Degree is greater than the length of front beam 11.In this way, compare rectangular frame when, in front beam 11 and rear cross beam 12 apart from certain condition
Under, the length of left stringer 13 and right vertical beam 14 can draw collision energy and Dissipative Collisions power with longer conducive to bending deformation.
As shown in Figure 1, for the ease of first support 15, second support 16, third bracket 17 and the 4th bracket 18 and vehicle body
Connection, and by branch's impact force dispersion be transmitted on vehicle body, specifically, first support 15 is connected with the first installing arm 161,
First installing arm 161 is equipped with the first mounting hole 171 for connecting with vehicle body；Second support 16 is connected with the second installing arm
162, the second installing arm 162 is equipped with the second mounting hole 172 for connecting with vehicle body；Third bracket 17 is connected with third installation
Arm 163, third installing arm 163 are equipped with the third mounting hole 173 for connecting with vehicle body；4th bracket 18 is connected with the 4th peace
Arm 164 is filled, the 4th installing arm 164 is equipped with the 4th mounting hole 174 for connecting with vehicle body.More specifically, the first installation
Hole 171, the second mounting hole 172, third mounting hole 173 and the 4th mounting hole 174 pass through bolt and vehicle body with rubber respectively
Installation connection.
When impact force is little, and entire automobile front subframe 10 only has collision prevention girders 19 to damage, for the ease of replacing and reducing
Cost, specifically, 19 both ends of collision prevention girders are detachably connected with first support 15 and second support 16 respectively.In this way, can be by tearing open
Unload the collision prevention girders 19 that replacement has damaged deformation.
Bending deformation, which is carried out, for the ease of left stringer 13 and right vertical beam 14 draws collision energy, specifically, left stringer 13
Surface and the surface of right vertical beam 14 are equipped with reduction hole 20.
As shown in Figure 1, refinement ground, reduction hole 20 can be set as multiple, and multiple reduction holes 20 can be along left stringer 13 and right vertical beam
14 peripheral surface interval setting, can also be arranged along the longitudinal surface interval of left stringer 13 and right vertical beam 14；With left stringer 13
Linear deformation is gradually increased on direction from front to back with right vertical beam 14, weakens the quantity in hole 20 in direction from front to back
On gradually decrease, alternatively, it is adjacent two reduction hole 20 between the direction being spaced in from front to back on become larger.
As shown in Figure 1 to Figure 3, in order to enhance the stiffness and strength of left stringer 13 and right vertical beam 14, specifically, left stringer 13
It is equipped with inner cavity with right vertical beam 14, the next door 131 for inner cavity to be separated at least two individual cavities is equipped in inner cavity.This
The inner cavity of sample, left stringer 13 and right vertical beam 14 uses the structure type of multiple individual cavities, enhances left stringer 13 and right vertical beam
14 stiffness and strength.Inner cavity can be separated into cross sectional shape in " day ", " mesh ", " field " or " net " shape by refinement ground, next door 131
Etc. structure types, still, the multi-cavity structure form of inner cavity is not limited in above-mentioned several, can be adopted according to particular condition in use
With different multi-cavity structures.
A part of impact force is passed into first support 15 and second support 16 for the ease of collision prevention girders 19, specifically, is prevented
The both ends for hitting beam 19 are formed with the stabilizer blade 191 connecting respectively with first support 15 and second support 16.Wherein, stabilizer blade 191 is distinguished
It is detachably installed and is connect by bolt with first support 15 and second support 16.
As shown in Figure 1, refinement ground, stabilizer blade 191 includes at least two section support portions 1911, between two adjacent sections support portion 1911
It is separated by convex edge 1912.In this way, when impact force is transmitted on stabilizer blade 191, on direction from front to back, support portion 1911
To be badly deformed be also to carry out section by section, i.e. dissipation of the impact force on the stabilizer blade 191 is also to dissipate layer by layer section by section.
Further, for the ease of support portion 1911 is badly deformed and draws collision energy and Dissipative Collisions power, branch
The peripheral surface of support part 1911 is equipped with reduction hole 20.Refinement ground, reduction hole 20 can be set as multiple, and multiple reduction holes 20 can be along branch
The peripheral surface interval of support part 1911 is arranged, and can also be arranged along the longitudinal surface interval of support portion 1911；With support portion 1911
Linear deformation is gradually increased on direction from front to back, and the quantity in reduction hole 20 gradually subtracts on direction from front to back
Lack, alternatively, being become larger on the direction being spaced in from front to back between adjacent two reduction hole 20.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
