Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can be mutually combined.
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Embodiment one
The present embodiment relates to ceiling endergonic structure in a kind of car; in this car, ceiling endergonic structure is equipped with between ceiling panel beating and ceiling trim panel; in its overall structure; mainly include substrate, ribs and crumple portion; wherein, the structure of the main design idea of ceiling endergonic structure in the car that the present invention relates to, mainly crumple portion and crumple portion and ribs matching relationship therebetween; to realize absorption more preferable to impact force, transmission effect, improve the protective effect to occupant.
Describe and design philosophy based on overall structure as above, in the car that the present embodiment relates in ceiling endergonic structure, substrate 1 constitutes the installation foundation of other structure members, its generally one platy structure, its thickness is 3mm, being binding face in the bottom of the substrate 1 of state shown in Fig. 1, this binding face has and the accompanying structure of ceiling trim panel as described below, to realize the laminating of substrate 1 and ceiling trim panel；Upper surface in the substrate 1 of state shown in Fig. 1 is installed surface 101, for forming the installation to miscellaneous part.Being used for, with the left side of the substrate 1 of state shown in Fig. 1, the ribs 2 that is connected, right-hand part is used for the crumple portion 3 that is connected；Ribs 2 and crumple portion 3 are installed by the laminating of substrate 1 with ceiling trim panel, and be disposed on length of wagon direction, and crumple portion 3 relative to ribs 2 closer to the front end of vehicle body, i.e. crumple portion 3 is arranged near the front end of vehicle body, and ribs 2 is slightly away from the front end of vehicle body.
The setting of ribs 2, mainly while improving the intensity of whole device and ceiling trim panel, it is ensured that the dispersion effect of impact force and improve the energy-absorbing effect in crumple portion 3.In the present embodiment, ribs 2 is made up of multiple parallel ribs 201, and multiple parallel ribs 201 are arranged on installed surface 101 in length of wagon direction spacing, and becomes class to be arranged in parallel between each parallel rib 201.In order to preferably play the performance effect of ribs 2, parallel rib 201 is 8-15mm along the width in length of wagon direction, width such as rib 201 parallel in the present embodiment is 10mm, and the spacing between adjacent two parallel ribs 201 is 9-11mm, if the spacing in the present embodiment is 10mm.In addition, in order to make ribs 2 can preferably coordinate vehicle ceiling panel beating, preferably play the action effect of ribs 2, parallel rib 201 is along the top of vehicle-body width direction, it is configured to and the accompanying shaped form of ceiling panel beating as described below, so, when parallel rib 201 receives external force and towards the motion of ceiling panel beating and contacts with ceiling panel beating, increase parallel rib 201 and the contact area of ceiling panel beating, make impact force obtain more excellent weak effect.
In addition, as shown in Figure 1, in order to improve the action effect of ribs 2 further, in the present embodiment, ribs 2 is divided into district 203 of Duan Lei district 202 and Chang Lei, specifically, parallel rib 201 in Duan Lei district 202, the length extended in the vehicle width direction is the length of parallel rib in being less than Chang Lei district 203, in Qie Duanlei district 202, the quantity of parallel rib is more than the quantity of parallel rib in Chang Lei district 203, this setting makes substrate 1 on structure shows, the width of the left side of substrate 1 is slightly less than the middle part width of substrate 1, so, ribs 2 entirety is made to form echelon allocation when transmitting impact force, preferably improve the performance of whole product.
Crumple portion 3 is adjacent to ribs 2 on installed surface and arranges, in the present embodiment, crumple portion 3 is adjacent to Chang Lei district 203 and arranges, the effect in crumple portion 3 is to be by External Force Acting, being capable of crumple, in the present embodiment, crumple portion 3 is two arranged along length of wagon direction, and the global shape in each crumple portion 3 be arranged on dash forward in the egg torr shape of installed surface 101, the wall thickness in the crumple portion 3 of each egg torr shape is 3mm.
In addition, in order to set up ribs 2, crumple portion 3 and the relation of existing vehicle part, improve power transmission, discomposing effect further, in the present embodiment, being integrated with on substrate 1 by projecting the handrail receiving portion 4 put on installed surface 101, handrail receiving portion 4 is disposed adjacent along vehicle-body width direction with crumple portion 3, simultaneously, in order to make crumple portion play more preferable crumple energy absorption performance, the upper prominent height in crumple portion 3 is more than the upper prominent height of handrail receiving portion 4.
In order to realize being located by connecting between substrate 1 and ceiling trim panel, in the present embodiment, at the corner point of substrate 1, it is equipped with connecting portion 5, as in the present embodiment, connecting portion 5 uses bonding post, simultaneously, in order to make connecting portion 5 can and ceiling trim panel between be preferably located by connecting, the periphery of substrate 1 is provided with flange 6, and flange 6 is when mounted, can be with inclusion on ceiling trim panel, to improve the bonding strength between substrate 1 and ceiling trim panel and connective stability.
Embodiment two
The present embodiment relates to a kind of vehicle ceiling, as in figure 2 it is shown, in the vehicle roof structure of the present embodiment, including ceiling panel beating 7, ceiling trim panel 8, between ceiling panel beating 7 and ceiling trim panel 8, it is formed with receiving cavity 9, within accommodating cavity 9, is provided with ceiling endergonic structure in the car of embodiment one.Fig. 3 shows ceiling trim panel 8 and the attachment structure sketch of ceiling endergonic structure in car, can know in conjunction with Fig. 2, ribs 2, the upper prominent direction in crumple portion 3 are towards ceiling panel beating 7, and the spacing between ceiling panel beating 7 and ceiling trim panel 8, i.e. accommodate the cavity 9 height space along vehicle body vertical direction, for ribs 2, the collecting in crumple portion 3.In the present embodiment, in order to preferably play the effect of ceiling endergonic structure in car, the height in parallel rib 201 and crumple portion 3 is and accommodates the 83% of cavity 9 height.
When vehicle generation side impact or rollover, impact force is carried in occupant's head, in order to realize the protection to occupant's head, occupant's head contacts with ceiling trim panel 8, its active force to ceiling trim panel 8, pass to ribs 2 and crumple portion 3, ribs 2 and crumple portion 3 move to ceiling panel beating 7, when ribs 2 all contacts with ceiling panel beating 7 with crumple portion 3, the power transfer route in crumple portion 3 is as shown in Figure 4, a part of active force is passed to handrail receiving portion 4 by it, by handrail receiving portion 4, impact force passed to vehicle curb girder panel beating, another part is then dissipated by parallel rib, and then effectively achieve the protection to occupant's head.
Pass through simulated collision test; set up the occupant's head time when collision occurs and occupant's head acceleration relation curve; as shown in Figure 5; heavy line represents the impact curve of ceiling endergonic structure in the car of unassembled the present embodiment of vehicle one; fine line represents vehicle and is equipped with the impact curve of ceiling endergonic structure in the car of embodiment one; it can thus be seen that the vehicle of ceiling endergonic structure in setting up car, it is achieved that protection more preferable to occupant's head.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
