Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1 to 4, the locking and returning structure of an easy entry seat includes a guide rail 1 fixed on a vehicle body floor, and a slide rail 2 engaged with the guide rail 1, and is characterized in that: the front part of the seat cushion framework side wall plate is rotationally connected with the front part of the slide rail 2, the limiting part is arranged at the front end part of the seat cushion framework side wall plate 3, the limiting component 4 is arranged at the front end part of the slide rail 2, and the unlocking component 5 is connected with the limiting component 4 through a zipper 6; the limiting part at the front end part of the side wall plate 3 of the seat cushion framework corresponds to or is matched with the limiting component 4 at the front end part of the slide rail 2. After the rear part of the seat is lifted up, the limiting part at the front end part of the side wall plate 3 of the seat cushion framework is matched with the limiting component 4 at the front end part of the slide rail 2 for limiting. When a passenger in the rear row needs to enter, the rear part of the seat is lifted upwards and lifted to the limiting part at the front end part of the side wall plate 3 of the seat cushion framework to be matched with the limiting component 4 at the front end part of the slide rail 2 for limiting, and the abdication can be realized; the seat is pushed to the foremost position, and the maximum abdicating can be realized. After the rear passenger enters, the rear seat can be lowered and returned by the unlocking member 5. Convenient for the passengers in the back row to get in and out and convenient for operation.
The unlocking member 5 comprises a shifting fork seat 51 fixedly connected to the guide rail 1, a V-shaped shifting fork 52 with the lower part rotatably connected to the shifting fork seat 51, an eccentric spring 53 with one end connected with the shifting fork seat 51 and the other end connected with the middle part of the V-shaped shifting fork 52, a shifting piece 54 with the middle part rotatably connected with the slide rail 2, and a tension spring 55 with one end connected with the upper part of the shifting piece 54 and the other end connected with the slide rail 2; the lower end of the pick 54 corresponds to the V-shaped shift fork 12. Because the lower part of the V-shaped shifting fork 12 is rotationally connected with the shifting fork seat 51, one end of the eccentric spring 53 is connected with the shifting fork seat 51, and the other end is connected with the middle part of the V-shaped shifting fork 52; three states of the V-shaped shift fork 12, a state in which the mouth portion is inclined forward, a state in which the mouth portion is inclined backward, and a state in which the mouth portion is oriented vertically upward, can be realized by the paddle 54.
The limiting component 4 comprises a locking hook 41 and a torsion spring 42, wherein the middle part of the locking hook 41 is rotatably connected to the front end part of the sliding rail 2 through a rotating shaft, the torsion spring 42 is matched with the rotating shaft, one end of the torsion spring 42 is fixed on the locking hook 41, and the other end of the torsion spring is fixed on the sliding rail 2; one end of the zipper 6 is connected to the upper end of the pick 54, and the other end is connected to the lower portion of the latch hook 41.
The limiting part at the front end part of the side wall plate 3 of the seat cushion framework is a lock pin 31.
The utility model discloses the working process is as follows:
in the initial state, as shown in fig. 1. The lock pin 31 at the front end of the side wall plate 3 of the seat cushion framework is not matched with the lock hook 41 at the front end of the slide rail 2 for limiting, and at the moment, the whole seat can normally move forwards and backwards. In the process of forward movement of the seat, the shifting piece 54 can shift the mouth of the V-shaped shifting fork 12 to be inclined forwards; during the backward movement of the seat, the striking plate 54 will strike the mouth of the V-shaped fork 12 and tilt backward.
When the rear part of the seat is lifted upwards or lifted, the rear part of the side wall plate 3 of the seat cushion framework is lifted upwards or lifted along with the rear part of the seat, the lock pin 31 at the front end part of the side wall plate 3 of the seat cushion framework is firstly contacted with the arc surface at the top of the lock hook 41 at the front end part of the slide rail 2, then the rear part of the seat is continuously lifted upwards or lifted, the upper part of the lock hook 41 is stressed to rotate forwards, the torsion spring 42 is compressed until the lock pin 31 slides into the hook part of the lock hook 41, the lock hook 41 is returned by the torsion spring 42 under the action of restoring force, the lock pin 31 is limited in the lock hook 41. After the rear part of the seat is kept in a lifting state, the seat is pushed forwards to the foremost position, the whole seat reaches the largest avoidance space, and the passengers in the back row can conveniently get in and out; at this time, the V-shaped fork 12 is in a state where the mouth portion is inclined forward.
When the seat is returned, the seat firstly slides backwards, and the shifting piece 54 moves backwards along with the slide rail 2; since the middle part of the shifting piece 54 is rotationally connected with the sliding rail 2, when the shifting piece 54 slides backwards to a certain position, the lower end part of the shifting piece 54 is obstructed by the V-shaped shifting fork 12, so that the upper part of the shifting piece 54 rotates backwards, the zipper 6 is driven to enable the upper part of the locking hook to move forwards for unlocking, and the locking pin 31 is separated from the locking hook 41 at the moment, as shown in fig. 4; the rear of the seat falls back to the initial state shown in fig. 1.
The utility model discloses a spare part is less for current spare part that easily gets into seat structure, and convenient assembling is swift, can play good support limiting displacement behind the lifting of seat rear portion. The rear part of the seat can be lowered and returned only by sliding the seat backwards to a specified position, so that the operation is convenient; and the in-process of sliding backward earlier can remind passenger's foot to avoid dangerous position, return at the assigned position simultaneously, can guarantee passenger's safety, avoid the collision injury.
