Detailed Description

As shown in fig. 1 to 5, the mechanical automatic turning device for the automobile without resetting comprises a ground 17 and a circular guide rail 4 mounted on the ground 17, wherein grooves are symmetrically formed in the side wall of the ground, a turning turntable 1 is mounted on the circular guide rail 4, and the turning turntable 1 can rotate relative to the ground 17 through the circular guide rail 4. The symmetrical division of 1 lateral wall of turn round carousel has a pair of hole, downthehole from locking lever (a)3 and from locking lever (b)2 respectively, from locking lever (a)3 with from locking lever (b)2 respectively through a compression spring (a)19 and compression spring (b)18 with turn round carousel 1 links to each other, from locking lever (a)3 and from locking lever (b)2 can be downthehole flexible to drive compression spring along axial motion. Meanwhile, a pair of pressing pedals (a)5 and a pair of pressing pedals (b)6 are symmetrically arranged on the U-turn turntable 1, and the pressing pedals (a)5 and the pressing pedals (b)6 can respectively move up and down relative to the U-turn turntable 1 and rotate together with the U-turn turntable 1. The lower sides of the pair of press-down pedals are fixedly connected with a circular sliding rail (a)7 and a circular sliding rail (b)8 respectively, and the circular sliding rail (a)7 and the circular sliding rail (b)8 move or rotate together with the connected press-down pedals respectively. The pair of circular slide rails are respectively provided with a wedge-shaped slide block (a)9 and a wedge-shaped slide block (b)10, and the wedge-shaped slide blocks (a)9 and the wedge-shaped slide blocks (b)10 respectively move up and down with the connected circular slide rails but can rotate relatively. And two sides of each wedge-shaped sliding block are respectively provided with a limiting support (a)13, a limiting support (b)14, a limiting support (c)15 and a limiting support (d)16, the four limiting supports are fixedly connected with the ground 17 and cannot rotate or move, and the limiting supports are used for limiting the rotation of the wedge-shaped sliding blocks, so that the wedge-shaped sliding blocks can only move up and down and cannot rotate. The lower sides of the wedge-shaped sliding blocks are respectively matched with two ends of a rotating rod 12 through inclined planes, one of the wedge-shaped sliding blocks descends, the rotating rod 12 can be pushed to rotate for an angle through the matched inclined plane, and meanwhile, the rotating rod 12 pushes the other wedge-shaped sliding block to ascend through the other inclined plane. The rotating rod 12 is fixedly connected with a first-stage input gear of a two-stage speed-increasing gear set 11 and is mounted on the ground 17 together, and the rotating rod and the ground are coaxial and can rotate together but cannot move. And a second-stage output gear of the second-stage speed increasing gear set is fixedly connected with the U-turn turntable 1, is coaxial and can rotate together. Through the secondary speed increasing gear set 11, the rotating rod can drive the U-turn turntable 1 to rotate 180 degrees by rotating through a small angle.

As shown in fig. 6, the two-stage speed increasing gear set is composed of a first-stage input gear 111, a first-stage output gear 112, a second-stage input gear 113, and a second-stage output gear 114. The first-stage input gear 111 is matched with the first-stage output gear 112, and the first-stage input gear 111 rotates to drive the first-stage output gear 112 to rotate. The second stage input gear 113 is matched with the second stage output gear 114, and the second stage input gear 113 rotates to drive the second stage output gear 114 to rotate. The first stage output gear 112 is fixedly connected with the second stage input gear 113 and is mounted on the ground 17, the first stage output gear 112 and the second stage input gear 113 can rotate together and cannot move, and the first stage output gear 112 rotates to drive the second stage input gear 113 to rotate.

Assuming that the depressed pedal (a)5 is on the side far from the inlet of the device and the depressed pedal (b)6 is on the side near the inlet of the device in the initial state, the depressed pedal (a)5 is higher than the u-turn turntable 1, and the depressed pedal (b)6 is level with the turntable 1.

When a first automobile drives in, the first automobile firstly passes through the press-down pedal (b)6, but does not work, after the automobile completely drives on the turntable, the press-down pedal (a)5 is pressed down, the press-down pedal (a)5 descends together with the fixedly connected circular slide rail (a)7, the wedge-shaped slide block (a)9 is pushed to descend, the rotary rod 12 is further pushed to rotate through the inclined surface, and the wedge-shaped slide block (a)9 can only move up and down due to the limitation of the limiting support and cannot rotate. The rotating rod 12 drives the U-turn turntable 1 to rotate through the secondary speed increasing gear set 11, and drives the self-locking rods (a)3 and (b)2 on the side wall of the turntable to slide out of the groove along the side wall of the ground 17 to complete unlocking, and at the moment, the compression springs (a)19 and (b)18 are compressed. In the process, the wedge-shaped sliding block (b)10 at the other end of the rotating rod 12 is pushed by the inclined surface of the rotating rod 12 to ascend, and further pushes the circular sliding rail (b)8 and the pressing pedal (b)6 to ascend.

When the turning turntable 1 pushes the press pedal to rotate with the circular slide rail, the wedge-shaped slide block is sleeved on the circular slide rail and can rotate along the circular slide rail, so that the turning turntable cannot be clamped.

When arbitrary pushing down the footboard and not atress, compression spring and gag lever post can not the roll-off recess, only when the car pushes down a certain pushing down footboard, when promoting the carousel 1 that turns around and rotate, compression spring and gag lever post just can the roll-off recess.

After the U-turn is finished, the positions of the press pedal (a)5 and the press pedal (b)6 are exchanged, the press pedal (b)6 is higher than the U-turn turntable, and the press pedal (a)5 is level with the U-turn turntable 1. The self-locking rods (a)3 and (b)2 on the side wall of the turntable slide into the other side chute corresponding to the original chute on the side wall of the ground 17 under the action of the compression springs (a)19 and (b)18 to complete self-locking.

When a second vehicle enters, the pressing pedal (b)6 is pressed down, the device moves reversely to the device when the pressing pedal (a)5 is pressed down, and the U-turn turntable 1 rotates reversely. And after the second vehicle finishes turning around, the device returns to the initial state. The above operation is repeated when the vehicle enters again.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
