Description
Technical Field
The utility model relates to a car seat spare part technical field, concretely relates to connecting plate under seat angle modulation ware.
Background
As shown in figure 1, the lower connecting plate of the automobile seat angle adjuster is formed by stamping a sheet metal part, a front mounting hole 1 and a rear mounting hole 2 are formed in the lower connecting plate of the angle adjuster and used for being connected with a seat frame side plate, and the front mounting hole 1 and the rear mounting hole 2 are round holes. Fig. 2 is a schematic view showing the installation of the lower connecting plate of the automobile seat angle adjuster on the seat.
During the running process of the automobile, once a front collision occurs, front drivers and passengers are easily injured by the inertia effect of the trunk, and the front driver and the passengers are also called as front trunk dynamic collision. Two mounting holes of the lower connecting plate and the seat frame side plate of the traditional angle adjuster are round holes, so that the lower connecting plate and the seat frame side plate cannot play a role in collision energy absorption in a dynamic collision accident, and drivers and passengers are easily injured. In order to reduce the damage caused by the front collision of the automobile, automobile manufacturers have developed a seat capable of absorbing energy dynamically, for example, an energy absorbing plate is added on the lower connecting plate of the recliner, or various weakening holes and buffer structures are added on the lower connecting plate of the recliner.
For the design that the energy absorption plate is additionally arranged on the lower connection part of the angle adjuster, the number of parts is increased, and the energy absorption plate needs to be installed and fixed, so that the manufacturing and installation are complex; meanwhile, the additionally arranged energy absorption plate easily causes frictional abnormal sound with the lower connecting plate of the angle adjuster in the normal running process. The design that the weakening hole and the buffering structure are additionally arranged on the lower connecting plate of the angle adjuster enables the stamping process of the lower connecting plate of the angle adjuster to be complex, and meanwhile, after the weakening hole and the buffering structure are additionally arranged, the thickness of the lower connecting plate needs to be increased to ensure the overall strength, so that the weight is correspondingly increased, and the lightweight design of products is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a connecting plate under seat angle modulation ware can dynamic energy-absorbing in the car front collision in-process, causes the injury to driver and crew in the collision before reducing, simplifies the structure simultaneously and makes the assembly.
Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a dynamic seat angle modulation ware lower connecting plate of inhaling ability, adopts the sheet metal component punching press to form, is provided with preceding mounting hole and back mounting hole on the connecting plate under the angle modulation ware and is used for linking to each other with the seat frame curb plate, preceding mounting hole is waist shape hole, and the back mounting hole is including installation round hole and arc hole, and installation round hole and arc hole pass through shrink neck intercommunication, and the line of setting for preceding mounting hole and back mounting hole is the X line, and the center of installation round hole and perpendicular to X line are crossed to the Y line, then the extending direction and the X line collineation of preceding mounting hole, and installation round hole and arc hole set up with one heart, and arc hole and shrink neck are in the top of X line and the bilateral symmetry setting at the Y line.
Preferably, the width of the arc-shaped hole is larger than the diameter of the mounting round hole, and the ratio of the width of the necking neck to the diameter of the mounting round hole is 0.4-0.5. The ratio of the width of the contraction neck to the diameter of the bolt through hole is very important for the energy absorption effect, and the ratio is limited to 0.4-0.5 by optimizing the size, so that the best energy absorption effect can be achieved.
More preferably, the radius of the semi-circles at the two ends of the front mounting hole is equal to that of the mounting circular hole, the length of the middle parallel section of the front mounting hole is 1.5-2.5 mm, and the arc angle of the arc-shaped hole is 85-95 degrees. Two bolts with uniform specifications can be selected for mounting the connection between the seat frame side plate and the lower part of the angle adjuster; and the length of the middle parallel section of the front mounting hole and the arc angle of the arc-shaped hole are limited, so that the energy absorption effect is further improved.
The utility model has the advantages that:
(1) the front mounting hole is designed to be a waist-shaped hole, so that the front mounting hole and the rear mounting hole are not affected by manufacturing errors during mounting, and the seat can generate a movement amount along the X-ray direction to further buffer and absorb energy during collision due to the fact that the extending direction of the waist-shaped hole is collinear with the X-ray in the collision process.
(2) The back mounting hole adopts the design of dysmorphism hole, increases shrink neck and arc hole on the basis of round hole, and seat back skeleton whole can form a clockwise's rotation volume round preceding mounting hole when collision before taking place, and the mounting hole can produce the extrusion with connecting bolt downwards behind the angle modulation ware connecting plate promptly, and back mounting hole lapse, and connecting bolt is just in time crowded receipts necking down or passes the shrink neck and crowd the arc downthehole to it produces the deformation energy-absorbing to make under the angle modulation ware connecting plate. When connecting bolt crossed the receipts necking down, the seat was in the moment that the displacement volume is the biggest, in case get into the arc hole, and speed sharply descends to realize dynamic energy-absorbing, add the arc hole and make the shrink neck can in time produce elastic deformation and carry out furthest's energy-absorbing, reduce the injury to driver and crew in the at utmost.
To sum up, the utility model has the characteristics of simple structure, manufacturing and convenient assembling, can dynamic energy-absorbing at car collision in-process, reduce in the front collision to the dynamic impact cause the injury to driver and crew.
