Abstract
The utility model belongs to the technical field of automobile safe driving, and particularly relates to a diving-preventing connection rod structure of an automobile seat. The diving-preventing connection rod structure comprises a first connection rod fixedly arranged on the automobile seat and a third connection rod fixedly arranged on an automobile floor. A second connection rod is arranged between the first connection rod and the third connection rod, one end of the second connection rod is hinged with the first connection rod, and the other end of the second connection rod is hinged with the third connection rod. A reset spring is further connected under the automobile seat, and the reset spring is connected with the second connection rod. The diving-preventing connection rod structure has the advantages of preventing the seat from diving, and meanwhile enabling the seat to have upward motion component on the condition that the seat moves forward slightly, and achieving the purpose of preventing a dummy from moving forwards.
Description
Technical field
The utility model belongs to the vehicle safety travel technical field, especially relates to a kind of anti-dive bar linkage structure of automotive seat.
Background technology
In vehicle impact testing, the design point of seat and locating information are most important concerning the collision safety of front.At present along with automobile pollution constantly rises; traffic accident takes place also more and more frequent; the generation of some of them accident is exactly because existing seat lacks anti-dive protection mechanism; when vehicle is collided; seat has dive trend; the occupant is subjected to force of inertia effect health can continue to travel forward simultaneously; head and neck are inflicted heavy losses on easily; the harm personal safety; as notification number be: a kind of automotive seat that the Chinese utility model of CN202106877U provides, comprise cushion and backrest, it also comprises a U-shaped fender bracket and two locating pieces; two ends and the backrest of described U-shaped fender bracket are hinged, and every locating piece is located at U-shaped fender bracket one side-lower and is fixed on the backrest.
The utility model content
The utility model mainly is to cause personal injury easily at existing general-utility car seat is existing; there is the problem of hidden danger in safe driving; provide a kind of and can effectively reduce occupant's trend that travels forward, the anti-dive bar linkage structure of the automotive seat of protection occupant personal safety.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of anti-dive bar linkage structure of automotive seat, it comprises and is installed in the first connecting rod on the automotive seat and is installed in third connecting rod on the automotive floor panel, be provided with second connecting rod between first connecting rod and the third connecting rod, one end and the first connecting rod of second connecting rod are hinged, the other end and the third connecting rod of second connecting rod are hinged, the automotive seat below also is connected with retracing spring, and retracing spring is connected with second connecting rod.Behind auto against; automotive seat have dive and reach trend; second connecting rod can withstand seat; stop the dive of seat; first connecting rod moves forward with seat simultaneously; second connecting rod is swung certain angle thereupon; second connecting rod can form thrust upwards to seat in the vertical direction; seat is lifted certain height; the proal displacement of occupant and speed have been slowed down so to a certain extent; increased the frictional area of member and chair surface, protected the occupant, reached and reduce the travel forward purpose of trend of occupant.
As preferably, described second connecting rod is hinged by bolt and first connecting rod, and second connecting rod is hinged by bolt and third connecting rod.By bolted splice, simple in structure, technology maturation and cost are low.
As preferably, described retracing spring is extension spring, and an end and the automotive seat of retracing spring are fixed, and the other end is articulated on the bolt cap of first connecting rod and second connecting rod hinged place.After collision finished, retracing spring can spur second connecting rod to initial position.
As preferably, the pivot angle scope of described second connecting rod is 75 °～100 °.The pivot angle scope of second connecting rod is 75 °～100 °, and hunting range is reasonable, the connecting rod stuck phenomenon can not occur.
As preferably, described first connecting rod is 0.2～0.4 times of second connecting rod length.For making the second connecting rod flexible swinging, the length of first connecting rod should be shorter, and it is 0.2～0.4 times of second connecting rod length, satisfies operating needs.
As preferably, the bar linkage structure of being made up of first connecting rod, second connecting rod and third connecting rod has two, and two bar linkage structures are symmetricly set on the leading portion of automotive seat below.Two bar linkage structures are arranged in the automotive seat below symmetrically and evenly, and behind auto against, two bar linkage structures act on simultaneously, stress equalization, Stability Analysis of Structures.
Therefore, the beneficial effects of the utility model are: anti-dive bar linkage structure is set below automotive seat, not only can prevents the seat dive, can also take place under the situation of a small amount of reach at seat simultaneously, make seat have the upward movement component, play the purpose that prevents dummy's movement tendency forward.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Shown in the figure: 1-first connecting rod, 2-second connecting rod, 3-third connecting rod, 4-automotive seat, 5-retracing spring.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
Shown in Figure of description 1, a kind of anti-dive bar linkage structure of automotive seat, it comprises the first connecting rod 1 that is installed on the automotive seat 4, with the third connecting rod 3 that is installed on the automotive floor panel, be provided with second connecting rod 2 between first connecting rod 1 and the third connecting rod 3, one end of second connecting rod 2 is hinged by bolt and first connecting rod 1, the other end of second connecting rod 2 is hinged by bolt and third connecting rod 3, first connecting rod 1 is 0.3 times of second connecting rod 2 length, automotive seat 4 belows also are connected with retracing spring 5, retracing spring 5 is extension spring, one end of retracing spring 5 and automotive seat 4 are fixing, the other end is articulated on the bolt cap of first connecting rod 1 and second connecting rod 2 hinged places, by first connecting rod 1, the bar linkage structure that second connecting rod 2 and third connecting rod 3 are formed has two, and two bar linkage structures are symmetricly set on the leading portion of automotive seat 4 belows.
