Abstract
The utility model relates to the technical field of automobile parts, in particular to a dual-buffering air aseismic airbag. The dual-buffering air aseismic airbag comprises a cover plate and rubber members, wherein the rubber members are arranged at the lower end of the cover plate in a matching mode; a piston is arranged on the lower parts of the rubber members; a buffer device is arranged in the piston and comprises a contact block fixedly adhered to the inner wall of the cover plate; an air through hole is formed in the contact block; a pneumatic expansion rod is correspondingly arranged on the contact block; a sealing plug is arranged at the bottom of the piston; and a through hole opposite to the air through hole is formed at the bottom of the sealing plug. By the dual-buffering air aseismic airbag, the buffer device is arranged inside the piston, so that an inner rubber member contacts the buffer device arranged inside the piston when the cover plate is pressed downwards by strong external force; and the buffer device transmits the gas through the through hole to ensure that air current input to the pneumatic expansion rod through the through hole forms atmospheric pressure and the buffer device is resilient, so that an outer rubber member is difficultly broken to achieve the aim of internally and externally buffering.
Description
Technical field
The utility model relates to technical field of automobile parts, especially relates to a kind of pair of air damping air bag.
Background technique
At present, the shock absorber of automobile is rubber parts.Generally speaking under automobile is under pressure situation, its cover plate can be stressed to pressing down, therefore this moment, rubber parts cushioned downforce because of with resilience, the cover plate that slows down presses down speed, yet rubber parts is to form by the rubber heat seal, though certain elastic force is arranged, but after pressure surpasses the maximum compressive strength of rubber parts, rubber parts is broken, and in a single day rubber parts break and just can not reach the effect of buffering.
The model utility content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of pair of air damping air bag, and it has and is difficult for making outside rubber parts to break, and reaches the inside and outside characteristics that can both cushion.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of pair of air damping air bag, comprise cover plate and cooperate the rubber parts of being located at the cover plate lower end, described rubber parts bottom is provided with piston, the in-built damping device that is equipped with of piston, and described damping device comprises the contact block that fixedly is attached at the cover plate inwall, described contact block offers vent, the contact block correspondence is provided with the Pneumatic extension bar, and described piston base is provided with sealing plug, and the sealing plug bottom offers the through hole corresponding with vent.
Wherein, described flexible rod comprises the first flexible rod of being located at upper end in the piston, is arranged with the second flexible rod in the first flexible rod, and Packed contact plate is established in the second flexible rod upper end, is provided with seal ring between the first flexible rod and the second flexible rod.
After adopting said structure, the utility model is compared with existing technology the advantage that has: it comprises cover plate and cooperates the rubber parts of being located at the cover plate lower end, described rubber parts bottom is provided with piston, the in-built damping device that is equipped with of piston, described damping device comprises the contact block that fixedly is attached at the cover plate inwall, and described contact block offers vent, and the contact block correspondence is provided with the Pneumatic extension bar, described piston base is provided with sealing plug, and the sealing plug bottom offers the through hole corresponding with vent; The utility model is by having damping device at the internal piston device, be subject to the damping device that very strong external force rubber parts of inside when pressing down can touch internal piston when cover plate like this, damping device is by the through hole gas transmission, when rubber parts touches the damping device of internal piston, make the air-flow formation atmospheric pressure and the resilience that are input to the Pneumatic extension bar by through hole, be difficult for like this making outside rubber parts to break, therefore can reach the inside and outside effect that can both cushion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, cover plate; 2, rubber parts;
3, piston; 4, contact block;
5, vent; 6, through hole;
7, the first flexible rod; 8, the second flexible rod;
9, sealing plug.
Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
As shown in Figure 1: a kind of pair of air damping air bag, comprise cover plate 1 and cooperate the rubber parts 2 of being located at cover plate 1 lower end, described rubber parts 2 bottoms are provided with piston 3, the piston 3 in-built damping devices that are equipped with, described damping device comprises the contact block 4 that fixedly is attached at cover plate 1 inwall, described contact block 4 offers vent 5, contact block 4 correspondences are provided with the Pneumatic extension bar, described piston 3 bottoms are provided with sealing plug 9, sealing plug 9 bottoms offer the through hole 6 corresponding with vent 5, the utility model is by having damping device at piston 3 interior arrangements, be subject to the damping device that very strong external force rubber parts 2 of inside when pressing down can touch piston 3 inside when cover plate 1 like this, damping device is by through hole 6 gas transmissions, when rubber parts 2 touches the damping device of piston 3 inside, make the air-flow formation atmospheric pressure and the resilience that are input to the Pneumatic extension bar by through hole 6, be difficult for like this making outside rubber parts 2 to break, therefore can reach the inside and outside effect that can both cushion.
In the present embodiment, described flexible rod comprises the first flexible rod 7 of being located at piston 3 interior upper ends, be arranged with the second flexible rod 8, the second flexible rods 8 upper ends in the first flexible rod 7 and establish Packed contact plate, be provided with seal ring between the first flexible rod 7 and the second flexible rod 8, described contact plate is the plate body of integral sealing, it mainly is the upper end of shutoff flexible rod, make to form sealing in the flexible rod, but stay section offer through hole 6, for the flexible rod inflation forms air pressure, reach the effect of buffering.
The above only is better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
