Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a seat cushion lifting mechanism of a zero-gravity seat driving energy absorption mechanism. Background Art

[0002] Today's zero-gravity seats are an innovative type of comfort seat. When using a zero-gravity seat, the occupants can adjust the seat to achieve a large-angle lying position, which brings a more comfortable sitting position. However, due to the large backrest angle of the zero-gravity seat, the occupants are in a lying position, and the adjustment range of the seat belt is limited. In an emergency, the restraint force of the seat belt on the body is not enough to fully provide protection for the occupants, posing a safety hazard. For example, patent number 2024207061787 discloses a zero-gravity seat basin collision energy absorption locking mechanism. This patent can enable the seat in a zero-gravity posture to return to the appropriate backrest angle and seat cushion angle according to a predetermined route through an energy absorption mechanism after a collision, and after the seat returns to the designed position, the energy absorption mechanism system can reversely lock, greatly reducing the damage to the occupants caused by the inertia after the seat has a large-angle collision. Optimize the sitting posture to improve the restraint protection of the occupants. However, since most existing zero-gravity seat basins use a connecting rod lifting mechanism for lifting, this method not only has the problem of a small seat cushion lifting angle, but also has the problem of proneness to failure due to the complex connecting rod lifting structure. Summary of the invention

[0003] In view of the above problems, an object of the present invention is to provide a seat cushion lifting mechanism of a zero-gravity seat driving energy absorption mechanism, which is used to control the lifting of the seat cushion through a recliner lifting mechanism to overcome the above-mentioned deficiencies of the prior art.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] A seat cushion lifting mechanism of a zero-gravity seat driving energy absorption mechanism comprises: a seat support seat, a seat cushion installed on the seat support seat, a seat cushion energy absorption locking mechanism symmetrically installed on the seat cushion for rapid return of the seat cushion, and a seat cushion lifting mechanism connecting the seat cushion energy absorption locking mechanism and the seat support seat, wherein one end of the seat cushion is hinged to the seat support seat, and the other end is connected to the seat cushion lifting mechanism through the seat cushion energy absorption locking mechanism, and the seat cushion lifting mechanism drives the seat cushion energy absorption locking mechanism and the zero-gravity seat cushion to lift, and the improvement made is that the seat cushion lifting mechanism comprises: two symmetrically arranged seat cushion angle adjustment mechanisms The seat cushion recliner assembly comprises a recliner and a fixing plate, a recliner lower connecting plate of the recliner is fixedly connected to a seat support seat, an recliner upper connecting plate of the recliner is fixedly connected to a seat cushion energy absorption locking mechanism through a fixing plate, the angle adjustment drive motor drives the two seat cushion recliner assemblies to rotate synchronously through the synchronous rod, and the recliner drives the seat cushion angle adjustment through the seat cushion energy absorption locking mechanism.

[0006] As a preferred embodiment of the present invention, a travel stop pin is provided on one side of the upper connecting plate of the recliner close to the lower connecting plate of the recliner, and a travel limit groove is provided on the lower connecting plate of the recliner, one end of the travel stop pin is placed in the travel limit groove, and the travel limit groove is used to limit the angle adjustment stroke of the seat cushion.

[0007] The advantages and positive effects of the present invention are:

[0008] 1. The seat cushion lifting mechanism of the present invention adopts the same adjustment method as the backrest angle adjustment, that is, the seat cushion is driven to adjust the angle through the recliner assembly. Since the structure of the recliner assembly is simpler, the arrangement of the zero-gravity seat cushion is more flexible and convenient.

[0009] 2. The seat cushion lifting mechanism in the present invention applies the recliner assembly to the seat cushion of the zero-gravity seat. The recliner assembly cooperates with the seat cushion energy absorption locking mechanism so that when the seat collides in the zero-gravity posture position, the seat cushion can quickly return to its original position, thereby improving the restraint protection for the occupants and reducing the damage caused by the collision.
