end of the second semicircular block 6 away from the rotating shaft 5. At the same time, a first through hole 10 and a second through hole 11 are respectively opened on the first extension block 8 and the second extension block 9, so that the first semicircular block 4 and the second semicircular block 6 can be fixed together by fixing the first extension block 8 and the second extension block 9. The first extension block 8 and the second extension block 9 are fixed by bolts 12 and nuts 13 passing through the first through hole 10 and the second through hole 11. The cooperation of bolts 12 and nuts 13 can firmly fix the first extension block 8 and the second extension block 9 together, and the bolts 12 and nuts 13 can also be easily removed, thereby facilitating the maintenance or replacement of the entire magnetorheological vibration damper body 1.

[0022] like Figure 1 and Figure 2 As shown, there are two of each of the first through hole 10 and the second through hole 11, which are evenly distributed on the first extension block 8 and the second extension block 9, respectively.

[0023] Specifically, by setting two of each of the first through hole 10 and the second through hole 11, the number of connection points can be increased, making the structure more robust during connection and improving the overall connection strength. By setting the first through hole 10 and the second through hole 11 to be evenly distributed on the first extension block 8 and the second extension block 9 respectively, it can be ensured that the entire structure is more uniformly stressed, avoiding stress concentration and thus enhancing the stability of the structure.

[0024] like Figure 2 and Figure 3 As shown, strip blocks 14 are fixedly connected to both ends of the first extension block 8 near the second extension block 9, and a matching strip groove 15 is provided on the corresponding second extension block 9.

[0025] Specifically, by setting the strip block 14 and the matching strip groove 15, the positions of the first extension block 8 and the second extension block 9 can be restricted, thereby restricting the positions of the first semicircular block 4 and the second semicircular block 6. This prevents the first semicircular block 4 and the second semicircular block 6 from skewing in the annular space after long-term use, thus improving the stability of the overall structure.

[0026] like Figure 2 and Figure 3 As shown, the width of the opening of the strip groove 15 gradually increases from one end near the bottom of the groove to the other end.

[0027] Specifically, by setting the width of the opening of the strip groove 15 to gradually increase from one end near the bottom of the groove to the other end, the strip block 14 can be stably inserted into the strip groove 15 when the first extension block 8 and the second extension block 9 are attached together, saving installation time.

[0028] like Figure 1 and Figure 2 As shown, a washer 16 is fitted onto the thread of bolt 12, and washer 16 is located between nut 13 and head of bolt 12.

[0029] Specifically, by attaching a washer 16 to the threaded rod of the bolt 12, the washer 16 can prevent the bolt 12 and nut 13 from loosening, thereby increasing the firmness of the connection between the bolt 12 and nut 13 and the first extension block 8 and the second extension block 9.

[0030] 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.
