Abstract
Motor decorative cover installation structure and pedestrian head guard method disclosed by the invention.Motor decorative cover installation structure includes: decorative cover of engine, bolt and rubber bushing.Engine decorative shroud rim installation point fixes glue bushing, the vertical fixed and arranged of bolt is in engine body upper end, rubber bushing section is in two bolt blocked holes being overlapped vertically, and two blocked holes can be extruded expansion by one to accommodate the channel connection that bolt bolt head passes through.When pedestrian head and enging cabin collide, pedestrian head occurs to contact for the first time and secondary contact occurs with decorative cover of engine with engine bonnet, impact force is transmitted to rubber bushing by decorative cover of engine, and stud bolt head enters the second bolt blocked hole through channel pressurization by the first bolt blocked hole.
Description
Technical field
The invention belongs to automotive crash safety fields, and in particular to motor decorative cover installation structure.
Background technique
With the increase of domestic automobile ownership, the security performance of automobile is just increasingly by the concern of the majority of consumers.
And the safety of automobile will not only consider the safety of passenger, it is also contemplated that the safety of goers outside vehicle.In engine nacelle
Vertical direction (Z-direction) space size is a key factor for determining pedestrian head injury.Currently in order to guaranteeing cabin space
Aesthetics and shielding, side configures a decorative cover of engine on the engine, but for compact car, head energy-absorbing space
Limited, the energy-absorbing space of the vertical space of enging cabin and part pedestrian head can be sacrificed later by being assembled with decorative cover of engine,
Limit the effect of protection pedestrian head.
Summary of the invention
The invention discloses motor decorative cover installation structures, solve compact car engine room inside head energy-absorbing space
Limited problem, while guaranteeing the aesthetics and shielding of cabin again.
The invention also discloses the pedestrian head guard methods using motor decorative cover installation structure, solve compact
The limited problem in car engine room inside head energy-absorbing space, while guaranteeing the aesthetics and shielding of cabin again.
The present invention discloses motor decorative cover installation structure, comprising: decorative cover of engine, bolt and rubber bushing；It is described
Engine decorative shroud rim installation point fixes rubber bushing erection support, and the rubber bushing screws in and is fixedly mounted on the rubber
In glue bushing erection support, the vertical fixed and arranged of bolt is in engine body upper end；The rubber bushing section is in vertical
The the first bolt blocked hole and the second bolt blocked hole of overlapping, two blocked holes can be extruded expansion by one to accommodate bolt
The channel connection that bolt head passes through；Two bolt blocked hole sizes and bolt bolt head size immovable fitting；When assembly, bolt bolt head card
It connects in the first bolt blocked hole.
Further, the bolt bolt head is in bulb-type, and the blocked hole section is in the ball with bolt bolt head immovable fitting
Face shape.
Using the pedestrian head guard method of above-mentioned motor decorative cover installation structure, pedestrian head and enging cabin occur
When collision, pedestrian head and engine bonnet occur contact for the first time and with decorative cover of engine generation is secondary contacts, impact force
It is transmitted on rubber bushing by decorative cover of engine, stud bolt head enters the second spiral shell through channel pressurization by the first bolt blocked hole
Bolt blocked hole.
Advantageous effects of the present invention are as follows: under conventional sense, ball stud is connected to the first bolt blocked hole, can satisfy
The installation requirement of decorative cover of engine.When danger occurs, pedestrian head and engine bonnet occur first time making contact and with
When secondary collision contact occurs for decorative cover of engine, impact force is transferred force on rubber bushing by decorative cover of engine, ball
Header stud enters the second bolt blocked hole, and the deformable squeeze in channel is the impact stroke for extending head, increases head energy-absorbing
Space.Better protective effect is played to pedestrian head.In addition, the configuration of the present invention is simple, can't serve as a contrast in traditional rubber
Increase cost on the basis of set；It is easily assembled, and the channel inside rubber bushing can be set according to different automobile types and extend stroke,
It is easy to spread.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of rubber bushing of the invention；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 arranges motor decorative cover installation structure assembly figure；
In figure, 1- rubber bushing, 2- the second bolt blocked hole, 3- the first bolt blocked hole, the channel 4-, 5- rubber bushing peace
Fill support, 6- decorative cover of engine, 7- bolt.
Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
As shown in Figure 1 to Figure 3, motor decorative cover installation structure, comprising: decorative cover of engine 6, bolt 8 and rubber lining
Set 1.
Engine decorative shroud rim installation point fixes rubber bushing erection support 5, and rubber bushing 1 is screwed in and is fixedly mounted on
In the rubber bushing erection support 5, the vertical fixed and arranged of bolt 8 is in engine body upper end.1 section of rubber bushing is in vertical
The the first bolt blocked hole 3 and the second bolt blocked hole 2 of overlapping, two blocked holes can be extruded expansion by one to accommodate spiral shell
The channel 4 that bolt bolt head passes through is connected to, two bolt blocked hole sizes and bolt bolt head size immovable fitting.
When assembly, bolt bolt head is connected in the first bolt blocked hole 3.Bolt bolt head can use bulb-type, blocked hole
Section is using the spheric with bolt bolt head immovable fitting.
Using the pedestrian head guard method of motor decorative cover installation structure, pedestrian head collides with enging cabin
When, pedestrian head and engine bonnet occur contact for the first time and with decorative cover of engine generation is secondary contacts, impact force passes through
Decorative cover of engine is transmitted on rubber bushing, and 7 bolt head of stud enters the second bolt through channel pressurization by the first bolt blocked hole 3
Blocked hole 2.
As impact force gradually increases, the stud 7 of bulb-type enters the second bolt blocked hole, extends the shock row on head
Journey increases head energy-absorbing space, reduces head injury value.
