Abstract
The utility model discloses a formula car collision energy absorbing device, which is fixedly installed in front of a base plate on the head of a car and positioned inside an outer casing of a car body. The collision energy absorbing device is made of metal materials with a plurality of hollow holes on the cross sections, and honeycombed aluminum is the best material. The collision energy absorbing device can absorb a large amount of collision energy when being collided to deform, has fine energy absorbing effect, is much lighter compared with solid rubber with the same size, and can reduce integral weight of the car.
Description
Technical field
The utility model relates to a kind of racing car, refers to a kind of formula car collision energy-absorbing device especially.
Background technology
FSAE match is founded in 1979 by U.S.'s vehicle society of engineers, the university student of match request race-entry with one-year age, be no more than under 25000 dollars the funds, develop a free air capacity and is the 610C.C. racing car of lying fallow following holiday, assembling must be simply.This match emphasis is not than soon, and is intended to make safety and maneuverable contest type vehicle.Along with the flourish and various countries of auto-industry strengthen the auto-industry talent's cultivation, more and more countries, increasing school begins to participate in the FSAE contest.
The racing car design is that the elite of technical works such as automobile design, making, equipment, debugging embodies, and designing and producing of present domestic racing car is all fewer, has now and can utilize parts still less, and many parts all lean on the designer to design voluntarily.And university student's formula car designs and produces, and control is arranged on cost, and discharge capacity also must be controlled at below certain requirement, therefore reduce the overall weight of racing car, and the production convenience of racing car just seems particularly important.
The collision energy-absorbing device of formula car generally all adopts the rubber of monoblock, and in order to reach the energy-absorbing effect of expection, the size of rubber block is generally all about 10 centimeter square.Though rubber has energy-absorbing effect preferably, weight is but very heavy, will increase the overall weight of racing car, influences the rapid of racing car.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can effectively absorb energy and the lightweight formula car collision energy-absorbing device that produces when colliding.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of formula car collision energy-absorbing device, it is fixed on substrate the place ahead of racing car head, and is positioned within the body shell; This collision energy-absorbing device is made of the shape that the cross section has some hollow holes.
Described hollow hole is cellular.
Described collision energy-absorbing device is made of some aluminium plates that are bent into a plurality of stepped tooths, and each adjacent aluminum plates material is bonding mutually and constitute cellular aluminium section bar with the base of its stepped tooth.
After adopting such scheme, because collision energy-absorbing device described in the utility model adopts the section bar with some hollow holes to constitute, and with cellular aluminium section bar is the best, when this device is out of shape being collided, can absorb a large amount of collision energies, energy-absorbing effect is good, and the solid quite again rubber of relative size, in light weight a lot, can alleviate the overall weight of racing car.Moreover this device is when making, can earlier a monoblock aluminium sheet be bent into the sheet material with some stepped tooths, again the base of some above-mentioned sheet materials with its stepped tooth bonded together mutually, can constitute cellular aluminium section bar, its making is simple and convenient, is fit to university student's formula car single piece production and the low requirement of cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the utility model manufacturing process scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model was related is a kind of formula car collision energy-absorbing device, as shown in Figure 1 to Figure 3, described collision energy-absorbing device 1 is made of the shape that the cross section has some hollow holes 11, this hollow hole 11 is best with cellular, and generally adopting aluminium section bar or steel, is best with the aluminium.This collision energy-absorbing device 1 vertically is fixed on substrate 2 the place aheads of racing car head with hollow hole, and is positioned within the body shell 3.
Experiment shows, when the section bar with hollow hole is out of shape being collided, can absorbs a large amount of collision energies, thereby alleviate collision strength racing car, and cellular hole energy-absorbing effect the best.And, have the collision energy-absorbing device 1 of hollow hole 11, the rubber that relative size is suitable and solid, very light in weight adopts the more aluminium of lightweight, more can alleviate the overall weight of racing car.
In addition, the collision energy-absorbing device 1 that the aluminium section bar with hollow hole 11 that the utility model adopted is made can adopt the mode of one stretching section bar to make, but this production method cost is higher, is not suitable for the requirement of university student's formula car single piece production.For this reason, the utility model can be made cellular aluminium section bar in the following way: as shown in Figure 4, one monoblock aluminium sheet is bent into the sheet material 12 with some stepped tooths, the base of some above-mentioned sheet materials 12 with its stepped tooth bonded together mutually, so promptly constituted cellular aluminium section bar.
Claims (3)
1. formula car collision energy-absorbing device, it is fixed on substrate the place ahead of racing car head, and is positioned within the body shell; It is characterized in that: described collision energy-absorbing device is made of the shape that the cross section has some hollow holes.
2. formula car collision energy-absorbing device as claimed in claim 1 is characterized in that: described hollow hole is cellular.
3. formula car collision energy-absorbing device as claimed in claim 1, it is characterized in that: described collision energy-absorbing device is made of some aluminium plates that are bent into a plurality of stepped tooths, and each adjacent aluminum plates material is bonding mutually and constitute cellular aluminium section bar with the base of its stepped tooth.
