Technical Field

The invention relates to the technical field of safety belts, in particular to a safety belt structure, and further relates to a vehicle with the safety belt structure.

Background

In order to fix a driver or the like of a vehicle to a seat, a seatbelt device is provided with an emergency lock mechanism that is driven by a sensor that responds to an emergency acceleration, collision, or deceleration and physically locks a webbing release, thereby being able to safely and effectively fix and protect the driver or the like. However, the conventional seat belt structure adopts a mode of completely fixing the driver and the passenger on the seat when the vehicle is in an emergency, and the seat belt can cause serious injury to the driver and the passenger.

Disclosure of Invention

In view of the above, the present invention is directed to a seat belt structure to provide a certain cushion after the seat belt is locked, so as to protect the driver.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

a safety belt structure is arranged on a vehicle and comprises a safety belt body with a retractor and a mesh belt, wherein the mesh belt has an unlocking state capable of being pulled relative to the retractor and a locking state capable of being locked relative to the retractor; be in locking state the meshbelt drives because of external force the coiler reaches when rotating, the elastic component can be to rotating the elastic tension is applyed to the rotation piece.

Furthermore, the buffering subassembly is for concatenating the multistage that sets up, and all grades the rotation of buffering subassembly is connected via the linkage unit between, by being close to the coiler buffering subassembly extremely keeps away from the coiler buffering subassembly, each grade the buffering subassembly the elastic component is configured to become invalid after providing preset elastic tension in proper order, and is by adjacent the elastic component continues to provide elastic tension.

Furthermore, the rotating part of each level of the buffer assembly is cylindrical and can be rotatably sleeved on a rotating shaft fixedly arranged on the vehicle body; the connecting unit comprises a stop block constructed at one end of the rotating piece and a sliding groove constructed at the end part adjacent to the rotating piece and used for the stop block to slide; when the stop block rotates to abut against the side wall of the sliding groove, the rotating piece can drive the adjacent rotating piece to rotate, and the elastic piece of each buffer assembly provides elastic tension when the rotating piece starts to rotate.

Further, at different levels the buffer unit the rotation piece fixed connection, and by being close to the coiler the buffer unit extremely keeps away from the coiler the buffer unit, each level the buffer unit the elastic component has the redundancy that increases in proper order, each the elastic component can rotate the winding to exert behind the redundancy the elastic tension rotates the piece.

Furthermore, the vehicle body is provided with reels corresponding to the buffer assemblies one by one in a rotating mode, one ends of the elastic parts of the buffer assemblies are wound on the reels, the buffer assemblies are close to the retractor and far away from the buffer assemblies of the retractor, the winding amount of the elastic parts of the buffer assemblies on the reels is sequentially increased, and the winding amount forms the redundancy amount.

Furthermore, each elastic element adopts an elastic belt.

Further, the buffering components are symmetrically arranged on two sides of the retractor.

Further, the seatbelt structure further includes a rotation restricting member configured to constitute a restriction of rotation of the rotating member in a pulling direction of the elastic member.

Further, the rotation limiting assembly comprises a ratchet tooth constructed on the rotating piece and a pawl arranged on the vehicle body and matched with the ratchet tooth.

Compared with the prior art, the invention has the following advantages:

according to the safety belt structure, the rotating part is arranged on the retractor, and the elastic part is arranged between the rotating part and the vehicle body, so that after the mesh belt is locked relative to the retractor, the retractor and the rotating part can still rotate under the pulling of the elastic part, the buffering is provided for a driver and passengers, and the driver and passengers can be protected better.

Another object of the present invention is to propose a vehicle on which a safety belt structure as described above is applied.

The vehicle of the present invention has the same advantages as the above-mentioned safety belt structure, and will not be described in detail herein.
