Abstract

The utility model proposes a trunk lid assembly of a hydrogen powered vehicle, which comprises a trunk outer plate, a trunk inner plate and a tail fin. The trunk outer plate and the trunk inner plateare directly buckled as one body through a turned-over edge; the tail fin is fixed at the trunk outer plate through bolts and nuts, and at least one combining site at the middle part is provided between the tail fin and the trunk outer plate; the combining side at the middle part of the tail fin is provided with a gas-guide hole which horizontally runs-through, the corresponding position of the trunk outer plate is provided with a through hole, the through hole is end-to-end jointed with the gas-guide hole, a via hole is arranged at the trunk inner plate which corresponds to the position of the through hole at the trunk outer plate. The trunk lid assembly of the hydrogen powered vehicle adopts the structure, the density of hydrogen is low, therefore, the released race hydrogen gas automatically rises to the top of the trunk, and is discharged through the gas-guide hole at the tail fin, and therefore, the gas is prevented from entering the passenger compartment to pollute the air in car, the structure is simple and practical.

Description

A kind of hydrogen car luggage-boot lid assembly

Technical field

The utility model belongs to the automotive body structure technical field, is specifically related to the car trunk cap assembly.

Background technology

Serious day by day along with green-house effect, automotive regulation is also more and more severeer to the emission of automobile wastes standard.Therefore, in order to reduce automobile exhaust pollution, automobile main frame maker all can utilize the driving engine of clean energy resource in research and development.Wherein, hydrogen car is exactly a kind of clean environment firendly automobile, generates water after the fuel combustion, and environment is not had any pollution.But because the procurement cost costliness of hydrogen fuel, and hydrogen fuel is inflammable and explosive, the volume production difficulty.Therefore, how hydrogen car also is in the research and development stage at present.The gas cylinder of a lot of fuel automobiles all is arranged in the baggage container, because the gentle rail of air valve of gas cylinder can not be realized zero sealing, more or less has micro-gas leakage.Present fuel automobile does not consider that fuel gas is discharged problem in the baggage container, causes the pollution to the crew module, has potential safety hazard simultaneously.

Summary of the invention

The utility model is at the deficiency of prior art problem, a kind of hydrogen car luggage-boot lid assembly is provided, the minimum gas that this assembly can make gas cylinder leak is discharged outside the baggage container easily, solves micro-gas leakage and baggage container and the crew module's in-vehicle air pollution problem brought.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is as follows:

A kind of hydrogen car luggage-boot lid assembly, it is made up of baggage container outside plate, baggage container inner panel and empennage, described baggage container outside plate and baggage container inner panel directly are fastened and connected by flange and are one, described empennage is fixedly mounted on the baggage container outside plate by bolt and nut, and a binding site with the baggage container outside plate is arranged at the middle part at least; Be provided with the gas port of lateral direction penetrating in the binding site position at described empennage middle part, and be provided with through hole at the correspondence position of baggage container outside plate, through hole docks with described gas port, and the baggage container inner panel is provided with via hole at the lead to the hole site corresponding to the baggage container outside plate.

Adopt the luggage-boot lid assembly of this kind structure, because the density of hydrogen is low, the micro-hydrogen fuel gas of release rises to the baggage container top automatically, can discharge by the gas port on the empennage, thereby prevent that gas from entering the crew module and causing in-vehicle air pollution, simple and practical.

Wherein, 1-empennage, 2-baggage container outside plate, 3-bolt, 4-gas port, 5-baggage container inner panel, 6-waterproof pad pasting, 7-through hole, 8-via hole

The specific embodiment

Referring to Fig. 1 and Fig. 3, this luggage-boot lid assembly is made up of baggage container outside plate 2, baggage container inner panel 5 and empennage 1, baggage container outside plate 2 and baggage container inner panel 5 directly are fastened and connected by flange, and empennage 1 is installed on the baggage container outside plate 2, and the binding site of three in left, center, right portion and baggage container outside plate 2 is arranged.

The baggage container outside plate and the baggage container inner panel between, the three is connected by being embedded in the bolt on the empennage and the nut of baggage container inner panel one side.

As shown in Figure 2, empennage 1 has M6 bolt 3 at the binding site of itself and baggage container outside plate 2, and they are linked to be an integral body by injection moulding processing and empennage 1.

As shown in Figure 4, be provided with the gas port 4 of lateral direction penetrating in the binding site position at empennage 1 middle part, and be provided with through hole 7 at the correspondence position of baggage container outside plate 2, through hole 7 docks with described gas port 4, and baggage container inner panel 5 also is provided with via hole 8 at the lead to the hole site corresponding to the baggage container outside plate, facilitates discharging via via hole 8, through hole 7 and gas port 4 of the interior hydrogen of baggage container like this.Workman's operation was convenient in the discrepancy of sleeve when the setting of via hole 8 also was convenient to the workman and is assembled.Simultaneously, between the binding site of empennage 1 and baggage container outside plate 2, use waterproof pad pasting 6, prevent that rainwater from entering baggage container by assembly opening.

During assembling, the M6 double-screw bolt 3 on the empennage 1 passes the hole on the baggage container outside plate 2, and the pneumtic impact wrench sleeve passes the via hole 8 on the baggage container inner panel 5, by nut empennage 1 is fixed on the baggage container outside plate 2.

Claims

1, a kind of hydrogen car luggage-boot lid assembly, it is made up of baggage container outside plate, baggage container inner panel and empennage, described baggage container outside plate and baggage container inner panel directly are fastened and connected by flange and are one, described empennage is fixedly mounted on the baggage container outside plate by bolt and nut, and a binding site with the baggage container outside plate is arranged at the middle part at least; It is characterized in that: the gas port that is provided with lateral direction penetrating in the binding site position at described empennage middle part, and be provided with through hole at the correspondence position of baggage container outside plate, through hole docks with described gas port, and the baggage container inner panel is provided with via hole at the lead to the hole site corresponding to the baggage container outside plate.
