Preferably, described installing hole boss is welded on the periphery of the installing hole on backplate of the described end.
Preferably, described buffer structure is rubber or foam.
This utility model embodiment also provides for a kind of automobile, and described automobile includes above-mentioned end guard board structure.
The beneficial effect of this utility model embodiment at least includes:
This programme is by arranging the peace of erection & lift hole strength on the end face with the end backplate of frame contact
Dress hole boss, arranges the buffer structure of the stand under load intensity reducing installing hole on installing hole boss, it is ensured that
Installing hole periphery on end backplate intact, and then ensure the connection of bolt.And this utility model simple in construction,
In fall end installing hole stand under load intensity, on the basis of improving the service life of end backplate, it is possible to decrease technological forming is difficult
Degree, it is to avoid occur fatigue damage occurring at the installing hole periphery solved on end backplate, causes spiral shell in prior art
The technology difficulty existed during the problem of bolt Joint failure is big, assembler duration and the high situation of cost.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
This utility model is described in detail by body embodiment.
An aspect according to this utility model embodiment, it is provided that a kind of end guard board structure, such as Fig. 1～figure
Shown in 6, including: the end backplate 2 being connected with vehicle frame 1, on the end face that end backplate 2 contacts with vehicle frame 1
Being provided with at least one installing hole reinforcement structure 3, installing hole reinforcement structure 3 includes: be arranged on end backplate 2
On the peripheral installing hole boss 4 of installing hole, and be arranged on installing hole boss 4 with installing hole boss
The buffer structure 5 of 4 couplings.
Concrete, by arranging installing hole reinforcement structure 3 on the end face that end backplate 2 contacts with vehicle frame 1,
Installing hole reinforcement structure 3 includes: the erection & lift hole strength that the installing hole being arranged on end backplate 2 is peripheral
Installing hole boss 4, and the stand under load intensity for reducing installing hole being arranged on installing hole boss 4 is slow
Rush structure 5, it is ensured that the installing hole periphery on end backplate 2 intact, and then ensure the connection of bolt.
Wherein, the quantity of installing hole reinforcement structure 3 can determine according to the quantity of installing hole on end backplate 2.
This utility model example structure is simple, can improve end backplate 2 in fall end installing hole stand under load intensity
Service life on the basis of, reduce technological forming difficulty, it is to avoid occur in prior art solve end backplate
The technology difficulty existed during the problem that fatigue damage occurs in the installing hole periphery on 2, cause bolt Joint failure
Greatly, assembler duration and the high situation of cost.
