Description

[Detailed Description of the Invention] This invention relates to a shock absorbing device for a vehicle, particularly a truck bed.

Conventionally, in the case of a truck loading platform, the vertical joists that support the platform and the frame were simply fixed by bolts, etc. via a connecting material, but vibration and noise were generated in this area, or when the width was increased. This caused problems when transporting easily damaged items or transporting personnel.

This invention aims to improve the above-mentioned defects by interposing a cushioning material between the vertical joists of the loading platform and the frame, and by incorporating stoppers at various locations to optimize the amount of deflection of the cushioning material. By inserting a cushioning material (rubber) into the part, the generation of noise due to the impact of the stopper is prevented, and the shock input to the loading platform is reduced, and the absorption of vibrations, noise, etc. is also taken into consideration.

To further explain this invention with reference to an embodiment shown in the drawings, FIG. 1 is a perspective view of an embodiment of this invention.
In the figure, the XX direction is the longitudinal direction of the vehicle, and is indicated by a dotted line. A is the loading platform, B is the vertical joist of the loading platform, and C is the frame. This device is sandwiched between the vertical joist B and the frame C. Multiple units are arranged on the frame to evenly distribute the load on the platform. Reference numeral 1 denotes a lid body, and a bracket 2 is fixed to the front and rear sides of the lid body 1, and is fixed to a vertical joist B through a hole 8 on the bracket 2 by bolting. 6 is a box with cushioning elastic material inside,
For example, the cushion rubber 7 is accommodated, and the bottom hole 8
The box body 6 is fixed to the frame C by inserting studs into the studs and screwing nuts into the studs from the frame side (FIG. 3). Reference numeral 3 designates an upper stopper having a hole 8' in its upper part and a lower part curved in the shape of a shape, into which the extended part of the lid 1 is fitted and welded together with the extended part 1' of its side wall. The upper stopper 3 is fixed to the side surface of the vertical joist B by means of the upper hole 8', for example, by bolting. 5 is a lower stopper, which has a curved part that fits from the outside into the curved part of the upper stopper 3, and is fixed to the side surface of the frame C by tightening bolts through a hole 8'' provided in the lower extension leg 5''. be done. 5' is a reinforcing side plate. The curved part of the upper stopper 3 is held together with the lid 1 in the curved part of the lower stopper 5. A cushioning material 4 is interposed between the fitting curved portions of the upper and lower stoppers 3 and 5.

Note that the box body 6 only needs to be capable of supporting the cushioning material 7, and has a side wall at least in the front-rear direction (X-X direction in FIG. , a buffer material 7' is interposed.

Since this device has the above-mentioned configuration, when the cargo is loaded on the cargo platform and the vehicle is operated, the vibration of the cargo platform and the vehicle platform is alleviated in the vertical direction by the upper and lower surfaces of the curved portions of the upper and lower stoppers and the cushioning material 7. In addition, excessive movement is restricted in the front-rear direction by the side plate 1' of the lid body 1 and the side plate of the box body 6, and the left-right direction can be similarly restricted by the shock absorbers arranged in pairs. In addition, since the cushioning material and the stopper are combined as a pair, it is possible to suppress excessive deflection of the cushioning material, improve the durability of the cushioning material, and improve the running stability of the vehicle. It is something that can be expected.

Furthermore, the cushioning effect can be further improved by the cushioning material interposed between the box body, the lid body, and the upper and lower stoppers.
