Embodiment 1

[0038] see Figure 1~4 The energy-absorbing support leg of the child car seat shown, the support leg includes a leg body 1 extending in the up and down direction, the leg body 1 is telescopically arranged in the up and down direction, and the leg body 1 is provided with a height adjustment The locking mechanism makes the leg body 1 have different heights. see Figure 1~4 As shown, the leg body 1 includes an outer rod 11, an inner rod 12 slidably inserted in the outer rod 11 in the up and down direction, and the locking mechanism includes a plurality of position-limiting holes 16 spaced along the height direction of the outer rod 11. The rotating shaft 15 is rotatably disposed on the locking rod 13 in the inner rod 12 , wherein the axis of the rotating shaft 15 extends along the radial direction of the inner rod 12 . The upper end of the locking rod 13 has a hook portion 14 protruding out of the inner rod 12 along the radial direction of the inner rod 12 , and the hook por...

Embodiment 2

[0044] see Figure 5-8 The difference between the energy-absorbing supporting legs of the child car seat shown in Embodiment 1 is that in this embodiment, the telescopic cylinder 3 as an energy-absorbing device is arranged on the upper part of the supporting leg body 1 .

[0045] See attached Figure 5-8 As shown, the upper part of the leg body 1 is provided with an upper shell 5, and the upper shell 5 is connected with a child car seat (not shown in the figure). The outer rod 11 of the leg body 1 can be slidably inserted up and down in the inner cavity of the upper housing 5, and the cylinder body 32 of the telescopic cylinder 3 is supported on the upper end of the outer rod 11 and fixedly connected with it. Under normal circumstances, the huge impact on the child car seat will act on the telescopic cylinder 3 through the upper shell 5, and the axial force received by the telescopic cylinder 3 will make the telescopic rod 31 shrink relative to the cylinder body 32, there...

Embodiment 3

[0048] See attached Figure 9 to attach Figure 13 The energy-absorbing support leg of the child car seat shown, the support leg includes a leg body 1 extending in the up and down direction, the leg body 1 includes an outer rod 11, and an inner rod 11 that is slidable in the up and down direction. The rod 12 and the strut 17 are slidably provided in the inner rod 12 in the up and down direction. The inner rod 12 has a plurality of optional positions relative to the outer rod 11, and the height between the two is adjusted by a locking mechanism. Here, the locking part 18 with the locking column 19 is used to cooperate with the limiting hole 16 to realize the two. locking. An unlocking button 4 is provided on the outer rod 11 for unlocking the above-mentioned locking mechanism.

[0049] In this embodiment, the telescopic cylinder 3 is arranged in the inner rod 12 and between the inner rod 12 and the support rod 17 , that is, the telescopic cylinder 3 is arranged at the u...

Abstract

The invention discloses an energy absorption supporting leg of a child vehicle seat. A telescopic cylinder is arranged on a supporting leg body, or the telescopic cylinder is directly used as the supporting leg. When vehicle collision happens suddenly or other emergencies happen, large impact on the child vehicle seat is exerted on the telescopic cylinder, so that a telescopic rod of the telescopic cylinder contracts relative to a cylinder body and moves, accordingly, child vehicle seat buffering force is provided, energy generated due to collision is absorbed, the trend that the child vehicle seat rushes forwards is buffered, the damping effect on the child vehicle seat is achieved, and damage to a child who sits on the child vehicle seat is lowered or avoided.

Description

[0001] Technical field [0002] The present invention involves an energy -absorbing leg of a children's vehicle seat. Background technique [0003] In existing technologies, children's car seats usually include a base body for connected to the car seat and a fixed child seat set on the base body.In order to prevent the front leaning or backward of the child's seat, the legs with supporting the base body are usually set up in the front and lower part of the base body.However, under the sudden collision or other emergencies, the children's car still has a great impact, which may cause harm to the children sitting on it. Invention content [0004] The purpose of the present invention is to provide an energy -absorbing support leg for children's vehicle seats, so as to absorb energy absorption of children's vehicle seats, reduce or avoid children's injury. [0005] In order to achieve the above -mentioned purpose, the technical solution adopted by the present invention is: an energy...
