Detailed description of the invention
In the present invention, for ease of describing, the travel direction definition of reference vehicle is hereinafter mentioned "front", "rear", "left", "right", and with reference to vehicle vertical direction define hereinafter mention " on ", D score.
(first embodiment)
As shown in Figure 4, it is used for being fixed to the squab panel 2 of vehicle according to the bumper holder 1 of the present invention. In this embodiment, the taillight of vehicle left side is arranged on this support 1, meanwhile, and a left side for bumper 3 End is also mounted to this support 1 and is supported by this support 1.
Fig. 5 to Fig. 7 shows the detailed construction of the support 1 according to the present invention.As it is shown in figure 5, Frame 1 includes the cylinder 12 that rack body 11 and the bottom forward side from rack body 11 extend, support Body 11 is for being installed to squab panel 2 by taillight, and the rear end of cylinder 12 is connected use with rack body 11 In supporting rear bumper 3 (see Fig. 6), cylinder 12 is formed with collapse type structure, to touch at vehicle Hit rear energy-absorbing.Being at a distance sufficiently large between this collapse type structure and rear end of cylinder 12 prevents impact energy Amount is transferred to car body.
As shown in Figure 6, cylinder 12 includes diapire 121, the sidewall 122 extended back from diapire 121 With at the bandy supporting walls in the rear end of sidewall 122 123.In this embodiment, cylinder 12 has Coniform shape.Diapire 121 is fixed to squab panel 2 by bolt and nut 4, and supporting walls 123 is used for connecing The inner surface of bumper 3 is to support rear bumper 3 after touch, thus improves the compressional stiffness of rear bumper 3. Collapse type structure is arranged on the sidewall 122 of cylinder 12.This collapse type structure be by sidewall 122 from Multiple steps 124 that body bending produces, as it is shown in figure 5, the plurality of step 124 is along sidewall 122 Circumference be spaced and exist betwixt and penetrate the space of described sidewall 122.
It addition, as shown in Figure 6, Figure 7, in the mounted state, the height of collapse type structure can be arranged At the above 5mm in final position of the position more than the final position of avoidance, preferably avoidance, thus anti- Only collision energy is delivered to squab panel 2.Additionally, collapse type structure (step 124) and support 1 Distance namely crumple length D between supporting walls 123 need long enough to prevent from colliding collapse type knot Part between the diapire 121 of structure and cylinder 12, thus prevent energy to be delivered to squab panel 2.Excellent Choosing, collapse type structure is positioned at the stop 5mm of avoidance, as shown in distance L in Fig. 7.
As it is shown in figure 5, collapse type structure includes two steps being positioned on the sidewall 121 of cylinder 12 124, but the quantity of step 124 and position are not limited to this.Situation according to different automobile types such as vehicle body Highly, squab panel height and the height of Obstacle avoidance model, the quantity of step 124 can be more or less than Two, and the position of step 124 can be along the circumference change of cylinder 12.As shown in Figure 8, Figure 9, In the case of avoidance is higher relative to bumper holder, step can be arranged on the top of cylinder 12, And the quantity of step can increase.
It is also contemplated that the form of collapse type structure can change.This collapse type structure not office Being limited to step, it can also is that the weakenings of other forms.Such as, along the circumference formation of sidewall 122 The multiple recesses being spaced, described recess is at least partially through the thickness of sidewall 122 thus is formed Weakenings.Described recess is connected to each other by connecting portion.In this embodiment, described recess passes sidewall The whole thickness of 122 thus form above-mentioned space, described connecting portion then forms above-mentioned step 124.Should Collapse type structure can be arranged on longitudinal direction (fore-and-aft direction) position of sidewall 122.But also It is contemplated that this collapse type structure can be arranged at multiple lengthwise positions of sidewall 122, from And form multistage crumple, absorb more energy further.
Although bumper holder is used for vehicle tail in this embodiment, but, those skilled in the art It is envisioned that vehicle head can also be applied to according to the bumper holder of the present invention.
It addition, be preferably integrated part by injection molding according to the bumper holder of the present invention.
(the second embodiment)
In the first embodiment, bumper holder is for installing one end of taillight and bumper.This enforcement Example is unlike first embodiment, and bumper holder is used only for installation insurance thick stick in its transverse ends Between part, namely the support in this embodiment is medium-height trestle.
Figure 10 shows this medium-height trestle 5, and medium-height trestle 5 has equally by longitudinally spaced at least one The collapse type structure that rank 51 are constituted, thus when preventing vehicle collision, transfer its energy to the middle part of squab panel.
Describe the bumper holder according to the present invention below and carry out the result of impact test.
When carrying out impact test, the taillight position of vehicle is collided, the collapse type of bumper holder First structure ruptures, and cylinder is followed avoidance and together deformed, thus absorbs energy.
In maintainability is tested, as shown in figure 12, avoidance becomes 10 ° of angles with vehicle body direction, and covers The area of body tail 40%, with the speed impacts of 16km/h.Find after experiment, according to the present invention Bumper holder intensity the most weak to such an extent as to absorb all of collision energy, squab panel is the most permanent Deformation, thereby may be ensured that replacing rear bumper correlated parts can complete maintenance.
In the pressing stiffness test of perceived quality, as shown in figure 13, at the bumper according to the present invention Support provides to bumper skin while enough supporting, the intrusion volume on the pressing big surface of bumper skin Less than 12mm, as shown in the hatched parts in Figure 13.
From the experiment above result understand, according to according to the bumper holder of the present invention in bar carrier While enhance the maintainability of vehicle rear, greatly reduce maintenance cost.
Although describing the present invention by reference to preferred embodiment, it is to be understood that the present invention does not limits to In preferred embodiment and structure.It is intended that cover various amendment and equivalent arrangements.Additionally, to the greatest extent Manage preferred various combination and structure, including other combinations of more, less or only a single element With structure the most within the spirit and scope of the present invention.
