Description

Technical Field

[0001] This utility model belongs to the field of vehicle body component technology, specifically relating to a vehicle body vibration damping component. Background Technology

[0002] Trucks include dump trucks, tractor-trailers, off-road trucks for off-highway and roadless areas, and various vehicles manufactured for special needs. They transport goods by carrying cargo in a cargo box. In existing technologies, truck cargo boxes are mostly constructed of metal boxes with a cargo-bearing plate at the bottom, resulting in poor vibration damping performance. Therefore, our company has designed and proposed a cargo box vibration damping component. Utility Model Content

[0003] The purpose of this utility model is to provide a vibration damping component for a carriage. It has a simple structure and its bottom is similar to that of an ordinary carriage when in normal use. When vibration damping protection of the cargo is required, the vibration damping mechanism can be raised, and the weight of the cargo will not act on the lifting mechanism. It is highly practical and suitable for promotion.

[0004] This utility model provides the following technical solution: a car body vibration damping component, including a base plate, a strip-shaped mounting bracket fixedly provided on the lower surface of the base plate, the mounting bracket extending to the side of the base plate, a sliding rail with two through sides provided on the lower side of the mounting bracket, an inclined clamping groove provided on the side of the sliding rail at the side of the base plate, and a vibration damping seat provided at the inclined clamping groove;

[0005] The vibration damping seat is composed of a support cover on the upper side and a lower sliding plate on the lower side. The support cover and the lower sliding plate are fixedly connected by multiple spring columns. The support cover has an inclined sliding surface facing the inclined clamping groove. The top of the support cover is a flat plate.

[0006] A cylinder is fixedly installed at the bottom of the mounting bracket, and the output end of the cylinder is connected to the pull seat at the bottom of the lower slide plate.

[0007] Preferably, a support base is located below the base plate. The support base is fixed to the vehicle body. The support base has a recessed track groove at the mounting bracket. A first slide rail is provided at the lower slide plate location of the track groove. The lower slide plate is supported by the first slide rail. A second slide rail is provided at the pull seat location corresponding to the first slide rail.

[0008] Preferably, an upper plate is fixedly laid on the upper surface of the base plate, and the upper plate is provided with a friction surface.

[0009] Preferably, the upper surface of the lower slide rail is a plane, and when the plane plate is in contact with the plane of the lower slide rail, the spring column has a telescopic space, and the support cover is slidably connected to the side wall of the lower slide plate by a telescopic rod.

[0010] The beneficial effects of this utility model are: simple structure, the bottom is similar to a regular carriage during normal use, and the shock-absorbing mechanism can be raised when cargo vibration protection is needed, and the weight of the cargo will not act on the lifting mechanism. It is highly practical, as detailed below:

[0011] (1) This utility model is equipped with a vibration damping seat. When the flat plate of the vibration damping seat is on the lower slide rail, it lifts the bottom plate. When the vehicle is bumped, the support cover and the lower slide plate are squeezed, the spring column is squeezed and contracted, and the spring on it absorbs kinetic energy to dampen the vibration and protect the goods.

[0012] (2) This utility model is equipped with a support cover. When carrying normal goods, the bottom plate is supported by the support seat and the mounting frame is supported by the track groove. At this time, the pressure brought by the goods is supported by the support seat. When the vibration damping mechanism is needed, the cylinder runs and pulls the support cover to the inclined clamping groove. During this process, the inclined sliding surface pushes into the inclined clamping groove, lifts the bottom plate, and is supported by the spring column. When the flat plate lifts the bottom plate, the pressure brought by the goods is supported by the spring column. The drive mechanism is not affected by the pressure, and the bottom plate can select the support state according to different goods, thereby improving the service life of the vibration damping seat.

[0021] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] See Figure 1-2A vibration damping assembly for a vehicle compartment includes a base plate 1. An upper layer plate 2 is fixedly laid on the upper surface of the base plate 1. The upper layer plate 2 has a friction surface for supporting cargo. A strip-shaped mounting bracket 3 is fixedly installed on the lower surface of the base plate 1, extending to the side of the base plate 1. A sliding lower rail 5 with two through sides is provided on the lower side of the mounting bracket 3. An inclined clamping groove 6 is provided on the side of the sliding lower rail 5, and a vibration damping seat 4 is provided at the inclined clamping groove 6. The vibration damping seat 4 lifts the inclined clamping groove 6 and slides within the sliding lower rail 5, raising the base plate 1. The vibration damping seat 4 consists of a support cover 7 on the upper side and a sliding plate 10 on the lower side. The plates 10 are fixedly connected by multiple spring columns 11, which provide buffering and vibration reduction. The support cover 7 is provided with a sloping sliding surface 8 facing the sloping clamping groove 6. The sloping sliding surface 8 pushes open the sloping clamping groove 6. The top of the support cover 7 is a flat plate 9, and the upper surface of the lower slide rail 5 is flat. When the flat plate 9 is in contact with the plane of the lower slide rail 5, the spring column 11 has a telescopic space. The flat plate 9 is supported on the lower slide rail 5, so that the vibration damping seat 4 supports the bottom plate 1. The support cover 7 is slidably connected to the side wall of the lower slide plate 10 by a telescopic rod, which distributes the sloping force of the spring column 11 when the vibration damping seat 4 is squeezed into the lower slide rail 5.

[0023] See Figure 2-3 A cylinder 12 is fixedly installed at the bottom of the mounting bracket 3. The output end of the cylinder 12 is connected to the pull seat 13 at the bottom of the lower slide plate 10. The cylinder 12 drives the vibration damping seat 4 to move. Below the base plate 1 is a support seat 14, which is fixed to the vehicle body. The support seat 14 has a recessed track groove 15 corresponding to the mounting bracket 3, providing space for the mounting bracket 3. The track groove 15 has a first slide rail 16 at the lower slide plate 10, and the lower slide plate 10 is supported by the first slide rail 16. The first slide rail 16 has a second slide rail 17 corresponding to the pull seat 13, and the pull seat 13 slides along the second slide rail 17.

[0024] The vibration damping component of this utility model has a simple structure. Under normal use, the bottom is similar to that of an ordinary carriage. When vibration damping protection of the cargo is required, the vibration damping mechanism can be raised, and the weight of the cargo will not act on the lifting mechanism. It is highly practical and suitable for promotion.

[0025] For specific usage, please refer to... Figure 1-3When carrying normal cargo, the base plate 1 is supported by the support seat 14, and the mounting frame 3 is supported by the track groove 15. At this time, the pressure brought by the cargo is supported by the support seat 14. When the vibration damping mechanism is needed, the cylinder 12 operates and pulls the support cover 7 to move towards the inclined clamping groove 6. During this process, the inclined sliding surface 8 pushes into the inclined clamping groove 6, lifting the base plate 1 and supporting it through the spring column 11. When the flat plate 9 lifts the base plate 1, the pressure brought by the cargo is supported by the spring column 11. When the flat plate 9 of the vibration damping seat 4 pushes against the lower sliding rail 5, it lifts the base plate 1. When the vehicle is bumped, the support cover 7 and the lower sliding plate 10 are squeezed, and the spring column 11 is squeezed and contracted. The spring on it absorbs kinetic energy to dampen the vibration. The drive mechanism is not affected by the pressure. The base plate 1 can select the support state according to different cargo.
