Description

Technical Field

[0001] This utility model belongs to the field of automotive seats, specifically relating to a zero-gravity structure for automotive seats that can achieve high-adjustment via an angle adjuster drive. Background Technology

[0002] As people's demands for car ride comfort continue to increase, zero-gravity seats have gradually become a research hotspot in the automotive seating field. Zero-gravity seats aim to adjust the seat angle and position to ensure that passengers experience even pressure on all parts of their body, approaching a weightless state, thereby effectively reducing fatigue during long journeys. Currently, some zero-gravity seats on the market have complex structures and numerous components, which not only increases production costs and assembly difficulty but also reduces the reliability and stability of the system. Some seat adjustment mechanisms have slow response speeds, making it difficult to quickly and accurately achieve a zero-gravity state. Some zero-gravity seats with quick-reset functions do not consider smoothness during quick reset, which can easily cause injury to passengers due to sudden reset, and they also do not simultaneously include seat height adjustment functionality. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a zero-gravity structure for car seats that can be adjusted by a height adjuster. It adopts a five-link structure, which can adjust and reset the zero-gravity posture of the seat through a height adjuster and a quick return mechanism while satisfying the seat cushion height adjustment function. It has the advantages of stable and reliable structure, high adjustment accuracy and fast response speed.

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

[0005] A zero-gravity structure for a car seat, driven by an adjuster, enables high-adjustment. It includes a seat cushion side panel, a zero-gravity front support, a quick-return mechanism, an adjuster connecting plate assembly, an adjuster, a synchronizing rod, a zero-gravity motor assembly, a slide rail bracket, and a rear linkage bracket. The front end of the seat cushion side panel is hinged to the zero-gravity front support, and the other end of the zero-gravity front support is hinged to the rotating part of the quick-return mechanism. The fixed part of the quick-return mechanism is integrated with the adjuster via the adjuster connecting plate assembly. The two ends of the synchronizing rod are respectively... The zero-gravity motor assembly is connected to the seat adjusters on both sides of the slide rail bracket; the slide rail bracket is used to drive the synchronous rod to rotate; the slide rail bracket is set on the seat slide rail, and the rear end of the slide rail bracket is hinged to the rear linkage bracket.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0019] like Figures 1 to 5 As shown, this embodiment provides a zero-gravity structure for a car seat with adjustable height, driven by an adjuster. It includes a seat cushion side panel 1, a zero-gravity front support 2, a quick-return mechanism 3, an adjuster connecting plate assembly 4, an adjuster 5, a synchronizing rod 6, a zero-gravity motor assembly 7, a slide rail bracket 8, and a rear linkage bracket 9. The front end of the seat cushion side panel 1 is hinged to the zero-gravity front support 2, and the other end of the zero-gravity front support 2 is hinged to the rotating part of the quick-return mechanism 3. The fixed part of the quick-return mechanism 3 and the adjuster 5 are connected as one unit via the adjuster connecting plate assembly 4. The synchronizing rod 6... Both ends pass through the slide rail bracket 8 and are connected to the seat adjusters 5 on both sides of the seat; the zero gravity motor assembly 7 is used to drive the synchronous rod 6 to rotate; the slide rail bracket 8 is set on the seat slide rail A, and the rear end of the slide rail bracket 8 is hinged to the rear linkage bracket 9. A rear crossbar 10 is provided between two opposite rear linkage brackets 9. The end of the rear crossbar 10 is connected to the rear end of the seat cushion side plate 1. The quick return mechanism 3, together with the seat cushion side plate 1, the zero gravity front bracket 2, the slide rail bracket 8 and the rear linkage bracket 9, forms a five-bar structure. The zero gravity adjustment and height adjustment of the car seat can be completed through the five-bar structure.

[0020] In this embodiment, the quick return mechanism 3 can adopt an existing structure. The quick return mechanism includes a fixed part, a rotating part disposed on the fixed part and rotatable relative to the fixed part, a cam locking plate for locking the rotating part on the fixed part so that the rotating part and the fixed part move as a unit, and a detonator for driving the cam locking plate to unlock the rotating part from the fixed part, allowing the rotating part to rotate freely. The rotating part is provided with an unlocking bracket. When the unlocking bracket engages with the teeth on the fixed part, the rotating part and the fixed part move synchronously. When the unlocking bracket separates from the teeth on the fixed part, the rotating part can rotate freely relative to the fixed part. The detonator (unmarked) is connected to the cam locking plate via a pull wire, and the cam locking plate controls the engagement or disengagement of the unlocking bracket from the teeth on the fixed part.

[0021] Furthermore, in this embodiment, the fixing plate of the angle adjuster 5 is mounted on the side support arm 81 of the slide rail bracket 8. The side support arm 81 is provided with a limiting notch (unmarked). The rotating plate of the angle adjuster 5 is provided with a limiting stop 51 that matches the limiting notch, thereby limiting the maximum adjustment angle of the seat cushion.

[0022] In this invention, when the seat controller receives a zero-gravity posture adjustment signal, the zero-gravity motor assembly 7 drives the two side adjusters 5 to rotate via the synchronizing rod 6. When the adjusters 5 rotate, the quick return mechanism 3 rotates upward synchronously (the rotating part is locked on the fixed part), pushing the front of the seat cushion side plate 1 upward through the zero-gravity front bracket 2, thereby realizing the adjustment of the seat's zero-gravity posture. When an emergency occurs and the seat needs to be reset, the seat controller controls the detonator to unlock the rotating part of the quick return mechanism 3 from the fixed part. At this time, the rotating part rotates, driving the seat cushion side plate 1 to reset. The five-bar linkage design allows the seat to return to a safe posture as quickly as possible while maintaining smoothness, avoiding injury to passengers due to sudden reset. When the seat cushion height needs to be adjusted, the five-bar linkage structure can be driven by an additional high-adjustment motor (the high-adjustment motor can drive the rear crossbar 10 to rise and fall by driving the rear linkage bracket 9), thereby realizing the adjustment of the seat cushion height.

[0023] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
