Abstract
An automotive bumper comprises a bumper body and a locating frame. A buffering space is formed between the bumper body and the locating frame. Three to five connecting rods are arranged in the buffering space. The bumper body is fixedly mounted on the locating frame through the connecting rods. The automotive bumper is simple, compact and reasonable in structure, convenient and fast to assemble, reliable in connection and capable of reducing impact pressure from the outside effectively and better playing a role in buffering, the impact resistance of the automotive bumper is improved, the collision strength can be lowered to the minimum, the personal and property safety is guaranteed effectively, the reliability of automobile running is improved greatly, and the automotive bumper is easy to use and popularize.
Description
Technical field
The present invention relates to technical field of automobile parts, particularly relate to a kind of bumper。
Background technology
Bumper is the safety device absorbing and slowing down foreign impacts power, protection vehicle body front and rear part; existing bumper; it is generally the arc shell structure being made up of steel plate punched; collision process absorbs collision energy by the deformation of bumper; its shock absorbing effect, to protect the life security of occupant。But; owing to existing bumper depends merely on the deformation of housing to absorb consumption collision energy; therefore its buffering energy-absorbing function is good not enough; the protective capability of occupant and vehicle itself is need to improve by it, and existing bumper is monolithic construction, is easily damaged when colliding; the shock resistance of bumper is relatively low; being difficult to collision power to be down to minimum, the personal safety as well as the property safety of occupant is difficult to be protected, and greatly reduces the safety of running car。
Therefore, the problems referred to above are the problems should paid attention to and solve in automotive bumper design and use procedure。
Summary of the invention
For above-mentioned Problems existing, the present invention provides a kind of simple in construction, the bumper that security performance is higher。
The technical solution of the present invention is: a kind of bumper, including bumper body and locating rack, it is provided with cushion space between described bumper body and described locating rack, being provided with 3-5 connecting rod in described cushion space, described bumper body is fixedly mounted on described locating rack by described connecting rod。
Further improvement of the present invention is in that: being provided with spring between described connecting rod with adjacent connecting rod, described spring direction is consistent with connecting rod direction。
Further improvement of the present invention is in that: described connecting rod is externally provided with sleeve pipe, is provided with implant between described sleeve pipe and described connecting rod, and described implant is polyurethane foam。
Further improvement of the present invention is in that: described locating rack is steel structure。
Further improvement of the present invention is in that: the inwall of described bumper body is provided with reinforcement。
Further improvement of the present invention is in that: the external side of described bumper is provided with a horizontal stripe shape buffer plug, and in described buffer plug, arrangement is provided with cushion, and described cushion is silica gel。
During collision scenario, the buffer plug stress of the external side of bumper, and cushioned by its internal implant, final stress is on locating rack, when impact force is lighter, bumper body is cushioned by buffer plug, owing to being filled with silica gel in described buffer plug, after impact force disappears, bumper body can return to original state, thus bumper being played certain protective effect, when impact force is heavier, when buffer plug is impaired, cushioned by the spring in cushion space and connecting rod, it is ultimately transferred to locating rack, so car body is played a protective role。
The invention has the beneficial effects as follows: this bumper is simple, compact and reasonable, easy to assembly fast, connect reliable, can effectively reduce from extraneous surge, play cushioning effect better, improve the shock resistance of bumper, collision power can be down to minimum, it is effectively guaranteed personal safety as well as the property safety, improves greatly the reliability of running car, it is easy to use and promote。

Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention being described in further detail, this embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and limits。
The technical solution of the present embodiment is: a kind of bumper, including bumper body 1 and locating rack 2, described locating rack 2 is steel structure, it is provided with cushion space 3 between described bumper body 1 and described locating rack 2, 4 connecting rods 4 it are provided with in described cushion space, described bumper body 1 is fixedly mounted on described locating rack 2 by described connecting rod 4, it is provided with spring 5 between described connecting rod 4 and adjacent connecting rod, described spring 5 direction is consistent with connecting rod 4 direction, described connecting rod 4 is externally provided with sleeve pipe 6, it is provided with implant 7 between described sleeve pipe 6 and described connecting rod 4, described implant 7 is polyurethane foam, the inwall of described bumper body 1 is provided with reinforcement 8, a horizontal stripe shape buffer plug 9 it is provided with outside described bumper body 1, in described buffer plug 9, arrangement is provided with cushion 10, described cushion 10 is silica gel。
During collision scenario, buffer plug 9 stress outside bumper body 1, and cushioned by its internal silica gel 10, final stress is on locating rack 2, when impact force is lighter, bumper body 1 is cushioned by buffer plug 9, owing to being filled with silica gel in described buffer plug 9, after impact force disappears, bumper body 1 can return to original state, thus bumper being played certain protective effect, when impact force is heavier, when buffer plug 9 is impaired, cushioned by the spring 5 in cushion space and connecting rod 4, it is ultimately transferred to locating rack 2, thus car body is played a protective role。
The present embodiment provides the benefit that: this bumper is simple, compact and reasonable, easy to assembly fast, connect reliable, can effectively reduce from extraneous surge, play cushioning effect better, improve the shock resistance of bumper, collision power can be down to minimum, it is effectively guaranteed personal safety as well as the property safety, improves greatly the reliability of running car, it is easy to use and promote。
Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
