Description
Technical Field
[0001] This utility model belongs to the field of automotive seats, specifically relating to a zero-gravity mechanism for automotive seats driven by a slide rail. 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 industry. Zero-gravity seats aim to adjust the angle and position of the seat so that the passenger's body is subjected to even pressure, approaching a state of weightlessness, thereby reducing pressure on various parts of the body, alleviating fatigue, and improving ride comfort. Currently, there are various ways to implement zero-gravity seats on the market, but they generally have some problems. The adjustment mechanisms of some zero-gravity seats are complex, which not only increases production costs and manufacturing difficulty but also makes them prone to malfunction, reducing the reliability and stability of the seat. Some adjustment mechanisms exhibit jamming or unevenness during adjustment, failing to achieve precise and smooth adjustment, affecting the user experience and posing safety hazards.
[0003] Chinese patent CN 218141165 U (application number 2022220757368) discloses "A Zero Gravity Seat Driven by a Slide Rail", which provides a zero gravity seat structure driven by a slide rail. However, it has the following disadvantages: 1) The drive structure of this structure is arranged on the slide rail assembly at the bottom of the seat, which will have a certain impact on the overall front and rear adjustment range of the seat; 2) The slide rail structure used in this structure is relatively long, and the overall cost is relatively high. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0019] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. 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.
[0020] like Figures 1 to 3As shown, this embodiment provides a zero-gravity mechanism for a car seat driven by a slide rail, including a slide rail bracket 1 mounted on the slide rail, a zero-gravity slide rail assembly 2 disposed between the left and right slide rail brackets, a front zero-gravity LINK component 4 with one end rotatably connected to the zero-gravity slide rail assembly 2 and the other end rotatably connected to the seat cushion side plate 3, and a rear zero-gravity LINK component 6 with one end rotatably connected to the slide rail bracket 1 and the other end rotatably connected to the rear crossbar 5; wherein, the slide rail bracket 1 is provided with a motion groove 101 at a position opposite to the zero-gravity slide rail assembly 2; The zero-gravity slide rail assembly 2 includes a lead screw base 201 installed inside the slide rail bracket 1, a zero-gravity slide rail lead screw 202 installed on the lead screw base, and a slide rail motor assembly 203. The slide rail motor assembly 203 is mounted on the zero-gravity slide rail lead screw 202 and moves along the zero-gravity slide rail lead screw 202. The zero-gravity slide rail bracket 2032 on the slide rail motor assembly 203 is rotatably connected to the front zero-gravity LINK component 4, and the shaft at the connection point is placed in the motion groove 101 of the slide rail bracket 1, and can move along the motion groove 101.
[0021] In this embodiment, the slide rail motor assembly 203 includes a zero-gravity motor assembly 2031 that moves along the zero-gravity slide rail lead screw, zero-gravity slide rail brackets 2032 disposed at both ends of the zero-gravity motor assembly 2031, and a motor bracket assembly 2033 disposed between the left and right zero-gravity slide rail brackets 2032; wherein, the zero-gravity motor assembly 2031 is fixed on the motor bracket assembly 2033.

[0023] Working principle: When the zero gravity switch is turned on, the zero gravity motor assembly receives a signal, driving the slide rail motor assembly to move along the zero gravity slide rail screw. At the same time, the connection between the zero gravity slide rail bracket and the front zero gravity LINK component moves along the movement groove of the slide rail bracket. The rotation of the front zero gravity LINK component lifts the front half of the seat cushion upward, thus achieving a zero gravity posture for the seat. This structure can be stopped at any time within the zero gravity slide rail stroke to meet the needs of different passengers. Adjusting the entire structure through the slide rail provides higher stability and greater safety and reliability.
