Description
Technical field
The utility model is set and a kind of automotive interior part, and in particular to a kind of automobile door guard plate energy absorbent block.
Background technology
Energy absorbent block is all carried on most of driver's cab of sedan and the protective plate of vehicle door interior decoration assembly of the passenger side, it is normally at car door
The hip position of the right lower quadrant of backplate, i.e. occupant.Because hip is the weaker and important position of human body, its corresponding door shield
Position where plate is more prominent,, will be to multiplying if good energy-absorbing function can not be played when side collision occurs for vehicle
Member causes serious injury.With the continuous improvement required vehicle safety, the security requirement for interior design is also more next
It is higher.Usual door-plate hip position is all designed with energy absorbent block, and many energy absorbent blocks are foamed into using PU foamings or EPP at present
Type, its principle is mainly by producing elastic deformation after itself compression to absorb the energy that shock is produced, so as to protect occupant to pacify
Entirely.But often volume is larger for such energy absorbent block, and energy-absorbing effect is poor and manufacturing cost is higher.Further, since used
Material is PU (English polyurethane abbreviation, refer to polyurethane material) or EPP (English Expanded polypropylene
Abbreviation, refer to PP foam material) material, when being welded with door shield body, because and PP (English Polypropylene's
Abbreviation, refers to polypropylene) material compatibility is poor between the door shield body of resin material, easily welded in batch production
Loosely, the problem of solder joint loosens is caused, welding quality and stability are whard to control.
Collision energy is absorbed to overcome above mentioned problem to be deformed using raised crumple in currently available technology, but its design
Energy-absorbing block structure is complex, and because the limitation by structure can not absorb collision energy to greatest extent.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of use and door shield bulk material
The automobile door guard plate energy absorbent block of consistent PP resin material.
A kind of automobile door guard plate energy absorbent block, including energy-absorbing block body, described energy absorbent block body shape are class equilateral three
Angular, the position at three angles sets three cup-shapeds directed downwardly raised on the energy-absorbing block body of class equilateral triangle, three cup-shapeds
Projection is circle in isosceles triangle arrangement, the raised cross section of described cup-shaped, and the raised inside of cup-shaped is cavity structure, cavity knot
Energy absorbent block body wall opening, the weldering of the centrally disposed and car door guard plate welding in the raised lower end outside face of cup-shaped are run through in the upper end of structure
Connect post, lower end outside face and the plane that the plane where energy-absorbing block body is horizontal direction.
Further, the axis of symmetry at three angles of the energy-absorbing block body crosses the upper end section diameter of a circle of cup-shaped projection.
Further, the diameter of the raised cross section from the bottom to top of the cup-shaped is in the trend gradually increased.
Further, connected unit is provided with the raised lower surface of described cup-shaped, described welded post is arranged at connection
The center of table top, the connection table top is the plane of horizontal direction, and from top to bottom the diameter of cross section is in be gradually reduced to connected unit
Trend.
Further, described energy absorbent block is to use the direct integrated injection molding of PP resin raw materials.
The beneficial effects of the utility model：(1) it is in isosceles triangle by energy-absorbing block body class triangular design and cup-shaped projection
Symmetrical setting, energy absorbent block is fitted with car door metal plate more and consolidate, and 3 stress make to be more uniformly stressed, and increase vapour
The energy absorption of the raised crumple deformation of cup-shaped during Ce Touch occurs for car, reduces the energy for being delivered to automobile door protection panel, multiplies so as to protect
Objective safety；（2）Energy absorbent block uses the PP material consistent with automobile door protection panel material, makes welding firm, improves welding quality and guarantor
Demonstrate,prove quality stability；(3) structure design of energy absorbent block is simple, integrated injection molding can be used, when can either increase vehicle side impact
Energy-absorbing, meet again cost reduction demand.
Brief description of the drawings
Fig. 1 is a kind of front view of automobile door guard plate energy absorbent block involved by the utility model.
Fig. 2 is a kind of upward view of automobile door guard plate energy absorbent block involved by the utility model.
Respectively it is labeled as in figure：1 energy-absorbing block body, 2 cup-shapeds are raised, 3 connected units, 4 connection table tops, 5 welded posts.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated.
As depicted in figs. 1 and 2, a kind of automobile door guard plate energy absorbent block, including energy-absorbing block body 1, described energy absorbent block sheet
Body 1 is shaped as class equilateral triangle, and the position setting three at three angles is directed downwardly on the energy-absorbing block body 1 of class equilateral triangle
Cup-shaped projection 2, three cup-shaped projections 3 are in isosceles triangle arrangement, and the cross section of described cup-shaped projection 3 is circle, cup-shaped projection 3
Inside is cavity structure, and energy absorbent block body wall opening, the lower end outside face of cup-shaped projection 3 and energy-absorbing are run through in the upper end of cavity structure
Plane where block body 1 is the plane of horizontal direction.
The axis of symmetry at three angles of the energy-absorbing block body 1 crosses end section diameter of a circle in cup-shaped projection 2, so height
Symmetrical three-legged structure is set, and makes the connection of energy absorbent block and car door metal plate and car door guard plate even closer, and is more uniformly stressed,
Being capable of absorbing side impact energy to greatest extent.
The diameter of raised 2 cross sections of the cup-shaped is from the bottom to top in the trend gradually increased, and the structure of the cup-shaped projection 2 is set
Meter advantageously reduces the energy that goblet lower surface is delivered to after crumple deformation energy-absorbing.
Connected unit 3 is provided with the lower surface of described cup-shaped projection 2, the welded post 5 welded with car door guard plate is arranged at
Connect the center of table top 4, the connection table top 4 is the plane of horizontal direction, the diameter of the cross section of connected unit 3 be in from top to bottom by
Decrescence small trend, the setting of connected unit 3 is to be more beneficial for the tight fit of energy absorbent block and car door guard plate.
Described energy absorbent block is to use the direct integrated injection molding of PP resin raw materials.
When side collision occurs for vehicle, the impulsive force that collision is produced can be delivered on door shield by car door metal plate, by
It can be deformed gradually crumple of caving in three hollow cup-shaped projections of energy absorbent block, so that opposition is reduced, to reach
The purpose of apparatus with shock absorbing, greatly reduces the impact force being delivered on door shield, to protect passenger's safety.
In a word, the automobile door guard plate energy absorbent block of the utility model design, can either farthest absorb Che Liang Ce Touch
When collision energy, protect passenger safety, can increase again with automobile door protection panel weld fastness；It is simultaneously simple in construction, into
This is cheap.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
