Description of the embodiments

As shown in fig. 5 to 8, the automobile seat with the one-key unlocking slide rail mechanism comprises a seat cushion assembly 2, a backrest assembly 1, a slide rail 4, a slide rail unlocking rod 3, an angle adjuster, an unlocking mechanism, a poking plate 8 and a guy cable 5. One side of the bottom end of the backrest assembly 1 is hinged with the seat cushion assembly 2 through an angle adjuster. Two slide rails 4 are respectively arranged at the bottom ends of two sides of the seat cushion assembly 2, and the slide rails 4 are connected in the vehicle through a connecting device. The slide rail unlocking rod 3 is arranged on the inner sides of the two slide rails 4, the unlocking mechanism is connected with the angle adjuster, the unlocking mechanism is a one-key unlocking mechanism, and the angle adjuster and the unlocking mechanism are of the existing structure and are not described in detail herein. The plectrum 8 is connected with the angle adjuster core piece through a connecting device, the connecting device is a shaft sleeve 16 connected outside the core piece, the plectrum 8 is connected outside the shaft sleeve 16, and one end of the shaft sleeve 16 is welded with a limiting retainer ring 15. When the angle adjuster is unlocked, the backrest assembly 1 rotates forwards, and in the forward rotation process of the backrest assembly 1, the limit baffle 17 at the lower side of the backrest assembly 1 pushes the shifting piece to swing.

As shown in fig. 6, the whole length of the slide rail unlocking rod 3 is lengthened, the unlocking force arm L2 of the slide rail unlocking rod 3 is 251mm, and L2 is the projection distance from the rotation center 6 of the slide rail unlocking rod 3 to the front end of the slide rail unlocking rod 3. The unlocking force arm L1 of the inhaul cable 5 is 85.7mm, and L1 is the projection distance from the rotation center 6 of the sliding rail unlocking rod 3 to the joint of the inhaul cable 5 and the sliding rail unlocking rod 3.

As shown in fig. 5, 7 and 8, the rear end of the pull rope 5 is connected with the pulling piece 8, and the front end of the pull rope 5 extends forwards to be connected with the slide rail unlocking rod 3. The plectrum is the extension plectrum, and the plectrum bottom extends to the fixed plate 14 edge under the angle modulation ware, and the plectrum is whole to be the auricular structure, and the integrative punching press of sheet metal component that says so forms the structure of similar people's auricular. The sideboard surface fixed connection of plectrum front side is used for fixing a position cable 5 and the cable spring fixed plate 11 of extension spring, and cable spring fixed plate 11 is equipped with the cable guiding hole that extends along the horizontal direction near the downside. The guy cable spring fixing plate 11 comprises a fixing plate and a connecting plate formed by outwards bending and extending the front end of the fixing connecting plate, the fixing plate is fixedly connected to the surface of the side plate through welding, the guy cable guide hole is formed in the position, close to the bottom, of the connecting plate, the tension spring positioning hole is formed in the position, close to the top, of the connecting plate, one end of the tension spring is connected with the poking piece, and the other end of the tension spring is connected with the tension spring positioning hole of the guy cable spring fixing plate 11. The rear end of the stay cable passes through the stay cable guide hole and then is connected with the bottom end of the pulling piece, when the angle adjuster is unlocked, the limiting baffle 17 at the lower side of the backrest assembly 1 pushes the pulling piece to swing, the height of the pulling piece and the stay cable connecting point in the vertical direction is unchanged in the process of swinging the pulling piece back and forth, namely the rear end of the stay cable keeps linear motion, and the travel of the stay cable is optimized. When the unlocking mechanism unlocks the angle adjuster, the backrest assembly 1 rotates forwards, and in the forward rotation process of the backrest assembly 1, the limiting baffle 17 at the lower side of the backrest assembly 1 pushes the shifting block to swing, the shifting block swings to pull the inhaul cable to move forwards and backwards on the same straight line along the inhaul cable guide hole, and the inhaul cable pulls the sliding rail unlocking rod 3 to unlock the sliding rail. In fig. 7, B1 is an initial position of the pulling piece, B2 is a position after the pulling piece is unlocked, A1 is a position before the pulling rope is unlocked, and A2 is a position after the pulling rope is unlocked. The fixed plate of cable and extension spring unites two into one and sets up in plectrum front side, not only the intensity of fixed plate that strengthens, and plectrum rear side no longer is equipped with the extension spring fixed plate at this moment, reserves back travel baffle backward upset space, like the K department position in fig. 7, can satisfy new platform demand.

The front end of the inhaul cable passes through the lower part of the seat cushion assembly and then extends downwards to be connected with the slide rail unlocking rod 3. The specific connection mode is as follows, and the front end downside of seat pad assembly is connected with cushion cable fixed plate 10, and cushion cable fixed plate 10 below is equipped with slide rail cable fixed plate 13. The slide rail cable fixing plate 13 is fixedly connected with the slide rail unlocking rod 3 through a connecting device, the front end of the cable extends forwards to the position of the seat cushion cable fixing plate 10 and then downwards passes through the seat cushion cable fixing plate 10, and the cable continues to extend downwards to be connected with the slide rail cable fixing plate 13. The extending direction of the stay cable between the pad stay cable fixing plate and the slide rail stay cable fixing plate 13 is the P direction, the connecting line of the stress points of the slide rail stay cable fixing plate 13 before and after unlocking coincides with the P direction, as shown in fig. 8, the position C1 in the figure is the position before unlocking the slide rail stay cable fixing plate 13, and the position C2 is the position after unlocking the slide rail stay cable fixing plate 13. The extension direction of the inhaul cable and the connecting line of the stress points of the slide rail inhaul cable fixing plate 13 before and after unlocking are in the same straight line, and the inhaul cable unlocking force is totally applied to the slide rail inhaul cable fixing plate 13, so that the inhaul cable locking force is not decomposed, and the inhaul cable unlocking force is smaller.

After the structure is adopted, the inhaul cables are reasonably arranged, the inhaul cable unlocking force is reduced, and the one-step unlocking synchronism is higher; and the welding space of the parts is reasonably arranged, the use of the parts is reduced, the size of the slide rail unlocking rod 3 is prolonged, and the slide rail unlocking operation comfort is further improved. Through the test, the unlocking force of the front end of the sliding rail is reduced from 100N to 79N, and the unlocking force of the inhaul cable for unlocking the sliding rail is reduced from 365.6N to 232N. The backrest assembly 1 is unlocked through the angle adjuster, when the angle adjuster is unlocked through the unlocking mechanism, the backrest always rotates forwards, the limiting baffle 17 pushes the pulling piece to swing, the pulling piece swings to pull the pull rope, the pull rope pulls the slide rail unlocking rod 3, the backrest assembly 1 is turned forwards to unlock the slide rail at 35 degrees, the backrest is convenient for passengers to enter/exit, the position A of the backrest before unlocking is shown in fig. 5, and the position B of the backrest after unlocking is shown.

The above embodiments are merely preferred embodiments of the present utility model, the structure of the present utility model is not limited to the forms of the above embodiments, and any modifications, equivalents, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
