Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a lower thrust rod bracket assembly with a buffer device. Background Technology

[0002] The lower thrust rod bracket assembly is a crucial "connection hub" and "force transmission node" in the rear suspension system of commercial vehicles. It reliably secures the lower thrust rod to the frame, ensuring effective power transmission, precise control of the rear axle position, and bearing enormous dynamic loads, playing a key role in the vehicle's driving performance, safety, and durability.

[0003] However, most lower thrust rod bracket assemblies currently lack effective protective measures, making them vulnerable to impacts from stones kicked up from the ground when the vehicle is in motion. Such impacts not only cause vibrations that affect the performance of the lower thrust rod bracket assembly, but also damage its surface. Utility Model Content

[0004] To address the technical problem that traditional lower thrust rod bracket assemblies are susceptible to structural damage from impacts by flying stones during driving, this utility model provides a lower thrust rod bracket assembly with a buffer device.

[0005] This utility model is implemented as follows: a lower thrust rod support assembly with a buffer device includes: a lower thrust rod support assembly body, on which a first clamping plate is provided; a second clamping plate is rotatably mounted on the first clamping plate via a hinge; and a buffer mechanism assembled on the second clamping plate for protecting the lower thrust rod support assembly body.

[0006] Preferably, the buffer mechanism includes: a U-shaped frame fixedly mounted on the second card plate, a support rod fixedly mounted on the U-shaped frame, a slider, a spring and a damping block slidably mounted on the support rod; a hinge rod hinged to the slider, one end of the hinge rod being hinged to a mounting plate, and a protective plate being provided on the mounting plate.

[0007] Preferably, the guard plate is arc-shaped and is fixedly mounted on the mounting plate by a second bolt.

[0008] Preferably, a T-shaped block is fixedly mounted on the mounting plate, and a housing is slidably mounted on the T-shaped block, with the top of the housing fixedly connected to the second card plate.

[0009] Preferably, the first card plate is fixedly mounted on the second card plate by a first bolt, and both the first bolt and the second bolt are made of stainless steel.

[0010] Preferably, a positioning block is fixedly installed on the first card plate, and the positioning block is adapted to the slot on the lower thrust rod bracket assembly.

[0011] Preferably, the hinge rod is inclined, and the spring is located between the slider and the damping block.

[0012] Compared with related technologies, the lower thrust rod support assembly with buffer device provided by this utility model has the following beneficial effects:

[0013] In this design, the use of hinges facilitates the installation of the first and second clamping plates onto the lower thrust rod support assembly. A buffer mechanism consisting of a U-shaped frame, support rod, slider, spring, damping block, hinge rod, mounting plate, and guard plate effectively blocks stones and objects launched from the ground, preventing damage to the surface of the lower thrust rod support assembly. When the guard plate is impacted, it pushes the mounting plate to transmit the impact force to the hinge rod, causing the hinge rod to push the slider along the support rod and compress the spring and damping block. The spring absorbs most of the impact energy first, and the remaining energy is dissipated by the damping block. Finally, the remaining impact energy is transmitted to the lower thrust rod support assembly through the U-shaped frame, effectively reducing the impact intensity and protecting the lower thrust rod support assembly from instantaneous impact damage, providing good protection.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a lower thrust rod support assembly with a buffer device, such as... Figure 1-5 As shown, the lower thrust rod bracket assembly with buffer device includes: a lower thrust rod bracket assembly body 1, on which a first clamping plate 2 is provided; a second clamping plate 4 rotatably mounted on the first clamping plate 2 via a hinge 3; and a buffer mechanism assembled on the second clamping plate 4 for protecting the lower thrust rod bracket assembly body 1.

[0023] In the design, when the vehicle is in motion, if the lower thrust rod bracket assembly is hit by a flying stone or other foreign object on the road, the buffer mechanism first absorbs the impact energy through its elastic deformation to reduce the impact energy. After the energy is weakened, the remaining impact energy is transmitted to the lower thrust rod bracket assembly body 1 through the second clamping plate 4. This can effectively protect the lower thrust rod bracket assembly body 1 from damage and significantly reduce the transmission of vibration to the vehicle frame.

[0024] In a further preferred embodiment of the present invention, the buffer mechanism includes: a U-shaped frame 5 fixedly installed on the second card plate 4, a support rod 6 fixedly installed on the U-shaped frame 5, a slider 7, a spring 8 and a damping block 9 slidably installed on the support rod 6; a hinge rod 10 hinged to the slider 7, one end of the hinge rod 10 being hinged to a mounting plate 16, and a protective plate 11 provided on the mounting plate 16.

[0025] In this embodiment, when the vehicle is impacted by the road surface during driving, flying stones or foreign objects first hit the guard plate 11, causing the guard plate 11 to move upward. The guard plate 11 will push the mounting plate 16 to transmit the impact force to the hinge rod 10, causing the hinge rod 10 to push the slider 7 to slide along the support rod 6 and compress the spring 8. At the same time, the damping block 9 can slow down the movement speed of the slider 7. The elastic deformation of the spring 8 absorbs part of the impact energy. Then the remaining impact energy will be absorbed and weakened by the damping block 9, thereby reducing the impact intensity transmitted to the U-shaped frame 5. This can effectively protect the entire lower thrust rod bracket body 1 from instantaneous impact damage, and the protection effect is good.

[0026] In a further preferred embodiment of the present invention, the guard plate 11 is configured as an arc shape, and the guard plate 11 is fixedly installed on the mounting plate 16 by a second bolt 15.

[0027] In this embodiment, the arc-shaped guard plate 11 can better protect the bottom of the lower thrust rod bracket assembly 1, effectively blocking the impact of stones.

[0028] In a further preferred embodiment of the present invention, a T-shaped block 12 is fixedly installed on the mounting plate 16, and a housing 13 is slidably installed on the T-shaped block 12. The top of the housing 13 is fixedly connected to the second card plate 4.

[0029] In this embodiment, the T-shaped block 12 and the housing 13 work together to ensure the stability of the mounting plate 16 and the protective plate 11 during use, preventing them from swaying left and right during use. When the protective plate 11 is hit, the protective plate 11 will push the T-shaped block 12 to slide vertically on the housing 13 through the mounting plate 16.

[0030] In a further preferred embodiment of the present invention, the first card plate 2 is fixedly mounted on the second card plate 4 by a first bolt 14, and both the first bolt 14 and the second bolt 15 are made of stainless steel.

[0031] In this embodiment, the first clamping plate 2 can be fixed on the second clamping plate 4 by using the first bolt 14 to prevent the first clamping plate 2 from rotating on the second clamping plate 4. When the first bolt 14 is removed, the first clamping plate 2 can rotate on the second clamping plate 4, thereby making it easy to remove the lower thrust rod bracket assembly 1 from the first clamping plate 2 and the second clamping plate 4.

[0032] In a further preferred embodiment of the present invention, a positioning block 17 is fixedly installed on the first card plate 2, and the positioning block 17 is adapted to the slot on the lower thrust rod bracket assembly body 1.

[0033] In this embodiment, the use of the positioning block 17 and the slot together can prevent the first card plate 2 and the second card plate 4 from sliding and rotating on the lower thrust rod bracket assembly 1, thus ensuring the stability of the first card plate 2 and the second card plate 4 on the lower thrust rod bracket assembly 1.

[0034] In a further preferred embodiment of this utility model, the hinge rod 10 is inclined, and the spring 8 is located between the slider 7 and the damping block 9.

[0035] In this embodiment, the arrangement of the spring 8 between the slider 7 and the damping block 9 forms a "series" buffer structure, so that the spring 8 absorbs most of the impact energy first, and the remaining energy is dissipated by the damping block 9.

[0036] In summary, compared with related technologies, this solution, through the use of hinge 3, facilitates the installation of the first clamping plate 2 and the second clamping plate 4 onto the lower thrust rod bracket assembly 1. The buffer mechanism, composed of a U-shaped frame 5, support rod 6, slider 7, spring 8, damping block 9, hinge rod 10, mounting plate 16, and guard plate 11, can block stones and objects bouncing from the ground, preventing damage to the surface of the lower thrust rod bracket assembly 1. When the guard plate 11 is impacted, it pushes the mounting plate 16 to transmit the impact force to the hinge rod 10, causing the hinge rod 10 to push the slider 7 along the support rod 6 and compress the spring 8 and damping block 9. The spring 8 absorbs most of the impact energy first, and the remaining energy is dissipated by the damping block 9. Finally, the remaining impact energy is transmitted to the lower thrust rod bracket assembly 1 through the U-shaped frame 5, effectively reducing the impact intensity and protecting the lower thrust rod bracket assembly 1 from instantaneous impact damage, resulting in better protection.
