Description

Technical Field

[0001] The present invention relates to the technical field of vehicle safety, and in particular to an in-vehicle safety protection device. Background Art

[0002] The in-vehicle safety protection device is designed to minimize casualties and vehicle damage in traffic accidents by combining active prevention with passive protection.

[0003] Airbags, a core component of the passive safety system, rapidly deploy to form a cushion in a collision, reducing occupant casualties. When a vehicle collides, the sensor sends a signal to the control unit, which in turn sends a signal to the detonator. The spark plug in the detonator ignites the explosive charge, generating high-temperature, high-pressure gas. This gas fills the airbag within 30 milliseconds and ejects from the steering wheel, protecting the occupant's head or neck. However, airbags can deploy at speeds of up to 300 kilometers per hour, creating an impact force equivalent to a 180-pound object hitting the human body. If a passenger is too close to the airbag, the rapidly deploying airbag could directly strike the head, neck, or chest, causing whiplash, a sternal fracture, or facial abrasions.

[0004] The inventors discovered at least the following problems during the implementation of this embodiment:

[0005] The deployment of the existing in-vehicle safety protection device, the airbag, can easily cause secondary injuries to the occupants. Summary of the Invention

[0006] The purpose of the present invention is to provide an in-vehicle safety protection device, which solves the technical problem that the deployment of the airbag in the existing in-vehicle safety protection device easily causes secondary injuries to the occupants.

[0007] Invention solution:

[0008] The present invention provides an in-vehicle safety protection device, comprising a steering wheel assembly and a seat assembly; the steering wheel assembly comprises a turntable, a support seat, an airbag, a protection assembly and a cover body; the support seat is fixedly connected to the turntable, and a first mounting slot, a second mounting slot, a plurality of third mounting slots and a plurality of rope holes are provided at the center of the support seat; the first mounting slot is communicated with the second mounting slot, and the rope holes are respectively communicated with the second mounting slot and the third mounting slot; the airbag is installed in the first mounting slot; the protection assembly comprises a flexible pad, a plurality of limiting ropes and a plurality of rope supporting members; one end of the limiting rope is fixedly connected to the flexible pad, and the other end of the limiting rope is fixedly connected to the rope supporting member, and is passed through the rope hole; the rope supporting member is installed in the third mounting slot; the seat assembly comprises a seat body and a slide rail member; the seat body is provided with a limiting groove, and the slide rail member is provided with a limiting protrusion; the seat body is slidably connected to the slide rail member, and the limiting protrusion is arranged in the limiting groove; the cover body is hinged to the support seat.

[0009] Furthermore, the support seat is provided with a plurality of fixing rings, and the fixing rings are sleeved on the limiting ropes and are located in the second installation grooves.

[0010] Furthermore, the support seat is provided with a hinge column, and the cover body is provided with a hinge hole, and the hinge hole is adapted to the hinge column.

[0011] Furthermore, the cover body is provided with an arc-shaped limiting block.

[0012] Furthermore, the airbag is provided with a plurality of concave edges, and the concave edges correspond to the limiting ropes.

[0013] Furthermore, the rope supporting member is provided with an arc-shaped rope installation groove.

[0014] Furthermore, the limiting ropes are provided with roots, which are equidistantly distributed relative to the flexible pad.

[0015] Furthermore, the limiting ropes are respectively elastic limiting ropes and rigid limiting ropes.

[0016] Furthermore, the limit protrusion is provided with a sound alarm and a touch switch, and the touch switch is electrically connected to the sound alarm.

[0017] Beneficial Effects: The present invention provides an in-vehicle safety protection device. When the vehicle is hit by a collision, the airbag deploys and pushes open the cover. During the expansion process, a limit rope extends from the rope support member to limit the center of the airbag, reducing the impact force on the occupant. The contact position between the end of the limit protrusion and the limit groove is slightly larger than the maximum sliding distance of the vehicle seat body under normal conditions. When the vehicle is hit by a collision, the seat is further limited, preventing the occupant's head and neck from moving significantly, thereby reducing secondary damage caused by the airbag. Therefore, with this in-vehicle safety protection device, the deployment of the airbag is less likely to cause secondary damage to the occupant. BRIEF DESCRIPTION OF THE DRAWINGS
