Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
The anti-bending structure 1 of the automobile seat cushion side plate comprises a cushion side plate 2, a rear connecting rod support 3 and a buffer piece 4, wherein the rear connecting rod support 3 is fixedly installed at the lower end of the cushion side plate 2, the buffer piece 4 is used for connecting the rear connecting rod support 3 with the cushion side plate 2, a plurality of round holes are formed in the buffer piece 4 at intervals along the buffer piece 4 and communicated to form a long hole 41, the width of the joint between every two adjacent round holes is smaller than the diameter of the round hole, the rear connecting rod support 3 is provided with a round shaft 31 matched with the round hole, one end of the buffer piece 4 is hinged to the cushion side plate 2, and the other end of the buffer piece is embedded. This scheme simple structure, under the prerequisite that does not influence seat altitude mixture control function, when the car bumps especially when knocking into the back the collision, absorb the impact energy who transmits to seat cushion curb plate 2 through taking place tensile and compressive deformation, prevent that too big perk from bending deformation to appear in seat cushion curb plate 2, buffering passenger is to the impact force of seat cushion, alleviate the impact damage of passenger under the speed of taking place different collisions, prevent simultaneously to a certain extent that the cushion skeleton suddenly sinks fast in knocking into the back the collision, effectively improve car seat's security. In addition, this car seat cushion 2 structure of preventing bending has manufacturability and the assembly nature that easily realizes, and is with low costs, and the practicality is strong. In order to avoid interference between the cushion 4 and other components (such as a seat belt buckle), the position of the cushion 4 needs to be reasonably arranged, and the cushion 4 is arranged on the outer side of the seat cushion side plate 2 in the embodiment.
The buffer member 4 in this embodiment is as shown in fig. 6, a plurality of round holes are arranged along the buffer member 4 at intervals, the round holes are uniform in size, the distance between the centers of the round holes between two adjacent round holes is greater than the diameter of the round hole, the round holes are communicated to form a strip hole 41, the joint between the adjacent round holes is a small arc bent inwards (the small arc can be a straight line or a small arc bent outwards, and only the width between the two sides needs to be smaller than the diameter of the round hole), the distance between the arc-shaped sides at the two sides is smaller than the diameter of the round hole, so that the round shaft 31 can be clamped at the joint in any round hole when the round shaft 31 is nested, and the round shaft 31 cannot easily slide into other round holes.
When the automobile has rear-end collision, under the action of great impact force, the cushion side plate 2 without the side of the height adjuster sinks more seriously at two ends because the rigidity strength is relatively lower, and the oblique downward impact force transmitted to the rear end of the cushion side plate 2 is larger than that at the front end, so that the cushion side plate 2 is easily bent and deformed greatly inwards or outwards in the area near the rear connecting rod support 3, but no matter the cushion side plate 2 generates serious plastic deformation outwards or inwards, the common cushion side plate 2 has the bending trend and the deformation phenomenon of upwards tilting, namely, the distance between the upwards bending area of the cushion side plate 2 and the circular shaft 31 of the rear connecting rod support 3 is continuously increased. In this embodiment, two ends of the buffer member 4 are fixedly connected to the cushion side plate 2 and the rear link bracket 3 by bolts 5, so that the circular shaft 31 can be prevented from laterally separating from the circular hole. At this moment, under the impact at the moment of rear-end collision, the round shaft 31 of the rear connecting rod bracket 3 makes downward impact motion relative to the long hole 41 of the buffer plate, so that the round shaft 31 rapidly presses the arc-shaped sides at the two sides of the long hole 41 below the round shaft, the round shaft 31 slides to the next round hole, the arc-shaped sides are elastically deformed to clamp and buffer the round shaft in the sliding process, and the impact force transmitted to the side cushion side plate 2 in the rear-end collision is effectively reduced. The small arc and the round hole are in smooth transition, so that the round shaft 31 can smoothly slide to the next round hole, and the impact force cannot be slowed down due to too large resistance and too small elastic deformation of the arc-shaped side edge.
Preferably, through grooves 43 for providing elastic deformation spaces are further formed on two sides of the small arc of the buffer 4 corresponding to the joint between two adjacent round holes. The through groove 43 in this embodiment is an arc groove fitted with a small arc, and when receiving an impact force, the circular shaft 31 moves downward along the strip hole 41, and when punching two arc-shaped sides, the two arc-shaped sides are stressed to elastically deform and extrude the arc groove, so that the impact force of the circular shaft 31 is reduced.
The shape, size and arrangement of the long holes 41 not only need to ensure that partial energy can be absorbed through compression deformation at a small arc necking under the action of great impact force in rear-end collision, and the bending of the cushion side plate 2 is reduced, but also the height adjustment of the cushion framework is not affected. When the automobile seat is in a static state, the round shaft 31 of the rear connecting rod bracket 3 is positioned in one of the long holes 41 of the buffer member 4; when the height of the seat cushion of the automobile seat needs to be adjusted, the rear link bracket 3 and the slide rail mechanism fixed on the automobile body are kept stationary through a welding connection mode, the seat cushion side plate 2 generates height change along with the link mechanism under the action of the height adjuster, the round shaft 31 of the rear link bracket 3 moves relatively in the long hole 41 along with the height change of the seat cushion side plate 2, for example, if the seat cushion side plate 2 moves downwards through the height adjuster, the buffer member 4 also moves downwards, and the round shaft 31 of the rear link bracket 3 moves upwards along the long hole 41 relative to the buffer member 4. The length of the slot 41 is required to ensure that the seat cushion can be adjusted to the highest and lowest positions, depending on the change in the height adjustment stroke and trajectory of different seats. And the round shaft 31 of the rear connecting rod support 3 can make the small arc generate elastic deformation by compressing the arc-shaped groove at the inner side of the small arc, which is more beneficial to the smooth movement of the round shaft 31 of the rear connecting rod support 3 in the long hole 41.
Buffer 4 in this implementation with the one end both sides that cushion curb plate 2 is connected are inwards sunken to form constriction 42, because when the car takes place to collide with the back, under the effect of very big impact force, the interval between the regional and the back connecting rod support 3 of bending upwards of cushion curb plate 2 is constantly increasing, when cushion curb plate 2 atress is buckled, tensile buffer 4, it is less because the width is less than other sections to be close to the one on the constriction 42 of cushion curb plate 2 connection this moment, here takes place tensile plastic deformation at first and absorbs impact energy, slow down the impact force that car seat received. Through foretell two kinds of deformation mode effective absorption to this side cushion curb plate 2 impact energy who transmits in the collision of knocking into the back, prevent that the bending deformation of its perk is too big, still prevent to a certain extent that the cushion skeleton from sinking fast suddenly, improve car seat's security.
According to different seats, the cushion 4 in the scheme can be selected from materials with the elongation rate larger than 15 by combining the overall arrangement (such as height adjustment stroke and track) of the seat framework of the seat and the structural form (such as rigidity distribution) of the cushion side plate 2, and the optimal design of the thickness and the material of the cushion 4, the size and the shape of the contraction opening 42, the length and the arrangement of the strip hole 41, the number and the size of the inner circular holes of the strip hole 41, the size and the distance between two sides of the small circular arc in the strip hole 41 and the shape size and the arrangement of the through groove 43 is carried out through material test piece tensile test and finite element virtual simulation analysis. The realization chooses for use more suitable structure of preventing buckling to different seats.
The rear connecting bracket in this embodiment is a triangular connecting piece, the circular shaft 31 is arranged at one corner of the triangular connecting piece, and one side opposite to the circular shaft 31 is fixed on the lower sliding rail of the automobile. The other side of the rear connecting support, which is opposite to the side connected with the buffer part 4, is provided with a through hole 32 used for being connected with a connecting rod mechanism, and the connecting rod mechanism in the automobile seat framework is hinged to the through hole 32. Wherein the circle axle 31 cover is equipped with the plastics external member that is used for reducing the removal noise, and wherein the plastics external member can adopt other materials that can the noise reduction to make, can reduce the noise that the circular axle 31 atress extrudees the arc side and produce at the in-process that the round hole removed through this plastics external member.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
