Abstract
It the utility model is related to a kind of collision prevention girders of car.The device includes the impact beam being connected with bus frame crossbeam, and the impact beam is connected through some energy absorption devices with frame cross.Due to the presence of energy absorption device, which preferably absorbs the kinetic energy that collision produces, so that the harm that reducing collisions produces.
Description
Technical field
It the utility model is related to automobile frame technical field, more particularly to a kind of collision prevention girders of car.
Background technology
At present, national legislation claims collision prevention girders in car collision field, and car is usually not provided with anticollision in native land
Girder construction.But due to lacking collision prevention girders, when car runs into head-on crash, it is difficult to ensure that occupant, especially driver
And the safety of front-seat passenger.
The patent of entitled car anticollision girder construction, the application number of the patent are disclosed in existing Chinese patent database
For：201220691493.4, applying date 2012.12.14, Authorization Notice No. CN203020240U, authorized announcement date are
2013.06.26 its structure includes：One collision prevention girders, the collision prevention girders are horizontal by the vehicle frame of at least one energy-absorbing longeron and car
Beam connects.It is disadvantageous in that：The apparatus structure is simpler, and energy-absorbing effect is not good enough, therefore the anti-collision effect played is undesirable,
The life security of driver and passenger are difficult to ensure that.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, more reasonable, the anticollision effect that provides a kind of structure
The more outstanding car collision prevention girders of fruit.
In order to realize the purpose of above-mentioned utility model, technical solution adopted in the utility model：
A kind of collision prevention girders of car, including the impact beam being connected with bus frame crossbeam, the impact beam is through some suctions
Energy device is connected with frame cross.
During utility model works, impact beam is contacted with being hit thing, and impact beam deformation absorbs the kinetic energy that local collision produces,
Kinetic energy is passed to energy absorption device by impact beam at the same time, and energy absorption device deformation absorbs the kinetic energy that local collision produces.
Kinetic energy caused by collision is preferably absorbed for the ease of impact beam, the impact beam includes being connected with frame cross
Interior channel steel and for the outer channel steel with being hit thing and contacting, buffered part connection between the outer channel steel and interior channel steel.2
In order to ensure the rigidity of interior channel steel and outer channel steel, while stop the collision of oblique side, the interior channel steel and water jacket
The integral machine-shaping of steel forms, and the interior channel steel and outer channel steel include the flat segments parallel with frame cross and positioned at flat
The segmental arc of straight section both sides, the free end of each segmental arc are drawn close to frame cross.3
The kinetic energy that collision produces preferably is absorbed for the ease of the collision prevention girders, the energy absorption device includes one end and vehicle frame
Crossbeam connects, the telescopic rod that the other end is connected with impact beam, and compression spring is socketed with the telescopic rod.4
For the ease of the collision prevention girders preferably absorb collision produce kinetic energy, between the impact beam and frame cross between
Elastic rubber is filled with gap.5
Compared with prior art, the beneficial effects of the utility model are：Since the presence of energy absorption device, the collision prevention girders are more preferable
Ground absorbs the kinetic energy that collision produces, so that the harm that reducing collisions produces.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein, 1 frame cross, 2 impact beams, channel steel in 201,202 outer channel steels, 203 bolsters, 204 flat segments, 205 arcs
Shape section, 3 energy absorption devices, 301 telescopic rods, 302 compression springs, 4 elastic rubbers.
Embodiment
With reference to specific embodiment, the utility model is further described：
As described in Figure 1, a kind of collision prevention girders of car, including the impact beam 2 being connected with bus frame crossbeam 1, impact beam 2 wrap
Include the interior channel steel 201 that is connected with frame cross 1 and for the outer channel steel 202 with being hit thing and contact, outer channel steel 202 and interior channel steel
Buffered part 203 connects between 201, and the integral machine-shaping of interior channel steel 201 and outer channel steel 202 forms, interior channel steel 201 and water jacket
Steel 202 includes the flat segments 204 and segmental arc 205 positioned at flat segments 204 both sides parallel with frame cross 1, each arc
The free end of section 205 is drawn close to frame cross 1, and interior channel steel 201 is connected through some energy absorption devices 3 with frame cross 1, energy absorption device
3 are connected including one end with frame cross 1, the telescopic rod 301 that the other end is connected with impact beam 2, and compression is socketed with telescopic rod 301
Spring 302, is filled with elastic rubber 4 in the gap between impact beam 2 and frame cross 1.
During work, outer channel steel 202 is contacted with being hit thing, and kinetic energy is passed to buffering while outer 202 energy-absorbing deformation of channel steel
Part 203, passes to interior channel steel 201 while 203 energy-absorbing deformation of bolster by kinetic energy, and interior channel steel 201 is by the kinetic energy transmission of deformation
To energy absorption device 3, the 302 compression energy-absorbing of compression spring in energy absorption device 3, simultaneous retractable bar 301 is shunk, and elastic rubber 4 absorbs
The energy of collision.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can be special to some of which technology
Sign makes some and replaces and deform, these are replaced and deformation is within the protection scope of the present utility model.
