[0002] With the development of intelligent connected cars and the change in consumer demand and positioning for cars, cars will no longer be just a means of transportation, but a carrier for improving the quality of life. The smart cockpit has become a "third space" in addition to home and office. As an important part of the smart cockpit, the concept of "zero gravity" seats came into being and has become a new technology that major automakers have focused on in recent years.
[0003] The application of large-angle zero-gravity seats brings up another issue that cannot be ignored - passenger safety. The large-angle zero-gravity seats have a completely different sitting posture from the traditional car sitting posture.

[0031] The movable slider 7 is slidably arranged in the test frame 1 and is threadedly connected with the linear motion mechanism 4, so that the linear motion mechanism 4 drives the movable slider 7 to slide in the test frame 1 to engage with the slide 2, and the movable slider 7 drives the slide 2 to compress the energy storage mechanism 5 through the linear motion mechanism 4 until the elastic lock 8 on the slide 2 is disengaged from the movable slider 7, so that the slide 2 is ejected from one end of the test frame 1 to the other end under the push of the energy storage mechanism 5.
[0032] As another embodiment of the present application, Figure 2As shown, the linear motion mechanism 4 of the present application includes a driving motor 41 and a driving screw 42. The driving screw 42 is rotatably arranged in the middle of the test frame 1. The driving motor 41 is arranged at one end of the test frame 1. The output end of the driving motor 41 is connected to the driving screw 42 through a coupling or a reducer; the moving slider 7 is threadedly connected to the driving screw 42, and the driving motor 41 drives the driving screw 42 to rotate to make the moving slider 7 slide in the test frame 1, thereby pushing the slide 2 to move in the test frame 1.
[0033] See also Figure 5 The lower part of the slide 2 of the present application is provided with an insertion port 21, and the elastic lock 8 is provided on the insertion port 21.

The elastic lock 8 is a magnetic lock. Among them, the magnetic lock also includes a core rod with a wire wound around it, a return spring and a permanent magnet. When the wire is energized, the core rod is magnetically attracted to the permanent magnet, so that the lock rod 81 on the permanent magnet is retracted into the lock seat, so that the lock rod 81 is disengaged from the lock groove 71 to disengage the movable slider 7 from the magnetic lock, thereby disengaging the movable slider 7 from the slide 2.
