Embodiment 1
[0054] Such as Figure 1 to Figure 5 As shown, the present invention discloses a car seat support structure with collision energy absorption characteristics, including a seat cushion 1, a height adjustment device and a mounting base 2, and the height adjustment device is provided with a height adjustment drive assembly and two sets of connection rod assembly;
[0055] The two groups of connecting rod assemblies are respectively located on the left side and the right side and are respectively installed between the cushion side panel 1-1 on the left side of the cushion 1 and the installation base 2 and on the cushion side on the right side of the cushion 1 Between the plate 1-1 and the installation base 2, two sets of planar four-bar linkage mechanisms are formed, that is, the linkage assembly includes a front link 3, a front bracket 4, a rear link 5 and a rear bracket 6 , the front bracket 4 and the rear bracket 6 are all fixedly installed on the installation base 2, and the u...
Embodiment 2
[0062] On the basis of the first embodiment above, the second embodiment also adopts the following preferred structure:
[0063] The structural strength of each buffer strip 7-2 of the grid energy-absorbing structure 7 increases along the V direction one by one.
[0064] Therefore, when a car collides with the rear, through the design that the structural strength of each buffer bar 7-2 is gradually enhanced along the V direction, the first buffer bar 7-2 can be placed on the rear link. 5 rapidly undergoes plastic deformation under the impact force, and guides the rear link 5 to press figure 1 Continue to rotate in the counterclockwise direction, so as to make contact with other buffer bars 7-2 one by one according to the V direction; and, due to the higher structural strength of the buffer bars 7-2 at the end of the V direction, it can ensure that the grid The grid energy-absorbing structure 7 will not fall off during a rear-end collision, and limits the rotation angle of the...
Embodiment 3
[0066] On the basis of the above-mentioned embodiment two, the present embodiment three also adopts the following preferred structure:
[0067] The rear bracket 6 is provided with a rear bracket mounting plate 6-1, and the lower end of the rear connecting rod 5 is hinged on the rear bracket mounting plate 6-1; the buffer bar 7-2 is composed of a straight section and a connecting section The connection structure, and the straight line section is fixedly connected to the connecting block 7-1, the connecting section is fixedly connected to the rear bracket mounting plate 6-1, and the straight line section is parallel to the rear connecting rod 5 and the rear The hinge axis of the bracket mounting plate 6-1, the straight section of each buffer bar 7-2 is located on the rotation plane of the rear link 5 of the other set of the link assembly, and the V direction is A straight line direction from the upper front to the lower rear; so that: when the rear connecting rod 5 rotates in th...
