Abstract

A side impact safety protection device, a child safety seat, and a base, wherein the side impact safety protection device includes: a side impact protection block, including a casing and a pivot disposed in the casing; a driving member, for driving the side impact protection block to an unfolded position or a folded position; and a traction member, one end of the traction member is pivotally connected to the side impact protection block, and the other end of the traction member is connected to the driving member. The side impact safety protection device according to the application is simple in structure and easy to operate, and can realize automatically opening and automatic folding of the side impact safety protection device, which makes the operation more convenient.

Claims (34)

1 . A side impact safety protection device, comprising:

a side impact protection block, including a casing and a pivot disposed in the casing;

a driving member, for driving the side impact protection block to an unfolded position or a folded position;

a traction member fastener; and

a traction member, wherein one end of the traction member is connected to the pivot of the side impact protection block by way of the traction member fastener, and the other end of the traction member is connected to the driving member,

wherein the traction member is configured to drive the traction member fastener to rotate to cause the side impact protection block to switch from the folded position to the unfolded position.

2 . The side impact safety protection device according to claim 1 , wherein the side impact safety protection device further comprises a resetting member, wherein the resetting member is connected to the driving member, and is used to fold the side impact protection block through the driving member.

3 . The side impact safety protection device according to claim 1 , wherein the side impact safety protection device further comprises a torsion spring, and the torsion spring is disposed between the side impact protection block and the traction member.

4 . The side impact safety protection device according to claim 3 , wherein the torsion spring is sheathed on the pivot of the side impact protection block.

5 . The side impact safety protection device according to claim 1 , wherein the traction member fastener is fixedly arranged in the casing of the side impact protection block, and wherein the pivot of the side impact protection block passes through the traction member fastener.

6 . The side impact safety protection device according to claim 5 , wherein the side impact protection block and the traction member fastener are integrally formed.

7 . The side impact safety protection device according to claim 2 , wherein the driving member comprises a pressing end and a resetting end, the pressing end is exposed to outside, and the resetting end is connected to the resetting member.

8 . The side impact safety protection device according to claim 2 , wherein the resetting member is a spring.

9 . The side impact safety protection device according to claim 1 , wherein the side impact protection block further comprises a rear cover, and the casing and the rear cover are snap-fitted to each other to form a cavity.

10 . A child safety seat, comprising:

a body;

a base, on which the body is mounted; and

the side impact safety protection device according to claim 1 , arranged on the base.

11 . The child safety seat according to claim 10 , wherein a protection block receiving groove is disposed on a side surface of the base, and the side impact protection block of the side impact safety protection device is capable of being accommodated in the protection block receiving groove.

12 . The child safety seat according to claim 10 , wherein a pressing end of the driving member of the side impact safety protection device is exposed outside an upper surface of the base.

13 . A base adapted to carry a seating device, comprising:

a body, having at least one protrusion located on at least one of two sides of the body close to its front edge; and

the side impact safety protection device according to claim 1 , arranged on the at least one protrusion.

14 . The side impact safety protection device according to claim 2 , wherein the side impact safety protection device further comprises a torsion spring, and the torsion spring is disposed between the side impact protection block and the traction member.

15 . The side impact safety protection device according to claim 14 , wherein the torsion spring is sheathed on the pivot of the side impact protection block.

16 . The child safety seat according to claim 11 , wherein a pressing end of the driving member of the side impact safety protection device is exposed outside an upper surface of the base.

17 . A side impact safety protection device, comprising:

a side impact protection block, including a casing and a pivot disposed in the casing;

a driving member, for driving the side impact protection block to an unfolded position or a folded position;

a traction member, wherein one end of the traction member is connected to the pivot of the side impact protection block, and the other end of the traction member is connected to the driving member; and

a torsion spring which pushes the side impact protection block towards a direction of the folded position,

wherein

in response to the driving member not being triggered, the torsion spring pushes the side impact protection block to the folded position, and

in response to the driving member being triggered, the driving member drives the side impact protection block to switch from the folded position to the unfolded position.
