In this embodiment, the guide groove 1.1 has a structure with a predetermined radian and is similar to an L shape, wherein the vertical arc groove is a turnover range of the seat, the joint of the vertical arc groove and the transverse arc groove is an unlocking part, the transverse arc groove is a locking part, and meanwhile, the transverse arc groove plays a role in locking and guiding the movement of the seat along the guide rail 5, the seat can be kept in an open state while stable locking, the problem of dead point failure is solved, and parameters such as radian and arc length of the vertical arc groove and the transverse arc groove can be calculated according to the turnover track of the seat. The guard plate 4.2 is provided with a transverse groove and a second mounting hole which are arranged up and down, and the transverse groove corresponds to the transverse arc groove of the guide groove 1.1 in position. Preferably, the stroke angle of the vertical arc groove of the guide groove 1.1 is 30-50 degrees, so that the seat can be turned over by 30-50 degrees, the space requirement of passengers for getting on and off the vehicle can be met by the angle, the turning and moving process of the seat is saved, the groove widths of the transverse arc groove and the vertical arc groove are designed according to the outer diameter of the lock pin 11, and the lock pin 11 can be completely locked to ensure that the seat can be turned over in a preset posture and simultaneously does not generate resistance to the lock pin 11.

The skeleton mounting plate 1 is connected with the mounting bracket main body 4.1 of the mounting bracket 4 through the first mounting hole 1.2 by a step bolt 12 and is locked by a nut 13. The locking plate 2 is arranged outside the guard plate 4.2, and the locking plate 2 is provided with through holes corresponding to the transverse grooves and the second mounting holes on the guard plate 4.2 respectively. The locking plate 2 is connected to the guard plate 4.2 by means of a combination of a step bolt 12, a second mounting hole and a through hole and a nut 13, and the locking plate 2 can rotate around the step bolt 12 relative to the guard plate 4.2.

When the skeleton mounting plate 1 rotates around the step bolt 12, the lock pin 11 moves along the guide groove 1.1, overturning guide of the skeleton mounting plate 1 is achieved until the lock pin 11 enters the locking part in the guide groove 1.1, and the swing clearance of the seat can be reduced by utilizing effective locking of the lock pin 11 in the embodiment.

The slide rail 5 is composed of an upper slide rail and a lower slide rail, and the upper slide rail can slide on the lower slide rail. The front end of the bottom of the mounting bracket 4 is mounted on an upper sliding rail through bolts, and a lower sliding rail is fixedly mounted on a cross beam and a floor of a vehicle.

The front end of the lower side part of the mounting bracket 4 is connected with the locking plate 2 through the first return spring 3 to form a return locking force of the locking plate 2, the locking of the locking plate 2 can be realized under the action of resilience force of the first return spring 3, and abnormal noise generated by shaking of a seat in the running process of a vehicle can be avoided.

The first return spring 3 can be realized by combining a hook at the end part with a connecting hole arranged at the front end of the locking plate 2. The first return spring 3 is always in an elongated state, and the first return spring 3 is gradually pulled longer from the elongated state when the occupant turns over the seat. The framework mounting plate 1 gradually overturns and lifts, and the locking plate 2 enters a locking position under the action of the first return spring 3, so that locking is realized.

The locking plate 2 is driven by the first return spring 3 to rotate anticlockwise, so that the locking pin 11 is driven to move downwards along the vertical arc groove of the guide groove 1.1, and the locking pin 11 can be prevented from rebounding upwards under the acting force of the first return spring 3. When the lock pin 11 enters the transverse arc groove to enable the lock plate 2 to be locked at the locking position, the seat framework structure is automatically locked through the first return spring 3, and abnormal sound generated by rocking of the seat can be avoided while overturning return is avoided.

The fixed point unlocking structure is used for unlocking the seat, so that the seat can be switched between a translational state and a turnover state, and as shown in fig. 4, the fixed point unlocking structure comprises a poking pin 6, a second return spring 7, a poking block 8, a mounting plate 9, a rotating pin 10 and a rotating sleeve 14.

The mounting plate 9 comprises a flat plate with a concave side and a side plate vertically upwards along the end part of the concave area, and the side plate has a trapezoid-like structure. The mounting plate 9 is riveted on the lower rail of the rail 5 by rivets using the non-concave side of the flat plate. The shifting block 8 is riveted with the center of the upper part of the side plate of the mounting plate 9 through the rotating pin 10, the second return spring 7 is sleeved on the rotating pin 10 between the shifting block 8 and the side plate and is connected with the shifting block 8 and the mounting plate 9, the shifting block 8 can be reset under the action of the resilience force of the second return spring 7, and abnormal sound caused by shaking of the shifting block 8 in the running process of a vehicle can be avoided. The concave area on the mounting plate 9 in this embodiment can avoid the second return spring 7 damaging the mounting plate 9 when the dial 8 rotates.

In this embodiment, the upper and lower ends of the shifting block 8 are respectively higher than the end of the mounting plate 9, and the height of the upper end of the shifting block is matched with the bottom end of the locking plate 2, so as to realize shifting between the locking plate 2 and the shifting block 8, and when the lower end of the shifting block 8 abuts against the rear side end of the mounting plate 9, the limiting of the shifting block 8 in the vertical state can be realized. The side edge of the shifting block 8 far away from the mounting plate 9 is L-shaped, when the locking plate 2 and the shifting block 8 are mutually shifted, the side edge is connected with the locking plate 2, and the corner of the side edge is an arc corner with a certain radian, so that the resistance of the locking plate 2 when shifting the shifting block 8 can be reduced. When the dial block 8 is riveted with the rotating sleeve 14 through the poking pin 6 in the center of the area of the upper end of the dial block 8 higher than the side plate and the locking plate 2 and the dial block 8 poke each other, the rotating sleeve 14 converts static friction into rotating friction, unlocks friction force and reduces abrasion.

As shown in fig. 5, when the passenger drives the skeleton mounting plate 1 to rotate anticlockwise around the step bolt 12, the first return spring 3 is lengthened, the locking plate 2 rotates anticlockwise around the step bolt 12 under the action force of the first return spring 3, the locking plate 2 drives the locking pin 11 to move downwards along the vertical arc groove of the guide groove 1.1, and when the locking plate 2 abuts against the shifting block 8, the locking pin 11 enters the unlocking part of the guide groove 1.1, so that the seat keeps a forward overturning posture. At this time, when the seat moves forward in a translational manner, the lock pin 11 moves along the transverse groove and the transverse arc groove, and the lock plate 2 toggles the shifting block 8 to rotate anticlockwise, so that the seat can slide forward continuously, and the space for the passengers in the rear row to enter and exit is further increased. When a passenger drives the seat to move backwards, after the shifting block 8 touches the locking plate 2, the locking plate 2 is shifted to rotate, when the locking plate 2 is separated from the shifting block 8, the framework mounting plate 1 is turned clockwise again, at the moment, the lock pin 11 enters the vertical arc groove of the guide groove 1.1 of the framework mounting plate 1 to be separated from locking, the first return spring 3 is reset, and the framework mounting plate 1 is rotated clockwise to be in a ridable position. During the forward and backward translation of the seat, the lock pin 11 moves along the transverse groove of the guard plate 4.2 and the transverse arc groove of the guide groove 1.1, so that the seat is ensured to move stably.
