Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
In the present invention it should be noted that term " on " "lower" " left side " " right side " "vertical" "horizontal" "inner" "outside" etc.
It is to be based on the orientation or positional relationship shown in the drawings, it is only for convenient for description the utility model and simplify description, without
It is that the device of indication or suggestion the utility model or element must have a particular orientation, therefore should not be understood as practical new to this
The limitation of type.
Embodiment
It please refers to shown in Fig. 1 and Fig. 2, the utility model discloses a kind of car protective devices, for realizing fuel tank or electricity
The protection of pond case.It includes outer framework 1, guard beam 2 and guard beam attachment device 3.
1 rectangular frame-shaped of outer framework, is made of square tube, and the wall thickness of the square tube is not less than 4mm.
Guard beam 2 is at least together, is arranged along the horizontal and is protected with the region the left and right grid beam between outer framework 1.Its
For the channel steel that both ends block, waist thickness is not less than 4mm.
The group number of guard beam attachment device 3 is consistent with the road number of guard beam 2, and each group guard beam attachment device 3 includes two attachment bases 31
And two tension spring 32.Two attachment bases 31 are respectively welded on the inside of the left and right grid beam of outer framework 1, and each tension spring 32 is respectively by the two of guard beam 2
Side connect (the present embodiment is to connect by bolt assembly, to be easily changed after the damage of tension spring 32) with two attachment bases 31, and two draw
The line footpath of spring 32 is 6-8mm, outer diameter 35-50mm, and circle number is less than 5 circles.
In this way, tension spring 32 is first had an effect when the side hatch door of car is hit, impact force is gradually reduced, when it is reached
When to limit travel, guard beam 2 starts to play a role.
As shown in figure 3, being to be broken after preventing tension spring 32 from reaching the limit of stroke, guard beam 2 is caused to fall off, car protective device is also
Including anti-drop device 4.The group number of anti-drop device 4 is consistent with the road number of guard beam 2.Each group anti-drop device 4 includes two first anticreep seats
41, two second anticreep seats 42 and two pull rods 43.Two first anticreep seats 41 are welded on the upside or downside at 2 both ends of guard beam, and two
The position that two anticreep seats 42 correspond respectively to two first anticreep seats 41 is welded on the inside of the left and right grid beam of outer framework 1.Two pull rods 43
The the first anticreep seat 41 and the second anticreep seat 42 of two sides are separately connected in a manner of the bolt of hole, two pull rods 43 are not less than for diameter
The bolt of 10mm, the head of the end of thread, which is screwed on, nut 44 (preferably double nut) and to be welded.
Herein, the stroke that pull rod 43 allows the first anticreep seat 41 to slide is in two kinds of situation: 1, reaching capacity stroke in tension spring
Before, pull rod 43 works, and the crumple stage is terminated, into the rigid protection stage；2, after tension spring is pulled off, pull rod 43 is just acted as
With into the rigid protection stage.Using which kind of mode, mainly follow whether its protected side there are enough crumple spaces.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
