Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an energy-absorbing structure for a rear-end collision seat in a form of crushing, so as to solve the problem of the energy-absorbing structure used for rear-end collision buffering on the recliner connection plate in the prior art due to adjustment. The force of the connecting plate of the corner joint 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

[0043] Such as image 3 only Figure 13As shown, the present invention discloses an energy-absorbing structure for a rear-end collision seat, including a seat cushion side plate 3 and a recliner connecting plate 4, the front end of the recliner connecting plate 4 and the rear portion of the seat cushion side plate 3 The upper end is connected to form a first connection structure 5, and the rear end of the recliner connecting plate 4 is connected to the rear lower end of the seat cushion side plate 3 to form a second connection structure 6, wherein the first connection structure 5 is a bolt connection structure;

[0044] The second connection structure 6 is an energy-absorbing connection structure composed of an energy-absorbing plate 7 , an upper-end bolt connection structure 8 and a lower-end bolt connection structure 9 , and the upper end of the energy-absorbing plate 7 is connected through the upper-end bolt connection structure 8 The rear end of the recliner connecting p...

Embodiment approach

[0052] Such as Image 6 , Figure 8 with Figure 9 As shown, the energy absorbing plate 7 is composed of an upper plate part 7-1, a single-sided middle plate part 7-2 and a lower plate part 7-3 connected in sequence, and the upper plate part 7-1 and the lower plate part The plate portions 7-3 are coplanar, and the single-sided middle plate portion 7-2 protrudes toward the cushion side plate 3, that is, the left or right direction of the car seat, to form the concave-convex structure 7a; , the upper end and the lower end of the energy-absorbing plate 7 are respectively located on the upper plate portion 7-1 and the lower plate portion 7-3.

[0053] The above is the basic implementation mode of the second embodiment, further optimization, improvement and limitation can be done on the basis of the basic implementation mode:

[0054] Preferably: the cross-sectional shape of the single-sided middle plate portion 7-2 is arc-shaped (see Image 6 ), rectangular half (see Figure ...

Embodiment 3

[0056] On the basis of the above-mentioned embodiment 1, the present embodiment 3 also adopts the following preferred implementation modes:

[0057] Such as Figure 10 , Figure 11 with Figure 12 As shown, the energy-absorbing plate 7 is composed of an upper plate part 7-1, a double-sided middle plate part 7-4 and a lower plate part 7-3 connected in sequence, and the upper plate part 7-1 and the lower plate part The plate parts 7-3 are in the same plane, and the double-sided middle plate part 7-4 is composed of a connected upper end middle plate part 7-4-1 and a lower end middle plate part 7-4-2, and the upper end middle plate part 7 -4-1 is connected with the upper plate part 7-1, the lower middle plate part 7-4-2 is connected with the lower plate part 7-3, the upper middle plate part 7-4-1 and the lower end One of the middle plate parts 7-4-2 protrudes toward the left side of the cushion side plate 3, that is, the car seat, and the other protrudes toward the right side o...

Abstract

The invention discloses a crushing deformation type rear-end crash seat energy-absorbing structure. An energy-absorbing connecting structure consisting of an energy-absorbing plate, an upper end boltconnecting structure and a lower end bolt connecting structure is taken as a second connecting structure so as to connect the rear end part of an angle adjuster connecting plate and the rear part of acushion side plate, so that, when a rear-end crash occurs for a vehicle using the structure, the impact force of a passenger on a seat backrest can be transferred to the cushion side plate through the upper end bolt connecting structure, the energy-absorbing plate and the lower end bolt connecting structure in sequence by the angle adjuster connecting plate. A concave-convex structure is arrangedon the energy-absorbing plate that a two-force rod structure is formed by the connecting structure, buffering energy absorption of impact force on the automobile seat backrest in the rear-end crash process of a passenger can be realized, and the structure has the advantages that the cushioning energy-absorbing process is extremely stable, the design and optimization difficulty is low, the cushioning energy-absorbing effect is extremely high, the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to an energy-absorbing structure of a rear-end collision seat in a crushing form, which belongs to the technical field of automobile seats. 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 connection plate 4, the front end of the recliner connection plate 4 is connected with the rear upper end of the cushion side plate 3 to form a first connection structure 5, the rear of the recliner connection plate 4 The end is connected with the rear lower 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]...
