Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
Example 1
As shown in fig. 1-5, an energy-absorbing curtain is a one-piece plate-shaped structure and is installed at the rear side of a wheel and below a mudguard. And the edge of the upper part of the curtain 1 is provided with an installation part 2 for connecting a mudguard. An energy absorption structure 6 is arranged below the mounting part 2 of the stop curtain 1, the energy absorption structure 6 can elastically stretch along the vertical direction, and a certain folding displacement space is formed in the front-back direction. In the driving process, the energy absorption structure of the stop curtain has an energy absorption effect on impact force when encountering stones and obstacles on a road, and the stop curtain and the fender are effectively protected from being damaged.
In order to facilitate positioning and reliable connection, the side surface of the connecting column 3 is connected with a reinforcing rib 4. Preferably, four reinforcing ribs 4 extending in the radial direction are uniformly arranged along the connecting column, and a square frame 5 is surrounded at the outer ends of the four reinforcing ribs 4.
The energy absorption structure 6 and the stop curtain 1 are integrally processed and formed, are arranged on the upper portion of the stop curtain 1 and are arranged in a penetrating mode in the left-right direction of the stop curtain 1. The energy absorbing structure 6 is preferably arranged below the adjacent mounting part 2, so that the whole piece of the check curtain can be conveniently buffered. The energy absorbing structure 6 is in a spring-like form and comprises a coherent curved surface with stretching and shrinking effects, and the cross section of the energy absorbing structure is in a sheet shape with a coherent broken line or a meandering curve. Preferably the thickness of the coherent curved surface of the energy absorbing structure 6 is 2 ± 1 mm.
Two ends of the energy absorption structure 6 are connected to the curtain through transition plates 7. The transition plate 7 is a plate-like structure perpendicular to the curtain body, preferably extending to the side of the wheel side. Two ends of the coherent curved surface of the energy absorption structure 6 are integrally connected with the transition plate 7, and an arc chamfer for increasing the connection area is formed at the connection position to be used as a transition reinforcing arc surface 8.
The longitudinal distance of the energy absorption structure 6 in the vertical direction in a free state before installation is 6-10% of the total longitudinal distance of the curtain in the vertical direction. After installation, the longitudinal distance change of the energy absorbing structure is very small and can be almost ignored.
The lower part of the retaining curtain 1 corresponding to the energy absorption structure 6 is of a flat plate structure, and the two sides of the flat plate structure are integrally processed with a protective edge 9 which is folded inwards and points to one side of the wheel, so that muddy water is prevented from splashing to the two sides.
The energy absorption structure is fixed below the mudguard through the mounting part, and when the energy absorption structure meets impact force of stones and obstacles on a road in the automobile form process, the impact force is buffered by utilizing the longitudinal extension and the front-back displacement of the energy absorption structure, so that the self and the mudguard are prevented from being damaged.
Example 2
The difference between this embodiment and embodiment 1 is that, as shown in fig. 6, the energy absorbing structure 6 has an irregular curved shape, and the effect of absorbing energy when being impacted can be achieved as well. The curves in the above and the embodiment 1 are only given as examples, and the curves meeting the buffering and energy absorbing functions can be adopted as long as the curves have the telescopic function in the actual production.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention by equally replacing or changing the technical idea of the present invention within the technical scope of the present invention.
