Detailed Description
The utility model provides a car seat anti-diving device, includes that the pole length direction that is located the anterior below of seat cushion is unanimous with car width direction's anti-diving horizontal pole 10, its characterized in that: the anti-diving cross rod 10 is connected with a reset mechanism for driving the anti-diving cross rod to reset from a low position to a high position, the high position limiting mechanism and the low position limiting mechanism limit the anti-diving cross rod 10 at the high position and the low position respectively, and an unlocking driving force for releasing the low position limitation during collision is arranged on the high position limiting mechanism and the low position limiting mechanism.
In the scheme, the anti-diving cross bar 10 is placed at a low position after the automobile leaves a factory, the anti-diving cross bar is limited by the limiting mechanism, a driver cannot easily feel the limiting mechanism at the low position when the driver normally runs, the anti-diving cross bar 10 cannot easily press legs of the driver to improve the riding comfort of the driver, the safety threat of the driver is small due to the fact that slight collision is low to the diving effect of the driver, the anti-diving cross bar 10 is set to be released from the low position limit and rapidly reaches the high position when the automobile collides and the collision force of the automobile exceeds a threshold value, the pelvis forward movement of the driver is prevented to guarantee the personal safety of the driver, and the anti-diving cross bar 10 is placed at the low position again after the automobile collides.
The resetting mechanism comprises two swing rods 30, the rod length direction of each swing rod 30 is perpendicular to the rod length direction of the corresponding anti-submergence cross rod 10, the upper ends of the swing rods 30 are connected with the anti-submergence cross rods 10, the lower ends of the swing rods are hinged to the lower seat framework 1, and the direction of a hinge shaft 31 of each swing rod is consistent with the width direction of the vehicle. The lifting of the anti-diving cross bar 10 is realized by the resetting mechanism through the back-and-forth swinging of the resetting mechanism, and the structure is simple and easy to realize.
The reset mechanism comprises a reset spring 20, and the reset spring 20 is a compression spring or a torsion spring on a hinge shaft 31 which is positioned between the swing rod 30 and the lower seat framework 1. The reset spring 20 is a compression spring or a torsion spring with strong elastic force, which is beneficial to improving the reset speed of the anti-diving cross bar 10 and improving the safety.
High, low-order stop gear is including fixed limiting plate 40 that sets up two inboards about the seat skeleton 2, limiting plate 40's face is located the plummet and car length direction place plane, the relative dysmorphism groove 41 of notch has been seted up to two limiting plate 40 inboards, dysmorphism groove 41 comprises rectangular channel 411 and the half slot 412 that is located rectangular channel 411 rear portion below, the rod end of preventing latent horizontal pole 10 is located the dysmorphism groove 41 of both sides limiting plate 40, it is spacing to constitute the high position of preventing latent horizontal pole 10 when the rod end of preventing latent horizontal pole 10 contacts with the preceding cell wall of rectangular channel 411, it is spacing to constitute the low position of preventing latent horizontal pole 10 with its cell wall when the tubulose anti-latent horizontal pole 10 is located half slot 412. The force applied to the anti-diving cross bar 10 at the high position during collision is mainly the reset force of the reset mechanism and the thrust of the human pelvis at the rear part of the anti-diving cross bar 10, and the front groove wall of the rectangular groove 411 in front of the rod end of the anti-diving cross bar 10 effectively blocks the forces, so that the anti-diving cross bar 10 is stably at the high position, the reset force of the reset mechanism enables the anti-diving cross bar 10 to have a forward swinging trend when the anti-diving cross bar 10 is at the low position, and the front groove wall of the semicircular groove 412 interferes with the anti-diving cross bar 10 to block the reset trend of the anti-diving cross bar 10.
The unlocking driving force is the inertia force of the anti-diving cross bar 10 during the collision of the automobile. When the vehicle collides, the anti-diving cross bar 10 has a forward inertial force, and the inertial force drives the anti-diving cross bar 10 to swing forward and extrude the interference area between the front wall of the semi-circular groove 412 and the anti-diving cross bar 10, so that the interference area is elastically deformed to achieve the purpose of unlocking the low position limit
The front groove wall of the semi-circular groove 412 and the lower groove wall of the rectangular groove 411 are transited by an arc-shaped groove wall, and the curvature axis of the arc-shaped groove wall is located in the vehicle width direction. Therefore, the horizontal inertia force of the anti-diving cross rod 10 acts on the arc-shaped groove wall and is changed into a force along the arc tangential direction, so that the deformation of an interference area is more facilitated, the interference amount is reduced, the unlocking of the inertia force is facilitated, and the elastic deformation capacity of the arc-shaped groove wall and/or the rod end of the anti-diving cross rod 10 can be increased by coating elastic smooth materials on the arc-shaped groove wall and/or the rod end to achieve the purpose of facilitating the unlocking of.
The shortest distance L1 between the axis core of the articulated shaft 31 and the pipe wall of the anti-diving cross bar 10 is smaller than the longest distance L2 between the axis core of the articulated shaft 31 and the inner wall of the arc-shaped groove wall, the distance difference between the axis core of the articulated shaft 31 and the inner wall of the arc-shaped groove wall is delta L, and delta L is more than or equal to 0.5mm and less than or equal to 2 mm. The Δ L in the above scheme is the interference between the anti-diving cross bar 10 and the arc-shaped groove wall, and the interference needs to ensure that the anti-diving cross bar 10 cannot be reset during normal driving, and can be quickly deformed and reset under stress when the vehicle is in strong collision. If the arc-shaped groove wall and/or the rod end of the anti-dive crossbar 10 is coated with an elastic smooth material, the interference amount Δ L is appropriately increased.
The front part of the limiting plate 40 is fixedly connected with the left inner side and the right inner side of the seat framework 2, and the rear part of the limiting plate 40 is suspended. Therefore, the elastic deformation capacity of the limiting plate 40 of the suspension part is stronger, and the deformation unlocking of the interference area is more facilitated during collision.
The lower height of the anti-diving cross bar 10 is higher than the lowest end of the pelvis of the human body on the cushion. In a collision, because the seat cushion is soft and the collision force is large, the inertia force can make the pelvis of a driver move forwards approximately horizontally and press the front cushion instead of moving forwards and upwards along the cushion surface direction, and even if the anti-diving cross bar 10 does not release the low position limit and rises to the high position, a forward force can be applied to the anti-diving cross bar 10 when the human pelvis slides forwards, so that the anti-diving cross bar 10 is positioned before the human pelvis further slides.
