The closed space between the outer plate and the inner plate of the automobile door is utilized, the gas generator is arranged, when the automobile is collided laterally, the sensor detonates the gas generator to release high-pressure gas, so that the closed space is filled with the high-pressure gas immediately, the compressive strength of the automobile door is enhanced, and the anti-collision steel beam on the side of the automobile absorbs energy and deforms and plays a role in protection.

Description

car side impact protection door

technical field

The utility model relates to an automobile side impact protection door. the

Background technique

When a car is running, if a traffic accident occurs, in order to prevent people from bumping into the steering wheel, dashboard or car body and being injured, the driver and passengers are generally protected by airbags. However, because the protection of the airbag only protects the front part of the person, if the collision occurs at the side door of the car, the door is relatively weak and easily deformed due to collision, thereby causing injuries to the driver and passengers. the

Contents of the invention

The technical problem to be solved by the utility model is to provide an automobile side impact protection door with multiple protection devices, aiming at improving the safety of the vehicle in side impact. the

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: it includes a gas generator connected with the door for releasing high-pressure gas, the door includes an outer panel and an inner panel arranged oppositely, and is arranged on the door The left panel and the right panel between the outer panel and the inner panel of the door, and the top panel and the bottom panel of the door arranged between the left panel and the right panel; the outer panel of the door, the inner panel of the door, the left panel, A sealed closed space is formed by the right side plate, the top plate of the car door and the bottom plate of the car door; a sensor is arranged in the closed space, and the sensor is connected with the gas generator. the

Further, more than one opening for high-pressure gas to break through is provided beside the vehicle door. the

Further, a protective airbag is provided on the side of the inner panel of the vehicle door. the

Further, anti-collision steel beams are also arranged in the enclosed space. the

The side impact protection car door of the utility model utilizes the closed space between the outer panel and the inner panel of the car door to install a gas generator. The closed space is immediately filled with high-pressure gas, which enhances the compressive strength of the door, and protects the energy-absorbing deformation of the anti-collision steel beam on the side of the car at the same time. the

Description of drawings

Fig. 1 is the schematic diagram of the utility model automobile side impact protection car door. the

Detailed ways

In this embodiment, as shown in FIG. 1, the automobile side impact protection door includes a gas generator (not shown) communicating with the door 1 for releasing high-pressure gas, and the door 1 includes oppositely arranged doors Outer panel (not shown) and car door inner panel 11, and the left side panel 12 and the right side panel 13 that are arranged between the car door outer panel and the car door inner panel 11, and are arranged between the left side panel 12 and the right side panel 13 Between the door top plate 14 and the door bottom plate 15; the outer door panel, the door inner panel 11, the left side panel 12, the right side panel 13, the door top plate 14 and the door bottom plate 15 form a sealed closed space 16; the closed space A sensor (not shown) is arranged in 16, and the sensor is connected with the gas generator. Anti-collision steel beams 2 are also arranged in the enclosed space 16 . Utilize the closed space 16 between the outer panel of the car door and the inner panel of the car door to install a gas generator. When the car collides sideways, the sensor detonates the gas generator to release high-pressure gas, so that the closed space is filled with high-pressure gas immediately. The compressive strength of the car door is enhanced, and the anti-collision steel beam 2 on the side of the car absorbs and deforms while playing a protective role. the

Wherein, more than one opening 17 for high-pressure gas to break through is provided beside the door 1, and the opening 17 guides the gas pressure to the mounting column (not shown) of the automobile. The design of the opening 17 ensures that the door 1 will Opened smoothly. The side on the door inner panel 11 is provided with a protective airbag (not shown), and the high-pressure gas is introduced into the protective airbag on the inner panel of the door to be opened simultaneously to protect the safety of the occupants. the

The side impact protection car door of the utility model utilizes the closed space between the outer panel and the inner panel of the car door to install a gas generator. The closed space is immediately filled with high-pressure gas, which enhances the compressive strength of the door, and protects the energy-absorbing deformation of the anti-collision steel beam on the side of the car at the same time. the

The utility model has been described in detail above. The above description is only a preferred embodiment of the utility model. When it cannot limit the scope of the utility model, all equivalent changes and modifications made according to the scope of the application should be Still belong to the scope covered by the present utility model. the
