DETAILED DESCRIPTION

[0026] like Figures 1 to 5 As shown, the present invention discloses a shock absorber bracket for a new energy vehicle, comprising a body support 1, a chassis support 2, a first connecting rod 3, a second connecting rod 4, a shock absorber body 5, a damping buffer 6, and a buffer connector 7. The body support 1 and the chassis support 2 are respectively connected to the body and chassis of the vehicle, the first connecting rod 3 and the second connecting rod 4 are respectively hinged to the body support 1 and the chassis support 2 at both ends, the first connecting rod 3 and the second connecting rod 4 are parallel to each other, the damping buffer 6 and the shock absorber body 5 are respectively hinged to the first connecting rod 3 and the second connecting rod 4 at both ends; the shapes of the body support 1 and the chassis support 2 can be adjusted according to actual conditions.

[0027] The working principle and process of the present invention application are as follows:

[0028] The body mount 1 and chassis mount 2 are hinged at two points to the first link 3 and second link 4, respectively. Together, these four components form a parallelogram linkage. The shock absorber body 5 utilizes an existing structure, with its ends mounted on the first link 3 and second link 4. It primarily absorbs and mitigates vibrations caused by road irregularities, enhancing ride comfort. When additional vibrations are transmitted to the first and second links 3 and 4, the damping element 6 reduces the vibrations of the mount itself, further enhancing vehicle comfort.

[0029] The damping buffer component 6 disclosed in the present invention includes an outer tube 8, a first plug 9, a first pin 10, a second plug 11, a second pin 12, and a first spring 13. The outer tube 8 is generally cylindrical and is connected to the shock absorber body 5 via a buffer connector 7, which can predetermine the basic position of the outer tube 8. One end of the first plug 9 is hinged to the first connecting rod 3 via the first pin 10, and the other end of the first plug 9 is inserted into one end of the outer tube 8 in a sliding and sealing manner. Similar to the first plug 9, one end of the second plug 11 is hinged to the second connecting rod 4 via the second pin 12, and the other end of the second plug 11 is inserted into the other end of the outer tube 8 in a sliding and sealing manner. The outer tube 8 is filled with damping fluid. A first spring 13 is connected between the first plug 9 and the second plug 11 to provide elastic restoring force for the first plug 9 and the second plug 11.

[0030] The present invention utilizes a damping buffer 6 installed between the first and second connecting rods 3 and 4. The damping of the first and second connecting rods 3 and 4's own vibrations is also achieved through the relative movement between the first and second plug posts 9 and 11 of the damping buffer 6. The outer cylinder 8 is connected to the shock absorber body 5 via the buffer connector 7. The relative distance between the first and second connecting rods 3 and 4 is then used to translate the movement of the plug posts, thus stabilizing the overall operation of the bracket. The direction of vibration reduction is primarily along the length of the first and second connecting rods 3 and 4.

[0031] Vibration reduction can also be achieved for the normal vibration of the first connecting rod 3 and the second connecting rod 4. Specifically, a first sliding hole 14 is defined at the end of the first plug 9 located within the outer tube 8, and a second sliding hole 15 is defined at the end of the second plug 11 located within the outer tube 8. A transition tube 16 is sealed and slidably disposed within both the first and second sliding holes 14, 15. Transition tube 16 is coaxially secured to the inner side of the outer tube 8 via an intermediate plate 17. In this embodiment, an axially extending damping hole is defined in the intermediate plate 17, providing a buffer when damping fluid flows through the damping hole.

[0032] The transition tube 16 is filled with damping fluid. A first piston 18 is slidably mounted on one end of the transition tube 16. The first piston 18 is connected to a first roller 20 via a first support rod 19. A second spring 21 is connected between the first piston 18 and the first plug 9. A first cam 22 corresponding to the first roller 20 is mounted on the first pin 10. A second piston 23 is slidably mounted on the other end of the transition tube 16. The second piston 23 is connected to a second roller 25 via a second support rod 24. A third spring 26 is connected between the second piston 23 and the second plug 11. A second cam 27 corresponding to the second roller 25 is mounted on the second pin 12. To prevent the pin from falling off the plug, a stopper can be provided at the end, and an elastic recovery device can be installed between the pin and the connecting rod to restore the normal position of the plug to its original position.

[0033] Taking the first pin 10 as an example, the normal vibration on the first connecting rod 3 can be transmitted to the first pin 10, allowing the first pin 10 to displace along its own axial direction. The first cam 22 on the first pin 10 can act on the first roller 20, allowing the first roller 20 to drive the first piston 18 to displace via the first support rod 19, thereby compressing the damping fluid in the transition tube 16 and providing a damping and buffering effect. Of course, the second pin 12 functions in a similar manner to the first pin 10. With the coordinated action of the two pins, they can be used to reduce the normal vibration on the first connecting rod 3 and the second connecting rod 4. Since the first piston 18 and the second piston 23 are located at opposite ends of the transition tube 16, the vibrations between the two pistons can also partially offset each other, improving the vibration reduction capability.

[0034] In this embodiment, piston holes 28 are formed at both ends of the transition tube 16, respectively, for engaging the first piston 18 and the second piston 23. A central hole 29 is formed in the middle of the transition tube 16, connecting the piston holes 28 at both ends. The diameter of the central hole 29 is smaller than that of the piston holes 28. When the piston compresses the piston holes 28, the damping fluid is compressed into the smaller diameter central hole 29, making the damping fluid flow in the central hole 29 more sensitive and improving the cushioning capacity.

[0035] In this embodiment, the buffer connector 7 includes a first clamp 30, a second clamp 31 and a hinge plate 32. The first clamp 30 is sleeved on the outside of the shock absorber body 5, but cannot interfere with the shock absorber spring. The second clamp 31 is sleeved on the outside of the outer tube 8. The first clamp 30 and the second clamp 31 are hinged by the hinge plate 32, which can adapt to the changes in the distance and angle between the shock absorber body 5 and the outer tube 8 to a certain extent, making it convenient for the installation of the two.

[0036] In this embodiment, a slot 33 is formed on the second connecting rod 4, and the second pin 12 is slidably disposed in the slot 33. The second pin 12 is secured to the second connecting rod 4 by a locking member 34. The hinge position of the second pin 12 can be adjusted along the slot 33, creating a suitable phase difference between the second pin 12 and the first pin 10, thereby more easily offsetting vibrations. The second pin 12 is then locked by the locking member 34 to prevent it from sliding during operation.

[0037] In this embodiment, a first damping cylinder 35 is connected between the first connecting rod 3 and the vehicle body support 1, and the first damping cylinder 35 is arranged along the normal direction of the first connecting rod 3. A second damping cylinder 36 is connected between the second connecting rod 4 and the chassis support 2, and the second damping cylinder 36 is arranged along the normal direction of the second connecting rod 4. The structure and installation method of the first damping cylinder 35 and the second damping cylinder 36 are identical. Taking the first damping cylinder 35 as an example, the first damping cylinder 35 is mounted outside the hinge axis between the first connecting rod 3 and the vehicle body support 1, which can buffer the vibration of the vehicle body support 1, allowing vibrations on the vehicle body support 1 to be more easily transmitted to the part without the second connecting rod 4. Similarly, the second damping cylinder 36 is mounted outside the hinge axis between the second connecting rod 4 and the chassis support 2, which can buffer the vibration of the chassis support 2, allowing vibrations on the chassis support 2 to be more easily transmitted to the part without the first connecting rod 3. Therefore, the vibrations on the first link 3 and the second link 4 are mainly transmitted through the chassis support 2 and the body support 1 respectively. After the two are offset in phase, they are damped and buffered by the damping buffer 6, which can achieve a better vibration reduction effect.

[0038] In this embodiment, a damping chamber 37 is formed inside the first damping cylinder 35. An annular damping groove 38 is formed on the surface of the first connecting rod 3. A through hole 39 is formed on the first connecting rod 3, connecting the damping chamber 37 and the damping groove 38. A damping plate 40 is mounted within the damping groove 38, and the damping plate 40 has damping holes formed therein. The damping fluid filled in the damping groove 38 can buffer the vibrations of the first connecting rod 3 and the second connecting rod 4. When the first damping cylinder 35 is compressed by vibration, the damping fluid in the first damping cylinder 35 can be compressed from the through hole 39 into the damping groove 38, and then pass through the damping holes in each damping plate 40 to reduce vibration.

[0039] In this embodiment, the opening of the damping groove 38 is closed by a sealing plate 41 . The sealing plate 41 is provided with a connecting hole 42 connected to the first connecting rod 3 , which can facilitate cleaning of impurities in the damping groove 38 .

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
