Technical Field

[0001] This utility model belongs to the field of automotive seat technology, specifically relating to a zero-gravity seat quick return structure. Background Technology

[0002] Zero-gravity seats, as a method to improve passenger comfort, are widely used in automobiles. To enhance safety, a structure is installed under the seat frame to allow the zero-gravity seat to quickly return to its original position in the event of a frontal collision. While this structure enables the seat to return to its original position quickly, the seat will still be subjected to impact, meaning the passenger will still be impacted, potentially leading to safety issues. Utility Model Content

The quick return structure includes a locking rotation assembly and a locking unlocking assembly. One end of the locking rotation assembly is hinged to any one of the seat frame skeleton, the linkage assembly, or the drive assembly, and the other end of the locking rotation assembly is mounted on the fixed component via an energy-absorbing structure or by direct hinge. The locking unlocking assembly is mounted on the fixed component and can achieve locking of the locking rotation assembly and unlocking after a forward collision.

[0006] Further preferably, the energy-absorbing structure includes a rotating energy-absorbing component for connecting the fixing component and the locking rotating component, the rotating energy-absorbing component including a fixed end for fixing to the fixing component and a rotating end for fixing to the locking rotating component.

[0007] In a further preferred embodiment, the locking rotation assembly is hinged to the fixed assembly, and the energy-absorbing structure includes an energy-absorbing spring disposed between the locking rotation assembly and the fixed assembly.

[0009] Preferably, the driving component adopts a linear driving structure, and the locking rotation component is disposed between the driving component and the fixed component.

[0010] The beneficial effects of this utility model are as follows: It is equipped with a locking and rotating assembly and a locking and unlocking assembly. When the seat is in a zero-gravity state and the car is subjected to a frontal collision, the locking and unlocking assembly can unlock the locking and rotating assembly, allowing it to rotate and return to its zero-gravity state.

Detailed Implementation

[0020] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0021] like Figures 1-8 As shown, a zero-gravity seat quick-return structure is disclosed. The zero-gravity seat mainly consists of a seat frame 100, a linkage assembly 400, and a drive assembly 600. The seat frame 100 is mounted on a fixed assembly 500 via the linkage assembly 400. The drive assembly 600, used to drive the linkage assembly 400 to achieve zero-gravity adjustment, is provided on both the linkage assembly 400 and the fixed assembly 500. The fixed assembly is used to install the entire seat frame and can be mounted on a sliding assembly or the vehicle body as needed. The fixed assembly, seat frame, linkage assembly, and drive assembly are all existing technologies.

[0022] The quick return structure mainly consists of a locking rotation assembly 200 and a locking unlocking assembly 300. One end of the locking rotation assembly 200 is hinged to any one of the components of the seat frame 100, the connecting rod assembly 400, or the drive assembly 600. The other end of the locking rotation assembly 200 is mounted on the fixed assembly 500 through an energy-absorbing structure or by direct hinge. The locking unlocking assembly 300 is mounted on the fixed assembly 500 and can lock the locking rotation assembly 200 and unlock it after a forward collision.

[0023] When the other end of the locking rotation assembly 200 is mounted on the fixed assembly 500 via an energy-absorbing structure, it can absorb the impact and reduce passenger injury when the car is involved in a frontal collision. Of course, as... Figure 8 The locking rotation assembly shown can also be directly hinged to the fixed assembly, enabling the seat to return to its original position more quickly, thereby increasing passenger reaction time. The energy-absorbing structure and the direct hinge structure can be configured as needed.

[0024] The locking and unlocking assembly typically employs a detonator, which can be a pin-type detonator or a cable-type detonator. When the locking and unlocking assembly is a pin-type detonator, the locking rotation assembly can be directly a locking rotation plate, with a locking hole on the locking rotation plate for the pin in the pin-type detonator to be inserted and locked. Figure 1 and Figure 2 As shown. When the locking / unlocking assembly is a cable-operated detonator type, the locking rotation assembly can be set as a ratchet and pawl structure, such as... Figure 3 As shown.

[0025] The drive assembly can be configured as a linear drive structure or a rotary drive structure as needed. When the drive assembly is a linear drive structure, the quick return structure can be located between the link assembly and the fixed assembly, or between the drive assembly and the fixed assembly. When the drive assembly is a rotary drive structure and is located at the rear end of the seat frame, the quick return structure is located between the link assembly and the fixed assembly, and at the front end of the seat frame. Preferably, the quick return structure is located between the drive assembly and the fixed assembly, and between the front and rear hinge points of the drive seat frame.

[0026] like Figure 5 and Figure 6 As shown, the energy-absorbing structure includes a rotating pin 210 mounted on the locking rotating assembly 200, which is hinged to the fixed assembly 500. The fixed assembly 500 has an arcuate groove 510 through which the rotating pin 210 passes, with an interference fit between the rotating pin 210 and the arcuate groove 510. When the locking rotating assembly rotates, it drives the rotating pin to rotate within the arcuate groove. Due to the interference fit, the rotating pin presses against the arcuate groove, thus achieving energy absorption through compression. Preferably, an energy-absorbing sleeve is provided within the arcuate groove to protect the fixed assembly.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the energy-absorbing structure includes a rotating energy-absorbing component 700 for connecting the fixing component 500 and the locking rotating component 200. The rotating energy-absorbing component 700 includes a fixing end for fixing to the fixing component 500 and a rotating end for fixing to the locking rotating component 200. In this case, the rotating energy-absorbing component can be a friction disc.

[0028] like Figure 7 As shown, the energy-absorbing structure includes a breakable energy-absorbing component 800. At this time, the locking rotation assembly 200 is hinged to the fixed assembly 500. The breakable energy-absorbing component 800 is disposed between the locking rotation assembly 200 and the fixed assembly 500. The breakable energy-absorbing component 800 can be broken when the locking rotation assembly 200 rotates, and energy is absorbed through the breakable energy-absorbing component.

[0029] Of course, the energy-absorbing structure can also be set as an energy-absorbing spring. In this case, the locking rotation assembly 200 is hinged to the fixed assembly 500, and the energy-absorbing spring is set between the locking rotation assembly and the fixed assembly. By converting the impact force into elastic force, the impact is buffered, thereby reducing the injury to the passenger. Specifically, the energy-absorbing spring can be set as a disc spring sleeved on the hinge shaft between the locking rotation assembly and the fixed assembly, or it can be a tension spring set between the locking rotation assembly and the fixed assembly.
