The maximum effective plasticstrain of peripheral parts compares the elongation after fracture of itself and material at this, to judge front tow hook
Whether laws and regulations requirement is met.And in actual condition, automobile will appear some special operation conditions: such as vehicle gets down hopeless in a quagmire, sand pit,
Under these special operation conditions pulling force suffered by front tow hook be greater than 0.5 times of car mass, at this moment frame front cross beam assembly connection bolt by
To the torque formed at towing hook, mounting plate is pulled because being generated overturning deformation by torque so as to cause towing hook.
Utility model content
To solve the above problems, the utility model provides a kind of automobile energy-absorbing cartridge, by energy-absorption box and installation
Stiffening plate is set between plate, to enhance the fastness between mounting plate and frame front cross beam.It prevents when automobile draws and drags operating condition, because
Mounting plate deforms and towing hook is caused to pull.
The technical solution of the utility model is as follows:
A kind of automobile energy-absorbing cartridge, including box body, one end of box body are fixedly connected with mounting plate, which is characterized in that institute
It states mounting plate and box connection is additionally provided with L-shaped stiffening plate；Stiffening plate includes the bottom plate being connected with mounting plate and and box
The side plate that body is connected；The connecting hole and location hole for installing vehicle energy absorption box are offered on the bottom plate.
Using the technical solution of the utility model, by the junction of mounting plate and box body be arranged L-shaped stiffening plate come
The fastness connected between enhancing box body and mounting plate, and stiffening plate can resist the torque from towing hook.It prevents from drawing in automobile
When dragging operating condition, due to mounting plate deformation caused by towing hook the case where pulling, and automobile is being realized by connecting hole and location hole
More accurate, long service life is assembled in the installation of energy-absorbing cartridge.
Preferably, the mounting plate edge is formed with the first flange；One lateral wall of the box body is resisted against described first
On the inner sidewall of flange corresponding position.Mounting plate is subjected to flange, the rigidity of enhancing mounting plate itself is not only able to, to enhance
The non-deformability of mounting plate；The fastness connected between mounting plate and box body can also be enhanced；And box body can be positioned,
Convenient for the assembly of box body and mounting plate.
Preferably, the second flange, the extending direction of the second flange and reinforcement are formed on the bottom edge of the stiffening plate
The side plate of plate is consistent；Stiffening plate also passes through the second flange outer wall and is resisted against on the inner sidewall of the first flange corresponding position.It can increase
While the non-deformability of strong stiffening plate itself, the fastness between stiffening plate and mounting plate is improved.
Preferably, the mounting plate is equipped with for mounting plate to be hung over to the pre- hook on crossbeam；Link up in advance to box body
Opposite direction extends.Automobile energy-absorbing cartridge is hung on crossbeam by linking up in advance, is easily installed, it is easy to operate.
Preferably, the stiffening plate is symmetrically distributed in the two sides of box body.Guarantee the fastness that mounting plate is connect with box body
Meanwhile it ensure that the balance of entire automobile energy-absorbing cartridge.
The beneficial effects of the utility model are to be connected firmly between components；The non-deformability of mounting plate and stiffening plate
By force, it prevents from causing towing hook to pull because of mounting plate deformation, assembly is accurate, long service life when automobile draws and drags operating condition.
Detailed description of the invention
Fig. 1 is the axis geodesic structure schematic diagram of the utility model.
Fig. 2 is the positive structure diagram of Fig. 1.
In figure, box body 1, mounting plate 2, the first flange 2.1, stiffening plate 3, connecting hole 3.1, location hole 3.2, the second flange
