Fig. 8 is the schematic sectional view that connects the support brace panel among Fig. 7.
The specific embodiment
As shown in Figure 1, the preceding protective device of conventional truck is made up of bumper/spoiler 4.Bumper/spoiler 4 is installed on the vehicle frame front portion, and and ground between have bigger distance (for example in truck).Thereby when the positive collision of another vehicle lower (for example car), take place easily to bore to hit, cause serious consequence with bumper height.
As shown in Figure 2, protection crossbeam 1 and two connection supports 2 (promptly a left side connects support and the right support that is connected) before comprising according to the vehicle front underrun protection device of the utility model one embodiment, and described connection support 2 be used for will the described preceding vehicle frame that crossbeam 1 is connected to vehicle that protects.As will be understood by the skilled person in the art, preceding protection crossbeam 1 be connected support 2 and can be various suitable shapes; Connect support 2 and the mode that protection crossbeam 1 before described is connected to carriage frame also can be had various ways, for example, be threaded (screw or bolted connection), perhaps welding or the like.This kind front underrun protection device has characteristic of simple structure, and on being mounted to vehicle the time, can prevent effectively or reduces at least and bore the generation of hitting.It is pointed out that this front underrun protection device to use and form the whole anterior protective device of vehicle with the bumper/spoiler of routine.
Still as shown in Figure 2, further comprise two connection support brace panels 3 (left side connects support brace panel and the right support brace panel that is connected) according to the front underrun protection device of another embodiment of the utility model, each connects support brace panel 3 at both ends places and precedingly protects crossbeam and the corresponding support that is connected is connected and forms a triangular structure with described respectively.Thereby the structure to front underrun protection device is strengthened.
(not shown) in a preferred embodiment, described connection support are used for being connected to by thread connecting mode (bolted connection or screw connect) vehicle frame of vehicle.Promptly on each connects support, have hole (through hole and/or tapped bore, the number in hole can for example can be provided with three holes according to settings such as requirement of strength), be used for bolted connection by passing described hole to the vehicle frame of vehicle.Thereby, after bumping, can change front underrun protection device apace.
In a preferred embodiment, described connection support is used to be connected to the longeron of vehicle frame.Thereby the impact force of head-on crash is directly passed to longeron, makes that cross member of frame need not to bear positive impact force, this helps reducing the requirement of strength to crossbeam.Further, described connection support can be used for being connected to by thread connecting mode the longeron of vehicle frame.Thereby, after bumping, can change front underrun protection device apace.
In a preferred embodiment, the cross-sectional plane of described preceding protection crossbeam is a rectangular tube.In other words, the periphery of the cross-sectional plane of preceding protection crossbeam is a rectangle, and interior week also is a rectangle.Like this, can realize higher intensity with less material.In addition, understanding as those of ordinary skills is that the size and the wall thickness in described rectangular tube cross section can be according to designs such as requirement of strength.
Referring to Fig. 5 and Fig. 6, in one embodiment, the cross-sectional plane of described connection support 2 is a flute profile, comprise and be used for the preceding protection crossbeam bonded assembly first limit 2a, be used for the vehicle frame bonded assembly second limit 2c with vehicle, and the connection side 2b that between first and second limits, extends, and described connection side under installing condition perpendicular to ground.Thereby protection crossbeam and vehicle frame is connected before realizing with plain mode.
Referring to Fig. 7 and Fig. 8, in one embodiment, it is triangle with the right cross-sectional plane that is connected the support brace panel that a described left side connects the support brace panel.Thereby a described left side is connected the support brace panel with the right side higher intensity can be arranged.
Referring to Fig. 4, according to an embodiment of the present utility model, provide a kind of vehicle, this vehicle comprises bumper/spoiler 4 and foregoing vehicle front underrun protection device 10, wherein said vehicle front underrun protection device is installed in the below or the oblique below of described bumper/spoiler.On traditional insurance thick stick device basic, protective device down before increasing, car pierces the truck front portion, the minimizing accident rate when can actv. preventing that car and truck from bumping.
More particularly, described vehicle is truck or commercial vehicle/comm..vehicle.Because the chassis of truck and commercial car is higher usually, the height of bumper/spoiler is higher, thereby the effect of described front underrun protection device will be bigger.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all drop within the protection domain of the appended claim of the utility model.
