Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an energy-absorbing structure of a stretched rear-end collision seat to solve the problem that the energy-absorbing structure used for rear-end collision buffering is provided on the recliner connecting plate in the prior art. The force of the connecting plate of the device is relatively complicated and the force is very unstable, so there is a problem that the design of the energy-absorbing structure is difficult and the energy-absorbing effect is poor

Embodiment 1

[0038] Such as Figure 3 to Figure 9 As shown, the present invention discloses an energy-absorbing structure for a stretched rear-end collision seat, which includes a seat cushion side panel 3 and a recliner connecting plate 4, and the front part of the lower end of the recliner connecting plate 4 is connected to the seat cushion side panel 3 is connected to form a first connection structure 5, and the rear end of the lower end of the recliner connecting plate 4 is connected to the rear end of the seat cushion side panel 3 to form a second connection structure 6, wherein the second connection structure 6 is a bolt connection structure, the upper end of the recliner connecting plate 4 is connected to the recliner 2;

[0039]The first connection structure 5 is an energy-absorbing connection structure composed of an energy-absorbing member 7, an upper-end bolt connection structure 8 and a lower-end bolt connection structure 9. The arc-shaped chute 3a on the axis of the two conne...

Embodiment 2

[0046] Such as Figure 3 to Figure 8 As shown, on the basis of the first embodiment above, the second embodiment also adopts the following preferred implementation modes:

[0047] The energy-absorbing member 7 is a metal sheet, and when the tensile force received by the energy-absorbing member 7 is within the preset force range of the normal driving of the automobile, the energy-absorbing member 7 is in the elastic deformation stage before yielding , when the tensile force received by the energy-absorbing member 7 is within the preset stress range of a rear-end collision of a car, the energy-absorbing member 7 is in a plastic deformation stage after yielding.

[0048] Therefore, when the car does not collide with the rear and the occupants use the car seat normally, the energy absorbing member 7 is subjected to a relatively small stretching force in the normal driving force range of the car, and the energy absorbing member 7 only produces a small amount of tension. The elasti...

Embodiment approach

[0056] The energy-absorbing member 7 is a nonlinear elastic element, and the spring stiffness of the nonlinear elastic element when the tensile force received by the energy-absorbing member 7 is in the preset stress range of the car during normal driving is greater than that of the nonlinear elastic element The spring rate when the tensile force received by the energy-absorbing member 7 is within the preset stress range of a car rear-end collision.

[0057] Therefore, when the car does not collide with the rear and the occupant uses the car seat normally, the energy-absorbing member 7 is subjected to a small tensile force in the normal driving force range of the car, and the energy-absorbing member 7 with a larger spring rigidity Part 7 only produces slight elastic deformation to ensure the normal use of the car seat; and when the vehicle collides rear-end, the energy-absorbing part 7 is subjected to a larger tensile force in the force range of the rear-end collision of the car...

Abstract

The invention discloses a stretching type rear-end collision seat energy absorption structure, which comprises a seat cushion side plate and an angle adjuster connecting plate. The front portion of the lower end of the angle adjuster connecting plate is connected with the rear end of the seat cushion side plate to form a first connecting structure, the rear portion of the lower end of the angle adjuster connecting plate is connected with the rear end of the seat cushion side plate to form a second connecting structure, and the second connecting structure is a bolt connecting structure. The first connecting structure is an energy absorption connecting structure composed of an energy absorption part, an upper end bolt connecting structure and a lower end bolt connecting structure. When a rear-end collision occurs in a vehicle adopting the device, the vehicle cannot be collided; passengers have very large impact force on the seat backrest; the energy can be transmitted to the cushion sideplate by the angle adjuster connecting plate through the upper end bolt connecting structure, the energy absorbing part and the lower end bolt connecting structure in sequence; therefore, in the impact process of automobile rear-end collision, the upper end of the energy absorption part and the upper end bolt connecting structure slide backwards along the arc-shaped sliding groove together, the energy absorption part is stretched and deformed in the process, and buffering and energy absorption are achieved.

Description

technical field [0001] The invention relates to a car seat, in particular to an energy-absorbing structure of a stretched rear-end collision seat. Background technique [0002] Such as figure 1 As shown, the existing car seat uses two recliners 2 to connect the backrest frame 1 and the cushion side panels 3 located on the left and right sides of the seat cushion frame, wherein the connection method between the recliner 2 and the seat cushion side panels 3 It is: the recliner 2 has a recliner connecting plate 4, the lower front part of the recliner connecting plate 4 is connected with the rear end of the seat cushion side plate 3 to form a first connection structure 5, the reclining connecting plate 4 The rear part of the lower end is connected with the rear end of the cushion side panel 3 to form a second connection structure 6, and both the first connection structure 5 and the second connection structure 6 are bolt connection structures. [0003] Such as figure 1 with ...
