[0020] The device is improved based on the conventional automobile seat, the front seat is provided with a track on the floor 3 in the vehicle, the track is provided with a seat base 2 which can be manually or electrically adjusted, the conventional automobile seat is directly fixed to the seat base 2, and the utility model sets a sliding seat 4 on the seat base 2, fixes the seat on the sliding seat 4, utilizes the mode that the seat base 2 and the seat body are indirectly connected, and realizes the energy releasing function of the seat.

[0021] Therefore the whole automobile seat is fixed on the sliding seat 4 and supported by the sliding seat 4, therefore the sliding seat 4 and the support structure of the seat bottom are integral rigid structures, rigid strength is required to support the passenger and the seat, high-strength steel material needs to be adopted, in order to further ensure the reliability of the connection between the sliding seat 4 and the automobile seat and avoid the fracture of the connection part between the sliding seat 4 and the automobile seat, at least two support legs which protrude and contact the support rail are arranged at the bottom of the automobile seat, the support leg is in sliding fit with the support rail, and the support leg is started along with the forward and backward movement of the seat, and only needs to not interfere with the seat base 2.

[0022] The sliding seat 4 is in the form of a long strip column structure and is horizontally arranged on the seat base 2, the front and rear of the sliding seat 4 are connected to the front and rear of the seat base 2 through support springs 5, and preferably at least two support springs 5 are arranged on each side, when the support spring 5 is not subjected to force, a pin hole is arranged on the seat base 2 in the locking position of the sliding seat 4, an electric pin 6 which can be raised and lowered is arranged on the sliding seat 4, the electric pin 6 can be inserted into the pin hole when the electric pin 6 is extended (in the normal state), so that the sliding seat 4 is locked on the seat base 2, the electric pin 6 can quickly leave the pin hole when the electric pin 6 is retracted (in the case of collision), so that the unlocking is completed, and then the two support springs 5 on the two sides can support the seat in the collision and release the force by the seat.

[0023] In order to limit the movement range of the sliding seat 4 in the seat base 2 and avoid the upward and downward sliding, the seat base 2 is provided with a sliding groove on each side, and is in the form of an open box structure with an upper turning edge at both ends, the sliding groove on each side is used for embedding the two ends of the sliding seat 4 into the sliding groove, so that the sliding seat 4 can slide along the sliding grooves on the two sides and avoid the upward and downward fluctuation due to the upward and downward fluctuation of the vehicle, and then the electric pin 6 and the pin hole can perfectly realize the locking of the sliding seat 4, and the turning edge structure at both ends can be used for fixing the support spring 5.

[0024] The protection device can also be repeatedly used, because the electric pin 6 can be retracted (the protection function is triggered by collision), and the pin hole is reinserted to complete locking, because the supporting spring 5 can align the position of the electric pin 6 and the pin hole again, and the electric pin 6 can be locked in the pin hole by extending the electric pin 6, and the electric pin 6 can adopt any electric control telescopic structure, and therefore, an electromagnetic electric pin 6 structure (such as a similar structure used on an intelligent door lock) is suggested to be used, the electric pin 6 is in a columnar structure, hollow inside, and provided with an electromagnet at the top, the lock body is located in the hollow structure, and the electromagnet and the lock body are supported by the spring, so that the lock body is extended out of the columnar structure in normal state and inserted into the pin hole in the sliding seat 4, when the electromagnet is powered, the lock body is immediately attracted out, and the lock body is away from the pin hole, so that the whole seat can slide with the sliding seat 4, and is supported by the supporting spring 5, and the reliability of energy dissipation is ensured.
