Description
Technical field
The utility model relates to a kind of safety guard for automobile, particularly a kind of automobile buffer beam.
Background technology
Automobile buffer beam is car body main composition parts, the life security of reasonable Usefulness Pair passengers inside the car of its design and the damage rate of vehicle main frame, maintenance cost have direct relation, but at present, a lot of vehicle is had to subtract the design of joining and even directly eliminating collision prevention girders, great potential safety hazard is present in for customer, and collision prevention girders is in collision process, effectively can reduce the damage of the body vitals of waiting for bus to driving engine, reduce the maintenance cost of car owner.
What collision prevention girders two ends connected is the low speed energy-absorption box that yield strength is very low, is then connected on car body longeron by the form of bolt.Low speed energy-absorption box effectively can absorb collision energy when vehicle generation low speed collision, reduces impact as far as possible to the infringement of chassis runner, can reduce maintenance cost like this, and bolted mode can be changed to collision prevention girders more easily.
In high speed offset collision, impact on the left of vehicle body (or right side) can be delivered to right side (or left side) by actv. by collision prevention girders, allows whole car body go to absorb collision energy as far as possible.When low speed collision occurs (being generally below 15km/h), collision prevention girders can avoid impact to the infringement of longeron before and after vehicle body, reduces maintenance cost.
In finding out that daily city is current thus, particularly happen occasionally at the low speed collision of city proper, collide with unavoidable, be extremely necessary so automobile buffer beam is easily changed in design and installation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the automobile buffer beam that a kind of novel structure, cost are reasonable, easy for installation is provided.
Scheme of the present utility model is as follows:
A kind of automobile buffer beam, comprise crossbeam, be arranged at the fixed mount at crossbeam two ends, crossbeam is arc, and middle part is outwardly, and fixed mount mates with car body front cross rail energy-absorbing post, and fixed mount is provided with the bolt hole fixing with the energy absorption device of former car body longeron front end.
Described bolt hole at least comprises 1 to being fixed on energy-absorbing post, then cross rail outer is separately established 1 right, makes crossbeam and energy-absorbing post be that face contacts.
Described section of beam is " several " font of half-twist.
Described crossbeam left upper portion is reserved with dodges car body parts installation gap.
Described installation gap and crossbeam otch are arc transition.
Be provided with energy-absorbing foam block outside described fixed mount, energy-absorbing foam block to be arranged on outside fixed mount in groove.
The beneficial effects of the utility model:
1. novel in design, cost is reasonable, is convenient to car owner and loads installation;
2. collision prevention girders fixed mount contacts with energy-absorbing cylinder, both increases firmness, makes again energy-absorbing post play one's part to the full;
3. mate with outer insurance shell, easily inside is installed, do not affect the appearance and parts in car.
Accompanying drawing explanation
Fig. 1 is the utility model automobile buffer beam perspective view.
Fig. 2 is the utility model automobile buffer beam structure schematic diagram.
Fig. 3 is the utility model automobile collision preventing sill bolt energy-absorbing foam block structure schematic diagram.
Fig. 4 is the utility model automobile buffer beam construction profile schematic diagram.
Wherein, marking 1 in figure is crossbeam, and 2 is fixed mount, and 3 is bolt hole, and 4 is bolt hole outside energy-absorbing post, and 5 is groove outside fixed mount, and 6 is energy-absorbing foam block, and 7 for dodging car body parts installation gap, and 8 is otch.
Detailed description of the invention
embodiment one: see Fig. 1 to 3, a kind of automobile buffer beam, comprises crossbeam, be arranged at the fixed mount 2 at crossbeam 1 two ends, crossbeam 1 is arc, and middle part is outwardly, fixed mount 2 mates with car body front cross rail energy-absorbing post, and fixed mount 2 is provided with the bolt hole 3 fixing with the energy absorption device of former car body longeron front end.
Described bolt hole at least comprises 1 to being fixed on energy-absorbing post, then cross rail outer is separately established 1 right, makes crossbeam and energy-absorbing post be that face contacts.
Described crossbeam 1 left upper portion is reserved with dodges car body parts installation gap 7.
Described installation gap 7 is arc transition with crossbeam otch 8.
Be provided with energy-absorbing foam block outside described fixed mount 2, energy-absorbing foam block 6 to be arranged on outside fixed mount in groove 5.
embodiment two: slightly, substantially the same with embodiment one, different places is accompanying drawing: do not establish energy-absorbing foam block outside described fixed mount.
embodiment three: slightly, substantially the same with embodiment one, different places is accompanying drawing: described crossbeam 1 left upper portion does not need to establish dodges car body parts installation gap 7.
embodiment four: see Fig. 4, substantially the same with embodiment one, different places is: described crossbeam 1 cross section is " several " font of half-twist.
